INCLUDED DOCUMENTS Included in this report is a document entitled "Proposals in Relation to Schemes of Arrangement" (the "SCHEME DOCUMENT"), which was sent by Marconi plc ("PLC") and Marconi Corporation plc ("CORP") to certain of their creditors on March 31, 2003, in connection with their proposed financial restructuring. The proposed restructuring will be effected by means of two UK Schemes of Arrangement, one each for Corp and plc. A Scheme of Arrangement is a court-supervised procedure under English law through which a company may enter into a compromise with its creditors to effect a restructuring of its financial obligations. The Scheme Document contains an Explanatory Statement required by Section 426 of the UK Companies Act 1985, explaining and summarizing the terms, conditions and mechanics of the Schemes of Arrangement. Copies of both Schemes of Arrangement, appendixes setting forth various aspects of the proposed restructuring in greater detail, and certain other information are also included in the Scheme Document.

The statements contained in this document are made as at the date of this document, unless another time is specified in relation to them, and delivery of this document shall not give rise to any implication that there has been no change in the facts set forth in this document since that date. Nothing contained in this document shall constitute a warranty or guarantee of any kind, express or implied, and nothing contained in this document shall constitute any admission of any fact or liability on the part of Corp or plc or any Affiliate of Corp or plc with respect to any asset to which it or they may be entitled or any claim against it or them. Without prejudice to the generality of the foregoing, nothing in the Schemes or the Explanatory Statement or the distribution thereof evidences to any person, or constitutes any admission by Corp, plc, the Prospective Supervisors or KPMG, that a liability is owed to any person in respect of any claim or that any person is or may be a Scheme Creditor of Corp or plc. The failure to distribute this document to any Scheme Creditor shall not constitute an admission by Corp, plc, the Prospective Supervisors or KPMG that such person is not a Scheme Creditor or that any liability owed to such person is an Excluded Claim. No person has been authorised by Corp or plc to make any representations concerning the Schemes which are inconsistent with the statements contained in this document and, if made, such representations may not be relied upon as having been so authorised. This document is issued solely in connection with the Schemes. If both the Corp Scheme and the plc Scheme are, or just the Corp Scheme is, approved by the relevant Scheme Creditors, a fairness hearing before the Court is necessary in order to sanction the approved Scheme or Schemes. All Scheme Creditors are entitled to attend the Court hearing in person or through counsel to support or oppose the sanctioning of the relevant Scheme or Schemes. It is expected that the Court hearing will be held on 12 to 13 May 2003 at the Royal Courts of Justice, Strand, London WC2A 2LL. Notice of the fairness hearing will be published, following approval of the Corp Scheme or both Schemes by relevant Scheme Creditors, in The Times and the international editions of the Wall Street Journal, the Financial Times and the International Herald Tribune. Lazard and Morgan Stanley are advising Corp and plc and no one else in connection with aspects of the Restructuring and will not be responsible to anyone other than Corp or plc for providing the protections afforded to their clients or for providing advice in connection with the Restructuring. Application has been made to the UKLA for the New Shares, the New Notes and the Warrants to be admitted to the Official List of the UKLA, and to the London Stock Exchange for the New Shares, the New Notes and the Warrants to be admitted to trading on the London Stock Exchange's market for listed securities. It is expected that admission to listing and trading will become effective and dealings in the New Shares, the New Notes and the Warrants will commence at 8.00 a.m. London time on 19 May 2003. However, see part I, Section 2, Part F.2: Risk Factors.

The issue of New Shares and New Notes to persons resident in the states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont will be subject to the limitations described in part I, Section 2, Parts C.9 and D.16. This document does not constitute an offer to sell or the solicitation of an offer to buy nor will there be any sale or distribution of the New Shares, the New Notes and the Warrants to be issued pursuant to the Schemes in any jurisdiction in which such offer or sale is not permitted.

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) -------------------------------------------------------------------------------- IMPORTANT NOTICE A. INFORMATION An explanation to assist you in determining if you are a Scheme Creditor, a Bondholder or another person with an interest in Bonds is set out in the section headed "Scheme Creditors and persons with interests in Bonds" on pages 8 to 11 of this document. Nothing in this document or any other document issued with or appended to it should be relied on for any purpose other than to make a decision on the Schemes. In particular and without limitation, nothing in this document or any other document issued with or appended to it should be relied on in connection with the purchase of any shares, warrants, bonds, notes or assets of Corp or plc. This document has been prepared in connection with proposals in relation to schemes of arrangement pursuant to section 425 of the Act between Corp and the Corp Scheme Creditors and plc and the plc Scheme Creditors. The information contained in this document concerning: (a) Corp only has been prepared by Corp; (b) plc only has been prepared by plc; and (c) both Corp and plc has been prepared by Corp and plc; and, in each case, that information has been prepared based upon information available to the relevant company. To the best of Corp's and plc's knowledge, information and belief, the information contained in this document is in accordance with the facts and does not omit anything likely to affect the import of such information. The financial statements have been prepared in accordance with UK GAAP. There may be differences between the way in which they are presented and the presentation of financial statements in public filings in other jurisdictions. Corp and plc have taken all reasonable steps to ensure that this document contains the information reasonably necessary to enable Scheme Creditors to make an informed decision about the effect of the relevant Schemes on them. The members of the Informal Committee of Bondholders and the Co-ordination Committee agreed, at an early stage of the Restructuring discussions, to enter into confidentiality agreements which, inter alia, acknowledged that Corp and plc would supply the Informal Committee of Bondholders and the Co-ordination Committee with certain material non-public information which could potentially make them "insiders" within the meaning of section 52 of the Criminal Justice Act 1993 and for the purposes of laws governing the trading of securities in England and Wales and other jurisdictions. Corp and plc have been required by the members of the Informal Committee of Bondholders pursuant to their confidentiality agreements to make public in this document all insider information, material non-public information or information that is price sensitive which has been supplied to the members of the Informal Committee of Bondholders by Corp or plc. Corp and plc believe that they have performed this obligation and that the members of the Informal Committee of Bondholders have no insider information, material non-public information or information that is price sensitive which has been supplied to them by Corp or plc. Certain information supplied to the Informal Committee of Bondholders and the Co-ordination Committee is not included in this document either because such information is of a commercially sensitive nature and public disclosure may affect Corp's, plc's or the Group's business or because such information was provided for illustrative purposes only, and in each case Corp and plc do not believe that the information is reasonably necessary to enable Scheme Creditors to make an informed decision on the Schemes nor, in the case of information supplied to the Informal Committee of Bondholders, do they believe such information is price sensitive. None of Corp's and plc's financial and legal advisers, the Prospective Supervisors, the members of the Informal Committee of Bondholders and the Co-ordination Committee and their respective financial and legal advisers, the Eurobond Trustee and the Yankee Bond Trustee and their respective advisers, who engaged in discussions or consulted with Corp and plc and their advisers concerning the Restructuring and/or who assisted with the distribution of documentation relating to the Schemes, the submission of claims and/or the voting procedures in respect of the Schemes, has verified that the information contained in this document is in accordance with the facts and does not omit anything likely to affect the import of such information and each of these persons expressly disclaims responsibility for such information. 1

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) IMPORTANT NOTICE -------------------------------------------------------------------------------- In accordance with normal practice, none of the Prospective Supervisors, the members of the Informal Committee of Bondholders and the Co-ordination Committee, the Eurobond Trustee and the Yankee Bond Trustee expresses any opinion as to the merits of the Schemes. Although the Prospective Supervisors have been involved in certain of the arrangements for formulating the Schemes, they make no recommendation as to how to vote in relation to the Schemes. The Prospective Supervisors, the members of the Informal Committee of Bondholders and the Co-ordination Committee, the Eurobond Trustee and the Yankee Bond Trustee recommend that Scheme Creditors who are in any doubt as to the impact on them of the Schemes (or either of them) seek their own financial, taxation and legal advice. The Prospective Supervisors, the members of the Informal Committee of Bondholders and the Co-ordination Committee, the Eurobond Trustee and the Yankee Bond Trustee express no opinion with respect to the effect of the Schemes on the rights or remedies afforded to Scheme Creditors under the US Trust Indenture Act of 1939 or otherwise. Nothing contained in this document shall be deemed to be a forecast, projection or estimate of plc's, Corp's or the Group's future financial performance except where otherwise specifically stated. This document contains certain statements, statistics and projections that are or may be forward-looking. The accuracy and completeness of all such statements, including, without limitation, statements regarding the Group's (or any Affiliate's, including Corp's or plc's) future financial position, strategy, projected costs, plans and objectives for the management of future operations, is not warranted or guaranteed. These statements typically contain words such as "intends", "expects", "anticipates", "estimates" and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. Although Corp and plc believe that the expectations reflected in such statements are reasonable, no assurance can be given that such expectations will prove to be correct. There are a number of factors which could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, factors identified in part I, Section 2, Part F, Risk Factors or elsewhere in this document as well as: future revenues being lower than expected; increasing competitive pressures in the industry; general economic conditions or conditions affecting the relevant industries, both domestically and internationally, being less favourable than expected; and/or conditions in the securities markets being less favourable than expected. In announcing the conclusion of the Heads of Terms in respect of the Restructuring on 29 August 2002, and an addendum to the Heads of Terms on 16 December 2002, the Group published certain financial projections with respect to the years ending 31 March 2004 to 31 March 2007. In announcing further information about the Restructuring on 18 March 2003, the Group published an illustrative financial analysis with respect to the year ending 31 March 2005. In the announcements the Group explained that the projections and analysis were prepared for internal purposes only and not with a view to public disclosure. In order to facilitate the Restructuring discussions, however, the Group furnished these projections and this analysis to representatives of the Syndicate Banks and members of the Informal Committee of Bondholders involved in the discussions. The projections and analysis were made public pursuant to the express terms of Corp's and plc's confidentiality agreements with the members of the Informal Committee of Bondholders. As indicated at the time of their publication, no reliance should be placed on these projections or this analysis and neither Corp nor plc will be publishing any updates in relation to them. No opinion is expressed as to the reasonableness of the assumptions on which the projections or analysis were prepared nor is any assurance given as to the occurrence, timing or extent of any market recovery. Accordingly, Corp and plc do not accept any responsibility for these projections or this analysis. In this document, references to "sterling", "L", "pence" or "p" are to the lawful currency of the United Kingdom, references to "dollars", US dollars", "cents", "US$" or "$" are to the lawful currency of the United States and references to "euro", "Euro" or "E" are to the currency introduced at the start of the third stage of the European economic and monetary union pursuant to the Treaty of Rome establishing the European Union, as amended. The summary of the principal provisions of the Schemes contained in this document is qualified in its entirety by reference to the Schemes themselves, the full texts of which are set out at parts II and III of this document. Each Scheme Creditor and each person with an interest in Bonds, is advised to read and consider carefully the texts of 2

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) IMPORTANT NOTICE -------------------------------------------------------------------------------- the Schemes themselves. This is because this document and, in particular, the Explanatory Statement have been prepared solely to assist Scheme Creditors in respect of voting on the Schemes. Scheme Creditors and persons with interests in Bonds should not construe the contents of this document as legal, tax, financial or other advice, and should consult with their own professional advisers as to the matters described in this document. B. SECURITIES LAW CONSIDERATIONS If the Corp Scheme becomes effective, New Shares and New Notes will be issued by Corp to the Escrow Trustee for distribution to Scheme Creditors, Designated Recipients and plc Shareholders, and Warrants will be issued by Corp to the Registrars for distribution to plc Shareholders, all in accordance with the Corp Scheme. If the plc Scheme also becomes effective, New Shares and New Notes which plc is entitled to receive by virtue of any of its Subsidiaries being a Scheme Creditor in the Corp Scheme are expected to form part of the plc Scheme Consideration which will be distributed to plc Scheme Creditors and Designated Recipients in accordance with the plc Scheme. The distribution of this document, New Shares, New Notes or Warrants may be restricted by law in certain jurisdictions. No action has been taken by Corp or plc that would permit an offer or distribution of New Shares, New Notes or Warrants or possession or distribution of this document or any offer or publicity material in any jurisdiction where action for that purpose is required, other than in the United Kingdom and in certain other jurisdictions referred to in part I, Section 2, Part D.18. Scheme Creditors, persons with interests in Bonds, Designated Recipients and plc Shareholders are strongly advised to consult their professional advisers as to whether any laws or regulations which may be applicable to them may give rise to any liability or penalty, or require them to obtain any government or other consents or to pay any taxes or duties, as a result of the implementation of the Schemes. None of Corp, plc, the Escrow Trustee, the Distribution Agent, the Supervisors, Bondholder Communications, the Registrars, the Informal Committee of Bondholders, the Co-ordination Committee, their respective directors or any other parties involved in the Restructuring accept any responsibility for any liabilities (including but not limited to consequential liabilities) incurred by Scheme Creditors, Definitive Holders, Designated Recipients and other persons with interests in Bonds or plc Shareholders as a result of the implementation of the Schemes in respect of laws or regulations applicable to them (except that UK stamp duty or SDRT payable in connection with the issuance of ADRs will be met by Corp to the extent described herein). Securities will not be distributed pursuant to the Schemes to or to the order, or for the account or benefit, of any person where such distribution would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous. To the extent that such a prohibition applies, securities that would otherwise have been distributed to any relevant person pursuant to the Schemes will be sold and the net cash proceeds of such sale (after deduction of all applicable expenses and currency conversion costs) paid to that person in sterling in full satisfaction of his rights in respect of such securities under the relevant Scheme (provided that if the securities are not listed on a securities exchange Scheme Creditors and Bondholders will be entitled to receive a sum in cash in sterling that is substantially equivalent in value to such securities). For further information, please see part I, Section 2, Part C.9. Corp and plc have determined that no such legal or regulatory prohibitions currently apply in connection with the Schemes with respect to the laws of the United Kingdom and certain other jurisdictions identified in part I, Section 2, Part C.9, but that such prohibitions do apply with respect to the laws of certain "Restricted Jurisdictions" (namely France, Italy, Malaysia and the US states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont). In connection with these restrictions and in order to permit securities to be distributed to persons located in Restricted Jurisdictions, the Claim Form will require each person completing it (other than the Trustees), and the Account Holder Letter will require each relevant Account Holder, to confirm certain facts. Except as otherwise described herein, if the required confirmations are not given in the form requested in a Claim Form or Account Holder Letter, then New Shares and New Notes will not be distributed in respect of such Claim Form or Account Holder Letter, in which case the relevant person or persons will receive cash instead as described above. Scheme Creditors, Definitive Holders, Designated Recipients and other persons with interests in Bonds -- in particular, those located in the Restricted Jurisdictions named above -- should carefully consider the provisions 3

It is also possible that the drawing up of the order 5

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) EXPECTED TIMETABLE OF PRINCIPAL EVENTS -------------------------------------------------------------------------------- or orders of the Court sanctioning one or both of the Schemes may be delayed if any person appeals the relevant order or orders. (3) All Scheme Claims are determined as at the Record Date. The Supervisors will be entitled to exercise discretion as to whether they recognise any assignment or transfer of Scheme Claims after the Record Date. Bonds may continue to be traded after the Record Date until the date on which they are blocked in the clearing systems. (4) A brief description of the claim against the relevant Scheme Company and other information must be provided in the Claim Form in respect of each Scheme Claim. Claim Forms are to be submitted to KPMG (Philip Wallace and Richard Heis, both partners in KPMG, are the Prospective Supervisors of both Schemes). Scheme Consideration will be distributed to Admitted Scheme Creditors by the Distribution Agent acting upon instructions received from the Escrow Trustee and the Supervisors. Scheme Creditors are urged to return their Claim Forms as soon as possible to allow as long as possible for them to be processed and checked by KPMG, thereby increasing the likelihood of Scheme Claims being Admitted (if appropriate) in time for Scheme Creditors to participate in the First Initial Distribution. KPMG will acknowledge receipt of each Claim Form received. Scheme Creditors requiring any assistance in completing Claim Forms should contact the HELPLINE on +44(0) 20 7694 3007. (5) No Scheme Consideration will be distributed by the Distribution Agent in relation to the Bonds except to Designated Recipients in respect of the relevant Scheme Claim identified in duly completed Account Holder Letters. Provided that the relevant Trustee has submitted a Claim Form which has been Admitted in time for the First Initial Distribution of Scheme Consideration to be made to Designated Recipients, for a Designated Recipient to receive the First Initial Distribution a copy of a duly completed Account Holder Letter relating to that Designated Recipient must be delivered in accordance with the instructions set out in Appendix 28 and must be received by Bondholder Communications by 5.00 p.m. (New York City time) on 17 April 2003. Holders of Eurobonds will receive the cash forming part of the First Initial Distribution whether or not an Account Holder Letter has been delivered by this date. (6) Each Definitive Holder identified in a duly completed Account Holder Letter is entitled to vote at the Scheme Meetings. The procedures in this respect are described in detail in Appendix 28. (7) KPMG will acknowledge receipt of each Form of Proxy received. Scheme Creditors (other than Definitive Holders, to whom this note is not applicable) requiring any assistance completing Forms of Proxy should contact the HELPLINE on +44(0) 20 7694 3007. Forms of Proxy may be handed in at the registration desk for the Scheme Meetings no later than one hour before the scheduled time of the relevant Scheme Meeting. Thereafter, Forms of Proxy may be handed to the chairman of the relevant Scheme Meeting at that meeting. All Scheme Creditors are recommended to return the relevant Form of Proxy on or before 5.00 p.m. on 17 April 2003 to minimise administrative delays. The latest time and date by which KPMG should receive Forms of Proxy is 12 noon on 24 April 2003. Faxed Forms of Proxy are acceptable if faxed to +44 (0)20 7694 3011. Faxes should be marked for the attention of Philip Wallace and Richard Heis. Scheme Creditors whose claims have been admitted and valued as described in note (10) below are entitled to attend and vote at the Scheme Meetings in person even if they have previously submitted a Form of Proxy. (8) The exchanges of Bonds are expected to be made shortly before the release of the interim security. (9) This is the date on which it is expected that the interim security (described in part I, Section 2, Part D.1) will be released. (10) The Corp Scheme Meeting will commence at the time stated and the plc Scheme Meeting will commence at the later of the time stated and the conclusion or adjournment of the Corp Scheme Meeting. The chairman of the relevant Scheme Meeting will admit and value claims of Scheme Creditors (including Definitive Holders) only for the purpose of voting at that Scheme Meeting and not for the purposes of determining whether a Scheme Claim should be Admitted. More detail concerning valuation of claims for the purposes of voting, admission of claims for the purposes of Scheme Meetings, and disputes as to such valuation or admission, is set out in paragraphs 15 to 17 of Appendix 27 and paragraphs 52 and 54 of Appendix 28. Only those Scheme Creditors whose claims have been so admitted and valued by the chairman of the relevant Scheme Meeting can vote at that Scheme Meeting. If, for this purpose only, a claim is rejected or reduced, the chairman will inform the relevant creditor of such rejection or reduction and report all such rejections or reductions of claims (with reasons therefor) to the Court at the hearing to sanction the relevant Scheme. (11) The Court will be requested to hear the petitions to sanction the Schemes together at a single hearing if both Schemes are approved by the relevant Scheme Creditors. The date for that hearing has not yet been settled, although it is expected to take place on or about 12 to 13 May 2003. If this date changes, the dates of all subsequent steps, including the Effective Date, will be affected. In this event, the date of the hearing will be published in The Times and the international editions of the Wall Street Journal, the Financial Times and the International Herald Tribune and also announced at each of the Scheme Meetings, to the extent then known. (12) The date of the US Bankruptcy Court hearing has not yet been determined. (13) If a Scheme Creditor (including a Definitive Holder) wishes to propose itself to act as a member of the Creditors' Committee, it should ensure that the appropriate box on its Claim Form or Account Holder Letter is ticked. On the Effective Date, the Supervisors will, to the extent possible, appoint up to seven members of the Creditors' Committee 6

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) EXPECTED TIMETABLE OF PRINCIPAL EVENTS -------------------------------------------------------------------------------- selected from those Scheme Creditors and Definitive Holders who have proposed themselves to act, representing a proper balance of the interests of Scheme Creditors as a whole. If fewer than three Scheme Creditors and Definitive Holders propose themselves to act as members of the Creditors' Committee, then on and from the Effective Date the Creditors' Committee will consist of as many members as have proposed themselves to act. In accordance with the terms of the Scheme those members, if any, will endeavour to fill the vacancy/vacancies to ensure that the Creditors' Committee has a minimum of three members within 28 days of the Effective Date. If those members do not succeed in appointing the necessary number of further members of the Creditors' Committee, resulting in a Creditors' Committee consisting of fewer than three members within 28 days of the Effective Date, the Supervisors will thereafter use reasonable endeavours to appoint the necessary number of further members within the following 14 days as interim committee members to serve on the Creditors' Committee until the necessary number of further permanent members are appointed. (14) Elections may be made in Claim Forms and Account Holder Letters to have all or any portion of the New Shares deliverable pursuant to the Schemes delivered in the form of ADRs. Corp will apply to list the ADRs on NASDAQ and will use its reasonable endeavours to effect this NASDAQ listing as soon as practicable following the Effective Date of the Corp Scheme. It is currently expected that the NASDAQ listing will become effective during the third calendar quarter of 2003. For further information, see part I, Section 2, Parts C.2 and D.15. (15) To receive Corp Scheme Consideration by way of the First Initial Distribution, a Corp Scheme Creditor's Scheme Claim must be approved by the Prospective Supervisors on or prior to 8.00 a.m. on the first day of the Court sanction hearing and the Claim Form in respect of that Scheme Claim must have been duly submitted by 5.00 p.m. on 17 April 2003. Corp Scheme Creditors are encouraged to return their Claim Forms as soon as possible, to allow as many Claim Forms as possible to be processed by KPMG in advance of 8.00 a.m. on the first day of the Court sanction hearing. This will allow as many Scheme Claims as possible, where appropriate, to be Admitted on the Effective Date and listed in the First Initial Distribution Notice pursuant to the terms of the Corp Scheme. Account Holders are encouraged to obtain whatever information or instructions they may require from Bondholders in sufficient time to enable them to return Account Holder Letters to Bondholder Communications as soon as possible and in any event prior to 5.00 p.m. (New York City time) on 17 April 2003. (16) To receive plc Scheme Consideration by way of the First Initial Distribution, a plc Scheme Creditor's Scheme Claim must be approved by the Prospective Supervisors on or prior to 8.00 a.m. on the first day of the Court sanction hearing and the Claim Form in respect of that Scheme Claim must have been duly submitted by 5.00 p.m. on 17 April 2003. plc Scheme Creditors are encouraged to return their Claim Forms as soon as possible, to allow as many Claim Forms as possible to be processed by KPMG in advance of 8.00 a.m. on the first day of the Court sanction hearing. This will allow as many Scheme Claims as possible, where appropriate, to be Admitted on the Effective Date and listed in the First Initial Distribution Notice pursuant to the terms of the plc Scheme. Account Holders are encouraged to obtain whatever information or instructions they may require from Bondholders in sufficient time to enable them to return Account Holder Letters to Bondholder Communications as soon as possible and in any event prior to 5.00 p.m. (New York City time) on 17 April 2003. (17) The Corp Capital Reduction (as more fully described in part I, Section 2, Part D.9) requires the sanction of the Court and the Court order confirming the Capital Reduction to be filed with the Registrar of Companies and registered by him. It is anticipated that these steps will take place on the dates indicated. 7

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) -------------------------------------------------------------------------------- SCHEME CREDITORS AND PERSONS WITH INTERESTS IN BONDS INTRODUCTION 1. For the purposes of this document, Scheme Creditors under the Corp and plc Schemes include bank creditors and certain other creditors of Corp and plc, respectively, at the Record Date (being 5.00 p.m. (London time) on 27 March 2003). Special provisions apply to the Yankee Bonds and Eurobonds as described below. A list of the Known Creditors of the Corp Scheme is set out in Schedule 3 to the Corp Scheme in part II of this document and a list of the Known Creditors of the plc Scheme is set out in Schedule 3 to the plc Scheme in part III of this document. YANKEE BONDS 2. The following Bonds issued by Corp and guaranteed by plc are Yankee Bonds: US$900,000,000 7 3/4 per cent. Bonds due 2010; and US$900,000,000 8 3/8 per cent. Bonds due 2030. The Yankee Bond Trustee and Book-Entry Depositary for both Yankee Bond issues is The Bank of New York. 3. For so long as each series of the Yankee Bonds remains in global form, The Bank of New York, as the bearer of the respective global Yankee Bonds, will be the Corp Scheme Creditor in respect of such Bonds. The Bank of New York, as Yankee Bond Trustee, is also a Corp Scheme Creditor in accordance with the terms of the Indenture. In these circumstances, none of the Account Holders, Intermediaries or Bondholders will be Corp Scheme Creditors and thus none of them will be entitled to attend or vote at the Corp Scheme Meeting. The Indenture permits the exchange of the global Yankee Bonds for definitive registered Yankee Bonds at Corp's discretion. At the request of certain creditors, Corp has agreed to exchange the global Yankee Bonds for definitive Yankee Bonds with a view to ensuring that Definitive Holders (being, in the case of the Yankee Bonds, the persons in whose names the Yankee Bonds in definitive form will be registered) can attend and vote in respect of such Bonds at the Corp Scheme Meeting. 4. The Bank of New York, as Yankee Bond Trustee, is also a plc Scheme Creditor by virtue of the guarantee given in its favour in the Indenture. At the request of certain creditors of plc, plc has agreed to extend the benefit of its guarantee of the Yankee Bonds to the Definitive Holders of Yankee Bonds with a view to ensuring that they can attend and vote at the plc Scheme Meeting in respect of such Bonds. 5. Under the Indenture, The Bank of New York, as the Yankee Bond Trustee, is entitled to, and will, file a Claim Form under each Scheme in respect of all of the Yankee Bonds. As a result, holders of Yankee Bonds should not file Claim Forms (except in respect of any non-Bond debt which is owed to such Bondholders by Corp or plc), but Account Holders who hold Yankee Bonds will need to file Account Holder Letters as described in paragraph 16 below in order for the nominated Definitive Holders to vote at the Scheme Meetings and the nominated Designated Recipients to receive Scheme Consideration in respect of each Scheme. 6. The procedures for filing a Claim Form, delivering an Account Holder Letter and attending and/or giving voting instructions in relation to the Scheme Meetings in relation to the Yankee Bonds are described in more detail in paragraph 16 below and in Appendix 28. EUROBONDS 7. The following Bonds issued by Corp and guaranteed by plc are Eurobonds: E500,000,000 5.625 per cent. Bonds due 2005; and E1,000,000,000 6.375 per cent. Bonds due 2010. The Eurobond Trustee for both Eurobond issues is The Law Debenture Trust Corporation p.l.c. 8. The Eurobond Trustee is a Corp Scheme Creditor in accordance with the terms of the Trust Deeds. For so long as each series of the Eurobonds remains in permanent global form, the common depositary for Euroclear and Clearstream, Luxembourg, as the bearer of the respective permanent global Eurobonds, will 8

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SCHEME CREDITORS AND PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- also be a Corp Scheme Creditor in respect of such Bonds. In these circumstances, none of the Account Holders, Intermediaries or Bondholders will be Corp Scheme Creditors and thus none of them will be entitled to attend or vote at the Corp Scheme Meeting. The terms of the existing permanent global Eurobonds do not permit their exchange for Eurobonds in definitive bearer form unless and until an event of default under the conditions of the Eurobonds or certain other limited events have occurred. However, at the request of certain creditors, Corp has agreed to exchange the permanent global Eurobonds for individual global Eurobonds with a view to ensuring that Definitive Holders (being, in the case of the Eurobonds, those persons who are bearers by attornment of the individual global Eurobonds) can attend and vote at the Corp Scheme Meeting in respect of such Bonds. Further details of the attornment process and the individual global Eurobonds are set out in paragraph 22 of Appendix 28. Corp has requested the Eurobond Trustee to agree that the terms of the global Eurobonds should be amended to permit the issuance of individual global Eurobonds at the discretion of Corp and the Eurobond Trustee has agreed to this request. Corp and the Eurobond Trustee have agreed the necessary amendments to the terms of the Trust Deeds to allow for the issue of individual global Eurobonds. 9. The Eurobond Trustee is also a plc Scheme Creditor by virtue of the guarantee given in its favour in the Trust Deeds. At the request of certain creditors of plc, plc has agreed to extend the benefit of its guarantee of the Eurobonds to the Definitive Holders of Eurobonds with a view to ensuring that they can attend and vote at the plc Scheme Meeting in respect of such Bonds. 10. The Eurobond Trustee, in its capacities as a Corp Scheme Creditor and a plc Scheme Creditor, is entitled to, and will, file a Claim Form under each Scheme in respect of all of the Eurobonds. As a result, holders of Eurobonds should not file Claim Forms (except in respect of any non-Bond debt which is owed to such Bondholders by Corp or plc) but Account Holders who hold Eurobonds will need to file Account Holder Letters as described in paragraph 17 below in order for the nominated Definitive Holders to vote at the Scheme Meetings and the nominated Designated Recipients to receive Scheme Consideration in respect of each Scheme. 11. The procedures for filing a Claim Form, delivering an Account Holder Letter and attending and/or giving voting instructions in relation to the Scheme Meetings in relation to the Eurobonds are described in more detail in paragraph 17 below and in Appendix 28. SCHEME CREDITORS 12. You are a Scheme Creditor if you have a Scheme Claim. For the purposes of this document, Corp Scheme Creditors include the Eurobond Trustee (in respect of the Eurobonds) and The Bank of New York (in respect of the Yankee Bonds), but do not include Bondholders (unless and until they become Definitive Holders), Account Holders or Intermediaries. In addition, plc Scheme Creditors include the Yankee Bond Trustee and the Eurobond Trustee but do not include Bondholders (unless and until they become Definitive Holders), Account Holders or Intermediaries. 13. The term "SCHEME CREDITOR" is used in this document in a number of different contexts and, in each context, has a different meaning in so far as the Bonds are concerned. In relation to the Bonds: - in the context of submitting Scheme Claims (and therefore completing Claim Forms) under both Schemes, the term "SCHEME CREDITOR" means only the Eurobond Trustee and the Yankee Bond Trustee; and - in the context of voting at Scheme Meetings and the right to attend Scheme Meetings and to be nominated to the Creditors' Committee under both Schemes, the term "SCHEME CREDITOR" means only the Definitive Holders. In the context of entitlement to receive Scheme Consideration under both Schemes, the term "SCHEME CREDITOR" is only used to mean those persons who have submitted a Scheme Claim which has been Admitted. Each Trustee is expected to submit a Scheme Claim and each such Scheme Claim is expected to be Admitted. However, as each Trustee will, in the Escrow and Distribution Agreement, direct that any Scheme Consideration to which it becomes entitled shall be distributed to Designated Recipients, in this 9

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SCHEME CREDITORS AND PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- context reference is generally made to Scheme Consideration being distributed to Scheme Creditors (other than the Trustees) and to Designated Recipients. PERSONS WITH INTERESTS IN BONDS 14. Persons with interests in Bonds include Account Holders, Intermediaries, Bondholders, Definitive Holders and Designated Recipients. The common depositary for Euroclear and Clearstream, Luxembourg has an interest in the Eurobonds by virtue of being the bearer of the global Eurobonds and The Bank of New York, in its capacity as Book-Entry Depositary, has an interest in the Yankee Bonds by virtue of being the holder of the global Yankee Bonds, in each case for so long as the Eurobonds or the Yankee Bonds, as the case may be, are represented by one or more global Eurobonds or global Yankee Bonds, respectively. You are: - an Account Holder if you are recorded directly in the books of Euroclear or Clearstream, Luxembourg as holding an interest in Eurobonds or Yankee Bonds or in the books of Euroclear, Clearstream, Luxembourg or DTC as holding an interest in Yankee Bonds, in each case in an account with the relevant clearing system; - an Intermediary if you hold an interest in Eurobonds or Yankee Bonds on behalf of another person or persons and you do not hold that interest as an Account Holder; - a Bondholder if you have the ultimate economic interest in the relevant Bonds; - a Definitive Holder if you are the registered holder of a Yankee Bond in definitive form or the bearer by attornment of an individual global Eurobond; and - a Designated Recipient if you are specified in an Account Holder Letter as being the recipient of cash and/or New Notes and/or New Shares in any distribution of Scheme Consideration in respect of a particular principal amount of Bonds. For the avoidance of doubt, a Bondholder may be the same person as the Designated Recipient and/or Definitive Holder of the Bonds relating to that Account Holder Letter. 15. IF YOU ARE A PERSON WITH AN INTEREST IN BONDS YOU SHOULD READ THIS DOCUMENT CAREFULLY AND TAKE THE APPROPRIATE ACTION DESCRIBED IN APPENDIX 28 IN ORDER FOR VOTING INSTRUCTIONS IN RELATION TO THE SCHEME MEETINGS TO BE GIVEN AND FOR DETAILS FOR THE PURPOSE OF RECEIVING SCHEME CONSIDERATION TO BE REGISTERED. 16. PERSONS WITH INTERESTS IN YANKEE BONDS SHOULD NOTE THAT: a. no Claim Form is required to be submitted by them as this will be done on their behalf by the Yankee Bond Trustee; b. Account Holders with interests in Yankee Bonds are recommended to deliver to Bondholder Communications (preferably on-line through www.bondcom.com/marconi) duly completed Account Holder Letters (in the form set out as the Annex to Appendix 28) on or before 5.00 p.m. (New York City time) on 17 April 2003 and, in order for this to be achieved, blocking instructions must be given by no later than 5.00 p.m. (in the place of the relevant clearing system) on the day before the Account Holder Letter is delivered to Bondholder Communications; c. delivery of a duly completed Account Holder Letter by the time and date specified in b. above will entitle Definitive Holders of Yankee Bonds to attend and/or vote at the Scheme Meetings and the Designated Recipients named in the applicable Account Holder Letter to receive the First Initial Distribution of Corp and plc Scheme Consideration and further distributions of Corp and plc Scheme Consideration (if any); d. failure to deliver an Account Holder Letter to Bondholder Communications by the time and date specified in b. above will not preclude the relevant Definitive Holder from voting at the Scheme Meetings provided that the Definitive Holder or his proxy can establish his entitlement 10

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SCHEME CREDITORS AND PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- by producing a copy of the duly completed Account Holder Letter or form of proxy, as the case may be; e. Definitive Holders of Yankee Bonds who wish to attend and vote in person at the Scheme Meetings must ensure that this is specified in the applicable Account Holder Letter. Definitive Holders of Yankee Bonds who wish only to have their vote recorded at the Scheme Meetings must ensure that authority is given to Bondholder Communications in the Account Holder Letter for the appointment of a proxy to vote on their behalf at the Scheme Meetings; and f. Account Holders who hold Yankee Bonds with ISIN US566306AA41 or ISIN US566306AB24 have received on 17 March 2003 an amount for distribution to Bondholders in respect of such Yankee Bonds representing interest accrued from and including 15 September 2002 to but excluding 15 October 2002 from the Yankee Bond Trustee which has been holding such amount on trust for the Bondholders of such Yankee Bonds. Amounts representing interest accrued to 15 October 2002 were paid to all other financial creditors of Corp on or about that date. 17. PERSONS WITH INTERESTS IN EUROBONDS SHOULD NOTE THAT: a. no Claim Form is required to be submitted by them as this will be done on their behalf by the Eurobond Trustee; b. Account Holders with interests in Eurobonds are recommended to deliver to Bondholder Communications duly completed Account Holder Letters (in the form set out in the Annex to Appendix 28) on or before 5.00 p.m. (New York City time) on 17 April 2003 and, in order for this to be achieved, blocking instructions must be given by no later than 5.00 p.m. (in the place of the relevant clearing system) on the day before the Account Holder Letter is delivered to Bondholder Communications; c. delivery of a duly completed Account Holder Letter by the time and date specified in b. above will entitle Definitive Holders of Eurobonds to attend and/or vote at the Scheme Meetings and the Designated Recipients named in the applicable Account Holder Letter to receive the First Initial Distribution of Corp and plc Scheme Consideration and further distributions of Corp and plc Scheme Consideration (if any). Account Holders will receive the cash forming part of the First Initial Distribution whether or not an Account Holder Letter is delivered; d. failure to deliver an Account Holder Letter to Bondholder Communications by the time and date specified in b. above will not preclude the relevant Definitive Holder from voting at the Scheme Meetings provided that the Definitive Holder or his proxy can establish his entitlement by producing a copy of the duly completed Account Holder Letter or form of proxy, as the case may be; and e. Definitive Holders of Eurobonds who wish to attend and vote in person at the Scheme Meetings must ensure that this is specified in the applicable Account Holder Letter. Definitive Holders of Eurobonds who wish only to have their vote recorded at the Scheme Meetings must ensure that authority is given to Bondholder Communications in the Account Holder Letter for the appointment of a proxy to vote on their behalf at the Scheme Meetings. GENERAL 18. IF YOU ARE A SCHEME CREDITOR, PLEASE READ THIS DOCUMENT CAREFULLY AND TAKE THE APPROPRIATE ACTION DESCRIBED IN APPENDIX 27. IF YOU ARE A PERSON WITH AN INTEREST IN BONDS, YOU SHOULD ALSO READ THIS DOCUMENT CAREFULLY AND BONDHOLDERS SHOULD CONTACT THEIR ACCOUNT HOLDERS (THROUGH ANY INTERMEDIARIES, IF APPROPRIATE) TO ENSURE THEY TAKE THE APPROPRIATE ACTION AS DESCRIBED IN APPENDIX 28. 11

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) -------------------------------------------------------------------------------- DEFINITIONS AND INTERPRETATION In this document, each Claim Form, each Account Holder Letter and each Form of Proxy, unless the context otherwise requires or otherwise expressly provides: a. words and expressions defined in part V on pages 995 to 1009 shall have the same meaning when used elsewhere in this document (other than in the Schemes set out in parts II and III of this document and the Schedules to them, the Escrow and Distribution Agreement set out in Appendix 7, the summary of the terms of the New Senior Notes and the New Junior Notes set out in Appendix 8, the security and intercreditor arrangements set out in Appendix 10 and the conditions of the Warrants set out in Appendix 12) and derivative terms shall be construed accordingly; b. references to Sections and Parts are references to the Sections and Parts of the Explanatory Statement as set out in part I of this document and references to Appendices are to the Appendices to the Explanatory Statement as set out in part IV of this document; c. references to a "person" include references to an individual, firm, partnership, company, corporation, unincorporated body of persons or any state or state agency; d. references to a statute or a statutory provision include the same as subsequently modified, amended or re-enacted from time to time; e. the singular includes the plural and vice versa and words importing one gender shall include all genders; and f. headings to parts, Sections, Parts and Appendices are for ease of reference only and shall not affect the interpretation of this document. The term "SCHEME CREDITOR" is used in this document in a number of different contexts and, in each context, has a different meaning in so far as the Bonds are concerned. In relation to the Bonds: a. in the context of submitting Scheme Claims under both Schemes, the term "SCHEME CREDITOR" means the Eurobond Trustee and the Yankee Bond Trustee; and b. in the context of voting at Scheme Meetings and the right to attend Creditors' Meetings and to be nominated to the Creditors' Committee under both Schemes, the term "SCHEME CREDITOR" means the Definitive Holders. In the context of entitlement to receive Scheme Consideration under both Schemes, the term "SCHEME CREDITOR" is only used to mean those persons who have submitted a Scheme Claim which has been Admitted. Each Trustee is expected to submit a Scheme Claim and each such Scheme Claim is expected to be Admitted. However, as each Trustee will, in the Escrow and Distribution Agreement, direct that any Scheme Consideration to which it becomes entitled shall be distributed to Designated Recipients, in this context reference is generally made to Scheme Consideration being distributed to Scheme Creditors (other than the Trustees) and to Designated Recipients. 12

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) -------------------------------------------------------------------------------- SUMMARY OF ACTION TO BE TAKEN Scheme Creditors to whom Corp and/or plc owes a Liability at the Record Date (other than those Liabilities defined in the relevant Schemes as Excluded Claims) are referred to Appendix 27 for more detailed instructions as to the action to be taken by them. Persons with interests in Bonds are referred to Appendix 28 for more detailed instructions as to the action to be taken by them. SCHEME CREDITORS Persons who are Scheme Creditors solely by virtue of having an interest in Bonds need not read paragraphs 1 to 3 below and should instead refer to paragraphs 4 to 7 below. 1. SCHEME MEETINGS Before the Schemes can become effective and binding on the Scheme Companies and their respective Scheme Creditors, resolutions to approve them must be passed by the statutory majority required by section 425 of the Act.

PERSONS WITH INTERESTS IN BONDS Scheme Creditors who are not also persons with interests in Bonds need not read paragraphs 4 to 7 below and should instead refer only to paragraphs 1 to 3 above. 4. BONDHOLDERS Bondholders should immediately contact their Account Holders (through any Intermediaries, if appropriate) to ensure that an Account Holder Letter is submitted in respect of the Bonds to which they are entitled. It is important that Account Holder Letters are submitted before 5.00 p.m. (New York City time) on 17 April 2003 and accordingly Bondholders should ensure that their Account Holders have all necessary information to enable them to meet this recommended deadline well before it occurs. Each Bondholder will need to identify a person as the Definitive Holder and one or more persons as Designated Recipient(s) in respect of the Bonds to which it is entitled. It is expected that in most cases the Bondholder will also be the Definitive Holder and Designated Recipient. Each Bondholder will also need to give his Account Holder instructions as to voting and the delivery of Scheme Consideration and will need to confirm certain matters in relation to applicable securities law, all as described in detail in Appendix 28. 5. ACCOUNT HOLDERS Duly completed Account Holder Letters should be delivered by each Account Holder to Bondholder Communications on line through www.bondcom.com/marconi, by post or personal delivery to Bondholder Communications at 30 Broad Street, 46th Floor, New York, N.Y. 10004, USA, attention Donna Martini, or to Bondholder Communications at 64 Queen Street, 3rd Floor, London EC4R 1AD, attention Donna Martini or by facsimile (Fax No: +1 212 422 0790 or + 44 207 236 0779, attention Donna Martini), as soon as possible. Duly completed Account Holder Letters must be delivered at or before 5.00 p.m. (New York City time) on 17 April 2003 in order for the Designated Recipients named in them to receive the First Initial Distribution of Scheme Consideration in the Corp and plc Schemes. Notwithstanding the foregoing, any cash forming part of the First Initial Distribution will be paid to Bondholders in respect of Eurobonds through Euroclear and Clearstream, Luxembourg regardless of whether an Account Holder Letter has been delivered or not. Duly completed Account Holder Letters delivered after 5.00 p.m. (New York City time) on 17 April 2003 will entitle the Designated Recipients to receipt of the Scheme Consideration in the Initial Distribution (excluding any cash already paid to them through Euroclear or Clearstream, Luxembourg) on the later of (1) as soon as is reasonably practicable following the date that the Account Holder Letter is delivered to Bondholder Communications and (2) the date of the First Initial Distribution. Please see Appendix 28 for more information in this regard. 14

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SUMMARY OF ACTION TO BE TAKEN -------------------------------------------------------------------------------- 6. SCHEME MEETINGS Definitive Holders are Scheme Creditors and therefore are entitled to vote at the Scheme Meetings. Definitive Holders who wish to attend and/or vote at the Scheme Meetings in person or by proxy must ensure that this is specified in the Account Holder Letter delivered by their Account Holder. Account Holders are recommended to deliver their Account Holder Letters to Bondholder Communications by 5.00 p.m. (New York City time) on 17 April 2003 in order to ensure that the Definitive Holder or his proxy can attend and vote at the Scheme Meetings. Delivery of Account Holder Letters after this time and date will not preclude the relevant Definitive Holder from voting at the Scheme Meetings provided that the Definitive Holder or his proxy can establish his entitlement in the manner described below and in Appendix 28. Each Definitive Holder who wishes to attend a Scheme Meeting in person will be required to register his attendance by presenting himself, together with a copy of the relevant Account Holder Letter, where possible, at the registration desk prior to the commencement of the relevant Scheme Meeting and, where an individual is attending on behalf of a body corporate and is not the authorised employee named in the Account Holder Letter, evidence of authorisation to represent that body corporate (for example a valid power of attorney and/or board minutes). A proxy (other than the chairman of the relevant meeting) for a Definitive Holder who attends a Scheme Meeting will need to provide a copy of his form of proxy and evidence of his personal identity (for example passport or other picture identification). Please see Appendix 28 for more information in this regard. 7. FORMS OF PROXY, CLAIM FORMS, ACCOUNT HOLDER LETTERS Persons with interests in Bonds should not complete a Claim Form or a Form of Proxy in the forms circulated with this document. Account Holders should deliver Account Holder Letters as described in paragraph 4 above. Account Holders with Bonds credited to their accounts at any of DTC, Euroclear or Clearstream, Luxembourg must obtain whatever information or instructions they may require to enable them to deliver an Account Holder Letter on behalf of the Bondholder in respect of those Bonds and Bondholders (through any Intermediaries, if appropriate) should ensure that they assist their Account Holder by providing him with all necessary information to enable him to do so. Definitive Holders who wish to attend and vote at the Scheme Meetings in person should receive a copy of the Account Holder Letter in which they are named as the Definitive Holder from the Account Holder with which they hold their Bonds. Definitive Holders who wish to attend and vote at the Scheme Meetings by proxy should request (and ensure that they receive) a copy of the relevant form of proxy from Bondholder Communications. It is the responsibility of each Bondholder and Definitive Holder to ensure that all necessary instructions are given to Bondholder Communications and the relevant Account Holder to facilitate receipt of these documents in time for the Definitive Holder or his proxy to attend and vote at the Scheme Meetings. 15

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) -------------------------------------------------------------------------------- SECTION 1 LETTER FROM THE CHAIRMAN OF PLC AND OF CORP (MARCONI LOGO) <Table> <S> <C> <C> MARCONI PLC MARCONI CORPORATION PLC New Century Park New Century Park P.O. Box 53 P.O. Box 53 Coventry Coventry Warwickshire Warwickshire CV3 1HJ CV3 1HJ (Registered in England with (Registered in England with registered number 3846429) registered number 67307) </Table> 31 March 2003 Dear Scheme Creditor or Bondholder, PROPOSED RESTRUCTURING OF CORP AND PLC (THE "RESTRUCTURING") On 29 August 2002 we announced that Corp and plc had concluded non-binding indicative Heads of Terms with the Co-ordination Committee and the Informal Committee of Bondholders, which set out the principles for the proposed Restructuring of Corp and plc. On 16 December 2002 we announced that we had concluded modifications to the non-binding indicative Heads of Terms by way of an addendum. On 7 February 2003 we announced that Corp and plc had reached agreement in principle with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group. On 18 March 2003 we announced that documentation in relation to the proposed Restructuring had been filed with the Court and provided an update on certain aspects of the Restructuring. Following our receipt on 26 March 2003 and 24 March 2003 respectively of the required consents to certain pre-completion steps for the Restructuring from the requisite majorities of the Syndicate Banks and the members of the Informal Committee of Bondholders, we are now writing to set out the terms of the Restructuring. This letter is part of an Explanatory Statement distributed to you for the reasons set out below and is qualified in its entirety by the more detailed information contained in the remainder of the Explanatory Statement. PURPOSE OF THE EXPLANATORY STATEMENT The Explanatory Statement, which is provided pursuant to section 426 of the Act, is distributed for the purpose of providing you with sufficient information to make an informed decision on whether or not to approve the Schemes. An explanation of the nature of the proposed Schemes is included below, as part of this letter. The main body of the Explanatory Statement (which follows this letter) is in six parts, containing information on the following matters: a. Business Overview; b. Background to and reasons for the Restructuring; c. Proposed Restructuring; d. General matters relating to the Restructuring; e. Material interests of Directors and Trustees; and f. Risk Factors. The Schemes will apply to all Corp Scheme Creditors and all plc Scheme Creditors, being those creditors of Corp and plc respectively whose claims the Corp Scheme and the plc Scheme will, if they become effective, compromise in accordance with their terms. The Corp Scheme is not conditional on the plc Scheme becoming effective. The plc Scheme will not become effective unless the Corp Scheme becomes effective. 16

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- The claims of Corp Scheme Creditors will be compromised in consideration for a distribution (pro rata to their Admitted Scheme Claims) of a package of cash, new equity and new debt securities of Corp. The liability of Corp in respect of those claims will be extinguished. The claims of plc Scheme Creditors will be compromised in consideration for a distribution in specie (pro rata to their Admitted Scheme Claims) of all of plc's assets net of a reserve in respect of plc's Ongoing Costs. plc's assets will principally comprise the package of cash, new equity and new debt securities of Corp which plc will receive as a result of the Corp Scheme from Bonds held by its subsidiary, Ancrane, and monies owed by Corp to Ancrane (as described further below). The liability of plc in respect of the claims of plc Scheme Creditors will be extinguished. You are being sent this document, including the Schemes, because the Scheme Companies believe that you may be either a Scheme Creditor under one or both of the Schemes or a person with an interest in Bonds. Pages 8 to 11 of this document will help you identify whether you are a Scheme Creditor or a person with an interest in Bonds. Scheme Creditors should direct any enquiries to the Prospective Supervisors, whose details are set out in Appendix 23. To facilitate communications with persons with an interest in Bonds, Corp and plc have appointed Bondholder Communications Group ("BONDHOLDER COMMUNICATIONS") to ensure Bondholders receive a copy of this document. Bondholder Communications will also be able to facilitate the completion of Account Holder Letters which need to be completed to enable most elements of Scheme Consideration to be distributed to Bondholders (see Appendix 28). Bondholder Communications's details are set out in Appendix 28. Each of the Scheme Companies strongly recommends that Scheme Creditors and persons with an interest in Bonds consider the Restructuring proposal carefully. This document contains details of the proposed Restructuring, including the Corp Scheme and the plc Scheme, which are to be voted on at meetings of Corp Scheme Creditors and plc Scheme Creditors, respectively, to take place on 25 April 2003 at 10.00 a.m. (London time) for Corp Scheme Creditors, and 10.15 a.m. (London time) for plc Scheme Creditors (or as soon as possible thereafter following the conclusion or adjournment of the first meeting). This document also explains why Corp and plc consider the proposed Restructuring to be in the best commercial interests of the Corp Scheme Creditors and the plc Scheme Creditors respectively, as well as in the wider interests of the Group, its employees and customers and plc Shareholders. FOR THE REASONS GIVEN IN THIS DOCUMENT, EACH OF CORP AND PLC RECOMMENDS THAT THE RELEVANT SCHEME CREDITORS VOTE IN FAVOUR OF ITS SCHEME AT THE RELEVANT SCHEME MEETING. AGREEMENT OF ANCRANE AND CORP NOT TO VOTE Ancrane, a wholly-owned subsidiary of plc, is a Bondholder in respect of E324,603,000 in principal amount of Eurobonds and US$261,101,000 in principal amount of Yankee Bonds, both of which are guaranteed by plc. Ancrane is also owed by Corp the sums of L363,308,102 under an intra-group loan and L14,635,059 under a reimbursement obligation in respect of Restructuring fees paid by Ancrane on behalf of Corp. Ancrane has undertaken not to attend or vote at the Scheme Meetings, not to take any steps to enable a vote to be cast on its behalf at the Scheme Meetings and to support the Restructuring by agreeing not to take any action to hinder or oppose the Schemes. Corp has a claim of L146,587,439 against plc. Corp has undertaken not to attend or vote at the plc Scheme Meeting and not to take any steps to enable a vote to be cast on its behalf at the plc Scheme Meeting. Neither Corp nor Ancrane nor any other member of the Group will vote at either of the Scheme Meetings. This is because Corp and plc believe that should the Scheme Meetings approve either of the Schemes by a small margin, including votes cast in respect of claims of members of the Group, the result could be unfair to any dissenting Scheme Creditors entitled to vote at the Scheme Meetings. BACKGROUND TO AND REASONS FOR THE PROPOSED RESTRUCTURING The Group has faced difficult trading conditions for some time. The impact of a period of rapid and unprecedented deterioration in the global telecommunications market has been compounded for the Group by the cost of a number of acquisitions made since 1998. These acquisitions, which were primarily for cash consideration, resulted in a substantial part of the debt burden being carried by the Group and, in the light of 17

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- reduced market demand for the Group's products and services, the trading and cash flow performances of these acquired businesses have been running at levels well below those that were anticipated at the time of acquisition. The Board of plc announced its intention, at its Annual General Meeting in July 2001, to initiate an operational review of the Group's business. The results of this review were announced in September 2001, along with the appointments of Michael Parton as Chief Executive Officer of plc, Derek Bonham as Interim Chairman of plc and Michael Donovan as Chief Operating Officer of plc as well as the management appointments of Neil Sutcliffe as chief executive officer of Marconi Capital and Geoffrey Doy as chief executive officer of sales and marketing of plc. Against a background of further market deterioration early in 2002, plc announced on 22 March 2002 that Corp and plc had decided not to enter into new banking facilities to refinance Corp's then existing syndicated bank facilities. Following this decision, Corp and plc agreed to cancel the undrawn commitments under the existing facilities and agreed that the drawn portion under the Bank Facility (which was due for repayment on 25 March 2003) would be repayable on demand. Following the decision not to refinance the then existing syndicated bank facilities the Business Plan was developed. This Business Plan was presented to the Co-ordination Committee and the Informal Committee of Bondholders and was used by Corp and plc as a basis for formulating the Heads of Terms for the Restructuring. The Business Plan assumed that recovery in the Group's market would not commence until the end of the calendar year 2003. A set of sensitivities were applied to reflect the scenario of more difficult market conditions, and in particular a delay in market recovery beyond the end of 2003. Given continuing uncertainty in market conditions, further revisions have been made to the Business Plan. In proposing the Restructuring, Corp and plc have assessed the proposed capital structure of Corp against the scenario of a delay in market recovery and are confident that the proposed capital structure of Corp is appropriate in circumstances where such a delay occurs. However, the Group cannot predict with any level of certainty the occurrence, timing or extent of any market recovery. WHY THE PROPOSED RESTRUCTURING NOW? The Group has for some time been in severe financial difficulty. In particular, Corp is the principal obligor under the Bank Facility, which was due for repayment on 25 March 2003, and is the issuer of the Bonds. Interest on the Yankee Bonds fell due on 17 March 2003 and interest on the Eurobonds will fall due on 31 March 2003. For both the Yankee Bonds and the Eurobonds acceleration of the principal amount is permitted following non-payment of interest 14 days after the respective interest due dates. plc is a guarantor of the Bank Facility and the Bonds. Corp and plc believe they must effect a restructuring of their financial obligations, including their obligations under the Bank Facility and the Bonds, to avoid a demand being made for repayment of sums owing under the Bank Facility or an acceleration of sums owing under the Bonds, which would inevitably lead to Corp and plc being placed into insolvency proceedings. The Corp Group's ability to continue to operate as a going concern following the Restructuring is subject to certain operating and other risks. You should carefully consider, together with the other information contained in this document, certain risks related to a failure or delay in implementing the Restructuring, risks arising from implementation of the Restructuring, operating risks and risks related to ownership of the New Shares, the New Notes and the Warrants, set out in Section 2, Part F: Risk Factors. All statements in this document (other than parts II and III) are to be read subject to, and are qualified in their entirety by, the matters referred to in Section 2, Part F: Risk Factors. THE SCHEMES CORP SCHEME Corp proposes to enter into a scheme of arrangement with the Corp Scheme Creditors pursuant to section 425 of the Act. The Corp Scheme takes effect as a compromise or arrangement between Corp and the Corp Scheme Creditors and will not directly affect any other creditors of Corp (described below in the section headed "Corp stakeholders"). Alongside the Corp Scheme, it is proposed to make changes to Corp's capital structure by way of the Capital Reduction, involving the cancellation of its current called up share capital and its share premium 18

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- account. It is expected that the reserve arising on the Capital Reduction will eliminate the deficit on the profit and loss account that would otherwise be shown on Corp's balance sheet as at 31 March 2003. Further details of the Capital Reduction are set out in Section 2, Part D.9. The Corp Scheme is set out in part II of this document. The Corp Scheme will become effective and legally binding on Corp and all Corp Scheme Creditors in accordance with its terms if: (i) at the meeting of the Corp Scheme Creditors a majority in number representing three-fourths in value of Corp Scheme Creditors present and voting either in person or by proxy approves the Corp Scheme (for the purposes of voting at the meeting of Corp Scheme Creditors, a Form of Proxy is enclosed with this document); (ii) the Court subsequently makes an order sanctioning the Corp Scheme; and (iii) the Court's order sanctioning the Corp Scheme is sealed and a copy of it is delivered for registration to the Registrar of Companies in England and Wales. Corp will not take the necessary steps to make the Scheme effective unless and until: (a) Corp has, following the passing of a unanimous Board resolution to approve the same, provided confirmation in writing to the Prospective Supervisors (for the sole benefit of the Prospective Supervisors) prior to each of (i) the release of the interim security granted by Corp through its special purpose subsidiary Highrose Limited, (ii) the Corp Scheme Meeting, (iii) the hearing to sanction the Corp Scheme and (iv) the Effective Date, to the effect that Corp remains satisfied that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors and that Corp remains of the opinion that its statement as to the Corp Group's working capital contained in Section 2, Part D.21 remains valid; (b) the Prospective Supervisors of the Corp Scheme have provided confirmation in writing to Corp (for Corp's sole benefit) on the day of, but prior to, each of events (i) to (iv) above to the effect that they have no reason to disagree with Corp's view that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors; (c) a permanent injunction order of the US Bankruptcy Court under Section 304 of Title 11 of the United States Code is granted in respect of the Corp Scheme; and (d) all conditions precedent (other than those relating to the Corp Scheme becoming effective) set out in the Working Capital Facility and the Performance Bonding Facility are satisfied or waived by the facility agents. If the English Court makes an order sanctioning the Corp Scheme, Corp anticipates that the order of the US Bankruptcy Court will be granted. Corp will not pursue a permanent injunction order of the US Bankruptcy Court unless the English Court makes an order sanctioning the Corp Scheme. If all of the above conditions are not satisfied by 19 June 2003 the Corp Scheme will be withdrawn. Corp will undertake to the Court to file the Court order approving the Corp Scheme with the Registrar of Companies as soon as the conditions set out above are satisfied provided such conditions are satisfied on or before 19 June 2003. The hearing to sanction the Corp Scheme will qualify as a fairness hearing of the kind contemplated by Section 3(a)(10) of the Securities Act. All Corp Scheme Creditors and Bondholders are entitled to attend the hearing in person or through counsel to support or oppose the sanctioning of the Corp Scheme. The Corp Scheme is not conditional on Listing of the New Shares, the New Notes and/or the Warrants. However, it is expected that the New Shares, the New Notes and the Warrants will be listed on the Effective Date of the Corp Scheme. Corp will use its reasonable endeavours to effect the Listing of the New Shares, the New Notes and the Warrants as soon as possible on or after the Effective Date of the Corp Scheme. PLC SCHEME plc proposes to enter into a scheme of arrangement with the plc Scheme Creditors pursuant to section 425 of the Act. The plc Scheme takes effect as a compromise or arrangement between plc and the plc Scheme Creditors and will not directly affect any other creditors of plc (described below in the section headed "plc stakeholders"). The plc Scheme will become effective and legally binding on plc and all plc Scheme Creditors in accordance with its terms if: (i) at the meeting of the plc Scheme Creditors a majority in number representing three-fourths in value of plc Scheme Creditors present and voting either in person or by proxy approve the plc Scheme (for the purposes of voting at the meeting of plc Scheme Creditors, a Form of Proxy is enclosed with this document); (ii) the Court subsequently makes an order sanctioning the plc Scheme; and (iii) the Court's order sanctioning the plc Scheme is sealed and a copy of it is delivered for registration to the Registrar of Companies in England and Wales. 19

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- plc will not take the necessary steps to make the Scheme effective unless and until: (a) plc has, following the passing of a unanimous Board resolution to approve the same, provided confirmation in writing to the Prospective Supervisors (for the sole benefit of the Prospective Supervisors) prior to each of (i) the release of the interim security granted by Corp through its special purpose subsidiary Highrose Limited, (ii) the plc Scheme Meeting, (iii) the hearing to sanction the plc Scheme and (iv) the Effective Date, to the effect that plc remains satisfied that the reserves built into the plc Scheme are sufficient to meet distributions due to be made to all plc Scheme Creditors; (b) the Prospective Supervisors of the plc Scheme have provided confirmation in writing to plc (for plc's sole benefit) on the day of, but prior to, each of events (i) to (iv) above to the effect that they have no reason to disagree with plc's view that the reserves built into the plc Scheme are sufficient to meet distributions due to be made to all plc Scheme Creditors; (c) a permanent injunction order of the US Bankruptcy Court under Section 304 of Title 11 of the United States Code is granted in respect of the plc Scheme; and (d) a copy of the Court's order sanctioning the Corp Scheme is delivered for registration to the Registrar of Companies in England and Wales. If the English Court makes an order sanctioning the plc Scheme, plc anticipates that the order of the US Bankruptcy Court will be granted. plc will not pursue a permanent injunction order of the US Bankruptcy Court unless the English Court makes an orders sanctioning both the Corp Scheme and the plc Scheme. If all of the above conditions are not satisfied by 19 June 2003 the plc Scheme will be withdrawn. plc will undertake to the Court to file the Court order approving the plc Scheme with the Registrar of Companies as soon as the conditions set out above are satisfied provided such conditions are satisfied on or before 19 June 2003. The hearing to sanction the plc Scheme will qualify as a fairness hearing of the kind contemplated by Section 3(a)(10) of the Securities Act. All plc Scheme Creditors and Bondholders are entitled to attend the hearing in person or through counsel to support or oppose the sanctioning of the plc Scheme. WHO WILL BE AFFECTED BY THE SCHEMES? CORP STAKEHOLDERS The Corp Scheme will take effect as a compromise of all creditors' claims against Corp at the Record Date, other than certain Excluded Claims, in consideration (pro rata to each Corp Scheme Creditor's Admitted Scheme Claim) of a distribution of cash, new equity and new debt securities of Corp. Claims that are denominated in a currency other than sterling will be converted into sterling: (a) for the purpose of calculating voting entitlements at the Corp Scheme Meeting, at the Voting Rate; and (b) for all other purposes, at the Scheme Rate. Details of the categories of Excluded Claims and the basis upon which they have been excluded are set out in Section 2, Part C.7 and in Appendix 9. The claims of creditors of Corp excluded from the Corp Scheme will not be directly affected by either the Corp Scheme or the plc Scheme and are expected to be satisfied in the ordinary course subject to the risk factors affecting the business of the Group detailed in Section 2, Part F: Risk Factors. Corp's existing shareholders have agreed, conditionally on the allotment and issue of the New Shares pursuant to the Corp Scheme, to the conversion of all of the existing ordinary shares in the capital of Corp into Non-Voting Deferred Shares. Therefore, Corp's existing shareholders will have no ordinary shares in Corp following the implementation of the Restructuring. The Non-Voting Deferred Shares are expected to be cancelled as part of the Capital Reduction a few days after the Effective Date. As a result of the Corp Scheme, plc Shareholders will receive (proportionate to their existing holdings in plc but subject to a minimum of one share per plc Shareholder), with no price payable, in aggregate 0.5 per cent. of Corp's issued ordinary share capital immediately following the Restructuring and up to 50 million Warrants exercisable at any time up to four years after the date of the Restructuring allowing for the subscription of additional ordinary shares equal to an aggregate of up to 5 per cent. of Corp's issued ordinary share capital immediately following the Restructuring. The Warrants, each of which will give the right to subscribe for one share (subject to adjustment to protect against dilution in the event of certain corporate actions), will have an exercise price per underlying ordinary share of 150p (again subject to adjustment to protect against dilution in the event of certain corporate actions). An ordinary share price of 150p implies a post Restructuring market capitalisation of Corp of L1.5 billion. 20

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- Further details of the changes to Corp's capital structure are set out below under the heading "Equity Dilution". Details of certain share incentive plans that will operate post Restructuring are set out in Section 2, Part D.10. PLC STAKEHOLDERS The plc Scheme will take effect as a compromise of all creditors' claims against plc at the Record Date, other than certain Excluded Claims, in consideration for a distribution (pro rata to each plc Scheme Creditor's Admitted Scheme Claim) of plc's assets available for distribution to Scheme Creditors (which, at the Effective Date of the plc Scheme, will comprise all of plc's assets less a reserve comprising cash of approximately L9,300,000 in respect of plc's Ongoing Costs). Claims that are denominated in a currency other than sterling will be converted into sterling: (a) for the purpose of calculating voting entitlements at the plc Scheme Meeting, at the Voting Rate; and (b) for all other purposes, at the Scheme Rate. Details of the categories of Excluded Claims and the basis upon which they have been excluded are set out in Section 2, Part C.7 and in Appendix 9. plc's Excluded Claims include, amongst other things, claims in respect of unclaimed dividends, the gross amount of which is no more than L278,451. In an insolvent liquidation of plc the claims of creditors in respect of unclaimed dividends ("dividend creditors") would be subordinated to the claims of all other creditors. They are therefore in a different class from the other creditors of plc. There are three ways in which they could be treated: they could be included in the plc Scheme and treated in the same manner as other creditors; they could be excluded from the Scheme and left unpaid on the ground that with their subordinated status they have no real economic interest in plc's assets; or they could be excluded from the plc Scheme and paid if and when a valid claim is made. The first way of treating such claims would involve a separate class meeting of dividend creditors. This has been rejected because it would be excessively expensive to identify them, to send this document to each of them and, in the event that the recipients of this document did make claims, to administer their claims and distribute plc Scheme Consideration to them. As a practical matter it would be necessary to provide that the plc Scheme could take effect even if, at the separate class meeting of creditors in this category, the statutory majority (or a sufficient representative turnout) was not obtained, and this would remove any incentive for the class to vote in favour of the plc Scheme. The second way would leave them with unpaid claims against plc in their capacity as creditors and could therefore result in an insolvent liquidation of plc. This approach has been rejected because if this were to occur in the early stages of the implementation of the Schemes, it may have implications for the reputation of the Marconi name and accordingly may impact upon the trust of third parties to deal with members of the Corp Group going forward. In addition, given the fact that almost all claims would in any event be excluded as de minimis, the decision was taken to exclude whatever other claims of this nature remain outstanding. It is therefore proposed that they will be excluded from the plc Scheme and paid if and when a valid claim is made. Accordingly, an amount of L278,451 will be set aside for the purposes of paying any claims in respect of previously unclaimed dividends on plc Shares. Upon termination of the plc Scheme, arrangements will be put in place to ensure that this amount is set aside to pay such claims as and when a claim is made. Save as regards the treatment of the unclaimed dividends, which would otherwise be subordinated to the general body of unsecured creditors, the rights and ranking afforded to plc's creditors under the plc Scheme is intended to reflect the rights and ranking that those creditors would have had in a liquidation of plc. The following obligations of plc have been novated to Corp (conditionally upon the Corp Scheme becoming effective) and will be excluded from the Corp Scheme: a. a guarantee provided to Finmeccanica SpA as the purchaser of certain Italian subsidiaries sold by the Group in 2002; b. certain agreements between plc and BAE in respect of the merger of the Group's former defence business with BAE; and c. a licence agreement dated 1 December 1999 between Lemelson Medical, Education and Research Foundation, Limited Partnership and plc. 21

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- In addition, the service contracts and letters relating to retirement benefits (including FURBS) of Michael Parton and Michael Donovan have been novated to Corp unconditionally. The obligations listed above have (or will if the Corp Scheme becomes effective) become obligations of Corp and therefore will be unaffected by the plc Scheme. These obligations will also be excluded from the compromise to be effected by the Corp Scheme and will therefore be unaffected by the Corp Scheme. plc Scheme Creditors include creditors with contingent claims against plc, for example under guarantees. The Syndicate Banks, the Eurobond Trustee and the Yankee Bond Trustee are all plc Scheme Creditors because plc has guaranteed the Bank Facility, the Eurobonds and the Yankee Bonds. Each of the Trust Deeds and the Indenture contains a clause which provides that the guarantee given by plc in respect of the Bonds will terminate on certification by Corp to the Eurobond Trustee or the Yankee Bond Trustee, as the case may be, that plc has been unconditionally and irrevocably released from its obligations in respect of the Bank Facility (in the case of the Eurobonds) or that plc has been unconditionally and irrevocably released from its obligations in respect of the Bank Facility and the Eurobonds (in the case of the Yankee Bonds). This would not be the case if plc was wound up, but would be the case if these obligations were released under the plc Scheme. Various concerns were raised by either or both of the Informal Committee of Bondholders and the Co-ordination Committee during the course of the Restructuring discussions concerning the maintenance of guarantee claims against plc, including the potential lapse of the plc guarantee in respect of the Bonds, and arrangements were put in place in order to deal with these concerns. In making its decision to approve these arrangements, plc took into consideration that it was correct in principle that the rights should be preserved, in order to put the creditors concerned in the same position as if both Scheme Companies had been wound up. The arrangements are as follows: a. the Corp Scheme will provide that no Scheme Claim under the Corp Scheme will be reduced, or in any way affected, by the compromise of any claims of the relevant Scheme Creditor against plc pursuant to the terms of the plc Scheme, and vice versa; b. the execution by plc of a deed poll which provides that in the event that a Scheme Creditor who has the benefit of a guarantee in respect of a Corp Scheme Claim is required to give credit to plc in a liquidation for any recoveries made under the Corp Scheme, plc will pay to that creditor a further sum equal to the amount of the distribution that the creditor received in the Corp Scheme; and c. the entry by Corp and plc into a bondholder confirmation letter, to ensure that the guarantee in respect of the Bonds does not fall away before the relevant Trustees become entitled to claim under the plc Scheme on behalf of the Bondholders and that the plc guarantee is extended to Definitive Holders. By the Termination Date (as defined in the plc Scheme) all the assets of plc will have been distributed, in accordance with the plc Scheme, to the plc Scheme Creditors. It is envisaged that at that date there will be no further claims against, or assets held by, plc. It is intended that, following that date, plc will be liquidated or dissolved. plc has been granted a waiver by the UKLA from the requirement to obtain approval for the Restructuring from plc Shareholders. EQUITY DILUTION The entire issued ordinary share capital of Corp is currently owned by plc and its nominee. Immediately following completion of the Restructuring, Scheme Creditors and the Escrow Trustee (in its capacity as trustee of the Scheme Consideration for the benefit of the Scheme Creditors) or its nominee will collectively own 99.5 per cent. of the entire issued ordinary share capital of Corp and plc Shareholders will collectively own the remaining 0.5 per cent. of the entire issued ordinary share capital of Corp. The existing ordinary shares of Corp will be redesignated and converted into Non-Voting Deferred Shares upon allotment of the New Shares under the Corp Scheme. It is intended that those Non-Voting Deferred Shares will be cancelled as part of the Capital Reduction within a few days after the Effective Date of the Corp Scheme. The rights and restrictions attaching to the 22

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- Non-Voting Deferred Shares are described in Appendix 15. The ordinary share capital of Corp following the Restructuring will, however, be subject to dilution resulting from the future exercise of the Warrants referred to above and of options granted under the share incentive plans (details of which are contained in Section 2, Part D.10). Save as referred to above, no other entitlements have been granted for participation in the share capital of Corp as from implementation of the Restructuring. SUMMARY OF THE PRINCIPAL TERMS OF THE SCHEMES CORP SCHEME If the Corp Scheme becomes effective, all Corp Scheme Creditors will be bound by its terms. Corp will be fully and completely released by the Corp Scheme Creditors from all obligations of Corp to the Corp Scheme Creditors in connection with their Scheme Claims against Corp with effect from the earlier of the date on which their Scheme Claim is Admitted and is the subject of a Distribution Notice, the Final Distribution Date under the Corp Scheme, and the issue of a Termination Notice under the Corp Scheme. In consideration for such cancellation and release, Corp Scheme Creditors will receive a distribution, pro rata to their Admitted Scheme Claims, of: a. L340 million cash; b. the euro equivalent (calculated at the Currency Rate) of L450 million in aggregate principal amount of new guaranteed senior secured notes due April 2008 to be issued by Corp denominated in euro and/or US dollars, subject to elections made in Claim Forms and Account Holder Letters, with interest payable quarterly in cash at a rate of 8 per cent. per annum; c. the sum of US$300 million plus the US dollar equivalent (calculated at the Currency Rate) of L117.27 million in aggregate principal amount of new guaranteed junior secured notes due October 2008 to be issued by Corp denominated in US dollars with interest payable quarterly in cash at a rate of 10 per cent. per annum or, at Corp's option, in kind (by issuing additional new junior secured notes) at a rate of 12 per cent. per annum; and d. 995,000,000 ordinary shares, representing 99.5 per cent. of the issued ordinary share capital of Corp immediately following the implementation of the Restructuring. The cash element of the distribution will be increased by the net proceeds of any asset disposals, other than L82 million of excluded asset disposal proceeds, received on or after 1 December 2002 and before 1 May 2003, and the aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of the sterling amount by which the cash element is increased (such calculation to reduce the L117.27 million figure referred to in c. above). Such net proceeds received on or after 1 May 2003 will be dealt with in accordance with the terms of the New Notes. The cash, New Shares, New Senior Notes and New Junior Notes comprise the Corp Scheme Consideration. Further details of the terms of the New Senior Notes and New Junior Notes are contained in Section 2, Part C.3 and Appendix 8 of this document. Details of the guarantee and security arrangements in respect of the New Notes are contained in Appendix 10. Corp will establish an ADR programme and, accordingly, elections may be made in Claim Forms and Account Holder Letters to receive all or a portion of the New Shares in the form of ADRs. It is expected that the New Shares, New Notes and Warrants will be listed on the Official List and admitted to trading on the London Stock Exchange's market for listed securities on the Effective Date of the Corp Scheme. Corp has applied to list the New Shares, New Notes and Warrants and will use its reasonable endeavours to effect the Listing as soon as possible on or after the Effective Date of the Corp Scheme. The Corp Scheme is not, however, conditional on this Listing (see details of risks arising from implementation of the Restructuring in Section 2, Part F.2). Corp will apply to list its ADRs on NASDAQ and will use its reasonable endeavours to effect this NASDAQ listing as soon as practicable following the Effective Date of the Corp Scheme. It is currently expected that the NASDAQ listing will become effective during the third calendar quarter of 2003. 23

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- If the Corp Scheme becomes effective, plc Shareholders will receive New Shares and Warrants as referred to above. First Initial Distribution The mechanism for calculating and distributing a Corp Scheme Creditor's entitlement to receive Corp Scheme Consideration is detailed in the Corp Scheme set out in part II and is also described in more detail in Section 2, Part C.7. Both these sections should be read carefully. The Corp Scheme provides that a First Initial Distribution will take place on the Effective Date of the Corp Scheme. At the Court hearing to sanction the Corp Scheme, Corp will present to the Court a schedule of Scheme Claims compiled by the Prospective Supervisors which will set out the details of the Scheme Creditors with Known Claims which are proposed to be Admitted by the Supervisors on the Effective Date and that, in accordance with the terms of the Corp Scheme, will receive their Initial Distribution through the First Initial Distribution. In summary, each Corp Scheme Creditor that participates in the First Initial Distribution will be entitled to receive (assuming no increase in the cash element but that the plc Scheme becomes effective on the same day as the Corp Scheme), for each L1,000,000 of Admitted Scheme Claim, an Initial Distribution of cash, New Notes and New Shares of approximately: L64,196 cash; L85,022 equivalent in aggregate principal amount of New Senior Notes (which will be denominated in euro and/or US dollars, subject to elections made in Claim Forms and Account Holder Letters); L58,177 equivalent in aggregate principal amount of New Junior Notes (which will be denominated in US dollars); and 187,993 New Shares. If the plc Scheme does not become effective on the same day as the Corp Scheme (or at all) the Corp/plc distribution model described in Section 2, Part C.7 under the heading "Circulation of Scheme Consideration and payments on a modelled basis" will not have been applied, and accordingly each of the numbers set out above will be reduced by between approximately 0.41 per cent. and 0.47 per cent. For the purposes of the above calculations, Known Claims that are denominated in a currency other than sterling and New Junior Notes that will be issued by reference to a US dollar amount have been converted at the Voting Rate. The final calculations as to Known Claims will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). The final calculations as to the principal amounts of the New Senior Notes and the New Junior Notes to be received by a Scheme Creditor on the First Initial Distribution will be made at the Currency Rate (which will be set the Business Day before the Corp Scheme Meeting). The Corp Scheme provides that a portion of the Corp Scheme Consideration will initially be used to meet Known Claims that have been identified prior to the Record Date. On such a Known Claim becoming Admitted in the Corp Scheme, the Corp Scheme Creditor with that Known Claim will be entitled to receive the portion of the Corp Scheme Consideration designated to meet that Known Claim. Corp has undertaken extensive due diligence and advertised in newspapers in the UK, the US and elsewhere in order to identify its creditors and ensure that all Corp Scheme Creditors are included in the schedule of Known Claims. Corp has also written to its Known Creditors that will be affected by the Corp Scheme with the exception of certain financial creditors with Known Claims who have been represented in negotiations with Corp and plc regarding the development of the Restructuring proposals of Corp and plc, creditors for unclaimed interest and redemptions on loan notes issued by Corp whose potential claims are easily quantified and are provided for in full, and those whose addresses Corp has been unable to ascertain. With the exception of two claims (one apparently against Corp) which were clearly frivolous, the advertising process identified no claims which had not previously been identified by Corp's due diligence. In addition to the Known Claims that have been identified, the Corp Scheme includes a reserve of Scheme Consideration that would be able to meet the payment of an Initial Distribution in respect of Scheme Claims which are Admitted for up to L125 million, which Corp is satisfied will 24

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- be sufficient to cover any other Scheme Claims that had not been identified by the Record Date. The Prospective Supervisors have confirmed that they have no reason to disagree with Corp's view that the reserve is sufficient. However, a mechanism has been put in place to ensure that Corp will not proceed with the Corp Scheme and will withdraw the Scheme if, prior to the Effective Date of the Corp Scheme, it becomes apparent that there may be Scheme Claims against Corp which are not Known Claims and Corp is not satisfied that the reserve will be sufficient to meet distributions due to be made out of it or if the Prospective Supervisors do not confirm that they have no reason to disagree with Corp's view that the reserve is sufficient. Details of this mechanism are set out in Section 2, Part C.7. If the Corp Scheme is withdrawn then the plc Scheme will also be withdrawn. If at any time after the issue of the First Initial Distribution Notice, which will occur on the Effective Date, the Supervisors are not satisfied that the reserve will be sufficient to meet distributions due to be made out of it, then the remaining Scheme Consideration set aside to meet Known Claims and the remaining reserve will be aggregated and all Further Distributions under the Corp Scheme will be made out of the remaining Scheme Consideration, on a strictly pari passu basis. PLC SCHEME The plc Admitted Scheme Creditors will be entitled to receive a distribution pro rata to their Scheme Claims out of plc's assets which are available for distribution to plc Admitted Scheme Creditors. Assuming the Corp Scheme becomes effective, plc's assets will principally comprise the cash, New Shares and New Notes that plc receives under the Corp Scheme from Bonds held by Ancrane and from monies owed by Corp to Ancrane (as described above). plc's entitlement to this Scheme Consideration will arise from a repayment of capital in specie by Ancrane to plc of all of its assets other than L100. The plc Scheme provides that plc will set aside the sum of L7,000,000 from the cash element of Corp Scheme Consideration it receives via Ancrane which, together with plc's cash of approximately L2,300,000, interest on the aggregate of these two cash amounts and L2,000,000 available to be drawn (at Corp's request) under a letter of credit to be provided in favour of the plc Scheme Supervisors from time to time by HSBC Bank plc pursuant to the Performance Bonding Facility described below, will be available to meet plc's Ongoing Costs. plc's Ongoing Costs are estimated to be a maximum of L11,300,000 plus an amount which will be covered by the interest referred to above, and will include: a. the costs of plc, the Supervisors, the Escrow Trustee, the Distribution Agent and their respective advisers in implementing the Restructuring and administering the plc Scheme; b. any costs plc or the Supervisors incur in continuing to defend Allowed Proceedings (including any adverse costs orders); c. the payment of any claims which are to be excluded from the plc Scheme and which have not been novated to Corp which represent all claims as at the Record Date which would have been preferential in a liquidation and claims in respect of unpaid dividends which in a liquidation would have been subordinated; and d. any ongoing administrative costs of plc, including the preparation and filing of accounts, the holding of any annual general meetings that are required to be held under the Act and the costs of plc's eventual dissolution or liquidation. Any monies remaining following the payment of plc's Ongoing Costs will be distributed to all plc's Admitted Scheme Creditors in the Final Distribution under the plc Scheme. Subject to any limitations under applicable securities laws, the assets plc receives from Ancrane will be distributed to the plc Scheme Creditors in specie (i.e. in the form in which they are held, and not realised for cash prior to distribution). Any other assets of plc are expected to be converted into cash before distribution. 25

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- First Initial Distribution The mechanism for calculating and distributing a plc Scheme Creditor's entitlement to receive plc Scheme Consideration is detailed in the plc Scheme set out in part III and is also described in more detail in Section 2, Part C.7. Both these sections should be read carefully. The plc Scheme provides that a First Initial Distribution will take place on the Effective Date of the plc Scheme, at the same time as the First Initial Distribution under the Corp Scheme. At the Court hearing to sanction the plc Scheme, plc will present to the Court a schedule of Scheme Claims compiled by the Prospective Supervisors which will set out details of the Scheme Creditors with Known Claims which are proposed to be Admitted by the Supervisors on the Effective Date and that, in accordance with the terms of the plc Scheme, will receive their Initial Distribution through the First Initial Distribution. The Initial Distribution available to all plc Scheme Creditors will comprise all the Scheme Consideration received by plc via Ancrane as a result of Ancrane's entitlement to an Initial Distribution in the Corp Scheme (net of the sum of L7,000,000 set aside on account of plc's Ongoing Costs). Scheme Claims that have been Admitted by the Effective Date will receive their Initial Distribution through the First Initial Distribution. Corp has the benefit of a Scheme Claim of L146,587,439 against plc. If this Known Claim is Admitted in the plc Scheme in full (which Corp expects to be the case) Corp will become entitled to receive its pro rata entitlement in respect of its Admitted Scheme Claim in the First Initial Distribution under the plc Scheme. Both Corp and plc have agreed to distribute any Scheme Consideration they receive as a result of this claim to their respective Scheme Creditors by way of Additional Scheme Consideration. Further details of these payments are set out in Section 2, Part C.7 below under the heading "Circulation of Scheme Consideration and payments on a modelled basis". In summary, each plc Scheme Creditor that participates in the First Initial Distribution in the plc Scheme will be entitled to receive (assuming no increase in the cash element of the Corp Scheme Consideration but that the plc Scheme becomes effective on the same day as the Corp Scheme), for each L1,000,000 of Admitted Scheme Claim an Initial Distribution of cash, New Notes and New Shares of approximately: L9,446 cash; L14,554 equivalent in aggregate principal amount of New Senior Notes (which will be denominated in euro and/or US dollars, subject to elections made in Claim Forms and Account Holder Letters); L9,959 equivalent in aggregate principal amount of New Junior Notes (which will be denominated in US dollars); and 32,182 New Shares. If the plc Scheme does not become effective on the same day as the Corp Scheme the Corp/plc distribution model described in Section 2, Part C.7 under the heading "Circulation of Scheme Consideration and payments on a modelled basis" will not have been applied, and accordingly each of the numbers set out above will be reduced by approximately 8.51 per cent. For the purposes of the above calculations, Known Claims that are denominated in a currency other than sterling and New Junior Notes that will be issued by reference to a US dollar amount have been converted at the Voting Rate. The final calculations as to Known Claims will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). The final calculations as to the principal amounts of the New Senior Notes and the New Junior Notes to be received by a Scheme Creditor on the First Initial Distribution will be made at the Currency Rate (which will be set the Business Day before the Corp Scheme Meeting). The plc Scheme provides that a portion of plc's assets available for distribution will be used to meet Known Claims that have been identified prior to the Record Date. On such Known Claim becoming Admitted in the plc Scheme, the plc Scheme Creditor with that plc Scheme Claim will be entitled to receive the portion of the plc Scheme Consideration designated to meet that Known Claim. plc has undertaken extensive due diligence and advertised in newspapers in the UK, the US and elsewhere in order to identify its creditors and ensure that all plc Scheme Creditors are included in the Schedule of Known 26

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- Claims. plc has also written to all of its Known Creditors that will be affected by the plc Scheme with the exception of certain financial creditors with Known Claims who have been represented in negotiations with Corp and plc regarding the development of the Restructuring proposals of Corp and plc, and those whose addresses plc has been unable to ascertain. With the exception of one claim (which is disputed by plc, but is provided for in full in the plc Scheme), the advertising process identified no claims which had not been previously identified by plc's due diligence. In addition to the claims that have been identified, the plc Scheme includes a reserve of Scheme Consideration that would be able to meet the payment of an Initial Distribution in respect of Scheme Claims which are Admitted for up to L250 million, which plc is satisfied will be sufficient to cover any other Scheme Claims that have not been identified by the Record Date. The Prospective Supervisors have confirmed that they have no reason to disagree with plc's view that the reserve is sufficient. However, a mechanism has been put in place to ensure that plc will not proceed with the plc Scheme and will withdraw the Scheme if prior to the Effective Date of the plc Scheme it becomes apparent that there may be Scheme Claims against plc which are not Known Claims and plc is not satisfied that the reserve will be sufficient to meet distributions due to be made out of it or if the Prospective Supervisors do not confirm that they have no reason to disagree with plc's view that the reserve is sufficient. Details of this mechanism are set out in Section 2, Part C.7. In any event, if the Corp Scheme is withdrawn then the plc Scheme will also be withdrawn, but the Corp Scheme will not be withdrawn only because the plc Scheme is withdrawn. If at any time after the issue of the First Initial Distribution Notice, which will occur on the Effective Date, the Supervisors are not satisfied that the reserve will be sufficient to meet distributions due to be made out of it, then the remaining Scheme Consideration set aside to meet Known Claims and in the reserve will be aggregated and all Further Distributions under the plc Scheme will be made out of the remaining Scheme Consideration, on a strictly pari passu basis. AGGREGATE FIRST INITIAL DISTRIBUTIONS FROM BOTH SCHEMES If a Scheme Creditor has an Admitted Scheme Claim in the Corp Scheme, which is guaranteed by plc, and the claim under the guarantee is Admitted in the plc Scheme, or vice versa, and that Scheme Creditor participates in the First Initial Distributions in both the Corp and plc Schemes, then that Scheme Creditor will be entitled to receive (assuming no increase in the cash element of the Corp Scheme Consideration but that the two Schemes become effective on the same day) for each L1,000,000 of Admitted Scheme Claims an aggregate Initial Distribution of cash, New Notes and New Shares of approximately: L73,642 cash; L99,576 equivalent in aggregate principal amount of New Senior Notes (which will be denominated in euro and/or US dollars, subject to elections made in Claim Forms and Account Holder Letters); L68,136 equivalent in aggregate principal amount of New Junior Notes (which will be denominated in US dollars); and 220,175 New Shares. If the plc Scheme does not become effective on the same day as the Corp Scheme the Corp/plc distribution model described in Section 2, Part C.7 under the heading "Circulation of Scheme Consideration and payments on a modelled basis" will not have been applied, and accordingly each of the numbers set out above will be reduced by between approximately 1.45 per cent. and 1.65 per cent. For the purposes of the above calculations, Known Claims that are denominated in a currency other than sterling and New Junior Notes that will be issued by reference to a US dollar amount have been converted at the Voting Rate. The final calculations as to Known Claims will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). The final calculations as to the principal amounts of the New Senior Notes and the New Junior Notes to be received by a Scheme Creditor on the First Initial Distribution will be made at the Currency Rate (which will be set the Business Day before the Corp Scheme Meeting). 27

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- LEGAL RESTRICTIONS ON DISTRIBUTION OF SECURITIES Securities will not be distributed pursuant to the Schemes where this would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous. To the extent that such a prohibition applies, securities that would otherwise have been distributed to any relevant person pursuant to the Schemes will be sold and the net cash proceeds of such sale (after deduction of all applicable expenses and currency conversion costs) will be paid to that person in full satisfaction of his rights in respect of these securities under the relevant Scheme (provided that if the securities are not listed on a securities exchange Scheme Creditors and Bondholders will be entitled to receive a sum in cash that is substantially equivalent in value to such securities). In order to permit the distribution of securities pursuant to the Schemes, the Claim Form will require persons completing it (other than the Trustees), and the Account Holder Letter will require Account Holders, to confirm certain facts. For further information, see Section 2, Part C.9. Any persons who are in doubt as to how legal or regulatory restrictions may affect them in relation to the Schemes are strongly advised to consult their professional advisers. POST RESTRUCTURING WORKING CAPITAL In order to support the Group's working capital requirements following the Restructuring, Corp and Marconi Bonding Limited have entered into the Performance Bonding Facility (a L50 million committed performance bonding facility provided by HSBC Bank plc and JPMorgan Chase Bank) and Marconi Communications, Inc. has entered into the Working Capital Facility (a US$22.5 million revolving facility provided by Liberty Funding, L.L.C.). The Performance Bonding Facility is conditional on the Corp Scheme becoming effective. Further details of each of these facilities are set out in Section 2, Part D.4. Information on the Corp Group's financial objectives is set out in Section 2, Part A.7. INTERIM SECURITY AND SUPPORT FOR THE RESTRUCTURING As part of the arrangements to effect the Restructuring, Corp agreed to provide interim security to its principal lenders, being the Syndicate Banks (in their capacities as Syndicate Banks, bilateral lenders to Corp and beneficiaries of guarantees from Corp (in such capacities, "BANK CREDITORS")), the holders of the Bonds from time to time (apart from plc's wholly owned subsidiary Ancrane) and the Trustees (together, the "SECURED BONDHOLDERS") and Barclays Bank PLC (as the only ESOP Derivative Bank which committed to support the Restructuring prior to 15 October 2002). The interim security was taken over cash held by Highrose Limited, a special purpose subsidiary of Corp and plc, in accounts held with third party banks (the "LOCKBOX ACCOUNTS"). These interim security arrangements took effect on 13 September 2002, on which date the balance held in the Lockbox Accounts was approximately L866,000,000. The interim security arrangements were amended on 13 December 2002 and were further amended on 28 March 2003. As at 27 March 2003, the balance held in the Lockbox Accounts was approximately L770,700,000. Without this interim security, the Syndicate Banks (as comprised at the time) and the Informal Committee of Bondholders would not have been prepared to continue to support the Restructuring, and insolvency proceedings would have been the only practicable alternative. On 26 March 2003 and 24 March 2003 respectively the requisite majorities of the Syndicate Banks and the members of the Informal Committee of Bondholders agreed an extension of time in which to complete the Restructuring and a waiver of enforcement events which may then have existed in relation to the interim security. In addition, the requisite majorities of the Syndicate Banks and the members of the Informal Committee of Bondholders, in contemplation of the Restructuring: (a) consented, for the purposes of the undertakings given in favour of the Syndicate Banks and the Informal Committee of Bondholders, to the entry by Corp, plc and other Group companies into certain transactions (including those contemplated under the Scheme Implementation Deed) necessary to facilitate the Restructuring; and (b) agreed a number of additional carve-outs to those undertakings to permit Corp, plc and other Group Companies to enter into transactions contemplated in this document (provided that, subject to some exceptions, such transactions do not take effect until the Effective Date of the Corp Scheme). 28

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- In addition, in connection with the ESOP Settlement Agreement referred to below, UBS AG, Citibank, N.A. and Barclays Bank PLC have each provided a voting undertaking in relation to the Corp Scheme and the plc Scheme (further details of which are set out in part I, Section 2, Part D.2). Provision has been made for the interim security to be released prior to the Corp Scheme Meeting in circumstances tied to the prospects of the Corp Scheme being successfully implemented (as described more fully in Section 2, Part D.1). If the interim security has not been released prior to the Corp Scheme Meeting neither Corp nor plc will proceed with their respective Schemes, and the interim security will remain in place in any subsequent insolvency proceedings, meaning that the Bank Creditors, Secured Bondholders and Barclays Bank PLC would rank ahead of all unsecured creditors of Corp with respect to the cash held in the Lockbox Accounts. If the interim security is released and the Corp Scheme Meeting proceeds, the choice facing all Corp Scheme Creditors will be the same; either the Corp Scheme will be approved and implemented, or the Corp Scheme will be rejected and in the inevitable insolvency proceeding which would follow such rejection the interim security would no longer be in place. The Syndicate Banks and the Informal Committee of Bondholders have indicated that they will not be prepared to release the interim security prior to the Corp Scheme Meeting unless, immediately before such release, Corp has confirmed to the Prospective Supervisors that Corp remains satisfied that the reserves built into the Corp Scheme are sufficient to meet distributions to all Corp Scheme Creditors and that Corp remains of the opinion that its statement as to the Corp Group's working capital contained in Section 2, Part D.21 remains valid, and the Prospective Supervisors have confirmed to Corp that they have no reason to disagree with Corp's view that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors. SETTLEMENT OF ESOP DERIVATIVE CLAIMS On 26 March 2003, Corp and plc entered into a definitive agreement with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group. Under the terms of the settlement, which is conditional upon the Corp Scheme becoming effective, Corp will pay a total of L35 million to the ESOP Derivative Banks in full and final settlement of their ESOP related claims against the Group. This settlement amount will be paid from a fund of up to L170 million which was to have been set aside by Corp, as part of the Restructuring, pending resolution of potential liabilities of Group companies to Barclays Bank PLC, Salomon Brothers International Limited and UBS AG in relation to the Group's ESOP derivative arrangements. The settlement has made available approximately L135 million in cash which forms part of the L340 million comprising the cash element of the Corp Scheme Consideration. Without the ESOP settlement, the L135 million sum would not have formed part of the Corp Scheme Consideration. The Boards of Corp and plc believe that the ESOP settlement is in the best interests of Corp and plc and their respective stakeholders as a whole. In reaching this conclusion, the Boards of Corp and plc have taken appropriate legal advice from leading counsel and considered a number of relevant factors, including the merits of the claims of the ESOP Derivative Banks, the desire to reduce the cost and expense of continuing litigation, the potential saving in the interest burden from which the Group will benefit by settling the ESOP derivative dispute, the benefits for the Schemes and certainty as to the amount of the Corp Scheme cash distribution that such a settlement brings. RISKS ASSOCIATED WITH THE TIMING OF THE RESTRUCTURING When the Heads of Terms were announced in August 2002, plc indicated that the Restructuring was scheduled to be completed by 31 January 2003. This date was extended to 15 March 2003 in December 2002. As a result of the complexity of the Restructuring the Effective Date of the Schemes is now expected to be on or around 19 May 2003. The change to the timing of the Restructuring introduces risks associated with certain financial debt falling due in March 2003. In particular, the Bank Facility was due for repayment on 25 March 2003 and remains unpaid, an interest payment was due on the Yankee Bonds on 17 March 2003 and remains unpaid and an interest payment is due on the Eurobonds on 31 March 2003. In common with Corp's and plc's approach to other Scheme Claims, pending the outcome of the Schemes neither Corp nor plc intends to make payment in respect of such obligations, in whole or in part. Under the terms of the Bank Facility, unpaid amounts accrue interest at the 29

EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- default rates set out therein; namely LIBOR plus 3.25 per cent. per annum. For the purposes of participation in the Schemes, no such interest will accrue beyond the Record Date. The fact of the above mentioned payments falling due represents a risk to the Restructuring, due to consequential legal action which Syndicate Banks or Bondholders who are not supportive of the Restructuring process could take against Corp or plc. However, Corp and plc are of the view that, given the timing associated with any such legal action as well as the likely attitude of the English and New York Courts to a creditor seeking to frustrate the Restructuring (which is intended to be for the benefit of all Scheme Creditors), these risks should be manageable. This issue is discussed in more detail in Section 2, Part F: Risk Factors. WHAT HAPPENS IF EITHER OR BOTH OF THE SCHEMES DO NOT BECOME EFFECTIVE? The plc Scheme will not become effective unless the Corp Scheme becomes effective. Following the Corp Scheme being implemented, plc's assets available for distribution under the plc Scheme to the plc Scheme Creditors will principally comprise the assets received by it as a result of the repayment of capital by Ancrane. Ancrane, as a holder of Bonds issued by Corp and guaranteed by plc and pursuant to intra-group arrangements, will be entitled to its pro rata share of the Corp Scheme Consideration and the plc Scheme Consideration. Ancrane has been re-registered as an unlimited liability company to facilitate the transfer of its assets to plc by the repayment of capital in specie for distribution to plc Scheme Creditors under the plc Scheme. If the Corp Scheme does not become effective, the plc Scheme Consideration would be so significantly diminished that plc would not implement the plc Scheme and would be forced to commence an insolvency proceeding. If plc were subject to an insolvency proceeding, for the reasons set out under the heading "The alternative" below it is likely that there would be a lower rate of return for the plc Scheme Creditors as compared to their return if the plc Scheme became effective. Also, any return to plc creditors from an insolvency proceeding would be likely to be significantly delayed. The Corp Scheme is not conditional upon the plc Scheme becoming effective and Corp is satisfied that it will be able to implement the Corp Scheme whether or not the plc Scheme becomes effective. Corp is satisfied that, if the Corp Scheme is implemented, the Corp Group will be sufficiently ringfenced from plc that the Corp Group will be able to operate effectively, even if plc has been forced to commence an insolvency proceeding. THE ALTERNATIVE If the Corp Scheme becomes effective but the plc Scheme does not become effective, then plc would inevitably have to enter into some form of insolvency proceeding. If both of the Schemes do not become effective or are terminated before the First Initial Distribution, it is likely that Corp and plc would have to enter some form of insolvency proceedings. This is because, given the severity of the Group's financial position (including the fact that the Bank Facility was due for repayment on 25 March 2003 and remains unpaid, that an interest payment was due on the Yankee Bonds on 17 March 2003 and remains unpaid, and that an interest payment is due on the Eurobonds on 31 March 2003), the Board of the relevant Scheme Company would be likely to conclude that there was no reasonable prospect of avoiding an insolvency proceeding. The instigation of an insolvency proceeding in relation to Corp or both Corp and plc before either Scheme has become effective would be likely to result in insolvency proceedings for other principal Group companies. As referred to above, if the interim security has not been released prior to the Corp Scheme Meeting neither Corp nor plc will proceed with their respective Schemes. If the interim security is released and the Corp Scheme Meeting proceeds, the choice facing all Corp Scheme Creditors will be the same: either the Corp Scheme will be approved and implemented or the Corp Scheme will be rejected and in the inevitable insolvency proceeding which would follow such a rejection the interim security would no longer be in place. A detailed analysis of the position of Corp and plc should they be subject to insolvency proceedings (and the assumptions, caveats, limitations and uncertainties on which such analysis is based) is set out at Appendix 6. This analysis should be read carefully, including the caveats, limitations and uncertainties. Corp and plc believe that the Schemes are more beneficial to Scheme Creditors than insolvency proceedings or the enforcement of security and should result in a better return, greater certainty and an immediate day one distribution to Scheme Creditors. None of these benefits would be possible under the insolvency alternatives. 30

ACTION TO BE TAKEN SCHEME CREDITORS (OTHER THAN PERSONS WITH INTERESTS IN BONDS) If you are a Scheme Creditor, I urge you to complete and return the Claim Form and Form of Proxy to KPMG as soon as possible and before the recommended deadline set out below. To help you in completing these documents detailed instructions have been included in Appendix 27 and each document contains further guidance. If you have any queries in connection with the Claim Form or Form of Proxy, please contact KPMG using the Helpline described at the front of this document. BONDHOLDERS If you are a Bondholder, I urge you to contact your Account Holder (through any Intermediaries, if appropriate) to ensure that an Account Holder Letter is submitted in respect of your Bonds before the recommended deadline set out below. In order to vote at the Scheme Meetings, Bondholders will need to nominate a Definitive Holder (who may or may not be the Bondholder). This nomination must be made in the relevant Account Holder Letter. In order to do this your Account Holder will need instructions from you in relation to voting and the delivery of Scheme Consideration and will require certain securities laws confirmations. To help you in giving these instructions detailed guidance as to the various elections to be made and confirmations to be given has been included in Appendix 28. If you have any queries in this connection, please contact Bondholder Communications using the Helpline described at the front of this document. ACCOUNT HOLDERS If you are an Account Holder, I urge you to immediately contact your Bondholders (through any Intermediaries, if appropriate) for instructions to enable you to complete and return the Account Holder Letter to Bondholder Communications as soon as possible and before the recommended deadline set out below. Where possible, I urge you to complete this document on-line as this will minimise clerical errors. To help you in completing these documents detailed instructions have been included in Appendix 28. If you have any queries in connection with the Account Holder Letter, please contact Bondholder Communications using the Helpline described at the front of this document. RECOMMENDED DEADLINE FOR ACTION TO BE TAKEN It is recommended that Claim Forms and Forms of Proxy are submitted to KPMG before 5.00 p.m. (London time) on 17 April 2003 and that Account Holder Letters are submitted to Bondholder Communications before 5.00 p.m. (New York City time) on 17 April 2003. Forms of Proxy may be submitted to KPMG before 12 noon 31

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 1: LETTER FROM THE CHAIRMAN OF PLC AND OF CORP -------------------------------------------------------------------------------- (London time) on 24 April 2003. The Prospective Supervisors will undertake a review of all Claim Forms submitted prior to the Effective Date to determine whether the relevant Scheme Claims can be properly Admitted. No Scheme Claims submitted after the specified time on 17 April 2003 will be included in the First Initial Distribution Notice. Assuming that the Scheme Claims of the two Trustees are included in the First Initial Distribution Notice (which Corp and plc expect to be the case), no Designated Recipient named in an Account Holder Letter submitted after this date will receive the First Initial Distribution of Scheme Consideration. Submission of Forms of Proxy and Account Holder Letters after the recommended deadline on 17 April 2003 will not preclude a Scheme Creditor (including any Definitive Holder) from voting at the Scheme Meetings provided that the Scheme Creditor or his proxy is able to establish his identity and entitlement to vote at the relevant Scheme Meeting. RECOMMENDATION Corp and plc believe that, given the Group's financial position, the proposed Restructuring is in the best interests of all stakeholders, including Scheme Creditors, Bondholders and plc Shareholders. If the Restructuring is not approved, the severity of the Group's financial position is such that Corp and plc would have no reasonable prospect of avoiding insolvency proceedings which would mean that there would be a lower return to Scheme Creditors, accompanied by uncertainty and delay, and no return whatsoever to plc Shareholders. ACCORDINGLY, CORP RECOMMENDS THAT CORP SCHEME CREDITORS (INCLUDING DEFINITIVE HOLDERS) VOTE IN FAVOUR OF THE CORP SCHEME AT THE CORP SCHEME MEETING AND PLC RECOMMENDS THAT PLC SCHEME CREDITORS (INCLUDING DEFINITIVE HOLDERS) VOTE IN FAVOUR OF THE PLC SCHEME AT THE PLC SCHEME MEETING.

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) -------------------------------------------------------------------------------- SECTION 2 FURTHER EXPLANATION OF THE RESTRUCTURING A. BUSINESS OVERVIEW A.1 BACKGROUND The Group is a global vendor of telecommunications equipment and services. The Group's customers include many of the leading telecommunications operators throughout the world, with whom it has a large base of installed equipment. This document sets out proposals which, if implemented, will result in Corp becoming the new holding company of the Group. It is intended that all of plc's assets (which derive principally from the claim of plc's subsidiary Ancrane in the Corp Scheme in respect of its holding of Bonds and monies owed to it by Corp), net of a reserve in respect of plc's Ongoing Costs, will be distributed over time to the creditors of plc in accordance with the plc Scheme, following which it is intended that plc will be liquidated or dissolved. It is intended that, between the time of the Corp Scheme becoming effective and the listing of the New Shares, the New Notes and the Warrants, the plc Shares will be delisted from the Official List and cease trading on the London Stock Exchange's market for listed securities. Unless the context otherwise requires, this Part A assumes that the Schemes will be implemented in accordance with their terms and that the Group is the Corp Group. A.2 HISTORY OF THE MARCONI GROUP AND THE RESTRUCTURING EARLY HISTORY Corp, previously called the General Electric Company, p.l.c. ("GEC") and which is currently (but, on the implementation of the Corp Scheme, will cease to be) a wholly-owned subsidiary of plc, was incorporated as a private limited company in England in 1900 under the name The General Electric Company (1900) Limited and can trace its origins back to 1886. GEC originally operated in the electrical industry. The more significant events in the development of the Group are as follows: a. 1960s: significant expansion in the electrical industry through acquisitions b. 1970s and 1980s: acquisition of Videojet Systems International Inc. (data systems business), Picker International Holdings Inc. (medical systems business) and Gilbarco Inc. (commerce systems business); formation of GEC Plessey Telecommunications Holdings Limited ("GPT"), a 50 per cent. joint venture with The Plessey Company plc, subsequently increasing its stake to 60 per cent.; formation of two 50 per cent. joint ventures, GEC Alsthom N.V. with Alcatel S.A., and General Domestic Appliances Ltd (now known as General Domestic Appliances Holdings Ltd) with the General Electric Company of the United States; and c. 1990s: reduction of the stake in the GEC Alsthom joint venture to a 24 per cent. shareholding in Alstom S.A.; acquisition of the minority 40 per cent. stake in GPT and formation of Marconi Communications, combining the GPT business with the Marconi telecommunications operations in Italy, Hong Kong and South Africa under the same management structure. d. 1999: GEC separated the Marconi Electronic Systems business ("MES"), its international aerospace, naval shipbuilding, defence electronics and defence systems business, which merged with British Aerospace plc (now known as BAE SYSTEMS plc ("BAE")). GEC's remaining businesses were reorganised under plc, with GEC becoming a wholly-owned subsidiary of plc. Shareholders of GEC became shareholders in plc. MODERN HISTORY Following the separation of MES, the Group focused its strategy on communications technology and services. From 1999 through to 30 September 2002, the more significant events in the Group's history include: a. Year ended 31 March 2000: acquisition of RELTEC Corporation, FORE Systems, the business of RDC Communications Ltd, Nokia's transmission equipment business, the public networks business of Bosch, the Australian communications solutions business of Scitec and acquisition of 33

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- 27 per cent. of Atlantic Telecom (which was diluted in June 2000 to a 19.7 per cent. interest as a result of Atlantic Telecom's acquisition of First Telecom. Atlantic Telecom is now in liquidation); b. Year ended 31 March 2001: acquisition of Metapath Software International Inc. ("MSI"), Systems Management Specialist, Inc., Albany Partnership Limited and Mariposa Technology, Inc; c. Year ended 31 March 2002: acquisition of a 71.9 per cent. economic interest (49.9 per cent. of voting share capital) in Easynet Group plc ("Easynet") and disposal of its 92 per cent. interest in ipsaris Limited as part of the same transaction in July 2001; disposals of the remaining 24 per cent. interest in Alstom S.A. in February and June 2001, the remaining 1.49 per cent. interest in Lagardere SCA in September 2001, Marconi Medical Systems Group in October 2001, a 6.5 per cent. interest in Lottomatica SpA in November 2001 and February 2002, Marconi Commerce Systems Group in February 2002, the Marconi Optical Components business in exchange for a 9 per cent. interest in Bookham Technology p.l.c. in February 2002 (pursuant to a subsequent agreement between Bookham Technology p.l.c. and Nortel Networks Corporation, Corp now owns approximately 6 per cent. of Bookham Technology p.l.c.), Marconi Data Systems Group in February 2002 and the 50 per cent. interest in General Domestic Appliances Holdings Limited in March 2002; and d. Six months ended 30 September 2002: disposal of the Group's Applied Technologies division in July 2002 and the Group's strategic communications business (Mobile) in August 2002. RECENT DEVELOPMENTS On 19 December 2002, plc announced that Corp had reached agreement with RT Group plc (in members' voluntary liquidation) and its subsidiary RT Group Telecom Services Limited ("RTSL"), on a return of capital from Ultramast Limited ("Ultramast"), a joint venture set up in December 2000. The agreement provides for Corp and RTSL to waive all outstanding litigation relating to Ultramast. The Court approved this reduction of capital and accordingly RTSL has assumed full control of Ultramast. The Group has received approximately L41 million in cash, which includes approximately L19 million which was paid into Court by Corp pending the outcome of a lawsuit between the parties in August 2002. On 5 March 2003, plc announced that it had completed the disposal of two businesses from its Capital portfolio. The Group sold OTE SpA (its private mobile networks division, also known as TETRA) to Finmeccanica SpA for L2 million in cash, L4.8 million in assumed financial debt, and L8.2 million in assumed OTE debt to suppliers. Finmeccanica SpA has also agreed to release approximately L2.5 million to the Group from escrow relating to the August 2002 sale of Mobile (the Group's strategic communications business). On the same date, plc announced that it had completed the sale of Marconi Online to Coca Cola Amatil (N.Z.) Limited for NZ$2.95 million (over L1 million). On 26 March 2003, Corp and plc entered into a definitive agreement with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group. Under the terms of the settlement, which is conditional upon the Corp Scheme becoming effective, Corp will pay a total of L35 million to the ESOP Derivative Banks in full and final settlement of their ESOP related claims against the Group. This settlement amount will be paid from the fund of up to L170 million which was to have been set aside by Corp, as part of the Restructuring, pending resolution of potential liabilities of Group companies to Barclays Bank PLC, Salomon Brothers International Limited and UBS AG in relation to the Group's ESOP derivative arrangements. The settlement has made available approximately L135 million in cash which forms part of the L340 million comprising the cash element of the Corp Scheme Consideration. Without the ESOP settlement, the L135 million sum would not have formed part of the Corp Scheme Consideration. Further information relating to "Modern history" and "Recent developments" is set out in Appendix 5. BUSINESS REORGANISATION Following a profits warning announced on 4 July 2001, the Group undertook an operational review of its activities. The results of the operational review were announced in September 2001 and included a change of 34

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- management with the appointment of a new Chief Executive Officer and an interim Chairman. It also covered the Group's markets, its operations and scope of business and focused on adapting the Group to the changed circumstances of the telecommunications market during the substantial decline in market demand for the Group's products and services. As a consequence of the review, the Group streamlined its activities and disposed of a number of businesses during the period ended 30 September 2002 (as further described under "Modern history" above). For the purposes of financial reporting, with effect from 1 April 2002, the Group divided its continuing operations into two segments: Core and Capital. The Group divides its Core activities (for the purposes of financial reporting) into two main business types: Network Equipment, comprising Optical Networks, Broadband Routing and Switching ("BBRS"), European Access, North American Access, Outside Plant and Power ("OPP") and Other Network Equipment; and Network Services, comprising Installation, Commissioning and Maintenance ("IC&M") and Value Added Services ("VAS"). The Group's Capital activities comprise certain non-core businesses that the Group manages for value and ultimately for disposal. Activities in Capital include the Group's holding in Easynet Group Plc as well as a number of minor activities, assets and investments. Following the Restructuring, it is intended that the Group will segment its business along geographic lines and report its US Businesses separately from its businesses based in Europe and the rest of the world. The US Businesses will comprise the BBRS, OPP and North American Access Businesses and related Network Services activities. European and the rest of the world based businesses will comprise the Optical Networks, European Access, Other Network Equipment and the rest of the Network Services activities. BACKGROUND TO THE RESTRUCTURING The Group has faced difficult trading conditions for some time. The impact of a period of rapid and unprecedented deterioration in the global telecommunications market has been compounded for the Group by the costs of a number of acquisitions made since 1998. These acquisitions, which were primarily for cash consideration, resulted in a substantial part of the debt burden being carried by the Group and, in the light of reduced market demand for the Group's products and services, the trading and cash flow performances of the acquired businesses have been running at levels well below those that were anticipated at the time of acquisition. The Board of plc announced its intention, at its Annual General Meeting in July 2001, to initiate an operational review of the Group's business. The results of this review were announced in September 2001, along with the appointments of Michael Parton as Chief Executive Officer of plc, Derek Bonham as Interim Chairman of plc, Michael Donovan as Chief Operating Officer of plc as well as the management appointments of Neil Sutcliffe as chief executive officer of Marconi Capital and Geoffrey Doy as chief executive officer of sales and marketing of plc. Against a background of further market deterioration early in 2002, plc announced on 22 March 2002 that Corp and plc had decided not to enter into new banking facilities to refinance Corp's then existing syndicated bank facilities. Following this decision, Corp and plc agreed to cancel the undrawn commitments under the existing facilities and agreed that the drawn portion under the Bank Facility (which was due for repayment on 25 March 2003) would be repayable on demand. Following the decision not to refinance the then existing syndicated bank facilities the Business Plan was prepared. This Business Plan was presented to the Co-ordination Committee and the Informal Committee of Bondholders and was used by Corp and plc as a basis for formulating the Heads of Terms for the Restructuring. The Business Plan assumed that recovery in the Group's markets would not commence until the end of the calendar year 2003. A set of sensitivities were applied to reflect the scenario of more difficult market conditions, and in particular a delay in market recovery beyond the end of 2003. Given continuing uncertainty in market conditions, further revisions have been made to the Business Plan. In proposing the Restructuring, Corp and plc have assessed the proposed capital structure of Corp against the scenario of a delay in market recovery and are confident that the proposed capital structure of Corp is appropriate in circumstances where such a delay occurs. However, the Group cannot predict with any level of certainty the occurrence, timing or extent of any market recovery. 35

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- On 29 August 2002, plc announced that Corp and plc had concluded Heads of Terms with the Co-ordination Committee and the Informal Committee of Bondholders for the financial restructuring of the Group. On 13 September 2002, the Group announced that, in accordance with the Heads of Terms, interim security over the balance of the Lockbox Accounts established in April 2002 had been granted in favour of the Bank Creditors, the Secured Bondholders and Barclays Bank PLC (as the only ESOP Derivative Bank which committed to support the Restructuring prior to 15 October 2002). On 16 December 2002, the Group announced amendments to the terms of that interim security. Further details are set out in Parts D.1 and D.2. On 16 December 2002, plc also announced modifications to the Heads of Terms by way of an addendum. On 7 February 2003, plc announced that Corp and plc had reached agreement in principle with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group. On 18 March 2003 plc announced that documentation in relation to the proposed Restructuring had been filed with the Court and provided an update on certain aspects of the proposed Restructuring. On 26 March 2003 and 24 March 2003 respectively the required consents were received to certain pre-completion steps for the Restructuring from the requisite majorities of the Syndicate Banks and the members of the Informal Committee of Bondholders. Corp and plc do not currently anticipate that the Corp Group's day to day operations, in particular supplies to customers and the payment of suppliers and employees, will be significantly affected by the proposed capital structure of Corp following the Restructuring. Further information relating to the Restructuring is set out in Part C of this Section and a discussion of the risk factors arising from implementation of the Restructuring is set out in Part F.2 of this Section. RESTRUCTURING Taking into account the cash to be distributed as part of the Restructuring and approximately L40 million of subsidiary-level bilateral loans and finance leases, the net indebtedness of the Corp Group immediately following the Corp Scheme becoming effective is expected to be approximately L117 million. The Corp Group is expected to retain approximately L602 million of cash immediately following the Corp Scheme becoming effective, of which approximately L167 million is expected to be restricted cash (see Part D.4 of this Section for further information about retained cash). These estimates assume that the Corp Scheme becomes effective on or around 19 May 2003 and that there is no increase in the cash element of the Corp Scheme Consideration (and consequential decrease in the amount of Junior Notes issued) as a result of any asset disposal prior to 1 May 2003. Assuming the Corp Scheme is implemented in accordance with its terms, Corp Scheme Creditors will receive in aggregate: a. CASH: L340 million cash; b. NEW SENIOR NOTES: the euro equivalent (calculated at the Currency Rate) of L450 million in aggregate principal amount of new guaranteed senior secured notes due April 2008 to be issued by Corp denominated in euro and/or US dollars, subject to elections made in Claim Forms and Account Holder Letters, with interest payable quarterly in cash at a rate of 8 per cent. per annum; c. NEW JUNIOR NOTES: the sum of US$300 million plus the US dollar equivalent (calculated at the Currency Rate) of L117.27 million in aggregate principal amount of new guaranteed junior secured notes due October 2008 to be issued by Corp denominated in US dollars with interest payable quarterly in cash at a rate of 10 per cent. per annum or, at Corp's option, in kind (by issuing additional New Junior Notes) at a rate of 12 per cent. per annum; and d. NEW SHARES: 995,000,000 ordinary shares, representing 99.5 per cent. of the issued ordinary share capital of Corp immediately following the implementation of the Restructuring. The cash element of the distribution will be increased by the net proceeds of any asset disposals, other than L82 million of excluded asset disposal proceeds, received on or after 1 December 2002 and before 1 May 2003, and the aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of the sterling amount 36

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- by which the cash element is increased (such calculation to reduce the L117.27 million figure referred to in c. above). The New Notes may be redeemed at Corp's option in whole, but not in part, at any time at a redemption price equal to the greater of (i) 110 per cent. of their principal amount, and (ii) a make-whole amount equal to the sum of the present values of remaining scheduled payments of principal and interest, using a discount rate that is 50 basis points above the yield on US treasuries of similar maturity to the New Senior Notes and New Junior Notes, as applicable, plus, in each case, accrued interest. Under the terms of the New Notes, Net Proceeds of non-exempt asset disposals must be applied to redeem first the New Junior Notes and then, under certain circumstances, the New Senior Notes. For further information, see Part C.3 of this Section and Appendix 8. In order to support the Group's working capital requirements following the Restructuring, Corp and Marconi Bonding Limited have entered into the Performance Bonding Facility (a L50 million committed performance bonding facility provided by HSBC Bank plc and JPMorgan Chase Bank) and Marconi Communications, Inc. has entered into the Working Capital Facility (a US$22.5 million revolving facility provided by Liberty Funding L.L.C.). The Performance Bonding Facility is conditional on the Corp Scheme becoming effective. A brief description of the terms and conditions of the Performance Bonding Facility and the Working Capital Facility is set out in Part D.4 of this Section. Certain risks associated with working capital are set out in Part F of this Section. The Corp Scheme is not conditional upon the plc Scheme becoming effective and Corp is satisfied that it will be able to implement the Corp Scheme whether or not the plc Scheme becomes effective. Corp is satisfied that, if the Corp Scheme is implemented, the Corp Group will be sufficiently ringfenced from plc that the Corp Group will be able to operate effectively, even if plc has been forced to commence an insolvency proceeding. RINGFENCING OF US ASSETS As part of the Restructuring, it is proposed that Corp's US Businesses, namely the North American Access Business, BBRS Business and OPP Business, be contractually separated or ringfenced from the rest of the Group (the "US RINGFENCING"). Specific details of the US Ringfencing include: a. Marconi Communications, Inc. and its subsidiaries which contain the North American Access Business, BBRS Business and OPP Business will constitute the Ringfenced Entities that are contractually separated from the Non-Ringfenced Entities. While the business units involved are located predominantly in the United States, the Ringfenced Entities will not be limited to subsidiaries that are organised or incorporated under the laws of the United States, the states thereof or the District of Columbia and will also include subsidiaries owned by Marconi Communications, Inc. that are organised and incorporated under the laws of other jurisdictions including Ireland, Mexico and Switzerland; b. the covenants in the indentures governing the New Notes will significantly restrict the type of financial, operational and other dealings that the Non-Ringfenced Entities can have with the Ringfenced Entities. The covenants in the New Notes will also require Corp to separate the North American Access Business, BBRS Business and OPP Business into separate subsidiaries (or groups of subsidiaries) within the US Ringfencing no later than the second anniversary of the issue date of the New Notes. Moreover, the Non-Ringfenced Entities will generally be prohibited from providing funding for any of the Ringfenced Entities and, following the separation of the three principal businesses within the US Ringfencing, the North American Access Business, BBRS Business and OPP Business will generally be prohibited from providing funding to each other; c. the Ringfenced Entities will enter into various agreements with the Non-Ringfenced Entities necessary to ensure that from the Effective Date those dealings that are permitted with each other will be provided in the ordinary course of business on an arm's length basis or otherwise as required or permitted by the covenants in the indentures governing the New Notes. A discussion of risk factors associated with the US Ringfencing is set out in Part F of this Section. 37

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- A.3 MARKET ENVIRONMENT AND BUSINESS STRATEGY MARKET ENVIRONMENT The late 1990s saw unprecedented growth in capital expenditure on telecommunications equipment as established and new operators invested in increased capacity to meet expected growth in both data and mobile traffic. Although data and mobile traffic has grown it has not grown as strongly as expected and operators' turnover has not matched the investment in capacity; both new and incumbent carriers have become overextended financially and capital spending has been dramatically curtailed. In this environment, telecommunications equipment vendors, like the Group, have experienced substantial declines in turnover. The speed of this decline has been far greater than anticipated and, in this environment, the Group, along with its major competitors, has been unable to reduce the cost base of the business at the same rate and consequently has experienced a significant decline in business performance. Corp and plc consider that the slowdown in network equipment sales has been driven primarily by oversupply rather than reduced demand in the end-user telecommunications services markets. Underlying data and mobile traffic growth, driven by broadband, data and mobile services, remains quite strong and, as this absorbs installed over-capacity, Corp and plc believe carriers will invest in additional infrastructure. BUSINESS STRATEGY As a provider of networking technology and services that enables telecommunications operators to evolve narrowband networks to next generation broadband and mobile networks, the Group is now focusing its strategy around: a. nurturing pre-existing relationships with its customers in current generation technologies (for example Synchronous Digital Hierarchy ("SDH") and then evolving these customer networks over time to the next generation Dense Wavelength Division Multiplexing ("DWDM") optical networks); b. development and effective marketing of genuine "best in class" solutions; and c. developing and enhancing the services offered to existing and new customers. The Group has taken extensive action to reduce the scope of its activities and to rationalise or curtail non-core areas. The Group's near-term objective is to restore its Core businesses to operating profitability (before goodwill, amortisation and exceptional items) and generate positive operating cashflow (before exceptional cash costs). In the longer term, the Group aims to develop and expand its product portfolio and markets on a basis that is consistent with its business strategy. The Group considers that partnerships, where research and development and routes to the market are shared for mutual benefit, will be an increasingly important factor in the industry and expects the Group to be an active participant in such partnerships. Business positioning Development of the Optical Networks business is a strategic priority for the Group. The Group's objective is to maintain a leading position in the European optical networking markets and to build market share in Central and Latin America as well as the Asia Pacific region. Development of the Network Services businesses is the Group's other key strategic objective with the aim of increasing its turnover derived from such services activities. The Group is also seeking to increase market share in selected product and geographic markets where it has strong customer relationships. Accordingly, the Group will deploy resources in developing its portfolio of fixed wireless transmission and access products as well as its Access Hub multi-service access node. The Group believes that it has a number of developing or newly developed products which are potentially "best in class" where it has yet to penetrate major new telecommunications company customers. In particular, the 38

EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- Group is focused on developing the North American market for its leading-edge range of multi-service switches and the UK market for its unique class 5 Softswitch solution. The Group's OPP and North American Access Businesses are being managed for value and ultimately for disposal. The proceeds of these disposals will be used to repay part of the New Junior Notes. The North American Access Business may be sold prior to 1 May 2003, in which event the net proceeds of the disposal will be applied to increase the cash element of the Corp Scheme Consideration (and the aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of that amount). Organisational efficiency and effectiveness Since September 2001, the Group has embarked on a sequence of substantial cost reduction programmes to reduce sales and marketing, general and administrative and research and development overheads. These programmes remain in place and continue to deliver cost reductions. Organisationally, extensive rationalisation will continue to be an important part of the Group's strategy in order to reduce costs in all areas of production and overhead. In particular, the supply chain will continue to be restructured to remove excess capacity and reduce break-even points. As part of this strategy, the Group will retain control of functions only where it possesses key competencies. Other functions, such as the manufacturing of non-complex products, will continue to be outsourced and the supply chain cost base will be rationalised to a level more in line with expected sales volumes. A.4 GROUP'S PRINCIPAL ACTIVITIES plc is the holding company of the Group, and was incorporated as a public limited company in England in 1999. It conducts its commercial activities primarily through Corp and Corp's subsidiaries. Both Corp and plc are subject to the requirements of the Act and the Companies Act 1989. The Group is headquartered in London with principal operating sites in Coventry, Beeston, Chorley, Camberley, Liverpool, London, Stafford and Wellingborough (UK); Florida, Pennsylvania, Ontario, Georgia, Mississippi, North Carolina, Illinois, Texas and Montreal (US and Canada); Genoa, Marcianise and Pisa (Italy); Backnang, Offenburg, Frankfurt and Radeberg (Germany); Madrid (Spain); Melbourne and Sydney (Australia); Beijing, Guilin and Hong Kong (China); Darulam and Kuala Lumpur (Malaysia); Auckland (New Zealand); New Delhi (India); Riyadh (Saudi Arabia); Dubai (United Arab Emirates); Springs (South Africa); Sao Paulo and Votorantim (Brazil); and Naucalpan de Juarez and Huixquilucan Edo de Mexico (Mexico). For the purposes of financial reporting, with effect from 31 March 2002, the Group divides its continuing operations into two segments: Core and Capital. CORE BUSINESSES For the purposes of financial reporting, the Group divides its Core activities into two main business types: Network Equipment, comprising Optical Networks, BBRS, European Access, North American Access, OPP and other Network Equipment; and Network Services, comprising IC&M and VAS. The Group's customer base includes telecommunications companies and providers of internet services for their public networks, and certain large corporations, government departments and agencies, utilities and educational institutions for their private networks. Sales, marketing and distribution The Group sells its network equipment and network services using its direct sales force as well as indirect channels such as local partners and distribution partners. The Group's sales activities include sales and marketing organisations in all major geographic regions. There are specialised product marketing groups which support these organisations internally and a central marketing staff which provides strategic direction and customer and market communications support for these organisations externally. Each of these regional organisations has responsibility for account management, sales, technical support and contract negotiation. 39

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- The Group's distribution partners include Ericsson, Italtel, Nokia and Siemens. A seven-year agreement with Ericsson was signed in July 1999 that allows Ericsson to market the full range of the Group's SDH equipment throughout the world. In June 2002, the Group announced an additional seven-year agreement enabling Ericsson to source its range of next-generation DWDM optical networking equipment as well as encompassing the existing 1999 agreement on SDH equipment. The Group also entered into a five-year agreement with Nokia in November 1999 to market the Group's SDH and DWDM systems. Customers The Group benefits from the continued support of its strong customer base which comprises mainly well-established incumbent telecommunications operators and government agencies. The main customers of the Group's network equipment and services include BT, the Metro City Carriers in Germany, Telecom Italia, the UK Government and Vodafone Group in Europe; BellSouth, Qwest, SBC, the US Federal Government and Verizon in the United States; China Railcom, China Telecom, China Unicom, Telkom Malaysia and Telstra in the Asia-Pacific region; and Brasil Telecom, Telecentro Oeste, Telcel, Telefonica and Telmex in Central and Latin America. These customers accounted for 51 per cent. of the turnover of the Core businesses during the six months ended 30 September 2002. Customers of the Group's Optical Networks and European Access Businesses are predominantly based in Europe as well as in Asia-Pacific and Central and Latin America. Customers of the Group's BBRS, OPP and North American Access Businesses products and services are predominantly based in the Americas. In addition, the Group provides network services to a number of customers in the transportation and utility sectors, mainly in Europe. Except for BT, each of the Group's customers accounted for less than 5 per cent. of the Group's total turnover and Core turnover for the financial year ended 31 March 2002. For the same period, BT accounted for approximately 9 per cent. of the Group's total turnover and 14 per cent. of the turnover of its Core businesses. During the six months ended 30 September 2002, BT accounted for 15 per cent. of the Group's total turnover and 17 per cent. of the turnover of its Core business. A discussion of certain risks associated with the Group's reliance on a relatively small number of customers is set out in Part F of this Section. The Group has entered into frame contracts with most of its major customers. While the terms of the frame contracts vary from customer to customer, such contracts generally set out the terms and conditions (including pricing) on which the Group will supply a customer with products and services. The length of frame contracts varies from customer to customer and can range from 12 months to five years. Some of the frame contracts establish price and volume expectations which provide the Group with some visibility of expected sales during the terms of the contracts. However the frame contracts do not typically guarantee the volume or value of products or services actually supplied by the Group, which remain at the discretion of the relevant customer. Near the end of their term, some frame contracts impose an obligation on the parties to negotiate in good faith to agree an extension of the contract. In some cases, frame contracts contain change of control clauses which may give rise to a termination right as a result of the Restructuring. In any event, customers are not normally contractually bound under their frame contracts to purchase products or services solely from the Group. Customers also often have the right to terminate a frame contract after a specified notice period. Notwithstanding the flexibility customers have in terms of the volume and value of the orders they place and whether they place those orders with the Group or one of its competitors, customers will often have a commercial incentive to continue to purchase all of their requirements for certain types of products and services from (and to have those parts of their networks serviced by) the Group. A discussion of certain risks associated with termination rights triggered as a result of the Restructuring is set out in Part F of this Section. NETWORK EQUIPMENT The Group designs and supplies communications systems that transmit and switch voice, data and video traffic predominantly in public networks. The Group's Network Equipment products include optical networking 40

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- systems, broadband and narrowband switches, routers and aggregation devices, wireless transmission systems and software management systems. In addition, the Group sells outside plant and power products for use in communications networks. Aggregate sales for the Group's Network Equipment businesses for the financial year ended 31 March 2002 were L1,804 million (39.5 per cent. of total Group sales) compared to L3,359 million (48.4 per cent. of total Group sales) in the year ended 31 March 2001 and L2,583 million (45.1 per cent. of total Group sales) in the year ended 31 March 2000. Aggregate sales for the Group's Network Equipment businesses for the six months ended 30 September 2002 were L600 million (54.2 per cent. of total Group sales). Overview of the public network market Historically, government-owned or government-regulated monopolies have operated public networks, which traditionally transmitted voice calls between users. Privatisation and deregulation of public networks contributed to the entry of a large number of new companies into the public network market, offering new voice, data and video services. The public network markets in which the Group operates are highly competitive. The Group's principal competitors include Alcatel, Cisco Systems, Ericsson, Fujitsu, Lucent Technologies, Nortel Networks and Siemens. The primary method of competition in the public network market is the widespread use of open bids for equipment purchases. Buyers use a combination of factors to evaluate bids, including price, technical compliance, ability to deliver in the required timescale and provide after-sales support, financial stability and long-term viability. A number of competitors have substantial technological and financial resources (including research and development resources) and operate in all significant market segments of the industry. As the public network and private network markets converge, other specialist companies in the information technology sector may also emerge as strong competitors. In addition, competitors may emerge in rapidly developing telecommunications markets such as China. A description of risk factors relating to the Group's ability to remain competitive through R&D investment is set out in Part F of this section. A typical public network can be portrayed as comprising three high level layers. These are the service, switching and transport layers. Traffic in the network is moved around the network by equipment in the transport layer and routed to different points in the network by equipment in the switching layer. Equipment in the services layer defines and makes available the service associated with each particular class of network traffic, for example voice, data or video services. Public networks, which comprise the three layers above, can typically be either access, metro or core networks, depending on the connections they establish. The access network typically connects an end user of a service to a network operator's local exchange (where switches are located). The core network usually connects an operator's major points of presence, for example, the routes between two cities. The metro network typically provides connections between the access and core networks - for example, between a major city and the various local exchanges or points of presence within a particular geographic region. The Group's equipment can be found in most parts of the typical public network with its optical products predominantly operating in the transport layer, its multi-service switches and Softswitch in the switching layer and its range of access products found in most layers of the access network. Optical Networks Communications service providers primarily use three technology standards, SDH, SONET and DWDM, to transmit voice, data and video traffic over fibre optic communications networks. DWDM is a relatively new transmission standard that is used worldwide. SDH is the digital transmission standard that is used in most regions except North America and Japan, where SONET is the predominant standard that is used. In June 2002, the Group announced that it was ceasing development of its SONET products because of continuing weak market conditions. The Group has not made material sales of SONET products. The Group's Optical Networks products contributed 16.1 per cent. of total Group sales in the year ended 31 March 2002 and 21.9 per cent. in the six months ended 30 September 2002. During the latter period, sales were predominantly in Europe and Asia, with the remainder from the Americas. 41

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- The Group has focused its development on a comprehensive range of optical transmission equipment based on SDH and, more recently, DWDM. A discussion of the risks associated with the telecommunications market is set out in Part F of this Section. a. Synchronous Digital Hierarchy: The Group was a pioneer of SDH technology following its introduction in the early 1990s, and has continued to introduce next generation SDH products. The Group is a leading supplier of SDH transmission equipment within Europe and has a tenable position in other markets including the Asia-Pacific market. SDH contributed approximately 85 per cent. of the Optical Networks Business's sales in the year ended 31 March 2002 and approximately 80 per cent. in the six months ended 30 September 2002. The Group's add-drop multiplexers transport voice, data and video traffic streams over ring-based optical fibre networks to provide protection against network failures. The Group's line systems transport high-capacity voice, data and video traffic streams between major traffic centres. The Group also supplies cross-connects to provide points of flexibility and restoration within an SDH network and to switch traffic streams from one transmission line to another. Over the next twelve months, the Group intends to launch a number of more cost effective next generation SDH products with greater functionality, for use both in core networks and for connecting residential and business customers to the core network, such as its SMA Series 4 range of add-drop multiplexers and the MSH range of cross-connects announced in September 2002. b. Dense Wavelength-Division Multiplexing: DWDM is the transmission of closely spaced signals through a single optical fibre using wavelengths, each of which functions as a separate, independent signal, and allows the capacity of installed optical fibre to be increased substantially to meet future growth in demand for voice, data and video traffic capacity. The Group's DWDM equipment is complementary to the Group's SDH equipment and enables service providers to increase significantly the bandwidth of installed fibre optic cabling and still use the existing network infrastructure. Over the past few years, the Group's share of the next generation DWDM market in Europe has grown significantly. The Group has already established a tenable market position with its photonic line system ("PLx"). The Group has recently launched a soliton-based, ultra-long-haul photonic line system ("UPLx") that extends the distance that traffic can be transported before regeneration of the signal is required. The Group is developing this product specifically for ultra and extended long-haul DWDM networks which will have much higher per fibre capacity than SDH or SONET networks. The Group has announced its first order for this product in Australia. In 2000 the Group launched a remotely re-configurable photonic add-drop multiplexer ("PMA"). This product allows traffic streams to be inserted and removed from a transmission ring without disturbing other traffic streams. The Group has also developed a range of point-to-point and ring-based Metro products ("PMM"). DWDM contributed approximately 15 per cent. of the Optical Networks Business's sales in the year ended 31 March 2002, and approximately 15 per cent. in the six months ended 30 September 2002. The Group's DWDM equipment is complementary to the Group's SDH equipment and the Group intends to take advantage of its positions in the SDH markets of Europe, Central and Latin America and Asia Pacific to sell its DWDM products to its existing SDH customer base as well as to new customers wishing to make a cost effective and simple increase in their available bandwidth. The Group's transmission equipment is managed by its network management system (ServiceOn). ServiceOn provides a broad range of management functions required by a network operator. It can be used by service providers to remotely re-configure their networks in accordance with changing traffic patterns. ServiceOn also provides network performance information and has fault detection capability to support the day-to-day operation of the network. The Group's broad portfolio of Optical Networks products, coupled with scalability and ease of upgrade, enables it to sell optical networks to its customers which optimise network design and cost for those customers. The Group's focus on overall optical networks solutions, rather than single product solutions, enables it to design 42

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- more cost effective networks and to integrate future product offerings over the life of frame contracts. The Group believes that its installed base of SDH equipment, deep customer relationships, superior knowledge of the incumbent network design, and interoperability of its products with that installed base of SDH equipment, are an important competitive advantage for both the existing and new SDH and DWDM product ranges. The Group's objective is to maintain a leading position in the European optical networking markets and to build market share in the Asia Pacific region as well as Central and Latin America. Broadband Routing and Switching In 2001, the Group refocused its technical and commercial resources in the BBRS Business towards customers requiring more resilient networking platforms of the sort found in carrier class networks, namely government and military agencies, selected telecommunications service providers and other large corporations. BBRS also continues to provide support services to its approximately 1,000 US Federal Government service provider and enterprise customers. The Group's single largest customer of BBRS products is the US Federal Government with whom the Group has enjoyed a long relationship. To date, this has resulted in an installed base of BBRS products in US Federal Government communications networks of approximately US$1.3 billion in value. The BBRS Business contributed 4.6 per cent. to the Group's sales in the year ended 31 March 2002 and 6.6 per cent. in the six months ended 30 September 2002. The BBRS Business' sales are made predominantly in the North American market and these sales accounted for 4.3 per cent. of total Group sales in the latter period. The Group's products address the three principal packet-oriented protocols in use today: asynchronous transfer mode ("ATM"); internet protocol ("IP"), and multi-protocol label switching ("MPLS"), an emerging standard which provides greater predictability, Quality of Service ("QoS") and differentiated service levels for IP-based data, voice and video communications when compared with services available over traditional, connectionless IP networks. The Group's principal products comprise a range of multi-service switch-router devices that both establish the physical communication links between end points, as well as determine the optimal route across the network. In addition, the Group also develops and sells a range of integrated access devices ("IADs") which are cost-effective solutions supporting converged voice, data and video transmissions over a single circuit. The Group has focused on the sale and support of its ASX-200BX, ASX-1000 and ASX-4000 range of multi-service switches, while continuing the development of its recently-launched next generation BXR-48000, which the Group believes provides the highest capacity of any multi-service switch currently available in the telecommunications industry. The Group's switch-router product platforms, such as the ASX-4000 and BXR-48000 are designed to support communications traffic transmitted by ATM, IP and MPLS protocols. They are designed to enable operators to build on their existing switching and routing infrastructure to continue to support their legacy services while offering the flexibility and scalability to roll-out next generation IP, wireless and packet voice services. They are also designed to enable operators to reduce their capital investment and operating costs. The ASX-4000 can switch at transmission speeds ranging from 10 to 40 gigabits per second ("Gbps") and can be positioned either within the core, or at the edge, of service provider networks or high-capacity private networks. Recent developments of the ASX-4000 switch include applications to allow service providers to transport voice traffic over packet switched infrastructures such as ATM ("VoA") or IP ("VoIP"). The BXR-48000 can operate at transmission speeds ranging from 40 Gbps to 480 Gbps. It can be configured as a very high capacity router or a very high capacity switch. Routers function in the IP ("packet") networking domain, while switches typically operate in the traditional voice, Frame Relay and ATM domains. In March 2002, following technical trials on the first BXR-48000 unit, the US Department of Defense's Naval Research Laboratory ("NRL") demonstrated the high performance, high security, speed, reliability and functionality of this product and subsequently, in September 2002, the US Department of Defense placed a firm order for the product. The military-grade capabilities demonstrated by the BXR-48000 are equally applicable for the voice, video, data and multiservice networks of service providers and large non-military institutions. In December 2002, the Group announced a further sale of the BXR-48000 to a leading European financial institution. 43

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- The Group also provides support services to customers of its BBRS products. The Group reports these revenues within its Network Services segment. The BBRS Business service offerings range from routine technical support and assistance for its switch-routers, to dedicated, on-site project and programme support for complex network environments. Within the broadband switching and routing market, the Group believes that the IP router market will be a significant source of potential growth in the longer term due to the continued growth in IP traffic and the launch of new services such as VoIP. It should be noted, however, that the introduction of these new services is dependent on the development of technologies that permit the "toll-grade" transmission, over IP, of voice and real-time multimedia services. In the meantime, concern from carriers and security sensitive private network operators over the security and reliability of their networks are expected to lead to continued growth in the ATM market. Consequently, the Group intends to continue to focus its research and development on the further development of its multi-service products which support ATM, IP and MPLS protocols. In particular, the Group's BBRS equipment is designed to enable carrier operators to address the divergent demands of today's difficult market environment. The market demands continued support for the ATM networks that transport today's services as well as providing a safe and viable migration path for the convergence of these networks with data oriented IP networks. The BXR-48000 is a key strategic platform through which the Group aims to deploy further its range of BBRS products into the networks of large telecommunications providers. As part of the Restructuring, it is proposed that the BBRS Business be contractually separated or ringfenced from the rest of the Group. European Access Access equipment connects the end user to a service provider's switch or local exchange across what has been traditionally known as the "last mile" or "local loop". This is the physical wire, fibre or wireless link that runs from a subscriber's telephone set or other communications device to the service provider's local exchange. The Group designs, manufactures, sells and supports a range of access equipment which maximises the capabilities of physical transport media, including copper telephone lines, fibre optics, and both licensed and unlicensed wireless spectra. The Group's access systems activities have undergone significant rationalisation and are now focused on leveraging the Group's reputation and relationships in Europe to continue penetration of key customers with fixed wireless, Access Hub and voice software systems. The European Access Business contributed 8.4 per cent. of total Group sales in the year ended 31 March 2002 and 11.6 per cent. in the six months ended 30 September 2002. During the latter period, approximately 85 per cent. of the European Access Business sales were in Europe, 12 per cent. in Asia Pacific, with the remainder in Central and Latin America. The principal access systems products are: a. Digital Subscriber Line Access Multiplexers ("DSLAMs"): These products are typically located within an operator's local exchange on one end of the subscriber loop providing broadband internet/DSL data services. The Group's Access Hub, which can be configured as an advanced high density DSLAM also incorporates integrated ATM edge switching and IP multi-casting functionality, enabling it to perform as a broadband aggregator for multiple applications including voice, video and data services as well as providing conventional DSLAM functionality, such as asymmetric digital subscriber line (ADSL) capabilities. This next generation product offers one of the highest port densities available in the industry and is optimised for ease of configuration and management. The Group launched its Access Hub platform in 2001 and has already won two major frame contracts with Telecom Italia and Telkom (South Africa). Other customers include Wind (Italy). b. Fixed Wireless: The Group's Skyband MDRS product family encompasses the Group's point-to-point ("PtP") portfolio which offers long and short haul SDH transmission for services ranging from trunk networking, local access bypass and mobile network feeder applications. The Group's Skyband MDMS point-to-multi-point ("PtMP") portfolio offers cost-effective broadband wireless solutions ranging from 2.4 Ghz to 32 Ghz, depending on the country's frequency 44

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- allocation, and supports subscriber voice and broadband data, using both standards-based and optimised techniques. The Group's radio planning and installation services enhance the Group's ability to offer customised, cost-effective solutions for network operators and service providers. The main customers of the Group's range of fixed wireless access products include mmO(2) (Germany), and E-plus (Germany). c. Voice Systems: The Group provides switching hardware and software to telecommunications and media carriers in both legacy narrowband and next generation networks. The three main activities are: (i) Narrowband Switch Support: The Group continues to supply upgrades and extensions to its significant installed base of narrowband voice telephony systems (System X). The majority of this installed base is in the UK. Upgrades and extensions have been driven by the need for operators to adapt their networks to changing traffic patterns, predominantly caused by the growth in Internet traffic. (ii) Softswitch: This next generation product is a system which builds on many of the features of the narrowband switch allowing network operators to combine their traditional telephony services with broadband multimedia and high-speed data services across a single broadband packet switched network. The Group's Softswitch is currently one of only a limited number of products, offering full class 5 capability available in the market. It can therefore address both public and private network applications and has been designed to allow customers significantly to reduce the cost of operating their networks. The Group's Softswitch has been installed in the Dubai Marina project where it is currently delivering voice and multimedia services and is undergoing trials with a number of customers in the United Kingdom. In December 2002, the Group announced the sale of its Softswitch system to support Jersey Telecom's roll out of a suite of commercial and residential broadband services. (iii) Intelligent Networks: As legacy narrowband services have evolved, operators have experienced an increasing need to provide additional value added services that can be billed to individual subscribers. Corp and plc believe that the Group's Intelligent Networks products are amongst the leading products in the UK market in the provision of hardware and software for fixed networks that allows carriers to offer a range of enhanced voice services, beyond those contained in existing narrowband switching products. These services, such as 0800 numbers, voicemail, call waiting and ringback, can be controlled from a small number of service points where data and applications can be stored and updated centrally. Intelligent Network products also work with switches from other manufacturers, increasing their attractiveness to operators whose systems contain a range of products. The services offered by these products provide differentiating capability for the Group's customers. The Group therefore undertakes directly customer funded developments as well as Group-funded research and development. The Voice Systems activities' primary geographical market is the UK where the Group has a strong position in the UK circuit switching market, and the Group is an equipment supplier to customers such as BT, Cable and Wireless, NTL and Telewest, each of whom relies on the Group for upgrades and care and maintenance of installed equipment. The Group's narrowband switching products are deployed in approximately 70 per cent. of BT's local telephone exchanges and are central to the UK public service telephone network ("PSTN"). The Group's initial market entry for its new Softswitch product is seen as the confluence of the growth in IP Voice, IP managed VPN, and the growth of DSL. This creates an opportunity to develop a new range of cost-effective services for corporations, by extending the reach of their private networks to smaller locations and, through DSL connectivity, uniquely to home workers. Initially, establishing the Softswitch as a major supplier in this sector will provide the foundation for further expansion into small to medium sized enterprises and then pure residential services (as opposed to corporate home worker). 45

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- d. Other Access Products: The Group has a range of other access products that are deployed in its customers' networks, including its Deep Fiber DMP product. This product brings the high bandwidth of the core fibre network into the access network. North American Access The Group designs, sells and supports a range of copper and fibre based access platforms for markets that use North American communications standards. The Group's largest customers are BellSouth and Sprint and the Group is one of the main suppliers of digital loop carrier systems by market share in North America. The North American Access Business contributed approximately 5 per cent. of total Group sales in the six months ended 30 September 2002. The Dutch Link Control (DLC) DISC*S(R) family of products provide copper based access for voice and data services. The Group has provided over ten million lines of digital local loop equipment based on the DISC*S(R) platform throughout the United States, and has recently introduced a smaller footprint broadband high density version of the platform. The Group's fibre to the curb solutions support a mix of voice, broadband data and video services to each customer. They deploy fibre all the way to a curbside pedestal and utilise copper or coax cables only for the short final drop to the customer's premises. As part of Restructuring, it is proposed that the North American Access Business be contractually separated or ringfenced from the rest of the Group. The North American Access Business has undergone significant rationalisation and is being managed for value and ultimately for disposal. The proceeds of this disposal will be used to repay part of the New Junior Notes. The North American Access Business may be sold prior to 1 May 2003, in which event the net proceeds of the disposal will be applied to increase the cash element of the Corp Scheme Consideration (and the aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of that amount). Outside Plant and Power The Group is one of the major providers of OPP products and services in North America. The Group is one of the major suppliers to Qwest, Verizon, BellSouth, SBC, Sprint, AT&T and WorldCom. In addition, the Group is a supplier to AT&T, Verizon, Cingular, Telcel and US Cellular. The Group currently has contracts to provide services to Bechtel in the building of wireless networks for AT&T and Cingular. The OPP Business contributed 5.4 per cent. of total Group sales in the year ended 31 March 2002, and 7.2 per cent. in the six months ended 30 September 2002. The OPP Business has three primary product lines: a. Outside Plant supplies connection, protection and enclosure products for the local loop, and is a supplier in enclosure design such as thermal management and analysis, water and dust intrusion, equipment packaging techniques and corrosion resistance. Although these are primarily passive hardware products, the trend of placing sensitive electronics outside the local exchange and closer to the subscriber requires increasingly sophisticated enclosures and static protection. The connection and protection products include distribution pedestals, building entrance terminals, cross connect terminals, cable television enclosure products, fibre optic splice enclosures, large electronic configuration cabinets, central office main distribution frames, heat management systems, power surge protection devices and connection blocks and terminals. The enclosure products are metal and plastic cabinets that house equipment such as power supplies, connection products, and digital and wireless transmission equipment. b. Power supplies power systems to service providers and telecommunications equipment manufacturers for the local loop, local exchange switching, wireless sites and other customer equipment such as computer networks. The Group's power products and systems include large power systems for local exchange applications, smaller cabinet power systems with "plug and play" flexibility, modular power systems, custom power subsystems sold to OEMs, DC distribution 46

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- and DC-DC conversion systems and traditional ringing and signalling equipment. The Group's family of power products is marketed under Vortex(R), Lorain(R) and other brand names and is based on a single integrated platform suitable for multiple wireline and wireless applications. This microprocessor-based "plug and play" architecture allows for software-based configuration, management, monitoring and local and remote power system access that is easily expanded for system configuration and control. c. Services provides customers with software that allows for remote monitoring and control of power systems as well as complete programme management support for communications systems deployment. Additionally, the Group provides a range of customer services, including site contract maintenance and breakdown service, spare parts provisioning, equipment depot repair, and training. The OPP Business' principal geographic markets are in North America and Central and Latin America. As part of the Restructuring, it is proposed that the OPP Business be contractually separated or ringfenced from the rest of the Group. OPP is being managed for value and ultimately for disposal. The proceeds of this disposal will be used to repay part of the New Junior Notes. Other Network Equipment businesses Other Network Equipment businesses contributed 2.6 per cent. of total Group sales in the year ended 31 March 2002, and 2.6 per cent. in the six months ended 30 September 2002. These comprise mainly the following businesses: a. Marconi Interactive Systems ("MIS"): MIS manufactures payphones and multimedia terminals which range from an indoor "desk top" phone through to sophisticated street multimedia terminals which have voice telephony and internet access capability. The business is predominantly UK-based and sells primarily to the major public network customers such as BT, Telecom Italia, Singtel, Telenor, Teledanmark and, through Loxley Business Information Technology Company Limited, TelecomAsia. b. Network Equipment -- South Africa: The Group's operations in South Africa include the design, manufacture and supply of a range of terminal products including telephones, PABX key-systems and public payphones. On 23 December 2002, the Group disposed of its 51 per cent. interest in its optic fibre cable and copper cable business (ATC (Proprietary) Limited). NETWORK SERVICES The Group's Network Services activities comprise a broad range of support services to telecommunications operators and other providers of communication networks. The Group supports both its own products as well as those of other vendors of network equipment. Aggregate sales of all Network Services activities for the financial year ended 31 March 2002 were L969 million, (21.2 per cent. of total Group sales), compared to L1,016 million (14.6 per cent. of total Group sales) in the year ended 31 March 2001 and L543 million (9.5 per cent. of total Group sales) in the year ended 31 March 2000. Aggregate sales in the six months ended 30 September 2002 were L392 million (35.4 per cent. of total Group sales). Overview of the Network Services market The substantial reduction in sales of network equipment has led to corresponding reductions in the network planning, installation and commissioning services associated with the sales of new products. However, as network operators have sought to reduce expenditures to cope with excess capacity, the requirements for maintenance and support have continued and in some cases new opportunities have emerged as operators have sought to consolidate vendors and outsource additional services. Corp and plc believe this is a trend that is expected to continue and to mitigate, to some extent, the decline in sales of services related to new products sales. 47

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- The fragmented nature of the network support services market means there are no dominant competitors in the provision of services to the public network market. However, major telecommunications vendors, such as Alcatel, Cisco Systems, Ericsson and Lucent Technologies are extending their service capabilities to offer total solutions in direct competition to the Group. Major information technology and systems integrators, such as CSC, EDS and IBM, are now offering telecommunications solutions to their customers. Furthermore, independent service and support organisations such as Dimension Data and Telindus offer a broad portfolio of services. The principal method of competition in this market is through open bidding. Services may also be sold as a part of, or linked to, equipment sales. Service offerings The Group provides plan, build and operate support services to both fixed line and wireless network operators in many countries around the world. The Group targets customers in the service provider, large scale "carrier class" markets and in the government, transport and utilities sector. The services segment has two main sub-groupings: Installation, Commissioning and Maintenance comprises the following activities: a. Customer Fulfilment provides project management, installation and commissioning, field engineering support and customer training. The main markets are the UK, North America, Germany and Italy. The North American activities are associated with the OPP Business and will be included in the Ringfenced Entities post-Restructuring. b. Managed Services supports the installed base of the Group's equipment worldwide through technical support, on-site maintenance and spares & repairs management. Managed Services also remotely monitors, manages and supports customers' live networks. Services are provided from a global network of technical assistance centres ("TACs"), stock hubs and network operation centres ("NOCs"). The Group operates thirteen TACs (five in the US, two in the UK, two in the rest of Europe, two in Canada and one in each of Japan and Australia) offering around-the-clock telephone assistance to customers. It also has five NOCs (one in each of Australia, Germany, Italy, the UK and the US) for remote monitoring, fault diagnosis and network repair. The Group can support its own product range as well as products supplied by other communication equipment companies. c. Operational Support Systems provides the software systems and systems integration services that enable operators to maximise the efficiency of their networks and the quality of the services they provide to customers. The bulk of these services are related to the sale of the Group's products, although there is also considerable experience of working with equipment from other vendors. Value-Added Services comprise the following activities: a. Integrated Systems provides plan, build and operate services on major complex projects for non-telecommunications businesses in market sectors such as transportation and government. The projects involve planning, building, operating and supporting carrier class telecommunications infrastructure and are generally long-term. The principal geographical markets are the UK, Germany and the Middle East. b. Wireless Services provides radio frequency consulting services to both wireless and wireline network operators. These are primarily consulting and contractual services for site acquisition, mast design and construction, radio frequency cell site planning and network optimisation. The Group's radio planning and installation services enhance the Group's ability to offer customised, cost- effective solutions for network operators and service providers. In North America the primary focus is on radio cell site planning and network optimisation. In Europe, the Middle East and Africa (EMEA), the principal geographical markets are the UK, Saudi Arabia, the Netherlands and Germany. 48

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- c. Managed Services provides customer support services associated with the Group's BBRS equipment. These will be included in the Ringfenced Entities post-Restructuring. The services businesses have developed within the Group over a number of years. In EMEA, installation and commissioning services were necessary to support equipment sales to service providers. In North America, the business developed through supporting the data networking and power markets. The Integrated Systems activities have developed organically to support complex mission critical network projects for large enterprises. Wireless Services evolved from the acquisition of APT in the UK, TI Projekts in Germany and MSI. The Group intends to continue to drive process and efficiency improvements throughout Network Services' operations to reduce costs, improve customer satisfaction and increase both revenues and margins. In addition, the Group intends to increase the proportion of equipment sales that include support contracts and more cross-selling of existing services across markets and customers. Within Integrated Systems, the key initiative is to expand out of the strong UK base into carefully selected overseas markets (primarily Germany and Austria) through a combination of skills transfers and working with selected partners. The Group intends to grow the Wireless Services business by targeting mobile network operators operating 2G networks and planning 3G networks and equipment vendors providing turnkey projects to the mobile network operators who require service partners. CAPITAL BUSINESSES The Group's Capital Businesses comprise certain non-core businesses that the Group manages to create value and ultimately for disposal. Activities in Capital include the Group's holdings in: a. Easynet Group Plc: On 26 July 2001, the Group merged its 92 per cent. interest in ipsaris Limited into Easynet Group Plc ("Easynet"), a UK registered company listed on the London Stock Exchange, acquiring 71.9 per cent. of the issued share capital of Easynet and control of 49.9 per cent. of Easynet's issued voting capital. Easynet's share capital comprises voting ordinary shares and non-voting convertible shares. The closing of the Ultramast Limited capital reduction on 24 February 2003 and the settlement of the litigation associated with Ultramast Limited provided for the Group to acquire approximately a further 1.3 million ordinary shares in Easynet; certain of these shares will convert into convertible ordinary shares so that the Group will not own more than 49.9 per cent. of the voting ordinary shares. Easynet operates an internet network and data centre infrastructures. In the UK, Easynet has a national broadband network. Easynet is accounted for as an associate in the Group's consolidated accounts. b. Bookham Technology plc: On 17 December 2001, the Group sold its optical components business to Bookham Technology plc ("Bookham") in exchange for 9 per cent. of the issued ordinary shares of Bookham. Bookham is a provider of optical components to the Group and other network equipment vendors. Pursuant to a subsequent agreement between Bookham and Nortel Networks Corporation, Corp now owns approximately 6 per cent. of Bookham. c. Capital also includes the Group's Italian-based Public Mobile Radio Networks business, which develops base stations and controllers for 3G networks. Other activities in Capital include a number of minor activities, investments and assets. RESEARCH AND DEVELOPMENT The Group expended approximately L486 million, or 17.7 per cent. of total Core sales, on research and development ("R&D") in its Core businesses in the financial year ended 31 March 2002 (year ended 31 March 2001: L469 million). All of this amount was funded by the Group. During the six months ended 30 September 2002, the Group expended approximately L163 million, or 16.4 per cent. of total Core sales on R&D in its Core businesses. 49

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- The Group intends to continue to provide a competitive product portfolio building on existing market leading characteristics across its core product areas despite this reduction in expenditure. As revenues stabilise, the Group intends that R&D expenditure will amount to approximately 10 per cent. of expected Core sales. Optical Networks accounts for the Group's largest product portfolio and generates the largest revenue base. Optical Networks R&D expenditure reflects this representation and accounted for almost 40 per cent. of the total R&D expenditure in the Group's Core businesses during the six months ended 30 September 2002 (six months ended 30 September 2001: 30 per cent.). The current R&D projects have been selected on the basis that they are expected to yield a higher overall return for the Group. The Group is maintaining continued investment in next generation SDH products, in particular its recently launched Series 4 product range which has been designed to be more cost effective and offer service providers greater functionality than previous generations of the product. It is also focusing on the development of its next generation optical cross connect, the MSH range, its Metro product range, which is designed for metropolitan applications, as well as its long-haul DWDM products and further upgrades to the Group's network management software with the creation of elements to allow new product network integration and the development of a network control layer. Investment in network management should ensure that the Group's customers will retain a full optical network solution, which evolves along with individual product developments. The BBRS Business accounted for 23 per cent. of R&D expenditure in the Group's Core businesses in the six months ended 30 September 2002 (six months ended 30 September 2001: 21 per cent.). Over half of this expenditure was focused on the development of the Group's new multi-service core switch, the BXR-48000. In November 2002, the Group demonstrated its ability to support the transport of encrypted high speed data and high definition videos streams over the BXR-48000 using its newly developed 10 Gbps OC-192c ATM interface card. Ongoing initiatives on the BXR-48000 are focused on enhancing the product's IP functionality. Other ongoing programmes include the further development of the ASX-4000 switch to incorporate applications which will allow customers to transport voice traffic over ATM and IP infrastructures. R&D expenditure across the Group's European Access and North America Access Businesses combined, accounted for 25 per cent. of total R&D in the Group's Core businesses in the six months ended 30 September 2002 (six months ended 30 September 2001: 35 per cent.). During the first calendar quarter of 2002, the Group carried out an in-depth review of its complete portfolio of access solutions. This review was based on an evaluation of the forecast levels and timing of returns on investment and the cash generation potential of each product line. Following the review, the Group streamlined its portfolio of access technologies and refocused its R&D expenditure. In Europe, investment now only occurs in products that meet European Technology Standard Institute (ETSI) requirements and that will build on current market and customer positions. Consequently, R&D is being targeted on three key product ranges: the Access Hub platform, the Skyband fixed wireless access products and the Softswitch. Planned future developments of these products include the ability to aggregate traffic from 3G mobile base stations into the Access Hub, the addition of further frequency bands and voice and video functionality in the design of the fixed wireless products and the addition of further features and functionality to the Softswitch. R&D investment in North American access products has been significantly reduced and the Group has announced that while continuing to pursue sales opportunities and offer full support, care and maintenance for its existing copper and first generation fibre access products, it will not undertake further investment to develop next generation upgrades. In particular, the Group has discontinued investment in its next generation Fiber-to-the-Home solutions. Ongoing R&D efforts are focused on reducing the costs of existing products. The remaining R&D investment in the six months ended 30 September 2002 related mainly to outside plant and power products and wireless software. The Group is currently focusing its R&D efforts in the OPP Business towards the completion of its next generation power platform and web-based monitoring system. Smaller projects are also under way to develop customer specific products as well as redesigning the current product portfolio to reduce costs. The Group's wireless R&D efforts are focused on two product streams, OSS solutions and Wireless Network Planning solutions. A discussion of certain risks associated with the Group's R&D is set out in Part F of this section. 50

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- A.5 INTELLECTUAL PROPERTY BACKGROUND The Group owns a number of Intellectual Property rights including Patents, trade marks and registered designs throughout the world. The Group has a number of patent and know-how (and other) licences from third parties relating to products and methods of manufacturing products. The Group has also granted Patent, software, know-how and other licences to third parties. Because the Group has previously developed some of its technologies through customer-funded research, it may not always retain proprietary rights to the products it develops. The Group relies on Patents, trade marks, trade secrets, design rights, copyrights, confidentiality provisions and licensing agreements to establish and protect its proprietary technology and to protect against claims from others. Infringement claims have been and may continue to be asserted against the Group or against its customers in connection with their use of the Group's systems and products. The Group cannot ensure the outcome of any such claims and, should litigation arise, such litigation could be costly and time-consuming to resolve and could result in the suspension of the manufacture of the products utilising the relevant Intellectual Property. In each case, the Group's operating results and financial condition could be materially affected. See Appendix 20 for a discussion of significant legal proceedings. The "Marconi" trade mark used by many of the Group's businesses is identified with and important to the sale of the Group's products and services. It is either registered or the subject of an application for registration in approximately 120 territories, including all of those territories which the Group currently views as being its major trading territories. A discussion of certain risks associated with Intellectual Property rights is set out in Part F of this Section. PATENTS OWNED BY UK IP OPCOS AND US IP OPCOS As part of the security arrangements in relation to the New Notes to be implemented as part of the Restructuring all legal and beneficial title to Patents owned by the UK IP Opcos and US IP Opcos will be assigned to three SPVs, UK IPR Co, Ringfenced IPR Co and US IPR Co, which have been formed for the purpose of owning, maintaining and licensing the Patents assigned to them and all future Patent rights of Corp Group companies in the UK and US. UK IPR Co will be incorporated in England and Wales and Ringfenced IPR Co and US IPR Co will be incorporated in the State of Delaware, USA. US IP Opcos will grant security over all Intellectual Property prior to executing the assignments referred to in this paragraph. Further details are set out in Appendix 10. Ringfenced IPR Co will be a wholly-owned subsidiary of Marconi Communications, Inc. US IPR Co will be a wholly-owned subsidiary of Marconi Inc. UK IPR Co will be a wholly-owned subsidiary of Marconi Communications Limited. Ringfenced IPR Co will have assigned to it the Patents relating to the North American Access, BBRS and OPP Businesses operated by US IP Opcos. US IPR Co will have assigned to it the Patents owned by US IP Opcos that do not relate to North American Access, BBRS and OPP Businesses. UK IPR Co will have assigned to it the Patents owned by UK IP Opcos. Assignment to each SPV will be effected under an umbrella assignment. Each UK IP Opco and US IP Opco will be a party to the relevant assignment. The SPVs will not transfer, dispose of or grant any exclusive licence under any Patent, whether to another Corp Group company or a third party, other than: a. to another Corp Group company in the context of infringement proceedings against a third party where, absent such assignment, substantial damages would be irrecoverable (and in which case the Patent or Patents shall be reassigned to the relevant SPV as soon as such condition no longer prevails); 51

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- b. to a third party or a subsidiary of Corp, in each case in connection with any disposal (which is otherwise permitted by the applicable indenture pursuant to which the New Notes will be issued) of a Corp Group company or of all or substantially all of its assets, property or rights; or c. to a customer of Corp or any of its subsidiaries where the technology has been commissioned by that customer and developed by a Corp Group company (whether alone or jointly with the customer) for such customer's exclusive use pursuant to a development agreement. UK IPR Co will grant a non-exclusive licence to Marconi Communications Limited of all Patents assigned to it by UK IP Opcos. Ringfenced IPR Co will grant a non-exclusive licence to Marconi Communications, Inc. of all Patents assigned to it by US IP Opcos. US IPR Co will grant a non-exclusive licence to Marconi Inc. of all Patents assigned to it by US IP Opcos. All the licences will permit sub-licences to be granted subject to the provisions on Important Transactions described below. The management and maintenance of the UK and US owned Patents respectively will remain primarily with Marconi Communications Limited, Marconi Inc. and Marconi Communications, Inc. However, Important Transactions will require SPV approval. There will be three special categories of Important Transactions: a. granting sub-licences to third parties; b. pursuing/abandoning patent applications; and c. pursuing infringers. All Important Transactions will require the approval of the SPV but the SPV shall delegate that consent authority to Corp (which will act through Marconi Intellectual Property (divisional group)). This will ensure that the decisions regarding any Important Transaction are made with the interests of the entire Corp Group in mind (or at a minimum for any Patent, the interests of every other licensee within the Corp Group). At the same time, the decision could be taken expeditiously because it would be exercised by Corp and not a non-operating SPV. The approval requirements may not be waived or amended. New applications for Patents will be filed in the name of Marconi Communications, Inc., Marconi Inc. or Marconi Communications Limited (as appropriate) and assigned to the respective SPV. This will be achieved via a covenant in the indentures governing the New Notes on Corp to procure the assignment by Corp or a subsidiary of Corp organised in the UK or under US law of the Patent application from Marconi Communications, Inc., Marconi Inc. or Marconi Communications Limited to the relevant SPV. In the UK the application may be filed in the name of UK IPR Co at the outset. Each of the SPVs will grant security over its assets in favour of the Security Trustee, and the shares in the SPVs will be charged or pledged, as applicable, in favour of the Security Trustee on behalf of the holders of the New Notes and the banks providing the Performance Bonding Facility. Further details are set out in Appendix 10. In those cases (as set out in Appendix 10) where Guarantors grant floating charges (or equivalent security over all their assets) this will include such Intellectual Property as those Guarantors own. In some cases the Guarantors are required to grant a fixed charge or equivalent security over specified Intellectual Property in the future so far as such Intellectual Property is material and the security is legally permissible. OTHER INTELLECTUAL PROPERTY OF THE GUARANTORS As part of the security arrangements in relation to the New Notes, Intellectual Property owned by or registered in the name of Marconi Communications GmbH will be assigned to a Bank Trustee Company in Germany by way of security. The Bank Trustee Company will grant a licence to Marconi Communications GmbH. OTHER INTRA-GROUP LICENCES In consideration of the Parties sharing the costs incurred for research and development under the existing Research and Development Cost Sharing Agreement (RDCSA), each Party grants to the other Parties a royalty-free licence of Patents and technology developed by a Party under the RDCSA. Subject to the following 52

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- amendments listed below (and any further consequent changes that may be required as a result of the arrangements set out herein), the existing RDCSA will remain in force: a. the RDCSA will be varied/amended to allow Parties to sub-license Patents, subject to the procedure concerning Important Transactions described above; b. Marconi Communications, Inc. will withdraw from the RDCSA. This is because Marconi Communications, Inc. remains potentially liable for cost sharing under the RDCSA but accrues no commercial benefit through use of other Parties' Intellectual Property; c. the RDCSA will also be amended to confirm that the Parties to the RDCSA contract on behalf of themselves and their subsidiaries and related companies within their territory. Such subsidiaries and related companies will be entitled to claim the benefit of the provisions of the amended RDCSA; and d. the termination provisions of the RDCSA will be amended to state that the insolvency of any Party or its related companies and subsidiaries will not affect the rights enjoyed by those entities benefiting under a licence granted pursuant to the RDCSA. The SPVs will not be parties to the RDCSA. All Corp Group companies will enter into a Group Licence Agreement which will provide that each company grants a non-exclusive licence to the operating companies in the Corp Group of any Intellectual Property (other than trade marks and service marks) used in such other company's business to the extent that such use is not already authorised by the RDCSA or otherwise formally authorised in a written licence agreement. This Group Licence Agreement will only govern actual use by one Corp Group company of another Corp Group company's Intellectual Property. Each licensee Corp Group company shall pay a royalty (determined on an arm's length basis) to the licensor Corp Group company. The payment of that royalty shall become effective on a declaration of use by either the licensee or licensor and all royalties due from the date of the Group Licence Agreement shall immediately be payable by the licensee on the declaration of use being given or received, as the case may be. The Group Licence Agreement will have full effect to the extent that any operating company in the Corp Group lacks sufficient authorisation under the RDCSA. To the extent required, a licensee under the Group Licence Agreement will be permitted to grant sub-licences (subject, insofar as is necessary, to the provisions on Important Transactions described above). The Group Licence Agreement may not be varied or terminated so as to deprive a Corp Group company of the benefit enjoyed under such licence so long as it remains a part of the Corp Group. All future intra-Corp Group use of Intellectual Property (other than trade marks or service marks) which is not otherwise governed by the RDCSA or the Group Licence Agreement will be recorded in a written licence agreement. This will be achieved via a covenant in the indentures governing the New Notes on Corp to procure the execution of such agreements between the relevant operating companies in the Corp Group. A.6 DIVIDEND POLICY Under English law a company may only pay dividends out of profits available for distribution. Corp intends to apply to court to cancel its Non-Voting Deferred Shares and its share premium account (including the share premium account arising on the issue of the New Shares to be allotted pursuant to the Corp Scheme) to create a reserve which will be applied in writing off accumulated losses on its profit and loss reserve. It is anticipated that this Capital Reduction will become effective shortly after the Effective Date of the Corp Scheme, although no assurance can be given that the application will be successful. Further information concerning the Capital Reduction is set out in Part D.9 of this Section. Although the future ability of Corp to pay a dividend will be facilitated if the Capital Reduction is effected, Corp will be restricted from paying dividends under the terms of the indentures governing the New Notes (see Part C.3 of this Section and Appendix 8). Accordingly, Corp does not expect to pay a dividend in the foreseeable future. A discussion of certain risks associated with the dividend policy is set out in Part F: Risk Factors. A.7 FINANCIAL OBJECTIVES Upon completion of the Restructuring, the Group expects to be better positioned to compete effectively in the areas of the telecommunications market on which it has chosen to focus. Although the Group's principal markets 53

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- remain difficult, they are expected, at some stage, to recover as customers continue to evolve existing narrowband networks to broadband data and next generation mobile networks. In due course, this should allow the Group once again to grow profitably, assuming the telecommunications market improves. In the near-term the Group's financial strategy is to continue to reduce its total costs base to levels at which it can generate operating profit (before goodwill, amortisation and exceptional items) and to manage its capital expenditure and working capital in order to convert operating profit to positive operating cash inflows (before exceptional cash costs). The Group does not expect to rely on market recovery in order to achieve its target gross margin during the financial year ending 31 March 2004. The achievement of the Group's longer-term objectives is, however, dependent on an increase in sales following the expected improvement in the market for the Group's products and services. Further information in relation to the Group's financial objectives is contained in Appendix 5. A discussion of certain risk factors that could affect the Group's expectations with respect to the Group's return to operating profitability and ability to generate positive operating cash flow is set out in Part F of this Section. GROSS MARGIN IMPROVEMENT The Group expects to achieve a gross margin run-rate in the range of 24 to 27 per cent. of sales in the Core businesses during the financial year ending 31 March 2004. Of this, the Group expects that the Group's US businesses would contribute a gross margin run-rate in the range of 33 to 35 per cent. of sales while its businesses in Europe and the rest of the world would contribute a gross margin run-rate in the range of 23 to 26 per cent. of sales. The run-rate for the US Businesses has not been adjusted to take into account the disposal of any of the US Businesses. The Group aims to drive future gross margin improvement through focusing on sales of higher margin products and services, further supply chain rationalisation and additional planned product cost reductions (being materials and engineering cost reductions). In the longer-term, assuming the market recovers, a gross margin run-rate in excess of 30 per cent. is expected to be achievable. The Group will need to benefit from increased sales volumes over time in order to achieve this level of gross margin. When setting this longer-term target, the Group has assumed it will continue to be able to achieve annual product cost savings at least equal to the level of expected annual price reductions. OPERATING COST REDUCTION The Group's aim is to reduce operating overheads, comprising research and development, sales, marketing, general and administrative costs but excluding goodwill amortisation and exceptional items for the Core businesses, including OPP and North American Access to a run-rate of below L450 million during the financial year ending 31 March 2004. The Group aims to achieve an operating expenditure run-rate for the Core businesses in the range of 21 to 24 per cent. of sales during the financial year ending 31 March 2004. Of this, the Group expects that its US businesses would contribute an operating expenditure run-rate in the range of 29 to 33 per cent. of sales, while its businesses in Europe and the rest of the world would contribute an operating expenditure run-rate in the range of 20 to 23 per cent. of sales. The run-rate for the US Businesses has not been adjusted to take into account the disposal of any of the US Businesses. Once the Core businesses' operating expenditure target is achieved, the level of the Core businesses' sales at which the Group expects to be able to break even at an operating profit/(loss) level will be reduced to below L1.7 billion per annum. The Group expects the main driver of these targeted operating cost savings to be further planned reductions in its workforce resulting from further rationalisation of its activities, as well as natural attrition. Reduced spending on marketing initiatives and professional fees are also expected to contribute to operating cost savings. 54

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- Headcount in the Core businesses has been reduced by approximately 3,000 since the end of September 2002 and at the end of December 2002, was approximately 16,000. At that time, a further 1,400 leavers had been identified and announcements made in this respect, giving an identified headcount target for the Core businesses of around 14,600. Once the L450 million operating cost target has been achieved and the Group's headcount reduction plans have been completed, the Group expects to employ approximately 14,000 employees in its Core businesses. CASH Cash generation will continue to be one of the Group's key business priorities post-Restructuring. In particular, the Group is targeting (i) to reach operating cash breakeven before exceptional cash costs during the financial year ending 31 March 2004, and (ii) to generate sufficient total cash in order to pay down 30 per cent. of the New Junior Notes within 12 to 24 months following implementation of the Restructuring, to pay down 50 per cent. of the New Junior Notes within 15 to 27 months following implementation of the Restructuring and to pay down 100 per cent. of the New Junior Notes within 18 to 30 months following implementation of the Restructuring. The Group expects to retain a total cash balance of approximately L602 million upon completion of the Restructuring. Of this amount, approximately L96 million will represent net cash outflows to break even, approximately L112 million will be trapped cash, approximately L197 million is expected to be available to the Group to fund its normal working capital needs, approximately L30 million will represent cash in transit and approximately L167 million is expected to be retained for the cash collateralisation of performance bonds. See Part D.4 of this Section for more details on post-Restructuring retained cash. Cash to Breakeven and Operating Cash Flow The funds expected to be available to the Group include an amount derived from the approximately L96 million projected net cash outflow to allow the Group to fund the business to the point at which it reaches operating cash breakeven before exceptional cash costs. This net outflow includes approximately L27 million of cash which the Group expects to generate from disposals of certain non-core assets. Approximately L55 million has already been received by the Group (including proceeds from Ultramast Limited (L41 million), the sale of the Group's Italian-based private mobile network business, OTE SpA, also known as TETRA (L2 million) and other disposals totalling L12 million) which, under the terms of the Corp Scheme and the New Notes, will be available to fund its working capital requirements. The Group also intends to continue to improve management of the working capital cycle. Specific programmes are already in place to minimise the time during which cash is tied up in work in progress, to improve utilisation of inventory by better aligning the purchase of new inventory with forecast sales demand and to focus on debtor collection and overdue debts. Once the Group completes its on-going operational restructuring initiatives, including its headcount reduction plans, the Group expects the level of exceptional restructuring cash costs to reduce significantly. Paydown of New Junior Notes The Group expects to generate cash to pay down the New Junior Notes primarily from the proceeds of the disposal of OPP and North American Access, and other asset disposals not allocated to working capital requirements, as described above, as well as from the release of restricted cash balances relating to performance bonding. The North American Access Business may be sold prior to 1 May 2003, in which event, the net proceeds of the disposal will be applied to increase the cash element of the Corp Scheme Consideration (and the aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of that amount). SITE RATIONALISATION AND CLOSURES Since March 2002, the Group has further rationalised its remaining supply chain facilities in the UK, US, Germany and Italy. 55

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- It has also closed its outsourced printed circuit board (PCB) assembly and manufacturing facility in Liverpool and merged these activities with the facility managed by Jabil Circuit, Inc. (Jabil) in Coventry, and closed its facility in Ireland and transferred these manufacturing operations to Pittsburgh (US). In addition, Marconi has closed its SONET manufacturing facility in Montreal (Canada) as a result of the Group's decision to cease further development of this technology, and has reduced the number of production facilities for its outside plant and power equipment from nine to seven with the closure of two plants in Wisconsin and Illinois (US). In total, these site rationalisations and closures have resulted in a total reduction of 6,305 employees from the Core businesses between April and November 2002 as the businesses have been reduced/adjusted to align cost with the current and expected business volumes. Today, the Group's principal operating sites are Coventry, Beeston, Chorley, Camberley, Liverpool, London, Stafford and Wellingborough (UK); Florida, Pennsylvania, Ontario, Georgia, Mississippi, North Carolina, Illinois, Texas and Montreal (US & Canada); Genoa, Marcianise and Pisa (Italy); Backnang, Offenburg, Frankfurt and Radeberg (Germany); Madrid (Spain); Melbourne and Sydney (Australia); Beijing, Guilin and Hong Kong (China); Darulam and Kuala Lumpur (Malaysia); Auckland (New Zealand); New Delhi (India); Riyadh (Saudi Arabia); Dubai (United Arab Emirates); Springs (South Africa); Sao Paulo and Votorantim (Brazil); and Naucalpan de Juarez and Huixquilucan Edo de Mexico (Mexico). OUTSOURCING Marconi Communications and Jabil Circuit, Inc. (Jabil) entered into an agreement on 11 January 2001 to transfer certain manufacturing operations to Jabil. The transfer was completed in the UK, Italy and the US during 2001. The planned transfer of the Group's facility in Offenburg (Germany) did not proceed. Under the terms of the agreement, approximately 1,800 Group employees in Bedford, Texas (US), Liverpool and Coventry (UK) and Marcianise (Italy) transferred to Jabil. Following the business transfers, Jabil and its subsidiaries entered into agreements with Marconi Communications and other members of the Group to provide electronics manufacturing and repairs services until June 2005 on an exclusive basis. The operations outsourced under this agreement comprise the assembly and manufacture of PCBs used in the production of the Group's optical networking and broadband access equipment. The Group continues to perform the final assembly stages where the optical layer and power supply are applied to the PCBs. It also configures and tests the products according to the customers' specification and then packages and delivers the products to customers. The majority of the Group's PCB assembly and manufacture for its broadband switching and routing equipment is already outsourced to Jabil (Florida) and Solectron (Texas). The Group has retained control of the manufacture of its fixed wireless access equipment in Germany. Since the outsourcing to Jabil was implemented, Marconi Communications and Jabil have regularly reviewed their arrangements with a view to improving the efficiency of their respective operations. For example, the transferred plant at Bedford, Texas (US) was closed during 2002. On 22 January 2003, Marconi Communications and Jabil agreed to a further rationalisation of Jabil's UK operations which is intended to deliver improved pricing for the Group. The Group will contribute towards the costs of securing these improvements. As part of these arrangements, Marconi Communications and Jabil have entered into new agreements governing the provision of electronics manufacturing and repair services by Jabil, which will provide for more flexible and competitive pricing and are currently expected to take effect from June 2003. Under these new agreements, Jabil will continue to provide services to the Group until at least June 2005 (the expiry date of the original service agreements), and to June 2007 for certain repair services. Jabil will continue, subject to meeting certain performance and capacity requirements, as the exclusive supplier for products and services covered by the agreements. Marconi Communications and Jabil will continue to review their arrangements from time to time and, where further improvement plans are agreed, Marconi Communications may contribute to the costs of securing those improvements. 56

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- In addition to the arrangements with Jabil, Marconi Communications has established strategic relationships with a number of contract electronic manufacturers (CEMs), OEMs and component commodity suppliers. Examples of CEMs with whom Marconi Communications has established strategic relationships include Solectron Corporation, Sanmina/SCI and Teradyne. Examples of the OEMs include Hewlett-Packard, Siemens, Paradyne Corporation and Avaya. Finally, examples of component commodity suppliers include Bookham Technology, Corning Incorporated, Highwave, Intel Corporation, Molex, Motorola, NEC Electronics and Toshiba. As part of the Group's overall manufacturing strategy, the Group is currently considering further potential outsourcing opportunities in its supply chain, logistics organisations and in the field of information technology. The Group intends to retain control of functions only where it possesses key competencies. Other functions, such as the manufacturing of non-complex products, will continue to be outsourced where suitable partners can be identified. A discussion of certain risks associated with outsourcing is set out in Part F of this document. A.8 CURRENT APPLICATION OF CRITICAL ACCOUNTING POLICIES Corp and plc prepare their financial statements and accompanying notes in accordance with UK GAAP. One of the notes to the financial statements included in this document describes the significant accounting policies used in their preparation. The preparation of such financial statements requires Corp and plc to make estimates, judgements, and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Corp and plc base their estimates on historical experience and various other assumptions that they believe are reasonable under the circumstances, the results of which form the basis for making judgements about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Corp and plc believe that the following are some of the more critical judgement areas in the application of their accounting policies that currently affect their financial position and results of operations. The development and selection of these critical accounting estimates has been discussed with Corp's and plc's audit committees. REVENUE RECOGNITION Revenue is recognised when all of the following conditions are satisfied: (i) there is persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) it is probable that the debtor will be converted into cash. It is common for the Group's sales agreements to cover the delivery of several products and/or services. These range from arrangements where a contract covers the delivery and installation of equipment to more complex arrangements, which also include training of customer personnel, sale of software and other support services. Revenue from contracts with multiple element arrangements, such as those including installation and commissioning services, is recognised as each element is earned based on objective evidence of the relative fair values of each element and when there are no undelivered elements that are essential to the functionality of the delivered elements. Revenues and estimated profits on long-term contracts are recognised under the percentage-of-completion method of accounting using a cost-to-cost methodology. Significant judgement is required in determining progress toward completion and in estimating revenues and costs. Profit estimates are revised periodically based on changes in facts in the underlying contract. When estimates of total contract revenues and costs indicate a loss, a provision for the entire amount of the contract loss is recognised in the period in which the loss becomes foreseeable. Advance payments received from contracts are recorded as a liability unless there is a right of set-off against the value of work undertaken. 57

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- IMPAIRMENT OF LONG-LIVED ASSETS The Group reviews the carrying value of other fixed assets and assets to be disposed of, including other intangible assets, whenever indicators of impairment exist. Indicators of impairment include (but are not limited to): a. a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; b. a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; and c. a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. These tests for impairment require significant judgements in determining estimates of future cash flows and the resulting value in use of the relevant fixed asset. Estimations of the present value of future cash flows contain inherent uncertainty and include estimates of market size and market share information, growth rates, product demand and technological development, costs of labour and supplier purchases, working capital requirements, and discount rates to be applied to future cash flows. If the carrying value of a fixed asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the fixed asset exceeds the higher of its net realisable value or its value-in-use. Changes in estimates of future cash flows can affect the determination of the net realisable value or its value-in-use of the relevant fixed asset. CONTINGENT LIABILITIES Corp and plc are subject to legal proceedings and other claims arising in the ordinary course of business. Various claims and proceedings have been or may be instituted or asserted against Corp and plc relating to class shareholder actions and the conduct of their businesses, including those pertaining to patents, environmental, safety and health, employment and contract matters. Corp and plc are required to assess the likelihood of any adverse judgements or outcomes to these matters, as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is based on a careful analysis of each individual issue with, where appropriate, the assistance of outside legal counsel to formulate best estimates of the expected outcome and settlement. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavourably compared to the amounts estimated. PENSION AND OTHER POST-RETIREMENT BENEFITS Pension and other post-retirement benefits' costs and obligations are dependent on actuarial assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on plan assets, mortality rates, and other factors. While Corp and plc believe that the assumptions used are appropriate, the assumptions used may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants. These differences may result in a significant impact on the amount of future pension or post retirement benefits expense and the resulting liability. PRODUCT WARRANTIES Provisions for estimated expenses related to product warranties are made at the time products are sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims. The Group actively studies trends of warranty claims and takes action to improve equipment quality and minimise warranty claims. Actual claims incurred could differ from the original estimates, requiring adjustments to the reserve. If Corp and plc were to experience an increase in warranty claims compared with their historical experience, or if costs of servicing warranty claims were greater than the expectations on which the accrual had been based, the Groups' gross margins could be adversely affected. 58

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- A.9 CURRENT TRADING AND PROSPECTS CURRENT TRADING Overall conditions in the telecommunications market remained tough during the third quarter of the financial year ending 31 March 2003. Trading levels in EMEA in the third quarter remained stable despite the continuing difficult market environment. The Group is now beginning to observe some slowing of business in the Middle East as a result of the current political environment. The North American market continues to be characterised by further tightening of capital expenditure by a number of large telecommunications operators, particularly towards the end of their financial years in December 2002. In Central and Latin America (CALA), the market was relatively stable during the quarter although capital expenditure amongst major operators in the region remained at a low level. In Asia-Pacific (APAC), while the market remains buoyant in Australia, conditions in the Chinese market are more difficult as a result of delays in capital expenditure due to the reorganisation of key customers, delay to the roll-out of certain network build projects and increased pricing pressure on new business. Despite the difficult market environment, the Group continued to make significant progress during the third quarter of the financial year ending 31 March 2003 towards its targets to improve operating performance in the Core business. In particular compared to the previous quarter, further cost savings achieved during the period led to an approximate 0.5 percentage point increase in Core gross margin (before exceptional items) to 22.1 per cent. and an approximate L85 million deduction in Core operating cost run-rate (before goodwill amortisation and exceptional items) to around L550 million at 31 December 2002. Headcount reductions are a major driver of the Group's cost reduction initiatives. At 31 December 2002, the Group had just over 16,000 employees in its Core business, down from just over 19,000 at 30 September 2002. The Group's improved operating performance combined with further progress in all areas of working capital management, led to a significant improvement in adjusted operating cash flow, with the Group recording an operating cash inflow (before exceptional items) of L72 million during the quarter. Non-operating and exceptional cash outflows (excluding tax) of L88 million relating mainly to the Group's ongoing operational and financial restructuring processes and interest paid were partially offset by a net L45 million tax repayment received during the period. In total during the third quarter, the Group generated cash of L29 million before use of liquid resources and financing. The Group was awarded a number of important business wins during the period. These included the first European sale of the Group's BXR-48000 multi-service switch-router to a large financial institution and the first sale of the Group's recently launched Softswitch to Jersey Telecom. In addition, since the beginning of the new calendar year 2003, the Group has announced two major new business wins from Telecom Italia: a euro 80 million (approximately L50 million) frame contract for the supply of the Access Hub and a new 2-year frame contract estimated at approximately euro 15 million (approximately L10 million) to build an optical backbone network architecture based on the Group's next generation digital cross-connect, the MSH2K. PROSPECTS Upon completion of the Restructuring, Corp and plc expect the Group to be better-positioned to compete effectively in the areas of the broader telecommunications equipment market on which it has chosen to focus. The market for telecommunications equipment and services remains difficult. During the first three quarters of the financial year ending 31 March 2003 the annualised rate of Core sales has declined by around 10 per cent. from approximately L2 billion in the first quarter to approximately L1.8 billion in the third quarter. Corp and plc do not expect that the Group will benefit from a seasonal uplift in Core sales during the fourth quarter of the financial year compared to the level recorded in the third quarter (L456 million), contrary to the seasonal pattern of customer demand in previous years. Despite this difficult business environment Corp and plc believe that the previously announced cost reduction initiatives currently being implemented will enable the Group to make further progress during the final quarter of the financial year ending 31 March 2003 towards its near term financial objectives to reduce costs and to achieve operating cash breakeven before exceptional cash costs. Furthermore, Corp and plc believe that market volumes are likely to contract further during the financial year ending 31 March 2004 and do not expect to benefit from significant market share gains. As a result, the Group 59

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- believes that Core sales could decline by up to a further 5 per cent. during the financial year ending 31 March 2004 compared to the annualised third quarter trading levels (L1.8 billion). In December 2002, the Group outlined its Core operating model and confirmed its targets to achieve a gross margin run-rate in the range of at least 24 to 27 per cent. of Core sales and an operating expenditure run-rate in the range of 21 to 24 per cent. of Core sales during the financial year ending 31 March 2004. The Group now believes that it will be able to reduce the Core operating cost base to an annual run rate below L450 million during the next financial year ending 31 March 2004 and thereby reduce its breakeven level of sales to below L1.7 billion per annum. An illustration of the effect of the Corp Scheme and the Capital Reduction on the 30 September 2002 consolidated balance sheet of Corp is contained in Appendix 2. Although the Group's principal markets remain difficult, Corp and plc expect them to recover, at some stage, as end customer demand for fixed or mobile broadband services increases. While Corp and plc cannot predict with any level of certainty the occurrence, timing or extent of any recovery, they believe that the favourable longer-term dynamics of the telecommunications market should enable the Group to improve margin and grow profitably.

EMPLOYEES The table below sets out the average number of people (full time equivalents) employed by the Group in the previous three financial years and the six months ended 30 September 2002: <Table> <Caption> 30 September 2000 2001 2002 2002 ---- ---- ---- ------------ (in thousands) <S> <C> <C> <C> <C> Average number of employees Employees by business Network Equipment 20 24 19 13 Network Services 5 9 8 6 Other 1 1 -- -- ---- ---- ---- ------------ 26 34 27 19 Capital 11 3 3 3 ---- ---- ---- ------------ Continuing operations 37 37 30 22 Discontinued operations 12 15 15 3 ---- ---- ---- ------------ Group employees 49 52 45 25 Share of joint venture employees 4 4 3 -- ---- ---- ---- ------------ Group and share of joint ventures 53 56 48 25 ---- ---- ---- ------------ Employees by location United Kingdom 20 22 17 8 The Americas 16 17 12 6 Rest of Europe 11 13 15 9 Africa, Asia and Australasia 6 4 4 2 ---- ---- ---- ------------ 53 56 48 25 ==== ==== ==== ============ </Table> During the year and six months ended 30 September 2002, the Group took a number of steps to reduce its workforce as the Group restructured its cost base in response to the deterioration in trading conditions it experienced. At the end of December 2002, the Group employed approximately 16,000 employees in its Core business. SHARE INCENTIVE PLANS The Group currently operates various share incentive plans, providing participants with the right to acquire shares in plc at specified prices or, where certain objectives are achieved, at no cost (the latter are known as nil-cost options). Certain options, including some of the nil-cost options are already exercisable. The holders of such options can acquire plc Shares prior to the plc Shareholders Record Time. As a result of the Restructuring, more of the options will become exercisable. However, this will be after the plc Shareholders Record Time, when plc Shares will have no value. Due to plc's current share price the majority of options granted to participants under the Plans are now underwater (that is, shares in plc are worth less than participants would have to pay to acquire them under the Plans). It is therefore assumed that holders of those options, which are currently exercisable, will not exercise them. Of those options where the plc Shares subject to them are worth more than the price that participants must pay for them, it is only those optionholders who can and do exercise their options prior to the plc Shareholders 63

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- Record Time who will receive New Shares and Warrants. After the Restructuring, all remaining options over plc Shares will be valueless. Details of the Group's existing share incentive plans are contained in Part D.10 of this Section. Conditionally on the later of the First Initial Distribution under the Corp Scheme being initiated, and the Effective Date of the Corp Scheme, Corp has adopted two employee share option plans, the Corp Senior Management Share Option Plan and the Corp Employee Share Option Plan. Summaries of the plans are contained in Part D.10 of this Section. CORP CORPORATE GOVERNANCE Corp supports high standards of corporate governance. Corp intends to comply with the requirements of the Combined Code following the Restructuring. Following Listing of the New Shares, the New Notes and the Warrants, Corp's Board will comprise the Chairman, three Executive Directors (including the Chief Executive Officer) and four Non-Executive Directors. Corp regards all Non-Executive Directors as independent and free from any business or other relationship which could materially interfere with the exercise of their independent judgement. The Board has established audit, remuneration, nomination and executive committees. The audit committee will comprise a chairman and will have at least two other members each of whom will be appointed by the Board and who will be Non-Executive Directors of Corp. The audit committee will be chaired by Kent Atkinson; its other members will be Ian Clubb and Werner Koepf. It will meet formally at least twice a year. Its duties will include reviewing the scope, plan and results of any audit. It will meet regularly with management, as well as with internal and external auditors to review the effectiveness of internal controls, as well as matters raised in regular reports to the committee. It will review financial announcements and annual reports prior to their submission to the Board. Corp's auditors will be able to attend meetings and have the opportunity to raise matters or concerns in the absence of Executive Directors and management. The remuneration committee will comprise at least three Non-Executive Directors. The remuneration committee will be chaired by Ian Clubb; its other members will be Kent Atkinson, Kathleen Flaherty and Werner Koepf. The committee will meet formally at least twice a year. The committee will make recommendations to the Board on the broad policy to be adopted for executive remuneration, including the remuneration of Executive Directors and the Chairman. It will determine the total individual remuneration package for individual Executive Directors and certain other senior executives including, where appropriate, bonuses, pensions and incentive scheme entitlements and the terms of individual Executive Directors' service agreements. The nomination committee will comprise the Chairman and each of the Non-Executive Directors. The nomination committee will be chaired by John Devaney and its other members will be Kent Atkinson, Ian Clubb, Kathleen Flaherty and Werner Koepf. The committee will meet to review Board structure, size, composition and balance, to make recommendations to the Board on any adjustments that are deemed necessary and to nominate candidates to fill board vacancies. Following the recent publication of the Higgs "Review of the Role and Effectiveness of Non-Executive Directors" and the Smith Report "Audit Committees -- Combined Code Guidance", Corp intends to review those areas of its corporate governance which are impacted by the Review and the Report. This will include the structures and terms of reference of its committees, in order to ensure the Corp's continued future compliance with the requirements of the Combined Code. In particular, Corp believes that it should move to a position where the majority of its Board are independent Non-Executive Directors. Although Corp does not envisage that any further non-executives will be appointed to the Board before the Listing of the New Shares, the New Notes and the Warrants, Corp will continue to look for suitable candidates to join the Board as independent Non-Executive Directors, where they can bring appropriate experience or industry knowledge. A process is already in place to identify further suitable candidates. Following a further appointment which it expects will be made within three months of the Effective Date, Corp will at all times strive to ensure that it maintains a majority of independent Non-Executive Directors on its Board by within 64

EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART A -------------------------------------------------------------------------------- three months of ceasing to have such a majority, appointing additional independent Non-Executive Directors or reducing the size of the Board. Corp's executive committee comprises such Executive Directors and senior executives of the Corp Group as the Chief Executive Officer recommends and the Board approves. The committee normally meets monthly and is chaired by Michael Parton. Its other members are Michael Donovan, Christopher Holden, David Beck, Geoffrey Doy, Mary Skelly, Damian Reid, Neil Sutcliffe, Michael Surrey and Patricia Dooley. The committee approves the Corp Group's business plan, budget and strategies in areas including technology, people, information technology and corporate communications prior to submission to the Board for approval. It also approves day-to-day matters of a routine nature. The business risk sub-committee of the executive committee comprises the members of the executive committee and meets at least four times a year. It establishes and monitors risk management goals and objectives, embeds a risk monitoring and assessment process throughout the Corp Group and regularly reports on the same to the Board. The sub-committee also liaises with the audit committee to ensure a sound system of internal control and reports to the audit committee, at least annually, with an update on the Corp Group's risk management system. Corp will also be subject to applicable corporate governance requirements under US law (including the Sarbanes-Oxley Act of 2002 and regulations adopted by the SEC thereunder) and, after the listing of its ADRs becomes effective, NASDAQ rules.

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART B -------------------------------------------------------------------------------- B. BACKGROUND TO AND REASONS FOR THE RESTRUCTURING The trading statement made by plc on 17 May 2001 in relation to the Group's results for the year ended 31 March 2001 highlighted the fact that conditions in the telecommunications equipment sector had experienced a downturn since the end of 2000. On 4 July 2001, plc issued a profits warning noting that market conditions during the three months to June 2001 had been much tougher than expected, and that there had been a marked deterioration in the short-term outlook for the Group (in particular, that sales were expected to be down by 15 per cent. and operating profit before exceptional items by 50 per cent. compared with the previous financial year). Immediately prior to the announcement, plc suspended trading in its shares for a day. On 6 July 2001, plc announced the resignation of John Mayo as Deputy Chief Executive of plc. An operational review of the Group was commenced shortly thereafter, the outcome of which included sharper focus on the Core carrier-class network communications business and a disposal programme in relation to certain non-Core businesses and assets. plc issued a second profits warning on 4 September 2001. The 4 September 2001 trading statement, which indicated that a first half operating loss of L227 million was expected, also announced a change in senior management (namely the resignations of Sir Roger Hurn and Lord Simpson as Chairman and Chief Executive respectively of plc, and the appointment of Derek Bonham as interim Chairman and Michael Parton as Chief Executive), a decision to halt dividend payments for the financial year ending 31 March 2002 and the implementation of further cost reduction measures. In October 2001, in view of the deterioration in the Group's financial condition and the need to procure medium term financing for the Group, Corp and plc entered into negotiations with the Syndicate Banks for the refinancing of Corp's then existing E4.5 billion and (undrawn) E3 billion revolving credit facilities (due to mature in March 2003 and May 2002 respectively) (referred to in this Part B as the "EXISTING SYNDICATED FACILITIES"). By mid-March 2002, Corp and plc had largely agreed the terms of a L1.95 billion facility agreement with the then Syndicate Banks in order to refinance the existing syndicated facilities. However, market conditions had continued to deteriorate and, following further reviews of the Group's then business plan in the second half of March 2002, the boards of Corp and plc reached the view that the refinancing proposal would no longer provide the Group with an appropriate capital structure and, accordingly, that they were unable to enter into the proposed new L1.95 billion facility. On 22 March 2002, plc made an announcement to this effect and announced also that Corp and plc had agreed to cancel the undrawn commitments under the existing syndicated facilities (as the E3 billion facility was undrawn, this resulted in the complete cancellation of this facility) and to place on demand the drawn portion of the E4.5 billion facility (approximately L2.2 billion). Over subsequent weeks, the Group developed a revised Business Plan, which was then presented to representatives of the Syndicate Banks and to the Informal Committee of Bondholders. In parallel, Corp and plc commenced tripartite discussions with those representatives with a view to Corp and plc formulating a Restructuring proposal. As part of that negotiation process, in April/May 2002 Corp and plc agreed to certain restrictions on financial and corporate activities during the Restructuring process, in the form of undertakings given by Corp and plc (in relation to each member of the Group) in favour of the Syndicate Banks and members of the Informal Committee of Bondholders respectively. These undertakings, which were modified and renewed on 28 March 2003, are aimed at preservation of the "status quo" over the period of the Restructuring negotiations and while the Schemes are pending. The undertakings contain a number of carve outs designed to preserve operational (but not strategic) flexibility and to facilitate the implementation of the Restructuring. The undertakings will terminate automatically on the Effective Date of the Corp Scheme. With effect from 1 April 2002, and also as part of the undertakings, Corp agreed to increase the margin above LIBOR on Corp's drawings under the Bank Facility to 2.25 per cent. per annum. As part of the undertakings, Corp agreed to deposit L850 million of the Group's cash balance into certain accounts held with banks independent of the Syndicate Banks, and agreed to restrictions on withdrawals of cash from those accounts. The Lockbox Accounts, into which the L850 million was deposited on 3 May 2002, are held in the name of Highrose Limited, a special purpose subsidiary of Corp. 66

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART B -------------------------------------------------------------------------------- On 29 August 2002, the Group announced that following good faith negotiations with the Co-ordination Committee and the Informal Committee of Bondholders, it had concluded non-binding indicative Heads of Terms setting out principles for the Restructuring of Corp and plc. On 13 September 2002, as detailed further in Part D.1 of this Section, the Group announced the grant of interim security over the Lockbox Accounts, in favour of the Group's Bank Creditors and Secured Bondholders and Barclays Bank PLC, as the only ESOP Derivative Bank which committed to support the Restructuring prior to 15 October 2002. Although withdrawals from the Lockbox Accounts to fund the Group's working capital requirements since May 2002 have reduced the balance of the Lockbox Accounts, significant disposal proceeds have been paid into the Lockbox Accounts, as required under the undertakings. At the date of the granting of the interim security, the balance held in the Lockbox Accounts was approximately L866 million. As at 27 March 2003, the balance held in the Lockbox Accounts was approximately L770.7 million. On 16 December 2002, plc announced modifications to the non-binding indicative Heads of Terms and amendments to the interim security over the Lockbox Accounts. The interim security was further amended on 28 March 2003 (see Part D.1 of this Section). Provision has been made for the interim security to be released prior to the Corp Scheme Meeting (in circumstances tied to the prospects of the Corp Scheme being successfully implemented (as described more fully in Part D.1 of this Section)). If the interim security has not been released prior to the Corp Scheme Meeting, neither Corp nor plc will proceed with their respective Schemes and the interim security will remain in place in any subsequent insolvency proceedings, meaning that the Bank Creditors, Secured Bondholders and Barclays Bank PLC (as the only ESOP Derivative Bank that committed to support the Restructuring prior to 15 October 2002) would rank ahead of all unsecured creditors of Corp with respect to the cash held in the Lockbox Accounts. If the interim security is released and the Corp Scheme Meeting proceeds, the choice facing all Corp Scheme Creditors will be the same: either the Corp Scheme will be approved and implemented, or the Corp Scheme will be rejected and in the inevitable insolvency proceeding which would follow such rejection the interim security would no longer be in place. The Syndicate Banks and the Informal Committee of Bondholders have indicated that they will not be prepared to release the interim security prior to the Corp Scheme Meeting unless, immediately before such release, Corp has confirmed to the Prospective Supervisors that Corp remains satisfied that the reserves built into the Corp Scheme are sufficient to meet distributions to all Corp Scheme Creditors and that Corp remains of the opinion that its statement as to the Corp Group's working capital contained in Part D.21 of this Section remains valid, and the Prospective Supervisors have confirmed to Corp that they have no reason to disagree with Corp's view that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors. On 18 March 2003, plc announced that documentation in relation to the proposed Restructuring had been filed with the Court and provided an update on certain aspects of the Restructuring. On 26 March 2003 and 24 March 2003 respectively the required consents were received to certain pre-completion steps for the Restructuring from the requisite majorities of the Syndicate Banks and the members of the Informal Committee of Bondholders. On 26 March 2003, Corp and plc entered into a definitive agreement with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group. Under the terms of the settlement, which is conditional upon the Corp Scheme becoming effective, Corp will pay a total of L35 million to the ESOP Derivative Banks in full and final settlement of their ESOP related claims against the Group. On 28 March 2003, the undertakings agreed by Corp and plc in April and May 2002 were renewed and modified. As a result of that modification, on the release of the interim security the "Lockbox" provisions of the undertakings will govern withdrawals of cash from the Lockbox Accounts (see Part D.1 of this Section). 67

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART B -------------------------------------------------------------------------------- Since August 2001, in view of the deterioration in the Group's financial condition, there have been the following credit rating downgrades in respect of the Group: Standard & Poor's 6 August 2001, BBB+ to BBB- 5 September 2001, BBB- to BB 21 Jan 2002, BB to B+ 22 March 2002, B+ to B- 4 April 2002, B- to CC Moody's 10 August 2001, A3 to Baa2 7 September 2001, Baa2 to Ba1 15 October 2001, Ba1 to Ba3 15 January 2002, Ba3 to B1 26 March 2002, B1 to Caa3 Corp and plc believe that there are only two possible outcomes of the Group's current financial difficulties, which are the reorganisation of their liabilities through the proposed Schemes or the placing of the companies into administration or liquidation. As discussed in Part C.10 of this Section, Appendix 6 contains an insolvency analysis providing a detailed analysis of the position of Corp and plc should they be subject to insolvency proceedings (and the assumptions, caveats, limitations and uncertainties on which such analysis is based). 68

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- C. PROPOSED RESTRUCTURING C.1 OVERVIEW The Restructuring will be effected through two schemes of arrangement under the Act. A scheme of arrangement is a court-supervised procedure under English law through which a company may enter into a compromise or arrangement with its creditors to effect a restructuring of its financial obligations. The Corp scheme of arrangement will involve all creditors of Corp at the Record Date, excluding certain categories of creditors, but including the Syndicate Banks and Bondholders to whom the Group's primary financial indebtedness is owed. The plc scheme of arrangement will involve all creditors of plc at the Record Date, excluding certain categories of creditors, the liabilities to some of which are to be novated to Corp (with effect from the Effective Date of the Corp Scheme), but including the Syndicate Banks and Bondholders. Creditors whose claims are to be compromised through the Schemes are referred to as "SCHEME CREDITORS" (but see "Definitions and Interpretation" on page 12 for a further explanation of this term) and the claims of these creditors are referred to as "SCHEME CLAIMS". Assuming the English Court makes an order sanctioning the Schemes, Corp and plc will apply, before the Schemes become effective, for permanent injunction orders under Section 304 of the US Bankruptcy Code (the "BANKRUPTCY CODE") to give effect to their respective Schemes. Through the Restructuring, Corp will become the new parent holding company of the Group. All of plc's assets (net of a reserve to meet plc's Ongoing Costs) will be distributed to its creditors over time in accordance with the plc Scheme, following which it is intended that plc will be liquidated or dissolved. C.2 TERMS OF THE RESTRUCTURING CORP SCHEME The Corp Scheme will compromise approximately L4.0 billion of externally held financial indebtedness, comprising principally the Bank Facility and the Bonds. In addition, the Corp Scheme will compromise certain other claims and contingent claims, including those discussed under "Summary of key actual and contingent claims" below. In exchange for the compromise of their Scheme Claims, Corp's Scheme Creditors will receive a distribution, pro rata in proportion to their Admitted Scheme Claims, of a package of cash and new equity and debt securities issued by Corp. This package of cash and securities is referred to as the "SCHEME CONSIDERATION". The Corp Scheme Consideration is to comprise the following: a. CASH: L340 million cash; b. NEW SENIOR NOTES: the euro equivalent (calculated at the Currency Rate) of L450 million in aggregate principal amount of new guaranteed senior secured notes due April 2008 to be issued by Corp denominated in euro and/or US dollars, subject to elections made in Claim Forms and Account Holder Letters, with interest payable quarterly in cash at a rate of 8 per cent. per annum; c. NEW JUNIOR NOTES: the sum of US$300 million plus the US dollar equivalent (calculated at the Currency Rate) of L117.27 million in aggregate principal amount of new guaranteed junior secured notes due October 2008 to be issued by Corp denominated in US dollars, with interest payable quarterly in cash at a rate of 10 per cent. per annum or, at Corp's option, in kind (by issuing additional New Junior Notes) at a rate of 12 per cent. per annum; and d. NEW SHARES: 995,000,000 ordinary shares, representing 99.5 per cent. of Corp's issued ordinary share capital immediately following implementation of the Restructuring. Elections may be made in Claim Forms and Account Holder Letters to have all or any portion of the New Shares deliverable pursuant to the Schemes delivered in the form of ADRs. The cash element of the distribution to Corp's Scheme Creditors will be increased by the net proceeds of any asset disposals, other than L82 million of excluded asset disposal proceeds, received on or after 1 December 2002 and before 1 May 2003, and the aggregate principal amount of the New Junior Notes will be decreased by 69

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- 10/11ths of the sterling amount by which the cash element is increased (such calculation to reduce the L117.27 figure referred to in c. above). PLC SCHEME The plc Scheme will compromise approximately L3.9 billion of externally held liabilities of plc as guarantor in respect of financial indebtedness, comprising principally the Bank Facility and the Bonds. In addition, the plc Scheme will compromise other claims and contingent claims, including those discussed under "Summary of key actual and contingent claims" below. In exchange for the compromise of their Scheme Claims, plc's Scheme Creditors will receive a distribution, pro rata to their Admitted Scheme Claims, of all plc's assets (net of a reserve for plc's Ongoing Costs). These assets will principally comprise a portion of the Scheme Consideration to be distributed by Corp pursuant to the Corp Scheme, which plc will receive as a result of a repayment of capital in specie by plc's wholly-owned subsidiary Ancrane, one of the Scheme Creditors of Corp. ELECTION TO RECEIVE AMERICAN DEPOSITARY RECEIPTS Elections may be made in Claim Forms and Account Holder Letters to have all or any portion of the New Shares deliverable pursuant to the Schemes delivered in the form of ADRs. Any person who elects to receive New Shares in the form of ADRs will receive all future distributions of New Shares to which such person may be entitled pursuant to the Schemes in the form of ADRs. As described below, no depositary fees will be payable at any time in connection with the initial issuance of ADRs pursuant to the Schemes and any UK stamp duty or SDRT payable in this respect will be met by Corp. ADRs will be issued pursuant to the Schemes in reliance on the exemption from Securities Act registration provided by Section 3(a)(10) thereof (or, in the case of plc Shareholders, in transactions not subject to such registration). Following their initial issuance, such ADRs may be sold in ordinary secondary market transactions without restriction under the Securities Act (subject to the restrictions applicable to "affiliates" described in Part D.16 of this Section). In addition, a registration statement on Form F-6 will be filed with the SEC in relation to the ADRs. It is currently expected that this registration statement will be effective prior to the Effective Date of the Corp Scheme. Once this registration statement is effective, outstanding Corp Shares may be deposited into the ADR programme in exchange for ADRs. Such ADRs may then be sold in ordinary secondary market transactions without restriction under the Securities Act. Corp will apply to list the ADRs on NASDAQ and will use its reasonable endeavours to effect this NASDAQ listing as soon as practicable following the Effective Date of the Corp Scheme. It is currently expected that the NASDAQ listing will become effective during the third calendar quarter of 2003. Persons who are considering making an election to receive New Shares in the form of ADRs should note that, unless and until the NASDAQ listing becomes effective, although ADRs will be free to trade over-the-counter, development of a liquid trading market for the ADRs will be inhibited, which is likely to have a material adverse effect on the value of the ADRs. A summary of the material terms of the ADRs is set out in Appendix 16. Information as to responsibility for fees and taxes in connection with ADRs is contained in Part D.15 of this Section. NEW SHARES AND WARRANTS TO BE ISSUED TO PLC SHAREHOLDERS As part of the Restructuring, plc Shareholders on the register as at the plc Shareholders Record Time will receive 5 million New Shares, representing 0.5 per cent. of Corp's issued ordinary share capital immediately following implementation of the Restructuring, along with up to 50 million Warrants to subscribe for additional shares equal to an aggregate of up to 5 per cent. of Corp's issued ordinary share capital at that date. Each existing plc Shareholder will receive at least one New Share. Warrant entitlements will be rounded down to the nearest whole Warrant and each Warrant will entitle its holder to subscribe one Corp Share (subject to adjustment in the event of certain corporate actions). The exercise price of the Warrants will be 150p per share (again subject to adjustment in the event of certain corporate actions). An ordinary share price of 150p implies a post Restructuring market capitalisation of Corp of approximately L1.5 billion. The Warrants will expire four years 70

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- after the Restructuring becomes effective if not exercised. The conditions of the Warrants are set out in Appendix 12. New Shares and Warrants will be given to plc Shareholders under the Corp Scheme. The New Shares are to be issued in return for the compromise and release of Scheme Claims against Corp by the Corp Scheme Creditors. The New Shares and Warrants to be given to plc Shareholders who hold their plc Shares in CREST will be credited to the same CREST accounts. plc Shareholders who hold a plc share certificate, are aged under 18 or have a registered address outside the UK, Channel Islands, Isle of Man or Ireland will receive a certificate in respect of their New Shares and, if applicable, Warrants. The New Shares and, if applicable, Warrants to be given to plc Shareholders who hold a plc share certificate, are aged under 18 or have a registered address outside the UK, Channel Islands, Isle of Man or Ireland will be held in a nominee account on their behalf operated by Corp's registrars. Pursuant to the Corp Scheme, New Shares will be issued to The Bank of New York, as depositary (the "PLC ADR DEPOSITARY") in respect of the existing American depositary receipt programme relating to the plc Shares (the "PLC ADR PROGRAMME"), in common with other plc Shareholders. In accordance with the deposit agreement for the plc ADR programme, plc and the plc ADR Depositary have consulted with respect to these New Shares, and have agreed that the plc ADR Depositary will arrange for persons who hold plc Shares in the form of American depositary receipts ("PLC ADRS") to receive their interest in respect of this distribution in the form of ADRs representing Corp Shares. No depositary fees will be payable in connection with the initial issuance of these ADRs. SDRT, however, will be payable in this connection at a rate of 1.5 per cent. of the market value of the New Shares deposited into the Corp ADR programme. The plc ADR Depositary will, on behalf of the holders of plc ADRs, sell any New Shares relating to their fractional ADR entitlements together with such number of additional New Shares to which they would be entitled as may be necessary to cover the amount of SDRT that is due. A summary of the material terms of the ADRs is set out in Appendix 16. Also pursuant to the Corp Scheme, Warrants will be issued to the plc ADR Depositary in common with other plc Shareholders. In accordance with the deposit agreement for the plc ADR programme, plc and the plc ADR Depositary have consulted with respect to these Warrants, and have determined that it is unlikely that a liquid market for Warrants will develop in the United States, and that it would be unreasonably costly to seek to distribute Warrants directly to holders of plc ADRs. Accordingly, at an appropriate time, the plc ADR Depositary will sell any such Warrants it has received and will distribute the net proceeds of such sale to holders of plc ADRs, all in accordance with the deposit agreement for the plc ADR programme. C.3 TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES Set out below is a summary of the principal terms of the New Notes comprising part of the Scheme Consideration. See Appendix 8 for the detailed terms of the New Notes and for definitions of terms used in this Part C.3 that are not otherwise defined in part V. Principal Amount and Currency The New Senior Notes will have an aggregate principal amount of the equivalent (calculated at the Currency Rate) of L450 million. Elections may be made in Claim Forms delivered under each Scheme and in Account Holder Letters to elect for all, but not part of, the New Senior Notes to be received by Scheme Creditors and Designated Recipients to be denominated in euros or US dollars. No New Senior Notes denominated in US dollars will be issued unless, based on all Claim Forms received before 5:00 p.m. (London time) on 17 April 2003 and all Account Holder Letters delivered before 5:00 p.m. (New York City time) on 17 April 2003, elections have been made which would, if both Schemes become effective, result in an aggregate of at least the US dollar equivalent (calculated at the Currency Rate) of euro 250 million (less the Relevant Deduction) of New Senior Notes denominated in US dollars being required to be issued in the First Initial Distribution under both Schemes. No New Senior Notes denominated in euro will be issued unless, based on all Claim Forms received before 5:00 p.m. (London time) on 17 April 2003 and all Account 71

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Holder Letters delivered before 5:00 p.m. (New York City time) on 17 April 2003, elections have been made which would, if both Schemes become effective, result in an aggregate of at least euro 250 million (less the Relevant Deduction) of New Senior Notes denominated in euro being required to be issued in the First Initial Distribution under both Schemes. The New Junior Notes will have an initial aggregate principal amount equal to the sum of US$300 million plus the US dollar equivalent (calculated at the Currency Rate) of L117.27 million, unless the cash element of the distribution to Corp Scheme Creditors is increased by the net proceeds of any asset disposals (in which event, the initial aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of the sterling amount by which the cash element is increased (such calculation to reduce the L117.27 million figure referred to above)). The New Junior Notes will be denominated in US dollars. Interest The New Senior Notes will bear interest from their issue date at a per annum rate of 8 per cent. payable quarterly in cash on each 15 January, 15 April, 15 July and 15 October, commencing 15 July 2003. On the first interest payment date for the New Senior Notes, Corp will pay, in addition to accrued interest on the outstanding principal amount of the New Senior Notes, an amount per New Senior Note equal to the amount of interest that would have accrued on such New Senior Note if such New Senior Note had been outstanding for the period from 1 May 2003 to the issue date of the New Notes. The New Junior Notes will bear interest from their issue date at a per annum rate of 10 per cent. payable quarterly in cash or, at Corp's option, at a per annum rate of 12 per cent. payable quarterly in kind (by issuing additional New Junior Notes to the holders of New Junior Notes) on each 31 January, 30 April, 31 July and 31 October, commencing 31 July 2003. On the first interest payment date for the New Junior Notes, Corp will pay, in addition to accrued interest on the outstanding principal amount of the New Junior Notes, an amount per New Junior Note equal to the amount of interest that would have accrued on such New Junior Note if such New Junior Note had been outstanding for the period from 1 May 2003 to the issue date of the New Notes. Maturity The New Senior Notes will mature on 30 April 2008. The New Junior Notes will mature on 31 October 2008. Optional Redemption All of the outstanding New Notes may be redeemed at Corp's option in whole, but not in part, at any time at a redemption price in cash equal to the greater of (i) 110 per cent. of their principal amount, and (ii) a make-whole amount equal to the sum of the present values of remaining scheduled payments of principal and interest, using a discount rate that is 50 basis points above the yield on US treasuries of similar maturity to the New Senior Notes and New Junior Notes, as applicable, plus, in each case, accrued and unpaid interest. Mandatory Redemption The New Notes are subject to mandatory early redemption in certain circumstances. The New Notes must be redeemed prior to their stated maturity in whole or in part using the proceeds from the Mandatory Redemption Escrow Account, which is an escrow account to be established for redemption of the New Notes into which Corp will be required to deposit, from time to time: 72

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- - releases to, or upon the order or instructions of, Corp or its subsidiaries of certain cash collateral security for performance bonding (as described in more detail in Part D.4 of this Section); and - all net proceeds of asset sales received on or after 1 May 2003, other than up to L82 million of net proceeds from disposals of certain exempt specified assets and, if there are no New Junior Notes outstanding, proceeds reinvested in the non-US core business within specified time periods. Corp will apply amounts in the Mandatory Redemption Escrow Account to redeem first the New Junior Notes and then, under certain circumstances, the New Senior Notes, in each case at a redemption price in cash of 110 per cent. of their principal amount plus accrued and unpaid interest. In addition, in the event of either a Change of Control of Corp or the merger, consolidation or sale of all or substantially all the assets of Corp and its subsidiaries, taken as a whole, all of the New Notes must be redeemed in whole, but not in part, at a redemption price in cash equal to the greater of (i) 110 per cent. of their principal amount, and (ii) a make-whole amount equal to the sum of the present values of remaining scheduled payments of principal and interest, using a discount rate that is 50 basis points above the yield on US treasuries of similar maturity to the New Senior Notes and New Junior Notes, as applicable, plus, in each case, accrued and unpaid interest. Covenants The New Senior Notes and the New Junior Notes will be issued under indentures that will contain certain restrictive covenants. The restrictive covenants will include, among other things: - restrictions on indebtedness, guarantees, sale and leaseback transactions and the issuance of preferred stock; - restrictions on dividends, distributions, investments and other restricted payments; - restrictions on acquisitions; - restrictions on liens; - restrictions on derivative transactions; - restrictions on transactions with affiliates (including Ringfenced Entities); - restrictions on the issuance and sale of equity interests in Corp's subsidiaries; - restrictions on asset sales; and - restrictions on mergers, consolidations and sales of all or substantially all assets. Each of the covenants will be subject to exceptions and qualifications. In addition, under the indenture governing the New Senior Notes (but not the New Junior Notes), beginning as of 30 September 2005 the Group will be required to meet financial covenants with respect to a minimum ratio of consolidated EBITDA to consolidated finance charges and a maximum ratio of consolidated indebtedness to consolidated EBITDA, in each case 73

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- calculated with respect to the consolidated Group (but excluding the Ringfenced Entities if any New Junior Notes are outstanding). The indentures will provide for customary grace periods and remedies. When the New Senior Notes and the New Junior Notes are simultaneously outstanding, however, the indentures will provide for longer grace periods and require a larger percentage of the noteholders to take enforcement action in the case of certain non-payment covenant defaults. Purchase of New Notes The indentures governing the New Notes will provide that Corp and its subsidiaries may purchase outstanding New Notes only after the second scheduled Senior Note Interest Payment Date or Junior Note Interest Payment Date, as the case may be, and then only if (a) no Default or Event of Default under the New Senior Note indenture (in the case of the New Senior Notes) or the New Junior Note indenture (in the case of the New Junior Notes) has occurred and is continuing; (b) interest on the immediately two preceding Junior Note Interest Payment Dates was paid in cash (rather than in kind); and (c) Corp has not given notice of an intention to pay interest on the next Junior Note Interest Payment Date in kind. US Ringfencing The covenants in the indentures governing the New Notes will restrict the financial, operational and other dealings that the Non-Ringfenced Entities can have with the Ringfenced Entities. The covenants for the New Notes will also require Corp to separate the North American Access Business, BBRS Business and OPP Business into separate subsidiaries (or groups of subsidiaries) within the US Ringfencing no later than the second anniversary of the issue date of the New Notes. Moreover, the Non-Ringfenced Entities will generally be prohibited from providing funding for any of the Ringfenced Entities and, following the separation of the three principal businesses within the US Ringfence, the North American Access Business, BBRS Business and OPP Business will generally be prohibited from providing funding to each other. See Part A.2 of this Section for a description of the US Ringfencing. Guarantees and Security Corp's obligations under the New Notes will be guaranteed by, inter alios, Corp's principal operating subsidiaries. With limited exceptions, the Guarantor coverage must include on an ongoing basis (i) subsidiaries that together account for at least 80 per cent. and (ii) each subsidiary that individually accounts for more than 5 per cent., in each case, of the total assets, total external assets, total external sales and (commencing as of 31 March 2005) EBITDA of Corp and its subsidiaries. Corp and the Guarantors will, with limited exceptions, grant security over substantially all of their respective assets to secure their respective obligations under the New Notes and the guarantees thereof as well as the Performance Bonding Facility. Payment Priorities Corp, the Guarantors and the trustees for the New Notes, among others, will enter into a Security Trust and Intercreditor Deed that will establish the relative priorities among the New Senior Notes, New Junior Notes, the Performance Bonding Facility and certain intra-Group liabilities with respect to the obligations of Corp and the Guarantors. Following the occurrence of a payment Default and/or an acceleration of the maturity of the New Senior Notes, all proceeds from enforcement of the security granted by Corp and the Guarantors (where such Guarantors 74

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- are providers of security) to secure their respective obligations under the New Notes and the guarantees thereof and the Performance Bonding Facility will be applied as follows: - first, to the fees and expenses of the trustees and other agents; - second, to the lenders providing the Performance Bonding Facility; - third, to the repayment of the New Senior Notes; and - fourth, to the repayment of the New Junior Notes. Payment and Security Enforcement Blocks Under the terms of the Security Trust and Intercreditor Deed and the indentures for the New Notes, no payments may be made on the New Junior Notes (other than payments of interest in kind) and no redemptions of the New Junior Notes from amounts contained in the Mandatory Redemption Escrow Account may be made (subject to limited exceptions) (i) upon the occurrence of a Default under the New Senior Notes and the delivery of notice of such Default by the Senior Note Trustee to the Security Trustee for a period lasting until the earlier of (a) the expiration of 179 days after the date of such notice, (b) the date on which such Default is no longer continuing, (c) the date on which the holders of a majority of the principal amount of the New Senior Notes consent, or (d) the payment in full of all obligations under the New Senior Notes and the New Senior Note indenture, or (ii) upon the occurrence of a payment Default or acceleration of the New Senior Notes following an Event of Default under the New Senior Notes or the New Senior Note indenture until the earlier of (a) the date on which the payment Default has been remedied or waived and, if the New Senior Notes have been accelerated, the acceleration has been rescinded, (b) the date on which the holders of a majority of the principal amount of the New Senior Notes consent, or (c) the payment in full of all obligations under the New Senior Notes and the New Senior Note indenture. The Security Trust and Intercreditor Deed further provides that in the event of a default under the New Senior Notes, the holders of the New Junior Notes may not accelerate the New Junior Notes during the 179-day or shorter period referred to in clause (i) of the previous sentence. In addition, under the terms of the Security Trust and Intercreditor Deed, the holders of the New Junior Notes may not take enforcement action against any security securing the New Junior Notes without the consent of the holders of the New Senior Notes or unless all liabilities arising under the New Senior Notes have been discharged in full. The Security Trust and Intercreditor Deed further provides that if a payment default occurs under the Performance Bonding Facility, the lenders thereunder may require the obligors to provide full cash collateral to cover all outstanding liabilities but may not accelerate the liabilities under the Performance Bonding Facility or take the other enforcement action for 180 days unless the New Senior Notes have been accelerated. Security Numbers The CUSIP for the New Senior Notes denominated in euro (if any are issued) will be G58129AB6. The CUSIP for the New Senior Notes denominated in US dollars (if any are issued) will be G58129AA8. The CUSIP for the New Junior Notes will be G58129AD2. Further details of the security and intercreditor arrangements affecting the New Notes are set out in Appendix 10. 75

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- C.4 SUMMARY OF KEY ACTUAL AND CONTINGENT CLAIMS Schedule 3 to the Corp Scheme in part II contains a list of Scheme Creditors who may have a Scheme Claim. The aggregate amount (in sterling) of claims listed in Schedule 3 in part II is approximately L5.193 billion. The fact that a claim is listed in Schedule 3 at a certain amount does not mean that the particular claim will be Admitted at that, or any other, amount. There are three principal areas of actual and contingent claims listed in Schedule 3 to the Corp Scheme: a. BANK FACILITY AND BOND DEBT: Corp is indebted as at the Record Date to: (i) the Syndicate Banks pursuant to the terms of the Bank Facility in the principal sums of US$2,226,600,000 and L650,000,000, together with accrued but unpaid interest of US$40,271,358 and L18,199,947; (ii) the relevant Bondholders pursuant to the terms of the 2005 Eurobonds in the principal sum of E500,000,000 together with accrued but unpaid interest of E12,559,932; (iii) the relevant Bondholders pursuant to the terms of the 2010 Eurobonds in the principal sum of E1,000,000,000 together with accrued but unpaid interest of E28,469,178; (iv) the relevant Bondholders pursuant to the terms of the 2010 Yankee Bonds in the principal sum of US$900,000,000 together with accrued but unpaid interest of US$31,687,500; and (v) the relevant Bondholders pursuant to the terms of the 2030 Yankee Bonds in the principal sum of US$900,000,000 together with accrued but unpaid interest of US$34,218,750; b. INDIRECT CLAIMS BY PLC: these comprise claims under inter-company loan balances and through ownership (via Ancrane) of some of the indebtedness listed in (ii) to (v) above (E324,603,000 and US$261,101,000 of the principal sum is owed to Ancrane). Corp and plc currently anticipate that these claims (inclusive of accrued but unpaid interest) will amount to approximately L776 million in aggregate; and c. OTHER THIRD-PARTY AND ASSOCIATED COMPANY CLAIMS: these are expected to include claims under various loans, guarantees, and a US class action and other lawsuits, as well as other potential claims. In light of the detailed due diligence that has been undertaken in relation to its financial indebtedness, Corp acknowledges that the principal amount of the claims of the Syndicate Banks and the claims in respect of the Bonds set out in a. above are due and owing and anticipates that these claims, in each case together with interest accruing pursuant to the terms of the Bank Facility or the terms of the relevant Bonds, as appropriate, for the period up to, and including, the Record Date, will be Admitted in the amounts set out in Schedule 3 to the Corp Scheme in part II. Schedule 3 to the plc Scheme in part III contains a list of Scheme Creditors who may have a Scheme Claim. The aggregate amount (in sterling) of claims listed in Schedule 3 in part III is approximately L4.68 billion. The fact that a claim is listed in Schedule 3 at a certain amount does not mean that the particular claim will be Admitted at that, or any other, amount. There are two principal areas of actual and contingent claims listed in Schedule 3 to the plc Scheme: a. GUARANTEES OF CORP'S BANK FACILITY AND BOND DEBT: plc has guaranteed the indebtedness of Corp listed in paragraph a. above; and b. OTHER THIRD-PARTY CLAIMS: these are expected to include claims under various loans, guarantees, and a US class action and other lawsuits, as well as other potential claims. In light of the detailed due diligence that has been undertaken in relation to its financial indebtedness, plc acknowledges that the principal amount of the claims of the Syndicate Banks and the claims in respect of the Bonds under the guarantees referred to in a. above are due and owing and anticipates that these claims, in each case together with interest accruing pursuant to the terms of the Bank Facility or the terms of the relevant Bonds, 76

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- as appropriate, for the period up to, and including, the Record Date, will be Admitted in the amounts set out in Schedule 3 to the plc Scheme in part III. Claims that would be barred by statute or claims that are otherwise unenforceable in England and Wales or which arise under a contract which is void or, being voidable, has duly been avoided, are not liabilities for the purposes of the Schemes. C.5 COMPLETION OF THE RESTRUCTURING As discussed in more detail in Part B of this Section, if the interim security is not released prior to the Corp Scheme Meeting, neither Corp nor plc will proceed with its respective Scheme (see Part D.1 of this Section for further detail on the circumstances in which the interim security is expected to be released). Each of the Schemes becoming effective will be dependent on, among other things, securing the necessary support of the Scheme Creditors in the relevant Scheme Meeting to be held as part of the scheme of arrangement process, as well as the sanction of the English Court and the granting of a permanent injunction order by the US Bankruptcy Court. No assurance can be given that Corp and plc will be able to satisfy the conditions to completion of the Restructuring (described in more detail below), or that circumstances will not arise that otherwise make it impossible to proceed with the Restructuring. Certain risks related to a failure to implement or a delay in implementing the Restructuring, risks arising from implementation of the Restructuring, operating risks and risks related to ownership of the New Shares, the New Notes and the Warrants are set out in Part F of this Section, Risk Factors. While the Corp Scheme will not be conditional upon the plc Scheme becoming effective, the plc Scheme will be conditional on the Corp Scheme becoming effective. Any order approving the plc Scheme will not be delivered to the Registrar of Companies (which delivery would make the plc Scheme effective) until an order approving the Corp Scheme has been similarly delivered. The Schemes will not be conditional on the Listing of the New Shares, the New Notes and/or the Warrants. However, it is expected that the New Shares, New Notes and Warrants will be listed on the Effective Date of the Corp Scheme. Corp will use its reasonable endeavours to effect the Listing of the New Shares, the New Notes and the Warrants as soon as possible on or after the Effective Date of the Corp Scheme. (See details of risks arising from implementation of the Restructuring in Part F.2). The Schemes will not be conditional on the approval of plc Shareholders. The Co-ordination Committee and the Informal Committee of Bondholders with whom Corp and plc negotiated the Heads of Terms indicated that they would not be prepared to support a Restructuring that requires plc Shareholder approval on the grounds that, considering the financial condition of the Group and the economic interest of plc Shareholders, such a vote would be inappropriate. Corp and plc believe that if the Syndicate Banks and the Informal Committee of Bondholders withdraw their support for the Restructuring, Corp and plc will be forced to commence insolvency proceedings. On this basis, Corp and plc approached the UKLA for a waiver of the requirement to seek plc Shareholder approval in connection with the Restructuring. The UKLA has granted this waiver. The New Shares to be allotted pursuant to the Corp Scheme will be paid up by the release of, or agreement not to commence or continue prohibited proceedings in respect of, both liquidated and unliquidated Scheme Claims. The Act requires the consideration for an allotment of shares partly paid up by the release of liabilities for unliquidated sums to be independently valued prior to allotment, and accordingly Corp has engaged BDO Stoy Hayward to prepare and deliver a report complying with the provisions of the Act before the New Shares are allotted. CONDITIONS TO EFFECTIVENESS OF THE SCHEMES In order to ensure that certain conditions are satisfied before the Schemes can come into effect, Corp and plc will not deliver a copy of any Court order sanctioning the Schemes for registration to the Registrar of Companies in England and Wales until the relevant conditions are satisfied. Corp will not take the necessary steps to make the Corp Scheme effective unless and until: (a) Corp has, following the passing of a unanimous Board resolution to approve the same, provided confirmation in writing to 77

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- the Prospective Supervisors (for the sole benefit of the Prospective Supervisors) prior to each of (i) the release of the interim security granted by Corp through its special purpose subsidiary Highrose Limited, (ii) the Corp Scheme Meeting, (iii) the hearing to sanction the Corp Scheme and (iv) the Effective Date, to the effect that Corp remains satisfied that the reserves built into the Corp scheme are sufficient to ensure the same level of distribution will be made to all Corp Scheme Creditors and that Corp remains of the opinion that its statement as to the Corp Group's working capital contained in Part D.21 of this Section remains valid; (b) the Prospective Supervisors of the Corp Scheme have provided confirmation in writing to Corp (for Corp's sole benefit) on the day of, but prior to, each of events (i) to (iv) above to the effect that they have no reason to disagree with Corp's view that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors; (c) a permanent injunction order of the US Bankruptcy Court under Section 304 of the Bankruptcy Code has been granted in respect of the Corp Scheme; and (d) all conditions precedent (other than those relating to the Corp Scheme becoming effective) set out in the Working Capital Facility and the Performance Bonding Facility are satisfied or waived by the facility agents. Corp will undertake to the Court to file the Court order approving the Corp Scheme with the Registrar of Companies as soon as the conditions set out above are satisfied provided such conditions are satisfied on or before 19 June 2003. plc will not take the necessary steps to make the plc Scheme effective unless and until: (a) plc has, following the passing of a unanimous Board resolution to approve the same, provided confirmation in writing to the Prospective Supervisors (for the sole benefit of the Prospective Supervisors) prior to each of (i) the release of the interim security granted by Corp through its special purpose subsidiary Highrose Limited, (ii) the plc Scheme Meeting, (iii) the hearing to sanction the plc Scheme and (iv) the Effective Date, to the effect that plc remains satisfied that the reserves built into the plc Scheme are sufficient to ensure the same level of distribution will be made to all plc Scheme Creditors; (b) the Prospective Supervisors of the plc Scheme have provided confirmation in writing to plc (for plc's sole benefit) on the day of, but prior to, each of events (i) to (iv) above to the effect that they have no reason to disagree with plc's view that the reserves built into the plc Scheme are sufficient to meet distributions due to be made to all plc Scheme Creditors; (c) a permanent injunction order of the US Bankruptcy Court under Section 304 of the Bankruptcy Code is granted in respect of the plc Scheme; and (d) a copy of the Court's order sanctioning the Corp Scheme has been delivered for registration to the Registrar of Companies in England and Wales. plc will undertake to the Court to file the Court order approving the plc Scheme with the Registrar of Companies as soon as the conditions set out above are satisfied provided such conditions are satisfied on or before 19 June 2003. Corp will not pursue a permanent injunction order of the US Bankruptcy Court unless the English Court makes an order sanctioning the Corp Scheme. plc will not pursue a permanent injunction order of the US Bankruptcy Court unless the English Court makes orders sanctioning both the Corp Scheme and the plc Scheme. If a Scheme has not been made effective on or before 19 June 2003, the Scheme will be withdrawn and not made effective. WITHDRAWAL OF SCHEMES As a result of the extensive due diligence undertaken by Corp and plc and having taken account of the results of the advertising process, Corp and plc are satisfied that the Reserve Claims Segment in respect of each of the Corp and plc Schemes will be sufficient to ensure the same level of distribution will be made to all plc Scheme Creditors. In addition the Prospective Supervisors have confirmed that they have no reason to disagree with that view. In order for the Schemes to proceed the Scheme Companies must indicate that they remain satisfied that the Reserve Claim Segment under each Scheme will be sufficient to meet distributions due to be made in respect of Reserve Claims in accordance with the terms of the Schemes. If each Scheme Company remains so satisfied, each Scheme Company will give written confirmations on certain key dates set out below. 78

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Board meetings of each Scheme Company will be held at 5.00 pm on the calendar day before each of the following key dates: a. the Release Date; b. the date of the Scheme Meetings; c. the date of the commencement of the Court sanction hearing; and d. the Effective Date, (each of a. to d. above being a "CONFIRMATION DATE"). The Board meetings will consider whether the Board can pass the Confirmatory Resolution and whether the relevant Scheme Company is able to deliver the Scheme Company Confirmation to the Prospective Supervisors confirming that the relevant Scheme Company remains satisfied that the level of reserves built into each of the Schemes will be sufficient to ensure the same level of distribution will be made to all relevant Scheme Creditors and, in the case of Corp, that the statement as to the Corp Group's working capital contained in Part D.21 of this Section remains valid. On receipt of the Scheme Company Confirmation, the Prospective Supervisors will be required to consider whether, based on the information available to them at that time, they are able to confirm in writing that they have no reason to disagree with the relevant Scheme Company's view that the level of reserves built into each of the Schemes will be sufficient to ensure the same level of distribution will be made to all relevant Scheme Creditors by delivering the Supervisor's Confirmation to the relevant Scheme Company by 7.00 a.m. on each Confirmation Date. Unless the relevant Scheme Company receives the Prospective Supervisor's Confirmation by 7.00 a.m. on each Confirmation Date, the relevant Scheme Company will not proceed with the proposed Scheme and the relevant Scheme will be withdrawn. If the Corp Scheme is withdrawn then the plc Scheme will also be withdrawn, but the Corp Scheme will not be withdrawn only because the plc Scheme is withdrawn. C.6 MECHANICS OF THE RESTRUCTURING OVERVIEW OF THE SCHEMES As mentioned above, the Schemes are Court sanctioned compromises under section 425 of the Act between each of Corp and plc and their respective Scheme Creditors. These creditors comprise all of the creditors of Corp and plc with the exception of certain "Excluded Creditors" (the identity of the Excluded Creditors and the basis upon which their claims are to be excluded are set out in Appendix 9). No allotment and issue or transfer of securities (or the cash proceeds of sale thereof) or cash will be made to any person where prohibited by any applicable law or regulation. The Court gave directions on 24 March 2003 for Scheme Meetings of Scheme Creditors of Corp and plc to be convened respectively for 10.00 a.m. and 10.15 a.m. (or as soon as possible thereafter following the conclusion or adjournment of the first meeting) on 25 April 2003. Notices convening the Scheme Meetings for these times are set out in part VI, Sections A and B of this document. The Scheme Meetings will take place at the Institute of Civil Engineers, 1 Great George Street, London SW1. To become effective, the Schemes must be approved by Scheme Creditors at a Scheme Meeting. The Schemes each require the approval of a majority in number representing three-fourths in value of the Scheme Creditors present and voting (in person or by proxy) at each Scheme Meeting. The Schemes must then receive the sanction of the Court. It is currently anticipated that the Court hearing to sanction the Schemes will take place on 12 to 13 May 2003. The Schemes are set out in full in parts II and III of this document. VOTING ON THE SCHEMES Scheme Creditors are entitled to attend and vote at the Scheme Meetings either in person or by proxy. Although the Eurobond Trustee and The Bank of New York are both Corp Scheme Creditors and the Eurobond Trustee and 79

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- the Yankee Bond Trustee are both plc Scheme Creditors, none of them has any economic interest in the Bonds in respect of which they are the trustee or the depositary, as the case may be. Bondholders in respect of Eurobonds and Yankee Bonds represented by a global Eurobond or a global Yankee Bond, as the case may be, are not Scheme Creditors. Accordingly, certain creditors have requested Corp to exchange the global Yankee Bonds for definitive Yankee Bonds and the global Eurobonds for individual global Eurobonds, in each case with a view to ensuring that Definitive Holders in whose names Yankee Bonds are registered or who become the bearers by attornment of the Eurobonds after such exchange can attend and vote at the Corp Scheme Meeting, and have requested plc to extend the benefit of its guarantees of the Eurobonds and the Yankee Bonds to the Definitive Holders of such Bonds with a view to ensuring that the Definitive Holders can attend and vote at the plc Scheme Meeting in respect of such Bonds. Corp, plc and, in the case of the request to exchange Eurobonds, the Eurobond Trustee, have each agreed to these requests. Definitive Holders of Bonds who wish to attend and/or vote at the Scheme Meetings must ensure that this is specified in the Account Holder Letter delivered by their Account Holder. Further instructions are set out in Appendix 28. Only the votes of Scheme Creditors voting at the Scheme Meetings in person or by proxy can be taken into account for the purpose of establishing whether the requisite approval for the Schemes has been obtained. In order to attend and vote at the Scheme Meetings Scheme Creditors (other than Definitive Holders) must complete and lodge a Form of Proxy (as summarised below). Further instructions are set out in Appendix 27. Definitive Holders may arrange for forms of proxy to be completed on their behalf by Bondholder Communications by ensuring that their Account Holder gives appropriate instructions on their behalf in the Account Holder Letter. Further instructions are set out in Appendix 28. VOTING BY PROXY Scheme Creditors (other than Definitive Holders) Set out at Appendix 29 is a form of Form of Proxy for use by Scheme Creditors (other than Definitive Holders) in voting on the Schemes. The relevant Form of Proxy should be completed in accordance with the instructions set out on it, indicating the value of the Scheme Claim, including interest accruing on it, if any, for the period up to and including the Record Date. See below for an explanation of the value of a Scheme Creditors' Claim for voting purposes. Corp and plc may require details of any Scheme Creditors' entitlement to Scheme Claims in order to establish their entitlement to vote. Instructions to this effect are set out on the Forms of Proxy. Scheme Creditors (other than Definitive Holders) are requested to complete the relevant Form of Proxy in accordance with the instructions set out on it and return it to KPMG LLP, 8 Salisbury Square, London EC4Y 8BB, England, UK, for the attention of Philip Wallace, by 12 noon (London time) on 24 April 2003 (although it is recommended that they be received by 5.00 p.m. (London time) on 17 April 2003). If for any reason this cannot be done, Forms of Proxy may be handed in at the registration desk at the relevant Scheme Meeting and Scheme Creditors are urged to do so no later than one hour before the scheduled time of the relevant Scheme Meeting. Thereafter Scheme Creditors (other than Definitive Holders) may lodge completed Forms of Proxy with the chairman of the relevant Scheme Meeting at that Scheme Meeting. Forms of Proxy may be returned by fax (to fax number +44 (0)20 7694 3011 marked for the attention of Philip Wallace and Richard Heis). The lodging of a Form of Proxy in advance of the Scheme Meeting does not prevent a Scheme Creditor from revoking such proxy and delivering a new Form of Proxy on the date of the Scheme Meeting or revoking such proxy and attending in person. Please read the instructions on the Forms of Proxy carefully before completing it. Failure to complete the Form of Proxy in accordance with those instructions may result in your vote being disallowed. 80

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Definitive Holders Each Definitive Holder who wishes authority to be given to Bondholder Communications to appoint a proxy to attend a Scheme Meeting on his behalf will be required to ensure that his Account Holder gives the appropriate instructions in the Account Holder Letter on his behalf. Account Holder Letters should be returned to Bondholder Communications by 5:00 p.m. (New York City time) on 17 April 2003. Failure to deliver an Account Holder Letter to Bondholder Communications by the time and date specified above does not preclude the relevant Definitive Holder from voting at the Scheme Meetings provided that the Definitive Holder or his proxy can establish his entitlement by producing a copy of the Account Holder Letter or form of proxy (which should be obtained from Bondholder Communications), as the case may be, to the registration desk or the chairman of the relevant Scheme Meeting. Detailed instructions explaining the action to be taken by persons with interests in Bonds are set out in Appendix 28 of this document. SCHEME MEETINGS AND COURT HEARING An opportunity will be given at the Scheme Meetings for Scheme Creditors (including Definitive Holders) to ask any questions and to raise any issues they may have in relation to the Schemes. Provided that the Schemes are approved by the Scheme Creditors at the Scheme Meetings by the requisite statutory majority, Scheme Creditors are also entitled to attend the hearing of the Scheme Companies' applications to the Court to sanction the Schemes which is expected to be heard on 12 to 13 May 2003. Scheme Creditors will be notified of the precise dates of the subsequent steps at the Scheme Meetings to the extent they are then known, and notice of the hearing will be published in certain national daily newspapers, which are expected to be The Times and the international editions of the Wall Street Journal, the Financial Times and the International Herald Tribune. Scheme Creditors who wish to raise any issues in advance of the Scheme Meetings or the Court hearing are encouraged to contact KPMG whose details are set out in Appendix 23. VALUE OF A SCHEME CREDITOR'S SCHEME CLAIM FOR VOTING PURPOSES For the purpose of valuing a Scheme Claim for voting purposes, all Scheme Claims will be converted to sterling at the Voting Rate (which should not be confused with the Scheme Rate, which is used for valuing Scheme Claims to be Admitted under the Schemes). The amount of the Scheme Claim admitted by the relevant Scheme Company for voting purposes does not (of itself) constitute an admission of the existence or amount of any liability of the relevant Scheme Company, and will not bind the relevant Scheme Company, the Supervisors or Scheme Creditors. The value of a Scheme Claim for voting purposes will be taken net of any applicable set-off or cross-claim. The chairman of each Scheme Meeting may, for voting purposes only, reject a Scheme Claim in whole or in part if he considers that it does not constitute a fair and reasonable assessment of the relevant sums owed to the relevant Scheme Creditor by the relevant Scheme Company or if the relevant creditor has not complied with the voting procedures described above. If a claim is for an unliquidated amount or for an amount the quantum of which has not been ascertained and the chairman is able to place a minimum value on a Scheme Claim he will admit it at that value. If a Scheme Claim is disputed in its entirety, whether it is liquidated or unliquidated, the chairman will not admit it. The chairman's decision will be final. The chairman will, however, advise the relevant Scheme Creditor of his decision to reject such Scheme Creditor's claim for voting purposes before the Scheme Meeting if he considers it to be practicable and, in any event, at or after the Scheme Meeting, and report his decision to the Court. The Corp Scheme Meeting will be chaired by Corp's Chairman, John Devaney. Corp's Chief Executive Officer, Michael Parton, will act as his deputy chairman. The plc Scheme Meeting will be chaired by plc's Chairman, John Devaney. plc's Chief Executive Officer, Michael Parton, will act as his deputy chairman. 81

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- C.7 SCHEME CLAIMS AND DISTRIBUTION MECHANICS SCHEME CLAIMS The Schemes will apply to all Liabilities of Corp and plc as at the Record Date other than the Excluded Claims. In the context of making Scheme Claims, the term "SCHEME CREDITOR" in so far as the Bonds are concerned means only the Eurobond Trustee and the Yankee Bond Trustee and does not include any other person with an interest in Bonds. No assignment or transfer of a Scheme Claim (which, in this context in relation to the Bonds, means the claims of the Eurobond Trustee and the Yankee Bond Trustee only) after the Record Date will be recognised for the purposes of determining entitlements under the Schemes, provided that where Corp or plc has received from the relevant parties notice in writing of such assignment or transfer the Supervisors, may, in their sole discretion and subject to the production of such other evidence as they may require and to any other terms and conditions which they may consider necessary or desirable, agree to recognise such assignment or transfer for the purposes of determining entitlements under the Schemes or attendance at any meeting of Scheme Creditors convened after the Effective Date. No assignee or transferee of a Scheme Claim following the Record Date will be entitled to vote at the Scheme Meetings or, save as described above, participate in the relevant Scheme. This paragraph does not affect the trading of Bonds which may be freely traded in the period prior to the date at which Custody Instructions are issued in respect of the relevant Bonds (further details of which are set out in Appendix 28). Any assignor or transferor of a Scheme Claim should provide a copy of this document and any other document issued with or appended to it to any assignee or transferee before the relevant Scheme Claim is assigned or transferred to the assignee or transferee. Corp and plc placed advertisements in The Times and the international editions of the Financial Times, the Wall Street Journal and the International Herald Tribune on Thursday, 19 September 2002. These advertisements explained that Corp and plc proposed to restructure their debt through schemes of arrangement under section 425 of the Act and requested anyone who might have a claim against Corp or plc (or both) to contact KPMG by no later than 5.00 p.m. London time on Friday, 11 October 2002 with details of their claim (whether an actual claim or a contingent one). These advertisements were repeated on 30 January 2003 requesting anyone who might have a claim against Corp or plc (or both) to contact KPMG without delay with details of their claim (whether an actual claim or a contingent one). Corp and plc have written to those of their Known Creditors whose Scheme Claims will be compromised by the proposed schemes of arrangement, with the exception of certain financial creditors with Known Claims who have been represented in negotiations with Corp and plc regarding the development of the Restructuring, creditors for unclaimed interest and redemptions of loan notes issued by Corp whose potential claims are easily quantified and are provided for in full, and those whose addresses Corp and plc have been unable to ascertain. These letters requested the recipients to respond to KPMG within 21 days of the date of the letter submitting details of any claims (whether actual or contingent claims) that they have against Corp or plc or both. With the exception of two clearly frivolous claims, this process identified only one claim against plc, and no claims against Corp, in each case which had not previously been identified by the due diligence undertaken by Corp and plc. The one claim identified is disputed by plc, but is provided for in full in the plc Scheme. EXCLUDED CREDITORS The Schemes provide for certain types of creditor to be excluded from the Schemes. These creditors will be unaffected by the Schemes and are expected to be paid in the ordinary course. FURTHER DETAILS OF THE TYPES OF CLAIMS BEING EXCLUDED FROM THE SCHEMES, AND THE REASONS WHY SUCH CLAIMS ARE BEING EXCLUDED, ARE SET OUT IN APPENDIX 9. The claims of certain creditors have been excluded from the Corp Scheme for a variety of reasons, as follows: a. that Corp will continue to carry on business as the holding company of a very substantial group of companies, comprising some 300 subsidiaries, with an aggregate turnover, in the six months ended 82

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- 31 December 2002, of approximately L1.5 billion and it is necessary to exclude such claims to ensure the continuing viability of the restructured Group -- those categories which are attributable (in whole or in part) to the continuation of the restructured Group are categories 1, 2, 3, 4, 5, 6, 7, 8, 11, 15 and 16; b. that the only type of scheme which Corp's principal financial creditors are prepared to support is a scheme which involves an immediate distribution calculated by reference to specific reserves; and an immediate distribution which consists of the whole amount to which, when calculated by reference to those specific reserves, an admitted scheme creditor is entitled -- the categories which are attributable (in whole or in part) to the nature of the proposed Scheme are categories 2, 3, 4, 5, 9, 17 and 18; c. that certain claims would be preferential if Corp were to be wound up -- the categories which are attributable (in whole or part) to the preferential nature of the claims comprised in them are categories 1, 2 and 10; d. that certain claims would, or might, be incapable of being compromised by means of a scheme -- the category which is attributable (in whole or part) to the inability to compromise obligations is category 2; e. that certain claims would, unless excluded, form a separate class which it would be impractical to consult on that basis -- the categories which are attributable (in whole or in part) to impractical class problems are categories 9 and 14; f. that there are certain claims which it would be uneconomic to include -- the categories which are attributable (in whole or in part) to the costs of including them are categories 13 and 14; and g. that certain claims relate to parties who are assisting in the consideration, negotiation and/or implementation of the Corp Scheme -- the category which is attributable (in whole or in part) to the implementation of the Corp Scheme is category 12. The plc Scheme seeks to exclude the following types of claim: a. contracts that will be novated to Corp or claims that will be settled -- the categories which are attributable (in whole or in part) to this are categories 1 and 9; b. claims that would be preferential if plc were to be wound up -- the categories which are attributable (in whole or part) to the preferential nature of the claims comprised in them are categories 2 and 3; c. claims that would, or might, be incapable of being compromised by means of a scheme -- the category which is in part attributable to this being incapable of compromise is category 2; d. claims that would, unless excluded, form a separate class which it would be impractical to consult on that basis -- the category which is attributable to impractical class problems is category 4; e. claims which it would be uneconomic to include -- the category which is attributable to the cost of including them is category 8; and f. claims that relate to parties who are assisting in the consideration, negotiation and/or implementation of the plc Scheme -- the categories which are attributable (in whole or in part) to assisting in the implementation of the plc Scheme are categories 5, 6, 7 and 9. (Further explanation of the reasons for excluding these categories of claims is set out in Appendix 9). The following obligations of plc have been novated to Corp (conditionally upon the Corp Scheme becoming effective) and will be excluded from the Corp Scheme: a. a guarantee provided to Finmeccanica SpA as the purchaser of certain Italian subsidiaries sold by the Group in 2002; 83

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- b. certain agreements between plc and BAE in respect of the merger of the Group's former defence business with BAE; and c. a licence agreement dated 1 December 1999 between Lemelson Medical, Education and Research Foundation, Limited Partnership and plc. In addition, the service contracts and letters relating to retirement benefits (including FURBS) of Michael Parton and Michael Donovan have been novated to Corp unconditionally. These obligations will also be excluded from the compromise to be effected by the Corp Scheme and will therefore be unaffected by the Corp Scheme. CLAIMS WHICH HAVE THE BENEFIT (IN WHOLE OR IN PART) OF INSURANCE Corp Scheme The Corp Scheme excludes liabilities of Corp to third parties which are covered by a Corp Insurance Policy or which would be covered by a Corp Insurance Policy but for: a. any excess, deductible or limit of liability applicable under any Corp Insurance Policy to any such liability; or b. any insurer failing to satisfy any Corp Insurance Policy claim in full when payable when the insurer is in liquidation or provisional liquidation or administration under the Insolvency Act 1986 or subject to any scheme of arrangement entered into by it under section 425 of the Act (or any equivalent or analogous proceeding or arrangement in any other jurisdiction, including any proceeding under chapter 11 of the Bankruptcy Code); or c. the Corp Insurance Policy or any claim under it being void or avoided by any insurer, being liabilities of Corp in respect of which the third party would have rights against the insurer under that insurance by virtue of Section 1 of the 1930 Act in the event that any of the events set out in section 1(1)(b) of the 1930 Act occurred with respect to Corp. For further details see Appendix 9. ANY CREDITOR WHO IS IN ANY DOUBT AS TO WHETHER THEIR CLAIM MAY BE EXCLUDED UNDER THIS CATEGORY SHOULD SUBMIT A CLAIM FORM IN THE CORP SCHEME WITHOUT DELAY. plc Scheme Liabilities of plc to third parties which are covered by any contract of liability insurance will be treated as a Scheme Claim. However, in the circumstances explained in the next paragraph, such a Scheme Claim may be partially (or wholly) covered by a contract of liability insurance and plc may recover sums from its insurers (or from a compensation scheme which makes a payment to plc where the relevant insurer has become insolvent) in respect of all or part of that claim. Any such sums recovered will be held on trust for the relevant plc Scheme Creditor. The right to receive such sums recovered by plc applies in circumstances in which, and to the extent that, plc's rights against the insurer in respect of the liability constituted by the Scheme Claim would be transferred to and vest in the Insured Scheme Creditor pursuant to the 1930 Act in the event of a winding up order against plc. The rationale for treating these claims in this way is that the liabilities are covered (in whole or in part) by a third party insurer in circumstances where plc's rights against the insurer in respect of its liability to the third party concerned would be transferred in whole or part to, and vest in, the third party by virtue of the 1930 Act if plc were to enter into an insolvency proceeding under the Insolvency Act 1986. Rights equivalent to those which third parties would have under the 1930 Act are provided in the Scheme in order to ensure that creditors who would be protected by the 1930 Act would not be better off by plc entering into an insolvency proceeding under the Insolvency Act 1986 and so constitute a separate class of creditors. 84

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- The only claim of which plc is currently aware and which is covered by insurance in circumstances in which an additional payment might potentially become payable would be any liability that plc may be held to have in respect of the Tri-Star Claim. If liability in respect of the relevant Scheme Claim is established and such liability appears to the Supervisors to be wholly or partly covered by a plc Insurance Policy, the Supervisors will: a. notify the relevant Scheme Creditor of the extent to which it appears that the claim is covered by a plc Insurance Policy (an "Insured Scheme Claim"); and b. at the expense of the relevant Scheme Creditor, use reasonable endeavours to enforce for the benefit of the relevant Scheme Creditor all rights of recovery against an insurer in relation to that Insured Scheme Claim. A Distribution of Scheme Consideration in respect of that Insured Scheme Claim will only be payable once the outcome of such enforcement is known and only to the extent that the net proceeds of enforcement against the insurer held on trust for the relevant Scheme Creditor are less than the amount which appears to the Supervisors to be an Insured Scheme Claim. FOR THE AVOIDANCE OF DOUBT CREDITORS OF PLC WHO MAY HAVE RIGHTS UNDER THE 1930 ACT SHOULD SUBMIT A CLAIM FORM FOR THE FULL AMOUNT OF THEIR CLAIM WITHOUT DELAY. KNOWN CLAIMS AND RESERVE CLAIMS During the Restructuring negotiations it became clear that the principal financial creditors of Corp and plc would only support schemes of arrangement that established a first fixed dividend to be payable to all Scheme Creditors by way of an Initial Distribution on the Effective Date of the Schemes. In order to set the level of that Initial Distribution, Corp and plc have undertaken extensive due diligence to identify all creditors of Corp and plc. The advertising process undertaken by Corp and plc before launching the Schemes sought to ensure that as far as possible all Scheme Creditors were identified and have been included in the schedule of all Known Claims. The provisions set out in the schedule of Known Claims have been set at 100 per cent. or, where the extent of the liability is unclear, on an estimated worst-case scenario basis. In addition to the Known Claims both Schemes include reserves that the Scheme Companies are satisfied will cover any other Scheme Claims that had not been identified by the Record Date (the "RESERVE CLAIMS") and the Prospective Supervisors have confirmed that they have no reason to disagree with this view. However, as outlined above, neither Scheme Company will proceed with its Scheme if either: a. the relevant Scheme Company does not deliver the Scheme Company Confirmation to the Prospective Supervisors on the calendar day prior to each Confirmation Date confirming that the relevant Scheme Company remains satisfied that the level of reserves will be sufficient to ensure the same level of distribution will be made to all relevant Scheme Creditors and, in the case of Corp, that its statement as to the Corp Group's working capital contained in Part D.21 of this Section remains valid; or b. the relevant Scheme Company does not receive the Prospective Supervisor's Confirmation by 7:00 a.m. on each Confirmation Date. The Known Claims against Corp and plc as at the Record Date are listed in Schedule 3 to the Corp Scheme and Schedule 3 to the plc Scheme respectively, set out in parts II and III of this document respectively. The fact that a claim has been provided for in the list of Known Claims at a certain amount does not mean that the particular claim will be Admitted as a Scheme Claim at that, or any other, amount. In particular, where the claim is currently in dispute or the subject of litigation proceedings, the amount included in the Schedules only represents what the relevant Scheme Company considers to be the maximum amount of the claim, which may be disputed in whole or in part and in no way constitutes any admission by the Scheme Company, the Prospective Supervisors, the Supervisors or KPMG that a person with such a claim is a Scheme Creditor or that a liability is owed to any person in respect of any claim or right. 85

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- At the Court hearing to sanction the relevant Scheme, the relevant Scheme Company will present to the Court a schedule of Scheme Claims compiled by the Prospective Supervisors which will set out the details of the Scheme Creditors with Known Claims which are proposed to be Admitted by the Supervisors on the Effective Date and which, in accordance with the terms of the relevant Scheme, will receive their Initial Distribution through the First Initial Distribution. THE KNOWN CLAIMS SEGMENT AND THE RESERVE CLAIMS SEGMENT In relation to each of the Corp and plc Schemes a portion of the Scheme Consideration (the "KNOWN CLAIMS SEGMENT") will initially be set aside to meet the Initial Distribution payable to the Known Creditors in respect of Admitted Known Claims. The remaining portion of the Scheme Consideration (the "RESERVE CLAIMS SEGMENT") will initially be set aside to meet the Initial Distribution payable to the Reserve Creditors in respect of Admitted Reserve Claims. Save as set out below, Reserve Creditors will not be entitled to participate in the distribution to be made out of the Known Claims Segment and will only be entitled to be paid their entitlement to the Scheme Consideration out of the Reserve Claims Segment. The quantum of Reserve Claims that could be met out of the Reserve Claims Segment in each of the Corp Scheme and the plc Scheme is greater than the actual quantum of Known Claims that are expected to be Admitted in that Scheme after deducting or discounting Known Claims in respect of: a. financial creditors; b. landlords; c. intra-group creditors; and d. one disputed claim for a large but unspecified amount that has already been tried by a judge in the US and ruled against on all counts, but is pending appeal. Given the level of due diligence that has been undertaken, Corp and plc are satisfied that they have identified the claims of all financial creditors, landlords and intra-group claims and all disputed claims which have no merit. Accordingly, the level of the reserves would be sufficient to cover more than a 100 per cent. increase in the level of other claims against each Scheme Company. It is currently anticipated that the Known Claims Segment and the Reserve Claims Segment for each of the Schemes will, at the Effective Date, comprise the elements of Scheme Consideration as set out in the tables below (assuming no increase in the cash element of the Corp Scheme Consideration but that the plc Scheme becomes effective on the same day as the Corp Scheme). These figures, which are for illustrative purposes only, assume that each of the Known Claims is Admitted to the relevant Scheme in the full sterling amount listed in Schedule 3 to the relevant Scheme, calculated by applying, where necessary for currency conversion, the Voting Rate. CORP SCHEME <Table> <Caption> Known Reserve Claims Claims Segment Segment ------------- ------------- <S> <C> <C> Cash L 333,360,148 L 8,024,527 Principal amount of New Senior Notes (sterling equivalent) L 441,505,803 L 10,627,771 Principal amount of New Junior Notes (sterling equivalent) L 302,103,439 L 7,272,127 Number of New Shares available for Corp Scheme Creditors 976,218,386 23,499,184 </Table> 86

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- PLC SCHEME <Table> <Caption> Known Reserve Claims Claims Segment Segment ----------- ----------- <S> <C> <C> Cash L44,235,292 L2,361,519 Principal amount of New Senior Notes (sterling equivalent) L68,159,845 L3,638,741 Principal amount of New Junior Notes (sterling equivalent) L46,638,851 L2,489,834 Number of New Shares available for plc Scheme Creditors 150,708,991 8,045,661 </Table> For the purposes of calculating the above table Known Claims that are denominated in a currency other than sterling and New Junior Notes that will be issued by reference to a US dollar amount have been converted at the Voting Rate. The final calculations as to Known Claims will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). The final calculations as to the principal amounts of the New Senior Notes and the New Junior Notes will be made at the Currency Rate (which will be set the Business Day before the Corp Scheme Meeting). The calculation of the Known Claims Segment and the Reserve Claims Segment under the plc Scheme is based upon Ancrane's aggregate claims under the Corp Scheme of approximately L776 million being Admitted (which is expected to occur) and the sum of L7,000,000 being set aside from the cash element of the Corp Scheme Consideration received via Ancrane on account of plc's Ongoing Costs. If a Known Claim is rejected or reduced by the Supervisors in either Scheme then that portion of the Known Claims Segment that would have been used to satisfy that Known Claim (or part thereof) had it been Admitted will be added to the Reserve Claims Segment, unless (in the case of the Corp Scheme only) that Known Claim (or part thereof) is greater than L250,000,000, in which case the relevant portion of the Known Claims Segment will be distributed promptly to all Admitted Scheme Creditors. If a Known Claim is Admitted in an amount higher than the amount set out in Schedule 3 to the Corp Scheme or the plc Scheme set out in parts II and III of this document respectively, the excess over the amount set out in the Schedules to the Corp Scheme and plc Scheme set out in parts II and III of this document respectively will be treated as an Admitted Reserve Claim. THE WAITING PERIOD The segregation of the Known Claims Segment and the Reserve Claims Segment will continue for a period of twelve months from the Effective Date or such shorter period as the Supervisors may determine in accordance with the terms of the Schemes, known as the "WAITING PERIOD". On the expiry of the Waiting Period, all Scheme Consideration remaining in both the Known Claims Segment and the Reserve Claims Segment that has not been distributed to satisfy Known Claims or Reserve Claims (as the case may be) will be held by the Supervisors to meet any Scheme Claims which have not been Admitted or to make Further Distributions to all Scheme Creditors as described below. Accordingly, only Scheme Claims which are Admitted during the Waiting Period will be met out of either the Known Claims Segment or the Reserve Claims Segment (as the case may be). If at any stage after the Effective Date the Supervisors receive notice of a Reserve Claim which: a. if it is immediately Admitted in whole or in part would result in the Supervisors considering that the Reserve Claims Segment of the relevant Scheme will not be sufficient to meet the distributions that are likely to be payable to all Reserve Creditors in respect of Admitted Reserve Claims of that Scheme; and b. the Supervisors cannot immediately determine whether or not, or the extent to which, that Reserve Claim should be Admitted, the Supervisors may consider that Reserve Claim for a period of up to 30 Business Days from the date on which that claim is submitted. On, or prior to, the expiry of this period, the Supervisors will confirm to the relevant Scheme Company and the Creditors' Committee constituted under the terms of the relevant Scheme whether or 87

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- not they consider that the Reserve Claims Segment will not be sufficient to ensure that all Reserve Creditors receive the same level of distribution as those creditors participating in the First Initial Distribution in respect of Admitted Reserve Claims of that Scheme. If, after such consideration, the Supervisors are not satisfied that the Reserve Claims Segment will be sufficient to meet distributions that are likely to be payable to all Reserve Creditors in respect of Admitted Reserve Claims of that Scheme, the Supervisors will be required to bring the Waiting Period to an end. No distributions will be made under the relevant Scheme whilst such a Reserve Claim is being considered by the Supervisors. Following the expiry or termination of the Waiting Period all remaining Scheme Consideration will be held by the Supervisors: a. to make pro rata distributions in accordance with normal English liquidation principles to all Admitted Scheme Creditors who had not received their Initial Distribution at the time that the Waiting Period terminated until they have received the same rateable distribution which other Admitted Scheme Creditors have already received; and b. to make Further Distributions to all Scheme Creditors with Admitted Scheme Claims in accordance with normal English liquidation principles. THE INITIAL DISTRIBUTION In relation to each of the Schemes each Admitted Scheme Creditor will be entitled to receive a proportion of the Scheme Consideration by way of an Initial Distribution calculated in accordance with the following formula: <Table> <S> <C> AC --- X KCS where KC </Table> AC = the quantum of the relevant Scheme Creditors' Admitted Scheme Claim in the relevant Scheme. KC = the aggregate quantum of the Known Claims of the relevant Scheme. KCS = the elements of Scheme Consideration forming the Known Claims Segment of the relevant Scheme. Subject to the expiry or earlier termination of the relevant Waiting Period, Known Claims will be paid out of the Known Claims Segment and Reserve Claims will be paid out of the Reserve Claims Segment of the relevant Scheme. Any Scheme Claim which at the Record Date is not immediately due and payable but would be legally due and payable on an insolvent liquidation of the relevant Scheme Company shall be treated for the purposes of Distributions under the Schemes as immediately due and payable as at the Record Date (and hence not a debt payable at a future time). Any Scheme Claim that is denominated in a currency other than sterling will be converted into sterling at the Scheme Rate. WORKED EXAMPLES CORP SCHEME Accordingly, a Scheme Creditor with an Admitted Scheme Claim of L1,000,000 against Corp would be entitled to receive (assuming no increase in the cash element but that the plc Scheme becomes effective on the same day as the Corp Scheme) an Initial Distribution out of the Known Claims Segment (or the Reserve Claims Segment, as appropriate) in the Corp Scheme of approximately: <Table> <S> <C> <C> 1,000,000 ------------- X KCS 5,192,831,052 = 0.000192573 X KCS </Table> 88

For the purposes of calculating the above table Known Claims that are denominated in a currency other than sterling and New Junior Notes that will be issued by reference to a US dollar amount have been converted at the Voting Rate. The final calculations as to Known Claims will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). The final calculations as to the principal amounts of the New Senior Notes and the New Junior Notes will be made at the Currency Rate (which will be set the Business Day before the Corp Scheme Meeting). PLC SCHEME Similarly, a Scheme Creditor with an Admitted Scheme Claim of L1,000,000 against plc would be entitled to receive (assuming no increase in the cash element of the Corp Scheme Consideration but that the plc Scheme becomes effective on the same day as the Corp Scheme) an Initial Distribution out of the Known Claims Segment (or the Reserve Claims Segment, as appropriate) in the plc Scheme of: <Table> <S> <C> <C> 1,000,000 = ------------- X KCS 4,682,928,026 = 0.000213542 X KCS </Table> Rounding down fractional entitlements, the plc Scheme Creditor would be entitled to receive approximately: <Table> <S> <C> <C> <C> <C> 0.000213542 X L44,235,292 cash = L9,446 cash 0.000213542 X L68,159,845* New Senior Notes = L14,554* New Senior Notes 0.000213542 X L46,638,851* New Junior Notes = L9,959* New Junior Notes 0.000213542 X 150,708,991 New Shares = 32,182 New Shares </Table> --------------- * equivalent principal amount If the plc Scheme does not become effective on the same day as the Corp Scheme the Corp/plc distribution model described under the heading "Circulation of Scheme Consideration and payments on a modelled basis" below will not have been applied, and accordingly each of the numbers set out above will be reduced by approximately 8.51 per cent. For the purposes of the above calculations, Known Claims that are denominated in a currency other than sterling and the New Junior Notes that will be issued by reference to a US dollar amount, have been converted at the Voting Rate. The final calculations as to Known Claims will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). The final calculations as to the principal amounts of the New Senior Notes and the New Junior Notes will be made at the Currency Rate (which will be set the Business Day before the Corp Scheme Meeting). 89

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- The First Initial Distribution The Corp Scheme provides for a First Initial Distribution to be made on the Effective Date to all Scheme Creditors whose Scheme Claims have been submitted to the Prospective Supervisors by the First Claim Date and whose claims have been approved to be Admitted by the Prospective Supervisors by 8.00 a.m. on the first day of the Court hearing to sanction the Corp Scheme. At the time of making the First Initial Distribution in respect of Known Claims the Supervisors will set aside from the Known Claims Segment the proportion of the Scheme Consideration that would be payable to Known Creditors in respect of which a Claim Form either has not been Submitted or where a Claim Form has been Submitted but which has not been Admitted by the Supervisors by the date of the First Initial Distribution. Similarly, at the time of making the First Initial Distribution in respect of Reserve Claims the Supervisors will set aside from the Reserve Claims Segment the proportion of the Scheme Consideration that would be payable to Reserve Creditors in respect of which a Claim Form has been Submitted but which has not been Admitted by the Supervisors by the date of the First Initial Distribution. If such claims are subsequently Admitted, in whole or in part, the relevant Scheme Creditors will receive the portion of the Scheme Consideration held on account of their claims by way of an Initial Distribution as soon as practicable after the Scheme Claim is Admitted. If a Known Claim is rejected or reduced by the Supervisors in either Scheme then that portion of the Known Claims Segment that would have been used to satisfy that Known Claim (or part thereof) had it been Admitted will be added to the Reserve Claims Segment, unless (in the case of the Corp Scheme only) that Known Claim (or part thereof) is greater than L250,000,000, in which case the relevant portion of the Known Claims Segment will be distributed to all Admitted Scheme Creditors pro rata to their entitlements under the Corp Scheme, all in accordance with the terms of the Corp Scheme. SCHEME CREDITORS WILL NOT BE ENTITLED TO DISTURB ANY PREVIOUS DISTRIBUTION FOR ANY REASON, INCLUDING BY REASON THAT SUCH SCHEME CREDITORS HAVE NOT PARTICIPATED IN IT. As mentioned above, if, contrary to expectations, at any time after the First Initial Distribution the Supervisors are no longer satisfied that the Reserve Claims Segment will be sufficient to meet the distributions to be made to all Reserve Creditors, then the Waiting Period for that Scheme will be brought to an end and all Further Distributions to Scheme Creditors will be made on a strictly pari passu basis. ADMISSION AND COMPROMISE OF SCHEME CLAIMS In order to claim their entitlement to Scheme Consideration, Scheme Creditors will be required to submit a duly completed Claim Form. A form of Claim Form is set out in Appendix 30. The relevant Claim Form should be completed in accordance with the instructions set out in Appendix 27. No person (other than the Trustees) with an interest in Bonds is required to submit Claim Forms but Account Holders will be required to deliver Account Holder Letters to Bondholder Communications before 5.00 p.m. (New York City time) on 17 April 2003 in accordance with the instructions set out in Appendix 28 so that Scheme Consideration (other than cash comprised in the First Initial Distribution and attributable to Bondholders in respect of Eurobonds) can be distributed to Designated Recipients in the First Initial Distribution. The Claim Forms in respect of the Bonds will be submitted by the respective Trustees. Once completed the relevant Claim Form should be submitted to the Prospective Supervisors, 8 Salisbury Square, London EC4Y 8BB, England, UK, for the attention of Philip Wallace and Richard Heis, or, following the Effective Date, to the Supervisors (at the address shown in Appendix 23). Scheme Creditors are encouraged to submit their Claim Forms as soon as possible (ideally, Claim Forms should be submitted at the same time as Forms of Proxy). Once a Scheme Creditor has submitted a duly completed Claim Form the Claim Form will be reviewed by the Prospective Supervisors and, subject to the relevant Scheme becoming effective, its claim will be adjudicated by the Supervisors (see "Procedure for the admission and rejection of claims" below). Provided the relevant Scheme becomes effective all Scheme Claims will be fully and completely released on the earlier of the date on which a Scheme Claim is Admitted and is the subject of a Distribution Notice, the Final Distribution Date and the Termination Date. In consideration of the release of its Scheme Claim the relevant 90

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Scheme Creditor will become entitled to be paid and issued with its entitlement to Scheme Consideration in accordance with the terms of the relevant Scheme. The claims of Bondholders will be dependent upon the relevant Trustee submitting a Claim Form to the Supervisors in respect of the relevant Bond issue and the Supervisors Admitting that Claim. SUPERVISORS The Schemes provide for the appointment of Supervisors who will be responsible for evaluating the claims of Scheme Creditors and generally administering the Schemes. The Supervisors must be individuals qualified to act as insolvency practitioners within the meaning of the Insolvency Act 1986. The Supervisors are entitled to exercise their functions and powers jointly and severally. In carrying out their functions and exercising their powers, under the Schemes, the Supervisors will be entitled to consult with the Creditors' Committee. Prior to the Schemes becoming effective, the Prospective Supervisors have undertaken to use reasonable endeavours to determine promptly whether and if so, the extent to which, a Scheme Claim which has been submitted in a duly completed Claim Form will be listed in the Prospective First Initial Distribution Notice. On a Scheme becoming effective Scheme Claims listed in the Prospective First Initial Distribution Notice for that Scheme will be Admitted by the Supervisors, giving rise to an entitlement to a First Initial Distribution. More detail concerning the procedure for admitting Scheme Claims is set out below under the heading "Procedure for the admission and rejection of claims". The Schemes require the Supervisors, on and from the Effective Date, to use reasonable endeavours to determine promptly whether and if so, the extent to which, a Submitted Scheme Claim will be Admitted and, if so, to promptly Admit that Scheme Claim. Corp and plc have entered into a letter agreement appointing Philip Wallace and Richard Heis as the first Supervisors in accordance with the terms of the Schemes. The curricula vitae of the Supervisors appear in Appendix 23. The terms of the letter agreement are summarised in Appendix 24. The material interests of the Supervisors are set out in Appendix 23. PROCEDURE FOR THE ADMISSION AND REJECTION OF CLAIMS The Supervisors will adjudicate Scheme Claims to decide whether or not they should be Admitted. If and to the extent that the Supervisors are satisfied with the information provided by a Scheme Creditor on a Claim Form the Supervisors will admit the Scheme Claim as an Admitted Scheme Claim and notify the Scheme Creditor accordingly. If the Supervisors are not satisfied with the information provided by a Scheme Creditor on a Claim Form the Supervisors are entitled to call for additional evidence to be provided in support of the Scheme Claim. Creditors with disputed Scheme Claims will receive their entitlement to the Scheme Consideration to the extent and in the amount that the dispute is resolved in their favour and their Scheme Claim is Admitted. If and to the extent that the Supervisors are not satisfied that the Scheme Claim should be Admitted they will reject the Scheme Claim and notify the Scheme Creditor accordingly. If a Scheme Creditor is dissatisfied with the decision of the Supervisors with respect to its Scheme Claim it may either commence or continue proceedings against the relevant Scheme Company to secure the determination of the quantum of its Scheme Claim or elect by notice in writing to the Supervisors that the existence or quantum of its Scheme Claim be referred for adjudication to an independent third party. If such proceedings have not previously been commenced, any proceedings to determine the amount of a Scheme Claim must be commenced or a notice to elect for adjudication made within 40 Business Days following receipt by the Scheme Creditor of the notice of rejection. If no such proceedings are commenced or election for adjudication made within that 40 Business Day period, the relevant Scheme Company will be released from all liability in relation to that Scheme Claim (or part thereof) which has been rejected and no further proceedings in relation to that Scheme Claim will be permitted. The Schemes do not affect the right of a Scheme Creditor to bring proceedings against Corp or plc only to establish the existence or amount of his Scheme Claim, as appropriate, in the courts of any jurisdiction or according to any law (subject to any other provisions determining governing law and jurisdiction, whether contained in any contract between either Corp and/or plc and the Scheme Creditor or otherwise) provided that the 91

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Scheme Creditor has first given the Supervisors five Business Days' prior notice in writing of its intention to bring proceedings and, if the Scheme Creditor wishes to bring proceedings upon receipt of a notice from the Supervisors rejecting its Scheme Claim, those proceedings must be brought within 40 Business Days following receipt by the Scheme Creditor of the notice of rejection. The exercise of all other rights and remedies of Scheme Creditors against the relevant Scheme Companies in respect of Scheme Claims are prohibited by the Schemes. The Prospective Supervisors will undertake a review of all Claim Forms submitted prior to the Effective Date to determine whether the Scheme Claims can be properly Admitted on the Effective Date and, provided the relevant Claim Form was submitted prior to the First Claim Date, whether the relevant Scheme Claim will be included in the First Initial Distribution. THE ESCROW TRUSTEE AND THE DISTRIBUTION AGENT The Schemes also provide for the appointment of an Escrow Trustee who will hold the Scheme Consideration on trust for the Scheme Creditors and a Distribution Agent who will be responsible for the distribution of the Scheme Consideration to the Scheme Creditors with Admitted Scheme Claims. Corp and plc have entered into an agreement appointing Corp SPV as the first Escrow Trustee and The Bank of New York as the first Distribution Agent in accordance with the terms of the Schemes and subject to the relevant Scheme becoming effective. A copy of the agreement is set out in Appendix 7. On the issue by the Supervisors of the notice in respect of the First Initial Distribution, Corp will transfer, issue and allot the Scheme Consideration together with the plc Shareholder Stock to or to the order of the Escrow Trustee to be held on trust for the Corp Scheme Creditors and the plc Shareholders respectively. The Distribution Agent will hold the New Notes and any cash comprised in the Scheme Consideration as custodian for the Escrow Trustee. The New Shares will be registered in the name of the Escrow Trustee or its nominee. The Scheme Consideration (together with any income accrued on it in accordance with the Escrow and Distribution Agreement) will be distributed by the Distribution Agent (acting on the instructions of the Supervisors and the Escrow Trustee) to, and at the direction of, the Scheme Creditors with Admitted Scheme Claims (taking into consideration the cost of making the distribution and the amount of Scheme Consideration to be distributed) as soon as practicable after the relevant Scheme Claim has been Admitted, together with any interest accrued and principal repaid on New Notes, any interest accrued on any cash balances and dividends paid on New Shares in respect of that portion of Scheme Consideration. The Escrow and Distribution Agreement contains a direction by the Eurobond Trustee and the Yankee Bond Trustee to the effect that any Scheme Consideration attributable to the Bonds should be distributed in accordance with the directions contained in the Account Holder Letters to be submitted to Bondholder Communications by Account Holders. To the extent that Account Holder Letters are not received by 5.00 p.m. (New York City time) on 17 April 2003 and accordingly any Scheme Consideration attributable to the Scheme Claims made by the Trustees is not distributed in the First Initial Distribution, the Escrow Trustee will continue to hold such undistributed Scheme Consideration in accordance with the directions of the relevant Trustee. The Eurobond Trustee has directed that any Scheme Consideration attributable to its Scheme Claim which has not been distributed by the end of the Waiting Period should be held by the Escrow Trustee pending the Eurobond Trustee obtaining instructions from the holders of the relevant Eurobonds (by way of an Extraordinary Resolution) or, if appropriate, directions from the Court. The Escrow Trustee has undertaken not to exercise any voting rights attaching to the New Shares or the New Notes while they are held in escrow as referred to above. The arrangements under which the Escrow Trustee holds the Scheme Consideration on trust for Scheme Creditors are expected to constitute a bare trust, in which case the Escrow Trustee will be required to deduct tax at the basic rate (currently 22 per cent.) from any interest or dividends received in respect of the Scheme Consideration before paying the remainder to Scheme Creditors as part of their distribution. If the arrangements are, for any reason, held not to constitute a bare trust, there may be additional taxes payable by the Escrow Trustee in respect of the Scheme Consideration that does not form part of the First Initial Distribution. Corp has agreed to set aside certain amounts to be paid towards any tax liability of the Escrow Trustee. Any additional amounts will, in the first instance, be met out of the Reserve Claims Segment or, after the expiry of the Waiting 92

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Period, out of the combined Reserve Claims Segment and Known Claims Segment. If the Supervisors terminate the Waiting Period on the grounds that the Reserve Claims Segment may not be sufficient to meet the claims of all Reserve Creditors, any tax costs will cease to be met out of the Reserve Claims Segment, and any distributions made thereafter will be made subject to a withholding on account of all taxes which would be payable by the Escrow Trustee in respect of that distribution. Corp has agreed to indemnify the Escrow Trustee against any tax liability which cannot be met as described above. The Escrow Trustee has agreed to seek confirmation from the Inland Revenue (as soon as reasonably practicable after the Effective Date of the Corp Scheme and, in any event, before the end of the Waiting Period) that the arrangements will be taxed as a bare trust. Pending any confirmation from the Inland Revenue to the contrary, or any indication by the Inland Revenue that such confirmation will not be given until a later date (such as the submission of a tax return by the Escrow Trustee), the Escrow Trustee will operate the arrangements on the basis that they constitute a bare trust. CIRCULATION OF SCHEME CONSIDERATION AND PAYMENTS ON A MODELLED BASIS Corp has the benefit of a Scheme Claim of L146,587,439 against plc. Accordingly, Corp will submit a Claim Form pursuant to the plc Scheme and, if the plc Scheme becomes effective and Corp's claim is Admitted (which Corp expects to be the case), Corp will become entitled to receive its pro rata entitlement in respect of its Admitted Scheme Claim in the First Initial Distribution under the plc Scheme. Corp has agreed to distribute its entitlement to receive Scheme Consideration under the plc Scheme (or, should the plc Scheme not become effective, its entitlement to any sum of money or property to which it becomes entitled to as a result of its claim against plc) to Corp Scheme Creditors by way of additional Corp Scheme Consideration. Similarly plc has agreed to distribute any of this additional Scheme Consideration it would be entitled to receive from Corp via Ancrane to all plc Scheme Creditors (which will in turn include Corp). To prevent the continued circulation of an ever decreasing amount of additional Scheme Consideration, Ancrane and the Prospective Supervisors of both Schemes (in each case the same two persons) have agreed that, if both Schemes become effective and, as anticipated, the First Initial Distributions under the Schemes are payable on the same date, the Supervisors will agree a distribution model (the "CORP/PLC MODEL") simulating successive distributions under the Corp Scheme and the plc Scheme of amounts distributed to Corp out of the plc Scheme in order to produce a net amount of additional Scheme Consideration available for distribution to Admitted Scheme Creditors under the Corp Scheme and the plc Scheme respectively. For this purpose, no Scheme Consideration will be paid from Corp to Ancrane and arrangements will be made for all Bonds held by Ancrane to be blocked. It is currently anticipated that the amount of any additional Scheme Consideration payable to Admitted Scheme Creditors as a result of this circulation of Scheme Consideration will be paid to Admitted Scheme Creditors when they receive their Initial Distribution. Similar provisions may apply for any Further Distributions made at the same time under each of the Schemes. For example, this may occur at the end of the Waiting Period. The ability of Ancrane to make a repayment of capital in specie to plc has been facilitated by Ancrane having become an unlimited company on 25 March, 2003. Pursuant to the terms of the Scheme Implementation Deed, prior to the Corp Scheme Meeting, Ancrane will effect a reduction of its existing share capital (including its share premium account) and will make a repayment of capital in specie to plc of its assets (other than L100), including any receipt of, or right that it may have to receive, any Corp Scheme Consideration and any plc Scheme Consideration. TREATMENT OF DE MINIMIS CLAIMS The Schemes provide for the claims of all Scheme Creditors who are owed in aggregate less than L5,000 to be excluded from the Schemes. Accordingly it is expected that all such creditors will be paid in full if and when such claims arise. As indicated above, in the context of submitting Scheme Claims the only Scheme Creditors that will be recognised in relation to the Bonds are the two Trustees. Accordingly Account Holders who hold less than L5,000 in principal amount of the Bonds of any series for any Bondholder should still submit an Account Holder Letter in respect of that holding. 93

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- C.8 MEETINGS, FINAL TERMINATION, RELEASE AND GOVERNING LAW CREDITORS' COMMITTEE AND FURTHER MEETINGS OF SCHEME CREDITORS Each of the Schemes provides for a Creditors' Committee of representatives of the Scheme Creditors (which expression, in this context, includes Definitive Holders) to be appointed to monitor the implementation of the relevant Scheme, the actions of the Supervisors and the calling of meetings of Scheme Creditors. Each Creditors' Committee will comprise a minimum of three and a maximum of seven members. The members of the Creditors' Committee will be appointed as described below. The Creditors' Committee will meet at least once every 12 months during the continuation of the Schemes and will receive a report on the progress of the relevant Scheme from the Supervisors. A Scheme Creditor or Definitive Holder who is willing to act as a member of the Creditors' Committee may propose itself to act as a member of the Creditors' Committee by ensuring that the appropriate box on the Claim Form or Account Holder Letter, as the case may be, is ticked. On the Effective Date, the Supervisors will, to the extent possible, appoint up to seven members of the Creditors' Committee selected from those Scheme Creditors and Definitive Holders who have proposed themselves to act, representing a proper balance of interests of Scheme Creditors as a whole. If fewer than three Scheme Creditors and Definitive Holders propose themselves to act as a member of the Creditors' Committee, then on and from the Effective Date the Creditors' Committee will consist of as many members as have proposed themselves to act. In accordance with the terms of the Scheme those members, if any, will endeavour to fill the vacancy or vacancies to ensure that the Creditors' Committee has a minimum of three members within 28 days of the Effective Date. If those members do not succeed in appointing the necessary number of further members of the Creditors' Committee, resulting in a Creditors' Committee consisting of fewer than three members by 28 days after the Effective Date, the Supervisors will thereafter use reasonable endeavours to appoint the necessary number of further members within the following 14 days as interim committee members to serve on the Creditors' Committee until the necessary number of further permanent members are appointed. Meetings of Scheme Creditors will be held at least once every 12 months during the continuation of the Schemes unless the Supervisors and the Creditors' Committee otherwise agree. The Supervisors can call a meeting of Scheme Creditors for any purpose they think necessary in order to keep Scheme Creditors informed about the progress of the Schemes or to obtain their input as regards the function of the Schemes. The Creditors' Committee may convene a meeting of Scheme Creditors to remove or appoint either or both Supervisors or for any other purpose they think fit. In addition, five Scheme Creditors with Scheme Claims in aggregate in excess of fifteen per cent. of all Scheme Claims, or any 20 or more Scheme Creditors may convene a meeting of Scheme Creditors. FINAL TERMINATION PROVISIONS As soon as reasonably practical after the making of the final distributions under each of the Schemes or the Supervisors' determination that any further distribution of Scheme Consideration would be uneconomic (i.e. if the costs of making the distribution would exceed the value of the Scheme Consideration to be distributed (or the proceeds of sale of that Scheme Consideration)), the relevant Supervisors will serve a termination notice on the relevant Scheme Company and the members of the relevant Creditors' Committee. With effect from the date of the termination notice, a. Scheme Creditors, the Creditor's Committee, the relevant Scheme Company, the Supervisors, the Eurobond Trustee, the Yankee Bond Trustee, the Escrow Trustee, the Distribution Agent, the Registrars and Bondholder Communications will have no further rights or obligations under the Scheme except that the compromise of Scheme Claims pursuant to the terms of the Scheme will continue to have effect; and b. the Supervisors (and any former Supervisors) and the members of the Creditors' Committee (and any former members) will be discharged from any liability for their respective acts, omissions and conduct pursuant to or under the Schemes other than any liability arising from their respective 94

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- misfeasance, breach of duty or wilful default or, in the case of the Supervisors, their negligence or that of a partner in or employee of KPMG. RELEASE OF CO-ORDINATION COMMITTEE AND THE INFORMAL COMMITTEE OF BONDHOLDERS Under the Corp Scheme and the plc Scheme the Co-ordination Committee, the Informal Committee of Bondholders and their past and present members and their legal and financial advisers will be released from any Liability which they or any of them may have to a Scheme Creditor, Corp, plc, the Supervisors, the Escrow Trustee, the Distribution Agent, the Eurobond Trustee, the Yankee Bond Trustee, Bondholder Communications and the ESOP Derivative Banks. GOVERNING LAW AND JURISDICTION The Schemes will be governed by and construed in accordance with English law. The Court will have exclusive jurisdiction to hear and determine any suit, action or proceeding and to settle any dispute which may arise out of the Explanatory Statement or any provision of the Schemes, or any action taken or omitted to be taken under the Schemes or in connection with the administration of the Schemes. For such purposes, Scheme Creditors irrevocably submit to the jurisdiction of the Court, subject to the proviso that in relation to the determination of any Scheme Claim the validity of other provisions determining governing law and jurisdiction as between either Corp and/or plc and any of its Scheme Creditors, whether contained in any contract or otherwise, will not be affected. C.9 EFFECT OF SECURITIES LAW RESTRICTIONS UNDER THE SCHEMES GENERAL PRINCIPLES OF THE SCHEMES Securities will not be distributed pursuant to the Schemes to or to the order, or for the account or benefit, of any person where such distribution would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous. Where any determination is (or has been) required as to whether any such conditions or requirements are "unduly onerous", such determination will be (or has been) made by Corp (in connection with distributions pursuant to the Corp Scheme) or plc (in connection with distributions pursuant to the plc Scheme), as the case may be, with the advice of legal counsel and having due regard for the number of Scheme Creditors, Bondholders and/or plc Shareholders that are or may be located in the relevant jurisdiction, the value of the securities to which such persons are or may be entitled pursuant to the Schemes, the extent to which the requirements of the laws and regulations of such jurisdiction as applied to the Schemes are uncertain, the nature and extent of the risks or penalties associated with any violation of those legal or regulatory requirements and the costs, administrative burden and timing implications of taking such action (if any) as might permit distributions of securities to be made in that jurisdiction (including pursuant to any available exemptions) in accordance with applicable legal and regulatory requirements. Any reference in the discussion that follows to whether distribution of securities would be prohibited except after compliance with conditions or requirements that are "unduly onerous" should be construed accordingly. To the extent that securities that would otherwise be deliverable pursuant to the Schemes cannot be delivered because of a legal or regulatory prohibition described above, the persons that would otherwise be entitled to receive such securities will receive cash instead, as follows: a. in the case of Scheme Creditors (other than the Trustees) and Designated Recipients, the Distribution Agent will sell or procure the sale of such securities on the best terms reasonably obtainable at the time of sale and will pay the net cash proceeds of such sale (after deduction of all applicable expenses including any currency conversion costs) to the relevant person in full satisfaction of such person's rights in respect of such securities under the relevant Scheme. Any such sale will be deemed to have been undertaken at the request of the relevant person, and none of Corp, plc, the Escrow Trustee, the Distribution Agent, the Registrars, the Supervisors or any other person will be responsible for any loss arising from the terms or the timing of such sale. If the relevant securities are not listed on a securities exchange, however, the relevant person will receive a sum in cash which is substantially equivalent in value to such securities, such sum to be 95

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- determined by agreement between Corp or plc, as the case may be, and the Supervisors or by adjudication in accordance with the provisions of the relevant Scheme; and b. in the case of plc Shareholders, the Registrars will use reasonable endeavours to sell or procure the sale of such securities on the best terms reasonably obtainable at the time of sale and will pay the net cash proceeds of such sale (if any) to the relevant plc Shareholder in sterling (after deduction of all applicable expenses including any currency conversion costs) in full satisfaction of the rights of such plc Shareholder in respect of such securities under the Corp Scheme. Any such sale will be deemed to have been undertaken at the request of the relevant person, and none of Corp, plc, the Escrow Trustee, the Distribution Agent, the Registrars, the Supervisors or any other person will be responsible for any loss arising from the terms or the timing of such sale or any failure to procure a purchaser for such securities. Any determination made by Corp or plc with respect to legal or regulatory prohibitions on the distribution of securities pursuant to the Schemes will be (or has been) made solely with regard to such laws and regulations as are generally applicable to persons located in the relevant jurisdiction. Such determinations will not take account of any legal or regulatory restrictions that may be applicable to a particular Scheme Creditor, Bondholder, Designated Recipient or plc Shareholder by virtue of any business or other activity conducted by such person in such jurisdiction, or the regulatory status or other relevant legal attributes of such person. Scheme Creditors, Bondholders, Designated Recipients and plc Shareholders are strongly advised to consult their professional advisers as to whether any laws or regulations which may be applicable to them may give rise to any liability or penalty, or require them to obtain any government or other consents or to pay any taxes or duties, as a result of the implementation of the Schemes. None of Corp, plc, the Escrow Trustee, the Distribution Agent, the Supervisors, Bondholder Communications, the Registrars, the Informal Committee of Bondholders, the Co-ordination Committee, their respective directors or any other parties involved in the Restructuring accept any responsibility for any liabilities (including but not limited to consequential liabilities) incurred by Scheme Creditors, Bondholders, Designated Recipients or plc Shareholders as a result of the implementation of the Schemes in respect of laws or regulations applicable to them (except that UK stamp duty or SDRT payable in connection with the issuance of ADRs will be met by Corp to the extent described herein). JURISDICTIONS IN WHICH DISTRIBUTION OF SECURITIES IS NOT RESTRICTED Corp and plc have determined that the distribution of securities pursuant to the Schemes in the following jurisdictions is not currently prohibited by any applicable law or regulation requiring compliance with conditions or requirements that are unduly onerous: a. United Kingdom; b. Bahamas; c. British Virgin Islands; d. Canada (provinces of Alberta, British Columbia, Ontario and Quebec); e. Cayman Islands; f. Guernsey; g. Jersey; h. Netherlands Antilles; and i. United States (with respect to federal securities law and, except as described below, with respect to state securities law). The above-mentioned jurisdictions are sometimes referred to collectively in the discussion that follows as "UNRESTRICTED JURISDICTIONS." 96

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- The Schemes will provide that persons located in Unrestricted Jurisdictions will not be prohibited from receiving distributions of securities pursuant to the Schemes by virtue of any legal or regulatory prohibition of general application under the laws or regulations of such jurisdictions. Notwithstanding the foregoing, securities will not be distributed pursuant to the Schemes to or to the order, or for the account or benefit, of any person in any Unrestricted Jurisdiction if at any time there has been a change of law or regulation since 27 March 2003 (the latest practicable date prior to the date of this document) in such jurisdiction, such that distribution of securities pursuant to the Schemes to a person in such jurisdiction would be prohibited, or so prohibited except after compliance with conditions or requirements that are unduly onerous. JURISDICTIONS IN WHICH DISTRIBUTION OF SECURITIES IS RESTRICTED Corp and plc have determined that the distribution of securities pursuant to the Schemes in the following jurisdictions would be prohibited by applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous, unless the conditions of one or more applicable exemptions from such laws or regulations can be met: a. France; b. Italy; and c. the US states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont. Accordingly, the Schemes will provide that persons located in the above jurisdictions will be prohibited from receiving distributions of securities pursuant to the Schemes, and will receive cash instead as described above, unless the conditions for reliance on an available exemption have been met. Details with respect to certain relevant exemptions covering institutional or professional investors and certain other persons are set out in Part D.16 and Part D.17 of this Section. In addition, Corp and plc have determined that any distribution of securities pursuant to the Schemes to persons in Malaysia is currently prohibited by applicable securities laws or regulations requiring compliance with conditions or requirements that are unduly onerous, and that no exemption from this prohibition will be available. Accordingly, persons located in Malaysia will be prohibited from receiving distributions of securities pursuant to the Schemes, and will receive cash instead as described above. France, Italy, Malaysia and the above-mentioned US states are sometimes referred to collectively in the discussion that follows as "RESTRICTED JURISDICTIONS." Notwithstanding the foregoing, the restrictions on the distribution of securities pursuant to the Schemes with respect to any Restricted Jurisdiction will cease to apply if at any time there has been a change of law or regulation since 27 March 2003 (the latest practicable date prior to the date of this document) in such jurisdiction, such that delivery of securities pursuant to the Schemes to a person in such jurisdiction would no longer be prohibited, or so prohibited except after compliance with conditions or requirements that are unduly onerous. Any such change will not affect the rights of any person that has previously received cash instead of securities pursuant to the Schemes, as described above. In addition, notwithstanding the foregoing, distributions of New Shares and Warrants to plc Shareholders in Restricted Jurisdictions will be restricted only to the extent described below under "Treatment of plc Shareholders in Restricted Jurisdictions." OTHER JURISDICTIONS With respect to any jurisdiction other than an Unrestricted Jurisdiction or a Restricted Jurisdiction named above, the general principles of the Schemes will apply as described above. Accordingly, securities will not be distributed pursuant to the Schemes to or to the order, or for the account or benefit, of any person located in a jurisdiction other than an Unrestricted Jurisdiction or a Restricted Jurisdiction if it should come to the attention of Corp or plc (as the case may be) that such distribution would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous. Neither Corp 97

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- nor plc is currently aware of any such prohibition in any jurisdiction (other than as described above with respect to Restricted Jurisdictions). SECURITIES LAW CONFIRMATIONS IN CLAIM FORM In connection with the legal and regulatory restrictions referred to above and in order to establish the conditions for reliance on certain relevant exemptions from these restrictions, the Claim Form will require the person completing it (other than the Trustees) to confirm that it is not submitting such Claim Form on behalf of, or requesting delivery of any securities to or for the benefit of, any person that is located in: a. France (other than a "qualified investor" as defined in Article L.411-2 of the French Monetary and Financial Code); b. Italy (other than a "professional investor" as defined in the Consolidated Financial Act Article 30, paragraph II and in CONSOB Regulation 11522/1998 Article 31, paragraph II); c. Malaysia; d. the US states of Arizona, California, Colorado, Connecticut, Illinois, Ohio or Vermont (other than a person that is eligible to receive the securities under a relevant exemption as described in Part D.16 of this Section). Persons completing a Claim Form (other than the Trustees) should refer to Part D.17 of this Section (with respect to France, Italy and Malaysia) and to Part D.16 of this Section (with respect to Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont) for information as to the circumstances under which they would be regarded as located in one of these jurisdictions for these purposes, and for details with respect to the various categories of eligible recipients in such jurisdictions under the exemptions referred to above and other relevant information. Such persons should also carefully consider the terms of the confirmations included in the Claim Form set out in Appendix 30. SECURITIES LAW CONFIRMATIONS IN ACCOUNT HOLDER LETTER In connection with the legal and regulatory restrictions referred to above and in order to establish the conditions for reliance on certain relevant exemptions from these restrictions, the Account Holder Letter will require each relevant Account Holder to confirm that it is not submitting such Account Holder Letter on behalf of, or requesting delivery of any securities to or for the benefit of, any person that is located in: a. France (other than a "qualified investor" as defined in Article L.411-2 of the French Monetary and Financial Code); b. Italy (other than, with respect to the plc Scheme, a "professional investor" as defined in the Consolidated Financial Act Article 30, paragraph II and in CONSOB Regulation 11522/1998 Article 31, paragraph II); c. Malaysia; or d. the US states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont (other than a person that is eligible to receive the securities under a relevant exemption as described in Part D.16 of this Section). Account Holders, Bondholders and Designated Recipients should refer to Part D.17 of this Section (with respect to France, Italy and Malaysia) and to Part D.16 of this Section (with respect to Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont) for information as to the circumstances under which they would be regarded as located in one of these jurisdictions for these purposes, and for details with respect to the various categories of eligible recipients in such jurisdictions under the exemptions referred to above and other relevant information. Such persons should also carefully consider the terms of the confirmations included in the Account Holder Letter set out in Appendix 28. 98

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- EFFECT OF SECURITIES LAW CONFIRMATIONS UNDER THE SCHEMES The Schemes will provide that if the required confirmations are given in the form requested in a Claim Form or Account Holder Letter then, except as described below, distribution of the New Shares and New Notes to which such Claim Form or Account Holder Letter (as the case may be) relates will not be prohibited on the basis of any legal or regulatory prohibition of general application under the laws or regulations of any Restricted Jurisdiction. Notwithstanding the foregoing, if it appears from the relevant Claim Form or Account Holder Letter that such confirmations have been given inappropriately then, except as described below with respect to Italy, New Shares and New Notes will not be distributed in respect of such Claim Form or Account Holder Letter, in which case the relevant person or persons will receive cash instead as described above. Confirmations will be deemed to have been given inappropriately if (i) information provided in or in connection with the transmittal of the Claim Form or Account Holder Letter indicates that such Claim Form has been submitted by, or such Account Holder Letter has been delivered on behalf of, or delivery of securities is being requested to or for the account or benefit of, a person that is located in a Restricted Jurisdiction and that could not be eligible to receive the securities under any relevant exemption described in this document or (ii) Corp or plc (as the case may be) obtains actual knowledge that such confirmations are false. Corp and plc reserve the right, in their sole discretion, to investigate in relation to any Claim Form or Account Holder Letter the facts relevant to the confirmations included therein. The determination as to whether confirmations have been appropriately given will be made by Corp (in connection with distributions pursuant to the Corp Scheme) or plc (in connection with distributions pursuant to the plc Scheme), as the case may be. Except as described below with respect to Italy, if the required confirmations are not given in the form requested in a Claim Form or Account Holder Letter, then New Shares and New Notes will not be distributed in respect of such Claim Form or Account Holder Letter, in which case the relevant person or persons will receive cash instead as described above. Notwithstanding the foregoing, to the extent that Corp or plc determines that the exemptions applicable with respect to distributions of securities to limited numbers of persons are available in Italy, securities will be distributed to the relevant persons without regard to the confirmations given in any relevant Claim Form or Account Holder Letter. Details with respect to this exemption are set out in Part D.17 of this Section. With respect to any jurisdiction other than an Unrestricted Jurisdiction or a Restricted Jurisdiction, the general principles of the Schemes will apply (as described under "Other jurisdictions" above) notwithstanding the confirmations given in any relevant Claim Form or Account Holder Letter. TREATMENT OF PLC SHAREHOLDERS IN RESTRICTED JURISDICTIONS Corp has determined that distribution of securities to plc Shareholders pursuant to the Corp Scheme is currently prohibited by applicable securities laws or regulations requiring compliance with conditions or requirements that are unduly onerous (i) in Malaysia (with respect to New Shares and Warrants) and (ii) unless the exemption applicable with respect to distributions of securities to limited numbers of persons is available, in Italy (with respect to Warrants). plc Shareholders with registered addresses in Malaysia will be prohibited from receiving distributions of New Shares and Warrants pursuant to the Corp Scheme, and will receive cash instead as described above. plc Shareholders with registered addresses in Italy will be prohibited from receiving distributions of Warrants pursuant to the Corp Scheme, and will receive cash instead as described above, unless Corp determines that the above-mentioned exemption is available. Details with respect to this exemption are set out in Part D.17 of this Section. C.10 INSOLVENCY ANALYSIS Corp and plc believe that there are only two possible outcomes of the Group's current financial difficulties, which are the reorganisation of their liabilities through the proposed Schemes or the placing of the companies into administration or liquidation. Whilst Corp and plc believe that the Schemes are more beneficial to Scheme 99

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART C -------------------------------------------------------------------------------- Creditors than insolvency proceedings, Corp and plc believe that in the event of insolvency a more advantageous realisation of Corp's and plc's assets would be effected on an administration rather than a liquidation. Appendix 6 sets out a comparison between the position under the proposed Schemes and the hypothetical position that would be likely to face Scheme Creditors if plc and Corp were to go into administration as at 30 April 2003. The purpose of the insolvency analysis at Appendix 6 is to assist Scheme Creditors in determining whether to accept the proposals set out in this document. Scheme Creditors should read carefully the caveats, limitations and uncertainties set out in the analysis. Corp and plc believe that the Schemes give greater certainty overall and that the certainty of the day one distribution of cash, New Notes and New Shares is a major benefit to Scheme Creditors. This certainty would not be available under insolvency proceedings or on the enforcement of security. 100

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- D. GENERAL MATTERS RELATING TO THE RESTRUCTURING D.1 LOCKBOX ACCOUNT AND INTERIM SECURITY ARRANGEMENTS BACKGROUND As part of the arrangements to effect the Restructuring, Corp agreed to provide interim security (over the cash held by Highrose Limited (a special purpose subsidiary of Corp) in the Lockbox Accounts) to the Group's Syndicate Banks (in their capacities as Syndicate Banks, bilateral lenders to Corp and beneficiaries of guarantees from Corp (in such capacities "BANK CREDITORS")), the holders of the Bonds from time to time (apart from plc's wholly owned subsidiary Ancrane) and the Trustees (together the "SECURED BONDHOLDERS") and Barclays, as the only ESOP Derivative Bank which committed to support the Restructuring prior to 15 October 2002. These interim security arrangements took effect on 13 September 2002, on which date the balance in the Lockbox Accounts was approximately L866 million. The interim security arrangements were amended on 13 December 2002 and were further amended on 28 March 2003. The interim security has been provided to the Bank Creditors and Secured Bondholders on a pari passu basis, subject to the arrangements in favour of the participating ESOP Derivative Banks (see further details in Part D.2 of this Section). As at 27 March 2003, the balance held in the Lockbox Accounts was approximately L770.7 million. The 13 December 2002 amendments to the interim security, among other things: - removed a provision requiring the interim security to be released if a specified percentage of Bank Creditors and Secured Bondholders had not entered into written agreements to vote in favour of the Schemes on or before 15 business days after the date on which the originating application for the Corp Scheme was filed with the Court; and - released the undertakings which had been given on 13 September 2002 by members of the Informal Committee of Bondholders to enter into such written agreements. These amendments were agreed in consideration of an extension of time (until 15 March 2003) to complete the Restructuring and the waiver by the Bank Creditors and Informal Committee of Bondholders of any enforcement event which may have then existed in relation to the interim security as a result of the probable inability to complete the Restructuring by 31 January 2003. At the same time and as part of the amendment of the interim security, each of the then members of the Informal Committee of Bondholders and certain members of the current Co-ordination Committee provided letters of current intention to support the Restructuring and to vote in favour of the Schemes (which are detailed in Appendix 19 and are among the documents available for inspection). Corp and plc have not been notified of any changes in those intentions since that date. Further amendments were made to the interim security on 28 March 2003. These amendments, among other things, removed the provision requiring the interim security to be released at any time should any Bank Creditor (or any of its affiliates) precipitate an insolvency event with respect to any material Group Company. These amendments were agreed in consideration of an extension of time (until 30 June 2003) to complete the Restructuring and the waiver by the majority Bank Creditors and the majority members of the Informal Committee of Bondholders of certain enforcement events that may then have existed in relation to the interim security as a result, among other things, of the inability to complete the Restructuring by 15 March 2003. In addition to the extension of time to complete the Restructuring and waiver of enforcement events discussed above, on 26 March 2003 and 24 March 2003 respectively the requisite majorities of the Syndicate Banks and the members of the Informal Committee of Bondholders: (a) consented, for the purpose of the undertakings given in favour of the Syndicate Banks and the Informal Committee of Bondholders, to the entry by Corp, plc and other Group Companies into certain transactions (including those contemplated under the Scheme Implementation Deed) necessary to facilitate the Restructuring; and (b) agreed a number of additional carve-outs to those undertakings to permit Corp, plc and other Group Companies to enter into transactions contemplated in this document (provided that, subject to some exceptions, such transactions do not take effect until on or after the Effective Date of the Corp Scheme). 101

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- ENFORCEMENT EVENTS The interim security will become enforceable on the occurrence of an enforcement event. These events include: - material breach or termination of the undertakings described in Part B of this Section; - the commencement of formal insolvency proceedings in relation to a material Group Company (as listed in the interim security); - failure to achieve the Restructuring on the basis stated in the Heads of Terms (as varied in the manner announced on 18 March 2003) within the proposed timetable (or the likelihood of the same becoming evident); - failure to meet the sensitised Business Plan, if such failure would have a material and adverse effect on the interests of the beneficiaries of the interim security (or the likelihood of the same becoming evident); - that the post-Restructuring balance sheet is likely to be materially worse than contemplated by the sensitised Business Plan; or - that the Group is unlikely to have sufficient working capital post-Restructuring, if such event would have a material and adverse effect on the interests of the beneficiaries of the interim security. The occurrence of an enforcement event may materially prejudice the ability of Corp and plc to complete the Restructuring successfully. If the interim security were to be enforced, neither Corp nor plc would have any reasonable prospect of avoiding an insolvency proceeding. RELEASE OF INTERIM SECURITY The interim security is due to be released on 24 April 2003 ("RELEASE DATE"), being the date (as notified by HSBC, as trustee in respect of the interim security) falling one business day prior to the date on which the Corp Scheme Meeting will be held, unless on or within five business days prior to the Release Date, the Co-ordination Committee certifies that Bank Creditors and Secured Bondholders representing a majority in principal amount of the debt outstanding under the Bank Facility, bilateral facilities provided by Bank Creditors to Corp, bilateral guarantees given by Corp in favour of Bank Creditors and the Bonds do not believe that the requisite majority (being a majority in number representing 75 per cent. in value of Corp Scheme Creditors present and voting either in person or by proxy at the Creditors' Meeting in respect of the Corp Scheme) will approve the Restructuring. In light of discussions with the Syndicate Banks and the Informal Committee of Bondholders during the course of the Restructuring, Corp and plc currently believe that the interim security will be released on the Release Date. If the interim security has not been released prior to the Corp Scheme Meeting neither Corp nor plc will proceed with their respective Schemes and the interim security will remain in place in any subsequent insolvency proceedings, meaning that the Bank Creditors, Secured Bondholders and Barclays Bank PLC (as the only ESOP Derivative Bank which committed to support the Restructuring prior to 15 October 2002), would rank ahead of all unsecured creditors of Corp with respect to the cash held in the Lockbox Accounts. If the interim security is released and the Corp Scheme Meeting proceeds, the choice facing all Corp Scheme Creditors will be the same: either the Corp Scheme will be approved and implemented or the Corp Scheme will be rejected and in the inevitable insolvency proceeding which would follow such rejection the interim security would no longer be in place. The Syndicate Banks and the Informal Committee of Bondholders have indicated that they will not be prepared to release the interim security prior to the Corp Scheme Meeting unless, immediately before such release, Corp has confirmed to the Prospective Supervisors that Corp remains satisfied that the reserves built into the Corp Scheme are sufficient to meet distributions to all Corp Scheme Creditors and that Corp remains of the opinion that its statement as to the Corp Group's working capital contained in Part D.21 of this Section remains valid, and the Prospective Supervisors have confirmed to Corp that they have no reason to disagree with Corp's view that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors. 102

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- WITHDRAWALS Prior to release of the interim security (and in the absence of any enforcement event), and after the release of the interim security (in accordance with the lockbox arrangements set out in the undertakings in favour of the Syndicate Banks and members of the Informal Committee of Bondholders (as modified and renewed)), withdrawals from the Lockbox Accounts are to be approved, in order for the Group to meet its cash flow requirements, in accordance with an agreed cash flow forecast for the period from and including March 2003 to 30 June 2003. D.2 ARRANGEMENTS WITH ESOP DERIVATIVE BANKS BACKGROUND As part of the demerger of the Group's defence business at the end of 1999 involving the listing of plc as the new parent company of the Group, it was necessary to reorganise the incentive schemes to reflect the new Group structure, and a number of employee share option plans (the "ESOPs") were put in place (and detailed in the listing particulars of plc). The ESOPs entitle participating employees of certain Group Companies ("Opcos") in certain circumstances to call for shares in plc at specified exercise prices. Marconi Employee Trust was established by a trust deed in 1999 as a vehicle for acquiring and holding plc shares to be delivered when options were exercised under the ESOPs. MET was managed by an independent trustee, Bedell Cristin Trustees Limited. plc wrote to various Opcos whose employees were to participate in the ESOPs requesting that each confirm that it would bear the costs associated with the participation by its employees in the ESOPs (such letters, "Funding Letters"). In order to hedge some of the potential cost of acquiring shares to satisfy the Group's obligation under the ESOPs, BCTL entered into three ISDA master swap agreements ("ESOP Agreements") with the ESOP Derivative Banks (Salomon Brothers International Limited, Barclays Bank PLC and UBS AG) as counterparties. Under the ESOP Agreements, BCTL entered into certain equity swaps (as detailed in Appendix 11) which provided that in certain circumstances BCTL would be obliged to purchase plc shares in the future at prices which were fixed at the date of the contracts, and were in the region of 900 pence per share ("ESOP Derivative Transactions"). The obligations of BCTL under the ESOP Derivative Transactions were guaranteed by plc and were limited in recourse to the assets of MET held on trust by BCTL. As the market price of the Group's shares fell, certain of the ESOP Derivative Banks exercised their rights to call for cash collateral under the ESOP Derivative Transactions. BCTL needed to be put in funds in order to satisfy its obligation to provide such cash collateral. At the request of plc, Corp made available a credit facility (the "ESOP Collateral Loan") to BCTL for the purpose of providing cash collateral to the relevant ESOP Derivative Banks. The UBS ESOP Derivative Transaction has been terminated consensually. SBIL has purported to terminate its ESOP Derivative Transaction. The Barclays ESOP Derivative Transaction has not been terminated. plc's total current exposure under the ESOP Derivative Transactions is approximately L389 million. However, approximately L214 million, being the maximum amount of collateral payable under the ESOP Derivative Transactions, has been paid. A remaining amount of approximately L175 million remains due. During the course of the Restructuring negotiations the ESOP Derivative Banks asserted that they may have claims against the Opcos (in addition to plc) in respect of the ESOP Derivative Transactions, such claims arising from the Funding Letter arrangements. MOBILE ESCROW On 2 August 2002, Marconi Bruton Street Limited, a subsidiary of Corp, disposed of its entire shareholding in Marconi Mobile Holdings S.p.A. to Finmeccanica S.p.A. for approximately E571 million. The employees of Mobile and certain of its subsidiaries had participated in the ESOPs and certain members of the Mobile group ("Mobile Opcos") had countersigned Funding Letters. In order to ensure that the sale of Mobile was not delayed whilst the efficacy of the claims of the ESOP Derivative Banks was determined, approximately L25 million of the sale proceeds was placed in an escrow 103

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- account subject to the terms of an escrow agreement between, inter alia, the ESOP Derivative Banks, HSBC Bank plc, Corp and plc, pending resolution of the dispute or a court order. That sum reflected the L18 million maximum estimated potential liability of the Mobile Opcos (prior to the release of the relevant Funding Letters required in order to implement the sale of Mobile) arising from the participation of their employees in the ESOPs plus additional headroom. Given that the investigations into the merits of the arguments were at an early stage, the additional headroom was approximately L7 million. ESOP TERM SHEET The fact that the ESOP Derivative Banks asserted claims against Opcos made it necessary to devise a mechanism so that the ESOP dispute was ringfenced and could not jeopardise the Corp Group once the Restructuring contemplated by the Corp Scheme had become effective. On 28 August 2002, as part of the negotiations in connection with the Restructuring, a non-binding indicative ESOP Term Sheet providing for the creation of escrow accounts pending determination of the claims of the ESOP Derivative Banks was initialled by plc, Corp, representatives of the Co-ordination Committee, the Informal Committee of Bondholders and Barclays. The ESOP Term Sheet set out the manner in which the ESOP Derivative Banks, in exchange for agreeing prior to 15 October 2002 to support the Restructuring of Corp and plc, could take the benefit of the interim security and certain pre and post-Restructuring escrow arrangements. Up to L170 million (including the L25 million set aside under the Mobile Escrow Agreement) was to be set aside in escrow, on the Effective Date of the Corp Scheme, pending determination of the potential liabilities of Group companies to the participating ESOP Derivative Banks (those who had undertaken to support the Schemes) in relation to the ESOP Derivative Transactions. Only Barclays elected to participate in these arrangements and on 13 September 2002 Barclays, Corp and plc entered into a restructuring undertaking agreement under which Barclays undertook, subject to certain termination events, to vote in favour of the Schemes. The terms of the Barclays restructuring undertaking agreement are described in more detail in Appendix 19. ESOP ESCROW AGREEMENT A definitive agreement implementing the terms of the ESOP Term Sheet was entered into between plc, Corp, HSBC Bank plc and Barclays on 13 December 2002, the principal terms of which are summarised below: a. No Restructuring (i) If, prior to the Effective Date of the Corp Scheme, the Bank Creditors and Secured Bondholders appropriate the cash in the secured Lockbox Accounts as a result of the enforcement of the interim security, a proportionate part of the secured cash will be placed into an escrow account. This proportion will be calculated on the basis of ((83.49)/(100) X 145/850 X the credit balance of the secured cash at the time of enforcement). (ii) In the event of an enforcement, Barclays will first have to litigate with reasonable diligence against the Opcos to determine its rights (if any) under the Funding Letters. Barclays is then entitled to abandon or settle the litigation and, following agreement or a determination by the court or arbitral tribunal as to their rights against the secured escrow cash under the terms of the ESOP Escrow Agreement, recover such amounts from the secured escrow cash on that basis. b. Post-Restructuring If any Opcos are sold prior to the Restructuring becoming effective ("Subsequently Sold Opcos"), an amount to cover potential claims of Barclays against the Subsequently Sold Opcos will be paid into an account subject to separate arrangements similar to the Mobile Escrow Agreement. To date two such escrow agreements have been entered into in relation to Subsequently Sold Opcos, the amount of each being less than L1 million. The terms of the ESOP Escrow Agreement will continue to apply until Corp pays the Settlement Amount referred to below to the ESOP Derivative Banks and the escrow cash held under the terms of the Mobile Escrow Agreement and any Subsequently 104

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Sold Opco escrow agreements has been paid to Corp. Thus, the terms of the ESOP Escrow Agreement relating to the escrow to be established post-Restructuring are now in practical terms superfluous. The terms relating to the charged escrow cash may be relied upon if the Settlement Amount is not paid by Corp to the ESOP Derivative Banks. ESOP SETTLEMENT On 26 March 2003, Corp and plc reached definitive agreement with all the ESOP Derivative Banks to settle their ESOP derivative related claims against the Group (the "ESOP Settlement Agreement"). Under the terms of the settlement, which is conditional upon the Corp Scheme becoming effective, Corp will pay a total of L35 million to the ESOP Derivative Banks in full and final settlement of their respective ESOP related claims against the Group. The Settlement Amount will be paid from the fund of up to L170 million which was to have been set aside by Corp under the ESOP Escrow Agreement and the Mobile Escrow Agreement. The settlement has made available approximately L135 million in cash which forms part of the L340 million comprising the cash element of the Corp Scheme Consideration. Without the ESOP settlement, the L135 million sum would not have formed part of the Corp Scheme Consideration. The Boards of Corp and plc believe that the ESOP settlement was in the best interests of Corp and plc and their respective stakeholders as a whole. In reaching this conclusion, the Boards of Corp and plc took appropriate legal advice and considered a number of relevant factors, including the merits of the claims of the ESOP Derivative Banks, the desire to reduce the cost and expense of continuing litigation, the potential saving in the interest burden from which the Group will benefit by settling the ESOP derivative dispute, the benefits for the Schemes and certainty as to the amount of the Corp Scheme cash distribution that such a settlement brings. The principal terms of the ESOP Settlement Agreement are as follows: - Corp will pay the Settlement Amount to the ESOP Derivative Banks (in the agreed proportions) on the Effective Date of the Corp Scheme (provided such date is on or before 31 December 2003); - When each ESOP Derivative Bank has received its share of the Settlement Amount: -- plc will release and waive any and all claims against the Opco's under or in relation to the Funding Letters; -- each ESOP Derivative Bank will release and waive any and all claims against BCTL, plc and each Opco (and their respective directors and officers) under or in relation to the Funding Letters (including releases by plc thereof), the ESOP Derivative Transactions and the plc guarantee of the ESOP Derivative Transactions; -- BCTL will release and waive any and all claims against each ESOP Derivative Bank, plc and each Opco (and their respective directors and officers) under or in relation to the Funding Letters (including releases by plc thereof), the ESOP Derivative Transactions and the plc guarantee of the ESOP Derivative Transactions; and -- plc will release and waive any and all claims against any ESOP Derivative Bank (and their respective directors and officers) under or in relation to Funding Letters (including releases by plc thereof), the ESOP Derivative Transactions and the plc guarantee of the ESOP Derivative Transactions; - The ESOP Escrow Agreement, the Mobile Escrow Agreement and any Subsequently Sold Opcos escrow agreements shall terminate and the escrow cash held under the terms of the Mobile Escrow Agreement and Subsequently Sold Opco escrow agreements shall be paid to Corp; - The current litigation by SBIL against plc in connection with the SBIL ESOP Agreement will be discontinued with no order as to costs; - Until the Effective Date of the Corp Scheme, the ESOP Derivative Banks may not commence or further any claims or proceedings against BCTL, plc or any Opco (or their respective directors and officers) under the Funding Letters (including releases thereof), the ESOP Derivative Transactions or 105

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- the plc guarantee of the ESOP Derivative Transactions. This standstill terminates on the occurrence of certain events set out in the ESOP Settlement Agreement, including (a) the release of Funding Letters in certain circumstances; (b) the enforcement of the interim security; (c) the Corp Scheme not obtaining the requisite approval at the Corp Scheme Meeting; (d) the Court sanction for the Corp Scheme not being obtained; (e) a demand being made for the repayment of the Bank Facility; (f) an insolvency event occurring in relation to Corp or, subject to certain limitations, plc; or (g) the Effective Date for the Corp Scheme not having occurred on or before 31 December 2003; and - The ESOP Derivative Banks will not, subject to limited exceptions, transfer, sell or assign their rights arising from plc's guarantee of the ESOP Derivative Transactions. If the Corp Scheme does not become effective, Corp will not be required to pay the Settlement Amount and the ESOP Escrow Agreement, the Mobile Escrow Agreements and the Subsequently Sold Opco escrow agreements will continue to apply. All claims of the ESOP Derivative Banks under the plc guarantee of the ESOP Derivative Transactions are excluded from the plc Scheme and no distribution from the plc Scheme will be made in respect of them. On 26 March 2003, UBS and Citibank N.A. (as the Syndicate Bank affiliate of SBIL) entered into undertakings to exercise in certain circumstances all votes relating to certain debt claims against Corp and plc in favour of the Schemes (as detailed further in Appendix 19). The non-ESOP related debt is transferrable without restrictions. At the same time, the Barclays restructuring undertaking agreement (dated 13 September 2003) was amended to bring the transferability provisions into line with those applying to UBS and Citibank. D.3 ARRANGEMENTS TO PRESERVE RIGHTS AT PLC LEVEL Various concerns were raised by either or both of the Informal Committee of Bondholders and the Co-ordination Committee during the course of the Restructuring discussions concerning the maintenance of guarantee claims against plc and arrangements were put in place in order to deal with these concerns. Details of the concerns and the arrangements which were put in place are set below. In making its decision to approve these arrangements, plc took into consideration that it was correct in principle that the rights should be preserved, in order to put the creditors concerned in the same position as if both companies had been wound up. PRESERVING RIGHTS UNDER THE SCHEMES IN THE EVENT THAT BOTH SCHEMES ARE SUCCESSFUL plc has guaranteed the repayment of certain primary debt obligations of Corp. In order to preserve the recoveries of creditors of Corp, who may also have the benefit of a plc guarantee ("GUARANTEE CREDITORS"): a. the Corp Scheme provides that no Scheme Claim under the Corp Scheme would be reduced, or in any way affected, by the compromise of any claims of that Scheme Creditor against plc pursuant to the terms of the plc Scheme; and b. a corresponding provision appears in the plc Scheme. THESE PROVISIONS ARE OF GENERAL APPLICATION TO THE EXTENT THAT A CREDITOR OF ONE COMPANY HAS A GUARANTEE CLAIM IN RESPECT OF THAT CLAIM AGAINST THE OTHER COMPANY. PRESERVING RIGHTS IN THE EVENT THAT THE CORP SCHEME IS SUCCESSFUL BUT THE PLC SCHEME FAILS In addition, the Informal Committee of Bondholders and the Co-ordination Committee indicated that they were concerned to ensure that, even if the plc Scheme failed but the Corp Scheme was successful, guarantee creditors could maintain the ability to claim 100 per cent. of their claim in respect of the plc guarantee against plc. The concern arose because, if the plc Scheme were to fail, plc would be placed into liquidation. In the event that a distribution was made under the Corp Scheme before a proof of debt could be submitted in a subsequent liquidation of plc, the guarantee creditors would have to give credit to the liquidator of plc for their recoveries under the Corp Scheme. 106

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- The Informal Committee of Bondholders and the Co-ordination Committee indicated on a number of occasions that it was central to their support of the Restructuring that guarantee creditors be entitled to prove for the full amount of their debt in any subsequent liquidation of plc should the plc Scheme fail. In order to preserve the ability of guarantee creditors to claim the full amount of their claim against plc in these circumstances the Informal Committee of Bondholders and the Co-ordination Committee required plc to enter into a deed poll on terms proposed by the Informal Committee of Bondholders and the Co-ordination Committee. It is open to any creditor with a guarantee claim to have the benefit of the deed poll. The deed poll requires that in the event that any guarantee creditor is required to give credit to plc in a liquidation for any recoveries made under the Corp Scheme, plc will pay a further sum equal to the amount of the distribution that the relevant creditor received in the Corp scheme i.e. it is intended that a new debt obligation of plc will be created. The deed poll does not have the effect of permitting a creditor to receive more than a 100 per cent. recovery in respect of the underlying claim. PRESERVATION OF THE BOND GUARANTEE Clause 4.9 of the Trust Deed provides that the guarantee given by plc in respect of the Eurobonds will terminate when Corp delivers to the Eurobond Trustee a certificate to the effect that plc has been released from its guarantees in respect of certain bank debt. Section 12.03 of the Yankee Bond Indenture states that the plc guarantee will terminate on the date that plc is released from its guarantees in respect of certain bank debt and the Eurobonds. In order to preserve the guarantee claim of the Trustees, Corp and plc entered into a Bondholder Confirmation Letter which provided that notwithstanding the provisions of Clause 4.9 of the Trust Deed and Section 12.03 of the Yankee Bond Indenture or the receipt of a Distribution under the Corp Scheme or the cancellation of the Bonds, the guarantee of plc remains in full force and effect and is extended for the benefit of all Definitive Holders. D.4 WORKING CAPITAL RETAINED CASH The Group is expected to retain approximately L602 million of cash following the Restructuring, comprising approximately: a. L167 million of restricted cash; b. L112 million of trapped cash; c. L197 million retained for normal working capital needs; d. L96 million representing net cash outflow to cash break even; and e. L30 million representing cash in transit and therefore not available for distribution. "Restricted cash" is cash employed as collateral or available to be granted as collateral in connection with performance bonding arrangements. Any cash collateral releases from existing performance bonds, and any balance remaining in the Existing Performance Bond Escrow Account on the first anniversary of the Effective Date for the Corp Scheme, in an amount (when aggregated with cash collateral releases made to the security trustee under the Performance Bonding Facility between the Issue Date and the first anniversary of the Effective Date of the Corp Scheme, together with interest thereon) not exceeding the lesser of L25 million or 50 per cent. of the amount of the Performance Bonding Facility, if Corp should cancel a portion of that facility, will be transferred to the security trustee under the Performance Bonding Facility, to collateralise performance bonds and similar instruments issued under that facility. Any excess amount will be paid into the Mandatory Redemption Escrow Account to be applied in redemption of the New Junior Notes and, once all New Junior Notes have been repaid, the New Senior Notes. On the termination or cancellation of the Performance Bonding Facility, all released collateral (other than that required to support long-dated performance bonds) will be paid into the Mandatory Redemption Escrow Account to be applied in redemption of the New Junior Notes and, once all New 107

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Junior Notes have been repaid, the New Senior Notes (as described further below). See Appendix 8 for further information on the circumstances in which restricted cash will be released. "Trapped cash" includes (a) cash held in relation to existing insurance liabilities, (b) cash held as collateral under existing local bilateral debt facilities, (c) part of the proceeds from the disposal of Mobile in August 2002 to be held in escrow until August 2004 and (d) cash held in accounts in various jurisdictions to meet local working capital requirements (where such cash is not, for local regulatory or other reasons, easily accessible to meet wider Group working capital needs). The "net cash outflows to cash break even" figure represents cash to be retained by the Group (net of permitted remaining disposal proceeds) needed to fund the Group through to cash break even. WORKING CAPITAL FACILITIES Performance Bonding Facility In order to ensure that the Group has sufficient bonding facilities available to it following the Effective Date of the Corp Scheme HSBC Bank plc and JP Morgan Chase Bank have agreed to provide a L50 million committed revolving facility for the issuance of Performance Bonds at the request of Marconi Bonding Limited, for the purpose of supporting (directly or indirectly) obligations of members of the Group to third parties incurred in the ordinary course of the Group's trade or business. The Performance Bonding Facility is also available for the purpose of supporting any financing facilities which have been provided to members of the Group for the purpose of supporting directly obligations of members of the Group incurred in the ordinary course of the Group's trade or business (other than obligations in respect of financial indebtedness) (for example, in connection with supporting a bonding facility in a foreign currency where bonds denominated in such foreign currency are not available under the Performance Bonding Facility). The Performance Bonding Facility will permit the issue, on behalf of Corp, of a letter of credit (with a face value of up to L2 million) in favor of the plc Scheme Supervisors from time to time to support plc's Ongoing Costs (within the L50 million commitment). The Performance Bonding Facility may be utilised at any time during the period from the Effective Date of the Corp Scheme to the date falling 18 months thereafter. Marconi Bonding Limited has the right to request an extension to such availability period (to a date falling no later than 30 months after the Effective Date of the Corp Scheme (but without the participating banks having any obligation to agree such extension)). Performance Bonds may be issued in sterling, US dollars, Euro or (with the approval of the relevant issuing bank) any other readily available currency freely convertible into sterling. The form of the Performance Bond and identity of the beneficiary must be approved by the relevant issuing bank (having regard to that issuing bank's formal internal policies at the relevant time, and to all relevant legal and regulatory restrictions). In the case of Performance Bonds with an expiry date falling after 31 December 2010, the approval of the relevant issuing bank and the approval of the relevant banks providing the Performance Bonding Facility is required. In addition to an issuance fee of L1,000 for each Performance Bond, a bonding fee equal to 0.50 per cent. per annum of the outstanding amount of each Performance Bond is payable quarterly in advance, for the account of the participating banks. A fronting fee equal to 0.10 per cent. per annum of the outstanding amount of each issued Performance Bond (less the issuing bank's own proportion) is payable quarterly in advance, for the account of the relevant issuing bank. An arrangement fee of L1,000,000 was payable on the date of the Performance Bonding Facility to the facility agent for distribution to the banks participating in the Performance Bonding Facility. The obligations of each obligor under the Performance Bonding Facility are irrevocably and unconditionally guaranteed by Corp. The Performance Bonding Facility is secured by, inter alia, a charge over cash contained in certain blocked deposit accounts (the "Secured Accounts") between Marconi Bonding Limited and HSBC Bank plc as security trustee. Marconi Bonding Limited will be required, on the date of issuance of a Performance Bond, to deposit (in the currency of the relevant Performance Bond or, where such Performance Bond is issued in a currency other than sterling or Euros, US dollars) an amount equal to 50 per cent. of the maximum face value of such Performance Bond into such Secured Accounts. As further security for the obligations of Marconi Bonding Limited under the Performance Bonding Facility, Marconi Bonding Limited will ensure that additional amounts are deposited into the Secured Accounts in accordance with the terms of the New Notes. The Performance 108

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Bonding Facility contains certain events of default after the occurrence of which the agent is permitted to cancel the total commitments under the Performance Bonding Facility and/or to declare that full cash collateral in respect of each Performance Bond is immediately due and payable (including events of default relating to non-payment, failure to comply with security undertakings, failure to comply with other obligations, misrepresentation, cross default, insolvency, unlawfulness and repudiation of the Performance Bonding Facility documents). In accordance with the Security Trust and Intercreditor Deed, the banks providing the Performance Bonding Facility will rank ahead of the Noteholders in any enforcement of the Security. The Security Trust and Intercreditor Deed also provides that the security trustee under the Performance Bond Facility and the banks may not take action to enforce the obligations of the obligors under the Performance Bonding Facility following a payment event of default thereunder until the earlier of (i) 180 days after notice to the Security Trustee under the Security Trust and Intercreditor Deed of the occurrence of such payment event of default or (ii) the acceleration of the New Senior Notes (see Appendix 10 for further details). US Working Capital Facility In order to ensure that Marconi Communications, Inc. has sufficient working capital post-Restructuring, MCI has entered into a working capital facility agreement with Liberty Funding, L.L.C., pursuant to which Liberty will provide a US$22,500,000 revolving credit facility to MCI. The Working Capital Facility is secured by a first mortgage lien on a parcel of MCI's real property (including buildings, improvements, building materials and fixtures) located in Warrendale, Pennsylvania, USA ("Property"). The Working Capital Facility is subject to a fixed interest rate of 15 per cent. per annum (payable monthly) and will mature on 26 November 2004. It will be used by MCI for working capital and general corporate purposes. Liberty's fees and costs include an arrangement fee of 6 per cent. of the facility amount, an unused commitment fee of 1 per cent. per annum on any undrawn portion, and a 5 per cent. late charge for payments overdue by more than ten days. In addition to the mortgage over the Property, all of MCI's right, title and interest in and to all leases of all or any part of the Property (including any rents) will be assigned to Liberty, and MCI will provide assurances and indemnities to Liberty relating to environmental matters affecting the Property, and financing statements for perfecting security interest in the fixtures. A second mortgage lien on the Property (and assignments of related leases and rents) will be granted in favour of, inter alia, the providers of the Performance Bonding Facility and the Noteholders and, consequently, an intercreditor agreement will be entered into between Liberty and the Security Trustee. See Appendix 10 for further details of this intercreditor agreement. Covenants contained in the Working Capital Facility Agreement include indemnification from MCI in favour of Liberty in relation to liabilities and claims relating to the Property, MCI's pledge to keep the buildings, structures, improvements and fixtures insured and MCI's covenant not to dissolve, merge or consolidate with any other person (other than an affiliate of MCI) or dispose of all or a substantial portion of its assets relating to its BBRS Business. Although the obligations of MCI in respect of this facility are limited recourse, there are exceptions for, inter alia, failure to maintain insurance coverage, fees and costs incurred in enforcing/collecting sums due and MCI's environmental indemnity obligations, for which MCI has full liability. The Working Capital Facility Agreement contains certain events of default the occurrence of which would permit Liberty to cease making further advances, terminate its commitment and/or accelerate repayment of the Working Capital Facility. Intra-Group funding There are currently a significant number of intra-Group lending arrangements in place between members of the Wider Corp Group. These comprise loans from Corp to its Affiliates, loans from Corp's Affiliates to Corp and loans between Corp's Affiliates. Any intra-Group loan claims of Corp's Affiliates against Corp will be Excluded Claims for the purposes of the Corp Scheme and will therefore remain in place following the implementation of the Corp Scheme (See Part C.7 of this Section and Appendix 9 for further details on Excluded Claims). Following the Effective Date of the Corp Scheme, the Wider Corp Group will be subject to the intra-Group lending restrictions contained in the indentures governing the New Notes. The scope of those restrictions will depend on whether the relevant debtor or creditor is a Guarantor or a non-Guarantor. The restrictions are 109

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- described more fully in Appendix 8. The Security Trust and Intercreditor Deed also contains provisions regulating certain intra-Group loans and actions in respect thereof, which are described more fully in Appendix 10. COLLATERAL FOR EXISTING PERFORMANCE BONDS General On the Effective Date of the Corp Scheme, Corp will deposit approximately L43.5 million of the L167 million of restricted cash attributable to performance bonding collateral into the Existing Performance Bond Escrow Account. Withdrawals from that account will be made to satisfy valid and enforceable cash collateral demands made by banks, insurance companies or other financial institutions who have issued performance bonds ("Existing Performance Bonds") on behalf of members of the Group prior to the Effective Date, upon certification by Corp to the Escrow Trustee. Cash collateral releases from Existing Performance Bonds, and any balance remaining in the Existing Performance Bond Escrow Account on the first anniversary of the Effective Date for the Corp Scheme in an amount (when aggregated with cash collateral releases made to the security trustee under the Performance Bonding Facility between the Issue Date and the first anniversary of the Effective Date for the Corp Scheme, together with interest thereon) not exceeding the lesser of L25 million or 50 per cent. of the amount of the Performance Bonding Facility, if Corp should cancel a portion of that facility, will be transferred to the security trustee under the Performance Bonding Facility. Any excess amount will be deposited into the Mandatory Redemption Escrow Account to be applied to redeem the New Junior Notes and, once all New Junior Notes have been repaid, the New Senior Notes. On the termination or cancellation of the Performance Bonding Facility, all released collateral (other than that required to support long-dated performance bonds) will be paid into the Mandatory Redemption Escrow Account to be applied to redeem the New Junior Notes and, once all New Junior Notes have been repaid, the New Senior Notes (as described further below). Determination of bonding collateral requirements As part of its determination of the post-Restructuring working capital requirements of the Group, Corp sought to ascertain an appropriate level of provision to be made for potential cash collateral calls in respect of Existing Performance Bonds (other than those Existing Performance Bonds which are already fully collateralised). That determination was made on the basis of Corp's assessment of the risk of individual issuers of Existing Performance Bonds calling for cash collateral against their outstanding exposure, based on an analysis of the rights which such issuers may have to make cash collateral calls. Specific provision has been made by Corp for all Existing Performance Bonds where the issuers of such bonds have unconditional rights to call for cash collateral at any time or have conditional rights to call for cash collateral where those conditions will be triggered by the Restructuring. With respect to issuers of Existing Performance Bonds that have conditional rights to call for cash collateral (where such conditions will not be triggered by the Restructuring per se), Corp has allocated a higher provision to those where it considers the conditions have been, or are more likely to be, triggered and a lower (or zero) provision where it considers that the conditions are unlikely to be triggered. Corp has made no provision in respect of issuers which it considers have no rights to call for cash collateral. Under the Heads of Terms, it was agreed that Corp would place up to L55 million in the Existing Performance Bond Escrow Account to be used for cash collateral calls in respect of Existing Performance Bonds. Corp had previously assessed that a provision of a higher amount would be an adequate provision in respect of potential cash collateral calls for Existing Performance Bonds. In order to be satisfied that the L55 million deposit which was permitted to be made into the Existing Performance Bond Escrow Account by Corp on the Effective Date would be an adequate reserve in respect of Existing Performance Bonds, Corp entered into arrangements with certain (current and former) Syndicate Bank issuers of Existing Performance Bonds during February and March 2003. Corp agreed to provide each participating Syndicate Bank with collateral (in the form of a cash-backed letter of credit) for 50 per cent. of the principal amount of the outstanding uncollateralised Existing Performance Bonds issued by it. In return for that provision of collateral, each of those Syndicate Banks agreed to waive all of its rights to demand cash collateral in respect of Existing Performance Bonds issued by it (except in the case of insolvency of Corp or the relevant Subsidiary, a demand by the beneficiary under the relevant Existing 110

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Performance Bonds, or acceleration under the New Notes). Because this arrangement was agreed with the Syndicate Banks on a collective basis (which Corp considered to be necessary to preserve stability amongst the Syndicate Banks), collateral (of approximately L1.13 million in aggregate) was provided to two Syndicate Banks (whose Existing Performance Bonds exposure totals approximately L2.27 million) in respect of which Corp would not otherwise have made cash collateral provision (on the basis that Corp considers that those issuers have no rights, ambiguous rights or conditional rights to call for cash collateral which are unlikely to be triggered). However, as at 27 March 2003, on a collective basis, arrangements had been entered into to provide approximately L11.50 million of collateral in return for a waiver of rights to call for cash collateral of approximately L19.03 million in respect of Existing Performance Bonds with a face value of approximately L21.30 million. In the absence of this arrangement Corp may have been required to make a cash collateral provision of approximately L19.03 million in respect of such bonds. One of the participating Syndicate Banks (in respect of which Corp would otherwise have been required to make 100 per cent. cash collateral provision) was provided with collateral for approximately 61 per cent. of the principal amount of the outstanding uncollateralised Existing Performance Bonds issued by it. This resulted from certain bonds issued by that Syndicate Bank expiring between the time that Corp agreed the 50 per cent. collateral figure with that bank and the time at which the arrangements with the Syndicate Bank issuers were implemented. Similar arrangements may be entered into (in the period up to the date of the Scheme Meeting in respect of the Corp Scheme) with other (current and former) Syndicate Bank issuers of Existing Performance Bonds. Such arrangements, if entered into, are expected to result in the provision of collateral with a value of less than L3 million. Prior to the Scheme Meeting in respect of the Corp Scheme, alternative arrangements may be entered into with one other Syndicate Bank issuer of uncollateralised Existing Performance Bonds which did not take part in the above arrangements. Under such alternative arrangements, this bank would agree to release collateral (in the form of a cash backed letter of credit) totalling approximately E10.23 million which it already holds against certain liabilities of a former Subsidiary of Corp (and which it is entitled to retain against such liabilities) in consideration for the issue of a new cash-backed letter of credit (with a face value of approximately E9.85 million) to collateralise Existing Performance Bonds issued by it (totalling approximately E9.85 million). D.5 SCHEME IMPLEMENTATION DEED The Scheme Implementation Deed (the "DEED") was entered into between Corp, plc, E-A Continental Limited, Ancrane, Marconi Nominees Limited, British Sealed Beams Limited and various other Group companies on 27 March 2003. The primary purpose of the Deed was to ensure that legally binding arrangements were in place to govern the rights and obligations between, inter alia, Corp and plc in implementing the Restructuring. Pursuant to the Deed, Corp, plc, E-A Continental Limited, Ancrane, Marconi Nominees Limited, British Sealed Beams Limited and various other Group companies have agreed to perform certain obligations and undertaken not to do certain acts including, but not limited to, approving all shareholder resolutions necessary or desirable to give effect to the Corp Scheme, assigning or novating certain guarantee obligations and/or licence agreements, providing all reasonable assistance and information and undertaking all reasonable acts and deeds to give effect to the assignment of certain Intellectual Property, making certain intra-group tax loss and group relief surrenders and providing certain tax indemnities. Ancrane has agreed to make a repayment of capital in specie to plc of all of its assets, other than L100. Corp has also agreed to procure the issue of a letter of credit (under the Performance Bonding Facility) in an amount of L2 million in favour of the plc Scheme Supervisors from time to time for them to draw on in relation to plc's Ongoing Costs. In the event that Corp is unable to procure the issue of such letter of credit, it has undertaken to provide the sum of L2 million for the plc Scheme Supervisors to draw on in relation to plc's Ongoing Costs on similar terms to those set out in the Scheme Implementation Deed and the Performance Bonding Facility Agreement in relation to the letter of credit. Certain obligations and undertakings of the parties to the Deed (including Corp's obligation to procure a letter of credit for plc's Ongoing Costs) are conditional upon and subject to the Corp Scheme becoming effective and will, in part, give effect to the implementation of the Corp Scheme upon it becoming effective. Brief particulars of the Scheme Implementation Deed are contained in Appendix 18. 111

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- D.6 STATEMENT AND WAIVER OF INTER-COMPANY BALANCES In order to facilitate the effective implementation of the Schemes, and in particular to effect a clean up of existing inter-company claims owed to or by Corp and plc, Corp and plc have entered into a statement and waiver of intercompany balances agreement (the "Statement and Waiver Agreement") with certain other Group companies. The effect of the Statement and Waiver Agreement is to preserve all known and stated claims existing between (A) Corp or plc and (B) the participating Group companies, and to waive all other claims which arise by reference to circumstances existing prior to the Effective Date of the Corp Scheme. In this sense there will be more certainty as to the level of any claims owed to or by Corp and plc after the Effective Date of the Corp Scheme. In so far as it involves plc, the Statement and Waiver Agreement has limited effect in that all known claims against plc will be schemed under the plc Scheme (and will receive a distribution from the plc Scheme) and all known claims of plc against Corp and its subsidiaries have been transferred to Corp prior to the Record Date (in consideration for a reduction in the amount of the Corp's existing claim against plc). Under the Statement and Waiver Agreement the following intra-group claims will be preserved as between (a) Corp and plc and (b) the participating Group companies: - disclosed intra-group loan balances in existence as at 31 December 2002 (plus interest accrued at such applicable commercial rate of interest as agreed between the parties to the respective loan); - any intra-group loan made on or after 1 January 2003 in the ordinary and usual course of business or with certain previously agreed creditor consent, including interest accrued at such applicable commercial rate of interest as agreed between the parties to the respective loan; - any trading and current account liabilities in existence as at 31 March 2002 (in the case of any participating Group company which is a trading or an active non-trading company) or 30 September 2002 (in the case of any dormant participating Group company). Such liabilities are determined by reference to the management accounts upon which the audited consolidated financial accounts of plc, as at 31 March 2002 or 30 September 2002 (as applicable) were prepared; - any trading and current account liabilities incurred in the ordinary and usual course of business after 31 March 2002 between (a) Corp and/or plc, and (b) any participating Group company which is a trading or an active non-trading company; - any counter indemnity or equivalent reimbursement obligation (which is written or is implied by law and whether or not contingent) arising under any financial guarantee or indemnity (which is written or is implied by law) and is: (a) in favour of any third party which is not a member of the Group (including the issuer of any performance bond, bank guarantee or similar instrument), and (b) in respect of any contractual obligations of the provider of the counter indemnity or equivalent; provided that where any payment has been made under such a guarantee or indemnity on or before 31 March 2002, the resultant counter indemnity shall not be preserved; - any counter indemnity or equivalent reimbursement obligation (which is written or is implied by law and whether or not contingent) arising under any written non-financial guarantee or indemnity (which is written or implied by law) and is: (a) in favour of any person which is not a member of the Group, and (b) in respect of any contractual or implied by law obligations of the provider of the counter indemnity or equivalent and (c) disclosed in a schedule to the Statement and Waiver Agreement; provided that where any payment has been made under such a guarantee or indemnity on or before 31 March 2002, the resultant counter indemnity shall not be preserved; and - any other specified claims. All other claims of Corp or plc against each participating Group company and all other claims of each participating Group company against Corp or plc, will be released with effect from the Effective Date of the Corp Scheme. The Statement and Waiver Agreement does not affect claims which arise out of or in relation to any matter or circumstance arising after the Effective Date of the Corp Scheme. 112

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- A list of Group companies that have already agreed to participate in the Statement and Waiver Agreement is contained at paragraph 2.2 of Appendix 19. Other Group companies may be added prior to the Effective Date of the Corp Scheme. D.7 RECAPITALISATION OF GUARANTORS In order to facilitate the giving of the Guarantees as part of the new security package to support the New Notes (see Appendix 10 for further details), certain of the Guarantors will need to be recapitalised. Most of these recapitalisations are intended to be effected one or two Business Days prior to the Effective Date of the Corp Scheme, although some may need to be effected before then. In conjunction with the recapitalisations, it is also intended to unwind or formalise certain intra-group financing arrangements. The recapitalisations and ancillary transactions will involve the direct and indirect parent companies of the relevant Guarantors, as well as certain other Group companies or entities that owe or are owed intra-group balances by the relevant Guarantors. Each recapitalisation is intended to be effected by a number of sequential intra-group transactions which may include: the restatement of terms of intra-group debt; injections of equity by parent companies into subsidiaries; repayments, assignments, novation or release of existing intra-group claims; and the issue of equity by subsidiary companies in return for (a) assignments of intra-group claims or (b) reductions in intra-group balances owed to their parent companies. For those transactions which require actual cashflow, the relevant series of intra-group transactions will involve the "round-tripping" of cash, commencing and ending in each case with Corp (as the ultimate holding company of the Guarantors). D.8 WAIVER OF PLC SHAREHOLDER VOTE As referred to in Part C.5 of this Section, the UKLA has granted a waiver of the provision in the Listing Rules which would otherwise require the consent of the shareholders of plc to the issue of the New Shares pursuant to the Corp Scheme. Accordingly, the effectiveness of the Schemes is not conditional on the approval of the shareholders of plc. D.9 CAPITAL REDUCTION As part of the Restructuring, Corp will apply to the Court for the purpose of implementing the Capital Reduction pursuant to section 135 of the Act. The Capital Reduction will involve the cancellation of the Non-Voting Deferred Shares arising on the conversion of the existing issued ordinary shares in the capital of Corp held by plc and Marconi Nominees Limited and the cancellation of Corp's share premium account (including that arising on the issue of New Shares), to create a reserve which it is expected will eliminate the deficit on the profit and loss account that would otherwise be shown on Corp's balance sheet as at 31 March 2003. As can be seen from note g. iii) to the Corp unaudited pro forma consolidated balance sheet in Appendix 2, the unaudited deficit on Corp's profit and loss account in its own unaudited balance sheet as at 30 September 2002 was approximately L2,767 million. The cancellation of the Non-Voting Deferred Shares and Corp's existing share premium account would reduce this by approximately L843 million, but approximately L3,306 million of share premium account is expected to arise on the issue of the New Shares so the reserve arising on the Capital Reduction is expected to exceed the 30 September 2002 deficit on Corp's profit and loss account by L1,382 million. The excess of the reserve over the 31 March 2003 deficit on Corp's profit and loss account will initially constitute Corp's special reserve referred to below. Prior to confirming the Capital Reduction, the Court will require Corp to give an undertaking designed to protect persons who are creditors of Corp on the date the Capital Reduction becomes effective. This undertaking will require the maintenance by Corp and its subsidiaries of special reserves, which will not be distributable to shareholders of Corp until the creditors of Corp to be protected have been paid off or the Court has agreed otherwise. It is anticipated that the Capital Reduction will become effective shortly after the Effective Date of the Corp Scheme. Although Corp cannot guarantee that the Capital Reduction will become effective, it will not affect the effectiveness of the Schemes in any event. 113

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- D.10 SHARE INCENTIVE PLANS INTRODUCTION The Group currently operates the share incentive plans set out in the table below. The Plans were designed to incentivise participating Group employees, directors and consultants as part of their remuneration arrangements. Under these Plans, Participants were given rights to acquire plc Shares either at a specified price or, where certain objectives were achieved, at no cost (the latter are known as nil-cost options). Certain options, including some of the nil-cost options are already exercisable. These optionholders can acquire plc Shares prior to the plc Shareholders Record Time. As a result of the Restructuring, more of the options will become exercisable. However, this will be after the plc Shareholders Record Time when plc Shares will have no value. Due to plc's current share price the majority of options granted to Participants under the Plans are now underwater (that is, shares in plc are worth less than the Participants would have to pay to acquire them). It is assumed that holders of those options which are currently exercisable will not exercise them. Of those options where the plc Shares subject to them are worth more than the price that Participants must pay for them, it is only those optionholders who can and do exercise their options prior to the plc Shareholder Record Time who will receive New Shares and Warrants. After implementation of the Restructuring, all remaining options will be valueless. As at 28 February 2003, options over approximately 149.6 million plc Shares are outstanding. This represents approximately 5.4 per cent. of plc's current total issued share capital. plc has also granted 47.3 million phantom options in respect of which, on exercise, Participants ordinarily receive cash rather than shares (if a gain has been made). <Table> <Caption> Number of shares over which options Range of Name of plan are outstanding option prices ------------ ------------------ ------------- <S> <C> <C> The GEC 1984 Managers' Share Option Scheme 671,044 183-266p ------------------ ------------- The GEC Employee 1992 Savings-related Share Option Scheme 1,985,076 203-273p ------------------ ------------- The GEC 1997 Executive Share Option Scheme 7,959,308 311-385p ------------------ ------------- The Marconi UK Sharesave Plan 2,297,688 538-748p ------------------ ------------- The Marconi International Sharesave Plan 1,342,615 737p The Marconi Launch Share Plan 19,620,228 Nil-cost The Marconi 1999 Stock Option Plan 98,449,888 35-1030p The Metapath Software Corporation 1995 Stock Option Plan 144,164 3-274p The Metapath Software International Inc. 1999 Stock Option Plan 2,386,061 212-957p The Mariposa Technology Inc. 1998 Employee Incentive Plan 320,684 9-56p The Marconi Restricted Share Plan 1,795,184 Nil-cost-947p The Marconi Welcome Plan 2,642,687 Nil-cost The Marconi Long Term Incentive Plan 629,559 Nil-cost The Northwood Technologies Inc.

On this basis it might appear that nil cost options are in the money. However, except for those which are currently exercisable, this is not the case. Some optionholders holding nil cost options which are not currently exercisable will become entitled to exercise their options when the Restructuring takes effect, because Corp will cease to be a subsidiary of plc, and other such optionholders will become so entitled if plc goes into liquidation. However, neither event will take place until after the Corp Scheme has become effective, by which time plc Shares will have no value. 114

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Optionholders currently entitled to exercise their nil cost options who do so in time to receive plc Shares before the plc Shareholders Record Time will qualify to receive New Shares and Warrants if the Corp Scheme becomes effective. Only these options can be described as in the money. The only two alternatives for plc are a restructuring under which all its assets are distributed to its creditors or an insolvent administration or liquidation. The reason why plc Shares are trading between 1.5-2.5 pence per share is that only 0.5 per cent. of the New Shares that are to be issued (assuming the Corp Scheme becomes effective and the First Initial Distribution takes place), are being made available to the plc Shareholders as at the plc Shareholders Record Time. THE RETENTION AND EMERGENCE PLAN In order to retain key employees during the restructuring of the Group, a Retention and Emergence plan (the "R&E Plan") was implemented in May 2002 for sixty-three employees. Corp was not a party to any of the documents. Of the sixty-three individuals, Marconi Communications Limited is the responsible Group company for thirty-seven, Marconi Communications, Inc. for seventeen, plc for two (one in Australia and one in Hong Kong), Marconi Communications GmbH for four and Marconi Communications SpA for three. The obligations of plc are to be transferred to Marconi Communications Limited in relation to the two employees whose promise refers to plc. The R&E Plan promises four equal payments to the employees if they are still employed and not working their notices on each payment date. Two of the payment dates have passed and the remaining dates are (i) seven working days after plc completes its refinancing negotiations (with a long stop date of 31 March 2003) and (ii) three months after the third payment date. The aggregate of the payments in each case is based on a percentage of the employee's salary, with the range of percentages varying from 30 per cent. to 150 per cent., depending on the employee's seniority. Those employees who are signing new service agreements and who are in the Management Plan (as defined below) are to waive the last payment due under the R&E Plan. IMPACT OF THE PROPOSED RESTRUCTURING: Nil-cost Option Plans The Marconi Launch Share Plan Options were granted to Participants of this plan as nil cost options. If not currently exercisable, they will become exercisable on a solvent liquidation of plc. At that time Participants will be deemed to have exercised options to acquire the number of plc Shares the plc Board determines. It is anticipated that, due to the Group's financial position, the plc Board will decide that no options should become exercisable. These options will lapse on the tenth anniversary of their date of grant. The Marconi Welcome Plan Options were granted to Participants of this Plan as nil cost options. If not currently exercisable, they will become exercisable on a solvent liquidation of plc. At that time Participants will be deemed to have exercised options to acquire the number of plc Shares the plc Board determines. It is anticipated that, due to the Group's financial position, the plc Board will decide that no options should become exercisable. These options will lapse on the tenth anniversary of their date of grant. The Long Term Incentive Plan (the "LTIP") Nil-cost share options granted under the LTIP which are not currently exercisable will become exercisable when Corp ceases to be a subsidiary of plc. The remuneration committee also has discretion to decide to what extent grants of further nil-cost options should be made at that point. It is anticipated that, given the Group's financial position, the remuneration committee will decide that no further options should be granted. The remuneration committee also has discretion to decide when options, if not exercised, should lapse. 115

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- The Restricted Share Plan (the "RSP") Participants may acquire plc Shares that will be awarded to them when Corp ceases to be a subsidiary of plc. Participants will have six months to call for the shares before the awards lapse. Under the "nil cost" plans, options are currently exercisable or may ordinarily become exercisable before the plc Shareholders Record Time over the following number of plc Shares: <Table> <Caption> Plan Approximate No. of plc Shares ---- ----------------------------- <S> <C> Launch Plan 0 Welcome Plan 0 LTIP 480,000 RSP 910,000 --------- 1,390,000 ========= </Table> As pointed out above, by the time that the remaining outstanding "nil cost" options become exercisable, the shares in plc will have ceased to be of any value. The MET currently holds in the region of 1,208,545 plc Shares and approximately L4,544.58 in cash. The GEC Employee Share Trust currently holds in the region of 1,135,644 plc Shares and approximately L937.45 in cash. Underwater Option Plans The GEC Managers' 1984 Share Option Scheme All outstanding options will become exercisable when the court sanctions the plc Scheme and lapse six months later. The GEC Employee 1992 Savings Related Share Option Scheme All outstanding options will become exercisable when the court sanctions the plc Scheme and lapse six months later. The Marconi 1999 Stock Option Plan Option holders may exercise their options within a period of six months from when Corp ceases to be a Subsidiary of plc at the end of which time unexercised options will lapse. The Marconi UK Sharesave Plan All outstanding options will become exercisable when the court sanctions the plc Scheme and lapse six months later. The Marconi International Sharesave Plan All outstanding options will become exercisable when the court sanctions the plc Scheme and lapse six months later. The GEC 1997 Executive Share Option Scheme Option holders may exercise options within a period of six months from when Corp ceases to be a Subsidiary of plc at the end of which time unexercised options will lapse. The Mobile Systems International Share Option Plan All outstanding options will become exercisable when the court sanctions the plc Scheme and lapse six months later. Metapath Software Corporation 1995 Stock Option Plan Option holders may exercise their options to the extent that performance criteria have been met when the proposal for the solvent liquidation of plc is adopted. Metapath Software International Inc. 1999 Stock Option Plan Option holders may be given the opportunity to exercise vested and non-vested options until five days before a liquidation. All unexercised options will lapse immediately before a liquidation. Mariposa Technology Inc 1998 Employee Incentive Plan All outstanding options held by employees, directors and consultants will become exercisable before an event such as a liquidation and, if not exercised will lapse before such an event. Northwood Technologies Inc. Share Option Plan All outstanding options will remain unaffected by the plc Scheme and will lapse in due case. 116

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- The Marconi Phantom Option Scheme Options will lapse and cease to be exercisable when Corp ceases to be a Subsidiary of plc. The GEC Phantom Option Scheme Options will lapse and cease to be exercisable when Corp ceases to be a Subsidiary of plc. The Marconi Employee Stock Purchase Plan for Employees in North America This plan has been suspended. There are no outstanding options or awards under it. EMPLOYEE INCENTIVE PLANS POST RESTRUCTURING Conditionally on the later of the First Initial Distribution under the Corp Scheme being initiated and the Effective Date (for the purpose of this Part D.10, the "Plans Start Date"), Corp has adopted an option plan known as the Corp Senior Management Share Option Plan (the "Management Plan") and a broadly based employee share option plan known as the Corp Employee Share Option Plan (the "Employee Plan"). The Plans are summarised below. Other than the Group's existing bonus plan arrangements, which cover the financial year to 31 March 2003, and the third payment under the R&E Plan (described above), prior to the Plans Start Date, the Group will not establish any bonus arrangement or scheme or any long term incentive scheme covering those persons (other than those persons who are eligible to receive commission and/or bonus payments that relate to sales) who have been invited to participate in the Management Plan. Further, as set out in Appendix 14, paragraph g (iv), Corp's Articles provide that participants in the Management Plan (other than those who are eligible to receive commission and/or bonus payments that relate to sales) will not be eligible to participate in any bonus or other long-term incentive arrangement until the date on which all the tranches in the initial grant under the Management Plan have either lapsed or become capable of exercise. The Corp Senior Management Share Option Plan Administration The Management Plan will be administered by the remuneration committee of Corp in accordance with the terms set out below. Eligibility Participation in the Management Plan is open to those employees and executive directors of Corp or any of its Subsidiaries selected by the remuneration committee. The remuneration committee intends to grant options under the Management Plan to up to 60 senior executives. Employees within two years of their normal retirement date may not participate in the Management Plan. Grant of options Options to acquire Corp shares under the Management Plan may be granted at any time prior to the Listing of the New Shares and, following Listing of the New Shares, may be granted in the periods of 42 days commencing on the Plans Start Date, the day immediately following announcement by Corp of its results for any period, or a day on which the Board resolves that exceptional circumstances exist which justify the grant. Options will be granted by either Corp or the trustee of the proposed Corp employee benefit trust (the "Trust") summarised below. Options may be satisfied using newly issued or existing Corp Shares. The initial options will be granted in five tranches, each of which will be subject to different performance conditions as described below. Participation in the Management Plan will not form part of or affect a participant's right under the terms of his employment. 117

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Option exercise price Options granted under the Management Plan will be exercisable for a nominal payment, the amount of which will be determined by the remuneration committee. It is currently envisaged that the total amount payable on the exercise of an option, whether in whole or in part will be L1 per exercise irrespective of the number of New Shares the subject of an option exercise. Individual limit on participation There is no limit under the Management Plan on the aggregate maximum value of options which may be granted to a participant in any year or over the life of the Management Plan. Overall limit on Corp Shares to be made available under the Management Plan The number of Corp Shares, issued or unissued, that may be committed under the Management Plan is limited to 9 per cent. of the issued share capital of Corp immediately following the Plans Start Date. Corp Shares over which options have lapsed or been surrendered will not be included in calculating this limit. This number of shares will be reduced by the number of Corp Shares that are committed under the Employee Plan due to employees who would otherwise have been expected to participate in the Management Plan participating in the Employee Plan rather than the Management Plan because it is beneficial (for tax or similar reasons) for them to do so. Exercise of Options Options granted under the Management Plan will only become exercisable (vest) to the extent that the performance targets set out below have been satisfied. While the performance targets for the initial grant of options will be the same, two vesting schedules will apply; one schedule applicable to participants who have released their rights under the R&E Plan (described above) and the other schedule applicable to participants who did not have any rights under the R&E Plan. For subsequent grants, for example, to new employees or as a result of promotions or expanded roles or responsibilities, the remuneration committee will set performance targets which are appropriate in the circumstances and at least as challenging as those for the initial grant. <Table> <Caption> Percentage of shares subject to option that vest (per cent.) ----------------------------------------------- Participants who released R&E Other Tranche Condition Plan rights* Participants ------- ------------------------------------------ ---------------------- ---------------------- <S> <C> <C> <C> 1. Repayment of 30 per cent. of the New 20 10 Junior Notes within 24 months after the Plans Start Date. No vesting before 12 months after the Plans Start Date. 2. Repayment of 50 per cent. of the New 10 10 Junior Notes within 27 months after the Plans Start Date. No vesting before 15 months after the Plans Start Date. 3. Repayment of 100 per cent. of the New 20 20 Junior Notes within 30 months after the Plans Start Date. No vesting before 18 months after the Plans Start Date. 4. Corp achieving a market capitalisation of 20 30 L1 billion and repayment of 100 per cent. of the New Junior Notes within 39 months after the Plans Start Date. No vesting before 27 months after the Plans Start Date. </Table> 118

No vesting before 39 months after the Plans Start Date. (between 51 months and (between 51 months and 63 months of the Plans 63 months of the Plans Start Date) Start Date) 20 20 </Table> * Participants in the R&E Plan will be required to waive the final payment under the R&E Plan in order to participate in the Management Plan. If any performance target is not satisfied within the stated period the tranche of the option subject to that performance target will lapse and cease to be capable of becoming exercisable. If the New Junior Notes are refinanced (rather than repaid), the conditions set out above will apply to the aggregate debt, representing what were the New Junior Notes, following the refinancing. In relation to tranches 4 and 5, the market capitalisation of Corp will be measured using its daily volume weighted average share price determined from prices quoted on the principal exchange on which Corp Shares are listed and the number of Corp Shares outstanding immediately following the Plans Start Date. In order to determine if the relevant condition is satisfied, the daily volume weighted average share price will be obtained for each day of a rolling 90 day period and the average price over that 90 day period will be determined. If that average price when multiplied by the number of Corp Shares in issue on the Plans Start Date exceeds the relevant target market capitalisation, the applicable condition will have been satisfied. Taxation The exercise of an option may be made conditional on a participant agreeing to comply with any arrangements specified by Corp for the payment of taxation, social security contributions or any other deductions at source (including, as is likely to be the case, in respect of at least part of the relevant employing company's secondary class 1 National Insurance contributions liability arising on exercise) required or permitted in respect of an option. Termination of employment If a participant ceases employment with a member of the Corp Group voluntarily or he is dismissed for cause, his options will lapse on the date of cessation. However, where a participant ceases employment with the Group due to death, injury, disability, ill-health, redundancy, retirement or the sale of the business or subsidiary for which the participant works, or termination of employment by the employer without cause, his options will become vested to the extent the financial performance conditions have been satisfied at the date of cessation of employment (or, if terminated without full notice, to the extent the financial performance conditions have been satisfied on the date the notice would have expired) and will become exercisable at the time they would otherwise have been exercisable as set out in the table above for a period of 6 months (12 months in the case of death). The remuneration committee may decide whether a different proportion of an option should vest on the cessation of employment of any participant due to the sale of a business or subsidiary that was a key business or subsidiary. Following the expiry of the relevant period, all of a participant's unexercised options will lapse. 119

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Lapse of options Options will lapse in any event on the tenth anniversary of their grant and will lapse after a takeover or reconstruction when the specified time periods for exercise have passed as described below. Options will also lapse on the cessation of employment of a participant as described above. Options will also lapse to the extent that they cease to be capable of becoming exercisable due to failure to satisfy any of the performance targets within the specified time periods. Corp Shares over which options have lapsed or have been surrendered will be available, within the overall limit referred to above, to form the subject of further option grants to new participants in the Management Plan but not to existing participants unless the participant has been promoted or his/her role and/or responsibility has significantly expanded and the remuneration committee determines that such a grant is merited. Rights attaching to Corp Shares on the exercise of options Corp Shares allotted under the Management Plan will carry the same rights as all other issued Corp Shares. Application will be made for the Corp Shares to be admitted to trading on the London Stock Exchange. Participants will not qualify for any rights attaching to Corp Shares where the record date is before the date on which the option is exercised. Takeover, reconstruction or winding-up If any person obtains control of Corp as a result of making an offer to acquire the whole of the issued share capital of Corp (or, having such control, makes a general offer to acquire all the shares other than those already owned by that person) the first grant of options under the Management Plan will become exercisable to the extent that the financial performance conditions have been satisfied immediately prior to a change of control. A proportion of the remainder of any Corp Shares which are the subject of outstanding options under the initial grant will vest and become exercisable according to the following formula: <Table> <S> <C> <C> market capitalisation on change of control (as evidenced by the value of the consideration paid by the acquirer and the number of Corp Shares in issue remainder of Corp Shares the subject of immediately following the Plans Start outstanding options X Date) ---------------------------------------- L1.5 billion </Table> The formula above assumes that a change of control occurs 63 months after the Plans Start Date. If a change of control occurs sooner, to reflect the benefit to shareholders of the early release of funds, the L1.5 billion figure will be reduced by L25m for each complete quarter between the change of control and the date which is 63 months after the Plans Start Date. Participants will have six months within which to exercise their options to the extent exercisable following the change of control (or general offer); thereafter, the options will lapse. The remuneration committee will determine the extent to which any subsequent options will vest in the event of a takeover, having regard to the performance targets to which those options are subject. If a person becomes bound or entitled to give notice to acquire Corp Shares under sections 428 to 430F of the Act, a participant may exercise his options to the extent exercisable as referred to above during the period that person remains so bound or entitled; thereafter, they will lapse. Participants may, in certain circumstances, be given the opportunity to exchange their options for options over ordinary shares in an acquiring company. If there is a reconstruction of Corp, the effect of which is that a person obtains control of Corp, other than as a result of making an offer for its issued share capital, the provisions relating to a change of control following an offer (summarised above) shall apply. These provisions shall not apply if there is a reconstruction, the purpose and effect of which is to create a new holding company of Corp where such holding company has substantially the same shareholders and proportionate shareholdings as those of Corp immediately before the scheme of 120

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- arrangement. On the occurrence of such a reconstruction, the remuneration committee will use its best endeavours to ensure that any outstanding options are rolled-over so that they continue over shares in the new holding company. If there is no roll-over, options will continue unaffected by the scheme of arrangement. If there is any other reconstruction of Corp or Corp is wound-up, options will lapse on the reconstruction or winding-up taking effect. Adjustments of options If there is a variation in the share capital of Corp, including by way of a capitalisation, rights issue, consolidation, sub-division, reduction or any other variation or the implementation by Corp of a demerger or payment of a super-dividend which would materially affect the value of options under the Management Plan, the remuneration committee may (subject to the auditors' approval) make the adjustments it considers appropriate to the number of Corp shares under option. Amending the Management Plan The rules of the Management Plan can be amended at any time by the Board, provided that no amendment to the Management Plan can be made without the prior approval of Corp in a general meeting of shareholders if the amendment relates to the provisions in the rules relating to eligibility, limits on the number of Corp Shares available for issue under the Management Plan, the basis for determining a participant's entitlement to Corp Shares and any adjustment in the event of a variation in the share capital of Corp. In addition, no amendment that would materially prejudice the interests of existing participants may be made without the prior consent of participants holding three-quarters of the aggregate number of shares subject to the outstanding options. Participants in the United States For participants in the United States, the Management Plan will be structured as a conditional right to receive Corp Shares or ADRs (an "Award") rather than as an option, for tax purposes. No price will be payable by participants on the vesting of their Awards. Awards will not vest during a close or prohibited period. Awards will be subject to the same performance conditions and other terms set out above. General Participation in the Management Plan is not pensionable. Options granted under it are not transferable and may only be exercised by the person to whom they were granted or their personal representatives. No options can be granted under the Management Plan more than five years after the Plans Start Date. Summary of the Corp Employee Share Option Plan Administration The Employee Plan will be administered by the remuneration committee of Corp in accordance with the terms set out below. Eligibility Participation in the Employee Plan is open to those employees and executive directors of Corp or any of its Subsidiaries selected by the remuneration committee. Employees within two years of their normal retirement date may not participate in the Employee Plan. Employees who participate in the Management Plan cannot participate in the Employee Plan. Grant of options Options to acquire Corp Shares under the Employee Plan will be granted by either Corp or the trustee of the Trust. Options may be satisfied using newly issued or existing Corp Shares. Inland Revenue approved options and non-Inland Revenue approved options ("Unapproved Options") may be granted under the Employee Plan. 121

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Following Listing of the New Shares options may be granted in the periods of 42 days commencing on the Plans Start Date, the day immediately following announcement by Corp of its results for any period, or a day on which the Board resolves that exceptional circumstances exist which justify the grants. The Corp Board will not grant any options under the Employee Plan until 30 business days after Listing of the New Shares. The exercise price for such initial grant of options shall be the average middle market quotation of a Corp Share for the five business days immediately prior to the date of grant. The initial options will be granted in five tranches, each of which will be subject to different performance conditions as described below. Participation in the Employee Plan will not form part of or affect a participant's rights under the terms of his employment. The following is a summary of the provisions which apply equally to Approved Options and Unapproved Options. Option exercise price The exercise price of options will be determined by the remuneration committee but will not be less than the middle market quotation of a Corp share as derived from the London Stock Exchange Daily Official List on a date (or dates in the case of an average quotation) not more than 30 days prior to the date of grant of the option (or such other period as the Inland Revenue may agree in relation to Approved Options). Where an option is to subscribe for Corp Shares, the exercise price will not be less than the nominal value of a Corp Share. Individual Limit on participation There is no limit under the Employee Plan on the aggregate maximum value of options which may be granted to a participant in any year or in the life of the Employee Plan (subject, in the case of Approved Options, to the statutory limit described below). Overall limit on Corp Shares to be made available under the Employee Plan The number of Corp Shares, issued or unissued, that may be committed under the Employee Plan is limited to 5 per cent. of the issued share capital of Corp immediately following the Plans Start Date. The limit does not include share capital committed pursuant to any other employees' share plan previously adopted by Corp. This number of shares will be increased, with a corresponding reduction in the number of Corp Shares available to be committed under the Management Plan, if any employee who would otherwise have been expected to participate in the Management Plan participates in the Employee Plan rather than the Management Plan because it is beneficial (for tax or similar reasons) for them to do so. This 5 per cent. limit will only be available for use on the following basis:(i) 3 per cent. in the first 12 months following Listing of the New Shares; (ii) 1 per cent. in the second 12 months following Listing of the New Shares; and (iii) 1 per cent. in the third 12 months following Listing of the New Shares. Any unused part of this limit may be utilised in subsequent years during the life of the Employee Plan. Corp Shares over which options have lapsed or been surrendered will not be included in calculating this limit. 122

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Exercise of Options Options granted under the Employee Plan will only become exercisable to the extent that the performance targets to which they are subject have been satisfied. The performance targets for the first grant of options are set out below. For subsequent grants, the remuneration committee will set performance targets which are appropriate in the circumstances and at least as challenging as those for the initial grant. Performance targets <Table> <Caption> Percentage of shares subject Tranche Condition to option that vest (per cent.) ------- ---------------------------------------- ---------------------------------------- <S> <C> <C> 1. Repayment of 30 per cent. of the New 10 Junior Notes within 24 months after the Plans Start Date. No vesting before 12 months after the Plans Start Date. 2. Repayment of 50 per cent. of the New 10 Junior Notes within 27 months after the Plans Start Date. No vesting before 15 months after the Plans Start Date. 3. Repayment of 100 per cent. of the New 20 Junior Notes within 30 months after the Plans Start Date. No vesting before 18 months after the Plans Start Date. 4. Corp achieving a market capitalisation 30 of L1 billion and repayment of 100 per cent. of the New Junior Notes within 39 months after the Plans Start Date. No vesting before 27 months after the Plans Start Date. 5. Corp achieving a market capitalisation (within 51 months of the Plans Start of L1.5 billion and repayment of 100 per Date) cent. of the New Junior Notes within 63 30 months after the Plans Start Date. No vesting before 39 months after the Plans (between 51 months and 63 months of the Start Date. Plans Start Date) 20 </Table> If any performance target is not satisfied within the stated period the tranche of the option subject to that performance target will lapse and cease to be capable of becoming exercisable. If the New Junior Notes are refinanced (rather than repaid), the conditions set out above will apply to the aggregate debt, representing what were the New Junior Notes, following the refinancing. In relation to tranches 4 and 5, the market capitalisation of Corp will be measured using its daily volume weighted average share price determined from prices quoted on the principal exchange on which Corp's Shares are listed and the number of Corp Shares outstanding immediately following the Plans Start Date. In order to determine if the relevant condition is satisfied, the daily volume weighted average share price will be obtained for each day of a rolling 90 day period and the average price over that 90 day period will be determined. If that average price when multiplied by the number of Corp Shares in issue on the Plans Start Date exceeds the relevant target market capitalisation the applicable condition will have been satisfied. Taxation The exercise of an Unapproved Option may be made conditional upon a participant agreeing to comply with any arrangements specified by Corp for the payment of taxation, social security contributions or any other deductions at source (including, as is likely to be the case, in respect of at least part of the relevant employing company's 123

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- secondary class 1 National Insurance contributions liability arising on exercise) required or permitted in respect of an option. Termination of employment If a participant ceases employment with a member of the Corp Group voluntarily or he is dismissed for cause, his unvested options will lapse on the date of cessation. However, where a participant ceases employment with the Corp Group due to death, injury, disability, ill-health, redundancy, retirement or the sale of the business or subsidiary for which the participant works, or termination of employment by the employer without cause, his options will become vested to the extent the financial performance conditions have been satisfied at the date of cessation of employment (or, if terminated without full notice, to the extent the financial performance conditions have been satisfied on the date notice would have expired) and will become exercisable at the time they would otherwise have been exercisable as set out in the table above for a period of 6 months (12 months in the case of death). The remuneration committee may decide whether a different proportion of an option should vest on the cessation of employment of any participant due to the sale of a business or subsidiary that was a key business or subsidiary. Following the expiry of the relevant period, all of a participant's unexercised options will lapse. Lapse of options Options will lapse in any event on the tenth anniversary of their grant and will lapse after a takeover or reconstruction when the specified time periods for exercise have passed as described below. Options will also lapse on the cessation of employment of a participant as described above. Options will also lapse to the extent that they cease to be capable of becoming exercisable due to the failure to satisfy any of the performance targets within the specified time periods. Rights attaching to Corp Shares on the exercise of options Corp Shares allotted under the Employee Plan will carry the same rights as all other issued Corp Shares. Application will be made for the Corp Shares to be admitted to trading on the London Stock Exchange. Participants will not qualify for any rights attaching to Corp Shares where the record date is before the date on which the option is exercised. Takeover, reconstruction or winding-up If any person obtains control of Corp as a result of making an offer to acquire the whole of the issued share capital of Corp (or, having such control, makes a general offer to acquire all the shares other than those already owned by that person) the first grant of options under the Employee Plan will become exercisable to the extent that the financial performance conditions have been satisfied immediately prior to a change of control. A proportion of the remainder of any Corp Shares which are the subject of outstanding options will vest and become exercisable according to the following formula: <Table> <S> <C> <C> market capitalisation on change of control (as evidenced by the value of the consideration paid by the acquirer and the number of Corp Shares in issue remainder of Corp Shares the subject of immediately following the Plans Start outstanding options x Date) ---------------------------------------- L1.5 billion </Table> The formula above assumes that a change of control occurs 63 months after the Plans Start Date. If a change of control occurs sooner, to reflect the benefit to shareholders of the early release of funds, the L1.5 billion figure will be reduced by L25m for each complete quarter between the change of control and the date which is 63 months after the Plans Start Date. Participants will have six months within which to exercise their options to the extent exercisable, following the change of control (or general offer); thereafter, the options will lapse. The remuneration committee will 124

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- determine the extent to which any subsequent options will vest in the event of a takeover, having regard to the performance targets to which those options are subject. If a person becomes bound or entitled to give notice to acquire Corp Shares under sections 428 to 430F of the Act, a Participant may exercise his options to the extent exercisable as referred to above during the period when that person remains so bound or entitled; thereafter, they will lapse. Participants may, in certain circumstances, be given the opportunity to exchange their options for options over ordinary shares in an acquiring company. If there is a reconstruction of Corp, the effect of which is that a person obtains control of Corp, other than as a result of making an offer for its issued share capital, the provisions relating to a change of control following an offer (summarised above) shall apply. These provisions shall not apply if there is a reconstruction, the purpose and effect of which is to create a new holding company of Corp where such holding company has substantially the same shareholders and proportionate shareholdings as those of Corp immediately before the scheme of arrangement. On the occurrence of such a reconstruction, the remuneration committee will use its best endeavours to ensure that any outstanding options are rolled-over so that they continue over shares in the new holding company. If there is no roll-over, options will continue unaffected by the scheme of arrangement. If there is any other reconstruction of Corp or Corp is wound-up, options will lapse on the reconstruction or winding-up taking effect. Adjustments of options If there is a variation in the share capital of Corp, including by way of a capitalisation, rights issue, consolidation, sub-division, reduction or any other variation or the implementation by Corp of a demerger or payment of a super-dividend which would materially affect the value of options under the Employee Plan, the remuneration committee may (subject to the auditors' approval and, in the case of Approved Options, to the approval of the Inland Revenue) make the adjustments it considers appropriate to the number of Corp Shares under option and the exercise price. Amending the Employee Plan The rules of the Employee Plan can be amended at any time by the Board, provided that no amendment to the Employee Plan can be made without the prior approval of Corp in a general meeting of shareholders if the amendment relates to the provisions in the rules relating to eligibility, limits on the number of Corp Shares available for issue under the Employee Plan, the basis for determining a participant's entitlement to Corp Shares and any adjustment in the event of a variation in the share capital of Corp. In addition, no amendment that would materially prejudice the interests of existing participants may be made without the prior consent of participants holding three-quarters of the aggregate number of shares subject to outstanding options. For these purposes, the interests of the holders of Approved Options and Unapproved Options are separate. Participants in the United States For participants in the United States, the Employee Plan will be structured as a qualifying incentive stock option plan and a non-qualifying stock option plan over Corp Shares or ADRs. Options will be granted on the same terms and will be subject to the same performance conditions as described above, save any changes necessary to take account of the relevant United States legislation. General Additional schedules to the rules of the Employee Plan can be established to operate the Employee Plan in overseas countries. These schedules can vary the rules of the Employee Plan to take account of any securities, exchange control, or taxation laws or regulations for any participants or any company in the Group. Any Corp Shares issued under such schedules will count towards overall limits under the Employee Plan. Participation in the Employee Plan is not pensionable. Options granted under it are not transferable and may only be exercised by the persons to whom they were granted or their personal representatives. 125

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- No options can be granted under the Employee Plan more than five years after the Plans Start Date. Provisions relating to Approved Options Approved Options are those options granted under the Employee Plan which satisfy the requirements of Schedule 9 to ICTA 1988 (or any replacement legislation). The main differences between Approved Options and Unapproved Options are that: (a) No Approved Option can be granted to a participant who is ineligible to participate in the Employee Plan by virtue of paragraph 8 of Schedule 9 (material interest in a close company) ICTA 1988 (or any replacement legislation). (b) An employee cannot be granted an Approved Option which would, at the time it is granted, enable the employee to acquire Corp shares under option schemes approved under Schedule 9 ICTA 1988 (or any replacement legislation) (which are not savings-related) having a value (calculated on the relevant date of grant) exceeding the Inland Revenue limit (currently L30,000). (c) Any amendment to the rules of the approved part of the Employee Plan requires the prior approval of the Inland Revenue. (d) There are circumstances (principally where a participant's employment ceases in compassionate circumstances) when the remuneration committee can extend the period in which Approved Options may be exercised in order that the Participant may qualify for tax relief on exercise of the Approved Option. Application will be made to the Inland Revenue for approval of that part of the Employee Plan under which Approved Options may be granted. Proposed Sharesave Plan Subject to obtaining the prior approval of Corp's shareholders, Corp intends to establish a sharesave plan (or a similar plan, taking into account any changes in market practice and the relevant legislation) at a later date. Such a plan will be varied for overseas participants to take account of local legislation. In the United States, the plan will be an approved stock purchase plan (or a similar plan, taking into account any changes in market practice and the relevant US legislation). The Trust The Trust will be established by a trust deed entered into between Corp and an independent trustee resident in Jersey. The Trust will be a discretionary trust for the benefit of employees and former employees (and their dependants) of the Corp Group (the "Beneficiaries"). Corp has the power to appoint and remove the Trustee. The Trustee will be entitled to subscribe for or otherwise acquire Corp Shares for the benefit of Beneficiaries and will be able to distribute these Corp Shares under the terms of the Trust either directly or in accordance with the rules of any employees' share schemes established by Corp. The Trustee will not be permitted to enter into any forward swap derivative arrangements. It is intended that the Trust may be funded by any person or company including Corp or any company in the Corp Group by means of gift, loan or otherwise. The limit on the number of Corp Shares which can be acquired by the Trustee (whether by market purchase or subscription) will be that set out in the rules of the relevant share incentive plan. It is intended that the terms of the Trust will be amended at the discretion of the Trustee and with the consent of Corp. Corp will not be entitled to consent to any amendment to the advantage of Beneficiaries without the prior approval of Corp in general meeting unless the amendment is minor to benefit the administration of the Trust, to take account of any changes in legislation or to obtain or to maintain favourable taxation, exchange control or regulatory treatment for any Beneficiary of Corp or any company in the Corp Group. 126

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- ABI GUIDELINES The extent to which the Plans comply with the ABI's published guidelines for share incentive plans (the "Guidelines") is summarised below. Overview: The Plans are not totally compliant with the Guidelines. The design of the Management Plan, which is the least compliant (while being the most important from Corp's perspective), has been driven by the importance of ensuring that the senior management team remains in place and is suitably incentivised. It is also designed to compensate for and replace existing bonus arrangements and amendments to individuals' terms of employment (as previously described above). The Scheme Creditors will also in effect, be asked to approve the arrangements as part of approving the Corp Scheme. The Principal Guidelines focus on: a. Performance conditions The ABI requires that performance conditions should emphasise the importance of linking remuneration to performance, align the interests of participating directors and senior executives with those of the shareholders, be demanding and stretching and relate to overall corporate performance. Performance conditions should also be demanding in the context of the prospects of the company and the prevailing economic climate in which the company operates. They should also be disclosed and transparent. The Guidelines also require that the greater the level of potential award, the more stretching and demanding the performance conditions should be. Corp believes that the proposed performance conditions for the discretionary plans are compliant with these requirements. The performance conditions chosen are demanding and are clearly linked to the achievement of enhanced shareholder value. The Guidelines also state that performance should be measured against a peer group or benchmark. Given the nature of the targets and the position of Corp, this is not practicable. b. Change of control provisions The Guidelines state that there should be no automatic waiver of performance conditions on a change of control. They also state that options should vest on a pro-rata basis taking into account the vesting period that elapsed at the time of the change of control though making due allowance for the reduction in value resulting from the reduced life of the option. Tranches of options will only vest if the financial performance conditions applicable to them have been satisfied. The level of additional vesting is dependent upon Corp's market capitalisation on change of control, as summarised above. In essence, therefore, Corp believes the Plans are compliant. c. Dilution limits The Guidelines provide that not more than 10 per cent. of the issued ordinary share capital of a company can be committed to be issued to satisfy share options/awards under all of its share plans in any rolling 10 year period. It is currently proposed that the number of unissued shares that may be committed to be issued in the 5 years following the Plans Start Date will be 9 per cent. of the issued share capital of Corp under the Management Plan and 5 per cent. under the Employee Plan. The Guidelines also encourage phased grants (generally on an annual basis to spread the dilution over the life of the plan). No requirement for phased granting is included in the Plans. The adoption of the Management Plan to incentivise management in these circumstances is very much regarded as a one-off arrangement. 127

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- d. Participation Participation in the Plans is limited to bona fide employees and executive directors. This is compliant with the Guidelines. However, there are no limits on individual participation. Corp considers this to be justifiable as option grants must be of a level to retain and motivate participants who are being asked in some cases, to waive existing entitlements to a bonus and amend the terms of their contracts of employments, as stated above. Participants who are granted an option under the Management Plan cannot participate in the Employee Plan. e. Exercise price The Guidelines state that options should not be granted at a discount. Under the Management Plan, only a nominal sum will be payable on the exercise of options. The Employee Plan will be compliant. As stated above, the Management Plan has been designed to ensure that senior management remains in place and suitably incentivised. In order to achieve this, the necessary levels of potential gain make it more efficient to grant options with an exercise price set at a discount rather than at the prevailing market value (on the day the options are granted) as fewer Corp Shares are required. f. Timing of grant The Plans are compliant with the Guidelines -- following Listing of the New Shares, grants can only normally be made within the 42 day period following the announcement of Corp's results. g. Life of Plans and incentive awards The Guidelines state that the life of plans should not exceed 10 years and that options should not be exercisable within 3 years of grant. The Plans have a five year life. Under the terms of the Management Plan and the Employee Plan, options may be exercised in part after 12, 15, 18, 27 and 39 months following the Plans Start Date. In accordance with the Guidelines, no option can be exercised more than 10 years following its grant. h. Retirement The Guidelines require that options should not be granted to a participant within 6 months of his/her anticipated retirement date. The Management/Employee Plans will provide that options cannot be granted to a participant within 2 years of his/her anticipated retirement date. Where options are granted to a participant within 3 years of his/her anticipated retirement date, the remuneration committee will have regard to the executive's ability to contribute to the satisfaction of the performance conditions, in accordance with the Guidelines. i. Personal shareholding requirements The Guidelines require that the rules of incentive plans should incorporate the requirement to retain a significant proportion of the shares to which participants become entitled. The Guidelines state that this is particularly important in the case of awards where performance conditions apply principally at the point of grant of an option. Given the nature of the performance conditions which apply to the initial grants of options under the Management Plan and the Employee Plan and the fact that they must be satisfied prior to exercise, rather than grant, a personal shareholding requirement is not considered necessary. 128

EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- j. Non-Executive Directors As described in Part E.1, in accordance with the Guidelines, the Non-Executive Directors (other than the Chairman) will acquire Corp Shares out of their net fees at a price equal to the prevailing market value on the date of acquisition. D.11 PENSIONS Claims under this section are excluded from the Corp Scheme and, to the extent that claims are preferential or otherwise incapable of being schemed, from the plc Scheme. Please refer to Appendix 9 for fuller details of the exclusions. UNITED KINGDOM PENSION SCHEMES Description of the main scheme The GEC 1972 Pension Plan (the "UK Plan") is the principal tax-exempt approved occupational pension scheme in the United Kingdom in respect of which Corp Group or any of its group companies has any liabilities (and the only one in respect of which Corp has any liabilities). Employee contributions are 3 per cent. of pensionable earnings with employers paying the balance of the cost. The UK Plan's principal employer is Corp but Group companies participate and are responsible for their own contributions. The executive directors of Corp and plc are members (or entitled to be members of) of the UK Plan. There are other UK pension arrangements and these are described below. Corp and the other group companies and the UK Plan trustee have complied with their legal obligations in respect of the UK Plan and the unapproved pension arrangements Corp is not aware of any current or threatened material claim against it, any member of the Group or the trustees in respect of the UK Plan or in relation to any benefits provided on retirement, death or termination of service. Funding of the UK Plan The scheme actuary has carried out the statutory, triennial Minimum Funding Requirement ("MFR") valuation (as at 5 April 2002) and on 6 February 2003 signed his report. The report states that the UK Plan was (as at the valuation date) between 115 and 120 per cent. funded on an MFR basis. This means that no statutory minimum company contributions are currently required to be paid. On the UK Plan's own ongoing funding basis, the report states that the UK Plan is 100 per cent. funded as at 5 April 2002. Please note that the funding level may have changed since 5 April 2002, particularly having regard to falls in equity markets and the UK Plan could currently be underfunded on an ongoing basis. Corp makes contributions at the rate of 8.2 per cent. of pensionable earnings (having started in November 2002). The contribution rate is expected to remain at 8.2 per cent. of pensionable earnings. The employee contribution rate will remain at 3 per cent. of pensionable earnings. The report states that if the UK Plan had been discontinued at the date of the valuation in April 2002 and wound up, there would have been insufficient assets (by a considerable margin) to provide accrued benefits by the purchase of annuity policies. Nevertheless, the valuation did not indicate that a statutory debt under section 75 of the Pensions Act 1995 would be placed on Corp if the UK Plan were wound up and the debt calculation performed as at that date. This position could alter if the debt calculation is carried out as at a later date, as a consequence of a number of factors, including a change in the Statement of Investment Principles of the UK Plan, the investment performance of its assets, the estimated cost of annuities and the level of retirements within the UK Plan. No winding up has so far been triggered in relation to the UK Plan. If a winding up of the UK Plan were to be triggered in the future, the UK Plan trustee would be able to determine the date on which any statutory debt would be calculated by the actuary to the UK Plan. The amount of any debt depends on a number of factors, including the investment strategy which has been adopted by the trustee in the UK Plan's statement of investment principles and the value of the assets and liabilities of the UK Plan at the date of the calculation. If a section 75 debt were to arise, the size of the debt (relative to Corp's assets) could have a materially detrimental effect on Corp's resources. The materiality of the detrimental effect on Corp's reserves is shown by the fact that the 129

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- actuarial valuation stated that (as at 5 April 2002) the UK Plan has assets of approximately L2.495 billion and liabilities (calculated on an ongoing basis) of approximately L2.494 billion. On the winding up of a pension plan, the applicable statute values the benefits of the members by reference to a stricter test than the MFR valuation (for example, pensioner liabilities are valued on a buy-out basis) and the sponsoring employer is liable to make good any deficit. There is no guarantee that the value of the UK Plan's assets will not deteriorate nor that legislation will not be introduced to oblige employers to make further contributions to pension plans which are not fully funded, in addition to current statutory obligations. The UK Government presented a Green Paper on pension reform on 17 December 2002 which could lead to further legislation on, amongst other issues, the obligations on employers to make good pension scheme deficits, principally by replacing the MFR with a scheme-specific minimum funding level. See below for the impact on funding if a lower than expected transfer amount is paid under an existing sale agreement. See also Part F.2: Risk Factors. UNAPPROVED UK PENSION PLANS The only other UK retirement and death benefit arrangements in respect of which Corp has any liability in the UK are the following unapproved pension arrangements. a. Funded unapproved retirement benefit schemes for current employees ("FURBS") There are thirteen FURBS for each of thirteen current senior employees. FURBS are top-up pension plans funded in advance in respect of employees who are subject to the earnings cap. The earnings cap is a figure set by the Inland Revenue as the point at which tax relief on contributions ceases and above which benefits from the UK Plan cannot be provided (L97,200 for the 2002/2003 tax year). Ten of the thirteen FURBS are defined contribution arrangements, where the employer pays (depending on the employee/director) an amount equivalent to between 10 and 35 per cent. of earnings in respect of the employee's FURBS. Because an employer's contribution to a FURBS qualifies as a taxable benefit, the employer in fact pays 60 per cent. of its contribution described above to the FURBS and the balance of its contribution to the employee, to cover the extra tax burden. All contributions are up to date. The remaining three FURBS are defined benefit arrangements and they each have intended accrual rates of 3.33 per cent. depending on the value of retained benefits. Mr Donovan's defined benefit FURBS is described in Part E.1. All employees who have a FURBS also have additional life cover that is provided through an unapproved life assurance scheme, for which the employer pays the premium. b. Unfunded unapproved pensions ("UURBS") Corp is currently liable to pay a total annual pension contribution of currently L171,197 to Lady Weinstock under an UURBS established for the late Lord Weinstock. This pension is to increase annually in line with increases to pensions in payment under the UK Plan. Corp was the original promisor of an unfunded top-up pension in 1998 in favour of Anthony Cobbe. Mr Cobbe was promised a pension at age 62 of two-thirds his final pensionable salary, funded from the UK Plan, the GEC-USA Retirement Plan and by Corp itself. The pension is currently in payment but the unfunded element is in fact paid by Marconi Communications Limited, his actual former employer but no formal agreement documenting this arrangement has been made. PENSION INDEMNITIES In sales of subsidiary companies and businesses in recent years, Corp has on some occasions given an indemnity for employer debts which could arise under section 75 of the Pensions Act 1995. If there were an MFR deficit at the point at which the subsidiary or buyer of assets ceased to participate in the UK Plan, section 75 would oblige the subsidiary or buyer to contribute to remedying the deficit. The section 75 indemnity has been given on very 130

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- few occasions and there is no indication that the funding of the UK Plan was below MFR levels at the relevant dates. Accordingly Corp believes that the indemnity is unlikely to be called upon. Following the sale of General Domestic Appliances Holdings Limited in 2001, the trustee of the UK Plan is to make a payment to the buyer's pension plan in respect of the accrued benefits of the employees who transfer to the buyer. Although a basis for calculation of the transfer amount was agreed in the sale agreement for the sale of GDA, the trustee of the UK Plan is not bound by this. Corp is responsible for 50 per cent. of any shortfall between the transfer amount agreed in the sale agreement and the amount actually paid by the trustee. Anticipating a shortfall at the time of the sale, an allowance of L3.255 million was made in the sale price. The information received by Corp to date is that the plan actuary intends to advise the trustee to calculate the transfer amount on the agreed basis, which could (apart from the allowance in the sale price) result in a liability to Corp under the shortfall obligation of approximately L1.47 million. Allowing for the price adjustment, Corp would on these figures be entitled to L1.785 million from the buyer. If the trustee does not follow the advice of the actuary or if the actuary changes his advice, Corp expects its maximum liability under the shortfall obligation to be approximately L14.665 million (or L12.88 million if the net over-allowance by Corp is taken into account). The actuary is not bound by his representations and a final determination of the transfer amount is not likely until April or May, 2003. There can be no assurance that the trustee will not decide to follow a basis which results in greater liability for Corp than Corp currently expects, which could have a material adverse effect on the Group. Indeed, if the trustee refuses or fails to transfer the whole or any part of the agreed amount, Corp will be liable for 50 per cent. of the shortfall (less the buyer's prevailing rate of corporation tax), which could produce a significantly larger liability. If Corp is required to make a net payment of approximately L14.665 million (or L12.88 million if the net over-allowance by Corp is taken into account), the funding position of the UK Plan would improve considerably. This would be because the UK Plan had distributed a smaller than anticipated amount to the buyer's pension plan. UNITED STATES PENSION PLANS Description of the main US plan The principal pension plan in the United States is the Marconi USA Employees' Retirement Plan, which is a tax-qualified, funded defined benefit plan. The following additional plans are also maintained in the US: a. the RELTEC Corporation Retirement Plan, which is a tax-qualified, funded defined benefit plan (the "RELTEC PLAN"). The benefit accruals of participants in the RELTEC Plan were frozen, effective as of 31 December 1997; and b. the RELTEC Supplemental Executive Retirement Plan (the "SERP"), which is an unfunded, non-tax-qualified plan for a select group of management or highly compensated employees. There are approximately seven participants covered by the SERP as of 1 April 2002. The SERP was also frozen as of 31 December 1997. No benefits have accrued under the SERP since that date. Corp is not a sponsoring employer of the Marconi Plan or the RELTEC Plan but, because Corp and plc are part of the plan sponsor's "controlled group" under the Employee Retirement Income Security Act of 1974, as amended ("ERISA") and the Internal Revenue Code of 1986, as amended (the "CODE"), Corp and plc would each be jointly and severally liable under ERISA for any funding shortfall on termination of either plan (together with the US subsidiaries which are participating employers and other substantially owned US and non-US subsidiaries). The sponsor of the Marconi Plan and the RELTEC Plan is a US company, as are each of the participating employers. There is no formal or informal plan or commitment at this time to terminate either the Marconi Plan or the RELTEC Plan. 131

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Funded status of the US plans Corp and plc estimate as at 30 September 2002: a. on an ongoing basis and from an accounting perspective under US Financial Accounting Standard Statement 132, the Marconi Plan had assets with a value of US$164,915,249 and was underfunded by US$18,378,172; and b. on an ongoing basis and from an accounting perspective under US Financial Accounting Standard Statement 132, the RELTEC Plan had assets with a value of US$47,345,086 and was underfunded by US$15,812,831. This estimate is based on valuations prepared for the relevant plans as at 31 December 2001, adjusted for turnover in the first quarter of 2002 and a change in the discount rate from 7 1/4 per cent. to 6 1/2 per cent. and rolled forward to 30 September 2002. An actuarial report for the plans' status, as at 31 December 2002, is not expected to be completed for several months. Potential consequences of the underfunding of the US plans on Corp and plc If a sale of any of the US businesses which sponsor or participate in either of the defined benefit pension plans (or any subsidiary or division of those businesses) occurs, the portion of the assets and liabilities under any such plan pertaining to the employees (and, perhaps, retirees) of the entities being sold could either be transferred to the buyer's defined benefit plan or retained in the Marconi Plan or the RELTEC Plan, as applicable. If, at the time that assets and liabilities are to be transferred from the Marconi Plan or the RELTEC Plan, either of such plans were underfunded, the assets and liabilities transferred might have to be determined based on assumptions prescribed by the United States Pension Benefit Guaranty Corporation ("PBGC"). The PBGC is a US government agency established under ERISA to assure the payment of certain guaranteed levels of benefits under most defined benefit plans. When liabilities are determined on the basis of the fairly conservative PBGC assumptions they generally result in a greater liability than the liability as determined under applicable accounting standards for an ongoing plan or an amount an insurance company would charge to assume the liability. The PBGC has an early warning programme under which it scrutinises the financial soundness of the parties to a corporate transaction and the funding status of the relevant tax-qualified defined benefit pension plans. The PBGC has the authority under ERISA to terminate an underfunded plan, thereby triggering the required payment by the plan sponsor of any funding shortfall, if the PBGC determines that the proposed transaction could reasonably be expected to increase unreasonably its risk of possible long-term loss if the plan is not terminated. If a sale of a US business were to occur at a time when the Marconi Plan or the RELTEC Plan is underfunded, PBGC involvement is possible, depending upon the circumstances then surrounding such potential sale. If the PBGC were to elect to become involved, such involvement could impede or delay any such proposed transaction, increase its cost or reduce the net sale proceeds depending upon what, if any, action might be required by the PBGC. The PBGC would also have the power to bring an action to terminate the Marconi Plan or the RELTEC Plan if, at any time, the participating employers were unable to contribute the annual amount required to satisfy minimum funding obligations under US law, the plans were unable to pay benefits when due, or certain so-called reportable events were to occur, and, in each case, the PBGC were to determine that its risk of possible long-term loss could reasonably be expected to increase unreasonably. The filing of this document with the Court constituted a reportable event and Corp and plc have notified the PBGC accordingly. In order to substantially reduce the uncertainty of the potential involvement of the PBGC, Corp and plc have entered into a legally binding memorandum of understanding with the PBGC under which the PBGC has agreed not to terminate the Marconi Plan or the RELTEC Plan solely as a result of the Restructuring nor make a claim under the plc Scheme, in exchange for which Corp has agreed to provide (i) certain guarantees to the PBGC relating to potential liabilities of its United States subsidiaries under the two plans, (ii) if Corp intends to sell any of its business units in the United States to a third-party purchaser whose debt immediately following the consummation of such transaction is not then rated investment grade, no proposed transfer of assets and liabilities of the Marconi Plan or the RELTEC Plan to a pension plan of the third-party purchaser will be made without the consent of the PBGC, (iii) a commitment to fund, from the proceeds of sale, any shortfall in the 132

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- Marconi Plan or RELTEC Plan, as applicable, which is attributable to any United States business unit being sold, with the amount to be funded based on then applicable PBGC safe harbour assumptions used for plan termination purposes, and (iv) accelerated funding of contributions beyond the minimum otherwise legally required. See Appendix 19 for a more detailed discussion of the memorandum of understanding with the PBGC. D.12 LISTING AND DEALING Application has been made to the UKLA for the New Shares, the New Notes and the Warrants to be admitted to the Official List of the UKLA and to the London Stock Exchange for the New Shares, the New Notes and the Warrants to be admitted to trading on the London Stock Exchange's market for listed securities. It is expected that Listing will become effective and dealings in the New Shares, the New Notes and the Warrants will commence at 8.00 a.m. (London time) on the Effective Date which is currently expected to be 19 May 2003, but the Corp Scheme is not conditional on Listing becoming effective and the New Shares, the New Notes and the Warrants may therefore be issued as unlisted securities. Corp will use its reasonable endeavours to effect the Listing of the New Shares, the New Notes and the Warrants as soon as possible on or after the Effective Date of the Corp Scheme. A document comprising a prospectus relating to Corp has been prepared in accordance with the Listing Rules made under section 74 of the FSMA and a copy of it will be delivered for registration to the Registrar of Companies in England and Wales pursuant to section 83 of the FSMA. Corp will apply to list the ADRs in respect of its shares on NASDAQ and will use its reasonable endeavours to effect this NASDAQ listing as soon as practicable following the Effective Date of the Corp Scheme. It is currently expected that the NASDAQ listing will become effective during the third calendar quarter of 2003. Please see Part F.2 of this Section: Risk factors for a discussion of certain risks relating to delay and potential delay in the listing of the New Shares, New Notes, Warrants and ADRs. D.13 REPORTING REQUIREMENTS AND ENTITLEMENT TO INFORMATION Corp files reports and other information with the SEC under the US Securities Exchange Act of 1934, as amended. Reports and other information filed with, or submitted to, the SEC by Corp can be inspected and copied at the public reference facilities maintained by the SEC at 450 Fifth Street, N.W., Room 1024, Washington D.C. 20549 and at the SEC's regional offices at Citicorp Center, 500 West Madison Street, Suite 1400, Chicago, Illinois 60661. Reports and other information are also available to the public through the internet in the EDGAR database on the SEC's Web site at http://www.sec.gov. Pursuant to the terms of the indentures governing the New Notes, following the Restructuring Corp will begin to file annual, quarterly and periodic reports with the SEC on Form 10-K, Form 10-Q and Form 8-K, respectively, as if it were a US domestic issuer, subject to certain specified exceptions (as more particularly described in Appendix 8, under the caption "SEC Reports; Other Information"). (Corp will remain a foreign private issuer and as such will not be subject to and (except as described herein) does not intend to comply with US proxy rules or any other provision of the US securities laws from which foreign private issuers are exempted.) The first such filing will be a Form 10-Q quarterly report in respect of the quarter ending 30 September 2003. Prior to that time, Corp will file an annual report on Form 20-F for the year ending 31 March 2003 within 90 days of the financial year end, and will submit a quarterly report in respect of the quarter ending 30 June 2003 under cover of Form 6-K within 60 days of the quarter end, in each case including financial statements in accordance with or reconciled to US GAAP and non-financial statement disclosures otherwise as required by Form 10-K or Form 10-Q, as the case may be, subject to certain specified exceptions (as more particularly described in Appendix 8, under the caption "SEC Reports; Other Information"). All of the above reports (regardless of the forms under which they are filed or submitted) will also include the certifications required with respect to filings by US domestic issuers on Form 10-K and Form 10-Q pursuant to the Sarbanes-Oxley Act of 2002 and SEC rules adopted thereunder. In addition, Corp will hold quarterly investor conference calls following the release of such reports. The specific reporting requirements described above will cease to apply once the New Notes are no longer outstanding. At any time thereafter, subject to the requirements of applicable law and regulation, Corp will be 133

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- free to discontinue filing SEC reports on the forms used by US domestic issuers, as well as the other reporting practices described in the previous paragraph. D.14 MEMORANDUM AND ARTICLES A summary of certain provisions of the Memorandum of Corp which has been amended, and the Articles of Corp which have been adopted, in each case conditionally on the allotment of the New Shares pursuant to the Corp Scheme, is in Appendix 14. D.15 AMERICAN DEPOSITARY RECEIPTS GENERAL Corp will establish an ADR programme in respect of the New Shares. Elections may be made in Claim Forms and Account Holder Letters to have all or any portion of the New Shares deliverable pursuant to the Schemes delivered in the form of ADRs. Any person who elects to receive New Shares in the form of ADRs also will receive all future distributions of New Shares to which such person may be entitled pursuant to the Schemes in the form of ADRs. As described below no depositary fees will be payable at any time in connection with the initial issuance of ADRs pursuant to the Schemes and any UK stamp duty or SDRT payable in this respect will be met by Corp. ADRs will be issued pursuant to the Schemes in reliance on the exemption from Securities Act registration provided by Section 3(a)(10) thereof (or, in the case of plc Shareholders, in transactions not subject to such registration). Following their initial issuance, such ADRs may be sold in ordinary secondary market transactions without restriction under the Securities Act (subject to the restrictions applicable to "affiliates" described in Part D.16 of this Section). In addition, a registration statement on Form F-6 will be filed with the SEC in relation to the ADRs. It is currently expected that this registration statement will be effective prior to the Effective Date of the Corp Scheme. Once this registration statement is effective, outstanding Corp Shares may be deposited into the ADR programme in exchange for ADRs. Such ADRs may then be sold in ordinary secondary market transactions without restriction under the Securities Act. Corp will apply to list the ADRs on NASDAQ and will use its reasonable endeavours to effect this NASDAQ listing as soon as practicable following the Effective Date of the Corp Scheme. It is currently expected that the NASDAQ listing will become effective during the third calendar quarter of 2003. Persons who are considering making an election to receive New Shares in the form of ADRs should note that, unless and until the NASDAQ listing becomes effective, development of a liquid trading market for the ADRs will be inhibited, which is likely to have a material adverse effect on their value. A summary of the material terms of the ADRs is set out in Appendix 16. RESPONSIBILITY FOR FEES AND TAXES IN CONNECTION WITH ADRS Persons electing to receive ADRs pursuant to the Schemes Scheme Creditors and Designated Recipients who receive New Shares in the form of ADRs pursuant to the Schemes at any time will not be responsible for any fees or expenses of The Bank of New York, as ADR depositary, or any UK stamp duty or SDRT, in respect of the initial issuance of such ADRs. The Bank of New York has agreed to waive its fees and expenses in this connection, and any such UK stamp duty or SDRT will be met by Corp. Such persons will, however, be responsible for any other taxes or charges arising in connection with such initial issuance of ADRs, as well as any fees, expenses, taxes or charges arising in connection with any subsequent transaction involving ADRs (except to the extent described below under "General fee holiday"). Persons electing to receive New Shares pursuant to the Schemes Subject to compliance with the procedures referred to below, Scheme Creditors and Designated Recipients who receive New Shares pursuant to the Schemes will not be responsible for any fees or expenses of The Bank of 134

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- New York in respect of the initial issuance of ADRs upon deposit of those New Shares (or an equivalent number of Corp Shares) in exchange for ADRs, if such deposit is effected prior to the earlier of (x) the date falling two months after the effectiveness of the NASDAQ listing of the ADRs and (y) 30 September 2003. The Bank of New York has agreed to waive its fees and expenses in this connection. In addition, subject to compliance with the procedures referred to below, Scheme Creditors and Designated Recipients who receive New Shares pursuant to the Schemes will not be responsible for any UK stamp duty or SDRT arising in connection with the initial issuance of ADRs upon deposit of those New Shares (or an equivalent number of Corp Shares) in exchange for ADRs, if such deposit is effected prior to the date falling two months after the effectiveness of the NASDAQ listing of the ADRs. Any such UK stamp duty or SDRT will be met by Corp. To qualify for the treatment described above, Scheme Creditors and Designated Recipients must comply with certain procedures, including providing such certifications or other evidence as Corp and The Bank of New York may reasonably require in order to permit verification of the number of New Shares obtained by the depositor pursuant to the Schemes. For information with respect to the relevant procedures, Scheme Creditors and Designated Recipients should contact The Bank of New York's office in London on (attention Mr Peter Ridgwell), telephone +44 207 964 6168, facsimile +44 207 964 6043. Except insofar as these arrangements apply, Scheme Creditors and Designated Recipients will be responsible for all taxes or charges arising in connection with the initial issuance of ADRs as described above, as well as any fees, expenses, taxes or charges arising in connection with any subsequent issuance of or other transaction involving ADRs (except to the extent described below under "General fee holiday"). GENERAL FEE HOLIDAY The Bank of New York has agreed to waive any payment in respect of its fees and expenses that would otherwise be required under the Deposit Agreement in connection with any deposit of Corp Shares in exchange for ADRs that is effected prior to the date falling two months after the Effective Date of the Corp Scheme. This "fee holiday" will be implemented without regard to the special arrangements for Scheme Creditors and Designated Recipients described above. Persons depositing Corp Shares during this period (other than Scheme Creditors and Designated Recipients, to the extent described above) will, however, be responsible for any taxes or other charges (including UK stamp duty or SDRT) arising in connection with the issuance of ADRs. D.16 US SECURITIES LAW CONSIDERATIONS CONSIDERATIONS FOR SCHEME CREDITORS AND BONDHOLDERS US federal securities laws The New Shares, ADRs and New Notes issued to Scheme Creditors and Bondholders pursuant to the Schemes will not be registered under the Securities Act in reliance on the exemption from registration provided by Section 3(a)(10) thereof, and will not be registered under the securities laws of any state of the US in reliance on exemptions provided under the securities laws of each state of the US in which Scheme Creditors and Bondholders are located. The issue of New Shares, ADRs and New Notes to Scheme Creditors and Bondholders located in the states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont will, however, be subject to the limitations described in "US state securities laws" below. Any Scheme Creditor or Bondholder that is not an affiliate, for purposes of the Securities Act, of Corp or plc prior to the implementation of the Schemes and is not an affiliate of Corp following implementation of the Schemes may sell New Shares, ADRs and New Notes received pursuant to the Schemes in ordinary secondary market transactions without restriction under the Securities Act. Any Scheme Creditor or Bondholder that is an affiliate of Corp or plc prior to the implementation of the Schemes and/or is or becomes an affiliate of Corp following implementation of the Schemes will be subject to restrictions on the sale of New Shares, ADRs and New Notes received pursuant to the Schemes pursuant to Rule 145(d) under the Securities Act. 135

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- For purposes of the Securities Act, an "affiliate" of any person is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, that person. Scheme Creditors and Bondholders that believe they are or may be "affiliates" of Corp or plc for purposes of the Securities Act should consult their own legal advisers prior to any sale of New Shares, ADRs or New Notes received pursuant to the Schemes. US state securities laws Corp and plc have formed the view, based on the advice of US state securities law counsel, that the distributions of New Shares, ADRs and New Notes to Scheme Creditors and Bondholders in the United States would be prohibited except after compliance with unduly onerous conditions unless made pursuant to available exemptions from state securities registration requirements under applicable state law. Other than in the states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont, exemptions are available without regard to the identity or status of the persons to whom securities are issuable under the Schemes. In these seven states the scope of the available exemptions will not permit New Shares, ADRs and New Notes to be issued through the Schemes under all circumstances. Accordingly Scheme Creditors and Bondholders in Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont will be eligible to receive New Shares, ADRs and New Notes pursuant to the Schemes only if they fall into one of the categories of persons described below, such that an applicable state-law exemption will be available. Bondholders in Colorado, Connecticut, Illinois and Vermont should note that they will be eligible to receive securities pursuant to the Corp Scheme under state-law exemptions applicable to transactions by an issuer with its existing security holders. The Claim Form will require each person who completes it (other than the Trustees), and the Account Holder Letter will require Account Holders, to confirm certain facts in connection with the US state securities law restrictions referred to above. To the extent that any person located in one of these states is not eligible to receive securities pursuant to the Schemes by virtue of these securities law restrictions, such person will receive cash instead. These matters are discussed in further detail in Part C.9 of this Section. SCHEME CREDITORS AND BONDHOLDERS IN ARIZONA, CALIFORNIA, COLORADO, CONNECTICUT, ILLINOIS, OHIO AND VERMONT SHOULD CAREFULLY CONSIDER THE ELIGIBILITY CRITERIA DESCRIBED BELOW, THE PROVISIONS OF THE SCHEMES WITH RESPECT TO LEGAL AND REGULATORY RESTRICTIONS GENERALLY AND THE CONTENTS OF THE CONFIRMATIONS TO BE INCLUDED IN THE CLAIM FORM AND ACCOUNT HOLDER LETTER AS DESCRIBED IN PART C.9 OF THIS SECTION. ANY SUCH PERSONS WHO ARE IN DOUBT AS TO HOW THESE RESTRICTIONS MAY AFFECT THEM ARE STRONGLY ADVISED TO CONSULT THEIR PROFESSIONAL ADVISERS. For these purposes, a Scheme Creditor or Bondholder will be deemed to be located in a state if such Scheme Creditor or Bondholder (or, in the case of a legal entity, the person acting on behalf of such Scheme Creditor or Bondholder) is physically present within that state at the time that (i) such person receives the Scheme Document, or any portion thereof or any information with respect thereto which results in a Claim Form or Account Holder Letter (as the case may be) being submitted by or on behalf of such person, or (ii) such person submits a Claim Form or transmits instructions with respect to submission of an Account Holder Letter (as the case may be). The categories of Scheme Creditors and Bondholders located in the states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont to or to the order of whom New Shares, ADRs and New Notes will be distributed through the Schemes are as follows: Arizona -- any bank, savings institution, trust company, insurance company, investment company as defined in the US Investment Company Act of 1940, a pension or profit sharing trust or other financial institution or institutional buyer, or a dealer, whether the person is acting for itself or in a fiduciary capacity. California -- any broker-dealer, bank, savings and loan association, trust company, insurance company, investment company registered under the US Investment Company Act of 1940, or pension or profit-sharing trust (other than a pension or profit-sharing trust of the issuer, a self-employed individual retirement plan or an individual retirement account); any organisation described in Section 501(c)(3) of the US Internal Revenue Code, as amended to 29 December 1981, which has total assets (including endowment, annuity and life income funds) 136

D.17 SECURITIES LAW RESTRICTIONS IN FRANCE, ITALY AND MALAYSIA This Part D.17 sets out information regarding securities law restrictions on the distribution of New Shares, New Notes and Warrants pursuant to the Schemes under the laws of France, Italy and Malaysia to persons located in those jurisdictions. FRANCE Corp and plc have formed the view, based on the advice of French legal counsel, that the distributions of New Shares and New Notes to Scheme Creditors, Bondholders and Designated Recipients in France would be prohibited except after compliance with unduly onerous conditions, unless made pursuant to an exemption from the provisions of French law relating to public offerings. Accordingly, New Shares and New Notes will be distributed pursuant to the Schemes to Scheme Creditors, Bondholders and Designated Recipients in France only in reliance on the exemption provided under Article L.411-2 of the French Monetary and Financial Code and Decree no. 98-880 dated 1 October 1998 to persons that are "qualified investors" as defined under such Article. The Claim Form will require each person who completes it (other than the Trustees), and the Account Holder Letter will require Account Holders, to confirm certain facts in connection with the French legal restrictions described above. To the extent that any person located in France is not eligible to receive securities pursuant to the Schemes by virtue of these restrictions, such person will receive cash instead. These matters are discussed in further detail in Part C.9 of this Section. For these purposes, a person will be deemed to be located in France if this Scheme Document, or notice that this Scheme Document is available, (i) is sent to him at an address (including the registered address for a company and the branch address for a branch) in the Republic of France, or (ii) is made available to him by electronic means and such person (if a natural person) is a French national or (if a legal person) has its registered address in the Republic of France. SCHEME CREDITORS, BONDHOLDERS AND DESIGNATED RECIPIENTS LOCATED IN FRANCE SHOULD CAREFULLY CONSIDER THE ELIGIBILITY CRITERIA DESCRIBED ABOVE, THE PROVISIONS OF THE SCHEMES WITH RESPECT TO LEGAL AND REGULATORY RESTRICTIONS GENERALLY AND THE CONTENTS OF THE CONFIRMATIONS TO BE INCLUDED IN THE CLAIM FORM AND ACCOUNT HOLDER LETTER AS DESCRIBED IN PART C.9 OF THIS SECTION. ANY SUCH PERSONS WHO ARE IN DOUBT AS TO HOW THESE RESTRICTIONS MAY AFFECT THEM ARE STRONGLY ADVISED TO CONSULT THEIR PROFESSIONAL ADVISERS. Corp has formed the view, on the advice of French counsel, that the distribution of New Shares and Warrants pursuant to the Corp Scheme to plc Shareholders in France is not currently prohibited by French law or regulation. ITALY The distributions of the New Shares, New Notes and Warrants have not been approved by the Italian Securities Exchange Commission ("CONSOB") pursuant to Italian securities legislation. A formal request has been submitted to CONSOB seeking confirmation that the distributions of the securities under the Schemes do not constitute public offerings under such legislation. However, as of the date of this document, no such confirmation has yet been received. If CONSOB does not provide the requested confirmation, Corp and plc have formed the view, based on the advice of Italian legal counsel, that the distributions of New Shares and New Notes to Scheme Creditors and Bondholders, and of Warrants to plc Shareholders, in Italy would be prohibited except after compliance with unduly onerous conditions, unless made pursuant to an exemption from the provisions of Italian law relating to 139

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- public offerings. The following exemptions under Italian law are potentially applicable in connection with the various distributions to be made pursuant to the Schemes: - Corp Scheme -- Scheme Creditors: Except as described in the next paragraph, a Corp Scheme Creditor in Italy will be eligible to receive New Shares and New Notes pursuant to the Corp Scheme if (i) such person is a "professional investor" as defined in the Consolidated Financial Act Article 30, paragraph II and in CONSOB Regulation 11522/1998 Article 31, paragraph II or (ii) the number of all such persons that are not "professional investors" does not exceed 200; - Corp Scheme -- Bondholders: Bondholders in Italy will be eligible to receive New Shares and New Notes pursuant to the Corp Scheme only if the number of such persons does not exceed 200; - plc Scheme -- Scheme Creditors and Bondholders: plc Scheme Creditors and Bondholders in Italy will be eligible to receive New Shares and New Notes pursuant to the plc Scheme if (i) such persons are "professional investors" as defined in the Consolidated Financial Act Article 30, paragraph II and in CONSOB Regulation 11522/1998 Article 31, paragraph II or (ii) the number of all such persons that are not "professional investors" does not exceed 200; - Corp Scheme -- plc Shareholders: plc Shareholders in Italy will be eligible to receive Warrants pursuant to the Corp Scheme only if the number of such persons does not exceed 200. Based on the advice of Italian legal counsel and such information as is available to it, (i) Corp currently believes that the exemption with respect to distributions of securities to limited numbers of persons will not be available in connection with distributions in respect of claims by Bondholders located in Italy under the Corp Scheme, and (ii) Corp and plc, respectively, believe that there is significant doubt as to the availability of this exemption in connection with other distributions to Scheme Creditors under the Corp Scheme and in connection with distributions under the plc Scheme. The determination as to whether securities can be distributed in reliance on this exemption will be made by Corp or plc (as the case may be) in its sole discretion following the Effective Date of the relevant Scheme based on the advice of Italian legal counsel and such information as is available to it. The Claim Form will require each person who completes it (other than the Trustees), and the Account Holder Letter will require Account Holders, to confirm certain facts in connection with the Italian legal restrictions described above. To the extent that any person in Italy is not eligible to receive securities pursuant to the Schemes by virtue of these restrictions, such person will receive cash instead. These matters are discussed in further detail in Part C.9 of this Section. For these purposes, a person will be deemed to be located in Italy if such person (i) is a natural person and is resident or domiciled within the geographical territory of Italy or (ii) is a legal person and has its registered office (sede legale) within the geographical territory of Italy or (iii) is a legal person having any other office or conducting any business or other activities within the geographical territory of Italy as a result of which it is or is required to be registered in Italy. SCHEME CREDITORS, BONDHOLDERS AND PLC SHAREHOLDERS IN ITALY SHOULD CAREFULLY CONSIDER THE ELIGIBILITY CRITERIA DESCRIBED ABOVE, THE PROVISIONS OF THE SCHEMES WITH RESPECT TO LEGAL AND REGULATORY RESTRICTIONS GENERALLY AND THE CONTENTS OF THE CONFIRMATIONS TO BE INCLUDED IN THE CLAIM FORM AND ACCOUNT HOLDER LETTER AS DESCRIBED IN PART C.9 OF THIS SECTION. ANY SUCH PERSONS WHO ARE IN DOUBT AS TO HOW THESE RESTRICTIONS MAY AFFECT THEM ARE STRONGLY ADVISED TO CONSULT THEIR PROFESSIONAL ADVISERS. Persons in Italy should note that New Shares, New Notes or Warrants received pursuant to an exemption may not be offered, sold or delivered nor may copies of this document or any other document relating to the New Shares, New Notes or Warrants be distributed in Italy except (i) pursuant to the exemptions under Legislative Decree No. 58 of 24 February 1998 and its implementing CONSOB Regulations, or (ii) to an Italian resident who submits an unsolicited offer to purchase such New Shares, New Notes or Warrants. Corp has formed the view, on the advice of Italian legal counsel, that the distribution of New Shares pursuant to the Corp Scheme to plc Shareholders in Italy is not currently prohibited by Italian law or regulation. 140

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- MALAYSIA Corp and plc have formed the view, on the advice of Malaysian legal counsel, that the issue and allotment of New Shares, New Notes or Warrants to Scheme Creditors, Bondholders, Designated Recipients or plc Shareholders located in Malaysia would be prohibited except after compliance with unduly onerous conditions. The Claim Form will require each person who completes it (other than the Trustees), and the Account Holder Letter will require Account Holders, to confirm certain facts in connection with these Malaysian legal and regulatory restrictions. Any person located in Malaysia will not be eligible to receive securities pursuant to the Schemes and will receive cash instead, as described in Part C.9 of this Section. For these purposes, a person will be deemed to be located in Malaysia if such person (i) is a natural person and is resident in Malaysia, or (ii) is a legal person and has its principal place of business in Malaysia, or (iii) is deemed to be resident in Malaysia for tax purposes pursuant to the Malaysian Income Tax Act 1967 or any other Malaysian tax legislation. SCHEME CREDITORS, BONDHOLDERS, DESIGNATED RECIPIENTS AND PLC SHAREHOLDERS LOCATED IN MALAYSIA SHOULD NOTE THAT THEY WILL RECEIVE CASH IN LIEU OF ANY SECURITIES TO WHICH THEY WOULD OTHERWISE BE ENTITLED UNDER THE SCHEMES, AND SHOULD CAREFULLY CONSIDER THE RELEVANT PROVISIONS OF THE SCHEMES AS DESCRIBED IN PART C.9 OF THIS SECTION.

The plc Scheme provides that plc will set aside the sum of L7,000,000 from the cash element of the Corp Scheme Consideration received via Ancrane which, together with plc's cash of approximately L2,300,000, interest on the aggregate of these two cash amounts and L2,000,000 available to be drawn (at Corp's request) under a letter of credit to be provided in favour of the plc Scheme Supervisors by HSBC Bank plc, will be available to meet plc's Ongoing Costs.

USA </Table> D.25 CORP GROUP INDEBTEDNESS STATEMENT At the close of business on 21 February 2003, the total indebtedness of the Corp Group was as follows: <Table> <Caption> L million --------- <S> <C> Secured loans 17 Unsecured loans 4,578 Unsecured overdrafts 1 Finance lease obligations 6 --------- 4,602 ========= </Table> Included within the indebtedness listed in the table above is L4,181 million that is guaranteed by plc. In addition, included within unsecured loans is L263 million relating to loan creditor balances with plc and fellow subsidiaries of plc outside the Corp Group. Save as disclosed above, and apart from intra-group liabilities and guarantees, the Corp Group did not have outstanding as at 21 February 2003 any material loan capital (whether issued or created but unissued), term loans, other borrowings or indebtedness in the nature of borrowing (including bank overdrafts and liabilities under acceptances (other than normal trade bills) or acceptance credits, mortgages, charges, hire purchase commitments and obligations under finance leases) or material guarantees. At 21 February 2003 the Corp Group had contingent liabilities in total of L30 million. In the opinion of Corp, these contingent liabilities are not expected to have a material adverse effect on the Corp Group. The Corp Group is engaged in a number of legal proceedings relating, amongst other things, to class shareholder actions and claims relating to contracts, industrial injury and patent infringement. The Corp Group is defending these claims, the estimated possible unprovided exposure of which is included in the contingent liabilities total disclosed above, and Corp currently believes that the claims are unlikely to be settled for amounts resulting in material cash or other asset outflows. 150

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- At the close of business on 21 February 2003, the Corp Group had the following cash balances: <Table> <Caption> L million --------- <S> <C> Secured 763 Collateral against bonding facilities 122 Held by captive insurance company 17 --------- Restricted cash 902 Other 181 --------- Total cash at bank and in hand 1,083 ========= </Table> Of the secured cash, L720 million relates to amounts held under an interim security by the Group's Syndicate Banks and Bondholders and also by Barclays Bank PLC (in its capacity as an ESOP Derivative Bank) granted on 13 September 2002. A further L27 million relates to cash deposited against ESOP Derivative Banks for the Strategic Communications business and L16 million relates to cash deposited against secured loans in Italy. For the purposes of the above, amounts denominated in currencies other than sterling have been translated into sterling at the exchange rates prevailing at the close of business on 21 February 2003. D.26 NO SIGNIFICANT CHANGE Save for the operating results for the three months ended 31 December 2002 disclosed in Part A of Appendix 4, there has been no significant change in the financial or trading position of the Corp Group or the plc Group since 30 September 2002, the date to which the last audited consolidated accounts of the Corp Group and the plc Group were prepared as set out in Appendix 1 and Appendix 3 respectively. D.27 CORP INCORPORATION AND REGISTERED OFFICE Corp was incorporated under the name The General Electric Company (1900) Limited on 27 September 1900 under the Companies Acts 1862 to 1898 as a private limited company limited by shares and registered in London, England with number 67307. On 24 August 1903, The General Electric Company (1900) Limited changed its name to The General Electric Company, Limited, on 29 November 1968 to The General Electric and English Electric Companies Limited and on 17 September 1970 to The General Electric Company Limited. On 4 January 1982, The General Electric Company Limited was re-registered as a public limited company under the Companies Acts 1948 to 1980 and became The General Electric Company, p.l.c. On 7 March 2000, The General Electric Company, p.l.c. changed its name to Marconi Corporation plc. The registered office of Corp and plc is at New Century Park, P.O. Box 53, Coventry, Warwickshire, CV3 1HJ. Corp and plc have a head office at Regent's Place, 338 Euston Road, London, NW1 3BT. D.28 CORP SHARE CAPITAL Information as to the authorised, issued and fully paid share capital of Corp is set out in Appendix 13. D.29 MATERIAL SHAREHOLDINGS IN CORP Immediately following the Effective Date of the Corp Scheme the name of each person (other than the Escrow Trustee and its nominee) who, directly or indirectly, is expected to be interested in 3 per cent. or more of Corp's ordinary share capital, and the amount of such person's interest is expected to be as set out below. The Escrow Trustee's nominee is expected to hold up to 14 per cent. of the New Shares in issue immediately after the Effective Date, such shares being held on trust for Scheme Creditors as provided in the Schemes and the Escrow and Distribution Agreement. The Escrow Trustee's nominee has instructions not to exercise any voting rights conferred by those shares. These interests have been calculated by Corp based solely on the information concerning Scheme Creditors (other than the Trustees and disputed creditors) with Known Claims set out in Schedule 3 to each of the Schemes. 151

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- <Table> <Caption> Percentage of ordinary Name No. of Corp Shares share capital of Corp ---- ------------------ ---------------------- <S> <C> <C> Appaloosa Investment Ltd Partnership 48,717,593 4.87% Cerebrus Partners LP New York 34,058,285 3.41% Chase Manhattan Bank 33,843,309 3.38% </Table> Neither Corp nor plc makes any representation as to whether or not any of the above persons will retain, or whether any such person or any other person will have acquired, an interest in any Known Claim at the Effective Date, whether any such Known Claim will be Admitted in whole or part under the relevant Scheme or whether any New Shares which any such person may receive under the Schemes will be retained by such person after the Effective Date. Accordingly the above calculation should not be relied upon as an accurate indication of the likely material shareholdings in Corp on or after the Effective Date. The holdings of Bonds by Bondholders (and therefore their prospective holdings of New Shares) cannot be determined on the basis of the Known Claims set out in Schedule 3 to each of the Schemes. Save as disclosed in this Part D.29, Corp is not aware of any interest which will represent 3 per cent. or more of the issued ordinary share capital of Corp following the Effective Date of the Corp Scheme. So far as Corp is aware, no person or persons, directly or indirectly, jointly or severally exercise or could exercise control over Corp. D.30 TAX A description of certain UK and US tax consequences for Scheme Creditors and Bondholders of implementation of the Schemes and of holding the Scheme Consideration is set out in Appendix 17. Scheme Creditors and Bondholders in jurisdictions other than the UK and the US are strongly urged to consult their own professional advisers to determine their own tax position. D.31 INSURANCE The Group maintains the types of property and liability insurance which Corp and plc regard as appropriate given the nature of the risks run in the course of its business, and for amounts which they consider adequate. When considering the appropriateness of insurance cover, the Group has made detailed assessments of insurable risks using both in-house professionals and the advice of insurance brokers. The Group has determined what it believes to be the appropriate level of cover having regard, among other things, to the Group's loss record, the industry in which it operates, its risk tolerance level, the cost of cover relative to the risk, customer and legal requirements and any relevant and available information on the levels of cover typically purchased by other comparable companies which operate in the Group's industry. D.32 ENVIRONMENTAL AND OTHER REGULATIONS ENVIRONMENTAL AND EMPLOYEE HEALTH AND SAFETY MATTERS The Group is subject to increasingly stringent regulation under various UK, US, EU and other international, national and local laws and regulations relating to employee safety and health, and environmental protection, including law and regulations governing air emissions, water discharges and the use, management and disposal of hazardous substances. One of the many environmental laws affecting the Group in the US is the Comprehensive, Environmental Response, Compensation, and Liability Act, which is the primary federal statute governing clean-up of contaminated properties. CERCLA can impose joint, several and retroactive liability for the costs of investigating and cleaning up contaminated properties, without regard to fault or the legality of the original conduct. Potentially liable parties under CERCLA can include current and former owners or operators of a site, as well as those who generate or arrange for the disposal of hazardous substances. Environmental laws in other jurisdictions can also impose significant clean-up liabilities. 152

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART D -------------------------------------------------------------------------------- The Group is currently conducting investigation and clean-up at approximately 20 contaminated sites, principally in the US including four clean ups pursuant to obligations imposed under CERCLA. The remaining sites are being cleaned up voluntarily in connection with a prior property sale or purchase, or pursuant to government directive. The Group estimates the total cost to clean up all of these sites will be between approximately L10 million and L20 million. A number of these and other current and former Group sites were associated with hazardous substance use and may give rise to unforeseen liabilities. The Group could therefore incur additional clean-up costs upon the discovery of new contamination at these or other sites for which the Group may be found to be responsible, either directly under CERCLA or other laws, or through a contractual indemnity obligation as the result of a prior property or business sale. The Group also could incur additional costs as a result of any related personal injury or property damage claims. Although such additional costs, if any, could be substantial, the Group is not aware of any material claims and does not expect future clean-up or related costs to materially affect the Group. See Appendix 20 for a description of a toxic tort claim against Plessey Precision Metals. This claim is in its early stages and no estimate of liability can be formed at this point. Litigation is by its nature an unpredictable form of risk and is disclosed wherever unliquidated damages are sought but no information currently available to the Group indicates a material liability of Plessey Precision Metals in this matter. The European Commission has issued two directives which will require member states of the EU to meet certain targets for collection, re-use and recovery of waste electrical and electronic equipment. It is likely that these obligations will be achieved through legislation placing the responsibility for meeting these obligations on equipment producers. Producers will also be required to phase out certain hazardous materials from the equipment. This legislation could significantly increase costs to producers of electrical and electronic equipment. The Group regularly audits its facilities' compliance with employee safety and environmental requirements. The Group has not incurred material capital expenditures for environmental, health or safety matters during the past three financial years, nor does the Group anticipate having to incur material capital expenditures during the current or the succeeding financial years. Although environmental costs cannot be predicted with certainty, the Group believes that costs relating to non-compliance or liability under current environmental, health and safety laws and regulations will not have a material adverse effect on the Group's financial condition or results of operations as a whole. OTHER GOVERNMENT REGULATION The Group's products are subject to industry-specific government regulation and legislation in the United States, the EU and throughout the world. For example, the Group's Network Equipment business must comply with US Federal Communications Commission requirements and regulations and other safety regulations governing communications products sold in the United States. The Group's businesses would suffer if they failed to obtain or lost the certifications, clearances and authorisations required to participate in new or existing projects. Further, the Group could be subject to fines, criminal sanctions or the revocation of important licences and certifications if it fails to comply with government regulations. The Group believes that any non-compliance or liability under current government regulations will not have a material adverse effect on the Group's financial condition or results of operation as a whole. D.33 NO WAIVER OF DIVIDENDS There are no arrangements in existence under which future dividends of Corp are to be waived or agreed to be waived. 153

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- E. MATERIAL INTERESTS OF DIRECTORS AND TRUSTEES E.1 DIRECTORS The identities of the directors of Corp and plc are set out in Part A.10 of this Section. None of the directors of Corp and plc has any material interest (whether as director, member, optionholder, creditor or otherwise) in the proposed Restructuring except as disclosed below. Save as disclosed in this Part E.1 the effect of the proposed Restructuring on interests of directors of Corp and plc will not be different from the effect on similar interests of other persons. DIRECTORS' SERVICE AGREEMENTS AND EMOLUMENTS The executive directors' contracts are with Corp. New forms of service agreement have been executed between Corp and each of Michael Parton and Michael Donovan, to be effective on the Effective Date. The summary below refers to the agreements (a) as they currently stand and (b) as they will be on and after the Effective Date. a. Directors' current service agreements and emoluments The following executive directors currently have service agreements with Corp as follows: MICHAEL PARTON, as Chief Executive Officer, has a service agreement dated 2 May 2002 with plc, which was novated to Corp on 10 January 2003. The agreement lasts until Mr Parton's sixty-second birthday but may be terminated earlier by either party giving to the other twelve months' notice. The basic salary is L525,000 per annum, which is reviewable on 1 July 2003 (and thereafter annually) and Mr Parton is eligible to participate in such incentive and stock option plans as are generally offered to employees of Mr Parton's status. His agreement provides for participation in a company car scheme and private medical healthcare for himself and his family. Mr Parton is entitled to participate in UK Plan (described in Part D.11 of this Section) to which he contributes 3 per cent. of his basic salary (up to a maximum of 15 per cent. of the Inland Revenue earnings cap, which is L97,200 in the 2002/2003 tax year). As a consequence of the earnings cap restricting the amount an employer can contribute into an exempt approved pension plan, Mr Parton has a funded unapproved retirement benefits scheme (a "FURBS"), to which Corp contributes an amount equal to 21 per cent. of his basic salary (with a further 14 per cent. of his basic salary being paid to Mr Parton). In addition, and as compensation for Mr Parton changing a defined benefit pension arrangement into a defined contribution plan in 2002, Corp has agreed to make net contributions of L88,250 to the FURBS and associated non-pensionable allowances of L58,833.33 to Mr Parton himself on 15 April 2003, 15 July 2003, 15 October 2003 and 15 January 2004. The payments are conditional on Mr Parton remaining in employment with Corp and if his employment is terminated (other than for cause), any payments which have not been made on or before the termination date will become due immediately. FURBS contributions for Mr Parton are paid to the FURBS and to Mr Parton himself in the ratio 60:40. This is because the contributions are taxable benefits, so the payment to Mr Parton is to offset the higher income tax charge for which he is liable. The FURBS documents oblige Corp to fund an unapproved life assurance scheme, which is to provide a lump sum on death in service of four times basic salary and a widow's pension of four-ninths of final pensionable salary. The service agreement contains a provision entitling Corp to make a payment in lieu of notice (a "PILON" payment) if it terminates the service agreement without giving Mr Parton 12 months' notice. The PILON payment comprises the following amounts for the notice period (or the unexpired balance of it: (i) base salary, (ii) 100 per cent. of contributions to his FURBS, (iii) the cost (to the employer) of providing benefits (other than bonus and pension) (which cost Corp may set at 10 per cent. of Mr Parton's base salary) and (iv) 80 per cent. of average core bonuses awarded in the last three completed financial years immediately preceding the financial year in which the employment terminates (pro rata for the PILON period). In addition, the service agreement includes a change of control clause which defines "Change of Control" as (a) the acquisition by any person or persons of the power to control the composition of the board of directors or direct the conduct of the company's business or (b) the determination by the remuneration committee that a change of control has occurred. If within 12 months of a Change of Control (i) Mr Parton's employment is terminated (other than for cause or following prolonged sickness), or (ii) he ceases to be a director (other than 155

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- through voluntary resignation or as a consequence of termination for cause/prolonged sickness), or (iii) Mr Parton terminates his employment for one or more "good reasons" (comprising material reduction of his status following changes by Corp of his duties, a failure by Corp materially to comply with its contractual obligations or a failure by Corp to enter into a new arrangement on the same terms) then Mr Parton will be entitled to liquidated damages. The liquidated damages comprise: his basic salary for his notice period, his pension loss (comprising 166 per cent. of the cash equivalent transfer value of the pension arrangements he would have accrued in the notice period under the main UK Plan plus 100 per cent. of the contributions which would have been paid to his FURBS), the cost to Corp providing other benefits (excluding pension and bonus) in the notice period (which cost Corp may determine at 10 per cent. of Mr Parton's base salary), a bonus equal to his basic annual salary plus the value of share rights foregone. Any payment will be subject to tax. There is a provision to place Mr Parton on garden leave if notice to terminate is served by either party. Garden leave does not trigger the PILON payment. Mr Parton is subject to post-termination protective covenants relating to non-solicitation of clients and managerial or technical employees, non-dealing with clients and not competing with the Group's business. All the covenants are stated to last for 12 months. Mr Parton is a member of the Retention and Emergence plan (described in Part D.10 of this Section). The plan promises a bonus equal to 150 per cent. of his base salary, paid in four equal tranches, two of which have been paid. The third tranche, payable after restructuring, has yet to be paid but the fourth tranche is to be waived. MICHAEL DONOVAN, as Chief Operating Officer, has a service agreement dated 1 June 2002 with plc, whose obligations were guaranteed by Marconi Communications Limited. The agreement was novated to Corp on 17 March 2003 (with Marconi Communications Limited continuing to act as guarantor). The agreement lasts until Mr Donovan's 62nd birthday but may be terminated earlier by Corp on 12 months' notice and by Mr Donovan on 6 months' notice. The basic salary is L400,000 per annum, which is reviewable on 1 July 2003 (and thereafter annually). Mr Donovan is eligible to participate in such incentive and stock option plans as are generally offered to employees of Mr Donovan's status. His agreement provides for a company car and private medical health care for himself and his family. Mr Donovan is entitled to participate in the UK Plan (described in Part D.11 of this Section) to which he contributes three per cent. of his basic salary (up to a maximum of 15 per cent. of the Inland Revenue earnings cap). As a consequence of the earnings cap restricting the amount an employer can pay into an exempt approved pension plan, Mr Donovan also has a funded unapproved retirement benefits scheme (a "FURBS"). The documentation setting out Mr Donovan's FURBS was amended by the terms of his service agreement (detailed below). Mr Donovan's FURBS is funded on a defined benefit basis, with projected benefits of two-thirds of his final pensionable salary. The current contribution rate (to be reviewed in May 2003) is 39 per cent. of his base salary (although while Mr Donovan is posted to the US, the rate is 46 per cent., owing to local tax legislation). If Mr Donovan leaves service on the grounds of ill-health and receives an immediate ill-health pension from the UK Plan, the total pension payable to him will be two-thirds of his final pensionable salary of the date of leaving. The actual FURBS documentation refers to a defined contribution arrangement (based on 35 per cent. of that part of Mr Donovan's salary in excess of the earnings cap). In addition, it contains an unfunded promise to make up the difference (if any) between the level of benefits under the UK Plan and the FURBS and the benefits to which Mr Donovan would have been entitled had he remained in two pension schemes operated by group companies of his previous employer (BAE Systems). A decision was taken to fund the FURBS on a defined benefit basis rather than to risk the unfunded top-up obligation being called upon and Mr Donovan's service agreement (which sets out the defined benefit basis of the plan) amends the earlier, defined contribution wording. FURBS contributions for Mr Donovan are paid into the FURBS and to Mr Donovan himself in the ratio of 60:40 (or as necessary under US tax law). This is because the contributions are taxable benefits, so the payment to Mr Donovan is to offset the higher income tax charge for which he is liable. The FURBS documents oblige Corp to fund an unapproved life assurance scheme, which is to provide a lump sum on death in service or four times basic salary and a widow's pension of four-ninths of final pensionable salary. The service agreement contains a provision entitling Corp to make a payment in lieu of notice if it terminates the service agreement without giving Mr Donovan 12 month's notice. The PILON payment comprises the same elements as Mr Parton's agreement (described above) save that the compensation for loss of pension benefits differs. Instead of receiving 100 per cent. of the employer contribution to his FURBS, Mr Donovan is entitled to 156

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- an amount equal to 166 per cent. of the cash equivalent transfer value of the additional pension benefits (net of income tax) which Mr Donovan would have accrued in the UK Plan if he had been asked to work his notice. In addition, Mr Donovan would be entitled to an amount equal to 166 per cent. of the net contributions which Corp would have paid to his FURBS during the unexpired noticed period. In addition, the contract includes a change of control clause. "Change of control" is defined as (i) the acquisition by a person of the power to control the composition of the board (or to secure the company's affairs are conducted in accordance with that person's wishes) or (ii) the persons who were on Corp's board of directors at the date of the agreement (or persons subsequently appointed by two-thirds of those directors) (the "Incumbent Board") ceasing for any reason to constitute the majority of Corp's board, or (iii) a "Business Reconstruction" occurs (widely defined to include any disposition of all or substantially all the of the equity in or the business and/or assets of Corp the company to any person to other than another group company (or any other similar transaction)). The definition of Business Reconstruction is, however, qualified so that, for example, there is no trigger if there is an entity immediately resulting from the reorganisation which has shareholders who (before and after the reconstruction) hold more than 50 per cent. of the shares (in similar proportions), does not have one person holding 20 per cent. or more of the voting rights and where the majority of the board of the resulting entity were members of the Incumbent Board who decided upon the reconstruction, or (iv) the company's shareholders approve the dissolution of the company (except pursuant to a Business Reconstruction fulfilling certain criteria). If within 12 months of a change of control, Mr Donovan's employment is terminated or he resigns for one or more specified "good reasons", he will be entitled to liquidated damages. The damages are calculated on the same basis as the PILON payment, save that there is compensation for loss of share schemes rights and there is an assumed bonus equal to one year's salary. There is provision to place Mr Donovan on garden leave if notice to terminate was served by either party. Garden leave does not trigger the PILON payment. Mr Donovan is subject to post-termination protective covenants relating to non-solicitation of clients and managerial or technical employees, non-dealing with clients and not competing with the Group's business. All the covenants are stated to last for twelve months, save for the non-compete clause which lasts for six months. Mr Donovan also has an arrangement relating to his location in the United States, which contains expatriate arrangements to cover relocation, housing, exchange rate fluctuation, flights for himself and his family and matters common to expatriate terms for senior executives. Mr Donovan is a member of the Retention and Emergence Plan (described in Part D.10 of this Section). The plan promises a bonus equal to 150 per cent. of his base salary, paid in four each tranches, two of which have been paid. The third tranche, payable after restructuring, has yet to be paid but the fourth tranche is to be waived. CHRISTOPHER HOLDEN, as Interim Chief Financial Officer, has a service agreement with Corp dated 13 December 2002 (as varied by a deed dated 28 January 2003). His role is as interim chief financial officer of Corp and plc, but Corp can re-assign him to another position, so long as it is commensurate with his status and seniority. The contract is for a fixed term, commencing on 14 November 2002 and ending on 30 June 2003. The basic salary is L25,000 per month, inclusive of directors' fees. Mr Holden is entitled to join the UK Plan but there are no other pension or incentive arrangements set out in his contract. Corp is entitled to terminate Mr Holden's employment immediately by making a payment in lieu of the base salary he would have otherwise earned in the balance of his fixed term. Mr Holden is subject to post termination protective covenants, all of which are to last for six months following the termination date. The covenants cover non-solicitation of clients, non-dealing with clients, non-poaching of managerial or technical employees and non competing with Group companies. JOHN DEVANEY, as Chairman, has a service agreement with Corp dated 14 March 2003 to which plc is also a party to take the benefits of Mr Devaney's covenants. The agreement is effective on and from 16th December 2002. All payments and benefits due to Mr Devaney are payable by Corp. The agreement is terminable by either party on three months' notice and terminates automatically on Mr Devaney's 65th birthday. Mr Devaney's salary is L250,000 per annum and he is required to devote three days per week to his duties. Mr Devaney is entitled to participate in the Senior Management Share Option Plan and to membership of the UK Plan. His benefits comprise private medical insurance, life insurance, company car and fifteen working days' holiday per annum. 157

EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- The agreement lists the companies in respect of which Mr Devaney is already a director and permits him to continue those other interests, so long as they do not affect his obligations under the service agreement. Consent may not be unreasonably withheld or delayed should Mr Devaney wish to be interested in companies substituted for, or additional to, the agreed list of companies from time to time provided that his duties are not adversely affected and that he does not contravene the overriding obligation not to hold more than 5 per cent in any class of securities in any competing business. There are no clauses relating to payments in lieu of notice or change of control and there are no restrictive covenants. Each of the other Directors of Corp and plc has terms of appointment as follows: KENT ATKINSON was appointed a non-executive director of Corp and plc on 16 December 2002 for an initial term of three years (subject to the Articles and described below). Mr Atkinson's duties include chairmanship of the audit and membership of the nomination and remuneration committees. His fee is L30,000 per annum (which includes the fee payable as a non-executive director of plc) based on him spending two days per month on his duties for both companies. Mr Atkinson will also be entitled to a fee of L15,000 per annum for so long as he serves as chairman of the audit committee. Although he will not normally be expected to provide his services for more than 52 days per annum, he is entitled to a fee of L1,500 per day for each additional day worked over the two day per month threshold. These fees are reviewable annually on 1 July and Corp will reimburse business expenses. Mr Atkinson will also be entitled to an advance fee for each of the first three years of his appointment. The fee payable will be L100,000 for the first year and L30,000 for each of the next two years which will be net of any tax and national insurance contributions. The net amount of each year's fee will be invested in Corp Shares. Mr Atkinson has agreed to hold the Corp Shares acquired with the first year's advance fee for three years from the date of his appointment and the Corp Shares acquired with each of the next two years' payment for at least one year. If Mr Atkinson's appointment terminates in any year for which an advance fee has been paid he is obliged to repay a pro-rated amount of that year's fee. There is no other remuneration nor benefits. DEREK BONHAM was appointed as a non-executive director of plc on 10 April 2001 and became interim Chairman on 4 September 2001. As from 31 March 2002, his fee for this role was fixed at L180,000 per annum and his benefits include reimbursement of expenses. He ceased to be Chairman on 16 December 2002 and it is currently anticipated that he will remain a non-executive director of plc until implementation of the plc scheme when he will resign as a director of plc. He is currently chairman of plc's remuneration committee. Mr Bonham has agreed that his fee as a non-executive director of plc will be paid by Corp (in consideration of the value to Corp of Mr Bonham agreeing to continue providing his services to plc). WERNER KOEPF was appointed a non-executive director of Corp and plc on 16 December 2002 for an initial term of three years (subject to the Articles and described below). Mr Koepf's duties include membership of the audit, remuneration and nomination committees. His fee is L30,000 per annum (which includes the fee payable as a non-executive director of plc) based on him spending two days per month on his duties for both companies. Although he will not normally be expected to provide his services for more than 52 days per annum, he is entitled to a fee of L1,500 per day for each additional day worked over the two day per month threshold. These fees are reviewable annually on 1 July and Corp will reimburse business expenses. Mr Koepf will also be entitled to an advance fee for each of the first three years of his appointment. The fees payable will be L100,000 for the first year and L30,000 for each of the next two years which will be net of any tax and national insurance contributions. The net amount of each year's fee will be invested in Corp Shares. Mr Koepf has agreed to hold the Corp Shares acquired with the first year's advance fee for three years from the date of his appointment, and the Corp Shares acquired with each of the next two year's payment for at least one year. If Mr Koepf's appointment terminates in any year for which an advance fee has been paid he is obliged to repay a pro-rated amount of that year's fee. There is no other remuneration nor benefits. KATHLEEN RUTH FLAHERTY'S appointment as a non-executive director of Corp will take effect on Listing of the New Shares, the New Notes and the Warrants for an initial term of three years (subject to the Articles and as described below). Ms Flaherty's duties include membership of the remuneration and nomination committees. Her fee is L30,000 per annum based on her spending two days per month on her duties for Corp. She is entitled to a fee of L1,500 per day for each additional day over the two days per month threshold. Her fee is reviewable 158

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- annually on 1 July and Corp will reimburse business expenses. Ms Flaherty will also be entitled to an advance fee of L30,000 for each of the first three years of her appointment which will be net of any tax and national insurance contributions. The net amount of each year's fee will be invested in Corp Shares. Ms Flaherty has agreed to hold the Corp Shares acquired with the first year's advance fee for three years from the date of her appointment and the Corp Shares acquired with each of the next two years' payment for one year. If Ms Flaherty's appointment terminates in any year for which an advance fee has been paid she is obliged to repay a pro-rated amount of that year's fee. There is no other remuneration nor benefits. IAN MCMASTER CLUBB'S appointment as a non-executive director of Corp will take effect on Listing of the New Shares, the New Notes and the Warrants for an initial term of three years (subject to the Articles and as described below). Mr Clubb's duties include chairmanship of the remuneration committee and membership of the audit and nomination committees. His fee is L30,000 per annum based on his spending two days per month on his duties for Corp. Mr Clubb will also be entitled to a fee of L10,000 per annum for so long as he serves as chairman of the remuneration committee. He is entitled to a fee of L1,500 per day for each additional day over the two day per month threshold. His fee is reviewable annually on 1 July and Corp will reimburse business expenses. Mr Clubb will also be entitled to an advance fee of L30,000 for each of the first three years of his appointment which will be net of any tax and national insurance contributions. The net amount of each year's fee will be invested in Corp Shares. Mr Clubb has agreed to hold the Corp Shares acquired with the first year's advance fee for the three years from the date of his appointment and the Corp Shares acquired with each of the next two years' payment for one year. If Mr Clubb's appointment terminates in any year for which an advance fee has been paid he is obliged to repay a pro-rated amount of that year's fee. There is no other remuneration nor benefits. The existing articles provide for the removal of a director by (amongst other causes) the written requirement of at least three-quarters of the other Corp Directors or by ordinary resolution of the shareholders. Conditional on the allotment of the New Shares, new articles of association will be adopted which amend these provisions by requiring special notice to be given of the ordinary resolution and furthermore, providing for the removal of a director by extraordinary resolution. For the financial year ended 31 March 2002, the aggregate remuneration (including salaries, fees, pension contributions, shares payments and benefits in kind) granted to the Directors by plc (no fees were payable in respect of Corp) was approximately L2,287,000. It is estimated that for the financial year ending 31 March 2003, under arrangements in force at the date of this document, the aggregate remuneration of the Directors of Corp will be approximately L5,165,000. Save for an agreement by Michael Parton and by Michael Donovan to waive the first two payments under an annual incentive bonus plan (20 per cent. of basic salary) and the last payment under of the R&E Plan (37.5 per cent. of basic salary), there is no arrangement under which a Director has waived or agreed to waive future emoluments nor have there been any such waivers during the financial year immediately preceding the date of this document. There are no outstanding loans or guarantees granted or provided by any member of the Group to, or for the benefit of, any of the Directors. b. Directors' new service agreements With effect from the Effective Date, service agreements of the following Executive Directors with Corp replace their existing service agreements and will take effect as follows: MICHAEL PARTON, as Chief Executive Officer, will have a service agreement which will take effect from the Effective Date. The agreement will last until Mr Parton's sixty-second birthday but may be terminated earlier by Corp giving twelve months' notice and by Mr Parton giving six months' notice. The basic salary will be L525,000 per annum (inclusive of directors' fees), which will be reviewable on 1st July 2004 (and thereafter annually) and Mr Parton is eligible to participate in the senior management share option plan. His agreement provides for participation in a company car scheme and private medical healthcare for himself and his family. Mr Parton will be entitled to participate in the UK Plan (described in Part D.11 of this Section) to which he contributes 3 per cent. of his basic salary (up to a maximum of 15 per cent. of the Inland Revenue earnings cap, 159

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- which is L97,200 in the 2002/2003 tax year). As a consequence of the earnings cap restricting the amount an employer can contribute into an exempt approved pension plan, Mr Parton will continue to have a funded unapproved retirement benefits scheme, to which Corp will contribute an amount equal to 21 per cent. of his basic salary (with a further 14 per cent. of his basic salary being paid to Mr Parton). In addition, and as compensation for Mr Parton changing a defined benefit pension arrangement into a defined contribution plan in 2002, Corp has agreed to make net contributions of L88,250 to the FURBS and associated non-pensionable allowances of L58,833.33 to Mr Parton himself on 15 April 2003, 15 July 2003, 15 October 2003 and 15 January 2004. The payments are conditional on Mr Parton remaining in employment with Corp and if his employment is terminated (other than for cause), any payments which have not been made on or before the termination date will become due immediately. FURBS contributions for Mr Parton are paid to the FURBS and to Mr Parton himself in the ratio 60:40. This is because the contributions are taxable benefits, so the payment to Mr Parton is to offset the higher income tax charge for which he is liable. The FURBS documents oblige Corp to fund an unapproved life assurance scheme, which is to provide a lump sum on death in service of four times basic salary and a widow's pension of four-ninths of final pensionable salary. The service agreement will contain a provision entitling Corp to make a payment in lieu of notice if it terminates the service agreement without giving Mr Parton 12 months' notice. The amount of the payment is at the reasonable discretion of the remuneration committee which is to consider the relationship between the Group's and Mr Parton's performance. The maximum PILON payment may not exceed the aggregate of the following amounts for the notice period (or the unexpired balance of it): (i) base salary (ii) 166 per cent. of the cash equivalent transfer value of the pension contributions (net of tax) which would have accrued in the UK Plan; (iii) 100 per cent. of the gross contributions which Corp would have paid in respect of Mr Parton's FURBS and (iv) the cost (to Corp) or providing benefits (other than bonus, pension and incentive entitlements) (which cost Corp may set at 10 per cent. of Mr Parton's base salary). If Corp does not make a full PILON payment (i.e. if the remuneration committee reduces the amount payable), Mr Parton's protective covenants will enure for a proportionately shorter period after the termination of his employment. In addition, the service agreement will include a change of control clause which provide Mr Parton with a right to a payment if, following the Restructuring, there is a change of control of Corp and one of the events described below occurs. Change of control is defined as the acquisition of the power to control the composition of the board of Corp or (by a variety of means) that its affairs are conducted in a certain manner. If, immediately following an acquisition of Corp's shares, the shares in the acquiring company are all held by the holders of the shares of Corp immediately prior to the acquisition in materially the same proportion as prior to the acquisition, then that will not constitute a change of control. If the terms of the clause are triggered, Mr Parton will be entitled to a payment calculated on the same basis as the PILON payment. The events are: (a) Corp or any other Group Company terminating employment (other than for cause); (b) Mr Parton ceasing to be a director of Corp other than by reason of his voluntary resignation; or (c) if Mr Parton terminates the service agreement for a "good reason". The good reasons are one or more of the following: - a failure to maintain Mr Parton in the role (or a substantially equivalent position, with Corp or any Group Company) which he held immediately prior to the change of control; - an adverse change of material consequence in the nature or scope of the authorities, powers, functions, responsibilities or duties attached to the position which Mr Parton held immediately prior to the change of control; - a reduction in the aggregate of Mr Parton's basic annual salary and share based incentives and other benefits received from Corp or any Group Company, or the termination or denial of Mr Parton's rights to employee benefits or a substantial reduction in the scope or value thereof where such reduction is not applied to other employees of a similar status and seniority to Mr Parton; - a change in the scope of the business or other activities for which Mr Parton was responsible immediately prior to the change of control, which has rendered Mr Parton substantially 160

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- unable to carry out, has substantially hindered Mr Parton's performance of, or has caused him to suffer a substantial reduction in, any of the authorities powers, functions, responsibilities or duties attached to his position held; - Corp requiring Mr Parton to have his principal location of work changed to any location that is in excess of 25 miles from its location immediately prior to the change of control without his prior written consent; or - any material breach of the service agreement by Corp or any successor. In each case of a "good reason", however, Mr Parton must first have notified Corp of the act or omission and Corp must have failed within 10 calendar days to gain Mr Parton's agreement to any change or must in that period have remedied the act or omission. There will be a provision to place Mr Parton on garden leave if notice to terminate is served by either party (without triggering any PILON payment). Mr Parton is subject to post-termination protective covenants relating to non-solicitation of clients and managerial or technical employees, non-dealing with clients and not competing with the Group's business. All the covenants are stated to last for 12 months, save for that relating to non-competing, which lasts for six months. See the comments relating to PILON payments for a potential reduction in the periods of such protective covenants. Mr Parton is a member of the Retention and Emergence Plan (described in Part D.10 of this Section). The plan promises a bonus equal to 150 per cent. of his base salary, paid in four each tranches, two of which have been paid. The fourth tranche is to be waived. MICHAEL DONOVAN, as Chief Operating Officer, will have a service agreement with Corp which will take effect on the Effective Date. The agreement will last until Mr Donovan's sixty-second birthday but may be terminated earlier by Corp giving twelve months' notice and by Mr Donovan giving six months' notice. The basic salary is L400,000 per annum (inclusive of director's fees), which will be reviewable on 1 July 2004 (and thereafter annually) and Mr Donovan will be eligible to participate in the senior management share option plan. His agreement will provide for participation in a company car scheme and private medical healthcare for himself and his family. Mr Donovan will be entitled to participate in the UK Plan (described in Part D.11 of this Section) to which he contributes 3 per cent. of his basic salary (up to a maximum of 15 per cent. of the Inland Revenue earnings cap). As a consequence of the earnings cap restricting the amount an employer can pay into an exempt approved pension plan, Mr Donovan also will have a funded unapproved retirement benefits scheme. Mr Donovan's FURBS is funded on a defined benefit basis, with projected benefits of two-thirds of his final pensionable salary. The pension will be made up from Mr Donovan's benefits under the UK Plan, the FURBS, two BAE pension plans and any other retained benefits he may have. If Mr Donovan retires on or after his fifty-fifth birthday, there will be no actuarial reduction in the value of his benefits. The current contribution rate (to be reviewed in May 2003) is 39 per cent. of his base salary (although while Mr Donovan is posted to the US, the rate is 46 per cent., owing to local tax legislation). If Mr Donovan leaves service on the grounds of ill-health and receives an immediate ill-health pension from the UK Plan, the total pension payable to him will be two-thirds of his final pensionable salary of the date of leaving. FURBS contributions for Mr Donovan are paid into the FURBS and to Mr Donovan himself in the ratio of 60:40 (or as necessary under US tax law). This is because the contributions are taxable benefits, so the payment to Mr Donovan is to offset the higher income tax charge for which he is liable. The FURBS documents oblige Corp to fund an unapproved life assurance scheme, which is to provide a lump sum on death in service or four times basic salary and a widow's pension of four-ninths of final pensionable salary. The service agreement will contain a provision entitling Corp to make a payment in lieu of notice if it terminates the service agreement without giving Mr Donovan 12 months' notice. The PILON payment comprises the following amounts for the notice period (or the unexpired balance of it): (i) base salary (ii) 166 per cent. of the cash equivalent transfer value of the pension contributions (net of tax) which would have accrued in the UK Plan; (iii) 166 per cent. of the net contributions which Corp would have paid into Mr Donovan's FURBS and (iv) the 161

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- cost (to Corp) or providing benefits (other than bonus, pension and incentive entitlements) (which cost Corp may set at 10 per cent. of Mr Donovan's base salary). The PILON payment would be taxable in Mr Donovan's hands. In addition, the service agreement will include a change of control clause which provide Mr Donovan with a right to a payment if, following the Restructuring, there is a change of control of Corp and one of the events described below occurs. Change of control is defined as the acquisition of the power to control the composition of the board of Corp or (by a variety of means) that its affairs are conducted in a certain manner. If, immediately following an acquisition of Corp's shares, the shares in the acquiring company are all held by the holders of the shares of Corp immediately prior to the acquisition in materially the same proportion as prior to the acquisition, then that will not constitute a change of control. If the terms of the clause are triggered, Mr Donovan will be entitled to a payment calculated on the same basis as the PILON payment. The events are: (a) Corp or any other Group Company terminating employment (other than for cause); (b) Mr Donovan ceasing to be a director of Corp other than by reason of his voluntary resignation; or (c) if Mr Donovan terminates the service agreement for a "good reason". The good reasons are one or more of the following; - a failure to maintain Mr Donovan in the role (or substantially equivalent position, with Corp or any Group Company) which he held immediately prior to the change of control; - an adverse change of material consequence in the nature or scope of the authorities, powers, functions, responsibilities or duties attached to the position which Mr Donovan held immediately prior to the change of control; - a reduction in the aggregate of Mr Donovan's basic annual salary and share based incentives and other benefits received from Corp or any Group Company, or the termination or denial of Mr Donovan's rights to employee benefits or a substantial reduction in the scope or value thereof where such reduction is not applied to other employees of a similar status and seniority to Mr Donovan; - a change in the scope of the business or other activities for which Mr Donovan was responsible immediately prior to the change of control, which has rendered Mr Donovan substantially unable to carry out, has substantially hindered Mr Donovan's performance of, or has caused him to suffer a substantial reduction in, any of the authorities powers, functions, responsibilities or duties attached to his position held - Corp requiring Mr Donovan to have his principal location of work changed to any location that is in excess of 25 miles from its location immediately prior to the change of control without his prior written consent; or - any material breach of the service agreement by Corp or any successor. In each case of a "good reason", however, Mr Donovan must first have notified Corp of the act or omission and Corp must have failed within 10 calendar days to gain Mr Donovan's agreement to any change or must in that period have remedied the act or omission. There will be a provision to place Mr Donovan on garden leave if notice to terminate is served by either party (without triggering the PILON payment). Mr Donovan is subject to post-termination protective covenants relating to non-solicitation of clients and managerial or technical employees, non-dealing with clients and not competing with the Group's business. All the covenants are stated to last for 12 months, save for that relating to non-competing, which lasts for six months. Mr Donovan also will have an arrangement relating to his location in the United States, which contains expatriate arrangements to cover relocation, housing, exchange rate fluctuation, flights for himself and his family and matters common to expatriate terms for senior executives. 162

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART E -------------------------------------------------------------------------------- Mr Donovan is a member of the Retention and Emergence Plan (described in Part D.10 of this Section). The plan promises a bonus equal to 150 per cent. of his base salary, paid in four each tranches, two of which have been paid. The fourth tranche is to be waived. JOHN DEVANEY'S service agreement with Corp dated 14 March 2003 will not change. CHRISTOPHER HOLDEN'S service agreement with Corp dated 13 December 2002 (as varied by a deed dated 28 January 2003) will not change. No changes are planned to take effect from the Effective Date, in respect of the terms of appointment of the Chairman and each of the Non-Executive Directors.

E.2 TRUSTEES OF THE BONDS The Law Debenture Trust Corporation p.l.c. has a material interest in both of the Schemes by reason of being a Scheme Creditor in each Scheme. Law Debenture Trust Company of New York will be appointed New Senior Notes Trustee in respect of the New Senior Notes to be issued under the Schemes and The Law Debenture Trust Corporation p.l.c. will be appointed Security Trustee under the Security and Intercreditor Trust Deed. Law Debenture Trust Company of New York is an affiliate of The Law Debenture Trust Corporation p.l.c. The Bank of New York has a material interest in both of the Schemes by reason of being a Scheme Creditor in each Scheme. The Bank of New York will be appointed as Distribution Agent and as ADR Depositary in respect of any ADRs to be issued under the Schemes. The Eurobond Trustee and the Yankee Bond Trustee also have a material interest in the Schemes by reason of their being owed sums in respect of fees, costs, expenses and liabilities, amounting to a total of L155,159.92 as at 18 March 2003 in respect of the Eurobond Trustee, and a total of L144,450.96 as at 14 March 2003 in respect of the Yankee Bond Trustee (both figures inclusive of VAT). These fees, costs, expenses and liabilities were incurred as a result of the Eurobond Trustee and Yankee Bond Trustee's roles during the drafting and negotiation of the Schemes. If the Schemes are implemented then these fees, costs, expenses and liabilities will be paid in priority to Scheme Claims. Affiliates of the Eurobond Trustee, through such affiliates acting as New Senior Notes Trustee and Security Trustee, and the Yankee Bond Trustee, through its acting as Distribution Agent and ADR Depositary, will be entitled to the payment of fees and reimbursement of expenses incurred in performing their respective duties under these ongoing roles. 169

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- F. RISK FACTORS This Part F sets out the principal risk factors affecting the Group and should be read in conjunction with all other information contained in this document. Additional risks and uncertainties not presently known to the Group or that the Group currently deems immaterial may also have a material adverse effect on the business, financial condition or results of operations of the Group. Except in Part F.1 and as the context otherwise requires, this Part F assumes that the Schemes will be implemented in accordance with their terms and does not include risk factors about the Group in the event that either or both of the Schemes do not become effective (which are discussed in the letter from the Chairman of plc and of Corp in Section 1). All statements in this document (other than parts II and III) are to be read subject to, and are qualified in their entirety by, the matters referred to in this Part F. For ease of reference only, the risk factors set out below have been grouped into the following four categories: a. Risks related to a failure to implement or a delay in implementing the Restructuring; b. Risks arising from implementation of the Restructuring; c. Operating risks; and d. Risks related to ownership of the New Shares, the New Notes and the Warrants. F.1 RISKS RELATED TO A FAILURE TO IMPLEMENT OR A DELAY IN IMPLEMENTING THE RESTRUCTURING ESOP DERIVATIVE BANKS MAY BE ABLE TO TERMINATE THEIR STANDSTILL UNDERTAKINGS PRIOR TO IMPLEMENTATION OF THE RESTRUCTURING. As discussed in Part D.2 of this Section, plc is the guarantor with respect to the equity derivative transactions with the ESOP Derivative Banks. The ESOP Derivative Banks have previously asserted that they also have claims against certain Group operating companies, including Corp, based on the ESOP Funding Letters executed by those companies. Under the terms of the ESOP Settlement Agreement, Corp will pay a total of L35 million to the ESOP Derivative Banks in full and final settlement of their ESOP related claims against the Group. The settlement is conditional upon the Corp Scheme becoming effective and, in the interim, the ESOP Derivative Banks have agreed to a standstill, namely that they will not commence or further any claims or proceedings against Bedell Cristin Trustees Limited, plc or any Group operating companies (or any of their respective directors and officers) under the ESOP Funding Letters (including releases thereof), the ESOP Derivative Transactions or the plc guarantee of the ESOP Derivative Transactions. The standstill terminates on the occurrence of one of the relevant events set out in the ESOP Settlement Agreement, including (a) the further release of ESOP Funding Letters in certain circumstances, (b) enforcement of the interim security, (c) the Corp Scheme not obtaining the requisite approval at the Scheme Meeting, (d) the Court sanction for the Corp Scheme not being obtained, (e) a demand being made by the agent for the repayment of the Bank Facility, (f) an insolvency event occurring in relation to Corp or, subject to certain limitations, plc and (g) the Effective Date for the Corp Scheme not occurring on or before 31 December 2003. EFFECTIVENESS OF THE SCHEMES REQUIRES THE APPROVAL OF CREDITORS AND SANCTION BY THE COURT. In order for the Corp Scheme and the plc Scheme to become effective, they must be approved by Scheme Creditors of Corp and plc, respectively, as described in this document. Although each of the then members of the Informal Committee of Bondholders and certain members of the Co-ordination Committee indicated as at 13 December 2002 that it was their current intention to vote in favour of the Schemes, they are not bound to do so and in any event do not represent a sufficient proportion of the Scheme Creditors to ensure that the Schemes will be approved. Each of the ESOP Derivative Banks has provided a voting undertaking in relation to the Schemes (as described in more detail in Appendix 19). The willingness of other creditors to vote in favour of the Schemes will be dependent on their assessment of what they would be likely to receive if the Restructuring was successfully concluded, which will depend among other things on their view of the prospects with respect to the Group's future results of operations, financial condition and working capital position and their assessment of 170

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- what they would be likely to receive in insolvency proceedings in connection with the Group. Accordingly, there can be no assurance that the Scheme Creditors will vote to approve either of the Schemes. In addition, for the Schemes to become effective, they must receive the sanction of the Court, as described in this document. The Court will not sanction either of the Schemes unless it is satisfied that the proposed arrangements are fair to the creditors whose claims are being compromised pursuant to the Schemes. There can be no assurance that the court will determine that the Schemes are fair to creditors or that the Court will not conclude that there are other reasons why the Schemes should not be approved. EFFECTIVENESS OF EACH OF THE SCHEMES WILL DEPEND UPON THE GRANTING OF AN ORDER BY A US BANKRUPTCY COURT. Even if one or both of the Schemes are approved by Scheme Creditors and sanctioned by the English Court, the necessary steps required to make either of them effective will not be taken unless a permanent injunction in respect of the relevant Scheme is granted by a US Bankruptcy Court under Section 304 of Title 11 of the United States Code. The US Bankruptcy Court will not grant such an injunction unless it is convinced that the relevant Scheme will abide by fundamental standards of procedural fairness and is not repugnant to any fundamental principle of US law. There can be no assurance that the US Bankruptcy Court will determine that this standard has been met, or that the US Bankruptcy Court will not conclude that there are other reasons why the order should not be granted. THE CORP SCHEME MAY BE IMPLEMENTED EVEN IF THE PLC SCHEME IS NOT, IN WHICH CASE CORP SCHEME CREDITORS WILL RECEIVE LESS SCHEME CONSIDERATION THAN IF BOTH SCHEMES BECOME EFFECTIVE, AND PLC WILL BE FORCED INTO AN INSOLVENCY PROCEEDING. The effectiveness of the plc Scheme is conditional on the Corp Scheme becoming effective, but the effectiveness of the Corp Scheme is not conditional on the plc Scheme becoming effective. Because Scheme Creditors must vote on each of the Corp Scheme and the plc Schemes independently, the Corp Scheme may be approved by Scheme Creditors, while the plc Scheme is not. Moreover, it is possible that the Court may sanction one Scheme but not the other, or that the US Bankruptcy Court may issue an injunction in respect of one Scheme but not the other. If the Corp Scheme becomes effective but the plc Scheme does not, Corp Scheme Creditors will receive less, and Corp Scheme Creditors that are also plc Scheme Creditors could receive significantly less, Scheme Consideration than if both Schemes become effective. There are two reasons for this. First, Corp itself is expected to be a significant plc Scheme Creditor, and the portion of the plc Scheme Consideration that Corp would receive in respect of its claim against plc will not be available for distribution to Corp Scheme Creditors pursuant to the Corp Scheme unless the plc Scheme becomes effective. Second, a significant portion of the Corp Scheme Consideration is expected to be distributed via Ancrane, a wholly owned subsidiary of plc, and this portion of the Corp Scheme Consideration will not be distributed to plc Scheme Creditors pursuant to the plc Scheme unless that Scheme becomes effective. If the plc Scheme does not become effective as and when contemplated in this document, then plc would inevitably have to enter into some form of insolvency proceeding. If the Corp Scheme has become effective, however, the portion of the Corp Scheme Consideration distributed to Ancrane would be among the assets on which plc creditors would have a claim in any such proceeding. Moreover, Corp itself would be entitled to prove its claim against plc in such an insolvency proceeding, and any recovery by Corp in that proceeding would eventually be available for distribution to Corp Scheme Creditors. CORP AND/OR PLC AND/OR THE PROSPECTIVE SUPERVISORS OF THE CORP SCHEME AND/OR THE PLC SCHEME MAY CEASE TO BE SATISFIED AS TO THE SUFFICIENCY OF THE RESERVE CLAIMS SEGMENT OF THAT SCHEME AND/OR CORP MAY CEASE TO BE OF THE OPINION THAT CORP'S WORKING CAPITAL STATEMENT REMAINS VALID. Corp will not take the necessary steps to make the Corp Scheme effective unless and until (among other things), (a) Corp has, following the passing of a unanimous Board resolution to approve the same, provided confirmation in writing to the Prospective Supervisors (for the sole benefit of the Prospective Supervisors) prior to each of (i) the release of the interim security granted by Corp through its special purpose subsidiary Highrose Limited, (ii) the Corp Scheme Meeting, (iii) the hearing to sanction the Corp Scheme and (iv) the Effective Date, to the 171

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- effect that Corp remains satisfied that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors and that Corp remains of the opinion that its statement as to the Corp Group's working capital contained in Part D.21 of this Section remains valid; and (b) the Prospective Supervisors of the Corp Scheme have provided confirmation in writing to Corp (for Corp's sole benefit) on the day of, but prior to, each of events (i) to (iv) above to the effect that they have no reason to disagree with Corp's view that the reserves built into the Corp Scheme are sufficient to meet distributions due to be made to all Corp Scheme Creditors. plc will not take the necessary steps to make the plc Scheme effective unless and until (among other things) (a) plc has, following the passing of a unanimous Board resolution to approve the same, provided confirmation in writing to the Prospective Supervisors (for the sole benefit of the Prospective Supervisors) prior to each of (i) the release of the interim security granted by Corp through its special purpose subsidiary Highrose Limited, (ii) the plc Scheme Meeting, (iii) the hearing to sanction the plc Scheme and (iv) the Effective Date, to the effect that plc remains satisfied that the reserves built into the plc Scheme are sufficient to meet distributions due to be made to all plc Scheme Creditors; and (b) the Prospective Supervisors of the plc Scheme have provided confirmation in writing to plc (for plc's sole benefit) on the day of, but prior to, each of events (i) to (iv) above to the effect that they have no reason to disagree with plc's view that the reserves built into the plc Scheme are sufficient to meet distributions due to be made to all plc Scheme Creditors. If any of the confirmations relating to the Corp Scheme is not forthcoming, neither the Corp Scheme nor the plc Scheme will proceed. If any of the confirmations relating to the plc Scheme is not forthcoming the plc Scheme will not proceed. THE INTERIM SECURITY MIGHT BE ENFORCED, OR MIGHT NOT BE RELEASED, BEFORE THE SCHEME MEETINGS. If the interim security has not been released prior to the Corp Scheme Meeting, neither Corp nor plc will proceed with their respective Schemes and, in their inevitable subsequent insolvency proceedings, the interim security would remain in place (meaning that the Bank Creditors, Secured Bondholders and Barclays Bank PLC (in its capacity as an ESOP Derivative Bank) would rank ahead of all unsecured creditors of Corp with respect to the cash held in the Lockbox Accounts, the balance of which was approximately L770,700,000 as at 27 March 2003). The occurrence of an enforcement event under the interim security (details of which are set out in Part D.1 of this Section) prior to the Scheme Meetings would have the following implications: a. the majority Bank Creditors (66 2/3 per cent. by value, which includes in its calculation bilateral and guarantee exposures of the Syndicate Banks to Corp) would be entitled to instruct the security trustee for the interim security not to release any further amounts from the Lockbox Accounts; b. the majority, currently three out of four, of the members of the Informal Committee of Bondholders would be entitled to instruct Corp and Highrose Limited not to make or request further withdrawals from the Lockbox Accounts (this is the practical equivalent of (a), but in favour of the Informal Committee of Bondholders who have not been granted rights to instruct the security trustee directly); and/or c. the majority creditors (ie. more than 50 per cent. by value of all Bank Creditors and all Secured Bondholders) would be entitled to instruct the security trustee (through the Co-ordination Committee) to enforce the interim security (in practice, Bank Creditors hold more than 50 per cent. of the value of claims and thus currently have the ability to do this). The interim security contemplates an Effective Date of the Restructuring of no later than 30 June 2003. Implementation of the Corp Scheme later than that date (or it becoming apparent that that date is no longer likely to be achieved) is one of the enforcement events in relation to the interim security. An enforcement event under the interim security would also entitle Barclays Bank PLC, the participating ESOP Derivative Bank, to terminate its Restructuring Undertaking Agreement (as described in Part D.2 of this Section) (unless it is apparent that the Corp Scheme will proceed in any case). Enforcement of the interim security would entitle any of the ESOP Derivative Banks to terminate the standstill contained in the ESOP Settlement Agreement and would also entitle them to terminate their related voting undertakings. 172

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- THE SCHEMES WILL NOT BE EFFECTIVE BY THE TIME PRINCIPAL OR INTEREST BECOMES PAYABLE UNDER THE BANK FACILITY AND/OR THE BONDS. The Bank Facility was due for repayment on 25 March 2003. Corp has not made such repayment and the facility agent has reserved all rights in this regard. Failure by Corp to repay the Bank Facility gives rise to direct rights on the part of individual Syndicate Banks to bring actions for recovery of the debt owing to them and, in addition, will, after the expiry of a five Business Day grace period, result in a cross default under the Eurobonds and Yankee Bonds. The longstop date applicable to (a) Corp's interest rate swap close-out loans with JP Morgan Chase Bank and Barclays Bank PLC, (b) Corp's terminated interest rate swap with UBS AG and (c) the closed-out equity derivative between Bedell Cristin Trustees Limited and UBS AG (in respect of which plc is the credit support provider) was also 25 March 2003, after which date such creditors may demand repayment or payment (as applicable) of principal and interest thereunder. A Yankee Bond interest payment was due on 15 March 2003. Given the expiration of the applicable 14 day grace period, non-payment of such interest will be an event of default entitling the Yankee Bond Trustee or the holders of 25 per cent. of each respective Yankee Issue to accelerate repayment of the respective Yankee Issue. Failure to pay interest under the Yankee Bonds on the due date also entitles individual holders of Yankee Bonds (under the US Trust Indenture Act of 1939 (as amended)), to sue for recovery of the missed interest coupon from Corp. The Eurobonds had an interest payment due on 30 March 2003. Failure to make the interest payment will, after a grace period of 14 days, be an event of default entitling the holders of 25 per cent. of each respective Euro Issue to instruct the Eurobond Trustee to accelerate repayment of that Euro Issue. In England, if Bondholders or Syndicate Banks sought to exercise direct rights against Corp and/or plc in respect of payment defaults it is likely that they would: (a) petition for a winding up or administration order against Corp and/or plc; or (b) seek to obtain a summary judgment for repayment of the money owed to them. Assuming a statutory demand is not required, it would take a creditor at least three weeks (from the date of service of a winding up on Corp and/or plc) to obtain an order for winding up. In practice, however, this is likely to take closer to six weeks. Administration and winding up are both class remedies in that the Court would be required to exercise its discretion in the best interests of Corp's and/or plc's creditors as a whole. Corp and plc each believe that a Court is likely to conclude that such interests would best be served by creditors being given an opportunity to consider the Corp Scheme and/or plc Scheme (as applicable) and that the Court would therefore be unlikely to allow an individual creditor to frustrate the Restructuring by obtaining an administration order or winding up order prior to the Scheme Meetings. Further, Corp and plc each believe that it is unlikely that the Court would make a winding up order after the Scheme Creditors have voted in favour of the Corp Scheme and/or the plc Scheme (as applicable). Corp would strongly oppose the making of an administration or winding up order prior to or after the Scheme Meetings and would, at the appropriate stage, actively encourage Scheme Creditors that support the Restructuring to appear and oppose such order. It is likely that it would take a creditor at least three months to obtain a summary judgment against Corp and/or plc (on the basis that a Court would be unlikely to consider the aim of defeating the Schemes to be good grounds for an expedited hearing). Levying execution against Corp's and/or plc's property in respect of any summary judgment which was obtained would require the relevant creditor to make further applications to the Court (with the attendant delays). Corp and plc believe that they would have good grounds for obtaining a stay of enforcement given that a writ of execution (or other form of execution) would otherwise prefer that creditor over the relevant Scheme Company's other creditors. In the United States, if any Scheme Creditor sought to exercise direct rights against Corp and/or plc in respect of payment defaults it is likely that they would: (a) seek to obtain a judgment for repayment of the money owing to them; and/or (b) file an involuntary petition against Corp or plc, as the case may be, under Chapter 7 (liquidation) or Chapter 11 (reorganization) of the Bankruptcy Code (three creditors, with aggregate claims of at least US$11,625 would be required to file such a petition). 173

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- Corp has submitted to New York state and federal jurisdiction in connection with the Yankee Bonds and would therefore be subject to any action filed there. In the New York state courts, an individual creditor might avail itself of a procedure allowing expeditious judgment on a claim for non-payment of money on an instrument (where such claim is for a sum that can be made certain by computation). The process to judgment would take at least 20 days. There is a small risk that, in conjunction with such action, a creditor could successfully seek to attach Corp's assets in New York (by way of ex parte application and by demonstrating sufficient risk that the asset might otherwise be dissipated or removed from the jurisdiction). If a creditor obtained a New York court judgment against Corp, then that creditor could try to enforce that judgment against Corp's US assets. Corp believes that a US federal bankruptcy court would be likely to suspend or dismiss an involuntary petition under Chapter 7 or Chapter 11 if it determined that the interests of Corp and its creditors would be better served thereby, or if a foreign proceeding (such as the Corp Scheme) was pending and the same would be consistent with the due process requirements and insolvency principles necessary to establish an ancillary proceeding under section 304 of the Bankruptcy Code (in respect of which see Appendix 21). Corp further believes that support from Scheme Creditors that support the Restructuring would be likely to have a bearing on the court's determination and would therefore actively encourage such support in defending a petition. Corp has approximately L2.2 billion outstanding under the Bank Facility which, as described above, was due for repayment on 25 March 2003. In addition, the principal amounts outstanding in respect of the Eurobonds and Yankee Bonds are E1.5 billion and US$1.8 billion respectively. Each of these obligations is guaranteed by plc. Failure to repay the Bank Facility when due would trigger a cross default under the Eurobonds and Yankee Bonds, entitling (i) the holders of 25 per cent. of each respective Yankee Issue to accelerate repayment of the relevant Bonds, and (ii) the holders of 25 per cent. of each respective Euro Issue to require the Eurobond Trustee to accelerate repayment of the relevant Bond. For the reasons described above, there can be no assurance that the Schemes will become effective, or that they will become effective within the timeframe contemplated. If the Corp Scheme does not become effective in the manner described in this document, the Group will be unable to repay the above debt to its Syndicate Banks and, when due, to its Bondholders and Corp and plc will be forced into insolvency proceedings. THE CONDITIONS TO EFFECTIVENESS OF THE SCHEMES MAY NOT BE SATISFIED BY 19 JUNE 2003. If the conditions to the effectiveness of either Scheme have not been satisfied by 19 June 2003, then the relevant Scheme will be withdrawn and not made effective. If the Corp Scheme does not become effective as and when contemplated in this document, and in any event by 19 June 2003, Corp and plc would have to enter into some form of insolvency proceedings. F.2 RISKS ARISING FROM IMPLEMENTATION OF THE RESTRUCTURING CORP WILL HAVE SIGNIFICANT DEBT OUTSTANDING AND WILL HAVE SIGNIFICANT DEBT SERVICE REQUIREMENTS, WHICH WILL MAKE THE GROUP MORE VULNERABLE TO ECONOMIC DOWNTURNS AND REDUCE ITS FLEXIBILITY. Following the Restructuring, Corp will have significant debt outstanding. This is likely to limit Corp's ability to obtain additional financing on satisfactory terms to fund working capital, capital expenditures, product development efforts and acquisitions of new assets in excess of those in its current business plan. In addition, although Corp will be permitted to meet interest payment obligations under the New Junior Notes through payment in kind by issuing additional New Junior Notes, it will otherwise be required to devote a significant proportion of its cash flow from operations to the payment of interest on its debt obligations, thereby reducing the funds available for other purposes. Corp's level of debt and the fixed nature of a portion of its debt service costs will make it more vulnerable to economic downturns, reduce its flexibility to respond to changing business and economic conditions and limit the Group's ability to pursue business opportunities, to finance its future operations or business needs and to implement its business strategies. 174

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- CORP WILL BE REQUIRED TO COMPLY WITH RESTRICTIVE COVENANTS AND AFFIRMATIVE FINANCIAL COVENANTS, WHICH WILL SIGNIFICANTLY LIMIT THE GROUP'S FINANCIAL AND OPERATIONAL FLEXIBILITY. Following the Restructuring, the terms of the indentures governing the New Notes will require Corp and its Subsidiaries to comply with restrictive covenants and the terms of the indenture governing the New Senior Notes will also require Corp to comply with certain affirmative financial covenants. In addition, the Performance Bonding Facility and the Working Capital Facility will contain restrictive covenants. The relevant covenants will become applicable immediately upon issuance of the New Notes and execution of the Working Capital Facility and the Performance Bonding Facility, as the case may be, and will, among other things, restrict the ability of Corp and its subsidiaries to incur additional indebtedness, pay dividends on and redeem shares of Corp and its subsidiaries, redeem certain subordinated obligations, make investments, undertake sales of assets, engage in certain transactions with affiliates, sell or issue capital stock of subsidiaries, permit liens to exist, operate in other lines of business, engage in certain sale and leaseback transactions and engage in mergers, consolidations or sales of all or substantially all the assets of Corp. The affirmative financial covenants in the indentures governing the New Senior Notes will apply only from and after 30 September 2005 and relate to the minimum ratio of EBITDA to gross cash finance charges and the maximum ratio of indebtedness to total EBITDA, in each case measured with respect to the Corp Group other than the Ringfenced Entities. Restrictions stemming from these covenants and from the need to comply with the affirmative financial covenants will significantly limit the Group's financial and operational flexibility, and could have a significant adverse effect on its business, results of operations and financial condition. Corp's ability to satisfy the affirmative financial covenants will be affected by changes affecting its business, results of operations and financial condition, and is thus subject to the risks described elsewhere in this Part F. A failure to comply with the restrictive covenants or the affirmative financial covenants in the indentures governing the New Notes would, if not cured or waived, constitute an event of default under the New Notes; a failure to satisfy restrictive covenants under the Working Capital Facility and/or the Performance Bonding Facility could also constitute an event of default. Subject to the Security Trust and Intercreditor Deed, the occurrence of an event of default in respect of any of these facilities would permit acceleration of all amounts borrowed thereunder, which could constitute a cross-default under the others, as well as other borrowing arrangements to which Corp or its subsidiaries are party. In such circumstances, there can be no assurance that Corp would have sufficient resources to repay the full principal amount of the New Notes and the relevant indebtedness under the Working Capital Facility and the Performance Bonding Facility in full. Holders of the Corp Shares might then receive no return on their investment. Moreover, a failure to comply with restrictive covenants constituting an event of default under the Working Capital Facility or the Performance Bonding Facility would permit the lenders under the facilities to terminate their commitments to make further extensions of credit thereunder, which would be likely to have a material adverse effect on the business, results of operations and financial condition of the Group. A NUMBER OF SIGNIFICANT GROUP CONTRACTS CONTAIN TERMINATION PROVISIONS THAT MAY BE TRIGGERED BY THE RESTRUCTURING. Some of the Group's significant contracts to supply customers with systems and services contain provisions that allow its counterparties to terminate the contracts upon a change of control or a composition with creditors or similar arrangement affecting one or more Group companies. Some or all of these counterparties may take the view that the Restructuring gives rise to a right of termination under these contracts, and may accordingly seek to terminate or renegotiate them. Early termination or significant renegotiation of these contracts, individually or in the aggregate, could have a materially adverse effect on the Group's results. Moreover, disputes over whether the Restructuring constitutes a change of control for purposes of terminating these contracts could result in litigation which would be costly, would adversely affect the Group's ability to make accurate predictions needed to run its business and could adversely affect customers' perceptions of the Group. THE GROUP WILL LOSE THE BENEFIT OF CERTAIN TAX LOSSES AS A RESULT OF THE RESTRUCTURING. In recent years, the Group has accumulated significant tax losses (and other tax credits) that are not currently recognised as deferred tax assets (see Appendix 1). As a result of the Restructuring the Group may (and, in some 175

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- cases, expects that it will) forfeit these losses, or be restricted in its ability to offset them against future profits, in various jurisdictions due to the requirements of existing and proposed tax legislation governing the use of losses after a change in ownership. The relevant jurisdictions each define a change in ownership differently, and in some cases include additional conditions which, if met for a considerable amount of time after the change in ownership, allow the losses to continue to be used. It is not therefore possible at this stage to quantify the total amount of forfeiture or restriction of the tax losses. There should be no immediate cash cost of any such forfeiture or restriction, but if profits are earned in an affected jurisdiction in the future, they could be subject to tax in full. THE EFFECTIVENESS OF THE SCHEMES IS NOT CONDITIONAL ON THE ADMISSION OF THE NEW SHARES, THE NEW NOTES OR THE WARRANTS TO THE OFFICIAL LIST OR TO TRADING ON THE LONDON STOCK EXCHANGE OR ANY OTHER SECURITIES EXCHANGE, AND PERMISSION FOR SUCH LISTING MAY BE DELAYED OR DENIED. Application has been made to the UKLA for the New Shares, the New Notes and the Warrants to be admitted to the Official List and to trading on the London Stock Exchange. While it is expected that admission to the Official List and to trading will take place on the Effective Date of the Corp Scheme, there can be no assurance that there will not be a delay in, or denial of, the admission of the New Shares, the New Notes and/or the Warrants after the Corp Scheme has become effective. If admission to the Official List and to trading on the London Stock Exchange does not take place as and when expected, Corp will use its reasonable efforts to list the New Shares, the New Notes and the Warrants in London or on another recognised stock exchange thereafter. If admission to the Official List and to trading on the London Stock Exchange does not take place on the Effective Date, this will inhibit the development of a liquid trading market for the New Shares, the New Notes and the Warrants which is likely to have a material adverse effect on their value. Additionally, if the New Notes are not listed on a recognised stock exchange within the meaning of applicable UK tax legislation, withholding tax may be payable on interest payments in respect of the New Notes. Under the terms of the New Notes, Corp will be required to pay additional amounts to the holders of the New Notes in respect of any amounts withheld. While this should not result in any direct cost to the holders of the New Notes, the payment of these "gross up" amounts will be an additional cash expense for Corp and could have a material adverse effect on Corp's financial condition and results of operations. Additionally, Corp intends to establish an ADR programme in respect of the New Shares and will apply to list such ADRs on NASDAQ. It is currently anticipated that this listing will become effective during the third calender quarter of 2003. Nevertheless, there can be no assurance that such listing will take place within the time expected, or at all. If the NASDAQ listing does not take place as and when expected, this may also inhibit the development of a liquid trading market for the ADRs, which is likely to have a material adverse effect on their value. F.3 OPERATING RISKS THE TELECOMMUNICATIONS INDUSTRY IS EXPERIENCING A SEVERE DOWNTURN, MANY OF THE GROUP'S CUSTOMERS HAVE REDUCED AND ARE CONTINUING TO REDUCE CAPITAL EXPENDITURE AND, AS A RESULT, DEMAND FOR THE GROUP'S PRODUCTS AND SERVICES HAS DECLINED AND MAY CONTINUE TO DECLINE. The telecommunications industry is currently experiencing a prolonged and severe downturn. Many of the Group's current and potential customers are network operators with high levels of indebtedness and, in some cases, emerging or weak revenue streams. Adverse economic conditions, network over-capacity due to excess build-out, lack of funding for telecommunications development and overspending on licence fees have forced network operators to undertake extensive restructuring and cost-cutting initiatives. In light of market conditions, many of the Group's customers have delayed delivery of orders previously placed and have implemented drastic reductions in capital expenditure in 2002 and 2003 as compared to 2001 and even more so in comparison with 2000, and may further reduce capital expenditure. As a result, demand for the Group's products and network roll-out services has declined. The Group's near-term financial objectives do not depend on assumptions or expectations of improvement in market conditions for the telecommunications industry or improvement in current levels of sales in the Core 176

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- businesses. However, they do assume that there will not be a further material deterioration in current market conditions or a material decline in sales levels. Additionally, achievement of the Group's longer-term financial objectives will depend upon an increase in the Group's sales volumes based on an improvement in demand for the Group's products and services, due to a recovery of the industry or otherwise. Consequently, if demand remains weak for the Group's products and services, resulting from the financial condition of the Group's customers, market and industry conditions or otherwise, it is likely to have a material adverse effect on the Group's business, results of operations and financial condition in the longer term. In particular, this may affect the Group's ability to achieve its profitability and cash flow objectives and, consequently, it may impact on the future funding requirements of the business. There can be no assurance that the telecommunications market will improve within any particular timeframe or at all, or that it will not experience subsequent, and possibly more severe and/or prolonged, downturns in the future. THE GROUP IS CURRENTLY NOT PROFITABLE AND HAS BEEN EXPERIENCING NET OPERATING CASH OUTFLOWS, AND WILL NEED TO EFFECT FURTHER CHANGES IN ITS BUSINESS IN ORDER TO ACHIEVE ITS NEAR-TERM FINANCIAL OBJECTIVES. The Group is currently not profitable and has been experiencing net operating cash outflows, and has not made an operating profit (before exceptional items and goodwill amortisation) in any fiscal quarter since the quarter ended 31 March 2002. The Group does not expect trading conditions in the telecommunications market to improve in the near-term and, as discussed above, there can be no assurance that such conditions will improve at all. Accordingly, the Group's ability to become profitable and generate positive cash flow depends significantly on improving gross margins through changes in product mix, achieving operating efficiencies, and reducing operating costs, as well as there being no further material decline in sales. a. Improvement in gross margins. The Group is aiming to improve gross margins within the Core businesses to between 24 and 27 per cent. during the year ending 31 March 2004. This target assumes that trading conditions in the telecommunications market will not change materially over this period from current conditions. The Group will accordingly seek to increase its gross margins by focusing its sales on higher margin products and through further supply chain rationalisation, lower unit product cost from on-going re-engineering of its products and further improvements and efficiencies in its manufacturing process, such as lower materials costs. If sales of higher margin products do not increase as a proportion of total sales and unit production costs do not fall as expected, the Group may not be able to achieve the improvement in gross margins it anticipates. Moreover, competitive pressures may compel the Group to reduce prices, such that gross margins remain steady or decrease, even if production costs fall. b. Reduction in operating costs (before goodwill amortisation and exceptional items). The Group is aiming to reduce the annual operating cost run-rate of the Core businesses (before goodwill, amortisation and exceptional items) to below L450 million during the financial year ending 31 March 2004, as compared with a run rate at 31 December 2002 of L550 million (before goodwill, amortisation and exceptional items). The Group will seek to achieve these cost reductions primarily through further planned reduction in headcounts as a result of further rationalisation of its activities and from natural attrition in its workforce. Reduced spending on sales and marketing initiatives and professional fees are also expected to contribute to operating cost savings. However, the actions that will be required to achieve this cost base target have not yet been fully implemented, so there is a risk that the Group may not achieve this forecast operating cost run rate or that it will not do so within the anticipated timeframe. c. No further decline in sales levels. The Group's sales have declined quarter on quarter for the past five quarters, reflecting the current downturn in the telecommunications industry as a whole. While the Group expects the market to recover at some stage, if sales in the Group's Core businesses continue to decline materially for a prolonged period, it is unlikely that the Group will be able to return to and maintain profitability or generate positive cash flow solely through gross margin improvements and operating cost reductions. 177

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- Because of these risks and uncertainties, as well as the other risks and uncertainties discussed in this Section, there can be no assurance that the Group's actual experience will correspond with its assumptions and expectations, and thus no assurance that the Group will be able to return to profitability or generate positive operating cash flows within a particular timeframe or at all. Moreover, even if the Group does attain profitability and positive operating cash flow, it may not be able to sustain or increase this from quarter to quarter or from year to year. Failure of the Group to become and remain profitable and to generate positive operating cash flow may affect its ability to pay interest and principal on the New Notes when due and will affect its ability to pay dividends on the Corp Shares. The Group may find it has limited or no ability to raise additional capital through offerings of debt or equity securities in the capital markets in the near or medium term. A RELATIVELY SMALL NUMBER OF CUSTOMERS ACCOUNT FOR A LARGE PROPORTION OF THE GROUP'S BUSINESS. IN PARTICULAR, THE LOSS OF BRITISH TELECOMMUNICATIONS PLC AS A CUSTOMER WOULD HAVE A SIGNIFICANT ADVERSE EFFECT ON THE GROUP'S RESULTS. A relatively small number of customers account for a significant proportion of the Group's turnover. In the six months ended 30 September 2002, sales to the Group's 10 largest customers represented approximately 46 per cent. of turnover of the Group's Core businesses. Because of this concentration, adverse changes that affect only a small number of customers or customer relationships could have a significant adverse effect on the Group's results. British Telecommunications plc and its subsidiaries are of particular importance to the Group. For the six months ended 30 September 2002, sales to BT represented approximately 17 per cent. of turnover of the Group's Core businesses. The loss of BT as a customer or any substantial reduction in orders by BT, particularly for the products and services of the Core businesses, would have a significant adverse effect on the Group's results. PERCEPTIONS OF UNCERTAINTY SURROUNDING THE FUTURE PROSPECTS OF THE GROUP MAY HAVE AN ADVERSE EFFECT ON ITS BUSINESS. In deciding whether or not to buy the Group's products or services, potential and existing customers are likely to consider certainty of supply as part of their procurement decision-making process. Although the Restructuring process has made it possible for the Group to continue to operate, perceptions of uncertainty may remain with respect to its financial condition and business prospects. By comparison, some competitors may have more secure balance sheets and may be perceived as more attractive suppliers. If new customers are not won, or if existing customers do not continue to place orders or are lost, it would materially adversely affect the Group's business and results of operations. In addition, perceived uncertainties associated with the Group may adversely affect existing relationships with suppliers. If suppliers become concerned about the ability of the Group to pay its creditors, they may demand shorter payment terms or not extend normal trade credit, either of which would adversely affect the Group's working capital position. The Group may not be successful in obtaining alternative suppliers if the need arises and this would adversely affect its results of operations. THE GROUP OPERATES IN A HIGHLY COMPETITIVE AND RAPIDLY CHANGING MARKET AND MAY BE UNABLE TO INVEST SUFFICIENTLY IN RESEARCH AND DEVELOPMENT TO SUSTAIN OR INCREASE SALES OF ITS PRODUCTS. The Group's products are sold in markets that are characterised by rapid adoption of new technologies, many new product introductions, shortening product lifecycles and evolving industry standards. If the Group's products cease to be competitive, the Group would be likely to lose customers and sales, which would materially adversely affect the Group's business, results of operations and financial condition. The process for developing new products based on rapidly moving technologies for broadband fixed networks and optical networks is complex and variable. It requires innovative solutions that are cost effective and based on accurate insights into technology and trends. Success depends on the timely and effective introduction of new products or enhancements to existing products in a way that meets customer needs and differentiates the Group's products from those offered by its competitors. At the same time, these new product introductions must achieve 178

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- market acceptance, anticipate and accommodate emerging industry standards and be compatible with current and competitor products. If there is an unforeseen change in one or more of the technologies affecting telecommunications the Group's products may cease to be competitive. As part of its cost reduction effort, the Group has refocused and significantly reduced its spending on research and development. The Group is aiming to reduce overall research and development spending with a target spend of around 10 per cent. of Core sales. The Group has focused more of its research and development expenditure on Core products and intends to devote an increasing proportion of spending to the optical networks and broadband routing and switching businesses. However, this may not be sufficient to maintain the competitiveness of the Group's Core products or enable it to increase its market share in key market segments. Moreover, as discussed above, the Group will be subject to restrictive covenants and other limitations and is likely to have difficulty obtaining additional sources of financing, which may affect its ability to increase spending or otherwise develop its technologies effectively. A number of the Group's competitors have greater financial and technological resources than the Group and, therefore, are in a better position to invest in developing and acquiring proprietary technology, to expand into new business segments and to increase their market shares. The Group may not be able to develop new products and services at the same rate, maintain compatibility of its products with competitors' products or keep up with technology market trends. If the Group's products and services are not competitive, it is likely that the Group will lose customers and business, its turnover will decline and its business will be materially adversely affected. THE GROUP IS DEPENDENT ON KEY MANAGEMENT PERSONNEL AND SKILLED TECHNOLOGY WORKERS WHOSE DEPARTURE COULD ADVERSELY AFFECT THE GROUP'S ABILITY TO DEVELOP ITS PRODUCTS AND OPERATE ITS BUSINESS. The overall headcount of the Group's Core business has been reduced to approximately 16,000 at 31 December 2002 from 33,000 at 31 March 2001, excluding the impact of the discontinued operations (medical systems, data systems and strategic communications). This reduction has been due to the implementation of cost-reduction plans and disposals of assets and businesses. Included in the number of employees that have left the Group are managers with many years of experience in the management and operations of the Group's business as well as highly skilled technology workers and other employees with years of operational experience in the Group's business. Further workforce reductions are planned and could include key employees with valuable skills and knowledge whose departure would adversely affect the Group's ability to continue to develop new and enhance existing products. At the same time, the uncertainties associated with headcount reductions and the Group's prospects generally may cause key employees to leave and otherwise increase employee and management turnover, which may contribute to and result in inefficiencies in running the Group's business. In addition, following the Restructuring, the incentive arrangements offered by the Group may be perceived as unattractive in comparison with those offered by the Group's competitors, which may make it more difficult to retain personnel and attract qualified replacements for those who leave. The loss of additional key managers and highly skilled technology workers may result in the Group's inability to develop new products on a timely basis, improve current technologies or operate its business efficiently. THE GROUP IS RELIANT ON THE CONTINUED PERFORMANCE OF THIRD PARTIES IN RELATION TO CERTAIN OUTSOURCING ARRANGEMENTS. The Group relies on outsourcing arrangements for the manufacture of certain products and components and is considering further potential outsourcing opportunities in its supply chain and logistics organisation and with respect to information technology. If the third parties on whom the Group relies or will rely in relation to these outsourcing arrangements do not fulfil their obligations under such contracts, or seek to terminate or change the terms of their contracts due to perceived uncertainty with respect to the Group's ongoing ability to perform under such contracts, or if the Group does not otherwise properly manage these relationships, such supplies or services could be severely disrupted or reduced. A significant increase in the price of key supplies or services or constraints on suppliers' capacities, particularly during periods of significant demand, in the absence of an alternative supplier, would adversely affect the Group's business. Moreover, outsourcing initiatives ultimately 179

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- may not yield the benefits the Group expects, and may raise product costs and delay product production and service delivery. The Group's outsourcing arrangements are discussed in Part A.7 of this Section. MEASURES TO REDUCE OPERATING COSTS COULD ADVERSELY AFFECT RELATIONS WITH EMPLOYEES OF THE GROUP, ITS SUPPLIERS AND/OR ITS PARTNERS, WHICH COULD DISRUPT ITS BUSINESS. In order to further reduce operating costs, the Group intends to reduce the size of its workforce, in part through further rationalisation of its activities and outsourcing initiatives, and to seek to renegotiate certain existing contracts with suppliers and partners in order to obtain more favourable terms. The implementation of these plans may increase demands on, and/or negatively impact relations with, employees of the Group and its suppliers and partners. Such negative impact may result in a diminution in employee morale, labour disruptions, industrial action and/or labour-related law suits against the Group, its suppliers or partners. Any of these results could diminish the efficient operation of the Group's business, disrupt services at the facilities of the Group, its suppliers or partners and inhibit the realisation of the operating cost reductions that are fundamental to the Group's financial objectives, which would have a material adverse effect on the Group's business, financial condition and results of operations. In Europe, particularly, employees are protected by laws giving them, through local and central work councils, rights of consultation with respect to specific matters regarding their employers' business and operations, including the downsizing or closure of facilities and employee terminations. These laws, and collective bargaining agreements to which the Group, its suppliers or partners may be subject, could impair the Group's flexibility as it continues to pursue reductions in operating expenses. THE GROUP'S FINANCIAL REPORTING SYSTEMS REQUIRE SIGNIFICANT OPERATIONAL RESOURCES. As a result of the rapid expansion of the Group in 1999 and 2000, the number of different acquired systems, the deferral of the introduction of a Group-wide FRP system due to cost considerations and the disposal of a number of businesses from the Group, the operation of the Group's financial reporting systems has required and will continue to require considerable personnel resources. Taken together with the demands of the Restructuring process, this has placed significant pressure on the resources of the finance function. The Group is also in the process of implementing a number of changes to its consolidation and financial reporting systems, with a view to streamlining the existing reporting processes. Although Corp and plc currently believe that the Group's financial reporting systems are, and without the changes referred to above would remain, fit for purpose, the continued effectiveness of these systems following the Restructuring is dependent on a combination of the continued availability of sufficient finance team resources and any changes that are made to the financial reporting system being successfully implemented. FUNDING OF PENSION PLANS MAY BECOME MORE DIFFICULT. The interaction of poor equity markets and low interest rates over the last several years has had a significant negative impact on the funded status of and liabilities under the Group's defined benefit pension plans and contribution obligations under such plans, more details of which are set out in Part D.11 of this Section. Corp either sponsors such plans or is exposed to liabilities with respect to plans sponsored by affiliates or former affiliates. It is possible that unless equity markets and/or interest rates improve, such obligations may require Corp and/or its affiliate sponsoring companies to such plans to make additional contributions. Likewise, changes in the statement of investment principles of the UK plans, the actuarial assumptions employed in conjunction with any such plans or legislation could also result in a need for Corp and/or its affiliates to make additional contributions to such plans. Corp does not believe that (as at 5 April 2002, the date for when figures are last available) the UK Plan has a funding deficit (by reference to the plan's own on-going basis), however investment conditions have deteriorated since 5 April 2002. If the UK Plan is wound up, however, then it is unlikely that it will have sufficient assets to discharge in full all liabilities, calculated on a winding-up rather than an on-going basis. No plans have been made to wind up the UK Plan but should such a decision be made (as opposed to operating it as a plan closed to new members), Corp and the participating Group Companies would (under current legislation) be required to make good any statutory debt (if there is one). If a statutory debt were to arise, the size of the debt (relative to the 180

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- Group's assets) could have a materially detrimental effect on the Group's resources. The significance of the potential detrimental effect should be seen against Corp's estimate that (as at 5 April 2002) the value of the UK Plan's assets was L2.495 billion and the value of its liabilities was L2.494 billion. There is no guarantee that the value of the UK Plan's assets will not deteriorate nor that legislation will not be introduced to oblige employers to make further contributions to pension plans which are not fully funded on a specified basis which is stricter than that required by current legislation. In its Green Paper published on 17 December 2002, the UK government has said that it is considering replacing the statutory minimum funding requirement with a scheme-specific minimum funding level, which could be higher. Following the sale of General Domestic Appliances Holdings Limited in 2001, the trustee of the UK Plan is expected to make a payment to the buyer's pension plan in respect of the accrued benefits of the employees who transferred to the buyer. Although a basis for calculation of the transfer amount was agreed in the sale agreement for the sale of General Domestic Appliances, the trustee of the UK Plan is not bound by this. Corp is responsible for 50 per cent. of any shortfall between the transfer amount agreed in the sale agreement and the amount actually paid by the trustee. Anticipating a shortfall at the time of the sale, an allowance of L3.255 million was made in the sale price. The information received by Corp to date is that the plan actuary intends to advise the trustee to calculate the transfer amount on a basis which would (apart from the allowance in the sale price) result in a liability for Corp under the shortfall obligation of approximately L1.47 million. Allowing for the price adjustment, Corp would on these figures be entitled to L1.785 million from the buyer. If the trustee does not follow the advice of the actuary or if the actuary changes his advice, Corp expects its maximum liability under the shortfall obligation to be L14.665 million (or L12.88 million if the net over-allowance by Corp is taken into account). The actuary is not bound by his representations and a final determination of the transfer amount is not likely until April or May 2003. There can be no assurance that the trustee will not decide to follow a basis which results in a greater liability for Corp than Corp currently expects or that any such liability would not have a material adverse effect on the Group. Indeed, if the trustee refuses or fails to transfer the whole or any part of the agreed amount, Corp will be liable to pay 50 per cent. of the shortfall (less the buyer's prevailing rate of corporation tax), which could produce a significant larger liability. THERE IS A RISK THAT THIRD PARTY INTELLECTUAL PROPERTY RIGHTS WILL BE ASSERTED AGAINST THE GROUP. The Group relies on patents, trade marks, trade secrets, design rights, copyrights, confidentiality provisions and licensing agreements to establish and protect its proprietary technology and to protect against claims from others. Infringement claims have been and may continue to be asserted against the Group or against its customers in connection with their use of the Group's systems and products. The Group cannot ensure the outcome of any such claims and, should litigation arise, such litigation could be costly and time-consuming to resolve and could result in the suspension of the manufacture of the products utilising the relevant intellectual property. In each case, the Group's operating results and financial condition could be materially affected. F.4 RISKS RELATED TO OWNERSHIP OF THE NEW SHARES, THE NEW NOTES AND THE WARRANTS THERE IS NO CURRENT TRADING MARKET FOR THE NEW SHARES, THE NEW NOTES OR THE WARRANTS, AND THE MARKET PRICES OF THE NEW SHARES, THE NEW NOTES AND THE WARRANTS MAY BE ADVERSELY AFFECTED BY SIGNIFICANT SELLING ACTIVITY IN THE PERIOD FOLLOWING IMPLEMENTATION OF THE RESTRUCTURING. The New Shares, the New Notes and the Warrants comprise new issues of securities for which there is currently no public trading market. There can be no assurance as to the development or liquidity of any market for the New Shares, the New Notes or the Warrants. To the extent that the New Shares and the Warrants are traded after their initial issuance, they may trade at prices that are lower than the initial market values thereof depending on many factors, including prevailing interest rates and the markets for similar securities as well as technological, market, economic, legislative, political, regulatory and other factors. Similarly, the New Notes may, after their initial issuance, trade at a substantial discount to their principal amounts, depending upon prevailing interest rates, the market for similar securities, the performance of Corp and other factors. There can be no assurance that active trading markets will develop or be maintained for the New Shares, the Warrants or the New Notes. Significant sales of the New Shares, the Warrants or the New Notes would be likely to result in a decline in their respective market prices. It is likely that certain persons who receive New Shares or Warrants through the 181

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- Schemes will sell the New Shares or the Warrants they receive very soon after the Corp Scheme becomes effective and those securities are initially issued. These sales could result in significant downward pressure on the market price of the New Shares or the Warrants. Similar sales and corresponding price pressure could also affect the New Notes. CORP WILL BE DEPENDENT IN PART ON FUNDS RECEIVED FROM ITS SUBSIDIARIES TO PAY INTEREST AND PRINCIPAL ON THE NEW NOTES AND TO PAY DIVIDENDS, IF ANY, ON THE NEW SHARES. Corp is a holding company, its principal assets being its investments in its subsidiaries. As a holding company, Corp's ability to pay dividends on the New Shares and to pay interest and principal on the New Notes is dependent upon the receipt of funds from its subsidiaries by means of dividends, interest, inter-company loans or otherwise. The ability of its subsidiaries to make funds available to Corp is subject, among other things, to applicable corporate and other laws and restrictions contained in agreements to which such subsidiaries are subject. There can be no assurance that Corp's subsidiaries will be in a position to make funds available. Any limitations on the ability of its subsidiaries to make funds available to Corp would have a corresponding adverse effect on Corp's ability to make payments of interest and principal on the New Notes and to pay dividends, if any, on the New Shares. In addition, the terms of the indentures governing the New Notes will significantly restrict the ability of Corp to pay dividends on Corp Shares while the New Notes are outstanding. Accordingly, Corp does not expect to pay dividends on Corp Shares for the foreseeable future. THE US RINGFENCING WILL GIVE RISE TO OPERATIONAL AND FINANCIAL INEFFICIENCIES AND OTHER COSTS WHICH MAY ADVERSELY AFFECT THE GROUP'S BUSINESS AND THE MARKET PRICE OF THE NEW SHARES. As described in Part A.2 of this Section certain of the Group's US businesses will be contractually separated or "ringfenced" from the rest of the Group upon implementation of the Restructuring. This US Ringfencing may have significant implications for holders of New Notes, as well as holders of New Shares. The covenants in the indentures governing the New Notes will regulate the type of financial, operational and other dealings that the Non-Ringfenced Entities can have with the Ringfenced Entities. The covenants in the New Notes will also require Corp to separate the North American Access Business, BBRS Business and OPP Business into separate subsidiaries within the US Ringfencing no later than the second anniversary of the issue date of the New Notes. Moreover, the Non-Ringfenced Entities will generally be prohibited from providing funding for any of the Ringfenced Entities and, following the separation of the three principal businesses within the US Ringfencing, the North American Access Business, BBRS Business and OPP Business will generally be prohibited from providing funding to each other. The Ringfenced Entities will enter into various agreements with the Non-Ringfenced Entities necessary to ensure that from the Effective Date those dealings that are permitted with each other will be provided in the ordinary course of business on an arm's-length basis or otherwise as permitted by the covenants in the indentures governing the New Notes. These arrangements for the provision of such services may lead to higher costs for the Group as a whole which may affect its results of operations, as well as Corp's ability to repay the New Notes. In addition to the foregoing, the operational and financial inefficiencies and other costs associated with the US Ringfencing arrangements could have an adverse effect on Corp's business and on the market price of the New Shares. CORP MAY BE UNABLE TO REPAY THE NEW NOTES AT MATURITY. Corp currently intends to repay any principal amount outstanding in respect of the New Notes at their maturity in part from cash generated by the Group. As discussed above, the Group currently is cash flow negative and its ability to generate significant positive cash flow in the future is subject to significant risks and uncertainties. If the Group is unable to generate sufficient cash to allow Corp to repay the New Notes at maturity, Corp would need to obtain other financing for this purpose. However, also as discussed above, Corp's ability to obtain such financing may be extremely limited. Accordingly, no assurance can be given that Corp will be able to repay any of the New Notes at their maturity. 182

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- In the event that Corp is unable to repay the New Notes following an event of default or at their maturity (either from its own cash or from other sources of funding), no assurances can be given as to whether the proceeds of the security granted by Corp and the Guarantors in connection with the New Notes will be sufficient to meet any shortfall. Whilst the holders of the New Notes will have the benefit of the Security (as described in Appendix 10), such security: a. ranks in its entirety behind the security in favour of the providers of the Performance Bonding Facility; b. ranks behind certain cash collateral in favour of the providers of existing performance bonds; and c. in relation to the property located at Warrendale Pennsylvania, ranks behind the first mortgage in favour of Liberty Funding L.L.C. as provider of the Working Capital Facility to be made available to Marconi Communications, Inc. THE NEW NOTES ARE SUBJECT TO A REDEMPTION OBLIGATION AT A PREMIUM UPON A CHANGE OF CONTROL OF CORP WHICH MAY DISCOURAGE POTENTIAL BIDDERS. Upon the occurrence of specific kinds of change of control or merger events, Corp will be required to offer to repurchase all outstanding New Notes at the greater of 110 per cent. of their aggregate principal amount or a make whole amount based on 50 basis points above the yield on US treasuries of similar maturity plus, in each case accrued and unpaid interest. This obligation to redeem the New Notes at a premium could have the effect of deterring third parties who might otherwise offer to acquire a controlling interest in the Group or could adversely affect the terms on which any such offer is made. This redemption obligation may accordingly have an adverse effect on the market price of the New Shares and could deprive holders of the New Shares of an opportunity to receive a premium for their New Shares upon a change of control of the Group. THE FUNDING STATUS OF THE GROUP'S US PENSION PLANS AND THE AGREEMENT ENTERED INTO BY CORP WITH THE PBGC WITH RESPECT TO THOSE PLANS COULD DELAY OR ADVERSELY AFFECT THE TERMS OF THE SALE OF THE GROUP'S US BUSINESSES. As described in Part D.11 of this Section, the funding status of certain tax-qualified defined benefit plans subject to the regulation of the Pension Benefit Guaranty Corporation ("PBGC") in the United States could result in action being taken by the PBGC that might delay or otherwise adversely affect the sale of the Group's US Businesses or assets used therein (or the net proceeds realised therefrom). The likelihood of such action will depend in part on the funded status of such plans at the time of any such sale, the creditworthiness of the purchaser following such sale and the extent to which the pension liabilities are assumed by the purchaser in any such sale. Although Corp has entered into a memorandum of understanding with the PBGC with a view to making such adverse action less likely, under this memorandum of understanding specified conditions must be satisfied in connection with any such sale. To the extent that these matters give rise to any delay or other adverse consequences with respect to the sale of the Group's US Businesses, holders of New Shares and New Notes, and in particular holders of New Junior Notes, could be adversely affected. IT IS UNLIKELY THAT CORP WILL PAY DIVIDENDS FOR THE FORESEEABLE FUTURE. Corp does not anticipate paying dividends on the New Shares in the foreseeable future. Moreover, even if Corp has distributable reserves and becomes cash flow positive and profitable and so is in a position to pay dividends, the indentures relating to the Notes significantly restrict its ability to pay dividends. Certain institutional investors may only invest in dividend-paying equity securities or may operate under other restrictions that may prohibit or limit their ability to invest in the New Shares. This may reduce the demand for the New Shares until Corp is able to pay dividends in respect of the New Shares, which may in turn adversely affect the price of the New Shares in the market. 183

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- PRE-EMPTIVE RIGHTS FOR NON-UK HOLDERS OF NEW SHARES MAY NOT BE AVAILABLE. In the case of, amongst other things, an increase of the share capital of Corp, existing shareholders are entitled to pre-emptive rights pursuant to the Act and Corp's articles of association unless waived by a resolution of the shareholders at a general meeting or in the circumstances stated in Corp's articles of association. Even where pre-emptive rights apply, holders of the New Shares in the United States, South Africa, Australia, Canada and other jurisdictions outside the United Kingdom may in practice not be able to exercise pre-emptive rights in respect of their New Shares unless Corp decides to comply with applicable local laws and regulations and, in the case of holders of the New Shares in the United States, a registration statement under the US Securities Act is effective with respect to such rights, or an exemption from the registration requirements thereunder is available. Corp intends to evaluate at the time of any pre-emptive rights offering the costs and potential liabilities associated with any such registration statement and compliance with other applicable local laws and regulations, as well as the indirect benefits to it of thereby enabling or facilitating the exercise by holders of the New Shares in the United States and such other jurisdictions of their pre-emptive rights for new securities in respect of their New Shares and any other factors Corp considers appropriate at the time, and then to make a decision as to how to proceed and whether to file such a registration statement or comply with such other applicable local laws and regulations. No assurance can be given that any registration statement with respect to the securities offered under a pre- emptive issue would be filed or any such other local laws and regulations would be complied with to enable the exercise of such holders' pre-emptive rights. IN THE EVENT OF ENFORCEMENT OF THE SECURITY FOR THE NEW NOTES AND THE PERFORMANCE BONDING FACILITY, THE NEW NOTES WILL RANK JUNIOR IN RIGHT OF PAYMENT TO THE PERFORMANCE BONDING FACILITY, THE NEW JUNIOR NOTES WILL RANK JUNIOR IN RIGHT OF PAYMENT TO THE NEW SENIOR NOTES, AND THE RIGHTS OF THE NEW JUNIOR NOTES TO TAKE ENFORCEMENT ACTION WITH RESPECT TO THE SECURITY WILL BE LIMITED. Corp, the Guarantors, the indenture trustees for the New Notes and the agent under the Performance Bonding Facility, among others, will enter into a Security Trust and Intercreditor Deed that will establish the relative priorities among the New Senior Notes, the New Junior Notes and the Performance Bonding Facility in the event of enforcement of the security therefor. Following the occurrence of a payment default and/or an acceleration of the maturity of the New Senior Notes, all proceeds from enforcement of the security granted by Corp and the Guarantors to secure their respective obligations under the New Notes, the guarantees thereof and the Performance Bonding Facility will be applied as follows: - first, to the fees and expenses of the trustees and other agents; - second, to the banks providing the Performance Bonding Facility; - third, to repayment of the New Senior Notes; and - fourth, to repayment of the New Junior Notes. Under the terms of the Security Trust and Intercreditor Deed, no payments may be made on the New Junior Notes (other than payments of interest in kind) and no redemptions of the New Junior Notes from the proceeds of asset sales may be made, subject to limited exceptions: (i) following a payment default under, or acceleration of, the New Senior Notes until the payment default or acceleration has been remedied or waived or unless at least a majority in principal amount of the New Senior Notes consent in writing or all liabilities arising under the New Senior Notes are paid in full, or (ii) following a standstill notice being delivered by the New Senior Notes Trustee to the Security Trustee (notifying it of the occurrence of a default under the New Senior Notes) for a period of up to 179 days. In addition, under the terms of the Security Trust and Intercreditor Deed, the holders of the New Junior Notes may not: - accelerate the New Junior Notes during a standstill period (as described in more detail in Part C of this Section); - take enforcement action against any security securing the New Junior Notes without the consent of the holders of the New Senior Notes or unless all liabilities arising under the New Senior Notes have been discharged in full; or 184

I. EXPLANATORY STATEMENT (IN COMPLIANCE WITH SECTION 426 OF THE COMPANIES ACT 1985) SECTION 2: FURTHER EXPLANATION OF THE RESTRUCTURING -- PART F -------------------------------------------------------------------------------- - amend the indenture for the New Junior Notes, with limited exceptions. Furthermore, if the holders of the New Senior Notes agree to waive a default or event of default and/or amend the New Senior Notes or the related indenture to address the circumstances leading to such default or event of default, the holders of the New Junior Notes will be deemed to have waived such default or event of default and/or the corresponding provisions of the New Junior Notes and the related indenture will be amended or supplemented to the same effect, in each case without the consent of any holder of New Junior Notes (but subject to certain limitations). THE VALUE OF THE GUARANTEES AND THE COLLATERAL MAY BE LIMITED BY APPLICABLE LAWS. Corp's obligations under the New Notes and the Performance Bonding Facility will be guaranteed by certain of Corp's subsidiaries that, with limited exceptions, must include on an ongoing basis (i) subsidiaries that together account for at least 80 per cent., and (ii) each subsidiary that individually accounts for more than 5 per cent, in each case, of the total assets, total external assets, total external sales, and (commencing as of 31 March 2005) total EBITDA of Corp and its subsidiaries. Corp and the Guarantors will, with limited exceptions, grant security over substantially all of their respective assets to secure their respective obligations under the New Notes and the guarantees as well as the Performance Bonding Facility. The obligations of the Guarantors will be limited under the relevant laws applicable to such Guarantors and the granting of such guarantees and/or security (including laws relating to corporate benefit, capital preservation, financial assistance, fraudulent conveyances, fraudulent transfers or transactions at an under value) to the maximum amount payable or secured such that such Guarantees or security will not constitute a fraudulent conveyance, fraudulent transfer or a transaction at an under value, or otherwise cause the Guarantor to be insolvent under relevant law or such guarantees or security to be void or unenforceable or cause the directors of such Guarantor to be held in breach of applicable corporate or commercial law for providing such Guarantee or security. As a result, a Guarantor's liability under its guarantee and/or the value of security granted could be reduced to zero. Notwithstanding the foregoing limitations to the guarantees, there can be no assurance that the provision of any guarantee by any particular Guarantor or Guarantors will not be challenged by a liquidator, administrator or other creditor of such Guarantor or Guarantors. If a court voided any guarantee or held it unenforceable, holders of New Notes would cease to have a claim in respect of the guarantee by the relevant Guarantor and, accordingly, would cease to be a creditor of such Guarantor. 185

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART II THE SCHEME APPLICATION AND EFFECTIVENESS OF THE SCHEME 1. (1) The compromise and arrangement effected by the Scheme shall apply to all Scheme Claims and shall be binding on all Scheme Creditors. (2) For the avoidance of doubt, the Scheme is not conditional upon the plc Scheme becoming effective. (3) The Scheme shall become effective at the Effective Time. STAY OF PROHIBITED PROCEEDINGS 2. (1) Subject to sub-clause 2(2), no Scheme Creditor shall commence or continue any Prohibited Proceeding in respect of, arising from, or relating to, a Scheme Claim after the Effective Time. (2) Nothing in this Scheme shall prevent: (a) a landlord of leasehold property of the Company from exercising such rights and remedies of distress, forfeiture and re-entry (and any other of such landlord's self-help rights and remedies) as it may have in respect of such leasehold property; or (b) a secured creditor from exercising its rights and remedies as a secured creditor in respect of any Property of the Company. 3. Subject to sub-clause 20(2), a Scheme Creditor may commence or continue an Allowed Proceeding against the Company after the Effective Time provided that it has first: (1) where the Scheme Creditor is continuing an Allowed Proceeding, notified the Supervisors in writing of its intention to do so; (2) where the Scheme Creditor intends to commence an Allowed Proceeding, given the Supervisors five Business Days' prior notice in writing of its intention to do so; and (3) where sub-clause 17(2) applies with respect to an Allowed Proceeding, it has, in addition to complying with sub-clause 3(1) or 3(2) as applicable, complied with that sub-clause. 4. (1) Save in respect of any Allowed Proceeding as permitted by this Scheme or any action permitted under sub-clause 2(2), each Scheme Creditor by this Scheme covenants not to sue the Company in respect of a Scheme Claim. (2) For the purpose of enforcing the covenant in sub-clause 4(1), the Company is hereby appointed as the agent and attorney of each and every Scheme Creditor for the purpose of giving any and all instructions (and doing any such acts or things) as are necessary or desirable to enforce that covenant. 5. If any Scheme Creditor commences or continues any such Prohibited Proceeding as is prohibited by sub-clause 2(1) after the Effective Time it shall be treated as having received, on account of its entitlement to Scheme Consideration, an advance payment by way of a Distribution equal to the amount or gross value of any money, property, benefit or advantage obtained by it after the Effective Date at the expense of the Company or, as applicable, as a result, directly or indirectly, of such Prohibited Proceeding, and the extent, if any, to which it is entitled to Scheme Consideration shall be reduced accordingly. Such Scheme Creditor shall hold any benefit received or receivable in excess of its entitlement to Scheme Consideration pursuant to the terms of the Scheme as a result, directly or indirectly, of a Prohibited Proceeding on trust for the Company and shall account to the Company for such excess benefit. For this purpose, the gross value of any such property, benefit or advantage shall be conclusively determined by the Supervisors and may include such amount as the Supervisors may consider to be appropriate by way of interest or costs, charges or expenses incurred by the Company and/or the Supervisors as the result of such Prohibited 202

II. THE CORP SCHEME -------------------------------------------------------------------------------- Proceeding. This treatment and reduction is without prejudice to the Company's rights first to any injunctive or other relief or remedy to which the Company may be entitled in respect of the breach and, secondly, in respect of any loss the Company may suffer as a result of the breach. The Supervisors shall make such consequential adjustments to the amount and timing of payment of Distributions to any such Scheme Creditor (and in the case of Definitive Holders, to the Eurobond Trustee or the Yankee Bond Trustee or both as appropriate) pursuant to the rules and formulae in Part III as are necessary to give effect to this clause. ASSIGNMENTS OR TRANSFERS 6. (1) The Supervisors shall be under no obligation to recognise any assignment or transfer of Scheme Claims after the Record Date for the purposes of determining entitlements under the Scheme, provided that where the Supervisors have received from the relevant parties notice in writing of such assignment or transfer, the Supervisors may, in their sole discretion and subject to the production of such other evidence as they may require and to any other terms and conditions which they may consider necessary or desirable, agree to recognise such assignment or transfer for the purposes of determining entitlements under the Scheme. Any assignee or transferee of a Scheme Claim so recognised by the Supervisors shall be bound by the terms of this Scheme and for the purposes of this Scheme shall be a Scheme Creditor. (2) For the purposes of the Scheme (including for the purposes of the definition of Excluded Claims) no recognition shall be given to any assignment or transfer of any (or any part of any) debt, claim or right of any person in respect of a Liability of the Company effected between 1 January 2003 and the Record Date (both dates inclusive) other than any such assignment or transfer pursuant to or contemplated by the Scheme Implementation Deed if, in the reasonable opinion of the Supervisors, a material purpose of such assignment or transfer was to make such debt, claim or right (or part thereof) an Excluded Claim (under sub-paragraph 13 of the definition of Excluded Claims) and not a Scheme Claim. (3) For the avoidance of doubt, in relation to the Bonds, Bondholders are permitted to assign or transfer their interest in Bonds after the Record Date. EFFECT OF SCHEME 7. (1) This clause is without prejudice to the Company's rights under clauses 2 and 5 and is subject to Part X. (2) Without prejudice to clause 20, in consideration of the rights of Scheme Creditors under this Scheme (including the rights of Admitted Scheme Creditors to receive Scheme Consideration), all Liabilities on the part of the Company in respect of each Scheme Claim (and any interest accruing thereon or other amounts payable in connection therewith whether arising before or after the Record Date), automatically and without further documentation or action of the parties, shall be compromised, fully and finally discharged, satisfied and cancelled on the earlier of: (a) the first date on which such Scheme Claim is both Admitted and the subject of a Distribution Notice; (b) the Final Distribution Date; and (c) the issue of the Termination Notice (other than a Termination Notice served pursuant to sub-clause 115(3)). (3) No Scheme Claim of a Scheme Creditor shall be reduced or in any way affected by the compromise of any claims of that Scheme Creditor against plc pursuant to the terms of the plc Scheme nor shall it be reduced or in any way affected by reason of any distributions received by or on behalf of that Scheme Creditor in the plc Scheme provided that the aggregate recoveries of a Scheme Creditor in respect of a claim pursuant to the Scheme and the plc Scheme shall not exceed the quantum of the Scheme Claim. 203

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART III DETERMINATION OF SCHEME CLAIMS AND PROCEDURE FOR DISTRIBUTIONS RECORD DATE 8. (1) All Scheme Claims shall be determined as at the Record Date. (2) Any Scheme Claim which at the Record Date is not immediately due and payable but on the Company going into insolvent liquidation would, either automatically without further action by any party or by the issue of a notice by the relevant Scheme Creditor, be capable of being made legally and immediately due and payable shall be treated for the purposes of Distributions under this Scheme as immediately due and payable as at the Record Date (and hence not a debt payable at a future time). RULES AND PROCEDURES 9. The Supervisors shall consider each Claim Form submitted to determine the existence and quantum of each Submitted Scheme Claim and shall decide the extent, if any, to which it shall be Admitted in accordance with the rules and procedures set out in the Scheme and in particular in Schedule 1. ONLY ADMISSIBLE INTEREST 10. Without prejudice to sub-clause 7(2), for the purpose solely of the determination and payment of Distributions under the Scheme, no Admitted Scheme Claim shall include any amounts in respect of interest except Admissible Interest and, for the avoidance of doubt, any interest other than Admissible Interest shall not be taken into account by the Supervisors in determining the quantum of the relevant Scheme Claim. NO ADMISSIONS OF LIABILITY 11. Save as expressly set out in this Scheme or the Explanatory Statement, nothing in the Scheme or the Explanatory Statement or the distribution thereof to any person evidences or constitutes any admission by the Company, the Prospective Supervisors, the Supervisors or KPMG that a person is a Scheme Creditor or that a Liability is owed to any person in respect of any claim or right. The failure to distribute the Scheme, Explanatory Statement, any notice or any other communication to any Scheme Creditor shall not constitute an admission by the Company, the Prospective Supervisors, the Supervisors or KPMG that such person is not a Scheme Creditor or that any Liability owed to such person is an Excluded Claim. PROVISION OF INFORMATION 12. (1) A Scheme Creditor submitting a Scheme Claim: (a) shall provide the Supervisors with such information as they may reasonably require to enable the claim to be determined (and for the avoidance of doubt shall comply with such of the rules and procedures in Schedule 1 as the Supervisors may require); and (b) shall, in any event, submit a Claim Form to the Prospective Supervisors or, after the Effective Date, to the Supervisors (in accordance with the instructions set out in the Claim Form) at the relevant address set out in the Claim Form by hand or by Post. (2) Scheme Creditors who wish an Initial Distribution to be distributed to the Eligible Recipient in respect of that Scheme Creditor's Scheme Claim on the Effective Date must have submitted their duly completed Claim Forms so as to be received by the Prospective Supervisors by 5.00 p.m. (London time) on the First Claim Date. Only Known Creditors that have complied with this precondition and whose Scheme Claims are listed in the First Initial Distribution Notice shall be Admitted by the Supervisors in accordance with the Scheme on the Effective Date and participate in the First Initial Distribution in accordance with clause 23. Only if a Scheme Creditor has 204

II. THE CORP SCHEME -------------------------------------------------------------------------------- complied with this pre-condition and its Scheme Claim is Admitted by the Supervisors in accordance with the Scheme on the Effective Date shall that Admitted Scheme Creditor's Eligible Recipient receive an Initial Distribution when the First Initial Distribution is made. (3) For the purposes of this Scheme, it is expressly recognised that: (a) the Eurobond Trustee shall be entitled to submit a Claim Form in its capacity as creditor under the Trust Deeds in respect of all of the Eurobonds and, in consequence, no person with an interest in the Eurobonds other than the Eurobond Trustee shall be entitled to submit a Claim Form in respect of the Eurobonds by virtue of such interest; and (b) the Yankee Bond Trustee shall be entitled to submit a Claim Form in accordance with section 5.04 of the Indenture and, in consequence, no person with an interest in a Yankee Bond other than the Yankee Bond Trustee shall be entitled to submit a Claim Form in respect of the Yankee Bonds by virtue of such interest. ENTITLEMENT TO SCHEME CONSIDERATION 13. Eligible Recipients shall be eligible to receive Scheme Consideration in accordance with the Scheme. A Scheme Creditor with a Scheme Claim which is Unadmitted shall not be entitled to Scheme Consideration in accordance with the Scheme unless, until and to the extent that such Scheme Claim becomes Admitted. 14. The amount of the Scheme Consideration to which a Scheme Creditor is entitled (and any Eligible Recipient in respect of that Scheme Creditor's Admitted Scheme Claim is eligible to receive) shall be calculated in accordance with this Part III. ADMISSION AND REJECTION OF SCHEME CLAIMS 15. A Scheme Claim may be Admitted by the Supervisors either for the whole amount claimed by the Scheme Creditor or for part of that amount. 16. If the Supervisors refuse to admit a Scheme Claim, in whole or in part, they shall promptly prepare a written statement of their reasons for doing so, and send it to the Scheme Creditor, accompanied by a notice of rejection in such form as the Supervisors shall determine. APPEAL AGAINST DECISION ON SCHEME CLAIMS 17. (1) If a Scheme Creditor is dissatisfied with a refusal by the Supervisors to admit, in whole or in part, a Scheme Claim then, subject to sub-clause 17(2), it may either commence or continue an Allowed Proceeding to determine the existence and/or quantum of its Scheme Claim or elect by notice in writing to the Supervisors that the existence or quantum of its Scheme Claim be referred for adjudication in accordance with Part VI. (2) If an Allowed Proceeding has not been commenced, or is not being continued as at the date of the notice of rejection, then either: (a) an Allowed Proceeding must be commenced (and notice given in accordance with clause 3); or (b) an election for adjudication made in accordance with sub-clause 17(1) by the Scheme Creditor, in each case within 40 Business Days following receipt by the Scheme Creditor of the notice of rejection. 18. If a Scheme Claim has not been Admitted and at the expiration of the 40 Business Days period referred to in sub-clause 17(2) an Allowed Proceeding is continuing (whether commenced by the Scheme Creditor before or after receipt of the notice of rejection) or an election has been made for adjudication (in each case in accordance with clause 17) then: 205

II. THE CORP SCHEME -------------------------------------------------------------------------------- (1) any final determination of that Allowed Proceeding (after the ordinary time for appealing the original determination or any determination on appeal has expired without any appeal having been made) shall be binding on the Scheme Creditor, the Company and the Supervisors; (2) if an election has been made for adjudication the provisions of Part VI shall apply; and (3) without prejudice to sub-clauses 18(1) and 18(2), the Scheme Creditor and the Supervisors may at any time agree to any matter or issue in the Allowed Proceeding being determined in some manner other than in the Allowed Proceeding, and any Proceeding commenced pursuant to such agreement shall have effect as an Allowed Proceeding commenced in accordance with clause 17. 19. If in an Allowed Proceeding or in an adjudication pursuant to Part VI any order or direction shall be made that any costs of such proceeding or adjudication are to be borne by the Supervisors or by the Company, such costs shall be payable in full by the Company. 20. If a Scheme Claim has not been Admitted and at the expiration of the 40 Business Days period referred to in sub-clause 17(2) neither an Allowed Proceeding (in accordance with the terms of the Scheme) is continuing in respect of such Scheme Claim nor an election (in accordance with the terms of the Scheme) has been made for that Scheme Claim to be referred to adjudication in accordance with Part VI, then: (1) the Company shall be released from all Liabilities in relation to the Scheme Claim (or part thereof) which has not been Admitted (and any interest accruing thereon or other amounts payable in connection therewith whether arising before or after the Record Date); and (2) any Proceeding which is thereafter commenced and which would otherwise have been an Allowed Proceeding shall be a Prohibited Proceeding. THE BASIC SCHEME CONSIDERATION, THE KNOWN CLAIMS SEGMENT AND THE RESERVE CLAIMS SEGMENT 21. (1) The Basic Scheme Consideration is: (a) cash of L340,000,000 or such larger sum of cash calculated in accordance with sub-clause 21(2); (b) the euro equivalent (applying the Currency Rate) of L450,000,000 New Senior Notes to be issued in both or either euro and US dollars, subject to elections by Scheme Creditors and Bondholders described in Recital J; (c) an aggregate of US$300,000,000 and the US dollar equivalent (applying the Currency Rate) of L117,270,000 New Junior Notes (or such smaller principal amount of New Junior Notes calculated in accordance with sub-clause 21(2) if the amount of Cash is increased); and (d) 995,000,000 New Creditor Shares. (2) If there is any Excess Cash, the amount of Cash comprising the Basic Scheme Consideration shall be increased by the amount of such Excess Cash, converted into sterling applying the Exchange Rate on the date such cash is first received by the Company or the Subsidiary, as the case may be. Following 1 May 2003 but prior to the Effective Date, the aggregate principal amount of the New Junior Notes shall be decreased by 10/11ths of the sterling amount by which the Cash has been so increased (such calculation to reduce the L117,270,000 figure referred to in sub-clause 21(1)(c)). (3) In this Scheme: (a) the term "BASIC KNOWN CLAIMS SEGMENT" means that part of the Basic Scheme Consideration calculated by applying the fraction: <Table> <S> <C> KC ---------------- 125,000,000 + KC </Table> 206

II. THE CORP SCHEME -------------------------------------------------------------------------------- to each Element of Basic Scheme Consideration, where KC = the aggregate amount of the Known Claims; and (b) the term "BASIC RESERVE CLAIMS SEGMENT" means that part of the Basic Scheme Consideration calculated by applying the fraction: 125,000,000 ---------------- 125,000,000 + KC to each Element of Basic Scheme Consideration, where KC = the aggregate amount of the Known Claims. (4) In the Scheme: (a) the term "KNOWN CLAIMS SEGMENT" means that part of the Scheme Consideration available until the expiry or termination of the Waiting Period from which Distributions of Distribution Entitlements of Admitted Known Creditors shall be made being, from time to time, the aggregate of the following: (i) the Basic Known Claims Segment; (ii) any Known Claims Supplement arising under sub-clause 27(3) (or equivalent supplement pursuant to sub-clause 27(5)); (iii) any plc Receipts made available to Known Creditors as a result of the operation of clause 28; and (iv) any Known Rejected Claim Supplement made available to Known Creditors as a result of the operation of clause 29. The parts of the Known Claims Segments listed in (ii) - (iv) above shall be treated for all purposes as a supplement to the Basic Known Claims Segment. Any entitlement to receive a distribution from the Basic Known Claims Segment shall be supplemented by an entitlement to receive a distribution of those other parts (if any) of the Known Claims Segment of the same proportion as the Distribution Entitlement of the relevant Scheme Creditor to the Basic Known Claims Segment is of the Basic Known Claims Segment (but such proportion shall be calculated after taking into account any decrease in the size of the Basic Known Claims Segment resulting from: (A) Known Claims being Conclusively Rejected resulting in a Rejected Claims Supplement being deducted from the Basic Known Claims Segment pursuant to sub-clause 29(1)(a) and becoming available for distribution to Scheme Creditors in accordance with sub-clause 29(2); and/or (B) Known Claims being Conclusively Rejected resulting in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)). (b) the term "RESERVE CLAIMS SEGMENT" means that part of the Scheme Consideration available until the expiry or termination of the Waiting Period from which Distributions of Distribution Entitlements of Admitted Reserve Creditors shall be made being, from time to time, the aggregate of the following: (i) the Basic Reserve Claims Segment; (ii) any Reserve Claims Supplement arising under sub-clause 27(3) (or equivalent supplement pursuant to sub-clause 27(5)); 207

II. THE CORP SCHEME -------------------------------------------------------------------------------- (iii) any plc Receipts made available to Reserve Creditors as a result of the operation of clause 28; and (iv) any Reserve Rejected Claim Supplement made available to Reserve Creditors as a result of the operation of clause 29. The parts of the Reserve Claims Segment listed in (ii) - (iv) above shall be treated for all purposes as a supplement to the Basic Reserve Claims Segment and any entitlement to receive a distribution from the Basic Reserve Claims Segment shall be supplemented by an entitlement to receive a distribution of those other parts (if any) of the Reserve Claims Segment of the same proportion as the Distribution Entitlement of the relevant Scheme Creditor to the Basic Reserve Claims Segment is of the Basic Reserve Claims Segment (but such proportion shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected which results in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)). 22. If a Known Claim is Admitted at a value higher than the value of that Known Claim set out in Schedule 3, the excess over the value set out in Schedule 3 shall be treated as an Admitted Reserve Claim. INITIAL DISTRIBUTION AND FIRST INITIAL DISTRIBUTION 23. (1) Each Scheme Creditor who has a Submitted Scheme Claim which is Admitted before the expiry or termination of the Waiting Period shall be entitled to receive an Initial Distribution from: (a) the Known Claims Segment if its Admitted Scheme Claim is a Known Claim; or (b) the Reserve Claims Segment if its Admitted Scheme Claim is a Reserve Claim. (2) The Supervisors shall use reasonable endeavours to determine promptly whether or not a Submitted Scheme Claim shall be Admitted and, if they do so determine, shall promptly Admit that Submitted Scheme Claim. (3) As soon as reasonably practicable after a Scheme Claim has been Admitted it shall be the subject of a Distribution Notice. (4) On the Effective Date: (a) Known Creditors whose Scheme Claims are Submitted on or before 5.00 p.m. (London time) on the First Claim Date and which have been listed in the First Initial Distribution Notice shall be Admitted by the Supervisors; (b) the Supervisors shall issue the First Initial Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent); (c) Scheme Creditors whose Scheme Claims are Submitted on or before 5.00 p.m. (London time) on the First Claim Date which are Admitted by the Supervisors on the Effective Date but which were not listed in the First Initial Distribution Notice shall be the subject of a Distribution Notice issued by the Supervisors to the Escrow Trustee (with a copy to the Distribution Agent) at the same time as the First Initial Distribution Notice; and (d) Scheme Creditors with Admitted Scheme Claims listed in the First Initial Distribution Notice or in any Distribution Notice issued pursuant to sub-clause 23(4)(c) shall be entitled to an Initial Distribution forthwith upon the issue of the First Initial Distribution Notice (and any Distribution Notice issued pursuant to sub-clause 23(4)(c)) in respect of such Admitted Scheme Claim and its Initial Distribution shall be made to its Eligible Recipient. 208

II. THE CORP SCHEME -------------------------------------------------------------------------------- (5) Scheme Creditors whose Scheme Claims are Submitted and which are Admitted before the expiry or termination of the Waiting Period but in respect of which a First Initial Distribution pursuant to sub-clause 23(4)(b) or an Initial Distribution pursuant to sub-clause 23(4)(c), is not made shall be entitled to an Initial Distribution in respect of such Admitted Scheme Claims and such distributions shall be made to their Eligible Recipients as soon as practicable after such claims have been Admitted. (6) The amount of the Initial Distribution (including, for the avoidance of doubt, the First Initial Distribution) from the Known Claims Segment to which an Admitted Known Creditor is entitled shall be calculated in accordance with the following formula: <Table> <S> <C> <C> KDE = AKC X KCS --- KC </Table> <Table> <S> <C> <C> where KDE = the Distribution Entitlement of the relevant Admitted Known Creditor to each of the Elements of the Basic Scheme Consideration in the Initial Distribution; AKC = the Admitted Known Claim of the relevant Admitted Known Creditor; KC = the aggregate amount of the Known Claims; and KCS = separately, the amount of each of the Elements of the Basic Scheme Consideration comprising the Basic Known Claims Segment as at the Effective Time. </Table> (7) The amount of the Initial Distribution from the Reserve Claims Segment to which an Admitted Reserve Creditor is entitled shall be calculated in accordance with the following formula: <Table> <S> <C> <C> RDE = ARC X KCS --- KC </Table> <Table> <S> <C> <C> where RDE = the Distribution Entitlement of the relevant Admitted Reserve Creditor to each of the Elements of the Basic Scheme Consideration in the Initial Distribution; ARC = the Admitted Reserve Claim of the relevant Admitted Reserve Creditor; KC = the aggregate amount of the Known Claims; and KCS = separately, the amount of each of the Elements of Basic Scheme Consideration comprising the Basic Known Claims Segment as at the Effective Time. </Table> (8) Any Distribution Notice given by the Supervisors to the Escrow Trustee (with a copy to the Distribution Agent) shall instruct the Escrow Trustee to direct the Distribution Agent to make a Distribution to all relevant Eligible Recipients referred to in the Distribution Notice in accordance with the terms of the Scheme. (9) Where in sub-clauses 21(3), 23(6), and 23(7) above any sum included in any of the terms AKC, KC and ARC is in a currency other than sterling then, for the purposes of calculating the relevant fraction, that sum shall be converted to sterling at the Scheme Rate. (10) In the case of a Scheme Claim in respect of Bonds which is Admitted where the aggregate total of all Distributions to Designated Recipients in respect of that claim is less than the Distribution to which the Eurobond Trustee or the Yankee Bond Trustee as appropriate in respect of that claim is entitled, the remainder of the Scheme Consideration shall be held by the Escrow Trustee and dealt with in accordance with the Escrow and Distribution Agreement. TERMINATION OF THE WAITING PERIOD 24. (1) Subject to sub-clause 24(2), if at any time after the issue of the First Initial Distribution Notice the Supervisors are not satisfied that the Reserve Claims Segment is sufficient to make Distributions of 209

II. THE CORP SCHEME -------------------------------------------------------------------------------- Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted, the following shall apply: (a) the Supervisors shall forthwith notify the Company and the Creditors' Committee; (b) the Waiting Period shall terminate and all entitlements of Admitted Scheme Creditors to Scheme Consideration which have not been the subject of a Distribution Notice shall be dealt with in accordance with the provisions of clause 25; and (c) for the avoidance of doubt, the provisions of this clause shall not affect the Distribution Entitlement of any Scheme Creditor whose Admitted Scheme Claim is the subject of a Distribution Notice issued prior to the issue of the Supervisors' notice in sub-clause 24(1)(a). (2) If a Scheme Claim is Submitted after the issue of the First Initial Distribution Notice which: (a) if immediately Admitted would result in the Supervisors not being satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted; and (b) the Supervisors cannot immediately determine whether, or the extent to which, that Submitted Scheme Claim should be Admitted, the Supervisors may consider that Scheme Claim for a period of up to 30 Business Days from the date on which that Scheme Claim is Submitted (the "EXAMINATION PERIOD"). The Supervisors shall forthwith notify the Company and the Creditors' Committee of the commencement of the Examination Period. On, or prior to, the expiry of such 30 Business Days the Supervisors shall confirm to the Creditors' Committee and the Company whether or not they are satisfied that the Reserve Claims Segment shall be sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted. The issue of the Supervisors' confirmation or, if later, the expiry of the 30 Business Day period shall bring the relevant Examination Period to an end. If no confirmation is provided prior to the expiry of such 30 Business Days, the Supervisors are deemed to be not satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted. If the Supervisors are (or are deemed to be) not satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted sub-clauses 24(1)(a)-(c) shall apply. No Distribution Notice shall be issued during an Examination Period. For the avoidance of doubt, nothing in this sub-clause shall affect the Distribution Entitlement of any Scheme Creditor whose Admitted Scheme Claim has, prior to the commencement of the Examination Period, been the subject of a Distribution Notice. FURTHER DISTRIBUTIONS 25. (1) Any Scheme Consideration which has not been the subject of a Distribution Notice by the termination or expiry of the Waiting Period (in this clause "UNDISTRIBUTED SCHEME CONSIDERATION") shall, from the termination or expiry of the Waiting Period, be dealt with as set out in this clause. (2) Before the Undistributed Scheme Consideration (if any) shall be available for making further Distributions pursuant to this clause 25 to Admitted Scheme Creditors which have already received or become entitled to receive an Initial Distribution, the Undistributed Scheme Consideration shall be used to reimburse the Company for any SDRT Expense that it has incurred in excess of L500,000. For the avoidance of doubt, the Company shall have no right to receive any such reimbursement in respect of the first L500,000 of SDRT Expense it incurs. The Supervisors, acting reasonably, shall determine which Elements of Scheme Consideration shall be utilised to effect the reimbursement, converting Elements into money as the Supervisors, acting reasonably, deem necessary to enable the reimbursement to be made. The Supervisors shall give the necessary 210

II. THE CORP SCHEME -------------------------------------------------------------------------------- directions to the Escrow Trustee and the Distribution Agent to effect the reimbursement of the Company pursuant to this clause. (3) Thereafter the Undistributed Scheme Consideration shall be used to make further Distributions to Eligible Recipients on the following basis: (a) the distinction between the Known Claims Segment and the Reserve Claims Segment shall no longer be relevant and the remainder of the segments shall be aggregated for future Distribution purposes; (b) the Supervisors' approach to further Distributions shall be in accordance with the approach a liquidator would take following Liquidation Distribution Principles including the following concepts: (i) the setting of final dates by which a creditor must claim if it wishes to participate in a planned dividend; (ii) in the case of claims which have not been Admitted at the time of the declaration of a dividend to creditors, the taking into account of any such disputed claim in setting the dividend on a prudent basis so that if the disputed claim is later Admitted, the relevant creditor shall receive the dividend it would have received if and to the extent its claim had been Admitted at the date of the relevant dividend; (iii) generally, the concept of pari passu distribution; and (iv) any Scheme Creditor whose Scheme Claim is Admitted but whose Distribution Entitlement has not yet been satisfied shall be entitled to a Distribution in priority to the entitlement of other Admitted Scheme Creditors (whose entitlements to previous Distributions have been satisfied) to further Distributions until that Scheme Creditor is entitled to (and such entitlement is satisfied) the same rateable Distribution that other Admitted Scheme Creditors are entitled to (which entitlements have been satisfied). (4) The Supervisors, in deciding whether and, if so, when to direct a further Distribution, shall have regard to the cost of making the Distribution in relation to the value of the Undistributed Scheme Consideration to be distributed and may, acting reasonably, decide to delay directing a Distribution until such time (if any) as the costs of making the Distribution do not exceed the value of Scheme Consideration (or proceeds of sale of such Scheme Consideration) to be distributed. THE COMPANY AS A CREDITOR OF PLC 26. Property received or receivable by the Company from plc from time to time by virtue of the Company being a creditor of plc (whether pursuant to the plc Scheme, any other scheme of arrangement for plc, any voluntary arrangement for plc or any liquidation of plc or otherwise) shall be available for distribution and shall be distributed by the Company to Admitted Scheme Creditors subject to, at the time, in the manner and on the basis set out in the Scheme. In the light of the position of Ancrane as a Scheme Creditor and a Bondholder and the Ancrane Direction, this may involve successive distributions between the Company and plc, either notional or actual, as provided for in this Scheme and the plc Scheme. THE PLC DISTRIBUTION SUPPLEMENT 27. (1) Sub-clauses 27(2), (3) and (4) shall apply to the Initial Distribution if all of the conditions set out at (a) to (c) inclusive below are satisfied on the Effective Date: (a) the plc Scheme including provisions in the form or substantially the form of that set out in Schedule 2 becomes effective; (b) the plc Scheme supervisors admit the Company's claim against plc pursuant to the plc Scheme; and (c) (i) the Known Claim of Ancrane is Admitted by the Supervisors; or 211

II. THE CORP SCHEME -------------------------------------------------------------------------------- (ii) either (or both) of the Known Claims of the Eurobond Trustee are Admitted by the Supervisors; or (iii) either (or both) of the Known Claims of the Yankee Bond Trustee are Admitted by the Supervisors. (2) To give effect to clause 26 and on the conditions in sub-clause 27(1) being satisfied on the Effective Date, the Supervisors shall agree with the plc Scheme supervisors a distribution model simulating successive distributions to the Company in the plc Scheme and to plc in the Scheme (pursuant to the Ancrane Direction) (using the figures for the Company's claim against plc, Ancrane's claim against the Company as actually admitted by the Supervisors of the respective Schemes and Ancrane's holding of Bonds) in order to produce a net additional amount of Scheme Consideration available for Distribution to Admitted Scheme Creditors with the Initial Distribution (such net additional amount being the "PLC DISTRIBUTION SUPPLEMENT"). The plc Distribution Supplement shall be distributed to Eligible Recipients at the times and in the manner set out sub-clauses 27(3) and 27(4). (3) The Elements of the plc Distribution Supplement shall for these purposes be treated as being made up of two parts as follows: (a) the "KNOWN CLAIMS SUPPLEMENT" which shall be the plc Distribution Supplement less the Reserve Claims Supplement; and (b) the "RESERVE CLAIMS SUPPLEMENT" which shall be the same proportion of the plc Distribution Supplement as the Basic Reserve Claims Segment (which for this purpose shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected and the Distribution Entitlement of the Known Creditor who would have been entitled had its Known Claim been Admitted rather than Conclusively Rejected becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)) is of the Basic Scheme Consideration (which for this purpose shall be calculated after taking into account any decrease in the size of the Basic Known Claims Segment resulting from: (A) Known Claims being Conclusively Rejected resulting in a Rejected Claims Supplement being deducted from the Basic Known Claims Segment pursuant to sub-clause 29(1)(a) and becoming available for distribution to Scheme Creditors in accordance with sub-clause 29(2); and/or (B) Known Claims being Conclusively Rejected resulting in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)). (4) (a) The Elements of the Known Claims Supplement shall be distributed to Admitted Known Creditors at the same time as the Initial Distribution. (b) The Elements of the Reserve Claims Supplement shall be distributed to Admitted Reserve Creditors at the same time as the Initial Distribution. (5) (a) For the purposes of Distributions under the Scheme: (i) other than the Initial Distribution; and/or (ii) as regards the Initial Distribution if the provisions of sub-clauses 27(2)-27(4) inclusive do not come into force because one or more of the conditions in sub-clause 27(1) is not satisfied, the Supervisors may agree similar or analogous arrangements to those in sub-clause 27(2) (a "MODEL") with the supervisors of the plc Scheme (if any, or, if none, any other duly 212

II. THE CORP SCHEME -------------------------------------------------------------------------------- authorised representative of plc) where, acting reasonably, the Supervisors consider that to do so shall be in the interests of Admitted Scheme Creditors. (b) If a model is agreed pursuant to sub-clause 27(5)(a) prior to the expiry or termination of the Waiting Period, the equivalent of the plc Distribution Supplement thereby created shall be apportioned in the same manner as provided for in sub-clause 27(3), otherwise no apportionment shall be made. (c) Any supplement arising pursuant to sub-clause 27(5)(a)(ii) which shall be apportioned in accordance with sub-clause 27(5)(b) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (d) Any supplement arising pursuant to sub-clause 27(5)(a)(i) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 27(5)(b) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Receipts in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (e) Any supplement arising pursuant to sub-clause 27(5)(a)(i) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. PLC RECEIPTS 28. (1) As regards: (a) the Initial Distribution if the provisions of sub-clauses 27(2) - 27(4) above do not come into force for any reason; and (b) any Distributions other than the Initial Distribution, in each case, to the extent that relevant similar or analogous arrangements as referred to in clause 27(5) are not agreed in respect of the Company's entitlement to the plc Receipts, Admitted Scheme Creditors shall be entitled to all plc Receipts from time to time which shall be held on trust for Scheme Creditors under the Scheme. (2) If plc Receipts arise pursuant to sub-clause 28(1) prior to the expiry or termination of the Waiting Period, those plc Receipts shall be apportioned in the same manner as provided for in sub- clause 27(3), otherwise no apportionment shall be made. (3) Any plc Receipts arising pursuant to sub-clause 28(1)(a) which shall be apportioned in accordance with sub-clause 28(2) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (4) Any plc Receipts arising pursuant to sub-clause 28(1)(b) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 28(2) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (5) Any plc Receipts arising pursuant to sub-clause 28(1)(b) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. 213

II. THE CORP SCHEME -------------------------------------------------------------------------------- REJECTED CLAIMS 29. (1) Where a Known Claim is Conclusively Rejected before the expiry or termination of the Waiting Period, the Distribution Entitlement to which the Known Creditor would have been entitled, had its Known Claim been Admitted rather than Conclusively Rejected, shall: (a) if the quantum of the Known Claim which is Conclusively Rejected exceeds L250,000,000 (such Distribution Entitlement being a "REJECTED CLAIM SUPPLEMENT"), be deducted from the Known Claims Segment and be apportioned as follows: (i) the "KNOWN REJECTED CLAIM SUPPLEMENT" which shall be the Rejected Claim Supplement less the Reserve Rejected Claim Supplement; and (ii) the "RESERVE REJECTED CLAIM SUPPLEMENT" which shall be the same proportion of the Rejected Claim Supplement as the Basic Reserve Claims Segment (which for this purpose shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected and the Distribution Entitlement of the Known Creditor who would have been entitled had its Known Claim been Admitted rather than Conclusively Rejected becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)) is of the Basic Scheme Consideration (which for this purpose shall be calculated after taking into account any decrease in the size of the Basic Known Claims Segment resulting from: (A) Known Claims being Conclusively Rejected resulting in a Rejected Claims Supplement being deducted from the Basic Known Claims Segment pursuant to sub-clause 29(1)(a) and becoming available for distribution to Scheme Creditors in accordance with sub-clause 29(2); and/or (B) Known Claims being Conclusively Rejected resulting in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)); and (b) if the quantum of the Known Claim (or part thereof) which is Conclusively Rejected is less than or equal to L250,000,000, be deducted from the Known Claims Segment and form part of the Reserve Claims Segment and therefore not be available for distribution to Admitted Scheme Creditors as a Rejected Claim Supplement pursuant to sub-clause 29(2). (2) A Rejected Claim Supplement shall become available for distribution following apportionment under sub-clause 29(1)(a) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the amount of the Known Rejected Claim Supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the amount of the Reserve Rejected Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims. (3) For the purposes of distributing the Rejected Claim Supplement; if: (a) the plc Scheme including provisions in the form or substantially in the form of that set out in Schedule 2 becomes effective; (b) the plc Scheme supervisors admit the Company's claim against plc pursuant to the plc Scheme; (c) (i) the Known Claim of Ancrane is Admitted by the Supervisors; or (ii) either (or both) the Known Claims of the Eurobond Trustee are Admitted the Supervisors; or 214

II. THE CORP SCHEME -------------------------------------------------------------------------------- (iii) either (or both) the Known Claims of the Yankee Bond Trustee are Admitted by the Supervisors; and (d) the waiting period under the plc Scheme has not been terminated or expired, the Supervisors may agree similar or analogous arrangements to those in sub-clause 27(2) with the supervisors of the plc Scheme (if any, or, if none, any other duly authorised representative of plc) where, acting reasonably, the Supervisors consider that to do so would be in the best interests of Admitted Scheme Creditors. GENERAL PROVISIONS ON DISTRIBUTIONS 30. (1) No Scheme Creditor shall have any right to disturb a prior Distribution, whether on the grounds that there remains insufficient Scheme Consideration to satisfy that creditor's Distribution Entitlement (if any) or otherwise. (2) The Supervisors shall give all necessary directions and issue all necessary Distribution Notices to the Escrow Trustee (with a copy to the Distribution Agent) to enable Distributions to be made in accordance with the Scheme. The issue by the Supervisors of directions in accordance with this sub-clause 30(2) shall be a complete discharge of the Supervisors' responsibilities with respect to such Distributions. Without prejudice to the generality of the previous sentence, the Supervisors shall not be liable in any way whatsoever for any acts or omissions of the Escrow Trustee, the Distribution Agent or Bondholder Communications in respect of those directions. (3) Subject always to sub-clause 30(1) an Admitted Scheme Claim may be withdrawn or reduced as to the amount claimed by agreement between the Supervisors and the relevant Scheme Creditor. (4) Any sums of cash or rights or benefits paid, transferred or credited to the Escrow Trustee pursuant to clause 34 shall be distributed together with, or, as appropriate, in place of, and at the same time as, the New Rights to which such sum of cash or other rights or benefits relate. (5) (a) Elections may be made in Claim Forms and Account Holder Letters for the Eligible Recipient: (i) to receive any New Creditor Shares in the form of ADRs; and/or (ii) subject to the thresholds described in Recital J being met, to receive euro-denominated or US dollar-denominated New Senior Notes (but not both); and/or (iii) to receive any New Creditor Shares: (A) in certificated form; or (B) into an account held with CREST. (b) The Company shall pay any applicable SDRT Expense. (c) Where there are any New Creditor Shares which are not sufficient in number to equate to one ADR and which therefore cannot be transferred to the ADR Depositary in accordance with the terms of the Escrow and Distribution Agreement, the Supervisors shall direct the Escrow Trustee to procure that the Distribution Agent, acting on behalf of the Escrow Trustee shall sell those New Creditor Shares and remit the proceeds to augment the Reserve Claims Segment. (6) Eligible Recipients shall receive Distributions in accordance with the provisions of the Scheme provided that no fraction of a New Share and no fraction of a New Note shall be transferred, allotted or issued to any Eligible Recipient but: (a) if the New Creditor Shares or New Notes or any of them are Listed all fractions of such Listed New Creditor Shares or New Notes which, but for this proviso, any such Eligible 215

II. THE CORP SCHEME -------------------------------------------------------------------------------- Recipients would have received shall be aggregated and sold in the market and the net proceeds of sale shall comprise part of the Reserve Claims Segment; and (b) if any of the New Creditor Shares or New Notes are not listed, all entitlements of Eligible Recipients to all fractions of such New Creditor Shares and New Notes which, but for this proviso any such Eligible Receipts would have received, shall be rounded down to zero and the fractions shall comprise part of the Reserve Claims Segment. (7) (a) New Creditor Shares and New Notes will not be distributed to or to the order, or for the account or benefit, of any person where such distribution would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous. Where any determination is required as to whether the conditions or requirements of applicable law or regulation are "unduly onerous," such determination will be made by the Company with the advice of legal counsel and having due regard for the number of Scheme Creditors and Bondholders that are or may be located in the relevant jurisdiction, the value of the securities to which such persons are or may be entitled pursuant to the Scheme, the extent to which the requirements of the laws and regulations of such jurisdiction as applied to the Scheme are uncertain, the nature and extent of the risks or penalties associated with any violation of those legal or regulatory requirements and the costs, administrative burden and timing implications of taking such action (if any) as might permit distributions of securities to be made in that jurisdiction (including pursuant to any available exemptions) in accordance with applicable legal and regulatory requirements. (b) Notwithstanding the foregoing, distribution of New Creditor Shares and New Notes will not be refused on the grounds of any legal or regulatory prohibition of general application under the laws of any Unrestricted Jurisdiction, unless there has been a Change of Law. (c) New Creditor Shares and New Notes will not be distributed to or to the order of any Scheme Creditor or Bondholder located in a Restricted Jurisdiction, except that New Creditor Shares and New Notes will be distributed to or to the order of: (i) any Scheme Creditor or Bondholder located in France if the Scheme Creditor or (as the case may be) the Bondholder and any Designated Recipient of such Bondholder is a "qualified investor" as defined in Article L.411-2 of the French Monetary and Financial Code; (ii) any Scheme Creditor or Bondholder located in Italy, if CONSOB has confirmed that such distribution does not constitute a public offering under Italian securities legislation; (iii) any Bondholder located in Italy, if the number of such persons does not exceed 200; (iv) any Scheme Creditor other than a Bondholder located in Italy, if: (A) such person is a "professional investor" as defined in the Consolidated Financial Act Article 30, paragraph II and in CONSOB Regulation 11522/1998 Article 31, paragraph II; or (B) such person is not a "professional investor" as so defined but the number of such persons that are not "professional investors" does not exceed 200; and (v) any Scheme Creditor or Bondholder located in the US states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont if such persons falls within one of the relevant categories of persons set out in Schedule 4. Notwithstanding the foregoing, New Creditor Shares and New Notes may be distributed to or to the order of persons located in a Restricted Jurisdiction to the extent that there has been a Change of Law. 216

II. THE CORP SCHEME -------------------------------------------------------------------------------- (d) Notwithstanding the provisions of sub-clause (c) above, if the confirmations required by box 3 of the Claim Form or section 5, paragraphs (D), (E) and (F) of the Account Holder Letter are given in the form requested by the Claim Form or the Account Holder Letter (as the case may be), then distribution of New Creditor Shares and New Notes to or to the order of the relevant persons will not be refused on the grounds of any legal or regulatory prohibition of general application under the laws of any Restricted Jurisdiction, unless: (i) the Company determines that such confirmations have been given inappropriately on the basis that information provided in or in connection with the transmittal of the Claim Form or Account Holder Letter indicates that such Claim Form has been submitted by, or such Account Holder Letter has been delivered on behalf of, or delivery of securities is being requested to or for the account or benefit of, a person that is located in a Restricted Jurisdiction and that could not be eligible to receive the securities under any provision described in sub-clause 30(7)(c); (ii) the Company obtains actual knowledge that such confirmations are false; or (iii) there has been a Change of Law. Notwithstanding the foregoing, New Creditor Shares and New Notes will be distributed in Italy pursuant to sub-clauses 30(7)(c)(ii), 30(7)(c)(iv)(B) (to the extent applicable) without regard to whether the required confirmations have been inappropriately or falsely given in any relevant Claim Form or Account Holder Letter. (e) To the extent that New Creditor Shares or New Notes that would otherwise be deliverable pursuant to the Scheme cannot be delivered because of a legal or regulatory prohibition described in sub- clause 30(7) (a) above, such New Creditor Shares or New Notes will not be delivered and instead: (i) in the case of New Creditor Shares or New Notes that are listed on a securities exchange, such New Creditor Shares or New Notes will be sold and the net proceeds of such sale delivered to the relevant person in full satisfaction of the rights of such person in respect of such New Creditor Shares or New Notes under the Scheme, all as more particularly specified in the Escrow and Distribution Agreement; and (ii) in the case of New Creditor Shares or New Notes that are not listed on a securities exchange, the relevant person will receive a sum in cash which is substantially equivalent in value to such New Creditor Shares or New Notes, such sum to be determined by agreement between the Company and the Supervisors or absent such agreement by adjudication under Part VI and the Supervisors shall direct the sale of the New Creditor Shares and/or New Notes to which the relevant person would otherwise have been entitled. (8) The Supervisors shall give all appropriate directions to the Escrow Trustee (with a copy to the Distribution Agent) to give effect to this clause 30. (9) Any sale referred to in this clause 30 shall be made for the best terms reasonably available at the time of the sale and shall be undertaken on behalf of the person absolutely entitled to the relevant asset and none of the Supervisors, the Company, the Escrow Trustee, the Distribution Agent, the Registrars or any other person shall be responsible for any loss arising from the terms or timing of the sale. (10) For the avoidance of doubt, a Scheme Creditor must comply with the terms of the Scheme, including submitting a Claim Form in accordance with the provisions of clause 12, in order for its Eligible Recipient to receive any Distributions of Scheme Consideration to which that Scheme Creditor's Scheme Claim might entitle it. 217

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART IV FURTHER PROVISIONS REGARDING THE ISSUE OF NEW SHARES AND WARRANTS 31. The following shall apply in relation to the allotment and issue of the New Shares and the Warrants in pursuance of the Scheme: (1) The New Shares shall be allotted and issued by the Company to the Escrow Trustee by means of credit to an appropriate CREST account of the Escrow Trustee or its nominee. (2) Each New Share shall be allotted and issued credited as fully paid in consideration of: (a) the release of Scheme Claims which are the subject of the First Initial Distribution Notice on the basis set out in the Scheme; and/or (as the case may be) (b) the agreement of Scheme Creditors with other Scheme Claims not to commence or continue Prohibited Proceedings in respect of such Scheme Claims as set out in clauses 2 to 5, (such consideration being in aggregate net of the amount of the Cash and the face value of the New Notes). (3) The plc Shareholders shall receive the plc Shareholder Stock on the following basis: (a) each plc Shareholder shall be provisionally allocated one New Share from the plc Shareholder Stock in respect of every 559 ordinary shares of nominal value 5p each in the capital of plc ("PLC SHARES") which it holds on the last day of dealings in those shares prior to the Effective Date (the "REGISTER DATE"). No fractions of New Shares shall be provisionally allocated to plc Shareholders. (b) each plc Shareholder who holds less than 559 plc Shares at the Register Date shall be allocated one New Share from those New Shares not distributed by virtue of the prohibition against the allocation of fractions of New Shares set out in sub-clause 31(3)(a) ("RESIDUAL SHARES"). If there are insufficient Residual Shares to enable one New Share to be allocated to each such plc Shareholder (the "SHORTFALL"), sub-clause 31(3)(c) shall apply until the Shortfall has been eliminated. If there are Residual Shares in excess of the number of New Shares required to ensure that each plc Shareholder is allocated one New Share from the plc Shareholder Stock pursuant to sub-clause 31(3)(a) (the "EXCESS"), sub-clause 31(3)(d) shall apply. (c) (i) One New Share shall be deducted from the provisional allocation of each plc Shareholder beginning with the plc Shareholder receiving the highest provisional allocation (from which no New Share has been deducted under this sub-clause) and continuing with the plc Shareholder with the next highest provisional allocation. (ii) Where more than one plc Shareholder has the same provisional allocation and a deduction pursuant to sub-clause 31(3)(c)(i) is required to be made from the provisional allocation of one such plc Shareholder, such deduction shall be made in the alphabetical order of the first letter of the surname or corporate name (or first surname or corporate name if more than one) of such plc Shareholders as they appear in the register of the members of plc. (iii) Deductions pursuant to sub-clauses 31(3)(c)(i) and 31(3)(c)(ii) shall continue until the number of New Shares so deducted equals the Shortfall. (d) (i) If the Company reasonably believes that the New Shares shall be (and they are in fact) Listed within 30 Business Days of the Effective Date, the Registrars shall use reasonable endeavours to procure the sale of the Excess on the London Stock Exchange and the net proceeds of sale shall be paid to the Company for its benefit. 218

II. THE CORP SCHEME -------------------------------------------------------------------------------- (ii) In any other circumstances, the Registrars shall use reasonable endeavours to procure the sale of the Excess and the net proceeds of such sale shall be paid to the Company for its benefit. (e) Once the provisional allocations under this sub-clause have been finalised they shall be treated as final allocations and distributed to plc Shareholders as soon as reasonably practicable in the manner provided for in the Escrow and Distribution Agreement. (4) The Warrants shall be allotted and issued by the Company prior to the Effective Date and the Registrars shall hold the Warrants for the benefit of the plc Shareholders to be distributed to (or, as the case may be, sold in the market as provided in sub-clause 31(6)(b)) as directed by the Company in accordance with the terms of the Scheme. (5) Each plc Shareholder shall be allocated one warrant in respect of every 56 plc Shares which it holds at the Register Date. No fractions of Warrants shall be allocated to plc Shareholders. (6) (a) New Shares and Warrants will not be distributed to or to the order, or for the account or benefit, of any plc Shareholder where such distribution would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous (determined in accordance with sub-clause 30(7)(a)). Accordingly, (i) New Shares and Warrants will not be distributed to any plc Shareholder that is shown in the register of plc Shareholders as having a registered address in Malaysia, unless there has been a Change of Law; and (ii) Warrants will not be distributed to any plc Shareholder that is shown in the register of plc Shareholders as having a registered address in Italy, unless: (A) CONSOB has confirmed that such distribution does not constitute a public offering under Italian securities legislation; or (B) the number of such plc Shareholders does not exceed 200; or (C) there has been a Change of Law. (b) To the extent that New Shares or Warrants that would otherwise be deliverable to a plc Shareholder cannot be delivered because of a legal or regulatory prohibition described in sub-clause 31(6)(a) above, such New Shares or Warrants will not be delivered and instead the Registrars shall use reasonable endeavours to sell such New Shares or Warrants and will pay the net proceeds of such sale (if any) to the relevant plc Shareholder in full satisfaction of the rights of such plc Shareholder in respect of such New Shares or Warrants under the Scheme, all as more particularly specified in the Escrow and Distribution Agreement. (7) Any sale pursuant to clause 31 shall be for the best terms reasonably available at the time of the sale and shall be undertaken on behalf of the relevant plc Shareholders and none of the Supervisors, the Company, the Escrow Trustee, the Distribution Agent, the Registrars or any other person shall be responsible for any loss arising from the terms or timing of the sale or the failure to procure any purchaser for all or any plc Shareholder Stock or Warrants to be sold pursuant to clause 31. 32. The plc Shareholder Stock and the Warrants shall only be available for the purposes of Distributions to plc Shareholders (or sale) pursuant to clause 31. 219

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART V ESCROW AND DISTRIBUTION ARRANGEMENTS ESCROW AND DISTRIBUTION AGREEMENT 33. On the Effective Date, those provisions of the Escrow and Distribution Agreement which have not already come into force shall come into force in accordance with its terms. In particular, but without limitation, the Company, forthwith upon the Effective Date, shall allot and issue or, as the case may be, pay the Basic Scheme Consideration (and the plc Shareholder Stock) to the Escrow Trustee or its nominee to be dealt with in accordance with the Escrow and Distribution Agreement. Any plc Receipts shall (as soon as practicable after receipt by the Company) be paid or transferred to the Escrow Trustee to be dealt with in accordance with the Escrow and Distribution Agreement. SCHEME CONSIDERATION AND PLC SHAREHOLDER STOCK WHEN HELD IN ESCROW BY THE ESCROW TRUSTEE 34. All of the Scheme Consideration allotted, issued and/or transferred to the Escrow Trustee or its nominee shall be held by the Distribution Agent or the Escrow Trustee's nominee, as the case may be as custodian for the Escrow Trustee. The Escrow Trustee shall hold that Scheme Consideration on bare trust absolutely for the Scheme Creditors on the basis set out in the Escrow and Distribution Agreement and all of the plc Shareholder Stock allotted, issued or transferred to the Escrow Trustee shall be held by the Escrow Trustee on trust absolutely for the plc Shareholders. In each case and so as to bind the Scheme Creditors and any person deriving title from them, the Scheme Consideration shall be applied by the Escrow Trustee on behalf of the Scheme Creditors absolutely entitled to it, in accordance with the Escrow and Distribution Agreement and the provisions of the Scheme. Subject to the provisions of the Escrow and Distribution Agreement, the Escrow Trustee shall at no time whatsoever, either present or future, have any beneficial interest in the Scheme Consideration or the plc Shareholder Stock. 35. Whilst any New Shares, New Notes or any Cash are held by, or on behalf of, the Escrow Trustee: (1) dividends paid on (or any other rights or benefits added or attached to) such New Shares; and/or (2) interest accrued on any such Cash or interest paid on any such New Notes; and/or (3) any cash arising from the prepayment by the Company of any such New Senior Notes or New Junior Notes in accordance with their terms and any interest accruing thereon, shall be paid, transferred or credited to the Escrow Trustee to hold on the terms of the Escrow and Distribution Agreement. 36. The Escrow Trustee shall not exercise any voting rights attaching to any New Notes or New Shares held in escrow. 37. (1) The Escrow Trustee's liabilities as trustee shall be solely those arising out of its trusteeship and other obligations set out in the Escrow and Distribution Agreement. (2) The Distribution Agent's liabilities as custodian for the Escrow Trustee and as distribution agent shall be solely those arising out of its custodianship and other obligations set out in the Escrow and Distribution Agreement. 220

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART VI INDEPENDENT ADJUDICATION 38. If any question or issue in relation to the existence or quantum of a Scheme Claim shall be referred for adjudication as a result of an election made pursuant to clause 17 or the question of what sum an Eligible Recipient shall be entitled to shall be referred for adjudication pursuant to sub-clause 30(7)(e)(ii) the question or issue shall be referred for adjudication to an individual agreed between the Supervisors and the relevant Scheme Creditor (the "COUNTERPARTY"), such individual to be an independent third party considered by the Supervisors and the Counterparty to be a fit and proper person duly qualified to adjudicate on the question or issue, or in the absence of any such agreement between the Supervisors and the Counterparty within 10 Business Days of the election, to an individual nominated by The President of the Law Society of England and Wales. 39. The individual to whom the question or issue is referred (the "ADJUDICATOR") shall be entitled to prescribe such reasonable provisions and procedures as, in his absolute discretion, he may consider appropriate for the purposes of assisting him in reaching his decision, and shall be entitled for such purpose to call for such evidence in relation to the question or issue referred to him as he may require, provided that the Counterparty and the Company shall always be afforded a reasonable opportunity to make oral submissions to the Adjudicator. In any one adjudication, such oral submissions shall not in aggregate occupy more than one working day save with the approval, in his absolute discretion, of the Adjudicator. 40. With regard to any adjudication before him, the Adjudicator may make such directions in respect of payment of his remuneration and in respect of the costs, charges and expenses incurred by him, the Supervisors, the Company or the Counterparty as he shall think just. In particular, but without limitation, one party may be directed to pay remuneration and costs, charges and expenses of another party if, in the opinion of the Adjudicator, any such party has made a claim, relied on a defence or otherwise howsoever conducted himself in relation to the adjudication in a manner which is frivolous, vexatious or had no reasonable prospect of success. 41. If the Adjudicator shall direct that any such remuneration, costs, charges and expenses be paid by the Supervisors or by the Company, the same shall forthwith be paid in full by the Company. 42. If the Adjudicator shall direct that any such remuneration, costs, charges and expenses be paid by the Counterparty, the same shall forthwith be paid in full by the Counterparty and, if not so paid then, for the purposes of determining whether such Counterparty is entitled to participate in any Distribution under the Scheme, he shall be treated as having received on account an advance distribution under the Scheme equal to the amount which he has been directed to pay. 43. Subject to any directions which may be given by the Adjudicator in accordance with clause 40, the Company shall pay all costs, charges and expenses incurred by the Adjudicator in the course of exercising and performing his powers, duties and functions under the Scheme and shall pay such remuneration to the Adjudicator for the exercise and performance of his powers, duties and functions as may be agreed between the Adjudicator and the Supervisors and approved by the Creditors' Committee. 44. The Adjudicator shall notify the Supervisors and the relevant Counterparty of his decision by notice in writing by Post as soon as practicable. 45. Subject to any mandatory applicable law, the determination of the Adjudicator of any question or issue shall be final and binding on the Company, the Supervisors and the Counterparty and, for the avoidance of doubt, there shall be no right of appeal therefrom, and no right to make any claim against the Adjudicator in respect thereof. For the avoidance of doubt, this exclusion of any right of appeal shall operate only to the extent permitted by law. 46. If at the expiration of 6 months in the case of a question or issue referred for adjudication as a result of an election made pursuant to clause 17 or of 3 months in the case of a question or issue referred for adjudication pursuant to sub-clause 30(7)(e)(ii) no decision on such question or issue has been reached by an Adjudicator, then nothing in this Scheme shall preclude the Counterparty from taking any appropriate action in the Court for the purposes only of securing a determination of the question or issue concerned. 221

The Supervisors shall have the powers, duties and functions conferred upon them by the Scheme and any other documents entered into pursuant to the Scheme. 48.

II. THE CORP SCHEME -------------------------------------------------------------------------------- 55. Without prejudice to the generality of clause 53, in carrying out their functions and powers under the Scheme, the Supervisors shall be entitled: (1) to admit or refuse to admit Scheme Claims Submitted by Scheme Creditors (including to ensure the Company properly conducts its defence of any Prohibited Proceedings and/or any Allowed Proceedings) and direct: (a) Distributions; and (b) realisations of Scheme Consideration to generate cash for Distributions by the Distribution Agent in accordance with the Scheme and the Escrow and Distribution Agreement; (2) to have access at all reasonable times to all relevant employees, books, papers and other documents of the Company and to receive all such information from the Company as they may reasonably require in relation to their duties as Supervisors and to receive the reasonable co-operation of the Company in connection with the conduct of any Prohibited Proceedings, any Allowed Proceedings or defending any Proceedings against the Supervisors in respect of carrying out their functions and exercising their powers under the Scheme; (3) to delegate to any Employee all or any of the functions, powers, rights, authorities and discretions conferred upon the Supervisors under the Scheme and from time to time to revoke any such delegation, provided that the Supervisors shall be responsible for any act or omission of any such employee or delegate to the same extent as if they had expressly authorised it; (4) to be remunerated by the Company for the carrying out of such functions and powers (in the case of the initial Supervisors, Philip Wedgwood Wallace and Richard Heis, such remuneration to be calculated by reference to the Supervisors' Engagement Letter) and to be reimbursed by the Company for all expenses properly incurred by them in connection with this clause including any adverse costs ordered to be paid by the Supervisors as a result of any Proceeding in connection with the Scheme; (5) to defend any proceedings against them in respect of carrying out their functions and exercising their powers under the Scheme; (6) to apply to the Court for directions in relation to any particular matter arising in the course of the Scheme; (7) to liaise with the Creditors' Committee and to attend Creditors' Committee meetings; (8) to convene a meeting of Scheme Creditors in accordance with Part IX, if appropriate; and (9) to exercise such powers as are necessary or desirable to enable them to fulfil their functions under the Scheme and to do all other things incidental to the exercise of the functions and powers referred to in this and clause 53. 56. Save as expressly set out in this Scheme, the Supervisors shall be entitled to employ and remunerate accountants, actuaries, lawyers and other professional advisers or agents in connection with the conduct of their functions and powers under the Scheme. 57. Any function of or power conferred on the Company or its officers, whether by statute or by its memorandum or articles of association, which could be exercised in such a way as to interfere with the exercise by the Supervisors of their functions and powers in relation to the Company or the Scheme, shall not be so exercised except with the consent of the Supervisors, which may be given either generally or in relation to particular cases. Any such consent given by the Supervisors may be withdrawn. 58. In carrying out their functions and exercising their powers under the Scheme, the Supervisors shall act bona fide and with due care and diligence in the interests of the Scheme Creditors as a whole and they shall use their powers under the Scheme for the purpose of ensuring that the Scheme is operated in accordance with its terms. 223

(2) The Company shall indemnify the Supervisors for any Liability incurred by the Supervisors arising out of or in connection with making or having made any Distributions in accordance with the terms of the Scheme save to the extent that such Liability arises from the Supervisors own negligence, wilful default, breach of duty, breach of trust, fraud or dishonesty (or as a result of the negligence, wilful default, breach of duty, breach of trust, fraud or dishonesty of any Employee). 60. (1) To the extent permitted by law, no Scheme Creditor shall be entitled to challenge the validity of any act done or omitted to be done in good faith and with due care by the Supervisors in accordance with and to implement the provisions of the Scheme or the exercise by the Supervisors in good faith and with due care of any power conferred upon them for the purposes of the Scheme if exercised in accordance with and to implement the provisions of the Scheme and the Supervisors shall not be liable for any loss unless such loss is attributable to their own negligence, default, breach of duty, breach of trust, fraud or dishonesty (or to the negligence, default, breach of duty, breach of trust, fraud or dishonesty of any Employee).

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART VIII CREDITORS' COMMITTEE CONSTITUTION OF THE CREDITORS' COMMITTEE 62. (1) There shall be a Creditors' Committee under the Scheme.

PROCEEDINGS OF THE CREDITORS' COMMITTEE 72. Save as otherwise specifically provided in the Scheme, the Creditors' Committee may convene, adjourn and otherwise regulate its meetings in such manner as it considers appropriate. Subject to clause 77, the quorum at any meeting of the Creditors' Committee shall be at least two-thirds of the Committee Members, provided that if a quorum is not present within 30 minutes from the time appointed for a meeting, or if during a meeting such a quorum ceases to be present, the meeting shall stand adjourned to such time and place as may be determined by the majority of the Committee Members present and the Committee Members present at any such meeting reconvened following an adjournment shall constitute a quorum. Each Committee Member shall have one vote and, except as otherwise provided in the Scheme, matters arising at a meeting shall be decided by a majority of votes cast at the meeting. 227

II. THE CORP SCHEME -------------------------------------------------------------------------------- 73. The Creditors' Committee shall meet at least once every 12 months for the purpose of receiving a report from the Supervisors on the progress of the Scheme. The Creditors' Committee shall hold such further meetings as it considers desirable for the purpose of performing its functions under the Scheme. A meeting of the Creditors' Committee shall be called as soon as reasonably practicable if so requested by at least two Committee Members or if the Supervisors otherwise consider it appropriate. Except with the consent of all Committee Members, no meeting of the Creditors' Committee may be called on less than ten Business Days' notice and, except with the consent of all Committee Members, no business may be transacted at any such meeting other than that set out in the notice of that meeting. 74. The Supervisors shall convene a meeting of the Creditors' Committee as soon as reasonably practicable after the end of the Waiting Period. 75. Each Committee Member (including any Nominated Representative or Alternate) and the Supervisors (or their representatives) shall be entitled to attend and receive notice of all meetings of the Creditors' Committee. The Supervisors shall be entitled to attend and speak, but not to vote, at all meetings of the Creditors' Committee. If so requested by the Creditors' Committee, the Supervisors (or their representative(s)) shall absent themselves from such part of a meeting of the Creditors' Committee as the Creditors' Committee may specify. 76. Proper minutes shall be kept of all proceedings of the Creditors' Committee and such minutes shall at all reasonable times be open to inspection by (subject to clause 81) any Committee Member. Copies of such minutes shall be sent as soon as practicable after each meeting to the Supervisors and each Committee Member. 77. A Committee Member (including any Nominated Representative or Alternate) and the Supervisors may participate in a meeting of the Creditors' Committee through the medium of conference telephone or similar form of communication equipment if all persons participating in the meeting are able to hear and speak to each other throughout the meeting. A person participating in this way is deemed to be present in person at the meeting and, in the case of a Committee Member (including any Nominated Representative or Alternate), is counted in a quorum and entitled to vote. All business transacted in this way by the Creditors' Committee is deemed to be validly and effectively transacted at a meeting of the Creditors' Committee although fewer than two-thirds of the Committee Members are physically present at the same place. If, at any time during a Committee Meeting any person participating in the meeting ceases to be able to hear and speak to all other Committee Members, Nominated Representatives or Alternates, whether participating in the Committee Meetings through the medium of conference telephone or similar form of communication equipment or in person, the meeting shall be adjourned and reconvened when full communication between those Committee Members attending the meeting is restored. 78. Other than in relation to such a resolution as is referred to in clause 82, a resolution in writing signed by all Committee Members for the time being shall be valid and effective as if passed at a meeting of the Creditors' Committee duly convened and held. POWERS 79. (1) The Creditors' Committee shall have the powers specifically set out in the Scheme. (2) If the Supervisors determine that the costs of making any further Distribution of Scheme Consideration would exceed the value of the Scheme Consideration remaining to be distributed, the Creditors' Committee may direct the Supervisors to procure the sale of such Scheme Consideration and distribute the proceeds of that sale provided that the costs of making such Distributions do not exceed the proceeds of sale to be distributed. 80. Before each meeting of Scheme Creditors convened pursuant to clause 93 the Supervisors shall submit to the Creditors' Committee a report on the operation of the Scheme during the period since the last such report was prepared (or, in the case of the first such meeting, since the Effective Date) and shall (or shall appoint a representative to) attend at any meeting of the Creditors' Committee at which that report is considered for the purpose of giving such explanations and information as the Creditors' Committee may 228

II. THE CORP SCHEME -------------------------------------------------------------------------------- require. A copy of that report, incorporating such amendments (if any) as may be agreed by the Supervisors and the Creditors' Committee, shall be made available to Scheme Creditors in accordance with clauses 95 and 96. 81. The Creditors' Committee may from time to time resolve to seek information from the Supervisors concerning the operation of the Scheme, and may depute any one Committee Member to apply in writing to request and receive from the Supervisors any or all such information. The Supervisors shall promptly give to the Creditors' Committee all such information reasonably requested concerning the operation of the Scheme as the Creditors' Committee shall from time to time resolve to seek and in respect of which a written request shall have been received by the Supervisors. Each Committee Member shall be entitled at any time to raise questions or to request a meeting with the Supervisors in connection with the performance of his responsibilities as a Committee Member and, subject to their duties under the Scheme the Supervisors shall use reasonable endeavours to respond to such questions or to comply with any such request for a meeting. Notwithstanding the preceding provisions of this clause, the Supervisors shall not be obliged to disclose: (1) any confidential information of the Company to a Committee Member if the information relates, or the Supervisors reasonably believe that the information relates, to any matter where such Committee Member has an interest in conflict with the Company (other than a general conflict arising as a result of the status of the Committee Members (or their appointors) as Scheme Creditors); or (2) any information which could cause the Company to breach insider dealing rules, the Financial Services and Markets Act 2000 or the Listing Rules of the UKLA. 82. The Creditors' Committee shall be entitled: (1) by a resolution passed by at least three-fourths of all of the Committee Members present and voting at any time to call upon a Supervisor to resign, provided that each such Supervisor and each Committee Member have been given at least 20 Business Days' notice of the proposed resolution and of the reasons why the resolution is to be put to the Creditors' Committee and have been given a reasonable opportunity to make representations at the meeting at which the resolution is proposed. If the Supervisor declines to resign within 5 Business Days of a resolution of the Creditors' Committee calling for his resignation, a resolution requiring his removal shall be put before the next meeting of the Scheme Creditors and, if passed, the Supervisor shall vacate the office of Supervisor; (2) upon removal of a Supervisor or if a Supervisor ceases to hold office for any other reason, to appoint any person qualified to act under clause 48 to be a Supervisor in their place (and a resolution requiring ratification of such appointment shall be put before the next meeting of Scheme Creditors pending which the appointee shall have full power to act as a Supervisor) save that if a resolution is passed at a meeting of Scheme Creditors requiring the removal of any of the Supervisors pursuant to sub-clause 82(1) such appointment may be made by the Scheme Creditors at such meeting. 83. The Creditors' Committee shall be entitled to engage legal and financial advisers from time to time as reasonable in order to assist them in carrying out their functions as the Creditors' Committee. At any particular time, the Creditors' Committee may only engage one legal and one financial adviser. Reasonable costs of such advisers shall be paid by the Company. 84. The Creditors' Committee and the Company shall use reasonable endeavours to ensure that there are two duly qualified Supervisors in office at all times. DUTIES 85. Each Committee Member, each Nominated Representative, and each Alternate shall, in performing their functions as such in relation to the Scheme, act bona fide in what he or she reasonably considers to be the interests of the Scheme Creditors as a whole. For the avoidance of doubt (but without prejudice to its 229

II. THE CORP SCHEME -------------------------------------------------------------------------------- specific powers as set out by the Scheme) it shall not be the duty of the Creditors' Committee to monitor the carrying out of the Scheme or the activities of the Supervisors. 86. It shall be the duty of each Committee Member who is in any way, whether directly or indirectly, interested in a contract or arrangement or proposed contract or arrangement with the Company (other than any which arises as a result of the provisions of the Scheme) to declare (or procure that its Nominated Representative or Alternate shall declare) the nature of his or its interest at a meeting of the Creditors' Committee. For this purpose a general notice given to the Creditors' Committee to the effect that a Committee Member is an associate (within the meaning of section 435 of the Insolvency Act 1986) of a specified company or firm and is to be regarded as interested in any contract with that company or firm shall be deemed a sufficient declaration of interest in relation to any such contract or arrangement. Such a Committee Member shall not be counted in the quorum, shall not be entitled to vote in relation to any matter relating specifically to any such contract, shall retire from the meeting for so long as the matter is discussed and voted upon and shall not receive any information, nor be entitled to inspect any part of the minutes of a meeting of the Creditors' Committee, relating thereto. 87. Each Nominated Representative or Alternate shall be entitled to report to the Committee Member appointing him on the proceedings of the Creditors' Committee and, so far as necessary for that purpose, to disclose confidential information of the Company to those officers, employees and professional advisers of that member or appointor who need to know it in connection with (where a Nominated Representative or Alternate is disclosing information) the performance of his or its responsibilities as a Committee Member, provided that such information does not to his or its knowledge (after due enquiry) relate to any matter where any such appointor has an interest in conflict with the Company (other than a general conflict arising as the result of the status of Committee Members or the appointors of a Nominated Representative or Alternate as Scheme Creditors). Each Committee Member shall, and shall procure that its Nominated Representative or Alternate and its officers, employees and professional advisers shall, preserve the confidentiality of such information and shall use such information only for the purposes of performing their responsibilities and functions (or their Nominated Representative's or Alternate's responsibilities and functions) in relation to the Creditors' Committee. RESPONSIBILITY 88. No Scheme Creditor, Supervisor or the Company shall be entitled to challenge the validity of any act done or omitted to be done in good faith by any Committee Member (or Nominated Representative or Alternate) in accordance with and to implement the provisions of the Scheme or the exercise by any such Committee Member (or Nominated Representative or Alternate) in good faith of any power conferred upon it or him by or for the purposes of the Scheme if exercised in accordance with and to implement the provisions of the Scheme and no such Committee Member (or Nominated Representative or Alternate) shall be liable for any loss or damage unless such loss or damage is attributable to its or his own wilful default, fraud, dishonesty or wilful breach of duty. VALIDATION OF ACTS 89. All acts done by the Creditors' Committee or any member of the Creditors' Committee or any person acting as a Committee Member or as a Nominated Representative or Alternate shall, notwithstanding that it is afterwards discovered that there was some defect in the appointment of a Committee Member or person acting as aforesaid, or that any of them were disqualified, be valid as if every such person had been duly appointed and qualified. EXPENSES 90. Each member of the Creditors' Committee, each Nominated Representative and each Alternate shall be entitled to be reimbursed by the Company upon written demand to the Company and the Supervisors for their reasonable out of pocket expenses incurred in attending meetings of the Creditors' Committee, provided that such meetings are held in London or in such other place as the Supervisors may from time to time agree. Where a Committee Member, its Nominated Representative or any Alternate appointed by 230

II. THE CORP SCHEME -------------------------------------------------------------------------------- the Committee Member or its Nominated Representative must travel to attend a Creditors' Committee meeting in London (or such other place as the Supervisors have agreed), that Committee Member or Nominated Representative shall (and that Alternate shall procure that the Committee Member or Nominated Representative shall) use all reasonable endeavours to appoint as its Nominated Representative or Alternate (as the case may be) for that meeting an individual who is based in locality of the venue of that Creditors' Committee meeting. The Supervisors, acting reasonably, may permit the reasonable out of pocket expenses incurred by a member of the Creditors' Committee, Nominated Representative or Alternative to include the costs of an air fare required to allow such Committee Member, Nominated Representative or Alternate to attend the Creditors' Committee meeting. Where the cost of an air fare is so permitted, it shall be the cost of an economy class fare only. NO CREDITORS' COMMITTEE 91. (1) If at any time there are less than three members of the Creditors' Committee or such lesser number as permitted by sub-clause 62(2), the Creditors' Committee may continue to exercise all its functions under the Scheme (other than those provided for in clause 82 and sub-clause 93(2)) for a period of 28 days, during which time the remaining Committee Members shall endeavour to fill the vacancies on the Creditors' Committee. (2) If the Committee Members fail to fill vacancies on the Creditors' Committee within such period of 28 days, the Supervisors shall use reasonable endeavors to appoint, within a further 14 days, such additional Scheme Creditors ("INTERIM APPOINTEES") to the Creditors' Committee as are required to fill such vacancies. Interim Appointees may appoint a Nominated Representative or Alternate pursuant to sub-clauses 62(4) and 62(5). (3) In appointing any Interim Appointees pursuant to sub-clause 91(2), the Supervisors shall endeavour to ensure that the composition of the Creditors' Committee including such Interim Appointees is such as to represent a proper balance of the interests of the Scheme Creditors as a whole. (4) In the event of vacancies on the Creditors' Committee being filled, whether by appointees of the Creditors' Committee pursuant to sub-clause 91(1) or by Interim Appointees appointed by the Supervisors pursuant to sub-clause 91(2), the full powers and functions of the Creditors' Committee under the Scheme shall be restored, provided that no Interim Appointee shall be entitled to vote in relation to any resolution to appoint an additional Committee Member. (5) Any Interim Appointee shall be liable to be removed as a Committee Member at any time without notice if the Creditors' Committee (excluding any Interim Appointees) appoints a Scheme Creditor to fill the vacancy which had been filled by such Interim Appointee. (6) If at any time after the operation of this clause there are no members of the Creditors' Committee, the Supervisors shall be entitled to continue to carry out their functions and exercise the necessary powers pursuant to the terms of the Scheme, save that the Supervisors shall not be required to provide reports to the Creditors' Committee or obtain the approval of the Creditors' Committee for the purposes of clause 115. 92. If, following the procedure set out in clause 91, there are less than three Committee Members (including Interim Appointees) or such lesser number as permitted by sub-clause 62(2) then, for so long as that is the case, the Creditors' Committee shall not exercise any functions or have any powers under the Scheme and the following provisions shall apply: (1) the Supervisors shall use reasonable endeavours to find additional Committee Members to enable it to function; (2) any Supervisor may resign under clause 49 provided that a replacement Supervisor is appointed in his place at a meeting of the Scheme Creditors pursuant to a resolution proposed by the Supervisors; 231

II. THE CORP SCHEME -------------------------------------------------------------------------------- (3) any Supervisor may be removed provided that a replacement Supervisor is appointed in his place at a meeting of the Scheme Creditors pursuant to a resolution proposed by any ten Scheme Creditors who have Scheme Claims of an aggregate value in excess of 15 per cent. of all Scheme Claims or any 30 Scheme Creditors; and (4) the requirements for obtaining the consent, approval of and for consulting with or notifying the Creditors' Committee and for submitting a report to the Creditors' Committee shall be suspended. 232

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART IX MEETINGS OF SCHEME CREDITORS CONVENING OF MEETINGS 93. Meetings of Scheme Creditors are to be convened as follows: (1) The Supervisors shall convene a meeting of the Scheme Creditors at least once every 12 months unless the Supervisors and the Creditors' Committee agree otherwise. (2) The Creditors' Committee may at any time require the Company to convene a meeting of the Scheme Creditors to consider a resolution: (a) for the removal of a Supervisor pursuant to sub-clause 82(1); (b) for the appointment of a Supervisor pursuant to sub-clause 82(2); or (c) for such other purpose as it thinks fit. (3) The Supervisors may at any time convene a meeting of the Scheme Creditors for such purpose as they think fit. (4) Any five or more Scheme Creditors who have Scheme Claims of an aggregate value in excess of 15 per cent. of all Admitted and Unadmitted Scheme Claims or any 20 Scheme Creditors may by notice in writing signed by them or on their behalf and deposited at the registered office of the Company require the Supervisors to convene a meeting of Scheme Creditors for such purpose as they think fit. The relevant Scheme Creditors must specify the purpose for which the meeting is required and it shall be the duty of the Supervisors forthwith to summon a meeting of Scheme Creditors for that purpose and to give such notice of the meeting as is necessary to enable such purpose to be carried out effectively in accordance with the provisions of the Scheme. 94. The Company may appoint a representative or representatives to attend any meeting of Scheme Creditors for the purposes of observing the meeting only. 95. There shall be laid before each meeting of Scheme Creditors convened pursuant to clause 93 the report referred to in clause 80 unless the Supervisors and the Creditors' Committee agree that any such meeting should not be held, in which case a copy of the report shall be sent by the Supervisors to Scheme Creditors upon request from the Scheme Creditors to the Supervisors. 96. At least 20 Business Days' notice shall be given of a meeting of Scheme Creditors. Such notice shall be exclusive of the day on which it is served or deemed to be served and of the day for which it is given, and shall (in the case of a meeting convened pursuant to clause 93) specify the place and time of the meeting and the place from which a copy of the report referred to in clause 80 can be obtained by Scheme Creditors upon request from the Scheme Creditors to the Supervisors prior to the meeting. 97. Any costs incurred in the production and distribution of the report referred to in clause 80 shall be borne by the Company. 98. Notice of a meeting of Scheme Creditors shall be given by the Supervisors or the Creditors' Committee, as the case may be, convening the meeting: (1) to each Admitted Scheme Creditor, and to any other Scheme Creditor who has applied in writing to the Company to receive notice of such meeting, by sending a notice by Post to such Scheme Creditor at his last known address; (2) to all other Scheme Creditors by placing advertisements containing the requisite information in such newspaper or newspapers as the Supervisors shall consider appropriate; (3) where called by the Creditors' Committee, to the Supervisors; (4) where called by the Supervisors, to each Committee Member; and (5) the Company. 233

II. THE CORP SCHEME -------------------------------------------------------------------------------- 99. The accidental omission to give notice of a meeting of Scheme Creditors to, or the non-receipt of a notice of such a meeting by, any person entitled to receive notice shall not invalidate the proceedings at that meeting. RESOLUTIONS 100. If a meeting of Scheme Creditors is convened at a time when a resolution is to be put to the next meeting of Scheme Creditors pursuant to clause 65, the business of the meeting shall include the resolution concerned, and in the case of a resolution to remove a Supervisor pursuant to sub-clause 82(1) which, if passed, would result in there being less than two Supervisors in office, shall also include a resolution that a named person qualified to act under clause 48 and willing to be appointed, be appointed as a Supervisor in their place. 101. No meeting shall be validly convened unless the notice of the meeting sets out the text of each resolution or an adequate summary thereof, which is to be proposed at the meeting (or if no resolution is to be proposed at the meeting, the nature of the business to be discussed thereat) and (in the case of a notice which is sent by Post) is accompanied by a letter explaining (in relation to each such resolution) why the meeting is being convened. VOTING 102. A resolution put to a meeting of Scheme Creditors shall be effective only if it is approved by a majority in number representing three-fourths in value of the Scheme Claims of Scheme Creditors which are present and voting either in person or by proxy at the meeting. 103. Every Scheme Creditor entitled to vote shall have the right to appoint any person as his proxy to attend and vote instead of him. The instrument appointing a proxy may be in any form which the Supervisors may approve and must be lodged at the place specified in the notice of the meeting for the lodging of proxies not less than 48 hours before the meeting (or adjourned meeting) at which it is to be used. 104. No business shall be transacted at any meeting of Scheme Creditors unless a quorum is present when the meeting proceeds to business. 20 Scheme Creditors present in person or by proxy and having the right to vote at the meeting shall be a quorum, unless the Supervisors and the Creditors' Committee agree a smaller number. All resolutions put to the vote of any meeting shall be decided on a poll (rather than on a show of hands). 105. One of the Supervisors shall preside (or shall nominate a representative to preside) at each meeting of the Scheme Creditors (other than at a meeting at which a resolution to remove a Supervisor is proposed, when the chairman of the Company shall preside), but if the Supervisor (or his nominated representative) or, if relevant, the chairman of the Company is not present within 30 minutes after the time appointed for opening the meeting or is unwilling to preside, the Scheme Creditors present in person or by proxy shall choose some member of the Creditors' Committee or, if no such member is present or if all such members present decline to preside, one of themselves, to be chairman of the meeting. If no person is willing to preside as chairman of the meeting, the meeting shall be adjourned for seven days, and, if no person is willing to preside as chairman of such meeting reconvened following an adjournment, the meeting shall be dissolved. VALUATION OF SCHEME CLAIMS FOR THE PURPOSES OF MEETINGS 106. For the purposes of valuing any Scheme Claim which a Scheme Creditor has for either of the purposes referred to in sub-clause 93(4) and clause 102, the value of the Scheme Claim shall, in the case of a Scheme Claim which has been Admitted, be the amount of the Admitted Scheme Claim so established (or relevant part thereof) and, in the case of any other Scheme Claim, be such amount as may, for the purposes of such meeting only, be estimated as the value of such Scheme Claim (or relevant part thereof) by the chairman of the meeting. The operation of clause 7 shall not have the effect of extinguishing a Scheme Claim for the purposes of this Part IX. 234

II. THE CORP SCHEME -------------------------------------------------------------------------------- 107. In the event that a Scheme Creditor disputes the value which has been put on its Scheme Claim, pursuant to clause 106 or otherwise, the dispute shall be referred to the President at that time of the Institute of Chartered Accountants in England and Wales (or, if one of the Supervisors or any of their partners at such time occupies such office, the President of the Law Society of England and Wales) or such other individual qualified to act as an insolvency practitioner within the meaning of section 390 of the Insolvency Act 1986 as such President may nominate. Such nominee shall consult with such relevant experts as he thinks appropriate and shall act as an expert not an arbitrator and his decision (including as to who should bear the costs of such referral) shall be final (but only as regards the convening of the meeting or the vote on that occasion). 108. For the purposes of ascertaining whether or not the requisite percentage for the convening of any meeting of Scheme Creditors or the requisite majority at any meeting of Scheme Creditors has been obtained, the amount of each Scheme Claim (or relevant part thereof) which is denominated in a currency other than sterling shall be converted into sterling at the Scheme Rate. 235

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART X TERMINATION 109. This Scheme shall be unaffected by any future liquidation of the Company and shall in those circumstances continue according to its terms. 110. (1) As soon as reasonably practicable after the making of the Final Distribution or the Supervisors' determination that any further distribution of Scheme Consideration (or the distribution of the proceeds of sale of such Scheme Consideration) would be uneconomic, the Supervisors shall serve the Termination Notice on the Company, the members of the Creditors' Committee and the Scheme Creditors. For the avoidance of doubt, the Supervisors shall not direct the Final Distribution (or determine that any further distribution of Scheme Consideration or the proceeds of sale of such Scheme Consideration would be uneconomic) until all Unadmitted Claims have become Admitted or Conclusively Rejected. (2) If the Supervisors, acting reasonably, determine that any further distribution of Scheme Consideration (or the distribution of the proceeds of sale of such Scheme Consideration) would be uneconomic, the remaining Scheme Consideration shall in each case be sold and the net proceeds of sale shall (on behalf of the Scheme Creditors for whose absolute benefit that Scheme Consideration is held under the Escrow and Distribution Agreement) be paid to the Company for its own use and benefit absolutely. (3) For the purposes of clause 110 a distribution shall be uneconomic if the costs of making the distribution would exceed the value of the Scheme Consideration (or proceeds of sale of such Scheme Consideration) to be distributed. 111. With effect from the issue of the Termination Notice: (1) the Scheme Creditors, the Creditors' Committee, the Company, the Supervisors, the Eurobond Trustee, the Yankee Bond Trustee, the Escrow Trustee, the Distribution Agent, the Registrars and Bondholder Communications shall have no further rights and obligations under this Scheme except any rights arising as a result of sub-clause 7(2); and (2) the Supervisors (and any former Supervisors) and the members of the Creditors' Committee (and any former members) shall be discharged from liability for their respective acts, omissions and conduct pursuant to or under the Scheme other than liability arising: (a) in the case of the Supervisors (and any former Supervisors), as a result of their own negligence, default, breach of duty, breach of trust, fraud or dishonesty (or as a result of the negligence, default, breach of duty, breach of trust, fraud or dishonesty of any Employee); and (b) in the case of the members of the Creditors' Committee (and any former members), from loss or damage attributable to its or his own wilful default, fraud, dishonesty or wilful breach of duty. (3) Where a Termination Notice is served pursuant to sub-clause 115(3), so as to bind Scheme Creditors and any person deriving title from them the Supervisors shall direct the Escrow Trustee to transfer, or procure the transfer of, to the Company (or as the Company shall direct) all Scheme Consideration not previously the subject of a Distribution this being done by the Escrow Trustee on behalf of the Scheme Creditors absolutely entitled to such remaining Scheme Consideration. 236

II. THE CORP SCHEME -------------------------------------------------------------------------------- PART XI GENERAL SCHEME PROVISIONS EFFECTIVE TIME AND NOTIFICATION 112. The Company shall give notification of the Scheme having become effective by placing advertisements in The Times and the world-wide editions of the Wall Street Journal, the Financial Times and the International Herald Tribune as soon as reasonably practicable following the occurrence of the Effective Time. COSTS 113. There shall be paid in full by the Company all costs, charges, expenses and disbursements reasonably incurred by the Company in connection with the negotiation, preparation and implementation of the Scheme as and when they arise, including the costs of holding the meeting of Scheme Creditors convened pursuant to the order of the Court to consider the Scheme and the costs of obtaining the sanction of the Court and the costs of placing the notices required by the Scheme. 114. The Company shall pay the costs, charges, expenses and disbursements reasonably incurred by Bondholder Communications, the Escrow Trustee, the Distribution Agent, the Eurobond Trustee, the Yankee Bond Trustee, the security trustee in respect of the New Notes, the Sponsors, the Co-ordination Committee and the Informal Committee of Bondholders and the costs of their respective legal and financial advisors in connection with the negotiation, preparation and implementation of the Scheme and, in the case of Bondholder Communications, also in connection with the negotiation, preparation and implementation of the plc Scheme) including, for the avoidance of doubt, the costs of legal and financial advisers to the Creditors' Committee permitted in accordance with clause 83. 115. (1) For the avoidance of doubt, save as expressly provided in the Scheme, any costs, charges, expenses, remuneration and disbursements which are expressed to be payable by the Company in accordance with the terms of the Scheme (including those provided for in Part VII, VIII and IX and in this Part XI of the Scheme) shall not be paid out of the Scheme Consideration. (2) If at any time in the reasonable opinion of the Supervisors either: (a) the Company is unable to pay in full any sum which is expressed to be payable by the Company in accordance with the provisions of this Scheme; or (b) the Company refuses to pay any sum despite the reasonable efforts of the Supervisors to require payment and it would be materially prejudicial to wait until the Company can be forced to pay it, then (subject to the proviso below) the Supervisors may raise such sum from the Scheme Consideration in any manner in which they think fit and effect the relevant payment on behalf of the Company and in such event: (i) if the event takes place before the expiry of the Waiting Period the Supervisors may take into account the effect of having to raise such sum in such manner in deciding whether or not to bring the Waiting Period to an end; (ii) whenever the event takes place, the Company shall continue to be liable to pay such sum and to reimburse the Escrow Trustee for any such sums raised from Scheme Consideration by the Supervisors pursuant to this clause 115; and (iii) whenever the event takes place, the Creditors' Committee may nominate one of their number to bring proceedings against the Company in the name and on behalf of the Scheme Creditors to oblige the Company to effect such reimbursement, 237

II. THE CORP SCHEME -------------------------------------------------------------------------------- PROVIDED THAT where, and to the extent that, the aggregate of all such sums raised by the Supervisors and not subsequently reimbursed by the Company would exceed L1,500,000, the Supervisors may only raise in excess of that amount with the consent of the Creditors' Committee, such consent not to be unreasonably withheld. (3) If the Creditors' Committee, acting reasonably, withhold giving consent to the Supervisors raising any sums in excess of L1,500,000 pursuant to this clause 115, the Supervisors shall serve a Termination Notice on the Company, the members of the Creditors' Committee and the Scheme Creditors. Clause 111 will thereafter apply. LISTING, CAPITAL REDUCTION AND US REGISTRATION 116. The Company shall, and, as appropriate, shall procure that the relevant bodies corporate within the Marconi Group shall, create and perfect all security referred to at Appendix 10 and execute all documents required to achieve this as soon as practicable on or following the Effective Date. 117. The Company shall use all reasonable endeavours to: (1) procure that Listing of the New Shares, the New Notes and the Warrants takes place as soon as possible on or after the Effective Date and is maintained; and (2) to the extent that the Company wishes to utilise the same, procure that all filings from time to time necessary for the renewed annual listing of the New Notes programme on each 12 month anniversary of the date on which the New Notes programme was first listed with the relevant listing and trading authority are made with the relevant listing and trading authority; (3) effect the listing of the ADRs on NASDAQ as soon as practicable after the Effective Date; (4) reduce its share capital in the manner envisaged in Recital E. 118. The Company shall use its reasonable endeavours to cause a registration statement on Form F-1 to be declared effective under the US Securities Act of 1933 in respect of the Warrants and the ordinary shares of the Company issuable on exercise of the Warrants as soon as practicable following the Effective Date.

II. THE CORP SCHEME -------------------------------------------------------------------------------- SCHEDULE 1 DETERMINATION OF CLAIMS AND PAYMENT OF DIVIDENDS 1. This Schedule applies without prejudice to Parts II, III and IV of the Scheme. If there is any conflict between provisions in this Schedule and provisions set out in the body of the Scheme, the provisions set out in the body of the Scheme shall prevail. 2. For the purposes of determining whether a Scheme Claim should become an Admitted Scheme Claim for the purposes of Distributions, the Insolvency Rules 1986 (the "RULES") listed in this Schedule shall, save where the contrary is stated, be applied in respect of that Scheme Claim and the listed Rules be applied as if: (1) the Company was being wound up voluntarily; (2) the Claim Forms were proofs of debt; (3) the Supervisors were liquidators of the Company; and (4) the references to the date on which a company went into liquidation are to the Record Date (save in the application of Rule 4.92, which shall be amended as set out below). 3. The Rules to be applied are: 4.73(3) meaning of "prove" 4.76 particulars of a creditor's Scheme Claim 4.77(1) claims established by affidavit (save that a statutory declaration may be called for) 4.77(2) affidavit in addition to proof 4.78(1) creditor's cost of proving 4.82 admission and rejection of proofs for dividend 4.86(1) estimates of quantum 4.89 discounts 4.90 mutual credit and set off (save that sub-rule (3) is to be amended by deleting the words "that a meeting of creditors has been summoned under section 98 or (as the case may be) a petition for the winding-up of the company was pending" and replacing them with the words "that a meeting of creditors for the purpose of approving the Scheme had been summoned") 4.91(1) debts in foreign currency (save that it shall be amended by deleting the words "official exchange rate" and replacing them with the words "Scheme Rate" and the words "prevailing on the date when the company went into liquidation" shall be deleted) 4.92 payments of a periodical nature (save that rule (1) is to be amended by deleting the words "date when the company went into liquidation" and replacing them with the words "date on which the Scheme is approved at a creditors' meeting held for that purpose") 4.94 debt payable at future time 11.8 proof altered after payment of dividend (save that an increased proof may be admitted only if the Supervisors in their sole discretion so decide) 11.11 assignment of right to dividend 11.13(1) and (2) debt payable at a future time 4. The English law liquidation rules preventing "double proof" shall apply. 241

II. THE CORP SCHEME -------------------------------------------------------------------------------- SCHEDULE 2 EXTRACT FROM THE PLC SCHEME Capitalised terms in this Schedule shall have the meaning given to them in the plc Scheme. THE COMPANY AS A RECIPIENT OF SCHEME CONSIDERATION FROM THE CORP SCHEME 26. Property received or receivable by the Company from time to time other than the Ancrane Cash Deduction by virtue of the Ancrane Direction shall be available for distribution and shall be distributed by the Company to Admitted Scheme Creditors subject to, at the time, in the manner and on the basis set out in the Scheme. In the light of the position of Corp as a creditor of the Company entitled to participate in distributions under the Scheme and the position of Ancrane as a creditor of Corp and a Bondholder entitled to participate in distributions under the Corp Scheme, this may involve successive distributions between the Company and Corp including distributions made in accordance with the Ancrane Direction, either notional or actual, as provided for in this Scheme and the Corp Scheme. THE CORP/PLC MODEL 27. (1) Sub-clauses 27(2), (3) and (4) shall apply to the Initial Distribution if all of the conditions set out at (a) - (c) inclusive below are satisfied on the Effective Date: (a) the Corp Scheme including provisions in the form or substantially the form of that set out in Schedule 2 becomes effective; (b) the Supervisors admit Corp's Known Claim; and (c) (i) Ancrane's Claim is admitted by the supervisors of the Corp Scheme pursuant to the terms of the Corp Scheme; (ii) either (or both) of the claims of the Eurobond Trustee listed in schedule 3 to the Corp Scheme are admitted by the supervisors of the Corp Scheme pursuant to the terms of the Corp Scheme; or (iii) either (or both) of the claims of the Yankee Bond Trustee listed in schedule 3 to the Corp Scheme are Admitted by the Supervisors of the Corp Scheme pursuant to the terms of the Corp Scheme. (2) To give effect to clause 26 and on the conditions in sub-clause 27(1) being satisfied on the Effective Date, the Supervisors shall agree with the Corp Scheme supervisors a distribution model simulating successive distributions in the Corp Scheme and the Scheme of the amounts distributed to Corp in the Scheme and to the Company (pursuant to the Ancrane Direction) (using the figures for Corp's Known Claim, Ancrane's Claim as actually admitted by the supervisors of the respective Schemes and Ancrane's holding of Bonds) in order to produce a net additional amount of Scheme Consideration available for Distribution to Admitted Scheme Creditors with the Initial Distribution (such net additional amount being the "CORP DISTRIBUTION SUPPLEMENT"). The Corp Distribution Supplement shall be distributed to Eligible Recipients at the times and in the manner set out in sub-clause 27(4). (3) The Elements of the Corp Distribution Supplement shall for these purposes be treated as being made up of two parts as follows: (a) the "KNOWN CLAIMS SUPPLEMENT" which shall be the Corp Distribution Supplement less the Reserve Claims Supplement; and (b) the "RESERVE CLAIMS SUPPLEMENT" which shall be the same proportion of the Corp Distribution Supplement as the Basic Reserve Claims Segment (which for this purpose shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected which results in the 242

II. THE CORP SCHEME -------------------------------------------------------------------------------- Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29) is of the Basic Scheme Consideration. (4)(a) The Elements of the Known Claims Supplement shall be distributed to Admitted Known Creditors at the same time as the Initial Distribution. (b) The Elements of the Reserve Claims Supplement shall be distributed to Admitted Reserve Creditors at the same time as the Initial Distribution. (5)(a) For the purposes of Distributions under the Scheme: (i) other than the Initial Distribution; and/or (ii) as regards the Initial Distribution if the provisions of sub-clauses 27(2)-27(4) inclusive do not come into force because one or more of the conditions in sub-clause 27(1) is not satisfied, the Supervisors may agree similar or analogous arrangements to those in sub-clauses 27(2) (a "MODEL") with the supervisors of the Corp Scheme where, acting reasonably, the Supervisors consider that to do so will be in the interests of Admitted Scheme Creditors. (b) If a model is agreed pursuant to sub-clause 27(5)(a) prior to the expiry or termination of the Waiting Period, the equivalent of the Corp Distribution Supplement thereby created shall be apportioned in the same manner as provided for in sub-clause 27(3), otherwise no apportionment shall be made. (c) Any supplement arising pursuant to sub-clause 27(5)(a)(ii) which shall be apportioned in accordance with sub-clause 27(5)(b) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (d) Any supplement arising pursuant to sub-clause 27(5)(a)(i) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 27(5)(b) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (e) Any supplement arising pursuant to sub-clause 27(5)(a)(i) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. CORP RECEIPTS 28. (1) As regards: (a) the Initial Distribution if the provisions of sub-clauses 27(2)-27(4) above do not come into force for any reason; and (b) any Distributions other than the Initial Distribution, in each case, to the extent that relevant similar or analogous arrangements as referred to in clause 27(5) are not agreed in respect of the Company's entitlement to the Corp Receipts, Admitted Scheme Creditors shall be entitled to all Corp Receipts from time to time which shall be held on trust for Scheme Creditors under the Scheme. 243

II. THE CORP SCHEME -------------------------------------------------------------------------------- (2) If Corp Receipts arise pursuant to sub-clause 28(1) prior to the expiry or termination of the Waiting Period, those Corp Receipts shall be apportioned in the same manner as provided for in sub- clause 27(3), otherwise no apportionment shall be made. (3) Any Corp Receipts arising pursuant to sub-clause 28(1)(a) which shall be apportioned in accordance with sub-clause 28(2) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (4) Any Corp Receipts arising pursuant to sub-clause 28(1)(b) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 28(2) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (5) Any supplement arising pursuant to sub-clause 28(1)(b) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. 244

II. THE CORP SCHEME -------------------------------------------------------------------------------- SCHEDULE 3 KNOWN CLAIMS Following is a list of Scheme Creditors who may have a Scheme Claim. The fact that a claim listed below has been provided for in this Schedule 3 at a certain amount does not mean that the particular claim shall be Admitted at that, or any other, amount. The column headed "Claimed/Estimated Value (including accrued interest) in L's as at the Record Date" provides an indicator of the amount for which each claim may be admitted for the purposes of voting at the meeting of Scheme Creditors convened at the direction of the Court (subject to the remarks set out in the "Remarks" columns). Where necessary, to calculate the Claimed/Estimated Value of a claim in sterling, the Exchange Rate on the Business Day falling immediately prior to the Record Date has been applied if necessary. <Table> <Caption> AMOUNT TOTAL AMOUNT CLAIMED/ESTIMATED CLAIMED/ESTIMATED VALUE (INCLUDING VALUE (INCLUDING ACCRUED INTEREST) ACCRUED INTEREST) AS AT IN L'S AS AT CREDITOR THE RECORD DATE THE RECORD DATE REMARKS -------- ------------------- ----------------- -------------- <S> <C> <C> <C> SYNDICATED BANK DEBT ABN Amro Bank NV US$47,226,487 L43,932,580 L13,920,832 Appaloosa Investment Ltd Partnership US$227,732,619 L221,266,466 L76,545,686 Australia and New Zealand Investment Bank US$91,430,478 L85,053,475 L26,950,731 Banca Antoniana Popolare Veneta London US$7,556,238 L7,029,213 L2,227,333 Banca Monte dei Paschi di Siena US$47,226,487 L43,932,580 L13,920,832 Banca Nazionale del Lavoro SpA US$78,868,233 L73,367,409 L23,247,790 Banca Popolare di Lodi US$15,584,741 L14,497,751 L4,593,875 Banco di Roma US$39,670,249 L36,903,367 L11,693,499 Bank of America N.A.

Note 5: This includes Millionerrors Investment Club, Mr GG Griwatz, Mr PE Graham, Mr JP Iurlano, Mr J Krim, Mr M Winick, R.S. Harman & Co., G Dirienzo and the class of plaintiffs they represent. Note 6: The amount allegedly due to such creditors cannot be estimated, as there is a dispute between the Company and the Scheme Creditor as to the whole of the amount claimed. However, the amount claimed by the Scheme Creditor from the Company is shown in brackets for information only. If a Scheme Claim is disputed in its entirety, whether it is liquidated or unliquidated, the chairman will not admit it for the purpose of voting on the Scheme. The chairman's decision will be final. The chairman will, however, advise the relevant Scheme Creditor of his decision to reject such Scheme Creditor's claim for voting purposes before the Scheme Meeting if he considers it to be practicable and, in any event, at or after the Scheme Meeting, and report his decision to the Court. Note 7: The amount due to this creditor cannot be estimated, as there is a dispute between the Company and the Scheme Creditor as to the whole of the amount claimed. The Scheme Creditor claims certain unspecified amounts and has not provided a total figure that it alleges the Company owes to it. The amount estimated by the Company to be a prudent figure for the claim based on other claims of a similar nature is shown in brackets for information only. If a Scheme Claim is disputed in its entirety, whether liquidated or unliquidated, the chairman will not admit it for the purpose of voting on the Scheme. The chairman's decision will be final. The chairman will, however, advise the relevant Scheme Creditor of his decision to reject such Scheme Creditor's claim for voting purposes before the Scheme Meeting if he considers it to be practicable and, in any event, at or after the Scheme Meeting, and report his decision to the Court. Note 8: Such Scheme Creditors will not be voting at the Court sanctioned creditors' meeting as they are connected creditors, related to either Corp or plc. Even though these creditors will not vote, they agree to support the Restructuring by agreeing not to take any action to hinder or oppose the Schemes and not to seek to challenge either Scheme in the courts of any jurisdiction. Note 9: Ancrane also holds US$131,011,000 of the US$900,000,000 7 3/4 per cent. bonds due 2010; US$130,090,000 of the US$900,000,000 8 3/8 per cent. bonds due 2030; E256,735,000 of the E1,000,000,000 6.375 per cent. bonds due 2010; and E67,868,000 of the E500,000,000 5.625 per cent. bonds due 2005 (see Notes 1 to 4 above). Accordingly, Ancrane's aggregate claim against Corp (converted into sterling as at the Record Date) is approximately L776 million. </Table> 249

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART II THE SCHEME APPLICATION AND EFFECTIVENESS OF THE SCHEME 1. (1) The compromise and arrangement effected by the Scheme shall apply to all Scheme Claims and shall be binding on all Scheme Creditors. (2) The Scheme is conditional upon the Corp Scheme becoming effective and the office copy of the order of the Court sanctioning the Scheme will not be filed with the Registrar of Companies unless and until the Corp Scheme has become effective. (3) The Scheme shall become effective at the Effective Time provided always that the Effective Time. (4) The Company shall forthwith after the Effective Time declare that it holds: (a) all its assets (except the shares in the capital of Ancrane, the Basic Scheme Consideration and the Expenses Fund) on bare trust absolutely to be transferred on the direction of the Supervisors to the Escrow Trustee to hold on trust in accordance with the Escrow and Distribution Agreement; and (b) the Expenses Fund on trust for itself absolutely but for the purposes only of: (i) first, meeting or providing for Scheme Expenses and Excluded Claims in accordance with the Scheme; and (ii) secondly, paying Corp an amount equal to the amount paid by Corp under the LC Counter-Indemnity; and (iii) thirdly, transferring any balance remaining in the Expenses Fund immediately prior to the Final Distribution to the Escrow Trustee to hold on trust in accordance with the terms of the Escrow and Distribution Agreement. (5) Forthwith after the Effective Time the Supervisors shall set the Unclaimed Dividends Fund aside from the Expenses Fund to be held on trust for the purposes of paying Unclaimed Dividends and dealt with in accordance with the Scheme (including, without limitation, clause 112). STAY OF PROHIBITED PROCEEDINGS 2. (1) Subject to sub-clause 2(2), no Scheme Creditor shall commence or continue any Prohibited Proceeding in respect of, arising from, or relating to, a Scheme Claim after the Effective Time. (2) Nothing in this Scheme shall prevent: (a) a landlord of leasehold property of the Company from exercising such rights and remedies of distress, forfeiture and re-entry (and any other of such landlord's self-help rights and remedies) as it may have in respect of such leasehold property; or (b) a secured creditor from exercising its rights and remedies as a secured creditor in respect of any Property of the Company. 3. Subject to sub-clause 20(2), a Scheme Creditor may commence or continue an Allowed Proceeding against the Company after the Effective Time provided that it has first: (1) where the Scheme Creditor is continuing an Allowed Proceeding, notified the Supervisors in writing of its intention to do so; (2) where the Scheme Creditor intends to commence an Allowed Proceeding, given the Supervisors five Business Days' prior notice in writing of its intention to do so; and 268

III. THE PLC SCHEME -------------------------------------------------------------------------------- (3) where sub-clause 17(2) applies with respect to an Allowed Proceeding, it has, in addition to complying with sub-clause 3(1) or 3(2), as applicable complied with that sub-clause. 4. (1) Save in respect of any Allowed Proceeding as permitted by this Scheme or any action permitted under sub-clause 2(2), each Scheme Creditor by this Scheme covenants not to sue the Company in respect of a Scheme Claim. (2) For the purpose of enforcing the covenant in sub-clause 4(1), the Company is hereby appointed as the agent and attorney of each and every Scheme Creditor for the purpose of giving any and all instructions (and doing any such acts or things) as are necessary or desirable to enforce that covenant. 5. If any Scheme Creditor commences or continues any such Prohibited Proceeding as is prohibited by sub-clause 2(1) after the Effective Time it shall be treated as having received, on account of its entitlement to Scheme Consideration, an advance payment by way of a Distribution equal to the amount or gross value of any money, property, benefit or advantage obtained by it after the Effective Date at the expense of the Company or, as applicable, as a result, directly or indirectly, of such Prohibited Proceeding, and the extent, if any, to which it is entitled to Scheme Consideration shall be reduced accordingly. Such Scheme Creditor shall hold any benefit received or receivable in excess of its entitlement to Scheme Consideration pursuant to the terms of the Scheme as a result, directly or indirectly, of a Prohibited Proceeding on trust for the Company and shall account to the Company for such excess benefit. For this purpose, the gross value of any such property, benefit or advantage shall be conclusively determined by the Supervisors and may include such amount as the Supervisors may consider to be appropriate by way of interest or costs, charges or expenses incurred by the Company and/or the Supervisors as the result of such Prohibited Proceeding. This treatment and reduction is without prejudice to the Company's rights first to any injunctive or other relief or remedy to which the Company may be entitled in respect of the breach and, secondly, in respect of any loss the Company may suffer as a result of the breach. The Supervisors shall make such consequential adjustments to the amount and timing of payment of Distributions to any such Scheme Creditor (and in the case of Definitive Bondholders, to the Eurobond Trustee or the Yankee Bond Trustee or both as appropriate) pursuant to the rules and formulae in Part III as are necessary to give effect to this clause. ASSIGNMENTS OR TRANSFERS 6. (1) The Supervisors shall be under no obligation to recognise any assignment or transfer of Scheme Claims after the Record Date for the purposes of determining entitlements under the Scheme, provided that where the Supervisors have received from the relevant parties notice in writing of such assignment or transfer, the Supervisors may, in their sole discretion and subject to the production of such other evidence as they may require and to any other terms and conditions which they may consider necessary or desirable, agree to recognise such assignment or transfer for the purposes of determining entitlements under the Scheme. Any assignee or transferee of a Scheme Claim so recognised by the Supervisors shall be bound by the terms of this Scheme and for the purposes of this Scheme shall be a Scheme Creditor. (2) For the purposes of the Scheme (including for the purposes of the definition of Excluded Claims) no recognition shall be given to any assignment or transfer of any (or any part of any) debt, claim or right of any person in respect of a Liability of the Company effected between 1 January 2003 and the Record Date (both dates inclusive) other than any such assignment or transfer pursuant to or contemplated by the Scheme Implementation Deed if, in the reasonable opinion of the Supervisors, a material purpose of such assignment or transfer was to make such debt, claim or right (or part thereof) an Excluded Claim (under sub-paragraph (8) of the definition of Excluded Claims) and not a Scheme Claim. (3) For the avoidance of doubt, in relation to the Bonds, Bondholders are permitted to assign or transfer their interest in Bonds after the Record Date. 269

III. THE PLC SCHEME -------------------------------------------------------------------------------- EFFECT OF SCHEME 7. (1) This clause is without prejudice to the Company's rights under clauses 2 and 5 and is subject to Part IX. (2) Without prejudice to clause 20, in consideration of the rights of Scheme Creditors under this Scheme (including the rights of Admitted Scheme Creditors to receive Scheme Consideration), all Liabilities on the part of the Company in respect of each Scheme Claim (and any interest accruing thereon or other amounts payable in connection therewith whether arising before or after the Record Date), automatically and without further documentation or action of the parties, shall be compromised, fully and finally discharged, satisfied and cancelled on the earlier of: (a) the first date on which such Scheme Claim is both Admitted and the subject of a Distribution Notice; (b) the Final Distribution Date; and (c) the issue of the Termination Notice (other than a Termination Notice served pursuant to sub-clause 117(3)). (3) No Scheme Claim of a Scheme Creditor shall be reduced or in any way affected by the compromise of any claims of that Scheme Creditor against Corp pursuant to the terms of the Corp Scheme nor shall it be reduced or in any way affected by reason of any distributions received by or on behalf of that Scheme Creditor in the Corp Scheme provided that the aggregate recoveries of a Scheme Creditor in respect of a claim pursuant to the Scheme and the Corp Scheme shall not exceed the quantum of the Scheme Claim. (4) Nothing in sub-clause 7(2) shall operate to discharge or release the Company from any Liability to a Scheme Creditor to the extent to which that Liability would constitute an Insured Scheme Claim until all monies due to the Scheme Creditor pursuant to clause 31 in satisfaction of that Insured Scheme Claim have been paid. 270

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART III DETERMINATION OF SCHEME CLAIMS AND PROCEDURE FOR DISTRIBUTIONS RECORD DATE 8. (1) All Scheme Claims shall be determined as at the Record Date. (2) Any Scheme Claim which at the Record Date is not immediately due and payable but on the Company going into insolvent liquidation would, either automatically without further action by any party or by the issue of a notice by the relevant Scheme Creditor, be capable of being made legally and immediately due and payable shall be treated for the purposes of Distributions under this Scheme as immediately due and payable as at the Record Date (and hence not a debt payable at a future time). RULES AND PROCEDURES 9. The Supervisors shall consider each Claim Form submitted to determine the existence and quantum of each Submitted Scheme Claim and shall decide the extent, if any, to which it shall be Admitted in accordance with the rules and procedures set out in the Scheme and in particular in Schedule 1. ONLY ADMISSIBLE INTEREST 10. Without prejudice to sub-clause 7(2), for the purpose solely of the determination and payment of Distributions under the Scheme, no Admitted Scheme Claim shall include any amounts in respect of interest except Admissible Interest and, for the avoidance of doubt, any interest other than Admissible Interest shall not be taken into account by the Supervisors in determining the quantum of the relevant Scheme Claim. NO ADMISSIONS OF LIABILITY 11. Save as expressly set out in this Scheme or the Explanatory Statement nothing in the Scheme or the Explanatory Statement or the distribution thereof to any person evidences or constitutes any admission by the Company, the Prospective Supervisors, the Supervisors or KPMG that a person is a Scheme Creditor or that a Liability is owed to any person in respect of any claim or right. The failure to distribute the Scheme, Explanatory Statement, any notice or any other communication to any Scheme Creditor shall not constitute an admission by the Company, the Prospective Supervisors, the Supervisors or KPMG that such person is not a Scheme Creditor or that any Liability owed to such person is an Excluded Claim. PROVISION OF INFORMATION 12. (1) A Scheme Creditor submitting a Scheme Claim: (a) shall provide the Supervisors with such information as they may reasonably require to enable the claim to be determined (and for the avoidance of doubt shall comply with such of the rules and procedures in Schedule 1 as the Supervisors may require); and (b) shall, in any event, submit a Claim Form to the Prospective Supervisors or, after the Effective Date, to the Supervisors (in accordance with the instructions set out in the Claim Form) at the relevant address set out in the Claim Form by hand or by Post. (2) Scheme Creditors who wish an Initial Distribution to be distributed to the Eligible Recipient in respect of that Scheme Creditor's Scheme Claim on the Effective Date must have submitted their duly completed Claim Forms so as to be received by the Prospective Supervisors by 5.00 p.m. (London time) on the First Claim Date. Only Known Creditors that have complied with this precondition and whose Scheme Claims are listed in the First Initial Distribution Notice shall be Admitted by the Supervisors in accordance with the Scheme on the Effective Date and participate in the First Initial Distribution in accordance with clause 23. Only if a Scheme Creditor has 271

III. THE PLC SCHEME -------------------------------------------------------------------------------- complied with this pre-condition and its Scheme Claim is Admitted by the Supervisors in accordance with the Scheme on the Effective Date shall that Admitted Scheme Creditor's Eligible Recipient receive an Initial Distribution when the First Initial Distribution is made. (3) For the purposes of this Scheme, it is expressly recognised that: (a) the Eurobond Trustee shall be entitled to submit a Claim Form in its capacity as creditor under the Trust Deeds in respect of all of the Eurobonds and, in consequence, no person with an interest in the Eurobonds other than the Eurobond Trustee shall be entitled to submit a Claim Form in respect of the Eurobonds by virtue of such interest; and (b) the Yankee Bond Trustee shall be entitled to submit a Claim Form in accordance with section 5.04 of the Indenture and, in consequence, no person with an interest in a Yankee Bond other than the Yankee Bond Trustee shall be entitled to submit a Claim Form in respect of the Yankee Bonds by virtue of such interest. ENTITLEMENT TO SCHEME CONSIDERATION 13. Eligible Recipients shall be eligible to receive Scheme Consideration in accordance with the Scheme. A Scheme Creditor with a Scheme Claim which is Unadmitted shall not be entitled to Scheme Consideration in accordance with the Scheme unless, until and to the extent that such Scheme Claim becomes Admitted. 14. The amount of the Scheme Consideration to which a Scheme Creditor is entitled (and any Eligible Recipient in respect of that Scheme Creditor's Admitted Scheme Claim is eligible to receive) shall be calculated in accordance with this Part III. ADMISSION AND REJECTION OF SCHEME CLAIMS 15. A Scheme Claim may be Admitted by the Supervisors either for the whole amount claimed by the Scheme Creditor or for part of that amount. 16. If the Supervisors refuse to admit a Scheme Claim, in whole or in part, they shall promptly prepare a written statement of their reasons for doing so, and send it to the Scheme Creditor, accompanied by a notice of rejection in such form as the Supervisors shall determine. APPEAL AGAINST DECISION ON SCHEME CLAIMS 17. (1) If a Scheme Creditor is dissatisfied with a refusal by the Supervisors to admit, in whole or in part, a Scheme Claim then, subject to sub-clause 17(2), it may either commence or continue an Allowed Proceeding to determine the existence and/or quantum of its Scheme Claim or elect by notice in writing to the Supervisors that the existence or quantum of its Scheme Claim be referred for adjudication in accordance with Part V. (2) If an Allowed Proceeding has not been commenced, or is not being continued as at the date of the notice of rejection, then either: (a) an Allowed Proceeding must be commenced (and notice given in accordance with clause 3); or (b) an election for adjudication made in accordance with sub-clause 17(1) by the Scheme Creditor, in each case within 40 Business Days following receipt by the Scheme Creditor of the notice of rejection. 18. If a Scheme Claim has not been Admitted and at the expiration of the 40 Business Days period referred to in sub-clause 17(2) an Allowed Proceeding is continuing (whether commenced by the Scheme Creditor 272

III. THE PLC SCHEME -------------------------------------------------------------------------------- before or after receipt of the notice of rejection) or an election has been made for adjudication (in each case in accordance with clause 17) then: (1) any final determination of that Allowed Proceeding (after the ordinary time for appealing the original determination or any determination on appeal has expired without any appeal having been made) shall be binding on the Scheme Creditor, the Company and the Supervisors; (2) if an election has been made for adjudication the provisions of Part V shall apply; and (3) without prejudice to sub-clauses 18(1) and 18(2), the Scheme Creditor and the Supervisors may at any time agree to any matter or issue in the Allowed Proceeding being determined in some manner other than in the Allowed Proceeding, and any Proceeding commenced pursuant to such agreement shall have effect as an Allowed Proceeding commenced in accordance with clause 17. 19. If in an Allowed Proceeding or in an adjudication pursuant to Part V any order or direction shall be made that any costs of such proceeding or adjudication are to be borne by the Supervisors or by the Company, such costs shall be payable in full from the Expenses Fund. 20. If a Scheme Claim has not been Admitted and at the expiration of the 40 Business Days period referred to in sub-clause 17(2) neither an Allowed Proceeding (in accordance with the terms of the Scheme) is continuing in respect of such Scheme Claim nor an election (in accordance with the terms of the Scheme) has been made for that Scheme Claim to be referred to adjudication in accordance with Part V, then: (1) the Company shall be released from all Liabilities in relation to the Scheme Claim (or part thereof) which has not been Admitted (and any interest accruing thereon or other amounts payable in connection therewith whether arising before or after the Record Date); and (2) any Proceeding which is thereafter commenced and which would otherwise have been an Allowed Proceeding shall be a Prohibited Proceeding. THE BASIC SCHEME CONSIDERATION, THE KNOWN CLAIMS SEGMENT AND THE RESERVE CLAIMS SEGMENT 21. (1) In the Scheme "BASIC SCHEME CONSIDERATION" means the Received Ancrane Consideration minus an amount of L7,000,000 deducted from the Received Ancrane Cash. The amount so deducted from the Received Ancrane Cash (in the Scheme called the "ANCRANE CASH DEDUCTION") shall form part of the sum initially comprising the Expenses Fund. The Expenses Fund, other than the sum comprising the Unclaimed Dividends Fund, shall be available for the settlement or payment of such of the Liabilities of the Company in respect of Excluded Claims and Scheme Expenses as the Supervisors from time to time shall direct. (2) In this Scheme: (a) the term "BASIC KNOWN CLAIMS SEGMENT" means that part of the Basic Scheme Consideration calculated by applying the fraction: <Table> <S> <C> KC ---------------- 250,000,000 + KC </Table> to each Element of Basic Scheme Consideration, where KC = the aggregate amount of the Known Claims; and (b) the term "BASIC RESERVE CLAIMS SEGMENT" means that part of the Basic Scheme Consideration calculated by applying the fraction: <Table> <S> <C> 250,000,000 ---------------- 250,000,000 + KC </Table> to each Element of Basic Scheme Consideration, where KC = the aggregate amount of the Known Claims. 273

III. THE PLC SCHEME -------------------------------------------------------------------------------- (3) In the Scheme: (a) the term "KNOWN CLAIMS SEGMENT" means that part of the Scheme Consideration available until the expiry or termination of the Waiting Period from which Distributions of Distribution Entitlements of Admitted Known Creditors shall be made being, from time to time, the aggregate of the following: (i) the Basic Known Claims Segment; (ii) any Known Claims Supplement arising under sub-clause 27(3) (or equivalent supplement pursuant to sub-clause 27(5)); and (iii) any Corp Receipts made available to Known Creditors as a result of the operation of clause 28. The parts of the Known Claims Segments listed in (ii) and (iii) above shall be treated for all purposes as a supplement to the Basic Known Claims Segment. Any entitlement to receive a distribution from the Basic Known Claims Segment shall be supplemented by an entitlement to receive a distribution of those other parts (if any) of the Known Claims Segment of the same proportion as the Distribution Entitlement of the relevant Scheme Creditor to the Basic Known Claims Segment is of the Basic Known Claims Segment (but such proportion shall be calculated after taking into account any decrease in the size of the Basic Known Claims Segment resulting from Known Claims being Conclusively Rejected which results in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29); (b) the term "RESERVE CLAIMS SEGMENT" means that part of the Scheme Consideration available until the expiry or termination of the Waiting Period from which Distributions of Distribution Entitlements of Admitted Reserve Creditors shall be made being, from time to time, the aggregate of the following: (i) the Basic Reserve Claims Segment; (ii) any Reserve Claims Supplement arising under sub-clause 27(3) (or equivalent supplement pursuant to sub-clause 27(5)); and (iii) any Corp Receipts made available to Reserve Creditors as a result of the operation of clause 28. The parts of the Reserve Claims Segment listed in (ii) and (iii) above shall be treated for all purposes as a supplement to the Basic Reserve Claims Segment and any entitlement to receive a distribution from the Basic Reserve Claims Segment shall be supplemented by an entitlement to receive a distribution of those other parts (if any) of the Reserve Claims Segment of the same proportion as the Distribution Entitlement of the relevant Scheme Creditor to the Basic Reserve Claims Segment is of the Basic Reserve Claims Segment (but such proportion shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected which results in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29). 22. If a Known Claim is Admitted at a value higher than the value of that Known Claim set out in Schedule 3, the excess over the value set out in Schedule 3 shall be treated as an Admitted Reserve Claim. INITIAL DISTRIBUTION AND FIRST INITIAL DISTRIBUTION 23. (1) Each Scheme Creditor who has a Submitted Scheme Claim which is Admitted before the expiry or termination of the Waiting Period shall be entitled to receive an Initial Distribution from: 274

III. THE PLC SCHEME -------------------------------------------------------------------------------- (a) the Known Claims Segment if its Admitted Scheme Claim is a Known Claim; or (b) the Reserve Claims Segment if its Admitted Scheme Claim is a Reserve Claim. This Distribution shall be by way of an in specie distribution of the Basic Scheme Consideration. (2) The Supervisors shall use reasonable endeavours to determine promptly whether or not a Submitted Scheme Claim shall be Admitted and, if they do so determine, shall promptly Admit that Submitted Scheme Claim. (3) As soon as reasonably practicable after a Scheme Claim has been Admitted it shall be the subject of a Distribution Notice. (4) On the Effective Date (a) Known Creditors whose Scheme Claims are Submitted on or before 5.00 p.m. (London time) on the First Claim Date and which have been listed in the First Initial Distribution Notice shall be Admitted by the Supervisors; (b) the Supervisors shall issue the First Initial Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent); (c) Scheme Creditors whose Scheme Claims are Submitted on or before 5.00 p.m. (London time) on the First Claim Date which are Admitted by the Supervisors on the Effective Date but which were not listed in the First Initial Distribution Notice shall be the subject of a Distribution Notice issued by the Supervisors to the Escrow Trustee (with a copy to the Distribution Agent) at the same time as the First Initial Distribution Notice; and (d) Scheme Creditors with Admitted Scheme Claims listed in the First Initial Distribution Notice or any Distribution Notice issued pursuant to sub-clause 23(4)(c) shall be entitled to an Initial Distribution forthwith upon the issue of the First Initial Distribution Notice (and any Distribution Notice issued pursuant to sub-clause 23(4)(c)) in respect of such Admitted Scheme Claim and its Initial Distribution shall be made to its Eligible Recipient. (5) Scheme Creditors whose Scheme Claims are Submitted and which are Admitted before the expiry or termination of the Waiting Period but in respect of which a First Initial Distribution pursuant to sub-clause 23(4)(b) or an Initial Distribution pursuant to sub-clause 23(4)(c) is not made shall be entitled to an Initial Distribution in respect of such Admitted Scheme Claims and such distributions shall be made to their Eligible Recipients as soon as practicable after such claims have been Admitted. (6) The amount of the Initial Distribution (including, for the avoidance of doubt, the First Initial Distribution) from the Known Claims Segment to which an Admitted Known Creditor is entitled shall be calculated in accordance with the following formula: <Table> <S> <C> <C> AKC KDE = KC X KCS </Table> <Table> <S> <C> <C> Where KDE = the Distribution Entitlement of the relevant Admitted Known Creditor to each of the Elements of the Basic Scheme Consideration in the Initial Distribution; AKC = the Admitted Known Claim of the relevant Admitted Known Creditor; KC = the aggregate amount of all Known Claims; and KCS = separately, the amount of each of the Elements of the Basic Scheme Consideration comprising the Basic Known Claims Segment as at the Effective Time. </Table> 275

III. THE PLC SCHEME -------------------------------------------------------------------------------- (7) The amount of the Initial Distribution from the Reserve Claims Segment to which an Admitted Reserve Creditor is entitled shall be calculated in accordance with the following formula: <Table> <S> <C> <C> ARC RDE = --- X KCS KC </Table> <Table> <S> <C> <C> where RDE = the Distribution Entitlement of the relevant Admitted Reserve Creditor to each of the Elements of the Basic Scheme Consideration in the Initial Distribution; ARC = the Admitted Reserve Claim of the relevant Admitted Reserve Creditor; KC = the aggregate amount of all Known Claims; and KCS = separately, the amount of each of the Elements of the Basic Scheme Consideration comprising the Basic Known Claims Segment as at the Effective Time. </Table> (8) Any Distribution Notice given by the Supervisors to the Escrow Trustee (with a copy to the Distribution Agent) shall instruct the Escrow Trustee to direct the Distribution Agent to make a Distribution to all relevant Eligible Recipients referred to in the Distribution Notice in accordance with the terms of the Scheme. (9) Where in sub-clauses 21(2), 23(6) and 23(7) above any sum included in any of the terms AKC, KC and ARC is in a currency other than sterling then, for the purposes of calculating the relevant fraction, that sum shall be converted to sterling at the Scheme Rate. (10) In the case of a Scheme Claim in respect of Bonds which is Admitted where the aggregate total of all Distributions to Designated Recipients in respect of that claim is less, then the Distribution to which the Eurobond Trustee or the Yankee Bond Trustee, as appropriate, in respect of that claim is entitled, the remainder of the Scheme Consideration shall be held by the Escrow Trustee and dealt with in accordance with the Escrow and Distribution Agreement. TERMINATION OF THE WAITING PERIOD 24. (1) Subject to sub-clause 24(2), if at any time after the issue of the First Initial Distribution Notice the Supervisors are not satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted, the following shall apply: (a) the Supervisors shall forthwith notify the Company and the Creditors' Committee; (b) the Waiting Period shall terminate and all entitlements of Admitted Scheme Creditors to Scheme Consideration which have not been the subject of a Distribution Notice shall be dealt with in accordance with the provisions of clause 25; and (c) for the avoidance of doubt, the provisions of this clause shall not affect the Distribution Entitlement of any Scheme Creditor whose Admitted Scheme Claim is the subject of a Distribution Notice issued prior to the issue of the Supervisors' notice in sub-clause 24(1)(a). (2) If a Scheme Claim is Submitted after the issue of the First Initial Distribution Notice which: (a) if immediately Admitted would result in the Supervisors not being satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted; and (b) the Supervisors cannot immediately determine whether, or the extent to which, that Submitted Scheme Claim should be Admitted, the Supervisors may consider that Scheme Claim for a period of up to 30 Business Days from the date on which that Scheme Claim is Submitted (the "EXAMINATION PERIOD"). The Supervisors shall forthwith notify the Company and the Creditors' Committee of the commencement of the 276

III. THE PLC SCHEME -------------------------------------------------------------------------------- Examination Period. On, or prior to, the expiry of such 30 Business Days the Supervisors shall confirm to the Creditors' Committee and the Company whether or not they are satisfied that the Reserve Claims Segment shall be sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted. The issue of the Supervisors' confirmation or, if later, the expiry of the 30 Business Day period shall bring the relevant Examination Period to an end. If no confirmation is provided prior to the expiry of such 30 Business Days, the Supervisors are deemed to be not satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted. If the Supervisors are (or are deemed to be) not satisfied that the Reserve Claims Segment is sufficient to make Distributions of Distribution Entitlements in respect of all Reserve Claims which have been, or are likely to be, Admitted, sub-clauses 24(1)(a)-(c) shall apply. No Distribution Notice shall be issued during an Examination Period. For the avoidance of doubt, nothing in this sub-clause shall affect the Distribution Entitlement of any Scheme Creditor whose Admitted Scheme Claim has, prior to the commencement of the Examination Period, been the subject of a Distribution Notice. FURTHER DISTRIBUTIONS 25. (1) Any Scheme Consideration which has not been the subject of a Distribution Notice by the termination or expiry of the Waiting Period shall, from the termination or expiry of the Waiting Period, be available for making further Distributions to Eligible Recipients on the following basis: (a) the distinction between the Known Claims Segment and the Reserve Claims Segment shall no longer be relevant and the remainder of the segments shall be aggregated for future Distribution purposes; (b) the Supervisors' approach to further Distributions shall be in accordance with the approach a liquidator would take following Liquidation Distribution Principles including the following concepts: (i) the setting of final dates by which a creditor must claim if it wishes to participate in a planned dividend; (ii) in the case of claims which have not been Admitted at the time of the declaration of a dividend to creditors, the taking into account of any such disputed claim in setting the dividend on a prudent basis so that if the disputed claim is later admitted, the relevant creditor will receive the dividend it would have received if and to the extent its claim had been admitted at the date of the relevant dividend; (iii) generally, the concept of pari passu distribution; and (iv) any Scheme Creditor whose Scheme Claim is Admitted but whose Distribution Entitlement has not yet been satisfied shall be entitled to a Distribution in priority to the entitlement of other Admitted Scheme Creditors (whose entitlements to previous Distributions have been satisfied) to further Distributions until that Scheme Creditor is entitled to (and such entitlement is satisfied) the same rateable Distribution that other Admitted Scheme Creditors are entitled to (which entitlements have been satisfied) have received previously. (2) The Supervisors, in deciding whether and, if so, when to direct a further Distribution, shall have regard to the cost of making the Distribution in relation to the value of the Scheme Consideration to be distributed and may, acting reasonably, decide to delay directing a Distribution until such time (if any) as the costs of making the Distribution do not exceed the value of Scheme Consideration (or proceeds of sale of such Scheme Consideration) to be distributed. 277

III. THE PLC SCHEME -------------------------------------------------------------------------------- THE COMPANY AS A RECIPIENT OF SCHEME CONSIDERATION FROM THE CORP SCHEME 26. Property received or receivable by the Company from time to time other than the Ancrane Cash Deduction by virtue of the Ancrane Direction shall be available for distribution and shall be distributed by the Company to Admitted Scheme Creditors subject to, at the time, in the manner and on the basis set out in the Scheme. In the light of the position of Corp as a creditor of the Company entitled to participate in distributions under the Scheme and the position of Ancrane as a creditor of Corp and a Bondholder entitled to participate in distributions under the Corp Scheme, this may involve successive distributions between the Company and Corp including distributions made in accordance with the Ancrane Direction, either notional or actual, as provided for in this Scheme and the Corp Scheme. THE CORP/PLC MODEL 27. (1) Sub-clauses 27(2), (3) and (4) shall apply to the Initial Distribution if all of the conditions set out at (a) - (c) inclusive below are satisfied on the Effective Date: (a) the Corp Scheme including provisions in the form or substantially the form of that set out in Schedule 2 becomes effective; (b) the Supervisors admit Corp's Known Claim; and (c) (i) Ancrane's Claim is admitted by the supervisors of the Corp Scheme pursuant to the terms of the Corp Scheme; or (ii) either (or both) of the claims of the Eurobond Trustee listed in schedule 3 to the Corp Scheme are admitted by the supervisors of the Corp Scheme pursuant to the terms of the Corp Scheme; or (iii) either (or both) of the claims of the Yankee Bond Trustee listed in schedule 3 to the Corp Scheme are Admitted by the Supervisors of the Corp Scheme pursuant to the terms of the Corp Scheme. (2) To give effect to clause 26 and on the conditions in sub-clause 27(1) being satisfied on the Effective Date, the Supervisors shall agree with the Corp Scheme supervisors a distribution model simulating successive distributions in the Corp Scheme and the Scheme of the amounts distributed to Corp in the Scheme and to the Company (pursuant to the Ancrane Direction) (using the figures for Corp's Known Claim, Ancrane's Claim as actually admitted by the supervisors of the respective Schemes and Ancrane's holding of Bonds) in order to produce a net additional amount of Scheme Consideration available for Distribution to Admitted Scheme Creditors with the Initial Distribution (such net additional amount being the "CORP DISTRIBUTION SUPPLEMENT"). The Corp Distribution Supplement shall be distributed to Eligible Recipients at the times and in the manner set out in sub-clause 27(4). (3) The Elements of the Corp Distribution Supplement shall for these purposes be treated as being made up of two parts as follows: (a) the "KNOWN CLAIMS SUPPLEMENT" which shall be the Corp Distribution Supplement less the Reserve Claims Supplement; and (b) the "RESERVE CLAIMS SUPPLEMENT" which shall be the same proportion of the Corp Distribution Supplement as the Basic Reserve Claims Segment (which for this purpose shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected which results in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29) is of the Basic Scheme Consideration. 278

III. THE PLC SCHEME -------------------------------------------------------------------------------- (4) (a) The Elements of the Known Claims Supplement shall be distributed to Admitted Known Creditors at the same time as the Initial Distribution. (b) The Elements of the Reserve Claims Supplement shall be distributed to Admitted Reserve Creditors at the same time as the Initial Distribution. (5) (a) For the purposes of Distributions under the Scheme: (i) other than the Initial Distribution; and/or (ii) as regards the Initial Distribution if the provisions of sub-clause 27(2) do not come into force because one or more of the conditions in sub-clause 27(1) is not satisfied, the Supervisors may agree similar or analogous arrangements to those in sub-clause 27(2) (a "MODEL") with the supervisors of the Corp Scheme where, acting reasonably, the Supervisors consider that to do so will be in the interests of Admitted Scheme Creditors. (b) If a model is agreed pursuant to sub-clause 27(5)(a) prior to the expiry or termination of the Waiting Period, the equivalent of the Corp Distribution Supplement thereby created shall be apportioned in the same manner as provided for in sub-clause 27(3), otherwise no apportionment shall be made. (c) Any supplement arising pursuant to sub-clause 27(5)(a)(ii) which shall be apportioned in accordance with sub-clause 27(5)(b) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (d) Any supplement arising pursuant to sub-clause 27(5)(a)(i) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 27(5)(b) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (e) Any supplement arising pursuant to sub-clause 27(5)(a)(i) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. CORP RECEIPTS 28. (1) As regards: (a) the Initial Distribution if the provisions of sub-clauses 27(2)-27(4) above do not come into force for any reason; and (b) any Distributions other than the Initial Distribution, in each case, to the extent that relevant similar or analogous arrangements as referred to in clause 27(5) are not agreed in respect of the Company's entitlement to the Corp Receipts, Admitted Scheme Creditors shall be entitled to all Corp Receipts from time to time which shall be held on trust for Scheme Creditors under the Scheme. (2) If Corp Receipts arise pursuant to sub-clause 28(1) prior to the expiry or termination of the Waiting Period, those Corp Receipts shall be apportioned in the same manner as provided for in sub- clause 27(3), otherwise no apportionment shall be made. (3) Any Corp Receipts arising pursuant to sub-clause 28(1)(a) which shall be apportioned in accordance with sub-clause 28(2) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). 279

III. THE PLC SCHEME -------------------------------------------------------------------------------- (4) Any Corp Receipts arising pursuant to sub-clause 28(1)(b) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 28(2) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (5) Any supplement arising pursuant to sub-clause 28(1)(b) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. REJECTED CLAIMS 29. Where a Known Claim is Conclusively Rejected before the expiry or termination of the Waiting Period, the Distribution Entitlement to which the Known Creditor would have been entitled, had its Known Claim been Admitted rather than Conclusively Rejected shall form part of the Reserve Claims Segment. GENERAL PROVISIONS ON DISTRIBUTIONS 30. (1) No Scheme Creditor shall have any right to disturb a prior Distribution, whether on the grounds that there remains insufficient Scheme Consideration to satisfy that creditor's Distribution Entitlement (if any) or otherwise. (2) The Supervisors shall give all necessary directions and issue all necessary Distribution Notices to the Escrow Trustee (with a copy to the Distribution Agent) to enable Distributions to be made in accordance with the Scheme. The issue by the Supervisors of directions in accordance with this sub-clause 30(2) shall be a complete discharge of the Supervisors' responsibilities with respect to such Distributions. Without prejudice to the generality of the previous sentence, the Supervisors shall not be liable in any way whatsoever for any acts or omissions of the Escrow Trustee, the Distribution Agent or Bondholder Communications in respect of those directions. (3) Subject always to sub-clause 30(1), an Admitted Scheme Claim may be withdrawn or reduced as to the amount claimed by agreement between the Supervisors and the relevant Admitted Scheme Creditor. (4) Any sums of cash or rights or benefits paid, transferred or credited to the Escrow Trustee pursuant to the direction referred to in clause 34 shall be distributed together with, or, as appropriate, in place of, and at the same time as, the New Rights to which such sum of cash or other rights or benefits relate. (5) (a) Elections may be made in Claim Forms and Account Holder Letters: (i) to receive any New Shares in the form of ADRs; and/or (ii) subject to thresholds described in Recital I being met, to receive euro-denominated or US Dollar-denominated New Senior Notes (but not both); and/or (iii) to receive any New Shares: (A) in certificated form; or (B) into an account held CREST. (b) Where there are any New Shares which are not sufficient in number to equate to one ADR and which therefore cannot be transferred to the ADR Depositary in accordance with the terms of the Escrow and Distribution Agreement, the Supervisors shall direct the Escrow Trustee to procure that the Distribution Agent, acting of behalf of the Escrow Trustee shall sell those New Shares and remit the proceeds to augment the Reserve Claims Segment. 280

III. THE PLC SCHEME -------------------------------------------------------------------------------- (6) Eligible Recipients shall receive their Distributions in accordance with the provisions of the Scheme provided that no fraction of a New Share and no fraction of a New Note shall be transferred to any Eligible Recipient but : (a) if the New Shares or New Notes or any of them are Listed all fractions of such Listed New Shares or New Notes which, but for this proviso, any such Eligible Recipients would have received shall be aggregated and sold in the market and the net proceeds of sale shall comprise part of the Reserve Claims Segment; and (b) if any of the New Shares or New Notes are not Listed, all entitlements of Eligible Recipients to all fractions of such New Shares and New Notes which, but for this proviso any such Eligible Receipts would have received shall be rounded down to zero and the fractions shall comprise part of the Reserve Claims Segment. (7) (a) New Shares and New Notes will not be distributed to or to the order, or for the account or benefit, of any person where such distribution would be prohibited by any applicable law or regulation, or so prohibited except after compliance with conditions or requirements that are unduly onerous. Where any determination is required as to whether the conditions or requirements of applicable law or regulation are "unduly onerous," such determination will be made by the Company with the advice of legal counsel and having due regard for the number of Scheme Creditors and Bondholders that are or may be located in the relevant jurisdiction, the value of the securities to which such persons are or may be entitled pursuant to the Scheme, the extent to which the requirements of the laws and regulations of such jurisdiction as applied to the Scheme are uncertain, the nature and extent of the risks or penalties associated with any violation of those legal or regulatory requirements and the costs, administrative burden and timing implications of taking such action (if any) as might permit distributions of securities to be made in that jurisdiction (including pursuant to any available exemptions) in accordance with applicable legal and regulatory requirements. (b) Notwithstanding the foregoing, distribution of New Shares and New Notes will not be refused on the grounds of any legal or regulatory prohibition of general application under the laws of any Unrestricted Jurisdiction, unless there has been a Change of Law. (c) New Shares and New Notes will not be distributed to or to the order of any Scheme Creditor or Bondholder located in any Restricted Jurisdiction, except that New Shares and New Notes will be distributed to or to the order of: (i) any Scheme Creditor or Bondholder located in France if the Scheme Creditor or (as the case may be) the Bondholder and any Designated Recipient of such Bondholder is a "qualified investor" as defined in Article L.411-2 of the French Monetary and Financial Code; (ii) any Scheme Creditor or Bondholder located in Italy, if CONSOB has confirmed that such distribution does not constitute a public offering under Italian securities legislation; (iii) any Scheme Creditor or Bondholder located in Italy, if: (A) such person is a "professional investor" as defined in the Consolidated Financial Act Article 30, paragraph II and in CONSOB Regulation 11522/1998 Article 31, paragraph II; or (B) such person is not a "professional investor" as so defined but the number of such persons that are not "professional investors" does not exceed 200; and (iv) any Scheme Creditor or Bondholder located in the US states of Arizona, California, Colorado, Connecticut, Illinois, Ohio and Vermont if such persons falls within one of the relevant categories of persons set out in Schedule 4. 281

III. THE PLC SCHEME -------------------------------------------------------------------------------- Notwithstanding the foregoing, New Shares and New Notes may be distributed to or to the order of persons located in a Restricted Jurisdiction to the extent that there has been a Change of Law. (d) Notwithstanding the provisions of sub-clause 30(7)(c) above, if the confirmations required by box 3 of the Claim Form or section 5, paragraphs (D), (E) and (F) of the Account Holder Letter are given in the form requested by the Claim Form or the Account Holder Letter (as the case may be), then distribution of New Shares and New Notes to or to the order of the relevant persons will not be refused on the grounds of any legal or regulatory prohibition of general application under the laws of any Restricted Jurisdiction, unless: (i) the Company determines that such confirmations have been given inappropriately on the basis that information provided in or in connection with the transmittal of the Claim Form or Account Holder Letter indicates that such Claim Form has been submitted by, or such Account Holder Letter has been delivered on behalf of, or delivery of securities is being requested to or for the account or benefit of, a person that is located in a Restricted Jurisdiction and that could not be eligible to receive the securities under any provision described in sub-clause 30(7)(c); (ii) the Company obtains actual knowledge that such confirmations are false; or (iii) there has been a Change of Law. Notwithstanding the foregoing, New Shares and New Notes will be distributed in Italy pursuant to sub-clauses 30(7)(c)(ii)(B) and 30(7)(c)(iii)(B) (to the extent applicable) without regard to whether the required confirmations have been inappropriately or falsely given in any relevant Claim Form or Account Holder Letter. (e) To the extent that New Shares or New Notes that would otherwise be deliverable pursuant to the Scheme cannot be delivered because of a legal or regulatory prohibition described in sub- clause 30(7)(a), such New Shares or New Notes will not be delivered and instead: (i) in the case of New Shares or New Notes that are listed on a securities exchange, such New Shares or New Notes will be sold and the net proceeds of such sale delivered to the relevant person in full satisfaction of the rights of such person in respect of such New Shares or New Notes under the Scheme, all as more particularly specified in the Escrow and Distribution Agreement; and (ii) in the case of New Shares or New Notes that are not listed on a securities exchange, the relevant person will receive a sum in cash which is substantially equivalent in value to such New Shares or New Notes, such sum to be determined by agreement between the Company and the Supervisors or absent such agreement by adjudication under Part V and the Supervisors shall direct the sale of the New Shares and/or New Notes to which the relevant person would otherwise have been entitled. (8) The Supervisors shall give all appropriate directions to the Escrow Trustee (with a copy to the Distribution Agent) to give effect to this clause 30. (9) Any sale referred to in this clause 30 shall be made for the best terms reasonably available at the time of the sale and shall be undertaken on behalf of the person absolutely entitled to the relevant asset and none of the Supervisors, the Company, the Escrow Trustee, the Distribution Agent, the Registrars or any other person shall be responsible for any loss arising from the terms or timing of the sale. (10) For the avoidance of doubt, a Scheme Creditor must comply with the terms of the Scheme, including submitting a Claim Form in accordance with the provisions of clause 12, in order for its Eligible Recipient to receive any Distributions of Scheme Consideration to which that Scheme Creditor's Scheme Claim might entitle it. 282

III. THE PLC SCHEME -------------------------------------------------------------------------------- INSURED SCHEME CLAIMS 31. (1) As from the Effective Date the Company shall in respect of each and every Insured Scheme Claim but subject to sub-clauses 31(2), (3), (4), (5) and (6) hold on trust for the Scheme Creditor concerned all Insurance Recovery Rights which the Company may have in relation to that Insured Scheme Claim. (2) If Liability is established against the Company in relation to a Scheme Claim which appears to the Supervisors to be wholly or partly an Insured Scheme Claim the Supervisors shall forthwith notify the Scheme Creditor concerned: (a) the extent that the Scheme Claim appears to them to be an Insured Scheme Claim; and (b) whether the insurance contract concerned appears to permit the Scheme Creditor concerned to take an assignment of the rights referred to in sub-clause 31(3). (3) If, within 28 days of receipt of a notice given by the Supervisors pursuant to sub-clause 31(2) to the effect that the Scheme Creditor appears to have the right to an assignment conferred by this sub- clause, the Scheme Creditor in respect of such Insured Scheme Claim shall so elect by notice in writing to the Supervisors, the Supervisors shall forthwith on behalf of the Company but subject to sub-clauses 31(3)(a), (b) and (c), assign to that Scheme Creditor all Insurance Recovery Rights which the Company may have in relation to that Insured Scheme Claim, provided that: (a) if the Liability of the Insurer to the Company exceeds the amount for which the Insured Scheme Claim has been Admitted nothing in sub-clause 31(1) or in this sub-clause or in any assignment shall affect the rights of the Company against the Insurer in respect of the excess or the Company's entitlement to those rights which shall form part of the Property of the Company available for application in accordance with this Scheme; (b) if the Liability of the Insurer to the Company in respect of the Insured Scheme Claim is less than the amount for which the Insured Scheme Claim has been Admitted then the balance shall be treated as though it were a separate Known Claim or Reserve Claim as appropriate of an amount equal to such balance and if Admitted shall be entitled to rank pari passu with other Admitted Scheme Claims accordingly; and (c) the risk that the assignment will be ineffective or prejudice Insurance Recovery Rights shall vest in the Scheme Creditor. (4) If the Supervisors shall have given notice in accordance with sub-clause 31(2) in respect of a Scheme Claim then, unless all Insurance Recovery Rights in relation to that Scheme Claim shall have been assigned to the Scheme Creditor the following provisions shall apply: (a) if and to the extent that the Scheme Claim is Admitted as an Insured Scheme Claim: (i) the Supervisors shall use all reasonable endeavours to enforce for the benefit of the Scheme Creditor concerned all Insurance Recovery Rights in relation to that Insured Scheme Claim as if those Insurance Recovery Rights had been transferred to and vested in the Scheme Creditor and any monies received by the Company from an insurer in or towards settlement of those Insurance Recovery Rights shall (subject to any offset right of the Company) be held in trust for the benefit of the Scheme Creditor, provided that the Supervisors shall not be required to take any action otherwise than on the instructions of the Scheme Creditor, nor to incur any expense in relation to any Insurance Recovery Rights except to the extent that the Supervisors have been placed in funds by the Scheme Creditor to do so; and (ii) no Distributions shall be made in respect of that Insured Scheme Claim until the outcome of such enforcement is known and any monies payable in respect of the Related Insurance Recovery Rights have been received by the Company; 283

III. THE PLC SCHEME -------------------------------------------------------------------------------- (b) if the net proceeds of such enforcement shall exceed the amount at which the Insured Scheme Claim is Admitted the Supervisors shall pay to the Scheme Creditor concerned an amount equal to the amount at which the Insured Scheme Claim has been Admitted and the excess of the net proceeds shall form part of the Property of the Company available for application in accordance with this Scheme; (c) if the net proceeds of such enforcement shall be less than the amount at which the Insured Scheme Claim has been Admitted the Supervisors shall pay the net proceeds to the Scheme Creditor concerned and the balance of the amount at which the Scheme Claim has been Admitted shall be treated as through it were a separate Scheme Claim of an amount equal to the amount of such balance and shall rank pari passu with other Admitted Scheme Claims accordingly; and (d) the Supervisors may deduct from any payment and retain an amount equal to any payment received directly by the Scheme Creditor in respect of the Insured Scheme Claim under any Insurance Compensation Scheme, and that Insured Scheme Claim shall be reduced by that amount. (5) Following the service of a notice pursuant to sub-clause 31(2) the Scheme Creditor shall be entitled to receive such information from the Supervisors as is in their possession or power as the Scheme Creditor would have been entitled to receive under Section 2 of the 1930 Act in the event of a winding up order against the Company. (6) The mandatory set-off provisions in clause 5 shall apply to any payment due to any Scheme Creditor pursuant to this clause 31. 32. (1) If any questions or dispute shall arise as to the operation of clause 31, and in particular (but without limiting the generality of the foregoing) as to the part of an Insured Scheme Claim which has been Admitted which is to be treated as a separate Admitted Scheme Claim the question or dispute shall be referred to an individual agreed between the Supervisors and the relevant Scheme Creditor to adjudicate on such question or dispute (being an independent third party considered by the Supervisors and the relevant Scheme Creditor to be a fit and proper person duly qualified to adjudicate on the points at issue) or in the absence of any such agreement between the relevant Scheme Creditor and the Supervisors, a person nominated by The President of the Law Society of England and Wales. (2) The Supervisors shall provide the person to whom the question or dispute is referred (the "INDEPENDENT ADJUDICATOR") with copies of the correspondence between the parties relating to the question or dispute and any other relevant documentation. The Independent Adjudicator shall be entitled to call for copies of any further documentation he considers necessary to assist him to reach a decision and the Supervisors and the Scheme Creditor concerned shall co-operate in providing such information. The Independent Adjudicator shall notify the Supervisors and the relevant Scheme Creditor of his decision by notice in writing sent by Post as soon as may be practicable. (3) Subject to any mandatory applicable law, the determination of the Independent Adjudicator as to any such question or dispute shall be final and binding on the Company and the Supervisors and the Scheme Creditor concerned and, for the avoidance of doubt, there shall be no right of appeal therefrom, and no right to make any claim against the Independent Adjudicator in respect thereof. For the avoidance of doubt, this exclusion of any right of appeal shall operate only to the extent permitted by law. 284

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART IV ESCROW AND DISTRIBUTION ARRANGEMENTS ESCROW AND DISTRIBUTION AGREEMENT 33. On the Effective Date, those provisions of the Escrow and Distribution Agreement which have not already come into force shall come into force in accordance with its terms. In particular, but without limitation, the Company, forthwith upon the Effective Date, shall procure that the Basic Scheme Consideration shall be paid or transferred to the Escrow Trustee to be dealt with in accordance with the Escrow and Distribution Agreement. The Company shall procure that any Corp Receipts shall (as soon as practicable after receipt by the Company) be paid or transferred to the Escrow Trustee to be dealt with in accordance with the Escrow and Distribution Agreement. SCHEME CONSIDERATION WHEN HELD IN ESCROW BY THE ESCROW TRUSTEE 34. plc shall direct that all of the Scheme Consideration transferred to the Escrow Trustee shall be held by the Distribution Agent as custodian for the Escrow Trustee. The Escrow Trustee shall hold that Scheme Consideration on bare trust absolutely for the Scheme Creditors on the basis set out in the Escrow and Distribution Agreement. So as to bind the Scheme Creditors and any persons deriving title from them, the Scheme Consideration shall be applied by the Escrow Trustee on behalf of the Scheme Creditors absolutely entitled to it, in accordance with the Escrow and Distribution Agreement and the provisions of the Scheme. Subject to the provisions of the Escrow and Distribution Agreement the Escrow Trustee shall at no time whatsoever, either present or future, have any beneficial interest in the Scheme Consideration. 35. Whilst any New Shares, New Notes or other similar instruments (if any) or cash are held by or on behalf of, the Escrow Trustee: (1) dividends paid on (or any other rights or benefits added or attached to) such New Shares or similar instruments; and/or (2) interest accrued on any such cash or interest paid on any such New Notes (or similar instruments); and/or (3) any cash arising from the prepayment by Corp of any such New Senior Notes or New Junior Notes in accordance with their terms and any interest accruing thereon, shall be paid, transferred or credited to the Escrow Trustee to hold on the terms of the Escrow and Distribution Agreement. 36. The Escrow Trustee shall not exercise any voting rights attaching to any New Notes or New Shares held in escrow. 37. (1) The Escrow Trustee's liabilities as trustee shall be solely those arising out of its trusteeship and other obligations set out in the Escrow and Distribution Agreement. (2) The Distribution Agent's liabilities as custodian for the Escrow Trustee and as distribution agent shall be solely those arising out of its custodianship and other obligations set out in the Escrow and Distribution Agreement. 285

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART V INDEPENDENT ADJUDICATION 38. If any question or issue in relation to the existence or quantum of a Scheme Claim shall be referred for adjudication as a result of an election made pursuant to clause 17 or the question of what sum an Eligible Recipient shall be entitled to shall be referred for adjudication pursuant to sub-clause 30(7)(e)(ii), the question or issue shall be referred for adjudication to an individual agreed between the Supervisors and the relevant Scheme Creditors (the "COUNTERPARTY"), such individual to be an independent third party considered by the Supervisors and the Counterparty to be a fit and proper person duly qualified to adjudicate on the question or issue, or in the absence of any such agreement between the Supervisors and the Counterparty within 10 Business Days of the election, to an individual nominated by The President of the Law Society of England and Wales. 39. The individual to whom the question or issue is referred (the "ADJUDICATOR") shall be entitled to prescribe such reasonable provisions and procedures as, in his absolute discretion, he may consider appropriate for the purposes of assisting him in reaching his decision, and shall be entitled for such purpose to call for such evidence in relation to the question or issue referred to him as he may require, provided that the Counterparty and the Company shall always be afforded a reasonable opportunity to make oral submissions to the Adjudicator. In any one adjudication, such oral submissions shall not in aggregate occupy more than one working day save with the approval, in his absolute discretion, of the Adjudicator. 40. With regard to any adjudication before him, the Adjudicator may make such directions in respect of payment of his remuneration and in respect of the costs, charges and expenses incurred by him, the Supervisors, the Company or the Counterparty as he shall think just. In particular, but without limitation, one party may be directed to pay remuneration and costs, charges and expenses of another party if, in the opinion of the Adjudicator, any such party has made a claim, relied on a defence or otherwise howsoever conducted himself in relation to the adjudication in a manner which is frivolous, vexatious or had no reasonable prospect of success. 41. If the Adjudicator shall direct that any such remuneration, costs, charges and expenses be paid by the Supervisors or by the Company, the same shall forthwith be paid in full by the Company. 42. If the Adjudicator shall direct that any such remuneration, costs, charges and expenses be paid by the Counterparty, the same shall forthwith be paid in full by the Counterparty and, if not so paid then, for the purposes of determining whether such Counterparty is entitled to participate in any distribution under the Scheme, he shall be treated as having received on account an advance distribution under the Scheme equal to the amount which he has been directed to pay. 43. Subject to any directions which may be given by the Adjudicator in accordance with clause 40, the Company shall pay all costs, charges and expenses incurred by the Adjudicator in the course of exercising and performing his powers, duties and functions under the Scheme and shall pay such remuneration to the Adjudicator for the exercise and performance of his powers, duties and functions as may be agreed between the Adjudicator and the Supervisors and approved by the Creditors' Committee. 44. The Adjudicator shall notify the Supervisors and the relevant Counterparty of his decision by notice in writing by Post as soon as practicable. 45. Subject to any mandatory applicable law, the determination of the Adjudicator of any question or issue shall be final and binding on the Company, the Supervisors and the Counterparty and, for the avoidance of doubt, there shall be no right of appeal therefrom, and no right to make any claim against the Adjudicator in respect thereof. For the avoidance of doubt, this exclusion of any right of appeal shall operate only to the extent permitted by law. 46. If at the expiration of 6 months in the case of a question or issue referred for adjudication as a result of an election made pursuant to clause 17 or of 3 months in the case of a question or issue referred for adjudication pursuant to sub-clause 30(7)(e)(ii) no decision on such question or issue has been reached by an Adjudicator, then nothing in this Scheme shall preclude the Counterparty from taking any appropriate action in the Court for the purposes only of securing a determination of the question or issue concerned. 286

The Supervisors shall have the powers, duties and functions conferred upon them by the Scheme and any other documents entered into pursuant to the Scheme. 48.

III. THE PLC SCHEME -------------------------------------------------------------------------------- 54. The Supervisors shall, with effect from the Effective Date, ensure that there is in force in relation to the Company such bond as would have had to be in force if the Company had been wound up in England on the Effective Date and they had been appointed as liquidators of the Company. 55. Without prejudice to the generality of clause 53, in carrying out their functions and powers under the Scheme the Supervisors shall be entitled: (1) to admit or refuse to admit Scheme Claims Submitted by Scheme Creditors (including to ensure the Company properly conducts its defence of any Prohibited Proceedings and/or any Allowed Proceedings) and direct: (a) Distributions; and (b) realisations of Scheme Consideration to generate cash for Distributions by the Distribution Agent in accordance with the Scheme and the Escrow and Distribution Agreement; (2) to have access at all reasonable times to all relevant employees, books, papers and other documents of the Company and to receive all such information from the Company as they may reasonably require in relation to their duties as Supervisors and to receive the reasonable co-operation of the Company in connection with the conduct of any Prohibited Proceedings, any Allowed Proceedings or defending any Proceedings against the Supervisors in respect of carrying out their functions and exercising their powers under the Scheme; (3) to delegate to any Employee all or any of the functions, powers, rights, authorities and discretions conferred upon the Supervisors under the Scheme and from time to time to revoke any such delegation, provided that the Supervisors shall be responsible for any act or omission of any such employee or delegate to the same extent as if they had expressly authorised it; (4) to be remunerated for the carrying out of such functions and powers (in the case of the initial Supervisors, Philip Wedgwood Wallace and Richard Heis, such remuneration to be calculated by reference to the Supervisors' Engagement Letter) and to be reimbursed for all expenses properly incurred by them in connection with this clause including any adverse costs ordered to be paid by the Supervisors as a result of any Proceeding in connection with the Scheme; (5) to defend any proceedings against them in respect of carrying out their functions and exercising their powers under the Scheme; (6) to apply to the Court for directions in relation to any particular matter arising in the course of the Scheme; (7) to liaise with the Creditors' Committee and to attend Creditors' Committee meetings; (8) to convene a meeting of Scheme Creditors in accordance with Part VIII, if appropriate; (9) to exercise the powers listed in schedule 1 to the Insolvency Act 1986; and (10) to exercise such powers as are necessary or desirable to enable them to fulfil their functions under the Scheme and to do all other things incidental to the exercise of the functions and powers referred to in this and clause 53. 56. Save as expressly set out in this Scheme, the Supervisors shall be entitled to employ and remunerate accountants, actuaries, lawyers and other professional advisers or agents in connection with the conduct of their functions and powers under the Scheme. 57. Any function of or power conferred on the Company or its officers, whether by statute or by its memorandum or articles of association, which could be exercised in such a way as to interfere with the exercise by the Supervisors of their functions and powers in relation to the Company or the Scheme shall not be so exercised except with the consent of the Supervisors, which may be given either generally or in relation to particular cases. Any such consent given by the Supervisors may be withdrawn. 288

(2) When the Company, acting through the Supervisors, gives directions under: (a) sub-clauses 4(c) and (d); (b) sub-clauses 5(3), 5(5), 5(8) and (9) (c) sub-clauses 6(1), 6(2), (3), 6(4) and 6(8); (d) sub-clause 7(10); (e) sub-clause 8(10); (f) sub-clause 9(22); (g) sub-clause 11(2); (h) clause 12; or (i) sub-clause 13(1), of the Escrow and Distribution Agreement or sub-clause 111(3), the Company gives those directions for and on behalf of the Scheme Creditors who are absolutely entitled to the assets affected by those directions under clause 5(7) of the Escrow and Distribution Agreement and so as to procure that their obligations under clause 34 fulfilled. 60. (1) To the extent permitted by law, no Scheme Creditor shall be entitled to challenge the validity of any act done or omitted to be done in good faith and with due care by the Supervisors in accordance with and to implement the provisions of the Scheme or the exercise by the Supervisors in good faith and with due care of any power conferred upon them for the purposes of the Scheme if exercised in accordance with and to implement the provisions of the Scheme and the Supervisors shall not be liable for any loss unless such loss is attributable to their own negligence, default, breach of duty, breach of trust, fraud or dishonesty (or to the negligence, default, breach of duty, breach of trust, fraud or dishonesty of any Employee). 289

Subject to clause 77 the quorum at any meeting of the Creditors' Committee shall be at least two-thirds of the Committee Members, provided that if a quorum is not present within 30 minutes from the time appointed for a meeting, or if during a meeting such a quorum ceases to be present, the meeting shall stand adjourned to such time and place as may be determined by the majority of the Committee Members present and the Committee Members present at any such meeting reconvened following an adjournment shall constitute a quorum. Each Committee Member shall have one vote and, except as otherwise provided in the Scheme, matters arising at a meeting shall be decided by a majority of votes cast at the meeting. 292

III. THE PLC SCHEME -------------------------------------------------------------------------------- 73. The Creditors' Committee shall meet at least once every 12 months for the purpose of receiving a report from the Supervisors on the progress of the Scheme. The Creditors' Committee shall hold such further meetings as it considers desirable for the purpose of performing its functions under the Scheme. A meeting of the Creditors' Committee shall be called as soon as reasonably practicable if so requested by at least two Committee Members or if the Supervisors otherwise consider it appropriate. Except with the consent of all Committee Members, no meeting of the Creditors' Committee may be called on less than ten Business Days' notice and, except with the consent of all Committee Members, no business may be transacted at any such meeting other than that set out in the notice of that meeting. 74.

Each Committee Member (including any Nominated Representative or Alternate) and the Supervisors (or their representatives) shall be entitled to attend and receive notice of all meetings of the Creditors' Committee. The Supervisors shall be entitled to attend and speak, but not to vote, at all meetings of the Creditors' Committee.

A Committee Member (including any Nominated Representative or Alternate) and the Supervisors may participate in a meeting of the Creditors' Committee through the medium of conference telephone or similar form of communication equipment if all persons participating in the meeting are able to hear and speak to each other throughout the meeting. A person participating in this way is deemed to be present in person at the meeting and, in the case of a Committee Member (including any Nominated Representative or Alternate), is counted in a quorum and entitled to vote. All business transacted in this way by the Creditors' Committee is deemed to be validly and effectively transacted at a meeting of the Creditors' Committee although fewer than two-thirds of the Committee Members are physically present at the same place. If, at any time during a Committee Meeting any person participating in the meeting ceases to be able to hear and speak to all other Committee Members, Nominated Representatives or Alternates, whether participating in the Committee Meetings through the medium of conference telephone or similar form of communication equipment or in person, the meeting shall be adjourned and reconvened when full communication between those Committee Members attending the meeting is restored. 78. Other than in relation to such a resolution as is referred to in clause 82, a resolution in writing signed by all Committee Members for the time being shall be valid and effective as if passed at a meeting of the Creditors' Committee duly convened and held. POWERS 79. (1) The Creditors' Committee shall have the powers specifically set out in the Scheme. (2) If the Supervisors determine that the costs of making any further Distribution of Scheme Consideration would exceed the value of the Scheme Consideration remaining to be distributed, the Creditors' Committee may direct the Supervisors to procure the sale of such Scheme Consideration and distribute the proceeds of such sale provided that the costs of making such Distribution do not exceed the proceeds of sale to be distributed. 80. Before each meeting of Scheme Creditors convened pursuant to clause 93 the Supervisors shall submit to the Creditors' Committee a report on the operation of the Scheme during the period since the last such report was prepared (or, in the case of the first such meeting, since the Effective Date) and shall (or shall appoint a representative to) attend at any meeting of the Creditors' Committee at which that report is considered for the purpose of giving such explanations and information as the Creditors' Committee may 293

III. THE PLC SCHEME -------------------------------------------------------------------------------- require. A copy of that report, incorporating such amendments (if any) as may be agreed by the Supervisors and the Creditors' Committee, shall be made available to Scheme Creditors in accordance with clauses 95 and 96. 81. The Creditors' Committee may from time to time resolve to seek information from the Supervisors concerning the operation of the Scheme, and may depute any one Committee Member to apply in writing to request and receive from the Supervisors any or all such information. The Supervisors shall promptly give to the Creditors' Committee all such information reasonably requested concerning the operation of the Scheme as the Creditors' Committee shall from time to time resolve to seek and in respect of which a written request shall have been received by the Supervisors. Each Committee Member shall be entitled at any time to raise questions or to request a meeting with the Supervisors in connection with the performance of his responsibilities as a Committee Member and, subject to their duties under the Scheme the Supervisors shall use reasonable endeavours to respond to such questions or to comply with any such request for a meeting. Notwithstanding the preceding provisions of this clause the Supervisors shall not be obliged to disclose: (1) any confidential information of the Company to a Committee Member if the information relates, or the Supervisors reasonably believe that the information relates, to any matter where such Committee Member has an interest in conflict with the Company (other than a general conflict arising as a result of the status of the Committee Members (or their appointors) as Scheme Creditors); or (2) any information which could cause the Company to breach insider dealing rules, the Financial Services and Markets Act 2000 or the Listing Rules of the UKLA. 82. The Creditors' Committee shall be entitled: (1) by a resolution passed by at least three-fourths of all of the Committee Members present and voting at any time to call upon a Supervisor to resign, provided that each such Supervisor and each Committee Member have been given at least 20 Business Days' notice of the proposed resolution and of the reasons why the resolution is to be put to the Creditors' Committee and have been given a reasonable opportunity to make representations at the meeting at which the resolution is proposed. If the Supervisor declines to resign within 5 Business Days of a resolution of the Creditors' Committee calling for his resignation a resolution requiring his removal shall be put before the next meeting of the Scheme Creditors and, if passed, the Supervisor shall vacate the office of Supervisor; (2) upon removal of a Supervisor or if a Supervisor ceases to hold office for any other reason, to appoint any person qualified to act under clause 48 to be a Supervisor in their place (and a resolution requiring ratification of such appointment shall be put before the next meeting of Scheme Creditors pending which the appointee shall have full power to act as a Supervisor) save that if a resolution is passed at a meeting of Scheme Creditors requiring the removal of any of the Supervisors pursuant to sub-clause 82(1) such appointment may be made by the Scheme Creditors at such meeting. 83. The Creditors' Committee shall be entitled to engage legal and financial advisers from time to time as reasonable in order to assist them in carrying out their functions as the Creditors' Committee. At any particular time, the Creditors' Committee may only engage one legal and one financial adviser. Reasonable costs of such advisers are Scheme Expenses. 84. The Creditors' Committee and the Company shall use reasonable endeavours to ensure that there are two duly qualified Supervisors in office at all times. DUTIES 85. Each Committee Member, each Nominated Representative, and each Alternate shall, in performing their functions as such in relation to the Scheme, act bona fide in what he or she reasonably considers to be the interests of the Scheme Creditors as a whole. For the avoidance of doubt (but without prejudice to its 294

III. THE PLC SCHEME -------------------------------------------------------------------------------- specific powers as set out by the Scheme) it shall not be the duty of the Creditors' Committee to monitor the carrying out of the Scheme or the activities of the Supervisors. 86. It shall be the duty of each Committee Member who is in any way, whether directly or indirectly, interested in a contract or arrangement or proposed contract or arrangement with the Company (other than any which arises as a result of the provisions of the Scheme) to declare (or procure that its Nominated Representative or Alternate shall declare) the nature of his or its interest at a meeting of the Creditors' Committee. For this purpose a general notice given to the Creditors' Committee to the effect that a Committee Member is an associate (within the meaning of section 435 of the Insolvency Act 1986) of a specified company or firm and is to be regarded as interested in any contract with that company or firm shall be deemed a sufficient declaration of interest in relation to any such contract or arrangement. Such a Committee Member shall not be counted in the quorum, shall not be entitled to vote in relation to any matter relating specifically to any such contract, shall retire from the meeting for so long as the matter is discussed and voted upon and shall not receive any information, nor be entitled to inspect any part of the minutes of a meeting of the Creditors' Committee, relating thereto. 87. Each Nominated Representative or Alternate shall be entitled to report to the Committee Member appointing him on the proceedings of the Creditors' Committee and, so far as necessary for that purpose, to disclose confidential information of the Company to those officers, employees and professional advisers of that member or appointor who need to know it in connection with (where a Nominated Representative or Alternate is disclosing information) the performance of his or its responsibilities as a Committee Member, provided that such information does not to his or its knowledge (after due enquiry) relate to any matter where any such appointor has an interest in conflict with the Company (other than a general conflict arising as the result of the status of Committee Members or the appointors of a Nominated Representative or Alternate as Scheme Creditors). Each Committee Member shall, and shall procure that its Nominated Representative or Alternate and its officers, employees and professional advisers shall preserve the confidentiality of such information and shall use such information only for the purposes of their performing their responsibilities and functions (or their Nominated Representative's or Alternate's responsibilities and functions) in relation to the Creditors' Committee. RESPONSIBILITY 88. No Scheme Creditor, Supervisor or the Company shall be entitled to challenge the validity of any act done or omitted to be done in good faith by any Committee Member (or Nominated Representative or Alternate) in accordance with and to implement the provisions of the Scheme or the exercise by any such Committee Member (or Nominated Representative or Alternate) in good faith of any power conferred upon it or him by or for the purposes of the Scheme if exercised in accordance with and to implement the provisions of the Scheme and no such Committee Member (or Nominated Representative or Alternate) shall be liable for any loss or damage unless such loss or damage is attributable to its or his own wilful default, fraud, dishonesty or wilful breach of duty. VALIDATION OF ACTS 89. All acts done by the Creditors' Committee or any member of the Creditors' Committee or any person acting as a Committee Member or as a Nominated Representative or Alternate shall, notwithstanding that it is afterwards discovered that there was some defect in the appointment of a Committee Member or person acting as aforesaid, or that any of them were disqualified, be valid as if every such person had been duly appointed and qualified. EXPENSES 90. Each member of the Creditors' Committee, each Nominated Representative and each Alternate shall be entitled to be reimbursed by the Supervisors from the Expenses Fund upon written demand to the Supervisors for their reasonable out of pocket expenses incurred in attending meetings of the Creditors' Committee, provided that such meetings are held in London or in such other place as the Supervisors may from time to time agree. Where a Committee Member, its Nominated Representative or any Alternate 295

III. THE PLC SCHEME -------------------------------------------------------------------------------- appointed by the Committee Member or its Nominated Representative must travel to attend a Creditors' Committee meeting in London (or such other place as the Supervisors have agreed), that Committee Member or Nominated Representative shall (and that Alternate shall procure that the Committee Member or Nominated Representative shall) use all reasonable endeavours to appoint as its Nominated Representative or Alternate (as the case may be) for that meeting an individual who is based in locality of the venue of that Creditors' Committee meeting. The Supervisors, acting reasonably, may permit the reasonable out of pocket expenses incurred by a member of the Creditors' Committee, Nominated Representative or Alternative to include the costs of an air fare required to allow such Committee Member, Nominated Representative or Alternate to attend the Creditors' Committee meeting. Where the cost of an air fare is so permitted, it shall be the cost of an economy class fare only. NO CREDITORS' COMMITTEE 91. (1) If at any time there are less than three members of the Creditors' Committee or such lesser number as permitted by sub-clause 62(2), the Creditors' Committee may continue to exercise all its functions under the Scheme (other than those provided for in clause 82 and sub-clause 93(2)) for a period of 28 days, during which time the remaining Committee Members shall endeavour to fill the vacancies on the Creditors' Committee. (2) If the Committee Members fail to fill vacancies on the Creditors' Committee within such period of 28 days, the Supervisors shall use all reasonable endeavours to appoint, within a further 14 days, such additional Scheme Creditors ("INTERIM APPOINTEES") to the Creditors' Committee as are required to fill such vacancies. Interim Appointees may appoint a Nominated Representative or Alternate pursuant to sub-clauses 62(4) and 62(5). (3) In appointing any Interim Appointees pursuant to sub-clause 91(2), the Supervisors shall endeavour to ensure that the composition of the Creditors' Committee including such Interim Appointees is such as to represent a proper balance of the interests of the Scheme Creditors as a whole. (4) In the event of vacancies on the Creditors' Committee being filled, whether by appointees of the Creditors' Committee pursuant to sub-clause 91(1) or by Interim Appointees appointed by the Supervisors pursuant to sub-clause 91(2), the full powers and functions of the Creditors' Committee under the Scheme shall be restored, provided that no Interim Appointee shall be entitled to vote in relation to any resolution to appoint an additional Committee Member. (5) Any Interim Appointee shall be liable to be removed as a Committee Member at any time without notice if the Creditors' Committee (excluding any Interim Appointees) appoints a Scheme Creditor to fill the vacancy which had been filled by such Interim Appointee. (6) If at any time after the operation of this clause there are no members of the Creditors' Committee, the Supervisors shall be entitled to continue to carry out their functions and exercise the necessary powers pursuant to the terms of the Scheme, save that the Supervisors shall not be required to provide reports to the Creditors' Committee or obtain the approval of the Creditors' Committee for the purposes of clause 117. 92. If, following the procedure set out in clause 91, there are less than three Committee Members (including Interim Appointees) or such lesser number as permitted by sub-clause 62(2) then, for so long as that is the case, the Creditors' Committee shall not exercise any functions or have any powers under the Scheme and the following provisions shall apply: (1) the Supervisors shall use reasonable endeavours to find additional Committee Members to enable it to function; (2) any Supervisor may resign under clause 49 provided that a replacement Supervisor is appointed in his place at a meeting of the Scheme Creditors pursuant to a resolution proposed by the Supervisors; 296

III. THE PLC SCHEME -------------------------------------------------------------------------------- (3) any Supervisor may be removed, provided that a replacement Supervisor is appointed in his place at a meeting of the Scheme Creditors pursuant to a resolution proposed by any ten Scheme Creditors who have Scheme Claims of an aggregate value in excess of 15 per cent. of all Scheme Claims or any 30 Scheme Creditors; and (4) the requirements for obtaining the consent, approval of and for consulting with or notifying the Creditors' Committee and for submitting a report to the Creditors' Committee shall be suspended. 297

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART VIII MEETINGS OF SCHEME CREDITORS CONVENING OF MEETINGS 93. Meetings of Scheme Creditors are to be convened as follows: (1) The Supervisors shall convene a meeting of the Scheme Creditors at least once every 12 months unless the Supervisors and the Creditors' Committee agree otherwise. (2) The Creditors' Committee may at any time require the Company to convene a meeting of the Scheme Creditors to consider a resolution: (a) for the removal of a Supervisor pursuant to sub-clause 82(1); (b) for the appointment of a Supervisor pursuant to sub-clause 82(2); or (c) for such other purpose as it thinks fit. (3) The Supervisors may at any time convene a meeting of the Scheme Creditors for such purpose as they think fit. (4) Any five or more Scheme Creditors who have Scheme Claims of an aggregate value in excess of 15 per cent. of all Admitted and Unadmitted Scheme Claims or any 20 Scheme Creditors may by notice in writing signed by them or on their behalf and deposited at the registered office of the Company require the Supervisors to convene a meeting of Scheme Creditors for such purpose as they think fit. The relevant Scheme Creditors must specify the purpose for which the meeting is required and it shall be the duty of the Supervisors forthwith to summon a meeting of Scheme Creditors for that purpose and to give such notice of the meeting as is necessary to enable such purpose to be carried out effectively in accordance with the provisions of the Scheme. 94. The Company may appoint a representative or representatives to attend any meeting of Scheme Creditors for the purposes of observing the meeting only. 95. There shall be laid before each meeting of Scheme Creditors convened pursuant to clause 93 the report referred to in clause 80 unless the Supervisors and the Creditors' Committee agree that any such meeting should not be held, in which case a copy of the report shall be sent by the Supervisors to the Scheme Creditors upon request from the Scheme Creditors to the Supervisors. 96. At least 20 Business Days' notice shall be given of a meeting of Scheme Creditors. Such notice shall be exclusive of the day on which it is served or deemed to be served and of the day for which it is given, and shall (in the case of a meeting convened pursuant to clause 93) specify the place and time of the meeting and the place from which a copy of the report referred to in clause 80 can be obtained by Scheme Creditors upon request from the Scheme Creditors to the Supervisors prior to the meeting. 97. Any costs incurred in the production and distribution of the report referred to in clause 80 are Scheme Expenses. 98. Notice of a meeting of Scheme Creditors shall be given by the Supervisors or the Creditors' Committee, as the case may be, convening the meeting: (1) to each Admitted Scheme Creditor, and to any other Scheme Creditor who has applied in writing to the Company to receive notice of such meeting, by sending a notice by Post to such Scheme Creditor at his last known address; (2) to all other Scheme Creditors by placing advertisements containing the requisite information in such newspaper or newspapers as the Supervisors shall consider appropriate; (3) where called by the Creditors' Committee, to the Supervisors; (4) where called by the Supervisors, to each Committee Member; and (5) the Company. 298

III. THE PLC SCHEME -------------------------------------------------------------------------------- 99. The accidental omission to give notice of a meeting of Scheme Creditors to, or the non-receipt of a notice of such a meeting by, any person entitled to receive notice shall not invalidate the proceedings at that meeting. RESOLUTIONS 100. If a meeting of Scheme Creditors is convened at a time when a resolution is to be put to the next meeting of Scheme Creditors pursuant to clause 65, the business of the meeting shall include the resolution concerned, and in the case of a resolution to remove a Supervisor pursuant to sub-clause 82(1) which, if passed, would result in there being less than two Supervisors in office, shall also include a resolution that a named person qualified to act under clause 48 and willing to be appointed, be appointed as a Supervisor in their place. 101. No meeting shall be validly convened unless the notice of the meeting sets out the text of each resolution or an adequate summary thereof, which is to be proposed at the meeting (or if no resolution is to be proposed at the meeting, the nature of the business to be discussed thereat) and (in the case of a notice which is sent by Post) is accompanied by a letter explaining (in relation to each such resolution) why the meeting is being convened. VOTING 102. A resolution put to a meeting of Scheme Creditors shall be effective only if it is approved by a majority in number representing three-fourths in value of the Scheme Claims of Scheme Creditors which are present and voting either in person or by proxy at the meeting. 103. Every Scheme Creditor entitled to vote shall have the right to appoint any person as his proxy to attend and vote instead of him. The instrument appointing a proxy may be in any form which the Supervisors may approve and must be lodged at the place specified in the notice of the meeting for the lodging of proxies not less than 48 hours before the meeting (or adjourned meeting) at which it is to be used. 104. No business shall be transacted at any meeting of Scheme Creditors unless a quorum is present when the meeting proceeds to business. 20 Scheme Creditors present in person or by proxy and having the right to vote at the meeting shall be a quorum, unless the Supervisors and the Creditors' Committee agree a smaller number. All resolutions put to the vote of any meeting shall be decided on a poll (rather than on a show of hands). 105. One of the Supervisors shall preside (or shall nominate a representative to preside) at each meeting of the Scheme Creditors (other than at a meeting at which a resolution to remove a Supervisor is proposed, when the chairman of the Company shall preside), but if the Supervisor (or his nominated representative) or, if relevant, the chairman of the Company is not present within 30 minutes after the time appointed for opening the meeting or is unwilling to preside, the Scheme Creditors present in person or by proxy shall choose some member of the Creditors' Committee or, if no such member is present or if all such members present decline to preside, one of themselves, to be chairman of the meeting. If no person is willing to preside as chairman of the meeting, the meeting shall be adjourned for seven days, and, if no person is willing to preside as chairman of such meeting reconvened following an adjournment, the meeting shall be dissolved. VALUATION OF SCHEME CLAIMS FOR THE PURPOSES OF MEETINGS 106. For the purposes of valuing any Scheme Claim which a Scheme Creditor has for either of the purposes referred to in sub-clause 93(4) and clause 102 the value of the Scheme Claim shall, in the case of a Scheme Claim which has been Admitted, be the amount of the Admitted Scheme Claim so established (or relevant part thereof) and, in the case of any other Scheme Claim, be such amount as may, for the purposes of such meeting only, be estimated as the value of such Scheme Claim (or relevant part thereof) by the chairman of the meeting. The operation of clause 7 shall not have the effect of extinguishing a Scheme Claim for the purposes of this Part VIII. 299

III. THE PLC SCHEME -------------------------------------------------------------------------------- 107. In the event that a Scheme Creditor disputes the value which has been put on its Scheme Claim, pursuant to clause 106 or otherwise, the dispute shall be referred to the President at that time of the Institute of Chartered Accountants in England and Wales (or, if one of the Supervisors or any of their partners at such time occupies such office, the President of the Law Society of England and Wales) or such other individual qualified to act as an insolvency practitioner within the meaning of section 390 of the Insolvency Act 1986 as such President may nominate. Such nominee shall consult with such relevant experts as he thinks appropriate and shall act as an expert not an arbitrator and his decision (including as to who should bear the costs of such referral) shall be final (but only as regards the convening of the meeting or the vote on that occasion). 108. For the purposes of ascertaining whether or not the requisite percentage for the convening of any meeting of Scheme Creditors or the requisite majority at any meeting of Scheme Creditors has been obtained, the amount of each Scheme Claim (or relevant part thereof) which is denominated in a currency other than sterling shall be converted into sterling at the Scheme Rate. 300

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART IX TERMINATION 109. This Scheme shall be unaffected by any future liquidation of the Company and shall in those circumstances continue according to its terms. 110. (1) As soon as reasonably practicable after the making of the Final Distribution or the Supervisors' determination that any further distribution of Scheme Consideration (or the distribution of the proceeds of sale of such Scheme Consideration) would be uneconomic, the Supervisors shall serve the Termination Notice on the Company, the members of the Creditors' Committee and the Scheme of Creditors. For the avoidance of doubt, the Supervisors shall not direct the Final Distribution (or determine that any further distribution of Scheme Consideration, or the proceeds of sale of such Scheme Consideration would be uneconomic) until all Unadmitted Claims have become Admitted or Conclusively Rejected. (2) If the Supervisors, acting reasonably, determine that any further distribution of Scheme Consideration (or the distribution of the proceeds of sale of such Scheme Consideration) would be uneconomic, the remaining Scheme Consideration shall in each case be sold and the net proceeds of sale shall (on behalf of the Scheme Creditors for whose absolute benefit that Scheme Consideration is held under the Escrow and Distribution Agreement) be paid to the Company for its own use and benefit absolutely. (3) For the purposes of clause 110 a distribution shall be uneconomic if the costs of making the distribution would exceed the value of the Scheme Consideration (or proceeds of sale of such Scheme Consideration) to be distributed. 111. With effect from the issue of the Termination Notice: (1) the Scheme Creditors, the Creditors' Committee, the Company, the Supervisors, the Eurobond Trustee, the Yankee Bond Trustee, the Escrow Trustee, the Distribution Agent, the Registrars and Bondholder Communications shall have no further rights and obligations under this Scheme except any rights arising as a result of sub-clause 7(2); and (2) the Supervisors (and any former Supervisors) and the members of the Creditors' Committee (and any former members) shall be discharged from liability for their respective acts, omissions and conduct pursuant to or under the Scheme other than liability arising: (a) in the case of the Supervisors (and any former Supervisors), as a result of their own negligence, default, breach of duty, breach of trust, fraud or dishonesty (or as a result of the negligence, default, breach of duty, breach of trust, fraud or dishonesty of any Employee); and (b) in the case of the members of the Creditors' Committee (and any former members), from loss or damage attributable to its or his own wilful default, fraud, dishonesty or wilful breach of duty. (3) Where a Termination Notice is served pursuant to sub-clause 117(3), so as to bind Scheme Creditors and any person deriving title from them the Supervisors shall direct the Escrow Trustee to transfer, or procure the transfer of, to the Company (or as the Company shall direct) all Scheme Consideration not previously the subject of a Distribution this being done by the Escrow Trustee on behalf of the Scheme Creditors absolutely entitled to such remaining Scheme Consideration. 112. Prior to the issue of the Termination Notice, the Supervisors shall take steps to ensure that any sum remaining in the Unclaimed Dividends Fund remains available for distribution to relevant shareholders or former shareholders of the Company notwithstanding the termination of the Scheme. 301

III. THE PLC SCHEME -------------------------------------------------------------------------------- PART X GENERAL SCHEME PROVISIONS EFFECTIVE DATE AND NOTIFICATION 113. The Company shall give notification of the Scheme having become effective by placing advertisements in The Times and the world-wide editions of the Wall Street Journal, the Financial Times and the International Herald Tribune as soon as reasonably practicable following the occurrence of the Effective Time. COSTS 114. There shall be paid in full by the Company all costs, charges, expenses and disbursements reasonably incurred by the Company in connection with the negotiation, preparation and implementation of the Scheme as and when they arise, including the costs of holding the meeting of creditors of the Company convened pursuant to the order of the Court to consider the Scheme and the costs of obtaining the sanction of the Court and the costs of placing the notices required by the Scheme. 115. The Company shall pay the costs, charges, expenses and disbursements reasonably incurred by the Escrow Trustee, the Distribution Agent, the Eurobond Trustee, the Yankee Bond Trustee, the security trustee in respect of the New Notes, the Co-ordination Committee and the Informal Committee of Bondholders and the costs of their respective legal and financial advisors in connection with the negotiation, preparation and implementation of the Scheme, including for the avoidance of doubt, the costs of legal and financial advisers to the Creditors' Committee permitted in accordance with clause 83. 116. The Company shall be maintained in existence until, after the Termination Date, it is dissolved, struck off the register of companies or put into liquidation and the costs of maintaining it in existence, including the costs incurred in ensuring that it complies with its statutory obligations ("ONGOING PLC COSTS"), shall be paid out of the Expenses Fund. 117. (1) For the avoidance of doubt, save as expressly provided in the Scheme, any costs, charges, expenses, remuneration and disbursements which are expressed to be payable by the Company in accordance with the terms of the Scheme (including those provided for in Parts VI, VII and VIII and in this Part X of the Scheme) shall be paid out of the Expenses Fund. (2) If at any time in the reasonable opinion of the Supervisors the Expenses Fund is insufficient to pay in full any sum which is expressed to be payable by the Company or from the Expenses Fund in accordance with the provisions of this Scheme then subject to the proviso below, the Supervisors may raise such sum from the Scheme Consideration in any manner in which they think fit and if the Supervisors raise any sum from the Scheme Consideration before the expiry of the Waiting Period the Supervisors may take into account the effect of having to raise such sum in such manner in deciding whether or not to bring the Waiting Period to an end, PROVIDED THAT the Supervisors may only raise sums from the Scheme Consideration with the consent of the Creditors' Committee, such consent not to be unreasonably withheld. (3) If the Creditors' Committee, acting reasonably, withhold giving consent to the Supervisors raising any sums pursuant to sub-clause 117(2), the Supervisors shall serve a Termination Notice on the Company, the members of the Creditors' Committee and the Scheme Creditors. Clause 111 will thereafter apply. 118. The Company shall not trade or incur any Liability other than as contemplated by and in connection with the implementation of the Scheme whilst the Scheme is continuing. 302

Save in the case of any Distribution Notice or any notice, written communication or document required to be sent pursuant to clause 16 or relating to any appeal against a decision on Scheme Claims pursuant to clauses 17 and 18 or to any adjudication pursuant to Part V, the accidental omission to send any notice, written communication or other document in accordance with clauses 123 to 125 or the non-receipt of any such notice by any Scheme Creditor, shall not affect the provisions of the Scheme. 127.

Property received or receivable by the Company from plc from time to time by virtue of the Company being a creditor of plc (whether pursuant to the plc Scheme, any other scheme of arrangement for plc, any voluntary arrangement for plc or any liquidation of plc or otherwise) shall be available for distribution and shall be distributed by the Company to Admitted Scheme Creditors subject to, at the time, in the manner and on the basis set out in the Scheme. In the light of the position of Ancrane as a Scheme Creditor and a Bondholder and the Ancrane Direction, this may involve successive distributions between the Company and plc, either notional or actual, as provided for in this Scheme and the plc Scheme. THE PLC DISTRIBUTION SUPPLEMENT 27. (1) Sub-clauses 27(2), (3) and (4) shall apply to the Initial Distribution if all of the conditions set out at (a) to (c) inclusive below are satisfied on the Effective Date: (a) the plc Scheme including provisions in the form or substantially the form of that set out in Schedule 2 becomes effective; (b) the plc Scheme supervisors admit the Company's claim against plc pursuant to the plc Scheme; and (c) (i) the Known Claim of Ancrane is Admitted by the Supervisors; or (ii) either (or both) of the Known Claims of the Eurobond Trustee are Admitted by the Supervisors; or (iii) either (or both) of the Known Claims of the Yankee Bond Trustee are Admitted by the Supervisors. (2) To give effect to clause 26 and on the conditions in sub-clause 27(1) being satisfied on the Effective Date, the Supervisors shall agree with the plc Scheme supervisors a distribution model simulating successive distributions to the Company in the plc Scheme and to plc in the Scheme (pursuant to the Ancrane Direction) (using the figures for the Company's claim against plc, Ancrane's claim against the Company as actually admitted by the Supervisors of the respective Schemes and Ancrane's holding of Bonds) in order to produce a net additional amount of Scheme Consideration available for Distribution to Admitted Scheme Creditors with the Initial Distribution (such net additional amount being the "PLC DISTRIBUTION SUPPLEMENT"). The plc Distribution Supplement shall be distributed to Eligible Recipients at the times and in the manner set out sub-clauses 27(3) and 27(4). (3) The Elements of the plc Distribution Supplement shall for these purposes be treated as being made up of two parts as follows: (a) the "KNOWN CLAIMS SUPPLEMENT" which shall be the plc Distribution Supplement less the Reserve Claims Supplement; and (b) the "RESERVE CLAIMS SUPPLEMENT" which shall be the same proportion of the plc Distribution Supplement as the Basic Reserve Claims Segment (which for this purpose shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected and the Distribution Entitlement of the Known Creditor who would have been entitled had its Known Claim been Admitted rather than Conclusively Rejected becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)) is of the Basic Scheme Consideration (which for this purpose 306

III. THE PLC SCHEME -------------------------------------------------------------------------------- shall be calculated after taking into account any decrease in the size of the Basic Known Claims Segment resulting from: (A) Known Claims being Conclusively Rejected resulting in a Rejected Claims Supplement being deducted from the Basic Known Claims Segment pursuant to sub-clause 29(1)(a) and becoming available for distribution to Scheme Creditors in accordance with sub-clause 29(2); and/or (B) Known Claims being Conclusively Rejected resulting in the Distribution Entitlement to which the Known Creditor who would have been entitled had its Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)). (4) (a) The Elements of the Known Claims Supplement shall be distributed to Admitted Known Creditors at the same time as the Initial Distribution. (b) The Elements of the Reserve Claims Supplement shall be distributed to Admitted Reserve Creditors at the same time as the Initial Distribution. (5) (a) For the purposes of Distributions under the Scheme: (i) other than the Initial Distribution; and/or (ii) as regards the Initial Distribution if the provisions of sub-clauses 27(2)-27(4) inclusive do not come into force because one or more of the conditions in sub-clause 27(1) is not satisfied, the Supervisors may agree similar or analogous arrangements to those in sub-clause 27(2) (a "MODEL") with the supervisors of the plc Scheme (if any, or, if none, any other duly authorised representative of plc) where, acting reasonably, the Supervisors consider that to do so shall be in the interests of Admitted Scheme Creditors. (b) If a model is agreed pursuant to sub-clause 27(5)(a) prior to the expiry or termination of the Waiting Period, the equivalent of the plc Distribution Supplement thereby created shall be apportioned in the same manner as provided for in sub-clause 27(3), otherwise no apportionment shall be made. (c) Any supplement arising pursuant to sub-clause 27(5)(a)(ii) which shall be apportioned in accordance with sub-clause 27(5)(b) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (d) Any supplement arising pursuant to sub-clause 27(5)(a)(i) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 27(5)(b) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Receipts in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (e) Any supplement arising pursuant to sub-clause 27(5)(a)(i) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. PLC RECEIPTS 28. (1) As regards: (a) the Initial Distribution if the provisions of sub-clauses 27(2) - 27(4) above do not come into force for any reason; and 307

III. THE PLC SCHEME -------------------------------------------------------------------------------- (b) any Distributions other than the Initial Distribution, in each case, to the extent that relevant similar or analogous arrangements as referred to in clause 27(5) are not agreed in respect of the Company's entitlement to the plc Receipts, Admitted Scheme Creditors shall be entitled to all plc Receipts from time to time which shall be held on trust for Scheme Creditors under the Scheme. (2) If plc Receipts arise pursuant to sub-clause 28(1) prior to the expiry or termination of the Waiting Period, those plc Receipts shall be apportioned in the same manner as provided for in sub- clause 27(3), otherwise no apportionment shall be made. (3) Any plc Receipts arising pursuant to sub-clause 28(1)(a) which shall be apportioned in accordance with sub-clause 28(2) shall be distributed at the same times and in the same manner as provided for in sub-clause 27(4). (4) Any plc Receipts arising pursuant to sub-clause 28(1)(b) prior to the expiry or termination of the Waiting Period shall become available for distribution following apportionment under sub-clause 28(2) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the relevant amount of the supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the relevant amount of the Reserve Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims provided that the costs of making that Distribution would not exceed the value of the Scheme Consideration to be distributed. (5) Any supplement arising pursuant to sub-clause 28(1)(b) after the expiry or termination of the Waiting Period shall be distributed in accordance with the provisions of clause 25. REJECTED CLAIMS 29. (1) Where a Known Claim is Conclusively Rejected before the expiry or termination of the Waiting Period, the Distribution Entitlement to which the Known Creditor would have been entitled, had its Known Claim been Admitted rather than Conclusively Rejected, shall: (a) if the quantum of the Known Claim which is Conclusively Rejected exceeds L250,000,000 (such Distribution Entitlement being a "REJECTED CLAIM SUPPLEMENT"), be deducted from the Known Claims Segment and be apportioned as follows: (i) the "KNOWN REJECTED CLAIM SUPPLEMENT" which shall be the Rejected Claim Supplement less the Reserve Rejected Claim Supplement; and (ii) the "RESERVE REJECTED CLAIM SUPPLEMENT" which shall be the same proportion of the Rejected Claim Supplement as the Basic Reserve Claims Segment (which for this purpose shall be calculated after taking into account any increase in the size of the Basic Reserve Claims Segment resulting from Known Claims being Conclusively Rejected and the Distribution Entitlement of the Known Creditor who would have been entitled had its Known Claim been Admitted rather than Conclusively Rejected becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)) is of the Basic Scheme Consideration (which for this purpose shall be calculated after taking into account any decrease in the size of the Basic Known Claims Segment resulting from: (A) Known Claims being Conclusively Rejected resulting in a Rejected Claims Supplement being deducted from the Basic Known Claims Segment pursuant to sub-clause 29(1)(a) and becoming available for distribution to Scheme Creditors in accordance with sub-clause 29(2); and (B) Known Claims being Conclusively Rejected resulting in the Distribution Entitlement to which the Known Creditor who would have been entitled had its 308

III. THE PLC SCHEME -------------------------------------------------------------------------------- Known Claim been Admitted being deducted from the Basic Known Claims Segment and becoming part of the Reserve Claims Segment pursuant to clause 29(1)(b)). (b) if the quantum of the Known Claim (or part thereof) which is Conclusively Rejected is less than or equal to L250,000,000, be deducted from the Known Claims Segment and form part of the Reserve Claims Segment and therefore not be available for distribution to Admitted Scheme Creditors as a Rejected Claim Supplement pursuant to sub-clause 29(2). (2) A Rejected Claim Supplement shall become available for distribution following apportionment under sub-clause 29(1)(a) and the Supervisors shall promptly issue a Distribution Notice to the Escrow Trustee (with a copy to the Distribution Agent) in respect of the distribution of the amount of the Known Rejected Claim Supplement to which Admitted Known Creditors are entitled pursuant to sub-clause 21(4)(a) and the amount of the Reserve Rejected Claim Supplement to which Admitted Reserve Creditors are entitled pursuant to sub-clause 21(4)(b) to Eligible Recipients in respect of the previously Admitted Claims. (3) For the purposes of distributing the Rejected Claim Supplement; if: (a) the plc Scheme including provisions in the form or substantially in the form of that set out in Schedule 2 becomes effective; (b) the plc Scheme supervisors admit the Company's claim against plc pursuant to the plc Scheme; (c) (i) the Known Claim of Ancrane is Admitted by the Supervisors; or (ii) either (or both) of the Known Claims of the Eurobond Trustee are Admitted by the Supervisors; or (iii) either (or both) of the Known Claims of the Yankee Bond Trustee are Admitted by the Supervisors; and (d) the waiting period under the plc Scheme has not been terminated or expired, the Supervisors may agree similar or analogous arrangements to those in sub-clause 27(2) with the supervisors of the plc Scheme (if any, or, if none, any other duly authorised representative of plc) where, acting reasonably, the Supervisors consider that to do so would be in the best interests of Admitted Scheme Creditors. 309

III. THE PLC SCHEME -------------------------------------------------------------------------------- SCHEDULE 3 KNOWN CLAIMS Following is a list of Scheme Creditors who may have a Scheme Claim. The fact that a claim listed below has been provided for in this Schedule 3 at a certain amount does not mean that the particular claim shall be Admitted at that, or any other, amount. The column headed "Claimed/Estimated Value (including accrued interest) in L's as at the Record Date" provides an indicator of the amount for which each claim may be admitted for the purposes of voting at the meeting of Scheme Creditors convened at the direction of the Court (subject to the remarks set out in the "Remarks" column). Where necessary, to calculate the Claimed/Estimated Value of a claim in sterling, the Exchange Rate on the Business Day falling immediately prior to the Record Date has been applied if necessary. <Table> <Caption> TOTAL AMOUNT AMOUNT CLAIMED/ESTIMATED CLAIMED/ESTIMATED VALUE (INCLUDING VALUE (INCLUDING ACCRUED INTEREST) ACCRUED INTEREST) AS IN L'S AS AT THE CREDITOR AT THE RECORD DATE RECORD DATE REMARKS -------- -------------------- ----------------- ----------------- <S> <C> <C> <C> SYNDICATED BANK DEBT ABN Amro Bank NV US$47,226,487 L43,932,580 L13,920,832 Appaloosa Investment Ltd US$227,732,619 L221,266,466 Partnership L76,545,686 Australia and New Zealand US$91,430,478 L85,053,475 Investment Bank L26,950,731 Banca Antoniana Popolare Veneta US$7,556,238 L7,029,213 London L2,227,333 Banca Monte dei Paschi di Siena US$47,226,487 L43,932,580 L13,920,832 Banca Nazionale del Lavoro SpA US$78,868,233 L73,367,409 L23,247,790 Banca Popolare di Lodi US$15,584,741 L14,497,751 L4,593,875 Banco di Roma US$39,670,249 L36,903,367 L11,693,499 Bank of America N.A.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- NOTES TO THE FINANCIAL INFORMATION 1. ACCOUNTING POLICIES The financial information set out in this Appendix has been prepared in accordance with applicable accounting standards generally accepted in the United Kingdom. The more important Corp Group accounting policies are summarised below to facilitate interpretation of the financial information. BASIS OF COMPILATION Corp was permitted under Section 228 of the Act not to prepare, and did not prepare, consolidated financial statements. The consolidated financial information presented in this report has been derived from plc's audited consolidated financial statements, adjusted for balances and transactions relating to plc and those subsidiaries of plc which do not form part of the Corp Group. BASIS OF PREPARATION -- GOING CONCERN Corp owes approximately L2.1 billion under a syndicated credit facility (the "Bank Facility") which was due for repayment on 25 March 2003. Borrowings under the facility are repayable on demand and no further funds may be drawn under its terms. Corp also has in issue Bonds with a face value of approximately L2.1 billion. plc guarantees Corp's debt obligations under the Bonds and the Bank Facility. As at 30 September 2002, net debt of the Corp Group stood at approximately L3.2 billion. On 29 August 2002, plc announced that non-binding indicative Heads of Terms, which set out the principles for the financial restructuring of Corp and plc, had been concluded with the co-ordination committee of Syndicate Banks and an informal ad hoc committee of Bondholders. On 16 December 2002, plc announced that modifications to the non-binding indicative Heads of Terms had been concluded. The non-binding indicative Heads of Terms envisage that the creditors of Corp and plc, other than certain excluded creditors, will be subject to schemes of arrangement ("Schemes") under which creditor claims will be compromised in consideration for cash, New Shares, and New Notes. As part of the Restructuring Corp will become the listed parent for the Group and, following completion of the plc Scheme, it is currently intended that plc will be liquidated or dissolved. The Restructuring will leave existing plc Shareholders with 0.5 per cent. of the equity in Corp. On 17 March 2003, documentation for the proposed Schemes was filed with the High Court of England and Wales, initiating the final steps towards implementation of the Restructuring. The non-binding indicative Heads of Terms envisage a new capital structure for the Group that is appropriate to the latest business plan developed by the Group. The implementation of this capital structure involves, amongst other things, the payment of L340 million of cash (in addition to L95 million accrued interest on Corp's financial debt, paid in September and October 2002), the issue of New Shares and the issue of New Notes with a face value, using 30 September 2002 exchange rates, of approximately L758 million by Corp to Scheme Creditors through the operation of the Schemes. As part of the arrangements to implement the Restructuring, the majority of the Corp Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the Corp Group's Syndicate Banks and Bondholders (including the bond trustees, but excluding Ancrane, a subsidiary of plc which holds Bonds) and also in favour of one ESOP Derivative Bank who committed to support the proposed Restructuring within the required time period. At 30 September 2002, the balance of this secured cash amounted to L735 million. The Corp Group is dependent on amounts available to it from the secured amounts in order to meet its short-term liquidity needs. Prior to the release of interim security and so long as an enforcement event does not occur, monthly releases from the secured accounts will be allowed in accordance with an agreed cash flow schedule, subject to specified maximum amounts. This agreed cash flow schedule is consistent with the Corp Group's expectations as to its liquidity needs for the period to the end of June 2003. When the non-binding indicative Heads of Terms were announced on 29 August 2002, the Group indicated that the Restructuring was scheduled to be completed by 31 January 2003 (the "Effective Date"). This date was 325

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- extended to 15 March 2003 in December 2002. As a result of the complexity of the Restructuring the Effective Date of the Schemes is now expected to be on or around 19 May 2003. The change to the timing of the Restructuring introduces risks associated with certain financial debt falling due in March 2003. In particular, as noted above, the Bank Facility was due for repayment on 25 March 2003 and interest payments were due on the Yankee Bonds on 17 March 2003 and are due on the Eurobonds on 31 March 2003. Failure to repay the Bank Facility has given rise to direct rights on the part of individual Syndicate Banks to bring actions for recovery of the debt owing to them and will, in addition, after the expiry of a five business day grace period, result in a cross default under the Bonds. In common with the Group's approach to other Scheme claims, pending the outcome of the Schemes, the Group does not intend to make payment in respect of such obligations, in full or in part. The fact of the aforementioned payments falling due represents a risk to the Restructuring, due to consequential legal action which Syndicate Banks or Bondholders who are not supportive of the Restructuring process could take against Corp or plc. However, Corp is of the view that, given the timing associated with any such legal action as well as the likely attitude of the English and New York Courts to a creditor seeking to frustrate the Restructuring (which is intended to be for the benefit of all Scheme creditors), these risks should be manageable. The interim security is subject to various enforcement events, some of which are tied to the prospects of successfully completing the Restructuring in accordance with the non-binding indicative Heads of Terms (and within the agreed timetable, which is currently 30 June 2003). The occurrence of an enforcement event entitles the requisite majority of creditors to block withdrawals from the secured accounts and/or enforce the interim security. Letters of current intention to support the Restructuring and to vote for the Corp and the plc Schemes were obtained from the joint lead co-ordinators of the Syndicate Banks and from each of the members of the Bondholder committee in December 2002. Neither Corp nor plc has received any notice of any changes to this intention. The proposed Restructuring, and Admission of the New Shares, Warrants and New Notes to Listing, are dependent on the Corp Scheme becoming effective. The Corp Scheme will become effective on delivery of the Court's order sanctioning the Corp Scheme to the Registrar of Companies in England and Wales, following, amongst other things, securing the necessary level of support of the Syndicate Banks, Bondholders and other creditors whose claims will be compromised in the relevant creditors' meetings to be held as part of the scheme of arrangement process, as well as the approval of the Court and the granting of a permanent injunction order by the US Bankruptcy Court. Corp considers that, once the Corp Scheme becomes effective, Corp and the Corp Group will have sufficient borrowings and facilities in place to meet their present liabilities and working capital requirements as they fall due for at least a year from the date of the Prospectus, and accordingly the financial information in this Appendix has been drawn up on a going concern basis. Should the Corp Group's Syndicate Banks, Bondholders and other creditors cease to support the Corp Group before the completion of the Restructuring, or should all of the conditions for the Restructuring not be met, there would be no realistic alternative for plc and Corp but to commence insolvency proceedings and the going concern basis of preparation would no longer be applicable; adjustments would be necessary to record additional liabilities and to write down assets to their recoverable amount. It is not practicable to quantify with reasonable accuracy these possible adjustments. ACCOUNTING CONVENTION The financial information has been prepared under the historical cost convention, as modified by the valuation of listed fixed and current asset investments. BASIS OF CONSOLIDATION The consolidated financial statements include the accounts of Corp and its subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation. 326

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- TURNOVER Turnover, excluding VAT, comprises sales to outside customers, and the Corp Group's percentage interest in sales by their joint ventures. The Corp Group records transactions as sales when the delivery of products or performance of services takes place in accordance with the terms of sale. Turnover on long-term contracts is calculated as the proportion of the total contract value based on the ratio of costs incurred to date compared with the total expected costs for that contract. CURRENCY TRANSLATION Transactions denominated in foreign currencies are translated into the functional currency at the rates ruling at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are retranslated at the rates ruling at that date. These translation differences are dealt with in the profit and loss account with the exception of certain gains and losses arising under hedging transactions as described below. Profits and losses of overseas subsidiaries, joint ventures and associates and cash flows of overseas subsidiaries are translated at the average rates of exchange during the period. Net assets are translated at period end rates of exchange. Key rates used are as follows: <Table> <Caption> Average rates Period end rates ---------------------------------------- --------------------------------------- Year ended 31 March Six months ended At 31 March --------------------- 30 September --------------------- At 30 September 2000 2001 2002 2002 2000 2001 2002 2002 ----- ----- ----- ---------------- ----- ----- ----- --------------- <S> <C> <C> <C> <C> <C> <C> <C> <C> US dollar 1.62 1.48 1.43 1.52 1.60 1.42 1.42 1.57 Italian lira 3,015 3,153 3,152 n/a 3,228 3,114 n/a n/a Euro 1.56 1.63 1.63 1.58 1.67 1.67 1.63 1.59 ===== ===== ===== ================ ===== ===== ===== =============== </Table> The differences arising from the restatement of profits and losses and the retranslation of the opening net assets/(liabilities) to period end rates are taken to reserves. ACQUISITION AND DISPOSALS On the acquisition of a business, including an interest in an associated undertaking, fair values are attributed to the Group's share of separable net assets. Where the cost of acquisition exceeds the fair values attributable to such net assets, the difference is treated as purchased goodwill and capitalised in the balance sheet in the year of acquisition. The profit or loss on the disposal or closure of a previously acquired business includes the attributable amount of any purchased goodwill relating to that business not previously charged to the profit and loss account. The results and cash flows relating to a business are included in the consolidated profit and loss account and the consolidated cash flow statement from the date of acquisition or up to the date of disposal. FINANCIAL INSTRUMENTS The Corp Group uses financial instruments, including interest rate swaps, currency swaps and other derivatives, solely for the purposes of raising finance for its operations and managing interest and currency risk associated with the Corp Group's underlying business activities. There is no trading activity in financial instruments. FORWARD FOREIGN EXCHANGE CONTRACTS Forward foreign exchange contracts generally exhibit a high correlation to the hedged items and are designated and considered effective as hedges of the underlying assets, liabilities and firm commitments. Gains and losses on forward foreign exchange contracts which are designated as hedges of assets, liabilities and firm commitments of 327

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- the Corp Group are recognised in the profit and loss account or as adjustments to carrying amounts when the hedged transactions occurs. HEDGES OF THE NET INVESTMENT IN OVERSEAS SUBSIDIARIES The Corp Group's policy has been to finance its activities in the same currencies as those used for its foreign investments in order to hedge foreign currency exposure of net investments in foreign operations. This policy is implemented either by financing in the related currency or using derivatives, such as currency swaps, which provide a synthetic effect of a foreign currency loan, thereby reducing the exchange risk. Exchange gains or losses arising on the hedging borrowings and on the notional principal of currency swaps during their life and at termination or maturity, together with the tax thereon, are dealt with as a movement in reserves, to the extent they offset losses or gains on the hedged investment. In respect of hedges of net investments, the Corp Group enters into tax equalisation swaps, the gains and losses of which are recognised through the statement of total recognised gains and losses (in accordance with the underlying transaction and the tax thereon) with any forward premium or discount recognised over the life of the contract in the profit and loss account. EQUITY FORWARD CONTRACTS The Corp Group has established three trusts for the purchase of shares and share-related instruments for the benefit of employees -- the Marconi Employee Trust ("MET"), the GEC Employee Share Trust ("EST") and the GEC Special Purpose Trust. These trusts are consolidated in the financial statements of the Corp Group. The independent trustee of the MET, Bedell Cristin Trustees Limited ("BCT"), has entered into contracts with three financial institutions (the "Equity Forward Contracts") to hedge the potential cost of the Corp Group's share plans. On or before maturity of the Equity Forward Contracts, the MET may either take delivery of plc Shares at the contracted purchase price (including accrued interest) or settle the contracts for cash for a net amount based on the difference between the plc share price and the contract purchase price (including accrued interest). The obligation to settle the contracts including accrued interest is classified as a provision within the Corp Group's balance sheet. The liability is calculated by taking the number of shares under contract and applying the difference between plc's share price and the contract purchase price per share, adjusted for brokerage costs, on a contract-by-contract basis. No cash is exchanged until the maturity of the contract (or earlier upon either exercises of options by employees or cash settlement of the contracts at the MET's option) unless collateral is required. Where the MET has provided collateral this has been offset against the provision in the consolidated balance sheet. Interest costs on the equity notional amount are calculated at LIBOR plus a margin less dividends, if any, and are accrued on a monthly basis, with a debit to interest and a credit to provisions. INTEREST RATE RISK EXPOSURES The Corp Group hedges its exposure to movements in interest rates associated with its borrowing primarily by means of interest rate swaps and forward rate agreements. Payments and receipts under interest rate swap agreements specifically designated for hedging purposes are recorded in the profit and loss account on an accruals basis. Gains and losses arising on termination of hedging instruments where the underlying exposure remains are recognised in the profit and loss account over the remaining life of the underlying exposure. TANGIBLE FIXED ASSETS Property, plant, machinery, fixtures, fittings, tools and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives from the time they are brought into use. Freehold land does not bear depreciation where the original cost of purchase was separately identified. Provision is made for any impairment. 328

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- Tangible fixed assets are depreciated using the following rates: <Table> <S> <C> Freehold property -- 2 per cent. to 4 per cent. per annum Leasehold property -- over the period of the lease or 50 years for long leases Plant and machinery -- 10 per cent. per annum on average Fixtures, fittings, tools and equipment -- 10 per cent. per annum </Table> LEASED ASSETS Assets held under finance leases and other similar contracts, which confer rights and obligations similar to those attached to owned assets, are capitalised as tangible fixed assets and are depreciated over the shorter of the lease terms and their useful lives. The capital elements of future lease obligations are recorded as liabilities, while the interest elements are charged to the profit and loss account over the period of the leases to produce a constant rate of charge on the balance of capital repayments outstanding. Hire purchase transactions are dealt with similarly except that assets are depreciated over their useful lives. Rentals under operating leases are charged on a straight-line basis over the lease term, even if the payments are not made on such a basis. GOODWILL Purchased goodwill is capitalised and amortised on a straight-line basis over its estimated useful economic life. Each acquisition is separately evaluated for the purposes of determining the useful economic life, up to a maximum of 20 years. The useful economic lives are reviewed annually and revised if necessary. Provision is made for any impairment. RESEARCH AND DEVELOPMENT Expenditure incurred in the period is charged against profit unless specifically chargeable to and receivable from customers under agreed contract terms. STOCKS Stocks are stated at the lower of cost and net realisable value. Provision is made for obsolete, slow-moving or defective items where appropriate. CONTRACTS IN PROGRESS Profit on long-term contracts in progress is taken when a sale is recorded on part-delivery of products or part-performance of services, provided that the outcome of the contract can be assessed with reasonable certainty. Amounts recoverable on long-term contracts, which are included in debtors, are stated at the net sales value of the work done less amounts received as progress payments on account. Excess progress payments are included in creditors as payments received in advance. Cumulative costs incurred net of amounts transferred to cost of sales, less provision for contingencies and anticipated future losses on contracts, are included as long-term contract balances in stock. WARRANTIES Provisions for estimated expenses related to product warranties are made at the time products are sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims. TAXATION Taxation on profit on ordinary activities is that which has been paid or becomes payable in respect of the profits for the period. Deferred taxation is provided in full on timing differences that result in an obligation at the balance sheet date to pay more tax, or a right to pay less tax, at a future date, at rates expected to apply when they crystallise based on current tax rates and law. Timing differences arise from the inclusion of items of income or expenditure in taxation computations in periods different from those in which they are included in the financial 329

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- statements. Deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered. Deferred tax assets and liabilities are not discounted. INVESTMENTS Joint ventures comprise long-term investments where control is shared under a contractual arrangement. The sector analysis of turnover, profit and net assets includes the Corp Group's share of the results and net assets of joint ventures. Associates consist of long-term investments in which the Group holds a participating interest and over which it exercises significant influence. Investments in joint ventures and associates, other than Easynet Group Plc are stated at the amount of the Corp Group's share of net assets, including goodwill at the end of the period derived from audited or management accounts made up to that date. Easynet Group Plc's results are included for the year to 31 December for the Corp Group's results for the three years to 31 March and for the six months to 30 June for the Corp Group's results for the six months to 30 September. Profit/(loss) before taxation includes the Corp Group's share of joint ventures and associates. Other unlisted fixed asset investments are stated at cost less provision for impairment in value. Listed fixed asset investments are stated at market value. Current asset investments are stated at the lower of cost and net realisable value except dated listed securities which are stated at market value. Investments in the shares of plc, held within the EST, the GEC Special Purpose Trust and the MET, are included on the Corp Group balance sheet at cost, less provision for impairment. PENSIONS AND OTHER POST RETIREMENT BENEFITS The operating cost of providing pensions and other post retirement benefits, as calculated periodically by independent actuaries, is charged to the Corp Group's operating profit or loss in the period that those benefits are earned by employees. The financial return expected on the pension schemes' assets is recognised in the period in which they arise as part of finance income and the effect of unwinding of the discounted value of the schemes' liabilities is treated as part of finance costs. The changes in value of the pension schemes' assets and liabilities are reported as actuarial gains or losses as they arise in the consolidated statement of total recognised gains and losses. The pension schemes' surpluses, to the extent they are considered recoverable, or deficits are recognised in full and presented in the balance sheet net of any related deferred tax. SHARE OPTIONS The costs of awarding shares under employee share plans are charged to the profit and loss account over the period to which the performance criteria relate. When share options granted lapse, any associated costs that were treated as costs of acquisition are credited to either goodwill, or to the profit and loss account if there is no remaining goodwill. FINANCE COSTS Finance costs of debt are recognised in the profit and loss account over the term of such instruments at a constant rate on the carrying amount. DEBT Debt is initially stated at the amount of the net proceeds after deduction of issue costs. The carrying amount is increased by the finance cost in respect of the accounting period and reduced by payments made in the period. LIQUID RESOURCES Liquid resources comprise term deposits with an original maturity of generally less than one year and other readily disposable current asset investments. 330

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- The Corp Group has divided its business into two segments: Core and Capital. The Corp Group's Core businesses are the provision of optical networks, broadband routing and switching and broadband access technologies and associated installation, maintenance and other value-added services. Their customer base includes telecommunications companies, and providers of Internet services for their public networks, and to certain large corporations, government departments and agencies, utilities and educational institutions for their private networks. Core activities are divided into Network Equipment, Network Services and Other. Capital comprises the businesses the Corp Group manages for value and ultimately for disposal. The Corp Group's share of joint ventures' profit, turnover and net assets are included under Capital. The net assets of Network Equipment and Network Services cannot be separately identified, as the same assets are, generally, used to generate sales in each of these segments. The results of these segments are separately reportable. Goodwill arising on acquisitions is amortised over a period not exceeding 20 years. Separate components of goodwill are identified and amortised over the appropriate useful economic life. The remaining goodwill on the consolidated balance sheet at 30 September 2002 will be amortised over an average period of approximately seven years. Transactions between Corp Group companies and joint ventures and associates are as follows: <Table> <Caption> Six months Year ended 31 March ended ----------------------------------- 30 September 2000 2001 2002 2002 L million L million L million L million --------- --------- --------- ------------ <S> <C> <C> <C> <C> Sales 65 60 40 16 Purchases (4) (1) (14) -- ========= ========= ========= ============ </Table> The contribution of subsidiaries acquired in each period is as analysed below: <Table> <Caption> Six months Year ended 31 March ended ----------------------------------- 30 September 2000 2001 2002 2002 L million L million L million L million --------- --------- --------- ------------ <S> <C> <C> <C> <C> Turnover 1,254 237 12 -- Operating profit before goodwill amortisation and operating exceptional items 133 10 1 -- ========= ========= ========= ============ </Table> Assets and liabilities arising out of the Retirement Benefit Plan are treated as unallocated net liabilities.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- NOTES (1) The stock write-downs and related costs charged to cost of sales in the year ended 31 March 2002 includes L581 million for obsolescence and slow-moving provisions against a number of product lines, predominantly optical networking products, and L91 million in respect of supplier commitments. (2) In the year ended 31 March 2002 restructuring costs classified within cost of sales includes a charge of L127 million representing additional costs incurred as a consequence of the decision to outsource certain manufacturing operations to Jabil Circuit Inc. ("Jabil"). Under the terms of the agreement, payments of L77 million were made during the year, L19 million provided against stocks and L31 million is expected to be paid in the future. The remaining charge of L31 million in the year ended 31 March 2002 relates to onerous contracts representing certain liabilities to which the Corp Group is committed as a result of the operational restructuring. This includes liabilities, relating to equipment leasing contracts and supply contracts under which it has been agreed to purchase minimum volumes of goods and services which will offer no economic value to the business as a result of its reduced size. In the six months ended 30 September 2002 L24 million was charged to restructuring costs. This relates mostly to additional payments to Jabil, arising in the six month period. (3) In the year ended 31 March 2002, in line with its accounting policies, the Corp Group reassessed the carrying values of goodwill, fixed assets, inventory and debtors. As a consequence of the more uncertain sales outlook and more conservative future assessment of future growth prospects of acquired businesses the Corp Group recorded an exceptional charge of L3,831 million to write down goodwill and tangible fixed assets. The goodwill impairment relates primarily to FORE Systems, Inc., RELTEC Corporation, Metapath Software International, Inc. ("MSI"), Mariposa Technology, Inc., ipsaris Limited (formerly Fibreway Ltd), Systems Management Specialists, Inc. ("SMS") and Albany Partnership Limited ("APT"). In light of declining industry and economic trends on current and expected future operations, the Corp Group reassessed the carrying values of goodwill and tangible fixed assets in the six months ended 30 September 2002. Tangible fixed assets were impaired by L31 million. (4) In the year ended 31 March 2000, the Corp Group incurred restructuring and reorganisation costs relating to restructuring of existing businesses (L43 million) and restructuring of acquisitions (L20 million). In the year ended 31 March 2001, the Corp Group incurred net restructuring and reorganisation costs of L32 million relating to a charge for voluntary redundancy schemes and one-off restructuring costs (L65 million) partially offset by favourable settlements of contract commitments (L33 million). As part of the Corp Group's cost reduction actions, a charge of L324 million was recorded during 31 March 2002 associated with employee severance, site rationalisation costs and other restructuring costs. In the six months ended 30 September 2002 a further charge of L166 million was recorded as part of the Corp Group's cost reduction actions. The site rationalisation costs reflect the charges associated with closing and consolidating various sites around the world as part of the business restructuring and the other restructuring costs represent various other costs associated with the restructuring program. (5) In the year ended 31 March 2000, the Corp Group incurred L43 million in relation to year 2000 costs. During the year ended 31 March 2002 the Corp Group planned to implement a new global IT system. In light of the revised trading outlook and the continued focus on cost reduction, the implementation was terminated. The L75 million charge represents L43 million of capitalised external consultancy costs associated with the implementation, L24 million of hardware and software costs expensed, and L8 million of other associated costs of the project. 337

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- During the six months ended 30 September 2002, the Corp Group was able to revise its previous estimate of the overall costs leading to the release of L7 million from the amounts accrued in the year to 31 March 2002. (6) In light of the declining market and economic trends the Corp Group was experiencing, an exceptional provision against bad and doubtful debts of L150 million was charged during the year ended 31 March 2002. Of this amount, L8 million was paid by the Corp Group's debtors in the six months to 30 September 2002. Operating exceptionals for the Corp Group and joint ventures are analysed by class of business and territory of origin as follows: <Table> <Caption> Six months Year ended 31 March ended --------------------------------- 30 September 2000 2001 2002 2002 L million L million L million L million --------- --------- --------- ------------ <S> <C> <C> <C> <C> Network Equipment and Services (41) (29) (1,312) (187) Other (7) 30 (104) 6 Goodwill impairment -- -- (3,544) -- --------- --------- --------- ------------ (48) 1 (4,960) (181) Capital (5) -- (82) (55) Goodwill impairment -- -- (133) -- --------- --------- --------- ------------ Continuing operations (53) 1 (5,175) (236) Discontinued operations (54) (33) (41) (1) --------- --------- --------- ------------ (107) (32) (5,216) (237) ========= ========= ========= ============ United Kingdom (37) 26 (823) (122) The Americas (29) (18) (407) (97) Rest of Europe (35) (28) (282) (12) Africa, Asia and Australasia (6) (12) (27) (6) --------- --------- --------- ------------ (107) (32) (1,539) (237) Goodwill impairment -- -- (3,677) -- --------- --------- --------- ------------ (107) (32) (5,216) (237) ========= ========= ========= ============ </Table> (B) ASSOCIATES' AND JOINT VENTURES' OPERATING EXCEPTIONALS In the six months ended 30 September 2002, the Corp Group has recorded its share of the operating exceptional charges of its associate, Easynet Group Plc, of L18 million relating to impairment of goodwill and tangible fixed assets and restructuring and reorganisation costs (year ended 31 March 2002 L173 million).

(2) Gains on disposals of subsidiaries and other fixed asset investments in the year ended 31 March 2001 include the disposal of part of the Alstom Holding SA ("Alstom"), Avery Berkel Group and Woods Air Movement Limited Group (note 25(b)). Gains on disposal of subsidiaries and other fixed asset investments in the year ended 31 March 2002 relate to the disposal of Lottomatica S.p.A., General Domestic Appliances Holdings Limited, Siemens Telecommunications Pty Limited, ipsaris Limited and the remaining interest in Alstom. In the six months ended 30 September 2002, the gain on disposal of subsidiaries and other fixed asset investments relates to a L28 million curtailment gain associated with retirement benefits arising mainly from the disposal of the Corp Group's 50 per cent. share in General Domestic Appliances Holdings Limited, L12 million gain on property disposals and a net L9 million charge relating to current and prior period disposals, business closures and other provision movements. (3) Amounts written off investments of L110 million in the year ended 31 March 2001, L200 million in the year ended 31 March 2002 and L40 million in the six months ended 30 September 2002 relate to the reduced market valuations of listed fixed asset investments and provisions for impairment against unlisted investments. 339

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- (4) The merger/demerger items comprise: DIVIDENDS AND CASH RECEIPTS In the year ended 31 March 2000, merger/demerger items comprise L1,409 million of dividends and other cash received by the Group from the defence businesses, Marconi Electronic Systems ("MES"), that were separated from GEC (at the time plc merged with the non-defence business), less the cost of establishing the plc share option plans that were approved at the EGM in November 1999 and other related costs of launching the new Group. The separation of the defence businesses is referred to below as the "MES Transaction". SEPARATION SHARE OPTION COSTS plc developed a number of employee share plans. The Corp Group's normal accounting practice is that the cost of awards to employees that take the form of shares or rights to shares is recognised as an operating expense over the period to which the employees' performance relates. A cost generally arises where the exercise price paid by the option holder is less than either the market value of the shares at the date of grant or the cost of plc satisfying the grant with existing shares, purchased either in the open market or through hedging arrangements. The plc employee share plans launched at the time of the MES Transaction fall outside the normal circumstances and have been treated as exceptional items. The accounting treatment adopted for these plans reflected the nature of the awards which were directly connected with the separation of MES since the awards, and associated costs, would not otherwise have arisen. The estimated cost of awards to Corp Group employees under all plans was L643 million. In the year ended 31 March 2000, there was an exceptional charge of L633 million and the remaining L10 million is shown in note 12(b). The basis of the accounting treatment adopted for the relevant plans is described below. Establishment of plans as part of the MES Transaction. Only employees of the plc Group (including those in acquisitions announced prior to the completion of the MES Transaction) were eligible to participate in the Marconi Launch Share Plan. This plan was designed as a one-off free gift of up to 1,000 free shares for each employee to recognise the contribution the existing workforce had made and to enable them to share some of the benefits of the value created by the separation of MES and the launch of plc. The entitlement to receive the shares was deferred for at least three years and is contingent on the plc share price doubling to L16.03. A charge of L319 million represents the market value at the date of grant of the plc ordinary shares which were expected to be issued under the Marconi Launch Share Plan together with the estimated payroll tax liability. This cost has been recharged to the Corp Group from plc as the participating employees were all within the Corp Group. The grant of additional options (the matching grant) was a one-off event designed to encourage employees to remain with the Corp Group when existing arrangements under the GEC 1997 Executive Scheme became exercisable early as a consequence of the MES Transaction. Optionholders could roll over existing GEC options into new plc options on a value-for-value basis. The matching grant doubled the number of plc options granted to most participants who rolled over their GEC options into plc options or who rolled over their GEC phantom options into plc phantom options. The matching grant was made in direct response to the risk of employees crystallising their gains on share options and was not part of ongoing remuneration. The exercise price of options granted under the matching grant is the market value at the date of grant. In line with the commitment given to shareholders, plc intended to satisfy a proportion of the options under the matching grant by purchasing shares in the market. A charge of L221 million represented the estimated incremental cost to plc (net of the exercise price paid by the optionholders) of purchasing the shares in the market expected to be needed to satisfy these grants, together with the estimated payroll tax liability. As above, this cost has been recharged to the Corp Group from plc as the participating employees were all within the Corp Group. No share options were granted in the period when the MES Transaction was pending since plc did not exist and, with GEC being the listed holding company, new GEC share options would have given inappropriate rights to substitute options for BAE SYSTEMS plc (formerly British Aerospace plc) shares. plc was 340

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- therefore unable to grant options and offered phantom options to employees in lieu of grants under existing GEC option schemes. Following the launch of plc, these phantom options were, where possible, substituted with real options to acquire plc shares. In line with the commitment given to shareholders, substituted options had to be satisfied by purchasing shares in the market. A charge of L93 million represented the estimate of the incremental cost plc incurred as a result of the increase in the cost of purchasing shares in the market from the date the phantom options were granted to the date that hedging this risk on the market could commence. This cost also related to employees within the Corp Group and therefore has been recharged to the Corp Group from plc. For the year ended 31 March 2002, the release of provisions relating to demerger share options arose due to the significant reduction in plc's share price and comprises two elements. L247 million relates to a provision created in respect of the Marconi Launch Share Plan. A further L44 million has been released that relates to provisions in respect of other option schemes created at the time of the MES Transaction. OTHER SEPARATION COSTS/RECEIPTS The gain of L20 million in the year ended 31 March 2001 represented a further settlement received in relation to the MES Transaction in the year. (D) OTHER EXCEPTIONAL CHARGES Amounts written off of L186 million in respect of the funding receivable from plc in the six months ended 30 September 2002 relate to amounts which Corp no longer considers to be recoverable.

As set out in note 4(a) above, in the year ended 31 March 2000, the operating exceptional items primarily related to L63 million of restructuring and reorganisation costs and L43 million of year 2000 costs. The year 2000 costs were substantially all incurred prior to 1 January 2000. In relation to the restructuring of existing businesses and acquisitions, the costs are generally incurred within six to twelve months of the date of the announcement of the Restructuring. Non-operating exceptional cash flows from the disposal of tangible fixed assets and from the sale of interests in subsidiary companies and associates are included in note 23. 341

EQUITY MINORITY INTERESTS Equity minority interests represent the share of the profits less losses on ordinary activities attributable to the interests of equity shareholders in subsidiaries which are not wholly owned by the Corp Group. 9. EQUITY DIVIDENDS During the six months ended 30 September 2002, and the years ended 31 March 2002 and 31 March 2001 no dividends were declared. In the year ended 31 March 2000 L349 million of dividends were declared and paid with L49 million (5.2 pence per share) being an interim dividend and L300 million (30.4 pence per share) as the final dividend. The number of shares are based on the number of ordinary shares in issue following the Restructuring (see Note 10). 10. EARNINGS/(LOSS) PER SHARE Basic earnings/(loss) per share are calculated on the basis of a weighted average of 1,000 million ordinary shares (31 March 2002 1,000 million ordinary shares, 2001 992.8 million ordinary shares, 2000 945.4 million ordinary shares) in issue during the period. The weighted average number of shares is based on the number of ordinary shares in issue following the Restructuring. Earnings/(loss) per share has been calculated on a pro forma basis as this presentation is considered to be more appropriate than presenting earnings/(loss) per share on a historical basis. An adjusted basic (loss)/earnings per share has been presented in order to highlight the underlying performance of the Corp Group, and is calculated as set out in the table below.

A L Thomas was paid a further sum, over and above his basic fee which related to one day's service to plc per week, for each additional day devoted to plc's business. The remuneration detailed above in respect of A L Thomas related to the period from 20 May 2002 being the date on which he was appointed as a Director of plc. The remuneration detailed above in respect of The Rt Hon The Baroness Dunn related to the period up to 11 April 2002 being the date on which she resigned as a Director of plc. (5) Non-Executive Directors do not have service agreements and do not participate in any of the incentive arrangements open to Executive Directors or the Group's pension scheme. (6) All Directors were reimbursed all necessary and reasonable expenses incurred in the performance of their duties. (7) Pension contributions included contributions by the Group to all pension schemes. (B) SHORT-TERM INCENTIVE BONUS In the year ended 31 March 2000, Executive Directors were eligible to participate in a short-term incentive plan. The plan paid bonuses only when an economic value added target (based on profitable growth) was met. The payment for 'on-target' performance was 25 per cent. of basic salary for Executive Directors and was subject to a maximum payment in a single year of 50 per cent. In considering the payment of short-term incentive bonuses, personal performance was also taken into account. During the year ended 31 March 2000, bonuses were paid at the rate of 50 per cent; no amounts were carried forward. In the year ended 31 March 2001, Executive Directors continued to be eligible to participate in the short-term incentive plan, however no bonuses were awarded during the year. In the year ended 31 March 2002, plc's Remuneration Committee approved the implementation of a short-term incentive plan for Executive Directors with maximum payment of 100 per cent. of salary, although owing to subsequent events, no such plan was implemented and no short-term incentive payments were made in the year ended 31 March 2002. In the six months ended 30 September 2002, Executive Directors participated in an exceptional incentive plan with payment related to successful completion of the Restructuring of the plc Group. The maximum payment under this plan is 150 per cent. of salary. Executive Directors also participate in a quarterly incentive plan with payments due for the achievement of targets for the generation of total cash. Payment relating to the six months 348

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- ending 30 September 2002, has not been made under this plan and it is anticipated that Executive Directors will agree to waive entitlement to these payments on entering into new employment agreements with Corp. (C) LONG-TERM INCENTIVE SCHEMES Aggregate emoluments detailed above do not include any amounts in respect of long-term incentive schemes. plc operates a number of schemes as described below. At a meeting held on 3 November 1999, shareholders approved the introduction of a number of share plans following the reconstruction of GEC and the Listing of plc on 30 November 1999. Two main discretionary plans were approved -- the Marconi 1999 Stock Option Plan and the Marconi Long-Term Incentive Plan with the Executive Directors eligible to participate in both plans. In addition, shareholders approved the introduction of the Marconi UK Sharesave Plan and the Marconi Launch Share Plan in which Executive Directors and all eligible employees may participate. Full details of options granted to Executive Directors under these plans are set out below. In summary, options may be granted under the Marconi 1999 Stock Option Plan for a period of up to ten years from 30 November 1999. Options granted under the plan prior to 18 July 2001 become exercisable three years from the date of grant, provided the performance condition has been met, that is the percentage increase in plc's earnings per share must be equal to or greater than the percentage increase in the Retail Prices Index plus 3 per cent. per annum. Thus the shortest period over which the performance target can be satisfied is three financial years from the date of grant; if the target is not satisfied after this period, it can be retested over the four financial years from the date of grant, and so on. At the July 2001 plc annual general meeting, shareholders approved amendments to the plan rules giving the plc Remuneration Committee discretion to grant options which become exercisable over varying periods of time and which are subject to performance conditions appropriate to the markets in which plc operates. In previous years, plc's policy on the granting of options has been to make phased awards to key employees, based on business and personal performance, with the value of options granted normally ranging from 50 per cent. to 150 per cent. of basic salary per annum. Reductions in plc's share price meant that option holdings built up over a number of years (with the minimum exercise value of any option granted under the plan having been L6.70) had lost any value as an incentive, and that grants based on these multiples of salary would result in an unacceptable level of dilution. In granting options to around 600 key executive, technical, and sales and marketing staff (including Executive Directors) in November 2001, the Remuneration Committee sought to balance an appropriate level of dilution with the need to provide a meaningful level of incentive. In exercising its discretion in respect of performance targets, the Remuneration Committee recognised the need for plc to achieve its near-term objectives in order to deliver longer-term performance. Of each option granted in November 2001, 50 per cent. is subject to the achievement of targets for the reduction in plc's net debt, and 50 per cent. subject to plc's Total Shareholder Return ("TSR") compared to that of FTSE 100 companies. None of this 50 per cent. becomes exercisable if plc's TSR is the same as that of the company at the 50th percentile, all becomes exercisable at the 75th percentile, with progressive increases between these points. In order to provide a progressive incentive, options become exercisable, subject to the achievement of the performance conditions, over four years. Under the Long-Term Incentive Plan, each year Executive Directors can receive an award of up to a maximum of 50 per cent. of basic salary, subject to satisfaction of demanding corporate performance over the three years from the date of award. After three years from the date of award, provided plc's TSR is in the top 50 of the FTSE 100 index, participants may be granted a nil cost option to acquire plc Shares. To the extent that the awards vest, the nil cost options will normally be exercisable in three tranches, one third immediately upon vesting, one third on the first anniversary and one third on the second anniversary of the date of grant. On 30 November 1999, the then Executive Directors participated in the plan for the first time; their nil cost options under the plan were to vest in two annual tranches from July 2002; the shorter performance period and the accelerated vesting of the tranches reflected the fact that the grant of these awards was delayed by reason of the transaction with British Aerospace plc (now known as BAE SYSTEMS plc). The employment of those Executive Directors was subsequently terminated and no options were granted. Current Executive Directors first received awards in April 1998 and details of their conditional awards are contained in the table below. 349

(D) DIRECTORS' INTERESTS The plc Group has previously operated a personal shareholding policy in order to assist in further aligning the interests of executives and shareholders. The policy requires Executive Directors to build up, over a period of time, a target shareholding of plc Shares with a market value equal to three times annual basic salary. The policy was not applied to the November 2001 option grant as it was not considered to be practical to do so, given plc's share price. The Directors' interests as defined by the Act (which include trustee holdings and family interests including holdings of minor children) in shares of plc and its Subsidiaries are as follows: (a) Ordinary shares <Table> <Caption> As at As at As at As at 31 March 31 March 31 March 30 September 2000 2001 2002 2002 Beneficial Beneficial Beneficial Beneficial ---------- ---------- ---------- ------------ <S> <C> <C> <C> <C> Sir William Castell 10,000 10,000 10,000 10,000 The Rt Hon The Baroness Dunn 10,000 10,000 10,000 n/a M J Donovan 23,232 67,601 169,670 169,670 Sir Roger Hurn 11,450 31,450 n/a n/a J C Mayo 164,340 164,343 n/a n/a R I Meakin 11,050 20,303 n/a n/a M W J Parton 28,776 28,860 128,122 128,122 Sir Alan Rudge 10,000 10,000 20,000 20,000 Hon Raymond G H Seitz 11,027 11,095 11,099 11,099 Lord Simpson 106,606 133,606 n/a n/a N J Stapleton 13,752 13,572 21,572 21,572 D C Bonham n/a n/a 156,000 156,000 S Hare n/a n/a 30,121 30,121 A L Thomas n/a n/a n/a -- ========== ========== ========== ============ </Table> --------------- NOTES (1) None of the Directors held any non-beneficial interests in the shares of GEC or plc during the periods above. 350

(2) The Executive Directors, along with those employees remaining in the plc Group, were given the opportunity to exchange their GEC options for plc options on a value-for-value basis and all of the Executive Directors elected to exchange their options. The exchange of options was effected on 29 November 1999. (3) The terms of Lord Simpson's service contract with GEC made certain provisions for awards of shares to be made to him under the rules of the GEC Employee Share Plan and the grant of a notional option. Upon the reconstruction of GEC, the service contracts of the Executive Directors were reviewed and the Remuneration Committee decided, taking account of the restriction with regard to Lord 351

In exchange for the GEC share award and notional option held by Lord Simpson each over 625,000 GEC shares at L3.84 per share, Lord Simpson received, subject to a limitation agreed by the Remuneration Committee in respect of the notional option, options over plc Shares, details of which are set out in the table above. (4) Although the options granted by GEC became exercisable immediately prior to the Listing of plc, no options were exercised by any of the Directors. J C Mayo, R I Meakin and Lord Simpson each undertook not to exercise their options within a period of one year from the date of listing.

(2) The mid-market price of a plc Share as at 30 September 2002 was 1.45 pence with a range during the period of 1.27 pence to 12.55 pence. (3) All options have exercise prices that exceed the market price of a plc Share as at 30 September 2002, other than nil cost options granted under the Marconi Launch Share Plan (1,000 shares at nil cost) and the Marconi Long-Term Incentive Plan. (E) RETIREMENT BENEFITS All Executive Directors are members of (are entitled to be members of) the Group's approved pension scheme, the GEC 1972 Plan (the "UK Plan"). Members contribute at the rate of 3 per cent. of salary subject to limits imposed by the Inland Revenue. plc contributions made during the six months ended 30 September 2002 amounted to 14.2 per cent. of salary, similarly restricted (year ended 31 March 2002 6.6 per cent., 2001 6.6 per cent., 2000 6.6 per cent.). The increase in contributions resulted from an interim actuarial valuation of the UK Plan, which was undertaken as at 30 September 2001, following the sale of part of the business of plc. The results of this valuation revealed that there was a deficit in the UK Plan at that time of L137 million and, on the advice of the actuary, the rate of employers' contributions was increased. Funded unapproved retirement benefit schemes ("FURBS") have been established for two of the current Directors -- M J Donovan and M W J Parton. In the case of M W J Parton, gross contributions to the FURBS are paid at the rate of 35 per cent. of basic salary, with 21 per cent. being paid into the FURBS and the remaining 14 per cent. direct to M W J Parton. The accumulated balance in the FURBS, including investment returns, is payable to M W J Parton on retirement. M J Donovan's FURBS is funded on a defined benefit basis, with projected benefits (including under other plans) of two-thirds of his final pensionable salary. The current contribution rate (to be reviewed in May 2003) is 39 per cent. of his base salary (although while M J Donovan is posted to the US, the rate is 46 per cent., owing to local tax legislation). The pension will be made up from M J Donovan's benefits under the UK Plan, the FURBS, two BAE pension plans and any other retained benefits he may have. FURBS contributions for M J Donovan are paid into the FURBS and to M J Donovan himself in the 353

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- ratio of 60:40 (or as necessary under US tax law). This is because the contributions are taxable benefits, so the payment to M J Donovan is to offset the higher income tax charge for which he is liable. The FURBS documents oblige Corp to fund an unapproved life assurance scheme, which is to provide a lump sum on death in service of four times basic salary and a widow's pension of four-ninths of final pensionable salary. An additional contribution of L240,000 was paid into M J Donovan's FURBS in 2002 to make good a deficit shown by its last actuarial valuation. The normal retirement age is 62 for Executive Directors. If M J Donovan retires on or after his fifty-fifth birthday, there will be no actuarial reduction in the value of his benefits. In the event of cessation of employment before normal retirement age, or at retirement age each of the Directors is entitled to the amount held in the FURBS established for him. FURBS were also established for former Directors -- Lord Simpson, R J Meakin and J C Mayo. In the case of Lord Simpson, the final contribution to his FURBS was made in October 2001 and no further contributions are due from plc. In the case of R J Meakin, a final contribution was paid by plc on 14 January 2003. In the case of J C Mayo, contributions to fully fund his FURBS were paid on 5 July 2002. There is an ongoing obligation to review the funding level each year for the FURBS for current employees which may result in additional contributions being required by plc. The Remuneration Committee has reviewed the cost of FURBS arrangements for the Executive Directors and has decided that it is not appropriate to plc's changed circumstances. Consequently, plc has sought to change the basis of the FURBS it provides for the current Executive Directors. With effect from 1 April 2002, the FURBS for M W J Parton was changed to a defined contribution basis as described below. For the six months ended 30 September 2002 the only current director who has a defined benefit FURBS was M J Donovan. His FURBS is disclosed in accordance with the Actuarial Guidance Note GN11. This is consistent with the treatment of benefits accrued under the UK Plan. In accordance with the requirements of the Listing Rules, the disclosures required for each period are set out below. The figures for pensions shown below are the contributions paid by the Group in respect of each Director. In addition to this disclosure, the Directors' remuneration table above also discloses within pension contributions, the contributions paid by plc in respect of these FURBS arrangements and all other pension arrangements including the UK Plan. The pension benefits earned by the Directors of plc under the UK Plan are: AS AT 31 MARCH 2000 <Table> <Caption> Cost of pension benefits accrued Increase in during the period Accumulated total Length of pensionable accrued pension net of member's accrued pension as Name of service during the period contributions at 31 March 2000 Director years L000 L000 L000 -------- --------------------- ----------------- ----------------- ------------------ <S> <C> <C> <C> <C> M J Donovan 1 1 2 2 J C Mayo 2 1 2 4 R I Meakin 3 1 11 5 M W J Parton 9 1 1 14 Lord Simpson 3 1 10 5 ===================== ================= ================= ================== </Table> 354

(2) The increase in accrued pension during the period excludes any increase for inflation. (3) The cost of pension benefits accrued during the period net of member's contributions has been calculated on the basis of actuarial advice in accordance with Actuarial Guidance Note GN11. The cost of pension benefits accrued during the period net of member's contributions is a measure of the capital cost of providing future pension payments and accordingly is a liability of the Group's pension arrangements and not a sum paid or due to the Directors of plc. 355

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- (4) The ability of plc to satisfy pension obligations for Directors subject to the earnings cap from plc's approved pension scheme, rather than unapproved schemes, is influenced by benefits payable from other approved pension schemes from their previous employment. In respect of M W J Parton, benefits accrued under approved plans from previous employment were lower than anticipated prior to the period ended 31 March 2002. Consequently, a higher portion of his accrued pension benefit can be paid from the UK Plan, as opposed to FURBS arrangements and his accrued pension under the UK Plan is increased in the period ended 31 March 2002 and, as a result his entitlement under the FURBS arrangements for that period is reduced by a corresponding amount. With effect from 1 April 2002, M W J Parton's FURBS entitlements are provided on a defined contribution basis, with benefits accrued under approved plans payable in addition. (5) Members of the UK Plan have the option to make additional voluntary contributions; neither any additional voluntary contributions nor the resulting benefits are included in the above table. (6) In the event of death in service, a lump sum of four times pensionable salary, plus additional benefits for a surviving spouse and/or children, inclusive of any death benefits arising from the UK Plan, will be held in trust for the benefit of the dependents of serving Directors who are members of the UK Plan. In previous periods, the contributions made to the Directors' FURBS have been disclosed on a defined contribution basis. For the six months ended 30 September 2002 and the year ended 31 March 2002, owing to certain guarantees from plc which underpin the Directors' pension entitlements, Corp believes that it is more appropriate to disclose certain of the FURBS arrangements as a defined benefit basis in accordance with Actuarial Guidance Note GN11. This is consistent with the treatment of benefits accrued under the UK Plan. Comparative disclosures have not been provided for earlier periods, as it is not practical to do so. The pension benefits earned by the Directors of plc under the FURBS arrangements are: AS AT 31 MARCH 2002 <Table> <Caption> Cost of pension Accumulated benefits accrued total accrued Length of Increase in during the period pension at pensionable accrued pension net of member's 31 March service during the period contributions 2002 Name of Director years L000 L000 L000 ---------------- ------------- ----------------- ----------------- ------------- <S> <C> <C> <C> <C> M J Donovan 3 10 54 68 J C Mayo* 3 25 107 159 R I Meakin* 5 7 66 102 M W J Parton 11 12 58 52 ============= ================= ================= ============= </Table> --------------- * at the date of cessation of employment.

(2) The increase in accrued pension during the period excludes any increase for inflation. (3) M J Donovan and M W J Parton became Directors during the year ended 31 March 2000. Contributions of L13,212 and L35,625 were paid into their FURBS respectively, in respect of the period during the year ended 31 March 2000 in which they were Directors of the Group. No entry is shown for Lord Simpson in the pension benefits tables above as, in his case, his defined contribution entitlement due under the FURBS was completed in the year ended 31 March 2002 by the payment of L212,000 to the trustees of the FURBS. Lord Simpson resigned as a Director of plc on 4 September 2001. J C Mayo resigned as a Director of plc on 6 July 2001 and a payment of L257,000 was paid to his FURBS in respect of pensionable service for the period to 5 July 2002. R I Meakin resigned as a Director of plc on 1 March 2002. A contribution of L568,000 became due immediately. L290,000 was paid to his FURBS in the period up to 30 September 2002 and a final contribution of L278,000 was paid by plc on 14 January 2003. A further non-pensionable allowance of L185,000 was paid directly to R I Meakin in final settlement of his FURBS entitlements. (4) The contributions are determined each period based on actuarial advice to be sufficient to meet the obligations. Periodically the contributions are reviewed by the actuary. An actuarial valuation of M J Donovan's FURBS, disclosed a deficit of L240,000. A contribution of L240,000 was therefore paid by plc into the FURBS in addition to regular contributions with a further non-pensionable allowance of L228,284 being paid directly to M J Donovan. The accumulated accrued pension shown for M J Donovan for the period to 31 March 2002 was based on information available to the actuary at the date of the calculation. Subsequently more up-to-date information was acquired relating to benefits payable to M J Donovan from previous employments. The effect of allowing for the revised figures would be to show a lower accumulated accrued pension at 31 March 2002 of L64,000. In calculating the disclosure at 30 September 2002 the actuary has taken into account the additional information. (5) With effect from 1 April 2002, M W J Parton's FURBS was amended from a defined benefit FURBS to a defined contribution FURBS. As part of this process, plc agreed to pay contributions in accordance with the following table to meet a deficit on the now discontinued defined benefit basis in addition to the normal contributions. In the event that M W J Parton's employment is terminated, any payments which have not been made on or before the date of termination will become due immediately: <Table> <Caption> FURBS Non-pensionable contribution allowance On or before L000 L000 ------------ ------------ --------------- <S> <C> <C> 15 April 2003 88 59 15 July 2003 88 59 15 October 2003 88 59 15 January 2004 88 59 ============ =============== </Table> 357

Following the continued difficult market conditions, plc announced expectations of a delay in market recovery beyond the end of 2003; significant changes to the Corp Group forecasts have been made, and a further review has been undertaken at 30 September 2002. The average discount rate applied to the future cash flows is 15 per cent. and is based upon a weighted average cost of capital percentage. The results of the review indicated that no further impairment charge in respect of goodwill was necessary for the 6 months to 30 September 2002. However, due to the significant uncertainties over the timing and extent of any recovery in the telecommunications market, Corp acknowledges that it is likely to have to continue to review its assumptions against future performance. 359

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- During the six months to 30 September 2002, goodwill on Easynet Group Plc was impaired by L27 million and an amortisation charge of L5 million was incurred. OTHER INVESTMENTS Additions during the year ended 31 March 2001 consisted primarily of NetDecisions Holdings Limited (L49 million) and Arraycomm, Inc. (L28 million). Disposals during the year ended 31 March 2001 consisted of part disposals of Alstom SA (L610 million) and Lagardere SCA (L9 million). Disposals during the year ended 31 March 2002 consisted primarily of the remainder of Alstom SA (L236 million) and Lagardere SCA (L73 million). MARKET VALUES Listed fixed asset investments are stated at market value, as follows: <Table> <Caption> As at 31 March As at ---------------------- 30 September 2001 2002 2002 L million L million L million --------- --------- ------------ <S> <C> <C> <C> Alstom -- listed overseas 236 -- -- Other investments -- listed in the United Kingdom 20 19 8 Other investments -- listed overseas 73 -- -- ========= ========= ============ </Table> The Corp Group has not provided for tax which could arise if these investments were realised at the values stated. The Corp Group estimates that the tax charge arising would be Lnil for the six months ended 30 September 2002 (year ended 31 March 2002 Lnil, 2001 L6 million.). During the year ended 31 March 2000 the Corp Group acquired a 27 per cent. stake in Atlantic Telecom Group plc. During the year ended 31 March 2001, Atlantic Telecom Group plc purchased First Telecom Group plc for L520 million through a new share issue. The effect of this transaction was to dilute the Corp Group's stake to below 20 per cent. After careful review of the Corp Group's involvement in Atlantic Telecom Group plc it did not believe that it exercised significant influence and, accordingly, treated the investment as a listed fixed asset investment from the date of acquisition. After careful review of the Corp Group's involvement in Alstom, the Corp Group did not believe that it exercised significant influence. On 9 February 2001 the Corp Group, in conjunction with Alcatel SA, carried out a placement of an equal number of Alstom shares. The effect of the placement was to further reduce the Corp Group's shareholding in Alstom to below 10 per cent. from 24 per cent. Accordingly, Alstom has been treated as a listed fixed asset investment until disposal on 19 June 2001. On 26 September 2001, the Corp Group sold its remaining investment in Lagardere SCA. On 1 February 2002, the Corp Group acquired an approximate 9 per cent. shareholding in Bookham Technology plc. The aggregate historical cost of the listed fixed asset investments was L49 million at 30 September 2002 (31 March 2002 L49 million, 2001 L165 million). At 27 March 2003 the market value of the investments shown above was in aggregate L11 million. 363

POST RETIREMENT BENEFITS The Corp Group operates defined benefit pension plans in the UK, other European countries and the US and post-retirement benefit plans in the US. The most significant plan is the GEC 1972 Plan ("UK Plan") in the UK. A full actuarial valuation for the UK Plan was carried out as at 5 April 2002 and a valuation for accounting purposes was carried out as at 30 September 2002 by independent qualified actuaries. As a result of the separation of Marconi Electronic Systems ("MES") in November 1999, the MES employees ceased to participate in the UK Plan and, on 6 April 2000, were transferred to a new BAE SYSTEMS plc pension scheme (the BAE SYSTEMS plc 2000 Pension Plan -- the "BAE Plan") providing identical benefits to the UK Plan. A share of the UK Plan's assets were transferred to the corresponding new BAE Plan, proportional to the share of the total UK Plan's liabilities as at 6 April 2000 that were attributable to the MES members, based on actuarial calculations performed as at 6 April 2000. For the US plans, full valuations were carried out at dates between 1 January 2001 and 31 March 2002 and updated as applicable to 30 September 2002 by independent qualified actuaries. For the other European unfunded plans, valuations were carried out for accounting purposes at 30 September 2002 by independent qualified actuaries. The contributions made to the plans in the six months ended 30 September 2002 totalled L19 million (year ended 31 March 2002 L36 million, 2001 L46 million). For the unfunded pension plans and the post retirement medical plans, payments are made when the benefits are provided. Since 6 April 2002 the contributions to the UK Plan were 14.2 per cent. of pensionable pay, reducing to 8.2 per cent. on 1 November, 2002. Other than Italy, where approximately 7.4 per cent. of pensionable pay is accrued, 385

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- the Corp Group is not making significant contributions to its overseas funded plans due to the surpluses in the schemes at the time of the last funding valuation. The Corp Group operates defined contribution schemes in addition to the defined benefit schemes listed. Contributions to these schemes amounted to L1 million for the six months ended 30 September 2002 (year ended 31 March 2002 L25 million, 2001 L20 million). Contributions to both the defined benefit and defined contribution schemes in the year ended 31 March 2000 were L26 million. The major assumptions used by the actuaries to determine the liabilities for the significant defined benefit plans are set out below: <Table> <Caption> At 30 September At 31 March 2000 At 31 March 2001 At 31 March 2002 2002 ---------------------- ---------------------- ---------------------- ---------------------- Rest of the Rest of the Rest of the Rest of the UK world UK world UK world UK world (% pa) (% pa) (% pa) (% pa) (% pa) (% pa) (% pa) (% pa) ------ ------------- ------ ------------- ------ ------------- ------ ------------- <S> <C> <C> <C> <C> <C> <C> <C> <C> AVERAGE ASSUMPTIONS USED: Rate of general increase in salaries 5.00% 4.63% 4.50% 4.92% 4.75% 4.23% 4.50% 3.0%-5.1% Rate of increase in pensions in payment 3.00% 2.00% 2.50% 2.00% 2.75% 1.50% 2.50% 1.5%-2.5% Rate of increase for deferred pensioners 3.00% N/A 2.50% N/A 2.75% N/A 2.50% N/A Rate of credited interest 6.00% N/A 5.75% N/A 5.50% N/A 4.00% N/A Discount rate applied to liabilities 6.00% 7.64% 6.00% 7.49% 6.00% 6.85% 5.25% 5.5%-6.5% Inflation assumption 3.00% 2.44% 2.50% 2.44% 2.75% 2.25% 2.50% 1.5%-2.5% Expected healthcare trend rates N/A 7% pre 65, N/A 7% pre 65, 9% N/A 6% pre 65, N/A 7% pre 65, 7% 10% post 65 post 65 7.5% post 65 post 65 reducing to reducing to reducing to reducing to 5% after 2005 5% after 2005 5% after 2005 5% after 2005 ====== ============= ====== ============= ====== ============= ====== ============= </Table> The UK Plan provides benefits to members on the best of three bases. One of these bases is a money purchase underpin in which credited interest is applied to a percentage of members' contributions. The assumption reflects the UK Plan Trustee's practice of declaring credited interest. The interest rate has been revised between 31 March 2002 and 30 September 2002 so that the level of credited interest is not as high as previously. The discretionary level of credited interest has been treated as a constructive obligation. 386

For all periods other than the year ended 31 March 2000, actual investment returns in the UK and US plans fell well below expected investment returns resulting in substantial asset losses. The second largest element has been the gains and losses resulting from changes in assumptions underlying the present value of the plans' liabilities. These have resulted principally from the changes in assumptions used at each period end for the UK Plan. At 31 March 2001, the assumed rates of increase in inflation, salary and pension increases fell compared with those used at 31 March 2000. These changes resulted in a decrease in the present value of the liabilities at 31 March 2001 compared with those calculated at 31 March 2000, and this gave rise to a gain over the period. The assumptions were all increased at 31 March 2002 and again at 30 September 2002, resulting in an increase in the present value of liabilities at both period ends compared with those calculated at the end of the prior periods, and this gave rise to a loss over both periods. 390

FINANCIAL INSTRUMENTS TREASURY POLICIES AND ORGANISATION plc's Board of Directors has approved the policies and procedures of the Corp Group's treasury function and assigned the co-ordination of the Corp Group's treasury activities to the Corp Group. It does not operate as a profit centre. Treasury advises operational management on treasury matters and undertakes all derivative transactions except certain forward exchange contracts relating to the hedging of foreign currency transaction exposures arising in the operating businesses which have in the past been managed by those operating units as described below. All treasury related transactions undertaken by our operating businesses are required to be in accordance with guidelines laid down by our central treasury function and comply with the group risk management policies. Short-term debtors and creditors have been excluded from all disclosures within this note except the currency profile. 394

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- FINANCIAL INSTRUMENTS The Corp Group uses financial instruments, including derivatives (principally interest rate swaps, cancellable interest rate swaps, currency swaps and forward foreign currency contracts) to manage interest rate and currency risk exposures. It is the Corp Group's policy that there is no trading in financial instruments, and all financial instruments are used for the purpose of financing or hedging identified exposures of the Corp Group. The main risks faced by the Corp Group in the financial markets are liquidity risk, interest rate risk, foreign currency risk, counterparty risk and share price risk. The plc Board reviews and agrees policies for managing each of these, which are summarised below. LIQUIDITY RISK The Corp Group has funded its activities through cash generated from its operational activities, the proceeds of disposals, bank borrowings and the debt capital markets. <Table> <Caption> At 31 March At --------------------- 30 September 2001 2002 2002 L million L million L million --------- --------- ------------ <S> <C> <C> <C> Gross borrowings 3,677 4,615 4,281 ========= ========= ============ </Table> The Corp Group's gross borrowings as at 31 March 2001 reflected increased levels of working capital as the businesses grew, including higher than normal inventory of optical components together with increased net capital expenditure of the growth businesses. The Corp Group's gross borrowings as at 31 March 2002 reflected operating cash outflows and financing transactions in the first half of the year, offset by debt reductions funded from disposal proceeds. The Corp Group's gross borrowings as at 30 September 2002 reflected the repayment of local borrowings in Italy as a result of the disposal of the Strategic Communications business, and a substantial reduction in the sterling value of the US$ denominated debt due to foreign exchange movements. The Corp Group's net debt was L3,219 million at 30 September 2002 (31 March 2002 L3,254 million, 2001 L3,308 million). <Table> <Caption> At 31 March At --------------------- 30 September 2001 2002 2002 L million L million L million --------- --------- ------------ <S> <C> <C> <C> Net debt as reported in the reconciliation of net cash flow to movements in net monetary debt (3,782) (3,335) (3,514) Net creditor with plc and fellow subsidiaries of the plc Group 474 81 295 --------- --------- ------------ Net debt as reported in accordance with FRS13 disclosures (3,308) (3,254) (3,219) ========= ========= ============ </Table> 395

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- The Corp Group's cash and liquid resources are analysed as follows: <Table> <Caption> At 31 March At --------------------- 30 September 2001 2002 2002 L million L million L million --------- --------- ------------ <S> <C> <C> <C> Sterling 99 277 149 US dollars 66 726 508 Euro 124 239 352 Other 80 119 53 --------- --------- ------------ 369 1,361 1,062 ========= ========= ============ </Table> At 30 September 2002, the Corp Group had E3.6 billion (31 March 2002 E3.6 billion, 2001 E7 billion) of syndicated bank facilities. At 30 September 2002 and 31 March 2002 all these syndicated facilities were payable on demand. As previously disclosed, the majority of the Corp Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the Corp Group's Syndicate Banks and Bondholders (including the Bond trustees) and also in favour of one of the ESOP Derivative Banks. The secured accounts were created at the end of April 2002 in accordance with the previously disclosed lock box arrangements entered into in favour of the Syndicate Banks and Bondholders. The interim security arrangements contemplated by the Heads of Terms were implemented on 13 September 2002, and the balance of this secured cash amounted to L735 million at 30 September 2002. The Corp Group is dependent on amounts available to it from the secured amounts in order to meet its short-term liquidity needs. Prior to the release of interim security and so long as an enforcement event does not occur, monthly releases from the secured accounts will be allowed in accordance with an agreed cash flow schedule, subject to specified maximum amounts. This agreed cash flow schedule takes account of the Corp Group's anticipated cash inflows and outflows, and is consistent with the Corp Group's expectations as to its liquidity needs for the relevant period. Further details on the interim security and the Corp Group's liquidity risk are set out in note 1. INTEREST RATE RISK It has in the past been Corp Group policy to maintain at least 50 per cent. of debt at fixed rates of interest. The term structure of interest rates was managed in observance of this policy using derivative financial instruments such as interest rate swaps. However, due to the Restructuring process described above, this has been superseded by the requirement to manage immediate liquidity including the cancellation of all outstanding derivatives positions. Consequently, during the first half of the financial year, out-of-the-money interest rate swap arrangements with fair value of L54 million were converted to new loan agreements, and cash proceeds of L8 million were received from unwinding in-the-money interest rate swap arrangements. At 30 September 2002, 53 per cent. (31 March 2002 57 per cent., 2001 74 per cent.) of the Corp Group's interest-bearing borrowings were at fixed rates after taking account of interest rate swaps. Of this total, 30 per cent. (31 March 2002 43 per cent., 2001 55 per cent.) were at fixed dollar rates of interest and 22 per cent. (31 March 2002 14 per cent., 2001 18 per cent.) were at fixed Euro rates of interest. In the six months ended 30 September 2002, the average interest rate received on cash and liquid investments was approximately 2.4 per cent. per annum. The largest proportion of investments was in US$ deposits. The Corp Group held an average of approximately $850 million in US$ deposits, earning an average interest rate of 1.75 per cent. per annum. In the year ended 31 March 2002, the average interest rate received on cash and liquid investments was approximately 5.2 per cent. per annum. The largest proportion of investments was in US dollar deposits -- the 396

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- Corp Group held an average of approximately $400 million in US dollar deposits, earning an average interest rate of 1.9 per cent. per annum. These US dollar deposits match in part the US dollar borrowings referred to below. In the year ended 31 March 2001, the average interest rate received on cash and liquid investments was approximately 4.5 per cent. per annum. The largest proportion of investments was in sterling deposits -- the Corp Group held an average of L152 million in sterling deposits, earning an average interest rate of 5.9 per cent. per annum. Due to the proportion of fixed rate debt, the Corp Group's interest charge has limited exposure to interest rate movements. Consequently an increase in market interest rates of one percentage point would have increased loss before taxation in the six months ended 30 September 2002 by approximately L5 million (year ended 31 March 2002 L12 million, 2001 L4 million). FOREIGN EXCHANGE RISK The Corp Group is exposed to movements in foreign exchange rates against sterling for both trading transactions and the translation of net assets and the profit and loss accounts of overseas subsidiaries. The main trading currencies of the Corp Group are the US dollar, sterling and the Euro. The foreign currency management policy of the Corp Group seeks to minimise the impact of fluctuations in exchange rates on future cash flows and requires subsidiaries to hedge firm transaction exposures against their local currency at the time the exposure is identified. These exposures are hedged by the use of spot and forward exchange contracts. The Corp Group has overseas subsidiaries that earn profits or incur losses in their local currencies. It is not the Corp Group's policy to hedge the exposures arising from the translation of these overseas results into sterling. Gross borrowings at 30 September 2002 were L4,281 million (31 March 2002 L4,615 million, 2001 L3,677 million) and approximately 84 per cent. (31 March 2002 86 per cent., 2001 96 per cent.) of these were denominated in foreign currencies in order to form a hedge for the Corp Group's investments in currencies other than sterling. Of these, 61 per cent. (31 March 2002 62 per cent., 2001 59 per cent.) denominated in US dollars formed a hedge for the Corp Group's investment in the US, and 22 per cent. (31 March 2002 23 per cent., 2001 34 per cent.) denominated in Euros formed a hedge for the Corp Group's investments in the Eurozone. Under UK tax regulations, the Corp Group is exposed to tax on changes in the translations into sterling of its foreign currency borrowings. The Corp Group has in the past had outstanding derivative contracts with certain of its banks to eliminate the cash flow exposure resulting from these tax payments. No such contracts were outstanding in the six months ended 30 September 2002. The Corp Group has subsidiaries in most of the European countries which have converted to the Euro, and the major subsidiaries are located in Italy and Germany. Internal Corp Group reporting from companies in the Eurozone was switched to the Euro on 1 April 2001. The programme to ensure that all Eurozone subsidiaries convert in a timely and efficient manner has now been brought to a successful conclusion. COUNTERPARTY RISK All deposits are made with creditworthy and authorised counterparties. All forward contracts, swaps, and other derivative contracts, as described above, are similarly managed to ensure that the benefits of such financial hedging are subject to controlled counterparty risk. In the year ended 31 March 2001, Marconi Finance plc was established to provide finance to customers of the Corp Group. As at 31 March 2001, the Corp Group had committed L170 million of vendor finance to customers of which L135 million had been drawn down. As at 31 March 2002, the Group had vendor finance commitments of approximately L100 million ($142 million), of which L58 million ($82 million) had been drawn. In addition, the Corp Group provided a $90 million counter-indemnity to Phillips relating to the sale of Medical Systems. Approximately $42 million was paid out against this indemnity during the period to 31 March 2002. 397

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- As at 30 September 2002, the Corp Group had vendor finance commitments of approximately L68 million ($107 million) of which L54 million ($84 million) had been drawn. The Corp Group, like its competitors, continues to experience demand for financing from its customers. However, this demand has decreased significantly due to market conditions and the Corp Group's focus on its core base of incumbent carrier customers. When the Corp Group has supported customer financing requests, it has significantly limited its own risk by: i) leveraging funds from third party financiers having strategic interests aligned with the Corp Group, and ii) developing innovative commercial alternatives that do not involve long-term cash investments from Marconi. Through these actions, the Corp Group has satisfactorily accommodated most customer financing requests and will not require Corp Group cash resources to fund these activities in the foreseeable future. In addition, the Corp Group uses export credit agencies to assist in managing political and credit risks on major contracts and makes extensive use of export credit insurance in respect of small to medium-sized contracts. CONTRACT BONDING FACILITIES Some customers in the telecommunications market require that bank bonds or surety bonds (issued by insurance companies) are provided to guarantee performance of the supplier. The Corp Group had L221 million of Performance Bonds outstanding as at 30 September 2002 with both banks and insurance companies worldwide. The reduction from L500 million of bonds outstanding at 31 March 2002 was mainly the result of the disposal of Strategic Communications. Some of these bonds were covered by counter indemnities from Corp and others have counter indemnities from other Group companies. The Group's bonding is normally provided on an uncommitted basis. As a consequence of the Group's ongoing Restructuring all Performance Bonds currently have to be fully cash collateralised under a bonding facility agreed with some of the Corp Group's relationship banks. Since February 2002, Marconi Bonding Ltd (a special purpose vehicle used for this purpose) has procured the issue of approximately L80 million of performance bonding (on a fully cash collateralised basis) on behalf of other Corp Group companies. INSURANCE RISK MANAGEMENT The Corp Group manages centrally the purchase of global insurance policies in respect of major insurable risks, including property (material damage/business interruption), directors' and officers' and public and products liability. The Corp Group maintains the types of property and liability insurance which Corp regards as appropriate given the nature of the risks run in the course of its business, and for amounts which they consider adequate. When considering the appropriateness of insurance cover, Corp has made detailed assessments of insurable risks using both in-house professionals and the advice of insurance brokers. Corp has determined what they believe to be the appropriate level of cover having regard, among other things, to the Corp Group's loss record, the industry in which it operates, its risk tolerance level, the cost of cover relative to the risk, customer and legal requirements and any relevant and available information on the levels of cover typically purchased by other comparable companies which operate in the Corp Group's industry. The use of global policies and centrally appointed brokers allows the Corp Group to improve internal control and optimise the overall level of retained risk. Risk management and insurance spend are concentrated on those insurable risks which are considered potentially catastrophic to the Corp Group as a whole. The Corp Group continues to work with its insurers and advisers to improve its loss prevention and mitigation processes. Insurance market conditions are currently very challenging and premium rates have increased substantially. However, the Corp Group benefits from good relationships with its major insurers. PLC SHARE PRICE RISK The Corp Group has, in the past, issued share options to its employees under a number of different option plans, collectively known as the Employee Share Option Plans ("ESOPs"). Under these plans, options may be satisfied by way of a transfer of existing plc Shares acquired in the market by an employee trust or other vehicle, or, under some of the plans only, by an issue of new plc Shares. 398

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- From January 2000, in order to hedge part of the potential cost of the plans estimated at that time, the independent trustee of the MET, Bedell Cristin Trustees Limited ("BCT"), entered into swap contracts with three financial institutions (the ESOP Derivative Banks) to purchase a total of 40 million shares in the future at prices which were fixed at the date of the contract. At 30 September 2002, the purchase of 38.5 million shares under these contracts was outstanding. The Corp Group's maximum exposure under the contracts is L337 million, plus accrued finance charges. This amount had been accrued at 30 September 2002. Certain contracts require BCT to deposit cash collateral with the relevant ESOP Derivative Banks if the share price falls to certain levels stipulated in those contracts. Corp, at the request of plc, funds the provision of this collateral. At 30 September 2002, L214 million of collateral, the maximum amount of collateral payable under these contracts, had been paid. No further collateral will become due. Due to the substantial deterioration in plc's share price, only limited amounts of options with zero exercise price have been or are likely to be exercised. Following completion of the proposed Restructuring, existing plc options will no longer be exercisable. The remaining principal amount of L123 million under these contracts, together with accrued finance charges of L44 million at 30 September 2002 is the subject of claims brought against the Corp Group by the ESOP Derivative Banks. As part of the Corp Group's proposed Restructuring, it was agreed on 28 August 2002 that L170 million of the Corp Group's cash will be restricted and will be deposited in an escrow account pending settlement of potential liabilities in respect of these claims. Further information relating to the proposed post balance sheet settlement of these claims is set out in note 29.

Forward foreign currency contracts, interest rate swaps and other fair values have been calculated by discounting cash flows at prevailing interest rates. The book value of the equity swap reflects the existing provisions in respect of the share option scheme exposures to which the swap relates. The fair value includes accrued interest of L44 million (31 March 2002 L40 million, 2001 L23 million) which is fully provided for in the book value. The book and fair values are net of collateral paid of L214 million (31 March 2002 L214 million). This treatment reflects the change in circumstances due to share price movements in previous periods. (D) GAINS AND LOSSES ON HEDGES The Corp Group enters into forward foreign exchange contracts to eliminate the currency exposure arising on sales and purchases denominated in foreign currencies as soon as there is a firm contractual commitment. It also uses interest rate swaps to manage its interest rate profile. 405

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 1: CORP HISTORICAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- 29. POST BALANCE SHEET EVENTS On 7 February 2003 the plc Group announced that it had agreed in principle with Barclays Bank PLC, Salomon Brothers International Limited and UBS AG to settle potential claims under ESOP derivative arrangements. This settlement is conditional upon Corp's scheme of arrangement becoming effective. At this point, all claims against plc, Corp and its subsidiaries in respect of this matter will be waived and the total liabilities recorded within liability provisions and net debt of L169 million will be released for a consideration of L35 million. On 24 February 2003, Marconi announced that, following approval from the High Court in the United Kingdom, Corp had completed a return of capital from Ultramast Limited (a joint venture company set up in December 2000 with Railtrack Telecom Services Limited) and settled all outstanding litigation relating to it. As a result of the transaction, Marconi received net cash proceeds of approximately L41 million. 30. ULTIMATE CONTROLLING PARTY At 30 September 2002, Corp regarded plc, a company incorporated in Great Britain, as the ultimate parent company and the ultimate controlling party. plc is the parent company of the largest and smallest group of which Corp is a member and for which group financial statements are drawn up. Copies of their statutory financial statements are available from The Secretary, Marconi plc, New Century Park, PO Box 53, Coventry, Warwickshire CV3 1HJ. As Subsidiary undertakings of plc, Corp and its Subsidiary undertakings (90 per cent. or more of whose voting rights are controlled within the group), have taken advantage of the exemption in FRS 8 "Related party disclosures" from disclosing transactions with other members of the group headed by plc. 407

APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 2 CORP UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET The unaudited pro forma consolidated balance sheet set out below is based on the consolidated balance sheet of the Corp Group as at 30 September 2002 as set out in Appendix 1 of this document after making adjustments on the basis set out below and has been extracted without material amendment from the unaudited pro forma consolidated balance sheet set out in Part V of the Prospectus. The unaudited pro forma consolidated balance sheet has been prepared to illustrate the effect of the Corp Scheme and the Capital Reduction on the 30 September 2002 consolidated balance sheet as if the Corp Scheme and the Capital Reduction had been completed at that date. No adjustments have been made to reflect any transactions other than as described in this Appendix. In particular, no account has been taken of any subsequent transactions including, but not limited to, trading activities and restructuring costs, and the impact such transactions will have on the consolidated balance sheet. The pro forma information has been prepared for illustrative purposes only and, because of its nature, may not give a true picture of the consolidated balance sheet which would have been reported if it had been drawn up on the effective date of the transactions assumed. 408

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 NOTES TO THE ACCOUNTS 1 FUNDAMENTAL UNCERTAINTY IN RESPECT OF THE APPLICATION OF THE GOING CONCERN BASIS In the year to 31 March 2002, the plc Group met its day-to-day working capital requirements through syndicated banking facilities, certain bilateral bank facilities and its own cash resources. In addition, it has in issue Bonds with a face value of L1.8 billion, issued in order to finance acquisitions that occurred in the year to 31 March 2000. As at 31 March 2002, net debt stood at L2.9 billion. The plc Group's existing Syndicated Bank Facility expires on 25 March 2003. From October 2001, the plc Group has been in negotiations with these banks to provide facilities that would extend beyond this date. However, on 22 March 2002, the plc Group announced that in the light of the plc Group's revised view of the extended market downturn, it no longer believed that the refinancing proposal provided the plc Group with an appropriate capital structure. Accordingly, the plc Group decided that it was unable to enter into the proposed new Bank Facility. The bank coordinators indicated that the banks reserve all their rights under the existing bank facilities. In order to preserve the support of its Syndicate Banks, the plc Group announced that as a result of this decision, it had agreed to cancel the undrawn commitments under its syndicated facilities and to place on demand the drawn portion of the E4.5 billion facilities. The final maturity of the E4.5 billion Syndicated Bank Facility remains 25 March 2003. The plc Group has developed a revised business plan and is in discussion with its banks and bondholders in order to secure a capital structure that is appropriate to that business plan. plc has guaranteed certain derivative transactions related to the exercise of share options previously granted to employees of the plc Group, the borrowings of its subsidiary, Corp, under the syndicated bank facilities and the Bonds issued by Corp. The aggregate amount of these guarantees is disclosed in note 28 (a). If the guarantees are called, the extent to which plc ultimately bears the liabilities will depend on the extent to which the liabilities are satisfied by other plc Group companies. Given the current state of the negotiations with its bankers and Bondholders, plc has assessed whether it is probable that these guarantees will become actual liabilities and decided that the guarantees are currently not likely to crystallise. Consequently, these guarantees are not recorded in the plc balance sheet, but are disclosed as a contingent liability. In the light of the information currently available to them, plc believes that the plc Group's bankers and Bondholders will support it in achieving an appropriate capital structure. On this basis, plc considers it appropriate to prepare the accounts on a going concern basis. Should the plc Group's bankers and Bondholders not support the plc Group in achieving an appropriate capital structure, adjustments would be necessary to record additional liabilities and to write down assets to their recoverable amount. It is not practicable to quantify with reasonable accuracy these possible adjustments. 2 ACCOUNTING POLICIES The financial statements have been prepared in accordance with applicable accounting standards. The more important plc Group accounting policies are summarised below to facilitate the interpretation of the financial statements. ACCOUNTING CONVENTION The financial statements are prepared under the historical cost convention, as modified by the valuation of listed fixed asset investments. BASIS OF CONSOLIDATION The financial statements consolidate the accounts of plc and all of its subsidiary undertakings (plc Group companies or subsidiaries). 418

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 All accounts for plc Group companies are made up to 31 March. TURNOVER Turnover, excluding VAT, comprises sales to outside customers, and the plc Group's percentage interest in sales of joint ventures. The plc Group records transactions as sales when the delivery of products or performance of services takes place in accordance with the terms of sale. CURRENCY TRANSLATION Profits and losses of overseas subsidiaries, joint ventures and associates and cash flows of overseas subsidiaries are translated at the average rates of exchange during the year. Non-sterling net assets are translated at year-end rates of exchange. Key rates used are as follows: <Table> <Caption> Average rates Year-end rates -------------- -------------- 2002 2001 2002 2001 ----- ----- ----- ----- <S> <C> <C> <C> <C> US dollar 1.43 1.48 1.42 1.42 Italian lira 3,152 3,153 3,161 3,114 Euro 1.63 1.63 1.63 1.61 ===== ===== ===== ===== </Table> Reserves are adjusted to include the differences arising from the restatement to year-end rates of exchange of profits and losses and the translation of the net assets of overseas subsidiaries, joint ventures and associates from rates prevailing at the beginning of the year. All other exchange gains and losses are included in profit on ordinary activities before taxation. FINANCIAL INSTRUMENTS The plc Group uses financial instruments, including interest rate and currency swaps, solely for the purposes of raising finance for its operations and managing interest and currency risks associated with the plc Group's underlying business activities. There is no trading activity in financial instruments. FOREIGN EXCHANGE TRANSACTION EXPOSURES The plc Group hedges actual foreign exchange exposure as soon as there is a firm contractual commitment. Forward contracts are used to hedge the exposure. Amounts are included in the accounts at the forward exchange contract rate. If the contract ceases to be a hedge any subsequent gains or losses are recognised through the profit and loss account. BALANCE SHEET TRANSLATION EXPOSURES A large proportion of the plc Group's net assets are denominated in overseas currencies. Where appropriate, the plc Group hedges these balance sheet translation exposures by borrowing in relevant currencies and markets, and by the use of currency swaps. Currency swaps are used only as balance sheet hedging instruments, and the plc Group does not hedge the currency translation of its profit and loss account. Exchange gains or losses arising on the hedging borrowings and on the notional principal of currency swaps during their life and at termination or maturity, together with the tax thereon, are dealt with as a movement in reserves, where the conditions for offset are met. INTEREST RATE RISK EXPOSURE The plc Group hedges its exposure to movements in interest rates associated with its borrowing primarily by means of interest rate swaps and forward rate agreements. 419

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 TANGIBLE FIXED ASSETS Property, plant, machinery, fixtures, fittings, tools and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives. Freehold land does not bear depreciation where the original cost of purchase was separately identified. Tangible fixed assets are depreciated using the following rates: <Table> <S> <C> <C> Freehold buildings -- 2 per cent. to 4 per cent. per annum Leasehold property -- over the period of the lease or 50 years for long leases Plant and machinery -- 10 per cent. per annum on average Fixtures, fittings, tools and 10 per cent. per annum equipment -- </Table> LEASED ASSETS Assets held under finance lease are included in tangible fixed assets and the present values of lease commitments are included under creditors. Operating lease payments are charged to the profit and loss account as incurred. GOODWILL Purchased goodwill is capitalised and amortised on a straight-line basis over its estimated useful economic life. Each acquisition is separately evaluated for the purposes of determining the useful economic life, up to a maximum of 20 years. The useful economic lives are reviewed annually and revised if necessary. RESEARCH AND DEVELOPMENT Expenditure incurred in the year is charged against profit unless specifically chargeable to and receivable from customers under agreed contract terms. STOCKS AND CONTRACTS IN PROGRESS Stocks and contracts in progress are valued at the lower of cost, including appropriate overheads, and estimated net realisable value. Provisions are made for any losses incurred or expected to be incurred on uncompleted contracts. Profit on long-term contracts in progress is taken when a sale is recorded on part-delivery of products or part-performance of services, provided that the outcome of the contract can be assessed with reasonable certainty. Advance payments received from customers are shown as creditors unless there is a right of set-off against the value of work undertaken. Progress payments received are deducted from the value of the work carried out, any excess being included with payments received in advance. TAXATION Taxation on profit on ordinary activities is that which has been paid or becomes payable in respect of the profits for the year. Deferred taxation is provided in full on timing differences that result in an obligation at the balance sheet date to pay more tax, or a right to pay less tax, at a future date, at rates expected to apply when they crystallise based on current tax rates and law. Timing differences arise from the inclusion of items of income or expenditure in taxation computations in periods different from those in which they are included in the financial statements. Deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered. Deferred tax assets and liabilities are not discounted. INVESTMENTS Joint ventures comprise long-term investments where control is shared under a contractual arrangement. The sector analysis of turnover, profit and net assets includes the plc Group's share of the results and net assets of joint ventures. 420

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 Associates consist of long-term investments in which the plc Group holds a participating interest and over which it exercises significant influence. Investments in joint ventures and associates, other than Easynet Group Plc, are stated at the amount of the plc Group's share of net assets, including goodwill, at 31 March derived from audited or management accounts made up to that date. Easynet Group Plc's results are included for the period to 31 December. Profit before taxation includes the plc Group's share of joint ventures and associates. Other unlisted fixed asset investments and plc's investment in shares in plc Group companies are stated at cost less provision for impairment in value. Listed fixed asset investments are stated at market value. Current asset investments are stated at the lower of cost and net realisable value except dated listed securities which are stated at market value. Investments in plc's own shares, held within the GEC Employee Share Trust and the Marconi Employee Trust, are included on the plc Group balance sheet at cost, less provision for impairment. PENSIONS AND OTHER POST RETIREMENT BENEFITS The operating cost of providing pensions and other post retirement benefits, as calculated periodically by independent actuaries, is charged to the plc Group's operating profit or loss in the period that those benefits are earned by employees. The financial return expected on the pension schemes' assets is recognised in the period in which they arise as part of finance income and the effect of the unwinding of the discounted value of the schemes liabilities is treated as part of finance costs. The changes in value of the pension schemes' assets and liabilities are reported as actuarial gains or losses as they arise in the consolidated statement of total recognised gains and losses. The pension schemes' surpluses, to the extent they are considered recoverable, or deficits are recognised in full and presented in the balance sheet net of any related deferred tax. SHARE OPTIONS In accordance with UITF Abstract 17, "Employee share schemes", the costs of awarding shares under employee share plans are charged to the profit and loss account over the period to which the performance criteria relate. 3 CHANGES IN ACCOUNTING POLICY Since the last annual report, plc has changed three accounting policies. The format of the profit and loss account has been amended to improve the clarity and transparency of financial reporting. This is discussed further in note 5 to the Accounts. Financial Reporting Standard ("FRS") 19 "Deferred tax" has been adopted. This changes the basis of measurement of deferred tax assets and liabilities and the movements reported in the performance statements (profit and loss account and consolidated statement of total recognised gains and losses). The adoption of this accounting standard has had no effect on reported assets or liabilities nor the amounts recorded in the performance statements in respect of prior years. FRS 17 "Retirement benefits" has been adopted in full replacing Statement of Standard Accounting Practice ("SSAP") 24 "Accounting for pension costs" and Urgent Issues Task Force abstract ("UITF") 6 "Accounting for post-retirement benefits other than pensions". This changes the measurement basis of the pension surplus or 421

Separate components of goodwill are identified and amortised over the appropriate useful economic life. The remaining goodwill on the balance sheet will be amortised over an average period of approximately 7 years. Comparative figures have been restated to reflect the changes in the plc Group structure during the year to 31 March 2002. Currently, the net assets of Network equipment and Network services cannot be separately identified as the same assets are, generally, used to generate sales in each of these segments. The results of these segments are separately reportable. The plc Group share of joint ventures' profit, turnover and net assets are included under Capital. Sales by plc Group companies to joint ventures and associates amounted to L40 million (2001 L60 million). Purchases from joint ventures and associates amounted to L14 million (2001 L1 million). The contribution of subsidiaries acquired in the year ended 31 March 2002 was L12 million to turnover and L1 million to operating profit before goodwill amortisation and operating exceptional items. Assets and liabilities arising out of the Retirement Benefit Plan are treated as unallocated net liabilities. 423

For the year ended 31 March 2002 plc has altered the presentation of the plc Group profit and loss account (down to operating (loss)/profit) from a format 2 layout (which classifies expenditure by type) to a format 1 layout, (which classifies expenditure by function) both formats being defined by the Act. Accordingly the format 2 profit and loss disclosures have been restated for the year ended 31 March 2001. plc believes that format 1 profit and loss disclosures more accurately reflect the management of the business, improve users' understanding of the accounts, and aid comparison with the plc Group's competitors. 425

(6) The bonus paid to M J Donovan related to recruitment and retention arrangements established upon joining plc and before he became a Director. (7) Pension contributions include contributions by plc to all pension schemes. SHORT-TERM INCENTIVE BONUS In the year ended 31 March 2002, plc's Remuneration Committee approved the implementation short term incentive plan for Executive Directors with a maximum payment of 100 per cent. of salary although owing to subsequent events, no such plan was implemented and no short term incentive payments were made to Executive Directors in the year ended 31 March 2002. LONG-TERM INCENTIVES plc, has since its formation, operated two main discretionary plans, the 1999 Stock Option Plan and the Long-Term Incentive Plan. Options may be granted under the 1999 Stock Option Plan for a period of up to ten years from 30 November 1999. At the July 2001 plc Annual General Meeting, shareholders approved amendments to the plan rules giving the plc Remuneration Committee discretion to grant options which become exercisable over varying periods of time and which are subject to performance conditions appropriate to the markets in which plc operates. In previous years, plc's policy on the granting of options has been to make phased awards to key employees, based on business and personal performance, with the value of options granted normally ranging from 50 per cent. to 150 per cent. of basic salary per annum. Reductions in plc's share price meant both, that option holdings built up 432

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 over a number of years (with the minimum exercise value of any option granted under the plan having been L6.70) had lost any value as an incentive, and that grants based on these multiples of salary would result in an unacceptable level of dilution. In granting options to around 600 key executive, technical, and sales and marketing staff (including Executive Directors) in November 2001, the Remuneration Committee sought to balance an appropriate level of dilution with the need to provide a meaningful level of incentive. In exercising its discretion in respect of performance targets, the Remuneration Committee recognised the need for plc to achieve its short-term objectives in order to deliver longer-term performance. Of each option granted in November 2001, 50 per cent. is subject to the achievement of targets for the reduction in plc's net debt, and 50 per cent. subject to plc's Total Shareholder Return ("TSR") being better than that of the company at the fiftieth percentile for FTSE 100 companies. In order to provide a progressive incentive, options become exercisable, subject to the achievement of the performance conditions, over four years. Under the rules of the Long-Term Incentive Plan, Executive Directors can receive an annual award of notional shares up to a maximum value of 50 per cent. of base salary. Three years after the award, participants may be granted a nil cost option to acquire plc Shares, up to the number covered by the award, subject to a demanding performance condition. For Executive Directors this requires plc's TSR to be at or above that of the top 50 companies in the FTSE 100 share index, for other executives the requirement is for Total Business Return to be above 17 per cent. To the extent that the awards vest, the nil cost options are normally exercisable in three equal tranches on date of grant and one and two years thereafter. In respect of awards made in 1998, nil cost options to acquire plc Shares were granted to Executive Directors on 18 June 2001 as follows: M W J Parton -- 28,405; M J Donovan -- 6,036; S Hare -- 17,394. Owing to changed circumstances, no awards were made in the year ended 31 March 2002. In addition, plc also operates the Marconi UK Sharesave Plan and the Marconi Launch Share Plan (under which participants are eligible to receive 1,000 nil cost options in the event of plc's share price reaching L16.03 before November 2004) in which the Executive Directors and all eligible employees may participate. No award was made under the UK Sharesave Plan in 2001/02. The plc Group has previously operated a personal shareholding policy in order to assist further in aligning the interests of executives and shareholders. The policy requires Executive Directors to build up, over a period of time, a target shareholding of plc Shares with a market value equal to three times annual basic salary. The policy was not applied to the November 2001 option grant as it was not considered to be practical to do so, given plc's share price. RETIREMENT BENEFITS All Executive Directors are members of the plc Group's pension scheme, the GEC 1972 Plan (the "UK Plan"). Members contribute at the rate of 3 per cent. of salary subject to limits imposed by the Inland Revenue. plc contributions made during the year ended 31 March 2002 amounted to 6.6 per cent. of salary similarly restricted (2001 6.6 per cent.). plc has announced that, with effect from 6 April 2002, it will increase employers' contributions to 14.2 per cent. of salary. Basic salary is the only element of remuneration that is pensionable other than for S Hare whose bonuses are pensionable in accordance with the terms of the UK Plan. As with all employees who joined the Plan prior to the introduction of the statutory earnings cap on pensions introduced in April 1989, S Hare's bonus is pensionable. Further details about the plc Directors' benefits under the UK Plan are given below. Funded unapproved retirement benefit schemes ("FURBS") were operated during the year for five Executive Directors -- Lord Simpson, J C Mayo, M J Donovan, R I Meakin and M W J Parton. plc makes contributions to each of the FURBS on the advice of the actuary; such contributions are calculated to produce a capital sum targeted to provide benefits at the normal retirement age equivalent to a two-thirds pension. The targeted benefit takes into account the capital value of benefits arising from membership of the UK 1972 Plan and any relevant benefit in payment or otherwise arising from previous employment. Normal retirement age is 62 for Executive Directors. In the event of cessation of employment before normal retirement age, or at retirement age, each of the Directors is entitled to the amount held in the FURBS established for him. The Remuneration Committee has 433

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 reviewed the cost of such arrangements and has decided that it is not appropriate to plc's changed circumstances and will seek to change the basis of the FURBS it provides for Executive Directors and senior employees. In future, with the exception of the FURBS established for the benefit of M J Donovan, all FURBS will be based upon "defined contribution" rather than the present "defined benefit" arrangements. Prior to the year ended 31 March 2002, the contributions made to the plc Directors' FURBS were disclosed on a defined contribution basis. For the year ended 31 March 2002, owing to certain guarantees from plc which underpin the Directors' pension entitlements, plc believes that it is more appropriate to disclose the FURBS arrangements on a defined benefit basis in accordance with Actuarial Guidance Note GN11. This is consistent with the treatment of benefits accrued under the UK Plan. In addition to this disclosure, the plc Directors' remuneration table above also discloses within pension contributions, the contributions paid by plc in respect of these FURBS arrangements and all other pension arrangements, including the UK Plan.

The increase in accrued pension during the year excludes any increase for inflation. J C Mayo resigned as a Director of plc on 6 July 2001 and R I Meakin resigned from plc on 31 March 2002. During the year, plc made the following payments to the Trustee of the FURBS in respect of individual Directors: J C Mayo L633,000 (2001 L374,000); M J Donovan L63,966 (2001 L63,181); R I Meakin L290,000 (2001 L290,000); and M W J Parton L147,000 (2001 L147,000). No entry is shown for Lord Simpson as, in his case, his defined contribution entitlement due under the FURBS was completed in the year by the payment of L212,000 to the trustee of the FURBS. The contributions are determined each year based on actuarial advice to be sufficient to meet the obligations. Periodically the contributions are reviewed by the actuary.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 The pension entitlement shown above is that which would be paid annually at normal retirement age based on service to 31 March 2002. The increase in accrued pension during the year excludes any increase for inflation. The cost of pension benefits accrued during the year net of member's contributions has been calculated on the basis of actuarial advice in accordance with Actuarial Guidance Note GN11. The cost of pension benefits accrued during the year net of member's contributions is a measure of the capital cost of providing future pension payments and accordingly is a liability of the plc Group's pension arrangements and not a sum paid or due to the Directors of plc. The ability of plc to satisfy pension obligations for plc Directors subject to the earnings cap from plc's approved pension scheme, rather than unapproved schemes, is influenced by benefits payable from other approved pension schemes from their previous employment. In respect of M W J Parton, benefits accrued under approved plans from previous employment are lower than previously anticipated. Consequently, a higher proportion of his accrued pension benefit can be paid from the UK Plan, as opposed to FURBS arrangements and his accrued pension under the Plan has been increased as a result. His entitlement under the FURBS arrangements has been reduced by a corresponding amount. Members of the UK Plan have the option to make contributions to the Selected Benefit Scheme (an additional voluntary contribution scheme); neither the contributions nor the resulting benefits are included in the above table. DEATH IN SERVICE BENEFITS In the event of death in service, a lump sum of four times pensionable salary, plus additional benefits for a surviving spouse and/or children, inclusive of any death benefits arising from the UK Plan, will be held in trust for the benefit of dependants of each of M J Donovan, S Hare and M W J Parton. DIRECTORS' INTERESTS The plc Directors' interests as defined by the Act (which include trustee holdings and family interests incorporating holdings of minor children) in shares of plc and its subsidiaries are as follows: (A) ORDINARY SHARES <Table> <Caption> As at 31 March 2002 As at 1 April 2001 Beneficial (or later appointment) ------------------- ---------------------- <S> <C> <C> D C Bonham 156,000 6,000 Sir William Castell 10,000 10,000 The Rt Hon The Baroness Dunn 10,000 10,000 M J Donovan 169,591 67,601 S Hare 30,121 1,660 M W J Parton 128,122 28,860 Sir Alan Rudge 20,000 10,000 Hon Raymond G H Seitz 11,099 11,095 N J Stapleton 21,572 13,572 =================== ====================== </Table> None of the plc Directors held any non-beneficial interests in the shares of plc during the year ended 31 March 2002.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 A full actuarial valuation for the UK Plan was carried out as at 6 April 1999. A further actuarial investigation was performed for the UK Plan at 30 September 2001, and this was updated to 31 March 2002 by a qualified independent actuary. For the US plans, full valuations were carried out at dates between 1 January 2001 and 31 March 2002 and updated as applicable to 31 March 2002 by independent qualified actuaries. For the other European unfunded plans, valuations were carried out for accounting purposes at 31 March 2002. The contributions made to the plans in the accounting period totalled L36 million (2001 L46 million). For the unfunded pension plans and the post retirement medical plans, payments are made when the benefits are provided. From 6 April 2002, company contributions to the UK Plan were 14.2 per cent. of pensionable pay, reducing to 8.2 per cent. on 1 November 2002. Other than Italy, where approximately 7.4 per cent. of pensionable pay is accrued, the plc Group is not making significant contributions to its funded plans due to the high asset values already accumulated. The plc Group operates defined contribution schemes in addition to the defined benefit schemes listed. Contributions to these schemes amounted to L25 million (2001 L20 million). The major assumptions used by the actuaries to determine the liabilities on a FRS 17 basis for the significant defined benefit plans are set out below: <Table> <Caption> At 31 March 2002 At 31 March 2001 At 31 March 2000 ---------------------- ---------------------- ---------------------- Rest of Rest of Rest of UK the world UK the world UK the world (% pa) (% pa) (% pa) (% pa) (% pa) (% pa) ------ ------------- ------ ------------- ------ ------------- <S> <C> <C> <C> <C> <C> <C> AVERAGE ASSUMPTIONS USED: Rate of general increase in salaries 4.75% 4.23% 4.50% 4.92% 5.00% 4.63% Rate of increase in pensions in payment 2.75% 1.50% 2.50% 2.00% 3.00% 2.00% Rate of increase for deferred pensioners 2.75% N/A 2.50% N/A 3.00% N/A Rate of credited interest 5.50% N/A 5.75% N/A 6.00% N/A Discount rate applied to liabilities 6.00% 6.85% 6.00% 7.49% 6.00% 7.64% Inflation assumption 2.75% 2.25% 2.50% 2.44% 3.00% 2.44% Expected healthcare trend rates N/A 6% pre 65, N/A 7% pre 65, 9% N/A 7% pre 65, 7.5% post 65 post 65 10% post 65 reducing to reducing to reducing to 5% after 2005 5% after 2005 5% after 2005 ====== ============= ====== ============= ====== ============= </Table> The UK Plan provides benefits to members on the best of three bases. One of the bases is a money purchase underpin in which credited interest is applied to a percentage of members' contributions. The assumption has been determined as 0.5 per cent. less than the discount rate and reflects the UK Plan Trustee's practice in the long term of declaring credited interest broadly in line with fund returns. The discretionary level of credited interest has been treated as a constructive obligation. 455

For both years, actual investment returns in the UK and US plans fell well below expected investment returns resulting in substantial asset losses. The second largest element has been the gains and losses resulting from changes in assumptions underlying the present value of the plans' liabilities. These have resulted principally from the changes in assumptions used at each year end for the Plan. At 31 March 2001, the assumed rates of increase in inflation, salary increases and pension increases fell compared with those used at 31 March 2000. These changes resulted in a decrease in the present value of the liabilities at 31 March 2001 compared with those calculated at 31 March 2000, and this gave rise to a gain over the year. The assumptions were all increased at 31 March 2002, resulting in an increase in the 457

The plc Group is vigorously defending these cases, the estimated cost of which is disclosed above, and plc currently believes that the claims are unlikely to be settled for amounts resulting in material cash or other asset outflows. plc has guaranteed indebtedness and obligations of certain UK subsidiary undertakings including indebtedness related to Bond issues, which at 31 March 2002 amounted to L4,835 million (2001 L3,608 million). At 31 March 2002, the plc Group had provided third parties with Guarantees and performance Bonds, the exercise of which is considered to be remote.

Forward foreign currency contracts, interest rate swaps and other fair values have been calculated by discounting cash flows at prevailing interest rates. The book value of the equity swap reflects the existing provisions in respect of the share option scheme exposures to which the swap relates. The fair value includes accrued interest of L40 million which is fully provided for in the book value. The book and fair values are net of collateral paid of L214 million. This treatment reflects the change in circumstances due to share price movements in the year. D GAINS AND LOSSES ON HEDGES The plc Group enters into forward foreign exchange contracts to eliminate the currency exposure arising on sales and purchases denominated in foreign currencies as soon as there is a firm contractual commitment. It also uses interest rate swaps to manage its interest rate profile.

Aggregate gains of L25 million from previous years were recognised in the profit and loss account for the year. In addition to the amounts disclosed above, cumulative aggregate gains of L27 million in respect of terminated interest rate swaps were carried forward in the balance sheet as at 31 March 2002 pending their recognition in the profit and loss account (31 March 2001 gains of L40 million). Of these carried forward gains, approximately L11 million is expected to be recognised in the profit and loss account in the next accounting period (31 March 2001 gains of L12 million). Aggregate related gains of L12 million from previous years were recognised in the profit and loss account in the period (31 March 2001 Lnil). 30 POST BALANCE SHEET EVENTS On 3 May 2002, the plc Group placed L850 million of cash in an arrangement with its bankers that restricted the use of that cash to certain limited purposes until 27 May 2002. After this date, cash can be utilised with five business days' notice. 467

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 NOTES 1 FUNDAMENTAL UNCERTAINTY IN RESPECT OF THE APPLICATION OF THE GOING CONCERN BASIS Corp owes approximately L2.1 billion under a syndicated credit facility (the "Bank Facility") which was due for repayment on 25 March 2003. Borrowings under the facility are repayable on demand and no further funds may be drawn under its terms. The plc Group also has in issue Bonds with a face value of approximately L1.7 billion. plc guarantees Corp's debt obligations under the Bonds and the Bank Facility. As at 30 September 2002, net debt of the plc Group stood at approximately L2.8 billion. On 29 August 2002, plc announced that non-binding indicative Heads of Terms, which set out the principles for the financial Restructuring of Corp and plc, had been concluded with the co-ordination committee of Syndicate Banks and an informal ad hoc committee of Bondholders. On 16 December 2002, plc announced that modifications to the non-binding indicative Heads of Terms had been concluded. The non-binding indicative Heads of Terms envisage that the creditors of Corp and plc, other than certain excluded creditors, will be subject to schemes of arrangement ("Schemes") under which creditor claims will be compromised in consideration for cash, New Shares and New Notes. As part of the Restructuring Corp will become the listed parent for the Group and, following completion of the plc Scheme, it is currently intended that plc will be liquidated or dissolved. The financial Restructuring will leave existing plc Shareholders with 0.5 per cent. of the equity in Corp. On 17 March 2003, documentation for the proposed Schemes was filed with the High Court of England and Wales, initiating the final steps towards implementation of the Restructuring. The non-binding indicative Heads of Terms envisage a new capital structure for the Group that is appropriate to the latest business plan developed by the plc Group. The implementation of this capital structure involves, among other things, the payment of L340 million of cash (in addition to L95 million accrued interest on Corp's financial debt, paid in September and October 2002), the issue of New Shares and the issue of New Notes with a face value, using 30 September 2002 exchange rates, of approximately L758 million by Corp to Scheme Creditors through the operation of the Schemes. As part of the arrangements to implement the Restructuring, the majority of the plc Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the plc Group's Syndicate Banks and Bondholders (including the Bond trustees, but excluding Ancrane, a Subsidiary of plc which holds Bonds) and also in favour of one of the Group's ESOP Derivative Banks (who committed to support the proposed Restructuring within the required period). At 30 September 2002, the balance of this secured cash amounted to L735 million. The plc Group is dependent on amounts available to it from the secured accounts in order to meet its short-term liquidity needs. Prior to the release of interim security and so long as an enforcement event does not occur, monthly releases from the secured accounts will be allowed in accordance with an agreed cash flow schedule, subject to specified maximum amounts. This agreed cash flow schedule is consistent with the plc Group's expectations as to its liquidity needs for the period to the end of June 2003. When the Heads of Terms were announced on 29 August 2002, the Group indicated that the Restructuring was scheduled to be completed by 31 January 2003 (the "Effective Date"). This date was extended to 15 March 2003 in December 2002. As a result of the complexity of the Restructuring the Effective Date of the Schemes is now expected to be on or around 19 May 2003. The change to the timing of the Restructuring introduces risks associated with certain financial debt falling due in March 2003. In particular, as noted above, the Bank Facility was due for repayment on 25 March 2003 and interest payments were due on the Yankee Bonds on 17 March 2003 and are due on the Eurobonds on 31 March 2003. Failure to repay the Bank Facility has given rise to direct rights on the part of individual Syndicate Banks to bring actions for recovery of the debt owing to them and will, in addition, after the expiry of a five business day grace period, result in a cross default under the Bonds. In common with the Group's approach to other Scheme claims, pending the outcome of the Schemes, the Group does not intend to make payment in respect of such obligations, in full or in part. 473

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 The fact of the aforementioned payments falling due represents a risk to the Restructuring, due to consequential legal action which Syndicate Banks or Bondholders who are not supportive of the Restructuring process could take against Corp or plc. However, plc is of the view that, given the timing associated with any such legal action as well as the likely attitude of the English and New York Courts to a creditor seeking to frustrate the Restructuring (which is intended to be for the benefit of all Scheme creditors), these risks should be manageable. The interim security is subject to various enforcement events, some of which are tied to the prospects of successfully completing the Restructuring in accordance with the non-binding indicative Heads of Terms (and within the agreed timetable, which is currently 30 June 2003). The occurrence of an enforcement event entitles the requisite majority of creditors to block withdrawals from the secured accounts and/or enforce the interim security. The proposed Restructuring of plc is dependent on approval of the Corp and plc Schemes of arrangement. Approval of these Schemes will be dependent on, amongst other things, securing the necessary level of support of the Syndicate Banks, Bondholders and other creditors whose claims will be compromised, in the relevant creditors' meetings to be held as part of the Scheme process, as well as the approval of the English Court and the granting of a permanent injunction order by the US Bankruptcy Court. Letters of current intention to support the Restructuring and to vote for the Corp and plc Schemes were obtained from the joint lead co-ordinators of the Syndicate Banks and from each of the members of the Bondholder committee in December 2002. Neither plc nor Corp has received any notice of any changes to this intention. In the light of the information currently available to them, plc believes the Group's Syndicate Banks, Bondholders and other creditors will support the Restructuring and that all the conditions for the Restructuring will be satisfied. On this basis, plc considers it appropriate to prepare the accounts on the going concern basis. Should the plc Group's Syndicate Banks, Bondholders and other creditors cease to support the plc Group before the completion of the Restructuring, or should all of the conditions for the Restructuring not be met, there would be no realistic alternative for plc and Corp but to commence insolvency proceedings and the going concern basis of preparation would no longer be applicable; adjustments would be necessary to record additional liabilities and to write down assets to their recoverable amount. It is not practicable to quantify these possible adjustments. 2 ACCOUNTING POLICIES The non-statutory financial statements have been prepared in accordance with accounting standards applicable in the UK. The more important plc Group accounting policies are summarised below to facilitate the interpretation of the financial statements. ACCOUNTING CONVENTION The non-statutory financial statements are prepared under the historical cost convention, as modified by the valuation of listed current and fixed asset investments. BASIS OF CONSOLIDATION The non-statutory financial statements consolidate the accounts of plc and all of its Subsidiary undertakings (plc Group companies or Subsidiaries). All inter-company balances and transactions have been eliminated upon consolidation. All plc Group companies' accounts have been prepared for the six months ended 30 September 2002. TURNOVER Turnover, excluding VAT, comprises sales to outside customers, and the plc Group's percentage interest in sales by their joint ventures. The plc Group records transactions as sales when the delivery of products or performance 474

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 of services takes place in accordance with the terms of sale. Turnover on long term contracts is calculated as a proportion of the total contract value based on the ratio of costs incurred to date compared with the total expected costs for that contract. CURRENCY TRANSLATION Transactions denominated in foreign currencies are translated into the functional currency at the rates ruling at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are retranslated at the rates ruling at that date. These translation differences are dealt with in the profit and loss account with the exception of certain gains and losses arising under hedging transactions as described below. Profits and losses of overseas subsidiaries, joint ventures and associates and cash flows of overseas subsidiaries are translated at the average rates of exchange during the period. Non-sterling net assets are translated at period end rates of exchange. Key rates used are as follows: <Table> <Caption> Average rates Period-end rates ------------------------ ------------------------ 30 September 31 March 30 September 31 March 2002 2002 2002 2002 ------------ -------- ------------ -------- <S> <C> <C> <C> <C> US dollar 1.5204 1.4324 1.5726 1.4240 Italian lira n/a 3,152 n/a 3,161 Euro 1.5813 1.6283 1.5913 1.6323 ============ ======== ============ ======== </Table> The differences arising from the restatement of profits and losses and the retranslation of the opening net assets/(liabilities) to period end rates are taken to reserves. ACQUISITIONS AND DISPOSALS On the acquisition of a business, including an interest in an associated undertaking, fair values are attributed to the plc Group's share of separable net assets. Where the cost of acquisition exceeds the fair values attributable to such net assets, the difference is treated as purchased goodwill and capitalised in the balance sheet in the year of acquisition. The profit or loss on the disposal or closure of a previously acquired business includes the attributable amount of any purchased goodwill relating to that business not previously charged to the profit and loss account. The results and cashflows relating to a business are included in the consolidated profit and loss account and the consolidated cashflow statement from the date of acquisition or up to the date of disposal. FINANCIAL INSTRUMENTS The plc Group uses financial instruments, including interest rate swaps, currency swaps and other derivatives, solely for the purposes of raising finance for its operations and managing interest and currency risk associated with the plc Group's underlying business activities. There is no trading activity in financial instruments. FORWARD FOREIGN EXCHANGE CONTRACTS Forward foreign exchange contracts generally exhibit a high correlation to the hedged items and are designated and considered effective as hedges of the underlying assets, liabilities and firm commitments. Gains and losses on forward foreign exchange contracts which are designated as hedges of assets, liabilities and firm commitments of the Group are recognised in the profit and loss account or as adjustments to carrying amounts when the hedged transactions occurs. 475

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 HEDGES OF THE NET INVESTMENT IN OVERSEAS SUBSIDIARIES The plc Group's policy has been to finance its activities in the same currencies as those used for its foreign investments in order to hedge foreign currency exposure of net investments in foreign operations. This policy is implemented either by financing in the related currency or using derivatives, such as currency swaps, which provide a synthetic effect of a foreign currency loan, thereby reducing the exchange risk. Exchange gains or losses arising on the hedging borrowings and on the notional principal of currency swaps during their life and at termination or maturity, together with the tax thereon, are dealt with as a movement in reserves, to the extent they offset losses or gains on the hedged investment. In respect of hedges of net investments, the plc Group enters into tax equalisation swaps, the gains and losses of which are recognised through the statement of total recognised gains and losses (in accordance with the underlying transaction and the tax thereon) with any forward premium or discount recognised over the life of the contract in the profit and loss account. EQUITY FORWARD CONTRACTS The plc Group has established three trusts for the purchase of shares and share-related instruments for the benefit of employees -- the Marconi Employee Trust ("MET"), the GEC Employee Share Trust and the GEC Special Purpose Trust. These trusts are consolidated in the financial statements of the plc Group. The independent trustee of the MET, Bedell Cristin Trustees Limited ("BCT") has entered into contracts (the "Equity Forward Contracts") to hedge the potential cost of the plc Group's share plans. On or before maturity of the Equity Forward Contracts, the MET may either take delivery of plc Shares at the contracted purchase price (including accrued interest) or may cash settle the contracts for a net amount based on the difference between the plc share price and this contract purchase price (including accrued interest). The obligation to settle the contracts including accrued interest is classified as a provision within the plc Group's balance sheet. This liability is calculated by taking the shares under contract and applying the difference between plc's share price and the contract purchase price per share, adjusted for brokerage costs, on a contract-by-contract basis. No cash is exchanged until the maturity of the contract (or earlier upon either option exercises by employees or cash settlement of the contracts at the MET's option) unless collateral is required. Where the MET has provided collateral this has been offset against the provision in the balance sheet. Interest costs on the equity notional are calculated at LIBOR plus a margin less dividends, if any, and are accrued on a monthly basis, with a debit to interest and a credit to provisions. INTEREST RATE RISK EXPOSURE The plc Group hedges its exposure to movements in interest rates associated with its borrowing primarily by means of interest rate swaps and forward rate agreements. Payments and receipts under interest rate swap agreements specifically designated for hedging purposes are recorded in the profit and loss account on an accruals basis. Gains and losses arising on termination of hedging instruments where the underlying exposure remains are recognised in the profit and loss account over the remaining life of the underlying exposure. TANGIBLE FIXED ASSETS Property, plant, machinery, fixtures, fittings, tools and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives from the time they are brought into use. Freehold land does not bear depreciation where the original cost of purchase was separately identified. Provision is made for any impairment. 476

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 Tangible fixed assets are depreciated using the following rates: <Table> <S> <C> Freehold buildings -- 2 per cent. to 4 per cent. per annum Leasehold property -- over the period of the lease or 50 years for long leases Plant and machinery -- 10 per cent. per annum on average Fixtures, fittings, tools and equipment -- 10 per cent. per annum </Table> LEASED ASSETS Assets held under finance lease and other similar contracts, which confer rights and obligations similar to those attached to owned asset, are capitalised as tangible fixed assets and are depreciated over the shorter of the lease terms and their useful lives. The capital elements of future lease obligations are recorded as liabilities, while the interest elements are charged to the profit and loss account over the period of the leases to produce a constant rate of charge on the balance of the capital repayments outstanding. Hire purchase transactions are dealt with similarly except that assets are depreciated over their useful lives. Rentals under operating leases are charged on a straight-line basis over the lease term, even if the payments are not made on such a basis. GOODWILL Purchased goodwill is capitalised and amortised on a straight-line basis over its estimated useful economic life. Each acquisition is separately evaluated for the purposes of determining the useful economic life, up to a maximum of 20 years. The useful economic lives are reviewed annually and revised if necessary. Provision is made for any impairment. RESEARCH AND DEVELOPMENT Expenditure incurred in the period is charged against profit unless specifically chargeable to and receivable from customers under agreed contract terms. STOCK Stock is stated at the lower of cost and net realisable value. Provision is made for obsolete, slow-moving or defective items where appropriate. CONTRACTS IN PROGRESS Profit on long-term contracts in progress is taken when a sale is recorded on part-delivery of products or part-performance of services, provided that the outcome of the contract can be assessed with reasonable certainty. Amounts recoverable on long-term contracts, which are included in debtors, are stated at the net sales value of the work done less amounts received as progress payments on account. Excess progress payments are included in creditors as payments received in advance. Cumulative costs incurred net of amounts transferred to cost of sales, less provision for contingencies and anticipated future losses on contracts, are included as long-term contract balances in stock. WARRANTIES Provisions for estimated expenses related to product warranties are made at the time products are sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims. 477

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 TAXATION Taxation on profit on ordinary activities is that which has been paid or becomes payable in respect of the profits for the year. Deferred taxation is provided in full on timing differences that result in an obligation at the balance sheet date to pay more tax, or a right to pay less tax, at a future date, at rates expected to apply when they crystallise based on current tax rates and law. Timing differences arise from the inclusion of items of income or expenditure in taxation computations in periods different from those in which they are included in the financial statements. Deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered. Deferred tax assets and liabilities are not discounted. INVESTMENTS Joint ventures comprise long-term investments where control is shared under a contractual arrangement. The sector analysis of turnover, profit and net assets includes the plc Group's share of the results and net assets of joint ventures. Associates consist of long-term investments in which the plc Group holds a participating interest and over which it exercises significant influence. Investments in joint ventures and associates are stated at the amount of the plc Group's share of net assets including goodwill at 30 September 2002 derived from audited or management accounts made up to that date, other than Easynet Group Plc whose results are included for the six months to 30 June 2002. Loss before taxation includes the plc Group's share of joint ventures and associates. Other unlisted fixed asset investments are stated at cost less provision for impairment in value. Listed fixed asset investments are stated at market value. Current asset investments are stated at the lower of cost and net realisable value except dated listed securities which are stated at market value. Investments in plc's Shares, held within the GEC Employee Share Trust and the Marconi Employee Trust, are included on the plc Group balance sheet at cost, less provision for impairment. PENSIONS AND OTHER POST RETIREMENT BENEFITS The operating cost of providing pensions and other post retirement benefits, as calculated periodically by independent actuaries, is charged to the plc Group's operating profit or loss in the period that those benefits are earned by employees. The financial return expected on the pension schemes' assets is recognised in the period in which they arise as part of finance income and the effect of the unwinding of the discounted value of the schemes liabilities is treated as part of finance costs. The changes in value of the pension schemes' assets and liabilities are reported as actuarial gains or losses as they arise in the consolidated statement of total recognised gains and losses. The pension schemes' surpluses, to the extent they are considered recoverable, or deficits are recognised in full and presented in the balance sheet net of any related deferred tax. SHARE OPTIONS The costs of awarding shares under employee share plans are charged to the profit and loss account over the period to which the performance criteria relate. Where share options granted lapse, any associated costs that were treated as cost of acquisition are credited to either goodwill, or to the profit and loss account if there is no remaining goodwill. FINANCE COSTS Finance costs of debt are recognised in the profit and loss account over the term of such instruments at a constant rate on the carrying amount. DEBT Debt is initially stated at the amount of the net proceeds after deduction of issue costs. The carrying amount is increased by the finance cost in respect of the accounting period and reduced by payments made in the period. 478

The plc Group's Core businesses are the provision of optical networks, broadband routing and switching and broadband access technologies and associated installation, maintenance and other value-added services. Their customer base includes telecommunications companies, providers of Internet services for their public networks, and to certain large corporations, government departments and agencies, utilities and educational institutions for their private networks. Core activities are divided into Network equipment, Network services and Other. Capital comprises the businesses the plc Group manages for value and ultimately for disposal. Goodwill arising on acquisitions is amortised over a period not exceeding 20 years. Separate components of goodwill are identified and amortised over the appropriate useful economic life. The remaining goodwill on the balance sheet will be amortised over an average period of approximately 7 years. Comparative figures have been restated to reflect the changes in the plc Group structure during the period to 30 September 2002. The net assets of Network equipment and Network services cannot be separately identified as the same assets are, generally, used to generate sales in each of these segments. The results of these segments are separately reportable. 479

Sales by plc Group companies to joint ventures and associates amounted to L16 million (31 March 2002 L40 million). Purchases from joint ventures and associates amounted to Lnil (31 March 2002 L14 million). Assets and liabilities arising out of the Retirement Benefit Plan are treated as unallocated net liabilities. It is not practical to disclose goodwill amortisation on a segmental basis as any allocation would be arbitrary.

Further information on disposals is provided in note 26 (b). 5 EXCEPTIONAL ITEMS These charges have been analysed as follows: A OPERATING EXCEPTIONAL ITEMS <Table> <Caption> Six months to Year to 30 September 31 March 2002 2002 L million L million ------------- --------- <S> <C> <C> Stock write-downs and related costs -- (672) Restructuring costs (24) (158) ------------- -------- Included in cost of sales (24) (830) ------------- -------- Impairment of goodwill & tangible fixed assets (31) (3,831) Restructuring and reorganisation costs (171) (324) Systems implementation costs 7 (75) Releases/(charges) in respect of doubtful debts 8 (150) ------------- -------- Included in administrative expenses (187) (4,380) ------------- -------- plc Group operating exceptional items (211) (5,210) Share of joint ventures' operating exceptional items (31) (6) plc Group share of associates' operating exceptional items (18) (173) ------------- -------- Total operating exceptional items (260) (5,389) ============= ======== </Table> (i) In the year ended 31 March 2002 the stock write-downs and related costs charged to cost of sales in the year included L581 million for obsolescence and slow-moving provisions against a number of product lines, predominantly optical networking products, and L91 million in respect of supplier commitments. 482

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 (ii) In the six months ended 30 September 2002 L24 million was charged to restructuring costs. This relates mostly to additional payments to Jabil Circuit Inc. arising in the six month period. In the year ended 31 March 2002 restructuring costs classified within cost of sales includes a charge of L127 million representing additional costs incurred as a consequence of the decision to outsource certain manufacturing operations to Jabil Circuit Inc. Under the terms of the agreement, payments of L77 million were made during the year, L19 million provided against stocks and L31 million is expected to be paid in the future. The remaining charge of L31 million in the year ended 31 March 2002 relates to onerous contracts representing certain liabilities to which the plc Group is committed as a result of the operational restructuring. This includes liabilities, relating to equipment leasing contracts and supply contracts under which it has been agreed to purchase minimum volumes of goods and services which will offer no economic value to the business as a result of its reduced size. (iii) In light of declining industry and economic trends on its current and expected future operations, the plc Group reassessed the carrying values of goodwill and tangible fixed assets. In the six months ended 30 September 2002 tangible fixed assets were impaired by L31 million (31 March 2002 L154 million). In the year ended 31 March 2002, as a consequence of the more uncertain sales outlook and more conservative future assessment of future growth prospects of acquired businesses the plc Group recorded an exceptional charge of L3,677 million to write down goodwill. The goodwill impairment related primarily to FORE Systems, RELTEC Corporation, Metapath Software International ("MSI"), Mariposa Technology, ipsaris (formerly Fibreway), Systems Management Specialists ("SMS") and Albany Partnership ("APT"). (iv) As part of the plc Group's cost reduction actions, a charge of L171 million (31 March 2002 L324 million) was recorded during the six months to 30 September 2002 associated with employee severance, site rationalisation costs and other restructuring costs. The site rationalisation costs reflect the charges associated with closing and consolidating various sites around the world as part of the business restructuring and the other restructuring costs represent various other costs associated with the restructuring program. (v) During the year ended 31 March 2002 the plc Group planned to implement a new global IT system. In light of the revised trading outlook and the continued focus on cost reduction, the implementation was terminated. The L75 million charge represents L43 million of capitalised external consultancy costs associated with the implementation, L24 million of hardware and software costs expensed, and L8 million of other associated costs of the project. During the six months ended 30 September 2002, the plc Group was able to revise its previous estimate of the overall costs leading to the release of L7 million from the amounts accrued in the year to 31 March 2002. (vi) In light of the declining market and economic trends the plc Group was experiencing, an exceptional provision against bad and doubtful debts of L150 million was charged during the year ended 31 March 2002. Of this amount, L8 million was paid by the plc Group's debtors in the six months to 30 September 2002. 483

This comprised a L5 million loss on disposal of discontinued operations, a L9 million net loss on disposal of fixed assets and investments in continuing operations and a L3 million loss relating to the plc Group's share of associates' non-operating exceptional charges. In discontinued operations, the loss on disposal of Strategic Communications (L41 million) was partially offset by the release of provisions relating to Medical Systems and other previously completed disposals. Of the L9 million loss on disposal of fixed assets and investments in continuing operations, L40 million related to the write-down of some of the plc Group's investments in line with its accounting policy whereby listed investments are marked to their market value at the end of each reporting period and unlisted investments are held at the lower of cost and net realisable value. This was partially offset by a L28 million curtailment gain associated with retirement benefits arising mainly from the disposal of the plc Group's 50 per cent. share in General Domestic Appliances, L12 million gain on property disposals and a net L9 million charge relating to current and prior period disposals and business closures and other provision movements. In the year ended 31 March 2002 a gain of L358 million was made mainly relating to the disposal of the systems businesses (Medical, Commerce and Data Systems). Share options For the year ended 31 March 2002, the release of provisions related to demerger share options which arose due to the significant reduction in plc's share price and comprised two elements. L247 million related to a provision created in respect of the Marconi Launch Share Plan. A further L44 million was released that related to provisions in respect of other option schemes created at the time of the MES Transaction. 485

Included in the unrecognised deferred tax asset as at 30 September 2002 of L798 million are amounts that may be forfeited or restricted as a consequence of the planned Restructuring of the plc Group due to the requirements of tax legislation in various jurisdictions. It is not possible at this stage to quantify the amount of unrecognised deferred tax assets that may be forfeited. 9 EQUITY MINORITY INTERESTS Equity minority interests represent the share of the profits less losses on ordinary activities attributable to the interests of equity shareholders in subsidiaries which are not wholly owned by the plc Group. 10 EQUITY DIVIDENDS plc has decided not to propose any dividends for the year ending 31 March 2003. No dividends were declared during the year to 31 March 2002. 11 LOSS PER SHARE Basic and diluted loss per share are calculated by reference to a weighted average of 2,792.6 million ordinary shares (31 March 2002 2,789.6 million ordinary shares) in issue during the period. The effect of share options is anti-dilutive for each period presented and has therefore been excluded from the calculation of diluted weighted average number of shares.

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 12 DIRECTORS A POLICY AND OBJECTIVES OF THE REMUNERATION COMMITTEE The role of the Remuneration Committee has been to determine, on behalf of the Board of plc, the broad framework for executive remuneration including the remuneration of Executive Directors. The underlying principles adopted by the Committee have been: - to ensure that executive remuneration policy and practices support business strategy and are cost effective; - to provide remuneration packages which are competitive within plc's operating environment, enabling plc to attract, retain and motivate senior executives with high quality and appropriate skills; and - to operate short and long term incentive plans, as part of total remuneration, which reward the delivery of results aligned with shareholders interests while limiting earnings where there is under- performance. The exceptional nature of the challenges faced by plc during the period, including the extremely difficult trading conditions requiring continuing major reductions in the cost base and the Restructuring process, have all had major implications for the remuneration of executives under these principles. In supporting the Restructuring of plc, the objectives of the remuneration committee have been: - to ensure that the management team is fairly and equitably rewarded in accordance with the changed circumstances of plc; and - to provide management and employees with appropriate incentives focused on the priorities of cash generation and successful completion, of the Restructuring.

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 subsequent events, no such plan was implemented and no short-term incentive payments were made to Executive Directors in the year ended 31 March 2002. In the six months ended 30 September 2002, Executive Directors participated in an exceptional incentive plan with payment related to successful completion of the Restructuring of plc Group. The maximum payment under this plan is 150 per cent. of salary. Executive Directors also participated in a quarterly incentive plan with payments due for the achievement of targets for the generation of total cash. Payment relating to the six months ending 30 September 2002 has not been made under this plan and it is anticipated that Executive Directors will agree to waive entitlement to these payments on entering into new employment agreements with Corp. Long-term incentive schemes Aggregate emoluments detailed above do not include any amounts in respect of long-term incentive schemes. plc operates a number of schemes as described below. At a meeting held on 3 November 1999, shareholders approved the introduction of a number of share plans following the reconstruction of GEC and the Listing of plc on 30 November 1999. Two main discretionary plans were approved -- the Marconi 1999 Stock Option Plan and the Marconi Long Term Incentive Plan with the Executive Directors eligible to participate in both plans. In addition, shareholders approved the introduction of the Marconi UK Sharesave Plan and the Marconi Launch Share Plan in which Executive Directors and all eligible employees may participate. Full details of options granted to Executive Directors under these plans are set out below. In summary, options may be granted under the Marconi 1999 Stock Option Plan for a period of up to ten years from 30 November 1999. Options granted under the plan prior to 18 July 2001 become exercisable three years from the date of grant, provided the performance condition has been met, that is the percentage increase in plc's earnings per share must be equal to or greater than the percentage increase in the Retail Prices Index plus 3 per cent. per annum. Thus the shortest period over which the performance target can be satisfied is three financial years from the date of grant; if the target is not satisfied after this period, it can be retested over the four financial years from the date of grant, and so on. At the July 2001 plc Annual General Meeting, shareholders approved amendments to the plan rules giving the plc Remuneration Committee discretion to grant options which become exercisable over varying periods of time and which are subject to performance conditions appropriate to the markets in which plc operates. In previous years, plc's policy on the granting of options has been to make phased awards to key employees, based on business and personal performance, with the value of options granted normally ranging from 50 per cent. to 150 per cent. of basic salary per annum. Reductions in plc's share price meant that option holdings built up over a number of years (with the minimum exercise value of any option granted under the Plan having been L6.70) had lost any value as an incentive, and that grants based on these multiples of salary would result in an unacceptable level of dilution. In granting options to around 600 key executive, technical, and sales and marketing staff (including Executive Directors) in November 2001, the Remuneration Committee sought to balance an appropriate level of dilution with the need to provide a meaningful level of incentive. In exercising its discretion in respect of performance targets, the Remuneration Committee recognised the need for plc to achieve its near term objectives in order to deliver longer term performance. Of each option granted in November 2001, 50 per cent. is subject to the achievement of targets for the reduction in plc's net debt, and 50 per cent. subject to plc's Total Shareholder Return ("TSR") compared to that of FTSE 100 companies. None of this 50 per cent. becomes exercisable if plc's TSR is the same as that of the company at the 50th percentile, all becomes exercisable at the 75th percentile, with progressive increases between these points. In order to provide a progressive incentive, options become exercisable, subject to the achievement of the performance conditions, over four years. Under the Long Term Incentive Plan, each year Executive Directors can receive an award of up to a maximum of 50 per cent. of basic salary, subject to satisfaction of demanding corporate performance over the three years from the date of award. After three years from the date of award, provided plc's TSR is in the top 50 of the FTSE 100 492

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 index, participants may be granted a nil cost option to acquire plc Shares. To the extent that the awards vest, the nil cost options will normally be exercisable in three tranches, one third immediately upon vesting, one third on the first anniversary and one third on the second anniversary of the date of grant. On 30 November 1999, Executive Directors participated in the plan for the first time; their nil cost options under the plan vest in two annual tranches from July 2002; the shorter performance period and the accelerated vesting of the tranches reflect the fact that the grant of these awards was delayed by reason of the transaction with British Aerospace plc (now known as BAE SYSTEMS plc). The employment of these Executive Directors was subsequently terminated and no options have been granted. Current Executive Directors first received awards in April 1998 and details of conditional awards are contained in the table below. The conditional awards of notional shares made to Executive Directors are as follows: <Table> <Caption> Notional Award Notional shares at lapses shares at 31 March 30 June 30 September 2002 2002 2002 Number Number Number --------- ------- ------------ <S> <C> <C> <C> M J Donovan 57,919 (33,201) 24,718 M W J Parton 61,897 (35,414) 26,483 S Hare 32,490 (16,600) 15,890 ======== ======= ============ </Table> The plc Group has previously operated a personal shareholding policy in order to assist in further aligning the interests of executives and shareholders. The policy requires Executive Directors to build up, over a period of time, a target shareholding of plc Shares with a market value equal to three times annual basic salary. The policy was not applied to the November 2001 option grant as it was not considered to be practical to do so, given plc's share price. C PLC DIRECTORS' INTERESTS The plc Directors' interests as defined by the Act (which include trustee holdings and family interests incorporating holdings of minor children) in plc and its Subsidiaries are as follows: (i) Ordinary shares <Table> <Caption> As at As at 31 March 30 September 2002 2002 Beneficial Beneficial ---------- ------------ <S> <C> <C> Sir William Castell 10,000 10,000 The Rt Hon The Baroness Dunn 10,000 n/a M J Donovan 169,591 169,670 M W J Parton 128,122 128,122 Sir Alan Rudge 20,000 20,000 Hon Raymond G H Seitz 11,099 11,099 N J Stapleton 21,572 21,572 D C Bonham 156,000 156,000 S Hare 30,121 30,121 A L Thomas n/a -- ========== ============ </Table> --------------- Notes 1.

There have been no other changes in the interests of plc Directors between 30 September 2002 and 27 March 2003. 3. On the date of incorporation, 17 September 1999, and on 4 October 1999, the date on which certain of the plc Directors were appointed, none of the plc Directors at that time held any interest in the share capital of plc. 4. A L Thomas was appointed to the Board of plc on 20 May 2002 and he resigned on 14 March 2003. On 11 April 2002, The Rt Hon The Baroness Dunn resigned from the Board of plc. On 8 October 2002, Sir William Castell and N J Stapleton resigned from the Board of plc. On 14 November 2002, S Hare resigned from the Board of Marconi plc and C C Holden was appointed to the Board of plc.

The options set out above relate to those granted under the Manager's 1984 Share Option Scheme, the 1997 Executive Share Option Scheme, the Marconi 1999 Stock Option Plan, the Phantom Option Schemes, the Long Term Incentive Plan, the Employee 1992 Savings-Related Share Option Scheme, the Marconi Launch Share Plan and the Marconi UK Sharesave Plan. 2. The mid-market price of a plc share as at 30 September 2002 was 1.45 pence with a range during the period of 1.27 pence to 12.55 pence. 3. All options have exercise prices that exceed the market price of a plc share as at 30 September 2002, other than nil cost options granted under the Marconi Launch Share Plan (1,000 shares at nil cost) and the Marconi Long Term Incentive Plan. D RETIREMENT BENEFITS All Executive Directors are members of (or are entitled to be members of) the plc Group's approved pension scheme, the GEC 1972 Plan (the "UK Plan"). Members contribute at the rate of 3 per cent. of salary subject to limits imposed by the Inland Revenue. plc contributions made during the six months ended 30 September 2002 amounted to 14.2 per cent. of salary, similarly restricted (year ended 31 March 2002 6.6 per cent.). The increase in contributions resulted from an interim actuarial valuation of the UK Plan, which was undertaken as at 30 September 2001, following the sale of part of the business of plc. The results of this valuation revealed there was a deficit in the UK Plan at that time of L137 million and, on the advice of the actuary, the rate of employers' contributions was increased. FURBS have been established for two of the current Directors -- M J Donovan and M W J Parton. In the case of M W J Parton, gross contributions to the FURBS are paid at the rate of 35 per cent. of basic salary, with 21 per cent. being paid into the FURBS and the remaining 14 per cent. direct to M W J Parton. The accumulated balance in the FURBS, including investment returns, is payable to M W J Parton on retirement. M J Donovan's FURBS is funded on a defined benefit basis, with projected benefits (including under other plans) of two-thirds of his final pensionable salary. The pension will be made up from M J Donovan's benefits under the UK Plan, the FURBS, two BAE pension plans and any other retained benefits he may have. The current contribution rate (to be reviewed in May 2003) is 39 per cent. of his base salary (although while M J Donovan is posted to the US, the rate is 46 per cent., owing to local tax legislation). FURBS contributions for M J Donovan are paid into the 494

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 FURBS and to M J Donovan himself in the ratio of 60:40 (or as necessary under US tax law). This is because the contributions are taxable benefits, so the payment to M J Donovan is to offset the higher income tax charge for which he is liable. The FURBS documents oblige Corp to fund an unapproved life assurance scheme, which is to provide a lump sum on death in service or four times basic salary and a widow's pension of four-ninths of final pensionable salary. A contribution of L240,000 was paid into M J Donovan's FURBS in 2002 to make good a deficit shown by its last actuarial valuation. Normal retirement age is 62 for Executive Directors. If M J Donovan retires on or after his fifty-fifth birthday, there will be no actuarial reduction in the value of his benefits. In the event of cessation of employment before normal retirement age, or at retirement age, each of the plc Directors is entitled to the amount held in the FURBS established for him. FURBS were also established for former Directors -- Lord Simpson, R I Meakin and J C Mayo. In the case of Lord Simpson, the final contribution to his FURBS was made in October 2001 and no further contributions are due from plc. In the case of R I Meakin, a final contribution was paid by plc on 14 January 2003. In the case of J C Mayo, contributions to fully fund his FURBS were paid on 5 July 2002. There is an ongoing obligation to review the funding level each year in the FURBS for current employees, which may result in additional contributions being required. The remuneration committee has reviewed the cost of FURBS arrangements for the Executive Directors and has decided that it is not appropriate to plc's changed circumstances. Consequently, plc has sought to change the basis of the FURBS it provides for the current Executive Directors. With effect from 1 April 2002, the FURBS for Mr Parton was changed to a defined contribution basis as described below. For the six months ended 30 September 2002 the only current plc Director who has a defined benefit FURBS was M J Donovan. His FURBS is disclosed in accordance with the Actuarial Guidance Note GN11. This is consistent with the treatment of benefits accrued under the Plan. In accordance with the requirements of the Listing Rules, the disclosures required for each period are set out below. The figures for pensions shown below are the contributions paid by the plc Group in respect of each plc Director. In addition to this disclosure, the plc Directors' remuneration table above also discloses within pension contributions, the contributions paid by plc in respect of these FURBS arrangements and all other pension arrangements including the Plan. The pension benefits earned by the Directors of plc under the Plan are: As at 30 September 2002 <Table> <Caption> Cost of pension Accumulated benefits accrued total accrued Length of Increase in during the period pension at pensionable accrued pension net of member's 30 September service during the period contributions 2002 Name of plc Director Years L000 L000 L000 ------------------------------- ----------- ----------------- ----------------- ------------- <S> <C> <C> <C> <C> M J Donovan 4 1 -- 6 S Hare 13 2 7 71 M W J Parton 11 1 2 25 =========== ================= ================= ============ </Table> --------------- Notes 1. The pension entitlement shown is that which would be paid annually at the normal retirement age based on service to the end of the period. 2. The increase in accrued pension during the period excludes any increase for inflation. 3. The cost of pension benefits accrued during the period net of member's contributions has been calculated on the basis of actuarial advice in accordance with Actuarial Guidance Note GN11. The cost of pension benefits accrued during the period net of member's contributions is a measure of the capital cost of providing future pension payments and accordingly is a liability of the plc Group's pension arrangements and not a sum paid or due to the Directors of plc. 495

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 4. The ability of plc to satisfy pension obligations for plc Directors subject to the earnings cap from plc's approved pension scheme, rather than unapproved schemes, is influenced by benefits payable from other approved pension schemes from their previous employment. In respect of M W J Parton, benefits accrued under approved plans from previous employment were lower than anticipated prior to the period ended 31 March 2002. Consequently, a higher proportion of his accrued pension benefit can be paid from the UK Plan, as opposed to FURBS arrangements. Consequently, his accrued pension under the UK Plan is increased in the period ended 31 March 2002 and, as a result, his entitlement under the FURBS arrangements for that period is reduced by a corresponding amount. With effect from 1 April 2002, M W J Parton's FURBS entitlements are provided on a defined contribution basis, with benefits accrued under approved plans payable in addition. 5. Members of the UK Plan have the option to make additional voluntary contributions; neither any additional voluntary contributions nor the resulting benefits are included in the above table. 6. In the event of death in service, a lump sum of four times pensionable salary, plus additional benefits for a surviving spouse and/or children, inclusive of any death benefits arising from the UK Plan, will be held in trust for the benefit of the dependants of serving Directors who are members of the UK Plan. The pension benefits earned by the Directors of plc under the FURBS arrangements are: As at 30 September 2002 <Table> <Caption> Cost of pension Accumulated benefits accrued total accrued Length of Increase in during the period pension at pensionable accrued pension net of member's 30 September service during the period contributions 2002 Name of plc Director Years L000 L000 L000 ------------------------------- ----------- ----------------- ----------------- ------------- <S> <C> <C> <C> <C> M J Donovan 4 4 16 68 =========== ================= ================= ============ </Table> The following payments have been made to the Trustee of the FURBS: <Table> <Caption> Six months Year ended ended 31 March 30 September 2002 2002 Name of plc Director L000 L000 -------------------- ---------- ------------ <S> <C> <C> M J Donovan 64 288 J C Mayo 633 257 R I Meakin 290 290 M W J Parton 147 55 Lord Simpson 212 -- ========== ============ </Table> --------------- Notes 1. The pension entitlement shown above is that which would be paid annually at normal retirement age based on service to the end of the period. 2. The increase in accrued pension during the period excludes any increase for inflation. 3. Lord Simpson's defined contribution entitlement due under the FURBS was completed in the year ended 31 March 2002 by the payment of L212,000 to the trustees of the FURBS. Lord Simpson resigned as a Director of plc on 4 September 2001. J C Mayo resigned as a Director of plc on 6 July 2001 and a payment of L257,000 was paid to his FURBS in respect of pensionable service for the period to 5 July 2002. R I Meakin resigned as a Director of plc on 1 March 2002. A contribution of L568,000 became due immediately. L290,000 was paid in the period up to 30 September 2002 with the final contribution of L278,000 to be paid to his FURBS by plc on or before 14 January 2003 with a further non-pensionable allowance of L185,000 being paid directly to R I Meakin in final settlement of his FURBS entitlements. 4. The contributions are determined each period based on actuarial advice to be sufficient to meet the obligations. Periodically the contributions are reviewed by the actuary. An actuarial valuation of M J Donovan's FURBS, disclosed a deficit of L240,000. A contribution of L240,000 was therefore paid by plc into the FURBS in addition to regular contributions with a further non-pensionable allowance of L228,284 being paid directly to M J Donovan. 496

Following the continued difficult market conditions, plc announced expectations of a delay in market recovery beyond the end of 2003; significant changes to the plc Group forecasts have been made, and a further review has been undertaken at 30 September 2002. The average discount rate applied to the future cash flows is 15 per cent. and is based upon a weighted average cost of capital percentage. The results of the review indicated that no further impairment charge in respect of goodwill was necessary for the 6 months to 30 September 2002.

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 Marconi Mobile Holdings S.p.A., the holding company for the plc Group's Strategic Communications business, was disposed of on 2 August 2002 and the Marconi Applied Technologies Group was disposed of on 12 July 2002. 27 POST RETIREMENT BENEFITS The plc Group operates defined benefit pension plans in the UK, US and Europe, and post-retirement benefit plans in the US. The most significant plan is the GEC 1972 Plan (the "UK Plan") in the UK. A full actuarial valuation for the UK Plan was carried out as at 5 April 2002 and a valuation for accounting purposes was carried out as at 30 September 2002 by independent qualified actuaries. As a result of the separation of Marconi Electronic Systems ("MES") in November 1999, the MES employees ceased to participate in the UK Plan and, on 6 April 2000, were transferred to a new BAE SYSTEMS plc pension scheme (the BAE SYSTEMS plc 2000 Pension Plan -- the "BAE Plan") providing identical benefits to the UK Plan. A share of the UK Plan's assets were transferred to the corresponding new BAE Plan, proportional to the share of the total UK Plan's liabilities as at 6 April 2000 that were attributable to the MES members, based on actuarial calculations performed as at 6 April 2000. For the US Plans, full valuations were carried out at dates between 1 January 2001 and 31 March 2002 and updated as applicable to 30 September 2002 by independent qualified actuaries. For the European unfunded plans, valuations were carried out for accounting purposes at 30 September 2002 by independent qualified actuaries. The contributions made to the plans in the accounting period totalled L19 million (31 March 2002 L36 million). For the unfunded pension plans and the post retirement medical plans, payments are made when the benefits are provided. Since April 2002, company contributions to the UK Plan were 14.2 per cent. of pensionable pay, reducing to 8.2 per cent. on 1 November 2002. Other than Italy, where approximately 7.4 per cent. of pensionable pay is accrued, the plc Group is not making significant contributions to its overseas funded plans due to the high surpluses in the schemes at the time of the last funding valuations. The plc Group operates defined contribution schemes in addition to the defined benefit schemes listed. Contributions to these schemes amounted to L1 million (31 March 2002 L25 million). The major assumptions used by the actuaries to determine the liabilities on a FRS17 basis for the significant defined benefit plans are set out below: <Table> <Caption> At 30 September 2002 At 31 March 2002 ------------------------------- ------------------------------- Rest of the Rest of the UK World UK World Average assumptions used: (per cent. pa) (per cent. pa) (per cent. pa) (per cent. pa) ------------------------- -------------- -------------- -------------- -------------- <S> <C> <C> <C> <C> Rate of general increase in salaries 4.50 3.0-5.1 4.75 4.23 Rate of increase in pensions in payment 2.50 1.5-2.5 2.75 1.50 Rate of increase for deferred pensioners 2.50 n/a 2.75 n/a Rate of credited interest 4.00 n/a 5.50 n/a Discount rate applied to liabilities 5.25 5.5-6.5 6.00 6.85 Inflation assumption 2.50 1.5-2.5 2.75 2.25 7 pre 65, 6 pre 65, 7 post 65 7.5 post 65 Expected healthcare trend rates n/a reducing to n/a reducing to 5 after 2005 5 after 2005 ============== ============= ============== ============= </Table> 513

For all the periods actual investment returns in the UK and US Plans fell well below expected investment returns resulting in substantial asset losses. The second largest element has been gains and losses resulting from changes in assumptions underlying the present value of the Plans' liabilities. These have resulted principally from the changes in assumptions used at each period end for the Plan. These assumptions were all increased at 30 September 2002, resulting in an increase in the present value of liabilities at 30 September 2002 compared with those calculated at 31 March 2002, and this gave rise to a loss over the period.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 29 FINANCIAL INSTRUMENTS A TREASURY POLICIES AND ORGANISATION The plc Group's treasury activities are coordinated by its treasury function which operates in accordance with policies and procedures approved by plc. It does not operate as a profit centre. Treasury advises operational management on treasury matters and undertakes all derivative transactions except certain forward exchange contracts relating to the hedging of foreign currency transaction exposures arising in the operating businesses which have in the past been managed by those operating units as described below. All treasury related transactions undertaken by the plc Group's operating businesses are required to be in accordance with guidelines laid down by the plc Group's central treasury function and comply with the group risk management policies. Short-term debtors and creditors have been excluded from all disclosures within note 29 except the currency profile. FINANCIAL INSTRUMENTS The plc Group uses financial instruments, including derivatives (principally interest rate swaps, cancellable interest rate swaps, currency swaps and forward foreign currency contracts) to manage interest rate and currency risk exposures. It is the plc Group's policy that there is no trading in financial instruments, and all financial instruments are used for the purpose of financing or hedging identified exposures of the plc Group. The main risks faced by the plc Group in the financial markets are liquidity risk, interest rate risk, foreign currency risk, counterparty risk and share price risk. The plc Board reviews and agrees policies for managing each of these, which are summarised below. LIQUIDITY RISK The plc Group has funded its activities through cash generated from its operational activities, the proceeds of disposals, bank borrowings and the debt capital markets. The plc Group's gross borrowings as at 30 September 2002 were L3,917 million (at 31 March 2002 L4,268 million) and reflected the repayment of local borrowings in Italy as a result of the disposal of the Strategic Communications business and a substantial reduction in the sterling value of the US$ denominated debt due to foreign exchange movements. At 30 September 2002, the plc Group's cash and liquid resources totalled L1,071 million (31 March 2002 L1,374 million), of which L152 million (31 March 2002 L278 million) was denominated in sterling, L508 million (31 March 2002 L738 million) in US dollars, L358 million (31 March 2002 L239 million) in Euro and the balance of L53 million (31 March 2002 L119 million) in other currencies. At 30 September 2002, the plc Group had E3.6 billion (31 March 2002 E3.6 billion) of bank facilities. At 30 September 2002 and 31 March 2002 all facilities were payable on demand. As previously disclosed, the majority of the plc Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the plc Group's Syndicate Banks and Bondholders (including the Bond trustees) and also in favour of one of the ESOP Derivative Banks (who committed to support the Restructuring within the required period). The secured accounts were created at the end of April 2002 in accordance with the previously disclosed lock box arrangements entered into in favour of the Syndicate Banks and Bondholders. The interim security arrangements contemplated by the Heads of Terms were implemented on 13 September 2002, the balance of this secured cash amounted to L735 million at 30 September 2002. The plc Group is dependent on amounts available to it from the secured amounts in order to meet its short-term liquidity needs. Prior to the release of interim security and so long as an enforcement event does not occur, monthly releases from the secured accounts will be allowed in accordance with an agreed cash flow schedule, subject to specified maximum amounts. This agreed cash flow schedule takes account of the plc Group's anticipated cash inflows and outflows, and is consistent with the plc Group's expectations as to its liquidity needs for the relevant period. 519

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 Further details on the interim security arrangements and the plc Group's liquidity risk are set out in note 1. INTEREST RATE RISK It has in the past been plc Group policy to maintain at least 50 per cent. of debt at fixed rates of interest. The term structure of interest rates was managed in observance of this policy using derivative financial instruments such as interest rate swaps. However, due to the Restructuring process described above, this has been superseded by the requirement to manage immediate liquidity including the cancellation of all outstanding derivatives positions. Consequently, during the first half of the financial year, out-of-the-money interest rate swap arrangements with fair value L54 million were converted to new loan agreements, and cash proceeds of L8 million were received from unwinding in-the-money interest rate swap arrangements. At 30 September 2002, 48 per cent. (31 March 2002 53 per cent) of the plc Group's interest-bearing borrowings were at fixed rates after taking account of interest rate swaps. Of this total, 29 per cent. (31 March 2002 43 per cent) were at fixed dollar rates of interest and 19 per cent. (31 March 2002 10 per cent) were at fixed Euro rates of interest. In the six months ended 30 September 2002, the average interest rate received on cash and liquid investments was approximately 2.4 per cent. per annum. The largest proportion of investments was in US$ deposits. The plc Group held an average of $856 million in US$ deposits, earning an average interest rate of 1.75 per cent. per annum. Due to the proportion of fixed rate debt, the plc Group's interest charge has limited exposure to interest rate movements. Consequently an increase in market interest rates of one percentage point would have increased loss before taxation in the six months ended 30 September 2002 by approximately L5 million (year ended 31 March 2002 L12 million). FOREIGN EXCHANGE RISK The plc Group is exposed to movements in foreign exchange rates against sterling for both trading transactions and the translation of net assets and the profit and loss accounts of overseas subsidiaries. The main trading currencies of the plc Group are the US dollar, sterling and the Euro. The foreign currency management policy of the plc Group seeks to minimise the impact of fluctuations in exchange rates on future cash flows and requires subsidiaries to hedge firm transaction exposures against their local currency at the time the exposure is identified. These exposures are hedged by the use of spot and forward exchange contracts. The plc Group has overseas subsidiaries that earn profits or incur losses in their local currencies. It is not the plc Group's policy to hedge the exposures arising from the translation of these overseas results into sterling. However, approximately 83 per cent. of gross borrowings were denominated in foreign currencies in order to form a hedge for investments in currencies other than sterling. Of these, 63 per cent, denominated in US dollars, formed a hedge for the plc Group's investment in the United States, and 20 per cent, denominated in Euro, formed a hedge for the plc Group's investment in the Euro zone. Under UK tax regulations, the plc Group is exposed to tax on changes in the translations into sterling of its foreign currency borrowings. The plc Group has in the past had outstanding derivative contracts with certain of its banks to eliminate the cash flow exposure resulting from these tax payments. No such contracts were outstanding in the six months ended 30 September 2002. The plc Group has subsidiaries in most of the European countries which have converted to the Euro, and the major subsidiaries are located in Italy and Germany. Internal Group reporting from companies in the Eurozone was switched to the Euro on 1 April 2001. The programme to ensure that all Eurozone subsidiaries convert in a timely and efficient manner has now been brought to a successful conclusion. 520

All forward contracts, swaps, and other derivative contracts, as described above, are similarly managed to ensure that the benefits of such financial hedging are subject to controlled counterparty risk. As at 30 September 2002, the plc Group had vendor finance commitments of approximately L68 million ($107 million) of which L54 million ($84 million) had been drawn. The plc Group, like its competitors, continues to experience demand for financing from its customers. However, this demand has decreased significantly due to market conditions and the plc Group's focus on its core base of incumbent carrier customers. When the plc Group has supported customer financing requests, it has significantly limited its own risk by: i) leveraging funds from third party financiers' having strategic interests aligned with the plc Group, and ii) developing innovative commercial alternatives that do not involve long-term cash investments from the plc Group. Through these actions, the plc Group has satisfactorily accommodated most customer financing requests and will not require plc Group cash resources to fund these activities in the foreseeable future. In addition the plc Group uses export credit agencies to assist in managing political and credit risks on major contracts and makes extensive use of export credit insurance in respect of small to medium-sized contracts. CONTRACT BONDING FACILITIES Some customers in the telecommunications market require that bank bonds or surety bonds (issued by insurance companies) are provided to guarantee performance of the supplier. plc Group companies had L221 million of Performance Bonds outstanding as at 30 September 2002 with both banks and insurance companies worldwide. The reduction from L500 million of Performance Bonds outstanding at 31 March 2002 was mainly as a result of the disposal of Strategic Communications. Some of these facilities are covered by counter-indemnities from Corp and others have individual indemnities from other plc Group companies. The plc Group's Performance Bonding is normally provided on an uncommitted basis. As a consequence of the plc Group's ongoing financial restructuring, all new Performance Bonds currently have to be cash collateralised. Since February 2002, Marconi Performance Bonding Limited (a special purpose vehicle used for this purpose) has procured the issue of approximately L80 million of performance bonding (on a fully cash collateralised basis) on behalf of other plc Group companies. INSURANCE RISK MANAGEMENT The plc Group has managed centrally the purchase of global insurance policies in respect of major insurable risks, including property (material damage/business interruption), directors' and officers and public and products liability. The Group has maintained the types of property and liability insurance which plc regard as appropriate given the nature of the risks run in the course of its business, and for amounts which they consider adequate. 521

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 3: PLC FINANCIAL INFORMATION TO 30 SEPTEMBER 2002 -------------------------------------------------------------------------------- SIX MONTHS ENDED 30 SEPTEMBER 2002 When considering the appropriateness of insurance cover, plc has made detailed assessments of insurable risks using both in-house professionals and the advice of insurance brokers. plc has determined what it believes to be the appropriate level of cover having regard, among other things, to the Group's loss record, the industry in which it operates, its risk tolerance level, the cost of cover relative to the risk, customer and legal requirements and any relevant and available information on the levels of cover typically purchased by other comparable companies which operate in the Group's industry. The use of global policies and centrally appointed brokers allows the plc Group to improve internal control and optimise the overall level of retained risk. Risk management and insurance spend are concentrated on those insurable risks which are considered potentially catastrophic to the plc Group as a whole. The plc Group continues to work with its insurers and advisers to improve its loss prevention and mitigation processes. Insurance market conditions are currently very challenging and premium rates have increased substantially. However, the plc Group benefits from good relationships with its major insurers and from some long-term deals. PLC SHARE PRICE RISK The plc Group has, in the past, issued share options to it employees under a number of different option plans, collectively known as the Employee Share Option Plans ("ESOPs"). Under these plans, options may be satisfied by way of a transfer of existing plc Shares acquired in the market by an employee trust or other vehicle, or, under some of the plans only, by an issue of new plc Shares. From January 2000, in order to hedge part of the potential cost of the plans estimated at that time, the independent trustee of the Marconi Employee Trust ("MET"), Bedell Cristin Trustees Limited ("BCT"), entered into swap contracts with three financial institutions (the "ESOP Derivative Banks") to purchase a total of 40 million shares in the future at prices which were fixed at the date of the contract. At 30 September 2002, the purchase of 38.5 million shares under these contracts remain outstanding. The plc Group's maximum exposure under the contracts was approximately L337 million, plus accrued finance charges as at 30 September 2002. Certain contracts require BCT to deposit cash collateral with the relevant ESOP Derivative Bank if the share price falls to certain levels stipulated in those contracts. Corp, at the request of plc, funds the provision of this collateral. At 30 September 2002, L214 million of collateral, the maximum amount of collateral payable under these contracts, had been paid. No further collateral will become due. Due to the substantial deterioration in the plc Group's share price, only limited amounts of options with zero exercise price have been or are likely to be exercised. Following completion of the proposed Restructuring, existing plc options will no longer be exercisable. The remaining principal amount of approximately L123 million under these contracts, together with accrued finance charges of L44 million at 30 September 2002 is the subject of claims brought against the plc Group by the ESOP Derivative Banks. As part of the plc Group's proposed Restructuring, it was agreed on 28 August 2002 that L170 million of the plc Group's cash will be restricted and will be deposited in an escrow account pending settlement of potential liabilities in respect of these claims. Further information relating to the proposed post balance sheet settlement of these claims is set out in note 30. 522

Forward foreign currency contracts, interest rate swaps and other fair values have been calculated by discounting cash flows at prevailing interest rates. The book value of the equity swap reflects the existing provisions in respect of the share option scheme exposures to which the swap relates. The fair value includes accrued interest of L44 million (31 March 2002 L40 million) which is fully provided for in the book value. The book and fair values are net of collateral paid of L214 million (31 March 2002 L214 million). E GAINS AND LOSSES ON HEDGES The plc Group enters into forward foreign exchange contracts to eliminate the currency exposure arising on sales and purchases denominated in foreign currencies as soon as there is a firm contractual commitment. It also uses interest rate swaps to manage its interest rate profile. An analysis of these unrecognised gains and losses is as follows: <Table> <Caption> Total net gains/ Gains Losses (losses) L million L million L million --------- --------- --------- <S> <C> <C> <C> Unrecognised gains and losses on hedges at 1 April 2002 23 (24) (1) Gains and losses arising in previous years that were recognised in the period 23 (19) 4 --------- --------- --------- Gains and losses arising before 1 April 2002 that were not recognised in the period -- (5) (5) Gains and losses arising in the period to 30 September 2002 that were not recognised in the period -- (20) (20) --------- --------- --------- Unrecognised gains and losses on hedges at 30 September 2002 -- (25) (25) ========= ========= ========= Of which: --------- --------- --------- Gains and losses expected to be recognised in the period to 31 March 2003 -- (25) (25) ========= ========= ========= </Table> 527

In addition to the amounts disclosed above, cumulative aggregate gains of L30 million and losses of L56 million in respect of terminated interest rate swaps were carried forward in the balance sheet as at 30 September 2002 pending their recognition in the profit and loss account (31 March 2002 gains of L27 million). Of these carried forward gains and losses, gains of L7 million and losses of L4 million are expected to be recognised in the profit and loss account in the next accounting period (31 March 2002 gains of L11 million). Aggregate related gains of L6 million from previous years were recognised in the profit and loss account in the period (year ended 31 March 2002 L12 million). 30 POST BALANCE SHEET EVENTS On 7 February 2003 the plc Group announced that it had agreed in principle with Barclays Bank PLC, Salomon Brothers International Limited and UBS AG to settle potential claims under ESOP derivative arrangements. This settlement is conditional upon Corp's scheme of arrangement becoming effective. At this point, all claims against plc, Corp and its subsidiaries in respect of this matter will be waived and the total liabilities recorded within liability provisions and net debt of L169 million will be released for a consideration of L35 million. On 24 February 2003, Marconi announced that, following approval from the High Court in the United Kingdom, Corp had completed a return of capital from Ultramast Limited (a joint venture company set up in December 2000 with Railtrack Telecom Services Limited) and settled all outstanding litigation relating to it. As a result of the transaction, Marconi received net cash proceeds of approximately L41 million. 528

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- PART A PLC QUARTERLY REPORT TO 31 DECEMBER 2002 MARCONI PLC OPERATIONAL AND FINANCIAL REVIEW FOR THE THREE MONTHS ENDED 31 DECEMBER 2002 FORWARD-LOOKING STATEMENTS This Operational and Financial Review contains certain statements that are or may be forward-looking. These statements typically contain words such as "intends", "expects", "anticipates", "estimates" and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances which may occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to future revenues being lower than expected; increasing competitive pressures within the industry; general economic conditions or conditions affecting the relevant industries, both domestically and internationally, being less favourable than expected. These factors and other factors that could affect these forward-looking statements are described in the plc's Form 20-F report and Form 6-K reports filed with the US Securities and Exchange Commission. Corp and plc disclaim any obligation to publicly update or revise these forward-looking statements, whether to reflect new information or future events or circumstances or otherwise. OVERVIEW Overall conditions in the telecommunications market remained tough during the third quarter. Trading levels in EMEA in the third quarter remained stable despite the continuing difficult market environment. plc is now beginning to observe some slowing of business in the Middle East as a result of the current political environment. The North American market continues to be characterised by further tightening of capital expenditure by a number of large telecom operators, particularly towards the end of their financial years in December. In Central and Latin America (CALA), the market was relatively stable during the quarter although capital expenditure amongst major operators in the region remained at a low level. In Asia-Pacific (APAC), while the market remains buoyant in Australia, conditions in the Chinese market are more difficult as a result of delays in capital expenditure due to the re-organisation of key customers, delays to the roll-out of certain network build projects and increased pricing pressure on new business. Despite the difficult market environment, the Group continued to make significant progress during the quarter towards its targets to improve operating performance in the Core business. In particular compared to the previous quarter, further cost savings achieved during the period led to an approximate 0.5 percentage point increase in Core gross margin (before exceptional items) to 22.1 per cent and an approximate L85 million reduction in Core operating cost run-rate (before goodwill amortisation and exceptional items) to L550 million at 31 December 2002. Headcount reductions are a major driver of the Group's cost reduction initiatives. At 31 December 2002, the Group employed just over 16,000 employees in its Core business, down from just over 19,000 at 30 September 2002. The Group's improved operating performance combined with further progress in all areas of working capital management, led to a significant improvement in adjusted operating cash flow, with the Group recording an operating cash inflow (before exceptional items) of L72 million during the quarter. Non-operating and exceptional cash outflows (excluding tax) of L88 million relating mainly to the Group's ongoing operational and financial restructuring processes and interest paid were partially offset by a net L45 million tax repayment received during the period. In total during the third quarter, the Group generated cash of L29 million before use of liquid resources and financing. The Group was awarded a number of important business wins during the period. These included the first European sale of the Group's BXR-48000 multi-service switch-router to a large financial institution and the first sale of the Group's recently launched Softswitch to Jersey Telecom. In addition, since the beginning of calendar year 2003, the Group has announced two major new business wins from Telecom Italia: a Euro 80 million 530

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- (approximately L50 million) frame contract for the supply of the Access Hub and a new 2-year frame contract estimated at approximately Euro 15 million (approximately L10 million) to build an optical backbone network architecture based on the Group's recently launched next generation digital cross-connect, the MSH2K. BOARD During the third quarter and more recently, plc has announced a number of changes to the Boards of Directors as a result of which the Boards of Corp and plc now comprise: <Table> <S> <C> <C> Executive Directors.........

John Devaney Chairman Kent Atkinson Chairman of Audit Committee Derek Bonham* Ian Clubb(1) Chairman of Remuneration Committee Kathleen Flaherty(1) Werner Koepf </Table> --------------- (1) Ian Clubb and Kathleen Flaherty have agreed to become members of the Corp Board on Listing of the New Shares, the New Notes and the Warrants. They are not, and have not agreed to become members of the plc Board. * Member of the Board of plc only. Please refer to the Group's announcements dated 14 November 2002, 16 December 2002 and 14 March 2003 for full details of these board changes. FINANCIAL RESTRUCTURING On 29 August 2002, plc announced that it had concluded non-binding indicative heads of terms (the "Heads of Terms") for the financial restructuring of plc and its wholly owned subsidiary Corp (the "Restructuring"). On 13 September 2002, plc announced that, in accordance with the Heads of Terms, interim security over the balance of the lockbox accounts established in April 2002 had been granted in favour of the Group's Syndicate Banks, bondholders (including the Bond trustees) and certain ESOP Derivative Banks. On 16 December 2002, plc concluded modifications to the Heads of Terms. The terms of the Restructuring as updated by these modifications were in most respects, including the initial cash distribution, the same as those announced by plc on 29 August 2002. On 7 February 2003, plc announced that Corp and plc had reached agreement in principle with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group. Documentation reflecting this settlement has now been concluded. As a result of this settlement, the initial cash distribution to be made as part of the Restructuring is to be increased by L135 million, in return for a L123 million reduction in the face value of the New Junior Notes to be issued as part of the Restructuring (ie equivalent to redemption at 110 per cent. of face value). In the 7 February 2003 announcement, plc also indicated that the initial cash distribution was to be increased by an additional L20 million (to a total of L320 million) in replacement of the surplus cash element of the excess cash mechanism outlined in the Group's announcement of 16 December 2002. This L320 million figure is in addition to L95 million which, as previously announced, has already been paid on interest accrued on Corp financial debt in the period to 15 October 2002. Further proposed changes to the Restructuring were announced on 18 March 2003. In particular, plc announced proposed modifications to the scheme consideration including an increase in the face value of the New Junior Notes to the sum of US$ 300 million and the US dollar equivalent of approximately L117 million and a proposal that the limited recourse notes no longer be issued, as well as a further increase to the initial cash distribution of 531

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- an additional L20 million (to a total L340 million). The Group further announced that documentation for the proposed schemes of arrangement has been filed with the High Court of England and Wales and that scheme documentation is expected to be posted to creditors by 31 March 2003, with Restructuring targeted to be completed by 31 May 2003. RECENT DEVELOPMENTS On 24 February 2003, plc announced that, following approval from the High Court in the United Kingdom, Corp had completed a return of capital from Ultramast Limited (a joint venture with Railtrack Telecom Services Limited) and settled all outstanding litigation relating to the joint venture company set up in December 2000 with RT Group plc. As a result of the transaction, plc received cash proceeds of approximately L41 million (L20 million of which Corp had previously paid into court). On 5 March 2003, plc announced that it had completed, in separate transactions, the disposal of two of the businesses from its Capital portfolio. First, the disposal of the Group's Private Mobile Networks division (also known as TETRA) to Finmeccanica SpA for approximately L2 million in cash, approximately L4.8 million in assumed financial debt and approximately L8.2 million in assumed debt to suppliers, and second, the disposal of Marconi Online to Coca Cola Amatil (N.Z.) Limited for approximately L1 million. OUTLOOK The market for telecommunications equipment and services remains difficult. During the first three quarters of the current financial year the annualised rate of Core sales has declined by around 10 per cent from approximately L2 billion in the first quarter to approximately L1.8 billion in the third quarter. Corp and plc do not expect that the Group will benefit from a seasonal uplift in Core sales during the fourth quarter of the financial year compared to the level recorded in the third quarter (L456 million), contrary to the seasonal pattern of customer demand in previous years. Furthermore, Corp and plc believe that market volumes are likely to contract further during the next financial year and do not expect to benefit from significant market share gains. As a result, the Group believes that Core sales could decline by up to a further 5 per cent during the next financial year compared to the annualised third quarter trading levels (L1.8 billion). In December 2002, the Group outlined its Core operating model and confirms its targets to achieve a gross margin run-rate in the range of at least 24 to 27 per cent of Core sales and an operating expenditure run-rate in the range of 21 to 24 per cent of Core sales during the next financial year ending 31 March 2004. The Group now believes that it will be able to reduce the Core operating cost base to an annual run rate below L450 million during the next financial year and thereby reduce its targeted breakeven level of sales to below L1.7 billion. 532

However, as these accounts are not statutory financial statements, the Group has not applied all of the requirements of the Act or of accounting standards in relation to items of disclosure including, but not limited to retirement benefits, financial instruments and directors' emoluments. The last actuarial assessment of the Group's defined benefit pension 536

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- scheme liabilities and valuation of pension assets was performed at 30 September 2002 and has not been updated for the quarter ended 31 December 2002. Consequently, no amounts have been recognised in the Statement of Total Recognised Gains and Losses for movements in the actuarial position of plan assets and plan liabilities. Unless otherwise stated, references to "Group" in the trading section of this Financial Review refer to the Group including its share of joint ventures, but excluding its share of results of associates. The Group currently consists of plc and its subsidiaries, including Corp. After completion of the proposed financial restructuring (see Financial Restructuring above), Corp will replace plc as the parent company of the Group. The major profit and loss differences between the unaudited consolidated results of plc and Corp for the third quarter ended 31 December 2002 were: - plc's share of the fees paid to advisers in connection with the Restructuring which have been charged to operating exceptional items (L8 million); and - interest payable of L1 million on the bonds issued by Corp held by Ancrane, a subsidiary of plc that does not form part of the Corp group; The major balance sheet differences between the unaudited consolidated financial position of plc and Corp as at 31 December 2002 were: - cash of L1 million held by plc; and - net balances of L660 million of Corp bonds and other balances held by members of the plc group that are not members of the Corp group with members of the Corp group. Throughout this Operational and Financial Review, the term: - "adjusted gross profit" refers to gross profit before an exceptional credit of L7 million (Q3 2002: L19 million exceptional charge) as disclosed in Note 5a; - "adjusted operating profit/(loss)" refers to operating profit/(loss) before exceptional charges of L54 million (Q3 2002: L94 million) as disclosed in Note 5a and goodwill amortisation of L28 million (Q3 2002: L46 million) as disclosed in note 4; - "adjusted operating cost run-rates" and "adjusted operating expenses" refer to operating cost run rates and operating expenses before exceptional charges of L60 million (Q3 2002: L75 million) as disclosed in note 5a and goodwill amortisation of L28 million (Q3 2002: L46 million) as disclosed in note 4; - "adjusted operating cash flows" refers to operating cash flows before exceptional cash outflows of L82 million (Q3 2002: L107 million) and after net capital expenditure of L3 million inflow (Q3 2002: L29 million inflow). GOING CONCERN There is no guarantee that the negotiations relating to the Restructuring (discussed above) will reach a satisfactory conclusion. However, in the light of the information currently available to them, Corp and plc believe that the Group's bankers, bondholders and other creditors will support the Group in achieving an appropriate capital structure and that all the conditions for the Restructuring will be satisfied. On this basis, plc considers it appropriate to prepare the accounts on a going concern basis. Should the Group's bankers, bondholders and other creditors (or some of them) cease to support the Group before the completion of the Restructuring, or should all of the conditions for the Restructuring not be met, adjustments would be necessary to record additional liabilities and to write down assets to their recoverable amount. It is not practicable to quantify with reasonable accuracy these possible adjustments. APPLICATION OF CRITICAL ACCOUNTING POLICIES Corp and plc prepare their financial statements and accompanying notes in accordance with UK GAAP. One of the notes to these financial statements, included in this document, describes the significant accounting policies used in their preparation. The preparation of such non-statutory financial statements requires Corp and plc to 537

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- make estimates, judgements, and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Corp and plc base their estimates on historical experience and various other assumptions that they believe are reasonable under the circumstances, the results of which form the basis for making judgements about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Corp and plc believe that the following are some of the more critical judgement areas in the application of its accounting policies that affect their financial position and results of operations. The development and selection of these critical accounting estimates has been discussed with Corp is and plc's audit committees. REVENUE RECOGNITION Revenue is recognised when all of the following conditions are satisfied 1) there is persuasive evidence that an arrangement exists; 2) delivery has occurred or services have been rendered; 3) the fee is fixed or determinable; and 4) it is probable that the debtor will be converted into cash. It is common for the Group's sales agreements to cover the delivery of several products and/or services. These range from arrangements where a contract covers the delivery and installation of equipment to more complex arrangements, which also include training of customer personnel, sale of software and other support services. Revenue from contracts with multiple element arrangements, such as those including installation and commissioning services, is recognised as each element is earned based on objective evidence of the relative fair values of each element and when there are no undelivered elements that are essential to the functionality of the delivered elements. Revenues and estimated profits on long-term contracts are recognised under the percentage-of-completion method of accounting using a cost-to-cost methodology. Significant judgement is required in determining progress toward completion and in estimating revenues and costs. Profit estimates are revised periodically based on changes in facts in the underlying contract. When estimates of total contract revenues and costs indicate a loss, a provision for the entire amount of the contract loss is recognised in the period in which the loss becomes foreseeable. Advance payments received from contracts are recorded as a liability unless there is a right of set-off against the value of work undertaken. IMPAIRMENT OF LONG-LIVED ASSETS The Group reviews the carrying value of other fixed assets and assets to be disposed of, including other intangible assets, whenever indicators of impairment exist. Indicators of impairment include (but are not limited to): a. a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition; b. a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; and c. a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. These tests for impairment require significant judgements in determining estimates of future cash flows and the resulting value in use of the relevant fixed asset. Estimations of the present value of future cash flows contain inherent uncertainty and include estimates of market size and market share information, growth rates, product demand and technological development, costs of labour and supplier purchases, working capital requirements, and discount rates to be applied to future cash flows. If the carrying value of a fixed asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the fixed asset exceeds the higher of its net realisable value or its value-in-use. In the three months ended 31 December 2002 and 2001, Corp and plc recorded impairment charges in relation to tangible fixed assets of L9 million and Lnil million, respectively. In the year ended 31 March 2002, Corp and plc 538

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- recorded an impairment charge relative to goodwill of L3,677 million. The Group believes that its estimates of future cash flows are reasonable; however, changes in such estimates could affect the determination of the net realisable value or its value-in-use of the relevant fixed asset. CONTINGENT LIABILITIES Corp and plc are subject to legal proceedings and other claims arising in the ordinary course of business. Various claims and proceedings have been or may be instituted or asserted against Corp and plc relating to class shareholder actions and the conduct of its business, including those pertaining to patents, environmental, safety and health, employment and contract matters. Corp and plc are required to assess the likelihood of any adverse judgements or outcomes to these matters, as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is based on a careful analysis of each individual issue where appropriate with the assistance of outside legal counsel. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavourably to Corp and plc, the Group believes that the ultimate outcome of these matters will not have a material adverse effect on the results of operations or financial position or cash-flows of Corp and plc, except as discussed in Note 21 to the non-statutory financial statements. PENSION AND OTHER POST-RETIREMENT BENEFITS Pension and other post-retirement benefits costs and obligations are dependent on actuarial assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on plan assets, mortality rates, and other factors. While the Group believes that the assumptions used are appropriate, the assumptions used may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants. These differences may result in a significant impact on the amount of future pension or post retirement benefits expense and the resulting liability. In the three months ended 31 December 2002, the Group charged the profit and loss account with L6 million of service cost and L2 million of notional interest in respect of defined benefit schemes on the basis of the 30 September 2002 actuarial assessment. This will be updated during the final quarter of the year ending 31 March 2003, and any actuarial gains and losses arising on pension assets and liabilities in the balance sheet will be shown in the statement of total recognised gains and losses for the year ending 31 March 2003. The comparative period for the three months 31 December 2001 was based on actuarial and investment reviews carried out between 1 January 2002 and 31 March 2002. PRODUCT WARRANTIES Provisions for estimated expenses related to product warranties are made at the time products are sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims. The Group actively studies trends of warranty claims and takes action to improve equipment quality and minimise warranty claims. The Group believes that the warranty reserve is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the reserve. If Corp and plc were to experience an increase in warranty claims compared with its historical experience, or if costs of servicing warranty claims were greater than the expectations on which the accrual had been based, the Groups' gross margins could be adversely affected. REPORTING STRUCTURE For financial reporting purposes, the Group divides its continuing operations into two segments: Core and Capital. Core is further analysed by business-type: Network Equipment, comprising Optical Networks, Broadband Routing and Switching (BBRS), European Access, North American Access, Outside Plant & Power (OPP) and Other Network Equipment; and Network Services comprising Installation, Commissioning & Maintenance (IC&M) and Value-Added Services (VAS). 539

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Capital comprises businesses which Marconi manages to create value and ultimately for disposal. During the third quarter ended 31 December 2002, Capital included the Group's Tetra and UMTS mobile activities, Marconi Online and other smaller joint ventures and investments. In the comparative period of the previous financial year, Capital also included Marconi Applied Technologies. In addition, the Group has an economic interest of 71.6 per cent, but voting rights of only 49.6 per cent, in Easynet Group Plc ("Easynet"). This investment is managed through the Group's Capital division, but is accounted for as an associate in the Group's consolidated accounts. None of the Group's businesses were reported as discontinued operations during the third quarter. Discontinued operations in the previous financial year included Strategic Communications as well as Medical, Commerce and Data Systems until the date of their respective disposals. As part of the proposed Restructuring, it is intended that the Group will segment its business along geographic lines and report the equipment and services activities of BBRS, OPP and North American Access (US businesses) separately from the Group's businesses based in Europe and the Rest of the World, which comprise Optical Networks, European Access, Other Network Equipment and the rest of Network Services. As previously disclosed in plc's announcement of 29 August 2002, OPP and North American Access are being managed for value and with a view to disposal, the proceeds of which would be used to redeem in part the Junior Notes proposed as part of the Restructuring (or in the event of disposal prior to 1 May 2003, to reduce the amount of Junior Notes issued).

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Sales from continuing operations amounted to L466 million, a decrease of L282 million or 38 per cent compared to the third quarter of the previous year. This decrease was mainly the result of continued reductions in capital expenditure in the global market for telecommunications equipment and services resulting in lower sales in the Group's Core business (see Core Business Review below). Sales in the Group's Capital business have been substantially reduced since the third quarter of the previous year as a result of business disposals, the major component of which was the disposal of the Group's 50 per cent stake in General Domestic Appliances. The L12 million sales in Capital during the period related to the Group's Mobile Tetra business and represented a L4 million increase compared to the third quarter of the previous year as a result of an increase in sales of Tetra products outside the domestic Italian market, particularly in APAC and CALA. There were no sales from discontinued operations during the period. The L293 million of sales from discontinued operations for the three months ended 31 December 2001 related to disposed businesses, Strategic Communications, Data, Commerce and Medical Systems.

The L139 million decrease compared to the third quarter of the previous year reflected mainly the loss of gross profit attributed to business disposals from discontinued operations (L98 million) and from Capital (L20 million). The L21 million reduction in the Core business related mainly to the lower sales volumes in Network Equipment described in the Core Business Review below. GROUP ADJUSTED OPERATING PROFIT/(LOSS) BY SEGMENT <Table> <Caption> 3 MONTHS ENDED 31 DECEMBER ---------------- IN L MILLION 2002 2001 ------------ ---- ---- <S> <C> <C> Core (41) (128) Capital (10) (7) CONTINUING OPERATIONS (51) (135) DISCONTINUED OPERATIONS -- 26 GROUP (51) (109) </Table> Group adjusted operating loss was reduced by L58 million from a loss of L109 million in the third quarter of the previous year to a loss of L51 million in the reporting period. Operating cost savings achieved in the Core business described in the Core Business Review below were the main driver of the Group's improved operating performance and more than offset the absence of L26 million of adjusted operating profit recorded in the previous year relating to discontinued operations. 541

Sales fell across all major geographic regions as a result of the significant reductions in capital expenditure by the majority of telecom operators world-wide. On a sequential basis, the quarter-on-quarter decline in sales was limited to L26 million or 5 per cent (Q2 2003: L482 million). Core sales in EMEA fell by L76 million or 21 per cent to L287 million (Q3 2002: L363 million. L56 million representing almost three-quarters of this decline occurred in Optical Networks as telecom operators have concentrated their reduced capital expenditure on maximising utilisation in their existing networks to the detriment of new network build. A further L10 million of this decline occurred in BBRS mainly as a result of the expiry of a third party distributorship agreement in the United Kingdom during the current financial year. Sales of Network Services in EMEA increased as a result of the phasing of long-term service contracts particularly in the Middle East, UK and Germany. Core sales in the US fell by L40 million or 24 per cent to L127 million (Q3 2002: L167 million). This was mainly a result of reduced sales of OPP equipment and services following substantial reductions in capital expenditure by US telecom operators. US sales of Optical Networks amounted to less then L1 million during the period (Q3 2002: L7 million) following the Group's decision to cease the development and manufacture of its SONET product range in April 2002. In APAC, Core sales declined by L32 million or 52 per cent to L29 million (Q3 2002: L61 million). The main area of decline was Optical Networks and this was mainly a result of the lower level of sales recorded in China following the completion of large network build projects in the region in the previous financial year and delays to certain network build projects by a number of the Group's Chinese customers in the current financial year. Sales of Network Services were also down in the region mainly as a result of business disposals. Core sales in CALA were down L28 million or 68 per cent to L13 million (Q3 2002: L41 million). Sales were down across all product and service activities as a result of the deterioration in economic conditions compared to the prior year period and the consequent reductions in capital expenditure by most of the major telecom operators in the region. 542

NETWORK EQUIPMENT Sales of Network Equipment amounted to L261 million, a decline of L146 million or 36 per cent compared to the previous year (Q3 2002: L407 million). Significant reductions in capital spending by the majority of telecommunications operators world-wide was the primary reason behind the lower level of sales across all major product areas. This trend was particularly marked in Optical Networks and Outside Plant and Power equipment. In some product areas, particularly European Access, the trend was further exacerbated by the impact of product line rationalisations undertaken in April 2002 as part of the Group's operational restructuring. Optical Networks Optical Networks sales declined by L93 million, or 49 per cent to L96 million (Q3 2002: L189 million). Sales were down in all major geographic regions. Over half of the decline in sales arose in EMEA. In the United Kingdom, the drop in sales was caused by the substantial decline in demand from second tier operators, partially offset by slightly higher sales to BT. During the third quarter, the Group has begun discussions with a number of second tier operators, who are now beginning to emerge from their own restructuring initiatives, with regard to their future network plans but this has not yet translated to firm sales. Sales to major German customers were lower than in the third quarter of the previous year as a result of lower capital spending amongst operators. Sales were also lower in Italy due to the phasing of the roll-out of Telecom Italia's DWDM network, where the third quarter of the previous year was a peak stage in the deployment of the Group's PLT products. In APAC, whilst sales into the Australian market increased as a result of SDH Series 3 sales to Telstra, sales in China were down partly due to the completion of DWDM sales to China Railcom for the North-West Ring project during the last financial year but also as a result of the difficult conditions in the Chinese market. In CALA, third quarter capital spending by telecom operators remained at a very low level and this led to reduced Optical Networks sales volumes compared to the previous year. Third quarter Optical Networks sales in the US were not material, following the Group's decision during the first quarter of the financial year to cease the development of its SONET products for the US market and the subsequent closure of its North American manufacturing plant. 543

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- During the third quarter, SDH accounted for 89 per cent of Optical Networks sales (Q3 2002: 91 per cent) and DWDM for 7 per cent (Q3 2002: 9 per cent). The balance related mainly to network management systems. Broadband Routing and Switching (BBRS) Sales of BBRS equipment decreased by L8 million or 20 per cent to L32 million (Q3 2002: L40 million). The expiry of a distributorship agreement in EMEA earlier in the current financial year, through which the Group sold a third party's equipment into the UK market, was the main cause of this decline. Sales in the US remained stable compared to the third quarter of the previous year mainly as a result of the consistent seasonal pattern of spending by the US Federal Government, the largest single customer of the Group's BBRS business. European Access European Access sales fell by L16 million or 19 per cent to L69 million (Q3 2002: L85 million). Reductions in capital spending by a number of European Access customers, particularly second-tier operators in the United Kingdom and Germany, as well as rationalisation of the Group's legacy product lines following a strategic review of the Access portfolio in April 2002 were the primary reasons behind this decline. Sales of voice systems increased largely due to a software upgrade and the Group recorded higher sales of its Access Hub compared to the modest initial sales of this newly launched product platform in the third quarter of the previous year. These increases were more than offset by lower sales of fixed wireless access products mainly as a result of significant reductions in capital spending by a number of German mobile operators and lower sales of other legacy and discontinued products. North American Access At L23 million, North American Access sales remained relatively stable compared to the third quarter of the previous year fell (Q3 2002: L24 million). This was mainly the result of the continued deployment of equipment into BellSouth's access network. Outside Plant & Power (OPP) OPP equipment sales fell by L18 million or 38 per cent to L30 million (Q3 2002: L48 million). This was a result of the significant reductions in capital spending in the United States and CALA. Other Network Equipment Other Network Equipment declined by L10 million or 48 per cent to L11 million. While Interactive Systems recorded a modest increase in sales, this was more than offset by declining revenues from legacy businesses, particularly in EMEA. NETWORK SERVICES Sales of Network Services decreased by L30 million or 13 per cent to L195 million (Q3 2002: L225 million). This was driven by decline in sales of Installation, Commissioning and Maintenance activities, particularly in the US, while sales of Value Added Services remained stable. Installation, Commissioning and Maintenance (IC&M) IC&M sales fell by L29 million or 24 per cent to L93 million. Some 65 per cent of the decline arose in the US market and related to both OPP where sales of services fell in line with declines in equipment sales and to enterprise-specific service projects in the region as the Group continues to refocus activities on the service-provider market. IC&M sales in EMEA remained stable compared to the third quarter of the previous year mainly as a result of ongoing long-term support contracts which typically account for approximately 40 per cent of IC&M sales in the region and which provide a more constant revenue stream. In addition, the Group continues to benefit from new business opportunities such as long-term support, repair and maintenance contracts as a result of increased outsourcing of services by major European telecom operators. Major service contracts were won or 544

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- renewed with BT, Ericsson, Netcologne and Belgacom during the quarter and these revenue streams were sufficient to offset lower levels of installation and commissioning activities associated with sales of Network Equipment. Value-Added Services (VAS) At L102 million, the Group recorded stable sales of Value-Added Services compared to the third quarter of the previous year (Q3 2002: L103 million). Sales were down in Managed Services as a result of the Group's exit from its IT outsourcing activities completed during December 2002 and in the APAC region as a result of the sale of part of the Group's Hong Kong based legacy operations in October 2002. Sales of Wireless Services and BBRS-related services remained stable while sales of Integrated Systems increased compared to the third quarter of the previous year mainly as a result of the phasing of long-term service contracts in the UK, the Middle East and in Germany. CORE SALES CHANNELS The Group sells its products and services through its direct sales force and also through indirect channels such as local partners or distribution partners such as Ericsson, Italtel, Nokia and Siemens. Sales through channel partners were significantly lower than the third quarter of the previous year as a result of the overall reduction in market volumes and particularly, in the case of sales through Ericsson and Nokia, as a result of the completion of 2G and 2.5G wireless network rollouts in the previous year and the ongoing delays to the deployment of 3G network rollouts. CORE PRICING A high proportion of Core sales, particularly in Europe, are derived from existing frame contracts, which typically contain annual price reductions. The Group estimates that price erosion in Network Equipment under such contracts ranges up to 8 per cent on an annual basis. The Group aims to continue to match this price erosion with planned product cost savings to avoid erosion of gross margins. Network Services tends to be more resilient to price erosion. During the period, the Group has observed increased pricing pressure when competing for new business in certain territories (particularly in China) and in certain product areas (particularly Access and DWDM). CORE KEY CUSTOMERS The Core business serves a strong customer base of predominantly incumbent operators and government agencies. The ten largest customers during the third quarter were BellSouth, BT, Ericsson, Metro City Carriers, Telecom Italia, Telkom South Africa, UK Government, US Federal Government, Verizon and Vodafone Group. In aggregate, these customers accounted for 46 per cent of third quarter Core sales (Q3 2002: ten largest customers 36 per cent). BT remains the Group's largest customer and accounted for 19 per cent of Core sales in the third quarter (Q3 2002: 13 per cent). In EMEA, the five largest customers during the third quarter were BT, Telecom Italia, Telkom South Africa, the UK Government and Vodafone Group and in aggregate accounted for 49 per cent of Core sales in the region during the period (Q3 2002: top 5 EMEA customers accounted for 41 per cent). In the US, the five largest customers during the third quarter were BellSouth, Qwest, SBC, the US Federal Government and Verizon and in aggregate accounted for 52 per cent of Core sales in the region during the period (Q3 2002: top 5 US customers accounted for 35 per cent). The increased concentration of sales resulted from the decline in the number of second tier operator and enterprise customers compared to the third quarter of the previous year. 545

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- CORE COST OF SALES Core cost of sales in the third quarter amounted to L355 million (Q3 2002: L510 million). Of this, approximately 57 per cent related to Network Equipment (Q3 2002: 64 per cent) and 43 per cent to Network Services (Q3 2002: 36 per cent). In Network Equipment, approximately 75 per cent of cost of sales is material costs, around one-third of which relates to outsourced printed circuit board (PCB) assemblies. The remaining 25 per cent relates to in-house labour and overhead and includes functions and costs such as planning, supplier management, supply chain management, logistics, engineering, quality control, final assembly and test, property costs, asset depreciation, system maintenance and warranty costs. The decrease in cost of sales in Network Equipment is due to substantial cost savings achieved in both the European supply chain and in the Group's US manufacturing operations. In Europe, material, labour and overhead costs have been significantly reduced year on year and additional savings achieved through asset disposal, site rationalisation and warehouse closures. In the US, three factories have been closed during the current financial year and other plants rationalised in line with the reduced level of sales volumes. In Network Services, over 60 per cent of cost of sales relates to the cost of in-house labour. The balance relates to the cost of sub-contract labour, materials and other overheads. The reduced costs compared to the previous year relate mainly to headcount reductions. CORE ADJUSTED GROSS PROFIT / MARGIN The Group continued to make good progress in its initiatives to improve gross margins during the period. Third quarter Core adjusted gross profit amounted to L101 million, or 22.1 per cent of sales. The decrease in adjusted gross profit compared to the previous year (Q3 2002: L122 million) related mainly to the reduced volume of Network Equipment sales, and particularly the lower level of sales in Optical Networks. This was partially offset by cost savings achieved in the Group's European supply chain during the period as a result of further rationalisation and benefits of improved procurement. These savings were the main contributing factor to the increase in adjusted gross margin as a percentage of sales compared to the previous year (Q3 2002: 19.3 per cent of sales). On a sequential basis, excluding the impact of L25 million of additional stock provisions charged to cost of sales in the second quarter, adjusted gross profit in the Core remained relatively stable despite the 5 per cent sequential sales decline (Q2 2003: adjusted gross profit L104 million reduced to L79 million after additional stock provisions). This was achieved through cost savings realised during the period in both Network Equipment and Network Services. These savings were the main drivers of the sequential improvement in adjusted gross margin as a percentage of sales in the quarter (Q2 2003: 21.6 per cent of sales before the impact of additional stock provisions of L25 million). They accounted for a 3 percentage point increase in Core adjusted gross margin, which was partially offset by a less favourable business mix (0.5 percentage point decrease) and one-off items relating to contract completions (2 percentage point decrease). CORE ADJUSTED OPERATING EXPENSES During the third quarter, operating cost reduction remained a key focus of the Group's strategy. Core adjusted operating expenses totalled L142 million or 31 per cent of Core sales during the period, a reduction of L108 million or 43 per cent compared to the third quarter of the previous year (L250 million; 40 per cent of Core sales). Significant savings were achieved across all main categories of operating expenditure. By 31 December 2002, the Group had reached an annualised adjusted operating cost run-rate in the Core business of approximately L550 million, reduced from L1.1 billion at the end of September 2001 and L635 million at the end of September 2002. 546

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- CORE OPERATING EXPENSES -- RESEARCH & DEVELOPMENT (R&D) Core R&D expenditure (before exceptional items) amounted to approximately L64 million, a 12 per cent reduction compared to the previous quarter (Q2 2003: L73 million), and a 44 per cent reduction compared to the third quarter of the previous financial year (L115 million). Cost savings achieved during the quarter related mainly to headcount reductions and reduced facility costs as well as reduced spend on development materials and a reduced level of depreciation following exceptional asset write-downs relating to development models in prior periods. Optical Networks accounted for approximately 40 per cent of the total Core R&D spend during the third quarter (Q3 2002: approximately 36 per cent). Around half of this spend was focused on SDH and in particular the release into customer trials of the Group's new high-capacity SDH platform (MSH2K, MSH64c) and the development of further enhancements to the data-handling capability of the Group's next generation low-capacity SDH platform, the SMA Series 4. The Group also continued to invest in DWDM, targeting feature enhancements across the Group's existing platforms for Core and Metro applications and further upgrades to the Group's network management software. R&D spend across the Group's Access portfolio, in Europe and North America combined, accounted for a further 23 per cent of total Core R&D (Q3 2002: approximately 32 per cent). The Group has further cut spend on legacy products in North America and Europe to focus on R&D programmes relating to Fixed Wireless Access products, the Access Hub and the recently launched Softswitch. BBRS accounted for 21 per cent of Core R&D in the quarter (Q3 2002: approximately 17 per cent). Over 50 per cent of this spend was focused on the further development of the Group's multi-service core switch-router, the BXR-48000. Other ongoing initiatives include further enhancements to the Group's ASX1000 and ASX4000 product ranges and the Group's ViPr project, a virtual presence desk-top networking terminal which uses The Group's ATM-based multi-service broadband switch-routing platforms as transport infrastructure. The remaining 16 per cent of R&D spend in the period related mainly to OPP, wireless software and Other Network Equipment. CORE OPERATING EXPENSES -- SALES & MARKETING Core Sales & Marketing expenditure (before exceptional items) amounted to L59 million, a 2 per cent reduction compared to the previous quarter (Q2 2003: L60 million), and a 45 per cent reduction compared to the third quarter of the previous financial year (L107 million). Cost savings during the quarter have been achieved mainly through further headcount reductions, a reduced level of discretionary marketing spend and the closure of overseas sales offices. CORE OPERATING EXPENSES -- ADJUSTED ADMINISTRATIVE Adjusted administrative expenses (before goodwill amortisation and exceptional items) in the Core amounted to L22 million, a 27 per cent reduction compared to the previous quarter (Q2 2003: L30 million), and a 45 per cent reduction compared to the third quarter of the previous financial year (L40 million). Cost savings during the quarter have been achieved mainly through further headcount reductions, site rationalisation (including the relocation of the Group's UK head office) and reduced spend on professional fees incurred in the normal course of business. Professional fees relating to the Group's financial restructuring are classified as exceptional costs. CORE OPERATING EXPENSES -- OTHER Other Core operating income amounted to approximately L3 million and related mainly to income from properties and royalties as well as a net favourable foreign exchange translation gain. (Q2 2003: L6 million operating expense; Q3 2002: L12 million operating income). 547

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- CORE ADJUSTED OPERATING LOSS <Table> <Caption> FY03 FY02 ------------------------------------------ ------------ Q1 Q2 Q3 Q3 ------------ ------------ ------------ ------------ IN L MILLION <S> <C> <C> <C> <C> Network Equipment (96) (83) (49) (80) Network Services (2) 7 20 (32) Other* (17) (14) (12) (16) CORE (115) (90) (41) (128) </Table> --------------- * Other relates mainly to Head Office and other central costs The Group significantly reduced the adjusted operating loss in its Core business to L41 million during the third quarter, compared to an adjusted operating loss of L90 million in the previous quarter and an adjusted operating loss of L128 million in the third quarter of the previous year. This substantial improvement was driven by a combination of increased gross margin and reduced operating expenditure resulting from the Group's ongoing operational cost saving initiatives described above. Network Equipment The adjusted operating loss in Network Equipment amounted to L49 million, an improvement of L34 million or 41 per cent compared to an adjusted operating loss of L83 million in the previous quarter and an improvement of L31 million or 39 per cent compared to an adjusted operating loss of L80 million in the third quarter of the previous year. Substantial cost reductions achieved in the Group's supply chain and manufacturing operations in Europe and the US as well as in all areas of operating expenditure were the main driver of this improvement and more than offset the reductions in sales volumes across Network Equipment. Network Services Network Services recorded a marked increase in adjusted operating profit from L7 million in the second quarter of the financial year to L20 million during the period despite the stable sequential sales profile. This represented a significant increase compared to the third quarter of the previous year when Network Services recorded an adjusted operating loss of L32 million. Improved resource utilisation and other ongoing cost reduction initiatives were the main drivers behind this enhanced performance. The most marked progress was recorded in IC&M as a result of increased efficiency and an improved ratio of in-house to sub-contracted labour, giving rise to greater flexibility in the work-force. OTHER FINANCIAL ITEMS EXCEPTIONAL ITEMS Operating Exceptionals For the three months to 31 December 2002, exceptional items charged to Group operating loss (including joint ventures) totalled L54 million. Of this amount L7 million was credited to restructuring costs classified within cost of sales and L61 million was charged to administrative expenses. The L7 million exceptional income arose as a consequence of the Group's manufacturing outsourcing arrangements whereby plc was able to release stock provisions where the corresponding components, previously provided for by the Group, had been utilised by the Group's outsourcing partner. The L61 million charge, related mainly to exceptional restructuring and reorganisation costs, comprising costs associated with the Group's operational restructuring including headcount reductions (L32 million), site rationalisation (L5 million) and fixed asset impairments (L11 million) as well as costs associated with the Group's financial restructuring (L20 million). These charges were partially offset by a L7 million exceptional gain due to lapses of share options granted to vendors of past acquisitions (MSI and Mariposa). 548

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- In addition, the Group recorded its share of associates' operating exceptional charges, which amounted to L3 million during the quarter. During the three months to 31 December 2001, exceptional items charged to Group operating loss (including joint ventures) totalled L94 million and related wholly to the Group's operational restructuring. Non-Operating Exceptionals For the three months to 31 December 2002, non-operating exceptional charges amounted to L10 million, which related mainly to the disposals of the Group's legacy operations in South Africa and wireless operations in APAC as well as to the write down of fixed asset investments. During the three months to 31 December 2001, non-operating exceptional income amounted to L341 million and related mainly to gains on disposals of subsidiaries and other fixed assets including Medical Systems, properties and the Group's stakes in Sietel and Lottomattica as well as the mark to market of some of the Group's other investments, namely Lagardere (since disposed) and Easynet. INTEREST AND FINANCE INCOME In the three months to 31 December 2002, the Group's net interest charge to the Profit and Loss Account was L51 million (Q3 2002: L66 million). The charge during the period mainly comprised interest paid and accrued on the Group's bond and bank debt (L60 million). These charges were partially offset by interest received on the Group's cash balance and in relation to the tax repayment received during the period (L4 million). Finance income amounted to L7 million. TAXATION The tax charge during the period was Lnil (Q3 2002: Lnil). GOODWILL AMORTISATION The Group incurred a charge of L28 million for goodwill amortisation for the three months to 31 December 2002 compared to a charge of L46 million in the corresponding period of the previous year. This significant reduction was a result of the reduced carrying value of goodwill on the Group's balance sheet following the exceptional goodwill impairment charges in the year ended 31 March 2002 and the disposal of businesses and related goodwill. ASSOCIATES The charge of L11 million for the three months ended 31 December 2002 represents the Group's share of operating losses and exceptional items of Easynet as well as the amortisation of related goodwill. The charge in the three months ended 31 December 2001 was L11 million. EARNINGS PER SHARE Basic and diluted loss per share, which reflects goodwill amortisation and exceptional items, was 7.1 pence (Q3 2002: earnings of 2.7 pence). The loss per share excluding goodwill amortisation and exceptional items was 3.6 pence compared to earnings per share of 4.4 pence in the third quarter of the previous year. DIVIDEND In the light of the Group's ongoing financial restructuring, the Board has decided not to propose the payment of a dividend for the year ending 31 March 2003. Furthermore, after the Restructuring, Corp will be restricted from 549

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- paying dividends under the terms of the indentures governing the New Notes. Accordingly Corp does not expect to pay a dividend in the foreseeable future. FINANCIAL CONDITION BALANCE SHEET Net Assets/Liabilities As at 31 December 2002, net liabilities before net retirement benefit deficits stood at L2,285 million compared to L2,104 million at 30 September 2002. The L181 million increase in net liabilities was due to the loss incurred during the period partially offset by favourable foreign exchange translation movements. Fixed Assets The L638 million of goodwill on the balance sheet at 31 December 2002 relates mainly to the acquisitions of GPT and Reltec and businesses acquired from Nokia and Bosch. The decrease of L34 million from L672 million at 30 September 2002 related mainly to the amortisation charge during the period (L28 million) and foreign exchange translation movements. Tangible assets decreased by L49 million from L329 million at 30 September 2002 to L280 million at 31 December 2002. This was mainly due to depreciation (L28 million), fixed asset disposals (L19 million) and fixed asset impairments as a result of the downsizing and restructuring of the Core business (L9 million). The fixed asset disposals related mainly to the disposal of the Group's legacy South African operations and various properties in EMEA and APAC. Capital expenditure during the period was restricted to items essential to support the business. Investments decreased by L15 million from L121 million at 30 September 2002 to L106 million at 31 December 2002. This was mainly due to the Group's share of the losses of joint ventures and associates and the write down of one of the Group's other investments in Australia, offset by an increase in the value of the Group's investment in Bookham Technology plc which was marked to market at the end of the reporting period. Working Capital The Group made particularly strong progress in its initiatives to improve working capital management during the period. At Group level, net stock and contracts in progress reduced by approximately L51 million to L305 million. This was driven primarily by reductions in the Core where net stock and contracts in progress fell by L47 million. These reductions were achieved mainly through improved control and alignment of inventory in-feed with forecast sales demand, improvements in inventory management practices and the continued rationalisation of stock locations. The increase in Core net stock turns from 5.1 in September 2002 to 6.3 in December 2002 reflected this improved utilisation and management of inventory. Group net debtors decreased by approximately L115 million to L747 million. In the Core, net debtors decreased by approximately L116 million to L726 million. L76 million of the decrease in the Core related to net trade debtors partly as a result of the reduced trading volumes during the period and partly as a result of the Group's continued focus on the management of debtor collection and overdue debts. Net Core trade debtor days decreased from 107 in September 2002 to 100 in December 2002, reflecting the Group's continued focus on cash collections, particularly in Northern Europe and Middle East and in businesses in Network Services. Other debtors and prepayments in the Core decreased by L39 million to L151 million mainly as a result of the release and unwind of advances and prepayments. Trade, other creditors and accruals fell from L1,142 million at 30 September 2002 to L1,090 million at 31 December 2002, a reduction of L52 million. Trade creditors in the Core were reduced by L37 million to L225 million. Core trade creditor days remained stable at approximately 54 days. Other Creditors, accruals and prepayments on contracts in the Core reduced by L63 million to L442 million. This was mainly due to a lower 550

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- level of contract and payroll-related accruals as a result of the reduced size of the Core business as well as to the settlement of a legal dispute in the field of IT. Provisions Provisions for liabilities and charges stood at L452 million at 31 December 2002, a net reduction of L4 million compared to L456 million at 30 September 2002. Share option provisions amounted to L167 million (September 2002: L176 million). The net reduction of L9 million in share option provisions occurred mainly as a result of the accrued interest on one of the Group's ESOP derivative contracts to new loan agreements and the lapse of options relating to previous acquisitions (namely Mariposa and MSI). Restructuring provisions amounted to L79 million (September 2002: L69 million). The Group continues to implement its operational restructuring plans and recorded a total exceptional charge of L51 million in the period (including costs arising and settled in the period and a charge to provisions of L25 million). Existing restructuring provisions utilised (L13 million) and released (L3 million) were partially offset by the creation of new provisions, leading to the L10 million net increase in restructuring provisions during the quarter. The balance included provisions for warranty and contract losses, industrial injury claims, supplier obligations, provisions related to previous disposals and deferred tax provisions. LIQUIDITY AND CAPITAL RESOURCES NET DEBT Group net debt amounted to L2,819 million at 31 December 2002 compared to L2,846 million at 30 September 2002. The decrease of L27 million achieved during the third quarter resulted from the Group's total cash inflow before use of liquid resources and financing of L29 million. A favourable foreign exchange translation gain of L28 million was offset by a L30 million non-cash reduction in net debt relating to the termination of interest rate and equity swap arrangements converted to new loan agreements during the period. The following table sets forth the composition of the Group's net debt at 31 December 2002 and 30 September 2002: <Table> <Caption> 31.12.02 30.09.02 -------- -------- <S> <C> <C> Euro and US$ Bond Debt 1,699 1,695 Syndicate Bank Debt(1) 2,114 2,117 Bilateral and Other Bank Debt 91 105 Gross Financial Indebtedness 3,904 3,917 Cash(2) 1,085 1,071 ----- ----- Net Financial Indebtedness 2,819 2,846 ===== ===== </Table> --------------- 1. including L30 million relating to the termination of interest swap and equity derivative arrangements during the quarter and L54 million relating to the conversion of interest swap arrangements to new loan agreements during the first half. At 31 December 2002, the Group had a total restricted cash balance, defined as cash pledged or advanced as collateral, of L868 million. Of this, L701 million reflected the cash in the secured accounts described above, L107 million reflected cash collateral placed against bonding facilities; L17 million reflected cash in the Group's captive insurance company and L16 million reflected cash deposited against secured loans in Italy. In addition, L27 million has been placed in an escrow account pending determination of certain claims of the Group's ESOP Derivative Banks in respect of certain previously disposed companies (see "Share Price Risk" for further information). 2. Of the Group's L217 million unrestricted cash held outside of the secured accounts as at 31 December 2002, L110 million was a combination of cash in transit and global working capital balances held at subsidiary level or within the Group's joint ventures with the remaining L107 million held in money market deposits in the Group's Treasury centres. The Group has not taken into account the impact of its proposed Restructuring when reporting its financial indebtedness position. 551

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- CASH FLOW FOR THE THREE MONTHS ENDED 31 DECEMBER 2002 The Group generated a net cash inflow of L29 million before use of liquid resources and financing during the third quarter. This was driven by a net cash inflow from operating activities before capital expenditure and exceptional items of L72 million partially offset by net exceptional and non-operating cash outflows of L43 million. During the third quarter, the Group benefited from the receipt of a tax repayment and the lower level of net interest paid in the context of the financial restructuring (see Returns on Investments and Servicing of Finance below), which partially offset the exceptional cash costs relating to the Group's ongoing operating and financial restructuring processes. Operating Cash Flow The Group operating loss before exceptional items of L77 million offset by depreciation and amortisation of L56 million and a L93 million reduction in working capital led to the Group's operating cash inflow of L72 million during the period. After a L3 million inflow from net capital expenditure (including proceeds of fixed asset disposals), the Group adjusted operating cash inflow was L75 million. This was a marked improvement on the adjusted operating cash outflows recorded during the previous quarters of the year (Q1 2003: L99 million; Q2 2003: L68 million) and was driven mainly by the reduced operating losses and improved working capital contributions, particularly in the Core business where adjusted operating cash flow improved from an outflow of L81 million and L43 million in the first and second quarters respectively to an inflow of L66 million in the third quarter. The overall reduction in working capital during the third quarter was largely driven by cash collections from debtors relating to sales in prior periods when trading volumes were higher than current levels as well as the utilisation of inventory, partially offset by a reduction in creditors. Capital Expenditure and Financial Investment Gross capital expenditure amounted to L7 million during the period and related primarily to the Core business (L6 million). The Group has maintained capital expenditure well below the level of depreciation, which amounted to L28 million, of which L26 million related to the Core. Core capital expenditure is generally focused on development models, test equipment, sales demonstration equipment and R&D laboratory equipment. During the third quarter, almost L4 million of Core capital expenditure was incurred in Optical Networks and BBRS while a further L1 million was spent in North American Access in relation to the purchase of assets from Jabil as part of the transfer of one of the US facilities to a lower cost location. The disposal of property and other tangible fixed assets contributed a L9 million cash inflow during the period. Returns on Investments and Servicing of Finance Net interest paid during the period amounted to L11 million, comprising interest paid of L18 million relating mainly to the payment of interest accrued on the Group's syndicate bank and bond debt, partially offset by interest received on the Group's cash balance and in relation to the receipt of a tax repayment during the quarter (L7 million). As part of the proposed restructuring, L435 million is to be distributed to the relevant scheme creditors, of which L95 million represents the payment of due and accrued interest already made on Corp's financial debt. Of this L95 million, L78 million was paid during the first half of the financial year and L17 million was paid during the third quarter. The Group continues to accrue interest on Corp's financial debt and this is reflected in the Group's Profit and Loss account but no further cash payments have been made in this respect since the payment of interest accrued as at 15 October 2002. As disclosed in the Group's Financial Restructuring announcement dated 18 March 2003, in common with Corp's and plc's approach to other scheme claims, pending the outcome of the schemes of arrangement, neither Corp nor plc intends to make payment in respect of its obligations under its syndicate bank or bond debt due during March 2003, in full or in part. Accrued but unpaid interest of Corp and plc at the record date for the schemes of arrangement will form part of the scheme claims. 552

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Exceptional Cash Flows The Group incurred operating exceptional cash costs of L82 million during the third quarter. Over half of this amount related to the direct cash cost of severance payments and site rationalisation and closures in the context of the Group's operational restructuring and reorganisation. The balance relates mainly to the payment of fees and expenses to advisors in the context of the Group's financial restructuring and to cash costs associated with the Group's manufacturing outsourcing programme. Cash Flows from Acquisitions and Disposals Net proceeds from acquisitions and disposals led to a cash inflow of approximately L2 million during the third quarter. This related mainly to the disposal of the Group's legacy South African operations. Tax The Group received a net tax repayment of approximately L45 million during the third quarter relating to the repayment of advanced corporation tax in the United Kingdom on foreign income dividends from previous years. SYNDICATE BANK AND BOND DEBT At 31 December 2002, drawings under the Group's remaining Syndicated Facility amounted to an equivalent of L2,033 million, comprising of actual drawings of L650 million and US$2,226 million. At 31 December 2002, Corp had Yankee Bonds outstanding with principal US$1,539 million (L956 million) and Eurobonds outstanding with principal E1,175 million (L766 million). CUSTOMER FINANCING COMMITMENTS The Group, like its competitors, continues to experience demand for financing from its customers. However, this demand has decreased significantly due to market conditions and the Group's focus on its core base of incumbent carrier customers. When the Group has supported customer financing requests, it has significantly limited its own risk by: i) leveraging funds from third party financiers' having strategic interests aligned with the Group, and ii) developing innovative commercial alternatives that do not involve long-term cash investments from the Group. Through these actions, the Group has satisfactorily accommodated most customer financing requests and will not require Group cash resources to fund these activities in the foreseeable future. As at 31 December 2002, the Group had vendor finance commitments of approximately L46 million of which L39 million had been drawn. The reduction compared to commitments of L68 million at 30 September 2002 was primarily due to the resolution of two of the Group's outstanding positions. In addition, the Group uses export credit agencies to assist in managing political and credit risks on major contracts and makes extensive use of export credit insurance in respect of small to medium-sized contracts. Some customers in the telecommunications market require that bank bonds or surety bonds (those issued by insurance companies) are provided to guarantee performance of the supplier. Group companies had L213 million of such bonds outstanding as at 31 December 2002 with both banks and insurance companies world-wide (30 September 2002: L221 million). Some of these bonds are covered by counter-indemnities from Corp and others have counter-indemnities from other Group companies. The Group's bonding is normally provided on an uncommitted basis. As a consequence of the Group's ongoing financial restructuring, all new bonds currently have to be fully cash collateralised. Since February 2002, Marconi Bonding Limited (a special purpose vehicle used for this purpose) has procured the issue of approximately L107 million of performance bonding (on a fully cash collateralised basis) on behalf of other Group companies. 553

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- A maturity profile of all bonds and guarantees outstanding at 31 December 2002 is set out below: <Table> <Caption> 31.12.02 30.09.02 IN L MILLION ------------ ------------ <S> <C> <C> YEAR ENDING 31 MARCH, 2003 or earlier 29 48 2004 37 31 2005 16 13 2006 60 49 2007 35 27 Thereafter 8 6 No expiry date 28 47 ------------ ------------ Total 213 221 ============ ============ </Table> A number of the Group's performance bond arrangements carry rights for the issuer to call for cash collateral, either unconditionally or upon the occurrence of certain events. The Group estimates that as at 31 December 2002, performance bonds with a face value of approximately L70 million have varying conditional or unconditional rights to call for cash collateral. Bonds will frequently run beyond the contracted maturity dates indicated in the table above. In addition, there are a number of bonds with no expiry date. These may be cancelled by the beneficiaries when the guaranteed works are completed. RISK MANAGEMENT The main risks faced by the Group in the financial markets are liquidity risk, interest rate risk, foreign exchange risk and share price risk. LIQUIDITY RISK The Group has funded its liquidity requirements mainly through a combination of internally generated funds, bank borrowings, debt issues in the capital markets and the disposal of non-core businesses. The Group is currently unable to arrange any new lending facility or to raise new funds through the issuance of debt or equity securities. Consequently, the Group has little or no ability to obtain new external funding and does not expect to have such ability unless and until the proposed Restructuring is complete. As previously disclosed, the majority of the Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the Group's Syndicate Banks and bondholders (including the bond trustees) and also to Barclays, as the sole ESOP Derivative Bank who, prior to 15 October 2002, committed to support the proposed Restructuring. The secured accounts were created at the end of April 2002 in accordance with the previously disclosed lock box arrangements entered into in favour of the Group's Syndicate Banks and bondholders. The interim security arrangements contemplated by the Heads of Terms were implemented on 13 September 2002 and were amended on 13 December 2002. As at 13 September 2002, the balance of the secured accounts was approximately L866 million. At 31 December 2002, the balance of this secured cash amounted to L701 million. The Group is dependent on amounts available to it from the secured amounts in order to meet its short-term liquidity needs. The interim security arrangements described above are not affected by the ESOP settlement referred to below. Prior to the release of interim security and so long as an enforcement event does not occur, monthly releases from the secured accounts are approved in accordance with an agreed cash flow schedule, subject to specified maximum amounts. This agreed cash flow schedule is consistent with the Group's expectations as to its liquidity needs for the relevant period. The schedule, covering the period to the end of June 2003 is expected to be approved by the Group's Syndicate Banks and the ad hoc committee of bondholders in connection with the request for an extension of the timetable for the Restructuring referred to below. The interim security is subject to various enforcement events, some of which are tied to the prospects of successfully completing the Restructuring in accordance with the non-binding indicative heads of terms (and within the agreed timetable, which is currently 15 March 2003). The occurrence of an enforcement event would entitle the requisite majority of creditors to block withdrawals from the secured accounts and/or enforce the 554

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- interim security. As at the present date a request has been made to the Group's Syndicate Banks and Ad Hoc Committee of Bondholders for an extension of the timetable for completion of the Restructuring (to 19 May 2003) and plc and Corp are confident that this extension will be granted. INTEREST RATE RISK It has in the past been Group policy to maintain at least 50% of debt at fixed rates of interest. The term structure of interest rates was managed in observance of this policy using derivative financial instruments such as interest rate swaps. However, due to the Restructuring process described above, this has been superceded by the requirement to manage immediate liquidity, which involved the cancellation of all outstanding interest-related derivatives positions. Consequently, in the nine months to 31 December 2002, all the Group's out-of-the-money interest rate swap arrangements were converted to new loan agreements. At 31 December 2002, 44 per cent of the Group's interest-bearing borrowings were at fixed rates after taking account of interest rate swaps. Of this total, 24 per cent were at fixed dollar rates of interest and 20 per cent were at fixed euro rates of interest. In the three months ended 31 December 2002, the average interest rate received on cash and liquid investments was approximately 2.25 per cent per annum, and 100 per cent of deposits were at floating rates. The largest proportion of investments was in US dollar deposits -- the Group held an average of approximately $770 million in US dollar deposits, earning an average interest rate of approximately 1.5 per cent per annum. These US dollar deposits match in part the US dollar borrowings referred to under Syndicate Bank and Bond Debt above. FOREIGN EXCHANGE RISK The Group conducts a significant portion of its business activities outside the United Kingdom in currencies other than sterling. The Group's principal exchange rate exposures relate to U.S. dollar/pounds sterling and euro/pounds sterling exchange rates for both transactional and translation related exposures. As a matter of general policy, the Group enters into foreign currency forward exchange contracts in the ordinary course of business to protect itself from adverse currency rate fluctuations on firm contracts where cash receipts or payments are in a foreign currency different from that of the Group business which is contracting with customers or suppliers. These contracts are executed with creditworthy banks. The Group has little or no ability to enter into such contracts at present and does not expect to have such ability unless and until the proposed Restructuring is complete. The Group also has overseas subsidiaries that incur losses/earn profits and whose net liabilities or net assets are denominated in foreign currencies. It is not the Group's policy to use derivatives to hedge exposures arising from the translation of these overseas losses/profits and net liabilities/assets into pounds sterling. However, approximately 82 per cent of gross borrowings were denominated in foreign currencies in order to form a hedge for investments in currencies other than sterling. Of these, 62 per cent, denominated in U.S. dollars, formed a hedge for the Group's investment in the United States, and 20 per cent, denominated in euro, formed a hedge for the Group's investment in the euro zone. If the pound had strengthened such that the average exchange rates used in the translation of the Group's overseas earnings changed by 10 per cent, our reported loss from continuing operations would have been reduced by 7.1 per cent, in the nine months ended 31 December 2002. SHARE PRICE RISK The Group has, in the past, issued share options to its employees under a number of different option plans, collectively known as the Employee Share Option Plans ("ESOP"). Under these plans, options may be satisfied by way of a transfer of existing plc ordinary shares acquired in the market by an employee trust or other vehicle, or, under some of the plans only, by an issue of new plc shares. As previously disclosed, during the first half of calendar year 2000, in order to hedge part of the potential cost of the plans estimated at that time, the Marconi Employee Trust entered into contracts with three banks (the "ESOP Derivative Banks") to purchase a total of 40 million shares in the future at prices which were fixed at the date of contract, of which as at 6 December 2002, 38.5 million remained outstanding. The equity derivative with UBS which related to 10 million shares was consensually closed out on 6 December 2002. The Group's maximum 555

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- exposure under the equity derivative contracts (including the closed out UBS equity derivative) is L337 million, plus accrued finance charges. This level of exposure had accrued as at 31 December 2002. For every 10 per cent movement in the share price, the change in the fair value of the ongoing contracts is immaterial. One of the equity derivative contracts requires (and, before its termination, the UBS equity derivative required) the Marconi Employee Trust to deposit cash collateral with the respective Derivative Banks if the share price falls to certain levels stipulated in the contracts. Corp has, in the past, funded the provision of this collateral. Prior to the close out of the UBS equity derivative (and as at 31 December 2002), L214 million of collateral, the maximum amount of collateral payable under these contracts, had been paid. No further collateral will become due. Due to the substantial deterioration in the Group's share price, only limited amounts of options with zero exercise price have been or are likely to be exercised. The uncollateralised exposure under the ESOP derivative contracts (including the closed out UBS equity derivative) as at 31 December 2002 is comprised of principal of L123 million, together with accrued finance charges of L46 million. As previously announced, up to L145 million (not including the previously announced L25 million Strategic Communications escrow which benefited all of the ESOP Derivative Banks) was to be set aside into escrow, on the effective date of the Corp Scheme, pending determination of potential liabilities of Group companies to participating ESOP Derivative Banks (those who had undertaken to support the Restructuring) in relation to the ESOP derivative transactions. Only Barclays Bank PLC ("Barclays") elected to participate in these arrangements and on 13 September 2002, Barclays, plc and Corp entered into a restructuring undertaking agreement under which Barclays undertook, subject to certain termination events, to vote in favour of the Restructuring. On 13 December 2002, a definitive agreement setting out the terms of that proposed escrow arrangement was entered into between, inter alia, plc, Corp and Barclays. The terms of this escrow which would have applied on the effective date of the Restructuring have now been superseded somewhat by the ESOP settlement agreement referred to below. Corp and plc have reached agreement with the Group's ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group (subject to obtaining any requisite creditor consents). Under the terms of the settlement, which is conditional upon the Corp scheme of arrangement becoming effective, Corp will pay a total of L35 million (the "Settlement Amount") to the ESOP Derivative Banks in full and final settlement of their ESOP related claims against the Group. The Settlement Amount will be paid from the fund of up to L170 million (including the Strategic Communications escrow) which was to have been set aside by Corp, as part of the Restructuring, pending resolution of potential liabilities of Group companies to participating ESOP Derivative Banks in relation to the ESOP derivative transactions. The settlement has made available approximately L135 million in cash which will now form part of the L340 million initial cash distribution referred to above (in return for a L123 million reduction in the face value of the New Junior Notes to be issued as part of the Restructuring i.e. equivalent to redemption at 110 per cent of face value). Without the ESOP settlement, the L135 million sum would not have formed part of the initial cash distribution. INSURANCE RISK MANAGEMENT The Group manages centrally the purchase of global insurance policies in respect of major insurable risks, including property (material damage/business interruption), directors' and officers and public and products liability. The use of global policies and centrally appointed brokers allows the Group to improve internal control and optimise the overall level of retained risk. Risk management and insurance expenditure are concentrated on those insurable risks which are considered potentially catastrophic to the Group as a whole. The Group continues to work with its insurers and advisers to improve its loss prevention and mitigation processes. Insurance market conditions are currently very challenging and premium rates have increased substantially. However, the Group benefits from good relationships with its major insurers. 556

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- NOTES 1 FUNDAMENTAL UNCERTAINTY IN RESPECT OF THE APPLICATION OF THE GOING CONCERN BASIS Corp owes approximately L2.1 billion under a syndicated credit facility (the "Bank Facility") which was due for repayment on 25 March 2003. Borrowings under the facility are repayable on demand and no further funds may be drawn under its terms. The Group also has in issue Eurobonds and Yankee Bonds (the "Bonds") with a face value of L1.7 billion. plc guarantees Corp's debt obligations under the Bonds and the Bank Facility. As at 31 December 2002, net debt of the Group stood at approximately L2.8 billion. On 29 August 2002, plc announced that non-binding indicative Heads of Terms, which set out the principles for the financial restructuring of plc and Corp (the "Restructuring"), had been concluded with the co-ordination committee of syndicate banks and an informal ad hoc committee of Bondholders. On 16 December 2002 plc announced that modifications to the non-binding indicative Heads of Terms had been concluded. The non-binding indicative Heads of Terms envisage that the creditors of plc and Corp, other than certain excluded creditors, will be subject to schemes of arrangement ("Schemes") under which creditor claims will be compromised in consideration for cash, new equity and new debt securities of Corp. As part of the restructuring Corp will become the listed parent for the Group and, following completion of its Scheme, it is currently anticipated that plc will be dissolved. The Restructuring will leave existing plc shareholders with 0.5% of the equity in Corp. On 17 March 2003, documentation for the proposed Schemes was filed with the High Court of England and Wales, initiating the final steps towards implementation of the Restructuring. The non-binding indicative Heads of Terms envisage a new capital structure for the Group that is appropriate to the latest business plan developed by the Group. The implementation of this capital structure involves, among other things, the payment of L320 million of cash (in addition to L95 million accrued interest on Corp's financial debt, paid in September and October 2002), the issue of new equity and the issue of new notes with a face value, using 31 December 2002 exchange rates, of approximately L763 million by Corp to its schemed creditors through the operation of the Schemes. As part of the arrangements to implement the Restructuring, the majority of the Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the Group's Syndicate Banks and Bondholders (including the Bond trustees, but excluding Ancrane, a subsidiary of plc which holds Bonds) and also to one of the Group's ESOP Derivative Banks (who committed to support the proposed Restructuring within the required time period). At 31 December 2002, the balance of this secured cash amounted to L701 million. The Group is dependent on amounts available to it from the secured amounts in order to meet its short-term liquidity needs. Prior to the release of interim security and so long as an enforcement event does not occur, monthly releases from the secured accounts are approved in accordance with an agreed cash flow schedule, subject to specified maximum amounts. This agreed cash flow schedule is consistent with the Group's expectations as to its liquidity needs for the relevant period. The current agreed cash flow schedule covers the period to the end of March 2003. A revised schedule, covering the period to the end of June 2003 is expected to be approved by the Group's Syndicate Banks and the Ad Hoc Committee of Bondholders in connection with the request for an extension of the timetable for the Restructuring referred to below. When the non-binding indicative Heads of Terms were announced on 29 August 2002, the Group indicated that the Restructuring was scheduled to be completed by 31 January 2003 (the "Effective Date"). This date was extended to 15 March 2003 in December 2002. As a result of the complexity of the Restructuring the Effective Date of the Schemes is now expected to be on or around 19 May 2003. The change to the timing of the Restructuring introduces risks associated with certain financial debt falling due in March 2003. In particular, as noted above, the Bank Facility was due for repayment on 25 March 2003 and interest payments were due on the Yankee Bonds on 17 March 2003 and are due on the Eurobonds on 31 March 2003. Failure to repay the Bank Facility, either on demand or on 25 March 2003, gives rise to direct rights on the part of individual syndicate banks to bring actions for recovery of the debt owing to them and, in addition, after the expiry of a five business day grace period, result in a cross default under the Bonds. In common with the Group's approach to other 557

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Scheme claims, pending the outcome of the Schemes, the Group does not intend to make payment in respect of such obligations, in full or in part. The fact of the aforementioned payments falling due represents a risk to the Restructuring, due to consequential legal action which Syndicate Banks or Bondholders who are not supportive of the Restructuring process could take against Corp or plc. However, Corp and plc are of the view that, given the timing associated with any such legal action as well as the likely attitude of the English and New York Courts to a creditor seeking to frustrate the Restructuring (which is intended to be for the benefit of all Scheme creditors), these risks should be manageable. The interim security is subject to various enforcement events, some of which are tied to the prospects of successfully completing the restructuring in accordance with the non-binding indicative Heads of Terms (and within the agreed timetable, which is currently, as mentioned above, 15 March 2003). The occurrence of an enforcement event entitles the requisite majority of creditors to block withdrawals from the secured accounts and/or enforce the interim security. At the present date, following the delays to the timing of the Restructuring described above, an unwaived enforcement event is continuing, although no enforcement action has been taken. Corp's request for a waiver of this enforcement event is due to be considered by the Group's syndicate banks on 19 March 2003 and by the ad hoc committee of bondholders prior to posting of the Scheme document to Scheme creditors. Corp and plc are confident that a waiver will be granted. The Restructuring of plc is dependent on approval of the Corp and plc Schemes. Approval of these Schemes will be dependent on, amongst other things, securing the necessary level of support of the Syndicate Banks, Bondholders and other creditors whose claims will be compromised, in the relevant creditors' meetings to be held as part of the Scheme process, as well as the approval of the English court and the granting of a permanent restraining order by the U.S. Bankruptcy Court. Letters of current intention to support the Restructuring and to vote for the plc and Corp Schemes were obtained from the joint lead coordinators of the Group's Syndicate Banks and from each of the members of the Ad Hoc Bondholder Committee in December 2002. Neither plc nor Corp has received any notice of any changes to this intention. In the light of the information currently available to them, Corp and plc believe that the Group's bankers, Bondholders and other creditors will support the Restructuring and that all the conditions for the Restructuring will be satisfied. On this basis, plc considers it appropriate to prepare the accounts on the going concern basis. Should the Group's Syndicate Banks, Bondholders and other creditors cease to support the Group before the completion of the Restructuring, or should all of the conditions for the Restructuring not be met, there would be no realistic alternative for Corp and plc but to commence insolvency proceedings and the going concern basis of preparation would no longer be applicable; adjustments would be necessary to record additional liabilities and to write down assets to their recoverable amount. It is not practicable to quantify these possible adjustments. 2 ACCOUNTING POLICIES The more important Group accounting policies are summarised below to facilitate the interpretation of the non-statutory financial statements. As disclosed in the 2002 Annual Report and Accounts, the Group accounts for pension costs and retirement benefits in accordance with FRS 17. This requires an annual actuarial assessment of the defined benefit pension schemes, which is carried out by the Group's independent actuarial advisers. The Group carried out a further actuarial assessment for the six month period ended 30 September 2002. ACCOUNTING CONVENTION The non-statutory financial statements are prepared under the historical cost convention, as modified by the valuation of listed current and fixed asset investments. 558

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- BASIS OF CONSOLIDATION The non-statutory financial statements consolidate the accounts of plc and all of its subsidiary undertakings (Group companies or subsidiaries). All inter-company balances and transactions have been eliminated upon consolidation. All Group companies' results and cashflows have been prepared for the three months ended 31 December 2002 and 31 December 2001 with consolidated group balance sheets at 31 December 2002 and 30 September 2002. Consequently, comparative information has not been provided for the consolidated statement of recognised gains and losses and reconciliation of movements in equity shareholders' interests. TURNOVER Turnover, excluding VAT, comprises sales to outside customers, and the Group's percentage interest in sales by their joint ventures. The Group records transactions as sales when the delivery of products or performance of services takes place in accordance with the terms of sale. Turnover on long term contracts is calculated as a proportion of the total contract value based on the ratio of costs incurred to date compared with the total expected costs for that contract. CURRENCY TRANSLATION Transactions denominated in foreign currencies are translated into the functional currency at the rates ruling at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are retranslated at the rates ruling at that date. These translation differences are dealt with in the profit and loss account with the exception of certain gains and losses arising under hedging transactions as described below. Profits and losses of overseas subsidiaries, joint ventures and associates and cash flows of overseas subsidiaries are translated at the average rates of exchange during the period. Non-sterling net assets are translated at period end rates of exchange. Key rates used are as follows: <Table> <Caption> Average rates Period-end rates ---------------------------------------- ---------------------------------------- 31 DECEMBER 30 September 31 December 31 DECEMBER 30 September 31 December 2002 2002 2001 2002 2002 2001 ----------- ------------ ----------- ----------- ------------ ----------- <S> <C> <C> <C> <C> <C> <C> US dollar 1.5389 1.5204 1.4359 1.6098 1.5726 1.4554 Euro 1.5739 1.5813 1.6239 1.5342 1.5913 1.6346 =========== ============ =========== =========== ============ =========== </Table> The differences arising from the restatement of profits and losses and the retranslation of the opening net assets/(liabilities) to period end rates are taken to reserves. ACQUISITIONS AND DISPOSALS On the acquisition of a business, including an interest in an associated undertaking, fair values are attributed to the group's share of separable net assets. Where the cost of acquisition exceeds the fair values attributable to such net assets, the difference is treated as purchased goodwill and capitalised in the balance sheet in the year of acquisition. The profit or loss on the disposal or closure of a previously acquired business includes the attributable amount of any purchased goodwill relating to that business not previously charged to the profit and loss account. The results and cashflows relating to a business are included in the consolidated profit and loss account and the consolidated cash flow statement from the date of acquisition or up to the date of disposal. 559

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- FINANCIAL INSTRUMENTS The Group uses financial instruments, including interest rate swaps, currency swaps and other derivatives, solely for the purposes of raising finance for its operations and managing interest and currency risk associated with the Group's underlying business activities. There is no trading activity in financial instruments. FORWARD FOREIGN EXCHANGE CONTRACTS Forward foreign exchange contracts generally exhibit a high correlation to the hedged items and are designated and considered effective as hedges of the underlying assets, liabilities and firm commitments. Gains and losses on forward foreign exchange contracts which are designated as hedges of assets, liabilities and firm commitments of the group are recognised in the profit and loss account or as adjustments to carrying amounts when the hedged transactions occurs. HEDGES OF THE NET INVESTMENT IN OVERSEAS SUBSIDIARIES The Group's policy has been to finance its activities in the same currencies as those used for its foreign investments in order to hedge foreign currency exposure of net investments in foreign operations. This policy is implemented either by financing in the related currency or using derivatives, such as currency swaps, which provide a synthetic effect of a foreign currency loan, thereby reducing the exchange risk. Exchange gains or losses arising on the hedging borrowings and on the notional principal of currency swaps during their life and at termination or maturity, together with the tax thereon, are dealt with as a movement in reserves, to the extent they offset losses or gains on the hedged investment. In respect of hedges of net investments, the Group enters into tax equalisation swaps, the gains and losses of which are recognised through the statement of total recognised gains and losses (in accordance with the underlying transaction and the tax thereon) with any forward premium or discount recognised over the life of the contract in the profit and loss account. EQUITY FORWARD CONTRACTS The Group has established three trusts for the purchase of shares and share-related instruments for the benefit of employees -- the Marconi Employee Trust (MET), the GEC Employee Share Trust and the GEC Special Purpose Trust. These trusts are consolidated in the financial statements of the Group. The independent trustee of the MET, Bedell Cristin Trustees Limited ("BCT") has entered into contracts (the Equity Forward Contracts) to hedge the potential cost of the Group's share plans. On or before maturity of the Equity Forward Contracts, the MET may either take delivery of plc shares at the contracted purchase price (including accrued interest) or may cash settle the contracts for a net amount based on the difference between the plc share price and the contract purchase price (including accrued interest). The obligation to settle the contracts including accrued interest is classified as a provision within the Group's balance sheet. This liability is calculated by taking the shares under contract and applying the difference between plc's share price and the contract purchase price per share, adjusted for brokerage costs, on a contract-by-contract basis. No cash is exchanged until the maturity of the contract (or earlier upon either option exercises by employees or cash settlement of the contracts at the MET's option) unless collateral is required. Where the MET has provided collateral this has been offset against the provision in the consolidated balance sheet. Interest costs on the equity notional are calculated as LIBOR plus a margin less dividends, if any, and are accrued on a monthly basis, with a debit to interest and a credit to provisions. INTEREST RATE RISK EXPOSURE The Group hedges its exposure to movements in interest rates associated with its borrowing primarily by means of interest rate swaps and forward rate agreements. Payments and receipts under interest rate swap agreements specifically designated for hedging purposes are recorded in the profit and loss account on an accruals basis. 560

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Gains and losses arising on termination of hedging instruments where the underlying exposure remains are recognised in the profit and loss account over the remaining life of the underlying exposure. TANGIBLE FIXED ASSETS Property, plant, machinery, fixtures, fittings, tools and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives from the time they are brought into use. Freehold land does not bear depreciation where the original cost of purchase was separately identified. Provision is made for any impairment. Tangible fixed assets are depreciated using the following rates: <Table> <S> <C> Freehold buildings -- 2 per cent to 4 per cent per annum Leasehold property -- over the period of the lease or 50 years for long leases Plant and machinery -- 10 per cent per annum on average Fixtures, fittings, tools and equipment -- 10 per cent per annum </Table> LEASED ASSETS Assets held under finance lease and other similar contracts, which confer rights and obligations similar to those attached to owned asset, are capitalised as tangible fixed assets and are depreciated over the shorter of the lease terms and their useful lives. The capital elements of future lease obligations are recorded as liabilities, while the interest elements are charged to the profit and loss account over the period of the leases to produce a constant rate of charge on the balance of the capital repayments outstanding. Hire purchase transactions are dealt with similarly except that assets are depreciated over their useful lives. Rentals under operating leases are charged on a straight-line basis over the lease term, even if the payments are not made on such a basis. GOODWILL Purchased goodwill is capitalised and amortised on a straight-line basis over its estimated useful economic life. Each acquisition is separately evaluated for the purposes of determining the useful economic life, up to a maximum of 20 years. The useful economic lives are reviewed annually and revised if necessary. Provision is made for any impairment. RESEARCH AND DEVELOPMENT Expenditure incurred in the period is charged against profit unless specifically chargeable to and receivable from customers under agreed contract terms. STOCK Stock is stated at the lower of cost and net realisable value. Provision is made for obsolete, slow-moving or defective items where appropriate. CONTRACTS IN PROGRESS Profit on long-term contracts in progress is taken when a sale is recorded on part-delivery of products or part-performance of services, provided that the outcome of the contract can be assessed with reasonable certainty. Amounts recoverable on long-term contracts, which are included in debtors, are stated at the net sales value of the work done less amounts received as progress payments on account. Excess progress payments are included in creditors as payments received in advance. Cumulative costs incurred net of amounts transferred to cost of sales, less provision for contingencies and anticipated future losses on contracts, are included as long-term contract balances in stock. 561

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- WARRANTIES Provisions for estimated expenses related to product warranties are made at the time products are sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims. TAXATION Taxation on profit on ordinary activities is that which has been paid or becomes payable in respect of the profits for the year. Deferred taxation is provided in full on timing differences that result in an obligation at the balance sheet date to pay more tax, or a right to pay less tax, at a future date, at rates expected to apply when they crystallise based on current tax rates and law. Timing differences arise from the inclusion of items of income or expenditure in taxation computations in periods different from those in which they are included in the financial statements. Deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered. Deferred tax assets and liabilities are not discounted. INVESTMENTS Joint ventures comprise long-term investments where control is shared under a contractual arrangement. The sector analysis of turnover, profit and net assets includes the Group's share of the results and net assets of joint ventures. Associates consist of long-term investments in which the Group holds a participating interest and over which it exercises significant influence. Investments in joint ventures and associates are stated at the amount of the Group's share of net assets including goodwill at 31 December 2002 derived from audited or management accounts made up to that date, other than Easynet Group Plc whose results for the six months to 31 December 2002 have been prorated to provide a three months movement. Loss before taxation includes the Group's share of joint ventures and associates. Other unlisted fixed asset investments are stated at cost less provision for impairment in value. Listed fixed asset investments are stated at market value. Current asset investments are stated at the lower of cost and net realisable value except dated listed securities which are stated at market value. Investments in plc's shares, held within the GEC Employee Share Trust and the Marconi Employee Trust, are included on the Group balance sheet at cost, less provision for impairment. PENSIONS AND OTHER POST RETIREMENT BENEFITS The operating cost of providing pensions and other post retirement benefits, as calculated periodically by independent actuaries, is charged to the Group's operating profit or loss in the period that those benefits are earned by employees. The financial return expected on the schemes' assets is recognised in the period in which they arise as part of finance income and the effect of the unwinding of the discounted value of the schemes liabilities is treated as part of finance costs. The changes in value of the schemes' assets and liabilities are reported as actuarial gains or losses as they arise in the consolidated statement of total recognised gains and losses. The pension schemes' surpluses, to the extent they are considered recoverable, or deficits are recognised in full and presented in the balance sheet net of any related deferred tax. In the three months ended 31 December 2002 the Group has charged the profit and loss account with L6 million of service cost and L2 million of notional interest in respect of defined benefit schemes on the basis of the 30 September 2002 actuarial assessment. This will be updated during the final quarter of the year ending 31 March 2003, and any actuarial gains and losses arising on pension assets and liabilities in the balance sheet will be shown in the statement of total recognised gains and losses for the year ending 31 March 2003. SHARE OPTIONS The costs of awarding shares under employee share plans are charged to the profit and loss account over the period to which the performance criteria relate. When share options granted lapse, any associated costs that were 562

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- treated as cost of acquisition are credited to either goodwill, or to the profit and loss account if there is no remaining goodwill. FINANCE COSTS Finance costs of debt are recognised in the profit and loss account over the term of such instruments at a constant rate on the carrying amount. DEBT Debt is initially stated at the amount of the net proceeds after deduction of issue costs. The carrying amount is increased by the finance cost in respect of the accounting period and reduced by payments made in the period. LIQUID RESOURCES Liquid resources comprise term deposits with an original maturity of generally less than one year and other readily disposable current asset investments. 3 PRINCIPAL ACTIVITIES, (LOSS)/PROFIT CONTRIBUTIONS, MARKETS AND NET ASSETS/(LIABILITIES) EMPLOYED ANALYSIS OF RESULTS AND NET ASSETS/(LIABILITIES) BY CLASS OF BUSINESS <Table> <Caption> Net assets/ (Loss)/profit Turnover (liabilities) --------------------------- --------------------------- --------------------------- 3 MONTHS TO 3 Months to 3 MONTHS TO 3 Months to 31 DECEMBER 31 December 31 DECEMBER 31 December 31 DECEMBER 30 September 2002 2001 2002 2001 2002 2002 L MILLION L million L MILLION L million L MILLION L million ------------ ------------ ------------ ------------ ------------ ------------ <S> <C> <C> <C> <C> <C> <C> Network equipment (49) (80) 261 407 359 451 Network services 20 (32) 195 225 Other (including intra-activity sales) (12) (16) (2) -- 3 11 ------------ ------------ ------------ ------------ ------------ ------------ (41) (128) 454 632 362 462 Capital (10) (7) 12 116 (33) (19) ------------ ------------ ------------ ------------ ------------ ------------ Continuing operations (51) (135) 466 748 329 443 Discontinued operations -- 26 -- 293 -- -- ------------ ------------ ------------ ------------ ------------ ------------ (51) (109) 466 1,041 329 443 ------------ ------------ Goodwill and goodwill amortisation (28) (46) 638 672 Operating exceptional items (note 5a) (54) (94) ------------ ------------ (133) (249) Associates (11) (11) 57 69 ------------ ------------ Operating loss (144) (260) Non-operating exceptional items (note 5b) (10) 341 Net interest payable and interest bearing assets and liabilities (51) (66) (2,807) (2,838) Net finance income 7 61 Unallocated net liabilities (943) (889) ------------ ------------ ------------ ------------ (198) 76 (2,726) (2,543) ============ ============ ============ ============ </Table> The Group has divided its business into two segments: Core and Capital. The Group's Core businesses are the provision of optical networks, broadband routing and switching and broadband access technologies and associated installation, maintenance and other value-added services. Their customer base includes telecommunications companies, providers of Internet services for their public networks, and to certain large corporations, government departments and agencies, utilities and educational institutions for their private networks. Core activities are divided into Network equipment, Network services and Other. 563

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Capital comprises the businesses the Group manages for value and ultimately for disposal. The Group's share of joint ventures' (loss)/profit, turnover and net assets are included under Capital. Goodwill arising on acquisitions is amortised over a period not exceeding 20 years. Separate components of goodwill are identified and amortised over the appropriate useful economic life. The remaining goodwill on the balance sheet will be amortised over an average period of approximately 7 years. Comparative figures have been restated to reflect the changes in the Group structure during the period since 31 December 2001. The net assets of Network equipment and Network services cannot be separately identified as the same assets are, generally, used to generate sales in each of these segments. The results of these segments are separately reportable. Sales by Group companies to joint ventures and associates in the three months amounted to L6 million (31 December 2001 L10 million). Purchases from joint ventures and associates amounted to Lnil (31 December 2001 L4 million). Assets and liabilities arising out of the Retirement Benefit Plan are treated as unallocated net liabilities. It is not practical to disclose goodwill amortisation on a segmental basis as any allocation would be arbitrary.

This arose as a consequence of the manufacturing outsourcing arrangement with Jabil Circuits Inc whereby the Group was able to release stock provisions where the components had been utilised. In the three months ended 31 December 2001 a charge of L20 million was incurred in respect of such inventory. (ii) In the three months ended 31 December 2002 a charge of L9 million was booked for impairment of Italian fixed assets and UK and US buildings in continuing operations. (iii) As part of the Group's cost reduction actions, a charge of L51 million was recorded during the three months to 31 December 2002 associated with employee severance, site rationalisation costs and other restructuring costs (31 December 2001 L63 million). The site rationalisation costs reflect the charges associated with closing and consolidating various sites around the world as part of the business restructuring. (iv) During the year ended 31 March 2002 the Group planned to implement a new global IT system. In light of the revised trading outlook and the continued focus on cost reduction, the implementation was terminated. During the three months ended 31 December 2001 charges of L11 million were incurred in this respect. 567

C FACTORS THAT MAY AFFECT FUTURE TAX CHARGES Deferred tax assets totalling L820 million at 31 December 2002 have not been recognised in respect of operating losses and exceptional expenditure as the Group is not sufficiently certain that it will be able to recover those assets within a relatively short period of time. Included in the unrecognised deferred tax asset as at 31 December 2002 of L820 million are amounts that may be forfeited or restricted as a consequence of the planned restructuring of the Group due to the requirements of tax legislation in various jurisdictions. It is not possible at this stage to quantify the amount of unrecognised deferred tax assets that may be forfeited. 8 (LOSS)/EARNINGS PER SHARE Basic and diluted (loss)/earnings per share are calculated by reference to a weighted average of 2,792.6 million ordinary shares (31 December 2001 2,789.6 million ordinary shares) in issue during the period. The effect of share options is anti-dilutive for each period presented and has therefore been excluded from the calculation of diluted weighted average number of shares. An adjusted basic loss per share has been presented in order to highlight the underlying performance of the Group, and is calculated as set out in the table below.

The average discount rate applied to the future cash flows is 15 per cent. and is based upon a weighted average cost of capital percentage. The results of the review indicated that no further impairment charge in respect of goodwill was necessary for the three months to 31 December 2002. However, due to the significant uncertainties over the timing and extent of any recovery in the telecommunications market, the directors acknowledge that they are likely to have to continue to review their assumptions against future performance. 10 TANGIBLE FIXED ASSETS <Table> <Caption> Fixtures, Payments on Leasehold property fittings, account and Freehold --------------------- Plant and tools and assets under property Long Short machinery equipment construction Total Group L million L million L million L million L million L million L million ----- --------- --------- --------- --------- --------- ------------ --------- <S> <C> <C> <C> <C> <C> <C> <C> Cost at 1 October 2002 128 9 8 373 544 -- 1,062 Exchange rate adjustment 1 -- -- 2 1 -- 4 Additions -- -- -- 5 2 -- 7 Disposals (17) (7) -- (25) (17) -- (66) Businesses disposed -- -- -- (6) (17) -- (23) --------- --------- --------- --------- --------- ----------- --------- COST AT 31 DECEMBER 2002 112 2 8 349 513 -- 984 --------- --------- --------- --------- --------- ----------- --------- Depreciation at 1 October 2002 37 2 5 258 431 -- 733 Exchange rate adjustment -- -- -- -- (2) -- (2) Charged to profit and loss account -- -- -- 8 20 -- 28 Impairment of fixed assets -- -- -- -- 9 -- 9 Disposals (4) (1) -- (24) (17) -- (46) Businesses disposed -- -- -- (4) (14) -- (18) --------- --------- --------- --------- --------- ----------- --------- DEPRECIATION AT 31 DECEMBER 2002 33 1 5 238 427 -- 704 --------- --------- --------- --------- --------- ----------- --------- NET BOOK VALUE AT 31 DECEMBER 2002 79 1 3 111 86 -- 280 Net book value at 30 September 2002 91 7 3 115 113 -- 329 ========= ========= ========= ========= ========= =========== ========= </Table> 571

The release in the period relates mainly to the reduction of a provision held for employees of previously acquired companies whose options have lapsed. The utilisation in the period relates mainly to the conversion of accrued interest on the ESOP derivatives into borrowings. An agreement to settle the ESOP derivative is explained in note 22. Restructuring provisions mainly comprise expected costs for termination of employee contracts, costs for properties no longer occupied and onerous lease contracts. The associated outflows are generally expected to occur over the next year with vacant property costs being incurred over the next five years. Other provisions mainly comprise the expected cost of maintenance under guarantees, other work in respect of products delivered, employee related claims, environmental liabilities, other litigation and losses on contract work in progress. The associated outflows are generally expected to occur over the lives of the products and contracts which are long term in nature. 18 DISPOSALS On 4 October 2002 the Group disposed of Marconi Communications Israel Limited and on 24 December 2002 the Group disposed of ATC Pty Ltd for cash consideration totalling L3 million. 577

The total amount disclosed above represents Corp and plc's best estimate of possible unprovided exposures that may arise in respect of these legal claims and the guarantees and bonds. 22 POST BALANCE SHEET EVENTS On 7 February 2003 the Group announced that it had agreed in principle with Barclays Bank PLC, Salomon Brothers International Limited and UBS AG to settle potential claims under ESOP derivative arrangements. This settlement is conditional upon the Corp Scheme of Arrangement becoming effective. At this point, all claims against plc, Corp and its subsidiaries in respect of this matter will be waived and the total liabilities recorded within liability provisions and net debt of L169 million will be released for a consideration of L35 million. On 24 February 2003, plc announced that, following approval from the High Court in the United Kingdom, Corp had completed a return of capital from Ultramast Limited (a joint venture company set up in December 2000 with Railtrack Telecom Services Limited) and settled all outstanding litigation relating to it. As a result of the transaction, plc received net cash proceeds of approximately L41 million. 581

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- PART B UPDATED FINANCIAL INFORMATION As previously disclosed in the 16 December 2002 announcement, in order to facilitate the Restructuring discussions, certain non-public information (the "Information") has been presented to the Syndicate Banks and certain bondholders. Prior to the presentation of the Information, Corp and plc entered into non-disclosure agreements with certain of the bondholders which required Corp and plc to publish the Information on a specified date and which restricted such bondholders from dealing in Corp and plc securities until the publication of the Information. In order to facilitate this announcement, Corp and plc agreed to publish such Information at the conclusion of these discussions. The Information contained in this Part B of this Appendix has been prepared based on certain assumptions and projections with respect to the Group's revenue generating capability, capital expenditures and operating expenses and trading conditions in the telecommunications equipment market and on the basis of information known at the time it was prepared. The Information was prepared by Group management for internal purposes and not with a view to public disclosure. The assumptions used in preparing the Information are inherently subject to significant uncertainties and actual results will differ, perhaps materially, from those projected. Neither Corp nor plc gives any assurance that the assumptions that underpin the Information are correct or that the projections and estimates contained in this Part B of this Appendix will reflect actual results of operations and cash flows. No representation is made or intended to be made with respect to the likely existence of any particular future set of facts or circumstances. No reliance should be placed on the Information or any part of it and it is not intended to persuade or incite anyone to engage in investment activity. Neither Corp nor plc will be publishing any updates in relation to any part of the Information. Corp and plc are providing the following statement by way of general caution and in order to utilise the "Safe Harbor"provision of the US Private Securities Litigation Reform Act of 1995. Except for reported financial results or other historical information, certain statements in this press release are forward-looking statements, including, but not limited to, statements that are predictions of or indicate future events, trends, plans or objectives. Reliance should not be placed on such statements because, by their nature, they are subject to known and unknown risk and uncertainties and can be affected by other factors which are beyond the control of plc and its subsidiaries, including Corp, and may cause actual results, performance and achievements to differ materially from anticipated future results, performance and achievements expressed or implied in the forward-looking statements (and from the past results, performance and achievement). Although not exhaustive, the following factors could cause such differences: any major disruption in production at the Group's or its strategic suppliers' key facilities; changes in tax, environmental and other laws and regulations, which, among other things, could cause the Group to incur substantial additional capital expenditures and operation and maintenance costs; and adverse changes in the markets for the Group's products. These factors and other factors that could affect these forward-looking statements, whether to reflect new information or future events or circumstances or otherwise. ILLUSTRATIVE FISCAL 2005 ANALYSIS The Group's Sensitised Business Plan, as published on 29 August 2002 and 16 December 2002, has been refined as part of the Group's ongoing forecasting process. As described in the 29 August 2002 announcement and the Q2 trading update announcement of 22 October 2002, the Group's Sensitised Business Plan was based on the Group's Business Plan forecasts prepared in April 2002, to which a set of sensitivities were applied to reflect the scenario of more difficult market conditions and, in particular, a delay in market recovery beyond the end of 2003 as assumed in the Business Plan. The market for telecommunications equipment and services remains difficult. During the first three quarters of the current financial year the annualised rate of Core sales has declined by around 10 per cent. from approximately L2 billion in the first quarter to approximately L1.8 billion in the third quarter. 582

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- Corp and plc do not expect that the Group will benefit from a seasonal uplift in Core sales during the fourth quarter of the current financial year compared to the level recorded in the third quarter (L456 million), contrary to the seasonal pattern of customer demand in previous years. Furthermore, Corp and plc believe that market volumes are likely to contract further during the next financial year and do not expect to benefit from significant market share gains. As a result, the Group believes that Core sales could decline by a further 5 per cent. during the next financial year compared to the annualised third quarter trading levels (L1.8 billion). In December 2002, the Group outlined its Core operating model and confirmed its targets to achieve a gross margin run-rate in the range of 24 to 27 per cent. of Core sales and an operating expenditure run-rate in the range of 21 to 24 per cent. of Core sales during the next financial year ending 31 March 2004. The Group now believes that it will be able to reduce the Core operating cost base to an annual run rate below L450 million during the next financial year and thereby reduce its estimated breakeven level of sales to below L1.7 billion. The numbers in the illustrative analysis for fiscal 2005 have been reduced from the numbers presented in the Sensitised Business Plan published on 29 August 2002 and the updates provided in the 16 December 2002 announcement. These reductions reflect the difficulty in forecasting a market recovery and the additional cost saving measures that the Group has taken. Although it is difficult to predict the timing of a market upturn, the measures taken by the Group should position the Group well to benefit from any increase in demand, both financially and operationally. <Table> <Caption> Year ended 31 March 2005 L million ------------- <S> <C> Sales Rest of World 1,305 US Business 510 ------------- Total Sales 1,815 Gross Profit Rest of World 365 US Business 178 ------------- Gross Profit 543 EBITDA Rest of World 104 US Business 64 ------------- Total EBITDA 168 ============= </Table> CASH TO BE RETAINED BY THE GROUP IMMEDIATELY FOLLOWING THE RESTRUCTURING Corp and plc expect the Restructuring to be completed by no later than 31 May 2003. The tables below show projected financial information for the Group as at that date. Since the 16 December 2003 announcement, the Group has refined the projected cash it will need to retain after the Restructuring for the purposes of working capital, funding to breakeven and other restricted cash requirements. The expected cash balance retained has been reduced from L724 million to L602 million primarily as a result of the removal of the ESOP escrow. 583

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 4: PLC QUARTERLY REPORT TO 31 DECEMBER 2002 -------------------------------------------------------------------------------- The estimated cash balances as at 31 May 2003, assuming the Corp Scheme becomes effective on that date, are as follows: <Table> <Caption> L million ------------- <S> <C> Projected net cash outflows to breakeven (including net interest payable) (note 1) 96 Global working capital (note 2) 112 Cash in transit (note 3) 30 Working capital retained for Core business (note 4) 197 Cash collateralisation of performance bonds (note 5) 167 ------------- 602 ============= </Table> Note 1: Net Cash Outflows to Breakeven Cash retained by the Group to fund the business to its estimated breakeven point. This figure includes gross interest payable on the New Senior Notes of L36 million per annum and assumes that interest payable on the New Junior Notes is paid in kind. Gross cash outflows are shown net of proceeds (L27 million) forecast to be received after 31 May 2003 from certain identified asset disposals in the period to breakeven. Note 2: Global Working Capital It is estimated that approximately Ll12 million of cash is generally held at subsidiary levels and within joint ventures within the business as working capital for the worldwide operations of the Group. Note 3: Cash in Transit Normally, and hence also upon Restructuring, it is estimated that approximately L30 million of cash will be in transit and therefore not available for distribution. Note 4: Working Capital Retained for Core Business L197 million of cash will be retained for the working capital needs of the Core business. Working capital requirements include the funding of normal working capital swings which are the result of timing differences between receipts and payments, additional provisions for known and unknown contingent liabilities, as well as trading sensitivities to meet working capital requirements. Marconi Communications, Inc. expects to enter into a US working capital facility in an amount totalling approximately US$22.5 million (approximately L14 million). Note 5: Cash Collateralisation of Performance Bonds During the period prior to the Restructuring, certain new performance bonding agreements entered into by the Group have been structured on a cash collateralised basis. It is not anticipated that this cash will initially be available for distribution. In addition, a number of the Group's performance bond arrangements carry rights for the issuer to call for cash collateral, either unconditionally or upon the occurrence of certain events. The L167 million of cash retained with respect to performance bonds includes L42 million to be held in escrow to fund potential calls for collateral under these bonds. A further maximum of L25 million of cash released from performance bonds may be required under the new Performance Bonding Facility prior to being used to mandatorily redeem the New Junior Notes. 584

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 5 CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS Unless the context otherwise requires, this Appendix assumes that the Schemes will be implemented in accordance with their terms. The following discussion of the Corp Group's financial condition and trading performance should be read in conjunction with its consolidated financial statements and the related notes and the other financial information included in Appendices 1 and 2. Further information relevant to the following discussion and analysis can be found in the part I of this Document, and in particular: (i) the description of the Group contained in part I, Section 2, Part A; (ii) the risk factors described in part I, Section 2, Part F; (iii) the plc quarterly report contained in Appendix 4; and (iv) the financial information contained in Appendices 1 and 2. This commentary discusses and is based on the following financial information: (i) the audited financial information of the Corp Group for the three years ended 31 March 2002 and the six months ended 30 September 2002 contained in Appendix 1; and (ii) relevant unaudited financial information of the Corp Group for the six months ended 30 September 2001 contained in Appendix 2. The Group's consolidated financial statements are prepared in accordance with UK GAAP. This discussion contains forward looking statements based on assumptions about the Corp Group's future business, see "Forward Looking Statements". There are a number of factors that could cause the Corp Group's actual results and developments to differ materially from those expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include but are not limited to those discussed below and elsewhere in this document, particularly in part I, Section 2, Part F, Risk Factors. OVERVIEW The Group is a major international vendor of telecommunications equipment and services. The Group's customers include many of the leading telecommunications operators throughout the world, with whom it has a large base of installed equipment. CONTINUING OPERATIONS For the purposes of financial reporting, the Group, effective as of 31 March 2002, divided its continuing operations into two segments: Core and Capital. The Group divides its Core activities into two main business types: Network Equipment, comprising Optical Networks, Broadband Routing and Switching ("BBRS"), European Access, North American Access, Outside Plant and Power ("OPP") and Other Network Equipment; and Network Services, comprising Installation, Commissioning and Maintenance ("IC&M") and Value Added Services ("VAS"). Previously European Access, North American Access and OPP had been reported as Access Systems. The Group's customer base includes telecommunications companies and providers of internet services for their public networks, and certain large corporations, government departments and agencies, utilities and educational institutions for their private networks. Capital comprises certain non-core businesses the Group manages for value and ultimately for disposal. Assets in Capital include the Group's holdings in Easynet Group Plc, as well as a number of other minor activities, investments and assets. 585

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- On a geographic basis, the UK, rest of Europe, Middle East and Africa ("EMEA") and North America are the Group's main markets. The majority of the Group's revenues in the EMEA region relate to Optical Networks. Revenues in North America are driven by North American Access, OPP, and BBRS. DISCONTINUED OPERATIONS During the year ended 31 March 2002, the Group disposed of its Medical Systems, Data Systems and Commerce Systems activities which were previously managed within Marconi's Capital division. In August 2002, the Group completed the disposal of its Strategic Communications business which had previously represented substantially all of the Group's former Mobile division. In the accompanying financial information, Medical Systems, Data Systems, Commerce Systems and the Group's Strategic Communications businesses have been treated as discontinued operations throughout all periods. Further information on acquisitions and disposals is set out in part I, Section 2, Part A.2 and part IV, Appendix 19, Section 1.2 and 1.3. DEFINITIONS OF KEY PERFORMANCE INDICATORS In the subsequent discussion of the financial condition and results of operations of the Group, management has applied the following definitions: (a) Adjusted gross profit is defined as gross profit before exceptional items; (b) Adjusted gross margin is defined as gross margin before exceptional items; (c) Adjusted operating profit/(loss) is defined as operating profit/(loss) but before goodwill amortisation and exceptional items; (d) Adjusted operating costs are defined as research and development, selling and distribution and general and administrative expenses and the associated depreciation of tangible fixed assets and before goodwill amortisation and exceptional items; (e) Adjusted operating cash flow is defined as operating cash flows before exceptional cash flows and after net capital expenditure; and (f) Book to bill ratio is defined as orders received in the financial reporting period divided by sales made in the period. Additional key performance indicators and other terms are defined in part V. Unless otherwise stated, references to the "Group" refer to the Corp Group including its share of results of joint ventures but excluding its share of results of associates. Inflation has not had a material impact on the Group's results of operations for the six months ended 30 September 2002 and the three years ended 31 March 2002. One of the Group's strategic objectives is to maintain capital expenditure below the level of depreciation. BUSINESS REORGANISATION Following a profits warning published on 4 July 2001, the Group undertook an operational review of its activities. The results of the operational review were announced in September 2001 and included a change of management with the appointment of a new Chief Executive Officer and Interim Chairman. It also covered the Group's markets, its operations and scope of business and focused on adapting the Group to the changed circumstances of the telecommunications market during the substantial decline in market demand. The review resulted in: (a) the re-organisation of the Group into the Core businesses and a non-core Capital business from which the Group targeted to realise cash proceeds from disposals of at least L500 million by 31 March 2002, 586

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- (b) a plan to reduce plc Group indebtedness from L4.4 billion at 31 August 2001 to between L2.7 billion and L3.2 billion by 31 March 2002, which included a series of business disposals, (c) action plans to reduce the annualised operating expense run-rate in the then Core businesses (including the Group's Mobile assets) from around L1.4 billion at 31 March 2001 to around L1 billion by 31 March 2002.

Sales from continuing operations amounted to L1,019 million, a decrease of L609 million or 37 per cent. compared to the corresponding period of the previous financial year. This decrease was mainly the result of reduced demand in the global market for telecommunications equipment and services by telecommunications operators resulting in lower sales in the Group's Core businesses and the disposal of businesses from Capital, 587

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- including the Group's 50 per cent. stake in General Domestic Appliances ("GDA") and Marconi Optical Components completed during the previous financial year, as well as the sale of Marconi Applied Technologies Group completed in July 2002. Sales from discontinued operations amounted to L87 million during the period and related mainly to Strategic Communications prior to its disposal in August 2002. Of the L950 million of sales from discontinued operations during the first half of the previous year, approximately L133 million related to Strategic Communications. The balance of L817 million related to other business disposals including Medical Systems, Data Systems and Commerce Systems. GROUP ADJUSTED GROSS PROFIT (EXCLUDING JOINT VENTURES) <Table> <Caption> 6 months ended 30 September ---------------- 2001 2002 ------ ------ in L million <S> <C> <C> Continuing operations 358 177 Discontinued operations 270 24 ------ ------ Group 628 201 ====== ====== </Table> Adjusted gross profit at Group level amounted to L201 million, representing an adjusted gross margin of 18 per cent. (Sept 2001: L628 million; 26 per cent. of sales). Of this amount, the Group's continuing operations contributed an adjusted gross profit of L177 million and an adjusted gross margin of 17 per cent. (Sept 2001: L358 million; 22 per cent. of sales) and discontinued operations contributed an adjusted gross profit of L24 million and an adjusted gross margin of 28 per cent. (Sept 2001: L270 million; 28 per cent. of sales). The overall decrease in adjusted gross profit compared to the previous year at Group level was mainly attributable to the reduction in sales volumes in the Core businesses, unfavourable business mix and some price erosion, particularly in Optical Networks. As the Group was not able to reduce costs quickly enough, this led to under-utilisation of resources and under-recovery of costs in the supply chain. Business disposals included in discontinued operations also contributed to the absolute decrease in adjusted gross profit. In addition, a L25 million stock write-off was made in September 2002. Significant cost savings were made during the period but there were not able to offset the effect of the reductions in revenues.

This represented a L3 million improvement compared to the first half of the previous year. (Sept 2001: adjusted operating loss of L238 million). 588

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Of this, an adjusted operating loss of L233 million was attributable to the Group's continuing operations (L205 million of which related to the Core businesses and L28 million to Capital) and an adjusted operating loss of L2 million was attributable to the Group's discontinued operations.

The decline in second quarter sales compared to the first quarter was limited to L28 million, or 5 per cent. Market conditions have deteriorated in all geographic areas but the extent of the decline varies from country to country and depends on individual telecom operators' spending profiles. Sales in Europe, the Middle East and Africa ("EMEA") fell by L182 million, or approximately 24 per cent. to L570 million compared to the corresponding period of the previous financial year. Within the six months ended 30 September 2002, sales in the region remained stable quarter on quarter. Market dynamics in the UK showed signs of stabilisation. BT continued its broadband access campaign, which, while not leading to immediate sales for the Group, Corp expects over time to lead to increased traffic flows onto BT's core transmission network, requiring renewed spending in optical equipment. Italian market volumes also remained relatively stable mainly as a result of the absence of 3G debt issues amongst Italian telecommunications operators, although the pricing environment in Southern Europe generally became increasingly challenging. Elsewhere in Europe, major operators continued to cut capital expenditure budgets as they focused on debt reduction. This particularly impacted Core sales in Germany during this period. The further market decline was most marked in the Americas. Sales in the United States fell by L168 million, or approximately 36 per cent. to L295 million, while sales in CALA were down L91 million, or approximately 72 per cent. to L35 million compared to the corresponding period in the previous financial year. In the US, regional 589

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- bell operating companies continued to maintain tight controls over capital expenditure, further reducing overall budgets during the period, whilst political and macro-economic issues in CALA had a significant negative impact on the telecommunications market, particularly in Brazil and Mexico. Sales in APAC fell by L15 million or approximately 14 per cent. to L92 million. The decrease occurred mainly in Optical Networks as a result of increased competition and pricing pressure in the region. SALES CHANNELS Sales through channel partners were significantly lower than the first half of the previous year as a result of the overall reduction in market volumes and particularly, in the case of sales through Ericsson and Nokia, as a result of the completion of 2G and 2.5G wireless networks rollouts in the previous year and the ongoing delays to the deployment of 3G network rollout. PRICING A high proportion of Core sales, particularly in Europe, are derived from existing frame contracts. The Group estimates that price erosion in Network Equipment under such contracts ranges up to 8 per cent. on an annual basis. The Group aims to continue to match this price erosion with planned product cost savings to avoid further erosion of gross margins. Network Services tends to be more resilient to price erosion. COST OF SALES Material costs currently account for approximately three quarters of Network Equipment cost of sales, of which approximately one third relates to printed circuit board (PCB) assemblies outsourced through to CEMs and OEMs. The remaining cost of sales, which relates to in-house labour and overhead, includes costs associated with planning, supplier management, supply chain management and logistics, engineering, quality, final assembly and test, property costs, asset depreciation, logistics, system maintenance and warranty. Over 60 per cent. of Network Services' cost of sales currently relate to the cost of in-house labour. The remainder relates primarily to the cost of subcontract labour, materials and miscellaneous overheads. As a result of the rapid decline in revenues throughout the year ended 31 March 2002, the Group was not able to reduce its cost of sales quickly enough to avoid margin erosion. However, significant reductions in cost of sales have now been achieved in the Network Equipment supply chain and in Network Services. The rationalisation of all production and service areas is largely complete and the Irish and Montreal production facilities have been closed. In addition, substantial reductions in inventory levels have resulted in significant savings in warehousing and other inventory control costs. KEY CUSTOMERS The Core businesses serve a strong customer base of predominantly incumbent operators and government agencies. The ten largest customers during the first six months were BT, BellSouth, Metro City Carriers (Germany), Telecom Italia, Telkom South Africa, UK Government, US Federal Government, Verizon, Vodafone Group and Wind (Italy). In aggregate, these customers accounted for 46 per cent. of Core sales during the period (Sept 2001: 32 per cent.). BT remains the Group's largest customer and accounted for 17 per cent. of Core sales during the period (Sept 2001: 11 per cent.). In EMEA, the five largest customers during the first six months were BT, Metro City Carriers, Telecom Italia, UK Government and Vodafone Group. These customers, in aggregate, accounted for 55 per cent. of Core sales in the region during the period (Sept 2001: top five EMEA customers accounted for 31 per cent.). In the US, the five largest customers during the first six months were BellSouth, Qwest, SBC, Sprint, US Federal Government and Verizon and in aggregate accounted for 47 per cent. of Core sales in the region during the period (Sept 2001: top five US customers accounted for 46 per cent.). 590

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- ADJUSTED GROSS PROFIT Core gross profit amounted to L168 million, or 17 per cent. of Core sales. This included the impact of additional stock provisions of approximately L25 million charged to cost of sales in the second quarter of the financial year. In line with the Group's accounting policy, these stock provisions were created as a consequence of the continued decline in market conditions. They related mainly to optical networking and access equipment. For the purposes of this Core Business Review, the Group has analysed Core adjusted gross margin on an underlying basis, excluding the impact of these stock provisions. Underlying adjusted gross profit in the Core businesses (excluding inventory write-downs of L25 million) amounted to L193 million or 19 per cent. of sales (Sept 2001: L340 million; 23 per cent. of sales). The decrease compared to the previous year related mainly to reduced sales volumes in Network Equipment and IC&M activities, unfavourable business mix and some price erosion, particularly in Optical Networks. Significant cost savings were achieved and further cost reduction plans were implemented in order to address the continued under-utilisation of resources, particularly in the supply chain. On a sequential basis within the period, first quarter Core adjusted gross margin declined to approximately 17.5 per cent. of sales compared to 20 per cent. in the final quarter of the previous financial year. This was mainly due to the reduced level of sales volumes in the period (over L180 million lower than in the previous quarter) and the unfavourable business mix which more than offset cost reductions achieved in the supply chain during the period. In the second quarter, underlying adjusted gross margin in the Core businesses (excluding inventory write-downs of L25 million) improved sequentially to approximately 22 per cent. despite the further decline in Core sales. Approximately two-thirds of this improvement over the first quarter related to direct cost savings which included further manufacturing rationalisation, improved utilisation of resources in services and procurement and engineering cost reductions. The balance was driven by the more favourable business mix compared to the previous quarter. ADJUSTED OPERATING EXPENSES Core adjusted operating expenses totalled L373 million or 38 per cent. of Core sales during the period, a reduction of L214 million or 36 per cent. compared to the first half of the previous year (L587 million; 41 per cent. of Core sales). Significant savings were achieved across all main categories of operating expenditure. By the end of September 2002, the Group had reached an annualised operating expense run-rate in the Core business of L635 million, reduced from L1.1 billion at the end of September 2001 and L890 million at the end of March 2002. OPERATING EXPENSES -- RESEARCH & DEVELOPMENT ("R&D") Core R&D expenditure amounted to L163 million, (16.4 per cent. of Core sales) a 35 per cent. reduction compared to the first half of the previous financial year (L249 million: 17.2 per cent. of Core sales). Optical Networks accounted for almost 40 per cent. of the total Core R&D expenditure during the first half of the financial year (Sept 2001: approximately 30 per cent.). The main focus of R&D in Optical Networks remained the continued development of the Group's next generation SDH Series 4 product range and digital cross connect, the PMM metro DWDM product range and further upgrades to the Group's network management software. In July 2002, the Group announced its decision to terminate the development of its SONET technology and the consequent closure of its Canadian-based SONET facility, contributing to the overall R&D savings achieved during the period. R&D expenditure across the Group's access portfolio, in Europe and North America combined, accounted for a further 25 per cent. of total Core R&D expenditure. Ongoing development programmes were focused on fixed wireless access, Softswitch and Access Hub platforms as well as sustaining investment on certain legacy products to support existing customers. R&D investment in the North American Access Business was significantly reduced as a result of the Group's decision to cease investing in next generation fibre-to-the-home technologies. 591

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- BBRS accounted for 23 per cent. of Core R&D expenditure. Over 50 per cent. of this expenditure was focused on the development of the Group's new multi-service core switch, the BXR 48000. Other ongoing programmes include the further development of the ASX 1000 and ASX 4000 platforms. The remaining 12 per cent. of R&D expenditure in the period related mainly to the OPP Business, wireless software and Other Network Equipment. OPERATING EXPENSES -- SELLING AND DISTRIBUTION EXPENSES Core selling and distribution expenses amounted to L145 million, a 36 per cent. reduction compared to the first half of the previous financial year (L228 million). These savings were achieved mainly through headcount reductions, reduced spend on marketing programmes and initiatives, the consolidation and closure of several sales offices worldwide, and the transition to indirect sales channels in a number of countries, particularly in the APAC region. OPERATING EXPENSES -- ADJUSTED ADMINISTRATIVE EXPENSES Adjusted administrative expenses (defined as administrative expenses excluding goodwill amortisation, goodwill impairment and exceptional items, and excluding joint ventures) in the Core businesses amounted to L59 million, a 45 per cent. reduction compared to the first half of the previous financial year (L108 million). Savings were achieved mainly through headcount reductions and reduced spend on professional fees incurred in the normal course of business. Professional fees relating to the Group's Restructuring are classified as exceptional costs. OPERATING EXPENSES -- OTHER Other Core operating expenses amounted to approximately L6 million and related mainly to patent and royalty fees as well as to foreign exchange. (Sept 2001: operating income L2 million).

The significant reduction in adjusted gross profit was more than offset by the adjusted operating cost savings achieved during the period, giving rise to an overall improvement to adjusted operating loss of L42 million or 17 per cent. Core adjusted operating loss comprised an adjusted operating loss of L179 million in Network Equipment and an adjusted operating profit of L5 million in Network Services. In addition, the Core businesses incurred L31 million of other costs mainly relating to head office and other central costs. 592

NETWORK EQUIPMENT SALES Sales of Network Equipment amounted to L600 million, a decline of L343 million or 36 per cent. (Sept 2001: L943 million). Sales declined across all major product areas as a result of the further reductions in capital expenditure by the majority of telecommunications operators worldwide. Optical Networks Optical Networks sales declined by L115 million or 32 per cent. to L242 million (Sept 2001: L357 million). All areas of the business were affected as a result of a combination of three main factors: i) the general market downturn arising from further reductions in capital spending by many telecommunications operators; ii) priority by many operators to maximise utilisation in their existing core networks rather than proceeding with new network roll-outs; iii) a refocusing of the reduced investment, by certain customers, from core transmission networks to broadband access equipment. Sales of SDH equipment accounted for around 80 per cent. of total Optical Networks sales during the period (Sept 2001: 75 per cent.) and DWDM for around 15 per cent. (Sept 2001: 15 per cent.). This split reflected the higher proportion of orders for in-fill equipment relating to existing networks which are typically based on low-capacity SDH technology, as opposed to new network build which would be oriented towards high-capacity SDH and DWDM technology. The balance represented sales of network management software and a small amount of SONET equipment sold prior to the Group's decision to cease further development and sales of this technology. Despite the overall reduction in market size, and the 27 per cent. decline in sales of SDH equipment during the period, the Group maintained its market share in all areas of SDH with the exception of its position in digital cross connects. In September 2002, the Group announced the availability of its next generation digital cross connect, the MSH2K, which is currently on trial in a number of European customers' labs and for which the Group has been awarded initial orders. 593

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Sales of DWDM equipment fell 28 per cent. compared to the level recorded in the first half of the previous year. This was mainly a result of the high proportion of sales to China Railcom in the previous year as the Group completed the deployment of equipment for the North West Ring project, which was not repeated in the first half of 2003. Sales were down across all geographic regions. In EMEA, the Group's main market for Optical Networks equipment, sales performance varied across countries. Sales increased in the United Kingdom in comparison to the low level recorded in the first half of the previous year, and also in Italy as a result of continued network rollouts, particularly by Wind and Vodafone-Omnitel. These increases were more than offset, however, by declines in direct and indirect sales through channel partners in other European markets mainly as a result of general market softness. This trend was particularly marked in Germany as a result of the completion of the Group's rollout of SDH equipment under a frame contract to Deutsche Telekom ("DT"), and continued capital expenditure reductions by DT and other German wireline and wireless operators. Sales in CALA were affected by the uncertain macroeconomic and political environment prevalent in the region during the period. Sales in APAC decreased as a result of the completion of the North West Ring project in China in the previous year and because of increased competition in the region. Broadband Routing and Switching (BBRS) BBRS comprises mainly sales of multi-service switching products such as the ASX 4000 multi-service core switch and the smaller ASX and TNX edge switches and a range of legacy ATM switching and routing products designed for enterprise customers. During the period, the Group began to ship the first units of its new high capacity multi-service core switch, the BXR 48000, to the US Federal Government. Sales of BBRS equipment decreased by L40 million or 35 per cent. to L73 million (Sept 2001: L113 million). Sales to customers requiring carrier-class networks accounted for 64 per cent. of BBRS sales during the first half (Sept 2001: 62 per cent. of sales). This included sales to the US Federal Government, the Group's single largest customer for BBRS equipment, which increased in comparison to the prior period, mainly as a result of increased shipments of ATM edge switching equipment and the first sale of the BXR 48000. This increase partially offset the substantial decline in sales to service provider customers resulting from the significantly reduced capital spending by US operators. Sales to enterprise customers accounted for 36 per cent. of BBRS sales during the first half (Sept 2001: 38 per cent). This decrease in sales to enterprise customers followed the Group's decision, in 2001, to refocus its technical and commercial resources towards customers requiring carrier class networks. BBRS service sales are reported as part of VAS within Network Services. These amounted to L43 million during the first half of the financial year, a 16 per cent. increase on the corresponding period in the prior year (L37 million). This increase was due to one specific major contract for airport communications services in the United States, which the Group expects to complete before the end of the current financial year. European Access European Access comprises Fixed Wireless Access (accounting for approximately 34 per cent. of European Access sales), Multimedia Voice Systems (approximately 24 per cent.), the Group's High Density DSLAM, the Access Hub (over 10 per cent.) and other, mainly narrowband access products (representing the balance of approximately 30 per cent.). Sales of European Access equipment fell by L61 million or 32 per cent. to L128 million (Sept 2001: L189 million). Within the period, at L69 million, second quarter sales were 17 per cent. higher than the first quarter (L59 million) as a result of increased sales of High Density DSLAM in Italy and voice systems in the United Kingdom. Sales fell compared to the prior period across all main product areas with the exception of sales of the Group's High Density DSLAM product, launched during the first half of the previous financial year. The increase in DSLAM sales was due particularly to increased volumes in the Italian market during the second quarter of the financial year, as Telecom Italia aggressively deployed the Group's equipment under an existing frame contract. 594

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Conditions remained tough in Germany, the Group's main market for its fixed wireless access products. Sales were down compared to the first half of the previous year mainly as a result of the high levels of debt amongst German mobile operators, leading them to focus on balance sheet restructuring and tight constraints on capital spending. Delays to planned 3G network rollouts during the first half also contributed to the difficult business environment. Two major operators, O(2) and D2 Vodafone, have recently confirmed 3G network rollout plans and are now beginning initial deployments of equipment. In October 2002, the Group was awarded a major new frame contract from mobile operator O(2)'s German subsidiary for the supply of fixed wireless access and optical networking equipment to support its planned 3G network roll-out. Sales of multimedia voice systems were down compared to the corresponding period in the previous year as the Group's customers, including BT, continued to switch investment from their narrowband access to broadband access networks. North American Access Sales fell by L17 million or 26 per cent. to L48 million (Sept 2001: L65 million). This was mainly due to the difficult market conditions in North America and the continued slowdown of narrowband access infrastructure investment. Sales of the Group's legacy DISC*S copper product range were particularly affected following the Group's announcement in March 2002 that it had discontinued future research and development spending in this area. Outside Plant and Power (OPP) OPP equipment sales fell by L76 million or 49 per cent. to L80 million (Sept 2001: L156 million). This was mainly a result of the significant reductions in capital spending in the United States, which accounted for L74 million of OPP sales during the period (Sept 2001: L129 million). The general market downturn in CALA also contributed to the sales decline. OPP recorded L6 million of sales in CALA during the first six months, compared to L26 million in the corresponding period of the previous financial year. OPP service sales are reported as part of IC&M within Network Services. These amounted to L51 million during the first half of the financial year, a reduction of L57 million, or 53 per cent. compared to L108 million in the corresponding period of the previous year. This decline was a direct result of the reduced level of sales of OPP equipment. Other Network Equipment Other Network Equipment comprises mainly MIS, the Group's interactive systems activity, as well as legacy operations in South Africa and APAC. Sales in this group of activities fell by L34 million or 54 per cent. to L29 million (Sept 2001: L63 million). This was mainly the result of reduced sales in the Group's legacy optical cable business in South Africa and the absence of sales in Hong Kong following completion of a major long-term contract during the previous financial year. Sales of interactive systems remained stable during the period. NETWORK EQUIPMENT: ADJUSTED OPERATING LOSS Network Equipment incurred an adjusted operating loss of L179 million, an improvement of L37 million or 17 per cent. compared to an adjusted operating loss of L216 million in the first six months of the previous financial year. The main product areas contributing to this improvement during the period were BBRS and North American Access. Operating performance improvement in Optical Networks remains difficult in the face of continued volume reductions, contractual annual price negotiations under existing frame contracts and some price erosion on new orders as well as issues relating to business and geographic mix. 595

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- NETWORK SERVICES SALES Sales of Network Services amounted to L392 million, a reduction of L113 million or 22 per cent. (Sept 2001: L505 million). Whilst sales fell across both main types of service activity, the decline was most marked in the field of IC&M, which accounted for 47 per cent. of Network Services sales during the period (Sept 2001: 54 per cent.). Installation, Commissioning and Maintenance (IC&M) IC&M sales fell by L85 million or 31 per cent. to L186 million (Sept 2001: L271 million) as a direct result of the decline in equipment sales to telecom operators with which these services are associated. Approximately L65 million, or around 76 per cent. of this decline, occurred in the Americas and related mainly to sales of OPP services. In EMEA, which accounted for approximately 65 per cent. of IC&M sales during the period (Sept 2001: 52 per cent.), sales were down around 14 per cent., with an increased level of installation and commissioning activity in Italy partially off-setting higher percentage declines in other countries. This was due to the phasing of network deployments by Telecom Italia, Vodafone-Omnitel and Wind during the final quarter of the previous year and during the first half of the current year. IC&M sales are not common in APAC as these activities tend to be handled by the Group's local partners in the area. Value Added Services (VAS) Overall, VAS sales fell by L28 million or 12 per cent. to L206 million (Sept 2001: L234 million). Sales in Integrated Systems and Managed Services remained relatively stable and were offset by a decline in Wireless Services. On a sequential basis, VAS sales increased from L97 million in the first quarter to L109 million in the second quarter as a result of increased trading under long-term service contracts, particularly in the transportation and government sectors. During the first half of the previous financial year, Integrated Systems benefited from a high proportion of sales arising from the completion of the long-term Jubilee Line Extension communications project for London Underground. Excluding the impact of this one major contract, the increase in underlying sales of Integrated Systems was driven by trading under long-term service contracts during the period, particularly in the United Kingdom (e.g. West Coast Main Line) and Germany (e.g. Ramstein). Managed Services recorded a single-digit percentage decrease during the period. Increased sales of BBRS-related services were offset by lower sales of IT outsourcing services prior to the Group's ongoing managed exit from this activity. Sales of Wireless Services decreased by over 30 per cent. during the period. This was mainly a result of reduced capital expenditure in the wireless market affecting all geographic areas, but most notably the Americas. NETWORK SERVICES: ADJUSTED OPERATING PROFIT Network Services recorded an improvement in adjusted operating profit from L2 million in the first half of the previous financial year to L5 million during the period. Improved resource utilisation in IC&M and other ongoing cost reduction initiatives were the main drivers of the increased profitability. While improvements were recorded across most major service activities, wireless services generated an operating loss during the period mainly as a result of the substantially lower sales recorded during the period. 596

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- GROUP REVIEW -- OTHER FINANCIAL ITEMS 6 MONTHS ENDED 30 SEPTEMBER 2002 COMPARED WITH 6 MONTHS ENDED 30 SEPTEMBER 2001 EXCEPTIONAL ITEMS OPERATING EXCEPTIONALS For the six months ended 30 September 2002, exceptional items charged to Group operating loss (excluding joint ventures and associates) totalled L206 million, of which L24 million was charged to cost of sales and L182 million was charged to administrative expenses. Of the total, exceptional restructuring and reorganisation costs amounted to L190 million. Impairment of tangible fixed assets, relating mainly to impairment of the Group's remaining assets for mobile communications (included in Capital) and operations in South Africa, and a provision for onerous leases amounted to L31 million. These were partially offset by exceptional income of L15 million arising from the release of previously established exceptional provisions with respect to certain doubtful debtors mainly in the United Kingdom, and to the settlement of litigation relating to IT costs at an amount less than originally envisaged. The exceptional restructuring costs related mainly to the restructuring of the Group's supply chain and other facilities, including fixed asset impairments associated with the downsizing of the Core businesses (L98 million) and costs associated with headcount reductions (L67 million). The balance related mainly to costs associated with the Group's Restructuring. A further review of the carrying value of the Group's fixed assets (subsequent to the review performed at 31 March 2002), including goodwill, was undertaken at 30 September 2002. The average discount rate applied to the future cash flows was 15 per cent. and was based upon a weighted average cost of capital percentage. The results of the review indicated that no further goodwill impairment charge was necessary for the six months to 30 September 2002. However, due to the significant uncertainties over the timing and extent of any recovery in the telecommunications market, Corp acknowledges that the Group is likely to have to continue to review its assumptions against future performance. In addition, the Group recorded L18 million of exceptional costs in relation to its share in associates and L31 million relating to the impairment of intangible assets in its joint ventures. Exceptional items charged to Group operating loss (excluding joint ventures and associates) in the six months ended 30 September 2001 totalled L4,501 million. This was made up of a L3,493 million charge to write-down goodwill and tangible fixed assets, a L148 million to increase doubtful debt provisions and a L518 million increase in provisions for slow-moving stock and related charges. Restructuring and reorganisation charges totalled L342 million and included exceptional charges for workforce reductions and the IT systems implementation programme. The more uncertain sales outlook and more conservative assessment of future growth prospects of acquired businesses led to the Corp's decision to write-down the value of historical goodwill and tangible fixed assets by L3,493 million. This charge comprised L3,407 million to write-off purchased goodwill and L86 million for the impairment of tangible fixed assets. The goodwill impairment related primarily to FORE Systems, RELTEC Corporation, Metapath Software International, Inc. ("MSI") and Mariposa Technology, Inc. The increase in provisions for slow-moving and obsolete stock and related charges was taken as a consequence of the more uncertain sales outlook and the decision to scale back certain product lines. Corp's decision to increase doubtful debt provisions was taken following a review of debtor balances in light of the changed conditions in customers' markets and recognised the possibility of payment concerns with respect to specific customer groups. 597

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- NON-OPERATING EXCEPTIONALS For the six months ended 30 September 2002, non-operating exceptional charges (excluding joint ventures and associates) amounted to L14 million. This comprised a L5 million net loss on disposal of discontinued operations, a L9 million net loss on disposal of fixed assets and investments in continuing operations. In addition, a L3 million loss was recorded relating to the Group's share of associates' non-operating exceptional charges. Of the L9 million net loss in continuing operations, L40 million related to the write-down of some of the Group's investments in accordance with its accounting policy whereby listed investments are marked to their market value at the end of each reporting period and unlisted investments are booked at their net realisable value. This write-down was partially offset by a L28 million curtailment gain associated with retirement benefits arising mainly from the disposal of the Group's share in GDA, a L12 million gain on property disposals and a net L9 million charge relating to current and prior period disposals and business closures and other provision movements. In discontinued operations, the loss on disposal of Strategic Communications (L41 million) was partially offset by the release of provisions relating to Medical Systems and other previously completed disposals. INTEREST AND FINANCE INCOME In the six months ended 30 September 2002, the Group's net interest payable was L119 million (Sept 2001: L122 million). The interest charge decreased as a result of the Group's reduced net debt position. The charge during the period mainly comprised approximately L77 million of interest charged on the Group's bond debt and approximately L52 million of interest charged on the Group's Syndicate Bank debt, partially offset by interest income on the Group's cash balances and repayment supplement on tax refunds. Net finance income amounted to L2 million. TAXATION The tax charge on ordinary activities was L10 million in the period compared with a credit of L36 million in the first half of the previous year. The net tax impact of exceptionals was Lnil (Sept 2001: Lnil). GOODWILL AMORTISATION The Group incurred a charge of L55 million for goodwill amortisation for the six months ended 30 September 2002 (including L1 million for amortisation of goodwill relating to joint ventures) compared to a charge of L350 million in the corresponding period of the previous year. This significant reduction was a result of the reduced carrying value of goodwill on the Group's balance sheet following the exceptional goodwill impairment charges in the year ended 31 March 2002. EARNINGS PER SHARE Basic and diluted loss per share, which reflects goodwill amortisation and exceptional items was 92.5 pence (Sept 2001; loss of 182.3 pence). The loss per share excluding goodwill amortisation and exceptional items was 38.0 pence compared to a loss per share of 10.7 pence in the first half of the previous year. 30 SEPTEMBER 2002 -- FINANCIAL CONDITION BALANCE SHEET Three main factors have contributed to the overall change in shape of the Group's balance sheet during the first half of the financial year: (i) the disposal of Strategic Communications; (ii) the losses incurred during the period and (iii) the further market decline and continued downsizing of the Group's Core businesses. 598

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- NET ASSETS/LIABILITIES As at 30 September 2002, net liabilities before net retirement benefit deficits stood at L2,772 million compared to L1,890 million at 31 March 2002. The increase in net liabilities was mainly due to the loss incurred during the period. As at 30 September 2002, the Group had net current liabilities of L1,331 million compared to net current liabilities of L756 million as at 31 March 2002. The increase in net current liabilities was mainly due to reductions in cash due to continuing losses, and reduction in stock and debtors reflecting lower sales, offset by a reduction in trade creditors and short-term borrowings. FIXED ASSETS The L672 million of goodwill on the balance sheet at 30 September 2002 related mainly to the acquisitions of GPT and RELTEC Corporation, businesses acquired from Nokia and Bosch, respectively. The decrease from L877 million at 31 March 2002 arose as a result of the disposal of Strategic Communications and Marconi Applied Technologies (L121 million), the amortisation charge incurred during the period (L54 million), currency effects (L21 million) and a reduction of L9 million due to the lapsing of certain share option consideration relating to acquisitions in previous periods. Tangible assets decreased by L193 million from L522 million at 31 March 2002 to L329 million at 30 September 2002. This was mainly due to depreciation (L79 million), the disposals of Strategic Communications and Marconi Applied Technologies (L56 million), fixed asset impairments as a result of the downsizing and restructuring of the Core businesses (L49 million), and foreign exchange movements. Capital expenditure during the period was restricted to items essential to support the business. Investments decreased by L129 million from L250 million at 31 March to L121 million at 30 September 2002. This was mainly due to the Group's share of the losses of Easynet Group Plc and write-downs of a number of the Group's other investments. WORKING CAPITAL The disposal of Strategic Communications led to a reduction of L162 million in net stock and contracts in progress, a reduction of L318 million in net debtors and a reduction of L320 million in trade, other creditors and accruals compared to the position at 31 March 2002. At Group level, net stock and contracts in progress reduced by approximately L364 million to L356 million (31 March 2002: L720 million). In the Core businesses, net stock and contracts in progress reduced by L177 million. L25 million of this reduction related to the additional stock provisions raised during the period. Significant improvement in the Group's process to align the purchase of new stock with forecast sales demand was a major driver behind the inventory reduction achieved during the period. The increase in Core net stock turns from 4 to 5.1 reflected this improved utilisation and management of inventory. Group net debtors decreased by approximately L642 million to L862 million (31 March 2002: L1,504 million). Core net trade debtors decreased by approximately L105 million partly as a result of the reduced trading volumes during the period and partly as a result of the Group's focus on the management of debtor collection and overdue debts. Net Core trade debtor days increased from 87 at 31 March 2002 to 107 at 30 September 2002. The low level in March 2002 reflected the impact of the one-off sale of SDH inventory to BT in the final quarter of the previous year. Excluding this impact, net Core trade debtor days at 31 March 2002 stood at 103. The level of net trade Core debtor days remained high mainly as a result of the relatively high proportion of sales in Southern Europe and APAC, where payment terms tend to be significantly longer than average. Other debtors and prepayments in the Core businesses increased by L27 million to L190 million. This was mainly due to an increase in prepayments on annual contracts payable at the beginning of the financial year. Trade, other creditors and accruals fell from L1,920 million at 31 March 2002 to L1,421 million, a reduction of L499 million. Trade creditors in the Core businesses were reduced by L65 million to L262 million. Core trade creditor days remained stable during the period at 54 days after adjusting the March position to exclude the one-off impact of the sale of SDH inventory to BT in the final quarter of the previous year. Other creditors and accruals in the Core businesses reduced by L243 million to L505 million due largely to the conversion of interest 599

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- swap arrangements into loans, the payment of accrued interest on the Group's Eurobonds and a payment made to Court in relation to litigation concerning one of the Group's joint ventures, Ultramast Limited. PROVISIONS Provisions for liabilities and charges stood at L456 million at 30 September 2002, a net reduction of L49 million compared to 31 March 2002 (L505 million). Share option and restructuring provisions accounted for L176 million (31 March 2002: L179 million) and L69 million (31 March 2002: L96 million), respectively. The remainder included provisions for warranty and contract losses, industrial injury claims, supplier obligations and provisions related to previous disposals. In addition to the normal movements in warranty and contract loss provisions, provisions were increased to provide for losses on industrial injuries. These movements were offset by disposals and currency movements. RETIREMENT BENEFITS The net retirement benefit deficit increased by L313 million from L126 million at 31 March 2002 to L439 million at 30 September 2002. This was mainly the result of adverse variances between the actuarial assumptions and actual results for returns on plan assets and discount rates used to value liabilities. These actuarial assumption losses are reflected through the Statement of Total Recognised Gains and Losses. The main component of the pension liability at 30 September 2002 is the deficit on the funded UK Plan (L298 million). The balance relates to retirement benefit plans in Germany, Italy and the United States. The UK Plan's exposure to equity markets is limited to 21 per cent. of plan assets totalling L2,355 million. The remaining scheme assets are held in bonds (72 per cent.) and property and cash (7 per cent.). In assessing the funding rate, the actuary uses a different set of assumptions to that required by the FRS17 accounting standard and takes a broader view of the fund's income generating capacity over a longer period. Based on a preliminary view of the actuary to the UK Plan's latest triennial actuarial review, the Group and the trustee of the UK Plan have agreed adjustments to pension contributions with effect from 1 November 2002. At L23 million, the operating charge relating to retirement benefits for the six months ended 30 September 2002 was lower than the corresponding charge in the previous year (H1 2002: L26 million) due to a reduction in the number of plan members. The Group recognised curtailment and settlement gains during the reporting period of L66 million. These related mainly to the disposal of Strategic Communications and the Group's 50 per cent. stake in GDA. VENDOR FINANCE The Group, like its competitors, continues to experience demand for financing from its customers. However, this demand has decreased significantly due to market conditions and the Group's focus on its core base of incumbent carrier customers. When the Group has supported customer financing requests, it has significantly limited its own risk by: i) leveraging funds from third party financiers' having strategic interests aligned with the Group, and ii) developing innovative commercial alternatives that do not involve long-term cash investments from the Group. Through these actions, the Group has satisfactorily accommodated most customer financing requests and will not require Group cash resources to fund these activities in the foreseeable future. As at 30 September 2002, the Group had vendor finance commitments of approximately L68 million, of which L54 million had been drawn. The reduction, compared to commitments of L100 million at 31 March 2002, was primarily due to an agreement with a customer to cancel vendor finance commitments which had become unlikely to be drawn. In addition, the Group uses export credit agencies to assist in managing political and credit risks on major contracts and makes extensive use of export credit insurance in respect of small to medium-sized contracts. 600

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- NET DEBT Net debt was L3,514 million at 30 September 2002 compared to L3,335 million at 31 March 2002. The increase of L179 million resulted from the Group's cash outflow of L132 million, a favourable foreign exchange movement of L159 million and a net L206 million of other non-cash movements relating to interest swap arrangements converted to new loan agreements during the period, debt transferred to Finmeccanica S.p.A upon disposal of Strategic Communications and the write-off of the loan balance with Marconi plc. At 30 September 2002, net debt comprised L4,576 million of gross financial debt made up of L2,059 million of Eurobond debt and US dollar bond debt, L2,117 million of the Syndicate Bank debt (including L51 million as at 30 September 2002 relating to the conversion of interest swap arrangements to new US dollar loans with the Syndicate Banks during the period) and L105 million of bilateral and other bank debt, together with a L295 million creditor with plc and fellow subsidiaries of the plc Group and L1,062 million of cash. SYNDICATE BANK AND BOND DEBT At 30 September 2002, drawings under the Group's Bank Facility Agreement amounted to an equivalent of L2,066 million, comprising of actual drawings of L650 million and US$2,226 million. At 30 September 2002, the Group had Yankee Bond debt outstanding with principal amount US$1,800 million (L1,146 million) and Eurobond debt outstanding with principal amount E1,500 million (L943 million). The difference between the principal amounts totalling L2,089 million and the balance sheet value of bond debt totalling L2,059 million related to discounts and related fees. The sterling equivalent amounts of Syndicate bank debt and Bonds outstanding reduced compared to the respective values at 31 March 2002 as a result of foreign exchange translation. In addition, interest rate swap arrangements totalling approximately L54 million were converted to new loan agreements during the period. 6 MONTHS ENDED 30 SEPTEMBER 2002 -- CASH FLOW The Group incurred a L132 million cash outflow before use of liquid resources and financing during the six months ended 30 September 2002. The main components of this outflow were a net adjusted cash outflow from operating activities before exceptional items of L142 million, an exceptional cash outflow from operating activities of L181 million, net interest paid of L158 million and other net cash outflows of L38 million. These outflows were partially offset by net cash inflows from disposals of L387 million. ADJUSTED OPERATING CASH FLOW Adjusted operating losses of L285 million, partially offset by depreciation and amortisation of L133 million and a L10 million cash inflow from working capital movements led to the Group's operating cash outflow before capital expenditure of L142 million during the period. The Group recorded significant progress in reducing adjusted operating cash outflows within the period, with the outflow of L117 million after capital expenditure in the first quarter reducing to L52 million in the second quarter. This improvement was predominantly driven by progress within the Core businesses, where adjusted operating cash outflow reduced from L81 million in the first quarter to L43 million in the second quarter. This was a result of the reduced operating losses and increased contribution from working capital. There was a L30 million reduction from working capital during the first half, which was largely driven by improved utilisation of inventory, partially offset by a reduction in creditors. CAPITAL EXPENDITURE AND FINANCIAL INVESTMENT One of the Group's strategies is to maintain capital expenditure below the level of depreciation. Capital expenditure amounted to L27 million during the period, of which L19 million related to the Core businesses. The Group has maintained capital expenditure well below the level of depreciation, which amounted to L79 million, of which L70 million related to the Core businesses. Core capital expenditure is generally focused on development models, test equipment, sales demonstration equipment and R&D laboratory equipment. During 601

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- the period, the majority of Core capital expenditure was incurred in the Optical Networks and BBRS Businesses. Proceeds from disposals of fixed assets amounted to L20 million and mainly related to property disposals. Financial investments contributed a net L18 million cash outflow during the period. This related mainly to a cash payment made in to Court in relation to litigation concerning one of the Group's joint ventures, Ultramast Limited. RETURNS ON INVESTMENTS AND SERVICING OF FINANCE Net interest paid during the period amounted to L158 million, comprising mainly interest paid on the Group's syndicate bank and bond debt, partially offset by interest received on a refund relating to tax paid in prior years and on the Group's cash balances. Interest paid on the Group's outstanding Eurobond and Yankee Bond debt amounted to approximately L129 million. This comprised L56 million paid on 2 April 2002, the first business day following the bond coupon due date of 30 March 2002 and L73 million interest due and accrued up to 15 September 2002 and paid prior to 30 September 2002. Approximately L52 million of interest was paid on the Group's syndicate bank debt. As part of the proposed Restructuring, L340 million is to be distributed to the relevant Scheme creditors, in addition to L95 million paid in respect of due and accrued interest. Of this L95 million, L8 million was paid on 30 August 2002, L66 million was paid on 15 September 2002 and L4 million was paid on 30 September 2002. In addition, after the period end, L14 million was paid on 15 October 2002 and L3 million was paid on 4 November 2002. EXCEPTIONAL CASH FLOWS The Group incurred operating exceptional cash costs of L181 million during the first half of the year. Over half of this amount related to the direct cash cost of severance payments and site closures in the context of the Group's operational restructuring and reorganisation. The balance related to cash costs associated with the Group's manufacturing outsourcing programme and payments made under onerous contracts and as a result of supplier liability claims. The payment of fees and expenses to advisors in the context of the Group's Restructuring is also included in operating exceptional cash flows. CASH FLOWS FROM ACQUISITIONS AND DISPOSALS Net proceeds from acquisitions and disposals led to a net cash inflow of L387 million during the first half of the year. This related mainly to the disposals of Strategic Communications and Marconi Applied Technologies, partially offset by the payment of transaction-related costs and fees. TAX PAID The Group paid L13 million net of repayments in relation to tax including US state taxes on gains on disposals. There were no tax payments or receipts relating to hedging arrangements during the period. CURRENT LIQUIDITY POSITION The Group has funded its liquidity requirements mainly through a combination of internally generated funds, bank borrowings, debt issues in the capital markets and the disposal of non-Core businesses. Prior to the completion of the Restructuring, the Group is unable to arrange any new lending facility or to raise new funds through the issuance of debt or equity securities. Consequently, the Group has little or no ability to obtain new external funding and does not expect to have such ability unless and until the proposed Restructuring is complete. As previously disclosed, the majority of the Group's cash resources are currently held in secured accounts which are subject to interim security arrangements in favour of the Group's Syndicate Banks and Bondholders (including the bond trustees) and also in favour of Barclays, as the sole ESOP Derivative Bank who, prior to 15 October 2002, committed to support the proposed Restructuring. The secured accounts were created at the end of April 2002 in accordance with the previously disclosed lock box arrangements entered into in favour of the Syndicate Banks and Bondholders. The interim security arrangements contemplated by the Heads of Terms were 602

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- implemented on 13 September 2002. At that time, the balance of the secured accounts was approximately L866 million. At 30 September 2002, the balance of the secured cash amounted to L735 million. The Group is dependent on amounts available to it from the secured amounts in order to meet its short-term liquidity needs. Prior to the release of interim security and so long as an enforcement event does not occur, releases from the secured accounts will be approved in accordance with the Group's revised monthly cash flow forecast, subject to specified maximum amounts. This schedule takes account of the Group's anticipated cash inflows and outflows, and is consistent with the Group's expectations as to its liquidity needs in the period prior to the expected completion of the Restructuring. At 30 September 2002, the Group had a total restricted cash balance, defined as cash pledged or advanced as collateral, of L880 million. Of this, L775 million reflected the cash in the secured accounts described above, L79 million reflected cash collateral placed against bonding facilities; L18 million reflected cash in the Group's captive insurance company and L15 million reflected cash deposited against secured loans in Italy. In addition, L25 million has been placed in an escrow account pending determination of certain claims of the Group's ESOP Derivative Banks in respect of certain previously disposed companies. The remaining L8 million represents other restricted cash. Of the Group's L182 million unrestricted cash held outside of the secured accounts as at 30 September 2002, L116 million was a combination of cash in transit and global working capital balances with the remaining L66 million held in money market deposits in the Group's treasury centres. CONTRACT BONDING FACILITIES Some customers in the telecommunications market require that bank bonds or surety bonds (those issued by insurance companies) are provided to guarantee performance of the supplier. Group companies had L221 million of such bonds outstanding as at 30 September 2002 with both banks and insurance companies world-wide. The reduction from L500 million of bonds outstanding at 31 March 2002 was mainly the result of the disposal of Strategic Communications. Some of these facilities are covered by counter indemnities from Corp and others have individual indemnities from other Group companies. The Group's bonding is normally provided on an uncommitted basis. As a consequence of the Group's ongoing Restructuring, all new bonds currently have to be cash collateralised. Since February 2002, Marconi Bonding Limited (a special purpose vehicle used for this purpose) has procured the issue of approximately L80 million of performance bonding (on a fully cash collateralised basis) on behalf of other Group companies. A maturity profile of all bonds and guarantees outstanding at 30 September 2002 is set out below: <Table> <Caption> As at 30 September 2002 ------------ Lm <S> <C> 2003 or earlier 72 2004 10 2005 16 2006 45 2007 25 Thereafter 4 No expiry date 49 ------------ Total 221 ============ </Table> A number of the Group's performance bonding arrangements carry rights for the issuer to call for cash collateral, either unconditionally or upon the occurrence of certain events. The Group estimates that as at 30 September 2002, performance bonds with a face value of approximately L89 million have varying rights to call for cash collateral. 603

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Bonding and guarantee facilities will frequently run beyond the contracted maturity dates indicated in the table above. In addition, there are a number of bonds with no expiry date. These may be cancelled by the beneficiaries when the guaranteed works are completed. OBLIGATIONS The Group has obligations beyond the current financial period in terms of long-term debt, equity forward contracts, finance leases and operating leases. In addition to the L2,091 million of long-term debt and finance leases reported as at 30 September 2002, other long-term financial obligations were as follows: <Table> <Caption> As at 30 September 2002 ------------------------------- Equity Forward Operating Contracts Leases Total --------- --------- ----- in L million <S> <C> <C> <C> 2004 -- 26 26 2005 123 23 146 2006 -- 19 19 2007 -- 17 17 Thereafter -- 79 79 --------- --------- ----- TOTAL 123 164 287 ========= ========= ===== </Table> In addition, at 30 September 2002, the equity forward contracts had accrued interest of L44 million.

Sales from continuing operations decreased L1,752 million or 36 per cent. compared to the corresponding period of the previous financial year. This decrease was mainly the result of reduced demand in the global market for telecommunications equipment and services by telecommunications operators and companies. 604

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Sales from discontinued operations decreased L623 million or 31 per cent. compared to the corresponding period of the previous financial year. This decrease was mainly the result of the inclusion of only five months trading for Medical Systems, and ten months trading for Commerce Systems and Data Systems in the year ended 31 March 2002 compared to a full twelve months in the year ended 31 March 2001.

(2001: 36 per cent.). The reduction in adjusted gross profit in the period was most significant in the Core businesses, accounting for approximately 79 per cent. of the decline. A significant proportion of this was due to the sizeable reduction in trading volumes experienced during the year. The speed of this deterioration in sales was more rapid than the Group's ability to re-scale the cost base of the business. This, in turn, led to an under-utilisation of resources in the Network Services business and under-recovery of cost in the supply chain, which accounted for the further reduction in adjusted gross profit. Contractual annual price negotiations under existing frame contracts, some price erosion on new Optical Networks orders and issues relating to business mix also contributed to the decline. Within Capital, the disposal of businesses completed during the year, such as the Group's optical components business and GDA, contributed to a L30 million decrease in adjusted gross profit, while the businesses disposed in fiscal 2001 such as Woods Air Movement and Avery Berkel Group contributed approximately L22 million to adjusted gross profit in 2001, which was not repeated in fiscal 2002.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- profit of L104 million by its discontinued operations. This compares to a Group adjusted operating profit of L754 million in the previous year. The decline in adjusted gross profit before exceptional items was partly offset by savings in operating expenses achieved during the year as a result of cost reduction initiatives arising from the Group's operational review completed in September 2001. OPERATING EXPENSES -- R&D Total Group expenditure on R&D (excluding joint ventures) amounted to L628 million (2001: L626 million), representing approximately 15 per cent. of sales (2001: 9 per cent.). The Group invested L486 million (2001: L469 million) of this amount in Core businesses, an increase of approximately 4 per cent. compared to the previous year. This investment represented 18 per cent. of Core sales (2001: 11 per cent.). This increase in absolute expenditure and as a percentage of sales was mainly the result of higher R&D costs in the BBRS and Optical Networks businesses, driven by the development and launch of key products such as the BXR 48000 multi-service core switch, new additions to the Group's range of photonics equipment, notably Ultra Long Haul and Metro DWDM product ranges as well as further development of the Group's SDH technology to produce a fourth generation SDH multiplexer. The Group also increased R&D investment in its Mobile businesses. R&D investment in a number of access product lines was scaled back during the year in line with the Group's strategy to focus spend on certain broadband access product lines, notably in fixed wireless access and the recently launched Access Hub. Expenditure on a number of narrowband access platforms was reduced and research programmes in areas such as fibre-in-the-loop and wireless-ip-in-the-local-loop ("WipLL") were terminated. OPERATING EXPENSES -- SELLING AND DISTRIBUTION EXPENSES Selling and distribution expenses (excluding joint ventures) reduced by L168 million to L590 million, representing 14 per cent. of sales in the year ended 31 March 2002 (2001: L758 million, 11 per cent. of sales). OPERATING EXPENSES -- ADJUSTED ADMINISTRATIVE EXPENSES Adjusted administrative expenses amounted to L308 million, or 7 per cent. of sales, a reduction in absolute spend of L73 million (2001: L381 million, 6 per cent. of sales). The majority of the cost savings achieved in this area during the year related to headcount reductions as well as the rationalisation of a number of sales offices around the world and the termination of a number of marketing programmes and initiatives. The disposal of businesses in the current and previous financial years also led to a reduction in selling and distribution and administrative costs during the year of L21 million. The relative increase in these costs as a percentage of sales was mainly the result of the severe downturn in sales volumes. OPERATING EXPENSES -- OTHER Other operating expenses amounted to L5 million during the financial year ended 31 March 2002 compared to other income of L74 million in the previous year. The Group recorded an increase in head office and other central costs which had been offset in the previous year by income from the sale of trademarks, settlement of a legal claim and the release of provisions no longer required against insurance-related liabilities. In addition, there was a charge of L11 million in respect of share incentive plans compared to a charge of L16 million in the previous year. 606

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- YEAR ENDED 31 MARCH 2002 COMPARED WITH YEAR ENDED 31 MARCH 2001 CORE BUSINESS REVIEW CORE KEY FIGURES <Table> <Caption> Year ended 31 March -------------- 2001 2002 ----- ----- in L million <S> <C> <C> Turnover 4,336 2,741 Adjusted gross profit 1,689 599 Adjusted operating profit/(loss) 529 (493) </Table> TURNOVER The Core business serves a strong global customer base of predominantly incumbent operators. The ten largest customers of Network Equipment and Network Services during the year were BT (UK), Bell South (USA), Metro City Carriers (Germany), Qwest (USA), SBC (USA), Sprint (USA), Telecom Italia (Italy), UK Ministry of Defence (UK), Verizon (USA), Vodafone-Omnitel (UK, Germany and Italy). This group of customers accounted for 37 per cent. of Core sales in 2002. BT remains the Group's largest customer and accounted for 14 per cent. of Core sales in 2002 (2001: 19 per cent.). CORE ADJUSTED OPERATING LOSS The Core businesses recorded an adjusted operating loss of L493 million during the year (2001: adjusted operating profit of L529 million). This substantial decline was driven by a significant drop in adjusted gross margins caused by the decline in sales volumes and the Group's inability to restructure its cost base sufficiently rapidly within the year to offset the speed of the sales decline. The operating performance year on year declined across all major product segments but was most marked in Network Equipment. ANALYSIS BY BUSINESS TYPE NETWORK EQUIPMENT: SALES In the year ended 31 March 2002, Network Equipment sales amounted to L1,804 million compared to L3,359 million in the previous year, a decline of L1,555 million or 46 per cent. Sales declined across all major product areas as a result of the general decline in demand for telecommunications equipment as the majority of telecom operators significantly reduced their capital spending budgets in order to focus on their own profitability and cash generation. Optical Networks In the year ended 31 March 2002, sales in this predominantly European business decreased by 47 per cent. to L737 million. The main factor contributing to this decline was the significant fall in sales of SDH equipment, which accounted for around 85 per cent. of total Optical Networks sales during the year ended 31 March 2002. SDH sales were predominantly focused on lower-capacity products as telecom operators sought to maximise utilisation in their existing networks rather than proceeding with the construction of new networks. Overall, the underlying decline was broadly in line with the overall industry trend in the SDH market, but was exacerbated by the phasing of capital expenditure of the Group's major incumbent customers. These telecommunication network operators decreased spend more rapidly and ahead of other operators. During the first half of the year, the six months ended 30 September 2001, Optical Networks sales decreased by 43 per cent. to L357 million compared to the first half of the 2001 financial year. The UK market was hardest hit, mainly due to the significant reduction in spending by UK second operators, although sales to BT, the Group's largest customer, were also down in the period. Sales of DWDM equipment were sustained at a comparable level to the second half of the previous financial year of over L50 million as these products continued to gain market acceptance following their launch one year previously. 607

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- During the second half of the year to 31 March 2002, Optical Networks sales decreased by 51 per cent. to L380 million compared to the second half of 2001 financial year. The continued decline in sales of SDH equipment was partially offset by increased sales of DWDM, which were a result of the first shipments of this type of equipment to Telecom Italia under the previously awarded exclusive five year frame contract, and a number of new customer frame contracts including Vodafone-Omnitel. In addition during this period, the Group made shipments of ultra-broadband DWDM equipment to BT under the existing five year frame contract. Given the nature of this contract, revenue relating to ultra-broadband products will be recognised when the circuits provided by this equipment are utilised. As none of the circuits provided by this equipment were utilised prior to 31 March 2002, no revenues associated with these shipments were recognised during the financial year. Adverse fluctuations in foreign exchange rates accounted for L9 million of the overall sales decrease in this product area. Access Systems Broadband access sales were flat at L145 million. Network operators, in particular, Bell South, deferred deployment of next-generation fibre solutions for economic reasons and instead rolled-out lower volumes of mature access products such as copper and digital loop carriers, leading to lower sales levels in these areas. Increasing sales of the Group's Access Hub products and broadband point-to-point radio systems, particularly to German mobile operators for use in 2.5G and 3G networks, offset these decreases. First sales of Access Hubs were also made to Telecom Italia and Telkom South Africa during the year. Sales in mature access were down equally across OPP, narrowband access products and voice systems. OPP sales were down to L247 million compared to L465 million in the previous year as the result of the general slowdown in the market for equipment, primarily in the United States and Mexico, particularly as a result of the rapid decline in the North American emerging carrier market. Sales of other mature access products, including our copper and fibre-based DISC*S access platform decreased during the first half as a result of capital expenditure reductions amongst North American incumbent local carriers, particularly Bell South and Sprint. In voice systems, a predominantly UK-based business, sales declined because previously awarded contracts reached completion and were not replaced by new contracts as customers refocused investment away from narrowband switching installed bases. BBRS BBRS sales decreased by L218 million or 51 per cent. to L209 million for the year ended 31 March 2002. During the first half of the year, sales decreased by 53 per cent. to L113 million and during the second half, sales decreased by 49 per cent. to L96 million. Sales decreased in all major geographic zones. Overall, two main factors contributed to the sales decline. Sales to enterprise customers declined substantially in the period, although the US Federal Government remained the largest single customer of the Group's broadband switching equipment. This trend reflected the continued impact of the Group's actions, commenced during the previous financial year, to focus its technical and commercial resources within the BBRS Business towards customers requiring carrier-class networks, namely telecommunications service providers and selected enterprise customers such as governments and armed forces who require more resilient switching capacity. Sales to US service providers decreased during the year. Sales to BBRS' traditional service provider customer base of CLECs and Internet Service Providers ("ISPs") declined as they reduced their capital spending and were not replaced as rapidly as the Group had anticipated by sales to established operators due to capital spending restrictions and the consequent absence of major new contract wins. In addition, the Group has historically sold a third party's broadband switching equipment into the UK market under an original equipment manufacturer's ("OEM") distribution agreement. Sales under this agreement declined during the year as a result of reduced customer spending in the UK market and the impact of the pending termination of this contract during the first half of the financial year ending 31 March 2002. 608

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- During the first half of the year, the Group made initial shipments of its new MPLS products and during the second half, the Group's new multi-service core switch, the BXR 48000, was successfully launched and shipped to the US Federal Government and BTexact Technologies for field trials. NETWORK EQUIPMENT: ADJUSTED OPERATING LOSS Network Equipment incurred an adjusted operating loss of L464 million during the year, a decline of L906 million, or 205 per cent., for the year ended 31 March 2002 (2001: adjusted operating profit L442 million). Adjusted operating margins fell to negative 26 per cent. (2001: positive 13 per cent.). This decline was driven by the substantially reduced adjusted gross margin. This resulted from the decline in sales recorded during the year, which led to under-recovery of costs in the supply chain. Contractual annual price reductions under existing frame contracts, some price erosion on new Optical Networks orders and an unfavourable business mix also contributed to the decline, but to a much lesser extent. The decline in adjusted operating profit during the first half of the year was mainly due to the significantly reduced sales volumes and the inability of the Group to adjust its cost base sufficiently rapidly in reaction to this decline. The reduced sales volumes led to under-utilisation of assets in the supply chain and manufacturing processes, which the Group addressed and continues to address through its cost reduction strategy put in place as a result of the operational review announced in September 2001. Adjusted gross margins were also impacted by an adverse change in business mix, with the decline of sales of broadband switching and certain narrowband access products, which have historically achieved higher than average adjusted gross margins. Adjusted operating losses increased during the second half impacted by the continuing reduction in sales volumes as well as some price erosion on certain new contracts, previously agreed contractual price reductions offered to customers under existing frame contracts which the Group was unable to offset with corresponding product cost reductions and the continuing change in business mix away from higher margin products. Also, during the second half, the Group incurred a number of one-off marketing costs to terminate previously committed marketing activities and programmes in order to achieve longer-term cost savings. R&D costs also increased, particularly in the final quarter of the year, as a result of the development and launch of key products including the BXR 48000 and new additions to the Group's range of DWDM products, notably Ultra Long Haul and Metro DWDM product ranges as well as further development of SDH technology to produce a more cost effective fourth generation SDH multiplexer. This increase was partially offset by the scaling back of the Group's access systems business to focus more on broadband access product lines, notably in fixed wireless and the recently launched Access Hub high density DSLAM platform. NETWORK SERVICES: SALES Sales of Network Services decreased by L47 million, or 5 per cent., to L969 million for the year ended 31 March 2002 (2001: L1,016 million). Excluding the impact of acquisitions completed since 1 April 2000, such as MSI, APT and Northwood Technologies, Network Services sales decreased by 7 per cent. The main driver of this decline was a fall in sales of installation and commissioning services following the downturn in Network Equipment supply. IC&M IC&M sales decreased by 20 per cent. to L528 million during the year ended 31 March 2002. The decrease in installation and commissioning activities relating to Group products reflected the lower volume of Network Equipment sales. The decrease was partially offset by an increase in demand for cable installation in the UK, as well as maintenance services world-wide, as network operators sought to maximise the utilisation of their existing networks in order to reduce capital expenditure. VAS VAS sales increased by 15 per cent. to L414 million during the year ended 31 March 2002. Excluding the impact of acquisitions, sales increased by 14 per cent. The major driver of this growth related to the Group's project-based Integrated Systems activity which serves non-telecom industry sectors such as government and 609

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- transportation. In particular, sales grew in the UK due to the conclusion of the London Underground Jubilee Line extension contract, as well as in the Middle East. During the first half of the year, sales of Wireless Services grew substantially driven by the increased difficulty for operators to secure new radio sites and increased demand for wireless network planning consultancy services as operators maximised efficiency in their existing networks and began to plan the roll out of 2.5G and 3G networks. This growth was not sustained in the second half of the year however as a result of delayed 3G network rollouts, leading to relatively flat sales of Wireless Services for the year as a whole. NETWORK SERVICES: ADJUSTED OPERATING PROFIT Network Services adjusted operating profit decreased by L67 million, or 66 per cent., to L35 million for the year ended 31 March 2002 (2001: L102 million). Adjusted operating margins fell to 3.6 per cent. from 10 per cent. in the previous year. Adjusted operating profit fell across all service activities, but the level of decline was most substantial in IC&M. This labour-intensive activity saw significant sales growth in the year ended 31 March 2001 and the operating cost base, in particular the workforce, was geared up to deal with demand at that time. During the year ended 31 March 2002, demand for installation and commissioning activities dropped quarter on quarter following lower Network Equipment supply orders and this led to under-utilisation of resources in this area. The Group was unable to reduce costs quickly enough, particularly during the first half of the financial year, to prevent operating margin erosion. During the second half, the business began to benefit from the savings achieved as a result of the Group's cost reduction initiatives, but these were not sufficient to compensate for the continued decline of Network Equipment sales. The delay in the deployment of 3G networks by mobile operators, particularly in the UK, and the change in business mix in the US resulting in a higher proportion of software sales but a decline in consulting services, also led to the under-utilisation of resources in the VAS business. CAPITAL During the year ended 31 March 2002, Capital sales amounted to L422 million, a decrease of L157 million, or approximately 27 per cent., compared to sales of L579 million in the previous year. Of this decrease, the disposal of certain businesses within the year accounted for a L44 million decrease, while the non-recurrence of sales by businesses disposed in the year ended 31 March 2001 accounted for a further L84 million decrease. The remaining decrease was accounted for in other elements of the Capital business. In February 2002, the Group completed the disposal of the Marconi Optical Components business to Bookham Technology plc in exchange for approximately 9 per cent. of the new enlarged issued share capital of Bookham Technology plc. GROUP REVIEW -- OTHER FINANCIAL ITEMS YEAR ENDED 31 MARCH 2002 COMPARED WITH YEAR ENDED 31 MARCH 2001 EXCEPTIONAL ITEMS OPERATING EXCEPTIONALS For the year to 31 March 2002, exceptional items charged to Group operating loss (excluding joint ventures and associates) totalled L5,210 million. Of this amount, L830 million was charged against gross profit and L4,380 million against operating expenses. This had the effect of reducing the Group's gross profit (excluding share of joint venture gross profit) to L227 million and increasing the Group's operating loss to L6,115 million. This was made up of a L3,831 million charge to write-down goodwill and tangible fixed assets, a L672 million increase in provisions for slow-moving and obsolete stock and related charges, restructuring and reorganisation charges totalling L482 million relating to the Group's on-going rationalisation programme including charges for headcount reductions, and exceptional IT spend of L75 million. There was also a charge of L150 million to increase doubtful debt provisions (of which L148 million was charged during the first half and a further L2 million during the second half). 610

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Goodwill and tangible fixed asset write-down The carrying values of goodwill and tangible fixed assets were assessed in the year to 31 March 2002. This assessment was undertaken in line with the Group's accounting policies and in the light of the declining industry and economic trends prevalent during the year. The assessment measured the amount by which the carrying values of the goodwill and tangible fixed assets exceeded the present value of expected future cash flows from operations. The declining industry and economic trends and more conservative assessment of future growth prospects of acquired businesses led to Corp's decision to write down the value of historical goodwill and tangible fixed assets by L3,831 million (of which L3,493 million was charged during the first half of the year and L338 million during the second half). This charge comprises L3,677 million to write-off purchased goodwill and L154 million for the impairment of tangible fixed assets. The L3,677 million impairment charge in the year was predominantly against FORE Systems (L1,980 million), RELTEC Corporation (L748 million), MSI (L353 million) and Mariposa Technologies, Inc. (L166 million). The remaining L430 million was against several other acquisitions completed in previous years. Stock provisions For the year ended 31 March 2002, the Group increased provisions for slow-moving and obsolete stock and related charges by L672 million. Of this total amount, L518 million was charged during the first half of the year and L154 million during the second half. The decision to record these charges was made as a consequence of the more uncertain sales outlook, predominantly in relation to optical networking products as well as the Group's decision to scale-back certain product lines. L91 million of the total charge related to charges for onerous supplier commitments, of which L51 million was paid out during the year. Restructuring and reorganisation charges During the year ended 31 March 2002, the Group incurred an exceptional charge of L482 million (L342 million during the first half and L140 million in the second half) mainly in relation to the actions and initiatives undertaken to restructure and reorganise the Group operationally as a result of the sudden and significant downturn in trading in the global telecommunications markets. L127 million of the total represented additional costs incurred as a consequence of the Group's decision to outsource certain manufacturing operations to Jabil Circuit, Inc. Under the terms of the agreement, the Group made payments of L77 million during the financial year, provided L19 million against stock with L31 million expected to be paid in the future. This was charged to gross profit as part of the overall charge of L830 million. L31 million of the total charge was taken in respect of onerous contracts and represents certain liabilities to which the Group is committed as a result of the operational restructuring. This included liabilities relating to equipment leasing contracts and supply contracts under which the Group had previously agreed to purchase minimum volumes of goods and services which will offer no economic value to the business as a result of its reduced size. This was also charged to gross profit as part of the overall charge of L830 million. Restructuring costs relating to employee severance associated, in particular, with voluntary redundancy payments for approximately 10,000 employees amounted to L239 million during the financial year. The Group made cash payments of L207 million during the year. The balance of L30 million accrued at 31 March 2002 was to cover severance payments to approximately 700 employees, predominantly in the UK and Germany, who had volunteered for redundancy prior to the year end but whose leaving dates fall in the current financial year to 31 March 2003. A charge of L40 million was taken in respect to site rationalisation and reflected the costs associated with the closure and consolidation of various Group sites around the world. Other restructuring costs of L45 million related to various other costs and contractual commitments associated with the Group's restructuring programme. 611

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Other exceptional items During the financial year, the Group planned and began to implement a new global IT system. In the light of the revised trading outlook and the Group's continued focus on cost reduction, the systems implementation was terminated. L75 million of the total charges for restructuring and reorganisation represented costs associated with other systems implementation and related costs, L43 million in relation to capitalised external consultancy costs, L24 million of hardware and software costs expensed during the year and L8 million of other associated project costs. NON-OPERATING EXCEPTIONALS The Group incurred non-operating exceptional charges of L638 million during the year ended 31 March 2002. Gain on disposal of subsidiaries and other fixed assets During the year ended 31 March 2002, the Group recorded an overall net gain of L347 million in relation to gains on disposal of subsidiaries and other fixed assets and investments. L358 million of this gain related to the disposal of the discontinued operations Medical Systems, Data Systems and Commerce Systems. The Group's continuing operations incurred a net loss of L11 million on the disposal of fixed assets and investments. Gains on disposals of property and the Group's investments in Lottomattica S.p.A., GDA, Siemens Telecommunications Pty Limited and other assets and investments amounted to L189 million. This was more than offset by losses on the sale of the Marconi Optical Components business and write-downs on the value of some of the Group's investments, including NetDecisions Holdings Limited, Easynet Group Plc and Atlantic Telecom Group Plc. Release of provisions relating to share options At the time of the demerger of the Group's defence and electronics business to BAE SYSTEMS plc (formerly British Aerospace plc), the Group set up a non-operating profit and loss account provision of L633 million relating to share option schemes, L7 million of which was utilised in prior years. L247 million was recorded in shares to be issued within equity shareholders' funds and L386 million within provisions. At 31 March 2002, L291 million of this provision had been released as a non-operating exceptional item, reflecting the Group's view that the market price of its shares will not reach the trigger price of the options within the specified timeframes. L247 million of the release related to the Marconi Launch Share Plan and L44 million to other share option schemes. At 31 March 2002, gross provisions of L374 million remained on the balance sheet to cover the Group's share hedging arrangements. Collateral payments of L214 million made during the year were offset against this amount. INTEREST AND FINANCE INCOME In the twelve months to 31 March 2002, the Group's net interest charge was L244 million (2001: L150 million). The interest charge increased as a function of the Group's higher net debt position. In the year to 31 March 2002, net finance income fell to L34 million from L41 million in the previous year. TAXATION The tax credit on ordinary activities before goodwill amortisation and exceptional items was L21 million in the reporting period, compared with a charge of L195 million in the corresponding period in the prior year. The net tax charge on exceptional items was L231 million. The Group paid L13 million in relation to tax, after hedging. This comprised L110 million net tax repayments, offset by payments of L123 million related to tax on foreign exchange rate movements. For the year ended 31 March 2001, the comparable amounts were L137 million of tax payments and L33 million of receipts related to tax on foreign exchange rate movements. 612

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Deferred tax assets of L596 million (2001: L147 million) were not recognised in respect of operating losses, pension scheme deficits and exceptional expenditure as the Group was not sufficiently certain that it would be able to recover those assets within a relatively short period of time. GOODWILL AMORTISATION The total Group goodwill amortisation charge for the year decreased to L433 million (2001: L673 million) of which L350 million was incurred in the first half and L83 million in the second half. This decrease is a result of the reduced carrying value of goodwill following the exceptional goodwill impairment discussed under "Goodwill and tangible fixed asset write-down" above. EARNINGS PER SHARE Basic and diluted loss per share, which reflects goodwill amortisation and exceptional items, was 607.6 pence (2001: 27.5 pence). The loss per share excluding exceptional items and goodwill amortisation was 65.4 pence compared to earnings per share of 45.6 pence in 2001. 31 MARCH 2002 -- FINANCIAL CONDITION BALANCE SHEET As at 31 March 2002, net liabilities before net retirement benefit deficits stood at L1,890 million compared to net assets before net retirement benefit surpluses of L4,314 million at 31 March 2001. The main contributing factor to this decrease was the write-down of goodwill and other operating and non-operating exceptional items, offset by the release of provisions for shares to be issued and the gains on disposals of businesses, investments, land, property and other assets; as discussed above. Other contributing factors included the Group's operating loss, interest costs and currency movements. NET (LIABILITIES)/ASSETS As at 31 March 2002, the Group had net current liabilities of L756 million, including drawings of approximately L2.2 billion under the Group's bank credit facility which has been placed on demand in the context of the Group's proposed Restructuring, and around L260 million drawn under bilateral arrangements. WORKING CAPITAL Stocks and contracts in progress reduced by approximately L1 billion during the year ended 31 March 2002. Of this amount, approximately L760 million related to the Core businesses and L230 million to discontinued operations. In the Core, stocks and contracts in progress were reduced by approximately L520 million as a result of net provision movements. The balance of the reduction was achieved through normal trading following the Group's improved management of the supply chain process and better integrated planning between sales and operations. Group debtors decreased by approximately L1.2 billion during the year ended 31 March 2002. Of this amount, approximately L710 million related to the Core businesses and L430 million to discontinued operations. In the Core businesses, the main driver of the reduction in debtors was the reduced trading volumes experienced during the year. Net debtor provision movements accounted for approximately L107 million. During the first half of the year, debtor days in the Core businesses increased from 89 days net at 31 March 2001 to 104 days net at 30 September 2001. This was mainly the result of difficult trading conditions. During the second half, the Group focused on cash collection and made significant improvements in the management of overdue debts, leading to a reduction in Core debtor days to 103 days net (excluding the impact of the one-off sale of SDH inventory to BT) by March 2002. The increase year on year was due to the negative impact of a higher proportion of Southern European sales, where payment terms are typically longer. Trade, other creditors and accruals reduced by approximately L1.0 billion during the year ended 31 March 2002. Of this reduction, approximately L350 million related to the Core businesses and L350 million to discontinued 613

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- operations. The balance related to non-Core activities and other business disposals not considered discontinued operations. The reduction in the Core businesses was mainly due to the reduced trading volumes experienced during the year. Creditor days in the Core businesses reduced to 54 days (after adjusting for the exclusion of the one-off impact of the sale of SDH inventory to BT in the final quarter of the year ended 31 March 2002) at 31 March 2002 from 64 days at 31 March 2001. This was mainly due to the increased proportion of outsourced manufacturing in Europe and North America, where payment terms stand at 30 days. PROVISIONS Provisions for liabilities and charges decreased by L209 million to L505 million at 31 March 2002. Of the decrease, L263 million related to movements in share option provisions, L214 million of which was in respect of cash paid to collateralise the Group's obligations under share hedging arrangements and L44 million to the release of provisions, accounted for as a non-operating exceptional item. The balance of the movement related to L31 million of provisions utilised or released against share options issued to employees at the time of previous acquisitions, offset by accrued interest on the Group's share hedging arrangements and other charges of L26 million. Reorganisation and restructuring provisions increased, after amounts spent in the period, by a net L50 million. Other provisions decreased by a net L14 million. The majority of the Group's rationalisation programmes were treated on a cash basis, with costs charged to the profit and loss account as the cost was incurred. However, provisions for restructuring were created to cover those parts of the Group's rationalisation programme, mainly in Germany and the UK, where as at 31 March 2002, individuals had been identified to leave the Group during the course of the current financial year. VENDOR FINANCE As at 31 March 2002, the Group had vendor finance commitments of approximately L100 million ($142 million), of which L58 million ($82 million) had been drawn. In addition, the Group provided a $90 million (L63 million) counter-indemnity to Koninklijke Philips Electronics N.V. relating to the sale of Marconi Medical Systems, Inc. Approximately L29 million was paid out against this indemnity during the year to 31 March 2002. Management does not intend to extend any significant further financing using the Group's own funds. Instead, through its in-house vendor finance specialists, it will continue to provide innovative and structured financing solutions for its customers through third party financing institutions. NET DEBT Net debt at 31 March 2002 was reduced to L3,335 million from L3,782 million at 31 March 2001. At 31 March 2002, net debt comprised cash and liquid resources of L1,361 million, gross debt of L4,696 million, and net L81 million (2001: L474 million) owed to plc and subsidiaries of plc. The gross debt at 31 March 2002 included L2.1 billion in Bonds (2001: L2.2 billion) with a principal of $1.8 billion, and approximately L260 million in drawings under local bilateral bank agreements. YEAR ENDED 31 MARCH 2002 -- CASH FLOW ADJUSTED OPERATING CASH FLOW After capital expenditure of L361 million (2001: L578 million), the Group incurred an adjusted operating cash outflow of L351 million for the year ended March 2002 (2001: L645 million). This was predominantly driven by the Group's adjusted operating loss of L463 million, offset by an improvement in working capital of L239 million. Following a L533 million cash outflow after capital expenditure during the first half of the year, the Group generated positive operating cash flow of L182 million during the second half. This excluded proceeds of L116 million from the sale of properties. This sequential improvement resulted mainly from the Group's increased focus on cash collection from debtors and improved management of overdue debt, as well as from increased utilisation of inventory. 614

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- CAPITAL EXPENDITURE AND FINANCIAL INVESTMENT Net capital expenditure and financial investment amounted to L196 million for the year ended 31 March 2002. Total capital expenditure in the Group decreased by L217 million, or 38 per cent., to L361 million for the year ended 31 March 2002. In line with the Group's strategy of reducing capital expenditure to the level of depreciation, capital expenditure in the Core businesses decreased during the year. The main focus of this expenditure related to equipment for participation in technology trials with key customers and test equipment which supports on going research and development activity, the purchase of software licences as part of the Group's planned implementation of a new IT system and expenditure related to site and facility developments. The software licences were subsequently written off as the implementation of the IT project was terminated. Financial investments represented a net cash outflow of L8 million and included L214 million of collateral payments paid under the Group's share option related hedging arrangements, L24 million repurchase of shares to satisfy the Group's obligations under option schemes relating to various previously acquired companies, and other fixed asset investments of approximately L70 million, including the Group's investment in Confirmant Limited, a joint venture with Oxford GlycoSciences. This was offset by some L320 million proceeds from the sale of the Group's remaining interests in Alstom SA and other smaller financial investments, including Lagardere SCA and Lottomatica S.p.A. ACQUISITIONS AND DISPOSALS Net cash inflows relating to acquisitions and disposals amounted to L995 million for the year ended 31 March 2002. This comprised approximately L1.4 billion net cash proceeds from the disposal of businesses, including Marconi Medical Systems, Inc., Marconi Commerce Systems Group and Marconi Data Systems Group, and the Group's 50 per cent. stake in GDA, which were offset by cash outflows relating to the demerger of ipsaris Limited into Easynet Group Plc, the creation of Ultramast Limited, a joint venture with Railtrack Telecom Services Limited and other smaller acquisitions. EXCEPTIONAL CASH FLOWS The Group incurred operating exceptional cash costs of L368 million during the year, related mainly to restructuring and rationalisation, including costs associated with the Group's manufacturing outsourcing programme, and the implementation of a new information technology system (which was subsequently terminated). Other cash flows relate primarily to interest, dividends and tax. 615

(2000: 83 per cent.) of these sales were in Network Equipment and 23 per cent. (2000: 17 per cent.) in Network Services. Capital sales fell by L158 million, or 21 per cent., to L579 million for the year ended 31 March 2001 (2000: L737 million) due principally to the disposals of Avery Berkel and parts of the Group's Marconi Software Solutions business. DISCONTINUED OPERATIONS Sales in discontinued operations increased by L156 million, or 8 per cent., to L2,027 million (2000: L1,871 million).

The increase in revenues in the UK (up by L271 million) and Rest of Europe (up by L443 million) in the year to 31 March 2001 compared to the year to 31 March 2000, was primarily the result of like-for-like increases in sales of optical networks and network services products and the effect of acquisitions, principally the full-year effect of the acquisition of the public networks business of Bosch. 616

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- GROUP ADJUSTED OPERATING PROFIT/(LOSS) BY SEGMENT <Table> <Caption> Year ended 31 March ------------ 2000 2001 ---- ---- in L million <S> <C> <C> Network Equipment 415 442 Network Services 71 102 Other (including intra-activity sales) (23) (15) ---- ---- Core 463 529 Capital 56 1 ---- ---- Continuing Operations 519 530 Discontinued Operations 210 224 ---- ---- Group 729 754 ==== ==== </Table> The Group generated an adjusted operating profit of L754 million, comprising an adjusted operating profit of L530 million contributed by its continuing operations and an adjusted operating profit of L224 million by its discontinued operations. This compares to a Group adjusted operating profit of L729 million in the year ended 31 March 2000. Continuing Operations Core adjusted operating profit amounted to L529 million, an increase of L66 million, or 14 per cent., compared to an adjusted operating profit of L463 million recorded in the previous year. Adjusted operating profit in the Network Equipment business increased in the Group's optical networks and access systems equipment businesses, mainly as a result of the increase in revenues. Within the Group's broadband switching and other networks businesses, adjusted operating profit was reduced by a number of factors: a reduction in like-for-like revenues, increased expenditure in the areas of selling, marketing and global advertising and an increase in the level of research and development expenditure. In the Network Services business, adjusted operating profit increased due to growth in like-for-like revenues, offset in part by higher overheads to support the rapid expansion. Adjusted operating profit in the Capital business decreased as the result of the disposal of businesses and the decreased profit performance of the division's emerging and mature businesses. Discontinued Operations Adjusted operating profit in discontinued operations increased by L14 million or by 7 per cent. to L224 million (2000: L210 million). SEGMENTAL ANALYSIS Network Equipment In the year ended 31 March 2001, Network Equipment sales amounted to L3,359 million, an increase of L776 million, or 30 per cent., compared to sales of L2,583 million recorded in the previous year. Sales increased across all major product areas and was particularly marked in Optical Networks and in the Group's Access businesses as telecom operators increased their spending on these types of equipment to augment the capacity of their existing networks or to deploy new networks. In Optical Networks, sales growth was driven mainly by increased volumes of SDH products, particularly in the UK, as well as initial shipments to European customers of the Group's new range of DWDM products, which was launched during the first half of the year. Increased sales in the Group's access businesses was driven by increased volumes of OPP equipment in the US and fixed wireless access products in Europe. Sales of broadband switching equipment remained flat as a result of the 617

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- combination of reduced sales to enterprise customers, offset by the full year effect of the acquisition of FORE Systems in the previous year and a foreign exchange translation gain due to the strengthening of the US dollar against sterling. Network Equipment adjusted operating profit increased by L27 million, or 7 per cent., to L442 million for the year ended 31 March 2001. Adjusted operating margins fell to 13 per cent. from 16 per cent. The decline in adjusted operating margins was due to the higher level of R&D expenditure funded directly by the Group as a percentage of sales and increased selling and marketing expenditure as a percentage of sales. Network Services Network Services sales increased by L473 million, or 87 per cent., to L1,016 million in the year ended 31 March 2001. The effect of the acquisitions of MSI, APT and SMS completed during the year and the full year effect of the acquisition of Bosch Public Networks in the previous year accounted for L201 million of this sales growth. Excluding the effect of these acquisitions, sales growth was driven primarily by higher demand for network planning and build services from European incumbent operators. A number of new contracts were won during the year including a contract for the design, installation and maintenance of communications for the West Coast Main Line in the UK, a contract for electronic traffic monitoring and control for Texas Department of Transportation and network design and configuration services for North Kansas City Hospital, both in the US. In addition, during the period, the Group entered the market for managed services with contracts for BT Ignite Nederland and Jersey Telecom. Adjusted operating profit in Network Services increased by L31 million, or 44 per cent., to L102 million for the year ended 31 March 2001 (2000: L71 million). Adjusted operating margins decreased to 10 per cent. (2000: 13.1 per cent.). The increase in Network Services' adjusted operating profit was due to the increased sales in this segment, partially off-set by higher overheads to support the rapid expansion of the Group's service activities. The acquisition of businesses with lower adjusted operating profit margins led to the erosion of the margin in the period. YEAR ENDED 31 MARCH 2001 COMPARED WITH YEAR ENDED 31 MARCH 2000 GROUP REVIEW -- OTHER FINANCIAL ITEMS EXCEPTIONAL ITEMS OPERATING EXCEPTIONALS In the year ended 31 March 2001, the Group incurred net restructuring and reorganisation costs of L32 million relating to a charge for voluntary redundancy schemes and one-off restructuring costs of L65 million, partially offset by favourable settlements of contract commitments of L33 million. NON-OPERATING EXCEPTIONALS Gains on disposals of subsidiaries and other fixed asset investments of L89 million included the disposal of part of the Alstom Holding, Avery Berkel Group and Woods Air Movement. Amounts written off investments of L110 million related to the reduced market valuations of fixed asset investments. Other separation receipts of L20 million represented a further settlement received in relation to the MES transaction in the year. INTEREST AND FINANCE INCOME Net finance income increased from L32 million to L41 million or by 28 per cent. TAXATION The tax charge on loss on ordinary activities before goodwill amortisation and exceptional items amounted to L195 million (2000: L196 million). The net charge on goodwill amortisation and exceptional items was 618

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- L17 million, compared to a credit of L198 million in the prior year that crystallised as a result of the MES Transaction. The Group paid L137 million in relation to tax, compared to L114 million in the year ended 31 March 2000. L74 million (2000: L111 million) was paid in the UK and L63 million (2000: L3 million) overseas. Deferred tax assets of L147 million (2000: L166 million) were not recognised in respect of operating losses, retirement benefit scheme deficits and exceptional expenditure as the Group was not sufficiently certain that it would be able to recover those assets within a relatively short period of time. GOODWILL AMORTISATION Goodwill amortisation reduced from L765 million to L673 million or by 12 per cent. This was due primarily to the one-off impact in the year ended March 2000 of writing off in-process research and development arising in the newly acquired FORE Systems and RELTEC Corporation. EARNINGS/(LOSS) PER SHARE Basic and diluted loss per share, which reflects goodwill amortisation and exceptional items, was 27.5 pence (2000: earnings per share of 56.8 pence). Earnings per share excluding exceptional items and goodwill amortisation was 45.6 pence compared to earnings per share of 49.7 pence in the prior year. 31 MARCH 2001 -- FINANCIAL CONDITION NET ASSETS As at 31 March 2001, the Group had net assets before net retirement benefit surpluses of L4,314 million, compared to L4,420 million at 31 March 2000. During the period, there was a L1 billion increase in the value of goodwill, largely due to the Group's acquisitions, which included MSI, Mariposa Technology, Inc., Systems Management Specialists, Inc., Splice Transmissao S.A. and Albany Partnership Limited, and a L0.8 billion increase in the value of stocks and contracts in progress. These increases were offset by an approximately L1 billion reduction in fixed asset investments, predominantly due to the flotation of Alstom, the disposal of part of the Group's investment in Lagardere SCA, the write-down of the Group's investment in Atlantic Telecom Group plc, and an approximately L1.1 billion increase in the Group's net debt balance. WORKING CAPITAL Stocks and contracts in progress increased by L775 million during the year ended 31 March 2001. Of this increase, the majority related to the Core businesses, with the balance being attributable to discontinued operations. Within the Core businesses, the increase in the levels of stock was in response to the significant increase in sales volumes experienced in the year to 31 March 2001 which, at the time, was expected to continue into the following financial year. Group debtors increased by approximately L532 million during the year ended 31 March 2001. The majority of this increase related to the Core businesses, with the balance being attributable to discontinued operations. The increase in debtors in the Core businesses was due predominantly to the increase in sales experienced during the period. Trade, other creditors and accruals increased by approximately L370 million during the year ended 31 March 2001. Of this increase, the majority related to disposed and discontinued operations, with the remainder relating to the Core businesses. 619

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- PROVISIONS Provisions for liabilities and charges increased by L21 million to L714 million during the year ended 31 March 2001. The slight increase in the provisions balance was the result of a L46 million increase in share option provisions, which was partially offset by a reduction in the reorganisation and restructuring and other provisions. The L46 million increase in the share option provision was primarily the result of issuing share options in respect of businesses acquired during the period, including MSI and Mariposa Technology, Inc. NET DEBT Net debt increased by L1,089 million to L3,782 million in the year to 31 March 2001. At 31 March 2001, net debt comprised cash and liquid resources of L369 million (2000: L624 million), gross debt of L3,677 million (2000: L3,317 million) including amounts owing to plc and subsidiaries of plc which are not subsidiaries of Corp, of L474 million (2000: L548 million). The gross debt at 31 March 2001 included L2.2 billion in Bonds (2000: L894 million), which represented an increase on the previous financial year following the issue of two unsecured US dollar bonds with principal amounts of $1.8 billion and L1,014 million of drawings under the E7 billion multi-currency revolving syndicated credit facilities. As a result of the movement in foreign exchange rates from 31 March 2000 to 31 March 2001, the value of net debt increased by L256 million in the year. CASH FLOW ADJUSTED OPERATING CASH FLOW After capital expenditure of L578 million (2000: L305 million), the Group incurred an adjusted operating cash outflow of L645 million (2000: L411 million inflow). The reduction was due to the increase in working capital, particularly in stock and debtors, and the increase in capital expenditure, which was largely a result of the growth of the business. The increase in inventory was a result of the build-up of optical components in advance of scheduled new product deployments and the expected increased sales volumes in the 2002 financial year. ACQUISITIONS AND DISPOSALS Cash outflows related to acquisitions and disposals, including the non-operating exceptional cash flows related to the merger/demerger of MES, decreased from L3,974 million in the year ended 31 March 2000 to L658 million in the year ended 31 March 2001. In the year ended 31 March 2001 the outflow of L658 million was due to the various acquisitions made during the year, including MSI, Mariposa Technology, Inc., Systems Management Specialists and Albany Partnership Limited, with a further L56 million representing further settlements of the amounts in respect of the merger/demerger of GEC's defence business with BAE SYSTEMS plc (the "MES Transaction") in March 2000. In the year ended 31 March 2000, the outflow of L3,974 million was largely due to our acquisitions of FORE Systems and RELTEC Corporation, along with relatively smaller outflows in respect of the Bosch Public Networks Division and the SDH and DWDM manufacturing business of Nokia. This was offset by a L1,386 million inflow in relation to the MES Transaction, which represented dividends and other cash receipts from those businesses separated. CAPITAL EXPENDITURE AND FINANCIAL INVESTMENT Net capital expenditure and financial investment for the year was an outflow of L34 million compared to an outflow of L394 million in the year ended 31 March 2000. Total capital expenditure in the Group increased by L273 million, or 89.5 per cent., to L578 million for the year ended 31 March 2001. 620

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 5: CORP'S DISCUSSION AND ANALYSIS OF ITS FINANCIAL CONDITION AND RESULTS OF OPERATIONS -------------------------------------------------------------------------------- Net financial investment amounted to L527 million of which L629 million was realised on the disposal of part of the Group's stake in Alstom, which was offset by the purchase of NetDecisions and other smaller investments. DIVIDENDS The Group paid no dividends in the year to 31 March 2001 compared to L349 million in the year to 31 March 2000. This outflow was paid out to fellow subsidiaries of plc outside the Corp Group. Other cash flows related primarily to tax and interest. 621

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 6 INSOLVENCY ANALYSIS 1.1 PURPOSE OF THE INSOLVENCY ANALYSIS The purpose of this Appendix is to assist Scheme Creditors of either Corp and/or plc in determining whether to accept the proposals set out in the Explanatory Statement. The insolvency analysis sets out a comparison between the position that would be likely to face Scheme Creditors if plc and Corp were to go into administration as at 30 April 2003 and the position under the proposed Schemes, to enable Scheme Creditors to decide whether to vote in favour of the proposed Schemes. Each Scheme Creditor must make up its own mind whether the Relevant Scheme operates to its benefit. Each Scheme Creditor should, in particular, consider whether the certain and immediate payment (in the form of cash, notes and equity) that it might receive under the Relevant Scheme would be better than a dividend arising from an administration or liquidation of plc or Corp. Scheme Creditors are invited to read carefully the significant limitations and uncertainties set out in section 1.5 below. 1.2 WHY VOTE FOR THE SCHEMES? If the Restructuring is not approved, the nature of the Group's financial position is such that Corp and plc would have no reasonable prospect of avoiding insolvency proceedings. Corp and plc strongly believe that, given the Group's financial position, the proposed Restructuring is in the best interests of all stakeholders, including Scheme Creditors and plc Shareholders. A KEY BENEFIT OF THE SCHEMES IS TO AVOID THE SERIOUS AND INEVITABLE UNCERTAINTY AND DELAY WHICH WOULD ARISE IN INSOLVENCY PROCEEDINGS FOR BOTH UNSECURED CREDITORS AND SECURED CREDITORS (ASSUMING THE INTERIM SECURITY HAS NOT BEEN RELEASED). CORP AND PLC BELIEVE THAT THE SCHEMES ARE MORE BENEFICIAL TO SCHEME CREDITORS THAN AN INSOLVENCY PROCEEDING OR ENFORCEMENT OF SECURITY AND SHOULD RESULT IN A BETTER RETURN, GREATER CERTAINTY AND AN IMMEDIATE DAY ONE DISTRIBUTION TO SCHEME CREDITORS. NONE OF THESE BENEFITS WOULD BE POSSIBLE UNDER THE INSOLVENCY ALTERNATIVES. 1.3 WHAT HAPPENS IF THE SCHEMES ARE APPROVED AND BECOME EFFECTIVE? If the Schemes are approved and become effective, each Scheme Creditor that participates in the First Initial Distribution will be entitled to receive for each L1,000,000 of Admitted Scheme Claim, an Initial Distribution of cash, New Notes and New Shares of approximately the amounts set out in Table 1 below: 622

The final calculations will be made at the Scheme Rate (which will be set five Business Days before the Effective Date). CASH The cash element of the distribution will be increased by the net proceeds of any asset disposals, other than up to L82 million of excluded asset disposal proceeds, received on or after 1 December 2002 and before 1 May 2003. The aggregate principal amount of the New Junior Notes will be decreased by 10/11ths of the sterling amount by which the cash element is increased. NEW NOTES The New Senior Notes will bear interest from their issue date at a per annum rate of 8 per cent. payable quarterly in cash on each 15 January, 15 April, 15 July and 15 October, commencing 15 July 2003. The New Junior Notes will bear interest from their issue date at a per annum rate of 10 per cent. payable quarterly in cash or, at Corp's option, at a per annum rate of 12 per cent. payable quarterly in kind (by issuing additional New Junior Notes to the holders of New Junior Notes) on each 31 January, 30 April, 31 July and 31 October, commencing 31 July 2003. On the first interest payment date for the New Notes, Corp will pay, in addition to accrued interest on the outstanding principal amount of the New Notes, an amount per New Note equal to the amount of interest that would have been accrued on New Notes if the New Notes had been outstanding for the period from 1 May 2003 to the issue date of the New Notes. All of the outstanding New Notes may be redeemed at Corp's option in whole, but not in part, at any time at a redemption price in cash equal to the greater of (i) 110 per cent. of their principal amount, and (ii) a make-whole amount equal to the sum of the present values of remaining scheduled payments of principal and interest, using a discount rate that is 50 basis points above the yield on US treasuries of similar maturity to the New Senior Notes and New Junior Notes, as applicable, plus, in each case, accrued and unpaid interest. The New Notes are subject to mandatory early redemption in certain circumstances. The New Notes must be redeemed prior to their stated maturity in whole or in part using the proceeds from the Mandatory Redemption Escrow Account, which is an escrow account to be established for redemption of the New Notes into which Corp will be required to deposit from time to time: 623

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- (a) releases to, or upon the order or instructions of, Corp or its subsidiaries of certain cash collateral or security for performance bonding (as described in more detail in Section 2, Part D.4); and (b) all net proceeds of asset sales received on or after 1 May 2003, other than up to L82 million of net proceeds from disposals of certain exempt specified assets and, if there are no New Junior Notes outstanding, proceeds reinvested in the non-US core business within specified time periods. Corp will apply amounts in the Mandatory Redemption Escrow Account to redeem first the New Junior Notes and then, under certain circumstances, the New Senior Notes, in each case at a redemption price in cash of 110 per cent. of their principal amount plus accrued and unpaid interest. In addition, in the event of either a Change of Control of Corp or the merger, consolidation or sale of all or substantially all the assets of Corp and its subsidiaries, taken as a whole, all of the New Notes must be redeemed in whole, but not in part, at a redemption price in cash equal to the greater of (i) 110 per cent. of their principal amount, and (ii) a make-whole amount equal to the sum of the present values of remaining scheduled payments of principal and interest, using a discount rate that is 50 basis points above the yield on US treasuries of similar maturity to the New Senior Notes and New Junior Notes, as applicable, plus, in each case, accrued and unpaid interest. CORP BELIEVES THAT INTEREST AND REDEMPTION (OPTIONAL AND MANDATORY) PAYMENTS WILL BE MET IN FULL AND ON TIME. CORP INTENDS TO REDEEM THE NEW NOTES AS QUICKLY AS POSSIBLE. THE VALUE OF THE NEW NOTES REFERRED TO ABOVE ARE SHOWN AT NOMINAL (FACE) VALUE FOR ILLUSTRATIVE PURPOSES AND SHOULD NOT BE TAKEN AS A GUIDE TO WHAT MARKET VALUES MAY BE ACHIEVED ONCE THE SCHEMES BECOMES EFFECTIVE. DETAILS OF THE RISKS RELATED TO OWNERSHIP OF THE NEW NOTES ARE SET OUT IN SECTION 2, PART F.4. NEW SHARES There is currently no public trading market for the New Shares. In addition, there can be no assurance as to the development or liquidity of any market for the New Shares. FURTHER DETAILS OF THE RISKS RELATING TO OWNERSHIP OF THE NEW NOTES ARE SET OUT IN SECTION 2, PART F.4. In light of the risks referred to above it is not possible for Corp or plc to assign a value to the New Shares referred to in Table 1 above. Scheme Creditors will therefore need to determine for themselves, based on the information set out in the Explanatory Statement and other publicly available information, the value to be ascribed to the New Shares. The following table is provided to assist Scheme Creditors to convert the value they ascribe to the New Shares into a recovery percentage based on the number of New Shares received for each L1,000,000 of Admitted Scheme Claim (refer to Table 1). Table 2 (which should not be construed as a valuation) is provided for illustrative purposes only.

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- 1.4 WHAT ARE THE ALTERNATIVES? If neither Scheme becomes effective, or both are terminated before the First Initial Distribution, the nature of the Group's financial position is such that Corp and plc would have no reasonable prospect of avoiding insolvency proceedings. If the Corp Scheme became effective but the plc Scheme did not become effective, then plc would inevitably have to enter some form of insolvency proceeding. If this occurred, Admitted Scheme Claims in the Corp Scheme would still receive their pro rata portion of the Restructuring Consideration. The UK insolvency proceeding alternatives to the Restructuring are as follows: (a) liquidation; or (b) administration. Of the two insolvency procedure alternatives, Corp and plc believe that a more advantageous realisation of Corp and plc's assets would be effected on an administration rather than on a liquidation. Accordingly, the insolvency analysis discussed in this Appendix does not specifically consider the possible returns that might be realised on a liquidation of either plc or Corp. An administrator is appointed by order of the Court, which must be satisfied by evidence that the statutory grounds for an appointment exist. The administrator will take charge of the company's affairs, business and property during the period for which the administration order is in force. The administrator displaces the company's board of directors from the management function and has the power to remove or appoint directors. The presentation of a petition for an administration order imposes an automatic moratorium on creditor action. Accordingly, except with the leave of the Court or the consent of the administrator, no steps may be taken to enforce security or repossess goods and no other proceedings may be commenced or continued against the company. In arriving at the conclusion that the Schemes are to be preferred to insolvency proceedings, and that administration would be more advantageous than liquidation, Corp and plc took into account the fact that certain causes of action are available to an administrator or a liquidator which are not available under a scheme of arrangement alone. In particular, a liquidator or administrator may be able to recover monies for the benefit of the company where it has given any voidable preference or been party to a transaction at an undervalue, and a liquidator (but not an administrator) may be able to do so where there has been wrongful or fraudulent trading in respect of which its past or present directors or others may be liable to contribute to its assets. Neither Corp nor plc is aware of any circumstances which might give rise to a claim of this nature. As between administration and liquidation, Corp and plc believe that the possibility of a claim existing which is not available to an administrator is outweighed by the more advantageous realisations expected from an administration. As between the Schemes and insolvency proceedings, Corp and plc believe that the possibility of such claims being available in insolvency proceedings is outweighed by the problems, uncertainties and delays which would be involved in an administration, which are discussed below. In relation to administration, there are two options available in relation to Corp (although in practice an administrator might choose to pursue some combination of the two): (a) a "trading administration" -- whereby the administrator would continue to fund the Group with a view to achieving a going concern sale of the businesses; or (b) a "liquidating administration" -- whereby the administrator would not fund the Group but instead would seek to sell Corp's assets on a break up or forced sale basis. As plc is not a trading company, the only insolvency option in relation to plc would be a "liquidating administration" or a liquidation. 625

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- 1.5 CAVEATS, LIMITATIONS AND UNCERTAINTIES OF THE INSOLVENCY ANALYSIS The insolvency analysis represents an illustrative estimate of insolvency values and recovery percentages based upon hypothetical insolvency proceedings as at 30 April 2003 whereby assets are converted into cash. The insolvency analysis is based on 31 December 2002 balance sheets, with the exception of cash in respect of Corp, where projected balances as at 30 April 2003 have been used. Certain deposits are denominated in foreign currencies and will be subject to foreign exchange fluctuations. In so far as insolvency might be an event that occurs in the future, the ultimate return to creditors will be determined by a series of complex circumstances relevant at the time of the insolvency. There may be unforeseen events, changes in economic conditions, and many other potential variations that could impact upon and change this analysis. PLC AND CORP HAVE PREPARED THE INSOLVENCY ANALYSIS ON THE BASIS OF CERTAIN ASSUMPTIONS WHICH THEY BELIEVE ARE REASONABLE IN THE CIRCUMSTANCES. HOWEVER, THE ASSUMPTIONS ARE SUBJECT TO SIGNIFICANT UNCERTAINTIES WHICH ARE BEYOND ANYONE'S CONTROL, AND UNANTICIPATED EVENTS AND CIRCUMSTANCES MIGHT MATERIALLY AFFECT THE ANTICIPATED RESULTS. Furthermore, given the complex international and multi-jurisdictional nature of the Group and the specialised nature of its businesses, together with the substantial interdependency of many of the Group's subsidiaries and the complex intercompany position (which is further explained in Section 1.6 below), estimating an illustrative insolvency recovery is an extremely difficult task. Any insolvency of a group as large as the Group will inevitably be a lengthy process and there is a serious risk (due to the international nature of a significant proportion of the Group and its assets) that Corp and plc would become subject to ancillary proceedings in other jurisdictions, which would increase the cost, uncertainty and delay associated with any such procedures and might reduce ultimate realisations. Unsecured creditors would not normally expect to receive their full entitlement until all assets had been realised, and all liabilities finally determined. Neither the assumptions nor the numbers generated in this comparison have been audited. While the insolvency values are presented with some specificity (albeit within a range), the actual results achieved would in all likelihood vary, and could vary in ways that may be material. Accordingly, there can be no assurance that the assumptions employed in determining the insolvency value of the assets will result in accurate estimations of such insolvency values. Similarly, the ability to channel proceeds through a large number of other entities, many of which are offshore and could be subject to their own individual insolvency proceedings and applicable laws, cannot be estimated with any high degree of certainty. The wide range of insolvency outcomes set out below reflect the following major uncertainties: (a) the telecommunications market continues to be significantly depressed, therefore there may be a shortage of suitable purchasers of Group companies, businesses or assets; (b) complex inter-company claims would only return a dividend to Corp and plc in an insolvency after significant delays and uncertainties relating to insolvency proceedings, many of which would take place outside the United Kingdom; (c) as a result of the complex structure of the Group, and the fact that the Group is run on business lines as opposed to entity lines, substantial difficulties may be perceived by prospective purchasers in satisfying their legal and due diligence requirements; (d) there is a serious risk of a significant decline in the operating companies' trading prospects in an insolvency scenario. In particular, there would potentially be a serious loss of value as a result of customer and supplier actions, as well as loss of key employees; (e) since March 2002 few credible, motivated and well financed purchasers of Group companies, businesses or assets have emerged; (f) lengthy litigation may be required to resolve certain claims before an insolvency practitioner would be prepared or able to declare a dividend in an insolvency; 626

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- (g) in the secured insolvency scenario, there is a possibility of a legal challenge in relation to the interim security; and (h) disputes as to the priority of major intercompany and external claims against Corp and plc will inevitably add to uncertainty and delay. As further explained in section 1.8, unless previously released certain creditors will have the benefit of interim security over cash in the Lockbox Accounts. Notwithstanding such security, plc and Corp believe that due to the complex nature of the Group and the likelihood of ancillary proceedings in other jurisdictions, THERE COULD BE A CONSIDERABLE DELAY BEFORE ANY DISTRIBUTION COULD BE MADE TO SECURED CREDITORS. Neither, Corp, plc, the Directors nor their advisers make any representation or warranty that the actual results would or would not approximate to the assumptions contained herein. Nothing in this Appendix constitutes a valuation. Where present values for different scenarios are shown they are provided for illustrative purposes only and are subject to the assumptions set out in this Appendix. 1.6 LIQUIDATING ADMINISTRATION ANALYSIS Under UK insolvency proceedings the liquidation of a company generally consists of the cessation of business, the identification and collection of assets and the sale of the company's assets by an insolvency practitioner, with subsequent distribution of the net proceeds to creditors in accordance with statutory priorities. Generally speaking, the position is the same in a so-called liquidating administration. Normally, in a liquidating administration sale values would be realised on a break up or forced sale basis. In a situation such as this it may be possible for an insolvency practitioner to achieve greater realisations based on the dependency of certain customers on the relevant company's products, and their willingness to pay, at least in the short term, to avoid disruption to their business. However, it is not possible to estimate the effect of this, and it may be the case that an administrator, as an officer of the Court, may be restricted in what he can or cannot do to realise the assets. In addition, the Group's primary point of leverage in this situation would be the know-how invested in its staff. In the event of an insolvency, key people within the Group may not be prepared to remain with the Group other than in the short term. The proceeds from any insolvency asset sales and recoveries would be first applied to satisfy the claims of secured creditors (assuming the interim security has not been released) and the costs and expenses of winding up the company (such as the fees for the insolvency practitioner, and of lawyers and other professionals including financial advisors and accountants retained by the insolvency practitioner, asset disposal expenses, litigation costs, and claims arising from the wind-down of operations of the companies' business). The liquidating administration analysis has been prepared assuming that Corp's and plc's assets, including the assets of their subsidiaries, are liquidated as at 30 April 2003. This analysis is based on the unaudited book values as at 31 December 2002 and projected cash balance as at 30 April 2003. Corp and plc are not aware of any events subsequent to 31 December 2002 which would materially alter the unaudited book numbers. The analysis represents an illustrative estimate of the hypothetical proceeds from the sale of assets based on the application of certain realisation percentages to the various categories of assets held by the Group's major subsidiaries. These are discussed further below. The assets of plc are primarily comprised of its entitlement to intercompany receivables and dividends from subsidiaries. The asset of Corp primarily comprise cash under its control and its entitlement to intercompany receivables and dividends from subsidiaries. 627

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- Factors considered in the liquidating administration analysis include the following: CASH AND EQUIVALENTS Cash and equivalents consists of cash in banks or operating accounts and liquid investments with maturities of three months or less and are assumed to be fully recoverable. Various cash balances which are secured or otherwise encumbered have not been included in the analysis. Some of these encumbered cash balances may be released over time, but the quantum cannot be known with certainty at this time. The balances in respect of Corp are based on projected book values of cash and cash equivalents as at 30 April 2003. Some of the deposits are denominated in foreign currencies and will be subject to foreign exchange fluctuations. INVESTMENTS This comprises the value of the Group's long term investments in certain listed and unlisted securities, discounted in certain cases to reflect possible lack of liquidity. ACCOUNTS RECEIVABLE Accounts receivable consists mostly of outstanding frame contract debt and accrued sales. The recovery of accounts receivable is based on management's estimate of collection, given such factors as that certain of the receivables are due from customers which are themselves in financial distress or undergoing liquidation, the ageing and historical collection patterns of the receivables, the status of work-in-process orders, advances received from customers, and the likelihood of set-off or counter claim in relation to interrupted contracts. In a liquidating administration, it is highly unlikely that accounts receivable will be fully collectable. Potential recoveries are very likely to be subject to substantial warranty/counter claims and therefore their timely receipt cannot be certain. For the purpose of this analysis, the recovery of accounts receivable from net external debtors has been assumed to fall within the range 10 per cent. to 30 per cent. of book value. INVENTORY Inventory comprises finished goods/goods shipped but not invoiced and work in progress ("WIP"). Many finished goods are specialist products and many are bespoke to individual contracts and would have little market value in a liquidating administration. Corp considers the sale value of stock held in WIP, for incomplete contracts, will not be substantial. This balance is also likely to comprise obsolete, or unsaleable stock or stock held as spares for current contracts. For the purposes of the insolvency analysis, Corp estimates the net amount recoverable from the sale of inventory is unlikely to exceed 5 per cent. of book value. PROPERTY, PLANT AND EQUIPMENT Property, plant, and equipment includes freehold and leasehold property, fixtures and fittings, leasehold improvements, computer equipment, motor vehicles, and network assets. The majority of the value in property, plant and equipment resides in the Marconi office premises in Germany, USA, Italy and the UK. For the purposes of the liquidating administration analysis, Corp estimates the overall net amount recoverable from tangible fixed assets (including taking account of the current market value of freehold property), will fall within the range 10 per cent. to 20 per cent. of net book value. INTANGIBLES Corp believes that the source codes of the Group's network software could have value to major customers and competitors in a going concern sale. However, significant negotiation would be required between the insolvency practitioner and the purchaser to settle warranty and/or counter-indemnity claims, business interruption claims, accounts receivable balances and related inventory 628

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- balances before any value would be realised. It is not possible to estimate accurately the time it would take to resolve these issues. In a liquidating administration there would be little time for negotiation. Accordingly, while Corp's and plc's trade names and other intangible assets may have some value, no liquidation value has been assumed in the liquidating administration analysis. In any case, Corp does not believe that any value ultimately realised from intangibles would materially affect the dividend received from a liquidating administration. DILUTION One of the primary disadvantages of insolvency is the serious uncertainty and delay which would arise in insolvency proceedings. This uncertainty and delay is difficult to analyse accurately in a group of the size and complexity of the Group, but would materially decrease any return to Scheme Creditors in an insolvency proceeding. On the basis that Corp and plc were to go into an insolvency procedure, it is assumed that absent financial support from the rest of the Group, the majority of the United Kingdom and foreign Subsidiaries would go into some form of local law insolvency procedure. There are substantial intercompany claims against Corp and plc. These intercompany claims would likely rank pari passu with unsecured trade and financial creditors of Corp and plc. Assuming pari passu distribution on an insolvency, a large percentage of any cash distribution made by an insolvency practitioner would have to be made to related Group companies, many of whom are non-United Kingdom based. Although Corp and plc believe that a proportion of cash held or controlled by Corp will find its way back to Corp and plc by means of intercompany balances and shareholdings, there is a significant risk in relation to these monies (for example legal challenges and priority of major intercompany and external claims, together with litigation at the Subsidiary level for breach of contract and other damages claims). Therefore, a risk factor of 50 per cent. to 70 per cent. has been applied to the cash balances to account for this, which would include the effect of the crystallisation of off balance-sheet liabilities. CREDITOR AND CONTINGENT CREDITOR CLAIMS Total actual and contingent creditor claims against Corp and plc comprise Scheme Creditors and Excluded Creditors (the most significant of which are inter-company creditors). Provision has also been made for additional claims specific to a liquidating administration, such as redundancy. In addition, there may be further claims as a result of warranties, breach of contract, business interruption and other factors. All of these would decrease realisations to creditors. For the purposes of the analysis, illustrative amounts of contingent claims of L100 million to L500 million in relation to Corp and L50 million to L100 million in relation to plc have been used to represent this further potential dilution risk. ESTIMATED OUTCOMES FROM A LIQUIDATING ADMINISTRATION Subject to the caveats and assumptions set out in this Appendix, CORP BELIEVES THAT THE RETURN TO CORP UNSECURED CREDITORS FROM A LIQUIDATING ADMINISTRATION WOULD BE IN THE RANGE OF 10 PER CENT. TO 12 PER CENT. This also assumes that the interim security has been released (see Section 1.8 below). SIMILARLY, THE RETURN TO PLC UNSECURED CREDITORS FROM A LIQUIDATING ADMINISTRATION WOULD BE APPROXIMATELY 2 PER CENT. IF THE INTERIM SECURITY HAS NOT BEEN RELEASED, THE ESTIMATED RETURN TO CORP UNSECURED CREDITORS WOULD BE APPROXIMATELY 2 PER CENT. AND THE RETURN TO PLC UNSECURED CREDITORS WILL LIKELY BE LESS THAN 1 PER CENT. 629

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- NONE OF THESE ESTIMATES APPLY DISCOUNTS FOR THE TIME VALUE OF MONEY. AS STATED IN SECTION 1.5, THERE IS LIKELY TO BE A SIGNIFICANT DELAY BEFORE ANY DISTRIBUTIONS ARE MADE. 1.7 TRADING ADMINISTRATION ANALYSIS Unlike a liquidating administration, the insolvency practitioner in a trading administration will try to maintain subsidiaries by drip feeding cash to keep them trading where it is cost effective to do this with a view to selling them as a going concern. There may be subsidiaries and businesses where it is not appropriate or cost-effective to provide funding and these will be dealt with in the same way as the liquidating administration scenario. In this scenario, many of the trading businesses and companies would be sold by foreign entities under the control of local insolvency procedures. In order to effect a successful trading administration substantial funding will be necessary. Corp and plc estimate this to be of the order of L200 million to L250 million. If the interim security has not been released, Corp does not believe that there will be sufficient free cash to fund a trading administration. Accordingly, the trading administration analysis necessarily assumes that the interim security has been released. The asset realisations in a trading administration are, where possible, derived from sales of shares in going concern entities. Given the generally depressed state of the telecommunications industry there is no certainty that the sale of shares will realise the values indicated, or indeed would be capable of achieving a going concern sale at all. The factors considered in the trading administration analysis include the following: ENTERPRISE VALUE AND BONDING CASH Consideration of the value of certain business lines has been undertaken and attempts have been made to allocate these to legal entities within the Group. Insolvency proceedings are likely to damage the goodwill and customer confidence in the business and hence the value of Corp's operating subsidiaries. Corp and plc have estimated the enterprise values for these business lines and have discounted the estimated enterprise values to reflect the discounted realisations under an insolvency scenario. It is assumed that bonding cash collateral may be freed to some extent in the case of a going concern sale. For the purposes of this analysis, it has been assumed that 10 per cent. to 40 per cent. of the bonding cash collateral will be released. DILUTION Significant dilution has been assumed for similar reasons to those stated in Section 1.6. The dilution amount differs between the trading administration and liquidating administration scenarios due to different realisation methods (sale of shares in a trading administration as opposed to sale of assets in a liquidating administration). A sale of shares has the additional benefit that a substantial amount of trade creditors and employee liabilities would pass to the purchaser, thereby reducing the effect of dilution. A reduced risk factor of 25 per cent. to 35 per cent. has therefore been applied to reflect the reliance on funds being remitted from other insolvency proceedings, particularly those outside the United Kingdom. DIFFICULTIES WITH A TRADING ADMINISTRATION Corp and plc believe that the following difficulties would be encountered in a trading administration: (a) few credible, motivated and well financed buyers have emerged since March 2002; (b) a trading administration may be difficult to manage in practice due to factors such as: (i) cross border insolvency procedures and differing jurisdictional frameworks; and 630

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- (ii) impacts of Chapter 11 in the US and potential "quarantining" restrictions imposed by the US Courts; (c) risk/reward of funding the trading administration through the sale process in return for a limited upside; (d) the substantial instability caused by insolvency procedures may cause significant damage to the Group's ability to hold onto customers and key employees. Certain customer contracts may also be terminated by virtue of insolvency; and (e) it is possible that a Government or group of large customers will intervene and force disposal of certain businesses to specific competitors, further depressing values. ESTIMATED OUTCOME FROM A TRADING ADMINISTRATION Subject to the caveats and assumptions set out in this Appendix, CORP BELIEVES THAT THE RETURN TO CORP UNSECURED CREDITORS FROM A TRADING ADMINISTRATION WOULD BE IN THE RANGE 11 PER CENT. TO 17 PER CENT. This assumes that the interim security has been released (see Section 1.8 below). Because plc is not a trading company, the only insolvency option in relation to plc would be a liquidating administration or a liquidation (see Section 1.6 above). THE ESTIMATED RANGES DOES NOT APPLY A DISCOUNT FOR TIME VALUE OF MONEY. AS MENTIONED IN SECTION 1.5, THERE ARE LIKELY TO BE SIGNIFICANT DELAYS BEFORE ANY DISTRIBUTIONS ARE MADE. 1.8 INTERIM SECURITY As part of the arrangements to effect the Restructuring, Corp agreed to provide interim security (over the cash held by Highrose Limited in the Lockbox Accounts) to the Group's principal lenders, being the Bank Creditors and the Secured Bondholders (other than plc's wholly owned subsidiary Ancrane) as well as to Barclays (as the only participating ESOP Derivative Bank which committed to support the Restructuring prior to 15 October 2002). Provision has been made for the interim security to be released prior to the Corp Scheme Meeting in circumstances tied to the prospects of the Corp Scheme being successfully implemented (as described more fully in Section 2, Part D.1). If for whatever reason the interim security has not been released prior to the Corp Scheme Meeting, neither Corp nor plc will proceed with their respective Schemes and the interim security will remain in place in any subsequent insolvency proceedings (meaning that the Bank Creditors, Bondholders and Barclays would rank ahead of all unsecured creditors of Corp with respect to the cash held in the Lockbox Accounts). The cash in the Lockbox Accounts is held in sterling, euro and US dollars accounts. The actual outcome from an enforcement of the interim security is therefore difficult to predict, and will fluctuate depending upon the time of enforcement and currency values. PLC AND CORP BELIEVE THAT DUE TO THE COMPLEX NATURE OF THE GROUP AND THE LIKELIHOOD OF ANCILLARY PROCEEDINGS IN OTHER JURISDICTIONS, THERE COULD BE A CONSIDERABLE DELAY BEFORE ANY DISTRIBUTION COULD BE MADE TO SECURED CREDITORS. Subject to the foregoing, CORP ESTIMATES THE RETURN TO SECURED CREDITORS WOULD BE 18 PER CENT. TO 20 PER CENT. (the range is narrow because the secured creditors principally benefit from the projected cash in the Lockbox Account) AND THE RETURN TO UNSECURED CREDITORS 2 PER CENT. OR LESS. DURING APRIL 2003, CORP MAY MAKE APPROVED CASH WITHDRAWALS FROM THE LOCKBOX ACCOUNTS. AN ENFORCEMENT OF THE INTERIM SECURITY AT THE BEGINNING OF APRIL 2003 WOULD THEREFORE LIKELY YIELD A HIGHER RETURN (APPROXIMATELY 1 PER CENT.) THAN AN ENFORCEMENT ON 30 APRIL 2003. THE RETURN TO PLC UNSECURED CREDITORS IS LIKELY TO BE LESS THAN 1 PER CENT. 631

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 6: INSOLVENCY ANALYSIS -------------------------------------------------------------------------------- 1.9 CONCLUSION For all the reasons stated above, Corp and plc believe that the Schemes are more beneficial to Scheme Creditors than an insolvency proceeding or enforcement of security. Corp and plc believe that the Schemes give greater certainty overall and the certainty of the day one distribution of cash, New Notes and New Shares is a major benefit to Scheme Creditors. This certainty would not be available under insolvency proceedings or enforcement of security. Furthermore, whilst the ultimate return to Scheme Creditors through an insolvency process is fraught with uncertainty, Corp and plc believe that in all likelihood Scheme Creditors (whether secured or unsecured) will get a better overall return from the Schemes, especially when the time value of money is taken into account. 632

(11) Where an Account Holder Letter is submitted to Bondholder Communications in which the confirmations set out in section 5, paragraphs (D), (E) and (F) of that Account Holder Letter are not made or a Claim Form is submitted to the Supervisors by a Scheme Creditor (other than the Eurobond Trustee or BoNY) whose Scheme Claim is subsequently Admitted in which the confirmations set out in paragraphs (3) and (4) of Box 3 of that Claim Form are not made, Bondholder Communications or, as the case may be, the Supervisors shall inform the Distribution Agent accordingly and Corp may direct that (i) if the New Creditor Shares or New Notes or any of them are listed on a securities exchange, the Distribution Agent shall, on behalf of the Escrow Trustee, sell or procure the sale of the New Notes and the New Creditor Shares which would otherwise have been Distributed and shall instead pay the cash proceeds of such sale to the relevant Eligible Recipient (after deducting all applicable expenses including foreign currency 645

Any sale made pursuant to sub-paragraph (i) of this sub-clause (11) shall be made for the best terms reasonably available at the time of the sale. (12) Where an Account Holder Letter or Claim Form is submitted in which the confirmations set out in section 5, paragraphs (D), (E) and (F) of that Account Holder Letter or paragraphs (3) and (4) of Box 3 of that Claim Form are made but, on the face of the Account Holder Letter or Claim Form, as the case may be, it is apparent that the confirmations may be inaccurate or Corp has reason to believe that a Distribution made in accordance with the Account Holder Letter or Claim Form, as the case may be, might be in breach of any of the securities laws described in part 1, Section 2 of Parts D.16 and D.17 of the Scheme Document: (a) in the case of the Account Holder Letter, Bondholder Communications shall draw that Account Holder Letter to the attention of Corp and the Supervisors; and (b) in the case of the Claim Form, the Supervisors shall draw that Claim Form to the attention of Corp; and Corp may, after such investigation as it may deem appropriate in the circumstances, direct the Distribution Agent (acting on behalf of the Escrow Trustee) (i) if the New Creditor Shares or New Notes or any of them are listed on a securities exchange, to sell or procure the sale of the New Notes and the New Creditor Shares which would otherwise have been Distributed and instead and pay the cash proceeds of such sale to the relevant Eligible Recipient (after deducting all applicable expenses including foreign currency conversion costs incurred) to the cash account set out in the relevant Account Holder Letter or Claim Form; or (ii) if the New Creditor Shares or New Notes or any of them are not listed on a securities exchange, to pay a sum of cash in sterling which is substantially equivalent in value to such New Creditor Shares or New Notes and determined in accordance with clause 30(7)(e)(ii) of the Corp Scheme to the cash account set out in the relevant Account Holder Letter or Claim Form. Any sale made pursuant to sub-paragraph (i) of this sub-clause (12) shall be made for the best terms reasonably available at the time of the sale. (13) In relation to each Distribution made by it, in any case where it would otherwise be required to distribute a fraction of a New Note or a fraction of a New Creditor Share to an Eligible Recipient, the Distribution Agent (acting on behalf of the Escrow Trustee) shall, in accordance with sub-clause 30(6) of the Corp Scheme, (a) if the New Creditor Shares or New Notes or any of them are Listed, aggregate all such fractions and sell the relevant number of New Notes and New Creditor Shares in the market and pay the net proceeds of such sale (after deducting all costs of the sale and paying all fractional entitlements) to the Escrow Account specified for this purpose in a Transfer Notice and (b) if the New Creditor Shares or New Notes are not Listed, round down to zero all fractional entitlements of Eligible Recipients to such unlisted New Creditor Shares and New Notes and transfer (if required) to the Escrow Account specified for this purpose in a Transfer Notice all fractional entitlements to those New Shares and New Notes (as the case may be) which, but for this sub-paragraph (b), Eligible Recipients would have received. No fraction of a unit of currency shall be Distributed by the Distribution Agent and any cash remaining after the relevant Distribution as a result of any such fractional entitlements shall be paid by the Distribution Agent to Corp. In this paragraph, the "RELEVANT NUMBER OF NEW NOTES OR NEW CREDITOR SHARES" means the number of New Notes and New Creditor Shares that would have resulted from the aggregation of all fractional entitlements and the rounding down of the result to the nearest whole New Note and New Creditor Share, respectively. (14) In each case where Undistributed Scheme Consideration is to be applied in reimbursing Corp for any SDRT Expense it has incurred in excess of L500,000 in accordance with clause 25(2) of the Corp Scheme, 646

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- the Supervisors shall give the Distribution Agent the directions necessary to make that reimbursement including, but not limited to, the following: (a) the amount of the SDRT Expense that is to be reimbursed; (b) if any Element of Undistributed Scheme Consideration other than cash is required, the number of New Creditor Shares and/or New Notes to be sold; and (c) Corp's bank account details to which the reimbursement should be made. 8.

This clause 8 applies only to Distributions made under the plc Scheme. (2) As set out in the plc Scheme, the Supervisors shall determine the Scheme Claims and shall decide whether or not they shall be Admitted. (3) In respect of each Distribution, the Supervisors will deliver to the Escrow Trustee (with a copy to the Distribution Agent) a duly completed Distribution Notice (in the form agreed between the Supervisors, the Escrow Trustee and the Distribution Agent) identifying each Admitted Scheme Creditor (which expression, in this sub-clause (3), includes the Eurobond Trustee and BoNY but does not include Account Holders or Designated Recipients who are dealt with as provided in sub-clause (6) below) to which the Distribution is to be made, the amount of each Element of Scheme Consideration (and the relevant Trust Funds and Escrow Accounts from which it should be taken) to be received by that Admitted Scheme Creditor, the cash or securities accounts of that Admitted Scheme Creditor to which the relevant portion of the Scheme Consideration is to be credited and, if applicable, whether that Admitted Scheme Creditor has elected to receive ADRs instead of New Creditor Shares. In respect of each Distribution Notice that contains a reference to BoNY or the Eurobond Trustee, the words "to be distributed to Designated Recipients in accordance with the directions contained in clauses 7 and 8 of the Escrow and Distribution Agreement dated 27 March 2003 given by such Scheme Creditor" shall be inserted in parentheses following each such reference. (4) Except in the case of the First Initial Distribution, the Distribution Agent will make the relevant Distribution on behalf of the Escrow Trustee within 5 Business Days after having received a duly completed Distribution Notice from the Supervisors. Subject as provided in sub-clause (6)(f), the Distribution Agent will make the First Initial Distribution on the Effective Date.

(6) Subject to the Scheme Claims of the Eurobond Trustee and BoNY being the subject of a Distribution Notice, each of the Eurobond Trustee or BoNY, as the case may be, with the authority hereby given and approval of the Supervisors, the Escrow Trustee and Ancrane, hereby directs the Distribution Agent, acting on behalf of the Escrow Trustee, to: (a) in the case of the Eurobond Trustee, pay, at the same time as the relevant Distribution is made, the cash Element of each Distribution which would otherwise have been made to it to (i) all Account Holders (other than Morgan Stanley to the extent that Morgan Stanley is the Account Holder for Ancrane) which had Eurobonds credited to their accounts on the Effective Date by a pro rata distribution through Euroclear and Clearstream, Luxembourg or (ii) if (for any reason), such a pro rata distribution through Euroclear and Clearstream, Luxembourg is not possible, in the manner contemplated in paragraph (b) below; (b) in the case of BoNY (or the Eurobond Trustee pursuant to sub-clause (6)(a)(ii) above), subject as provided in paragraph (f) below, pay to each Designated Recipient, at the Specified Time (as defined below), such Designated Recipient's proportion of the cash Element (together with any entitlement to interest thereon) which would otherwise have been made to BoNY in respect of the Yankee Bonds or the Eurobond Trustee in respect of the Eurobonds, as the case may be, in accordance with the cash payment directions contained in the relevant Account Holder Letter; and (c) subject to sub-clauses (8) and (9) and subject as provided in paragraph (f) below, distribute to each Designated Recipient, at the Specified Time, such Designated Recipient's proportion of the New Notes Element and the New Creditor Shares Element of the relevant Distribution (and any entitlement to interest and dividends) which would otherwise have been distributed to the relevant Trustee in accordance with the security delivery directions (including, for the avoidance of doubt, directions as to the currency of the Senior Notes to be delivered and in relation to any ADRs to be delivered in lieu of New Creditor Shares) contained in the relevant Account Holder Letters; (d) other than any payments of cash made in accordance with sub-paragraph (a)(i) above, if the Relevant Conditions (as defined below) have not been satisfied in relation to a Designated Recipient of Scheme Consideration initially attributable to the Eurobond Trustee or BoNY, as the case may be, (whether in the Initial Distribution or any Further Distribution) on or before the termination of the Scheme, to (i) (in the case of the Eurobond Trustee) hold that Scheme Consideration to the order of the Eurobond Trustee pending any directions from it, which directions will be given by the Eurobond Trustee if and to the extent that it is authorised or directed by an extraordinary resolution passed at a Eurobond Meeting or by court order and (ii) (in the case of BoNY) transfer all such 648

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- Scheme Consideration to BoNY or to its order (including, but without limitation, by way of a payment into court); (e) in this sub-clause (6), "RELEVANT CONDITIONS" in relation to a Designated Recipient means that (i) a duly completed Account Holder Letter naming that Designated Recipient; and (ii) confirmation satisfactory to Bondholder Communications that corresponding Custody Instructions have been given have been received by Bondholder Communications and confirmed by it to the Distribution Agent and all information necessary to make the relevant Distribution has been provided by Bondholder Communications to the Distribution Agent and "SPECIFIED TIME" means the same time as the relevant Distribution is made where the Relevant Conditions have been satisfied in relation to a Designated Recipient or, where this is not the case, as soon as practicable after the Relevant Conditions have been satisfied in relation to that Designated Recipient. For the avoidance of doubt, once the Relevant Conditions are met in respect of a Designated Recipient, the Distribution Agent will pay or transfer to that Designated Recipient all Scheme Consideration (and any income accrued in respect of it) to which that Designated Recipient would have been entitled had the Relevant Conditions in relation to it been met prior to 17th April, 2003 without further direction from any of the parties to this Agreement; and (f) in recognition of the fact that the Distribution Agent is limited in its ability to prepare and process payment and transfer instructions ("INSTRUCTIONS"), the Distribution Agent shall act in the following manner in preparing and giving effect to the First Initial Distribution: (i) prepare preliminary Instructions as soon as practicable after it has received the necessary information from the Supervisors in accordance with sub-clause (3) above or Bondholder Communications in accordance with sub-clause (5)(g) above and complete such Instructions in the Order of Priority (as defined below) as swiftly as possible following the determination of both the Scheme Rate and the Effective Date; (ii) on the Effective Date process as many Instructions which have been completed as it is able to do in the Order of Priority; and (iii) on each Business Day after the Effective Date until completion of the First Initial Distribution, process as many Instructions which have been completed as it is able to in the Order of Priority. For the purpose of this sub-clause (f), "ORDER OF PRIORITY" means, first, to each of the Scheme Creditors named in the First Initial Distribution Notice (which, for the avoidance of doubt, shall include the Trustees but not Designated Recipients) and, secondly, to each Designated Recipient by reference to the principal amount of Bonds represented by the Account Holder Letter in which it is named as the Designated Recipient starting with the Designated Recipient which has the highest principal amount so represented. It is currently envisaged that the Distribution Agent will be able to complete a maximum of 1,000 Instructions per Business Day and to process a maximum of 5,000 Instructions per Business Day. (7) In respect of each Distribution Notice that directs the Escrow Trustee and the Distribution Agent to distribute ADRs instead of New Creditor Shares in accordance with sub-clause (3) above and any elections in Account Holder Letters to receive ADRs instead of New Creditor Shares communicated to the Distribution Agent in accordance with sub-clause (5) above, the Escrow Trustee shall procure that the Distribution Agent, acting on behalf of the Escrow Trustee, shall: (a) subject to paragraph (c) below, transfer the New Creditor Shares relating to the relevant Eligible Recipient to the ADR Depositary; (b) arrange for the distribution of ADRs relating to those New Creditor Shares to entitled Eligible Recipients; and (c) where there are any New Creditor Shares which are not sufficient in number to equate to one ADR and which therefore cannot be transferred to the ADR Depositary in accordance with paragraph (a) 649

(10) In respect of each Distribution Notice that directs the Escrow Trustee and the Distribution Agent to distribute New Creditor Shares, the Escrow Trustee shall procure that the Distribution Agent transfers on its behalf the requisite number of New Creditor Shares to the Registrars and instruct the Registrars to transfer the same to the relevant Scheme Creditor or Designated Recipient in accordance with the relevant Distribution Notice and sub-clause (6) above. For this purpose the Escrow Trustee shall give the Registrars standing instructions in the Letter of Instruction to effect the transfers contemplated by this sub-clause (10) and hereby irrevocably agrees not to withdraw or alter such instructions without the prior approval of the Supervisors. (11) In relation to each Distribution made by it, in any case where it would otherwise be required to distribute a fraction of a New Note or a fraction of a New Creditor Share to an Eligible Recipient, the Distribution 650

No fraction of a unit of currency shall be Distributed by the Distribution Agent and any cash remaining after the relevant Distribution as a result of any such fractional entitlements shall be paid by the Distribution Agent to plc. In this paragraph, the "RELEVANT NUMBER OF NEW NOTES OR NEW SHARES" means the number of New Notes and New Creditor Shares that would have resulted from the aggregation of all fractional entitlements and the rounding down of the result to the nearest whole New Note and New Creditor Share, respectively. 9. RIGHTS, POWERS AND DUTIES OF THE ESCROW TRUSTEE AND THE DISTRIBUTION AGENT (1) Neither the Escrow Trustee nor the Distribution Agent will exercise any voting rights attaching to the New Notes or the New Shares whilst they are held in any of the Trust Funds. (2) The duties, responsibilities and obligations of the Escrow Trustee and the Distribution Agent shall be limited to those expressly set forth herein and no duties, responsibilities or obligations shall be inferred or implied. Neither the Escrow Trustee nor the Distribution Agent shall be required to, and nor shall either of them, expend or risk any of its own funds or otherwise incur any financial liability in the performance of any of its duties under this Agreement save where the same arises as a result of its negligence, misfeasance, breach of duty or wilful default. (3) Each of the Escrow Trustee and the Distribution Agent shall not be responsible for, or charged with knowledge of, the terms and conditions of any other agreement, instrument or document executed between the other parties and to which it is not a party, other than the Schemes and except such agreements, instruments or documents as may be specifically referred to in this Agreement. (4) Corp agrees (subject as provided in sub-clause (5)) to reimburse each of the Escrow Trustee and the Distribution Agent on demand for, and to indemnify (on an after tax basis) and hold each of the Escrow Trustee and the Distribution Agent harmless against and with respect to, any and all loss, liability, damage or expense (including, but without limitation, reasonable legal fees, costs and disbursements) that the Escrow Trustee or, as the case may be, the Distribution Agent may suffer or incur in connection with it acting in accordance with the Corp Scheme, the plc Scheme or this Agreement, except to the extent that such loss, liability, damage or expense arises from its own negligence, misfeasance, breach of duty or wilful default. (5) In case any action shall be brought against either the Escrow Trustee or the Distribution Agent (the "INDEMNIFIED PERSON") in respect of which recovery may be sought from Corp (the "INDEMNIFIER"), under sub-clause (4), the indemnified person shall promptly notify the indemnifier in writing but (subject as provided below) failure to do so will not relieve the indemnifier from any liability under this Agreement. Subject to sub-clause (6), the indemnifier may participate at its own expense in the defence of any action. (6) If it so elects within a reasonable time after receipt of the notice referred to in sub-clause (5), the indemnifier may assume the defence of the action with legal advisers chosen by it and approved by the indemnified person. Notwithstanding such election the indemnified person may employ separate legal advisers, and the indemnifier shall bear the fees and expenses of such separate legal advisers if: (a) the use of the legal advisers chosen by the indemnifier to represent the indemnified person would present such legal advisers with a conflict of interest; 651

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- (b) the actual or potential defendants in, or targets of, any such action include both the indemnified person and the indemnifier and the indemnified person concludes that there may be legal defences available to it which are different from or additional to those available to the indemnifier; (c) the indemnifier has not employed legal advisers satisfactory to the indemnified person (acting reasonably) to represent the indemnified person within a reasonable time after notice of the institution of such action; or (d) the indemnifier authorises the indemnified person to employ separate legal advisers at the expense of the indemnifier. If the indemnifier assumes the defence of the action, the indemnifier shall not be liable for any fees and expenses of legal advisers of the indemnified person incurred thereafter in connection with the action, except as stated above. (7) Corp shall not be liable in respect of any settlement of any action effected without its consent, such consent not to be unreasonably withheld or delayed. Corp shall not, without the prior written consent of the indemnified person, where the indemnified person is an actual or is reasonably likely to be a potential party to such claim or action, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim or action in respect of which recovery may be sought hereunder unless such settlement, compromise or consent includes an unconditional release of the indemnified person from all liability arising out of such claim or action and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of the indemnified person. (8) Subject as provided in sub-clause (9), Corp agrees to reimburse each Designated Recipient on demand for, and to indemnify and hold each of them harmless against and with respect to, any Loss to the extent that such Loss arises out of any negligence, fraud, breach of duty, wilful misconduct or misfeasance of Bondholder Communications. For this purpose "LOSS" means any loss suffered by a Designated Recipient: (a) in the case of the First Initial Distribution under each Scheme, through it failing to receive any part of its part of that First Initial Distribution or it receiving any part of its part of that First Initial Distribution after the Effective Date of the relevant Scheme; and (b) in the case of the Initial Distribution (other than the First Initial Distribution) under each Scheme, through it failing to receive any part of its part of that Initial Distribution, in each case except where the failure to receive any part of the Distribution is as a result of the operation of any of clause 7(11), 7(12), 7(13), 8(8), 8(9) and 8(11) of this Agreement. (9) The right of reimbursement and indemnity set out in sub-clause (8) will not apply: (a) in the case of the First Initial Distribution under either Scheme, where an Account Holder Letter was submitted after 5.00 p.m. (New York City time) on 17th April 2003, or was submitted before that time and date but was incomplete or contained any error or inconsistency which had not been rectified by that time and date to Bondholder Communications' satisfaction (acting as a reasonably prudent expert); or (b) to the extent that the loss arose as a result of any action taken or omitted by the relevant Designated Recipient or its connected Bondholder, Account Holder or Intermediary or any clearing system or agent of a clearing system or any other party to this Agreement (other than Corp or plc); or (c) where all necessary information in respect of a Designated Recipient has been given by Bondholder Communications to the Distribution Agent by the date specified in, and as required by, but subject as provided in, clause 7(5)(g) or 8(5)(g), as the case may be, Scheme Consideration under either Scheme is not received by that Designated Recipient or, in the case of the First Initial Distribution, is not received by him on the Effective Date of the relevant Scheme.

(14) Neither the Escrow Trustee nor the Distribution Agent shall be required to take any legal action or proceedings unless it has been indemnified and/or provided with security to its satisfaction against all actions, proceedings, claims and demands to which it may render itself liable and all costs, charges, damages, expenses and liabilities which it may incur by so doing.

Neither the Escrow Trustee nor the Distribution Agent shall be liable for acting properly and in accordance with this Agreement on any opinion, advice or information which is so conveyed, even if the opinion, advice or information contains some error of which the Escrow Trustee or, as the case may be, the Distribution Agent is not aware or which is not manifest. (18) Each of the Escrow Trustee and the Distribution Agent may retain for its own benefit, without liability to account to any other person, any fee or other sum received by it for its own account. (19) The Distribution Agent may provide advisory or other services to or engage in any kind of business with any person party to, or affected by, the arrangements the subject of this Agreement and may do so without any obligation to account to or disclose any such arrangements to any person but not in respect of the Schemes unless permitted by a Scheme or this Agreement. (20) Each of the Escrow Trustee and the Distribution Agent may exercise any of its rights and perform any of its duties, obligations and responsibilities under this Agreement through its paid or unpaid agents, which may be corporations, partnerships or individuals (whether or not lawyers or other professional persons) and, provided that it has exercised reasonable care in the selection of any such agent, shall not be responsible for any misconduct or omission on the part of, or be bound to supervise the proceedings or acts of, any such agent save where the same arises as a result of the negligence, misfeasance, breach of duty or wilful default on the part of the agent. Any such agent which is engaged in any profession or business shall be entitled to charge and be paid all usual fees, expenses and other charges for its services. (21) Each of the Escrow Trustee and the Distribution Agent may refrain from doing anything which would or might in its opinion be contrary to any law or any directive or regulation of or having the force of law to which it is subject or which would or might otherwise render it liable to any person and may do anything which is, in its reasonable opinion, necessary to comply with such law, directive or regulation. (22) If so instructed by the Supervisors, each of the Escrow Trustee and the Distribution Agent shall concur with the other parties to this Agreement in the making of any modification to this Agreement which is certified by the Supervisors in writing as (a) relating to administrative matters or being a technical amendment arising out of a manifest or proven error and (b) not in the Supervisor's reasonable opinion materially prejudicial the Scheme Creditors or Designated Recipients affected by such modification. 10. COVENANTS OF THE ESCROW TRUSTEE The Escrow Trustee shall not: (1) create or permit to subsist any mortgage, standard security, pledge, lien, charge or other Security Interest whatsoever (unless arising by operation of law), upon the whole or any part of its assets or its undertakings, present or future; (2) sell, assign, transfer, convey, lease or otherwise dispose of, or deal with, or grant any option or present or future right to acquire all or any of its properties, assets, or undertakings or any interest, estate, right, title or benefit therein or thereto or agree or attempt to purport to do any of the foregoing except, in all cases, to the extent necessary to perform its obligations under this Agreement; (3) save in respect of the trusts created by this Agreement, permit any person other than itself to have any equitable interest in any of its assets or undertakings or any interest, estate, right, title or benefit therein; (4) have an interest in any bank account, other than the bank accounts comprised in the Escrow Accounts and the Corporate Expenses Account or to withdraw any sum from the Corporate Expenses Account other than a Permitted Withdrawal; (5) carry on any business other than as Escrow Trustee for the Schemes and the related activities described in the Schemes or as contemplated in this Agreement; 654

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- (6) incur any indebtedness whatsoever or give any guarantee or indemnity in respect of any indebtedness or obligation of any person; (7) consolidate or merge with any other person or convey or transfer substantially all of its properties or assets to any other person; (8) have any employees or premises or subsidiaries; and (9) pay any dividend or make any other distribution to its shareholders or issue any further shares or alter any rights attaching to its shares as at the date of this Agreement. 11. INVESTMENTS (1) The Escrow Trustee hereby directs the Distribution Agent to credit all interest earned (including any interest in the form of debt securities) and dividends (or any other rights or benefits) or other cash or property received in respect of any assets in any Escrow Account to the relevant account forming part of that Escrow Account until payment or transfer to Admitted Scheme Creditors in accordance with the provisions of this Agreement. The Supervisors shall have the power to direct (but shall not be obliged to direct) that any such property that cannot be conveniently held by the Escrow Trustee shall be sold and the cash proceeds of such sale dealt with in accordance with this clause. (2) Any payment of interest earned (including any interest in the form of debt securities) or dividends received in respect of any assets in any Escrow Account ("PROFITS") to Eligible Recipients shall only be made by the Distribution Agent (acting on behalf of the Escrow Trustee) if the Supervisors have so instructed the Distribution Agent, having first instructed the Distribution Agent (as agent for the Escrow Trustee) to retain a reserve in respect of any and all taxes payable by the Escrow Trustee, or required to be deducted by the Escrow Trustee (whether by law or by agreement with the Inland Revenue), in respect of such Profits being distributed. 12. CONDUCT OF TAXATION MATTERS (1) For the purposes of this clause 12, a "BARE TRUST" is a trust which is not a settlement for the purposes of section 43 Inheritance Tax Act 1984, whereby the trust property is held by the Escrow Trustee for another person absolutely entitled as against the Escrow Trustee within the meaning of section 60(2) Taxation of Chargeable Gains Act 1992 and which is a bare trust for all income tax purposes. (2) As soon as reasonably practicable after the Effective Date, the Escrow Trustee shall seek confirmation from the Inland Revenue that the arrangements constituted by the Corp Scheme, the plc Scheme and this Agreement result in the Trust Funds being held on bare trust (such confirmation being a "FAVOURABLE CONFIRMATION"). The Escrow Trustee shall notify Corp and the Supervisors within 21 days of a receipt of a Favourable Confirmation. (3) If the Inland Revenue at any time confirms to the Escrow Trustee that the Trust Funds are not held on bare trust or commences an enquiry into any tax return submitted on the basis that the Trust Funds are held on bare trust (an "ADVERSE CONFIRMATION"), the provisions of sub-clauses (6) and (8) shall apply. If the Inland Revenue declines to give a Favourable Confirmation, or has not given a Favourable Confirmation within 3 months of the date on which confirmation was sought under sub-clause (2) above, but does not give an Adverse Confirmation (a "NON-CONFIRMATION"), the provisions of sub-clauses (7) and (8) shall apply. (4) Unless and until the Escrow Trustee receives or becomes aware of an Adverse Confirmation or Non-Confirmation, it shall direct the Distribution Agent to make distributions to Eligible Recipients without retaining or deducting any amounts on account of tax, save as provided in sub-clause 11(2). For the avoidance of doubt, nothing in this clause 12 affects the obligations of the Distribution Agent in clause 11(2). 655

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- (5) Corp agrees that, if and when it recovers any input value added tax incurred by it in relation to the issue of New Shares or New Notes under the Corp Scheme, it shall establish the Escrow Tax Fund as a separate fund to be applied only in accordance with the following provisions. (a) Subject to paragraph (b) below, the Escrow Tax Fund shall only be used: (i) to make any repayment of the input value added tax comprising the Escrow Tax Fund for which Corp is determined or agreed to be liable to HM Customs & Excise (together with any applicable interest or penalties) (a "VAT REPAYMENT"); (ii) to meet any Tax Liability (as defined in sub-clause (8)(d) below) of the Escrow Trustee; or (iii) to pay any Costs as provided in sub-clause (9). (b) The Escrow Tax Fund shall be used to meet a VAT Repayment in priority to a Tax Liability or any Costs (as defined in sub-clause (9)). If any or all of the Escrow Tax Fund has been used to meet a Tax Liability or any Costs (as defined in sub-clause (9)) and is later required to meet a VAT Repayment, such that there are insufficient sums in the Escrow Tax Fund to meet Corp's liability to make the VAT Repayment, the Supervisors hereby direct the Escrow Trustee (which hereby directs the Distribution Agent) to pay to Corp an amount equal to the deficiency from the Reserve Corp Scheme Creditors Fund or the Combined Corp Funds, or the Reserve plc Scheme Creditors Fund or the Combined plc Funds, as the case may be. (c) Corp may cease to hold the Escrow Tax Fund as a separate fund, and its use shall cease to be subject to the restrictions referred to in paragraph (a) above on the occurrence of any of the following: (i) the Escrow Trustee's receipt of a Favourable Confirmation (including a Favourable Confirmation as set out in sub-clause (7)(c)); (ii) the determination by a court of competent jurisdiction from which neither party appeals that the Scheme Consideration is held on bare trust; or (iii) after the closure of all the Escrow Accounts as set out in clause 13, the confirmation by the Escrow Trustee that it has no further Tax Liability (as defined in sub-clause (8)(d)) in connection with its activities as escrow trustee under the Schemes. (d) For the avoidance of doubt, nothing in this sub-clause (5) shall require Corp to conduct its tax affairs in a particular manner, to disclose any information relating to its tax affairs, or to contest any assessment to value added tax made by HM Customs & Excise. (6) This sub-clause applies if the Escrow Trustee receives an Adverse Confirmation. (a) The Escrow Trustee shall, within 21 days of receiving the Adverse Confirmation, inform the Supervisors. Unless and until the Escrow Trustee receives a subsequent Favourable Confirmation, it shall retain a reserve for any tax liability it may have on the basis that the Trust Funds are not held on bare trust, in accordance with sub-clause (8). (b) The Escrow Trustee shall take reasonable steps to pursue correspondence with the Inland Revenue to obtain a Favourable Confirmation. (c) If, after taking the steps referred to in paragraph (b) above, the Escrow Trustee is unable to obtain a Favourable Confirmation, the Escrow Trustee shall take reasonable steps to pursue any available appeal. The Escrow Trustee shall not be required to take any steps where, in the opinion of the Supervisors, the cost of undertaking those steps outweighs any likely benefit or where leading tax counsel has advised either that an appeal is not likely to succeed or that it would not be reasonable to pursue an appeal in the light of any settlement offered. (d) Until (i) the Adverse Confirmation is upheld by a court of competent jurisdiction from whose decision the Escrow Trustee does not appeal, (ii) the Escrow Trustee is not required to take any further steps in respect of the Adverse Confirmation in accordance with paragraph (c) above, or 656

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- (iii) leading tax counsel advises the Escrow Trustee otherwise, and in so far as it is able to do so without incurring any penalty, the Escrow Trustee shall file any tax returns on the basis that the Trust Funds are held on bare trust. This paragraph is without prejudice to sub-clause (8) below. (7) This sub-clause applies if the Escrow Trustee receives or becomes aware of a Non-Confirmation. (a) The Escrow Trustee shall, within 21 days of receiving or becoming aware of the Non-Confirmation, inform the Supervisors. Unless and until the Escrow Trustee receives a subsequent Favourable Confirmation, it shall retain a reserve for any tax liability it may have on the basis that the Trust Funds are not held on bare trust, in accordance with sub-clause (8). (b) The Escrow Trustee shall file any tax returns on the basis that the Trust Funds are held on bare trust, unless leading tax counsel advises the Escrow Trustee to file on a different basis. This paragraph is without prejudice to sub-clause (8) below. (c) The agreement by the Inland Revenue of any tax return filed by the Escrow Trustee on the basis that the Trust Funds are held on bare trust shall be taken as a Favourable Confirmation. Where the Escrow Trustee has filed such a tax return and no notice of enquiry has been issued pursuant to Schedule 18 Finance Act 1998 within the prescribed time period, there shall be deemed to have been a Favourable Confirmation unless leading tax counsel advises otherwise. (d) If at any point the Escrow Trustee receives an Adverse Confirmation, the provisions of sub-clause (6) will apply. (8) If the Escrow Trustee receives an Adverse Confirmation or Non-Confirmation, the Supervisors hereby direct the Escrow Trustee (which hereby directs the Distribution Agent) to pay or set aside amounts (taking into account any amounts already paid or set aside under sub-clause 11(2) and the balance of the Escrow Tax Fund) on account of any tax payable by the Escrow Trustee (on the assumption that the Trust Funds are not held on bare trust) in respect of (i) assets or income comprising distributions to Scheme Creditors which have already been made ("PAST TAX LIABILITY"), and (ii) distributions of assets or income comprising distributions to Scheme Creditors which have not yet been made ("FUTURE TAX LIABILITY") in the following manner: (a) If the Supervisors have not terminated the Waiting Period in accordance with clause 24 of the Corp Scheme, or clause 24 of the plc Scheme as the case may be, the Distribution Agent shall set aside amounts from the Reserve Corp Scheme Creditors Fund or the combined Unadmitted Known Corp Scheme Creditors Fund and Reserve Corp Scheme Creditors Fund (the "COMBINED CORP FUNDS") or from the Reserve plc Scheme Creditors Fund or the combined Unadmitted Known plc Scheme Creditors Fund and Reserve plc Scheme Creditors Fund (the "COMBINED PLC FUNDS"), as the case may be: (i) in the case of amounts in respect of the Past Tax Liability, forthwith after the receipt by the Escrow Trustee of the Adverse Confirmation or Non-Confirmation; and (ii) in the case of amounts in respect of a Future Tax Liability, at the time at which the distribution to which that liability relates is made. If, however, at that time the Supervisors have terminated the Waiting Period as set out above, amounts in respect of a Future Tax Liability shall be retained as provided for in paragraph (b)(ii) below. (b) If the Supervisors have terminated the Waiting Period as set out in paragraph (a) above or decide to do so as a result of the operation of this sub-clause (8), (i) amounts shall be set aside in respect of the Past Tax Liability from the Combined Corp Funds or the Combined plc Funds, as the case may be, forthwith after the receipt by the Escrow Trustee of the Adverse Confirmation or Non-Confirmation; and (ii) amounts in respect of any Future Tax Liability shall be retained by the Distribution Agent out of the distribution to which that liability relates. 657

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- (c) The quantum of any amounts set aside or retained pursuant to this sub-clause (8) shall be directed by the Supervisors. (d) Any amounts which are determined or agreed to be payable on account of any tax liability of the Escrow Trustee (a "TAX LIABILITY") shall be met out of the following amounts and in the following priority: (i) in the first instance, out of amounts already paid or set aside under sub-clause 11(2); (ii) secondly, out of the Escrow Tax Fund; and (iii) thirdly, out of any amounts set aside in accordance with this sub-clause (8), Corp hereby agrees to make any payments necessary pursuant to the operation of this paragraph from the Escrow Tax Fund to the Escrow Trustee. The Supervisors hereby direct the Escrow Trustee (which hereby directs the Distribution Agent) to pay any amounts to be paid in accordance with paragraphs (i) and (iii) above in satisfaction of its Tax Liability. (e) To the extent that any amounts set aside pursuant to this sub-clause (8) are not, in the event, required to meet a Tax Liability, or, in the case of any amounts paid in satisfaction of a Tax Liability, are subsequently repaid by the Inland Revenue, then such amounts shall be dealt with as follows and in the following order of priority: (i) where an amount has been retained and/or paid out of a distribution made to an Eligible Recipient pursuant to paragraph (b)(ii) above, an equivalent sum shall be paid to that Eligible Recipient; (ii) an amount has been set aside and/or paid from the Reserve Corp Scheme Creditors Fund or the Combined Corp Funds, or the Reserve plc Scheme Creditors Fund or the Combined plc Funds, an equivalent sum shall be returned to that fund (or any fund into which the contents of that fund have been transferred pursuant to this Agreement); and (iii) where an amount has been paid from the Escrow Tax Fund, an equivalent sum shall be returned to that fund, unless Corp has made a payment to the Escrow Trustee pursuant to sub-clause (10) (an "INDEMNITY PAYMENT"), in which case the amounts shall first be paid over to Corp to the extent of such Indemnity Payment. (9) The cost of any steps taken pursuant to this clause 12 ("COSTS") shall be met first out of the Escrow Tax Fund and subsequently: (a) before the end of the Waiting Period, out of the Reserve Corp Scheme Creditors Fund, or from the Reserve plc Scheme Creditors Fund as the case may be; and (b) after the end of the Waiting Period, out of the Combined Corp Funds or the Combined plc Funds, as the case may be. (10) Clause 9(4) of this Agreement shall not apply to any Tax Liability or any Costs of the Escrow Trustee and instead the following provisions shall apply: (a) Corp shall indemnify (on an after tax basis) the Escrow Trustee against any Tax Liability or any Costs (whether arising in relation to the Corp or plc Scheme) insofar as such Tax Liability or Costs cannot be met out of amounts retained for the purpose pursuant to sub-clause 11(2) or this clause 12. For the purposes of this sub-clause, a Tax Liability includes any interest or penalties thereon. (b) The Escrow Trustee shall promptly give notice to Corp if it appears to it that it may incur or suffer a potential Tax Liability. It shall demonstrate to Corp's reasonable satisfaction the extent to which (if at all) such Tax Liability or any Costs cannot be met out of the amounts referred to in paragraph (a) above. 658

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 7: ESCROW AND DISTRIBUTION AGREEMENT -------------------------------------------------------------------------------- (c) If it appears that Corp may be obliged to make payment to the Escrow Trustee in accordance with this sub-clause, Corp shall be entitled to resist the Tax Liability in the name of the Escrow Trustee and have the conduct of any proceedings relating to that Tax Liability, having indemnified the Escrow Trustee against all charges, costs and expenses which it might incur in resisting the Tax Liability. 13. TERMINATION (1) Promptly after each Escrow Account ceases to have any cash or securities credited to it, the Escrow Trustee shall, subject to obtaining the prior consent of the Supervisors, arrange for that Escrow Account to be closed. (2) Once all of the Escrow Accounts have been closed and the Distribution Agent's obligations fulfilled, the trusts set out in this Agreement shall be wound up. (3) Upon closure of all of the Escrow Accounts in accordance with the terms of this Agreement, each of the Escrow Trustee, the Distribution Agent and Bondholder Communications shall have no further duties, responsibilities or obligations hereunder save for such obligations as may have arisen prior to such closure, which obligations have not as at the time of such closure been fulfilled or discharged. 14. REPRESENTATIONS AND WARRANTIES (1) Each of the parties to this Agreement represents and warrants to each of the others that it has the capacity, power and authority to enter into this Agreement and that the obligations assumed by it (if any) are legal, valid and binding obligations on it. (2) Each of the parties to this Agreement represents and warrants to each of the others that neither the execution by it of, nor the performance by it of its respective obligations (if any) in accordance with the terms of, this Agreement will: (a) so far as that party is aware, violate or conflict with, or constitute a default under, any agreement or other obligation to which that party is subject or by which it is bound; or (b) so far as that party is aware, contravene or conflict with or constitute a violation of any provision of any law, rule, regulation, judgement, order or decree which is binding on it.

(4) Corp represents and warrants to each of the other parties to this Agreement that the Escrow Trustee has not carried on any business since the date of its incorporation to the date of this Agreement. 15. EXCLUSION OF PERSONAL LIABILITY Nothing in this Agreement shall impose any personal liability on the Supervisors or either of them but without prejudice to the Supervisors obligations under the Schemes. This clause is without prejudice to the provisions of clause 16. 16. EXCLUSION OF LIABILITY (1) None of the Supervisors, the Escrow Trustee, the Distribution Agent and Bondholder Communications (and their related parties (if any), delegates and agents appointed pursuant to the provisions of the Schemes) shall have any liability in respect of or arising from making the determinations or exercising any of the powers or performing any of the duties provided for in the Scheme or this Agreement or any matter relating to such determinations, powers or duties (including, without limitation, any payment made or not made to any person), other than as a direct consequence of its own wilful default, misfeasance, breach of duty or negligence (or that of its related parties (if any), delegates or agents).

We refer to the escrow and distribution agreement (the "ESCROW AGREEMENT") entered into on 27 March, 2003 between, inter alios, plc, Corp and Ancrane (the "COMPANY"). Except as otherwise provided in this letter, capitalised terms in this letter shall have the meaning ascribed to them in the Escrow Agreement and where there is a conflict, the definition in this letter shall prevail. 2. It is proposed that Corp and plc will each enter into a scheme of arrangement whereby, under the plc Scheme, the Scheme Claims of plc Scheme Creditors against plc will be compromised in exchange for a distribution of plc's assets pursuant to the plc Scheme and, under the Corp Scheme, the Scheme Claims of Corp Scheme Creditors against Corp will be compromised for a distribution of cash, new equity and new debt securities of Corp pursuant to the Corp Scheme. 3. The Company has repaid capital in specie, being all of its assets other than L100, to plc as contemplated in the scheme implementation deed (the "SCHEME IMPLEMENTATION DEED") entered into on 27 March, 2003 between, inter alios, plc, Corp and the Company. The Company is a Scheme Creditor of Corp for the purpose of the Corp Scheme and is also entitled to Corp Scheme Consideration and plc Scheme Consideration by virtue of its holding of Bonds. 4. (a) The Company hereby irrevocably directs Corp to deliver to plc any Scheme Consideration (as defined in the Corp Scheme) to which the Company is entitled pursuant to the Claim Form filed by it in the Corp Scheme.

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- OTHER ASSETS. The Issuer and each Guarantor organized or incorporated in England, the Republic of Ireland, Australia, Hong Kong, or any state of the United States will grant fixed and floating charges (or similar types of security) over all or substantially all of its assets (including Intellectual Property) to the Security Trustee, on behalf of the Note Trustees (for the benefit of the holders of the Notes) and the other Secured Creditors.

Such limitations will be set forth in the Security Trust and Intercreditor Deed and will be incorporated into the Guarantees of the Secured Obligations. See "Risk Factors -- Risks related to ownership of the New Shares, the New Notes and the Warrants -- The value of the guarantees and the collateral may be limited by applicable laws" in Section I, Part F.4. OTHER PROVISIONS RELATING TO THE TRANSACTION SECURITY AND THE SECURITY DOCUMENTS Prior to an Event of Default, the Indentures will permit the dispositions of Transaction Security in accordance with the Security Trust and Intercreditor Deed and in accordance with, to the extent applicable, or otherwise in compliance with, the Asset Sale covenants in the Indentures. In connection with the security arrangements in respect of the Notes, the Indentures will provide that the Issuer will not, and will not permit any of its Subsidiaries to, take or omit to take any action that could reasonably be expected to have the effect of adversely affecting the security granted over the Transaction Security pursuant to the Security Documents (but not the assets constituting the Transaction Security, unless otherwise required under the terms of the Indentures) to the Security Trustee on behalf of, inter alia, the Note Trustees for the benefit of the holders of the Notes, as described under the caption "Description of the Notes -- Certain Covenants -- Impairment of Security Interests". In addition, the Indentures will provide that the Issuer will, and will cause each of its Subsidiaries to, comply with all covenants and agreements contained in the Security Documents and the Security Trust and Intercreditor Deed the failure to comply with which would have a material adverse effect on the Liens created thereby. Any future Subsidiary of the Issuer that is required to Guarantee the Notes pursuant to the covenant described under the caption "Description of the Notes -- Certain Covenants -- Guarantor Coverage Requirements" or that otherwise Guarantees the Notes will be required to provide security for its obligations under the Guarantees of the Notes over such of its assets as are specified, and in accordance with the principles set forth, under the caption "Description of the Notes -- Certain Covenants -- Security Requirements with respect to Additional Guarantors". The Transaction Security will not include the Equity Interests in or properties or assets of certain Subsidiaries of the Issuer that on the Issue Date are not material. There can be no assurance that the proceeds of the sale or other 678

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- realization of the Transaction Security will be sufficient to satisfy the payments due on either Tranche of the Notes. Each Indenture provides that each holder of a Note, by its acceptance thereof, is deemed to have consented and agreed to the terms of the Security Documents and the Security Trust and Intercreditor Deed (including, without limitation, the provisions providing for foreclosure and release of the Transaction Security, as the same may be in effect or may be amended from time to time in accordance with their terms) and is deemed to authorise and direct (i) the Note Trustee, who shall in turn be authorized to instruct the Security Trustee, with respect to each of the Security Documents to which it is a party and the Security Trust and Intercreditor Deed, and (ii) the applicable Note Trustee, with respect to the Security Trust and Intercreditor Deed, to perform their respective obligations and exercise their respective rights thereunder in accordance therewith. DESCRIPTION OF THE NOTES PRINCIPAL, MATURITY AND INTEREST OF THE SENIOR NOTES Depending on the elections made by Scheme Creditors pursuant to the Restructuring, the Issuer will issue the Senior Notes initially in the form of Euro Senior Notes and/or Dollar Senior Notes and, if both Euro Senior Notes and Dollar Senior Notes are initially issued, Convertible Euro Senior Notes. The Sterling Equivalent of the aggregate principal amount of any and all Euro Senior Notes, Convertible Euro Senior Notes and Dollar Senior Notes as of the Issue Date shall be equal to L450 million. The Convertible Euro Senior Notes, if any, will be exchangeable into either Dollar Senior Notes or Euro Senior Notes at the election of the holder thereof. Pursuant to the Escrow and Distribution Agreement, the holder of the Convertible Euro Senior Notes will exchange such Notes for either Dollar Senior Notes or Euro Senior Notes prior to the distribution of such Notes to Scheme Creditors and after giving effect to valid elections of Scheme Creditors to whom such Notes are distributed. The Convertible Euro Senior Notes, if any, and the Euro Senior Notes, if any, shall be issued in denominations of E1.00 and integral multiples thereof. The Dollar Senior Notes, if any, shall be issued in denominations of US$1.00 and integral multiples thereof. The Senior Notes will mature on April 30, 2008 when they will be redeemed in cash at their outstanding principal amount together with any other amounts due thereunder. All payments of principal, premium, if any, interest, Additional Amounts, if any, and any other amounts due on the Senior Notes shall be made in the Relevant Currency. The Senior Notes will accrue interest from the Issue Date (or if interest has already been paid on the Senior Notes, from the most recent Senior Note Interest Payment Date to which interest has been paid), on their outstanding principal amount at the rate of 8 per cent. per annum payable quarterly in arrear on each Senior Note Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

If the Issuer elects to make payment in British pounds sterling, the amount payable in respect of each relevant Note shall be the Sterling Equivalent of the principal amount of the applicable Note (in Euro or United States dollars, as the case may be) multiplied by the applicable redemption price, multiplied by 1.005 and rounded (if necessary) to the nearest penny (with L0.005 being rounded upwards). Such calculation shall be made by the Issuer. If the Issuer so elects to pay British pounds sterling, the Issuer shall deliver to the Senior Note Trustee or the Junior Note Trustee, as applicable, on the applicable Repayment Date, an officers' certificate of the Issuer stating the amount in British pounds sterling to be paid in respect of each Euro or United States dollar principal amount of the applicable Notes, as the case may be, and stating that such calculation complies with the applicable clause of the applicable Indenture.

If the Issuer fails to make any payment on the Junior Notes when due as a result of the payment blockage provisions following the occurrence of a Payment Stop Event referred to above, such failure would constitute a Default and, after the expiration of any grace period, an Event of Default, under the Junior Note Indenture. See "Events of Default". If payment of the Junior Notes is accelerated because of an Event of Default, the Issuer shall promptly notify the Junior Note Trustee, the holders of the Junior Notes, the Senior Note Trustee and the holders of the Senior Notes.

For purposes of determining compliance with any sterling-denominated restriction on Indebtedness, if the Indebtedness incurred is denominated in a currency other than sterling, the amount of such Indebtedness will be the Sterling Equivalent, determined on the date of the incurrence of such Indebtedness (or, if later, the Issue Date).

The preceding sentence includes a phrase relating to the direct or indirect sale, assignment, transfer, conveyance, lease or other disposition of "all or substantially all" of the properties or assets of the Issuer and its Subsidiaries, taken as a whole. Although there is a limited body of case law interpreting the phrase "substantially all", there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of Senior Notes or Junior Notes to require the Issuer to redeem its Notes as a result of a sale, assignment, transfer, conveyance, lease or other disposition of less than all of the assets of the Issuer and its Subsidiaries, taken as a whole, to another Person or group may be uncertain. The Issuer will not permit any of its Subsidiaries, in a single transaction or through a series of related transactions, to, directly or indirectly, consolidate, merge or reorganize with or into another Person unless the provisions of clause (1) or (2) below are satisfied: (1) Such consolidation, merger or reorganization complies with the covenant described above under the caption "Description of the Notes -- Certain Covenants -- Asset Sales" or is excepted from the 693

For purposes of this covenant any US Core Business Sale will not be considered a sale of "all or substantially all" of the properties or assets of the Issuer and its Subsidiaries taken as a whole.

The Issuer will ensure that any of its Subsidiaries that guarantees any of the Senior Notes or the Junior Notes after the Issue Date: (1) executes and delivers supplemental indentures to the Senior Note Indenture and the Junior Note Indenture pursuant to which it becomes a Guarantor of the Notes issued thereunder, in each case, in form and substance reasonably satisfactory to the applicable Note Trustee; (2) executes and delivers a Guarantee (which, for the avoidance of doubt, may be an accession letter to the Guarantee) of all outstanding Notes in form and substance reasonably satisfactory to the applicable Note Trustee; and (3) becomes a party to the Security Trust and Intercreditor Deed. On or prior to the date on which any Additional Guarantor executes a supplemental indenture to guarantee the Notes, the Issuer shall, and shall procure that its relevant Subsidiaries (including the Additional Guarantor), execute and deliver to the Security Trustee, on behalf of the Note Trustees (for the benefit of the holders of the Notes) and the other Secured Creditors, Security Documents that provide security (the "New Security") for the obligations of such Additional Guarantor under its Guarantees of the Notes and such other Secured Obligations of such Additional Guarantor, which complies with the requirements set forth in this covenant, including 700

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- clauses (1) to (8) in the third succeeding paragraph. The Issuer shall deliver, on each date on which an Additional Guarantor executes a supplemental indenture and a Guarantee of the Notes, to the Senior Note Trustee (in the case of the Senior Notes) and the Junior Note Trustee (in the case of the Junior Notes), an officers' certificate stating that the Issuer and its relevant Subsidiaries have complied with this covenant and an opinion of counsel in form and substance reasonably satisfactory to the applicable Note Trustee with respect to such Guarantee and any New Security. The New Security shall be subject to the general principles in clause (4) of the second succeeding paragraph and shall consist of: (1) share pledges over the Equity Interests in such Additional Guarantor; (2) fixed security over any key freehold or leasehold real property (determined by reference to whether such property is key to the business of the Group as a whole) owned by such Additional Guarantor; (3) with respect to any Additional Guarantor that is incorporated or organized under the laws of England, the Republic of Ireland, any state of the United States, Australia, Canada or Hong Kong or any other jurisdiction in which a floating charge (or similar security) is recognized, floating charges (or similar types of security) over all or substantially all of the assets of such Additional Guarantor; (4) with respect to any Additional Guarantor that is incorporated or organized under the laws of Italy, Germany, or any other jurisdiction in which a floating charge (or similar security) is not recognized, security over all material assets (including Equity Interests in any Wholly-Owned Subsidiary of such Additional Guarantor that is directly owned by such Additional Guarantor, receivables, bank accounts, Intellectual Property and movables) of such Additional Guarantor. In addition, the Issuer shall, and shall cause each of its relevant Subsidiaries to, take all necessary action to ensure that the organizational documents of any Subsidiary of the Issuer whose Equity Interests are the subject of a share pledge shall not contain any restrictions or limitations on the transfer of the pledged Equity Interests, including any transfer pursuant to any enforcement of such share pledge. For the purposes of this covenant: (1) Share Pledges. With respect to share pledges over Equity Interests, unless required by applicable law as the only means of procuring a security interest but provided also that the Security Trustee shall not be required to accept such transfer if it may be prejudiced thereby, the taking of security shall not require transfer of legal title to the pledged Equity Interests to the Security Trustee. Until the occurrence of an Enforcement Event, (a) the pledgor of Equity Interests constituting New Security shall be permitted to exercise voting rights with respect to the Equity Interests pledged in such manner as it sees fit, provided that such exercise would not constitute a Default under any Relevant Document; (b) the pledgor of the Equity Interests constituting the New Security shall be permitted to receive and retain dividends and other distributions on such Equity Interests; and (c) to the extent that legal title to the pledged Equity Interests is vested in the Security Trustee, the Security Trustee, as the holder of such Equity Interests, shall (subject to the terms of the Security Trust and Intercreditor Deed) be required to pay all dividends and distributions on such Equity Interests and exercise all voting and other rights with respect to such Equity Interests in such manner as the pledgor of such Equity Interests may reasonably direct, provided that any such action by the Security Trustee would not result in a Default under any Relevant Document. (2) Bank Accounts. With respect to bank accounts, all security over such accounts shall permit the relevant Additional Guarantor to operate those accounts freely without reference to the Security Trustee prior to a notice being served by the Security Trustee following the occurrence of an Enforcement Event. (3) Notification/Perfection Requirements. With respect to security over the following assets, the notification/perfection requirement shall be as follows: (a) Initial Notification/Perfection Requirements: In relation to any jurisdiction where New Security is to be provided, the relevant Additional Guarantor shall (where such action is 701

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- required for the creation, continued effectiveness or perfection of the New Security), on the date such Additional Guarantor executes any Relevant Document: (i) procure the endorsement of the share pledge on the Additional Guarantor's share register or share certificates or deliver share certificates or blank stock transfer forms and satisfy other notification or perfection requirements; (ii) provide a list of bank accounts and serve notices of the creation of the relevant security interest (or permit the Security Trustee to serve notices) to account banks; (iii) (in Italy and Germany and in any other jurisdiction the law of which may impose similar obligations on an Additional Guarantor) send to the Security Trustee details of pledged receivable claims; (iv) where relevant, notify the insurer of the assignment or charge of an insurance policy; and (v) deliver to the Security Trustee real estate documents of title. (b) Ongoing Notification/Perfection Requirements in Italy: Any Additional Guarantor organized or incorporated under Italian law shall, within ten (10) London Business Days of the end of each calendar quarter, provide to the Security Trustee, (x) the most recent monthly bank statements from each account bank, (y) a list of all receivable claims together with contact details of all debtors, and, within ten (10) London Business Days of the acquisition of any shares, carry out the steps required to perfect security over future shareholdings. Any Additional Guarantor incorporated under the law of a jurisdiction where similar on-going requirements apply to the creation, continued effectiveness or perfection of New Security will comply with such requirements. (4) General Principles. Subject to the terms of the Security Trust and Intercreditor Deed, any security shall (to the extent legally possible and without the Security Trustee or the directors of the relevant Subsidiary being exposed to material personal risk) secure the obligations of such Additional Guarantor under the Relevant Documents and shall (to the extent legally possible and subject to the other provisions below) create valid, perfected and first priority security over such assets. With regard to any security to be provided by an Additional Guarantor, due regard shall be had to: (a) any risk that the Security Trustee or the directors of a Subsidiary being asked to provide or receive, as the case may be, security could be held to be in breach of applicable corporate, criminal or other law in providing such security; (b) the practicality and costs involved in taking any such security; (c) the value of the proposed security to the Secured Creditors in light of the whole of the security already provided to them at such time; and (d) legitimate operational requirements of the Additional Guarantor; provided that if security is to be provided by an Additional Guarantor in any jurisdiction where security has been taken on the Issue Date, such Additional Guarantor shall grant the same types of security (assuming such Additional Guarantor has the same types of assets) in such jurisdiction as the Guarantors as of the Issue Date in that jurisdiction unless there has been an amendment to or change in the laws, regulations or rulings of such jurisdiction, or any amendment to or change in any position concerning the administration, application or interpretation of such laws, regulations or rulings, which amendment or change has become effective on or after the Issue Date and is relevant to the granting of security in such jurisdiction (in which case the security granted by such Additional Guarantor shall take into account any such amendment or change). In the event that the terms of the Indentures and the Notes do not restrict the freedom of an Additional Guarantor to deal in assets over which security has been granted, the Additional 702

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- Guarantor shall have freedom to deal under the terms of the Security Documents granting New Security. (5) Security Trustee. To the extent possible, all security shall be granted in favor of the Security Trustee and not other Secured Creditors individually. "Parallel debt" provisions shall be used, which provisions shall be as contained in the Security Trust and Intercreditor Deed and not the Security Documents granting New Security. To the extent possible, no action shall be required to be taken in relation to New Security when any Secured Creditor transfers any of its participation in any Relevant Document to another Person. (6) No Commercial Provisions. The provisions of the Security Documents granting New Security shall operate only so as to create and preserve effective security and shall not impose commercial undertakings or include any provisions which are credit protections or which seek to preserve the value of assets or any indemnities, unless those are legally required for the creation, continued effectiveness or perfection of the New Security. Representations and further assurance provisions shall be included in the Security Documents granting New Security to the extent necessary or desirable to create security under applicable law. Additional undertakings shall only be included if they will not unduly interfere with the normal running of the business of such Additional Guarantor. (7) Enforcement. All Transaction Security shall only be enforceable upon an Enforcement Event. Security Documents granting New Security shall include any limitations on enforcement of security which are needed in order to give effect to the general principles in clause (4) above. (8) Release of Security. The circumstances under which the Security Trustee shall be required to release New Security, which shall be as set forth in the Security Trust and Intercreditor Deed, shall not be included in the Security Documents granting New Security unless pursuant to applicable law those provisions must be set forth in such Security Documents in order to give effect to the provisions set forth in the Security Trust and Intercreditor Deed or required by applicable law and any such provisions in any Security Document shall be consistent with those set forth in the Security Trust and Intercreditor Deed. Release of Guarantees and Collateral. The Guarantee of the Notes by any Guarantor under each of the Indentures will be released upon a sale or other disposition of all of the Equity Interests of such Guarantor by the Issuer or a Subsidiary of the Issuer, in compliance, to the extent applicable, with the covenant entitled "Description of the Notes -- Certain Covenants -- Asset Sales". In addition, each of the Guarantors will be discharged from its obligations in respect of its Guarantee of the Notes in the circumstances set forth under "Satisfaction and Discharge" below. Pursuant to the terms of the Security Trust and Intercreditor Deed, the Transaction Security relating to the Guarantee of the Notes by any Guarantor under each of the Indentures will be released upon the sale or other disposition of the assets constituting such Transaction Security by the Issuer or any of its Subsidiaries in compliance, to the extent applicable, with the covenant entitled "Description of the Notes -- Certain Covenants -- Asset Sales". Notwithstanding the foregoing, the Guarantee of the Notes by MCHI and any Transaction Security related thereto shall be released at the request of the Issuer upon certification provided by the Issuer to the Security Trustee, the Senior Note Trustee and Junior Note Trustee that, subject to such releases, MCHI has completed all distributions to the stockholders of MCHI pursuant to and in accordance with the MCHI Plan of Liquidation and Dissolution. Limitations on Issuances of Guarantees of Indebtedness. The Issuer will not permit any of its Subsidiaries that is not a Guarantor to, directly or indirectly, Guarantee any Indebtedness of the Issuer or any Guarantor unless such Subsidiary simultaneously executes and delivers supplemental indentures in form and substance satisfactory to the applicable Note Trustee providing for the Guarantee of all outstanding Senior Notes and Junior Notes by such Subsidiary, which Guarantees will, subject to the terms of the Security Trust and Intercreditor Deed, be at least pari passu with such Subsidiary's Guarantee of such other Indebtedness, and be secured by New Security in 703

Notwithstanding any other provision in the Senior Note Indenture, each holder of the Senior Notes shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any), interest, if any, and Additional Amounts, if any, on the Senior Notes and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such holder. The Issuer is required to deliver to the Senior Note Trustee a semi-annual statement regarding compliance with the Senior Note Indenture. Furthermore, upon becoming aware of any Default or Event of Default under the Senior Note Indenture, the Issuer is required to deliver to the Senior Note Trustee and Security Trustee a statement specifying such Default or Event of Default. The Senior Note Trustee shall give the holders of the Senior Notes notice of each Default under the Senior Note Indenture known to such Trustee, within 30 days after the occurrence thereof, as and to the extent provided by the Trust Indenture Act, unless such Default shall have been cured or waived.

Furthermore, upon becoming aware of any Default or Event of Default under the Junior Note Indenture, the Issuer is required to deliver to the Junior Note Trustee and Security Trustee a statement specifying such Default or Event of Default. The Junior Note Trustee shall give the holders of the Junior Notes notice of each Default under the Junior Note Indenture known to such Trustee, within 30 days after the occurrence thereof, as and to the extent provided by the Trust Indenture Act, unless such Default shall have been cured or waived. FORM OF NOTES Each Series of each Tranche of Notes will initially be represented by one or more global notes in bearer form without interest coupons attached (each a "Global Note" and together the "Global Notes"). Title to the Global Notes will pass by delivery. The holder of any certificate representing any Series of any Tranche of Notes, including any Global Note (the "holder"), is the person that has possession of the certificate, in the case of a bearer certificate, and the person in whose name the certificate is registered, in the case of a certificate in registered form. The Global Notes will be deposited on issue with The Bank of New York, as depositary (the "Depositary") under the Deposit Agreement. Under the Deposit Agreement, the Depositary will issue to DTC, Euroclear and/or Clearstream certificateless depositary interests, which together represent a 100 per cent. interest in each underlying Global Note. The certificateless depositary interests will be registered in the name of Cede & Co., as nominee of DTC (with respect to certificateless depositary interests issued to DTC) or the nominee of a common depositary for Euroclear and Clearstream (with respect to certificateless depositary interests issued to Euroclear and/or Clearstream). Upon acceptance by DTC, Euroclear and/or Clearstream of a certificateless depositary interest for entry into their respective book-entry settlement systems, beneficial interests in the certificateless depositary interests (the "Book-Entry Interests") will be issued by DTC, Euroclear and/or Clearstream and traded through their respective book-entry systems. The Book-Entry Interests will not be held in definitive form. Book-Entry Interests will be held by or through persons that have accounts with DTC, Euroclear and/or Clearstream ("direct participants") or persons that hold interests through direct participants ("indirect participants" and, together with direct participants, "participants"). The laws of some jurisdictions, including certain states of the United States, may require that certain investors in securities take physical delivery of such securities in definitive form. The foregoing limitations may impair the ability of investors to own, transfer or pledge Book-Entry Interests. In addition, while the Notes are in global form, "holders" of Book-Entry Interests will not be considered the owners or "holders" of Notes for any purpose. Ownership of the Book-Entry Interests will be shown on, and the transfer of ownership will be effected only through, records maintained in book-entry form by DTC, Euroclear, Clearstream and their participants. Book-Entry Interests will be transferable only as units in the same authorized denominations as the Notes of the Series to which they correspond. Unless any Series of Notes is exchanged in whole or in part for other securities of the 716

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- Issuer, or the applicable Global Note is exchanged for Notes in definitive registered form ("Definitive Registered Notes"), the certificateless depositary interests representing Notes of a Series held by DTC, Euroclear and/or Clearstream may not be transferred except as a whole between DTC, Euroclear and/or Clearstream, a nominee of DTC, the nominee of a common depositary for Euroclear and Clearstream, or their respective successors. So long as the Depositary or its nominee is the holder of the Global Note(s) representing Notes of a Series, the Depositary or its nominee will be considered the sole holder of the Global Note(s) for all purposes under the applicable Indenture. Except as described below under the caption "The Deposit Agreement -- Issuance of Definitive Registered Notes and Termination of the Deposit Agreement", no participant or other person will be entitled to have Notes registered in its name, receive or be entitled to receive physical delivery of Definitive Registered Notes or be considered the owner or holder of the Notes under the applicable Indenture or the Deposit Agreement. Accordingly, each person owning a Book-Entry Interest must rely on the procedures of the Depositary and DTC, Euroclear and/or Clearstream and, if the person is not a direct participant in DTC, Euroclear and/or Clearstream, on the procedures of the direct participant or other securities intermediary through which the person owns its interest, to exercise any rights and obligations of a holder under the applicable Indenture, the applicable Series of Notes or the Deposit Agreement. The Issuer will not impose any fees or other charges in respect of the Notes; however, holders of the Book-Entry Interests may incur fees normally payable in respect of the maintenance and operation of accounts in DTC, Euroclear and/or Clearstream. None of the Issuer, the Guarantors, the Note Trustees, the Security Trustee, the Depositary, any Paying Agent or any of their agents will have any responsibility or liability for any aspect of the records relating to or payments made on account of Book-Entry Interests. PAYMENTS ON THE GLOBAL NOTES. Payments of any amounts relating to any Global Note will be made through the Paying Agents to the Depositary, as the holder of the Global Note. The Issuer and its agents will be discharged, by payment to or to the order of the Depositary, from any responsibility or liability for each amount paid in this manner. Under the Deposit Agreement, the Depositary will pay an amount equal to all these payments to DTC, Euroclear and/or Clearstream, except as described below. None of the Issuer, the Guarantors, the applicable Note Trustee, the Security Trustee, the Depositary, any Paying Agent or any of their agents will have any responsibility or liability for any aspect of the records relating to payments made by DTC, Euroclear and/or Clearstream or their participants on account of Book-Entry Interests or for maintaining, supervising or reviewing any records relating to the Book-Entry Interests. A holder of a Book-Entry Interest issued by DTC denominated or repayable in a Relevant Currency other than US dollars electing to receive payments of principal or interest, if any, in a currency other than US dollars must notify the DTC participant through which its interest is held on or prior to the applicable record date, in the case of a payment of interest, and on or prior to the twelfth day prior to the date of payment of principal, in the case of principal, of such beneficial owner's election to receive all or a portion of such payment in a Relevant Currency other than US dollars, together with wire transfer payment instructions to an account in the Relevant Currency. Any such election in respect of a payment of principal or interest shall be irrevocable. In the case of a payment of interest, such DTC participant must notify DTC of such election on or prior to the third Business Day after such record date. DTC will notify the Paying Agent of such election on or prior to the fifth Business Day after such record date for any payment of interest. In the case of a payment of principal, such DTC participant must notify DTC of such election on or prior to the twelfth day prior to the payment of principal. DTC will notify the Paying Agent of such election on or prior to the tenth Business Day prior to the payment of principal. If complete instructions are received by the DTC participant and forwarded by the DTC participant to DTC, and by DTC to the Paying Agent, on or prior to such dates, the beneficial owner will receive payments of principal and or interest in the Relevant Currency; otherwise only US dollar payments will be made by the Paying Agent through DTC. If any holder of a certificateless depositary interest issued by DTC does not elect to receive principal or interest payments in the Relevant Currency in accordance with the rules and procedures of DTC, such payments will be made in US dollars. Conversion of the Relevant Currency into US dollars will be made by the Depositary. In particular, holders of certificateless depositary interests issued by DTC should be aware that 717

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- the Depositary has the right to deduct from payments made in US dollars all costs of converting amounts in the Relevant Currency to US dollars. INFORMATION REGARDING DTC, EUROCLEAR AND CLEARSTREAM DTC, Euroclear and Clearstream have advised the Issuer of the following information: DTC. DTC is: - a limited-purpose trust company organized under the New York Banking Law; - a "banking organization" within the meaning of the New York Banking Law; - a member of the Federal Reserve System; - a "clearing corporation" within the meaning of the New York Uniform Commercial Code; and - a "clearing agency" registered under Section 17A of the US Exchange Act. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of transactions among its participants in these securities through electronic book-entry changes in accounts of the participants, eliminating the need for physical movement of securities certificates. Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Some of these participants, along with some of their representatives and others, own DTC. Access to the DTC book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The Issuer understands that DTC will take any action permitted to be taken by a holder of a beneficial interest in the applicable Series of Notes only at the direction of participants to whose account with DTC Book-Entry Interests are credited and only for the principal amount of the Book-Entry Interests as to which these participants have given such direction. EUROCLEAR AND CLEARSTREAM. Some beneficial owners of the Notes may hold Book-Entry Interests through their accounts with Euroclear and Clearstream. Each of Euroclear and Clearstream holds securities for its account holders and facilitates the clearance and settlement of transactions by electronic book-entry transfers between its account holders, eliminating the need for physical movements of certificates and any risk from lack of simultaneous transfers of securities. Euroclear and Clearstream provide various services including safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Euroclear and Clearstream also deal with domestic securities markets in several countries through established depositary and custodial relationships. Euroclear and Clearstream have established an electronic bridge between their two systems across which their account holders may settle trades with each other. Account holders in Euroclear and Clearstream are world-wide financial institutions including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. Indirect access to Euroclear and Clearstream is available to other institutions that clear through or maintain a custodial relationship with an account holder of either system. Account holders' overall contractual relations with Euroclear and Clearstream are governed by the respective rules and operating procedures of Euroclear and Clearstream, and any applicable laws. Euroclear and Clearstream act under these rules and operating procedures only on behalf of their respective account holders. They have no record of or relationship with persons holding through their respective account holders. GLOBAL CLEARANCE AND SETTLEMENT UNDER THE BOOK-ENTRY SYSTEM The Book-Entry Interests representing interests in the Global Notes of a Series are expected to be listed on the London Stock Exchange plc. Book-Entry Interests issued by DTC are expected to trade in DTC's same-day funds settlement system, and secondary market trading activity in such Book-Entry Interests will, therefore, be required by DTC to be settled in immediately available funds. Book-Entry Interests issued by Euroclear and/or 718

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- Clearstream are expected to settle in same-day funds. The Issuer expects that secondary trading in any Definitive Registered Notes will also be settled in immediately available funds. Cross-market transfers between participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be done through DTC in accordance with DTC's rules on behalf of each of Euroclear or Clearstream by its common depository; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream by the counterparty in such system in accordance with the rules and regulations and within the established deadlines of such system (Brussels time). Euroclear or Clearstream will, if the transaction meets its settlement requirements, deliver instructions to the common depositary to take action to effect final settlement on its behalf by delivering or receiving Book-Entry Interests by DTC, and making and receiving payment in accordance with normal procedures for same-day funds settlement application to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the common depository. Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing a Book-Entry Interest from a participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear and Clearstream as a result of a sale of a Book-Entry Interest by or through a Euroclear or Clearstream participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date. Although DTC, Euroclear and Clearstream currently follow the foregoing procedures in order to facilitate transfers of Book-Entry Interests among participants in DTC, Euroclear and Clearstream, as the case may be, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued or modified at any time. None of the Issuer, the Guarantors, the Note Trustees, the Security Trustee, the Depositary, any Paying Agent or any of their agents will have any responsibility for the performance of DTC, Euroclear or Clearstream or their respective participants or indirect participants, of their respective obligations under the rules and procedures governing their operations. SECONDARY MARKET TRADING The Book-Entry Interests will trade through participants of DTC, Euroclear and/or Clearstream and will settle in same-day funds. Since the purchaser determines the place of delivery, it is important to establish at the time of trading of any Book-Entry Interests where both the purchaser's and the seller's accounts are located to ensure that the settlement can be made on the desired value date. THE DEPOSIT AGREEMENT REDEMPTION. In the event that a Global Note or any portion of a Global Note is redeemed, the Depositary will redeem an equal amount of the certificateless depositary interest or interests issued by DTC, Euroclear and/or Clearstream. ISSUANCE OF DEFINITIVE REGISTERED NOTES AND TERMINATION OF THE DEPOSIT AGREEMENT. So long as DTC, Euroclear and/or Clearstream holds the certificateless depositary interest or interests representing Notes of a Series, the Book-Entry Interests (and corresponding Global Notes) will not be exchangeable for Definitive Registered Notes except if: - DTC, Euroclear or Clearstream notifies the Depositary that it is unwilling or unable to continue to hold the certificateless depositary interest or interests, or if at any time DTC is unable to or ceases to be a clearing agency registered under the US Exchange Act, and in either case a successor to DTC, Euroclear and/or Clearstream, as applicable, is not appointed by the Depositary within 120 days; - the Depositary notifies the Issuer and the relevant Note Trustee that it is unwilling or unable to continue to act as Depositary, and the Issuer is unable to appoint a successor Depositary within 120 days; or 719

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- - if so requested by either DTC, Euroclear, Clearstream, the Issuer or the applicable Note Trustee, in the event of a winding-up of the Issuer or an Event of Default, as defined in the applicable Indenture, has occurred and is continuing. To receive or direct the delivery of possession of any Definitive Registered Notes, each person owning a Book-Entry Interest must rely exclusively on the provisions of the Deposit Agreement, the rules or procedures of DTC, Euroclear and/or Clearstream and any agreement with any participant or any other securities intermediary through which that person holds its interest. If Definitive Registered Notes are issued by the Issuer in exchange for a particular Global Note, the Depositary will promptly notify DTC, Euroclear and/or Clearstream that the corresponding Global Note will be exchanged in whole or in part for Definitive Registered Notes. Definitive Registered Notes will be issued in such names and amounts as DTC, Euroclear and/or Clearstream may specify upon cancellation of the corresponding certificateless depositary interests and all Book-Entry Interests relating to the certificateless depositary interests. The Depositary will promptly surrender the corresponding Global Note held by it to the relevant Note Trustee in connection with such exchange for cancellation. Any Definitive Registered Notes will be issued in registered form in the same authorized denominations as the applicable Notes of the Series to which they correspond.

The Issuer will agree to indemnify the Depositary against certain liabilities incurred by it under the Deposit Agreement. ADDITIONAL AMOUNTS All payments made under, or with respect to, the Senior Notes, the Junior Notes and the Guarantees thereof will be made free and clear of, and without withholding or deduction for or on account of, any present or future Taxes, unless the Issuer or any Guarantor is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If the Issuer or any Guarantor is required to withhold or deduct any amount for, or on account of, Taxes imposed by the United Kingdom or by any other jurisdiction in which the Issuer or any Guarantor is organized or resident for Tax purposes or any political subdivision thereof or any Taxing Authority therein (each, a "Relevant Taxing Jurisdiction"), from any payment made under or with respect to the Senior Notes, the Junior Notes or the Guarantees thereof, the Issuer or the applicable Guarantor will pay such additional amounts ("Additional Amounts") as may be necessary so that the net amount received by each holder (including Additional Amounts) after such withholding or deduction will equal the amount the holder would have received had no such withholding or deduction been required; provided, however, that no Additional Amounts will be payable with respect to any Tax: (a) that would not have been imposed, payable or due: (1) but for the existence of any connection between the holder (or the Beneficial Owner of, or Person ultimately entitled to obtain an interest in, the Senior Notes, the Junior Notes or the Guarantees thereof) and the Relevant Taxing Jurisdiction (including being a citizen or resident or national of, or carrying on a trade or business or maintaining a permanent establishment or fixed base in, or being physically present in, or having made an election, the effect of which is to subject the holder to such Taxes in, in each case whether by himself or through an agent, of the Relevant Taxing Jurisdiction) other than the mere holding of the Senior Notes, the Junior Notes or the Guarantees thereof, as applicable, or enforcement of rights thereunder or the receipt of payments in respect thereof; (2) if the presentation of the Senior Notes or the Junior Notes, as applicable, (where presentation is required) for payment had occurred within 30 days after the date such payment was due and payable or was duly provided for, whichever is later except to the extent that the holder 721

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- of such Notes would have been entitled to such Additional Amounts on presenting such Notes for payment on the last day of such period of 30 days; or (b) on a payment to an individual where such withholding or deduction is required to be made pursuant to any European Union Directive on the taxation of savings implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 or any law implementing or complying with or introduced in order to conform to, such Directive; or (c) if the holder of the Senior Note or Junior Note, as applicable, would have been able to avoid such withholding or deduction by presenting the Senior Note or the Junior Note, as applicable, to another Paying Agent in a money-center in a member state of the European Union; or (d) where the payment of such Additional Amounts is prevented by any combination of (a), (b) or (c). With respect to paragraph (c) above, the Issuer will undertake to ensure that it maintains a paying agent in a European Union member state that will not be obliged to withhold or deduct tax pursuant to the European Union Directive. If the Issuer or any Guarantor will be obliged to pay Additional Amounts with respect to any payment under or with respect to the Senior Notes or the Junior Notes, or the Guarantees thereof, the Issuer or any Guarantor will deliver to the applicable Note Trustee at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment date, in which case the Issuer or any Guarantor shall notify the applicable Note Trustee promptly thereafter) an officers' certificate stating the fact that Additional Amounts will be payable and the amount so payable. The officers' certificate must also set forth any other information necessary to enable the Paying Agent to pay Additional Amounts to holders on the relevant payment date. The Issuer or any Guarantor will make all required withholdings and deductions and will remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Issuer and such Guarantor will use their respective reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Taxing Authority. The Issuer or any Guarantor will furnish to the applicable Note Trustee, within 60 days after the date the payment of any Taxes so deducted or withheld is due pursuant to applicable law, certified copies of tax receipts evidencing payment by the Issuer or any Guarantor, or if, notwithstanding the Issuer's and such Guarantor's efforts to obtain receipts, receipts are not obtained, other evidence of payments by the Issuer or such Guarantor. The Issuer or any Guarantor will pay any stamp duty reserve tax, stamp duty, court or documentary taxes, or any other excise or property taxes, charges or similar levies or Taxes which arise from the initial execution, delivery or registration of the Senior Notes or the Junior Notes, as applicable, and the enforcement of such Notes following the occurrence of any Event of Default with respect to such Notes. Whenever in the applicable Indenture or in any Tranche of Notes there is mentioned, in any context, the payment of amounts based upon the principal amount of such Notes or of principal, interest, premium, if any, or of any other amount payable under, or with respect to, the applicable Tranche of Notes, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. AMENDMENT, SUPPLEMENT AND WAIVER The Senior Note Indenture and the Junior Note Indenture each contain a covenant that the Issuer will not, and will not permit any of its Subsidiaries to, amend, modify or supplement the Junior Note Indenture, the Junior Notes or the Guarantee thereof while any Senior Notes are outstanding, with limited exceptions, as described under the caption "Description of the Notes -- Certain Covenants -- Restrictions on Amendments". In addition, under the Security Trust and Intercreditor Deed, the Issuer and the Junior Note Trustee will agree that until all Secured Obligations arising under the Senior Notes and the Senior Note Indenture have been discharged in full, no amendments to the Junior Notes or the Junior Note Indenture are permitted, with limited exceptions, as described under the caption "The Security Trust and Intercreditor Deed -- Amendments, Consents and 722

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 8: SUMMARY OF THE TERMS OF THE NEW SENIOR NOTES AND THE NEW JUNIOR NOTES -------------------------------------------------------------------------------- If any Tranche of Notes is to be redeemed in part only, the notice of redemption that relates to such Tranche of Notes will state the portion of the principal amount of such Tranche of Notes that is to be redeemed.

For Notes of a Tranche which are represented by certificateless depositary interests held on behalf of DTC, Euroclear and/or Clearstream, notices may be given by delivery of the notices to DTC, Euroclear and/or Clearstream for communication to entitled account holders in substitution for the aforesaid notices. SATISFACTION AND DISCHARGE The applicable Indenture will be discharged and will cease to be of further effect as to all Notes issued thereunder, when: (1) either: (a) all such Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Issuer or discharged from such trust, have been delivered to the applicable Note Trustee for cancellation; or (b) all such Notes that have not been delivered to the applicable Note Trustee for cancellation: (i) have become due and payable by reason of the giving or delivery of a notice of redemption or otherwise, (ii) will become due and payable at their Stated Maturity within one year, or (iii) are to be called for redemption within one year under arrangements satisfactory to the applicable Note Trustee for the giving of notice of redemption, and in the case of (i), (ii) or (iii) above the Issuer has irrevocably deposited or caused to be deposited with the applicable Note Trustee as trust funds in trust solely for the benefit of the holders cash denominated in the Relevant Currency, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the applicable Tranche of Notes not delivered to the applicable Note Trustee for cancellation, including principal and premium, if any, and accrued interest and Additional Amounts, if any, to the date of maturity or redemption, as the case may be; (2) no Default or Event of Default with respect to such Notes has occurred and is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or any Subsidiary of the Issuer is a party or by which the Issuer or any Subsidiary of the Issuer is bound; (3) the Issuer has paid or caused to be paid all sums payable by it under the applicable Indenture; and (4) if applicable, the Issuer has delivered irrevocable instructions to the applicable Note Trustee under the applicable Indenture to apply the deposited money toward the payment of such Notes at maturity or the Repayment Date, as the case may be. In addition, the Issuer must deliver an officers' certificate and an opinion of counsel to the applicable Note Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. PARALLEL DEBT OBLIGATION Each Indenture will provide that each Obligor agrees and covenants with the applicable Note Trustee by way of an abstract acknowledgement of debt that, notwithstanding anything to the contrary in the applicable Indenture, the applicable Tranche of Notes or the Guarantee thereof, it shall pay to the applicable Note Trustee sums equal to, and in the currency or currencies of, the amounts owed by such Obligor from time to time to the holders of the applicable Tranche of Notes under the applicable Indenture, the applicable Tranche of Notes and the Guarantee thereof (with respect to each Tranche of Notes, the "Principal Obligations"), as and when the same fall due for 725

The rights of the holders of the applicable Tranche of Notes to receive payment of the applicable Principal Obligations are several from the rights of the applicable Note Trustee to receive the applicable Parallel Obligations, provided that the payment by an Obligor of its Parallel Obligations with respect to a Tranche of Notes to the applicable Note Trustee in accordance with the applicable Indenture shall be a good discharge of the corresponding Principal Obligations owed by it and the payment by an Obligor of its Principal Obligations with respect a Tranche of Notes in accordance with the provisions of the applicable Indenture, the applicable Tranche of Notes and the Guarantee thereof shall be a good discharge of the corresponding Parallel Obligations owed to the applicable Note Trustee under the applicable Indenture. In the event of a good discharge of any Principal Obligations with respect to a Tranche of Notes the applicable Trustee shall not be entitled to demand payment of the corresponding Parallel Obligations and such Parallel Obligations shall be discharged to the same extent. In the event of a good discharge of any Parallel Obligations with respect to a Tranche of Notes, the holders of such Tranche of Notes shall not be entitled to demand payment of the corresponding Principal Obligations and such Principal Obligations shall be discharged to the same extent. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS No past, present or future director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, will have any liability for any obligations of the Issuer or such Guarantor under (a) the Senior Notes, the Senior Note Indenture, or the Guarantee of the Senior Notes, or (b) the Junior Notes, the Junior Note Indenture, or the Guarantee of the Junior Notes, respectively, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of a Note by accepting such Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the applicable Tranche of Notes. The waiver may not be effective to waive liabilities under the federal securities laws of the United States. CONCERNING THE NOTE TRUSTEES The Senior Note Trustee will be Law Debenture Trust Company of New York. The Junior Note Trustee will be JPMorgan Chase Bank. If the applicable Note Trustee becomes a creditor of the Issuer or any Subsidiary of the Issuer, the applicable Indenture limits its right to obtain payment of claims in certain cases, or to realise on certain property received in respect of any such claim as security or otherwise. The applicable Note Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days or resign. Each Indenture will provide that the applicable Note Trustee shall be entitled to accept any certificate delivered to it by the Issuer, and any opinion of counsel to the Issuer delivered to it, pursuant to such Indenture as sufficient evidence of the satisfaction of the applicable conditions in, and/or compliance with the applicable requirements of, the applicable Indenture and, in the absence of manifest error, no liability to any holder of a Note will attach to the applicable Note Trustee for so relying on any such certificate or opinion of counsel. LISTING Applications will be made for the Notes of each Tranche to be admitted to listing on the Official List of the UK Listing Authority and to trading on the London Stock Exchange. 726

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- PART II -- EXPLANATION FOR EXCLUSIONS AT CORP LEVEL GENERAL Despite the fact that the Corp Scheme is intended to be an all-creditor scheme, it has become necessary to exclude certain categories of creditor. The commercial rationale for excluding such creditors is to ensure that the Restructuring is successful and that the Group can continue operations going forward with the minimum of disruption once the Corp Scheme becomes effective. The claims of certain creditors have been excluded from the Corp Scheme for a variety of reasons as follows: a. that Corp will continue to carry on business as the holding company of a very substantial group of companies, comprising some 300 subsidiaries, with an aggregate turnover, in the six months ended 31 December 2002, of approximately L1.5 billion and it is necessary to exclude such claims to ensure the continuing viability of the restructured Corp Group -- those categories which are attributable (in whole or in part) to the continuation of the restructured group are Categories 1, 2, 3, 4, 5, 6, 7, 8, 11, 15 and 16; b. that the only type of scheme which Corp's principal financial creditors are prepared to support is a scheme which involves an immediate distribution calculated by reference to specific reserves; and an immediate distribution which consists of the whole amount to which, when calculated by reference to those specific reserves, an admitted scheme creditor is entitled -- the categories which are attributable (in whole or in part) to the nature of the proposed Scheme are Categories 2, 3, 4, 5, 9, 17 and 18; c. that certain claims would be preferential if Corp were to be wound up -- the categories which are attributable (in whole or in part) to the preferential nature of the claims comprised in them are Categories 1, 2 and 10; d. that certain claims would, or might, be incapable of being compromised by means of a scheme -- the category which is attributable (in whole or in part) to the inability to compromise obligations is Category 2; e. that certain claims would, unless excluded, form a separate class which it would be impractical to consult on that basis -- the categories which are attributable (in whole or in part) to impractical class problems are Categories 9 and 14; f. that there are certain claims which it would be uneconomic to include -- the categories which are attributable (in whole or in part) to the costs of including them are Categories 13 and 14; and g. claims that relate to parties who are assisting in the consideration, negotiation and/or implementation of the Corp Scheme -- the category which is attributable (in whole or in part) to the implementation of the Corp Scheme is Category 12. Further details of the specific reasons for each Category are set out below. CATEGORY 1 CLAIMS OF EMPLOYEES OF CORP (WHO WERE EMPLOYEES AT THE RECORD DATE) UNDER THEIR RESPECTIVE CONTRACTS OF EMPLOYMENT AND FEE ARRANGEMENTS OF DIRECTORS (WHO WERE DIRECTORS AT THE RECORD DATE) The success of the restructured Group relies heavily upon the commitment to the restructuring and to the restructured Group of the employees and directors who will remain with the Group. It would therefore be commercially impractical for these liabilities to be compromised. In addition, part of the employee claims may be preferential in the event of a liquidation of Corp. CATEGORY 2 CORP'S LIABILITY IN RESPECT OF ANY CORP PENSION PROMISES OR ARRANGEMENTS Any sum which is owed by Corp and which is a sum to which Schedule 4 to the Pension Schemes Act 1993 applies (contributions to occupational pension schemes and state scheme premiums) would be preferential on a winding up of Corp and therefore it would be inequitable to scheme these liabilities. 783

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- In addition, sections 91 and 92 of the Pensions Act 1995 provide that entitlements to a pension under an occupational pension scheme or rights to a future pension under such a scheme are generally inalienable and cannot be forfeited. It is considered that sections 91 and 92 would probably prevent the compromise or arrangement of certain pension liabilities by way of a scheme of arrangement. In addition it was thought that the right by the trustees under certain pension plans to collect any debt due to existing underfunding of these schemes could also not be schemed because of these provisions. In addition, those US pension plans where the US pensions government agency, the PBGC, may be in a position to take action against Corp will be excluded, together with any liabilities owed by Corp to the PBGC. As the liability will remain in the Group at the Affiliate level, it is thought impracticable to scheme these liabilities as it may accelerate claims or other action which would not otherwise be made or taken. Furthermore, the beneficiaries of a number of the pension schemes are continuing employment with Corp and accordingly it is considered commercially impracticable to scheme these liabilities. CATEGORY 3 CERTAIN GUARANTEE OR INDEMNITY OBLIGATIONS OF CORP GIVEN IN RESPECT OF OBLIGATIONS OF AFFILIATES WHICH ARE CONSIDERED TO BE BENEFICIAL TO THAT AFFILIATE'S ONGOING OPERATIONS It is fundamental to the ongoing operations and business of the Corp Group going forward that trading and financial relationships which are beneficial to members of the Corp Group are preserved. Corp has guarantee or indemnity obligations in respect of certain obligations of Affiliates which are considered to be beneficial to the relevant Affiliate. To scheme these liabilities of Corp may have the effect of precipitating action by the counterparty to that contract which could threaten the viability of that Affiliate as a business and therefore threaten the future of the Corp Group. Accordingly where a liability of Corp may have the effect of impacting on a relationship or contract which is beneficial to an Affiliate in this way, the liability will be excluded. CATEGORY 4 LIABILITIES IN RESPECT OF TRADING OBLIGATIONS OF CORP OR ITS AFFILIATES UNDER CONTRACTS WHERE, AND TO THE EXTENT THAT, CORP IS A JOINT OR JOINT AND SEVERAL OBLIGOR WITH ONE OR MORE AFFILIATES It is fundamental to the ongoing operations and business of the Corp Group going forward that the Trading Obligations under contacts where Corp is joint and severally liable with one or more of its Affiliates are not schemed, thereby precipitating action against Corp or the Affiliate which may impact the future of the Corp Group. CATEGORY 5 CONTRACTUAL OBLIGATIONS, INCLUDING WARRANTY AND INDEMNITY OBLIGATIONS, OF CORP UNDER DISPOSALS AND ACQUISITIONS (EACH OTHERWISE THAN IN THE ORDINARY COURSE OF BUSINESS) DEMERGERS, MERGERS AND JOINT VENTURES AND ANY PRE-DISPOSAL LIABILITIES There is a risk that including such claims may encourage or accelerate claims which would not otherwise be made as many of the liabilities under disposal contracts or Pre-Disposal Liabilities are presently contingent liabilities. In addition scheming such liabilities: a. would be inconsistent with the concept of the early First Initial Distribution and may have the effect of preventing closure of the Corp Scheme; and b. may detrimentally affect the success of the Corp Scheme as exposure to such claims would impact upon the ability to include in the Scheme an immediate distribution to Admitted Scheme Creditors and upon the ability to demonstrate the adequacy of the reserve. 784

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- CATEGORY 6 INTRA-GROUP LOAN AND TRADING ACCOUNT CLAIMS AGAINST CORP BY ANY AFFILIATE Given the complex matrix of intra-group lending and trading accounts (in which Corp is the treasury vehicle) including these liabilities in the Scheme would impact upon the ability of the Corp Group to operate and/or trade and in some cases may affect the solvency of the members of the Corp Group and its Affiliates. Accordingly these creditors will be excluded in order to maintain stability. In addition we refer you to the arrangements relating to the statement and waiver of intra-group claims described more fully in part I, Section 2, Part D.6. CATEGORY 7 CORP'S LIABILITIES UNDER COMMERCIAL CONTRACTS OR LICENCES RELATING TO THE WIDER CORP GROUP AND ONGOING TRADING OPERATIONS OF AFFILIATES TO WHICH CORP IS A PARTY AND WHICH ARE REGARDED AS BENEFICIAL TO THE WIDER CORP GROUP'S ONGOING OPERATIONS AND THE DOCUMENTATION WHICH HAS BEEN ENTERED INTO IN CONNECTION WITH THE RESTRUCTURING PRIOR TO THE RECORD DATE These liabilities are not being schemed as the contracts, the goods or services supplied thereunder and/or the ongoing relationship with the counterparty are considered to be important or beneficial to the ongoing operations of the Wider Corp Group. In addition a number of these contracts have been entered into in connection with the Restructuring and it is therefore necessary to exclude the liabilities created thereunder. CATEGORY 8 ORDINARY COURSE OF BUSINESS LIABILITIES INCURRED IN CONNECTION WITH THE SUPPLY OF GOODS AND/OR SERVICES TO CORP These liabilities are not being schemed as the goods and services supplied and/or the ongoing relationship with the counterparty is important or beneficial to the operations of the Wider Corp Group. CATEGORY 9 CORP'S LIABILITIES TO THIRD PARTIES WHICH ARE COVERED BY A CORP INSURANCE POLICY AND LIABILITIES OF CORP WHICH WOULD BE COVERED BY A CORP INSURANCE POLICY BUT FOR: A. ANY EXCESS, DEDUCTIBLE OR LIMIT OF LIABILITY APPLICABLE UNDER ANY CORP INSURANCE POLICY TO ANY SUCH LIABILITY; OR B. ANY INSURER FAILING TO SATISFY ANY CORP INSURANCE POLICY CLAIM IN FULL WHEN PAYABLE WHEN THE INSURER IS IN LIQUIDATION, PROVISIONAL LIQUIDATION OR ADMINISTRATION UNDER THE INSOLVENCY ACT 1986 (AS AMENDED FROM TIME TO TIME) OR SUBJECT TO ANY SCHEME OF ARRANGEMENT UNDER SECTION 425 OF THE ACT (OR ANY EQUIVALENT OR ANALOGOUS PROCEEDING OR ARRANGEMENT IN ANY OTHER JURISDICTION, INCLUDING ANY PROCEEDING UNDER CHAPTER 11 OF THE BANKRUPTCY CODE); OR C. THE CORP INSURANCE POLICY OR ANY CLAIM UNDER IT BEING VOID OR AVOIDED BY ANY INSURER, BEING LIABILITIES OF CORP IN RESPECT OF WHICH THE THIRD PARTY WOULD HAVE RIGHTS AGAINST THE INSURER UNDER THAT CORP INSURANCE POLICY BY VIRTUE OF SECTION 1 OF THE 1930 ACT IN THE EVENT THAT ANY OF THE EVENTS SET OUT IN SECTION 1(1)(B) OF THE 1930 ACT OCCURRED WITH RESPECT TO CORP These claims are covered by a third party insurer in circumstances where Corp's rights against the insurer in respect of its liability to the third party concerned would be transferred to and vest in the third party by virtue of the Third Party (Rights Against Insurers) Act 1930 (the "1930 Act") if Corp were to enter into a administration or insolvency proceeding. The 1930 Act has the effect of putting creditors in this category into an equivalent position to a creditor with security, and accordingly those creditors would constitute a separate class of creditor for the purposes of the Scheme if their insured claims were treated as Scheme Claims. 785

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- This category of Excluded Claims extends to claims that would be recoverable from an insurer but for the fact that the insurer concerned has entered into an insolvency proceeding under the Insolvency Act 1986 (or any equivalent proceeding under any foreign jurisdiction). Corp has a contingent liability for industrial injury and disease claims from former and current employees where its liability was insured with Chester Street Insurance Holdings Limited ("Chester Street") which was formerly known as Iron Trades Holdings Limited. Chester Street is insolvent and in provisional liquidation. Certain of these employers liability claims will be recoverable in full, notwithstanding Chester Street's insolvency, by virtue of compensation schemes operated by Financial Services Compensation Scheme Limited pursuant to the Financial Services and Markets Act 2000 or the Policyholders Protection Act 1975. Where that is the case, the claimant would have the right to payment under the appropriate compensation scheme by virtue of the 1930 Act if Corp were to enter into any insolvency proceeding. The potential application of the compensation schemes to certain third parties with claims insured by Corp with an insolvent insurer means that, unless treated as Excluded Creditors, such creditors might still be better off if Corp were to enter into insolvency or administration proceedings under the Insolvency Act 1986. It is not practicable to distinguish between those creditors in respect of which Corp's potential liability is covered under a contract of UK employers liability or motor liability who would benefit from a compensation scheme and those who are not. Corp does not regard it as practical to scheme any insurance policy deductible or excess applicable to a claim covered by insurance for the following reasons: a. the amounts involved are not expected to be material in the context of the Scheme; and b. it would be impossible to determine in advance who would be excluded and who would be schemed if the amounts over and above the deductibles and excesses were treated as Scheme Claims. In addition, Corp does not regard it as practicable to scheme any liability to a third party in an amount greater than the third party would have been able to recover from the insurer if the 1930 Act applied by reason of any applicable limit of liability within the policy. This is for the following reasons: a. the scheming of potential claims in respect of industrial injury, which could potentially arise a number of years from the Effective Date, may have the effect of preventing closure of the Corp Scheme; and b. scheming such liabilities may detrimentally affect the success of the Corp Scheme as exposure to such claims would impact upon the ability to include in the Scheme an immediate distribution to Admitted Scheme Creditors and upon the ability to demonstrate the adequacy of the reserve. CATEGORY 10 PREFERENTIAL CLAIMS These creditors are being excluded on the basis that, in a liquidation of Corp, they would rank in priority to the other creditors of plc. Accordingly these creditors would be likely to receive the full amount of their claim in a liquidation of Corp. To include them as Scheme Creditors would prejudice their rights. CATEGORY 11 RIGHTS OF INDEMNITY OF DIRECTORS AND OFFICERS OF CORP (WHO WERE DIRECTORS AND/OR OFFICERS AT THE RECORD DATE) AGAINST CORP UNDER ITS ARTICLES OF ASSOCIATION AND AT COMMON LAW The directors are assisting with the implementation of the Restructuring for the benefit of the creditors and stakeholders of the Marconi Group and it would be unfair for them to do so without the indemnity. 786

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- CATEGORY 12 COSTS, FEES AND EXPENSES OF THE RESTRUCTURING PARTIES AND ADVISERS (AND ANY LIABILITY UNDER ANY ENGAGEMENT LETTER OR SIMILAR ARRANGEMENT ENTERED INTO BY CORP WITH SUCH PARTIES) INCURRED IN CONNECTION WITH THE CONSIDERATION, NEGOTIATION AND IMPLEMENTATION OF THE RESTRUCTURING It is essential that parties that are working in connection with the proposed restructuring of Corp are paid in full in order to ensure their continued assistance in the process. CATEGORY 13 LIABILITIES OF CORP TO A CREDITOR WHERE ALL SUCH LIABILITIES IN AGGREGATE TO THAT CREDITOR DO NOT EXCEED L5,000 WHICH, FOR THE AVOIDANCE OF DOUBT, DO NOT INCLUDE ANY LIABILITIES IN RESPECT OF BONDS These liabilities are being excluded on the basis that their claims are de minimis and the costs of distributing the scheme document to such claimants, administering such claims under the Scheme and distributing the Scheme Consideration is disproportionate to the benefit derived from not paying such claims in full. CATEGORY 14 LIABILITIES IN RESPECT OF DIVIDENDS DECLARED PRIOR TO THE RECORD DATE ON THE SHARES IN THE CAPITAL OF CORP BUT NOT CLAIMED BY THE RELEVANT SHAREHOLDER OR FORMER SHAREHOLDER By reason of section 74(2)(f) of the Insolvency Act 1986 creditors in respect of unclaimed dividends would, if Corp were to be wound up, be subordinated; and that therefore they would be in a separate class from that of general unsecured creditors. As by reason of Article 136 of Corp's Articles of Association claims of this nature are not barred until the expiration of 12 years, there are tens of thousands of such creditors. It would be excessively expensive to identify them, to send the Scheme Document to each of them and, in the event that the recipients of the Scheme Document did make a claim, to administer their claim and distribute Scheme Consideration to them. As a practical matter it would be necessary to provide that the Scheme could take effect even if, at the separate class meeting of creditors in this category, the statutory majority (or a sufficiently representative turnout) were not obtained, and this would remove any incentive for the class to vote in favour of the Scheme. Given the fact that almost all claims would in any event be excluded under Category 13, the decision has been taken to exclude whatever other claims of this nature remain outstanding. CATEGORY 15 LIABILITIES IN RESPECT OF THE LEASE OF THE PROPERTY AT 329-333 HIGH STREET, STRATFORD, LONDON The property at 329-333 High Street, Stratford is considered to be an asset as opposed to a liability of Corp. CATEGORY 16 CORP'S LIABILITIES UNDER THE RESTRUCTURING UNDERTAKING AGREEMENTS OF EACH ESOP DERIVATIVE BANK, THE ESOP ESCROW AGREEMENT, MOBILE ESCROW AGREEMENT, SUBSEQUENTLY SOLD OPCO ESCROW AGREEMENTS AND THE ESOP SETTLEMENT AGREEMENT Details of the arrangements with the ESOP Derivative Banks are described in part I, Section 2, Part D.2. The settlement of the claims of the ESOP Derivative Banks has been negotiated on the basis that the claims of the ESOP Derivative Banks will be excluded from the Schemes. CATEGORY 17 CORP'S LIABILITY IN RESPECT OF ANY PERSONAL INJURY CLAIMS WHICH ARE NOT EXCLUDED FROM THE CORP SCHEME UNDER CATEGORY 9 ABOVE It is thought necessary to exclude such liabilities on the grounds that potential claimants under these categories may be unaware of their contingent right to claim as personal injury claims are often latent in nature. To include such creditors in the Scheme may give rise to unfairness issues. 787

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- Furthermore, in order to scheme such claims it would be necessary to ensure that sufficient Scheme Consideration is reserved for such creditors. Accurately estimating the provision necessary to adequately cover the potential claims is considered to be extremely difficult. In addition: a. scheming such claims may have the effect of preventing closure of the Corp Scheme; and b. scheming such liabilities may detrimentally affect the success of the Corp Scheme as exposure to such claims would impact upon the ability to include in the Scheme an immediate distribution to Admitted Scheme Creditors and upon the ability to demonstrate the adequacy of the reserve. CATEGORY 18 CORP'S LIABILITY (IF ANY) IN RESPECT OF THE ITALIAN IMPLIED GUARANTEE Article 2362 of the Italian Civil Code provides that, in the insolvency of an SpA, its sole shareholder (if it is 100 per cent. owned by one entity) is liable for all obligations incurred by that SpA during the period in which it was the sole shareholder. The sole shareholder is liable whether or not it is itself an Italian company. Between March 2000 and 29 October 2001, Corp was the direct holding company of the Italian group, by virtue of being the sole shareholder in Marconi Finanziaria SpA (now Marconi Holdings SpA) ("MHSpA"). MHSpA in turn was the 100 per cent. owner of the Italian operating companies, primarily Marconi Communications SpA and Marconi Mobile SpA ("Secure Comms"). MHSpA has since been demerged into MHSpA and Mobile. As a result of its 100 per cent. shareholding in MHSpA between March 2000 and 29 Oct 2001, should MHSpA become, or be declared, insolvent at any time, Corp would have implied guarantee obligations with respect to all debts/obligations incurred by MHSpA between March 2000 and 29 October 2001. MHSpA may in turn have an implied guarantee obligation in respect of Marconi Communications SpA and Secure Comms (for the period in which it was the 100 per cent. owner of those companies). The implied guarantee would normally be enforced by the trustee in bankruptcy if the SpA is formally declared insolvent; however, prior to formal declaration of insolvency, individual creditors would still have rights under Article 2362. As the liabilities are ones which may not arise, it is intended that any liability under the implied guarantee should be excluded; to include this claim may encourage or accelerate a claim which may not otherwise be made, which could have a detrimental effect on the ability to include in the Scheme an immediate distribution to Admitted Scheme Creditors and the ability to demonstrate the adequacy of the reserve. 788

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- PART IV -- EXPLANATION FOR EXCLUSIONS AT PLC LEVEL GENERAL There are limited exclusions for the plc Scheme. The claims of certain creditors have been excluded from the plc Scheme for a variety of reasons as follows: (a) contracts that will be novated to Corp or claims that will be settled -- the categories which are attributable (in whole or in part) to this are Categories 1 and 9; (b) claims that would be preferential if plc were to be wound up -- the categories which are attributable (in whole or part) to the preferential nature of the claims comprised in them are Categories 2 and 3; (c) claims that would, or might, be incapable of being compromised by means of a scheme -- the category which is in part attributable to this being incapable of compromise is Category 2; (d) claims that would, unless excluded, form a separate class which it would be impractical to consult on that basis -- the category which is attributable to impractical class problems is category 4; (e) claims which it would be uneconomic to include -- the category which is attributable to the cost of including them is Category 8; and (f) claims that relate to parties who are assisting in the consideration, negotiation and/or implementation of the plc Scheme -- the categories which are attributable (in whole or in part) to assisting in the implementation of the plc Scheme are Categories 5, 6, 7 and 9. CATEGORY 1 COMMERCIAL CONTRACTS THAT WILL BE NOVATED TO CORP ON OR BEFORE THE EFFECTIVE DATE plc's guarantee of the obligations of Marconi (Bruton Street) Limited under the sale and purchase agreement entered into in connection with the disposal of the entire issued capital of Marconi Mobile Holdings SpA to Finmeccanica SpA On 2 August 2002, Marconi (Bruton Street) Limited ("MBSL") disposed of the entire issued share capital of Marconi Mobile Holdings SpA (the holding company for the Marconi Mobile group in Italy) ("Mobile") to Finmeccanica SpA. As part of that disposal, plc guaranteed the obligations of MBSL under the sale and purchase agreement (the "Finmeccanica Guarantee"). The sale and purchase agreement also provided that if, as a result of a restructuring of the Marconi group, plc ceases to be the ultimate parent company of MBSL, plc is obliged to novate the Finmeccanica Guarantee to the ultimate holding company of the restructured group. Finmeccanica is obliged to execute that novation agreement and thereby release plc from its obligations under the Finmeccanica Guarantee. Under a side letter between Corp and plc, Corp agreed that if, as a result of such a restructuring, Corp became the ultimate holding company of MBSL, it would accept such a novation of the Finmeccanica Guarantee (or, if another entity became the ultimate holding company of MBSL, Corp would procure that such company would enter into a novation agreement). Corp agreed to this as it received a benefit from the sale of Mobile. The license granted by Lemelson Medical, Education and Research Foundation Limited dated 1 December 1999 Under an agreement dated 1 December 1999 between Lemelson Medical, Education and Research Foundation, Limited Partnership ("Lemelson") and plc ("Lemelson Agreement") Lemelson licenses certain patents to plc for the benefit of plc and relevant members of the Marconi Group. The royalty payments due under the Lemelson Agreement were paid by plc on behalf of the relevant members of the Group (and, in effect, charged back to such Group members). The Lemelson Agreement was entered into as a result of patent litigation commenced by Lemelson against plc. The Lemelson Agreement is of ongoing benefit to members of the Group but is of no direct benefit to plc. It is therefore appropriate for the Lemelson Agreement to be novated to Corp. 793

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- The agreements entered into between plc and BAE or entered into between Corp and BAE and subsequently novated from Corp to plc, in respect of the merger of the Group's defence business with BAE The separation of the Group's defence businesses ("MES") and subsequent merger with BAE was completed in November 1999. The original transactions agreement and payment deed which set out the principles of the merger were entered into between Corp and BAE. These agreements were subsequently novated from Corp to plc and plc also became the relevant Marconi party to all other agreements entered into at completion of the merger (the "BAE Merger Agreements"). As part of the transaction plc agreed to try and obtain the release of any MES companies from arrangements (including guarantees) which they had made for the benefit of the businesses retained by plc and further agreed to indemnify the relevant BAE company for any payment which arose under those arrangements should plc fail to obtain such a release. Equally BAE agreed to try and obtain the release of any Group companies from arrangements (including guarantees) made for the benefit of MES companies and also agreed to indemnify the relevant Group company against any payments which subsequently arose in the event that BAE failed to obtain such release. The BAE Merger Agreements would, in the normal course of events, be schemed and thus both BAE and the Group would lose the benefit of the indemnities going forward. Therefore, in order to ensure that these existing arrangements continue it is necessary to novate all of the BAE Merger Agreements to Corp. CATEGORY 2 PLC'S LIABILITIES IN RESPECT OF ANY PLC PENSION PROMISES OR ARRANGEMENTS Any sum which is owed by plc and is a sum to which Schedule 4 to the Pension Schemes Act 1993 applies (contributions to occupational pension schemes and state scheme premiums) would be preferential on a winding up of plc and therefore it would be inequitable to scheme these liabilities. In addition, sections 91 and 92 of the Pensions Act 1995 provide that entitlements to a pension under an occupational pension scheme or rights to a future pension under such a scheme are generally inalienable and cannot be forfeited. It is considered that sections 91 and 92 would probably prevent the compromise or arrangement of certain pension liabilities by way of a scheme of arrangement. In addition, it was thought that the right by the trustees under certain pension plans to collect any debt due to existing underfunding of these schemes could also not be schemed because of those provisions. Legal authority is unclear as to whether any Liability which plc might have under section 75 of the Pensions Act 1995 is safeguarded by sections 91 and/or 92 of that Act and accordingly specific wording has been included to clarify that liabilities under section 75 are excluded. In any event, plc does not consider that any Liability would arise under section 75 in respect of plc. Furthermore certain beneficiaries are continuing their employment with Corp and accordingly Corp will take on plc's liabilities post-Effective Date. CATEGORY 3 PREFERENTIAL CLAIMS These creditors are being excluded on the basis that, in a liquidation of plc, they would rank in priority to the other creditors of plc. Accordingly these creditors would be likely to receive the full amount of their claim in a liquidation of plc. To include them as Scheme Creditors would prejudice their rights. CATEGORY 4 LIABILITIES IN RESPECT OF DIVIDENDS DECLARED PRIOR TO THE RECORD DATE ON THE SHARES IN THE CAPITAL OF PLC BUT NOT CLAIMED BY THE RELEVANT SHAREHOLDER OR FORMER SHAREHOLDER In an insolvent liquidation of plc the claims of creditors in respect of unclaimed dividends would be subordinated to the claims of all other creditors. They are therefore in a different class from other creditors of plc. There are three ways in which these creditors could be treated: they could be included in the Scheme; they could be excluded from the Scheme and left unpaid on the ground that with their subordinated status they have no interest in plc's assets; or they could be excluded from the Scheme and paid if and when a claim is made. 794

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- The first way would involve a separate class meeting of these creditors. This has been rejected because it would be exceedingly expensive to identify them, to send the Scheme Document to each of them and, in the event that the recipients of the Scheme Document did make a claim, to administer their claim and distribute Scheme Consideration to them. As a practical matter it would be necessary, in order to be on the safe side, to provide that the Scheme could take effect even if, at the separate class meeting of creditors in this category, the statutory majority (or a sufficiently representative turnout) were not obtained, and this would remove any incentive for the class to vote in favour of the Scheme. The second way would leave them with unpaid claims against plc in the capacity as creditor and could therefore result in an insolvent liquidation of plc. This approach has been rejected because if this were to occur in the early stages of the implementation of the Schemes, it may have implications for the reputation of the Marconi name and accordingly may impact upon the trust of third parties to deal with members of the Corp Group going forward. In addition given the fact that almost all claims would in any event be excluded under Category 8, the decision was taken to exclude whatever other claims of this nature remain outstanding. Therefore it is proposed that they be excluded from the plc Scheme and paid in full if and when a claim is made. CATEGORY 5 COSTS, FEES AND EXPENSES OF THE RESTRUCTURING PARTIES AND ADVISERS (AND LIABILITY UNDER ANY ENGAGEMENT LETTER OR SIMILAR ARRANGEMENT ENTERED INTO BY PLC WITH SUCH PARTIES), INCURRED IN CONNECTION WITH THE CONSIDERATION, NEGOTIATION AND IMPLEMENTATION OF THE RESTRUCTURING AND COSTS, FEES AND EXPENSES OF ALL ADVISERS TO PLC IN CONNECTION WITH THE PLC ONGOING LITIGATION It is essential that parties that are working in connection with the plc Scheme are paid in full in order to ensure their continued assistance in the process. Furthermore parties are advising plc in connection with the defence of claims brought against plc and it would be unreasonable to expect the relevant parties to continue to offer their services after the Effective Date if any existing claims that they may have were to be schemed. CATEGORY 6 LIABILITIES OF PLC TO PARTIES WHICH WILL BE PROVIDING THE PLC SERVICES These liabilities are being excluded on the basis that the services of these parties are required following the Effective Date of the plc Scheme and it would be unreasonable to expect the relevant parties to continue to offer their services after the Effective Date if any existing claims that they may have were to be schemed. CATEGORY 7 FEE AND SERVICE ARRANGEMENTS OF DIRECTORS (WHO WERE DIRECTORS AT THE RECORD DATE) These liabilities are being excluded on the basis that the services of these parties are required following the Effective Date of the plc Scheme and it would be unreasonable to expect the relevant parties to continue to offer their services after the Effective Date if any existing claims that they may have were to be schemed. CATEGORY 8 LIABILITIES OF PLC TO A CREDITOR WHERE ALL SUCH LIABILITIES IN AGGREGATE OF THAT CREDITOR DO NOT EXCEED L5,000 WHICH, FOR THE AVOIDANCE OF DOUBT, DO NOT INCLUDE ANY LIABILITIES IN RESPECT OF BONDS These liabilities are being excluded on the basis that their claims are de minimus and the costs of distributing the Scheme Document to such claimants, administering their claims under the Scheme and distributing the Scheme Consideration would be disproportionate to the benefit derived from not paying such claims in full. 795

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 9: EXCLUDED CLAIMS -------------------------------------------------------------------------------- CATEGORY 9 LIABILITIES OF PLC UNDER: A. THE RESTRUCTURING UNDERTAKING AGREEMENTS OF EACH ESOP DERIVATIVE BANK, THE ESOP ESCROW AGREEMENT, MOBILE ESCROW AGREEMENT, SUBSEQUENTLY SOLD OPCO ESCROW AGREEMENTS, THE ESOP SETTLEMENT AGREEMENT AND THE PLC GUARANTEE OF THE ESOP DERIVATIVE TRANSACTIONS; AND B. THE DOCUMENTATION WHICH HAS BEEN ENTERED INTO IN CONNECTION WITH THE RESTRUCTURING PRIOR TO THE RECORD DATE Details of the equity derivative and settlement arrangements with the ESOP Derivative Banks are described in part I, Section 2, Part D.2. The settlement of the claims of the ESOP Derivative Banks referred to in that Part has been negotiated on the basis that the ESOP related claims of the ESOP Derivative Banks will be excluded from the plc Scheme. As plc is entering into a number of agreements in connection with the Restructuring, it is considered necessary to exclude those agreements. 796

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 10 SECURITY AND INTERCREDITOR ARRANGEMENTS The New Senior Notes, the New Junior Notes and the Performance Bonding Facility will benefit from guarantees ("GUARANTEES") to be provided by each of the Group Companies set out below ("GUARANTORS") with the exception of (1) Marconi Communications Telemulti Ltda, which is a Brazilian company that will neither provide a Guarantee nor provide any Security except the quotas (equity interests) which will be pledged as Security by its non-Brazilian parent company, both of which will be deemed to be Guarantors for the purposes of the covenants in the Indentures; and (2) Corp, which will not provide guarantees of the New Senior Notes or New Junior Notes because it is the issuer of those Notes. Except as described in Part 2 of this Appendix 10, each Guarantee will be supported by security over certain assets of the respective Guarantor ("SECURITY"). Those Group Companies marked with an * will constitute "US Guarantors" under the New Notes; all other Group Companies listed below will constitute "Non-US Guarantors" under the New Notes. US Guarantors comprise the Guarantors that are Ringfenced Entities, and Non-US Guarantors comprise all other Guarantors. All Security and Guarantees shall be provided subject to limitations imposed by applicable law or arising by reason of directors' fiduciary duties or other potential liabilities. The limitation language will be set out in the Security Trust and Intercreditor Deed. See "Risk Factors --Risks related to ownership of the New Shares, the New Notes and the Warrants -- The value of the guarantees and the collateral may be limited by applicable laws" in Section I, Part F.4. Subject to local law, the Security will be granted to the Security Trustee which will hold the Security on behalf of the trustees of the New Notes (on behalf of the holders of the New Notes), the banks providing the Performance Bonding Facility and certain other Secured Creditors. The ranking of the Guarantees and Security, as between the New Senior Notes, the New Junior Notes and the Performance Bonding Facility is set out in the Security Trust and Intercreditor Deed, and a summary of it is detailed below. 1. GUARANTORS AS AT THE ISSUE DATE Capitalised terms in this Section "Guarantors as at the Issue Date" have the meaning given to them in Appendix 8: Terms of the New Senior Notes and New Junior Notes.

The Intellectual Property arrangements to be entered into by Guarantors incorporated in England is set out in Part 1, Section 2, part A.5; b. each Guarantor incorporated in the United States will grant a security interest in the shares it owns in Guarantors (including the shares of subsidiaries of the Guarantors where significant) by way of a share pledge agreement. In addition, each such Guarantor will grant a security interest in its key real property by way of a mortgage and in its personal property (including certain significant intercompany loans) by way of a security agreement. The security agreement will also cover each US Guarantor's intellectual property, including without limitation the Patents that it will subsequently assign to Ringfenced IPR Co. or US IPR Co., any future-acquired or future-developed Intellectual Property and any rights it may have or acquire as licensee or licensor. Immediately after the grant of the security each such Guarantor (other than Ringfenced IPR Co. or US IPR Co.) will assign the Patents it owns to either Ringfenced IPR Co. or US IPR Co., as applicable; c. each Guarantor incorporated in Germany, Italy and any subsequently added civil law jurisdictions will provide fixed security over certain material assets, in particular receivables, certain significant intercompany loans, bank accounts, moveable assets and the shares of the Guarantors (including the shares of subsidiaries of the Guarantors where significant) as a floating charge is not available in civil law jurisdictions. No Guarantors incorporated in any civil law jurisdiction will provide security over intellectual property except those Guarantors which own Intellectual Property and which are incorporated in Germany and they shall provide security as described in part 1, Section 2, Part A.5; d. each Guarantor incorporated in the Netherlands, Switzerland, Mexico and Guernsey will provide security limited to a pledge over its shares granted by its parent companies and a pledge over its shares in Guarantors; and e. each Guarantor incorporated in Brazil will neither provide a Guarantee nor provide any security but the quotas (equity interests) in such Guarantor will be pledged as security by its non-Brazilian parent company, and such Guarantor will be deemed to be a Guarantor for the purposes of the covenants in the Indentures. 800

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 10: SECURITY AND INTERCREDITOR ARRANGEMENTS -------------------------------------------------------------------------------- 3. INTELLECTUAL PROPERTY The Intellectual Property arrangements are set out in detail in part 1, Section 2, Part A.5. 4. INTERCREDITOR ARRANGEMENTS Capitalised terms set out in this Section "Intercreditor arrangements" will have the meanings given to them below. 4.1 THE SECURITY TRUST AND INTERCREDITOR DEED DESCRIPTION OF THE SECURITY TRUST AND INTERCREDITOR DEED The intercreditor arrangements in respect of certain creditors of Marconi Corporation plc and the other Obligors under the Notes and the other Secured Liabilities are contained in the Security Trust and Intercreditor Deed, which binds each of the Secured Creditors, each of the Obligors and each of the Intra-Group Parties (each as defined below). The rights of the Secured Creditors are subject to the Security Trust and Intercreditor Deed pursuant to which the exercise by the Secured Creditors of their rights under the Security Documents may in certain circumstances be directed by, and is in most circumstances subject to the prior consent of, other parties to the Security Trust and Intercreditor Deed. The purpose of the Security Trust and Intercreditor Deed is to regulate, inter alia: (1) the ranking of claims of the Secured Creditors; (2) the exercise, acceleration and enforcement of rights by the Secured Creditors; (3) the rights of Secured Creditors to instruct the Security Trustee; (4) the rights of the Senior Note Trustee to issue a Standstill Notice; (5) the rights of the Secured Creditors during a Standstill Period and the effects of a Standstill Period; (6) the giving of consents and waivers and the making of modifications to the Relevant Documents; and (7) the rights of the Secured Creditors and the priorities following a Payment Stop Event. The Security Trust and Intercreditor Deed sets out the priority of payment of the claims of the Secured Creditors and provides for the subordination of certain intercompany claims by the Issuer and those of its Subsidiaries that are parties to the Security Trust and Intercreditor Deed. RANKING OF SECURED OBLIGATIONS AND PRIORITIES Each of the parties to the Security Trust and Intercreditor Deed will agree that the Secured Obligations owed by, and the Transaction Security granted by, the Obligors to the Secured Creditors and the Intra-Group Liabilities are subject to the payment priorities set out in the Security Trust and Intercreditor Deed and described below. PAYMENT PRIORITIES PRIOR TO A PAYMENT STOP EVENT Pursuant to the Security Trust and Intercreditor Deed, unless the Senior Note Trustee has notified the other Secured Creditors in writing that a Payment Stop Event has occurred and is continuing, all monies credited to the Existing Performance Bond Escrow Account shall continue to be applied in accordance with the terms of the Escrow Agreement, and all monies credited to the Mandatory Redemption Escrow Account shall be applied in accordance with the following priorities: a. first, to the Junior Note Trustee, to be applied to the satisfaction of liabilities to the holders of the Junior Notes; b. second, to the Senior Note Trustee to be applied to the satisfaction of liabilities to the holders of the Senior Notes; c. third, to any other person (other than the Issuer) so entitled to the proceeds; and d. fourth, to the Issuer. Upon the occurrence of a payment event of default under the New Bonding Facility Agreement and at any time thereafter while the same is continuing, but prior to the New Bonding Facility Agent being notified by the Senior 801

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 10: SECURITY AND INTERCREDITOR ARRANGEMENTS -------------------------------------------------------------------------------- Note Trustee of the occurrence of a Payment Stop Event, the New Bonding Facility Agent shall (on its own behalf and on behalf of the New Bonding Facility Banks) be entitled to demand from the obligors under the New Bonding Facility Agreement an amount sufficient to ensure that the Secured Obligations arising under the New Bonding Facility Agreement are fully cash-collateralised. PAYMENT PRIORITIES FOLLOWING A PAYMENT STOP EVENT Upon being notified in writing of the occurrence of a Payment Stop Event (which notice shall, in accordance with the provisions of the section captioned "Standstill Notice", be contained in the Standstill Notice required to be delivered to the Security Trustee), the Security Trustee will promptly instruct the Escrow Bank (1) to act in accordance with paragraph a. of the section captioned "Standstill Period and Payment from Escrow Accounts"; and (2) following the date of such notification and while the Payment Stop Event is continuing and after giving effect to any payment required by paragraph a. of the section captioned "Standstill Period and Payments from Escrow Accounts" to pay all monies credited to the Mandatory Redemption Escrow Account to the Security Trustee for it to apply such moneys, together with the proceeds of all recoveries received by the Security Trustee pursuant to any Enforcement Action, in accordance with the following payment priorities: a. first, to the fees and expenses of the Security Trustee, the Note Trustees and other agents; b. second, to the New Bonding Facility Agent, to be applied to the satisfaction of liabilities to the New Bonding Facility Banks under the New Bonding Facility Agreement; c. third, to the Senior Note Trustee, to be applied to the satisfaction of all liabilities to the holders of the Senior Notes; d. fourth, to the Junior Note Trustee, to be applied to the satisfaction of all liabilities to the holders of the Junior Notes; e. fifth, to any other person (other than the Issuer) so entitled to the proceeds; and f. sixth, to the Issuer, provided that such payments will only be made out of the Mandatory Redemption Escrow Account if the balance in such account is equal to or greater than L2.5 million. For the avoidance of doubt, when a Payment Stop Event ceases to be continuing, and provided that no Standstill Period is in effect, monies credited to the Mandatory Redemption Escrow Account shall thereafter be applied in accordance with the payment priorities specified above in this section with the caption "Payment Priorities Prior to a Payment Stop Event". UNDERTAKINGS Undertakings of Secured Creditors Each Secured Creditor will undertake and the Issuer will acknowledge that the Secured Creditors will not, except to the extent expressly permitted by the Security Trust and Intercreditor Deed: a. permit or require the Issuer or any other Obligor to discharge any of the Secured Obligations owed to it or any person which it represents; b. permit or require the Issuer or any other Obligor to pay, prepay, repay, redeem, purchase or voluntarily terminate or otherwise acquire any of the Secured Obligations owed to such Secured Creditor or any person which it represents; c. other than pursuant to the terms of the Relevant Documents, take, accept or receive the benefit of any Security (other than the Transaction Security) in respect of any of the Secured Obligations owed to it or any person which it represents; d. take or receive from the Issuer or any other Obligor by cash receipt, set off, any right of combination of accounts or in any other manner whatsoever, the whole or any part of the Secured Obligations owed to it or any person which it represents; 802

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 10: SECURITY AND INTERCREDITOR ARRANGEMENTS -------------------------------------------------------------------------------- e. agree to any amendment of the Relevant Documents to which it is a party; or f. take or omit to take any other action in relation to the Relevant Documents, the Secured Obligations or the Transaction Security whereby any ranking and/or subordination contemplated by the Security Trust and Intercreditor Deed may be impaired. Undertakings of the Obligors Each Obligor will undertake that it will not, except to the extent expressly permitted or required by the Security Trust and Intercreditor Deed: a. discharge any of the Secured Obligations; b. pay, prepay, repay, redeem, purchase, voluntarily terminate or otherwise acquire any of the Secured Obligations; c. other than pursuant to the terms of the Relevant Documents, create or permit to subsist any Security (other than the Transaction Security) for, or in respect of, any of the Secured Obligations; d. discharge the whole or any part of any of the Secured Obligations by cash payment, set-off, any right of combination of accounts or in any other manner whatsoever; e. agree to any amendment of the Relevant Documents to which it is a party; or f. take or omit to take any other action in relation to the Relevant Documents, the Secured Obligations or the Transaction Security whereby any ranking and/or subordination contemplated by the Security Trust and Intercreditor Deed may be impaired. Undertakings of the Intra-Group Borrowers Each Intra-Group Borrower will undertake that it will not, and the Intra-Group Creditors and the Issuer will acknowledge that the Intra-Group Borrowers which owe Intra-Group Liabilities to them will not, except as expressly permitted or required by the Security Trust and Intercreditor Deed or with the prior written consent of the Security Trustee (acting upon instructions of the Instructing Trustee): a. pay, prepay, repay, redeem, make any distribution in respect of, purchase or acquire any Intra-Group Liabilities in cash or in kind or apply any money or property in or towards discharge of any Intra-Group Liabilities; b. discharge any Intra-Group Liabilities by set-off, cash payment, any right of combination of accounts or in any other manner whatsoever; c. create or permit to subsist any Security for, or in respect of, any Intra-Group Liabilities unless permitted or required to do so pursuant to the terms of the Indentures; or d. take or omit to take any other action in relation to the Intra-Group Liabilities, the Relevant Documents, the Secured Obligations or the Transaction Security whereby the ranking and/or subordination contemplated by the Security Trust and Intercreditor Deed may be impaired. Undertakings of the Intra-Group Creditors Each Intra-Group Creditor will undertake that it will not, and the Issuer and Intra-Group Borrowers which owe Intra-Group Liabilities to them will acknowledge that the Intra-Group Creditors will not, except as expressly permitted or required by the Security Trust and Intercreditor Deed or with the prior written consent of the Security Trustee (acting on the instructions of the Instructing Trustee): a. demand or receive payment, prepayment, repayment, redemption or any distribution in respect of any Intra-Group Liabilities owed to it in cash or in kind or apply any money or property in or towards discharge of any such Intra-Group Liabilities; 803

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 10: SECURITY AND INTERCREDITOR ARRANGEMENTS -------------------------------------------------------------------------------- b. exercise any right of combination of accounts or set-off against the whole or any part of Intra-Group Liabilities owed to it; c. take, accept or permit to subsist or receive the benefit of any Security for, or in respect of, any Intra-Group Liabilities owed to it unless permitted or required to do so pursuant to the terms of the Indentures or the Security Trust and Intercreditor Deed; or d. take or omit to take any other action in relation to the Intra-Group Liabilities, the Secured Obligations or the Transaction Security whereby the ranking and/or subordination contemplated by the Security Trust and Intercreditor Deed may be impaired. PREPAYMENT, REDEMPTION AND GRANT OF SECURITY FOR NOTES Each of the parties to the Security Trust and Intercreditor Deed will agree and acknowledge that: a. the Obligors may pay, prepay, repay, redeem or purchase the Secured Obligations (i) under the Senior Notes and/or the Senior Note Indenture on each relevant Payment Date in accordance with the terms thereof and of the Security Trust and Intercreditor Deed and (ii) under the New Bonding Facility Agreement (including payments or repayments by way of cash collateralization or the provision of letters of credit, guarantees or similar instruments) on each relevant Payment Date in accordance with the terms thereof and of the Security Trust and Intercreditor Deed; b. the Obligors may pay, prepay, repay, redeem or purchase the Secured Obligations under the Junior Notes and/or the Junior Note Indenture provided such payments constitute Permitted Payments and are made in accordance with the terms of the Junior Notes, the Junior Note Indenture and the Security Trust and Intercreditor Deed; and c. the Note Trustees, as trustees for the holders of the relevant Notes, and the New Bonding Facility Agent, as trustee for the New Bonding Facility Banks, may, with the Security Trustee's prior written consent (not to be unreasonably withheld or delayed), take, accept or receive the benefit of any Security in addition to the Transaction Security only if the same Security is at the same time granted to and held by the Security Trustee as trustee for the Secured Creditors under the terms of the Security Trust and Intercreditor Deed. The Intra-Group Creditors will acknowledge and agree that any rights they may have against the Intra-Group Borrowers in relation to Intra-Group Liabilities are subordinated to the rights of the Secured Creditors against the Obligors and the Intra-Group Borrowers in accordance with the terms of the Security Trust and Intercreditor Deed. PERMITTED PAYMENTS a. Unless a Payment Stop Event is continuing or a Standstill Period is in effect, the Obligors may make Permitted Payments to the Secured Creditors on the relevant Payment Dates under the Relevant Documents and may, in respect of the Junior Notes, issue Junior PIK Notes to the holders of the Junior Notes on the relevant Payment Dates under the Junior Note Indenture. Notwithstanding the foregoing or any other provision of the Security Trust and Intercreditor Deed, the New Bonding Facility Agent, the New Bonding Facility Banks and the Senior Note Trustee may at all times receive payments on the applicable Payment Dates. These provisions will not prevent (i) the payment of amounts in the Mandatory Redemption Escrow Account otherwise in accordance with the Security Trust and Intercreditor Deed or (ii) the issue of Junior PIK Notes in the event of a Payment Stop Event or a Standstill Period. b. The Intra-Group Borrowers may make, and the Intra-Group Creditors may accept, any Permitted Payments in respect of Intra-Group Documents or, as the case may be, Intra-Group Liabilities provided that following the occurrence of an Event of Default which is continuing under the Senior Notes, the Senior Note Indenture, the Junior Notes or the Junior Note Indenture, unless otherwise requested by the Security Trustee in accordance with the Section captioned "Intra-Group Creditors: No Enforcement Action" the Intra-Group Borrowers which are also Guarantors shall only be permitted to make, and the Intra-Group Creditors shall only be permitted to accept, such payments to the extent they are made in order to fund the working capital or cash management requirements of the Group in the ordinary course of business; and, 804

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 10: SECURITY AND INTERCREDITOR ARRANGEMENTS -------------------------------------------------------------------------------- unless requested by the Security Trustee in accordance with the Security Trust and Intercreditor Deed such Permitted Payments shall in any event not be permitted to be made following (i) the occurrence of an Insolvency Event in relation to the Intra-Group Creditor making the relevant loan, or (ii) after the taking of any Action or Enforcement Action by any Secured Creditor. STANDSTILL NOTICE If the Senior Note Trustee becomes aware that a Standstill Event has occurred, it shall deliver to the Security Trustee (with a copy to the Issuer and the other Debt Representatives) a Standstill Notice and promptly on receipt of such notice the Security Trustee shall notify the other Secured Creditors of such Standstill Event. A Standstill Period shall commence on the date of the issuance of the Standstill Notice by the Senior Note Trustee, and shall end on the earlier of the dates specified in the definition of "Standstill Period" below. If the relevant Standstill Event is a Payment Stop Event the Standstill Notice delivered to Security Trustee shall state that to be the case. No Default with respect to the Senior Notes that existed or was continuing on the date a Standstill Notice was issued shall be, or be made, the basis of the issuance or an instruction for the issuance of another Standstill Notice unless such Default shall have been cured or waived for a period of not less than 90 consecutive days. STANDSTILL PERIOD AND PAYMENTS FROM ESCROW ACCOUNTS Promptly upon receipt of a Standstill Notice by the Security Trustee and the commencement of a Standstill Period, the Security Trustee will instruct the Escrow Bank: a. on the date of such notification and provided that on the preceding day no Standstill Period was in effect, to pay all monies credited to the Mandatory Redemption Escrow Account to the Security Trustee to be applied in accordance with the payment priorities set forth under the caption "Payment Priorities Prior to a Payment Stop Event" above; and b. following such date and while a Standstill Period is continuing, to hold any amounts credited to the Mandatory Redemption Escrow Account in such account and not apply such amounts until the earlier of cessation of such Standstill Period (in accordance with the definition thereof) and the occurrence of a Payment Stop Event. Following the cessation of the Standstill Period: a. provided no Payment Stop Event is continuing and no other Standstill Period is in effect, monies standing to the credit of the Mandatory Redemption Escrow Account shall be applied in accordance with the payment priorities set forth under the caption "Payment Priorities Prior to a Payment Stop Event" above; or b. if a Payment Stop Event is continuing, monies standing to the credit of the Mandatory Redemption Escrow Account shall be applied in accordance with the payment priorities set forth under the caption "Payment Priorities Following a Payment Stop Event" above. EFFECT OF PAYMENT STOP EVENT AND STANDSTILL PERIOD Whilst a Payment Stop Event is continuing or a Standstill Period is in effect, the Issuer shall not make and the Junior Note Trustee shall not accept any payments in respect of the Junior Notes (other than, to the extent permitted by the Security Trust and Intercreditor Deed, payments out of the Escrow Accounts in accordance with the priorities set out in the Security Trust and Intercreditor Deed), provided that the Issuer shall not be prohibited from issuing and the Junior Note Trustee and the holders of the Junior Notes shall be entitled to receive Junior PIK Notes.

(iii) Other Events: If the Company determines that an adjustment should be made to the Subscription Price and/or the Specified Number as a result of one or more events or circumstances not referred to in Conditions 5(A)(i) and (ii), the Company shall, at its own expense and acting reasonably, have Independently Determined as soon as practicable what adjustment (if any) to the Subscription Price and/or the Specified Number is fair and reasonable to take account thereof and the date on which such adjustment should take effect and upon such determination such adjustment (if any) shall be made and shall take effect in accordance with such determination. No such adjustment will be made where the effect would be to vary the Subscription Price by less than one per cent. (iv) General 825

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 12: CONDITIONS OF THE WARRANTS -------------------------------------------------------------------------------- (a) On any adjustment to the Subscription Price pursuant to this Condition 5(A), the resultant Subscription Price, if not an integral multiple of one penny, shall be rounded to the nearest whole penny (0.5 pence being rounded upwards). No adjustment shall be made to the Subscription Price where such adjustment (rounded if applicable) would be less than one per cent. of the Subscription Price then in effect. Any adjustment not required to be made, and any amount by which the Subscription Price has been rounded, shall be carried forward and taken into account in any subsequent adjustment but such subsequent adjustment shall be made on the basis that the adjustment not required to be made had been made at the prior relevant time. Notice of any adjustments to the Subscription Price or the Specified Number shall be given to the Warrant Holders in accordance with Condition 12 as soon as practicable after the determination thereof. (b) No adjustment will be made to the Subscription Price or the Specified Number where Shares or other securities (including rights, warrants or options) are issued, offered, exercised, allotted, appropriated, modified or granted to employees (including directors holding executive office) of the Company or any Subsidiary or any associated company of the Company pursuant to any employees' share scheme (as defined in Section 743 of the Act or any modification or re-enactment thereof). (c) The Subscription Price may not be reduced and the Specified Number may not be adjusted so that, on exercise of the Warrants, Shares would be issued at a discount to their nominal value. (d) Where more than one event which gives or may give rise to an adjustment to the Subscription Price or the Specified Number occurs within such a short period of time that it is Independently Determined that a modification to the operation of the adjustment provisions is required in order to give the intended result, such modification shall be made to the operation of the adjustment provisions as may be advised by such investment bank to be in its opinion appropriate to give such intended result. (e) Where the circumstances giving rise to any adjustment pursuant to this Condition 5(A) have already resulted or will result in an adjustment to the Subscription Price and/or the Specified Number or where the circumstances giving rise to any adjustment arise by virtue of any other circumstances which have already given or will give rise to an adjustment to the Subscription Price and/or the Specified Number, such modification shall be made to the operation of the provisions of this Condition 5(A) as may be Independently Determined to be appropriate to give the intended result. (f) If any doubt shall arise as to the appropriate adjustment to the Subscription Price and/or the Specified Number a certificate providing the Independently Determined adjustment shall be conclusive and binding on all concerned, save in the case of manifest or proven error. (g) If the Exercise Date in relation to any Warrant shall be after the record date for any such issue as is mentioned in Condition 5(A)(ii), but before the adjustment becomes effective under this Condition 5(A) (such adjustment a RETROACTIVE ADJUSTMENT), the Company shall (conditional upon the Retroactive Adjustment becoming effective) procure that there shall be allotted to the relevant Warrant Holder, in accordance with the provisions of Condition 3, such number of additional Shares as, together with the Shares allotted or to be allotted to the relevant Warrant Holder on exercise of the relevant Warrant, is equal to the number of Shares which would have been required to be allotted on exercise of such Warrant if the relevant adjustment to the Specified Number (reflecting the event referred to in Condition 5(A)(ii)) had in fact been made and became effective immediately after the relevant record date. (h) References to any issue or offer to Shareholders AS A CLASS BY WAY OF RIGHTS shall be taken to be references to an issue or offer to all or substantially all Shareholders by way of rights other than Shareholders to whom, by reason of the laws of any territory or requirements of any recognised regulatory body or any other stock exchange in any territory or in connection with fractional entitlements, or any other disapplication right of the Directors of the Company granted in the Articles, it is determined not to make such issue or offer. 826

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 12: CONDITIONS OF THE WARRANTS -------------------------------------------------------------------------------- (vi) Fractions of Shares No exercise of Warrants shall result in the issue of a fraction of a Share (including, for the avoidance of doubt, by virtue of a Retroactive Adjustment). If a Warrant Holder exercising his Warrants would, but for the preceding sentence and after aggregating all Warrants being exercised by him, be entitled to receive a number of Shares which includes a fraction of Shares, such Warrant Holder's entitlement to receive such number shall be rounded down to the nearest integral number of Shares to exclude fractions, whereupon he shall be paid the amount (in sterling) equal to the value of the fraction of Share forgone, as determined by the Company. Such payment shall be made, in each case subject to any applicable exchange control or other laws or regulations, (A) in the case of a Warrant held in uncertificated form, to the relevant Warrant Holder's cash memorandum account with the Operator in accordance with the rules of the Operator or (B) in the case of a Warrant held in certificated form, by cheque by ordinary uninsured mail to the exercising Warrant Holder (in accordance with the instructions contained in the Warrant Exercise Notice but at the risk of the exercising Warrant Holder).

DEALING DAY means a day on which the Relevant Stock Exchange is open for business and Shares may be dealt in on the Relevant Stock Exchange. DIVIDEND means any dividend or distribution, whether of cash, assets or other property, and whenever paid or made and however described (and for these purposes a distribution of assets includes without limitation an issue of shares or other securities credited as fully or partly paid up (other than an issue of Shares falling within Condition 5(A)(ii) by way of capitalisation of profits or reserves)). EQUITY SHARE CAPITAL has the meaning ascribed to it in Section 744 of the Act. 827

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 12: CONDITIONS OF THE WARRANTS -------------------------------------------------------------------------------- FAIR MARKET VALUE means, with respect to any property on any date, the Independently Determined fair market value of that property provided that (1) the fair market value of a cash Dividend paid or to be paid shall be the amount of such cash Dividend, (2) where options, warrants or other rights are publicly traded in a market of adequate liquidity, as Independently Determined, the fair market value of such options, warrants or other rights shall equal the arithmetic mean of the daily closing prices of such options, warrants or other rights during the period of five trading days on the relevant market commencing on the first such trading day such options, warrants or other rights are publicly traded, or such shorter period as such options, warrants or other rights are publicly traded, (3) where options, warrants or other rights are not publicly traded (as aforesaid), the fair market value of such options, warrants or other rights will be as Independently Determined on the basis of a commonly accepted market valuation method and taking account of such factors as are Independently Determined to be appropriate, including the market price per Share, the dividend yield of a Share, the volatility of such market price, prevailing interest rates and the terms of such options, warrants or other rights, including as to the expiry date and exercise price (if any) thereof, and (4) in the case of (1), converted into sterling (if declared or paid in a currency other than sterling) at the rate of exchange used to determine the amount payable to Shareholders who were paid or are to be paid the cash Dividend in sterling; and in the absence of such a stated rate of exchange and in the case of (2) and (3), converted into sterling (if expressed in a currency other than sterling) at such rate of exchange Independently Determined to be the spot rate at the close of business on that date (or if no such rate is available on that date the equivalent rate on the immediately preceding date on which such a rate is available). OFFICIAL LIST means the official list of the United Kingdom Listing Authority for the purposes of Part VI of the Financial Services and Markets Act 2000. RELEVANT STOCK EXCHANGE means at any time, in respect of the Shares, the Official List and/or, as the context requires, the market for listed securities of the London Stock Exchange or, if the Shares are not at that time so listed, the principal stock exchange or securities market on which the Shares are then listed or quoted or dealt in. SECURITIES includes, without limitation, shares in the share capital of the Company. (C) If an effective resolution is passed during the Subscription Period for the voluntary winding up of the Company then: (i) if such winding up be for the purpose of a reconstruction or amalgamation pursuant to a scheme or arrangement to which the Warrant Holders have consented by means of a Extraordinary Resolution, the terms of such scheme or arrangement shall be binding on all the Warrant Holders; and (ii) in any other case, the Company shall forthwith publish a notice in accordance with the provisions of Condition 12, stating that such a resolution has been passed and the Warrant Holder shall be entitled at any time within three months after the date such notice is published to elect by notice in writing to the specified office of the Registrar to be treated as if he had, immediately before the date of the passing of the winding up resolution, exercised his Warrants and he shall be entitled to receive out of the assets which would otherwise be available in the liquidation to the holders of Shares, such a sum (if any) as he would have received had he been the holder of and paid for the Shares to which he would have become entitled by virtue of such exercise, after deducting from such sum an amount equal to the moneys which would have been payable by him in respect of such Shares if he had exercised his Warrants but nothing contained in this sub-paragraph shall have the effect of requiring the Warrant Holder to make any actual payment to the Company. 6. The provisions for convening meetings of Warrant Holders to consider any matter affecting their interests, including the modification by Extraordinary Resolution of the Conditions, shall be as set out in Schedule 4 to the Deed Poll. An Extraordinary Resolution duly passed in accordance with the provisions of Schedule 4 to the Deed Poll at any meeting of the Warrant Holders shall be binding on all Warrant Holders, whether present or not. 828

Should any Warrant Certificate be mutilated, defaced, lost, stolen or destroyed it may be replaced at the Specified Office upon payment by the claimant of such costs incurred in connection therewith and on such terms as to evidence and indemnity as the Registrar and the Company may reasonably require. Mutilated or defaced Warrant Certificates must be surrendered before replacements will be issued. 8. Title to a Warrant in certificated form shall be transferable in any usual or common form or in any other form which may be approved by the Directors in units or multiples of one Warrant (provided that title to the Warrants comprised in a Warrant Certificate shall pass only on registration in the Register). The Company may deem and treat the Warrant Holder in certificated form as the absolute owner thereof for all purposes and shall not be affected by any notice to the contrary (except as ordered by a court of competent jurisdiction or required by law) and shall not (except as aforesaid) be bound to recognise any equitable or other claim to an interest in such Warrant. Transfers of Warrants in certificated form may be effected by delivery of the Warrant Certificate to the Specified Office with a completed form of transfer executed by the Warrant Holder without charge, but upon (i) payment of any taxes, duties and other governmental charges, (ii) the Registrar being satisfied with the evidence of title and identity of the person requesting transfer and of due execution of the transfer and subject to such reasonable regulations as the Registrar and the Company may prescribe. The Registrar will, within five London Business Days of such delivery, deliver at its Specified Office to the transferee or (subject to any applicable laws and regulations) despatch by mail (at the risk of the transferee) to such address as the transferee may request, a new Warrant Certificate in respect of the Warrant transferred. In the case of transfer of some only of the Warrants represented by the Warrant Certificate, a new Warrant Certificate in respect of the balance of the Warrants will be so delivered or despatched without charge to the transferor.

Warrants held in uncertificated form may be transferred in accordance with the CREST Regulations. No Warrant, either in certificated or uncertificated form, shall be transferable or exercisable until the Effective Date. If the Effective Date does not occur on or prior to the date falling thirty calendar days after the issue of the Warrants, the Warrants automatically become void. 9. The Company has the right to terminate the appointment of the Registrar provided that it will at all times maintain a Registrar with a specified office in England. Not less than 30 days' notice of any such termination or appointment shall be given by the Company to the Warrant Holders in accordance with Condition 12. 10. The Company will pay any United Kingdom stamp, issue, registration or similar taxes and any capital duties imposed on the Company in the United Kingdom (i) in connection with the issue of Shares on exercise of the Subscription Rights, except where the Shares are issued to a person whose business is, or includes, issuing depositary receipts, or a nominee of or agent for such a person, or a person whose business is, or includes, the provision of clearance services for the purchase or sale of chargeable securities, or a nominee of or agent for such a person, or (ii) payable upon the Deed Poll being produced in evidence in any proceedings in connection with the enforcement of the Deed Poll, the Warrants or the Subscription Rights. For the avoidance of doubt, other than United Kingdom taxes and duties imposed on the Company, the Company is not responsible for the payment of any taxes, duties and other governmental charges as may be payable in relation to the transfer of a Warrant. 829

By a resolution of Corp passed on 26 March 2003 it was resolved that: a. for the purpose of giving effect to the Corp Scheme and forthwith and conditionally upon the Court making an order sanctioning the Corp Scheme: (i) the Corp Directors be generally and unconditionally authorised, in accordance with section 80 of the Act, to exercise all powers of Corp to allot relevant securities (as defined for the purposes of that section) up to a maximum nominal amount of L69,100,000; (ii) the authority referred to in sub-paragraph (i) above shall expire on the day five years after the passing of the resolution; (iii) Corp may, before the authority referred to in sub-paragraph (i) above expires, make an offer or agreement which would or might require relevant securities to be allotted after it expires; (iv) all previous authorities under section 80 of the Act shall cease to have effect; (v) the Corp Directors be given power to allot for cash equity securities (as defined for the purposes of section 89 of the Act) pursuant to the general authority referred to in sub-paragraph (i) above as if section 89(1) of that Act does not apply to any such allotment, but that power, which expires on the day five years after the passing of the resolution, will be limited to: (A) the allotment of equity securities pursuant to the terms of the Corp Scheme; (B) the allotment of equity securities in connection with an offer or issue to or in favour of ordinary shareholders on the register on a date fixed by the Corp Directors where the equity securities respectively attributable to the interests of all those shareholders are proportionate (as nearly as practicable) to the respective number of ordinary shares held by them on that date but the Corp Directors may make such exclusions or other arrangements as they consider expedient in relation to fractional entitlements, shares represented by depositary receipts, legal or practical problems under the laws in any territory or the requirements of any relevant regulatory body or stock exchange; and 832

Section 89 of the Act confers on shareholders certain rights of pre-emption in respect of the allotment of equity securities which are, or are to be, paid up in cash other than by way of allotment to employees under an employee's share scheme as defined in section 743 of the Act. Following Listing of the New Shares, Corp will be subject to the continuing obligations of the UKLA with regard to the issue of securities for cash and the statutory rights of pre-emption in section 89 of the Act. The statutory rights of pre-emption apply to the balance of the authorised, but unissued, ordinary share capital of Corp which is not the subject of the disapplication referred to in paragraph 5a.(v) above (including shares reserved for issue in connection with the Warrants) or the share options arrangements referred to in paragraph 2 above. The statutory rights of pre-emption have been disapplied as set out in paragraph 5a.(v) above to: a. permit the Directors to allot the New Shares and Warrants pursuant to the Corp Scheme; b. give the Directors flexibility in relation to pre-emptive offers of Corp shares to ordinary shareholders; and c. permit the Directors to allot Corp Shares for cash following the Corp Scheme becoming effective up to a nominal value of 5 per cent. of the issued ordinary share capital of Corp immediately following the Corp Scheme becoming effective. 7.

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 14 SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP MEMORANDUM The memorandum of association of Corp will be altered conditionally on the allotment of the New Shares pursuant to the Corp Scheme, by the insertion of a new object giving Corp the power to establish and operate share incentive plans and to establish trusts to operate in conjunction with those plans. The Memorandum provides that its objects are, amongst other things, to carry on any business (other than life insurance) which may seem to Corp capable of being conveniently carried on, either in connection with or in addition to any of those referred in the Memorandum. The amended objects of Corp are set out in full in clause 4 of its Memorandum which is available for inspection as described in part I, Section 2, Part D.34. ARTICLES In this Appendix "Statutes" means the Act and every other statute, statutory instrument, regulation or order for the time being in force concerning companies registered under the Act. The Articles of Corp have been adopted conditionally on the allotment of the New Shares pursuant to the Corp Scheme. A summary of certain provisions of the Articles is set out below. For further detail, please refer to the Articles which are available for inspection as described in part 1, Section 2, Part D.34. a. RIGHTS ATTACHING TO CORP SHARES (i) Dividends Subject to the provisions of the Statutes, Corp may by ordinary resolution declare a dividend in accordance with the respective rights of the members, and may fix the time for payment of such dividend provided that no dividend shall exceed the amount recommended by the Corp Board. Except as otherwise provided by the rights attached to shares, all dividends shall be declared and paid according to the amounts paid up on the shares on which the dividend is paid. Except as otherwise provided by the rights attached to shares, all dividends shall be apportioned and paid proportionately according to the amounts paid up on the shares during any portion of the period in respect of which the dividend is paid. Subject to the provisions of the Statutes, Corp may pay interim dividends if it appears to the Corp Board that they are justified by the financial position of Corp. Corp may also pay any dividend payable at a fixed rate at intervals settled by the Corp Board whenever the financial position of Corp, in the opinion of the Corp Board, justifies its payment. If the Corp Board acts in good faith, none of the Directors shall incur any liability to the holders of shares conferring preferred rights for any loss such holders may suffer in consequence of the payment of an interim dividend on any shares having deferred or non-preferred rights. No dividend or other monies payable by Corp on or in respect of a share shall bear interest against Corp unless otherwise provided by the rights attached to the share. There are no fixed dates on which entitlement to dividends arise. The Corp Board may make payment of any interim dividend wholly or partly by the distribution of specific assets and, in particular, including without limitation, of property interests, intellectual property rights or the benefit of contractual or other rights, paid up shares, debentures or debenture stock of any other company or in any one or more of such ways. Where any difficulty arises in regard to such distribution, the Corp Board may settle the same as it thinks expedient. A general meeting declaring a dividend may, on the recommendation of the Corp Board, by ordinary resolution, direct that payment of any dividend may be satisfied in whole or in part by the distribution of specific assets, including without limitation paid up shares or debentures of another body corporate. The Corp Board may make any arrangements it thinks fit to settle any difficulty arising in connection with 835

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 14: SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP -------------------------------------------------------------------------------- such distribution. The Corp Board may, if authorised by an ordinary resolution of Corp, offer any holders of shares the right to elect to receive further shares (whether or not of that class) credited as fully paid instead of cash in respect of any dividend or part thereof. The offer shall be on the terms and be made in the manner specified in the Articles. All unclaimed dividends, interest or other sums payable may be invested or otherwise made use of by the Board for the benefit of Corp until claimed. Any dividend which has remained unclaimed for twelve years from the date when it became due for payment shall, if the Corp Board so resolves, be forfeited and shall cease to remain owing by Corp. Corp may cease sending dividend warrants and cheques by post or otherwise to a member if such instruments have been returned undelivered to, or left uncashed by, that member on at least two consecutive occasions, or, following one such occasion, reasonable enquiries have failed to establish any new address of the member. Corp must resume sending warrants and cheques if the member claims a dividend or cashes a dividend warrant or cheque. (ii) Voting rights Subject to the Articles and to any rights or restrictions as to voting for the time being attached to any class of shares, on a show of hands, every member who is present in person or by proxy or (being a corporation) is present by a duly authorised corporate representative, not being himself a member, at a general meeting, shall have one vote and, on a poll, every member present in person or by proxy or (being a corporation) is present by a duly authorised corporate representative shall have one vote for every share of which he is the holder. Save that where a member appoints more than one proxy to attend on the same occasion with respect to different shares, the proxies so appointed shall not be entitled to vote on a show of hands in the case of a special or extraordinary resolution. Unless the Corp Board otherwise decides, no member shall be entitled to vote at a general meeting or at a separate meeting of the holders of any class of shares in the capital of Corp, either in person or by proxy, in respect of any share held by him unless all monies presently payable by him in respect of that share have been paid. (iii) Rights attaching to Corp Shares on a distribution of assets On a winding-up of Corp, the liquidator may, with the sanction of an extraordinary resolution and any other sanction required by the Insolvency Act 1986, divide among the members in specie the whole or any part of the assets of Corp in such manner as he may determine or vest the whole or any part of the assets in trustees upon such trusts for the benefit of the members as he, with like sanction, determines. No member shall be compelled to accept any assets on which there is a liability. (iv) Transfer of Corp Shares All transfers of Corp shares held in certificated form may be effected by an instrument of transfer in any usual form or in any other form approved by the Corp Board. The instrument of transfer of a share shall be signed by or on behalf of the transferor and, unless the share is fully paid, or is a forfeited or surrendered share, by or on behalf of the transferee. The Corp Board may, in its absolute discretion and without giving any reason for its decision, refuse to register any instrument of transfer of a certified share which is not fully paid up (but, in the case of a class of shares which has been admitted to the Official List, not so as to prevent dealings in the shares from taking place on an open and proper basis) or on which Corp has a lien. Subject to the requirements of the UK Listing Authority, the Corp Board may also refuse to register any instrument of transfer unless: (A) it is lodged, duly stamped (if stampable), at the registered office or at such other place as the Corp Board may appoint accompanied by the share certificate for the shares to which it relates and such other evidence (if any) as the Corp Board may reasonably require to show the right of the transferor to make the transfer; 836

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 14: SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP -------------------------------------------------------------------------------- (B) it is in respect of only one class of shares; and (C) it is in favour of not more than four transferees as joint holders. Corp shall register the transfer of any shares held in uncertificated form in accordance with the Statutes. The Board may, in its absolute discretion and without giving any reason for its decision, refuse to register any transfer of an uncertificated share where permitted by the Statutes. If the Corp Board refuses to register a transfer of a share, it shall give the transferee notice of its refusal within two months after the date on which the instrument of transfer was lodged with Corp or the operator-instruction was received, as the case may be. The registration of transfers of any shares or any class of shares may be suspended at such times and for such periods (not exceeding 30 days in any year) as the Corp Board may determine, except that the registration of transfers of any shares or any class of shares which are for the time being participating securities may only be suspended as permitted by the Statutes. b. DISCLOSURE OF INTERESTS IN SHARES If the holder of or other person appearing to be interested in any share of Corp has been duly given a notice under section 212 of the Act and, in respect of that share, has been in default for a period of fourteen days after such notice has been given in supplying to Corp the information thereby required, then certain restrictions shall apply. The restrictions available are the suspension of voting or other rights conferred by membership in relation to meetings of Corp in respect of the relevant shares and, additionally, in the case of a shareholding representing at least 0.25 per cent. of the class of shares concerned, the withholding of payment of dividends on, and the restriction of transfers of, the relevant shares. The restrictions on transfer shall not prejudice the right of either the member holding the shares or, if different, any person having a power of sale over those shares to sell or agree to sell those shares under an exempt transfer. c. CHANGES IN SHARE CAPITAL (i) Subject to the Statutes and without prejudice to any rights attached to any existing shares or class of shares, any share may be issued with such rights or restrictions as Corp may by ordinary resolution determine or, subject to and in default of such determination, as the Corp Board shall determine. Subject to the provisions of the Statutes and without prejudice to any rights attached to any existing shares, Corp may issue shares which are, or at the option of Corp or the holder are, liable to be redeemed. Subject to the provisions of the Statutes and the Articles, unissued shares are at the disposal of the Corp Board. (ii) Corp may by ordinary resolution: increase the share capital; consolidate and divide all or any of its share capital into shares of larger amounts than its existing shares; subject to the Statutes, subdivide its shares, or any of them, into shares of smaller amount than is fixed by the Memorandum or the Articles; and cancel any shares which have not been taken or agreed to be taken by any person and diminish the amount of its share capital by the amount of the shares so cancelled. (iii) Whenever any members are entitled to fractions of a share as a result of a consolidation and division or sub-division of shares, the Corp Board may deal with the fractions as it thinks fit. (iv) Subject to the Statutes and to any relevant rights attached to any class of shares, Corp may by special resolution reduce its share capital, any capital redemption reserve and any share premium account and may also, subject to the Statutes, the requirements of the UK Listing Authority, and the rights attached to any class of shares, purchase its own shares. 837

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 14: SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP -------------------------------------------------------------------------------- d. VARIATION OF RIGHTS (i) If at any time the capital of Corp is divided into different classes of shares, all or any of the rights for the time being attached to any class of shares in issue may from time to time (whether or not Corp is being wound up) be varied in such manner as those rights may provide or (if no such provision is made) either with the consent in writing of the holders of three-fourths in nominal value of the issued shares of that class or with the authority of an extraordinary resolution passed at a separate general meeting of the holders of those shares. (ii) Unless otherwise expressly provided by the rights attached to any class of shares those rights shall not be deemed to be varied by the creation or issue of further shares ranking pari passu with them or by the purchase or redemption by Corp of any of its own shares. e. LIEN AND FORFEITURE Corp will have a first and paramount lien on every share (not being a fully paid share) for all amounts payable to Corp (whether presently or not) in respect of that share. Subject to the Articles, the Corp Board may call any monies unpaid on shares and may forfeit shares on which calls payable are not duly paid. The forfeiture shall include all dividends declared and other monies payable in respect of the forfeited share which have not been paid before the forfeiture. f. CORP DIRECTORS' INTERESTS (i) A Corp Director shall not vote (or be counted in the quorum at a meeting) in relation to any resolution relating to any contract or arrangement or other proposal in which he has an interest which (together with any interest of any person connected to him) is to his knowledge a material interest and, if he purports to do so, his vote shall not be counted, but the prohibition shall not apply and a Corp Director may vote (and be counted in the quorum) in respect of any resolution concerning any one or more of the following matters: (A) any contract in which he is interested by virtue of an interest in shares, debentures or other securities of Corp or otherwise in or through Corp; (B) the giving of any guarantee, security or indemnity in respect of money lent or obligations incurred by him or by any other person at the request of, or for the benefit of, Corp or any of its subsidiary undertakings or a debt or obligation of Corp or any of its subsidiary undertakings for which he himself has assumed responsibility in whole or in part (either alone or jointly with others) under a guarantee or indemnity or by the giving of security; (C) any issue or offer of shares, debentures or other securities of Corp or any of its subsidiary undertakings in respect of which he is or may be entitled to participate in his capacity as a holder of any such securities or as an underwriter or sub-underwriter; (D) any contract concerning any other company in which he and any connected persons do not to his knowledge hold an interest in shares (within the meaning of sections 198 to 211 of the Companies Act) representing one per cent. or more of any class of the equity share capital of that company or of the voting rights available to members of that company; (E) any arrangement for the benefit of employees of Corp or any of its subsidiary undertakings which does not accord to him any privilege or benefit not generally accorded to the employees to whom the arrangement relates; and (F) the purchase or maintenance of insurance for the benefit of the Corp Directors or for the benefit of persons including the Corp Directors. (ii) A Corp Director shall not vote (or be counted in the quorum at a meeting) in respect of any resolution concerning his own appointment (including fixing or varying its terms) or the termination of his own appointment, as the holder of any office or place of profit with Corp or any other company in which Corp is interested. 838

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 14: SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP -------------------------------------------------------------------------------- g. REMUNERATION OF CORP DIRECTORS (i) The fees of the Non-Executive Corp Directors for their services (excluding amounts payable under any other provision of the Articles described below) shall not exceed in aggregate L1.5 million per annum or such higher amount as Corp may from time to time by ordinary resolution determine. Subject thereto, each such Non-Executive Corp Director shall be paid a fee (which shall be deemed to accrue from day to day) at such rate as may from time to time be determined by the Corp Board. Any Corp Director who is appointed to any executive office shall be entitled to receive such remuneration as the Corp Board may determine. (ii) Any Corp Director who does not hold executive office and who serves on any committee of the Corp Board, who by the request of the Corp Board goes or resides abroad for any purpose of Corp or otherwise performs special services which in the opinion of the Corp Board are outside the scope of the ordinary duties of a Non-Executive Corp Director, may (without prejudice to subparagraph (i) above) be paid such extra remuneration by way of salary, commission or otherwise as the Corp Board may determine. (iii) The Corp Board may exercise all the powers of Corp to pay, provide or procure the grant of benefits, whether by the payment of gratuities, pensions or by insurance or otherwise, for any past or present Corp Director or employee of Corp or any company which is or was the holding company, subsidiary or associated company, and for any member of his family (including a spouse and a former spouse), or any person who is or was dependent on him and may (as well before as after he ceases to hold such office or employment) contribute to any fund and pay premiums for the purchase or provision of any such benefit. (iv) Without the prior approval by ordinary resolution of the shareholders in general meeting, no bonus arrangement or scheme or any long term incentive scheme for persons who are participants in the Management Plan (other than participants who are eligible to receive commission and/or bonus payments that relate to sales) shall be introduced within the period commencing with the date on which the Articles come into force and ending on the date on which all the tranches of options granted in the initial grant under the Management Plan have either lapsed or become capable of exercise. (v) The Corp Directors may be paid by Corp all travelling, hotel and other expenses properly incurred by them in attending meetings of the Corp Board or committees of the Corp Board or general meetings or otherwise in connection with the discharge of their duties. h. APPOINTMENT AND RETIREMENT OF CORP DIRECTORS (i) Corp Directors may be appointed by Corp by ordinary resolution or by the Corp Board. Unless otherwise determined by ordinary resolution, the number of Corp Directors (other than alternate directors) shall not be less than three nor more than twenty-four in number. (ii) At each annual general meeting any Corp Director then in office who has been appointed by the Corp Board since the previous annual general meeting or at the date of the annual general meeting would have held office for more than three years since he was appointed or last re-appointed by Corp in a general meeting shall retire from office but shall be eligible for re-appointment. (iii) A Director shall retire at the first annual general meeting following the birthday at which he attains 70 years of age. A Director may be re-appointed after attaining 70 years of age provided that he is appointed by Corp in general meeting, special notice is given of the resolution appointing the Director and the notice states the age of the prospective Director. A Director who is re-appointed after attaining 70 years of age must retire at every annual general meeting thereafter but may be re-appointed in accordance with the procedure set out above. 839

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 14: SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP -------------------------------------------------------------------------------- i. BORROWING POWERS (i) The Corp Board may exercise all the powers of Corp to borrow money, to guarantee, to indemnify, to mortgage or charge all or any part of its undertaking, property, assets (both present and future) and uncalled capital, and to issue debentures and other securities whether outright or as collateral security for any debt, liability or obligation of Corp or of any third party. (ii) The Corp Board shall restrict the borrowings of Corp and exercise all voting and other rights or powers of control exercisable by Corp in relation to its subsidiary undertakings (if any) so as to secure (but as regards subsidiary undertakings only so far as by such exercise it can secure) that the aggregate principal amount outstanding at any time in respect of all borrowings by the Group (exclusive of any borrowings which are owed by one Group company to another Group company) after deducting the amount of cash at the bank and in hand will not, without the previous authority of Corp in general meeting exceed the higher of an amount equal to two times adjusted capital and reserves (as defined in the Articles) or L1.5 billion (or any higher limit fixed by ordinary resolution of Corp which is applicable at the relevant time). (iii) The limits set out in sub-paragraphs (i) and (iii) immediately above shall be deemed not to have been breached until the amount of borrowings has exceeded that limit for 30 consecutive days and this provision overrides all other provisions of the relevant article. j. INDEMNITY OF OFFICERS Subject to the Statutes but without prejudice to any indemnity to which a Corp Director may otherwise be entitled, every Corp Director or other officer (excluding an auditor) shall be indemnified out of the assets of Corp against any liability incurred by him in defending any proceedings whether criminal or civil in which judgement is given in his favour (or the proceedings are otherwise disposed of without any finding or admission of any material breach of duty on his part) or in which he is acquitted or in connection with any application in which relief is granted to him by the Court from liability for negligence, default, breach of duty or breach of trust in relation to the affairs of Corp. k. UNTRACED SHAREHOLDERS Corp shall be entitled to sell, at the best price reasonably obtainable, the shares of a member or the shares to which a person is entitled by transmission provided that: (i) during a period of twelve years prior to the date of advertising its intention to sell such shares at least three dividends in respect of such shares have been declared and all dividend warrants and cheques sent have remained uncashed; (ii) as soon as practicable after the expiry of the period referred to in sub-paragraph (i) above Corp inserts advertisements in a national daily newspaper and in a newspaper circulating in the area of the last known address of the member or other person giving notice of its intention to sell the shares; (iii) during the period referred to in sub-paragraph (i) above and the period of three months following the publication of the advertisements referred to in sub-paragraph (ii) above Corp receives no indication of the whereabouts or existence of the member or other person; and (iv) if the shares are listed on the London Stock Exchange's market for listed securities, Corp gives notice to the London Stock Exchange of its intention to sell the shares prior to publication of the advertisements referred to in sub-paragraph (ii) above. The net proceeds of such sale shall belong to Corp, which shall be obliged to account to the former member or other person previously entitled to the shares for an amount equal to the proceeds as a creditor of Corp. 840

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 14: SUMMARY OF CERTAIN PROVISIONS OF THE MEMORANDUM AND ARTICLES OF CORP -------------------------------------------------------------------------------- l. NOTICES TO MEMBERS Except where otherwise expressly provided within the Articles, any notice to be given to or by any person under the Articles shall be in writing or, to the extent permitted by the Statutes and subject to the Articles, contained in an electronic communication. The Corp Board may from time to time specify the form and manner in which a notice may be given to the members by electronic means and a notice may be given to the members by electronic means only if it is given in accordance with the requirements specified by the Corp Board. A notice in writing, document or other communication may be given or served by Corp to any member either personally or by sending it through the post addressed to the member at his registered address or by leaving it at that address. A member whose registered address is not within the United Kingdom shall be entitled to have notices given to him at that address if, at the time of giving that notice, he is the registered holder of one per cent. or more of the issued share capital of Corp. Any other member whose registered address is not within the United Kingdom and who gives Corp an address within the United Kingdom at which notices may be given to him shall be entitled to have notices given to him at that address but, unless he does so, shall not be entitled to receive any notice from Corp. 841

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 15 RIGHTS AND RESTRICTIONS ATTACHING TO THE NON-VOTING DEFERRED SHARES A Non-Voting Deferred Share: a. does not entitle its holder to receive any dividend or other distribution; b. does not entitle its holder to receive notice of or to attend or vote at any general meeting of Corp; c. entitles its holder on a return of capital on a winding-up (but not otherwise) only to repayment of the amounts paid up on that share after payment in respect of each ordinary share of the capital paid up on it and the further payment of L10,000,000 on each ordinary share; and d. does not entitle its holder to any further participation in the capital of Corp. 842

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 16 DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS This Appendix sets out a summary of the material terms of the ADRs. For information with respect to the issuance of ADRs pursuant to the Schemes, the listing of the ADRs on NASDAQ and trading of ADRs in the secondary market, please see part I, Section 2, Parts C.2 and D.15. The Bank of New York, as depositary (the "ADR Depositary"), will issue the ADRs. Each ADR represents an ownership interest in 10 Corp Shares, or evidences the right to receive 10 Corp Shares. Corp will deposit the Corp Shares (or the right to receive such shares) with the custodian, the principal London office of The Bank of New York (together with any successor or successors thereto, the "Custodian"), currently located at 1 Canada Square, Canary Wharf, London E14 5AL, England. Each ADR will also represent securities, cash or other property deposited with The Bank of New York but not distributed to ADR holders. The Bank of New York's Corporate Trust office is located at 101 Barclay Street, New York, NY 10286. The Bank of New York's principal executive office is located at One Wall Street, New York, NY 10286. ADRs may be held either directly or indirectly through a broker or other financial institution. The discussion below assumes the ADRs are held directly, in which case the direct holder is referred to as the "ADR holder". Only persons in whose names ADRs are registered on the books of the ADR Depositary will be treated by the ADR Depositary and Corp as ADR holders. If the ADRs are held indirectly, then the procedures of the broker or other financial institution must be relied on to assert the rights of ADR holders described in the discussion below. Holders should consult with their broker or financial institution to find out what those procedures are. Because The Bank of New York will actually hold the Corp Shares, direct and indirect holders of ADRs must rely on it to exercise the rights of a shareholder. The obligations of The Bank of New York will be set out in a Deposit Agreement among Corp, The Bank of New York, as depositary, ADR holders, and the owners of beneficial interests in the ADRs (the "Deposit Agreement"). The agreement and the ADRs are generally governed by New York law. The following is a summary of the Deposit Agreement (including all exhibits thereto). This summary does not purport to be complete and is qualified in its entirety by reference to the Deposit Agreement. Copies of the Deposit Agreement and the ADR are available for inspection at the principal London office of The Bank of New York, currently located at 1 Canada Square, Canary Wharf, London E14 5AL, England and at The Bank of New York's Corporate Trust office, currently located at 101 Barclay Street, New York, NY 10286. Terms used herein and not otherwise defined shall have the meanings set forth in the Deposit Agreement. IMPORTANT NOTICE REGARDING RESPONSIBILITY FOR FEES AND TAXES PERSONS ELECTING TO RECEIVE ADRS PURSUANT TO THE SCHEMES Scheme Creditors and Designated Recipients who receive New Shares in the form of ADRs pursuant to the Schemes at any time will not be responsible for any fees or expenses of The Bank of New York, or any UK stamp duty or SDRT, in respect of the initial issuance of such ADRs. The Bank of New York has agreed to waive its fees and expenses in this connection, and any such UK stamp duty or SDRT will be met by Corp. Such persons will, however, be responsible for any other taxes or charges arising in connection with such initial issuance of ADRs, as well as any fees, expenses, taxes or charges arising in connection with any subsequent transaction involving ADRs (except to the extent described below under "General fee holiday"). PERSONS ELECTING TO RECEIVE NEW SHARES PURSUANT TO THE SCHEMES Subject to compliance with the procedures referred to below, Scheme Creditors and Designated Recipients who receive New Shares pursuant to the Schemes will not be responsible for any fees or expenses of The Bank of New York in respect of the initial issuance of ADRs upon deposit of those New Shares (or an equivalent number of Corp Shares) in exchange for ADRs, if such deposit is effected prior to the earlier of (x) the date falling two months after the effectiveness of the NASDAQ listing of the ADRs and (y) 30 September 2003. The Bank of New York has agreed to waive its fees and expenses in this connection. 843

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- In addition, subject to compliance with the procedures referred to below, Scheme Creditors and Designated Recipients who receive New Shares pursuant to the Schemes will not be responsible for any UK stamp duty or SDRT arising in connection with the initial issuance of ADRs upon deposit of those New Shares (or an equivalent number of Corp Shares) in exchange for ADRs, if such deposit is effected prior to the date falling two month after the effectiveness of the NASDAQ listing of the ADRs. Any such UK stamp duty or SDRT will be met by Corp. To qualify for the treatment described above, Scheme Creditors and Designated Recipients must comply with certain procedures, including providing such certifications or other evidence as Corp and The Bank of New York may reasonably require in order to permit verification of the number of New Shares obtained by the depositor pursuant to the Schemes. For information with respect to the relevant procedures, Scheme Creditors and Designated Recipients should contact The Bank of New York's office in London on (attention Mr Peter Ridgwell), telephone +44 207 964 6168, facsimile +44 207 964 6043. Except insofar as these arrangements apply, Scheme Creditors and Designated Recipients will be responsible for all taxes or charges arising in connection with the initial issuance of ADRs as described above, as well as any fees, expenses, taxes or charges arising in connection with any subsequent issuance of or other transaction involving ADRs (except to the extent described below under "General fee holiday"). GENERAL FEE HOLIDAY The Bank of New York has agreed to waive any payment in respect of its fees and expenses that would otherwise be required under the Deposit Agreement in connection with any deposit of Corp Shares in exchange for ADRs that is effected prior to the date falling two months after the Effective Date of the Corp Scheme. This "fee holiday" will be implemented without regard to the special arrangements for Scheme Creditors and Designated Recipients described above. Persons depositing Corp Shares during this period (other than Scheme Creditors and Designated Recipients, to the extent described above) will, however, be responsible for any taxes or other charges (including UK stamp duty or SDRT) arising in connection with the issuance of ADRs. SHARE DIVIDENDS AND OTHER DISTRIBUTIONS The Bank of New York has agreed to pay to the ADR holders the cash dividends or other distributions it or the Custodian receives on shares or other deposited securities after deducting its fees and expenses. Each ADR holder will receive these distributions in proportion to the number of shares its ADRs represent. CASH The Bank of New York will convert any cash dividend or other cash distribution Corp pays on the Corp shares into US dollars, if it can do so on a reasonable basis and can transfer the US dollars to the US. If that is not possible or if any approval from the UK government is needed and cannot be obtained, the agreement allows The Bank of New York, following consultation with Corp, to distribute the sterling only to those ADR holders to whom it is possible to do so. It will hold the sterling it cannot convert for the account of the ADR holders who have not been paid. It will not invest the sterling and it will not be liable for interest. Before making a distribution, any withholding taxes that must be paid under English law will be deducted. For a further description of tax considerations, refer to Appendix 17. The Bank of New York will distribute only whole US dollars and cents and will round fractional cents to the nearest whole cent. If the exchange rates fluctuate during a time when The Bank of New York cannot convert the UK's currency, some or all of the value of the distribution may be lost. SHARES The Bank of New York may, and shall if Corp requests distribute new ADRs representing any Corp Shares Corp may distribute as a dividend or free distribution, if Corp furnishes it promptly with satisfactory evidence that it is legal to do so. The Bank of New York will only distribute whole ADRs. It will sell shares which would require it to deliver a fractional ADR and distribute the net proceeds in the same way as it does with cash. If The Bank of 844

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- New York does not distribute additional ADRs, each ADR will also represent the proportional number of new Corp Shares. RIGHTS TO RECEIVE ADDITIONAL SHARES If Corp offers holders of Corp Shares any rights to subscribe for additional shares or any other rights, The Bank of New York, after consultation with Corp, will have discretion as to the procedure to be followed in making these rights available to the ADR holder or in disposing of such rights for the benefit of any ADR holders and making the net proceeds available to such ADR holders. However, if by the terms of such rights offering or by reason of applicable law, The Bank of New York may not either make such rights available to any ADR holders or dispose of such rights and make net proceeds available to such ADR holders, then The Bank of New York shall allow the rights to lapse. In that case, the ADR holder will receive no value for them. In circumstances in which rights would not otherwise be distributed, if any ADR holder requests the distribution of warrants or other instruments in order to exercise the rights allocable to the ADRs of such holder, The Bank of New York will make such rights available to such ADR holder as promptly as practicable upon written notice from Corp to The Bank of New York that (i) Corp has elected in its sole discretion to permit such rights to be exercised and (ii) such holder has executed such documents as Corp has determined in its sole discretion are reasonably required under applicable law. If The Bank of New York makes rights available to the ADR holder, upon instruction from such ADR holder, it will exercise the rights and purchase the shares on the ADR holder's behalf. The Bank of New York will then deposit the shares and issue ADRs to the ADR holder. It will only exercise rights if the ADR holder pays to The Bank of New York the exercise price and any other charges the rights require to be paid, as well as The Bank of New York's fees. US securities laws may restrict the sale, deposit, cancellation and transfer of the ADRs issued after exercise of rights. For example, an ADR holder may not be able to trade the ADRs freely in the US. In this case, The Bank of New York may issue the ADRs under a separate restricted deposit agreement which will contain the same provisions as the Deposit Agreement, except for the changes needed to put the restrictions in place. OTHER DISTRIBUTIONS The Bank of New York will send to the ADR holder anything else Corp distributes in respect of deposited securities by any means it thinks is legal, fair and practical. If it cannot make the distribution in that way, The Bank of New York has a choice. Following consultation with Corp, it may decide to sell what Corp distributed and distribute the net proceeds in the same way as it does with cash or it may decide to hold what Corp distributed, in which case the ADRs will also represent the newly distributed property. The Bank of New York is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADR holders. Corp has no obligation to register ADRs, shares, rights or other securities under the Securities Act. Corp also has no obligation to take any other action to permit the distribution of ADRs, shares, rights or anything else to ADR holders. This means that the ADR holder may not receive the distribution Corp makes on its shares or any value for them if it is illegal or impractical for Corp to make them available to the ADR holder. DEPOSIT, WITHDRAWAL AND CANCELLATION The Bank of New York will issue ADRs if the ADR holder or its broker deposits shares or evidence of rights to receive shares with the Custodian. Subject to the special arrangements relating to the Restructuring described above under "Important notice regarding responsibility for fees and taxes," upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, The Bank of New York will register the appropriate number of ADRs in the names requested by the ADR holder and will deliver the ADRs at its Corporate Trust office to the persons requested by the ADR holder. The ADR holder may turn in its ADRs at The Bank of New York's Corporate Trust office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, The Bank of 845

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- New York will deliver the underlying Corp Shares to an account designated by the ADR holder and any other deposited securities underlying the ADR at the office of the custodian. Or, at the ADR holder's request, risk and expense, The Bank of New York will deliver the deposited securities at its Corporate Trust office. RECORD DATES The ADR Depositary will, after consultation with Corp if practicable, fix a record date (which will be as near as practicable to any corresponding record date set by Corp) for the determination of the ADR holders who will be entitled to receive any distribution on or in respect of the deposited Corp Shares or the net proceeds thereof, to give instructions for the exercise of any voting rights in respect of those Corp Shares, to receive any notice or to act in respect of other matters and only such ADR holders at the close of business on such record date will be so entitled. VOTING RIGHTS The ADR holder may instruct The Bank of New York to vote the Corp Shares underlying the ADRs unless Corp requests otherwise. If Corp makes such a request, an ADR holder will not be able to exercise its right to vote unless it withdraws the Corp Shares underlying its ADRs. There can be no assurance that the ADR holder will receive notice of the meeting enough in advance to withdraw its shares. Unless instructed otherwise by Corp, The Bank of New York will notify the ADR holders of the upcoming vote and arrange to deliver Corp's voting materials to the ADR holders. The materials will describe the matters to be voted on and explain how each ADR holder, on a certain date, may instruct The Bank of New York to vote the Corp Shares or other deposited securities. For instructions to be valid, The Bank of New York must receive them on or before the date specified. The Bank of New York will try, as far as practical, subject to English law and the provisions of Corp's Memorandum and Articles, to vote or to have its agents vote the Corp Shares or other deposited securities as the ADR holder instructs. The Bank of New York will only vote or attempt to vote as the ADR holder instructs. However, if The Bank of New York does not receive the ADR holder's voting instructions, it will give a proxy to vote their Corp Shares to Corp's designated representative. A proxy will not be given with respect to any matter as to which Corp informs The Bank of New York in writing that Corp does not wish such proxy to be given. Corp cannot assure that the ADR holder will receive the voting materials in time to ensure that it can instruct The Bank of New York to vote their Corp Shares. In addition, The Bank of New York and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that the ADR holder may not be able to exercise their right to vote and there may be nothing the ADR holder can do if the shares are not voted as requested. DISCLOSURE OF INTERESTS The ADR holder is deemed in the agreement to have agreed to provide any information Corp may request in a disclosure notice given pursuant to the Act and Corp's Memorandum and Articles. If the ADR holder does not provide the information requested in a disclosure notice and the ADR holder is (or appears to be) an interested person under the Act and its Memorandum and Articles, Corp may impose sanctions. These sanctions currently could include: a. the withdrawal of the ADR holder's voting rights under the Corp Shares; b. the withholding of dividends and other capital payments on the Corp Shares; and c. the restriction of the ADR holder's right to transfer their Corp Shares. The ADR holder must also notify Corp as required by the Act if it becomes interested in 3 per cent. or more of the Corp Shares, or if the ADR holder becomes aware that any person or persons that it is holding ADRs for becomes so interested, or if subsequent changes in the ADR holder's or their interest with respect to the Corp Shares occur. The ADR holder must notify Corp within two UK business days after becoming interested or aware that another person is interested in 3 per cent. or more of the Corp Shares. After that time, the ADR holder must 846

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- notify Corp of any change of at least 1 per cent. of Corp Shares. If the ADR holder fails to do so, Corp may impose sanctions against the ADR holder similar to those described above. FEES AND EXPENSES Subject to the special arrangements relating to the Restructuring described above under "Important notice regarding responsibility for fees and taxes": <Table> <Caption> ADR holders must pay: For: --------------------- ---- <S> <C> US$5.00 (or less) per 100 ADRs Each issue of an ADR, including as a result of a distribution of shares or rights or other property Each cancellation of an ADR, including if the Deposit Agreement terminates US$0.02 (or less) per ADR Any cash payment, except for distributions of cash dividends Registration or transfer fees Registration and transfer of shares on the share register of Corp's registrar, Computershare Services, from the holder's name to the name of The Bank of New York or its agent when shares are deposited or withdrawn Expenses of The Bank of New York Conversion of sterling to US dollars and cable, telex and facsimile transmission expenses Taxes and other governmental charges The As necessary Bank of New York or the Custodian have to pay on any ADR or share underlying an ADR, for example, stock transfer taxes, stamp duty or withholding taxes </Table> PAYMENT OF TAXES Subject to the special arrangements relating to the Restructuring described above under "Important notice regarding responsibility for fees and taxes," the ADR holder will be responsible for any taxes or other governmental charges payable on its ADRs or on the deposited securities underlying its ADRs. The Bank of New York may refuse to transfer an ADR holder's ADRs or allow it to withdraw the deposited securities underlying its ADRs until such taxes or other charges are paid. It may apply payments owed to the ADR holder or sell deposited securities underlying the ADRs to pay any taxes owed and the ADR holder will remain liable for any deficiency. If The Bank of New York sells deposited securities, it will, if appropriate, reduce the number of ADRs to reflect the sale and pay to the ADR holder any proceeds, or send to you any property, remaining after it has paid the taxes. 847

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- RECLASSIFICATIONS, RECAPITALISATIONS AND MERGERS <Table> <Caption> If Corp does any of the following: Then: ---------------------------------- ----- <S> <C> Change the nominal or par value of the Corp The cash, shares or other securities Shares received by The Bank of New York will become deposited securities. Each ADR will Reclassify, split-up or consolidate any of automatically represent its equal share of the deposited securities the new deposited securities. Distribute securities on the shares that are The Bank of New York may, and will if Corp not distributed to holders asks it to, distribute some or all of the cash, shares or other securities it Recapitalise, reorganise, merge, liquidate, received. It may also issue new ADRs or ask sell all or substantially all of Corp's holders to surrender their outstanding ADRs assets, or take any similar action in exchange for new ADRs, identifying the new deposited securities. </Table> REPORTS AND OTHER COMMUNICATIONS The ADR Depositary has undertaken to make available at its Corporate Trust offices in the US, for inspection by Corp and the ADR holders, the Deposit Agreement and any reports, notices and written communications received from Corp which are made generally available to the holders of such deposited Corp shares by Corp. The ADR Depositary has agreed to mail copies of such reports, notices and communications (or English translations or summaries thereof) to ADR holders when furnished by Corp. Corp has agreed to transmit to the ADR Depositary, on or before the first date on which Corp makes any communication available to holders of Corp Shares, a copy (in English or with an English translation or summary) of any communications it makes generally available (by publication or otherwise) to holders of Corp shares. Corp has delivered to the ADR Depositary and the Custodian a copy of its Memorandum and Articles and all other provisions adopted by it or governing Corp Shares and any other deposited securities issued by Corp or any Affiliate of Corp and, promptly upon any change thereto, Corp will deliver a copy of such provisions as so changed. All copies will be in English or accompanied by English translations. Corp has agreed that the ADR Depositary and its agents may rely upon Corp's delivery of all such communications, information and provisions for all purposes of the Deposit Agreement. AMENDMENT AND TERMINATION Corp may agree with The Bank of New York to amend the Deposit Agreement and the ADRs without the ADR holders' consent for any reason. If the amendment adds or increases fees or charges, except for taxes and other governmental charges or registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses, or prejudices an important right of ADR holders, it will only become effective 30 days after The Bank of New York notifies the ADR holders of the amendment. At the time an amendment becomes effective, the ADR holder is considered, by continuing to hold its ADRs, to agree to the amendment and to be bound by the ADRs and the Deposit Agreement is amended. The Bank of New York will terminate the Deposit Agreement if Corp asks it to do so. The Bank of New York may also terminate the Deposit Agreement if The Bank of New York has told Corp that it would like to resign and Corp has not appointed a new depositary bank within 90 days. In both cases, The Bank of New York must notify the ADR holders at least 30 days before termination. No amendment will impair the right of ADR holders to surrender their ADRs and receive the underlying shares unless such an impairment is necessary in order to comply with mandatory provisions of applicable law. After termination, The Bank of New York and its agents will be required to only collect distributions on the deposited securities and deliver shares and other deposited securities upon cancellation of ADRs. At any time after one year from the date of termination, The Bank of New York may sell property and rights and convert deposited securities into cash by public or private sale. After that, The Bank of New York will hold the 848

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- proceeds of the sale, as well as any other cash it is holding under the agreement for the pro rata benefit of the ADR holders that have not surrendered their ADRs. It will not invest the money and will have no liability for interest. The Bank of New York's only obligations will be to account for the proceeds of the sale and other cash. After termination Corp's only obligations will be with respect to indemnification and to pay certain amounts to The Bank of New York. LIMITATIONS ON OBLIGATIONS AND LIABILITY TO ADR HOLDERS The Deposit Agreement expressly limits Corp's obligations and the obligations of The Bank of New York, and it limits Corp's liability and the liability of The Bank of New York. Corp and The Bank of New York: a. are only obligated to take the actions specifically set forth in the agreement without negligence, wilful misconduct or bad faith; b. are not liable if either is prevented or delayed by law or circumstances beyond their control from performing their obligations under the agreement; c. are not liable if either exercises discretion permitted under the agreement; d. have no obligation to become involved in a lawsuit or other proceeding related to the ADRs or the agreement on your behalf or on behalf of any other party; and e. may rely upon any documents they believe in good faith to be genuine and to have been signed or presented by the proper party. In the Deposit Agreement, Corp and The Bank of New York agree to indemnify each other under certain circumstances. REQUIREMENTS FOR ADR DEPOSITARY ACTIONS Before The Bank of New York will issue or register transfer of an ADR, make a distribution on an ADR, or withdrawal of shares, The Bank of New York may require: a. payment of stock transfer or other taxes or other governmental charges and transfer, registration or conversion fees charged by third parties for the transfer of any shares or other deposited securities as well as The Bank of New York's fees; b. production of satisfactory proof of the identity and genuineness of any signature or other information it deems necessary; and c. compliance with regulations it may establish, from time to time, consistent with the agreement, including presentation of transfer documents. The Bank of New York may refuse to deliver, transfer, or register transfers of ADRs generally when the books of The Bank of New York or Corp's transfer books are closed, or at any time if The Bank of New York or Corp think it advisable to do so. ADR holders have the right to cancel their ADRs and withdraw the underlying shares at any time except: a. when temporary delays arise because: (i) The Bank of New York or Corp has closed its or Corp's transfer books; (ii) the transfer of shares is blocked to permit voting at a shareholders' meeting; or (iii) Corp is paying a dividend on the shares; b. when ADR holders seeking to withdraw shares owe money to pay fees taxes and similar charges; or c. when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADRs or to the withdrawal of shares or other deposited securities. This right of withdrawal may not be limited by any other provision of the Deposit Agreement. 849

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 16: DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS -------------------------------------------------------------------------------- PRE-RELEASE OF ADRS Unless requested by Corp to cease doing so, in certain circumstances, subject to the provisions of the Deposit Agreement and any limitations established by The Bank of New York, The Bank of New York may issue ADRs before deposit of the underlying Corp Shares. This is called a pre-release of the ADR. The Bank of New York may also deliver Corp Shares upon cancellation of pre-released ADRs (even if the ADRs are cancelled before the pre-release transaction has been closed out). A pre-release is closed out as soon as the underlying Corp Shares are delivered to The Bank of New York. The Bank of New York may receive ADRs instead of Corp Shares to close out a pre-release. The Bank of New York may pre-release ADRs only under the following conditions: a. before or at the time of the pre-release, the person to whom the pre-release is being made must represent to The Bank of New York in writing that the person or its customer (i) owns the Corp Shares or ADRs to be deposited; (ii) assigns all beneficial rights, title and interest in the Corp Shares or ADRs to The Bank of New York for the benefit of the transferee; and (iii) will not take any action relating to the Corp Shares or ADRs that is inconsistent with the transfer of beneficial ownership; b. the pre-release must be fully collateralised (such collateral marked to market daily) with cash, US government securities or other collateral that The Bank of New York determines, in good faith, will provide substantially similar liquidity and security; and c. The Bank of New York must be able to close out the pre-release on not more than five business days' notice. In addition, The Bank of New York will limit the number of ADRs that may be outstanding at any time as a result of pre-release (this number will not normally exceed 20 per cent. of the shares deposited under the agreement), although The Bank of New York may disregard the limit from time to time, if it thinks it is appropriate to do so. 850

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 17 TAX This Appendix describes certain UK and US tax consequences for Scheme Creditors and Bondholders of implementation of the Schemes and of holding the Scheme Consideration. Discussion of the UK tax consequences can be found in Part A of this Appendix, and discussion of the US tax consequences in Part B. It will be noted that there are significant differences between the tax consequences for Scheme Creditors and Bondholders in the UK and the US, which result from the differences in the underlying tax systems. The discussion of the tax consequences in the UK and US does not purport to be comprehensive, and the tax consequences of the proposals in other jurisdictions are not discussed. Scheme Creditors and Bondholders considering the Restructuring are therefore encouraged to consult their own tax advisers concerning the tax consequences of the proposals for them in the light of their particular circumstances. PART A -- UK TAXATION The following summary describes certain UK tax consequences for Scheme Creditors and Bondholders of the implementation of the Schemes and of ownership of the New Shares and the New Notes, but does not purport to be comprehensive. Except where noted, it relates only to the position of persons who hold the Scheme Claims, New Shares and New Notes as investments and who are the absolute beneficial owners of Scheme Claims, New Shares and New Notes. The statements may not apply to special situations, such as those of dealers in securities or persons connected with Corp or plc. Furthermore, the discussion below is generally based upon the provisions of UK tax law and UK Inland Revenue practice as of the date hereof, and such provisions may be repealed, revoked or modified (possibly with retrospective effect) so as to result in UK tax consequences different from those discussed below. Scheme Creditors or Bondholders considering the Restructuring should consult their own tax advisers concerning UK tax consequences in the light of their particular situations as well as any consequences arising under the law of any other relevant jurisdiction. No representations are made with respect to the tax consequences to any particular holder of Scheme Claims, New Shares or New Notes. Specifically, the comments below do not address the tax consequences in a jurisdiction other than the UK of the Restructuring or of any subsequent holding or disposal of New Shares or New Notes. Holders of Scheme Claims, New Shares or New Notes in a jurisdiction other than the UK are strongly urged to consult their professional advisers to determine their own tax position. TAX EFFECTS OF IMPLEMENTATION OF THE SCHEMES The following description assumes that the Schemes are both implemented in accordance with the Restructuring proposals but does not deal with all possible eventualities. The tax consequences of implementation of the Schemes for Scheme Creditors are not in all cases clear cut. Tax consequences for a Scheme Creditor will depend on the nature of the Scheme Creditor's Scheme Claim. The Inland Revenue has confirmed that Bondholders that are within the charge to taxation of chargeable gains will be taxed as described below. Scheme Creditors whose claims are not described in this section, or who are in any doubt about their tax position, are encouraged to consult their own tax advisers. CLAIMS IN THE CORP SCHEME The tax consequences for Corp Scheme Creditors and Bondholders receiving a distribution in the Corp Scheme may depend on whether the distribution is part of the Initial Distribution or part of any further distribution under the Scheme. Tax Treatment on Effective Date Scheme Creditors or Bondholders within the Charge to Corporation Tax a. A Scheme Creditor whose Scheme Claim represents a loan relationship and who holds the Scheme Claim as an investment or a Bondholder holding the Bonds as investments and within the charge to corporation tax will not realise a chargeable gain for the purposes of UK taxation of chargeable gains on the cancellation of the Scheme Claim or Bonds. It will, however, be charged to tax on all returns, profits or 851

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- gains and fluctuations in value of the Scheme Claim or Bonds, including those deriving from receipt of Scheme Consideration (and whether attributable to currency fluctuations or otherwise), broadly in accordance with its authorised accounting treatment. b. Bondholders within the Charge to Capital Gains Tax A Bondholder holding the Bonds as investments and within the charge to capital gains tax will be treated for tax purposes as receiving cash, New Notes, New Shares and a right to a further distribution under the Scheme, should one be made (a "Further Distribution Right"). To the extent that a Bondholder receives New Notes and New Shares, this will be treated as a "conversion of securities" and, therefore, will not be treated as a disposal of the Bondholder's Bonds. However, to the extent that a Bondholder receives cash or a Further Distribution Right, this will be treated as a part disposal of the Bondholder's Bonds on the Effective Date of the Corp Scheme. Accordingly, it will be necessary for a Bondholder to apportion his base cost between the New Notes and New Shares on the one hand and the cash and the Further Distribution Right on the other. This apportionment should be done in the ratio of the market value on the Effective Date of the New Notes and New Shares to the market value on the Effective Date of the Further Distribution Right and the amount of the cash. (This is subject to any apportionment the Bondholder makes between the Corp and plc Schemes -- see further below.) On receipt of the cash and the Further Distribution Right, a Bondholder may realise an allowable loss or a chargeable gain. The Bondholder's New Notes and New Shares will be treated as if they were acquired at the same time as the original Bonds and for the apportioned base costs. c. Scheme Creditors within the Charge to Capital Gains Tax A Scheme Creditor holding a debt as an investment which is not a qualifying corporate bond for the purposes of capital gains tax and which is within the charge to capital gains tax will be treated for tax purposes as set out above under Bondholders within the charge to Capital Gains Tax. d. Scheme Creditors with Scheme Claims which are Debts A Scheme Creditor whose Scheme Claim is in respect of a debt owed by Corp (which is not a trade debt) and whose position is not dealt with in the preceding paragraphs will realise neither a chargeable gain nor an allowable loss. The cash should be treated as satisfying the equivalent amount of the Scheme Creditor's claim. The Scheme Creditor will be treated as acquiring the New Notes, the New Shares and the Further Distribution Right for their market value on the Effective Date. In the case of a Scheme Creditor which is an original creditor against Corp (i.e. which is not a Scheme Creditor as a result of the assignment to it of the Scheme Claim or the underlying debt), any chargeable gain which might otherwise be realised on a subsequent disposal of the New Notes and/or New Shares will be reduced so as not to exceed the chargeable gain (if any) which would accrue if the Scheme Creditor had acquired the New Notes and/or New Shares for the full amount of its Scheme Claim (less any amount satisfied by cash or attributable to the Further Distribution Right). e. Scheme Creditors with Scheme Claims which are another form of Capital Asset A Scheme Creditor with a Scheme Claim which is another form of capital asset (such as a right to an indemnity) will be treated as disposing of that Scheme Claim on the Effective Date of the Corp Scheme in return for cash, New Notes, New Shares and the Further Distribution Right for the purposes of taxation on chargeable gains. The New Notes, New Shares and the Further Distribution Right will be treated as acquired at their market value on the Effective Date. Accordingly, a chargeable gain or an allowable loss may arise. f. Tax Treatment of Further Distributions A Scheme Creditor or Bondholder within the charge to corporation tax should bring any further distributions made under the Corp Scheme into account in accordance with its authorised accounting treatment. 852

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- For Scheme Creditors or Bondholders within the charge to capital gains tax, receipt of a further distribution under the Scheme will be treated as the disposal of the Further Distribution Right in consideration for the value of the assets received on the further distribution. Accordingly, a chargeable gain or an allowable loss may arise. Claiming an Allowable Loss A Scheme Creditor or Bondholder who realises a loss for the purposes of taxation on chargeable gains must give notice to an officer of the Board of the Inland Revenue quantifying the amount of that loss before it will be an allowable loss. The notice must be given within 5 years of 31 January following the year of assessment in which the Effective Date falls. FURTHER TAX ISSUES AFFECTING SCHEME CREDITORS AND BONDHOLDERS It is expected that the arrangements under which Scheme Consideration is held for the Scheme Creditors by the Escrow Trustee will constitute a bare trust (such bare trust being subject to an obligation on the Escrow Trustee -- as directed by the Supervisors on behalf of the Scheme Creditors -- to make distributions in accordance with the Schemes). This has the following potential consequences for Scheme Creditors: a. To the extent that the distributions made by the Escrow Trustee in accordance with the Schemes do not match exactly the beneficial entitlements of Scheme Creditors under the bare trust, the strict technical position may be that some Scheme Creditors have made disposals of their entitlements to other Scheme Creditors. However, these disposals are for no consideration, and the Scheme Creditor receiving the entitlement would acquire it at nil base cost. Accordingly, it is not expected that this technical analysis should affect the tax treatment outlined above. b. Where income (in the form of interest on the New Notes, or on any cash balances held by the Escrow Trustee) accrues on the Scheme Consideration held by the Escrow Trustee, this is strictly the income of the Scheme Creditor with the beneficial entitlement to it under the bare trust, and may be taxable when it arises or accrues, rather than when it is received. Taking a strict technical position, this could result in a Scheme Creditor or Bondholder being taxed on income he has not received. However, the Inland Revenue has agreed that, if it is satisfied that the Scheme Consideration is held on bare trust as outlined above, the Escrow Trustee should deduct tax at the basic rate (currently 22 per cent.) from any such income which arises on the Scheme Consideration before paying the remainder as part of a distribution. Scheme Creditors and Bondholders will receive a certificate showing the amount of tax deducted, and may be liable to pay additional amounts of tax or able to reclaim the tax already paid, depending on their circumstances. CLAIMS IN THE PLC SCHEME The tax consequences for plc Scheme Creditors should be the same as for Corp Scheme Creditors, subject to the following qualification in respect of the claims of Bondholders. The claims of Bondholders under the plc Scheme are in respect of the guarantees given by plc of Corp's obligations under the Bonds. Accordingly, there will not be a conversion of securities for Bondholders under the plc Scheme. Rather, Bondholders within the charge to capital gains tax may realise a chargeable gain in respect of the Scheme Consideration received in the plc Scheme. A Bondholder may, however, make an election to attribute some of the base cost in its Bonds to the Scheme Claim against plc. This would have the effect of reducing the amount of any chargeable gain realised (and could result in an allowable loss) on the receipt of the Scheme Consideration in the plc Scheme. The proportion of the Bondholder's base cost in its Bonds which may be attributed to the claim in the plc Scheme is A/(A + B), where A is the market value on the Effective Date of the assets received in the plc Scheme and B is the market value on the Effective Date of the assets received in the Corp Scheme. 853

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- TAXATION OF THE NEW NOTES INTEREST ON THE NEW NOTES The interest on the New Notes should be treated as interest for the purposes of both income tax and corporation tax. Payment of Interest on the New Notes Interest on the New Notes will be payable without withholding or deduction on account of UK tax provided that the New Notes are, and remain, listed on a "recognised stock exchange", as defined in section 841 of ICTA 1988. The London Stock Exchange is a recognised stock exchange. Under an Inland Revenue published practice, securities will be treated as listed on the London Stock Exchange if they are admitted to the Official List by the UKLA and admitted to trading on the London Stock Exchange. Interest on the New Notes may also be paid without withholding or deduction on account of UK tax where interest on the New Notes is paid to a person who belongs in the UK and, at the time the payment is made, Corp reasonably believes that either: a. the person beneficially entitled to the interest payment is within the charge to UK corporation tax as regards the payment of interest; or b. the payment is made to (or, in the case of section 349B(6) of ICTA 1988, the person beneficially entitled to the interest payment is) one of the classes of exempt bodies or persons set out in section 349B(3) to (6) of ICTA 1988, provided that the Inland Revenue has not given a direction (in circumstances where it has reasonable grounds to believe that it is likely that none of the conditions specified in section 349B of ICTA 1988 will be satisfied in respect of such payment of interest at the time the payment is made) that the exception is not to apply in relation to such a payment. In all other cases, an amount will be withheld from payments of interest on the New Notes on account of UK income tax, generally at the lower rate (currently 20 per cent.), and subject to any direction to the contrary by the Inland Revenue under an applicable double taxation treaty. Holders of New Notes who are individuals may wish to note that the Inland Revenue has power to obtain information (including the name and address of the beneficial owner of the interest) from any person in the UK who either pays interest to or receives interest for the benefit of an individual (whether or not the interest has been subject to deduction at source and whether or not the holder is resident in the UK for UK tax purposes). Information so obtained may, in certain circumstances, be passed on by the Inland Revenue to the tax authorities of other jurisdictions. Proposed EU Savings Directive On 21 January 2003 the European Council of Economics and Finance Ministers ("ECOFIN") provisionally agreed on proposals under which Member States will be required to provide to the tax authorities of another Member State details of payments of interest (or similar income) paid by a person within its jurisdiction to an individual resident in that other Member State, except that, for a transitional period only, Belgium, Luxembourg and Austria will instead be required to operate a withholding system in relation to such payments (the ending of such transitional period being related to the conclusion of certain other agreements relating to information exchange with certain other countries). The proposed directive may be subject to further amendment and/or clarification. Further UK Income Tax Issues Interest on the New Notes constitutes UK source income for tax purposes and, as such, may be subject to income tax by direct assessment even where paid without withholding. However, interest with a UK source received without deduction or withholding on account of UK tax will not be chargeable to UK tax in the hands of a holder of New Notes (other than certain trustees) who is not resident for 854

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- tax purposes in the UK in most cases unless that holder carries on a trade, profession or vocation in the UK through a UK branch or agency in connection with which the interest is received or to which the New Notes are attributable. There are exemptions for interest received by certain categories of agent (such as some brokers and investment managers). The provisions of an applicable double taxation treaty may also be relevant for such holders. Where the New Notes are to be, or may fall to be, redeemed at a premium or where a payment is made in respect of interest which would have accrued prior to the Issue Date, and that payment is treated as a premium, then any such element of premium may constitute a payment of interest, subject to UK taxation and reporting requirements as outlined above. Where additional New Notes are issued in lieu of payment of interest in cash, this will be treated for UK tax purposes as if it were the payment of an amount of that interest equal to the value of the additional New Notes at the time of their issue which value may not be equal to the par value of such New Notes and may therefore be different from the amount of cash interest payable. UK CORPORATION TAX PAYERS In general holders of New Notes which are within the charge to UK corporation tax in respect of those Notes (other than authorised unit trusts and open-ended investment companies) will be treated for tax purposes as realising profits or losses in respect of the New Notes on a basis which is broadly in accordance with their statutory accounting treatment so long as the accounting treatment is in accordance with a mark-to-market basis or an accruals basis which is authorised for tax purposes. Such profits and losses will be taken into account in computing taxable income for corporation tax purposes. With effect from the beginning of their first accounting period commencing on or after 1 October 2002, holders of New Notes that are authorised unit trusts or open ended investment companies will be subject to the same taxation treatment in respect of the New Notes as other holders that are within the charge to UK corporation tax, other than (in each case) with respect to profits and losses of a capital nature in respect of the New Notes. OTHER UK TAX PAYERS Taxation of Capital Gains A disposal of the New Notes by an individual holder who is resident or ordinarily resident in the United Kingdom or who carries on a trade, profession or vocation in the United Kingdom through a branch or agency to which the New Notes are attributable, may give rise to a chargeable gain or allowable loss for the purposes of UK taxation of chargeable gains. Accrued Income Scheme A holder disposing of New Notes will be chargeable to tax on income, under the rules of the accrued income scheme as set out in Chapter II of Part XVII of ICTA 1988, on any interest which has accrued since the last interest payment date on, and, to the extent it is treated as interest, any premium on redemption of the New Notes, on a just and reasonable basis, if that holder is resident or ordinarily resident in the United Kingdom or carries on a trade in the United Kingdom through a branch or agency to which the New Notes are attributable. TAXATION OF THE NEW SHARES DIVIDENDS Under current UK tax law, Corp will not be required to withhold tax at source from dividend payments it makes. UK Corporation Tax Payers A shareholder which is within the charge to UK corporation tax will not normally be subject to corporation tax on any dividend received from Corp. Such a shareholder will not be able to claim repayment of the tax credit attaching to any dividend. 855

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- Other UK Tax Payers -- Individuals An individual shareholder who is resident in the UK for tax purposes and who receives a dividend from Corp will be entitled to a tax credit which may be set off against his total income tax liability on the dividend. Such an individual shareholder's liability to income tax is calculated on the aggregate of the dividend and the tax credit (the "gross dividend") which will be regarded as the top slice of the individual's income. The tax credit will be equal to 10 per cent. of the "gross dividend" (i.e. the tax credit will be one-ninth of the amount of the dividend). Generally, a UK resident individual shareholder who is not liable to income tax in respect of the gross dividend will not be entitled to reclaim any part of the tax credit. A UK resident shareholder who is not liable to income tax at a rate in excess of the basic rate will be subject to income tax on the dividend at the rate of 10 per cent. of the gross dividend so that the tax credit will satisfy in full such shareholder's liability to income tax on the dividend. A UK resident individual shareholder liable to income tax at the higher rate will be subject to income tax on the gross dividend at 32.5 per cent. but will be able to set the tax credit off against part of this liability. The effect of the set-off of the tax credit is that such a shareholder will have to account for additional tax equal to 25 per cent. of the cash dividend received. Pension Funds UK pension funds will not be entitled to reclaim the tax credit attaching to any dividend paid by Corp. Non-residents A shareholder who is resident outside the UK will not generally be entitled to any payment from the Inland Revenue in respect of the tax credit attaching to any dividend paid by Corp, subject to the provisions of any double tax treaty between the UK and his country of residence. Persons who are not resident in the UK should consult their own professional advisers as to whether they are entitled to reclaim any part of the tax credit, the procedure for doing so and what relief or credit may be claimed in the jurisdiction in which they are resident for tax purposes in respect of such tax credit. TAXATION OF CAPITAL GAINS A disposal of the New Shares by a shareholder who is either resident or ordinarily resident in the UK for tax purposes, or is not UK resident but carries on a trade, profession or vocation in the UK through a branch or agency or, for accounting periods beginning on or after 1 January 2003, a permanent establishment and has used, held or acquired the New Shares for the purposes of such trade, profession or vocation or such branch or agency, or, as the case may be, permanent establishment may, depending on the shareholder's circumstances and subject to any available exemption or relief, give rise to a chargeable gain or an allowable loss for the purposes of the taxation of capital gains. A shareholder who is an individual normally resident or ordinarily resident in the UK and who has, on or after 17 March 1998, become neither resident nor ordinarily resident in the UK for tax purposes for a period of less than five years of assessment and who disposes of the New Shares during that period may also be liable on his return to the UK to tax on any capital gain realised (subject to any available exemption or relief). There are special rules for individuals who leave the UK part way through a year of assessment. Persons who are not resident or ordinarily resident in the UK for tax purposes will not be within the charge to UK tax on capital gains on the disposal of the New Shares unless they carry on a trade, profession or vocation in the UK through a branch or agency as described above. For individuals, taper relief may apply in relation to periods after 5 April 1998 so that the effective rate of capital gains tax on any gain on a disposal by an individual of the New Shares will be reduced the longer the New Shares are held, up to a maximum of, generally, 10 years. 856

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- STAMP DUTY AND STAMP DUTY RESERVE TAX ("SDRT") There will be no charge to UK stamp duty or SDRT in respect of cancellation of the Bonds. ISSUE AND TRANSFER OF THE NEW NOTES No stamp duty or SDRT should be payable on the issue or transfer by delivery of the New Notes. No stamp duty or SDRT should be payable by a Scheme Creditor or a Bondholder in respect of the arrangements for the distribution of New Notes under the Schemes. The transfer or sale of New Notes in definitive registered form will be liable to ad valorem stamp duty at the rate of 0.5 per cent. of the consideration paid, or the agreement to make that transfer will be liable to SDRT at the rate of 0.5 per cent of the consideration paid. The purchaser of the New Notes will generally pay the stamp duty or, as the case may be, SDRT. ISSUE OF NEW SHARES UNDER THE SCHEMES In relation to the New Shares being issued by Corp and subject to the comments below, no liability to stamp duty or SDRT will arise on the issue of, or on the issue of definitive share certificates in respect of, such shares by Corp. The New Shares are being issued into CREST. Where a Scheme Creditor or Bondholder is entitled to receive New Shares under the Schemes, there will be no charge to stamp duty or SDRT on the transfer of New Shares to the CREST account of that Scheme Creditor or Bondholder, or to the CREST account of a person holding the New Shares on his behalf. Scheme Creditors and Designated Recipients who receive New Shares in the form of ADRs pursuant to the Schemes at any time will not be required to pay any UK stamp duty or SDRT in respect of the initial issuance of such ADRs. Scheme Creditors and Designated Recipients who receive New Shares in non-ADR form pursuant to the Schemes will not be required to pay any stamp duty or SDRT in respect of the initial issuance of ADRs upon deposit of those New Shares or an equivalent number of New Shares (but not any additional Corp Shares) in exchange for ADRs, if such transfer is effected prior to the date falling two calendar months after the effectiveness of the NASDAQ listing of the ADRs and the procedures referred to in Appendix 16 in the paragraph headed "Persons electing to receive New Shares pursuant to the Schemes" are complied with. The position with regard to the issue of ADRs is discussed more fully in the paragraph headed "Clearance Services and ADRs" below. No stamp duty or SDRT should be payable by a Scheme Creditor or a Bondholder in respect of the arrangements for the distribution of New Shares under the Schemes. SUBSEQUENT TRANSFERS OF NEW SHARES Under the CREST system for paperless share transfers, deposits of New Shares into CREST will generally not be subject to stamp duty or SDRT unless such a transfer is made for a consideration in money or money's worth, in which case a liability to SDRT will arise usually at the rate of 0.5 per cent. of the value of the consideration given. Paperless transfers of New Shares within CREST are generally liable to SDRT, rather than stamp duty, at the rate of 0.5 per cent. of the amount or value of the consideration payable. CREST is obliged to collect SDRT from the purchaser of the New Shares on relevant transactions settled within the system. The conveyance or transfer on sale of the New Shares outside the CREST system will generally be subject to ad valorem stamp duty on the instrument of transfer at the rate of 0.5 per cent. of the amount or value of the consideration given. Such ad valorem stamp duty will be rounded up to the nearest L5. Stamp duty is normally the liability of the purchaser or transferee of the New Shares. An unconditional agreement to transfer New Shares will normally give rise to a charge to SDRT at the rate of 0.5 per cent. of the amount or value of the consideration for the New Shares. However, where within six years of the date of the agreement, an instrument of transfer is executed and duly stamped, the SDRT liability will be cancelled and any SDRT which has been paid will be repaid. SDRT is normally the liability of the purchaser or transferee of the New Shares. The position with regard 857

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- to the transfer of New Shares to a clearance service or to an issuer of ADRs is discussed in the paragraph headed "Clearance Services and ADRs" below. CLEARANCE SERVICES AND ADRS Where New Shares are issued or transferred (i) to, or to a nominee for, a person whose business is or includes the provision of clearance services or (ii) to, or to a nominee or agent for, a person whose business is or includes issuing depositary receipts, (for example where a Scheme Creditor elects to receive New Shares in the form of ADRs) ad valorem stamp duty (in the case of a transfer only to such persons) or SDRT may be payable at a rate of 1.5 per cent. of the amount or value of the consideration payable, or, in certain circumstances, the value of the New Shares or, in the case of an issue to such persons, the issue price of the New Shares. Ad valorem stamp duty will be rounded up to the nearest L5. Strictly the depositary or clearance operator, or its nominee, as the case may be, will be accountable for this liability for stamp duty or SDRT. However, it will in practice generally be reimbursed by participants in the clearance service or depositary receipt scheme. As noted above, special arrangements have been made in certain circumstances in relation to the payment of SDRT on the issue of New Shares in ADR form pursuant to the Schemes and the payment of stamp duty and SDRT on the issue of ADRs upon deposit of New Shares in exchange for ADRs. Clearance service providers may opt, under certain circumstances, for the normal rates of stamp duty and SDRT to apply to an issue (i.e. no stamp duty or SDRT) or transfer (i.e. 0.5 per cent.) of New Shares into, and to transactions within (i.e. 0.5 per cent.), the service instead of the higher rate applying to an issue or transfer of the New Shares into the clearance system and the exemption for dealings in the New Shares whilst in the system. The above statements are intended as a general guide to the current position. Certain categories of person, including market intermediaries, are not liable to stamp duty or SDRT and others may be liable at a higher rate or may, although not primarily liable for tax, be required to notify and account for it under the Stamp Duty Reserve Tax Regulations 1986. ANY PERSON WHO IS IN ANY DOUBT AS TO HIS TAX POSITION OR WHO MAY BE SUBJECT TO TAX IN ANY JURISDICTION OTHER THAN THE UK SHOULD CONSULT HIS PROFESSIONAL ADVISER. For further information, see "Description of American Depositary Receipts" in Appendix 16. PART B -- US FEDERAL INCOME TAXATION The following summary describes certain US federal income tax consequences that may be relevant to the acquisition, ownership and disposition of New Shares, New Senior Notes, New Junior Notes, and/or ADRs. This summary addresses only US federal income tax considerations for holders that acquire the New Shares, New Senior Notes, New Junior Notes, and/or ADRs as a result of the transactions described in this document and that hold their Scheme Claim and will hold the New Shares, New Senior Notes, New Junior Notes, and/or ADRs as capital assets. It does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to acquire New Shares, New Senior Notes, New Junior Notes, and/or ADRs. In particular, this summary does not address tax considerations applicable to holders that may be subject to special tax rules including, without limitation, the following: (a) financial institutions; (b) insurance companies; (c) dealers or traders in securities or currencies; (d) tax-exempt entities; (e) persons that will hold the New Shares, New Senior Notes, New Junior Notes, and/or ADRs as part of a "hedging" or "conversion" transaction or as a position in a "straddle" or as part of a "synthetic security" or other integrated transaction for US federal income tax purposes; (f) persons that have a "functional currency" other than the US dollar; (g) persons that own (or are deemed to own) 5 per cent. or more (by voting power or value) of Corp's stock; (h) regulated investment companies; and (i) persons who hold the New Shares, New Senior Notes, New Junior Notes, and/or ADRs through partnerships or other pass-through entities. Further, this summary does not address alternative minimum tax consequences or the indirect effects on the holders of equity interests in a holder of New Shares, New Senior Notes, New Junior Notes and/or ADRs. This summary is based on the US Internal Revenue Code of 1986, as amended (the "CODE"), US Treasury regulations and judicial and administrative interpretations thereof, and the Convention Between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern 858

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- Ireland for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital Gains signed on 31 December 1975 and entered into force on 25 April 1981 (the "Current Treaty"), in each case as in effect and available on the date of the Schemes described in these documents. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax consequences described below. The United States and United Kingdom have signed a new income tax treaty (the "New Treaty") which will enter into force only after ratification by each country and it cannot be determined when that will occur. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISER WITH RESPECT TO THE US FEDERAL, ESTATE, STATE, LOCAL, GIFT AND OTHER TAX CONSEQUENCES OF ACQUIRING, OWNING AND DISPOSING OF NEW SHARES, NEW SENIOR NOTES, NEW JUNIOR NOTES, AND/OR ADRS. US HOLDERS SHOULD ALSO REVIEW THE DISCUSSION UNDER "UK TAXATION" FOR THE UK TAX CONSEQUENCES TO A US HOLDER OF NEW SHARES, NEW SENIOR NOTES, NEW JUNIOR NOTES, AND/OR ADRS. For the purposes of this summary a "US Holder" is a beneficial owner of a Scheme Claim, New Shares, New Senior Notes, New Junior Notes, or ADRs that is, for US federal income tax purposes: (a) a citizen or resident of the US; (b) a corporation or other entity treated as a corporation for US tax purposes, created or organised in or under the laws of the US or any state thereof (including the District of Columbia); (c) an estate, the income of which is subject to US federal income taxation regardless of its source; or (d) a trust if (i) a court within the US is able to exercise primary supervision over its administration and (ii) one or more US persons have the authority to control all of the substantial decisions of such trust. If a partnership holds a Scheme Claim, New Shares, New Senior Notes, New Junior Notes, or ADRs, the consequences to a partner will generally depend upon the status of the partner and upon the activities of the partnership. A partner of a partnership holding a Scheme Claim, New Shares, New Senior Notes, New Junior Notes, or ADRs should consult its tax adviser. A "Non-US Holder" is a beneficial owner of a Scheme Claim, New Shares, New Senior Notes, New Junior Notes, or ADRs that is not a US Holder. EXCHANGE OR DISPOSAL OF SCHEME CLAIMS Consequences to plc Scheme Creditors A US Holder that is a plc Scheme Creditor should generally recognise gain or loss on the exchange of a Scheme Claim in an amount equal to the difference between the amount realised on the exchange (except to the extent such amounts are attributable to accrued but unpaid interest which will be taxable as such) and the US Holder's tax basis in the Scheme Claim. The amount realised on the exchange of a Scheme Claim will generally be the fair market value (in US dollars) of the cash, New Shares, New Senior Notes, New Junior Notes, and/or ADRs, (i) on the date such property is received in the case of a cash basis US Holder, (ii) on the date of the exchange in the case of an accrual basis US Holder, or (iii) in the case of Scheme Claims traded on an established securities market (as defined in the applicable US Treasury regulations) that are exchanged by a cash basis US Holder, or an electing accrual basis US Holder, the US dollar value on the settlement date of the exchange. Gain or loss recognised by a US Holder on the exchange of a Scheme Claim that is attributable to changes in currency exchange rates will be ordinary income or loss and will be characterised as principal exchange gain or loss. Principal exchange gain or loss will equal the difference between the US dollar value of the US Holder's purchase price of the Scheme Claim in foreign currency determined on the date of the exchange, and the US dollar value of the US Holder's purchase price of the Scheme Claim in foreign currency determined on the date the US Holder acquired the Scheme Claim. Such gain or loss will be recognised only to the extent of the total gain or loss recognised by the US Holder on the exchange of the Scheme Claim, and will generally be treated as from sources within the US for US foreign tax credit limitation purposes. Any gain or loss recognised by a US Holder in excess of principal exchange gain or loss recognised on the exchange of the Scheme Claim will generally be US source capital gain or loss. Persons considering the proposals included in these documents should consult their own tax advisers with respect to the treatment of capital gains (which may be taxed at lower rates than ordinary income for taxpayers who are individuals, trusts or estates that held Scheme Claims for more than one year) and capital losses (the deductibility of which is subject to limitations). 859

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- To the extent a US Holder's Scheme Claim includes an obligation of plc that is a "market discount" bond, any gain (other than foreign currency gain) recognised by the US Holder on the exchange of such Scheme Claim for cash, New Shares, New Senior Notes, New Junior Notes, and/ or ADRs, may be characterised as ordinary interest income to the extent of the "accrued market discount". Generally, a bond issued by plc will have "market discount" where the bond's "stated redemption price at maturity" (i.e. an amount equal to the sum of all payments provided under the bond other than "qualified stated interest payments" as described below in "New Senior Notes, and New Junior Notes -- Original Issue Discount"), exceeds a US Holder's tax basis in such bond immediately after the US Holder acquired the bond (except in general, for an acquisition of a bond at original issuance). Where a bond contains "original issue discount", then the stated redemption price at maturity shall be the sum of the bond's issue price and the aggregate amount of the original issue discount, excluding any "acquisition premium" includible in the gross income of all holders of the bond during period or periods before the US Holder acquired the bond (the "revised issue price"). The amount of "accrued market discount" is the product of the total market discount and the ratio of the number of days the US Holder has held the bond to the total number of days after the acquisition date up to, and including, the date of maturity of the bond, unless such Holder had made an irrevocable election to include such market discount in its gross income on a constant yield basis. For purposes of determining the source of the income, withholding or information reporting, any gain treated as ordinary income will not be characterised as interest. Persons considering the proposals included in these documents should consult with their own tax advisors with respect to the applicability of the market discount bond rules under the Code, including special rules where a market discount bond may contain original issue discount and/or provide for two or more principal payments, to their own individual circumstances and the appropriate US federal income tax consequences that may be applicable to them arising from the exchange of a Scheme Claim that includes a "market discount" bond for cash, New Shares, New Senior Notes, New Junior Notes and/or ADRs. All distributions to a plc Scheme Creditor as a result of the transactions described in this document will be treated as described above. A US Holder's basis in the property received should equal the fair market value of such property. Foreign currency received on the exchange of a Scheme Claim will have a tax basis equal to its US dollar value at the time the payment is received. Gain or loss, if any, recognised on the subsequent sale, conversion or disposition of such foreign currency will be ordinary income or loss, and will generally be income or loss from sources within the US for foreign tax credit limitation purposes. However, if such foreign currency is converted into US dollars on the date received by the US Holder, a cash basis or electing accrual basis US Holder should not recognise any gain or loss on such conversion. Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income or withholding tax on any gain realised on the exchange of a Scheme Claim unless: (a) that gain is effectively connected with the conduct by that Non-US Holder of a trade or business in the US, (b) in the case of any gain realised by an individual Non-US Holder, that holder is present in the US for 183 days or more in the taxable year of disposition and certain conditions are met, or (c) the Non-US Holder is subject to tax pursuant to provisions of the Code applicable to certain expatriates. A Non-US Holder generally will not be subject to US federal income or withholding tax on any amount realised on the exchange of a Scheme Claim that is attributable to accrued but unpaid interest unless that income is effectively connected with the conduct by that Non-US Holder of a trade or business within the US. Consequences to Corp Scheme Creditors The US federal income tax consequences to US Holders who are Corp Scheme Creditors depends in part on whether the New Senior Notes and New Junior Notes on the one hand, and Scheme Claims, on the other hand, are "securities". The determination of whether a debt instrument constitutes a security for US federal income tax purposes depends on its terms and conditions, and upon other facts and circumstances. Due to the inherently factual nature of whether a debt instrument is a security for US federal income tax purposes, the US Internal Revenue Service (the "IRS") or a court could determine that the New Senior Notes, New Junior Notes, and Scheme Claims do not constitute securities. In such case the tax consequences to a US Holder would be as set 860

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- forth above under "Consequences to plc Scheme Creditors". The remainder of this discussion assumes that the New Senior Notes, New Junior Notes, and Scheme Claims are securities for US federal income tax purposes. A US Holder should generally not recognise gain or loss on the exchange of a Scheme Claim for New Shares, New Senior Notes, New Junior Notes, and/or ADRs, (i.e., securities received in the exchange except to the extent such securities are attributable to accrued but unpaid interest which will be taxable as such) ("Nonrecognition Exchange"). A US Holder should recognise gain, but not loss, to the extent of cash and the principal amount of securities received in excess of the principal amount of securities surrendered (such cash and excess principal amount being referred to as "Other Property") less any amounts attributable to accrued but unpaid interest which will be taxable as such. Such gain may be characterised as a dividend to the extent of the US Holder's ratable share of Corp's undistributed earnings and profits (as determined for US federal income tax purposes). PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS WITH RESPECT TO THE CHARACTERISATION OF GAIN ON THE EXCHANGE. The amount recognised on the exchange of a Scheme Claim for cash, New Shares, New Senior Notes, New Junior Notes, and/or ADRs, should be the difference between (a) the US dollar value of such cash, New Shares, New Senior Notes, New Junior Notes, and/or ADRs, (i) on the date the property is received in the case of a cash basis US Holder, (ii) on the date of the exchange in the case of an accrual basis US Holder, or (iii) in the case of Scheme Claims traded on an established securities market (as defined in the applicable US Treasury regulations) that are exchanged by a cash basis US Holder, or an electing accrual basis US Holder, the US dollar value on the settlement date of the exchange, and (b) the US Holder's tax basis in the Scheme Claim; provided, however, if the fair market value of the Other Property is less than the total gain recognised under the foregoing formula than the gain recognised will be the fair market value of the Other Property. A US Holder's basis in the securities received should equal such US Holder's basis in the Scheme Claim exchanged therefor, decreased by the amount of Other Property received (excluding Other Property attributable to accrued but unpaid interest) and increased by the amount of gain recognised on the exchange. Gain recognised by a US Holder on the exchange of a Scheme Claim that is attributable to changes in currency exchange rates will be ordinary and will be characterised as principal exchange gain. Principal exchange gain will equal the difference between the US dollar value of the US Holder's purchase price of the Scheme Claim in foreign currency determined on the date of the exchange, and the US dollar value of the US Holder's purchase price of the Scheme Claim in foreign currency determined on the date the US Holder acquired the Scheme Claim. Such gain will be recognised only to the extent of the total gain recognised by the US Holder on the exchange of the Scheme Claim, and will generally be treated as from sources within the US for US foreign tax credit limitation purposes. Any gain recognised by a US Holder in excess of principal exchange gain recognised on the exchange of the Scheme Claim would generally be US source capital gain (except to the extent such amounts are attributable to accrued but unpaid interest which will be taxable as such). PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS WITH RESPECT TO THE TREATMENT OF CAPITAL GAINS (WHICH MAY BE TAXED AT LOWER RATES THAN ORDINARY INCOME FOR TAXPAYERS WHO ARE INDIVIDUALS, TRUSTS OR ESTATES THAT HELD THE SCHEME CLAIMS FOR MORE THAN ONE YEAR). To the extent a US Holder's Scheme Claim includes an obligation of Corp that is a market discount bond, as described in "Consequences to plc Scheme Creditors" above, and the US Holder's basis in the securities received is determined in part by the basis of such Holder's Scheme Claim, any gain (other than foreign currency gain) recognised on the exchange of the Scheme Claim for cash, New Shares, New Junior Notes and/or ADRs may be recharacterised as ordinary income to the extent of "accrued market discount", if any, on such market discount bond. Depending upon the individual circumstances of each US Holder exchanging a market discount bond of Corp, any additional amount of accrued market discount not recognised as ordinary income on the exchange would be treated as (i) accrued market discount with respect to any market discount bond received in the exchange, if any; (ii) original issue discount with respect to any New Senior Notes and/or New Junior Notes received to the extent such notes do not have any market discount; and (iii) ordinary income upon the sale, exchange or disposition of any New Shares and/or ADRs received. Any accrued market discount on a market discount bond, if any, may be accrued on a ratable basis or accrued and recognised on a constant yield basis as described in "Consequences to plc Scheme Creditors" above. Any original issue discount on the New Senior 861

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- Notes and/or New Junior Notes received by a US Holder in the Nonrecognition Exchange that is attributed to any accrued market discount from a market discount obligation of Corp will be accounted for as discussed below under "New Senior Notes, and New Junior Notes -- Original Issue Discount". The basis of any New Senior Notes and/or New Junior Notes shall be increased by the amount of ordinary income attributable to accrued market discount recognised under the market discount rules. Persons considering the proposals included in these documents should consult their own tax advisers regarding the applicability of the market discount rules under the Code, including special rules regarding the exchange of a market discount bond in a Nonrecognition Exchange, to each of their own individual circumstances and the appropriate US federal income tax treatment that may be applicable with respect to each US Holder arising from the exchange of a Scheme Claim that includes a market discount bond for cash, New Shares, New Senior Notes, New Junior Notes and/or ADRs. Foreign currency received on the exchange of a Scheme Claim will have a tax basis equal to its US dollar value at the time the payment is received. Gain or loss, if any, recognised on the subsequent sale, conversion or disposition of such foreign currency will be ordinary income or loss, and will generally be income or loss from sources within the US for foreign tax credit limitation purposes. However, if such foreign currency is converted into US dollars on the date received by the US Holder, a cash basis or electing accrual basis US Holder should not recognise any gain or loss on such conversion. Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income or withholding tax on any gain realised on the exchange of a Scheme Claim unless: (a) that gain is effectively connected with the conduct by that Non-US Holder of a trade or business in the US, (b) in the case of any gain realised by an individual Non-US Holder, that holder is present in the US for 183 days or more in the taxable year of disposition and certain conditions are met, or (c) the Non-US Holder is subject to tax pursuant to provisions of the Code applicable to certain expatriates. A Non-US Holder generally will not be subject to US federal income or withholding tax on any amount realised on the exchange of a Scheme Claim that is attributable to accrued but unpaid interest unless that income is effectively connected with the conduct by that Non-US Holder of a trade or business within the US. NEW SENIOR NOTES, AND NEW JUNIOR NOTES The New Senior Notes will, and the New Junior Notes should, be treated as indebtedness for US federal income tax purposes. In the unlikely event the New Junior Notes are treated as equity, their US tax consequences would be generally as described below at "The New Shares and ADRs". The remainder of this discussion assumes that the New Junior Notes will constitute indebtedness for US federal income tax purposes. Treatment of Interest Attributable to the Period Prior to the Issuance of the New Senior Notes and New Junior Notes This section addresses the treatment of amounts paid on the New Senior Notes and New Junior Notes that represent interest attributable to the period prior to the issuance thereof, i.e., 1 May 2003 until the date on which the New Senior Notes and New Junior Notes are issued. The US federal income tax treatment of such amounts is not entirely clear. It is possible that such amounts would be treated as additional cash consideration received in exchange for a US Holder's Scheme Claim. Such additional cash would either increase a US Holder's recognised gain or reduce such US Holder's tax basis in the New Senior Notes and/or New Junior Notes. Alternatively, in the case of Senior Notes such amounts may be treated as amortisable bond premium subject to the discussion below under "Bond Premium". PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE PROPER TREATMENT OF AMOUNTS PAID ON THE NEW SENIOR NOTES AND NEW JUNIOR NOTES THAT REPRESENT INTEREST ATTRIBUTABLE TO PERIODS PRIOR TO THE ISSUANCE THEREOF. Payment of Interest on New Junior Notes Corp may pay interest on the New Junior Notes in cash. If Corp does not pay interest in cash, interest on the New Junior Notes may be paid by issuing additional New Junior Notes in a principal amount equal to the amount of interest payable (referred to for purposes of the following discussion as the "Additional Notes"). 862

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- Because the terms of the New Junior Notes issued on the original issue date (the "Original Notes") provide that US Holders may receive Additional Notes of Corp in lieu of actual cash interest payments, certain provisions of the Treasury regulations relating to "original issue discount" ("OID") instruments (the "OID Regulations" as described below under "Original Issue Discount") require that any Additional Notes issued be aggregated with the Original Notes in order to determine the yield on the Original Notes and Additional Notes. As a result, the issue of Additional Notes is not considered to be a cash payment made on the Original Notes and OID accruals are determined as if all payments on the New Junior Notes were deferred until maturity. Accordingly, for purposes of this discussion, the Original Notes and the Additional Notes shall, unless otherwise indicated, be referred to collectively as the "New Junior Notes". With respect to the option to pay interest in cash or in Additional Notes (as just described), the US Treasury regulations assume for US federal income tax purposes that Corp will choose the option that would minimise the yield on the Original Notes. Should Corp choose the payment option that is contrary to the one assumed in accordance with the Treasury regulations, the US Holder must make a subsequent adjustment. If cash payment is assumed and Corp issues Additional Notes, then the New Junior Notes will be treated as retired and then reissued for an amount equal to the "adjusted issue price" of the New Junior Notes. The "adjusted issue price" ("AIP") of a debt instrument at the beginning of an accrual period is defined generally as the issue price of the debt instrument plus the aggregate amount of OID that accrued in all prior accrual periods less any amounts paid on the debt instruments in all prior accrual periods (other than "qualified stated interest", as described below at "Original Issue Discount"). If Additional Notes payment option is assumed and Corp subsequently makes cash interest payments (which for this purpose shall include any additional amounts payable and any UK tax withheld), such cash payments will be treated as "pro rata prepayments" (as defined in the OID Regulations) resulting in a deemed retirement of a portion of the New Junior Notes and capital gain or loss. The amount of gain or loss realised would be equal to the difference between the US dollar value of the cash payment and the tax basis of the portion of the New Junior Notes deemed retired. See also the discussion of foreign currency gain or loss under "New Senior Notes and New Junior Notes -- Sale, Exchange or Retirement". Under such circumstances, the AIP and adjusted basis of the New Junior Notes would be reduced by an amount equal to the basis of the portion of the New Junior Notes deemed retired. It is anticipated that payment of interest in cash would minimise the yield on the Original Notes, and is therefore the option Corp will be assumed to choose for purposes of the US Treasury regulation. The remainder of this disclosure presumes this to be the case. ALTHOUGH THERE ARE NO AUTHORITIES DIRECTLY ADDRESSING SIMILAR TRANSACTIONS INVOLVING NOTES ISSUED BY AN ENTITY WITH TERMS SIMILAR TO THOSE OF THE NEW JUNIOR NOTES, CORP BELIEVES THAT THE NEW JUNIOR NOTES SHOULD LIKELY BE SUBJECT TO THE SPECIAL OID REGULATIONS RELATING TO THE OPTION OF PAYING INTEREST "IN-KIND", AS DESCRIBED ABOVE. HOWEVER, THE IRS'S TREATMENT OF THE NEW JUNIOR NOTES COULD DIFFER FROM THE TREATMENT DESCRIBED ABOVE. TO THE EXTENT THE OID REGULATIONS RELATING TO THE OPTIONS OF PAYING INTEREST "IN-KIND" DO NOT APPLY, THE NEW JUNIOR NOTES WOULD BE CONSIDERED CONTINGENT PAYMENT DEBT INSTRUMENTS AND WOULD BE SUBJECT TO THE TREASURY REGULATIONS DESCRIBED IN THE "CONTINGENT PAYMENT NOTES" DISCUSSION BELOW. THE APPLICATION OF THE OID REGULATIONS, INCLUDING THE CONTINGENT PAYMENT DEBT INSTRUMENT REGULATIONS, TO DEBT INSTRUMENTS SUCH AS THE NEW JUNIOR NOTES THAT PROVIDE FOR THE OPTION OF PAYING INTEREST "IN-KIND" ARE COMPLEX AND US HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISERS WITH RESPECT TO THE PROPER APPLICATION OF THE OID REGULATIONS OR THE CONTINGENT PAYMENT DEBT INSTRUMENT REGULATIONS TO THE NEW JUNIOR NOTES. Contingent Payment Notes As discussed under "New Senior Notes and New Junior Notes -- (i) Payment of Interests with Junior PIK Notes", above, if the New Junior Notes are not treated as subject to the OID Regulations relating to the option of paying interest "in-kind", then such Notes will be treated as contingent payment debt instruments under applicable Treasury regulations. In general, regulations dealing with contingent payment debt instruments (the "CPDI Regulations") may cause the timing and character of income, gain or loss reported on a contingent payment debt instrument to differ substantially from the timing and character of income, gain or loss reported on a contingent payment debt instrument under general principles of current US federal income tax law. The CPDI Regulations generally 863

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- require a US Holder of such an instrument to include future contingent and noncontingent interest payments in income as such interest accrues based on a projected payment schedule (the "noncontingent bond method"). Moreover, in general, under the CPDI Regulations, all or a portion of gain recognised by a US Holder on the sale, exchange or retirement of a contingent payment debt instrument will be treated as ordinary income and all or a portion of any loss realised could be treated as ordinary loss as opposed to capital loss (depending on the circumstances). Under the noncontingent bond method, for each accrual period prior to and including the maturity date of the New Junior Note, the amount of interest that accrues, as OID, equals the product of (i) the adjusted issue price at the beginning of the accrual period and (ii) the "comparable yield" (adjusted for the length of the accrual period). This amount is rateably allocated to each day in the accrual period and is includible as ordinary interest income by a US Holder for each day in the accrual period on which the US Holder holds the New Junior Note. The adjusted issue price for purposes of the noncontingent bond method is equal to the New Junior Note's issue price (as set forth below under "Original Issue Discount"), increased by the interest previously accrued on the New Junior Note and decreased by the amount of any "projected payments" (as defined below) and any noncontingent payments previously made on the New Junior Note. The "comparable yield" is the annual yield that Corp would pay, as of the issue date, on a fixed rate debt instrument with no contingent payment but with terms and conditions otherwise comparable to those of the New Junior Notes, including the level of subordination, term, timing of payments and general market conditions. Amounts treated as interest under the foregoing contingent payment debt rules are treated as OID for all US federal income tax purposes. Under the noncontingent bond method, Corp is required, solely for US federal income tax purposes, to provide a schedule (the "Schedule") of the projected amounts of payments (which shall not include qualified stated interest, if any) (the "Projected Payments") on the New Junior Notes. The Schedule must produce the comparable yield. Corp's Schedule must be used to determine the US Holder's contingent payment accruals and adjustments, unless Corp does not create a Schedule or the US Holder determines that the Corp's Schedule is unreasonable, in which case the US Holder must disclose its own schedule with its US federal income tax return filings and the reason why it is not using the Corp's Schedule. Corp does not anticipate, however, that it will be providing a Schedule. If during any taxable year the sum of any actual payments (including the fair market value of any property received in that year) with respect to the New Junior Note for that taxable year (including, in the case of the taxable year which includes the maturity date of the New Junior Note, the amount of cash received at maturity) exceeds the total amount of Projected Payments for that taxable year, the difference will produce a "net positive adjustment", which will be treated as additional interest for the taxable year. If the actual amount received in a taxable year is less than the amount of the Projected Payments for that taxable year, the difference will produce a "net negative adjustment", which will (i) reduce the US Holder's interest income for that taxable year, and (ii) to the extent of any excess after the application of (i), give rise to an ordinary loss to the extent of the US Holder's interest income on the New Junior Note during the prior taxable years (reduced to the extent such interest was offset by prior net negative adjustments). If a New Junior Note is classified as a contingent payment debt instrument subject to the noncontingent bond method, any gain or loss realised on the sale or exchange of a New Junior Note may be treated as ordinary income or loss, in whole or in part. A US Holder's basis in a contingent payment debt instrument is increased by the portion of the Projected Payments accrued by the US Holder under the relevant Schedule and determined without regard to adjustments made to reflect differences between actual and Projected Payments and reduced by the amount of any noncontingent payments and the Projected Payments previously made on the New Junior Note. Where a US Holder's basis in the New Junior Note is greater than the adjusted issue price, the difference is allocated to a Projected Payment and is treated as a negative adjustment on the date the Projected Payment is made. On the date of the adjustment, the US Holder's basis is reduced by the amount of the negative adjustment. The bond premium amortisation rules under the Code do not apply to debt instruments governed by the CDPI Regulations. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS REGARDING THE POSSIBLE APPLICABILITY AND CONSEQUENCES OF THE CONTINGENT PAYMENT DEBT INSTRUMENT RULES TO THE NEW JUNIOR NOTES. 864

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- Payment of Interest on New Senior Notes Interest (including any additional amounts payable and any UK tax withheld) paid on a New Senior Note will be taxable to a US Holder as ordinary interest income at the time it is received or accrued, depending on the US Holder's method of accounting for US federal income tax purposes. A US Holder utilising the cash method of accounting for US federal income tax purposes that receives an interest payment denominated in foreign currency will be required to include in income the US dollar value of that interest payment, based on the exchange rate in effect on the date of receipt, regardless of whether the payment is in fact converted into US dollars. An accrual basis US Holder is required to include in income the US dollar value of the amount of interest accrued on a New Senior Note during the accrual period. An accrual basis US Holder may determine the amount of the interest to be recognised in accordance with either of two methods. Under the first accrual method, the amount of interest accrued will be based on the average exchange rate in effect during the interest accrual period or, with respect to an interest accrual period that spans two taxable years, the part of the period within each taxable year. Under the second accrual method, the US Holder may elect to determine the amount of interest accrued on the basis of the exchange rate in effect on the last day of the accrual period or, in the case of an accrual period that spans two taxable years, the exchange rate in effect on the last day of the part of the period within each taxable year. If the last day of the accrual period is within five Business Days of the date the interest payment is actually received, an electing accrual basis US Holder may instead translate that interest payment at the exchange rate in effect on the day of actual receipt. Any election to use the second accrual method will apply to all debt instruments held by the US Holder at the beginning of the first taxable year to which the election applies or thereafter acquired by the US Holder and will be irrevocable without the consent of the IRS. A US Holder utilising either of the foregoing two accrual methods will generally recognise ordinary income or loss with respect to accrued interest income on the date of receipt of the interest payment (including a payment attributable to accrued but unpaid interest upon the sale or retirement of a New Senior Note). The amount of ordinary income or loss will equal the difference between the US dollar value of the interest payment received (determined on the date the payment is received) in respect of the accrual period and the US dollar value of interest income that has accrued during that accrual period (as determined under the accrual method utilised by the US Holder). Foreign currency received as interest on a New Senior Note will have a tax basis equal to its US dollar value on the date the interest payment is received. Gain or loss, if any, realised by a US Holder on a sale or other disposition of the foreign currency will be ordinary income or loss and will generally be income from sources within the US for foreign tax credit limitation purposes. Interest received by a US Holder will be treated as foreign source income for the purposes of calculating that holder's foreign tax credit limitation. The limitation on foreign taxes eligible for the US foreign tax credit is calculated separately with respect to specific classes of income. For this purpose, interest on a New Senior Note should generally constitute "passive income," or in the case of certain US Holders, "financial services income." If UK tax is withheld from payments of interest, a US Holder may be entitled to a deduction or credit for such withholding tax subject to applicable limitations. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS ARE URGED TO CONSULT THEIR TAX ADVISERS REGARDING THE AVAILABILITY OF THE FOREIGN TAX CREDIT UNDER THEIR PARTICULAR CIRCUMSTANCES. Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income or withholding tax on interest received on a New Senior Note unless that income is effectively connected with the conduct by that Non-US Holder of a trade or business within the US. Original Issue Discount Subject to discussion under "Exchange or Disposal of Scheme Claims -- Consequences to Corp Scheme Creditors", the New Senior Notes will not be treated as issued with OID for US federal income tax purposes provided that the fair market value of the New Senior Notes on the date of the exchange is equal to their face amount. If the fair market value of the New Senior Notes on the date of the exchange is less than their face amount, such amount will be OID that must be taken into account as described below. The balance of this 865

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- discussion assumes that the New Senior Notes will not be treated as issued with OID for US federal income tax purposes. The New Junior Notes will be treated as issued with OID for US federal income tax purposes. The amount of the OID, will equal the excess of the "stated redemption price at maturity" (i.e. an amount equal to the sum of all payments provided under the New Junior Notes (other than "qualified stated interest payments")), over the "issue price" of the New Junior Notes. "Qualified stated interest" is generally interest paid that is unconditionally payable at least annually at a single fixed rate. The "issue price" of a New Junior Note is the fair market value of the New Junior Notes on the date of the exchange. Should Additional Notes be issued, the Additional Notes will not be considered to be a cash payment made on the Original Notes, and under the OID Regulations the stated redemption price at maturity of a New Junior Note will include all stated interest and principal payments to be made in respect thereof (whether made on an Original Note or Additional Note). Consequently, all interest payments to be received by a US Holder in respect of the New Junior Notes that are paid in Additional Notes will increase the amount of OID that must be included in income on a constant yield basis. See "Payment of Interest on New Junior Notes" above for additional discussion regarding Additional Notes and OID. A US Holder will be required to include OID on a New Junior Note in income (as ordinary income) as it accrues, calculated on a constant-yield to maturity method, before the actual receipt of cash attributable to that income, regardless of the US Holder's method of accounting for US federal income tax purposes. Generally, the amount of OID required to be included in an interest accrual period is equal to the AIP at the beginning of the accrual period times the calculated yield to maturity of the New Junior Note. Under this method, US Holders generally will be required to include in income increasingly greater amounts of OID over the life of the New Junior Note. Payments of cash interest on a New Junior Note will not be separately included in a US Holder's income, but instead will be treated first as a payment of OID accrued as of the date payment is due and not allocated to prior payments and second as a payment of principal. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS TO DETERMINE THE US FEDERAL INCOME TAX IMPLICATIONS OF THE CONSTANT-YIELD METHOD AND REGARDING THE ACCRUAL OF OID GENERALLY. OID on a New Junior Note denominated in foreign currency for any accrual period will be determined in foreign currency and then translated into US dollars in the same manner as interest payments accrued by an accrual basis US Holder, as described under "Payments of Interest on New Senior Notes" above. Upon receipt of an amount attributable to OID in these circumstances, a US Holder may recognise ordinary income or loss. OID on a New Junior Note will be treated as foreign source income for the purposes of calculating a US Holder's foreign tax credit limitation. The limitation on foreign taxes eligible for the US foreign tax credit is calculated separately with respect to specific classes of income. For this purpose, OID on a New Junior Note should generally constitute "passive income" or, in the case of certain US Holders, "financial services income." Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income tax on OID on a New Junior Note unless that income is effectively connected with the conduct by that Non-US Holder of a trade or business within the US. A US Holder will have acquisition premium with respect to New Senior Notes and New Junior Notes to the extent such US Holder's adjusted tax basis, determined on the date of the exchange (as discussed above under "Exchange or Disposal of Scheme Claims"), exceeds the issue price of the New Senior Notes and New Junior Notes. If a US Holder has acquisition premium with respect to a New Senior Note or New Junior Note, the amount includible in each taxable year as OID will be reduced by that portion of the acquisition premium properly allocable to such year or, alternatively, a US Holder may elect to treat its tax basis as the issue price of such New Senior Notes and New Junior Notes. Bond Premium The New Senior Notes and New Junior Notes will have bond premium if their fair market values on the date of the exchange exceeds their stated redemption price at maturity. A US Holder may elect to amortise any bond premium over the life of the New Senior Notes and New Junior Notes, as applicable, as an offset to interest income. The amortisation will be made using a constant yield method. If a US Holder makes the premium amortisation election, it generally applies to all debt instruments held by that US Holder at the time of the 866

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- election and any subsequently acquired debt instruments other than tax-exempt debt instruments. Once the election to amortise bond premium is made, it can not be revoked without the consent of the IRS. US Holders electing to amortise bond premium must reduce their tax basis in the affected New Senior Notes or New Junior Notes by the amount of premium amortised during their holding period for such New Senior Notes or New Junior Notes. The bond premium amortisation rules do not apply to any note that may be treated as a contingent payment debt instrument (as described above). Sale, Exchange or Retirement A US Holder's tax basis in a New Senior Note or New Junior Note will be as set forth above under "Exchange or Disposal of Scheme Claims" and "Contingent Payment Notes", increased by the amount of any OID included in the US Holder's income with respect to the New Senior Note or New Junior Note and reduced by the amount of any payments received by the US Holder with respect to the New Senior Note or New Junior Note that are not qualified stated interest payments. Although there is no authority directly on point, a US Holder that sells one or more Additional Notes (without also selling the related Original Note) would likely determine its tax basis in the Additional Notes by proportionately allocating the total tax basis held in the Original Note among the Additional Notes and the Original Note in accordance with their respective fair market values. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS WITH RESPECT TO THE ALLOCATION OF TAX BASIS AMONG THE ADDITIONAL NOTES AND THE ORIGINAL NOTE. A US Holder will generally recognise gain or loss, on the sale, exchange or retirement of a New Senior Note or New Junior Note in a manner similar to that described above under "Consequences to plc Scheme Creditors". Gain or loss recognised by a US Holder on the sale, exchange or retirement of a New Senior Note that is attributable to changes in currency exchange rates will be ordinary income or loss and will be characterised as principal exchange gain or loss. Gain or loss recognised by a US Holder on the sale, exchange or retirement of a New Junior Note that is attributable to changes in currency exchange rates will be ordinary income or loss and will be characterised as OID exchange gain or loss and principal exchange gain or loss. OID exchange gain or loss will equal the difference between the US dollar value of the amount received on the sale, exchange or retirement of a New Junior Note that is attributable to accrued but unpaid OID as determined by using the exchange rate on the date of sale, exchange or retirement and the US dollar value of the accrued but unpaid OID as determined by the US Holder under the rules described above under "Original Issue Discount". Principal exchange gain or loss will equal the difference between the US dollar value of the US Holder's acquisition price of the New Senior Note or New Junior Note in foreign currency determined on the date of the sale, exchange or retirement, and the US dollar value of the US Holder's acquisition price of the New Senior Note or New Junior Note in foreign currency determined on the date the US Holder acquired the New Senior Note or New Junior Note. Such gain or loss will be recognised only to the extent of the total gain or loss recognised by the US Holder on the sale, exchange or retirement of the New Senior Note or New Junior Note, and will generally be treated as from sources within the United States for US foreign tax credit limitation purposes. Any gain or loss recognised by a US Holder on the sale, exchange or retirement of the New Senior Note or New Junior Note in excess of principal exchange gain or loss, in the case of a New Senior Note, and principal exchange gain or loss and OID exchange gain or loss, in the case of a New Junior Note, will generally be US source capital gain or loss (except to the extent such amounts are attributable to accrued but unpaid interest which will be taxable as such). PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISERS WITH RESPECT TO THE TREATMENT OF CAPITAL GAINS (WHICH MAY BE TAXED AT LOWER RATES THAN ORDINARY INCOME FOR TAXPAYERS WHO ARE INDIVIDUALS, TRUSTS OR ESTATES THAT HOLD NEW SENIOR NOTES OR NEW JUNIOR NOTES FOR MORE THAN ONE YEAR) AND CAPITAL LOSSES (THE DEDUCTIBILITY OF WHICH IS SUBJECT TO LIMITATIONS). To the extent the New Senior Notes and/or New Junior Notes have accrued market discount as discussed above in "Exchange or Disposal of Scheme Claims -- Consequences to Corp Scheme Creditors", any gain arising from the sale, exchange or retirement of a New Senior Note and/or New Junior Note may be recognised as ordinary income to the extent of such accrued market discount. Persons considering the proposals included in these documents should consult their own tax advisors regarding the applicability of the market discount rules under the Code to each of their own individual circumstances and the US federal income tax consequences 867

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- relating to the sale, exchange or retirement of New Senior Notes and/or New Junior Notes having accrued market discount. Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income or withholding tax on any gain realised on the exchange or other disposition of a New Senior Note or New Junior Note unless: (a) that gain is effectively connected with the conduct by that Non-US Holder of a trade or business in the US, (b) in the case of any gain realised by an individual Non-US Holder, that holder is present in the US for 183 days or more in the taxable year of disposition and certain conditions are met, or (c) the Non-US Holder is subject to tax pursuant to provisions of the Code applicable to certain expatriates. THE NEW SHARES AND ADRS The US Treasury Department has expressed concern that depositaries for depositary receipts, or other intermediaries between the holders of shares of an issuer and the issuer, may be taking actions that are inconsistent with the claiming of US foreign tax credits by US Holders of such receipts or shares. Accordingly, the analysis regarding the availability of a US foreign tax credit for UK taxes and sourcing rules described below could be affected by future actions taken by the US Treasury Department. Distributions Subject to the discussion under "Passive Foreign Investment Company Considerations", the gross amount of any distributions of cash or property (including any amounts withheld in respect of any applicable withholding tax and the Tax Credit Amount (as described below)) that are actually or constructively received by a US Holder with respect to New Shares and/or ADRs will be a dividend includible in gross income of a US Holder as ordinary income to the extent of Corp's current and accumulated earnings and profits as determined under US federal income tax principles. Dividends paid on New Shares and/or ADRs generally will constitute income from sources outside the US and will not be eligible for the "dividends received" deduction. A distribution to a US Holder in excess of Corp's current and accumulated earnings and profits will be treated first as a non-taxable return of capital to the extent of such US Holder's adjusted tax basis in its New Shares or ADRs, and any distribution in excess of such basis will constitute capital gain from the sale or exchange of property, and will be long-term capital gain (taxable at a reduced rate for individual holders, trusts or estates) if the New Shares or ADRs were held for more than one year. A further reduced tax rate may apply to capital gains on New Shares and/or ADRs held by individual holders for more than five years. Corp does not maintain its calculations of its earnings and profits under US federal income tax principles. Therefore, a US Holder should expect that a distribution will generally be treated as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above. The amount of any distribution of property other than cash will be the fair market value of the property on the date of the distribution. The gross amount of any distribution paid in foreign currency will be included in the gross income of a US Holder in an amount equal to the US dollar value of the foreign currency calculated by reference to the exchange rate in effect on the date received by the US Holder, regardless of whether the foreign currency is converted into US dollars. If the foreign currency is converted into US dollars on the date of receipt, a US Holder generally should not be required to recognise foreign currency gain or loss in respect of the dividend. If the foreign currency received as a dividend is not converted into US dollars on the date of receipt, a US Holder will have a basis in the foreign currency equal to its US dollar value on the date of receipt. Any gain or loss on a subsequent conversion or other disposition of the foreign currency will be treated as ordinary income or loss, and will generally be income or loss from sources within the US for foreign tax credit limitation purposes. A US Holder that is a US resident for the purposes of the Current Treaty and that receives a dividend on New Shares and/or ADRs generally is entitled to receive a payment from the UK Inland Revenue equal to the amount of the tax credit that a UK individual would be eligible to receive with respect to an identical dividend (the "Tax Credit Amount"), subject to a reduction for UK withholding taxes of up to a maximum of 15 per cent. of the sum of the dividend and Tax Credit Amount ("UK Withholding Tax"). As of 6 April 1999, the Tax Credit Amount is 868

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- equal to one-ninth of the cash dividend paid on the New Shares and/or ADRs and the UK Withholding Tax will exactly equal the Tax Credit Amount. As a result, and because of the UK Withholding Tax and Tax Credit Amount offset, US Holders will not receive any net payment under the Current Treaty. A US Holder that receives a dividend on New Shares and/or ADRs may elect to include the Tax Credit Amount as an additional distribution by filing an election on IRS Form 8833 with the US Holder's US federal income tax return for the relevant year. If a US Holder makes the election, the US Holder will be subject to US taxation on the sum of the dividend and the Tax Credit Amount. A US Holder will also, in such a case, be treated as paying UK Withholding Tax equal to the Tax Credit Amount that, subject to generally applicable limitations, is eligible for credit against such US Holder's US federal income tax liability or, at the US Holder's election, may be deducted in computing taxable income. Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions in securities or in respect of arrangements in which a US Holder's expected economic profit, after non-US taxes, is insubstantial. The New Treaty, however, does not provide for payment of the Tax Credit Amount (except during the first year after the New Treaty comes into force). For purposes of calculating the foreign tax credit, dividends paid on New Shares and/or ADRs will be treated as income from sources outside the US and will generally constitute "passive income" or, in the case of certain US Holders, "financial services income." In certain circumstances, a US Holder that (i) has held New Shares and/or ADRs for less than a specified minimum period during which it is not protected from risk of loss or (ii) is obliged to make payments related to the dividends, will not be allowed a foreign tax credit for UK Withholding Taxes imposed on dividends paid on New Shares and/or ADRs. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS ARE URGED TO CONSULT THEIR TAX ADVISERS REGARDING THE AVAILABILITY OF THE FOREIGN TAX CREDIT UNDER THEIR PARTICULAR CIRCUMSTANCES. Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income or withholding tax on dividends received on New Shares and/or ADRs unless that income is effectively connected with the conduct by that Non-US Holder of a trade or business within the US. However, as discussed in the "Dividend Policy" discussion above, Corp does not expect to pay a dividend in the forseeable future. Sale or Other Disposition of New Shares and/or ADRs Subject to the discussion under "Passive Foreign Investment Company Considerations", a US Holder will generally recognise a gain or loss for US federal income tax purposes upon the sale or exchange of New Shares and/or ADRs in an amount equal to the difference between the US dollar value of the amount realised from such sale or exchange and the US Holder's tax basis in such New Shares and/or ADRs. Such gain or loss will be a capital gain or loss and will be long-term capital gain (taxable at a reduced rate for individuals, trusts or estates) if the New Shares and/or ADRs were held for more than one year. A further reduced tax rate may apply to capital gain on New Shares and/or ADRs held by individual holders for more than five years. Any such gain or loss would generally be treated as from sources within the US. The deductibility of capital losses is subject to significant limitations. To the extent US Holders receive the New Shares and/or ADRs pursuant to an exchange described above in "Exchange or Disposal of Scheme Claims -- Consequences to Corp Scheme Creditors", any gain arising from the sale or other disposition of the New Shares and/or ADRs may be characterised as ordinary income to the extent of any accrued market discount attributable to such New Shares and/or ADRs. Persons considering the proposals included in these documents should consult their own tax advisors regarding the applicability of the market discount rules under the Code to each of their own individual circumstances and the US federal income tax consequences relating to the sale or other disposition of the New Shares and/or ADRs with accrued market discount. A US Holder that receives foreign currency on the sale or other disposition of New Shares and/or ADRs will realise an amount equal to the US dollar value of the foreign currency on the date of sale (or in the case of cash 869

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- basis and electing accrual basis taxpayers, the US dollar value of the foreign currency on settlement date). If a US Holder receives foreign currency upon a sale or exchange of New Shares and/or ADRs, gain or loss, if any, recognised on the subsequent sale, conversion or disposition of such foreign currency will be ordinary income or loss, and will generally be income or loss from sources within the US for foreign tax credit limitation purposes. However, if such foreign currency is converted into US dollars on the date received by the US Holder, a cash basis or electing accrual US Holder should not recognise any gain or loss on such conversion. Subject to the discussion under "Backup Withholding and Information Reporting", a Non-US Holder generally will not be subject to US federal income or withholding tax on any gain realised on the sale or exchange of New Shares and/or ADRs unless: (a) that gain is effectively connected with the conduct by that Non-US Holder of a trade or business in the US, (b) in the case of any gain realised by an individual Non-US Holder, that holder is present in the US for 183 days or more in the taxable year of the sale or exchange and certain other conditions are met, or (c) the Non-US Holder is subject to tax pursuant to provisions of the Code applicable to certain expatriates. Redemption of New Shares and/or ADRs Subject to the discussion under "Passive Foreign Investment Company Considerations", a redemption of New Shares and/or ADRs by Corp will be treated as a sale of the redeemed New Shares and/or ADRs by the US Holder (which is taxable as described under "Sale or Other Disposition of New Shares and/or ADRs") or in certain circumstances, as a distribution to the US Holder (which is taxable as described under "Distributions"). Passive Foreign Investment Company Considerations A corporation organised outside the US generally will be classified as a passive foreign investment company ("PFIC") for US federal income tax purposes in any taxable year in which either: (a) at least 75 per cent. of its gross income is "passive income", or (b) on average at least 50 per cent. of the gross value of its assets is attributable to assets that produce "passive income" or are held for the production of passive income. Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities and securities transactions. In determining whether it is a PFIC a foreign corporation is required to take into account a pro rata portion of the income and assets of each corporation in which it owns, directly or indirectly, at least a 25 per cent. interest. Corp believes that it is not, and it does not expect to become, a PFIC, for US federal income tax purposes. However, because this is a factual determination made annually at the end of the taxable year, there can be no assurance that Corp will not be considered a PFIC for any future taxable year. If it were a PFIC in any year, special, possibly materially adverse, consequences would (as discussed below) result for US Holders. If Corp were a PFIC in any year during which a US Holder owns New Shares and/or ADRs the US Holder will be subject to additional taxes on any excess distributions received from Corp and any gain realised from the sale or other disposition of the New Shares and/or ADRs (whether or not Corp continues to be a PFIC). A US Holder has an excess distribution to the extent that distributions on the New Shares and/or ADRs during a taxable year exceed 125 per cent. of the average amount of distributions received during the three preceding taxable years (or, if shorter, the US Holder's holding period). To compute the tax on the excess distributions or any gain, (a) the excess distribution or the gain is allocated rateably over the US Holder's holding period, (b) the amount allocated to the current taxable year and any year before Corp became a PFIC is taxed as ordinary income in the current year, and (c) the amount allocated to other taxable years is taxed at the highest applicable marginal rate in effect for each year and an interest charge is imposed to recover the deemed benefit from the deferred payment of the tax attributable to each year. Some of the rules with respect to distributions and dispositions described above may be avoided if a US Holder makes a valid "mark-to-market" election (in which case, subject to certain limitations, the US Holder would essentially be required to take into account the difference, if any, between the fair market value and the adjusted tax basis of its New Shares and/or ADRs at the end of a taxable year as ordinary income (or, subject to certain limitations, ordinary loss), in calculating its income for such year). In addition, gains from an actual sale or other disposition of New Shares and/or ADRs will be treated as ordinary income, and any losses will be treated as 870

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 17: TAX -------------------------------------------------------------------------------- ordinary losses to the extent of any "mark-to-market" gains for prior years. A "mark-to-market" election is only available to US Holders in any tax year that the PFIC stock is considered "regularly traded" on a "qualified exchange" within the meaning of applicable US Treasury regulations. PFIC stock is "regularly traded" if, among other requirements, it is traded on at least 15 days during each calendar quarter. Both the London Stock Exchange and NASDAQ will constitute a qualified exchange for this purpose. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO WHETHER THE NEW SHARES AND/OR ADRS WOULD QUALIFY FOR THE MARK-TO-MARKET ELECTION AND WHETHER SUCH ELECTION IS ADVISABLE. The foregoing rules with respect to distributions and dispositions may be avoided if a US Holder is eligible for and timely makes a valid "QEF election" (in which case the US Holder would be required to include in income on a current basis its pro rata share of Corp's ordinary income and net capital gains). In order to be able to make the QEF election, Corp would be required to provide a US Holder with certain information. Corp may decide not to provide the required information Each US Holder of New Shares and/or ADRs must make an annual return on IRS Form 8621, reporting distributions received and gains realised with respect to each PFIC in which it holds a direct or indirect interest. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS ARE URGED TO CONSULT THEIR OWN TAX ADVISERS REGARDING WHETHER AN INVESTMENT IN NEW SHARES AND/OR ADRS WILL BE TREATED AS AN INVESTMENT IN PFIC STOCK AND THE CONSEQUENCES OF AN INVESTMENT IN A PFIC. BACKUP WITHHOLDING AND INFORMATION REPORTING Backup withholding and information reporting requirements may apply to certain payments to US Holders of dividends on New Shares and/or ADRs, principal or interest (including OID) paid or accrued on New Senior Notes and New Junior Notes, and to the proceeds of a sale or redemption of New Shares, New Senior Notes, New Junior Notes or ADRs. Corp, its agent, a broker, or any paying agent, as the case may be, may be required to withhold tax from any payment that is subject to backup withholding at a maximum rate of 30 per cent. (which rate is scheduled to change as a result of recent US legislation) of such payment if the US Holder fails (a) to furnish the US Holder's taxpayer identification number, (b) to certify that such US Holder is not subject to backup withholding or (c) to otherwise comply with the applicable requirements of the backup withholding rules. Certain US Holders (including, among others, corporations) are not subject to the backup withholding and information reporting requirements. Non-US Holders who hold their New Shares, New Senior Notes, New Junior Notes or ADRs through a US broker or agent or through the US office of a non-US broker or agent may be required to comply with applicable certification procedures to establish that they are not US Holders in order to avoid the application of such information reporting requirements and backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a holder generally may be claimed as a credit against such holder's US federal income tax liability provided that the required information is timely furnished to the IRS. PERSONS CONSIDERING THE PROPOSALS INCLUDED IN THESE DOCUMENTS SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THEIR QUALIFICATION FOR EXEMPTION FROM BACKUP WITHHOLDING AND THE PROCEDURE FOR OBTAINING THIS EXEMPTION. 871

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 18 PARTICULARS OF THE SCHEME IMPLEMENTATION DEED As described in part I, Section 2, Part D.5 the Scheme Implementation Deed was entered into for the primary purpose of ensuring that legally binding arrangements were in place governing the rights and obligations between Corp, plc, E-A Continental Limited, Ancrane, Marconi Nominees Limited, British Sealed Beams Limited and various other Group Companies. The detailed obligations and undertakings contained in the Scheme Implementation Deed may be summarised as follows: a. NON-VOTING UNDERTAKINGS Ancrane, a subsidiary of plc, has various claims against Corp and plc. Ancrane has undertaken not to attend or vote or to use any other rights or powers available to it as either a Corp Scheme Creditor, a plc Scheme Creditor or as a Bondholder at any of the Scheme Meetings at which it is entitled to attend and vote. Ancrane has also undertaken not to take any steps to canvass, solicit or entice any other person, firm or company to attend and/or vote on its behalf at any of the Scheme Meetings at which it is entitled to attend and vote. It should be noted that these arrangements do not however prevent Ancrane from submitting a Scheme Claim or Scheme Claims under either or both of the Corp Scheme and the plc Scheme. Corp has a claim against plc and has undertaken not to attend or vote at the plc Scheme Meeting nor submit a Form of Proxy with respect to its Scheme Claim. This does not, however, prevent Corp from submitting a Scheme Claim under the plc Scheme. Certain other Group Companies and British Sealed Beams Limited have various claims against Corp and plc and have therefore also undertaken not to attend or vote at the Scheme Meetings or use any other rights or powers available to them as either a Corp Scheme Creditor or a plc Scheme Creditor to attend or vote at any of the Scheme Meetings at which they are entitled to attend and vote. b. ANCRANE/E-A CONTINENTAL ARRANGEMENTS E-A Continental Limited, a subsidiary of Corp, owed plc approximately L219 million and had a receivable of approximately L363 million due from Corp. Pursuant to a deed of assignment entered into on 27 March 2003 between Corp, plc and E-A Continental Limited, Corp agreed to the assignment by E-A Continental Limited to plc of its L363 million receivable. The assignment of the L363 million receivable was in consideration for the release by plc of the L219 million owed to plc by E-A Continental Limited and the transfer by E-A Continental Limited to plc of the balance of approximately L2,000,000 held on account with HSBC. On 27 March 2003, a deed of assignment was entered into between Corp, plc and Ancrane under which plc agreed to the assignment of the L363 million receivable to Ancrane in consideration for the issue to plc by Ancrane of a share at a premium equal to the market value of the L363 million receivable. Ancrane re-registered as an unlimited company pursuant to section 49 of the Act on 25 March 2003. Ancrane will prior to the Scheme Meeting of the plc Scheme Creditors reduce its share capital (including for this purpose its share premium account) to L100 to enable it to make a repayment of capital in specie to plc of its interest in all of its assets, save for L100 and the benefit of a specific covenant by Corp, and will make a repayment of such capital in specie to plc. c.

FINMECCANICA GUARANTEE Under a Share Purchase Agreement dated 2 August 2002, Marconi (Bruton Street) Limited sold all of the shares in Mobile (the Italian holding company for the strategic communications business) to Finmeccanica SpA. A parent company guarantee in favour of Finmeccanica SpA was required to be given as part of the share sale (the "Finmeccanica Guarantee"). plc was therefore party to the Share Purchase Agreement (as guarantor) pursuant to which, among other things, it guaranteed the performance by Marconi (Bruton Street) Limited of its obligations under the Share Purchase Agreement and the related transaction documents (including a tax covenant, a transitional services agreement, a custody deed and a disclosure letter). Finmeccanica SpA, Corp and plc have entered into a deed of novation and amendment (the "Finmeccanica Guarantee Deed of Novation") under which, with effect from the Effective Date of the Corp Scheme, the Finmeccanica Guarantee and all other remaining obligations of plc under the Share Purchase Agreement will be novated from plc to Corp.

The purpose of the revolving facilities was: (i) in the case of the 364-day facility, to finance the bridging and liquidity requirements of plc and its subsidiaries; and (ii) in the case of the 5-year facility, to finance the general corporate purposes of plc and its subsidiaries.

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 19: MATERIAL CONTRACTS -------------------------------------------------------------------------------- (v) plc's guarantee of the Eurobonds is not, or is claimed by plc not to be, in full force and effect (other than following its termination in accordance with its terms).

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 19: MATERIAL CONTRACTS -------------------------------------------------------------------------------- pending agreement or determination of Barclays' claims (if any) against certain operating subsidiaries of plc ("Opcos") in relation to certain potential liabilities. Which escrow account is established will depend on whether the Restructuring is successful or not. The ESOP Escrow Agreement: (i) sets out the terms on which, upon the Corp Scheme becoming effective, approximately L145 million will be held in escrow and creates a framework for resolving Barclays' entitlement (if any) to the balance of such cash; (ii) provides for a number of detailed assumptions to assist a court with such determination; (iii) sets out the terms, if the Corp Scheme does not become effective, on which a certain amount of cash will be paid into escrow in accordance with the interim security arrangements and creates a framework for resolving Barclays' entitlement (if any) to the balance of such cash; and (iv) provides for the release (on the Corp Scheme becoming effective) of any claims that plc or Barclays may have against each of the Opcos under certain funding letters entered into by the Opcos. The terms of the ESOP Escrow Agreement dealing with the money to be held in escrow upon the Corp Scheme becoming effective have been superseded by the ESOP Settlement Agreement referred to below. In other respects, the ESOP Escrow Agreement continues to apply. 3.2 LOAN FACILITY AGREEMENT BETWEEN CORP AND BEDELL CRISTIN TRUSTEES LIMITED ("BCTL") DATED 21 FEBRUARY 2001 (AS AMENDED)*. Corp has set up a loan facility for BCTL; the current level of the drawdown is approximately L215 million. BCTL is entitled to drawdown from the facility only as and when collateral payments become due under equity derivative transactions with Salomon Brothers International Limited ("SBIL") and UBS AG ("UBS"). The maximum collateral payments have now been made. The loan is limited in recourse. BCTL will incur no liability to repay the loan until its obligations to SBIL and UBS have been fully discharged. BCTL's liabilities to Corp are further restricted to the remaining assets of the trust fund (roughly L40,000). Accordingly there is no likelihood that BCTL will be able to repay the loan. 3.3 AGREEMENT DATED 6 DECEMBER 2002 BETWEEN PLC, BEDELL CRISTIN TRUSTEES LIMITED (AS TRUSTEES OF THE MARCONI EMPLOYEE TRUST) ("BCTL") AND UBS AG ("UBS") RELATED TO THE CLOSE-OUT OF THE EQUITY DERIVATIVE TRANSACTION BETWEEN BCTL AND UBS+. On 6 December 2002, BCTL, UBS and plc agreed to close out the equity derivative transaction between BCTL and UBS (in respect of which plc guaranteed BCTL's obligations). As a result of that close out the parties agreed that a net termination amount of L11,230,249.68 is owed by BCTL to UBS and that plc's liability under its guarantee is limited to that net termination amount (plus interest). The net termination amount bears interest at 5.01 per cent. per annum. With effect from 25 March 2003, the net termination amount is payable on demand. However UBS's right to demand payment is now limited by the standstill provisions in the ESOP Settlement Agreement as described in part I, section 2, Part D.2. 3.4 ESOP SETTLEMENT AGREEMENT DATED 26 MARCH 2003 BETWEEN CORP, PLC, HSBC, BARCLAYS, SBIL, UBS AG AND BEDELL CRISTIN TRUSTEES LIMITED.* On 26 March 2003, Corp and plc reached agreement with the ESOP Derivative Banks for a settlement of their ESOP derivative related claims against the Group.

The purposes for which the Performance Bonding Facility is available include supporting financing facilities which have been provided to members of the Group for the purpose of supporting directly obligations of members of the Group in the ordinary course of the Group's trade or business (other than obligations in respect of financial indebtedness). For example, this may be used in connection with supporting a facility in a foreign currency where such foreign currency is not available under the Performance Bonding Facility. See part I, Section 2, Part D.4 for a more detailed description of the terms of the Performance Bonding Facility. Under the Security Over Cash Agreement, MBL has granted, in favour of HSBC (as security trustee), security over the accounts into which cash collateral deposits will be made in respect of bonds issued under the Performance Bonding Facility. 4.2 WORKING CAPITAL FACILITY DATED 26 MARCH 2003 RELATING TO A NEW US$22.5 MILLION REVOLVING CREDIT FACILITY BETWEEN MARCONI COMMUNICATIONS, INC. ("MCI") AS BORROWER AND LIBERTY FUNDING, L.L.C. ("LIBERTY"), AS LENDER. Subject to customary exculpatory exceptions, MCI's obligations under the Working Capital Facility will be limited recourse, and will be secured by a first mortgage lien on MCI's real property and improvements, including fixtures, located in Warrendale, Pennsylvania, USA. part I, Section 2, Part D.4 contains a more detailed description of the terms of the Working Capital Facility.

MCI has agreed to assign to Liberty all of its rights under all leases affecting the property, including all extensions, renewals and modifications and subleases, together with all guarantees of any tenant's or subtenant's performance; and (iv) environmental indemnity dated 26 March 2003 between MCI and Liberty, under which MCI agrees to provide Liberty with assurances, agreements and indemnities regarding environmental matters, as a material inducement for Liberty to make the loan. 4.3 COLLATERISATION OF SYNDICATE BANK EXISTING BOND EXPOSURES. In order to be satisfied that, on a portfolio view, the L55 million deposit which was permitted to be made into the Existing Performance Bond Escrow Account by Corp would be an adequate reserve in respect of existing performance bonds, Corp entered into arrangements with the Syndicate Bank issuers of existing performance bonds. These arrangements, which are described in more detail in part 1, Section 2, Part D.4, were evidenced by letters from Corp to the banks named below which were countersigned by those banks: (i) letter dated 14 March 2003 from Corp to Australia and New Zealand Banking Group Limited; 894

The Security Trust and Intercreditor Deed will bind each of the Secured Creditors and each of the Obligors, including the Issuer and the Guarantors of the Notes. The Notes are subject to the Security Trust and Intercreditor Deed pursuant to which the exercise by each Note Trustee of its rights under the Security Documents on behalf of the Noteholders and of the rights of the Noteholders under the relevant Notes may in certain circumstances be directed by, or subject to the prior consent of, other parties to the Security Trust and Intercreditor Deed. Noteholders are bound by, and deemed to have notice of, all the provisions of the Security Trust and Intercreditor Deed. The purpose of the Security Trust and Intercreditor Deed is to regulate, inter alia: (a) the ranking of claims of the Secured Creditors; (b) the exercise, acceleration and enforcement of rights by the Secured Creditors; (c) the rights of Secured Creditors to instruct the Security Trustee; (d) the rights of the Senior Note Trustee to issue a Standstill Notice; (e) the rights of the Secured Creditors during a Standstill Period and the effects of the Standstill Period; (f) the giving of consents and waivers and the making of modifications to the Relevant Documents; and (g) the rights of the Secured Creditors and the priorities following a Payment Stop Event. The Security Trust and Intercreditor Deed provides for the ranking in priority of payment of the claims of the Secured Creditors and for the subordination of intercompany claims by the Issuer and those of its Subsidiaries that are parties to the Security Trust and Intercreditor Deed. A more complete description of the Security Trust and Intercreditor Deed is set out in Appendix 10. 5.6 ESCROW ARRANGEMENTS ESCROW AGREEMENT TO BE DATED ON OR BEFORE THE ISSUE DATE BETWEEN, INTER ALIA, CORP AND THE SECURITY TRUSTEE.* This Escrow Agreement governs the relationship between Corp, the Security Trustee and the Escrow Bank (as defined therein) regarding the payment of proceeds into and the release of proceeds from the Mandatory Redemption Account and the Existing Performance Bond Escrow Account, each as defined in and more fully set out in Appendix 8. 5.7 MEMORANDUM OF UNDERSTANDING DATED 25 MARCH 2003 BETWEEN CORP, PLC AND THE UNITED STATES PENSION BENEFIT GUARANTY CORPORATION ("PBGC")* Corp and plc have entered into a legally binding memorandum of understanding with the PBGC under which the PBGC has agreed (i) that it will not take any action in connection with the Restructuring to 907

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 19: MATERIAL CONTRACTS -------------------------------------------------------------------------------- involuntarily terminate either of the two tax-qualified defined benefit pension plans sponsored by Greensboro Associates, Inc., an indirect wholly owned subsidiary of Corp (the "US PENSION PLANS") and (ii) that it will withdraw any contingent claims filed by the PBGC under the plc Scheme as of the Effective Date of the Corp Scheme. Under the memorandum of understanding with the PBGC, (i) Corp or the contributing employers to the US Pension Plans will make annual contributions to the US Pension Plans in an amount equal to each US Pension Plan's respective minimum funding requirements under the applicable United States statutes, including ERISA, and the Code, or, if greater, the respective US Pension Plans' normal cost, plus an additional US$9 million per annum payable in quarterly instalments of US$2.25 million commencing as of 30 June 2003, but only to the extent deductible, (ii) Corp will provide a guarantee to the PBGC of the obligations of its subsidiaries in the United States with respect to (x) such subsidiaries' respective obligations to make contributions to the US Pension Plans as provided in clause (i) of this sentence and, (y) any liability owing to the US Pension Plans or the PBGC if either or both of the US Pension Plans should terminate while such guarantee is in effect. To the extent that any required annual contributions in excess of annual normal cost would result in a credit balance under either of the US Pension Plans which could otherwise be used to satisfy minimum funding requirements, the memorandum of understanding with the PBGC significantly limits such usage. The memorandum of understanding with the PBGC provides that if Corp intends to sell any of its business units in the United States to a third-party purchaser whose debt immediately following the consummation of such transaction is not then rated investment grade, no proposed transfer of assets and liabilities of the US Pension Plans to a pension plan of the third-party purchaser may be made without the consent of the PBGC. To the extent that any sale of a business unit will not include the transfer of the assets and liabilities of the applicable US Pension Plan to a pension plan of the purchaser of such business unit, Corp will cause a portion of the proceeds of such business unit sale equal to the net shortfall, if any, under the applicable US Pension Plan which is attributable to such business unit to be contributed to the applicable US Pension Plan upon completion of such business unit sale, with the amount to be contributed based on the then applicable PBGC safe harbor assumptions used for plan termination purposes (subject to any applicable limitations under ERISA or the Code with respect to deductibility of such contributions or otherwise). The memorandum of understanding with the PBGC also requires that one of the US Pension Plans be fully funded or transferred to a purchaser of a business unit upon the occurrence of certain business unit sales. The memorandum of understanding with the PBGC further provides that Corp will consent to jurisdiction in United States federal district courts and will agree as a contractual matter to be jointly and severally liable with its US subsidiaries which are participating employers in the US Pension Plans with respect to its obligations under the PBGC memorandum of understanding. As part of its obligations under the memorandum of understanding with the PBGC, Corp will provide, or cause its US subsidiaries to provide, certain specific information relevant to the US Pension Plans to the PBGC on a regular basis during the term of such memorandum of understanding. Corp's obligations under this memorandum of understanding with the PBGC with respect to any US Pension Plan will cease on the earliest to occur of (i) the date that a US Pension Plan is terminated in a standard termination under ERISA, or (ii) on the first date after the fifth anniversary of the Effective Date of the Corp Scheme when either (x) such US Pension Plan has been fully funded on a termination basis for two consecutive years ending on or after the expiration of such five-year period or (y) Corp's debt is rated investment grade. If Corp is acquired at any time while the memorandum of understanding with the PBGC remains in effect and the acquiror's debt is rated investment grade immediately following such sale, the PBGC will agree to review the acquisition of Corp in good faith to determine whether the need for its memorandum of understanding with Corp and plc still exists and whether such memorandum of understanding may then be terminated. 6.

APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 19: MATERIAL CONTRACTS -------------------------------------------------------------------------------- 6.1 LETTERS OF CURRENT INTENTION FROM JPMORGAN CHASE BANK DATED 11 DECEMBER 2002 AND FROM EACH OF HSBC AND THE ROYAL BANK OF SCOTLAND PLC (DATED 13 DECEMBER 2002), TO CORP AND PLC.* Under these letters, the relevant Co-ordination Committee members confirmed their current intention (as at the date of the relevant letter) to support the Restructuring of Corp and plc on the terms and in the manner contemplated by the Heads of Terms. In doing so, each stated their current intentions to consider the Schemes and exercise all votes that they are entitled to in respect of the Bank Facility or any bilateral facility provided by or guaranteed by Corp and/or plc other than claims relating to the Bonds issued by Corp in favour of the Schemes and the Restructuring.

In doing so, whenever any vote is required of such Bondholders in relation to the Schemes, such Bondholders stated their current intention to exercise all votes that they are entitled to in their capacity as Bondholders in favour of the Schemes and the Restructuring and not to act alone or in concert with others, or advise, assist or encourage any person to act in a manner which frustrates the Restructuring. Each such Bondholder reserves the right to change its intention in the future, or if: (a) the Restructuring is not implemented on the basis contemplated in the Heads of Terms; (b) an enforcement event has occurred at any time under the interim security (as described in part I, Section 2, Part D.1); (c) Corp or plc disclaims in writing or publicly expresses an intention not to pursue the Restructuring; a demand for re-payment of the Bank Facility is made or there is an event of default under the Bonds; (d) a public disclosure or announcement is made for the possible acquisition of all or substantially all of: (i) the business, operations and/or assets of Corp; or (ii) the financial indebtedness of Corp and/or plc owed to the Bank Creditors (as defined in part I, Section 2, Part D.1) and to persons with an interest in the Bonds; or (e) Corp or Highrose Limited violates, breaches or repudiates any provision of the undertakings given by them in favour of the members of the Informal Committee of Bondholders on 13 September 2002 (and amended on 13 December 2002 and 28 March 2003) in connection with the interim security. 909

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 20 LITIGATION Except as set out below in paragraphs 1 to 24 below, no member of the Group is or has been engaged in nor, so far as the Group is aware, has pending or threatened by or against it, any legal or arbitration proceedings which may have, or have had during the 12 months preceding the date of this document, a significant effect on the Group's financial position. Where a liquidated sum is claimed, a de minimis figure of L5 million has been applied in determining which claims may have a significant effect. The figures given are the full amounts claimed by the claimants in each case, which may be much greater than the amounts the claimants realistically believe they can recover. Corp, plc and the other Group Companies intend to defend claims vigorously. Claims against Corp and plc may be compromised by the Corp Scheme and plc Scheme, respectively, but claims against subsidiaries of Corp are not subject to the Schemes. CLAIMS AGAINST THE CORP GROUP 1. Corp, FORE Systems Inc. ("FORE Systems") and 13 persons who were then directors and/or senior executives of FORE Systems are defendants in a consolidated class action lawsuit filed in the United States District Court for the Western District of Pennsylvania on behalf of the public shareholders of FORE Systems (other than defendants and their respective affiliates). The action alleges that Corp violated federal securities law in relation to Corp's tender offer for FORE Systems' shares, FORE Systems' grant of share options to certain of the individual defendants and the treatment afforded the individual defendants' share options in that tender offer and in the merger agreement between Corp and FORE Systems. Millionerrors Investment Club is the first named plaintiff. The complaint seeks unspecified damages, counsel and expert fees, other costs of the claim and other unspecified relief, although the plaintiff's lawyers have indicated that the claim is worth $450 million. On 21 August 2002 the District Court granted summary judgement in favour of the defendants on all claims. On 23 September 2002, the plaintiffs filed a notice of appeal. The appeal is expected to take approximately one year. Potential liabilities in respect of the claim against Corp will be compromised pursuant to the Corp Scheme. 2. FORE Systems, together with six of its former directors and officers, are defendants in a consolidated class action lawsuit filed in the United States District Court for the Western District of Pennsylvania on behalf of a class of persons (other than defendants and their respective affiliates) who purchased FORE Systems securities during the period 19 July 1996 to 1 April 1997, inclusive. Robert K. Bell is the first named plaintiff. The plaintiffs allege that, during this period, FORE Systems misrepresented material facts relating to its results of operations, competitive position and future prospects and concealed its alleged deterioration, declining growth and inability to compete successfully until the 1 April 1997 preliminary release of FORE Systems' projected results of operations for the year ended 31 March 1997. The plaintiffs also allege that FORE Systems' financial statements for the quarters ended 30 June, 30 September and 31 December 1996 improperly recognised revenues on sales to certain customers. These alleged misrepresentations are said to constitute violations of the anti-fraud provisions of section 10(b) of the U.S. Securities Exchange Act of 1934 and, as to the individual defendants, of section 20(a) of the U.S. Securities Exchange Act of 1934. The plaintiffs' consolidated complaint seeks unspecified damages, counsel and expert fees and other costs of suit and other unspecified relief. The defendants have denied all allegations of wrongdoing. Discovery has concluded, and both plaintiffs and defendants have filed their respective pre-trial statements. The plaintiffs' damages expert had initially estimated damages at $792 million, then $865 million and then $724 million. By order dated 2 August 2002, the court granted the defendants' motion in limine to exclude testimony from the plaintiffs' damages expert. At the same time the court denied a motion to exclude testimony from the plaintiffs' liability expert and discussed a proofs of claim procedure which if liability were found, would follow a liability trial. The court also certified the damages issue for an interlocutory appeal to the Court of Appeals. The plaintiffs did not appeal the court's decision. The court will now take up other issues raised 910

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 20: LITIGATION -------------------------------------------------------------------------------- in the Group's motions. Potential liabilities in respect of this claim are not subject to the Schemes as the claim is not against Corp or plc. 3. FORE Systems is a defendant in a lawsuit filed by Bell Communications Research, Inc. (formerly known as Bellcore, now named Telcordia Technologies Inc. ("Telcordia")) on 14 October 1998 in the United States District Court for the District of Delaware. Telcordia, a patent holder, alleges that FORE Systems has infringed and continues to infringe four patents owned by Telcordia, and seeks unspecified damages for past infringement and an injunction against future infringement. FORE Systems has denied infringement and asserted the affirmative defences of invalidity, unenforceability, laches, equitable estoppel, implied license, misuse and unclean hands. In addition, FORE Systems has counterclaimed for a declaratory judgment on non-infringement, invalidity, unenforceability, laches, equitable estoppel, implied license, misuse and unclean hands and asserted affirmative claims seeking damages for reformation of contract based on fraud, breach of the covenant of good faith and fair dealing, negligent misrepresentation and common law unfair business practices and competition. Discovery in this case has closed. The court conducted a claim construction hearing in late August 2000 and subsequently entered an order construing the claims of the patents in suit. Telcordia, taking the position that it could not, given the court's patent claim construction, prevail on its claims of infringement at trial, moved the court to enter an order finding that FORE Systems had not infringed the patents in suit so that the case would be procedurally postured for appeal. FORE Systems subsequently moved the court to require that Telcordia identify which of the patent claim elements construed by the court it contends were in error and which preclude Telcordia from proving infringement. That motion has been fully briefed and is pending before the court. On 21 September 2001 the court entered a final judgement of non-infringement. Telcordia filed notice of appeal in October 2001 and filed their opening brief on 18 March 2002. FORE Systems' opening response was filed on 28 May 2002. Telcordia's reply was filed on 23 July 2002. Potential liabilities in respect of this claim are not subject to the Schemes as the claim is not against Corp or plc. 4. FORE Systems is a defendant in a second lawsuit filed by Telcordia, a patent holder, on 8 June 1999 in the United States District Court for the District of Delaware. Telcordia's second lawsuit for an unspecified amount of damages alleges that FORE Systems has infringed two additional Telcordia patents. FORE Systems has denied infringement and asserted the affirmative defences of invalidity, unenforceability, laches, equitable estoppel, implied license, misuse and unclean hands. In addition, FORE Systems has counterclaimed for a declaratory judgment on the issues of non-infringement, invalidity and unenforceability and has alleged that Telcordia infringed one of FORE Systems' patents. Discovery in this case has closed. Telcordia has filed summary judgment motions which are pending before the court. The case was scheduled for trial in November 2000. However, all proceedings have been stayed pending the outcome of the proceedings in the first lawsuit described in paragraph 3 above. Potential liabilities in respect of this claim are not subject to the Schemes as this claim is not against Corp or plc. 5. Systems Management Specialists, Inc. ("SMS") is a defendant in an arbitration brought by Esprit de Corp ("Esprit") in April 2002. This action relates to two outsourcing agreements entered into by Esprit and SMS in 1995 and 1999; Esprit alleges that SMS breached its obligations under the agreement and is seeking at least $8 million. The arbitration between SMS and Esprit has commenced and will be conducted in Los Angeles, California, USA. Initially, the parties had agreed to conduct the arbitration hearing during a two week period in May 2003, with discovery and briefing to take place before that time. However, this may be delayed. plc was originally a party to the arbitration demand under a legal theory alleging that SMS and plc are alter egos of one another. Esprit has since released plc from its original arbitration demand, but has named plc in a federal court proceeding. In response plc moved to stay the federal court proceeding until after the arbitration between SMS and Esprit has concluded. The court granted plc's motion to stay, and therefore Esprit will be permitted to proceed with its claims against plc only after the arbitration between SMS and Esprit is completed, and only to the extent Esprit prevails on any of its claims in its arbitration against SMS. Potential liabilities in respect of the claim against plc will be compromised pursuant to the plc Scheme. 6. Corp and Marconi Commerce Systems Inc. ("MCSI") are defendants in two actions brought by a former employee, Larry Anthony Gillus ("Gillus"). The complaints are that Gillus suffered racial discrimination 911

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 20: LITIGATION -------------------------------------------------------------------------------- and subsequent retaliatory action whilst employed by Gilbarco (subsequently known as Marconi Commerce Systems Inc., which has now been sold to subsidiaries of Danaher Corporation plc). A second claim has been brought against plc and Marconi Commerce Systems Inc. for retaliation and intentional infliction of emotional distress alleged to have occurred after he bought the original action. Counsel for both parties have agreed that if plc is the correct defendant and not Corp, this change can be made. Gillus' counsel has stated that he is seeking a total of $19 million in respect of both claims. The claims have been selected for a mediated settlement conference. Potential liabilities in respect of the claims against Corp and plc will be compromised pursuant to the Schemes being implemented in accordance with their terms. 7. Corp, plc, Marconi Inc. and Marconi Data Systems Inc. are defendants in an action brought by a former employee, Thomas Edeus ("Edeus"). The complaint asserts three causes of action; firstly that Edeus was unlawfully deprived of benefits to which he was entitled under Marconi Data Systems Inc's United States severance plan; secondly for failure to provide Edeus with a summary plan description relating to the severance plan; and thirdly for age discrimination in employment. The plaintiff has purported to have made out claims in various specified amounts totalling over $901,000, some of which may be in the alternative, and also unspecified punitive damages, liquidated damages and front and back pay, making the impact of this claim on the Group difficult to assess. An answer and affirmative defences have been filed on behalf of all defendants. Potential liabilities in respect of the claims against Corp and plc will be compromised pursuant to the Schemes. 8. On 4 October 2000, Alcatel SA and Alcatel CIT, both French companies ("Alcatel"), filed a claim against plc, Marconi Communications Limited and Marconi Communications SpA alleging infringement of two patents held by Alcatel group companies. Alcatel and Marconi entered into a mutual patent cross licence agreement effective 1 April 2002 in respect of both companies' patent portfolios which calls for a series of payments by plc. The amount of these payments has no significant effect on the financial position or profitability of the Group. This settled all claims brought by Alcatel. The cross licence applies to patents and patent applications of plc and Alcatel filed prior to 1 April 2002. The cross licence expires on 31 March 2009. Potential liabilities in respect of this claim are excluded from the Schemes. 9. Stringfellow and Plessey Precision Metals are defendants in an action brought in the Superior Court of California in May 1998. A toxic tort claim was filed by several thousand residents of Riverside County who live adjacent to the Stringfellow Acid Pits Waste Disposal Site. There are currently several hundred plaintiffs. The claim is still in its early stages and, therefore, no estimate of Plessey's potential liability is currently available. Plessey was a minor generator of hazardous materials on the site compared to others involved, however. A Case Management Order was entered into in early 2001 and the case is still in the early discovery stage. The defendants are seeking dismissal on grounds of statutes of limitation. Potential liabilities in respect of this claim are not subject to the Schemes as the claim is not against Corp or plc. 10. Inglis Limited and The English Electric Company Limited ("English Electric") are defendants in an action brought by Manitoba Hydro. In the early 1960s, Manitoba Hydro contracted with Inglis Limited to design and manufacture (amongst other equipment) three turbines for the hydro electric plant at Grand Rapids in the United States. Inglis Limited worked closely with English Electric, who prepared certain aspects of the turbine design. One of the turbines exploded in March 1992. Manitoba Hydro is suing Inglis Limited for negligence and breach of contract in the design and manufacture of the turbines, and English Electric for negligence in relation to the design. In June 1998 Manitoba Hydro were granted leave to commence their action against English Electric and Inglis Limited and the proceedings are progressing, the documentary disclosure phase having been largely completed and examination for discovery of witnesses being partly undertaken. Manitoba Hydro has pleaded (in broad terms) around 35 million Canadian dollars (approximately L14 million). This sum is exclusive of interest which could approximately double that figure as the explosion took place 10 years ago. This amount assumes 100 per cent. liability on the part of English Electric, which is denied. Potential liabilities in respect of the claim are not subject to the Schemes as the claim is not against Corp or plc. 11. Datang Telecom Technology Co. Ltd, Optical Communication Branch ("Datang") has indicated that it may bring a claim against Chengdu Marconi Communications Ltd. On 24 August 2000 Chengdu Marconi Communications Ltd entered into an Original Equipment Manufacture agreement with Datang. Datang 912

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 20: LITIGATION -------------------------------------------------------------------------------- has approximately US$5.2 million on account payable to Chengdu Marconi Communications Ltd but has not paid as it claims that it has been unable to sell US$7 to 9 million of products purchased from Chengdu Marconi Communications Ltd due to their quality. Datang has indicated that it will not pay the outstanding sums and may bring court proceedings against Chengdu Marconi Communications Ltd in China. The value of such a claim might be in the region of US$7 to 9 million, the value of the products that Datang claims it has been unable to sell, but could potentially be for US$18 million, the value of the entire contract. Potential liabilities in respect of this claim are not subject to the Schemes as the claim is not against Corp or plc. 12. On 26 March 2002 Railtrack Telecom Services Ltd ("RTSL") (now known as RT Group Telecom Services Limited), a joint venture partner, served a claim against Corp in respect of its failure to pay in February 2002 an amount of L20 million plus daily interest in an amount of L3,287 in respect of the purported exercise by RTSL of a contractual option to put 1,324,054 ordinary shares in Easynet Group plc on to Corp. Corp had, prior to receipt of the claim, indicated its intention to claim or counterclaim against RTSL in respect of its acts, omissions, misrepresentations and breaches of its obligations to Corp arising out of or in respect of certain agreements and transactions relating to ipsaris Limited and Ultramast Limited (a joint venture company in which RTSL and Corp each held 50 per cent. of the shares). Corp then raised its counterclaims as a complete defence and advised RTSL that the amount of Corp's claims against RTSL was greater than the claim that RTSL had brought against Corp. RTSL applied for a summary judgment hearing, which took place on 15 July 2002, on the grounds that Corp's claims had no real prospect of success. The court did not grant summary judgment in favour of RTSL, recognising that Corp might have a valid counterclaim which could be set off against amounts due under the option. However, the court did order that Corp pay the disputed L20 million plus interest into court, reflecting the court's concerns about whether the counterclaim by Corp would ultimately succeed, and also the fact that RTSL was entitled to put the Easynet Group plc shares on Corp, and that it would be unfair for Corp to acquire the shares without making any payment. Corp paid the required sum into court. A settlement of all outstanding litigation was reached with RTSL, subject to court approval of a capital reduction in Ultramast Limited. The court approved the capital reduction on 21 February 2003. 13. Marconi Communications Ltd ("MCL") has settled claims which were brought by Alstom Transport Ltd ("Alstom"), a sub-contractor, in an arbitration brought under International Chamber of Commerce rules in respect of a sub-contract that Alstom entered into with MCL on 26 May 1995 for the supply of certain communications equipment and systems for installation on the Northern Line of London's underground system. Alstom requested the arbitration on 25 May 2001. MCL submitted a full defence. Certain preliminary matters were heard and an initial hearing into the substance of the claim took place. In a related action, Alstom Transport Ltd and three other Alstom subsidiaries issued proceedings in the English courts in September 2001 in relation to alleged misrepresentations or breach of warranties made by MCL as to the costs of operating the communications equipment and systems to be installed pursuant to this sub-contract. Settlement has been reached in relation to both these claims. MCL will provide further products and services to Alstom pursuant to a revised supply contract and a new maintenance contract was entered into as of 6 January 2003. Marconi's obligations pursuant to these new contracts are guaranteed by Marconi Communications Holdings Limited and are the subject of collateralised performance bonds to a value of L2.5 million and L1 million respectively for the supply and maintenance contracts. The arbitration has also been discontinued. Potential liabilities in respect of these claims are not subject to the Schemes as the claims are not against Corp or plc. 14. Corp was the defendant in an action brought by DrKW Finance Ltd ("DrKW") which has now been settled. The claim was for L12,289,860.15 plus interest due or scheduled to become due under a payment plan agreement between Oracle Corporation UK Ltd ("Oracle") and Corp. Oracle assigned the relevant agreement, a software licensing agreement, to DrKW. On 11 October 2002 DrKW obtained summary judgment for the full amount claimed plus interest. On the same day Corp agreed a settlement of the claim with DrKW and DrKW agreed not to enforce the judgment. Corp has complied with its settlement obligations and has no further liability in respect of this claim and therefore it is not subject to the Schemes. 913

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 20: LITIGATION -------------------------------------------------------------------------------- 15. There is an outstanding tax dispute between the Indian tax authorities and Corp, English Electric and Associated Electrical Industries Limited ("AEI"). In 1989/90, as part of the reorganisation of the group's European operations, Corp, English Electric and AEI transferred their shareholdings in The General Electric Company of India Limited ("GEC India"), The English Electric Company of India Limited ("EE India") and GEC Power Engineering Services of India Limited ("GEP India") to a Dutch company, GEC Alsthom NV ("Alsthom"). The Indian tax authorities claim that this transfer gives rise to an Indian capital gains tax charge for each of Corp, English Electric and AEI (although this is one of the issues in dispute). An advance Indian capital gains tax payment had to be made before the Indian authorities would issue a no-objection certificate, which was required before the transfer could proceed. This advance payment was based on the value of GEC India, EE India and GEP India at the date of the no-objection certificate. The Indian tax authorities have, however, assessed Corp, English Electric and AEI to tax on the basis of the value of GEC India, EE India and GEP India at the date of the actual transfer, which could give rise to a tax liability of up to L11 million (of which L3 million relates to Corp). Corp, English Electric and AEI are disputing this liability and the basis of valuation in the Indian courts and in pursuance of interim orders of the Indian court have deposited L2.686 million with the Indian tax authorities. Potential liabilities in respect of this claim are excluded from the Schemes. CLAIMS BROUGHT BY THE CORP GROUP The following represent the largest outstanding claims made on behalf of the Corp Group: 16. Marconi Communications, Inc. ("MCI") is the claimant in two actions against Vidar SMS Co., Ltd. ("Vidar"), a company with its principal place of business in Taiwan. In May 2000, MCI brought an International Chamber of Commerce arbitration proceeding against Vidar in connection with Vidar's breaches of an Engineering Services Agreement between Vidar and a Marconi-acquired company, RELTEC Corporation. In August 2002, the arbitration tribunal awarded MCI $25,879,544 under its breach of warranty claims, $5,604,270.12 for prejudgment interest, and $156,702.56 for costs, for a total award of $31,640,516.68. As set out below in paragraph 17 below, Vidar may claim that it has no assets to satisfy this judgment. Corp and plc have no liability in respect of this claim and therefore it is not subject to the Schemes. 17. A second action was brought by MCI against Vidar in May 2000 in the United States Court for the Northern District of Texas for fraud, negligent misrepresentation, Texas common law indemnity and California equitable indemnity, all relating to Vidar's wrongful acts in connection with various business relationships between the parties. On 30 October 2002, the U.S. District Court entered default judgment against Vidar on all claims and assessed MCI's actual damages at $72,402,065 plus prejudgment interest on this amount at the rate of 10 per cent. per annum. Vidar filed a petition for reorganisation in the Taipei (Taiwan) District Court in 2001 and may claim that it has no assets to satisfy the judgments referred to above. However, the Taipei District Court dismissed Vidar's petition on 28 January 2002 based on its lack of viability for reorganisation and the Taiwan High Court dismissed Vidar's appeal of the lower court's ruling on 25 March 2002 based on the same reason. Corp and plc have no liability in respect of this claim and therefore it is not subject to the Schemes. CLAIMS AGAINST THE PLC GROUP 18. plc and four of its current or former officers are defendants in a consolidated class action lawsuit pending in the United States District Court for the Western District of Pennsylvania on behalf of a putative class of all persons (other than defendants and their respective affiliates) who purchased American Depositary Receipts or common stock of plc between 10 April 2001 and 5 July 2001, inclusive. The named plaintiff in respect of the common stock of plc is Tri-Star Farms Ltd and the named plaintiff in respect of the ADRs is City of Miami Fire Fighters' and Police Officers' Retirement Trust Fund. Plaintiffs in these actions allege that, during this period, plc and the individual defendants falsely reassured investors that plc's revenues would rise during the year and that its geographic and business mix left it relatively immune to the economic downturn affecting its competitors. The plaintiffs further allege that on 4 July 2001 defendants belatedly disclosed that tougher trading conditions in the quarter ended 30 June 2001 914

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 20: LITIGATION -------------------------------------------------------------------------------- indicated that plc's sales and operating profits for its fiscal year ended 31 March 2002 would fall significantly from the levels achieved in fiscal 2001. Defendants' alleged misrepresentations are said to violate the anti-fraud provisions of Section 10(b) of the US Securities Exchange Act of 1934 and, as to the individual defendants, Section 20(a) of the US Securities Exchange Act of 1934. The plaintiffs seek class certification, an award of unspecified damages, counsel and expert fees and other costs of suit and other unspecified relief. All defendants filed a motion to dismiss the lawsuit. In ruling upon the defendants' motion to dismiss, the Court entered an order dismissing claims brought on behalf of ordinary shareholders outside the US; the deadline for seeking an interlocutory appeal of this order has passed. The claims brought on behalf of ADR holders and US-resident ordinary shareholders will proceed to discovery and a class certification hearing. Potential liabilities in respect of the claim against plc will be compromised pursuant to the plc Scheme but may have the benefit (in whole or in part) of insurance (see part I, Section 2, Part C.7). 19. In April 2002, 11 former employees of Ten Square Inc. brought a claim against directors of that company for fraud in reducing their compensation package before liquidating the company and restarting it under a different name. The claim is for $2,160,050.91, plus $1 million in punitive damages for all plaintiffs (it is unclear if this is for each of the plaintiffs or in total). The plaintiffs allege that plc was a director of Ten Square Inc., though in fact plc only had a right to appoint a director, a right plc has not recently exercised. Marconi Ventures was also named as a plaintiff on 9 September 2002. The plaintiffs did not serve proceedings upon plc and on 24 October 2002 an order for the dismissal of the claim against plc was entered. However, plc was named in the second amended complaint which was filed on 24 December 2002. plc is aware of the action, but has not been served and is not yet a party to it. Potential liabilities in respect of the claim against plc will be compromised pursuant to the plc Scheme. 20. plc have been named in the federal court proceeding brought by Esprit de Corp described at paragraph 5 above. Potential liabilities in respect of the claim against plc will be compromised pursuant to the plc Scheme. 21. In November 2000 Larry Anthony Gillus, the former employee of Gilbarco Inc mentioned at paragraph 6 above in the claims against the Corp Group brought a claim against plc and Marconi Commerce Systems Inc for retaliation and intentional infliction of emotional distress alleged to have occurred after he brought the original action. The damages claimed are again in excess of L100,000 in punitive damages and in excess of L100,000 in compensatory damages. A claim for breach of contract has also been added. plc denies that there is any connection between it and the subject matter of the claim as it is only an indirect parent of Marconi Commerce Systems Inc., against whom the plaintiff is also claiming. Counsel for both parties have agreed that if Corp is the correct defendant and not plc, this change can be made. The plaintiff's lawyers have indicated that he is seeking a total of $19 million in respect of this claim and the claim against Corp set out at paragraph 6 above. Potential liabilities in respect of the claims against Corp and plc will be compromised pursuant to the Schemes. 22. plc are also defendants in action brought by Thomas Edeus, a former employee of Marconi against Corp, plc, Marconi Inc. and Marconi Data Systems Inc., details of which are set out at paragraph 7 above in the claims against the Corp Group. Potential liabilities in respect of the claims against Corp and plc will be compromised pursuant to the Schemes. 23. In April 2002 Salomon Brothers International Limited ("SBIL") issued proceedings in the English High Court against plc claiming L15,874,960 plus interest under a guarantee given by plc in respect of the trustee for Marconi's employee trust. The trustee, Bedell Cristin Trustee Limited, entered into an ISDA Master Agreement on 15 December 1999 and SBIL allege that an event of default occurred under this on 26 March 2002 when plc as guarantor allegedly became insolvent. The sum of L376,914.16 payable to Bedell Cristin Trustee Limited by SBIL under an ISDA Credit Support Annex has not been paid by SBIL. SBIL contend that this sum will be set off against the amount they are claiming. A case management conference was scheduled for October 2002. However, both parties agreed that this should be postponed. SBIL have agreed to discontinue this claim if the Schemes become effective. Potential liabilities in respect of the claim will be compromised pursuant to the Schemes. 24. plc was a party to the claim brought by Alcatel SA and Alcatel CIT described at paragraph 8 above. Potential liabilities in respect of this claim are excluded from the Schemes. 915

IV.

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 24 SUMMARY OF TERMS OF APPOINTMENT AND SCOPE OF THE ENGAGEMENT OF THE PROSPECTIVE SUPERVISORS AND THE SUPERVISORS Philip Wallace and Richard Heis (both partners of KPMG) have agreed to be appointed as the Prospective Supervisors and as the Supervisors of both the Corp Scheme and the plc Scheme on the terms and conditions set out in the respective Schemes. The terms and conditions of this appointment will be those contained in KPMG's general terms of business, subject to the following modifications: Clause 4: This clause (which relates to confidential information) shall be deemed to have been amended so that neither the Prospective Supervisors nor the Supervisors will identify Corp or plc by name nor disclose any information from which Corp or plc's identity could reasonably be inferred, until such time as the information is in the public domain or Corp or plc (as appropriate) agree that the Prospective Supervisors or Supervisors may do so in writing. Clause 32: The Prospective Supervisors and Supervisors' liability to Corp and plc in connection with this engagement for direct losses shall each be limited, on the basis set out in the General Terms of Business, to a maximum aggregate of L15 million. Clause 37: In the event of a material breach of the Prospective Supervisors or Supervisors' payment terms, the Prospective Supervisors or Supervisors (as the case may be) may terminate the engagement immediately at their discretion. Clause 44: This clause (which relates to "regulated activities" under the Financial Services and Markets Act 2000) will not apply to Corp or plc as the Prospective Supervisors or Supervisors' work will not include "regulated activities" under the Financial Services and Markets Act 2000. Where and to the extent that any provision of the Supervisors' Engagement Letter (as defined in the Corp or plc Scheme as applicable) or the general terms of business conflicts with a provision of the Corp and/or plc Scheme, the provisions of the relevant Scheme shall prevail. However, in respect of the liability of the Supervisors to Corp and plc (but not, for the avoidance of doubt, between the Supervisors and the Scheme Creditors), howsoever arising, the terms of the Supervisors' Engagement Letter and the general terms of business shall prevail over any conflicting provisions of the relevant Scheme. A. The detailed scope of the work the Prospective Supervisors will perform in respect of each of the proposed Schemes is as follows: 1.1 In order that a distribution can be made to as many creditors as possible in accordance with the proposed terms of the Schemes on the Effective Date, it will be necessary for Scheme Claims Forms to be received by the Prospective Supervisors before the relevant Scheme is sanctioned. The work necessary to agree these claims (where it is possible and practicable so to do) will also have to be completed before the Court hearing to sanction the relevant Scheme by the Prospective Supervisors. 1.2 The Prospective Supervisors will receive Claim Forms from potential Scheme Creditors and maintain a list of Scheme Claims received. To the extent that Reserve Claims are received, details of such claims will be promptly communicated to the relevant Scheme Company. 1.3 Following receipt of a Claim Form, the Prospective Supervisors will use reasonable endeavours to determine promptly whether and if so, the extent to which, a Scheme Claim will be Admitted and, if so, to promptly Admit that Scheme Claim. 1.4 Following receipt of a Claim Form the Prospective Supervisors will establish (to the extent practicable in the time) the amount, if any, of the Scheme Claim and Admit the Scheme Claims at this quantum following the principles used in a liquidation under the Insolvency Act 1986, as more fully described in 922

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 24: SUMMARY OF TERMS OF APPOINTMENT AND SCOPE OF THE ENGAGEMENT OF THE PROSPECTIVE SUPERVISORS AND THE SUPERVISORS -------------------------------------------------------------------------------- the relevant Scheme. In this regard the Prospective Supervisors will consult with the relevant Scheme Company and request and receive assistance in establishing the appropriate level of claim. 1.5 Should further information be required to determine the quantum, if any, of a Scheme Claim to be Admitted, the Prospective Supervisors will request this from the Scheme Creditor. 1.6 The Prospective Supervisors will inform the Scheme Creditor whether its Scheme Claim has been Admitted and the Prospective Supervisors will, in the case of a Scheme Claim which is rejected in whole or in part provide the Scheme Creditor with written reasons for the rejection. Such a notification can only be informal unless and until the Prospective Supervisors are formally appointed as Supervisors. 1.7 In relation to Bondholders, the Prospective Supervisors will only be required to agree the claims of the respective Trustees. The Prospective Supervisors will not be required to provide details beyond this, which will be dealt with directly between the Escrow Agent, the Distribution Agent and Bondholder Communications Group. The Supervisors will, however, maintain records of Scheme Creditors based on information contained in Claim Forms and supplied to them by Bondholder Communications for the purposes of future meetings of Scheme Creditors. 1.8 The Prospective Supervisors will provide a helpline which creditors may contact with their queries about completing Forms of Proxy or Claim Forms in relation to the Scheme. 1.9 The Prospective Supervisors will acknowledge receipt of Forms of Proxy and Claim Forms. For the avoidance of doubt, the Prospective Supervisors will not acknowledge Account Holder Letters or notifications by Bondholders that they will be attending the Scheme Meeting. 1.10 The Prospective Supervisors will provide confirmations to the relevant Scheme Company, in the agreed form and on the relevant dates, relating to the levels of provisions and reserves to be included in the Schemes unless the Prospective Supervisors have reason not to give the confirmations. 1.11 The Prospective Supervisors will compile a list of creditors to be Admitted on the Effective Date of the Scheme which will be produced to Court at the hearing to sanction the Schemes should the Schemes be approved at the Scheme Meeting. B. The detailed scope of the work the Supervisors will perform is as follows: 1. CORP 1.1 CLAIM AGREEMENT (a) As mentioned above, in order that a distribution can be made to as many Scheme Creditors as possible in accordance with Corp Scheme on the Effective Date of the Corp Scheme it will be necessary for Claim Forms to be received by the Prospective Supervisors before the Scheme is sanctioned. The work necessary to agree claims (where it is possible and practicable to do so) will be completed before the Court hearing to sanction the Corp Scheme by the Prospective Supervisors as mentioned above. (b) After the Effective Date the Supervisors will receive Claim Forms from potential Scheme Creditors and maintain a list of Scheme Claims received. To the extent Reserve Claims are received, details will be promptly communicated to Corp. (c) Following receipt of a Claim Form the Supervisors will use reasonable endeavours to determine promptly whether and if so, the extent to which, a Scheme Claim will be Admitted and, if so, to promptly Admit that Scheme Claim. (d) Following receipt of a Claim Form the Supervisors will establish the amount, if any, of the Scheme Claim and Admit the Scheme Claim at this quantum following the principles used in a liquidation under the Insolvency Act 1986 (UK), as more fully described in the Corp Scheme. In this, the Supervisors will consult with Corp and request and receive assistance in establishing the amount of the Scheme Claim. 923

The costs of this are a matter for the Supervisor to determine and, once so determined, shall be met in full by Corp immediately on request, including any amounts required for protection against adverse costs orders. If Corp does not pay any such amounts the Supervisors shall, in accordance with the terms of the Scheme, have the right to raise sums from the Scheme Consideration. (h) When necessary, the Supervisors will terminate the Scheme in accordance with its terms. 1.2 DISTRIBUTIONS (a) For each distribution, subject to (b) below the Supervisors will prepare a schedule of Admitted Scheme Claims and the Scheme Consideration which they are to receive, including the currency elections and ADR elections and reflecting the effect of modelled recirculation of Scheme Consideration where appropriate (each a "SCHEDULE"), and provide this to the Escrow Trustee and the Distribution Agent for payment to be made. The Supervisors will not be responsible for the actions of the Escrow Trustee and/or the Distribution Agent. The Supervisors will not make payments themselves. (b) In relation to Bondholders or Beneficial Owners, the Supervisors will only be required to provide details of the distribution to the respective Trustees.

The Supervisors will produce a Schedule in relation to each further Scheme Claim as soon as practicable after it is Admitted. (d) Following the First Initial Distribution, the Supervisors will continue to adjudicate on and Admit or reject Scheme Claims. At any time when the Supervisors, in their sole discretion, consider that a distribution is appropriate considering the expense, the Supervisors will calculate a Further Distribution in respect of all Admitted Claims and provide a Schedule to the Escrow Trustee and the Distribution Agent. (e) The Supervisors will maintain provisions against Scheme Claims made but not Admitted and a Reserve Claims Segment in the Scheme until the termination or expiry of the Waiting Period.

(f) The Supervisors will do such other things as may be necessary to give effect to the actions above and to carry out their obligations under the Scheme. 2. PLC 2.1 CLAIM AGREEMENT (a) In order that a distribution can be made to as many Scheme Creditors in accordance with the plc Scheme on the Effective Date of the plc Scheme it will be necessary for Claim Forms to be received by the Prospective Supervisors before the Scheme is sanctioned.

Having reviewed the amount of Scheme Consideration to be set aside to form the Reserve Claims Segment under the Scheme and the provisions made in respect of unliquidated or disputed Known Claims, and based on the inquiries we have made and the information we have seen we hereby confirm that we have no reason to disagree with the Company's view that the provisions for unliquidated or disputed Known Claims and the level of reserves set by the Company are sufficient in order that all Scheme Creditors with Reserve Claims and unliquidated or disputed Known Claims will receive the same level of distribution as FID Creditors in accordance with the terms of the Scheme. [Whilst we have not been advising on the issue of working capital and express no view thereon we note your reference to the sufficiency of the working capital and your confirmation that you are of the view that it will not be necessary to fund the cost of implementing the Scheme from the Scheme Consideration.](1) This letter has been prepared for the Company's sole benefit and is being provided to you on the basis that it may not be relied upon by any other person. We do not accept liability to any person other than the Company. This letter is governed by English law.

If you have any questions relating to these instructions, please contact the KPMG HELPLINE by telephoning + 44 (0)20 7694 3007 as set out on the fourth page of this document. General 1. You are a Scheme Creditor if you held a Scheme Claim in respect of Corp or plc or both at the Record Date (5.00 p.m. London time on 27 March 2003). For example, these include banks, landlords, certain trade creditors and those with the benefit of a guarantee or warranty from Corp or plc. 2. In addition to being a Scheme Creditor, you may also be a person with an interest in Bonds. If so, please also refer to Appendix 28 and also take the appropriate action described there. 3. The Law Debenture Trust Corporation p.l.c., as trustee for the Eurobonds, and The Bank of New York, as trustee for the Yankee Bonds, are entitled to, and will, each complete a Claim Form in respect of the Corp Scheme and the plc Scheme respectively. Separate arrangements have been made for the Definitive Holder of the Bonds to vote at, or to give instructions as to how their votes should be cast in relation to, the relevant Scheme Meetings (see Appendix 28). This document 4. You have received this document (and its accompanying Form(s) of Proxy (coloured yellow for Corp Scheme Creditors and coloured green for plc Scheme Creditors) and Claim Form(s) (coloured blue for Corp Scheme Creditors and coloured pink for plc Scheme Creditors)) from Corp or plc as appropriate. Completing and Submitting your Claim Form 5. The Claim Form should be completed and signed in accordance with the guidance notes set out in it. 6. The Claim Form is printed on carbon copy paper, meaning that by writing on the top sheet of each page a duplicate copy will be completed automatically. You should tear off and retain the bottom sheet of each page (the copy) of the Claim Form and submit the top sheet of each page (the original) to KPMG LLP at 8 Salisbury Square, London, EC4Y 8BB England, UK, for the attention of Philip Wallace and Richard Heis. If you are submitting your completed Claim Form on a date approaching 17 April 2003, you are advised to use a courier or similar delivery service and not the ordinary post. If you are submitting your Claim Form by first class post sent from within the UK, you are recommended to allow at least three Business Days for delivery. KPMG will acknowledge, by first class post, receipt of all Claim Forms. 7. Claim Forms may be withdrawn or amended after submission by written notice to KPMG at 8 Salisbury Square, London, EC4Y 8BB, England, UK, for the attention of Philip Wallace and Richard Heis at any time prior to the issue by the Supervisors of instructions to the Escrow Trustee and the Distribution Agent to distribute Scheme Consideration in respect of the Scheme Claim set out in the Claim Form. 931

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 27: INSTRUCTIONS TO SCHEME CREDITORS -------------------------------------------------------------------------------- Effect of Claim Form 8. Your duly completed Claim Form constitutes your claim to Scheme Consideration in the relevant Scheme. If you have a Known Claim, in order to be assured of participating in the First Initial Distribution of Scheme Consideration in respect of that Known Claim on the Effective Date your duly completed Claim Form must be received by KPMG by 5.00 p.m. (London time) on the First Claim Date (being 17 April 2003), and your Known Claim must be listed in the First Initial Distribution Notice which will ensure that it is Admitted on the Effective Date. FOR THIS REASON YOU ARE URGED TO RETURN YOUR CLAIM FORM AS SOON AS POSSIBLE. Any amendment made to your Claim Form should be initialled next to the amendment by the person(s) signing the Claim Form. Claim Forms received before 5.00 p.m. (London time) on First Claim Date (being 17 April 2003), which are not listed (in whole or in part) in the First Initial Distribution Notice will not, to the extent to which such a Scheme Claim has not been so listed in the First Initial Distribution Notice, entitle participation in the First Initial Distribution. Any Scheme Claims not listed in the First Initial Distribution Notice will, if Admitted, receive an Initial Distribution as soon as practicable after they are Admitted. KPMG will return any Claim Forms which are not duly completed with a brief explanation of why they are not duly completed by first class post or, where a fax number has been provided, by fax. Voting at Scheme Meetings 9. In order to vote at the relevant Scheme Meeting(s), you should complete and sign the relevant Form of Proxy as described in paragraph 10 and submit it to KPMG on behalf of Corp or plc, as appropriate in accordance with paragraph 11 below. There are two separate Scheme Meetings and an appropriately coloured form of proxy must be lodged in respect of each Scheme Meeting relevant to you (Corp Scheme Creditors coloured yellow, and plc Scheme Creditors coloured green). Lodging a Form of Proxy in advance of the relevant Scheme Meeting does not prevent a Scheme Creditor from revoking such proxy and delivering a new Form of Proxy on the date of the Scheme Meeting or revoking such proxy and attending the Scheme Meeting in person. Completing your Form of Proxy 10. The relevant Form of Proxy should be completed in accordance with the guidance notes printed on it. In summary, you may elect either to: a. attend and vote at the relevant Scheme Meeting in person or appoint someone else as your proxy (other than the chairman of the Scheme Meeting) to attend and vote at the relevant Scheme Meeting in person on your behalf; or b. instruct the chairman of the relevant Scheme Meeting as your proxy to cast your vote in accordance with your wishes. You are recommended to appoint a proxy (either the chairman or someone else of your choice who would be willing to attend the relevant Scheme Meeting) in any event, even if you intend to attend and vote in person, in case you are unable to do so for some reason. If you do appoint a proxy and you then decide to attend and vote at the relevant Scheme Meeting in person, you will be entitled to do so. 11. The Forms of Proxy are printed on carbon copy paper, meaning that by writing on the top sheet of each page a duplicate copy will be completed automatically. You should tear off and retain the bottom sheet of each page (the copy) and submit the top sheet of each page (the original) to KPMG at 8 Salisbury Square, London, EC4Y 8BB England, UK, for the attention of Philip Wallace and Richard Heis. Lodging your Form of Proxy 12. YOUR DULY COMPLETED FORM OF PROXY SHOULD BE SENT AS SOON AS POSSIBLE TO KPMG AT 8 SALISBURY SQUARE, LONDON, EC4Y 8BB, ENGLAND, UK, FOR THE ATTENTION OF PHILIP WALLACE AND RICHARD HEIS. The recommended latest time for delivering the duly completed Form of Proxy to KPMG is 5.00 p.m. (London time) on 17 April 2003. The latest time and date by which KPMG should receive Forms of 932

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 27: INSTRUCTIONS TO SCHEME CREDITORS -------------------------------------------------------------------------------- Proxy is 12 noon (London time) on 24 April 2003. KPMG will acknowledge receipt of all Forms of Proxy received before 5.00 p.m. (London time) on 24 April 2003 by first class post or by e-mail where an e-mail address is given. If you are submitting your completed Form of Proxy on a date approaching the above dates you are advised to use a courier or similar delivery service and not the ordinary post. If you are submitting your Form of Proxy by first class post sent from within the UK, you are recommended to allow at least three Business Days for delivery. Alternatively, Forms of Proxy may be handed in at the registration desk for the Scheme Meeting and this should be done no later than one hour before the scheduled time of the relevant Scheme Meeting. Otherwise the Form of Proxy may be handed to the chairman of the relevant Scheme Meeting. Attending the Scheme Meetings 13. The Scheme Meetings will take place at the Institute of Civil Engineers, 1 Great George Street, London SW1 on 25 April 2003 at 10.00 a.m. (the Corp Scheme Meeting) and 10.15 a.m. (or as soon as possible thereafter following the conclusion or adjournment of the Corp Scheme Meeting) (the plc Scheme Meeting). You or the proxy attending the Scheme Meeting(s) on your behalf should produce your retained copy (bottom sheets) of the Form of Proxy, which KPMG acting as meeting adviser can then match against the original (top sheets) of your Form of Proxy. If you appoint the chairman of the relevant Scheme Meeting as your proxy, there is no need to take the Form of Proxy to the relevant Scheme Meeting. 14. Where your retained copy of the Form of Proxy is not produced, admittance to the Scheme Meeting will be permitted to you or your proxy on the production of proof of personal identity (for example, passport or other picture identification) and, where an individual is attending on behalf of a body corporate, evidence of authorisation to represent that body corporate (for example a valid power of attorney and/or board minutes) provided that the identity and authorisation, as appropriate, for that Scheme Creditor or proxy conforms with the details on the original Form of Proxy which has been received by KPMG in respect of such Scheme Creditor. However, Scheme Creditors are advised that admittance to Scheme Meetings in this way and delivery of Forms of Proxy to the registration desk on the date of the Scheme Meetings will be subject to time consuming verification at the door of the relevant Scheme Meeting. Accordingly, Scheme Creditors are recommended to submit Forms of Proxy so as to reach KPMG by 12 noon on 17 April 2003 and to bring the retained copy (bottom sheet) of the Form of Proxy to the relevant Scheme Meeting. 15. For the purposes of voting at the Scheme Meetings, to determine whether the Scheme Creditors approve the relevant Scheme by a majority in number representing 75 per cent. in value of those present and voting either in person or by proxy at that meeting the claim of a Scheme Creditor will be valued by the chairman of the relevant Scheme Meeting assisted by KPMG who will be appointed as meeting advisers to confirm, inter alia, that the statutory requisites in regard to, among other things, numerosity are adhered to. Despite the assistance of KPMG as meeting advisers the chairman of the relevant Scheme Meeting will be acting in his discretion and on information also available to him from Corp or plc as appropriate. This valuation is for voting purposes only and will not be binding for the purposes of admission of a Scheme Creditor's claim or calculating a Scheme Creditor's entitlement to Scheme Consideration under the relevant Scheme(s), which will be determined by the Prospective Supervisors and/or Supervisors based on the details provided in the Scheme Creditor's Claim Form. 16. The chairman of the relevant Scheme Meeting will have absolute discretion to admit claims, in whole or in part, for voting purposes at that Scheme Meeting only. In exercising that discretion the chairman will follow the principles set out below: a. if a claim is unascertained, contingent or disputed (in part) but the chairman is able to place a minimum value on that claim, the chairman will admit the claim for voting purposes for that minimum value; 933

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 27: INSTRUCTIONS TO SCHEME CREDITORS -------------------------------------------------------------------------------- b. if a claim is disputed in its entirety, whether it is a liquidated or unliquidated claim, that claim will not be admitted for voting purposes. Where the chairman rejects a claim in whole or in part he will notify the creditor of his decision in writing prior to the relevant Scheme Meeting where practicable, or otherwise at the Scheme Meeting, of his decision to reject that claim (in whole or in part). The chairman will report to the Court, at the hearing to sanction the relevant Scheme (which is anticipated will take place on 12 and 13 May 2003) his decision to reject claims (if any) with details of those claims and the reasons for rejection. 17. For the purposes of voting at the Scheme Meetings and determining whether or not the statutory majorities of creditors voting at those meetings are achieved claims will be converted, if appropriate, into sterling. The rate of exchange used for this purpose will be the Voting Rate. Proposal for membership of the Creditors' Committee 18. If you are willing to act as a member of the Creditors' Committee you may propose yourself to act as a member of the Creditors' Committee by ticking Box 4 on the Claim Form. On the Effective Date, the Supervisors will, to the extent possible, appoint up to seven members of the Creditors' Committee selected from those Scheme Creditors (including Definitive Holders) who have proposed themselves to act, representing a proper balance of interests of Scheme Creditors as a whole. If fewer than three Scheme Creditors (including Definitive Holders) propose themselves to act as a member of the Creditors' Committee, then on and from the Effective Date the Creditors' Committee will consist of as many members as have proposed themselves to act. In accordance with the terms of the Scheme those members, if any, will endeavour to fill the vacancy or vacancies to ensure that the Creditors' Committee has a minimum of three members within 28 days of the Effective Date. If those members do not succeed in appointing the necessary number of further members of the Creditors' Committee, resulting in a Creditors' Committee consisting of less than three members by 28 days after the Effective Date, the Supervisors will thereafter use reasonable endeavours to appoint the necessary number of further members within the following 14 days as interim committee members to serve on the Creditors' Committee until the necessary number of further permanent members are appointed. Further copies 19. If you require further copies of this document (or its accompanying Form(s) of Proxy and/or Claim Form(s)), these can be obtained from KPMG by contacting the KPMG HELPLINE on +44 (0)20 7694 3007. 934

IV. APPENDICES TO THE EXPLANATORY STATEMENT -------------------------------------------------------------------------------- APPENDIX 28 INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS If you have any questions relating to these instructions, please contact Donna Martini of Bondholder Communications Group ("BONDHOLDER COMMUNICATIONS") on +44 (0) 207 236 0779 or +1 212 422 0790 or by email at dmartini@bondcom.com. INTRODUCTION 1. The following Bonds issued by Corp and guaranteed by plc are Eurobonds: E500,000,000 5.625 per cent. Bonds due 2005 E1,000,000,000 6.375 per cent. Bonds due 2010. 2. The following Bonds issued by Corp and guaranteed by plc are Yankee Bonds: US$900,000,000 7 3/4 per cent. Bonds due 2010 US$900,000,000 8 3/8 per cent. Bonds due 2030. 3. The term "SCHEME CREDITOR" is used in this Appendix in a number of different contexts and, in each context, has a different meaning in so far as the Bonds are concerned. In relation to the Bonds: a. in the context of Submitting Scheme Claims (and therefore completing Claim Forms) under both Schemes, the term, "SCHEME CREDITOR" means only the Eurobond Trustee and the Yankee Bond Trustee; and b. in the context of voting at Scheme Meetings and the right to attend Creditors' Meetings and to be nominated to the Creditors' Committee under both Schemes, the term "SCHEME CREDITOR" means only the Definitive Holders. In the context of entitlement to receive Scheme Consideration under both Schemes, the term "SCHEME CREDITOR" is only used to mean those persons who have Submitted a Scheme Claim which has been Admitted. Each Trustee is expected to Submit a Scheme Claim and each such Scheme Claim is expected to be Admitted. However, as each Trustee will, in the Escrow and Distribution Agreement, direct that any Scheme Consideration to which it becomes entitled should be distributed to Designated Recipients, in this context reference is generally made to Scheme Consideration being distributed to Scheme Creditors (other than the Trustees) and to Designated Recipients. 4. Persons with interests in Bonds may be Account Holders, Intermediaries, Bondholders, Definitive Holders and/or Designated Recipients. a. You are an Account Holder if you are recorded directly in the books of Euroclear or Clearstream, Luxembourg (in the case of the Eurobonds) or Euroclear, Clearstream, Luxembourg or DTC (in the case of the Yankee Bonds) as holding an interest in the Eurobonds or the Yankee Bonds, as the case may be, in an account with the relevant clearing system. b. You are an Intermediary if you hold an interest in Eurobonds or Yankee Bonds on behalf of another person or persons and you do not hold that interest as an Account Holder. c. You are a Bondholder if you have the ultimate economic interest in the relevant Bonds. d. You are a Definitive Holder if you are the registered holder of a Yankee Bond in definitive form or the bearer by attornment of an individual global Eurobond in bearer form. A summary of the attornment process relating to the Eurobonds is set out in paragraph 22 and this will assist you in determining whether or not you are a bearer by attornment of an individual global Eurobond. A Definitive Holder may or may not be the same person as the Bondholder in respect of any Bond. 935

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- e. You are a Designated Recipient if you are named in an Account Holder Letter as the recipient of any part of the Scheme Consideration. A Designated Recipient may or may not be the same person as a Bondholder in respect of any Bond. 5. Ancrane is the Bondholder in respect of E324,603,000 principal amount of Eurobonds and US$261,100,000 principal amount of Yankee Bonds. Ancrane will undertake, in the Escrow and Distribution Agreement, to procure that no Account Holder Letter is delivered on its behalf so that no votes may be cast by it or on its behalf at either Scheme Meeting and will, through the same Agreement, name plc as its Designated Recipient of Scheme Consideration to facilitate Distributions of Scheme Consideration under the Schemes. EUROBONDS You should read this section (paragraphs 6 to 26) if you have an interest in Eurobonds. You need not read this section if you only have an interest in Yankee Bonds. SCHEME CREDITORS 6. The Corp Scheme Creditors for the Eurobonds are: a. The Eurobond Trustee, The Law Debenture Trust Corporation p.l.c., in accordance with the promise to pay made to it in the Trust Deeds; b. For so long as any of the Eurobonds are represented by a permanent global bearer Eurobond, the common depositary for Euroclear and Clearstream, Luxembourg, as the bearer of the relevant global Eurobond; c. For so long as the Eurobonds are in individual global form and held with Euroclear and Clearstream, Luxembourg, the Definitive Holders (as the bearers by attornment of the individual global Eurobonds) and, to the extent there are no Definitive Holders, the depositary for Euroclear and Clearstream, Luxembourg as the bearer of an individual global Eurobond; and d. If any Eurobond in definitive form is held outside Euroclear and Clearstream, Luxembourg, the bearer of that definitive Eurobond (but see below). Once an Account Holder Letter has been delivered the relevant accounts within Euroclear and Clearstream, Luxembourg in which the Eurobonds the subject of that Account Holder Letter are held will be blocked. As a result, it will not be possible to withdraw Eurobonds in definitive form from those accounts. If any Eurobonds are withdrawn from an unblocked account and, under the terms of the Eurobonds, this is only permitted on at least 60 days' notice if there has been an event of default or certain other limited events have occurred, it will not be possible to complete an Account Holder Letter in respect of those Eurobonds and they will need to be re-deposited into Euroclear or Clearstream, Luxembourg before an Account Holder Letter can be filed (and thus an entitlement to receive Scheme Consideration can arise) in respect of them. 7. The plc Scheme Creditors for the Eurobonds are: a. The Eurobond Trustee as recipient of the guarantee given by plc in the Trust Deed; and b. The Definitive Holders following execution of the Bondholder Confirmation Letter. CLAIMS IN RESPECT OF THE EUROBONDS 8. As indicated above, the Eurobond Trustee is a Scheme Creditor in respect of both the Corp and the plc Schemes. As a result, and also reflecting the fact that individual global Eurobonds are not expected to be issued until after the First Claim Date (which is shortly before the Scheme Meetings), one Claim Form under each Scheme in respect of all the Eurobonds will be completed and filed by the Eurobond Trustee on or before 5.00 p.m. (London time) on the First Claim Date on behalf of all Bondholders in respect of the Eurobonds and no other claim by a Scheme Creditor in respect of the Eurobonds will be admitted. As 936

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- claimant, the Eurobond Trustee will, in the Escrow and Distribution Agreement, direct that Scheme Consideration in respect of the Eurobonds should be paid to Designated Recipients. 9. ACCORDINGLY, NO PERSON WITH AN INTEREST IN THE EUROBONDS MAY BE OR IS REQUIRED TO COMPLETE ANY CLAIM FORM IN RESPECT OF EITHER SCHEME. HOWEVER, UNDER BOTH SCHEMES NO SCHEME CONSIDERATION (OTHER THAN CASH PAID IN RESPECT OF THE EUROBONDS) WILL BE DISTRIBUTED UNLESS: (I) CUSTODY INSTRUCTIONS (AS DEFINED IN PARAGRAPH 13 BELOW) WITH RESPECT TO THAT ACCOUNT HOLDER LETTER HAVE BEEN DULY SUBMITTED AND (II) A DESIGNATED RECIPIENT HAS BEEN DULY IDENTIFIED IN AN ACCOUNT HOLDER LETTER (IN OR SUBSTANTIALLY IN THE FORM SET OUT AS THE ANNEX TO THIS APPENDIX 28) WHICH HAS BEEN DULY COMPLETED BY AN ACCOUNT HOLDER. These instructions contain important guidance and information which should be carefully considered by Account Holders when completing their Account Holder Letters and by Bondholders and Intermediaries when giving instructions to their Account Holders to complete such letters. REQUIREMENT FOR AN ACCOUNT HOLDER LETTER 10. The Initial Distribution of Scheme Consideration under each Scheme comprises cash, New Shares and New Notes. To the extent that an Initial Distribution of the Scheme Consideration comprises cash, it will be distributed through Euroclear and Clearstream, Luxembourg in the manner described in paragraph 11 below. To the extent that an Initial Distribution of Scheme Consideration comprises New Shares or New Notes, it will be distributed to Designated Recipients in the manner identified in the relevant Account Holder Letter. In order to receive that part of the Initial Distribution of Scheme Consideration which comprises New Shares and New Notes, each Account Holder with Eurobonds credited to its account at Euroclear or Clearstream, Luxembourg must obtain whatever information or instructions it may require to enable it to deliver a duly completed Account Holder Letter on behalf of the Bondholder in respect of those Eurobonds in the manner described in paragraph 12 below. Each Account Holder Letter delivered will apply to both Schemes so that each Account Holder will only be required to complete one Account Holder Letter for each Bondholder that it represents. 11. The First Initial Distribution of Scheme Consideration is expected to be made under each Scheme on the Effective Date of that Scheme. Cash forming part of the First Initial Distribution under each Scheme will be credited to the respective Account Holders with Euroclear and Clearstream, Luxembourg which have Eurobonds credited to their accounts at the date of distribution. It is the responsibility of the Account Holders to direct payment of these funds to the appropriate recipient and none of the Escrow Trustee, the Distribution Agent, the Eurobond Trustee, Bondholder Communications or any other person shall have any responsibility for payments by Account Holders which will be dealt with in accordance with each Account Holder's existing arrangements with Bondholders and Intermediaries. 12. New Shares and New Notes forming part of the Initial Distribution under each Scheme and the cash, New Shares and New Notes forming Further Distributions will be distributed to Designated Recipients in accordance with the instructions set out in the Account Holder Letter that each Account Holder must deliver to Bondholder Communications. It will be the responsibility of Account Holders to obtain from the Intermediaries and/or Bondholders on whose behalf they are acting, in accordance with the procedures established between them, whatever information or instructions they may require to identify in an Account Holder Letter a Designated Recipient to receive such Scheme Consideration and to give the confirmations required by the Account Holder Letter. To assist this process, Bondholders (through any Intermediaries, if appropriate) are strongly encouraged to contact the Account Holder through which they hold their Eurobonds to enable that Account Holder to complete an Account Holder Letter and deliver such Account Holder Letter to Bondholder Communications prior to 5.00 p.m. (New York City time) on 17 April 2003. 13. By no later than 5.00 p.m. (local time in the place of the clearing system) on the Business Day immediately prior to the day on which the Account Holder Letter is delivered to Bondholder Communications, the Account Holder will be required to "block" with the relevant clearing system the Eurobonds the subject of that Account Holder Letter by giving instructions ("CUSTODY INSTRUCTIONS") to that effect to the relevant clearing system. The procedures for doing this are described in paragraphs 46 to 937

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- 49 below. Any Account Holder Letter and Custody Instructions delivered will be irrevocable unless and until the relevant Scheme is not approved or does not become effective. Each Custody Instruction will, in addition to blocking the relevant Eurobonds, constitute an instruction to each of Euroclear and Clearstream, Luxembourg to debit the relevant Account Holder's account with the relevant Bonds and credit them to a separate non-fungible transit account within the relevant clearing system. This is necessary to enable a Definitive Holder to be eligible to vote at the Scheme Meetings. 14. By delivering the Account Holder Letter to Bondholder Communications the Account Holder confirms to Corp, plc, Bondholder Communications, the Escrow Trustee, the Distribution Agent and the Supervisors that Custody Instructions in respect of the Eurobonds which are the subject of the Account Holder Letter have been issued to the relevant clearing system with effect from or before 5.00 p.m. (local time in the place of the clearing system) on the Business Day immediately prior to the date on which the Account Holder Letter was delivered to Bondholder Communications in accordance with the normal procedures of such clearing system and after taking into account the deadlines imposed by such clearing system, instructs the relevant clearing system to transmit to Bondholder Communications the information contained within the Custody Instructions, and gives the other confirmations required by the Account Holder Letter. 15. RECOMMENDED DEADLINE: Account Holder Letters should be delivered to Bondholder Communications (if possible, on-line through www.bondcom.com/marconi) by no later than 5.00 p.m. (New York City time) on 17 April 2003. Account Holder Letters delivered after 5.00 p.m. (New York City time) on 17 April 2003 will entitle the Designated Recipients identified in them to receipt of the New Shares and New Notes comprised in the Initial Distribution on the later of (1) as soon as is practicable following the date that the Account Holder Letter is delivered and (2) the date of the First Initial Distribution. An Account Holder Letter will be deemed delivered when actually received by Bondholder Communications, provided that if Bondholder Communications subsequently identifies any error in the Account Holder Letter or determines that an Account Holder Letter is incomplete, such Account Holder Letter will not be deemed delivered until all such errors have been rectified or the Account Holder Letter has been completed to the satisfaction of Bondholder Communications. Bondholder Communications will confirm receipt of duly completed Account Holder Letters to Account Holders who submit them. Pending receipt of such confirmation, Account Holders should contact Donna Martini of Bondholder Communications by telephone or email using the contact details given at the start of this Appendix to confirm that their Account Holder Letters have been completed to the satisfaction of Bondholder Communications. INFORMATION TO BE PROVIDED IN THE ACCOUNT HOLDER LETTER 16. Account Holders must ensure (through any Intermediaries, if appropriate) that the Bondholders in respect of the Eurobonds credited to their accounts at Euroclear or Clearstream, Luxembourg have provided them with the following information necessary to complete the Account Holder Letter: a. confirmation that the confirmations to be given by the Account Holder can be given by it on behalf of the Bondholder or its Designated Recipient (see paragraph 17 below); b. details of the account with Euroclear or Clearstream, Luxembourg to which any cash payments to be made under either Scheme to the relevant Bondholder or its Designated Recipient can be made (see paragraph 18 below); c. details of the account with DTC, Euroclear or Clearstream, Luxembourg to which New Notes to be distributed under either Scheme can be credited and in the case of the New Senior Notes distributed under each Scheme, whether such New Senior Notes are to be denominated in Euro or US dollars (see paragraph 19 below); d. details as to whether the New Shares to be distributed under either Scheme should be represented by ADRs and details as to how such New Shares or ADRs will be held (see paragraph 20 below); and e. certain voting instructions as described in paragraphs 21 through 26 below. 938

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- 17. Bondholders should read part I, Section 2, Parts D.16 and D.17 of the Scheme Document carefully. These parts describe restrictions on the distribution of securities pursuant to the Schemes under the laws of certain states of the United States and France, Italy and Malaysia (each a "RESTRICTED JURISDICTION"). Bondholders will be required to confirm to their Account Holders (through any Intermediaries, if appropriate) that they are not located in any Restricted Jurisdiction. If they are located in a Restricted Jurisdiction, Bondholders may be required to give certain additional confirmations in order to establish their eligibility to receive the New Shares and/or New Notes under applicable laws as described in part I, Section 2, Parts D.16 and D.17 of the Scheme Document. Where a required confirmation cannot be given, this should be indicated in the Account Holder Letter. In these circumstances, the Distribution Agent will sell any securities comprised in the relevant distribution of Scheme Consideration and transfer the net proceeds (after deduction of all applicable costs) to the relevant Designated Recipient (except that, where the relevant securities are not at that time listed on a securities exchange, such Designated Recipient will receive a sum in cash in sterling which is substantially equivalent in value to any such unlisted securities) by way of an individual payment of cash (as described in the final sentence of paragraph 18 below). 18. Cash comprised in the First Initial Distribution of Scheme Consideration under each Scheme will be credited to the respective Account Holders with Euroclear and Clearstream as described in paragraph 11 above. It is currently anticipated that cash comprised in any Further Distribution of Scheme Consideration under each Scheme will be distributed in the same manner. If, however, any individual Designated Recipient becomes entitled to a cash payment, it will be necessary to make individual payments through the clearing systems and therefore account details with the relevant clearing system should be provided. 19. The New Senior Notes to be distributed under each Scheme will be denominated in Euro and/or US dollars based on elections made in Claim Forms and Account Holders Letters. No New Senior Notes denominated in US dollars will be issued unless, based on information contained in all Claim Forms and all Account Holder Letters received prior to 17 April 2003, elections have been made which would, if both Schemes become effective, result in an aggregate of at least the US dollar equivalent (calculated at the Currency Rate) of Euro 250,000,000 (less the Relevant Deduction) of New Senior Notes denominated in US dollars being required to be distributed in the First Initial Distribution under both Schemes. New Senior Notes denominated in Euro will only be issued if, based on all Claim Forms and all Account Holder Letters received by 17 April 2003, elections have been made which would, if both Schemes become effective, result in an aggregate of at least Euro 250,000,000 (less the Relevant Deduction) of New Senior Notes denominated in Euro being required to be distributed in the First Initial Distribution under both Schemes. 20. The Account Holder Letter provides two options in respect of the holding of New Shares. These options are: a. delivery through a specified CREST account; and b. delivery (at the risk of the recipient) of a share certificate by ordinary uninsured mail. The New Shares to be distributed under each Scheme may be received in the form of New Shares or ADRs. An affirmative election to receive New Shares in the form of ADRs will need to be made in the Account Holder Letter if ADRs are to be delivered to the relevant Designated Recipient. Before making an election to receive ADRs, Bondholders should review the "Description of the American Depositary Receipts" in Appendix 16 to the Scheme Document, as well as the information with respect to the issuance, listing and secondary market trading of the ADRs in part I, Section 2, Parts C.2 and D.15 of the Scheme Document. In particular, persons who are considering making an election to receive ADRs should note that, although Corp will apply to list such ADRs on NASDAQ, this NASDAQ listing is currently not expected to become effective until the third calendar quarter of 2003. VOTING BY DEFINITIVE HOLDERS 21. As can be seen from paragraphs 6 and 7 above, Account Holders, Intermediaries and Bondholders are not themselves Scheme Creditors and thus are not entitled to attend or vote at Scheme Meetings. They will not become Scheme Creditors under either Scheme unless they become Definitive Holders. The terms of 939

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- the existing permanent global Eurobonds do not permit their exchange for Eurobonds in definitive bearer form unless and until an event of default under the conditions of the Eurobonds or certain other limited events have occurred. At the request of certain creditors, Corp has agreed to exchange the permanent global Eurobonds for individual global Eurobonds with a view to ensuring that persons with interests in Eurobonds can become Definitive Holders and can attend and vote at the Scheme Meetings. In light of this request, and in order to ensure parity of treatment with the Definitive Holders of the Yankee Bonds who will be entitled to attend and vote at the Scheme Meetings, Corp has requested the Eurobond Trustee to agree that the terms of the permanent global Eurobonds should be amended to permit the issuance of individual global Eurobonds at the discretion of Corp. At the request of certain creditors of plc, plc has agreed to extend the benefit of its guarantee of the Eurobonds to the Definitive Holders of Eurobonds with a view to ensuring that they can attend and vote at the plc Scheme Meetings in respect of such Bonds. 22. Pursuant to the Agreement referred to in paragraph 21, it is envisaged that each permanent global Eurobond will be exchanged for a number of individual global Eurobonds. A single individual global Eurobond will be issued in respect of each holding of Eurobonds identified in an Account Holder Letter and a further single individual global Eurobond for each series will be issued in respect of the remaining holding of Eurobonds not identified in any Account Holder Letter. Each individual global Eurobond will have the same rights as the permanent global Eurobond including the right to elect for security-printed definitive Eurobonds to be issued in certain limited circumstances. In order to make a Definitive Holder of a Eurobond a Scheme Creditor for the purposes of voting at the Corp Scheme Meeting, the benefit of the promise to pay by Corp in favour of the bearer of each individual global Eurobond must be extended to the Definitive Holder. As the Definitive Holder will not in fact be the bearer of the individual global Eurobond, this will be achieved by attornment. Accordingly, the actual bearers of the individual global Eurobonds will agree that such Bonds are held by them for the relevant Account Holders in Euroclear and Clearstream, Luxembourg and each Account Holder will agree that those of the individual global Eurobonds so attorned to him which are attributable to a particular Definitive Holder are held by him on behalf of that Definitive Holder. No attornment of any Eurobonds will be made where a Definitive Holder has not been identified in respect of those Eurobonds and, in these circumstances, the Bondholder in respect of those Eurobonds will not be entitled to attend and vote at the relevant Scheme Meetings. 23. It will, however, not be possible to issue an individual global Eurobond until the principal amount of Bonds to be represented by that individual global Eurobond has been identified in an Account Holder Letter delivered to Bondholder Communications. As a result, Corp has determined to issue the individual global Eurobonds only after 17 April 2003 (being the deadline for delivery of Account Holder Letters in order to qualify for the First Initial Distribution of Scheme Consideration under each Scheme). The Account Holder Letter will also be used to enable the Definitive Holder to vote at Scheme Meetings in the manner described below. A Definitive Holder may elect: a. to attend and vote at the Scheme Meetings in person (the procedures in this respect are described in paragraph 24); or b. to appoint a proxy (other than the chairman of the relevant meeting) to attend and vote at the Scheme Meetings on its behalf (the procedures in this respect are described in paragraph 25); or c. not to attend any Scheme Meetings but to appoint the chairman of the relevant Scheme Meeting as its proxy to vote on its behalf (the procedures in this respect are described in paragraph 26). 24. A Definitive Holder who wishes to attend and vote in person at a Scheme Meeting should ensure that this is recorded in the Account Holder Letter delivered on his behalf and that the voting intention section of the Account Holder Letter is completed, although this does not bind him to vote in any particular way at the Scheme Meeting. In order to attend a Scheme Meeting, the Definitive Holder should produce a confirmed copy of the Account Holder Letter in which he is named as the Definitive Holder which should be sent to him by Bondholder Communications. Where this copy can be matched against one of the copies provided by Bondholder Communications to KPMG, the Definitive Holder will be admitted to the relevant Scheme Meeting without further proof of identity. Where a confirmed copy of the Account Holder Letter cannot be produced by the Definitive Holder, admittance to the Scheme Meetings will be 940

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- permitted only on the production of proof of personal identity (for example, passport or other picture identification) and, where an individual is attending on behalf of a body corporate and is not the authorised employee named in the Account Holder Letter, evidence of authorisation to represent that body corporate (for example, a valid power of attorney and/or board minutes), provided that identity and authorisation, as appropriate, for that Definitive Holder conforms with the details in the relevant copy of the Account Holder Letter submitted by Bondholder Communications to KPMG. However, Definitive Holders are advised that admittance in this way will be subject to time consuming verification at the door of the relevant Scheme Meeting and, accordingly, each Definitive Holder is recommended to bring with him the copy of the Account Holder Letter which was delivered in respect of his Eurobonds. 25. A Definitive Holder who wishes to authorise Bondholder Communications to appoint a proxy (other than the chairman of the relevant meeting) to attend and vote at a Scheme Meeting on his behalf should ensure that the identity of the relevant proxy and the manner in which the proxy should vote are recorded in the Account Holder Letter in which he is named as the Definitive Holder by giving appropriate instructions to the Account Holder. The Account Holder Letter so completed will constitute authority to Bondholder Communications to complete and execute a form of proxy in the name of and on behalf of the Definitive Holder. In order to attend a Scheme Meeting the person appointed as proxy should produce a copy of the form of proxy in which he is named as proxy which will be sent to him by Bondholder Communications. Where this copy can be matched against one of the copies provided by Bondholder Communications to KPMG, the person appointed as proxy will be admitted to the relevant Scheme Meeting upon proof of personal identity (for example, passport or other picture identification). Where a copy of the form of proxy cannot be produced by the person appointed as proxy, admittance to the Scheme Meetings will be permitted only on the production of proof of personal identity (for example, passport or other picture identification), provided that identity conforms with the details in the relevant copy of the form of proxy submitted by Bondholder Communications to KPMG. However, Definitive Holders are advised that admittance in this way will be subject to time consuming verification at the door of the relevant Scheme Meeting and, accordingly, each Definitive Holder is recommended to ensure that his proxy brings with him the copy of the form of proxy which was sent to him by Bondholder Communications. Requesting that a form of proxy be completed by Bondholder Communications on behalf of a Definitive Holder does not prevent that Definitive Holder from attending and voting at the relevant meeting on production of a confirmed copy of the Account Holder Letter in which he is named as the Definitive Holder. 26. A Definitive Holder who does not wish to attend the Scheme Meetings but who wishes to authorise Bondholder Communications to appoint the chairman of the relevant Scheme Meeting as his proxy to vote on his behalf at a Scheme Meeting should ensure that this and the manner in which the chairman should vote are recorded in the Account Holder Letter in which he is named as the Definitive Holder by giving appropriate instructions to the Account Holder. The Account Holder Letter so completed will constitute authority to Bondholder Communications to complete and execute a form of proxy in the name of and on behalf of the Definitive Holder appointing the chairman of the relevant Scheme Meeting as proxy to vote on that Definitive Holder's behalf. Requesting that a form of proxy be completed by Bondholder Communications on behalf of a Definitive Holder does not prevent that Definitive Holder from attending and voting at the relevant meeting on production of a confirmed copy of the Account Holder Letter in which he is named as the Definitive Holder. YANKEE BONDS You should read this section (paragraphs 27 through 45) if you have an interest in Yankee Bonds. You need not read this section if you only have an interest in Eurobonds. SCHEME CREDITORS 27. The Corp Scheme Creditors for the Yankee Bonds are: a. For so long as any of the Yankee Bonds are represented by a global bearer Yankee Bond, The Bank of New York as Book-Entry Depositary and as Yankee Bond Trustee; and 941

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- b. For so long as any of the Yankee Bonds are in definitive registered form, the Definitive Holders (as the registered owners of the definitive Yankee Bonds). 28. The plc Scheme Creditors for the Yankee Bonds are: a. The Yankee Bond Trustee as a recipient of the guarantee given by plc in the Indenture; and b. The Definitive Holders following execution of the Bondholder Confirmation Letter. CLAIMS IN RESPECT OF THE YANKEE BONDS 29. The Bank of New York is the trustee in respect of the Yankee Bonds. Each Scheme provides that, in accordance with section 5.04 of the Indenture, The Bank of New York will file one Claim Form under each Scheme in respect of all the Yankee Bonds on or before 5:00 p.m. (London time) on the First Claim Date on behalf of all Bondholders in respect of the Yankee Bonds and that no other claim by a Scheme Creditor in respect of the Yankee Bonds will be admitted. As claimant, the Yankee Bond Trustee will, in the Escrow and Distribution Agreement, direct that Scheme Consideration in respect of the Yankee Bonds should be paid to Designated Recipients. 30. ACCORDINGLY, NO PERSON WITH AN INTEREST IN THE YANKEE BONDS MAY OR IS REQUIRED TO COMPLETE ANY CLAIM FORM IN RESPECT OF EITHER SCHEME. HOWEVER, UNDER BOTH SCHEMES NO SCHEME CONSIDERATION WILL BE DISTRIBUTED UNLESS: (I) CUSTODY INSTRUCTIONS (AS DESCRIBED IN PARAGRAPH 33 BELOW) WITH RESPECT TO THAT ACCOUNT HOLDER LETTER HAVE BEEN DULY SUBMITTED AND (II) A DESIGNATED RECIPIENT HAS BEEN DULY IDENTIFIED IN AN ACCOUNT HOLDER LETTER (IN OR SUBSTANTIALLY IN THE FORM SET OUT AS THE ANNEX TO THIS APPENDIX 28) WHICH HAS BEEN DULY COMPLETED BY AN ACCOUNT HOLDER. These instructions contain important guidance and information which should be carefully considered by Account Holders when completing their Account Holder Letters and by Bondholders and Intermediaries when giving instructions to their Account Holders to complete such letters. REQUIREMENT FOR AN ACCOUNT HOLDER LETTER 31. The Initial Distribution of Scheme Consideration under each Scheme comprises cash, New Shares and New Notes which will be distributed to Designated Recipients in the manner described in the relevant Account Holder Letter. In order to receive Scheme Consideration, each Account Holder with Yankee Bonds credited to its account at any of DTC, Euroclear or Clearstream, Luxembourg must obtain whatever information or instructions it may require to enable it to deliver a duly completed Account Holder Letter on behalf of the Bondholder in respect of those Yankee Bonds in the manner described in paragraph 32 below. Each Account Holder Letter delivered will apply to both Schemes so that each Account Holder will only be required to complete one Account Holder Letter for each Bondholder that it represents. 32. The First Initial Distribution of Scheme Consideration to Designated Recipients is expected to be made under each Scheme on the Effective Date of that Scheme. Cash, New Shares and New Notes forming part of any Distribution will be distributed to Designated Recipients in accordance with the instructions set out in the Account Holder Letter that each Account Holder must deliver to Bondholder Communications. It will be the responsibility of Account Holders to obtain from the Intermediaries and/or Bondholders on whose behalf they are acting, in accordance with the procedures established between them, whatever information or instructions they may require to identify in an Account Holder Letter a Designated Recipient to receive Scheme Consideration and to give the confirmations required by the Account Holder Letter. To assist this process, Bondholders (through any Intermediaries, if appropriate) are strongly encouraged to contact the Account Holder through which they hold their Yankee Bonds to enable that Account Holder to complete an Account Holder Letter and deliver such Account Holder Letter to Bondholder Communications prior to 5.00 p.m. (New York City time) on 17 April 2003. 33. By no later than 5.00 p.m. (local time in the place of the clearing system) on the Business Day immediately prior to the day on which the Account Holder Letter is delivered to Bondholder Communications, the Account Holder will be required to "block" with the relevant clearing system the Yankee Bonds the subject of that Account Holder Letter by giving instructions ("CUSTODY 942

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- INSTRUCTIONS") to that effect to the relevant clearing system. The procedures for doing this are described in paragraphs 46 to 51 below. Any Account Holder Letter and Custody Instructions delivered will be irrevocable unless and until the relevant Scheme is not approved or does not become effective. 34. By delivering the Account Holder Letter to Bondholder Communications the Account Holder confirms to Corp, plc, Bondholder Communications, the Escrow Trustee, the Distribution Agent and the Supervisors that Custody Instructions in respect of the Yankee Bonds which are the subject of the Account Holder Letter have been issued to the relevant clearing system with effect from or before 5.00 p.m. (local time in the place of the clearing system) on the Business Day immediately prior to the date on which the Account Holder Letter was delivered to Bondholder Communications in accordance with the normal procedures of such clearing system and after taking into account the deadlines imposed by such clearing system, instructs the relevant clearing system to transmit to Bondholder Communications the information contained within the Custody Instructions, and gives the other confirmations required by the Account Holder Letter. 35. RECOMMENDED DEADLINE: Account Holder Letters should be delivered to Bondholder Communications (if possible, on-line through www.bondcom.com/marconi) by no later than 5.00 p.m. (New York City time) on 17 April 2003. Account Holder Letters delivered after 5:00 p.m. (New York City time) on 17 April 2003 will entitle the Designated Recipients identified in them to receipt of the Initial Distribution on the later of (1) as soon as is practicable following the date that the Account Holder Letter is delivered and (2) the date of the First Initial Distribution. An Account Holder Letter will be deemed delivered when actually received by Bondholder Communications, provided that if Bondholder Communications subsequently identifies any error in the Account Holder Letter or determines that an Account Holder Letter is incomplete, such Account Holder Letter will not be deemed delivered until all such errors have been rectified or the Account Holder Letter has been completed to the satisfaction of Bondholder Communications. Bondholder Communications will confirm receipt of duly completed Account Holder Letters to Account Holders who submit them. Pending receipt of such confirmation, Account Holders should contact Donna Martini of Bondholder Communications, by telephone or email using the contact details given at the start of this Appendix to confirm that their Account Holder letters have been completed to the satisfaction of Bondholder Communications. INFORMATION TO BE PROVIDED IN THE ACCOUNT HOLDER LETTER 36. Account Holders must ensure (through any Intermediaries, if appropriate) that the Bondholders in respect of the Yankee Bonds credited to their account at DTC, Euroclear or Clearstream, Luxembourg have provided them with the following information necessary to complete the Account Holder Letter: a. confirmation that the confirmations to be given by the Account Holder can be given by it on behalf of the Bondholder or its Designated Recipient (see paragraph 37 below); b. details of the account with DTC, Euroclear or Clearstream, Luxembourg to which any cash payments under either Scheme to be made to the Designated Recipient can be made (see paragraph 38 below); c. details of the account with DTC, Euroclear or Clearstream, Luxembourg to which New Notes to be distributed under either Scheme can be credited and, in the case of the New Senior Notes distributed under each Scheme, whether such New Senior Notes are to be denominated in Euro or US dollars (see paragraph 39 below); d. details as to whether the New Shares to be distributed under either Scheme should be delivered in the form of ADRs and details as to how such New Shares or ADRs should be delivered (see paragraph 40 below); and e. certain voting instructions as described in paragraphs 41 through 45 below. 37. Bondholders should read part I, Section 2, Parts D.16 and D.17 of the Scheme Document carefully. These parts describe restrictions on the distribution of securities pursuant to the Schemes under the securities laws of certain states of the United States and of France, Italy and Malaysia (each a "RESTRICTED 943

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- JURISDICTION"). Bondholders will be required to confirm to their Account Holders (through any Intermediaries, if appropriate) that they are not located in a Restricted Jurisdiction. If they are located in a Restricted Jurisdiction, Bondholders may be required to give certain additional confirmations in order to establish their eligibility to receive the New Shares and/or New Notes under the applicable law, as described in part I, Section 2, Parts D.16 and D.17 of the Scheme Document. Where a required confirmation cannot be given, this should be indicated in the Account Holder Letter. In these circumstances, the Distribution Agent will sell any securities comprised in the relevant distribution of Scheme Consideration and transfer the net proceeds (after deduction of all applicable costs) to the relevant Designated Recipient (except that, where the relevant securities are not at that time listed on a securities exchange, such Designated Recipient will receive a sum in cash which is substantially equivalent in value to any such unlisted securities). 38. Because DTC will only clear payments in US dollars, the cash forming part of the Scheme Consideration under each Scheme (which will be paid in sterling) and any other cash comprised in the Scheme Consideration under each Scheme which is not denominated in US dollars cannot be paid to Bondholders in respect of Yankee Bonds through DTC. Accordingly, each Account Holder Letter must set out details of the DTC, Euroclear or Clearstream, Luxembourg account of the Designated Recipient to which payment of cash can be made. Where a DTC account is specified, the costs of converting the sterling or other currency into US dollars (which will be effected by the Distribution Agent at its standard quoted exchange rate) will be for the account of the Designated Recipient and will be deducted from the US dollar amount paid to him. 39. The New Senior Notes to be distributed under each Scheme will be denominated in Euro and/or US dollars based on elections made in Claim Forms and Account Holder Letters. No New Senior Notes denominated in US dollars will be issued unless, based on information contained in all Claim Forms and all Account Holder Letters received prior to 17 April 2003, elections have been made which would, if both Schemes become effective, result in an aggregate of at least the US dollar equivalent (calculated at the Currency Rate) of Euro 250,000,000 (less the Relevant Deduction) of New Senior Notes denominated in US dollars being required to be distributed in the First Initial Distribution under both Schemes. New Senior Notes denominated in Euro will only be issued if, based on all Claim Forms and all Account Holder Letters received by 17 April 2003, elections have been made which would, if both Schemes become effective, result in an aggregate of at least Euro 250,000,000 (less the Relevant Deduction) of New Senior Notes denominated in Euro being required to be distributed in the First Initial Distribution under both Schemes. 40. The Account Holder Letter provides two options in respect of the holding of New Shares. These options are: a. delivery through a specified CREST account; and b. delivery (at the risk of the recipient) of a share certificate by ordinary uninsured mail. The New Shares to be distributed under each Scheme may be received in the form of New Shares or ADRs. An affirmative election to receive New Shares in the form of ADRs will need to be made in the Account Holder Letter if a Designated Recipient is to receive ADRs. Before making an election to receive ADRs, Bondholders should review the "Description of the American Depositary Receipts" in Appendix 16 to the Scheme Document, as well as the information with respect to the issuance, listing and secondary market trading of the ADRs in part I, Section 2, Parts C.2 and D.15 of the Scheme Document. In particular, persons who are considering making an election to receive ADRs should note that, although Corp will apply to list such ADRs on NASDAQ, this NASDAQ listing is currently not expected to become effective until the third calendar quarter of 2003. VOTING BY DEFINITIVE HOLDERS 41. As can be seen from paragraphs 27 and 28 above, Account Holders, Intermediaries and Bondholders are not themselves Scheme Creditors and thus are not entitled to attend or vote at Scheme Meetings. They will not become Scheme Creditors under either Scheme unless they become Definitive Holders. The 944

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- Indenture permits the exchange of the global Yankee Bonds in whole or in part for definitive registered Yankee Bonds at Corp's discretion. At the request of certain creditors, Corp has agreed to exchange the global Yankee Bonds for definitive Yankee Bonds with a view to ensuring that persons with interests in Yankee Bonds can become Definitive Holders of the Yankee Bonds and can attend and vote at the Scheme Meetings. At the request of certain creditors of plc, plc has agreed to extend the benefit of its guarantee of the Yankee Bonds to the Definitive Holders of Yankee Bonds with a view to ensuring that they can attend and vote at the plc Scheme Meetings in respect of such Bonds. 42. It will, however, not be possible to issue a definitive registered Yankee Bond to a Definitive Holder unless and until an Account Holder Letter identifying the name of that Definitive Holder has been delivered to Bondholder Communications. As a result, Corp has determined to issue definitive registered Yankee Bonds only after 17 April 2003 (being the deadline for delivery of Account Holder Letters in order to qualify for the First Initial Distribution of Scheme Consideration under each Scheme). The Account Holder Letter will also be used for the purpose of voting at Scheme Meetings in the manner described below. A Definitive Holder may elect: a. to attend and vote at the Scheme Meetings in person (the procedures in this respect are described in paragraph 43); or b. to appoint a proxy (other than the chairman of the relevant meeting) to attend and vote at the Scheme Meetings on its behalf (the procedures in this respect are described in paragraph 44); or c. not to attend any Scheme Meetings but to appoint the chairman of the relevant Scheme Meeting as its proxy to vote on its behalf (the procedures in this respect are described in paragraph 45). 43. A Definitive Holder who wishes to attend and vote in person at a Scheme Meeting should ensure that this is recorded in the Account Holder Letter delivered on his behalf and that the voting intention section of the Account Holder Letter is completed, although this does not bind him to vote in any particular way at the Scheme Meeting. In order to attend a Scheme Meeting, the Definitive Holder should produce a confirmed copy of the Account Holder Letter in which he is named as the Definitive Holder which should be sent to him by Bondholder Communications. Where this copy can be matched against one of the copies provided by Bondholder Communications to KPMG, the Definitive Holder will be admitted to the relevant Scheme Meeting without further proof of identity. Where a confirmed copy of the Account Holder Letter cannot be produced by the Definitive Holder, admittance to the Scheme Meetings will be permitted only on the production of proof of personal identity (for example, passport or other picture identification) and, where an individual is attending on behalf of a body corporate and is not the authorised employee named in an Account Holder Letter, evidence of authorisation to represent that body corporate (for example, a valid power of attorney and/or board minutes), provided that identity and authorisation, as appropriate, for that Definitive Holder conforms with the details in the relevant copy of the Account Holder Letter submitted by Bondholder Communications to KPMG or, if no such copy has been so submitted, with the details contained in the register of Yankee Bond holders held by the Yankee Bond Trustee. However, Definitive Holders are advised that admittance in this way will be subject to time consuming verification at the door of the relevant Scheme Meeting and, accordingly, each Definitive Holder is recommended to bring with him the copy of the Account Holder Letter which was delivered in respect of his Yankee Bonds. 44. A Definitive Holder who wishes to authorise Bondholder Communications to appoint a proxy (other than the chairman of the relevant meeting) to attend and vote at a Scheme Meeting on his behalf should ensure that the identity of the relevant proxy and the manner in which the proxy should vote are recorded in the Account Holder Letter in which he is named as the Definitive Holder by giving appropriate instructions to the Account Holder. The Account Holder Letter so completed will constitute authority to Bondholder Communications to complete and execute a form of proxy in the name of and on behalf of the Definitive Holder. In order to attend a Scheme Meeting the person appointed as proxy should produce a copy of the form of proxy in which he is named as proxy which will be sent to him by Bondholder Communications. Where this copy can be matched against one of the copies provided by Bondholder Communications to KPMG, the person appointed as proxy will be admitted to the relevant Scheme Meeting upon proof of 945

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- personal identity (for example, passport or other picture identification). Where a copy of the form of proxy cannot be produced by the person appointed as proxy, admittance to the Scheme Meetings will be permitted only on the production of proof of personal identity (for example, passport or other picture identification), provided that identity conforms with the details in the relevant copy of the form of proxy submitted by Bondholder Communications to KPMG. However, Definitive Holders are advised that admittance in this way will be subject to time consuming verification at the door of the relevant Scheme Meeting and, accordingly, each Definitive Holder is recommended to ensure that his proxy brings with him the copy of the form of proxy which was sent to him by Bondholder Communications. Requesting that a form of proxy be completed by Bondholder Communications on behalf of a Definitive Holder does not prevent that Definitive Holder from attending and voting at the relevant meeting on production of a confirmed copy of the Account Holder Letter in which he is named as the Definitive Holder. 45. A Definitive Holder who does not wish to attend the Scheme Meetings but who wishes to authorise Bondholder Communications to appoint the chairman of the relevant Scheme Meeting as his proxy to vote on his behalf at a Scheme Meeting should ensure that this and the manner in which the chairman should vote are recorded in the Account Holder Letter in which he is named as the Definitive Holder by giving appropriate instructions to the Account Holder. The Account Holder Letter so completed will constitute authority to Bondholder Communications to complete and execute a form of proxy in the name of and on behalf of the Definitive Holder appointing the chairman of the relevant Scheme Meeting as proxy to vote on that Definitive Holder's behalf. Requesting that a form of proxy be completed by Bondholder Communications on behalf of a Definitive Holder does not prevent that Definitive Holder from attending and voting at the relevant meeting on production of a confirmed copy of the Account Holder Letter in which he is named as the Definitive Holder. ALL BONDS You should read this section (paragraphs 46 to 58) whether you have an interest in Eurobonds, Yankee Bonds or both Eurobonds and Yankee Bonds. PROCEDURE FOR BLOCKING BONDS HELD IN A CLEARING SYSTEM 46. All of the Eurobonds are held through Euroclear and Clearstream, Luxembourg. Certain of the Yankee Bonds are held by Account Holders in accounts with Euroclear and Clearstream, Luxembourg. Account Holders who hold Eurobonds and Yankee Bonds in an account with Euroclear or Clearstream, Luxembourg should follow the procedures for blocking their Bonds set out in paragraphs 47 to 49 below. Account Holders who are DTC Participants (other than those Account Holders who are DTC Participants with respect to Yankee Bonds held through Euroclear and Clearstream, Luxembourg) should follow the procedures for blocking their Yankee Bonds set out in paragraphs 50 and 51 below. WHERE BONDS ARE HELD THROUGH EUROCLEAR OR CLEARSTREAM, LUXEMBOURG 47. Account Holders should ensure that Euroclear and/or Clearstream, Luxembourg (as the case may be) has received irrevocable instructions (with which it has complied) to block all Bonds which are the subject of an Account Holder Letter in the securities account to which they are credited with effect from or before 5.00 p.m. (local time in the place of the clearing system) on the Business Day immediately prior to the day on which the Account Holder Letter is delivered to Bondholder Communications so that no transfers may be effected in relation to such Bonds at any time on or after such date. Bondholders procuring the submission of Account Holder Letters should instruct their Account Holders to confirm (and Account Holders should ensure) that the Account Holder Letter cross references the relevant Custody Instruction reference number. 48. Bonds held in Euroclear or Clearstream, Luxembourg should be blocked in accordance with the procedures of the relevant clearing system and the deadlines required by that clearing system. Each Custody Instruction given in respect of Eurobonds (but not Yankee Bonds) will, in addition to blocking the relevant Eurobonds, constitute an instruction to each of Euroclear and Clearstream, Luxembourg to debit the relevant Account Holder's account with the relevant Bonds and credit them to a separate non- 946

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- fungible transit account within the relevant clearing system. This is necessary to enable a Definitive Holder in respect of Eurobonds to be eligible to vote at the Scheme Meetings. 49. Bondholder Communications will request Euroclear and/or Clearstream, Luxembourg (as the case may be) to confirm to its satisfaction that any Bonds have been blocked with effect from or before the date of receipt of the Account Holder Letter. In the event that the relevant clearing system fails to do so, Bondholder Communications may reject the Account Holder Letter. In order to give the requested confirmation, Euroclear and/or Clearstream, Luxembourg (as the case may be) will need to have received its Custody Instructions no later than 5.00 p.m. (local time in the place of the clearing system) on the Business Day prior to the date on which the Account Holder Letter is submitted to Bondholder Communications. WHERE BONDS ARE HELD THROUGH DTC 50. An Account Holder which is a DTC Participant (other than those Account Holders who are DTC Participants with respect to Yankee Bonds held through Euroclear and Clearstream, Luxembourg) must, prior to 5.00 p.m. (New York City time) on the Business Day immediately prior to the date on which it delivers an Account Holder Letter, deliver Custody Instructions to DTC through ATOP for which the transaction will be eligible, and follow the procedure for book-entry transfer set forth below. A Bondholder who holds his Yankee Bonds through an Account Holder who is such a DTC Participant must contact that Account Holder (through any Intermediaries, if appropriate) to ensure that an Account Holder Letter is delivered in respect of his Yankee Bonds and Custody Instructions are given through ATOP. Utilisation of ATOP will ensure that the Yankee Bonds the subject of the Account Holder Letter are blocked for any future transfer. All such Bondholders procuring the submission of Account Holder Letters should instruct their Account Holders to confirm (and Account Holders should ensure) that the Account Holder Letter cross references the relevant VOI number allocated by DTC through its ATOP procedure. 51. Bondholder Communications must receive ATOP instructions through DTC to confirm to its satisfaction that any Yankee Bonds have been blocked with effect from or before the date of receipt of the Account Holder Letter. In the event that such ATOP instructions are not received, Bondholder Communications may reject the Account Holder Letter. In order to give the requested confirmation, an Account Holder who is a DTC participant will need to have input its Custody Instructions through ATOP no later than 5.00 p.m. (New York City time) on the Business Day prior to the date on which the Account Holder Letter is submitted to Bondholder Communications. GENERAL 52. For the purposes of voting at Scheme Meetings, to determine whether the relevant class of Scheme Creditors approve the relevant Scheme by a majority in number representing 75 per cent. in value of those present and voting either in person or by proxy at the meeting, the claim of each Definitive Holder will be valued by the chairman of the relevant Scheme Meeting assisted by KPMG who will be appointed as meeting advisers to confirm that the statutory requisites in regard to numerosity are adhered to. Despite the assistance of KPMG as meeting advisers, the chairman of the relevant Scheme Meeting will be acting in his discretion and on information also available to him from Corp or plc, as appropriate. This valuation is for voting purposes only and will not be binding for the purposes of admission of The Law Debenture Trust Corporation p.l.c.'s or The Bank of New York's claim or calculating either of their respective entitlements to Scheme Consideration under the relevant Schemes. These will be determined by the Supervisors based on the details provided in the Claim Form submitted by The Law Debenture Trust Corporation p.l.c. and The Bank of New York, respectively, and in accordance with the terms of the Schemes. 53. Each of the Eurobond Trustee and The Bank of New York is a Scheme Creditor and therefore is entitled to exercise a vote at the Scheme Meetings. If either the Eurobond Trustee or The Bank of New York were to vote this could lead to two votes being cast in respect of the same Scheme Claim if any Definitive Holders in respect of Eurobonds or, as the case may be, Yankee Bonds were also to vote. Each of the Eurobond Trustee and The Bank of New York will therefore abstain from voting at the Scheme Meetings 947

IV. APPENDICES TO THE EXPLANATORY STATEMENT APPENDIX 28: INSTRUCTIONS TO PERSONS WITH INTERESTS IN BONDS -------------------------------------------------------------------------------- because Definitive Holders will have the opportunity to vote directly, double counting issues will thereby be avoided and, in any event, neither the Eurobond Trustee nor The Bank of New York will have received any instructions as to the manner in which its votes should be cast. 54. For the purposes of voting at the Scheme Meetings and determining whether or not the statutory majorities of creditors voting at those meetings are achieved, claims will be converted into sterling. The rate of exchange used for this purpose will be the Voting Rate. 55. Bondholder Communications will use all reasonable endeavours to assist Account Holders to complete their Account Holder Letters properly, should it receive any Account Holder Letters which are not duly completed.

Every network interface card (NIC) has a DLC address or DLC identifier (DLCI) that uniquely identifies the node on the network. *DMP Distributed Multiservice Platform. DSL Digital Subscriber Line is a technology for sending digital data to customers over their existing telephone lines. There are a number of DSL variations known as xDSL, including ADSL. DSLAM Digital Subscriber Line Access Multiplexer is equipment located at a phone company's central location that links many customer DSL connections to a single high-speed ATM line. When the phone company receives a DSL signal, an ADSL modem with a POTS splitter detects voice calls and data. Voice calls are sent to the PSTN, and data are sent to the DSLAM, where it passes through the ATM to the Internet, then back through the DSLAM and ADSL modem before returning to the customer's PC. DWDM Dense Wavelength Division Multiplexing is technology that allows a single optical fibre to simultaneously carry many signals, each of which has a distinct optical wavelength closely spaced from its neighbouring channel. Fibre optics Fibre optics are thin filaments of glass through which light beams are transmitted over long distances and which carry enormous amounts of data at a High Data Speed. Fibre optic splice enclosures A casing that provides for the organisation and protection of joints made between fibre optic cable. Fibre to the curb refers to fibre optics which transmit data very close to the curb of customer residences and businesses with twisted-pair copper being used from the curb into the residences and businesses themselves.

ILEC Incumbent Local Exchange Carrier (US terminology) is the local phone company, usually one of the regional Bell operating companies or an independent telephone company. IP Internet Protocol is a method or protocol by which digital data is sent from one computer to another over the Internet. Data is sent in packets that contain the sender's unique Internet address and the receiver's unique Internet address. Individual packets traverse the network until they reach the destination address, but there is no guarantee of arrival or sequence of arrival. Another protocol, TCP, sorts the received data into correct order. ISDN Integrated Services Digital Network is an internationally agreed standard covering digital voice and data service between national networks and their connection to a home or business. ISPs Internet Service Provider -- also called internet access providers -- is a company that provides access to the Internet.

ISPs themselves are connected to one another through Network Access Points (NAPs). Mbps megabits per second or 1,000 kilobits per second. MPLS MultiProtocol Label Switching, an IETF initiative that integrates Layer 2 information about network links bandwidth, latency, utilization into Layer 3 (IP) within a particular autonomous system, or ISP, in order to simplify and improve IP packet exchange. MPLS gives network operators a great deal of flexibility to direct and route traffic around link failures, congestion, and bottlenecks. Multi-casting functionality is the ability to broadcast messages to a select group of computers or other devices when considered as part of a network. Multiplexer a system/device which combines two or more data streams into a single transmission channel. The main types are Time Division Multiplexing (TDM) where each stream has an allocated time slot, and Frequency Division Multiplexing (FDM) where each stream has an allocated channel frequency. In optical communications it is usual to refer to Wavelength Division Multiplexing (DWM) rather than FDM. Next Generation Digital Loop Carriers are the next version network transmission equipment used to provide a pair gain function where the electronic cost of the Digital Loop Carrier equipment is more than offset by additional copper distribution lines. They consist of two parts -- a central office and remote terminal. OEMs Original Equipment Manufacturers, which is a misleading term for a company that has a special relationship with computer and/or telecommunications equipment producers. OEMs buy equipment in bulk and customize them for particular applications. They then sell the customized computer under their own name. The term is really a misnomer 1012

V. DEFINITIONS AND GLOSSARY GLOSSARY -------------------------------------------------------------------------------- because OEMs are not the original manufacturers -- they are the customizers. *ONU Optical Network Units, enable premises to be served directly by fibre or by twisted-pair copper.

A protocol is a specific set of rules, procedures or conventions relating to format and timing of data transmission between two devices, typically including such things as framing, error handling, transparency and line control. Packet Switching a term used to describe the process of routing packets of data to a destination address contained within each packet. The scheme is an efficient way to handle transmission on a "connectionless" network such as the Internet because many packets from different users can share common data paths as they transverse the network. PC personal computer. PCB printed circuit board. Photonics the combination of electronic (electron) and optical (photon) technologies. It is generally associated with optical fibre systems in communications networks. *PLx photonic line system. *PMA is a reconfigurable photonic add/drop multiplexer system that provides fully reconfigurable features and functions for regional and core metropolitan network segments, allowing network operators to reconfigure network capacity in response to changes in traffic demand. *PMM is a range of photonic solutions designed specifically for metropolitan area networks.

Due to the fact solitons do not break up, spread or lose strength they are ideal for fibre optic communications networks. SONET Synchronous Optical Network. SONET is the North American and Japanese standard for synchronous transmission on an optical network. It is very similar to the European SDH standard. SONET defines a base data rate of 51.84. Megabits per second and a set of multiples of that rate. Strategic Communications The Strategic Communications business designs, manufactures and supplies communications and information systems, primarily for defence and security applications, including ground, naval, avionic, communications/command and control systems. switch a network device that selects a path or circuit for sending data or a signal to its next destination. Older technology developed for voice transmission used circuit switching to dedicate a path for the duration of a call. A modern switch in a digital network often incorporates the function of a "router" to determine specifically where each packet of data should be sent. Synchronous signals that are sourced from the same timing reference and hence are identical in frequency. *System X the Group's family of telephone exchanges which provides the majority of BT's PTSN and ISDN services.
