CERIDIAN CORPORATION ------------------ PROXY STATEMENT FOR ANNUAL MEETING OF STOCKHOLDERS TO BE HELD MAY 11, 1994 ------------------------ GENERAL INFORMATION This proxy statement and the enclosed proxy card are being mailed to stockholders beginning on or about March , 1994 in connection with the solicitation of proxies by the Board of Directors of Ceridian Corporation (the "Company") for use at the Annual Meeting of Stockholders to be held on May 11, 1994 (the "Annual Meeting"). Holders of the Company's common stock (the "Common Stock") of record at the close of business on March 22, 1994 will be entitled to vote at the meeting. At the close of business on March 22, 1994, shares of Common Stock were outstanding and entitled to vote at the meeting. Each share of Common Stock is entitled to one vote. When proxy cards are returned properly signed, the shares represented will be voted as directed. When no direction is given, the shares will be voted as recommended by the Board. The proxy also gives discretionary authority to vote the shares on any other matter which may properly come before the meeting. A stockholder may revoke a proxy at any time before it is exercised by filing a revoking instrument with the Secretary of the Company, by submitting another proxy card with a later date, or by voting in person at the meeting. The Company's Bylaws specify that except as otherwise provided by Delaware corporate law, the vote required to decide each matter to be brought before a meeting of stockholders is a majority of the shares of Common Stock represented in person or by proxy at the meeting and entitled to vote on the matter. Because shares that are held by a person who abstains from voting on a particular matter are treated as present and entitled to vote on that matter, an abstention has the same effect as a vote against the matter. If, however, a broker indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular matter, those shares will not be considered as present and entitled to vote with respect to that matter. In other words, broker non-votes are not counted against such a proposal. With respect to Item 2 to be voted on at the Annual Meeting, Adoption of Restated Certificate of Incorporation, Delaware corporate law provides that the vote required to approve that matter is a majority of all shares of Common Stock issued and outstanding. In other words, abstentions and broker non-votes have the same effect as a vote against Item 2. It is the Company's policy that all stockholder meeting proxies, ballots and voting tabulations that identify the vote of a particular stockholder are to be kept confidential if the stockholder has requested confidential treatment on the proxy card or ballot. If the stockholder so requests, no such document will be available for examination, nor will the identity and vote of any stockholder be disclosed prior to the final tabulation of the vote at the stockholders' meeting except (i) as necessary to meet applicable legal requirements; (ii) to allow the independent election inspectors to count and certify the results of the vote; or (iii) in the event of a proxy solicitation in opposition to the Board of Directors based on an opposition proxy statement filed with the Securities and Exchange Commission. The independent election inspectors may inform the Company whether or not a particular stockholder has voted. 3

ELECTION OF DIRECTORS (ITEM 1) THE BOARD OF DIRECTORS The business of the Company is managed under the direction of the Board of Directors, which met nine times in 1993. The Company's Bylaws provide that the Board shall determine the number of directors, which is currently set at eight.

Dawson Allen W. Dawson Compensation and Human Resources Committee: Ronald James Charles Marshall, Chairman Lawrence Perlman Ronald James Richard W. Vieser Richard G. Lareau Paul S. Walsh </TABLE> The Executive Committee acts on matters that arise between Board meetings and require immediate action. All actions by the Executive Committee are reported to the Board for ratification. The Executive Committee acted seven times in 1993. The Audit Committee reviews and recommends to the Board the selection of the Company's independent auditors, consults with the Company's independent auditors and reviews the scope and significant findings of the audits performed by them, reviews the adequacy and sufficiency of the Company's financial and accounting controls, practices and procedures, the activities and recommendations of its internal auditors, and its reporting policies and practices. The Audit Committee met four times in 1993. The Compensation and Human Resources Committee determines compensation policies, practices and structures for key employees of the Company, approves the compensation and benefits of executive officers, evaluates the performance of the chief executive officer, reviews the process of managing executive succession, diversity and development, and assesses the adequacy of the Company's human resource principles and philosophy. This Committee met four times in 1993. The Nominating and Board Governance Committee reviews the composition, organization and governance of the Board and its committees and recommends to the Board the adoption of policies 5

pertaining thereto, recommends to the Board compensation for non-management directors, and serves as a nominating committee that considers all nominees, including those recommended by stockholders, for Board membership. This Committee met four times during 1993. The Quality and Technology Committee reviews the systems and processes comprising the Company's quality management program, evaluates the Company's technological resources and assets, and assesses the Company's business plans and strategies in light of external technology trends and internal technological support. This Committee met three times in 1993. During 1993, each director attended at least 75 percent of the meetings of the Board and his or her committees. DIRECTORS' COMPENSATION Directors who are employees are not paid directors' fees. In 1993, directors who were not employees were paid an annual retainer of $20,000, $900 for attendance at Board meetings, $750 for attendance at committee meetings and $1,000 per day for time spent on other Company business. In addition, the chairmen of the Compensation, Audit and Quality and Technology Committees received a supplemental annual retainer of $3,000. For 1994, the fee structure and annual retainer will remain the same, but the supplemental annual retainer will be extended to the chairman of the Nominating and Board Governance Committee. Under the 1993 Non-Employee Director Stock Plan, each director who is not an employee of the Company receives a one-time grant of 1,000 shares of Common Stock, restricted as to transfer, upon election to the Board for the first time (current directors received this grant in 1993 when the Plan was approved by the Company's stockholders), and an annual grant of an option (first received during 1993) to purchase 1,000 shares of Common Stock upon election or re-election to the Board. A restricted stock award will be forfeited if the applicable director's service on the Board is terminated for any reason other than death or disability within six months from the date it was granted. Shares subject to a restricted stock award may not be sold, transferred, pledged or otherwise disposed of until such time as the director's service on the Board ceases. The exercise price per share of each option granted to a director will be 100 percent of the fair market value of the underlying Common Stock on the date the option is granted. An option will become exercisable in full six months after its date of grant, and will expire 10 years from its date of grant. Non-employee directors are also entitled to participate in a deferred compensation plan. Each such director with at least 12 calendar quarters of service as a director of the Company at the time he or she ceases to be a director will receive (or, in the event of the director's death, his or her beneficiary or estate shall receive) quarterly payments for the lesser of 48 calendar quarters or the number of quarters of service as a director. The amount of each quarterly payment will be one-fourth of the amount of the director's annual retainer at the time he or she ceases to be a director. The plan makes such payments subject to conditions involving non-competition, preservation of proprietary information and providing requested consulting services. If, within two years of a change of control of the Company (defined as described under "Executive Compensation -- Change of Control Provisions"), a director resigns following a material adverse change in the conditions under which he or she performs services as a director, or the director is removed from the Board for any reason other than conduct constituting a felony or the willful failure to fulfill duties as a director, the director will acquire a fully vested interest in any benefit accrued under this plan, even though the director may not have completed 12 calendar quarters of service as a director. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION Mr. Lareau, who served on the Company's Compensation and Human Resources Committee during 1993, is a partner in the law firm of Oppenheimer Wolff & Donnelly, which has provided and continues to provide legal representation to the Company on various matters. 6

ADOPTION OF RESTATED CERTIFICATE OF INCORPORATION (ITEM 2) INTRODUCTION On February 4, 1994, the Board of Directors unanimously deemed advisable and recommended that the Company's stockholders approve at the Annual Meeting a proposal to adopt a restated certificate of incorporation for the Company in the form attached to this proxy statement as Appendix A (the "Restated Certificate"). The description set forth below of the Restated Certificate is qualified in its entirety by the text of Appendix A, which is incorporated herein by reference. As discussed below, the Restated Certificate would amend the existing Certificate of Incorporation, as previously amended (the "Current Certificate") by: (1) Eliminating the Company's 4 1/2% Cumulative Preferred Stock ("4 1/2% Preferred Stock"), of which there are no shares issued and outstanding, from the Company's authorized capital stock; (2) Eliminating the provision which requires the Board to give due consideration to all relevant factors, including social and economic effects on employees, customers, suppliers and other constituents, in evaluating a takeover bid for the Company; (3) Eliminating the provision which provides rights beyond those provided by applicable law to holders of 25% or more of any class of capital stock to inspect the Company's books and records; and (4) Making additional minor changes generally in the interests of modernization, clarity and brevity. The Restated Certificate, which is included as Appendix A to this Proxy Statement, is being presented to the stockholders for their adoption as a single proposal. Stockholders are urged to read and consider carefully the proposed Restated Certificate. The Restated Certificate incorporates by reference the Certificate of Designation adopted by the Board in November 1993 specifying the rights and preferences of the Company's recently issued 5 1/2% Cumulative Convertible Exchangeable Preferred Stock ("5 1/2% Preferred Stock"). Because no change is being made to that Certificate of Designation, it is not included as a part of Appendix A to this Proxy Statement but is available from the Company upon request. The Board recommends that you vote FOR the adoption of the Restated Certificate. The vote required to adopt the Restated Certificate is a majority of the outstanding shares of Common Stock entitled to vote at the Annual Meeting. If the proposal to adopt the Restated Certificate is approved by the necessary vote, the Restated Certificate will become effective as of the date and time it is filed with the Secretary of State of the State of Delaware. Such filing will be made as soon as practicable following approval of the Restated Certificate by the stockholders. DESCRIPTION OF PROPOSED AMENDMENTS ELIMINATION OF 4 1/2% PREFERRED STOCK. Under the Current Certificate, the authorized capital stock of the Company consists of (i) 371,135 shares of 4 1/2% Preferred Stock, of which no shares are currently issued and outstanding; (ii) 750,000 shares of Preferred Stock, of which 50,600 shares have been designated as a series of 5 1/2% Preferred Stock and of which 47,200 shares are issued and outstanding; and (iii) 100,000,000 shares of Common Stock, of which shares were issued and outstanding as of the March 22, 1994 record date for the Annual Meeting. The Restated Certificate would eliminate the 4 1/2% Preferred Stock from the Company's authorized capital stock and delete all provisions in the Current Certificate related thereto. The Board believes the 4 1/2% Preferred Stock is obsolete and unnecessary because the Company has no plans to reissue any shares of that stock. In addition, in connection with the Company's recent public offering of 4,720,000 Depositary Shares, each representing a one one-hundredth interest in a 7

share of the Company's 5 1/2% Preferred Stock, the Company agreed with the underwriters not to issue any shares of the 4 1/2% Preferred Stock, and to use its reasonable efforts to cause the stockholders of the Company to approve an amendment to the Current Certificate to eliminate the 4 1/2% Preferred Stock from the authorized capital stock of the Company. ELIMINATION OF ARTICLE TENTH. Article Tenth of the Current Certificate provides as follows: "The Board of Directors of the Corporation, when evaluating any offer of another party to (a) make a tender offer or exchange offer for any equity security of the Corporation, (b) merge or consolidate the Corporation with another corporation, or (c) purchase or otherwise acquire all or substantially all of the properties and assets of the Corporation, shall, in connection with the exercise of its judgment in determining what is in the best interests of the Corporation and its stockholders, give due consideration to all relevant factors, including without limitation the social and economic effects on the employees, customers, suppliers and other constituents of the Corporation and its subsidiaries and on the communities in which the Corporation and its subsidiaries operate or are located." The Board recognizes that when faced with a situation which Article Tenth is meant to address, its obligation under Delaware law is to act, in the exercise of its business judgment, in the best interests of the Company and its stockholders. The Board's view is that Article Tenth, while well-intentioned, is appropriate only to the extent that it is consistent with and does not detract from the Board's overriding obligation to the Company and its stockholders. In addition, the Board wishes to avoid having a provision such as Article Tenth potentially cause any misperceptions as to the Board's view of its obligations when faced with the type of situation Article Tenth was meant to address. For these reasons, the Board has recommended the elimination of Article Tenth as part of the Restated Certificate. ELIMINATION OF SPECIAL INSPECTION RIGHT. Paragraph 3 of the General Provisions contained in Article Fourth of the Current Certificate provides that: "The books of this Corporation, including such books as show the names of the stockholders thereof, and their places of residence and the number of shares held by them, shall during the usual business hours of every business day, be open for the inspection of any person or persons holding in the aggregate twenty-five percent (25%) of any class of the outstanding capital stock." The Company has proposed to eliminate this provision in the Restated Certificate because the Company is subject to provisions of Delaware law and proxy rules adopted by the Securities and Exchange Commission (the "Commission") which collectively provide various inspection and communication rights to stockholders in certain circumstances, and which apply equally to all stockholders without regard to the size of their holdings. The Board believes that these provisions of Delaware law and of the proxy rules have struck an appropriate balance between the business needs of a corporation on the one hand, and the inspection and communication needs of stockholders on the other hand. The Board also believes it preferable to address the inspection and communication needs of all stockholders in an equitable manner, without regard to an arbitrary stockholdings threshold. The Company knows of no person or group of related persons who beneficially owns 25% or more of any class of the Company's stock. Under Section 220 of the Delaware General Corporation Law ("DGCL"), any stockholder of record of a corporation has the right, upon an appropriate written demand and during normal business hours, to inspect for any "proper purpose" (a purpose reasonably related to such person's interest as a stockholder) the corporation's stock ledger, a list of its stockholders and its other books and records. Similarly, Section 219 of the DGCL also requires that a corporation make available for inspection during normal business hours for at least ten days before any meeting of stockholders a list of stockholders, including their addresses and number of shares owned, entitled to vote at that meeting. Such list may be examined by any stockholder for any purpose germane to the meeting, and is to be made available in the city where the meeting is to be held. 8

Rule 14a-7 promulgated by the Commission under the Securities Exchange Act of 1934 imposes an obligation on any corporation subject to that Rule (including the Company) which is itself soliciting proxies in connection with a pending stockholder vote (either through a stockholders' meeting or written consent process) to either (i) provide a list of the corporation's stockholders to any record or beneficial holder of that corporation's stock who requests such a list for the purpose of sending such stockholders soliciting or communications materials relating to the pending stockholder vote, or (ii) mail to its stockholders soliciting or communications materials provided by such a stockholder relating to the pending stockholder vote. The stockholder requesting either such action must pay the costs incurred by the corporation in connection therewith, and certify that the solicitation or communication relates to the pending stockholder vote. If the Restated Certificate of Incorporation is adopted and this provision is eliminated, any person or group of persons who may, in the future, hold 25% or more of any class of the Company's stock would no longer be entitled to inspect the Company's books without a "proper purpose" under the DGCL, and would have access to the Company's stockholder list only in the circumstances outlined above under the DGCL and Rule 14a-7. OTHER CHANGES. In addition to eliminating the provisions outlined above, the Restated Certificate would make other minor, technical changes to the Current Certificate by consolidating the Current Certificate, including all existing amendments, and the proposed amendments into a single document and eliminating from that document obsolete and unnecessary provisions. These additional changes are summarized briefly as follows: (a) Eliminating a provision specifying that no stockholder of any class shall have any preemptive rights, since this is duplicative of Section 102(b)(3) of the DGCL; (b) Rephrasing a provision regarding the powers and responsibilities of the Board to track more precisely with Section 141 of the DGCL and to eliminate superfluous references to specific powers of the Board; (c) Eliminating provisions specifying the initial subscribers for the Company's capital stock and the amount of such stock with which the Company commenced business in 1912; (d) Eliminating provisions which specify that the Company is to have perpetual existence and that the private property of stockholders shall not be subject to the payment of corporate debts, since these are duplicative of Sections 102(b)(5) and (6) of the DGCL; (e) Including in the list of representative rights, powers and preferences that may be accorded by the Board to a series of Preferred Stock an expanded description of the voting rights and rights upon dissolution that may be accorded to a series of such Stock; (f) Supplementing the provisions relating to the Preferred Stock with a provision incorporating into the Restated Certificate the Certificate of Designation adopted by the Board specifying the rights and preferences of the recently issued 5 1/2% Preferred Stock; and (g) Reordering, renumbering and captioning Articles and Sections for purposes of clarity and enhanced readability. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Company's Compensation and Human Resources Committee (the "Committee"), comprised solely of non-employee directors, is responsible for establishing and administering the compensation program for the senior executive officers of the Company. The Company's executive compensation program is intended to (i) provide competitive levels of overall compensation to attract and retain well qualified executives, (ii) motivate executives to achieve the short-and long-term strategic goals of the Company and (iii) have a direct relationship to the enhancement of stockholder value. The three components in the Company's executive compensation program are base salary, annual incentive bonus and long-term incentive compensation. The program is designed so that the target mix of total 9

compensation is 40% to 60% base salary, with the balance consisting of performance-based variable components (annual incentive bonus and long-term incentive compensation). Greater weight is given to performance-based compensation at higher levels of responsibility within the Company. Information regarding competitive compensation levels and practices for positions comparable to executive officer positions within the Company is obtained by the Committee from nationwide compensation survey information collected and evaluated by independent consulting firms, and advice from an independent, nationally recognized compensation consulting firm. As a result, comparative compensation information is drawn from a broader range of companies than those included in the industry indices contained in the performance graph on page 13, and not all of the companies included in the performance graph indices are included in the surveys utilized. Based on this information, the Committee targets base salary, total cash compensation (salary plus annual bonus) and long-term incentive award levels for each executive officer position to fall in a range between the 50th and 75th percentiles of the relevant compensation marketplace. SALARY. The annual determination of an individual officer's salary within the prescribed target range is based on a subjective assessment by the Committee of the responsibilities of the position and the performance, experience and current salary of the executive filling the position. The 1993 base salary for executive officers was generally within the upper half of the targeted range. ANNUAL INCENTIVE BONUS. The annual incentive program provides yearly cash bonuses to executive officers, although the Committee may, in its discretion, permit individuals to elect to receive part or all of their annual bonus in the form of stock options rather than cash. The annual determination of an individual officer's target bonus, expressed as a percentage of base salary, is based on a subjective assessment by the Committee of the responsibilities of the position, competitive practice and the Committee's philosophy regarding performance-based compensation. For 1993, target bonus percentages for executive officers other than Mr. Perlman ranged from 35% to 55% of base salary, with the maximum possible bonus twice the target amount. Of the total potential bonus, 80% consisted of a financial component. In the case of staff officers, the financial component consisted of a requirement that the Company achieve a specified level of earnings per share ("EPS") during 1993. In the case of officers assigned to operating units, one-fourth of the financial component consisted of the same Company EPS requirement, while the balance consisted of a requirement that the operating unit achieve a specified level of pre-tax earnings ("NPBT"). The 20% non-financial component was based on the Committee's subjective assessment of the executive officer's individual performance in the areas of quality improvement and fostering workforce diversity. With respect to the financial component, bonus payments at, above or below the target percentages could be made depending on whether the financial performance of the Company (and, if applicable, the business unit to which the executive is assigned) met, exceeded or fell short of the applicable targeted financial goal. The targeted financial component of the bonus would be payable if budgeted earnings were achieved, but no financial component would be payable if an earnings threshold amount were not achieved. The Committee approved threshold and superior earnings goals above and below the target level, based on advice regarding competitive practices from the Company's compensation consultant. The Committee retains discretion to award the financial component of the annual incentive if, in its judgment, bonuses are warranted despite the failure of the Company or the business unit to achieve the minimum specified financial goal. For 1993, the Committee adjusted the financial goals that had been established at the beginning of the year so as to exclude the effect of restructuring and extraordinary charges from the Company EPS and operating unit NPBT calculations. The Committee felt that the restructuring plans adopted were necessary and in the long-term best interests of the Company and its stockholders, and that delay in adopting such restructuring plans would simply have improved 1993 financial results at the expense of longer-term financial performance. The Committee does not wish the annual incentive program to favor short-term gain at the expense of longer-term performance. Similarly, the early retirement of the Company's public debt with the proceeds of a 10

public offering of preferred stock was viewed by the Committee as a very positive development for the Company, despite the fact that early retirement of the debt entailed an extraordinary charge. Following these adjustments, both the financial and non-financial components of the 1993 annual incentive program were paid above the target level for executive officers, resulting in bonus payments for executive officers other than Mr. Perlman ranging between 52% and 82% of base salary. LONG-TERM INCENTIVES. Long-term incentives are intended to emphasize the link between executive compensation and improved long-term stock price performance. Although the Company's 1993 Long-Term Incentive Plan provides for the grant of stock options, restricted stock, stock appreciation rights and performance units, stock options with a fair market value exercise price are seen by the Committee as having a significant tie to increases in stockholder value. As a result, stock options were the sole long-term incentive utilized for executives during 1993, except for one restricted stock award made to a newly hired executive. An annual award of stock options is typically made to each executive officer, although additional awards may be made at the Committee's discretion in circumstances such as promotions. The annual determination of an individual officer's option award within the range prescribed for his or her position is based on a subjective assessment by the Committee of the responsibilities of the position and the performance and experience of, and past option awards made to, the individual. For 1993, option awards to executive officers were generally at the midpoint of the targeted range. CHIEF EXECUTIVE OFFICER COMPENSATION. Mr. Perlman's base salary during 1993 was $600,000, unchanged since 1990, and will remain at that level for 1994. While the Committee believes Mr. Perlman has performed exceptionally well, maintaining the base salary at this level was deemed appropriate to increasingly orient his total compensation toward performance-based components. Mr Perlman's 1993 annual incentive was determined based solely on the Company's EPS, and amounted to 92.5% of base salary as compared to a target of 65%, reflecting above target earnings performance for the Company during 1993, after taking into account the previously mentioned adjustments for restructuring and extraordinary charges. Mr. Perlman elected at the beginning of 1993 to receive one-third of his 1993 annual incentive in stock options, which resulted in the grant of an option to acquire 39,998 shares. For purposes of this election, an option to acquire one share was valued at one-third of the option exercise price. Mr. Perlman was granted a stock option for 100,000 shares during 1993 as the long-term incentive portion of his compensation package. In approving this award, the Committee principally considered (i) Mr. Perlman's role in the Company's improved 1993 operating performance, the successful Preferred Stock offering and 1993 strategic planning efforts, (ii) the increase in the Company's stock price during the year, (iii) the competitive range for Mr. Perlman's position and (iv) the desire to increasingly orient his compensation toward performance-based components. DEDUCTIBILITY OF EXECUTIVE COMPENSATION. During 1993, the Internal Revenue Code (the "Code") was amended to impose on public companies, such as Ceridian, an annual limit of $1 million on deductions for compensation payments made to each of the chief executive officer and the four most highly paid executive officers employed at fiscal year end. Compensation that is considered "performance-based" according to the Code is not counted toward the $1 million annual limit. The Committee supports the concept that a significant portion of the total compensation provided to an executive, particularly the chief executive officer and others occupying positions of significant responsibility within the Company, should be performance-based, and has attempted to implement and administer programs that are consistent with this concept. For example, a large component of the compensation provided to the five highest compensated officers is in the form of stock options. The Code classifies stock options granted with a fair market value exercise price as "performance-based." Although the Committee has considered amending other elements of the compensation program so they can be considered "performance-based" for purposes of the Code, the Committee believes that it is more important for it to retain the flexibility to tailor the compensation program in the manner it 11

believes most beneficial to the Company and its stockholders, than it is to qualify every aspect of the Company's executive compensation program as "performance-based" for purposes of the Code. In addition, any non-deductible amount of future compensation is not expected to be material to the Company, nor would such non-deductibility financially disadvantage the Company in any manner given the Company's tax position.

STOCK PRICE PERFORMANCE GRAPH The graph below compares the cumulative total return during the period 1989-1993 for the Company's Common Stock, the S&P 500 Index, the S&P Computer Software and Services Index and the S&P Electronics Defense Index. Although the Stock Price Performance Graph in the Company's Proxy Statement for its 1993 Annual Meeting of Stockholders also included the cumulative total return for the S&P Computer Systems Index, that Index has not been included in the graph below because that Index no longer provides a meaningful comparison for any portion of the Company since the 1992 dividend distribution by the Company to its stockholders of all of the common stock of the Company's former computer systems subsidiary, Control Data Systems, Inc. This graph assumes the investment of $100 in the Company's Common Stock, the S&P 500 Index and each of the industry indices on December 31, 1988, and the reinvestment of all dividends as and when distributed. Included in the dividends reinvested is the previously mentioned 1992 dividend distribution of the stock of Control Data Systems, Inc. For purposes of this graph, it is assumed that the shares of Control Data Systems stock were received on the September 1, 1992 ex-dividend date, sold at the closing market price on that date, and the proceeds reinvested in shares of Ceridian Common Stock at the closing market price on that date.

Under that Plan, the Compensation Committee retains discretion, subject to plan limits, to modify the terms of outstanding options, including exercisability dates. Exercisability will be accelerated upon a change of control of the Company, as defined in "Change of Control Provisions" below. (2) The per share exercise price of each option granted in 1993 is equal to the market value (closing price on the NYSE) of a share of the Company's common stock on the date of grant. (3) These amounts represent certain assumed rates of appreciation only. Actual gains, if any, on stock option exercises are dependent on the future performance of the Company's common stock, overall market conditions and the optionees' continued employment through the vesting period. The amounts represented in this table may not necessarily be achieved. (4) Option awarded in consideration of Mr. Perlman's election to receive 33 1/3% of his 1993 annual bonus in the form of a stock option rather than cash. Original option grant in February 1993 of 53,315 shares, corresponding to maximum potential bonus payment, was reduced to 39,998 shares in January 1994 upon determination of actual bonus payout. Option became fully exercisable on January 24, 1994 in connection with such determination. (5) This option becomes exercisable in cumulative 33 1/3% installments on January 1 of 1995, 1996 and 1997.

PENSION PLAN The Company maintains a voluntary, tax qualified retirement plan (the "Retirement Plan") which is funded by employee salary reduction contributions and Company contributions. The amount of the annual benefit under the Retirement Plan is based upon an employee's average annual compensation during the employee's highest consecutive five-year earnings period with the Company while participating in the Retirement Plan. Because the Internal Revenue Code limits the annual benefit that may be paid from a tax-qualified plan such as the Retirement Plan, the Company has established a Benefit Equalization Plan to provide retirees with supplemental benefits so that they will receive, in the aggregate, the benefits they would have been entitled to receive under the Retirement Plan had these limits not been in effect. The following table shows estimated annual benefits payable under the Retirement Plan and the Benefit Equalization Plan to an employee who retires in 1994 at age 65: PENSION PLAN TABLE <TABLE> <CAPTION> YEARS OF SERVICE --------------------------------------------------------------- REMUNERATION 15 20 25 30 35 - ------------- ----------- ----------- ----------- ----------- ----------- <S> <C> <C> <C> <C> <C> $ 200,000 $ 46,177 $ 61,569 $ 76,961 $ 92,353 $ 104,353 300,000 70,177 93,569 116,961 140,353 158,353 400,000 94,177 125,569 156,961 188,353 212,353 500,000 118,177 157,569 196,961 236,353 266,353 600,000 142,177 189,569 236,961 284,353 320,353 700,000 166,177 221,569 276,961 332,353 374,353 800,000 190,177 253,569 316,961 380,353 428,353 900,000 214,177 285,569 356,961 428,353 482,353 1,000,000 238,177 317,569 396,961 476,353 536,353 1,100,000 262,177 349,569 436,961 524,353 590,353 1,200,000 286,177 381,569 476,961 572,353 644,353 </TABLE> Annual compensation for purposes of the Retirement Plan and the Benefit Equalization Plan consists of salary and any annual bonus paid during the year (whether payable in cash or stock options), less the amount contributed by the employee to the Retirement Plan that year. Compensation for 1993 covered by these Plans for the Named Executives is as follows: Mr. Perlman, $1,005,142; Mr. Handberg, $623,366; Mr. Sommers, $263,485; and Mr. Turner, $323,625. Mr. Morris elected not to participate in the Retirement Plan. For purposes of the Retirement Plan and the Benefit Equalization Plan, an annual bonus is considered part of annual compensation in the year in which it is paid, rather than the year in which it was earned (which is the basis on which amounts are reported in the Summary Compensation Table). As of March 1, 1994, years of credited service for the Named Executives were as follows: Mr. Perlman, 13.76 years; Mr. Sommers, 1.31 years; and Mr. Turner, 1.18 years. Mr. Handberg retired from the Company on December 31, 1993. Benefit amounts in the Pension Plan Table are computed assuming payments are made on the normal life annuity basis and not under any of the various survivor options. Benefits listed in the table are not subject to deduction for Social Security or other offset amounts. EXECUTIVE EMPLOYMENT AGREEMENTS The Company has employment agreements with each of the Named Executives other than Mr. Handberg. The term of each of these agreements is the later of June 30, 1995 (December 31, 1998 in the case of Mr. Perlman) or two years after a "change of control" (as defined in "Change of Control 16

Provisions" below) occurring before the normal contract termination date. These agreements generally specify that the executives are required to devote full time to the Company and will be compensated in accordance with the compensation policies of the Company, and contain provisions regarding protection of confidential information, rights in any intellectual property created by the executive, and restrictions on competition. If the Company terminates an agreement without cause, the executive is entitled to receive a lump sum payment equal to two years' base salary (three years in Mr. Perlman's case). In addition, the agreement for Mr. Perlman provides that in the event of such a termination, he would receive a supplemental retirement benefit calculated by including the lump sum payment previously noted in the determination of final average pay for purposes of computing retirement benefits. Mr. Perlman's agreement additionally provides that the calculation of such supplemental retirement benefit will include three additional years of service credit. Also in the event of termination without cause, Mr. Perlman's agreement provides that his rights and benefits under any restricted stock or option plans will fully vest, and any restrictions on shares of stock received under such plans will immediately lapse. Each agreement also contains a number of change of control provisions described below under "Change of Control Provisions." CHANGE OF CONTROL PROVISIONS The payment of benefits or vesting of awards under the Company's 1993 Long-Term Incentive Plan ("1993 LTIP"), 1990 Long-Term Incentive Plan ("1990 LTIP"), and the executive employment agreements described above accelerates upon a "change of control" or a "change of control termination." For these purposes, a "change of control" is defined as (1) a merger or consolidation involving the Company if less than 50 percent of the Company's voting stock after the business combination is held by persons who were stockholders before the business combination; (2) a sale of the assets of the Company substantially as an entirety; (3) ownership by a person or group of at least 20 percent of the Company's voting securities; (4) approval by the stockholders of a plan for the liquidation of the Company; and (5) certain changes in the composition of the Company's Board of Directors. The term "change of control termination" refers to either of the following if it occurs within two years of a "change of control" of the Company: (i) termination of an executive's employment by the Company for reasons other than substantial nonperformance of duties or conduct constituting a felony involving moral turpitude; or (ii) the executive terminates employment with the Company for "good reason." "Good reason" is generally defined as an adverse change in an executive's responsibilities, authority, compensation or working conditions, or a material breach of an employment agreement by the Company. All restrictions on restricted stock held by an executive pursuant to the 1993 LTIP will immediately lapse, and all options granted under the 1993 LTIP will become exercisable immediately upon a change of control. Under the 1990 LTIP, the same results follow a change of control termination. Within 30 days following a change of control termination, a participant in the 1990 LTIP may generally require the Company to purchase any shares of stock awarded to the participant under the plan as to which restrictions on transfer lapsed because of the change of control termination. The purchase price will equal the fair market value of the shares on the day prior to the change of control. The executive employment agreements described above also provide that following a change of control termination, an executive is entitled to receive a lump sum payment that is one dollar less than three times the executive's "annualized includable compensation," which is the average annual compensation received by the executive from the Company and includable in the executive's gross income during the five most recent taxable years ending before the change of control. The agreement for Mr. Perlman provides that the amount of this lump sum payment is to be included in the determination of final average pay for purposes of computing supplemental retirement benefits. This lump sum payment would be in lieu of any other severance payment specified in an executive employment agreement. The executive employment agreements and stock based incentive plans also provide that all change of control compensation pertaining to an executive must be less than the amount which would be considered a "parachute payment" under the Internal Revenue Code. 17

The Company has established a benefits protection trust for various employees (principally executives), directors and certain retired executives of the Company. The trust agreement provides that if, following a change of control, benefits payable under any plan or agreement covered by the trust (which generally includes all executive employment agreements, benefit and incentive plans for officers and directors, and separation agreements with certain former executives) are improperly withheld by the Company from any trust beneficiary, the trustee shall, upon the request of such beneficiary, pursue the claims of the beneficiary against the Company, including the commencement of legal proceedings against the Company if necessary. The Company is obligated to reimburse the trustee for all fees and expenses incurred in connection therewith. To the extent the Company fails to do so, the trustee may pay such fees and expenses from the trust. The Company has provided initial funding of $100,000 to the trust for this purpose, and upon a threatened change of control (as defined in the trust agreement), the trustee would require the Company to provide an additional $2,900,000 of funding for this purpose. The trust agreement also provides for the establishment of an account for the payment of benefits under the Benefit Equalization Plan after a change of control.

OTHER MATTERS STOCKHOLDER PROPOSALS Any stockholder proposal to be included in the proxy materials for the 1995 Annual Meeting of Stockholders must be received by the Company on or before November , 1994. The Company's Bylaws require advance written notice to the Company of stockholder-proposed business or of a stockholder's intention to make a nomination for director at an annual meeting of stockholders. They also limit the business which may be conducted at any special meeting of stockholders to business brought by the Company's Board. Specifically, the Bylaws provide that business may be brought before an annual meeting by a stockholder only if the stockholder provides written notice to the Secretary of the Company not less than 50 or more than 75 days prior to the meeting, unless notice of the date of the meeting is given to stockholders or is publicly announced less than 65 days prior to the meeting. In that case, a stockholder's notice of proposed business must be provided no later than 15 days following the date notice of the annual meeting was mailed or the public announcement of the date was made, whichever is earlier. The Company's 1995 Annual Meeting of Stockholders will be held on May 10, 1995. A stockholder's notice must set forth (i) a description of the proposed business and the reasons therefor, (ii) the name and record address of the stockholder proponent, (iii) the class and number of shares of Company stock owned by the stockholder and (iv) a description of any material interest of the stockholder in the proposed business. The Bylaws also provide that a stockholder may nominate a director at an annual meeting only after providing advance written notice to the Secretary of the Company within the time limits described above. The stockholder's notice shall set forth all information about each nominee that would be required under Securities and Exchange Commission ("SEC") rules in a proxy statement soliciting proxies for the election of such nominee, as well as the nominee's business and residence address. The notice must also set forth the name and record address of the stockholder proponent and the class and number of shares of Company stock owned by the stockholder proponent. COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT Section 16(a) of the Securities Exchange Act requires the Company's directors, executive officers and persons who beneficially own more than 10% of the Company's common stock to file with the SEC reports of ownership regarding the common stock and other equity securities of the Company. These 20

persons are required by SEC regulation to furnish the Company with copies of all Section 16(a) reports they file. To the Company's knowledge, based on a review of the copies of such reports furnished to the Company during the period January 1, 1993 to February 14, 1994, all Section 16(a) filing requirements applicable to its officers, directors and 10% beneficial owners were complied with, except that Ronald L. Turner filed his Initial Statement of Beneficial Ownership on Form 3 one day late due to business travels. SOLICITATION OF PROXIES The cost of soliciting proxies will be borne by the Company. The Company has retained Georgeson & Company, New York, New York, to aid in solicitation of proxies. The fees and expenses of Georgeson & Company are estimated at $20,000. Officers and employees of the Company may solicit proxies by further mailings, by telephone and telegraph, and by personal conversations. No special compensation will be paid to such persons for these tasks. The Company may reimburse brokerage firms and others for their expenses in forwarding solicitation material to the beneficial owners of the stock entitled to be voted at the meeting.
