2.4 Exercise of Option.

(a) Buyer shall have the right to exercise the Option at any time from the date hereof through the expiration of the Option Period and as provided in Section 11.2.

3.5 Procedures for Assignments.

(a) Notwithstanding anything to the contrary contained herein, this Agreement shall not constitute an agreement to assign or transfer any Acquired Asset (or right, benefit or obligation thereunder or resulting therefrom) if an assignment or transfer thereof, without the Consent of a Person, would constitute a breach or violation thereof and such Consent is not obtained at or prior to the Closing.

To the extent that any such Acquired Asset cannot be transferred or the full benefits and burdens of use of any such Acquired Asset cannot be provided to Buyer following the Closing pursuant to this Section 3.5, then Buyer and Seller shall enter into such arrangements (including subcontracting) to provide to the Parties the economic (considering Tax costs and benefits) and operational equivalent, to the extent permitted, of obtaining such Consent. Seller shall hold in trust for and pay to Buyer promptly upon receipt thereof, all income, proceeds and other monies received by Seller or any of its Affiliates in connection with the use of any Acquired Asset in connection with the arrangements under this Section 3.5. To the extent that Buyer is provided the benefits and burdens of any Acquired Asset or right, benefit or obligation thereunder or resulting therefrom referred to herein (whether from Seller or otherwise) as if the appropriate Consent had been obtained, Buyer shall discharge and perform the Liabilities of Seller thereunder or in connection therewith, as applicable, to the same extent as if the appropriate Consent had been obtained.

The foregoing right of audit may be exercised only once during any [***] period, except in the event that a previous audit during such [***] period detected any material inaccuracies in payments, in which case, Seller may exercise its right of audit once more during [***] to confirm that such inaccuracies have been corrected. The auditing Independent Accountant may be required by Buyer or its Affiliates to enter into a reasonably acceptable confidentiality agreement, and in no event shall such Independent Accountant disclose to Seller or its Affiliates any information other than such as relates to the accuracy of reports and payments made or due hereunder. The opinion of such Independent Accountant regarding such reports, accountings and payments shall be binding on the Parties.

-53-

(e) The right of Buyer to indemnification pursuant to Section 12.2 will not be affected by any investigation conducted or knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to any accuracy of any representation or warranty, or performance of or compliance with any covenant or agreement herein. [***].

12.3 Indemnification by Buyer.

-54-

(d) Other than in the case of Fraud with respect to the representations and warranties made by Buyer in this Agreement or the certificate delivered by Buyer pursuant to Section 10.2(c)(ii), the cumulative indemnification obligations of Buyer under Sections 12.3(a)(i) and 12.3(a)(ii) (other than in the case of [***]) shall in no event exceed, in the aggregate, [***]. To the extent that Seller or any other Seller Indemnified Party is not able to recover any Losses resulting from any such breach solely as a result of the limitation in the immediately preceding sentence, and the aggregate of the amount actually received by and the amount due and payable (but not yet paid) to Seller under this Agreement subsequently increases, then the amount of any such unrecovered Losses for such breach shall be recoverable up to the amount of such increase; provided, that, for clarity, this sentence shall not extend the applicable survival period under Section 12.1.

(e) The right of Seller to indemnification pursuant to Section 12.3 will not be affected by any investigation conducted or knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to any accuracy of any representation or warranty, or performance of or compliance with any covenant or agreement herein. [***].

12.4 Third Party Claims.

(a) In the event that any Claim for which Buyer or Seller (an “Indemnifying Party”) may have Liability to any Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a Third Party (a “Third Party Claim”), Buyer (on behalf of any Buyer Indemnified Party) or Seller (on behalf of any Seller Indemnified Party), as applicable, shall promptly, but in no event more than [***] following such Indemnified Party’s receipt of a Third Party Claim, notify the Indemnifying Party in writing of such Third Party Claim, the amount or the estimated amount of damages sought under such Third Party Claim to the extent then ascertainable (which amount shall not be conclusive of the final amount of such claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”); provided, however, that the failure to timely give a Claim Notice shall affect the rights of an Indemnified Party hereunder only to the extent that such failure has an actual and materially prejudicial effect on the defenses or other rights available to the Indemnifying Party with respect to such Third Party Claim.

(b) The Indemnifying Party shall have the right, at its option and expense, to defend the Indemnified Party in connection with any Third Party Claim and direct and control such defense with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party provided, however, that the Indemnifying Party may not assume control of the defense of any Third Party Claim (i) involving any criminal proceeding, action, indictment, allegation or investigation, or in which relief other than monetary damages is sought, (ii) involving the alleged misuse, infringement, misappropriation or violation of any Intellectual Property, (iii) involving a purported class action, (iv) if the Indemnifying Party has not notified the Indemnified Party in writing that it will be liable to indemnify the Indemnified Party with respect to all Losses relating to such Third Party Claim, subject to the limitations of Section 13.2 or Section 13.3, as applicable, or (v) if the Third Party Claim relates to a Proceeding by any Regulatory Authority with respect to the Compound or any Product. In addition, the Indemnifying Party may not maintain the defense of a Third Party Claim if it has failed to defend such Third Party Claim in good faith. If the Indemnifying Party elects to defend the Indemnified Party against a Third Party Claim, it shall within [***] after its receipt of the applicable Claim Notice (or sooner, if the nature

-55-

of the Third Party Claim so requires) notify the Indemnified Party of its intent to do so. Once the Indemnifying Party has assumed the defense of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing at its own cost and expense; provided, however, that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party if (A) so requested by the Indemnifying Party to participate, (B) in the reasonable opinion of outside counsel to the Indemnified Party a conflict or potential conflict exists between the Indemnified Party and the Indemnifying Party that would make such separate representation advisable, or (C) in the reasonable opinion of outside counsel to the Indemnified Party there are legal defenses available to the Indemnified Party that are different from or additional to those available to Indemnifying Party; and provided, further, that the Indemnifying Party shall not be required to pay for more than one such counsel (plus any appropriate local counsel) for all Indemnified Parties in connection with any Third Party Claim. If after assuming the defense of a Third Party Claim the Indemnifying Party determines that it is not required to provide indemnification therefor, it shall promptly notify the Indemnified Party, cease to control the defense of such Third Party Claim, and shall nonetheless be responsible for all costs of defense incurred by it prior to such notice. Neither the Indemnifying Party nor the Indemnified Party shall, without the written consent of Buyer (on behalf of any Buyer Indemnified Party) or Seller (on behalf of any Seller Indemnified Party), as applicable, settle or compromise any Third Party Claim or permit a default or consent to entry of any Order unless (1) the claimant provides to such other party an unqualified release of the Indemnified Parties and Indemnifying Parties from all liability in respect of such Third Party Claim, (2) such settlement does not involve any injunctive relief binding upon the Indemnified Party or any of its Affiliates, (3) such settlement does not encumber any of the material assets of any Indemnified Party or impose any restriction or condition that would apply to or adversely affect any Indemnified Party or the conduct of any Indemnified Party’s business and (4) such settlement does not involve any admission of liability or wrongdoing or violation of Law by any Indemnified Party or any of its Affiliates.

(c) If the Indemnifying Party elects not to defend the Indemnified Party against a Third Party Claim, or is not permitted to assume the defense of a Third Party Claim pursuant to Section 12.4(b), the Indemnified Party shall have the right but not the obligation to assume its own defense, it being understood that any right of the Indemnified Party to indemnification for a Third Party Claim shall not be adversely affected by assuming the defense of such Third Party Claim.

(d) The Indemnified Party and the Indemnifying Party shall reasonably cooperate in order to ensure the proper and adequate defense of a Third Party Claim. The Indemnified Party and the Indemnifying Party shall keep each other fully informed with respect to the status of such Third Party Claim.

(e) The Indemnified Party and the Indemnifying Party shall use commercially reasonable efforts to avoid production of confidential information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third Party Claim to be made so as to preserve any applicable attorney-client or work-product privileges.

-56-

12.5 Direct Claims.

(a) If an Indemnified Party wishes to make a claim for indemnification hereunder for a Loss that does not result from a Third Party Claim (a “Direct Claim”), Buyer (on behalf of any Buyer Indemnified Party) or Seller (on behalf of any Seller Indemnified Party), as applicable, shall notify the Indemnifying Party in writing of such Direct Claim, the amount or the estimated amount of damages sought with respect to such Direct Claim to the extent then ascertainable (which amount shall not be conclusive of the final amount of such claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto; provided, however, that the failure to give such a claim notice shall affect the rights of an Indemnified Party hereunder only to the extent that such failure has an actual and materially prejudicial effect on the defenses or other rights available to the Indemnifying Party with respect to such claim.

(b) The Indemnifying Party shall have a period of [***] within which to respond to such Direct Claim. If the Indemnifying Party does not respond within such [***] period, the Indemnified Party shall provide a second notice and if Indemnifying Party does not respond to such second notice within [***], will be deemed to have accepted the Direct Claim. If the Indemnifying Party rejects all or any part of the Direct Claim, the Indemnified Party shall be free to seek enforcement of its rights to indemnification under this Agreement with respect to such Direct Claim.

12.6 Set-Off(a) . In addition to all other remedies contemplated herein, subject to Section 12.2, Buyer shall have the right and option (but not the obligation) to set-off against and deduct from any Deferred Fixed Payment or Deferred Variable Payment that becomes due and payable hereunder the amount of Losses relating to any indemnification claim made by a Buyer Indemnified Party finally determined to be recoverable under this Agreement with respect to such claim.

12.7 Adjustment to Losses.

(a) [***]. [***].

(b) [***]. [***].

(c) [***]. [***].

12.8 Characterization of Indemnification Payments. Except as otherwise required by applicable Law, all payments made by an Indemnifying Party to an Indemnified Party in respect of any claim pursuant to Section 12.2 or Section 12.3 shall be treated as adjustments to the Purchase Price for all applicable Tax purposes.

12.9 Exclusive Remedy. Subject to Section 13.10, and except as otherwise expressly provided in this Agreement (including disputes under Section 1.1 (Net Sales), which are to be resolved pursuant to the procedures set forth in Schedule 1.1(A)), the Parties acknowledge that their sole and exclusive monetary remedy after the Closing with respect to any claims relating to, arising under, or resulting from this Agreement, and the sole and exclusive monetary remedy available to any Buyer Indemnified Party or Seller Indemnified Party after the Closing with respect

-57-

to any claims relating to, arising under, or resulting from this Agreement, shall be pursuant to the indemnification provisions set forth in this Article XII. The foregoing shall in no way limit (a) the remedies available to any Party in the case of Fraud or any Person under any Ancillary Agreement or (b) the rights of a Party to seek equitable remedies (including specific performance or injunctive relief) or any remedies available to it under applicable Law in the event of a Party’s failure to comply with its indemnification obligations hereunder.

12.10 Satisfaction of Indemnification Claims. Subject to the rights of Buyer set forth in Section 12.6, Buyer or Seller, as applicable, shall pay the amount of any indemnification claim for which it agrees it is liable, or that has been finally determined to be owing by a court of competent jurisdiction or an arbitral body, in each case in accordance with this Agreement, and which has not otherwise been satisfied in accordance with this Agreement, by wire transfer of funds within 30 days after such agreement or determination.

ARTICLE XIII

MISCELLANEOUS

13.1 Assignment.

(a) Except as provided in Section 13.1(b), this Agreement may not be assigned or transferred by either Party in whole or in part, nor may any Party assign or transfer any rights or obligations created by this Agreement, without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed.

(b) Buyer may assign or transfer this Agreement, or any rights or obligations hereunder in whole or in part, to (i) one or more of its Affiliates, (ii) its successor in interest in connection with any sale, license or other disposition of all or substantially all of that portion of its business pertaining to the subject matter of this Agreement or (iii) as contemplated under Section 3.8(e); provided, however, that in the case of the foregoing clause (i), Buyer remains liable and responsible to Seller for the performance of its obligations hereunder and in the case of the foregoing clause (ii) such transferee assumes those obligations in writing. Seller may assign or transfer this Agreement and all of its rights and obligations hereunder in whole (but not in part) to its successor in interest in connection with a Liquidation Event permitted hereunder; provided, however, that such transferee assumes those obligations in writing.

(c) Subject to Section 13.1(a) and Section 13.1(b), the terms of this Agreement will be binding upon and will inure to the benefit of the successors, heirs, administrators and permitted assigns of the applicable Party. Any purported assignment in violation of this Section 13.1 will be null and void ab initio.

13.2 Public Announcements. Neither Party nor any of their respective Affiliates shall issue any press release or make any public announcement relating to the subject matter of this Agreement without the prior written consent of the other Party, which consent shall not be unreasonably withheld, delayed or conditioned; provided, however, that (a) Buyer may make any public disclosure it believes in good faith, upon advice of counsel, is required by applicable Law or any listing or trading agreement concerning its publicly traded securities (in which case Buyer will provide reasonable advance notice, to the extent reasonably practicable, to Seller prior to making the disclosure and will in good faith consider Seller’s reasonable comments on such disclosure) and (b) either Party may make any public announcement that is substantially consistent with a prior press release or public announcement made with the consent of the other Party.

-58-

13.3 Confidentiality.

(a) Buyer and Seller agree that the Confidentiality Agreement, as it relates to Information, shall, as of the Closing Date, be terminated and of no further force and effect.

(b) Seller agrees that, from the Closing Date until the date that is [***] years following the Closing Date (or, with respect to any Buyer Information delivered to Seller in accordance with Section 3.8, the date that is [***] years following the date of such delivery) or with respect to any Buyer Information that constitutes a trade secret under applicable Law, until the later of the date that is [***] years following the Closing Date and the date on which such Buyer Information no longer constitutes a trade secret under applicable Law (other than as a result of any disclosure in violation of the Confidentiality Agreement, this Agreement or any Ancillary Agreement), Seller, any of its applicable Affiliates, and their Representatives shall (i) shall not use any Buyer Information for any purpose other than as required to perform their respective obligations or exercise or enforce their respective rights and remedies under this Agreement or any Ancillary Agreement or as required to comply with their respective regulatory, stock exchange, Tax, accounting or financial reporting requirements (collectively, “Permitted Uses”), and (ii) subject to Section 13.3(c), (A) not disclose any Buyer Information to any Person other than any of Seller’s Affiliates and Representatives who need to know such Buyer Information for any purpose described in the preceding clause (i) and (B) keep confidential and exercise the same degree of care with respect to maintaining the confidentiality of any Buyer Information in any of their possession that Seller and its Affiliates exercise with respect to similar types of their own proprietary information, but in no event less than a reasonable degree of care. [***].

(c) If any Buyer Information is required by Law or legal or administrative process to be disclosed, Seller shall promptly (and in any event prior to making such disclosure, to the extent permitted by Law) notify Buyer of such disclosure requirement so that Buyer or its Affiliates may seek a protective Order or other appropriate remedy. Seller shall, shall cause its Affiliates to and shall direct its respective Representatives to, reasonably cooperate, at Buyer’s expense, with Buyer or its Affiliates’ efforts to obtain such protective Order or other appropriate remedy. In the event that no such protective Order or other remedy is obtained, or Buyer does not waive compliance with this Section 13.3(c), and any of Seller, its applicable Affiliates, or their Representatives are nonetheless legally compelled to disclose such Buyer Information, then Seller, such Affiliate or such Representative, as the case may be, will furnish only that portion of the Buyer Information which Seller, such Affiliate or such Representative is advised by counsel is legally required to be furnished and will give Buyer written notice of the Buyer Information to be disclosed as far in advance as reasonably practicable and exercise commercially reasonable efforts to obtain reliable assurance that confidential treatment will be accorded the Buyer Information.

Within one (1) Business Day following the date the Registration Statement (as defined in the Registration Rights Agreement) is declared effective, the Company shall provide or cause its legal counsel to provide the transfer agent for the Common Shares (the “Transfer Agent”) one or more opinions regarding the removal of legends in connection with sales or other permitted dispositions pursuant to the effective Registration Statement. In connection therewith, the Company shall use reasonable best efforts to have the Transfer Agent remove any restrictive legends related to the book entry account holding such Shares and make a new, unlegended entry for such book entry Shares sold or disposed of without restrictive legends within two (2) Trading Days receipt of notice of the sale or disposition pursuant to the Registration Statement, provided that the Transfer Agent and/or Company has timely received from the Investor a customary seller representation letter regarding such disposition. In addition, either (i) any time after the holding period specified in Rule 144(d)(1)(ii) has been satisfied or (ii) in connection with any sale, assignment, transfer or other disposition of the Shares by an Investor pursuant to Rule 144 or pursuant to any other exemption under the 1933 Act such that the purchaser acquires freely tradable shares and upon compliance by the Investor with the requirements of this Agreement, if requested by an Investor, the Company shall use reasonable best efforts to have provide or cause its legal counsel to provide the Transfer Agent one or more opinions (including blanket opinions) regarding the removal of legends in reliance of such rule, and to have the Transfer Agent remove any restrictive legends related to the book entry account holding such shares and make a new, unlegended entry for such book entry shares without restrictive legends within two (2) Trading Days of any such request, provided that the Transfer Agent and/or Company has timely received from the Investor customary representations and other documentation reasonably acceptable to the Company in connection therewith.

The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the 1933 Act) that will be integrated with the offer or sale of the Shares in a manner that would require the registration under the 1933 Act of the sale of the Shares to the Investors, or that will be integrated with the offer or sale of the Shares for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction. The Company shall not take any action or steps that would adversely affect reliance by the Company on Section 4(a)(2) and Rule 506(b) of Regulation D for the exemption from registration for the transactions contemplated hereby or require registration of the Shares under the 1933 Act.

7.5 Fees. The Company shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or broker’s commissions (other than for Persons engaged by any Investor) relating to or arising out of the transactions contemplated hereby.

Notwithstanding the foregoing, in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Agreement. Each Investor covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company, such Investor will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction), other than to such Person’s outside attorney, accountant, auditor or investment advisor only to the extent necessary to permit evaluation of the investment, and the performance of the necessary or required tax, accounting, financial, legal, or administrative tasks and services and other than as may be required by law.

To the extent that any notice provided pursuant to any Transaction Document constitutes, or contains, material, nonpublic information regarding the Company or any subsidiaries, the Company shall simultaneously file such notice with the SEC pursuant to a Current Report on Form 8-K.

The Company shall notify the Investors promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by the Transaction Documents of which the Company is aware.

8.3 Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (a) the indemnifying party has agreed in writing to pay such fees or expenses, (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such indemnified party or (c) in the reasonable judgment of any such indemnified party, based upon written advice of its counsel, a conflict of interest exists between such indemnified party and the indemnifying party with respect to such claims (in which case, if the indemnified party notifies the indemnifying party in writing that such indemnified party elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person); and provided, further, that the failure of any indemnified party to give written notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, which consent shall not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation or that includes any admission as to fault, culpability or failure to act on the part of such indemnified party. No indemnified party will, except with the consent of the indemnifying party, which consent shall not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement on any such matter.

The Company hereby acknowledges and agrees that no Investor (nor any of such Investor’s Affiliates, attorneys, accountants, agents or representatives) shall have any duty of trust or confidence (including any such obligation under any confidentiality or non-disclosure agreement entered into by such Investor in connection with the purchase of the Common Shares hereunder) with respect to, or any obligation not to trade in any securities while aware of, any material nonpublic information (X) provided by, or on behalf of, the Company any of its Affiliates or any of their officers, directors (or equivalent persons), employees, attorneys, agents or representatives in violation of any of the representations, warranties, covenants, provisions or agreements set forth in this Section 9.8 or elsewhere herein or (Y) otherwise possessed (or continued to be possessed) by any Investor (or any Affiliate, attorney, accountant, agent or representative thereof) as a result of any breach or violation of any representation, warranty, covenant, provision or agreement set forth in this Section 9.8.

9.9 Severability.

To the extent permitted by applicable law, the parties hereby waive any provision of law which renders any provision hereof prohibited or unenforceable in any respect.

9.10 Entire Agreement. This Agreement, including the signature pages and Exhibits and any confidentiality agreement between the Company and each Investor constitute the entire agreement among the parties hereof with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof.

9.12 Governing Law. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof (other than sections 5-1401 and 5-1402 of the General Obligations Law) to the extent that those principles would result in the application of the laws of another jurisdiction. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court.

EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

9.13 Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase Shares pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Shares or enforcing its rights under the Transaction Documents. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and an Investor, solely, and not between the Company and the Investors collectively and not between and among the Investors.

9.14 Exculpation of the Placement Agents. Each party hereto agrees, for the express benefit of the Placement Agents, their respective affiliates and their respective representatives, that, in connection with the Transaction Documents and the transactions contemplated thereby:

(i) By no later than forty-five (45) calendar days after the Closing Date (the “Filing Deadline”), the Company shall prepare and file with the SEC one (1) Registration Statement covering the resale of all of the Registrable Securities. Subject to any SEC comments, such Registration Statement shall include the plan of distribution substantially in the form attached hereto as Exhibit A; provided, however, that no Investor shall be named as an “underwriter” in such Registration Statement without the Investor’s prior written consent. Such Registration Statement also shall cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional Common Shares resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. Such Registration Statement

2

shall not include any Common Shares or other securities for the account of any other holder. The Company shall not file any other registration statements until the Registration Statement is declared effective by the SEC, provided that this Section 2(a)(i) shall not prohibit the Company from filing (x) amendments to registration statements filed prior to the date of this Agreement, (y) a shelf registration statement on Form S-3 for a primary offering by the Company, provided that the Company makes no offering of securities pursuant to such shelf registration statement prior to the effective date of the Registration Statement required hereunder, or (z) one (1) or more registration statements on Form S-8 for the registration of the securities underlying its equity incentive plans.

(ii) The Registration Statement referred to in Section 2(a)(i) shall be on Form S-3. In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on such other form as is available to the Company and (ii) so long as Registrable Securities remain outstanding, promptly following the date (the “Qualification Date”) upon which the Company becomes eligible to use a registration statement on Form S-3 to register the Registrable Securities for resale, but in no event more than thirty (30) days after the Qualification Date (the “Qualification Deadline”), file a registration statement on Form S-3 covering the Registrable Securities (or a post-effective amendment on Form S-3 to a registration statement on Form S-1) (a “Shelf Registration Statement”) and use commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective as promptly as practicable thereafter; provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Shelf Registration Statement covering the Registrable Securities has been declared effective by the SEC.

(b) Expenses. The Company will pay all expenses associated with each Registration Statement, including filing and printing fees, fees of the Company’s counsel, fees of the Transfer Agent, accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities laws and listing fees, but excluding discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold.

(c) Effectiveness.

(i) The Company shall use commercially reasonable efforts to have each Registration Statement declared effective as soon as practicable after such Registration Statement has been filed with the SEC, but no later than the Effectiveness Deadline. The Company shall notify the Investors by e-mail as promptly as practicable, and in any event within twenty-four (24) hours, after any Registration Statement is declared effective and shall simultaneously provide the Investors with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby.

(ii) On not more than two (2) occasions and for not more than thirty (30) consecutive days or for a total of not more than sixty (60) days, in each case in any twelve (12) month period, the Company may suspend the use of any Prospectus included in any Registration Statement contemplated by this Section 2: (A) if the negotiation or consummation of a transaction by the Company is pending or an event has occurred, which negotiation, consummation or event, the Board of Directors of the Company reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Board of Directors of the Company upon advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements or (B) in the event the Company determines in good faith, upon advice of legal counsel, that suspension is necessary to amend or supplement the affected Registration Statement or the related Prospectus so that such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that the Company shall promptly (a) notify each Investor in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor any material nonpublic information giving rise to an Allowed Delay, (b) advise the Investors in writing to cease all sales under such Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.

(d) Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement.

(i) Subject to Section 2(e), if a Registration Statement covering the Registrable Securities is not filed with the SEC on or prior to the Filing Deadline, the Company will make pro rata payments to each Investor then holding Registrable Securities, as liquidated damages and not as a penalty (the “Registration Liquidated Damages”), in an amount equal to one percent (1.0%) of the aggregate amount invested by such Investor for the initial day of failure to file such Registration Statement by the Filing Deadline and for each thirty (30) day period (or pro rata portion thereof with respect to a final period, if any) thereafter during which no such Registration Statement is filed with respect to the Registrable Securities. Such payments shall be made to each Investor then holding Registrable Securities in cash no later than ten (10) Business Days after the end of the date of the initial failure to file such Registration Statement by the Filing Deadline and each subsequent thirty (30) day period (or portion thereof with respect to a final period, if any) thereafter until such Registration Statement is filed with respect to the Registrable Securities. Interest shall accrue at the rate of one percent (1.0%) per month on any such liquidated damages payments that shall not be paid by the applicable payment date until such amount is paid in full.

(ii) Subject to Section 2(e), if (A) a Registration Statement covering the Registrable Securities is not declared effective by the SEC prior to the earlier of (x) five (5) Business Days after the SEC informs the Company that no review of such Registration Statement will be made or that the SEC has no further comments on such Registration Statement or (y) the Effectiveness Deadline or (B) after a Registration Statement has been declared effective by the SEC, (1) such Registration Statement ceases for any reason (including, without limitation, by reason of a stop order, or the Company’s failure to update the Registration Statement) to remain continuously effective as to sell all Registrable Securities for which it is required to be effective, (2) the Investors are not permitted to utilize the Prospectus therein to resell such Registrable Securities (other than during an Allowed Delay), or (3) an Allowed Delay exceeds the permitted length of the Allowed Delay hereunder, (C) after the Filing Deadline, and only in the event a Registration Statement is not effective or available to sell all Registrable Securities, the Company fails to file with the SEC any required reports under Section 13 or 15(d) of the Exchange Act such that it is not in compliance with Rule 144(c)(1), as result of which holders who are not affiliates are unable to sell Registrable Securities without restriction under Rule 144 or (D) the Registration Statement is on Form S-1, for a period of twenty (20) days following the date on which the Company files a post-effective amendment to incorporate the Company’s Annual Report on Form 10-K (each of (A), (B), (C) and (D), a “Maintenance Failure”), then in addition to any other rights the Investors may have hereunder or under applicable law, then the Company will make pro rata payments to each Investor then holding Registrable Securities, as liquidated damages and not as a penalty (the “Maintenance Liquidated Damages,” and together with the Registration Liquidated Damages, the “Liquidated Damages”), in an amount equal to one percent (1.0%) of the aggregate amount invested by such Investor for the Registrable Securities then held by such Investor for the initial day of a Maintenance Failure and for each thirty (30) day period (or pro rata portion thereof with respect to a final period, if any) thereafter until the Maintenance Failure is cured. The Maintenance Liquidated Damages shall be paid monthly within ten (10) Business Days of the date of such Maintenance Failure and the end of each subsequent thirty (30) day period (or portion thereof with respect to a final period, if any) thereafter until the Maintenance Failure is cured. Such payments shall be made in cash to each Investor then holding Registrable Securities. Interest shall accrue at the rate of one percent (1%) per month on any such liquidated damages payments that shall not be paid by the applicable payment date until such amount is paid in full.

(iii) The parties agree that (1) notwithstanding anything to the contrary herein or in the Purchase Agreement, no Liquidated Damages shall be payable with respect to any period after the expiration of the Effectiveness Period (as defined below) (it being understood that this sentence shall not relieve the Company of any Liquidated Damages accruing prior to the expiration of the Effectiveness Period), and in no event shall the aggregate amount of Liquidated Damages payable to an Investor exceed, in the aggregate, five percent (5.0%) of the aggregate purchase price paid by such Investor pursuant to the Purchase Agreement and (2) in no event shall the Company be liable in any thirty (30) day period for Liquidated Damages under this Agreement in excess of one percent (1.0%) of the aggregate purchase price paid by the Investors pursuant to the Purchase Agreement.

(iv) Notwithstanding the foregoing, the Company and the Investors agree that the Company will not be liable for any liquidated damages under this Section 2(d) with respect to any Registrable Securities prior to their issuance. The Liquidated Damages described in this Section 2(d) shall constitute the Investors’ exclusive monetary remedy for any failure to meet the Filing Deadline and for any Maintenance Failure (unless any of the foregoing shall occur as a result of a willful breach by the Company of its obligations hereunder, in which case, the Investors’ monetary remedies shall not be limited to the Liquidated Damages described herein), but shall not affect the right of the Investors to seek injunctive relief or specific performance of the Company’s obligations hereunder. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Investors by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for breach of its obligations hereunder may be inadequate and agrees, in the event of a breach or threatened breach by the Company of any of the provisions hereunder, that the Investors shall be entitled, in addition to all other available remedies in law or in equity, to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, without the necessity of showing economic loss and without any bond or other security being required.

4

(v) For purposes of clarification, any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve the Company of its obligations to file or effect the Registration Statement as set forth above in this Section 2 and in Section 3.

(e) Rule 415; Cut Back. If at any time the SEC takes the position that the offering of some or all of the Registrable Securities in a Registration Statement is a primary offering or not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the 1933 Act, or requires any Investor to be named as an “underwriter,” the Company shall use commercially reasonable efforts to advocate before the SEC its reasonable position that the offering contemplated by such Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 (a “Constructive Primary Offering”) and that none of the Investors is an “underwriter.” The Investors shall have the right to review and oversee any registration or matters pursuant to this Section 2(e), including participation in any meetings or discussions with the SEC regarding the SEC’s position and to comment on any written submission made to the SEC with respect thereto. In the event that, despite the Company’s commercially reasonable efforts, the SEC does not alter its position, the Company shall (i) remove from such Registration Statement such portion of the Registrable Securities (the “Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Investor as an “underwriter” in such Registration Statement without the prior written consent of such Investor. Any cut back imposed on the Investors pursuant to this Section 2(e) shall be allocated among the Investors on a pro rata basis and shall be applied first to any of the Registrable Securities of such Investor as such Investor shall designate, unless the SEC Restrictions otherwise require or provide or the Investors otherwise agree. The parties agree that the Company’s delay or failure to have a Registration Statement declared effective due to the SEC taking the position that the offering is a Constructive Primary Offering shall not be a breach of any provision of this Agreement and no liquidated damages shall accrue as to any Cut Back Shares. From and after such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions applicable to such Cut Back Shares (such date, the “Restriction Termination Date”), all of the provisions of this Section 2 (including the Company’s obligations with respect to the filing of a Registration Statement and its obligations to use commercially reasonable efforts to have such Registration Statement declared effective within the time periods set forth herein and the liquidated damages provisions relating thereto) shall again be applicable to such Cut Back Shares; provided, however, (i) that the Filing Deadline and/or the Qualification Deadline, as applicable, for such Registration Statement including such Cut Back Shares shall be ten (10) Business Days after such Restriction Termination Date, and (ii) the date by which the Company is required to obtain effectiveness with respect to such Cut Back Shares under Section 2(c) shall be the sixtieth (60th) calendar day immediately after the Restriction Termination Date (or the ninetieth (90th) calendar day if the SEC reviews such Registration Statement); provided, further, that if such date falls on a Saturday, Sunday or other day that the SEC is closed for business, such date shall be extended to the next business day on which the SEC is open for business.

3. Company Obligations. The Company will use commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will, as expeditiously as possible:

(a) use commercially reasonable efforts to cause such Registration Statement to become effective and to remain continuously effective for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement, as amended from time to time, have been sold pursuant to a Registration Statement or Rule 144, and (ii) the date on which all Shares cease to be Registrable Securities (the “Effectiveness Period”);

(b) prepare and file with the SEC such amendments and post-effective amendments to such Registration Statement and the related Prospectus as may be necessary to keep such Registration Statement effective for the Effectiveness Period and to comply with the provisions of the 1933 Act and the 1934 Act with respect to the distribution of all of the Registrable Securities covered thereby;

5

(c) provide copies to and permit each Investor to review each Registration Statement and all amendments and supplements thereto at least two (2) Business Days prior to their filing with the SEC and a reasonable opportunity to furnish comments thereon;

(d) furnish to each Investor whose Registrable Securities are included in any Registration Statement (i) promptly after the same is prepared and filed with the SEC, if requested by the Investor, one (1) copy of any Registration Statement and any amendment thereto, each preliminary prospectus and Prospectus and each amendment or supplement thereto, and each letter written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion thereof which contains information for which the Company has sought confidential treatment), and (ii) such number of copies of a Prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as each Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor that are covered by such Registration Statement;

(e) use commercially reasonable efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order at the earliest practical moment;

(f) use commercially reasonable efforts to cause all Registrable Securities covered by a Registration Statement to be listed on each securities exchange, interdealer quotation system or other market on which similar securities issued by the Company are then listed;

(g) promptly notify the Investors, at any time prior to the end of the Effectiveness Period, upon discovery that, or upon the happening of any event as a result of which, the Prospectus includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing (provided that such notice shall not, without the prior written consent of an Investor, disclose to such Investor any material nonpublic information regarding the Company), and promptly prepare, file with the SEC and furnish to such holder a supplement to or an amendment of such Prospectus as may be necessary so that such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

(h) otherwise use commercially reasonable efforts to (i) comply with all applicable rules and regulations of the SEC under the 1933 Act and the 1934 Act, including, without limitation, Rule 172 under the 1933 Act; (ii) file any final Prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under the 1933 Act; (iii) promptly inform the Investors in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 under the 1933 Act and, as a result thereof, the Investors are required to deliver a Prospectus in connection with any disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder; and (iv) make available to its security holders, as soon as reasonably practicable, an earnings statement satisfying the provisions of Section 11(a) of the 1933 Act;

(i) if requested by an Investor, the Company shall (i) as soon as practicable, incorporate in a prospectus supplement or post-effective amendment such information as an Investor reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable, make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as soon as practicable, supplement or make amendments to any Registration Statement if reasonably requested by an Investor holding any Registrable Securities;

(j) within two (2) Business Days after a Registration Statement which covers Registrable Securities is ordered effective by the SEC, the Company shall deliver to the Transfer Agent (with copies to the Investors whose Registrable Securities are included in such Registration Statement) confirmation that such Registration Statement has been declared effective by the SEC;

6

(k) make available upon reasonable prior notice during normal business hours and for reasonable periods for inspection by the Investors and by any attorney, accountant or other agent retained by the Investors and who is reasonably acceptable to the Company (collectively, the “Inspectors”), all pertinent financial and other records and pertinent corporate documents and properties of the Company (collectively, the “Records”) as may be reasonably necessary for the purpose of such review, and cause the Company’s officers, directors and employees and the independent public accountants who have certified its financial statements to make themselves available to discuss the business of the Company and to supply all information reasonably requested by the Inspectors for the sole purpose of conducting initial and ongoing due diligence with respect to the Company and the accuracy of the Registration Statement; provided, however, that each Investor shall agree to, and to direct its Inspectors to, hold in strict confidence and shall not make any disclosure or use of any Record or other information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (a) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is otherwise required under the 1933 Act, (b) the release of such Records is ordered pursuant to a final, non-appealable subpoena or order from a court or government body of competent jurisdiction, or (c) the information in such Records has been made generally available to the public other than by disclosure in violation of this Section 3(k). Notwithstanding the foregoing, the Company shall not disclose material nonpublic information to the Investors, or to advisors to or representatives of the Investors, unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Investors, such advisors and such representatives with the opportunity to accept or refuse to accept such material nonpublic information for review and any Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto; and

(l) with a view to making available to the Investors the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock to the public without registration: (i) make and keep adequate current public information available, as those terms are understood and defined in Rule 144, until the earlier of (A) six (6) months after such date as all of the Registrable Securities may be sold without restriction by the holders thereof pursuant to Rule 144 or any other rule of similar effect (without restriction, limitation or current information requirement) or (B) such date as all of the Registrable Securities shall have been resold; (ii) file with the SEC in a timely (without giving effect to any extensions that may be available pursuant to Rule 12b-25 under the 1934 Act or any similar provision) manner all reports and other documents required of the Company under the 1934 Act; and (iii) furnish to each Investor upon request, as long as such Investor owns any Registrable Securities, (A) a written statement by the Company that it has complied with the reporting requirements of the 1934 Act, and (B) such other information as may be reasonably requested in order to avail such Investor of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without registration.

4. Obligations of the Investors.

(a) Notwithstanding any other provision of the Agreement, no Investor may include any of its Registrable Securities in the Registration Statement pursuant to this Agreement unless such Investor furnishes to the Company a completed questionnaire substantially in the form of Exhibit B or such other form as agreed upon between the Company and the Investor (the “Questionnaire”) for use in connection with the Registration Statement at or prior to Closing if such Investor elects to have any of the Registrable Securities included in such Registration Statement. In addition to the Questionnaire, each Investor shall furnish such other information as shall be reasonably required to effect the registration of such Registrable Securities, and shall execute such documents in connection with such registration as the Company may reasonably request.

(b) Each Investor, by its acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Investor has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement.

7

(c) Each Investor agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(g) hereof, such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement covering such Registrable Securities, until the Investor is advised by the Company that such dispositions may again be made and/or the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed.

(d) Each Investor covenants and agrees that it will comply with the prospectus delivery requirements of the 1933 Act as applicable to it or an exemption therefrom in connection with sales of Registrable Securities pursuant to any Registration Statement.

(e) Each Investor resident in Canada or otherwise subject to Canadian Securities Laws acknowledges that no prospectus will be filed with Canadian Securities Commissions in order to qualify the distribution of Shares in any province or territory of Canada, and applicable resale restrictions under Canadian Securities Laws will continue to apply to any sale of Shares by such Investor.

5. Indemnification.

(a) Indemnification by the Company. The Company will, notwithstanding any termination of this Agreement, indemnify and hold harmless each Investor and its officers, directors, members, investment advisors, employees and agents, and each other person, if any, who controls such Investor within the meaning of the 1933 Act, against any losses, claims, damages, expenses (including reasonable and documented attorneys’ fees) or liabilities (collectively, “Losses”), joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such Losses (or actions in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof or (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements in any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof, in light of the circumstances under which they were made not misleading, except to the extent that any such Losses arise out of or are based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with any information relating to such Investor furnished in writing by such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto (“Investor Information”), (ii) the use by an Investor of an outdated or defective Prospectus after the Company has notified such Investor in writing that such Prospectus is outdated or defective; or (iii) an Investor’s failure to send or give a copy of the Prospectus or supplement (as then amended or supplemented), if required (and not exempted) to the Persons asserting an untrue statement or omission or alleged untrue statement or omission at or prior to the written confirmation of the sale of Registrable Securities.

(b) Indemnification by the Investors. Each Investor agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law and notwithstanding any termination of this Agreement, the Company, its directors, officers who sign the Registration Statement, employees and each other person who controls the Company (within the meaning of the 1933 Act) against any Losses resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in any Registration Statement or Prospectus or preliminary Prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in the Investor Information. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Investor in connection with any claim relating to this Section 5 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in such Registration Statement giving rise to such indemnification obligation.

(a) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed in writing to pay

8

such fees or expenses, (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give written notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation or that includes any admission as to fault, culpability or failure to act on the part of such indemnified party.

(b) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of an Investor be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 5 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

6. Miscellaneous.

(a) Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the Required Investors.

An Investor or its respective successor or assign may transfer or assign, in whole or from time to time in part, to one or more persons its rights hereunder in connection with the transfer of Registrable Securities by such holder to such person, provided that the transferring holder complies with all laws applicable thereto, and the provisions of the Purchase Agreement, and provides written notice of assignment to the Company promptly after such assignment is effected, with all information reasonably requested by the Company, and such person agrees in writing with the Company to be bound by all of the provisions contained herein and all applicable federal and state laws; provided further, that unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such holder, the amount of Registrable Securities transferred or assigned to such transferee or assignee represents at least $5.0 million of Registrable Securities (based on the then-current market price of the Common Shares).

(d) Assignments and Transfers by the Company. This Agreement may not be assigned by the Company (whether by operation of law or otherwise) without the prior written consent of the Required Investors; provided, however, that in the event that the Company is a party to a merger, consolidation, share exchange or similar business combination transaction in which the Common Shares are converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Registrable Securities” shall be deemed to include the securities received by the Investors in connection with such transaction unless such securities are otherwise freely tradable by the Investors after giving effect to such transaction.

9

(e) Benefits of the Agreement. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties.

(f) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signatures complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

To the extent permitted by applicable law, the parties hereby waive any provision of law which renders any provisions hereof prohibited or unenforceable in any respect.

(i) Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

Plan of Distribution

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling common shares or interests in common shares received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their common shares or interests in common shares on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the common shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the common shares, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended (the “Securities Act”), amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the common shares in other circumstances, in which case the transferees, pledgees, donees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of our common shares or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common shares in the course of hedging the positions they assume. The selling stockholders may also sell our common shares short and deliver these securities to close out their short positions, or loan or pledge the common shares to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the common shares offered by them will be the purchase price of the common shares less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common shares to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common shares or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, our common shares to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934, as amended, may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling stockholders to use commercially reasonable efforts to cause the registration statement of which this prospectus constitutes a part effective and to remain continuously effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with such registration statement or (2) the date on which all of the shares may be sold without restriction pursuant to Rule 144 of the Securities Act.

Exhibit 99.1

Fusion Pharmaceuticals to Acquire Phase 2 Program for

²²⁵Ac-PSMA I&T, a Radiopharmaceutical Targeting Metastatic Castrate Resistant Prostate Cancer

Acquisition of Phase 2 program with established clinical proof of concept strengthens pipeline of innovative targeted alpha therapies

In connection with the transaction, Fusion announces $60.0 million private placement financing

Fusion to host conference call at 4:45 ET

Hamilton, ON & Boston, MA, February 13, 2023 – Fusion Pharmaceuticals Inc. (Nasdaq: FUSN) (“Fusion”), a clinical-stage oncology company focused on developing next-generation targeted alpha therapies (“TATs”) as precision medicines, today announced the acquisition from RadioMedix, Inc. (“RadioMedix”) of the investigational new drug application (“IND”) for an ongoing Phase 2 clinical trial (the “TATCIST” trial) evaluating ²²⁵Ac-PSMA I&T, a small molecule targeting prostate specific membrane antigen (“PSMA”) expressed on prostate cancers. Following the closing, the alpha-emitting radiopharmaceutical being evaluated in the TATCIST trial will be known as FPI-2265.

“We are pleased to announce this acquisition, which adds an ongoing Phase 2 program for a validated cancer target to our pipeline of innovative TATs,” commented Fusion Chief Executive Officer John Valliant, Ph.D. “From our inception, Fusion has recognized the potential opportunity for actinium-based therapies to address unmet needs in cancer given the power and potency of alpha radiation. We believe that with Fusion’s TAT development expertise, and early investments that provide us with our actinium supply advantage, we are uniquely positioned to be first-to-market with an actinium-based PSMA agent.”

“A growing body of clinical data demonstrates the power of targeted alpha therapies in prostate cancer, including for patients who progress on or after lutetium-based PSMA therapies,” said Oliver Sartor, M.D, Laborde Professor for Cancer Research and Medical Director at Tulane Cancer Center. “With more than 250 patients treated with actinium-based radiopharmaceuticals targeting PSMA in investigator sponsored studies, this class of therapy has both the efficacy data and safety profile that supports continued development. I believe ²²⁵Ac-PSMA I&T will have the potential to target a growing patient population with significant unmet need. In addition, it has the potential to move into earlier lines of therapy as monotherapy as well as in combination with other agents.”

The TATCIST trial is designed to evaluate patients with metastatic castration-resistant prostate cancer (“mCRPC”) with progressive disease, including patients who are naïve to PSMA targeted radiopharmaceuticals and those who have been pre-treated with ¹⁷⁷Lu-based PSMA radiopharmaceuticals such as PLUVICTO^™. The trial is expected to evaluate approximately 100 patients with four treatment cycles per patient occurring every eight weeks. Patients are initially dosed at 100 kBq/kg with dose de-escalation possible based on biochemical response. Efficacy will be assessed using change in PSA levels and radiographic response.

Fusion plans to expand the Phase 2 program to additional sites and expects to report data on 20 to 30 patients in the first quarter of 2024.

“Having treated mCRPC patients for many years, I initiated the TATCIST trial to address the unmet needs for the many patients who are not adequately addressed with currently available therapies,” said Ebrahim Delpassand, M.D., Chairman and CEO of RadioMedix and Medical Director of Excel Diagnostics & Nuclear Oncology Center. “Given Fusion’s radiopharmaceutical development capabilities, leadership in Actinium supply and established infrastructure, we look forward to this preeminent partnership to advance FPI-2265 through the Phase 2 program for the benefit of our patients.”

Dr. Valliant continued, “With one Phase 2 program, three ongoing Phase 1 programs, and an IND submission through our collaboration with AstraZeneca expected in the first quarter of 2023, Fusion continues to extend its leadership in targeted alpha therapy development. Following the encouraging data we reported from the cold antibody sub study of the FPI-1434 trial in June, we continue to dose escalate and we look forward to reporting the preliminary Phase 1 data in the second quarter of this year. The FPI-1434 data will be the first in what we expect will be multiple clinical updates generated from our pipeline over the next 24 months.”    

Private Placement Financing

In connection with the closing of the acquisition of the TATCIST trial and related assets, Fusion has agreed to sell an aggregate of [•] common shares to certain accredited institutional investors in a private placement in public equity financing (the “Offering”). The Offering is expected to result in gross proceeds to Fusion of approximately $[•] million, before deducting placement agent fees and other offering expenses payable by Fusion.

Pursuant to the terms of the securities purchase agreement, at the closing of the Offering, Fusion will issue approximately 17.6 million of its common shares at a price of $3.40 per share, equal to the closing price of Fusion’s common shares, as reported by Nasdaq on February 10, 2023. The closing of the Offering is subject to customary closing conditions and is expected to occur on or about February 16, 2023.

Morgan Stanley and Jefferies served as co-placement agents for the Offering. New and existing investors in the Offering include Avidity Partners, Federated Hermes Kaufmann Funds, a fund affiliated with Deerfield Management Company, L.P., Invus, Perceptive Advisors and Woodline Master Fund LP.

Upon the closing of the Offering, Fusion anticipates having $248.0 million in cash and cash equivalents, which it believes will be sufficient to fund its planned operating expenses and capital expenditure requirements into the first quarter of 2025.

The offer and sale of the foregoing shares are being made in a transaction not involving a public offering and have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). The shares being issued in the private placement may not be offered or sold in the United States or Canada absent registration or pursuant to an exemption from the registration requirements of the Securities Act and applicable state securities laws or pursuant to an exemption from the prospectus requirements of Canadian securities laws, as applicable. Fusion has agreed to file a registration statement with the Securities and Exchange Commission covering the resale of the shares acquired by the investors in the private placement.

This press release does not constitute an offer to sell or the solicitation of an offer to buy the securities, nor shall there be any sale of the securities in any state in which such offer or sale would be unlawful prior to the registration or qualification under the securities laws of such state. Any offering of the shares under the resale registration statement will only be by means of a prospectus.

Exhibit 99.3

As used in this Exhibit 99.3, unless the context indicates otherwise, references to “Fusion,” “the Company,” “we,” “us,” “our” and similar references refer to Fusion Pharmaceuticals, Inc. and its wholly owned subsidiaries.

Risks associated with the in-licensing or acquisition of drug candidates could cause substantial delays in the preclinical and clinical development of our drug candidates.

We acquired rights to FPI-2265, our newly acquired PSMA-I&T asset from RadioMedix Inc., or RadioMedix, in February, 2023, after exercising our rights under an option and asset purchase agreement entered into in November 2022. Because we were not involved in the preclinical or clinical development of FPI-2265 prior to such date, we may experience difficulties in the transition of certain development activities from RadioMedix and its affiliates to us, which may result in delays in clinical trials, as well as problems in our development efforts, particularly if we do not receive all of the necessary information, reports and data from RadioMedix and its affiliates in a timely manner. Further, we have had no involvement with or control over the preclinical and clinical development of FPI-2265 to date. We have relied on RadioMedix having conducted such research and development in accordance with the applicable protocol, legal, regulatory and scientific standards, having accurately reported the results of all clinical trials conducted prior to our agreement with RadioMedix and having correctly collected and interpreted the data from these trials. To the extent any of these has not occurred, expected development time and costs may be increased which could adversely affect any future revenue from this drug candidate.

We may also acquire or in-license additional drug candidates for preclinical or clinical development in the future as we continue to build our pipeline. The risks associated with acquiring or in-licensing current or future drug candidates could result in delays in the commencement or completion of our preclinical studies and clinical trials, if ever, and our ability to generate revenues from our drug candidates may be delayed.

Third-party claims of intellectual property infringement may prevent or delay our product discovery and development efforts.

Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a substantial amount of litigation involving the infringement of patents and other intellectual property rights in the biotechnology and pharmaceutical industries. We may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights and who allege that our product candidates, uses and/or other proprietary technologies infringe their intellectual property rights. We are aware of certain third party patent rights that some may argue cover our FPI-2265, our PSMA I&T product candidate or its use. We have filed an Inter Partes Review (IPR) petition with the United States Patent and Trademark Office to challenge the validity of a certain issued U.S. Patent. In the event that we are unsuccessful in the IPR and that such patent has not expired at the time of approval of FPI-2265, our PSMA I&T product candidate and the patent owners were to bring an infringement action against us, we may have to argue that FPI-2265, our PSMA I&T product candidate, its manufacture or use does not infringe a valid claim of the patent in question. Furthermore, if we were to challenge the validity of this or any other issued U.S. patent in court, we would need to overcome a statutory presumption of validity that attaches to every U.S. patent. This means that in order to prevail, we would need to present clear and convincing evidence as to the invalidity of the patent’s claims. There is no assurance that a court would find in our favor on questions of infringement or validity. In the event that a patent is successfully asserted against us such that the patent is found to be valid and enforceable and infringed by FPI-2265, our PSMA I&T product candidate or its use, unless we obtain a license to such a patent, which may not be available on commercially reasonable terms or at all, we could be prevented from continuing to develop or commercialize our product.

Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing our product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk that our product candidates may give rise to claims of infringement of the patent rights of others increases. Moreover, it is not always clear to industry participants, including us, which patents exist which may be found to cover various types of drugs, products or their methods of use or manufacture. Thus, because of the large number of patents issued and patent applications currently pending in our fields, there may be a risk that third parties may allege they have patent rights which are infringed by our product candidates, technologies or methods.

If a third party alleges that we infringe its intellectual property rights, we may face a number of issues, including, but not limited to:

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations or could otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

Third parties may assert that we are employing their proprietary technology without authorization. Generally, conducting preclinical and clinical trials and other development activities in the United States is not considered an act of infringement. If FPI-1434, FPI-1966, FPI-2059 or another product candidate is approved by the FDA, a third party may then seek to enforce its patent by filing a patent infringement lawsuit against us. While we may believe that patent claims or other intellectual property rights of a third party would not have a materially adverse effect on the commercialization of our product candidates, we may be incorrect in this belief, or we may not be able to prove it in litigation. In this regard, patents issued in the United States by law enjoy a presumption of validity that can be rebutted only with evidence that is “clear and convincing,” a heightened standard of proof. There may be issued third-party patents of which we are currently unaware with claims to compositions, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Patent applications can take many years to issue. There may be currently pending patent applications which may later result in issued patents that may be infringed by our product candidates. Moreover, we may fail to identify relevant patents or incorrectly conclude that a patent is invalid, not enforceable, exhausted, or not infringed by our activities. If any third-party patents, held now or obtained in the future by a third party, were found by a court of competent jurisdiction to cover the manufacturing process of our product candidates, constructs or molecules used in or formed during the manufacturing process, or any final product or methods use of the product, the holders of any such patents may be able to block our ability to commercialize the product candidate unless we obtained a license under the applicable patents, or until such patents expire or they are finally determined to be held invalid or unenforceable. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover any aspect of our formulations, any combination therapies or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize the product candidate unless we obtained a license or until such patent expires or is finally determined to be held invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, or at all, our ability to commercialize our product candidates may be impaired or delayed, which could in turn significantly harm our business. Even if we obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

Parties making claims against us may seek and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our product candidates. Defense of these claims, regardless of their merit, could involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need or may choose to obtain licenses from third parties to advance our research or allow commercialization of our product candidates. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize our product candidates, which could harm our business significantly.

Our proprietary position depends upon patents that are manufacturing, formulation or method-of-use patents, which may not prevent a competitor or other third party from using the same product candidate for another use.

Composition-of-matter patents on the active pharmaceutical ingredient, or API, in prescription drug products are generally considered to be the strongest form of intellectual property protection for drug products because such patents provide protection without regard to any particular method of use or manufacture or formulation of the API used. We currently have claims in an in-licensed issued U.S. patent that cover the antibody composition of matter incorporated in some of our product candidates. We license at least one issued U.S. patent with claims that cover the FPI-1434 product candidate. We are pursuing claims in our owned and in-licensed pending patent applications to provide additional compositions of matter coverage, including coverage of our product candidates. We cannot be certain that claims in any future patents issuing from our pending owned or in-licensed patent applications or our future owned or in-licensed patent applications will cover the composition of matter of our current or future product candidates.

However, we do not own or in-license any composition of matter patents or patent applications in the United States or any other jurisdiction with respect to our FPI-2265 product candidate. Further, we do not currently own or in-license any U.S. or foreign patents or patent applications covering our FPI-2265 product candidate, including method of use patents or patent applications or formulation patents or patent applications. Although we intend to file patent applications in the future that cover our FPI-2265 product candidate, we cannot be certain that our future owned or licensed patent applications will cover our FPI-2265 product candidate. As a result, our owned patent portfolio and any patent portfolio we may license in the future may not provide us with adequate and continuing patent protection sufficient to exclude others from commercializing products similar or identical to our FPI-2265 product candidate.

Method-of-use patents protect the use of a product for the specified method and formulation patents cover formulations of the API. These types of patents do not prevent a competitor or other third party from developing or marketing an identical product for an indication that is outside the scope of the patented method or from developing a different formulation that is outside the scope of the patented formulation. Moreover, with respect to method-of-use patents, even if competitors or other third parties do not actively promote their product for our targeted indications or uses for which we may obtain patents, physicians may recommend that patients use these products off-label, or patients may do so themselves. Although off-label use may infringe or contribute to the infringement of method-of-use patents, the practice is common, and this type of infringement is difficult to prevent or prosecute. In addition, there are numerous publications and other prior art that may be relevant to our owned or in-licensed method-of-use patents and patent applications and may be used to challenge the validity of these owned or in-licensed patents and patent applications in litigation or other intellectual property-related proceedings. If these types of challenges are successful, our owned or in-licensed patents and patent applications may be narrowed or found to be invalid and we may lose valuable intellectual property rights. Any of the foregoing could have a material adverse effect on our business, financial conditions, prospects and results of operations.
