Subject to the foregoing, if a Product is sold or otherwise commercially disposed of for consideration other than cash or in a transaction that is not at arm’s-length between the buyer and the seller, then the gross amount to be included in the calculation of Product Sales shall be the amount that would have been invoiced had the transaction been conducted at arm’s-length and for cash.

(ii) In the event that the Company, its Affiliates or licensees of the Company and its Affiliates do not sell during such period the Product included in a Combination Sale as a separate product in the jurisdiction where such Combination Sale occurs, but there are separate sales during such period of all of the other products or active ingredients/components, as the case may be, included in the Combination Sale in such jurisdiction, the calculation of Product Sales resulting from such Combination Sale shall be determined by multiplying the gross amount invoiced for the Combination Product (less all Permitted Deductions) by the fraction (C-D)/C, where C is the average selling price charged by the Company, its Affiliates or licensees of the Company or its Affiliates in such jurisdiction for such Combination Product during such period, and D is the aggregate of the average selling price(s) charged by the Company, its Affiliates or licensees of the Company or its Affiliates, as applicable, in such jurisdiction, of such other product(s) or active ingredients/components, as the case may be, included in the Combination Product and sold separately in such jurisdiction during such period.

If the calculation of Product Sales resulting from a Combination Sale in a jurisdiction cannot be determined by either of the foregoing methods, the calculation of Product Sales for such Combination Sale shall be calculated in a manner determined by the Company in good faith based upon the relative value of the active components of such Combination Product.

“Product Sales Milestone” means each of (a) Product Sales Milestone #1 and (b) Product Sales Milestone #2.

“Product Sales Milestone #1” means the first calendar month prior to the Termination Date in which the aggregate Product Sales during the consecutive twelve (12) month period ending on the last day of such calendar month equals or exceeds a total of forty million dollars ($40,000,000).

Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Security shall bind every future Holder of the same Security or the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, suffered or omitted to be done by the Trustee, any Paying Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this CVR Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(b) In case by reason of the suspension of regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event as required by any provision of this CVR Agreement, then any method of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

(ii) At the option of the Holder, CVR Certificates may be exchanged for other CVR Certificates that represent in the aggregate the same number of CVRs as the CVR Certificates surrendered at such office or agency. Whenever any CVR Certificates are so surrendered for exchange, the Company shall execute and the Trustee shall authenticate and deliver, the CVR Certificates which the Holder making the exchange is entitled to receive.

(iii) The transfer and exchange of beneficial interests in the Global Securities will be effected through the Depositary, in accordance with the provisions of this CVR Agreement and the Applicable Procedures. Beneficial interests in any Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in Global Security. No written orders or instructions shall be required to be delivered to the Security Registrar to effect the transfers described in this SECTION 3.4(b)(iii).

(iv) If any holder of a beneficial interest in a Global Security proposes to exchange such beneficial interest for a Direct Registration Security or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Direct Registration Security, then the Security Registrar will cause the aggregate number of CVRs represented by the applicable Global Security to be reduced accordingly pursuant to SECTION 3.4(b)(vii) hereof, and the Security Registrar will deliver to the Person designated in the instructions a Direct Registration Security in the appropriate number of CVRs. Any Direct Registration Security issued in exchange for a beneficial interest pursuant to this SECTION 3.4(b)(iv) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Security Registrar from or through the Depositary and the Participant or Indirect Participant.

(v) A Holder of a Direct Registration Security may exchange such Direct Registration Security for a beneficial interest in a Global Security or transfer such Direct Registration Security to a Person who takes delivery thereof in the form of a beneficial interest in a Global Security at any time. Upon receipt of a request for such an exchange or transfer, the Security Registrar will cancel the applicable Direct Registration Security and increase or cause to be increased the aggregate number of CVRs represented by one of the Global Securities.

(vi) Upon request by a Holder of Direct Registration Securities and such Holder’s compliance with the provisions of this SECTION 3.4(b)(vi), the Security Registrar will register the transfer or exchange of Direct Registration Securities. Prior to such registration of transfer or exchange, the requesting Holder must present to the Security Registrar a written instruction of transfer in form satisfactory to the Security Registrar duly executed by such Holder or by its attorney, duly authorized in writing. A Holder of Direct Registration Securities may transfer such Direct Registration Securities to a Person who takes delivery thereof in the form of Direct Registration Securities. Upon receipt of a request to register such a transfer, the Security Registrar shall register the Direct Registration Securities pursuant to the instructions from the Holder thereof.

(vii) At such time as all beneficial interests in a particular Global Security have been exchanged for Direct Registration Securities or a particular Global Security has been repurchased or canceled in whole and not in part, each such Global Security will be returned to or retained and canceled by the Security Registrar in accordance with SECTION 3.8 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Direct Registration Securities, the aggregate number of CVRs represented by such Global

Security will be reduced accordingly and an endorsement will be made on such Global Security by the Security Registrar or by the Depositary at the direction of the Security Registrar to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security, such other Global Security will be increased accordingly and an endorsement will be made on such Global Security by the Security Registrar or by the Depositary at the direction of the Security Registrar to reflect such increase.

(viii) (A) To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Securities upon receipt of a Company Order in accordance with SECTION 3.3 hereof or at the Security Registrar’s request.

(B) No service charge will be made to a Holder of a beneficial interest in a Global Security or to a Holder of a Direct Registration Security for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

(C) All Global Securities and Direct Registration Securities issued upon any registration of transfer or exchange of Global Securities or Direct Registration Securities will be the valid obligations of the Company, evidencing the same rights, and entitled to the same benefits under this CVR Agreement, as the Global Securities or Direct Registration Securities surrendered upon such registration of transfer or exchange.

(D) The Trustee will authenticate Global Securities and CVR Certificates in accordance with the provisions of SECTION 3.3 hereof.

SECTION 3.5 Mutilated, Destroyed, Lost and Stolen Securities.

(a) If (i) any mutilated Global Security or CVR Certificate is surrendered to the Trustee, or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Global Security or CVR Certificate, and there is delivered to the Company and the Trustee (A) such security or indemnity as may be reasonably required by them to save each of them and any agent of either harmless and (B) an affidavit of loss in respect of such Security, then, in the absence of notice to the Company or the Trustee that such Global Security or CVR Certificate has been acquired by a bona fide purchaser, the Company shall execute and, upon delivery of a Company Order, the Trustee shall authenticate, as applicable, and deliver, in exchange for any such mutilated Global Security or CVR Certificate or in lieu of any such destroyed, lost or stolen Security, a new CVR, in the form of either a Global Security, a CVR Certificate or a Direct Registration Security, of like tenor and amount of CVRs, bearing a number not contemporaneously outstanding.

(b) In case any such mutilated, destroyed, lost or stolen Global Security or CVR Certificate has become or is to become finally due and payable within fifteen (15) days, the Company in its discretion may, instead of issuing a new CVR, pay to the Holder of such Security on the applicable Payment Date, as the case may be, all amounts due and payable with respect thereto.

(c) Every new Security issued pursuant to this SECTION 3.5 in lieu of any destroyed, lost or stolen Global Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this CVR Agreement equally and proportionately with any and all other Securities duly issued hereunder.

(d) The provisions of this SECTION 3.5 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.6 Payments with Respect to CVRs. Payment of any amounts pursuant to the CVRs shall be made in such coin or currency of the United States of America as at the time is legal tender for the payment of public and private debts. The Company may, at its option, pay such amounts by wire transfer or check payable in such money.

SECTION 3.7 Persons Deemed Owners. Prior to the time of due presentment for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payment on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 3.8 Cancellation. All Securities surrendered for payment, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company shall promptly deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company has acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this SECTION 3.8, except as expressly permitted by this CVR Agreement. All cancelled Securities held by the Trustee shall be destroyed and a certificate of destruction shall be issued by the Trustee to the Company, unless otherwise directed by a Company Order.

SECTION 3.9 CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use). The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document, but the Trustee in its discretion may make such further inquiry or investigation into such facts or matters as it may see fit, and if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, as necessary for such inquiry or investigation at the sole cost of the Company and shall incur no liability of any kind by reason of such inquiry or investigation other than as a result of Trustee’s gross negligence or willful misconduct;

SECTION 4.3 Not Responsible for Recitals or Issuance of Securities. The Trustee shall not be accountable for the Company’s use of the Securities by any Person other than the Trustee. The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this CVR Agreement or of the Securities.

SECTION 4.4 May Hold Securities. The Trustee, any Paying Agent, Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities, and, subject to SECTIONS 4.7 and 4.12, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar or such other agent.

The Company’s payment obligations pursuant to this SECTION 4.6 shall survive the termination of this CVR Agreement. When the Trustee incurs expenses after the occurrence of a Breach specified in SECTION 8.1(c) or 8.1(d) with respect to the Company, the expenses are intended to constitute expenses of administration under bankruptcy Laws.

(c) In the event the Trustee shall fail to comply with the foregoing subsection 4.7(a) after written request therefor by the Company or any Holder, any Holder of any Security who has been a bona fide Holder for at least six (6) months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of such Trustee and the appointment of a successor Trustee.

SECTION 4.8 Corporate Trustee Required; Eligibility. There shall at all times be a Trustee hereunder which satisfies the applicable requirements of Sections 310(a)(1) and (5) of the Trust Indenture Act and has a combined capital and surplus of at least fifty million dollars ($50,000,000). If such corporation publishes reports of condition at least annually, pursuant to Law or to the requirements of a supervising or examining authority, then for the purposes of this SECTION 4.8, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this SECTION 4.8, it shall resign immediately in the manner and with the effect hereinafter specified in this ARTICLE 4.

(b) The Trustee, or any trustee or trustees hereafter appointed, may resign at any time by giving written notice thereof to the Company.

(c) The Trustee may be removed at any time by a demand in writing by the Holders of at least a majority of the Outstanding CVRs delivered to the Trustee and to the Company.

(d) If at any time:

(i) the Trustee shall fail to comply with SECTION 4.7 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six (6) months; or

(ii) the Trustee shall cease to be eligible under SECTION 4.8 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any case, (A) the Company, by a Board Resolution or action of its Chief Executive Officer, may remove the Trustee, or (B) the Holder of any Security who has been a bona fide Holder of a Security for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution and/or action of its Chief Executive Officer, shall promptly appoint a successor Trustee. If, within one (1) year after any removal by the Holders of at least a majority of the Outstanding CVRs, a successor Trustee shall be appointed by act of the Holders of at least a majority of the Outstanding CVRs delivered to the Company and the retiring Trustee the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with SECTION 4.10, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders of the Securities and accepted appointment within sixty (60) days after the retiring Trustee tenders its resignation or is removed, the retiring Trustee may (at the expense of the obligor), or, the Holder of any Security who has been a bona fide Holder for at least six (6) months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. If any Trustee is removed with or without cause, all fees and expenses (including the reasonable fees and expenses of counsel) of such Trustee incurred in the administration of the trust or in performing its duties hereunder shall be paid to such Trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee by mailing written notice of such event by first-class mail, postage prepaid, to the Holders of Securities as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. If the Company fails to send such notice within ten (10) days after acceptance of appointment by a successor Trustee, it shall not be a breach hereunder but the successor Trustee shall cause the notice to be mailed at the expense of the Company.

SECTION 4.10 Acceptance of Appointment of Successor.

(a) Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, upon request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. Notwithstanding the replacement of the Trustee pursuant to this SECTION 4.10, the Company’s obligations under SECTION 4.6 shall continue and inure to the benefit of the retiring Trustee.

In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion, sale or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities; and such certificate shall have the full force which it is anywhere in the Securities or in this CVR Agreement provided that the certificate of the Trustee shall have; provided that the right to adopt the certificate of authentication of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 4.12 Preferential Collection of Claims Against Company. If and when the Trustee shall be or shall become a creditor, directly or indirectly, secured or unsecured, of the Company (or any other obligor upon the Securities), excluding any creditor relationship set forth in Section 311(b) of the Trust Indenture Act, if applicable, the Trustee shall be subject to the applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

Promptly following any amendment of this CVR Agreement or the Securities in accordance with this SECTION 6.1, the Company shall notify the Holders of the Securities of such amendment; provided, that any failure so to notify the Holders shall not affect the validity of such amendment.

SECTION 6.2 Amendments with Consent of Holders. With the consent of the Holders of at least a majority of the Outstanding CVRs, by Act of said Holders delivered to the Company and the Trustee (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Securities), the Company (when authorized by a Board Resolution and/or its Chief Executive Officer) and the Trustee may enter into one or more amendments hereto or to the Securities for the purpose of adding any provisions to

or changing in any manner or eliminating any of the provisions of this CVR Agreement or to the Securities or of modifying in any manner the rights of the Holders under this CVR Agreement or to the Securities; provided, however, that no such amendment shall, without the consent of the Holder of each Outstanding Security affected thereby:

(a) modify in a manner adverse to the Holders (i) any provision contained herein with respect to the termination of this CVR Agreement or the Securities, (ii) the time for payment and amount of any Product Sales Milestone Payment or the Approval Milestone Payment, or otherwise extend the time for payment of the Securities or reduce the amounts payable in respect of the Securities or modify any other payment term or Payment Date;

SECTION 6.3 Execution of Amendments. In executing any amendment permitted by this ARTICLE 6, the Trustee (subject to SECTION 4.1) shall be fully protected in relying upon (i) an Opinion of Counsel and Officer’s Certificate stating that the execution of such amendment is authorized or permitted by this CVR Agreement and (ii) if such amendment is executed pursuant to SECTION 6.2, evidence of the consent of the Holders required to consent thereto. The Trustee shall execute any amendment authorized pursuant to this ARTICLE 6 if the amendment does not adversely affect the Trustee’s own rights, duties or immunities under this CVR Agreement or otherwise. Otherwise, the Trustee may, but need not, execute such amendment.

SECTION 6.4 Effect of Amendments; Notice to Holders.

(a) Upon the execution of any amendment under this ARTICLE 6, this CVR Agreement and the Securities shall be modified in accordance therewith, and such amendment shall form a part of this CVR Agreement and the Securities for all purposes; and every Holder of Securities theretofore or thereafter authenticated, as applicable, and delivered hereunder shall be bound thereby.

(b) Promptly after the execution by the Company and the Trustee of any amendment pursuant to the provisions of this ARTICLE 6, the Company shall mail a notice thereof by first-class mail to the Holders of Securities at their addresses as they shall appear on the Security Register, setting forth in general terms the substance of such amendment. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment.

SECTION 6.5 Conformity with Trust Indenture Act. Every amendment executed pursuant to this ARTICLE 6 shall conform to the applicable requirements of the Trust Indenture Act, if any.

SECTION 6.6 Reference in Securities to Amendments. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. Securities authenticated and delivered after the execution of any amendment pursuant to this ARTICLE 6 may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such amendment. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee on the one hand and the Board of Directors and/or the Chief Executive Officer of the Company on the other hand, to any such amendment may be prepared and executed by the Company, as applicable, and authenticated, as applicable, and delivered by the Trustee in exchange for Outstanding Securities. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

ARTICLE 7

COVENANTS

SECTION 7.1 Payment of Amounts, if any, to Holders. The Company shall duly and punctually pay the amounts, if any, on the Securities in accordance with the terms of the Securities and this CVR Agreement. Such amounts shall be considered paid on the applicable Payment Date if on such date the Trustee or the Paying Agent holds in accordance with this CVR Agreement money sufficient to pay all such amounts then due. Notwithstanding any other provision of this CVR Agreement, the Company or any of its Affiliates (including the Surviving Corporation, as applicable), the Trustee or the Paying Agent, shall be entitled to deduct and withhold, or cause to be deducted and withheld, from any amounts payable or otherwise deliverable pursuant to this CVR Agreement to any Holder such amounts as are required to be deducted and withheld therefrom under the Code or the Treasury Regulations thereunder or any other Tax Law. If Trustee or the Paying Agent intends to withhold any amounts from amounts payable under this CVR Agreement, then Trustee or the Paying Agent shall provide thirty (30) days advance notice of such intended withholding to the payee explaining the basis therefor in order to give the payee an opportunity to provide any information or documentation that may be necessary in order to prevent such withholding.

SECTION 7.2 Maintenance of Office or Agency.

(a) As long as any of the Securities remain Outstanding, the Company shall maintain in the city of New York an office or agency (i) where Securities may be presented or surrendered for payment, (ii) where Securities may be surrendered for registration of transfer or exchange and (iii) where notices and demands to or upon the Company in respect of the Securities and this CVR Agreement may be served. The Corporate Trust Office shall be such office or agency of

the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company or any of its Subsidiaries may act as Paying Agent, registrar or transfer agent; provided that such Person shall take appropriate actions to avoid the commingling of funds. The Company shall give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

(b) The Company may from time to time designate one or more other offices or agencies (in or outside of the city of New York) where the Securities may be presented or surrendered for any or all such purposes, and may from time to time rescind such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the city of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such office or agency.

SECTION 7.3 Money for Security Payments to Be Held in Trust.

(a) If the Company or any of its Subsidiaries shall at any time act as the Paying Agent, it shall, on or before the Payment Date, as the case may be, segregate and hold in trust for the benefit of the Holders all sums held by such Paying Agent for payment on the Securities until such sums shall be paid to the Holders as herein provided, and shall promptly notify the Trustee of any failure of the Company to make payment on the Securities.

(b) Whenever the Company shall have one or more Paying Agents for the Securities, it shall, on or before a Payment Date deposit with a Paying Agent a sum in same day funds sufficient to pay the amount, if any, so becoming due; such sum to be held in trust for the benefit of the Persons entitled to such amount, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of such action or any failure so to act.

(c) The Company shall cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this SECTION 7.3, that (i) such Paying Agent shall hold all sums held by it for the payment of any amount payable on Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall notify the Trustee of the sums so held and (ii) that it shall give the Trustee notice of any failure by the Company (or by any other obligor on the Securities) to make any payment on the Securities when the same shall be due and payable.

(d) Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment on any Security and remaining unclaimed for one (1) year after the Payment Date shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money shall thereupon cease.

SECTION 7.4 Certain Purchases and Sales. The Company or any of its Subsidiaries or Affiliates may acquire in open market transactions, private transactions or otherwise, the Securities, provided that prior to any acquisition of any Securities, the Company must publicly disclose the amount of Securities which it has been authorized to acquire and the Company must report in each of its annual and quarterly reports the amount of Securities it has been authorized to acquire as well as the amount of Securities it has acquired as of the end of the quarterly or annual period reported in such quarterly or annual report.

SECTION 7.5 Books and Records. The Company shall keep, and shall cause its Subsidiaries to keep, true, complete and accurate records in sufficient detail to enable the amounts payable under this CVR Agreement to be determined by the Holders and their consultants or professional advisors, for a period of three (3) years following the Termination Date.

SECTION 7.6 Audits.

(a) Upon the written request of the Acting Holders (but no more than once during any calendar year), and upon reasonable notice, the Company shall provide an independent certified public accounting firm of nationally recognized standing jointly agreed upon by the Acting Holders and the Company (failing agreement on which each shall designate an independent public accounting firm of its own selection, which firms shall in turn appoint an independent public accounting firm for such purpose) (the “Independent Accountant”) with access during normal business hours to such of the records of the Company as may be reasonably necessary to verify the accuracy of the statements set forth in the Product Sales Statements and the figures underlying the calculations set forth therein for any period within the preceding three (3) years that has not previously been audited in accordance with this SECTION 7.6. The fees charged by such accounting firm shall be paid by the Company. The Independent Accountant shall disclose to the Acting Holders any matters directly related to their findings and shall disclose whether it has determined that any statements set forth in the Product Sales Statements are incorrect. The Independent Accountant shall provide the Company with a copy of all disclosures made to the Acting Holders. This covenant shall survive the termination of this CVR Agreement for a period of one (1) year. The initiation of a review by the Acting Holders as contemplated by this SECTION 7.6 shall not relieve the Company of its obligation to pay any Product Sales Milestone Payment relating to any Product Sales Milestone for which notice of achievement has been given in a Product Sales Statement, it being understood that the Company shall also be obligated to pay the full amount of the CVR Shortfall, if any, determined in accordance with SECTION 7.6(b).

(b) If the Independent Accountant concludes that any Product Sales Milestone Payment should have been paid but was not paid when due, the Company shall pay each Holder of a CVR the amount of such Product Sales Milestone Payment (to the extent not paid on a subsequent date), as applicable, plus interest on such Product Sales Milestone Payment, as applicable, at the Shortfall Interest Rate from the date the Product Sales Milestone Payment Date should have occurred (if the Company had given notice of achievement of such Product Sales Milestone pursuant to the terms of this CVR Agreement), as applicable, to the date of actual payment (such amount including interest being the “CVR Shortfall”). The Company shall pay the CVR Shortfall to the CVR Holders of record as of a date that is three (3) Business Days prior to a Payment Date selected by the Company, which Payment Date must be within sixty (60) days of the date the Acting Holders deliver to the Company the Independent Accountant’s written report (the “Shortfall Report”). The decision of such Independent Accountant shall be final, conclusive and binding on the Company and the Holders, shall be nonappealable and shall not be subject to further review.

(c) Each Person seeking to receive information from the Company in connection with a review or audit shall enter into, and shall cause its accounting firm to enter into, a reasonable and mutually satisfactory confidentiality agreement with the Company obligating such party to retain all such financial information disclosed to such party in confidence pursuant to such confidentiality agreement and not use such information for any purpose other than the completion of such review or audit.

(d) The Company shall not, and shall cause its Affiliates not to, enter into any license or distribution agreement with any third party (other than the Company or its Affiliates) with respect to a Product unless such agreement contains provisions that would allow any Independent Accountant appointed pursuant to this SECTION 7.6 such access to the records of the other party to such license or distribution agreement as may be reasonably necessary to perform its duties pursuant to this SECTION 7.6; provided that the Company and its Affiliates shall not be required to amend any Existing Licenses. The Parties agree that, if the Company or its Affiliates have exercised audit rights under any license or distribution agreement prior to the Acting Holders’ request for an audit under this SECTION 7.6 and under such license or distribution agreement the Company and its Affiliates cannot request another audit, the results of the Company’s prior audit of such licensee or distributor shall be used for purposes of the audit requested by the Acting Holders under this SECTION 7.6 and that the Company shall not have any further obligation to provide access to an Independent Accountant with respect to such licensee until such time as the Company may again exercise its rights of audit under the license agreement with such licensee.

SECTION 7.7 Listing of CVRs. The Company hereby covenants and agrees it shall use its commercially reasonable efforts to maintain a listing for trading on the Nasdaq Global Select Market, Nasdaq Global Market, or other national securities exchange for so long as any CVRs remain Outstanding.

SECTION 7.8 Product Transfer. Subject to ARTICLE 9, so long as the Securities remain Outstanding, the Company and its Affiliates may not, directly or indirectly, by a sale or swap of assets, merger, reorganization, joint venture, lease, license, or any other transaction or arrangement, sell, transfer, convey or otherwise dispose of their respective rights in and to a Product to a third party (other than the Company or its Affiliates) (such transaction, a “Product

Disposition Transaction”), unless (a) the Company (or its successor including, if applicable, a Person to whom all of the Company’s and its Subsidiaries’ interests in the relevant Product are transferred) shall agree to remain subject to the obligations hereunder to make any Product Sales Milestone Payments and the Approval Milestone Payment if and when such a payment is due in accordance with the terms of this CVR Agreement and (b) at all times after the closing of such Product Disposition Transaction and prior to the Termination Date the gross amounts invoiced for Products by the applicable transferee will be reflected in the Product Sales in accordance with the terms hereunder (with the transferee substituted for the Company for the purposes of the definition of “Product Sales”) as if such transferee was the Company and the agreement for such Product Disposition Transaction requires the transferee to comply with the covenants in this SECTION 7.8 and in SECTION 7.6 hereof to the same extent as the Company. For purposes of clarification, this SECTION 7.8 shall not apply to sales of a Product made by the Company or its Affiliates or ordinary course licensing arrangements between the Company and its Affiliates, on the one hand, and third party licensees, distributors and contract manufacturers, on the other hand, entered into in the ordinary course of business for purposes of developing, manufacturing, distributing and/or selling such Product and for which the gross amounts invoiced for sales of such Product by the applicable third party licensee, distributor or contract manufacturer shall be reflected in Product Sales in accordance with the terms of this CVR Agreement.

SECTION 7.9 Milestones.

(a) Subject to SECTIONS 7.9(b), (c) and (d) below, the Company, directly or through its Affiliates, licensees and/or other contractors, shall use Diligent Efforts to achieve (i) the Approval Milestone and (ii) the Product Sales Milestones through sales of Marketed Products.

(b) The Company shall have no obligation to pursue the Approval Milestone if the FDA issues an order under 21 CFR 814.45 denying FDA Approval of the AUGMENT PMA. Further, and for the avoidance of doubt, in the event the FDA requires any additional clinical efficacy trial(s), post-marketing study(ies) (other than customary post-approval patient registries) or otherwise requests additional information that cannot be derived from BioMimetic’s completed clinical studies, the Company, its Affiliates and/or licensees will not be required to undertake any of the foregoing, and any election by the Company, its Affiliates and/or licensees not to do so will not be deemed a failure to exercise Diligent Efforts under this Agreement. For purposes of the foregoing sentence, additional safety trials such as pharmacokinetic studies and similar studies with non-efficacy based endpoints that are reasonably capable of being performed in less than eighteen (18) months will not be considered clinical efficacy trials.

(c) The Company’s obligation to use Diligent Efforts to achieve the Product Sales Milestones with respect to AUGMENT Bone Graft do not require the Company, its Affiliates and/or licensees to seek or obtain approval to market and sell AUGMENT Bone Graft (i) in any jurisdiction other than the United States, nor (ii) for any indication other than the indications approved by the FDA in the first FDA Approval of AUGMENT Bone Graft (assuming any such approval is obtained).

(d) Except as expressly set forth in SECTION 7.9(a) above with respect to AUGMENT Bone Graft, the Company shall have no obligation (i) to seek new or expanded regulatory approvals for any Product, (ii) to develop or introduce new Products or (iii) to commercialize any Product in any jurisdiction where such Product was not legally commercialized as of the date of this CVR Agreement. No failure of the Company, its Affiliates and/or licensees to do any of the foregoing will be deemed a failure to use Diligent Efforts hereunder. Further, and without in any way inferring that the application of Diligent Efforts would otherwise bar the Company, its Affiliates and/or licensees from electing in good faith to discontinue the marketing and sale of a Product, it is understood and agreed that if the Company, or any of its Affiliates or licensees, elects for any reason to suspend or discontinue the marketing and sale of AUGMATRIX Bone Graft in any jurisdiction (or in all jurisdictions), such decision shall not be deemed a failure by the Company to use Diligent Efforts hereunder.

SECTION 7.10 Notice of Breach. The Company shall file with the Trustee written notice of the occurrence of any Breach or other breach under this CVR Agreement within five (5) Business Days of its becoming aware of any such Breach or other breach.

SECTION 7.11 Non-Use of Name. Neither the Trustee nor the Holders shall use the name, trademark, trade name or logo of the Company, its Affiliates, or their respective employees in any publicity or news release relating to this CVR Agreement or its subject matter, without the prior express written permission of the Company, other than (in the case of the name of the Company, its Affiliates, or their respective employees) with respect to a dispute pursuant to this CVR Agreement between any of the Holders, the Trustee, the Company or its Affiliates.

ARTICLE 8

REMEDIES OF THE TRUSTEE AND HOLDERS IN THE EVENT OF BREACH

SECTION 8.1 Breach Defined; Waiver of Breach. “Breach” with respect to the Securities, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Breach and whether it shall be voluntary or involuntary or be effected by operation of Law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(a) failure to pay all or any part of any CVR Payment after a period of ten (10) Business Days after such CVR Payment shall become due and payable on a Payment Date or otherwise; or

(b) material breach in the performance, or breach in any material respect, of any covenant or warranty of the Company in respect of the Securities (other than a covenant or warranty in respect of the Securities, a breach in whose performance or other breach is elsewhere in this SECTION 8.1 specifically dealt with), and continuance of such breach for a period of ninety (90) days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Acting Holders, a written notice specifying such breach and requiring it to be remedied and stating that such notice is a “Notice of Breach” hereunder; or

(c) a court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar Law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of ninety (90) consecutive days; or

(d) the Company shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar Law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such Law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property, or make any general assignment for the benefit of creditors.

Except where authorization and/or appearance of each of the Holders is required by applicable Law, if a Breach described above occurs and is continuing, then either the Trustee by notice in writing to the Company, or the Trustee upon the written request of the Acting Holders by notice in writing to the Company and to the Trustee, may, as provided in SECTION 8.2, bring suit to protect the rights of the Holders, including to obtain payment for any amounts then due and payable, which amounts shall bear interest at the Breach Interest Rate from the date such amounts were due and payable until payment is made to the Trustee.

The foregoing provisions, however, are subject to the condition that if, at any time after the Trustee shall have begun such suit, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all amounts which shall have become due and payable (with interest upon such overdue amount at the Breach Interest Rate to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred and all advances made, by the Trustee, and if any and all Breaches under this CVR Agreement shall have been cured, waived or otherwise remedied as provided herein, then and in every such case Holders of at least a majority of the Outstanding CVRs, by Act of said Holders delivered to the Company and the Trustee, may waive all breaches with respect to the Securities, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent breach or shall impair any right consequent thereof.

SECTION 8.2 Collection by the Trustee; the Trustee May Prove Payment Obligations. The Company covenants that in the case of any failure to pay all or any part of the Securities when the same shall have become due and payable, whether at a Payment Date or otherwise, then upon demand of the Trustee, the Company shall pay to the Trustee for the benefit of the Holders of the Securities the whole amount that then shall have become due and payable on all Securities (with interest from the date due and payable to the date of such payment upon the overdue amount at the Breach Interest Rate); and in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor Trustee, their respective agents, attorneys and counsel, and any expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of the Trustee’s gross negligence or bad faith.

The Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this CVR Agreement or in aid of the exercise of any power granted herein, or to enforce any other remedy.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at Law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon such Securities and collect in the manner provided by Law out of the property of the Company or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to be payable.

In any judicial proceedings relative to the Company or other obligor upon the Securities, irrespective of whether any amount is then due and payable with respect to the Securities, the Trustee is authorized:

(a) to file and prove a claim or claims for the whole amount owing and unpaid in respect of the Securities, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of the Trustee’s gross negligence or bad faith) and of the Holders allowed in any judicial proceedings relative to the Company or other obligor upon the Securities, or to their respective property;

(b) unless prohibited by and only to the extent required by applicable Law, to vote on behalf of the Holders in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or Person performing similar functions in comparable proceedings; and

(c) to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Holders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Holders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of the Trustee’s gross negligence or bad faith, and all other amounts due to the Trustee or any predecessor Trustee pursuant to SECTION 4.6. To the extent that such payment of reasonable compensation, expenses, disbursements, advances and other amounts out

of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, moneys, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or safeguard arrangement or otherwise.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Holder any plan of reorganization, safeguard arrangement, adjustment or composition affecting the Securities, or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person.

All rights of action and of asserting claims under this CVR Agreement, or under any of the Securities, may be enforced by the Trustee without the possession of any of the Securities or the production thereof and any trial or other proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders.

In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this CVR Agreement to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders, and it shall not be necessary to make any Holders of such Securities parties to any such proceedings (unless required by applicable Law).

SECTION 8.3 Application of Proceeds. Any monies collected by the Trustee pursuant to this ARTICLE 8 in respect of any Securities shall be applied in the following order at the date or dates fixed by the Trustee upon presentation of the several Securities in respect of which monies have been collected and stamping (or otherwise noting) thereon the payment in exchange for the presented Securities if only partially paid or upon surrender thereof if fully paid:

FIRST: To the payment of costs and expenses in respect of which monies have been collected, including reasonable compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of the Trustee’s gross negligence or willful misconduct, and all other amounts due to the Trustee or any predecessor Trustee pursuant to SECTION 4.6;

SECOND: To the payment of the whole amount then owing and unpaid upon all the Securities, with interest at the Breach Interest Rate on all such amounts, and in case such monies shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities, then to the payment of such amounts without preference or priority of any security over any other Security, ratably to the aggregate of such amounts due and payable; and

THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

SECTION 8.4 Suits for Enforcement. In case a Breach has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this CVR Agreement by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights (unless authorization and/or appearance of each of the Holders is required by applicable Law), either at Law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this CVR Agreement or in aid of the exercise of any power granted in this CVR Agreement or to enforce any other legal or equitable right vested in the Trustee by this CVR Agreement or by Law.

SECTION 8.5 Restoration of Rights on Abandonment of Proceedings. In case the Trustee or any Holder shall have proceeded to enforce any right under this CVR Agreement and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then and in every such case the Company and the Trustee and the Holders shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the Holders shall continue as though no such proceedings had been taken.

SECTION 8.6 Limitations on Suits by Holders. Subject to the right of the Acting Holders under SECTION 7.6 and the rights of the Holders under SECTION 8.7, no Holder of any Security shall have any right by virtue or by availing of any provision of this CVR Agreement to institute any action or proceeding at Law or in equity or in bankruptcy or otherwise upon or under or with respect to this CVR Agreement, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless: (i) such Holder previously shall have given to the Trustee written notice of breach and of the continuance thereof, as hereinbefore provided; (ii) the Acting Holders shall have made written request upon the Trustee to institute such action or proceedings in its own name as trustee hereunder; and (iii) such Holder shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for fifteen (15) days after its receipt of such notice and request shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to SECTION 8.9; it being understood and intended, and being expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee, that no one or more Holders of Securities shall have any right in any manner whatever by virtue or by availing of any provision of this CVR Agreement to effect, disturb or prejudice the rights of any other such Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this CVR Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities. For the protection and enforcement of the provisions of this SECTION 8.6, each and every Holder and the Trustee shall be entitled to such relief as can be given either at Law or in equity.

SECTION 8.7 Unconditional Right of Holders to Institute Certain Suits. Notwithstanding any other provision in this CVR Agreement and any provision of any Security, the right of any Holder of any Security to receive payment of the amounts payable in respect of such Security on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 8.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Breach.

(a) Except as provided in SECTION 8.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by Law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at Law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

(b) No delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Breach occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Breach or an acquiescence therein; and, subject to SECTION 8.6, every power and remedy given by this CVR Agreement or by Law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

SECTION 8.9 Control by Holders.

(a) The Holders of at least a majority of the Outstanding CVRs shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any power conferred on the Trustee with respect to the Securities by this CVR Agreement; provided that such direction shall not be otherwise than in accordance with Law and the provisions of this CVR Agreement; and provided further that (subject to the provisions of SECTION 4.1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee, or a committee of directors or Responsible Officers of the Trustee shall determine that the action or proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities not joining in the giving of said direction.

(b) Nothing in this CVR Agreement shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Holders.

SECTION 8.10 Waiver of Past Breaches.

(a) In the case of a breach or a Breach specified in clause (b), (c) or (d) of SECTION 8.1, the Holders of at least a majority of the Outstanding CVRs may waive any such Breach, and its consequences except a breach in respect of a covenant or provisions hereof which cannot be modified or amended without the consent of the Holder of each Security affected. In the case of any such waiver, the Company, the Trustee and the Holders of the Securities shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other breach or impair any right consequent thereon.

(b) Upon any such waiver, such breach shall cease to exist and be deemed to have been cured and not to have occurred, and any Breach arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this CVR Agreement; but no such waiver shall extend to any subsequent or other Breach or other breach of any kind or impair any right consequent thereon.

SECTION 8.11 The Trustee to Give Notice of Breach, But May Withhold in Certain Circumstances. The Trustee shall transmit to the Holders, as the names and addresses of such Holders appear on the Security Register (as provided under Section 313(c) of the Trust Indenture Act, if applicable), notice by mail of all breaches which have occurred and are known to the Trustee, such notice to be transmitted within ninety (90) days after the occurrence thereof, unless such breaches shall have been cured before the giving of such notice (the term “breach” for the purposes of this SECTION 8.11 being hereby defined to mean any event or condition which is, or with notice or lapse of time or both would become, a Breach); provided that, except in the case of a failure to pay the amounts payable in respect of any of the Securities, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders; and provided, however, that in the case of any breach of the character specified in SECTION 8.1(b) with respect to the Securities, no notice to Holders shall be given until at least thirty (30) days after the occurrence thereof.

SECTION 8.12 Right of Court to Require Filing of Undertaking to Pay Costs. All Parties to this CVR Agreement agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this CVR Agreement or in any suit against the Trustee for any action taken, suffered or omitted by it as the Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including attorneys’

fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this SECTION 8.12 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder or group of Holders holding in the aggregate more than ten percent (10%) of the Securities Outstanding or to any suit instituted by any Holder for the enforcement of the payment of any Security on or after the due date expressed in such Security.

SECTION 9.1 Successor Person Substituted.

(a) In case of a consolidation or merger with a wholly-owned Subsidiary or any other Person, or a transfer or sale to a Person of all or substantially all of the assets or business of Company related to the Products, and following the assumption of this CVR Agreement by such successor Person, such successor Person shall succeed to and be substituted for the Company with the same effect as if it had been named herein. Such successor Person may cause to be signed, and may issue either in its own name or in the name of the Company prior to such succession any or all of the Securities issuable hereunder, in the case of Global Securities, which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this CVR Agreement prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered to the Trustee for authentication, and any Securities which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Securities so issued shall in all respects have the same legal rank and benefit under this CVR Agreement as the Securities theretofore or thereafter issued in accordance with the terms of this CVR Agreement as though all of such Securities had been issued at the date of the execution hereof.

(b) In case of any such consolidation or merger or sale described in SECTION 9.1(a), such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. The successor Person to such consolidation or merger may satisfy the obligations of SECTION 5.4(a)(i) and (ii) by providing copies of such successor entity’s Exchange Act Documents in the case of SECTION 5.4(a)(i) or such successor entity’s financial information in the case of SECTION 5.4(a)(ii).

SECTION 9.2 Opinion of Counsel to the Trustee. The Trustee, subject to the provisions of SECTIONS 4.1 and 4.2, shall receive an Officer’s Certificate and Opinion of Counsel, prepared in accordance with SECTIONS 1.2 and 1.3, as conclusive evidence that any such consolidation, merger, sale or conveyance, and any such assumption, and any such liquidation or dissolution, complies with the applicable provisions of this CVR Agreement, and if a supplemental agreement is required in connection with such transaction, such supplemental agreement complies with this ARTICLE 9 and that there has been compliance with all conditions precedent herein provided for or relating to such transaction.

All covenants, provisions and agreements in this CVR Agreement by or for the benefit of the Company, the Trustee or the Holders shall bind and inure to the benefit of their respective successors, assigns, heirs and personal representatives, whether so expressed or not. The Company may assign this CVR Agreement without the prior written consent of the other Parties to this CVR Agreement (i) to one or more of its direct or indirect Subsidiaries or (ii) in connection with the transfer or sale of all or substantially all of the assets or business of the Company related to the Products, or in the event of the Company’s merger or consolidation , provided, however, that in the event of any such assignment the Company (or its successor) agrees in writing to remain subject to the obligations and covenants hereunder to make any Product Sales Milestone Payments and the Approval Milestone Payment when such a payment is due in accordance with the terms of this CVR Agreement.

ARTICLE 10

SUBORDINATION

SECTION 10.1 Agreement to Subordinate. The Company agrees, and each Holder by accepting a Security hereunder agrees, that the CVR Payments, all other obligations under this CVR Agreement and the Securities and any rights or claims relating thereto (collectively, the “Junior Obligations”) are subordinated in right of payment, to the extent and in the manner provided in this ARTICLE 10 to the prior payment in full in money or money’s worth of all Senior Obligations of the Company (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of such Senior Obligations.

SECTION 10.2 Liquidation; Dissolution; Bankruptcy. Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of creditors or any marshaling of the Company’s assets and liabilities:

(a) holders of Senior Obligations will be entitled to receive payment in full in money or money’s worth of all Senior Obligations of the Company (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Obligation, whether or not permitted under such bankruptcy proceedings) before the Holders will be entitled to receive any payment of any kind with respect to the Junior Obligations (other than securities of the Company or debt of the Company that is subordinated to the Senior Obligations on terms at least as favorable to holders of Senior Obligations as this ARTICLE 10 (“Permitted Junior Securities”)); and

(b) until all Senior Obligations of the Company (as provided in clause (a) above) are paid in full in money or money’s worth, any distribution to which Holders would be entitled but for this ARTICLE 10 (other than Permitted Junior Securities) will be made to holders of Senior Obligations of the Company, as their interests may appear.

SECTION 10.3 When Distribution Must be Paid Over.

(a) In the event that the Trustee or any Holder receives any payment of any Junior Obligations (other than Permitted Junior Securities) at a time when the Trustee or such Holder has actual knowledge that such payment is prohibited by this ARTICLE 10 , such payment will be held by the Trustee or such Holder, in trust for the benefit of, and will be paid forthwith over and delivered, upon written request, to, the holders of Senior Obligations of the Company as their interests may appear or their representative under the agreement, indenture or other document (if any) pursuant to which such Senior Obligations may have been issued, as their respective interests may appear, for application to the payment of all such Senior Obligations remaining unpaid to the extent necessary to pay such Senior Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Obligations.

(b) With respect to the holders of Senior Obligations, the Trustee undertakes to perform only those obligations on the part of the Trustee as are specifically set forth in this ARTICLE 10, and no implied covenants or obligations with respect to the holders of Senior Obligations will be read into this CVR Agreement against the Trustee. The Trustee will not be deemed to owe any fiduciary duty to the holders of Senior Obligations, and will not be liable to any such holders if the Trustee pays over or distributes to or on behalf of Holders or the Company or any other Person money or assets to which any holders of Senior Obligations are then entitled by virtue of this ARTICLE 10, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee.

SECTION 10.4 Notice by Company. The Company will promptly notify the Trustee of any facts known to the Company that would cause a payment of any Junior Obligations to violate this ARTICLE 10, but failure to give such notice will not affect the subordination of the Junior Obligations to the Senior Obligations as provided in this ARTICLE 10.

SECTION 10.5 Subrogation. After all Senior Obligations are paid in full in money or money’s worth and until the Junior Obligations are paid in full, Holders will be subrogated to the rights of holders of Senior Obligations to receive distributions applicable to Senior Obligations to the extent that distributions otherwise payable to the Holders have been applied to the payment of Senior Obligations. The Holders by accepting the Securities acknowledge that to the extent that the Senior Obligations are determined to be unenforceable, or the Senior Obligations are subordinated to other obligations of the Company, such subrogation rights may be impaired.

SECTION 10.6 Relative Rights. This ARTICLE 10 defines the relative rights of Holders and holders of Senior Obligations. Nothing in this CVR Agreement will:

(a) impair, as between the Company and Holders, the obligations of the Company under this CVR Agreement and the Securities;

(b) affect the relative rights of Holders and creditors of the Company other than their rights in relation to holders of Senior Obligations; or

(c) prevent the Trustee or any Holder from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders of Senior Obligations to receive distributions and payments otherwise payable to Holders under this ARTICLE 10.

If the Company fails because of this ARTICLE 10 to pay any amounts due in respect of the Securities on a due date in violation of SECTION 3.1(c) or SECTION 3.1(d), the failure is still an Event of Default.

SECTION 10.7 Subordination May Not be Impaired by the Company. No right of any holder of Senior Obligations to enforce the subordination of the Junior Obligations may be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company or any Holder to comply with this CVR Agreement.

SECTION 10.8 Distribution or Notice to the Representative. Whenever a distribution is to be made or a notice given to holders of Senior Obligations, the distribution may be made and the notice given to their representative in accordance with the terms of the instrument or other agreement governing such Senior Obligations. Upon any payment or distribution of assets of the Company referred to in this ARTICLE 10, the Trustee and the Holders will be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Obligations and other obligations of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this ARTICLE 10.

SECTION 10.9 Rights of the Trustee. Notwithstanding the provisions of this ARTICLE 10 or any other provision of this CVR Agreement, the Trustee will not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee may continue to make payments on the Securities, unless the Trustee has received at its address for notice specified in SECTION 1.5 at least five (5) Business Days prior to the date of such payment written notice of facts that would cause the payment of any Junior Obligations to violate this ARTICLE 10. Only the Company or a representative of Senior Obligations may give the notice. Nothing in this ARTICLE 10 will impair the claims of, or payments to, the Trustee under or pursuant to SECTION 4.6 hereof. The Trustee in its individual or any other capacity may hold Senior Obligations with the same rights it would have if it were not the Trustee.

SECTION 10.10 Authorization to Effect Subordination. Each Holder, by the Holder’s acceptance of the Securities, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this ARTICLE 10, and appoints the Trustee to act as such Holder’s attorney-in-fact for any and all such purposes. If the Trustee (or any other Person acting on behalf of and at the direction of the Majority Holders) does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in SECTION 8.2 hereof at least thirty (30) days before the expiration of the time to file such claim, the representatives of the Senior Obligations are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities.

SECTION 10.11 Amendments. The provisions of this ARTICLE 10 are expressly made for the benefit of the holders from time to time of the Senior Obligations, and may not be amended or modified without the written consent of the representatives of the holders of all Senior Obligations.

ARTICLE 11

PURCHASE OF SECURITIES UPON CVR FAILURE EVENT

SECTION 11.1 Notice of Trustee. In the event that a Failure Purchase Eligibility Date has occurred and the Company elects to purchase the Securities pursuant to the provisions of SECTION 11.5 hereof (a “Failure Purchase”), it shall furnish to the Trustee, at least thirty (30) days (unless a shorter period shall be agreed to by the Trustee) but not more than sixty (60) days before the date on which the Company proposes to consummate the Failure Purchase (any such date, a “Failure Purchase Date”) (but in any event prior to the notice provided pursuant to SECTION 11.2 hereof), an Officer’s Certificate (a “Failure Purchase Offer”) setting forth (i) the clause of this CVR Agreement pursuant to which the Failure Purchase shall occur, (ii) the Failure Purchase Date, and (iii) the Failure Purchase Price, determined in accordance with SECTION 11.5 hereof.

SECTION 11.2 Notice of Failure Purchase. At least thirty (30) days but not more than sixty (60) days before a Failure Purchase Date, the Company shall mail or cause to be mailed, a notice of Failure Purchase to each Holder at its registered address (the “Failure Purchase Notice”) and shall publicly disclose the election of the Failure Purchase and the information required to be contained in the Failure Purchase Notice pursuant to this SECTION 11.2. The Failure Purchase Notice shall identify the number of Securities Outstanding and shall state:

(a)

the Failure Purchase Date;

(b) the Failure Purchase Price;

(d) that Securities must be surrendered to the Paying Agent to collect the Failure Purchase Price;

(e) that, unless the Company fails to make payment of the Failure Purchase Price, all right, title and interest in and to the Securities and any CVR Payment or any other amounts due under this CVR Agreement, if any, on Securities called for Failure Purchase ceases to accrue on and after the Failure Purchase Date;

(f) the clause of this CVR Agreement pursuant to which the Failure Purchase shall occur; and

(g) that no representation is made as to the correctness or accuracy of the CUSIP and ISIN number, if any, listed in such notice or printed on the Securities.

At the Company’s request, the Trustee shall give the Failure Purchase Notice in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee at least forty five (45) days (unless a shorter period shall be agreed to by the Trustee) but not more than sixty (60) days prior to the Failure Purchase Date, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

SECTION 11.3 Effect of Failure Purchase Notice. Once the Failure Purchase Notice is mailed in accordance with SECTION 11.2 hereof, the Securities shall become irrevocably due and payable on the Failure Purchase Date at the Failure Purchase Price. A Failure Purchase Notice shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give a particular Holder his or her Failure Purchase Notice, or any defect in such notice, shall not affect the validity of the proceedings for the Failure Purchase.

SECTION 11.4 Deposit of Failure Purchase Price. On or one (1) Business Day prior to the Failure Purchase Date, the Company shall deposit with the Trustee or with the paying agent (if different from the Trustee) money sufficient to pay the Failure Purchase Price of all Securities Outstanding on that date. The Trustee or the paying agent shall promptly return to the Company any money deposited with the Trustee or the paying agent by the Company in excess of the amounts necessary to pay the Failure Purchase Price of all Securities Outstanding.

If the Company complies with the provisions of the preceding paragraph, on and after the Failure Purchase Date, all right, title and interest of a Holder to any CVR Payment, if any, shall cease to accrue on the Securities. If any Security called for Failure Purchase shall not be so paid upon surrender for Failure Purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid Failure Purchase Price from the Failure Purchase Date, until such Failure Purchase Price is paid at the Shortfall Interest Rate.

SECTION 11.5 Failure Purchase by the Company. The Company may, for a period of sixty (60) days after any Failure Purchase Eligibility Date, issue the Failure Purchase Notice in accordance with SECTION 11.2. Upon issuance of the Failure Purchase Notice and in compliance with the other provisions of this ARTICLE 10, the Company shall, on the Failure Purchase Date specified in such Failure Purchase Notice, purchase and cancel all (but not less than all) of the outstanding Securities at a cash price equal to 115% of the volume weighted average price paid per Security for all Securities traded over the forty-five (45) trading days prior to the fifth (5th) trading day prior to the date of the Failure Purchase Notice (the “Failure Purchase Price”). If the Company has not issued the Failure Purchase Notice within such sixty (60) day period after the occurrence of a Failure Purchase Eligibility Date, it shall not be entitled to issue a Failure Purchase Notice and purchase and cancel the Securities until the next instance in which a Failure Purchase Eligibility Date occurs.

IN WITNESS WHEREOF, the Parties hereto have caused this CVR Agreement to be duly executed, all as of the day and year first above written.
