ARTICLE II

CONTINGENT VALUE RIGHTS

Section 2.1 CVRs. The CVRs represent the rights of Holders (granted to Initial Holders as a consequence of the Offer and the Merger pursuant to the terms of the Merger Agreement) to receive a one-time contingent cash payment of the Milestone Payment pursuant to this Agreement.

Section 2.2 Nontransferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted CVR Transfer. Any attempted sale, assignment, transfer, pledge, encumbrance or disposition of CVRs, in whole or in part, in violation of this Section 2.2 shall be void ab initio and of no effect.

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

a) The CVRs will not be evidenced by a certificate or other instrument.

b) The Rights Agent will keep a register (the “CVR Register”) for the purpose of (i) identifying the Holders of CVRs and (ii) registering CVRs and Permitted CVR Transfers thereof. The CVR Register will initially show one position for Cede & Co. representing all the Shares held by DTC on behalf of the street holders of the Shares tendered by such holders in the Offer or held by such holders as of immediately prior to the Effective Time. The Rights Agent will have no responsibility whatsoever directly to the street name holders with respect to transfers of CVRs unless and until such CVRs are transferred into the name of such street name holders in accordance with Section 2.2. With respect to any payments to be made under Section 2.4 below, the Rights Agent will accomplish the payment to any former street name holders of Shares by sending one lump payment to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders. Upon request of a Holder, the Rights Agent will make available to such Holder a list of the other Holders, the number of CVRs held by each Holder and the contact information maintained by the Rights Agent with respect to each Holder.

c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer, in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative duly authorized in writing, or the Holder’s survivor (with written documentation evidencing such person’s status as the Holder’s survivor), and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice, the Rights Agent will, subject to its reasonable determination that the transfer instrument is in proper form and the transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the CVRs in the CVR Register. As a condition of such transfer, Parent and Rights Agent may require a transferring Holder or its transferee to pay to the applicable Governmental Body any transfer, stamp or other similar Tax or governmental charge that is imposed in connection with any such registration of transfer. The Rights Agent shall have no duty or obligation to take any action under any section of this Agreement that requires the payment by a Holder of a CVR of such applicable Taxes or charges unless and until the Rights Agent is reasonably satisfied that all such Taxes or charges have been paid or that such Taxes or charges are not applicable. All duly transferred CVRs registered in the CVR Register will be the valid obligations of Parent and Purchaser and will entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR will be valid until registered in the CVR Register in accordance with this Agreement.

d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent will promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures; Notices.

a) If the Milestone is attained on or prior to the Expiration Date, then on or prior to the Milestone Payment Date, (i) Parent shall deliver to the Rights Agent (x) written notice indicating that the Milestone has been achieved (the “Milestone Notice”) and an Officer’s Certificate certifying the date of such achievement and that the Holders are entitled to receive the Milestone Payment, (y) any letter of instruction reasonably required by the Rights Agent and (ii) Purchaser shall deliver to the Rights Agent the payment required by Section 4.2.

b) The Rights Agent will promptly, and in any event within ten (10) Business Days after receipt of the Milestone Notice as well as any letter of instruction reasonably required by the Rights Agent, send each Holder at its registered address a copy of the Milestone Notice and pay the Milestone Payment Amount to each of the Holders by check mailed to the address of each Holder as reflected in the CVR Register as of the close of business on the date of the Milestone Notice.

c) Parent and its Affiliates (including Purchaser) and the Rights Agent shall be entitled to deduct and withhold, from the Milestone Payment Amount or any other amounts otherwise payable pursuant to this Agreement such amounts as may be required to be deducted and withheld therefrom under applicable Law. With respect to Holders who received Equity Award CVRs, any such withholding may be made, or caused to be made, by Parent through the Surviving Corporation’s or its Affiliates’ (including Purchaser’s) payroll system or any successor payroll system. Prior to making (or causing to be made) any such Tax deduction or withholding, Parent shall instruct the Rights Agent to provide the opportunity for the Holder to provide IRS Forms W-9 or W-8, as applicable, or any other reasonably appropriate forms or information from Holders in order to avoid or reduce such withholding amount. The Rights Agent shall promptly and timely remit, or cause to be remitted, any amounts withheld in respect of Taxes to the appropriate Governmental Body. To the extent any amounts are so deducted and withheld,

such amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of whom such deduction and withholding was made. The parties intend that each Equity Award CVR is exempt from or in compliance with Section 409A of the Code, and this Agreement shall be interpreted and administered in accordance therewith. None of the parties to this Agreement nor any of their employees, directors or representatives shall have any liability to a Holder or transferee or other Person in respect of Section 409A of the Code.

d) Any portion of the Milestone Payment Amount that remains undistributed to a Holder six (6) months after the date of the delivery of the Milestone Notice will be delivered by the Rights Agent to Parent or Purchaser, upon demand, and any Holder will thereafter look only to Parent and Purchaser for payment of the Milestone Payment Amount, without interest, but such Holder will have no greater rights against Parent and Purchaser than those accorded to general unsecured creditors of Parent and Purchaser under applicable Law.

e) None of Parent, any of its Affiliates (including Purchaser) or the Rights Agent will be liable to any person in respect of the Milestone Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If, despite Purchaser’s and/or the Rights Agent’s commercially reasonable efforts to deliver the Milestone Payment Amount to the applicable Holder, the Milestone Payment Amount has not been paid prior to two (2) years after the Milestone Payment Date (or immediately prior to such earlier date on which the Milestone Payment Amount would otherwise escheat to or become the property of any Governmental Body), the Milestone Payment Amount will, to the extent permitted by applicable Law, become the property of Purchaser, free and clear of all claims or interest of any person previously entitled thereto. In addition to and not in limitation of any other indemnity obligation herein, Purchaser agrees to indemnify and hold harmless Rights Agent with respect to any liability, penalty, cost or expense Rights Agent may incur or be subject to in connection with transferring such property to Purchaser.

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent or any of its Affiliates.

a) The CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable on the CVRs to any Holder.

b) The CVRs will not represent any equity or ownership interest in Parent, any constituent corporation party to the Merger Agreement or any of their respective Affiliates.

c) Neither Parent and its directors and officers nor Purchaser and its directors and officers will be deemed to have any fiduciary or similar duties to any Holder by virtue of this Agreement.

Section 2.6 Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Purchaser without consideration therefor, which a Holder may effect via delivery of a written abandonment notice to Parent. Nothing in this Agreement shall prohibit Parent or any of its Affiliates (including Purchaser) from offering to acquire or acquiring any CVRs for consideration from the Holders, in private transactions or otherwise, in its sole discretion. Any CVRs acquired by Parent or any of its Affiliates (including Purchaser) shall be automatically deemed extinguished and no longer outstanding for purposes of the definition of Acting Holders and Article V and Section 6.3 hereunder.

b) whenever the Rights Agent will deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Rights Agent may rely upon an Officer’s Certificate, which certificate shall be full authorization and protection to the Rights Agent, and the Rights Agent shall, in the absence of bad faith, gross negligence or willful misconduct on its part, incur no liability and be held harmless by Parent for or in respect of any action taken, suffered or omitted to be taken by it under the provisions of this Agreement in reliance upon such certificate;

c) the Rights Agent may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of counsel will be full and complete authorization and protection to the Rights Agent and the Rights Agent shall be held harmless by Parent in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

h) Parent agrees to indemnify Rights Agent for, and hold Rights Agent harmless against, any loss, liability, claim, demands, suits or expense arising out of or in connection with Rights Agent’s duties under this Agreement, including the reasonable costs and expenses of defending Rights Agent against any claims, charges, demands, suits or loss, unless such loss has been determined by a court of competent jurisdiction to be a result of Rights Agent’s gross negligence, bad faith or willful or intentional misconduct;

j) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

a) Rights Agent may resign at any time by giving written notice thereof to Parent specifying a date when such resignation will take effect, which notice will be sent at least sixty (60) days prior to the date so specified but in no event will such resignation become effective until a successor Rights Agent has been appointed. Parent has the right to remove Rights Agent at any time by specifying a date when such removal will take effect but no such removal will become effective until a successor Rights Agent has been appointed. Notice of such removal will be given by Parent to Rights Agent, which notice will be sent at least sixty (60) days prior to the date so specified.

b) If the Rights Agent provides notice of its intent to resign, is removed pursuant to Section 3.3(a) or becomes incapable of acting, Parent will as soon as is reasonably possible, appoint a qualified successor Rights Agent who, unless otherwise consented to in writing by the Acting Holders, shall be a stock transfer agent of national reputation or the corporate trust department of a commercial bank. The successor Rights Agent so appointed will, forthwith upon its acceptance of such appointment in accordance with Section 3.4, become the successor Rights Agent.

c) Parent will give notice of each resignation and each removal of a Rights Agent and each appointment of a successor Rights Agent by mailing written notice of such event by first-class mail to the Holders as their names and addresses appear in the CVR Register.

Where this Agreement provides for notice to Holders, such notice will be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the Holder’s address as it appears in the CVR Register, not later than the latest date, and not earlier than the earliest date, if any, prescribed for the giving of such notice. 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 will affect the sufficiency of such notice with respect to other Holders.

Section 6.3 Successors and Assigns. Each of Parent and Purchaser may assign any or all of its rights, interests and obligations hereunder in its sole discretion and without the consent of any other party, (a) to any controlled Affiliate of Parent, but only for so long as it remains a controlled Affiliate of Parent, (b) to any purchaser, transferee, licensee, or sublicensee that is a company in the pharmaceutical industry of substantially all of the Intellectual Property and other rights (including, without limitation, all data, marketing authorizations and applications for marketing authorization), assets, rights, powers, privileges and Contracts , in each case, (x) held, owned or entered into by the Parent or its Subsidiaries immediately after the Effective Time and (y) necessary for the production, development or sale of the CVR Products; (c) in compliance with Section 4.3(b); (d) otherwise with the prior written consent of the Acting Holders, any other Person (any permitted assignee under clause (a), (b), (c) or (d), an “Assignee”), in each case provided that the Assignee agrees to assume and be bound by all of the terms of this Agreement. Any Assignee may thereafter assign any or all of its rights, interests and obligations hereunder in the same manner as Parent or Purchaser, as applicable, pursuant to the prior sentence. In connection with any assignment to an Assignee described in clause (a) above in this Section 6.3 and clause (b) above in this Section 6.3, each of Parent or Purchaser, as applicable, (and the other assignor) shall agree to remain liable for the performance by each Assignee (and such other assignor, if applicable) of all obligations of Parent or Purchaser, as applicable, hereunder with such Assignee substituted for Parent or Purchaser, as applicable, under this Agreement. This Agreement will be binding upon, inure to the benefit of and be enforceable by each of Parent’s successors and each Assignee and each of Purchaser’s successors and each Assignee, as applicable. Subject to compliance with the requirements set forth in this Section 6.3 relating to assignments, this Agreement shall not restrict Parent’s, Purchaser’s, any Assignee’s or any of their respective successors’ ability to merge or consolidate with, or sell, issue, license or dispose of its stock or other equity interests or assets to, any other Person, or spin-off or split-off. Each of Parent’s successors and Assignees, and each of Purchaser’s successors and Assignees, as applicable, shall expressly assume by an instrument supplemental

hereto, executed and delivered to the Rights Agent, the due and punctual payment of the CVRs and the due and punctual performance and observance of all of the covenants and obligations of this Agreement to be performed or observed by Parent or Purchaser, as applicable. The Rights Agent may not assign this Agreement without Parent’s written consent. Any attempted assignment of this Agreement or any such rights in violation of this Section 6.3 shall be void and of no effect.

Section 6.4 Benefits of Agreement. Nothing in this Agreement, express or implied, will give to any Person (other than the Rights Agent, Parent, Parent’s successors and Assignees, Purchaser, Purchaser’s successors and Assignees, the Holders and the Holders’ successors and assigns pursuant to a Permitted CVR Transfer) any benefit or any legal or equitable right, remedy or claim under this Agreement or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the foregoing. The rights of Holders and their successors and assigns pursuant to Permitted CVR Transfers are limited to those expressly provided in this Agreement. Notwithstanding anything to the contrary contained herein, any Holder or Holder’s successor or assign pursuant to a Permitted CVR Transfer may agree to renounce, in whole or in part, its rights under this Agreement by written notice to the Rights Agent and Parent, which notice, if given, shall be irrevocable. Except for the rights of the Rights Agent set forth herein, the Acting Holders will have the sole right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute any action or proceeding with respect to this Agreement, and no individual Holder or other group of Holders will be entitled to exercise such rights. Reasonable expenditures incurred by such Holders in connection with any enforcement action hereunder may be deducted from any damages or settlement obtained prior to the distribution of any remainder to Holders generally. Holders acting pursuant to this provision on behalf of all Holders shall have no liability to the other Holders for such actions.

Section 6.5 Governing Law; Jurisdiction; Waiver of Jury Trial.

Each of the parties irrevocably and unconditionally (1) agrees not to commence any such action or proceeding except in the Delaware Courts, (2) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (3) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (4) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts.

c) Parent, on behalf of itself and its Subsidiaries, hereby waives and agrees not to assert any defense that Parent does not have a Relevant Product for purposes of determining whether Parent has complied with Section 4.3(a).

d) EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE), INCLUDING ANY COUNTERCLAIM, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF.

Section 6.6 Severability.

Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable. The parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

Section 6.7 Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by an electronic scan delivered by electronic mail), each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other party, it being understood that the parties need not sign the same counterpart.

Section 6.8 Termination. This Agreement will be terminated and of no force or effect, the parties hereto will have no liability hereunder (other than with respect to monies due and owing by Parent or Purchaser to the Rights Agent), and no payments will be required to be made, upon the earliest to occur of (a) the mailing by the Rights Agent to the address of each Holder as reflected in the CVR Register the Milestone Payment Amount (if any) required to be paid under the terms of this Agreement, and (b) the delivery of a written notice of termination duly executed by Parent, Purchaser and the Acting Holders.

Section 6.10 Legal Holiday. In the event that the Milestone Payment Date shall not be a Business Day, then, notwithstanding any provision of this Agreement to the contrary, any payment required to be made in respect of the CVRs on such date need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Milestone Payment Date.
