2. CONTINGENT VALUE RIGHTS.

2.1 CVRs. The CVRs represent the rights of Holders to receive contingent cash payments pursuant to the Merger Agreement and this Agreement. The initial Holders will be the holders of Parent Common Stock as of immediately prior to the Effective Time.

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 Transfer.

2.3 No Certificate; Registration; Registration of Transfer; Change of Address; CVR Distribution.

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

(b) The Rights Agent will create and maintain a register (the “CVR Register”) for the purpose of registering CVRs and transfers of CVRs as herein provided. The CVR Register will be created, and CVRs will be distributed, pursuant to written instructions to the Rights Agent from Parent. The CVR Register will initially show one position for Cede & Co. representing all the shares of Parent Common Stock held by DTC on behalf of the street holders of the shares of Parent Common Stock 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. With respect to any payments to be made under Section 2.4(d) below, the Rights Agent will accomplish the payment to any former street name holders of shares of Company Common Stock 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.

(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, including a guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative or 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. Parent and Rights Agent may require payment of a sum sufficient to cover any stamp or other 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 applicable taxes or charges unless and until the Rights Agent is satisfied that all such taxes or charges have been paid. All duly transferred CVRs registered in the CVR Register will be the valid obligations of Parent 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.

(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, subject to its reasonable determination that the transfer instrument is in proper form, promptly record the change of address in the CVR Register.

(e) Parent will provide written instructions to the Rights Agent for the distribution of CVRs to holders of Parent Common Stock as of immediately prior to the Effective Time (the “Record Time”). Subject to the terms and conditions of this Agreement and Parent’s prompt confirmation of the Effective Time, the Rights Agent shall effect the distribution of the CVRs, less any applicable tax withholding, to each holder of Parent Common Stock as of the Record Time by the mailing of a statement of holding reflecting such CVRs.

2.4 CVR Payment and Related Procedures.

(a) Subsequent to any Gemcabene Deal, within sixty (60) days after the end of any CVR Payment Period during the CVR Term, Parent shall deliver to the Holders’ Representative and Rights Agent a CVR Payment Statement for such CVR Payment Period. Concurrent with the delivery of each CVR Payment Statement, Parent shall pay the Rights Agent in U.S. dollars an amount equal to the Net Proceeds (if any) received with respect to the applicable CVR Payment Period. For clarity, to the extent that any non-cash consideration in Gross Consideration is monetized after the end of the CVR Term, Parent will include a description of such non-cash consideration in the CVR Payment Statement for the CVR Payment Period in which it is received, and will make the applicable payment to the Rights Agent upon monetization of such non-cash consideration (regardless of whether such monetization occurs after the end of the CVR Term).

(b) Upon the Holders’ Representative’s request after receipt of any statement under Section 2.4(a), Parent shall promptly provide the Holders’ Representative with reasonable documentation to support its calculation of Net Proceeds (including any allocation applied when calculating the Gross Consideration component thereof and including its determination of the applicable fair market value(s)), and shall make its financial personnel reasonably available to the Holders’ Representative to discuss and answer the Holders’ Representative’s questions regarding such calculations. If the Holders’ Representative does not agree with Parent’s calculation, and the Holders’ Representative and Parent fail to agree on an alternative calculation within ten (10) Business Days after the Holders’ Representative requests documentation supporting Parent’s calculation, then the Parent and the Holders’ Representative shall engage a mutually agreeable independent third party valuation expert (a “Valuation Expert”) to determine the applicable calculation. The determination of the Valuation Expert will be final and binding on the Parent, the Rights Agent, the Holders’ Representative and each Holder, unless the Parent and Holders’ Representative agree otherwise in writing. The Valuation Expert shall be

an investment banker or other Person experienced in the valuation of pharmaceutical businesses and products, who shall not have had any material business relationship with Parent or the Holders’ Representative in the thirty-six (36) months prior to appointment, unless Parent and the Holders’ Representative agree in writing to waive this requirement. If the Holders’ Representative and Parent fail to agree on a Valuation Expert within thirty (30) days after determining to seek a Valuation Expert, the Holders’ Representative and Parent shall each designate a valuation expert, and the two such experts shall select a Valuation Expert. The Valuation Expert selected shall be entitled to apply discounted cash flow models and such other valuation models as she or he determines are appropriate under the circumstances, together with any other valuation models as may be agreed by the Holders’ Representative and Parent. Within ten (10) Business Days after the selection of the Valuation Expert, each of Parent and the Holders’ Representative will deliver to the Valuation Expert a detailed written proposal setting forth its proposed calculation of the Net Proceeds and Parent will deliver to the Valuation Expert a copy of the applicable Third Party agreements. Parent and the Holders’ Representative will use reasonable efforts to cause the Valuation Expert to make a determination within thirty (30) days after receipt of the proposals. Following its determination, the Valuation Expert shall deliver to Parent and the Holders’ Representative a report of her or his determination, and within thirty (30) days after receipt of such report, Parent shall make the applicable payment to the Rights Agent. The fees charged by the Valuation Expert shall be borne fifty percent (50%) by the Holders (through deduction from the next one or more CVR Payments, including the CVR Payment evaluated by the Valuation Expert) and fifty percent (50%) by Parent.

(c) All payments by Parent to the Rights Agent under this Agreement shall be made in U.S. dollars. The rate of exchange to be used in computing the amount of currency equivalent in U.S. dollars shall be made at the average of the closing exchange rates reported in The Wall Street Journal (U.S., Eastern Edition) for the ten (10) Business Days preceding the date of the CVR Payment Statement.

(d) The Rights Agent will promptly, and in any event within ten (10) Business Days after receipt of a CVR Payment Statement under Section 2.4(a), send each Holder at its address set forth on the CVR Register a copy of such statement. If the Rights Agent also receives any payment under Section 2.4(a) (each, a “CVR Payment”), then within ten (10) Business Days after the receipt of each CVR Payment, the Rights Agent will also pay to each Holder, 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 receipt of the CVR Payment Statement, such Holder’s Payment Amount.

(e) Parent shall be entitled to deduct or withhold, or cause the Rights Agent to deduct or withhold, from any amount otherwise payable to a Holder pursuant to Section 2.4(d) such amounts as may be required to be deducted or withheld therefrom under the Code, the Treasury Regulations thereunder, or any other applicable Tax Law, or as may be determined by Parent. Prior to making any such Tax withholdings or causing any such Tax withholdings to be made with respect to any Holder, Parent shall instruct the Rights Agent to solicit from such Holder an IRS Form W-9 or other applicable Tax form within a reasonable amount of time and such Holder shall promptly provide any necessary Tax forms (including an IRS Form W-9 or an applicable IRS Form W-8) in order to avoid or reduce such withholding amounts. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid, and prior to the 15th day of February in the year following any payment of such taxes by Parent or the Rights Agent, Parent shall deliver (or shall cause the Rights Agent to deliver) to the Person to whom such amounts would otherwise have been paid the original Form 1099 or other reasonably acceptable evidence of such withholding.

(f) Any portion of any CVR Payment that remains undistributed to the Holders six (6) months after the CVR Payment is received by the Rights Agent from the Parent, provided

that the Rights Agent has fully complied with Section 2.4(d), will be delivered by the Rights Agent to Parent, upon demand, and any Holder will thereafter look only to Parent for payment of its share of such returned CVR Payment, without interest, but such Holder will have no greater rights against Parent than those accorded to general unsecured creditors of Parent under applicable law.

(g) Neither Parent nor the Rights Agent will be liable to any person in respect of any Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If, despite Parent’s and/or the Rights Agent’s commercially reasonable efforts to deliver a Payment Amount to the applicable Holder, such Payment Amount has not been paid immediately prior to the date on which such Payment Amount would otherwise escheat to or become the property of any Governmental Entity, any such Payment Amount will, to the extent permitted by applicable law, become the property of Parent, 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, Parent 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 Parent.

(h) For the avoidance of doubt, as between Parent, Rights Agent and the Holders, Parent shall have sole responsibility for making all payments due pursuant to the Pfizer License Agreement. The CVR Payments shall be in addition to, and not in lieu of, any such payments.

2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent.

(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 or in any constituent company to the Merger.

(c) Each Holder acknowledges and agrees to the appointment and authority of the Holders’ Representative to act as the exclusive representative, agent and attorney-in-fact of such Holder and all Holders as set forth in this Agreement. Each Holder agrees that such Holder will not challenge or contest any action, inaction, determination or decision of the Holders’ Representative or the authority or power of the Holders’ Representative and will not threaten, bring, commence, institute, maintain, prosecute or voluntarily aid any action, which challenges the validity of or seeks to enjoin the operation of any provision of this Agreement, including, without limitation, the provisions related to the authority of the Holders’ Representative to act on behalf of such Holder and all Holders as set forth in this Agreement.

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 Parent without consideration therefor. Nothing in this Agreement is intended to prohibit Parent or its Affiliates from offering to acquire CVRs for consideration in its sole discretion.

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. Each notice will include the name and address of the successor Rights Agent. If Parent fails to send such notice within ten (10) Business Days after acceptance of appointment by a successor Rights Agent, the successor Rights Agent will cause the notice to be mailed at the expense of Parent.

3.4 Acceptance of Appointment by Successor. Every successor Rights Agent appointed hereunder will execute, acknowledge and deliver to Parent and to the retiring Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and thereupon such successor Rights Agent, without any further act, deed or conveyance, will become vested with all the rights, powers, trusts and duties of the retiring Rights Agent. On request of Parent or the successor Rights Agent, the retiring Rights Agent will execute and deliver an instrument transferring to the successor Rights Agent all the rights (except such rights of the predecessor Rights Agent which survive pursuant to Section 3.3 of this Agreement), powers and trusts of the retiring Rights Agent.

4. COVENANTS

4.1 List of Holders. Parent will furnish or cause to be furnished to the Rights Agent in such form as Parent receives from Parent’s transfer agent (or other agent performing similar services for Parent), the names and addresses of the Holders within ten (10) Business Days of the Effective Time.

4.2 Payment. If any CVR Payment is due under Section 2.4(a), Parent will deposit the CVR Payment with the Rights Agent for payment to the Holders in accordance with Section 2.4(d).

4.3 Development of Gemcabene Technology. Following the Effective Time, Parent shall make or Parent shall cause the Company to make an amount available, up to and not to exceed $1,000,000 (the “Gemcabene Funding”), to support the development of the Gemcabene Technology through the quarter ending March 31, 2020 (the “Covenant End Date”). The Gemcabene Funding will be allocated and spent based on the mutual agreement of Parent and the Holders’ Representative. Such amount shall be funded upon the execution by Parent of a license and collaboration agreement (the “Beijing SL Transaction”) with Beijing SL Pharmaceutical Co., Ltd. (“Beijing SL”), provided that such license and collaboration agreement with Beijing SL has been executed on terms acceptable to the Company prior to August 31, 2019, and the receipt by Parent of an upfront payment from Beijing SL in an amount not less than $2,500,000 to be paid by Beijing SL in accordance with the terms and conditions set forth in the license and collaboration agreement with Beijing SL. Following the Effective Time neither Parent nor the Company shall have any obligation to develop any Gemcabene Technology, or to expend any funds or efforts whatsoever with respect to the Gemcabene Technology, other than the provision of the Gemcabene Funding, which shall be used prior to the Covenant End Date to fund, to the extent such funds are sufficient therefor, (i) a toxicity study with respect to Gemcabene, (ii) a related submission to the Food and Drug Administration (the “FDA”) designed to result in the release of the partial clinical hold with respect to Gemcabene, (iii) preparation for an end-of-phase 2 meeting with the FDA, and (iv) consulting costs for up to four (4) former employees of Parent to support such activities. For the avoidance of doubt, following the Effective Time, neither the Company nor Parent has any obligation to provide further funding should the Gemcabene Funding not be sufficient to fund the matters set forth in (i) through (iv) in the previous sentence. Except as expressly set forth in this Section 4.3, Parent shall have no obligation to support the development of the Gemcabene Technology or to undertake any effort or expend any resource to divest or otherwise monetize the Gemcabene Technology or to maximize the likelihood or amount of any CVR Payment. Following the Covenant End Date, Parent may, at any time and in its sole and absolute discretion, discontinue any and all further efforts to develop, divest or otherwise monetize the Gemcabene Technology, upon a determination by the Board of Directors (as determined by a majority vote), it being understood and agreed that Parent has not promised or projected any CVR Payment and any such CVR Payment is speculative and may not occur.

4.4 Books and Records. Parent shall, and shall cause its Affiliates to, keep true, complete and accurate records in sufficient detail to enable the Holders and their consultants or professional advisors to confirm the applicable Payment Amount payable to each Holder hereunder in accordance with the terms specified in this Agreement.

4.5 Audits.

(a) Upon the written request of the Holders’ Representative provided to Parent not less than forty-five (45) days in advance (such request not to be made more than once in any twelve (12) month period), Parent shall permit, and shall cause its Affiliates to permit, the Independent Accountant to have access during normal business hours to such of the records of Parent or its Affiliates as may be reasonably necessary to determine the accuracy of the Net Proceeds reported by Parent. Parent shall, and shall cause its Affiliates to, furnish to the Independent Accountant such access, work papers and other documents and information reasonably necessary for the Independent Accountant to calculate and verify the Net Proceeds; provided that Parent may, and may cause its Affiliates to, redact documents and information not relevant for such calculation pursuant to this Section 4.5. The Independent Accountant shall disclose to Parent and the Holders’ Representative any matters directly related to its findings to the extent reasonably necessary to verify the Net Proceeds.

(b) If the Independent Accountant concludes that a CVR Payment that was properly due was not paid to the Rights Agent, or that any CVR Payment made was in an amount less than the amount due, Parent shall pay the CVR Payment or underpayment thereof to the Rights Agent for further distribution to the Holders (such amount being the “CVR Shortfall”). The CVR Shortfall shall be paid within ten (10) Business Days after the date the Independent Accountant delivers to Parent and the Holders’ Representative the Independent Accountant’s written report. The decision of the Independent Accountant shall be final, conclusive and binding on Parent and the Holders, shall be non-appealable and shall not be subject to further review. The fees charged by the Independent Accountant shall be paid by the Holders’ Representative; provided, however, that if the Independent Accountant concludes that Parent has underreported or underpaid any CVR Payment by more than twenty percent (20%), the fees charged by such Independent Accountant shall be paid by Parent.

(c) Each Person seeking to receive information from Parent in connection with a review pursuant to this Section 4.5 shall enter into, and shall cause its accounting firm to enter into, a reasonable and mutually satisfactory confidentiality agreement with Parent or any controlled Affiliate obligating such party to retain all such information disclosed to such party in confidence pursuant to such confidentiality agreement.

5. AMENDMENTS

(c) Promptly after the execution by Parent and the Rights Agent of any amendment pursuant to the provisions of this Section 5.1, Parent will mail (or cause the Rights Agent to mail) a notice thereof by first class mail to each Holder at its address as it appears on the CVR Register, setting forth such amendment. The failure to deliver such notice, or any defect in such notice, shall not impair or affect the validity of such amendment to this Agreement.

5.2 Amendments with Consent of Holders.

(a) Subject to Section 5.1 (which amendments pursuant to Section 5.1 may be made without the consent of the Holders), with the consent of the Acting Holders, whether evidenced in writing or taken at a meeting of the Holders, Holders’ Representative, Parent, when authorized by a Board Resolution, and the Rights Agent may enter into one or more amendments hereto for the purpose of adding, eliminating or changing any provisions of this Agreement, even if such addition, elimination or change is materially adverse to the interest of the Holders, including any amendment to effect any of the following:

(i) modify in a manner adverse to the Holders (A) any provision contained herein with respect to the termination of this Agreement or the CVRs, (B) the time for, and amount of, any payment to be made to the Holders pursuant to this Agreement, or (C) the definitions of Net Proceeds, including related definitions, such as Gross Consideration, Permitted Deductions, Gemcabene Deal, and Gemcabene Technology;

(ii) reduce the number of CVRs (except as provided in Section 5.1(b)(v)); or

(iii) modify any provisions of this Section 5.2, except to increase the percentage of Holders from whom consent is required or to provide that certain provisions of this Agreement cannot be modified or waived without the consent of the Holder of each outstanding CVR affected thereby.

(b) Promptly after the execution by Parent, the Holders’ Representative and the Rights Agent of any amendment pursuant to the provisions of this Section 5.2, Parent will mail (or

cause the Rights Agent to mail) a notice thereof by first class mail to each Holder at its address as it appears on the CVR Register, setting forth such amendment. The failure to deliver such notice, or any defect in such notice, shall not impair or affect the validity of such amendment to this Agreement.

5.3 Execution of Amendments. In executing any amendment permitted by this Section 5, the Rights Agent will be entitled to receive, and will be fully protected in relying upon, an opinion of counsel selected by Parent stating that the execution of such amendment is authorized or permitted by this Agreement. The Rights Agent may, but is not obligated to, enter into any such amendment that affects the Rights Agent’s own rights, privileges, covenants or duties under this Agreement or otherwise. No supplement or amendment to this Agreement shall be effective unless duly executed by the Rights Agent.

5.4 Effect of Amendments. Upon the execution of any amendment under this Section 5, this Agreement will be modified in accordance therewith, such amendment will form a part of this Agreement for all purposes and every Holder will be bound thereby.

6. HOLDERS’ REPRESENTATIVE

6.1 Appointment of Holders’ Representative. To the extent valid and binding under applicable law, the Holders’ Representative is hereby appointed, authorized and empowered to be the exclusive representative, agent and attorney-in-fact of each Holder, with full power of substitution, to make all decisions and determinations and to act (or not act) and execute, deliver and receive all agreements, documents, instruments and consents on behalf of and as agent for each Holder at any time in connection with, and that may be necessary or appropriate to accomplish the intent and implement the provisions of this Agreement and to facilitate the consummation of the transactions contemplated hereby, including without limitation for purposes of (i) negotiating and settling, on behalf of the Holders, any dispute that arises under this Agreement after the Effective Time, (ii) confirming the satisfaction of Parent’s obligations under this Agreement and (iii) negotiating and settling matters with respect to the amounts to be paid to the Holders pursuant to this Agreement.

6.2 Authority. To the extent valid and binding under applicable law, the appointment of the Holders’ Representative by the Holders upon the Effective Time is coupled with an interest and may not be revoked in whole or in part (including, without limitation, upon the death or incapacity of any stockholder). Subject to the prior qualifications, such appointment shall be binding upon the heirs, executors, administrators, estates, personal representatives, officers, directors, security holders, successors and assigns of each Holder. To the extent valid and binding under applicable law, all decisions of the Holders’ Representative shall be final and binding on all Holders. Parent and the Rights Agent shall be entitled to rely upon, without independent investigation, any act, notice, instruction or communication from the Holders’ Representative and any document executed by the Holders’ Representative on behalf of any Holder and shall be fully protected in connection with any action or inaction taken or omitted to be taken in reliance thereon, absent willful misconduct by Parent or the Rights Agent (as such willful misconduct is determined by a final, non-appealable judgment of a court of competent jurisdiction). The Holders’ Representative shall not be responsible for any loss suffered by, or liability of any kind to, the Holders arising out of any act done or omitted by the Holders’ Representative in connection with the acceptance or administration of the Holders’ Representative’s duties hereunder, unless such act or omission involves gross negligence or willful misconduct.

6.3 Successor Holders’ Representative. The Holders’ Representative may be removed for any reason or no reason by written consent of the Acting Holders. In the event that the Holders’ Representative becomes unable to perform its responsibilities hereunder or resigns or is removed from such position, the Acting Holders shall be authorized to and shall select another representative to fill

such vacancy and such substituted representative shall be deemed to be the Holders’ Representative for all purposes of this Agreement. The newly-appointed Holders’ Representative shall notify Parent, the Rights Agent and any other appropriate Person in writing of its appointment, provide evidence that the Acting Holders approved such appointment and provide appropriate contact information for purposes of this Agreement. Parent and the Rights Agent shall be entitled to rely upon, without independent investigation, the identity and validity of such newly-appointed Holders’ Representative as set forth in such written notice. In the event that within 30 days after the Holders’ Representative becomes unable to perform its responsibilities hereunder or resigns or is removed from such position, no successor Holders’ Representative has been so selected, Parent shall cause the Rights Agent to notify the Person holding the largest quantity of the outstanding CVRs (and who is not Parent or, to the Rights Agent’s actual knowledge, any Affiliate of Parent) that such Person is the successor Holders’ Representative, and such Person shall be the successor Holders’ Representative hereunder. If such Person notifies the Rights Agent in writing that such Person declines to serve, the Rights Agent shall forthwith notify the Person holding the next-largest quantity of the outstanding CVRs (and who is not Parent or, to the Rights Agent’s actual knowledge, any Affiliate of Parent) that such next-largest-quantity Person is the successor Holders’ Representative, and such next-largest-quantity Person shall be the successor Holders’ Representative hereunder. (And so on, to the extent as may be necessary.) The Holders are intended third party beneficiaries of this Section 6.3. If a successor Holders’ Representative is not appointed pursuant to the preceding procedure within 60 days after the Holders’ Representative becomes unable to perform its responsibilities hereunder or resigns or is removed from such position, Parent shall appoint a successor Holders’ Representative.

6.4 Termination of Duties and Obligations. The Holders’ Representative’s duties and obligations under this Agreement shall survive until no CVRs remain outstanding or until this Agreement expires or is terminated pursuant to Section 7.7(b), whichever is earlier.

7. OTHER PROVISIONS OF GENERAL APPLICATION

7.2 Notice to Holders. 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.

7.3 Parent Successors and Assigns; Merger of Rights Agent.

(a) Parent may not assign this Agreement without the prior written consent of the Holders’ Representative, provided that (a) Parent may assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more direct or indirect wholly-owned subsidiaries of Parent (each, an “Assignee”) provided that the Assignee agrees to assume and be bound by all of the terms of this Agreement; provided, however, that in connection with any assignment to an Assignee, Parent shall, and shall agree to, remain liable for the performance by such Assignee of all obligations of Parent hereunder, with such Assignee substituted for Parent under this Agreement, and (b) Parent may assign this Agreement in its entirety without the consent

of any other party to its successor in interest in connection with the sale of all or substantially all of its assets or of its stock, or in connection with a merger, acquisition or similar transaction (such successor in interest, the “Acquiror”, and such transaction, the “Acquisition”). This Agreement will be binding upon, inure to the benefit of and be enforceable by Parent’s successors, acquirers and each Assignee. Each reference to “Parent” in this Agreement shall be deemed to include Parent’s successors, acquirers and all Assignees. Each of Parent’s successors, acquirers and assigns shall expressly assume by an instrument supplemental hereto, executed and delivered to the Rights Agent, the due and punctual payment of the CVR Payments 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.

(b) Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the stock transfer or other shareholder services business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the Parties hereto, provided that such Person would be eligible for appointment as a successor Rights Agent under the provisions of the Agreement. The purchase of all or substantially all of the Rights Agent’s assets employed in the performance of transfer agent activities shall be deemed a merger or consolidation for purposes of this Section 7.3(b).

7.4 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, and the Holders) 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 Rights Agent, Parent, Parent’s successors and assignees, and the Holders. The rights of Holders are limited to those expressly provided in this Agreement and the Merger Agreement. Notwithstanding anything to the contrary contained herein, any Holder may agree to renounce, in whole or in part, such Holder’s rights under this Agreement by written notice to the Rights Agent and Parent, which notice, if given, shall be irrevocable. In such event, such Holder’s CVRs will not be included for determining the Payment Amounts to all other Holders. Further, for the avoidance of doubt, any decision by the Board of Directors to discontinue the pursuit of a Gemcabene Deal following the Covenant End Date shall be in the sole discretion of the Board of Directors, and shall not provide or give rise to a right of action to any Holder.

7.5 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. 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; provided, however, that if such excluded provision shall affect the rights, immunities, liabilities, duties or obligations of the Rights Agent, the Rights Agent shall be entitled to resign immediately upon written notice to the Parent.

7.6 Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by 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.

7.7 Termination.

(a) This Agreement will expire and be of no force or effect, the Parties hereto will have no liability hereunder (other than with respect to monies due and owing by Parent to Rights Agent or any other rights of the Rights Agent which expressly survive the termination of this Agreement), and no additional payments will be required to be made, upon the later of (i) the conclusion of the CVR Term and (ii) the payment of the full amount of all CVR Payments to the Rights Agent and the payment of the full amount of all Payment Amounts to the Holders by the mailing by the Rights Agent of each applicable Payment Amount to each Holder at the address reflected in the CVR Register.

(b) This Agreement will terminate automatically upon any termination of the Merger Agreement prior to the Effective Time.

7.8 Funds. All funds received by the Rights Agent under this Agreement that are to be distributed or applied by the Rights Agent in the performance of services hereunder (the “Funds”) shall be held by the Rights Agent as agent for the Parent and deposited in one or more bank accounts to be maintained by the Rights Agent in its name as agent for the Parent. Until paid pursuant to the terms of this Agreement, the Rights Agent will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Xxxxx’x (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). The Rights Agent shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by the Rights Agent in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other Third Party. The Rights Agent may from time to time receive interest, dividends or other earnings in connection with such deposits. The Rights Agent shall not be obligated to pay such interest, dividends or earnings to the Parent, any Holder or any other party.

7.9 Entire Agreement. Notwithstanding the reference to any other agreement hereunder, this Agreement contains the entire understanding of the Parties hereto and thereto with reference to the transactions and matters contemplated hereby and thereby and supersedes all prior agreements, written or oral, among the Parties with respect hereto and thereto. If and to the extent that any provision of this Agreement is inconsistent or conflicts with the Merger Agreement, this Agreement will govern and control.

7.10 Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between the Parties arising out of or relating to this Agreement, each Party: (a) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the United States District Court for the District of Delaware or, to the extent that neither of the foregoing courts has jurisdiction, the Superior Court of the State of Delaware; (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 7.10; (c) waives any objection to laying venue in any such action or proceeding in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party; (e) agrees that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 7.1 of this Agreement; and (f) irrevocably and unconditionally waives the right to trial by jury.
