CONTINGENT VALUE RIGHTS

Section 2.1 CVRs. CVRs shall be issued and distributed by Public Company in the form of a dividend, in connection with the Merger, to the Persons who, as of the close of business on the last Business Day prior to the day on which the Effective Time occurs, are a record holder of shares of Public Company Common Stock or shares of Public Company Preferred Stock entitled to receive such dividend in accordance with the terms of such Public Company Preferred Stock. Furthermore, to the extent a holder of a Public Company Warrant outstanding as of the date hereof exercises such Public Company Warrant after the date hereof (whether before or after the Closing), a number of CVRs equal to the number of shares of Public Company Common Stock issued to such holder in connection with such exercise shall be issued to such holder, subject to and in accordance with the terms and conditions of such Public Company Warrant, as applicable, and this Agreement. Notwithstanding anything to the contrary, this Agreement shall only become effective as of, and contingent upon, the Closing and shall be void ab initio and of no effect upon the valid termination of the Merger 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 Transfer. Any attempted sale, assignment, transfer, pledge, encumbrance or disposition of the CVRs, in whole or in part, that is not a Permitted Transfer, will be null and void ab initio and of no effect. CVRs will not be listed on any quotation system or traded on any securities exchange.

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

(a) The Holders’ rights and obligations in respect of CVRs derive solely from this Agreement; CVRs shall not be evidenced by a certificate or other instrument.

(b) Subject to the receipt by the Rights Agent of the information and instructions described in Section ‎4.1, the Rights Agent shall keep an up-to-date register (the “CVR Register”) for the purpose of: (i) identifying the Holders of CVRs and (ii) registering CVRs and Permitted Transfers thereof. The CVRs shall initially, in the case of the holders of shares of Public Company Common Stock and shares of Public Company Preferred Stock entitled to receive the dividend of CVRs in accordance with the terms of such Public Company Preferred Stock outstanding as of the as of the close of business on the last Business Day prior to the day on which the Effective Time occurs, be registered in the names and addresses of the respective holders as set forth in the form Public Company furnishes or causes to be furnished to the Rights Agent pursuant to Section 4.1. The CVR Register will initially show one position for Cede & Co. representing all of the shares of Public Company Common Stock held by DTC on behalf of the street holders of the shares of Public Company 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 Public 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. In addition, upon notification by the Public Company pursuant to Section 4.1, the Rights Agent shall reflect in the CVR Register the additional CVRs issued to the holders of Public Company Warrants who exercise such Public Company Warrants following the Closing.

(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 and other requested documentation in form reasonably satisfactory to the Rights Agent pursuant to its customary policies and guidelines, which may include 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, as applicable, and setting forth in reasonable detail the circumstances relating to the transfer. Upon receipt of such written notice, the Rights Agent shall, 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 such CVR in the CVR Register. Any transfer of CVRs will be without charge to the applicable Holder; provided, however, that Public Company, its Affiliates, and the 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 or 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 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 shall be the valid obligations of Public Company and shall 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 shall 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 shall promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures.

(a) Upon the occurrence of a CVR Event, as promptly as practicable (and in any event within forty-five (45) days after Public Company has received Net Proceeds from such CVR Event), Public Company shall (i) deliver (or cause to be delivered) to the Holder Representative and the Rights Agent an Officer’s Certificate (a “CVR Event Notice”): (A) certifying that a CVR Event has occurred and providing a reasonably detailed description of such CVR Event, including the date of the occurrence of such CVR Event, (B) certifying that each Holder is entitled to receive the CVR Payment Amount applicable to such Holder, and (C) setting forth Public Company’s calculation of the CVR Event Payment, and (ii) deliver (or cause to be delivered) to the Rights Agent any letter of instruction reasonably required by the Rights Agent.

(b) If (i) the Holder Representative does not object to any determination or calculation set forth in the CVR Event Notice by delivery of a written notice thereof to Public Company (with a copy to the Rights Agent) setting forth in reasonable detail such objection, together with reasonable supporting documentation (an “Objection Notice”) within thirty (30) calendar days following receipt of the applicable CVR Event Notice (the “Objection Period”), or (ii) the Holder Representative delivers a written notice to Public Company (with a copy to the Rights Agent) indicating that it has no objections to the calculations set forth in the CVR Event Notice, Public Company’s calculation of any CVR Event Payment, as applicable, shall be final and binding on all parties and the Holders. If the Holder Representative has not timely delivered an Objection Notice to Public Company during the Objection Period, the Holder Representative shall be deemed to have accepted the determination or calculation set forth in the CVR Event Notice.

(c) If the Holder Representative timely delivers to Public Company (with a copy to the Rights Agent) an Objection Notice, Public Company and the Holder Representative shall attempt in good faith to resolve such matters within thirty (30) calendar days after receipt of the same by Public Company, and if unable to do so, Public Company and the Holder Representative shall resolve any unresolved disputed in accordance with the provisions of Section 7, which decision will be final and binding on the parties.

(d) Within ten (10) Business Days of the final determination of a CVR Event Payment in accordance with the terms of this Agreement, Public Company shall deliver (or cause to be delivered) to the Rights Agent (i) any letter of instruction reasonably required by the Rights Agent, and (ii) cash, by wire transfer of immediately available funds to an account designated by the Rights Agent, in an amount equal to the applicable CVR Event Payment due to all Holders pursuant to Section 4.2, as finally determined pursuant to this Section 2.4. The Rights Agent will promptly, and in any event within ten (10) Business Days of receipt of such CVR Event Payment and any letter of instruction reasonably required by the Rights Agent, pay to each Holder in accordance with the corresponding letter of instruction, an amount equal to the product determined by multiplying (i) the quotient of: (A) the applicable CVR Event Payment divided by (B) the sum of: (x) the total number of CVRs registered in the CVR Register as of the date of such CVR Event, plus (y) the total number of CVRs that would be issued to the holders of Public Company Warrants outstanding as of the date of such CVR Event assuming the full exercise of such Public Company Warrants by the holders thereof (which number shall be determined by the Company and provided to the Rights Agent), by (ii) the number of CVRs registered to such Holder in the CVR Register at such time (each such amount, a “CVR Payment Amount”) (1) by check mailed to the address of such Holder, reflected in the CVR Register as of 5:00 p.m. New York City time on the last Business Day before such payment is made or (2) with respect to any such Holder who has provided the Rights Agent wiring instructions in writing as of the close of business on the last Business Day before such payment is made, by wire transfer of immediately available funds to the account specified on such instructions. Concurrently with the payment of the CVR Payment Amounts pursuant to the preceding sentence, Public Company shall deposit with the Rights Agent, for the benefit of holders of any Public Company Warrants that remain outstanding and unexercised, an amount equal to the aggregate CVR Payment Amounts that would be due with respect to the CVRs issuable to the holders of such Public Company Warrants if such Public Company Warrants had been exercised and the corresponding CVRs had been issued in respect of Public Company Common Stock issuable in connection with such exercise. The applicable portion of such CVR Payment Amounts deposited for the benefit of such holders of Public Company Warrants shall be (i) upon exercise of a Public Company Warrant and issuance of CVRs in respect of Public Company Common Stock issuable in connection with such exercise, paid out to the Holder of the CVRs so issued as a result of such exercise within ten (10) Business Days after such exercise, and (ii) upon expiration or termination of a Public Company Warrant, paid out as additional CVR Event Payments to the existing Holders within ten (10) Business Days after such expiration or termination.

(e) Each of Public Company, the Rights Agent and each of their respective Affiliates shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Agreement such amounts as it is required to deduct or withhold therefrom under applicable Law. Prior to making any such Tax withholdings or causing any such Tax withholdings to be made with respect to any Holder, the Rights Agent shall, to the extent practicable, provide notice to the Holder of such potential withholding and, if applicable, a reasonable opportunity for the Holder to provide any necessary Tax forms in order to avoid or reduce such withholding amounts; provided, that the time period for payment of a CVR Payment Amount by the Rights Agent to such Holder set forth in this Section 2.4 shall be extended by a period equal to any delay caused by such Holder in providing such forms. Any such amounts deducted or withheld and remitted to the appropriate Governmental Entity in accordance with applicable Law shall be treated for all purposes under this Agreement and the Merger Agreement as having been paid to the Holder to whom such amounts would otherwise have been paid.

(f) Any cash deposited with the Rights Agent pursuant to Section 2.4(d) (and any interest or other income earned thereon) that remains undistributed as of the date such CVR Payment Amount could properly be delivered to a public official pursuant to applicable abandoned, property, escheat, or similar applicable Law (including by means of invalid addresses on the CVR Register) shall be delivered by the Rights Agent to Public Company or its designated Affiliate, upon demand, and any Holder entitled to his, her or its CVR Payment Amount hereunder shall thereafter look to Public Company or any successor-in-interest of Public Company for payment of its claim for such CVR Payment Amount (subject to applicable abandoned property, escheat and other similar Law), without interest, but such Holder will have no greater rights against Public Company than those accorded to general unsecured creditors of Public Company under applicable Law. In addition to and not in limitation of any other indemnity obligation herein, Public Company agrees to indemnify and hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to Public Company.

(g) The right of the Holders to receive CVR Payment Amounts payable in respect of the CVRs hereunder shall rank equal in seniority with, or have priority over, the payment of any dividends on Public Company Common Stock whether in liquidation or otherwise.

(h) Except to the extent otherwise required pursuant to a change in applicable Law after the Closing Date, the Parties shall treat, for all Tax purposes, the issuance of the CVRs in accordance with the Agreed Tax Treatment as determined by Public Company, upon the advice and recommendation of its tax advisor PricewaterhouseCoopers LLP, after Public Company’s good faith consultation with its legal counsel and Merger Partner. The Agreed Tax Treatment shall be the treatment of the issuance of the CVRs, for Tax purposes, that is determined in accordance with the previous sentence, and shall be determined at least two (2) Business Days prior to the filing of the initial Registration Statement. The Parties will not take any position contrary to the Agreed Tax Treatment on any Tax Return or for other Tax purposes, except as required by a change in applicable Law after the Closing Date.

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in Public Company.

(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 Public Company, any constituent company to the transactions contemplated by the Merger Agreement, or any of their respective Subsidiaries or Affiliates. The rights of the Holders and the obligations of Public Company are contract rights limited to those expressly set forth in this Agreement, and such Holders’ sole right to receive property hereunder is the right to receive cash from Public Company, if any, through the Rights Agent in accordance with the terms hereof.

(c) It is hereby acknowledged and agreed that the CVRs and the possibility of any payment hereunder with respect thereto are highly speculative, and it is highly possible that Holders will not receive any payments under this Agreement or in connection with the CVRs. It is highly possible that no CVR Event will occur and accordingly it is highly possible that there will not be any CVR Payment. It is acknowledged and agreed that this Section 2.5(c) is an essential and material term of this Agreement.

Section 2.6 Ability to Abandon CVR. A Holder may, at any time and at such Holder’s option, abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Public Company without consideration therefor, which a Holder may affect by delivery of a written notice of such abandonment to Public Company and the Rights Agent, which abandonment notice, if given, shall be irrevocable. Nothing in this Agreement shall prohibit Public Company or any of its Affiliates 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 Public Company or any of its Affiliates shall be automatically deemed extinguished and no longer outstanding for purposes of the definition of Majority Holders, Section 2.4, Article V and Section 7.9. The Rights Agent shall update the CVR Register to reflect any abandonment or acquisition of CVRs described in this Section 2.6.

Section 2.7 Grant of Security. To secure all obligations owed to the Holders and the Holder Representative hereunder, including payment of the CVR Event Payments, Public Company hereby grants to the Holder Representative, for the benefit of the Holders, a first priority security interest in and continuing lien on all of the Public Company’s right, title and interest in, to and under the Strategic Partner Agreements, the TUM Agreement, and any payments to Public Company or any of its Affiliates associated therewith (net of any CVR Expenses incurred), including the right to receive any payments under such agreements, in each case whether now existing or hereafter acquired or arising, and any proceeds thereof

Without limiting the generality of the foregoing, (i) within ten (10) Business Days of Public Company or any of its Affiliates receiving any notices, records, files, documents, reports, correspondence, studies, or other information (collectively, “Strategic Partner Information”) from a Strategic Partner or any of such Strategic Partner’s Affiliates related to a Strategic Partner Agreement or Strategic Partner Payment, Public Company shall (or shall cause its Affiliates to) deliver such Strategic Partner Information to the Holder Representative, and (ii) promptly (an in any event within ten (10) Business Days) upon becoming aware of any material development under any Strategic Partner Agreement, Public Company or one of its Affiliates shall deliver to the Holder Representative notice of such material development.

Public Company 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 confirm compliance with this Agreement, including the calculation of any Net Proceeds; provided that Public Company may, and may cause its Affiliates to, redact documents and information not relevant for such purposes. The Independent Accountant shall disclose to Public Company and the Holder Representative any matters directly related to its findings to the extent reasonably necessary to verify compliance with the terms of this Agreement. Notwithstanding anything to the contrary, including Section 2.4, if the Independent Accountant concludes that a CVR Event Payment that was properly due was not paid to the Rights Agent, or that any CVR Event Payment made was in an amount less than the amount due, Public Company shall pay the CVR Event Payment or underpayment thereof to the Rights Agent for further distribution to the Holders (such amount being the “CVR Event Payment Shortfall”). The CVR Event Payment Shortfall shall be paid within ten (10) Business Days after the date the Independent Accountant delivers to Public Company and the Holder Representative the Independent Accountant’s written report. The decision of the Independent Accountant shall be final, conclusive and binding on Public Company 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 Holder Representative (on behalf of the Holders from the Holder Representative Expense Fund, to the extent such funds are available). Each Person seeking to receive information from Public Company or any of its Affiliates in connection with a review pursuant to this Section 4.3 shall enter into a reasonable and mutually satisfactory confidentiality agreement with Public Company or any controlled Affiliate obligating such party to retain all such information disclosed to such party in confidence pursuant to such confidentiality agreement.

ARTICLE VI

THE HOLDER REPRESENTATIVE

Section 6.1 Appointment. Effective upon the Closing and the issuance of the CVRs under this terms of this Agreement, and without any further act of any of Holders, the Holder Representative is appointed as the representative of the Holders and as the attorney-in-fact and agent for and on behalf of each Holder for purposes of this Agreement and will take such actions to be taken by the Holder Representative under this Agreement and such other actions on behalf of such Holders as it may deem necessary or appropriate in connection with or to consummate the transactions contemplated hereby, including (i) executing and delivering this Agreement and any other ancillary documents and negotiating and executing any amendments, modifications, waivers or changes thereto as to which the Holder Representative, in its sole discretion, has consented (provided that any waiver or amendment that adversely and disproportionately affects the rights or obligations of one or more Holders as compared to other Holders will require the prior written consent of a majority in interest of the disproportionately affected Holders), (ii) agreeing to, negotiating, entering into settlements and compromises of, complying with orders of courts with respect to, and otherwise administering and handling any claims under this Agreement on behalf of such Holders, and (iii) taking all other actions that are either necessary or appropriate in the judgment of the Holder Representative for the accomplishment of the foregoing or contemplated by the terms of this Agreement. The Holder Representative hereby accepts such appointment as of the Closing. The appointment of the Holder Representative as each Holder’s attorney-in-fact revokes any power of attorney heretofore granted that authorized any other Person to represent such Holder with regard to this Agreement and any other agreements or documents executed or delivered in connection with this Agreement. The Holder Representative is the sole and exclusive representative of each of the Holders for any purpose provided for by this Agreement.

Section 6.2 Actions of Holder Representative.

(a) A decision, act, consent or instruction of the Holder Representative hereunder will constitute a decision, act, consent or instruction of all Holders and will be final, binding and conclusive upon each such Holder, and Public Company and the Rights Agent may rely upon any such decision, act, consent or instruction of the Holder Representative as being the decision, act, consent or instruction of each and every such Holder. Public Company and the Rights Agent will be relieved from any liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of the Holder Representative.

(b) The Holder Representative will incur no liability in connection with its services pursuant to this Agreement and any related agreements except to the extent resulting from its gross negligence, bad faith or willful misconduct. The Holder Representative shall not be liable for any action or omission pursuant to the advice of counsel.

(c) Public Company will indemnify the Holder Representative against any reasonable, documented, and out-of-pocket losses, liabilities and expenses (“Representative Losses”) arising out of or in connection with this Agreement and any related agreements, in each case as such Representative Loss is suffered or incurred; provided, that in the event that any such Representative Loss is finally adjudicated to have been caused by the gross negligence, bad faith or willful misconduct of the Holder Representative, the Holder Representative will reimburse Public Company the amount of such indemnified Representative Loss to the extent attributable to such gross negligence, bad faith or willful misconduct. Representative Losses shall be recovered by the Holder Representative from (i) the funds in the Expense Fund and (ii) any CVR Event Payments owed, or that may become due and owing, to the Holders hereunder; provided, that while the Holder Representative may be paid from the aforementioned sources of funds, this does not relieve Public Company from its obligation to promptly pay such Representative Losses as they are suffered or incurred. In no event will the Holder Representative be required to advance its own funds on behalf of Public Company, the Holders or otherwise. Notwithstanding anything in this Agreement to the contrary, any restrictions or limitations on liability or indemnification obligations of, or provisions limiting the recourse against non-parties otherwise applicable to, the Holders or Public Company set forth elsewhere in this Agreement are not intended to be applicable to the indemnities provided to the Holder Representative hereunder. The foregoing indemnities will survive the Closing, the resignation or removal of the Holder Representative or the termination of this Agreement.

(d) At the Effective Time, Public Company will wire US$250,000 (the “Holder Representative Expense Fund”) to the Holder Representative, which will be used for any expenses incurred by the Holder Representative. Neither Public Company nor the Holders will receive any interest or earnings on the Holder Representative Expense Fund and irrevocably transfer and assign to the Holder Representative any ownership right that they may otherwise have had in any such interest or earnings. The Holder Representative will hold these funds separate from its corporate funds and will not voluntarily make these funds available to its creditors in the event of bankruptcy. As soon as practicable following the completion of the Holder Representative’s responsibilities hereunder, the Holder Representative will deliver any remaining balance of the Holder Representative Expense Fund to the Rights Agent (for pro rata distribution to the Holders). For tax purposes, the Holder Representative Expense Fund will be treated as having been received and voluntarily set aside by the Holders at the time of Closing.

(e) Public Company shall deliver a copy of any and all notices, written instruments and any other information delivered to the Rights Agent hereunder to the Holder Representative concurrently with such delivery to the Rights Agent.

(b) At any time the Majority Holders may remove the Holder Representative by specifying a date when such removal shall take effect, but no such removal shall become effective until a successor Holder Representative has been appointed. Notice of such removal shall be given by the Majority Holders to Public Company and the Rights Agent, which notice shall be sent at least thirty (30) calendar days prior to the date so specified.

(c) If the Holder Representative provides notice of its intent to resign pursuant to Section 6.3(a), is removed pursuant to Section 6.3(b) or becomes incapable of acting, the Majority Holders shall, as soon as is reasonably possible, appoint a qualified successor Holder Representative. Notwithstanding the foregoing, if the Majority Holders fail to make such appointment within a period of thirty (30) calendar days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Holder Representative, then the Majority Holders may apply to any court of competent jurisdiction for the appointment of a new Holder Representative. The successor Holder Representative so appointed shall, forthwith upon its acceptance of such appointment in accordance with Section 6.3, become the successor Holder Representative.

(d) The Majority Holders shall give notice of each resignation and each removal of a Holder Representative and each appointment of a successor Holder Representative by mailing written notice of such event by first-class mail to Public company, the Rights Agent and to the Holders as their names and addresses appear in the CVR Register. Each notice shall include the name and address of the successor Holder Representative. If the Majority Holders fail to send such notice within thirty (30) calendar days after acceptance of appointment by a successor Holder Representative, the successor Holder Representative shall cause the notice to be mailed.

(e) The Rights Agent and Public Company will reasonably cooperate with any successor Holder Representative in connection with the transition of the duties and responsibilities of the Holder Representative to the successor Holder Representative but the Rights Agent shall not be required to make any additional expenditure or assume any additional liability in connection with the foregoing.

Section 6.4 Grant of Authority. The grant of authority provided for in this Article VI is coupled with an interest and will be irrevocable and survive the death, incompetency, bankruptcy or liquidation of any Holder. The provisions of this Article VI will be binding upon the executors, heirs, legal representatives, successors and assigns of each Holder, and any references in this Agreement to any Holder or the Holders will mean and include the successors to such Holder’s rights hereunder, whether pursuant to testamentary disposition, the Laws of descent and distribution or otherwise.

ARTICLE VII

Section 7.3 Notice to Holders. Where this Agreement provides for notice to Holders, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and transmitted through the facilities of DTC in accordance with DTC’s procedures or 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 shall affect the sufficiency of such notice with respect to other Holders.

Section 7.4 Governing Law. 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 thereof.

Section 7.5 Specific Enforcement; Jurisdiction.

(a) Public Company and Holder Representative acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that Public Company and Holder Representative shall be entitled to an injunction or injunctions, or any other appropriate form of equitable relief, to prevent breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement in any court referred to in Section 7.5(b), without proof of damages or otherwise (and each party hereto hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at Law or in equity. Public Company and Holder Representative further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy. Public Company and Holder Representative acknowledge and agree that the right of specific enforcement is an integral part of this Agreement and without such right, none of the parties hereto would have entered into this Agreement.

(b) Each of the parties hereto hereby irrevocably submits to the exclusive jurisdiction of the courts of the State of Delaware and to the jurisdiction of the United States District Court for the State of Delaware, for the purpose of any Proceeding arising out of or relating to this Agreement or the actions of the parties hereto in the negotiation, administration, performance and enforcement thereof, and each of the parties hereto hereby irrevocably agrees that all claims with respect to such Proceeding may be heard and determined exclusively in the Delaware Court of Chancery or, solely if the Delaware Court of Chancery does not have subject matter jurisdiction thereof, any other court of the State of Delaware or any federal court sitting in the State of Delaware. Each of the parties hereto (i) consents to submit itself to the personal jurisdiction of the Delaware Court of Chancery, any other court of the State of Delaware and any federal court sitting in the State of Delaware in the event any Proceeding arises out of this Agreement, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iii) irrevocably consents to the service of process in any Proceeding arising out of or relating to this Agreement, on behalf of itself or its property, by U.S. registered mail to such party’s respective address set forth in Section 7.2 (provided that nothing in this Section 7.5(b) shall affect the right of any party hereto to serve legal process in any other manner permitted by Law) and (iv) agrees that it will not bring any Proceeding relating to this Agreement in any court other than the Delaware Court of Chancery (or, solely if the Delaware Court of Chancery shall be unavailable, any other court of the State of Delaware or any federal court sitting in the State of Delaware). The parties hereto agree that a final trial court judgment in any such Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law; provided that nothing in the foregoing shall restrict any party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

Section 7.6 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING ARISING OUT OF THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 7.6.

Section 7.7 Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.

Section 7.8 Entire Agreement; Counterparts. As between the Public Company and Holder Representative, this Agreement, the Merger Agreement and the other agreements, exhibits, annexes and schedules referred to herein constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, between such parties, with respect to the subject matter hereof and thereof. As among the Public Company, Holder Representative, and the Rights Agent, this Agreement and any schedule or exhibit attached hereto contains the entire understanding of such parties with reference to the transactions and matters contemplated hereby 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 with respect to the rights, duties, protections and liabilities of the Rights Agent, this Agreement will govern and be controlling. This Agreement and any signed agreement or instrument entered into in connection with this Agreement may be executed in two or more counterparts (including by facsimile or 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 parties, it being understood that all parties need not sign the same counterpart. To the extent signed and delivered by means of a facsimile machine or telecopy, by email delivery of a “.pdf” or “.jpg” format data file or by any electronic signature complying with the U.S. federal ESIGN Act of 2000, this Agreement shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or telecopy, email delivery of a “.pdf” or “.jpg” format data file or electronic signature complying with the U.S. federal ESIGN Act of 2000 to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or telecopy, email delivery of a “.pdf” or “.jpg” format data file or by any electronic signature complying with the U.S. federal ESIGN Act of 2000 as a defense to the formation of a contract and each party hereto forever waives any such defense.

Section 7.9 Third-Party Beneficiaries; Action by the Holder Representative. Public Company, the Holder Representative, and the Rights Agent hereby agree that the respective covenants and agreements set forth herein are intended to be for the benefit of all Holders, who are intended third-party beneficiaries hereof, and shall be enforceable by the Holder Representative on their behalf. Public Company, the Holder Representative, and the Rights Agent further agree that this Agreement and their respective covenants and agreements set forth herein are solely for the benefit of Public Company, the Rights Agent, the Holder Representative, and the Holders and their respective permitted successors and assigns hereunder in accordance with and subject to the terms of this Agreement, and nothing in this Agreement, express or implied, will confer upon any Person other than Public Company, the Rights Agent, the Holder Representative, the Holders and their respective permitted successors and assigns hereunder any benefit or any legal or equitable right, remedy or claim hereunder. The rights of Holders and their successors and assigns pursuant to Permitted Transfers are limited to those expressly provided in this Agreement and the Merger Agreement. Notwithstanding anything to the contrary contained herein, any Holder or Holder’s successor or assign pursuant to a Permitted Transfer may agree to renounce, in whole or in part, its rights under this Agreement by written notice to the Holder Representative, Rights Agent and Public Company, which notice, if given, shall be irrevocable. The Holder Representative will have the right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute a Proceeding with respect to this Agreement and no individual Holder or other group of Holders, nor the Rights Agent on behalf thereof, will be entitled to exercise such rights. In the event of an insolvency proceeding of Public Company or any of its Affiliates, individual Holders shall be entitled to assert claims in such insolvency proceeding and take related actions in pursuit of such claims with respect to any payment that may be claimed by or on behalf of Public Company or by any creditor of Public Company, as applicable. Except for the right of the Rights Agent set forth in this Agreement or as set forth in the preceding sentence, the Holder Representative 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 at Law or in equity or in bankruptcy or otherwise upon or under or with respect to this Agreement, and no individual Holder or other group of Holders will be entitled to exercise such rights. Notwithstanding any other provision in this Agreement, the right of any Holder to receive payment of the applicable CVR Payment Amounts upon the occurrence of a CVR Event shall not be impaired or adversely affected without the consent of such Holder.

Section 7.10 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the Parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision. Notwithstanding anything to the contrary herein, if an 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 Public Company.

Section 7.11 Assignment. This Agreement shall not be assignable without the prior written consent of each of the other Parties to this Agreement; provided, however, (a) Public Company may assign any or all of its rights, interests and obligations under this Agreement to a Person that is a controlled Affiliate of Public Company without the consent of any other party; provided that Public Company remains jointly and severally liable for all of the obligations of Public Company under this Agreement, (b) Public Company may assign any or all of its rights, interests and obligations under this Agreement in connection with a sale of all or substantially all of the assets of Public Company; provided that the successor in any such sale transaction expressly assumes all of the obligations of Public Company under this Agreement, (c) Public Company may assign any or all of its rights, interests and obligations under this Agreement to any Person with the prior written consent of the Holder Representative, and (d) the Rights Agent may, without the consent of any other party, assign this Agreement to a successor Rights Agent appointed in compliance with Section 3.4. The Rights Agent, Public Company and the Holder Representative agree that all books, records, information and data pertaining to the business of the other party, including inter alia, personal, non-public Holder information, which are exchanged or received pursuant to the negotiation or the carrying out of this Agreement including the fees for services set forth in the attached schedule shall remain confidential, and shall not be voluntarily disclosed to any other person, except as may be required by law, including, without limitation, pursuant to subpoenas from state or federal government authorities (e.g., in divorce and criminal actions).

Section 7.12 Confidentiality. The Rights Agent, Public Company and the Holder Representative agree that all books, records, information and data pertaining to the business of the other parties, including inter alia, personal, non-public Holder information, and the fees for the services of the Rights Agent and the Holder Representative, which are exchanged or received pursuant to the negotiation or the carrying out of this Agreement shall be confidential and shall not be used for any purpose other than carrying out their respective duties under this Agreement and shall not be voluntarily disclosed to any other Person, including any Holder, except as may be required by a valid order of any Governmental Entity of competent jurisdiction or is otherwise required by applicable Law, the rules and regulations of the Securities and Exchange Commission or any stock exchange on which the securities of the disclosing party are listed, or pursuant to subpoenas from state or federal Governmental Entities (subject to (x) the disclosing party notifying, to the extent practicable, the other parties hereto of such potential disclosure reasonably in advance of such disclosure, or (y) cooperating with the other parties, at the expense of the other parties, in any effort to restrict disclosure of such book, records, information). Notwithstanding anything herein or in Section 7.11 to the contrary, following Closing, the Holder Representative shall be permitted to disclose information to advisors and representatives of the Holder Representative and to the Holders, in each case who have a need to know such information, provided that such persons are subject to confidentiality obligations with respect thereto.

Section 7.13 No Obligation. Except as expressly set forth in this Agreement, in no event shall Public Company or any of its Affiliates be required to undertake any level of efforts, or employ any level of resources, to ensure that a CVR Event Payment occurs; provided, that none of Public Company, its Affiliates or any of their respective successors and assigns shall take any action or fail to take any action in bad faith for the purpose of avoiding the occurrence of any CVR Event or the payment of (or minimizing or reducing the amount of) any CVR Event Payment.

Section 7.14 Force Majeure. Notwithstanding anything to the contrary contained herein, no party hereto will have any liability for not performing, or a delay in the performance of, any act, duty, obligation or responsibility by reason of any occurrence beyond the reasonable control of such party (including any act or provision or any present or future law or regulation or governmental authority, any act of God, epidemics, pandemics, war, civil or military disobedience or disorder, riot, rebellion, terrorism, insurrection, fire, earthquake, storm, flood, strike, work stoppage, interruptions or malfunctions of computer facilities, loss of data due to power failures or mechanical difficulties, labor dispute, accident or failure or malfunction of any utilities communication or computer services or similar occurrence).
