The CVRs represent the contractual rights of Holders to receive contingent cash payment of the aggregate CVR Proceeds from Purchaser pursuant to this Agreement. Parent has all requisite corporate power and authority to execute and deliver this Agreement and to perform its obligations hereunder and to consummate the transactions contemplated by this Agreement. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Parent and no other corporate proceedings on the part of Parent are necessary to authorize this Agreement or to consummate the transactions contemplated hereby. This Agreement has been duly executed and delivered by Parent and, assuming the due authorization, execution and delivery by the Rights Agent, Purchaser and the Representative, constitutes a legal, valid and binding obligation of Parent, enforceable against Parent in accordance with its terms. Neither the execution and delivery of this Agreement nor the performance by Parent of its obligations hereunder or the consummation of the transactions contemplated hereby will (i) conflict with, or result in any violation of any provision of the certificate of incorporation, bylaws and other similar organizational documents of Parent, or (ii) conflict with, or result in any violation of or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation under, any loan or credit agreement, note, mortgage, indenture, lease, or other agreement, obligation, instrument, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Parent or its properties or assets which violation, in the case of clause (ii), individually or in the aggregate, would reasonably be expected to be material to Parent. No consent, approval, order or authorization of, or registration, declaration, notice or filing with, any Governmental Body is required by or with respect to Parent in connection with the execution and delivery of this Agreement by Parent or the consummation by Parent of the transactions contemplated hereby. Parent hereby appoints Broadridge Corporate Issuer Solutions, LLC as the Rights Agent to act as rights agent for Parent in accordance with the instructions hereinafter set forth in this Agreement, and Broadridge Corporate Issuer Solutions, LLC hereby accepts such appointment.

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 be issued and distributed by Purchaser to each Holder in book-entry form only and 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 Company Common Stock held by DTC on behalf of the street holders of the 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 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 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. Upon request of a Holder or the Representative to Parent, Parent will cause the Rights Agent to make available to such Holder or the Representative, as applicable, a list of the other Holders, the number of CVRs held by each Holder, the contact information, including email address, maintained by the Rights Agent with respect to each Holder and such other information relating to this Agreement as may be reasonably requested by the Representative and is information that is typically stored by a rights agent in accordance with general industry practices for similar types of engagements.

(c) Subject to the restrictions on transferability set forth in Section 2.2 and subject to the Rights Agent’s bona fide procedures to validate the identity of a Holder, 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 and proper validation of the identity of such Holder, 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 the Rights Agent may require a transferring Holder or its transferee to pay to the applicable Governmental Body any transfer, stamp, documentary, registration, 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 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 and proper validation of the identity of such Holder, the Rights Agent will promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures: Notices.

(a) If a Disposition Agreement is entered into during the Disposition Period, then Parent shall promptly deliver to the Rights Agent (with a copy to the Representative) written notice indicating that a Disposition Agreement has been entered into and a copy of the Disposition Agreement and any ancillary agreements thereto.

(b) On or prior to each CVR Payment Date, with respect to any Disposition Agreement or Permitted Disposition, Parent shall deliver to the Rights Agent (with a copy to the Representative) (i) written notice indicating that (A) the Holders are entitled to receive one or more payments with respect to Disposition Proceeds, (B) in the case of Disposition Proceeds, the source and trigger event for such payment of Disposition Proceeds, (C) a detailed calculation of Gross Proceeds (including any calculations or supporting documentation applicable to any allocation determination for consideration related or not related to a CVR Product), Net Proceeds and any Permitted Deductions used to calculate such Disposition Proceeds with reasonable supporting detail for such Permitted Deductions, as applicable, (each such notice, a “CVR Payment Notice”), (ii) a letter of instruction setting forth, for each CVR, the CVR Payment Amount with respect thereto (including each component included in the calculation thereof) and (iii) any other letter of instruction reasonably required by the Rights Agent. On or prior to any CVR Payment Date, Parent shall deliver to the Rights Agent the CVR Payment Amounts required by Section 4.2. All amounts delivered by Parent hereunder shall be delivered in U.S. dollars. For the avoidance of doubt, Parent shall have no further liability in respect of the relevant CVR Payment Amount upon delivery of such CVR Payment Amount in accordance with this Section 2.4(b) and the satisfaction of each of Parent’s obligations set forth in this Section 2.4(b) and Section 2.5. With respect to cash deposited by Parent or Purchaser with the bank or financial institution designated by the Rights Agent (which shall be Wells Fargo, U.S. Bank or another bank or financial institution of substantially equivalent national reputation and financial standing), the Rights Agent agrees to cause such bank or financial institution to establish and maintain a separate demand deposit account, therefor in the name of the Rights Agent for the benefit of Parent. The Rights Agent will only draw upon cash in such account(s) as required from time to time in order to make payments as required under this Agreement and any applicable tax withholding payments. The Rights Agent shall have no responsibility or liability for any diminution of funds that may result from any deposit or investment 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, in the absence of fraud, bad faith or willful

misconduct by or on behalf of the Rights Agent. 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 Parent, Purchaser, the Representative, any Holder or any other party. The Rights Agent is acting as an agent hereunder and is not a debtor of Parent in respect of cash deposited hereunder. For the avoidance of doubt, Parent, Representative and Purchaser acknowledge that (i) the Rights Agent is not a bank or a trust company, (ii) the Rights Agent is not acting in any sort of capacity as an “escrow” or similar agent hereunder, and (iii) nothing in this Agreement shall be construed as requiring the Rights Agent to perform any services that would require registration with any governmental authority as a bank or a trust company.

(c) The Rights Agent will promptly, and in any event within ten (10) Business Days after receipt of the CVR Payment 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 CVR Payment Notice (at Parent’s sole cost and expense) and, following the applicable CVR Payment Date, promptly pay the CVR 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 CVR Payment Date.

(d) Any portion of the CVR Payment Amount that remains undistributed to a Holder six (6) months after the date of the delivery of the applicable CVR Payment Date 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 CVR 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 CVR Payment Amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If, despite Parent’s, any of its Affiliates’ or the Rights Agent’s commercially reasonable efforts to deliver the CVR Payment Amount to the applicable Holder, the CVR Payment Amount has not been paid prior to two (2) years after the applicable CVR Payment Date (or immediately prior to such earlier date on which the CVR Payment Amount would otherwise escheat to or become the property of any Governmental Body), the CVR Payment Amount will, to the extent permitted by applicable Law, become the property of Parent or 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, Parent and Purchaser agree 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 Parent or Purchaser.

Section 2.5 Tax Matters.

(a) Except to the extent any portion of the CVR Payment Amount is required to be treated as imputed interest pursuant to applicable Law, Parent, Purchaser and the Representative intend that, for all U.S. federal and applicable state and local income tax purposes, (i) the CVRs received in respect of Company Common Stock (which for avoidance of doubt does not include the Equity Award CVRs) will be treated as additional consideration paid with respect

to such Company Common Stock in connection with the Offer or the Merger, as the case may be, (ii) any CVR Payment Amount received in respect of such CVRs will be treated as an amount realized on the disposition or partial disposition of the applicable CVRs, and (iii) any CVR Payment Amount paid in respect of any Equity Award CVR will be treated as compensation in the year in which the CVR Payment Amount is made (and not upon the receipt of such CVR). Parent and Purchaser shall file all U.S. federal, state and local Tax Returns in a manner consistent with clauses (i) and (ii), unless otherwise required by applicable Laws and clause (iii), unless otherwise required by a “determination” within the meaning of Section 1313(a) of the Code (or a similar determination under applicable state or local Law).

(b) In addition to any Permitted Deductions, Parent and its Affiliates (including Purchaser) and the Rights Agent shall be entitled to deduct and withhold, or cause to be deducted or withheld, from each CVR 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 payroll system or any successor payroll system of Parent or any of its Affiliates, including the Company. 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 Holders to provide duly executed Internal Revenue Service Forms W-9 or W-8, as applicable, or any other reasonably appropriate forms or information from Holders in order to eliminate or reduce withholding. 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.

(c) Parent, Purchaser and the Representative intend that each payment provided under this Agreement with respect to an Equity Award CVR (the “Payments”) is a separate “payment” for purposes Section 1.409A-2(b)(2)(i) of the U.S. Treasury Regulations. For the avoidance of doubt, Parent, Purchaser and the Representative intend that the Payments satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code and the Treasury Regulations and other guidance issued thereunder and any state law of similar effect (collectively “Section 409A”) provided under Treasury Regulations Section 1.409A-1(b)(4) and, to the extent not so exempt, that the Payments comply, and this Agreement be interpreted to the greatest extent possible, as consistent with Treasury Regulations Section 1.409A-3(i)(5)(iv)(A)—that is, as “transaction-based compensation.” To the extent this Agreement (and any definitions hereunder), or any payments hereunder, are not exempt, they shall be construed in a manner that complies with Section 409A, including by reason of satisfying the “transaction-based compensation” provisions thereunder, including the five-year post-Closing payment limitation therein, and shall incorporate by reference all required definitions and payment terms. Notwithstanding the foregoing, none of Parent, the Company or the Board, or any of their respective representatives make any representation or warranty and will have no liability to a Holder or transferee or any other Person if any payments under any provisions of this Agreement are determined to constitute deferred compensation under Section 409A of the Code (or any similar U.S. state tax law) that are subject to certain additional federal, state or other taxes. Parent may provide each recipient of an Equity Award CVR with a notice or award agreement setting forth the terms and condition of the Holder’s entitlement to payments under such Equity Award CVR in accordance with the terms of this Agreement. The Rights Agent makes no representations or warranties with respect to tax treatment of the CVRs. None of the Rights Agent, its Affiliates or the services provided by the Rights Agent hereunder are intended to provide legal, tax or financial advice.

Section 2.6 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 or any of their respective Affiliates. It is hereby acknowledged and agreed that a CVR shall not constitute a security of Parent.

(c) Each Holder, by virtue of the approval of the Merger and this Agreement by the Initial Holders or the receipt of any consideration in connection with the Merger, and without any further action of any of the Holders or the Company, acknowledges and agrees to the appointment and authority of the Representative, as of the Offer Closing Time, to act as the exclusive representative, agent and true and lawful attorney-in-fact of such Holder and all Holders as set forth in this Agreement, which shall include the power and authority of the Representative to (i) incur and pay expenses on behalf of the Holders as required hereunder, (ii) exercise the audit rights under Section 4.4, and (iii) take or refrain from taking the actions specified herein and any other actions relating to the subject matter of this Agreement reasonably deemed necessary or appropriate by the Representative. Notwithstanding the foregoing, the Representative shall have no obligation to act on behalf of the Holders, except as expressly provided herein and in the Representative Engagement Agreement, and for the avoidance of doubt, the Representative shall have no obligations of the Representative under the Merger Agreement or any ancillary agreement, schedule or exhibit thereto other than this Agreement. All actions taken by the Representative in accordance with the terms of this Agreement and the Representative Engagement Agreement shall be binding upon each Holder and such Holder’s successors as if expressly confirmed and ratified in writing by such Holder, and all defenses which may be available to any Holder to contest, negate or disaffirm any such action of the Representative taken in good faith under this Agreement or the Representative Engagement Agreement are waived. Each Holder agrees that such Holder 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 the provisions relating to the authority of the Representative to act on behalf of such Holder and all Holders as set forth in this Agreement. The Representative shall be entitled to: (A) rely upon the CVR Register and associated list of Holders, (B) rely upon any signature reasonably believed by it to be genuine, and (C) reasonably assume that a signatory has proper authorization to sign on behalf of the applicable Holder or other party.

(d) Parent, its Board and its officers and Affiliates will not be deemed to have any fiduciary or similar duties to any Holder by virtue of this Agreement.

(e) It is hereby acknowledged and agreed that the CVRs and the possibility of any payment hereunder with respect thereto are highly speculative and subject to numerous factors outside of Parent’s control, and there is no assurance that Holders will receive any payments under this Agreement or in connection with the CVRs. The Parties acknowledge that it is possible that no Disposition will occur during the Disposition Period and that there will not be any Gross Proceeds that may be the subject of a CVR Payment Amount.

Section 2.7 Ability to Renounce or Abandon CVR. Notwithstanding anything to the contrary contained herein, any Holder or Holder’s successor or assign pursuant to a Permitted CVR Transfer may, at any time, at such Holder’s option, agree to renounce, in whole or in part, its rights under this Agreement and abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Purchaser or Parent without consideration therefor, effected by written notice to the Rights Agent, the Representative and Parent, which renouncement and abandonment notice, if given, shall be irrevocable. 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 VI and Section 6.3 hereunder.

ARTICLE III

(h) the Rights Agent will have no liability and shall be held harmless by Parent in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution and delivery hereof by the Rights Agent and the enforceability of this Agreement against the Rights Agent assuming the due execution and delivery hereof by Parent), nor shall it be responsible for any breach by Parent of any covenant or condition contained in this Agreement;

(i) the Rights Agent shall not be required to perform any action if such action would cause the Rights Agent to violate any applicable law, regulation or court order;

(j) the Rights Agent shall not be deemed to have any knowledge of any event of which it was to receive notice thereof hereunder, and the Rights Agent shall be fully protected and shall incur no liability for failing to take any action in connection therewith, unless and until it has received such notice in writing;

(k) the Rights Agent shall not assume any obligations or relationship of agency or trust with the Representative or any Holder;

(l) Parent agrees to indemnify the Rights Agent and its affiliates, and its and their respective employees, officers, directors, representatives and advisors for, and hold such Persons harmless against, any loss, liability, damage, judgment, fine, penalty, cost or expense (each, a “Loss”) arising out of or in connection with the Rights Agent’s duties under this Agreement, including the reasonable, documented and necessary out-of-pocket costs and expenses of defending the Rights Agent against any claims, charges, demands, actions or suits arising out of or in connection with the execution, acceptance, administration, exercise and performance of its duties under this Agreement or enforcing its rights hereunder, unless such Loss has been determined by a court of competent jurisdiction to be a result of Rights Agent’s gross negligence, bad faith, fraud or willful misconduct; provided that this Section 3.2(h) shall not apply with respect to income, receipt, franchise or similar Taxes;

(m) Parent agrees (i) to pay the fees and expenses of the Rights Agent in connection with this Agreement as agreed upon in writing by the Rights Agent and Parent on or prior to the date hereof and (ii) to reimburse the Rights Agent for all reasonable, documented and necessary out-of-pocket expenses paid or incurred by the Rights Agent in connection with the administration by the Rights Agent of its duties hereunder, including all stamp and transfer Taxes (and excluding for the avoidance of doubt any income, receipt, franchise or similar) and governmental charges, except that Parent will have no obligation to pay the fees of the Rights Agent or reimburse the Rights Agent for the fees of counsel in connection with any lawsuit initiated by the Rights Agent on behalf of itself, except in the case of any suit enforcing the provisions of Section 2.4(a), Section 2.4(b), Section 2.4(c), Section 2.4(d) or Section 3.2, if Parent is found by a court of competent jurisdiction to be liable to the Rights Agent or the Holders, as applicable in such suit; and

(n) 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.

Section 3.3 Resignation and Removal; Appointment of Successor.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent (with a copy to the Representative) 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. The Representative shall have the right to remove the 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 the Representative to Rights Agent (with a copy to Parent), 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 and the Representative, acting in concert, 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.

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 in accordance with Section 3.4, the successor Rights Agent will cause the notice to be mailed at the expense of Parent.

Section 3.4 Transition Support. As long as all fees and charges that are due and payable to the Rights Agent for the Rights Agent’s services performed under this Agreement have been paid, the Rights Agent will cooperate with Parent, the Representative and any successor Rights Agent as reasonably requested in connection with the transition of the duties and responsibilities of the Rights Agent to the successor Rights Agent, including the transfer of all relevant data, including transferring the CVR Register to the successor Rights Agent.

Parent will furnish or cause to be furnished to the Rights Agent (with a copy to the Representative) in such form as Parent receives from the Company’s transfer agent (or other agent performing similar services for Parent), the names, email addresses and addresses of the Holders of such securities within thirty (30) days of the Closing Date.

Notwithstanding anything herein to the contrary, but subject to Parent’s obligations as set forth herein, (a) Parent and its Affiliates shall have the power and right to control all aspects of their businesses and operations (and all of their assets and products), and subject to its compliance with the terms of this Agreement, Parent and its Affiliates may exercise or refrain from exercising such power and right as it may deem appropriate and in the best overall interests of Parent and its Affiliates and its and

their stockholders, rather than the interest of the Holders, and (b) following the Disposition Period, the Company shall be permitted to take any action in respect of the CVR Products; provided that, during the Disposition period:

(a) Neither Parent nor any of its Affiliates (including Purchaser) may enter into a Disposition Agreement with Parent or any of its Affiliates (including Purchaser) as the acquiror, licensee or recipient of any CVR Products without the prior written consent of the Representative.

Section 4.4 Audit Right. Parent agrees to maintain, for at least six months after the applicable CVR Payment Date, all books and records relevant to the calculation of a CVR Payment Amount and the amount of Gross Proceeds, Net Proceeds and Permitted Deductions. Subject to reasonable advance written notice from the Representative and prior execution and delivery by it and an independent accounting firm of national reputation chosen by the Representative (the “Accountant”) of a reasonable and customary confidentiality/nonuse agreement, Parent shall permit the Representative and the Accountant, acting as agent of the Representative (on behalf of the Holders), to have access during normal business hours to the books and records of Parent as may be reasonably necessary to audit the calculation of such CVR Payment Amount, the calculation of the amount of Gross Proceeds, Net Proceeds and Permitted Deductions.

Section 4.5 Assignments. Parent shall not, in whole or in part, assign any of its obligations under this Agreement other than in accordance with the terms of Section 6.3. At any time, the Representative may resign (in which case the Acting Holders shall promptly appoint a successor Representative (reasonably acceptable to Parent)) and may assign any of its rights or obligations under this Agreement (or this Agreement in its entirety) to any third party (reasonably acceptable to Parent) to serve as a successor Representative, provided that such assignee executes a written joinder to this Agreement assuming the rights and duties of the Representative.

Section 4.6 Additional Covenants.

(a) During the Disposition Period, Purchaser shall, and shall cause its Subsidiaries, licensees and rights transferees to, use commercially reasonable efforts to enter into one or more Disposition Agreements as promptly as practicable following the Effective Time.

(b) In the event that Purchaser desires to consummate a Change of Control prior to the Expiration Date, Purchaser or its successor, as applicable depending upon the structure of the Change of Control, will cause the Person acquiring Purchaser to assume Purchaser’s or its successor’s (as applicable depending upon the structure of the Change of Control) obligations, duties and covenants under this Agreement. No later than five (5) Business Days after to the consummation of any Change of Control, Purchaser will deliver to the Rights Agent an Officer’s Certificate, stating that such Change of Control complies with this Section 4.6(b) and that all conditions precedent herein relating to such transaction have been complied with.

(d) Upon the reasonable written request from the Representative, and subject to the Representative executing a customary confidentiality agreement in the event the information provided would constitute material non-public information of Parent, Parent will provide (i) during the Disposition Period the Representative with a written update in reasonable detail describing the progress, status and anticipated trajectory of efforts in respect of Dispositions and (ii) the anticipated timing of receiving payments in respect of such Dispositions, in each case up to one time in a fiscal quarter of each calendar year.

(e) Parent shall, and shall cause its Affiliates, including the Company, to, until such time as this Agreement is terminated pursuant to Section 6.8, (i) comply in all material respects with their respective covenants and obligations (A) under each Disposition Agreement and (B) approved by Parent in accordance with Section 7.16 of the Merger Agreement and governing a Permitted Disposition, and (ii) consider the interests of the Holders under this Agreement in good faith, and not take any action, or fail to take any action, the primary purpose of which is to circumvent the purpose of this Agreement and the intent of the parties, including by reducing the amount of Disposition Proceeds.

(f) Parent shall cause the Company to pay the Disposition Management Bonus Payments with respect to the Net Proceeds underlying any Disposition Proceeds in a special payroll cycle on the applicable CVR Payment Date.

(g) Certain Holders have entered into an engagement agreement (the “Representative Engagement Agreement”) with the Representative and agreed to provide direction to the Representative in connection with its services under this Agreement and the Representative Engagement Agreement (such Holders, including their individual representatives, collectively hereinafter referred to as the “Advisory Group”). Neither the Representative nor its members, managers, directors, officers, contractors, agents and employees nor any member of the Advisory Group (collectively, the “Representative Group”), shall be liable to any Holder for any action or failure to act in connection with the acceptance or administration of the Representative’s responsibilities hereunder or under the Representative Engagement Agreement, unless and only to the extent such action or failure to act constitutes gross negligence, fraud or willful misconduct. The Holders shall indemnify, defend and hold harmless the Representative Group from and against any and all losses, claims, damages, liabilities, fees, costs, expenses (including fees, disbursements and costs of counsel and other skilled professionals and in connection with seeking recovery from

insurers), judgments, fines, amounts paid in settlement (collectively, the “Representative Expenses”) incurred without gross negligence, fraud or willful misconduct on the part of the Representative and arising out of or in connection with the acceptance or administration of its duties hereunder or its duties (or any duties of any member of the Advisory Group) under the Representative Engagement Agreement. Such Representative Expenses may be recovered first, from the Expense Fund, second, from any distribution of CVR Payment Amounts otherwise distributable to the Holders at the time of distribution, and third, directly from the Holders. The immunities and rights to indemnification shall survive the resignation or removal of the Representative or any member of the Advisory Group or any termination of this Agreement. The Holders acknowledge that the Representative shall not be required to expend or risk its own funds or otherwise incur any financial liability in the exercise or performance of any of its powers, rights, duties or privileges or pursuant to this Agreement, the Representative Engagement Agreement or the transactions contemplated hereby or thereby. Furthermore, the Representative shall not be required to take any action unless the Representative has been provided with funds, security or indemnities which, in its reasonable determination, are sufficient to protect the Representative against the costs, expenses and liabilities which may be incurred by the Representative in performing such actions. The powers, immunities and rights to indemnification granted to the Representative Group hereunder: (i) are coupled with an interest and shall be irrevocable and survive the death, incompetence, bankruptcy or liquidation of any Holder and shall be binding on any successor thereto, and (ii) shall survive the delivery of an assignment by any Holder of the whole or any fraction of his, her or its interest in the CVR Proceeds. At the Offer Closing Time, the Company shall wire to the Representative $120,000 (the “Expense Fund Amount”). The Expense Fund Amount shall be held by the Representative in a segregated client account and shall be used (A) for the purposes of paying directly or reimbursing the Representative for any Representative Expenses incurred pursuant to this Agreement or the Representative Engagement Agreement, or (B) as otherwise determined by the Advisory Group (the “Expense Fund”). The Representative is not providing any investment supervision, recommendations or advice and shall have no responsibility or liability for any loss of principal of the Expense Fund other than as a result of its gross negligence, fraud or willful misconduct. The Representative is not acting as a withholding agent or in any similar capacity in connection with the Expense Fund and has no tax reporting or income distribution obligations. The Holders will not receive any interest on the Expense Fund and assign to the Representative any such interest. Subject to Advisory Group approval, the Representative may instruct the Rights Agent to contribute funds to the Expense Fund from the CVR Payment Amounts otherwise distributable to any Holders, on a pro rata basis. As soon as reasonably determined by the Representative that the Expense Fund is no longer required to be withheld, the Representative shall distribute the remaining Expense Fund, if any, to the Rights Agent for further distribution to the Holders in such proportions as though the amount of the remaining Expense Fund constituted CVR Proceeds hereunder (provided that, any amounts remaining from the amounts contributed to the Expense Fund from the CVR Payment Amounts otherwise distributable to any Holders pursuant to the previous sentence shall first be distributed to such Holders in proportion to such Holders’ respective contributions).

In connection with any assignment to an Assignee described in clause (i) above in this Section 6.3 and clause (ii) 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 or dispose of its stock or other equity interests or assets to, any other Person. 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 (with a copy to the Representative), the due and punctual payment of the aggregate CVR Proceeds 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 the Representative’s written consent, except to an affiliate of the Rights Agent in connection with a corporate restructuring or to a successor Rights Agent in accordance with the terms of this Agreement. 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, the Representative, 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 herein, the Representative shall not commence any action under this Agreement on behalf of or to enforce the rights of the Holders except at the direction of and with the prior written consent of the Acting Holders. Except for the rights of the Rights Agent and the Representative 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. The Representative and all Holders (including the Acting Holders) must enforce any such legal or equitable rights, remedies or claims under this Agreement against Parent and Purchaser and not against the Rights Agent.

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

(a) This Agreement, the CVRs and all actions arising under or in connection therewith 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 law thereof.

(b) Each of the parties hereto (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Chancery Court of the State of Delaware and any state appellate court therefrom or, if (but only if) such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware and any appellate court therefrom (collectively, the “Delaware Courts”); and (ii) consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such party is to receive notice in accordance with Section 6.1. Each of the parties irrevocably and unconditionally (A) agrees not to commence any such action or proceeding except in the Delaware Courts, (B) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (C) 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 (D) 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) 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. EACH PARTY HERETO (A) MAKES THIS WAIVER VOLUNTARILY AND (B) ACKNOWLEDGES THAT SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS CONTAINED IN THIS SECTION 6.5(C).

Section 6.6 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.

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 or the Representative), 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 of all CVR Payment Amounts (if any) required to be paid under the terms of this Agreement, (b) the delivery of a written notice of termination duly executed by Parent, Purchaser and the Acting Holders, or (c) subject to Section 4.4, the Expiration Date (only to the extent that a Disposition does not occur prior to the Expiration Date). For the avoidance of doubt and notwithstanding anything to the contrary, nothing herein shall terminate or otherwise negatively affect any of the rights or remedies of the Representative Group with respect to the Holders pursuant to this Agreement or otherwise.

Section 6.9 Entire Agreement. This Agreement, the Merger Agreement (including the schedules, annexes and exhibits thereto and the documents and instruments referred to therein) contain the entire understanding of the parties hereto and thereto with reference to the transactions and matters contemplated hereby and thereby and supersede all prior agreements, written or oral, among the parties with respect hereto and thereto.

Section 6.10 Legal Holiday. In the event that the CVR 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 CVR Payment Date.

Section 6.11 Obligations of Parent. Parent shall ensure that Purchaser, and Purchaser shall ensure that Parent, duly perform, satisfy and discharge each of the covenants, obligations and liabilities applicable to such party under this Agreement, and Parent shall be jointly and severally liable with Purchaser for the performance and satisfaction of each of said covenants, obligations and liabilities.
