CONTINGENT VALUE RIGHTS

Section 2.1Holders of CVRs; Appointment of Rights Agent.

(a)The CVRs represent the rights of Holders to receive CVR Payments pursuant to the Exchange Agreement and this Agreement. The initial Holders will be the holders of Common Stock as of 5:00 p.m. ET on the Record Date (the “Record Time”). One CVR will be issued with respect to each share of Common Stock that is outstanding as of the Record Time.

(b)The Company 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 the Company and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the transactions contemplated hereby. This Agreement has been duly executed and delivered by Company and, assuming the due authorization, execution and delivery by the Rights Agent, constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. Neither the execution and delivery of this Agreement nor the performance by the Company 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 the Company, 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 the Company 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 the Company. No consent, approval, order or authorization of, or registration, declaration, notice or filing with, any Governmental Body is required by or with respect to the Company in connection with the execution and delivery of this Agreement by the Company or the consummation by the Company of the transactions contemplated hereby, except such consents, approvals, orders, authorizations, registrations, declarations, notices and filings as may be required under applicable federal, state and provincial securities Laws.

(c)The Company hereby appoints the Rights Agent to act as Rights Agent for the Company in accordance with the express terms and conditions set forth in this Agreement, and the Rights Agent hereby accepts such appointment.

Section 2.2Non-transferable. 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 any CVR, in whole or in part, in violation of this Section 2.2 shall be null and void ab initio and of no effect. The CVRs will not be listed on any quotation system or traded on any securities exchange.

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

(a)The CVRs will be issued in book-entry form only and will not be evidenced by a certificate or other instrument.

(b)The Rights Agent shall create and maintain a register (the “CVR Register”) for the purpose of (i) identifying the Holders of the CVRs and (ii) registering the CVRs and Permitted Transfers. The CVR Register will be created, and CVRs will be distributed, pursuant to written instructions to the Rights Agent from the Company. The CVR Register will initially show one position for Cede & Co. representing shares of Common Stock held by DTC on behalf of the street holders of the shares of Common Stock held by such holders as of the Record Time. The Rights Agent will have no responsibility whatsoever directly or indirectly to the street name holders with respect to transfers of CVRs. With respect to any payments or issuances to be made under Section 2.4 below, the Rights Agent will accomplish the payment to any former street name holders of shares of Common Stock by sending one lump-sum payment or issuance to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments or shares of Common Stock by DTC to such street name holders.

(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 or procedures, including a guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative duly authorized in writing or 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 otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the applicable CVRs in the CVR Register. The Company and Rights Agent may require evidence of payment of a sum sufficient to cover any stamp, documentary, registration, or other Tax or governmental charge that is imposed in connection with any such registration of transfer (or evidence that such Taxes and charges are not applicable). 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 the Company and will entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR will be valid until registered in the CVR Register.

(d)A Holder (or an authorized representative thereof) 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 shall, subject to its reasonable determination that the transfer instrument is in proper form, promptly record the change of address in the CVR Register. The Acting Holders may, without duplication, make a written request to the Company for a list containing the names, addresses and number of CVRs of the Holders that are registered in the CVR Register. Upon receipt of such written request from the Acting Holders, the Company will cause the Rights Agent to promptly deliver a copy of such list to the Acting Holders.

(e)The Company will provide written instructions to the Rights Agent for the distribution of CVRs to holders of Common Stock as of the Record Time. Subject to the terms and conditions of this Agreement, the Rights Agent shall effect the distribution of the CVRs, less any applicable Tax withholding, to each holder of Common Stock as of the Record Time by the mailing of a statement of holding reflecting such CVRs.

Section 2.4Payment Procedures.

(a)No later than sixty (60) days following the end of each Calendar Quarter during the CVR Term beginning with the Calendar Quarter ending on December 31, 2024, commencing with the first CVR Payment Period in which the Company or its Affiliates receives an Upfront Payment or a Milestone Payment, the Company shall deliver to the Rights Agent a CVR Payment Statement for such CVR Payment Period. Concurrent with the delivery of each CVR Payment Statement, on the terms and conditions of this Agreement, the Company shall pay the Rights Agent in U.S. dollars an amount equal to the CVR Payment for the applicable CVR Payment Period. Such CVR Payment will be transferred by wire transfer of immediately available funds to an account designated in writing by the Rights Agent not less than twenty (20) Business Days prior to the date of the applicable payment (the Company acknowledges that additional wire transfer fees may apply). Upon receipt of the wire transfer referred to in the foregoing sentence, the Rights Agent shall promptly (and in any event, within ten (10) Business Days) pay to each Holder set forth in the CVR Register at such time, an amount equal to such Holder’s CVR Payment Amount. The Rights Agent shall promptly, and in any event within ten (10) Business Days after receipt of a CVR Payment Statement under this Section 2.4(a), send each Holder at its registered address a copy of such statement (at the Company’s sole cost and expense). For the avoidance of doubt the Company shall have no further liability in respect of the relevant CVR Payment upon delivery of such CVR Payment in accordance with this Section 2.4(a) and the satisfaction of each of the Company’s obligations set forth in this Section 2.4(a).

(b)With respect to cash deposited by the Company with the bank or financial institution designated by Rights Agent (currently Wells Fargo or U.S. Bank), Rights Agent agrees to cause such bank or financial institution to establish and maintain a separate demand deposit account, therefor in the name of Rights Agent for the benefit of the Company. 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. Rights Agent shall have no responsibility or liability for any diminution of funds that may result from any deposit or investment made by 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 Rights Agent. Rights Agent may from time to time receive interest in connection with such deposits. Rights Agent shall not be obligated to pay such interest to the Company, any Holder or any other party. Rights Agent is acting as an agent hereunder and is not a debtor of the Company in respect of cash deposited hereunder. For the avoidance of doubt, the Company acknowledges 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 Body as a bank or a trust company.

(c)The Rights Agent shall solicit from each Holder an IRS Form W-9 or applicable IRS Form W-8 at such time or times as is necessary to permit any payment under this Agreement to be made without U.S. federal backup withholding. That notwithstanding, the Company shall be entitled to deduct and withhold, and hereby authorizes the Rights Agent to deduct and withhold, any Tax that is required to be deducted or withheld under applicable law from any amounts payable pursuant to this Agreement. To the extent the amounts are so withheld by the Company or the Rights Agent, as the case

may be, and paid over to the appropriate Governmental Body, such withheld 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.

(d)Any portion of a CVR Payment that remains undistributed to the Holders six (6) months after the applicable Calendar Quarter end (including by means of uncashed checks or invalid addresses on the CVR Register) will be delivered by the Rights Agent to the Company or a person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent), and any Holder will thereafter look only to the Company for payment of such CVR Payment (which shall be without interest).

(e)If any CVR Payment (or portion thereof) remains unclaimed by a Holder two (2) years after the applicable Calendar Quarter end (or immediately prior to such earlier date on which such CVR Payment would otherwise escheat to or become the property of any Governmental Body), such CVR Payment (or portion thereof) will, to the extent permitted by applicable Law, become the property of the Company and will be transferred to the Company or a person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent), free and clear of all claims or interest of any Person previously entitled thereto, and no consideration or compensation shall be payable therefor. Neither the Company nor the Rights Agent will be liable to any Person in respect of a CVR Payment delivered to a public official pursuant to any applicable abandoned property, escheat or similar legal requirement under applicable Law.

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

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

(b)The CVRs will not represent any equity or ownership interest in the Company. It is hereby acknowledged and agreed that a CVR shall not constitute a security of the Company.

(c)Nothing contained in this Agreement shall be construed as conferring upon any Holder, by virtue of the CVRs, any rights or obligations of any kind or nature whatsoever as a stockholder or member of the Company or any of its subsidiaries either at law or in equity. The rights of any Holder and the obligations of the Company and its Affiliates and their respective officers, directors and controlling Persons are contract rights limited to those expressly set forth in this Agreement.

(d)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 the Company’s control, and there is no assurance that Holders will receive any payments under this Agreement or in connection with the CVRs. Each Holder acknowledges that it is highly possible that no Upfront Payment or Milestone Payment will occur and that there will not be any CVR Payment Amount. It is further acknowledged and agreed that neither the Company nor its Affiliates owe, by virtue of their obligations under this Agreement, a fiduciary duty or any implied duties to the Holders and the parties hereto, and the Company and its Affiliates intend solely the express provisions of this Agreement to govern their contractual relationship with respect to the CVRs. It is acknowledged and agreed that this Section 2.5(d) is an essential and material term of this Agreement.

Section 2.6Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights represented by CVRs by transferring such CVRs to the Company or a Person nominated in writing by the Company (with written notice thereof from the Company to the Rights Agent) without consideration in compensation therefor, and such rights will be

cancelled, with the Rights Agent being promptly notified in writing by the Holder of such transfer and cancellation. Nothing in this Agreement is intended to prohibit the Company or its Affiliates from offering to acquire or acquiring CVRs, in private transactions or otherwise, for consideration in its sole discretion.

(d)The Rights Agent may engage and consult with counsel of its selection, and the advice or opinion of such counsel will, in the absence of bad faith, fraud, gross negligence or willful misconduct (in each case, as determined by a final, non-appealable judgment of a court of competent jurisdiction) on the part of the Rights Agent, be full and complete authorization and protection in respect of any action taken or not taken by the Rights Agent in reliance thereon.

(h)The Rights Agent will have no liability and shall be held harmless by the Company 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 the Company), nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement.

(i)The Rights Agent shall not be obligated to take any legal or other action hereunder which might, in its judgment, subject or expose it to any expense or liability unless it shall have been furnished with an indemnity satisfactory to it.

(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 any of its rights or powers if it believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(o)The Rights Agent shall not be subject to, nor be required to comply with, or determine if any Person has complied with, the Exchange Agreement or any other agreement between or among any of the Company, Target or Holders, even though reference thereto may be made in this Agreement, or to comply with any notice, instruction, direction, request or other communication, paper or document other than as expressly set forth in this Agreement.

(p)In the event the Rights Agent reasonably believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Rights Agent hereunder, the Rights Agent shall, as soon as practicable, provide notice to the Company, and the Rights Agent may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to the Company or any Holder or any other Person for refraining from taking such action, unless the Rights Agent receives written instructions from the Company or such Holder or other Person which eliminate such ambiguity or uncertainty to the reasonable satisfaction of the Rights Agent;

(q)The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company or Target resulting from any such act, default, neglect or misconduct, absent gross negligence, bad faith or willful misconduct (each as determined by a final non-appealable judgment of a court of competent jurisdiction) in the selection and continued employment thereof.

that is not a stock transfer agent of national reputation or the corporate trust department of a commercial bank.

Rights Agent shall be entitled to reimbursement by the Company for costs and expenses related to such transition services.

Section 3.4Acceptance of Appointment by Successor. Every successor Rights Agent appointed hereunder will, at or prior to such appointment, execute, acknowledge and deliver to the Company and to the resigning or removed Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and such successor Rights Agent, without any further act, deed or conveyance, will become vested with all the rights, powers, trusts and duties of the Rights Agent; provided that upon the request of the Company or the successor Rights Agent, such resigning or removed Rights Agent will execute and deliver an instrument transferring to such successor Rights Agent all the rights, powers and trusts of such resigning or removed Rights Agent.

No accounting period of the Company shall be subject to audit more than one time by the Acting Holders, unless after an accounting period has been audited by the Acting Holders, the Company restates its financial results for such accounting period, in which event the Acting Holders may conduct a second audit of such accounting period in accordance with this Section 4.7. Adjustments (including remittances of underpayments or overpayments disclosed by such audit) shall be made by the Parties to reflect the results of such audit, which adjustments shall be paid promptly following receipt of an invoice therefor. The Acting Holders shall bear the full cost and expense of such audit unless such audit discloses an underpayment by the Company of twenty percent (20%) or more of the CVR Payments due under this Agreement for the audited period, in which case the Company shall bear the full cost and expense of such audit.

Section 7.10Severability Clause. 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 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 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.
