2.1. CVRs. As provided in the Merger Agreement, effective as of the Effective Time, (i) each Share shall be converted into the right to receive the Merger Consideration, which includes one CVR, and (ii) each Company Warrant that is assumed and converted pursuant to Section 5.3(c) of the Merger Agreement shall be treated in accordance with its terms. The initial Holders shall be determined pursuant to the terms of the Merger Agreement and this Agreement, and a list of the initial Holders shall be furnished to the Rights Agent by or on behalf of Parent in accordance with Section 4.1 hereof.

2.2. Non-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, and, in the case of a Permitted Transfer, only in accordance with Section 2.3(c) hereof and in compliance with applicable United States federal and state securities laws and the terms and conditions hereto. Any such sale, assignment, transfer, pledge, encumbrance or disposal of CVRs, in whole or in part, in violation of this Section 2.2, shall be null and void and of no effect.

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

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

(b) The Rights Agent shall keep a register (the “CVR Register”) for the purpose of identifying the Holders and registering CVRs and transfers of CVRs as herein provided. The CVR Register will initially show one position for Cede & Co. representing all of the CVRs that are issued to the holders of Shares held by DTC on behalf of the street holders of the Shares. The Rights Agent will have no responsibility whatsoever directly to the street name holders or DTC participants with respect to transfers of CVRs. With respect to any payments to be made under Section 2.4 below, the Rights Agent will accomplish such payment to any former street name holders of the Shares by sending such payments to DTC. The Rights Agent will have no responsibilities whatsoever with regard to the distribution of payments by DTC to such street name holders.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer in form reasonably satisfactory to the Rights Agent pursuant to its written guidelines, 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 the CVRs in the CVR Register and notify Parent of the same. Any registration, transfer or assignment of the CVRs shall

be without charge to the Holder (other than payment of a sum to the extent necessary to cover any stamp or other Tax or other governmental charge that is imposed in connection with any such registration, transfer or assignment). All duly transferred CVRs registered in the CVR Register shall be the valid obligations of Parent 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 unless and until registered in the CVR Register.

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

2.4. Payment Procedures.

(a) If any Milestone is achieved, then, in each case, on a date (a “Milestone Payment Date”) that is within 60 days following the last day of such Calendar Quarter in which such Milestone is achieved:

(i) Parent will deliver to the Rights Agent (A) a notice (a “Milestone Notice”) indicating the achievement of such Milestone and that the Holders are entitled to receive the applicable Milestone Amount and (B) cash in the aggregate amount of the Milestone Amount.

(b) The Rights Agent shall promptly, and in any event within 10 Business Days of receipt of a Milestone Notice, as well as any letter of instruction reasonably required by the Rights Agent, send each Holder at its registered address a copy of such Milestone Notice. At the time the Rights Agent sends a copy of such Milestone Notice to the Holders, the Rights Agent shall also pay to each Holder, subject to any applicable withholding Tax, the applicable Milestone Amount (the amount of which each Holder is entitled to receive shall be based on the applicable Milestone Amount multiplied by the number of CVRs held by such Holder as reflected in the CVR Register), in accordance with the corresponding letter of instruction (i) 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 date of the applicable Milestone Notice or (ii) with respect to any such Holder that is due an amount in excess of $100,000 in the aggregate who has provided the Rights Agent wiring instructions in writing as of the close of business on the date of the Milestone Notice, by wire transfer of immediately available funds to the account specified on such instruction.

(c) Notwithstanding any other provisions of this Agreement, any portion of the amounts payable pursuant to Section 2.4(b) that remains unclaimed as of the first anniversary of the applicable Milestone Payment Date (including by means of uncashed checks or invalid addresses on the CVR Register) shall be delivered to Parent or its designee and not disbursed to the Holders, and, thereafter, such Holders shall be entitled to look to Parent (subject to abandoned property, escheat and other similar Laws) only as general creditors thereof with respect to such cash that may be payable.

If the Rights Agent does not receive from the Acting Holders a written objection to (i) a Milestone Non-Achievement Certificate with respect to Milestone 1, if any, within 180 days of the delivery by the Rights Agent of such Milestone Non-Achievement Certificate to the Holders in accordance with this Section 2.4(e), the Holders shall be deemed to have accepted such Milestone Non-Achievement Certificate and Parent and its Affiliates shall have no further obligation with respect to Milestone 1 and the Xxxxxxxxx 0 Xxxxxx, xxx/xx (xx) a Milestone Non-Achievement Certificate with respect to Milestone 2 and/or Milestone 3, if any, within 180 days of the delivery by the Rights Agent of such Milestone Non-Achievement Certificate with respect the 2024 Calendar Year to the Holders in accordance with this Section 2.4(e), the Holders shall be deemed to have accepted such Milestone Non-Achievement Certificate and Parent and its Affiliates shall have no further obligation with respect to each such Milestone and the applicable Milestone Amount.

2.5. Withholding. Each of Parent, the Rights Agent, the Exchange Agent, the Surviving Corporation, their respective Affiliates, and any other Person who has any obligation to deduct or withhold from any consideration payable pursuant to this Agreement shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Agreement such amounts as are required by any law to be deducted and withheld, as may be reasonably determined by such Person. To the extent that amounts are so withheld and remitted to the appropriate Governmental Body in accordance with applicable Legal Requirements, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

2.6. Adjustment of CVRs.

(a) In case of any Change of Control, appropriate adjustment shall be made in the application of the provisions herein set forth with respect to the rights and interests of Holders so that the provisions set forth herein shall thereafter be applicable, as nearly as possible, in relation to any cash thereafter deliverable upon payment of CVRs.

2.7. Notices to CVR Holders. Upon any adjustment pursuant to Section 2.6, Parent shall give prompt written notice of such adjustment to the Rights Agent and shall cause the Rights Agent, on behalf of and at the expense of Parent, within 10 days after notification is received by the Rights Agent of such adjustment, to mail by first class mail, postage prepaid, to each Holder a notice of such adjustment(s)

Where appropriate, such notice by Parent may be given in advance and included as a part of the notice to the Holders required under the other provisions of this Section 2.7.

2.8. Holding of Funds. All funds received by the Rights Agent under this Agreement that are to be distributed or applied by the Rights Agent in the performance of services hereunder (the “Funds”) shall be held by the Rights Agent as agent for Parent and deposited in one or more bank accounts to be maintained by the Rights Agent in its name as agent for Parent. Until paid pursuant to the terms of this Agreement, the Rights Agent will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Xxxxx’x (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.).

The Rights Agent 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, any Holder or any other Person, unless there is a diminution of the Funds due to a deposit or investment made by the Rights Agent, in which case, the Rights Agent agrees that such interest, dividends or earnings shall accrue to the benefit of Parent to the extent of such diminution of the Funds.

2.9. No Voting, Dividends or Interest; No Equity or Ownership Interest.

(a) Nothing contained in this Agreement shall be construed as conferring upon any Holder, by virtue of being a Holder of a CVR, the right to receive dividends, or the right to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of Parent or any or any other matter, or any other rights of any kind or nature whatsoever as a stockholder of Parent, either at law or in equity.

(b) The CVRs shall not represent any equity or ownership interest in Parent or in any constituent company to the Merger or any of their respective Subsidiaries or Affiliates. The rights of a Holder in respect of the CVRs are limited to those expressed in this Agreement and the Merger Agreement.

2.10. Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Parent or any of its Affiliates without consideration therefor. Nothing in this Agreement shall prohibit Parent 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 Parent or any of its Affiliates shall be automatically deemed extinguished and no longer outstanding for purposes of the definition of Acting Holders and Section 5 and Section 6.

(a) The Rights Agent may resign at any time by giving written notice thereof to Parent specifying a date when such resignation shall take effect, which notice shall be sent at least 60 days prior to the date so specified but in no event shall such resignation become effective until a successor Rights Agent has been appointed and accepted such appointment in accordance with Section 3.4.

Notwithstanding the foregoing, if Parent shall fail to make such appointment within a period of sixty (60) 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 Rights Agent, then the incumbent Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. The successor Rights Agent so appointed shall, forthwith upon its acceptance of such appointment in accordance with Section 3.4, become the successor Rights Agent.

All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

7.6. Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and the application of such provision to other Persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties.
