RECITALS:

A. The Company will hold a special meeting of stockholders (the “Meeting”) to consider and act upon, among other things, a proposal (the “Extension Proposal”) to amend the Company’s Amended and Restated Certificate of Incorporation to extend the date by which the Company must consummate an initial business combination (a “Business Combination”) from May 8, 2023 (the “Current Outside Date”) to November 8, 2023 (such date, the “First Extended Date”), and to allow the Company, without another stockholder vote, by resolution of the Company’s board of directors, to elect to further extend the First Extended Date in one-month increments up to three additional times, or a total of up to nine months after the Current Outside Date, until February 8, 2024 (each, an “Additional Extended Date”, and together with the First Extended Date, the “Extension”).

B. The Holder is willing not to request redemption in connection with the Extension, or to reverse any previously submitted redemption demand, of certain of the shares of Class A common stock, par value $0.0001 per share, of the Company (the “Class A Common Stock”) issued in the Company’s initial public offering held by such Holder upon the terms set forth herein.

IT IS AGREED:

1. Non-Redemption. The Holder hereby agrees either not to request redemption in connection with the Extension or to use commercially reasonable efforts to request that the trustee of the Trust Account (as defined below) to reverse any previously submitted redemption demand in connection with the Extension with respect to the aggregate number of shares of Class A Common Stock set forth on Exhibit A hereto (“Non-Redeemed Shares”) it holds; provided that in no event will Holder be required to hold a number of shares of Class A Common Stock representing in excess of 9.9% of the total number of shares of Class A Common Stock of the Company outstanding based on the information set forth in the Redemption Notice (as defined below). The Non-Redeemed Shares held by the Holder shall not be subject to any transfer restrictions other than with respect to the first sentence of this Section 1, and the Holder shall have no obligation to hold any shares of Class A Common Stock following the date of the Meeting. Nothing in this Agreement is intended to restrict or prohibit the Holder’s ability to redeem any shares of Class A Common Stock other than the Non-Redeemed Shares. The Company covenants and agrees to publicly file a Redemption Notice (as defined below) no later than 9:00 AM Eastern Time on the business day prior to the date of the Meeting (or such earlier time as necessary to allow Holder the reasonable opportunity to reverse any previously submitted redemption demand in connection with the Extension).

The “Redemption Notice” is a Current Report on Form 8-K under the Exchange Act that provides (i) the number of shares of Class A Common Stock remaining following the submission and non-reversal of redemption requests following the redemption deadline for the Extension; (ii) the number of unaffiliated parties with whom the Company has entered non-redemption agreements in connection with the Extension; and (iii) the maximum aggregate number of shares of Class A Common Stock that such unaffiliated parties have agreed either not to request redemption in connection with the Extension or to use commercially reasonable efforts to request that the trustee of the Trust Account to reverse any previously submitted redemption demand in connection with the Extension.

2. Forfeiture of Class B Common Stock and Issuance of Class A Common Stock.

(a) In consideration of the agreement set forth in Section 1 hereof, immediately prior to, and substantially concurrently with, the closing of a Business Combination (“Closing”), the Company shall issue (the “Share Issuance”) to the Holder a number of shares of Class A Common Stock equal to the Forfeited Shares (as defined below). The shares of Class A Common Stock shall be issued directly to the Holder in book-entry form on the books and records of the Company’s transfer agent electronically via the Direct Registration System of the Depository Trust Company or in such other manner as the Insider, the Company and the Holder shall agree upon Closing. The shares of Class A Common Stock issued to the Holder pursuant to this Section 2(a) shall be the “Share Issuance Shares”.

(b) In connection with the Share Issuance pursuant to Section 2(a), immediately prior to, and substantially concurrently with, the Closing, the Insider (or its designees) will surrender and forfeit (the “Insider Forfeiture”) to the Company for no consideration the aggregate number of shares of Class B common stock, par value $0.0001 per share, of the Company set forth on Exhibit A held by the Insider (or its designees) (the “Class B Common Stock” and, such shares of Class B Common Stock to be surrendered and forfeited, the “Forfeited Shares”).

(c) In connection with the Share Issuance pursuant to Section 2(a), the Holder shall be entitled to the registration rights set forth in that certain Registration and Stockholders Rights Agreement, dated as of November 3, 2021 (the “Registration Rights Agreement”), among the Insider, the Company and the other parties thereto in respect of all shares held by Holder, and the Company, the Insider and the Holder shall execute a joinder thereto whereby the Holder shall become a “Holder” (as defined therein) and the shares of Class A Common Stock acquired in the Share Issuance shall be “Registrable Securities” (as defined therein).

(d) The Holder shall not be required to forfeit, transfer or refrain from transferring any shares of Class A Common Stock received by it pursuant to Section 2. The Insider acknowledges and agrees that the Insider shall not subject the shares of Class B Common Stock that are required to be surrendered and forfeited pursuant to Section 2(a) to any earn-outs, forfeitures, transfers, surrenders, claw-backs, disposals, exchanges, restrictions, amendments or similar arrangements in connection with the Business Combination, and the Insider and the Company acknowledge and agree that any

2

shares of Class A Common Stock received by the Holder in the Share Issuance shall not be changed or reduced as a result of or subject to any earn-outs, forfeitures, transfers, restrictions, amendments or other arrangements agreed to by the Insider with respect to its other shares of Class B Common Stock.

(e) If at any time the number of outstanding shares of Class A Common Stock or Class B Common Stock of the Company is increased or decreased by a consolidation, combination, split or reclassification of the Class A Common Stock or Class B Common Stock or other similar event, then, as of the effective date of such consolidation, combination, split, reclassification or similar event, all share numbers referenced in this Agreement shall be adjusted in proportion to such increase or decrease in outstanding shares of Class A Common Stock or Class B Common Stock of the Company. For the avoidance of doubt, any redemptions of shares of Class A Common Stock of the Company shall not result in the reduction of the number of Share Issuance Shares to be issued to the Holder.

(e) No General Solicitation. The Company has not offered the shares to be issued in the Share Issuance by means of any general solicitation or general advertising within the meaning of Regulation D of the Securities Act, including but not limited to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media or broadcast over television or radio or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising.

(f) Minimum Number of Non-Redeemers.

7. Entire Agreement: Amendment. This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and may be amended or modified only by written instrument signed by all parties, except for an automatic amendment pursuant to Section 14. The headings in this Agreement are for convenience of reference only and shall not alter or otherwise affect the meaning hereof. If any provision of this Agreement is found to violate any statute, regulation, rule, order or decree of any governmental authority, court, agency or exchange, such invalidity shall not be deemed to affect any other provision hereof or the validity of the remainder of this Agreement, and such invalid provision shall be deemed deleted herefrom to the minimum extent necessary to cure such violation.

8. Governing Law. This Agreement shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation, inducement to enter and/or performance of this Agreement (whether related to breach of contract, tortious conduct or otherwise and whether now existing or hereafter arising) shall be governed by, and construed in accordance with the law of the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other jurisdiction. Any dispute relating hereto shall be heard in the state or federal courts of the State of New York

6

located in New York County, New York, and the parties agree to jurisdiction and venue therein. THE COMPANY, THE INSIDER AND THE HOLDER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY LAWSUIT, CLAIM, OR OTHER PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

9. Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed signature page by facsimile or other electronic transmission shall be effective as delivery of a manually signed counterpart of this Agreement.

10. Termination. This Agreement shall become null and void and of no force and effect upon the earliest to occur of: (a) the date of the Meeting, if any of the Non-Redeemed Shares held by the Holder are actually redeemed in connection with the Meeting, other than as provided for in Section 1; (b) the mutual written consent of the parties hereto; and (c) the effectuation of the Extension and the delivery of the Share Issuance Shares to the Holder (provided that Holder’s rights to have the Share Issuance Shares included in the Registration Rights Agreement and the provisions of Sections 6, 7, 8, 9, 10, 11, 13 and 14 shall survive such termination). Notwithstanding any provision in this Agreement to the contrary, the Insider’s obligation to surrender and forfeit the Forfeited Shares to the Company and the Company’s obligation to issue the equivalent amount of share of Class A Common Stock to the Holder shall only take place immediately prior to, and substantially concurrently with, a Closing.

11. Remedies. Each of the parties hereto acknowledges and agrees that, in the event of any breach of any covenant or agreement contained in this Agreement by another party, money damages may be inadequate with respect to any such breach and the non-breaching party may have no adequate remedy at law. It is accordingly agreed that each of the parties hereto shall be entitled, in addition to any other remedy to which they may be entitled at law or in equity, to seek injunctive relief and/or to compel specific performance to prevent breaches by the other party hereto of any covenant or agreement of such other party contained in this Agreement.

12. Acknowledgement; Waiver. Holder (i) acknowledges that the Insider or the Company may possess or have access to material non-public information which has not been communicated to the Holder; (ii) hereby waives any and all claims, whether at law, in equity or otherwise, that he, she, or it may now have or may hereafter acquire, whether presently known or unknown, against the Insider, the Company or any of their respective officers, directors, employees, agents, affiliates, subsidiaries, successors or assigns relating to any failure to disclose any non-public information in connection with the transaction contemplated by this Agreement, including without limitation, any claims arising under Rule 10b-5 promulgated under the Exchange Act; and (iii) is aware that the Insider and the Company are relying on the truth of the representations set forth in Section 3 of this Agreement and the foregoing acknowledgement and waiver in clauses (i) and (ii) above, respectively, in connection with the transactions contemplated by this Agreement.

13. Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors and permitted assigns. This Agreement shall not be assigned by any party without the prior written consent of the other parties hereto; provided, that no such consent shall be required for any such assignment by Investor to one or more affiliates thereof.

14. Most Favored Nation. In the event the Insider or the Company enters one or more Other Agreements before or after the execution of this Agreement, the Insider and the Company represent that the terms of such Other Agreements will not be materially more favorable to such other investors thereunder than the terms of this Agreement are in respect of the Holder. To avoid doubt, the Company and the Insider acknowledge and agree that a ratio of Non-Redeemed Shares to shares of Class A Common Stock issuable in the Share Issuance in any such Other Agreement in connection with the Extension that is more favorable to such other investors thereunder than such ratio in this Agreement is to the Holder would be materially more favorable to such other investors. In the event that another third party is afforded any such more favorable terms than the Holder, the Insider and the Company shall within one business day inform the Holder of such more favorable terms in writing, and the Holder shall have the right to elect in writing to the Company to have such more favorable terms included herein, in which case this Agreement shall automatically be amended to effect the same.
