NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Subscription. Subject to the terms and conditions hereof, Subscriber hereby agrees to subscribe for and purchase, and the Issuer hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Acquired Shares (such subscription and issuance, the “Subscription”).

2. Closing.

a. Subject to the satisfaction or waiver of the conditions set forth in Section 2(c), (d), and (e), the closing of the Subscription contemplated hereby (the “Closing”) shall occur on the date of, and at a time immediately prior to, the closing of the Transaction (such date, the “Closing Date”). Not less than ten (10) business days prior to the date the Company reasonably expects the Closing Date to occur (the “Scheduled Closing Date”), the Issuer shall provide written notice to Subscriber (the “Closing Notice”) of the Scheduled Closing Date. The Closing Notice shall contain the Issuer’s wire instructions for an escrow account (the “Escrow Account”) established by the Issuer with a third-party escrow agent (the “Escrow Agent”) to be identified in the Closing Notice. At least five (5) business days prior to the Scheduled Closing Date (unless otherwise agreed to in writing by the Issuer or unless Subscriber gives notice of any issues related to the Transaction Documents that would have a material adverse impact on Subscriber), Subscriber shall deliver to the Escrow Account the cash portion of the Purchase Price for the Acquired Shares subscribed by wire transfer of United States dollars in immediately available funds. The wire transfer shall identify Subscriber, and unless otherwise agreed by the Issuer and the Escrow Agent, the funds shall be wired from an account in Subscriber’s name. Upon the Closing, the Issuer shall provide instructions to the Escrow Agent to release the funds in the Escrow Account to the Issuer against the issuance of and delivery to Subscriber of the Acquired Shares, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws or those incurred by Subscriber), in book-entry form as set forth in Section 2(b) below. In the event the Closing does not occur within three (3) business days of the Scheduled Closing Date, or in the event the Combination Agreement is terminated, the Issuer shall promptly (but not later than two (2) business days thereafter) return the Purchase Price to Subscriber. The failure of the Closing to occur on the Scheduled Closing Date shall not terminate this Subscription Agreement or otherwise relieve any party of any of its obligations hereunder, including Subscriber’s obligation to purchase the Acquired Shares following the Issuer’s delivery of a new Closing Notice.

but no later than the earlier of (i) the 60th calendar day (or 90th calendar day if the Commission notifies the Issuer that it will “review” the Registration Statement) following the Closing and (ii) the 10th business day after the date the Issuer is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”); provided, however, that the Issuer’s obligations to include the Acquired Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Issuer such information regarding Subscriber, the securities of the Issuer held by Subscriber and the intended method of disposition of the Acquired Shares as shall be reasonably requested by the Issuer to effect the registration of the Acquired Shares, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided further that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Acquired Shares. For purposes of clarification, any failure by the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth above in this Section 6. Further, Issuer shall be liable to Subscriber, not as a penalty but as liquidated damages, for any failure of Issuer to file the Registration Statement by the Filing Date, in the amount of two percent (2%) of the Purchase Price per Business Day of delay. The Issuer will provide a draft of the Registration Statement to the undersigned for review at least five (5) business days in advance of filing the Registration Statement. In no event shall the undersigned be identified as a statutory underwriter in the Registration Statement unless requested by the SEC. Notwithstanding the foregoing, if the SEC prevents the Issuer from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Acquired Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Acquired Shares which is equal to the maximum number of Acquired Shares as is permitted by the SEC. In such event, the number of Acquired Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders. Upon notification by the Commission that the Registration Statement has been declared effective by the Commission, within one (1) business day thereafter, the Issuer shall file the final prospectus under Rule 424 of the Securities Act.

b. In the case of the registration, qualification, exemption or compliance effected by the Issuer pursuant to this Subscription Agreement, the Issuer shall, upon reasonable request, inform Subscriber as to the status of such registration, qualification, exemption and compliance. At its expense the Issuer shall:

(i) except for such times as the Issuer is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Issuer determines to obtain, continuously effective with respect to Subscriber, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (i) Subscriber ceases to hold any Acquired Shares or (ii) the date all Acquired Shares held by Subscriber may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for the Issuer to be in compliance with the current public information required under Rule 144(c)(1) or Rule 144(i)(2), as applicable, and (iii) two years from the Effective Date of the Registration Statement. The period of time during which the Issuer is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period.”

(ii) advise Subscriber within two (2) business days:

(1) when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(2) of any request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;

(3) of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

9

(4) of the receipt by the Issuer of any notification with respect to the suspension of the qualification of the Acquired Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(5) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, the Issuer shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Issuer other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (1) through (5) above constitutes material, nonpublic information regarding the Issuer;

(iii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) upon the occurrence of any event contemplated above, except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Issuer shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Acquired Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(v) use its commercially reasonable efforts to cause all Acquired Shares to be listed on each securities exchange or market, if any, on which the Series A Shares issued by the Issuer have been listed;

(vi) use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Acquired Shares contemplated hereby and to enable Subscriber to sell the Acquired Shares under Rule 144; and

(vii) cause the Issuer’s transfer agent to remove the legend set forth above in Section 2(b), at the Subscriber’s request, when the Acquired Shares are sold pursuant to Rule 144 under the Securities Act or the Registration Statement. In connection therewith, if required by the Issuer’s transfer agent, the Issuer will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to issue such Acquired Shares without any such legend.

c. Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Issuer’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Issuer in the Registration Statement of material information that the Issuer has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Issuer’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that the Issuer may not delay or suspend the Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from the Issuer of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Acquired Shares under the Registration Statement (excluding,

10

for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Issuer agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Issuer that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Issuer unless otherwise required by law or subpoena. If so directed by the Issuer, Subscriber will deliver to the Issuer or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Acquired Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Acquired Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

d. Subscriber may deliver written notice (an “Opt-Out Notice”) to the Issuer requesting that Subscriber not receive notices from the Issuer otherwise required by this Section 6; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) the Issuer shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement, Subscriber will notify the Issuer in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 6(d)) and the related suspension period remains in effect, the Issuer will so notify Subscriber, within one (1) business day of Subscriber’s notification to the Issuer, by delivering to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability.

e. The Issuer shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), the officers, directors and agents of Subscriber, and each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Issuer of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 6, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly for use therein or Subscriber has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder; provided, however, that the indemnification contained in this Section 6 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Issuer (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Issuer be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished by Subscriber, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by the Issuer in a timely manner or (C) in connection with any offers or sales effected by or on behalf of Subscriber in violation of Section 6(c) hereof. The Issuer shall notify Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6 of which the Issuer is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the Transfer of the Shares by Subscriber.

f. Subscriber shall, severally and not jointly, indemnify and hold harmless the Issuer, its directors, officers, agents and employees, and each person who controls the Issuer (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, (i) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any

11

Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or (ii) arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, with respect to (i) and/or (ii), to the extent, but only to the extent, that such untrue or alleged untrue statements or omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly for use therein; provided, however, that the indemnification contained in this Section 6(f) shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed). In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Shares giving rise to such indemnification obligation. Subscriber shall notify the Issuer promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6(f) of which Subscriber is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the Transfer of the Shares by Subscriber.

7. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Combination Agreement is terminated in accordance with the terms therein, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) if any of the conditions to Closing set forth in Section 2(c), (d), and (e) are not satisfied on or prior to the Closing Date and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated at the Closing or (d) at the election of Subscriber, on or after the date that is 180 days after the date hereof if the Closing has not occurred on or prior to such date; provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover out-of-pocket losses, liabilities or damages arising from such breach. The Issuer shall promptly notify Subscriber of the termination of the Combination Agreement promptly after the termination of such agreement.

8. Trust Account Waiver. Subscriber acknowledges that the Issuer is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving the Issuer and one or more businesses or assets. Subscriber further acknowledges that, as described in the Issuer’s prospectus relating to its initial public offering dated January 13, 2022 (the “Prospectus”), available at www.sec.gov, substantially all of the Issuer’s assets consist of the cash proceeds of the Issuer’s initial public offering and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of the Issuer, its public stockholders and the underwriters of the Issuer’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Issuer to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus. For and in consideration of the Issuer entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Subscriber, on behalf of itself and its representatives, hereby irrevocable waives any and all right, title and interest, or any claim of any kind they have or may have in the future arising out of this Subscription Agreement, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right, title, interest or claim to the Trust Account by virtue of such Subscriber’s record or beneficial ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement, including but not limited to any redemption right with respect to any such securities of the Issuer.

Section 5.6. Entire Agreement. This Agreement and the Subscription Agreement contain the entire agreement between the parties with respect to the subject matter hereof and thereof and supersede all prior and contemporaneous arrangements or understandings, whether written or oral, with respect hereto and thereto.

Section 5.7. Headings; Nouns and Pronouns; Section References. Headings in this Agreement are for convenience of reference only and shall not be considered in construing this Agreement. Whenever the context may require, any pronouns used herein shall include the corresponding masculine, feminine or neuter forms, and the singular form of names and pronouns shall include the plural and vice-versa. References in this Agreement to a section or subsection shall be deemed to refer to a section or subsection of this Agreement unless otherwise expressly stated.

Section 5.8. Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid or unenforceable provision, the parties shall negotiate in good faith a substitute legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as possible and as reasonably acceptable to the parties.

Section 5.9. Assignment. Neither this Agreement nor any of the rights or obligations hereunder may be assigned by any party to this Agreement without the prior written consent of the other party to this Agreement.

Section 5.10. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

Section 5.11. Counterparts. This Agreement may be executed in multiple counterparts and transmitted by facsimile, by electronic mail in portable document format (“PDF”) form or by any other electronic means intended to preserve the original graphic and pictorial appearance of a party’s signature, with each such counterpart, facsimile or PDF signature constituting an original that shall create a valid and binding obligation of the party executing it (or on whose behalf such signature page is executed) and all of which together shall constitute one and the same original.

Section 5.12. Third Party Beneficiaries. None of the provisions of this Agreement shall be for the benefit of or enforceable by any third party, including any creditor of any party hereto. No third party shall obtain any right under any provision of this Agreement or shall by reason of any such provision make any claim in respect of any debt, liability or obligation (or otherwise) against any party hereto.

Section 5.13. No Strict Construction. This Agreement has been prepared jointly and will not be construed against any party.

Section 5.14. Remedies. The rights, powers and remedies of the parties under this Agreement are cumulative and not exclusive of any other right, power or remedy which such parties may have under any other Contract or law. No single or partial assertion or exercise of any right, power or remedy of a party hereunder shall preclude any other or further assertion or exercise thereof. The parties hereby acknowledge and agree that the rights of the parties hereunder are special, unique and of extraordinary character, and that if any party refuses or otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, such refusal or failure would result in irreparable injury to such party as the case may be, the exact amount of which would be difficult to ascertain or estimate and the remedies at law for which would not be reasonable or adequate compensation. Accordingly, if any party refuses or otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, then, in addition to any other remedy which may be available to any damaged party at law or in equity, such damaged party will be entitled to seek specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual or threatened damages, which remedy such damaged party will be entitled to seek in any court of competent jurisdiction.

Section 5.15. Expenses. Each party shall pay its own fees and expenses in connection with the preparation, negotiation, execution, delivery and performance of this Agreement.
