“(b) Immediately after the Offering, a certain amount of the net offering proceeds received by the Corporation in the Offering (including the proceeds of any exercise of the underwriters’ overallotment option) and certain other amounts specified in the Corporation’s registration statement on Form S-1, initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 12, 2021, as amended (the “Registration Statement”), shall be deposited in a trust account (the “Trust Account”), established for the benefit of the Public Stockholders (as defined below) pursuant to a trust agreement described in the Registration Statement. Except for the withdrawal of interest to pay taxes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earliest to occur of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation is unable to complete its initial Business Combination by September 29, 2023 and (iii) the redemption of shares in connection with a vote seeking to amend such provisions of this Amended and Restated Certificate as described in Section 9.7.

7. The text of Section 9.7 of Article IX of the Amended and Restated Certificate of Incorporation is hereby amended and restated to read in its entirety as follows:

If, in accordance with Section 9.1(a), any amendment is made to this Amended and Restated Certificate (a) to modify the substance or timing of the Corporation’s obligation to redeem 100% of the Offering Shares if the Corporation has not consummated an initial Business Combination by September 29, 2023 or (b) with respect to any other material provisions of this Amended and Restated Certificate relating to stockholders’ rights or pre-initial Business Combination activity, the Public Stockholders shall be provided with the opportunity to redeem their Offering Shares upon the approval of any such amendment, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest not previously released to the Corporation to pay its taxes, divided by the number of then outstanding Offering Shares; provided, however, that any such amendment will be voided, and this Article IX will remain unchanged, if any stockholders who wish to redeem are unable to redeem due to the Redemption Limitation.”

IN WITNESS WHEREOF, the Corporation has caused this Amendment to the Amended and Restated Certificate of Amendment to be duly executed in its name and on its behalf by an authorized officer as of this 22^nd day of May, 2023.
