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 the later of (x) December 29, 2022, and (y) the date and time of the effectiveness of this Amendment (such date and time, the “Amended Termination Time”), and (iii) the redemption of shares in connection with a vote seeking to amend such provisions of this Second Amended and Restated Certificate as described in Section 9.7.Holders of shares of Common Stock included as part of the units sold in the Offering (the “Offering Shares”) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are the Sponsor or officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as “Public Stockholders.”

6.     The phrase “within 24 months from the closing of the Offering” in Section 9.2(d) of Article IX is hereby deleted in its entirety and replaced with the phrase “by the Amended Termination Time”.

7.     The phrase “within 24 months from the closing of the Offering” in Section 9.7 of Article IX is hereby deleted in its entirety and replaced with the phrase “by the Amended Termination Time”.

IN WITNESS WHEREOF, the Corporation has caused this Amendment to the Amended and Restated Certificate of Amendment to be duty executed in its name and on its behalf by an authorized officer as of this 29 day of December, 2022.
