WHEREAS, at a special meeting of stockholders of the Company held on June 22, 2023, the Company stockholders approved a proposal to amend (the “Third Extension Amendment”) the Company’s amended and restated certificate of incorporation, (the “Amended Charter”) to allow the Company to (i) initially extend the date by which the Company must consummate an initial business combination up to six times, each such extension for an additional one month period, until December 31, 2023, by depositing into the trust account established in connection with the Company’s initial public offering (the “Trust Account”) the amount of $85,000 for each one-month extension, until December 31, 2023, and (ii) further extend the date by which the Company must consummate an initial business combination (without seeking additional approval from the stockholders) for up to an additional three months, from January 1, 2024 to March 31, 2024, with no additional deposits to be made into the Trust Account during such period, each such extension for an additional one month period, (the “Third Extended Date”), upon one calendar day advance notice to the Trustee, prior to the applicable monthly deadline, unless the closing of the proposed initial business combination with Clearday, Inc., or any potential alternative initial business combination shall have occurred prior to the Third Extended Date; and
