Company’s receipt of the gross proceeds of the Company’s initial public offering and issuing a press release announcing when
separate trading will begin. No fractional warrants will be issued upon separation of the Units and only whole Warrants will trade. The
terms of the Warrants are governed by a Warrant Agreement, dated as of __________, 2021 (the “Warrant Agreement”), between
the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, and are subject to the terms and provisions contained
