represented by this certificate are not transferable separately until 52 days following the date of the final prospectus relating to the
IPO, unless the underwriters inform the Company of their decision to allow earlier separate trading, except that in no event will the
Class A Ordinary Shares and Warrants be separately tradeable until the Company has filed with the United States Securities and Exchange
Commission a Current Report on Form 8-K which includes an audited balance sheet reflecting the Company’s receipt of the gross proceeds
at the closing of its IPO and issued a press release announcing when such separate trading will begin. The terms of the Warrants are governed
by a Warrant Agreement, dated as of [•], 2021, between the Company and Continental Stock Transfer & Trust Company, as Warrant
