  Each Unit (“Unit”) consists of one (1) Class A

      entitles the holder to purchase one (1) Ordinary Share for $11.50 per share (subject to adjustment). Each Warrant will become exercisable on the later of (i) thirty (30) days after the Company’s completion of a merger, share exchange, asset
      acquisition, share purchase, reorganization or other similar business combination with one or more businesses (each, a “Business Combination”), and (ii) twelve (12) months from the closing of the Company’s initial public offering, and will expire
      unless exercised before 5:00 p.m., New York City Time, on the date that is five (5) years after the date on which the Company completes its initial Business Combination, or earlier upon redemption or liquidation (the “Expiration Date”). The Ordinary

      announcing when separate trading will begin. No fractional warrants will be issued upon separation of the Units and only whole warrants are exercisable. 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 Agent, and are subject to the terms and provisions contained therein, all of which terms and provisions the holder of this certificate
