(each whole warrant, a “Warrant”). Each Warrant entitles the holder to purchase one (1) Class A 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

filing with the Securities and Exchange Commission of a Current Report on Form 8-K containing an audited balance sheet reflecting the
Company’s receipt of the gross proceeds of the 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 are exercisable. The terms of the
Warrants are governed by a Warrant Agreement, dated as of [●], 2021, between the Company and VStock Transfer, LLC, as Warrant Agent,
and are subject to the terms and provisions contained therein, all of which terms and provisions the holder of this certificate consents
to by acceptance hereof. Copies of the Warrant Agreement are on file at the office of the Warrant Agent at 18 Lafayette Place, Woodmere,
New York 11598, and are available to any Warrant holder on written request and without cost.
