Each Warrant will become exercisable on the later of (i) thirty (30) days after the Company’s completion of a merger, capital stock exchange, asset acquisition, stock 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 Common Stock and Warrants comprising the Units represented by this certificate are not transferable separately prior to                   , 2021, unless Citigroup Global Markets Inc. elects to allow earlier separate trading, subject to the Company’s 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 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 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 consents to by acceptance hereof. Copies of the Warrant Agreement are on file at the office of the Warrant Agent at 1 State Street, 30th Floor, New York, New York 10004, and are available to any Warrant holder on written request and without cost.

Upon the consummation of the Business Combination, the Units represented by this certificate will automatically separate into the Class A Common Stock and Warrants comprising such Units.
