The Warrant will become exercisable on the later of (i) the completion of a Business Combination (as such term is defined in the Warrant Agreement), and (ii) one year after the date of the consummation of the Public Offering (as defined in the Warrant Agreement), and will expire unless exercised before 5:00 p.m., New York City time, [five years after the date of the consummation of the Public Offering] , or earlier upon redemption (the “Expiration Date”). The Common Stock and the Warrant comprising the Units represented by this certificate are not transferable separately prior to five (5) business days (or as soon as practicable thereafter) following the earliest to occur of (x) the expiration or termination of the underwriters' over-allotment option, (y) its exercise in full, and (z) the underwriters' determination not to exercise all or any remaining portion of the over-allotment option, subject in each case to the Corporation having filed a Current Report on Form 8-K with the Securities and Exchange Commission, containing an audited balance sheet reflecting the Corporation's receipt of the gross proceeds of the Public Offering and issuing a press release announcing when such separate trading will begin. The terms of the Warrants are governed by the Warrant Agreement (the “Warrant Agreement ”), dated as of [], between the Corporation and Continental Stock Transfer & Trust Company (the “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.
