      UNITS CONSISTING OF ONE SHARE OF CLASS A COMMON STOCK AND ONE-HALF OF ONE WARRANT TO PURCHASE ONE SHARE OF CLASS A COMMON STOCK

      

      

      THIS CERTIFIES THAT                  is the owner of                   Units.

      

      

      Each Unit (“Unit”) consists of one (1) share of Class A common stock, par value $0.0001 per share (“Common Stock”), of Jackson Acquisition Company, a Delaware corporation (the “Company”), and one-half (1/2) of one warrant (each whole warrant, a
        “Warrant”). Each whole Warrant entitles the holder to purchase one (1) share (subject to adjustment) of Common Stock for $11.50 per share (subject to adjustment). Only whole Warrants are exercisable. Each Warrant will become exercisable commencing
        on the later of (i) the date that is thirty (30) days after the Company’s completion of its initial merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses
        (the “Business Combination”), and (ii) twelve (12) months from the date of the closing of the Company’s initial public offering, and, unless exercised earlier, will expire at 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 of the Warrants or the Company’s liquidation. The shares of Common Stock and Warrants comprising the Units represented by this certificate are not
        transferable separately prior to [●], 2022, unless BofA Securities, Inc. elects to allow separate trading earlier, subject to the Company’s filing of a Current Report on Form 8-K with the Securities and Exchange Commission containing an audited
        balance sheet reflecting the Company’s receipt of the gross proceeds of its initial public offering and the Company 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 will trade following such separation. In addition, the Units will automatically separate into their component parts and will not be traded after completion of the initial Business Combination.  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 (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. Copies of the Warrant Agreement are on file at the office of the Warrant Agent at One State Street 30th Floor, New York, New York 10004, and are
        available to any Warrant holder on written request and without cost.

      

      

      This certificate is not valid unless countersigned by the Transfer Agent and Registrar of the Company.

      

      

      This certificate shall be governed by and construed in accordance with the internal laws of the State of New York.
