      and Mercury Ecommerce Sponsor Group I LLC, a Delaware limited liability company (the “Purchaser”).

    

    

    WHEREAS, the Company intends to consummate a public offering of the Company’s units (the “Public Offering”), each unit consisting of one share of the Company’s Class A common stock, par value $0.0001 per share (a “Share”),
      and one-half of one warrant, each whole warrant exercisable for one Share at an exercise price of $11.50 per Share, as set forth in the Company’s registration statement on Form S-1 related to the Public Offering (the “Registration Statement”); and

    

    

    WHEREAS, the Purchaser has agreed to purchase from the Company an aggregate of 6,100,000 warrants (or up to 6,625,000 warrants if the
      over-allotment option in connection with the Public Offering is exercised in full) (the “Warrants”), each Warrant entitling the holder to purchase one Share at
      an exercise price of $11.50 per Share.

    

    

    NOW, THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the

    Section 1.01          Authorization of the Warrants.  The Company has duly authorized the issuance and sale of the Warrants and, subject to proper exercise of the Warrants and against
        payment therefor, the Shares underlying such Warrants, to the Purchaser.

    

    

    	

          	Section 1.02

        the 6,100,000 Warrants being purchased under this Agreement, each Purchaser shall pay $6,100,000 (the “Purchase Price”), by wire transfer of immediately
        available funds, to the trust account (the “Trust Account”) at a financial institution to be chosen by the Company, maintained by J.P. Morgan Chase Bank,
        N.A. with Continental Stock Transfer & Trust Company acting as trustee, at least one (1) business day prior to the Initial Closing Date (as defined below) or on such earlier time and date as may be mutually agreed by the Purchaser and the

    (b)          In the event that the
        over-allotment option is exercised in full or in part, the Purchaser shall purchase up to an additional 525,000 Warrants (the “Additional Warrants”), in the
        same proportion as the amount of the over-allotment option that is exercised, and simultaneously with such purchase of Additional Warrants, as payment in full for the Additional Warrants being purchased hereunder, and at least one business day
        prior to the Over-allotment Closing Date (as defined below), Purchaser shall pay $1.00 per Additional Warrant, up to an aggregate amount of approximately $525,000, by wire transfer of immediately available funds, to the Trust Account.

        purchase and sale of the Warrants shall take place simultaneously with the closing of the Public Offering or on such earlier time and date as may be mutually agreed by the Purchaser and the Company (the “Initial Closing Date”).  The closing of the purchase and sale of the Additional Warrants, if applicable, shall take place simultaneously with the closing of all or any portion of the over-allotment
        option or on such earlier time and date as may be mutually agreed by the Purchaser and the Company (such closing date, the “Over-allotment Closing Date” and
        together with the Initial Closing Date, the “Closing Dates” and each, a “Closing
            Date”).  The closing of the purchase and sale of each of the Warrants and the Additional Warrants shall take place at the offices of Sidley Austin LLP, 1000 Louisiana, Suite 5900, Houston, Texas, 77002, or such other place as may be

          issuable upon exercise of the Warrants) will not, except in limited circumstances, be transferable or salable until 30 days after the completion of the Company’s initial business combination (the “Business Combination”) so long as they are held by the Purchaser or its permitted

          they are registered pursuant to the Registration Rights Agreement (as defined below) or an exemption from registration is available, and the restrictions described above in clause (i) have expired and (iii) each Warrant shall have the terms set
          forth for private placement warrants in  Warrant Agreement to be entered into by the Company and a warrant agent in connection with the Public Offering (the “Warrant Agreement”).

    

    

    (b)          At or prior to the time
        of the Initial Closing Date, the Company and the Purchaser shall enter into a registration rights agreement (the “Registration Rights Agreement”) pursuant to
        which the Company will grant certain registration rights to the Purchaser relating to the Warrants and the Shares underlying the Warrants.

    (a)          This Agreement
        constitutes a valid and binding obligation of the Purchaser, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or

          	Section 3.03	
            Investment Representations.

          


    

    

    (a)          The Purchaser is
        acquiring the Warrants and, upon exercise of the Warrants, the Shares issuable upon such exercise (collectively, the “Securities”), for the Purchaser’s own
        account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

    

    

    (b)          The Purchaser is an
        “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and the
        Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act.

    
      3

      
        


    

    

    

    (c)          The Purchaser understands
        that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy
        of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.

    

    

    (d)          The Purchaser did not
        enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.

    

    

    (e)          The Purchaser has been
        furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser.  The Purchaser has been afforded the
        opportunity to ask questions of the executive officers and directors of the Company.  The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has
        considered necessary to make an informed investment decision with respect to the acquisition of the Securities.

    

    

    (f)          The Purchaser understands
        that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the
        Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

    

    

    (g)          The Purchaser understands
        that:  (a) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in
        reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state
        securities laws or to comply with the terms and conditions of any exemption thereunder.  In this regard, the Purchaser understands that the Securities and Exchange Commission has taken the position that promoters or affiliates of a blank check
        company and their transferees, both before and after an initial business combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company.  Based on that position, Rule 144 adopted
        pursuant to the Securities Act would not be available for resale transactions of the Securities despite technical compliance with the certain requirements of such Rule, and the Securities can be resold only through a registered offering or in
        reliance upon another exemption from the registration requirements of the Securities Act.

    

    

    (h)          The Purchaser has such
        knowledge and experience in financial and business matters, knowledge of the high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks
        of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an indefinite period of time.  The Purchaser has adequate means of providing for its current
        financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities.  The Purchaser can afford a complete loss of its investments in the Securities.

    

    

    (i)          The Purchaser understands
        that the Private Placement Warrants shall bear the legend substantially in the form set forth in the Warrant Agreement and be subject to appropriate “stop transfer restrictions.”
