      Delaware corporation (the “Company”), 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 7,850,000 warrants (or up to 8,637,500 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 receipt and sufficiency of which are hereby acknowledged, 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.

      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

        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”).

    Section 3.01          Organization and Requisite Authority.  The Purchaser is a limited liability company duly formed, validly existing and in good standing under the laws of the State of

          	Section 3.02	
            Authorization; No Breach.

          	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.”
