        Corp., a Delaware corporation (the “Company”), and KKR Acquisition Sponsor I LLC, a Delaware limited liability company (the “Purchaser”).

      

      

      WHEREAS, the Company intends to consummate an initial public offering of the Company’s units (the “Public Offering”), each unit consisting of one share of Class A common stock of
        the Company, par value $0.0001 per share (each, a “Share”), and one-fourth of one redeemable warrant, each whole warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share, as

      WHEREAS, the Purchaser has agreed to purchase, at a price of $1.50 per warrant, an aggregate of 19,333,333 warrants (and 2,400,000 additional warrants if the underwriters in the Public Offering exercise their
        over-allotment option in full) (the “Private Placement Warrants”), each Private Placement 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 parties to this Agreement
        hereby, intending legally to be bound, agree as follows:

      C.          Terms of the Private Placement Warrants.

      As a material inducement to the Purchaser to enter into this Agreement and purchase the Private Placement Warrants, the Company hereby represents and warrants to the Purchaser (which representations and warranties

        2

        
          


      

      

      

      A.          Incorporation and Corporate Power. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and is qualified to

        the valid and binding obligation of the Company, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting
        creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law). Upon issuance in accordance with, and payment pursuant to, the terms of the Warrant Agreement and this Agreement, the Private Placement
        Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms as of each Closing Date.

      

      

      (ii)          The execution and delivery by the Company of this Agreement and the Private Placement Warrants, the issuance and sale of the Private Placement Warrants, the issuance of the Shares upon

        effect on the date hereof or as may be amended prior to completion of the Public Offering) or any material law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is
        subject, except for any filings required after the date hereof under federal or state securities laws.

      

      

      C.          Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the Shares issuable upon exercise of the Private
        Placement Warrants will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the Purchaser will have good title to the Private Placement
        Warrants purchased by it and the Shares issuable upon exercise of such Private Placement Warrants, free and clear of all liens, claims and encumbrances of any kind, other than (i) transfer restrictions hereunder and under the other agreements
        contemplated hereby, (ii) transfer restrictions under federal and state securities laws, and (iii) liens, claims or encumbrances imposed due to the actions of the Purchaser.

      
        3

        
          


      

      D.          Governmental Consents. No permit, consent, approval or authorization of, or declaration to or filing with, any governmental authority is required in connection with the execution,
        delivery and performance by the Company of this Agreement or the consummation by the Company of any other transactions contemplated hereby.

      

      

      E.          Regulation D Qualification. Neither the Company nor, to its actual knowledge, any of its affiliates, members, officers, directors or beneficial shareholders of 20% or more of its
        outstanding securities, has experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act.

      

      

      Section 3.          Representations and Warranties of the Purchaser.

      

      

      As a material inducement to the Company to enter into this Agreement and issue and sell the Private Placement Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which
        representations and warranties shall survive each Closing Date) that:

      

      

      A.          Organization and Requisite Authority. The Purchaser possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

      

      

      B.          Authorization; No Breach.

      

      

      (i)          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 affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law).

      

      

      (ii)          The execution and delivery by the Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by the Purchaser does not and shall not as of each Closing Date
        (a) conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of, (b) constitute a default under, (c) result in the creation of any lien, security interest, charge or encumbrance upon the Purchaser’s equity or

        instrument, order, judgment or decree to which the Purchaser is subject, except for any filings required after the date hereof under federal or state securities laws.

      

      

      C.          Investment Representations.

      

      

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

      
        4

        
          


      

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

      

      

      (iii)          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.

      

      

      (iv)          The Purchaser did not decide to 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.

      

      

      (v)          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.

      

      

      (vi)          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.

      

      

      (vii)          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 and Stockholder 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 SEC
        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 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.

      
        5

        
          


      

      (viii)          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.

      

      

      Section 4.          Conditions of the Purchaser’s Obligations.

      

      

      The obligations of the Purchaser to purchase and pay for the Private Placement Warrants are subject to the fulfillment, on or before each Closing Date, of each of the following conditions:

        Agreement.

      D.          No Injunction. No litigation, statute, rule, regulation, executive order, decree, ruling or injunction shall have been enacted, entered, promulgated or endorsed by or in any court
        or governmental authority of competent jurisdiction or any self-regulatory organization having authority over the matters contemplated hereby, which prohibits the consummation of any of the transactions contemplated by this Agreement or the Warrant
        Agreement.

      

      

      E.          Warrant Agreement and Registration and Stockholder Rights Agreement. The Purchaser shall have entered into the Warrant Agreement and the Registration and Stockholder Rights
        Agreement, in each case on terms satisfactory to the Company.

      C.          Counterparts. This Agreement may be executed simultaneously in two or more counterparts, none of which need contain the signatures of more than one party, but all such counterparts
        taken together shall constitute one and the same agreement. A signed copy of this Agreement delivered by facsimile, e- mail or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed
        copy of this Agreement.
