              Engagement of Services

            


      
        

        

        Dear [●]:

        

        

        This will confirm the basis upon which KKR Acquisition Holdings I Corp. (“Client”) has engaged KKR Capital Markets LLC (“KCM”)
          to provide independent financial consulting services, consisting of a review of deal structure and terms and related structuring advice, as well as to assist the Client with selecting underwriters, in connection with the transaction described in
          paragraph 1 below (the “Engagement”).

        

        

      

      
        1. Fee. The Client shall pay KCM a fee in an amount equal to (a) 50% of the non-deferred underwriting commissions payable to the underwriters, which shall be paid to KCM upon the consummation of the initial
          public offering of the securities of the Client (the “Transaction” and such consummation of the initial issuance of securities, the “Closing”)
          and (b) 50% of the deferred underwriting commissions payable to the underwriters, which will be paid to KCM upon the closing of an initial business combination (the “Fees”). The Fees
          are compensation for the Engagement, which consists of work directly related to the Transaction. Any work that is outside of the scope of the Engagement shall be subject to additional compensation as separately agreed by the parties hereto.

        

        

        2. Term of Engagement. This Agreement shall remain in force for a period of twelve (12) months from the date hereof, or until 45 days following the consummation of the Transaction, whichever occurs earlier,
          and may be extended upon mutual agreement of the parties hereto (including any renewal thereof, the “Term”). The Term may be terminated by either KCM or the Client at any time prior to
          its expiration with forty-five (45) days advance written notice to the other. Expiration or termination of this Agreement shall not affect KCM’s right to indemnification or contribution or payment of the Fees in accordance with the terms of this
          Agreement. Without limiting the foregoing, notwithstanding the expiration or termination of this Agreement, the provisions of this Agreement shall survive and remain operative in accordance with their respective terms.

        

        

        3. Scope of Liability. Neither KCM (nor any of its control persons, members, managers, officers, employees, agents or affiliates) shall be liable to the Client or to any other person claiming through the
          Client for any error of judgment or for any claim, loss or expense suffered by the Client or any such other person in connection with the matters to which the Engagement relates except to the extent a claim, loss or expense arises out of or is
          based upon any action or failure to act by KCM or any of its control persons, members, managers, officers, employees, agents or affiliates, other than an action or failure to act undertaken at the request or with the consent of the Client, that
          is found in a final judicial determination (or a settlement tantamount thereto) to constitute bad faith, willful misconduct or gross negligence on the part of KCM or any such other person.

        

        

        4. Indemnity and Contribution. Recognizing that transactions of the type contemplated by the Engagement sometimes result in litigation and that KCM’s role is limited to acting in the capacities described
          herein, the Client agrees to indemnify KCM and its control persons, members, managers, officers, employees, agents and affiliates (each, including KCM, an “Indemnified Person”) to the
          full extent lawful against any and all claims, losses and expenses as incurred (including all reasonable fees and disbursements of each such Indemnified Person’s counsel and all reasonable travel and other out-of-pocket expenses incurred by each
          such Indemnified Person in connection with investigation of and preparation for any such pending or threatened claims and any litigation or other proceedings arising therefrom) arising out of any actual or proposed Transaction or the Engagement;
          provided; however, there shall be excluded from such indemnification any such claim, loss or expense that arises primarily out of or is based primarily upon any action or failure to act by any Indemnified Person, other than an
          action or failure to act undertaken at the request or with the consent of the Client, that is found in a final judicial determination (or a settlement tantamount thereto) to constitute bad faith, willful misconduct or gross negligence on the part
          of any Indemnified Person.

      

      
        
          


      

      
        

        

      

      
        The Client shall be notified in writing by KCM if any action, suit or investigation (an “Action”) is commenced against KCM or, so long as KCM has actual knowledge of such Action, any
          other Indemnified Person, within a reasonable time after KCM or any other Indemnified Person shall have been served with a summons or other first legal process, but failure so to notify the Client shall not relieve the Client from any liability
          that it may have hereunder, except to the extent that such failure so to notify the Client materially prejudices the Client’s rights. The Client may assume, at its own expense, the defense of any Action exercisable upon written notice to KCM and
          any such Indemnified Person(s), if applicable, within 30 days of notice by KCM or such Indemnified Person provided pursuant to the preceding sentence and the Client will have no liability for any legal costs of such Indemnified Person
          subsequently incurred except as set forth below, and such defense shall be conducted by counsel chosen by the Client and reasonably satisfactory to KCM and such Indemnified Person(s), if applicable. The Indemnified Person shall have the right to
          participate in the defense of any Action with counsel selected by it subject to the Client’s right to control the defense thereof. The fees and disbursements of such counsel shall be at the expense of the Indemnified Person, provided, that if in the reasonable opinion of counsel to the Indemnified Person, (a) there are legal defenses available to an Indemnified Person that are different from or additional to those available to the
          Client; or (b) there exists an actual conflict of interest between the Client and the Indemnified Person that cannot be waived, the Client shall be liable for the reasonable fees and expenses of counsel to the Indemnified Person in each
          jurisdiction for which the Indemnified Person determines counsel is required). If the Client elects not to compromise or defend such Action, fails to promptly notify the Indemnified Person in writing of its election to defend as provided in this
          Agreement, or fails to diligently prosecute the defense of such Action, the Indemnified Person may, subject to the next paragraph, pay, compromise, defend such Action and seek indemnification for any and all damages, expenses, liabilities and
          losses based upon, arising from or relating to such Action. The parties hereto and their affiliates shall cooperate with each other in all reasonable respects in connection with the defense of any Action.

        

        

        Notwithstanding any other provision of this Agreement, the Client shall not enter into settlement of any Action without the prior written consent of the Indemnified Person except as provided in this paragraph. If a firm offer is made to settle
          an Action without permitting or leading to further claims, losses, liability or expense or the creation of a financial or other obligation on the part of any Indemnified Person and provides, in customary form, for the unconditional release of
          each Indemnified Person from all liabilities and obligations in connection with such Action and the denial of culpability by each Indemnified Person and the Client desires to accept and agree to such offer, the Client shall give written notice to
          that effect to the Indemnified Person. If the Indemnified Person fails to consent to such firm offer within ten (10) days after its receipt of such notice, the Indemnified Person may continue to contest or defend such Action and in such event,
          the maximum liability of the Client as to such Action shall not exceed the amount of such settlement offer plus the Indemnified Person’s costs and expenses (including reasonable fees and disbursements of counsel and other out-of-pocket expenses)
          through the end of such ten (10) day period. If the Indemnified Person fails to consent to such firm offer to settle and also fails to assume the defense of such Action, the Client may settle the Action upon the terms set forth in such firm offer
          to settle such Action. If the Indemnified Person has assumed the defense pursuant to the previous paragraph, the Indemnified shall not agree to any settlement in an amount exceeding the liability of the Client in the original firm offer to settle
          without the written consent of the Client.

        

        

        In the event that the foregoing indemnity is unavailable or insufficient to hold such Indemnified Person(s) harmless, then the Client shall contribute to amounts paid or payable by such Indemnified Person(s) in respect of such claims, losses
          and expenses in such proportion as appropriately reflects the relative benefits received by, and fault of, the Client and such Indemnified Person(s) in connection with the matters as to which such claims, losses and expenses relate and other
          equitable considerations.

        

        

      

      
        5. Information Provided to KCM. In performing the services described above, the Client agrees to furnish or cause to be furnished to KCM such information as KCM reasonably believes appropriate to permit KCM
          to provide the services contemplated by this Agreement to or for the Client (all such information so furnished being the “Information”). The Client recognizes and confirms that KCM (a)
          will use and rely primarily on the Information and on information available from generally recognized public sources in performing the services contemplated hereby without having independently verified any of the same, (b) does not assume
          responsibility for the accuracy or completeness of the Information and such other information, and (c) will not make any appraisal of any of the assets or liabilities of the Client.

      

      
        
          


      

      
        

        

        6. Confidentiality. In the event of the consummation and public disclosure of any Transaction, KCM shall have the right to disclose its participation in the Transaction by listing the client name and logo
          on its website and in its marketing materials.

      

      

      

      
        Except as required by law or regulation, or pursuant to order of a court of competent jurisdiction, no analysis, information or advice, whether communicated in written, electronic, oral or other form, provided by KCM to Client or to its Client
          Representatives or its affiliates (as such term is defined below) in connection with the Engagement (the “KCM Information”) shall be disclosed by the Client or such Client
          Representatives, in whole or in part, to any third party, or circulated or referred to publicly, or used for any purpose other than in connection with the Engagement and the Transaction without the prior written consent of KCM. Except as required
          by law or regulation, or pursuant to order of a court of competent jurisdiction, or as otherwise publicly disclosed, neither party may disclose to any third party the existence or terms of this Agreement without the prior written consent of the
          other party. Notwithstanding anything herein to the contrary, the fact of KCM’s Engagement may be disclosed by the Client to its affiliates and its directors, officers, accountants, legal advisors and employees (the “Client Representatives”) to the extent required for the exclusive purpose of the Engagement or as required by law, rule or regulation. KCM’s Engagement, including this Agreement, may be disclosed in the
          Client’s registration statement, preliminary prospectus, prospectus and each amendment or supplement to any of them, as filed with the Securities and Exchange Commission; provided that each reference to KCM and its Engagement shall require the prior written consent of KCM. The Client shall cause and hereby represents that each of its Client Representatives to whom the KCM Information is disclosed is
          legally bound to keep such KCM Information confidential as provided by this Section 6. The Client shall be responsible for any damages to KCM to the extent caused by breaches of this Section 6 by any of its Client Representatives.

        

        

        KCM agrees to keep confidential all material nonpublic information provided to it by the Client (the “Client Information”). Notwithstanding any provision herein to the contrary, KCM
          may disclose Client Information to its affiliates, members, officers, accountants, agents, legal advisors and employees (the “Representatives”) to the extent required for the exclusive
          purpose of the Engagement. KCM shall cause and hereby represents that each of its Representatives to whom the Client Information is disclosed is legally bound to keep such Client Information confidential as provided by this Section 6. KCM shall
          be responsible for any damages to the Client to the extent caused by breaches of this Section 6 by any of its Representatives.

        

        

        KCM Information shall be considered public and not protected by this Agreement if (a) it is or becomes generally available to the public other than as a result of a disclosure by the Client or a Client Representatives in breach of the terms of
          this Section 6, (b) it becomes available to the Client on a non-confidential basis from a source (other than KCM or a Representative) not known by the Client to be under a duty of confidentiality to KCM, or (c) if it is already known to the
          Client at the time of disclosure.

        

        

        Nothing in this Agreement shall obligate either party to refrain from disclosure of KCM Information or the Client Information (as the case may be, “Confidential Information”)
          hereunder to the extent such disclosure is required by law, regulation or judicial process or at the request of a regulatory authority. In the event that any Confidential Information is required to be disclosed by law, including without
          limitation, pursuant to the terms of a subpoena or similar document or in connection with litigation or other legal proceedings (other than for routine supervisory examinations by regulatory authorities), the receiving party of such information
          hereby agrees, to the extent permitted by applicable law or regulation, to notify the disclosing party promptly of the existence, terms and circumstances surrounding such request. To the extent permitted by applicable law or regulation, the
          receiving party shall allow the disclosing party, in its sole discretion and at its sole expense, to contest the disclosure of Confidential Information on the disclosing party’s behalf, and the receiving party will reasonably cooperate with the
          disclosing party in such efforts to contest such disclosure at disclosing party’s expense.

        

        

        Each party hereto acknowledges and agrees that irreparable damage would occur to the other and their respective affiliates in the event any of the provisions of this Section 6 were not performed in accordance with their specific terms or were
          otherwise breached and monetary damages would not be a sufficient remedy for any such non-performance or breach. Accordingly, each party shall be entitled to specific performance of the terms of this Section 6, including, without limitation, an
          injunction or injunctions to prevent breaches of the provisions of this Section 6 and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction in New York, New York or the Federal District Court for the
          Southern District of New York in addition to any other remedy to which such party may be entitled at law or in equity.

      

      
        
          


      

      
        

        

        The parties hereto agree that the provisions of this Section 6 will survive the expiration or termination of this Agreement for two (2) years after such expiration or termination.

        

        

      

      
        7. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York (including, without limitation, provisions concerning limitations of actions),
          without reference to the conflicts of laws rules of that or any other jurisdiction, except that Federal law shall also apply to the extent relevant.

        

        

      

      
        To the full extent lawful, each of the Client and KCM hereby consents irrevocably to the exclusive jurisdiction of the courts of the State of New York located in the Borough of Manhattan, New York as
          having proper subject matter jurisdiction, or the Federal District Court for the Southern District of New York. Any suit involving any dispute or matter arising under this Agreement may only be brought before a judge in the courts of the State of
          New York located in the Borough of Manhattan, New York or the Federal District Court for the Southern District of New York, and each of the Client and KCM consents to the exercise of personal jurisdiction by any such court with respect to such
          proceeding.

        

        

        Each of the Client and KCM hereby irrevocably waives trial by jury.

        

        

      

      
        8. Miscellaneous.

        

        

      

      
        (a) The parties understand that KCM is being engaged hereunder as an independent contractor to provide the services described above solely to the Client. In such capacity, KCM shall act as an independent
          contractor, and any duties of KCM arising out of its engagement pursuant to this Agreement shall be contractual in nature and shall be owed solely to the Client. The Client understands and acknowledges KCM is not acting as a fiduciary of the
          Client, the security holders or creditors of the Client or any other persons in connection with the Engagement. The Client acknowledges that KCM is not providing any advice on tax, legal, regulatory or accounting matters and that the Client will
          seek the advice of its own professional advisors for such matters and make an independent decision regarding any transaction contemplated herein based upon such advice.

        

        

        (b) The Client understands and acknowledges that KCM and its affiliates (collectively, the “KCM Group”), engage in providing a wide variety of financial
          consulting services and other investment banking products and services to a wide range of institutions and individuals. In the ordinary course of business, the KCM Group and certain of its employees, as well as investment funds in which they may
          have financial interests (including advisory or sub-advisory interests) or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade or otherwise effect transactions, in debt, equity, and other securities and
          financial instruments (including bank loans and other obligations) of, or investments in, a party that may be involved in the matters contemplated by this Agreement or have other relationships with such parties. With respect to any such
          securities, financial instruments and/or investments, all rights in respect of such securities, financial instruments and investments, including any voting rights, will be exercised by the holder of the rights, in its sole discretion. In
          addition, the KCM Group may currently, and may in the future, have relationships with parties other than the Client, including parties that may have interests with respect to the Client, the Transaction or other parties involved in the
          Transaction, from which conflicting interests or duties may arise. Although the KCM Group in the course of such other activities and relationships may acquire information about the Client, the Transaction or such other parties, the KCM Group
          shall have no obligation to, and may not be contractually permitted to, disclose such information, or the fact that the KCM Group is in possession of such information, to the Client or to use such information on the Client’s behalf.

        

        

        In order to enable KCM to bring relevant resources to bear on its engagement hereunder from among its affiliates, the Client agrees that KCM may share information obtained from the Client and other parties
          hereunder with other members of the KCM Group, and may perform the services contemplated hereby in conjunction with such other members; provided, that such other members of the KCM Group agree to be bound by any applicable confidentiality
          provisions separately agreed between the parties related to the Transaction and that KCM shall be responsible for the breach by any member of the KCM Group of such confidentiality provisions.

        

        

        (c) This Agreement incorporates the entire agreement, and supersedes all prior agreements, arrangements or understandings (whether oral or written), between the parties with respect to the subject matter hereof,
          and may not be amended or modified except in writing signed by each party hereto.

        

        

        (d) This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original and all of which together will be deemed to be one and the same document.

      

      
        
          


      

      
        

        

        (e) KCM agrees that it shall have no right, title, interest or claim of any kind in or to any monies held in the trust account established in connection with the Client’s initial public offering for the benefit of
          the Client and holders of shares issued in such offering, and agrees not to seek recourse against such trust account for any reason whatsoever. Accordingly, KCM acknowledges and agrees that any indemnification payment to be provided hereunder
          will only be able to be satisfied paid by the Client if (i) if prior to an initial business combination, to the extent that the Client has sufficient funds outside of the trust account to satisfy its obligations hereunder or (ii) on or after the
          date that the Client consummates an initial business combination, and in both cases such indemnification and other payments shall accrue and become due and payable immediately upon the occurrence of either event in clauses (i) and (ii).

        

        

      

      
        If you are in agreement with the foregoing, please sign and return the attached copy of this Agreement, whereupon this Agreement shall become effective as of the date hereof.
