  RE: Securities Subscription Agreement

   

  Ladies and Gentlemen:

   

  We are pleased to accept the offer Riverview
      Sponsor Partners, LLC (the “Subscriber” or “you”) has made to purchase 5,750,000 shares of Class B common stock (the “Shares”), $0.001 par value per share (together with all other classes of Company (as defined below) common
      stock, the “Common Stock”), up to 750,000 Shares of which are subject to complete or partial forfeiture by you if the underwriters of the initial public offering (“ IPO”) of Riverview Acquisition Corp., a Delaware corporation (the “Company”),

      do not fully exercise their over-allotment option (the “Over-allotment Option”). The terms (this “Agreement”) on which the Company is willing to sell the Shares to the Subscriber, and the Company and the Subscriber’s agreements
      regarding such Shares, are as follows:

   

  	1.	Subscription and Purchase of Shares. For the sum of $25,000 (the “Purchase Price”), which the Company
            acknowledges receiving in cash, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby subscribes for and purchases the Shares from the Company, 750,000 of which are subject to forfeiture, on the terms and subject to
            the conditions set forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate registered in the Subscriber’s name representing the Shares
            (the “Original Certificate”), or effect such delivery in book entry form.

   

  		2.	Representations, Warranties and Agreements.

   

  		2.1.	Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the Subscriber
            hereby represents and warrants to the Company and agrees with the Company as follows:

   

  		2.1.1.	No Government Recommendation or Approval. The Subscriber understands that no federal or state agency has passed upon or made any
            recommendation or endorsement of the offering of the Shares.

   

  		2.1.2.	No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the transactions
            contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party, (iii) any law, statute,
            rule or regulation to which the Subscriber is subject, or (iv) any agreement, order, judgment or decree to which the Subscriber is subject.

   

  		2.1.3.	Organization and Authority. The Subscriber is a Delaware limited liability company, validly existing and in good standing under the
            laws of Delaware and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement will be a legal, valid and binding agreement of the
            Subscriber, enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights
            generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity).

   

  		2.1.4.	Experience, Financial Capability and Suitability. The Subscriber is: (i) sophisticated in financial matters and is able to evaluate the
            risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the

   

  
    1

    
        

  

   

  Shares have not been registered
      under the Securities Act (as defined below) and therefore cannot be resold unless subsequently registered under the Securities Act or an exemption from such registration is available. The Subscriber is capable of evaluating the merits and risks of
      its investment in the Company and has the capacity to protect its own interests. The Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (x) an effective registration statement under the Securities Act or
      (y) an exemption from registration available with respect to such sale. The Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of the Subscriber’s investment in the Shares.

   

  		2.1.5.	Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has had the opportunity to
            ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional information
            to verify the accuracy of all information so obtained. In determining whether to make this investment, the Subscriber has relied solely on the Subscriber’s own knowledge and understanding of the Company and its business based upon the
            Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. The Subscriber understands that no person has been authorized to give any information or to make any representations which were not furnished
            pursuant to this Section 2 and the Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations or its prospects.

   

  		2.1.6.	Regulation D Offering. The Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a) of
            Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption applicable to “accredited investors” within the
            meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under federal and state law.

   

  		2.1.7.	Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’s own account and not
            for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not enter into this Agreement as a result of any general solicitation or general advertising within the
            meaning of Rule 502 of Regulation D under the Securities Act.

   

  		2.1.8.	Restrictions on Transfer; Shell Company. The Subscriber understands the Shares are being offered in a transaction not involving a
            public offering within the meaning of the Securities Act. The Subscriber understands the Shares will be “restricted securities” as defined in Rule 144(a)(3) under the Securities Act and the Subscriber understands that the certificates or book
            entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise
            transferred only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. The Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be made, as a condition
            precedent to any such transfer, the Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Shares. The Subscriber
            further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following consummation of the initial business combination of the Company, despite
            technical compliance with the certain requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.

   

  		2.1.9.	No Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or
            appropriate on the part of the Subscriber in connection with the transactions contemplated by this Agreement.

   

  		2.2.	Company’s Representations, Warranties and Agreements . To induce the Subscriber to purchase the Shares, the Company hereby represents
            and warrants to the Subscriber and agrees with the Subscriber as follows:

   

  
    2

    
        

  

   

  		2.2.1.	Organization and Corporate Power. The Company is a Delaware corporation and is qualified to do business in every jurisdiction in which
            the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority necessary to
            carry out the transactions contemplated by this Agreement.

   

  		2.2.2.	No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the transactions
            contemplated hereby do not violate, conflict with or constitute a default under (i) the Certificate of Incorporation or Bylaws of the Company, (ii) any agreement, indenture or instrument to which the Company is a party, (iii) any law, statute,
            rule or regulation to which the Company is subject, or (iv) any agreement, order, judgment or decree to which the Company is subject.

   

  		2.2.3.	Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Shares will be duly and validly
            issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind,
            other than (a) transfer restrictions hereunder and other agreements to which the Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under federal and state securities laws, and (c) liens,
            claims or encumbrances imposed due to the actions of the Subscriber.

   

  		2.2.4.	No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company
            which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii) question the validity or legality of any transactions or seek to recover damages or to obtain other
            relief in connection with any transactions.

   

  		3.	Forfeiture of Shares.

   

  		3.1.	Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the representative of the
            underwriters of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of the Shares) shall forfeit any and all rights to such number of Shares (up to an aggregate of 750,000
            Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and all other initial stockholders prior to the IPO, if any) will own an aggregate number of
            Shares (not including shares of Common Stock issuable upon exercise of any warrants or purchased by the Subscriber in the IPO or in the aftermarket) equal to 20% of the issued and outstanding shares of Common Stock immediately following the
            IPO.

   

  		3.2.	Termination of Rights as Stockholder. If any of the Shares are forfeited in accordance with this Section 3, then after such time the
            Subscriber (or successor in interest), shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such forfeited Shares.

   

  		3.3.	Share Certificates. In the event an adjustment to the Original Certificates, if any, is required pursuant to this Section 3, then the
            Subscriber shall return such Original Certificates to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising Subscriber of such adjustment, following which a new certificate (the “New
              Certificate”), if any, shall be issued in such amount representing the adjusted number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the Subscriber as soon as practicable. Any such adjustment for any
            uncertificated securities held by the Subscriber shall be made in book-entry form.

   

  	4.	Waiver of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased pursuant to this Agreement, the
            Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public stockholders and into which
            substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial

   

  
    3

    
        

  

   

  business combination. For purposes of clarity, in
      the event the Subscriber purchases any shares of Common Stock in the IPO or in the aftermarket, any additional shares of Common Stock so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will
      the Subscriber have the right to redeem any Shares for funds held in the Trust Account upon the successful completion of an initial business combination by the Company.

   

  		5.	Restrictions on Transfer.

   

  		5.1.	Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as an “Insider

              Letter”) to be dated as of the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares unless, prior thereto (a) a
            registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or (b) the Company has received an opinion from counsel
            reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and Exchange Commission thereunder and with
            all applicable state securities laws.

   

  		5.2.	Lock-up. Subscriber acknowledges that the Securities will be subject to lock-up provisions contained in the Insider Letter.

   

  		5.3.	Restrictive Legends. All certificates representing the Shares shall have endorsed thereon legends substantially as follows:

   

  “THE SECURITIES REPRESENTED
      HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
      EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.”

   

  “THE SECURITIES REPRESENTED BY

  		6.3.	Entire Agreement. This Agreement, together with the Insider Letter and the Registration Rights Agreement, each substantially in the
            form to be filed as an exhibit to the registration statement on Form S-1 associated with the Company’s IPO, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject matter hereof and
            supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be
            used to interpret, change or restrict, the express terms and provisions of this Agreement.

   

  		6.4.	Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed
            by all parties hereto.

   

  		6.5.	Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only by
            written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this
            Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent.

   

  		6.6.	Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written consent of the other party.

   

  		6.7.	Benefit. All statements, representations, warranties, covenants and agreements in this Agreement shall be binding on the parties hereto
            and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties hereto, and no person or entity
            shall be regarded as a third-party beneficiary of this Agreement.

   

  		6.8.	Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and
            governed by the laws of the State of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof .

   

  		6.9.	Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof,
            contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain in full force and
            effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect.

   

  		6.10.	No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under this
            Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, nor
            any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any
            remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or
            demand to any other or further notice or demand in similar or other circumstances or constitute a

   

  
    5

    
        

  

   

  waiver of the rights of the party giving such
      notice or demand to any other or further action in any circumstances without such notice or demand.

   

  		6.11.	Survival of Representations and Warranties. All representations and warranties made by the parties hereto in this Agreement or in any
            other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties.

   

  		6.12.	No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
            consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and hold the other harmless from
            any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending
            against any such claim.

   

  		6.13.	Headings and Captions. The headings and captions of the various sections of this Agreement are for convenience of reference only and
            shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof.

   

  		6.14.	Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and
            the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
            delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if
            such signature page were an original thereof.

   

  		6.15.	Construction. The words “include,” “includes,” and “including” will be deemed to be followed by “without
              limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires.
            The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular section unless expressly so limited. The parties
            hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there
            exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party
            hereto is in breach of the first representation, warranty, or covenant.

   

  		6.16.	Mutual Drafting. This Agreement is the joint product of the Subscriber and the Company and each provision hereof has been subject to
            the mutual consultation, negotiation and agreement of such parties and shall n ot be construed for or against any party hereto.

   

  	7.	Voting and Redemption of Shares. The Subscriber agrees to vote the Shares in favor of an initial business combination that the Company
            negotiates and submits for approval to the Company’s stockholders and shall not seek redemption with respect to such Shares. Additionally, the Subscriber agrees not to redeem any Shares in connection with a redemption or tender offer presented
            to the Company’s stockholders in connection with an initial business combination negotiated by the Company.
