    WARRANT AGREEMENT

    

    

    between

    

    

    FORTISTAR SUSTAINABLE SOLUTIONS CORP.

    

    

    and

    

    

    CONTINENTAL STOCK TRANSFER & TRUST COMPANY

    

    

    THIS WARRANT AGREEMENT (this “Agreement”), dated as of January 29, 2021, is by and between Fortistar Sustainable Solutions Corp., a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”, also
      referred to herein as the “Transfer Agent”).

    

    

    WHEREAS, on January 26, 2021, the Company entered into that certain Private Placement Warrants Purchase Agreement with FSSC Sponsor LLC, a Delaware limited liability company (the “Sponsor”), pursuant to which the Sponsor will purchase an aggregate of 6,500,000 redeemable warrants (or up to 7,175,000 warrants if the Over-allotment Option (as defined below) in connection with the Company’s Offering
      (as defined below) is exercised in full) simultaneously with the closing of the Offering bearing the legend set forth in Exhibit B hereto (the “Private Placement Warrants”) at a
      purchase price of $1.00 per Private Placement Warrant; and

    

    

    WHEREAS, in order to finance the Company’s transaction costs in connection with an intended initial Business Combination (as defined below), the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers
      and directors may, but are not obligated to, loan the Company funds as the Company may require, of which up to $1,000,000 may be convertible into up to an additional 1,000,000 Private Placement Warrants of the post Business Combination entity at a
      price of $1.00 per warrant; and

    

    

    WHEREAS, the Company is engaged in an initial public offering (the “Offering”) of units of the Company’s equity securities, each such unit comprised of one
      share of Common Stock (as defined below) and one-half of one Public Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and deliver up to
      11,250,000 redeemable warrants (including up to 12,937,500 redeemable warrants subject to the Over-allotment Option) to public investors in the Offering (the “Public Warrants” and, together
      with the Private Placement Warrants, the “Warrants”). Each whole Warrant entitles the holder thereof to purchase one share of Class A common stock of the Company, par value $0.0001 per share
      (“Common Stock”), for $11.50 per share, subject to adjustment as described herein; and

    

    

    WHEREAS, the Company has filed with the Securities and Exchange Commission (the “Commission”) registration statements on Form S-1, Nos. 333-251922 and
      333-252446 (the “Registration Statement”) and prospectus (the “Prospectus”), for the registration, under the Securities Act of
      1933, as amended (the “Securities Act”), of the Units, the Public Warrants and the shares of Common Stock included in the Units; and

    

    

    WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of
      the Warrants; and

    

    

    WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the
      Company, the Warrant Agent, and the holders of the Warrants; and

    

    

    WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent (if a physical certificate
      is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

    
      
        

    

    
    

    

    NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

    

    

    1.          Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform
      the same in accordance with the terms and conditions set forth in this Agreement.

    

    

    2.          Warrants.

    

    

    2.1          Form of Warrant. Each Warrant shall initially be issued in registered form only.

    

    

    2.2          Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not
      be exercised by the holder thereof.

    

    

    2.3          Registration.

    

    

    2.3.1          Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of original issuance and the
      registration of transfer of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with
      instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have
      accounts with (i) The Depository Trust Company (the “Depositary”) (such institution, with respect to a Warrant in its account, a “Participant”)
      or (ii) the Depositary or its nominee for each book-entry Warrant Certificate.

    

    

    If the Depositary subsequently ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry
      settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the
      Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such Warrants which shall be in the form annexed hereto
      as Exhibit A.

    

    

    Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer, Chief Financial Officer, Secretary or other principal officer of the
      Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if
      he or she had not ceased to be such at the date of issuance.

    

    

    2.3.2          Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant is registered in
      the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on
      any physical certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

    
      2

      
        

    

    

    

    2.4          Detachability of Warrants. The Common Stock and Public Warrants comprising the Units shall begin separate trading on the 52nd day following the date of the Prospectus or, if such 52nd day is not on a
      day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business (a “Business Day”), then on the immediately succeeding Business
      Day following such date, or earlier (the “Detachment Date”) with the consent of Credit Suisse Securities (USA) LLC and BofA Securities, Inc., as representatives of the several underwriters,
      but in no event shall the Common Stock and the Public Warrants comprising the Units be separately traded until (A) the Company has filed a Current Report on Form 8-K with the Commission containing an audited balance sheet reflecting the receipt by
      the Company of the gross proceeds of the Offering, including the proceeds received by the Company from the exercise by the underwriters of their right to purchase additional Units in the Offering (the “Over-allotment Option”), if the Over-allotment Option is exercised prior to the filing of the Form 8-K, and (B) the Company issues a press release and files with the Commission a current report on Form 8-K announcing when such
      separate trading shall begin.

    

    

    2.5          No Fractional Warrants Other Than as Part of Units. The Company shall not issue fractional Warrants other than as part of Units, each of which is comprised of one share of Common Stock and one-half of
      one Public Warrant. If, upon the detachment of Public Warrants from Units or otherwise, a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the nearest whole number the number of Warrants to be
      issued to such holder.

    

    

    2.6          Private Placement Warrants. The Private Placement Warrants shall be identical to the Public Warrants, except that so long as they are held by the Sponsor or any of its Permitted Transferees (as
      defined below) the Private Placement Warrants: (i) may be exercised for cash or on a cashless basis, pursuant to subsection 3.3.1(c) hereof, (ii) may not be (including the shares of Common Stock issuable upon exercise of the Private Placement
      Warrants) transferred, assigned or sold until thirty (30) days after the completion by the Company of an initial Business Combination (as defined below), and (iii) shall not be redeemable by the Company pursuant to Section 6.1 hereof; provided,
      however, that in the case of (ii), the Private Placement Warrants and any shares of Common Stock held by the Sponsor or any of its Permitted Transferees issued upon exercise of the Private Placement Warrants may be transferred by the holders
      thereof:

    

    

    (a)          to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Sponsor, or any affiliates of the Sponsor;

    

    

    (b)          in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family; an affiliate of such person,
      or to a charitable organization;

    

    

    (c)          in the case of an individual, by virtue of the laws of descent and distribution upon death of the individual;

    

    

    (d)          in the case of an individual, pursuant to a qualified domestic relations order;

    

    

    (e)          by private sales or transfers made in connection with the consummation of the Company’s initial Business Combination at prices no greater than the price at which the Warrants were originally purchased;

    

    

    (f)          in the event of the Company’s liquidation prior to the completion of its initial Business Combination; or

    

    

    (g)          by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; or

    

    

    (h)          in the event of the Company’s completion of a liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in all of the Company’s stockholders having the right to
      exchange their shares of Common Stock for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination;

    

    

    provided, however, that in the case of clauses (a) through (e), these permitted transferees (the “Permitted Transferees”) must enter into a written agreement with the
      Company agreeing to be bound by these transfer restrictions.

    3.          Terms and Exercise of Warrants.

    

    

    3.1          Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent (if a physical certificate is issued), entitle the Registered Holder thereof, subject to the provisions of such Warrant and
      of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1.
      The term “Warrant Price” as used in this Agreement shall mean the price per share at which shares of Common Stock may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to
      the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days, provided, that the Company shall provide at least twenty (20) days prior written notice of such reduction to Registered Holders of the Warrants and,
      provided further that any such reduction shall be identical among all of the Warrants.

    

    

    3.2          Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing on the later of: (i) the date
      that is thirty (30) days after the first date on which the Company completes a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company and one or more businesses (a “Business Combination”), and (ii) the date that is twelve (12) months from the date of the closing of the Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of:
      (x) the date that is five (5) years after the date on which the Company completes its initial Business Combination, (y) the liquidation of the Company in accordance with the Company’s amended and restated certificate of incorporation, as amended from
      time to time, if the Company fails to consummate a Business Combination, and (z) other than with respect to the Private Placement Warrants then held by the Sponsor or any Permitted Transferees with respect to a redemption pursuant to Section 6.1
      hereof, the Redemption Date (as defined below) as provided in Section 6.3 hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be
      subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below with respect to an effective registration statement. Except with respect to the right to receive the Redemption Price (as defined below) (other
      than with respect to a Private Placement Warrant then held by the Sponsor or any Permitted Transferees with respect to a redemption pursuant to Section 6.1 hereof) in the event of a redemption (as set forth in Section 6 hereof), each
      Warrant (other than a Private Placement Warrant then held by the Sponsor or any Permitted Transferees with respect to a redemption pursuant to Section 6.1 hereof) not exercised on or before the Expiration Date shall become void, and all
      rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided,
      that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

    

    

    3.3          Exercise of Warrants.

    

    

    3.3.1          Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent (if in the form of a physical certificate), may be exercised by the
      Registered Holder thereof by delivering to the Warrant Agent at its corporate trust department (i) the definitive warrant certificate evidencing the Warrants to be exercised, or, in the case of a Warrant represented by a book-entry, the Warrants to
      be exercised (the “Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such
      purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to purchase any shares of Common Stock pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of
      the definitive warrant certificate or, in the case of a Book-Entry Warrant, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) the payment in full of the Warrant Price for each full share of Common Stock
      as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock and the issuance of such shares of Common Stock, as follows:

    

    

    (a)          in lawful money of the United States, in good certified check or good bank draft payable to the Warrant Agent;

    
      4

      
        

    

    

    

    (b)          in the event of a redemption pursuant to Section 6.1 hereof in which the Company’s board of directors (the “Board”) has elected to require
      all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock
      underlying the Warrants, multiplied by the excess of the “Fair Market Value,” as defined in this subsection 3.3.1(b), over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(b), Section
        6.1 and Section 6.4, the “Fair Market Value” shall mean the average last reported sale price of the shares of Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice of redemption
      is sent to the holders of the Warrants, pursuant to Section 6 hereof;

    

    

    (c)          with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a Permitted Transferee, by surrendering the Warrants for that number of shares of Common
      Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the excess of the “Fair Market Value”, as defined in this subsection 3.3.1(c), over the Warrant
      Price by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the average last reported sale price of the shares of Common Stock for the ten (10) trading days ending on the third
      trading day prior to the date on which notice of exercise of the Warrant is sent to the Warrant Agent;

    

    

    (d)          as provided for in Section 6.2 with respect to a Make-Whole Exercise; or

    

    

    (e)          as provided in Section 7.4 hereof.

    

    

    3.3.2          Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is pursuant to subsection
        3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares of Common Stock to which he, she or it is entitled, registered in such name or names
      as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares of Common Stock as to which such Warrant shall not have been
      exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement
      under the Securities Act covering the issuance of the shares of Common Stock issuable upon the exercise of the Public Warrants is then effective and a current prospectus relating thereto is available, subject to the Company’s satisfying its
      obligations under Section 7.4, or a valid exemption from registration is available. No Warrant shall be exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the shares of Common
      Stock issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the Registered Holder of the Warrants. The Company may require holders of Public Warrants to settle
      the Warrant on a “cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants on a “cashless basis,” the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a
      share of Common Stock, the Company shall round down to the nearest whole number, the number of shares of Common Stock to be issued to such holder.

    

    

    3.3.3          Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and non-assessable.

    

    

    3.3.4          Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of
      record of such shares of Common Stock on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case
      of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of
      such shares of Common Stock at the close of business on the next succeeding date on which the share transfer books or book-entry system are open.

    
      5

      
        

    

    

    

    3.3.5          Maximum Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no
      holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not
      have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (or such other
      amount as such holder may specify) (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing
      sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of the Warrant with respect to which the determination of such
      sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the
      unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation
      on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities
      Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of outstanding shares of Common Stock, the holder may rely on the number of
      outstanding shares of Common Stock as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent
      public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of the holder of the Warrant, the
      Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to
      the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the holder of a Warrant may
      from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st)
      day after such notice is delivered to the Company.

    

    

    4.          Adjustments.

    

    

    4.1          Stock Dividends.

    

    

    4.1.1          Split-Ups. If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares
      of Common Stock to all or substantially all holders of Common Stock, or by a split-up of shares of Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common
      Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in the outstanding shares of Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock at a price
      less than the “Fair Market Value” (as defined below) shall be deemed a stock dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any
      other equity securities sold in such rights offering that are convertible into or exercisable for the Common Stock) multiplied by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y)
      the Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Common Stock, in determining the price payable for Common Stock, there shall be taken into account
      any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Fair Market Value” means the volume weighted average price of the Common Stock as reported during the ten (10) trading day
      period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

    
      6

      
        

    

    

    

    4.1.2          Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to all or
      substantially all holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b)
      Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the holders of the Common Stock in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of Common Stock in
      connection with a stockholder vote to amend the Company’s amended and restated certificate of incorporation to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business
      Combination or to redeem 100% of the shares of Common Stock included in the Units sold in the Offering (the “Public Shares”) if the Company does not complete the initial Business Combination
      within the time period set forth in the Company’s amended and restated certificate of incorporation or with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity or (e) in connection with the
      redemption of the Public Shares upon the failure of the Company to complete its initial Business Combination and any subsequent distribution of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market
      value (as determined by the Board, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock
      during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash
      distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) to the extent it does not exceed $0.50 (being 5% of the offering price of the Units in the Offering).

    

    

    4.2          Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of outstanding shares of Common Stock is decreased by a consolidation,
      combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of
      Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

    

    

    4.3          Adjustments in Exercise Price.

    

    

    4.3.1          Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be
      adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately
      prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

    

    

    4.3.2          If the Company issues additional shares of Common Stock or securities convertible into or exercisable or exchangeable for shares of Common Stock for capital raising purposes in connection with the closing
      of its initial Business Combination at an issue price or effective issue price of less than $9.20 per share of Common Stock, with such issue price or effective issue price to be determined in good faith by the Board (and in the case of any such
      issuance to the initial stockholders (as defined in the Prospectus) or their affiliates, without taking into account any founder shares held by such stockholders or their affiliates, as applicable, prior to such issuance) (the “New Issuance Price”), the Warrant Price shall be adjusted (to the nearest cent) to be equal to 115% of the New Issuance Price.

    4.4          Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change under subsections 4.1.1 or
      4.1.2 or Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in
      which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or
      other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and
      conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other
      securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had
      exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance” ); provided, however, that (i) if the holders of the Common Stock were
      entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for
      which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if a
      tender, exchange or redemption offer shall have been made to and accepted by the holders of the Common Stock (other than a tender, exchange or redemption offer made by the Company in connection with redemption rights held by stockholders of the
      Company as provided for in the Company’s amended and restated certificate of incorporation or bylaws or as a result of the redemption of shares of Common Stock by the Company if a proposed initial Business Combination is presented to the stockholders
      of the Company for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor rule))
      of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act (or any successor rule)) and any members of any such group of which any such affiliate or associate is
      a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act (or any successor rule)) more than 50% of the outstanding shares of Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the
      highest amount of cash, securities or other property to which such holder would actually have been entitled as a stockholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such
      offer and all of the shares of Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible
      to the adjustments provided for in this Section 4; provided, further, that if less than 70% of the consideration receivable by the holders of the Common Stock in the applicable event is payable in the form of capital stock or
      shares in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered
      Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be
      reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant
      Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant
      Model for a Capped American Call on Bloomberg Financial Markets (“Bloomberg”). For purposes of calculating such amount, (1) Section 6 of this Agreement shall be taken into account,
      (2) the price of each share of Common Stock shall be the volume weighted average price of the shares of Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (3)
      the assumed volatility shall be the 90 day volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event, and (4) the assumed risk-free interest rate
      shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the shares of
      Common Stock consists exclusively of cash, the amount of such cash per share of Common Stock, and (ii) in all other cases, the volume weighted average price of the shares of Common Stock as reported during the ten (10) trading day period ending on
      the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in shares of Common Stock covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection
        4.1.1 or Sections 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In
      no event will the Warrant Price be reduced to less than the par value per share issuable upon exercise of the Warrant.

    
      8

      
        

    

    

    

    4.5          Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to
      the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares of Common Stock purchasable at such price upon the exercise of a Warrant, setting forth in
      reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company shall give written notice of the
      occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect
      the legality or validity of such event.

    

    

    4.6          No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares of Common Stock upon the exercise of Warrants. If, by
      reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the
      nearest whole number the number of shares of Common Stock to be issued to such holder.

    

    

    4.7          Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and
      the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that
      the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

    

    

    4.8          Other Events. In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections of this Section 4 are strictly applicable, but which would require
      an adjustment to the terms of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent public
      accountants, investment banking or other appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of
      this Section 4 and, if they determine that an adjustment is necessary, the terms of such adjustment. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion.

    

    

    5.          Transfer and Exchange of Warrants.

    

    

    5.1          Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, and, if
      in the form of a physical certificate, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be
      issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

    

    

    5.2          Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange
      therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer
      bears a restrictive legend (as in the case of the Private Placement Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company
      stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.

    

    

    5.3          Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a
      fraction of a warrant, except as part of the Units.

    

    

    5.4          Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

    
      9

      
        

    

    

    

    5.5          Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued
      pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

    

    

    5.6          Transfer of Warrants. Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together with the Unit in which such Warrant is included, and only for the purpose of
      effecting, or in conjunction with, a transfer or exchange of such Unit. Furthermore, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included in such Unit. Notwithstanding the foregoing, the
      provisions of this Section 5.6 shall have no effect on any transfer of Warrants on and after the Detachment Date.

    

    

    6.          Redemption.

    

    

    6.1          Redemption of Warrants for Cash. Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time while they are
      exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at the price of $0.01 per Warrant (the “Redemption Price”), provided that the last reported sales price of the Common Stock has been at least $18.00 per share (subject to adjustment in
      compliance with Section 4 hereof), on each of twenty (20) trading days within the thirty (30) trading-day period ending on the third Business Day prior to the date on which notice of the redemption is given and provided that there is an
      effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3 below) or the
      Company has elected to require the exercise of the Warrants on a “cashless basis” pursuant to subsection 3.3.1.

    

    

    6.2          Redemption of Warrants for $0.10 or for Shares of Common Stock. Subject to Section 6.5 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company,
      commencing ninety (90) days after they are first exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at a Redemption Price of
      $0.10 per Warrant, provided that the last reported sales price of the Common Stock reported has been at least $10.00 per share (subject to adjustment in compliance with Section 4 hereof), on the trading day prior to the date on which notice
      of the redemption is given, the Private Placement Warrants are also concurrently exchanged at the same price (equal to a number of shares of Common Stock) as the outstanding Public Warrants and there is an effective registration statement covering
      the Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.3 below). During the Redemption Period in connection with a
      redemption pursuant to this Section 6.2, Registered Holders of the Warrants may elect to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1 and receive a number of shares of Common Stock determined by reference
      to the table below, based on the Redemption Date (calculated for purposes of the table as the period to expiration of the Warrants) and the “Fair Market Value” (as such term is defined in subsection 3.3.1(b)) (a “Make-Whole Exercise”).

    The exact Fair Market Value and Redemption Date (as defined below) may not be set forth in the table above, in which case, if the Fair Market Value is between two values in the table or the Redemption Date is between two
      redemption dates in the table, the number of shares of Common Stock to be issued for each Warrant exercised in a Make-Whole Exercise will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower
      Fair Market Values and the earlier and later redemption dates, as applicable, based on a 365- or 366-day year, as applicable.

    

    

    The stock prices set forth in the column headings of the table above shall be adjusted as of any date on which the number of shares issuable upon exercise of a Warrant is adjusted pursuant to Section 4. The
      adjusted stock prices in the column headings shall equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the number of shares deliverable upon exercise of a Warrant immediately prior to such
      adjustment and the denominator of which is the number of shares deliverable upon exercise of a Warrant as so adjusted. The number of shares in the table above shall be adjusted in the same manner and at the same time as the number of shares issuable
      upon exercise of a Warrant. In no event will the number of shares issued in connection with a Make-Whole Exercise exceed 0.361 shares of Common Stock per Warrant (subject to adjustment).

    

    

    6.3          Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants pursuant to Section 6.1 or Section 6.2, the Company shall fix a date for
      the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date
      (the “30-day Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the
      manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice.

    

    

    6.4          Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with subsection 3.3.1(b) or Section 6.2 of this Agreement) at any
      time after notice of redemption shall have been given by the Company pursuant to Section 6.3 hereof and prior to the Redemption Date. In the event that the Company determines to require all holders of Warrants to exercise their Warrants on a
      “cashless basis” pursuant to subsection 3.3.1, the notice of redemption shall contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants, including the “Fair Market Value”
      (as such term is defined in subsection 3.3.1(b) hereof) in such case. On and after the Redemption Date the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

    

    

    6.5          Exclusion of Private Placement Warrants. The Company agrees that the redemption rights provided in Section 6.1 shall not apply to the Private Placement Warrants if at the time of the
      redemption such Private Placement Warrants continue to be held by the Sponsor or its Permitted Transferees. However, once such Private Placement Warrants are transferred (other than to Permitted Transferees under Section 2.6), the
      Company may redeem the Private Placement Warrants pursuant to Section 6.1 hereof as well, provided that the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants to exercise the Private
      Placement Warrants prior to redemption pursuant to Section 6.4. Private Placement Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become
      Public Warrants under this Agreement.

    7.          Other Provisions Relating to Rights of Holders of Warrants.

    

    

    7.1          No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends,
      or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter.

    

    

    7.2          Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in
      their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall
      constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

    

    

    7.3          Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in
      full of all outstanding Warrants issued pursuant to this Agreement.

    

    

    7.4          Registration of Common Stock; Cashless Exercise at Company’s Option.

    

    

    7.4.1          Registration of the Common Stock. The Company agrees that as soon as practicable, but in no event later than fifteen (15) Business Days after the closing of its initial Business Combination, it
      shall use its best efforts to file with the Commission, and within sixty (60) Business Days following the closing of its initial Business Combination have declared effective, a registration statement for the registration, under the Securities Act, of
      the shares of Common Stock issuable upon exercise of the Warrants. The Company shall use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating
      thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the 60th Business Day following the closing of the Business Combination, holders
      of the Warrants shall have the right, during the period beginning on the 61st Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and during any other
      period when the Company shall fail to have maintained an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in
      accordance with Section 3(a)(9) of the Securities Act (or any successor rule) or another exemption) for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock
      underlying the Warrants, multiplied by the excess of the “Fair Market Value” (as defined below) over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the average last
      reported sale price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker
      or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Public Warrant, the Company shall, upon request,
      provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1
      is not required to be registered under the Securities Act and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in
      Rule 144 under the Securities Act (or any successor rule)) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of
      the Warrants have been exercised, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

    
      12

      
        

    

    

    

    7.4.2          Cashless Exercise at Company’s Option. If the Common Stock is at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a
      “covered security” under Section 18(b)(1) of the Securities Act (or any successor rule), the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in
      accordance with Section 3(a)(9) of the Securities Act (or any successor rule) as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration
      statement for the registration, under the Securities Act, of the shares of Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its best efforts to register or qualify the shares
      of Common Stock issuable upon exercise of the Public Warrant under the blue sky laws of the state of residence of the exercising Public Warrant holder to the extent an exemption is not available.

    

    

    8.          Concerning the Warrant Agent and Other Matters.

    

    

    8.1          Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of
      Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common Stock.

    

    

    8.2          Resignation, Consolidation, or Merger of Warrant Agent.

    

    

    8.2.1          Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder
      after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant
      Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice,
      submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor
      Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of
      New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers,
      rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the
      predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any
      successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights,
      immunities, duties, and obligations.

    

    

    8.2.2          Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the
      Common Stock not later than the effective date of any such appointment.

    

    

    8.2.3          Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or
      consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

    

    

    8.3          Fees and Expenses of Warrant Agent.

    

    

    8.3.1          Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall, pursuant to its obligations under this Agreement,
      reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

    
      13

      
        

    

    

    

    8.3.2          Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged, and delivered all such further and other acts, instruments,
      and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

    

    

    8.4          Liability of Warrant Agent.

    

    

    8.4.1          Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or
      established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement
      signed by the Chief Executive Officer, Chief Financial Officer, Secretary or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it
      pursuant to the provisions of this Agreement.

    

    

    8.4.2          Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless
      against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful
      misconduct or bad faith.

      be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction. The Company hereby waives any objection to such jurisdiction and
      that such courts represent an inconvenient forum. Notwithstanding the foregoing, the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal
      district courts of the United States of America are the sole and exclusive forum.

    

    

    9.4          Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person or corporation other than the parties hereto and the Registered Holders
      of the Warrants any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Agreement

    9.6          Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such
      counterparts shall together constitute but one and the same instrument.

    

    

    9.7          Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the interpretation thereof.

    

    

    9.8          Amendments. This Agreement may be amended by the parties hereto without the consent of any Registered Holder for the purpose of curing any ambiguity, or curing, correcting or supplementing any
      defective provision contained herein or adding or changing any other provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the
      interest of the Registered Holders. All other modifications or amendments, including any amendment to increase the Warrant Price or shorten the Exercise Period and any amendment to the terms of only the Private Placement Warrants, shall require the
      vote or written consent of the Registered Holders of 50% of the then outstanding Public Warrants. Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Sections 3.1
      and 3.2, respectively, without the consent of the Registered Holders.

    

    

    9.9          Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of

    Warrant Certificate

    

    

    This Warrant Certificate certifies that                                   , or registered assigns, is the registered holder of                  warrant(s)
      evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase shares of Class A common stock, $0.0001 par value per share (“Common Stock”), of Fortistar Sustainable Solutions Corp., a Delaware corporation (the “Company”).  Each Warrant entitles the holder,
      upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided
      for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and
      in the Warrant Agreement.  Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

    

    

    Each whole Warrant is initially exercisable for one fully paid and non-assessable share of Common Stock.  The number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the
      occurrence of certain events set forth in the Warrant Agreement.

    

    

    The initial Exercise Price per share of Common Stock for any Warrant is equal to $11.50 per share. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share of Common
      Stock, the Company will round down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. The Exercise Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant
      Agreement.

    

    

    Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become
      void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.

    

    

    Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this
      place.

    

    

    This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.

    This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

    Form of Warrant Certificate

    

    

    [Reverse]

    

    

    The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to be issued pursuant to a Warrant
      Agreement dated as of [●], 2021 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant
      agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights,
      limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder) of the Warrants.  A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company.  Defined terms used in this Warrant Certificate
      but not defined herein shall have the meanings given to them in the Warrant Agreement.

    

    

    Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement.  The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant
      Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant
      Agreement) at the principal corporate trust office of the Warrant Agent.  In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall
      be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

    

    

    Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the shares of Common Stock to be issued
      upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of Common Stock is current, except through “cashless exercise” as provided for in the Warrant Agreement.

    

    

    The Warrant Agreement provides that upon the occurrence of certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be
      adjusted.  If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be
      issued to the holder of the Warrant.

    

    

    Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be
      exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of
      Warrants.

    

    

    Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like
      number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection
      therewith.

    

    

    The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by
      anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this
      Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.

    Election to Purchase

    

    

    (To Be Executed Upon Exercise of Warrant)

    

    

    The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, to receive            shares of Common Stock and herewith tenders payment for such shares of Common Stock to the
      order of Fortistar Sustainable Solutions Corp. (the “Company”) in the amount of $           in accordance with the terms hereof.  The undersigned requests that a certificate for such shares of Common Stock be
      registered in the name of      , whose address is            and that such shares of Common Stock be delivered to                   whose address is                .  If said number of shares of Common Stock is less than all of the shares of Common
      Stock purchasable hereunder, the undersigned requests that a new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of                , whose address is                    and that such
      Warrant Certificate be delivered to                , whose address is                .

    

    

    In the event that the Warrant has been called for redemption by the Company pursuant to Section 6 of the Warrant Agreement and the Company has required cashless exercise pursuant to Section 6.4 of the
      Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(b) and Section 6.4 of the Warrant Agreement.

    

    

    In the event that the Warrant has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement and a holder thereof elects to exercise its Warrant pursuant to a Make-Whole Exercise,
      the number of shares of Common Stock that this Warrant is exercisable for shall be determined in accordance with Section 6.2 of the Warrant Agreement.

    

    

    In the event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of shares of Common Stock that this
      Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) of the Warrant Agreement.

    

    

    In the event that the Warrant is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be
      determined in accordance with Section 7.4 of the Warrant Agreement.

    

    

    In the event that the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of shares of Common Stock that this Warrant is exercisable for would be determined
      in accordance with the relevant section of the Warrant Agreement which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise the right, represented by this
      Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive shares of Common Stock.  If said number of shares is less than all of the shares of Common Stock purchasable hereunder (after giving effect to the
      cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of                , whose address is                    and that such Warrant
      Certificate be delivered to                , whose address is                .

    WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $7,875,000, or $9,056,250 if the Underwriters’ over-allotment option is exercised in full, is attributable to deferred underwriting
      discounts and commissions that may be payable by the Company to the Underwriters upon the consummation of the Business Combination (as defined below) (the “Deferred Discount”); and

    

    

    WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property.

    

    

    NOW THEREFORE, IT IS AGREED:

    

    

    1.          Agreements and Covenants of Trustee.  The Trustee hereby agrees and covenants to:

    

    

    (a)          Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the Trustee at a branch office of J.P. Morgan Chase Bank, N.A. located in
      the United States and at a brokerage institution selected by the Trustee that is reasonably satisfactory to the Company;

    
      
        

    

    

    

    (b)          Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein;

    

    

    (c)          In a timely manner, upon the written instruction of the Company, invest and reinvest the Property in United States government securities within the meaning of Section 2(a)(16) of the Investment Company Act
      of 1940, as amended (the “Investment Company Act”), having a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of
      Rule 2a-7 promulgated under the Investment Company Act (or any successor rule), which invest only in direct U.S. government treasury obligations, as determined by the Company; the Trustee may not invest in any other securities or assets, it being
      understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder and the Trustee may earn bank credits or other consideration during such periods;

    

    

    (d)          Collect and receive, when due, all principal, interest or other income arising from the Property, which shall become part of the “Property,” as such term is used herein;

    

    

    (e)          Promptly notify the Company and the Representatives of all communications received by the Trustee with respect to any Property requiring action by the Company;

    

    

    (f)          Supply any necessary information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the
      Trust Account or in connection with the preparation or completion of the audit of the Company’s financial statements by the Company’s auditors;

    

    

    (g)          Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so;

    

    

    (h)          Render to the Company monthly written statements of the activities of, and amounts in, the Trust Account reflecting all receipts and disbursements of the Trust Account;

    

    

    (i)          Commence liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable, signed on behalf of the Company by its Chief Executive Officer, President, Chief Financial
      Officer, Secretary or Chairman of the Board of Directors of the Company (the “Board”) or other authorized officer of the Company, and complete the liquidation of the Trust Account and
      distribute the Property in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, including franchise and income taxes (less up to $100,000 of interest that may
      be released to the Company to pay dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein; or (y) the date which is 24 months after the closing of the Offering, if a Termination Letter has not
      been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including
      interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses) shall be distributed to the Public
      Stockholders of record as of such date;

    
      
        

    

    

    

    (j)          Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any tax obligation owed by the Company as a result
      of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward such payment to the
      relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be designated by
      the Company in writing to make such distribution, so long as there is no reduction in the principal amount initially deposited in the Trust Account; provided, further, that if the tax to be paid is a franchise tax, the written request
      by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill from the State of Delaware for the Company and a written statement from the principal financial officer of the Company setting forth the actual amount
      payable (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The written request of the Company referenced above shall constitute presumptive evidence
      that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request;

    

    

    (k)          Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from Public Stockholders properly submitted in
      connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation (A) that would modify the substance or timing of the Company’s obligation to allow redemption in connection with the
      Company’s initial Business Combination or to redeem 100% of its public shares of Common Stock if the Company has not consummated an initial Business Combination within such time as is described in the Company’s amended and restated certificate of
      incorporation or (B) with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity. The written request of the Company referenced above shall constitute presumptive evidence that the Company is
      entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and

    

    

    (l)          Not make any withdrawals or distributions from the Trust Account other than pursuant to Sections 1(i), 1(j) or 1(k) above.

    
      
        

    

    

    

    2.          Agreements and Covenants of the Company.  The Company hereby agrees and covenants to:

    

    

    (a)          Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer or Secretary. In addition, except with
      respect to its duties under Sections 1(i), 1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or telephonic advice or instruction which it, in good faith and with
      reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in writing;

    

    

    (b)          Subject to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all documented expenses, including reasonable outside counsel fees and disbursements, or
      losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any
      way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct.
      Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company
      in writing of such claim (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided
      that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the
      Company, which such consent shall not be unreasonably withheld. The Company may participate in such action with its own counsel;

    

    

    (c)          Pay the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual administration fee, and transaction processing fee which fees shall be subject to modification by
      the parties from time to time. It is expressly understood that the Property shall not be used to pay such fees unless and until it is distributed to, or on behalf of, the Company pursuant to Sections 1(i) through 1(k) hereof. The
      Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this Section 2(c), Schedule A and as may be provided in Section 2(b) hereof;

    

    

    (d)          In connection with any vote of the Company’s stockholders regarding a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination involving the Company
      and one or more businesses (the “Business Combination”), provide to the Trustee an affidavit or certificate of the inspector of elections for the stockholder meeting verifying the vote of
      such stockholders regarding such Business Combination;

    

    

    (e)          Provide the Representatives with a copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect to any proposed withdrawal from the Trust Account promptly after
      it issues the same;

    
      
        

    

    

    

    (f)          Instruct the Trustee to make only those distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under this Agreement;

    

    

    (g)          Within four (4) business days after the Underwriters exercise the over-allotment option (or any unexercised portion thereof) or such over-allotment option expires, provide the Trustee with a notice in
      writing of the total amount of the Deferred Discount, which shall in no event be less than $7,875,000 (or $9,056,250 if the Underwriters’ over-allotment option is exercised in full); and

    

    

    (h)          Expressly provide in any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination Letter in the Form of Exhibit A that the Deferred Discount be paid directly to
      the account or accounts directed by the applicable Underwriters.

    

    

    3.          Limitations of Liability. The Trustee shall have no responsibility or liability to:

    

    

    (a)          Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this Agreement and that which is expressly set forth herein;

    

    

    (b)          Take any action with respect to the Property, other than as directed in Section 1 hereof, and the Trustee shall have no liability to any party under this Agreement except for liability arising out of
      the Trustee’s gross negligence, fraud or willful misconduct;

    

    

    (c)          Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of any kind with respect to, any of the Property unless and until it
      shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses incident thereto;

    

    

    (d)          Refund any depreciation in principal of any Property;

    

    

    (e)          Assume that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided otherwise in such designation, or unless the Company shall have
      delivered a written revocation of such authority to the Trustee;

    

    

    (f)          The Company or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and in the Trustee’s best judgment, except for the Trustee’s gross
      negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee, which counsel may be the
      Company’s counsel), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained)
      which the Trustee believes, in good faith and with reasonable care, to be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or
      rescission of this Agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its prior
      written consent thereto;

    
      
        

    

    

    

    (g)          Verify the accuracy of the information contained in the Registration Statement;

    

    

    (h)          Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as contemplated by the Registration Statement;

    

    

    (i)          File information returns with respect to the Trust Account with any local, state or federal taxing authority or provide periodic written statements to the Company documenting the taxes payable by the
      Company, if any, relating to any interest income earned on the Property;

    

    

    (j)          Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and activities relating to, the Trust Account, regardless of whether such tax is
      payable by the Trust Account or the Company, including, but not limited to, franchise and income tax obligations, except pursuant to Section 1(j) hereof; or

    

    

    (k)          Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i), 1(j) and 1(k) hereof.

    

    

    4.          Trust Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies
      in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without
      limitation, under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account.

    

    

    5.          Termination. This Agreement shall terminate as follows:

    

    

    (a)          If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable efforts to locate a successor trustee, pending which the Trustee shall
      continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed by the Company and has agreed to become subject to the terms of this Agreement, the Trustee shall
      transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this Agreement shall terminate; provided, however,
      that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited with any court in the State of
      New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or

    

    

    (b)          At such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance with the provisions of Section 1(i) hereof and distributed the Property in
      accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to Section 2(b).

    
      
        

    

    

    

    6.          Miscellaneous.

    

    

    (a)          The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds transferred from the Trust Account. The Company and the Trustee will
      each restrict access to confidential information relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained access to such
      confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied to it by the Company, including, account names, account numbers, and all other identifying
      information relating to a Beneficiary, Beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability or expense
      resulting from any error in the information or transmission of the funds.

    

    

    (b)          This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application
      of the substantive laws of another jurisdiction.

    

    

    (c)          This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for Sections 1(i), 1(j) and 1(k) hereof (which
      sections may not be modified, amended or deleted without the affirmative vote of sixty-five percent (65%) of the then outstanding shares of Common Stock and Class B common stock, par value $0.0001 per share, of the Company, voting together as a
      single class; provided that no such amendment will affect any Public Stockholder who has properly elected to redeem his, her or its shares of Common Stock in connection with a stockholder vote sought to amend this Agreement), this Agreement or any
      provision hereof may only be changed, amended or modified (other than to correct a typographical error) by a writing signed by each of the parties hereto.

    

    

    (d)          The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM,
      CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.

    

    

    (e)          Any notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing and shall be sent by express mail or similar private courier service, by
      certified mail (return receipt requested), by hand delivery, facsimile transmission or by electronic mail:

    Dear Mr. Wolf and Ms. Gonzalez:

    

    

    Pursuant to Section 1(i) of the Investment Management Trust Agreement between Fortistar Sustainable Solutions Corp. (the “Company”) and Continental Stock
      Transfer & Trust Company (the “Trustee”), dated as of January 29, 2021 (the “Trust Agreement”), this is to advise you that the
      Company has entered into an agreement with                   (the “Target Business”) to consummate a business combination with Target Business (the “Business Combination”) on or about [insert date].  The Company shall notify you at least seventy-two (72) hours in advance of the actual date (or such shorter time period as you may agree) of the consummation of the
      Business Combination (the “Consummation Date”).  Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement.

    

    

    In accordance with the terms of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account, and to transfer the proceeds into the above-referenced account at J.P. Morgan
      Chase Bank, N.A. to the effect that, on the Consummation Date, all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Company, and solely with respect to the Deferred Discount, the
      [Underwriters], shall direct on the Consummation Date.  It is acknowledged and agreed that while the funds are on deposit in the trust operating account at J.P. Morgan Chase Bank, N.A. awaiting distribution, neither the Company nor the Underwriters
      will earn any interest or dividends.

    

    

    On the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has been consummated, or will be consummated substantially, concurrently with your transfer of
      funds to the accounts as directed by the Company (the “Notification”) and (ii) the Company shall deliver to you (a) [an affidavit] [a certificate] of the Chief Executive Officer of the
      Company, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held and (b) [joint written instruction signed by the Company and any of the Representatives] with respect to the transfer
      of the funds held in the Trust Account, including payment of amounts owed to public stockholders who have properly exercised their redemption rights and express instructions to pay the Deferred Discount from the Trust Account directly to the account
      or accounts directed by the [Underwriters] (the “Instruction Letter”).  You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt
      of the Notification and the Instruction Letter, in accordance with the terms of the Instruction Letter.  In the event that certain deposits held in the Trust Account may not be liquidated by the Consummation Date without penalty, you will notify the
      Company in writing of the same and the Company shall direct you as to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company.  Upon the distribution of all the funds, net of any payments
      necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated.

    
      
        

    

    

    

    In the event that the Business Combination is not consummated on the Consummation Date described in the notice thereof and we have not notified you on or before the original Consummation Date of a new Consummation Date,
      then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation Date as
      set forth in the notice as soon thereafter as possible.

    Dear Mr. Wolf and Ms. Gonzalez:

      Common Stock if the Company has not consummated an initial Business Combination within such time as is described in the Company’s amended and restated certificate of incorporation or (B) with respect to any other provision relating to stockholders’
      rights or pre-initial Business Combination activity. As such, you are hereby directed and authorized to transfer (via wire transfer) such funds promptly upon your receipt of this letter to the redeeming Public Stockholders in accordance with your
