Exhibit 4.4

    

    

    WARRANT AGREEMENT

    

    

    ARYA SCIENCES ACQUISITION CORP II

    

    

    and

    

    

    CONTINENTAL STOCK TRANSFER & TRUST COMPANY

    

    

    Dated [●], 2020

    

    

    THIS WARRANT AGREEMENT (this “Agreement”), dated [●], 2020, is by and between ARYA Sciences Acquisition Corp II, a Cayman Islands exempted company (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (in such capacity, the “Warrant Agent”).

    

    

    WHEREAS, it is proposed that the Company enter into that certain Private Placement Units Purchase Agreement, with ARYA Sciences Holdings
      II, a Cayman Islands limited liability company (the “Sponsor”), pursuant to which the Sponsor will purchase an aggregate of
      450,000 Units (as defined below) (or up to 487,500 Units if the underwriters in the Public Offering (defined below) exercise their Over-allotment Option (as defined below) in full) simultaneously with the closing of the Offering (and the closing of
      the Over-allotment Option, if applicable) (the “Private Placement Units”). The Private Placement Units include an aggregate of
      150,000 private placement warrants (or 162,500 private placement warrants if the Over-allotment Option is exercised in full) (the “Private
        Placement Warrants”) bearing the legend set forth in Exhibit B hereto. Each Private Placement Warrant entitles the holder thereof to purchase one
      Ordinary Share (as defined below) at a price of $11.50 per share, subject to adjustment as described herein; and

    

    

    WHEREAS, in order to finance the Company’s transaction costs in connection with an intended initial merger, share exchange, asset
      acquisition, share purchase, reorganization or similar business combination, involving the Company and one or more businesses (a “Business
        Combination”), 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 $1,500,000 of such loans may be
      convertible into up to an additional 1,000,000 Private Placement Warrants at a price of $1.50 per Private Placement 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 Ordinary Share (as defined below) and one-third of one Public Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and deliver up to 4,791,667 redeemable warrants (including up to
      625,000 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 Class A ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares”), for $11.50 per share, subject to
      adjustment as described herein. Only whole Warrants are exercisable. A holder of the Public Warrants will not be able to exercise any fraction of a Warrant; and

    
      

      
        


      

    

    
    WHEREAS, the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1, File No. 333-238488, and a 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 Ordinary Shares 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 certificated 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 in book-entry form, 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 The Depository Trust Company (the “Depositary”)
      (such institution, with respect to a Warrant in its account, a “Participant”).

    
      

      2

      
        


      

    

    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 (“Definitive Warrant Certificates”) 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, Chief Business 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, 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.

    

    

    2.4.         Detachability of Warrants. The Ordinary Shares 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 Jefferies LLC and Goldman Sachs & Co. LLC, but in no event shall the Ordinary Shares 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 then 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 Current Report on Form 8-K, and (B) the Company issues a press release announcing when such separate trading shall begin.

    

    

    2.5.         Fractional Warrants. The Company shall not issue fractional Warrants other than as part of the Units, each of which is comprised of one Ordinary Share and one-third of one whole Public
      Warrant. If, upon the detachment of Public Warrants from the 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.

    
      

      3

      
        


      

    

    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) including the Ordinary Shares issuable upon exercise of the Private Placement
      Warrants, may not be transferred, assigned or sold until thirty (30) days after the completion by the Company of an initial Business Combination, (iii) shall not be redeemable by the Company pursuant to Section 6.1 hereof and (iv) shall only be
      redeemable by the Company pursuant to Section 6.2 if the Reference Value (as defined below) is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof); provided, however, that in the case of (ii), the Private Placement
      Warrants and any Ordinary Shares 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 or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates;

    

    

    (b)           in the case of an individual, by gift
      to a member of one 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 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 Business Combination at prices no greater than the price at which the Private Placement Warrants or Ordinary Shares, as applicable, were originally purchased;

    

    

    (f)            by virtue of the Sponsor’s
      organizational documents upon liquidation or dissolution of the Sponsor;

    

    

    (g)           to the Company for no value for
      cancellation in connection with the consummation of our initial Business Combination;

    

    

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

    

    

    (i)            in the event of the Company’s
      completion of a liquidation, merger, share exchange or other similar transaction which results in all of the public shareholders having the right to exchange their Ordinary Shares 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 (f), these permitted transferees (the “Permitted Transferees”) must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.

    
      

      4

      
        


      

    

    3.             Terms and Exercise of Warrants.

    

    

    3.1.         Warrant Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of
      Ordinary Shares 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 (including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder)
      described in the prior sentence at which Ordinary Shares 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 fifteen (15) Business Days (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed or applicable law); provided that the Company shall provide at least five (5) 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”) (A) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a Business Combination, and (ii) the date that is twelve (12) months from the date of the
      closing of the Offering, and (B) terminating at the earliest to occur of (x) 5:00 p.m., New York City time on 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 memorandum and articles of association, as amended from time to time, if the Company fails to complete a Business Combination, and (z) other than with respect to the Private Placement
      Warrants then held by the Sponsor or its Permitted Transferees with respect to a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof),
      Section 6.2 hereof, 5:00 p.m., New York City time on 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 or a valid exemption
      therefrom being available. 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 its Permitted Transferees in connection with a
      redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section 6.2 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 its Permitted Transferees in the event of a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share (subject to
      adjustment in compliance with Section 4 hereof), Section 6.2 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.

    
      

      5

      
        


      

    

    3.3.         Exercise of Warrants.

    

    

    3.3.1.      Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant 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 (“Election to Purchase”) any Ordinary Shares 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 Ordinary Share 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 Ordinary Shares and
      the issuance of such Ordinary Shares, as follows:

    

    

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

    

    

    (b)           [Reserved];

    

    

    (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 Ordinary Shares equal to (i) if in connection with a redemption of Private Placement Warrants
      pursuant to Section 6.2 hereof, as provided in Section 6.2 hereof
      with respect to a Make-Whole Exercise (as defined below) and (ii) in all other scenarios the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Sponsor Exercise Fair Market Value” (as defined in this subsection 3.3.1(c)) over the Warrant Price by (y) the Sponsor Exercise Fair Market Value. Solely for purposes of this subsection 3.3.1(c),
      the “Sponsor Fair Market Value” shall mean the average last reported sale price of the Ordinary Shares for the ten (10) trading
      days ending on the third (3rd) trading day prior to the date on which notice of exercise of the Private Placement Warrant is sent to the Warrant Agent;

    

    

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

    

    

    (e)           as provided in Section 7.4 hereof.

    

    

    3.3.2.      Issuance of Ordinary Shares 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 Ordinary Shares to which he, she or it is entitled, registered in such name or names as may
      be directed by him, her or it on the register of members of the Company, 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 as to which such Warrant
      shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any Ordinary Shares 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 with respect to the Ordinary Shares underlying the Public Warrants is then effective and a prospectus relating thereto is current, 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 Ordinary Shares upon exercise of a Warrant unless the Ordinary Shares issuable upon such Warrant exercise have been registered,
      qualified or deemed to be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Warrants. Subject to Section 4.5 of this Agreement, a Registered Holder of Warrants may exercise
      its Warrants only for a whole number of Ordinary Shares. 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 an Ordinary Share, the Company shall round down to the nearest whole number, the number of Ordinary Shares to be issued to such holder.

    
      

      6

      
        


      

    

    3.3.3.      Valid Issuance. All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

    

    

    3.3.4.      Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for Ordinary Shares is issued and who is registered in the register of members of the
      Company shall for all purposes be deemed to have become the holder of record of such Ordinary Shares 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 register of members 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 at the close of business on the next succeeding date on which the share transfer books or book-entry system are open.

    

    

    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% (the “Maximum Percentage”) of the Ordinary Shares outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the
      aggregate number of Ordinary Shares beneficially owned by such person and its affiliates shall include the number of Ordinary Shares issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but
      shall exclude Ordinary Shares 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 shares 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 Ordinary Shares, the holder may rely on the
      number of outstanding Ordinary Shares 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 Continental Stock Transfer & Trust Company, as transfer agent (in such capacity, the “Transfer Agent”), setting forth the number of Ordinary Shares 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 Ordinary Shares then outstanding. In any case, the number of issued and outstanding Ordinary Shares 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 issued and outstanding Ordinary Shares 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.         Share Capitalizations.

    

    

    4.1.1.      Sub-Divisions. If after the date hereof, and subject to the provisions of Section 4.5 below, the number of issued and outstanding Ordinary Shares is increased by a capitalization or share
      dividend of Ordinary Shares, or by a split-up of Ordinary Shares or other similar event, then, on the effective date of such capitalization or share dividend, split-up or similar event, the number of Ordinary Shares issuable on exercise of each
      Warrant shall be increased in proportion to such increase in the issued and outstanding Ordinary Shares. A rights offering made to all or substantially all holders of Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than
      the “Historical Fair Market Value” (as defined below) shall be deemed a share dividend of a number of Ordinary Shares equal to the product of (i) the number of Ordinary Shares 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 Ordinary Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights offering divided by (y) the Historical Fair
      Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for Ordinary Shares, 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) “Historical Fair
        Market Value” means the volume weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading day prior to the first date on which the Ordinary Shares trade on the applicable exchange or in the
      applicable market, regular way, without the right to receive such rights. No Ordinary Shares shall be issued at less than their par value.

    
      

      7

      
        


      

    

    4.1.2.      Extraordinary Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all or substantially all of the holders of the Ordinary Shares  a dividend
      or make a distribution in cash, securities or other assets on account of such Ordinary Shares (or other shares 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 Ordinary Shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of the Ordinary Shares in connection with a shareholder
      vote to amend the Company’s amended and restated memorandum and articles of association (i) to modify the substance or timing of the Company’s obligation to provide holders of Ordinary Shares the right to have their shares redeemed in connection with
      the Company’s initial Business Combination or to redeem 100% of the Company’s public shares if it does not complete its initial Business Combination within the time period required by the Company’s Amended and Restated Memorandum and Articles of
      Association, as amended from time to time, or (ii) with respect to any other provision relating to the rights of holders of Ordinary Shares or (e) in connection with the redemption of 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 Company’s board of directors (the “Board”), in good faith) of any securities or other assets paid on each Ordinary Share
      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 all other cash dividends and cash distributions paid on the Ordinary Shares during the 365-day period ending on the date of declaration of such dividend or distribution does
      not exceed $0.50 (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
      Ordinary Shares issuable on exercise of each Warrant but only with respect to the amount of aggregate cash dividends and cash distributions equal to or less than $0.50 per Share).

    

    

    4.2.         Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.5 hereof, the number of issued and outstanding Ordinary Shares is decreased by a consolidation,
      combination, reverse share split or reclassification of Ordinary Shares or other similar event, then, on the effective date of such consolidation, combination, reverse share split, reclassification or similar event, the number of Ordinary Shares
      issuable on exercise of each Warrant shall be decreased in proportion to such decrease in issued and outstanding Ordinary Shares.

    

    

    4.3.         Adjustments in Exercise Price. Whenever the number of Ordinary Shares 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 Ordinary Shares purchasable upon the exercise of the Warrants
      immediately prior to such adjustment, and (y) the denominator of which shall be the number of Ordinary Shares so purchasable immediately thereafter.

    4.4.         Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding Ordinary Shares (other than a change under Section 4.1
      or Section 4.2 hereof or that solely affects the par value of such Ordinary Shares), 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 issued and outstanding Ordinary Shares), 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 Ordinary Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or 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
      Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares (other than a tender, exchange or redemption offer made by the Company in connection with redemption rights
      held by shareholders of the Company as provided for in the Company’s amended and restated memorandum and articles of association or as a result of the repurchase of Ordinary Shares by the Company if a proposed initial Business Combination is
      presented to the shareholders 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) 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) 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) more than 50% of the issued and outstanding Ordinary Shares, 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 shareholder 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
      Ordinary Shares 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 Ordinary Shares in the applicable event is payable in the form of 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 (assuming zero dividends) (“Bloomberg”). For purposes of
      calculating such amount, (i) Section 6 of this Agreement shall be taken into account, (ii) the price of each Ordinary Share shall be the volume weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading
      day prior to the effective date of the applicable event, (iii) 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 (iv) 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 Ordinary Shares consists exclusively of cash, the amount of such cash per Ordinary Share, and (ii) in all other cases, the
      volume weighted average price of the Ordinary Shares 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 Ordinary
      Shares 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 shall the Warrant Price be reduced to less than the par value per share issuable upon exercise of such Warrant.

    4.5.         Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares 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 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, 4.4 or 4.5, 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 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 Ordinary Shares to be issued to such holder.

    
      

      10

      
        


      

    

    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 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.

    

    

    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, 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. In the case of certificated Warrants, 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 except as otherwise provided herein or with respect
      to any Book-Entry Warrant, each Book-Entry Warrant may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depository, or to a nominee of a successor depository; provided further, 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.

    

    

    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 during the
      Exercise Period, 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 $0.01 per Warrant, provided that (a) the Reference Value equals or exceeds $18.00
      per share (subject to adjustment in compliance with Section 4 hereof) and (b) there is an effective registration statement covering the issuance of the Ordinary Shares 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).

    

    

    6.2.         Redemption of Warrants for Ordinary Shares. 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 during
      the Exercise Period, 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 (i) the last reported sales price of the
      Ordinary Shares equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4 hereof) on the trading day before the Company sends the notice of redemption to the Warrant Agent, (ii) the Private Placement Warrants are also
      concurrently called for redemption on the same terms as the outstanding Public Warrants and (iii) there is an effective registration statement covering the issuance of the Ordinary Shares 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 30-day 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 Ordinary Shares 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 “Redemption Fair Market Value” (as such term is defined in this Section 6.2) (a “Make-Whole
        Exercise”). Solely for purposes of this Section 6.2, the “Redemption Fair Market Value” shall mean the volume weighted
      average price of the Ordinary Shares for the ten (10) trading days ending on the third (3rd) trading day prior to the date on which notice of redemption pursuant to this Section 6.2 is sent to the Registered Holders.

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

    

    

    The share 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 hereof. The adjusted share prices in the column headings shall equal the share 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 shall the number of
      shares issued in connection with a Make-Whole Exercise exceed 0.365 Ordinary Shares per Warrant (subject to adjustment)

    
      

      13

      
        


      

    

    6.3.         Date Fixed for, and Notice of, Redemption; Redemption Price; Reference Value. In the event that the Company elects to redeem the Warrants pursuant to Sections 6.1 or 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. As used in this Agreement, (a) “Redemption Price” shall mean the price per Warrant at
      which any Warrants are redeemed pursuant to Sections 6.1 or 6.2 and (b) “Reference Value” shall mean the last reported sales
      price of the Ordinary Shares for any twenty (20) trading days within the thirty (30) trading-day period ending on the third trading day prior to the date on which notice of the redemption is given.

    

    

    6.4.         Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with 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. 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 (a) the redemption rights provided in Section 6.1 hereof 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 and (b) if the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the
      redemption rights provided in Section 6.2 hereof 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 in accordance with Section 2.6 hereof), the Company may redeem the Private Placement Warrants pursuant to Section 6.1 or 6.2 hereof, 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 hereof. 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, including for purposes of Section 9.8 hereof.

    

    

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

    

    

    7.1.         No Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder 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 shareholders in respect of the meetings of shareholders 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.

    
      

      14

      
        


      

    

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

    

    

    7.4.         Registration of Ordinary Shares; Cashless Exercise at Company’s Option.

    

    

    7.4.1.      Registration of the Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than twenty (20) Business Days after the closing of its initial Business
      Combination, it shall use its commercially reasonable efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise of the Warrants. The Company shall use
      its commercially reasonable efforts to cause the same to become effective within sixty (60) Business Days following the closing of its initial Business Combination and to maintain the effectiveness of such registration statement, and a current
      prospectus relating thereto, until the expiration or redemption of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the sixtieth (60th) Business Day
      following the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the sixty-first (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 issuance of the Ordinary Shares 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 another exemption) for that number of Ordinary Shares equal to the lesser of (A) the quotient
      obtained by dividing (x) the product of the number of Ordinary Shares 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 and (B) 0.365. Solely for
      purposes of this subsection 7.4.1, “Fair Market Value” shall mean the average last reported sales price of the Ordinary Shares
      for the ten (10) trading day period ending on the third 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 Ordinary Shares 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) 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 doubt, unless and until all of the Warrants have been exercised or have expired, the Company shall continue to be
      obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

    

    

    7.4.2.      Cashless Exercise at Company’s Option. If the Ordinary Shares are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the
      definition of a “covered security” under Section 18(b)(1) of the Securities Act, 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 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 Ordinary Shares issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its commercially reasonable efforts to register or qualify for sale the Ordinary Shares issuable
      upon exercise of the Public Warrant under applicable blue sky laws 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 Ordinary Shares 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.

    

    

    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, her or its 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 or other entity organized and existing under the laws of the State of New York, in good standing and having its principal office in the
      United States of America, 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 Ordinary Shares not later than the effective date of any such appointment.

    
      

      16

      
        


      

    

    8.2.3.      Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be consolidated or any entity 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

    9.3.         Applicable Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in all respects by the laws of the State of New
      York. Subject to applicable law, the Company hereby agrees that any action, proceeding or claim against it arising out of, or otherwise based on this Agreement shall 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, which jurisdiction shall be exclusive forum for any such action, proceeding or claim. The Company hereby waives any objection to such exclusive
      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.

    

    

    Any person or entity purchasing or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented
      to the forum provisions in this Section 9.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within the State of New York or the United States District Court
      for the Southern District of New York (a “foreign action”) in the name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of New York
      or the United States District Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant
      holder in any such enforcement action by service upon such warrant holder's counsel in the foreign action as agent for such warrant holder.

    

    

    9.4.         Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person, corporation or other entity 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 shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the Registered Holders of the Warrants.

    

    

    9.5.         Examination of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the Warrant Agent in the United States of America, for
      inspection by the Registered Holder of any Warrant. The Warrant Agent may require any such holder to submit such holder’s Warrant for inspection by the Warrant Agent.

    
      

      19

      
        


      

    

    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 (i) curing any ambiguity or to correct any mistake,
      including to conform the provisions hereof to the description of the terms of the Warrants and this Agreement set forth in the Prospectus, or defective provision contained herein, (ii) amending the definition of “Ordinary Cash Dividend” as
      contemplated by and in accordance with the second sentence of subsection 4.1.2 or (iii) adding or changing any 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 rights of the Registered Holders under this Agreement. All other modifications or amendments, including any modification or 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 and, solely with respect to any amendment to the terms of the Private
      Placement Warrants or any provision of this Agreement with respect to the Private Placement Warrants, 50% of the then-outstanding Private Placement 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 any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such
      invalid or unenforceable provision as may be possible and be valid and enforceable.

    ARYA Sciences Acquisition Corp II

    Incorporated Under the Laws of the Cayman Islands

    

    

    CUSIP [●]

    

    

    Warrant Certificate

    

    

    This Warrant
        Certificate certifies that [               ], or registered assigns, is the registered holder of [               ] warrant(s) (the “Warrants” and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001 par value (“Ordinary Shares”), of ARYA Sciences Acquisition Corp II, a Cayman Islands exempted company (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 nonassessable Ordinary Shares 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 Ordinary Share. Fractional shares shall not be issued
      upon exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number the number of Ordinary Shares
      to be issued to the Warrant holder. The number of Ordinary Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.

    

    

    The initial Exercise Price per one Ordinary Share for any Warrant is equal to $11.50 per share. The Exercise Price is subject to adjustment
      upon the occurrence of certain events as 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.

    [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  [               ] Ordinary Shares and are issued or to be issued pursuant to a Warrant Agreement dated as of [●], 2020 (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, respectively) 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 issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the Ordinary Shares 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 Ordinary Shares 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 an Ordinary Share, the Company shall, upon exercise, round
      down to the nearest whole number of Ordinary Shares 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 shareholder 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 [               ]
      Ordinary Shares and herewith tenders payment for such Ordinary Shares to the order of ARYA Sciences Acquisition Corp II (the “Company”)
      in the amount of $[               ] in accordance with the terms hereof. The undersigned requests that a certificate for such Ordinary Shares be registered in the name of [               ], whose address is  [               ] and that such Ordinary
      Shares be delivered to  [               ] whose address is [               ]. If said [               ] number of Ordinary Shares is less than all of the Ordinary Shares purchasable hereunder, the undersigned requests that a new Warrant Certificate
      representing the remaining balance of such Ordinary Shares 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 6.2 of the Warrant Agreement and a holder thereof elects to exercise its Warrant pursuant to a Make-Whole Exercise, the number of Ordinary Shares that this Warrant is exercisable for shall be
      determined in accordance with subsection 3.3.1(c) or Section 6.2
      of the Warrant Agreement, as applicable.

    

    

    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 Ordinary Shares 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 Ordinary Shares 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
      Ordinary Shares 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 Ordinary Shares. If said number of shares is less than all of the Ordinary Shares
      purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be registered in the name of [               ], whose address is 
      [               ] and that such Warrant Certificate be delivered to [               ], whose address is [               ].
