      CUSIP [•]

      

      

      Warrant Certificate

      

      

      This Warrant Certificate certifies that
        [ ], or its registered assigns, is the registered holder of [ ] warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001 par value, of B Capital Technology Opportunities Corp, 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 non-assessable 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 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 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.

      

      

      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 [ ] Ordinary
        Shares 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 limited purpose trust company, 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 a Ordinary Shares, 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 B Capital Technology Opportunities Corp. (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 or a Working Capital 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.

            7.4 of the Warrant Agreement.

        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 [ ].
