WARRANTS 
 THIS WARRANT
SHALL BE NULL AND VOID IF NOT EXERCISED PRIOR TO 
 THE EXPIRATION OF THE EXERCISE PERIOD PROVIDED FOR 

IN THE WARRANT AGREEMENT DESCRIBED BELOW 

MOBIV ACQUISITION CORP 

Formed under the Law of the State of Delaware 

CUSIP                  

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, $0.000001 par value per share (“Common Stock”), of Mobiv
Acquisition Corp (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 shares of fully paid and non-assessable 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 to the extent applicable through a “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 Warrant is initially exercisable for one fully
paid and non-assessable Ordinary Share. No fractional shares will 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 will, upon exercise, round down to the nearest whole number of the number of shares of Common Stock to be issued to the holder. The number of shares of Common Stock 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 share of Class A
common stock for any whole Warrant is equal to $11.50 per whole share. Only whole Warrants may be exercised. 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 null and 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.

Upon any exercise of the Warrant for less than the total number of shares of full Common Stock provided for herein, there shall be issued to
the registered holder hereof or the registered holder’s assignee a new Warrant Certificate covering the number of shares of Common Stock in respect of which the Warrant has not been exercised. 

This Warrant does not entitle the registered holder to any of the rights of a stockholder of the Company. This Warrant Certificate shall be
governed by and construed in accordance with the law 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
                     shares of Class A Common Stock and are issued or to be issued pursuant to a Warrant Agreement dated as of
            , 2022 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation,
as warrant agent (or successor warrant agent) (collectively, 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 designated office(s) 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 an Ordinary Share, 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. 

The Company reserves the right to call the Warrant at any time prior to its exercise with a notice of call in writing to the holders of record
of the Warrant, pursuant to the terms set forth in the Warrant Agreement. 
 Warrant Certificates, when surrendered at the designated
office(s) 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(s) 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 charges 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.
