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, $0.000005 par value per share (the “Ordinary Shares”), of ECARX Holdings Inc., 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 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.

[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 of the Company
and are issued or to be issued pursuant to (i) the Assignment, Assumption and Amendment Agreement (the “Assignment, Assumption
and Amendment Agreement”) dated as of __________ duly executed and delivered by Continental Stock Transfer & Trust Company,
a New York corporation, as warrant agent (the “Warrant Agent”), the Company, and COVA Acquisition Corp. and
(ii) the Warrant Agreement dated as of February 4, 2021 duly executed and delivered by COVA Acquisition Corp. to the Warrant Agent and
as amended by the Assignment, Assumption and Amendment Agreement (the “Warrant Agreement”). The 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 U.S. Securities Act of 1933, as amended, 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.
