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 Class A ordinary
shares, $0.0001 par value per share (the “Ordinary Shares”), of Excelsa Acquisition 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 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.

[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 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. To the extent that any provision of this Warrant Certificate conflicts with the express provisions of the Warrant Agreement,
the provisions of the Warrant Agreement shall govern and be controlling.


 


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 (i) at the time of exercise
a registration statement covering the issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities
Act and a prospectus thereunder relating to the Ordinary Shares is current, (ii) at the time of exercise a valid exemption from
registration is available or (iii) through a “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.
