liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance with, the terms of a letter
from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A
or Exhibit B, as applicable, signed on behalf of the Company by its Chief Executive Officer, Chief Financial Officer or other
authorized officer of the Company, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account,
including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its income taxes, if
any (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses), only as directed in the Termination
Letter and the other documents referred to therein, or (y) upon the date which is (1) 24 months after the closing of the Offering
and (2) such later date as may be approved by the Company’s shareholders in accordance with the Company’s amended and
restated memorandum and articles of association, if a Termination Letter has not been received by the Trustee prior to such date, in which
case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B
and the Property in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to
the Company to pay its taxes, if any (less up to $100,000 of interest to pay dissolution expenses), shall be distributed to the Public
Shareholders of record as of such date. It is acknowledged and agreed that there should be no reduction in the principal amount per share
initially deposited in the Trust Account;


 


(j)            Upon
written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C

funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority, so long
as there is no reduction in the principal amount initially deposited in the Trust Account; provided, however, that to the
extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the
Trust Account as shall be designated by the Company in writing to make such distribution (it being acknowledged and agreed that any such
amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The written request of the Company
referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility
to look beyond said request;

written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit D

(l)            Not
make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i), (j) or (k) above.

    3


     


    

 


(b)            Subject
to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all reasonable and documented
expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by
it hereunder and in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection
with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property
or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful
misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding,
pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing
of such claim (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the right to conduct
and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect
to the selection of counsel, which consent shall not be unreasonably withheld, and the Company shall have the ability to supervise and
intervene under reasonable circumstances. The Trustee may not agree to settle any Indemnified Claim without the prior written consent
of the Company, which such consent shall not be unreasonably withheld. The Company may participate in such action with its own counsel;


 


(c)            Pay
the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual administration fee, and transaction
processing fee which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property
shall not be used to pay such fees unless and until it is distributed to, or on behalf of, the Company pursuant to Sections 1(i) through
1(k) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation
of the Offering. The Trustee shall refund to the Company the annual administration fee (on a pro rata basis) with respect to any period
after the liquidation of the Trust Account. The Company shall not be responsible for any other fees or charges of the Trustee except as
set forth in this Section 2(c) and as may be provided in Section 2(b) hereof;


 


(d)            In
connection with any vote of the Company’s shareholders regarding a merger, share exchange, asset acquisition, share purchase, reorganization
or similar business combination involving the Company and one or more businesses (the “Business Combination”),
provide to the Trustee an affidavit or certificate of the inspector of elections for the shareholder meeting verifying the vote of such
shareholders regarding such Business Combination;


 


(e)            Provide
the Representatives with a copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect
to any proposed withdrawal from the Trust Account promptly after it issues the same;


 


(f)            Unless
otherwise agreed between the Company and the Representatives, ensure that any Instruction Letter (as defined in Exhibit A)
delivered in connection with a Termination Letter in the form of Exhibit A expressly provides that the Deferred Discount is
paid directly to the account or accounts directed by the Representatives on behalf of the Underwriters prior to any transfer of the funds
held in the Trust Account to the Company or any other person;


 



    4


     


    

 


(g)            Instruct
the Trustee to make only those distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make
any distributions that are not permitted under this Agreement;


 


(h)            If
the Company seeks to amend any provisions of its amended and restated memorandum and articles of association (A) to modify the substance
or timing of the Company’s obligation to provide holders of the Ordinary Shares the right to have their shares redeemed in connection
with the Company’s initial Business Combination or to redeem 100% of the Ordinary Shares if the Company does not complete its initial
Business Combination within the time period set forth therein or (B) with respect to any other material provision relating to the
rights of holders of the Ordinary Shares or pre-initial Business Combination activity (in each case, an “Amendment”),
the Company will provide the Trustee with a letter (an “Amendment Notification Letter”) in the form of Exhibit D
providing instructions for the distribution of funds to Public Shareholders who exercise their redemption option in connection with such
Amendment; and


 


(i)            Within
four (4) business days after the Representatives, on behalf of the Underwriters, exercise their option to purchase additional units
(or any unexercised portion thereof) or such option to purchase additional units expires, provide the Trustee with a notice in writing
of the total amount of the Deferred Discount (with a copy to the Underwriters).

other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in

misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or
advice of counsel (including counsel chosen by the Trustee, which counsel may be the Company’s counsel), statement, instrument,

to the truth and acceptability of any information therein contained) which the Trustee believes, in good faith and with reasonable care,
to be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or
any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced by a written instrument

tax obligations, except pursuant to Section 1(j) hereof; or


 


(l)            Verify
calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i), 1(j) or

Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”)
to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it
may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation,
under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company
and its assets outside the Trust Account and not against the Property or any monies in the Trust Account.


 






    6


     


    

 


5.            Termination.
This Agreement shall terminate as follows:

of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee, including but not limited
to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this Agreement shall terminate; provided,
however, that in the event that the Company does not locate a successor trustee within one-hundred twenty (120) days of receipt
of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited with any court in the
State of New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall
be immune from any liability whatsoever; or


 


(b)            At
such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance with the provisions of
Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement
shall terminate except with respect to Section 2(b).


 


6.            Miscellaneous.


 


(a)            The
Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds transferred
from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures

but one instrument.


 


(c)            This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for
Section 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or deleted without
the affirmative vote of sixty-five percent (65%) of the then outstanding Ordinary Shares and Class B ordinary shares, par value $0.0001
per share, of the Company, voting together as a single class; provided that no such amendment will affect any Public Shareholder
who has properly elected to redeem his or her Ordinary Shares in connection with a shareholder vote to amend this Agreement (A) to
modify the substance or timing of the Company’s obligation to provide for the redemption of the Ordinary Shares in connection with
an initial Business Combination or to redeem 100% of its Ordinary Shares if the Company does not complete its initial Business Combination
within the time frame specified in the Company’s amended and restated memorandum and articles of association or (B) with respect
to any other provision relating to shareholders’ rights or pre-initial Business Combination activity), this Agreement or any provision

	Re:	Trust Account—Termination Letter


 


Ladies and Gentlemen:


 


Pursuant to Section 1(i) of the
Investment Management Trust Agreement between Excelsa Acquisition Corp. (the “Company”) and Continental Stock
Transfer & Trust Company (“Trustee”), dated as of ___________, 2021 (the “Trust Agreement”),
this is to advise you that the Company has entered into an agreement with ___________ (the “Target Business”)
to consummate a business combination with Target Business (the “Business Combination”) on or about [insert
date]. The Company shall notify you at least seventy-two (72) hours in advance of the actual date (or such shorter time period as
you may agree) of the consummation of the Business Combination (the “Consummation Date”). Capitalized terms
used but not defined herein shall have the meanings set forth in the Trust Agreement.


 


In accordance with the terms of the Trust
Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account, and to transfer the proceeds
into the trust operating account at JPMorgan Chase Bank, N.A. to the effect that, on the Consummation Date, all of the funds held in
the Trust Account will be immediately available for transfer to the account or accounts that the Representatives (with respect to
the Deferred Discount) and the Company shall direct on the Consummation Date. It is acknowledged and agreed that while the funds are
on deposit in said trust operating account at JPMorgan Chase Bank, N.A. awaiting distribution, neither the Company nor the
Representatives will earn any interest or dividends.


 


On the Consummation Date (i) counsel for the
Company shall deliver to you written notification that the Business Combination has been consummated, or will be consummated substantially
concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”), and
(ii) the Company shall deliver to you (a) a certificate of the Chief Executive Officer, Chief Financial Officer or other authorized
officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders,
if a vote is held and (b) joint written instruction signed by the Company and the Representatives with respect to the transfer of
the funds held in the Trust Account, including payment of amounts owed to public stockholders who have properly exercised their redemption
rights and express instructions to pay the Deferred Discount directly to the account or accounts directed by the Representatives from
the Trust Account (the “Instruction Letter”). You are hereby directed and authorized to transfer the funds held
in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance with the terms of the
