This Investment Management Trust Agreement (this
 “Agreement”) is made effective as of [●], 2022 by and between Mars Acquisition Corporation, a Cayman Islands
exempted company (the “Company”), and Continental Stock Transfer & Trust Company, a New York limited purpose
trust company (the “Trustee”).


 


WHEREAS, the Company’s registration statement
on Form S-1, File No. 333-265240 (“Registration Statement”) and prospectus (“Prospectus”)
for the initial public offering of the Company’s units (“Units”), each of which consists of one ordinary share
of the Company, par value $0.000125 per share (“Ordinary Share”), and one right to receive two-tenth of one Ordinary
Share (each, a “Right”) (such initial public offering referred to as the “IPO”) has been declared
effective as of the date hereof (“Effective Date”) by the Securities and Exchange Commission (capitalized terms used
herein and not otherwise defined shall have the meanings set forth in the Registration Statement);


 


WHEREAS, the Company has entered into an Underwriting
Agreement (“Underwriting Agreement”) with Maxim Group LLC as the representative (the “Representative”)
of the several underwriters (“Underwriters”) named therein;


 


WHEREAS, if a business combination (“Business
Combination”) is not consummated within the initial 12 month period following the closing of the IPO, the Company’s insiders
may extend such period two times by an additional three-months each time, up to a maximum of 18 months in the aggregate, by depositing
$600,000 (or $690,000 if the Underwriters’ over-allotment option is exercised in full) into Trust Account (as defined below) on
or prior to the applicable deadline. In exchange the sponsor or its affiliates or designees will receive non-interest bearing, unsecured
promissory notes equal to the amount of any such deposit;


 


WHEREAS, as described in the Prospectus, and in
accordance with the Company’s Amended and Restated Memorandum and Articles of Association (“Articles of Association”),
$60,000,000 ($69,000,000 if the over-allotment option is exercised in full) of the proceeds from the IPO and a simultaneous private placement
of Units will be delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United States
(the “Trust Account”) for the benefit of the Company and the holders of the Ordinary Shares included in the Units issued
in the IPO as hereinafter provided (the proceeds to be delivered to the Trustee and any interest subsequently earned thereon will be referred
to herein as the “Property”; the shareholders for whose benefit the Trustee shall hold the Property will be referred
to as the “Public Shareholders,” and the Public Shareholders and the Company will be referred to together as the “Beneficiaries”);


 


WHEREAS, the Company and the Trustee desire to
enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property.


 


NOW THEREFORE, IT IS AGREED:


 


1. Agreements and Covenants of Trustee. The Trustee hereby agrees
and covenants to:


 


(a) Hold the Property in trust for the Beneficiaries
in accordance with the terms of this Agreement in the Trust Account established by the Trustee initially at J.P. Morgan Chase Bank, N.A.

out as a money market fund selected by the Company meeting the conditions of paragraph (d) of Rule 2a-7 promulgated under the
Investment Company Act, which invest only in direct U.S. government treasury obligations or (ii) cause the brokerage institution
referred to in 1(a) above to place the Property in a cash demand deposit account; it being understood that unless the Company instructs
the Trustee to do either of the foregoing, the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s
instructions hereunder and the Trustee may earn bank credits or other consideration during such periods;


 


(d) Collect and receive, when due, all principal

for protecting or enforcing any right or interest arising from the Property if, as, and when instructed by the Company to do so;


 


(h) Render to the Company monthly written
statements of the activities of and amounts in the Trust Account reflecting all receipts and disbursements of the Trust Account;


 


(i) Commence liquidation of the Trust Account
only after and promptly after 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 and, in the case of a Termination Letter in a form substantially similar to that attached hereto as Exhibit A,
jointly acknowledged and agreed to by the Representative, and complete the liquidation of the Trust Account and distribute the Property
in the Trust Account only as directed in the Termination Letter and the other documents referred to therein; provided, however, that in
the event that a Termination Letter has not been received by the Trustee within the period of time (the “Last Date”)
provided in the Company’s Articles of Association, the Trust Account shall be liquidated in accordance with the procedures set forth
in the Termination Letter attached as Exhibit B hereto and distributed to the Public Shareholders as of the Last Date; and


 


(j) Upon receipt of a letter (an “Amendment
Notification Letter”) in the form of Exhibit C, signed on behalf of the Company by an authorized officer, distribute

Shares for which such Public Shareholders have exercised redemption rights in connection with such Amendment.


 


2. Limited Distributions of Income from Trust Account.

3. Agreements and Covenants of the Company. The Company agrees
and covenants to:


 


(a) Give all instructions to the Trustee hereunder
in writing, signed by any one of the Company’s authorized officers. The Trustee shall be entitled to rely on such written instructions
from the Company confirmed by telephone instruction from a person which the Trustee in good faith believes to be given by any one of the
persons authorized above to give written instructions;


 



    


     


    

 


(b) Subject to the provisions of Section 5
of this Agreement, hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel
fees and disbursements, or losses suffered by the Trustee in connection with any claim, potential claim, action, suit, or other proceeding
brought against the Trustee which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the
Property or any income earned from investment of the Property, except for expenses and losses resulting from the Trustee’s gross

any action, suit, or proceeding, pursuant to which the Trustee intends to seek indemnification under this paragraph, it shall notify the
Company in writing of such claim (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the right

on Schedule A hereto, 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 and further agreed that any fees owed to the Trustee shall be deducted by the Trustee
pursuant to Section 1(i) solely in connection with the consummation of a business combination (a “Business Combination”).
The Company shall pay the Trustee the initial acceptance fee and first year’s fee at the consummation of the IPO and thereafter
on the anniversary of the Effective Date;


 


(d) In connection with any vote of the Company’s

of soliciting proxies and/or tabulating shareholder votes verifying the vote of the Company’s shareholders regarding such Business
Combination;


 


(e) In the event that the Company directs
the Trustee to commence liquidation of the Trust Account pursuant to Section 1(i), the Company agrees that it will not direct
the Trustee to make any payments that are not specifically authorized by this Agreement;


 


(f) If the Company has an Amendment approved
by its shareholders, provide the Trustee with an Amendment Notification Letter in the form of Exhibit C providing instructions
for the distribution of funds to Public Shareholders who exercise their redemption rights in connection with such Amendment;


 


(g) Provide the Representative with a copy
of any Termination Letter, Amendment Notification Letter, and/or any other correspondence that it issues to the Trustee with respect to
any proposed withdrawal from the Trust Account promptly after such issuance; and

(as defined in Exhibit A) delivered in connection with a Termination Letter in a form substantially similar to that attached
hereto as Exhibit A that the Business Combination Fee be paid directly to the account or accounts directed by the Representative
on behalf of the Underwriters.


 


4. Limitations of Liability. The Trustee shall have no responsibility

arising out of its own gross negligence, fraud or willful misconduct;


 


(b) Institute any proceeding for the collection
of any principal and income arising from, or institute, appear in, or defend any proceeding of any kind with respect to, any of the Property
unless and until it shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced
or guaranteed to it funds sufficient to pay any expenses incident thereto;


 



    


     


    

 


(c) Change the investment of any Property,
other than in compliance with Section 1(c);


 


(d) Refund any depreciation in principal of
any Property;


 


(e) Assume that the authority of any person
designated by the Company to give instructions hereunder shall not be continuing unless provided otherwise in such designation, or unless
the Company shall have delivered a written revocation of such authority to the Trustee;


 


(f) The 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 good faith and in the exercise of
its own best judgment (provided, that with respect to its duties under Sections 1(i), 1(j), and 2(a) above,
the Trustee shall take no action except as set forth in written instructions from the Company, confirmed by telephone, in accordance with
Section 3(a)), except for its gross negligence, fraud or willful 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, report, or other paper or document (not only as to its due execution
and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained)
which is believed by the Trustee, in good faith, to be genuine and to be signed or presented by the proper person or persons (provided,
that with respect to its duties under Sections 1(i), 1(j), and 2(a) above, the Trustee shall take no action
except as set forth in written instructions from the Company, confirmed by telephone, in accordance with Section 3(a)). 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 delivered to the Trustee signed by the proper party or parties and, if the
duties or rights of the Trustee are affected, unless it shall give its prior written consent thereto;


 


(g) Verify the correctness of the information
set forth in the Registration Statement or to confirm or assure that any Business Combination consummated by the Company or any other
action taken by it is as contemplated by the Registration Statement;


 


(h) File local, state, and/or federal tax
returns or information returns with any taxing authority on behalf of the Trust Account or deliver payee statements to the Company documenting
the taxes, if any, payable by the Company or the Trust Account, relating to the income earned on the Property;


 


(i) Pay any taxes on behalf of the Trust Account
(it being expressly understood that the Property shall not be used to pay any such taxes and that such taxes, if any, shall be paid by
the Company from funds not held in the Trust Account or released to it under Section 2(a) hereof);


 


(j) Imply obligations, perform duties, inquire,
or otherwise be subject to the provisions of any agreement or document other than this agreement and that which is expressly set forth
herein; or


 


(k) Verify calculations, qualify, or otherwise
approve Company requests for distributions pursuant to Sections 1(i), 1(j), and 2(a) above.


 


5. Trust 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 3(b) or Section 3(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. Termination. This Agreement shall terminate as follows:


 


(a) If the Trustee gives written notice to
the Company that it desires to resign under this Agreement, the Company shall use its reasonable efforts to locate a successor trustee
during which time the Trustee shall act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor
trustee has been appointed by the Company and has agreed to become subject to the terms 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 ninety (90) 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 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 3(b) and
Section 5.


 


7. 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 funds being transferred to or from the Trust Account
to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained
access to such information, or of any change in its authorized personnel. In executing funds transfers, the Trustee will rely upon all
information supplied to it by the Company, including account names, account numbers, and all other identifying information relating to
a beneficiary, beneficiary’s bank, or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence,
fraud, or willful misconduct, the Trustee shall not be liable for any loss, liability, or expense resulting from any error in the information
supplied to it or funds transferred based on such information.


 


(b) This Agreement shall be governed by and
construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that
would result in the application of the substantive laws of another jurisdiction. The parties hereto consent to the jurisdiction and venue
of any state or federal court located in the City of New York, Borough of Manhattan, for purposes of resolving any disputes hereunder.
As to any claim, cross-claim, or counterclaim in any way relating to this Agreement, each party waives the right to trial by jury.


 


(c) This Agreement may be executed in several
original or facsimile counterparts, each one of which shall constitute an original, and together shall constitute but one instrument.

and understanding of the parties hereto with respect to the subject matter hereof. Except for Sections 1(i) and 1(j) (which
sections may not be modified, amended or deleted without the affirmative vote of a majority of the then outstanding Ordinary Shares; provided
that no such amendment will affect any Public Shareholder who has otherwise indicated his, her or its election to redeem his, her or its
Ordinary Shares in connection with a vote sought to amend this Agreement), this Agreement or any provision hereof may only be changed,
amended or modified by a writing signed by each of the parties hereto; provided, however, that no such change, amendment or modification
may be made without the prior written consent of the Representative. The Trustee may require from Company counsel an opinion as to the
propriety of any proposed amendment.
