This Investment Management
Trust Agreement (this “Agreement”) is made effective as of July 15, 2021, by and between StoneBridge Acquisition
Corporation, a Cayman Islands exempted company (the “Company”), and Continental Stock Transfer & Trust
Company, a New York corporation (the “Trustee”).


 


WHEREAS, the Company’s
registration statement on Form S-1, File No. 333-253641 (the “Registration Statement”) and prospectus
(the “Prospectus”) for the initial public offering of the Company’s units (the “Units”),
each of which consists of one Class A ordinary share of the Company, of par value $0.0001 per share (the “Ordinary Shares”),
and one-half of one redeemable warrant, each whole warrant entitling the holder thereof to purchase one Ordinary Share (such initial public
offering hereinafter referred to as the “Offering”), has been declared effective as of the date hereof by the
U.S. Securities and Exchange Commission;


 


WHEREAS, the Company has entered
into an Underwriting Agreement (the “Underwriting Agreement”) with Cantor Fitzgerald & Co., as representative
(the “Representative”) of the several underwriters (the “Underwriters”) named therein;


 


WHEREAS, as described in the
Prospectus, $202,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as defined in the Underwriting
Agreement) (or $232,300,000, if the Underwriters’ over-allotment option is exercised in full) 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 Offering as hereinafter provided
(the amount to be delivered to the Trustee (and any interest subsequently earned thereon) is 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, pursuant to the Underwriting
Agreement, a portion of the Property equal to $9,000,000 (or up to $10,350,000 if the Underwriter’s over-allotment option is exercised

with the consummation of the Business Combination (as defined below) (the “Deferred Discount”); and


 


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
in the United States at J.P. Morgan Chase Bank, N.A. (or at another U.S.-chartered commercial bank with consolidated assets of $100 billion
or more) in the United States, maintained by the Trustee, and at a brokerage institution selected by the Trustee that is reasonably satisfactory
to the Company;


 






    1 


     


    

 


(b)           Manage,
supervise and administer the Trust Account subject to the terms and conditions set forth herein;


 


(c)           In
a timely manner, upon the written instruction of the Company, invest and reinvest the Property solely in United States government securities
within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less,
or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated
under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government treasury obligations,
as determined by the Company; it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting
the Company’s written instructions hereunder and the Trustee may earn bank credits or other consideration;


 


(d)           Collect
and receive, when due, all principal, interest or other income arising from the Property, which shall become part of the “Property,”
as such term is used herein;


 


(e)           Promptly
notify the Company and the Representative of all communications received by the Trustee with respect to any Property requiring action
by the Company;


 


(f)            Supply
any necessary information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s
preparation of the tax returns relating to assets held in the Trust Account;


 


(g)           Participate
in any plan or proceeding 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 (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, President,
Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized officers of
the Company, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest not
previously released to the Company to pay its taxes (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,
the later of (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 not previously
released to the Company to pay its taxes (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses)
shall be distributed to the Public Shareholders of record as of such date; provided, however, that in the event the Trustee
receives a Termination Letter in a form substantially similar to Exhibit B hereto, or if the Trustee begins to liquidate the
Property because it has received no such Termination Letter by the date specified in clause (y) of this Section 1(i) the
Trustee shall keep the Trust Account open until twelve (12) months following the date the Property has been distributed to the Public
Shareholders.


 






    2 


     


    

 


(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,
withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to
cover any tax obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property,
which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the Company
shall forward such payment to the relevant taxing authority; 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, so long as there is no reduction in the principal amount initially deposited in 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;


 


(k)             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 D,
the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem Ordinary Shares from Public
Shareholders properly submitted in connection with a shareholder vote to approve an amendment to the Company’s amended and restated
memorandum and articles of association to modify the substance or timing of the ability of Public Shareholders to seek redemption in connection
with an initial Business Combination or the Company’s obligation to redeem 100% of its public Ordinary Shares if the Company has
not consummated an initial Business Combination within such time as is described in Section 1(i) of the Agreement. The written
request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and
the Trustee shall have no responsibility to look beyond said request; and


 


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


 


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


 


(a)             Give
all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, Chief Executive Officer, Chief
Financial Officer, President or Secretary. In addition, except with respect to its duties under Sections 1(i), 1(j) and
1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or telephonic advice
or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give
written instructions, provided that the Company shall promptly confirm such instructions in writing;


 






    3 


     


    

 


(b)             Subject
to Section 4 hereof, 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 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. 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 the closing of the Business Combination (defined below). 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),
Schedule A 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 Representative 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 Representative, 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 Representative 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; and


 


(h)             Within
four (4) business days after the Underwriters exercise the over-allotment option (or any unexercised portion thereof) or such over-allotment
expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount.


 


3.             Limitations
of Liability. The Trustee shall have no responsibility or liability to:


 


(a)            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;


 


(b)            Take
any action with respect to the Property, other than as directed in Section 1 hereof, and the Trustee shall have no liability

(c)            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 written 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;


 


(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 Trustee’s best judgment, except for the Trustee’s 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 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

thereto;

(j)             Prepare,
execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and activities relating
to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, except pursuant to Section 1(j) hereof;
or


 


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

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.


 


5.             Termination.

to locate a successor trustee, pending which the Trustee shall continue to 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 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 


     


    

 


6.             Miscellaneous.

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
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 confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall
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

to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. 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.


 


(c)             This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for
Sections 1(i), 1(j), 1(k) and 1(l) hereof (which sections may not be modified, amended or deleted
without the affirmative vote of sixty five percent (65%) of the then issued and 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 otherwise indicated his election to redeem his Ordinary Shares in connection with a shareholder vote sought
to amend this Agreement), this Agreement or any provision hereof may only be changed, amended or modified (other than to correct a typographical
error) by a writing signed by each of the parties hereto. Except for any liability arising out of the Trustee’s gross negligence,
fraud or willful misconduct, the Trustee may rely conclusively on the certification from the inspector or elections referenced above and
shall be relieved of all liability to any party for executing the proposed amendment in reliance thereon.


 


(d)             The
parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, State of New York,
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.

Re: Trust Account No. [●]
Termination Letter


 


Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section 1(i) of
the Investment Management Trust Agreement between StoneBridge Acquisition Corporation (the “Company”) and Continental
Stock Transfer & Trust Company (the “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 the 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 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
to a segregated account held by you on behalf of the Beneficiaries 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 Company shall direct on the Consummation
Date (including as directed to it by the Representative on behalf of the Underwriters (with respect to the Deferred Discount)). It is
acknowledged and agreed that while the funds are on deposit in the trust operating account at J.P. Morgan Chase Bank, N.A. awaiting distribution,
the Company will not 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 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, which verifies that the Business Combination has been
approved by a vote of the Company’s shareholders, if a vote is held and (b) a joint written instruction signed by the Company
and the Representative with respect to the transfer of the funds held in the Trust Account, including payment of amounts owed to public
shareholders who have properly exercised their redemption rights and payment of the Deferred Discount to the Representative 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 Instruction
Letter. In the event that certain deposits held in the Trust Account may not be liquidated by the Consummation Date without penalty, you
will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in the Trust Account
and be distributed after the Consummation Date to the Company. Upon the distribution of all the funds, net of any payments necessary for
reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated.


 


[Exhibit A
to Investment Management Trust Agreement]


 






     


     


    

 


In the event that the Business
Combination is not consummated on the Consummation Date described in the notice thereof and we have not notified you on or before the
original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the
funds held in the Trust Account shall be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately
following the Consummation Date as set forth in the notice as soon thereafter as possible.
