Re: Initial Public Offering

 

Ladies and Gentlemen:

 

This letter (this “Letter
Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
to be entered into by and between StoneBridge Acquisition Corporation, a Cayman Islands exempted company (the “Company”),
and Cantor Fitzgerald & Co. as representative (the “Representative”) of the underwriters (each, an
 “Underwriter” and collectively, the “Underwriters”), relating to an underwritten initial
public offering (the “Public Offering”), of up to 23,000,000 of the Company’s units (including up to 3,000,000
units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one of the Company’s
Class A ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), and one-half of one redeemable
warrant. Each whole warrant (each, a “Warrant”) entitles the holder thereof to purchase one Ordinary Share at
a price of $11.50 per share, subject to adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement
on Form S-1 (File No. 333-253641) and prospectus (the “Prospectus”) filed by the Company with the
Securities and Exchange Commission (the “Commission”) and the Company shall apply to have the Units listed on
The Nasdaq Capital Market. Certain capitalized terms used herein are defined in Section 14 hereof.

 

In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, StoneBridge Acquisition Sponsor LLC, a Delaware limited liability
company (the “Sponsor”), and the undersigned individuals, each of whom is a member of the Company’s board
of directors and/or management team (each, an “Insider” and collectively, the “Insiders”),
hereby agree with the Company as follows:

 

1.              Proposed
Business Combination. The officer and directors of the Company will not enter into a binding
agreement for a proposed Business Combination or propose any Business Combination to shareholders of the Company unless such action is
first approved by the manager(s) of the Sponsor. Subject to the foregoing, the Sponsor and each Insider agrees that: (a) if
the Company seeks shareholder approval of a proposed Business Combination, then in connection with such proposed Business Combination,
it, he or she shall (i) vote any Shares owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem
any Shares owned by it, him or her in connection with such shareholder approval; (b) if the Company engages in a tender offer in
connection with any proposed Business Combination, it, he or she shall not sell any Shares to the Company in connection therewith; and
(c) if the Company seeks shareholder approval of any proposed amendment to the Charter prior to the consummation of a Business Combination,
it, he or she shall not redeem any Shares owned by it, him or her in connection with such shareholder approval.

 

    1

     

    

 

2.              Liquidation;
Charter Amendment; Trust Account Funds.

 

(a)              The
Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within the time period
set forth in the Charter, the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations
except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days thereafter, subject
to lawfully available funds therefor, redeem 100% of the Ordinary Shares sold as part of the Units in the Public Offering (the “Offering
Shares”), at a price per Ordinary Share, payable in cash, equal to the aggregate amount then on deposit in the Trust Account,
including interest earned on the funds held in the Trust Account and not previously released to the Company to pay any taxes (less up
to $100,000 of interest to pay dissolution expenses), divided by the number of then issued outstanding Offering Shares, which redemption
will completely extinguish all Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions,
if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval
of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in the case
of clauses (ii) and (iii) above to the Company’s obligations under Cayman Islands law to provide for claims of creditors
and other requirements of applicable law.

 

(b)              The
Sponsor and each Insider agrees to not propose any amendment to the Charter (i) that would affect the substance or timing of the
Company’s obligation to allow redemption in connection with the Business Combination or to redeem 100% of the Offering Shares if
the Company does not complete a Business Combination within the time period described in the Prospectus or (ii) with respect to any
other provision relating to shareholders’ rights or pre-Business Combination activity, unless the Company provides its Public Shareholders
with the opportunity to redeem their Ordinary Shares upon approval of any such amendment at a price per Ordinary Share, payable in cash,
equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and
not previously released to the Company to pay any taxes, divided by the number of then issued and outstanding Offering Shares.

 

(c)              The
Sponsor and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held in
the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held
by it, him or her. The Sponsor and each Insider hereby further waives any claim such Sponsor or Insider may have in the future as a result
of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the Trust Account for any reason
whatsoever except in each case with respect to the Insider’s right to a pro rata interest in the proceeds held in the Trust Account
for any Offering Shares such Sponsor or Insider may hold.

 

    2

     

    

 

3.              Section 16
Matters. During the period commencing on the effective date of the Underwriting Agreement
and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written consent of the Representative,
(a) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or
agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent
position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, Ordinary Shares, Founder Shares,
Private Placement Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or
her, (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences
of ownership of any Units, Ordinary Shares, Founder Shares, Private Placement Warrants or any securities convertible into, or exercisable,
or exchangeable for, Ordinary Shares owned by it, him or her, whether any such transaction is to be settled by delivery of such securities,
in cash or otherwise, or (c) publicly announce any intention to effect any transaction specified in clause (a) or (b). The Sponsor
and each Insider acknowledge and agree that, prior to the effective date of any release or waiver, of the restrictions set forth in this
Section 3 or Section 7 below, the Company shall announce the impending release or waiver by press release through
a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall
only be effective two business days after the publication date of such press release. The provisions of this Section 3 will
not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing
to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at
the time of the transfer.

 

4.              Trust
Account Liquidation. In the event of the liquidation of the Trust Account, the Sponsor (which
for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsor) agrees to indemnify and
hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any
and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or
threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (a) any third party for
services rendered or products sold to the Company or (b) a prospective target business with which the Company has entered into a
letter of intent, confidentiality or other similar agreement or a Business Combination agreement (a “Target”);
provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that
such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to
the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per Offering Share or (ii) such
lesser amount per Offering Share held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation
of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to
pay taxes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to
the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including
liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to be unenforceable against
such third party, the Sponsor shall not be responsible to the extent of any liability for such third party claims. The Sponsor shall have
the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following
written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

 

    3

     

    

 

5.              Forfeiture.
To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 3,000,000 Units within
45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number
of Founder Shares in the aggregate equal to 750,000 multiplied by a fraction, (a) the numerator of which is 3,000,000 minus the number
of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (b) the denominator of which is 3,000,000.
The Sponsor will be required to forfeit only that number of Founder Shares as is necessary so that the Sponsor and Insiders will own an
aggregate of 20.0% of the Company’s issued and outstanding equity shares after the Public Offering.

 

6.              Specific
Performance. The parties hereto agree and acknowledge that: (a) the Underwriters, the
Sponsor and the Company would be irreparably injured in the event of a breach by the applicable parties hereto of its, his or her obligations
under Section 1, Section 2, Section 3, Section 4, Section 5, Section 7(a),
Section 7(b), Section 8, Section 9, Section 10, and Section 13, as applicable, of
this Letter Agreement (b) monetary damages may not be an adequate remedy for such breach and (c) the non-breaching party shall
be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

 

7.              Lock-Up
Restrictions.

 

(a)              The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or Ordinary Shares issuable upon conversion
thereof) until the earlier of (i) one year after the completion of the Company’s initial Business Combination or (ii) subsequent
to the initial Business Combination, (x) if the last sale price of the Ordinary Shares equals or exceeds $12.00 per Ordinary Share
(as adjusted for share splits, share consolidations, share capitalizations, rights issuances, subdivisions, reorganizations, recapitalizations
and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial
Business Combination or (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other
similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash,
securities or other property (the “Founder Shares Lock-up Period”).

 

(b)              The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (and the Ordinary Shares issuable
upon their exercise), until 30 days after the completion of the Company’s initial Business Combination (the “Private
Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 

    4

     

    

 

(c)              Notwithstanding
the provisions set forth in Sections 7(a) and Sections 7(b), Transfers of the Founder Shares, Private Placement Warrants
or the Ordinary Shares issued or issuable upon the conversion of the Private Placement Warrants or the Founder Shares and that are held
by the Sponsor, any Insider or any of their permitted transferees (that have complied with this Section 7(c)), are permitted
(i) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors,
any members of the Sponsor, or any affiliates of the Sponsor; (ii) in the case of an individual, transfers by gift to a member of
the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or
an affiliate of such person, or to a charitable organization; (iii) in the case of an individual, transfers by virtue of laws of
descent and distribution upon death of the individual; (iv) in the case of an individual, transfers pursuant to a qualified domestic
relations order; (v) transfers by private sales or transfers made in connection with any forward purchase agreement or similar arrangements
or in connection with the consummation of a Business Combination at prices no greater than the price at which the securities were originally
purchased; (vi) transfers in the event of the Company’s liquidation prior to the completion of an initial Business Combination;
and (vii) transfers by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon
dissolution of the Sponsor; provided, however, that in the case of clauses (i) through (v) or (vii), these permitted transferees
must enter into a written agreement agreeing to be bound by the restrictions herein and by the same agreements entered into by the Sponsor
with respect to such securities (including provisions relating to voting, the trust account and liquidation distributions).

 

8.              Director
and Officer Appointments. Each of the Insiders agrees to be a director or officer of the
Company, as applicable, until the earlier of the consummation by the Company of an initial Business Combination, the liquidation of the
Company, or his or her removal, death or incapacity. In the event of the removal or resignation of an Insider as a director or officer
(as applicable), each Insider agrees that he or she will not, prior to the consummation of the Business Combination, without the prior
express written consent of the Company, (a) use for the benefit of the undersigned or to the detriment of the Company or (b) disclose
to any third party (unless required by law or governmental authority), any information regarding a potential Target that is not generally
known by persons outside of the Company, the Sponsor, or their respective affiliates.

 

9.              Approval
of Business Combination. Subject to Section 1, each of the undersigned acknowledges
and agrees that prior to entering into a definitive agreement for a Business Combination with a Target that is affiliated with the Sponsor,
any of the Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested
directors and the Company must obtain an opinion from an independent investment banking firm, another independent entity that commonly
renders valuation opinions for the type of company the Company is seeking to acquire, or an independent accounting firm, that such Business
Combination is fair to the Company from a financial point of view.

 

10.            Representation
and Warranties. The Sponsor and each Insider represents and warrants that it, he, or she
has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities
license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company (including
any such information included in the Prospectus) is true and accurate in all respects and does not omit any material information with
respect to the Insider’s background. Each Insider’s questionnaire furnished to the Company is true and accurate in all respects.
Each Insider represents and warrants that it, he or she: (a) is not subject to or a respondent in any legal action for, any injunction,
cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in
any jurisdiction; (b) has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to
any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it or
he is not currently a defendant in any such criminal proceeding.

 

    5

     

    

 

11.           No
Insider Payments. Except as disclosed in the Prospectus, neither the Sponsor, nor any Insider,
nor any affiliate of either the Sponsor or any Insider, nor any director or officer of the Company, shall receive from the Company any
finder’s fee, reimbursement or cash payments prior to or in connection with any services rendered in order to effectuate the consummation
of the Company’s initial Business Combination (regardless of the type of transaction that it is), other than the amounts described
in the Prospectus under the heading “Summary – The Offering – Limited Payments to Insiders.”

 

12.           Authority
and Capacity. The Sponsor and each Insider has full right and power, without violating any
agreement to which it is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or
former employer), to enter into this Letter Agreement and, as applicable, to serve as an officer and/or director on the board of directors
of the Company and hereby consents to being named in the Prospectus as an officer and/or director of the Company.

director of the Company.

 

(c)               In
the event that any Sponsor Representative is unable for any reason including lack of qualifications or refusal to serve as a director,
then the Sponsor shall be entitled to name a new nominee to fill such position and the directors of the Company will, in accordance with
the Charter, appoint that Sponsor Representative to the board of directors of the Company as a director of the Company.

 

(d)              The
Company agrees that the Sponsor Representative shall be indemnified by the Company for his or her conduct as a director to the same extent
and in the same manner as the current and other directors of the Company are currently indemnified and shall be included on the policy
of directors and officers insurance to the same extent as all other directors.

 

(e)               Each
of the Insiders acknowledges and agrees not to take any action resulting in the Company incurring, accruing or being obligated to any
expenditure of $50,000 or greater, without the prior written consent of the Sponsor Representative.

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

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

NOW THEREFORE, IT IS AGREED:

 

1.             Agreements

or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated

(i)             Commence

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)

    2

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
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;

 

    5 

     

    

 

(g)             Verify
the accuracy of the information contained in the Registration Statement;

 

(h)             Provide
any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as contemplated by
the Registration Statement;

 

(i)             File
information returns with respect to the Trust Account with any local, state or federal taxing authority or provide periodic written statements
to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property;

 

(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
1(k)hereof.

 

4.             4Trust
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.

 

5.             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, 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.

 

(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
to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained

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

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. 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,

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.
