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 Hainan Manaslu Acquisition Corp., a Cayman Islands exempted company (the “Company”),
and Ladenburg Thalmann & Co., Inc., as representative (the “Representative”) of the several underwriters
(each, an “Underwriter” and collectively, the “Underwriters”), relating to an underwritten
initial public offering (the “Public Offering”) of up to 6,900,000 of the Company’s units (including up
to 900,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one
ordinary share of the Company, par value $0.0001 per share (the “Ordinary Shares”), and one redeemable warrant,
and one right to receive one-tenth of one Ordinary Share (the “Rights”). Each warrant (the “Warrant”)
entitles the holder thereof to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustments as described in the
Prospectus (as defined below). The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 (File
No. 333-261340) and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange
Commission (the “Commission”), and the Company shall apply to have the Units listed on the Nasdaq Global Market.
Certain capitalized terms used herein are defined in Section 11 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, Bright Winlong LLC (the “Sponsor”)
and the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team, hereby agree
with the Company as follows:

 

1. 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 or tender 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.

 

2. Each Insider hereby agrees that, in the event
that the Company fails to consummate a Business Combination within 9 months (or up to a maximum of 18 months if such date is extended
as described in the Prospectus) after the closing of the Public Offering, or such later period approved by the Company’s shareholders
in accordance with the Charter, 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 ten (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 per-share price, 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 $60,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will
completely extinguish all Public Shareholders’ rights as shareholders (including the right to receive further liquidation 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. 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 provide holders of the Offering Shares the right to have their Offering Shares redeemed in
connection with the Business Combination or 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 Offering
Shares upon approval of any such amendment at a per-share price, 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
its taxes, divided by the number of then outstanding Offering Shares.

 

    

     

    

 

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 and the Placement Shares held by it, him or her.
Each Insider hereby further waives any claim such 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 Insider may hold.

 

3. During the period commencing
on the effective date of the Underwriting Agreement and ending one hundred eighty (180) days after such date, each Insider shall not,
without the prior written consent of the Representative, (i) 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, Warrants, Rights or any securities convertible into, or exercisable, or exchangeable
for, Ordinary Shares owned by it, him or her, (ii) 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, Warrants, Rights 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 (iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii). Each of the Insiders acknowledges and agrees that, prior to the effective date of any release or
waiver of the restrictions set forth in this Section 3, the Company shall announce the impending release or waiver by press release
through a major news service at least two (2) business days before the effective date of the release or waiver. Any release or waiver
granted shall only be effective two (2) business days after the publication date of such press release. The provisions of this Section
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. 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 (i) any
third party for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has
entered into a written 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 or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below
(i) $10.15 per share of the Offering Shares or (ii) such lesser amount per share of the Offering Shares 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 (the “Securities Act”). 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.

 

5. To the extent that
the Underwriters do not exercise their over-allotment option to purchase up to an additional 900,000 Units within forty five (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 225,000 multiplied by a fraction, (i) the numerator of which is 900,000 minus the number of Units
purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 900,000. The
forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Founder
Shares will represent an aggregate of 20% of the Company’s issued and outstanding Ordinary Shares after the Public Offering (not
including Placement Shares).

 

    2

     

    

 

6. Each Insider hereby
agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such
Insider of its, his or her obligations under Sections 1, 2, 3, 4, 5, 7(a), 7(b), and
9, as applicable, of this Letter Agreement; (ii) monetary damages may not be an adequate remedy for such breach; and (iii) 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. (a) Subject to
Section 7(c), each Insider agrees that, with respect to 50% of the Founder Shares, it, he or she shall not Transfer any of such
Founder Shares until the earlier of (A) six months after the completion
of the Company’s initial Business Combination or (B) subsequent to the Business Combination, if the last sale price of the Ordinary
Shares equals or exceeds $12.50 per share (as adjusted for share splits,
share capitalizations, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any twenty (20) trading days
within any thirty (30)-trading day period commencing after the Company’s initial Business Combination; and with respect to the remaining
50% of the Founder Shares, it, he or she shall not Transfer any of such Founder Shares until the earlier of (x) six months
after the date of the consummation of the Company’s initial Business Combination, or (y) subsequent to the Company’s initial
Business Combination, 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) Subject to Section
7(c), each Insider agrees that it, he or she shall not Transfer any Placement Units, Working Capital Units (as defined in the Registration
Rights Agreement), Extension Loan Units (as defined in the Registration Rights Agreement), and their respective underlying securities
until thirty (30) days after the completion of a Business Combination (the “Placement Unit Lock-up Period”,
together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 

(c) Notwithstanding the
provisions set forth in Sections 7(a) and (b), Transfers of the Founder Shares, the Placement Units, the Working Capital
Units, the Extension Loan Units, and their respective underlying securities that are held by any Insider or any of their permitted transferees
(that have complied with this Section 7(c)), are permitted (1) (a) to the Sponsor’s officers or directors, any affiliates
or family members of the Sponsor or any of the Company’s officers or directors, any members of the Sponsor, or any affiliates of
the Sponsor; (b) in the case of an individual, by gift to a member of the individual’s immediate family, or to a trust, the beneficiary
of which is a member of one of the individual’s immediate family, or an affiliate of such person, or to a charitable organization;
(c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual,
pursuant to a qualified domestic relations order; (e) in the event of the Company’s liquidation prior to the completion of an initial
Business Combination; or (f) by virtue of the laws of the Cayman Islands or the Sponsor’s organizational documents upon dissolution
of the Sponsor; provided, however, that in each case these permitted transferred must enter into a written agreement agreeing to be bound
by these transfer restrictions and by the same agreements entered into by the Sponsor with respect to such securities; and (2) in connection
with an initial Business Combination with the consent of the Company to any third party that agrees in writing to be bound by the provisions
of this Letter Agreement applicable to Insiders (other than paragraph 1). For the avoidance of doubt, for the purposes of this Letter
Agreement, a managed account managed by the same investment manager of any member of the Sponsor shall be deemed an affiliate of such
member.

 

(d) Subject to the limitations
described herein, each Insider shall retain all of such Insider’s rights as a security holder during, as applicable, the Lock-up
Periods including, without limitation, the right to vote, as the case may be, the Founder Shares and/or Placement Shares.

amounts described in the Prospectus under the heading “Summary – The Offering – Limited Payments to Insiders.”

interest earned on the Trust Account, less interest previously released to, or reserved for use by, the Company in an amount up to $60,000
to pay dissolution expenses (as applicable) and less any other interest released to, or reserved for use by, the Company to pay taxes,
shall be distributed to the Public Shareholders of record as of such date. The Trustee agrees to serve as the paying agent of record (“Paying
Agent”) with respect to any distribution of Property that is to be made to the Public Shareholders and, in its separate
capacity as Paying Agent, agrees to distribute such Property directly to the Company’s Public Shareholders in accordance with the
terms of this Agreement and the Company’s amended and restated memorandum and articles of association in effect at the time of such
distribution;

 

    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 (a
“Withdrawal Request”), withdraw from the Trust Account and distribute to the Company interest in an amount up
to $60,000 to pay dissolution expenses and any interest to cover any tax obligation owed by the Company as a result of assets of the Company
or any taxes of the Company 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. To the extent there is not sufficient cash in the
Trust Account to fulfill a Withdrawal Request, 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 per share initially deposited
in the Trust Account. The Trustee acknowledges and agrees that no amount in excess of interest income earned on the Property shall be
payable from the Trust Account to the Company pursuant to this Section 1(j). A Withdrawal Request 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 (i) to modify the substance or timing of the Company’s obligation to provide holders of Ordinary
Shares the right to have their Ordinary Shares redeemed in connection with an initial Business Combination or to redeem 100% of the Ordinary
Shares included in the Units sold in the Offering if the Company has not consummated an initial Business Combination within such time
as is described in Section 1(i) of this Agreement or (ii) with respect to the other provisions relating to shareholders’
rights or pre-Business Combination activity. 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;

 

(l) Not make any withdrawals
or distributions from the Trust Account other than pursuant to Sections 1(i) through 1(k) above; and

 

(m) Upon receipt of an extension
letter (“Extension Letter”) substantially similar to Exhibit E hereto prior to the Applicable
Deadline, signed on behalf of the Company by an executive officer, and receipt of the dollar amount specified in the Extension Letter
on or prior to the Applicable Deadline, follow the instructions set forth in the Extension Letter.

 

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, President, Chief Executive Officer or Chief Financial
Officer. 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;

 

(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), the Trustee 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 shall 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;

 

    3

     

    

 

(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

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 (a “Business Combination”), provide to the Trustee
an affidavit or certificate of the inspector of elections for the general 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) 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;

 

(g) Within four (4) business
days after the Underwriters exercise the over-allotment option (or any portion thereof) or such over-allotment option expires, provide
the Trustee with a notice in writing of the total amount of the Deferred Discount due with respect to such exercise, which shall be up
to $2,242,500;

 

(h) 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;

 

(i) If applicable, issue a press
release at least three days prior to the Applicable Deadline announcing that, at least five days prior to the Applicable Deadline, the
Company received notice from the Sponsor that the Sponsor intends to deposit funds into the Trust Account for extending the Applicable
Deadline and the Board has approved such Extension; and

 

(j) Promptly following the Applicable
Deadline, disclose whether or not the deadline for the Company to consummate a Business Combination has been extended.

 

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;

in principal of any Property;

 

    4

     

    

 

(e) Assume that the authority

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

tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and activities relating to, the Trust

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. 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
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.

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 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

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) and
distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except as set forth
in Section 2(b).

 

    5

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

	 	Re:	Trust Account  - Termination Letter

 

Dear Mr. Wolf and Mr. Egan:

 

Pursuant to Section
1(i) of the Investment Management Trust Agreement between Hainan Manaslu Acquisition Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of [•], 2022 (the “Trust

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 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 a segregated account at J.P. Morgan Chase Bank, N.A. held by you on behalf of the Beneficiaries so that, on the Consummation Date,
all of 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 segregated account at JPMorgan 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 by the Chief Executive Officer, President, Chief Financial Officer, Executive
Vice President, Vice President, Secretary or Chairman, 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 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 from the Trust
Account, your obligations under the Trust Agreement shall be terminated.

 

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 such notice as soon thereafter as possible.
