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 among Sieger Healthcare Acquisition Corp, a Cayman Islands exempted company (the “Company”), Piper
Sandler & Co., as the representative of the underwriter (the “Representative”), relating to an underwritten
initial public offering (the “Public Offering”) of 8,625,000 of the Company’s units (including up to
1,125,000 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 (“Ordinary Shares”), and one-third
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 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange
Commission (the “Commission”) and the Company has applied to have the Units listed on the NASDAQ. Certain capitalized
terms used herein are defined in paragraph 11 hereof.

 

In order to induce the Company and the Representative 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, Sieger Healthcare LLC, a Cayman Islands limited liability company (the
 “Sponsor”), and each of the undersigned individuals, each of whom is a member of the Company’s board
of directors (the “Board”) and/or management team and/or Senior Advisor (each, an
 “Insider” and collectively, the “Insiders”), hereby agrees, jointly and
severally, with the Company as follows:

 

1. The Sponsor and each Insider agrees with the Company that 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 of Shares owned by it, him or her in favor of the proposed Business Combination (including any
proposals recommended by the Board in connection with such Business Combination) and (ii) not redeem any Shares owned by it, him
or her in connection with such shareholder approval.

 

2. The Sponsor and each Insider hereby agrees that in the event that
the Company fails to consummate a Business Combination within the period of time set forth in the Company’s amended and restated
memorandum and articles of association, as the same may be further amended, supplemented or otherwise modified from time to time, , or
such later period approved by the Company’s shareholders in accordance with the Company’s second amended and restated memorandum
and articles of association, 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,
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 (less up to $75,000 of interest
to pay dissolution expenses), including interest earned on the funds held in the Trust Account and not previously released to the Company
to pay the Company’s taxes, 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), and
(iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders
and the Board, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for
claims of creditors and other requirements of applicable law. The Sponsor and each Insider agree to not propose any amendment to the
Company’s second amended and restated memorandum and articles of association (i) to modify the substance or timing of the
Company’s obligation to allow redemption in connection with a Business Combination or to redeem 100% of the Offering Shares if
the Company does not complete a Business Combination within the period of time set forth in the Company’s amended and restated
memorandum and articles of association, as the same may be further amended, supplemented or otherwise modified from time to time, 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 the Company’s taxes, divided by the number
of then outstanding Offering Shares.

 

    1

    

    

 

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
waive, with respect to any Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with (x) the
consummation of a Business Combination, including, without limitation, any such rights available in the context of a shareholder vote
to approve such Business Combination or in the context of a tender offer made by the Company to purchase Ordinary Shares and (y) a
shareholder vote to amend the Company’s second amended and restated memorandum and articles of association (i) to modify the
substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or to redeem 100%
of the Offering Shares if the Company does not complete a Business Combination within the period of time set forth in the Company’s
amended and restated memorandum and articles of association, as the same may be further amended, supplemented or otherwise modified from
time to time, or (ii) with respect to any other provision relating to shareholders’ rights or pre-Business Combination activity
(although the Sponsor, the Insiders and their respective affiliates shall be entitled to redemption and liquidation rights with respect
to any Offering Shares it or they hold if the Company fails to consummate a Business Combination within the time period set forth therein).

 

3. 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,
(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 (including, but not limited
to, Founder Shares), Warrants 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 (including, but not limited to, Founder Shares), 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 (iii) publicly announce any intention to effect any transaction specified in clause (i)
or (ii). Each of the Sponsor and the Insiders acknowledges and agrees that, prior to the effective date of any release or waiver, of
the restrictions set forth in this paragraph 3 or paragraph 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 paragraph
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 upon the failure
of the Company to consummate its Initial Business Combination within the time period set forth in the Company’s second amended
and restated memorandum and articles of association, the Sponsor (which for purposes of clarification shall not extend to any other shareholders,
members, managers, or any other affiliates 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 (other than the Company’s independent accountants)
for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has discussed
entering, or entered, into a letter of intent, confidentiality or other similar agreement for a Business Combination (a “Target”);
provided, however, with respect to claims described in (i) and (ii) above, 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. Such liability will not apply 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 nor will it apply to any claims
under the Company’s indemnity of the Underwriter against certain liabilities, including liabilities under the Securities Act of
1933, as amended, pursuant to the Underwriting Agreement. 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. For the avoidance of doubt, none of the Company’s officers or directors will indemnify the Company for claims by
third parties, including, without limitation, claims by vendors and prospective Targets.

 

5. To the extent that the Underwriter do not exercise their
over-allotment option to purchase up to an additional 1,125,000 Units within 45 days from the date of the Prospectus (and as further
described in the Prospectus), the Sponsor, the chief executive officer and the chief financial officer named in the Prospectus
agrees to forfeit, at no cost, a number of Founder Shares in the aggregate equal to the product of 281,250 multiplied by a fraction,
(i) the numerator of which is 1,125,000 minus the number of Units purchased by the Underwriter upon the exercise of their
over-allotment option, and (ii) the denominator of which is 1,125,000. All references in this Letter Agreement to Shares of the
Company being forfeited shall take effect as surrenders for no consideration of such Shares as a matter of Cayman Islands law. The
forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriter so that the
number of Founder Shares will equal an aggregate of 20.0% of the sum of the Company’s issued and outstanding Shares upon the
consummation of the Public Offering plus 1,500,000 Class A ordinary shares of the Company to be sold pursuant to the forward
purchase agreements.

 

Prior to the Public Offering, the Company entered into forward purchase
agreements pursuant to which certain investors (the “Forward Purchasers”) agreed to subscribe for an aggregate of 1,500,000
Class A ordinary shares plus 500,000 redeemable warrants for a purchase price of $10.00 multiplied by the number of Class A ordinary
shares, or $15,000,000 in the aggregate, in a private placement to close concurrently with the closing of the initial Business Combination.
In connection with entering into these agreements, the Sponsor was issued an aggregate of 375,000 Founder Shares and transferred to the
Forward Purchasers an aggregate of 150,000 of such Founder Shares for no cash consideration. To the extent that the Forward Purchasers
fail to close on their obligation to purchase forward purchase securities at the time of the initial Business Combination, the Sponsor
agrees that it shall forfeit, at no cost, the incremental 225,000 shares or such lesser number of shares in order to maintain the 20.0%
ratio of the Class B ordinary shares (prior to giving effect to their conversion at closing of the initial Business Combination) against
the total number of the Company’s issued and outstanding Shares after the Public Offering.

 

6. The Sponsor and each Insider hereby agrees and acknowledges that:
(i) the Underwriter and the Company would be irreparably injured in the event of a breach by such Sponsor or an Insider of its,
his or her obligations under paragraphs 1, 2, 3, 4, 5,7(a), 7(b), and 9 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.

 

    3

    

    

 

7. (a) The Sponsor and each Insider agree that it, he or she
shall not Transfer any Founder Shares (or Ordinary Shares issuable upon conversion thereof) until the earlier of (A) one year after
the completion of the Company’s initial Business Combination and (B) subsequent to the Business Combination, (x) if the
last reported sale price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share capitalizations,
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 agree that it, he or she shall not
Transfer any Private Placement Warrants (or Ordinary Shares issued or issuable upon the exercise of the Private Placement Warrants) until
30 days after the completion of a Business Combination (the “Private Placement Warrants Lock-up Period”, together
with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 

(c) Notwithstanding the provisions set forth in paragraphs 7(a) and
(b), Transfers of the Founder Shares, Private Placement Warrants and Ordinary Shares issued or issuable upon the exercise or 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 paragraph 7(c)), are permitted (a) 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 of their respective affiliates;
(b) in the case of an individual, 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; (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) by private sales or transfers made in connection with the consummation of
a Business Combination at prices no greater than the price at which the securities were originally purchased; (f) to a nominee or
custodian holding securities on behalf of a beneficial owner to whom a disposition or transfer would be permissible under clauses (a) through
(e) above; (g) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (h) by
virtue of the laws of the Cayman Islands or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor;
and (i) in the event of the Company’s liquidation, merger, share exchange, reorganization or other similar transaction which
results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property
subsequent to the completion of the Company’s initial Business Combination; provided, however, that in the case of clauses (a) through
(f), these permitted transferees must enter into a written agreement with the Company agreeing to be bound by the restrictions in this
Agreement (including provisions relating to voting, the Trust Account and liquidating distributions).

 

8. The Sponsor and each Insider represent and warrant 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

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, he or she is not currently a defendant in any such criminal proceeding.

 

9. Except as disclosed in or expressly contemplated by the Prospectus,
neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider, nor any director or officer of the Company, shall
receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other
compensation prior to, or in connection with any services rendered in order to effectuate the consummation of a Business Combination
(regardless of the type of transaction that it is).

 

10. The Sponsor and each Insider have 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 a director on the
board of directors of the Company and hereby consents to being named in the Prospectus, road show and any other materials as the Sponsor,

WHEREAS, the Company’s registration statement on Form S-1,
File No. 333-[•] (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 of
the Company’s Class A ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), and one-third
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; and

 

WHEREAS, the Company has entered into an Underwriting Agreement (the
 “Underwriting Agreement”) with Piper Sandler & Co. as the representative (the “Representative”)
to the underwriter (the “Underwriter”) named therein;

 

WHEREAS, if a Business Combination (as defined herein) is not consummated
within the initial 18 month period following the closing of the Offering, upon the request of the Company’s sponsor (the “Sponsor”),
the Company may extend such period up to six times, each by an additional one month for a total of up to 24 months (the “Paid
Extension Period”), to complete a Business Combination. In order to avail itself of the Paid Extension Period to consummate
a Business Combination, the Sponsor or its affiliates or permitted designees, upon five days advance notice prior to the applicable monthly
deadline (each, the “Applicable Deadline”), shall deposit $250,000 (or
$287,500 if the Underwriters’ over-allotment option is exercised in full) into the Trust Account (as defined below) on or
prior to the date of the Applicable Deadline for each one month extension (each, an “Extension”), in exchange
for which the Sponsor will receive a non-interest bearing, unsecured promissory note for each Extension payable upon consummation of
a Business Combination;

 

WHEREAS, as described in the Prospectus, $75,000,000 of the gross proceeds
of the Offering and sale of the Private Placement Warrants (as defined in the Underwriting Agreement) (or $86,250,000 if the Underwriter’s
option to purchase additional units is exercised in full) and the proceeds from any loan in connection with an Extension 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 $2,625,000, or $3,018,750 if the Underwriter’s option to purchase additional units is exercised in full, is attributable
to deferred underwriting discounts and commissions that will be payable by the Company to the Underwriter upon 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

by the Trustee that is reasonably satisfactory to the Company;

 

    1

successor rule), which invest only in direct U.S. government treasury obligations, as determined by the Company; the Trustee may not invest
in any other securities or assets, it being understood that the Trust Account will earn no interest while account funds are uninvested
awaiting the Company’s instructions hereunder; while the account funds are invested or uninvested, 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

except with respect to its duties under Sections 1(i), (j) or (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

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), it shall notify the Company in writing of such claim (an “Indemnified Claim”).
The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall

(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

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 Underwriter prior to any transfer of the funds held in the Trust Account to the Company or any other person;

 

    3

     

    

 

(g) Instruct the Trustee to make only those distributions that

Agreement;

 

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

its option to purchase additional units (or any unexercised portion thereof) or such option to purchase additional units expires, provide
the Trustee with a notice in writing of the total amount of the Deferred Discount.

 

(j) If applicable, issue a press release at least three days prior

Sponsor that the Sponsor intends to deposit funds into the Trust Account for extending the Applicable Deadline and the Board has approved
such Extension.

(g) 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;

by the Company, if any, relating to any interest income earned on the Property;

 

(k) 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

or

 

(l) 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.

 

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. 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 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 in the information or transmission of the
funds.

 

    5

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

consummate a business combination with Target Business (the “Business Combination”) on or about [insert date].
The Company shall notify you at least seventy-two (72) hours in advance of the actual date (or such shorter time period as you may
agree) of the consummation of the Business Combination (the “Consummation Date”). Capitalized terms used but
not defined herein shall have the meanings set forth in the Trust Agreement.

 

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

 

On the Consummation Date (i) counsel for the Company shall deliver
to you written notification that the Business Combination has been consummated, or will be consummated substantially concurrently with
your transfer of funds to the accounts as directed by the Company (the “Notification”), and (ii) the Company
shall deliver to you (a) a certificate of the Chief Executive Officer, Chief Financial Officer or other authorized officer of the
Company, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders, if a vote is held
and (b) joint written instruction signed by the Company and the Representative with respect to the transfer of the funds held in
the Trust Account, including payment of the Deferred Discount 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.

 

In the event that the Business Combination is not consummated on the
Consummation Date described in the notice thereof and the Company 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.
