terms of, a letter from the Company (“Termination Letter”) in a form substantially similar to that attached
hereto as either Exhibit A or Exhibit B, as applicable, signed on behalf of the Company by an Authorized Representative

Letter and other documents referred to therein, or (y) upon the date which is the later of (1) 18 months after the closing of
the Offering and (2) such later date as may be approved by the Company’s stockholders in accordance with the Company’s

funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority, as applicable;
provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the

that if the tax to be paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a
copy of the franchise tax bill from the State of Delaware for the Company and a written statement from the principal financial officer
of the Company setting forth the actual amount payable (it being acknowledged and agreed that any such amount in excess of interest income

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 out-of-pocket expenses, including
reasonable outside counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder

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 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”), provided, that no failure or delay by the Trustee
to so notify the Company shall relieve the Company from its obligations under this Agreement, except as and to the extent it is found,
in a final, unappealable judgment by a court of competent jurisdiction, that such failure or delay actually and materially prejudiced
the Company. 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 or
delayed. 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 or delayed. The Company may participate in such action with its own counsel and at its sole cost and
expense;

hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation of
the Offering. 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;

 “Business Combination”), provide to the Trustee an affidavit or certificate of the inspector of elections for
the stockholder meeting verifying the vote of such stockholders regarding such Business Combination;


 


(e) Provide

provide in any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination Letter in the Form of Exhibit A

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

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).

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 on [insert date], and
to transfer proceeds to the account of the paying agent specified by the Company 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 US Tiger Securities. (the

concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”) and

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 Business Combination Fee 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.
