WHEREAS, the Company’s registration statement on Form S-1 (File No. 333-280564) (the “Registration Statement”) and prospectus (the “Prospectus”) for the initial public offering (the “Offering”) of the Company’s units (the “Units”), each of which consists of one ordinary share, par value $0.0001 per share (the “Shares”), and one right entitling the holder thereof to receive one-tenth of one Share upon the completion of an initial Business Combination (as defined below), 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 EarlyBirdCapital, Inc., as representative (the “Representative”) of the several underwriters (the “Underwriters”) named therein;

WHEREAS, if a Business Combination is not consummated within the initial 12 month period following the closing of the Offering, the Company may extend such period by up to three times each for a three month extension (an “Extension”) for up to a maximum of 21 months in the aggregate, subject to the Company’s sponsors, Yawei Cao and Cayson Holding LP (collectively, the “Sponsors”) or their affiliates or permitted designees depositing $0.10 per share outstanding on such date no later than the 12-month anniversary of the Offering for the first three-month Extension, no later than the 15-month anniversary of the Offering for the second three-month Extension and no later than the 18-month anniversary of the Offering for the third three-month Extension, in exchange for which the Sponsors will be issued a non-interest bearing, unsecured promissory note for each Extension that will be repaid only if the Company completes a Business Combination by the end of the applicable Extension or otherwise has funds available to it outside of the Trust Account (as defined below); and

WHEREAS, as described in the Prospectus, $60,000,000 of the gross proceeds of the Offering and sale of the Private Placement Units (as defined in the Underwriting Agreement) (or $69,000,000 if the Underwriters’ over-allotment option is exercised in full) will be delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United States (the “Trust Account”) for the benefit of the Company, the holders of the Shares included in the Units issued in the Offering and the Underwriters 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, the Company and the Underwriters will be referred to together as the “Beneficiaries”); and

WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $2,100,000, or $2,415,000 if the Underwriters’ over-allotment option is exercised in full, is attributable to deferred underwriting commissions that will be payable by the Company to the Representative upon and concurrently with the consummation of the Business Combination (as defined below) (the “Deferred Fee”); and

WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property.

NOW THEREFORE, IT IS AGREED:

1. Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to:

(a) Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the Trustee in the United States at JPMorgan Chase Bank, N.A.

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

(c) In a timely manner, upon the written instruction of the Company, (i) invest and reinvest the Property in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), having a maturity of 185 days or less, and/or in any open ended investment company registered under the Investment Company Act that holds itself out as a money market fund selected by the Company meeting the conditions of paragraph (d) of Rule 2a-7 promulgated under the Investment Company Act, which invest only in direct U.S. government treasury obligations or (ii) deposit the Property into an interest bearing or non-interest bearing demand deposit account at a U.S. chartered commercial bank with consolidated assets of $100 billion or more selected by the Trustee that is reasonably satisfactory to the Company; it being understood that unless the Company instructs the Trustee to do either of the foregoing, the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder; and while funds are uninvested or invested, the Trustee may earn bank credits or other consideration during such periods;

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

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

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

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 documented 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 it is distributed to the Company pursuant to Sections 1(i) through 1(k) 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 or entities (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;

(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

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 to any third party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct;

(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 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;

(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.

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 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 will each restrict access to confidential information relating to funds being transferred to or from the Trust Account 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 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 fraud, gross negligence or willful misconduct, the Trustee shall not be liable for any loss, liability, or expense resulting from any error in the information supplied to it or funds transferred based on such information.

(b) This 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. The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, Borough of Manhattan, for purposes of resolving any disputes hereunder. As to any claim, cross-claim, or counterclaim in any way relating to this Agreement, each party waives the right to trial by jury.

(c) This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for Section 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or deleted without the affirmative vote of fifty percent (50%) of the then outstanding Shares; provided that no such amendment will affect any Public Shareholder who has properly elected to redeem his or her Shares in connection with a shareholder vote 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; provided, however, that no such change, amendment or modification to Section 1(i) or 2(f) or Exhibit A may be made without the prior written consent of the Representative.

(d) The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.
