WHEREAS, the Company’s registration statement on Form S-1, No. 333-276857 (the “Registration Statement”), for its initial public offering of Company’s units (the “Units”), each of which consists of one Class A ordinary shares, par value $0.0001 per share (the “Class A ordinary shares”), and one right to receive one-fifth (1/5) of one Class A ordinary share upon the consummation of the Company’s initial business combination (such initial public offering hereinafter referred to as the “Offering”); and

WHEREAS, the Company has entered into an Underwriting Agreement (the “Underwriting Agreement”) with EF Hutton LLC, (the “Representative”) acting as the representative of the underwriters in the Offering; and

WHEREAS, simultaneously with the Offering, Black Hawk Management LLC, the Company’s sponsor will be purchasing 235,500 (or 251,025 if the overallotment is exercised in full) private units (“Private Placement Units”) at $10.00 per private unit (for a total purchase price of $2,355,000 or $2,510,250 if the overallotment is exercised in full); and

WHEREAS, as described in the Registration Statement $71,355,500 of the gross proceeds of the Offering and sale of the Private Placement Units ($81,860,250 if the underwriters’ over-allotment option is exercised in full) will be delivered to the Trustee to be deposited and held in a trust account located at all times in the United States (the “Trust Account”) for the benefit of the Company and the holders of Class A ordinary shares included in the Units issued in the Offering as hereinafter provided (the amount to be delivered to the Trustee will be 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”); and

WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $2,415,000, or $2,777,250 if the underwriters’ over-allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that may become payable by the Company to the underwriters upon the consummation of an initial business combination (as described in the Registration Statement, a “Business Combination”); 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 a segregated trust account (“Trust Account”) established by the Trustee at JP Morgan Chase Bank, NA (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) in the United States, maintained by Trustee, and at a brokerage institution selected by the Trustee that is reasonably satisfactory to the Company;

(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, either (i) invest and reinvest the Property solely 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, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act (or any successor rule), which invest only in direct U.S. government treasury obligations or (ii) deposit the Property into an interest bearing or non-interest bearing bank 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, as determined by the Company; it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder and while the account funds are invested or uninvested, the Trustee may earn bank credits or other consideration during such periods.

(d) Collect and receive, when due, all principal and 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 it with respect to any Property requiring action by the Company;

(f) Supply any necessary information or documents as may be requested by the Company in connection with the Company’s preparation of its tax returns;

(h) Render to the Company monthly written statements of the activities of and amounts in the Trust Account reflecting all receipts and disbursements of the Trust Account; and

(i) Commence liquidation of the Trust Account only after and promptly after receipt of, and only in accordance with, the terms of a letter (“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 its Chief Executive Officer or Chairman of the board of directors (the “Board”), and in the case of Exhibit A, jointly signed by the Representative, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account only as directed in the Termination Letter and the other documents referred to therein; provided, however, that in the event that a Termination Letter has not been received by the Trustee by the 15-month anniversary of the closing of the Offering (“Closing”) or, in the event that the Company extends the time to complete the Offering for up to 18 or 21 months from the closing of the Offering (each, an “Applicable Deadline”), the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including interest (which interest shall be net of any taxes payable and less up to $50,000 of interest to pay dissolution expenses), shall be distributed to the Public Shareholders of record as of such date;

(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, withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover certain tax obligations owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority, as applicable; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution so long as there is no reduction in the principal amount per share initially deposited in the Trust Account. The Company is not permitted to use the proceeds placed in the trust account and the interests earned thereon to pay any excise taxes or any other similar fees or taxes in nature that may be imposed on the Company pursuant to any current, pending or future rules or laws. The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request;

(l) Not disburse any amounts from the Trust Account in connection with a Business Combination in the event that the amount per share to be received by the redeeming Public Shareholders is less than $10.00 per share (plus the amount per share deposited in the Trust Account pursuant to any Extension Letter).

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;

(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.
