WHEREAS, Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC and BofA Securities, Inc. are acting as the representatives (the “Representatives”) of the underwriters (the “Underwriters”) in the Offering pursuant to an underwriting agreement among the Company and the Underwriters (“Underwriting Agreement”);

WHEREAS, simultaneously with the Offering, the Company’s sponsor will be purchasing 14,666,667 warrants (“Private Placement Warrants”) from the Company for an aggregate purchase price of approximately $22,000,000 (and additional amounts of Private Placement Warrants from the Company if the Underwriters exercise their over-allotment option, up to 16,666,667 Private Placement Warrants for an aggregate purchase price of approximately $25,000,000 if the Underwriters’ over-allotment option is exercised in full);

WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $35,000,000, or $40,250,000 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 completion of an initial business combination (as described in the Prospectus, a “Business Combination”) (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 with the terms of this Agreement in the Trust Account established by the Trustee in the United States at JP Morgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) 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, 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, 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 of 1940, as amended, 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 and 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 Representatives 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;

(g) Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so;

(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;

2

(1) 24 months after the closing of the Offering and (2) such later date as may be approved by the Company’s shareholders in accordance with the Company’s Charter, if a Termination Letter has not been received by the Trustee prior to such date, in which case 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, if any, not previously released to the Company pursuant to pay its taxes (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses, if applicable), shall be distributed to the Public Shareholders of record as of such date; provided further, that the Trustee has no obligation to monitor or question the Company’s position that an allocation has been made for taxes payable;

(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, if any, earned on the Property requested by the Company to cover any tax obligation owed by 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 so long as there is no reduction in the principal amount initially deposited in the Trust Account; 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 (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The Company may only withdraw funds from the Trust Account to cover any tax obligation owed by the Company if such funds are held in an interest-bearing account. 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;

(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 to the remitting brokers on behalf of Public Shareholders redeeming Class A ordinary shares the amount required to pay redeemed Class A ordinary shares from Public Shareholders; and

(l) Not make any withdrawals or distributions from the Trust Account other than pursuant to Sections 1(i), (j), or (k) above.

2. Agreements and Covenants of the Company. The Company hereby agrees and covenants to:

In addition, except with respect to its duties under Sections 1(i), (j), and (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;

3

(b) Subject to the provisions of Section 4 of this Agreement, 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 claim, potential claim, 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 consent shall not be unreasonably withheld. The Company may participate in such action with its own counsel;

(c) Pay the Trustee an initial acceptance fee, an annual fee and a transaction processing fee for each disbursement made as set forth on Schedule A hereto, 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 the disbursements are made to the Company pursuant to Section 1(i) solely in connection with the completion of a Business Combination. The Company shall pay the Trustee the initial acceptance fee and first year’s fee at the consummation of the Offering and thereafter on the anniversary of the Effective Date. 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;

(d) In connection with any vote of the Company’s shareholders regarding a Business Combination, provide to the Trustee an affidavit or certificate of a firm regularly engaged in the business of soliciting proxies and/or tabulating shareholder votes (which firm may be the Trustee) verifying the vote of the Company’s shareholders regarding such Business Combination;

(e) In connection with the Trustee acting as Paying/Disbursing Agent pursuant to Exhibit B, the Company will not give the Trustee disbursement instructions which would be prohibited under this Agreement;

(f) Within five business days after the Representatives, on behalf of the Underwriters, exercise the over-allotment option (or any unexercised portion thereof) or such over-allotment option expires, provide the Trustee with a notice in writing (with a copy to the Representatives) of the total amount of the Deferred Discount;

(g) In the event the Company is entitled to receive a tax refund on its tax obligation, and promptly after the amount of such refund is determined on a final basis, provide the Trustee with notice in writing (with a copy to the Representatives) of the amount of such tax refund; and

(h) If the Company seeks to amend any provisions of its Charter that would affect the substance or timing of the Company’s Public Shareholders’ ability to convert or sell their shares to the Company in connection with a Business Combination or with respect to any other provisions relating to the rights of holders of the Class A ordinary shares, (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 conversion option in connection with such Amendment.

3. Limitations of Liability. The Trustee shall have no responsibility or liability to:

(a) 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 party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct;

(b) 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 written 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;

(f) 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), 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;

(g) Verify the correctness of the information set forth in the Registration Statement or to confirm or assure that any acquisition made by the Company or any other action taken by it is as contemplated by the Registration Statement;

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 Sections 2(b) or (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 during which time the Trustee shall 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 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 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).

In executing funds transfers, the Trustee will rely upon all information supplied to it by the Company, including account names, account

6

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.

(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. This Agreement may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and together shall constitute but one instrument.

(c) This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for Sections 1(i), (j), (k), and (l) hereof (which sections may not be modified, amended or deleted without the affirmative vote of sixty-five percent (65%) or more of the then issued and outstanding Class A ordinary shares and Class B ordinary shares, par value $0.0001 per share, of the Company voting together as a single class; provided that no such amendment will affect any Public Shareholder who has properly elected to redeem his Class A ordinary shares in connection with a shareholder vote to amend this Agreement that would affect the substance or timing of the Company’s obligation to redeem 100% of its Class A ordinary shares if the Company does not complete its initial Business Combination within the time frame specified in the Company’s Charter or with respect to any other provisions relating to the rights of holders of the Class A ordinary shares), 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.
