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”) entered into by and between Atlantic Alliance Partnership Corp., a business company incorporated under the laws of the British Virgin Islands with limited liability (the “Company”), and Citigroup Global Markets Inc., (the “Underwriter”), relating to an underwritten initial public offering (the “Public Offering”), of 7,500,000 of the Company’s ordinary shares, no par value (the “Ordinary Shares”). The Ordinary Shares shall be sold in the Public Offering pursuant to the registration statement on Form S-1 No. 333- 202235 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”) and the Company shall apply to have the Ordinary Shares listed on the NASDAQ Capital Market. Certain capitalized terms used herein are defined in paragraph 10 hereof.

In order to induce the Company and the Underwriters 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, each of the undersigned hereby agrees with the Company as follows:

1. Each of the undersigned agrees that if the Company seeks shareholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, he shall vote all Founder Shares and Placement Shares held by him and any shares acquired by him in the Public Offering or the secondary public market in favor of such proposed Business Combination.

2. Each of the undersigned hereby agrees that in the event that the Company fails to consummate a Business Combination (as described in the Underwriting Agreement) within 18 months from the closing of the Public Offering, or such later period approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, each of the undersigned 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 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, including interest not previously released to the Company to pay its tax obligations (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, commence a voluntary liquidation and thereby a formal dissolution, subject in each case to the Company’s obligations under the laws of the British Virgin Islands, to provide for claims of creditors and requirements of applicable law. Each of the undersigned agrees to not propose any amendment to the Company’s amended and restated memorandum and articles of association that would affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 18 months from the closing of the Public Offering, unless the Company provides its Public Shareholders with the opportunity to redeem their Ordinary 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 its tax obligations, divided by the number of then outstanding public shares.

Each of the undersigned acknowledges that he 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 or Placement Shares. Each of the undersigned hereby further waives, with respect to any Ordinary Shares held by him, any redemption rights he may have in connection with 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 (although each of the undersigned shall be entitled to redemption and liquidation rights with respect to any Ordinary Shares (other than the Founder Shares and Placement Shares) he holds if the Company fails to consummate a Business Combination within 18 months from the date of the closing of the Public Offering).

3. During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, each of the undersigned shall not (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, and the rules and regulations of the Commission promulgated thereunder, with respect to any Ordinary Shares, or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by him, (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 Ordinary Shares, or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by him, 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). 

4. [intentionally omitted]

5. (a) Each of the undersigned hereby agrees not to participate in the formation of, or become an officer or director of, any other blank check company until the Company has entered into a definitive agreement with respect to a Business Combination or the Company has failed to complete a Business Combination within 18 months after the closing of the Public Offering.

(b) Each of the undersigned hereby agrees and acknowledges that: (i) each of the Underwriters and the Company would be irreparably injured in the event of a breach by him of his obligations under paragraph 5(a), (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.

6 (a) Subject to certain limited exceptions, each of the undersigned agrees not to sell, assign, transfer or dispose of the Founder Shares until one year after the completion of an initial Business Combination or earlier if, subsequent to an initial Business Combination, (x) the last sale price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations) for any 20 trading days within any 30 trading day period commencing at least 150 days after an initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, stock exchange or other similar transaction after an initial Business Combination that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property.

(b) Each of the undersigned agrees that he shall not effectuate any Transfer of Placement Shares, until 30 days after the completion of a Business Combination. The restrictions contained in paragraphs 6(a) and 6(b) hereof are collectively the “Lock-up”.

(c) Notwithstanding the provisions set forth in paragraphs 6(a) and (b), in the event of (i) the Company’s liquidation prior to the completion of an initial Business Combination or (ii) the completion of a liquidation, merger, stock exchange 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 Company’s completion of an initial Business Combination, the lockup period shall terminate. Transfers of the Founder Shares and Placement Shares are further permitted as set forth in clauses (i) through (vi) below, provided that any transferees enter into a written agreement agreeing to be bound by the Lock-up. Permitted transfers include: (i) transfers to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any equity holders of AAP Sponsor (PTC) Corp (the “Sponsor”) or their affiliates, or any affiliates of the Sponsor, (ii) transfers by gift to an equity holder of the Sponsor’s immediate family or to a trust, the beneficiary of which is an equity holder of the Sponsor’s immediate family, an affiliate of the Sponsor or to a charitable organization; (iii) transfers by virtue of laws of descent and distribution upon the death of an equity holder of the Sponsor or an officer or director; (iv) transfers pursuant to a qualified domestic relations order of an equity holder or an officer or director; (v) transfers by virtue of the laws of the British Virgin Islands or the Sponsor’s memorandum and articles of association or the rights attaching to the equity interests in the Sponsor upon dissolution of the Sponsor; and (vi) transfers by private sales or transfers made in connection with the consummation of an initial Business Combination at prices no greater than the price at which such shares were originally purchased.

Each of the undersigned’s questionnaire furnished to the Company is true and accurate in all respects with respect to such undersigned.
