          Re: Initial Public Offering

Gentlemen:

          The undersigned officer and director of Aldabra 2 Acquisition Corp. (“Company”), in consideration of Lazard Capital Markets LLC (“Lazard”) agreeing to underwrite an initial public offering of the securities of the Company (“IPO”) and embarking on the IPO process, hereby agrees as follows (certain capitalized terms used herein are defined in paragraph 15 hereof):

          1. If the Company solicits approval of its stockholders of a Business Combination, the undersigned will vote all Insider Shares beneficially owned by him in accordance with the majority of the votes cast by the holders of the IPO Shares.

          2. In the event that the Company fails to consummate a Business Combination within 24 months from the effective date (“Effective Date”) of the registration statement relating to the IPO, the undersigned will (i) cause the Trust Fund to be liquidated and distributed to the holders of IPO Shares and (ii) take all reasonable actions within his power to cause the Company to liquidate as soon as reasonably practicable. The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Fund and any remaining net assets of the Company as a result of such liquidation with respect to the Insider Shares beneficially owned by him (“Claim”) and hereby waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company and

will not seek recourse against the Trust Fund for any reason whatsoever. In the event of the liquidation of the Trust Fund, the undersigned agrees to indemnify and hold harmless the Company against any and all loss, liability, claims, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) which the Company may become subject as a result of any claim by any vendor, service provider, financing provider or other person who is owed money by the Company for services rendered or products sold or contracted for, or by any target business, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Fund and only if such a vendor or prospective target business does not execute an agreement waiving any claims against the Trust Fund. Additionally, in the case of a prospective target business that did not execute a waiver, such liability will only be in an amount necessary to ensure that public stockholders receive no less than $10.00 per share upon liquidation.

          3. In order to minimize potential conflicts of interest which may arise from multiple affiliations, the undersigned agrees to present to the Company for its consideration, prior to presentation to any other person or entity, any suitable opportunity to acquire an operating business, until the earlier of the consummation by the Company of a Business Combination, the liquidation of the Company or until such time as the undersigned ceases to be an officer or director of the Company, subject to any pre-existing fiduciary and contractual obligations the undersigned might have.

          4. The undersigned acknowledges and agrees that the Company will not consummate any Business Combination which involves a company which is affiliated with any of the Insiders unless the Company obtains an opinion from an independent investment banking firm reasonably acceptable to Lazard that the business combination is fair to the Company’s stockholders from a financial perspective.

          5. Neither the undersigned, any member of the family of the undersigned, nor any affiliate (“Affiliate”) of the undersigned will be entitled to receive and will not accept any compensation for services rendered to the Company prior to or in connection with the consummation of the Business Combination; provided that commencing on the Effective Date, Terrapin Partners LLC (“Related Party”), shall be allowed to charge the Company $7,500 per month, to compensate it for certain administrative, technology and secretarial services, as well as the use of certain limited office space, including a conference room in New York City, that it will provide to the Company. Related Party and the undersigned shall also be entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination.
