         Re:   Initial Public Offering
               -----------------------

Gentlemen:

         The undersigned officer of Aldabra Acquisition Corporation ("Company"),
in consideration of Morgan Joseph & Co. Inc. ("Morgan Joseph") entering into a
letter of intent ("Letter of Intent") 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 9 hereof):

         1. In the event that the Company fails to consummate a Business
Combination within 18 months from the effective date ("Effective Date") of the
registration statement relating to the IPO (or 24 months under the circumstances
described in the prospectus relating to the IPO), the undersigned will 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 ("Claim") in or to any distribution of the Trust
Fund (as defined in the Letter of Intent) and 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.

         2. 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 of the Company, subject to any
pre-existing fiduciary obligations the undersigned might have.

         3. 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 Morgan Joseph that
the business combination is fair to the Company's stockholders from a financial
perspective.

         4. Neither the undersigned, any member of the family of the
undersigned, nor any Affiliate of the undersigned will be entitled to receive
and will not accept any compensation for services rendered to the Company prior
to 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 an allocable share of Related Party's overhead, $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.

         5. Neither the undersigned, any member of the family of the
undersigned, or any Affiliate of the undersigned will be entitled to receive or
accept a finder's fee or any other compensation in the event the undersigned,
any member of the family of the undersigned or any Affiliate of the undersigned
originates a Business Combination.

         6. The undersigned's biographical information furnished to the Company
and Morgan Joseph and attached hereto as Exhibit A is true and accurate in all
respects, does not omit any material information with respect to the
undersigned's background and contains all of the information required to be
disclosed pursuant to Section 401 of Regulation S-K, promulgated under the
Securities Act of 1933. The undersigned's Questionnaire furnished to the Company

respects. The undersigned represents and warrants that:

     (a) he is not subject to or a respondent in any legal action for, any
injunction, cease-and-desist order or order or stipulation to desist or refrain
from any act or practice

consumer credit reporting agency to release to Morgan Joseph and its legal
representatives or agents (including any investigative search firm retained by
Morgan Joseph) any information they may have about the undersigned's background
