Gentlemen:

         The undersigned stockholder and director 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 10 hereof):

         1. If the Company solicits approval of its stockholders of a Business
Combination, the undersigned will vote all Insider Shares 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 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 in or to any distribution of the Trust Fund (as
defined in the Letter of Intent) as a result of such liquidation with respect to
the undersigned's Insider Shares ("Claim") and

or arising out of, any contracts or agreements with the Company and will not
seek recourse against the Trust Fund for any reason whatsoever.

         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 the undersigned
shall 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 will escrow his Insider Shares for the three year
period commencing on the Effective Date subject to the terms of a Stock Escrow
Agreement which the Company will enter into with the undersigned and an escrow
agent acceptable to the Company.

         7. The undersigned agrees to be a member of the Board of Directors of
the Company until the earlier of the consummation by the Company of a Business
Combination or the liquidation of the Company. 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

         9. The undersigned authorizes any employer, financial institution, or
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

in requesting and obtaining the Information and the undersigned hereby releases
them from liability for any damage whatsoever in that connection.
