         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

undersigned's Insider Shares ("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

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 EBC 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, TerraNova Management Corp. ("Related Party"), shall be allowed
to charge the Company an allocable share of Related Party's overhead, up to
$7,500 per month, to compensate it for the Company's use of Related Party's
offices, utilities and personnel. 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.

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 EBC 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
