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 Partnership, any member of the family of the
undersigned, nor any Affiliate of the Partnership will be entitled to receive
and will not accept any compensation for services rendered to the Company prior

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 Partnership, any member of the family of the
undersigned, or any Affiliate of the Partnership 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 Partnership will escrow its 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 Partnership's Questionnaire furnished to the Company and annexed
