Dear Mr. Hunt:

         Reference is hereby made to the above referenced Limited Guaranty and
Pledge Agreement. This letter constitutes the agreement of Bank to hold the
Limited Guaranty and Pledge Agreement as escrow agent and in escrow until such
time as Marshall Hunt interferes with the daily operations of the Borrower in
the reasonable discretion of the Bank. If Marshall Hunt interferes with the
daily operations of the Borrower in the reasonable discretion of the Bank, the
Bank shall provide notice in writing of the breaking of the escrow to the
addressee of this letter, which shall be deemed to have been given (i) 72 hours
after being sent by certified or registered mail, return receipt requested,
postage prepaid and addressed as set forth above; or (ii) if by personal
delivery when personally delivered or (iii) if by facsimile, upon transmission
and receipt. Rejection or other refusal to accept or inability to deliver
because of a changed address of which no notice has been received shall also
constitute service of notice. Once notice has been given, Bank shall have the
right but not the obligation to exercise its remedies pursuant to the Limited
Guaranty and the Pledge Agreement. This letter embodies and confirms the
agreement of the Bank relating to the holding of the Limited Guaranty and Pledge
Agreement in escrow and supercedes all prior agreements, representation and
understandings relating to the subject matter hereof.
