     the terms of the Existing Loan Documents remain unchanged and in full force
     and effect. Bank's agreement to modifications to the existing Obligations
     pursuant to this Loan Modification Agreement in no way shall obligate Bank
     to make any future modifications to the Obligations. Nothing in this Loan
     Modification Agreement shall constitute a satisfaction of the Obligations.
     It is the intention of Bank and Borrower to retain as liable parties all
     makers of Existing Loan Documents, unless the party is expressly released
     by Bank in writing. No maker will be released by virtue of this Loan
     Modification Agreement.
