interest granted and provided for by the Loan Agreement as amended hereby, for
the benefit and security of (a) all obligations and indebtedness

agrees that, notwithstanding the execution and delivery hereof, (i) all
rights and remedies of the Lender under the Loan Agreement, (ii) all

lien and security interest granted and provided for thereby are and as amended
hereby shall remain in full force and effect for the benefit and security of

limitation, the indebtedness evidenced by the Revolving Note, the Term Note,
the Equipment Note, the Equipment Note No. 2 and all other Indebtedness (including,
without limitation, the repayment of all sums when due under the Subsidiary Guaranty),
it being specifically understood and agreed that this Amendment shall
constitute and be an acknowledgment and continuation of the rights, remedies,
lien and security interest in favor of the Lender, and the obligations and
indebtedness of the Borrower to the Lender, which exist under the Loan
Agreement as amended hereby, each and all of which are and shall remain applicable
to the Collateral.  This Amendment confirms and assures a lien and continuing first
priority security interest in the Collateral heretofore granted in favor of the
Lender under the Loan Agreement, and nothing contained herein shall in any
manner impair the priority of such lien and security interest.  10.          In
order to induce Lender to enter into this Amendment, the Borrower hereby
represents and warrants to the Lender that as of the date hereto, each of the
representations and warranties set forth in the Loan Agreement, as amended
hereby, are true and correct and the Borrower is in full compliance with all of

agrees to reimburse the Lender for its reasonable legal fees incurred in
documenting the aforesaid loan extension hereinabove described.  [signature page follows]  7
