         3. The Borrower represents and warrants to the Lender as follows:

            (a) Borrower is a corporation duly organized, and validly existing
and in good standing under the laws of the state in which it was organized and

every other state wherein the conduct of its business or the ownership of its
property requires such qualification;

            (b) Borrower has the power and authority to execute and deliver this
Agreement and perform its obligations hereunder and has taken all necessary and
appropriate corporate action to authorize the execution, delivery and
performance of this Agreement;

            (c) The Financing Agreement, as amended by this Agreement, and each
of the other Financing Documents remains in full force and effect, and each
constitutes the valid and legally binding obligation of Borrower, enforceable in
accordance with its terms;

            (d) All of Borrower's representations and warranties contained in
the Financing Agreement and the other Financing Documents are true and correct
on and as of the date of Borrower's execution of this Agreement; and

            (e) No Event of Default and no event which, with notice, lapse of
time or both would constitute an Event of Default, has occurred and is
continuing under the Financing Agreement or the other Financing Documents which
has not been waived in writing by the Lender.

         4. The Financing Agreement is hereby amended as follows:

(as determined in accordance with GAAP consistently applied, except that the
outstanding principal balance of the Revolving Loan shall not be included in
current liabilities) of not less than 1.75 to 1.0.

            (b) Section 5.1.15 of the Financing Agreement is hereby deleted in 
its entirety and substituted therefor is the following:

            (c) Section 5.1.16 of the Financing Agreement is hereby deleted in
its entirety and substituted therefor is the following:

               Leverage Ratio. The Borrower will at all times maintain, tested

basis), a ratio of Senior Funded Indebtedness to EBITDA of not less than 2.50 to
1.0.

               "Senior Funded Indebtedness" means at any date, the aggregate of
all Indebtedness for Borrowed Money of the Borrower and its Subsidiaries, to the
Lender whether secured or unsecured, having a final maturity (or which by the
terms thereof is renewable or extendible at the option of the obligor for a
period ending) more than a year after that date.

         5. The Borrower hereby issues, ratifies and confirms the
representations, warranties and covenants contained in the Financing Agreement,
as amended hereby. The Borrower agrees that this Agreement is not intended to
and shall not cause a novation with respect to any or all of the Obligations.

         6. The Borrower acknowledges and warrants that the Lender has acted in
good faith and has conducted in a commercially reasonable manner its

in connection with the Financing Agreement and the Obligations, the Borrower
hereby waiving and releasing any claims to the contrary.

         7. The Borrower shall pay at the time this Agreement is executed and

including, but not limited to, reasonable fees and expenses of the Lender's
counsel and all recording fees, taxes and charges.

         8. This Agreement may be executed in any number of duplicate originals
or counterparts, each of such duplicate originals or counterparts shall be
deemed to be an original and all taken together shall constitute but one and the
same instrument. The Borrower agrees that the Lender may rely on a telecopy of
any signature of the Borrower. The Lender agrees that the Borrower may rely on a
telecopy of this Agreement executed by the Lender.




         IN WITNESS WHEREOF, the Borrowers and the Lender have executed this
