            fees for each Letter of Credit for the period from and excluding the
            date of issuance of same to and including the date of expiration or
            termination, equal to the average daily face amount of each
            outstanding Letter of Credit multiplied by (i) one and one-half
            percent (1.50%) per annum with respect to Trade Letters


                                       2
<PAGE>
            of Credit or (ii) three and one-half percent (3.50%) with respect to
            Standby Letters of Credit, such fees to be calculated on the basis
            of a 360-day year for the actual number of days elapsed and to be
            payable monthly in arrears on the first day of each month and on the
            last day of the Term (y) to Agent, for the benefit of the Issuer,
            one-quarter percent (.25%) of the face amount of each Standby
            Letters of Credit, and (z) to the Issuer, any and all fees and
            expenses as agreed upon by the Issuer and the Borrowing Agent in
            connection with any Letter of Credit, including, without limitation,
            in connection with the opening, amendment or renewal of any such
            Letter of Credit and any acceptances created thereunder and shall
            reimburse Agent for any and all fees and expenses, if any, paid by
            Agent to the Issuer (all of the foregoing fees, the "Letter of
            Credit Fees"). All such charges shall be deemed earned in full on
            the date when the same are due and payable hereunder and shall not
            be subject to rebate or proration upon the termination of this
            Agreement for any reason. Any such charge in effect at the time of a
            particular transaction shall be the charge for that transaction,
            notwithstanding any subsequent change in the Issuer's prevailing
            charges for that type of transaction. All Letter of Credit Fees
            payable hereunder shall be deemed earned in full on the date when
            the same are due and payable hereunder and shall not be subject to
            rebate or proration upon the termination of this Agreement for any
            reason.

            At the Agent's request at any time while an Event of Default is
            continuing, Borrowers will cause cash to be deposited and maintained
            in an account with Agent, as cash collateral, in an amount equal to
            one hundred and five percent (105%) of the outstanding Letters of
            Credit, and each Borrower hereby irrevocably authorizes Agent, in
            its discretion, on such Borrower's behalf and in such Borrower's
            name, to open such an account and to make and maintain deposits
            therein, or in an account opened by such Borrower, in the amounts
            required to be made by such Borrower, out of the proceeds of
            Receivables or other Collateral or out of any other funds of such
            Borrower coming into any Lender's possession at any time. Agent will
            invest such cash collateral (less applicable reserves) in such
            short-term money-market items as to which Agent and such Borrower
            mutually agree and the net return on such investments shall be
            credited to such account and constitute additional cash collateral.
            No Borrower may withdraw amounts credited to any such account except
            upon cure or waiver of such Event of Default as long as no other
            Event of Default is then continuing or upon payment and performance
            in full of all Obligations and termination of this Agreement or if
            the amounts held therein exceed the amounts available to be drawn
            under such Letters of Credit plus amounts drawn and outstanding
            thereunder by more than 105%.

            (b) Facility Fee. If' for any fiscal quarter during the Term, the
            average daily unpaid balance of the Revolving Advances for each day
            of such fiscal quarter does not equal the Maximum Revolving Advance
            Amount, then Borrowers shall pay to Agent for the ratable benefit of
            Lenders a fee at a rate equal to 3/8 of one percent (.375%) per
            annum on the amount by which the Maximum Revolving Advance Amount
            exceeds such average daily unpaid balance. Such fee shall be payable
            to Agent in arrears on the last day of each fiscal quarter.

            E. Subsection 6.5 is hereby deleted and a new Subsection 6.5 is
substituted therefor to read as follows:

             6.5 Net Worth. Maintain a Net Worth in amounts not less than:
