voluntary prepayments of the Term Loans or permanent reductions of the Revolving

and reduction being in amounts that reflect equal percentages of the Revolving
Credit Commitment in effect and the Term Loans outstanding as of the date of any
such prepayment and reduction; provided that nothing herein shall be deemed to

            (b) From and after the Fifth Amendment Effective Date, the Borrowers
shall not permit the aggregate amount on deposit in all accounts and lockboxes
maintained by the Borrowers and their domestic Subsidiaries, other than the
accounts described in paragraph (a) this Section, any other account maintained
with the Administrative Agent and any payroll account, to be greater than
$500,000 at any time.

            4.4 Cash Flow Forecasts. From and after the Fifth Amendment

known or unknown, which occurred, existed, was taken, permitted or begun prior
to the Fifth Amendment Effective Date, in each case, relating to the Credit
Agreement or any other Loan Document, including without limitation any approval
or acceptance given or denied.

effect to this Fifth Amendment, the Borrowers hereby represent and warrant that
all representations and warranties contained in the Credit Agreement are true
