         NOW, THEREFORE, the parties hereby agree as follows:

         SECTION 1. AMENDMENTS.

         1.1. AMENDMENT TO MATURITY DATE. Section 1.1 of the Credit Agreement is
hereby amended to delete the definition of "MATURITY DATE" therefrom and to
insert in place thereof the following:

                  "MATURITY DATE" shall mean August 10, 2004, unless extended in
         accordance with Section 4.4, or such earlier date on which the Total
         Commitment is terminated.

         1.2. AMENDMENT TO DATE OF PROJECTIONS. Section 8.1 of the Credit
Agreement is hereby amended to delete subsections (c) and (e) therefrom and to
insert in place thereof the following:

                  (c) OFFICER'S COMPLIANCE CERTIFICATES. (i) At the time of the
         delivery of the financial statements provided for in sections 8.1(a)
         and (b), a certificate on behalf of the Borrower of the Chief Financial
         Officer or other Authorized Officer of the Borrower to the effect that,
         to the best knowledge of the Borrower, no Default or Event of Default
         exists or, if any Default or Event of Default does exist, specifying
         the nature and extent thereof and the actions the Borrower proposes to
         take with respect thereto, which certificate shall set forth the

         Event of Default exists or, if any Default or Event of Default does
         exist, specifying the nature and extent thereof and the actions the
         Borrower proposes to take with respect thereto, which certificate shall
         set forth the calculations required to establish compliance with the
         provisions of section 9.8 of this Agreement; and (iii) if after the
         Borrower delivers a certificate pursuant to this section 8.1(c) for any
         fiscal period, the Borrower completes an Acquisition, the Borrower may
         deliver another certificate pursuant to this section 8.1(c) for the
         same fiscal period which gives pro forma effect to such Acquisition for
         the period prior to the date of the Acquisition which is covered by
         such fiscal period or prior periods, in the manner contemplated by the
         definition of Consolidated EBITDA and other applicable defined terms,
         in the computations establishing compliance with such sections.

                  (e) BUDGETS AND FORECASTS. On or before March 31st of any
         fiscal year of the Borrower and its Subsidiaries, a consolidated budget
         in reasonable detail for each of the four fiscal quarters of such
         fiscal year, and (if and to the extent prepared by management of the
         Borrower) for any subsequent fiscal year, as customarily prepared by
         management for its internal use, setting forth, with appropriate
         discussion, the forecasted balance sheet, income statement, operating
         cash flows and capital expenditures of the Borrower and its
         Subsidiaries for the period covered thereby, and the principal
         assumptions upon which such forecast and budget are based.

Agreement is hereby amended to add the following new sentence thereto:

         Notwithstanding the foregoing, commencing January 1, 2002, for the time
         period from January 1 through March 30 of each fiscal year of the
         Borrower, the Borrower will not suffer or permit at any time during any
         such calendar month the ratio of (a) the amount of its Consolidated
         Total Debt for such calendar month to (b) its Consolidated EBITDA for
         the most recently completed 12 calendar months, to exceed 4.00 to 1.00.

         1.4. AMENDMENT TO CAPITAL EXPENDITURE LIMITATION. The Credit Agreement
is hereby amended to delete Section 9.11 therefrom and to insert in place
thereof the following:

                  9.11. CONSOLIDATED CAPITAL EXPENDITURES. The Borrower will
         not, and will not permit any of its Subsidiaries to, make or incur
         Consolidated Capital Expenditures during any fiscal period of the
