NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and for other valuable considerations, Borrower, Agents and the Banks agree as follows: 1. Section 5.7 of the Credit Agreement is hereby amended to delete subsection (c) therefrom and to insert in place thereof the following: (c) LEVERAGE RATIO. Borrower shall not suffer or permit at any time the Leverage Ratio to exceed: (i) 5.00 to 1.00 for the period from the Closing Date through December 30, 1999 at any time that the Leverage Ratio Condition exists during such period; (ii) on December 31, 1999 through March 30, 2000, 5.00 to 1.00 or, in the event that the Tranche D Leverage Ratio Condition exists, 4.50 to 1.00; (iii) on March 31, 2000 through June 29, 2000, 5.00 to 1.00; (iv) on June 30, 2000 through September 29, 2000, 5.00 to 1.00 or, in the event that the Tranche D Leverage Ratio Condition exists, 4.75 to 1.00; provided, however, that, if, on June 30, 2000, the Tranche D Leverage Ratio Condition exists and the Leverage Ratio is greater than 4.75 to 1.00 but less than 5.00 to 1.00, then an Event of Default shall not be deemed to have occurred under this Agreement by virtue of the breach of this subpart (iv) of this Section 5.7(c) so long as the ratio for Borrower of (A) Total Funded Indebtedness (outstanding on July 31, 2000) to (B) 2 Consolidated Pro-Forma EBITDA (based upon the financial statements of Borrower for the fiscal quarter ended June 30, 2000 and the three (3) previous fiscal quarters) is less than 4.75 to 1.00 on July 31, 2000; and (v) on September 30, 2000 and thereafter, 5.00 to 1.00 or, in the event that the Tranche D Leverage Ratio Conditions exists, 4.00 to 1.00. 2. The Credit Agreement is hereby amended to delete Section 7.9 therefrom in its entirety and to insert in place thereof the following: SECTION 7.9. DESIGNATED SENIOR INDEBTEDNESS . If any Company shall incur or permit to exist any Designated Senior Indebtedness (as defined in the Indenture) other than the Debt. 3. Borrower, Agents and the Banks agree that, notwithstanding any provision of the Credit Agreement to the contrary, no Subsidiary shall (a) become a Guarantor with respect to any of the Indebtedness incurred in connection with the Senior Subordinated Notes, (b) merge with Borrower, or (c) sell, lease, transfer or otherwise dispose of all or a substantial part of its assets to Borrower. 4. Borrower, Agents and the Banks agree that, notwithstanding any provision of the Credit Agreement to the contrary, if the Tranche D Leverage Ratio Condition exists (or immediately after consummating any Acquisition would exist), no Acquisition otherwise permitted pursuant to Section 5.13 of the Credit Agreement, shall occur during the period from the date of this Amendment through September 30, 2000 (the "Restricted Period") unless the Leverage Ratio, both before and after consummating such Acquisition, is less than or equal to (a) 4.50 to 1.00 for the period from the date of this Amendment through June 29, 2000, and (b) 4.00 to 1.00 thereafter. In the event that, without the prior written consent of Agents and the Banks, an Acquisition shall occur during the Restricted Period in violation of the preceding sentence, such Acquisition shall constitute an Event of Default under the Credit Agreement. 5. Concurrently with the execution of this Amendment, Borrower shall: (a) cause each Guarantor of Payment to consent and agree to and acknowledge the terms of this Amendment; (b) pay an amendment fee to (i) Administrative Agent, for its own account, in the amount of Twenty-Five Thousand Dollars ($25,000) and (ii) Co-Agent, for its own account, in the amount of Ten Thousand Dollars ($10,000); and (c) pay all legal fees and expenses of Administrative Agent in connection with this Amendment. 2 3 5.

Each reference that is made in the Credit Agreement or any other writing to the Credit Agreement shall hereafter be construed as a reference to the Credit Agreement as amended hereby.
