         applied as set forth in Section 2.6(d), the sale or other disposition
         of other assets resulting in Net Proceeds during any fiscal year not
         exceeding $20,000,000 (or solely in the fiscal year ending December 31,
         2000, such greater amount, not to exceed $23,000,000, to the extent

                  SECTION 4. Effectiveness. This Amendment shall become
effective on the date (the "Effective Date") on or prior to October 31, 2000, if
the Administrative Agent shall have received by fax or otherwise counterparts of
this Amendment signed by the Domestic Borrower and the Required Lenders.

                  In the event the foregoing condition precedent is not
satisfied on or before October 31, 2000, the provisions of this Amendment shall

                  SECTION 5. Continuing Effectiveness. The Credit Agreement
shall remain in full force and effect in accordance with its terms except as
expressly modified by this Amendment. The Domestic Borrower agrees that this
Amendment in no way acts as a release or relinquishment of the liens or other
rights created under the Credit Agreement or any Transaction Document. Such
liens and other rights are hereby ratified and confirmed by the Domestic
Borrower in all respects.

                  SECTION 6. Governing Law. This Amendment shall be governed by
and construed in accordance with the laws of the State of New York.

                  SECTION 7. Counterparts. This Amendment may be signed in any
