            Compliance Certificate is required to be delivered pursuant to
            Section 7.02(b); provided, however, that if a Compliance Certificate

            AGENT-RELATED PERSONS HAVE ANY LIABILITY TO THE BORROWER, ANY LENDER
            OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, including,
            without limitation, direct or indirect, special, incidental or

            the Lenders a successor L/C Issuer or Swing Line Lender hereunder;
            provided, however, that no failure by the Borrower to appoint any
            such successor shall affect the resignation of Citibank as L/C
            Issuer or CNAI as Swing Line Lender, as the case may be. If Citibank
            resigns as L/C Issuer, it shall retain all the rights and
            obligations of the L/C Issuer hereunder with respect to all Letters
            of Credit outstanding as of the effective date of its resignation as

            Agreement, (ii) any pledgee referred to in Section 11.07(f) or (iii)
            any direct or indirect contractual counterparty or prospective
            counterparty (or such contractual counterparty's or prospective
            counterparty's professional advisor) to any credit derivative
            transaction relating to obligations of the Loan Parties;

            (vvvv) Section 11.16 is hereby amended to read as follows:

                  Under any circumstances set forth in the second paragraph of
            this Section 11.16 or elsewhere in this Agreement providing that the
            Borrower shall have the right to replace a Lender as a party to this
            Agreement, the Borrower may, upon notice to such Lender and the
            Administrative Agent, replace such Lender by causing such Lender to
            assign its Commitment and outstanding Loans (with the assignment fee
            to be paid by the Borrower in such instance) pursuant to Section
            11.07(b) to one or more other Lenders or Eligible Assignees procured
            by the Borrower (each such Lender or Eligible Assignee, a
            "Replacement Lender"); provided, however, that if the Borrower
            elects to exercise such right with respect to any Lender pursuant to
            Section 3.06(b), it shall be obligated to replace all Lenders that
            have made similar requests for compensation pursuant to Section 3.01
            or 3.04. The Borrower shall (x) pay in full all principal, interest,
            fees and other amounts owing to such Lender through the date of
            replacement (including any amounts payable pursuant to Section
            3.05), (y) provide appropriate assurances and indemnitees (which may
            include letters of credit) to the L/C Issuer and the Swing Line
            Lender as each may reasonably require with respect to any continuing
            obligation to fund participation

                                       28
<PAGE>

            interests in any L/C Obligations or any Swing Line Loans then
            outstanding, and (z) release such Lender from its obligations under
            the Loan Documents. Any Lender being replaced shall execute and
            deliver an Assignment and Assumption with respect to such Lender's
            Commitment and outstanding Loans and participations in L/C
            Obligations and Swing Line Loans; provided that, the failure by such
            replaced Lender to execute and deliver an Assignment and Assumption
            shall not impair the validity of the removal of such replaced Lender
            and the mandatory assignment of a replaced Lender's Commitments and
            outstanding Loans and participations in L/C Obligations and Swing
            Line Loans pursuant to this Section 11.16 shall nevertheless be
            effective without the execution by such replaced Lender of an
            Assignment and Assumption.

                  If, in connection with any proposed change, waiver, discharge
            or termination to any of the provisions of this Agreement as
            contemplated by clauses (b) through (g), inclusive, of the first
            proviso in Section 11.01, the consent of the Required Lenders is
            obtained but the consent of one or more of such other Lenders whose
            consent is required is not obtained, then the Borrower shall have
            the right to replace each such non-consenting Lender or Lenders with
            one or more Replacement Lenders pursuant to this Section 11.16 so
            long as at the time of such replacement, each such Replacement
            Lender consents to the proposed change, waiver, discharge or
            termination.

            (wwww) A new Section 11.20 is hereby added and shall read as
      follows:

            11.20 USA PATRIOT Act Notice.
