         "bankruptcy remote subsidiary" in connection with a securitization of
         Receivables, to the extent such securitization is permitted under
         Sections 7.3(A) and 7.3(D)(vii)."

                           (c)      Section 7.3(R) of the Credit Agreement shall
be amended by adding the following proviso to the end of such Section:

         "; provided, however, that Section 7.3(R) shall not apply to a Domestic
         Subsidiary that is organized by the Company to serve as a so-called
         "bankruptcy remote subsidiary" in connection with a securitization of
         Receivables, to the extent such securitization is permitted under
         Sections 7.3(A) and 7.3(D)(vii)."

                  2.       Representations and Warranties of the Borrowers. Each
Borrower represents and warrants that:

                           (a)      Such Borrower has the requisite power and
authority and legal right to execute and deliver this Amendment and to perform
its obligations hereunder. The execution and delivery by such Borrower of this
Amendment and the performance of its obligations hereunder have been duly
authorized by proper proceedings, and this Amendment constitutes a legal, valid
and binding obligation of such Borrower enforceable against such Borrower in
accordance with its terms, except as enforceability may be limited by any
bankruptcy, insolvency or similar law affecting the enforcement of creditors'
rights generally;

                           (b)      Each of the representations and warranties
contained in the Credit Agreement and the other Loan Documents is true and
correct in all material respects on and as of the date hereof as if made on the
date hereof; and

                           (c)      After giving effect to this amendment, no
Default or Unmatured Default has occurred and is continuing.

                  3.       Effective Date. Section 1 of this Amendment shall
become effective upon the execution and delivery hereof by the Borrowers, the
Agents and the Required Lenders (the "Effective Date").

                  4.       Reference to and Effect Upon the Credit Agreement.

                           (a)      Except as specifically amended above, the
Credit Agreement and the other Loan Documents shall remain in full force and
effect and are hereby ratified and confirmed.

                           (b)      The execution, delivery and effectiveness of
this Amendment shall not operate as a waiver or any other right, power or remedy
of any Agent or Lender under the Credit Agreement or any other Loan Document, or
constitute a waiver of any provision of the Credit Agreement or any Loan
Document, except as specifically set forth herein. Upon the effectiveness of
this Amendment, each reference in the Credit Agreement to "this Agreement",
"hereunder", "hereof" or words of similar import shall mean and be a reference
to the Credit

Agreement as amended hereby, and each reference in the other Loan Documents to
the Credit Agreement shall mean and be a reference to the Credit Agreement as
amended hereby.

                  5.       Costs and Expenses. Each Borrower hereby affirms its
obligation under Section 11.6 of the Credit Agreement to reimburse the
Administrative Agent for all reasonable costs and out-of-pocket expenses
(including reasonable attorneys' and paralegals' fees and time charges of
attorneys and paralegals for the Administrative Agent) paid or incurred by the
Administrative Agent in connection with the preparation, negotiation, execution,
delivery, syndication, review, proposed or completed amendment, waiver or
modification, and administration of the Loan Documents.

                  6.       GOVERNING LAW. ANY DISPUTE BETWEEN ANY BORROWER AND
THE ADMINISTRATIVE AGENT, ANY LENDER OR ANY OTHER HOLDER OF OBLIGATIONS ARISING
OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP
ESTABLISHED BETWEEN THEM IN CONNECTION WITH, THIS AMENDMENT OR ANY OF THE OTHER
LOAN DOCUMENTS, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE,
SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (BUT WITHOUT REGARD TO
THE CONFLICTS OF LAWS PROVISIONS) OF THE STATE OF NEW YORK.

                  7.       Headings. Section headings in this Amendment are
included herein for convenience of reference only and shall not constitute a
part of this Amendment for any other purposes.

                  8.       Counterparts. This Amendment may be executed in any
number of counterparts, each of which when so executed shall be deemed an
original but all of such counterparts shall constitute one and the same
instrument.
