                  2. Alternate Currency Commitment. The reference in the
definitions of "Alternate Currency Commitment" and "Alternate Currency Sublimit"

addition, each Bank's Alternate Currency Commitment shall be as set forth under

definitions of "Dollar Commitment" and "Dollar Sublimit" to "$350,000,000" is
hereby deleted and "$250,000,000" substituted therefore. In addition, each

the signature pages hereof, rather than on the signature pages to the Credit
Agreement.

                  4. Effective Date. This Amendment shall become effective upon
receipt by the Administrative Agent of counterparts hereof signed by the
Borrower and the Banks (the date of such receipt being deemed the "Effective
Date").

                  5. Representations and Warranties. Borrower hereby represents
and warrants that as of the Effective Date, all the representations and
warranties set forth in the Credit Agreement, as amended hereby (other than
representations and warranties that expressly speak as of a different date), are
true and complete in all material respects.

                  6. Entire Agreement. This Amendment constitutes the entire and
final agreement among the parties hereto with respect to the subject matter
hereof and there are no other agreements, understandings, undertakings,
representations or warranties among the parties hereto with respect to the
subject matter hereof except as set forth herein.

construed in accordance with, the law of the State of New York.

                  8. Counterparts. This Amendment may be executed in any number
of counterparts, all of which taken together shall constitute one and the same
agreement, and any of the parties hereto may execute this Amendment by signing
any such counterpart.

                  9. Headings, Etc. Section or other headings contained in this
Amendment are for reference purposes only and shall not in any way affect the
meaning or interpretation of this Amendment.


                  10. No Further Modifications. Except as modified herein, all
of the terms and conditions of the Credit Agreement, as modified hereby shall
remain in full force and effect and, as modified hereby, the Borrower confirms
and ratifies all of the terms, covenants and conditions of the Credit Agreement
in all respects.
