Accordingly, in consideration of the mutual agreements herein contained and

hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Amendments to Credit Agreement. Section 8.02(c) (Conditions to All
Other Extensions of Credit) of the Credit Agreement is hereby amended by
deleting therefrom the following phrase: “, in the case of a Borrowing the sole
purpose of which is to refinance maturing commercial paper,”.

SECTION 2. Representations and Warranties. To induce the other parties hereto to
enter into this Amendment, the Company represents and warrants to each of the
Lenders and each of the Administrative Agents that, after giving effect to this
Amendment, (a) the representations and warranties set forth in the Credit
Agreement are true and correct in all material respects on and as of the
Amendment Effective Date (as defined below) with the same force and effect as
though made on and as of the Amendment Effective Date, except to the extent such
representations and warranties expressly relate to an earlier date; and (b) no
Default has occurred and is continuing.

SECTION 3. Effectiveness. This Amendment shall become effective as of the date
set forth above on the date (the “Amendment Effective Date”) on which the
General Administrative Agent shall have received counterparts of this Amendment
that, when taken together, bear the signatures of the Borrowers and the Required
Lenders.

SECTION 4. Effect of Amendment. Except as expressly set forth herein, this

modify, amend or in any way affect any of the terms, conditions, obligations,
covenants or agreements contained in the Credit Agreement or any other Loan
Document, all of which are ratified and affirmed in all respects and shall

Credit Party to a consent to, or a waiver, amendment, modification or other

contained in the Credit Agreement or any other Loan Document in similar or
different circumstances. This Amendment shall apply and be effective only with

taken together shall constitute but one contract, and shall become effective as
provided in Section 3 of this Amendment. Delivery of an executed counterpart of
