      Re:First Amendment to Note Purchase Agreement dated as of July 22, 2005

                                                  Dated as of September 29, 2005

To the institutional investors (the "Purchasers")
Named in Schedule A to the hereinafter
described Note Purchase Agreement

Ladies and Gentlemen:

      Reference is made to the Note Purchase Agreement dated as of July 22, 2005
(the "Note Purchase Agreement") between the Company and each of you under and
pursuant to which the Company has issued and sold $100,000,000 aggregate
principal amount of 2005 Series C 5.19% Senior Notes due October 1, 2023 (the
"Notes") on the date hereof. Terms used but not otherwise defined herein shall
have the same meaning as ascribed to such terms in the Note Purchase Agreement.

      At the time of execution of the Note Purchase Agreement, the Company and
the Purchasers expected that the Notes would be issued pursuant to a Seventeenth
Supplemental Indenture which is attached as Exhibit A to the Note Purchase
Agreement. Subsequent to the execution and delivery of the Note Purchase
Agreement, the Company issued a series of notes pursuant to a Seventeenth
Supplemental Indenture. Accordingly, the Notes will be issued pursuant to an
Eighteenth Supplemental Indenture. The parties hereto agree that all references
to the "Seventeenth Supplemental Indenture" in the Note Purchase Agreement and
in the Seventeenth Supplemental Indenture attached as Exhibit A to the Note
Purchase Agreement shall be amended to refer to the "Eighteenth Supplemental
Indenture".

      Except as expressly set forth above, the parties agree that the Note
Purchase Agreement is hereby ratified and confirmed in all respects and shall
remain in full force and effect.

      This Amendment shall be binding upon the (i) the Company and its
successors, and (ii) the Purchasers and their successors and assigns, including
each successive holder or holders of any Note.

      This Amendment shall be effective as of the date first written above upon
the execution of this Amendment by the Company and each Purchaser.

      This Amendment may be executed in any number of counterparts, each
executed counterpart constituting an original but all together only one
agreement.

<PAGE>

      This Amendment shall be construed and enforced in accordance with, and the
rights of the parties shall be governed by, the law of the State of New York
excluding choice-of-law principles of the law of such State that would require
the application of the laws of a jurisdiction other than such State.

and year first above written.
