Date of Authentication: June 10, 2005

                             J.P. Morgan Trust Company, National Association,
                                  as Trustee

                             By: _________________________________

                               REVERSE OF SECURITY

      This Security is one of a duly authorized issue of securities of the
Company (herein called the "SECURITIES"), issued and to be issued in one or more
series under an Indenture, dated as of February 12, 2001 (herein called the
"INDENTURE"), between the Company and J.P. Morgan Trust Company, National
Association (as successor in interest to Bank One Trust Company, National
Association), as Trustee (herein called the "TRUSTEE," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof, initially limited in aggregate
principal amount to $500,000,000.

      The Notes will be redeemable at the option of the Company, in whole at any
time or in part from time to time (each, a "REDEMPTION DATE") at a redemption
price equal to the greater of (i) 100% of their principal amount plus accrued
interest to the Redemption Date and (ii) the sum, as determined by the
Independent Investment Banker, of the present values of the principal amount and
the remaining scheduled payments of interest on the Notes to be redeemed
(exclusive of interest accrued to such Redemption Date), discounted from the
scheduled payment dates to the Redemption Date on a semi-annual basis (assuming
a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15
basis points plus accrued but unpaid interest thereon to the Redemption Date.
Notwithstanding the foregoing, installments of interest on Notes that are due
and payable on an interest payment date falling on or prior to the relevant
Redemption Date will be payable to the holders of such Notes registered as such
at the close of business on the relevant record date according to their terms
and the provisions of the Indenture.

      "COMPARABLE TREASURY ISSUE" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the Notes to be redeemed.

      "COMPARABLE TREASURY PRICE" means, with respect to any Redemption Date,
the average of the Reference Treasury Dealer Quotations for such Redemption
Date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or if the Trustee obtains fewer than three such Reference Treasury
Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

      "INDEPENDENT INVESTMENT BANKER" means one of the Reference Treasury
Dealers appointed by the Trustee after consultation with the Company.

<PAGE>

      "REFERENCE TREASURY DEALER" means (a) each of Merrill Lynch, Pierce,
Fenner & Smith Incorporated and Citigroup Global Markets Inc. and their
respective successors, unless either of them ceases to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), in
which case the Company shall substitute another Primary Treasury Dealer; and (b)
any other Primary Treasury Dealer selected by the Company.

      "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to each
Reference Treasury Dealer and any Redemption Date for the Notes, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.
New York City time, on the third Business Day preceding such Redemption Date.

      "TREASURY RATE" means, with respect to any Redemption Date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, calculated on the third Business Day preceding such Redemption
Date using a price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) equal to the Comparable Treasury price for such
Redemption Date.

      This Security will be subject to defeasance and discharge and to
defeasance of certain obligations as set forth in the Indenture.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

      As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default

<PAGE>

as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall
not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

      No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security herein provided, and at the times, place and rate, and
in the coin or currency, herein prescribed.

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of (and
premium, if any) and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

      The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same.

      No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

      Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

      All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.
