This Security is one of the series designated on the face hereof, limited in aggregate amount to $500,000,000.

Except as set forth below, the Company shall not be entitled to redeem the Securities.

The Securities shall be redeemable, at any time in whole or from time to time in part, at the Company’s option, at a Redemption Price at any time equal to the greater of:

(i) 100% of the principal amount of the Security to be redeemed; and

(ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Security to be redeemed from the Redemption Date to the Stated Maturity of the Security to be redeemed (exclusive of any interest accrued to the Redemption Date), discounted 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 50 basis points.

plus, in each case, any interest accrued but not paid on the Security to be redeemed to the Redemption Date. Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered holders as of the close of business on the relevant Regular Record Date.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided 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 Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain 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 hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Each of the defeasance and covenant defeasance provisions of Article Thirteen of the Indenture shall apply to this Security.

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 any premium and interest on this Security 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 any premium 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 and of like tenor, 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 $2,000 and integral multiples of $1,000 in excess 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.

This Security shall for all purposes be governed by and construed in accordance with the laws of the State of New York.

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