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 June 15, 1991, as supplemented by a Second Supplemental Indenture, dated as of November 1, 2010, and a Fourth Supplemental Indenture, dated as of [—], 2011 (as so supplemented, herein called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A. and as successor to The Bank of New York ), as successor 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, which series is initially limited in aggregate principal amount to $600,000,000; provided that the Company may from time to time or at any time, without the consent of Holders of the Securities of this series, issue additional Notes. Such additional Notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes.

At any time prior to the date that is six months prior to the maturity date of the Securities, the Securities will be redeemable in whole at any time or in part from time to time, at the Company’s option, at a redemption price equal to the greater of (i) 100% of the principal amount of the Securities, or (ii) as determined by the Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest on the Securities (not including any portion of those payments of interest accrued as of 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 (as defined below) plus 30 basis points plus, in each case, accrued and unpaid interest on the Securities to, but not including, the redemption date.

At any time on or after the date that is six months prior to the maturity date of the Securities, the Securities will be redeemable at any time or from time to time, in whole or in part, at the Company’s option, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest on the Securities, calculated assuming a 360-day year consisting of twelve 30-day months, to, but not including, the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of a 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 Securities.

“Comparable Treasury Price” means, with respect to any redemption date, (i) the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotation, or (ii) if the Trustee obtains fewer than three Reference Treasury Dealer Quotations, the average of the quotations.

A-5

“Reference Treasury Dealer” means (i) Merrill Lynch, Pierce, Fenner & Smith Incorporated (successor to Banc of America Securities LLC) and its successors and a Primary Treasury Dealer (defined herein) selected by Wells Fargo Securities, LLC and its successors; however, if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary Treasury Dealer; and (ii) any two other Primary Treasury Dealers selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, 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 the Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the redemption date.

“Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

“Treasury Rate” means, with respect to any redemption date, the annual rate equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

In the case of a partial redemption, selection of the Securities for redemption will be made pro rata, by lot or such other method as the Trustee in its sole discretion deems appropriate and fair; however, any redemption relating to a public equity offering of equity securities will be made on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the Depositary’s procedures). No Securities of a principal amount of $1,000 or less will be redeemed in part. Notice of any redemption will be mailed by first class mail at least 30 days but not more than 60 days before the redemption date to each holder of the Securities to be redeemed at its registered address. If any Securities are to be redeemed in part only, the notice of redemption that relates to the Securities will state the portion of the Securities to be redeemed. New Securities in principal amounts of $1,000 equal to the unredeemed portion of the Securities will be issued in the name of the holder of the Securities upon surrender for cancellation of the original Securities. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Securities or the portions of the Securities called for redemption.

Upon the occurrence of a Change of Control Repurchase Event (as defined in the Indenture), each Holder of the Securities will have the right to require the Company to redeem the Securities on the terms and conditions set forth in the Indenture.

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 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 hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon 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.

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 and of like tenor 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.
