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 January 15, 1998 (such instrument as originally executed and delivered and as supplemented or amended from time to time, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., successor to JPMorgan Chase Bank, N.A. (formerly known as The Chase Manhattan Bank), as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a description 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. 
    The Company may redeem all or any portion of the Securities of this series, at its option, at any time or from time to time, (A) prior to May 15, 2029, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Securities of this series being redeemed on the Redemption Date or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series being redeemed on that Redemption Date that would be due if the Securities of this series matured on May 15, 2029 (not including the portion of any payments of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate plus 15 basis points, as determined by a Reference Treasury Dealer appointed by the Company for such purpose; and (B) on or after May 15, 2029, at a Redemption Price equal to 100% of the principal amount of the Securities of this series being redeemed on the Redemption Date; plus, in each case, accrued and unpaid interest thereon to the 








Redemption Date.  Notwithstanding the foregoing, installments of interest on Securities of this series 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 Holders as of the close of business on the relevant record date in accordance with the terms of the Securities of this series and the Indenture.  The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.


If notice has been given as provided in the Indenture and funds for the redemption of any Securities of this series (or any portion thereof) called for redemption shall have been made available on the Redemption Date referred to in such notice, such Securities (or any portion thereof) will cease to bear interest on the date fixed for such redemption specified in such notice and the only right of the Holders of such Securities will be to receive payment of the Redemption Price.
Notice of any optional redemption of Securities of this series (or any portion thereof) will be given to Holders at their addresses, as shown in the Security Register for such Securities, not more than 60 nor less than 10 days prior to the date fixed for redemption. The notice of redemption will specify, among other items, (i) the Redemption Price or the manner of calculation of the Redemption Price and (ii) the principal amount of the Securities of this series held by such Holder to be redeemed if less than all of such Securities.  If less than all of the Securities of this series are to be redeemed at the option of the Company, the Securities to be redeemed will be selected in accordance with the procedures of the Depositary.  
As used herein:
“Adjusted Treasury Rate” means, with respect to any applicable Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming 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.
    “Comparable Treasury Issue” means the U.S. Treasury security selected by a Reference Treasury Dealer appointed by the Company for such purpose as having a maturity comparable to the remaining term of this Security to be redeemed (assuming for this purpose that such Security matured on May 15, 2029) 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 such Security (assuming for this purpose that such Security matured on May 15, 2029).


    “Comparable Treasury Price” means, with respect to any applicable Redemption Date, (A) if the Company obtains three or more Reference Treasury Dealer Quotations, the average of such Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, (B) if the Company obtains two such Reference Treasury Dealer Quotations, the average of such quotations, or (C) if only one Reference Treasury Dealer Quotation is received, such quotation.


“Primary Treasury Dealer” means a primary U.S. government securities dealer in the United States.
    “Reference Treasury Dealer” means each of (A) BNP Paribas Securities Corp., J.P. Morgan Securities LLC, a Primary Treasury Dealer selected by MUFG Securities Americas Inc. and a Primary Treasury Dealer selected by U.S. Bancorp Investments, Inc.; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor 








another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company.


“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any applicable Redemption Date, the average 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 Company by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such Redemption Date.


The Securities of this series will not be subject to any sinking fund.
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.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the affected Securities at the time Outstanding, on behalf of the Holders of all such Securities, 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 under the Indenture, 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 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.
