This Debenture is one of a duly authorized series of an issue of unsecured debt securities of the Company designated as its 5.20% Debentures, Series 2023 A (the “Debentures”), issued and to be issued under an Indenture dated as of December 1, 1990, between the Company and The Bank of New York Mellon (formerly known as The Bank of New York (successor to JPMorgan Chase Bank, N.A. (formerly known as JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank (successor to The Chase Manhattan Bank (National Association)))))), as Trustee (hereinafter called the “Trustee”, which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture, dated as of March 6, 1996, and the Second Supplemental Indenture, dated as of June 23, 2005 (the Indenture, as so amended and supplemented is hereinafter called the “Indenture”). The Debentures shall be issued in an initial aggregate principal amount of $500,000,000. The Company may at any time, without the consent of the holders of the Debentures, issue additional Debentures that will be part of the same series of debt securities as, rank equally and ratably with, and have the same interest rate, maturity and other terms (except for the issue date, the issue price and, if applicable, the initial interest accrual date and the first interest payment date) as, the Debentures initially issued. Reference is made to the Indenture and any supplemental indenture thereto for the provisions relating, among other things, to the respective rights of the Company, the Trustee and the holders of the Debentures, and the terms on which the Debentures are, and are to be, authenticated and delivered.

Prior to December 1, 2032, which is referred to as the “Par Call Date”, the Company may redeem the Debentures at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Debentures matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, less (b) interest accrued to the date of redemption; and (2) 100% of the principal amount of the Debentures to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but not including, the redemption date.

On or after the Par Call Date, the Company may redeem the Debentures, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Debentures being redeemed plus accrued and unpaid interest thereon to, but not including, the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted each business day by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

2

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semiannual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked price for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semiannual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked price (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Company will notify the Trustee of the redemption price promptly after the calculation thereof, and the Trustee may rely upon the redemption price contained in any such notice and the Trustee shall not be responsible for, or be liable in connection with, the calculation of such redemption price (or any component thereof) or for determining whether manifest error has occurred.

The Company will mail notice of any redemption at least 30 days but not more than 60 days before the redemption date to each registered holder of Debentures to be redeemed.

Unless the Company defaults in payment of the redemption price, on or after the redemption date interest will cease to accrue on the Debentures or portions thereof called for redemption.

If an Event of Default (as defined in the Indenture) shall have occurred and be continuing with respect to the Debentures, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with such effect and subject to the conditions provided in the Indenture. Any such declaration may be rescinded by holders of a majority in principal amount of the outstanding Debentures if all Events of Default with respect to the Debentures (other than the non-payment of principal of the Debentures which shall have become due by such declaration) shall have been remedied.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Debentures at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to the Indenture or to any supplemental indenture with respect to the Debentures, or modifying in any manner the rights of the holders of the Debentures; provided, however, that no such supplemental indenture shall (i) extend the maturity of any Debenture, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or make the principal thereof, or interest thereon, payable in any coin or currency other than that provided in the Debentures without the consent of the holder of each Debenture so affected, or (ii) reduce the aforesaid principal amount of Debentures, the holders of which are required to consent to any such supplemental indenture without the consent of the holders of all Debentures then outstanding.

The Debentures are issuable as registered Debentures only, in the denomination of $2,000 and any integral multiples of $1,000 approved by the Company, such approval to be evidenced by the execution thereof.

3

This Debenture is transferable by the registered holder hereof in person or by his attorney duly authorized in writing on the books of the Company at the office or agency to be maintained by the Company for that purpose, but only in the manner, subject to the limitations and upon payment of any tax or governmental charge for which the Company may require reimbursement as provided in the Indenture, and upon surrender and cancellation of this Debenture. Upon any registration of transfer, a new registered Debenture or Debentures, of authorized denomination or denominations, and in the same aggregate principal amount, will be issued to the transferee in exchange therefor.

The Company, the Trustee, any paying agent and any Security registrar may deem and treat the registered holder hereof as the absolute owner of this Debenture (whether or not this Debenture shall be overdue and notwithstanding any notations of ownership or other writing hereon made by anyone other than the Security registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon as herein provided and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Security registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or interest on this Debenture, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator or against any past, present or future stockholder, officer or member of the Board of Trustees, as such, of the Company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

This Debenture shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of the State of New York.

All terms used in this Debenture which are defined in the Indenture and not defined herein shall have the meanings assigned to them in the Indenture.

This Debenture shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose until the certificate of authentication on the face hereof is manually signed by the Trustee.
