Notwithstanding the foregoing, if the date hereof is after the fifteenth calendar day preceding a February 9 or August 9, as the case may be, and before such February 9 or August 9, this Note shall bear interest from such February 9 or August 9; provided however, that if the Company shall default in the payment of interest due on such February 9 or August 9, then this Note shall bear interest from the next preceding February 9 or August 9 to which interest has been paid, or, if no interest has been paid on the Notes, from February 9, 2022.

TRUSTEE’S CERTIFICATE
OF AUTHENTICATION

This is one of the

Securities of the Series

designated herein issued

under the within-

mentioned Indenture.

THE BANK OF NEW YORK MELLON, as Trustee

   by ______________________________

 Authorized Signatory

This security is one of a duly authorized issue of unsecured debentures, notes or other evidences of indebtedness of the Company (hereinafter called the “Securities”), of the series hereinafter specified, all issued or to be issued under an indenture dated as of October 1, 1993, duly executed and delivered by the Company to The Bank of New York Mellon, a New York banking corporation, as trustee (hereinafter called the “Trustee”), as supplemented by the First Supplemental Indenture dated as of December 15, 1995, between the Company and the Trustee, as trustee (hereinafter called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights and duties thereunder of the Trustee, the Company and the holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest at different rates, may have different conversion prices (if any), may be subject to different redemption provisions, may be subject to different sinking, purchase or analogous funds, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 3.430% Notes due 2052 of the Company (hereinafter called the “Notes”) issued under the Indenture.

The Notes may be redeemed, as a whole or in part, at the Company’s option, at any time or from time to time, upon notice (by mail, electronic delivery or otherwise in accordance with the depositary’s procedures) not less than 10 days nor more than 60 days prior to the date fixed for redemption to holders of the Notes. Prior to the Par Call Date, the redemption price (expressed as a percentage of principal amount and rounded to three decimal places) for the Notes will be equal to the greater of:

plus, in either case, accrued interest, if any, to the redemption date.

On and after the Par Call Date, the redemption price for the Notes will be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued interest, if any, to the redemption date.

“Par Call Date” means August 9, 2051 (six months prior to the maturity date of the Notes).

“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 daily 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). 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.

If on the third Business Day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual 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 prices 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 semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices, 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 shall not be responsible or liable for any calculation of the redemption price or of any component thereof, or for determining whether manifest error has occurred.

On and after the redemption date, interest will cease to accrue on the Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the redemption price and accrued interest. On or before the redemption date, the Company will deposit with a Paying Agent, or the Trustee, money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $100,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

In case an Event of Default with respect to the Notes, as defined in the Indenture, shall have occurred and be continuing, the principal hereof together with interest accrued thereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

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 Securities at the time outstanding of all series to be affected (acting as one class), to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Securities of such series to be affected; provided however, that no such supplemental indenture shall, among other things, (i) change the fixed maturity of the principal of, or any installment of principal of or interest on, or the currency of payment of, any Security; (ii) reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof; (iii) impair the right to institute suit for the enforcement of any such payment on or after the fixed maturity thereof (or, in the case of redemption, on or after the redemption date); (iv) reduce the percentage in principal amount of the outstanding Securities of any series, the consent of whose holders is required for any such supplemental indenture, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture; (v) change any obligation of the Company, with respect to outstanding Securities of a series, to maintain an office or agency in the places and for the purposes specified in the Indenture for such series; or (vi) modify any of the foregoing provisions or the provisions for the waiver of certain covenants and defaults, except to increase any applicable percentage of the aggregate principal amount of outstanding Securities the consent of the holders of which is required or to provide with respect to any particular series the right to condition the effectiveness

of any supplemental indenture as to that series on the consent of the holders of a specified percentage of the aggregate principal amount of outstanding Securities of such series or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each outstanding Security affected thereby. It is also provided in the Indenture that the holders of a majority in aggregate principal amount of the Securities of a series at the time outstanding may on behalf of the holders of all the Securities of such series waive any past default under the Indenture with respect to such series and its consequences, except a default in the payment of the principal of, premium, if any, or interest, if any, on any Security of such series or in respect of a covenant or provision which cannot be modified without the consent of the Holder of each outstanding Security of the series affected. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

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

The Indenture permits the Company to Discharge its obligations with respect to the Notes on the 91st day following the satisfaction of the conditions set forth in the Indenture, which include the deposit with the Trustee of money or U.S. Government Obligations or a combination thereof sufficient to pay and discharge each installment of principal of (including premium, if any, on) and interest, if any, on the outstanding Notes.

If the Company shall, in accordance with Section 901 of the Indenture, consolidate with or merge into any other corporation or convey or transfer its properties and assets substantially as an entirety to any Person, the successor shall succeed to, and be substituted for, the Person named as the “Company” on the face of this Note, all on the terms set forth in the Indenture.

The Notes are issuable in registered form without coupons in denominations of $100,000 and any integral multiple of $1,000 in excess thereof. In the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge, Notes may be exchanged for an equal aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company maintained for such purpose in the Borough of Manhattan, The City and State of New York.

Upon due presentation for registration of transfer of this Note at the office or agency of the Company for such registration in the Borough of Manhattan, The City and State of New York, or any other office or agency designated by the Company for such purpose, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange herefor, subject to the

limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving payment of the principal of, premium, if any, and interest on this Note, as herein provided, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice of the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability for moneys payable on this Note.

No recourse for the payment of the principal of, premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, 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.

Unless otherwise defined in this Note, all terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
