Securities of this series are 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 March 25, 1998 (as supplemented, herein called the “Indenture”), between the Company and U.S. Bank National Association, as successor trustee to Wachovia Bank, National Association (formerly First Union National Bank) (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which the Indenture and all indentures supplemental thereto, including, the Eighteenth Supplemental Indenture thereto, dated as of March 3, 2020, between the Company and the Trustee, 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 authenticated and delivered. Capitalized terms used but not defined herein have the meanings set forth in the Indenture. In the event of a conflict, the terms of the Indenture shall govern to the extent lawful. This Security is one of the series designated as the “3.100% Notes due 2050” therein, initially having an aggregate principal amount equal to $                ; provided, that the Company may, without the consent of the Holders of the then Outstanding 3.100% Notes, “reopen” this series of Securities so as to increase the aggregate principal amount of 3.100% Notes Outstanding in compliance with the procedures set forth in the Indenture, including Sections 3.1 and 3.3 thereof, so long as any such additional notes have the same tenor and terms (including, without limitation, rights to receive accrued and unpaid interest) as the 3.100% Notes then Outstanding.

Securities of this series may be redeemed prior to October 15, 2049, at any time at the option of the Company, in whole or in part from time to time, upon notice of not more than 60 nor less than 15 days prior to the Redemption Date, at a redemption price equal to the greater of (i) 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date and (ii) the Make-Whole Amount, if any, set forth in the Indenture, plus accrued and unpaid interest thereon to, but not including the Redemption Date, with respect to the 3.100% Notes; provided, however, that if the Company

redeems the 3.100% Notes on or after October 15, 2049, the redemption price will equal 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date.

The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of the Company on this Security and (ii) certain restrictive covenants and the related defaults and Events of Default applicable to the Company, in each case, upon compliance by the Company with certain conditions set forth in the Indenture, which provisions apply to this Security.

If an Event of Default with respect to the Securities shall occur and be continuing, the principal of the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

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 thereunder, unless (i) such Holder shall have previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities, (ii) 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 (iii) 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 interest on or after the respective due dates expressed herein.

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 not less than a majority in principal amount of the Outstanding Securities of all Securities then Outstanding affected thereby. 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 herefor 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 interest on (or Make-Whole Amount, if any, with respect to) this Security at the times, place and rate, and in the coin or currency, herein prescribed.

This 3.100% Note is a Global Security. As provided in and subject to the provisions of the Indenture, definitive Securities shall be issued to all owners of beneficial interests in a Global Security in exchange for such interests if: (1) the depositary with respect to the 3.100% Notes (which shall initially be DTC) notifies the Company that it is unwilling or unable to continue as depositary for such Global Security or the depositary ceases to be a clearing agency registered under the Exchange Act, at a time when the depositary is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice; (2) an Event of Default has occurred and is continuing and the Security Registrar has received a request from the depositary or (3) the Company executes and delivers to the Trustee and Security Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable. In connection with the exchange of an entire Global Security for definitive Securities pursuant to this paragraph, such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute and the Trustee shall authenticate and deliver, to each beneficial owner identified by the depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of definitive Securities of authorized denominations.

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.
