At the option of the Company, interest may be paid by check to the Person entitled thereto at his last address as it appears on the registry books, and principal may be paid by check to the registered Holder hereof or other Person entitled thereto against surrender of this Note.

This Note is one of a duly authorized issue of notes (hereinafter called the “Securities”) of the Company of the Series hereinafter specified, which Series is as of the date of original issuance of this Note limited in the aggregate principal amount to $500,000,000, all such Securities issued or to be issued under and pursuant to an Indenture dated as of October 12, 2017, as supplemented by a First Supplemental Indenture dated as of October 12, 2017 (hereinafter referred to as the “Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee (hereinafter referred to as the “Trustee” which term shall also include any successor or co-trustee under the Indenture), to which Indenture reference is hereby made for a statement of the rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. As provided in the Indenture, the Securities may be issued in one or more Series, which different Series may be issued in various aggregate principal amounts, may be denominated in currencies other than Dollars (including composite currencies), may mature at different times, may bear interest, if any, at different rates, may be subject to different redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided or permitted. This Note is one of a series of Global Notes (each a “Global Note”) which represent all of the Company’s Floating Rate Notes due 2020 (the “Notes”). Provided the Company complies with the requirements of the Indenture, the Company may, without the consent of the Holders of the Notes, create and issue additional Notes ranking equally with the Notes and otherwise similar in all respects so that such further Notes would be consolidated and form a single series of Securities.

No mandatory redemption obligation will be applicable to the Notes. The Notes will not be subject to, nor have the benefit of, a sinking fund. Additionally, the Company does not have a right to redeem the Notes prior to maturity. If a Change of Control Triggering Event occurs, the Company shall be required to make an offer to each Holder of the Notes to repurchase such Holder’s Notes on the terms set forth in the Indenture.

The Indenture contains provisions for defeasance and discharge at the Company’s option of the entire principal of all the Securities of any Series upon compliance by the Company with certain conditions set forth therein.

If an Event of Default with respect to the Notes, as defined in the Indenture, shall occur and be continuing, the principal of all the Notes may be declared, or shall ipso facto become, as applicable, due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification or elimination of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time outstanding, of all Series to be affected thereby, voting together as a single class. It is also provided in the Indenture that, with respect to certain defaults or Events of Default regarding the Securities of any Series, prior to any declaration accelerating the maturity of such Securities, the Holders of a majority in aggregate principal amount of the Securities of all Series at the time outstanding with respect to which an Event of Default shall have occurred and be continuing voting together as a single class may on behalf of the Holders of all the Securities of such Series waive any such past default or Event of Default and its consequences. The preceding sentence shall not, however, apply to a default in the payment of the principal of or interest on any of the Securities. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note 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 Note.

No reference herein to the Indenture and no provision of this Global Note 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 this Global Note at the times, place and rate, and in the coin or currency, herein prescribed.

This Note is a Global Note registered in the name of Cede & Co., as nominee of the Depositary. Beneficial interests in this Note will be shown on, and transfers thereof will be effected only through, records maintained by the Depositary and the participants of the Depositary. Except as described below, Notes in certificated form will not be issued in exchange for this Global Note.

If the Depositary for the Notes represented by this Global Note is at any time unwilling or unable to continue as Depositary or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, a successor Depositary registered as a clearing agency under the Exchange Act is not appointed by the Company within ninety days or an Event of Default has occurred and is continuing with respect to the Notes, the Company shall issue such Notes in definitive form in exchange for this Global Note. In addition, the Company

may at any time and in its sole discretion, but subject to the procedures of the Depositary, determine not to have the Notes represented by one or more Global Notes and, in such event, shall issue Notes in definitive form in exchange for the Global Note or Notes representing the Notes.

The Notes are issuable only in registered form without coupons in denominations of $2,000 and multiples of $1,000 in excess of $2,000.

This Note shall for all purposes be governed by, and construed in accordance with, the laws of the State of New York.

The Company, the Trustee and any agent of the Company or such Trustee may treat the Person in whose name this Note is registered as the owner hereof for the purpose of receiving payment as herein provided, subject to the record date provisions of this Note, and for all other purposes, whether or not this Note be overdue and notwithstanding any notation of ownership or other writing thereon and neither the Company, such Trustee nor any such agent shall be affected by notice to the contrary.

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, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.
