		Authorized Signatory

This Note is one of a duly authorized issue of debt securities (the “Securities”) of the Company, of a series designated as its 2.400% Notes due August 15, 2026 (herein called the “Notes”), issued and to be issued under the Indenture, to which Indenture and all relevant indentures supplemental thereto reference is hereby made for a statement of the respective rights, obligations, duties and immunities thereunder of the Company, the Trustee, the Bank and the Securityholders and the terms upon which the Notes are, and are to be, authenticated and delivered. The Securities, of which the Notes constitute a series, 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 be subject to different covenants and Events of Default and may otherwise vary as provided in the Indenture. All capitalized terms not otherwise defined herein shall have the definitions assigned to them in the Indenture.

The Company is not required to repurchase Notes from holders prior to Stated Maturity.

In the event of redemption of this Note in part only, a new Note or Notes of this series, having the same Stated Maturity, optional redemption provisions, Interest Rate and other terms and provisions of this Note, in authorized denominations in an aggregate principal amount equal to the unredeemed portion hereof will be issued in the name of the holder hereof upon the surrender hereof.

As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note may be registered on the register of the Notes, upon surrender of this Note for registration of transfer at the Bank, or at such other agencies as may be designated pursuant to the Indenture, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Trustee or the Bank duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Notes are issuable as registered Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of other authorized denominations having the same interest rate, Stated Maturity, optional redemption provisions, if any, and Original Issue Date, as requested by the Security holder surrendering the same.

No service charge will 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.

The Company, the Trustee, the Bank, the Security registrar and any agent of the Company, the Trustee, the Bank, or the Security registrar may treat the Security holder in whose name this Note is registered as the absolute owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Note is overdue, and neither the Company, the Trustee, the Bank, the Security registrar nor any such agent shall be affected by notice to the contrary.

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

The Indenture also permits the Company and the Trustee to enter into supplemental indentures without the consent of the holders of Securities of any series for certain purposes specified in the Indenture, including the making of such other provisions in regard to matters arising under the Indenture which shall not adversely affect the interest of the holders of such Securities. The Indenture also contains provisions permitting the holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the holders of all the 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 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.

The Indenture provides that no holder of any Security of any series may enforce any remedy with respect to such series under the Indenture except in the case of refusal or neglect of the Trustee to act after notice of a continuing Event of Default and after written request by the holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series and the offer to the Trustee of reasonable indemnity; provided, however, that such provision shall not prevent the holder hereof from enforcing payment of the principal of or interest on this Note.
