The Notes (together with the Trustee’s certificate of authentication) shall be substantially in the form ofExhibit A hereto, which is hereby incorporated in and made a part of this Supplemental Indenture.

The Notes will be issued in the form of fully registered global securities without coupons (“Global Notes”) that will be deposited with, or on behalf of, DTC, and registered in the name of DTC’s partnership nominee, Cede & Co. Except under the circumstance described below, the Notes will not be issuable in definitive form. Unless and until it is exchanged in whole or in part for the individual Notes represented thereby, a Global Note may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee of DTC to a successor depositary or any nominee of such successor.

So long as DTC or its nominee is the registered owner of a Global Note, DTC or such nominee, as the case may be, will be considered the sole owner or Holder of the Notes represented by such Global Note for all purposes under this Supplemental Indenture. Except as described below, owners of beneficial interest in Notes evidenced by a Global Note will not be entitled to have any of the individual Notes represented by such Global Note registered in their names, will not receive or be entitled to receive physical delivery of any such Notes in definitive form and will not be considered the owners or Holders thereof under the Indenture or this Supplemental Indenture.

If DTC is at any time unwilling, unable or ineligible to continue as depositary and a successor depositary is not appointed by the Company within 90 days, the Company will issue individual Notes in exchange for the Global Note or Global Notes representing such Notes. In addition, the Company may at any time and in its sole discretion, subject to certain limitations set forth in the Indenture, determine not to have any of such Notes represented by one or more Global Notes and, in such event, will issue individual Notes in exchange for the Global Note or Global Notes representing the Notes. Individual Notes so issued will be issued in minimum denominations of $2,000 and integral multiples of $1,000.

(b)Interest and Interest Rate. The Notes will bear interest at a rate of 2.700% per annum, from December 16, 2019 (or, in the case of Notes issued upon the reopening of this series of Notes, from the date designated by the Company in connection with such reopening) or from the immediately preceding Interest Payment Date to which interest has been paid or duly provided for, payable semi-annually in arrears on each of February 15 and August 15, commencing August 15, 2020 (each of which shall be an “Interest Payment Date”), to the Persons in whose names the Notes are registered in the Security Register at the close of business on February 1 or August 1, as the case may be (whether or not a Business Day), next preceding such Interest Payment Date (each, a “Regular Record Date”).

(c)Principal Repayment; Currency. The Notes will mature on February 15, 2027, provided, however, the Notes may be earlier redeemed at the option of the Company as provided in paragraph (d) below.

The Notes will be subject to redemption at the option of the Company, at any time in whole or from time to time in part, upon not less than 15 nor more than 30 days’ notice transmitted to each Holder of Notes to be redeemed as shown in the Security Register. If the Notes are redeemed, the redemption price will equal to the sum of (i) 100% of the principal amount of the Notes (or portion of such Notes) being redeemed plus accrued and unpaid interest thereon to but excluding the redemption date and (ii) the Make-Whole Amount, if any; provided, however, that if the Notes are redeemed on or after the Par Call Date, the redemption price will equal 100% of the principal amount of the Notes (or portion of such Notes) being redeemed plus accrued and unpaid interest thereon to but excluding the redemption date. Notwithstanding the foregoing, the Company will pay any interest installment due on an Interest Payment Date which occurs on or prior to a redemption date to the Holders of the Notes as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date. The Company shall calculate the redemption price. The election to redeem the Notes may be evidenced by either a Board Resolution or an Officers’ Certificate.

[Form of Reverse of Security]

1.General. This Security is 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 15, 2010 (as amended, supplemented or otherwise modified from time to time, the “Base Indenture”), as supplemented by Supplemental Indenture No. 17, dated as of December 16, 2019 (as amended, supplemented or otherwise modified from time to time, the “Supplemental Indenture” and the Base Indenture, as supplemented by such Supplemental Indenture, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Debt and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

2.Optional Redemption. The Securities of this series are subject to redemption, at any time or from time to time, as a whole or in part, at the election of the Company. If the Securities of this series are redeemed, the redemption price will equal to the sum of (i) 100% of the principal amount of the Securities (or portion of such Securities) being redeemed plus accrued and unpaid interest thereon to but excluding the redemption date and (ii) the Make-Whole Amount, if any; provided, however, that if the Securities are redeemed on or after the Par Call Date, the redemption price will equal 100% of the principal amount of the Securities (or portion of such Securities) being redeemed plus accrued and unpaid interest thereon to but excluding the redemption date. Notwithstanding the foregoing, the Company will pay any interest installment due on an Interest Payment Date which occurs on or prior to a redemption date to the Holders of the Notes as of the close of business on the Notes Regular Record Date immediately preceding such Interest Payment Date. The Company shall calculate the redemption price. The election to redeem the Securities may be evidenced by either a Board Resolution or an Officers’ Certificate.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

3.Defeasance. The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

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

5.Actions of Holders. 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 Securities at the time Outstanding of each series to be affected. 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 therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

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 such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than a majority 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 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 premium or interest hereon on or after the respective due dates expressed herein.

6.Payments Not Impaired. 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 any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

7.Denominations, Transfer, Exchange. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

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.
