annum until the principal hereof is paid or made available for payment. The first Interest Payment Date for the Securities of this series shall be December 1, 2020, and interest on the Securities of this series will accrue from and including
June 3, 2020, to and excluding the first Interest Payment Date, and thereafter will accrue from and including the last Interest Payment Date to which interest on the Securities of this series has been paid or duly provided for. No interest will

 In the event that any Interest Payment Date is not a Business Day, then payment of interest
payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on the Interest Payment Date. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid (a) to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on the May 15 or November 15, whether or not a Business Day (each such date, a “Regular Record Date”), immediately preceding such Interest Payment Date or (b) so long as the Bonds are Global Bonds held in the name
of a securities depository for the Bonds or its nominee, to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Business Day immediately preceding such Interest Payment Date,
except that interest payable at Maturity will be payable to the Person to whom principal shall be paid. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and
may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture referred to herein. Interest on this Security will be computed on the basis of a 360-day year of twelve 30-day months. 
 Payment of the principal
of and premium, if any, and interest at Maturity on this Security shall be made upon presentation of this Security at the corporate trust office of The Bank of New York Mellon in New York, New York, or at such other office or agency as may be

Security (other than interest payable at Maturity) shall be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, provided that if such Person is a securities depositary, such
payment may be made by such other means in lieu of check as shall be agreed upon by the Company, the Trustee and such Person. 
 This
Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and issuable in one or more series under an Indenture, dated as of October 1, 2010 (herein called the “Original
Indenture” and, together with any amendments or supplements thereto and the Officer’s Certificate establishing the terms of the Securities of this series, the “Indenture,” which term shall have the meaning assigned to it in the
Original Indenture), between the Company and The Bank of New York Mellon, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including
Supplemental Indenture No. 8 thereto, for a statement of the property mortgaged, pledged and held in trust, the nature and extent of the security, the conditions upon which the lien of the Indenture may be released and the respective rights,

option of the Company, in whole at any time or in part from time to time, at a redemption price equal to the greater of:

	 	(b)	 as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of
principal and interest on the principal amount of this Security to be so redeemed that would be due if the Stated Maturity Date of this Security were the Par Call Date (not including any portion of such payments of interest accrued to the date of
redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 30
basis points, 


 plus, in either of the above cases, accrued and unpaid interest to the date of redemption. 

Promptly after the calculation thereof, the Company shall give the Trustee written notice of the redemption price for the foregoing

having an actual or interpolated maturity comparable to the remaining term of this Security (assuming for this purpose that the Stated Maturity Date of this Security were the Par Call Date) that would be utilized, at the time of selection and in

 Notice of redemption
shall be given by mail to Holders of Securities, not less than 30 days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company
as aforesaid may state that such redemption shall be conditional upon the receipt by the applicable Paying Agent or Agents of money sufficient to pay the principal of and premium, if any, and interest, on this Security on or prior to the date fixed
for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security. 

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

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.
