The interest so payable, and punctually paid or duly provided for, on any Fixed Rate Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the May 1 and November 1, whether or not a Business Day, next preceding such Fixed Rate Interest Payment Date.

The interest so payable, and punctually paid or duly provided for, on any Floating Rate Interest Payment Date, other than on the Maturity Date, will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be August 1, 2022, November 1, 2022 and February 1, 2023, whether or not both a London Business Day or a Business Day, next preceding such Floating Rate Interest Payment Date.

Any such interest not so punctually paid or duly provided for on such Fixed Rate Interest Payment Date or Floating Rate Interest Payment Date shall 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 said Indenture.

Payment of the principal of (and premium, if any) and any such interest on this Security will be made at the office or agency of the Company maintained for that purpose in the City of Boston, Massachusetts, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, that for so long as this Security is a Global Security, payment of the principal of (and premium, if any) and any interest on this Security will be made by the Paying Agent by wire transfer in immediately available funds in U.S. dollars at the office of the Paying Agent; provided further, that, in the case of payments made at maturity of such Global Security, the Global Security is presented to the Paying Agent in time for the Paying Agent to make such payments in accordance with its normal procedures.

Interest on this Security during the Fixed Rate Period shall be paid on the basis of a 360-day year consisting of twelve 30-day months. If a Fixed Rate Interest Payment Date for this Security falls on a day that is not a Business Day, the Company shall postpone the interest payment to the next succeeding Business Day, but the payments made on such dates shall be treated as being made on the date that the payment was first due, and Holders of Securities of this series shall not be entitled to any further interest or other payments with respect to such postponement.

The initial interest period during the Floating Rate Period for this Security is the period from and including May 15, 2022 to, but excluding, the next Interest Reset Date (as defined below), and subsequent interest periods during the Floating Rate Period will be the periods from and including an Interest Reset Date to, but excluding, the next Interest Reset Date or Maturity Date, as applicable. Interest on this Security during the Floating Rate Period will be computed on the basis of a 360-day year for the actual number of days elapsed. Interest will be reset on August 15, 2022, November 15, 2022 and February 15, 2023 (each, an “Interest Reset Date”). If an Interest Reset Date for this Security falls on a day that is not both a Business Day and a London Business Day, then such date will be postponed to the next day that is both a Business Day and a London Business Day, except that, if the next such date falls in the next calendar month, then such date will be advanced to the immediately preceding day that is both a Business Day and a London Business Day. For interest periods during the Floating Rate Period, LIBOR will be determined by the calculation agent on the second London Business Day immediately preceding the first day of such interest period in the following manner:

The calculation agent is State Street Bank and Trust Company unless and until such time as a successor is appointed. The Company may appoint a different institution to serve as calculation agent from time to time after the original issue date of this Security without the consent of holders of this Security and without notice. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any interest period, will be on file at the Company’s principal offices, will be made available to any noteholder upon request and will be final and binding in the absence of manifest error.

A “Business Day” means any day other than a Saturday, Sunday or other day on which banking institutions in The City of New York or The City of Boston are authorized or required by law or executive order to remain closed.

A “London Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in London generally are authorized or obligated by law, regulation or executive order to close and, in the case of any debt security for which LIBOR is an interest rate basis, is also a day on which dealings in the applicable index currency are transacted in the London interbank market.

A “Representative Amount” means an amount that, in the calculation agent’s judgment, is representative of a single transaction in the relevant market at the relevant time.

The “Reuters screen” means the display on the Reuters 3000 Xtra service, or any successor or replacement service.

All percentages resulting from any calculation of the interest rate on this Security during the Floating Rate Period will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

The interest rate on this Security during the Floating Rate Period will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

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 October 31, 2014 (herein called the “Base Indenture”), between the Company and U.S. Bank National Association, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented by a First Supplemental Indenture, dated as of May 8, 2017, between the Company and the Trustee (the “First Supplemental Indenture” and together with the Base Indenture, herein called 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, and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.

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.

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.

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.
