NOW, THEREFORE, in order to declare the terms and conditions upon which the Notes are executed, registered, authenticated, issued and delivered, and in consideration of the foregoing premises and the purchase of such Notes by the Holders thereof, the Company and the Trustee mutually covenant and agree, for the equal and proportionate benefit of the Holders from time to time of the Notes, as follows:

Section 1.Definitions. Terms used in this Supplemental Indenture and not defined herein shall have the respective meanings given such terms in the Base Indenture.

Section 2.Creation and Authorization of Series.

(a)There is hereby created and authorized the following two new series of Securities to be offered and issued under the Base Indenture, to be designated as the:


(i)			“4.050% Notes due 2030”
(ii)			“4.700% Notes due 2050”

(b)The 2030 Notes shall be limited initially to $1,250,000,000 in aggregate principal amount and the 2050 Notes shall be limited initially to $750,000,000 in aggregate principal amount. Notwithstanding the foregoing initial aggregate principal amounts, the Company may, from time to time and without consent of any Holders of the Notes, re-open any series of Notes on terms identical in all respects to the outstanding Notes of such series (except for the date of issuance, the date interest begins to accrue and, in certain circumstances, the first interest payment date), so that such additional notes shall be consolidated with, form a single series with and increase the aggregate principal amount of the Notes of such series; provided, that the additional notes shall have a separate CUSIP number unless: (i) the additional notes and the outstanding Notes of the original series are treated as part of the same “issue” of debt instruments for U.S. federal income tax purposes, (ii) the additional notes are issued pursuant to a “qualified reopening” of the outstanding Notes of the original series for U.S. federal income tax purposes or (iii) the additional notes are, and the outstanding Notes of the original series were, issued without or with less than a de minimis amount of original issue discount for U.S. federal income tax purposes. Such additional notes shall have the same terms as to ranking, redemption, guarantees, waivers, amendments or otherwise, as the applicable series of Notes, and will vote together as one class on all matters with respect to such series of Notes.

(c)The form of security for the 2030 Notes is Exhibit A-1 and the form of security for the 2050 Notes is Exhibit A-2.

(d)The date on which the principal is payable on each series of the Notes, unless accelerated pursuant to the terms of the Indenture, shall be as provided in the applicable form of security attached hereto as Exhibit A-1 or Exhibit A-2.

(e)The Notes of each series shall bear interest as provided in the applicable form of security attached hereto as Exhibit A-1 or Exhibit A-2. The Interest Payment Dates, and the Regular Record Dates for the determination of Holders of the Notes to whom such interest is

DMEAST #40573469 v2

(f)The Notes will be the Company’s direct unsecured general obligations and will rank equally with all of its existing and future unsecured and unsubordinated debt, will be senior in right of payment to all of its existing and future subordinated debt and will be junior to any of its future secured debt to the extent of the value of the collateral securing such secured debt.

(g)The Notes of each series will be issued only in fully registered form, without coupons, in denominations provided herein and in the applicable form of security attached hereto as Exhibit A-1 or Exhibit A-2.

(h)The Notes shall be subject to the Events of Default provided in Section 5.1 of the Base Indenture. For purposes of the Notes (but not other Securities, unless provided by the terms thereof), an “Event of Default” shall also include:

As used above, “Indebtedness” means all obligations for borrowed money.

(i)The discharge, defeasance and covenant defeasance provisions that will apply to the Notes shall be as provided in the Base Indenture.

(j)The Notes of each series shall be issued in the form of one or more Registered Global Securities substantially in the applicable form of security attached hereto as Exhibit A-1 or Exhibit A-2. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Notes of each series. Additional provisions applicable to the Notes issued in the form of a Registered Global Security are set forth in the applicable form of security attached hereto as Exhibit A-1 or Exhibit A-2.

(k)The Notes shall be issuable only in minimum denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

(l)The Trustee will initially act as the Paying Agent with respect to the Notes of each series. The office of the Paying Agent will be located at 0 Xxxxx XxXxxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxxxxx 00000.

“Comparable Treasury Price” means, with respect to any redemption date, the average of the Reference Treasury Dealer Quotations (as defined below) for such redemption date.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company at 3:30 p.m. New York City time on the third Business Day preceding such redemption date.

DMEAST #40573469 v2

The Company shall have the right to redeem the 2030 Notes at any time on or after January 15, 2030 (three months prior to the maturity of the 2030 Notes) or the 2050 Notes at any time on or after October 15, 2049 (six months prior to the maturity date of the 2050 Notes), in each case, in whole or in part, at its option, upon at least 15 days’ and not more than 60 days’ notice, at a redemption price, as calculated by the Company, equal to 100% of the principal amount of the notes then outstanding to be redeemed plus accrued and unpaid interest on the principal amount being redeemed to but excluding the redemption date. The Trustee shall have no obligation to calculate or verify any redemption price or premium (if any).

Any optional redemption may be conditioned upon the consummation of one or more other transactions, including any debt or equity issuance by the Company or any of its parent companies or Subsidiaries.
