RECITALS OF THE COMPANY

The Company, the Guarantor and the Trustee entered into an Indenture dated as of December 8, 2016 (the “Original Indenture”), pursuant to which senior unsecured debentures, notes or other evidences of indebtedness of the Company (the “Securities”), which may be convertible into or exchangeable for any securities of any Person (including the Company), may be issued in one or more series from time to time.

Section 3.01 of the Original Indenture permits the terms of any series of Securities to be established in an indenture supplemental to the Original Indenture.

Section 9.01 of the Original Indenture provides that a supplemental indenture may be entered into by the Company, the Guarantor and the Trustee without the consent of any Holders of the Securities for certain purposes stated therein.

The Company and the Guarantor have requested the Trustee to join with each of them in the execution and delivery of this First Supplemental Indenture in order to supplement the Original Indenture by, among other things, establishing certain terms of two series of Securities to be known as (x) the Company’s “4.011% Senior Notes due 2026” (the “2026 Notes”) and (y) “5.031% Senior Notes due 2046” (the “2046 Notes” and, together with the 2026 Notes, the “Notes”), in each case to be fully and unconditionally guaranteed by the Guarantor (the “Guarantees”) and adding certain provisions thereof for the benefit of the Holders of the Notes.

The Company has furnished the Trustee with a duly authorized and executed Company Order dated December 8, 2016 authorizing the execution of this First Supplemental Indenture and the issuance of the Notes. Such Company Order is sometimes referred to herein as the “Authentication Order.”

All things necessary to make this First Supplemental Indenture a valid agreement of the Company, the Guarantor and the Trustee and a valid supplement to the Original Indenture have been done.

NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH:

For and in consideration of the premises and the purchase of the Notes to be issued hereunder by Holders thereof, the Company, the Guarantor and the Trustee mutually covenant and agree, for the equal and proportionate benefit of the respective Holders from time to time of the Notes, as follows:

-11-

This restriction will not apply to indebtedness secured by (i) Liens on any shares of stock or indebtedness of or acquired from a Person that is merged or consolidated with or into, or is otherwise acquired by, the Company, the Guarantor or any Designated Subsidiary, (ii) Liens to secure indebtedness of a Designated Subsidiary to the Company, the Guarantor or another Designated Subsidiary (but only for so long as such indebtedness is owned or held by the Company, the Guarantor or another Designated Subsidiary) and (iii) any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in clauses (i) or (ii) above.


SECTION 10.08.	Limitation on the Disposition of Stock of Designated Subsidiaries.

So long as any Notes are Outstanding, the Guarantor will not, nor will the Guarantor permit any Designated Subsidiary to issue, sell, assign, transfer or otherwise dispose of any shares of Capital Stock of any Designated Subsidiary (other than to the Company, the Guarantor or another Designated Subsidiary); provided, however, that the foregoing shall not apply to any issuance, sale, assignment, transfer or disposition of Capital Stock (i) required by any law, regulation or order of any court, or governmental or insurance regulatory authority, unless any such order was requested by the Company, the Guarantor or any of the Designated Subsidiaries, (ii) for fair market value, as determined in good faith by the Guarantor’s board of directors or (iii) to the Guarantor or any of its Subsidiaries.”

(b) For purposes only of the Notes and Sections 10.07 and 10.08 of the Original Indenture, the following terms shall have the following meanings:

“Capital Stock” of any Person means any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests in (however designated) equity of such person, including preferred stock, in each case, which are entitled to vote in the election of directors, member or general partners or other similar managing body, as applicable, but excluding any debt securities convertible into or other securities convertible into such equity; provided, however, that preferred shares or other similar securities issued in the ordinary course of business by any of the Company’s Subsidiaries in

For purposes of the Indenture and the Notes, Section 5.02 of the Original Indenture is hereby amended in its entirety and replaced with the following:

SECTION 5.02 Acceleration of Maturity; Rescission and Annulment.

If an Event of Default (other than with respect to an Event of Default described in Section 8.1(7) or 8.1(8) of the Indenture) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company and the Guarantor (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

In the case of an Event of Default described in Section 8.1(7) or 8.1(8) of the Indenture, which occurs and is continuing with respect to Securities of any series at the time Outstanding, then all unpaid principal of and accrued interest on all such Outstanding Securities of that series shall become immediately due and payable without any notice or other action on the part of the Trustee or the Holders of any Securities of such series.

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the

-15-

money due has been obtained by the Trustee, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company, the Guarantor and the Trustee, may rescind and annul such declaration and its consequences if:


(1)	the Company or the Guarantor has paid or deposited with the Trustee a sum sufficient to pay:

(D) all sums paid or advanced by the Trustee and any predecessor Trustee hereunder and all sums due the Trustee and any predecessor Trustee under Section 6.07;

and

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.

No such rescission shall affect any subsequent default or impair any right consequent thereon.
