RECITALS OF THE COMPANY

WHEREAS, Section 901(5) of the Indenture permits supplements thereto without the consent of Holders of Securities to change any provisions of the Indenture with respect to a series of Securities, where there are no Securities Outstanding which are entitled to the benefit of such provision; and

WHEREAS, as contemplated by Section 301 of the Indenture, the Company intends to issue from time to time two new series of Securities consisting of 3.250% Senior Notes due 2023 (the “Senior Notes”) and 4.875% Senior Debentures due 2043 (the “Senior Debentures”) under the Indenture;

NOW, THEREFORE, THIS FIFTEENTH SUPPLEMENTAL INDENTURE WITNESSETH:

For consideration, the adequacy and sufficiency of which are hereby acknowledged by the parties hereto, each party agrees as follows, for the benefit of the other

party and for the equal and proportionate benefit of all Holders of the Senior Notes and Senior Debentures as follows:

SECTION 1. For the purpose of this Fifteenth Supplemental Indenture, all terms used herein, unless otherwise defined, shall have the meaning assigned to them in the Indenture, as supplemented hereby.

SECTION 2. For the sole benefit of the Holders of the Senior Notes and the Senior Debentures:

SECTION 2.1 The Company shall issue the Senior Notes in an initial aggregate principal amount of $300,000,000 and the Senior Debentures in an initial aggregate principal amount of $250,000,000 on the date hereof. The forms of the Senior Notes and the Senior Debentures are set forth in Exhibit A and Exhibit B hereto, respectively. The Senior Notes and the Senior Debentures shall include the legends set forth on the face of Exhibit A and Exhibit B hereto, respectively, substantially in the form so set forth, except to the extent otherwise provided herein.

SECTION 2.2 The Senior Notes and the Senior Debentures shall each be issued initially in the form of one or more permanent global Securities, in registered form substantially in the form set forth in Exhibit A and Exhibit B hereto, respectively (together, the “Global Securities”), registered in the name of the nominee of The Depository Trust Company, as U.S. Depositary, deposited with the Trustee, as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as provided in Section 303 of the Indenture. The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary or its nominee, in accordance with the instructions given by the Holder thereof, as hereinafter provided.

SECTION 2.3 Section 1101 of the Indenture is hereby deleted in its entirety and replaced by the following Section 1101:

SECTION 1101. Optional Redemption. The Senior Notes and/or Senior Debentures will be redeemable, in accordance with this Article Eleven, at any time, at the option of the Company, in whole or from time to time in part, upon not less than 30 nor more than 60 days’ prior notice, on any date on or after December 15, 2022, in the case of the Senior Notes, and on or after December 15, 2042, in the case of the Senior Debentures, to their maturity at a Redemption Price equal to the sum of 100% of the principal amount thereof and any accrued and unpaid interest, to the Redemption Date (subject to the rights of holders of record on the relevant Regular Record Date that is on or prior to the Redemption Date to receive interest due on the relevant Interest Payment Date). The Company shall mail notice of any such redemption at least 30 days, but not more than 60 days, before the Redemption Date to each Holder of the Senior Notes or Senior Debentures, as the case may be, to be redeemed.

The Senior Notes and/or Senior Debentures will be redeemable, in accordance with this Article Eleven, at any time, at the option of the Company, in whole or from time to time in part, upon not less than 30 nor more than 60 days’ prior notice, on any date prior to December 15, 2022, in the case of the Senior Notes, and prior to December 15, 2042, in the case of the Senior Debentures, at a Redemption Price equal to the sum of 100% of the principal amount thereof and the Make-Whole Amount and any accrued and unpaid interest, to the Redemption Date (subject to the rights of holders of record on the relevant Regular Record Date that is on or prior to the Redemption Date to receive interest due on the relevant Interest Payment Date). The Make-Whole Amount with respect to such a redemption shall be calculated by an independent investment banking institution of national standing appointed by the Company. If, for purposes of calculating the Make-Whole Amount, the Reinvestment Rate shall not be available as set forth in the definition thereof, the Reinvestment Rate shall be calculated by interpolation or extrapolation of comparable rates selected by the independent investment banking institution.

For purposes of this Section 1101, the term “Make-Whole Amount” means the excess, if any, of (i) the aggregate present value as of the Redemption Date of the principal being redeemed and the amount of interest (exclusive of interest accrued to the Redemption Date) that would have been payable if redemption had not been made, determined by discounting, on a semiannual basis, the remaining principal and interest at the Reinvestment Rate described below (determined on the third business day preceding the Redemption Date) from the dates on which the principal and interest would have been payable if the redemption had not been made, to the Redemption Date, over (ii) the aggregate principal amount of such Senior Notes or Senior Debentures, as the case may be.

For purposes of this Section 1101, the term “Reinvestment Rate” means (i) the arithmetic mean of the yields under the heading “Week Ending” published in the most recent Federal Reserve Statistical Release H.15 (or any comparable successor publication) under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month) corresponding to the remaining life to Maturity, as of the payment date of the principal being redeemed or paid, plus (ii) 0.20%, in the case of the Senior Notes, or 0.25%, in the case of the Senior Debentures. If no maturity exactly corresponds to the Maturity, yields for the two published maturities most closely corresponding to the Maturity shall be so calculated and the Reinvestment Rate shall be interpolated or extrapolated, as the case may be, on a straight-line basis, rounding to the nearest month. The most recent Federal Reserve Statistical Release H.15 published prior to the date of determination of the Make-Whole Amount shall be used for purposes of calculating the Reinvestment Rate.

SECTION 2.4 Section 101 of the Indenture is hereby amended by adding the following definitions, each in appropriate alphabetical order:

“Below Investment Grade Rating Event” with respect to the Senior Notes or Senior Debentures, as the case may be, means that such Senior Notes or Senior Debentures become rated below Investment Grade by all of the Rating Agencies on any

date from the date of the public notice of an arrangement that results in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of such Senior Notes or Senior Debentures, as the case may be, is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

(1)

the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Company and those of the subsidiaries of the Company, taken as a whole, to any “person” (individually and as that term is used in Section 13(d)(3) and Section 14(d)(2) of the Exchange Act), other than the Company or one of its Affiliates;

(2)

the first day on which a majority of the members of the Board of Directors of the Company are not Continuing Directors;

(3)

(4)

the consummation of a so-called “going private/Rule 13e-3 Transaction” that results in any of the effects described in paragraph (a)(3)(ii) of Rule 13e-3 under the Exchange Act (or any successor provision) with respect to each class of the Company’s common stock, following which Redstone Family Members beneficially own, directly or indirectly, more than 50% of the Voting Stock of the Company, measured by voting power rather than the number of shares.

As used in this definition of “Change of Control,” an “Affiliate” of the Company means any Person directly or indirectly controlling, controlled by or under direct or indirect common control with the Company, or directly or indirectly controlled by a Redstone Family Member, and “Voting Stock,” as applied to stock of any Person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such Person having ordinary voting power for the election of a majority of the directors (or the equivalent) of such Person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

(2)

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s), BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch) (or, in each case, if such Rating Agency ceases to rate the Senior Notes or Senior Debentures, as the case may be, for reasons outside of the Company’s control, the equivalent investment grade credit rating from any Rating Agency selected by the Company as a replacement Rating Agency).

“Redstone Family Members” includes only the following persons: (i) Mr. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, (ii) the estate of ▇▇. ▇▇▇▇▇▇▇▇; (iii) each descendant of ▇▇. ▇▇▇▇▇▇▇▇ or spouse or former spouse of ▇▇. ▇▇▇▇▇▇▇▇ and their respective estates, guardians, conservators or committees; (iv) any spouse or former spouse of ▇▇. ▇▇▇▇▇▇▇▇; (v) each “Family Controlled Entity” (as defined below); and (vi) the trustees, in their respective capacities as such, of each “Family Controlled Trust” (as defined below).

by Redstone Family Members; and (iv) any limited liability or similar company if more than 50% of the value of the company is owned by Redstone Family Members. The term “Family Controlled Trust” includes certain trusts existing on March 11, 2013 and any other trusts the primary beneficiaries of which are Redstone Family Members, spouses of Redstone Family Members and/or charitable organizations, provided that if the trust is a wholly charitable trust, more than 50% of the trustees of such trust consist of Redstone Family Members.

“S&P” means Standard & Poor’s Ratings Services, a division of The ▇▇▇▇▇▇-▇▇▇▇ Companies, Inc.

SECTION 2.5 The following Section 1108 is hereby added to the Indenture:

SECTION 1108. Change of Control. (a) Upon the occurrence of a Change of Control Repurchase Event in respect of the Senior Notes or Senior Debentures, the Company shall make an offer to each holder of such Senior Notes and/or Senior Debentures as to which the Change of Control Repurchase Event has occurred to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such holder’s Senior Notes and Senior Debentures pursuant to the offer described in this Section 1108 (the “Change of Control Offer”) at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Price”). Within 30 days following any Change of Control Repurchase Event in respect of the Senior Notes and/or Senior Debentures, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change of Control, the Company shall mail a notice to each holder describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Senior Notes or Senior Debentures, as the case may be, on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

(b) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Senior Notes or Senior Debentures as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Senior Notes or Senior Debentures, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Senior Notes or Senior Debentures by virtue of such conflict.

(1)

accept for payment all Senior Notes and Senior Debentures or portions of Senior Notes and Senior Debentures properly tendered pursuant to the Company’s offer;

(2)

deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Senior Notes and Senior Debentures or portions of Senior Notes and Senior Debentures properly tendered; and

(3)

deliver or cause to be delivered to the Trustee the Senior Notes and Senior Debentures properly accepted, together with an officers’ certificate stating the aggregate principal amount of the Senior Notes and Senior Debentures being purchased by the Company.

(d) The Paying Agent shall promptly pay, from funds deposited by the Company for such purpose, to each holder of Senior Notes and Senior Debentures properly tendered the purchase price for the Senior Notes and Senior Debentures, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Senior Note and/or Senior Debenture equal in principal amount to any unpurchased portion of Senior Notes and Senior Debentures surrendered, as the case may be.

(e) The Company shall not be required to make an offer to repurchase the Senior Notes or Senior Debentures subject to any Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Senior Notes and Senior Debentures properly tendered and not withdrawn under its offer.

SECTION 2.6 The following Section 305A is hereby added to the Indenture:

SECTION 305A. Book-Entry Provisions for Global Securities. (a) Each Global Security initially shall (i) be registered in the name of the Depositary for such Global Security or the nominee of such Depositary, (ii) be delivered to the Trustee, as custodian for such Depositary, and (iii) bear legends as set forth on the face of the form of the Senior Note or of the form of the Senior Debenture, as applicable.

Members of, or Participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Security.

(b) Transfers of a Global Security shall be limited to transfers of such Global Security in whole, but not in part, to the Depositary, its successors or their respective nominees. Transfers of interests in one Global Security to parties who will hold the interests through the same Global Security will be effected in the ordinary way in accordance with the rules and operating procedures of the applicable Depositary. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” of Euroclear and the “General Terms and Conditions of Clearstream” and “Customer Handbook” of Clearstream shall be applicable to interests in the Global Securities that are held by Agent Members through Euroclear and Clearstream.

(c) Any beneficial interest in one of the Global Securities that is transferred to a person who takes delivery in the form of an interest in another Global Security will, upon transfer, cease to be an interest in such Global Security and become an interest in such other Global Security and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for so long as it remains such an interest.

(d) In connection with any transfer of a portion of the interests in a Global Security to beneficial owners pursuant to paragraph (c) of this Section 305A, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the interest in such Global Security to be transferred.

(e) In connection with the transfer of the Global Securities, in whole, to beneficial owners pursuant to paragraph (b) of this Section 305A, the Global Securities shall be deemed to be surrendered to the Trustee for cancellation.

(f) The registered holder of a Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Senior Notes and Senior Debentures.

(g) The Senior Notes and Senior Debentures are initially solely issuable as Global Securities. Registered Securities shall be physically transferred to all beneficial owners in definitive form in exchange for their beneficial interests in a Global Security, if the Depositary with respect to such Global Securities notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security, as the case may be, and a successor Depositary is not appointed by the Company within 90 days of such notice.

(h) All Senior Notes and Senior Debentures issued upon any transfer or exchange of Senior Notes and Senior Debentures shall be valid, legally enforceable obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Senior Notes and Senior Debentures surrendered upon such transfer or exchange.

SECTION 3. THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN THIS FIFTEENTH SUPPLEMENTAL INDENTURE.

SECTION 4. This Fifteenth Supplemental Indenture may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original, but such counterparts shall together constitute but one and the same instrument.

SECTION 5. Except as herein amended with respect to the Senior Notes and the Senior Debentures, all applicable terms, conditions and provisions of the Indenture, as supplemented, shall continue in full force and effect and shall remain binding and enforceable in accordance with their respective terms.

SECTION 6. The Trustee makes no representations as to the validity or sufficiency of this Supplemental Indenture. The recitals and statements herein are deemed to be those of the Company and not of the Trustee.

IN WITNESS WHEREOF, the parties have caused this Fifteenth Supplemental Indenture to be duly executed, all as of the day and year first written above.
