SUBSIDIARY GUARANTEES

Section 8.01. Guarantees.

(a) Each of the Guarantors, as primary obligor and not merely as surety, hereby jointly and severally, irrevocably and fully and unconditionally guarantees to each Holder and to the Trustee and its successor and assigns (each, a “Guarantee”), on a senior unsecured basis and equal in right of payment to all existing and future senior indebtedness of such Guarantors, the punctual payment when due of all monetary obligations of the Company under the Indenture and the Notes, whether for principal of or interest on the Notes.

(b) The obligations of each Guarantor shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee, result in the obligations of such Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law, or being void or unenforceable under any law relating to insolvency of debtors.

(c) Each Guarantor further agrees that (to the fullest extent permitted by law) its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Indenture, the Notes or the obligations of the Company or any other Guarantor hereunder or thereunder, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same, or any other circumstance that might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(d) Each Guarantor hereby waives (to the fullest extent permitted by law) the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that (except as otherwise provided in Section 8.03 of this Sixth Supplemental Indenture) its Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and the Guarantee. Such Guarantee is a guarantee of payment and not of collection.

Section 8.02. Continuing Guarantee.

(a) Each Guarantee shall be a continuing Guarantee and shall, (i) subject to Section 8.03 of this Sixth Supplemental Indenture, remain in full force and effect until payment in full of the principal amount of all outstanding Notes (whether by payment at maturity, purchase, redemption, defeasance, retirement or other acquisition), (ii) be binding upon such Guarantor and (iii) inure to the benefit of and be enforceable by the Trustee, the Holders and their permitted successors, transferees and assigns.

(b) The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced or terminated the obligations of any Guarantor hereunder and under its Guarantee (whether such payment shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or any Guarantor or otherwise, all as though such payment had not been made.

Section 8.03. Release of Guarantee. Notwithstanding the provisions of Section 8.02 of this Sixth Supplemental Indenture, a Guarantor shall be automatically and unconditionally released from its obligations under the indenture upon:

(a) the sale or other disposition of such Guarantor;

(b) the sale or disposition of all or substantially all of the assets of such Guarantor;

(c) the Company’s exercise of its legal defeasance option or its covenant defeasance option as described in Article 10 of the Base Indenture or if the Company’s obligations under the Indenture are discharged in accordance with the terms of the Indenture; or

(d) delivery of an Officer’s Certificate to the Trustee that such Guarantor does not guarantee the obligations of the Company under any indebtedness for money borrowed of the Company and that any other guarantees of such Guarantor have been released other than through discharges as a result of payment by such Guarantor on such guarantees,

provided, however, that in the case of clauses (a) and (b) above, (1) such sale or other disposition is made to a Person other than the Company or one of its subsidiaries and (2) such sale or disposition is otherwise permitted by the Indenture. Upon any such occurrence specified in this Section 8.03, at the Company’s

request, and upon delivery to the Trustee of an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent under the Indenture relating to such release have been complied with, the Trustee shall execute any documents reasonably requested by the Company evidencing such release.

Section 8.04. Notation Not Required. Neither the Company nor any Guarantor shall be required to make a notation on the Notes to reflect any Guarantee or any release thereof.

Section 8.05. Waiver of Subrogation. Each Guarantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under its Guarantee and the Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Notes against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and the Notes shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Holders, and shall forthwith be paid to the Trustee for the benefit of such Holders to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of the Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and that the waiver set forth in this Section 8.05 is knowingly made in contemplation of such benefits.

Section 8.06. Execution and Delivery of Guarantees. The Company shall cause each subsidiary that is required to become a Guarantor pursuant to Section 3.04 of this Sixth Supplemental Indenture to promptly execute and deliver to the Trustee a Supplemental Indenture substantially in the form set forth in Exhibit B to this Sixth Supplemental Indenture, or otherwise in form and substance reasonably satisfactory to the Trustee, evidencing its Guarantee on substantially the terms set forth in this Article 8. Concurrently therewith, the Company shall deliver to the Trustee an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee to the effect that such Supplemental Indenture has been duly authorized, executed and delivered by such subsidiary and that, subject to applicable bankruptcy, insolvency, fraudulent transfer, fraudulent conveyance, reorganization, moratorium and other laws now or hereafter in effect affecting creditors’ rights or remedies generally and to general principles of equity (including standards of materiality, good faith, fair dealing and reasonableness), whether considered in a proceeding at law or at equity, such Supplemental Indenture is a valid and binding agreement of such subsidiary, enforceable against such subsidiary in accordance with its terms.

Section 8.07. Notices. Notice to any Guarantor shall be sufficient if addressed to such Guarantor care of the Company at the address, place and manner provided in Section 11.04 of the Base Indenture.

ARTICLE 9

[REVERSE OF NOTE]

This Note is one of the duly authorized securities of the Company (herein called the “Notes”) issued and to be issued in one or more series under an Indenture, dated as of May 3, 2010 (as supplemented from time to time heretofore, the “Base Indenture”), as supplemented by a Sixth Supplemental Indenture, dated as of November 3, 2016 (the “Sixth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company, the guarantors party thereto (the “Guarantors”) and U.S. Bank National Association, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of Notes represented hereby), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is a Global Note representing the Company’s 3.000% Notes due 2023 in the aggregate principal amount of $350,000,000.

The amount of interest payable on any interest payment date shall be computed on the basis of a 360-day year consisting of twelve 30-day months. In the event that any date on which interest is payable on this Note is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on such interest payment date.

The Notes of this series are issuable only in fully registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 above that amount.

The Notes shall be redeemable, at the option of the Company, at any time and from time to time, in whole or in part, on not less than 30 nor more than 60 days’ prior notice transmitted to the Holders of the Notes, with a copy provided to the Trustee. The Redemption Price of the Notes shall be calculated as follows:

(i) 100% of the principal amount of the Notes to be redeemed; and

plus, in each case, accrued and unpaid interest on the Notes to be redeemed to the date of redemption.

A-3

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company.

“Primary Treasury Dealer” means a primary U.S. government securities dealer in the United States.

On and after any redemption date, interest will cease to accrue on the Notes called for redemption. On or before the redemption date, the Company shall deposit with the Trustee or with one or more paying agents an amount of money sufficient to redeem on the redemption date all of the Notes so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If the Company is redeeming less than all of the Notes, (a) if the Notes are represented by global notes, interests in the global notes will be selected for redemption in accordance with the customary procedures of DTC, or (b) if the Notes are represented by Notes in certificated form, the Trustee must select the Notes to be redeemed by such method as the Trustee deems fair and appropriate in accordance with methods generally used at the time of selection by fiduciaries in similar circumstances.

Upon the occurrence of a Change of Control Triggering Event with respect to the Notes, unless the Company has exercised its right to redeem the Notes as described above by giving irrevocable notice to the Trustee in accordance with the Indenture, each Holder of Notes shall have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

A-4

Unless the Company has exercised its right to redeem the Notes, within 30 days following the date upon which the Change of Control Triggering Event occurs with respect to the Notes or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall be required to send a notice to each Holder of Notes, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent, other than as may be required by law (the “Change of Control Payment Date”). The notice, if sent prior to the date of consummation of the Change of Control, shall state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Company shall, to the extent lawful: (i) accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; (ii) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased and that all conditions precedent to the Change of Control Offer and to the repurchase by the Company of Notes pursuant to the Change of Control Offer have been complied with.

The Company shall not be required to make a Change of Control Offer with respect to the Notes if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer.

The Company shall comply in all material respects with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

“Change of Control” means the occurrence of any of the following after the Issue Date:

A-5

(d) the adoption of a plan relating to the Company’s liquidation or dissolution.

The indebtedness evidenced by this Note is, to the extent provided in the Indenture, the senior and unsecured obligation of the Company and will rank equally in right of payment to all of the Company’s existing and future senior unsecured and unsubordinated indebtedness. This Note will, to the extent provided in the Indenture, be guaranteed, jointly and severally, by each of the Guarantors party to the Indenture on a senior unsecured basis. This Note may hereafter be entitled to certain other Guarantees made for the benefit of the Holders. Reference is made to Article 8 of the Sixth Supplemental Indenture for terms relating to such Guarantees, including the release, termination and discharge thereof. Neither the Company nor any Guarantor shall be required to make any notation on this Note to reflect any Guarantee or any such release, termination or discharge.

The Notes are initially limited to $350,000,000 aggregate principal amount. The Company may from time to time, without notice to or the consent of the Holders of the Notes, create and issue additional Notes ranking equally and ratably with the Notes of this series in all respects (other than the issue price, the date of the issuance, the payment of interest accruing prior to the issue date of such additional Notes and the first payment of interest following the issue date of such additional Notes), provided that such Notes must be part of the same issue as the Notes initially issued for U.S. federal income tax purposes. Any such additional Notes shall be consolidated and form a single series with the Notes initially issued, including for purposes of voting and redemptions.

The Notes are not entitled to the benefit of any sinking fund.

The Indenture imposes certain limitations on the ability of the Company to, among other things, merge or consolidate with any other Person, and requires that the Company comply with certain further covenants, such as Limitations on Liens and Limitations on Sale and Leaseback Transactions as further described in the Indenture, all of which are applicable to this Note. All such covenants and limitations are subject to a number of important qualifications and exceptions.

The Indenture contains provisions for the defeasance at any time of (a) the entire indebtedness of the Company on this Note and (b) certain restrictive covenants and the related defaults and Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of the Notes of this series may (subject to the conditions set forth in the Indenture) be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture contains provisions permitting, with certain exceptions therein provided, the Company and the Trustee, without the consent of any of the Holders of the outstanding Notes, to modify and amend the Indenture for the purpose of, among other things, curing any ambiguity, defect or inconsistency.

A-7

The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the outstanding Notes, on behalf of the Holders of all Notes, to waive any past default or Event of Default with respect to the Notes and its consequences, except a default in the payment of the principal of or interest on any of the Notes or in respect of a covenant or other provision which, under the terms of the Indenture, cannot be modified or amended without the consent of the Holder of each outstanding Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the currency, herein prescribed.

No director, officer, employee, incorporator or stockholder, as such, of the Company, any Guarantor or any other obligor in respect of any Note or any subsidiary of any thereof shall have any liability for any obligation of the Company, any Guarantor or any other obligor in respect of any Note under the Indenture, the Notes or any Guarantee, or for any claim based on, in respect of, or by reason of, any such obligation or its creation.
