NOW, THEREFORE, in consideration of the above premises, each party agrees, for the benefit of the others and for the equal and ratable benefit of the Holders, as follows:

Section 1.01 Securities Guarantee.

(a)Each of the New Guarantors hereby fully and unconditionally guarantees the Obligations (collectively, the “Additional Guarantees” and, each, an “Additional Guarantee”), on a joint and several basis with the Current Guarantors, to each Holder of the Notes and to the Trustee and its successors and assigns on behalf of each Holder of the Notes. Each New Guarantor further agrees that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from such New Guarantor and that such New Guarantor will remain bound under this Article I notwithstanding any extension or renewal of any Obligation. All payments under each Additional Guarantee will be made as specified in Section 311 of the Base Indenture.

(b)Each New Guarantor hereby agrees that its obligations hereunder shall be as if it were principal debtor and not merely surety and shall be absolute, full and unconditional, unaffected by, and irrespective of, any invalidity, irregularity or unenforceability of the Notes, the Base Indenture or this Supplemental Indenture, any failure to enforce the provisions of the Notes, the Base Indenture or this Supplemental Indenture, any waiver, modification or indulgence granted to the Company with respect thereto by the Holders of the Notes or the Trustee, or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor (except payment in full). Each New Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger or bankruptcy of the Company, any right to require that the Trustee pursue or exhaust its legal or equitable remedies against the Company prior to exercising its rights under an Additional Guarantee (including, for the avoidance of doubt, any right which a New Guarantor may have to require the seizure and sale of the assets of the Company to satisfy the outstanding principal of, interest on or any other amount payable under the Notes prior to recourse against such New Guarantor or its assets), protest or notice with respect to the Notes or the Debt evidenced thereby and all demands whatsoever, and covenants that its Additional Guarantee will not be discharged with respect to the Notes except by payment in full of the principal thereof and interest thereon or as otherwise provided in the Base Indenture or in this Supplemental Indenture, including Section 1.04 herein. If at any time any payment of principal of (and premium, if any) and interest on the Notes is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of any New Guarantor’s obligations hereunder with respect to such payment shall be reinstated as of the date of such rescission, restoration or return as though such payment had become due but had not been made at such times.

Neither a failure nor a delay on the part of either the Trustee or the Holders of the Notes in exercising any right, power or privilege under this Article I shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders of the Notes expressed in this Article I are cumulative and exclusive of any other rights, remedies or benefits that either may have under this Article I at law, in equity, by statute or otherwise.

(c)Each New Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder of the Notes in enforcing any rights under this Section 1.01.

(d)Upon request of the Trustee, each New Guarantor shall execute and deliver such instruments and do such further acts as may be reasonably necessary to give effect to this Supplemental Indenture.

(a)Each New Guarantor shall be subrogated to all rights of the Holders of the Notes against the Company in respect of any amounts paid to such Holders of the Notes by such New Guarantor pursuant to the provisions of its Additional Guarantee.

(b)Each New Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders of the Notes in respect of any Obligations guaranteed hereby until payment in full of all Obligations. Each New Guarantor further agrees that, as between it, on the one hand, and the Holders of the Notes and the Trustee, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Section 502 of the Base Indenture for the purposes of the Additional Guarantees herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Section 502 of the Base Indenture, such Obligations shall forthwith become due and payable by the New Guarantor for the purposes of this Section 1.02.

Section 1.03Release of Guarantee. An Additional Guarantee of a New Guarantor shall be automatically and unconditionally released, and the New Guarantor that granted such Additional Guarantee shall be automatically and unconditionally released from its Obligations:

(a)in the event that all of the capital stock or other equity interests, or all or substantially all of the assets, of such New Guarantor are sold or transferred, including by way of merger, consolidation or otherwise, in a transaction in compliance with the terms of the Indenture;

(b)upon defeasance as provided in Sections 7.01 and 7.02 or satisfaction and discharge of the Indenture as provided in Article 4 of the Base Indenture;

(c)upon redemption of the Notes as provided in Section 3.1 of the Indenture; or

(d)upon release of such New Guarantor’s Additional Guarantee of all indebtedness under the Credit Agreement other than a release by or as a result of payment under such Additional Guarantee.

Section 1.04Limitation and Effectiveness of Guarantees. Each Additional Guarantee is limited to an amount not to exceed the maximum amount that can be guaranteed by such New Guarantor that gave such Additional Guarantee without rendering such Additional

Guarantee, as it relates to such New Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally or the maximum amount otherwise permitted by law.

Section 2.04Successors. All agreements of each New Guarantor in this Supplemental Indenture and the Notes shall bind its successors. All agreements of the Trustee in this Supplemental Indenture and the Notes shall bind its successors.
