ARTICLE ONE

SCOPE OF ELEVENTH SUPPLEMENTAL INDENTURE

Section 1.01. Scope. This Eleventh Supplemental Indenture constitutes an integral part of the Indenture and this Eleventh Supplemental Indenture shall be read together with the Indenture as though all the provisions thereof are contained in one instrument. Except as expressly amended by this Eleventh Supplemental Indenture, the terms and provisions of the Indenture shall remain in full force and effect.

Section 1.02. Definitions.

(a) “Guarantee” means any guarantee by a Guarantor of the Notes or other Securities that may be issued under the Indenture, executed pursuant to the terms of the Indenture, as amended or supplemented from time to time.

(b) “Guarantors” means (i) with respect to each Series of the Notes, (A) initially, the Initial Guarantors and (B) each of the Company’s other subsidiaries that executes a Guarantee of the Notes of such Series pursuant to the terms of the Indenture, as amended or supplemented from time to time, and (ii) with respect to other Securities that may be issued under the Indenture, each of the Company’s subsidiaries that executes a Guarantee of such Securities pursuant to the terms of the Indenture, as amended or supplemented from time to time; provided that, upon release or discharge of such Person from its Guarantee in accordance with the provisions of the Indenture, as amended or supplemented from time to time, such Person shall cease to be a Guarantor.

(c) Any capitalized term used in this Eleventh Supplemental Indenture and not defined herein that is defined in the Indenture shall have the meaning specified in the Indenture, unless the context shall otherwise require.

ARTICLE TWO

GUARANTEES OF THE NOTES

Section 2.01. Unconditional Guarantees. Each Guarantor hereby unconditionally, jointly and severally, and irrevocably guarantees (each such guarantee to be referred to herein as a Guarantee) to each Holder of the Notes and its successors and assigns, that: (i) the principal of and interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration or otherwise and interest on the overdue principal, if any, and interest on any interest of the Notes and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder, will be promptly paid in full

3

or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise, subject, however, to the limitations set forth in Section 2.04. Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives 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, subject to Section 2.03, this Guarantee will not be discharged except by complete performance of the obligations of the Company contained in the respective Notes and the Indenture with respect to the respective Series of Notes. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee.

Section 2.02. Severability. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 2.03. Release of a Guarantor; Termination of Guarantee. Upon (i) subject to Section 2.05, the sale or disposition (whether by merger, stock purchase, asset sale or otherwise) of a Guarantor (or all or substantially all its assets or its Capital Stock) to an entity which is not (after giving effect to such transaction) a Restricted Subsidiary and which sale or disposition is otherwise in compliance with the terms of the Indenture, (ii) the Legal Defeasance of the respective Series of Notes and the Guarantees, or (iii) the designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of the Indenture, then in each such case such Guarantor shall be deemed automatically and unconditionally released and discharged from all the Guarantor’s obligations under the Guarantee with respect to the Notes (or respective Series thereof) without any further action required on the part of the Guarantor, the Company, the Trustee or any Holder. In the event of a transfer of all or substantially all of the assets or Capital Stock of such Guarantor, unless required pursuant to Section 2.05(a)(1), the Person acquiring such assets or stock of such Guarantor shall not be subject to the Guarantor’s obligations under the Guarantee with respect to any Notes.

4

An Unrestricted Subsidiary that is a Guarantor shall be deemed automatically and unconditionally released and discharged from all obligations under this Article Two upon notice from the Company to the Trustee to such effect, without any further action required on the part of the Guarantor, the Company, the Trustee or any Holder.

The Guarantee with respect to any Series of Notes shall terminate and be of no further force or effect upon the redemption in full, retirement or other discharge of such Series of Notes.

The Trustee shall deliver an appropriate instrument evidencing any such release upon receipt of a request by the Company accompanied by an Officers’ Certificate and Opinion of Counsel certifying as to the compliance with this Section 2.03.

Any Guarantor not released in accordance with this Section 2.03 remains liable for the full amount of principal of and interest on the Securities as provided in this Article Two.

Section 2.04. Limitation of a Subsidiary Guarantor’s Liability. Notwithstanding anything contained herein to the contrary, it is the intention of the parties that the guarantee by each Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the foregoing intention, the parties hereby irrevocably agree that the obligations of each Guarantor under its Guarantee of the Notes shall be limited to the maximum amount as will, 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 or pursuant to Section 2.06), result in the obligations of such Guarantor under its Guarantee not constituting such fraudulent transfer or conveyance.

Section 2.05. Guarantors May Consolidate, etc., on Certain Terms.

(a) No Guarantor may transfer all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor in a transaction to which subsection (b) applies, unless:

(1) the Person acquiring the property in any such transfer or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture (including its Guarantee of the Notes) pursuant to an agreement reasonably satisfactory to the trustee;

(2) such transfer, consolidation or merger is not an Asset Disposition and the Person acquiring such assets, or surviving such consolidation or merger, is not a Restricted Subsidiary; or

(3) such transfer, consolidation or merger is an Asset Disposition that complies with Section 6.05 of the Fourth, Fifth, Sixth, Seventh, Eighth, Ninth and Tenth Supplemental Indentures, as applicable.

5

(b) Nothing contained in the Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Restricted Subsidiary that is a Guarantor, or shall prevent any sale of assets or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Restricted Subsidiary that is a Guarantor. Upon any such consolidation, merger, sale or conveyance between a Guarantor and the Company or another Guarantor, the Guarantee with respect to the Notes given by the non-surviving or transferring Guarantor in the transaction shall no longer have any force or effect.

Section 2.06. Contribution. In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that in the event any payment or distribution is made by any Guarantor (a “Funding Guarantor”) under its Guarantee with respect to the Notes, such Funding Guarantor shall be entitled to a contribution from all other Guarantors in a pro rata amount based on the Adjusted Net Assets of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to any Notes or any other Guarantor’s obligations with respect to the Guarantee of the Notes. “Adjusted Net Assets” of such Guarantor at any date shall mean the lesser of the amount by which (x) the fair value of the property of such Guarantor exceeds the total amount of liabilities, including, without limitation, contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any other Subsidiary of the Guarantor in respect of the obligations of its Guarantee of the Notes), but excluding liabilities under the Guarantee of the Notes, of such Guarantor at such date and (y) the present fair salable value of the assets of such Guarantor at such date exceeds the amount that will be required to pay the probable liability of such Guarantor on its debts (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any other Subsidiary of the Company in respect of the obligations of such Guarantor under its Guarantee of the Notes), excluding debt in respect of the Guarantee of the Notes of such Guarantor, as they become absolute and matured.

Section 2.07. Waiver of Subrogation. Until all guaranteed obligations under the Indenture and with respect to all Notes are paid in full, 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 the Guarantee of the Notes 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 of the Notes, 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 2.07 is knowingly made in contemplation of such benefits.

6

Section 2.08. Execution of Guarantee. To evidence their guarantee to the Holders of the Notes, the Guarantors hereby agree to execute the Guarantee in substantially the form included in Exhibit B. Each Guarantor hereby agrees that its Guarantee set forth in this Article Two shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee. Such signatures upon the Guarantee may be by manual or facsimile signature of such officers and may be imprinted or otherwise reproduced on the Guarantee.

Section 2.09. Compensation and Indemnity. Each of the Guarantors agrees to jointly and severally, with the Company, indemnify the Trustee as set forth in Section 7.07 of the Original Indenture.

Section 2.10. Legal Defeasance. Section 8.01(b) of the Original Indenture is hereby amended by deleting it in its entirety and inserting in lieu thereof the following:

Upon the Company’s exercise under paragraph (a) of the option applicable to this paragraph (b), the Company and each of the Guarantors shall be deemed to have been released and discharged from its obligations with respect to the outstanding Securities of a Series (including Guarantees) on the date the applicable conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company and each Guarantor shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities of a Series (including Guarantees), which shall thereafter be deemed to be “outstanding” only for the purposes of the Sections and matters under this Indenture referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Securities, the Guarantees and this Indenture insofar as such Securities and Guarantees are concerned, except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Securities of a Series to receive solely from the trust fund described in paragraph (d) below and as more fully set forth in such paragraph, payments in respect of the principal of and interest on such Securities when such payments are due and (ii) obligations listed in Section 8.02, subject to compliance with this Section 8.01. The Company may exercise its option under this paragraph (b) notwithstanding the prior exercise of its option under paragraph (c) below with respect to such Securities and Guarantees.

Section 2.11. Event of Default. In addition to the Events of Default specified in the Indenture, it shall constitute an Event of Default if, except as permitted by the Indenture, any Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Guarantee.
