(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 First 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 First 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 First 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 this 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 3.05 of this First Supplemental Indenture to promptly execute and deliver to the Trustee a Supplemental Indenture substantially in the form set forth in Exhibit B to this First 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.

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 mailed to the Holders of the Notes, with a copy provided to the Trustee.
