WHEREAS, pursuant to Section 901(3) of the Original Indenture, the parties hereto desire to enter into this Second Supplemental Indenture to evidence the full and unconditional Guarantee (as defined below) by the Parent Guarantor of all obligations of the Existing Obligors under the Debentures and the Original Indenture;

WHEREAS, all actions necessary to make this Second Supplemental Indenture the valid and binding obligation of the Parent Guarantor and to constitute this document a valid and binding supplemental indenture according to its terms have been duly taken;

ARTICLE II

Agreement to Guarantee

SECTION 2.01. The Guarantee. Subject to the provisions of this Article 2, the Parent Guarantor hereby fully and unconditionally guarantees the due and punctual payment of the principal of (and premium, if any) and interest on, and any other amounts payable under the Original Indenture and the Debentures, when and as the same shall become due and payable, whether at maturity, a specified payment date, upon acceleration, redemption or otherwise, according to the terms thereof (the “Guarantee”). In the case of any failure by the Existing Obligors (which term includes any successor Person under the Original Indenture) to make punctually any such payment of the principal of and, premium, if any, and interest on and any other amounts payable in respect of the Debentures, the Parent Guarantor hereby agrees to cause any such payment to be made punctually when and as the same shall become due and payable, whether at maturity, a specified payment date, upon acceleration, redemption or otherwise, according to the terms thereof, and as if such payment were made by the Parent Guarantor.

SECTION 2.02. Ranking. The Guarantee shall be the Parent Guarantor’s senior unsecured obligation and shall rank equally in right of payment with all of its other senior and unsecured debt obligations.

SECTION 2.03. Guarantee Unconditional. The Parent Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by: any invalidity, irregularity, illegality or unenforceability of any Debenture, any incapacity or lack or limitations of powers, authority of the Existing Obligors or of the Existing Obligors’ directors, officers, employees, agents or representatives; any failure to enforce the provisions of the Debentures; any waiver, modification, release, discharge or indulgence granted to the Existing Obligors with respect thereto, by any holder of the Debentures; the entry of any judgment against the Existing Obligors; the initiation or pendency of any proceedings with respect to the Existing Obligors under any applicable bankruptcy, liquidation, insolvency, reorganization or other similar law; or any other circumstance that may otherwise constitute a legal defense of, or equitable discharge to, the Parent Guarantor; provided, however, that no such waiver, modification or indulgence shall, without the consent of the Parent Guarantor, increase the principal of any Debenture, or increase the premium, if any, or the interest rate thereon or alter the maturity date thereof.

SECTION 2.04. Waiver by Parent Guarantor; Discharge Only Upon Payment in Full. Provided that any Holder of Debentures shall have made a request (oral or written) to the Existing Obligors for payment (which procedural requirement to make such a request shall not apply in the event of the initiation or pendency of any proceedings with respect to the Existing Obligors under any applicable bankruptcy, liquidation, insolvency, reorganization or other similar law), the Parent Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger or bankruptcy of the Existing Obligors, any right to require a proceeding first against the Existing Obligors, protest or notice with respect to any or all Debentures or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged except by payment in full of the principal of, and premium, if any, and interest on and other amounts payable in respect of the Debentures. A Holder need not exhaust any recourse that it may have against the Existing Obligors or other Persons before being entitled to full payment from the Parent Guarantor under the Guarantee.

2

SECTION 2.05. Payment Guarantee. The Guarantee is a guarantee of payment and not of collection.

SECTION 2.06. Subrogation. The Parent Guarantor shall be subrogated to all rights of the Holder of any Debenture against the Existing Obligors in respect of any amounts paid to such Holder by the Parent Guarantor pursuant to the provisions of the Guarantee; provided, however, that the Parent Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon such right of subrogation until the principal of and, premium, if any, and interest on and any other amounts payable in respect of any Debenture shall have been paid in full.

SECTION 2.07. Reinstatement. If any Holder is required by any court or otherwise to return to the Existing Obligors or the Parent Guarantor (or any trustee, liquidator, custodian or other similar official acting in relation to either the Existing Obligors or the Parent Guarantor) any amount paid by the Existing Obligors or the Parent Guarantor to such Holder, the Guarantee shall be reinstated in full force and effect to the extent theretofore discharged.

SECTION 2.08. Notation of Guarantee Not Required. The Parent Guarantor acknowledges that the Guarantee shall remain in full force and effect notwithstanding the absence on any Debenture of a notation relating to the Guarantee.

SECTION 2.09. Release of the Parent Guarantor.

(a) The Parent Guarantor’s obligations under the Guarantee shall terminate and be automatically released without the need for any action by any party:

(b) Upon delivery by the Existing Obligors to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect and reasonably satisfactory to the Trustee, the Trustee shall execute any documents (in form and substance reasonably satisfactory to the Trustee) reasonably required in order to evidence the release of the Parent Guarantor pursuant to this Section 2.09 from its obligations under the Guarantee.

SECTION 2.10. Benefits Acknowledged.
