The Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Indenture or any series of Securities, the absence of any action to enforce the same, any waiver or consent by any Holder or the Trustee with respect to any provisions of the Indenture, any series of Securities or of this Agreement, 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 the Guarantor. The 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 proceeding first against the Company, protest, notice and all demands whatsoever and covenants that the Guarantee will not be discharged except by complete performance of the obligations contained in the Indenture and each series of Securities. If any Holder or Trustee is required by any court or otherwise to return to the Company or the Guarantor or any custodian, trustee, liquidator or other similar official acting in relation to the Company or the Guarantor, any amount paid by the Company or Guarantor to the Trustee or such Holder, the Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

Each such Guarantee shall be signed on behalf of the Guarantor by its Chairman of the Board, its President or one of its Vice Presidents prior to the authentication of the Security on which it is endorsed, and the delivery of such Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of such Guarantee on behalf of the Guarantor. Such signature upon the Guarantee may be a manual or facsimile signature of such officer and may be imprinted or otherwise reproduced on the Guarantee, and in case such officer who shall have signed the Guarantee shall cease to be such officer before the Security on which Guarantee is endorsed shall have been authenticated and delivered by the Trustee or disposed of by the Company, the Security nevertheless may be authenticated and delivered or disposed of as though the Person who signed the Guarantee had not ceased to be such officer of the Guarantor.

SECTION 2.03. Subordination of Subrogation and Other Rights. The Guarantor hereby agrees that any claim against the Company that arises from the payment, performance or enforcement of the Guarantor’s obligations under the Guarantee or the Indenture, including, without limitation, any right of subrogation, shall be subject and subordinate to, and no payment with respect to any such claim of the Guarantor shall be made before, the payment in full in cash of all outstanding Securities of each series in accordance with the provisions provided therefor in the Indenture.

ARTICLE IV

(b) modify any of the provisions of this Section 4.02, except to increase any such percentage or to provide that certain other provisions of this Agreement cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby.

An amendment that changes or eliminates any covenant or other provision of this Agreement which has expressly been included solely for the benefit of one or more particular series of Securities, or that modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Agreement of the Holders of Securities of any other series.

It shall not be necessary for any Act of Holders under this Section 4.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such Act shall approve the substance thereof.

SECTION 4.03. Execution of Amendments. In executing any amendment permitted by this Article IV, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement.
