SECTION 1.20. Guarantee.

Article Fourteen of the Indenture is hereby amended by replacing Article Fourteen with the following:

“ARTICLE FOURTEEN
GUARANTEES OF SECURITIES

Section 14.1. Unconditional Guarantees.

For value received, each Guarantor hereby fully, irrevocably, unconditionally and absolutely guarantees to the Holders of Securities of each series to which this Article Fourteen has been made applicable as provided in Section 3.1(22) and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on such Securities, and all other amounts due and payable under this Indenture and such Securities by the Company to the Trustee or such Holders (including, without limitation, all costs and expenses (including reasonable legal fees and disbursements) incurred by the Trustee or such Holders in connection with the enforcement of this Indenture and the Guarantees) (collectively, the “Indenture Obligations”), when and as such principal, premium, if any, interest, if any, and other amounts shall become due and payable, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, according to the terms of such Securities and this Indenture. The guarantees by the Guarantors set forth in this Article Fourteen are referred to herein as the “Guarantees". Without limiting the generality of the foregoing, the Guarantors’ liability shall extend to all amounts that constitute part of the Indenture Obligations and would be owed by the Company to the Trustee or such Holders under this Indenture and such Securities but for the fact that they are unenforceable, reduced, limited, impaired, suspended or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Company.

Failing payment when due of any amount guaranteed pursuant to the Guarantees, for whatever reason, each Guarantor will be obligated (to the fullest extent permitted by applicable law) to pay the same immediately to the Trustee, without set-off or counterclaim or other reduction whatsoever (whether for taxes, withholding or otherwise). Each Guarantee hereunder is intended to be a general,

-15-

unsecured, senior obligation of the applicable Guarantor and will rank pari passu in right of payment with all unsecured indebtedness of such Guarantor that is not, by its terms, expressly subordinated in right of payment to the Guarantee of such Guarantor. Each Guarantor hereby agrees that, to the fullest extent permitted by applicable law, its obligations hereunder shall be full, irrevocable, unconditional and absolute, irrespective of the validity, regularity or enforceability of such Securities, the Guarantees or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder 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 such Guarantor. Such Guarantor hereby agrees that in the event of a default in payment of the principal of, or premium, if any, or interest on such Securities, or any other amounts payable under this Indenture and such Securities by the Company to the Trustee or the Holders thereof, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, legal proceedings may be instituted by the Trustee on behalf of such Holders or, subject to Section 5.7 hereof, by such Holders, on the terms and conditions set forth in this Indenture, directly against such Guarantor to enforce its Guarantee without first proceeding against the Company or any other Guarantor.

To the fullest extent permitted by applicable law, the obligations of the Guarantors under this Article Fourteen shall be as aforesaid full, irrevocable, unconditional and absolute and shall not be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Company or any Guarantor contained in any of such Securities or this Indenture, (ii) any impairment, modification, release or limitation of the liability of the Company, any Guarantor or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the decision of any court, (iii) the assertion or exercise by the Trustee or any such Holder of any rights or remedies under any of such Securities or this Indenture or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the purported assignment of any property as security for any of such Securities, including all or any part of the rights of the Company or any Guarantor under this Indenture, (v) the extension of the time for payment by the Company or any Guarantor of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of such Securities or this Indenture or of the time for performance by the Company or any Guarantor of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or any Guarantor set forth in this Indenture, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and

-16-

liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment, rehabilitation or relief of, or other similar proceeding affecting, the Company or any Guarantor or any of their respective assets, or the disaffirmance of any of such Securities, the Guarantees or this Indenture in any such proceeding, (viii) the release or discharge of the Company or any Guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (ix) the unenforceability of any of such Securities, the Guarantees or this Indenture, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Company or any Guarantor, or (xi) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, a surety or any Guarantor.

To the fullest extent permitted by applicable law, each Guarantor hereby (i) waives diligence, presentment, demand of payment, notice of acceptance, filing of claims with a court in the event of the merger, amalgamation, insolvency, winding up or bankruptcy of the Company or any Guarantor, and all demands and notices whatsoever, (ii) acknowledges that any agreement, instrument or document evidencing the Guarantees may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Guarantees without notice to them and (iii) covenants that its Guarantee will not be discharged except by complete performance of the Guarantees. To the fullest extent permitted by applicable law, each Guarantor further agrees that if at any time all or any part of any payment theretofore applied by any Person to any Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of any Guarantor, such Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Guarantees shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

The Guarantors shall be subrogated to all rights of the Holders and the Trustee against the Company in respect of any amounts paid by the Guarantors pursuant to the provisions of this Indenture; provided, however, that the Guarantors shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation with respect to any of such Securities until all of such Securities and the Guarantees thereof shall have been indefeasibly paid in full or discharged.

A director, officer, employee or shareholder, as such, of a Guarantor shall not have any liability for any obligations of such Guarantor under this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation.

-17-

To the fullest extent permitted by applicable law, no failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, power, privilege or remedy under this Article Fourteen and the Guarantees shall operate as a waiver thereof, nor shall any single or partial exercise of any rights, power, privilege or remedy preclude any other or further exercise thereof, or the exercise of any other rights, powers, privileges or remedies. The rights and remedies herein provided for are cumulative and not exclusive of any rights or remedies provided in law or equity. Nothing contained in this Article Fourteen shall limit the right of the Trustee or the Holders to take any action to accelerate the maturity of such Securities pursuant to Article Five or to pursue any rights or remedies hereunder or under applicable law.

Section 14.2. Execution and Delivery of Notation of Guarantees.

To further evidence the Guarantees, each Guarantor hereby agrees that a notation of its Guarantee may be endorsed on each Security of a series to which this Article Fourteen has been made applicable authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an officer of such Guarantor.

Each Guarantor hereby agrees that its Guarantee of Securities of a series to which this Article Fourteen has been made applicable shall remain in full force and effect notwithstanding any failure to endorse on any such Security a notation relating to any Guarantee thereof.

If an officer of a Guarantor whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, such Guarantor’s Guarantee of such Security shall be valid nevertheless.

The delivery by the Trustee of any Security of a series to which this Article Fourteen has been made applicable, after the authentication thereof under this Indenture, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the applicable Guarantor.

Section 14.3. Reports by Guarantors.

In addition to the certificates delivered to the Trustee pursuant to Section 10.7, the Guarantors shall file with the Trustee and the Commission, and transmit to Holders of Outstanding Securities of each series to which this Article Fourteen has been made applicable, such information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto; provided that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is so required to be filed with the Commission.

-18-

The receipt by the Trustee of any reports, documents or information pursuant to this Section 14.3 shall not constitute notice or constructive notice of any information contained in such reports or documents or determinable from information contained in such reports or documents.”
