In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.6), the Guarantee Trustee shall exercise the rights and powers vested in it by this Guarantee, and use the same degree of care and skill in its exercise thereof, as a prudent individual would exercise or use under the circumstances in the conduct of his or her own affairs. (d) No provision of this Guarantee shall be construed to relieve the Guarantee Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) prior to the occurrence of any Event of Default and after the curing or waiving of such Events of Default that may have occurred: (A) the duties and obligations of the Guarantee Trustee shall be determined solely by reference to the express provisions of this Guarantee, and the Guarantee Trustee shall not be liable except for the performance of those duties and obligations specifically set forth in this Guarantee, and no implied covenants or obligations shall be read into this Guarantee against the Guarantee Trustee; and (B) in the absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Guarantee Trustee and conforming to the requirements of this Guarantee; but in the case of any such certificates or opinions that are specifically required to be furnished to the Guarantee Trustee under this Guarantee, the Guarantee Trustee shall be under a duty to examine such certificates or opinions to determine whether or not they conform to the requirements of this Guarantee; (ii) the Guarantee Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Guarantee Trustee, unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent facts upon which such judgment was made; (iii) the Guarantee Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a Majority in Liquidation Amount of the Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee in respect of this 6 Guarantee, or the exercise of any trust or power conferred upon the Guarantee Trustee under this Guarantee; and (iv) no provision of this Guarantee shall require the Guarantee Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if the Guarantee Trustee shall have reasonable grounds for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Guarantee or indemnity, reasonably satisfactory to the Guarantee Trustee, against such risk or liability is not reasonably assured to it. SECTION 3.2. Certain Rights of Guarantee Trustee. (a) Subject to the provisions of Section 3.1: (i) The Guarantee Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. (ii) Any direction or act of the Guarantor contemplated by this Guarantee shall be sufficiently evidenced by a Direction or an Officers' Certificate. (iii) Whenever, in the administration of this Guarantee, the Guarantee Trustee shall deem it desirable that a matter be proved or established before taking, suffering or omitting any action hereunder, the Guarantee Trustee (unless other evidence is specifically prescribed in this Guarantee) may request, in the absence of bad faith on its part, and conclusively rely upon an Officers' Certificate which, upon receipt of such request, shall be promptly delivered by the Guarantor.

(v) The Guarantee Trustee may consult with counsel of its choice or other experts. The advice or opinion of such counsel and experts with respect to legal matters or advice within the scope of such experts' area of expertise, and the written advice or opinion of such counsel with respect to such matters, shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by the Guarantee Trustee under this Guarantee in good faith and in accordance with such advice or opinion. Such counsel may be counsel to the Guarantor or any of its Affiliates and may include any of its employees. The Guarantee Trustee shall have the right at any time to seek instructions concerning the administration of this Guarantee from any court of competent jurisdiction.

The foregoing will not relieve the Guarantee Trustee, upon the occurrence of an Event of Default under this Guarantee, of its obligation to exercise the rights and powers vested in it by this Guarantee. (vii) The Guarantee Trustee shall not be bound to investigate the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Guarantee Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit.

(ix) Any action taken by the Guarantee Trustee or its agents under this Guarantee shall bind the Holders of the Securities, and the signature of the Guarantee Trustee or its agents alone shall be sufficient and effective to perform any such action. No third party shall be required to investigate the authority of the Guarantee Trustee so to act or the Guarantee Trustee's compliance with any of the terms and provisions of this Guarantee, both of which shall be evidenced conclusively by the Guarantee Trustee's or its agent's taking such action. (x) Whenever in the administration of this Guarantee, the Guarantee Trustee shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder, the Guarantee Trustee (A) may request instructions from the Holders of a Majority in Liquidation Amount of the Securities, (B) may refrain from enforcing such remedy or right or taking such other action until such instructions are received and (C) shall be protected in conclusively relying on or acting in accordance with such instructions. (b) No provision of this Guarantee shall be deemed to impose any duty or obligation on the Guarantee Trustee to perform any act or acts or exercise any right, power, duty or obligation conferred or imposed on it, in any jurisdiction in which it shall be illegal, or in which the Guarantee Trustee shall be unqualified or incompetent to act in accordance with applicable law, to perform any such act or acts, or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Guarantee Trustee shall be construed to be a duty. SECTION 3.3. Not Responsible for Recitals or Issuance of Guarantee. The recitals contained in this Guarantee shall be taken as the statements of the Guarantor, and the Guarantee Trustee does not assume any responsibility for their correctness. The Guarantee Trustee makes no representation as to the validity or sufficiency of this Guarantee. 8 ARTICLE IV GUARANTEE TRUSTEE SECTION 4.1. Guarantee Trustee; Eligibility.

The Guarantee Trustee may resign from office (without need for prior or subsequent accounting) by a written instrument executed by the Guarantee Trustee and delivered to the Guarantor, which resignation shall not take effect until a Successor Guarantee Trustee has been appointed and has accepted such appointment by a written instrument executed by such Successor Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee Trustee. (d) If no Successor Guarantee Trustee shall have been appointed and shall have accepted appointment as provided in this Section 4.2 within 60 days after delivery to the Guarantor of an instrument of resignation, the resigning Guarantee Trustee may petition any court of competent jurisdiction for 9 appointment of a Successor Guarantee Trustee.

The Guarantor's obligation to make a Guarantee Payment may be satisfied by direct payment of the required amounts by the Guarantor to the Holders of the Securities or by causing the Issuer to pay such amounts to the Holders of the Securities. If a Trust Enforcement Event has occurred and is continuing, the rights of the Holders of the Common Securities to receive Guarantee Payments will be subordinated to the rights of the Holders of Preferred Securities to receive Guarantee Payments. SECTION 5.2. Waiver of Notice and Demand. The Guarantor hereby waives notice of acceptance of this Guarantee and of any liability to which this Guarantee applies or may apply, presentment, demand for payment, any right to require a proceeding first against the Issuer or any other Person before proceeding against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice of redemption and all other notices and demands. SECTION 5.3. Obligations Not Affected. The obligations, covenants, agreements and duties of the Guarantor under this Guarantee shall in no way be affected or impaired by reason of the happening from time to time of any of the following: (a) the release or waiver, by operation of law or otherwise, of the performance or observance by the Issuer of any express or implied agreement, covenant, term or condition relating to the Securities to be performed or observed by the Issuer; (b) the extension of time for the payment by the Issuer of all or any portion of the Distributions, redemption price, Liquidation Distribution or any other sums payable under the terms of the Securities or the extension of time for the performance of any other obligation under, arising out of, or in connection with, the Securities; 10 (c) any failure, omission, delay or lack of diligence on the part of the Holders of the Securities to enforce, assert or exercise any right, privilege, power or remedy conferred on the Holders of the Securities pursuant to the terms of the Securities, or any action on the part of the Issuer granting indulgence or an extension of any kind; (d) the voluntary or involuntary liquidation, dissolution, sale of any collateral, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of debt of, or other similar proceedings affecting, the Issuer or any of the assets of the Issuer; (e) any invalidity of, or defect or deficiency in, the Securities; (f) the settlement or compromise of any obligation guaranteed or incurred in this Guarantee; or (g) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of the Guarantor, it being the intent of this Section 5.3 that the obligations of the Guarantor under this Guarantee shall be absolute and unconditional under any and all circumstances. There shall be no obligation of the Holders of the Securities to give notice to, or obtain consent of, the Guarantor with respect to the happening of any of the foregoing. SECTION 5.4. Rights of Holders.

If any amount shall be paid to 11 the Guarantor in violation of the preceding sentence, the Guarantor agrees to hold such amount in trust for the Holders of the Securities and to pay over such amount to such Holders. SECTION 5.7. Independent Obligations. The Guarantor acknowledges that its obligations hereunder are independent of the obligations of the Issuer with respect to the Securities, and that the Guarantor shall be liable as principal and as debtor under this Guarantee to make Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the occurrence of any event referred to in subsections (a) through (g) of Section 5.3 hereof.
