There shall be no obligation of the Partnership Guarantee Trustee or the Holders to give notice to, or obtain consent of, the Guarantor or any other Person with respect to the happening of any of the foregoing. SECTION 5.04 RIGHTS OF HOLDERS. The Guarantor expressly acknowledges that: (i) this Preferred Partnership Securities Guarantee will be deposited with the Partnership Guarantee Trustee to be held for the benefit of the Holders; (ii)in the event of the appointment of a Special Representative to, among other things, enforce this Preferred Partnership Securities Guarantee, the Special Representative may take possession of this Preferred Partnership Securities Guarantee for such purposes, (iii) if no Special Representative has been appointed, the Partnership Guarantee Trustee has the right to enforce this Preferred Partnership Securities Guarantee on behalf of the Holders; (iii) the Holders of a Majority in Liquidation Preference of the Preferred Partnership Securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Partnership Guarantee Trustee or the Special Representative in respect of this Preferred Partnership Securities Guarantee or exercising any trust or power conferred under this Preferred Partnership Securities Guarantee; and (iv) if either the Partnership Guarantee Trustee or the Special Representative fails to enforce its rights under this Preferred Partnership Securities Guarantee after a Holder has made a written request therefor, such Holder may institute a legal proceeding directly against the Guarantor to enforce its rights under this Preferred Partnership Securities Guarantee without first instituting a legal proceeding against the Issuer, the Special Representative, the Partnership Guarantee Trustee, or any other Person. Notwithstanding the foregoing, if the Guarantor has failed to make a Guarantee Payment, a Holder may directly institute a proceeding in that Holder's own name against the Guarantor for enforcement of this Preferred Partnership Securities Guarantee for payment. 13 If a Special Representative has been appointed, this Special Representative may enforce the rights of the Holders under this Preferred Partnership Securities Guarantee. SECTION 5.05 GUARANTEE OF PAYMENT. This Preferred Partnership Securities Guarantee creates a guarantee of payment and not of collection. This Guarantee Agreement will not be discharged except by payment of the Guarantee Payments in full (without duplication). SECTION 5.06 SUBROGATION. The Guarantor shall be subrogated to all, if any, rights of the Holders against the Issuer in respect of any amounts paid to the Holders by the Guarantor under this Preferred Partnership Securities Guarantee; provided, however, that the Guarantor shall not (except to the extent required by mandatory provisions of law) be entitled to enforce or exercise any rights which it may acquire by way of subrogation or any indemnity, reimbursement or other agreement, in all cases as a result of payment under this Preferred Partnership Securities Guarantee, if, at the time of any such payment, any amounts of Guarantee Payments are due and unpaid under this Preferred Partnership Securities Guarantee. If any amount shall be paid to the Guarantor in violation of the preceding sentence, the Guarantor agrees to hold such amount in trust for the Holders and to pay over such amount to the Holders. SECTION 5.07 INDEPENDENT OBLIGATIONS. The Guarantor acknowledges that its obligations hereunder are independent of the obligations of the Issuer with respect to the Preferred Partnership Securities and that the Guarantor shall be liable as principal and as debtor hereunder to make Guarantee Payments pursuant to the terms of this Preferred Partnership Securities Guarantee notwithstanding the occurrence of any event referred to in subsections (a) through (g), inclusive, of Section 5.03. SECTION 5.08 ADDITIONAL AMOUNTS. All Guarantee Payments shall be made free and clear of, and without withholding or deduction for or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature imposed levied, collected, withheld or assessed by a jurisdiction in which the Guarantor is incorporated or organized or is managed or controlled or has a place of business or any political subdivision or taxing authority thereof (each, a "Taxing Jurisdiction"), unless such withholding or deduction is required by law. In the event of any such withholding or deduction ("Gross-Up Taxes"), the Guarantor shall pay to each Holder of the Preferred Partnership Securities such additional amounts ("Additional Amounts") as shall be necessary so that the net amount received by such Holder after withholding or deduction shall equal the amount that would otherwise have been due to such Holder in the absence of such withholding or deduction, except that, if the Preferred Partnership Securities are distributed to the holders of the Preferred Trust Securities in liquidation of the Trust, no such Additional Amounts shall be payable: (A) to, or to a Person on behalf of, a Holder who is liable for Gross-Up Taxes with respect to the Preferred Partnership Securities Guarantee, by reason of such Holder having some connection with the relevant Taxing Jurisdiction (including being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Taxing Jurisdiction) other than through the mere receipt of Guarantee Payments; 14 (B) to, or to a Person on behalf of, a Holder who presents a Preferred Partnership Security (whenever presentation is required) for payment more than 30 days after the date on which payment first becomes due except to the extent that such Holder would have been entitled to such Additional Amounts on presenting such Preferred Partnership Security for payment on the last day of such period of 30 days; (C) to, or to a Person on behalf of, a Holder who presents a Preferred Partnership Security (when presentation is required) other than in The City of New York; or (D) to, or to a Person on behalf of, a Holder who would not be liable or subject to Gross-Up Taxes by making a declaration of non-residence or similar claim for exemption to the relevant tax authority. Following any distribution of Preferred Partnership Securities to the holders of the Preferred Trust Securities upon liquidation of the Trust, no Additional Amounts will be payable where, had the beneficial owner of the Preferred Partnership Security (or any interest therein) been the Holder of the Preferred Partnership Security, it would not have been entitled to payment of Additional Amounts by reason of any one or more of clauses (A) through (D) above. If the Guarantor shall determine that Additional Amounts will not be payable because of the immediately preceding sentence, the Guarantor will inform such Holder promptly after making such determination setting forth the reason(s) thereof. ARTICLE VI LIMITATION OF TRANSACTIONS; SUBORDINATION SECTION 6.01 LIMITATION OF TRANSACTIONS.

In connection with the obligations set forth in this Section 6.01, the Guarantor agrees to cause each Investment Affiliate that has issued Affiliate Investment Instruments to execute and deliver to the Partnership Guarantee Trustee an instrument in substantially the form of Exhibit A hereto. 16 SECTION 6.02 SUBORDINATION.
