The obligation of the Guarantor to make the Guarantee Payments under this Preferred Trust Securities 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 Preferred Trust 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 Preferred Trust Securities or the extension of time for the performance of any other obligation under, arising out of, or in connection with, the Preferred Trust Securities (other than pursuant to the terms of the Trust Agreement); (c) any failure, omission, delay or lack of diligence on the part of the Property Trustee or the Holders to enforce, assert or exercise any right, privilege, power or remedy conferred on the Property Trustee or the Holders pursuant to the terms of the Preferred Trust Securities, or any action on the part of the Issuer granting indulgence or 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 Preferred Trust Securities; (f) the settlement or compromise of any obligation guaranteed hereby or hereby incurred; or (g) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a guarantor, it being the intent of this Section 5.03 that the obligations of the Guarantor hereunder shall be absolute and unconditional under any and all circumstances. There shall be no obligation of the Trust Guarantee Trustee, the Property 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 Trust Securities Guarantee will be deposited with the Trust Guarantee Trustee to be held for the benefit of the Holders; (ii) if an Event of Default or a Trust Enforcement Event has occurred and is continuing, the Trust Guarantee Trustee has the right to enforce this Preferred Trust Securities Guarantee on behalf of the Holders; (iii) the Holders of a Majority in Liquidation Amount of the Preferred Trust Securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trust Guarantee Trustee in respect of this Preferred Trust Securities Guarantee or exercising any trust or power conferred upon the 12 Trust Guarantee Trustee under this Preferred Trust Securities Guarantee; and (iv) if the Trust Guarantee Trustee fails to enforce its rights under this Preferred Trust Securities Guarantee after a Holder has made a written request therefor, such Holder may institute a legal proceeding directly against the Guarantor to enforce the Trust Guarantee Trustee's rights under this Preferred Trust Securities Guarantee without first instituting a legal proceeding against the Issuer, the Trust Guarantee Trustee or any other Person. Notwithstanding the foregoing, if the Guarantor has failed to make a Guarantee Payment when due, a Holder may directly institute a proceeding in that Holder's own name against the Guarantor for enforcement of this Preferred Trust Securities Guarantee for payment. The Guarantor waives any right or remedy to require that any action be brought first against the Issuer, the Trust Guarantee Trustee or any other Person before proceeding directly against the Guarantor. SECTION 5.05 GUARANTEE OF PAYMENT. This Preferred Trust 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 Trust 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 Trust Securities Guarantee, if, at the time of any such payment, any amounts of Guarantee Payments are due and unpaid under this Preferred Trust 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 Trust 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 Trust 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 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 Trust 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 no such Additional Amounts shall be payable: 13 (A) to, or to a Person on behalf of, a Holder who is liable for Gross-Up Taxes with respect to the Preferred Trust Securities Guarantee, by reason of such Holder having some connection with a 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 unless, in the case of the United Kingdom, that connection arises solely as a result of the Control Party being a resident of the United Kingdom; (B) to, or to a Person on behalf of, a Holder who presents a Preferred Trust 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 Trust 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 Trust 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. Such Additional Amounts will also not be payable where, had the beneficial owner of the Preferred Trust Security (or any interest therein) been the Holder of the Preferred Trust 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; COVENANTS SECTION 6.01 LIMITATION OF TRANSACTIONS. So long as any Preferred Trust Securities remain outstanding, if (A) for any quarterly period, the Issuer does not pay to the holders of the outstanding Preferred Trust Securities an amount equal to the Distributions in respect of Preferred Entitlements on any Preferred Partnership Securities; (B) an Investment Event of Default with respect to any Affiliate Investment Instruments has occurred and is continuing and the Guarantor defaults on its obligations under the related Investment Guarantee; or (C) the Guarantor is in continuing default of its obligations under this Preferred Trust Securities Guarantee or the Partnership Guarantee, then, during such period neither the Guarantor nor any Investment Affiliate that has issued Affiliate Investment Instruments shall, directly or indirectly, 14 (i) declare or pay any cash dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of its issued share capital or comparable equity interest other than dividends or distributions paid to the Guarantor or any of the Guarantor's subsidiaries; (ii) make any payments on, or repay, repurchase or redeem, any of its debt securities that rank equally with or junior to any Affiliate Investment Instruments or any Investment Guarantee; (iii) make any payments with respect to any guarantee that ranks equally or junior to any of the Affiliate Investment Instruments or any Investment Guarantee; (iv) make any payments on, or repay, repurchase or redeem, any debt or other securities held or issued by, or make any payments with respect to any guarantee of such debt or other securities, or make any loans or advances to, any Affiliate of the Guarantor that is not also a subsidiary of the Guarantor; or (v) permit their respective subsidiaries to make any payments on, or repay, repurchase or redeem, any debt or other securities held or issued by, or make any payments with respect to any guarantee of such debt or other securities, or make any loans or advances to, any Affiliate of the Guarantor that is not also a subsidiary of the Guarantor, in each case other than: (a) any payments required by law; (b) dividends or distributions in, or options, warrants or rights to subscribe for or purchase, shares or comparable equity interests of the Guarantor or of such Investment Affiliate, and exchanges or conversions of shares or comparable equity interests of one class for shares or comparable equity interests of another class of the same issuer; (c) payments by the Guarantor under this Preferred Trust Securities Guarantee or the Partnership Guarantee; (d) payments by such Investment Affiliate on its Affiliate Investment Instruments or payments by the Guarantor under the Investment Guarantee related to such Affiliate Investment Instruments; (e) any dividend or payment by the Guarantor which is applied, directly or indirectly, to any Tax Payments; or (f) payments by the Guarantor or such Investment Affiliate, directly or indirectly, on loans from Funding (or any subsidiary of the Guarantor) to the Guarantor or any of the Guarantor's subsidiaries made with the proceeds from the issuance by Funding (or such other subsidiary making such loan) of securities guaranteed by the Guarantor (provided that such guarantee ranks senior to all subordinated indebtedness of the Guarantor, including the Investment Guarantees), or loans made in connection with the reinvestment of those proceeds. 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 Trust Guarantee Trustee an instrument in substantially the form of Exhibit A hereto. 15 SECTION 6.02 SUBORDINATION. This Preferred Trust Securities Guarantee will constitute an unsecured obligation of the Guarantor and will rank (i) subordinate and junior in right of payment to all other liabilities of the Guarantor, including the Investment Guarantees, except those that are made to rank equally or subordinate by their terms to this Preferred Trust Securities Guarantee, (ii) equally with any preference share capital now or hereafter issued by the Guarantor and with any guarantee now or hereafter entered into by the Guarantor in respect of any preferred security of any Finance Subsidiary, and (iii) senior to all common stock of the Guarantor. Nothing in this Section 6.02 shall apply to claims of, or payments to, the Trust Guarantee Trustee under or pursuant to Section 4.02 hereof. SECTION 6.03 COVENANTS. For so long as the Preferred Trust Securities remain outstanding, the Guarantor covenants (a) to cause a direct or indirect wholly-owned United States subsidiary of the Guarantor to retain the Control Certificate, (b) to cause the Trust to remain a statutory business trust and not to voluntarily dissolve, wind-up, liquidate or be terminated, except as permitted by the Trust Agreement and (c) to use its commercially reasonable efforts to ensure that the Trust will not be (i) an Investment Company for purposes of the 1940 Act or (ii) classified as other than a grantor trust for United States federal income tax purposes or as other than a transparent entity for United Kingdom taxation purposes. ARTICLE VII TERMINATION SECTION 7.01 TERMINATION. Subject to Section 4.02 hereof, this Preferred Trust Securities Guarantee shall terminate and be of no further force and effect upon: (i) full payment of the Redemption Price of all Preferred Trust Securities, (ii) the distribution of Preferred Partnership Securities to Holders in exchange for all of the Preferred Trust Securities, or (iii) full payment of the amounts payable in accordance with the Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing, this Preferred Trust Securities Guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any Holder must restore payment of any sums paid with respect to Preferred Trust Securities or under this Preferred Trust Securities Guarantee.

The Guarantor may consolidate with, or sell, lease or convey all or substantially all of its assets to, or merge with or into any other corporation or other entity; provided, that in any such case, (i) either the Guarantor shall be the continuing entity, or the successor entity shall be a corporation or other entity organized and existing under the laws of England and Wales, or any state of the United States of America, and such successor entity shall expressly assume the due and punctual payment of the Guarantee Payments payable pursuant to Section 5.01 hereof and the due and punctual performance and observance of all of the covenants and conditions of this Preferred Trust Securities Guarantee to be performed by the Guarantor by a separate guarantee satisfactory to the Trust Guarantee Trustee, executed and delivered to the Trust Guarantee Trustee by such entity, and (ii) the guarantor or such successor entity, as the case may be, shall not, immediately after such merger or consolidation, or such sale, lease or conveyance, be in default in the performance of any such covenant or condition.

The Guarantor irrevocably consents ----------------------- to the nonexclusive jurisdiction of any court of the State of New York or any United States Federal court sitting, in each case, in the Borough of Manhattan, The City of New York, New York, United States of America, and any appellate court from any thereof in any suit, action or proceeding that may be brought in connection with this Preferred Trust Securities Guarantee, and waives any immunity from the jurisdiction of such courts. The Guarantor irrevocably waives, to the fullest extent permitted by law, any objection to any such suit, action or proceeding that may be brought in such courts whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or proceeding has been brought in an inconvenient forum. The Guarantor agrees, to the fullest extent that it lawfully may do so, that final judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding upon the Guarantor, and waives, to the fullest extent permitted by law, any objection to the enforcement by any competent court in the Jurisdiction of Incorporation of judgments validly obtained in any such court in New York on the basis of such suit, action or proceeding; provided, however, that the Guarantor does not waive, and the foregoing provisions of this sentence shall not constitute or be deemed to constitute a waiver of, (i) any right to appeal any such judgment, to seek any stay or otherwise to seek reconsideration or review of any such judgment, (ii) any stay of execution or levy pending an appeal from, or a suit, action or proceeding for reconsideration of, any such judgment, or (iii) any other right or remedy of the Guarantor to the extent not expressly waived in accordance with this Section.

The Trust Guarantee Trustee shall not be obligated and shall have no responsibility with respect to any failure by the Guarantor to take any such action.

(d) Waiver of Immunities. To the extent that the Guarantor or -------------------- any of its respective properties, assets or revenues may have or may hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty or otherwise, from legal action, suit or proceeding, from the giving of any relief in any thereof, from set-off or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Preferred Trust Securities Guarantee, the Guarantor hereby irrevocably and unconditionally waives and agrees not to plead or claim, any such immunity and consents to such relief and enforcement.
