(e) any invalidity of, or defect or deficiency in, the Preferred 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 5.3 that the obligations of the Guarantor hereunder shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain the consent of, the Guarantor with respect to the happening of any of the foregoing.

SECTION 5.4 Rights of Holders

(a) The Holders of a majority in liquidation amount of the Preferred Securities have the right to direct the time, method and place of conducting of any proceeding for any remedy available to the Preferred Securities Guarantee Trustee in respect of this Preferred Securities Guarantee or exercising any trust or power conferred upon the Preferred Securities Guarantee Trustee under this Preferred Securities Guarantee.

(b) If the Preferred Securities Guarantee Trustee fails to enforce this Preferred Securities Guarantee, any Holder may institute a legal proceeding directly against the Guarantor to enforce its rights under this Preferred Securities Guarantee, without first instituting a legal proceeding against the Issuer, the Preferred Securities Guarantee Trustee or any other Person.

The Guarantor shall be subrogated to all rights, if any, of the Holders against the Issuer in respect of any amounts paid to such Holders by the Guarantor under this Preferred 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 right that 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 Securities Guarantee, if, at the time of any such payment, any amounts are due and unpaid under this Preferred Securities Guarantee. If any amount shall be paid or property delivered to the Guarantor in violation of the preceding sentence, the Guarantor agrees to hold such amount or property in trust for the Holders and to pay over such amount or deliver such property to the Holders entitled thereto.

SECTION 5.7 Independent Obligations

The Guarantor acknowledges that its obligations hereunder are independent of the obligations of the Issuer with respect to the Preferred 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 Securities Guarantee notwithstanding the occurrence of any event referred to in subsections (a) through (g), inclusive, of Section 5.3 hereof.
