                           to the Preferred Securities Guarantee Trustee and
                           conforming to the requirements of this Preferred
                           Securities Guarantee; but in the case of any such
                           certificates or opinions that by any provision hereof
                           are specifically required to be furnished to the

                  a Responsible Officer of the Preferred Securities Guarantee
                  Trustee, unless it shall be proved that the Preferred
                  Securities Guarantee Trustee was negligent in ascertaining the
                  pertinent facts;

                           (iii) the Preferred Securities 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 Preferred Securities relating to the

                           (iv) no provision of this Preferred Securities
                  Guarantee shall require the Preferred Securities 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 Preferred Securities 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 Preferred Securities Guarantee or if indemnity
                  reasonably satisfactory to the Preferred Securities Guarantee
                  Trustee against such risk or liability is not reasonably

                  The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert. The

                  In addition, the Guarantor irrevocably and unconditionally
agrees to cause the Issuer to deliver to the Holders such securities and other
property as may be deliverable to them in accordance with the terms of the

redemption, liquidation or other provision of the Debentures, [the Other
Documents] or the Preferred Securities.

SECTION 5.2       Waiver of Notice and Demand

                  The Guarantor hereby waives notice of acceptance of this
Preferred Securities Guarantee and of any liability to which it 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 Preferred 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 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 any sums payable or the performance by the Issuer of any other
obligation under, arising out of, or in

                                       13

<PAGE>

connection with, the Preferred Securities (other than an extension of time
permitted by the Indenture);

                  (c) any failure, omission, delay or lack of diligence on the
part of the Holders to enforce, assert or exercise any right, privilege, power
or remedy conferred on the Holders pursuant to the terms of the Preferred
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 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. Notwithstanding the foregoing, if the Guarantor has failed to make a
Guarantee Payment or to perform any of its other obligations under Section 5.1,
a Holder may directly institute a proceeding in the Holder's own name against
the Guarantor for enforcement of this Preferred Securities Guarantee for the
portion of such Guarantee Payment or the performance of such other obligation to
which such Holder is entitled. The Guarantor waives any right or remedy to
require that any action on this Preferred Securities Guarantee be brought first
against the Issuer or any other person or entity before proceeding directly
against the Guarantor.

duplication of amounts theretofore paid by the Issuer) or upon distribution of
Debentures to Holders as provided in the Agreement.

SECTION 5.6       Subrogation

                  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.
