or waived pursuant to Section 2.6), the Guarantee Trustee shall exercise such of
the rights and powers vested in it by this Guarantee Agreement, and use the same
degree of care and skill in its exercise thereof, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

                  (d)      No provision of this Guarantee Agreement 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 all such Events of Default
         that may have occurred:

                                    (A) the duties and obligations of the
                  Guarantee Trustee shall be determined solely by the express
                  provisions of this Guarantee Agreement (including pursuant to
                  Section 2.1), and the Guarantee Trustee shall not be liable
                  except for the performance of such duties and obligations as
                  are specifically set forth in this Guarantee Agreement
                  (including pursuant to Section 2.1); 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 Agreement
                  (but in the case of any such certificates or opinions that by
                  any provision hereof or of the Trust Indenture Act are
                  specifically required to be furnished to the Guarantee
                  Trustee, the Guarantee Trustee shall be under a duty to
                  examine the same to determine whether or not they conform to
                  the requirements of this Guarantee Agreement);

                           (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 Capital Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Guarantee Trustee, or exercising any trust or power
         conferred upon the Guarantee Trustee under this Guarantee Agreement;
         and

                           (iv)     subject to Section 3.1(b), no provision of
         this Guarantee Agreement 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

                                       10

         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 Agreement or
         adequate indemnity 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 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 reasonably
         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 Agreement shall be sufficiently
         evidenced by an Officers' Certificate unless otherwise prescribed
         herein.

                           (iii)    Whenever, in the administration of this
         Guarantee Agreement, the Guarantee Trustee shall deem it desirable that
         a matter be proved or established before taking, suffering or omitting
         to take any action hereunder, the Guarantee Trustee (unless other
         evidence is herein specifically prescribed) may, in the absence of bad
         faith on its part, request and rely upon an Officers' Certificate
         which, upon receipt of such request from the Guarantee Trustee, shall
         be promptly delivered by the Guarantor.

                           (iv)     The Guarantee Trustee may consult with legal
         counsel, and the written advice or opinion of such legal counsel with
         respect to legal matters shall be full and complete authorization and
         protection in respect of any action taken, suffered or omitted to be
         taken by it hereunder in good faith and in accordance with such advice
         or opinion. Such legal counsel may be legal counsel to the Guarantor or
         any of its Affiliates and may be one of its employees. The Guarantee
         Trustee shall have the right at any time to seek instructions
         concerning the administration of this Guarantee Agreement from any
         court of competent jurisdiction.

                           (v)      The Guarantee Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by this
         Guarantee Agreement at the request or direction of any Holder unless
         such Holder shall have provided to the Guarantee Trustee such adequate
         security and indemnity as would satisfy a reasonable person in the
         position of the Guarantee Trustee against the costs, expenses
         (including attorneys' fees and expenses) and liabilities that might be
         incurred by it in complying with such request or direction, including
         such reasonable advances as may be requested by the Guarantee Trustee;
         provided that nothing contained in this Section (a)(v) shall be taken
         to relieve the Guarantee Trustee, upon the occurrence of an Event of
         Default, of its obligation to exercise the rights and powers vested in
         it by this Guarantee Agreement.

                           (vi)     The Guarantee Trustee shall not be bound to
         make any investigation into 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.

                           (vii)    The Guarantee Trustee may execute any of the
         trusts or powers hereunder or perform any duties hereunder either
         directly or by or through its agents or attorneys, and the Guarantee
         Trustee shall not be responsible for any misconduct or negligence on
         the part of any such agent or attorney appointed by it with due care
         hereunder.

                           (viii)   Whenever in the administration of this
         Guarantee Agreement 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, (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 acting in
         accordance with such instructions.

                  (b)      No provision of this Guarantee Agreement 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 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 to act in accordance with such
power and authority.

         SECTION 3.3.  COMPENSATION; INDEMNITY; FEES.

                  The Guarantor agrees:

                  (a)      to pay to the Guarantee Trustee from time to time
such reasonable compensation for all services rendered by it hereunder as may be
agreed by the Guarantor and the Guarantee Trustee from time to time (which
compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust);

                  (b)      except as otherwise expressly provided herein, to
reimburse the Guarantee Trustee upon request for all reasonable expenses,
disbursements and advances incurred or made by the Guarantee Trustee in
accordance with any provision of this Guarantee Agreement (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be
attributable to its negligence or bad faith; and

                  (c)      to indemnify the Guarantee Trustee, any Affiliate of
the Guarantee Trustee and any officer, director, shareholder, employee,
representative or agent of the Guarantee Trustee (each, an "Indemnified Person")
for, and to hold each Indemnified Person harmless against, any loss, liability
or expense incurred without negligence, willful misconduct or bad faith on the
part of the Indemnified Person, arising out of or in connection with the
acceptance or administration of this Guarantee Agreement, including the costs
and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder.

                  The Guarantee Trustee will not claim or exact any lien or
charge on any Guarantee Payments as a result of any amount due to it under this
Guarantee Agreement.

                  The provisions of this Section 3.3 shall survive the
termination of this Guarantee Agreement or the resignation or removal of the
Guarantee Trustee.

                                GUARANTEE TRUSTEE

         SECTION 4.1.  GUARANTEE TRUSTEE; ELIGIBILITY.

                  (a)      There shall at all times be a Guarantee Trustee
which shall:

                           (i)      not be an Affiliate of the Guarantor; and

                           (ii)     be a Person that is eligible pursuant to the
         Trust Indenture Act to act as such and has a combined capital and
         surplus of at least $50,000,000, and shall be a corporation meeting the
         requirements of Section 310(a) of the Trust Indenture Act. If such
         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of its supervising or examining
         authority, then, for the purposes of this Section 4.1 and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

                  (b)      If at any time the Guarantee Trustee shall cease to
be eligible to so act under Section 4.1(a), the Guarantee Trustee shall
immediately resign in the manner and with the effect set out in Section 4.2.

                  (c)      If the Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply
with the provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 4.2.  APPOINTMENT, REMOVAL AND RESIGNATION OF THE GUARANTEE
TRUSTEE.

                  (a)      Subject to Section 4.2(c), the Guarantee Trustee may
be appointed or removed at any time by the action of the Holders of a Majority
in Liquidation Amount of the Capital Securities delivered to the Guarantee
Trustee and the Guarantor (i) for cause or (ii) if a Debenture Event of Default
(as defined in the Trust Agreement) shall have occurred and be continuing at any
time.

                  (b)      Subject to Section 4.2(c), the Guarantee Trustee may
resign from office (without need for prior or subsequent accounting) by giving
written notice thereof to the Holders and the Guarantor and by appointing a
successor Guarantee Trustee. The Guarantee Trustee shall appoint a successor by
requesting from at least three Persons meeting the requirements of Section
4.1(a) their expenses and charges to serve as the Guarantee Trustee, and
selecting the Person who agrees to the lowest expenses and charges.

                  (c)      The Guarantee Trustee appointed hereunder shall hold
office until a Successor Guarantee Trustee shall have been appointed and shall
have accepted such appointment. No removal or resignation of a Guarantee Trustee
shall be effective until a Successor Guarantee Trustee has been appointed and
has accepted such appointment by written instrument executed by such Successor
Guarantee Trustee and delivered to the Guarantor and, in the case of any
resignation, the resigning Guarantee Trustee.

                  (d)      If no Successor Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery to the Holders and the Guarantor of a notice of resignation,
the resigning Guarantee Trustee may petition, at the expense of the Guarantor,
any court of competent jurisdiction for appointment of a Successor Guarantee
Trustee. Such court may thereupon, after prescribing such notice, if any, as it
may deem proper, appoint a Successor Guarantee Trustee.

                  (e)      If a resigning Guarantee Trustee shall fail to
appoint a successor, or if a Guarantee Trustee shall be removed or become
incapable of acting as Guarantee Trustee and a replacement shall not be
appointed prior to such resignation or removal, or if a vacancy shall occur in
the office of Guarantee Trustee for any cause, the Holders of the Capital
Securities, by

                                       15
<PAGE>

the action of the Holders of record of not less than 25% in aggregate
Liquidation Amount (as defined in the Trust Agreement) of the Capital Securities
then Outstanding (as defined in the Trust Agreement) delivered to such Guarantee
Trustee, may appoint a Successor Guarantee Trustee or Trustees. If no successor
Guarantee Trustee shall have been so appointed by the Holders of the Capital
Securities and accepted appointment, any Holder, on behalf of such Holder and
all others similarly situated, or any other Guarantee Trustee, may petition any
court of competent jurisdiction for the appointment of a successor Guarantee
Trustee.

                                    GUARANTEE

         SECTION 5.1.  GUARANTEE.

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

         SECTION 5.2.  WAIVER OF NOTICE AND DEMAND.

                  The Guarantor hereby waives notice of acceptance of this
Guarantee Agreement and of any liability to which it applies or may apply,
presentment, demand for payment, any right to require a proceeding first against
the Guarantee Trustee, the Issuer Trust 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 Agreement shall in no way be affected or impaired
by reason of the happening from time to time of any of the following:

                                       16
<PAGE>

                  (a)      the release or waiver, by operation of law or
otherwise, of the performance or observance by the Issuer Trust of any express
or implied agreement, covenant, term or condition relating to the Capital
Securities to be performed or observed by the Issuer Trust;

                  (b)      the extension of time for the payment by the Issuer
Trust of any portion of the Distributions (other than an extension of time for
payment of Distributions that results from the extension of any interest payment
period on the Debentures as provided in the Indenture), Redemption Price,
Liquidation Distribution or any other sums payable under the terms of the
Capital Securities or the extension of time for the performance of any other
obligation under, arising out of, or in connection with, the Capital Securities;

                  (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 Capital
Securities, or any action on the part of the Issuer Trust granting indulgence or
extension of any kind;

                  (d)      the voluntary or involuntary liquidation,
dissolution, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer Trust or any of the assets of
the Issuer Trust;

                  (e)      any invalidity of, or defect or deficiency in, the
Capital 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
(other than payment of the underlying obligation), 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.

Agreement will be deposited with the Guarantee Trustee to be held for the
benefit of the Holders; (ii) the Guarantee Trustee has the right to enforce this
Guarantee Agreement on behalf of the Holders; (iii) the Holders of a Majority in
Liquidation Amount of the Capital Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of this Guarantee Agreement or exercising any trust
or power conferred upon the Guarantee Trustee under this Guarantee Agreement;
and (iv) any Holder may institute a legal proceeding directly against the
Guarantor to enforce its rights under this Guarantee Agreement without first
instituting a legal proceeding against the Guarantee Trustee, the Issuer Trust
or any other Person.

         SECTION 5.5.  GUARANTEE OF PAYMENT.

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

         SECTION 5.6.  SUBROGATION.

                  The Guarantor shall be subrogated to all rights (if any) of
the Holders against the Issuer Trust in respect of any amounts paid to the
Holders by the Guarantor under this Guarantee Agreement; 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 Guarantee Agreement, if, at the time of
any such payment, any amounts are due and unpaid under this Guarantee Agreement.
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 5.7.  INDEPENDENT OBLIGATIONS.

                  The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer Trust with respect to the Capital
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.

                                   ARTICLE VI

         SECTION 6.1.  SUBORDINATION.

                  The obligations of the Guarantor under this Guarantee
Agreement will constitute unsecured obligations of the Guarantor and will rank
subordinate and junior in right of payment to all Senior Debt (as defined in the
Indenture) of the Guarantor to the extent and in the manner set forth in the
Indenture with respect to the Debentures, and the provisions of Article Eighteen
of the Indenture will apply, mutatis mutandis, to the obligations of the
Guarantor hereunder. The obligations of the Guarantor hereunder do not
constitute Senior Debt (as defined in the Indenture) of the Guarantor.

         SECTION 6.2.  PARI PASSU GUARANTEES.

                  The obligations of the Guarantor under this Guarantee
Agreement shall rank pari passu with the obligations of the Guarantor under (i)
any similar guarantee agreements issued by the Guarantor on behalf of the
holders of preferred or capital securities issued by any statutory trust, (ii)
the Indenture and the Debt Securities (as defined therein) issued thereunder;
(iii) any expense agreements entered into by the Guarantor in connection with
the offering of preferred or capital securities by any statutory trust, and (iv)
any other security, guarantee or other agreement or obligation that is expressly
stated to rank pari passu with the obligations of the Guarantor under this
Guarantee Agreement or with any obligation that ranks pari passu with the
obligations of the Guarantor under this Guarantee Agreement.
