     The Holders of a Majority in Liquidation Amount of Trust Preferred
Securities may, by vote, on behalf of the Holders of all of the Trust Preferred
Securities, waive any past Event of Default and its consequences. Upon such
waiver, any such Event of Default shall cease to exist, and any Event of Default

Guarantee Trustee, unless such defaults have been cured before the giving of
such notice; provided, that, except in the case of a default by Guarantor on any
of its payment obligations, the Trust Preferred Guarantee Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of the directors and/or Responsible
Officers of the Trust Preferred Guarantee Trustee in good faith determines that

the Trust Preferred Guarantee Trustee charged with the administration of the
Trust Agreement shall have obtained actual knowledge of such Event of Default.

     SECTION 2.8    CONFLICTING INTERESTS.

         POWERS, DUTIES AND RIGHTS OF TRUST PREFERRED GUARANTEE TRUSTEE

     SECTION 3.1    POWERS AND DUTIES OF THE TRUST PREFERRED GUARANTEE TRUSTEE.

             (a)    This Trust Preferred Securities Guarantee shall be held by
     the Trust Preferred Guarantee Trustee for the benefit of the Holders of the
     Trust Preferred Securities, and the Trust Preferred Guarantee Trustee shall
     not transfer this Trust Preferred Securities Guarantee to any Person except
     a Holder of Trust Preferred Securities exercising his or her rights
     pursuant to Section 5.4(b) hereof or to a Successor Trust Preferred
     Guarantee Trustee on acceptance by such Successor Trust Preferred Guarantee
     Trustee of its appointment to act as Successor Trust Preferred Guarantee
     Trustee. The right, title and interest of the Trust Preferred Guarantee
     Trustee shall automatically vest in any Successor Trust Preferred Guarantee
     Trustee, and such vesting and cessation of title shall be effective whether
     or not conveyancing documents have been executed and delivered pursuant to
     the appointment of such Successor Trust Preferred Guarantee Trustee.

             (b)    If an Event of Default actually known to a Responsible
     Officer of the Trust Preferred Guarantee Trustee has occurred and is
     continuing, the Trust Preferred Guarantee Trustee shall enforce this Trust
     Preferred Securities Guarantee for the benefit of the Holders of the Trust
     Preferred Securities.

             (c)    The Trust Preferred Guarantee Trustee, before the occurrence
     of any Event of Default and after the curing of all Events of Default that
     may have occurred, shall undertake to perform only such duties as are
     specifically set forth in this Trust Preferred Securities Guarantee. In
     case an Event of Default has occurred (that has not been cured or waived
     pursuant to Section 2.6 hereof) and is actually known to a Responsible
     Officer of the Trust Preferred Guarantee Trustee, the Trust Preferred
     Guarantee Trustee shall exercise such of the rights and powers vested in it
     by this Trust Preferred Securities Guarantee, 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. No
     implied covenants shall be read into the Trust Preferred Securities
     Guarantee against the Trust Preferred Guarantee Trustee.

                                       -7-



             (d)    No provision of this Trust Preferred Securities Guarantee
     shall be construed to relieve the Trust Preferred 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 Trust Preferred
                         Guarantee Trustee shall be determined solely by the
                         express provisions of this Trust Preferred Securities
                         Guarantee, and the Trust Preferred Guarantee Trustee
                         shall not be liable except for the performance of such
                         duties and obligations as are specifically set forth in
                         this Trust Preferred Securities Guarantee, and no
                         implied covenants or obligations shall be read into
                         this Trust Preferred Securities Guarantee against the
                         Trust Preferred Guarantee Trustee; and

                    (B)  in the absence of bad faith on the part of the Trust
                         Preferred Guarantee Trustee, the Trust Preferred
                         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 Trust Preferred Guarantee
                         Trustee and conforming to the requirements of this
                         Trust 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 Trust Preferred Guarantee Trustee, the
                         Trust Preferred Guarantee Trustee shall be under a duty
                         to examine the same to determine in good faith whether
                         or not they conform to the requirements of this Trust
                         Preferred Securities Guarantee;

             (ii)   the Trust Preferred Guarantee Trustee shall not be liable
                    for any error of judgment made in good faith by a
                    Responsible Officer of the Trust Preferred Guarantee
                    Trustee, unless it shall be proved that the Trust Preferred
                    Guarantee Trustee was negligent in ascertaining the
                    pertinent facts upon which such judgment was made;

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

             (iv)   no provision of this Trust Preferred Securities Guarantee
                    shall require the Trust Preferred Guarantee Trustee to
                    expend or risk its own funds or

                                       -8-



                    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 Trust Preferred 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 Trust Preferred
                    Securities Guarantee or indemnity, reasonably satisfactory
                    to the Trust Preferred Guarantee Trustee, against such risk
                    or liability is not reasonably assured to it.

     SECTION 3.2    CERTAIN RIGHTS OF TRUST PREFERRED GUARANTEE TRUSTEE.

             (a)    Subject to the provisions of Section 3.1(d) hereof:

             (i)    The Trust Preferred Guarantee Trustee may conclusively 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
                    Trust Preferred Securities Guarantee shall be sufficiently
                    evidenced by an Officers' Certificate.

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

             (iv)   The Trust Preferred Guarantee Trustee shall have no duty to
                    see to any recording, filing or registration of any
                    instrument (or any rerecording, refiling or reregistration
                    thereof).

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

                                       -9-



             (vi)   The Trust Preferred Guarantee Trustee shall be under no
                    obligation to exercise any of the rights or powers vested in
                    it by this Trust Preferred Securities Guarantee at the
                    request or direction of any Holder, unless such Holder shall
                    have provided to the Trust Preferred Guarantee Trustee such
                    security and indemnity, reasonably satisfactory to the Trust
                    Preferred Guarantee Trustee, against the costs, expenses
                    (including reasonable attorneys' fees and expenses and the
                    expenses of the Trust Preferred Guarantee Trustee's agents,
                    nominees or custodians) 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 Trust Preferred Guarantee Trustee; provided that,
                    nothing contained in this Section 3.2(a)(vi) shall be taken
                    to relieve the Trust Preferred Guarantee Trustee, upon the
                    occurrence and during the continuance of an Event of
                    Default, of which the Trust Preferred Guarantee has actual
                    knowledge, of its obligation to exercise the rights and
                    powers vested in it by this Trust Preferred Securities
                    Guarantee.

             (vii)  The Trust Preferred 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 Trust Preferred Guarantee
                    Trustee, in its discretion, may make such further inquiry or
                    investigation into such facts or matters as it may see fit.

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

             (ix)   Any action taken by the Trust Preferred Guarantee Trustee or
                    its agents hereunder shall bind the Holders of the Trust
                    Preferred Securities, and the signature of the Trust
                    Preferred Guarantee Trustee or its agents alone shall be
                    sufficient and effective to perform any such action. No
                    third party shall be required to inquire as to the authority
                    of the Trust Preferred Guarantee Trustee to so act or as to
                    its compliance with any of the terms and provisions of this
                    Trust Preferred Securities Guarantee, both of which shall be
                    conclusively evidenced by the Trust Preferred Guarantee
                    Trustee's or its agent's taking such action.

             (x)    Whenever in the administration of this Trust Preferred
                    Securities Guarantee the Trust Preferred Guarantee Trustee
                    shall deem it desirable to receive instructions with respect
                    to enforcing any remedy or right or taking any other action
                    hereunder, the Trust Preferred Guarantee Trustee (i) may
                    request instructions from the Holders of a Majority in
                    Liquidation

                                      -10-



                    Amount of the Trust Preferred Securities, (ii) may refrain
                    from enforcing such remedy or right or taking such other
                    action until such instructions are received, and (iii) shall
                    be protected in conclusively relying on or acting in good
                    faith in accordance with such instructions.

             (b)    No provision of this Trust Preferred Securities Guarantee
     shall be deemed to impose any duty or obligation on the Trust Preferred
     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 Trust Preferred 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 Trust
     Preferred Guarantee Trustee shall be construed to be a duty.

     SECTION 3.3    NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE.

     The recitals contained in this Guarantee shall be taken as the statements
of the Guarantor, and the Trust Preferred Guarantee Trustee does not assume any
responsibility for their correctness. The Trust Preferred Guarantee Trustee
makes no representation as to the validity or sufficiency of this Trust
Preferred Securities Guarantee.

     SECTION 4.1    TRUST PREFERRED GUARANTEE TRUSTEE; ELIGIBILITY.

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

             (ii)   be an entity organized and doing business under the laws of
                    the United States of America or any State or Territory
                    thereof or of the District of Columbia, or a Person
                    permitted by the Securities and Exchange Commission to act
                    as a resident trustee under the Trust Indenture Act,
                    authorized under such laws to exercise corporate trust
                    powers, having a combined capital and surplus of at least
                    $50,000,000, and subject to supervision or examination by
                    applicable federal, state, territorial or District of
                    Columbia authority. If such Person publishes reports of
                    condition at least annually, pursuant to law or to the
                    requirements of its supervising or examining authority
                    referred to above, then, for the purposes of this Section
                    4.1(a)(ii), the combined capital and surplus of such Person
                    shall be deemed to be its combined capital and surplus as
                    set forth in its most recent report of condition so
                    published.

                                      -11-



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

             (c)    If the Trust Preferred Guarantee Trustee has or shall
     acquire any "conflicting interest" within the meaning of Section 310(b) of
     the Trust Indenture Act and the provisions of the Trust Indenture Act are
     then applicable, the Trust Preferred 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 TRUST PREFERRED

             (a)    Subject to Section 4.2(b), the Trust Preferred Guarantee
     Trustee may be appointed or removed without cause at any time by the
     Guarantor.

             (b)    The Trust Preferred Guarantee Trustee shall not be removed
     in accordance with Section 4.2(a) until a Successor Trust Preferred
     Guarantee Trustee has been appointed and has accepted such appointment by
     written instrument executed by such Successor Trust Preferred Guarantee
     Trustee and delivered to the Guarantor and the Trust Preferred Guarantee
     Trustee.

             (c)    The Trust Preferred Guarantee Trustee appointed to office
     shall hold office until a Successor Trust Preferred Guarantee Trustee shall
     have been appointed or until its removal or resignation. The Trust
     Preferred Guarantee Trustee may at any time resign from office (without
     need for prior or subsequent accounting) by an instrument in writing
     executed by the Trust Preferred Guarantee Trustee and delivered to the
     Guarantor, which resignation shall not take effect until a Successor Trust
     Preferred Guarantee Trustee has been appointed and has accepted such
     appointment by instrument in writing executed by such Successor Trust
     Preferred Guarantee Trustee and delivered to the Guarantor and the
     resigning Trust Preferred Guarantee Trustee.

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

             (e)    No Trust Preferred Guarantee Trustee shall be liable for the
     acts or omissions to act of any Successor Trust Preferred Guarantee
     Trustee.

             (f)    Upon termination of this Trust Preferred Securities
     Guarantee or removal or resignation of the Trust Preferred Guarantee
     Trustee pursuant to this Section 4.2, the Guarantor shall pay to the Trust
     Preferred Guarantee Trustee all documented fees and expenses accrued to the

     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 the Trust), as and when due, regardless of any defense, right of set-off or
counterclaim that the Trust may have or assert. 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 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 Trust Preferred
Securities Guarantee and of any liability to which it applies or may apply,

     any portion of the Distributions, Redemption Price, Liquidation
     Distribution or any other sums payable under the terms of the Trust
     Preferred Securities or the extension of time for the performance of any

     part of the Holders to enforce, assert or exercise any right, privilege,

     receive any approval of the Board of Governors of the Federal Reserve
     System required for the redemption of the Trust Preferred Securities;

             (g)    the settlement or compromise of any obligation guaranteed
     hereby or hereby incurred; or

             (h)    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
consent of, the Guarantor with respect to the happening of any of the foregoing.

     prosecute a legal proceeding directly against the Guarantor to enforce its

     The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Trust in respect of any amounts paid to such Holders by the
Guarantor under this Trust 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

                                      -14-



as a result of payment under this Trust Preferred Securities Guarantee, if, at
the time of any such payment, any amounts are due and unpaid under this Trust
Preferred 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 5.7    INDEPENDENT OBLIGATIONS.

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

(as defined in the Indenture), then

             (a)    the Guarantor shall not, and will not permit any Subsidiary
     to, declare or pay any dividends on, make any distributions with respect
     to, or redeem, purchase, acquire or make a liquidation payment with respect
     to, any of its capital stock (other than (1) dividends or distributions in

     plans for its directors, officers or employees, (4) as a result of a
     reclassification of any class or series of the Guarantor's capital stock
     solely into another class or series of the Guarantor's capital stock, or
     (5) declarations or payments of dividends or distributions payable by a
     Subsidiary of the Guarantor to the Guarantor or any of its Subsidiaries);

             (b)    the Guarantor shall not, and will not permit any Subsidiary
     to, make any payment of interest, principal or premium, if any, or repay,
     repurchase or redeem any debt securities issued by the Guarantor which rank
     pari passu with or junior to the Debentures;

             (c)    the Guarantor shall not make any guarantee payments with
     respect to any guarantee by the Guarantor of the debt securities of any
     Subsidiary of the Guarantor if such guarantee ranks pari passu with or
     junior in interest to the Debentures; provided,

                                      -15-



     however, that the Guarantor may make payments pursuant to its obligations
     under the Trust Preferred Securities Guarantee; and

             (d)    the Guarantor shall not redeem, purchase or acquire less
     than all of the Outstanding (as defined in the Indenture) Debentures or any
     of the Trust Preferred Securities.

     SECTION 6.2    RANKING.

     This Trust Preferred Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank subordinate and junior in right of
payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations,
each as defined in the Indenture, of the Guarantor, to the extent and in the
manner set forth in the Indenture, and the applicable provisions of the
Indenture will apply, in all relevant respects, to the obligations of the
Guarantor hereunder.

payment of the amounts payable in accordance with the Trust Agreement upon
dissolution and liquidation of the Trust, or (c) upon distribution of the
Debentures to the Holders of the Trust Preferred Securities. Notwithstanding the

effective or shall be reinstated, as the case may be, if at any time any Holder
of Trust Preferred Securities must restore payment of any sums paid under the
Trust Preferred Securities or under this Trust Preferred Securities Guarantee.

     for any loss, damage or claim incurred by reason of any act or omission
     performed or omitted by such Indemnified Person in good faith in accordance

     Indemnified Person reasonably believed to be within the scope of the
     authority conferred on such Indemnified Person by this Trust Preferred
     Securities Guarantee or by law, except that an Indemnified Person shall be
     liable for any such loss, damage or claim incurred by reason of such

     acts or omissions.

                                      -16-

     reasonably believes are within such other Person's professional or expert
     competence and who the Indemnified Person reasonably believes has been
     selected with reasonable care by or on behalf of the Guarantor, including
     information, opinions, reports or statements as to the value and amount of
     the assets, liabilities, profits, losses, or any other facts pertinent to
     the existence and amount of assets from which Distributions to Holders of
     Trust Preferred Securities might properly be paid.

     SECTION 8.2    INDEMNIFICATION.

     The Guarantor agrees to indemnify each Indemnified Person for, and to hold
each Indemnified Person harmless against, any loss, liability or expense
incurred without negligence or willful misconduct on its part, arising out of or
in connection with this Trust Preferred Securities Guarantee and the acceptance
or administration of the trust or trusts hereunder, including the costs and
expenses (including reasonable legal fees and expenses) of defending itself
against, or investigating, any claim or liability in connection with the
