         (a) This Guarantee Agreement shall be held by the Trustee for the
benefit of the Holders, and the Trustee shall not transfer this Guarantee
Agreement to any Person except the Trustee shall assign rights hereunder to a
Holder to the extent such assignment is necessary to exercise such Holder's
rights pursuant to Section 5.04 or to a Successor Trustee upon acceptance by

right, title and interest of the Trustee shall automatically vest in any
Successor Trustee, and such vesting and cessation of title shall be effective

shall enforce this Guarantee Agreement for the benefit of the Holders.

         (c) The Trustee, before the occurrence of any Event of Default and
after the curing or waiving of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.06), the
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 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 Trustee shall
                  be determined solely by the express provisions of this
                  Guarantee Agreement, and the Trustee shall not be liable
                  except for the performance of such duties and obligations as
                  are specifically set forth in this Guarantee Agreement; and

                           (B) in the absence of bad faith on the part of the
                  Trustee, the 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
                  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 are specifically
                  required to be furnished to the Trustee, the 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 Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer of the Trustee, unless it
         shall be proved that the Trustee was negligent in ascertaining the
         pertinent facts upon which such judgment was made;

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

                  (iv) no provision of this Guarantee Agreement shall require
         the 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 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 3.02.      Certain Rights of Trustee.

         (a)      Subject to the provisions of Section 3.01:

                  (i) the 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 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;

                  (iii) whenever, in the administration of this Guarantee
         Agreement, the Trustee shall deem it desirable that a matter be proved
         or established before taking, suffering or omitting any action
         hereunder, the 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,
         shall be promptly delivered by the Guarantor;

                  (iv) the Trustee may consult with counsel of its choice, 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 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 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 Trustee such adequate security and indemnity as would
         satisfy a reasonable person in the position of the 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 Trustee; provided that nothing contained in this Section 3.02(a)(v)
         shall be taken to relieve the 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 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 Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit;

                  (vii) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or

         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder; and

                  (viii) whenever in the administration of this Guarantee
         Agreement the Trustee shall deem it desirable to receive instructions
         with respect to enforcing any remedy or right or taking any other
         action hereunder, the Trustee (i) may request instructions from the
         Holders, (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 acting in accordance with such instructions.

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

         SECTION 3.03.  Compensation; Fees; Indemnity.

         The Guarantor agrees:

         (a) to pay to the Trustee from time to time reasonable compensation for
all services rendered by the Trustee hereunder (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
Trustee upon request for all reasonable expenses, disbursements and advances
incurred or made by the 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 Trustee for, and to hold the Trustee harmless
against, any and all loss, damage, claims, liability or expense incurred without
negligence or bad faith on its part, 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 provisions of this Section 3.03 shall survive the termination of this
Guarantee Agreement.

                                     TRUSTEE

         SECTION 4.01.  Trustee; Eligibility.

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

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

                  (ii) be a corporation 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 corporation or Person permitted by
         the Securities and Exchange Commission to act as an institutional
         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 million U.S. dollars ($50,000,000), and subject to
         supervision or examination by Federal, State, Territorial or District
         of Columbia authority. If such corporation publishes reports of
         condition at least annually, pursuant to law or to the requirements of
         the supervising or examining authority referred to above, then, for the
         purposes of this Section 4.01(a)(ii), 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 Trustee shall cease to be eligible to so act
under Section 4.01(a), the Trustee shall immediately resign in the manner and
with the effect set out in Section 4.02(c).

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

     SECTION 4.02. Appointment, Removal and Resignation of Trustee.

     (a) Subject to Section  4.02(b),  the Trustee may be  appointed  or removed
without cause at any time by the Guarantor.

         (b) The Trustee shall not be removed until a Successor Trustee has been
appointed and has accepted such appointment by written instrument executed by
such Successor Trustee and delivered to the Guarantor.

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

         (d) If no Successor Trustee shall have been appointed and accepted
appointment as provided in this Section 4.02 within 60 days after delivery to
the Guarantor of an instrument of resignation, the resigning Trustee may
petition any court of competent jurisdiction for appointment of a Successor
Trustee. Such court may thereupon, after prescribing such notice, if any, as it
may deem proper, appoint a Successor Trustee.

                                    GUARANTEE

     SECTION 5.01.  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  Trust),  as and when due,
regardless of any defense,  right of set-off or counterclaim which the Guarantor
may have or assert  against any Person.  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  5.02.  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 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 5.03.  Obligations Not Affected. The obligation of the Guarantor to
make the Guarantee  Payments 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:

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

         (b) the extension of time for the payment by the Trust of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sum payable that results from the extension of any interest payment period on
the Junior Subordinated Notes 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 Trust 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 Trust or any of the assets of the
Trust;

     (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 5.03 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

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

     SECTION 5.04. Rights of Holders. The Guarantor expressly acknowledges that:
(i) this  Guarantee  Agreement will be deposited with the Trustee to be held for
the  benefit of the  Holders;  (ii) the  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  Preferred  Securities  have the right to direct  the
time,  method and place of conducting any proceeding for any remedy available to
the Trustee in respect of this  Guarantee  Agreement or exercising  any trust or
power conferred upon the Trustee under this Guarantee  Agreement,  provided that
such  direction  shall  not be in  conflict  with any  rule of law or with  this
Guarantee Agreement,  and could not involve the Trustee in personal liability in
circumstances  where  reasonable  indemnity would not be adequate;  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 or requesting or directing that action be taken by the
Trustee or any other  Person;  it being  understood  and intended that no one or
more of such Holders shall have any right in any manner whatsoever by virtue of,
or by availing of, any provision of this Guarantee Agreement to affect,  disturb
or prejudice  the rights of any other of such Holders or to obtain or to seek to
obtain  priority or preference  over any other of such Holders or to enforce any
right under this Guarantee  Agreement,  except in the manner herein provided and
for the equal and ratable benefit of all of such Holders.

     SECTION 5.05.  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)  or upon  the  distribution  of  Junior  Subordinated  Notes to the
Holders in exchange for all of the Preferred Securities.

     SECTION 5.06.  Subrogation.  The  Guarantor  shall be subrogated to all (if
any) rights of the Holders  against the 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 of Guarantee  Payments 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 5.07. Independent Obligations.  The Guarantor acknowledges that its
obligations  hereunder  are  independent  of the  obligations  of the Trust 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 Guarantee  Agreement  notwithstanding  the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03 hereof.

                                   ARTICLE VI

                                  SUBORDINATION

     SECTION  6.01.Subordination.  This Guarantee  Agreement 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
Junior  Subordinated  Notes,  except those  obligations or liabilities made pari
passu or  subordinate  by their  terms,  (ii) pari  passu  with the most  senior
preferred or preference  stock now or hereafter issued by the Guarantor and with
any guarantee  now or hereafter  entered into by the Guarantor in respect of any
preferred or preference securities of any Affiliate of the Guarantor,  and (iii)
senior to all common stock of the Guarantor.

                                   ARTICLE VII

                                   TERMINATION

     SECTION 7.01. Termination.  This Guarantee Agreement shall terminate and be
of no further force and effect upon: (i) full payment of the Redemption Price of
all Preferred Securities,  (ii) the distribution of Junior Subordinated Notes to
the  Holders in  exchange  for all of the  Preferred  Securities,  or (iii) full
payment of the  amounts  payable in  accordance  with the Trust  Agreement  upon
liquidation  of  the  Trust.   Notwithstanding  the  foregoing,  this  Guarantee
Agreement 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 Securities or under this Guarantee Agreement.
