the withholding of such notice is in the interests of the Holders of the
Securities.

          (b)  The Guarantee Trustee shall not be deemed to have knowledge of
any Guarantee Event of Default unless the Guarantee Trustee shall have received
written notice thereof from the Guarantor or a Holder or a Responsible Officer

accountable by reason of mailing any material pursuant to a request made under
Section 312(b) of the Trust Indenture Act.

          SECTION 2.10 GUARANTEE TRUSTEE MAY FILE PROOFS OF CLAIM. Upon the
occurrence of a Guarantee Event of Default, the Guarantee Trustee is hereby
authorized to (a) recover judgment, in its own name and as trustee of an express
trust, against the Guarantor for the whole amount of any Guarantee Payments
remaining unpaid and (b) file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have its claims and those of the
Holders of the Securities allowed in any judicial proceedings relative to the
Guarantor, its creditors or its property.

                                   ARTICLE 3

                         POWERS, DUTIES AND RIGHTS OF
                               GUARANTEE TRUSTEE

          SECTION 3.1 POWERS AND DUTIES OF GUARANTEE TRUSTEE.

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

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

          (c)  The Guarantee Trustee, before the occurrence of any Guarantee
Event of Default and after the curing of all Guarantee Events of Default that
may have occurred, shall undertake to perform only such duties as are
specifically set forth in this Guarantee, and no implied covenants shall be read
into this Guarantee against the Guarantee Trustee. In case a Guarantee Event of
Default has occurred (that has not been cured or waived

                                       8
<PAGE>

pursuant to Section 2.6) and is actually known to a Responsible Officer of the
Guarantee Trustee, the Guarantee Trustee shall exercise such of the rights and
powers vested in it by this 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.

          (d)  No provision of this Guarantee 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 Guarantee Event of Default
          and after the curing or waiving of all such Guarantee 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, 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, and no implied
               covenants or obligations shall be read into this Guarantee
               against the Guarantee Trustee; 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; but in the case of any such
               certificates or opinions that by any provision hereof 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;

               (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 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; and

               (iv)    no provision of this Guarantee 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

                                       9
<PAGE>

     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 or if the Guarantee Trustee
     shall have reasonable grounds for believing that an indemnity, reasonably
     satisfactory to the Guarantee Trustee, against such risk or liability is
     not reasonably assured to it under the terms of this Guarantee.

     SECTION 3.2  CERTAIN RIGHTS OF GUARANTEE TRUSTEE.

     (a)  Subject to the provisions of Section 3.1:

               (i)    The 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 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 shall be sufficiently evidenced by an Officers' Certificate;

               (iii)  Whenever, in the administration of this Guarantee, the
     Guarantee Trustee shall deem it desirable that a matter be proved or
     established before taking, suffering or omitting 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 conclusively rely
     upon an Officers' Certificate which, upon receipt of such request, shall be
     promptly delivered by the Guarantor;

               (iv)   The Guarantee Trustee shall have no duty to see to any
     recording, filing or registration or any instrument (or any rerecording,
     refiling or re-registration thereof);

               (v)    The Guarantee Trustee may consult with counsel, and the
     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
     Guarantee Trustee shall have the right at any time to seek instructions
     concerning the administration of this Guarantee from any court of competent
     jurisdiction;

               (vi)   The Guarantee Trustee shall be under no obligation to
     exercise any of the rights or powers vested in it by this Guarantee at the
     request or direction of any Holder, unless such Holder shall have provided
     to the Guarantee Trustee such security and indemnity, reasonably
     satisfactory to the Guarantee Trustee, against the costs, expenses
     (including attorneys' fees and expenses and the expenses of

                                      10
<PAGE>

     the 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 Guarantee
     Trustee; provided, that nothing contained in this Section 3.2(a)(vi) shall
     be taken to relieve the Guarantee Trustee, upon the occurrence of a
     Guarantee Event of Default, of its obligation to exercise the rights and
     powers vested in it by this Guarantee in the manner provided by Section
     3.1(c);

          (vii)     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;

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

     part of any agent or attorney appointed with due care by it hereunder;

          (ix)      Any action taken by the Guarantee Trustee or its agents
     hereunder shall bind the Holders, and the signature of the 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 Guarantee Trustee to so act or as to its compliance with
     any of the terms and provisions of this Guarantee, both of which shall be
     conclusively evidenced by the Guarantee Trustee's or its agent's taking
     such action; and

          (x)       Whenever in the administration of this Guarantee, 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 written instructions from
     the Holders of a Majority in Liquidation Amount of the Securities, (B) may
     refrain from enforcing such remedy or right or taking such other action
     until such written instructions are received and (C) shall be protected in
     conclusively relying on or acting in accordance with such written
     instructions.

     (b)  No provision of this Guarantee 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 to act 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.

         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 Guarantee Trustee does not assume any responsibility for
their correctness. The Guarantee Trustee makes no representations as to the
validity or sufficiency of this Guarantee.

                                    ARTICLE 4

                                GUARANTEE TRUSTEE

         SECTION 4.1  GUARANTEE TRUSTEE; ELIGIBILITY.

         (a) There shall be at all times a Guarantee 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 other 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 4.1(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 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).

         (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, subject to the penultimate
paragraph thereof.

         SECTION 4.2  APPOINTMENT, REMOVAL AND RESIGNATION OF GUARANTEE TRUSTEE.

         (a)   Subject to Section 4.2(b), unless a Guarantee Event of Default
shall have occurred and be continuing, the Guarantee Trustee may be appointed or
removed with or without cause at any time by the Guarantor. If a Guarantee Event
of Default has occurred

                                      12
<PAGE>

and is continuing, the Guarantee Trustee may be appointed or removed by the
Holders of a Majority in Liquidation Amount of the Preferred Securities.

         (b)   The Guarantee Trustee shall not be removed in accordance with
Section 4.2(a) 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.

         (c)   The Guarantee Trustee appointed to office shall hold such office
until a Successor Guarantee Trustee shall have been appointed or until its
removal or resignation. The Guarantee Trustee may resign from office (without
need for prior or subsequent accounting) by an instrument in writing executed by
the Guarantee Trustee and delivered to the Guarantor, which resignation shall
not take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and 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 Guarantor of an instrument of removal or resignation, the
removed or resigning Guarantee Trustee may petition 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)   No Guarantee Trustee shall be liable for the acts or omissions to
act of any Successor Guarantee Trustee.

         (f)   Upon termination of this Guarantee or removal or resignation of
the Guarantee Trustee pursuant to this Section 4.2, the Guarantor shall pay to
the Guarantee Trustee all amounts owing for fees and reimbursement of expenses
which have accrued to the date of such termination, removal or resignation.

         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. Notwithstanding anything to the

                                      13
<PAGE>

contrary herein, the Guarantor retains all of its rights under the Indenture to
(i) extend the interest payment period on the Junior Subordinated Debt
Securities pursuant to Section 2.10 thereof and the Guarantor shall not be
obligated hereunder to make any Guarantee Payments during any Extension Period
(as defined in the certificate evidencing the Junior Subordinated Debt
Securities) with respect to the Distributions (as defined in the Trust
Agreement) on the Securities and (ii) change the maturity date of the Junior
Subordinated Debt Securities to the extent permitted by the Indenture.

         SECTION 5.2 WAIVER OF NOTICE AND DEMAND.

         The Guarantor hereby waives notice of acceptance of this 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 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 shall be absolute and unconditional and shall remain in
full force and effect until the entire liquidation amount of all outstanding
Securities shall have been paid and such obligation shall in no way be affected
or impaired by reason of the happening from time to time of any event, including
without limitation, the following, whether or not with notice to, or the consent
of, the Guarantor:

         (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 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 Securities or the extension of time
for the performance of any other obligation under, arising out of, or in
connection with the 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 Debt Securities or any change to the maturity date of the Junior
Subordinated Debt Securities permitted by the Indenture);

         (c)   Any failure, omission, delay or lack of diligence on the part of
the Property Trustee or the Holders to enforce, assert or exercise any right,
privilege, power or remedy conferred on the Property Trustee or the Holders
pursuant to the terms of the 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,

                                      14
<PAGE>

reorganization, arrangement, composition or readjustment of debt of, or other
similar proceedings affecting, the Trust or any of the a sets of the Trust;

         (e)   Any invalidity of, or defect or deficiency in, the 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 Guarantee Trustee or the Holders to
give notice to, or obtain consent of the Guarantor or any other Person with
respect to the happening of any of the foregoing.

         No setoff, counterclaim, reduction or diminution of any obligation, or
any defense of any kind or nature that the Guarantor has or may have against any
Holder shall be available hereunder to the Guarantor against such Holder to
reduce the payments to it under this Guarantee.

         SECTION 5.4 RIGHTS OF HOLDERS.

         (a)   The Holders of at least a Majority in Liquidation Amount of the
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 or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under this Guarantee, provided, that, subject to Section 3.1,
the Guarantee Trustee shall have the right to decline to follow any such
direction if the Guarantee Trustee shall determine that the action so directed
would be unjustly prejudicial to the Holders not taking part in such direction
or if the Guarantee Trustee being advised by counsel determines that the action
or proceeding so directed may not lawfully be taken or if the Guarantee Trustee
in good faith by its board of directors or trustees, executive committee, or a
trust committee of directors or trustees and/or Responsible Officers of the
Guarantee Trustee shall determine that the action or proceedings so directed
would involve the Guarantee Trustee in personal liability.

         (b)   If the Guarantee Trustee fails to enforce this Guarantee, then
any Holder of Securities may, subject to the subordination provisions of Section
6.2, institute a legal proceeding directly against the Guarantor to enforce the
Guarantee Trustee's rights under this Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. In addition, if the Guarantor has failed to make a Guarantee Payment, a
Holder of Securities may, subject to the subordination provisions of Section
6.2, directly institute a proceeding against the Guarantor for enforcement of

                                      15
<PAGE>

the Guarantee for such payment to the Holder of the Securities of the principal
of or interest on the Junior Subordinated Debt Securities on or after the
respective due dates specified in the Junior Subordinated Debt Securities, and
the amount of the payment will be based on the Holder's pro rata share of the
amount due and owing on all of the Securities. The Guarantor hereby waives any
right or remedy to require that any action on this Guarantee be brought first
against the Trust or any other person or entity before proceeding directly
against the Guarantor.

         SECTION 5.5 GUARANTEE OF PAYMENT.

         This Guarantee creates a guarantee of payment and not of collection.

         SECTION 5.6  SUBROGATION.

         The Guarantor shall be subrogated to all (if any) rights of the Holders
of Securities against the Trust in respect of any amounts paid to such Holders
by the Guarantor under this 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 Guarantee, if at the time of any such payment,
any amounts are due and unpaid under this 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
Guarantee Trustee for the benefit of 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 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 notwithstanding the
occurrence of any event referred to in subsections 5.3(a) through 5.3(g),
inclusive, hereof.

Subordinated Debt Securities, (ii) there shall be a Guarantee Event of Default
or (iii) the Guarantor shall have given notice of its election of an Extension
Period as provided in the certificate evidencing the Junior Subordinated Debt
Securities and shall not have rescinded such notice, or such Extension Period or
any extension thereof shall be continuing, then the

<PAGE>

Guarantor shall not, and shall not permit any subsidiary of the Guarantor, to
(x) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of the Guarantor's
capital stock or (y) make any payment of principal, interest or premium, if any,
on or repay, repurchase or redeem any debt securities of the Guarantor that rank
on a parity with or junior in interest to the Junior Subordinated Debt
Securities or 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 on a parity with or junior in interest to the Junior
Subordinated Debt Securities (other than (a) dividends or distributions in
common stock of the Guarantor, (b) any declaration of a dividend in connection
with the implementation of a shareholders' rights plan, or the issuance of stock
under any such plan in the future, or the redemption or repurchase of any such
rights pursuant thereto, (c) payments under this Guarantee, and (d) purchases of
common stock related to the issuance of common stock or rights under any of the
Guarantor's benefit plans).

         SECTION 6.2  RANKING.

         This Guarantee will constitute an unsecured obligation of the Guarantor
and will rank subordinate and junior in right of payment to all Senior
Indebtedness of the Company (as defined in the Indenture) of the Guarantor in
the same manner and to the same extent as set forth in Article XIV of the
Indenture.

         SECTION 6.3 SUBORDINATION OF COMMON SECURITIES.

         If a Trust Enforcement Event has occurred and is continuing under the
Trust Agreement, the rights of the holders of the Common Securities to receive
Guarantee Payments hereunder shall be subordinated to the rights of the Holders
of the Preferred Securities to receive Guarantee Payments under this Guarantee.

                                    ARTICLE 7

                                   TERMINATION

         SECTION 7.1  TERMINATION.

         This Guarantee shall terminate upon (i) full payment of the Redemption
Price of all Securities, (ii) distribution of the Junior Subordinated Debt
Securities to the Holders of all the Securities or (iii) full payment of the
