SECTION 2.1.   Powers and Duties of the Guarantee Trustee.

         (a)   This Guarantee shall be held by the Guarantee Trustee for the
benefit of the Holders of the Capital Securities, and the Guarantee Trustee
shall not transfer this Guarantee to any Person except a Holder of Capital
Securities exercising his or her rights pursuant to Section 4.4(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 shall automatically vest in any Successor
Guarantee Trustee, and such vesting and cessation of title shall be effective

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

         (c)   The Guarantee 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, and no implied covenants shall be read into this
Guarantee against the Guarantee Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.4(b)) 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 Event of Default and after
         the curing or waiving of all Events of Default that may have occurred:

                                       192
<PAGE>

                      (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 furnished to the Guarantee Trustee, the
               Guarantee Trustee shall be under a duty to examine the same to
               determine whether or not on their face 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 such Responsible Officer of the
         Guarantee Trustee or 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 written 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; 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 powers, if the Guarantee Trustee shall
         have reasonable grounds for believing that the repayment of such funds
         is not reasonably assured to it under the terms of this Guarantee, or
         security and indemnity, reasonably satisfactory to the Guarantee
         Trustee, against such risk or liability is not reasonably assured to
         it.

SECTION 2.2.   Certain Rights of the Guarantee Trustee.
               ---------------------------------------

         (a)   Subject to the provisions of Section 2.1:

               (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.

                                       193
<PAGE>

               (ii)   Any direction or act of the Guarantor contemplated by this
         Guarantee shall be sufficiently evidenced by an Officer's 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 Officer's Certificate of the Guarantor 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 of any instrument or other writing
         (or any rerecording, refiling or reregistration thereof).

               (v)    The Guarantee Trustee may consult with counsel of its
         selection, 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
         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, however, that nothing contained in
         this Section 2.2(a)(vi) 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.

               (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 through agents, nominees, custodians or attorneys, and the Guarantee
         Trustee shall not be

               194
<PAGE>

         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 Guarantee Trustee or its agents
         hereunder shall bind the Holders of the Capital Securities, 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.

               (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 instructions from the
         Holders of a Majority in liquidation amount of the Capital Securities,
         (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 conclusively relying on or acting in accordance with such
         instructions.

               (xi)   The Guarantee Trustee shall not be liable for any action
         taken, suffered, or omitted to be taken by it in good faith and
         reasonably believed by it to be authorized or within the discretion or
         rights or powers conferred upon it by this Guarantee.

         (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 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 2.4.   Events of Default; Waiver.
               -------------------------

         (a)   An Event of Default under this Guarantee will occur upon the

         (b)   The Holders of a Majority in liquidation amount of the Capital
Securities may, voting or consenting as a class, on behalf of the Holders of all
of the Capital Securities, waive any past Event of Default and its consequences.
Upon such waiver, any such Event of Default shall cease to exist, and shall be
deemed to have been cured, for every purpose of this

                                       195

Guarantee, but no such waiver shall extend to any subsequent or other default or

               -------------------------

         (a)   The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders of the Capital Securities, notices of all Events of Default actually
known to a Responsible Officer of the Guarantee Trustee, unless such defaults
have been cured before the giving of such notice, provided, however, that the
Guarantee Trustee shall be protected in withholding such notice if and so long
as a Responsible Officer of the Guarantee Trustee in good faith determines that
the withholding of such notice is in the interests of the Holders of the Capital
Securities.

         (b)   The Guarantee Trustee shall not be charged with knowledge of any
Event of Default unless the Guarantee Trustee shall have received written notice
thereof from the Guarantor or a Holder of the Capital Securities, or a
Responsible Officer of the Guarantee Trustee charged with the administration of
this Guarantee shall have actual knowledge thereof.

         of such corporation or national association 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 3.1(a), the Guarantee Trustee shall immediately resign

         (c)   If the Guarantee Trustee has or shall acquire any "conflicting

               -------------------------------------------------------------

         (a)   Subject to Section 3.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor except during an Event of
Default.

         (b)   The Guarantee Trustee shall not be removed in accordance with

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 office until
a Successor Guarantee Trustee shall have been appointed or until its removal or

take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by an 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 3.2 within 60 days after
delivery of an instrument of removal or resignation, the Guarantee Trustee
resigning or being removed 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.

act of any Successor Guarantee Trustee.

                                    GUARANTEE

SECTION 4.1.   Guarantee.
               ---------

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

         (b)   The Guarantor hereby also agrees to assume any and all
Obligations of the Issuer and in the event any such Obligation is not so
assumed, subject to the terms and conditions hereof, the Guarantor hereby
irrevocably and unconditionally guarantees to each Beneficiary the

                                       197
<PAGE>

full payment, when and as due, of any and all Obligations to such Beneficiaries.
This Guarantee is intended to be for the Beneficiaries who have received notice
hereof.

SECTION 4.2.   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 Issuer or any other
Person before proceeding against the Guarantor, protest, notice of nonpayment,
notice of dishonor, notice of redemption and all other notices and demands.

SECTION 4.3.   Obligations Not Affected.
               ------------------------

         The obligations, covenants, agreements and duties of the Guarantor
under this Guarantee shall in no way be affected or impaired by reason of the
happening from time to time of any of the following:

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

         (b)   the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Special 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
(other than an extension of time for the payment of the Distributions,
Redemption Price, Special Redemption Price, Liquidation Distribution or other
sums payable that results from the extension of any interest payment period on
the Debentures or any extension of the maturity date of the Debentures 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 Capital Securities, or any
action on the part of the Issuer granting indulgence or extension of any kind;

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

         (e)   any invalidity of, or defect or deficiency in, the 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, it being the intent of
this Section 4.3 that the

                                       198
<PAGE>

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 4.4.   Rights of Holders.
               -----------------

         (a)   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 or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under this Guarantee; provided, however, that (subject to
Sections 2.1 and 2.2) the Guarantee Trustee shall have the right to decline to
follow any such direction if the Guarantee Trustee shall determine that the
actions so directed would be unjustly prejudicial to the Holders not taking part
in such direction or if the Guarantee Trustee being advised by legal 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 shall determine that the action or proceeding so directed
would involve the Guarantee Trustee in personal liability.

         (b)   Any Holder of Capital Securities may 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 Issuer,
the Guarantee Trustee or any other Person. The Guarantor waives any right or
remedy to require that any such action be brought first against the Issuer, the
Guarantee Trustee or any other Person before so proceeding directly against the
Guarantor.

SECTION 4.5.   Guarantee of Payment.
               --------------------

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

SECTION 4.6.   Subrogation.
               -----------

         The Guarantor shall be subrogated to all (if any) rights of the Holders
of Capital Securities against the Issuer 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 applicable 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, after giving effect to 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 Holders.

SECTION 4.7.   Independent Obligations.
               -----------------------

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Capital
Securities and that the Guarantor shall be liable as principal

                                       199
<PAGE>

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
(a) through (g), inclusive, of Section 4.3 hereof.

SECTION 4.8.   Enforcement.
               -----------

         A Beneficiary may enforce the Obligations of the Guarantor contained in
Section 4.1(b) directly against the Guarantor, and the Guarantor waives any
right or remedy to require that any action be brought against the Issuer or any
other person or entity before proceeding against the Guarantor.

         The Guarantor shall be subrogated to all rights (if any) of any
Beneficiary against the Issuer in respect of any amounts paid to the
Beneficiaries by the Guarantor under this Guarantee; provided, however, that the
Guarantor shall not (except to the extent required by applicable provisions of
law) be entitled to enforce or exercise any rights 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, after giving effect to such
payment, any amounts are due and unpaid under this Guarantee.

               --------------------------

         So long as any Capital Securities remain outstanding, if (a) there
shall have occurred and be continuing an Event of Default or (b) the Guarantor
shall have selected an Extension Period as provided in the Declaration and such
period, or any extension thereof, shall have commenced and be continuing, then
the Guarantor may not (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 of or
interest or premium, if any, on or repay, repurchase or redeem any debt

of the Guarantor (A) in connection with any employment contract, benefit plan or
other similar arrangement with or for the benefit of one or more employees,

reinvestment or stockholder stock purchase plan or (C) in connection with the
issuance of capital stock of the Guarantor (or securities convertible into or
exercisable for such capital stock), as consideration in an acquisition
transaction entered into prior to the occurrence of the Event of Default or the
applicable Extension Period, (iii) as a result of any exchange or conversion of
any class or series of the Guarantor's capital stock (or any capital stock of a
subsidiary of the Guarantor) for any class or series of the Guarantor's capital
stock or of any class or series of the Guarantor's indebtedness for any class or
series of the Guarantor's capital stock, (iv) the purchase of fractional
interests in shares of the Guarantor's capital stock pursuant to the conversion
or exchange provisions of such capital stock or the security being converted or
exchanged, (v) any declaration of a dividend in connection with any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or

                                       200
<PAGE>

repurchase of rights pursuant thereto, or (vi) any dividend in the form of
stock, warrants, options or other rights where the dividend stock or the stock
issuable upon exercise of such warrants, options or other rights is the same
stock as that on which the dividend is being paid or ranks pari passu with or
junior to such stock).

SECTION 5.2.   Ranking.
               -------

         This Guarantee will constitute an unsecured obligation of the Guarantor
and will rank subordinate and junior in right of payment to all present and
future Senior Indebtedness (as defined in the Indenture) of the Guarantor. By
their acceptance thereof, each Holder of Capital Securities agrees to the
foregoing provisions of this Guarantee and the other terms set forth herein.

full payment of the Redemption Price or the Special Redemption Price, as the
case may be, of all Capital Securities then outstanding, (ii) upon the
distribution of all of the Debentures to the Holders of all of the Capital
Securities or (iii) upon full payment of the amounts payable in accordance with
the Declaration upon dissolution of the Issuer. This Guarantee will continue to
be effective or will be reinstated, as the case may be, if at any time any
Holder of Capital Securities must restore payment of any sums paid under the
Capital Securities or under this Guarantee.

                                   ARTICLE VII
                                 INDEMNIFICATION

SECTION 7.1.   Exculpation.
               -----------

         (a)   No Indemnified Person shall be liable, responsible or accountable
in damages or otherwise to the Guarantor or any Covered Person for any loss,
damage or claim incurred by reason of any act or omission of such Indemnified
Person in good faith in accordance with this Guarantee and in a manner that such
Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Guarantee or by law, except that an
Indemnified Person shall be liable for any such loss, damage or claim incurred
by reason of such Indemnified Person's negligence or willful misconduct with
respect to such acts or omissions.

         (b)   An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Issuer or the Guarantor and upon such information,
opinions, reports or statements presented to the Issuer or the Guarantor by any
Person as to matters the Indemnified Person reasonably believes are within such
other Person's professional or expert competence and who, if selected by such
Indemnified Person, has been selected with reasonable care by such Indemnified
Person, 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

                                       201
<PAGE>

amount of assets from which Distributions to Holders of Capital Securities might
properly be paid.

SECTION 7.2.   Indemnification.
               ---------------

         (a)   The Guarantor agrees to indemnify each Indemnified Person for,
and to hold each Indemnified Person harmless against, any and all loss,
liability, damage, claim or expense incurred without negligence or willful
misconduct on the part of the Indemnified Person, arising out of or in
connection with the acceptance or administration of the trust or trusts
hereunder, including but not limited to the costs and expenses (including
reasonable legal fees and expenses) of the Indemnified Person defending itself
against, or investigating, any claim or liability in connection with the
exercise or performance of any of the Indemnified Person's powers or duties
hereunder. The obligation to indemnify as set forth in this Section 7.2 shall
survive the resignation or removal of the Guarantee Trustee and the termination
of this Guarantee.

         (b)   Promptly after receipt by an Indemnified Person under this
Section 7.2 of notice of the commencement of any action, such Indemnified Person
will, if a claim in respect thereof is to be made against the Guarantor under
this Section 7.2, notify the Guarantor in writing of the commencement thereof;
but the failure so to notify the Guarantor (i) will not relieve the Guarantor
from liability under paragraph (a) above unless and to the extent that the
Guarantor did not otherwise learn of such action and such failure results in the
forfeiture by the Guarantor of substantial rights and defenses and (ii) will
not, in any event, relieve the Guarantor from any obligations to any Indemnified
Person other than the indemnification obligation provided in paragraph (a)
above. The Guarantor shall be entitled to appoint counsel of the Guarantor's
choice at the Guarantor's expense to represent the Indemnified Person in any
action for which indemnification is sought (in which case the Guarantor shall
not thereafter be responsible for the fees and expenses of any separate counsel
retained by the Indemnified Person or Persons except as set forth below);
provided, however, that such counsel shall be satisfactory to the Indemnified
Person. Notwithstanding the Guarantor's election to appoint counsel to represent
the Indemnified Person in any action, the Indemnified Person shall have the
right to employ separate counsel (including local counsel), and the Guarantor
shall bear the reasonable fees, costs and expenses of such separate counsel, if
(i) the use of counsel chosen by the Guarantor to represent the Indemnified
Person would present such counsel with a conflict of interest, (ii) the actual
or potential defendants in, or targets of, any such action include both the
Indemnified Person and the Guarantor and the Indemnified Person shall have
reasonably concluded that there may be legal defenses available to it and/or
other Indemnified Persons which are different from or additional to those
available to the Guarantor, (iii) the Guarantor shall not have employed counsel
satisfactory to the Indemnified Person to represent the Indemnified Person
within a reasonable time after notice of the institution of such action or (iv)
the Guarantor shall authorize the Indemnified Person to employ separate counsel
at the expense of the Guarantor. The Guarantor will not, without the prior
written consent of the Indemnified Persons, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the Indemnified Persons are actual or
potential parties to such claim or action) unless such settlement,

                                       202
<PAGE>

compromise or consent includes an unconditional release of each Indemnified
Person from all liability arising out of such claim, action, suit or proceeding.

SECTION 7.3.   Compensation; Reimbursement of Expenses.
               ---------------------------------------

         The Guarantor agrees:

         (a)   to pay to the Guarantee Trustee from time to time such
compensation for all services rendered by it hereunder as the parties shall
agree to 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); and

         (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 it in accordance with any provision of this
Guarantee (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 willful misconduct.

         The provisions of this Section 7.3 shall survive the resignation or
removal of the Guarantee Trustee and the termination of this Guarantee.

the successors, assigns, receivers, trustees and representatives of the
Guarantor and shall inure to the benefit of the Holders of the Capital
Securities then outstanding. Except in connection with any merger or
consolidation of the Guarantor with or into another entity or any sale, transfer
or lease of the Guarantor's assets to another entity, in each case to the extent
permitted under the Indenture, the Guarantor may not assign its rights or
delegate its obligations under this Guarantee without the prior approval of the
Holders of not less than a Majority in liquidation amount of the Capital
Securities.

SECTION 8.2.   Amendments.
               ----------

         Except with respect to any changes that do not adversely affect the
rights of Holders of the Capital Securities in any material respect (in which
case no consent of Holders will be required), this Guarantee may be amended only
with the prior approval of the Holders of not less than a Majority in
liquidation amount of the Capital Securities. The provisions of the Declaration
with respect to amendments thereof shall apply equally with respect to
amendments of the Guarantee.
