failure to act, or its own willful misconduct, except that:

                  (i) prior to the occurrence of any Event of Default and after

                  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

         Officer of the Guarantee Trustee or the Guarantee Trustee was negligent
         in ascertaining the pertinent facts upon which such judgment was made;

<PAGE>

                  (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 relating to the exercise of 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 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.

                  (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 any
         re-recording, refiling or re-registration 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.

                                       6

                  (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 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 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 (i) may request instructions from the
         Holders of a Majority in liquidation amount of the Capital 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 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, without
         negligence, 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 2.3. 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
representation as to the validity or sufficiency of this Guarantee.

         Section 2.4. Events of Default; Waiver.

         (a) An Event of Default under this Guarantee will occur upon the
failure of the Guarantor to perform any of its payment or other obligations
hereunder.

         (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 Guarantee, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

         Section 2.5. Events of Default; Notice.

         (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 and the Guarantor, 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 deemed to have knowledge of any
Event of Default unless the Guarantee Trustee shall have received written notice
from the Guarantor or a Holder of the Capital Securities (except in the case of
a payment default), or a Responsible Officer of the Guarantee Trustee charged
with the administration of this Guarantee shall have obtained actual knowledge
thereof.

                                  ARTICLE III.

         Section 3.1. Guarantee Trustee; Eligibility.

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

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

                  (ii) be a corporation organized and doing business under the

         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 3.1(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 3.1(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 3.2(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 shall either eliminate such interest or resign to the extent
and in the manner provided by, and subject to this Guarantee.

         Section 3.2. Appointment, Removal and Resignation of Guarantee Trustee.

         (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
Section 3.2(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 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 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.

         (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 3.2, the Guarantor shall pay to the
Guarantee Trustee all amounts owing to the Guarantee Trustee under Sections 7.2

                                    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 the 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 full payment, when and as
due, of any and all Obligations to such Beneficiaries. This Guarantee is
intended to be for the benefit of, and to be enforceable by, all such
Beneficiaries, whether or not such Beneficiaries 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, Optional 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 payment of Distributions, Optional
Redemption Price, Special Redemption Price, Liquidation Distribution or other
sum 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);

                                       10
<PAGE>

         (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 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
Section 2.1) the Guarantee Trustee shall have the right to decline to follow any
such direction 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
committees or a trust committee of directors or trustees and/or Responsible
Officers shall determine that the action or proceedings 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.

                                       11
<PAGE>

         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 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, 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 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 by a Beneficiary.

         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 mandatory 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
at the time of any such payment, and after giving effect to such payment, any
amounts are due and unpaid under this Guarantee.

                                   ARTICLE V.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

         Section 5.1. Limitation of Transactions.

         So long as any Capital Securities remain outstanding, if (a) there
shall have occurred and be continuing an Event of Default or a Declaration 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 shall not and shall not
permit any Affiliate of the Guarantor controlled by 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 or such
Affiliate's capital stock (other than payments of dividends or distributions to
the Guarantor or a Subsidiary of the Guarantor) or make any guarantee payments
with respect to the foregoing; or (y) make any payment of principal of or

                                       12
<PAGE>

interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Guarantor or any Affiliate of the Guarantor controlled by the
Guarantor that rank pari passu in all respects with or junior in interest to the
Debentures (other than, with respect to clauses (x) and (y) above, (i)
repurchases, redemptions or other acquisitions of shares of capital stock of the
Guarantor or any Subsidiary of the Guarantor in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of
one or more employees, officers, directors or consultants, in connection with a
dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Guarantor or of such Subsidiary (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, Declaration Event of Default or Extension Period, as
applicable, (ii) 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 in
the case of a Subsidiary of the Guarantor, any class or series of such
Subsidiary'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 (or in the
case of indebtedness of a Subsidiary of the Guarantor, of any class or series of
such Subsidiary's indebtedness for any class or series of such Subsidiary's
capital stock), (iii) the purchase of fractional interests in shares of the
Guarantor's capital stock (or the capital stock of a Subsidiary of the
Guarantor) pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (iv) any declaration of a
dividend in connection with any stockholders' rights plan, or the issuance of
rights, stock or other property under any stockholders' rights plan, or the
redemption or repurchase of rights pursuant thereto, (v) 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 and any cash payments in lieu of fractional shares
issued in connection therewith, or (vi) payments under this Guarantee).

         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.

         The right of the Guarantor to participate in any distribution of assets
of any of its Subsidiaries upon any such Subsidiary's liquidation or
reorganization or otherwise is subject to the prior claims of creditors of that
Subsidiary, except to the extent the Guarantor may itself be recognized as a
creditor of that Subsidiary. Accordingly, the Guarantor's obligations under this
Guarantee will be effectively subordinated to all existing and future
liabilities of the Guarantor's Subsidiaries, and claimants should look only to
the assets of the Guarantor for payments hereunder. This Guarantee does not
limit the incurrence or issuance of other secured or unsecured debt of the
Guarantor, including Senior Indebtedness of the Guarantor, under any indenture
that the Guarantor may enter into in the future or otherwise.

                                   TERMINATION

         Section 6.1. Termination.

         This Guarantee shall terminate as to the Capital Securities (i) upon
full payment of the Optional Redemption Price or Special Redemption Price 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 performed or omitted
by 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 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.

                                       14
<PAGE>

         (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 reasonably satisfactory to the
Indemnified Person. Notwithstanding the Guarantor's election to appoint counsel
to represent the Guarantor in an 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 Person(s) 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, 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.

                                       15

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

                                  ARTICLE VIII.

                                  MISCELLANEOUS

         Section 8.1. Successors and Assigns.

         All guarantees and agreements contained in this Guarantee shall bind
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 at least 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 Guarantee Trustee, the Holders of not less than a
Majority in liquidation amount of the Capital Securities and the Guarantor. The
provisions of the Declaration with respect to amendments thereof apply to the
giving of such approval.

         Section 8.3. Notices.

signed by the party giving such notice, and shall be delivered, telecopied or
