                                  ARTICLE III

                POWERS, DUTIES AND RIGHTS OF GUARANTEE TRUSTEE

          SECTION 3.01 POWERS AND DUTIES OF THE GUARANTEE TRUSTEE.

          (a)  This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement or any rights hereunder to any Person except a Holder
exercising his or her rights pursuant to Section 5.04 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 vest automatically in any Successor
Guarantee Trustee, and such vesting and cessation of title shall be effective
whether or not conveyancing documents have been executed and delivered pursuant
to the appointment of such Successor Guarantee Trustee.

          (b)  The Guarantee Trustee, prior to the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants or obligations shall be read
into this Guarantee Agreement against the Guarantee Trustee.  In case an Event
of Default has occurred (that has not been cured or waived pursuant to Section
2.06), the Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Guarantee Agreement, and use the same degree of care and skill in
its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

          (c)  No provision of this Guarantee Agreement 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 such 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 Agreement, 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
                 Agreement; 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 Agreement; 

                                      -6-

 
                 provided, however, that 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
                 Agreement;

                 (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 or such Responsible Officer 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 a Majority in
          liquidation amount of the Preferred Securities relating to the time,
          method and place of conducting any proceeding for any remedy available

                 (iv)    no provision of this Guarantee Agreement shall require

          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 or liability is not reasonably assured to it
          under the terms of this Guarantee Agreement or adequate indemnity
          against such risk or liability is not reasonably assured to it.

                 (iii)   whenever, in the administration of this Guarantee
          Agreement, 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 rely upon an Officers' Certificate which, upon
          receipt of such request, shall be promptly delivered by the Guarantor;

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

                 (v)     the Guarantee Trustee shall be under no obligation to

          security and indemnity as would satisfy a reasonable person in the
          position of the Guarantee Trustee, against the costs, expenses
          (including attorneys' fees and expenses) and liabilities that might be
          incurred by it in complying with such request or direction, including
          such reasonable advances as may be requested by the Guarantee Trustee;
          provided, however, that nothing contained in this Section 3.02(a)(v)
          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 Agreement;

                 (vi)    the Guarantee Trustee shall not be bound to make any

          certificate, statement, instrument, opinion, report, notice, request,
          direction, consent, order, bond, debenture, note, other evidence of
          indebtedness or other paper or document reasonably believed by it to
          be genuine, but the Guarantee Trustee, in its discretion, may make
          such further inquiry or investigation into such facts or matters as it
          may see fit;

                 (vii)   the Guarantee Trustee may execute any of the trusts or

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


                                      -8-

 
                 (viii)  whenever in the administration of this Guarantee
          Agreement 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, (B) may refrain from enforcing such
          remedy or right or taking such other action until such instructions

          (b)  No provision of this Guarantee Agreement 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.

                               GUARANTEE TRUSTEE

          SECTION 4.01 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
          laws of the United States of America or any State or Territory thereof
          or of the District of Columbia, or a corporation or Person permitted
          by the Securities and Exchange Commission to act as an institutional
          trustee under the Trust Indenture Act, authorized under such laws to
          exercise corporate trust powers, having a combined capital and surplus
          of at least 50 million U.S. dollars ($50,000,000), and subject to
          supervision or examination by Federal, State, Territorial or District
          of Columbia authority.  If such corporation publishes reports of
          condition at least annually, pursuant to law or to the requirements of
          the supervising or examining authority referred to above, then, for
          the purposes of this Section 4.01(a)(ii), the combined capital and
          surplus of such

                                      -9-

 
          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 4.01(a), the Guarantee Trustee shall immediately resign
in the manner and with the effect set out in Section 4.03(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.

          SECTION 4.02 COMPENSATION AND REIMBURSEMENT.

          The Guarantor agrees:

          (a)  to pay the Guarantee Trustee from time to time such reasonable
compensation as the Guarantor and the Guarantee Trustee shall from time to time
agree in writing for all services rendered by it hereunder (which compensation
shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust);

          (b)  except as otherwise expressly provided herein, to reimburse the
Guarantee Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Guarantee Trustee in accordance with the
provisions of this Guarantee (including the reasonable compensation and expenses
of its agents and counsel), except any such expense, disbursement or advance as
may be attributable to its negligence or bad faith; and

          (c)  to indemnify each of the Guarantee Trustee and any predecessor
Guarantee Trustee for, and to hold it harmless from and against, any and all
loss, damage, claim, liability or expense, including taxes (other than taxes
based upon the income of the Guarantee Trustee) incurred without negligence or
bad faith on its part, arising out of or in connection with the acceptance of
the administration of this Guarantee Agreement, including the costs and expenses
of defending itself against any claim or liability in connection with the
exercise or performance of any its powers or duties hereunder.

          As security for the performance of the obligations of the Guarantor
under this Section, the Guarantee Trustee shall have a lien prior to the
Preferred Securities upon all the property and funds held or collected by the
Guarantee Trustee as such, except funds held in trust for the payment of
principal of, and premium (if any) or interest on, particular obligations of the
Guarantor under this Guarantee Agreement.

          The provisions of this Section shall survive the termination of this
Guarantee Agreement.

                                     -10-

 
          SECTION 4.03 APPOINTMENT, REMOVAL AND RESIGNATION OF GUARANTEE
TRUSTEE.

          (a)  Subject to Section 4.03(b), unless an Event of Default shall have
occurred and be continuing, the Guarantee Trustee may be appointed or removed
without cause at any time by the Guarantor.

          (b)  The Guarantee Trustee shall not be removed 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 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 4.03 within 60 days after
delivery to the Guarantor of an instrument of resignation, the 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)  The Guarantor shall give notice of each resignation and each
removal of the Guarantee Trustee and each appointment of a successor Guarantee
Trustee to all Holders in the manner provided in Section 8.03 hereof.  Each
notice shall include the name of the successor Guarantee Trustee and the address
of its Corporate Trust Office.

                                   GUARANTEE

          SECTION 5.01 GUARANTEE.  The Guarantor irrevocably and
unconditionally agrees to pay in full to the Holders the Guarantee Payments
(without duplication of amounts theretofore paid by the Issuer), as and when
due, regardless of any defense, right of set-off or counterclaim which 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.

                                     -11-

 
          SECTION 5.02 WAIVER OF NOTICE AND DEMAND.  The Guarantor hereby

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 5.03 OBLIGATIONS NOT AFFECTED.  The obligation of the
Guarantor to make the Guarantee Payments under this Guarantee Agreement shall in
no way be affected or impaired by reason of the happening from time to time of
any of the following:

          (a)  the release or waiver, by operation of law or otherwise, of the
     performance or observance by the Issuer of any express or implied
     agreement, covenant, term or condition relating to the Preferred 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, Liquidation Distribution or
     any other sums payable under the terms of the Preferred Securities or the
     extension of time for the performance of any other obligation under,
     arising out of, or in connection with, the Preferred Securities (other than
     an extension of time for payment of Distributions, Redemption Price,
     Liquidation Distribution or other sum payable that results from the
     extension of any interest payment period on the 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 Preferred
     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

     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 Preferred
     Securities;

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

          (g)  any other circumstance whatsoever that might otherwise constitute
     a legal or equitable discharge or defense of a guarantor, it being the
     intent of this Section 5.03 that the obligations of the Guarantor hereunder
     shall be absolute and unconditional under any and all circumstances.


                                     -12-

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

          SECTION 5.04 RIGHTS OF HOLDERS.  The Guarantor expressly acknowledges
that: (a) this Guarantee Agreement will be deposited with the Guarantee Trustee
to be held for the benefit of the Holders; (b) the Guarantee Trustee has the
right to enforce this Guarantee Agreement on behalf of the Holders; (c) the
Holders of a Majority in liquidation amount of the Preferred Securities have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Guarantee Trustee in respect of this Guarantee Agreement
or exercising any trust or power conferred upon the Guarantee Trustee under this
Guarantee Agreement; and (d) any Holder may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Guarantee
Agreement without first instituting a legal proceeding against the Issuer or any
other person or entity.

          SECTION 5.05 GUARANTEE OF PAYMENT.  This Guarantee Agreement creates
a guarantee of payment and not of collection.  This Guarantee Agreement will not
be discharged except by payment of the Guarantee Payments in full (without
duplication).

          SECTION 5.06 SUBROGATION.  The Guarantor shall be subrogated to all
(if any) rights of the Holders against the Issuer in respect of any amounts paid
to the Holders by the Guarantor under this Guarantee Agreement; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any rights which
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Guarantee Agreement,
if, at the time of any such payment, any amounts of Guarantee Payments are due
and unpaid under this Guarantee Agreement.  If any amount shall be paid to the
Guarantor in violation of the preceding sentence, the Guarantor agrees to hold
such amount in trust for the Holders and to pay over such amount to the Holders.

          SECTION 5.07 INDEPENDENT OBLIGATIONS.  The Guarantor acknowledges
that its obligations hereunder are independent of the obligations of the Issuer
with respect to the Preferred Securities and that the Guarantor shall be liable
as principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.03.

                                 SUBORDINATION

          SECTION 6.01 SUBORDINATION.  This Guarantee Agreement will constitute
an unsecured obligation of the Guarantor and will rank (a) subordinate and
junior in right of payment to all other liabilities of the Guarantor, including
the Debentures, except those made

                                     -13-

 
pari passu or subordinate by their terms, (b) pari passu with the most senior
preferred or preference stock now or hereafter issued by the Guarantor and with
any guarantee now or hereafter entered into by the Guarantor in respect of any
preferred or preference stock of any Affiliate of the Guarantor, and (c) senior
to all common stock of the Guarantor.  Nothing in this Section 6.01 shall apply
to claims of, or payments to, the Guarantee Trustee under or pursuant to Section
4.02 hereof.


                                  ARTICLE VII

                                  TERMINATION

          SECTION 7.01 TERMINATION.  This Guarantee Agreement shall terminate
and be of no further force and effect upon:  (a) full payment of the Redemption
Price of all Preferred Securities, and all accrued and unpaid Distributions to
the date of redemption, (b) the distribution of Debentures to Holders in
exchange for all of the Preferred Securities or (c) full payment of the amounts
payable in accordance with the Trust Agreement upon liquidation of the Issuer.
Notwithstanding the foregoing, this Guarantee Agreement will continue to be
effective or will be reinstated, as the case may be, if at any time any Holder
must restore payment of any sums paid with respect to the Preferred Securities
or under this Guarantee Agreement.


                                 ARTICLE VIII
