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
Securities.

         (b) The Guarantee Trustee shall not be deemed to have knowledge of any
Guarantee Event of Default unless the Guarantee Trustee shall have received
written notice thereof or a Responsible Officer of the Guarantee Trustee charged
with the administration of the Declaration shall have obtained actual knowledge
thereof.

         Section 2.8 CONFLICTING INTERESTS. The Declaration shall be deemed to
be specifically described in this Guarantee for the purposes of clause (i) of
the first proviso contained in Section 310(b) of the Trust Indenture Act.

to the names and addresses of the Holders of the Securities in accordance with
Section 312 of the Trust Indenture Act, regardless of the source from which such
information was derived, shall not be deemed to be a violation of any existing
law, or any law hereafter enacted which does not specifically refer to Section
312 of the Trust Indenture Act, nor shall the Guarantee Trustee be held
accountable by reason of mailing any material pursuant to a request made under
Section 312(b) of the Trust Indenture Act.

         Section 2.10 GUARANTEE TRUSTEE MAY FILE PROOFS OF CLAIM. Upon the
occurrence of a Guarantee Event of Default, the Guarantee Trustee is hereby
authorized to (a) recover judgment, in its own name and as trustee of an express
trust, against the Guarantor for the whole amount of any Guarantee Payments
remaining unpaid and (b) file such proofs of claim


                                      -6-


and other papers or documents as may be necessary or advisable in order to

judicial proceedings relative to the Guarantor, its creditors or its property.

                                  ARTICLE III.

                 POWERS, DUTIES AND RIGHTS OF GUARANTEE TRUSTEE

         Section 3.1 POWERS AND DUTIES OF GUARANTEE TRUSTEE

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

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

         (c) The Guarantee Trustee, before the occurrence of any Guarantee Event
of Default and after the curing of all Guarantee Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Guarantee, and no implied covenants shall be read into this
Guarantee against the Guarantee Trustee. In case a Guarantee Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6) and is
actually known to a Responsible Officer of the Guarantee Trustee, the Guarantee
Trustee shall exercise such of the rights and powers vested in it by this
Guarantee, and use the same degree of care and skill in its exercise thereof, as
a prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

         (d) No provision of this Guarantee shall be construed to relieve the
Guarantee Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

                  (i) prior to the occurrence of any Guarantee Event of Default
and after the curing or waiving of all such Guarantee Events of Default that may
have occurred:

                           (A) the duties and obligations of the Guarantee
Trustee shall be determined solely by the express provisions of this Guarantee,
and the Guarantee Trustee shall not be liable except for the performance of such
duties and obligations as are specifically set


                                      -7-


forth in this Guarantee, and no implied covenants or obligations shall be
read into this Guarantee against the Guarantee Trustee; and

                           (B) in the absence of bad faith on the part of the
Guarantee Trustee, the Guarantee Trustee may conclusively rely, as to the truth
of the statements and the correctness of the opinions expressed therein, upon
any certificates or opinions furnished to the Guarantee Trustee and conforming
to the requirements of this Guarantee; but in the case of any such certificates
or opinions that by any provision hereof are specifically required to be
furnished to the Guarantee Trustee, the Guarantee Trustee shall be under a duty
to examine the same to determine whether or not they conform to the requirements
of this Guarantee;

                  (ii) the Guarantee Trustee shall not be liable for any error
of judgment made in good faith by a Responsible Officer of the Guarantee
Trustee, unless it shall be proved that the Guarantee Trustee was negligent in
ascertaining the pertinent facts upon which such judgment was made;

                  (iii) the Guarantee Trustee shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance
with the direction of the Holders of not less than a Majority in Liquidation
Amount of the Securities relating to the time, method and place of conducting
any proceeding for any remedy available to the Guarantee Trustee, or exercising
any trust or power conferred upon the Guarantee Trustee under this Guarantee;
and

                  (iv) no provision of this Guarantee shall require the
Guarantee Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if the Guarantee Trustee shall have reasonable
grounds for believing that the repayment of such funds or liability is not
reasonably assured to it under the terms of this Guarantee or if the Guarantee
Trustee shall have reasonable grounds for believing that an indemnity,
reasonably satisfactory to the Guarantee Trustee, against such risk or liability
is not reasonably assured to it under the terms of this Guarantee.

         Section 3.2 CERTAIN RIGHTS OF GUARANTEE TRUSTEE.

         (a) Subject to the provisions of Section 3.1:

                  (i) The Guarantee Trustee may conclusively rely, and shall be
fully protected in acting or refraining from acting upon, any resolution,

consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed, sent or
presented by the proper party or parties;

                  (ii) Any direction or act of the Guarantor contemplated by
this Guarantee shall be sufficiently evidenced by an Officers' Certificate;

before taking, suffering or omitting


                                      -8-


any action hereunder, the Guarantee Trustee (unless other evidence is herein
specifically prescribed) may, in the absence of bad faith on its part,
request and conclusively rely upon an Officers' Certificate which, upon
receipt of such request, shall be promptly delivered by the Guarantor;

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

                  (v) The Guarantee Trustee may consult with counsel, and the
advice or opinion of such counsel with respect to legal matters shall be full
and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in accordance with such

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

                  (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, and the signature of the Guarantee Trustee or
its agents alone shall be sufficient and effective to perform any such action.
No third party shall be required to inquire as to the authority of the Guarantee
Trustee to so act or as to its compliance with any of the terms and provisions
of this Guarantee, both of which shall be conclusively evidenced by the
Guarantee Trustee's or its agent's taking such action; and

                                      -9-


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

         (b) No provision of this Guarantee shall be deemed to impose any duty
or obligation on the Guarantee Trustee to perform any act or acts or exercise
any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty.

         Section 3.3 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE. The
recitals contained in this Guarantee shall be taken as the statements of the
Guarantor, and the Guarantee Trustee does not assume any responsibility for
their correctness. The Guarantee Trustee makes no representations as to the

                                GUARANTEE TRUSTEE

         Section 4.1 GUARANTEE TRUSTEE; ELIGIBILITY.

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

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

              (ii) be a corporation organized and doing business under the laws
of the United States of America or any state or territory thereof or of the
District of Columbia, or a corporation or other Person permitted by the
Securities and Exchange Commission to act as an institutional trustee under the
Trust Indenture Act, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least 50 million U.S.
dollars ($50,000,000), and subject to supervision or examination by federal,
state, territorial or District of Columbia authority. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of the supervising or examining authority referred to above, then,
for the purposes of this Section 4.1(a)(ii), the combined capital and surplus of
such corporation shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to
so act under Section 4.1(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.2(c).


                                     -10-


         (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 4.2 APPOINTMENT, REMOVAL AND RESIGNATION OF GUARANTEE TRUSTEE.

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

         (b) The Guarantee Trustee shall not be removed in accordance with
Section 4.2(a) until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by written instrument executed by such Successor
Guarantee Trustee and delivered to the Guarantor.

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

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of removal or resignation, the
removed or resigning Guarantee Trustee may petition any court of competent
jurisdiction for appointment of a Successor Guarantee Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper, appoint
a Successor Guarantee Trustee.

         (e) No Guarantee Trustee shall be liable for the acts or omissions to
act of any Successor Guarantee Trustee.

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

                                    ARTICLE V.

                                    GUARANTEE

         Section 5.1 GUARANTEE. The Guarantor irrevocably and unconditionally
agrees to pay in full to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by the Trust), as and when due, regardless of any
defense, right of set-off or counterclaim


                                     -11-


that the Trust may have or assert. The Guarantor's obligation to make a
Guarantee Payment may be satisfied by direct payment of the required amounts
by the Guarantor to the Holders or by causing the Trust to pay such amounts
to the Holders. Notwithstanding anything to the contrary herein, the
Guarantor retains all of its rights under the Indenture to extend the
interest payment period on the Debentures and the Guarantor shall not be
obligated hereunder to make any Guarantee Payments during any Extended
Interest Payment Period (as defined in the certificate evidencing the
Debentures) with respect to the Distributions (as defined in the Declaration)
on the Securities.

         Section 5.2 WAIVER OF NOTICE AND DEMAND. The Guarantor hereby waives
notice of acceptance of this Guarantee and of any liability to which it applies
or may apply, presentment, demand for payment, any right to require a proceeding
first against the Trust or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

         Section 5.3 OBLIGATIONS NOT AFFECTED. The obligations, covenants,
agreements and duties of the Guarantor under this Guarantee shall be absolute
and unconditional and shall remain in full force and effect until the entire
liquidation amount of all outstanding Securities shall have been paid and such
obligation shall in no way be affected or impaired by reason of the happening
from time to time of any event, including without limitation, the following,
whether or not with notice to, or the consent of, the Guarantor:

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

         (b) The extension of time for the payment by the Trust of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Securities or the extension of time
for the performance of any other obligation under, arising out of, or in
connection with the Securities (other than an extension of time for payment of
Distributions, Redemption Price, Liquidation Distribution or other sum payable
that results from the extension of any interest payment period on the Debentures
or any change to the maturity date of the Debentures permitted by the
Indenture);

         (c) Any failure, omission, delay or lack of diligence on the part of
the Property Trustee or the Holders to enforce, assert or exercise any right,
privilege, power or remedy conferred on the Property Trustee or the Holders
pursuant to the terms of the Securities, or any action on the part of the Trust
granting indulgence or extension of any kind;

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

         (e) Any invalidity of, or defect or deficiency in, the Securities;


                                     -12-


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

         (g) Any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

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

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

         Section 5.4 RIGHTS OF HOLDERS.

         (a) The Holders of at least a Majority in Liquidation Amount of the
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of this
Guarantee or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under this Guarantee.

         (b) If the Guarantee Trustee fails to enforce this Guarantee, then any
Holder of Securities may, subject to the subordination provisions of Section
6.2, institute a legal proceeding directly against the Guarantor to enforce the
Guarantee Trustee's rights under this Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. In addition, if the Guarantor has failed to make a Guarantee Payment, a
Holder of Securities may, subject to the subordination provisions of Section
6.2, directly institute a proceeding against the Guarantor for enforcement of
the Guarantee for such payment to the Holder of the Securities of the principal
of or interest on the Debentures on or after the respective due dates specified
in the Debentures, and the amount of the payment will be based on the Holder's
pro rata share of the amount due and owing on all of the Securities. The
Guarantor hereby waives any right or remedy to require that any action on this
Guarantee be brought first against the Trust or any other person or entity
before proceeding directly against the Guarantor.

         Section 5.5 GUARANTEE OF PAYMENT. This Guarantee creates a guarantee of
payment and not of collection.


                                     -13-


         Section 5.6 SUBROGATION. The Guarantor shall be subrogated to all (if
any) rights of the Holders of Securities against the Trust in respect of any
amounts paid to such Holders by the Guarantor under this Guarantee; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Guarantee, if at the
time of any such payment, any amounts are due and unpaid under this Guarantee.
If any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Guarantee Trustee for the benefit of the Holders.

         Section 5.7 INDEPENDENT OBLIGATIONS. The Guarantor acknowledges that
its obligations hereunder are independent of the obligations of the Trust with
respect to the Securities, and that the Guarantor shall be liable as principal
and as debtor hereunder to make Guarantee Payments pursuant to the terms of this
Guarantee notwithstanding the occurrence of any event referred to in subsections
5.3(a) through 5.3(g), inclusive, hereof.


                                  ARTICLE VI.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

         Section 6.1 LIMITATION OF TRANSACTION. So long as any Securities remain
outstanding, if (a) there shall have occurred an event of default under the
Indenture with respect to the Debentures, (b) there shall be a Guarantee Event
of Default or (c) the Guarantor shall have given notice of its election of an
Extended Interest Payment Period as provided in the certificate evidencing the
Debentures and shall not have rescinded such notice, or such Extended Interest
Payment Period or any extension thereof shall be continuing, then Guarantor
shall not, and shall not permit any subsidiary of the Guarantor, to (x) declare
or pay any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to any of the Guarantor's capital stock or (y)
make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Guarantor that rank on a parity
with or junior in interest to the Debentures or make any guarantee payments with
respect to any guarantee by the Guarantor of the debt securities of any
subsidiary of the Guarantor if such guarantee ranks on a parity with or junior
in interest to the Debentures (other than (i) dividends or distributions in
common stock of the Guarantor, (ii) payments under this Guarantee and (iii) any
declaration of a dividend in connection with the implementation of a
shareholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, and
(iv) purchases of common stock related to the issuance of common stock or rights
under any of the Guarantor's benefit plans).

         Section 6.2 RANKING. This Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (a) subordinate and junior in right of
payment to all other liabilities of the Guarantor, (b) on a parity 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 securities of any Affiliate of the Guarantor and (c) senior to
the


                                     -14-


Guarantor's common stock. In addition, at all times such obligations will be
structurally subordinated to the liabilities and obligations of the
Guarantor's subsidiaries.

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

                                   ARTICLE VII.

                                   TERMINATION

         Section 7.1 TERMINATION. This Guarantee shall terminate upon (a) full
payment of the Redemption Price of all Securities, (b) distribution of the
Debentures to the Holders of all the Securities or (c) full payment of the
amounts payable in accordance with the Declaration upon liquidation of the
Trust. Notwithstanding the foregoing, this Guarantee will continue to be
effective or will be reinstated, as the case may be, if at any time any Holder
of Securities must restore payment of any sums paid under the Securities or
under this Guarantee.


                                  ARTICLE VIII.

         Section 8.1 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, liability, expense 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 Guarantor and upon such information, opinions,
reports or statements presented to 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 has been selected with reasonable care
by or on behalf of the Guarantor, 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 Securities might properly be paid.

         Section 8.2 INDEMNIFICATION. The Guarantor agrees to indemnify each
Indemnified Person for, and to hold each Indemnified Person harmless against any
loss, liability


                                     -15-


or expense incurred without negligence or bad faith on its part, arising out
of or in connection with the acceptance or administration of the trust or
trusts hereunder, including the costs and expenses (including reasonable
legal fees and expenses) of defending itself against, or investigating, any
claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder. The obligation to indemnify as set forth in
this Section 8.2 shall survive the termination of this Guarantee.

                                  ARTICLE IX.

materially adversely affect the rights of the Holders (in which case no consent
of the Holders will be required), this Guarantee may not be amended without the
prior approval of the Holders of not less than 66-2/3% of the aggregate
liquidation amount of the Securities. The provisions of Section 11.2 of the
Declaration with respect to meetings of, and action by written consent of, the
