existing law, or any law hereafter enacted which does not specifically refer to

                                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
                                        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, certificate, statement, instrument,
                  opinion, report, notice, request, direction, consent, order,
                  bond, debenture, note, other evidence of indebtedness or other
                  paper or document believed by it to be genuine and to have
                  been signed, sent or presented by the proper party or parties;

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

                           (iii) Whenever, in the administration of this
                  Guarantee, the Guarantee Trustee shall deem it desirable that
                  a matter be proved or established before taking, suffering or
                  omitting any action hereunder, the Guarantee Trustee (unless
                  other evidence is herein specifically prescribed) may, in the
                  absence of bad faith on its part, request and conclusively
                  rely upon an Officers' Certificate which, upon receipt of such
                  request, shall be promptly delivered by the Guarantor;

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

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

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

                           (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 to act in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty.

                  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

                  condition so published.

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

                  (c) If the Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply
with the provisions of Section 310(b) of the Trust Indenture Act.

         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.

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

full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Trust), as and when due, regardless of any defense,
right of set-off or counterclaim that the Trust may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Trust to pay such amounts to the Holders. Notwithstanding anything to the
contrary herein, the Guarantor retains all of its rights under the Indenture to
extend the interest payment period on the Debentures pursuant to Section 3.11
thereof and the Guarantor shall not be obligated hereunder to make any Guarantee
Payments during any Extension Period (as defined in the certificate evidencing
the Debentures) with respect to the Distributions (as defined in the Trust
Agreement) 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);

                  (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;

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

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

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

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

         SECTION 5.4. Rights of Holders.

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

                  (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.

         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.

Debentures, (ii) there shall be a Guarantee Event of Default or (iii) the
Guarantor shall have given notice of its election of an Extension Period as
provided in the certificate evidencing the Debentures and shall not have
rescinded such notice, or such Extension Period or any extension thereof shall
be continuing, then the 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 pari passu 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
pari passu with or junior in interest to the Debentures (other than (a)
dividends or distributions in Common Stock of the Guarantor, (b) any declaration
of a dividend in connection with the implementation of a rights plan or the
issuance of stock under any such plan or the redemption or repurchase of any
such rights pursuant thereto, (c) payments under this Guarantee and (d)
purchases of Common Stock related to the issuance of Common Stock or rights
under any of the Company's benefits plans for its directors, officers or
employees).

         SECTION 6.2. Ranking.

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

         SECTION 6.3. Subordination of Common Securities.

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

                                   ARTICLE 7

                                   TERMINATION

         SECTION 7.1. Termination.

                  This Guarantee shall terminate upon (i) full payment of the
Redemption Price of all Securities, (ii) distribution of the Debentures to the
Holders of all the Securities or (iii) full payment of the amounts payable in
accordance with the Trust Agreement 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.

and to hold each Indemnified Person harmless against any loss, liability 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 reasonable costs 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 provisions
of this Section 8.1 shall survive the termination of this Guarantee or the
resignation or removal of the Guarantee Trustee.

                                   ARTICLE 9

                                  MISCELLANEOUS

         SECTION 9.1. Successors and Assigns.

involving the Guarantor that is permitted under Article VIII of the Indenture
and pursuant to which the successor or assignee agrees in writing to perform the
Guarantor's obligations hereunder, the Guarantor shall not assign its
obligations hereunder.

         SECTION 9.2. Amendments.

                  Except with respect to any changes that do not 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 at least a Majority in Liquidation Amount of the
Securities. The provisions of Section 11.2 of the Trust Agreement with respect
