          SECTION 2.1. List of Holders.

                                        5
<PAGE>

         The Guarantor shall furnish or cause to be furnished to the Guarantee
Trustee at such times as the Guarantee Trustee may request in writing, within
thirty (30) days after the receipt by the Guarantor of any such request, a list,
in such form as the Guarantee Trustee may reasonably require, of the names and
addresses of the Holders (the "List of Holders") as of a date not more than
fifteen (15) days prior to the time such list is furnished, in each case to the
extent such information is in the possession or control of the Guarantor and is
not identical to a previously supplied list of Holders or has not otherwise been
received by the Guarantee Trustee in its capacity as such. The Guarantee Trustee
may destroy any List of Holders previously given to it on receipt of a new List
of Holders.

          SECTION 2.2. Periodic Reports to the Guarantee Trustee.

         The Guarantor shall deliver to the Guarantee Trustee, within one
hundred and twenty (120) days after the end of each fiscal year of the Guarantor
ending after the date of this Guarantee Agreement, an Officers' Certificate
covering the preceding fiscal year, stating whether or not to the knowledge of
the signers thereof the Guarantor is in default in the performance or observance
of any of the terms or provisions or any of the conditions of this Guarantee
Agreement (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Guarantor shall be in default thereof,
specifying all such defaults and the nature and status thereof of which they
have knowledge.

          SECTION 2.3. Event of Default; Waiver.

         The Holders of a Majority in Liquidation Amount of the Preferred
Securities may, on behalf of the Holders, waive any past Event of Default and
its consequences. Upon such waiver, any such Event of Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
cured, for every purpose of this Guarantee Agreement, but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any
right consequent therefrom.

          SECTION 2.4. Event of Default; Notice.

         (a)      The Guarantee Trustee shall, within ninety (90) days after the
occurrence of a default, transmit to the Holders notices of all defaults
actually known to the Guarantee Trustee, unless such defaults have been cured or
waived before the giving of such notice; provided, that, except in the case of a
default in the payment of a Guarantee Payment, the Guarantee Trustee shall be
protected in withholding such notice if and so long as the Board of Directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Guarantee Trustee in good faith determine that the withholding
of such notice is in the interests of the Holders. For the purpose of this
Section 2.4, the term "default" means any event that is, or after notice or
lapse of time or both would become, an Event of Default.

         (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, or a Responsible Officer charged with the administration of this
Guarantee Agreement shall have obtained written notice, of such Event of Default
from the Guarantor or a Holder.

               POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

          SECTION 3.1. 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 to any Person except a Holder exercising its
rights pursuant to Section 5.4(d) or to a Successor Guarantee Trustee upon
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder, and
such vesting and succession 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 rights, immunities, duties and responsibilities of the
Guarantee Trustee shall be as provided by this Guarantee Agreement and there
shall be no other duties or obligations, express or implied, of the Guarantee
Trustee. Notwithstanding the foregoing, no provisions of this Guarantee
Agreement shall require the Guarantee Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not herein expressly so provided, every provision of this Guarantee
Agreement relating to the conduct or affecting the liability of or affording
protection to the Guarantee Trustee shall be subject to the provisions of this
Section 3.1. To the extent that, at law or in equity, the Guarantee Trustee has
duties and liabilities relating to the Guarantor or the Holders, the Guarantee
Trustee shall not be liable to any Holder for the Guarantee Trustee's good faith
reliance on the provisions of this Guarantee Agreement. The provisions of this
Guarantee Agreement, to the extent that they restrict the duties and liabilities
of the Guarantee Trustee otherwise existing at law or in equity, are agreed by
the Guarantor and the Holders to replace such other duties and liabilities of
the Guarantee Trustee.

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

                  (i)      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; and

                  (ii)     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 Preferred Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the

                                        7

         Guarantee Trustee, or exercising any trust or power conferred upon the
         Guarantee Trustee under this Guarantee Agreement.

          SECTION 3.2. Certain Rights of the 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 in good faith
         and in accordance with the terms hereof 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 reasonably 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 Agreement shall be sufficiently evidenced by an
         Officers' Certificate unless otherwise prescribed herein;

                  (iii)    the Guarantee Trustee may consult with counsel, and
         the advice of such counsel shall be full and complete authorization and
         protection in respect of any action taken, suffered or omitted to be
         taken by it hereunder in good faith and in reliance thereon and in
         accordance with such advice. Such counsel may be counsel to the
         Guarantee Trustee, the Guarantor or any of its Affiliates and may be
         one 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;

                  (iv)     the Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such Holder
         shall have provided to the Guarantee Trustee reasonable security or
         indemnity against the costs, expenses (including reasonable 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, that,
         nothing contained in this Section 3.2(a)(iv) 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; provided, further, that nothing contained in this
         Section 3.2(a)(iv) shall prevent the Guarantee Trustee from exercising
         its rights under Section 4.2 hereof.;

                  (v)      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, and if the Guarantee Trustee
         shall determine to make such inquiry or investigation, it shall be
         entitled to examine the books, records and premises of the Guarantor,
         personally or by agent or attorney;

                                        8
<PAGE>

                  (vi)     the Guarantee Trustee may execute any of the trusts
         or powers hereunder or perform any duties hereunder either directly or
         by or through its agents, attorneys, custodians or nominees and the
         Guarantee Trustee shall not be responsible for any misconduct or
         negligence on the part of any such agent, attorney, custodian or
         nominee appointed with due care by it hereunder;

                  (vii)    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 hereunder,
         the Guarantee Trustee (A) may request instructions from the Holders of
         a Majority in Liquidation Amount of the Preferred Securities, (B) may
         refrain from enforcing such remedy or right or taking such other action
         until such instructions are received and (C) shall be protected in
         acting in accordance with such instructions;

                  (viii)   except as otherwise expressly provided by this
         Guarantee Agreement, the Guarantee Trustee shall not be under any
         obligation to take any action that is discretionary under the
         provisions of this Guarantee Agreement; and

                  (ix)     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 to take
         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 from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

         (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 to act in accordance with such power and
authority.

          SECTION 3.3. Compensation.

         The Guarantor agrees to pay to the Guarantee Trustee from time to time
reasonable compensation for all services rendered by it hereunder (which
compensation shall not be limited by any provisions of law in regard to the
compensation of a trustee of an express trust) and to reimburse the Guarantee
Trustee upon request for all reasonable expenses, disbursements and advances
(including the reasonable fees and expenses of its attorneys and agents)
incurred or made by the Guarantee Trustee in accordance with any provisions of
this Guarantee Agreement.

          SECTION 3.4. Indemnity.

         The Guarantor agrees to indemnify and hold harmless the Guarantee
Trustee and any of its Affiliates and any of their officers, directors,
shareholders, employees, representatives or agents from and against any loss,
damage, liability, tax (other than income, franchise or other taxes imposed on
amounts paid pursuant to Section 3.3), penalty, expense or claim of any kind or

                                       9
<PAGE>

nature whatsoever incurred without negligence, bad faith or willful misconduct
on its part, arising out of or in connection with the acceptance or
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 of its powers or duties hereunder. The Guarantee Trustee
will not claim or exact any lien or charge on any Guarantee Payments as a result
of any amount due to it under this Guarantee Agreement. This indemnity shall
survive the termination of this Agreement or the resignation or removal of the
Guarantee Trustee.

         In no event shall the Guarantee Trustee be liable for any indirect,
special, punitive or consequential loss or damage of any kind whatsoever,
including, but not limited to, lost profits, even if the Guarantee Trustee has
been advised of the likelihood of such loss or damage and regardless of the form
of action.

         In no event shall the Guarantee Trustee be liable for any failure or
delay in the performance of its obligations hereunder because of circumstances
beyond its control, including, but not limited to, acts of God, flood, war
(declared or undeclared), terrorism, fire, riot, embargo, government action,
including any laws, ordinances, regulations, governmental action or the like
which delay, restrict or prohibit the providing of the services contemplated by
this Guarantee Agreement.

          SECTION 3.5. Securities.

         The Guarantee Trustee or any other agent of the Guarantee Trustee, in
its individual or any other capacity, may become the owner or pledgee of Common
or Preferred Securities.

          SECTION 4.1. Guarantee Trustee; Eligibility.

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

                  (ii)     be a corporation organized and doing business under
         the laws of the United States or of any State thereof, authorized to
         exercise corporate trust powers, having a combined capital and surplus
         of at least fifty million dollars ($50,000,000), subject to supervision
         or examination by Federal or State authority and having an office
         within the United States. If such corporation publishes reports of
         condition at least annually, pursuant to law or to the requirements of
         such supervising or examining authority, then, for the purposes of this
         Section 4.1, 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.

                                       10

         (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 shall either eliminate such interest or resign in the manner
and with the effect set out in Section 4.2(c).

          SECTION 4.2. Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a)      Subject to Section 4.2(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 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 hereunder 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 4.2 within thirty (30) days
after delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, 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.

         (a)      The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by or on behalf of the Issuer), as and when due, regardless of
any defense (except for the defense of payment by the Issuer), 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. The Guarantor shall give prompt written notice to the
Guarantee Trustee in the event it makes any direct payment to the Holders
hereunder.

                                       11

         (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 Beneficiaries who have received notice
hereof.

          SECTION 5.2. Waiver of Notice and Demand.

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 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 (other than an extension of
         time for payment of Distributions that results from the extension of
         any interest payment period on the Notes as provided in the Indenture),
         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;

                  (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 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
         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 5.3 that

                                       12
<PAGE>

         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 the
consent of, the Guarantor with respect to the happening of any of the foregoing.

          SECTION 5.4. 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 Guarantee Trustee, the Issuer or any other Person.

          SECTION 5.5. 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 of amounts theretofore paid
by the Issuer) or upon distribution of Notes to Holders as provided in the Trust
Agreement.

          SECTION 5.6. 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 and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, that, the Guarantor
shall not (except to the extent required by mandatory provisions of law) be
entitled to enforce or exercise any rights 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 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 5.7. 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 5.3.

          SECTION 5.8. Enforcement.

                                       13
<PAGE>

         A Beneficiary may enforce the Obligations of the Guarantor contained in
Section 5.1(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.

                                   ARTICLE VI

                           COVENANTS AND SUBORDINATION

          SECTION 6.1. Dividends, Distributions and Payments.

         So long as any Preferred Securities remain outstanding, if there shall
have occurred and be continuing an Event of Default or the Guarantor shall have
entered into an Extension Period as provided for in the Indenture and such
period, or any extension thereof, shall have commenced and be continuing, then
the Guarantor may not (a) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make liquidation payment with respect to, any of
the Guarantor's capital stock or (b) make any payment of principal of or any
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Guarantor that rank pari passu in all respects with or junior
in interest to the Notes (other than (i) repurchases, redemptions or other
acquisitions of shares of capital stock of the Guarantor in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of any one of 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 securities
convertible into or exercisable for such capital stock) as consideration in an
acquisition transaction entered into prior to the occurrence of such Event of
Default or the applicable Extension Period, (ii) as a result of an 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 any class of series of the Guarantor's indebtedness
for any class or series of the Guarantor's capital stock, (iii) the purchase of
fractional interests in shares of the Guarantor's capital stock pursuant to the
conversions or exchange provisions of such capital stock or the security being
converted or exchanged, (iv) any declaration of a dividend in connection with
any rights plan, the issuance of rights, stock or other property under any
rights plan or the redemption or repurchase of rights pursuant thereto, or (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).

          SECTION 6.2. Subordination.

         The obligations of the Guarantor under this Guarantee Agreement will
constitute unsecured obligations of the Guarantor and will rank subordinate and
junior in right of payment to all Senior Debt of the Guarantor.

                                       14
<PAGE>

          SECTION 6.3. Pari Passu Guarantees.

         (a)      The obligations of the Guarantor under this Guarantee
Agreement shall rank pari passu with the obligations of the Guarantor under any
similar guarantee agreements issued by the Guarantor with respect to preferred
securities (if any) similar to the Preferred Securities, issued by trusts other
than the Issuer established or to be established by the Guarantor (if any), in
each case similar to the Issuer.

         (b)      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 thereunder. This Guarantee does not
limit the incurrence or issuance of other secured or unsecured debt of the
