Holders, waive any past Event of Default and its


                                       4

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 2.06. Event of Default; Notice.


            (a) The Guarantee Trustee shall, within 90 days after the occurrence
      of an Event of Default,  transmit by mail, first class postage prepaid, to
      the  Holders,  notices  of all Events of  Default  known to the  Guarantee
      Trustee,  unless such  defaults  have been cured 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  determines  that the
      withholding of such notice is in the interests of the Holders.

            (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 the Trust Agreement shall have obtained  written notice,  of such Event
      of Default.

                        POWERS, DUTIES AND RIGHTS OF THE
                               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 to any Person except a Holder exercising
      his or her rights pursuant to Section 5.04(iv) 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  automatically  vest  in  any
      Successor  Guarantee  Trustee upon acceptance by such Successor  Guarantee
      Trustee of its  appointment  hereunder  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) If an Event of  Default  has  occurred  and is  continuing,  the
      Guarantee  Trustee shall enforce this Guarantee  Agreement for the benefit
      of the Holders.

            (c) The  Guarantee  Trustee,  before 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 shall be
      read into this Guarantee  Agreement against the Guarantee Trustee. In case
      an Event of Default has occurred and is continuing (and 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


                                       5
<PAGE>

      degree  of care and skill in its  exercise  thereof,  as a prudent  person
      would exercise or use in the conduct of his or her own affairs.

            (d) 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;  but in the case
                  of any such  certificates  or opinions  that by any  provision
                  hereof or of the Trust Indenture Act 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 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 to the Guarantee Trustee, or exercising any trust or power
            conferred upon the Guarantee Trustee under this Guarantee Agreement;
            and

                  (iv) no provision of this  Guarantee  Agreement  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  Agreement  or  reasonable
            indemnity  against such risk or liability is not reasonably  assured
            to it.

      Section 3.02. Certain Rights of Guarantee Trustee

      (a) Subject to the provisions of Section 3.01:


                                       6

                  (i)  The  Guarantee  Trustee  may  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  Agreement  shall be  sufficiently  evidenced  by an
            Officers' Certificate unless otherwise prescribed herein.

                  (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
            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.

                  (iv) The Guarantee Trustee may consult with legal counsel, and
            the  written  advice or  Opinion of  Counsel  with  respect to legal

            respect of any action  taken,  suffered or omitted to be taken by it
            hereunder  in good  faith  and in  accordance  with  such  advice or
            opinion. Such legal counsel may be legal counsel to 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.

                  (v) 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 such reasonable
            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;  provided  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
            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.

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

            by or through its agents or  attorneys,  and the  Guarantee  Trustee
            shall not be  responsible  for any  misconduct  or negligence on the

                  (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
            are  received,  and (C) shall be protected  in acting in  accordance
            with 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

      duty to act in accordance with such power and authority.

      Section 3.03.  Indemnity.  The Guarantor agrees to indemnify the Guarantee
Trustee for,  and to hold it harmless  against,  any loss,  liability or expense
incurred without  negligence or willful  misconduct on the part of the Guarantee

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.

      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  Person  that is  eligible  pursuant  to the  Trust
            Indenture Act to act as such and has a combined  capital and surplus
            of at least fifty million U.S. dollars ($50,000,000), and shall be a
            corporation  meeting the requirements of Section 310(a) of the Trust
            Indenture Act. If such corporation publishes reports of condition at
            least  annually,  pursuant  to  law or to  the  requirements  of the
            supervising or examining  authority,  then, for the purposes of this
            Section and to the extent  permitted by the Trust Indenture Act, 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 4.01(a),  the Guarantee  Trustee shall immediately
      resign in the manner and with the effect set out in Section 4.02(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


                                       8
<PAGE>

      shall in all respects  comply with the provisions of Section 310(b) of the
      Trust  Indenture Act. In determining  whether the Guarantee  Trustee has a
      "conflicting  interest"  within the  meaning of Section  310(b)(1)  of the
      Trust  Indenture Act, the  provisions  contained in the proviso to Section
      310(b)(1) of the Trust Indenture Act and the Guarantee Trustee's Statement
      of Eligibility on Form T-1 shall be deemed incorporated herein.

      Section  4.02.  Appointment,  Removal  and  Resignation  of the  Guarantee
Trustee.

            (a)  Subject  to  Section  4.02(b),  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 new,  eligible
      guarantee trustee has been appointed (a "Successor Guarantee Trustee") and
      has  accepted  such  appointment  and assumed the  applicable  obligations
      hereunder  by written  instrument  executed  by such  Successor  Guarantee
      Trustee and delivered to the Guarantor.

            (c) 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 4.02 within 60 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.

      Section 5.01.  Guarantee.  The Guarantor  irrevocably and  unconditionally
agrees to pay in full to the Holders of the Outstanding Preferred Securities the
Guarantee  Payments  (without  duplication of amounts  theretofore paid by or on
behalf  of the  Issuer  pursuant  to the  Trust  Agreement  or by the  Guarantor
pursuant to the Indenture), 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.

      Section 5.02.  Waiver of Notice and Demand.  The  Guarantor  hereby waives
notice of acceptance of the Guarantee Agreement and of any liability to which it
applies or may apply,  presentment,  demand for payment,  any right to require a
proceeding first against the Guarantee  Trustee,  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  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 an  Extension  Period on the
      Debentures as so 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,  termination,  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 detect or  deficiency  in, the Preferred
      Securities;

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

            (g)  to  the  extent  permitted  by  law,  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.

      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 5.04. Rights of Holders The Guarantor expressly acknowledges that:
(i) this Guarantee  Agreement will be deposited with the Guarantee Trustee to be
held for the benefit of the Holders; (ii) the Guarantee Trustee has the right to
enforce this Guarantee Agreement on behalf of the Holders;  (iii) 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
exercise  or  direct  the  exercise  of any  trust or power  conferred  upon the
Guarantee  Trustee  under this  Guarantee  Agreement;  and (iv) if the Guarantee
Trustee has failed to enforce this Guarantee  Agreement as above  provided,  any
Holder may  institute  a legal


                                       10
<PAGE>

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 5.05.  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 of amounts  theretofore paid by the Issuer) or upon  distribution of
Debentures to Holders as provided in the Trust Agreement.

      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 and shall have the
right to waive  payment  by the  Issuer  pursuant  to  Section  5.01;  provided,
however,  that the  Guarantor  shall  not  (except  to the  extent  required  by

                          COVENANTS AND SUBORDINATION


      Section  6.01.  Ranking.  This  Guarantee  Agreement  will  constitute  an
unsecured  obligation of the Guarantor and will rank (i)  subordinate and junior
in right of payment to all other liabilities of the Guarantor, except those made
pari passu or subordinate  by their terms,  (ii) 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 (iii) senior
to the Guarantor's Common Securities.

      Section  6.02.  Limitation  of  Transactions.  So  long  as any  Preferred
Securities  remain  outstanding,  if (i) there  shall have  occurred an Event of
Default,  (ii) there shall have occurred an event of default under the Indenture
or (iii) the Guarantor has  exercised its option to defer  interest  payments on
the Debentures by extending the interest payment period as provided therein, and
such period or extension  thereof  shall be  continuing,  then (a) the Guarantor
shall not declare or pay any dividend on, make any distribution or other payment
with respect to, or redeem,  purchase,  acquire or make any liquidation  payment
with  respect  to  any  of  its  capital  stock  (other  than  (1)  repurchases,
redemptions or other acquisitions of shares of the Guarantor's  capital stock in
connection with the  satisfaction by the Guarantor of its obligations  under any
employee  benefit  plans,  (2) as a result of an exchange or  conversion  of one
class or series of the Guarantor's  capital stock for another class or series of
the

Guarantor's capital stock or (3) the purchase of fractional  interests in shares
of the  Guarantor's  capital  stock  pursuant  to  the  conversion  or  exchange
provisions of such capital stock or the security being  converted or exchanged),
(b) the Guarantor shall not make any payment of interest,  principal or premium,
if any,  on or repay,  repurchase  or redeem any debt  securities  issued by the
Guarantor  that rank pari  passu  with or junior to the  Debentures  and (c) the
Guarantor  shall not make any  guarantee  payments with respect to the foregoing
(other than pursuant to this Guarantee Agreement).

      In addition,  so long as any Preferred Securities remain outstanding,  the
Guarantor  (i)  will  remain  the  sole  direct  or  indirect  owner  of all the
outstanding  Common  Securities;  provided that any  permitted  successor of the
Guarantor  under the Indenture may succeed to the  Guarantor's  ownership of the
Common Securities, (ii) will not take any action which would cause the Issuer to
cease to be treated  as a grantor  trust for United  States  federal  income tax
purposes and (iii) will cause the Issuer to remain a statutory  business  trust,
except in connection with a distribution  of the  Debentures,  the redemption of
all of the Trust Securities or mergers, consolidations or amalgamations, each as
provided in the Trust Agreement.

                                  ARTICLE VII
                                  TERMINATION

      Section 7.01. Termination. This Guarantee Agreement shall terminate and be
of no  further  force and  effect  upon (i) full  payment  by the  Issuer or the
Guarantor,  as the  case  may be,  of the  Redemption  Price  for all  Preferred
Securities, (ii) the distribution of the Debentures to the Holders in accordance
with Article VIII of the Trust  Agreement upon the  dissolution of the Issuer or
(iii) full  payment by the Issuer or the  Guarantor,  as the case may be, of the
amounts  payable in accordance  with the Trust Agreement upon the dissolution 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 Preferred
Securities or this Guarantee Agreement.

                                  ARTICLE VIII
                                 MISCELLANEOUS

      Section  8.01.  Successors  and Assigns.  All  guarantees  and  agreements
contained  in this  Guarantee  Agreement  shall  bind the  successors,  assigns,
receivers,  trustees and representatives of the Guarantor and shall inure to the
benefit  of the  Holders  of the  Preferred  Securities  then  outstanding.  The
Guarantor  may not  consolidate  with or merge  with or into,  or sell,  convey,
transfer or lease its properties and assets as an entirety or  substantially  as
an entirety  (either in one  transaction  or a series of  transactions)  to, any
Person unless permitted under Article Five of the Indenture.  In connection with
