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.

Guarantee Trustee from liability for its own negligent action, its own negligent

                Trustee shall be  determined  solely by the  express  provisions
                of this Guarantee, and the Guarantee Trustee shall not be liable

                Guarantee Trustee, the Guarantee Trustee may conclusively  rely,
                as to the truth  of the  statements and the  correctness  of the

                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

                this Guarantee;
<PAGE>

                (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 such  Responsible
         Officer of the Guarantee Trustee or 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 written  direction of the Holders of not less than
         a Majority  in liquidation amount of the Capital Securities relating to
         the  time, method and place of conducting any proceeding for any remedy
         available to  the Guarantee Trustee, or relating to the exercise of 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 is not  reasonably  assured  to it  under  the  terms  of
         this Guarantee or security and indemnity,  reasonably  satisfactory  to
         the Guarantee Trustee, against such risk or liability is not reasonably
         assured to it.

         Guarantee.

         (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

                       -------------------------

         (a)    An Event of Default under this  Guarantee  will  occur  upon the
failure of the  Guarantor  to perform  any of its  payment or other  obligations

         (b)    The Holders of a Majority in liquidation  amount of the  Capital
Securities may, voting or consenting as a class, on behalf of the Holders of all
of the Capital Securities, waive any past Event of Default and its consequences.
Upon such waiver,  any such Event of Default shall cease to exist,  and shall be
deemed to have been  cured,  for every  purpose of this  Guarantee,  but no such
waiver shall extend to any  subsequent  or other  default or Event of Default or
impair any right consequent thereon.

         Section 2.5.  Events of Default; Notice.
                       -------------------------

of an Event of Default,  transmit by mail, first class postage  prepaid,  to the
Holders of the Capital  Securities and the  Guarantor,  notices of all Events of
Default actually known to a Responsible Officer of the Guarantee Trustee, unless
such  defaults  have been  cured  before the  giving of such  notice,  provided,
                                                                       --------
however,  that the  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 Capital Securities.

         (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 from the Guarantor or a Holder of the Capital  Securities  (except in the
case of a payment  default),  or a Responsible  Officer of the Guarantee Trustee
charged with the  administration  of this Guarantee  shall have obtained  actual
knowledge thereof.

         (c)    If the  Guarantee Trustee has or shall  acquire any "conflicting

         (a)    Subject  to  Section 3.2(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 in  accordance  with

accepted  such  appointment  by written  instrument  executed by such  Successor
Guarantee Trustee and delivered to the Guarantor.

         (c)    The  Guarantee  Trustee  appointed  to office  shall hold office

                                   GUARANTEE

         Section 4.1   Guarantee.
                       ---------

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

         (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  benefit  of,  and  to be  enforceable  by,  all  such
Beneficiaries, whether or not such Beneficiaries have received notice hereof.

         Section 4.2.  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 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 4.3.  Obligations  Not Affected.  The  obligations,  covenants,
                       -------------------------
agreements and duties of the Guarantor  under this Guarantee  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 Capital Securities to be performed
or observed by the Issuer;

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

         (c)    any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Capital 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;
<PAGE>

         (e)    any invalidity of,  or  defect  or deficiency  in,  the  Capital
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 4.3 that the  obligations of the Guarantor  hereunder
shall be absolute and unconditional under any and all circumstances.

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

         Section 4.4.  Rights of Holders.
                       -----------------

         (a)    The Holders of a Majority in liquidation  amount of the  Capital
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;  provided,  however,  that (subject to
                                           --------   -------
Section 2.1) the Guarantee Trustee shall have the right to decline to follow any
such direction if the Guarantee Trustee being advised by counsel determines that
the  action  or  proceeding  so  directed  may not  lawfully  be taken or if the
Guarantee Trustee in good faith by its board of directors or trustees, executive
committees  or a trust  committee of directors  or trustees  and/or  Responsible
Officers  shall  determine  that the action or  proceedings  so  directed  would
involve the Guarantee Trustee in personal liability.

         (b)    Any  Holder  of  Capital  Securities  may   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 Issuer,  the Guarantee  Trustee or any other  Person.  The Guarantor
waives any right or remedy to  require  that any such  action be  brought  first
against  the  Issuer,  the  Guarantee  Trustee  or any  other  Person  before so
proceeding directly against the Guarantor.

         Section 4.5.  Guarantee of Payment.  This Guarantee creates a guarantee
                       --------------------
of payment and not of collection.


         Section 4.6.  Subrogation. The Guarantor shall be subrogated to all (if
                       -----------
any) rights of the Holders of Capital  Securities  against the Issuer 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,
after giving  effect to 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 Holders.

         Section 4.7.  Independent Obligations.  The Guarantor acknowledges that
                       -----------------------
its obligations  hereunder are independent of the obligations of the Issuer with
respect to the  Capital  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 (a) through (g), inclusive, of Section 4.3 hereof.

         Section 4.8.  Enforcement by a Beneficiary.  A Beneficiary  may enforce
                       ----------------------------
the obligations of the Guarantor  contained in Section 4.1(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

<PAGE>

proceeding  against the  Guarantor.  The  Guarantor  shall be  subrogated to all
rights (if any) of any Beneficiary  against the Issuer in respect of any amounts
paid to the  Beneficiaries  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 rights 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,  and after giving effect to such payment,  any amounts
are due and unpaid under this Guarantee.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

         Section 5.1.  Limitation  of  Transactions.  So  long  as  any  Capital
                       ----------------------------
Securities  remain  outstanding,  if  (a)  there  shall  have  occurred  and  be
continuing  an Event of  Default  or a  Declaration  Event of Default or (b) the
Guarantor shall have selected an Extension Period as provided in the Declaration
and  such  period,  or  any  extension  thereof,  shall  have  commenced  and be
continuing,  then the Guarantor  shall not and shall not permit any Affiliate 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
or  such  Affiliate's  capital  stock  (other  than  payments  of  dividends  or
distributions  to the Guarantor) or make any guarantee  payments with respect to
the foregoing or (y) make any payment of principal of or interest or premium, if
any, on or repay,  repurchase or redeem any debt  securities of the Guarantor or
any Affiliate that rank pari passu in all respects with or junior in interest to
the  Debentures  (other  than,  with  respect to clauses (x) and (y) above,  (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 one or 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 the Event of  Default,  Declaration  Event of  Default or
Extension Period, as applicable,  (ii) as a result of any 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 of any class or 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
conversion or exchange  provisions  of such capital stock or the security  being
converted or exchanged,  (iv) any  declaration of a dividend in connection  with
any  stockholders'  rights  plan,  or the  issuance  of  rights,  stock or other
property under any stockholders' rights plan, or the redemption or repurchase of
rights  pursuant  thereto,  (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 and any cash  payments in lieu of  fractional  shares issued in connection
therewith, or (vi) payments under this Guarantee).

         Section 5.2.  Ranking.  This  Guarantee  will  constitute  an unsecured
                       -------
obligation  of the Guarantor  and will rank  subordinate  and junior in right of
payment  to all  present  and  future  Senior  Indebtedness  (as  defined in the
Indenture) of the Guarantor. By their acceptance thereof, each Holder of Capital
Securities  agrees to the foregoing  provisions of this  Guarantee and the other
terms set forth herein.

         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

<PAGE>

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  hereunder.  This  Guarantee  does not
limit the  incurrence  or issuance  of other  secured or  unsecured  debt of the
Guarantor,  including Senior Indebtedness of the Guarantor,  under any indenture
that the Guarantor may enter into in the future or otherwise.

                                   ARTICLE VI

                                   TERMINATION

         Section 6.1.  Termination.  This  Guarantee  shall  terminate as to the
                       -----------
Capital  Securities  (i) upon full  payment of the  Redemption  Price or Special
Redemption  Price of all  Capital  Securities  then  outstanding,  (ii) upon the
distribution  of all of the  Debentures  to the  Holders  of all of the  Capital
Securities or (iii) upon full payment of the amounts  payable in accordance with
the Declaration upon dissolution of the Issuer.  This Guarantee will continue to
be  effective  or will be  reinstated,  as the case  may be,  if at any time any
Holder of Capital  Securities  must  restore  payment of any sums paid under the
Capital Securities or under this Guarantee.

                                  ARTICLE VII

                                INDEMNIFICATION

         Section 7.1.  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 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  Issuer  or the  Guarantor  and upon such
information,  opinions,  reports or  statements  presented  to the Issuer or 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, if
selected by such Indemnified  Person,  has been selected with reasonable care by
such Indemnified Person, 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 Capital Securities might properly be paid.

         Section 7.2.  Indemnification.
                       ---------------

         (a)    The Guarantor agrees to  indemnify each Indemnified  Person for,
and to hold  each  Indemnified  Person  harmless  against,  any  and  all  loss,
liability,  damage,  claim or expense  incurred  without  negligence  or willful
misconduct  on  the  part  of  the  Indemnified  Person,  arising  out  of or in
connection  with  the  acceptance  or  administration  of the  trust  or  trusts
hereunder,  including,  but not  limited to, the costs and  expenses  (including
reasonable  legal fees and expenses) of the Indemnified  Person defending itself
against,  or  investigating,  any  claim or  liability  in  connection  with the
exercise or  performance  of any of the  Indemnified  Person's  powers or duties
hereunder.  The  obligation  to indemnify as set forth in this Section 7.2 shall
survive the resignation or removal of the Guarantee  Trustee and the termination
of this Guarantee.
<PAGE>

         (b)    Promptly  after  receipt  by  an  Indemnified  Person under this
Section 7.2 of notice of the commencement of any action, such Indemnified Person
will, if a claim in respect  thereof is to be made against the  Guarantor  under
this Section 7.2, notify the Guarantor in writing of the  commencement  thereof;
but the failure so to notify the  Guarantor  (i) will not relieve the  Guarantor
from  liability  under  paragraph  (a) above  unless and to the extent  that the
Guarantor did not otherwise learn of such action and such failure results in the
forfeiture  by the  Guarantor of  substantial  rights and defenses and (ii) will
not, in any event, relieve the Guarantor from any obligations to any Indemnified
Person  other than the  indemnification  obligation  provided in  paragraph  (a)
above.  The Guarantor  shall be entitled to appoint  counsel of the  Guarantor's
choice at the  Guarantor's  expense to represent the  Indemnified  Person in any
action for which  indemnification  is sought (in which case the Guarantor  shall
not thereafter be responsible for the fees and expenses of any separate  counsel
retained  by the  Indemnified  Person or  Persons  except  as set forth  below);
provided,  however,  that such counsel shall be reasonably  satisfactory  to the
--------   -------
Indemnified Person.  Notwithstanding the Guarantor's election to appoint counsel
to represent the Guarantor in an action,  the Indemnified  Person shall have the
right to employ separate counsel  (including  local counsel),  and the Guarantor
shall bear the reasonable  fees,  costs and expenses of such separate counsel if
(i) the use of counsel  chosen by the  Guarantor  to represent  the  Indemnified
Person would  present such counsel with a conflict of interest,  (ii) the actual
or  potential  defendants  in, or targets of, any such action  include  both the
Indemnified  Person and the  Guarantor  and the  Indemnified  Person  shall have
reasonably  concluded  that there may be legal  defenses  available to it and/or
other  Indemnified  Person(s)  which are  different  from or additional to those
available to the Guarantor,  (iii) the Guarantor shall not have employed counsel
satisfactory  to the  Indemnified  Person to represent  the  Indemnified  Person
within a reasonable  time after notice of the institution of such action or (iv)
the Guarantor shall authorize the Indemnified  Person to employ separate counsel
at the  expense of the  Guarantor.  The  Guarantor  will not,  without the prior
written consent of the Indemnified  Persons,  settle or compromise or consent to
the entry of any  judgment  with  respect to any  pending or  threatened  claim,
action,  suit or proceeding in respect of which  indemnification or contribution
may be sought  hereunder  (whether or not the Indemnified  Persons are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent  includes an unconditional  release of each Indemnified  Person from all
liability arising out of such claim, action, suit or proceeding.

         Section 7.3.  Compensation;  Reimbursement  of Expenses.  The Guarantor
                       -----------------------------------------
agrees:


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