                     PREFERRED SECURITIES GUARANTEE TRUSTEE

     SECTION 3.1  Powers and Duties of the Preferred Securities Guarantee
                  Trustee

          (a)  This Preferred Securities Guarantee shall be held by the
Preferred Securities Guarantee Trustee for the benefit of the Holders of the
Preferred Securities, and the Preferred Securities Guarantee Trustee shall not
transfer this Preferred Securities Guarantee to any Person except a Holder of
Preferred Securities exercising his or her rights pursuant to Section 5.4(b) or
to a Successor Preferred Securities Guarantee Trustee on acceptance by such
Successor Preferred Securities Guarantee Trustee of its appointment to act as
Successor Preferred Securities Guarantee Trustee. The right, title and interest
of the Preferred Securities Guarantee Trustee shall automatically vest in any
Successor Preferred Securities Guarantee Trustee, 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
Preferred Securities Guarantee Trustee.

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

<PAGE>

paid to the Preferred Securities Guarantee Trustee for amounts due under Section
8.3 and then to the Holders of the Preferred Securities.

          (c)  The Preferred Securities 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 Preferred Securities Guarantee, and no implied covenants shall
be read into this Preferred Securities Guarantee against the Preferred
Securities Guarantee Trustee. In case an 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 Preferred Securities Guarantee Trustee, the Preferred
Securities Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Preferred Securities 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 Preferred Securities Guarantee shall be
construed to relieve the Preferred Securities Guarantee Trustee from liability
for its own negligent action, its own negligent failure to act, its own bad
faith, 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 Preferred Securities
          Guarantee Trustee shall be determined solely by the express provisions
          of this Preferred Securities Guarantee, and the Preferred Securities
          Guarantee Trustee shall not be liable except for the performance of
          such duties and obligations as are specifically set forth in this
          Preferred Securities Guarantee, and no implied covenants or
          obligations shall be read into this Preferred Securities Guarantee
          against the Preferred Securities Guarantee Trustee; and

                     (B)  in the absence of bad faith on the part of the
          Preferred Securities Guarantee Trustee, the Preferred Securities
          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 Preferred Securities
          Guarantee Trustee and conforming to the requirements of this Preferred
          Securities Guarantee; but in the case of any such certificates or
          opinions that by any provision hereof are specifically required to be
          furnished to the Preferred Securities Guarantee Trustee, the Preferred
          Securities Guarantee Trustee shall be under a duty to examine the same
          to determine whether or not they conform to the requirements of this
          Preferred Securities Guarantee (but shall not be required to confirm
          or investigate the accuracy of mathematical calculations or other
          facts stated therein);

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

               (iii) the Preferred Securities 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
     Preferred Securities Guarantee Trustee, or exercising any trust or power
     conferred upon the Preferred Securities Guarantee Trustee under this
     Preferred Securities Guarantee; and

               (iv)  no provision of this Preferred Securities Guarantee shall
     require the Preferred Securities 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 Preferred Securities 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 Preferred Securities
     Guarantee or if indemnity reasonably satisfactory to the Preferred
     Securities Guarantee Trustee against such risk or liability is not
     reasonably assured to it.

     opinion, report, notice, request, direction, consent, order, bond,
     debenture, note, other evidence of indebtedness or other paper or document

               (iii)  whenever, in the administration of this Preferred
     Securities Guarantee, the Preferred Securities Guarantee Trustee shall deem
     it desirable that a matter be proved or established before taking,
     suffering or omitting any action hereunder, the Preferred Securities
     Guarantee Trustee (unless other evidence is herein specifically prescribed)

     request, shall be promptly delivered by the Guarantor;

               (iv)   the Preferred Securities Guarantee Trustee shall have no

     thereof;

               (v)    the Preferred Securities Guarantee Trustee may consult
     with counsel of its selection, and the advice or written opinion of such

     reasonable expenses of the Preferred Securities Guarantee Trustee's agents,
     nominees or custodians) and liabilities that might be incurred by it in

     vested in it by the terms of this Preferred Securities Guarantee;

               (vii)  the Preferred Securities Guarantee Trustee shall not be

     of the trusts or powers hereunder or perform any duties hereunder either
     directly or by or through agents, nominees, custodians or attorneys, and

     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
     Preferred Securities Guarantee Trustee to so act or as to its compliance
     with any of the terms and provisions of this Preferred Securities
     Guarantee, both of which shall be conclusively evidenced by the Preferred
     Securities Guarantee Trustee's or its agent's taking such action;

               (x)   whenever in the administration of this Preferred Securities
          Guarantee the Preferred Securities Guarantee Trustee shall deem it
          desirable to receive instructions with respect to enforcing any remedy
          or right or taking any other action hereunder, the Preferred
          Securities 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 conclusively relying on or acting in accordance
          with such instructions;

               (xi)  except as otherwise expressly provided by this Preferred

     liable for any action taken, suffered, or omitted to be taken by it in good
     faith, without negligence, and reasonably believed by it to be authorized
     or within the discretion or rights or powers conferred upon it by this
     Preferred Securities Guarantee.

               (b)   No provision of this Preferred Securities Guarantee shall
be deemed to impose any duty or obligation on the Preferred Securities 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 Preferred Securities 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 Preferred Securities Guarantee
Trustee shall be construed to be a duty.

                   Securities Guarantee

                   Guarantee Trustee

          (a) Subject to Section 4.2(b), the Preferred Securities Guarantee

except during the occurrence and continuance of an Event of Default.

          (b) The Preferred Securities Guarantee Trustee shall not be removed in

Trustee has been appointed and has accepted such appointment by written
instrument executed by such Successor Preferred Securities Guarantee Trustee and
delivered to the Guarantor.

          (c) The Preferred Securities Guarantee Trustee shall hold office until
a Successor Preferred Securities Guarantee Trustee shall have been appointed or
until its removal or resignation. The Preferred Securities Guarantee Trustee may
resign from office (without need for prior or subsequent accounting) by an

Trustee.

                                    ARTICLE V
                                    GUARANTEE

     SECTION 5.1  Guarantee

     The Guarantor irrevocably and unconditionally agrees to pay in full, on a
subordinated basis, to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by the Issuer), as and when due, regardless of any
defense, right of set-off or counterclaim that the Issuer may have or assert
(other than the defense of payment). 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 will honor all obligations, if any, relating to the
conversion of the Preferred Securities into securities of the Guarantor as set
forth in the Agreement and the Indenture.

                                        9

     SECTION 5.2  Waiver of Notice and Demand

     The Guarantor hereby waives notice of acceptance of this Preferred
Securities 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 5.3  Obligations Not Affected

     The obligations, covenants, agreements and duties of the Guarantor under
this Preferred Securities 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 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, 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 (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 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 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 the obligations of the Guarantor
with respect to the Guarantee Payments 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 5.4  Rights of Holders

          (a)  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 Preferred Securities Guarantee
Trustee in respect of this Preferred Securities Guarantee or exercising any
trust or power conferred upon the Preferred Securities Guarantee Trustee under
this Preferred Securities Guarantee.

          (b)  If the Preferred Securities Guarantee Trustee fails to enforce
this Preferred Securities Guarantee, any Holder of Preferred Securities may
institute a legal proceeding directly against the Guarantor to enforce the
rights of such Holder under this Preferred Securities Guarantee, without first
instituting a legal proceeding against the Issuer,

                                       10

<PAGE>

the Preferred Securities Guarantee Trustee or any other person or entity. The
Guarantor waives any right or remedy to require that any action be brought first
against the Issuer or any other person or entity before proceeding directly
against the Guarantor.

     Notwithstanding the foregoing, if the Guarantor has failed to make a
required Guarantee Payment, a Holder of Preferred Securities may directly
institute a proceeding against the Guarantor for enforcement of this Preferred
Securities Guarantee for such Guarantee Payment.

     SECTION 5.5  Guarantee of Payment

     This Preferred Securities 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
Preferred Securities against the Issuer in respect of any amounts paid to such
Holders by the Guarantor under this Preferred Securities 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 Preferred Securities
Guarantee, if, at the time of any such payment, any amounts are due and unpaid
under this Preferred Securities 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 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 Preferred Securities Guarantee
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

capital stock (which includes common and preferred stock) or (ii) make any
payment of principal, interest or premium, if any, on or repay or repurchase or

of the debt securities of any subsidiary of the Guarantor (including Other

the Debentures (other than (a) dividends or distributions in shares of, or
options, warrants or rights to subscribe for or purchase shares of, common stock
of the Guarantor, (b) any declaration of a dividend in connection with the
implementation of a stockholders' rights plan, or the issuance of stock under
any such plan in the future, or the redemption or repurchase of any such rights
pursuant thereto, (c) payments under the Preferred Securities Guarantee, (d) as
a result of a reclassification of the Guarantor's capital stock or the exchange
or the conversion of one class or series of the Guarantor's capital stock for
another class or series of the Guarantor's capital stock, (e) 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, and (f) purchases of common stock related to the
issuance of common stock or rights under any of the Guarantor's benefit plans
for its directors, officers or employees or any of the Guarantor's dividend
reinvestment plans) if at such time (i) there shall have occurred any event of
which the Guarantor has actual knowledge that is, or with the giving of notice
or the lapse of time, or both, would be an Event of Default, (ii) the Guarantor
shall be in default with respect to its payment obligations under this Preferred
Securities Guarantee or (iii) the Guarantor shall have given notice

                                       11

<PAGE>

of its election of the exercise of its right to extend the interest payment
period pursuant to Section 4.01(b) of the Indenture and shall not have rescinded
such notice, and any such extension shall have commenced and be continuing.

     SECTION 6.2  Ranking

     This Preferred Securities Guarantee 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 any liabilities (including the
Other Guarantees, the Common Securities Guarantee and the Other Common
Securities Guarantees) that may be pari passu or junior expressly by their
terms, and (ii) senior to the Guarantor's capital stock now or hereafter issued
by the Guarantor, if any, and with any guarantee now or hereafter entered into
by the Guarantor in respect of any of the Guarantor's capital stock. The
foregoing subordination shall not apply to amounts payable under Article VIII.

                                   ARTICLE VII

force and effect upon (i) full payment of the Redemption Price of all Preferred
Securities, or (ii) liquidation of the Issuer, the full payment of the amounts
payable in accordance with the Agreement or the distribution of the Debentures
to the Holders of all of the Preferred Securities. Notwithstanding the
foregoing, this Preferred Securities Guarantee will continue to be effective or
will be reinstated, as the case may be, if at any time any Holder of Preferred
Securities must restore payment of any sums paid under the Preferred Securities
or under this Preferred Securities Guarantee.

                                  ARTICLE VIII

receive evidence to their satisfaction of the destruction, loss or theft of any

of the Company who shall have signed any of the Warrants (manually or in
facsimile) shall cease to be such officer before the Warrants so signed shall
have been authenticated and delivered by the Agent, such Warrants nevertheless
may be authenticated and delivered as though the Person who signed such Warrants

<PAGE>

     The items described in the foregoing clauses (a) and (b) shall be deemed
received when an actual copy or a facsimile thereof is received by the Agent.
Each Warrant shall be deemed to be surrendered only upon personal delivery
thereof to or, if sent by mail or other means of transmission, upon receipt
thereof by, the Agent at the office specified in this Section 4.1. Each Warrant
shall be deemed exercised as of the first Business Day on which all of the
foregoing conditions are satisfied with respect to such Warrant. The first day
on which the Warrants may be exercised is ________________, ____________, ___.
The Company acknowledges that the Registered Owners of the Warrants are not
required under any circumstances to take any other actions in order to exercise
their Warrants.

     SECTION 4.2. EFFECT OF EXERCISE OF WARRANTS. Upon surrender and payment of
the Exercise Price by the Registered Owner of any Warrant in accordance with
Section 4.1, the [Notes/Debentures] so purchased shall be deemed to have been
issued and the person or persons to whom such [Notes/Debentures] are to be
issued shall be deemed to have become the Registered Owner or owners of such
[Notes/ Debentures] on the [Exercise Date].

     After the due exercise of a Warrant as aforesaid, the Company shall
forthwith cause to be delivered to the person to whom the [Notes/Debentures] so
purchased are to be issued at the address specified in such form or, if so
specified in such purchase form, cause to be delivered to such person at the
office where such Warrant was surrendered, a [Note/Debenture] or
[Notes/Debentures] in the form or forms and in the denominations requested and
for the appropriate principal amount of [Notes/Debentures] not exceeding the
principal amount which the Warrantholder is entitled to purchase pursuant to the
Warrant surrendered.

     SECTION 4.3. PARTIAL EXERCISE OF WARRANTS. Subject to the issuance of
[Notes/Debentures] in authorized denominations only, the Registered Owner of any
Warrant may purchase [Notes/Debentures] in a principal amount less than that
which such Registered Owner is entitled to purchase pursuant to the surrendered
Warrant. In the event of any purchase of a principal amount of
[Notes/Debentures] less than the principal amount which can be purchased
pursuant to a Warrant, the Registered Owner thereof upon exercise thereof prior
to the Time of Expiry shall, in addition, be entitled to receive forthwith a new
Warrant in respect of the balance of the principal amount of [Notes/Debentures]
which such Registered Owner was entitled to purchase pursuant to the surrendered
Warrant and which were not then exercised. The Company shall not be responsible
for any taxes which may be payable in connection with the issuance of such new
Warrant.

     SECTION 4.4. EXPIRATION OF WARRANTS. After the Time of Expiry, all rights
under any Warrant in respect of which the right of purchase herein and therein
provided for shall not theretofore have been exercised pursuant to Section 4.1
shall cease and terminate and such Warrant shall become void and of no effect
and all rights of the Registered Owner thereof under this Warrant Agreement
shall cease and terminate as of such termination; provided that such Registered
Owner's rights under this Warrant Agreement with respect to actions occurring
prior to such termination shall remain in full force. After the Time of Expiry,
each Registered Owner of any Warrants shall return any unexercised Warrants to
the Agent for cancelation in accordance with Section 4.5 of this Agreement.

     SECTION 4.5. CANCELATION OF SURRENDERED WARRANTS. All Warrants surrendered
to the Agent pursuant to Sections 2.3, 3.2, 3.4 or 4.1 shall forthwith be
canceled by the Agent. All Warrants canceled or required to be canceled under
this or any other provision of this Agreement may be destroyed by or under the
direction of the Agent and the Agent shall furnish the Company with a
destruction certificate identifying the Warrants so destroyed and the principal
amount of [Notes/Debentures] which could have been purchased pursuant to each.

     SECTION 4.6. ACCOUNTING AND RECORDING. The Agent shall forthwith account
and remit to the Company with respect to Warrants exercised and immediately
forward to the Company (or into an account or accounts of the Company with the
bank or trust company designated by the Company for that purpose) all monies
received by the Agent on the purchase of [Notes/Debentures] through the exercise
of Warrants. All such monies, and any [Notes/Debentures] or other instruments,
from time to time received by the Agent shall be received in trust for, and
shall be segregated and kept apart by the Agent in trust for, the Company.

     the proceeds of the Warrants.

         (h) The Agent shall be obligated to perform such duties and only such

     SECTION 9.4. RESIGNATION AND REMOVAL OF AGENT; APPOINTMENT OF SUCCESSOR.
The Agent may at any time resign by giving written notice (in accordance with
Section 10.1 hereof) to the Company of such intention on its part, specifying
the date on which its desired resignation shall become effective; provided,
however, that such date shall never be less than [90] days after the receipt of
such notice by the Company unless the Company agrees to accept less notice. Upon
receipt of such notice of resignation, the Company shall promptly act to appoint
a successor Agent. The Agent may be removed at any time by the Company by
delivering written notice thereof specifying such removal and the date when it
is intended to become effective. Any resignation or removal of the Agent shall
take effect upon the date of the appointment by the Company as hereinafter
provided of a successor and the acceptance of such appointment by such
successor.

     In case at any time the Agent shall resign, or shall be removed, or shall
become incapable of acting or shall be adjudged as bankrupt or insolvent, or if
a receiver of its or of its property shall be appointed, or if any public
officer shall take charge or control of its or of its property or affairs, for
the purpose of rehabilitation, conservation or liquidation, a successor agent,
eligible as aforesaid, shall be appointed by the Company. Upon the appointment
as aforesaid of a successor agent and acceptance by it of such appointment, the
Agent so superseded shall cease to be the Agent hereunder. If no successor Agent
shall have been so appointed by the Company and shall have accepted appointment
as hereinafter provided, then the Registered Owners of a majority in aggregate
principal amount of the Outstanding Warrants, on such Holders' behalf and on
behalf of all others similarly situated may petition any court of competent
jurisdiction for the appointment of a successor Agent.

     Any successor Agent appointed hereunder shall execute, acknowledge and
deliver to its predecessor and to the Company an instrument accepting such
appointment hereunder, and thereupon such successor Agent, without any further
act deed or conveyance, shall become vested with all the authority, rights,
powers, immunities, duties and obligations of such predecessor with like effect
as if originally named as such Agent hereunder, and such predecessor, upon
payment of its charges and disbursements then unpaid, shall simultaneously
therewith become obligated to transfer, deliver and pay over, and such successor
Agent shall be entitled to receive, all moneys, [Notes/Debentures] or other
property on deposit with or held by such predecessor, as such Agent hereunder.
The Company or, at the discretion of the Company, the successor Agent, will give
prompt written notice by U.S. Mail to each Registered Owner of the Warrants at
such owner's address as it appears on the Register of the appointment of a
successor Agent. Failure to give such notice or any defect therein shall not
affect the appoint of a successor Agent.

     SECTION 9.5. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS OF
AGENT. Any corporation into which the Agent may be merged or converted, or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Agent shall be a party, or any
corporation succeeding to all or substantially all the assets and business of
the Agent, shall be the successor to the Agent hereunder, provided such
corporation shall be otherwise eligible under this Article VII, without the
execution or filing of any document or any further act on the part of any of the
parties hereto.

     In case any Warrants shall have been authenticated, but not delivered, by
the Agent then in office, any successor by merger, conversion or consolidation
to such authenticating Agent may adopt such authentication and deliver the
Warrants so authenticated with the same effect as if such successor Agent had
itself authenticated such Warrants.

                                    ARTICLE X
                                  MISCELLANEOUS

     SECTION 10.1. NOTICES. All notices or demands hereunder upon the Company or

overnight courier, addressed to any party hereto as provided in this Section
10.1.

executed in any number of counterparts, each of which shall for all purposes be
