Preferred Securities, which purchase the Guarantor hereby agrees shall benefit

specifically set forth in this Preferred Securities Guarantee, and no implied

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 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 Preferred Guarantee
      Trustee shall be determined solely by the express provisions of this
      Preferred Securities Guarantee, and the Preferred 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 Guarantee
      Trustee; and

                     (B) in the absence of bad faith on the part of the
      Preferred Guarantee Trustee, the Preferred 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 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

                          10




    




     required to be furnished to the Preferred Guarantee Trustee, the
     Preferred 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;



                (ii) the Preferred Guarantee Trustee shall not be liable for
      any error of judgment made in good faith by a Responsible Officer of the
      Preferred Guarantee Trustee, unless it shall be proved that the
      Preferred Guarantee



      Trustee was negligent in ascertaining the per-
      tinent facts upon which such judgment was made;

                (iii) the Preferred 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 preference of the Preferred Securities at the
      time outstanding, relating to the time, method and place of conducting
      any proceeding for any remedy available to the Preferred Guarantee
      Trustee, or exercising any trust or power conferred upon the Preferred
      Guarantee Trustee under this Preferred Securities Guarantee; and

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

      might be incurred by it in complying with such request or direction,
      including such reasonable advances as may be requested by the Preferred
      Guarantee Trustee; provided that nothing contained in this Section
      3.2(a)(vi) shall be taken to relieve the Preferred Guarantee Trustee,
      upon the occurrence of an Event of Default, of its obligation to exercise
      the rights and powers vested in it by this Preferred Securities Guarantee;

      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 Guarantee Trustee's
      or its agent's taking such action; and

conferred or imposed on it, in any jurisdiction in which it shall be illegal,
or in which the Preferred 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

                              14




    



authority available to the Preferred Guarantee Trustee shall be construed
to be a duty.

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

                (i)  not be an Affiliate of the Guar-
      antor; and

                (ii) be a corporation organized and doing business under the

      Columbia authority. If such corporation publishes reports of condition
      at least annually, pursuant to law or to the requirements of the
      supervising or examining authority referred to above, then, for the
      purposes of this Section 4.1(a)(ii), the combined capital and surplus of
      such corporation shall be deemed to be its combined

                             15




    



      capital and surplus as set forth in its most recent report of condition
      so published.

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

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


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

           (a) Subject to ss. 4.2(b), the Preferred Guarantee Trustee may be
appointed or removed without cause at any time by the Guarantor.

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

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

           (c) The Preferred Guarantee Trustee appointed to office shall hold
office until a Successor Preferred Guarantee Trustee shall have been appointed
or until its removal or resignation. The Preferred Guarantee Trustee may
resign from office (without need for prior or subsequent accounting) by an
instrument in writing executed by the Preferred Guarantee Trustee and
delivered to the Guarantor, which resignation shall not take effect until a
Successor Preferred Guarantee Trustee has been appointed and has accepted such
appointment by instrument in writing executed by such Successor Preferred
Guarantee Trustee and delivered to the Guarantor and the resigning Preferred
Guarantee Trustee.

appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery of an instrument of removal or resignation, the Preferred
Guarantee Trustee resigning or being removed may petition any court of
competent jurisdiction for appointment of a Successor Preferred Guarantee
Trustee. Such court may thereupon, after prescribing such notice, if any, as
it may deem proper, appoint a Successor Preferred Guarantee Trustee.

           (e) No Preferred Guarantee Trustee shall be liable for the acts or
omissions to act of any Successor Preferred Guarantee Trustee.

           (f) Upon termination of this Preferred Securities Guarantee or
removal or resignation of the Preferred Guarantee Trustee pursuant to this
Section 4.2, the Guarantor shall pay to the Preferred Guarantee Trustee
all amounts accrued and payable to the Preferred Guarantee Trustee to the date
of such termination, removal or resignation.

                            GUARANTEE

SECTION 5.1     Guarantee.

           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,
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.

SECTION 5.2     Subordination

           If an Event of Default (as defined in the Indenture), has occurred
and is continuing, the rights of Holders of the Common Securities to receive
Guarantee Payments under the Common Securities Guarantee are subordinated to
the rights of Holders of Preferred

                             17




    




Securities to receive Guarantee Payments under this Preferred Securities
Guarantee.

SECTION 5.3     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 5.4     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, the amount payable upon redemption,
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, the
amount payable upon redemption, 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

                              18




    



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 obli-
gation 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 5.4 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 or any other Person to
give notice to, or obtain consent of, the Guarantor with respect to the
happening of any of the foregoing.

SECTION 5.5     Rights of Holders.

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

           (b) Any Holder of Preferred Securities may directly institute a
legal proceeding against the Guarantor to enforce the payment obligations of
the Guarantor under this Preferred Securities Guarantee without first
instituting a legal proceeding against the Trust, the Preferred Guarantee
Trustee or any other Person.

                             19




    





           (c) If an Event of Default with respect to the Debentures (an
"Indenture Event of Default"), constituting the failure to pay interest or
principal on the Debentures on the date such interest or principal is
otherwise payable (or in the case of any redemption, the redemption date) has
occurred and is continuing, then a Holder of Preferred Securities may
directly, at any time, institute a proceeding for enforcement of payment to
such Holder of the principal of or interest on the Debentures having a
principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such Holder on or after the respective due date (or redemption
date) specified in the Debentures.

SECTION 5.6     Guarantee of Payment.

           This Preferred Securities Guarantee creates a guarantee of payment
and not of collection.

SECTION 5.7     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 5.8     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


                             20




    



terms of this Preferred Securities Guarantee notwithstanding the occurrence of
any event referred to in subsections (a) through (g), inclusive, of Section
5.4 hereof.

SECTION 5.9     Conversion

           The Guarantor acknowledges its obligation to issue and deliver
common stock upon the conversion of the Preferred Securities.

                   LIMITATION OF TRANSACTIONS; SUBORDINATION

SECTION 6.1     Limitation of Transactions.

           So long as any Preferred Securities remain outstanding, if at such
time (i) the Guarantor has exercised its option to defer interest payments on
the Debentures and such deferral is continuing, (ii) the Guarantor


shall be in default with respect to its payment or other obligations under
this Preferred Securities Guarantee or (iii) there shall have occurred and be
continuing any event that, with the giving of notice or the lapse of time or
both, would constitute an Event of Default under the Indenture, then the
Guarantor (a) shall not declare or pay any dividend on, or make any
distribution with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than
stock dividends paid by the Guarantor which consist of the stock of the same
class as that on which the dividend is being paid), (b) 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 after the date hereof that
ranks pari passu with or junior to the Debentures and (c) shall not make any
guarantee payments with respect to the foregoing (other than pursuant to this
Preferred Securities Guarantee).

                             21




    




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
that may be made pari passu expressly by their terms, (ii) pari passu with the
most senior preferred or preference stock issued by the Guarantor after the
date hereof and with any guarantee now or hereafter entered into by the
Guarantor in respect of any preferred or preference stock or Preferred
Security of any Affiliate of the Guarantor, and (iii) senior to the
Guarantor's common stock.


                                  ARTICLE VII
                                  TERMINATION

SECTION 7.1     Termination.

           This Preferred Securities Guarantee shall terminate upon (i) full
payment of the amount payable upon redemption of all Preferred Securities,
(ii) the distribution of the Guarantor's common stock to the Holders in
respect of the conversion of the Preferred Securities into the Guarantor's
common stock or the dis-


tribution of the Debentures to the Holders of all of the Preferred Securities
or (iii) full payment of the amounts payable in accordance with the
Declaration upon liquidation of the Issuer. 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.

incurred by reason of such Indemnified Person's negligence or willful
misconduct with respect to such acts or omissions.

undertaking by or on behalf of the Indemnified Person to repay such amount if
it shall be determined that the Indemnified Person is not entitled to be
indemnified as authorized in Section 8.2(a).
