THE FIRST NATIONAL BANK OF CHICAGO,
   AS TRUSTEE


BY
   -------------------------------------
   AUTHORIZED OFFICER



                              REVERSE OF DEBENTURES

     This Debenture is one of a duly authorized issue of debentures, notes,
bonds or other evidences of indebtedness of the Company (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated as of December 1, 1982 (herein called
the "Indenture"), duly executed and delivered by the Company to The First
National Bank of Chicago (as successor trustee to Morgan Guaranty Trust Company
of New York), Trustee (herein called the "Trustee"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and holders of the Securities. The Securities may be
issued in one or more series, which different series may be issued in various
aggregate principal amounts, may mature at different times, may bear interest
(if any) at different rates, may be subject to different redemption provisions
(if any), may be subject to different sinking, purchase or analogous funds (if
any), may be subject to different covenants and Events of Default and may
otherwise vary as in the Indenture provided. This Debenture is one of a series
designated as the 7-3/4% Debentures Due August 1, 2029 of the Company, limited
in aggregate principal amount to $300,000,000.

     In case an Event of Default with respect to the 7-3/4% Debentures Due
August 1, 2029 shall have occurred and be continuing, the principal hereof may
be declared, and upon such declaration shall become due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than 66-2/3% in aggregate principal
amount of the Securities at the time outstanding of all series to be affected
(voting as a class), evidenced as in the Indenture provided, to execute
supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or modifying in any manner the rights of the holders of the Securities
of each such series; provided, however, that no such supplemental indenture
shall (i) extend the final maturity of any Security, or reduce the rate or
extend the time of payment of interest thereon, or reduce the principal amount
thereof or any premium thereon, or reduce any amount payable on redemption
thereof or make the principal thereof or any interest of premium thereon payable
in any coin or currency other than that hereinbefore provided, or impair or
affect the right of any holder to institute suit for payment thereof or the
right of repayment, if any, at the option of the holder, without the consent of
the holder of each Security so affected, or (ii) reduce the aforesaid principal
amount of Securities of all series to be affected, the holders of which are
required to consent to any such supplemental indenture, without the consent of
the holders of all Securities so affected then outstanding. It is also provided
in the Indenture that, with respect to certain defaults or Events of Default
regarding the Securities of any series, prior to any declaration accelerating
the maturity of such Securities, the holders of a majority in aggregate
principal amount of the Securities of such series at the time outstanding (or,
in the case of certain defaults or Events of Default, all the Securities) may on
behalf of the holders of all of the Securities of such series (or all the
Securities, as the case may be) waive any such past default or Event of Default
under the Indenture and its consequences except a default in the payment of
principal of, premium, if any, or interest, if any, on any of the Securities.
Any such consent or waiver by the holder of this



Debenture (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such holder and upon all future holders and owners of this
Debenture and any Debentures which may be issued in exchange or transfer hereof
or in substitution herefor, irrespective of whether or not any notation thereof
is made upon this Debenture or such other Debentures.

     No reference herein to the Indenture and no provision of this Debenture or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Debenture at the place, at the respective times, at the rate and in the coin or
currency herein prescribed.

     The Debentures are issuable in registered form without coupons in
denominations of $1,000 and any multiple of $1,000. Upon due presentment for
registration of transfer of this Debenture at the office or agency of the
Company for such registration in the Borough of Manhattan, The City of New York,
or any other location or locations as may be provided for pursuant to the
Indenture, a new Debenture or Debentures of authorized denominations for an
equal aggregate principal amount will be issued to the transferee in exchange
therefor, subject to the limitations provided in the Indenture, without charge
except for any tax or other governmental charge imposed in connection therewith.

     The Debentures may not be redeemed prior to maturity.

     The Debentures will be subject to defeasance and discharge and to
defeasance of certain obligations as set forth in the Indenture.

     The Company, the Trustee and any agent of the Company or the Trustee may
deem and treat the holder hereof as the absolute hereof (whether or not this
Debenture shall be overdue and notwithstanding any notation of ownership or
other writing hereon), for the purpose of receiving payment of or on account of
the principal hereof and, subject to the provisions on the face hereof, interest
hereon, and for all other purposes, and neither the Company nor the Trustee nor
any such agent shall be affected by any notice to the contrary. All payments
made to or upon the order of such holder shall, to the extent of the sum or sums
paid, effectually satisfy and discharge liability for moneys payable hereon.

     No recourse for the payment of the principal of, or premium, if any, or
interest on this Debenture, or for any claim based hereon or otherwise in
respect hereof, and no recourse under or upon any obligation, covenant or
agreement of the Company in the Indenture or any indenture supplemental thereto
or in any Debenture, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.



     All terms used in this Debenture which are defined in the Indenture shall
have the respective meanings ascribed to them therein.

     This Debenture shall be deemed to be a contract made under the laws of the
State of New York, and for all purposes shall be construed in accordance with
and governed by the laws of that State.
