                     7% SENIOR NOTES DUE SEPTEMBER 15, 2004


1.   DESIGNATION

     This Security is one of a duly authorized series of Securities of the
Company, designated as its 7% Senior Notes Due September 15, 2004 (herein called
the "Securities"), limited to the aggregate principal amount of $100,000,000,
all issued or to be issued under and pursuant to a senior indenture dated as of
July 1, 1993 (herein called the "Indenture"), duly executed and delivered by the
Company and LaSalle National Bank, as successor Trustee (herein called the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and
the Holders of the Securities. Capitalized terms used but not defined herein are
defined in the Indenture and are used herein with the same meanings as ascribed
to them therein. 

2. PAYING AGENT AND REGISTRAR

       Initially, the Trustee will act as Paying Agent, Registrar and as the
agent where notices and demands to or upon the Company in respect of the
Securities may be served. The Company may appoint and change any Paying Agent,
Registrar or agent for notices without notice, other than notice to the Trustee.
The Company or any of its Subsidiaries or any of their Affiliates may act as
Paying Agent, Registrar or agent for notices.

3.   DENOMINATIONS; TRANSFERS; EXCHANGE

       The Securities are in registered form, without coupons, in denominations
of $1,000 in principal amount and integral multiples of $1,000. Upon due
presentation for registration of transfer of this Security at the corporate
trust office of the Trustee in the City of Chicago, State of Illinois or any
other such designated office or agency of the Company, a new Security or
Securities of authorized denominations for an equal aggregate principal amount
will be issued to the transferee in exchange herefor, subject to the limitations
imposed by the Indenture, without charges except for any tax or other
governmental charge imposed in connection therewith, and the Security may in a
like manner be exchanged for one or more new Securities of other authorized
denominations but of the same aggregate principal amount.

4.   PERSONS DEEMED OWNERS

     The Company, the Trustee, any Paying Agent and any Registrar may deem and
treat the registered Holder hereof as the absolute owner of this Security
(whether or not this Security shall be overdue and notwithstanding any notation
of ownership or other writing herein made by anyone other than the Company, the
Trustee or any Registrar) for purposes of receiving payment hereof, or on
account hereof, and for all other purposes, and neither the Company, the
Trustee, any Paying Agent nor any Registrar shall be affected by any notice to
the contrary. All payments made to or upon the order of such registered Holder
shall, to the extent of the sum or sums so paid, satisfy and discharge the
liability for moneys payable on this Security. 

5. DEFAULTS; AMENDMENTS; WAIVER

       In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal hereof and the interest accrued
thereon 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 a majority in aggregate
principal amount of each series of Securities then Outstanding under the
Indenture and affected thereby, evidenced as provided in the Indenture, 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; provided, however, that no such supplemental indenture shall (i)
extend the final maturity of any Security, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
change the coin or currency in which payments are to be made, impair or affect
the right of any Holder to institute suit for enforcement of any payment thereof
or (ii) reduce the aforesaid percentage of any series of such Securities, the
consent of the Holders of which is required for any such supplemental indenture,
without the consent of the Holders of each Security of any series so affected.
It is also provided in the Indenture that the Holders of not less than a
majority in aggregate principal amount of the Securities of any series then
Outstanding may on behalf of the Holders of all of the Securities of such series
waive any past default under the Indenture and its consequences except a default
in the payment of the principal of or interest on any of the Securities of such
series. Any such consent or waiver by the Holder of this Security (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
Holder and upon all future Holders and owners of this Security and any
Securities which may be issued in exchange or substitution herefor, irrespective
of whether or not any notation thereof is made upon this Security or such other
Securities. 

       No reference herein to the Indenture and no provision of this Security 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
Security at the place, at the respective times, and at the rate and in the coin
or currency herein provided.

6. NO RECOURSE AGAINST OTHERS 

       No recourse shall be had for the payment of the principal of or interest
on this Security, or for any claim based hereon, or otherwise in respect hereof,
or based on or in respect of the Indenture or any indenture supplemental thereto
against any incorporator, stockholder, officer or director, as such, past,
present or future, of the Company or any partner of the Company or of any
successor corporation, either directly or through the Company or any successor
corporation, under any rule of law, statute or constitutional provision or by
the enforcement of any assessment or legal or equitable proceeding or otherwise,
all such liability being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.

7. GOVERNING LAW 

       THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
