Payment Date (as defined below) to which interest has been paid or duly provided
for semi-annually in arrears on June 15 and December 15 in each year ("Interest

Maturity or upon redemption.  Interest will be payable to the Holder at the
close of business on the Regular Record Date (which shall be May 31 and November
30 of each year) next preceding such Interest Payment Date.  If the Original
Issue Date is between a Regular Record Date and the next succeeding Interest

"Defaulted Interest") shall forthwith cease to be payable to the registered
Holder on the relevant Regular Record Date, and may be paid by the Company at
its election to the Person in whose name this Note is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Company, notice whereof shall be given to the Holder of this
Note not less than ten days prior to such Special Record Date, or may be paid by
the Company at any time in any other lawful manner, all as more fully provided

Agent to make such payments in such funds in accordance with its normal
procedures.  Periodic payments of interest will be made by check mailed to the
address of the Person entitled thereto as it appears in the Security Register as
of the applicable Regular Record Date or, at the option of the Company, by wire
transfer to an account maintained by such Person with a bank located in the
United States.

                               MEDIUM-TERM NOTE

     This Medium-Term Note is one of a duly authorized issue of Securities of
the Company (herein referred to from time to time as the "Securities"), issued
and to be issued in one or more series under an Indenture dated as of January 1,
1995 and as amended by the Supplemental Indenture dated as of May 18, 1995 (as
it may be supplemented or amended from time to time, herein called the
"Indenture") between the Company and Harris Trust and Savings Bank (successor to
NationsBank of Texas, N.A.), as trustee (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights of the Company, the Trustee and the Holders of the Securities
and of the terms upon which the Securities are, and are to be, authenticated and
delivered.  The Medium-Term Notes, Series A (the "Notes") may be issued from
time to time with different maturities, interest rates and redemption
provisions.

     Interest payments for this Note will include interest accrued to but
excluding the Interest Payment Dates.  Interest payments for this Note shall be
computed and paid on the basis of a 360-day year of twelve 30-day months.

     Unless otherwise indicated on the face of this Note, this Note may not be
redeemed prior to Stated Maturity.  If so indicated on the face of this Note,
this Note may be redeemed, at the option of the Company, on and after the
Initial Redemption Date, either in whole or from time to time in part at the
Redemption Price (as defined below), together with interest accrued thereon to
the date of redemption (the "Redemption Date").  Notice of redemption shall be
mailed to the Holders of the Notes designated for redemption at their addresses
as the same shall appear in the Security Register not more than 60 nor less than
30 days prior to the Redemption Date, subject to all the conditions and
provisions of the Indenture.  In the event of any redemption in part, a new Note
for the amount of the unredeemed portion hereof shall be issued in the name of
the Holder hereof upon the surrender hereof.  The "Redemption Price" shall
initially be the Initial Redemption Percentage, shown on the face hereof, of the
principal amount of this Note to be redeemed and shall decline at each
anniversary of the Initial Redemption Date, shown on the face hereof, by the
Annual Redemption Percentage Reduction, if any, shown on the face hereof, of the
principal amount to be redeemed until the Redemption Price is 100% of such
principal amount.

     If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal amount of the
Securities at the time Outstanding of each series to be affected.  The Indenture
also contains provisions permitting the Holders of not less than a majority in
aggregate principal amount of the Outstanding Securities of any such series to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in lieu hereof or in exchange or
substitution hereof, whether or not any notation of such consent or waiver is
made upon this Note.

     As set forth in, and subject to, the provisions of the Indenture, no Holder
of any Note will have any right to institute any proceeding, judicial or
otherwise, with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to the Notes, the Holders of not less
than 25% in principal amount of the Outstanding Notes shall have made written
request to the Trustee to institute such proceeding in respect of such Event of
Default in its own name as Trustee under the Indenture, such Holder or holders
have offered to the Trustee reasonable indemnity against the costs, expenses and
liabilities to be incurred in compliance with such request, the Trustee shall
have failed to institute such proceeding within 60 days of receipt of such
notice, request and offer of indemnity, and the Trustee shall not have received
from the Holders of a majority in principal amount of the Outstanding Notes a
direction inconsistent with such written request during the 60-day period;
provided, however, that such limitations do not apply to a suit instituted by
the Holder for the enforcement of payment of the principal of, premium, if any,
or interest on this Note on or after the respective due date expressed herein.

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

     The Indenture contains provisions for defeasance of (i) the entire
indebtedness of this Note and (ii) certain restrictive covenants upon compliance
by the Company with conditions set forth therein.

     The Notes are issuable only in registered form without coupons and are
represented by either a global certificate registered in the name of a
depositary or in the name of its nominee or by a certificate registered in the
name of the purchaser of such Note or its nominee. The Notes are issuable in
denominations of $1,000 or any amount in excess thereof which is an integral
multiple of $1,000.

     As provided in the Indenture and subject to certain limitations therein set
forth and except as otherwise restricted by a legend printed on the face hereof,
if any, the transfer of this Note may be registered on the Security Register,
upon surrender of this Note for registration of transfer at any office or agency
of the Company in any place where the principal of, premium, if any, and
interest on this Note are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company, the Trustee and the
Security Registrar, duly executed by, the Holder or his attorney duly authorized
in writing, and thereupon one or more new Notes of like aggregate principal
amount of such denominations as are authorized for Notes and of like Stated
Maturity with like terms and conditions will be issued to the designated
transferee or transferees.

     As provided in the Indenture and subject to certain limitations set forth
therein and except as otherwise restricted by a legend printed on the face
hereof, if any, Notes are exchangeable for a like aggregate principal amount of
Notes of such denominations as are authorized for Notes of like Stated Maturity
with like terms and conditions, as requested by the Holder surrendering the
same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. Expenses may
be charged for replacing mutilated, destroyed, lost or stolen Notes provided the
requirements for replacement are satisfied.
