                             6 7/8% Notes due 2006

"Company", which term includes any successor corporation under the Indenture
referred to below), for value received, hereby promises to pay to Cede & Co. or
registered assigns, the principal sum of One Hundred Fifty Million Dollars
($150,000,000) on November 15, 2006, and to pay interest thereon from November
25, 1996 or from the most recent date to which interest has been paid or duly
provided for, semiannually on May 15 and November 15 in each year (each, an
"Interest Payment Date"), commencing May 15, 1997, at the rate of 6 7/8 percent
per annum, until the principal hereof is paid or duly made available for
payment.  Interest on this Note shall be calculated on the basis of a 360-day
year consisting of twelve 30-day months.  The interest so payable and
punctually paid or duly provided for on any Interest Payment Date will, as
provided in such Indenture, be paid to the Person in whose name this Note (or

Interest Payment Date.  Any such interest which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the registered Holder hereof on the relevant
Regular Record Date by virtue of having been such Holder, and may be paid to
the Person in whose name this Note (or one or more Predecessor Securities) 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 Holders of Notes of this series not less than 10 days prior to
such Special Record Date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the
Notes may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in such Indenture.

  Payment of the principal of and the interest on this Note will be made at the
office or agency of the Company maintained for that purpose in The Borough of
Manhattan, The City of New York, in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that, at the option of the Company, interest
may be paid by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register; provided, further, that
payment to DTC or any successor depository may be made by wire transfer to the
account designated by DTC or such successor depository in writing.

  This Note is one of a duly authorized issue of securities of the Company
(herein called the "Notes") issued and to be issued in one or more series under
an Indenture dated as of November 1, 1996 (herein called, together with all

indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Notes, and of the terms upon

provided in the Indenture) to the aggregate principal amount specified in the
Officers' Certificate dated November 25, 1996 establishing the terms of the

binding upon such Holder and upon all future Holders of this Note and of any
Notes issued upon the registration of transfer hereof or in exchange herefor or
in lieu hereof, whether or not notation of such consent or waiver is made upon

aggregate principal amount, will be issued to the designated transferee or

denominations specified in the Officers' Certificate dated November 25, 1996

the Indenture.
