                              7-1/2% NOTE DUE 2007

     This Note is one of a duly authorized issue of Notes of the Company known
as its 7-1/2% Notes due 2007 (herein called the "Notes"), limited to the
aggregate principal amount of $100,000,000, all issued under and equally
entitled to the benefits of an Indenture (herein, together with any amendments
and supplements thereto, including without limitation the form and terms of
Securities issued pursuant thereto, called the "Indenture"), dated as of
November 1, 1996, executed by the Company to The Chase Manhattan Bank (herein,
together with any successor thereto, called the "Trustee"), as Trustee, to
which Indenture reference is hereby made for a statement of the rights
thereunder of the Trustee and of the registered holders of the Notes and of the
duties thereunder of the Trustee and the Company.

     The Notes will be redeemable as a whole or in part, at the option of the
Company at any time, at a redemption price equal to the greater of (i) 100% of
their principal amount and (ii) the sum of the present values of the  remaining
scheduled payments of principal and interest thereon discounted to the date of
redemption on a semiannual basis (assuming a 360-day year consisting of twelve
30-day months) at the Treasury Yield plus 10 basis points, plus accrued
interest to the date of redemption.

     "Treasury Yield" means, with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed 
as a percentage of its principal amount) equal to the Comparable Treasury Price
for such redemption date.

     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
term of the Notes.  "Independent Investment Banker" means Merrill Lynch & Co.
or, if such firm is unwilling or unable to select the Comparable Treasury
Issue, an independent investment banking institution of national standing
appointed by the Trustee.

     "Comparable Treasury Price " means, with respect to any redemption date,
(i) the average of the  Reference Treasury Dealer Quotations for such
redemption date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (ii) if the Trustee obtains fewer than four such
Reference Treasury 

   5



                                      4

Dealer Quotations, the average of all such Quotations. "Reference Treasury 
Dealer Quotations" means, with respect to each Reference Treasury Dealer
and any redemption date, the average, as determined by the Trustee, of the bid
and asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Trustee by such
Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such
redemption date.

     "Reference Treasury Dealer" means each of Merrill Lynch & Co., J.P. Morgan
Securities Inc., BancAmerica Securities, Inc., Chase Securities Inc. and
NationsBanc Capital Markets, Inc.; provided  however, that if any of the
foregoing shall cease to be a primary U.S. Government securities dealer in New
York City (a "Primary Treasury Dealer "), the Company shall substitute therefor
another Primary Treasury dealer.

     Holders of Notes to be redeemed will receive notice thereof by first-class
mail at least 30 and not more than 60 days prior to the date fixed for
redemption.

     The Indenture permits the Company to issue unsecured debentures, notes
and/or other evidences of indebtedness in one or more series ("Securities") up
to such principal amount or amounts as may be authorized in accordance with the
terms of the Indenture.

     To the extent permitted by, and as provided in, the Indenture,
modifications or alterations of the Indenture and of the rights and obligations
of the Company and of the holders of the Notes may be made with the consent of
the Company and with the consent of the holders of not less than a majority in
principal amount of the Securities of all series then outstanding under the
Indenture (treated as a single class) which are affected by the modification or
amendment thereto; provided, however, that without the consent of the holder
hereof no such modification or alteration shall be made which will affect the
terms of payment of the principal of or interest on this Note.

     In case a default, as defined in the Indenture, shall occur, the principal
of all the Notes at any such time outstanding under the Indenture may be
declared or may become due and payable, upon the conditions and in the manner
and with the effect provided in the Indenture.  The Indenture provides that
such declaration may in certain events be waived by the holders of a majority
in principal amount of the Notes outstanding in the case of payment defaults on
the Notes and in certain other events by the holders of a majority in principal
amount of the Securities of all series then outstanding under the Indenture 
(treated as a single class) which are affected thereby.

     The Indenture provides that no holder of any Note may enforce any remedy
under the Indenture except in the case of refusal or neglect of the Trustee to
act after notice of default and after request by the holders of a majority in
principal amount of the outstanding Notes in certain events (and in certain
other events by the holders of a majority in principal amount of the Securities
of all series then outstanding under the Indenture, treated as a single class,
which are affected thereby) and the offer to the Trustee of security and
indemnity satisfactory to it; provided, however, that such provision shall not
prevent the holder hereof from enforcing payment of the principal of or
interest on this Note.

     Unless this certificate is presented by an authorized representative of a
Depositary to the Issuer or its agent for registration of transfer, exchange or
payment, and any certificate issued is registered in the name of the nominee of
such Depositary or such other name as requested by an authorized representative
of such Depositary and any payment is made to the nominee of such Depositary,
ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
PERSON IS WRONGFUL since the registered owner hereof, the nominee, has an
interest herein.

     The Company, the Trustee, any paying agent and any Registrar of the Notes
may deem and treat the person in whose name this Note is registered as the
absolute owner hereof for all purposes whatsoever, and neither the Company nor
the Trustee nor any paying agent nor any Registrar of the Notes shall be
affected by any notice to the contrary.

                                      5

     No recourse shall be had for the payment of the principal of or the
interest on, this Note, or for any claim based hereon or on the Indenture,
against any incorporator or against any stockholder, director or officer, as
such, past, present or future, of the Company, or of any predecessor or
successor corporation, either directly or through the Company or any such
predecessor or 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, whether at common law, in equity, by any
constitution, statute or otherwise, of incorporators, stockholders, directors
or officers being released by every owner hereof by the acceptance of this Note
and as part of the consideration for the issue hereof, and being likewise
released by the terms of the Indenture; provided, however, that nothing herein
or in the Indenture contained shall be taken to prevent recourse to and the
enforcement of the liability, if any, of any stockholder or subscriber to
capital stock of the Company upon or in respect of shares of capital stock not
fully paid up.

     All terms used in this Note which are defined in the Indenture shall have
the meanings assigned to them in the Indenture.
