                                       -2-


This Debenture is one of a duly authorized series of an issue of unsecured debt
securities of the Company designated as its 4.70% Debentures, Series 2004 C
(hereinafter called the "Debentures"), issued and to be issued under an
Indenture dated as of December 1, 1990 between the Company and JPMorgan Chase
Bank (formerly The Chase Manhattan Bank (successor to The Chase Manhattan Bank
(National Association))), Trustee (hereinafter called the "Trustee", which term
includes any successor trustee under the Indenture), as amended and supplemented
by the First Supplemental Indenture, dated as of March 6, 1996, between the
Company and the Trustee (hereinafter called the "Indenture"). Reference is made
to the Indenture and any supplemental indenture thereto for the provisions
relating, among other things, to the respective rights of the Company, the
Trustee and the holders of the Debentures, and the terms on which the Debentures
are, and are to be, authenticated and delivered.

         The Company may redeem the Debentures in whole or in part, at its
option at any time, at a redemption price equal to the greater of (1) 100% of
the principal amount of the Debentures being redeemed or (2) the sum of the
present values of the remaining scheduled payments of principal and interest
thereon (exclusive of interest accrued to the date of redemption) discounted to
the redemption date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as defined below) plus 10 basis
points, plus, in either case, accrued interest on the principal amount being
redeemed to the redemption date.

         "Comparable Treasury Issue" means the United States Treasury security
or securities selected by an Independent Investment Banker (as defined below) as
having an actual or interpolated maturity comparable to the remaining term of
the Debentures being redeemed 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 such
Debentures.

         "Comparable Treasury Price" means, with respect to any redemption date,
(1) the average of the Reference Treasury Dealer Quotations (as defined below)
for such redemption date, after excluding the highest and lowest such Reference
Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such
Reference Treasury Dealer Quotations, the average of all such quotations.

         "Independent Investment Banker" means one of the Reference Treasury
Dealers (as defined below) appointed by the Trustee after consultation with the
Company.

         "Reference Treasury Dealer" means each of HSBC Securities (USA) Inc.
and J.P. Morgan Securities Inc., their respective successors, and two other
primary U.S. Government securities dealers in The City of New York (a "Primary
Treasury Dealer") selected by the Company. If any Reference Treasury Dealer
shall cease to be a Primary Treasury Dealer, the Company will substitute another
Primary Treasury Dealer for that dealer.

         "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 3:30 p.m. New York
time on the third business day preceeding such redemption date.







                                       -3-

         "Treasury Rate" means, with respect to any redemption date, the rate
per annum equal to the semiannual equivalent yield to maturity or interpolated
(on a day count basis) 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.

         Unless the Company defaults in payment of the redemption price, on and
after the redemption date interest will cease to accrue on the Debentures or
portions thereof called for redemption.

         If an Event of Default (as defined in the Indenture) shall have
occurred and be continuing with respect to the Debentures, the principal hereof
may be declared, and upon such declaration shall become, due and payable, in the
manner, with such effect and subject to the conditions provided in the
Indenture. Any such declaration may be rescinded by holders of a majority in
principal amount of the outstanding Debentures if all Events of Default with
respect to the Debentures (other than the non-payment of principal of the
Debentures which shall have become due by such declaration) shall have been
remedied.

         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 the Debentures at the time outstanding, evidenced
as in the Indenture provided, to execute supplemental indentures adding any
provisions to the Indenture or to any supplemental indenture with respect to the
Debentures, or modifying in any manner the rights of the holders of the
Debentures; provided, however, that no such supplemental indenture shall (i)
extend the maturity of any Debenture, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or make the
principal thereof, or interest thereon, payable in any coin or currency other
than that in the Debentures provided, without the consent of the holder of each
Debenture so affected, or (ii) reduce the aforesaid principal amount of
Debentures, the holders of which are required to consent to any such
supplemental indenture without the consent of the holders of all Debentures then
outstanding.

         The Debentures are issuable as registered Debentures only, in the
denomination of $1000 and any integral multiples of $1000 approved by the
Company, such approval to be evidenced by the execution thereof.

         This Debenture is transferable by the registered holder hereof in
person or by his attorney duly authorized in writing on the books of the Company
at the office or agency to be maintained by the Company for that purpose, but
only in the manner, subject to the limitations and upon payment of any tax or
governmental charge for which the Company may require reimbursement as provided
in the Indenture, and upon surrender and cancellation of this Debenture. Upon
any registration of transfer, a new registered Debenture or Debentures, of
authorized denomination or denominations, and in the same aggregate principal
amount, will be issued to the transferee in exchange therefor.

         The Company, the Trustee, any paying agent and any Security registrar
may deem and treat the registered holder hereof as the absolute owner of this
Debenture (whether or not this Debenture shall be overdue and notwithstanding
any notations of ownership or other writing hereon made by anyone other than the
Security registrar) for the purpose of receiving payment of or on account of the
principal hereof and interest due hereon as herein provided and for all other
purposes, and neither the Company nor the Trustee nor any paying agent nor any
Security registrar shall be affected by any notice to the contrary.


         No recourse shall be had for the payment of the principal of or
interest on this Debenture, 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 or against any past, present or
future stockholder, officer or member of the Board of Directors, as such, of the
Company, 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.








                                       -4-
