amount as set forth in the attached Schedule of Increases and Decreases) on May
15, 2012, and to pay interest thereon from May 15, 2002 or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually on May 15 and November 15 in each year, commencing November 15,
2002, at the rate of 6.375% per annum, until the principal hereof is paid or
made available for payment. The interest so payable, and punctually paid or duly

Company payment of interest may be made by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register;

                               REVERSE OF SECURITY

         This Note is one of a duly authorized issue of Debt Securities of the
Company (herein called the "Notes"), issued and to be issued in one or more
series under an Indenture, dated as of September 15, 1995 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and JPMorgan Chase Bank (formerly known as The
Chase Manhattan Bank and Chemical Bank), as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), and
reference is hereby made to the Indenture 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 which the Notes
are, and are to be, authenticated and delivered. This Note is one of the series
designated on the face hereof, initially limited in aggregate principal amount
to $200,000,000, subject to certain exceptions referred to in the Indenture. In
addition, the Company may from time to time without the consent of the Holders
of Notes create and issue further Debt Securities having the same terms and
conditions as the Notes in all respects (or in all respects except for the issue
date and issue price) and so that such further issue shall be consolidated and
form a single series with the outstanding Debt Securities of this series
(including the Notes) or upon such terms as the Company may determine at the
time of their issue. References herein to the Notes include (unless the context
requires otherwise) any other Debt Securities issued as described in this
paragraph and forming a single series with the Notes.

         The Notes are subject to redemption, in whole or from time to time in
part, at the Company's option on any date at a redemption price equal to the
greater of: (1) 100% of the principal amount of the Notes to be redeemed, and
(2) the sum of the present values of the remaining scheduled payments of
principal and interest on the Notes to be redeemed (exclusive of interest
accrued to the applicable redemption date) discounted to that redemption date on
a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Rate plus 20 basis points, plus, in the case of both clause (1)
and clause (2) above, accrued and unpaid interest on the principal amount of the
Notes being redeemed to that redemption date. Notwithstanding the foregoing,
payments of interest on the Notes that are due and payable on or prior to a date
fixed for redemption of Notes will be payable to the Holders of those Notes
registered as such at the close of business on the relevant Regular Record Dates
for the Notes in accordance with the terms and provisions of the Indenture.

"Treasury Rate" means, with respect to any redemption date for the Notes, (1)
the yield, under the heading that represents the average for the immediately
preceding week, appearing in the most recently published statistical release
designated "H.15 (519)" or any successor publication which is published weekly
by the Board of Governors of the Federal Reserve System and which establishes
yields on actively traded United States Treasury securities adjusted to constant
maturity under the caption "Treasury Constant Maturities," for the maturity
corresponding to the Comparable Treasury Issue (if no maturity is within three
months before or after the Final Maturity Date for the Notes, yields for the two
published maturities most closely corresponding to the Comparable Treasury Issue
shall be determined and the Treasury Rate shall be interpolated or extrapolated
from such yields on a straight line basis, rounding to the nearest month), or
(2) if


                                       5
<PAGE>

such release (or any successor release) is not published during the week
preceding the calculation date or does not contain such yields, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, calculated using 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. The Treasury Rate shall be calculated
on the third business day preceding the applicable redemption date. As used in
the immediately preceding sentence and in the definition of "Reference Treasury
Dealer Quotations" below, the term "business day" means any day that is not a
Saturday, Sunday or other day on which commercial banks in New York City are
authorized or required by law to remain closed.

"Comparable Treasury Issue" means, with respect to any redemption date for the
Notes, the United States Treasury security selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the
Notes to be 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 the Notes to be
redeemed.

"Comparable Treasury Price" means, with respect to any redemption date for the
Notes, (1) the average of four Reference Treasury Dealer Quotations 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.

"Final Maturity Date" means May 15, 2012.

"Independent Investment Banker" means, with respect to any redemption date for
the Notes, J.P. Morgan Securities Inc. and its successors, or, if such firm or
the successors, if any, to such firm, as the case may be, are unwilling or
unable to select the Comparable Treasury Issue, an independent investment
banking institution of national standing appointed by the Trustee after
consultation with the Company.

"Reference Treasury Dealers" means, with respect to any redemption date for the
Securities, J.P. Morgan Securities Inc. and three additional primary U.S.
Government securities dealers in New York City (each a "Primary Treasury
Dealer") selected by the Trustee after consultation with the Company, and their
respective successors (provided, however, that if any such firm or any such
successor, as the case may be, shall cease to be a primary U.S. Government
securities dealer in New York City, the Trustee, after consultation with the
Company, shall substitute therefor another Primary Treasury Dealer).

"Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date for the Notes, 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 to the Trustee by that Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third business day preceding that redemption date.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to the Holders of the Notes to be
redeemed at the Holders' registered addresses. If less than all of the Notes are
to be redeemed at the Company's option, the Trustee


                                       6
<PAGE>

will select, in a manner it deems fair and appropriate, the Notes, or portions
of the Notes, to be redeemed.

         In the event of redemption of this Note in part only, a new Note or
Notes for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

         The Company shall not be required (i) to register the transfer of or
exchange any Notes during a period beginning at the opening of business 15 days
before the day of the transmission of a notice of redemption of Notes selected
for redemption and ending at the close of business on the day of such
transmission, or (ii) to register the transfer of or exchange any Notes so
selected for redemption in whole or in part, except the unredeemed portion of
any Notes being redeemed in part.

         If an Event of Default with respect to 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 Notes are not subject to any sinking fund and are not subject to
redemption by the Holders thereof prior to maturity.

         The Indenture contains provisions whereby (i) the Company may be
discharged from its obligations with respect to the Notes (subject to certain
exemptions) or (ii) the Company may be released from its obligation under
specified covenants and agreements in the Indenture, in each case if the Company
irrevocably deposits with the Trustee money or U.S. Government Obligations
sufficient to pay and discharge the entire indebtedness on all Notes of this
series, and satisfies certain other conditions, all as more fully 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 Notes 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 Outstanding Notes. The Indenture also contains
provisions permitting the Holders of not less than specified percentages in
aggregate principal amount of the Outstanding Notes, on behalf of the Holders of
all the Notes, 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 or on behalf of 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 exchange
hereof or in lieu hereof whether 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 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, and offered reasonable
indemnity, to the Trustee to institute such proceeding as trustee, and the
Trustee shall


                                       7
<PAGE>

not have received from the Holders of a majority in principal amount of the
Outstanding Notes a direction inconsistent with such request and shall have
failed to institute such proceeding within 60 days; provided however, that such
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal of or interest on this Note on or after
the respective due dates expressed herein.

         No reference herein to the Indenture and no provision 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 and interest on this Note at
the times, place, and rate, and in the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Note is registerable on the Security Register of
the Company, upon surrender of this Note for registration of transfer at the
Corporate Trust Office of the Trustee maintained for such purpose in New York,
New York, or at such other office or agency as the Company may designate, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Notes of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

         The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Notes are
exchangeable for a like aggregate principal amount of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

         No service charge shall be made for any registration of transfer or
exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

         Prior to the time of due presentment of this Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Note is registered as the absolute owner
hereof for all purposes, whether or not this Note be overdue, and none of the
Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         If at any time, (i) the Depositary is at any time unwilling or unable
to continue as Depositary and a successor Depositary is not appointed by the
Company within 90 days after the Company becomes aware of such condition, (ii)
the Company determines that the Notes shall no longer be represented by a Global
Note or Global Notes or (iii) an Event of Default with respect to the Notes
shall have occurred and be continuing, then the Company will execute and the
Trustee will authenticate and deliver Registered Notes in definitive registered
form, in authorized denominations, and in an aggregate principal amount equal to
the principal amount of this Note in exchange for this Note. Such Notes in
definitive registered form shall be registered in such names and issued in such
authorized denominations as the Depositary, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee. The
Trustee shall deliver such Notes to the Persons in whose names such Notes are so
registered.

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

         Unless the certificate of authentication hereon has been duly executed
by or on behalf of JPMorgan Chase Bank, the Trustee under the Indenture, or its
successor thereunder, by the manual signature of one of its authorized officers,
this Note shall not be entitled to any benefit under the Indenture, or be valid
or obligatory for any purpose.

         This Note shall be governed by, and construed in accordance with, the
laws of the State of New York.
