This Security is
one of a duly authorized issue of Securities of the Company (the “Securities”),
issued and to be issued in one or more series under an Indenture dated as of
November 13, 1996 (as supplemented through the date hereof, the “Indenture”),
between the Company and JPMorgan Chase Bank (formerly known as The Chase
Manhattan Bank), as Trustee (the “Trustee,” which term includes any successor

thereto reference is hereby made for a statement of the respective rights,

Company, the Trustee and the Holders of the Securities and of the terms upon

principal amounts, may provide for re-opening in the future to issue additional
Securities of the series without the consent or approval of the holders of
Outstanding Securities, may mature at different times, may bear interest, if
any, at different rates, may be subject to different redemption provisions, if
any, may be subject to different sinking, purchase or analogous funds, if any,
may be subject to different covenants and Events of Default and may

otherwise vary as
in the Indenture provided or permitted. This Security is one of a series of
Securities designated on the face hereof limited in aggregate principal amount
to U.S. $300,000,000, except that in accordance with the provisions of the
Indenture the series of Securities may be reopened in the future without the
consent of the holders of the then Outstanding Securities to issue additional
Securities of this series.




The Securities of
this series are redeemable, upon not less than 30 nor more than 60 days’ notice
by mail, as a whole or in part, at the option of the Company at any time at the
“Make-Whole Price.”  As used herein, the term “Make-Whole Price” means
an amount equal to the greater of:




(1)
            100% of the
      principal amount of the Securities of this series to be redeemed;
      and




(2)
            as determined
      by an Independent Investment Banker, the sum of the present values of the
      remaining scheduled payments of principal and interest on the Securities
      to be redeemed (not including any portion of such payments of interest
      accrued as of the Redemption Date) discounted back to the Redemption Date
      on a semi-annual basis (assuming a 360-day year consisting of twelve
      30-day months) at the Treasury Rate (as defined below) plus 50 basis
      points.




plus, in the case
of both (1) and (2), accrued and unpaid interest to the Redemption Date, but
interest installments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the
Indenture.  On and after the applicable Redemption Date, interest will
cease to accrue on the Securities of this series to be redeemed, unless a
default is made in payment of the Make-Whole Price.




“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 Securities of this series 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 Securities of this series.




“Comparable
Treasury Price” means, with respect to any Redemption Date, (1) the average of
four Reference Treasury Dealer Quotations for such Redemption Date, after

thereto reference is hereby made for a statement of the respective rights,
limitations of rights, obligations, duties and immunities thereunder 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

A2-4


may be issued in
one or more series, which different series may be issued in various aggregate

Outstanding Securities, may mature at different times, may bear interest, if
any, at different rates, may be subject to different redemption provisions, if
any, may be subject to different sinking, purchase or analogous funds, if any,
may be subject to different covenants and Events of Default and may otherwise
vary as in the Indenture provided or permitted.  This Security is one
of a series of Securities designated on the face hereof limited in aggregate
principal amount to U.S. $300,000,000, except that in accordance with the

issue additional Securities of this series.




The Securities of
this series are redeemable, upon not less than 30 nor more than 60 days’ notice

      by an Independent Investment Banker, the sum of the present values of the
      remaining scheduled payments of principal and interest on the Securities
      to be redeemed (not including any portion of such payments of interest
      accrued as of the Redemption Date) discounted back to the Redemption Date
      on a semi-annual basis (assuming a 360-day year consisting of twelve
      30-day months) at the Treasury Rate (as defined below) plus 50 basis
      points.




plus, in the case
of both (1) and (2), accrued and unpaid interest to the Redemption Date, but
interest installments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the
Indenture.  On and after the applicable Redemption Date, interest will
cease to accrue on the Securities of this series to be redeemed, unless a
default is made in payment of the Make-Whole Price.




“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 Securities of this series 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 Securities of this series.




“Comparable
Treasury Price” means, with respect to any Redemption Date, (1) the average of
four Reference Treasury Dealer Quotations for such Redemption Date, after

Quotations.

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, 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.




“Treasury Rate”
means, with respect to any Redemption Date, (1) the yield, under the heading
which represents the average for the immediately preceding week, appearing in
the most recently published statistical release designated “H.15(519)” or any
successor publication that is published weekly by the Board of Governors of the

amount) equal to the Comparable Treasury Price for such Redemption
Date.  The Treasury Rate shall be calculated on the third Business Day
preceding the Redemption Date.




In the event of
redemption of this Security in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.




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