Company, the Trustee or other Paying Agent and such Person and (b) if such
Person is a Holder of $10,000,000 or more in aggregate principal amount of
Securities of this series such payment may be in immediately available funds by

the Trustee at its Corporate Trust Office in The City of New York not less than
fifteen calendar days prior to the applicable payment date and, unless revoked
by written notice to the Trustee received on or prior to the Regular Record Date
immediately preceding the applicable Interest Payment Date, shall remain in
effect with respect to any further interest payments (other than interest
payments at Maturity) with respect to this Security payable to such Holder.
Payment of the principal of and premium, if any, and interest, if any, on this
Security, as aforesaid, shall be made in such coin or currency of the United
States of America as at the time of payment shall be legal tender for the
payment of public and private debts.

Company (herein called the "Securities"), issued and issuable in one or more
series under an Indenture, dated as of October 1, 2001 (such Indenture as
originally executed and delivered and as supplemented or amended from time to
time thereafter, together with any constituent instruments establishing the
terms of particular Securities, being herein called the "Indenture"), between
the Company and JPMorgan Chase Bank (formerly known as The Chase Manhattan
Bank), as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the
respective rights, limitations of rights, duties and immunities of the Company,
the Guarantor, the Trustee and the Holders of the Securities thereunder and of
the terms and conditions upon which the Securities are, and are to be,

<PAGE>

         If any Interest Payment Date, any Redemption Date or the Stated
Maturity shall not be a Business Day (as hereinafter defined), payment of the
amounts due on this Security on such date may be made on the next succeeding
Business Day, and, if such payment is made or duly provided for on such next
succeeding Business Day, no interest shall accrue on such amounts for the period
from and after such Interest Payment Date, Redemption Date or Stated Maturity,
as the case may be, to such Business Day.

         This Security is subject to redemption at the election of the Company,
in whole at any time or in part from time to time, at a Redemption Price equal
to the greater of:

         (a)      100% of the principal amount of this Security to be so
                  redeemed; or

         (b)      as determined by an Independent Investment Banker, the sum of
                  the present values of the remaining scheduled payments of
                  principal and interest on the principal amount of this
                  Security to be so redeemed (not including any portion of such
                  payments of interest accrued to the date of redemption)
                  discounted to the Redemption Date on a semi-annual basis
                  (assuming a 360-day year consisting of twelve 30-day months)
                  at the Adjusted Treasury Rate, plus 25 basis points,

plus, in either of the above cases, accrued and unpaid interest to the date of
redemption.

         "Adjusted Treasury Rate" means, with respect to any Redemption Date:

          (a)  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 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 Remaining Life, yields for the two published
               maturities most closely corresponding to the Comparable Treasury
               Issue shall be determined and the Adjusted Treasury Rate shall be
               interpolated or extrapolated from such yields on a straight line
               basis, rounding to the nearest month); or

          (b)  if 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 Adjusted Treasury Rate shall be calculated on the third Business Day
preceding the 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 to the Stated Maturity of this Security 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 such Security (the "Remaining
Life").

         "Comparable Treasury Price" means (1) the average of five Reference
Treasury Dealer Quotations for such Redemption Date, after excluding the highest

                                       3

<PAGE>

and lowest Reference Treasury Dealer Quotations, or (2) if the Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such quotations.

         "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by the Company.

         "Reference Treasury Dealer" means:

         (a)   Morgan Stanley & Co. Incorporated and Barclays Capital Inc. and
               their respective successors; provided, however, that if either 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 another Primary Treasury Dealer and

         (b)   any three other Primary Treasury Dealers selected by the Company.

         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Independent Investment Banker, 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 Independent Investment Banker at 5:00
p.m., New York City time, on the third Business Day preceding such Redemption
Date.

         Promptly after the calculation thereof, the Company shall give the
Trustee written notice of the Redemption Price for the foregoing redemption. The
Trustee shall have no responsibility for any such calculation.

         Notice of redemption (other than at the option of the Holder) shall be
given by mail to Holders of Securities, not less than 30 days nor more than 60
days prior to the date fixed for redemption, all as provided in the Indenture.
As provided in the Indenture, notice of redemption at the election of the
Company as aforesaid may state that such redemption shall be conditional upon
the receipt by the applicable Paying Agent or Agents of money sufficient to pay
the principal of and premium, if any, and interest, if any, on this Security on
or prior to the date fixed for such redemption; a notice of redemption so
conditioned shall be of no force or effect if such money is not so received and,
in such event, the Company shall not be required to redeem this Security.

         In the event of redemption of this Security in part only, a new
Security or Securities of this series, of like tenor, representing the
unredeemed portion hereof shall 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 this Security may be declared
due and payable in the manner and with the effect provided in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
Trustee to enter into one or more supplemental indentures for the purpose of
adding any provisions to, or changing in any manner or eliminating any of the
provisions of, the Indenture with the consent of the Holders of not less than a
majority in aggregate principal amount of the Securities of all series then
Outstanding under the Indenture, considered as one class; provided, however,
that if there shall be Securities of more than one series Outstanding under the
Indenture and if a proposed supplemental indenture shall directly affect the
rights of the Holders of Securities of one or more, but less than all, of such
series, then the consent only of the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all series so directly
affected, considered as one class, shall be required; and provided, further,
that if the Securities of any series shall have been issued in more than one

                                       4

<PAGE>

Tranche and if the proposed supplemental indenture shall directly affect the
rights of the Holders of Securities of one or more, but less than all, of such
Tranches, then the consent only of the Holders of a majority in aggregate
principal amount of the Outstanding Securities of all Tranches so directly
affected, considered as one class, shall be required; and provided, further,
that the Indenture permits the Trustee to enter into one or more supplemental
indentures for limited purposes without the consent of any Holders of
