                            [Sinking Fund Debenture]
                                    Due ____

            This [Note] [Sinking Fund Debenture] is one of a duly authorized
issue of debentures, notes, bonds or other evidences of indebtedness of the
Company (hereinafter called the "Securities") of the series hereinafter
specified, all issued or to be issued under and pursuant to a senior indenture
dated as of June 1, 2001 (herein called the "Indenture"), duly executed and
delivered by the Company to The Chase Manhattan Bank, as trustee (herein called
the "Trustee"), to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and
the Holders of the Securities. The Securities may be issued in one or more
series, which different series may be issued in various aggregate principal
amounts, 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) and may
otherwise vary as in the Indenture provided. This [Note] [Debenture] is one of a
series designated as the ___% [Notes] [Sinking Fund Debentures] Due ___ of the
Company, limited in aggregate principal amount to $________.

            Interest will be computed on the basis of a 360-day year of twelve
30-day months. The Company shall pay interest on overdue Principal and, to the
extent lawful, on overdue installments of interest at the rate per annum borne
by this [Note] [Debenture]. If a payment date is not a Business Day as defined
in the Indenture at a place of payment, payment may be made at that place on the
next succeeding day that is a Business Day, and no interest shall accrue for the
intervening period.

            In case an Event of Default (as defined in the Indenture) with
respect to the ___% [Notes] [Sinking Fund Debentures] Due ____ shall have
occurred and be continuing, the Principal hereof and the interest accrued
hereon, if any, may be declared, and upon such declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions provided
in the Indenture.

            The Indenture contains provisions which provide that, without prior
notice to any Holders, the Company and the Trustee may amend the Indenture and
the Securities of any series with the written consent of the Holders of a
majority in principal amount of the outstanding Securities of all series
affected by such amendment (all such series voting as one class), and the
Holders of a majority in principal amount of the outstanding Securities of all
series affected thereby (all such series voting as one class) by written notice
to the Trustee may waive future compliance by the Company with any provision of
the Indenture or the Securities of such series; provided that, without the
consent of each Holder of the Securities of each series affected thereby, an
amendment or waiver, including a waiver of past defaults, may not: (i) extend
the stated maturity of the Principal of, or any sinking fund obligation or any
installment of interest on, such Holder's Security, or reduce the principal
amount thereof or the rate of interest thereon

                                       4
<PAGE>

(including any amount in respect of original issue discount), or any premium
payable with respect thereto, or adversely affect the rights of such Holder
under any mandatory redemption or repurchase provision or any right of
redemption or repurchase at the option of such Holder, or reduce the amount of
the Principal of an Original Issue Discount Security that would be due and
payable upon an acceleration of the maturity thereof or the amount thereof
provable in bankruptcy, or change any place of payment where, or the currency in
which, any Security of such series or any premium or the interest thereon is
payable, or impair the right to institute suit for the enforcement of any such
payment on or after the due date therefor; (ii) reduce the percentage in
principal amount of outstanding Securities of the relevant series the consent of
whose Holders is required for any such supplemental indenture, for any waiver of
compliance with certain provisions of the Indenture or certain Defaults and
their consequences provided for in the Indenture; (iii) waive a Default in the
payment of Principal of or interest on any Security of such Holder; or (iv)
modify any of the provisions of the Indenture governing supplemental indentures
with the consent of Securityholders except to increase any such percentage or to
provide that certain other provisions of the Indenture cannot be modified or
waived without the consent of the Holder of each outstanding Security affected
thereby.

            It is also provided in the Indenture that, subject to certain
conditions, the Holders of at least a majority in principal amount (or, if any
Securities are Original Issue Discount Securities, such portion of the Principal
as is then accelerable) of the outstanding Securities of all series affected
(voting as a single class), by notice to the Trustee, may waive an existing
Default or Event of Default with respect to the Securities of such series and
its consequences, except a Default in the payment of Principal of or interest on
any Security or in respect of a covenant or provision of the Indenture which
cannot be modified or amended without the consent of the Holder of each
outstanding Security affected. Upon any such waiver, such Default shall cease to
exist, and any Event of Default with respect to the Securities of such series
arising therefrom shall be deemed to have been cured, for every purpose of the
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereto.

            The Indenture provides that a series of Securities may include one
or more tranches (each a "tranche") of Securities, including Securities issued
in a Periodic Offering. The Securities of different tranches may have one or
more different terms, including authentication dates and public offering prices,
but all the Securities within each such tranche shall have identical terms,
including authentication date and public offering price. Notwithstanding any
other provision of the Indenture, subject to certain exceptions, with respect to
sections of the Indenture concerning the execution, authentication and terms of
the Securities, redemption of the Securities, Events of Default of the
Securities, defeasance of the Securities and amendment of the Indenture, if any
series of Securities includes more than one tranche, all provisions of such
sections applicable to any series of Securities shall be deemed equally
applicable to each tranche of any series of Securities in the same manner as
though originally designated a series unless otherwise provided with respect to
such series or tranche pursuant to a board resolution or a supplemental
indenture establishing such series or tranche.

            No reference herein to the Indenture and no provision of this [Note]
[Debenture] or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the Principal of and any
premium and interest on this [Note] [Debenture] in

                                       5

or currency herein prescribed.

[Note] [Debenture] (whether or not this [Note] [Debenture] shall be overdue and

subject to the provisions hereof, interest hereon, and for all other purposes,
and neither the Company nor the Trustee nor any agent of the Company or the
Trustee shall be affected by any notice to the contrary.

contained in the Indenture or any indenture supplemental thereto or in any
[Note] [Debenture], or because of any indebtedness evidenced thereby, shall be
had against any incorporator as such, or against any past, present or future

liability being expressly waived and released by the acceptance hereof and as

compliance with certain provisions of the Indenture or certain Defaults and
their consequences provided for in the Indenture; (iii) waive a Default in the
payment of Principal of or interest on any Security of such Holder; or (iv)
modify any of the provisions of the Indenture governing supplemental indentures
with the consent of Securityholders except to increase any such percentage or to
provide that certain other provisions of the Indenture cannot be modified or
waived without the consent of the Holder of each outstanding Security affected
thereby.

            It is also provided in the Indenture that, subject to certain
conditions, the Holders of at least a majority in principal amount (or, if any
Securities are Original Issue Discount Securities, such portion of the Principal
as is then accelerable) of the outstanding Securities of all series affected
(voting as a single class), by notice to the Trustee, may waive an existing
Default or Event of Default with respect to the Securities of such series and
its consequences, except a Default in the payment of Principal of or interest on
any Security or in respect of a covenant or provision of the Indenture which
cannot be modified or amended without the consent of the Holder of each
outstanding Security affected. Upon any such waiver, such Default shall cease to
exist, and any Event of Default with respect to the Securities of such series
arising therefrom shall be deemed to have been cured, for every purpose of the
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereto.

            The Indenture provides that a series of Securities may include one
or more tranches (each a "tranche") of Securities, including Securities issued
in a Periodic Offering. The Securities of different tranches may have one or
more different terms, including authentication dates and public offering prices,
but all the Securities within each such tranche shall have identical terms,
including authentication date and public offering price. Notwithstanding any
other provision of the Indenture, subject to certain exceptions, with respect to
sections of the Indenture concerning the execution, authentication and terms of
the Securities, redemption of the Securities, Events of Default of the
Securities, defeasance of the Securities and amendment of the Indenture, if any
series of Securities includes more than one tranche, all provisions of such
sections applicable to any series of Securities shall be deemed equally
applicable to each tranche of any series of Securities in the same manner as
though originally designated a series unless otherwise provided with respect to
such series or tranche pursuant to a board resolution or a supplemental
indenture establishing such series or tranche.
