Securities and the rights, obligations, duties and immunities of the Trustee and
of the Company, and the terms upon which the Securities are and are to be
authenticated and delivered. As provided in the Indenture, 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, may be subject to different covenants and Events of Default and may
otherwise vary as in the Indenture provided or permitted. This Note is one of a
series designated as ________ Notes, Series __, due ____________ limited to
$__________ in aggregate principal amount (the "_______ Notes").

                  2. Interest that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the person in whose
name this Note is registered at the close of business on the Regular Record Date
next preceding such Interest Payment Date. The Regular Record Date, with respect

been originally issued. Notwithstanding the foregoing, any interest that is
payable but not punctually paid or duly provided for on any Interest Payment
Date shall forthwith cease to be payable to the registered owner hereof on such
Regular Record Date, and may be paid to the person in whose name this Note is
registered on the close of business on a Special Record Date established by
notice given by mail, by or on behalf of the Company to such Holder not less
than fifteen days preceding such Special Record Date, such record date to be not
less than ten days preceding the date for payment of such defaulted interest, or
may be paid as more fully provided in the Indenture.


                  3. Payments of interest (other than interest payable at
Maturity) will be made by mailing a check to the Holder at the address of the
Holder appearing on the Securities Register on the applicable record date,

the Borough of Manhattan, The City of New York, or as otherwise provided in the
Indenture.

                  4. If an Event of Default with respect to this Note occurs and
is continuing, the principal of this Note may be declared due and payable in the
manner and with the effect provided in the Indenture.

                  5. 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 Securities under
the Indenture at any time by the Company with the consent of the Holders of not
less than a majority in principal amount of the Securities at the time
Outstanding of all series to be affected thereby (voting as one class). The
Indenture also contains provisions permitting the Holders of a majority in
principal amount of the Securities of any series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and past defaults under the
Indenture and their consequences with respect to such series. In the case of any
such waiver, the Holder of this Note shall be restored to his former position
and rights hereunder, such default shall cease to exist and be deemed to have
been cured and not to have occurred, and any related Event of Default shall be
deemed to have been cured, and not to have occurred 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 thereon.

or in part and are not subject to Article XIV of the Indenture. The ___________
Notes are not entitled to any sinking fund and the provisions of Article XV of
the Indenture are inapplicable thereto.

therein.

                  8. No reference herein to the Indenture and no provision of
this Note or of the Indenture shall affect or impair


                                       3
<Page>

the obligation of the Company, which is unconditional and absolute, to pay the

transfer at the office or agency of the Company to be maintained for that
purpose in The City of New York. Every ___________ Note presented for

Registrar) be duly endorsed, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Securities Registrar duly executed,

one or more new _____________ Notes of authorized denominations and for the same
aggregate principal amount will be issued to the designated transferee or

such _________ Note being redeemed in part.

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

the Indenture with respect hereto, and the Depository or its nominee may be
treated by the Company, the Trustee, and any agent of the Company or the Trustee
as the owner hereof for all purposes whatsoever.


Notwithstanding the foregoing, nothing herein shall impair, as between the
Depository and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depository as the Holder
hereof.

                  12. Unless otherwise defined herein, all terms used in this
Note which are defined in the Indenture shall have the meaning assigned to them
