          This Note is one of a duly authorized issue of debt securities (the
"Securities") of the Company, of a series designated as its ____ Notes due
___________ (herein called the "Notes"), limited (except as otherwise provided
in the Indenture) in aggregate principal amount to ____________, issued and to
be issued under the Indenture, to which Indenture and all relevant indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, obligations, duties and immunities thereunder of the Company, the
Trustee, the Bank and the Securityholders and the terms upon which the Notes
are, and are to be, authenticated and delivered. The Securities, of which the
Notes constitute a series, 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 at different rates, may be subject to
different covenants and Events of Default and may otherwise vary as in the
Indenture provided. All capitalized terms not otherwise defined herein shall
have the definitions assigned to them in the Indenture.

          This Note may not be redeemed by the Company prior to Stated Maturity
unless otherwise set forth on the face hereof. Notwithstanding Section 4.03 of
the Indenture, pursuant to Section 4.01 thereof, and if so indicated on the face
of this Note, this Note may be redeemed at the option of the Company on any date
on or after the date set forth on the face hereof in whole or in part in
increments of $1,000, at a redemption price or prices designated on the face
hereof to be redeemed together with interest thereon payable to the date fixed
for redemption. This Note may be so redeemed in whole or in part whether or not
other Notes of the same series are redeemed.

          Notice of redemption by the Company will be given by the Company by
mail to holders of the Notes to be redeemed, not less than 30 nor more than 60
days prior to the date fixed for redemption, all as provided in the Indenture.
The Bank may carry out the responsibilities to be performed by the Trustee
required by Article Four of the Indenture.

     The Company is not required to repurchase Notes from holders prior to
Stated Maturity unless otherwise set forth on the face hereof. If so indicated
on the face hereof, this Note may be repurchased by the Company at the option of
the holder on the dates and at the prices designated thereon, in whole or in
part in increments of $1,000, together with interest payable to the repurchase
date. For book-entry notes, unless otherwise specified on the face of this Note,
holders must deliver written notice to the Bank at least 30, but no more than
60, days prior to the date of repurchase, but no later than 5:00 p.m. New York
City time on

                                       -5-

the last day for giving notice. The written notice must specify the principal
amount to be repurchased and must be signed by a duly authorized officer of the
Depositary participant (signature guaranteed). For definitive notes, unless
otherwise specified on the face of this Note, holders must complete the "Option
to Elect Repayment" on the reverse of this Note and then deliver this Note to
the Bank at least 30, but no more than 45, days prior to the date of repurchase,
but no later than 5:00 p.m. New York City time on the last day for giving
notice. All notices are irrevocable.

          In the event of redemption or repurchase of this Note in part only, a
new Note or Notes of this series, having the same Stated Maturity, optional
redemption or repurchase provisions, Interest Rate and other terms and
provisions of this Note, in authorized denominations in an aggregate principal
amount equal to the unredeemed portion hereof will be issued in the name of the
holder hereof upon the surrender hereof.

          The Notes will not be subject to conversion, amortization or any
sinking fund.

          As provided in the Indenture and subject to certain limitations herein
and therein set forth, the transfer of this Note may be registered on the
register of the Notes, upon surrender of this Note for registration of transfer
at the Bank, or at such other agencies as may be designated pursuant to the
Indenture, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Trustee or the Bank 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 as registered Notes without coupons in
denominations of $1,000 or any amount in excess thereof that is an integral
multiple of $1,000. As provided in the Indenture, and subject to certain
limitations herein and therein set forth, the Notes are exchangeable for a like
aggregate principal amount of Notes of other authorized denominations having the
same interest rate, Stated Maturity, optional redemption or repurchase
provisions, if any, and Original Issue Date, as requested by the Securityholder
surrendering the same.

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

          The Company, the Trustee, the Bank, the Security registrar and any
agent of the Company, the Trustee, the Bank, or the Security registrar may treat
the Securityholder in whose name this Note is registered as the absolute owner
hereof for the purpose of receiving payment as herein provided and for all other
purposes, whether or not this Note is overdue, and neither the

                                       -6-

<PAGE>

Company, the Trustee, the Bank, the Security registrar nor any such agent shall
be affected by notice to the contrary.

          If an Event of Default (as defined in the Indenture) with respect to
the Notes shall occur and be continuing, the principal of all the Notes 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 amendment thereof and the modification of the rights and obligations of the
Company and the rights of the holders of the Securities of any series under the
Indenture at any time by the Company with the consent of the holders of not less
than 66 2/3% in aggregate principal amount of the Securities at the time
Outstanding to be affected (voting as one class). The Indenture also permits the
Company and the Trustee to enter into supplemental indentures without the
consent of the holders of Securities of any series for certain purposes
specified in the Indenture, including the making of such other provisions in
regard to matters arising under the Indenture which shall not adversely affect
the interest of the holders of such Securities. The Indenture also contains
provisions permitting the holders of specified percentages in aggregate
principal amount of the Securities of any series at the time Outstanding, on
behalf of the holders of all the Securities of such series, 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 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 herefor or in lieu hereof whether
or not notation of such consent or waiver is made upon this Note.

          The Indenture provides that no holder of any Security of any series
may enforce any remedy with respect to such series under the Indenture except in
the case of refusal or neglect of the Trustee to act after notice of a
continuing Event of Default and after written request by the holders of not less
than 25% in aggregate principal amount of the Outstanding Securities of such
series and the offer to the Trustee of reasonable indemnity; provided, however,
that such provision shall not prevent the holder hereof from enforcing payment
of the principal of or interest on this Note.

          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.

          No recourse shall be had for the payment of the principal of or the
interest on this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture or any indenture supplemental
thereto, against any incorporator, stockholder, officer or director, as such,
past, present or future, of the Company or any predecessor or successor
corporation, whether by virtue of any constitution,

statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.

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