                                 Reverse of Note

         This Note is one of a duly authorized issue of Securities of the
Company, designated as its 4.50% Convertible Senior Notes Due 2007 (herein
called the "Notes"), all issued or to be issued under and pursuant to an
Indenture dated as of November 25, 2002 (as supplemented by an officers'
certificate dated as of November 25, 2002, the "Indenture"), between the Company
and the Bank of New York (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 Notes.

         The indebtedness evidenced by the Notes is unsecured and unsubordinated
indebtedness of the Company and ranks equally with the Company's other unsecured
and unsubordinated indebtedness.

         No sinking fund is provided for the Notes.

         Redemption at the Option of the Company. The Notes are redeemable as a
whole, or from time to time in part, at any time after December 4, 2005 at the
option of the Company, if the last reported sale price of the Company's Common
Stock is at least 150% of the then effective Conversion Price for at least 20
Trading Days within a period of 30 consecutive Trading Days ending within five
Trading Days of the date of Redemption Notice, at the following redemption
prices (each, a "Redemption Price"), expressed as a percentage of principal
amount for Notes redeemed during the periods set forth below:
                                                                    Redemption
         Period                                                        Price
         --------------------------------------------------------- -------------
         Beginning on December 4, 2005 through November 30, 2006      101.8%
         Beginning on December 1, 2006 through November 30, 2007      100.9%
         At December 1, 2007                                          100.0%

in each case together with accrued and unpaid interest to, but excluding, the
Redemption Date. Accrued and unpaid interest shall be paid to the Holder that
receives the Redemption Price unless the Redemption Date is an Interest Payment
Date, in which case interest shall be paid to the record holder on the
applicable Regular Record Date or Special Record Date.

         Purchase By the Company at the Option of the Holder. At the option of
the Holder and subject to the terms and conditions of the Indenture, the Company
shall become obligated to repurchase the Notes if a Fundamental Change occurs at
any time prior to December 1, 2007 at 100% of the Principal plus accrued and
unpaid interest to, but excluding, the Repurchase Date (the "Repurchase Price"),
which Repurchase Price shall be paid in cash.

         Holders have the right to withdraw any Repurchase Notice by delivering
to the Paying Agent a written notice of withdrawal in accordance with the
provisions of the Indenture.

         If cash sufficient to pay the Repurchase Price of all Notes or portions
thereof to be purchased on a Repurchase Date is deposited with the Paying Agent
on the Business Day

                                        5

<PAGE>

following the Repurchase Date interest will cease to accrue on such Notes (or
portions thereof) immediately after such Repurchase Date and the Holder thereof
shall have no other rights as such (other than the right to receive the
Repurchase Price upon surrender of such Note).

         Conversion. Subject to the provisions of the Indenture, the Holder
hereof has the right, at its option, at any time following the date of issuance
of the Notes and prior to the close of business on the Business Day next
preceding December 1, 2007, to convert the Principal hereof or any portion of
such Principal which is $1,000 or an integral multiple thereof, into that number
of fully paid and non-assessable shares of Common Stock, as said shares shall be
constituted at the date of conversion, obtained by dividing the Principal of
this Note or portion thereof to be converted by the conversion price of $7.37
(the "Conversion Price") as adjusted from time to time as provided in the
Indenture, upon surrender of this Note, together with a Conversion Notice as
provided in the Indenture, to the Company at the office or agency of the Company
maintained for that purpose in the Borough of Manhattan, The City of New York,
or at the option of such Holder, the Corporate Trust Office, and, unless the
shares issuable on conversion are to be issued in the same name as this Note,
duly endorsed by, or accompanied by instruments of transfer in form satisfactory
to the Company duly executed by, the Holder or by his duly authorized attorney.
No adjustment in respect of interest or dividends will be made upon any
conversion; provided, that, if this Note shall be surrendered for conversion
during the period from the close of business on any Regular Record Date for the
payment of interest through the close of business on the Business Day next
preceding the following Interest Payment Date, and has not been called for
redemption on a Redemption Date that occurs during such period, such Note (or
portion thereof being converted) must be accompanied by an amount, in funds
acceptable to the Company, equal to the interest payable on such Interest
Payment Date on the principal amount being converted; provided, however, that no
such payment shall be required if there shall exist at the time of conversion a
default in the payment of interest on the Notes. No fractional shares will be
issued upon any conversion, but an adjustment and payment in cash will be made,
as provided in the Indenture, in respect of any fraction of a share which would
otherwise be issuable upon the surrender of any Notes for conversion. Notes in
respect of which a Holder is exercising its right to require repurchase on a
Repurchase Date may be converted only if such Holder withdraws its election to
exercise such right in accordance with the terms of the Indenture. Any Notes
called for redemption, unless surrendered for conversion by the Holders thereof
on or before the close of business on the Business Day preceding the date fixed
for redemption, may be deemed to be redeemed from such Holders for an amount
equal to the applicable Redemption Price, by one or more investment banks or
other purchasers who may agree with the Company (i) to purchase such Notes from
the Holders thereof and convert them into shares of the Common Stock and (ii) to
make payment for such Notes as aforesaid to the Trustee in trust for the
Holders.

         In the event of a deposit or withdrawal of an interest in this Note,
including an exchange, transfer, repurchase or conversion of this Note in part
only, the Trustee, as custodian of the Depositary, shall make an adjustment on
its records to reflect such deposit or withdrawal in accordance with the rules
and procedures of the Depositary.

         If an Event of Default shall occur and be continuing, the Principal
plus interest accrued through such date on all the Notes may be declared due and
payable in the manner and with the effect provided in the Indenture.

                                        6

         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 Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of not less
than a majority in aggregate principal amount of the Outstanding Notes. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Outstanding Notes, on behalf of
the Holders of all the Notes, 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.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Note shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Notes, the Holders of not less than 25% in aggregate principal amount of the
Outstanding Notes shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity satisfactory to it, and the Trustee shall not have
received from the Holders of a majority in principal amount of Outstanding Notes
a direction inconsistent with such request, and shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer
of indemnity. The foregoing shall not apply to any suit instituted by the Holder
of this Note for the enforcement of any payment of said principal hereof or
interest hereon on or after the respective due dates expressed herein or for the
enforcement of any conversion right.

         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 or Repurchase Price of, and
interest on, this Note at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Note is registrable by the Registrar, upon
presentation of this Note for registration of transfer to the Registrar if the
Registrar's requirements for such transactions are met.

         The Notes are issuable only in registered form in denominations of
$1,000 and any integral multiple of $1,000 above that amount, as provided in the
Indenture and subject to certain limitations therein set forth. Notes are
exchangeable for a like aggregate principal amount of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

         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 cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this

Note be overdue, and neither the Company, the Trustee nor any such agent shall

laws of the State of New York.

         All terms used in this Note which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.
