of a 360-day year of twelve 30-day months. If any Interest Payment Date or the

payment was due and no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date or the maturity date, as the
case may be, to such next Business Day.] The interest so payable and punctually
paid or duly provided for on any Interest Payment Date will, as provided in such
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the regular
record date for such interest, which shall be ______________ or ______________

by virtue or having been such holder, and may be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on a subsequent special record date (which shall be at least
10 days before the payment date) for the payment of such defaulted interest to
be fixed by the Company, notice whereof shall be given to the Holders of
Securities of this series not less than 10 days prior to such Special Record
Date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be

interest shall be legally enforceable), which shall accrue from the date of such
default in payment to the date payment of such principal has been made or duly
provided for. Interest on any overdue principal shall be payable on demand. Any
such interest on any overdue principal that is not so paid on demand shall bear
interest at the rate of ___% per annum (to the extent that the payment of such

be paid by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register;] [If

[successor] depository may be made by wire transfer to the account designated by
[DTC or] such [successor] depository in writing].

        This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of __________, 20__ (herein called, together
with all indentures supplemental thereto, the "Indenture"), between the Company
and ___________________, 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 statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered. This
Security is one of the series designated on the face hereof [, initially limited
(subject to exceptions provided in the Indenture) to the aggregate principal
amount of $__________].

        Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled, at his option, at any time on or before the
close of business on _________ __, _____, or in case this Security or a portion
hereof is called for redemption, then in respect of this Security or such
portion hereof until and including, but (unless the Company defaults in making
the payment due upon redemption) not after, the close of business on the
Business Day immediately preceding the Redemption Date, to convert this Security
(or any portion of the principal amount hereof which is $1,000 or an integral
multiple thereof or in the case of Bearer Securities $5,000 or an integral
multiple of $5,000), at the principal amount hereof, or of such portion, into
fully paid and non-assessable shares (calculated as to each conversion to the
nearest 1/100 of a share) of Common Stock of the Company at a conversion price
equal to $______ aggregate principal amount of Securities for each share of
Common Stock (or at the current adjusted conversion price if an adjustment has
been made as provided in the Indenture) by surrender of this Security, duly
endorsed or assigned to the Company or in blank, to the Company at its office or
agency in _______________, accompanied by written notice to the Company that the
Holder hereof elects to convert this Security, or if less than the entire
principal amount hereof is to be converted, the portion hereof to be converted
(in the case of Bearer Securities, any Bearer Security surrendered for
conversion must be accompanied by all Coupons maturing subsequent to the date of
surrender of such Bearer Security for conversion or the amount of any such
missing Coupons will be deducted from the amount due on such Security used to
determine the amount of shares of Common Stock such Bearer Security may be
converted into), and, in case such surrender shall be made during the period
from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date
(unless this Security or the portion thereof being converted has been called for
redemption on a Redemption Date such that the conversion right of this Security
would terminate between such Regular Record Date and the close of business on
such Interest Payment Date), also accompanied by payment in funds reasonably
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of this Security then being
converted (with similar provision to be made for Bearer Securities). In case
surrender of this Security for conversion shall be made during the period from
the close of business on any Regular Record Date next preceding any Interest
Payment Date to the opening of business on such Interest Payment Date and if
this Security or portion hereof has been called for redemption on a Redemption
Date with the consequence that the conversion right of this Security would
terminate between such Regular Record Date and the close of business on such
Interest Payment Date, then the Holder of this Security will be entitled to
receive the interest accruing hereon from the Interest Payment Date next
preceding the date of such conversion to



                                      -3-
<PAGE>

such succeeding Interest Payment Date and shall not be required to pay such
interest upon surrender of this Security for conversion. Subject to the
aforesaid requirement for payment and, in the case of a conversion after the
Regular Record Date next preceding any Interest Payment Date and on or before
such Interest Payment Date, to the right of the Holder of this Security (or any
Predecessor Security) of record at such Regular Record Date to receive an
installment of interest (with certain exceptions provided in the Indenture), no
payment or adjustment is to be made on conversion for interest accrued hereon or
for dividends on the Common Stock issued on conversion. No fractions of shares
or scrip representing fractions of shares will be issued on conversion, but
instead of any fractional interest the Company shall pay a cash adjustment as
provided in the Indenture. The conversion price is subject to adjustment as
provided in the Indenture. In addition, the Indenture provides that in case of
certain consolidations or mergers to which the Company is a party or the
transfer of substantially all of the assets of the Company, the Indenture shall
be amended, without the consent of any Holders of Securities, so that this
Security, if then outstanding, will be convertible thereafter, during the period
this Security shall be convertible as specified above, only into the kind and
amount of securities, cash and other property receivable upon the consolidation,
merger or transfer or conveyance by a holder of the number of shares of Common
Stock into which this Security might have been converted immediately prior to
such consolidation, merger or transfer or conveyance (assuming such holder of
Common Stock failed to exercise any rights of election and received per share
the kind and amount received per share by a plurality of nonelecting shares).

        [If the Security is not an Original Issue Discount Security, insert --
If an Event of Default with respect to the Securities shall occur and be
continuing, the principal of the Securities may be declared due and payable in
the manner and with the effect provided in the Indenture.]

Indenture. Such amount shall be equal to [insert formula for determining the
amount]. Upon payment (i) of the amount of principal so declared due and payable
and (ii) of interest on any overdue principal, premium and interest (in each
case to the extent that the payment of such interest shall be legally
enforceable), all of the Company's obligations in respect of the payment of the
principal of and premium and interest, if any, on the Securities of this series
shall terminate.]
