obligation with respect to the payment of principal shall have been
discharged; provided, however, that if the date hereof is after a record
date specified below with respect to any Interest Payment Date and prior to
such Interest Payment Date, then interest shall be payable only from such
Interest Payment Date (unless the Issue Date is after such record date and

Interest Accrual Date.  In the event that any Interest Payment Date is not a
Business Day, then payment of interest payable on such date will be made on
the next succeeding day which is a Business Day (and without any interest or
other payment in respect of such delay) with the same force and effect as if
made on such Interest Payment Date.  The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in

the Holder on such Regular Record Date and may either 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 Special Record Date for the payment
of such Defaulted Interest to be fixed by the Trustee, notice of which shall
be given to Holders of Securities of this series not less than 10 days prior
to such Special Record Date, or be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Securities of this series may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the
Indenture.

     Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for
that purpose in The City of New York, the State of New York, in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that, at
the option of the Company, interest on this Security may be paid by check
mailed to the address of the person entitled thereto, as such address shall
appear on the Security Register, or by electronic transfer to an account
designated by the person entitled thereto.

entire indebtedness of the Company in respect of this Security, or any
portion of the principal amount thereof, upon compliance with certain

any Security 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 Security.

     As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding

indemnity, and (e) the Trustee shall not have received from the Holders of a
majority in aggregate principal amount of Securities of all series at the
time Outstanding in respect of which an Event of Default shall have occurred
and be continuing a direction inconsistent with such request.  The foregoing
shall not apply to any suit instituted by the Holder of this Security for
the enforcement of any payment of principal hereof or any premium or [,
subject to the extension of interest payment provisions,] interest hereon on
or after the respective due dates expressed herein.
