                                   --------

     The Company has duly authorized the execution and delivery of this Second
Supplemental Indenture and all things necessary to make this Second Supplemental
Indenture a valid agreement of the Company have been done.  This Second
Supplemental Indenture is entered into pursuant to Section 12.1(1)(h) of the

Holders of Securities in any material respect.

     NOW, THEREFORE, in consideration of the above premises, it is mutually
covenanted and agreed, for the equal and proportionate benefit of the Holders of
the Securities, as follows:

1.   The first sentence in the sixth paragraph of the reverse side of the Form
of Security contained in Section 3.2 of the Supplemental Indenture shall be
amended in its entirety and restated to read as follows:

     "Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled, at its option, at any time following the
initial issuance date of the Securities and on or before the close of business
on the date of Maturity, or in case this Security or a portion hereof is called
for redemption or the Holder hereof has exercised its right to require the
Company to repurchase this Security or such portion hereof, then in respect of
this Security until and including, but (unless the Company defaults in making
the payment due upon redemption or repurchase, as the case may be) not after,
the close of business on the Business Day next preceding such Redemption Date or
                             --------------------------------
the Repurchase Date, as the case may be, to convert this Security (or any
portion of the principal amount hereof that is an integral multiple of $1,000,
provided that the unconverted portion of such principal amount is $1,000 or any
integral multiple of $1,000 in excess thereof) into fully paid and nonassessable
shares of Common Stock of the Company at an initial Conversion Rate of 43.9464
shares of Common Stock for each $1,000 principal amount of Securities (or at the
current adjusted Conversion Rate 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, with the conversion notice hereon

                                       1

duly executed and, in case such surrender shall be made during the period from
the close of business on any Record Date next preceding any Interest Payment
Date to the opening of business on such Interest Payment Date (except if this
Security or portion thereof has been called for redemption on a Redemption Date
during the period from such Record Date through the date that is three (3)
Business Days following such Interest Payment Date), also accompanied by payment
in New York Clearing House or other funds 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, to the Company at the Corporate
Trust Office of the Trustee, or at such other office or agency of the Company,
subject to any laws or regulations applicable thereto and subject to the right
of the Company to terminate the appointment of any Conversion Agent (as defined
below) as may be designated by it for such purpose in the Borough of Manhattan,
The City of New York, or at such other offices or agencies as the Company may
designate (each a "Conversion Agent")."

2.   All the provisions of this Second Supplemental Indenture shall be deemed to
be incorporated in, and made a part of, the Indenture; and the Indenture, as
supplemented and amended by this Second Supplemental Indenture, shall be read,
taken and construed as one and the same instrument.

3.   For all purposes of this Second Supplemental Indenture, except as otherwise
defined herein, capitalized terms used in this Second Supplemental Indenture
shall have the meanings ascribed to such terms in the Supplemental Indenture.

4.   This Second Supplemental Indenture may be executed in any number of
counterparts each of which shall be deemed an original; but such counterparts
shall together constitute but one and the same instrument.

5.   The recitals contained herein shall be taken as the statements of the
Company and the Trustee assumes no responsibility for their correctness.  The
Trustee makes no representations as to the validity or sufficiency of this
Second Supplemental Indenture.
