       Section 1.1.  As of the Effective Time, in accordance with Section
1310 and
Article Eight of the Indenture, Section 1301 is hereby amended to read in its
entirety as
follows:

       "Section 1301.  Conversion Privilege and Conversion Price.

             Subject to and upon compliance with the provision of this
Article, at the
       option of the Holder thereof, any Debenture or any portion of the
principal
       amount thereof which is $1,000 or any integral multiple of $1,000 may
be
       converted at the principal amount thereof, or of such portion thereof,
into a cash
       payment equal to $6.70 times the number of shares of Common Stock of
the
       Company (calculated as to each conversion to the nearest 1/100 of a
share) into
       which such Debenture or any portion of the principal amount thereof is
       convertible into, at the conversion price, determined as hereinafter
provided, in
       effect at the time of conversion.  Such conversion right shall expire
at the close of
       business on March 1, 2012.  In case a Debenture or portion thereof is
called for
       redemption, such conversion right in respect of the Debenture or
portion so called
       shall expire at the close of business on the business day prior to the
Redemption
       Date, unless the Company defaults in making the payment due upon
redemption.

             The price at which shares of Common Stock shall be delivered
upon
       conversion (herein called the "conversion price") shall be initially
$40.00 per share
       of Common Stock.  The conversion price shall be adjusted in certain
instances as
       provided in paragraphs (1), (2), (3), (4), (7) and (8) of Section
1304."

Debentures
modified as to reflect the substance of this Supplemental Indenture, but, in
accordance
with Section 906 of the Indenture, Debentures authenticated and delivered
after the
Effective Time shall bear a notation in form approved by the Trustee for the
purpose of
reflecting the provisions of this Supplemental Indenture.
