* Less than one percent (1%).
(1) Assumes conversion of all of the holder's LYONs at a conversion rate of
10.3014 common shares per $1,000 principal amount at maturity of the LYONs.
This conversion rate is subject to adjustment, however, as described under
"Description of the LYONs--Conversion Rights--Conversion Rate and Delivery
of Common Shares." As a result, the number of common shares issuable upon
conversion of the LYONs may increase or decrease in the future. Does not
include common shares that may be issued by us upon purchase of LYONs by us
at the option of the holder.
(2) Calculated based on Rule 13d-3(d)(i) of the Exchange Act, using
1,748,649,762 common shares outstanding as of December 6, 2000. In
calculating this amount for each holder, we treated as outstanding the
number of common shares issuable upon conversion of all of that holder's
LYONs, but we did not assume conversion of any other holder's LYONs. Does
not include common shares that may be issued by us upon purchase of LYONs
by us at the option of the holder.
(3) Merrill Lynch, Pierce, Fenner & Smith Incorporated and Tyco International
Ltd. and its affiliates have, within the past three years, engaged in, and
may in the future engage in, investment banking and other commercial
dealings, and Merrill Lynch acted as the initial purchaser in the private
placement in which the LYONs were originally issued. Merrill Lynch has
received customary fees and commissions for these transactions.
(4) Information about other selling securityholders will be set forth in
prospectus supplements, if required.
(5) Assumes that any other holders of LYONs, or any future pledgees, donees,
assignees, transferees or successors of or from any such other holders of
LYONs, do not beneficially own any common shares other than the common
shares issuable upon conversion of the LYONs at the initial conversion
rate.
Investing in the LYONs involves risks that are described in the "Risk
Factors Relating to the LYONs" section beginning on page 12 of the prospectus.
Neither the Securities and Exchange Commission, any state securities
commission nor any other regulatory body has approved or disapproved of these
securities or determined if this prospectus is truthful or complete. Any
representation to the contrary is a criminal offense.
The date of this prospectus supplement is January 12, 2001.
