(1) Assumes conversion of all of the holder's LYONs at a conversion rate of
6.7054 shares of common stock per $1,000 principal amount at maturity of
the LYONs. This conversion rate is subject to adjustment, however, as
described
under "Description of LYONs--Conversion Rights--Conversion Adjustments and
Delivery of Common Stock" beginning on page 16 of the prospectus. As a
result, the number of shares of common stock issuable upon conversion of
the LYONs may increase or decrease in the future.
(2) Calculated based on Rule 13d-3(d)(1)(i) of the Exchange Act using
70,764,165 shares of common stock outstanding as of February 1, 2002. In
calculating this amount for each holder, we treated as outstanding the
number of shares of common stock issuable upon conversion of all of that
holder's LYONs, but we did not assume conversion of any other holder's
LYONs.
(3) Information about other selling securityholders will be set forth in
future prospectus supplements, as required.
(4) Assumes that any other holders of LYONs, or any future pledgees, donees,
assignees, transferees or successors of or from any other holders of
LYONs, do not beneficially own any shares of common stock other than the
shares of common stock issuable upon conversion of the LYONs at the
initial conversion rate.
(5) Total number of shares of common stock that may be sold and the related
percentage of common stock outstanding assumes the conversion in full of
all LYONs outstanding. However, as described under "Description of
LYONs--Conversion Rights" beginning on page 14 of the prospectus, a holder
of a LYON otherwise entitled to a fractional share of our common stock
will receive cash equal to the then current sale price of the fractional
share.
(6) Merrill Lynch, Pierce Fenner and Smith, Inc. was the initial purchaser in
connection with the private placement of the LYONs and, along with certain
of its affiliates, has engaged and may engage in investment banking
transactions with us and has from time to time acted as a financial
advisor to us.

Investing in the LYONs involves risks that are described in "Risk Factors
Relating to the LYONs" beginning on page 8 of the prospectus.
Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved these securities, or determined if this
