conversion of all of the holder’s notes at an initial conversion rate of
20.3770 of our common shares for each $1,000 principal amount of
notes.
However, this conversion rate is subject to adjustment as described
under
“Description of Notes — Conversion Rate Adjustments.” As a result, the
amount of common shares issuable upon conversion of the notes may
increase
or decrease in the future.

Calculated
based on Rule 13d-3(d)(i) of the Exchange Act using
83,784,455 common shares outstanding as of January 28, 2008. In
calculating this amount, we treated as outstanding the number of
common
shares issuable upon conversion of all of that particular holder’s notes.
However, we did not assume the conversion of any other holder’s notes.
