Assumes
conversion of all of the holder's notes at an initial conversion
rate of
16.7504 shares of common stock per $1,000 principal amount. This
initial
conversion rate is subject to adjustment in certain circumstances
and thus
the number of shares of common stock issuable upon conversion of
the notes
may increase or decrease in the future. The net share
settlement feature of the notes requires us, upon conversion, to
(i)
settle up to the full principal amount of the notes in cash and (ii)
issue
shares of common stock only to the extent that the value of the notes
is
in excess of the principal amount. As a result of this net share
settlement feature, we are unable to determine at this time if any
shares
of common stock will be issuable upon conversion. Because of this
uncertainty, we have assumed that the selling stockholders are offering
the maximum number of shares of common stock issuable upon conversion
without giving effect to the net share settlement
feature.

Calculated
based on Rule 13d-3(d)(1)(i) of the Securities Exchange Act of 1934,
as
amended, using 41,116,298 shares of common stock outstanding as of
August
6, 2007. In calculating this amount for each holder, we treated as
outstanding the number of shares of common stock issuable upon conversion
of all that holder's notes, but we did not assume conversion of any
other
holder's notes.
