Based
on information available to us as of October 30, 2007. The sum
of the number of shares beneficially owned by the selling stockholders
named in this table and in the table named in the prospectus supplements
dated August 23, 2007 and September 11, 2007, exceeds 6,499,134 shares
of
common stock (the total number of shares offered pursuant to the
prospectus supplement) because certain selling stockholders may have
transferred notes or otherwise reduced their position prior to selling
pursuant to this prospectus supplement, and as a result we received
beneficial ownership information from additional selling
stockholders. However, the maximum number of shares of common stock
that may be sold pursuant to the prospectus supplements will not
exceed
6,499,134 shares.

|
The
number of shares of common stock issuable upon the exchange or redemption
of the notes assumes exchange of the full amount of notes held by
each
selling stockholder at the initial exchange rate of 36.1063 shares
of our
common stock per $1,000 principal amount of notes and a cash payment
in
lieu of any fractional shares. The exchange rate is subject to adjustment
in certain events.
