Commission on November 13, 2007. As of December 31, 2007, the Reporting
Persons beneficially owned (i) $60,000,000 in principal amount
of 1.0%
Guaranteed Senior Unsecured Convertible Notes due 2012 (the “Prior Notes”)
collectively convertible into 3,333,333 shares (the “Prior Note Shares”)
of Issuer’s Common Stock and (ii) $50,000,000 in principal amount of 1.0%
Guaranteed Senior Unsecured Convertible Notes due 2012 (the “New Notes”,
and together with the Prior Notes, the “Notes”) collectively convertible
into 2,118,644 shares (the “New Note Shares”, and together with the Prior

cause the
aggregate number of shares of Common Stock of Issuer owned by the
Reporting Persons to exceed 9.99% of the outstanding shares of
