(1) Sellers Capital Master Fund, Ltd. is a privately offered collective investment vehicle. Sellers Capital LLC is the investment adviser to and has investment discretion over securities of the issuer held by Sellers Capital Master Fund, Ltd. and therefore may be considered an indirect beneficial owner of those securities. Mr. Sellers is the Managing Member of Sellers Capital LLC and therefore also may be considered an indirect beneficial owner of those securities. Sellers Capital LLC and Mr. Sellers each disclaim beneficial ownership of the securities except to the extent of their pecuniary interest therein.
(2) On March 6th, 2007, the number of shares beneficially owned, directly or indirectly, by the filing persons, pursuant to the definition of beneficial ownership set forth in Securities Exchange Act Rules 13d-3 and 16a-1(a)(1), exceeded 10 percent of the total shares outstanding of the class. However, due to an administrative oversight, a Form 3 was not filed with respect to the filing persons' interest in the shares.
