The complaint alleges that during the Class Period the Company, and one or more members of its senior management, violated federal securities laws by issuing various materially false and misleading statements that had the effect of artificially inflating the market price of the Company's securities and causing Class members to overpay for the securities.

No class has yet been certified in the above action. If you are a member of the proposed Class, you may, no later than July 24, 2007, ask the Court to allow you to serve as lead plaintiff for the proposed Class. To serve as a lead plaintiff, you must satisfy certain legal requirements. In making your decision, you should take into account that those with large financial losses resulting from the alleged federal securities law violations are given preference in being appointed lead plaintiff.
