The Special Committee has not set a definitive timetable for completion of the review process, and the Company does not anticipate making any further public statements about the proposed transaction or the activities of the Special Committee unless and until either it enters into a definitive agreement for a transaction, or the Special Committee determines that no such transaction will be effected.
