The Board of Directors also determined that the Management Report on Internal Control over Financial Reporting as of September 30, 2005 and the Report of KPMG, LLP, the Company's independent registered public accounting firm, relating to the effectiveness of the Company's internal controls over financial reporting and management's assessment thereof as of September 30, 2005, both of which reports are included in the Company's Annual Report on Form 10-K for the year ended September 30, 2005, should not be relied upon. The Board has appointed a Special Committee of independent directors to conduct an internal investigation relating to past stock option grants, the timing of such grants and other related accounting and documentation issues. In the course of its investigation, issues have arisen relating to the integrity of documents concerning the Company's stock option grants. Also during the internal investigation, issues have arisen concerning the Company's practices in connection with credits issued to or requested by customers (for returned products or otherwise) and the related accounting treatment, as well as the application of payments received to the proper accounts receivable. The Special Committee is reviewing these issues and, pending further investigation, believes that the Company's accounts receivable and revenues may have been misstated during certain periods. Whether the Company's accounts receivable and revenues were misstated and, if so, the extent of such misstatements are still under investigation. The Company's Audit Committee has discussed the matters disclosed in this filing with the Company's independent registered public accounting firm.
