During the course of Swenson's review of the Company's interim financial statements during its current fiscal year ended September 30, 2007 and in preparation for Swenson's audit of the Company's year-end financial statements and the Company's report regarding the effectiveness of its internal controls, disagreements have arisen regarding the appropriate review philosophy and communication between Swenson and the Company's management and the appropriate review and audit scope related to the Company's report regarding the effectiveness of its internal controls, which have included disagreements with Swenson regarding the fees charged or to be charged by Swenson for such services. While the Company does not believe that such disagreements, if not resolved to Swenson's satisfaction, would have caused Swenson to make reference in connection with its report on the Company's financial statements to the subject matter of the disagreement, Swenson has advised the Company that such disagreements would have resulted in an adverse reference in Swenson's audit report on the Management's Report on Internal Control Over Financial Reporting. The Audit Committee discussed the subject matter of the disagreements described above with Swenson, and the Company has authorized Swenson to respond fully to the inquiries of the successor audit firm concerning the subject matter of each disagreement described above.
