During the two most recent fiscal years ended December 31, 2003 and 2002 and the subsequent interim period through September 30, 2004 (the "Reporting Period"), none of Eisner's reports on the Company's financial statements contained an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principle.
