The reports of Coopers & Lybrand on the Company's financial statements for the years ended December 31, 1997 and 1996 did not contain an adverse opinion or a disclaimer of opinion, but the reports did contain explanatory paragraphs in each of the two years concerning the ability of the Company to continue as a going concern since the Company has not yet achieved profitability, has a working capital deficit and must obtain additional capital to fund its ongoing operations. There were no disagreements with Coopers & Lybrand on any matters of accounting principles or practices, financial statement disclosures, or auditing scope and procedures which, if not resolved to the satisfaction of Coopers & Lybrand, would have caused Coopers & Lybrand to make reference to the matter in their report. The Company has had discussions with, but has not yet identified a successor auditor. The Company has requested Coopers & Lybrand to furnish it a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements.
