The Registrant has not filed its Annual Reports on Form 10-KSB for the years ended December 31, 2004 and 2005 primarily because the Registrant lacks the financial resources to engage an independent registered public accounting firm to conduct an audit of the related financial statements and because it lacks the staffing to prepare the Forms 10-KSB due in large part to the amount of time management has devoted and the amount of funds the Registrant has spent in responding to litigation. For the same reasons, the Registrant has been unable to file its Quarterly Reports on Form 10-QSB for 2005 and 2006, and is unable to predict when it will be able to make these filings. There can be no assurance that these filings will be made at all. PART IV - OTHER INFORMATION (1) Name and telephone number of person to contact in regard to this notification. George E.
