Shares of the Series K Preferred Stock will be convertible at the option of the holder into common stock at a fixed conversion price equal to $0.004.  At no time, however, may the Series K Preferred Stock be converted if the number of shares of common stock to be received by the reporting person pursuant to such conversion, when aggregated with all other shares of common stock then beneficially (or deemed beneficially) owned by the reporting person, would result in reporting person beneficially owning more than 19.99% of all common stock then outstanding.
