to our net loss. The Series D Convertible Preferred Stock, Series G Convertible Preferred Stock, Series H and H2 Convertible Preferred
Stock, Series J Convertible Preferred Stock and Series K Convertible Preferred Stock are presented below as if they were converted
into common shares according to the conversion terms.
