The
following table presents securities that could potentially dilute basic loss per share in the future. For all periods
presented, the potentially dilutive securities were not included in the computation of diluted loss per share because these securities
would have been anti-dilutive to our net loss. The Series D Convertible Preferred Stock, Series G Convertible Preferred
Stock, Series H 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 in Note 5.
