| Preferred stock, conversion description | Each unit consisted of one (1) share of 0% Series F Preferred Stock and 878 Class X Warrants on a registered basis and 1,755 Class A Warrants on an unregistered basis. The Company sold a total of 1,250 Series F Preferred Stock, 2,193,750 Class A Warrants and 1,097,500 Class X Warrants under the agreement. Each share of Series F Preferred Stock, at the option of the holder at any time, may be converted into the number of shares of common stock of the Company determined by dividing the $2,000 (stated value per share of the Series F Preferred Stock) by a conversion price of $1.14 per share (approximately 2,193,750 shares of common stock), subject to adjustment. Each Class X Warrant is exercisable to acquire one share of our common stock and one Class Y Warrant at an exercise price of $1.14, for a period of six (6) months from the date of issuance. Each Class Y Warrant is exercisable to acquire one share of common stock at an exercise price of $1.14 per share, commencing six (6) months from the date of issuance (the "Initial Exercise Date") and will expire on a date that is the five (5) year anniversary of the Initial Exercise Date. Each Class A Warrant is exercisable to acquire one share of Common Stock at an exercise price of $1.14 per share, commencing six (6) months from the date of issuance and will expire on a date that is the five (5) year anniversary of the date of issuance. In aggregate, if all of the shares of common stock are issued on conversion of the Series F Preferred Stock and exercise of the Class A, Class X and Class Y warrants, the Company would issue a total of 6,582,500 shares of common stock (see Note 13). | ||||||||
