On :December 31, 2000, Mr. DeVore was awarded a warrant (as provided in the agreement) giving him the right to purchase 80,000 shares of our common stock at $0.20 per share :until December 31, 2004. In February 2001, the agreement was modified and extended through June 30, 2001. Mr. DeVore was elected a director in June 2001. In August 2001 :the agreement was extended through September 30, 2001 and Mr. DeVore was awarded another warrant, this one (as provided in the agreement) giving him the right to :purchase 40,000 shares of our common stock at $0.20 per share until December 31, 2004. As the 120,000 shares, upon purchase, would be restricted shares and there was no :public market, the awards were valued at $0. Following the expiration of the agreement, Mr. DeVore continued to provide financial advisory services on an as needed :basis. In 2002, for financial services rendered, he was paid $2,500 in the form of 2,500 shares of common stock and a B Warrant to purchase 1,250 shares.
