Explanation of Responses: (1) The option was granted on August 26, 1998 and was to expire on or about August 26, 2000. The option was exercised by the payment of $8,611.10 in cash and the $7,741,378.90 balance of the purchase price was paid in the form of a one year limited recourse promissory note (the "Note") made by Energy Systems Investors LLC ("ESI"), of which the Reporting Person is a manager, in favor of the Issuer. The obligations evidenced by the Note are secured by a pledge of the 861,110 shares of Series A Convertible Preferred Stock (the "Series A Stock"). At the end of July 2000, the Reporting Person owned an aggregate of 1,083,332 shares of Series A Stock of which 222,222 shares were owned by Lawrence I. Schneider directly and 861,110 shares were owned by ESI. The 222,222 shares of Series A Stock had previously been transferred by ESI to Lawrence I. Schneider (individually) in accordance with Rule 16a-13. Each share of Series A Stock is currently convertible into four shares of the Issuer's Common Stock. /s/ Lawrence I.
