The actual pro rata portion of such beneficial ownership that may be deemed to be attributable to the Reporting Person is not readily determinable because it is subject to several variables. Mr. McElwee disclaims beneficial ownership of these shares except to the extent of his proportionate interest in these shares.These shares of common stock were acquired upon the automatic exercise of warrants in a net exercise transaction in which shares issuable upon exercise were surrendered to pay the exercise price of the warrants. The net number of shares benefically owned following the reported transaction is set forth in the row immediately below./s/ James B. McElwee2003-07-16
