As of December 31, 2001, the Series B Preferred Shares and Series C Preferred Shares had combined accrued dividends of approximately $1,001,918. Pursuant to the terms of the Preferred Shares, the Reporting Persons cannot be "beneficial owners" of more than 9.99% of the Common Stock within the meaning of Rule 13d-1 of the Securities Exchange Act of 1934.
