be converted by the Reporting Persons at any time prior to and including June
14, 2004, into shares of Common Stock at the conversion price of $5.00.

On the Series B Maturity Date and Series C Maturity Date, the Company shall
either redeem the outstanding Series B Preferred Shares and Series C Preferred
Shares, or convert the Series B Preferred Shares and Series C Preferred Shares
into shares of Common Stock at a conversion price equal to 95% of the Common
Stock's average "weighted average price" (as reported by Bloomberg) for the 30
trading days immediately preceding the Series B Maturity Date and Series C
Maturity Date, respectively. As a result, as the weighted average price of the
Common Stock fluctuates, the number of shares of Common Stock which holders of
the Series B Preferred Shares and Series C Preferred Shares may be deemed to
beneficially own at the Series B Maturity Date and Series C Maturity Date may
change without any action taken by the holders of the Preferred Shares.

The Series B Preferred Shares and Series C Preferred Shares accrue dividends at
the rate of 12.5% per annum from June 14, 2001, payable in cash or Common Stock
at the option of the Company (with certain exceptions) on the first day of each
calendar quarter. If the Company meets the necessary requirements and elects to
pay dividends in shares of Common Stock, the conversion price for such dividends
would be equal to 95% of the arithmetic average of the weighted average prices
of the Common Stock on its principal market during the five (5) consecutive
trading days immediately preceding the dividend date. 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.

Item 5          Ownership of Five Percent or Less of a Class:
                                    Not Applicable.

Item 6          Ownership of More than Five Percent on Behalf of Another Person:
                                    Not Applicable.

Item 7          Identification  and  Classification  of the  Subsidiary  which
                Acquired the Security Being Reported on by the Parent Holding
                Company:
                                    See Item 2 above.

Item 8          Identification and Classification of Members of the Group:
                                    Not Applicable.

Item 9          Notice of Dissolution of Group:
                                    Not Applicable.
