/3/The securities reported herein include securities that the Reporting Persons
may acquire in the future through the conversion of (i) 650 shares of the Series
A Convertible Preferred Stock (the "Series A Preferred Shares"), which may be
converted by the Reporting Persons at any time prior to and including June 19,
2002, subject to extension under certain circumstances as described below (the
"Series A Maturity Date"), into shares of the Company's Class A Common Stock
(the "Common Stock") at the conversion price described below and (ii) 530 shares
of the Series B Convertible Preferred Stock (the "Series B Preferred Shares"),
which may be converted by the Reporting Persons at any time prior to June 14,
2004 (the "Series B Maturity Date"), into shares of Common Stock at the
conversion price of $12.50 (subject to adjustment to prevent dilution). The
number of shares of Common Stock into which the Series A Preferred Shares are
convertible as December 31, 2001 is based on a conversion price of $3.083. The
Series A Preferred Shares were issued on June 19, 2000, and the Series B
Preferred Shares were issued on June 14, 2001. At the election of the Company,
subject to certain limitations, the Series A Maturity Date may be extended until
June 19, 2004 (subject to further extension under certain circumstances). As of
December 31, 2001, the conversion price of the Series A Preferred Shares was
$3.083.

The Conversion Price for the Series A Preferred Shares (the "Series A Conversion
Price") initially was $33.3854 (subject to adjustment to prevent dilution). The
Series A Conversion Price is subject to an annual adjustment. If the average of
the weighted average price (as reported by Bloomberg) of the Common Stock on the
10 trading days following June 19, 2001, June 19, 2002, June 19, 2003 or June
19, 2004 (each, with respect to each such date, the "Market Price") is less than
the Series A Conversion Price in effect immediately prior to such date, then on
and after the 11th trading day following each such date the Series A Conversion
Price will be equal to the Market Price with respect to such date, subject to
further adjustment. As a result, if the weighted average price of the Common
Stock fluctuates, the number of shares of Common Stock which

holders of the Series A Preferred Shares may be deemed to beneficially own may
fluctuate without any action taken by the holders of the Series A Preferred
Shares.

On the Series A Maturity Date, the Company shall either redeem the outstanding
Series A Preferred Shares or convert the Series A 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 A Maturity Date. 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 A Preferred Shares may be deemed to
beneficially own will change at the Series A Maturity Date without any action
taken by the holders of the Series A Preferred Shares.

The Series A Preferred Shares accrue dividends at the rate of 7% per annum from
June 19, 2000, payable in cash or Common Stock at the option of the Company
(with certain exceptions) quarterly, beginning on the earlier of December 18,
2000 and the date that is 10 days after a registration statement covering the
Common Stock issuable upon conversion of the Series A Preferred Shares is
declared effective by the Securities and Exchange Commission. 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 the date of this Schedule 13G, the Series A
Preferred Shares had accrued dividends of approximately $114,684.93.

On the Series B Maturity Date, the Company shall either redeem the outstanding
Series B Preferred Shares or convert the Series B 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. 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 may be deemed to
beneficially own will change at the Series B Maturity Date without any action
taken by the holders of the Series B Preferred Shares.

The Series B 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 had accrued dividends of approximately $166,986.30.

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.
