Explanation of Responses:

          (FN1) On July 20, 2001, the Issuer exercised its right under the
Series C Preferred Stock Purchase Agreement dated as of March 30, 2001, to sell
16,250 shares of Series C-1 Preferred Stock, par value $0.01 per share ("Series
C-1 Preferred Stock") to SCP Private Equity Partners II, L.P. ("SCP") at a
purchase price of $40.00 per share. SCP paid the Issuer $635,596, net of
transaction costs, for the shares. As of the end of July 2001, each share of
Series C-1 Preferred Stock was convertible into 100 shares of common stock of
the Issuer, subject to increase for dividends and dilutive issuances. As a
result of a one-for-five reverse stock split on the Issuer's common stock
effective as of August 21, 2001, as of the end of April 2002, SCP had the right
to convert each share of Series C-1 Preferred Stock into 20 shares of the
Issuer's common stock, subject to increase for dividends and dilutive issuances.
For purposes of Section 16 reporting, SCP is deemed to be a direct beneficial
owner of the derivative securities of the Issuer disclosed herein. SCP Private
Equity II, LLC (the "Manager") is deemed to be an indirect beneficial owner of
the derivative securities of the Issuer disclosed herein because of a
contractual agreement with SCP which grants the Manager the power to make voting
and investment decisions regarding the securities held by SCP.
