Explanation of Responses:

      (FN1) On March 30, 2001 the Issuer issued to SCP Private Equity
Partners II, L.P. ("SCP") (i) 37,500 shares of the Company's Series C-1
Preferred Stock, par value $0.01 per share (the "Series C-1 Preferred Stock"),
and (ii) a warrant (the "Warrant") to purchase up to 75,000 shares of the
Company's Series C-2 Preferred Stock, par value $0.01 per share (the "Series C-2
Preferred Stock") (at an initial exercise price of $40.00 per share, subject to
adjustment upon certain events), for an aggregate purchase price of $1,500,000.
Each share of Series C-1 Preferred Stock and Series C-2 Preferred Stock is
convertible into 100 shares of common stock of the Issuer, subject to increase
for dividends and dilutive issuances. Presently, SCP has the right to (1)
convert the Series C-1 Preferred Stock into 3,750,000 shares of the Issuer's
common stock; and (2) the right to exchange its Warrant into 25,000 shares of
Series C-2 Preferred Stock which is convertible into 2,500,000 shares of the
Issuer's common stock. Upon the earlier of approval of the stockholders of the
transactions contemplated by the Warrant or May 31, 2001, SCP will have the
right to exercise the remaining 50,500 shares of Series C-2 Preferred Stock
purchasable under the Warrant, which is convertible into 5,050,000 shares of the
Issuer's common stock. 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.
