         WHEREAS, Purchasers have agreed to amend the (x) terms of the
Registration Rights Agreement, dated as of December 5, 2003, by and among the
Company and the Purchasers (the "Registration Agreement"), and (y) the terms of
the Warrants, by entering into that certain letter agreement, dated January 15,
2004, with the Company, pursuant to which the Purchasers (i) amended Section
6(b) of the Registration Agreement to permit the Company to include in the

an additional 3,000,000 shares of Common Stock on behalf of Persons other than
the Purchasers and their transferees and (ii) amended Section 11(b) of any
warrants whose underlying Warrant Shares are included in Registrable Securities
such that it shall not be deemed an event triggering anti-dilution protection
thereunder for the Company to issue other warrants to acquire shares of Common
Stock, at a $.75 per share exercise price (the "Additional Warrants"), if such
Additional Warrants are issued in consideration for a waiver granted to the
Company by the holders of the Additional Warrants of certain registration rights
held by the holders of such Additional Warrants (the "Amendment");

         WHEREAS, in consideration of the Amendment, the Company agreed to amend
the terms of the 20% Warrants by entering into an allonge to the 20% Warrants to
reduce the exercise price of such 20% Warrants from $1.00 per share of Common
Stock to $.75 per share of Common Stock (the "Reduction"); and

         WHEREAS, the Company and the Purchasers desire to effect the Reduction
and amend the 20% Warrants by entering into this Allonge.

         NOW, THEREFORE, in consideration of the mutual promises expressed
herein, and such other consideration as is hereby acknowledged by all parties
hereto as adequate consideration under the terms hereof, the parties hereto do
hereby agree as follows:

         1. Reduction of Exercise Price.

         The 20% Warrants are hereby amended by reducing the Exercise Price (as
defined therein) from $1.00 for one share of Common Stock to $.75 for one share
of Common Stock.

         2. Effect of Allonge.

         In all other respects, the 20% Warrants are confirmed, ratified, and
approved and, as amended by this Allonge, shall continue in full force and
effect.
