      NOW, THEREFORE, in consideration of the premises and the mutual promises,
conditions and covenants contained herein and other good and valuable
consideration, receipt of which is hereby acknowledged, the parties hereto agree
as follows:

      1.    The foregoing recitals are hereby incorporated herein by reference
            and acknowledged as true and correct by the parties hereto.

      2.    Sections 2(a) and (b) of the Agreement are hereby amended and
            restated in their entirety to read as follows:

                  "(a) Subject to the terms and conditions of this Agreement,
            the Company shall prepare and file, no later than April 7, 2006 (the
            "Scheduled Filing Deadline"), with the SEC a registration statement
            on Form S-1 or SB-2 (or, if the Company is then eligible, on Form
            S-3) under the Securities Act (the "Initial Registration Statement")
            for the resale by the Investors of the Registrable Securities, which
            includes at least 514,403,329 shares of Common Stock to be issued
            upon conversion of the Convertible Debentures and 30,000,000 shares
            of Common Stock to be issued upon exercise of the Warrants of even
            date herewith. The Company shall cause the Registration Statement to


            remain effective until the earlier of (i) all of the Registrable
            Securities have been sold or (ii) the date the Registrable
            Securities become eligible for sale without restriction under
            Section 144 (k) promulgated under the Securities Act of 1933, as
            amended. Prior to the filing of the Registration Statement with the
            SEC, the Company shall furnish a copy of the Initial Registration
            Statement to the Investors for their review and comment. The
            Investors shall furnish comments on the Initial Registration
            Statement to the Company within twenty-four (24) hours of the
            receipt thereof from the Company."

                  "(b) Effectiveness of the Initial Registration Statement. The
            Company shall use its best efforts (i) to have the Initial
            Registration Statement declared effective by the SEC no later than
            June 2, 2006 (the "Scheduled Effective Deadline") and (ii) to insure
            that the Initial Registration Statement and any subsequent
            Registration Statement remains in effect until all of the
            Registrable Securities have been sold, subject to the terms and
            conditions of this Agreement. It shall be an event of default
            hereunder if the Initial Registration Statement is not filed by the
            Scheduled Filing Deadline or declared effective by the SEC by the
            Scheduled Effective Deadline."

      3.    Notwithstanding anything to the contrary in the Transaction
            Documents, the Company hereby covenants that it shall have received
            sufficient consents from its shareholders to increase its number of
            authorized shares of Common Stock to the number set forth in the
            Transaction Documents by no later than April 28, 2006.

      4.    Notwithstanding anything to the contrary herein or in the
            Transaction Documents, in the event the Company fails to file the
            Registration Statement by the Scheduled Filing Deadline (as defined
            herein), or fails to receive sufficient consents to increase its
            number of authorized shares of Common Stock as set forth herein, the
            Company shall pay to Investors two (2) months of liquidated damages
            in accordance with the calculation set forth in Section 2 (c) of the
            Agreement, in addition to any remedies contained in the Transaction
            Documents.

                     [SIGNATURE PAGES TO IMMEDIATELY FOLLOW]
