                  (2) The definition of the term "Registration Statement" is
hereby amended to include the Non-Escrow Registration Statement and the Escrow

                  (3) The provisions of Section 2(c) of the Registration Rights
Agreement are hereby amended to add the following:

                  (A) For purposes of determining the amount of any payment
         pursuant to Section 2(c) of the Registration Rights Agreement that is
         payable by the Company to a particular Investor by reason of a
         Registration Default specified in clause (iii) or clause (iv) of the

         to the Escrow Agreement at the time the Non-Escrow Registration
         Statement is filed with the SEC and which are released from such escrow

                  (4) Notwithstanding Section 2(c) of the Registration Rights
Agreement, any obligation of the Company to pay any amount pursuant to such
Section 2(c) may be satisfied by the Company by delivery to the Holder entitled
to such payment, on or before the due date for such payment, of a number of
shares of Common Stock equal to the quotient obtained by dividing (x) the amount
of such payment, expressed in dollars, by (y) the lesser of (i) the conversion
price in effect under Section 2 of this Agreement at the time such payment is
due and (ii) the average closing bid price of the Common Stock for the five
Trading Days ending on and including the Trading Day immediately preceding the
due date for such payment. The Company may exercise its right to satisfy such
payment obligations with shares of Common Stock only by giving written notice of
such election to the Holder entitled to such payment not less than seven Trading
Days prior to the due date for such payment. The shares deliverable by the
Company in satisfaction of its obligations to make such payments shall be
Registrable Securities for purposes of the Registration Rights Agreement. The
Company may satisfy such payment obligations with shares of Common Stock only to
the extent the resale of such shares by the Holders (1) is covered by the
Registration Statement and the Registration Statement is effective and available
for use by the recipient of such shares at the time the Company delivers such
shares or (2) the Registration Statement covering such shares has been filed
with the SEC and is the Registration Statement of which the failure to file or
become effective is the basis on which the Company has become obligated to make
the payment that is being satisfied by the Company's delivery of such shares.

                  2. RIGHT TO CONVERT SERIES C PREFERRED STOCK.

                  (a) In addition to the right to convert shares of Series C
Preferred Stock into Common Stock pursuant to the Certificate of Designation,
the Holders and each person who from time to time is a holder of record of
outstanding shares of Series C Preferred Stock shall have the right to convert
such shares with the Company in whole at any time or in part from time to time
into fully paid and nonassessable shares of Common Stock on the basis provided
in this Agreement. Any such conversion of shares shall be made on the same basis
and pursuant to the same rights and procedures as provided in the Certificate of
Designation as if such conversion were a conversion of such share(s) of Series C
Preferred Stock pursuant to the Certificate of Designation; provided, however,
that for purposes of determining the number of shares of Common Stock for which
any share of Series C Preferred Stock may be so converted, the holder shall be
entitled to make such conversion as if the Conversion Price (as defined in the
Certificate of Designation) initially were $3.00, subject to adjustment as
provided in the Certificate of Designation on the same terms therein provided as
if the Conversion Price initially were $3.00.

                  (b) The provisions of the Certificate of Designation are by
this reference incorporated herein as if set forth in full at this place for
purposes of setting forth the rights of holders of Series C Preferred Stock to
convert shares of Series C Preferred Stock in accordance with the rights
provided in this Agreement. Each reference in the Securities Purchase Agreement,
the Registration Rights Agreement or the Certificate of Designation to the
"Conversion Price" shall be deemed a reference to the price at which shares of
Series C Preferred Stock may be converted for Common Stock from time to time
pursuant to this Agreement.

                  (c) The shares of Common Stock issuable or issued upon
conversion of shares of Series C Preferred Stock pursuant to this Agreement
shall be "Registrable Securities" for purposes of the Registration Rights
Agreement.

                  3. COMPANY REPRESENTATIONS AND WARRANTIES.

         The Company represents and warrants to, and covenants and agrees with,

or instrument to which the Company is a party or by which it or any of its
