                                EXPLANATORY NOTE

         This Amendment No. 2 to Schedule 13G (this "Amendment") amends and
restates in its entirety each of (i) the Schedule 13G originally filed on
December 7, 2006 (the "Original Schedule 13G") by and on behalf of Vision
Opportunity Master Fund, Ltd., a Cayman Islands company (the "Fund") and (ii)
Amendment No. 1 to the Original Schedule 13G ("Amendment No. 1") previously
filed on December 18, 2006. The Original Schedule 13G and Amendment No. 1 are
collectively referred to herein as the "Prior Statements." This Amendment is
being filed to reflect that as of the date hereof the Filers (as defined below)
do not beneficially own any shares of the Issuer's Common Stock. Further, the
Reporting Persons hereby note and correct the following errors contained in the
Prior Statements:

         o        In the Prior Statements, the Fund incorrectly reported the
transaction date of its second financing in the Issuer, China Fire & Security
Group, Inc., as December 5, 2006 instead of November 22, 2006.

         o        Additionally, in the Prior Statements, the Fund incorrectly
reported its beneficial ownership and percentage ownership in the Issuer by
using an outstanding shares count provided by the Issuer that included
securities that were to convert into shares of Common Stock automatically upon
the effectiveness of an amendment to the Issuer's articles of incorporation
(described in the next bullet point below). The Original Schedule 13G should
have reported that the Fund beneficially owned 1,384,616 shares of Common Stock,
representing 50.6% of the Issuer's outstanding Common Stock (based on 2,738,604
shares of Common Stock outstanding as of October 27, 2006, as reported on the
Issuer's Form 8-K filed on November 2, 2006). Amendment No. 1 should have
reported that the Fund beneficially owned 1,384,616 shares of Common Stock,
representing 37.8% of the Issuer's outstanding Common Stock (based on 3,661,677
shares of Common Stock outstanding as of December 11, 2006, as reported on the
Issuer's Preliminary Information Statement on Schedule 14C filed on December 20,
2006).

         o        As of January 31, 2007, the Fund's beneficial ownership in the
Issuer decreased due to the Issuer effecting an amendment to its articles of
incorporation which caused certain securities to automatically convert into
shares of Common Stock, thereby increasing the aggregate outstanding shares of
Common Stock. As of January 31, 2007, the Fund beneficially owned 1,384,616
common shares of Common Stock, representing 5.2% of the Issuer's outstanding
Common Stock (based on 26,461,678 shares of Common Stock outstanding as of
January 31, 2007, as reported on the Issuer's Definitive Information Statement
on Schedule 14C filed on January 9, 2007).

         o        Following January 31, 2007, the Fund disposed of all of its
shares of Common Stock of the Issuer (and all derivative securities thereof).
