Type of Reporting Person (See Instructions) CO Page 4 of 11 Pages 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).
