<p style=' margin-bottom:12pt; margin-top:0pt; text-indent:0.58in;text-align:left;'><font size=2>As of November 7, 2007, 36 warrant holders exercised a total of 1,958,197 warrants to purchase a total of 1,958,197 shares of the Registrant&#146;s common stock pursuant to the Registrant&#146;s previous call of the warrants issued by the Registrant during October and November 2006. These shares of common stock are registered for resale under the Registrant&#146;s registration statement number 333-139354. The total cash that the Registrant received from these warrant exercises equals $4,347,197.34.  Following these warrant exercises, the Registrant has 19,109,090 shares of its common stock outstanding.</font></p>

<p style=' margin-bottom:12pt; margin-top:0pt; text-indent:0.5in;text-align:left;'><font size=2>All of the shares of common stock issued upon exercise of these warrants were issued in a private placement transaction exempt from registration pursuant to Section 4(2) of the Securities Act of 1933. This offering and sale qualified for exemption under Section 4(2) because the offer and sale did not involve a public offering due to the fact that the offer and sale was made to an insubstantial number of persons and due to the manner of the offering. The offering was done with no general solicitation or advertising by the Registrant. Based on an analysis of the above factors, the Registrant has met the requirements to qualify for exemption under Section 4(2) of the Securities Act of 1933 for this transaction. </font></p>
