Item 4(a);	Amount Beneficially Owned; Percent of Class: On September 14, 2005, the
Item 4(b)	reporting person acquired a Warrant to Purchase Securities from the issuer which was exercisable for 375,756 shares of common stock. The Warrant contains anti-dilution provisions which reduce the exercise price of the Warrant and increase the number of shares issuable pursuant to the Warrant if certain securities are issued by the issuer at prices below the Warrant exercise price. The Warrant requires the issuer to give notice to the reporting person immediately upon any adjustment in the number or class of shares subject to the Warrant or in the Warrant exercise price as a result of the anti-dilution adjustments. To date, the reporting person has received no such notices from the issuer.

	In August 2005, the reporting person became aware of various securities issuances that the reporting person believed would result in an anti-dilution adjustment to increase the number of shares issuable pursuant to the Warrant. Based solely on information developed by the reporting person from public records, the reporting person believes that a securities issuance by the issuer on August 1, 2006, caused the Warrant to become exercisable for 1,980,506 shares of common stock. Based on 27,690,915 shares of common stock outstanding on July 25, 2006, as reported in the issuer’s Form 10-QSB filed with the SEC on August 11, 2006, plus the 1,980,506 shares issuable pursuant to the Warrant, the reporting person’s beneficial holdings (consisting of 1,980,506 shares issuable pursuant to the Warrant plus 100 shares owned) as of August 1, 2006, represented 6.7% of the issuer’s outstanding common stock.

	On August 25, 2006, the reporting person exercised the Warrant pursuant to the “net issuance” provisions of the Warrant for 1,541,472 shares instead of 1,980,506 shares. As a result of such exercise, based on 28,433,391 shares of common stock outstanding as of August 15, 2006, as reported in the issuer’s definitive Proxy Statement filed with the SEC on September 11, 2006, plus the 1,541,472 shares issuable upon exercise of the Warrant, the reporting person beneficially owned, as of August 25, 2006, a total of 1,541,572 shares, representing 5.1% of the issuer’s outstanding common stock.

	The Warrant also provides for the issuance of additional shares of common stock if at any time between exercise of the Warrant and January 15, 2009, the issuer issues certain securities at a price per share which is lower than the Warrant exercise price at the time the Warrant was exercised. On October 2, 2006, the issuer advised the reporting person of its intent to issue 1,328,890 shares of common stock to the reporting person in addition to the 1,541,472 shares upon exercise of the Warrant that it had not yet issued. As a result, as of the date hereof, the reporting person beneficially owns 2,870,462 shares of common stock, representing 8.2% of the issuer’s outstanding common stock (based on 32,320,213 shares outstanding on September 6, 2006 as reported in the issuer’s Form 8-K/A filed with the SEC on September 11, 2006, plus the 2,870,362 shares the issuer advised it would issue on October 2, 2006 to the reporting person).

Item 4(c)	For information regarding the number of shares as to which the reporting person has voting and dispositive power as of the date hereof, see Items 5 through 8 of page 2, which are incorporated herein by this reference.

Item 5	Ownership of Five Percent or Less of a Class: Not applicable

Item 6	Ownership of More than Five Percent on Behalf of Another Person: Not Applicable
