Explanation of Responses:

1. This Form 4 Amendment is being filed to amend the Form 4 filed on December 28, 2006, to amend the above line item. The number of shares of common stock acquired is 924,554, rather than 924,545, as previously reported. The revised footnotes for the transactions shall also read as follows:

2. The Reporting Person is the Managing Member of Krovim LLC, which owns the 1,164,554 shares of common stock reported herein.

3. These 960,000 Warrants were previously reported in a footnote in a Form 3 filed by Krovim LLC on January 12, 2005. The Warrants were held in escrow and were not exercsiable until the earlier of (i) three years from the Termination Date or (ii) the date on which the closing price of the shares of Common Stock has equaled or exceeded $1.00 per share on the NASDAQ Bulletin Board, NASDAQ National Market System or on the American or New York Stock Exchange for at least ten (10) consecutive trading days. On December 19, 2006, a condition releasing the Warrants from escrow was met. The 960,000 Warrants were exercised on a cashless basis, converting into 924,554 shares of common stock of the Issuer, and which is being reported as an acquisition on this Form 4.
