Explanation of Responses:

1. Pursuant to the convertible promissory note issued by the reporting person to Dennis Ryll (the "Class 3 Plan Note"), on February 22, 2011, Dr. Ryll elected to convert his quarterly Class 3 automatic conversion amount of $619,738 (which includes both principal and interest) into 869,686 shares of the Company's common stock owned by the reporting person, at a conversion price of $0.71 per share, which equals the average of the trading price of shares of the Company's common stock (as determined in accordance with the Class 3 Plan Note and the Plan) for the ten (10) consecutive trading days ending on the trading day that is immediately preceding the then applicable Class 3 Automatic Conversion Date.

2. Pursuant to the 8.5% Secured Convertible Debentures due November 17, 2012 (Class 5 under our Joint Plan of Reorganization)(the "Debentures"), the holders elected to exchange a portion (or all) of the outstanding balance of their Debentures into shares of the Company's common stock owned by the reporting person. The conversion price for the principal amount under the Debentures is $0.75 per share (the "Exchange Price"). The conversion price for the interest amount under the Debentures is $0.65 per share for certain holders to $0.66 per share for other holders which is 90% of the average of the Company's VWAPs for the 20 consecutive trading days ending on the trading day that is immediately prior to the applicable interest payment date.
