Conversion rights description                       A holder of Series D Preferred Stock is prohibited from converting Series D Preferred Stock into shares of Common Stock if, as a result of such conversion, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company’s Common Stock then issued and outstanding (with such ownership restriction referred to as the “Series D Beneficial Ownership Limitation”) immediately after giving effect to the issuance of the shares of Common Stock issuable upon conversion of the Series D Preferred Stock. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice to us. The conversion rate of the Series D Preferred Stock is subject to proportionate adjustments for stock splits, reverse stock splits and similar events, but is not subject to adjustment based on price anti-dilution provisions.                    
Description of trading activities                       If the Company fails to timely deliver shares of Common Stock upon conversion of the Series D Preferred Stock (the “Series D Conversion Shares”) within the time period specified in the Series D Certificate of Designation (within two trading days after delivery of the notice of conversion, or any shorter standard settlement period in effect with respect to trading market on the date notice is delivered), then the Company is obligated to pay to the holder, as liquidated damages, an amount equal to $25 per trading day (increasing to $50 per trading day on the third trading day and $100 per trading day on the sixth trading day) for each $5,000 of stated value of Series D Preferred Stock being converted which are not timely delivered. If the Company makes such liquidated damages payments, the Company is also not obligated to make Series D Buy-In (as defined below) payments with respect to the same Series D Conversion Shares
