At-the-market agreement terms, description We are also prohibited, until the date that the Preferred Purchasers no longer collectively hold at least 20% of the then-outstanding shares of Series A Preferred Stock issued pursuant to the SPA, from entering into an agreement to effect any issuance by us of Common Stock or Common Stock equivalents involving certain variable rate transactions. We also cannot enter into agreements related to "at-the-market" transactions for a period of 12 months. At the later of (i) the date that the August Warrants are fully exercised, and (ii) 12 months from the date of the SPA, we cannot draw down on any existing or future agreement with respect to "at-the-market" transactions if the sale of the shares in such transactions has a per share purchase price that is less than $3.76 (two times the exercise price of the Warrants).      
Preferred stock conversion, description Each share of Series A Preferred Stock is convertible, at any time and from time to time from and after the issuance date, at the holder's option in to that number of shares of Common Stock equal to the stated value per share (or $1,000) divided by the conversion price (initially, $1.55); thus, initially, each share of Series A Preferred Stock is convertible into approximately 645 shares of Common Stock. In certain circumstances, the Series A Preferred Stock is mandatorily convertible into shares of Common Stock after the Company obtains stockholder approval to issue a number of shares of Common Stock in excess of 19.99% and the closing price of the Common Stock is 100% greater than the then-base conversion price on each trading day for any 20 trading days during a consecutive 30-trading-day period.
