| 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. The holders of Series A Preferred Stock cannot convert the Series A Preferred Stock if, after giving effect to the conversion, the number of shares of our Common Stock beneficially held by the holder (together with such holder's affiliates) would be in excess of 4.99% (or, upon election by a holder prior to the issuance of any shares, 9.99% of the number of shares of Common Stock issued and outstanding immediately after giving effect to the issuance of any shares of Common Stock issuance upon conversion of the Series A Preferred Stock held by the holder). The conversion price of the Series A Preferred Stock is subject to certain customary adjustments, including upon certain subsequent equity sales and rights offerings. | |||
