Sale of Common stock	Note 10. Sale of Common stock On December 30, 2013, and as amended on March 27, 2014, the Company entered into an At–The–Market Offering Agreement (the “ATM Agreement”) with Ascendiant Capital Markets, LLC (the “Manager”). Pursuant to the ATM Agreement, the Company may offer and sell shares of its Common Stock (the “Shares”) having an aggregate offering price of up to $8.5 million from time to time through the Manager. The Company can use the net proceeds from any sales of Shares in the offering for working capital, capital expenditures, and general business purposes. For the year ended December 31, 2015, the Company sold approximately 3,155,000 Shares under the ATM Agreement for gross proceeds of approximately $1,695 before related expenses. The ATM Agreement expired by its terms in August 2015. On October 8, 2015, the Company entered into separate subscription agreements (the “Subscription Agreement”) with accredited investors (the “Investors”) relating to the issuance and sale of $700 of units (the “Units”) at a purchase price of $0.25 per Unit, with each Unit consisting of one share (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”) and a three year warrant (the “Warrants”) to purchase two shares of Common Stock at an initial exercise price of $0.25 per share (such sale and issuance, the “Private Placement”). The Warrants are exercisable at a price of $0.25 on the earlier of (i) one year from the date of issue or (ii) the occurrence of certain corporate events, including a private or public financing, subject to approval of the lead investor, in which the Company receives gross proceeds of at least $7,500; a spinoff; one or more acquisitions or sales by the Company of certain assets approved by the stockholders of the Company; or a merger, consolidation, recapitalization, or reorganization approved by the stockholders of the Company (each, a “Qualifying Transaction”). The Warrants may be exercised by means of a “cashless exercise” following the four–month anniversary of the date of issue, provided that the Company has consummated a Qualifying Transaction and there is no effective registration statement registering the resale of the shares of Common Stock underlying the Warrants (the “Warrant Shares”). The Company is prohibited from effecting an exercise of any Warrant to the extent that, as a result of any such exercise, the holder would beneficially own more than 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of such Warrant, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%. The Warrants are also subject to certain adjustments upon certain actions by the Company as outlined in the Warrants. Prior to receipt of shareholder approval, the warrants, when aggregated with the shares of common stock issued in the offering, shall not be exercisable into more than 19.99% of the number of shares of Common Stock outstanding as of the closing date. On December 22, 2015 the Company sold $172 of common stock at a price of $0.25 per share in a Registered Direct offering.

On December 30, 2013, and as amended on March 27, 2014, the Company entered into an At–The–Market Offering Agreement (the “ATM Agreement”) with Ascendiant Capital Markets, LLC (the “Manager”). Pursuant to the ATM Agreement, the Company may offer and sell shares of its Common Stock (the “Shares”) having an aggregate offering price of up to $8.5 million from time to time through the Manager. The Company can use the net proceeds from any sales of Shares in the offering for working capital, capital expenditures, and general business purposes. For the year ended December 31, 2015, the Company sold approximately 3,155,000 Shares under the ATM Agreement for gross proceeds of approximately $1,695 before related expenses. The ATM Agreement expired by its terms in August 2015.

On October 8, 2015, the Company entered into separate subscription agreements (the “Subscription Agreement”) with accredited investors (the “Investors”) relating to the issuance and sale of $700 of units (the “Units”) at a purchase price of $0.25 per Unit, with each Unit consisting of one share (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”) and a three year warrant (the “Warrants”) to purchase two shares of Common Stock at an initial exercise price of $0.25 per share (such sale and issuance, the “Private Placement”).

The Warrants are exercisable at a price of $0.25 on the earlier of (i) one year from the date of issue or (ii) the occurrence of certain corporate events, including a private or public financing, subject to approval of the lead investor, in which the Company receives gross proceeds of at least $7,500; a spinoff; one or more acquisitions or sales by the Company of certain assets approved by the stockholders of the Company; or a merger, consolidation, recapitalization, or reorganization approved by the stockholders of the Company (each, a “Qualifying Transaction”). The Warrants may be exercised by means of a “cashless exercise” following the four–month anniversary of the date of issue, provided that the Company has consummated a Qualifying Transaction and there is no effective registration statement registering the resale of the shares of Common Stock underlying the Warrants (the “Warrant Shares”). The Company is prohibited from effecting an exercise of any Warrant to the extent that, as a result of any such exercise, the holder would beneficially own more than 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of such Warrant, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%. The Warrants are also subject to certain adjustments upon certain actions by the Company as outlined in the Warrants. Prior to receipt of shareholder approval, the warrants, when aggregated with the shares of common stock issued in the offering, shall not be exercisable into more than 19.99% of the number of shares of Common Stock outstanding as of the closing date.

On December 22, 2015 the Company sold $172 of common stock at a price of $0.25 per share in a Registered Direct offering.
