Private placement, description	On November 12, 2014 and February 2, 2015, the Company completed a private placement of an aggregate of 626,600 shares of its Series A Preferred Stock (“Series A Stock”) together with warrants to purchase shares of its common stock (“Preferred Warrant”) at a price of $5.00 per share, in accordance with the Series A Preferred Stock Purchase Agreement dated October 20, 2014 (the “Purchase Agreement”). From the date of respective closings and prior to October 20, 2019 (the “Put/Call Exercise Period”), the investors may exercise a right to purchase and require the Company to sell up to an additional 673,400 shares of Series A Stock. If the investors have not exercised this right during the Put/Call Exercise Period, the Company may exercise a right to cause and require the investors to purchase up to an additional 673,400 shares of Series A Stock, for an aggregate purchase price of $3,367,000. In September 2015, all the residual call options were removed from the Preferred Series A Stock Purchase Agreements.
Private placement, conversion terms	Holders of the Series A Stock shall initially have the right to convert such shares of Series A Stock into the number of authorized but previously unissued shares of the Company’s common stock obtained by dividing the stated value of each share of Series A ($5.00) by $2.00. For each share of Series A Stock, the investors will receive 2.5 Preferred Warrants to purchase the Company’s common stock at an exercise price of $2.50 per share. The Preferred Warrants are exercisable immediately for a period of five years from the date of closing. The exercise price of the Preferred Warrants is subject to adjustments in the case of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. The exercisability of the Preferred Warrants may be limited if upon exercise, the warrant holder or any of its affiliates would beneficially own more than 4.99% of the Company’s Common Stock.
