Stock Purchase	NOTE 12. STOCK PURCHASE In 2012, we entered into a Securities Purchase Agreement with Abeja Ventures, LLC (“Abeja”), pursuant to which the Company agreed to sell and issue to Abeja at a purchase price of $1.03 per share for an aggregate purchase price of $14.4 million; (i) 14.0 million shares of the Company’s common stock (“Common Stock”); (ii) a warrant to purchase 7.0 million shares of Common Stock at an exercise price of $1.03 per share (the “$1.03 Warrant”); and (iii) another warrant to purchase 7.0 million shares of Common Stock at an exercise price of $2.00 per share (the “$2.00 Warrant”), with each warrant exercisable prior to the fifth anniversary of the closing of the transactions contemplated by the Securities Purchase Agreement (collectively, the “Investment”). The purchase of Common Stock and warrants pursuant to the Investment, which was consummated in June 2012, qualified for equity treatment. The respective values of the warrants and Common Stock were calculated using their relative fair values and both are classified under Contributed Capital. The value therefore recorded for the warrants was $5.9 million and for the Common Stock was $8.5 million. Both warrants were exercisable until June 26, 2017, which was the fifth anniversary of the date on which the warrants were issued. In 2013, Abeja exercised in full the $1.03 Warrant. On the same date, Abeja also exercised 92% of the $2.00 Warrant (Abeja exercised such warrant for 6.4 million shares, leaving 571,160 shares unexercised on that date). The Company received aggregate funds of $20.1 million in connection with such exercises. Shares issued by the Company in connection with the warrant exercises were issued directly to the members of Abeja on a pro rata basis in accordance with their membership interests and written exercise instructions provided to the Company by Abeja. Immediately after giving effect to the warrant exercises, Abeja also distributed in kind to its members (on a pro rata basis in accordance with their membership interests) the remaining shares of Common Stock held by that entity. In 2016, warrants to purchase 155,289 shares were exercised at an exercise price of $2.00 leaving 415,871 warrants for shares unexercised at December 31, 2017. The Company received funds totaling $311,000 in connection with these exercises which are recorded as common stock and contributed capital in the consolidated balance sheet. In 2017, warrants to purchase 370,307 shares were exercised at an exercise price of $2.00 leaving 45,564 warrants for shares unexercised. The Company received funds totaling $0.7 million in connection with these exercises which are recorded as common stock and contributed capital in the Consolidated Balance Sheet. The remaining 45,564 warrants for shares expired on June 26, 2017 and went unexercised.

NOTE 12. STOCK PURCHASE

In 2012, we entered into a Securities Purchase Agreement with Abeja Ventures, LLC (“Abeja”), pursuant to which the Company agreed to sell and issue to Abeja at a purchase price of $1.03 per share for an aggregate purchase price of $14.4 million; (i) 14.0 million shares of the Company’s common stock (“Common Stock”); (ii) a warrant to purchase 7.0 million shares of Common Stock at an exercise price of $1.03 per share (the “$1.03 Warrant”); and (iii) another warrant to purchase 7.0 million shares of Common Stock at an exercise price of $2.00 per share (the “$2.00 Warrant”), with each warrant exercisable prior to the fifth anniversary of the closing of the transactions contemplated by the Securities Purchase Agreement (collectively, the “Investment”). The purchase of Common Stock and warrants pursuant to the Investment, which was consummated in June 2012, qualified for equity treatment. The respective values of the warrants and Common Stock were calculated using their relative fair values and both are classified under Contributed Capital. The value therefore recorded for the warrants was $5.9 million and for the Common Stock was $8.5 million.

Both warrants were exercisable until June 26, 2017, which was the fifth anniversary of the date on which the warrants were issued.

In 2013, Abeja exercised in full the $1.03 Warrant. On the same date, Abeja also exercised 92% of the $2.00 Warrant (Abeja exercised such warrant for 6.4 million shares, leaving 571,160 shares unexercised on that date).
