Convertible Preferred Stock	5. Convertible Preferred Stock On April 23, 2013, the Company entered into a Series B Convertible Preferred Stock and Warrant Purchase Agreement (the “Purchase Agreement”), pursuant to which the Company could raise, at any time on or prior to May 10, 2013, up to approximately $60.0 million through the issuance of (1) up to 980,000 shares of its Series B preferred stock (the “Series B Shares”) and (2) warrants to acquire up to 2,450,000 shares of its common stock with an exercise price of $6.142 per share. On April 23, 2013, the Company consummated a first closing under the Purchase Agreement, whereby in exchange for aggregate proceeds of approximately $43.0 million, it issued 700,098 Series B Shares and warrants to purchase up to a total of 1,750,248 shares of its common stock. On May 10, 2013, the Company consummated a second closing under the Purchase Agreement, whereby in exchange for aggregate proceeds of approximately $0.1 million, it issued 1,137 Series B Shares and warrants to purchase up to a total of 2,843 shares of its common stock. The rights, preferences, and privileges of the Series B convertible preferred stock (“Series B”) and the Series A-1 convertible preferred stock (“Series A-1”), Series A-2 convertible preferred stock (“Series A-2”), Series A-3 convertible preferred stock (“Series A-3”), Series A-4 convertible preferred stock (“Series A-4”), Series A-5 convertible preferred stock (“Series A-5”) and Series A-6 convertible preferred stock (“Series A-6”) (the Series A-1, Series A-2, Series A-3, Series A-4, Series A-5 and Series A-6, collectively, the “Series A Preferred Stock”) as of June 30, 2013, are set forth below. Conversion— Each holder of Series B Shares has the right, at their option at any time, to convert any such shares of Series B into such number of fully paid shares of common stock as is determined by dividing the original purchase price of $61.42 by the conversion price (“Series B Optional Conversion”). The conversion price of the Series B as of June 30, 2013 was $6.142 per share (the “Series B Conversion Price”), which represents a conversion ratio of one share of Series B into ten shares of common stock. Each holder of Series A-1, Series A-2 and Series A-3 has the right, at their option at any time, to convert any such shares of preferred stock into such number of fully paid shares of common stock as is determined by dividing the original purchase price of $81.42 by the conversion price (“Optional Conversion”). The original conversion price of the Series A-1, Series A-2 and Series A-3 was $8.142 per share (the “Conversion Price”), which represented a conversion ratio of one share of Series A-1, Series A-2 or Series A-3 into ten shares of common stock. The issuance of the Series B Shares and accompanying warrants under the Purchase Agreement resulted in an adjustment to the Conversion Price of the Series A-1, Series A-2 and Series A-3 (the “Anti-Dilution Adjustment”). As a result of the Anti-Dilution Adjustment, the effective conversion price of each share of Series A-1, Series A-2 and Series A-3 was reduced to $7.627, which represents a conversion ratio of one share of Series A-1, Series A-2 or Series A-3 into 10.675 shares of common stock. Each holder of Series A-4, Series A-5 and Series A-6 has the right, at their option at any time, to convert any such shares of preferred stock into such number of fully paid shares of common stock as is determined by dividing the original purchase price of $81.42 by the conversion price. The conversion price of the Series A-4, Series A-5 and Series A-6 as of June 30, 2013 was $8.142 per share, which represents a conversion ratio of one share of Series A-4, Series A-5 or Series A-6 into ten shares of common stock. Upon an optional conversion, the holder of the converted Series B and Series A Preferred Stock is entitled to payment of all accrued, whether or not declared, but unpaid dividends in shares of the common stock of the Company at the then effective conversion price. Each share of the Series B and Series A Preferred Stock is automatically convertible into fully paid and non-assessable shares of common stock at the applicable conversion price (as described above) in effect upon (1) a vote of the holders of at least 70% of the outstanding shares of Series B, Series A-1, Series A-2 and Series A-3 to convert all shares of Series B and Series A Preferred Stock or (2) the common stock becoming listed for trading on a national stock exchange (“Special Mandatory Conversion”).
