Convertible Preferred Stock, Terms of Conversion                           The Series B Convertible Preferred did not contain a redemption provision and an overall analysis of its features performed by the Company determined that it was more akin to equity and therefore, has been classified within stockholders' equity on the balance sheet. While the embedded conversion option ("ECO") was subject to an anti-dilution price adjustment, since the ECO was clearly and closely related to the equity host, it was not required to be bifurcated and accounted for as a derivative liability under ASC 815. The Company determined that the Series B Convertible Preferred did not contain a beneficial conversion feature, since the conversion price exceeded the estimated fair value of the Company's common stock as of the commitment date.The Series B Convertible Preferred Stock was convertible, at the option of the holder, at any time into shares of common stock on a one-for-one basis, subject to certain adjustments. In the event of any issuances by the Company for less than the in-force conversion price, the Series B Convertible Preferred Stock conversion price would be reduced on a weighted average basis. Each share of Series B Convertible Preferred Stock was automatically convertible into shares of common stock at the then effective conversion price: (i) immediately prior to the closing of a firm commitment underwritten initial public offering provided that (A) the aggregate offering price, net of underwriters' discounts and expenses, is at least $2.00 per share of common stock and (B) the aggregate proceeds of such offering are not less than $20,000,000; or (ii) the date specified by written consent or agreement of the holders of at least 75% of the then outstanding shares of preferred stock.

Convertible Preferred Stock, Terms of Conversion                           The Series A and Series A-2 Convertible Preferred Stock was convertible, at the option of the holder, at any time into shares of common stock on a one-for-one basis. In the event of any issuances by the Company for less than the in-force conversion price, the preferred stock conversion price would be reduced on a weighted average basis. Each share of preferred stock was automatically convertible into shares of common stock at the then effective conversion price: (i) immediately prior to the closing of a firm commitment underwritten initial public offering provided that (A) the aggregate offering price, net of underwriters' discounts and expenses, was at least $2.00 per share of common stock and (B) the aggregate proceeds of such offering were not less than $20,000,000; or (ii) the date specified by written consent or agreement of the holders of at least 75% of the then outstanding shares of preferred stock.
