At December 31, 2013, the Company had authorized 6,000,000 shares of $0.001 par value preferred stock. The Company had authorized 300,000,000 shares of $0.001 par value common stock of which 198,521,806 shares were outstanding or reserved for issuance. Of those, 122,448,707 shares were outstanding; 6,288,950 shares were reserved for the potential exercise of outstanding stock options and for shares of common stock available for future grants under our stock plan; 638,887 shares were reserved for the potential exercise of rights held under the Employee Stock Purchase Plan; 1,750,000 shares were reserved for the exercise of outstanding warrants to purchase common stock at an exercise price of $1.30 per share which are exercisable currently until March 5, 2015; 437,158 shares were reserved for the exercise of outstanding warrants to purchase common stock at an exercise price of $0.2745 per share which are exercisable currently until June 29, 2017; 35,081,967 shares were reserved for the exercise of outstanding warrants to purchase common stock at an exercise price of $0.2745 per share, of which approximately 20,655,737 are currently exercisable until May 17, 2020 and the remaining are currently exercisable until August 9, 2020; and 31,876,137 shares are reserved for issuance of shares of common stock and warrants to purchase shares of common stock pursuant to the rights each investor in the May 2013 Private Placement to purchase any time prior to June 30, 2014 its pro rata share of up to an aggregate of $5,000,000 of additional shares of common stock and warrants on the same terms as those in the May 2013 Private Placement.

On June 29, 2012, the Company entered into an agreement with Pyxis to exchange the 5,000,000 shares of Series A Convertible Preferred Stock held by Pyxis for 5,000,000 shares of Series A-1 Convertible Preferred Stock (the “Series A-1 Preferred Stock”) and filed a new Certificate of Designation, Preferences and Rights of Preferred Stock with the State of Delaware for the Series A-1 Preferred Stock and Series B Convertible Preferred Stock (the “Series B Preferred Stock” and, with the Series A-1 Preferred Stock, the “Preferred Stock”). Concurrently therewith, the Company completed a financing with Delta Dental of Michigan, Inc. (“DDMI”) pursuant to which DDMI purchased 500,000 shares of Series B Preferred Stock for gross proceeds of $3,000,000. Net proceeds to the Company after fees and expenses were approximately $2.7 million. In addition, fully vested warrants to purchase 437,158 shares of common stock at an exercise price of $0.2745 per share were issued to the placement agent in the transaction. These warrants expire in five years. For purposes of determining the fair value of these warrants, the Black-Scholes pricing model was used with the following assumptions:

Risk-free interest rate	1	%
Expected life	5 years
Expected volatility	142.36	%
Dividend yield	0	%

Using these assumptions, the fair value of the warrants is $104,907.

In the event of any liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, the holders of the Preferred Stock were entitled to receive on a pari passu basis, prior and in preference to any distribution of any of the Company’s assets or surplus funds to the holders of its common stock by reason of their ownership thereof, the amount of two times the then-effective purchase price per share, as adjusted for any stock dividends, combinations or splits with respect to such shares, plus all declared but unpaid dividends on such shares for each share of Preferred Stock then held by them. The liquidation preference for the Preferred Stock at May 17, 2013, prior to the financing, was $24,000,000 in the aggregate, reflecting a liquidation preference of $18,000,000 for the Series A-1 Preferred Stock and $6,000,000 for the Series B Preferred Stock. After receiving this amount, the holders of the Preferred Stock were entitled to participate on an as-converted basis with the holders of common stock in any of the remaining assets.

Each share of Series A-1 Preferred Stock was convertible at any time at the option of the holder into a number of shares of the Company’s common stock determined by dividing the then-effective purchase price ($1.80, and subject to adjustment) by the conversion price in effect on the date the certificate was surrendered for conversion. The Series A-1 Preferred Stock was convertible into 28,160,200 shares of common stock reflecting a conversion price of $0.3196 per share. Each share of Series B Preferred Stock was convertible at any time at the option of the holder into a number of shares of the Company’s common stock determined by dividing the then-effective purchase price ($6.00, and subject to adjustment) by the conversion price in effect on the date the certificate was surrendered for conversion. The Series B Preferred Stock was convertible into 10,928,961 shares of common stock reflecting a conversion price of $0.2745 per share. All shares of Preferred Stock were converted to common stock on May 17, 2013 in connection with the private placement described below, resulting in the issuance of 39,089,161 shares of common stock. As of December 31, 2013 no shares of preferred stock are issued and outstanding.

Each holder of Preferred Stock was entitled to vote its shares of Preferred Stock on an as-converted basis with the holders of common stock as a single class on all matters submitted to a vote of the stockholders, except as otherwise required by applicable law. This means that each share of Preferred Stock was entitled to a number of votes equal to the number of shares of common stock into which was convertible on the applicable record date.

On May 17, 2013, the Company entered into a Common Stock Purchase Agreement with various accredited investors (the “Purchasers”), pursuant to which the Company sold securities to the Purchasers in a private placement transaction. The Company sold an aggregate of 43,715,847 shares of its common stock, at a price of $0.2745 per share for gross proceeds of $12,000,000. The Purchasers also received warrants to purchase up to an aggregate of 32,786,885 shares of Common Stock at an exercise price of $0.2745 per share (the “Warrants”). The Warrants were exercisable as to 63% of the shares immediately and as to 37% of the shares following receipt of shareholder approval of a share authorization increase and have a term of seven years from the date they become exercisable. For Warrants that were exercisable upon shareholder approval of an increase in the Company’s authorized shares of common stock, the Company recorded a non-current liability at June 30, 2013 based on the allocation of the relative fair values of the common stock and Warrants issued in the private placement. In addition, the Company recognized non-cash interest expense of $286,579 representing the increase in the fair value of the warrant liability from the date of issuance to June 30, 2013. On August 9, 2013, the Company’s shareholders’ approved an amendment to the Company’s Certificate of Incorporation to increase the number of authorized shares of common stock from 150,000,000 to 300,000,000 shares. Following the shareholder approval of the increase in authorized shares on August 9, 2013 the Company filed a certificate of amendment with the Delaware Secretary of State, which provided for adequate authorized shares for all potential common stock equivalents issued pursuant to the financing on May 17, 2013. As a result, the warrant liability reflected as a non-current liability, in the June 30, 2013 balance sheet was reclassified to shareholders’ equity at its fair value as of August 9, 2013. The fair value of the warrant liability increased by approximately $11,000 from June 30, 2013 to August 9, 2013, and was recorded as an increase to interest expense in the statement of operations for the three months ended September 30, 2013.

For its services in this transaction, the placement agent received cash compensation in the amount of approximately $780,000 and the placement agent and an affiliate received warrants to purchase an aggregate of 2,295,082 shares of common stock, at an exercise price of $0.2745 per share (the “Placement Agent Warrants”). The Placement Agent Warrants became exercisable on August 9, 2013, following shareholder approval of an increase in the Company’s authorized shares of common stock and expire August 9, 2020. The cash compensation and the fair value of the warrants were recorded as issuance costs resulting in a reduction to shareholders’ equity.

For purposes of determining the fair value of the warrants exercisable upon shareholder approval of an increase in the Company’s authorized shares, the Black-Scholes pricing model was used with the following assumptions:

	May 17, 2013		June 30, 2013		August 9, 2013
Risk-free interest rate	1.35	%	1.58	%	2.53	%
Expected life	4 years		4 years		4 years
Expected volatility	144.63	%	145.62	%	146.19	%
Dividend Yield	0	%	0	%	0	%

Using these assumptions, the fair value of the warrants is $5,072,129 on May 17, 2013, $5,358,708 on June 30, 2013 and $5,369,676 on August 9, 2013.

In connection with this private placement, all preferred stockholders converted their shares of Preferred Stock to common stock in accordance with the terms noted above resulting in the issuance of 39,089,161 shares of common stock.

In addition, pursuant to the Common Stock Purchase Agreement, each Purchaser has the right, at any time on or before June 30, 2014, to purchase at one or more subsequent closings its pro rata share of up to an aggregate of $5,000,000 of additional shares of common stock and warrants on the same terms and conditions as those set forth above. If, prior to June 30, 2014, investors have not purchased their entire pro rata share of such additional investment of $5,000,000, those who have purchased their entire pro rata share of the additional investment, will be entitled to purchase the unsold portion of the additional investment.
