Authorized Preferred and Common Stock

At December 31, 2012, the Company had authorized 6,000,000 shares of $0.001 par value preferred stock, of which 5,000,000 shares, designated as Series A-1 Convertible Preferred Stock, were issued and outstanding and 500,000 shares, designated as Series B Convertible Preferred Stock, were issued and outstanding (collectively, the “Preferred Stock”). At December 31, 2012, the Company had authorized 150,000,000 shares of $0.001 par value common stock of which 85,644,185 shares were outstanding or reserved for issuance. Of those, 36,761,864 shares were outstanding; 39,089,161 shares were reserved for the conversion of the outstanding Preferred Stock to common stock; 2,521,222 shares were reserved for the conversion of the $14,316,255 of debt outstanding under the credit facility with Pyxis; 4,334,780 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; 750,000 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 the expiration date of March 5, 2015; and 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 the expiration date of June 29, 2017.

On August 7, 2012, at the Company’s 2012 annual meeting, the Company’s shareholders approved an amendment to the Company’s Charter affecting an increase in authorized shares of common stock from 100,000,000 to 150,000,000 shares. The Company believes that the availability of additional shares for issuance from time to time in the Board of Directors’ discretion in connection with future financings, investment opportunities, stock splits or dividends, possible acquisitions or for other corporate purposes is desirable in order to avoid repeated separate amendments to the Company’s Charter and the delay and expense incurred in holding special meetings of the stockholders to approve such amendments. The Company currently has no specific understandings, arrangements, or agreements with respect to any financings, investment opportunities, stock splits or dividends, or acquisitions or for any other corporate purposes that would require the Company to issue a material amount of new shares of common stock.

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 pursuant to which Delta Dental purchased 500,000 shares of Series B Preferred Stock for gross proceeds of $3,000,000. Each share of Series B Preferred Stock is convertible into approximately 21.86 shares of common stock reflecting a conversion price of $0.2745 per share. 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 the warrants issued in the Preferred Stock transaction, 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.

The Preferred Stock accrues dividends at the rate of 8% of the original purchase price per year, payable only when, as and if declared by the Board of Directors and are non-cumulative. To date, no dividends have been declared on these shares. If the Company declares a distribution, with certain exceptions, payable in securities of other persons, evidences of indebtedness issued by the Company or other persons, assets (excluding cash dividends) or options or rights to purchase any such securities or evidences of indebtedness, then, in each such case the holders of the Preferred Stock shall be entitled to a proportionate share of any such distribution as though the holders of the Preferred Stock were the holders of the number of shares of common stock into which their respective shares of Preferred Stock are convertible as of the record date fixed for the determination of the holders of common stock entitled to receive such distribution.

In the event of any liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, the holders of the Preferred Stock shall be 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 December 31, 2012 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 are 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 is 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 further adjustment) by the conversion price in effect on the date the certificate is surrendered for conversion. As of December 31, 2012, the Series A-1 Preferred Stock was convertible into 28,160,200 shares of common stock reflecting a current conversion price of $0.3196 per share. Each share of Series B Preferred Stock is 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 further adjustment) by the conversion price in effect on the date the certificate is surrendered for conversion. As of December 31, 2012, the Series B Preferred Stock was convertible into 10,928,961 shares of common stock reflecting a current conversion price of $0.2745 per share.

Each holder of Preferred Stock is 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 will be entitled to a number of votes equal to the number of shares of common stock into which it is convertible on the applicable record date.
