STOCKHOLDERS’ EQUITY

Common Stock.

At our Annual Meeting of Stockholders, held on May 23, 2012, our stockholders approved an amendment to our certificate of incorporation to increase the authorized number of shares of our common stock from 100,000,000 to 150,000,000.

On February 7, 2012 we entered into definitive agreements with institutional and other accredited investors and raised approximately $22.0 million in a private placement financing ("Private Placement"), which includes an aggregate of $3.0 million in convertible notes issued in December 2011 to entities associated with Third Security, LLC, a related party, that automatically convert into shares of our common stock and warrants to purchase such common stock on the same terms as all investors in the Private Placement. Pursuant to the purchase agreement, we issued an aggregate of 19,000,000 shares of our common stock at a price per share of $1.00, as well as five-year warrants to purchase up to an aggregate of 9,880,000 shares of common stock with an exercise price of $1.25 per share. In connection with the conversion of the convertible notes issued by us to the entities associated with Third Security, LLC, the entities received an aggregate of 3,000,000 shares of common stock and 1,500,000 warrants on the same terms as all investors in the Private Placement. The costs incurred to complete the Private Placement were recorded as a reduction in equity in the amount of $1.5 million. Net proceeds from this offering have been used for general corporate and working capital purposes, primarily to accelerate development of several of our key initiatives.

In connection with the Private Placement the investors have a Registration Rights Agreement which required the Company to maintain an effective registration statement with the SEC. Pursuant to and as required by the Registration Rights Agreement, on March 21, 2012, the Company filed a registration statement on Form S-1 registering the securities for resale. The registration statement was declared effective by the SEC on April 4, 2012.

Common Stock Warrants.

Common stock warrants issued during the year ended December 31, 2012 were 11,380,000, and none of the issued warrants were exercised. No common stock warrants were issued during the year ended December 31, 2011. Laurus Master Fund, Ltd. exercised its warrants during 2011 in a cashless exercise for 60,150 shares of common stock. Warrants to purchase an aggregate of 16,552,408 shares of common stock were outstanding at December 31, 2012.

(1) This Warrant was issued in connection with the issuance of warrants to purchase shares of our Series A Preferred Stock to affiliates of Third Security, LLC in December 2010. The number of underlying shares shown reflects the number of shares of common stock issuable upon conversion of the shares of Series A Preferred Stock for which this Warrant is currently exercisable.

(2) These Warrants were issued in connection with the Private Placement completed in February 2012 and are classified as a liability in our financial statements. See Note 12 Fair Value. These warrants also contain certain anti-dilution provisions that provide for an adjustment to the exercise price and number of shares issuable upon exercise of the warrant in the event that we engage in certain issuances of shares of our common stock at a price lower than the exercise price of the warrant.

Preferred Stock.

The Company’s Board of Directors is authorized to issue up to 15,000,000 shares of preferred stock in one or more series, from time to time, with such designations, powers, preferences and rights and such qualifications, limitations and restrictions as may be provided in a resolution or resolutions adopted by the Board of Directors. The authority of the Board of Directors includes, but is not limited to, the determination or fixing of the following with respect to shares of such class or any series thereof: (i) the number of shares; (ii) the dividend rate, whether dividends shall be cumulative and, if so, from which date; (iii) whether shares are to be redeemable and, if so, the terms and amount of any sinking fund providing for the purchase or redemption of such shares; (iv) whether shares shall be convertible and, if so, the terms and provisions thereof; (v) what restrictions are to apply, if any, on the issue or reissue of any additional preferred stock; and (vi) whether shares have voting rights. The preferred stock may be issued with a preference over the common stock as to the payment of dividends. We have no current plans to issue any additional preferred stock. Classes of stock such as the preferred stock may be used, in certain circumstances, to create voting impediments on extraordinary corporate transactions or to frustrate persons seeking to effect a merger or otherwise to gain control of the Company. For the foregoing reasons, any additional preferred stock issued by the Company could have an adverse effect on the rights of the holders of the common stock.

On December 29, 2010, we entered into a transaction with the Third Security Investors, pursuant to the terms of Series A Convertible Preferred Stock Purchase Agreement (“Series A Purchase Agreement”), in which we: (i) sold an aggregate of 2,586,205 shares of Series A Preferred Stock at a price of $2.32 per share; and (ii) issued Series A Warrants to purchase up to an aggregate of 1,293,102 shares of Series A Preferred having an exercise price of $2.32 per share (the sale of Series A Preferred Stock and issuance of the Series A Warrants hereafter referred to as the “Financing”). The Series A Warrants may be exercised at any time from December 29, 2010 until December 28, 2015 and contain a “cashless exercise” feature. The gross proceeds from the Financing were $6.0 million. The $0.2 million of costs incurred to complete the Financing were recorded as a reduction in the value of the Series A Preferred Stock. We used the net proceeds from the financing to acquire the FAMILION family of genetic tests from PGxHealth, a subsidiary of Clinical Data, Inc. Until the November 2011 modifications, the Series A Preferred Stock met the definition of mandatorily redeemable stock as it is preferred capital stock that is redeemable at the option of the holder through December 2015 and was reported outside of equity. The Series A Preferred Stock was to be accreted to its redemption value of $6.0 million. Until the November 2011 modifications, the Series A Warrants did not qualify to be treated as equity and, accordingly, were recorded as a liability. A preferred stock anti-dilution feature is embedded within the Series A Preferred Stock that met the definition of a derivative.

In connection with the Financing, we filed a Certificate of Designation of Series A Convertible Preferred Stock (the “Certificate of Designation”) with the Secretary of State of the State of Delaware, designating 3,879,307 shares of our preferred stock as Series A Preferred Stock. The Series A Preferred Stock, including the Series A Preferred Stock issuable upon exercise of the Series A Warrants, is convertible into shares of our common stock at a rate of 4-for-1, which conversion rate is subject to further adjustment as set forth in the Certificate of Designation. Certain rights of the holders of the Series A Preferred Stock are senior to the rights of the holders of common stock. The Series A Preferred Stock has a liquidation preference equal to its original price per share, plus any accrued and unpaid dividends thereon. The holders of the Series A Preferred Stock are entitled to receive quarterly dividends, which accrue at the rate of 10% of the original price per share per annum, whether or not declared, shall compound annually and shall be cumulative. In any calendar quarter, we are required to pay from funds legally available a cash dividend in the amount of 50% of the distributable cash flow as defined in the Series A Purchase Agreement or the aggregate amount of dividends accrued on the Series A Preferred Stock. During the years ended December 31, 2012 and 2011, we recorded $0.7 million and $0.6 million in accrued dividends, respectively.

Generally, the holders of the Series A Preferred Stock are entitled to vote together with the holders of common stock, as a single group, on an as-converted basis. However, the Certificate of Designation provides that we shall not perform some activities, subject to certain exceptions, without the affirmative vote of a majority of the holders of the outstanding shares of Series A Preferred Stock. The holders of the Series A Preferred Stock also are entitled to elect or appoint, as a single group, two of the five directors of the Company.

In connection with the Financing, we also entered into a registration rights agreement with the Third Security Investors (the “Registration Rights Agreement”). Pursuant to the terms of the Registration Rights Agreement, the Company has granted the Third Security Investors certain demand, “piggyback” and S-3 registration rights covering the resale of the shares of common stock underlying the Series A Preferred Stock issued pursuant to the Series A Purchase Agreement and issuable upon exercise of the Series A Warrants and all shares of common stock issuable upon any dividend or other distribution with respect thereto.

In November 2011, we entered into a transaction with the Third Security Investors, pursuant to an Agreement Regarding Preferred Stock (the “Amendment Agreement”), in which the Third Security Investors agreed to (i) waive their rights to enforce the anti-dilution and redemption features of the Series A Preferred Stock and (ii) at the next annual shareholder meeting, vote to amend the Certificate of Designation to remove the anti-dilution and redemption features of the Series A Preferred Stock. In exchange, the Company issued shares of common stock to the Third Security Investors having an aggregate market value of $0.3 million

As a result of the Amendment Agreement, the values of the Series A Preferred Stock and Series A Warrants, including the Series A Preferred Stock conversion feature and Series A Warrant liability, were reclassified into shareholders equity as of the date of the Amendment Agreement.
