| STOCKHOLDERS' EQUITY | STOCKHOLDERS’ DEFICIT Common Stock. Pursuant to our Third Amended and Restated Certificate of Incorporation, as amended, we currently have 150,000,000 shares of common stock authorized for issuance. On January 6, 2016, we entered into a Securities Purchase Agreement (the “SPA”) with certain accredited investors (the “2016 Investors”), pursuant to which, on January 8, 2016, we sold to the 2016 Investors, and the 2016 Investors purchased from us (the “January 2016 Offering”), an aggregate of approximately $2.2 million of units (the “Units”) consisting of (a) an aggregate of 2,365,243 shares (the “A-1 Preferred Shares”) of our Series A-1 Convertible Preferred Stock (the “A-1 Preferred”), and (b) warrants (the “2016 Warrants”) to purchase up to an aggregate of 1,773,929 shares of our common stock, with an initial value of $1.8 million . The gross amount of $2.2 million included $2.0 million of cash proceeds and $0.2 million of debt settled with the issuance of preferred stock and warrants. Each Unit was sold to the 2016 Investors at a purchase price of $0.93 per Unit. The A-1 Preferred Shares are convertible into shares of our common stock at an initial rate of 1-for-1, which conversion rate is subject to further adjustment as set forth in our Certificate of Designation of Series A-1 Convertible Preferred Stock, which was filed with the Secretary of State of the State of Delaware on January 8, 2016 (the “Series A-1 Certificate of Designation”). We determined there was a beneficial conversion feature (“BCF”) in connection with this issuance and valued the BCF at $0.4 million . The holders of the A-1 Preferred were able to convert at any time following the issuance. Accordingly, we recorded a dividend totaling $0.4 million during 2016 related to this beneficial conversion, which was recorded against additional paid in capital. Pursuant to the terms of the Series A-1 Certificate of Designation, the holders of the A-1 Preferred Shares will generally be entitled to that number of votes as is equal to the product obtained by multiplying: (i) the number of whole shares of our common stock into which the A-1 Preferred may be converted as of the record date of such vote or consent, by (ii) 0.93 , rounded down to the nearest whole number. Therefore, every 1.075269 shares of A-1 Preferred will generally initially be entitled to one vote. In May 2016, 2,150,538 of the A-1 Preferred Shares were converted into 2,150,538 shares of our common stock. At March 31, 2017, there were 214,705 A-1 Preferred Shares outstanding. The 2016 Warrants were immediately exercisable upon issuance, have a term of five years and have an exercise price of $1.21 per share of our common stock. Each 2016 Warrant includes both cash and “cashless exercise” features and an exchange feature whereby the holder of the 2016 Warrant may exchange (the “Exchange Right”) all or any portion of the 2016 Warrant for a number of shares of our common stock equal to the quotient obtained by dividing the “Exchange Amount” by the closing bid price of our common stock on the second trading day prior to the date the 2016 Warrant is exchanged (the “Exchange Price”). Under the 2016 Warrants, the “Exchange Amount” is based upon a Black Scholes option pricing model, and the aggregate Exchange Amount under all of the 2016 Warrants will be $1.4 million, subject to adjustment to the extent that the risk-free U.S. Treasury rate fluctuates between the date of issuance of the 2016 Warrants and the date the 2016 Warrants are exchanged. Each 2016 Warrant provides that the number of shares that may be issued upon exercise of the Exchange Right is limited to the number of shares that may be purchased pursuant to the terms of the 2016 Warrant, unless we have previously obtained stockholder approval or approval from The Nasdaq Stock Market LLC to issue any additional shares of our common stock (the “Additional Shares”) pursuant to the Exchange Right (the “Required Approvals”). For any Exchange Right exercised more than 90 days following the issuance of the 2016 Warrants, if we have not obtained either of the Required Approvals, we will be required to pay the 2016 Warrant holder an amount in cash for any Additional Shares that we cannot issue without the Required Approvals based on the Exchange Amount. The 2016 Warrants further provide that, to the extent the closing bid price of our common stock on the second trading day prior to the date the 2016 Warrant is exchanged is less than $0.50 , the Exchange Price will be deemed to be equal to $0.50 , and, in addition to issuing shares of our common stock based on this Exchange Price, we will be required to pay to the 2016 Warrant holder an amount in cash equal to the product obtained by multiplying (a) $0.50 minus the closing bid price of our common stock on the second trading day prior to the date the 2016 Warrant is exchanged, by (b) the aggregate number of shares of our common stock issued to the 2016 Warrant holder by the Company in such exchange at an Exchange Price equal to $0.50 . Therefore, if the Required Approvals are obtained, based on the Exchange Amount of $1,436,882 (which, as noted above, is subject to adjustment to the extent that the risk-free U.S. Treasury rate fluctuates between the date of the issuance of the 2016 Warrants and the date the 2016 Warrants are exchanged), the maximum number of shares of our common stock issuable pursuant to the Exchange Right in the 2016 Warrants will be 2,873,765 . In addition, if, for example, assuming an Exchange Amount of $1,436,882 , the closing bid price of our common stock on the second trading day prior to the date the 2016 Warrants are exchanged is $0.25 , we would be required to pay to the 2016 Warrant holders cash in an aggregate amount of $718,441 in addition to issuing the 2016 Warrant holders 2,873,765 shares. During the year ended December 31, 2016, 1,006,419 of the 2016 Warrants were exchanged for 1,613,353 shares of our common stock and cash due of $0.5 million . As of March 31, 2017 and December 31, 2016, the $0.5 million due to a 2016 Investor is included in other current liabilities on our condensed consolidated balance sheet. In accordance with the terms of the SPA, we amended that certain Series A Warrant to purchase up to an aggregate of 1,161,972 shares of our common stock previously issued by us to an affiliate of one of the 2016 Investors on July 7, 2015 (the “Original Warrant”), as previously reported by us on our Amendment No. 1 to Current Report on Form 8-K/A, filed with the SEC on July 7, 2015 (as so amended, the “Amended Warrant”). The Amended Warrant amends the Original Warrant to provide that the Amended Warrant is subject to the same terms and conditions as the 2016 Warrants and, therefore, includes both cash and “cashless exercise” features and an Exchange Right whereby the number of shares issuable pursuant to the Exchange Right is equal to the “Amended Warrant Exchange Amount”, which is based on a Black Scholes option pricing model, and will be $941,197 , subject to adjustment to the extent that the risk-free U.S. treasury rate fluctuates between the date of issuance of the Amended Warrant and the date the Amended Warrant is exchanged. The Amended Warrant is exercisable for up to 1,161,972 shares of our common stock in the event we have obtained either of the Required Approvals with respect to the Amended Warrant. In the event the Amended Warrant holder exercises the Amended Warrant more than 90 days following the issuance of the Amended Warrant, if we have not obtained either of the Required Approvals, we will be required to pay the Amended Warrant holder an amount in cash for the shares of our common stock that we cannot issue under the Amended Warrant pursuant to such exercise without the Required Approvals based on the Amended Warrant Exchange Amount. The Amended Warrant also provides that, to the extent the closing bid price of our common stock on the second trading day prior to the date the Amended Warrant is exchanged is less than $0.50 , the Exchange Price will be deemed to be equal to $0.50 , and, in addition to issuing shares of our common stock based on this Exchange Price (assuming receipt of the Required Approvals), we will be required to pay to the Amended Warrant holder an amount in cash equal to the product obtained by multiplying (a) $0.50 minus the closing bid price of our common stock on the second trading day prior to the date the Amended Warrant is exchanged, by (b) the aggregate number of shares of our common stock issued to the Amended Warrant holder by us in such exchange at an Exchange Price equal to $0.50 . Therefore, if the Required Approvals are obtained, based on the Amended Warrant Exchange Amount of $941,197 (which, as noted above, is subject to adjustment to the extent that the risk-free U.S. Treasury rate fluctuates between the issuance of the Amended Warrant and the date the Amended Warrant is exchanged), the maximum number of shares of our common stock issuable pursuant to the Exchange Right in the Amended Warrant will be 1,882,395 . In addition, if, for example, assuming an Amended Warrant Exchange Amount of $941,197 , the closing bid price of our common stock on the second trading day prior to the date the Amended Warrant is exchanged is $0.25 , we would be required to pay to the Amended Warrant holder cash in an aggregate amount of $470,599 in addition to issuing the Amended Warrant holder 1,882,395 shares. In connection with entering into the SPA, we also entered into a Registration Rights Agreement, dated January 8, 2016, with the 2016 Investors. Pursuant to the terms of the Registration Rights Agreement, we were required to file with the SEC a registration statement to register for resale the shares of our common stock issuable upon conversion of the A-1 Preferred Shares and the shares of our common stock issuable upon exercise of the 2016 Warrants and the Amended Warrant by January 25, 2016. We filed the required registration statement with the SEC on January 25, 2016. Craig-Hallum (the “Placement Agent”) served as the sole placement agent for the January 2016 Offering. In consideration for services rendered as the Placement Agent in the January 2016 Offering, we (1) paid to the Placement Agent cash commissions equal to approximately $140,000 , or 7.0% of the gross proceeds received in the January 2016 Offering, excluding any proceeds received from Third Security, LLC or any of its affiliates; (2) issued to the Placement Agent, for a price of $50 , a five -year warrant to purchase up to 107,527 shares of our common stock at an exercise price of $1.21 per share (the “Agent Warrant”), which is subject to the same terms as the 2016 Warrants except that the Agent Warrant was not exercisable until July 8, 2016 and does not contain the Exchange Right; and (3) reimbursed the Placement Agent for reasonable out-of-pocket expenses, including fees paid to the Placement Agent’s legal counsel, incurred in connection with the January 2016 Offering, which reimbursable expenses did not exceed $50,000 . The January 2016 Offering and the payment of all accrued and unpaid dividends on the Series A Preferred Stock and Series B Preferred Stock in the form of shares of our common stock at a rate of $1.00 per share of our common stock discussed under “-Conversion of Preferred Stock” below required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the February 2012 common stock and warrant sale (the “2012 Private Placement”). The exercise price of these warrants decreased to $4.39 per share and the number of shares issuable upon exercise of the warrants increased from 2,188,177 to 3,239,827 . On May 31, 2016, we issued to a vendor an aggregate of 78,000 shares of our common stock and, on June 14, 2016, we issued to a second vendor an aggregate of 64,153 shares of our common stock. Such shares of common stock were issued to the vendors in lieu of an aggregate cash amount of approximately $89,000 owed by us to such vendors for services previously performed by such vendors. We issued the shares to the vendors in transactions exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws. The offering of the shares to the vendors did not involve a public offering, and no general solicitation or advertisement was made in connection with the offering of the shares to the vendors. On June 7, 2016, we entered into an At the Market Offering Agreement (the “ATM Agreement”) with Craig-Hallum, as sales agent, pursuant to which we may offer and sell, from time to time, through Craig-Hallum, up to $3,500,000 of shares (the “Shares”) of our common stock. Any Shares offered and sold in the offering will be issued pursuant to our effective shelf registration statement on Form S-3 (File No. 333-201907) and the related prospectus previously declared effective by the SEC on February 13, 2015, as supplemented by a prospectus supplement, dated June 7, 2016, that we filed with the SEC pursuant to Rule 424(b)(5) under the Securities Act of 1933, as amended (the “Securities Act”). The number of shares eligible for sale under the ATM Agreement will be subject to the limitations of General Instruction I.B.6 of Form S-3. Under the terms of the ATM Agreement, we will pay Craig-Hallum a placement fee of 3.25% of the gross sales price of the Shares, unless Craig-Hallum acts as principal, in which case we may sell Shares to Craig-Hallum as principal at a price to be agreed upon by us and Craig-Hallum. We will also reimburse Craig-Hallum for certain expenses incurred in connection with the ATM Agreement, and agreed to provide indemnification and contribution to Craig-Hallum with respect to certain liabilities, including liabilities under the Securities Act and the Securities Exchange Act of 1934, as amended. The ATM Agreement was terminated during the fourth quarter of 2016 and at the time of termination we had sold 1,177,849 shares. The average sales price per common share was $0.42 and the aggregate net proceeds from the sales totaled $0.5 million . We did not sell any shares under the ATM Agreement during the three month periods ended March 31, 2017 and 2016. The sale of shares under the ATM Agreement required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the 2012 Private Placement. The exercise price of these warrants decreased to $4.23 per share and the number of shares issuable upon exercise of the warrants increased from 3,262,088 to 3,362,276 . The 3,362,276 warrants issued in the 2012 Private Placement expired in February 2017. Common Stock Warrants. During the three months ended March 31, 2017 , we did not issue any warrants, no warrants were exercised and 3,362,276 warrants expired. During the three months ended March 31, 2016, we issued warrants to purchase 2,933,106 shares of common stock and no warrants were exercised. The warrants issued in the three months ended March 31, 2016 included 1,051,650 warrants issued due to repricing requirements of the Private Placement and 1,881,456 warrants issued in connection with the January 2016 Offering. Warrants to purchase an aggregate of 3,334,011 shares of common stock were outstanding at March 31, 2017 .

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 a Series A Convertible Preferred Stock Purchase Agreement (the “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 Stock 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 together 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 Series A financing were $6.0 million . The $0.2 million of costs incurred to complete the Series A 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 was preferred capital stock that was 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 Series A financing, we filed a Certificate of Designation of Series A Convertible Preferred Stock (the “Series A 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. As of December 31, 2013, the Series A Preferred Stock, including the Series A Preferred Stock issuable upon exercise of the Series A Warrants, was 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 Series A Certificate of Designation. Giving effect to the reverse split of our stock in January 2014, the conversion rate was adjusted to 1-for-3. Certain rights of the holders of the Series A Preferred Stock are senior to the rights of the holders of our 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, and which shall compound annually and shall be cumulative. In any calendar quarter in which we have positive distributable cash flow as defined in the Series A Purchase Agreement, we are required to pay from funds legally available a cash dividend in the amount equal to the lesser of 50% of such distributable cash flow or the aggregate amount of dividends accrued on the Series A Preferred Stock. 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 Series A 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, along with the holders of the Series B Preferred Stock, also are entitled to elect or appoint, as a single group, two directors of the Company. In connection with the Series A 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 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 stockholders’ meeting, vote to amend the Series A 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 stockholders’ equity as of the date of the Amendment Agreement. Preferred Stock Series B. On March 5, 2014, we entered into a Series B Convertible Preferred Stock Purchase Agreement (the “Series B Purchase Agreement”) with affiliates of Third Security, LLC (the “2014 Third Security Investors”), pursuant to which we, in a private placement, sold and issued an aggregate of 1,443,297 shares of our Series B Preferred Stock, par value $0.01 per share (the “Series B Preferred Stock”), at a price per share of $4.85 for an aggregate purchase price of approximately $7.0 million . Each share of Series B Preferred Stock issued pursuant to the Series B Purchase Agreement was initially convertible into shares of our common stock at a rate of 1 -for-1, which conversion rate was subject to further adjustment as set forth in the Certificate of Designation of Series B Convertible Preferred Stock. In connection with the Series B financing, we also entered into a Registration Rights Agreement, dated March 5, 2014, with the 2014 Third Security Investors, pursuant to which we granted certain demand, “piggy-back” and S-3 registrations rights covering the resale of the shares of common stock underlying the Series B Preferred Stock issued pursuant to the Series B Purchase Agreement and all shares of common stock issuable upon any dividend or other distribution with respect thereto. The Series B financing required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the Private Placement. The exercise price of the warrants decreased from $12.96 per share to $11.73 per share and the number of shares issuable upon exercise of the warrants increased from 1,097,600 to 1,212,665 . Conversion of Preferred Stock - Series A and Series B. On January 6, 2016, the Company entered into a Conversion Agreement (the “Conversion Agreement”) with the holders (the “Preferred Holders”) of all of the Company’s outstanding shares of Series A Convertible Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”), and Series B Preferred Stock, pursuant to which, among other things, the Preferred Holders: (a) elected to convert all of the outstanding shares of Series A Preferred Stock and Series B Preferred Stock into shares of our common stock, in each case in accordance with the terms thereof, and (b) agreed that all accrued and unpaid dividends on the Series A Preferred Stock and Series B Preferred Stock would be paid by the Company in shares of our common stock at a rate of $1.00 per share of our common stock (collectively, the “Conversion”). The outstanding shares of Series A Preferred Stock were convertible into shares of our common stock at a rate of 1 -for-3, and the outstanding shares of Series B Preferred Stock were convertible into shares of our common stock at a rate of 1-for-1. Prior to the entry into the Conversion Agreement, there were 2,586,205 shares of Series A Preferred Stock outstanding, which were converted into 862,057 shares of our common stock, and 1,443,297 shares of Series B Preferred Stock outstanding, which were converted into 1,443,297 shares of our common stock, for an aggregate of 2,305,354 shares of our common stock issued upon conversion of the Series A Preferred Stock and Series B Preferred Stock (the “Conversion Shares”). At the time of the entry into the Conversion Agreement, there were $3.7 million in accrued and unpaid dividends on the outstanding shares of Series A Preferred Stock, which were converted, in accordance with the Conversion Agreement, into 3,681,590 shares of our common stock, and $0.8 million in accrued and unpaid dividends on the outstanding shares of Series B Preferred Stock, which were converted, in accordance with the terms of the Conversion Agreement, into 793,235 shares of our common stock, for an aggregate of 4,474,825 shares of our common stock issued pursuant to the accrued and unpaid dividends on the Series A Preferred Stock and Series B Preferred Stock. Therefore, in connection with the full conversion of the Series A Preferred Stock and Series B Preferred Stock, plus the conversion of all accrued and unpaid dividends thereon, we issued an aggregate of 6,780,179 shares of our common stock to the Preferred Holders on January 6, 2016. Following the conversion of the shares of Series A Preferred Stock and Series B Preferred Stock into common stock, no shares of Series A Preferred Stock or Series B Preferred Stock remain outstanding. Preferred Stock Dividends. We had no undeclared dividends for the three months ended March 31, 2017. For the three months ended March 31, 2016, we had undeclared dividends. In accordance with the FASB’s Accounting Standards Codification Topic 260-10-45-11, “ Earnings per Share ”, these dividends were added to the net loss per share calculation. |
