Stockholders' Equity Note [Abstract] |
STOCKHOLDERS' EQUITY | STOCKHOLDERS’ EQUITY 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 February 2, 2012, we entered into definitive agreements with institutional and other accredited investors and raised approximately $22.0 million in a private placement financing (the “Private Placement”), which included an aggregate of $3.0 million in convertible notes issued in December 2011 to entities affiliated with Third Security, LLC, a related party, that automatically converted 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 1,583,333 shares of our common stock at a price per share of $12.00, as well as five-year warrants to purchase up to an aggregate of 823,333 shares of our common stock with an exercise price of $15.00 per share. In connection with the conversion of the convertible notes issued by us to the entities affiliated with Third Security, LLC, the entities received an aggregate of 250,000 shares of our common stock and 125,000 warrants on the same terms as all investors in the Private Placement. Craig-Hallum Capital Group LLC served as the sole placement agent for the offering. In consideration for services rendered as the placement agent in the offering, we agreed to (a) pay to the placement agent cash commissions equal to $1,330,000, or 7.0% of the gross proceeds received in the offering; (b) issue to the placement agent a five-year warrant to purchase up to 31,666 shares of our common stock (representing 2% of the shares sold in the Private Placement) with an exercise price of $15.00 per share and other terms that are the same as the terms of the warrants issued in the Private Placement; and (c) reimburse the placement agent for reasonable out-of-pocket expenses, including fees paid to the placement agent’s legal counsel, incurred in connection with the offering, which reimbursable expenses were not to exceed $125,000. 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 were used for general corporate and working capital purposes, primarily to accelerate development of several of our key initiatives. On January 24, 2013, we entered into a Securities Purchase Agreement with certain institutional and other accredited investors pursuant to which we: (a) sold to the investors an aggregate of 1,383,333 shares of our common stock at a price per share of $6.00 for aggregate gross proceeds of approximately $8.3 million; and (b) issued to the investors warrants to purchase up to an aggregate of 691,655 shares of our common stock with an exercise price of $9.00 per share (the “Offering”). The warrants may be exercised, in whole or in part, at any time from January 30, 2013 until January 30, 2018 and contain both cash and “cashless exercise” features. Affiliates of Third Security, LLC purchased an aggregate of 500,000 shares of common stock and warrants to purchase an aggregate of 250,000 shares of common stock in the Offering on the same terms as the other investors. Net proceeds from the Offering were used for general corporate and working capital purposes. In connection with the Offering, we entered into a registration rights agreement with the investors (the “Registration Rights Agreement”). The Registration Rights Agreement required that we file with the Securities and Exchange Commission (the “SEC”) a registration statement to register for resale the shares of common stock sold and the shares of common stock issuable upon exercise of the warrants (the “Warrant Shares”) by March 16, 2013. The registration statement was filed with the SEC on March 15, 2013 and was declared effective by the SEC on March 29, 2013. The Offering 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 $15.00 per share to $12.96 per share and the number of shares issuable upon exercise of the warrants increased from 948,333 to 1,097,600. On October 22, 2014, we entered into a Securities Purchase Agreement with certain accredited investors (the “October 2014 Investors”), pursuant to which we, in a private placement, issued and sold to the October 2014 Investors (the “2014 Private Placement”) an aggregate of 730,776 shares of our common stock at a price per share of $3.25 for an aggregate purchase price of approximately $2.4 million, and warrants to purchase up to an aggregate of 365,388 shares of our common stock with an initial exercise price of $4.00 per share that are exercisable for the period from April 22, 2015 through April 22, 2020. In connection with the 2014 Private Placement, we also issued a warrant to purchase up to an aggregate of 9,230 shares of our common stock to one advisor. The warrants issued in the 2014 Private Placement include both cash and “cashless exercise” features. The 2014 Private Placement 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 exercise price of the warrants decreased from $11.73 per share to $10.86 per share and the number of shares issuable upon exercise of the warrants increased from 1,212,665 to 1,309,785. On December 31, 2014, we entered into the Note Purchase Agreement with the Investor pursuant to which we agreed to issue and sell the Initial Note to the Investor (the “Note Private Placement”). See Note 5 - “Debt-Convertible Promissory Notes” for additional information regarding the terms of the Initial Note. Pursuant to the terms of the Note Purchase Agreement, we are subject to certain registration obligations and we may be required to effect one or more other registrations to register for resale the shares of our common stock issued or issuable under the Initial Note in connection with certain “piggy-back” registration rights granted to the Investor. The Note Private Placement 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 exercise price of the 2012 warrants decreased from $10.86 per share to $10.25 per share and the number of shares issuable upon exercise of the warrants increased from 1,309,785 to 1,387,685. On January 15, 2015, we entered into the Note Purchase Agreement with the Additional Investors and, on January 20, 2015, issued and sold to the Additional Investors, in a private placement, the Additional Notes in an aggregate principal amount of $925,000 (the “Additional Note Private Placement”). The Additional Notes have the same terms and conditions as the Initial Note. Craig-Hallum acted as the sole placement agent for the sale and issuance of the Additional Notes. In connection with the sale and issuance of the Additional Notes, we issued to Craig-Hallum an unsecured convertible promissory note, upon the same terms and conditions as the Notes, in an aggregate principal amount equal to 5% of the proceeds received by us pursuant to the sale and issuance of the Additional Notes, or $46,250. As of the date of filing of this Quarterly Report on form 10-Q, the Placement Agent Note remains outstanding. The Additional Note Private Placement required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the Private Placement. The exercise price of these warrants decreased from $10.25 per share to $9.59 per share and the number of shares issuable upon exercise of the warrants increased from 1,387,685 to 1,483,161. On February 27, 2015, we entered into a purchase agreement with Craig-Hallum Capital Group LLC (the “Underwriter”) relating to our sale and issuance of 3,573,899 shares of our common stock and corresponding warrants to purchase up to 714,780 shares of our common stock (the “2015 Offering”). Each share of common stock was sold in combination with a warrant to purchase 0.20 of a share of common stock. The purchase price to the public for each share of common stock and accompanying warrant was $1.95. The purchase price paid by the Underwriter to us for the common stock and accompanying warrants was $1.8135. The net proceeds from the 2015 Offering, after deducting the Underwriter’s discount and other estimated 2015 Offering expenses, were approximately $6.2 million. The accompanying warrants are exercisable immediately upon their initial issuance date at an exercise price of $2.24 per share and will expire five years from the date of issuance. The exercise price will also be subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock. The 2015 Offering required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the Private Placement. The exercise price of these warrants decreased from $9.59 per share to $7.56 per share and the number of shares issuable upon exercise of the warrants increased from 1,483,161 to 1,881,396. On June 30, 2015, we entered into a Securities Purchase Agreement with certain accredited investors (the “July 2015 Investors”) pursuant to which, on July 7, 2015, we sold to the July 2015 Investors, and the July 2015 Investors purchased from us, (a) an aggregate of approximately 1.5 million shares of our common stock at a price per share of $1.42, (b) warrants (the “Series B Warrants”) to purchase up to an aggregate of 0.7 million shares of our common stock with an exercise price of $0.01 per share, and (c) warrants (the “Series A Warrants” and, together with the Series B Warrants, the “July 2015 Warrants”) to purchase up to an aggregate of 1.2 million shares of our common stock, with an exercise price of $1.66 per share (collectively, the “July 2015 Offering”). The purchase price for the Series B Warrants was $1.42 per share of our common stock subject to the Series B Warrants. Each of the July 2015 Warrants has a term of 5 and 1/2 years. The Series B Warrants were immediately exercisable upon issuance. The Series A Warrants became exercisable on January 7, 2016, six months from the date of issuance. The aggregate gross proceeds to us from the July 2015 Offering were approximately $3.0 million. Craig-Hallum Capital Group LLC (the “2015 Placement Agent”) served as the sole placement agent for the Offering. In consideration for services rendered as the placement agent in the July 2015 Offering, we (a) paid to the 2015 Placement Agent cash commissions equal to approximately $212,783, or 7.0% of the gross proceeds received in the July 2015 Offering; (b) issued to the 2015 Placement Agent a five-year warrant to purchase up to 107,033 shares of our common stock with an exercise price of $1.66 per share and which is subject to other terms that are the same as the terms of the Series A Warrants; and (c) reimbursed the 2015 Placement Agent for reasonable out-of-pocket expenses, including fees paid to the 2015 Placement Agent’s legal counsel, incurred in connection with the July 2015 Offering, which reimbursable expenses did not exceed $50,000. The July 2015 Offering required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the Private Placement. The exercise price of these warrants decreased from $7.56 per share to $6.50 per share and the number of shares issuable upon exercise of the warrants increased from 1,881,396 to 2,188,177. On January 6, 2016, the Company entered into a Securities Purchase Agreement (the “SPA”) with certain accredited investors (the “Investors”), pursuant to which, on January 8, 2016, the Company sold to the Investors, and the Investors purchased from the Company (the “January 2016 Offering”), an aggregate of approximately $2.2 million of units (the “Units”) consisting of (1) an aggregate of 2,365,243 shares (the “A-1 Preferred Shares”) of Series A-1 Convertible Preferred Stock, par value $0.01 per share, of the Company (the “A-1 Preferred”), and (2) warrants (the “Warrants”) to purchase up to an aggregate of 1,773,929 shares of our common stock. Each Unit was sold to the 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 the Company’s 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”). 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: (a) 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 (b) 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. The 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 Warrant includes both cash and “cashless exercise” features and an exchange feature whereby the holder of the Warrant may exchange (the “Exchange Right”) all or any portion of the 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 Warrant is exchanged (the “Exchange Price”). Under the Warrants, the “Exchange Amount” is based upon a Black Scholes option pricing model, and the aggregate Exchange Amount under all of the Warrants will be $1,436,882, subject to adjustment to the extent that the risk-free U.S. Treasury rate fluctuates between the date of issuance of the Warrants and the date the Warrants are exchanged. Each 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 Warrant, unless the Company has 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 Warrants, if the Company has not obtained either of the Required Approvals, the Company will be required to pay the Warrant holder an amount in cash for any Additional Shares that it cannot issue without the Required Approvals based on the Exchange Amount. The 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 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, the Company will be required to pay to the 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 Warrant is exchanged, by (b) the aggregate number of shares of our common stock issued to the 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 Warrants and the date the Warrants are exchanged), the maximum number of shares of our common stock issuable pursuant to the Exchange Right in the 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 Warrants are exchanged is $0.25, the Company would be required to pay to the Warrant holders cash in an aggregate amount of $718,441 in addition to issuing the Warrant holders 2,873,765 shares. In accordance with the terms of the SPA, the Company amended that certain Series A Warrant to purchase up to an aggregate of 1,161,972 shares of our common stock previously issued by the Company to an affiliate of one of the Investors on July 7, 2015 (the “Original Warrant”), as previously reported by the Company on its 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 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 the Company has 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 the Company has not obtained either of the Required Approvals, the Company will be required to pay the Amended Warrant holder an amount in cash for the shares of our common stock that the Company 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), the Company 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 the Company 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, the Company 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, the Company also entered into a Registration Rights Agreement, dated January 8, 2016, with the Investors. The Registration Rights Agreement requires that the Company 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 (the “A-1 Preferred Conversion Shares”) and the shares of our common stock issuable upon exercise of the Warrants and the Amended Warrant (collectively, the “Warrant Shares”) by January 23, 2016. Craig-Hallum Capital Group LLC (the “Placement Agent”) served as the sole placement agent for the Offering. In consideration for services rendered as the Placement Agent in the Offering, the Company (1) paid to the Placement Agent cash commissions equal to approximately $140,000, or 7.0% of the gross proceeds received in the 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 Warrants except that the Agent Warrant is 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 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 Private Placement. The exercise price of these warrants decreased from $6.50 per share 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. Common Stock Warrants. During the three months ended March 31, 2016 and 2015, we issued warrants to purchase 2,933,106 and 1,208,491 shares of common stock, respectively. None of the issued warrants were exercised during such periods. 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 Offering, which was completed in January 2016. The warrants issued in the three months ended March 31, 2015 included 493,711 warrants issued due to repricing requirements of the Private Placement and 714,780 warrants issued in connection with the 2015 Offering. Warrants to purchase an aggregate of 8,853,905 shares of common stock were outstanding at March 31, 2016.

Issuance of Series B Preferred Stock. 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. 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: (1) 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 (2) 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 $3,681,591.90 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 $793,236.17 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 (the “Dividend Shares”). 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, the Company 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 cumulative undeclared dividends on our Series A Preferred Stock and Series B Preferred Stock (collectively “Preferred Stock”) of zero and $4.4 million at March 31, 2016 and December 31, 2015, respectively. Since dividends should generally not be recognized as a liability until declared, we had a recorded liability of zero for these undeclared dividends at December 31, 2015. For the three months ended March 31, 2016 and 2015, 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.
