The Company issued $32,500 aggregate principal amount of Debentures (June 2015 Debentures) that, subject to certain ownership limitations and stockholder approval conditions, will be convertible into 43,333,334 shares of Company common stock at an initial conversion price of $0.75 per share. The Debentures bear interest at the rate of 2.25% per year, and, unless previously converted, will mature on the five-year anniversary of the date of issuance, June 22, 2020. Under the terms of the Debentures and the June 2015 Warrants (noted above), the issuances of shares of the common stock upon conversion of the Debentures and upon exercise of the Warrants were subject to stockholder approval of such issuances and an amendment to the Company's certificate of incorporation to increase the Company's authorized shares of common stock. The Company received stockholder approval for these proposals, at the annual stockholders meeting held September 30, 2015.

The June 2015 Debentures include a beneficial conversion feature of $27,300 that was recorded as a discount to the debenture. On the date of issuance the beneficial conversion feature value was calculated as the difference resulting from subtracting the conversion price of $0.75 from $1.38, the opening market value of the Company's common stock following the announcement of the transaction, multiplied by the number of common shares into which the June 2015 Debentures are convertible. This discount will be amortized over the five year life of the Debentures. The embedded conversion feature contains an anti-dilution provision that allows for downward exercise price adjustments in certain situations. The embedded conversion feature was not bifurcated as it did not meet all of the elements of a derivative.

On July 21, 2014, the Company entered into a definitive Securities Purchase Agreement (the "Purchase Agreement") with institutional investors (the "Investors") providing for the issuance of Senior Secured Convertible Debentures in the aggregate principal amount of $15,000, due, subject to the terms therein, in July 2019 (the "July 2014 Debentures"), and warrants (the "July 2014 Series A Warrants") to purchase up to an aggregate of 6,198,832 shares of common stock, $0.001 par value per share, at an exercise price of $2.45 per share expiring in July 2019. The Debentures bear interest at an annual rate of 4%, payable quarterly or upon conversion into shares of common stock. The Debentures are convertible at any time into an aggregate of 5,847,955 shares of common stock at an initial conversion price of $2.565 per share. The Company's obligations under the Debentures are secured by a first priority lien on all of the Company's intellectual property pursuant to the terms of a security agreement ("Security Agreement") dated July 21, 2014 among the Company and the Investors. In connection with the Purchase Agreement, the Company entered into a Registration Rights Agreement with the Investors pursuant to which the Company was obligated to file a registration statement to register for resale the shares of Common Stock issuable upon conversion of the Series B Preferred Stock (See Note 11) and Debentures and upon exercise of the Warrants. Under the terms of the Registration Rights Agreement, the Company filed a registration statement on August 19, 2014, which was declared effective by the SEC on October 20, 2014 (File No. 333-198249). Proceeds from the Debentures are being used for general working capital purposes.

For financial reporting purposes, the $15,000 funded by the Investors on July 21, 2014 was allocated first to the fair value of the obligation to issue the Warrants, amounting to $5,296, then to the intrinsic value of the beneficial conversion feature on the Debentures of $4,565. The balance was further reduced by the fair value of warrants issued to the placement agent for services rendered of $491, resulting in an initial carrying value of the Debentures of $4,647. The initial debt discount on the Debentures totaled $10,353 and is being amortized using the effective interest method over the five year life of the Debentures.

During the nine months ended September 30, 2015, the investors converted debentures amounting to $4,593 into 1,790,671 shares of common stock. The debt discount and deferred financing cost adjustment resulting from the conversions increased interest expense by $3,415 for the nine months ended September 30, 2015. As of September 30, 2015, the total outstanding amount of Debentures was $41,317.
