[1] In addition to the principal balance shown, certain debt agreements provide for prepayment penalties up to 25% if the debt is repaid prior to the maturity date.

[2] As of June 30, 2015, the Company has 300,000,000 common shares authorized of which 70,482,486 were issued and outstanding. The Company would need approximately 330,000,000 common shares to accommodate the exercise and conversion of all of the common stock options, warrants, convertible debt, and unvested restricted stock presently outstanding, and would not be able to accommodate all such exercise and conversion requests through the remaining unissued common shares. Accordingly, the Company could be required to settle a portion of its warrants and derivative liabilities in cash which requires that they continue to be classified as liabilities rather than equity instruments.

[3] Certain of the debt instruments summarized in Note 7 contain features that permit the holders to elect conversion of the debt to shares of the Company's Common Stock. The Company bifurcates the conversion features from the related debt instruments and accounts for each component at its estimated fair value with updated valuations performed at the end of each calendar quarter.

[4] As of December 31, 2014, the aggregate principal balance (exclusive of unamortized discounts of $2,511) of these notes was $25,455 and the stated interest rate was 15.0%. During the first quarter of 2015, holders of $20,150 principal amount agreed to amend their notes to (i) extend the maturity date by 18 months from the original maturity dates in January and February 2015, (ii) reduce the interest rate from 15.0% to 8.0%, and (iii) reset the conversion price between $0.45 and $0.75 per share and eliminate all conversion price adjustments after the amendment. Additionally, between February and April 2015, holders of $1,858 principal amount converted their notes and accrued interest into 3,314,166 shares of the Company's common stock, and holders of $3,375 principal amount agreed to exchange their notes for 10% exchange convertible notes. Additionally, holders of the 34,939,928 warrants issued in the first quarter of 2014 in connection with the Senior Secured Notes private placement agreed to amend their warrants to (i) remove the adjustment provisions stemming from any subsequent issuances, (ii) add a cashless exercise provision and (iii) set the exercise price at either $1.01 or $0.45. See Note 8 for further information on the Company's warrants.

[5] The outstanding principal balance and accrued interest are convertible to shares of the Company's common stock. The stated conversion price gives effect to amendments to the respective debt agreements and represents the conversion prices in effect on June 30, 2015. For debt repaid or extinguished during the six months ended June 30, 2015, the conversion price in effect on December 31, 2014 is shown. The conversion price is subject to adjustment upon certain events, such as stock splits, combinations, dividends, distributions, reclassifications, mergers or other corporate change and dilutive issuances.

[6] Under certain conditions for a period of one year from the date of the respective financing transaction, the lenders may elect to participate in future financings on the same terms, conditions and price provided for in such subsequent financing.
