Conversion price adjustment, description               The Company and certain investors agreed to amend the Convertible Unsecured Notes to reduce the conversion price from $2.50 per share of common stock to $0.25 per share of common stock, which conversion price was $0.10 lower than the closing price of the Company's common stock on such date. We evaluated the conversion price adjustment to determine whether the change should be recorded as a debt extinguishment or a modification of terms and determined that the price adjustment should be accounted for as a modification. The intrinsic value, or $0.10 per share of common stock, resulted in an additional beneficial conversion feature for the Convertible Unsecured Notes of $450,000.

Unsecured notes conversion, description       The Convertible Unsecured Notes are subordinate to the Senior Notes described in Note 8. The Convertible Unsecured Notes were initially convertible at the option of the holder into common stock at a conversion price of $4.31 per share and will automatically convert into shares of common stock in the event of a conversion of at least 50% of the then outstanding (i) principal, (ii) accrued and unpaid interest with respect to such principal and (iii) accrued and unpaid late charges, if any, with respect to such principal and interest, under the Senior Notes. In connection with the issuance of the 2016 Senior Notes and amendment and restatement of the 2015 Senior Notes, the conversion price was reduced to $2.50 per share.
