[2] Unamortized Discounts. Original issue discounts ("OID") are amortized to interest expense using the effective interest method. The unamortized discount represents the portion of OID that will be charged to interest expense over the remaining term of the respective debt agreements.

[3] Interest Rate. The stated interest rate is the contractual rate of interest specified in the debt agreement. For variable rate debt and amended debt agreements, the rate in effect as of March 31, 2016 is shown. For debt paid off during the three months ended March 31, 2016, the rate in effect on December 31, 2015 is shown. See also Note 7 for accounting for the fair value of compound embedded derivatives and detachable common stock purchase warrants that are bifurcated from the host debt agreement and accounted for at fair value.

[4] Credit Agreements. In April 2015, the Company entered into credit agreements with (i) Calm Waters Partnership ("Calm Waters"), an institutional investor and (ii) a group of 15 investors (the "Additional Lenders"), on substantially identical terms, pursuant to which Calm Waters made term loans to the Company of $35,000 and the Additional Lenders made term loans of $6,214 (collectively referred to as the "April Term Loans"). In June 2015, the Company and Calm Waters entered into an amendment that provided for an additional term loan (the "June Term Loan") for $6,000. In October 2015, the Company and Calm Waters entered into an amendment that provided for an additional term loan (the "October Term Loan") for $18,000. In January 2016, the Company and Calm Waters entered into an amendment that provided for an additional term loan of $9,043 (the "January Term Loan"). The April, June, October and January Term Loans mature in April 2018 and bear interest at the rate of 12.0% per annum.

[5] Convertible to Common Stock. The outstanding principal balance and accrued interest of the Convertible Debt is convertible to shares of the Company's common stock. Additional details about outstanding convertible debt agreements are summarized in Note 6(c).

[6] VIP Promissory Notes. In April 2014, the Company issued $11,000 of promissory notes (the "VIP Promissory Notes") in connection with the acquisition of VIP. The VIP Promissory Notes provided for interest at 10.0% and matured in December 2014. During 2014, additional consideration of $5,000 was also due under an earnout provision in the acquisition agreement. In April 2015, the VIP Promissory Notes were amended whereby the Company agreed to combine the $5,000 earnout (which provides for interest at 3.5% per annum) into the VIP Promissory Notes. Under the amended terms, the Company agreed to make principal payments of (i) $8,000 in April 2015, (ii) $300 per month from October 2016 through November 2017, and (iii) accrued interest and any remaining principal balance is payable in December 2017. In addition, the Company made a principal payment of $100 in January 2015, $500 in October 2015 and $270 in January 2016 as a concession to obtain the January Term Loan discussed above, resulting in an outstanding principal balance of $7,130 as of March 31, 2016.

The principal amount of the Unsecured Note is payable in twelve equal monthly installments of $150 on the first business day of each month from April 2015 through March 2016. The Unsecured Note was paid off at maturity.
