Long-Term Debt

Riley Loan— On October 26, 2017 (the “Effective Date”), the Company entered into a Subordinated Term Loan and Security agreement (the “Loan Agreement”) with B. Riley Principal Investments, LLC (“BRPI”), an affiliate of B. Riley Financial, Inc., a shareholder of the Company. Under the original Loan Agreement, the Company could borrow principal up to $10,000 via a subordinated secured convertible promissory note (the “Convertible Note”), with an optional conversion feature as described below.

During the year ended December 31, 2018, the Company amended the Loan Agreement to increase the available aggregate principal borrowings to $12,000. The 2018 amendments did not change the terms of the original Loan Agreement other than to provide a waiver of the defined prepayment penalties if any repayment does not reduce the principal amount outstanding below $10,000. The Loan Agreement, as amended, matures on September 1, 2022 (the “Maturity Date”) and carries a stated interest rate of 10% and provided that the first year of interest be compounded into the principal on October 26, 2018, with interest-only payments beginning thereafter.

As of both March 31, 2019 and December 31, 2018, the total outstanding borrowings under the Loan Agreement, as amended, was $12,000 and total accrued interest outstanding was $1,001.

Optional Conversion— On November 2, 2018, in conjunction with the Company’s conversion of all of its outstanding shares of preferred stock into shares of common stock (See Note 6) and the 15-to-1 reverse stock split, the Company amended the optional conversion terms of its existing Convertible Note. As amended the Convertible Note provides that at any time, on or prior to the Maturity Date, BRPI may elect to convert principal amounts outstanding, including accrued interest, as limited below, into shares of common stock at $8.87 per share. The number of shares of common stock to be issued upon conversion is limited to the sum of (A) the lesser of (i) the principal outstanding and (ii) the aggregate principal amount borrowed under the Loan Agreement to date multiplied by the Designated Percentage as described below, and (B) accrued interest. The “Designated Percentage” is one hundred percent (100%) if the conversion date is prior to the first anniversary of the Effective Date, seventy-five percent (75%) in Year 2 of the Loan Agreement, fifty percent (50%) in Year 3, twenty-five percent (25%) in Year 4, and twelve and a half of percent (12.5%) in the final year of the Loan Agreement on or prior to the Maturity Date.

Promissory Notes Payable—In 2014 and 2017, the Company entered into agreements with one of its suppliers, whereby certain of its trade payables for royalties and royalty up-front payments were converted to payment plans. In December 2018, the Company amended its accounts payable financing agreements, effective January 1, 2019, which provides for the $736 outstanding balance to be paid in twenty equal quarterly installments. The amounts due under these agreements would be paid in quarterly installments over periods from two to four years, with interest ranging up to 8%.
