NOTE 6 —Borrowings

Long-Term Debt

Riley Loan— The Company had a Subordinated Term Loan and Security Agreement, as amended, (the “B. Riley Loan Agreement”) with B. Riley Principal Investments, LLC (“BRPI”), an affiliate of B. Riley Financial, Inc., a shareholder of the Company. Under the amended B. Riley Loan Agreement, the Company could borrow principal up to $12,000 via a subordinated secured convertible promissory note, with an optional conversion feature.

The amended B. Riley Loan Agreement included repayment penalties if any repayment reduced the principal amount outstanding below $10,000. The prepayment penalty was 2% for 2019 and decreased to 1% after the second anniversary through maturity. The borrowings under the B. Riley Loan Agreement, as amended would have matured on September 1, 2022, and carried a stated interest rate of 10% and provided that the first year of interest commencing on October 26, 2018, was compounded into the principal, with interest-only payments beginning thereafter.

On June 1, 2020, the Company entered into a Note Amendment and Debt Cancellation Agreement with BRPI (the “Note Amendment”), which provided that, contingent upon the closing of the PO, the Company would repay $4,000 of the outstanding indebtedness to BRPI in cash (the “B. Riley Repayment”) and the remaining principal amounts, accrued interest and other amounts outstanding under the B. Riley Loan Agreement, after giving effect to the B. Riley Repayment, would be redeemed for shares of common stock to be issued to BRPI or its affiliates at the public offering price of shares of common stock in the PO.

Pursuant to the Note Amendment, as amended, the Company made the B. Riley Repayment on June 9, 2020, and the remaining principal amount, accrued interest and other amounts outstanding under the B. Riley Loan Agreement, after giving effect to the B. Riley Repayment, in the amount of $6,170, was redeemed into 822,682 shares of the Company’s common stock issued to BRPI and BRC Opportunity Fund L.P., an affiliate of BRPI, (the “Redemption Shares”). Following the B. Riley Repayment and the issuance of the Redemption Shares, the Company has no outstanding indebtedness under the B. Riley Loan Agreement. Also, on June 11, 2020, the Company entered into a registration rights agreement with BRPI and BRC Partners Opportunity Fund, L.P. pursuant to which the Company agreed to file a registration statement covering the resale of the Redemption Shares and to use its best efforts to cause such registration statement to become effective upon the time frames set forth in the registration rights agreement. A registration statement on Form S-3 (File No. 333-239664) registering the Redemption Shares for resale by BRPI and BRC Partners Opportunity Fund, LP was declared effective by the SEC on July 13, 2020.

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%. Remaining balances are $214 and $362 at December 31, 2021 and 2020, respectively.

PPP Loan--On April 13, 2020, the Company received approximately $2.3 million in PPP loan proceeds. Following additional guidance issued by the SBA on April 23, 2020, that casted doubt on the ability of public companies to qualify for loans under the PPP, the Company repaid the PPP loan on April 29, 2020.

The components of the long-term debt balance as of December 31, are as follows:
