Note Payable

In June 2015, the Company entered into a loan and security agreement, as amended, (“Agreement”) with a commercial bank. The Agreement allowed for borrowings of up to $3.5 million. Outstanding borrowings under the Agreement bore interest at the prime rate of interest plus 0.5%, or 3.62% at December 31, 2020. This note payable was paid in full in March 2021 with the proceeds from the Loan Agreement and the restriction on the Company’s cash was lifted. Prior to repayment, the Company was required to maintain at least $2.0 million in an account with and under the control of the commercial bank, that reduced in line with the loan balance once the loan balance declined below $2.0 million. As of December 31, 2020, the outstanding balance due on the note payable was $2.9 million.

Outstanding borrowings under the Agreement were secured by substantially all assets of the Company, and the Company was required to maintain certain financial and non-financial covenants. The Company was in compliance with all covenants at December 31, 2020.

In October 2018, in connection with the issuance of Series A convertible preferred stock (Note 8), the Company cancelled warrants previously issued to the commercial bank and issued in its place warrants to purchase 234 and 91 shares of common stock. The warrants have an exercise price of $96.24 per share and $106.17 per share, are immediately exercisable and expire in June 2025 and July 2027, respectively.

Subordinated Note Payable

In May 2017, the Company entered into a loan and security agreement, as amended, (“Sub Agreement”) with a lending institution for borrowings of up to $10.0 million. Outstanding borrowings under the Sub Agreement bore interest at the rate of 12% per year. Pursuant to the Sub Agreement, a final payment of $0.7 million was payable at the maturity date in April 2023. The Company recorded the final payment as both a discount and an increase to the principal amount of the debt. The Company also capitalized certain lender and legal costs associated with the Sub Agreement totaling $0.3 million, which were recorded as a discount to the Sub Agreement. The aggregate discount of $1.2 million was being amortized to interest expense over the repayment term of the Sub Agreement. At December 31, 2020, the remaining unamortized discount was $0.2 million. The Company amortized $0 and $83,000 of the discount to interest expense during the three months ended September 30, 2021, and 2020, respectively, and $34,000 and $0.2 million for the nine months ended September 30, 2021, and 2020, respectively.

Borrowings under the Sub Agreement were paid in full in March 2021 with the proceeds from the Loan Agreement. As a result, the Company recorded a loss on debt extinguishment within interest expense totaling $0.2 million, which includes writing off the remaining unamortized debt discount of $0.2 million plus lender fees paid to extinguish the debt.

Outstanding borrowings under the Sub Agreement were collateralized by substantially all assets of the Company and were subordinate to any outstanding borrowings under the Agreement. Borrowings under the Sub Agreement were subject to certain financial and non-financial covenants. The Company was in compliance with all covenants at December 31, 2020.

Paycheck Protection Program (PPP Loan)

On April 11, 2020, the Company entered into an original loan agreement with East West Bank as the lender for a loan in an aggregate principal amount of $2.2 million (“PPP Loan”) pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) and implemented by the U.S. Small Business Administration. The PPP Loan matures in two years and bears interest at a rate of 1% per year, with all payments deferred through the six-month anniversary of the date of the PPP Loan. Principal plus accrued unpaid interest is to be paid in one payment two years after the date of this note and may be prepaid by the Company at any time prior to maturity without penalty. The Company may apply for forgiveness of amounts due under the PPP Loan, with the amount of potential loan forgiveness to be calculated in accordance with the requirements of the CARES Act based on payroll costs, any mortgage interest payments, any covered rent payments and any covered utilities payments during the 8-24 week period after the origination date of the Loan. The Company used proceeds of the Loan for payroll and other qualifying expenses.

On November 19, 2020, the Company applied for forgiveness of the full principal amount. On August 9, 2021, the Company received notification that the full amount of the PPP Loan and accrued interest was forgiven. As a result, the Company recorded a gain from the forgiveness of the PPP Loan in the condensed consolidated statements of operations and comprehensive loss during the three months ended September 30, 2021.

The first tranche of $15.0 million was funded on March 31, 2021. The second tranche of $2.0 million is available, at the Company’s request, between October 30, 2021, and November 30, 2021, provided the Company achieves at least $6.0 million in revenue and a maximum EBITDA loss of $4.8 million, in each case for the third fiscal quarter of 2021. Outstanding borrowings under the Loan Agreement are secured by a first priority lien on substantially all of the personal property assets of the Company, including the Company’s intellectual property. The Company is required to pay only interest during the first 18 months after funding of the tranche and thereafter, the Company shall repay such loan amount in 30 consecutive equal monthly installments of principal plus accrued interest. The loan facility bears an annual interest rate of the prime rate as published in the Wall Street Journal, subject to a floor 3.25%, plus 8.75%. On the final repayment date, Company is also obligated to pay a final payment fee equal to seven and one-half percent (7.5%) of the amount of the applicable advance.

As of September 30, 2021, the outstanding balance on the loan has been classified as a long-term liability in the loan payable in the accompanying condensed consolidated balance sheet.
