Loan Agreement with Hercules Capital, Inc.

On February 18, 2016, the Company entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc. (the “Lender”) under which the Company borrowed $7.5 million upon the execution of the Loan Agreement on February 18, 2016. The interest rate applicable to each tranche was variable based upon the greater of either (i) 9.2% and (ii) the sum of (a) the Prime Rate as reported in The Wall Street Journal minus 3.5%, plus (b) 9.2%. Payments under the Loan Agreement were interest only until June 1, 2017, followed by equal monthly payments of principal and interest through the maturity date of September 1, 2019. The Company paid the Lender aggregate facility fees of $0.2 million in connection with the Loan Agreement.

In connection with the Loan Agreement, the Company issued warrants to the Lender, which are exercisable for 9,005 shares of common stock at a per share exercise price of $33.31 (the “Hercules Capital Warrants”). The Hercules Capital Warrants will terminate, if not earlier exercised, on February 18, 2026. The fair value of the Hercules Capital Warrants was recorded at inception as a redeemable convertible preferred stock warrant liability upon issuance.

On September 3, 2019, the Company repaid the remaining outstanding loan balance of $2.6 million and an associated accrued interest and aggregate end-of-term payment of $0.6 million, and the Loan Agreement was terminated. At the effective time of the Merger, the warrant liability was reclassified to equity in the condensed consolidated balance sheets. As of June 30, 2020, there were no remaining unaccreted debt discounts and issuance costs.

Paycheck Protection Program

On April 15, 2020, the Company executed an unsecured promissory note (referred to in the condensed consolidated financial statements as of and for the six months ended June 30, 2020 as a “note payable”) to IberiaBank (the “PPP Loan”) pursuant to the U.S. Small Business Administration’s Paycheck Protection Program (the “PPP”) under Division A, Title I of the federal Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. A PPP loan is for the purpose of helping businesses keep their workforce employed during the Coronavirus (COVID-19) crisis. The Company is using the PPP Loan proceeds for covered payroll costs and certain other permitted costs in accordance with the relevant terms and conditions of the CARES Act.

The PPP Loan is in the principal amount of $0.4 million, bears interest at a fixed rate of 1.00% per annum and matures on April 15, 2022. The PPP Loan requires equal monthly payments of principal and interest commencing on November 15, 2020. The PPP Loan may be prepaid by the Company at any time prior to maturity without penalty. Under the terms of the PPP Loan, the Company is evaluating whether it may apply for forgiveness of the amount due on the PPP Loan.
