Loan and Security Agreements

As of December 31, 2020, the Company had outstanding borrowings under a Loan and Security Agreement, as amended (the “2019 Loan”) with a financial institution (the “Lender”). On March 11, 2021, the Company entered into an

Amended and Restated Loan and Security Agreement, (the “2021 Revolver”), with the Lender to replace the 2019 Loan. This agreement created a revolving line of credit totaling $25.0 million and eliminated the existing term loan. Borrowings under the revolving line of credit bear interest at an annual rate equal to the greater of (i) one-half percent (0.5%) above the prime rate or (ii) 4.0% and mature on March 11, 2024. Borrowings are collateralized by substantially all of the Company’s property, excluding intellectual property, which is subject to a negative pledge. The 2021 Revolver subjects the Company to various customary covenants, including requirements as to financial reporting and financial covenants (including an unrestricted minimum cash level of $10.0 million), and restrictions on the Company’s ability to dispose of its business or property, to change its line of business, to liquidate or dissolve, to enter into any change in control transaction, to merge or consolidate with any other entity or to acquire all or substantially all the capital stock or property of another entity, to incur additional indebtedness, to incur liens on the Company’s property, to pay any dividends or make other distributions on capital stock other than dividends payable solely in capital stock, to redeem capital stock, to enter into in-bound licensing agreements, to engage in transactions with affiliates, and to encumber the Company’s intellectual property. Events of default under the 2021 Revolver include failure to make payments when due, insolvency events, failure to comply with covenants or material adverse events with respect to the Company. Upon the occurrence of an event of default and until such event of default is no longer continuing, the annual interest rate will be 5.0% above the otherwise applicable rate. As of December 31, 2021, the Company was in compliance with all financial covenants under the 2021 Revolver. The total long-term debt under the 2021 Revolver of $15 million is due in 2024.

The terms of the 2021 Revolver required that the existing term loan outstanding under the 2019 Loan be repaid with an advance under the line of credit. Accordingly, on March 11, 2021, the Company used $14.5 million of proceeds from the revolving line of credit to repay all amounts then due on the existing term loan. The Company accounted for the transaction as a debt extinguishment and recorded a loss on extinguishment of $0.2 million, which was included in interest expense in the condensed consolidated statements of operations and comprehensive loss.

In accordance with the applicable accounting standards, a short-term debt obligation should be excluded from current liabilities if the entity has both the intent and ability to refinance the obligation on a long-term basis. The intent and ability can be demonstrated by the issuance of a long-term obligation to refinance the short-term obligation on a long-term basis after the date of an entity’s balance sheet but before that balance sheet is issued. Due to the initial drawdown of the 2021 Revolver to repay the amount outstanding under the 2019 Loan, the Company classified $14.5 million of debt outstanding as of December 31, 2020 as long-term debt, net of current portion. Principal amounts totaling $0.5 million paid in the first quarter of 2021 prior to entering the 2021 Revolver were classified as current portion of long-term debt as of December 31, 2020.

Paycheck Protection Program Loan

On April 18, 2020, the Company issued a Promissory Note to Signature Bank, pursuant to which it received loan proceeds of $2.2 million (the “Loan”) provided under the Paycheck Protection Program established under the Coronavirus Aid, Relief, and Economic Security Act and guaranteed by the U.S. Small Business Administration (the “Paycheck Protection Program”). However, based on updated guidance related to this program, the Company repaid the Loan on May 4, 2020. The Loan was unsecured, was scheduled to mature on April 18, 2022, had a fixed interest rate of 1.0% per annum and was subject to the standard terms and conditions applicable to loans administered under the Paycheck Protection Program.
