In addition, the Loan Agreement required a Final Payment Fee (as defined in the Loan Agreement) equal to one-percent of the aggregate principal amount borrowed, or $0.1 million.

Paycheck Protection Loan

In April 2020, the Company obtained a $1.1 million loan through the Bank under the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), as amended. The loan’s purpose was to maintain payroll and make rent and utilities payments as specified under the terms of the PPP. Under the PPP, borrowers may apply for loan forgiveness if the funds are used for payroll costs, mortgage interest, rent, and utilities payments over a specified term following receipt of the loan funds. During the term of the agreement, the Company utilized the loan funds for forgivable purposes and applied for forgiveness. In June 2021, the outstanding $1.1 million PPP loan was forgiven and removed from the Company’s balance sheet. As a result of the forgiveness of the PPP loan, a $1.1 million gain on extinguishment was recorded in other income (expense), net for the year ended December 31, 2021.
