(“Hercules”). The Payoff Amount includes a prepayment charge of $100,000 equal to 1.0% of the outstanding principal, and an exit fee of $395,000. Upon receipt by Hercules of the Payoff Amount on May 1, 2023, all obligations, covenants, debts and liabilities of the Company under the Loan Agreement were satisfied and discharged in full, and the Loan Agreement and all other documents entered into in connection with the Loan Agreement were terminated.

The Loan Agreement provided for a term loan with aggregate maximum borrowings of up to $30.0 million (the “Term Loan”). Under the Loan Agreement, the Company borrowed $10.0 million. The Term Loan bore interest at a variable annual rate equal to the greater of either (i) the sum of (a) 6.30% plus (b) the prime rate (as reported in the Wall Street Journal on the last business day of the month that immediately precedes the month in which the interest will accrue) or (ii) 9.55%. Interest-only payments on the borrowings under the Loan Agreement were due through May 1, 2023.
