On May 27, 2026, Viridian Therapeutics, Inc. (the "Company") completed a voluntary prepayment of all outstanding principal, accrued and unpaid interest, fees, costs and expenses, equal to approximately $55.1 million in the aggregate (the "Payoff Amount"), under the Loan and Security Agreement, entered into and effective as of April 1, 2022, by and among the Company, certain of its subsidiaries from time to time party thereto, Hercules Capital, Inc. ("Hercules") and certain other lenders named therein, which was subsequently amended on August 7, 2023 and October 17, 2025 (as amended, the "Loan Agreement"). Upon receipt by Hercules of the Payoff Amount on May 27, 2026, 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 $300 million (the "Term Loan"). Under the Loan Agreement, the Company borrowed $50 million. The Term Loan bore interest at a floating per annum rate equal to the greater of 8.95% and 1.45% above the Prime Rate (as defined in the Loan Agreement), provided that the interest rate did not exceed a per annum rate of 9.45%. Interest-only payments on the borrowings under the Loan Agreement were due through October 1, 2029, or if certain regulatory milestones were met, through October 1, 2030. After the interest-only payment period, borrowings under the Loan Agreement were due in equal monthly payments of principal and accrued interest until the maturity date of October 1, 2030.
