The Company also paid a certain final payment due relative to such prior term loan. The Third Amendment sets the maturity date for the Third Amendment Term Loan to September 1, 2029 (the “Third Amendment Term Loan Maturity Date”), and defers the first principal repayment due date relative to the Third Amendment Term Loan to October 1, 2027; provided that upon the achievement of the Performance Milestone (as defined in the Third Amendment), the first principal payment shall become due on October 1, 2028. Interest on the Third Amendment Term Loan will be payable monthly at a floating rate per annum equal to the greater of 4.25% and the prime rate minus 0.5%. The Company may elect to prepay the Third Amendment Term Loan in whole prior to the Third Amendment Term Loan Maturity Date, subject to a prepayment fee equal to 1.5% of the original principal amount of the Third Amendment Term Loan if it is prepaid within 18 months following the closing of the Third Amendment. The Third Amendment further revised certain provisions related to financial covenants and the periods in which the covenants apply, and First-Citizens and the Company also terminated the revolving credit facility in an aggregate principal amount of up to $15.0 million and an uncommitted accordion term loan provision.
