(A)

Our revolving credit facility, as amended (the “Working Capital Revolver Loan”), provides for advances up to $65 million (the “Maximum Revolver Amount”), based on specific percentages of eligible accounts receivable and inventories and up to $10 million of letters of credit, the outstanding amount as of March 31, 2023, was $0.9 million, which reduces the amount available for borrowing under the Working Capital Revolver Loan. At March 31, 2023, our available borrowings under our Working Capital Revolver Loan were approximately $62.3 million, based on our eligible collateral, less outstanding letters of credit and loan balance. The maturity date of the Working Capital Revolver Loan is on the earlier of (i) the date that is 90 days prior to the earliest stated maturity date of the Senior Secured Notes (unless refinanced or repaid) and (ii) February 26, 2024. Subject to certain conditions and subject to lender approval, the Maximum Revolver Amount may increase up to an additional $10 million. The Working Capital Revolver Loan also provides for a springing financial covenant (the “Financial Covenant”), which requires that, if the borrowing availability is less than 10.0% of the total revolver commitments, then the borrowers must maintain a minimum fixed charge coverage ratio of not less than 1.00 to 1.00. The Financial Covenant, if triggered, is tested monthly.
