Credit agreement, variable rate description |  |  | In its original form, the Credit Agreement featured two financial covenants: a Maximum Total Leverage Ratio, under which the Company’s borrowing capacity varies with its financial performance, measured in terms of Consolidated EBITDA as defined in the Credit Agreement, for the trailing twelve-month period; and a Fixed Charge Coverage Ratio. Under the Credit Agreement, revolving loans bear interest at a variable rate based, at borrower’s election with proper notice, on either (i) SOFR plus 0.1% per annum and the “Applicable Margin” or (ii) the greater of (x) the Prime Rate, (y) the Federal Funds Rate plus 0.5%, and (z) the Daily One-Month SOFR Rate plus 1.10%, plus, in the case of (x), (y) or (z), the Applicable Margin (“Adjusted Base Rate Revolver Loan”). Interest payments for SOFR Revolver Loans are payable on the last day of each interest period (either one-, three- or nine- months, as selected by the Company) and the maturity date, while interest payments for Adjusted Base Rate Revolver Loans are payable on the last business day of each month and the maturity date. |  |  |  |  |  |  |  |  |  |  |  |  |  |

Credit agreement, variable rate description |  |  | under the terms of the Eleventh Amendment, two new covenants were added. First, commencing June 30, 2025, Borrowers must maintain Liquidity (unused Revolver Commitment plus 100% cash held at Agent and 50% cash held at bank accounts outside the U.S.) measured on a monthly basis of not less than: $30,000 for the month ending June 30, 2025; $35,000 for the month ending July 31, 2025; $4,042 for the month ending August 31, 2025; $25,000 for the month ending September 30, 2025; $3,000 for the month ending October 31, 2025; $9,292 for the month ending November 31, 2025; and $20,000 for the month ending December 31, 2025, it being understood that liquidity will include the sum of Borrowers’ cash, plus 50% of cash held in accounts outside of the U.S. plus the amount by which the revolver commitments exceed the revolver balance (net of letters of credit). Second, Borrowers must attain minimum, year-to-date Consolidated EBITDA (reflecting the exclusion of non-recurring non-cash charges and certain other charges as per the Eighth Amendment) as measured quarterly in the following amounts: $4,500 as of June 30, 2025; $9,500 as of September 30, 2025; and $35,000 as of December 31, 2025.
