Amendment No. 2 waives certain defaults or events of default under the Existing Credit Agreement, including in connection with the Company’s Net Leverage Ratio and Fixed Charge Coverage Ratio covenants for the second fiscal quarter. Amendment No. 2 also amends the Existing Credit Agreement to, amongst other things, (i) reduce the interest rate margins applicable to Term Loans (as described in further detail below), (ii) provide for the right to appoint an independent director to the Company’s board of directors following the earlier to occur of (x) an event of default or (y) any date selected by the Administrative Agent after May 31, 2025, (iii) permit the incurrence of $40.0 million of senior unsecured subordinated debt (as described in further detail below), (iv) suspend the fixed charge coverage ratio and the net leverage ratio covenants in the Amended Credit Agreement such that the next test will be for the quarter ending on October 31, 2025 (v) reduce the minimum quarterly average liquidity requirement from $20.0 million to $17.5 million and (vi) suspend the Company’s ability to pay interest in-kind until after the interest rate margins are tested based on Net Leverage Ratios. The Amended Credit Agreement provides that the interest rate margins on the Term Loans are reduced from 13.00% to 10.50% per annum for SOFR Loans until the first business day of the month following October 31, 2025, when the Company has delivered financial statements demonstrating compliance with the financial covenants under the Amended Credit Agreement. If demonstrated, the interest rate margins revert to the margins provided under the Existing Credit Agreement with respect to Term Loans, specifically, (i) Base Rate Loans shall bear interest at the Base Rate plus an additional margin ranging from 7.50% to 9.00% and (ii) SOFR Loans shall bear interest at the Term SOFR rate plus an additional margin ranging from 8.50% to 10.00%, each depending on the Company’s Net Leverage Ratio during the applicable determination period ranging from 1.75x to 3.25x, respectively. Amended Subordinated Credit Agreement On March 3, 2025, the Company entered into the Waiver and Amendment No. 1 to Subordinated Credit Agreement (“Amendment No. 1”) with the guarantors party thereto, the lenders party thereto and U.S. Bank Trust Company, National Association, as agent (the “Subordinated Agent”), which amends that certain Subordinated Credit Agreement, dated October 17, 2024, among the Company, the guarantors party thereto, the lenders party thereto and the Subordinated Agent (the “Existing Subordinated Credit Agreement” and, as amended by Amendment No. 1, the “Amended Subordinated Credit Agreement”; the Amended Subordinated Credit Agreement, together with the Amended Credit Agreement, the “Credit Agreements”). Amendment No. 1 (x) waives defaults or events of default under the Existing Subordinated Credit Agreement, including in connection with the Company’s Net Leverage Ratio and Fixed Charge Coverage Ratio covenants for the second quarter of fiscal 2025 and (y) amends the Existing Subordinated Credit Agreement to, amongst other things, (i) provide for the incurrence of a $40.0 million incremental facility (as described in further detail below) and (ii) suspend the fixed charge coverage ratio and the net leverage ratio covenants in the Credit Agreements such that the next test will be for the quarter ending on October 31, 2025. Amendment No. 1 provides for an incremental subordinated unsecured term loan facility in the aggregate principal amount of $40.0 million (the “Incremental Subordinated Credit Facility”). The Company will use the net proceeds of the Incremental Subordinated Credit Facility to prepay approximately (i) $27.3 million of the outstanding Term Loans under the Amended Credit Agreement and (ii) $9.1 million of the outstanding Revolving Loans under the Amended Credit Agreement. As part of this prepayment, the Company will also permanently reduce its Amended Credit Agreement Revolving Commitments by approximately $3.2 million. The Incremental Subordinated Credit Facility is subject to a Make-Whole Amount with respect to certain repayments or prepayments. The Make-Whole Amount is an amount equal to (i) from the closing date of the Incremental Subordinated Credit Facility (the “Incremental Closing Date”) through (but not including) the date that is 9 months thereafter, $40.0 million multiplied by 33.0%, (ii) from the date that is 9 months after the Incremental Closing Date through (but not including) the date that is the second anniversary of the closing date, $40.0 million multiplied by 50.0%, (iii) from the second anniversary of the Incremental Closing Date and thereafter, $40.0 million multiplied by 75.0% plus, in the case of clause (iii), interest accrued on $40.0 million at the Make-Whole Interest Rate (as defined below) starting on the second anniversary of the Incremental Closing Date and calculated as of any such date of determination. The Make-Whole Interest Rate is a rate equal to 16.0% per annum, which is increased by 2.0% per annum upon the occurrence and during the continuation of an event of default under the Amended Subordinated Credit Agreement. The Incremental Subordinated Credit Facility has the same terms and is generally subject to the same conditions applicable to the existing subordinated term loans under the Amended Subordinated Credit Agreement. The other material terms of the Amended Subordinated Credit Agreement remain unchanged. Terms used, but not defined, in this Form 8-K have the meanings set forth in the Amended Credit Agreement or the Amended Subordinated Credit Agreement, as applicable. The foregoing descriptions of the Credit Agreements are not complete and are qualified in their entirety by the actual terms of the Credit Agreements, copies of which are attached to this report as Exhibit 10.1 and Exhibit 10.2 and are incorporated herein by reference.

Upon the occurrence of such repurchases by an Investor or the Company, the Company will issue to each Investor whose shares of Series B-3 Convertible Preferred Stock were repurchased a warrant to purchase Common Stock (a “Warrant”). A Warrant will represent the right to acquire Common Stock, as further described in the Subscription and Exchange Agreement, for a term of five years and six months from the issuance of such Warrant, in the amount of (x) the aggregate Liquidation Preference of shares of Series B-3 Convertible Preferred Stock purchased by the Company divided by (y) the Conversion Price as of such Optional Repurchase Date or the Optional Call Date, subject to adjustments set forth in the Warrant, and with an initial exercise price equal to the Conversion Price as of such Optional Repurchase Date or the Optional Call Date, as applicable, in each case, subject to adjustments substantially similar to the Series B-3 Convertible Preferred Stock.
