The following constitutes Amendment No. 4 ("Amendment No. 4") to the Schedule 13D filed by the undersigned with the Securities and Exchange Commission on January 24, 2024 (the "Original Schedule 13D"), as amended by Amendment No. 1 to the Original Schedule 13D filed by the undersigned with the Securities and Exchange Commission on June 18, 2024 ("Amendment No. 1"), Amendment No. 2 to the Original Schedule 13D filed by the undersigned with the Securities and Exchange Commission on October 18, 2024 ("Amendment No. 2") and Amendment No. 3 to the Original Schedule 13D filed by the undersigned with the Securities and Exchange Commission on March 4, 2025 ("Amendment No. 3" and the Original Schedule 13D as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3 and this Amendment No. 4, the "Schedule 13D"). This Amendment No. 4 supplements Items 4, 6 and 7 and amends and restates Item 5(a)-(c) as set forth below. Unless specified otherwise, capitalized terms used but not defined herein shall have the meanings ascribed to them in the Schedule 13D.

**Item 4. Purpose of Transaction**

Amendment No. 2 to the Subordinated Credit Agreement.

On July 21, 2025, the Issuer entered into the Amendment No. 2 to Subordinated Credit Agreement ("Amendment No. 2") with the guarantors party thereto, the lenders party thereto and the Subordinated Agent, which amends the Amended Subordinated Credit Agreement.

Amendment No. 2 amends the Amended Subordinated Credit Agreement to, among other things, (i) provide for the incurrence of a $35.0 million incremental facility (as described in further detail below), (ii) suspend, until the four-quarter period ending January 31, 2027, testing of the fixed charge coverage ratio, the net leverage ratio and the minimum EBITDA covenants in the Amended Subordinated Credit Agreement, (iii) modify the interest rate applicable to the subordinated term loans (as described in further detail below), (iv) reduce the minimum EBITDA requirement (as described in further detail below), (v) reduce the minimum quarterly average liquidity requirement from $17.5 million to $15.0 million, (vi) permit the Issuer to engage in the Specified Permitted Individual Disposition, on the terms, and subject to documentation, reasonably acceptable to the Subordinated Agent, and (vii) require the Issuer to adopt management incentive and retention arrangements for its key personnel in connection with the contemplation of the Issuer's strategic alternatives.

Amendment No. 2 provides for an incremental priority subordinated unsecured term loan facility in the aggregate principal amount of $35.0 million (the "Incremental Priority Subordinated Credit Facility"), which has been extended by lenders other than the White Hat Funds. The interest on the Incremental Priority Subordinated Credit Facility shall be paid in kind monthly in arrears, by capitalizing and adding the unpaid and accrued amount of such interest to the aggregate outstanding principal amount of the Incremental Priority Subordinated Credit Facility on the last business day of each month. The Incremental Priority Subordinated Credit Facility will rank senior in right of payment to the existing subordinated term loans under the Amended Subordinated Credit Agreement. Unlike the existing subordinated term loans, the Incremental Priority Subordinated Credit Facility is not subject to any make-whole premium.

Under the Amended Subordinated Credit Agreement, the interest rate applicable to the Incremental Priority Subordinated Credit Facility shall be the greater of (x) the highest per annum interest rate then-applicable to the Term Loans under the Existing Credit Agreement, as amended (the "Amended Credit Agreement"), and (y) Term SOFR (as defined in the Amended Credit Agreement) plus 10.5%.

Under the Amended Subordinated Credit Agreement, the required minimum EBITDA was amended and restated such that (i) for the four-quarter period ending January 31, 2027, the Issuer shall maintain a minimum EBITDA of $26,000,000, (ii) for the four-quarter period ending April 30, 2027, the Issuer shall maintain a minimum EBITDA of $28,000,000, (iii) for the four-quarter period ending July 31, 2027, the Issuer shall maintain a minimum EBITDA of $30,000,000, and (iv) for the four-quarter period ending October 31, 2027 and the four-quarter period ending on the last day of each fiscal quarter thereafter, the Issuer shall maintain a minimum EBITDA of $32,000,000.

Except as otherwise discussed above, the Incremental Priority Subordinated Credit Facility generally has the same terms and is 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.

Capitalized terms used, but not defined, in this section under the heading "Amendment No. 2 to Subordinated Credit Agreement" have the meanings set forth in the Existing Credit Agreement, the Amended Subordinated Credit Agreement or Amendment No. 2, as applicable.

The foregoing description of Amendment No. 2 does not purport to be complete and is qualified in its entirety by reference to the full text of Amendment No. 2. For further information regarding Amendment No. 2 reference is made to the text of Amendment No. 2, which has been filed as Exhibit 99.18 hereto, and incorporated by reference herein.
