Each capitalized term used and not defined herein shall have the meaning assigned to such term in the Schedule 13D. Except as otherwise provided herein, each Item of the Schedule 13D remains unchanged. Item 4 is hereby amended to add the following: On August 25, 2025, the Issuer issued separate unsecured subordinated promissory notes (collectively, the "Subordinated Notes") payable to each of Stone House Capital Management, LLC, Face Canyon LLC and Mark Tkach (collectively, the "Subordinated Lenders") to evidence $3,333,334 of unsecured subordinated loans made by each Subordinated Lender to the Issuer. The aggregate gross proceeds of the unsecured subordinated loans evidenced by the Subordinated Notes, or approximately $10.0 million, were used to prepay outstanding principal amounts of the loans (the "Senior Loans") owed under the Company's term loan credit agreement (the "Senior Credit Agreement"), among the Issuer, as borrower, the guarantors party thereto, the lenders party thereto and Oaktree Fund Administration, LLC, as administrative agent and collateral agent (the "Senior Agent"). The Subordinated Notes are subordinated in right of payment to the Issuer's obligations under the Senior Credit Agreement pursuant to the terms of a subordination agreement entered into by and among the Company, the Subordinated Lenders, and the Senior Agent. The Subordinated Notes bear interest at a rate of 13.0% per annum, payable semi-annually in arrears on the last business day of each February and August, beginning February 27, 2026. Interest is payable in-kind and capitalized to the principal balance. Each Subordinated Note matures on August 31, 2028, unless earlier repaid or accelerated in accordance with its terms. In the event a Subordinated Lender participates in a Specified Equity Offering (as defined in the Subordinated Notes), the Issuer is required to use the net cash proceeds received from such Subordinated Lender in such Specified Equity Offering to make a mandatory prepayment of such Subordinated Lender's Subordinated Note. Each Subordinated Note is guaranteed on a joint and several basis by the Issuer's subsidiaries that are guarantors under the Senior Credit Agreement (each, a "Subordinated Guaranty"). Subject to the terms of the corresponding Subordinated Note, each Subordinated Guaranty is irrevocable and unconditional, and will remain in effect until all obligations under such Subordinated Note are satisfied. The foregoing description of the Subordinated Notes and Subordinated Guaranties does not purport to be complete and is qualified in its entirety by reference to the full text of the Subordinated Notes, a form of which is attached hereto as Exhibit 99.28.
