The Reporting Persons intend to review their investments in the Company on a continuing basis. Depending on various factors, including but not limited to the Company's financial position and strategic direction, price levels of the Common Stock, conditions in the securities markets, compliance with applicable listing standards, various laws and regulations applicable to the Company and companies in its industry and the Reporting Persons' ownership in the Company and position as lender to the Company, and general economic and industry conditions, the Reporting Persons may in the future take actions with respect to their investment in the Company as they deem appropriate, including changing their current intentions, with respect to any or all matters required to be disclosed in this Statement. Without limiting the foregoing, the Reporting Persons may, from time to time, acquire or cause affiliates to acquire additional shares of Common Stock or other securities of the Company (including any combination or derivative thereof), dispose, or cause affiliates to dispose, of some or all of their Common Stock or other securities of the Company or continue to hold, or cause affiliates to hold, Common Stock or other securities of the Company.

On April 23, 2024, the Funds purchased the entire outstanding principal amount of the indebtedness outstanding under the MSLP Loan Agreement (the "MSLP Loan") from the City National Bank of Florida. On May 3, 2024, the Reporting Persons delivered a nonbinding transaction proposal (the "Proposal") to the Company concerning a proposed restructuring of the Company's current debt and equity capital structure. Pursuant to the Proposal, the Reporting Persons would exchange a portion of the MSLP Loan and/or other debt instruments held by the Reporting Persons for Common Stock, in addition to entering into a new senior secured credit facility as a part of a comprehensive restructuring of the Company's outstanding debt. As a result of the transactions contemplated by the Proposal, the Reporting Persons and their affiliates would become the majority owners of the Company's common stock on a fully diluted basis. The Proposal was unilateral and non-binding and, once structured and agreed upon, would be conditioned on, among other things, the negotiation and execution of definitive documentation setting forth the terms of a transaction between the Company and the Reporting Persons, as well as the Company successfully completing an equity financing and obtaining requisite stockholder consents. There can be no assurance that a definitive agreement with respect to the Proposal will be executed or, if executed, whether the transaction will be consummated. The Reporting Persons may, directly or indirectly, take such additional steps as they may deem appropriate to further the Proposal. The foregoing does not purport to be complete and is qualified in its entirety by reference to the full text of the Proposal filed as an exhibit hereto and incorporated by reference herein. The Company and the Reporting Persons have engaged and intend to continue to engage in discussions relating to the implementation of the transactions contemplated by the Proposal and alternatives to such transactions. While the Reporting Persons have engaged in discussions with the Company to agree the terms of the transactions contemplated by the Proposal and alternatives to such transactions, there is no certainty as to the outcome of such discussions, or as to the timing for execution of any definitive agreement. As of the date hereof, no agreement has been reached nor has any definitive documentation been entered into by the Company and the Reporting Persons with respect to the transactions contemplated by the Proposal or alternatives to such transactions. On May 24, 2024, September 26, 2024, March 31, 2025, June 30, 2025 and September 30, 2025, the Company and the Reporting Persons entered into the May 2024 Exchange Agreement, September 2024 Exchange Agreement, March 2025 Exchange Agreement, June 2025 Exchange Agreement and September 2025 Exchange Agreement, respectively, pursuant to which the Funds exchanged a portion of the MSLP Loan, the 2023 Convertible Notes, the March 2025 Convertible Notes or the June 2025 Convertible Notes, as applicable, for Series Y Preferred Stock. On June 25, 2025, the Company's shareholders approved the issuance of the shares of Common Stock underlying the June 2025 Convertible Notes, Series X Preferred Stock and Series Y Preferred Stock which had previously been subject to limitations on convertibility imposed by the rules and regulations of the Nasdaq Capital Market. On January 13, 2026, Madryn discussed with the Company's board of directors its desire for the Company to reduce operational costs, including the potential delisting and deregistration of the Company's Common Stock. On March 13, 2026, Madryn and HealthQuest Partners II, L.P. (together with certain of its affiliates, "HealthQuest") reached an agreement with respect to Madryn's purchase of all of the shares of common stock and preferred stock of the Company held by HealthQuest, as documented in that certain Non-Binding Summary of Terms (the "Healthquest Term Sheet"), dated as of March 17, 2026, between Madryn and Healthquest. Pursuant to the HealthQuest Term Sheet, Madryn would acquire all shares of Common Stock and preferred stock (consisting of the Company's Voting Convertible Preferred Stock) of the Company held by HealthQuest in exchange for an aggregate purchase price of $755,646.90, payable in the form of one or more promissory notes (the "HealthQuest Notes") issued by Madryn to HealthQuest. The HealthQuest Notes would accrue interest at a rate of 4% per annum, to be paid-in-kind and compounded annually, with the balance of the HealthQuest Notes payable by Madryn on the date that is three years following the closing date of the transaction. The foregoing does not purport to be complete and is qualified in its entirety by reference to the full text of the HealthQuest Term Sheet filed as an exhibit hereto and incorporated by reference herein. On March 16, 2026, Madryn and EW Healthcare Partners, L.P. (together with certain of its affiliates, "EW") reached an agreement with respect to Madryn's purchase of (i) all of the shares of preferred stock of the Company held by EW and (ii) all of the convertible debt of the Company held by EW, as documented in that certain Non-Binding Summary of Terms (the "EW Term Sheet"), dated as of March 17, 2026, between Madryn and EW. Pursuant to the EW Term Sheet, Madryn would acquire (i) all shares of the Company's Voting Convertible Preferred Stock held by EW, (ii) all shares of the Company's Senior Convertible Preferred Stock held by EW, and (iii) those certain Secured Subordinated Convertible Notes originally issued by the Company to EW on January 18, 2024, for an aggregate purchase price of $2,600,000 (the "EW Purchase Price"). The EW Purchase Price would be payable by Madryn to EW in four cash installments of $650,000, with each installment payable 18, 24, 30 and 36 months after the closing date of the transaction, respectively. The foregoing does not purport to be complete and is qualified in its entirety by reference to the full text of the EW Term Sheet filed as an exhibit hereto and incorporated by reference herein. On March 17, 2026, in response to the Company's request to the Reporting Persons for $1.0 million of additional funding (the "Additional Funding") to be provided on or about March 24, 2026, the Reporting Persons, after discussions with the Company, delivered a nonbinding transaction proposal (the "March 2026 Proposal") to the Company. Pursuant to the March 2026 Proposal, the Company would issue shares of Common Stock to the Reporting Persons at a price per share of $0.01 (the "Price Per Share") in exchange for the Additional Funding. On a post-transaction basis, the Reporting Persons would own greater than 90% of the issued and outstanding shares of Common Stock. Pursuant to the March 2026 Proposal, the Reporting Persons would covenant to use their reasonable best efforts to effect on or before March 31, 2026 a short-form merger pursuant to Section 253 of the General Corporation Law of the State of Delaware (the "Short-form Merger"), contingent on the Reporting Persons acquisition of all of the issued and outstanding shares of the Company's preferred stock not currently owned by the Reporting Persons pursuant to the transactions contemplated by each of the HealthQuest Term Sheet and the EW Term Sheet. In connection with the Short-form Merger, each share of Common Stock would be converted into the right to receive a cash amount equal to the Price Per Share. The Price Per Share reflects the little to no value of the expected distribution to the holders of Common Stock upon a liquidation of the Company's assets after taking into consideration the repayment of the Company's debt and other obligations and the liquidation preference associated with the currently outstanding shares of the Company's preferred stock. After effecting the Short-form Merger, the Reporting Persons would own 100% of the Common Stock. The foregoing does not purport to be complete and is qualified in its entirety by reference to the full text of the March 2026 Proposal filed as an exhibit hereto and incorporated by reference herein.
