Comment for Type of Reporting Person:
The amount reflected under "Sole Dispositive Power" consists of 1,502,080 shares of the Issuer's Common Stock, $0.01 par value per share (the "Common Stock") that are issuable upon conversion of the Issuer's Series D Convertible Preferred Stock, $0.01 par value per share (the "Series D Preferred Stock"), but does not include 4,885,920 shares of Common Stock issuable upon conversion of the Series D Preferred Stock that are convertible within 60 days because the conversion of such shares of Series D Preferred Stock are subject to a 19.99% beneficial ownership limitation. Further, the percentage reflected under "Percent of Class Represented by Amount in Row (11)" assumes that the Purchasers have not exercised the Series D Preferred Stock they acquired in the October 2025 Transactions (each as defined herein). Following such conversion, the Reporting Person's ownership percentage will be approximately 5%.
