**Comment for Reporting Person:** As more fully described in Item 5, the shares of Preferred Stock and Warrants are subject to a 9.99% blocker, and the percentage set forth in row (13) gives effect to such blockers. The securities reported in rows (8), (10) and (11) show the number of shares of Common Stock that would be issuable upon full conversion and exercise of such reported securities and do not give effect to such blockers. Therefore, the actual number of shares of Common Stock beneficially owned by such Reporting Person, after giving effect to such blockers, is less than the number of securities reported in rows (8), (10) and (11).
