  Pursuant to the terms of certain warrants and convertible notes (collectively, the “Securities”), the RTW Funds cannot exercise or convert such Securities if the Reporting Persons would beneficially own, after such exercise or conversion, more than 9.99% of the outstanding Shares (the "9.99% Blocker").  The percentage set forth on Row (11) and the number of shares of Common Stock set forth on rows (6), (8) and (9) of the cover page for each Reporting Person give effect to the 9.99% Blocker. Consequently, at this time, the Reporting Persons are not able to convert all the Securities held by the RTW Funds due to the 9.99% Blocker.
