Stock issuable upon such exercise). If at any time the beneficial ownership of the Funds and their affiliates is reduced to 4.99%
or less of the shares of Common Stock outstanding immediately after giving effect to such exercise, then the number of shares of
Common Stock that may be acquired by the Funds and their affiliates upon any exercise of the Warrants will be limited to the extent

in such notice.&nbsp; Pursuant to the Warrant to Purchase Common Stock, any such increase will not be effective until the 61st
