Each of the Warrants and the Debentures contain provisions (the “Ownership Limitations”) limiting the percent of the outstanding Common Stock that YA Global may own. The Ownership Limitations may be waived by YA Global on 65 days notice to the Issuer. On December 30, 2008, YA Global waived the Ownership Limitation (the “Ownership Waiver”) and the Issuer waived the notice provisions (the “Notice Waiver” and together with the Ownership Waiver, the “Waiver”).
