Item 5. Interest in Securities of Questcor. ----------------------------------- Item 5 of the Schedule 13Ds are hereby amended as follows: The Reporting Persons, because they may be considered a "group" for purposes of Section 13(d)(3) of the Act (the "Group"), may be deemed solely for purposes of U.S. securities laws to beneficially own (i) the 1,756,781 shares of Common Stock directly owned by Mr. C.

Each share of Preferred Stock is entitled to a number of votes equal to 0.875 times the number of shares of Common Stock issuable upon conversion of such shares of Preferred Stock, resulting in the voting equivalence of 9,296,640 shares of Common Stock (the "Converted Shares").
