"Reporting Persons").
Item 2. Identity and Background.
Item 2 of the Schedule 13Ds are hereby amended to add the following:

The name, address, principal occupation or employment and citizenship
of each of the executive officers and directors of Sigma-Tau, Sigma Tau
International and Defiante are set forth in Schedule A hereto. Neither the
Reporting Persons nor any of the persons listed on Schedule A has been, during

warrants for the purchase of 759,493 shares of Common Stock for an aggregate

interest in the Issuer.
None of the Reporting Parties has any present plans or proposals

in clauses (a) through (j) of Item 4 of Schedule 13D.
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. Cavazza, (ii) the 1,756,782
shares of Common Stock directly owned by Mr. P. Cavazza, (iii) the 8,643,397
shares of Common Stock directly owned by Sigma Tau International, (iv) the
2,025,315 shares of Common Stock deemed to be directly beneficially owned by
Defiante, and (v) the 449,100 shares of Common Stock deemed to be directly
beneficially owned by Aptafin. This represents beneficial ownership of an
aggregate of 14,631,375 shares of Common Stock. References to beneficial
ownership are made herein solely with respect to U.S. securities laws and are
not intended to refer or apply in any respect to any other issue under any
other U.S. law.
(a) Percentage interest calculations for the Reporting Persons are
based upon Questcor having 44,379,058 shares of Common Stock outstanding as of
November 6, 2003 (the "Outstanding Shares"), as reported by the Issuer in the
Issuer's Form 10-Q for the quarterly period ended September 30, 2003 filed
with the SEC on November 12, 2003, which does not include 10,624,731 shares of
Common Stock issuable upon the conversion of Questcor's Series B Preferred
Stock (the "Preferred Stock"). The percentage interest calculation for the
Voting Shares (as defined below) includes the present voting power of
10,624,731 shares of Common Stock issuable upon the conversion of the
Preferred Stock. 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").
Accordingly, the total number of voting shares, based on the sum of the
Outstanding Shares and the Converted Shares, is 53,675,698 (the "Voting
Shares").
