This Amendment No. 11 (the “Amendment No. 11”) amends the Statement on Schedule 13D filed with the Securities and Exchange Commission (“SEC”) on March 25, 2002 (the “Sigma/Defiante Schedule 13D”), as amended, relating to shares of the common stock, no par value (the “Common Stock”), of Questcor Pharmaceuticals, Inc., a California corporation (“Questcor”). This Amendment No. 13 (the “Amendment No. 13” and, together with the Amendment No. 11, this “Statement”) amends the Statement on Schedule 13D, filed with the SEC on August 7, 2001 (the “Cavazza/Sigma Schedule 13D” and, together with the Sigma/Defiante Schedule 13D, the “Schedule 13Ds”), as amended, relating to the shares of Common Stock. Pursuant to Rule 13d-2 of Regulation 13D-G promulgated under the Securities Exchange Act of 1934, as amended (the “Act”), this Amendment No. 11 is being filed on behalf of Sigma Tau Finanziaria SpA, an Italian corporation (“Sigma Tau”) and Defiante Farmaceutica L.D.A., a Portuguese corporation (“Defiante”) (formerly known as Defiante Farmaceutica Unipessoal L.D.A.), and this Amendment No. 13 is being filed on behalf of Sigma-Tau International S.A., a Luxembourg corporation (“Sigma Tau International”) (formerly known as Sigma-Tau Finance Holding S.A.), Aptafin S.p.A., an Italian corporation (“Aptafin”), Chaumiere - Consultadoria & Servicos SDC Unipessoal LDA, a Portuguese corporation (“Chaumiere”), Inverlochy Consultadoria & Servicos L.D.A., a Portuguese corporation (“Inverlochy”), Mr. Claudio Cavazza (“Mr. C.
