Item 1.01 Entry into a Material Definitive Agreement.

On January 2, 2013, Questcor Pharmaceuticals, Inc. ("Questcor") and its wholly owned subsidiary ("Acquisition Co."), entered into a Share Purchase Agreement (the "Agreement") to acquire all of the issued and outstanding shares of BioVectra Inc. ("BioVectra"). Upon closing of the transaction contemplated by the Agreement, BioVectra will become a wholly owned subsidiary of Acquisition Co. The purchase price consists of approximately C$50.0 million in cash at the closing plus up to an additional C$50.0 million in cash tied to the future performance of BioVectra. The consummation of the transaction contemplated by the Agreement is subject to customary closing conditions.

The parties to the Agreement have made customary representations and warranties, which will generally survive for a period of 24 months following the closing of the transaction. In addition, the parties to the Agreement are subject to customary pre-closing covenants pursuant to the Agreement. The covenants require, among other things, that BioVectra's business be generally conducted in the ordinary course in all material respects during the interim period between the execution of the Agreement and the closing of the transaction. The parties to the Agreement have rights to indemnification for, among other things, breaches of representations and warranties, subject to customary limitations, and for non-performance of their respective covenants.
