Item 2.01 Completion of Acquisition or Disposition of Assets.

On August 31, 2011, Aptalis Pharma Inc. (the “Company”), acting through its indirect parent company Aptalis Holdings Inc. (formerly known as Axcan Holdings Inc.) (“Holdings”) and direct, wholly-owned subsidiary Axcan Lone Star Inc. (“Merger Sub”), completed its acquisition of rights to Aeroquin^TM, a proprietary aerosol formulation of levofloxacin, which is currently in Phase 3 clinical trials for the treatment of pulmonary infections in patients with cystic fibrosis. The acquisition of Aeroquin^TM was completed through the merger of Mpex Pharmaceuticals, Inc. (“Mpex”) with and into Merger Sub, with Mpex being the surviving corporation and a direct, wholly-owned subsidiary of the Company (the “Surviving Corporation”).

The acquisition was completed in accordance with the terms of the previously announced transaction agreements among the Company’s affiliates and Mpex. These transaction agreements include: (a) the Agreement and Plan of Merger, dated as of April 11, 2011, as amended by the First Amendment to Option Agreement and Agreement and Plan of Merger dated as of May 26, 2011, and as further amended from time to time (the “Merger Agreement”), by and among Holdings, Merger Sub, Mpex and certain Mpex stockholders who are serving as the Mpex securityholders’ representative in connection with the acquisition (the “Securityholders’ Representative Committee”), (b) the Option Agreement, dated as of April 11, 2011, as amended by the First Amendment to Option Agreement and Agreement and Plan of Merger dated as of May 26, 2011 (the “Option Agreement”), by and among Holdings, Merger Sub and Mpex and (c) the Development Agreement, dated as of April 11, 2011, as amended from time to time (the “Development Agreement”), by and among Holdings, Merger Sub and Rempex Pharmaceuticals, Inc. (the assignee of Mpex) (“Rempex”).

The acquisition has resulted in the payment obligations summarized below, which payment obligations to date have been fulfilled by or on behalf of Merger Sub and in the future will be fulfilled by or on behalf of the Surviving Corporation.

Merger Agreement

Pursuant to the Merger Agreement, the Mpex securityholders were paid at closing approximately $8.6 million. This payment is subject to future adjustment based on final calculations of Mpex’s cash on hand, debt and transaction expenses as of closing.

Pursuant to the Merger Agreement, the Mpex securityholders will be entitled to the following payments in the future: (a) $20 million in non-contingent payments, (b) up to $195 million in contingent payments if certain regulatory and commercial milestones related to Aeroquin™ are met and (c) earn-out payments based on net sales of Aeroquin™. These payments are subject to offset against any indemnification claims that Holdings and Merger Sub have against the Mpex securityholders pursuant to the Merger Agreement, subject to the limitations set forth in the Merger Agreement.

Option Agreement

Pursuant to the related Option Agreement, which provided Holdings with an option to terminate the Merger Agreement, the Mpex securityholders and the Securityholders’ Representative Committee are entitled to an aggregate of $42.5 million in non-contingent payments ($12.0 million of which have been paid to date).

The option to terminate the Merger Agreement expired on August 12, 2011, pursuant to the Option Agreement’s terms.

Development Agreement

Pursuant to the related Development Agreement, which provides for Mpex (previously) or Rempex (currently) to have primary responsibility for conducting day-to-day development activities of Aeroquin™ and for Holdings and Merger Sub (or the Surviving Corporation) to have input regarding development strategy of Aeroquin™, Mpex (previously) or Rempex (currently) is entitled to payment for actual development costs of Aeroquin™ ($29.9 million of which have been paid to date).
