COLLABORATION AGREEMENT

5.     COLLABORATION AGREEMENT

• In October 2008, Valeant closed the License and Collaboration Agreement (the "Collaboration Agreement") to develop ezogabine/retigabine in collaboration with GSK. Pursuant to the terms of the Collaboration Agreement, Valeant granted co-development rights and worldwide commercialization rights to GSK. In consideration, the Company will receive future cash flows from worldwide sales of ezogabine/retigabine products. In March 2011, the European Commission granted marketing authorization for Trobalt™ (retigabine) as an adjunctive treatment of partial onset seizures, with or without secondary generalization in adults aged 18 years and above with epilepsy. In June 2011, the U.S. Food and Drug Administration ("FDA") approved the New Drug Application ("NDA") for Potiga™ (ezogabine) tablets as adjunctive treatment of partial-onset seizures in patients aged 18 years and older; however, the FDA recommended that ezogabine be scheduled as a controlled substance under the Controlled Substances Act prior to the marketing or launch of Potiga™. As of September 30, 2011, final classification was still under review by the U.S. Drug Enforcement Administration and Potiga™ will not be available for sale until this process is complete.

  In connection with the first sale of Trobalt™ by GSK in the European Union (which occurred in May 2011), GSK paid the Company a $40.0 million milestone payment and will pay up to a 20% royalty on net sales of the product. Upon the first sale of Potiga™ in the U.S., GSK will pay the Company a $45.0 million milestone payment, and the Company will share up to 50% of the net profits from the sale of Potiga™. As substantive uncertainty existed at the inception of the Collaboration Agreement as to whether the milestones would be achieved because of the uncertainty involved with obtaining regulatory approval, no amounts were previously recognized for these potential milestone payments. The milestone payments (1) relate solely to past performance of the Company, (2) are reasonable relative to the other deliverables and payment terms within the Collaboration Agreement, and (3) are commensurate with the Company's efforts in collaboration with GSK to achieve the milestone events and the increase in value of ezogabine/retigabine. Accordingly, the milestones are considered substantive, and the milestone payments are being recognized by the Company as alliance and royalty revenue upon achievement. In the second quarter of 2011, the Company recorded the $40 million milestone payment from GSK in connection with the launch of Trobalt™.

  The Company's rights to ezogabine/retigabine are subject to an asset purchase agreement between Meda Pharma GmbH & Co. KG ("Meda Pharma") and Xcel Pharmaceuticals, Inc., which was acquired by Valeant in 2005 (the "Meda Pharma Agreement"). Under the Meda Pharma Agreement, the Company is required to make certain milestone and royalty payments to Meda Pharma. Within the U.S., Canada, Australia and New Zealand, any royalty payments to Meda Pharma will be shared by the Company and GSK. In the rest of the world, the Company will be responsible for the payment of these royalties to Meda Pharma from the royalty payments it receives from GSK. In connection with the approval of the NDA for Potiga™, the Company made a $6.0 million milestone payment to Meda Pharma in June 2011. As this potential milestone payment had been included in the estimated net future cash flows used to determine the fair value of the ezogabine/retigabine IPR&D assets as of the Merger Date, the payment of this milestone to Meda Pharma was recorded as an addition to the value of those assets. Amortization of the ezogabine/retigabine IPR&D assets will commence with the scheduling of ezogabine as a controlled substance.
