COLLABORATION AGREEMENT

5.             COLLABORATION AGREEMENT

In October 2008, Valeant closed the worldwide License and Collaboration Agreement (the “Collaboration Agreement”) with GSK to develop and commercialize a first-in-class neuronal potassium channel opener for treatment of adult epilepsy patients with refractory partial onset seizures and its backup compounds, with a generic name of ezogabine in the U.S. and retigabine in all other countries. Pursuant to the terms of the Collaboration Agreement, Valeant granted co-development rights and worldwide commercialization rights to GSK.

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 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™. In December 2011, ezogabine/retigabine received scheduling as a controlled substance, which triggered the commencement of amortization.

In connection with the first sale of Potiga™ in the U.S. (which occurred in April 2012), GSK paid 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™. In addition, 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. 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 2012 and 2011, the Company recorded $45.0 million and $40.0 million of milestone payments from GSK in connection with the launches of Potiga™ and Trobalt®, respectively.
