Significant Agreements
(8) SIGNIFICANT AGREEMENTS	(8) SIGNIFICANT AGREEMENTS *Merial Limited* In September 2009, we entered into a world-wide license and development agreement with Merial Limited (Merial), a leading animal health company, for a long-acting pain management product for cats and dogs. Under the terms of the agreement, we received a nonrefundable upfront license fee and performed reimbursable development services. In May 2011, we received notice of termination from Merial due to their concerns about the commercial potential of the product under development in the animal health market. We recognized no revenue related to development services provided to Merial in both the three months ended September 30, 2012 and 2011, and $0.0 and $0.5 million of revenue for the nine months ended September 30, 2012 and 2011, respectively. The remaining balance of deferred revenue related to the upfront license fee of $0.1 million was recognized as revenue in the quarter ended June 30, 2011, upon termination of the licensing agreement by Merial.
