11. Commitments and Contingencies

Royalty and License Fee Commitments

The Company has entered into certain license agreements, as identified in Note 9, with third parties that include the payment of certain development and regulatory milestones, as well as royalty payments, upon the achievement of pre-established development, regulatory and commercial targets. The Company’s payment obligation related to these license agreements is contingent upon the successful development of the licensed products. Due to the nature of these arrangements, the future potential payments are inherently uncertain, and accordingly no amounts have been recorded in the Company’s accompanying Consolidated Balance Sheets at June 30, 2012 and December 31, 2011.
