The Company’s obligation to fund these efforts is contingent upon continued involvement in the programs and/or the lack of any adverse events which could cause the discontinuance of the programs. 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 September 30, 2010 or December 31, 2009. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt"><b>Contingencies: </b>The Company believes it maintains insurance coverage adequate for its current needs.
