COMMITMENTS AND CONTINGENCIES
From time to time we are subject to claims of various amounts, which arise out of the normal course of business. In the opinion of management, the disposition of pending claims will not have a material adverse effect on our financial position, results of operations or cash flows.

The future minimum lease payments required under these leases are approximately $0.3 million for the remainder of 2012, $1.1 million in 2013, $1.1 million in 2014, $1.0 million in 2015, $0.9 million in 2016 and $0.8 million in 2017.
