Legal Proceedings

We are currently involved in a variety of legal matters that arise in the normal course of business. Based on information currently available, management does not believe that the ultimate resolution of these matters will have a material adverse effect on our financial condition, results of operations and cash flows. Were an unfavorable ruling to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs.

However, borrowing under this subfacility is limited to the extent of availability under the $15.0 million revolving line of credit that was due and payable on October 31, 2011.
