Our primary company facilities are located in St. Louis, Missouri where we lease approximately 65,000 square feet of office and 12,000 square feet of demonstration and assembly space. In the third quarter of 2013, the Company modified the existing lease agreement to terminate approximately 13,000 square feet of unimproved space. The costs associated with the termination were accrued as a rent liability. The remaining contractual obligation on the St. Louis facility is $9,380,545.
