These premises serve as our corporate headquarters. The initial term of the lease expires on October 31, 2012 and the lease provides one renewal option for an additional three-year term. Facility rent expense for this facility totaled approximately $11,300 and $10,700 for the three months ended March 31, 2012 and 2011, respectively. Future minimum rental payments for the remainder of the initial lease term totals approximately $26,300. Rutgers License In February 2007, we acquired an exclusive, royalty-bearing license in specific but broad global territories to make, have made, use, sell, offer for sale, modify, develop, import, and export products made using patent applications owned by Rutgers University (Rutgers ). We are using these patented technologies in the production of our composite rail ties and structural building products. The term of the License Agreement runs until the expiration of the last-to-expire issued patent within the Rutgers  technologies licensed under the License Agreement, unless terminated earlier. We are obligated to pay Rutgers royalties ranging from 1.5% to 3.0% on various product sales, subject to certain minimum payments each year and to reimburse Rutgers for certain patent defense costs in the case of patent infringement claims made against the Rutgers patents. We also pay annual membership dues to Rutgers Center for Advanced Materials via Immiscible Polymer Processing, or AIMPP, a department of Rutgers. The membership allows us to use AIMPP for basic research and development at no additional cost, with access to more comprehensive R&amp;D services available to us for fees determined on a per-project basis. Litigation In April 2006, we commenced an action against Tonga Partner
