Fair Value Measurements</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Generally accepted accounting principles define and establish a framework for measuring fair value and providing disclosure about fair value measurements. Furthermore, U.S. GAAP specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs) or reflect our own assumptions of market participant valuation (unobservable inputs). We have categorized our financial assets and liabilities, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy. If the inputs used to measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument. </div> <div align="left" style="font-size: 10pt;
