Forward-looking statements are subject to significant risks, uncertainties and changes in circumstances and actual outcomes and results may differ materially from those in the forward-looking statements as a result of various factors, including but not limited to the risk factors disclosed in our reports with the SEC, many of which are beyond our control. You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Any forward-looking statement made by us is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise. 2
