Forward-looking statements include, among other things, the information concerning our possible future results of operations, business and growth strategies, financing plans, expectations that regulatory developments or other matters will or will not have a material adverse effect on our business or financial condition, our competitive position and the effects of competition, the projected growth of the industry in which we operate, and the benefits and synergies to be obtained from our completed and any future acquisitions, and statements of our goals and objectives, and other similar expressions concerning matters that are not historical facts. Forward-looking statements usually, but not always, contain the words “estimate,” “anticipate,” “believe,” “expect,” or similar expressions, or the negative of those words and expressions, as well as statements in future tense, and are subject to numerous known and unknown risks and uncertainties that are beyond our ability to control or estimate precisely. In evaluating such statements, prospective investors should carefully review various risks and uncertainties identified in this report, including the matters set forth under the captions “Risk Factors” and in the registrant’s other SEC filings. These risks and uncertainties could cause the registrant’s actual results to differ materially from those indicated in, or implied by, the forward-looking statements. The registrant undertakes no obligation to update or publicly announce revisions to any forward-looking statements to reflect future events or developments, except as may be required by law.

Although forward-looking statements in this report reflect the good faith judgment of our management, such statements can only be based on facts and factors currently known by us.

Factors that could cause or contribute to such differences in results and outcomes include, without limitation, those specifically addressed under the heading “Risks Relating to Our Business” below, as well as those discussed elsewhere in this report.
