 Portions of this presentation contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include information concerning our possible or assumed future results of operations, as well as trends and conditions in our markets and technologies, market opportunity, and our plans regarding our business strategies. These statements can generally be identified by such words as "expects," "plans," "believes," "anticipates," "should," "may," "will" and similar words or expressions. Forward-looking statements are not guarantees of performance but rather reflect our current expectations, assumptions and beliefs based upon information currently available to us. Investors are cautioned that all forward-looking statements are subject to risks and uncertainties which are difficult to predict and that could cause actual results to differ materially from those projected. Many of these risks and uncertainties are described in Part I of our Form 10-K for the fiscal year ended October 31, 2009 under the heading "Risk Factors", and in our subsequently filed quarterly reports. Some of these risk factors include: the condition of the U.S. economy and its impact on capital spending trends in the Company's markets; the successful closing of pending acquisition(s); the integration of acquired businesses into that of the Company and realization of anticipated synergies and growth opportunities from such transactions; the financial condition of our suppliers and changes by them in their distribution strategies and support; changes in Avaya’s strategies regarding the provision of equipment and services to its customers, and in its policies regarding the availability of tier IV hardware and software support; the Nortel Networks bankruptcy filing and the impact that such action continues to have on the market and the Company’s products and services offering; unpredictable quarter to quarter revenues; our ability to maintain and improve upon current gross profit margins; continuing acceptance and success of the Mitel product and services offering; availability of credit to finance growth; our ability to acquire and retain the technical competencies needed to implement new advanced communications technologies; intense competition and industry consolidation; dependence upon a few large wholesale customers in our Managed Services offering; and the availability and retention of revenue professionals and certified technicians. Investors are cautioned that the foregoing list of important risk factors is not exclusive. These and other factors should be considered carefully and investors should not place undue reliance on our forward-looking statements. Forward-looking statements speak only as of the date made and we do not undertake to update any forward-looking statement that is contained in any communications. GAAP Reconciliation The Company uses Adjusted-EBITDA (earnings before net interest, income taxes, depreciation and amortization) , which excludes certain one-time and non-cash charges, as part of its overall assessment and comparison of financial performance between accounting periods. XETA believes that EBITDA is often used by the financial community as a method of measuring the Company's performance and of evaluating the market value of companies considered to be in similar businesses. EBITDA is a non-GAAP financial measure and should not be considered an alternative to net income or cash provided by operating activities, as defined by accounting principles generally accepted in the United States ("GAAP"). A reconciliation of EBITDA to net income is provided in Exhibit A. Forward-Looking Statements
