Forward Looking StatementsThis presentation includes “forward-looking statements” within the meaning of the securities laws. The statements in this presentation regarding plans for the development and deployment of a broadband network based on WiMAX technology; the timing, availability, capabilities, coverage, and costs of the WiMAX network; planned market launches; products and services to be offered by Clearwire; and other statements that are not historical facts are forward-looking statements. The words “will,” “would,” “may,” “should,” "estimate," "project," ”forecast,” "intend," "expect," "believe," "target," “designed” and similar expressions are intended to identify forward-looking statements. Forward-looking statements are projections reflecting management's judgment and assumptions based on currently available information and involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements.

Future performance cannot be assured. Actual results may differ materially from those in the forward-looking statements due to a variety of factors, including, but not limited to: the costs and business risks associated with deploying a WiMAX network and offering products and services utilizing WiMAX technology; our ability to raise additional substantial financing in both the near term and long term, which in turn could require us to substantially modify our business plan; our substantial indebtedness, which could affect our ability to raise additional capital; the inability of third-party suppliers, software developers and other vendors to perform requirements and satisfy obligations necessary to create products and software designed to support WiMAX features and functionality; the impact of adverse network performance; worsening economic conditions; and other risks referenced from time to time in Clearwire’s filings with the Securities and Exchange Commission, including in the Annual Report on Form 10-K, in the section titled “Risk Factors.” Clearwire believes the forward-looking statements in this presentation are reasonable; however, you should not place undue reliance on forward-looking statements, which are based on current expectations and speak only as of the date of this presentation. Clearwire is not obligated to publicly release any revisions to forward-looking statements to reflect events after the date of this presentation. A reconciliation of pro forma financial information and any non-GAAP financial measures discussed in this presentation can be found in the Investor Relations section of our website.
