Forward-Looking Statements

This release, and other written and oral statements made by Best Buy and/or Clearwire from time to time, contains forward-looking statements which are based on management's current expectations and beliefs, as well as on a number of assumptions concerning future events made with information that is currently available. Forward-looking statements may include, without limitation, management's expectations regarding future financial and operating performance and financial condition; proposed transactions; network development and market launch plans; strategic plans and objectives; industry conditions; the strength of the balance sheet; liquidity and financing needs;business prospects; new strategies; the competitive environment and other events. The words "anticipate," "believe,""intend," "plan," "outlook," "will," "would," "may," "should," "estimate," "project," "forecast," "intend," "expect," "believe," "target," "designed," "plan" and similar expressions are intended to identify forward-looking statements. Readers are cautioned not to put undue reliance on such forward- looking statements, which are not a guarantee of performance and are subject to a number of uncertainties and other factors, many of which are outside of either company's control, which could cause actual results to differ materially and adversely from such statements.

In the case of Clearwire, some factors that could cause actual results to differ are:

• Clearwire is an early-stage company with a history of operating losses and it expects to continue to realize significant net losses for the foreseeable future.
• Clearwire's current and future plans are subject to a number of conditions and uncertainties, including among others, its ability to manage ongoing market development activities (including the development of over 10,000 sites), its performance in launched markets and its access to additional funding.
• Clearwire regularly evaluate Its plans, and the company may elect to pursue new or alternative strategies which it believes would be beneficial to the company's business, including among other things, modifying the pace at which the company builds its 4G mobile broadband networks, augmenting its network coverage in markets it launches, changing its sales and marketing strategy and or acquiring additional spectrum.
• If Clearwire's business fails to perform as the company expects, or if the company elects to pursue new plans or strategies, Clearwire may be required to raise substantial additional financing, and if it is unable to raise such financing on acceptable terms it may need to modify its plans accordingly.
• Clearwire may fail to realize all of the anticipated benefits of the transactions with Sprint and the strategic investors.
• Clearwire is committed to using commercially reasonable efforts to deploy wireless broadband networks based solely on mobile WiMAX technology, even if there are alternative technologies available in the future that are technologically superior or more cost effective.
• Clearwire currently depends on its commercial partners to develop and deliver the equipment for its legacy and mobile WiMAX networks.
• Many of Clearwire's competitors are better established and have significantly greater resources, and may subsidize their competitive offerings with other products and services.
• Clearwire's substantial indebtedness and restrictive debt covenants could limit its financing options and liquidity position and may limit the company's ability to grow its business.
• Sprint Nextel Corporation owns a majority of Clearwire's shares, resulting in Sprint holding a majority voting interest in the company, and Sprint may have, or may develop in the future, interests that may diverge from other stockholders.
• Future sales of large blocks of Clearwire's common stock may adversely impact its stock price.

Clearwire assumes no obligation to update or supplement such forward-looking statements.

In the case of Best Buy, among the factors that could cause actual results and outcomes to differ materially from those contained in such forward-looking statements are the following: general economic conditions, changes in consumer preferences, credit market constraints, acquisitions and development of new businesses, divestitures, product availability, sales volumes, pricing actions and promotional activities of competitors, profit margins, weather, changes in law or regulations, foreign currency fluctuation, availability of suitable real estate locations, the company's ability to react to a disaster recovery situation, the impact of labor markets and new product introductions on overall profitability, failure to achieve anticipated benefits of announced transactions and integration challenges relating to new ventures.
