These forward-looking statements reflect Beacon Power Corporation's current views about future events and financial performances. These forward-looking statements are identified by the use of terms and phrases such as "believe," "expect," "plan," "anticipate," and similar expressions identifying forward-looking statements. Investors should not rely on forward-looking statements because they are subject to a variety of risks, uncertainties, and other factors that could cause actual results to differ materially from Beacon Power Corporation's expectation. These factors include: a short operating history; a history of losses and anticipated continued losses from operations; a need to raise additional capital combined with a questionable ability to do so; conditions in target markets; no experience manufacturing any product or supplying frequency regulation services on a commercial basis; limited commercial contracts for sales to date; the dependence of sales on the achievement of product development and commercialization milestones, including design modifications that may be needed following a recent malfunction that occurred while testing a prototype flywheel; the uncertainty of the political and economic climate, and the different electrical grid characteristics and requirements of any foreign countries into which Beacon hopes to sell or operate, including the uncertainty of enforcing contracts, the different market structures, and the potential substantial fluctuation in currency exchange rates in those countries; significant technological challenges to successfully complete product development; dependence on third-party suppliers; intense competition from companies with greater financial resources, especially from companies that are already in the frequency regulation market; possible government regulation that would impede the ability to market products or services or affect market size; the complexity and other challenges of arranging project finance and resources for one or more frequency regulation power plants; possible product liability claims and the negative publicity which could result; any failure to protect intellectual property; retaining key executives and the possible need in the future to hire and retain key executives; the recent volatility in the stock price of companies operating in the same sector. These factors are elaborated upon and other factors may be disclosed from time to time in Beacon Power Corporation's filings with the Securities and Exchange Commission.
