Safe Harbor Statements under the Private Securities Litigation Reform Act of 1995: Material contained in this press release may include statements that are not historical facts and are considered "forward-looking" within the meaning of the Private Securities Litigation Reform Act of 1995. 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 history of losses and anticipated continued losses from operations; a need to raise additional capital in order to continue as a going concern, combined with a questionable ability to do so; the future issuance of debt or equity securities to obtain financing, which may adversely affect our stockholders; the complexity and other challenges of arranging project finance and resources for one or more frequency regulation power plants; limited experience manufacturing any product and no experience supplying frequency regulation services on a commercial basis; the dependence of sales on the achievement of product development and commercialization milestones; the uncertainty of the political and economic climate, and the different electrical grid characteristics and requirements of any foreign countries into which we hope to sell or operate, including the uncertain ability to enforce contracts, the different market structures, and the potential substantial fluctuation in currency exchange rates in those countries; significant technological challenges to successfully completing product development; dependence on third-party suppliers and volatility in the price and availability of carbon fiber and other materials necessary to manufacture our flywheel systems; 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; any failure to protect our intellectual property; our ability to retain or attract key executive officers and technical personnel; the recent volatility in the stock prices of companies operating in our sector; the effect of fluctuations in energy prices on the pricing of frequency regulation services; the possibility that our anti-takeover defenses could delay or prevent an acquisition and could adversely affect the price of our stock; the impact of new sources of energy on the demand for frequency regulation services; and the potentially dilutive effect on our stock price of the exercise of outstanding options and warrants. 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. Beacon Power Corporation expressly does not undertake any duty to update forward-looking statements.
