Cautionary Statement

    The Private Securities Litigation Reform Act of 1995 (the "Act")
provides a "safe harbor" for forward-looking statements. Certain
statements contained in this press release such as statements
concerning planned projects, statements regarding sales pipeline,
backlog and revenue projections, statements containing the words
"expects," "estimates," "anticipates," "believes," "projects" and
variations thereof, and other statements contained in this press
release regarding matters that are not historical facts are forward
looking statements as such term is defined in the Act. Because such
statements involve risks and uncertainties, actual results may differ
materially from those expressed or implied by such forward-looking
statements. Factors that could cause actual results to differ
materially include, but are not limited to, uncertainties involving
development stage companies, uncertainties regarding project
financing, the lack of binding commitments and the need to negotiate
and execute definitive agreements for the construction and financing
of projects, financing and cash flow requirements and uncertainties,
difficulties involved in developing and executing on a business plan,
difficulties and uncertainties regarding acquisitions, technological
uncertainties, risks relating to managing and integrating acquired
businesses, unpredictable developments (including plant outages and
repair requirements), the difficulty of estimating construction,
development, repair and maintenance costs and timeframes, the
uncertainties involved in estimating insurance and implied warranty
recoveries, if any, the inability to predict the course or outcome of
any negotiations with parties involved with Environmental Power's or
Microgy's projects, uncertainties relating to general economic and
industry conditions, the amount and rate of growth in expenses,
uncertainties relating to government and regulatory policies, the
legal environment, intellectual property issues, the competitive
environment in which Environmental Power and Microgy operate and other
factors, including those described in the Company's most Annual Report
on Form 10-K and most recent Quarterly Report on Form 10-Q, as well as
other filings with the Securities and Exchange Commission. Readers are
cautioned not to place undue reliance on these forward-looking
statements, which speak only as of the date that they are made.
Environmental Power undertakes no obligation to publicly update or
revise any forward-looking statements, whether as a result of new
information, future events or otherwise.
