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 manure-to-energy
systems which will use our highly efficient and proven anaerobic digestion
technology, that our licensed technology will help clean up the significant
environmental problems, our beliefs as to providing a unique solution, our
projected financial performance, statements containing the words "expects,"
"estimates," "anticipates," "believes," "projects" and variations thereof, and
other statements contained herein 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, 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 Quarterly Report on Form 10-Q for the
quarter ended June 30, 2003, as well as other filings with the Securities and
Exchange Commission. Readers are cautioned not to place undue reliance on these
