Cautionary Statement

The Private Securities Litigation Reform Act of 1995 (the "Act") provides a
"safe harbor" for forward-looking statements. Certain statements made in the
exhibit to this report, such as statements concerning estimated market potential
and target markets, expectations as to Microgy's profitable production of
renewable energy, beliefs as to investment in the future which will greatly
increase shareholder value in the long-term, potential in the generation of
electricity from agricultural wastes, additional farms entering into
arrangements with us, efforts to build and finance projects, rapid expansion to
meet demands of our markets, potential for growth in markets, belief as to our
anaerobic digestion electricity product being competitive with other sources,
expectations of agricultural waste solutions being profitable to farmers and
that we can grow dramatically and profitably, beliefs as to Microgy's business
complimenting our existing business, beliefs as to our licensed technology
providing a unique solution to two critical market needs, the technology turning
an expensive agricultural industry problem into a profit-generating solution for
farmers and other statements contained herein which are not historical facts are
forward looking statements as such term is defined in the Act. Without limiting
the foregoing, the words "believes", "anticipates", "plans", "expects", "will"
and similar expressions are intended to identify forward-looking statements.
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 requirements and uncertainties, difficulties involved in
executing on a business plan, technological uncertainties, risks relating to
managing and integrating acquired businesses, volatile and 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 POWR's or Microgy Cogeneration
Systems, Inc.'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 POWR and
Microgy operate and other factors, including those described in POWR's filings
with the Securities and Exchange Commission, including the



section "Management's Discussion and Analysis of Financial Condition and Results
of Operations -- Certain Factors That May Impact Future Results" of POWR's
Annual Report on Form 10-K for the period ended December 31, 2001. Readers are
cautioned not to place undue reliance on these forward-looking statements, which
speak only as of their dates. POWR undertakes no obligation to publicly update
or revise any forward-looking statements, whether as a result of new
information, future events or otherwise.
