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 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 on a commercial basis; the company has only
recently entered into the renewable energy market through its inverter products,
and hence, has only limited  experience in this sector;  the dependence of sales
on the achievement of product development and commercialization  milestones; the
uncertainty of the political and economic climate of any foreign  countries into
which Beacon hopes to sell, including the uncertainty of enforcing contracts 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;  possible government regulation that
would impede the ability to market products;  possible product  liability claims
and  the  negative   publicity  which  could  result;  any  failure  to  protect
intellectual  property;  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;  the power of controlling  shareholders and the limited ability
of others to influence  the outcome of matters put to the vote of  shareholders.
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
