                     Performance Technologies Updates Guidance
                             for the Third Quarter 2004



ROCHESTER, NY - October 6, 2004 -- Performance Technologies, Inc. (Nasdaq NM:
PTIX) today updated its guidance for the third quarter 2004.  Performance
Technologies' current expectations for the third quarter include the following:

   o Revenue for the third quarter 2004 is expected to be between $11.0 million
     and $11.5 million, compared to earlier guidance of $13.5 million to $14.5
     million. The reduction in revenue is due to a combination of customers 
     rescheduling third quarter orders until after the third quarter, customer 
     orders being received too late to allow fabrication for third quarter
     shipment and the general weakness of orders from the Company's 
     telecommunications customers.

   o In September, the Company sold its minority interest in Momentum Computer,
     Inc. for $2.1 million and realized a gain of approximately $1.2 million, or
     $.09 per diluted share. The total amount of cash consideration amounted to
     $3.1 million, including the payoff of a note receivable from Momentum.

   o GAAP earnings for the third quarter, including the gain on the Momentum
     investment, is now expected to be in the range of $.09 to $.11 per diluted
     share, compared to earlier guidance of $.06 to $.09 per diluted share.

"Weakness in sectors of the telecommunications market has placed significant
pressure on the current quarter's revenue and operating earnings," said Don 
Turrell, president and chief executive officer. "Despite the current weakness,
we continue to believe the Company's products are strategically positioned to
increase market share and to improve the Company's financial performance when
the fundamentals of its markets become more positive. Nonetheless, management is
formulating actions and taking steps to reduce annualized expenses by
approximately $2.0 million. The primary focus of this effort is to eliminate
redundancy in the Company's multi-location operation and to streamline the
organization."

The first step in this effort began in September and targets the integration of
the recently acquired Voice Technology Group's sales and administrative
functions with the corporate sales and administrative organizations. This action
is expected to be completed in October. Further information about these cost
reduction efforts will be discussed in the Company's third quarter earnings
press release scheduled after the market closes on October 27, 2004.
