                    Performance Technologies Updates Guidance
                           for the Second Quarter 2005

ROCHESTER, NY - June 30, 2005 -- Performance Technologies, Inc. (Nasdaq NM:
PTIX) today updated its guidance for the second quarter 2005. Performance
Technologies' current expectations for the second quarter include the following:

    o Earnings for the second quarter, excluding restructuring charges of
      approximately $.1 million, are now expected to be in the range of $.00 to
      $.02 per diluted share, compared to earlier guidance of $.05 to $.09 per
      diluted share.
    o Revenue for the second quarter 2005 is now expected to be between
      $10.7 million and $11.0 million, compared to earlier expectations of
      $13.0 million to $14.0 million. The reduction in revenue is due to a
      combination of customer reschedules for expected second quarter orders
      until after the second quarter, compounded by a general weakness in demand
      from several of the Company's telecommunications customers.

"General weakness and near-term deployment schedule changes in the
telecommunications market have significantly influenced the current quarter's
revenue and operating earnings," said Donald Turrell, president and chief
executive officer. "While forward-looking visibility for customer orders remains
limited, we expect deployment of major domestic network upgrades announced
earlier in the year to still move forward, thus strengthening demand for the
Company's products. In addition, the Company has cash, cash equivalents and
investments amounting to approximately $29.0 million, or $2.25 per share at June
30, 2005, and no long-term debt."

Operating expenses for the second quarter are lower than in the first quarter,
as expected, and the final step in the previously announced centralization and
streamlining plan to reduce operating expenses by approximately $2.0 million is
on schedule and will be completed in September 2005. The primary focus of this
effort is to eliminate redundancy in the Company's multi-location operations.

Further information about the Company's cost reduction efforts and second half
revenue prospects will be discussed in the Company's second quarter earnings
press release scheduled after the market closes on July 28, 2005.
