ROCHESTER, N.Y. - June 24, 2003 - Performance Technologies (Nasdaq NM: PTIX), a leader in unified systems design for the communications, military and commercial markets, today announced that Stratus Technologies, Inc. is using several of the company's IPnexus® products in its Intel processor-based, fault-tolerant server platforms.

The Stratus server solutions provide continuous uptime and protection of key data for applications such as banking, securities and exchanges, and retail transactions. Stratus is using Performance Technologies' packet-based IPnexus products and architecture to facilitate the transmission and communication of transaction data for these business-critical applications.

"Stratus servers eliminate the complexities associated with cluster deployments, while also delivering significantly better uptime performance," said Jon Malinsky, business line manager, Continuum products, Stratus Technologies.

As a result, we are able to offer the most simple, ultra-reliable server solutions in the industry."

"Stratus' reputation is based on delivering high availability transaction servers," said Ed Bizari, director of marketing for Performance Technologies. "Our IPnexus products are based on open-architecture standards. For Stratus, that meant reduced design complexity and time-to-market and an increase in overall system reliability and performance. As a leading developer of such standards-based products, we look forward to a continuing relationship with Stratus Technologies."

Stratus is using products from Performance Technologies' PICMG® 2.16-compatible IPnexus product family.
