PTC and HP plan to offer support for Linux users

Needham, Mass., June 10 /PRNewswire/ -- Today, in a first for the product design industry, PTC (NASDAQ: PMTC) , the product
development company(TM), announced its intention to support the Linux operating system for Pro/ENGINEER(R).
Pro/ENGINEER, PTC's flagship mechanical computer aided design (MCAD) application, gives users the power to create advanced,
high- quality product models and designs that result in superior products. A new, easy-to-use, Web-connected version of
Pro/ENGINEER, called Pro/ENGINEER Wildfire was also announced today at the PTC/USER conference (see related press release
at http://www.ptc.com/company/news/press/releases/20020610wildfire.htm). With the release of a Linux supported Pro/ENGINEER,
PTC plans to accommodate the growing demand from top design engineers to support the Linux open-source operating system.
PTC also announced its intention to align with the Hewlett-Packard Company as the Linux partner for PTC's Pro/ENGINEER.
              Working with HP, PTC intends to support two popular Linux distributions, including Red Hat, on the full range of 32-bit Intel-based
              architecture workstations available from HP with the release of Pro/ENGINEER Wildfire later this year.

              "Two of our biggest strengths with Pro/ENGINEER Wildfire are openness and value," said Brian Shepherd, senior vice president of
              technical marketing at PTC. "Adding Linux to the long list of certified platforms for Pro/ENGINEER ensures that our customers can
              take advantage of the innovations and competition taking place in the platform market to achieve the lowest total cost of ownership
              for their product development environment."

              Supporters of Linux point to a lower total cost of ownership because they can leverage their UNIX expertise on a free and open
              operating system running on cost-effective Intel architecture workstations. According to market analyst firm IDC; Linux and other
              open-source operating systems are expected to experience a 67 percent compound annual growth rate between 2001 and 2005.
              IDC Analyst Gisela Wilson states, "PTC's support for the Linux operating environment is proof of its stated commitment to
              openness and platform independence. This announcement reinforces PTC's reputation as one of the technology leaders in the
              product lifecycle management market."

              "PTC is moving ahead of the curve by working with HP to bring the power and usability of Pro/ENGINEER Wildfire to Linux," said
              Martin Fink, general manager, HP Linux Systems Division. "As the leading provider of Linux solutions, HP is ideally positioned to
              help service the growing demand for a Linux solution within product development and engineering environments."

              Thanks to an innovative software architecture, Pro/ENGINEER can accommodate a wide variety of hardware platforms and
              operating systems with full interoperability, high performance, and a fully consistent and familiar user interface. PTC has always
              shown a leading role in bringing innovations and improvements in operating systems and platforms to the engineering community.
              By partnering on this initiative with HP, the leading Linux solution provider, PTC will be able to expedite the process of bringing this
              product to market.

              "We have been long time users of Pro/ENGINEER on a variety of platforms," said Dr. Sepehr Kiani, principal engineer at Teradyne
              Connection Systems, " Pro/ENGINEER Wildfire on Linux is exciting as it will allow us to take advantage of expertise we already have
              in UNIX while allowing our top designers to run on whatever system they prefer. We really appreciate the flexibility that PTC's open
              approach gives us in designing winning products for high-speed, high-density system interconnect."
