Business Wire, Sept 13, 2005

NEEDHAM, Mass. -- PTC (Nasdaq: PMTC), the Product Development Company(TM), today announced that Exostar, the secure collaborative business network, has renewed its commitment to PTC solutions and has expanded its deployment of Windchill ProjectLink to 5,000 licenses. The strategic partnership between PTC and Exostar includes both companies coordinating efforts in R&D, marketing, education services, consulting services and sales. Together, PTC and Exostar have helped set the standard for product development collaboration in the aerospace and defense industry. E[acute accent]Exostar initially selected PTC Windchill in 2001 to power its online collaboration network. Now, almost 350 companies have adopted Exostar's ForumPass solution, fueled by PTC Windchill ProjectLink, and more than 4,000 users per month - comprising OEMs and their suppliers - are working together in a real-time, shared collaboration environment. Just recently, BAE Systems, The Boeing Company, and Rolls-Royce increased their subscription commitments to ForumPass. Diverse programs including the 787 Dreamliner as well as military submarine and fighter aircraft projects, are benefiting from the collaboration capabilities offered by Windchill-based ForumPass from Exostar. E[acute accent]"ForumPass, powered by Windchill, is the ideal collaboration solution for aerospace and defense companies who require a highly secure solution that is also flexible enough to support process improvements and operate across company and geographic boundaries," said Bill Angeloni, chief executive officer, Exostar. "We have seen a number of customers report significant benefits such as reduced time-to-market, improved operational efficiency, reduced intellectual property risk and lower development cost. PTC has been a trusted partner in making the Exostar vision a reality and we look forward to expanding the partnership and further enhancing the benefits achieved by ForumPass customers." E[acute accent]The globalization of product development and expansion of collaborative supply networks require the highest degree of security in processing the sensitive product information characteristic of aerospace and defense programs. PTC Windchill ProjectLink offers the comprehensive set of collaboration capabilities combined with an Internet-based architecture and the ability to operate in a hosted environment. With Windchill ProjectLink as its product lifecycle management (PLM) backbone, Exostar's ForumPass successfully addresses the following challenges:
