BEIJING, China, June 21, 2005 - PTC (Nasdaq:PMTC), the Product Development Company?, jointly announced today with Wuchang Shipyard the implementation of PTC’s Shipbuilding Solution comprising Windchill PDMLink?, Windchill ProjectLink? and CADDS? 5i, which will be used as a production design management platform in Wuchang Shipyard. Wuchang Shipyard is now using the solution in production, making the shipyard one of the most technologically advanced companies in China’s highly competitive shipbuilding industry.

Wuchang Shipyard, founded in 1934, is a subsidiary of the China Shipbuilding Industrial Corporation. It is one of China’s largest and most modernized shipyards with capabilities to design, build, and repair various types of ships for civil, military and tourism use, and which are used in China and exported to other countries. Wuchang Shipyard has had almost a decade of working relationship with PTC.

The completion of the PTC Shipbuilding Solution implementation is expected to bring about revolutionary changes in Wuchang Shipyard’s business processes, particularly in the way product data is managed. The shipyard uses Windchill ProjectLink as a collaborative tool for the R&D, manufacturing and production departments, thereby enabling concurrent engineering, shortening product design lead-time and accelerating time-to-market. Windchill PDMLink consolidates what used to be scattered islands of information, controlling the typically chaotic product change management processes, thus increasing productivity and preventing costly design errors. The broad functional application set of CADDS 5i is used for ship design and 3-D modeling, enabling the users’ ability to reference each others’ evolving designs and facilitating concurrent engineering. The PTC Shipbuilding Solution allows project managers to better control and resolve problems earlier in the development cycle.

“The completion of the Windchill and CADDS 5i implementation now makes Wuchang Shipyard one of the most technologically advanced enterprises in our industry. We are very proud to have PTC as our partner, and we are confident that the implementation will bring about revolutionary and positive changes in our business processes,” said Wuchang Shipyard Chief Executive Officer, Lv Dachang.

In line with its business expansion plans, Wuchang Shipyard intends to increase usage of Windchill and CADDS5i throughout its organization in the future.

“We are very pleased to have successfully completed the implementation of our Shipbuilding Solution for Wuchang Shipyard,” said PTC Chief Executive Officer, C. Richard Harrison. “This marks a significant milestone for both Wuchang Shipyard and PTC as we continually expand our relationship. We are confident that Wuchang Shipyard’s business will benefit from improved collaboration and product data management.”
