PTC Announces Management Promotion

Board of Directors Promotes C. Richard Harrison to President & CEO;
Walske Continues as Chairman & Chief Business Strategist

WALTHAM, Mass., March 1, 2000 -- In a move designed to accelerate the company's recent Internet-based collaborative product commerce (CPC) initiatives, PTC (NASDAQ: PMTC) today announced that C. Richard Harrison has been named president and CEO. Steven C. Walske will remain as PTC's chairman and assume the newly created position of chief business strategist.

"Over the last 18 months, Dick and I have led PTC in a dramatic transformation of our company from a one-product, MCAD-only (mechanical computer-aided design) business to a multi-product company that is strategically positioned for Internet-based collaborative product commerce," said Walske. "This is a period of unprecedented opportunity for PTC to become the central player in B2B collaboration. To do so will require a stepped-up pace of new market initiatives and strategic partnerships, and I will be focusing full time on these growth issues. "

He added, "It gives me great pleasure to announce that Dick Harrison is being promoted to CEO. Dick has been critical to the transformation of the company during this period and he has effectively assumed many of the day-to-day responsibilities of CEO. This announcement of this long overdue and richly deserved promotion merely formalizes what has already been transitioned internally."

Walske concluded, "For me, this is the best of both worlds -- I can dedicate my time more fully to leveraging and extending the company's strategic business opportunities, while also collaborating with the core team helping Dick run the company. "
