                PTC Provides Third Quarter 2003 Financial Update

NEEDHAM, Mass., July 2, 2003 - PTC (Nasdaq: PMTC) today announced that it
expects revenue for the fiscal 2003 third quarter ended June 28, 2003 to be
approximately $165 million, compared with the Company's guidance of
approximately $170 million. GAAP net loss per share for the third quarter is
expected to be in the range of $0.12 to $0.14. This includes restructuring
charges of approximately $8 million associated with PTC's previously announced
cost reduction plan, as well as a charge of approximately $6 million to increase
previously established liabilities for excess leased facilities associated with
PTC's 1998 acquisition of Computervision Corporation.

"Our net loss for the quarter will be higher than expected, due primarily to the
facilities charge made necessary by the weakened commercial real estate market
in the Northeast U.S.," said Neil Moses, executive vice president and chief
financial officer. "We are aggressively implementing the operating cost
reductions announced in April. These actions should result in a modest benefit
to operating expenses in the third quarter, with a more pronounced benefit in
the fourth quarter as we position ourselves for profitability in 2004."

"Revenue growth continues to be challenging as the manufacturing sector has
remained stagnant," added C. Richard Harrison, president and chief executive
officer. "Nevertheless, our commitment to our strategy has significantly
improved our ability to help customers drive value within product development
more quickly and cost-effectively. This has clearly strengthened the confidence
our customers have in PTC and our competitive position in the marketplace."

PTC expects to announce final results for the third quarter on Wednesday, July
16, before the market opens. On that day at 10 a.m. ET, the Company will hold a
conference call and live webcast to discuss its results and provide an outlook
update (the earnings press release and accompanying financial and operating
