                  PTC Reports Fiscal 2004 First Quarter Results

      - Company Achieves Operating Profit, Excluding Restructuring Charges;
                       Net Loss Narrows 30% Sequentially -

NEEDHAM, Mass., January 21, 2004 - PTC (Nasdaq: PMTC), the product development
company(TM), today reported revenue totaling $156.8 million for the first
quarter ended January 3, 2004, compared with $172.0 million for the same period
last year. Revenue declined 4% sequentially, from $163.7 million in the fourth
quarter of fiscal 2003.

Net loss for the first quarter was $26.5 million, or $0.10 per share, compared
to a net loss of $11.4 million, or $0.04 per share, for the year-ago period. On
a sequential basis, net loss declined 30% from $38.0 million, or $0.14 per
share, in the fourth quarter of 2003. Operating loss was $21.1 million in the
first quarter of 2004, compared to $9.7 million in the year-ago period, and
$31.9 million in the fourth quarter of 2003. The first quarter net and operating
losses include restructuring charges of $21.6 million, while there were no
restructuring charges in the year-ago period, and there were $15.8 million of
restructuring charges in the fourth quarter of 2003. Cash and investments were
$190.1 million at the end of the first quarter.

"This quarter, we removed more than $20 million from our expense structure, and
reached an important milestone in our plan to return to profitability by
achieving an operating profit, excluding restructuring charges," said C. Richard
Harrison, president and chief executive officer. "We accomplished this earlier
than expected through strong execution of the cost reduction program we
announced in 2003. With about 80 percent of this reduction program complete, we
have gained significant operating leverage in our business."

Total design solutions revenue for the first quarter was $113.9 million, which
was down 4% from the fourth quarter. Design solutions license revenue was $29.8
million, compared with $33.8 million in the fourth quarter. Although there was a
decline in revenue from product upgrades and new high-end seats, PTC's low-end
seat sales continued to grow, as a result of improved channel performance.
Additionally, PTC's existing customers continue to show strong adoption of
Pro/ENGINEER Wildfire; an estimated 37% of Pro/ENGINEER customers have migrated
to the new version.

Total Windchill revenue in the first quarter was $42.9 million, which was down
6% from the fourth quarter. Windchill license revenue was $13.7 million,
compared with $16.1 million in the prior quarter. Windchill Link solutions
license revenue represented 36% of overall Windchill license revenue, due in
part to lower revenue from upgrades to the Flex 3C package that includes both
Pro/ENGINEER Wildfire and Windchill Link solutions.

"During the quarter, we won several important, competitive deals that underscore
PTC's leadership position in the PLM space," continued Harrison. "By
transforming our product and service offerings into an integral product
development system that is easier to use and implement, we have significantly
improved our ability to help customers create value through product development
initiatives."

In the first quarter, PTC received orders from leading manufacturing
organizations such as Airbus Industrie, Boeing, Bosch, Boston Scientific, Deere
& Co., Hino Motors, Itochu Techno-Science Corporation, Nypro Inc., the U.S.
Army, and Volkswagen. Additionally, orders from our reseller channel resulted in
$13.4 million in license revenue during the quarter, a 45% sequential increase.

Second Quarter 2004 Financial Outlook
PTC's revenue forecast for the second quarter of fiscal 2004 is between $150
million and $160 million. As a result of the continued execution of PTC's cost
reduction plan, the Company expects to incur a restructuring charge of
approximately $15 million in the second quarter. Net loss per share is expected
to be between $0.05 and $0.09.
