Item 1.01 Entry into a Material Definitive Agreement

Adoption of Executive Incentive Performance Plan for Fiscal 2007.

On November 3, 2006, the Compensation Committee of PTC's Board of Directors
established, pursuant to the Company's Executive Incentive Performance Plan,
target incentive bonus amounts for its executive officers, including its Chief
Executive Officer, for the 2007 fiscal year performance period (the "2007 EIP").
Under the 2007 EIP, the Committee determined that each participating officer's
fiscal 2007 incentive bonus would be comprised of shares of performance-based
restricted stock, the restrictions on which will lapse based on achievement of
the specified performance metrics, and an upside bonus payable in cash based on
achievement of additional specified performance metrics.

The executive officers designated to participate in the 2007 EIP and the number
of shares of restricted stock granted to each officer under the 2007 EIP are set
forth below:



                                                                                Shares Restricted
Name                                                                               Stock Granted
------------------------------------------------------------------------        ------------------
                                                                                   
C. Richard Harrison, Chief Executive Officer & President                              37,615

Cornelius F. Moses, Executive Vice President and Chief Financial Officer              16,121

James E. Heppelmann, Executive Vice President, Software Solutions
     and Chief Technology Officer                                                     16,121

Barry F. Cohen, Executive Vice President, Strategic Services & Partners               16,121

Paul J. Cunningham, Executive Vice President, Sales                                   16,121

Anthony DiBona, Executive Vice President, Maintenance                                 12,091

Aaron C. von Staats, Senior Vice President and General Counsel                         9,404


Under the 2007 EIP, the restrictions on the shares of restricted stock will
lapse only if PTC achieves specified minimum revenue and operating margin
results (the "Threshold Performance Metrics"). If the Threshold Performance
Metrics are achieved, the restrictions on 50% of each officer's shares of
restricted stock will lapse on the later of November 9, 2007 or the date the
Compensation Committee determines the Threshold Performance Metrics have been
achieved. If the Threshold Performance Metrics are not achieved, all shares
granted under the 2007 EIP will be forfeited.

The restrictions on up to an additional 25% of an officer's shares of restricted
stock will lapse to the extent PTC achieves a second specified revenue metric
(the "Revenue Target") and the restrictions on up to the other 25% of an
officer's shares of restricted stock will lapse to the extent PTC achieves a
second specified operating margin (the "Margin Target" and together with the
Revenue Target, the "Target Performance Metrics"). In each case, the portion of
the additional 25% of the shares of restricted stock with respect to which the
restrictions will lapse increases proportionately based on PTC's achievement of
the Revenue Target or the Margin Target, as applicable, with the restrictions on
the full 25% of the respective shares of restricted stock lapsing if PTC
achieves the Revenue Target or the Margin Target, as applicable. If and to the
extent the Revenue Target and the Margin Target are achieved, the restrictions
on each officer's shares of restricted stock will lapse on the later of November
9, 2007 or the date the Compensation Committee determines the Revenue Target and
the Margin Target have been achieved.

In order to provide an additional performance incentive, if PTC exceeds the
Target Performance Metrics, each officer would become eligible for an additional
specified cash bonus (the "Upside Bonus"). The portion of the Upside Bonus
payable would increase proportionately based on PTC's achievement of additional
specified upside performance metrics (the "Upside Performance Metrics") above
the Target


                                       2


Performance Metrics. The full amount of the Upside Bonus would not be
paid unless the Upside Performance Metrics were achieved. The full amount of the
Upside Bonus for which each of the executive officers is eligible is set forth
below.
