a combination of continued organic growth and the addition of revenue from Arbortext, which PTC acquired in July 2005. PTC license revenue grew 25% during the quarter reflecting stronger-than-expected software sales in both large customer accounts
and the small and medium business market. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">&#147;We are off to a great start to
2006,&#148; said C. Richard Harrison, president and chief executive officer. &#147;Our results reflect strong performance across product lines, with particularly outstanding performance in Windchill and our channel. These results clearly demonstrate
traction in two of our most important strategic initiatives and largest growth opportunities. Our Windchill 8.0 launch last June has already resulted in increased sales of Windchill PDMLink and Pro/INTRALINK. And the small and medium business market
is accelerating its adoption of our Pro/ENGINEER solutions.&#148; </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">GAAP net
income for the first quarter was $7.5 million, or $0.03 per diluted share, compared with GAAP net income of $19.2 million, or $0.07 per diluted share, in the year-ago period. PTC adopted FAS 123(R) in the fourth quarter of fiscal year 2005, and
therefore the GAAP results from the year-ago period do not include the cost of stock-based compensation in accordance with FAS 123(R). Non-GAAP net income, which excludes stock-based compensation cost, amortization of acquisition-related intangible
assets, in-process research and development write-offs associated with acquisitions, restructuring charges, if any, and the related tax effect of these items, as well the effect of one-time tax items, if any, was $18.8 million for the first quarter,
or $0.07 per diluted share, compared to $19.5 million in the year-ago period, or $0.07 per diluted share. We have provided a reconciliation between GAAP and non-GAAP results in the attached financial tables. </FONT></P> <P

Solutions license revenue was $22.4 million, up 55% from the year-ago period. This exceptional growth reflects significantly accelerated revenue growth from our Windchill PDMLink and Pro/INTRALINK products, as well as additional revenue from

any. GAAP requires that these costs and charges be included in costs and expenses and accordingly used to determine operating income (loss) and earnings per share. The Company&#146;s management uses non-GAAP operating costs, and associated non-GAAP
net income (which is the basis for non-GAAP earnings per share) to make operational and investment decisions, and the Company believes that they are among several useful measures for an enhanced understanding of our operating results for a number of

Second, although the Company undertakes analyses to ensure that its stock-based compensation grants are in line with peer companies and do not unduly dilute shareholders, the Company allocates these grants and measures them at the corporate level.
Management excludes their financial statement effect when planning or measuring the periodic financial performance of the Company&#146;s functional organizations since the grants are episodic in nature and unrelated to our core operating metrics.
Likewise, we believe that excluding items such as in-process R&amp;D write-offs and amortization of intangible assets associated with acquisitions, or restructuring charges that are not directly attributable to our ongoing operations and that do not
generally fluctuate in correlation with periodic performance, provides investors with information that helps to compare period-over-period operating performance by highlighting the effect of the acquisitions or restructuring activities on our
results of operations. In addition, the Company&#146;s management excludes the financial statement effect of these items in creating operating budgets for the Company&#146;s functional business units and in evaluating and compensating employees due
to the fact that it is difficult to forecast these expenses. Lastly, we believe that providing non-GAAP earnings per share affords investors a view of earnings that may be more easily compared to peer companies and enables investors to consider the
Company&#146;s earnings on both a GAAP and non-GAAP basis in periods when the Company is engaged in acquisition activities or undertaking non-recurring activities. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT

higher degree of transparency for certain expenses, and providing a level of disclosure that will help investors understand how the Company plans and measures its own business. However, non-GAAP net income (loss) should be construed neither as an
alternative to GAAP net income (loss) or earnings (loss) per share as an indicator of our operating performance nor as a substitute for cash flow from operations as a measure of liquidity because the items excluded from the non-GAAP measures often
have a material impact on the Company&#146;s results of operations. Therefore, management uses, and investors should use, non-GAAP measures in conjunction with our reported GAAP results. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT
