                IMPORTANT RISK FACTORS REGARDING FUTURE RESULTS
 
  Information we provide, including information contained in this Annual
Report on Form 10-K, or by our spokespersons from time to time, may contain
forward-looking statements about projected financial performance, market and
industry segment growth, product development, and commercialization, or other
aspects of our future operations. These statements are based on the
assumptions and expectations of our management at the time such statements are
made. We caution you that our performance (and, therefore, any forward-looking
statement) is subject to risks and uncertainties. Various important factors,
including but not limited to those discussed here, may cause our future
results to differ materially from those projected in any forward-looking
statement. Important information about these factors and the basis for these
assumptions is contained in "Important Risk Factors Affecting Results"
included in "Management's Discussion and Analysis of Financial Condition and
Results of Operations" in the 1998 Annual Report to Stockholders, which
section is filed as part of Exhibit 13.1 herewith and incorporated herein by
reference.
 
                                    PART I
 
ITEM 1: BUSINESS
 
                                    GENERAL
 
  Parametric Technology Corporation (PTC), incorporated in Massachusetts in
1985, develops, markets, and supports a comprehensive suite of integrated
product development and information management software. Our mechanical design
automation product family automates product development from conceptual design
through production. Our enterprise information management solutions accelerate
the flow of product data from engineering to other critical areas of an
enterprise. Our solutions are complemented by the strength and experience of
our professional services organization, which provides training, consulting,
and support to customers worldwide.
 
                           MERGERS AND ACQUISITIONS
 
  In January 1998, we merged with Computervision Corporation, a leading
provider of product design and development software and services, by issuing
11.6 million shares of our common stock in exchange for all of the outstanding
common stock of Computervision. The merger is intended to qualify as a tax-
free reorganization and has been accounted for as a pooling of interests.
Accordingly, we have restated our consolidated financial statements to include
the accounts and operations of Computervision for all years presented in this
Annual Report on Form 10-K. Unless otherwise indicated, this discussion and
the consolidated financial statements and notes to consolidated financial
statements (Notes) reflect that restatement.
 
  The Computervision merger strengthened our customer base, particularly in
the automotive, aerospace, and shipbuilding industries, and broadened our
strategic business relationships with companies such as Airbus Industrie, BMW
Rolls-Royce, Fiat, General Electric, Lockheed Martin, Raytheon, and Rolls-
Royce Aerospace. The Computervision merger also provided an opportunity for us
to expand our data management technology and infrastructure, and added depth
and experience to our worldwide professional services organization.
 
  In June 1998, we acquired ICEM Technologies, a division of Control Data
Systems, Inc., for approximately $41 million in cash. Headquartered in
Frankfurt, Germany, ICEM provides advanced surfacing and reverse engineering
software tools used by body and styling engineers in the automotive and
aerospace industries. We accounted for the acquisition as a purchase, and we
included the operating results of ICEM in our results from the date of its
acquisition.
 
 
                                       3
<PAGE>
 
  In October 1998, we acquired all of the outstanding stock of InPart Design,
Inc. by issuing 2.4 million shares of common stock. InPart, located in
Saratoga, CA, provides a comprehensive library of standard mechanical parts
over the Internet that helps manufacturers improve product development cycles
and reduce component expenses. Because we share InPart's vision regarding the
future of Web-based enterprise applications, the acquisition provided us an
opportunity to strengthen our development and technical expertise in this
area. We will account for the acquisition as a purchase.
 
                             PRODUCTS AND SERVICES
 
  Mechanical CAD/CAM/CAE (computer-aided design, manufacturing and
engineering) software solutions encompass a broad spectrum of engineering
disciplines essential to the development of virtually all manufactured
products, ranging from consumer products to jet aircraft. Manufacturers
compete on the basis of cost, time to market, and product performance
criteria, which are significantly affected by the quality and length of the
product development process. Our mechanical CAD/CAM/CAE products, including
Pro/ENGINEER(R) and CADDS(R)5, and our functional simulation software,
Pro/MECHANICA(R), offer high-performance, fully integrated solutions which
enable end-users to reduce their time to market and manufacturing costs for
their products and to improve product quality by easily evaluating multiple
design alternatives. We believe that our mechanical design automation
solutions offer better price/performance, greater functionality, and more
complete integration of multiple engineering disciplines than other available
mechanical CAD/CAM/CAE products.
 
  The newest member of the Pro/ENGINEER family, Pro/DESKTOP(TM), is an entry
level, Windows(R)-native product development tool. Pro/DESKTOP offers an
easily accessible, innovative design system that, integrated with
Pro/ENGINEER, provides customers a completely scalable, interoperable suite of
associative design solutions that meet the needs of users throughout the
product development continuum. This cross-organization suite gives our
customers the unique ability to engage a broader range of participants in the
product development process and to extend the use of their product information
assets throughout the enterprise.
 
  Through our acquisition of ICEM Technologies, we have added a premier Class
A surface modeling product, ICEM Surf(TM), to our mechanical design automation
solutions. ICEM Surf is used in the automotive industry by nearly all major
manufacturers for modeling of high-quality, Class A surfaces as well as in the
industrial design, tool design, and consumer product markets.
 
  In June 1998, we announced that our information management products,
Pro/INTRALINK(R) and Optegra(R), would be complemented by Windchill(TM), our
new product and process management solution. Windchill uses a unique, Web-
centric approach to solving today's mission-critical product and process
management challenges. By capitalizing on the inherent benefits of the Web
manageability, usability, and low cost implementation Windchill offers
customers a significant advantage in their efforts to improve their product
differentiation and organizational effectiveness. Windchill delivers a common
infrastructure that helps companies achieve sustained competitive advantage
through more effective product life cycle management. The Windchill product
currently comprises Windchill Foundation(TM), an information framework with a
consistent architecture that includes document management, life cycle
management, workflow, and vaulting capabilities; Windchill PDM(TM), which
includes applications that address product structure, alternate views, and
change management; and Windchill Information Modeler(TM), an information
modeling and development environment.
 
  As a result of our acquisition of InPart Design, Inc., we now offer
DesignSuite(TM), an Internet-based library of three dimensional CAD parts.
DesignSuite contains two and three dimensional geometry, technical
specifications, and component selection software that allows mechanical
engineers to download more than 250,000 certified part designs via the
Internet, saving valuable time and expense.
 
  The technology solutions offered by our mechanical design and information
management products are enhanced by our professional services organization
(PSO), which is committed to providing the expertise to meet the
implementation, education, and technical support requirements of every type of
company and user--in eight
 
                                       4
<PAGE>
 
major support centers and more than 50 educational facilities worldwide. From
developing Pro/ENGINEER deployment plans, to creating customized training
courses, to implementing Web-based, enterprise-wide, product information
systems, our PSO works with customers to accelerate their migration to a more
efficient, collaborative development environment.
 
                              PRODUCT DEVELOPMENT
 
  The mechanical CAD/CAM/CAE industry is characterized by rapid technological
advances. Our ability to develop new products rapidly is facilitated by the
modular structure of our software code, which enables functional capabilities
used in existing products to be accessed and utilized by new software modules,
thereby reducing the amount of new code required to develop additional
products. The major benefit of this approach is rapid development of new
functionality. Our Windchill product line expands the breadth of our offerings
into enterprise product information and process management. This developing
industry is characterized by new technologies, including Internet-centric,
Java-based, object-oriented software. The Windchill product depends upon these
new technologies as well as certain third-party technologies.
 
  We work closely with our customers to define improvements and enhancements
to be integrated into our products. Using this approach, customers become
involved in the product design process to validate feasibility and to
influence functionality early in the product's life-cycle. In addition, our
Cooperative Software Program (CSP) provides the mechanism and environment to
facilitate the integration of complementary products with our product lines.
Through our open software toolkit, CSP members can build tightly integrated
solutions that satisfy the various requirements of our customers.
 
  Our research and development expenses were $79.6 million in fiscal 1996,
$93.3 million in fiscal 1997, and $93.4 million in fiscal 1998.
 
                              SALES AND MARKETING
 
  We derived most of our revenue from products distributed directly to our
end-user customers with the remainder offered through third-party
distributors. No single customer accounted for more than 10% of our revenue in
any of the last three fiscal years.
 
  In the fourth quarter of 1998, we initiated a worldwide reorganization of
our sales force and PSO. This initiative, which was implemented in October
1998, was designed to refocus our sales and services organizations on major
accounts, primary accounts, and Windchill accounts. As part of this
initiative, we signed a multi-year agreement with Rand A Technology
Corporation (Rand) to become the master distributor of our core products to
small businesses. This agreement gives Rand the rights to distribute certain
CAD/CAM/CAE products and their related maintenance services to the small
business segment throughout North America and Europe.
 
  In August 1998, we repackaged and repriced our core Pro/ENGINEER product
line. We now offer a base package called Pro/ENGINEER-Foundation which can be
augmented with up to 24 functionally defined extensions to accommodate a full
range of process automation and complexity requirements from an individual
user to an entire enterprise.
 
  Information about our foreign and domestic operations and export sales, and
the risks thereof, may be found in Note M and the section entitled
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" of our 1998 Annual Report to Stockholders, included in Exhibit
13.1 to this Annual Report on Form 10-K and incorporated herein by reference.
 
                                       5
<PAGE>
 
                                  COMPETITION
 
  There are an increasing number of competitive mechanical CAD/CAM/CAE
products. We compete most directly with products developed by Dassault and
marketed by Dassault and IBM, products marketed by Unigraphics Solutions, and
products developed and marketed by Structural Dynamics Research Corporation.
Our Windchill product line expands the breadth of our offerings into
enterprise product information and process management. We are a relatively new
entrant into this area and may be competing with more mature products that may
have an established customer base as well as greater functionality.
 
                              PROPRIETARY RIGHTS
 
  Our software products are proprietary to PTC. We protect our intellectual
property rights by relying on copyrights, trademarks, patents, and common law
safeguards, including trade secret protection, as well as restrictions on
disclosures and transferability contained in our agreements with other
parties. Despite these measures, there can be no assurance that the laws of
all relevant jurisdictions will afford the same protections to our products
and intellectual property as the laws of the United States. The software
industry is characterized by frequent litigation regarding copyright, patent,
and other intellectual property rights. While we have not, to date, had any
significant claims of this type asserted against us, there can be no assurance
that someone will not assert such claims against us with respect to existing
or future products or that, if asserted, we would prevail in such claims. In
the event a lawsuit of this type is filed, it could result in significant
expense to us and divert the efforts of our technical and management
personnel, whether or not we ultimately prevail.
 
  We believe that, due to the rapid pace of innovation within our industry,
factors such as the technological and creative skills of our personnel are
more important to establishing and maintaining a technology leadership
position within the industry than are the various legal protections
surrounding our technology. We believe that our products and technology do not
infringe any existing proprietary rights of others, although there can be no
assurance that third parties will not assert infringement claims in the
future.
 
  Parametric Technology Corporation, Pro/ENGINEER, Pro/MECHANICA,
Pro/INTRALINK, CADDS, and Optegra are registered trademarks of PTC or our
subsidiaries in the United States and/or other countries. Parametric
Technology, PTC, the PTC logo, and all product names in the PTC product family
are trademarks of PTC or our subsidiaries in the United States and other
countries. All other companies and products referenced herein have trademarks
or registered trademarks of their respective holders.
 
                                    BACKLOG
 
  We generally ship our products within 30 days after acceptance of a customer
purchase order and execution of a software license agreement. Accordingly, we
do not believe that our backlog at any particular point in time is indicative
of future sales levels.
 
                                   EMPLOYEES
 
  As of September 30, 1998, we had 4,911 employees, including 2,440 in sales,
marketing, and support activities; 1,078 in customer support, training, and
consulting; 435 in management, finance, and administration; and 958 in product
development. Of these employees, 2,280 were located throughout the United
States and 2,631 were located in foreign countries.
 
ITEM 2: PROPERTIES
 
  Our executive offices are located in approximately 302,000 square feet of
office space in Waltham, Massachusetts. We also lease 229 offices in the
United States and internationally through our foreign subsidiaries,
predominately as sales and/or support offices and for development work. Of our
total 2,146,000
 
                                       6
<PAGE>
 
square feet of leased facilities, 1,387,000 are located in the U.S. and
759,000 are located outside the U.S. Several of our leased facilities were
acquired in our merger with Computervision, including 696,000 square feet of
office space in Bedford, Massachusetts. Of the leased facilities acquired in
the Computervision merger, approximately 273,000 square feet are vacant. As
described in Notes B and H, certain of these facilities have been included in
our restructuring provision. We are seeking alternate uses for such facilities
including subleasing and early lease terminations. We believe that our
facilities are adequate for our present needs, but will continue to evaluate
the need for additional space as the requirements of our business change.
 
ITEM 3: LEGAL PROCEEDINGS
 
  Certain class action lawsuits were filed in the fourth quarter of fiscal
1998 against us and certain of our current and former officers and directors
in the U.S. District Court in Massachusetts claiming violations of the federal
securities laws based on alleged misrepresentations regarding our anticipated
revenue and earnings for the third quarter of fiscal 1998. These actions seek
unspecified damages. We believe the claims are without merit, and we intend to
defend them vigorously. We cannot predict the ultimate resolution of these
actions at this time, and there can be no assurance that the litigation will
not have a material adverse impact on our financial condition or results of
operations.
 
  We are also subject to various legal proceedings and claims that arise in
the ordinary course of business. We currently believe that resolving these
matters will not have a material adverse impact on our financial condition or
our results of operations.
 
ITEM 4: SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  No matters were submitted to a vote of security holders during the last
quarter of fiscal 1998.

       PARAMETRIC TECHNOLOGY CORPORATION 1997 INCENTIVE STOCK OPTION PLAN

                 Nonstatutory Stock Option Terms And Conditions


      1. Plan Incorporated by Reference. This Option is issued pursuant to the
         ------------------------------
terms of the Plan and may be amended as provided in the Plan. Capitalized terms
used and not otherwise defined in this certificate have the meanings given to
them in the Plan. This certificate does not set forth all of the terms and
conditions of the Plan, which are incorporated herein by reference. The
Committee administers the Plan and its determinations regarding the operation of
the Plan are final and binding. Copies of the Plan may be obtained upon written
request without charge from the Corporate Counsel of the Company.

      2. Option Price. The price to be paid for each share of Common Stock
         ------------
issued upon exercise of the whole or any part of this Option is the Option Price
set forth on the face of this certificate.

      3. Exercisability Schedule. This Option may be exercised at any time and
         -----------------------
from time to time for the number of shares and in accordance with the
exercisability schedule set forth on the face of this certificate, but only for
the purchase of whole shares. This Option may not be exercised as to any shares
after the Expiration Date.

      4. Method of Exercise. To exercise this Option, the Optionholder shall
         ------------------
deliver written notice of exercise to the Company specifying the number of
shares with respect to which the Option is being exercised accompanied by
payment of the Option Price for such shares in cash, by certified check or in
such other form, including shares of Common Stock of the Company valued at their
Fair Market Value on the date of delivery or a payment commitment of a financial
or brokerage institution, as the Committee may approve. Promptly following such
notice, the Company will deliver to the Optionholder a certificate representing
the number of shares with respect to which the Option is being exercised.

      5. No Right To Employment. No person shall have any claim or right to be
         ----------------------
granted an Option. Each employee of the Company or any of its Affiliates is an
employee-at-will (that is to say that either the Participant or the Company or
any Affiliate may terminate the employment relationship at any time for any
reason or no reason at all) unless, and only to the extent, provided in a
written employment agreement for a specified term executed by the chief
executive officer of the Company or his duly authorized designee or the
authorized signatory of any Affiliate. Neither the adoption, maintenance, nor
operation of the Plan nor any Option hereunder shall confer upon any employee of
the Company or of any Affiliate any right with respect to the continuance of
his/her employment by the Company or any such Affiliate nor shall they interfere
with the right of the Company (or Affiliate) to terminate any employee at any
time or otherwise change the terms of employment, including, without limitation,
the right to promote, demote or otherwise re-assign any employee from one
position to another within the Company or any Affiliate.

      6. Effect of Grant. Participant shall not earn any Options granted
         ---------------

which are required to be met in order to exercise the Option have been fully
satisfied.

      7. Recapitalization, Mergers, Etc. As provided in the Plan, in the event
         ------------------------------
of corporate transactions affecting the Company's outstanding Common Stock, the
number and kind of shares subject to this Option and the exercise price
hereunder shall be equitably adjusted. If such transaction involves a
consolidation or merger of the Company with another entity, the sale or exchange
of all or substantially all of the assets of the Company or a reorganization or
liquidation of the Company, then in lieu of the foregoing, the Committee may
upon written notice to the Optionholder provide that this Option shall terminate
on a date not less than 20 days after the date of such notice unless theretofore
exercised. In connection with such notice, the Committee may in its discretion
accelerate or waive any deferred exercise period.

      8. Option Not Transferable. This Option is not transferable by the
         -----------------------
Optionholder otherwise than by will or the laws of descent and distribution, and
is exercisable, during the Optionholder's lifetime, only by the Optionholder.
The naming of a Designated Beneficiary does not constitute a transfer.

      9. Termination of Employment or Engagement. If the Optionholder's status
         ---------------------------------------
as an employee or consultant of (a) the Company, (b) an Affiliate, or (c) a
corporation (or parent or subsidiary corporation of such corporation) issuing or
<PAGE>
 
assuming a stock option in a transaction to which section 424(a) of the Code
applies, is terminated for any reason (voluntary or involuntary) and the period
of exercisability for a particular Option following such termination has not
been specified by the Board, each such Option then held by that Participant
shall expire to the extent not previously exercised ten (10) calendar days after
such Participant's employment or engagement is terminated, except that -
                                                           ------ ---- 

        (a)    If the Participant is on military, sick leave or other bona fide
                                                                      ---- ----
leave of absence (such as temporary employment by the federal government), his
or her employment or engagement with the Company will be treated as continuing
intact if the period of such leave does not exceed ninety (90) days, or, if
longer, so long as the Participant's right to reemployment or the survival of
his or her service arrangement with the Company is guaranteed either by statute
or by contract; otherwise, the Participant's employment or engagement will be
deemed to have terminated on the 91st day of such leave.

        (b)    If the Participant's employment is terminated by reason of his
or her retirement from the Company at normal retirement age, each Option then
held by the Participant, to the extent exercisable at retirement, may be
exercised by the Participant at any time within three (3) months after such
retirement unless terminated earlier by its terms.

        (c)    If the Participant's employment or engagement is terminated by
reason of his or her death, each Option then held by the Participant, to the
extent exercisable at the date of death, may be exercised at any time within one
year after that date (unless terminated earlier by its terms) by the person(s)
to whom the Participant's option rights pass by will or by the applicable laws
of descent and distribution.

        (d)    If the Participant's employment or engagement is terminated by
reason of his or her becoming permanently and totally disabled, each Option then
held by the Participant, to the extent exercisable upon the occurrence of
permanent and total disability, may be exercised by the Participant at any time
within one (1) year after such occurrence unless terminated earlier by its
terms. For purposes hereof, an individual shall be deemed to be "permanently and
totally disabled" if he or she is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment
which can be expected to result in death or which has lasted or can be expected
to last for a continuous period of not less than twelve (12) months. Any
determination of permanent and total disability shall be made in good faith by
the Company on the basis of a report signed by a qualified physician.

           10. Compliance with Securities Laws. It shall be a condition to the
               -------------------------------
Optionholder's right to purchase shares of Common Stock hereunder that the
Company may, in its discretion, require (a) that the shares of Common Stock
reserved for issuance upon the exercise of this Option shall have been duly
listed, upon official notice of issuance, upon any national securities exchange
or automated quotation system on which the Company's Common Stock may then be
listed or quoted, (b) that either (i) a registration statement under the
Securities Act of 1933 with respect to the shares shall be in effect, or (ii) in
the opinion of counsel for the Company, the proposed purchase shall be exempt
from registration under that Act and the Optionholder shall have made such
undertakings and agreements with the Company as the Company may reasonably
require, and (c) that such other steps, if any, as counsel for the Company shall
consider necessary to comply with any law applicable to the issue of such shares
by the Company shall have been taken by the Company or the Optionholder, or
both. The certificates representing the shares purchased under this Option may
contain such legends as counsel for the Company shall consider necessary to
comply with any applicable law.

           11. Payment of Taxes. The Optionholder shall pay to the Company, or
               ----------------
make provision satisfactory to the Company for payment of, any taxes required by
law to be withheld with respect to the exercise of this Option. The Committee
may, in its discretion, require any other Federal or state taxes imposed on the
sale of the shares to be paid by the Optionholder. In the Committee's
discretion, such tax obligations may be paid in whole or in part in shares of
Common Stock, including shares retained from the exercise of this Option, valued
at their Fair Market Value on the date of delivery. The Company and its
Affiliates may, to the extent permitted by law, deduct any such tax obligations
from any payment of any kind otherwise due to the Optionholder.

 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
 OPERATIONS
- --------------------------------------------------------------------------------


PARAMETRIC TECHNOLOGY CORPORATION

Parametric Technology Corporation (PTC) develops, markets, and supports a
comprehensive suite of integrated product development and information management
software. Our mechanical design automation product family automates product
development, from conceptual design through production. Our enterprise
information management solutions accelerate the flow of product data from
engineering to other critical areas of an enterprise. Our solutions are
complemented by the strength and experience of our professional services
organization, which provides training, consulting, and support to customers
worldwide.

Unless otherwise indicated, all references to a year reflect our fiscal year
which ends on September 30.


FORWARD-LOOKING STATEMENTS

This Annual Report contains forward-looking statements that describe our
anticipated financial results and growth based on our plans and assumptions.
Important information about the basis for these plans and assumptions and
certain factors that may cause our actual results to differ materially from
these statements is contained below in "Important Risk Factors Affecting
Results."


COMPUTERVISION MERGER

In January 1998, we merged with Computervision Corporation by issuing 11.6
million shares of our common stock in exchange for all of the outstanding common
stock of Computervision. The merger is intended to qualify as a tax-free
reorganization and has been accounted for as a pooling of interests.
Accordingly, we have restated our consolidated financial statements to include
the accounts and operations of Computervision for all years presented in this
Annual Report. Unless otherwise indicated, this discussion and the accompanying
consolidated financial statements and notes to the consolidated financial
statements (Notes) reflect that restatement. In July 1997, Computervision sold a
majority interest in its other services business unit, which had generated other
services revenue and costs in 1996 and 1997. Because of the sale, the results of
this business have been excluded from the following discussion for all years
presented. See Notes B and C.


RESULTS OF OPERATIONS

The following is an overview of our results of operations:

 .    Total software revenue was $902.9 million for 1996, $979.8 million for
     1997, and $1,018.0 million for 1998.

 .    Our year-over-year software revenue growth rate declined from 33% in 1996
     to 9% in 1997 and 4% in 1998.

 .    Excluding acquisition, nonrecurring, and extraordinary charges in all years
     presented, our year-over-year net income decreased 21% in 1997 from $182.3
     million in 1996 to $144.4 million in 1997 and increased 37% to $197.6
     million in 1998.

The following table shows certain consolidated financial data as a percentage of
our total revenue for the last three years. The results of the Computervision
other services business unit have been omitted from the table.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS

REVENUE

We derived our revenue primarily from software used in the mechanical segment of
the CAD/CAM/CAE (computer-aided design, manufacturing, and engineering)
industry. Our overall rate of revenue growth declined in 1997 and 1998 from
historic levels due to a decrease in the rate of growth of license revenue.
License revenue increased 5% in 1997, reflecting continued worldwide acceptance
of our products and services, and decreased 6% in 1998, reflecting, among other
factors, a change in the mix of our product offerings, weaker than anticipated
results in the Asia/Pacific region, the strengthening of the U.S. dollar against
most major European and Asia/Pacific currencies, especially the Japanese yen,
and a reduction in the average price of our software, due in part to the
repricing and repackaging initiative for our core Pro/ENGINEER product line that
we undertook in the fourth quarter of 1998. Product unit sales remained
relatively constant during the last three fiscal years. In addition to our
repricing and repackaging initiative, in June 1998 we introduced our new
Windchill information management software and in the fourth quarter of 1998 we
announced a restructuring of our worldwide sales force and our agreement with
Rand A Technology Corporation under which, beginning in 1999, Rand will manage
all of our sales to small businesses in the United States and Europe. These
initiatives were designed to provide a foundation for future growth. The
attention devoted to their initial implementation by sales management, however,
may have had an unanticipated negative effect upon license revenue in 1998.
Since these initiatives began late in 1998 and will continue into 1999, their
impact on our results is not yet known. Consequently, we remain cautious in our
overall outlook for 1999, with flat revenue anticipated over the first half of
the year. Factors affecting our revenues and operating results are listed under
"Important Risk Factors Affecting Results" below.


         REVENUE BY TYPE (in millions) for fiscal 1996, 1997, and 1998
                            * License     @ Service

                                  [BAR CHART]


We licensed over 90% of our products directly to end-user customers in each of
the last three fiscal years. The balance was licensed through third-party
distributors. The percentage of our products that we license through third-party
distributors may change in the future as a result of the restructuring of our
worldwide sales force and our agreement with Rand.

Our service revenue is derived from the sale of software maintenance contracts
and the performance of training and consulting services and has a lower gross
profit margin than license revenue. Service revenue increased 16% in 1997 and
22% in 1998. This increase is the result of growth in our installed customer
base and increased training and consulting services performed for these
customers, offset by a decline in the Computervision-installed base. We expect
service revenue to continue to increase in both absolute dollars and as a
percentage of total revenue in 1999.

We derived 62%, 57%, and 56% of our total revenue from sales to international
customers in 1996, 1997, and 1998, respectively. The decrease in the percentage
of revenue derived from international sales since 1996 is attributable primarily
to: (i) the strengthening of the dollar in relation to the yen and the major
European currencies; (ii) the reluctance of Computervision customers, which were
predominantly overseas, to acquire additional licenses as a result of
Computervision's deteriorating financial condition prior to the merger; and
(iii) weaker than anticipated results in the Asia/Pacific region. Direct export
sales were $130.8 million, $148.5 million, and $115.2 million in 1996, 1997, and
1998, respectively.

- --------------------------------------------------------------------------------


COST OF REVENUE

Our cost of license revenue consists of costs associated with reproducing and
distributing software and documentation, royalties, and the amortization of
capitalized computer software costs. Cost of license revenue as a percent of
total revenue has been 2% for each of the last three years.

Our cost of service revenue includes costs associated with training and
consulting personnel, such as salaries and related costs and travel, and costs
related to software maintenance, including costs incurred for customer support
personnel and the release of maintenance updates. The increase in our cost of
service revenue resulted primarily from growth in the staffing necessary to
generate and support increased worldwide service revenue and to provide ongoing
quality customer support to our installed base. Cost of service revenue as a
percent of total revenue has been 13% for each of the last three years.


OPERATING EXPENSES

All operating expense categories, including cost of revenue, in 1996, 1997, and
1998 were impacted by the acquisition and restructuring nonrecurring charges
taken. See Note B.


SALES AND MARKETING

Our sales and marketing expenses primarily include salaries, sales commissions,
travel, and facility costs. These costs increased 17% in 1997 and 2% in 1998
with the 1997 change principally due to worldwide expansion of the sales force
and sales commissions associated with the sale of software and training and
consulting services. Total sales and marketing employees were 2,152 in 1996,
2,395 in 1997, and 2,440 in 1998. We expect our worldwide sales and marketing
organization to remain at or below the 1998 level given that sales to small
businesses will be managed by Rand A Technology Corporation under an agreement
beginning in 1999. International sales and marketing expenses represented 63% of
total sales and marketing expenses in 1996, 62% in 1997, and 59% in 1998.


RESEARCH AND DEVELOPMENT 

Our research and development expenses consist principally of salaries and
benefits, expenses associated with product translations, costs of computer
equipment used in software development, and facility expenses. Compared to the
prior years, research and development expenses increased 17% in 1997 and were
flat in 1998. The steady level of spending in 1998 compared to 1997 is primarily
attributable to the impact of workforce reductions and lower depreciation
related to write-offs of excess fixed assets associated with the Computervision
merger offset by our continued investment in research and development,
particularly in relation to the Windchill product line. We expect our investment
in research and development to increase in absolute dollars in 1999.


GENERAL AND ADMINISTRATIVE

Our general and administrative expenses include the costs of our corporate,
finance, information technology, human resources, and administrative functions.
These costs increased 12% in 1997 and decreased 5% in 1998. The increase in 1997
resulted primarily from the hiring of additional employees and spending to
upgrade internal information management systems. The decrease in these expenses
in 1998 was principally due to the impact of workforce reductions and lower
depreciation related to write-offs of excess fixed assets associated with the
Computervision merger.

ACQUISITION AND NONRECURRING CHARGES 

ICEM. In June 1998, we acquired ICEM Technologies (ICEM), a division of Control
Data Systems, Inc., for approximately $41 million in cash. Headquartered in
Frankfurt, Germany, ICEM provides advanced surfacing and reverse engineering
software tools used by body and styling engineers in the automotive and
aerospace industries. The acquisition was accounted for as a purchase.
Accordingly, we allocated the purchase price to the assets acquired and
liabilities assumed based on our estimates of fair value. The fair value
assigned to intangible assets acquired consisted of purchased in-process
research and development (R&D), developed technology, an assembled workforce,
and trade names. The amounts allocated to tangible and intangible assets
acquired less the liabilities assumed exceeded the purchase price by
approximately $7 million. This excess value over the purchase price was
allocated to reduce proportionately the values assigned to long-term assets and
purchased in-process R&D in determining their values. The values assigned
included $2.1 million for net assets acquired, $28.9 million for purchased
in-process R&D, $8.0 million for developed technology, $1.6 million for an
assembled workforce, and $1.0 million for trade names. The operating results of
ICEM have been included in our results of operations from the date of
acquisition.

In the opinion of management, the purchased in-process R&D had not yet reached
technological feasibility and had no alternative future use. Accordingly, we
recorded a nonrecurring charge of $28.9 million during the third quarter of
1998. The value assigned to purchased in-process R&D was determined by
identifying research projects for which technological feasibility had not been
established. The value was determined by estimating the costs to develop the
purchased in-process R&D into commercially viable products, estimating the
resulting net cash flows from such products, and discounting the net cash flows
back to their present value. The estimates were based on the following major
assumptions:

 .    Aggregate revenue was estimated to grow at a compound rate of 33% over the
     first five years and 14% thereafter.

 .    Cost of revenue for the purchased in-process technology, expressed as a
     percentage of revenue, was estimated to decline from 20% to 10% through
     2006. These percentages were based on ICEM's average historical cost of
     revenue, and reflect future economies of scale.

 .    Cost to complete the purchased in-process technology was estimated to be
     $1.5 million for 1998, $4.4 million for 1999, and $600,000 for 2000.

 .    Selling, general, and administrative expenses were estimated to be 29% of
     revenue for all periods, consistent with ICEM's historical average.

The net cash flows also considered net working capital requirements and capital
spending needs related to the purchased in-process technology. The 24% rate we
used to discount net cash flows for the in-process technology to present value
was based on the weighted average cost of capital and took into account the
uncertainty surrounding the successful development of the purchased in-process
technology.

If these projects are not successfully developed, future revenue and
profitability may be adversely affected. Additionally, the value of other
intangible assets acquired may become impaired.

Computervision. In connection with the Computervision merger, we incurred a
nonrecurring charge of $76.8 million for merger-related integration,
consolidation, and transaction costs. The charge included $18.1 million of
severance and termination benefits related to the elimination of approximately
450 positions, $12.7 million for the write-off of assets, $8.2 million for
transaction costs, $17.4 million of contract costs associated with revised
estimates, $7.2 million for the closing of leased facilities, and $13.2 million
of lease termination and other costs. Most of these costs, except for certain
contract costs and costs related to leased facilities, were incurred in 1998. We
also incurred an extraordinary after-tax charge of $19.0 million related to the
write-off of deferred financing costs and other prepayment costs associated with
our payment of $275.7 million for indebtedness of Computervision existing at the
time of the merger. See Notes B and G.

Our results for 1997 include a nonrecurring charge of $45.0 million related to
the restructuring of the Computervision software business in order to reduce
costs and improve operating results in future periods by reducing personnel by
approximately 300 positions and closing certain facilities.

Our results for 1996 include a nonrecurring charge of $14.5 million, which
includes $11.0 million of restructuring costs associated with the implementation
of ongoing cost savings, primarily personnel reductions of approximately 100
positions in R&D, sales and marketing, and closing certain facilities.

Reflex. In July 1996, we acquired project modeling and management software
(Reflex) technology from Greenshire License Co. for $32.1 million. Of the total
purchase price, we issued 226,000 shares of our common stock with a fair value
of $5.0 million at the time of the acquisition and paid cash of $22.1 million in
1996 and $5.0 million in 1997. The acquisition was accounted for as a purchase.
The fair value assigned to intangible assets acquired consisted of in-process
R&D related to a research project, which had not yet reached technological
feasibility and had no alternative future uses. As a result, at the date of
acquisition, the $32.1 million allocated to purchased in-process R&D was
recorded as a nonrecurring charge. The value was determined by estimating the
costs to develop the purchased in-process R&D into a commercially viable
product, estimating the resulting net cash flows from such product, and
discounting the net cash flows back to their present value. The net cash flows
also considered net working capital requirements and capital spending needs
related to the in-process products. The discount rate of 30% used for Reflex
took into account the uncertainty surrounding the successful development of the
purchased in-process technology. The assumptions we used reflected the fact that
Reflex did not have any other assets or revenue, and was a development-stage
enterprise.

The operating results of Reflex have been included in our results of operations
from the date of acquisition.


INTEREST EXPENSE

Our interest expense related primarily to debt incurred by Computervison prior
to the merger that we paid off in the second quarter of 1998. See Note G.


INTEREST INCOME

Interest income relates to the earnings on the investment of our excess cash
balance in various financial instruments. The 1997 increase in interest income
was due primarily to higher average investment balances. The 1998 increase
resulted from higher average annual yields.


OTHER EXPENSE

A large portion of our revenue and expenses is transacted in foreign currencies.
In order to reduce our exposure to fluctuations in foreign exchange rates, from
time to time we engage in hedging transactions involving the use of foreign
exchange forward contracts and foreign exchange option contracts in the primary
European and Asian currencies. Our other expense increased primarily due to the
costs of the hedging contracts, the gain or loss from the translation of results
for subsidiaries for which the U.S. dollar is the functional currency, and other
charges incurred in connection with financing customer contracts. See Note A.


INCOME TAXES

Our effective income tax rate was 34% in 1996, 57% in 1997, and 48% in 1998. The
difference between our effective and the statutory federal tax rate was due
primarily to the nondeductibility of certain expenses included in the
acquisition-related charges in 1998 and losses of Computervision in 1997. See
Note F.


EXTRAORDINARY CHARGE

The extraordinary charge incurred in 1998 related to the early repayment of the
debt that Computervision had incurred prior to our merger. See Note G.


LIQUIDITY AND CAPITAL RESOURCES

Our operating activities, the proceeds from our issuance of stock under stock
plans, and existing cash and investments provided sufficient resources to fund
our employee growth, capital asset needs, stock repurchases, acquisitions, and
debt repayment, in all years presented.

As of September 30, 1998, cash and investments totaled $426.2 million, down from
$568.7 million at September 30, 1997. The primary reason for the decrease in
cash and investments during 1998 was the repayment of $275.7 million of
Computervision debt. Our investment portfolio is diversified among security
types, industries, and individual issuers. Our investments are generally liquid
and investment grade. The portfolio is primarily invested in short-term
securities to minimize interest rate risk and to facilitate rapid deployment in
the event of immediate cash needs.

Cash generated from operating activities was $237.0 million in 1996, $195.8
million in 1997, and $181.9 million in 1998, net of cash expenditures for
nonrecurring charges of $12.0 million in 1996, $38.9 million in 1997, and $62.3
million in 1998.

In 1996, 1997, and 1998, we acquired $41.1 million, $36.2 million, and $35.8
million, respectively, of capital equipment consisting principally of computer
equipment, software, and office equipment. We spent $23.2 million in 1996, $5.0
million in 1997, and $40.6 million in 1998 to acquire businesses. These
expenditures were partially offset by $30.1 million received from the sale of a
Computervision business unit in June 1997.

                                                                              29

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
- --------------------------------------------------------------------------
OPERATIONS
- ----------


We used net cash for financing activities in 1996, 1997, and 1998, primarily to
repurchase $66.6 million, $184.8 million, and $50.0 million, respectively, of
our stock, and to pay off the Computervision debt in 1998 of $275.7 million.
These expenditures were partially offset by proceeds of $43.8 million, $66.3
million, and $70.4 million in 1996, 1997, and 1998, respectively, from the
issuance of our common stock under our stock plans. As a result of the exchange
of certain stock options held by non-executive employees, we expect proceeds
from stock option exercises to be lower in 1999. See Note J.

In May 1994, we announced that our Board of Directors had authorized a plan
allowing us to repurchase up to 6.0 million shares of our common stock. In
September 1997, our Board of Directors increased that number to 12.0 million. In
October 1997, in anticipation of the Computervision merger, we suspended
repurchases and the Board of Directors rescinded its authorization of the
repurchase program in November 1997. Under the program, we repurchased a total
of 11.6 million shares at a cost of $260.0 million. In September 1998, our Board
of Directors authorized a new share repurchase program for the repurchase of up
to 20.0 million shares. During 1998, we purchased 4.7 million shares at a cost
of $50.0 million. The repurchased shares will be used to issue shares for stock
option exercises, employee stock purchase plans, and potential acquisitions.

We believe that existing cash and short-term investments together with cash
generated from operations and the issuance of common stock under our stock plans
will be sufficient to meet our working capital, financing, and capital
expenditure requirements through at least 1999.


NEW ACCOUNTING PRONOUNCEMENTS

In accordance with recently issued accounting pronouncements, we will be
required to comply with certain changes in accounting rules and regulations. See
Note A.


FINANCIAL RISK MANAGEMENT

We face exposure to financial market risks, including adverse movements in
foreign currency exchange rates and changes in interest rates. These exposures
may change over time as business practices evolve and could have a material
adverse impact on our financial results. Our primary exposure has been related
to local currency revenue and operating expenses in Europe and the Asia/Pacific
region. Historically, we have hedged currency exposures associated with certain
accounts receivable denominated in local currencies and certain anticipated
foreign currency revenue transactions. The goal of our hedging activity is to
offset the impact of currency fluctuations on certain local currency accounts
receivable and foreign currency revenue transactions. The success of this
activity depends upon forecasts of transaction activity denominated in various
currencies. To the extent that these forecasts are overstated or understated
during periods of currency volatility, we could experience unanticipated
currency gains or losses. Outstanding forward foreign exchange contracts at
September 30, 1998 matured within one month, and did not have a material impact
on our financial results.

The carrying amounts reflected in the consolidated balance sheets for cash and
cash equivalents, accounts receivable, and accounts payable approximate fair
value at the balance sheet date due to the short maturities of these
instruments.

We maintain investment portfolio holdings of various issuers, types, and
maturities. These securities are generally classified as available for sale, and
consequently, are recorded on the balance sheet at fair value with unrealized
gains or losses included in stockholders' equity. Given the short maturities and
investment grade quality of the portfolio holdings at September 30, 1998, a
sharp rise in interest rates should not have a material adverse impact on the
fair value of our investment portfolio. As a result, we do not currently hedge
these interest rate exposures.

The following table presents hypothetical changes in fair values in our
financial instruments at September 30, 1998 that are sensitive to changes in
interest rates. Our modeling technique measures the change in fair value arising
from selected potential changes in interest rates. Movements in interest rates
of plus or minus 50 basis points ("BP") and 100 BP reflect immediate
hypothetical shifts in the fair value of these investments. Fair value
represents the market principal plus accrued interest and dividends of certain
interest-rate-sensitive securities considered cash equivalents or investments
for financial reporting purposes at September 30, 1998.

IMPORTANT RISK FACTORS AFFECTING RESULTS

We caution you that our performance is subject to risks and uncertainties. There
are a variety of important factors like those that follow that may cause our
future results to differ materially from those projected in any of our
forward-looking statements made in this Annual Report or otherwise.


FLUCTUATIONS IN OPERATING RESULTS

While our sales cycle varies substantially from customer to customer, we usually
realize a high percentage of our revenue in the third month of each fiscal
quarter and this revenue tends to be concentrated in the latter half of that
month. Our orders early in a quarter will not generally occur at a rate which,
if sustained throughout the quarter, would be sufficient to assure that we will
meet our revenue targets for any particular quarter. Accordingly, our quarterly
results may be difficult or impossible to predict prior to the end of the
quarter. Any inability to obtain orders in large volumes or to make shipments in
the period immediately preceding the end of any particular quarter may cause the
results for that quarter to fall short of our revenue targets. In addition, our
operating expenses are based on expected future revenue and are relatively fixed
for the short term. As a result, a revenue shortfall in any quarter could cause
our earnings for that quarter to fall below expectations as well. Any failure to
meet our quarterly revenue or earnings targets could adversely impact the market
price of our stock.

Because our sales incentive structure is weighted more heavily toward the end of
the fiscal year, the rate of revenue growth for the first quarter historically
has been lower than that for the fourth quarter of the immediately preceding
fiscal year. This incentive structure also makes it more difficult to predict
first quarter results.

In addition, the levels of quarterly or annual software revenue in general, or
for particular geographic areas, may not be comparable to those achieved in
previous periods.

STOCK MARKET VOLATILITY

Market prices for securities of software companies have generally been volatile.
In particular, the market price of our common stock has been and may continue to
be subject to significant fluctuations.

In addition, a large percentage of our common stock traditionally has been held
by institutional investors. Consequently, actions with respect to our common
stock by certain of these institutional investors could have a significant
impact on the market price of the stock. For more information, please see our
proxy statement with respect to our most recent annual meeting of stockholders
and Schedules 13D and 13G filed with the U.S. Securities and Exchange Commission
(SEC) with respect to our common stock.


MARKET GROWTH

Any of our projections for revenue growth assume that the overall demand for
products in the mechanical CAD/CAM/CAE industry will continue to grow. There
could be an adverse impact on our operating results in any quarter in which this
assumption proves to be incorrect.


RAPID TECHNOLOGICAL AND MARKET CHANGES

The mechanical CAD/CAM/CAE and enterprise information management industries are
highly competitive and are characterized by rapid technological advances.
Accordingly, our ability to realize our expectations will depend on:

 .    our success at enhancing our current offerings

 .    our ability to develop new products and services that keep pace with
     developments in technology

 .    our ability to meet evolving customer requirements, especially
     ease-of-use requirements

 .    our ability to deliver those products through appropriate distribution   
     channels, and

 .    our ability to license technology from third parties.

This will require, among other things, that we:

 .    correctly anticipate customer needs and price our products
     competitively

 .    hire and retain personnel with the necessary skills and creativity

 .    provide adequate funding for development efforts, and

 .    manage distribution channels effectively.

In addition, our CAD/CAM/CAE software has historically been available on a
variety of platforms. We are aware of efforts by competitors to focus on single
platform applications, particularly Windows-based platforms. There can be no
assurance that we will continue to have a competitive advantage with multiple
platform applications.

                                                                        31
<PAGE>
 
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
- --------------------------------------------------------------------------
OPERATIONS
- ----------


We continue to enhance our existing products by releasing updates. Those product
updates will be less frequent than in the past to permit customers to absorb
changes more effectively. Our competitive position and operating results could
suffer if:

 .    we fail to anticipate or to respond adequately to customer requirements or
     to technological developments, particularly those of our competitors

 .    we delay the development, production, testing, marketing, or availability
     of new or enhanced products or services, or

 .    customers fail to accept such products or services.

The success of our new Windchill product line will depend in part on the
market's evaluation of its ease of use, its full functionality, and its ability
to support a large user base. Since this product line only became available in
the latter half of 1998, it is not possible to assess the market's acceptance of
this product line at this time.


POSSIBILITY OF NEW PRODUCT DELAYS

As is common in the computer software industry, we may from time to time
experience delays in our product development and "debugging" efforts. Our
financial performance could be hurt by significant delays in developing,
completing, or shipping new or enhanced products. Among other things, such
delays could cause us to incorrectly predict the fiscal quarter in which we will
realize revenue from the shipment of the new or enhanced products and give our
competitors a greater opportunity to market competing products.


SUCCESSFUL IMPLEMENTATION OF NEW INITIATIVES

We have a history of rapid growth and development as an organization. Part of
our success has resulted from our ability to implement new initiatives. Our
future operating results will continue to depend upon:

 .    the success of our efforts to integrate Computervision's operations on a
     worldwide basis

 .    market acceptance of the new Windchill product line, which has a longer
     sales cycle than our other products

 .    the success of our sales force reorganization initiative, including Rand's
     success with sales to smaller customers

 .    market reaction to the repricing and repackaging of our Pro/ENGINEER
     product line, and

 .    our ability to increase revenue growth in the Asia/Pacific region.


Additionally, our success could also be affected by our ability to:

 .    develop additional applications for the Windchill product line

 .    generate and fill current software license orders, and

 .    adequately manage exposure to foreign currency movements.


RISKS ASSOCIATED WITH ACQUISITIONS

We have increased our product range and customer base in the recent past, due in
part to acquisitions. We may acquire additional businesses or product lines in
the future. The success of any acquisition may be dependent upon our ability to
integrate the acquired business or products successfully and to retain key
personnel and customers associated with the acquisition. If we fail to do so, or
if the costs of or length of time for integration increase significantly, it
could cause our actual results to differ from those projected in our
forward-looking statements.

In addition, acquisitions may result in the allocation of purchase price to
in-process R&D. For example, for the year ended September 30, 1998, we recorded
in-process R&D expense of approximately $28.9 million in connection with our
acquisition of ICEM. The SEC has recently raised issues regarding the
methodologies used and allocation of purchase price to in-process R&D and has
required some companies to adjust or restate prior periods to reduce allocations
to in-process R&D, thereby increasing intangible assets and future amortization
expense. While we believe that our in-process R&D allocation is appropriate, if
the SEC were to require us to change the allocation, this would result in a
higher amortization expense, which would adversely impact our future operating
results.


COMPETITION

There are an increasing number of competitive mechanical CAD/CAM/CAE products.
Increased competition and market acceptance of these products could have a
negative effect on our pricing and revenues, which could adversely affect our
operating results. Our Windchill product line expands the breadth of our
offerings into product information management. We are a relatively new entrant
into this area and may be competing with more mature products that may have an
established customer base as well as greater functionality.


DEPENDENCE ON KEY PERSONNEL

Our success depends upon our ability to attract and retain highly skilled
technical, managerial, and sales personnel. While we have not experienced any
significant difficulty in hiring or retaining

32
<PAGE>
 
qualified personnel to date, competition for such personnel in the high
technology industry is intense. We assume that we will continue to be able to
attract and retain such personnel. The failure to do so, however, could have a
material adverse effect on our future operating results.


RISKS ASSOCIATED WITH INTERNATIONAL BUSINESS

A significant portion of our business comes from outside the United States.
Accordingly, our performance could be adversely affected by ongoing economic
uncertainties in the Asia/Pacific region and other world economies. Another
consequence of significant international business is that a large percentage of
our revenue and expenses are denominated in foreign currencies which fluctuate
in value. Although we may enter into foreign exchange forward contracts and
foreign exchange option contracts to offset a portion of the foreign exchange
fluctuations, unanticipated events may materially impact our results. Other
risks associated with international business include:

 .    unexpected changes in regulatory practices and tariffs
   
 .    staffing and managing foreign operations
   
 .    longer collection cycles in certain areas
   
 .    potential changes in tax laws
   
 .    greater difficulty in protecting intellectual property rights, and
   
 .    general economic and political conditions.


PROTECTION OF INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS

Our software products are proprietary to PTC. We protect our intellectual
property rights by relying on copyrights, trademarks, patents, and common law
safeguards, including trade secret protection, as well as restrictions on
disclosures and transferability contained in our agreements with other parties.
Despite these measures, there can be no assurance that the laws of all relevant
jurisdictions will afford the same protections to our products and intellectual
property as the laws of the United States. The software industry is
characterized by frequent litigation regarding copyright, patent, and other
intellectual property rights. While we have not, to date, had any significant
claims of this type asserted against us, there can be no assurance that someone
will not assert such claims against us with respect to existing or future
products or that, if asserted, we would prevail in such claims. In the event a
lawsuit of this type is filed, it could result in significant expense to us and
divert the efforts of our technical and management personnel, whether or not we
ultimately prevail.


LEGAL PROCEEDINGS

Certain class action lawsuits have been filed against us and certain of our
current and former officers and directors claiming violations of the federal
securities laws based on alleged misrepresentations regarding our anticipated
revenue and earnings for the third quarter of 1998. We believe the claims are
without merit and we intend to defend them vigorously. We cannot predict the
ultimate resolution of these actions at this time, and there can be no assurance
that the litigation will not have a material adverse impact on our financial
condition or results of operations.


YEAR 2000 COMPUTER SYSTEMS COMPLIANCE

Concerns have been widely expressed regarding the inability of certain computer
programs to properly process certain date information, particularly beyond the
year 1999. These concerns focus on the impact of the Year 2000 problem on
business operations and the potential costs associated with identifying and
addressing the problem.

State of Readiness. We have developed a Year 2000 readiness plan focusing on:
(i) assessing the readiness of our product offerings, internal business systems,
and major vendors and suppliers; (ii) addressing known risks; and (iii) planning
and budgeting for reasonably likely contingencies.

We are in the process of testing our current product offerings for Year 2000
compliance. Based on our review to date, we believe that our principal product
offerings are largely Year 2000-compliant in their current versions. While
testing of our current product offerings is complete, we are still in the
process of making modifications to those currently offered systems that are not
compliant and anticipate that these corrections will be complete by March 31,
1999. We are conducting only limited testing of products that are no longer
offered, and thus the Year 2000 compliance of such products is generally not
known. Many of these untested products are previous releases of current
offerings. Our customers can upgrade many of these products to achieve Year 2000
compliance.

We are also in the process of reviewing and upgrading our internal information
technology and business systems, both domestically and internationally, to
ensure Year 2000 readiness. This process is expected to be complete by March 31,
1999 with respect to the majority of our mission-critical systems. We expect to
continue testing our internal systems and to undertake necessary corrective
measures throughout calendar 1999.

                                                                              33
<PAGE>
 
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
- --------------------------------------------------------------------------------
OPERATIONS
- ----------



Finally, we have commenced a program to survey the Year 2000 readiness of our
major vendors and suppliers, with a particular focus on the Year 2000 readiness
of our mission-critical vendors and suppliers. This process is expected to be
complete by March 31, 1999. Where we believe that a particular vendor or
supplier poses unacceptable Year 2000 risks, we will identify an alternative
supply source.

Cost of Year 2000 Compliance. Costs incurred in our Year 2000 compliance effort
include the allocation of personnel to testing our products and systems as well
as to upgrading internal systems. We have identified approximately $3.0 million
in costs already incurred and estimate that another $3.0 to $6.0 million may be
spent on our compliance project. Costs are expensed as incurred. While our
compliance evaluation and remediation project is not yet complete, we do not at
this time foresee a material impact on our business or operating results from
the Year 2000 problem. We cannot, of course, predict the nature or materiality
of the impact on our operations or operating results of Year 2000 disruption by
parties over whom we have no control. Furthermore, the purchasing patterns of
our customers or potential customers may be affected by Year 2000 issues if they
must expend significant resources to correct their own systems. As a result they
may have fewer funds available to purchase our products and services.

Risk of Year 2000 Issues and Contingency Plans. Our worst-case Year 2000
scenarios would include: (i) undetected errors or uncorrected defects in our
current product offerings; (ii) corruption of data contained in our internal
information systems; and (iii) the failure of infrastructure services provided
by third parties and government agencies (e.g., electricity, phone service,
Internet services, etc.). We are in the process of reviewing our contingency
planning in all of these areas and expect the plans to include, among other
things, the availability of support personnel to assist with customer support
issues, manual "work arounds" for internal software failure, and substitution of
systems, if needed.


EURO CONVERSION

On January 1, 1999, eleven of the fifteen member countries of the European Union
are scheduled to establish fixed conversion rates between their existing
sovereign currencies and the euro, making the euro their common legal currency
on that date. There will be a transition period between January 1, 1999 and
January 1, 2002, during which the old currencies will remain legal tender in the
participating countries as denominations of the euro. During the transition
period, public and private parties may pay for goods and services using either
the euro or the participating country's former currency on a no compulsion, no
prohibition basis. Conversion rates, however, will no longer be computed
directly from one former currency to another. Instead, a triangular process will
apply whereby an amount denominated in one former currency will first be
converted into the euro. The resultant euro-denominated amount will then be
converted into the second former currency.

We are currently evaluating the business implications of conversion to the euro,
including technical adaptation of information technology and other systems to
accommodate euro-denominated transactions, long-term competitive implications of
the conversion, and the effect on market risk with respect to financial
instruments. At this time, we do not believe that the euro's introduction will
have a material impact on our business during the transition period.

- --------------------------------------------------------------------------------


A. SUMMARY OF SIGNIFICANT
   ACCOUNTING POLICIES


BUSINESS

Parametric Technology Corporation develops, markets, and supports a
comprehensive suite of integrated product development and information management
software. We operate in a single industry segment--computer software and related
services.


BASIS OF PRESENTATION

Our fiscal year-end is September 30. The consolidated financial statements
include the parent company and its wholly owned subsidiaries, including those
operating outside the U.S. All significant intercompany balances and
transactions have been eliminated in the financial statements. Certain
reclassifications have been made for consistent presentation. We prepare our
financial statements under generally accepted accounting principles that require
management to make estimates and assumptions that affect the amounts reported
and the related disclosures. Actual results could differ from these estimates.

As described in Note B, in January 1998, we merged with Computervision
Corporation. The merger was accounted for as a pooling of interests.
Accordingly, the accompanying consolidated financial statements and notes have
been restated for all periods presented.


FOREIGN CURRENCY TRANSLATION

For our foreign operations where the functional currency is the local currency,
we translate assets and liabilities at rates in effect at the balance sheet date
and record translation adjustments in stockholders' equity. For our foreign
operations where the U.S. dollar is the functional currency, we translate
monetary assets and liabilities using exchange rates in effect at the balance
sheet date and nonmonetary assets and liabilities at historical rates and record
translation adjustments in income. We translate income statement amounts at
average rates for the period. Transaction gains and losses are recorded in other
expense in the statement of income.


REVENUE RECOGNITION

Our revenue is derived from the licensing of computer software products and from
service revenue consisting of training, consulting, and maintenance. License
revenue is recognized upon shipment, unless collection is not reasonably
assured. Revenue from software maintenance contracts is recognized ratably over
the contract period. Revenue from consulting and training is recognized upon
performance. Other service revenue is recognized ratably over the contractual
period.


CASH, CASH EQUIVALENTS, AND INVESTMENTS

Our cash is invested in debt instruments of financial institutions, government
entities, corporations, and mutual funds. We have established guidelines
relative to credit ratings, diversification, and maturities that maintain safety
and liquidity. Our cash equivalents include highly liquid investments with
maturity periods of three months or less when purchased. Our short-term
investments include those investments with maturities in excess of three months
but less than one year. Our marketable investments are those with maturities in
excess of one year but less than two years. Our cash equivalents and short-term
and marketable investments are classified as available for sale and reported at
fair value with unrealized gains and losses included in stockholders' equity. We
have not had any significant losses related to our investments.


CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS

The amounts reflected in the consolidated balance sheets for cash and cash
equivalents, accounts receivable, and accounts payable approximate their fair
value due to their short maturities. Financial instruments that potentially
subject us to concentration of credit risk consist primarily of investments,
trade receivables, and derivatives. Our cash, cash equivalents, investments, and
derivatives are held with financial institutions with high credit standings. Our
customer base consists of large numbers of geographically diverse customers
dispersed across many industries. As a result, concentration of credit risk with
respect to trade receivables is not significant.


TRANSFER OF FINANCIAL ASSETS

We offer our customers the option to purchase software and services through
payment plans, financing, or leasing contracts. In general, we transfer future
payments under certain of these contracts to financing institutions on a
non-recourse basis. We record such transfers as sales of the related accounts
receivable when we surrender control of such receivables under the provisions of
Statement of Financial Accounting Standards (SFAS) No. 125, Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.
Fair market value of all service assets and liabilities were immaterial for all
periods.


                                                                    

                                                                        39

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


DERIVATIVES

Derivatives are financial instruments whose value is derived from one or more
underlying financial instruments, such as foreign currency. We enter into
derivative transactions, specifically foreign exchange forward (forward)
contracts and foreign exchange option (option) contracts, to manage our exposure
to fluctuations in foreign exchange rates. The contracts are primarily in
European currencies and Japanese yen and have maturities less than one year. Any
derivative we enter into is designated at inception as a hedge of risks
associated with specific assets, liabilities, or future commitments and is
monitored to determine if it remains an effective hedge. The effectiveness of
the derivative as a hedge is based on changes in its market value being highly
correlated with changes in market value of the underlying hedged items. We do
not enter into or hold derivatives for trading or speculative purposes.

We use forward contracts to hedge specific foreign currency denominated
receivables. These contracts, which are one year or less in length, require us
to exchange foreign currencies for U.S. dollars at maturity at rates agreed to
at inception of the contracts. We enter into transactions denominated in foreign
currencies and include the exchange gain or loss arising from such transactions
in other expense. As of September 30, 1997 and 1998, we had approximately $50.2
million and $49.8 million, respectively, of forward contracts outstanding.
Unrealized and realized gains and losses associated with exchange-rate
fluctuations on forward contracts are immaterial for all periods presented. Cash
flows from forward contracts are classified with the related receivables.

From time to time, we purchase option contracts to limit potential losses from
adverse exchange-rate movements on certain anticipated revenue transactions.
Premiums to purchase option contracts are capitalized in other current assets
and amortized to other expense over the life of the contract. Gains on option
contracts, if any, are included in license and service revenue in the period in
which the related local-currency revenue is reported. These amounts were
immaterial for all periods presented. There were no outstanding option contracts
at September 30, 1997 or 1998.


PROPERTY AND EQUIPMENT

Property and equipment are recorded at cost and depreciated using the
straight-line method over their estimated useful lives, typically three to eight
years. Leasehold improvements are amortized over the shorter of their useful
lives or the remaining terms of the related leases. Property and equipment under
capital leases are amortized over the lesser of the lease terms or their 
estimated useful lives. Maintenance and repairs are charged to expense when 
incurred; additions and improvements are capitalized. When an item is sold or
retired, the cost and related accumulated depreciation is relieved, and the 
resulting gain or loss, if any, is recognized in income.


COMPUTER SOFTWARE COSTS

We incur costs to develop and purchase computer software to be licensed or
otherwise marketed to customers. Development costs incurred in the research and
development of new software products and enhancements to existing products are
expensed in the period incurred, unless these costs qualify for capitalization.
Capitalized computer software costs are amortized over the economic lives of the
related products, typically three to five years, beginning at their initial
shipment date. Capitalized computer software costs of $1.7 million and $8.7
million, net of accumulated amortization of $8.0 million and $9.9 million, are
included in other assets at September 30, 1997 and 1998. Amortization charged to
expense was $3.7 million, $2.6 million, and $1.9 million for 1996, 1997, and
1998.


INTANGIBLE ASSETS

Included in our other assets are values attributable to intangible assets
acquired, such as goodwill and trademarks, which are amortized over seven years,
and assembled workforces, which are amortized over five to seven years.
Amortization charges related to intangible assets, the majority of which were
recorded in general and administrative expenses, totaled $1.7 million for 1996,
and $1.6 million for 1997 and 1998.

Management regularly evaluates the net realizable value of long-lived assets,
including property and equipment, computer software costs, and intangible
assets, relying on a number of factors including operating results, business
plans, budgets, and economic projections.


INCOME TAXES

Our income tax expense includes U.S. and international income taxes. Certain
items of income and expense are not reported in tax returns and financial
statements in the same year. The tax effect of these differences are reported as
deferred tax assets and liabilities. Deferred tax assets are recognized, net of
valuation allowances, for the estimated future tax effects of deductible
temporary differences and tax operating loss and credit carryforwards. Changes
in deferred tax assets and liabilities are recorded in the provision for income
taxes.

EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 128, Earnings per Share (EPS). This standard requires dual presentation of
basic and diluted EPS on the face of the income statement and requires a
reconciliation of the numerators and denominators of basic and diluted EPS
calculations. We adopted this standard during the first quarter of fiscal 1998.
Accordingly, all prior period EPS data has been restated to conform to the
provisions of SFAS No. 128.

Basic EPS is calculated by dividing net income by the weighted average number of
shares outstanding during the period. Diluted EPS is calculated by dividing net
income by the weighted average number of shares outstanding plus the dilutive
effect of outstanding stock options using the "treasury stock" method. The

Options to purchase shares of the Company's common stock of 1.8 million shares
for 1996, 6.3 million shares for 1997, and 11.7 million shares for 1998 were
outstanding but were not included in the computations of diluted EPS because the
price of the options was greater than the average market price of the common
stock for the period reported.

STOCK-BASED COMPENSATION

We account for stock-based compensation using the intrinsic value method
prescribed in Accounting Principles Board Opinion No. 25, Accounting for Stock
Issued to Employees (APB No. 25), and related interpretations. Under APB No. 25,
no compensation cost is recognized because the option price is equal to the
market price of the underlying stock on the date of grant. An alternative method
of accounting is SFAS No. 123, Accounting for Stock-Based Compensation. Under
SFAS No. 123, employee stock options are valued at the grant date using a
valuation model, and compensation cost is recognized ratably over the vesting
period. The impact of recording stock-based compensation under the provisions of
SFAS No. 123 is disclosed in Note J.

NEW ACCOUNTING PRONOUNCEMENTS

In 1997, the FASB issued SFAS No. 130, Reporting Comprehensive Income, which
establishes standards for the reporting and the display of comprehensive income
and its components (revenue, expenses, gains, and losses). During 1997, the FASB
also issued SFAS No. 131, Disclosure about Segments of an Enterprise and Related
Information, which changes the way public companies report information about
operating segments. SFAS No. 131, which is based on the management approach to
segment reporting, establishes requirements to report selected segment
information quarterly and to report entity-wide disclosures about products and
services, major customers, and the material countries in which the entity holds
assets and reports revenue. We will adopt SFAS No. 130 and SFAS No. 131 in
fiscal 1999 and do not expect that the adoptions will have a material impact on
the consolidated financial statements.

In October 1997, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 97-2, Software Revenue Recognition, which provides
guidance on applying generally accepted accounting principles in recognizing
revenue on software transactions and supersedes SOP 91-1, Software Revenue
Recognition. We will adopt SOP 97-2 in fiscal 1999 and do not anticipate any
material impact on our revenue recognition policies or on our results of
operations.

In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded in current earnings or other
comprehensive income, depending on whether the derivative is designated as part
of a hedge transaction and, if it is, the type of hedge transaction. We will
adopt SFAS No. 133 in fiscal 2000. Our management anticipates that the adoption
of SFAS No. 133 will not have a significant effect on our consolidated financial
statements.


                                                                        41

B. ACQUISITIONS AND
   NONRECURRING CHARGES

ACQUISITIONS

ICEM. In June 1998, we acquired ICEM Technologies (ICEM), a division of Control
Data Systems, Inc., for approximately $41 million in cash. Headquartered in
Frankfurt, Germany, ICEM provides advanced surfacing and reverse-engineering
software tools used by body and styling engineers in the automotive and
aerospace industries. The acquisition was accounted for as a purchase.
Accordingly, we allocated the purchase price to the assets acquired and
liabilities assumed based on our estimates of fair value. The fair value
assigned to intangible assets acquired consisted of purchased in-process
research and development (R&D), developed technology, an assembled workforce,
and trade names. The amounts allocated to tangible and intangible assets
acquired less the liabilities assumed exceeded the purchase price by
approximately $7 million. This excess value over the purchase price was
allocated to reduce proportionately the values assigned to long-term assets and
purchased in-process R&D in determining their values. The values assigned
included $2.1 million for net assets acquired, $28.9 million for purchased
in-process R&D, $8.0 million for developed technology, $1.6 million for an
assembled workforce, and $1.0 million for trade names. The operating results of
ICEM have been included in our results of operations from the date of
acquisition. Our purchase of ICEM did not require presentation of pro forma
information.

In the opinion of management, the purchased in-process R&D had not yet reached
technological feasibility and had no alternative future use. Accordingly, we
recorded a nonrecurring charge of $28.9 million during the third quarter of
1998. The value assigned to purchased in-process R&D was determined by
identifying research projects for which technological feasibility had not been
established. The value was determined by estimating the costs to develop the
purchased in-process R&D into commercially viable products, estimating the
resulting net cash flows from such products, and discounting the net cash flows
back to their present value. The discount rate used included a factor that took
into account the uncertainty surrounding the successful development of the
purchased in-process technology. If these projects are not successfully
developed, future revenue and profitability may be adversely affected.
Additionally, the value of other intangible assets acquired may become impaired.

Computervision. In January 1998, we merged with Computervision Corporation by
issuing 11.6 million shares of common stock in exchange for all of the
outstanding common stock of Computervision. In connection with the
Computervision merger, we incurred a nonrecurring charge of $76.8 million for
merger-related integration, consolidation, and transaction costs in 1998, which
are described in the acquisition and nonrecurring charges activity table below.

As our fiscal year-end differed from Computervision's, we combined financial
information for dissimilar year-ends. Balance sheet information as of September
30, 1997 includes our financial position as of September 30, 1997 and
Computervision's as of December 31, 1997. Computervision's results of operations
for its fiscal years ended December 31, 1996 and December 31, 1997 were combined
with our results of operations for the fiscal years ended September 30, 1996 and
September 30, 1997. In order to conform Computervision's fiscal year-end to
ours, Computervision's results of operations for the three months ended December
31, 1997 were combined with our results of operations for the three months ended
January 3, 1998. Computervision's net loss of $20.2 million for the three months
ended December 31, 1997, which has been included in the consolidated statements
of income for the fourth quarter of fiscal 1997 and the first quarter of fiscal
1998, has been reflected as an adjustment to our beginning balance of fiscal
1998 accumulated deficit. Due to the change in Computervision's year-end, their
cash flow activity for the three-month period ended December 31, 1997 has been
shown as a separate component of the cash flow statement. Adjustments recorded
to conform Computervision's accounting policies to ours were not material to the
consolidated financial statements. The following table shows revenue and net
income of the separate companies during the period preceding the combination:

Reflex. In July 1996, we acquired project modeling and management software
(Reflex) technology from Greenshire License Co. for $32.1 million. Of the total
purchase price, we issued 226,000 shares of our common stock with a fair value
of $5.0 million at the time of the acquisition and paid cash of $22.1 million in
1996 and $5.0 million in 1997. The acquisition was accounted for as a purchase.
The fair value assigned to intangible assets acquired consisted of in-process
R&D related to a research project, which had not yet reached technological
feasibility and had no alternative future uses. As a result, at the date of
acquisition, the $32.1 million allocated to purchased in-process R&D was
recorded as a nonrecurring charge. The value was determined by estimating the
costs to develop the purchased in-process R&D into a commercially viable
product, estimating the resulting net cash flows from such product, and
discounting the net cash flows back to their present value. The discount rate
included a factor that took into account the uncertainty surrounding the
successful development of the purchased in-process technology. The operating
results of Reflex have been included in our consolidated results of operations
from the date of acquisition. Our purchase of Reflex did not require
presentation of pro forma information.

NONRECURRING CHARGES
Other nonrecurring charges related to actions taken as a result of cost saving
initiatives implemented during 1996 and 1997 by Computervision. These
restructuring costs were accrued and charged to expense in accordance with
management plans. We anticipate that a substantial portion of the remaining
nonrecurring amounts will be paid during 1999, except for certain long-term
obligations, principally related to facilities.

The following table summarizes all our acquisition and nonrecurring charges:

C. SALE OF A BUSINESS UNIT

In July 1997, Computervision sold a majority interest in its other services
business unit, which provided hardware support services, to CVSI, Inc. for $32.6
million in cash. Due to the sale of this business unit in 1997, we have
presented the revenue and expense of the other services business as a separate
operating item under the caption other services in our statements of income.
Other services operating and nonrecurring charges include the operating expenses
of the other services business and nonrecurring charges of $5.0 million in 1996
and $7.0 million in 1997 related to the prior proposed sale of this business
unit.


D. INVESTMENTS

The fair values of our investments have been determined through information
obtained from market sources and management estimates. We use a specific
identification cost method to determine the gross realized gains and losses on
the sale of our securities. Realized gains and losses on the sale of investments
were immaterial for 1996, 1997, and 1998.

For U.S. tax return purposes, net operating losses (NOLs) and tax credit
carryforwards are generally available to be carried forward to future years.
However, the Internal Revenue Code limits a corporation's use of NOLs and tax
credits after a change of more than 50% of the ownership of the corporation. Our
merger with Computervision in January 1998 changed their ownership more than
50%. This change limits our usage of the Computervision NOLs to $14.0 million
per year, and $196.0 million cumulatively through 2011. There are other
limitations imposed on the utilization of such NOLs that will further restrict
the recognition of such tax benefits. We have foreign NOLs that are also subject
to various limitations. Due to these limitations, we have recorded a valuation
allowance for the tax benefit of a majority of NOLs since realization of these
future benefits is not sufficiently assured. During 1998, we reduced our
valuation allowance $46.5 million primarily due to changes in ownership related
to the Computervision merger.


                                                                              45

G. DEBT

Our debt outstanding in 1997 consisted of the obligations of Computervision. As
described below, all such obligations were paid during the second quarter of
fiscal 1998. The total cash outlay for settlement of these obligations plus
accrued interest and related fees was $275.7 million. We incurred an
extraordinary after-tax charge of $19.0 million related to the write-off of
deferred financing costs and other prepayment costs associated with the payment
of these debt obligations. We paid interest of $27.3 million in 1996, $29.6
million in 1997, and $10.7 million in 1998.

                                                              September 30,

Notes payable to banks consisted of borrowings of our international subsidiaries
under certain lines of credit. These borrowings were at prevailing or negotiated
rates.

In November 1997, Computervision entered into a $47.3 million revolving credit
facility with a lending institution. The credit facility, which replaced all
prior credit facilities, had a term of 18 months and was secured by
substantially all of the assets of Computervision. The weighted average interest
rate on outstanding borrowings was 8.5%. On January 13, 1998, we paid $34.9
million for settlement of the outstanding balance on the revolving credit
facility plus accrued interest and related fees.

The 11 3/8% Senior Subordinate Notes had a maturity date of August 15, 1999 and
accrued interest semi-annually on February 15 and August 15. After August 15,
1997, the notes were redeemable in whole or part at our option at 101.896% of
the principal plus accrued interest through the date of redemption. In February
1998, we paid $188.0 million for redemption of the notes plus accrued interest.

The 8% Convertible Subordinate Debentures, due December 1, 2009, were
convertible into cash at the rate of 33.3% of the principal amount at any time
prior to maturity at the option of the holder. No material conversions occurred
during 1996, 1997, or 1998. The debentures accrued interest semi-annually on
June 1 and December 1. In February 1998, we paid $49.4 million for settlement in
full of the debentures plus accrued interest.


H. COMMITMENTS AND CONTINGENCIES

LEASING ARRANGEMENTS

We lease office facilities and certain equipment under operating leases expiring
at various dates through fiscal 2014. In addition to rent, certain leases
require us to pay directly for taxes, insurance, maintenance, and other
operating expenses. Rent expense, net of sublease income, was $61.6 million in
1996, $60.0 million in 1997, and $45.0 million in 1998. At September 30, 1998,
our future minimum lease payments under noncancellable operating leases with
remaining terms of one or more years are as follows:

                                                               September 30,

Total minimum lease payments                                      $ 212,083

As a result of Computervision's cost saving initiatives in prior years and our
merger with Computervision, certain leased facilities were considered excess. As
of September 30, 1998, the excess facility obligations were $41.9 million.


LEGAL PROCEEDINGS

Certain class action lawsuits have been filed against us and certain of our
current and former officers and directors claiming violations of the federal
securities laws based on alleged misrepresentations regarding our anticipated
revenue and earnings for the third quarter of 1998. We believe the claims are
without merit and we intend to defend them vigorously. We cannot predict the
ultimate resolution of these actions at this time, and there can be no assurance
that the litigation will not have a material adverse impact on our financial
condition or results of operations.

We are also subject to various legal proceedings and claims that arise in the
ordinary course of business. We currently believe that resolving these matters
will not have a material adverse impact on our consolidated financial
statements.


I. STOCKHOLDERS' EQUITY

PREFERRED STOCK

We may issue up to 5.0 million shares of our preferred stock in one or more
series. Our Board of Directors is authorized to fix the rights and terms for
each such series without additional shareholder approval. As of September 30,
1997 and 1998, there were no outstanding shares of preferred stock.


COMMON STOCK

Our Articles of  Organization  authorize us to issue up to 350 million  shares
of our common stock.  Shares of common stock  outstanding  are shown below.

                                                                  September 30,

- -------------------------------------------------------------------------------

On February 8, 1996 and on February 12, 1998, our Board of Directors declared a
one-for-one stock dividend on our common stock to all stockholders of record on
February 22, 1996 and February 27, 1998, respectively. Our financial statements
and notes have been retroactively adjusted to reflect both stock dividends.

In September 1997, our Board of Directors authorized an increase in the number
of shares available for repurchase from 6.0 million to 12.0 million. During 1996
we repurchased 3.6 million shares at a cost of $66.6 million. During 1997, we
repurchased 7.4 million shares at a cost of $184.8 million. Treasury stock
repurchases were suspended during a portion of 1998 in connection with the
Computervision merger. In September 1998, our Board of Directors authorized a
new plan that allows us to repurchase up to 20.0 million shares of our common
stock. In the fourth quarter of 1998, we repurchased 4.7 million shares at a
cost of $50.0 million. The repurchased shares will be used to issue shares for
stock option exercises, employee stock purchase plans, and potential
acquisitions.


J. STOCK PLANS

EMPLOYEE STOCK PURCHASE PLAN

We offer an employee stock purchase plan for all eligible employees. Under the
plan, up to 4.0 million shares of our common stock may be purchased at 85% of
the lower of the fair market value of the stock on the first or the last day of
each six-month offering period. Each employee may elect to have up to 10% of his
or her base pay withheld and applied toward the purchase of shares in such
offering, up to a maximum of ten thousand dollars withheld in any year. During
1996, 1997, and 1998, employees purchased 339,000, 353,000, and 677,000 shares
at average prices of $14.45, $18.41, and $11.36. At September 30, 1998, we had
reserved 1.2 million shares for issuance under this plan.


STOCK OPTION PLANS

We have stock option plans for employees, directors, officers, and consultants
that provide for issuance of nonqualified and incentive stock options. The
option exercise price is typically the fair market value at the date of grant.
These options generally vest over four years and expire ten years from the date
of grant. As of September 30, 1998, 4.5 million options were available for grant
and 53.4 million shares of common stock were reserved for future issuance under
stock option plans.

In conjunction with the Computervision merger on January 12, 1998, we reserved
1.6 million shares of our common stock for outstanding Computervision options
assumed. These assumed options were granted at prices equal to the fair market
value at the date of grant, become exercisable generally in annual installments
over four to five years, and expire ten years from the date of grant.

In July 1998, our Board of Directors approved a one-for-one stock option
exchange program that provided employees the opportunity to exchange stock
options previously granted for new options with a current market price and new
vesting period. Executive officers and directors were not eligible to
participate in the program. The new options were priced at $13.63 based on the
closing price of our common stock as reported by Nasdaq on August 3, 1998, vest
in equal installments over four years from the August 3, 1998 grant date, and
expire on August 3, 2008. A total of 20.0 million options with exercise prices
ranging from $15.06 to $33.50 per share were exchanged under the program.


                                                                              47

Certain employees have disposed of stock acquired through the exercise of
incentive stock options earlier than the mandatory holding period required for
such options. These dispositions, together with the tax benefits realized from
the exercise of nonqualified stock options, create tax benefits that have been
recorded as increases to additional paid-in capital.

For various price ranges, information for options outstanding and exercisable at
September 30, 1998 was as follows:

VALUATION OF STOCK PLANS

We have not recognized compensation expense in connection with stock option
grants under our plans. However, had compensation expense for stock option and
employee stock purchase plans been determined based on fair value at the grant
dates as prescribed by SFAS No. 123, pro forma net income and earnings per share
would have been:

                                                              September 30,

Pro forma net income                     $126,717      $36,725       $9,824
Pro forma earnings per share:
  Basic                                  $   0.48      $  0.14       $ 0.04

- --------------------------------------------------------------------------------

The pro forma disclosures above include the amortization of the fair value of
all options vested between 1996 and 1998, regardless of the grant date. If only
options granted after 1996 were valued, as prescribed by SFAS No. 123, pro forma
net income and pro forma diluted EPS would have been $148.5 million and $0.55
for 1996, $54.2 million and $0.20 for 1997, and $22.4 million and $0.09 for
1998. The effects on pro forma disclosures of applying SFAS No. 123 are not
necessarily representative of the effects on pro forma disclosures of future
years.

The fair value of options granted has been estimated at the date of grant using
the Black-Scholes option-pricing model, assuming the following weighted-average
assumptions:

                                                             September 30,

- --------------------------------------------------------------------------------
Expected life (years)                      5.0           5.0          6.0
Risk-free interest rates                   6.0%          6.2%         5.6%
Volatility                                  40%           40%          50%
Dividend yield                              --             --          --
- --------------------------------------------------------------------------------

The weighted-average fair value of stock options granted was $8.68 in 1996,
$11.17 in 1997, and $9.95 in 1998. The expected life used for stock purchase
plans was six months. The weighted- average fair value of shares granted under
the stock purchase plan was $4.63 in 1996, $6.13 in 1997, and $7.77 in 1998.

The Black-Scholes option-pricing model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option-valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
our options have characteristics significantly different from those of traded
options, and because changes in the subjective input assumptions can materially
affect the fair value estimate, in the opinion of management, the existing
models do not necessarily provide a reliable measure of the fair value of its
options.

K. EMPLOYEE BENEFIT PLANS

We offer a savings plan (PTC plan) to eligible employees. The plan is intended
to qualify under Section 401(k) of the Internal Revenue Code. Participating
employees may defer up to 15% of their pre-tax salary, but not more than
statutory limits. We contribute 50% of the amount contributed by the employee,
up to a maximum of 10% of the employee's earnings. Our matching contributions
vest at a rate of 25% per year of service. We made matching contributions of
$1.9 million, $2.3 million, and $3.2 million in 1996, 1997, and 1998.

U.S. employees of Computervision who completed one year of service were eligible
to participate in a savings plan (CV plan), which is intended to qualify under
Section 401(k) of the Internal Revenue Code. Computervision's matching
contributions, based on the employee's contributions and length of service, were
$1.9 million for 1996 and $1.5 million for 1997. We will make a matching
contribution to the CV plan for 1998 in the second quarter of fiscal 1999.
Beginning April 1, 1998, participants of the CV plan began contributing to the
PTC plan and no further contributions were made into the CV plan. We will merge
the assets of the CV plan into the PTC plan in the first quarter of fiscal 1999.


L. PENSION PLANS

We maintain a defined benefit pension plan covering certain employees of
Computervision. Benefits are based upon length of service and average
compensation, and generally vest after five years of service. Accrued pension
costs have been included in other liabilities.

U.S. PENSION PLAN

Effective April 1990, the benefits under the U.S. pension plan were frozen
indefinitely. We contribute all amounts deemed necessary on an actuarial basis
to satisfy Internal Revenue Service funding requirements. Based upon the
actuarial valuations, we contributed $4.9 million in 1996, $5.0 million in 1997,
and $3.8 million in 1998. Due to the changes in actuarial assumptions and
underperformance of plan investments, as shown below, we were required to record
a minimum pension liability adjustment of $5.8 million in 1997 and $7.8 million
in 1998. Plan assets consist primarily of money market and pooled fund
investments with several banks.


FOREIGN PENSION PLANS

The accrued international pension cost was actuarially computed using
assumptions applicable to each subsidiary plan and economic environment. We
increased our minimum pension liability related to our foreign plans by $13.0
million in 1998 due to the changes in actuarial assumptions and underperformance
of plan investments, as shown below. Plan assets consist of investments in
equities and guaranteed investment contracts with several insurance companies
and banks.

The following tables present the actuarial assumptions used in accounting for
the pension plans:

We license products to customers worldwide. Our sales and marketing operations
outside the United States are conducted principally through our foreign sales
subsidiaries throughout Europe and the Asia/Pacific region. Intercompany sales
and transfers between geographic areas are accounted for at prices that are
designed to be representative of unaffiliated party transactions. Total export
sales were $130.8 million, $148.5 million, and $115.2 million, in 1996, 1997,
and 1998.


N. SUBSEQUENT EVENT

In October 1998, we acquired all of the outstanding stock of InPart Design, Inc.
(InPart) by issuing 2.4 million shares of common stock. The acquisition will be
accounted for as a purchase. Accordingly, the purchase price will be allocated
to all identifiable assets and liabilities of InPart. We expect to allocate a
portion of the purchase price to purchased in-process R&D that will be written
off as a one-time charge in the first quarter of fiscal 1999. Based upon certain
conditions of the agreement, we may be obligated to issue additional shares in
September 1999. InPart, located in Saratoga, CA, provides a comprehensive
library of standard mechanical parts over the Internet that helps manufacturers
improve product development cycles and reduce component expenses.

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF
PARAMETRIC TECHNOLOGY CORPORATION:


In our opinion, based upon our audits and the report of other auditors, the
accompanying consolidated balance sheets and the related consolidated statements
of income, of stockholders' equity, and of cash flows present fairly, in all
material respects, the financial position of Parametric Technology Corporation
and its subsidiaries at September 30, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 1998, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We did not audit the consolidated financial statements of
Computervision Corporation, which statements reflect total revenue of $477.2
million for the year ended December 31, 1996. Those statements were audited by
other auditors whose report thereon has been furnished to us, and our opinion
expressed herein, insofar as it relates to the amounts included for
Computervision Corporation, is based solely on the report of the other auditors.
We conducted our audits of these statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                       Report of Independent Accountants
                        on Financial Statement Schedule

To the Board of Directors
of Parametric Technology Corporation

Our audits of the consolidated financial statements referred to in our report
dated October 26, 1998 appearing in the 1998 Annual Report to Stockholders of
Parametric Technology Corporation (which report and consolidated financial
statements are incorporated by reference in this Annual Report on Form 10-K) and
the report of other auditors also included an audit of the financial statement
schedule listed in Item 14(a)(2) of this Form 10-K.  In our opinion, based on
our audits and the report of other auditors, this financial statement schedule
presents fairly, in all material respects, the information set forth therein
when read in conjunction with the related consolidated financial statements.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Computervision Corporation:
 
  We have audited the consolidated balance sheet of Computervision Corporation
and subsidiaries as of December 31, 1996 and the related consolidated
statements of income, stockholders' deficit and cash flows for the year ended
December 31, 1996. These consolidated financial statements (not presented
herein) are the responsibility of the Company's management. Our responsibility
is to express an opinion on these consolidated financial statements based on
our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
Computervision Corporation and subsidiaries as of December 31, 1996 and the
results of their operations and their cash flows in the year ended December 31,
1996 in conformity with generally accepted accounting principles.

  Our audit was made for the purpose of forming an opinion on the basic
consolidated financial statements taken as a whole. The schedule listed in Item
14(a)(2) of the filing on Form 10-K of Computervision Corporation for the year
ended December 31, 1996 (not presented herein) is for purposes of complying with
the Securities and Exchange Commission's rules and is not part of the basic
consolidated financial statements. The schedule (not presented herein) has been
subjected to the auditing procedures applied in the audit of the basic
consolidated financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic consolidated financial statements taken as a whole.
