                                    PART I


ITEM 1:   Business

                                    General

Parametric Technology Corporation (the "Company") develops, markets and supports
seven families of integrated software products which automate the design-
through-manufacturing process for the mechanical computer-aided design,
manufacturing and engineering ("CAD/CAM/CAE") industry.  Mechanical CAD/CAM/CAE
is a complex, iterative process encompassing a broad spectrum of distinct
engineering disciplines which is essential to the development of virtually all
manufactured products, ranging from consumer products to jet aircraft.  All
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 design process.  The Company's mechanical CAD/CAM/CAE products offer a
high-performance, fully integrated solution which enables end-users to reduce
the time to market and manufacturing costs for their products and, through the
easy evaluation of multiple design alternatives, to improve product quality.
The Company believes that its Pro/ENGINEER(R) product line offers better
price/performance, greater ease of use, and more complete integration of
multiple engineering disciplines than other available mechanical CAD/CAM/CAE
products.

The Company's Pro/ENGINEER product line is based on an innovative software
architecture that incorporates a unique parametric, feature-based solid modeling
technology. The Company's Pro/ENGINEER software uses a single data structure to
capture changes made in any stage of the design-through-manufacturing process
and to automatically update designs and all engineering deliverables. The single
data structure allows all changes to be propagated automatically throughout the
design and manufacturing process, thus enabling users to integrate multiple
engineering activities in the mechanical design process and conduct them on a
concurrent basis.  In addition, as a result of the data structure of the
Company's products, engineers can create, process, modify and store designs
quickly and easily, in a highly efficient manner.  The Company believes that
although certain competitors offer products which integrate the mechanical
CAD/CAM/CAE process by means of data file transfers of static geometric
expressions of a design, there are no competitive products which offer the
degree of automatic engineering change propagation provided by Pro/ENGINEER
software.

The Company's product line currently consists of its core product, Pro/ENGINEER,
first shipped in January 1988, and 50 modules for use in conjunction with it,
depending on the individual needs of each customer. The modules are grouped in
the following product families: Pro/ENGINEER, a unique, fully associative suite
of mechanical design automation software which includes application-specific
products which address the complete spectrum of product-development activities;
Pro/ACCESS(TM) which enables companies to leverage product information from a
variety of sources in the Pro/ENGINEER environment; Pro/CDRS(TM) (Conceptual
Design and Rendering System) which enables product developers to easily create,
evaluate and modify multiple concept models and supports the seamless
integration of conceptual design into the overall design-through-manufacturing
cycle; Pro/JR.(TM), the entry-level version of the Pro/ENGINEER family, which
enables the design-through-documentation of both machined and common plastic
parts and assemblies for the customer migrating from 2D CAD to the capabilities
of 3D solid modeling; Pro/MANUFACTURING(TM) which completes a single-source
solution to a company's design-through-manufacturing requirements based on
Pro/ENGINEER's associativity between the design and manufacturing disciplines;
Pro/MECHANICA(TM) which enables engineers to model product function in a single
desktop environment and to easily and repeatedly analyze and optimize a product
design throughout the development cycle; and Pro/PDM(TM) which helps users
effectively manage the concurrent engineering environment made possible by
Pro/ENGINEER. The Company offers its product families in various packages of
software modules which provide users flexibility in meeting their design
environment requirements.

The Pro/ENGINEER product line runs on all major UNIX(R) and Microsoft(R)
Windows(R) NT and Windows 95 Workstation Operating System platforms, and is
hardware-independent.  The product is written in C programming language, which
allows for portability from one standard workstation to another.

The Pro/ENGINEER product line primarily competes in the high-end of the
mechanical CAD/CAM/CAE market.

                                 Acquisitions

On April 12, 1995, the Company acquired substantially all of the assets and
specified liabilities of the Conceptual Design and Rendering System ("CDRS")
software business operated by the Design Software Division of Evans & Sutherland
Computer Corporation for a net amount of approximately $33,507,000 in cash,
which was paid by the Company from its existing cash balances. The acquisition
has been accounted for as a purchase.

On August 1, 1995, the Company acquired Rasna Corporation  ("Rasna"), a
developer and marketer of software products for mechanical computer-aided
engineering, by merging it into the Company pursuant to an Agreement and Plan of
Merger dated as of May 30, 1995. Based on the number of shares of Rasna common
stock outstanding at August 1, 1995, the Company issued approximately 3,793,000
shares of common stock and reserved approximately 522,000 shares of its common
stock for outstanding Rasna stock options assumed. The merger was accounted for
as a pooling of interests.

                              Product Development

The mechanical CAD/CAM/CAE industry is characterized by rapid technological
advances.  Accordingly, the Company's future success will depend upon its
ability to enhance its current products and develop and introduce new products
and modules which keep pace with technological developments and address
increasingly sophisticated needs of its customers.  The Company believes that
its technological leadership will be maintained through continued expansion of
the scope of applications of its Pro/ENGINEER product family, expansion of the
functionality set of each of the acquired technologies, and the full integration
of all of the product families.  The Company's ability to develop new products
rapidly is facilitated by the modular structure of its software code, which
enables functional subroutines 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.  The Company intends to focus its
ongoing product development efforts on additional products within the
Pro/ENGINEER product family, including tools for manufacturing and quality
assurance engineers, functionality for balancing the form, fit, and functional
needs of our customers' products, and tools to manage all of the resulting
engineering data. The Company intends to further accelerate these efforts to
provide a completely integrated suite of tools for our customers. There can be
no assurance, however, that the Company will be successful in developing and
marketing product enhancements or new products and modules that respond to
technological changes by others, or that its new products will adequately
address the needs of the marketplace.

The Company's practice has been to issue two major releases of its product line
per year, each of which has generally included several new modules.  In
connection with each release, the Company works closely with its customers to
define improvements and enhancements, which are then integrated into the
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, the Company's Cooperative Software Program
("CSP") provides the mechanisms and environment to facilitate the integration of
complementary products with the Pro/ENGINEER product line.  Through the
Company's open software toolkit, the CSP members can build tightly integrated
solutions that satisfy various requirements of the Company's customers.

As of September 30, 1995, the Company's product development was performed by 340
employees at its Waltham, Massachusetts, headquarters; its San Jose, California
and Salt Lake City, Utah offices; and abroad.  The development group includes
experts in mechanical engineering, advanced mathematical techniques, database
structures and operating systems technology.

During the years ended September 30, 1995, 1994 and 1993, the Company incurred
expenses of $25,591,000, $19,882,000 and $14,633,000, respectively, on research
and development.  Software development costs of $1,132,000 (excluding $3,400,000
of purchased software from CDRS) in fiscal 1995, $912,000 in fiscal 1994 and
$619,000 in fiscal 1993 have been capitalized in accordance with Statement of
Financial Accounting Standards No. 86, "Accounting for the Costs of Computer
Software to be Sold, Leased, or Otherwise Marketed."

                                     Sales

The Company focuses its marketing and sales efforts primarily on the
electronics, aerospace, automotive, consumer products and telecommunications
industries.  The Company believes that the broadest possible market can best be
addressed through a multi-channel distribution network.  The Company derives
more than 85% of its revenue from 

                                       3

<PAGE>
 
products distributed directly to its customers and the remainder through value-
added resellers. The Company's sales force manages the activities of all
distribution channels within a geographic area and earns commissions on revenue
from all channels. The Company believes that this mix of distribution channels
addresses the differing sales and support needs of a broad customer base.

As of September 30, 1995, the Company's sales and marketing organization
consisted of 521 people in the United States and 577 people abroad.  The Company
has sales and/or support offices located in 68 cities across the United States
and in 70 cities in 23 foreign countries.

Since inception, the Company has licensed software products for approximately
49,000 seats to nearly 8,200 companies.  A seat of software generally consists
of the Company's core product, Pro/ENGINEER, together with several other
software modules, configured to serve the needs of a single end-user.  End-users
of the Company's products range from small companies to some of the world's
largest manufacturing organizations.  No single customer accounted for more than
10% of the Company's revenue in fiscal 1995.

Information with respect to foreign and domestic operations and export sales may
be found in Note M to the Consolidated Financial Statements of the Annual Report
to Stockholders for the fiscal year ended September 30, 1995 ("1995 Annual
Report to Stockholders"), which is filed as Exhibit 13.1 to this Annual Report
on Form 10-K and incorporated herein by reference.

                                  Competition

The mechanical CAD/CAM/CAE industry is highly competitive, and is characterized
by rapidly advancing technology.  In order to maintain or improve its position
in this industry, the Company must continue to enhance its current products and
develop, in a timely fashion, new products which address the rapidly changing
needs of the marketplace.

The Company competes most directly with the CADAM(R) and CATIA(R) products
marketed by IBM(R), the CADDS(R) product marketed by Computervision Corporation,
the UNIGRAPHICS(R) product marketed by EDS, the I/EMS(TM) product marketed by
Intergraph Corporation and the I-DEAS Master Series(TM) product marketed by
Structural Dynamics Research Corporation.   The Company's future success will
depend in a large part on its ability to further penetrate its installed
customer base as well as the installed customer bases of traditional mechanical
CAD/CAM/CAE suppliers. No assurance can be given that the Company will be able
to compete successfully against current and future sources of competition or
that competitive pressures faced by the Company will not adversely affect its
profitability or financial performance.

The Company believes that the principal bases for competition in its markets are
product functionality, price/performance characteristics, product portability,
ease of product use, sales and marketing strength, support services and
corporate reputation.  In addition, the Company is aware of ongoing efforts by
competitors to emulate the performance and functionality of the Company's
products, and there can be no assurance that competitors will not develop
technology equivalent or superior to that of the Company.

                              Proprietary Rights

The Company's success is dependent upon its proprietary software technology.
The Company relies on a combination of contracts and copyright and trade secret
laws to establish and protect its proprietary rights in its technology.  The
Company distributes its products under software license agreements, which grant
customers perpetual licenses to, rather than ownership of, the Company's
products and which contain various provisions protecting the Company's ownership
of and the confidentiality of the underlying technology.  The Company also
limits access to and distribution of its software, documentation and other
proprietary information.  The source code of the Company's products is protected
as a trade secret and as an unpublished copyright work.  Despite these
precautions, it may be possible to copy or otherwise obtain and use the
Company's products or technology without authorization.  In addition, effective
copyright and trade secret protection may be unavailable or limited in certain
foreign countries.

The Company believes that, due to the rapid pace of innovation within its
industry, factors such as the technological and creative skills of its personnel
are more important to establishing and maintaining a technology leadership
position within the industry than are the various legal protections surrounding
its technology.  The Company believes that its 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.

Pro/ENGINEER, the PTC logo and the "Pro/" family of marks are registered
trademarks or trademarks of the Company in the United States and in foreign
countries.

                                    Backlog

The Company generally ships its products within 30 days after acceptance of a
customer purchase order and execution of a software license agreement.
Accordingly, the Company does not believe that its backlog at any particular
point in time is indicative of future sales levels.

                                   Employees

The Company's success depends upon its ability to attract and retain highly
skilled technical, managerial and sales personnel.  Competition for such
personnel in the computer industry in general, and the mechanical CAD/CAM/CAE
industry in particular, is intense.  Although the Company has not experienced
any significant difficulty to date in attracting and retaining skilled
personnel, there can be no assurance that the Company will be successful in
attracting and retaining the personnel it requires to continue to grow and
operate profitably, both domestically and internationally.

As of September 30, 1995, the Company had 1,960 employees, including 1,098 in
sales, marketing and support activities; 338 in customer support, training and
consulting; 184 in management, finance and administration; and 340 in product
development.  Of these employees, 1,151 were located in the United States and
809 were located in foreign countries.


I
TEM 2:   Properties

The Company's executive offices are located in approximately 251,000 square feet
of office space in Waltham, Massachusetts.  This space, which is also used for
sales and research and development, is leased for an annual rent of
approximately $4,960,000.  The Company also leases 139 additional sales and/or
support offices and development offices in the United States and, through its
wholly-owned subsidiaries, abroad.  The Company believes that its facilities are
adequate for its present needs, but will continue to evaluate the need for
additional space as the growth of the business requires.

<PAGE>
 
          13   Stock shall mean the common stock, $.01 par value, of the
               -----                                                    
     Company.

     2.   Purpose.  This Incentive Stock Option Plan is intended to encourage
          -------                                                            
ownership of the Stock by key employees of the Company and of its subsidiaries
and to provide additional incentive for them to promote the growth, development
and financial success of the Company's business.  This Plan is intended to be an
incentive stock option plan, and the Company may grant pursuant to this Plan
either Incentive Stock Options or Options which do not qualify as Incentive
Stock Options.

     3.   Term of the Plan.  Options under this Plan may be granted on or after
          ----------------                                                     
the date this Plan is approved by the stockholders of the Company; but no Option
under this Plan may be granted more than ten years from the earlier of (a) the
date this Plan is adopted by the Board, and (b) the date this Plan is approved
by the stockholders of the Company.

     4.   Stock Subject to the Plan.  Subject to adjustment as provided in
          -------------------------                                       
Section 14 of this Plan, at no time shall the sum of (i) the number of shares of
the Stock then outstanding which are attributable to the exercise of Options
granted under this Plan, and (ii) the number of shares of the Stock then
issuable upon exercise of outstanding Options granted under this Plan exceed
21,396,000 shares. Shares to be issued upon the exercise of Options granted
under this Plan may be either authorized but unissued or shares held by the
Company in its treasury. If any Option expires or terminates for any reason
without having been exercised in full, the shares not purchased thereunder shall
again be available for Options thereafter to be granted under this Plan.

     5.   Administration.  This Plan shall be administered by the Board or by a
          --------------                                                       
duly appointed committee of the Board having such powers as shall be specified
by the Board; provided, however, that any grants of Options under this Plan to
              --------  -------                                               
an officer (as defined in Section 16, and the rules promulgated thereunder
("Section 16"), of the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) or director of the Company shall be made by the Officers' Stock
Option Committee which shall, in accordance with Section 16 of the Exchange Act,
consist of "disinterested" members of the Board.  Subsequent references herein
to the Board shall also refer to such committees, as appropriate, if they have
been appointed.  No member of the Board shall act upon any matter exclusively
affecting any Option granted or to be granted to himself or herself under this
Plan.  Subject to the provisions of this Plan, the Board shall have complete
authority, in its discretion, to make the following determinations with respect
to each Option to be granted by the Company: (a) the key employee to receive the
Option; (b) the time of granting the Option; (c) the number of shares subject
thereto; (d) the Option Price; and (e) the Option period.  In making such
determinations, the Board may take into account the nature of the services
rendered by the respective employees, their present and potential contributions
to the success of the Company and its subsidiaries, and such other factors as
the Board, in its discretion, shall deem relevant. Subject to the provisions of
this Plan, the Board shall also have complete authority to interpret this Plan,
to prescribe, amend and rescind rules and regulations for the administration of
this Plan, to determine the terms and provisions of the respective Option
Agreements (which need not be identical), to decide all 

                                      -2-

<PAGE>
 
questions and settle all controversies and disputes which may arise in
connection with this Plan, and to make all other determinations necessary or
advisable for the administration of this Plan. The Board's determinations on the
matters referred to in this Section 5 shall be conclusive and binding on all
persons concerned.

     6.   Eligibility.  An Option may be granted only to a key employee of any
          -----------                                                         
one or more of the Company and its subsidiaries. A director of any one or more
of the Company and its subsidiaries who is not also an employee of any one or
more of the Company and its subsidiaries shall not be eligible to receive an
Option.  An Optionee may hold more than one Option, but only on the terms and
subject to the conditions and restrictions herein set forth.  No Optionee may
receive an Option grant which would result in such Optionee having received,
during the fiscal year of the Company in which the grant is proposed to be made,
Options for more than an aggregate of 1,000,000 shares of Stock.

     7.   Time of Granting Options.  The granting of an Option shall take place
          ------------------------                                             
at the time specified by the Board.  Only if expressly so provided by the Board
shall the Grant Date be the date on which an Option Agreement shall have been
duly executed and delivered by the Company and the Optionee.

     8.   Option Price.  The Option Price under each Option shall not be less
          ------------                                                       
than 100 percent of the Fair Market Value of the Stock on the Grant Date;
                                                                         
provided, however, that in the case of an Incentive Stock Option granted to an
- --------  -------                                                             
individual who, on the Grant Date, owns stock possessing more than ten (10%)
percent of the total combined voting power of all classes of stock of the
Company or of a parent or subsidiary corporation of the Company (a "10%
Stockholder"), the Option Price shall not be less than 110 percent of the Fair
Market Value of the Stock on such Grant Date.  The Fair Market Value of the
Stock at the time any Option is granted shall be determined by the Board after
considering all relevant information.  In making any such determination, the
Board shall act in good faith so as to ensure that the Option Price is not less
than 100 percent (or 110 percent, if required) of such Fair Market Value.

     9.   Option Period.  Each Option shall be exercisable at such time or
          -------------                                                   
times, whether or not in installments (which may be cumulative or non-
cumulative), as the Board may determine; and, in the case of an Option made
exercisable in installments, the Board may later determine to accelerate the
time by which any one or more of such installments may be exercised.
Notwithstanding the foregoing, no Option may be exercised after the expiration
of (i) ten years from the date such Option is granted, or (ii) five years from
the date such Option is granted, in the case of an Incentive Stock Option
granted to an individual who, on the Grant Date, is a 10% Stockholder.

     10.  Special Limitation on Exercise.  Notwithstanding anything to the
          ------------------------------                                  
contrary contained in this Plan the aggregate fair market value of the shares of
Stock with respect to which Incentive Stock Options granted under this Plan or
under any other incentive stock option plan of the Company or of a parent or
subsidiary corporation of the Company are exercisable for the first time by any
employee during any calendar year shall not exceed 

                                      -3-

<PAGE>
 
$100,000. For purposes of this Section 10, the fair market value of the shares
of Stock for which any such Incentive Stock Option is granted shall be
determined as of the time of the granting of such Incentive Stock Option.

     11.  Exercise of Option; Investment Purpose.  Each exercise of an Option
          --------------------------------------                             
hereunder may be effected only giving written notice, in the manner provided in
Section 19 hereof, of intent to exercise the Option, specifying the number of
shares as to which the Option is being exercised, and accompanied by full
payment of the Option Price for the number of shares then being acquired. Such
payment shall be made in cash, by certified or bank check payable to the order
of the Company, credit to the Company's account at a financial or brokerage
institution on the date of exercise, or, if the Option so provides, (i) in
shares of the Stock having an aggregate Fair Market Value, at the time of such
payment, equal to the total Option Price for the number of shares of the Stock
for which payment is then being made, or (ii) partly in cash or by certified or
bank check payable to the order of the Company and the balance in shares of the
Stock having an aggregate Fair Market Value, at the time of such payment, equal
to the difference between the total Option Price for the number of shares of the
Stock for which payment is then being made and the amount of the payment in cash
or by certified or bank check; provided, however, that no part of the purchase
                               --------  -------                              
price for any shares of the Stock being purchased pursuant to an exercise of an
Option shall be paid in shares of the Stock which were previously acquired by
the Optionee (x) pursuant to an earlier exercise of such Option, or (y) pursuant
to the exercise of another incentive stock option granted by the Company if the
previously acquired shares have been held by the Optionee for less than two
years since the date of the granting of such other option to him or for less
than one year since the transfer to him of such previously acquired shares.  The
determination of such aggregate Fair Market Value shall be made by the Board,
whose determination in this regard shall be final and binding on all concerned.

     Receipt by the Company of such notice and payment shall, for purposes of
this Plan, constitute exercise of the Option or a part thereof. Within twenty
(20) days thereafter, the Company shall deliver or cause to be delivered to the
Optionee a certificate or certificates for the number of shares of the Stock
then being purchased by him. Such shares shall be fully paid and nonassessable.
If any law or applicable regulation of the Securities and Exchange Commission or
other public regulatory authority (including, but not limited to, a stock
exchange) shall require the Company or the Optionee (a) to register or qualify,
under the Securities Act of 1933, as amended, any similar federal statute then
in force or any state law regulating the sale of securities, any Option Shares
with respect to which notice of intent to exercise shall have been delivered to
the Company or (b) to take any other action in connection with such shares
before issuance thereof may be effected, then the delivery of the certificate or
certificates for such shares shall be postponed until completion of the
necessary action, which the Company shall take in good faith and without delay.
All such action shall be taken by the Company at its own expense.

     The Company may require an individual exercising an Option to represent
that his purchase of shares of the Stock pursuant to such exercise is for 
his own account, for 

                                      -4-

<PAGE>
 
investment and without a view to resale or distribution, and that he will not
sell or otherwise dispose of any of such shares except pursuant to (i) an
effective registration statement covering such transaction filed with the
Securities and Exchange Commission and in compliance with all of the applicable
provisions of the Securities Act of 1933, as amended, and the rules and
regulations thereunder, or (ii) an opinion of Company counsel that such
registration is not required.

     12.  Transferability of Options.  Each Option granted hereunder shall not
          --------------------------                                          
be transferable by the Optionee other than by will or the laws of descent and
distribution or, in the case of an officer (as defined in Section 16 of the
Exchange Act) or director of the Company, such other means as may be permitted
by Rule 16b-3 (or any successor provision) under the Exchange Act.  Each Option
granted hereunder may be exercised, during the Optionee's lifetime, only by him
or her.  In addition, Options granted to an officer (as defined in Section 16 of
the Exchange Act) or director of the Company shall not be transferable for a
period of six months following the grant Date.  From and after the death of an
Optionee, each Option held by such Optionee at his death, to the extent then
exercisable, may be exercised prior to its termination by the person(s) to whom
the Optionee's option rights pass by will or by the applicable laws of descent
and distribution.

     13.  Termination of Employment.  In the event that an Optionee's employment
          -------------------------                                             
is terminated for any reason (voluntary or involuntary), each Option then held
by that Optionee shall expire to the extent not previously exercised ten (10)
days after such Optionee's employment is terminated, except that -
                                                     ------ ----  

          (a)    If the Optionee is on military, sick leave or other bona fide
                                                                     ---- ----
     leave of absence (such as temporary employment by the federal government),
     his employment relationship 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 Optionee's right to reemployment is guaranteed either by
     statute or by contract; otherwise, the Optionee's employment will be deemed
     to have terminated on the 91st day of such leave.

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

          (c)    If the Optionee's employment is terminated by reason of his
     death, each Option then held by the Optionee, 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
     Optionee's option rights pass by will or by the applicable laws of descent
     and distribution.

          (d)    If the Optionee's employment is terminated by reason of his
     becoming permanently and totally disabled, each Option then held by the
     Optionee, to the extent 

                                      -5-

<PAGE>
 
     exercisable upon the occurrence of permanent and total disability, may be
     exercised by the Optionee 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
     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.

     14.  Adjustment of Number of Option Shares.  Each Option Agreement shall
          -------------------------------------                              
provide that, in the event of any stock dividend payable in the Stock or any
split-up or contraction in the number of shares of the Stock occurring after the
date of such Agreement and prior to the exercise in full of the Option covered
thereby, the number of shares subject to such Agreement and the price to be paid
for each share subject to such Option shall each be proportionately adjusted.
Each such Agreement shall also provide that, in case of any reclassification or
change of outstanding shares of the Stock occurring after the date of such
Agreement and prior to the exercise in full of the Option covered thereby, the
number and kind of shares of Stock subject to such Agreement and the price to be
paid for each share subject to such Option shall each be appropriately adjusted.

     Each Option Agreement shall further provide that, in the event of any
reorganization, consolidation or merger to which the Company is a party and in
which the Company does not survive, or upon the dissolution or liquidation of
the Company, the Option covered thereby shall terminate; provided, however, that

(i) in the event of the liquidation or dissolution of the Company, or in the
event of any such reorganization, consolidation or merger in which the Company

such Option shall be exercisable in full, without regard to any installment
restrictions on exercise imposed pursuant to this Plan or such Option Agreement
(but subject to Section 10 hereof), during such period preceding the effective
date of such liquidation, dissolution, reorganization, consolidation or merger
(unless such Option is terminated earlier by its terms) as may be specified by
the Board; and (ii) in the event of any such reorganization, consolidation or
merger, the Board may, in its good faith discretion, arrange to have the
resulting or surviving corporation assume such Option or issue a substitute
option therefor.

     No fraction of a share shall be purchasable or deliverable upon exercise of
an Option, but, in the event any adjustment hereunder of the number of shares
covered by the Option shall cause such number to include a fraction of a share,
such fraction shall be adjusted to the nearest smaller whole number of shares.

     In the event of changes in the outstanding Stock by reason of any stock
dividend, split-up, contraction, reclassification, or change of outstanding
shares of the Stock of the nature

such number of shares of the Stock as will be sufficient to satisfy the
requirements of this Plan and shall pay all fees and expenses necessarily

shall be made for dividends (ordinary or extraordinary, and whether in cash,
securities or other property) or distributions or other rights for which the
record date is prior to the date such certificate is issued, except as provided
in Section 14.

pursuant to Section 14), materially increase the benefits accruing to
participants in the Plan or make any change in the designation of the employees
or class of employees eligible to receive Options under this Plan without the
approval of the stockholders of the Company; (b) impair the rights or increase
the obligations of any Optionee under any Option theretofore granted under this
Plan without the written consent of such Optionee; or (c) cause any Option at
any time granted under this Plan to fail to qualify as an incentive stock option
under Section 422A of the Code.

                       PARAMETRIC TECHNOLOGY CORPORATION
                       1991 EMPLOYEE STOCK PURCHASE PLAN

                   (as adopted by the Board of Directors on
                November 21, 1990, approved by the stockholders
           on February 27, 1991, and amended to reflect one-for-two,
                          one-for-one and one-for-one
                  stock dividends effective on June 27, 1991,
            February 25, 1992 and February 25, 1993, respectively,
          amended by the Board of Directors on November 17, 1994, and
               approved by the stockholders on February 9, 1995


1.     Purposes.
       --------

       The 1991 Employee Stock Purchase Plan of Parametric Technology
Corporation (the "Plan") is intended to provide a method whereby employees of
Parametric Technology Corporation and participating subsidiaries (hereinafter
collectively referred to, unless the context otherwise requires, as the
"Company") will have an opportunity to acquire a proprietary interest in the
Company through the purchase of shares of the common stock, $.01 par value per
share, of the Company ("Common Stock"). It is the intention of the Company to
have the Plan qualify as an "employee stock purchase plan" under Section 423 of
the Internal Revenue Code of 1986, as amended (the "Code"). The provisions of
the Plan shall, accordingly, be construed so as to extend and limit
participation
 in a manner consistent with the requirements of Section 423 of the
Code. However, unless specified in the Code, the fact that an employee is not a
resident of the United States and therefore may not receive the tax benefits
under the Code will not bar such employee from participation in the Plan.

2.     Definitions.
       ----------- 

       (a)     "Coordinator" means the officer of the Company or other person
charged with day-to-day supervision of the Plan as appointed from time to time
by the Board of Directors of the Company (the "Board of Directors"). The Manager
of Human Resources of the Company shall be the initial Coordinator. Notice of
any change in such Coordinator shall be given to all employees eligible under
the Plan.

       (b)     "Base Pay" means regular straight-time earnings (as the same may
be adjusted from time to time), excluding payments for commissions, overtime,
shift differentials, incentive compensation, bonuses and other special payments.
Disability insurance payments shall not be included in Base Pay for purposes of
the Plan

       (c)     "employee" means any person who is customarily employed for 20 or
more hours per week and more than five months in a calendar year by the Company
or by a participating subsidiary.

Offering under the Plan terminates pursuant to Paragraph 4.

       (f)     "Participating subsidiary" means any present or future
corporation which (i) is a "subsidiary corporation" as that term is defined in
Section 425 of the Code and (ii) is designated as a participant in the Plan by

after the grant, such employee would own stock, and/or hold outstanding options
to purchase stock, possessing 5% or more of the total combined voting power or
value of all classes of stock of the Company or of any subsidiary (for purposes
of this subparagraph the rules of Section 425(d) of the Code shall apply in
determining stock ownership of any employee and the term subsidiary shall be as

       (c)     Any provision of the Plan or any other employee stock purchase

stock purchase plans of the Company exceeds $25,000.

4.     Offering Dates.

       The Plan will be implemented by seventeen (17) six-month offerings, one

5.     Participation.
       ------------- 

       (a)     An eligible employee may become a participant in the Plan by
completing an authorization for a payroll deduction ("Authorization") on the
form provided by the Company and filing the Authorization with the Company at
least 15 days and no more than 30 days prior to the applicable Offering
Commencement Date immediately preceding such eligible employee's initial
participation in the Plan.  Such Authorization shall remain in effect until the
participant files a new Authorization with the Company terminating his or her
participation or otherwise amending the most recent Authorization by filing a
new Authorization with the Company at least 15 days but no more than 30 days
prior to the next Offering Commencement Date.

       (b)     Payroll deductions for a participant shall commence with the
first payday on or after the applicable Offering Commencement Date of the
Offering for which such participant's Authorization is filed and shall end with
the final payday on or before the Offering Termination Date of such Offering,
unless sooner terminated pursuant to Paragraph 10.

6.     Payroll Deductions.
       ------------------ 

       (a)     At the time a participant files his or her Authorization, the
participant shall elect to have deductions made for his or her Base Pay on each
payday during the time he or she is a participant in an Offering at the rate of
1, 2, 3, 4, 5, 6, 7, 8, 9 or 10% of his or her Base Pay in effect on the
applicable Offering Commencement Date.  Notwithstanding the foregoing, the
participant's participation in any one or combination of Offerings under the
Plan, shall not exceed, in any fiscal year, an aggregate of the lesser of (i)
$10,000 or (ii) 10% of the participant's Base Pay.

       (b)     All payroll deductions made for a participant shall be credited
to his or her account maintained by the Company under the Plan. A participant
may not make any separate cash payment into such account.

       (c)     Except as provided in Paragraph 10, a participant may not make
any changes to his or her participation during an Offering and, specifically, a
participant may not during an Offering alter the percentage of his or her Base
Pay deducted and credited to his or her account under the Plan. However, if the
Base Pay of the participating employee increases or decreases during the period
of an Offering, the dollar amount of his or her payroll deductions will increase
or decrease accordingly.

7.     Granting of Option.
       ------------------ 

       (a)     Subject to Paragraph 3, for each of the Offerings, a
participating employee shall be deemed to have been granted, on the applicable
Offering Commencement Date, an Option to purchase, on the applicable Offering
Termination Date, a maximum number of shares of Common Stock equal to an amount
determined by (i) multiplying the employee's annualized base pay as of the
Offering Commencement Date by the percentage of such base pay which he or she
has elected to have withheld (but not in any case in excess of 10%); (ii)
dividing such product by 85% of the fair market value of a share of the Common
Stock on the applicable Offering Commencement Date; and (iii) multiplying such
quotient by 1.25. For all purposes of the Plan, the fair market value of the
Common Stock shall be determined as provided in clause (i) of subparagraph (b)
below. For purposes of this paragraph (a), "Annualized Base Pay" shall mean Base
Pay on an annualized basis, determined as follows: (i) in the case of a full-
time employee normally paid on an hourly rate, by multiplying his or her normal
hourly rate by 2080, (ii) in the case of a part-time employee normally paid on
an hourly rate, by multiplying his or her normal hourly rate by the product of
52 times the number of hours in his or her normal work week, (iii) in the case
of an employee normally paid at a bi-weekly rate, by multiplying his or her
normal bi-weekly rate by 26, (iv) in the case of an employee normally paid at a
weekly rate, by multiplying his or her normal weekly rate by 52, and (v) in the
case of an employee normally paid at a monthly rate, by multiplying his or her
normal monthly rate by 12.

       (b)     The purchase price per share of Common Stock purchased during
each Offering (the "Option Exercise Price") shall be the lower of:

               (i)    85% of the last sale price of the Common Stock on the
               NASDAQ National Market System or, if the Common Stock is listed
               on a national securities exchange, 85% of the closing price of
               the Common Stock on such exchange, on the applicable Offering
               Commencement Date (or on the next regular business day on which
               shares of Common Stock shall be traded if no shares of Common
               Stock shall have been traded on such Offering Commencement Date),
               as reported in The Wall Street Journal; or
                              ----------------------- 
          

               (ii)   85% of the last sale price of Common Stock on the NASDAQ
               National Market System or, if the Common Stock is listed on a
               national securities exchange, 85% of the closing price of the
               Common Stock on such exchange, on the applicable Offering
               Termination Date (or on the next regular business day on which
               shares of Common Stock shall be traded if no shares of Common
               Stock shall have been traded on such Offering Termination Date),
               as reported in The Wall Street Journal.
                              ----------------------- 

8.     Exercise of Option.

<PAGE>
 
       With respect to each Offering during the term of the Plan:

       (a)     Unless a participant has given written notice of withdrawal to
the Company as provided in Paragraph 10, his or her Option will be deemed to
have been exercised automatically on the Offering Termination Date applicable to
such Offering, for the purchase of the number of full shares of Common Stock
which the accumulated payroll deductions (without interest) in his or her
account maintained by the Company under the Plan at that time will purchase at
the applicable Option Exercise Price (provided that (i) such number of shares
may be reduced pursuant to Paragraph 12 in the event the Offering is
oversubscribed and (ii) such number of shares may not exceed the number of
shares covered by the Option granted to the participant pursuant to Paragraph
7(a)), and any excess in his or her account at that time will be returned to him
or her without interest promptly following the termination of the Offering.

       (b)     Fractional shares will not be issued under the Plan and any
accumulated payroll deductions which would have been used to purchase fractional
shares shall be returned (without interest) to a participant promptly following
the termination of the Offering.

9.     Delivery.
       -------- 

       As promptly as practicable after the Offering Termination Date of each
Offering, the Company will deliver to each participant a certificate
representing the shares of Common Stock purchased upon the exercise of such
participant's Option.

10.    Withdrawal.
       ---------- 

       (a)     A participant may elect to withdraw all, but not less than all,
payroll deductions credited to his or her account with the Company under any
Offering at any time prior to the applicable Offering Termination Date by giving
written notice of withdrawal to the Coordinator.  All of the participant's
payroll deductions credited to his or her account will be paid to the
participant (without interest) promptly after receipt of such notice of
withdrawal and no further payroll deductions will be made from his or her pay
during such Offering.  The Company may, at its option, treat any attempt by a
participant to borrow on the security of accumulated payroll deductions as an
election, under this Paragraph, to withdraw such deductions.

       (b)     A participant's withdrawal from any Offering will not have any
effect upon his or her eligibility to participate in any succeeding Offering or
in any similar plan which may hereafter be adopted by the Company; provided,
                                                                   --------
however, that an officer (as defined in Section 16, and the rules promulgated
- -------
thereunder ("Section 16"), of the Securities Exchange Act of 1934, as amended
(the "Exchange Act")) or director of the Company who terminates his or her
participation in the Plan prior to the end of any Offering may not participate
in the next Offering under the Plan.

       (c)     Upon termination of the participant's employment for any reason,
including retirement but excluding death or disability (as defined in Section
22(e)(3) of the Code) while in the employ of the Company, such participant will
be deemed to have withdrawn from participation in the pending Offering, and the
payroll deductions credited to his or her account will be returned to the
participant (without interest), or, in the case of his or her death subsequent
to the termination of employment, to the person or persons entitled thereto
under Paragraph 14.

       (d)     Upon termination of the participant's employment because of
disability or death, the participant or his or her beneficiary (as defined in
Paragraph 14) shall have the right to elect, by written notice given to the
Coordinator prior to the expiration of the period of 30 days commencing with the
date of the disability or death of the participant, either

               (i)    to withdraw all of the payroll deductions credited to the
               participant's account under the Plan (without interest); or

               (ii)   to exercise the participant's Option on the applicable
               Offering Termination Date for the purchase of the number of full
               shares of Common Stock which the accumulated payroll deductions
               (without interest) in the participant's account at the date of
               the participant's disability or death will purchase at the
               applicable Option Exercise Price, and to receive any excess money
               in such account (without interest).

       If no such written notice of election is received by the Coordinator, the
participant or beneficiary shall automatically be deemed to have elected to
withdraw the payroll deductions credited to the participant's account at the
date of the participant's disability or death and the same will be paid promptly
following such 30-day period to the participant or said beneficiary without
interest.

11.    Interest.
       -------- 

       No interest will be paid or allowed on any money paid into the Plan or

Company as provided in Paragraph 17 and subject to adjustment for carry-over
shares from previous Offerings as set forth below, the maximum number of shares
available for sale under the Plan during Offerings I through VIII is as follows:

                                      -7-

<PAGE>
 
               Offering I     -    90,000
               Offering II    -    90,000

               Offering VII   -    60,000

If the total number of shares for which Options are exercised on any Offering
Termination Date in accordance with Paragraph 8 exceeds the maximum number of
shares available for such Offering, the Company shall make a pro rata allocation
(based on the number of shares subject to the Option held by each participant)
of the shares available for delivery and distribution in as nearly a uniform
manner as shall be practicable and as it shall determine to be equitable, and
the balance of payroll deductions credited to the account of each participant
under the Plan shall be returned to him or her (without interest) as promptly as
practicable.  If less than the maximum number of shares available in an Offering
(including any carryover shares from a previous Offering) are purchased during
an Offering, the number not purchased shall be carried over to and made
available in the next subsequent Offering.

       (c)     Subject only to the limit set forth in Paragraph 12(a) above,
there shall be no maximum number of shares available for sale during any of
Offerings IX through XVII. If less than the maximum number of shares available
in Offerings I through VII are purchased during such Offerings, the number not
purchased shall be carried over to and made available for Offerings IX through

Offering Termination Date in accordance with Paragraph 8 (together with all
prior exercises under the Plan during such Offering) exceeds the maximum number
of shares available under the Plan as set forth in Paragraph 12(a) above, the
Company shall make a pro rata allocation (based on the number of shares subject
to the Option held by each participant) of the shares available for delivery and
distribution in as nearly a uniform manner as shall be practicable and as it
shall determine to be equitable, and the balance of payroll deductions credited
to the account of each participant under the Plan shall be returned to him or
her (without interest) as promptly as practicable. In such event, no further
Offerings shall be commenced under the Plan unless and until the Plan is amended
to increase the number of shares set forth in Paragraph 12(a) above.

       (d)     The participant will have no interest in the Common Stock covered

       (e)     Certificates for Common Stock to be delivered to a participant
under the Plan will be registered in the name of the participant, or, if the
participant so directs by written

                                      -8-

notice to the Company prior to the Offering Termination Date applicable thereto,
in the names of the participant and one such other person as may be designated
by the participant, as joint tenants with rights of survivorship, to the extent
permitted by applicable law.

13.    Administration.
       -------------- 

       The Plan shall be administered by the Compensation Committee of the Board
of Directors of the Company (the "Committee"). The Coordinator shall, for
matters  involving the Plan, be an ex officio member of that Committee.  The
                                   ----------                               
interpretation and construction of any provision of the Plan and the adoption of
rules and regulations for administering the Plan shall be made by the Committee,
subject, however, at all times to the final jurisdiction which shall rest in the
Board of Directors.  Determinations made by the Committee and approved by the
Board of Directors with respect to any matter or provision contained in the Plan
shall be final, conclusive and binding upon the Company and upon all
participants, their heirs or legal representatives.  Any rule or regulation
adopted by the Committee shall remain in full force and effect unless and until
altered, amended, or repealed by the Committee or the Board of Directors.  The
Company shall indemnify Committee members, to the fullest extent permitted by
applicable law, for any expenses incurred in defending a civil or criminal
action or proceeding, arising out of such member's actions with respect to
administration of the Plan, in advance of the final disposition of such action
or proceeding, upon receipt of an undertaking by the person indemnified to repay
such payment if such member shall be adjudicated not to have acted in good faith
in the reasonable belief that such member's action was in the best interest of
the Company.

14.    Designation of Beneficiary
       --------------------------

       A participant may file a written designation of a beneficiary who is
to receive any shares of Common Stock and/or cash in the event of the death of
the participant.  Such designation shall be effective as to all future
distributions of cash and securities with respect to the participant's account
under the Plan.  Such designation of beneficiary may be changed by the
participant at any time by written notice to the Coordinator.  Within 30 days
after the participant's death, the beneficiary may, as provided in Paragraph
10(d), elect to exercise the participant's Option when it becomes exercisable on
the Offering Termination Date of the then current Offering.  Upon the death of a
participant and upon receipt by the Company of proof of the identity and
existence at the participant's death of a beneficiary validly designated by the
participant under the Plan, and notice of election of the beneficiary to
exercise the participant's Option, the Company shall deliver such stock and/or
cash to such beneficiary.  In the event of the death of a participant and in the
absence of a beneficiary validly designated under the Plan who is living at the
time of such participant's death, the Company shall deliver such cash to the
executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such cash to the spouse or to any
one or dependents of the participant as the Company may determine.  No
beneficiary shall prior to the death of the participant by whom he has been
designated acquire any interest in the stock or cash credited to the
participant's account maintained by the Company under the Plan.

15.    Transferability.
       --------------- 

       Neither payroll deductions credited to a participant's account nor any
rights with regard to the exercise of an Option or to receive Common Stock under
the Plan may be assigned, transferred, pledged, or otherwise disposed of in any
way by the participant otherwise than by will or the laws of descent and
distribution or, in the case of an officer (as defined in Section 16 of the
Exchange Act) or director of the Company, by such other means as may be
permitted by Rule 16b-3 (or any successor provision) under the Exchange Act.
Any such attempted assignment, transfer, pledge, or other disposition shall be
without effect, except that the Company may treat such act as an election to
withdraw funds in accordance with Paragraph 10.  Notwithstanding anything to the
contrary contained herein, shares of Common Stock acquired under the Plan by an
officer (as defined in Section 16 the Exchange Act) or director of the Company
may not be assigned, transferred, pledged, or otherwise disposed of for at least
six months following the Offering Termination Date of the Offering in which such
shares of Common Stock are acquired.

16.    Use of Funds.
       ------------ 

       All payroll deductions received or held by the Company under this Plan
may be used by the Company for any corporate purpose and the Company shall not
be obligated to segregate such payroll deductions.

                                      -10-

<PAGE>
 
17.    Effect of Changes of Common Stock.
       --------------------------------- 

       In the event of any changes in outstanding shares of Common Stock by
reason of stock dividends, subdivisions, combinations and exchanges of shares,
recapitalizations, and the like, the aggregate number and class of shares
available under the Plan and the Option Exercise Price per share shall be
appropriately adjusted by the Board of Directors of the Company, whose
determination shall be conclusive.  Any such adjustments may provide for the
elimination of any fractional shares which would otherwise become subject to any
Options.

18.    Amendment or Termination.
       ------------------------ 

       The Committee or the Board of Directors may at any time terminate or
amend the Plan, provided that no amendment may be made to the Plan without
approval of the stockholders of the Company if such approval is required in
order to comply with Rule 16b-3 under the Exchange Act and other applicable
securities and tax laws.  If the Board of Directors elects at any time to
terminate the Plan, the payroll deductions credited to each participant's
account will be returned to the participant (without interest) as soon as
practicable after such termination.

19.    Notices.
       ------- 

       All notices or other communications by a participant to the Company
under or in connection with the Plan shall be deemed to have been duly given
when received by the Coordinator.

20.    Merger or Consolidation.
       ----------------------- 

       If the Company shall at any time merge or consolidate with another
corporation and the Company is the surviving entity, the holder of each Option
then outstanding will thereafter be entitled to receive at the next Offering
Termination Date upon the automatic exercise of such Option under Paragraph 8(a)
(unless previously withdrawn pursuant to Paragraph 10) for each share as to
which such Option shall be exercised the securities or property which a holder
of one share of the Common Stock was entitled to upon and at the time of such
merger or consolidation, and the Board of Directors shall take such steps in
connection with such merger or consolidation as the Board of Directors shall
deem necessary to ensure that the provisions of Paragraph 17 shall thereafter be
applicable, as nearly as reasonably may be, to such securities or property.  In
the event of a merger or consolidation in which the Company is not the surviving
entity, or of a sale of substantially all of the assets of the Company, the Plan
shall terminate, and all payroll deductions credited to participants' accounts
shall be returned to them (without interest) provided, however, that the Board
of Directors may, in the event of such merger or sale, accelerate the Offering
Termination Date of the Offering then in effect and permit participants to
purchase shares under the Plan at such accelerated Offering Termination Date.

21.    Registration and Qualification of the Plan under Applicable Securities 
       ----------------------------------------------------------------------
       Laws.
       ----

       No Option shall be granted under the Plan until such time as the Company
has qualified and registered the shares which are subject to the Option under
the applicable state and federal securities laws to the extent required by such 
laws.

                                   Agreement
                                   ---------

     This Agreement is entered into as of this 2nd day of October, 1995 between
Parametric Technology Corporation, a Massachusetts corporation (the "Company"),
and Edwin J. Gillis (the "Officer").

     WHEREAS, the Company desires to employ the Officer as the Senior Vice
President of Finance and Administration, Chief Financial Officer and Treasurer
of the Company; and

     WHEREAS, to provide incentive for the Officer to accept employment with the
Company, the Company desires to make the following arrangements with the Officer
concerning his termination of employment.

     NOW, THEREFORE, the Company and the Officer hereby agree as follows:

     1.  Termination Notice.  The Company agrees that it may not terminate the
         ------------------                                                   
employment of the Officer unless (i) such termination is for Cause (as defined
below) or (ii) the Company has delivered to the Officer a written notice of such
termination (the "Termination Notice") at least six months in advance of the
termination date.  The duties of the Officer during the period from the date of
delivery of a Termination Notice until the termination of his employment shall
be as determined by the Board of Directors.

     2.  Salary.   During the period from the date of delivery of the
         ------                                                      
Termination
 Notice (the "Notice Date") until the earlier of (i) the date six
months after the Notice Date or (ii) the date the Officer commences employment
with another company or organization, the Company shall pay to the Officer a
salary that is equal, on an annualized basis, to the highest annual salary
(excluding any bonuses) in effect with respect to the Officer during the six-
month period immediately preceding the Termination Notice.

     3.  Stock Options.      Effective upon a Change in Control (as defined
         -------------                                                     
below) of the Company, all outstanding stock options under the Company's 1987
Incentive Stock Option Plan then held by the Officer shall become exercisable in
full, notwithstanding any vesting schedule or other provisions to the contrary
in the agreements evidencing such options; and the Company and the Officer
hereby agree that such option agreements are hereby amended to give effect to
this provision.

     4.   Definitions.
          ----------- 

                                       1

<PAGE>
 
          (a)    A termination by the Company of the Officer's employment for
"Cause" shall mean termination (i) for the Officer's willful and continued
failure to substantially perform his duties to the Company (other than any such
failure resulting from the Officer's incapacity due to physical or mental
illness or any such actual or perceived failure after a Change in Status of the
Officer), provided that (a) the Company has delivered a written demand for
substantial performance to the Officer specifically identifying the manner in
which the Company believes that the Officer has not substantially performed his
duties, and (b) the Officer has not cured such failure within 30 days after such
demand, (ii) for willful conduct by the Officer which is demonstrably and
materially injurious to the Company, or (iii) for the Officer's willful
violation of any material provision of any confidentiality, nondisclosure,
assignment of invention, noncompetition or similar agreement entered into by the
Officer in connection with his employment by the Company.  For purposes of this
paragraph, no act or failure to act on the Officer's part shall be deemed
"willful" unless done or omitted to be done by the Officer not in good faith and
without reasonable belief that his action or omission was in the best interests
of the Company.

          (b)    A "Change in Control" of the Company shall mean the occurrence
of any of the following events: (i) any "person", as such term is used in
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") (other than the Company, any trustee or other fiduciary holding
securities under an employee benefit plan of the Company, or any corporation
owned directly or indirectly by the stockholders of the Company in substantially
the same proportion as their ownership of stock in the Company) is or becomes
the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act),
directly or indirectly, of securities of the Company representing 50% or more of
the combined voting power of the Company's then outstanding securities (other
than as a result of acquisitions of such securities from the Company); (ii)
individuals who, as of the date hereof, constitute the Board of Directors of the
Company (the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board, provided that any person becoming a director subsequent
to the date hereof whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board (other than an election or nomination of an
individual

                                       2

<PAGE>
 
whose initial assumption of office is in connection with an actual or threatened
election contest relating to the election of the directors of the Company) shall
be, for purposes of this Agreement, considered to be a member of the Incumbent
Board; (iii) the stockholders of the Company approve a merger or consolidation
of the Company with any other corporation, other than (A) a merger or
consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than 50% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (B) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
"person" (as defined above) acquires more than 20% of the combined voting power
of the Company's then outstanding securities; or (iv) the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company of all or substantially all of the
Company's assets.

     5.   Term.    This Agreement shall continue in effect for a period of three
          ----                                                                  
years from the date hereof, unless extended by the mutual written consent of the
Company and the Officer.

     6.   Successors.
          ---------- 

          (a)    This Agreement is personal to the Officer and without the prior
written consent of the Company shall not be assignable by the Officer otherwise
than by will or the laws of descent and distribution.

          (b)    This Agreement shall inure to the benefit of and be binding
upon the Company and its successors and assigns.

          (c)    The Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used in this Agreement, "Company" shall mean the Company as
defined above and any successor to its business and/or assets as aforesaid which
assumes and agrees to perform this Agreement.

     7.   Miscellaneous.

a written agreement executed by the parties hereto or their respective
successors and legal representatives.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS 
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                       Parametric Technology Corporation

Parametric Technology Corporation is a leading supplier of software tools used
to automate the mechanical development of a product from its conceptual design
through its release into manufacturing. The Company derives its revenue from the
sale and support of software used in the mechanical segment of the CAD/CAM/CAE
(computer-aided design, manufacturing and engineering) industry.

RESULTS OF OPERATIONS
 ................................................................................

The Company's revenue and net income for the fiscal year ended September 30,
1995 increased 47.7% and 44.7%, respectively, over the previous fiscal year,
excluding non-recurring charges in fiscal 1995 of $10,438,000 related to the
merger of Rasna Corporation ("Rasna") into the Company and $19,000,000 related
to its acquisition of the Conceptual Design and Rendering System ("CDRS")
software business from Evans & Sutherland Computer Corporation. Net income as a
percentage of revenue, excluding the non-recurring charges, was 25.0% in fiscal
1995 compared to 25.5% in fiscal 1994 and 24.2% in fiscal 1993. Including the
Rasna and CDRS non-recurring charges, the Company's net income
 as a percentage
of revenue was 19.6% in fiscal 1995. The Rasna merger has been accounted for as
a pooling of interests. Therefore, all financial information contained herein
has been retroactively combined to reflect this transaction. The operating
results of CDRS are included herein since April 12, 1995, the date of the
acquisition.

     The following table sets forth certain consolidated financial data as a
percentage of revenue for the fiscal years ended September 30, 1995, 1994 and
1993.

Revenue

Revenue, including license and service revenues, for fiscal 1995 rose to
$394,310,000, compared with fiscal 1994 revenue of $266,974,000 and fiscal 1993
revenue of $179,311,000. These totals represent increases of 47.7% in 1995 and
48.9% in 1994. The increase in license revenue results from an increase in the
number of seats of software licensed and from a slightly higher price realized
per seat. A seat of software generally consists of the Company's core product,
Pro/ENGINEER/(R)/, together with several other software modules, configured to
serve the needs of a single end-user. The Company licensed approximately 15,900
seats of software in fiscal 1995, 34.7% more than fiscal 1994's 11,800 seats,
which were 22.9% more than fiscal 1993's 9,600 seats. The increase in the number
of seats licensed was achieved as a result of continued market penetration of
the Company's products. The average price per seat during fiscal 1995 was
approximately $18,100, compared with an average price of approximately $17,500
in 1994 and $15,100 in 1993. Service revenue is derived from the sale of
software maintenance contracts and the performance of training and consulting
services. In fiscal 1995, service revenue increased to 26.9% of total revenue
from 22.7% in fiscal 1994 and 19.3% in fiscal 1993. This revenue increased
during both fiscal 1995 and 1994 as a result of the growth in the Company's
installed customer base and increased training and consulting services performed
for those customers. Revenue outside of North America accounted for 49.8%,
43.3% and 33.2% of revenue in fiscal 1995, 1994 and 1993, respectively. These
increases are a result of the Company's continued investment in the
international marketplace. The Company expects that total revenue will increase
in fiscal 1996 from continued penetration in the mechanical CAD/CAM/CAE
industry, and that international revenue will continue to account for a
significant portion of that total growth.

     Consistent with past experience, a high percentage of the Company's
revenues are expected to be realized in the third month of each fiscal quarter
and tend to be concentrated in the latter half of that month. The Company's
orders early in a quarter will not generally be large enough to assure that it
will meet its revenue targets for any particular quarter. Accordingly, the
Company's quarterly results may be difficult to predict until the end of the
quarter, and a shortfall in shipments or contract orders at the end of any
particular quarter may cause the results for that quarter to fall short of
anticipated levels.

Cost of Revenue

Cost of license revenue consists of the amortization of capitalized computer
software costs as well as material and overhead costs associated with compact
disks, packaging and shipping. Cost of service revenue includes the costs
associated with train-

ing, software maintenance and consulting revenues. Combined, these expenses
increased to $36,318,000 in fiscal 1995 from $21,032,000 in fiscal 1994 and
$12,054,000 in fiscal 1993. Total cost of revenue as a percentage of revenue
increased to 9.2% in fiscal 1995 from 7.9% in fiscal 1994 and 6.7% in fiscal
1993. The absolute and percentage increases in total cost of revenue resulted
primarily from growth in staffing necessary to generate and support increased
worldwide service revenue and material costs associated with increased revenue.
Cost of service revenue, which is the largest component of total cost of
revenue, increased 73.5% in fiscal 1995 and 82.9% in fiscal 1994, while
associated revenue increased 74.5% and 75.9%, respectively.

Sales and Marketing

Sales and marketing expenses increased to $163,918,000 in fiscal 1995 from
$107,940,000 in fiscal 1994 and $76,121,000 in fiscal 1993, and increased as a
percentage of revenue to 41.6% from 40.4% in fiscal 1994, but decreased from
42.4% in fiscal 1993. The absolute increases in these expenses during fiscal
1995 and 1994 were due principally to worldwide expansion of the sales force and
sales commissions associated with higher revenue. International sales and
marketing expenses represented 52.1% of total sales and marketing expenses in
fiscal 1995, compared with 44.8% in 1994 and 39.7% in 1993. The Company expects
to continue the growth of its worldwide sales and marketing organization during
future periods, reflecting the Company's commitment to expand its global market
penetration.

Research and Development

The Company continued to make significant investments in research and
development, including the investments in research and development personnel
associated with the acquisition of CDRS and the merger with Rasna. Research and
development expenses increased to $25,591,000 in fiscal 1995 from $19,882,000 in
fiscal 1994 and $14,633,000 in fiscal 1993, while decreasing as a percentage of
revenue to 6.5% from 7.5% and 8.2%, respectively. The absolute increases in
expenses resulted primarily from growth in the research and development staff.

     Software development costs of $1,132,000 (excluding $3,400,000 of purchased
software from CDRS) in fiscal 1995, $912,000 in fiscal 1994 and $619,000 in
fiscal 1993 have been capitalized in accordance with Statement of Financial
Accounting Standards No. 86, "Accounting for the Costs of Computer Software to
be Sold, Leased, or Otherwise Marketed". The amounts capitalized represent 4.2%,
4.4% and 4.1% of total research and development costs during such years.
Capitalized computer software costs are amortized over the economic useful lives
of the related products, typically three years.

General and Administrative

General and administrative expenses include the costs of corporate, finance,
human resources and administrative functions of the Company. These expenses
increased to $20,414,000 in fiscal 1995 from $14,758,000 in fiscal 1994 and
$10,001,000 in fiscal 1993, while decreasing as a percentage of revenue to 5.2%
from 5.5% and 5.6%, respectively. The absolute increases in these expenses were
primarily due to the hiring of additional employees necessary to support the
Company's worldwide growth.

Acquisition and Related Costs

In conjunction with the CDRS acquisition in the third quarter of fiscal 1995,
the Company recorded a non-recurring charge of $19,000,000 related to the write-
off of purchased research and development in process.

     In conjunction with the Rasna merger in the fourth quarter of fiscal 1995,
the Company recorded a non-recurring charge of $10,438,000, which included
approximately $6,028,000 for transaction fees, $1,722,000 for severance related
expenses and $2,688,000 related to integration costs and lease and distributor
termination costs. At September 30, 1995, the Company had accrued $1,446,000 for
future cash outlays and reserved $1,443,000 for non-cash charges associated with
this non-recurring charge.

Other Income, Net

Other income, net, primarily includes interest income and expense and foreign
currency gains and losses. Interest income increased to $10,159,000 in fiscal
1995 from $4,642,000 in fiscal 1994 and $2,895,000 in fiscal 1993 due primarily
to higher interest-bearing cash and short-term investment balances, which
resulted from positive cash flows from operations and proceeds from stock option
exercises.

Foreign Exchange

A growing percentage of the Company's revenue and expenses are transacted in
foreign currencies. As a result, the Company's international results of
operations are subject to foreign exchange fluctuations. The Company enters into
forward exchange contracts to hedge specific foreign currency denominated
receivables to offset a portion of the foreign exchange fluctuations.

Income Taxes

The effective income tax rate was 39.4% in fiscal 1995, 37.4% in fiscal 1994 and
36.9% in fiscal 1993. The difference between the effective and statutory federal
rate was due primarily to the benefit of tax exempt interest income offset by
the impact of state income taxes and, in fiscal 1995, the non-deductible
acquisition costs associated with the Rasna merger. In fiscal 1994, Parametric
adopted the provisions of Statement of

Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"), on a prospective basis. Prior to the adoption of FAS 109, Parametric
accounted for income taxes using Accounting Principles Board Opinion No. 11.
Adoption of FAS 109 by Parametric did not have a material impact on the
Company's consolidated financial statements. Rasna adopted FAS 109 prior to
fiscal 1993. The companies did not conform income tax accounting policies in
connection with the Rasna merger.

LIQUIDITY AND CAPITAL RESOURCES
 ................................................................................

As of September 30, 1995, the Company had $145,638,000 of cash and cash
equivalents and $162,610,000 of short-term investments. Effective October 1,
1994, the Company adopted the provisions of Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities", on a prospective basis. In conjunction with the adoption of this
statement, all cash equivalents and short-term investments have been classified
as available for sale and are reported at fair value with unrealized gains and
losses included in stockholders' equity. Adoption of this statement did not have
a material impact on the Company's consolidated financial statements.

     Net cash provided by operations, consisting primarily of net income from
operations, the non-recurring charge for purchased research and development in
process, the increases in income taxes and deferred revenue, offset by the
increase in accounts receivable, was $119,017,000, $84,452,000 and $48,558,000
for fiscal 1995, 1994 and 1993, respectively.

     Investment activities consisted primarily of purchases and sales of short-
term investments, additions to property and equipment and the acquisition of
CDRS. Net cash used by investing activities totaled $141,270,000 for fiscal
1995, compared with $23,897,000 and $36,740,000 for fiscal 1994 and 1993,
respectively. Net cash provided by financing activities, consisting primarily of
proceeds from issuance of common stock, was $25,354,000, $10,669,000 and
$9,060,000 for fiscal 1995, 1994 and 1993, respectively.

     Due to the Company's strong cash position, the Company allowed a $5,000,000
unsecured demand line of credit with a bank to expire on January 31, 1995. There
were no borrowings under this line during fiscal 1995.

     On May 12, 1994, the Company announced that its Board of Directors had
authorized a plan that would allow the repurchase of its common stock. The plan
authorizes the Company to acquire up to 3,000,000 shares of its common stock
from time to time in the open market or through privately negotiated
transactions. During fiscal 1994, the Company purchased 157,000 shares at a cost
of $4,356,000, all of which were reissued by September 30, 1994 to satisfy stock
option exercises and employee stock purchases under Company plans. The total
amount of cash required in current and future periods to repurchase the full
number of shares authorized but not repurchased would be approximately
$175,000,000 based upon the September 30, 1995 closing stock price. During
fiscal 1996, the Company intends to repurchase shares to partially offset the
dilution caused by the exercise of stock options under the Company's option
plans and the purchase of shares under the employee stock purchase plan. The
Company expects to use available cash and cash generated from operations in
future fiscal periods to fund any such repurchases.

     On April 12, 1995, the Company acquired substantially all of the assets and
specified liabilities of the CDRS software business operated by the Design
Software Division of Evans & Sutherland Computer Corporation for approximately
$33,507,000 in cash, which was paid by the Company from its existing cash
balances. The acquisition has been accounted for as a purchase. The purchase
price has been allocated to the assets acquired, including certain intangible
assets, such as purchased computer software and research and development in
process, based on their respective fair values. The excess of the purchase price
over the estimated fair value of the net assets acquired has been recorded as
goodwill ($7,703,000), which is being amortized on a straight-line basis over
seven years.

     On August 1, 1995, the Company acquired Rasna by merging it into the
Company pursuant to an Agreement and Plan of Merger dated as of May 30, 1995.
Based on the number of shares of Rasna common stock outstanding at August 1,
1995, approximately 3,793,000 shares of the Company's common stock were issued
and approximately 522,000 shares of its common stock were reserved for
outstanding Rasna options assumed. The merger was accounted for as a pooling of
interests.

     The Company believes that existing cash and short-term investment balances
together with cash generated from operations will be sufficient to meet the
Company's working capital, financing and capital expenditure requirements
through at least fiscal 1996.

     Market prices for securities of software companies have generally been
volatile. In particular, the market price of the Company's common stock has been
and may continue to be subject to significant fluctuations. These fluctuations
may be due to factors specific to the Company or to factors affecting the
computer industry or the securities markets in general.

     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("FAS 123"). This statement establishes financial accounting and
reporting standards for stock-based employee compensation plans. While the
Company is reviewing the adoption and impact of FAS 123, it is expected that
this standard will have no impact on the Company's financial position or results
of operations. The Company will be required to adopt FAS 123 in fiscal 1997.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       Parametric Technology Corporation

A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 ................................................................................

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in the financial statements.

     On August 1, 1995, the Company completed its merger with Rasna Corporation
("Rasna"), a developer and marketer of software products for mechanical 
computer-aided engineering. The merger was accounted for as a pooling of
interests. Accordingly, the accompanying consolidated financial statements have
been retroactively combined to reflect this transaction.

     Due to the differing year ends of the Company and Rasna, financial
information for dissimilar fiscal years has been combined. Rasna's results of
operations for its fiscal years ended December 31, 1994 and 1993, were combined
with the Company's results of operations for the fiscal years ended September
30, 1994 and 1993, respectively. Balance sheet information as of September 30,
1994 includes the financial position of Rasna as of December 31, 1994 and the
Company as of September 30, 1994. Accordingly, Rasna's results of operations for
the three months ended December 31, 1994 (including revenue, operating income
and net income of $6,832,000, $548,000 and $404,000, respectively) were
duplicated in the combined statements of income for fiscal 1995 and 1994.
Therefore, Rasna's net income for one of the three month periods ended 
December 31, 1994 was eliminated from stockholders' equity.

Foreign Currency Translation

Foreign currency financial statements of international subsidiaries, where the
local currency is the functional currency, are translated using exchange rates
in effect at period end for assets and liabilities and at average rates during
the period for results of operations. The resulting foreign currency translation
adjustments are reflected as a separate component of stockholders' equity. For
international subsidiaries where the U.S. dollar is the functional currency,
monetary assets and liabilities are translated using exchange rates in effect at
period end, nonmonetary assets and liabilities are translated at historical
rates and results of operations are translated at average rates for the period.
The resulting foreign currency translation adjustments are included in income.
Any gains or losses from foreign exchange transactions are included in income.
Currency losses of $781,000, currency gains of $222,000 and currency losses of
$502,000 were recognized in fiscal 1995, 1994 and 1993, respectively.

Revenue Recognition

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, or as earned for customers with contractual commitments. Revenue from
software maintenance contracts is recognized ratably over the contract period
and other service revenue is recognized upon performance.

Cash Equivalents and Short-term Investments

The Company considers all highly liquid investments purchased with a maturity of
three months or less to be cash equivalents. Short-term investments are those
with maturities in excess of three months but less than one year. Effective
October 1, 1994, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities", on a prospective basis. In conjunction with the adoption of
this statement, all cash equivalents and short-term investments have been
classified as available for sale and are reported at fair value with unrealized
gains and losses included in stockholders' equity. At September 30, 1995, the
cost of cash equivalents and short-term investments equaled market and therefore
no valuation allowance was recorded.

     The Company invests its non-operating cash in debt instruments of financial
institutions, government entities and corporations. The Company has established
guidelines relative to credit ratings, diversification and maturities that
maintain safety and liquidity. The Company has not experienced any losses on its
cash equivalents and short-term investments.

Concentration of Credit Risk

The Company's 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.

Forward Foreign Exchange Contracts

The Company enters into transactions denominated in foreign currencies and
includes the exchange gain or loss arising from such transactions in income. The
Company enters into forward exchange contracts to hedge specific foreign
currency denominated receivables, which require the Company to exchange foreign
currencies for U.S. dollars at maturity at rates agreed to at inception of the
contracts. As of September 30, 1995 and 1994, the Company had approximately
$1,389,000 and $2,540,000, respectively, of foreign exchange contracts
outstanding. Cash flows from the forward exchange contracts are classified with
the related receivables.

Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-
line method over the estimated useful lives, typically three years. Leasehold
improvements are amortized over the shorter of the 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 the estimated useful lives.
Maintenance and repairs are charged to expense when incurred; additions and
improvements are capitalized.

     Upon retirement or sale, the cost of the disposed asset and the related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is credited or charged to income.

Capitalized Computer Software Costs and Intangible Assets

The Company incurs costs to develop 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 years, beginning at their initial shipment
date. Capitalized computer software costs are presented net of accumulated
amortization of $3,651,000 and $2,317,000 at September 30, 1995 and 1994,
respectively. Amortization charged to expense was $1,334,000, $665,000 and
$619,000 for the fiscal years ended September 30, 1995, 1994 and 1993,
respectively.

     Purchased software of $3,400,000 and intangible assets of $11,083,000
(including goodwill of $7,703,000) capitalized in fiscal 1995 were attributable
to the acquisition of the Conceptual Design and Rendering System ("CDRS")
software business operated by the Design Software Division of Evans & Sutherland
Computer Corporation. These assets, included in capitalized computer software
costs and other assets, respectively, are amortized on a straight-line basis,
over three and seven years, respectively. Amortization charges related to
intangible assets, the majority of which were reflected in general and
administrative expenses, totaled $725,000 for the fiscal year ended 
September 30, 1995.

     The Company evaluates the net realizable value of capitalized computer
software costs and intangible assets on an on-going basis relying on a number of
factors including operating results, business plans, budgets and economic
projections.

Income Per Common Share

Income per common share is computed based upon the weighted average number of 
common and dilutive common equivalent shares outstanding during the year. 
Fully diluted and primary earnings per common share are the same amounts for 
each of the years presented. Dilutive common equivalent shares consist of 
stock options (calculated using the treasury stock method).

B. ACQUISITIONS
 ................................................................................

On August 1, 1995, the Company acquired Rasna by merging it into the Company 
pursuant to an Agreement and Plan of Merger dated as of May 30, 1995. Based 
on the number of shares of Rasna common stock outstanding at August 1, 1995, 
the Company issued approximately 3,793,000 shares of common stock and 
reserved approximately 522,000 shares of its common stock for outstanding 
Rasna stock options assumed. The merger was accounted for as a pooling of 
interests.

     In conjunction with the Rasna merger in the fourth quarter of fiscal 1995,
the Company recorded a non-recurring charge of $10,438,000, which included
approximately $6,028,000 for transaction fees, $1,722,000 for severance related
expenses and $2,688,000 related to integration costs and lease and distributor
termination costs. At September 30, 1995, the Company had accrued $1,446,000 for
future cash outlays and reserved $1,443,000 for non-cash charges associated with
this non-recurring charge.

     The following information shows revenue and net income of the separate
companies during the periods preceding the combination. Adjustments recorded to
conform the accounting policies of the companies were not material to the
consolidated financial statements.

     On April 12, 1995, the Company acquired substantially all of the assets and
specified liabilities of CDRS for $33,507,000 in cash, which was paid by the
Company from its existing cash balances. The acquisition has been accounted for
as a purchase. The purchase price has been allocated to the assets acquired,
including certain intangible assets, such as purchased computer software and
research and development in process, based on their respective fair values. The
excess of the purchase price over the estimated fair value of the net assets
acquired has been recorded as goodwill ($7,703,000), which is being amortized on
a straight-line basis over seven years. In conjunction with the acquisition in
the third quarter, the Company recorded a non-recurring charge of $19,000,000
related to the write-off of

purchased research and development in process. CDRS's results of operations have
been included in the consolidated results of operations since the date of
acquisition.

     The following pro forma summary presents the consolidated results of
operations of the Company as if the acquisition of CDRS had occurred as of the
beginning of the periods presented, after giving effect to certain adjustments,
including amortization of goodwill and other intangibles, decreased interest
income related to cash used to finance the acquisition and related income tax
effects. The summary excludes the non-recurring charge of $19,000,000 and
reflects the restatement for Rasna pooling of interests. Pro forma results of
operations for the fiscal year ended September 30, 1995 include CDRS's results
of operations for the period from October 1, 1994 through April 11, 1995. Pro
forma results of operations for the fiscal year ended September 30, 1994 include
CDRS's results of operations for the twelve months ended December 31, 1994.
These pro forma results are not necessarily indicative of those that would have
occurred had the acquisition taken place as of the beginning of the periods
presented.

E. INCOME TAXES
 ................................................................................

In fiscal 1994, Parametric adopted the provisions of the Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS 109"), on a
prospective basis. Prior to the adoption of FAS 109, Parametric accounted for
income taxes using Accounting Principles Board Opinion No. 11. Adoption of FAS
109 by Parametric did not have a material impact on the Company's consolidated
financial statements. Rasna adopted FAS 109 prior to fiscal 1993. The companies
did not conform income tax accounting policies in connection with the Rasna
merger.

     Under FAS 109, deferred tax assets and liabilities are recognized for the
expected future tax consequences, utilizing current tax rates, of temporary
differences between the carrying amounts and the tax bases of assets and
liabilities. Deferred tax assets are recognized, net of any valuation allowance,
for the estimated future tax effects of deductible temporary differences and tax
operating loss and credit carryforwards. Deferred tax expense represents the
change in the deferred tax asset or liability balances.

     The net operating loss carryforwards of $17,534,000 at September 30, 1995
expire between fiscal 1996 and 2007. Ownership changes, as defined in the
Internal Revenue Code of 1986, as amended, limit the amount of the net operating
loss carryforward that can be utilized annually. The foreign tax credit
carryforwards expire between fiscal 1996 and 1999. The research and development
credit carryforwards expire between fiscal 2001 and 2008. The Company has
recorded a valuation allowance for the tax benefit of certain foreign net
operating loss carryforwards since realization of these future benefits is not
sufficiently assured at September 30, 1995.

F. COMMON STOCK
 ................................................................................

On February 4, 1993, the Company's Board of Directors declared a one-for-one
stock dividend on all shares of common stock, which became effective on 
February 25, 1993 to all stockholders of record on February 18, 1993. These
financial statements and related notes have been retroactively adjusted, as
appropriate, to reflect the one-for-one stock dividend.

     On May 12, 1994, the Company announced that its Board of Directors had
authorized a plan that would allow the repurchase of its common stock. The plan
authorizes the Company to acquire up to 3,000,000 shares of its common stock
from time to time in the open market or through privately negotiated
transactions. During fiscal 1996, the Company intends to repurchase shares to
partially offset the dilution caused by the exercise of stock options under the
Company's option plans and the purchase of shares under the employee stock
purchase plan.

     On November 17, 1995, the Board of Directors voted to recommend to the
stockholders the approval of an amendment to the Company's Articles of
Organization to increase the number of authorized shares of the Company's common
stock from 75,000,000 to 215,000,000.

G. STOCK OPTIONS
 ................................................................................

Under the 1987 Incentive Stock Option Plan (the "Stock Option Plan"), the Board
of Directors may grant options to key employees to purchase shares at an option
exercise price equal to the fair market value on the date of grant. The options
are exercisable at such times, in installments or otherwise, as the Board of
Directors may determine. Generally, these options vest ratably over a period of
four years and expire ten years from the date of grant. In fiscal 1994, the
stockholders approved an increase in the number of shares issuable under this
plan from 16,596,000 shares to 18,996,000 shares. In fiscal 1995, the
stockholders approved an increase in the number of

                                      31

<PAGE>
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       Parametric Technology Corporation

shares issuable under the plan from 18,996,000 shares to 21,396,000 shares and
to limit the number of shares that may be granted to any eligible employee under
the Stock Option Plan in any fiscal year to 1,000,000 shares. On November 17,
1995, the Board of Directors approved, subject to stockholder approval, an
increase in the number of shares issuable under this plan from 21,396,000 shares
to 24,396,000 shares and to change the designation of persons eligible to
receive options under the Stock Option Plan to include consultants. The number
of stock options exercisable at September 30, 1995 was 2,123,000.

     Under the 1992 Director Stock Option Plan (the "1992 Director Plan"),
320,000 shares of common stock have been reserved. The purpose of the 1992
Director Plan is to attract and retain qualified persons who are not also
officers or employees of the Company (the "Eligible Directors") to serve as
directors of the Company and to encourage stock ownership in the Company by such
directors.

     Options to purchase 40,000 shares of common stock were granted on both 
May 10, 1995 and September 15, 1995 to Eligible Directors of the Company.
Thereafter, through the date of the 1996 Annual Meeting of Stockholders, any new
director elected to the Board who is an Eligible Director shall automatically be
granted, on the effective date of such election, options to purchase an
aggregate of 40,000 shares of common stock at an option price equal to the fair
market value on the date of grant. Options granted under the 1992 Director Plan
shall become exercisable in four equal annual installments following the date of
grant if, and only if, the optionee is a director of the Company on such
anniversary date. The options expire ten years from the date of grant. The
number of stock options exercisable under this plan at September 30, 1995 was
40,000.

     On November 17, 1995, the Board of Directors approved, subject to
stockholder approval, the 1996 Director Stock Option Plan (the "1996 Director
Plan") for which 90,000 shares of common stock have been reserved. The 1996
Director Plan will replace the 1992 Director Plan. The terms of the 1996
Director Plan are essentially the same as the 1992 Director Plan, except that
each Eligible Director is automatically granted options to purchase 10,000
shares of common stock at the time of initial election to the Board of
Directors, and immediately following the meeting of stockholders every year,
each Eligible Director continuing in office after such meeting will
automatically be granted options to purchase 2,500 shares of common stock. No
additional options will be granted under the 1992 Director Plan, but the rights
and privileges of holders of outstanding options under the 1992 Director Plan
will not be adversely affected by the 1996 Director Plan.

     In conjunction with the Rasna merger, the Company assumed approximately
522,000 outstanding options on August 1, 1995. These assumed options were
granted at prices equal to the fair market value at the date of grant, become
exercisable in installments (generally ratably over four years) and expire ten
years from the date of grant. The Company does not intend to issue any
additional options under the Rasna stock option plan. The number of stock
options exercisable under this plan at September 30, 1995 was 191,000.

     The following table summarizes stock option transactions under all plans:

     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("FAS 123"). This statement establishes financial accounting and
reporting standards for stock-based employee compensation plans. While the
Company is reviewing the adoption and impact of FAS 123, it is expected that
this standard will have no impact on the Company's financial position or results
of operations. The Company will be required to adopt FAS 123 in fiscal 1997.

H. STOCK PURCHASE PLAN
 ................................................................................

The 1991 Employee Stock Purchase Plan (the "1991 Purchase Plan") enables
eligible employees to purchase the Company's common stock at 85% of the fair
market value of the stock on the date an offering commences or on the date an
offering terminates, whichever is lower. The 1991 Purchase Plan covers
substantially all employees, subject to certain limitations. Each employee may
elect to have up to 10% of his or her base pay

                                      32

<PAGE>
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       Parametric Technology Corporation

withheld and applied toward the purchase of shares in such offering (provided
that the aggregate amount of his or her base pay withheld may not exceed $10,000
in any fiscal year). The 1991 Purchase Plan covers an aggregate of up to 600,000
shares of common stock to be issued and sold to participating employees of the
Company through a series of eight, six-month offerings, beginning April 1, 1991.
In fiscal 1995, the stockholders approved amendments to the 1991 Purchase Plan
to add a series of nine additional six-month offerings, commencing six months
apart, beginning April 1, 1995, and to increase the number of shares authorized
for issuance under the 1991 Purchase Plan from 600,000 to 1,000,000.

     Purchases under the 1991 Purchase Plan for fiscal 1995, 1994 and 1993 were
77,361, 86,284 and 63,105 shares, generating proceeds to the Company of
$2,459,000, $2,031,000 and $1,425,000, respectively. At September 30, 1995,
approximately 640,000 shares of common stock were reserved for purchases under
the 1991 Purchase Plan.

I. EMPLOYEE BENEFIT PLAN
 ................................................................................

The Board of Directors in 1989 adopted the Parametric Technology Corporation
401(k) Savings Plan (the "Plan"), which is intended to qualify under Section
401(k) of the Internal Revenue Code of 1986, as amended. The Plan covers
substantially all employees. Each employee may elect to contribute to the Plan,
through payroll deductions, up to 15% of his or her salary, subject to certain
limitations. The Company makes matching contributions on behalf of each
participating employee in an amount equal to 50% of the amount contributed by
the employee up to a maximum 10% employee contribution. The employee's
entitlement to such Company contributions vests at a rate of 25% per year of
service.

     For the fiscal years ended September 30, 1995, 1994 and 1993, the Company
made matching contributions to the Plan which totaled $1,034,000, $738,000 and
$504,000, respectively.

     In conjunction with the Rasna merger, the Company will continue Rasna's
401(k) deferred tax savings plan for former Rasna employees who had contributed
funds to the plan, but no new contributions will be accepted. Under Rasna's
plan, participants were able to contribute up to 15% of their compensation,
subject to certain limitations, and Rasna was able to make discretionary
matching contributions. There have been no matching contributions made to the
Rasna plan.

J. SUPPLEMENTAL CASH FLOW INFORMATION
 ................................................................................

Cash paid for interest during the fiscal years ended September 30, 1995, 1994
and 1993 was $37,000, $125,000 and $97,000, respectively. Cash paid for income
taxes in fiscal 1995, 1994 and 1993 was $40,281,000, $22,279,000 and $9,268,000,
respectively. During fiscal 1995 and 1994, the Company acquired $108,000 and
$76,000 of fixed assets under capital leases, respectively.

K. BORROWING ARRANGEMENTS
 ................................................................................

The Company had a $5,000,000 unsecured demand line of credit with a bank, which
expired on January 31, 1995. There were no borrowings under this line during
fiscal 1995.

     Prior to the Rasna merger, Rasna had a $3,000,000 accounts receivable line
of credit available for its use. All amounts borrowed against this line were
paid in full prior to the merger date. Borrowings of $600,000 at September 30,
1994 under this line are included in accounts payable and accrued expenses.

L. COMMITMENTS
 ................................................................................

Leasing Arrangements

The Company leases its office facilities and certain equipment under operating
leases expiring at various dates through fiscal 2004. The Company also leases
computer equipment under capital leases which expire through fiscal 1998.

     At September 30, 1995, future minimum lease payments under capital and
operating leases with initial or remaining terms of one or more years are as
follows:

                      REPORT OF INDEPENDENT ACCOUNTANTS
                       Parametric Technology Corporation

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 sheet and the related consolidated statements
of income, of changes in 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, 1995 and 1994, and the results
of their operations and their cash flows for each of the three years in the
period ended September 30, 1995 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 Rasna Corporation, which statements reflect total assets of
$17,936,000 at December 31, 1994 and total revenue of $22,718,000 and
$16,223,000 for the years ended December 31, 1994 and 1993, respectively. 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 Rasna 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.

                         Independent Auditors' Report
                         ----------------------------


To the Board of Directors and Shareholders of Rasna Corporation:

We have audited the consolidated balance sheet of Rasna Corporation and its
subsidiaries as of December 31, 1994, and the related consolidated statements of
income, shareholders' equity and cash flows for the years ended December 31,
1994 and 1993 (not presented separately herein). 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 conducted our audits 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 audits provide a reasonable basis for our opinion.

In our opinion,
 such consolidated financial statements present fairly, in all
material respects, the financial position of Rasna Corporation and its
subsidiaries at December 31, 1994, and the results of their operations and their
cash flows for the years ended December 31, 1994 and 1993 in conformity with
generally accepted accounting principles.
