           PROXY STATEMENT FOR THE PARAMETRIC TECHNOLOGY CORPORATION
                      2002 ANNUAL MEETING OF STOCKHOLDERS

                INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why Did You Send Me This Proxy Statement?

As a stockholder, you have the right to attend and vote at the Parametric
Technology Corporation (PTC) 2002 Annual Meeting of Stockholders. If you attend
the Annual Meeting, you may vote your shares directly. Whether or not you
attend, you may vote by proxy, which allows you to direct another person to
vote your shares at the meeting on your behalf. The PTC Board of Directors is
soliciting your proxy to encourage your participation in voting at the meeting
and to obtain your support on the proposal presented.

There are two parts to our proxy solicitation: this proxy statement and the
enclosed voting instruction form (which may also be called a "proxy card"). The
proxy statement explains the matter to be voted on at the Annual Meeting. You
use the voting instruction form to authorize your shares to be voted as you
wish.

We will begin mailing this proxy statement on January 7, 2002 to all
stockholders entitled to vote. If you owned our common stock at the close of
business on December 20, 2001, you are entitled to vote. On that date, there
were 260,585,349 shares of common stock outstanding. Common stock is our only
class of voting stock.

How Many Votes Do I Have?

You have one vote for each share of common stock that you owned at the close of
business on December 20, 2001. Your proxy card or other voting instruction form
indicates the number.

How Do I Vote by Proxy?

To vote, simply complete, sign and return the form before the meeting, and your
shares will be voted as you direct. If you wish, in most cases you may vote by
telephone or the Internet instead.

When you vote, you are giving your "proxy" to the individuals we have
designated to vote your shares as you direct at the meeting. If you sign the
form but do not make specific choices, they will vote your shares to elect the
two current directors nominated by the Board. If any matter not listed in the
Notice of Meeting is presented at the Annual Meeting, they will vote your
shares in accordance with their best judgment. At the time we began printing
this Proxy Statement, we knew of no matters that needed to be acted on at the
meeting other than as discussed in this Proxy Statement.

Whether you plan to attend the Annual Meeting or not, we urge you to complete,
sign and date the enclosed voting instruction form and to return it promptly in
the envelope provided. Returning the form will not affect your right to attend
the Annual Meeting and vote.

How Do I Vote by Telephone or the Internet?

Instead of submitting your vote by mail on the enclosed voting instruction
form, you may vote by telephone or the Internet. Please note that there may be
separate telephone and Internet arrangements depending on whether you are a
registered stockholder (that is, if you hold your stock in your own name) or
you hold your shares in "street name" (that is, in the name of a brokerage firm
or bank that holds your securities account). In either case, you must follow
the procedures described on your voting instruction form.

                                      1



The telephone and Internet voting procedures are designed to authenticate
stockholders' identities, to allow stockholders to give their voting
instructions and to confirm that stockholders' instructions have been recorded
properly.

We encourage you to vote by the Internet. If you do so, please authorize us to
deliver future annual reports and proxy statements to you by e-mail. This
lowers costs and speeds delivery.

May I Revoke My Proxy?

Yes. You may change your vote after you send in your voting instructions by
following any of these procedures. For a registered stockholder to revoke a
proxy:

    .  Send in another signed voting instruction form with a later date; or

    .  Send a letter revoking your proxy to PTC's Clerk at the address
       indicated on page 16 under "Information About Stockholder Proposals"; or

    .  Attend the Annual Meeting, notify us in writing that you are revoking
       your proxy and vote in person.

A holder of stock in street name must follow the procedures required by the
brokerage firm or bank to revoke a proxy. You should contact that firm directly
for more information on these procedures.

How Do I Vote in Person?

If you plan to attend the Annual Meeting and wish to vote in person, we will
give you a ballot when you arrive. If your shares are held in street name, you
must bring an account statement or letter from the brokerage firm or bank
showing that you were the beneficial owner of the shares on December 20, 2001
in order to be admitted to the meeting. To be able to vote, you will need to
obtain a "legal proxy" from the holder of record.

What Is the Vote Required? How Is It Affected by Broker Non-Votes and
Abstentions?

If your shares are held in street name, the broker or bank may vote your shares
on the proposal if it does not receive instructions from you. Because the
directors elected at the meeting will be those receiving the highest number of
votes, if you abstain from voting or if your broker or bank does not vote on
the proposal, it will not count as a vote against the proposal.

Is Voting Confidential?

Our policy is to keep all the proxies, ballots and voting tabulations
confidential. The Inspectors of Election will forward to management any written
comments that you make on the proxy card without providing your name.

What Are the Costs of Soliciting These Proxies?

PTC will pay all the costs of soliciting these proxies. In addition to mailing
these proxy materials, our directors and employees may solicit proxies by
telephone, fax or other electronic means of communication, or in person. We
will reimburse banks, brokers, nominees and other fiduciaries for the expenses
they incur in forwarding the proxy materials to you.

                                      2



How Do I Obtain an Annual Report on Form 10-K?

A copy of our Annual Report on Form 10-K for the year ended September 30, 2001,
was included with this Proxy Statement and is available on our Web site at
www.ptc.com. If you would like another copy, we will send you one without
charge. Please write to:

   Investor Relations
   Parametric Technology Corporation
   140 Kendrick Street
   Needham, MA 02494

or by telephone at (781) 370-5000 or e-mail at IR@ptc.com.

Where Can I Find the Voting Results?

We will publish the voting results on PTC's Website at www.ptc.com following
the Annual Meeting and in our Form 10-Q for the second quarter of 2002, which
we will file with the Securities and Exchange Commission ("SEC") in May 2002.

Whom Should I Call if I Have any Questions?

If you have any questions about the Annual Meeting or your ownership of PTC
common stock, please contact PTC Investor Relations by telephone at (781)
370-5000 or e-mail at IR@ptc.com.

Other Matters

While the Notice of Meeting calls for transaction of any other business that
may further or relate to the matters described in the Notice, the Board of
Directors does not know of any other matters that may come before the meeting.

otherwise act, in accordance with their judgment on such matters.

                        INFORMATION ABOUT THE DIRECTORS

   business law and mergers and acquisitions.


Family Relationships

Mr. Harrison, a Class III director, and Paul J. Cunningham, PTC's Executive
Vice President, Americas Sales, are first cousins.

Board Meetings

PTC's Board usually meets four times per year in regularly scheduled meetings
but will meet more often if necessary. The Board met five times during fiscal
2001.

                                      4



The Committees of the Board

The Board has three standing committees: the Audit, Compensation and Officers'
Stock Option Committees.

The Audit Committee

The Audit Committee examines accounting processes, reviews our financial
disclosures and meets privately, outside the presence of PTC management, with
the independent auditors to discuss our internal accounting control policies
and procedures. The Committee reports on such matters to our Board of
Directors. The Committee also considers and recommends the selection of our
independent auditors, reviews the performance of the independent auditors in
the annual audit and in assignments unrelated to the audit and reviews the fees
of the independent auditors. The Audit Committee operates under a written
charter adopted by the Board of Directors.

Messrs. Marx, Porter (Chairman) and Posternak currently serve as members of the
Audit Committee. Mr. Marx and Mr. Posternak are "independent directors" under
the rules of the Nasdaq Stock Market governing the qualifications of members of
the Audit Committee. Neither has ever been an employee of PTC or any
subsidiary. Although Professor Porter has never been an employee of PTC or any
subsidiary, we have hired him from time to time as a speaker and organizer of
executive management seminars on PTC's behalf. The terms of that arrangement
for fiscal 2001 are described in "Information About Certain Insider
Relationships" on page 7. As a result, Professor Porter would not be considered
"independent" under the Nasdaq rules. However, the Board has determined that
these activities do not interfere with his ability to exercise independent
judgment in carrying out his responsibilities and that, in light of Professor
Porter's unique knowledge, background and financial acumen, his continued
membership on the Audit Committee serves the best interests of PTC and its
stockholders. The Audit Committee met six times during fiscal 2001. The
Committee's report for 2001 appears on page 14.

The Compensation and Stock Option Committees

The Compensation Committee makes recommendations to the Board of Directors
regarding executive and employee compensation and administers PTC's bonus
programs, stock option plans and employee stock purchase plans. Each year, the
Committee reports to you on executive compensation. The Committee's report for
fiscal 2001 appears on pages 11 to 12.

Messrs. Goldman (Chairman) and Grierson currently serve as members of the
Compensation Committee. Both Messrs. Goldman and Grierson qualify as
"independent directors" under the Nasdaq Stock Market rules discussed above
under "The Audit Committee." This committee met twice during fiscal 2001.

During fiscal 2001, Messrs. Goldman (Chairman) and Grierson also constituted
the Officers' Stock Option Committee, which grants stock options to executive
officers of the company. The Officers' Stock Option Committee met once during
fiscal 2001.

How We Compensate Our Directors


                                 
Annual Cash Fee                               Each director of PTC who is not an employee of PTC or our
                                              subsidiaries, other than the Chairman of the Board, receives an
                                              annual cash fee of $10,000 per year. Mr. Posternak, a non-
                                              employee and Chairman of the Board, was paid an annual cash
                                              fee of $75,000 for his service in the capacity of Chairman in
                                              fiscal 2001.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires that our
insiders--our directors, executive officers and 10%-or-greater
stockholders--file reports with the SEC on their initial beneficial ownership
of PTC common stock and any subsequent changes. They must also provide us with
copies of the reports.

Based on our review of all reports furnished to us, we believe that all of our

(1) The exercise price of each option is 100% of the fair market value of our
    common stock on the date the option was granted. The exercise price may be
    paid in cash or, subject to certain limitations for shares previously
    acquired upon exercise of options, in shares of common stock, or in a
    combination of cash and shares. All options granted are exercisable in four
    equal annual installments, commencing one year after the date of grant.
    These options may become exercisable sooner as described in "Employment
    Agreements With Executive Officers" on page 14.
(2) The dollar amounts under these columns are the result of calculations at
    the 5% and 10% appreciation rates set by the SEC and, therefore, are not
    intended to forecast possible future appreciation, if any, in the price of
    our common stock. No gain to the optionees is possible without an increase
    in the price of our common stock, which will benefit all stockholders
    proportionately.
(3) In order to realize the potential values over the ten-year option term set
    forth in the 5% and 10% columns of this table, the per share price of the
    common stock at the end of the option term would be as follows:

Report of the Compensation Committee

Executive Compensation Programs

Our executive compensation programs, which contain no special perquisites,
consist of three principal elements: base salary, cash bonus and stock options.
Our objective is to emphasize incentive compensation in the form of bonuses and
stock option grants, rather than base salary. Our Board of Directors sets the
annual base salary for executives after consideration of the recommendations of
the Compensation Committee. Prior to making its recommendations, the
Compensation Committee reviews historical compensation levels of the
executives, evaluates past performance and assesses expected future
contributions of the executives. In making the recommendations regarding base
salaries, the Committee considers generally available information regarding
salaries prevailing in the industry but does not tie salaries to any particular
indices.

We maintain incentive plans under which executive officers (including the Chief
Executive Officer) are paid cash bonuses after the end of each fiscal year. The
bonuses under the incentive plans are based in part on our achievement of
certain financial targets established by our Board of Directors before the
start of each fiscal year. The incentive plans for fiscal 2001 set forth
several performance targets including, for each participating officer, earnings
per share and revenue targets. Because earnings and revenue targets for the
fiscal year were not met, Messrs. Harrison, Gillis and Cohen were not eligible
to receive a cash bonus under our incentive plans in fiscal 2001. However, in
order to acknowledge and reward Messrs. Gillis and Cohen for their significant
contributions to PTC in 2001, the Board of Directors awarded them non-incentive
plan bonuses for fiscal 2001. Messrs. Brown and Cunningham, who receive sales
commissions based on revenue, are not eligible for incentive bonuses.

Total compensation for executive officers also includes long-term incentives
offered by stock options. Stock options are instrumental in promoting the
alignment of long-term interests between our executive officers and
stockholders due to the fact that executives realize gains only if the stock
price increases over the fair market value at the date of grant and the
executives exercise their options. In recommending the amount of such grants,
the Officers' Stock Option Committee considered the contributions of each
executive to our overall success in fiscal 2001, the responsibilities to be
assumed in the upcoming fiscal year, the appropriate incentives for the
promotion of our long-term growth and grants to other executives in the
industry holding comparable positions, as well as the executive's position
within our company. It has been our practice to fix the exercise price of

                                      11



options, which generally become exercisable in equal annual installments over a
period of four years commencing one year after the date of grant, at 100% of
the fair market value on the date of grant. Therefore, the long-term value
realized by executives through option exercises can be directly linked to the
enhancement of stockholder value.

Compensation Deductibility

Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"),
imposes a limit on tax deductions for annual compensation in excess of one
million dollars paid by a corporation to its chief executive officer and the
other four most highly compensated executive officers of the corporation. This
provision excludes certain forms of "performance based compensation," including
stock options, from the compensation taken into account for the purposes of
that limit. The Committee believes that, although it is desirable for executive
compensation to be tax deductible whenever in the Committee's judgment that
would be consistent with the objectives pursuant to which the particular
compensation is paid, we should compensate our executive officers fairly in
accordance with the guidelines discussed in this report and not be unduly
limited by the anticipated tax treatment. Accordingly, the total compensation
paid to an executive officer in any year may exceed the amount that is
deductible. The Compensation Committee will continue to assess the impact of
Section 162(m) of the Code on its compensation practices and determine what
further action, if any, is appropriate.

Chief Executive Officer Compensation

Mr. Harrison's performance was evaluated, and his compensation determined at
the beginning of fiscal 2001 in accordance with the factors described above
applicable to executive officers generally, and his base salary was not
increased for fiscal 2001. For fiscal 2002, Mr. Harrison's salary also remains
unchanged. Because earnings and revenue targets for the fiscal year were not
met, Mr. Harrison was not eligible to receive a cash bonus under our incentive
plans in fiscal 2001. The Board of Director's granted Mr. Harrison options to
purchase 800,000 shares of PTC's common stock. The amount of this option grant
reflects Mr. Harrison's overall contribution to PTC during fiscal 2001,
including his efforts in positioning PTC for future growth and his anticipated
future contributions, as well as the factors applicable to executive officers
generally described above.

Stock Performance Graph

The following Stock Performance Graph compares the cumulative stockholder
return on our common stock from September 30, 1996 to September 28, 2001 with
the cumulative total return of the Nasdaq (U.S. Companies) Index and the Nasdaq
Computer & Data Processing Index (approximately 777 companies) over the same
period. The Stock Performance Graph assumes that the value of the investment in
PTC common stock and each of the comparison groups was $100 on September 30,
1996 and assumes the reinvestment of dividends. We have never declared a
dividend on our common stock. The stock price performance depicted in the graph
below is not necessarily indicative of future price performance.

Employment Agreements with Executive Officers

Agreement with Mr. Harrison

Mr. Harrison has an agreement that provides him with certain benefits in the
event of a termination of his employment under certain circumstances and upon
the occurrence of certain events. If we elect to terminate his employment
(other than for "cause," as defined in the agreement) or effect a "change in
status" (which, as defined in the agreement, includes a diminution in title,
responsibilities or compensation), he is entitled to receive during the
six-month period following such an event (or until such earlier date as he
commences employment with another company), a salary at a rate equal to two
times the highest annual salary (excluding bonuses) received by him in the
prior six months. The agreement also provides that the outstanding options he
holds under our option plans become exercisable (i) in full upon a "change in
control" (which in general includes (a) any person or entity becoming the
beneficial owner of 50% or more of the voting power of PTC, (b) a change in a
majority of our directors or (c) the approval by the stockholders of a merger
or consolidation in which our stockholders do not have majority voting power of
the surviving entity, or (d) our liquidation or a sale or disposition of all or
substantially all of our assets) or upon the death or disability of Mr.
Harrison and (ii) for the number of shares of Common Stock for which they would
have otherwise become exercisable had his employment continued for one year
following a termination of his employment without "cause" or a "change in
status."

Agreements with Messrs. Cohen, Cunningham, Gillis and Brown

PTC has entered into similar agreements with Messrs. Cohen, Cunningham, Gillis
and Brown which provide that (i) in the event we terminate their employment
without "cause," they are entitled to receive, during the six-month period
following notice of termination (or until such earlier date as they commence
employment with another company), a salary at a rate equal to the highest
annual salary (excluding bonuses) received in the prior six months and (ii) in
the event of a change in control of PTC, their outstanding options under PTC's
option plans become exercisable in full.

                        INFORMATION ABOUT OUR AUDITORS

PricewaterhouseCoopers LLP served as PTC's independent auditors for fiscal 2001
and has reported on our 2001 consolidated financial statements. The Board of
Directors has re-appointed PricewaterhouseCoopers LLP for fiscal year 2002.
Representatives of PricewaterhouseCoopers LLP are expected to be present at our
Annual Meeting. They will have the opportunity to make a statement if they so
desire and will also be available to respond to appropriate questions from
stockholders.

Report of the Audit Committee

The Audit Committee reviews PTC's financial reporting process on behalf of the
Board of Directors. In fulfilling its responsibilities, the Committee has
reviewed and discussed the audited financial statements for fiscal 2001 with
management and the independent auditors. In this process, the Committee met
with the independent auditors, with and without management present, to discuss
the results of the auditors' examinations and the overall quality of PTC's
financial reporting.

The Committee has discussed with the independent auditors the matters required
to be discussed by Statement on Auditing Standards No. 61, Communication with
Audit Committees. In addition, the Committee has discussed with the independent
auditors the auditors' independence from PTC and its management, including the
matters in the written disclosures received from the auditors as required by
Independence Standards Board Standard No. 1, Independence Discussions with
Audit Committees. The Audit Committee also considered whether the independent
auditor's provision of the other, non-audit related services to the Company,
which are referred to in "Independent Auditor's Fees" below, is compatible with
maintaining such auditor's independence.

                                      14



Based on the Committee's discussions with management, the representations of
the independent auditors and the Committee's review of the report of the
independent auditors to the Committee, the Committee recommended that the Board
of Directors include the audited financial statements in PTC's Annual Report on
Form 10-K for fiscal 2001 for filing with the Securities and Exchange
Commission.
