                       PARAMETRIC TECHNOLOGY CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. BASIS OF PRESENTATION:

   The accompanying unaudited consolidated financial statements include the
accounts of the Company and its wholly owned subsidiaries, and have been
prepared by the Company in accordance with generally accepted accounting
principles.  In the opinion of management, the accompanying unaudited
consolidated financial statements contain all adjustments, consisting only of
those of a normal recurring nature, necessary for a fair presentation of the
Company's financial position, results of operations and cash flows at the dates
and for the periods indicated.  While the Company believes that the disclosures
presented are adequate to make the information not misleading, these financial
statements should be read in conjunction with the consolidated financial
statements and related notes included in the Company's Annual Report on Form 10-
K for the fiscal year ended September 30, 1996.

   The results of operations for the three-month and six-month periods ended
March 29, 1997 are not necessarily indicative of the results expected for the
full fiscal year.


2. NEW ACCOUNTING PRONOUNCEMENTS

   In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share." SFAS
No. 128 establishes a different method of computing net income per share than is
currently required under the provisions of Accounting Principles Board Opinion
No. 15. Under SFAS No. 128, the Company will be required to present both basic
net income per share and diluted net income per share. Basic net income per
share for the three-month and six-month periods ended March 29, 1997 would have
been $.42 and $.80 per share, respectively as compared with $.29 and $.55 per
share for the corresponding periods in fiscal 1996. The impact of SFAS No. 128
on the calculation of diluted net income per share for these quarters is not
expected to be materially different from primary earnings per share. The Company
plans to adopt SFAS No. 128 in its first quarter for fiscal 1998 and at that
time all historical net income per share data presented will be restated to
conform to the provisions of SFAS No. 128.

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


   Parametric Technology Corporation is the CAD/CAM/CAE (computer-aided design,
manufacturing and engineering) industry's leading supplier of software tools
used to automate the mechanical development of a product from its conceptual
design through its release into manufacturing.

   Information provided by the Company, including information contained in this
Quarterly Report on Form 10-Q, or by its spokespersons from time to time may
contain forward-looking statements concerning projected financial performance,
industry segment growth, product development and commercialization or other
aspects of future operations. In particular, the statements in this Report
concerning anticipated revenue, geographical growth rates and projected expenses
made pursuant to the safe harbor established by recent securities legislation
are based on the assumptions and expectations of the Company's management at the
time such statements are made. The Company cautions investors that its
performance (and, therefore, any forward-looking statement) is subject to risks
and uncertainties. Important information about the basis for those assumptions
including factors that may cause actual results to vary from those forecast are
discussed below and are also contained in "Important Factors Regarding Future
Results" included in the "Management's Discussion and Analysis of Financial
Condition and Results of Operations" section in the 1996 Annual Report to
Stockholders, incorporated herein by reference.

RESULTS OF OPERATIONS

   Revenue, including license and service revenues, for the three-month and six-
month periods ended March 29, 1997 was $198,012,000 and $381,513,000,
respectively, compared with $140,493,000 and $265,890,000 for the three-month
and six-month periods ended March 30, 1996.  These totals represent increases of
41% for the three-month period and 43% for the six-month period over the
corresponding periods in fiscal 1996.  Net income, as a percentage of revenue,
was 27%  for the three-month and six-month periods ended March 29, 1997 compared
to 26% in the corresponding periods in fiscal 1996.  This represents an increase
in net income of  44% and 47%  from the three-month and six-month periods ended
March 30, 1996.
 
   The Company derives its revenue from the sale and support of software used in
the mechanical segment of the CAD/CAM/CAE industry. Revenue growth in the three-
month and six-month periods ended March 29, 1997 reflects the continued
worldwide acceptance of the Company's products and services and the Company's
ongoing investment in expanding its worldwide direct sales force. License
revenue was $147,054,000 and $285,496,000 for the three-month and six-month
periods ended March 29, 1997, a 42% and 47% increase from $103,420,000 and
$194,850,000 for the corresponding periods in fiscal 1996. This growth results
from an increase in the number of seats of software licensed and from a higher
price realized per seat. A seat of software generally consists of various
software products configured to serve the needs of a single end user. The
Company licensed 7,475 and 14,459 seats of software respectively in the three-
month and six-month periods ended March 29, 1997, an increase of 37% and 38%
from 5,446 and 10,454 seats of software in the comparable periods in fiscal
1996. 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 the three months and six months ended March 29, 1997 was $19,700,
compared with an average price of $19,000 and $18,600 for the same periods in
fiscal 1996. The average price per seat has increased as a result of customers
purchasing configurations of seats containing more modules and an increase in
the percentage of the Company's revenue derived from international markets,
where the prices have typically been higher than in North America.

   Service revenue is derived from the sale of software maintenance contracts
and the performance of training and consulting services.  Service revenue was
$50,958,000 and $96,017,000 for the three-month and six-month periods ended
March 29, 1997, an increase of 37% and 35% from $37,073,000 and $71,040,000 for
the comparable periods in fiscal 1996.  The increase in service revenue is a
result of the growth in the Company's installed customer base and, to a lesser
extent, increased training and consulting services performed for these
customers.

   The Company derived 56% and 57% of revenue from sales to international
customers in the three-month and six-month periods ended March 29, 1997,
compared with 55% and 54% for the same periods in fiscal 1996.  The increase in
international revenue is primarily attributable to continued international
acceptance of the Company's products and services and the growth

                                       7

 
in the sales force in Europe and Asia/Pacific, although revenue derived from
Japan was weaker than anticipated due in part to the strengthening of the dollar
in relationship to the yen. The Company has taken measures to strengthen results
in the Asia/Pacific region and anticipates that total revenue will increase
throughout fiscal 1997 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; however, growth in international
revenue will continue to be affected by foreign exchange rates and the stronger
dollar's impact on the Company's ability to forecast quarter to quarter results.
Although the Company expects revenues to grow throughout fiscal 1997, there can
be no assurance that quarterly revenue growth rates and/or geographical growth
rates will be comparable with those achieved in the three-month and six-month
periods ended March 29, 1997. The rate of continued revenue growth throughout
the remainder of fiscal 1997 depends upon the strength of the U.S. dollar as
well as the Company's ability to implement recent measures taken to strengthen
results in the Asia/Pacific region, to adequately manage the Company's exposure
to foreign currency fluctuations, to continue to penetrate the mechanical
segment of the CAD/CAM/CAE industry, to attract and retain skilled personnel,
and to deliver timely product enhancements.

   Cost of license revenue consists of the amortization of capitalized computer
software costs and costs associated with reproducing software, printing user
manuals, royalties, packaging and shipping.  The increase in cost of license
revenue is a result of the increase in the number of seats licensed and the
royalty costs associated with those licenses during the three-month and six-
month periods ended March 29, 1997 as compared to the corresponding periods in
fiscal 1996.  Cost of service revenue includes the costs associated with
training and consulting personnel, such as salaries and related costs and
travel, and costs related to software maintenance, including costs incurred for
customer support personnel and the release of maintenance updates.  The increase
in cost of service revenue resulted primarily from growth in the staffing
necessary to generate and support increased worldwide service revenue and
provide ongoing quality customer support to the Company's increasing installed
base.  Combined, these expenses increased to $18,561,000 and $36,109,000 for the
three-month and six-month periods ended March 29, 1997 from $13,389,000 and
$25,843,000 for the corresponding periods in fiscal 1996.  Total cost of revenue
as a percentage of revenue remained stable between 9% and 10% for both the
three-month and six-month periods ended March 29, 1997 and the corresponding
periods in fiscal 1996.

   Sales and marketing expenses primarily include salaries, sales commissions,
travel and facility costs.  Sales and marketing expenses increased to
$77,263,000 and $148,924,000 for the three-month and six-month periods ended
March 29, 1997 from $56,303,000 and $106,754,000 for the corresponding period in
fiscal 1996.  These costs decreased as a percentage of revenue to 39% for  both
the three-month and six-month periods ended March 29, 1997, compared with 40%
for the comparable periods in fiscal 1996.  The absolute increase in these
expenses was due primarily to worldwide expansion of the sales force and sales
commissions associated with higher revenue.  Total sales and marketing headcount
increased to 1,877 at March 29, 1997, an increase of 36% from 1,379 at March 30,
1996.  The Company expects to continue the growth of its worldwide sales and
marketing organization during fiscal 1997, reflecting the Company's commitment
to focus its resources on increasing its installed base and to continue to
expand its global market penetration.  The Company's ability to meet this
expectation depends upon its ability to attract and retain highly skilled
technical, managerial and sales personnel.

   The Company continued to make significant investments in research and
development, consisting principally of salaries and benefits, expenses
associated with product translations, costs of computer equipment used in
software development, and facility expenses.  Research and development expenses
increased to $13,292,000 and $25,426,000 for the three-month and six-month
periods ended March 29, 1997 from $8,901,000 and $16,726,000 for the
corresponding periods in fiscal 1996.  Total research and development expenses
increased to 7% of revenue for the three-month and six-month periods ended March
29, 1997, compared with 6% for the same periods in fiscal 1996.  The Company
believes that research and development expenditures are essential to maintaining
its competitive position in the mechanical CAD/CAM/CAE industry and expects the
expenditure levels to increase in absolute dollars throughout fiscal 1997.

   General and administrative expenses include the costs of corporate, finance,
information technology, human resources and administrative functions of the
Company.  These expenses increased to $9,719,000 and $18,424,000 for the three-
month and six-month periods ended March 29, 1997 from $6,814,000 and $12,748,000
for the corresponding periods in fiscal 1996.  General and administrative
expenses as a percentage of revenue remained constant at 5% for the three-month
and six-month periods ended March 29, 1997 and March 30, 1996. The absolute
increase in these expenses was primarily due to the hiring of additional
employees necessary to support the Company's worldwide growth.

                                       8

 
   Other income, net, primarily includes interest income and expense and foreign
currency gains and losses.  Other income decreased to $2,450,000 and $5,075,000
for the three-month and six-month periods ended March 29, 1997 compared with
$2,651,000 and $5,674,000 for the corresponding periods in fiscal 1996.  As the
international portion of the Company's business continues to increase, a growing
percentage of the Company's revenue and expenses is transacted in foreign
currencies.  In order to reduce its exposure to fluctuations in foreign exchange
rates, the Company engages in hedging transactions involving the use of forward
foreign exchange contracts in the primary European and Asian currencies.

   The Company's effective tax rate for the three-month and six-month periods
ended March 29, 1997 was 35%, compared with 36.2% for the same periods in fiscal
1996.  The difference between the effective and statutory federal tax rate was
due primarily to the benefits of tax-exempt interest income and the tax benefits
from the use of the foreign sales corporation, offset by the impact of state
income taxes.

   The number of worldwide employees increased 32% to 3,133 at March 29, 1997
compared with 2,365 at March 30, 1996. Employment increased significantly to
support higher revenues and international expansion, with the largest portion of
this growth occurring in the sales department.

LIQUIDITY AND CAPITAL RESOURCES

   As of March 29, 1997, the Company had $212,088,000 of cash and cash
equivalents and $289,528,000 of investments.  Net cash generated by operating
activities and proceeds from issuance of the Company's stock under stock plans
provided sufficient resources to fund the Company's headcount growth, capital
asset needs and stock repurchases for the six months ended March 29, 1997.  Net
cash provided by operating activities, consisting primarily of net income from
operations before depreciation and amortization and increases in working
capital, was $139,202,000 for the six-month period ended March 29, 1997 compared
with $89,911,000 for the corresponding period in fiscal 1996.  Net cash used by
investing activities totaled $57,350,000 for the six-month period ended March
29, 1997, compared with $94,254,000 for the corresponding period in fiscal 1996.
The decrease is principally due to the proceeds from the sale of investments and
the timing associated with those investments.  Investment activities consisted
primarily of purchases and sales of investments, and additions to property and
equipment.  The Company acquired $13,427,000 of capital equipment consisting
primarily of computer equipment, software, and office equipment to meet the
needs resulting from the growth in employee headcount, continued expansion of
its worldwide sales and support operations and increased investment in
information technologies and in computer workstations to keep field and
development employees current with changes in the hardware and software
marketplace. For the remainder of fiscal 1997, the Company plans to continue
spending at current levels; however, the level of spending will be dependent on
various factors, including the growth of the business and general economic
conditions. Financing activities, consisting primarily of proceeds from issuance
of common stock offset by the purchases of treasury stock, used $66,926,000 for
the six months ended March 29, 1997 and $6,290,000 for the six months ended
March 30, 1996. The 1997 increase was due principally to higher stock
repurchases under the Company's stock repurchase program.

   On May 12, 1994, the Company announced that its Board of Directors had
authorized a plan that allows the Company to repurchase up to 6,000,000 shares
of its common stock.  The Company intends to repurchase these 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.  During the three-month and six-month periods ended March 29,
1997, the Company repurchased 977,000 and 1,757,000 shares at a cost of
$54,898,500 and $95,020,000, respectively, of which 585,000 remained in treasury
on March 29, 1997.  Since the inception of the plan, the Company has repurchased
3,850,000 shares.  Ongoing repurchases will be funded through the use of
available cash, cash generated from operations and cash received from stock
option exercises and employee stock purchase plan purchases.

   The Company believes that existing cash and short-term investment balances,
together with cash generated from operations and issuance of the Company's
common stock under stock plans, will be sufficient to meet the Company's
currently projected working capital, financing and capital expenditure
requirements through at least fiscal 1997, subject to the risks and
uncertainties referred to herein.
