     Basic  earnings per share ("EPS") is computed by dividing net income by the
weighted average number of common shares outstanding during each period. Diluted
EPS is computed by dividing net income by the weighted  average number of common
shares and common  share  equivalents  outstanding  (if  dilutive)  during  each
period.  Common share  equivalents  include stock options.  The number of common
share  equivalents  outstanding  relating to stock options is computed using the
treasury stock method.

The  reconciliation  of the denominators used to calculate basic EPS and diluted
EPS for the  three-month  and  nine-month  periods ended  September 30, 2003 and
2002, respectively, are as follows (in thousands):

Stock options to acquire  1,386,000 and 3,071,000  shares for the quarters ended

for the nine months ended  September 30, 2003 and 2002,  respectively,  were not
included in the computations of diluted earnings per share because the effect of
including the stock options would have been anti-dilutive.

NOTE 4 - Comprehensive Income

Total comprehensive income for the quarters ended September 30, 2003 and 2002 is
$8.3 million and $6.5 million,  respectively,  and includes other  comprehensive
income of $361,000 and other comprehensive loss of $235,000,  respectively.  For
the first nine months of 2003 and 2002,  comprehensive  income is $23.2  million
and $18.8 million, respectively, and includes other comprehensive income of $1.1
million  and  other  comprehensive  loss  of  $2.7  million,  respectively.  The
Company's other  comprehensive  income is from foreign currency  translation and
unrealized  gains and losses on the Company's  forward and option  contracts and
securities available for sale.

NOTE 5 - Stock-Based Compensation Plans

The Company has two active stock-based compensation plans and one inactive plan.
The two  active  stock-based  compensation  plans are the 1994  Incentive  Stock
Option Plan and the  Employee  Stock  Purchase  Plan.  The  Company  follows the
disclosure-only   provisions  of  SFAS  No.  123,   Accounting  for  Stock-Based
Compensation,   as  amended  by  SFAS  No.  148,   Accounting  for   Stock-Based
Compensation  -  Transition  and  Disclosure.  As allowed by SFAS No.  123,  the
Company continues to apply the provisions of Accounting Principles Board Opinion
No. 25, Accounting for Stock issued to Employees, and related interpretations in
accounting for its plans.  Accordingly,  compensation  cost for stock options is
measured as the  excess,  if any, of the quoted  market  price of the  Company's
stock at the date of the grant over the amount an  employee  must pay to acquire
the stock. No compensation  cost has been recognized in the Company's  financial
statements   for  the  stock  option  plan  and  the  stock  purchase  plan.  If
compensation cost for the Company's two active  stock-based  compensation  plans
were determined based on the fair value at the grant date for awards under those
plans consistent with the method  established by SFAS No. 123, the Company's net
income and earnings per share would  approximate the pro-forma amounts below (in
thousands, except per share data):

NOTE 6 - Warranty Reserve

The Company offers a one-year limited  warranty on most hardware  products and a
90-day  warranty on software  products,  which is included in the sales price of
many of its products.  Provision is made for estimated  future warranty costs at
the time of sale.

NOTE 7 - Segment Information

While the Company sells its products to many different  markets,  its management
has chosen to organize  the  Company by  geographic  areas,  and as a result has
determined that it has one reportable segment. Substantially all of the interest
income,  interest  expense,  depreciation  and amortization is recorded in North
America. Net sales, operating income and identifiable assets,  classified by the
major  geographic  areas in which  the  Company  operates,  are as  follows  (in

NOTE 8 - Recently Issued Accounting Pronouncement

In May 2003, the Financial  Accounting Standards Board ("FASB") issued Statement
of  Financial  Accounting  Standards  ("SFAS") No. 150,  Accounting  for Certain
Financial  Instruments with Characteristics of Both Liabilities and Equity. This
Statement  establishes  standards  for how an  issuer  classifies  and  measures
certain  financial  instruments  with  characteristics  of both  liabilities and
equity.  It  requires  that an issuer  classify a financial  instrument  that is
within its scope as a liability (or an asset in some circumstances) because that
financial  instrument  embodies an obligation of the issuer.  This  Statement is
effective for financial instruments entered into or modified after May 31, 2003,
and  otherwise  is  effective  at the  beginning  of the  first  interim  period
beginning  after  June  15,  2003.  It is to be  implemented  by  reporting  the
cumulative  effect  of  a  change  in  an  accounting  principle  for  financial
instruments created before the issuance date of the Statement and still existing
at the beginning of the interim period of adoption. The adoption of SFAS No. 150
did not have a material effect on the Company's financial position or results of
operations as the Company has no debt.

NOTE 9 - Litigation

As reported in the two  previous  Form 10Q's of 2003,  the Company has filed two
complaints against The MathWorks, Inc. ("Defendant") for patent infringement. In
both complaints, the Company claimed the Defendant infringes certain of its U.S.
patents and the Defendant  challenged the validity and  enforceability  of those
patents and asserts that it does not infringe the claims of those patents.

The first  complaint was filed on January 25, 2001 in the U.S.  District  Court,
Eastern  District of Texas  (Marshall  Division).  On January 30, 2003, the jury
found infringement by the Defendant of three of the patents involved and awarded
the  Company  specified  damages.  On June 23,  2003,  the Court  entered  final
judgement in favor of the Company in an amount of  approximately  $4 million and
entered an  injunction  against  Defendant's  sale of its  Simulink  and related
products.  The  Court  stayed  the  injunction  pending  appeal  of the case and
required the Defendant to pay a specified  royalty on its U.S. sales of the same
products  during the pendency of appeal.  On July 22, 2003,  Defendant filed its
Notice of Appeal and the case is  currently  pending  on appeal  before the U.S.
Court of Appeals  for the  Federal  Circuit.  The final  judgement  has not been
recorded in the financial  statements of the Company  pending the disposition of
the appeal.

The second  complaint  was filed  October 21,  2002,  also in the U.S.  District
Court, Eastern District of Texas (Marshall Division) and on August 27, 2003, the
complaint was dismissed by agreement of the parties.

On January 15, 2003,  SoftWIRE  Technology,  LLC  ("SoftWIRE")  and  Measurement
Computing  Corporation ("MCC") filed a complaint against the Company in the U.S.
District  Court for the  District of  Massachusetts  asking the court to declare
that SoftWIRE does not infringe  certain of the Company's U.S.  patents and that
such patents are invalid and  unenforceable.  On February 21, 2003,  the Company
filed a complaint against SoftWIRE and MCC in the U.S.  District Court,  Eastern
District  of Texas  (Marshall  Division)  claiming  that both  SoftWIRE  and MCC
infringe the same and certain other of the Company's U.S. patents.  SoftWIRE and
MCC challenge the validity and  enforceability  of these patents and assert that
they do not infringe any of these patents.  In the Eastern District action,  the
Company seeks monetary damages and injunction of the sale of certain products of
SoftWIRE and MCC as well as  attorney's  fees and costs.  By order of the Court,
the Eastern  District action was transferred to the U.S.  District Court for the
District  of  Massachusetts  on May 9,  2003,  and the  parties  are  seeking to
consolidate this action with the  previously-filed  SoftWIRE action. On June 12,
2003,  SoftWIRE  moved for leave to amend its  complaint in order to allege that
the Company infringes two U.S. patents that SoftWIRE acquired by purchase on May
23, 2003. MCC joined  SoftWIRE's  motion to amend.  With respect to the two U.S.
patents that SoftWIRE  acquired,  SoftWIRE seeks monetary damages and injunction
of the sale of certain  products of the Company as well as  attorney's  fees and
costs.  The Company opposes  SoftWIRE's and MCC's motion for leave to amend. The
motion is currently pending before the Court.  Should the Court permit amendment
to allow assertion of SoftWIRE's patents,  the Company is prepared to vigorously
defend against SoftWIRE's claims and challenges the validity, enforceability and
alleged infringement of those patents.

NOTE 10 - Subsequent Event

The Company's Board of Directors  declared on October 23, 2003, a quarterly cash
dividend of $0.05 per common share,  payable  November 24, 2003, to shareholders
of record November 3, 2003.

     Net Sales.  Consolidated  net sales increased by $8.6 million or 9% for the
three months ended  September 30, 2003 to $104.6  million from $96.0 million for
the three months ended  September 30, 2002, and increased $19.7 million or 7% to
$304.0 million for the nine months ended  September 30, 2003 from $284.3 million
for the comparable period in the prior year. The increase in sales for the three
and nine months  ended  September  30, 2003 was  primarily  attributable  to the
introduction  of new and upgraded  products,  an early stage  recovery in global
manufacturing  and an increased market  acceptance of the Company's  products in
Asia.  Sales in the Americas in the third  quarter of 2003  increased by 1% from
the third  quarter of 2002 and sales in the  Americas  for the nine months ended
September 30, 2003 were flat with sales from the nine months ended September 30,
2002.



     Sales outside of North America,  as a percentage of consolidated  sales for
the quarter  ended  September  30, 2003  increased  to 51.4% from 47.5% over the
quarter ended  September 30, 2002 as a result of stronger  sales in Asia Pacific
and a stronger  Euro.  Sales  outside of North America for the nine months ended
September 30, 2003 increased to 51.6% from 48.1% in the  comparable  2002 period
as a result of stronger  sales in Asia  Pacific.  Compared to the  corresponding
periods in 2002, the Company's  European sales increased by 18% to $31.7 million
for the quarter  ended  September 30, 2003 and increased by 11% to $94.2 million
for the nine months ended September 30, 2003. Sales in Asia Pacific increased by
18% to $22.1  million for the quarter  ended  September 30, 2003 compared to the
same period in 2002 and increased 22% to $62.8 million for the nine months ended
September  30, 2003  compared to the same  period in 2002.  The Company  expects
sales outside of North America to continue to represent a significant portion of
its revenue.

     Sales made by the Company's direct sales offices in Europe and Asia Pacific
are denominated in local currencies, and accordingly, the U.S. dollar equivalent
of these sales is affected by changes in the foreign  currency  exchange  rates.
Between the third quarter of 2002 and the third quarter of 2003,  net of hedging
results,  the  change in the  exchange  rates had the effect of  increasing  the
Company's  consolidated  sales  by 2%;  increasing  European  sales  by 15%  and
decreasing  sales in Asia  Pacific by 15%.  The increase in sales as a result of
the  change in  exchange  rates was more than  offset by the  decrease  in local
currency product pricing in Europe. For 2003, year-to-date sales, net of hedging
results, the change in exchange rates had the effect of increasing the Company's
consolidated sales by 2%; increasing  European sales by 13% and decreasing sales
in Asia  Pacific by 15%.  Since most of the  Company's  international  operating
expenses are also incurred in local currencies, the change in exchange rates had
the effect of  increasing  operating  expenses  $5.2 million for the nine months
ended September 30, 2003 and by $1.5 million for the quarter ended September 30,
2003.

     Gross  Profit.  As a  percentage  of net sales,  gross profit for the third
quarter of 2003 remained constant at 73.8% compared to the third quarter of 2002
and  increased  to 73.5% for the first  nine  months of 2003 from  72.8% for the
comparable  period a year ago.  The gross  margin in the third  quarter  of 2003
remained constant compared to the comparable prior year period primarily because
favorable  foreign  exchange  rates and the impact of fixed charges  relative to
higher  sales  volume  totally  offset  the  unfavorable  effects  of  increased
amortization of capitalized software costs. The increase in the gross margin for
the first nine months of 2003  compared to the  comparable  prior year period is
primarily  attributable  to favorable  foreign  exchange rates and the favorable
impact  of fixed  charges  relative  to  higher  sales  volume.  There can be no
assurance  that the Company will maintain its  historical  margins.  The Company
believes its current manufacturing capacity is adequate to meet current needs.

     Sales and Marketing.  Sales and marketing expenses for the third quarter of
2003  increased  to $40.3  million,  a 9.8%  increase,  as compared to the third
quarter of 2002, and increased 10.7% to $117.0 million for the first nine months
of 2003 from the comparable 2002 period. As a percentage of net sales, sales and
marketing  expenses  were 38.5% and 38.2% for the quarters  ended  September 30,
2003 and 2002,  respectively,  and 38.5%  and  37.2% for the nine  months  ended
September  30, 2003 and 2002,  respectively.  Approximately  $1.6 million of the
increase in sales and  marketing  expenses for the quarter  ended  September 30,
2003,  is  attributable  to the increase in  international  sales and  marketing
personnel,  and  approximately  $1.4 million of the increase is  attributable to
increases  in  advertising  and  literature  costs and special  event  activity.
Approximately  8% of the total  increase in sales and marketing  expenses in the
third quarter of the current year was offset by a decrease in employoee benefits
expense  related to a reduction of the  estimated  health and medical  insurance
liability  resulting  from  the  Company's  additional  focus  on  these  costs.
Approximately  $6.5 million of the increase in sales and marketing  expenses for
the nine months  ended  September  30, 2003 is  attributable  to the increase in
international sales and marketing  personnel,  and approximately $3.7 million of
the increase is attributable  to increases in advertising  and literature  costs
and special event activity.  The Company expects sales and marketing expenses in
future periods to increase in absolute dollars, and to fluctuate as a percentage
of sales based on recruiting,  initial marketing and advertising  campaign costs
associated  with major new  product  releases  and entry into new market  areas,
investment in web sales and marketing efforts,  increasing product demonstration
costs and the timing of domestic and international conferences and trade shows.




     Research and Development.  Research and development  expenses  increased to
$18.4 million for the quarter ended  September  30, 2003, a 14.1%  increase,  as
compared to $16.1  million for the three months ended  September  30, 2002,  and
increased  5.7% to $50.5  million for the nine months ended  September  30, 2003
from $47.8 million in the comparable 2002 period.  As a percentage of net sales,
research  and  development  expenses  represented  17.6% and 16.8% for the third
quarters ended  September 30, 2003 and 2002,  respectively,  and 16.6% and 16.8%
for the nine  months  ended  September  30,  2003 and  2002,  respectively.  The
increase in research and  development  costs in absolute  amounts in each period
and as a percentage of sales for the quarter ended  September 30, 2003 is due to
increases  in  personnel  costs from hiring of  additional  product  development
engineers  and from the  decrease in  capitalized  software  development  costs.
Research and development  personnel  increased from 802 at September 30, 2002 to
869 at September 30, 2003.  Approximately  14% of the total increase in resrarch
and development  expenses in the third quarter of the current year was offset by
a decrease in employee  benefits expense related to a reduction of the estimated
health and medical insurance liability  resulting from the Company's  additional
focus  on these  costs.  The  Company  plans to  continue  making a  significant
investment  in  research  and  development  in order to remain  competitive  and
support revenue growth.

     The Company capitalizes  software development costs in accordance with SFAS
No. 86,  Accounting for the Costs of Computer  Software to be Sold,  Leased,  or
Otherwise Marketed.  The Company amortizes such costs over the related product's
estimated economic useful life, generally three years,  beginning when a product
becomes  available for general release.  Software  amortization  expense totaled
$1.8 million and $953,000 for the quarters  ended  September  30, 2003 and 2002,
respectively,  and $4.0  million and $3.0  million  during the nine months ended
September  30,  2003  and  2002,   respectively.   Software   development  costs
capitalized  were $1.0 million and $1.5 million for the quarters ended September
30, 2003 and 2002, respectively, and $9.4 million and $3.0 million for the first
nine months of 2003 and 2002, respectively.

     General and  Administrative.  General and  administrative  expenses for the
quarter ended  September 30, 2003 decreased 7% to $8.8 million from $9.4 million
for the comparable prior year period. For the first nine months of 2003, general
and administrative  expenses increased 11.4% to $29.0 million from $26.1 million
for the first nine months of 2002.  As a  percentage  of net sales,  general and
administrative  expenses  decreased to 8.4% for the quarter ended  September 30,
2003 from 9.8% for the third  quarter of 2002.  During the first nine  months of
2003, general and administrative  expenses as a percentage of sales increased to
9.6% from 9.1% in the comparable prior year period.  The decrease in general and
administrative expenses in absolute amounts and as a percentage of sales for the
quarter  ended  September  30, 2003,  from the  comparable  prior year period is
attributable to decreased litigation costs of $860,000,  associated with a legal
action by the Company brought against The MathWorks, Inc. in 2001 to enforce the
Company's  intellectual  property  (See Note 9 -  Litigation).  The  increase in
general and  administrative  expenses for the nine month period ended  September
30, 2003 from the  comparable  prior year period is  primarily  attributable  to
unfavorable  foreign  exchange rates,  increased  litigation costs and increased
international   personnel   costs.   The  Company   expects   that  general  and
administrative  expenses in future periods will increase in absolute amounts and
will fluctuate as a percentage of revenue.

     Interest  Income,  Net.  Net interest  income in the third  quarter of 2003
decreased to $570,000  from  $785,000 in the third quarter of 2002 and decreased
to $1.9  million  for the first nine  months of 2003 from $2.4  million  for the
comparable 2002 period. The decrease in interest income for the quarter and nine
months  ended  September  30,  2003 were due to lower  yields  on the  Company's
investments. The primary source of interest income is from the investment of the
Company's cash.

     Net Foreign  Exchange  Gain  (Loss).  The Company  experienced  net foreign
exchange  losses of $209,000 in the third  quarter of 2003 compared to losses of
$612,000 in the third quarter of 2002.  Net foreign  exchange  gains of $116,000
were  recognized  for the first nine  months of 2003  compared to losses of $1.3
million for the first nine months of 2002.  These  results are  attributable  to
movements between the U.S. dollar and the local currencies in countries in which
the Company's sales  subsidiaries are located.  The Company recognizes the local
currency as the functional currency of its international subsidiaries.

     The Company utilizes foreign currency forward contracts to hedge a majority
of its foreign currency-denominated  receivables in order to reduce its exposure
to significant foreign currency  fluctuations.  The Company typically limits the
duration of its "receivables" foreign currency forward contracts to 90 days.



     The Company also utilizes foreign  currency  forward  contracts and foreign
currency  purchased  option  contracts  in  order  to  reduce  its  exposure  to
fluctuations in future foreign currency cash flows. The Company  purchases these
contracts  for up to 100% of its  forecasted  cash flows in selected  currencies
(primarily  the euro,  yen and pound  sterling) and limits the duration of these
contracts to 40 months.  The foreign  currency  purchased  option  contracts are
purchased  "at-the-money"  or  "out-of-the-money."  As a result,  the  Company's
hedging  activities  only  partially  address  its  risks  in  foreign  currency
transactions,  and  there  can  be no  assurance  that  this  strategy  will  be
successful.  The Company does not invest in contracts for speculative  purposes.
The  Company's  hedging  strategy  reduced  the foreign  exchange  gains by $1.9
million  during the quarter ended  September  30, 2003,  and reduced the foreign
exchange gains by $7.1 million for the nine months ended September 30, 2003.

     Provision  for Income Taxes.  The  provision  for income taxes  reflects an
effective tax rate of 25% for the three and nine months ended September 30, 2003
and 28% for the three and nine months ended  September 30, 2002. The decrease in
the  effective  rate  resulted  from  income tax  benefits  attributable  to the
extraterritorial  income  exclusion and a change in the  distribution  of income
among  taxing   jurisdictions,   particularly   the  impact  of  the   Company's
manufacturing  facility in Hungary.  The  Company's  effective tax rate is lower
than  the U.S.  federal  statutory  rate of 35%  primarily  as a  result  of the
extraterritorial income exclusion,  tax-exempt interest and reduced tax rates in
certain foreign jurisdictions.

Liquidity and Capital Resources

     The Company is currently financing its operations and capital  expenditures
through  cash flow from  operations.  At  September  30,  2003,  the Company had
working capital of  approximately  $235.1 million  compared to $211.5 million at
December 31, 2002. Net cash provided by operating activities for the nine months
ended September 30, 2003 totaled $35.5 million.

     Accounts  receivable  increased to $68.3 million at September 30, 2003 from
$63.0 million at December 31, 2002.  Days sales  outstanding  increased to 60 at
September 30, 2003 compared to 53 at September 30, 2002.  Consolidated inventory
balances  decreased to $38.4 million at September 30, 2003 from $39.2 million at
December 31, 2002.  Inventory  turns of 2.8  represent an increase from turns of
2.6 at September  30,  2002.  Cash used in the first nine months of 2003 for the
purchase of property and equipment totaled $12.9 million, for the capitalization
of  internally  developed  software  costs  totaled $9.4  million,  acquisitions
totaled $5.3 million and additions to other intangibles totaled $1.0 million.

     For the nine months ended September 30, 2003, cash provided by the issuance
of common stock  totaled $11.5  million,  and cash used for payment of dividends
totaled $2.6  million.  The issuance of common stock was to employees  under the
Employee Stock Purchase and Stock Option Plans.

     The Company currently expects to fund expenditures for capital requirements
as well as  liquidity  needs  created  by  changes  in  working  capital  from a
combination of available cash and short-term  investment balances and internally
generated funds. As of September 30, 2003, the Company had no debt  outstanding.
The Company  believes  that cash flow from  operations,  if any,  existing  cash
balances  and  short-term  investments  will  be  sufficient  to meet  its  cash
requirements for at least the next twelve months.  Cash requirements for periods
beyond the next twelve  months will depend on the Company's  profitability,  its
ability to manage working capital requirements and its rate of growth.

Financial Risk Management

     The Company's  international sales are subject to inherent risks, including
fluctuations in local  economies;  difficulties in staffing and managing foreign
operations;  greater  difficulty in accounts  receivable  collection;  costs and
risks of  localizing  products  for  foreign  countries;  unexpected  changes in
regulatory requirements,  tariffs and other trade barriers;  difficulties in the
repatriation of earnings and burdens of complying with a wide variety of foreign
laws.  The Company's  sales outside of North  America are  denominated  in local
currencies, and accordingly, the Company is subject to the risks associated with
fluctuations  in currency  rates.  In particular,  increases in the value of the
dollar  against  foreign  currencies  decrease the U.S.  dollar value of foreign
sales  requiring the Company either to increase its price in the local currency,
which could render the Company's  product  prices  noncompetitive,  or to suffer
reduced revenues and gross margins as measured in U.S.  dollars.  These dynamics
have  adversely  affected  revenue growth in  international  markets in previous
years.  The Company's  foreign  currency  hedging program  includes both foreign
currency forward and purchased option contracts to reduce the effect of exchange
rate  fluctuations.  However,  the hedging program will not eliminate all of the
Company's foreign exchange risks. (See "Net Foreign Exchange Gain (Loss)").



     The  marketplace  for the  Company's  products  dictates  that  many of the
Company's  products be shipped  very quickly  after an order is  received.  As a
result, the Company is required to maintain significant inventories.  Therefore,
inventory  obsolescence  is a risk for the Company  due to frequent  engineering
changes,  shifting customer demand,  the emergence of new industry standards and
rapid  technological  advances  including the introduction by the Company or its
competitors of products  embodying new technology.  While the Company  maintains
valuation   allowances  for  excess  and  obsolete  inventories  and  management
continues to monitor the adequacy of such valuation allowances,  there can be no
assurance that such valuation allowances will be sufficient.

     The Company has no debt or  off-balance  sheet debt.  As of  September  30,
2003,  the  Company  did not have  any  relationships  with  any  unconsolidated
entities  or  financial  partnerships,  such as  entities  often  referred to as
structured  finance entities,  which would have been established for the purpose
of  facilitating  off-balance  sheet  arrangements.  As such, the Company is not
exposed to any financing,  liquidity,  market or credit risk that could arise if
the Company were engaged in such relationships.

Market Risk

     The Company is exposed to a variety of risks,  including  foreign  currency
fluctuations and changes in the market value of its  investments.  In the normal
course of business,  the Company employs established  policies and procedures to
manage its exposure to  fluctuations  in foreign  currency values and changes in
the market value of its investments.

     Foreign Currency Hedging  Activities.  The Company's  objective in managing
its exposure to foreign  currency  exchange rate  fluctuations  is to reduce the
impact of adverse  fluctuations in such exchange rates on the Company's earnings
and cash flow.  Accordingly,  the Company  utilizes  purchased  foreign currency
option  contracts  and forward  contracts to hedge its  exposure on  anticipated
transactions and firm commitments. The principal currencies hedged are the euro,
British  pound and  Japanese  yen.  The Company  monitors  its foreign  exchange
exposures regularly to ensure the overall  effectiveness of its foreign currency
hedge  positions.  However,  there can be no  assurance  the  Company's  foreign
currency hedging activities will substantially offset the impact of fluctuations
in currency exchange rates on its results of operations and financial  position.
Based on the foreign exchange instruments  outstanding at September 30, 2003, an
adverse  change  (defined  as 20% in the Asian  currencies  and 10% in all other
currencies)  in exchange  rates would result in a decline in the aggregate  fair
market value of all  instruments  outstanding  of  approximately  $13.0 million.
However,  as the  Company  utilizes  foreign  currency  instruments  for hedging
anticipated and firmly committed  transactions,  management believes that a loss
in fair value for those instruments will be substantially offset by increases in
the value of the underlying exposure.

     Short-term  Investments.  The fair value of the  Company's  investments  in
marketable securities at September 30, 2003 was $138.2 million. Investments with
maturities  beyond one year are  classified as short-term  based on their highly
liquid nature and because such marketable securities represent the investment of
cash that is available for current operations.  The Company's  investment policy
is to manage its investment  portfolio to preserve principal and liquidity while
maximizing the return on the investment portfolio through the full investment of
available funds. The Company diversifies the marketable  securities portfolio by
investing  in  multiple  types of  investment-grade  securities.  The  Company's
investment  portfolio is primarily  invested in  short-term  securities  with at
least an  investment  grade rating to minimize  interest rate and credit risk as
well as to provide  for an  immediate  source of funds.  Based on the  Company's
investment portfolio and interest rates at September 30, 2003, a 100 basis point
increase or decrease in interest rates would result in a decrease or increase of
approximately  $700,000,  respectively,  in the  fair  value  of the  investment
portfolio.  Although  changes in interest rates may affect the fair value of the
investment  portfolio and cause unrealized gains or losses, such gains or losses
would not be realized unless the investments are sold.



Recently Issued Accounting Pronouncement

     In May 2003,  the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial  Accounting  Standards  ("SFAS") No. 150,  Accounting for
Certain  Financial  Instruments  with  Characteristics  of Both  Liabilities and
Equity.  This Statement  establishes  standards for how an issuer classifies and
measures certain financial  instruments with characteristics of both liabilities
and equity.  It requires that an issuer classify a financial  instrument that is
within its scope as a liability (or an asset in some circumstances) because that
financial  instrument  embodies an obligation of the issuer.  This  Statement is
effective for financial instruments entered into or modified after May 31, 2003,
and  otherwise  is  effective  at the  beginning  of the  first  interim  period
beginning  after  June  15,  2003.  It is to be  implemented  by  reporting  the
cumulative  effect  of  a  change  in  an  accounting  principle  for  financial
instruments created before the issuance date of the Statement and still existing
at the beginning of the interim period of adoption. The adoption of SFAS No. 150
did not have a material effect on the Company's financial position or results of
operations as the Company has no debt.

Factors Affecting the Company's Business and Prospects

     U.S./Global Economic Slowdown. As occurred in 2001 and 2002, the markets in
which the Company does business could again experience the negative effects of a
slowdown in the U.S., and/or Global economies.  Additionally,  the Company could
be impacted by the effects of any  recurrence of the SARS virus,  either through
increased  difficulty or costs of the export of products into affected  regions,
the import of components used in our products from affected regions,  and/or the
effects  the virus or costs to contain  the virus have on the economy in regions
in which  the  Company  does  business,  particularly  Asia,  which has been the
highest  growth region of the Company over the past two years.  The worsening of
the U.S. or Global  economies  could  result in reduced  purchasing  and capital
spending in any of the markets served by the Company which could have a material
adverse effect on the Company's operating results.

     Budgets.  The Company has  established  an operating  budget for 2003.  The
Company's spending for the remainder of the year could exceed this budget due to
a number of factors;  including:  additional marketing costs for conferences and
tradeshows;   increased  costs  from  the  over-hiring  of  product  development
engineers or other  personnel;  increased  manufacturing  costs  resulting  from
component supply shortages and/or component price fluctuations and/or additional
expenses  related to  intellectual  property  litigation.  Any future  decreased
demand for our products could result in decreased  revenue and could require the
Company to revise its budget and reduce expenditures.  Exceeding the established
operating  budget or failing to reduce  expenditures in response to any decrease
in revenue  could  have a material  adverse  effect on the  Company's  operating
results.

     Risk of  Component  Shortages.  As has  occurred  in the past and as may be
expected to occur in the future,  supply  shortages  of  components  used in our
products, including sole source components, can result in significant additional
costs and  inefficiencies  in  manufacturing.  If the Company is unsuccessful in
resolving any such component shortages,  it will experience a significant impact
on the timing of revenue and/or an increase in  manufacturing  costs,  either of
which would have a material adverse impact on the Company's operating results.

     Fluctuations  in  Quarterly  Results.  The  Company's  quarterly  operating
results  have  fluctuated  in the past and may  fluctuate  significantly  in the
future due to a number of  factors,  including:  changes in the mix of  products
sold; the availability and pricing of components from third parties  (especially
sole sources);  the timing of orders;  level of pricing of international  sales;
fluctuations in foreign  currency  exchange rates; the difficulty in maintaining
margins,  including the higher margins  traditionally  achieved in international
sales;  and  changes in pricing  policies by the  Company,  its  competitors  or
suppliers.  Specifically,  if the local  currencies  in which the Company  sells
weaken against the U.S. dollar,  and if the local sales prices cannot be raised,
the Company will experience a deterioration of its gross and net profit margins.
If the U.S. dollar  strengthens in the future,  it could have a material adverse
effect on gross and net profit margins.



     As has  occurred in the past and as may be expected to occur in the future,
new software  products of the Company or new operating  systems of third parties
on which the Company's products are based, often contain bugs or errors that can
result in reduced  sales and/or cause the  Company's  support costs to increase,
either of which could have a material adverse impact on the Company's  operating
results.  Furthermore,  the Company has  significant  revenues from customers in
industries such as semiconductors, automated test equipment, telecommunications,
aerospace,  defense and  automotive  which are cyclical in nature.  Downturns in
these industries could have a material adverse effect on the Company's operating
results.

     In recent years,  with the exception of 2001,  the Company's  revenues have
been  characterized  by seasonality,  with revenues  typically being  relatively
constant in the first, second and third quarters,  growing in the fourth quarter
and being  relatively  flat or declining  from the fourth quarter of the year to
the first quarter of the following year. The Company believes the seasonality of
its  revenue  results  from  the  international  mix  of  its  revenue  and  the
variability of the budgeting and purchasing  cycles of its customers  throughout
each  international  region. In addition,  total operating  expenses have in the
past tended to be higher in the second and third  quarters of each year,  due to
recruiting and increased intern personnel expenses.

     New  Product  Introductions  and  Market  Acceptance.  The  market  for the
Company's  products is characterized  by rapid  technological  change,  evolving
industry  standards,   changes  in  customer  needs  and  frequent  new  product
introductions, and is therefore highly dependent upon timely product innovation.
The Company's  success is dependent on its ability to  successfully  develop and
introduce  new and  enhanced  products  on a timely  basis to replace  declining
revenues  from older  products,  and on increasing  penetration  in domestic and
international  markets.  In the past,  the Company has  experienced  significant
delays between the announcement and the commercial availability of new products.
Any  significant  delay in releasing new products could have a material  adverse
effect on the ultimate success of a product and other related products and could
impede  continued  sales of  predecessor  products,  any of which  could  have a
material  adverse  effect on the Company's  operating  results.  There can be no
assurance  that the Company will be able to introduce new products in accordance
with announced  release dates,  that new products will achieve market acceptance
or that  any such  acceptance  will be  sustained  for any  significant  period.
Failure of new  products to achieve or sustain  market  acceptance  could have a
material adverse effect on the Company's operating results.  Moreover, there can
be no assurance that the Company's international sales will continue at existing
levels or grow in  accordance  with the  Company's  efforts to increase  foreign
market penetration.

     Risks  Associated  with Increased  Development of Web Site. The Company has
devoted significant  resources in developing its Web site as a key marketing and
sales  tool and  expects to  continue  to do so in the  future.  There can be no
assurance that the Company will be successful in its attempt to leverage the Web
to  increase  sales.  The  Company  hosts its Web site  internally.  Failure  to
successfully  maintain the Web site and to protect it from hackers  could have a
significant adverse impact on the Company's operating results.

     Operation  in  Intensely  Competitive  Markets.  The  markets  in which the
Company  operates  are  characterized  by  intense   competition  from  numerous
competitors,  some of which  are  divisions  of large  corporations  having  far
greater  resources  than the  Company,  and the Company  expects to face further
competition  from new market entrants in the future. A key competitor is Agilent
Technologies  Inc.  ("Agilent").  Agilent  offers  its own  line  of  instrument
controllers   and  also  offers   hardware  and  software  add-on  products  for
third-party  desktop  computers and  workstations  that provide  solutions  that
directly compete with the Company's virtual instrumentation products. Agilent is
aggressively  advertising and marketing  products that are competitive  with the
Company's products.  Because of Agilent's strong position in the instrumentation
business,  changes in its marketing  strategy or product  offerings could have a
material adverse effect on the Company's operating results.

     The  Company  believes  its  ability to compete  successfully  depends on a
number of factors  both within and outside its control,  including:  new product
introductions by competitors;  product pricing; quality and performance; success
in  developing  new  products;  adequate  manufacturing  capacity  and supply of
components and materials; efficiency of manufacturing operations;  effectiveness
of sales and marketing  resources and strategies;  strategic  relationships with
other suppliers;  timing of new product introductions by the Company; protection
of the  Company's  products by  effective  use of  intellectual  property  laws;
general market and economic  conditions;  and government  actions throughout the
world.  There  can be no  assurance  that the  Company  will be able to  compete
successfully in the future.



     Management  Information  Systems.  The  Company  relies  on  three  primary
regional centers for its management information systems. As with any information
system,  unforeseen issues may arise that could affect  management's  ability to
receive adequate,  accurate and timely financial information which in turn could
inhibit effective and timely decisions.  Furthermore, it is possible that one or
more of the Company's  three  regional  information  systems could  experience a
complete  or partial  shutdown.  If such a shutdown  occurred  near the end of a
quarter it could impact the Company's product shipments and revenues, as product
distribution  is heavily  dependent  on the  integrated  management  information
systems in each region. Accordingly,  operating results in that quarter would be
adversely  impacted.  The  Company  is  working  to  achieve  reliable  regional
management  information  systems to control  costs and  improve  the  ability to
deliver its products in substantially  all of its direct markets  worldwide.  No
assurances  can be given that the  Company's  efforts  will be  successful.  The
failure to receive  adequate,  accurate and timely financial  information  could
inhibit management's ability to make effective and timely decisions.

     During the quarter  ended  September  30,  2003,  the Company  successfully
upgraded its Americas business  applications  suite to Oracle's latest web-based
release,  11i.  However,  there can be no  assurance  that the Company  will not
experience  difficulties  with the new system.  Difficulties with the system may
interrupt normal Company  operations,  including the ability to: provide quotes,
process orders,  ship products,  provide  services and support to our customers,
bill and track our customers,  fulfill contractual obligations and otherwise run
our business.  Any disruptions of the system may have a material  adverse effect
on the Company's operating results.

     Risks  Associated  with  International  Operations  and Foreign  Economies.
International  sales are subject to inherent  risks,  including  fluctuations in
local  economies,  difficulties  in staffing  and managing  foreign  operations,
greater  difficulty  in  accounts  receivable  collection,  costs  and  risks of
localizing  products for foreign  countries,  unexpected  changes in  regulatory
requirements, tariffs and other trade barriers, difficulties in the repatriation
of earnings  and the burdens of complying  with a wide variety of foreign  laws.
The Company must also comply with various import and export regulations. Failure
to comply with these  regulations  could result in fines and/or  termination  of
import and export privileges,  which could have a material adverse effect on the
Company's operating results.  Additionally,  the regulatory  environment in some
countries is very  restrictive as their  governments  try to protect their local
economy and value of their local currency against the U.S. dollar. Sales made by
the  Company's  international  direct  sales  offices are  denominated  in local
currencies,  and  accordingly,  the U.S.  dollar  equivalent  of these  sales is
affected by changes in the foreign  currency  exchange rates.  Between the third
quarter of 2002 and the third  quarter  of 2003,  net of  hedging  results,  the
change in exchange rates had the effect of increasing the Company's consolidated
sales  by 2% as  compared  to the  third  quarter  of  2002.  Since  most of the
Company's   international   operating   expenses  are  also  incurred  in  local
currencies,  the change in exchange rates had the effect of increasing operating
expenses by $1.5 million for the quarter  ended  September 30, 2003, as compared
to the comparable  prior year period.  If the U.S. dollar weakens in the future,
it could result in the Company  having to reduce prices locally in order for its
products to remain  competitive  in the local  marketplace.  If the U.S.  dollar
strengthens  in the future,  it could have a  materially  adverse  effect on the
Company's operating results.

     Expansion of  Manufacturing  Capacity.  During 2001, the Company  completed
construction  of a second  manufacturing  facility.  This facility is located in
Hungary and became  operational  in the fourth  quarter of 2001.  This  facility
sources a significant  portion of the Company's sales.  Currently the Company is
continuing  to  develop  and  implement   information  systems  to  support  its
operation.  This facility and its operation are also subject to risks associated
with a new  manufacturing  facility  and with  doing  business  internationally,
including difficulty in managing manufacturing  operations in a foreign country,
difficulty  in  achieving  or  maintaining  product  quality,   interruption  to
transportation  flows for delivery of components to us and finished goods to our
customers,  and changes in the country's  political or economic  conditions.  No
assurance  can  be  given  that  the  Company's   efforts  will  be  successful.
Accordingly,  failure to deal with these factors could result in interruption in
the  facility's  operation or delays in expanding its capacity,  either of which
could have a material adverse effect on the Company's operating results.



     Income Tax Rate.  The  Company  established  a  manufacturing  facility  in
Hungary in 2001. As a result of certain foreign investment  incentives available
under  Hungarian  law,  the profit from the  Company's  Hungarian  operation  is
currently  exempt from income tax.  These  benefits  may not be available in the
future due to changes in  Hungary's  political  condition  and/or tax laws.  The
reduction or elimination of these foreign investment  incentives would result in
the reduction or  elimination  of certain tax benefits  thereby  increasing  the
Company's  future effective income tax rate, which could have a material adverse
effect on the Company's operating results.

     The  Company   receives  a   substantial   income  tax  benefit   from  the
extraterritorial  income exemption ("ETI") under U.S. law. The ETI rules provide
that a percentage of the profits from products and intangibles exported from the
U.S. are exempt from U.S.  tax.  This benefit may not be available in the future
as the ETI  has  been  ruled  an  illegal  export  subsidy  by the  World  Trade
Organization.  The repeal of the ETI would result in the elimination of this tax
benefit thereby increasing the Company's future effective income tax rate, which
could have a material adverse effect on the Company's operating results.

     Products Dependent on Certain  Industries.  Sales of the Company's products
are   dependent   on   customers  in  certain   industries,   particularly   the
telecommunications, semiconductor, automotive, automated test equipment, defense
and aerospace industries.  As experienced in the past, and as may be expected to
occur in the future, downturns characterized by diminished product demand in any
one or more of these  industries  could result in decreased  sales,  which could
have a material adverse effect on the Company's operating results.

     Dependence  on Key  Suppliers.  The Company's  manufacturing  processes use
large volumes of high-quality  components and subassemblies  supplied by outside
sources.  Several of these  components  are  available  through  sole or limited
sources.   Sole-source  components  purchased  by  the  Company  include  custom
application-specific  integrated  circuits  ("ASICs") and other components.  The
Company has in the past  experienced  delays and quality  problems in connection
with sole-source  components,  and there can be no assurance that these problems
will not recur in the future.  Accordingly,  the failure to receive  sole-source
components  from  suppliers  could  result in a material  adverse  effect on the
Company's revenues and operating results.

     Stock-based  Compensation  Plans.  The Company  has two active  stock-based
compensation   plans  and  one  inactive  plan.   The  two  active   stock-based
compensation  plans are the 1994  Incentive  Stock  Option Plan and the Employee
Stock  Purchase  Plan.  The Company  currently  adheres to the  disclosure  only
provisions  of SFAS  No.  123,  as  amended  by SFAS  No.  148,  Accounting  for
Stock-Based   Compensation  -  Transition  and  Disclosure,   and  as  such,  no
compensation cost has been recognized in the Company's financial  statements for
the stock  option plan and the stock  purchase  plan.  The Company is  currently
monitoring the recent discussions related to possible new regulations  regarding
the  accounting  treatment for stock  options.  The Company will comply with any
changes in the  accounting  of stock  options  required by the FASB. If the fair
value based method of accounting  for stock options  established  under SFAS No.
123 were adopted  effective  January 1, 2003 under the prospective  method,  the
Company estimates it would have recognized stock option expense of approximately
$261,000 and $462,000 for the quarter and nine month periods ended September 30,
2003, respectively. The impact of the adoption of the fair value based method of
accounting for stock options established under SFAS No. 123 effective January 1,
2003 under the  retroactive  restatement  method is  reflected in Note 5 - Stock
Based Compensation Plans.

     Proprietary  Rights and  Intellectual  Property  Litigation.  The Company's
success depends in part on its ability to obtain and maintain  patents and other
proprietary rights relative to the technologies used in its principal  products.
Despite the Company's  efforts to protect its proprietary  rights,  unauthorized
parties  may have in the past  infringed  or violated  certain of the  Company's
intellectual  property  rights.  The  Company  may from  time to time  engage in
litigation  to protect its  intellectual  property  rights.  In  monitoring  and
policing its intellectual  property rights, the Company may be required to spend
significant resources.  Additionally, as is typical in the industry, the Company
from  time to time may be  notified  that it is  infringing  certain  patent  or
intellectual  property  rights  of  others.  There  can  be  no  assurance  that
intellectual  property  litigation  initiated  in  the  future  will  not  cause
significant  litigation  expense,  liability  and a  diversion  of  management's
attention  which may have a material  adverse effect on the Company's  operating
results.



     Dependence on Key Management and Technical Personnel. The Company's success
depends to a  significant  degree upon the  continued  contributions  of its key
management,   sales,   marketing,   research  and  development  and  operational
personnel,  including Dr. Truchard,  the Company's  Chairman and Chief Executive
Officer, and other members of senior management and key technical personnel. The
Company  has no  agreements  providing  for  the  employment  of any of its  key
employees for any fixed term and the  Company's  key  employees may  voluntarily
terminate  their  employment  with  the  Company  at any  time.  The loss of the
services of one or more of the  Company's key employees in the future could have
a material  adverse affect on operating  results.  The Company also believes its
future  success  will depend  upon its ability to attract and retain  additional
highly skilled management,  technical,  marketing, research and development, and
operational  personnel with  experience in managing  large and rapidly  changing
companies,  as  well as  training,  motivating  and  supervising  employees.  In
addition, the recruiting  environment for software engineering,  sales and other
technical professionals is very competitive.  Competition for qualified software
engineers is particularly intense and is likely to result in increased personnel
costs.  Failure to attract or retain qualified  software engineers could have an
adverse effect on the Company's operating results. The Company also recruits and
employs foreign  nationals to achieve its hiring goals primarily for engineering
and software positions. There can be no guarantee that the Company will continue
to be able to recruit  foreign  nationals  at the current  rate.  These  factors
further intensify  competition for key personnel,  and there can be no assurance
that the Company will be  successful  in retaining its existing key personnel or
attracting and retaining additional key personnel. Failure to attract and retain
a sufficient number of technical  personnel could have a material adverse effect
on the Company's operating results.

     Risk of Product  Liability Claims.  The Company's  products are designed to
provide  information  upon which the users may rely.  The  Company  attempts  to
assure the quality and accuracy of the processes contained in its products,  and
to limit its product  liability  exposure  through  contractual  limitations  on
liability,  including  disclaimers in its "shrink wrap" license  agreements with
end-users.  If future products contain errors that produce  incorrect results on
which  users  rely,  customer  acceptance  of the  Company's  products  could be
adversely  affected.  Further,  the Company could be subject to liability claims
that could have a material adverse effect on the Company's  operating results or
financial position.  Although the Company maintains liability  insurance,  there
can be no assurance that such insurance or the  contractual  provisions  used by
the Company to limit its liability will be sufficient.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

     Response to this item is included in "Item 2 - Management's  Discussion and
Analysis of Financial Conditions and Results of Operations - Market Risk" above.

Item 4.  Controls and Procedures

     The Company's Chief Executive Officer and Chief Financial Officer, based on
the evaluation of the Company's  disclosure  controls and procedures (as defined
in Rules  13a-15(e)  and  15d-15(e) of the  Securities  Exchange Act of 1934, as
amended)  required  by  paragraph  (b) of  Rule  13a-15  or Rule  15d-15,  as of
September 30, 2003,  have concluded that the Company's  disclosure  controls and
procedures  were  effective  to ensure the  timely  collection,  evaluation  and
disclosure  of  information  relating to the Company that would  potentially  be
subject to disclosure under the Securities Exchange Act of 1934, as amended, and
the rules and regulations promulgated thereunder.  During the three months ended
September  30, 2003,  there were no changes in the Company's  internal  controls
over financial  reporting  identified in connection with the evaluation required
by paragraph (d) of the Rule 13a-15 or Rule 15d-15 that has materially affected,
or is  reasonably  likely to  materially  affect,  the  internal  controls  over
financial reporting.



                          PART II - OTHER INFORMATION


ITEM 1.  LEGAL PROCEEDINGS

As reported in the two  previous  Form 10Q's of 2003,  the Company has filed two
complaints against The MathWorks, Inc. ("Defendant") for patent infringement. In
both complaints, the Company claimed the Defendant infringes certain of its U.S.
patents and the Defendant  challenged the validity and  enforceability  of those
patents and asserts that it does not infringe the claims of those patents.

The first  complaint was filed on January 25, 2001 in the U.S.  District  Court,
Eastern  District of Texas  (Marshall  Division).  On January 30, 2003, the jury
found infringement by the Defendant of three of the patents involved and awarded
the  Company  specified  damages.  On June 23,  2003,  the Court  entered  final
judgement  in favor of the  Company  in an amount of  approximately  $4  million
dollars and entered an injunction  against  Defendant's sale of its Simulink and
related products. The Court stayed the injunction pending appeal of the case and
required the Defendant to pay a specified  royalty on its U.S. sales of the same
products  during the pendency of appeal.  On July 22, 2003,  Defendant filed its
Notice of Appeal and the case is  currently  pending  on appeal  before the U.S.
Court of Appeals  for the  Federal  Circuit.  The final  judgement  has not been
recorded in the financial  statements of the Company  pending the disposition of
the appeal.

The second  complaint  was filed  October 21,  2002,  also in the U.S.  District
Court, Eastern District of Texas (Marshall Division) and on August 27, 2003, the
complaint was dismissed by agreement of the parties.

On January 15, 2003,  SoftWIRE  Technology,  LLC  ("SoftWIRE")  and  Measurement
Computing  Corporation ("MCC") filed a complaint against the Company in the U.S.
District  Court for the  District of  Massachusetts  asking the court to declare
that SoftWIRE does not infringe  certain of the Company's U.S.  patents and that
such patents are invalid and  unenforceable.  On February 21, 2003,  the Company
filed a complaint against SoftWIRE and MCC in the U.S.  District Court,  Eastern
District  of Texas  (Marshall  Division)  claiming  that both  SoftWIRE  and MCC
infringe the same and certain other of the Company's U.S. patents.  SoftWIRE and
MCC challenge the validity and  enforceability  of these patents and assert that
they do not infringe any of these patents.  In the Eastern District action,  the
Company seeks monetary damages and injunction of the sale of certain products of
SoftWIRE and MCC as well as  attorney's  fees and costs.  By order of the Court,
the Eastern  District action was transferred to the U.S.  District Court for the
District  of  Massachusetts  on May 9,  2003,  and the  parties  are  seeking to
consolidate this action with the  previously-filed  SoftWIRE action. On June 12,
2003,  SoftWIRE  moved for leave to amend its  complaint in order to allege that
the Company infringes two U.S. patents that SoftWIRE acquired by purchase on May
23, 2003. MCC joined  SoftWIRE's  motion to amend.  With respect to the two U.S.
patents that SoftWIRE  acquired,  SoftWIRE seeks monetary damages and injunction
of the sale of certain  products of the Company as well as  attorney's  fees and
costs.  The Company opposes  SoftWIRE's and MCC's motion for leave to amend. The
motion is currently pending before the Court.  Should the Court permit amendment
to allow assertion of SoftWIRE's patents,  the Company is prepared to vigorously
defend against SoftWIRE's claims and challenges the validity, enforceability and
alleged infringement of those patents.
