                        NATIONAL INSTRUMENTS CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - Basis of Presentation

The accompanying  unaudited  consolidated financial statements should be read in
conjunction with the consolidated financial statements and notes thereto for the
year ended  December 31, 2001,  included in the Company's  annual report on Form
10-K,  filed with the  Securities  and  Exchange  Commission.  In the opinion of
management,  the  accompanying  consolidated  financial  statements  reflect all
adjustments  (consisting only of normal recurring items) considered necessary to
present fairly the financial  position of National  Instruments  Corporation and
its  consolidated  subsidiaries  at June 30, 2002 and December 31, 2001, and the
results of operations for the three-month  and six-month  periods ended June 30,
2002 and 2001, and the cash flows for the six-month  periods ended June 30, 2002
and 2001. Operating results for the three-month and six-month periods ended June
30, 2002 are not necessarily  indicative of the results that may be expected for
the year ending December 31, 2002.

NOTE 2 - Earnings Per Share

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  six-month  periods  ended June 30, 2002 and 2001,
respectively, are as follows (in thousands):

NOTE 5 - 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

NOTE 6 - Recently Issued Accounting Pronouncements

In May 2002, the Financial  Accounting Standards Board ("FASB") issued Statement
of  Financial   Accounting  Standards  ("SFAS")  No.  145,  Rescission  of  FASB
Statements No. 4, 44, and 64,  Amendment of FASB Statement No. 13, and Technical
Corrections  as of April 2002.  The  Statement  rescinds SFAS No. 4 and requires
that only unusual or  infrequent  gains and losses from  extinguishment  of debt
should be classified as  extraordinary  items,  consistent  with APB Opinion 30.
This  Statement  amends SFAS No. 13 to  eliminate an  inconsistency  between the
required accounting for sale-leaseback  transactions and the required accounting
for certain lease  modifications  that have economic effects that are similar to
sale-leaseback  transactions.   This  Statement  also  amends  certain  existing
authoritative  pronouncements  to make various  technical  corrections,  clarify
meanings, or describe their applicability under changed conditions. The adoption
of SFAS No.  145 did not  have a  material  effect  on the  Company's  financial
position or results of operations.

In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated with
Exit or Disposal  Activities.  This Statement addresses financial accounting and
reporting for costs  associated  with exit or disposal  activities and nullifies
Emerging  Issues Task Force ("EITF") Issue No. 94-3,  Liability  Recognition for
Certain  Employee  Termination  Benefits  and  Other  Costs to Exit an  Activity
(including  Certain Costs Incurred in a Restructuring).  This Statement requires
that a liability  for a cost  associated  with an exit or  disposal  activity be
recognized  when the  liability  is  incurred  as  opposed  to on the date of an
entity's  commitment to an exit plan, which was the practice employed under EITF
Issue 94-3.  The provisions of this Statement are effective for exit or disposal
activities that are initiated  after December 31, 2002,  with early  application
encouraged.  SFAS 146 is not expected to have a material effect on the Company's
financial position or results of operations.

NOTE 7 - Commitments and Contingencies

On January 25,  2001,  the Company  filed a complaint  in U.S.  District  Court,
Eastern  District  of Texas  (Marshall  Division)  against The  MathWorks,  Inc.
("Defendant")  for patent  infringement.  The Company  claims that the Defendant
infringes  certain of the  Company's  U.S.  patents.  Defendant  challenges  the
validity  and  enforceability  of these  patents  and  asserts  that it does not
infringe  the claims of these  patents.  The  Company  seeks  monetary  damages,
injunction of the sale of certain products of the Defendant, and attorney's fees
and costs. The case was originally set for trial September 4, 2002.  However, on
July 18, 2002,  the court,  due to other  scheduling  considerations,  reset the
trial for January 6, 2003.  As a result of the  rescheduled  trial,  the Company
expects to incur legal expenses of  approximately  $700,000 in the third quarter
of 2002 and approximately $800,000 spread between the fourth quarter of 2002 and
the first  quarter of 2003.  Due to the inherent  uncertainties  of  litigation,
there can be no  assurance  that  there will not be  significant  changes in the
amount and timing of these expected expenses.

     Net Sales.  Consolidated  net sales decreased by $4.2 million or 4% for the
three  months ended June 30, 2002 to $93.5  million  from $97.7  million for the
three months ended June 30, 2001,  and  decreased  $17.5 million or 9% to $188.2
million  for the six months  ended June 30,  2002 from  $205.8  million  for the
comparable period in the prior year. The decrease in sales for the three and six
months  ended  June  30,  2002  was  primarily  attributable  to the 18% and 27%
declines,  respectively, in the sales of certain hardware products that are used
to control traditional instruments,  which resulted from the continued worsening
of the industrial  economy and the severe  deterioration of sales of traditional
instruments by other vendors used in test and measurement  applications.  In the
quarter  ended June 30, 2002,  the sales of hardware  products  that are used to
control  traditional  instruments  represented 19% of revenue compared to 22% in
the quarter  ended June 30, 2001.  For the six months  ended June 30, 2002,  the
sales of  hardware  products  that are used to control  traditional  instruments
represented 19% of revenue compared to 24% for the comparable prior year period.



     Sales in the  Americas in the second  quarter of 2002  decreased by 2% from
the second  quarter of 2001 and sales in the  Americas  for the six months ended
June 30, 2002 decreased 9% from the six months ended June 30, 2001.

     Sales outside of North America,  as a percentage of consolidated  sales for
the quarter ended June 30, 2002,  decreased to 47% from 48% over the  comparable
2001  period as a result of weaker  sales in  Europe.  International  sales as a
percentage of consolidated sales for the six months ended June 30, 2002 remained
flat  at  48%  compared  with  the  comparable  2001  period.  Compared  to  the
corresponding  periods in 2001, the Company's European sales decreased by 12% to
$29.4  million for the quarter ended June 30, 2002 and decreased by 13% to $58.4
million for the six months ended June 30, 2002. Sales in Asia Pacific  increased
by 8% to $14.6  million in the quarter  ended June 30, 2002 compared to the same
period in 2001 and  increased 3% to $32.7  million for the six months ended June
30, 2002 compared to the same period in 2001. 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 weighted  average value of the U.S.
dollar.  This weighted  average is calculated  as the  percentage  change in the
value of the currency relative to the U.S. dollar,  multiplied by the proportion
of international sales recorded in the particular  currency.  Between the second
quarter of 2001 and the second  quarter of 2002 the  weighted  value of the U.S.
dollar  decreased by 2.2%,  causing an  equivalent  increase in the U.S.  dollar
value of the Company's  foreign  currency  sales and  expenses.  If the weighted
average value of the U.S. dollar in the second quarter of 2002 had been the same
as that in the second quarter of 2001, on a pro-forma  basis the Company's sales
for the second  quarter of 2002 would have decreased by 4%.  Pro-forma  European
sales for the second quarter of 2002 would have decreased by 10% over the second
quarter 2001.  Pro-forma Asia Pacific sales for the second quarter of 2002 would
have increased by 5% over the second quarter 2001 sales. If the weighted average
value of the dollar in the six months  ended June 30,  2002 had been the same as
that in the six months ended June 30, 2001,  on a pro-forma  basis the Company's
year-to-date  sales would have  decreased  by 9% over 2001  year-to-date  sales.
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  $1.6  million  for the six months  ended June 30,  2002 and
$200,000 for the quarter ended June 30, 2002.

     Gross Profit. As a percentage of net sales, gross profit decreased to 71.5%
for the second  quarter  of 2002 from  73.8% for the second  quarter of 2001 and
decreased  to  72.4%  for the  first  six  months  of 2002  from  74.5%  for the
comparable  period a year  ago.  Approximately  60% of the  lower  margin in the
second quarter of 2002 is attributable  to the impact of fixed charges  relative
to  lower  sales  volume.   The  remaining  fraction  of  the  lower  margin  is
attributable  to reduced  sales of certain  hardware  products  that are used to
control traditional instruments. There can be no assurance that the Company will
maintain its historical margins.

     The Company  established a new  manufacturing  facility in Hungary in 2001.
The  Company  believes  its current  manufacturing  capacity is adequate to meet
current needs.



     Sales and Marketing. Sales and marketing expenses for the second quarter of
2002  decreased  to $33.6  million,  an 8%  decrease,  as compared to the second
quarter of 2001 and  decreased  8% to $69.0  million for the first six months of
2002 from the comparable  2001 period.  As a percentage of net sales,  sales and
marketing expenses were 35.9% and 37.2% for the three months ended June 30, 2002
and 2001,  respectively,  and 36.7% and 36.4% for the six months  ended June 30,
2002 and 2001, respectively.  The decreases in these expenses is attributable to
decreases in advertising and literature costs,  training 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  decreased to
$15.7  million for the quarter ended June 30, 2002, a 1% decrease as compared to
$15.9  million for the three  months ended June 30,  2001,  and  increased 2% to
$31.7  million for the six months ended June 30, 2002 from the  comparable  2001
period.  As a  percentage  of  net  sales,  research  and  development  expenses
increased  to 16.8% for the  quarter  ended  June 30,  2002,  from 16.3% for the
quarter  ended June 30,  2001,  and  increased to 16.8% for the six months ended
June 30,  2002,  from 15.1% for the  comparable  2001  period.  The  increase in
research  and  development  costs in the six month  period  ended June 30,  2002
versus the prior year  period and as a  percentage  of sales in each  period was
primarily due to increases in personnel costs from hiring of additional  product
development engineers.  Research and development personnel increased from 693 at
June 30, 2001 to 758 at June 30, 2002.  The Company  plans to continue  making a
significant   investment  in  research  and   development  in  order  to  remain
competitive and continue revenue growth.

     The Company capitalizes  software  development costs in accordance with the
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 $1.1 million and $756,000 for the quarters ended June 30, 2002 and 2001,
respectively, and $1.9 million and $1.5 million during the six months ended June
30, 2002 and 2001,  respectively.  Software  development  costs capitalized were
$1.2  million  and  $933,000  for the  quarters  ended  June 30,  2002 and 2001,
respectively, and $1.6 million and $2.0 million for the first six months of 2002
and 2001, respectively.

     General and  Administrative.  General and  administrative  expenses for the
second  quarter  ended June 30, 2002  increased  15% to $8.8  million  from $7.7
million for the comparable prior year period.  For the first six months of 2002,
general and  administrative  expenses  increased 8% to $16.6  million from $15.4
million for the first six months of 2001. As a percentage of net sales,  general
and  administrative  expenses  increased to 9.4% for the quarter  ended June 30,
2002 from 7.9% for the second  quarter  of 2001.  During the first six months of
2002, general and administrative  expenses increased as a percentage of sales to
8.8% from 7.5% for the comparable prior year period.  The Company's  general and
administrative  expenses increased due to litigation costs of approximately $1.3
million associated with a legal action by the Company brought against MathWorks,
Inc. in 2001 to enforce our intellectual property. (See Note 7 - Commitments and
Contingencies.) 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 second  quarter of 2002
decreased  to  $839,000  from $1.5  million in the second  quarter of 2001,  and
decreased to $1.6 million for the first six months of 2002 from $3.3 million for
the comparable  2001 period.  Net interest income has  historically  represented
less than two percent of revenue and has  fluctuated  as a result of  investment
balances,  bank borrowings and interest terms thereon.  The decrease in interest
income  for the  quarter  and six months  ended  June 30,  2002 was due to lower
yields on the Company's  investments.  The primary source of interest  income is
from the investment of the Company's cash and short-term investments.

     Net Foreign  Exchange  Gain  (Loss).  The Company  experienced  net foreign
exchange  gains of $217,000 in the second  quarter of 2002  compared to gains of
$116,000 in the second quarter of 2001. Net foreign  exchange losses of $677,000
were  recognized  for the first six  months of 2002  compared  to losses of $1.3
million  for the first six months of 2001.  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  increase in net foreign
exchange  gains in the second  quarter of 2002 and the  decrease  in net foreign
exchange  losses  recognized in the six months ended June 30, 2002 is mainly due
to the weakening of the U.S. dollar.



     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 and the yen) and limits the duration of these  contracts to
30 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 $3.5 million during the quarter
ended June 30, 2002, and by $1.0 million for the six months ended June 30, 2002.

     Provision  for Income Taxes.  The  provision  for income taxes  reflects an
effective  tax rate of 28% for the three and six months  ended June 30, 2002 and
32% for the three and six  months  ended  June 30,  2001.  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.  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 June 30,  2002,  the Company had working
capital of  approximately  $218.7 million compared to $209.8 million at December
31, 2001.  Net cash  provided by operating  activities  for the six months ended
June 30, 2002 totaled $21.5 million.

     Accounts receivable  increased to $59.7 million at June 30, 2002 from $53.6
million at December 31, 2001. Days sales outstanding increased to 58 at June 30,
2002  compared to 51 at  December  31,  2001.  Consolidated  inventory  balances
decreased to $32.5  million at June 30, 2002 from $32.6  million at December 31,
2001.  Inventory  turns remained flat at 3.3 for the quarter ended June 30, 2002
versus the quarter ended December 31, 2001. Cash used in the first six months of
2002 for the purchase of property and  equipment  totaled $15.6 million and $1.6
million was used for the capitalization of software development costs.

     In October of 2000, the Company began  construction  of an office  building
("Mopac C") located on the North Austin campus. Construction costs have been and
will  continue to be paid out of the Company's  existing  working  capital.  The
Company  estimates  the total cost for the new  building,  including  furniture,
fixtures and  equipment,  will be  approximately  $59  million.  The Company has
incurred  approximately $52.0 million in construction costs as of June 30, 2002,
with the remainder  becoming payable over the next six months.  The actual level
of spending  may vary  depending on a variety of factors,  including  unforeseen
difficulties  in  construction.  Upon  completion  of the Mopac C building,  the
Company  intends  to vacate  its  existing  136,000  sq.  ft.  Millenium  office
building.  The Company had previously signed an agreement to lease the Millenium
building to a third party tenant, Trilogy Software,  Inc. ("Trilogy") of Austin,
Texas. On July 18, 2002, Trilogy, citing economic hardship, tendered a letter to
the Company  purporting to surrender all rights to the Millenium office building
lease,  indicating its intention not to make any lease payments after July 2002,
and  offering to buy-out its  remaining  obligations  on the lease.  At present,
Trilogy  has failed to make  timely  payment of rent due for August  2002 and is
currently in default of the lease terms. The Company has not accepted  Trilogy's
surrender of the  premises  and has  indicated to Trilogy its intent to strictly
enforce the terms of the lease.  Although the Company and Trilogy are  currently
discussing  terms of a possible  buy-out,  there can be no  assurance  as to the
timing or amount of payment the Company may receive from Trilogy, if any.

     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 June 30, 2002, the Company had no debt outstanding.

     The Company believes that the 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.  As has occurred
in the past,  most recently in the quarter ended March 31, 2002,  these dynamics
have adversely affected revenue growth in international  markets.  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 inventory 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 June 30, 2002, the
Company has  outstanding  guarantees  for payment of foreign  operating  leases,
customs and foreign  grants  totaling  approximately  $3.3 million.  At June 30,
2002,  the  Company  did not have  any  relationships  with  any  unconsolidated
entities  or  financial  partnerships,  such as  entities  often  referred to as
structured   finance  or  special  purpose  entities,   which  would  have  been
established for the purpose of facilitating  off-balance  sheet  arrangements or
other  contractually  narrow or limited  purposes.  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 exchanges rates on its results of operations and financial position.
Based on the foreign  exchange  instruments  outstanding  at June 30,  2002,  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  $8.7  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 June  30,  2002  was  $99.0  million.  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 June
30, 2002, a 100 basis point  increase or decrease in interest rates would result
in a decrease or increase of approximately $675,000,  respectively,  in the fair
value of the investment  portfolio,  which is not  significantly  different from
December 31, 2001.  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.

Non-Audit  Services

     Prior to adoption of the  Sarbanes-Oxley  Act of 2002, the Company's  Audit
Committee  modified its charter to pre-approve the following  non-audit services
(not  to  exceed  $150,000  in  the  aggregate  per  year):   tax  research  and
consultations;  international  tax consulting;  tax assistance and compliance in
international  locations;  assistance  with  transfer  pricing;  expatriate  tax
services;  consultations  and assistance  with other taxes  including  state and
local taxes,  sales and use taxes,  customs and duties;  review of  intercompany
agreements; and assistance with international manufacturing tax issues.

Recently Issued Accounting Pronouncements

     In May 2002,  the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial Accounting Standards ("SFAS") No. 145, Rescission of FASB
Statements No. 4, 44, and 64,  Amendment of FASB Statement No. 13, and Technical
Corrections  as of April 2002.  The  Statement  rescinds SFAS No. 4 and requires
that only unusual or  infrequent  gains and losses from  extinguishment  of debt
should be classified as  extraordinary  items,  consistent  with APB Opinion 30.
This  Statement  amends SFAS No. 13 to  eliminate an  inconsistency  between the
required accounting for sale-leaseback  transactions and the required accounting
for certain lease  modifications  that have economic effects that are similar to
sale-leaseback  transactions.   This  Statement  also  amends  certain  existing
authoritative  pronouncements  to make various  technical  corrections,  clarify
meanings, or describe their applicability under changed conditions. The adoption
of SFAS No.  145 did not have a material  effect on our  financial  position  or
results of operations.

     In June 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated
with Exit or Disposal Activities.  This Statement addresses financial accounting
and  reporting  for  costs  associated  with  exit or  disposal  activities  and
nullifies  Emerging  Issues  Task  Force  ("EITF")  Issue  No.  94-3,  Liability
Recognition for Certain Employee Termination Benefits and Other Costs to Exit an
Activity  (including Certain Costs Incurred in a Restructuring).  This Statement
requires  that a  liability  for a cost  associated  with an  exit  or  disposal
activity be recognized  when the liability is incurred as opposed to on the date
of an entity's commitment to an exit plan, which was the practice employed under
EITF Issue 94-3.  The  provisions  of this  Statement  are effective for exit or
disposal  activities  that are  initiated  after  December 31, 2002,  with early
application  encouraged.  SFAS 146 is not expected to have a material  effect on
the Company's financial position or results of operations.

Factors Affecting the Company's Business and Prospects

     U.S./Global Economic Slowdown. As recently experienced,  when the worsening
of  the  industrial  economy  resulted  in  a  deterioration  of  the  test  and
measurement  market,  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.  Downturns  in 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 the remainder
of 2002.  The  Company's  spending  for the second half 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;
additional  construction  costs and/or delays in the construction of the Mopac C
office  building;  failure of a third party tenant to pay rent for leased office
space and/or  additional  litigation  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 revise
its budget in  response to any  decrease  in our  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's  results of operations in
the third  quarter of 2002 may be  adversely  affected by lower sales  levels in
Europe, which typically occur during the summer months. 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 significantly 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  in part 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
assurance  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.

     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 export regulations.  Failure to comply
with  these  regulations  could  result in fines  and/or  termination  of export
licenses,  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  weighted  average  value of the  U.S.  dollar.  This  weighted  average  is
calculated as the percentage change in the value of the currency relative to the
dollar,  multiplied by the  proportion of  international  sales  recorded in the
particular  currency.  Between the second quarter of 2002 and the second quarter
of 2001  this  weighted  average  value of the U.S.  dollar  decreased  by 2.2%,
causing an equivalent increase in the U.S. dollar value of the Company's foreign
currency  sales and  expenses.  If the weighted  average value during the second
quarter  of 2002 had been the same as that in the second  quarter of 2001,  on a
pro-forma  basis the Company's  sales for the second  quarter of 2002 would have
decreased by 4%. If the weighted average value during the second quarter of 2002
had been the same as that in the second  quarter of 2001,  on a pro-forma  basis
the Company's  consolidated operating expenses would have been $58.0 million. If
the U.S.  dollar  strengthens  in the future,  it could have a material  adverse
effect on the operating results of the Company.



     As of June 30, 2002,  the Company has $3.0 million of deferred gains on yen
foreign  currency  cash flow  hedge  contracts  recorded  in  accumulated  other
comprehensive income that are expected to be reclassified into earnings over the
next 18 months.  If the yen fails to strengthen  before the  expiration of these
contracts,  and if the  Company  is unable to  increase  prices in Japan  and/or
globally,  the Company will experience a deterioration  of revenue and gross and
net profit margins,  which could have a material 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.  The  Company
estimates that by 2003,  this facility will source a significant  portion of the
Company's  sales.  Currently  the Company is continuing to recruit and train the
local work force and 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 results of
operations.

     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  through  2011.  These  benefits  may not be
available in the future due to changes in Hungary's  political  condition and/or
tax laws.  Specifically,  Hungary has applied for  inclusion  into the  European
Union.  In order for Hungary to gain  acceptance  into the European  Union,  the
Hungarian  government may choose to change  existing tax laws which could result
in the reduction or  elimination  of these foreign  investment  incentives.  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 results of operations.

     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 ETI has been ruled an illegal export subsidy by the World Trade Organization.
Legislation has been introduced in Congress that would repeal ETI as of December
31, 2002. The repeal of 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 results of operations.

     Products  Dependent  on Certain  Industries.  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 2001,  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 results of operations.

     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 results of operations.

     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,  Accounting  for  Stock-Based  Compensation,  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,  the Company  estimates  it would have  recognized  stock
option  expense of  approximately  $73,000 and  $340,000 for the quarter and six
month periods  ended June 30, 2002. If the Company were to adopt the  accounting
provision of SFAS No. 123, the adoption would be prospective.  Accordingly,  the
Company  would  expect  stock  option  expense  to  increase  in the  future  if
additional stock options are issued.



     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 is currently litigating a complaint in
federal court alleging patent infringement by the products of a defendant. 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 this  litigation  or any other  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 results of operations.

     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 effect on operating  results.  The Company also believes its
future  success will depend in large part 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, including companies acquired through acquisition, as
well as training,  motivating and  supervising the 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  to the  current  degree.  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 results of operations.

     Risk of Product  Liability Claims.  The Company's  products are designed in
part 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.



                           PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

     On January 25, 2001, the Company filed a complaint in U.S.  District Court,
Eastern  District  of Texas  (Marshall  Division)  against The  MathWorks,  Inc.
("Defendant")  for patent  infringement.  The Company  claims that the Defendant
infringes  certain of the  Company's  U.S.  patents.  Defendant  challenges  the
validity  and  enforceability  of these  patents  and  asserts  that it does not
infringe  the claims of these  patents.  The  Company  seeks  monetary  damages,
injunction of the sale of certain products of the Defendant, and attorney's fees
and costs. The case was originally set for trial September 4, 2002.  However, on
July 18, 2002,  the court,  due to other  scheduling  considerations,  reset the
trial for January 6, 2003.  As a result of the  rescheduled  trial,  the Company
expects to incur legal expenses of  approximately  $700,000 in the third quarter
of 2002 and approximately $800,000 spread between the fourth quarter of 2002 and
the first  quarter of 2003.  Due to the inherent  uncertainties  of  litigation,
there can be no  assurance  that  there will not be  significant  changes in the
amount and timing of these expected expenses.

           December 31, 2002.

     The foregoing  matters are described in detail in the Company's  definitive
proxy statement dated April 4, 2002, for the Annual Meeting of Stockholders held
on May 14, 2002.



ITEM 5.  OTHER INFORMATION

     Pursuant to the Company's  Bylaws,  stockholders  of the Company may submit
proper  proposals  for  inclusion  in the  Company's  proxy  statement  and  for
consideration  at the next annual meeting of  stockholders  by submitting  their
proposals  in writing to the  Secretary  of the Company in a timely  manner.  In
order to be considered  for inclusion in the Company's  proxy  materials for the
annual  meeting  of  stockholders  to be  held  in the  year  2003,  stockholder
proposals  must be  received  by the  Secretary  of the  Company  no later  than
December 5, 2002, and must otherwise  comply with the requirements of Rule 14a-8
of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

     In addition,  the Company's  bylaws  establish an advance notice  procedure
with regard to business brought before an annual meeting,  including stockholder
proposals  not  included  in  the  Company's  proxy   statement.   For  director
nominations  or other  business  to be properly  brought  before the 2003 Annual
Meeting by a stockholder,  such  stockholder  must deliver written notice to the
Secretary of the Company at the Company's  principal  executive  office no later
than  February 3, 2003 and no earlier than  January 4, 2003.  If the date of the
Company's  2003  Annual  Meeting is advanced or delayed by more than 30 calendar
days from the first anniversary date of the 2002 Annual Meeting,  your notice of
a  proposal  will be timely if it is  received  by the  Company  by the close of
business on the tenth day following the day the Company  publicly  announces the
date of the 2003 Annual Meeting.

     The  proxies  solicited  by the Company  each year grant the proxy  holders
discretionary  authority to vote on any matter  raised at the  Company's  annual
meeting.  If a stockholder fails to comply with the foregoing notice provisions,
proxy holders will be allowed to use their discretionary voting authority should
the stockholder proposal come before the 2003 Annual Meeting.

     A copy of the  full  text of the  bylaw  provisions  governing  the  notice
requirements  set forth above may be obtained by writing to the Secretary of the
Company.  All notices of proposals  and  director  nominations  by  stockholders
