ITEM 1.   BUSINESS

     National Instruments  Corporation (the "Company" or "National Instruments")
is a leading supplier of measurement and automation  products that engineers and
scientists use in a wide range of industries. These industries are spread across
a large and  diverse  market for test and  measurement  ("T&M")  and  industrial
automation  ("IA")  applications.  The  Company  provides  flexible  application
software  and  modular,   multifunction   hardware   that  users   combine  with
industry-standard computers, networks and the Internet to create measurement and
automation systems, which the Company also refers to as "virtual instruments."

     A virtual  instrument is a user-defined  measurement and automation  system
that consists of an industry standard computer or workstation  equipped with the
Company's user-friendly application software, cost-effective hardware and driver
software.   Virtual   instrumentation   represents  a  fundamental   shift  from
traditional  hardware-centered   instrumentation  systems  to  software-centered
systems that exploit the computational,  display,  productivity and connectivity
capabilities   of  computers,   networks  and  the  Internet.   Because  virtual
instruments exploit these computation,  connectivity,  and display capabilities,
users can define and change the functionality of their instruments,  rather than
being restricted by fixed-functions  imposed by traditional  instrument vendors.
The  Company's  products  empower  users  to  monitor  and  control  traditional
instruments,   create  innovative   computer-based   systems  that  can  replace
traditional  instruments  at a lower cost,  and develop  systems that  integrate
measurement functionality with industrial automation.  The Company believes that
giving users  flexibility to create their own user-defined  virtual  instruments
for an increasing  number of applications  in a wide variety of industries,  and
letting users leverage the latest  technologies  from computers,  networking and
communications  shortens  system  development  time and reduces  both short- and
long-term costs of developing,  owning and operating  measurement and automation
systems,  and  improves  efficiency  and  precision  of  applications   spanning
research, design, production and service.

     The Company is based in Austin,  Texas and was incorporated  under the laws
of the State of Texas in May 1976 and was  reincorporated  in  Delaware  in June
1994. On March 13, 1995,  the Company  completed an initial  public  offering of
shares of its Common Stock.  The Company's  Common  Stock,  $0.01 par value,  is
quoted on the NASDAQ National Market System under the trading symbol NATI.


     Industry Background

     Engineers and  scientists  have long used  instruments  to observe,  better
understand and manage the real-world phenomena,  events and processes related to
their  industries  or  areas  of  expertise.  Instruments  measure  and  control
electrical signals, such as voltage,  current and power, and physical phenomena,
such as temperature, pressure, speed, flow, volume, torque and vibration. Common
instruments include voltmeters, signal generators,  oscilloscopes,  dataloggers,
spectrum  analyzers,   cameras,   and  temperature  and  pressure  monitors  and
controllers.   Instruments   generally  perform  three  basic  functions:   data
acquisition and control; data analysis; and presentation of results. Instruments
are  used  pervasively  in  research,   education,   manufacturing  and  service
applications in numerous fields including  electronics,  automotive,  aerospace,
telecommunications,  medical  research  and  pharmaceutical,  semiconductor  and
petrochemical.

     Instruments and systems are used to facilitate  research as well as product
design, production and service. In research and development settings, scientists
and engineers use  instruments  and systems to collect and analyze  experimental
data and  simulate  manufacturing  processes  or  techniques.  In  manufacturing
environments,  engineers  use  instruments  and  systems  to test and verify the
proper  operation of the products being  manufactured and to monitor and control
the manufacturing machines and processes.  In service contexts,  instruments and
systems are used to monitor, troubleshoot and repair products and processes.


     Traditional Instrument Applications for Measurement and Automation

     Instrument  applications can be generally  categorized as either T&M or IA.
T&M applications  generally  involve testing during the design,  manufacture and
service  of a wide  variety  of  products.  IA  applications  generally  involve
automating the machinery and processes  used in the production and  distribution
of a wide variety of products and materials.

                                      -2-


     A typical T&M instrument is a stand-alone  unit that has input,  output and
analysis capabilities;  knobs, switches and push buttons for user operation; and
gauges,  meters or other displays for visual data  presentation.  Traditionally,
most T&M instruments  were  vendor-defined,  fixed-function  devices designed to
address specific  applications.  As a result,  users had limited  flexibility to
adapt their instruments to changing  requirements.  In the 1960's, vendors began
to incorporate integrated circuits, including programmable microcontrollers,  to
increase  instrument  flexibility.   In  the  mid-1970's,  the  General  Purpose
Interface  Bus ("GPIB" or "IEEE 488") was  developed as a standard  interface to
connect  instruments to external computers.  The first computer  controllers for
GPIB instruments were based on proprietary hardware architectures.  In the later
1970's,  some  minicomputers  with general purpose but complex operating systems
were  equipped  for GPIB  instrument  control.  In the  early  1980's,  personal
computers  with limited  processing  power  equipped  with  MS-DOS,  a standard,
character-based operating system, began replacing minicomputers as the preferred
platforms for instrument control applications.  In the 1990s, personal computers
with Windows operating systems and graphics-based  application  software grew in
popularity   and  became  the  dominant   platforms   for   instrument   control
applications.  In the late 1990s,  connectivity  to the Internet and the ability
for personal  computers to integrate and share data  throughout  the  enterprise
further  increased the popularity and use of PC-based  instrumentation  systems,
and new web-enabled tools enabled users to begin to easily leverage the internet
for networked and distributed measurement applications.

     IA systems have long included mechanical devices, analog gauges and meters,
and since the 1960's,  have also included  electronic  instruments  such as data
loggers and strip chart recorders. In the 1970's, programmable logic controllers
("PLCs"),  special-purpose,  proprietary stand-alone industrial computers,  were
introduced  and were used primarily for  "discrete"  manufacturing  applications
such as automobile  assembly.  PLCs have  traditionally  had primitive  operator
interface  panels  incorporating  buttons,  lights and indicators.  In parallel,
sophisticated   instrumentation   systems  called  distributed  control  systems
("DCSs") were also adopted to provide computer control of large-scale continuous
processes,  such as those found in oil refineries.  DCSs integrated a variety of
sensors and control  elements  using both  analog and digital  connections,  all
controlled  by  a  central  computer  running  proprietary   software.   In  the
mid-1980's,  another  approach  became  available  when  industrial  PC-based IA
systems came into use. These early PC-based  systems  generally ran proprietary,
vendor-defined  software and  incorporated  plug-in data  acquisition  boards or
interfaced  to PLCs.  In the 1990's,  Ethernet  networks grew in popularity as a
standard for  connectivity  between IA devices,  instruments,  and systems,  and
personal  computers with high-speed  processors  running Windows based operating
systems. In addition,  graphics-based application software grew in popularity as
platforms for supervision and control of IA systems and  applications.  Finally,
just as in T&M  applications,  in the late 1990's  connectivity  to the internet
enabled users to leverage networked applications via the internet.


     Limitations of Traditional Approaches to Instrumentation

     Instruments and systems for both T&M and IA applications  have historically
shared  common  limitations,  including:  fixed,  vendor-defined  functionality;
proprietary,  closed  architectures that were generally difficult to program and
integrate  with other  systems;  and inflexible  operator  interfaces  that were
usually  cumbersome  to operate and change.  These  problems  have been  further
complicated  in  IA   applications   because   specialized   data  transfer  and
communications  standards have not evolved rapidly or been widely  adopted.  For
example, PLCs, while greatly improving control of individual processes,  created
multiple  "islands of information"  that were generally unable to communicate or
share  data  with  other  systems   throughout  the  manufacturing   enterprise.
Furthermore,  proprietary  instrumentation  systems have traditionally been very
expensive,  with IA system prices ranging as high as several million dollars and
T&M instrumentation  system prices often ranging in the hundreds of thousands of
dollars. In addition,  the limitations on programmability of traditional systems
means that adopting these systems to changing requirements is both expensive and
time consuming, and users are often required to purchase multiple single-purpose
instruments.

     Although  desktop  computers  in the  1980's  typically  were based on open
architectures,  until the 1990's they lacked higher-level  application  software
development   tools  and   intuitive   graphical   user   interfaces   ("GUIs").
Consequently,  the process of creating  intuitive operator interface and control
panels was difficult and  expensive.  These early desktop  computers also lacked
the power to rapidly  process and analyze the volume of data  characteristic  of
many high data rate T&M and IA applications. In addition, desktop computers were
difficult to network reliably until standard network  operating  systems evolved
late in the decade. For all of these reasons,  users and vendors were relatively
slow to incorporate desktop computers in their instrumentation systems.

                                      -3-


     In the 1990's,  desktop and portable  computers  improved  significantly in
data and graphics  processing  power,  storage,  communication,  and  networking
capabilities,  user-friendliness and reliability. Nevertheless, users accustomed
to  the  flexibility,   efficiency,   power  and  open   architecture  of  these
later-generation   computers,   and  the  highly  evolved  application  software
available for business computing needs, have been generally  frustrated in their
efforts to integrate these computers into measurement and automation  solutions.
Standard  desktop  computers  were not equipped  with the  hardware  connections
required    to    control    many    types    of    instruments    and    lacked
instrumentation-specific    application   development   tools,   including   GUI
development environments.  Neither standard programming languages such as C/ C++
and Visual Basic,  nor operating  systems such as Windows,  Linux and UNIX,  are
"measurement  aware."  Without the aid of  instrumentation-specific  software to
facilitate the integration of various  instrumentation  system  capabilities and
components, engineers and scientists could not easily utilize the full potential
of computers, networks and the Internet to meet their measurement and automation
requirements.


     The Company's Approach to Measurement and Automation

     The Company  pioneered a new  computer-based  approach to  measurement  and
automation called virtual instrumentation in 1986 when it introduced its LabVIEW
application software, which is a graphical programming environment that empowers
users to easily build their own  computer-based  instruments and systems to meet
their specific measurement and automation needs. While a traditional  instrument
bundles the data acquisition,  analysis and presentation  functions in a single,
stand-alone  unit, a "virtual  instrument"  system consists of industry standard
computers or workstations equipped with the Company's user-friendly  application
software,  cost-effective hardware and driver software that together perform the
functions of  instruments.  By  unbundling  the key  instrumentation  functions,
virtual  instruments  represent  a  fundamental  shift  from   hardware-centered
instrumentation   systems  to   software-centered   systems   that  exploit  the
computational, display, productivity and connectivity capabilities of computers,
networks and the Internet.  The  Company's  application  software  products give
users the power and  flexibility  to define,  implement,  modify and control the
core data acquisition,  analysis, and presentation functions of instruments with
their computer. Users can mix and match their choice of the Company's DAQ, GPIB,
VXI,  PXI,  image  acquisition,  motion  control  or  industrial  communications
products to create  virtual  instrumentation  systems  that meet their  specific
instrumentation  needs.  The  Company's  products  empower  users to monitor and
control instruments,  create innovative  computer-based systems that can replace
instruments  at a lower  cost,  and  integrate  measurement  functionality  with
industrial  automation and standard network  connectivity to improve  efficiency
and precision of applications spanning research, design, production and service.
Because much of the instrumentation  functionality resides in the software, in a
significant sense, the software is the instrument.


     User Benefits

     Compared with traditional solutions,  the Company believes its products and
computer-based,   virtual   instrumentation   approach   provide  the  following
significant customer benefits:


     Performance, Ease-of-Use and Efficiency

     The Company's virtual instrument  application software brings the power and
ease-of-use  of  computers,  networks  and the  Internet to the  instrumentation
market. With features such as graphical  programming,  automatic code generation
capabilities,  graphical  tools  libraries,  ready-to-use  example  programs and
libraries  of specific  instrumentation  functions,  users can  quickly  build a
virtual  instrument  system that meets their individual  application  needs. For
example,  a user may build the data  acquisition  and  analysis  functions of an
instrument   by  selecting  and   connecting   icons   representing   particular
instrumentation  functions  and may  customize  the  display  on the  computer's
monitor to reflect the desired presentation. With faster time to solution, users
have more time to optimize system functionality and performance,  and can devote
more  time to  their  core  work  rather  than to  programming  instruments.  In
addition,  the  continuous  improvement  in performance of PCs and the Internet,
which  are the core  platform  for the  Company's  approach,  result  in  direct
performance  benefits  for  virtual  instrument  users  in the  form  of  faster
execution for software-based measurement and automation applications,  resulting
in  shorter  test  times  and  faster  automation,   and  higher   manufacturing
throughput.


     Modularity, Reusability and Reconfigurability

     The Company's  products include reusable hardware and software modules that
offer considerable flexibility in configuring systems. This ability to reuse and
reconfigure  instrument  systems  allows  users to reduce  development  time and
maximize efficiency by eliminating duplicated programming efforts and to quickly
adapt their  instruments to new and changing needs. In addition,  these features
help protect both hardware and software investments against obsolescence.

                                      -4-


     Mix and Match Capabilities

     The flexibility of the Company's virtual  instrumentation  approach permits

processors,  spreadsheets,  Web browsers, and databases. In many cases, a single
computer or workstation can serve both the  instrumentation  and general purpose
computing needs of scientists and engineers.


     Large User Base

     The Company supports and encourages the sharing of ideas,  derived software
libraries  and  modules  among its broad user base  through its NI.com Web site,
user groups,  newsletters,  conferences  and seminars.  This large base of users
stimulates  the expansion of the Company's  network of  approximately  600 third
party system  integrators and consultants,  who can save users time and money by
providing  value-added  expertise,  software programs and integration of systems
for use with the Company's products.


     Lower Total Solution Cost

     The   Company    believes   that   its   products   and   solutions   offer
price/performance   advantages   over   traditional   instrumentation.   Virtual
instrumentation   provides  users  the  ability  to  utilize  industry  standard
computers  and  workstations  equipped  with  modular and  reusable  application
software,  cost-effective hardware and driver software that together perform the
instrumentation   functions  that  would   otherwise  be  performed  by  costly,
proprietary  instrumentation systems. In addition, virtual instrumentation gives
users the  flexibility  and  portability  to adapt to  changing  needs,  whereas
traditional  closed systems are both  expensive and time consuming to adapt,  if
adaptable at all.

     Develop and Support Industry Standards.  The Company actively  participates
in  efforts  to  standardize  key  technologies  by  participating  in  industry
consortia and serving on standards  committees,  such as IEEE 488, VXI,  Compact
PCI, PXI, PICmg, the Interchangeable  Virtual Instrumentation  Foundation,  also
called IVI, Foundation  Fieldbus,  OPC, and ASAM. The Company's ongoing strategy
is to conform its products to  established  and  emerging  standards in both the
general computer and the instrumentation industries.


     Products and Technology

     The  Company  offers  an  extensive  line  of  measurement  and  automation
products.  Engineers,  scientists  and  other  users  involved  in  T&M  and  IA
applications can use these products with computers, networks and the Internet to
develop  customer-defined  virtual instrument solutions.  The Company's products
consist of application  software,  and hardware components together with related
driver  software.  In T&M  applications,  the Company's  products can be used to
monitor  and  control  traditional   instruments  or  to  create  computer-based
instruments  that can replace the traditional  instruments.  In IA applications,
the  Company's  products  can be used in the same ways as in T&M and can also be
used  to   integrate   measurement   functionality   with   process   automation
capabilities.  The  Company's  products  are  designed  to  work  either  in  an
integrated  solution or separately.  The Company  believes that the flexibility,
functionality and ease of use of its application  software promotes sales of the
Company's other software and hardware products.


     Application Software

     The Company believes that  application  software is playing an increasingly
important role in the development of  computer-based  instruments and systems in
measurement  and automation  applications.  The Company's  application  software
products  leverage the  increasing  capability  of  computers,  networks and the
Internet  for  data  analysis,  connectivity  and  presentation  power  to bring
increasing efficiency and precision to measurement and automation  applications.
The Company's application software products include LabVIEW, Measurement Studio,
TestStand,  Lookout,  Measure, Virtual Bench, DIAdem, DASYLab, and Vilogger. The
Company's  application  software  products  are  integrated  with the  Company's
hardware/driver software.

     The  Company   offers  a  variety  of  software   products  for  developing
measurement and automation  applications  to meet the different  programming and
computer  preferences  of its  customers.  LabVIEW  and  Measurement  Studio are
programming  environments with which users can develop GUIs, control instruments
and acquire,  analyze and present data. With these software products,  users can
design  custom  virtual  instruments  by creating a GUI on the  computer  screen
through  which they operate the actual  program and control  selected  hardware.
Users can  customize  front  panels  with  knobs,  buttons,  dials and graphs to
emulate  control  panels of  instruments  or add  custom  graphics  to  visually
represent the control and operation of processes. LabVIEW and Measurement Studio
also have  ready-to-use  libraries  for  controlling  hundreds  of  programmable
instruments,  including  serial,  GPIB and VXI, the Company's plug-in DAQ boards
and PXI/PCI computer-based instruments. Once created, virtual instruments can be
modified or used as components of another  program by the original  developer or
another user.

     The principal  difference  between LabVIEW and Measurement Studio is in the
way users develop programs. With LabVIEW, users program graphically,  developing
application  programs by connecting  icons to create "block  diagrams" which are
natural design notations for scientists and engineers.  With Measurement Studio,
users may program with the conventional,  text-based  language of C. Measurement
Studio also includes  application-specific OLE or ActiveX controls and libraries
to the  Microsoft  Visual  Basic,  Visual  C++ and  Borland  Delphi  development
environments.

     The latest  revisions of LabVIEW and Measurement  Studio software  packages
feature  enhanced  capabilities to allow users to more easily  integrate the Web
into their computer-based instrumentation applications.  Measurement Studio 6.0,
a major  upgrade,  was  introduced in 2001.  LabVIEW 6i, which was introduced in
2000, allows the customer to easily  communicate,  share and control measurement
and automation systems and information with anyone on the Web, and customers can
use  the  Internet  and  Intranets  to  build  distributed,   networked  systems
throughout their enterprise. In 2000, the Company also expanded the capabilities
of its LabVIEW  Real Time  software  product to include  support for the PXI and
FieldPoint  hardware  platform  to allow  users  who have  exceptional  response
requirements to reliably execute an expanded range of system-level  applications
even if the PC operating system  crashes--solving a key objection some potential
users have had in the past to using PC  technology  for embedded  devices or for
mission  critical  measurement  and automation  applications,  and extending the
range of applications for computer-based measurement and automation.

                                      -7-


     The Company also sells a range of optional  add-on products for LabVIEW and
Measurement  Studio,  such as advanced  analysis  libraries,  database tools and
Internet integration,  including the LabVIEW Datalogging and Supervisory Control
Module,  an add-on  module for high channel count  applications  in research and
development and manufacturing.

     The Company also offers a software  product called  TestStand  targeted for
T&M applications in a manufacturing environment.  TestStand is a test management
environment for organizing,  controlling,  and running automated production test
systems on the factory  floor.  It also  generates  customized  test reports and
integrates product and test data across the customers' enterprise and across the
Internet.  TestStand  manages tests that are written in LabVIEW and  Measurement
Studio,  C and C++,  and  VisualBasic,  so test  engineers  can easily share and
re-use test code throughout their organization and from one product to the next.
TestStand is a key element of the Company's strategy to broaden the reach of its
application  software  products  across the corporate  enterprise.  In 2001, the
Company  introduced  TestStand 2.0, a significant  upgrade of TestStand for high
volume manufacturing applications. This version allows testing of multiple units
in parallel on the same test system by simply adding additional  measurement and
automation  hardware.  Users can  therefore  easily  scale their test systems to
increase  throughput or reduce test time without major software  changes,  which
lowers the cost to test each unit and increases their profit margin.

     The Company's  instrumentation  software  products also include DASYLab and
DIAdem.  DASYLab is a schematic environment by which users can quickly configure
simple DAQ applications using both the Company's and third-party DAQ boards. The
Company  introduced DASYLab 6.0 in 2001 as well as DIAdem 7.0. DIAdem is an easy
to  use,  rapid  development  environment  for  data  acquisition,   monitoring,
visualization,   open  and  closed  loop  control,   analysis,   automation  and
documentation.   DIAdem  features  extensive  off-line  analysis   capabilities,
including analysis functions specific to automotive test.

     The Company's  Lookout  software  product is targeted  specifically  for IA
applications.  Lookout is a non-programming solution. Lookout is a human machine
interface/supervisory   control  and  data  acquisition  ("HMI/SCADA")  software
product that  requires no  programming  or script  writing.  Lookout  provides a
scalable architecture for applications ranging from HMIs to large, sophisticated
SCADA applications.

     In 2001, the Company  introduced VI Logger, a new software product targeted
specifically  at Data  Logging  applications.  VI Logger is built  with  LabVIEW
technology,  and works with a wide variety of the Company's data acquisition and
signal conditioning hardware products.


     Hardware Products and Related Driver Software

     The Company's  hardware and related driver software  products include GPIB,
VXI, DAQ, PXI, image acquisition, motion control, and industrial communications.
The Company  believes it can deliver  significant  cost/performance  benefits to
users  and  clearly  distinguish  its  products  from  competitive  products  by
designing  proprietary ASICs for use in its hardware products.  Software drivers
are  necessary  to link  hardware  to the  operating  system  and the  Company's
application  software.  The high  level of  integration  between  the  Company's
products  provides  users  with  the  flexibility  to  mix  and  match  hardware
components when developing custom virtual instrumentation systems.

     GPIB Interfaces/Driver Software. GPIB, also known as the IEEE 488 standard,
has existed  since 1975 and defines the protocol for  transferring  data between
certain instruments and computers over an industry-standard  cable. The computer
must be equipped with a GPIB interface.  Driver software  controls the interface
and the  transfer  of data  between the  instrument  and the  computer.  GPIB is
largely used in T&M applications.

     The Company began  selling GPIB products in 1977 and is a leading  supplier
of GPIB  interface  boards  and driver  software  to  control  traditional  GPIB
instruments.  These  traditional  instruments  are  manufactured by a variety of
third-party  vendors and are used primarily in T&M  applications.  The Company's
diverse portfolio of hardware and software products for GPIB instrument  control
is available for a wide range of computers,  workstations and minicomputers. The
Company's GPIB product line also includes  products for portable  computers such
as a PCMCIA-GPIB  interface card, and products for controlling  GPIB instruments
using the computer's  standard  parallel USB, IEEE 1394  (Firewire) and Ethernet
ports.

     Portability  of GPIB  application  programs is  provided  by the  Company's
NI-488.2  driver  software  and NI-VISA  driver  software.  The  Company  offers
networking  capabilities through its GPIB products.  With these products,  users
can  communicate  with  and  control  GPIB  instruments  from  any  point  on an
Ethernet-based TCP/IP network. The Company also offers a variety of GPIB support
products,  including  converters,  expanders,  extenders,  data buffers and GPIB
system analyzers as well as cables and other accessories.

                                      -8-


     VXI  Modules/Driver   Software.   VXI  is  an  industry  standard  high-end
instrumentation  platform  developed in 1987 through an industry  consortium  to
reduce the size and  increase the  performance  of  instrumentation  systems for
automated  test and  measurement  applications.  With VXI, the physical  size of
multiple   instrument  systems  can  be  decreased  and  communication   between
instruments  and  computers  can be  dramatically  improved.  Like GPIB,  VXI is
supported by a variety of traditional  third-party instrument  manufacturers and
is largely used in T&M applications.

     VXI  instruments  are  modular  in  design  and  can be  inserted  into  an
industry-standard  chassis.  Unlike GPIB instruments,  VXI modules do not have a
front  panel for  manual  operation  or  visual  data  presentation.  Therefore,
software  is  necessary  for users to create,  define the  functionality  of and
operate VXI  instrumentation  systems.  Today,  VXI is being used  primarily  to
supplement or replace high-end GPIB products in T&M applications.

     The Company is a leading supplier of VXI computer  controller  hardware and
the accompanying  NI-VXI and NI-VISA driver software.  The Company also offers a
variety of VXI DAQ modules  with  NI-DAQ  driver  software,  as well as LabVIEW,
Measurement Studio and TestStand software products for VXI systems.

     DAQ Hardware/Driver Software. DAQ hardware and driver software products are
"instruments   on  a  board"  that  users  can  combine  with  sensors,   signal
conditioning  hardware and software to acquire analog data and convert it into a
digital  format that can be accepted by a computer.  The Company  believes  that
computer-based DAQ products are typically a lower-cost solution than traditional
instrumentation.

     The  Company  believes  that  applications  suitable  for  automation  with
computer-based DAQ products are widespread throughout many industries,  and that
many systems  currently  using  traditional  instrumentation  (either  manual or
computer-controlled)  could be displaced  by  computer-based  DAQ  systems.  The
Company  offers a range of  computer-based  DAQ products,  including  models for
digital, analog and timing input-output, and for transferring data directly to a
computer's random-access memory.

     The Company's DAQ products  provide a range of  price/performance  options,
and include products for high-speed  applications such as on-line monitoring and
control as well as products designed for long-term  recording of slowly changing
data such as  temperatures.  The Company  also  offers  products  with  features
comparable to stand-alone traditional  instruments such as oscilloscopes,  DMMs,
and  function  and  arbitrary  waveform  generators.   The  Company  offers  DAQ
hardware/driver  software products for numerous desktop and notebook  computers.
The   Company   also   offers   SCXI   (signal   conditioning   extensions   for
instrumentation)  hardware, which expands the types and quantity of sensors that
can be connected to the Company's data acquisition boards.

     PXI Modular Instrumentation. The Company's PXI modular instrument platform,
which was  introduced in 1997, is a desktop PC packaged in a small,  rugged form
factor  with  expansion  slots  and  instrumentation   extensions.  It  combines
mainstream  PC  software  and  PCI  hardware   with   advanced   instrumentation
capabilities  derived  from  the  VXI  architecture.   In  essence,  PXI  is  an
instrumentation  PC with  plenty of  expansion  slots to enable  the  company to
pursue complete system-level  opportunities and deliver a much higher percentage
of the overall  system  content using the  company's own products.  PXI delivers
many of the benefits of VXI in a much smaller  package and at lower prices.  The
Company  continues to expand its PXI product  offerings with new modules,  which
address a wide variety of measurement and automation applications.  In 2001, the
Company  introduced a new 18-slot  chassis which more than doubles the number of
PXI slots that were previously available, and, in addition, introduced a variety
of new measurement  modules,  including an eight channel dynamic signal analyzer
module  for  PXI  that  is  ideal  for  state-of-the-art   sound  and  vibration
measurements,  and a new frequency  domain digitizer that extended the Company's
virtual instrumentation  capabilities to higher frequencies and accuracies.  The
Company  also  introduced  a  new  family  of  embedded  PXI  controllers   that
significantly improve the price and performance of PXI, and upgraded its LabVIEW
Real-Time  software so that the PXI system platform can be used for embedded and
real-time  applications.  PXI  also  continues  to  gain  acceptance  as an open
industry standard, with endorsements from over 50 suppliers.

     Machine Vision/Image Acquisition.  In late 1996, the Company introduced its
first image  acquisition  hardware.  With the advanced  technologies in personal
computers and the Company's vision products,  it is cost-effective for end-users
to integrate  vision into their  measurement  and automation  applications.  The
Company's  vision  software  is designed  to work with many  different  software
environments,  including  LabVIEW,  Visual Basic, C, and Measurement  Studio and
hardware buses  including PCI and PXI.  Vision is commonly used in  applications
ranging  from  quality  control of  manufactured  products  to  biomedical  cell
counting to security. In 2001, the Company expanded its machine vision solutions
with support for IEEE-1394 and Camera Link  cameras,  and new image  acquisition
hardware for PXI.

                                      -9-


     Motion  Control.  During  1997,  the Company  introduced  its first line of
motion control  hardware,  software and peripheral  products.  This  intelligent
PC-based  motion  control  hardware  is  programmable   from  industry  standard
development environments including LabVIEW and Measurement Studio. The Company's
software tools for motion are easily integrated with the Company's other product
lines, allowing motion to be combined with image acquisition, test, measurement,
data acquisition and automation.  The Company's  computer-based  motion products
allow users to leverage  standard  hardware  and  software  in  measurement  and
automation  applications  to create  robust,  flexible  solutions.  In 2001, the
Company  introduced new low-cost motion controllers for stepper and servo motors
and new power drives for servo motors.

     Industrial  Communications  Interfaces.  In  mid-1995,  the  Company  began
shipping its first interface boards for communicating with serial devices,  such
as dataloggers and PLCs targeted for IA applications,  and benchtop instruments,
such as oscilloscopes,  targeted for T&M applications.  Industrial  applications
need  the  same  high-quality,  easy-to-use  hardware  and  software  tools  for
communicating  with industrial  devices such as process  instrumentation,  PLCs,
single-loop  controllers,  and a  variety  of  I/O  and  DAQ  devices.  National
Instruments   offers  four  hardware  and  driver  software  product  lines  for
communication with industrial devices--Controller Area Network (CAN), DeviceNet,
Foundation   Fieldbus,   and  RS-485  and  RS-232.   The  Company's   industrial
communication  products  are  designed  to work with  standard  serial  software
drivers, and Windows versions of LabVIEW and Measurement Studio.

     Distributed  I/O  and  Embedded  Control  Hardware/Software.   The  Company
introduced its FieldPoint  product for distributed I/O applications in mid-1997.
FieldPoint  is an  intelligent,  distributed,  and modular I/O system that gives
industrial  system  developers  an  economical  solution  for  distributed  data
acquisition, monitoring and control applications. Suitable for direct connection
to industrial  signals,  FieldPoint includes a wide array of rugged and isolated
analog and digital I/O modules,  terminal  base  options,  and network  modules.
FieldPoint software provides seamless integration into the LabVIEW Real-Time and
LabVIEW  Datalogging  and  Supervisory  Control  Modules,  driver  libraries for
support under LabVIEW,  Measurement  Studio and Lookout,  and an OPC server that
provides  wide  compatibility  of  FieldPoint  hardware  with  other  industrial
automation  software  packages.  The FieldPoint 2000 family of real-time network
control modules,  which were introduced in 2001,  enable LabVIEW Real-Time users
to  download  their  LabVIEW  code  and  easily  create  networked   systems  of
intelligent, real-time nodes for embedded measurement and control.

before they enter the work force.


     Sales and Distribution

     The Company  distributes  its  software  and  hardware  products  primarily
through  a  direct  sales  organization.   The  Company  also  uses  independent
distributors,  OEMs,  VARs,  system  integrators  and  consultants to market its
products.  The Company has sales  offices in the United States and sales offices
and distributors in key  international  markets.  Sales outside of North America
accounted for approximately 49%, 47%, and 47% of the Company's revenues in 2001,
2000, and 1999, respectively.  The Company expects that a significant portion of
its total  revenues will continue to be derived from  international  sales.  See
Note 12 of Notes to Consolidated Financial Statements for details concerning the
geographic   breakdown  of  the  Company's  net  sales,   operating  income  and
identifiable assets.

     Through all of its sales channels,  the Company seeks to approach potential
customers with a highly  technical  sales force.  The Company  believes that the
majority of sales are made directly to those persons within an organization  who
actually use the Company's products to integrate their own systems.  The Company
identifies and targets major end-user accounts as those having a large number of
actual or potential  end users,  and  believes  that it achieves a high level of
repeat  customer  sales.  The Company  targets major  accounts with a variety of
targeted  sales  and  marketing   campaigns  such  as  seminars,   user  groups,
newsletters and direct mail.

     Throughout 2001, the Company continued to invest  aggressively to integrate

     Direct Sales

     The Company directly markets and sells its products in the Americas, Europe
and Asia. The Company has sales offices located throughout the United States and
in key international markets. Many of the Company's  international sales offices
employ application  engineering  technical support specialists as well as sales,
marketing and administrative personnel.

                                      -11-


     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 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 US dollars.  These  dynamics  have
adversely affected revenue growth in international  markets in recent years. See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations" and Note 11 of Notes to Consolidated Financial Statements.


     Distributors

     The  Company  utilizes  distributors  primarily  to market its  products in
geographic  areas  not  served  by  the  Company's  direct  sales  organization.
Generally,  the Company's  indirect sales customers do not maintain  significant
inventory levels.


     OEMs

     The Company utilizes OEMs such as traditional instrument  manufacturers and
automatic test equipment  (ATE) system  suppliers who offer  integrated  systems
and/or  services to their customer  bases.  The Company  approaches OEM accounts
with its standard  product lines and offers  quantity  discounts based on volume
commitments and technical  support  capabilities and  requirements.  The Company
also  promotes  its sales and  marketing  capabilities  to its OEMs by providing
specialized  product  training,  documentation,  packaging  and part  numbers to
simplify  ordering,  flexible  shipping  and warranty  repair  options and joint
promotion.


     VARs, System Integrators and Consultants

     The Company has relationships with third-party VARs, system integrators and
consultants who offer add-on  products and system  integration  services.  These
third-party  developers  expand the Company's market and sales  opportunities by
adding  value to the  Company's  standard  products,  making them  suitable  for
vertical  market   applications  such  as  manufacturing   automation  or  image
processing   and   analysis.   The  Company   maintains  a  formal   third-party
sales/marketing/training  program, called the Alliance Program, which it uses to
work with many of the VARs, system integrators and consultants.  Applicants must
be sponsored  for  membership by a Company sales  engineer,  pass  qualification
criteria  and pay a nominal  annual  membership  fee. In late 1998,  the Company
introduced an elite level of its Alliance  Program  called  Select  Integrators.
Select  Integrators  must  qualify  for the  program  based upon their  level of
business  with the  Company.  As of December 31, 2001,  the  Company's  Alliance
Program had approximately 554 members including several Select Integrators.  The
Company  publishes  on-line  directories  on its NI.com Web site of  third-party
Alliance Program member products and services for use by its sales force and its
end users to locate  additional  products  and/or  services  compatible with the
Company's products.  The Company makes available to qualified  third-parties the
opportunity to participate in joint marketing and sales programs,  such as trade
shows, customer sales events and the Company's  newsletters.  In addition to its
relationships  with third party VAR,  system  integrators and  consultants,  the
Company has a direct presence in the German systems  integration  market through
its German subsidiaries.


     Customer Support

     The  Company  believes  the  ability to provide  comprehensive  service and
support to its  customers is an important  factor in its  business.  The Company
permits customers to return products within 30 days from receipt for a refund of
the purchase price less a restocking  charge,  and generally provides a two-year
warranty  on GPIB  hardware  products,  a one-year  warranty  on other  hardware
products,  and a 90-day warranty on cables and software (medium only). Customers
may  also  purchase  a  one-year   extended   warranty  on  hardware   products.
Historically, warranty costs have not been material. Some of the key elements of
the Company's service and support strategy include:

                                      -12-


     Customer Technical Support

     The Company maintains a large staff of application  engineers,  all of whom
are  highly  qualified  technical  professionals.  These  application  engineers
provide customer support by telephone,  fax,  electronic mail and world-wide Web
forums, and electronic bulletin boards, and are trained in both  instrumentation
and computer  technology.  In 2001,  the Company  continued to invest heavily to
leverage the Web for customer  support.  Through the Company's  NI.com web site,
customers  have access to a growing range of support  options to solve their own
problems directly over the Web, including software  downloads,  upgrades and bug
fixes,  automated product  configuration  tools,  knowledge  databases of common
questions and answers, live Web chat capabilities,  live product demonstrations,
and discussion forums.


     Upgrades

     The Company  typically  offers  programs in which  existing  customers  can
upgrade to the latest Company products for an upgrade fee.  Application software
customers  have the option of purchasing a one-year  renewable  maintenance  and
support  program,  which  entitles  them to  unspecified  software  upgrades and
priority access to the Company's technical support hotline.


     Customer Education

     The Company offers a variety of fee-based training classes ranging in scope
from  basic and  introductory  courses  for new users to  advanced  courses  for
experienced users.


     Competition

     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").  The Company believes
Agilent is the  dominant  supplier of GPIB and  VXI-compatible  instruments  and
systems.  Agilent  is  also  a  leading  supplier  of  equipment  used  in  data
acquisition  and  control  applications.  Agilent  offers  its own  line of GPIB
instrument  controllers,  as well as hardware and software  add-on  products for
third-party  desktop  computers and workstations  that directly compete with the
Company's  products.  Agilent is  aggressively  advertising  and  marketing  its
products and system integration services.  Because of Agilent's dominance in the
instrumentation business, changes in its marketing strategy or product offerings
could have a material  adverse  affect on the  Company.  The Company  also faces
competition from a variety of other competitors.

     Certain  of  the  Company's   competitors  have   substantial   competitive
advantages  in terms of breadth of  technology,  sales,  marketing  and  support
capability and resources,  including the number of sales and technical personnel
and their  ability to cover a  geographic  area and/or  particular  account more
extensively  and with more complete  solutions  than the Company can offer,  and
more extensive  warranty support,  system  integration and service  capabilities
than those of the Company.  In addition,  large competitors can often enter into
strategic alliances with key customers or target accounts of the Company,  which
can  potentially  have a negative  impact on the  Company's  success  with those
accounts.

     The  Company  believes  its  ability to compete  successfully  depends on a
number of factors  both  within and  outside  its  control,  including:  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;  success in leveraging the Web;  strategic  relationships with other
suppliers;   timing  of  new  product   introductions  by  the  Company  or  its
competitors;   protection  of  the  Company's   products  by  effective  use  of
intellectual  property laws; general market and economic conditions;  and events
related to weather and government  actions throughout the world. There can be no
assurance that the Company will be able to compete successfully in the future.

     The Company is continually  designing new and improved products to maintain
its competitive  position.  Because of the rapidly changing computer  technology
for which many of the Company's products are designed, the Company believes that
its future success will depend in part on its ability to continue to improve its
products and technologies.  In the past, certain competitors have cloned some of
the  Company's  hardware  products  at much lower  prices,  and  promoted  these
hardware  products  as being  capable of running  the  Company's  software.  The
Company has  responded to this tactic in the past by releasing  new and improved
versions of its products that have improved  performance and functionality in an
effort to  surpass  the  competition.  Certain  competitors  have also  released
products  similar to the Company's  software  products that the Company believed
infringed the Company's  software patents.  The Company has successfully  abated
some infringement of its software patents through patent litigation activities.

                                      -13-


     Research and Development

     The Company  believes that its  long-term  growth and success  depends,  in
part,  on  delivering  high quality  software and hardware  products on a timely
basis.  The Company  intends to focus its  research and  development  efforts on
enhancing  existing  products  and  developing  new  products  that  incorporate
appropriate  features  and  functionality  to be  competitive  with  respect  to
technology and price/performance.

     The Company's  research and development staff strives to build quality into
products  at the design  stage in an effort to reduce  overall  development  and
manufacturing  costs. The Company's  research and development staff also designs
proprietary  ASICs, many of which are designed for use in several products.  The
goal of the ASIC  design  program  is to  further  differentiate  the  Company's
products from competing  products,  to improve  manufacturability  and to reduce
costs.  The  Company  seeks to reduce  the time to market  for new and  enhanced
products by sharing its internally  developed  hardware and software  components
across multiple products.

     In  the  past,  the  Company  has  experienced  significant  delays  in the
introduction  of new  products.  The Company's  strategy of developing  products
which  depended  upon third  parties'  commercially  available  technologies  is
substantially  dependent on the Company's ability to gain pre-release access to,
and to develop  expertise in,  current and future product  developments  of such
companies.  There can be no assurance  that the Company will continue to receive
such pre-release access from any of these companies,  or, even with such access,
that the Company  will be able to develop  products  on a timely  basis that are
compatible with future releases.

     The Company has implemented  certain  programs,  including  pre-release bug
analysis measures and enhanced project-tracking efforts, in order to improve the
product  development  process and to permit more  accurate  product  development
scheduling.  Nonetheless,  there can be no assurance that the Company's research
and development  efforts will not encounter delays or other  difficulties,  that
development efforts will result in commercially successful products, or that the
Company's  products will not be rendered obsolete by changing  technology or new
product announcements by other companies.

     As of  December  31,  2001,  the  Company  employed  720  people in product
research and development.  The Company's research and development  expenses were
$60.7  million,  $56.0  million,  and $45.5  million  for 2001,  2000,  and 1999
respectively.


     Intellectual Property

     The Company relies on a combination of patent, trade secret,  copyright and
trademark  law,  contracts and  technical  measures to establish and protect its
proprietary  rights in its products.  As of December 31, 2001,  the Company held
152 United  States  patents  (147  utility  patents and 5 design  patents) and 6
patents  in  foreign  countries  (3  patents  registered  in Europe  in  various
countries;  1 patent in  Canada,  and 2 patents  in  Japan),  and had 164 patent
applications pending in the United States and foreign countries. Thirty eight of
such United States patents are software  patents  related to LabVIEW,  and cover
fundamental aspects of the graphical  programming  approach used in LabVIEW. The
Company's  patents  expire from 2007 to 2020. No assurance can be given that the
Company's  pending patent  applications  will result in the issuance of patents.
The Company also owns certain  registered  trademarks  in the United  States and
abroad.

     Although the Company  relies to some extent on trade secret  protection for
much of its technology,  and regularly obtains  confidentiality  agreements with
key  customers  who wish to know more about the  Company's  product  development
philosophy  and/or  future  directions,  there can be no  assurance  that  third
parties will not either  independently  develop the same or similar  technology,
obtain unauthorized access to the Company's proprietary technology or misuse the
technology to which the Company has granted access.

     The laws of certain  foreign  countries treat the protection of proprietary
rights of the  Company  in its  products  differently  from  those in the United
States, and in many cases the protection afforded by such foreign laws is not as
strong as in the United States. The Company believes that its products and their
use do not infringe the  proprietary  rights of third  parties.  There can be no
assurance, however, that infringement claims will not successfully be made.

                                      -14-


     Manufacturing and Suppliers

     The Company  manufactures  a majority of its products at its  facilities in
Austin,  Texas. Product  manufacturing  operations at the Company can be divided
into four areas:  electronic  circuit card and module assembly;  cable assembly;
technical manuals and product support  documentation;  and software duplication.
The Company  manufactures  most of the  electronic  circuit card  assemblies and
modules  in-house,  although  subcontractors  are used  from  time to time.  The
Company manufactures some of its electronic cable assemblies in-house,  but many
assemblies are produced by  subcontractors.  The Company primarily  subcontracts
its  software  duplication  and  packaging   functions.   Reliance  on  contract
manufacturers  entails  risks of  quality  problems,  less  control  of  product
pricing, and potential  unavailability of or delays in delivery of products, any
of which  could  have a  material  adverse  effect on the  Company's  results of
operations.  There  can be no  assurance  that the  Company,  together  with its
third-party manufacturers,  will be able to produce sufficient quantities of the
Company's products in a timely manner.

     The Company has implemented a customer focused quality system that involves
all  organizations.  The Company's  products are designed and tested in a formal
development  process and are controlled in  manufacturing  and  distribution  to
assure  that our  customers'  demands  are met.  Additionally,  the  Company  is
committed to  continuous  improvement  of the Company's  products,  services and
processes to assure long term customer satisfaction.

     During  2001,  the  Company  completed  a new  manufacturing  operation  in
Hungary.  The new  Hungarian  operation is the  Company's  second  manufacturing
facility  and the  Company  estimates  that by 2003  will  source a  significant
portion of the Company's  global  sales.  Any delay in bringing this facility to
maximum  capacity  could  have a  material  adverse  effect  on the  results  of
operations.

     The  marketplace  dictates that many of the  Company's  products be shipped
very  quickly  after  an  order  is  received.  Since  purchased  component  and
manufacturing  lead  times  are  typically  much  longer  than the  short  order
fulfillment  time, the Company is required to keep adequate  amounts of finished
goods inventory and must use an accurate system for forecasting demand for those
products in its production planning  operations.  Fluctuations in demand for the
Company's  products  typically  result  from  month-to-month  variations  in the
quantity and mix of products and from normal, seasonal variations.  A variety of
circumstances,   including   inaccurate   forecasts  of  customer  demand,  poor
availability of purchased  components,  supplier  quality  problems,  production
equipment problems, transport disruptions or damage to products in manufacturing
operations,  could create a buildup of excess  finished goods on the one hand or
an  inability  to  timely  deliver  product  on  the  other.  See  "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

     Engineering refinements to the Company's new hardware and software products
are  fairly  common.   These  changes  can  result  in  the  disruption  of  the
manufacturing  operation and concurrent delays in delivery dates. Finished goods
inventory at the Company's international warehouses and branches typically has a
short shelf life due to engineering  changes and product  upgrades  initiated by
the Company's product development  operation,  and, if managed incorrectly,  can
result in significant  quantities of obsolete  inventory.  This relatively short
shelf life,  and the resulting  requirement  to properly  manage the quantity of
inventory to meet customer demand while minimizing inventory  obsolescence,  has
been and continues to be a challenge to the Company and its branch offices.  See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations."

     The  Company  obtains  most of its  electronic  components  from  suppliers
located  principally  in the  United  States  and Asia.  Some of the  components
purchased by the Company,  including ASICs, are sole-sourced.  Any disruption of
the Company's  supply of sole or limited source  components,  whether  resulting
from business demand, quality,  production or delivery problems, could adversely
affect the Company's  ability to manufacture  its products,  which could in turn
adversely  affect  the  Company's  business  and  results  of  operations.   See
"Managements  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations."


     Backlog

     The Company  typically ships products  shortly  following the receipt of an
order. Accordingly, the Company's backlog typically represents less than 10 days
sales. Backlog should not be viewed as an indicator of future sales.


     Employees

     As of December 31, 2001, the Company had 2,849 employees,  including 720 in
research and development, 1,312 in sales and marketing and customer support, 472
in manufacturing  and 345 in administration  and finance.  None of the Company's
employees is represented by a labor union and the Company has never  experienced
a work stoppage.  The Company  considers its employee  relations to be good. For
three consecutive  years, 1999, 2000, and 2001, the Company has been named among
the 100 Best Companies to Work for in America according to FORTUNE magazine.

                                      -15-


ITEM 2.   PROPERTIES

     The Company's principal  administrative,  sales, marketing,  manufacturing,
research  and  development  activities  are  conducted  at  three  Company-owned
buildings in Austin,  Texas. The Company owns  approximately 69 acres of land in
north Austin,  Texas,  on which are a 232,000 square foot office  facility and a
140,000 square foot  manufacturing  and office  facility.  The Company is in the
process  of  constructing  a new R&D  building,  a 380,000  square  foot  office
facility with estimated completion during the first quarter of 2002. The Company
also owns a 136,000  square  foot office  building in Austin,  Texas in which it
houses  certain of its sales  operations.  A portion of the 136,000  square foot
office  building is  currently  leased to Trilogy,  Inc.  The Company also has a
148,000  square foot  manufacturing  facility  in  Debrecen,  Hungary,  that was
completed  in the  fall of  2001.  The  Company's  German  subsidiary,  National
Instruments  Engineering GmbH & Co. KG owns a 25,500 square foot office building
in Aachen, Germany in which a majority of its activities are conducted. National
Instruments  Engineering also owns another 19,375 square foot office building, a
portion of which is partially  leased to BMS Modern Games. The remainder of this
office building is used by National Instruments Engineering.

     As of December  31,  2001,  the  Company  also leased a number of sales and
support offices in the United States and overseas. The Company believes existing
facilities are adequate to meet its current requirements.


ITEM 3.   LEGAL PROCEEDINGS

     During 2000, the Company was served by Cognex Corporation, asserting patent
infringement  of  two  Cognex   patents,   copyright   infringement,   trademark
infringement and unfair competition.  Cognex sought permanent injunctive relief,
actual monetary damages in an unspecified  amount and attorney's fees and costs.
The Company  filed a response to the lawsuit  denying all claims.  In the fourth
quarter of 2000, the Company  accrued $2.5 million of  anticipated  intellectual
property  defense  costs that were probable of being  incurred.  The Company and
Cognex  settled the  dispute and Cognex  dismissed  the case with  prejudice  on
August 13, 2001.

     During 2001, the Company filed a complaint in U.S. District Court,  Western
District of Texas (Midland  Division) for  declaratory  judgment  arising from a
controversy between the Company and General Patent  Corporation,  General Patent
Corporation   International,   and  Acticon  Technologies,   LLC  ("Defendants")
concerning the enforceability,  validity, and infringement of certain patents in
which Defendants claim an interest.  Defendants claim that the Company infringes
these patents.  The Company  challenges the validity and enforceability of these
patents and asserts that it does not infringe the claims of these  patents.  The
Company  seeks  a  declaratory  judgment  of  invalidity  and  non-infringement.
Defendants  seek damages in an  unspecified  amount,  injunction  of the sale of
certain  products  of the  Company and  attorney's  fees and costs.  The case is
currently  in  discovery  and trial is set for May 5, 2003.  Due to the inherent
uncertainties of litigation, there can be no assurance that this litigation will
not cause significant liability and a diversion of management's  attention which
may have a material adverse effect on results of operations.

     As a result of the  aforementioned  Cognex dismissal and the General Patent
Corporation  matter,  the Company has reduced its intellectual  property defense
cost accrual by approximately $1.2 million.


ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matter was  submitted  to a vote of security  holders  during the fourth
quarter of the fiscal year covered by this report.

                                      -16-


                                     PART II

ITEM 5.   MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
          MATTERS

     The Company's  Common Stock,  $0.01 par value,  began trading on the Nasdaq
National Market System under the symbol NATI effective March 13, 1995.  Prior to
that date,  there was no public  market for the Common  Stock.  The high and low
closing prices for the Common Stock, as reported by Nasdaq,  are as indicated in
the following table.

                                               High     Low
        2001
        First Quarter 2001...................  56.125   31.563
        Second Quarter 2001..................  38.14    26.688
        Third Quarter 2001...................  38.80    26.00
        Fourth Quarter 2001..................  39.70    25.37

                                               High     Low
        2000
        First Quarter 2000...................  50.188   34.938
        Second Quarter 2000..................  56.75    33.00
        Third Quarter 2000...................  48.875   40.813
        Fourth Quarter 2000..................  52.438   37.063

     At the close of business on February 15, 2002, there were approximately 678
holders of record of the Common Stock and approximately  10,500  shareholders of
beneficial interest.

     The Company believes  factors such as quarterly  fluctuations in results of
operations,  announcements  by the  Company  or its  competitors,  technological
innovations, new product introductions,  governmental regulations, litigation or
changes in  earnings  estimates  by analysts  may cause the market  price of the
Common Stock to fluctuate, perhaps substantially.  In addition, stock prices for
many technology  companies fluctuate widely for reasons that may be unrelated to
their  operating  results.  These broad  market and  industry  fluctuations  may
adversely affect the market price of the Company's Common Stock.

     To date,  the Company has not paid any cash  dividends on its Common Stock.
The Company  currently  anticipates  that it will retain any available  funds to
finance the growth and operation of its business and does not anticipate  paying
any cash dividends in the immediate future.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     The  discussion  in  this  document   contains  trend  analysis  and  other
forward-looking  statements  within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended.  Actual results could differ  materially from those projected in the
forward-looking  statements  throughout this document as a result of a number of
important  factors.  For a discussion of important factors that could affect the
Company's  results,  please refer to the risk factors set forth below in Factors
Affecting the Company's  Business,  in the financial line item discussions below
and elsewhere in this document.


Overview

     National  Instruments  Corporation  designs,  develops,   manufactures  and
markets  instrumentation  and  automation  software  and  hardware  for  general
commercial,  industrial and scientific applications. The Company offers hundreds
of products used to create virtual  instrumentation  systems for measurement and
automation.  The Company has  identified a large and diverse market for test and
measurement ("T&M") and industrial automation ("IA") applications. The Company's
products are used in a variety of applications  from research and development to
production  testing,  monitoring and industrial control. In test and measurement
applications,  the  Company's  products  can be  used  to  monitor  and  control
traditional instruments or to create computer-based instruments that can replace
traditional instruments.  In industrial automation  applications,  the Company's
products can be used in the same ways as in test and measurement and can also be
used  to   integrate   measurement   functionality   with   process   automation
capabilities. The Company sells to a large number of customers in a wide variety
of industries.  No single  customer  accounted for more than 3% of the Company's
sales in 2001, 2000 or 1999.

     The Company has been  profitable in every year since 1990.  However,  there
can be no assurance  that the  Company's net sales will grow or that the Company
will remain  profitable in future  periods.  As a result,  the Company  believes
historical  results of operations  should not be relied upon as  indications  of
future performance.

                                      -19-

     Net  Sales.  In 2001,  net sales for the  Company's  products  were  $385.3
million,  a 6%  decrease  from the level  achieved  in 2000,  which  followed an
increase  in net  sales of 24% in 2000  over the  level  achieved  in 1999.  The
Company believes the decrease in sales in 2001 is primarily  attributable to the
approximate 25% decline in the sales of certain hardware  products that are used
to control  traditional  instruments,  which  resulted from the worsening of the
industrial  economy  and  the  severe  deterioration  of  sales  of  traditional
instruments by other vendors used in test and measurement applications. In 2001,
the sales of hardware products that are used to control traditional  instruments
represented 22% of revenue compared to 27% in 2000 and 25% in 1999.

     North  American  revenue was $196.0  million in 2001, a decrease of 9% from
2000,  following a 23%  increase in 2000 over 1999.  The  Company  believes  the
decrease  in sales and in the revenue  growth  rate in North  America in 2001 is
primarily  attributable  to the  decrease  in  sales of the  Company's  hardware
products  that are used to control  traditional  instruments  as a result of the
downturn in the test and measurement  market. This downturn was most significant
in  sales  to  customers   in  the   telecommunications,   instrumentation   and
semiconductor capital equipment industries.

     European  revenue was $128.5  million in 2001,  a decrease of 6% from 2000,
following a 23%  increase in 2000 from 1999.  Asia  Pacific  revenue  grew 5% to
$60.9 million in 2001,  which  followed a 35% increase in 2000 over 1999 levels.
The Company believes the decrease in revenue in Europe,  and the decrease in the
revenue  growth rate in Asia  Pacific in 2001 is primarily  attributable  to the
decrease in sales of the  Company's  hardware  products that are used to control
traditional  instruments,  the result of the downturn in the industrial economy,
and the  strengthening  of the U.S.  Dollar.  See the discussion  below for more
information  concerning  the impact of foreign  currency  fluctuations  on sales
growth.

                                      -20-


     International sales (sales to customers outside of North America) accounted
for 49%, 47% and 47% of the Company's  consolidated net sales for 2001, 2000 and
1999, respectively.  The Company intends to continue to expand its international
operations by increasing its presence in existing markets, add a market presence
in some additional geographical markets and continue to use distributors to sell
its products in some countries.

     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 2001 and
2000, this weighted average value of the U.S. dollar increased by 6.0%,  causing
an  equivalent  decrease  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
during  2001  had  been the same as that in  2000,  on a  pro-forma  basis,  the
Company's  sales for 2001 would have decreased by 2%.  Pro-forma  European sales
for 2001 would have  increased  by 6% over 2000 sales.  Pro-forma  Asia  Pacific
sales for 2001 would  have  increased  by 8% over 2000  sales.  If the  weighted
average value of the U.S.  dollar during 2001 had been the same as that in 2000,
on a pro-forma basis, the Company's  consolidated  operating expenses would have
been $237.6  million,  representing  an increase of $2.2 million.  The preceding
pro-forma amounts and percentages are not presented in accordance with generally
accepted accounting principles but are presented for comparative purposes.

     Gross Profit. As a percentage of sales,  gross profit  represented 74%, 76%
and 77% in 2001,  2000 and 1999,  respectively.  The  relatively  high  software
content of the Company's  products is demonstrated in the gross margins achieved
by the Company.  In 2001,  approximately 60% of the lower margin is attributable
to  reduced  sales  volume,  with the  remaining  fraction  of the lower  margin
primarily due to unfavorable  foreign currency  exchange rates.  There can be no
assurance that the Company will maintain its historical margins.

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

     Sales and Marketing.  Sales and marketing expense in 2001 decreased 1% from
2000,  which  followed an increase of 22% in 2000 from 1999. The decrease in the
expense  in 2001  is  attributable  to  decreases  in  travel,  advertising  and
literature  costs and special event  activities.  Sales and marketing  personnel
increased  by 127  during  2001  from  1,185 at  December  31,  2000 to 1,312 at
December 31, 2001.  Sales and  marketing  expense as a percentage of revenue was
38% in 2001, up from 36% in 2000 and 37% in 1999.

     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  expense  in  2001
increased  9% compared to 2000  following  an increase of 23% in 2000 over 1999.
Excluding  the pre-tax  charge for the  write-off  of  in-process  research  and
development, on a pro-forma basis, research and development expense grew 29% and
28% during  2000 and 1999,  respectively.  (See Note 8 of Notes to  Consolidated
Financial  Statements  for a  description  of the Company's  acquisitions.)  The
increase in research and development  expenditures  in absolute  amounts in each
period  was  primarily  due to  increases  in  personnel  costs  from  hiring of
additional product  development  engineers.  Research and development  personnel
increased from 672 at December 31, 2000 to 720 at December 31, 2001. The Company
plans to continue making a significant investment in research and development in
order to remain competitive.

     The Company  capitalizes  software  development  costs in  accordance  with
Statement of Financial Accounting Standards ("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 $3.1 million,  $2.6
million and $2.3 million  during  2001,  2000 and 1999,  respectively.  Software
development costs capitalized during such years were $3.9 million,  $5.0 million
and $2.8 million,  respectively.  The significant items capitalized in 2001 were
primarily the result of LabVIEW 6.1,  Measurement  Studio 6.0 and TestStand 2.0.
The increased levels of  capitalization  for 2000 were primarily a result of the
development  of  LabVIEW  6i,  NI-DAQ  6.9 and MAX 2.1.  (See Note 5 of Notes to
Consolidated Financial Statements for a description of intangibles.)

                                      -21-


     General and  Administrative.  General and  administrative  expenses in 2001
decreased 9% from 2000,  which  followed an increase of 32% in 2000 from 1999. A
significant  amount of the  decrease  was due to reduced  intellectual  property
defense  costs,  the result of the net recovery of $1.2 million of  intellectual
property   defense  costs  accrued  in  the  prior  year,   and  to  operational
efficiencies  resulting from continued  systems  improvement.  Implementation of
information systems to support the Hungarian manufacturing  facility,  upgrading
its worldwide  business  applications suite to Oracle's latest web-based release
11i and  continued  investment in the Company's web presence were the main areas
of focus for investment in the information  systems department in 2001. The 2001
decrease followed a 32% increase in 2000 which was primarily driven by continued
development of web and e-commerce  offerings and a $2.5 million charge  recorded
in the fourth quarter of 2000 for defending our intellectual  property.  General
and administrative  expenses as a percentage of revenue decreased to 7.5% during
2001 from 7.8% in 2000.  The decrease in 2001 was  primarily due to the recovery
of $1.2  million in 2001 of the $2.5  million  accrual  for future  intellectual
property  defense  costs  recorded  in the fourth  quarter of 2000.  The Company
expects that general and administrative  costs will increase in absolute amounts
and will fluctuate as a percentage of revenue as the Company continues to invest
in maintaining its existing systems,  developing the  infrastructure for the new
Hungarian   manufacturing  facility,  and  developing  web  based  commerce  and
management information systems.

     Interest  Income and  Expense.  Interest  income  decreased 9% in 2001 from
2000,  which  followed  an increase  of 34% in 2000 from 1999.  The  decrease in
interest  income in 2001 was  primarily  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 cash provided by operating  activities in 2001 totaled $57.2
million. Interest expense decreased 95% in 2001, the result of full repayment of
debt outstanding in 2000.

     Net  Foreign  Exchange  Gain/Loss.  The  Company  experienced  net  foreign
exchange  losses of $1.4 million in 2001,  compared to losses of $1.5 million in
2000 and gains of $130,000 in 1999.  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 and 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.  (See Note 12 of Notes to
Consolidated Financial Statements for a description of the Company's forward and
purchased option contracts and hedged positions.) The Company's hedging strategy
reduced the foreign  exchange  loss for  December  31, 2001 by $6.5  million and
reduced the net foreign exchange loss for December 31, 2000 by $10.2 million.

     Effective  January  1, 1999,  the  Company  elected to adopt SFAS No.  133,
"Accounting for Derivative Instruments and Hedging Activities." (See Note 10 and
Note 11 of Notes to Consolidated Financial Statements.)

     Provision  for Income Taxes.  The  provision  for income taxes  reflects an
effective  tax rate of 32% in 2001,  2000 and 1999.  The  effective  tax rate is
lower  than the  Federal  Statutory  rate  primarily  as a result of  tax-exempt
interest and the benefit of the Company's Foreign Sales Corporation. (See Note 6
of Notes to Consolidated Financial Statements.)


Liquidity and Capital Resources

     The Company is currently financing its operations and capital  expenditures
through cash flow from operations. At December 31, 2001, the Company had working
capital of  approximately  $209.8 million compared to $220.2 million at December
31, 2000.

     Accounts  receivable  decreased to $53.6  million at December 31, 2001 from
$74.7  million at  December  31,  2000,  as a result of lower  sales  levels and
improved collections. Receivable days outstanding at December 31, 2001 decreased
to 51 days from 60 days at December 31, 2000.  Consolidated  inventory  balances
have  decreased  to $32.6  million at December  31,  2001 from $33.3  million at
December 31, 2000. Inventory turns of 3.1 per year for 2001 represent a decrease
from turns of 3.3 per year for 2000 and reflect  the  decrease in sales from the
prior year.

     Cash used for investing  activities in 2001 includes  $65.3 million for the
purchase of property and equipment and  capitalization  of software  development
costs of $3.9 million.

     In October of 2000, the Company began  construction  of an office  building
("Mopac C") located on the North Austin campus. It is currently anticipated that
a  significant  portion  of the  construction  costs  will  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 range from $58
million to $62  million.  In  October of 2000,  the  Company  entered  into firm
commitments of approximately  $60 million for the new building.  The Company has
incurred  approximately  $44.4 million in construction  costs as of December 31,
2001, with the remainder  becoming payable in 2002. 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 has
signed  an  agreement  to lease  the  Millenium  building  to a third  party and
currently  estimates  that the net rental  income  from this  lease will  offset
approximately 30% of the projected operating costs from the Mopac C building.

     During 2001, the Company completed  construction of a second  manufacturing
facility  located  in  Hungary.  This  European  manufacturing  facility  became
operational in the forth quarter of 2001, and the Company estimates that by 2003
the facility  will source a  significant  portion of the  Company's  sales.  The
location of the facility has a cost base and tax rate  significantly  lower than
in the U.S.,  which should have the effect of reducing the cost of manufacturing
and lowering the consolidated tax rate. However,  there can be no assurance that
the actual  manufacturing  costs and tax rates will be lower. The total cost for
the new facility, including furniture, fixtures and equipment, was approximately
$18.4 million.

     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. The Company  estimates that its budgeted capital  expenditures
over the next fiscal year will be approximately $36 million.  As of December 31,
2001, the Company had no debt outstanding to financial institutions.

     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 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 2001 and 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)"
and Note 11 of Notes to Consolidated Financial Statements.)

     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.

                                      -23-


     The Company has no debt or off-balance sheet debt. As of December 31, 2001,
the Company has non-cancelable operating lease obligations of approximately $5.4
million and contractual  purchase  commitments with various suppliers of general
components  and  customized  inventory  and  components  of  approximately  $6.0
million.  As of December 31, 2001,  the Company has  outstanding  guarantees for
payment of  foreign  operating  leases,  customs  and  foreign  grants  totaling
approximately  $3.2  million.  (See Note 13 of Notes to  Consolidated  Financial
Statements.)  At December 31, 2001,  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 exchange rates on its results of operations and financial  position.
Based on the foreign exchange  instruments  outstanding at December 31, 2001, 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  $8.9  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.  (See  Note 10 of Notes to  Consolidated
Financial Statements for a description of the Company's financial instruments at
December 31, 2001 and 2000.)

     Short-term  Investments.  The fair value of the  Company's  investments  in
marketable  securities  at December 31, 2001 was $101.4  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
December  31,  2001,  a 100 basis point  increase or decrease in interest  rates
would result in a decrease or increase of approximately $500,000,  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 Pronouncements

     In July 2001, the Financial  Accounting  Standards  Board, or FASB,  issued
SFAS  No.  141,   "Business   Combinations."   SFAS  No.  141   eliminates   the
pooling-of-interests  method of accounting for business  combinations except for
qualifying business  combinations that were initiated prior to July 1, 2001. The
purchase  method  of  accounting  is  required  to be used for all the  business
combinations  initiated  after  June 30,  2001.  SFAS No. 141 also  defines  the
criteria for identifying  intangible assets for recognition apart from goodwill.
The Company  adopted SFAS No. 141 effective  July 1, 2001.  The adoption of this
accounting standard had no impact on the Company's current results of operations
or financial position.

                                      -24-


     In July 2001, the FASB issued SFAS No. 142,  "Goodwill and Other Intangible
Assets."  SFAS No.  142,  discontinues  amortization  of acquired  goodwill  and
instead requires annual impairment testing.  Separable intangible assets will be
amortized  over  their  useful  economic  lives and  tested  for  impairment  in
accordance  with SFAS No. 121,  "Accounting  for the  Impairment  of  Long-Lived
Assets to be Disposed of." Intangible  assets with an indefinite useful economic
life  will not be  amortized  until the life of the  asset is  determined  to be
finite.  For goodwill and  indefinite-lived  intangible assets acquired prior to
July 1, 2001, amortization will continue until adoption of SFAS No. 142 at which
time  amortization  will  cease  and a  transitional  impairment  test  will  be
performed.  Any impairment charges resulting from the initial application of the
new rules will be  classified  as a  cumulative  effect of change in  accounting
principle.  The Company  adopted SFAS No. 142  effective  January 1, 2002. As of
December 31, 2001,  the Company had net goodwill of  approximately  $4.9 million
and related amortization expense of goodwill of $751,000,  $716,000 and $180,000
for the years ended December 31, 2001, 2000 and 1999, respectively.  Adoption of
SFAS No. 142 will not have a material impact on the Company's financial position
or future results of operations.

     Also in July 2001,  the FASB  issued SFAS No.  143,  "Accounting  for Asset
Retirement  Obligations."  SFAS  No.  143  addresses  financial  accounting  and
reporting for obligations  associated with the retirement of tangible long-lived
assets and the associated asset retirement costs. The statement is effective for
financial  statements  for  fiscal  years  beginning  after June 15,  2002.  The
adoption  of SFAS No.  143 is not  expected  to have an impact on the  Company's
financial position or results of operations.

     In  October  2001,  the FASB  issued  SFAS  No.  144,  "Accounting  for the
Impairment or Disposal of Long-Lived  Assets." SFAS No. 144 supersedes  previous
guidance for financial  accounting  and reporting for the impairment or disposal
of  long-lived  assets and for  segments of a business  to be  disposed  of. The
Company adopted SFAS No. 144 on January 1, 2002. The adoption of SFAS No. 144 is
not expected to have an impact on the Company's financial position or results of
operations.


Critical Accounting Policies

     The Company's critical accounting policies are as follows:

     o    Revenue recognition

          Revenue from the sale and  licensing of products is  recognized on the
          date the product is shipped to the  customer.  Revenue  related to the
          sale  of  maintenance   contracts  is  deferred  and  amortized  on  a
          straight-line basis over the service period.

     o    Estimating  allowances,  specifically sales returns, the allowance for
          doubtful accounts and allowance for excess and obsolete inventory

          The preparation of financial  statements  requires the Company to make
          estimates and  assumptions  that affect the reported  amount of assets
          and disclosure of contingent assets and liabilities at the date of the
          financial statements and the reported amounts of revenues and expenses
          during  the  reported  period.  Specifically,  the  Company  must make
          estimates  of  potential  future  product  returns  related to current
          period  product  revenue.   Management  analyzes  historical  returns,
          current economic trends, and changes in customer demand and acceptance
          of our products when  evaluating the adequacy of the sales returns and
          other allowances.  Significant management judgments and estimates must
          be made and used in connection with establishing the sales returns and
          other  allowances in any  accounting  period.  The allowance for sales
          returns was $1.5 million at December 31,  2001.  Material  differences
          may result in the amount and timing of the  Company's  revenue for any
          period if management  made different  judgments or utilized  different
          estimates.  Similarly,  our  management  must  make  estimates  of the
          uncollectability of our accounts receivables.  Management specifically
          analyzes  accounts  receivable  and  analyzes  historical  bad  debts,
          customer concentrations, customer credit-worthiness,  current economic
          trends and changes in our customer  payment terms when  evaluating the
          adequacy of the  allowance  for doubtful  accounts.  The allowance for
          doubtful  accounts was $4.9 million at December 31, 2001.  The Company
          writes down its inventory for estimated  obsolescence  or unmarketable
          inventory  equal to the  difference  between the cost of inventory and
          estimated  market  value based on  assumptions  on future  demands and
          market conditions. The allowance for excess and obsolete inventory was
          $2.9 million at December 31, 2001.  If actual  market  conditions  are
          less  favorable  than  those   projected  by  management,   additional
          inventory write downs may be required.

                                      -25-


     o    Accounting for costs of computer software

          The  Company   capitalizes   costs  related  to  the  development  and
          acquisition  of certain  software  products.  Capitalization  of costs
          begins when  technological  feasibility has been  established and ends
          when the  product is  available  for  general  release  to  customers.
          Amortization  is computed  on an  individual  product  basis for those
          products  available  for market and has been  recognized  based on the
          product's  estimated  economic life,  generally  three years.  At each
          balance sheet date, the  unamortized  costs are reviewed by management
          and reduced to net realized value when  necessary.  As of December 31,
          2001,  unamortized  capitalized  software  development  costs was $7.5
          million.

     o    Valuation of long-lived and intangible assets

          The Company  assesses the  impairement  of  identifiable  intangibles,
          long-lived  assets and related goodwill  whenever events or changes in
          circumstances indicate that the carrying value may not be recoverable.
          Factors considered  important which could trigger an impairment review
          include the following:

          o    Significant  underperformance  relative to expected historical or
               projected future operating results;

          o    Significant  changes  in the manner of the  Company's  use of the
               acquired assets or the strategy for the overall business;

          o    Significant negative industry or economic trends;

          o    The Company's market capitalization relative to net book value.

          When  it  is  determined  that  the  carrying  value  of  intangibles,
          long-lived  assets and related  goodwill may not be recoverable  based
          upon  the  existence  of  one  or  more  of the  above  indicators  of
          impairment,  the  measurement  of any impairment is determined and the
          carrying value is reduced as appropriate. As of December 31, 2001, the
          Company had net goodwill of approximately $4.9 million.


Factors Affecting the Company's Business

     U.S./Global  Economic  Slowdown.  As occurred in 2001 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 2002.  The
Company's spending for 2002 could exceed this budget due to a number of factors;
including:   additional  marketing  costs  for  any  unplanned  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, most recently in
the quarter ended March 31, 2001, and as may be expected to occur in the future,
supply  shortages of components  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.
The Company expects the strength of the U.S. dollar to have a negative effect on
gross and net profit margins in future quarters.

                                      -26-


     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.

     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 impact on the Company's 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.   During  2001,  the  Company   devoted
significant  resources to  implementing  information  systems to support its new
manufacturing facility in Europe. The Company also devoted significant resources
to  the  evaluation  and   development  of  an  advanced   planning  system  for
manufacturing and to continued development of web offerings. On January 7, 2002,
the Company implemented I2 factory planner, an advanced  manufacturing  planning
system  for  enhanced  predictability  of  material  flow  in its  manufacturing
operation.  The  Company  is  currently  monitoring  the  effects  of this newly
implemented  system  on  its  inventory  levels,  manufacturing  efficiency  and
backlog.  If the effect on  inventory  levels and material  flow is adverse,  it
could result in the Company having to attempt to revert back to its  predecessor
system of material flow planning. If the effect of the new I2 planning system is
adverse  and if the  Company is unable to  re-implement  its  previous  planning
system  in a timely  manner,  it  could  impact  the  Company's  future  product
shipments and revenues which accordingly could have a material adverse effect on
the  results of  operations.  In 2002,  the  Company  will also be  focusing  on
upgrading its Japanese office's business  applications  suite to Oracle's latest
web-based release 11i, and will continue to devote significant  resources to the
development of the web.  Failure to  successfully  implement  these  initiatives
could have a material adverse effect on the results of operations.

                                      -27-


     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  due to the
shipments, which would not occur until following periods. 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 ensure
compliance 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 2001 and 2000, the weighted
average  value of the U.S.  dollar  increased  by 6.0%,  causing  an  equivalent
decrease in the U.S.  dollar value of the Company's  foreign  currency sales and
expenses. If the weighted average value during 2001 had been the same as that in
2000, the Company's sales for 2001 would have decreased by 2.0%. If the weighted
average  value  during  2001 had been  the same as that in 2000,  the  Company's
consolidated operating expenses would have been $237.6 million,  representing an
increase of $2.2 million. If the U.S. dollar strengthens again in the future, it
could have a materially adverse effect on the operating results of the Company.

     As of December 31, 2001,  the Company has $9.4 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 24 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.

     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 has occurred in the past,  most  recently in the
quarter ended  December 31, 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 operating results.

                                      -28-


     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  integration  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 revenues
and results of operations.

     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.  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.  During  2001,  the Company  filed for
declaratory  judgement concerning the enforceability,  validity and infringement
of  certain  patents  in  which  General  Patent  Corporation,   General  Patent
Corporation International and Acticon Technologies,  LLC ("Defendants") claim an
interest. Defendants claim the Company infringes these patents and seeks damages
in an  unspecified  amount,  injunction  of the sale of certain  products of the
Company and  attorney's  fees and costs.  The Company  asserts  that it does not
infringe  these  patents and seeks a  declaratory  judgement of  invalidity  and
non-infringement. The case is currently in discovery and trial is set for May 5,
2003.  Matters  currently  in  litigation  and any other  intellectual  property
litigation  initiated in the future may cause  significant  litigation  expense,
liability and a diversion of  management's  attention  which may have a material
adverse  effect on results of  operations.  In the fourth  quarter of 2001,  the
Company accrued  $900,000,  the estimated legal fees for defending  intellectual
property litigation.

     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 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 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 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 13.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     During  2001,  the  Company  acquired a 10%  minority  interest  in another
company for $2.5 million.  Because of the Company's ownership percentage and its
lack of  control  and  inability  to exert  influence  over  this  entity,  this
investment is accounted for under the cost method.  Sales to this company during
2001 were $96,000.  The Company has no other  minority  investments in any other
entities.

     In  addition,  the  information  required by this item is  incorporated  by
reference  to  the  Company's  Proxy   Statement  under  the  heading   "Certain
Relationships and Related Transactions."

                        Report of Independent Accountants

To the Board of Directors and Stockholders
of National Instruments Corporation

     In  our  opinion,  the  consolidated  financial  statements  listed  in the
accompanying  index  present  fairly,  in all material  respects,  the financial
position of National  Instruments  Corporation and its  subsidiaries at December
31, 2001 and 2000, and the results of their  operations and their cash flows for
each of the three years in the period ended December 31, 2001 in conformity with
accounting  principles  generally  accepted in the United States of America.  In
addition,  in our  opinion,  the  financial  statement  schedule  listed  in the
accompanying  index presents fairly, in all material  respects,  the information
set  forth  therein  when  read in  conjunction  with the  related  consolidated
financial  statements.   These  financial  statements  and  financial  statement
schedule are the responsibility of the Company's management;  our responsibility
is to express an opinion on these financial  statements and financial  statement
schedule  based on our audits.  We conducted  our audits of these  statements in
accordance with auditing  standards  generally  accepted in the United States of
America,  which require that we plan and perform the audit to obtain  reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the  amounts  and  disclosures  in  the  financial  statements,   assessing  the
accounting  principles  used and significant  estimates made by management,  and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

used in a variety of  applications  from research and  development to production
testing and industrial  control.  The following  industries and applications are
served  worldwide  by the Company:  advanced  research,  automotive,  commercial
aerospace,   computers  and  electronics,   continuous  process   manufacturing,
education,  government/defense,  medical research/pharmaceutical,  power/energy,
semiconductors,  automated test equipment,  telecommunications  and others.  The
financial statements have been prepared in accordance with accounting principles
generally accepted in the United States of America.


     Principles of consolidation

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

     Certain prior year amounts have been  reclassified to conform with the 2001
presentation.


     Use of estimates

     Judgments and estimates by management  are required in the  preparation  of
financial  statements to conform with generally accepted accounting  principles.
The estimates and underlying  assumptions  affect the reported amounts of assets
and  liabilities,  the disclosure of contingencies at the balance sheet date and
the reported  revenues and expenses for the period.  Actual results could differ
from those estimates.


     Cash and cash equivalents

     Cash and cash equivalents  include cash and highly liquid  investments with
maturities of three months or less at the date of acquisition.


     Short-term investments

     Short-term investments consist of corporate, state and municipal securities
with readily  determinable fair market values and original  maturities in excess
of three months. The Company's  investments are classified as available-for-sale
and  accordingly are reported at fair value,  with  unrealized  gains and losses
reported as other  comprehensive  income.  Unrealized losses are charged against
income when a decline in fair value is  determined  to be other than  temporary.
The specific  identification  method is used to determine the cost of securities
sold.


     Inventories

     Inventories  are stated at the lower of cost or market.  Cost is determined
using standard costs,  which  approximate the first-in  first-out (FIFO) method.
Cost  includes  the  acquisition  cost  of  purchased   components,   parts  and
subassemblies,  in-bound freight costs, labor and overhead. Market, with respect
to raw materials,  is replacement cost and, with respect to work-in-process  and
finished goods, is net realizable value.

                        NATIONAL INSTRUMENTS CORPORATION

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


     Inventory  is shown net of allowance  for excess and obsolete  inventory of
$2.9 million and $2.5 million at December 31, 2001 and 2000, respectively.


     Property and equipment

     Property and equipment are recorded at cost. Depreciation is computed using
the  straight-line  method over the estimated useful lives of the assets,  which
range  from  twenty to forty  years for  buildings  and three to five  years for
equipment.  Leasehold  improvements are depreciated over the shorter of the life
of the lease or the asset.


     Intangible assets

     The  Company  has   capitalized   costs  related  to  the  development  and
acquisition  of certain  software  products.  In  accordance  with  Statement of
Financial  Accounting  Standards  ("SFAS") No. 86,  "Accounting for the Costs of
Computer Software to Be Sold, Leased or Otherwise  Marketed,"  capitalization of
costs begins when  technological  feasibility has been established and ends when
the product is  available  for general  release to  customers.  Amortization  is
computed on an individual  product basis for those products available for market
and  has  been  recognized  based  on the  product's  estimated  economic  life,
generally  three years.  At each balance sheet date, the  unamortized  costs are
reviewed by management and reduced to net realizable value when necessary.

     The  excess  purchase  price  over the fair  value of  assets  acquired  is
recorded as goodwill and is amortized  using the  straight-line  method over ten
years.  Intangible assets are periodically  assessed for impairment of value and
any loss is recognized upon impairment.


     Concentrations of credit risk

     Financial   instruments   that   potentially   subject   the   Company   to
concentrations  of credit risk consist  principally of foreign  currency forward
and option  contracts,  cash and cash  equivalents,  short-term  investments and
trade accounts receivable. In management's opinion, no significant concentration
of credit risk exists for the Company.

     The Company's  counterparties  in its foreign  currency  forward and option
contracts  are major  financial  institutions.  The Company does not  anticipate
nonperformance  by these  counterparties.  The Company  maintains  cash and cash
equivalents  with  various  financial  institutions  located  in many  countries
worldwide.  The  Company's  short-term  investments  are  diversified  among and
limited to high-quality  securities with high credit ratings.  Concentration  of
credit  risk with  respect to trade  accounts  receivable  is limited due to the
large  number of  customers  and their  dispersion  across  many  countries  and
industries.  The amount of sales to any individual customer did not exceed 3% of
revenue for the periods presented.  The amount of trade accounts receivable from
any individual customer at December 31, 2001 was not in excess of $1.3 million.


     Revenue recognition

     Sales  revenue  is  recognized  on the date the  product  is shipped to the
customer.  Provision  is made  for  estimated  sales  returns  based  on  actual
historical  experience.  Revenue related to the sale of maintenance contracts is
deferred  and  amortized  on a  straight-line  basis  over the  service  period.
Deferred  revenue at December 31, 2001 and 2000 is $2.6 million and $3.0 million
respectively.

     Accounts  receivable  are net of allowances  for doubtful  accounts of $4.9
million and $4.5 million at December 31, 2001 and 2000, respectively.


     Warranty expense

     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.


     Legal defense costs

     The Company  accrues for legal defense costs on an  undiscounted  basis, in
accordance with SFAS No. 5, "Accounting for Loss Contingencies," when such costs
are  considered  probable of being incurred and are  reasonably  estimable.  The
Company  periodically  evaluates  available   information,   both  internal  and
external, relative to such contingencies and adjusts this accrual as necessary.

                                      -F8-


     Advertising expense

     The Company  expenses its costs of  advertising  as  incurred.  Advertising
expense for the years ended  December 31, 2001,  2000 and 1999 is $30.4 million,
$35.4 million and $34.1 million, respectively.


     Foreign currency translation

     The functional currency for the Company's  international  operations is the
applicable  local currency.  The assets and liabilities of these  operations are
translated  at the rate of exchange in effect on the balance  sheet date;  sales
and expenses are translated at average rates. The resultant gains or losses from
translation are included in a separate component of other comprehensive  income.
Gains and  losses  resulting  from  remeasuring  monetary  asset  and  liability
accounts that are denominated in a currency other than a subsidiary's functional
currency are included in determining net income.


     Foreign currency hedging instruments

     The Company adopted SFAS No. 133,  "Accounting  for Derivative  Instruments
and Hedging  Activities,"  on January 1, 1999. In accordance with the transition
provisions of SFAS No. 133, the Company recorded a net-of-tax  cumulative-effect
adjustment  of  $552,000  in  earnings  to  recognize  the  fair  value  of  its
derivatives designated as cash-flow hedging instruments at the date of adoption.

     All of the Company's  derivative  instruments are recognized on the balance
sheet at their fair value.  The Company  currently uses foreign currency forward
and  purchased  option  contracts  to hedge its  exposure  to  material  foreign
currency denominated receivables and forecasted foreign currency cash flows.

     On the date the derivative contract is entered into, the Company designates
its  derivative  as  either  a hedge  of the  fair  value  of  foreign  currency
denominated receivables ("fair-value" hedge) or as a hedge of the variability of
foreign  currency cash flows to be received ("cash flow" hedge).  Changes in the
fair market value of a  fair-value  hedge are  recorded,  along with the loss or
gain  on the  re-measurement  of  foreign-currency-denominated  receivables,  in
current  earnings.  Changes  in the fair  value of  derivatives  that are highly
effective  as--and that are  designated  and qualify  as--cash flow hedges under
SFAS No. 133 are  recorded  in other  comprehensive  income.  These  amounts are
subsequently  reclassified  into  earnings in the period  during which the hedge
transaction  is realized.  As of December 31, 2001,  the Company has not entered
into a derivative contract for speculative purposes.

     The  Company   formally   documents  all   relationships   between  hedging
instruments  and hedged  items,  as well as its  risk-management  objective  and
strategy for  undertaking  various  hedge  transactions.  This process  includes
linking all derivatives that are designated as fair-value or cash flow hedges to
specific  assets  and  liabilities  on the  balance  sheet or to  specific  firm
commitments or forecasted transactions. The Company also formally assesses, both
at the hedge's  inception and on an ongoing basis,  whether the derivatives that
are used to hedge  forecasted  transactions  are highly  effective in offsetting
changes in cash flows of hedged items.

     The  Company  prospectively  discontinues  hedge  accounting  if  (1) it is
determined  that the  derivative  is no longer  highly  effective in  offsetting
changes  in the fair  value  or cash  flows of a  hedged  item  (including  firm
commitments or forecasted transactions);  (2) the derivative expires or is sold,
terminated  or  exercised;  (3)  the  derivative  is  de-designated  as a  hedge
instrument, because it is unlikely that a forecasted transaction will occur; (4)
the hedged firm commitment no longer meets the definition of a firm  commitment;
or (5)  management  determines  that  designation  of the  derivative as a hedge
instrument is no longer appropriate.

     When  hedge  accounting  is  discontinued  because  it is  probable  that a
forecasted  transaction  will not occur,  the  derivative  will  continue  to be
carried on the balance  sheet at its fair value,  and gains and losses that were
accumulated  in other  comprehensive  income will be recognized  immediately  in
earnings.  In all other situations  where hedge accounting is discontinued,  the
derivative will be carried as its fair value on the balance sheet,  with changes
in its fair value recognized in current-period earnings.


     Income taxes

     The Company  accounts for income taxes under the asset and liability method
as set forth in SFAS No. 109,  "Accounting  for Income Taxes." The provision for
income taxes is based on pretax financial accounting income. Deferred tax assets
and  liabilities  are recognized for the expected tax  consequences of temporary
differences  between the tax bases of assets and  liabilities and their reported
amounts.  Valuation allowances are established when necessary to reduce deferred
tax assets to amounts which are more likely than not to be realized.

                                      -F9-


     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 the basic EPS and
diluted EPS for the years ended December 31, 2001,  2000 and 1999,  respectively
are as follows (in thousands):

                                                      Years Ended December 31,

                                                    ========  ========  ========

     Stock options to acquire 1,394,000, 990,000 and 58,000 shares for the years
ended  December 31, 2001,  2000 and 1999,  respectively  were  excluded from the
computations of diluted earnings per share because the effect of including stock
options would have been anti-dilutive.


     Stock-based compensation plans

     The Company has adopted  the  disclosure-only  provisions  of SFAS No. 123,
"Accounting  for  Stock-Based  Compensation."  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.


     Comprehensive income

     The Company has adopted  SFAS No. 130,  "Reporting  Comprehensive  Income,"
which   established   standards   for  reporting  in  addition  to  net  income,
comprehensive  income  and its  components  including,  as  applicable,  foreign
currency items,  minimum pension liability  adjustments and unrealized gains and
losses on certain investments in debt and equity securities. Total comprehensive
income  for  2001,  2000 and 1999 was $36.4  million,  $56.1  million  and $42.7
million, respectively.


     Recently Issued Accounting Pronouncements

     In 2000, the Company  adopted Staff  Accounting  Bulletin  ("SAB") No. 101,
"Revenue  Recognition  in  Financial  Statements,"  which  provides  guidance in
applying generally accepted accounting principles to certain revenue recognition
issues.  The adoption of SAB 101 did not have a material impact on the Company's
financial position or overall trends in results of operations.

     In July 2001, the Financial  Accounting  Standards  Board, or FASB,  issued
SFAS  No.  141,   "Business   Combinations."   SFAS  No.  141   eliminates   the
pooling-of-interests  method of accounting for business  combinations except for
qualifying business  combinations that were initiated prior to July 1, 2001. The
purchase  method  of  accounting  is  required  to be used for all the  business
combinations  initiated  after  June 30,  2001.  SFAS No. 141 also  defines  the
criteria for identifying  intangible assets for recognition apart from goodwill.
The Company  adopted SFAS No. 141 effective  July 1, 2001.  The adoption of this
accounting standard had no impact on the Company's current results of operations
or financial position.

                                     -F10-



     Also in July  2001,  the FASB  issued  SFAS No.  142,  "Goodwill  and Other
Intangible Assets." SFAS No. 142, discontinues amortization of acquired goodwill
and instead requires annual impairment testing. Separable intangible assets will
be  amortized  over their useful  economic  lives and tested for  impairment  in
accordance  with SFAS No. 121,  "Accounting  for the  Impairment  of  Long-Lived
Assets to be Disposed of." Intangible  assets with an indefinite useful economic
life  will not be  amortized  until the life of the  asset is  determined  to be
finite.  For goodwill and  indefinite-lived  intangible assets acquired prior to
July 1, 2001, amortization will continue until adoption of SFAS No. 142 at which
time  amortization  will  cease  and a  transitional  impairment  test  will  be
performed.  Any impairment charges resulting from the initial application of the
new rules will be  classified  as a  cumulative  effect of change in  accounting
principle.  The Company  adopted SFAS No. 142  effective  January 1, 2002. As of
December 31, 2001,  the Company had goodwill of  approximately  $4.9 million and
amortization of goodwill of $751,000,  $716,000 and $180,000 for the years ended
December 31, 2001,  2000 and 1999,  respectively.  Adoption of SFAS No. 142 will
not have a material impact on the Company's financial position or future results
of operations.

     In July  2001,  the  FASB  issued  SFAS  No.  143,  "Accounting  for  Asset
Retirement  Obligations."  SFAS  No.  143  addresses  financial  accounting  and
reporting for obligations  associated with the retirement of tangible long-lived
assets and the associated asset retirement costs. The statement is effective for
financial  statements  for  fiscal  years  beginning  after June 15,  2002.  The
adoption  of SFAS No.  143 is not  expected  to have an impact on the  Company's
financial position or results of operations.

     In  October  2001,  the FASB  issued  SFAS  No.  144,  "Accounting  for the
Impairment or Disposal of Long-Lived  Assets." SFAS No. 144 supersedes  previous
guidance for financial  accounting  and reporting for the impairment or disposal
of  long-lived  assets and for  segments of a business  to be  disposed  of. The
Company adopted SFAS No. 144 on January 1, 2002. The adoption of SFAS No. 144 is
not expected to have an impact on the Company's financial position or results of
operations.


Note 2:   Short-term investments

     Short-term  investments  at  December  31,  2001 and  2000,  consisting  of
corporate, state and municipal securities, were acquired at an aggregate cost of
$101.0 million and $78.3 million,  respectively.  The contractual  maturities of

     As of December  31,  2001,  fourteen  of the  Company's  subsidiaries  have
available, for income tax purposes,  foreign net operating loss carryforwards of
approximately $6.5 million, of which $1.1 million expire during the years 2003 -
2010 and $5.4 million of which may be carried forward indefinitely.

     The  Company  has  not  provided  for  U.S.   federal  income  and  foreign
withholding   taxes  on   approximately   $8.0   million  of  certain   non-U.S.
subsidiaries'  undistributed  earnings as of December 31, 2001.  These  earnings
would  become  subject  to taxes of  approximately  $1.6  million,  if they were
actually or deemed to be remitted to the parent  company as  dividends or if the
Company  should  sell its stock in these  subsidiaries.  The  Company  currently
intends to reinvest indefinitely these undistributed earnings.


Note 7:   Acquisition

     On August 31, 1999, the Company  acquired all of the issued and outstanding
shares of common stock of GfS Systemtechnik GmbH and related companies for $12.8
million. The acquisition was accounted for as a purchase. The Company recorded a
$2.1  million  pre-tax  charge  against  earnings in 1999 for the  write-off  of
in-process  GfS research  and  development  technology  that had not reached the
working  model stage.  The Company  also  recorded  $1.1 million of  capitalized
software  development  costs  and  $7.7  million  of  goodwill  related  to  the
acquisition,   which  are  included  in  intangibles   and  other  assets.   The
consolidated financial statements include the operating results from the date of
acquisition. Pro-forma results of operations have not been presented because the
effects of those operations were not material.

                                     -F13-


Note 8:   Stockholders' equity

     Common stock

     On July 22, 1999,  the Company  declared a stock split effected in the form
of a dividend of one share of common  stock for each two shares of common  stock
outstanding. The dividend was paid on August 20, 1999 to holders of record as of
the close of business on August 5, 1999. All share  information  included in the
accompanying  consolidated financial statements and notes has been retroactively
adjusted to reflect the exchange and stock split.

     Stock repurchases and retirements

     In 1998,  the  Company's  Board of Directors  approved the  repurchase  and
retirement  of shares  of common  stock to  reduce  the  dilutive  effect of the
Company's  stock plans.  Pursuant to this  repurchase  program,  the Company has
repurchased  and  retired  a total of  121,800  shares  for  approximately  $3.5
million.

     Stock-based compensation plans

     At December 31, 2001, 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. 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 would have been
reduced by $14.1 million, $10.9 million and $6.5 million in 2001, 2000 and 1999,
respectively. The pro-forma effect on basic earnings per share would have been a
reduction of $0.28,  $0.22 and $0.13 in 2001, 2000 and 1999,  respectively.  The
pro-forma  effect on diluted  earnings  per share would have been a reduction of
$0.26, $0.20 and $0.13 for 2001, 2000 and 1999, respectively.

                                     -F14-


     Stock option plans

     The  stockholders  of the Company  approved the 1994 Incentive Stock Option
Plan on May 9, 1994. At the time of approval,  6,075,000 shares of the Company's
common stock were reserved for issuance  under this plan. In 1997, an additional
4,725,000  shares of the Company's common stock were reserved for issuance under
this plan.  The 1994 Plan,  administered  by the  Compensation  Committee of the
Board of  Directors,  provides for  granting of incentive  awards in the form of
stock options to directors,  executive officers and employees of the Company and
its subsidiaries.  Awards under the plan must be granted within ten years of the
effective date of the 1994 Plan.  Options granted may be either  incentive stock
options  within the  meaning  of Section  422 of the  Internal  Revenue  Code or
nonqualified options. The right to purchase shares vests over a five to ten-year
period,  beginning on the date of grant.  Stock options must be exercised within
ten years from date of grant.  Stock  options are issued at market  price at the
grant date. Shares available for grant at December 31, 2001 were 1,997,740.

     Transactions under all plans are summarized as follows:

  Employee stock purchase plan

     The Company's stock purchase plan became  effective March 13, 1995 upon the
first date of  registration  of the  Company's  common  stock.  The plan permits
substantially all domestic employees and employees of designated subsidiaries to
acquire the  Company's  common stock at a purchase  price of 85% of the lower of
the market price at the beginning or the end of the  participation  period.  The
semi-annual  periods begin on October 1 and April 1 of each year.  Employees may
designate  up to 15% of their  compensation  for the  purchase of common  stock.
Common stock reserved for future employee purchases  aggregated 2,183,283 shares
at December 31, 2001.  Shares  issued under this plan were 278,469 in 2001.  The

     Stockholders' rights plan

     The Board of  Directors  and  stockholders  approved and adopted the Rights
Agreement prior to the Company's  initial public offering (the  "offering").  On
March 13,  1995,  the  effective  date of the  offering,  the Board of Directors
declared a dividend  distribution  of one common share  purchase  right for each
outstanding  share of Common Stock. The rights become  exercisable under certain
conditions  involving  acquisition of the Company's Common Stock.  Under certain
other conditions  where the Company is consolidated or merged,  each holder of a
right shall have the right to  receive,  upon  exercise of the right,  shares of
Common Stock of the Company,  or acquiring company,  having a value of twice the
exercise  price of the right.  The rights  expire on March 13, 2005,  and may be
redeemed in whole by the Company  for $0.01 per right.  The rights are  excluded
from earnings per share  computations  because they qualify as contingent shares
and therefore are excluded as long as the  conditions  that require  issuance of
the shares are not imminent.

                                     -F16-


Note 9:   Employee retirement plan

     The Company has a defined contribution  retirement plan pursuant to Section
401(k) of the Internal Revenue Code.  Substantially all domestic  employees with
at least one year of  continuous  service are  eligible to  participate  and may
contribute up to 15% of their  compensation.  The Board of Directors has elected
to make matching contributions equal to 50% of employee contributions, which may
be  applied,  to a maximum  of 6% of each  participant's  compensation.  Company
contributions vest immediately. The Company's policy prohibits participants from
direct   investment   in  shares  of  common  stock  of  the  Company.   Company
contributions  charged to  expense  were $1.6  million,  $1.3  million  and $1.1
million in 2001, 2000 and 1999, respectively.


Note 10:   Financial instruments

     Fair value of financial instruments

     The estimated fair value amounts  disclosed  below have been  determined by
the Company using  available  market  information  and  valuation  methodologies
described  below.  However,  considerable  judgment is required in  interpreting
market data to develop these estimates of fair value. Accordingly, the estimates
presented herein are not necessarily  indicative of the amounts that the Company
could  realize  in a  current  market  exchange.  The  use of  different  market
assumptions  could  have a  significant  effect on the  estimates.  For  certain
financial  instruments  of the  Company,  including  cash and cash  equivalents,
accounts  receivable,  accounts  payable and accrued  liabilities,  the carrying
amount  approximates  fair  value  due  to  the  short-term  maturity  of  these
instruments.  The estimated fair values of the other assets (liabilities) of the
Company's remaining  financial  instruments at December 31, 2001 and 2000 are as
follows (in thousands):

                                                    December 31,

    Purchased options.........        2,873       2,873         871         871

     The fair values of short-term  investments and foreign currency forward and
purchased  option  contracts were estimated based upon quotes from brokers as of
the applicable balance sheet date.


Note 11:   Derivative instruments and hedging activities

     The Company has operations in over 30 countries.  Forty-nine percent of the
Company's revenues are generated outside North America. The Company's activities
expose it to a variety  of market  risks,  including  the  effects of changes in
foreign-currency  exchange rates and interest  rates.  These financial risks are
monitored  and managed by the Company as an  integral  part of its overall  risk
management program.

     The Company maintains a foreign-currency risk management strategy that uses
derivative   instruments   (foreign   currency  forward  and  purchased  options
contracts) to protect its interests from fluctuations in earnings and cash flows
caused  by  the   volatility   in  currency   exchange   rates.   Movements   in
foreign-currency  exchange  rates pose a risk to the  Company's  operations  and
competitive position,  since exchange rate changes may affect the profitability,
cash flow, and business and/or pricing strategies of non-U.S. based competitors.


     Foreign currency fair value and cash flow hedges

     The  Company's  foreign  sales  are  denominated  in the  customers'  local
currency.  The Company  purchases foreign currency forward and purchased options
contracts  as  hedges  of  forecasted  sales  that are  denominated  in  foreign
currencies  and as hedges of foreign  currency  denominated  receivables.  These
contracts  are  entered  into to  protect  against  the risk  that the  eventual
dollar-net-cash  inflows  resulting from such sales or firm  commitments will be
adversely affected by changes in exchange rates.

     At December 31, 2001,  the Company held  forward  contracts  with  notional
amounts  totaling  $31.9 million that were  designated as foreign  currency fair
value hedges of the Company's foreign denominated receivables.  These contracts,
which are for 90-day periods, had a fair value of $289,000. The Company recorded
a net gain of $2.0 million for fair value hedges for the year ended December 31,
2001, which was recorded in "Foreign Currency Gain(Loss)." The Company hedges up
to 90% of its outstanding foreign denominated receivables.

                                     -F17-


     At December 31, 2001,  the Company held forward  contracts  with a notional
amount of $17.1  million and option  contracts  with notional  amounts  totaling
$54.1 million that were designated as foreign  currency cash flow hedges related
to the Company's anticipated sales transactions.  These contracts, which are for
terms up to  twenty-four  months,  had a fair  value of $4.2  million  and a net
unrealized  deferred  gain  of  $4.2  million  recorded  in  "Accumulated  Other
Comprehensive  Income."  The Company  hedges up to 100% of  anticipated  foreign
currency  denominated cash inflows for the following 1 to 36 months. The Company
recorded  a net gain of $4.4  million  for cash flow  hedges  for the year ended
December 31, 2001, which was included in "Net Revenue."

     As of December 31, 2001, $9.0 million of deferred gains on cash flow hedges
recorded  in  "Accumulated  Other  Comprehensive  Income"  are  expected  to  be
reclassified to earnings during the next twelve months. The actual foreign sales
expected to occur over the next twelve months will necessitate the reclassifying
to earnings of these derivative gains.

     Hedge ineffectiveness of a foreign currency option contract designated as a
cash flow hedge is measured by  comparing  the hedging  instrument's  cumulative
change in fair value from inception to maturity to the forecasted  transaction's
terminal  value.  As of December 31, 2001,  no amounts  were  excluded  from the
assessment of hedge  effectiveness.  For the year ended  December 31, 2001,  the
Company recognized a net gain of $174,000 (reported in the "Net Foreign Exchange
Gain/(Loss)"  line  item  in  the  Consolidated   Statement  of  Income),  which
represented the net ineffectiveness of all cash-flow hedges.


Note 12:   Segment information

     In  accordance  with  SFAS  No.  131,  "Disclosures  about  Segments  of an
Enterprise and Related  Information," the Company determines  segments using the
management   approach.   The   management   approach   designates  the  internal
organization  that is used by  management  for making  operating  decisions  and
assessing  performance as the source of the Company's  reportable  segments.  It
also requires  disclosures  about  products and services,  geographic  areas and
major customers.

     While the Company  sells its  products to many  different  industries,  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 thousands):

Note 13:   Commitments and contingencies

     The Company has commitments under noncancelable  operating leases primarily
for office  facilities  and  equipment.  Future  minimum  lease  payments  as of
December  31,  2001,  for  each  of the  next  five  years  are as  follows  (in
thousands):

        2002.........................................    $1,654
        2003.........................................     1,478

                                                         $5,434
                                                         ======

     Rent expense under operating leases was  approximately  $5.4 million,  $3.5
million and $3.6 million for the years ended  December 31, 2001,  2000 and 1999,
respectively.

     As  of  December  31,  2001,  the  Company  has   non-cancelable   purchase
commitments  with  various  suppliers  of  customized  inventory  and  inventory
components totaling approximately $6.0 million over the next twelve months.

     As of December 31, 2001, the Company has outstanding guarantees for payment
of foreign operating leases,  customs and foreign grants totaling  approximately
$3.2 million.


Note 14:   Litigation

     During 2000, the Company was served by Cognex Corporation, asserting patent
infringement  of  two  Cognex   patents,   copyright   infringement,   trademark
infringement and unfair competition.  Cognex sought permanent injunctive relief,
actual monetary damages in an unspecified  amount and attorney's fees and costs.
The Company  filed a response to the lawsuit  denying all claims.  In the fourth
quarter of 2000, the Company  accrued $2.5 million of  anticipated  intellectual
property  defense  costs that were probable of being  incurred.  The Company and
Cognex  settled the  dispute and Cognex  dismissed  the case with  prejudice  on
August 13, 2001.

     During 2001, the Company filed a complaint in U.S. District Court,  Western
District of Texas (Midland  Division) for  declaratory  judgment  arising from a
controversy between the Company and General Patent  Corporation,  General Patent
Corporation   International,   and  Acticon  Technologies,   LLC  ("Defendants")
concerning the enforceability,  validity, and infringement of certain patents in
which Defendants claim an interest.  Defendants claim that the Company infringes
these patents.  The Company  challenges the validity and enforceability of these
patents and asserts that it does not infringe the claims of these  patents.  The
Company  seeks  a  declaratory  judgment  of  invalidity  and  non-infringement.
Defendants  seek damages in an  unspecified  amount,  injunction  of the sale of
certain  products  of the  Company and  attorney's  fees and costs.  The case is
currently  in  discovery  and trial is set for May 5, 2003.  Due to the inherent
uncertainties of litigation, there can be no assurance that this litigation will
not cause significant liability and a diversion of management's  attention which
may have a material adverse effect on results of operations.

     During 2001,  as a result of the  aforementioned  Cognex  dismissal and the
General  Patent  Corporation  matter,  the Company has reduced its  intellectual
property defense cost accrual by approximately $1.2 million.

                                     -F19-


Note 15:   Related party transactions

     During  2001,  the  Company  acquired a 10%  minority  interest  in another
company for $2.5 million.  Because of the Company's ownership percentage and its
lack of  control  and  inability  to exert  influence  over  this  entity,  this
investment is accounted for under the cost method.  Sales to this company during
2001 were $96,000.  The Company has no other  minority  investments in any other
entities.


Note 16:   Quarterly results (unaudited)

     The  following   quarterly   results  have  been  derived  from   unaudited
consolidated  financial  statements that, in the opinion of management,  reflect
all adjustments  (consisting only of normal recurring adjustments) necessary for
a fair presentation of such quarterly information. The operating results for any
quarter are not  necessarily  indicative  of the results to be expected  for any
future  period.  The unaudited  quarterly  financial  data for each of the eight
quarters in the two years ended  December 31, 2001 are as follows (in thousands,
