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." 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 under the trading symbol NATI. Our Internet website address is http://www.ni.com. Our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 are available through our Internet website as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. Our Internet website and the information contained therein or connected thereto are not intended to be incorporated into this Annual Report on Form 10-K. 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, as well as physical phenomena, such as temperature, pressure, speed, flow, volume, torque and vibration. Common general-purpose instruments include voltmeters, signal generators, oscilloscopes, dataloggers, spectrum analyzers, cameras, and temperature and pressure monitors and controllers. Some traditional instruments are also highly application specific, designed to measure specific signals for particular vertical industries or applications. Instruments used for industrial automation applications include data loggers, strip chart recorders, programmable logic controllers (PLCs), and proprietary turn-key devices and/or systems designed to automate specific vertical applications. Instrument applications can be generally categorized as either T&M or IA. T&M applications generally involve testing during the research, 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. 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. 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. The Company's Approach to Measurement and Automation A virtual instrument is a user-defined measurement and automation system that consists of an industry standard computer (which may be a mainstream general-purpose computer, workstation, handheld PDA device, or a version of an industry standard computer, workstation, or handheld PDA that is specially designed and packaged for harsh industrial or embedded environments) 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 and automation 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 together with industrial automation capabilities. 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 the efficiency and precision of applications spanning research, design, production and service. 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, PDAs, networks and the Internet to instrumentation. With features such as graphical programming, automatic code generation capabilities, graphical tools libraries, ready-to-use example programs, libraries of specific instrumentation functions, and the ability to deploy their applications on a range of platforms, users can quickly build a virtual instrument system that meets their individual application needs. In addition, the continuous improvement in performance of PC and networking technologies, 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, 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. 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, portable PDAs and other handheld devices, as well as ruggedized industrial computers 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. Strategy The Company's objective is to be a leading supplier of measurement and automation products and solutions to engineers, scientists and others in both T&M and IA applications. To achieve this objective, the Company is pursuing a strategy that includes the following elements: Expand Broad Customer Base Serve a Large and Diverse Market.

Leverage External and Internal Technology Leverage Generally Available Technology. The Company leverages the research and development efforts of vendors of personal computers, workstations, PDAs and other handheld devices, operating systems, programming languages and software development tools, and their suppliers. In addition, the Company leverages the research and development efforts of semiconductor vendors by using analog-to-digital converters and other chipsets that are used in a wide variety of high-volume consumer electronics products as components on many of the Company's own measurement and automation hardware products. By integrating Web, networking and communications capabilities directly in its software and hardware products, the Company's products allow users to easily distribute measurement and automation capabilities throughout factories and around the world, easily integrate measurement and automation data throughout their organization and across the enterprise and achieve advanced solutions at a lower development cost. Support Open Architecture on Multiple Platforms. The Company approaches the market with an open architecture so users have the flexibility to combine the Company's products with those from instrument suppliers, computer vendors and competitors. Leverage Core Technologies. The Company designs proprietary Application Specific Integrated Circuits ("ASICs") to optimize performance and reduce production costs. The Company utilizes these ASICs and its other internally developed hardware and software components in multiple products to achieve consistency and compatibility between products. Products and Technology The Company offers an extensive line of measurement and automation products. The Company's products consist of application software, and hardware components together with related driver software. The Company's products are designed to work either in an integrated solution or separately; however, customers generally purchase software and hardware together. 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, LabVIEW Real-Time, LabVIEW FPGA, Measurement Studio, LabWindows/CVI, DIAdem, TestStand, and MATRIXx. 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, LabWindows/CVI, and Measurement Studio are programming environments with which users can develop graphical user interfaces ("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, LabWindows/CVI and Measurement Studio also have ready-to-use libraries for controlling thousands of programmable instruments, including the Company's hardware products, as well as traditional serial, GPIB and VXI measurement and automation devices from other vendors. The principal difference between LabVIEW, LabWindows/CVI, 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 LabVIEW Real-Time, the user's application program can be easily configured to execute using a real-time operating system kernel instead of the Windows operating system, which allows users to easily build virtual instrument solutions for mission-critical applications that require highly reliable operation. In addition, with LabVIEW Real-Time, users can easily configure their programs to execute remotely on embedded processors inside PXI systems, on embedded processors inside Fieldpoint distributed I/O systems, or on processors embedded on plug-in PC data acquisition boards. With LabVIEW FPGA, the user's application can be configured to execute directly in silicon via a Field Programmable Gate Array (FPGA) residing on one of the Company's reconfigurable I/O hardware products. LabVIEW FPGA allows users to easily build their own highly specialized, custom hardware devices for ultra high-performance requirements or for unique or proprietary measurement or control protocols. With LabWindows/CVI, users program using the conventional, text-based language of C. Measurement Studio consists of measurement and automation add-on libraries and additional tools for programmers that use Microsoft's Visual Basic, Visual C++, Visual C#, and Visual Studio.NET development environments. 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, LabWindows/CVI, Measurement Studio, C and C++, and Visual Basic, 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. Hardware Products and Related Driver Software The Company's hardware and related driver software products include data acquisition ("DAQ"), PXI, image acquisition, motion control, FieldPoint Distributed I/O and Embedded Control Hardware/Software, industrial communications interfaces, GPIB interfaces, and VXI Controllers. 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. 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. 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. In essence, PXI is an instrumentation PC with several 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. The Company continues to expand its PXI product offerings with new modules, which address a wide variety of measurement and automation applications. PXI also continues to gain acceptance, with endorsements from over 50 suppliers. Machine Vision/Image Acquisition. In 1996, the Company introduced its first image acquisition hardware which provides users with a cost-effective solution 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, LabWindows/CVI, Visual Basic, C, and Measurement Studio. In 2002, the Company expanded its software offering with new easy-to-use menu driven machine vision software that can run as a stand-alone vision system. The new software can also generate LabVIEW code. In 2003, the Company introduced its new Vision Builder software for automated inspection and its new Compact Vision System, which is a small, ruggedized, industrial vision system that can connect up to three IEEE-1394 cameras and that is easily programmed using Vision Builder. 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, LabWindows/CVI 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. FieldPoint Distributed I/O and Embedded Control Hardware/Software. FieldPoint is an intelligent, distributed, and modular I/O system, first introduced by the Company in 1997, 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, driver libraries for support under LabVIEW, LabWindows/CVI, Measurement Studio and other industrial automation software packages. With LabVIEW Real-Time users can download their LabVIEW code and easily create networked systems of intelligent, real-time nodes for embedded measurement and control. In late 2002, the Company launched Compact FieldPoint, a new intelligent distributed I/O product line with 23 new measurement and automation modules. Compact FieldPoint is also an execution target for LabVIEW Real-Time, and its smaller size and even more rugged form factor further extends NI's hardware and LabVIEW Real-Time into new industrial control, process monitoring, and embedded machine applications that require intelligent I/O products with a small form factor, a wide operating temperature, and resistance to shock and vibration. 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. GPIB Interfaces/Driver Software. 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. 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), Ethernet, and serial ports. VXI Controllers//Driver Software. The Company is a leading supplier of VXI computer controller hardware and the accompanying NI-VXI and NI-VISA driver software.

The Company actively markets its products in higher education environments, and identifies many colleges, universities and trade and technical schools as key accounts. The Company offers special academic pricing and products to enable universities to utilize Company products in their classes and laboratories. The Company believes its prominence in the higher education area can contribute to its future success because students gain experience using the Company's products 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 53%, 50%, and 49% of the Company's revenues in 2003, 2002, and 2001, respectively. The Company expects that a significant portion of its total revenues will continue to be derived from international sales. See Note 11 of Notes to Consolidated Financial Statements for details concerning the geographic breakdown of the Company's net sales, operating income and identifiable assets. 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 hardward products. Historically, warranty costs have not been material. The Company's foreign operations are subject to certain risks set forth on page 21 under "Risks Associated with International Operations and Foreign Economies." 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. 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. 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 severe weather, natural disasters and government actions throughout the world. Although the Company operates in a highly competitive market, it believes it competes favorably with respect to these factors of competition. There can be no assurance that the Company will be able to compete successfully in the future. Research and Development The Company believes that its long-term growth and success depends 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. As of December 31, 2003, the Company employed 852 people in product research and development. The Company's research and development expenses were $70.9 million, $64.0 million, and $60.7 million for 2003, 2002, and 2001, 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, 2003, the Company held 202 United States patents (198 utility patents and 4 design patents) and 33 patents in foreign countries (30 patents registered in Europe in various countries; 1 patent in Canada; and 2 patents in Japan), and had 265 patent applications pending in the United States and foreign countries. 46 of such issued 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 2021. 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. Manufacturing and Suppliers The Company manufactures a substantial majority of its products at its facilities in Austin, Texas and Debrecen, Hungary. 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. 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 "Management's 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, 2003, the Company had 3,078 employees, including 852 in research and development, 1,406 in sales and marketing and customer support, 466 in manufacturing and 354 in administration and finance. None of the Company's employees are represented by a labor union and the Company has never experienced a work stoppage. The Company considers its employee relations to be good. For five consecutive years, 1999, 2000, 2001, 2002, and 2003, the Company has been named among the 100 Best Companies to Work for in America according to FORTUNE magazine. ITEM 2. PROPERTIES The Company's principal 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, a 140,000 square foot manufacturing and office facility, and a 380,000 square foot research and development facility. The Company also owns a 136,000 square foot office building in Austin, Texas which is being leased to a third-party. The Company also owns a 148,000 square foot manufacturing facility in Debrecen, Hungary. 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, which is partially leased to BMS Modern Games and Klocke Nanotech. As of December 31, 2003, the Company also leased a number of sales and support offices in the United States and overseas. The Company's facilities are currently utilized below design maximum capacity to allow for headcount growth and design/construction cycles. The Company believes existing facilities are adequate to meet its current requirements. ITEM 3. LEGAL PROCEEDINGS The Company has filed two complaints against The MathWorks, Inc. ("Defendant") for patent infringement. In both complaints, the Company claimed the Defendant infringes certain of its U.S. patents and the Defendant challenged the validity and enforceability of those patents and asserts that it does not infringe the claims of those patents. The first complaint was filed on January 25, 2001 in the U.S. District Court, Eastern District of Texas (Marshall Division). On January 30, 2003, the jury found infringement by the Defendant of three of the patents involved and awarded the Company specified damages. On June 23, 2003, the Court entered final judgment in favor of the Company in an amount of approximately $4 million and entered an injunction against Defendant's sale of its Simulink and related products. The Court stayed the injunction pending appeal of the case and required the Defendant to pay a specified royalty on its U.S. sales of the same products during the pendency of appeal. The initial judgement and the royalties on the sales of infringing products through December 31, 2003, total $4.9 million and are escrowed. On July 22, 2003, Defendant filed its Notice of Appeal and the case is currently pending on appeal before the U.S. Court of Appeals for the Federal Circuit. The final judgment has not been recorded in the financial statements of the Company pending the disposition of the appeal. The second complaint was filed October 21, 2002, also in the U.S. District Court, Eastern District of Texas (Marshall Division) and on August 27, 2003, the complaint was dismissed by agreement of the parties. On January 15, 2003, SoftWIRE Technology, LLC ("SoftWIRE") and Measurement Computing Corporation ("MCC") filed a complaint against the Company in the U.S. District Court for the District of Massachusetts asking the court to declare that SoftWIRE does not infringe certain of the Company's U.S. patents and that such patents are invalid and unenforceable. On February 21, 2003, the Company filed a complaint against SoftWIRE and MCC in the U.S. District Court, Eastern District of Texas (Marshall Division) claiming that both SoftWIRE and MCC infringe the same and certain other of the Company's U.S. patents. SoftWIRE and MCC challenge the validity and enforceability of these patents and assert that they do not infringe any of these patents. In the Eastern District action, the Company seeks monetary damages and injunction of the sale of certain products of SoftWIRE and MCC as well as attorney's fees and costs. By order of the Court, the Eastern District action was transferred to the U.S. District Court for the District of Massachusetts on May 9, 2003, and has been consolidated with the previously-filed SoftWIRE action, which also includes counterclaims by the Company that are the same in substance as the Company's claims in the Eastern District action. On June 12, 2003, SoftWIRE moved for leave to amend its complaint in order to allege that the Company infringes two U.S. patents that SoftWIRE acquired by purchase on May 23, 2003. On November 5, 2003, the Court granted SoftWIRE's motion to amend, thereby adding SoftWIRE's two patents to the litigation. With respect to those two SoftWIRE patents, SoftWIRE seeks monetary damages and injunction of the sale of certain products of the Company as well as attorney's fees and costs. The Company challenges the validity, enforceability and alleged infringement of those patents and intends to vigorously defend against SoftWIRE's claims. Discovery in the litigation is underway. During the fourth quarter of 2003, the Company accrued $3.8 million related to its probable loss from this contingency, which consists solely of anticipated patent defense costs that are probable of being incurred. However, the outcome of any litigation is inherently uncertain and there can be no assurance as to the ultimate outcome of this matter or any other litigation. The Company did not make any charges against this accrual during calendar 2003. 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.

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 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 for the two most recent fiscal years, are as indicated in the following table. High Low 2003 First Quarter 2003...................................... $37.01 $31.81 Second Quarter 2003..................................... 39.15 29.36 Third Quarter 2003...................................... 43.78 35.60 Fourth Quarter 2003..................................... 46.93 39.94 High Low 2002 First Quarter 2002...................................... $42.62 $34.12 Second Quarter 2002..................................... 41.75 30.21 Third Quarter 2002...................................... 31.50 21.56 Fourth Quarter 2002..................................... 36.46 20.00 At the close of business on January 20, 2004, there were approximately 600 holders of record of the Common Stock and approximately 13,000 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, changes in earnings estimates by analysts or changes in the Company's financial guidance 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. The Company paid cash dividends of $0.05 per share each on August 29, 2003 and November 24, 2003. Prior to this, the Company had not paid any cash dividends on its Common Stock. On October 24, 2003, the Company issued an aggregate of 24,000 shares of its common stock (together with cash) in connection with its acquisition of the outstanding shares of a privately held company. The shares were issued to the shareholders of the acquired company pursuant to Section 4(2) under the Securities Act of 1933 based on representations and warranties obtained from the persons to whom the shares were issued. See Item 12 for information regarding securities authorized for issuance under equity compensation plans.

We use words such as "anticipate," "believe," "plan," "expect," "future," "intend," "may," "will," "project," "continue," "estimate" and similar expressions to identify forward-looking statements. Our actual results could differ materially from the results anticipated in these forward-looking statements. As a result of certain factors including those set forth under the heading "Factors affecting the Company's Business and Prospects" beginning on page 19, and elsewhere in this Form 10-K. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. You should not place undue reliance on these forward-looking statements. We disclaim any obligation to update information contained in any forward-looking statement. Overview National Instruments 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 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 traditional instruments. In IA 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 2003, 2002 or 2001. 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. Results of Operations The following table sets forth, for the periods indicated, the percentage of net sales represented by certain items reflected in the Company's consolidated statements of income: Years Ended December 31, 2003 2002 2001 -------- -------- -------- Net sales: North America.................................. 47.0% 50.1% 50.8% Europe......................................... 32.4 31.4 33.4 Asia Pacific................................... 20.6 18.5 15.8 -------- -------- -------- Consolidated net sales......................... 100.0 100.0 100.0 Cost of sales...................................... 26.2 26.9 26.3 -------- -------- -------- Gross profit................................... 73.8 73.1 73.7 Operating expenses: Sales and marketing............................ 37.7 37.3 37.8 Research and development....................... 16.6 16.4 15.8 General and administrative..................... 10.0 9.1 7.5 -------- -------- -------- Total operating expenses.................... 64.3 62.8 61.1 -------- -------- -------- Operating income............................ 9.5 10.3 12.6 Other income (expense): Interest income................................ 0.6 0.8 1.5 Interest expense............................... -- -- -- Net foreign exchange gain (loss) and other..... 0.3 -- (0.2) -------- -------- -------- Income before income taxes......................... 10.4 11.1 13.9 Provision for income taxes......................... 2.6 3.1 4.5 -------- -------- -------- Net income......................................... 7.8% 8.0% 9.4% ======== ======== ======== Net Sales. In 2003, net sales for the Company's products were $425.9 million, a 9% increase from the level achieved in 2002, which followed an increase in net sales of 1% in 2002 from the level achieved in 2001. The Company believes the increase in sales in 2003 is primarily attributable to the introduction of new and upgraded products, an early stage recovery in the global economy and an increased market acceptance of the Company's products in Asia. The Company believes the increase in sales in 2002 was primarily attributable to the introduction of new and upgraded products and an increased market acceptance of the Company's products in Asia. Sales in North America increased 2% to $200.2 million in 2003 compared to 2002. North America sales in 2002 were flat with sales in 2001. Sales outside of North America, as a percentage of consolidated sales for 2003, increased to 53.0% from 49.9% in 2002, as a result of stronger sales in Asia Pacific and a stronger Euro. European revenue was $137.8 million in 2003, an increase of 12% from 2002, following a 4% decrease in 2002 from 2001. Asia Pacific revenue grew 22% to $87.9 million in 2003, which followed a 19% increase in 2002 over 2001 levels. The Company expects sales outside of North America to continue to represent a significant portion of its revenue. The Company intends to continue to expand its international operations by increasing its presence in existing markets, adding a market presence in some new geographical markets and continuing the use of 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 foreign currency exchange rates. Between 2003 and 2002, net of hedging results, the change in the exchange rates had the effect of increasing the Company's consolidated sales by 2.5%, increasing European sales by 13% and decreasing sales in Asia Pacific by 13%. The increase in sales in Europe as a result of the change in exchange rates was partially offset by the decrease in local currency product pricing in Europe. Since most of the Company's international operating expenses are also incurred in local currencies, the change in exchange rates had the effect of increasing operating expenses $6.5 million, or 2.4%, in 2003 and $4.5 million, or 1.9%, in 2002, and decreasing operating expenses $2.0 million, or 0.9%, in 2001. Gross Profit. As a percentage of sales, gross profit represented 74%, 73% and 74% in 2003, 2002 and 2001, respectively. The increase in gross margin in 2003 compared to the prior year is primarily attributable to favorable foreign currency exchange rates and the favorable impact of higher sales volume. There can be no assurance that the Company will maintain its historical margins. The Company believes its current manufacturing capacity is adequate to meet current needs. Sales and Marketing. Sales and marketing expense in 2003 increased to $160.5 million, a 10% increase from 2002. Sales and marketing expenses in 2002 were flat with 2001. Sales and marketing expense as a percentage of revenue was 38% in 2003, up from 37% in 2002 and flat with 38% in 2001. Approximately $9.1 million of the increase in sales and marketing expenses in 2003 compared to 2002 is attributable to the increase in international sales and marketing personnel costs, and approximately $5.4 million of the increase is attributable to increases in advertising and literature costs and special event activity. The Company expects sales and marketing expenses in future periods to increase in absolute dollars, and to fluctuate as a percentage of sales based on recruiting, initial marketing and advertising campaign costs associated with major new product releases and entry into new market areas, investment in web sales and marketing efforts, increasing product demonstration costs and the timing of domestic and international conferences and trade shows. Research and Development. Research and development expense in 2003 increased 11% compared to 2002 following an increase of 5% in 2002 over 2001. The increase in research and development costs in each period was primarily due to increases in personnel costs from hiring of additional product development engineers. Research and development personnel increased from 791 at December 31, 2002 to 852 at December 31, 2003. The Company plans to continue making a significant investment in research and development in order to remain competitive and support revenue growth. The Company capitalizes software development costs in accordance with 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 $5.6 million, $3.8 million and $3.1 million during 2003, 2002 and 2001, respectively. Software development costs capitalized during such years were $10.7 million, $5.8 million and $3.9 million, respectively. (See Note 5 of Notes to Consolidated Financial Statements for a description of intangibles.) General and Administrative. General and administrative expenses in 2003 increased 19% from 2002, which followed an increase of 22% in 2002 from 2001. The increase in general and administrative expenses in 2003 from 2002 is primarily attributable to the upgrade of the Company's America's business applications suite to Oracle's latest web-based release 11i, continued investment in the Company's web and e-commerce offerings and $8.0 million for patent litigation. The patent litigation expense consisted primarily of a $3.8 million charge recorded in the fourth quarter of 2003 for the probable loss resulting solely from anticipated patent defense costs related to the legal action brought against the Company by SoftWIRE Technology, LLC ("SoftWIRE") and Measurement Computing Corporation ("MCC"), and $3.8 million associated with the legal action brought by the Company against The MathWorks. (See Note 13 of Notes to Consolidated Financial Statements.) The increase in general and administrative expenses in 2002 from 2001 is attributable to increased litigation costs of $4.7 million associated with a legal action brought by the Company against The MathWorks, Inc. in 2001 to enforce the Company's intellectual property rights, compared to a net gain of approximately $1.2 million in 2001 recorded as a result of the receipt of unexpected insurance proceeds from a case with Cognex Corporation. General and administrative expenses as a percentage of revenue increased to 10.0% during 2003 from 9.1% during 2002. The Company expects that general and administrative expenses in future periods will fluctuate in absolute amounts and as a percentage of revenue. During 2002, the Company and Trilogy Software, Inc. ("Trilogy") settled a dispute regarding Trilogy's buy-out of the lease of the Company's Millenium office building which resulted in a gain of approximately $6.0 million from lease termination. As a result of additional facility lease consolidation, the Company incurred lease termination costs of approximately $2.4 million in 2002. In 2002, the Company irrevocably contributed approximately $3.6 million to the National Instruments Foundation, a 501(c)(3) charitable foundation established in 2002 for the purpose of continued promotion of scientific and engineering research and education at higher education institutions worldwide. Two of the four directors of the National Instruments Foundation are current officers of National Instruments. Interest Income and Expense. Interest income decreased 24% in 2003 from 2002, which followed a decrease of 44% in 2002 from 2001 and a decrease of 9% in 2001 from 2000. The decrease in interest income in each year was due to lower yields on the Company's investments. The primary source of interest income is from the investment of the Company's cash. Net cash provided by operating activities in 2003 totaled $63.9 million. Net Foreign Exchange Gain (Loss). The Company experienced net foreign exchange gains of $1.1 million in 2003, compared to losses of $724,000 in 2002 and losses of $1.4 million in 2001. These results are attributable to movements between the U.S. dollar and the local currencies in countries in which the Company's subsidiaries are located. The Company recognizes the local currency as the functional currency of its international subsidiaries. The Company utilizes foreign currency forward contracts to hedge a majority of its foreign currency-denominated receivables in order to reduce its exposure to significant foreign currency fluctuations. The Company typically limits the duration of its "receivables" foreign currency forward contracts to 90 days. The Company also utilizes foreign currency forward contracts and foreign currency purchased option contracts in order to reduce its exposure to fluctuations in future foreign currency cash flows. The Company purchases these contracts for up to 100% of its forecasted cash flows in selected currencies (primarily the euro, yen and pound sterling) and limits the duration of these contracts to 40 months. The foreign currency purchased option contracts are purchased "at-the-money" or "out-of-the-money." As a result, the Company's hedging activities only partially address its risks in foreign currency transactions, and there can be no assurance that this strategy will be successful. The Company does not invest in contracts for speculative purposes. (See Note 10 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 gains for December 31, 2003 by $11.5 million and increased the net foreign exchange loss for December 31, 2002 by $1.4 million. Provision for Income Taxes. The provision for income taxes reflects an effective tax rate of 25% in 2003, 28% in 2002 and 32% in 2001. The decrease in the effective rate resulted from income tax benefits attributable to the extraterritorial income exclusion and a change in the distribution of income among taxing jurisdictions, particularly the impact of the Company's manufacturing facility in Hungary. The Company's effective tax rate is lower than the U.S. federal statutory rate of 35% primarily as a result of the extraterritorial income exclusion, tax-exempt interest and reduced tax rates in certain foreign jurisdictions. Liquidity and Capital Resources The Company is currently financing its operations and capital expenditures through cash flow from operations. At December 31, 2003, the Company had working capital of approximately $255.3 million compared to $211.5 million at December 31, 2002. Net cash provided by operating activities in 2003, 2002 and 2001 totaled $63.1 million, $49.1 million and $57.2 million, respectively. Accounts receivable increased to $78.0 million at December 31, 2003 from $63.0 million at December 31, 2002, as a result of higher sales levels in the fourth quarter of 2003 compared to the fourth quarter of 2002. Days sales outstanding at December 31, 2003 increased to 58 days from 54 days at December 31, 2002. Consolidated inventory balances have decreased to $38.9 million at December 31, 2003 from $39.2 million at December 31, 2002. Inventory turns of 3.2 per year for 2003 represent an increase from turns of 2.8 per year for 2002. Cash used in 2003 for the purchase of property and equipment totaled $18.0 million, for the capitalization of internally developed software costs totaled $9.7 million, for acquisitions totaled $6.3 million and for additions to other intangibles totaled $2.5 million. Cash used in 2002 for the purchase of property and equipment totaled $30.8 million, for the capitalization of internally developed software costs totaled $5.8 million and for additions to other intangibles totaled $3.0 million. Cash used in 2001 for the purchase of property and equipment totaled $65.3 million, for the capitalization of internally developed software costs totaled $3.9 million and for additions to other intangibles totaled $1.0 million. Cash provided by the issuance of common stock totaled $19.4 million, $13.4 million and $12.2 million in 2003, 2002 and 2001, respectively, and cash used for payment of dividends totaled $5.2 million in 2003. The issuance of common stock was primarily to employees under the Employee Stock Purchase and Stock Option Plans. The following summarizes the Company's contractual cash obligations as of December 31, 2003 (in thousands): -------------------------------------------------------------------- Payments Due by Period -------------------------------------------------------------------- Total 2004 2005 2006 2007 2008 Beyond -------- -------- -------- -------- -------- -------- -------- Long-term debt $ -- $ -- $ -- $ -- $ -- $ -- $ -- Capital lease obligations -- -- -- -- -- -- -- Operating leases 24,686 7,113 5,387 3,202 2,089 881 6,014 Other long-term obligations -- -- -- -- -- -- -- -------- -------- -------- -------- -------- -------- -------- Total contractual cash obligations $ 24,686 $ 7,113 $ 5,387 $ 3,202 $ 2,089 $ 881 $ 6,014 ======== ======== ======== ======== ======== ======== ======== The following summarizes the Company's other commercial commitments as of December 31, 2003 (in thousands): ------------------------------------------------------ Total 2004 2005 2006 2007 2008 Beyond ------ ------ ------ ------ ------ ------ ------ Guarantees $3,500 $3,500 $ -- $ -- $ -- $ -- $ -- Purchase obligations 3,400 3,400 -- -- -- -- -- ------ ------ ------ ------ ------ ------ ------ Total commercial commitments $6,900 $6,900 $ -- $ -- $ -- $ -- $ -- ====== ====== ====== ====== ====== ====== ====== The Company currently expects to fund expenditures for capital requirements as well as liquidity needs created by changes in working capital from a combination of available cash and short-term investment balances and internally generated funds. As of December 31, 2003 and 2002, the Company had no debt outstanding. The Company believes that the cash flow from operations, if any, existing cash balances and short-term investments, will be sufficient to meet its cash requirements for at least the next twelve months. Cash requirements for periods beyond the next twelve months will depend on the Company's profitability, its ability to manage working capital requirements and its rate of growth. Financial Risk Management The Company's international sales are subject to inherent risks, including fluctuations in local economies; difficulties in staffing and managing foreign operations; greater difficulty in accounts receivable collection; costs and risks of localizing products for foreign countries; unexpected changes in regulatory requirements, tariffs and other trade barriers; difficulties in the repatriation of earnings and burdens of complying with a wide variety of foreign laws. The Company's sales outside of North America are denominated in local currencies, and accordingly, the Company is subject to the risks associated with fluctuations in currency rates. In particular, increases in the value of the dollar against foreign currencies decrease the U.S. dollar value of foreign sales requiring the Company either to increase its price in the local currency, which could render the Company's product prices noncompetitive, or to suffer reduced revenues and gross margins as measured in U.S. dollars. These dynamics have adversely affected revenue growth in international markets in previous years. The Company's foreign currency hedging program includes both foreign currency forward and purchased option contracts to reduce the effect of exchange rate fluctuations. However, the hedging program will not eliminate all of the Company's foreign exchange risks. (See "Net Foreign Exchange Gain (Loss)" and Note 10 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 inventories and management continues to monitor the adequacy of such valuation allowances, there can be no assurance that such valuation allowances will be sufficient. The Company has no debt or off-balance sheet debt. As of December 31, 2003, the Company has non-cancelable operating lease obligations of approximately $24.7 million and contractual purchase commitments with various suppliers of general components and customized inventory components of approximately $3.4 million. As of December 31, 2003, the Company has outstanding guarantees for payment of foreign operating leases, customs and foreign grants totaling approximately $3.5 million. (See Note 12 of Notes to Consolidated Financial Statements.) As of December 31, 2003, the Company did not have any relationships with any unconsolidated entities or financial partnerships, such as entities often referred to as structured finance entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. As such, the Company is not exposed to any financing, liquidity, market or credit risk that could arise if the Company were engaged in such relationships. Market Risk The Company is exposed to a variety of risks, including foreign currency fluctuations and changes in the market value of its investments. In the normal course of business, the Company employs established policies and procedures to manage its exposure to fluctuations in foreign currency values and changes in the market value of its investments. Foreign Currency Hedging Activities. The Company's objective in managing its exposure to foreign currency exchange rate fluctuations is to reduce the impact of adverse fluctuations in such exchange rates on the Company's earnings and cash flow. Accordingly, the Company utilizes purchased foreign currency option contracts and forward contracts to hedge its exposure on anticipated transactions and firm commitments. The principal currencies hedged are the euro, British pound and Japanese yen. The Company monitors its foreign exchange exposures regularly to ensure the overall effectiveness of its foreign currency hedge positions. However, there can be no assurance the Company's foreign currency hedging activities will substantially offset the impact of fluctuations in currency exchange rates on its results of operations and financial position. Based on the foreign exchange instruments outstanding at December 31, 2003, an adverse change (defined as 20% in the Asian currencies and 10% in all other currencies) in exchange rates would result in a decline in the aggregate fair market value of all instruments outstanding of approximately $12.0 million. However, as the Company utilizes foreign currency instruments for hedging anticipated and firmly committed transactions, management believes that a loss in fair value for those instruments will be substantially offset by increases in the value of the underlying exposure. (See Note 9 of Notes to Consolidated Financial Statements for a description of the Company's financial instruments at December 31, 2003 and 2002.) Short-term Investments. The fair value of the Company's investments in marketable securities at December 31, 2003 was $141.2 million. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The Company's investment policy is to manage its investment portfolio to preserve principal and liquidity while maximizing the return on the investment portfolio through the full investment of available funds. The Company diversifies the marketable securities portfolio by investing in multiple types of investment-grade securities. The Company's investment portfolio is primarily invested in 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, 2003, a 100 basis point increase or decrease in interest rates would result in a decrease or increase of approximately $700,000, respectively, in the fair value of the investment portfolio. Although changes in interest rates may affect the fair value of the investment portfolio and cause unrealized gains or losses, such gains or losses would not be realized unless the investments are sold. Recently Issued Accounting Pronouncement In May 2003, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity. This Statement establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances) because that financial instrument embodies an obligation of the issuer. This Statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. It is to be implemented by reporting the cumulative effect of a change in an accounting principle for financial instruments created before the issuance date of the Statement and still existing at the beginning of the interim period of adoption. The adoption of SFAS No. 150 did not have a material effect on the Company's financial position or results of operations. Critical Accounting Policies The Company's critical accounting policies are as follows: o Revenue recognition Revenue from the sale and licensing of products is generally 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 the valuation allowance for excess and obsolete inventories The preparation of financial statements requires the Company to make estimates and assumptions that affect the reported amount of assets and liabilities 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 its 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 $1.1 million at December 31, 2003. 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, management must make estimates of the uncollectability of the Company's accounts receivables. Management specifically analyzes accounts receivable and analyzes historical bad debts, customer concentrations, customer credit-worthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. The allowance for doubtful accounts was $2.1 million at December 31, 2003. 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 of future demand and market conditions. The valuation allowance for excess and obsolete inventories was $3.8 million at December 31, 2003. If actual market conditions are less favorable than those projected by management, additional inventory write downs may be required. 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, 2003, unamortized capitalized software development costs was $14.2 million. o Valuation of long-lived and intangible assets The Company assesses the impairment 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, 2003, the Company had net goodwill of approximately $10.3 million. o Accounting for income taxes The Company accounts for income taxes under the asset and liability method that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's financial statements or tax returns. In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. o Loss contingencies The Company accrues for probable losses from contingencies including 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. Factors Affecting the Company's Business and Prospects U.S./Global Economic Slowdown. As occurred in recent years, the markets in which the Company does business could again experience the negative effects of a slowdown in the U.S. and/or Global economies. Additionally, the Company could be impacted by the effects of any recurrence of the SARS virus, either through increased difficulty or costs for the export of products into affected regions, the import of components used in the Company's products from affected regions, and/or the effects the virus or costs to contain the virus have on the economy in regions in which the Company does business, particularly Asia, which has been the highest growth region of the Company over the past two years. The Company could also be subject to or impacted by acts of terrorism and/or the effects that war or continued U.S. military action would have on the U.S. and/or global economies. The worsening of the U.S. or Global economies could result in reduced purchasing and capital spending in any of the markets served by the Company which could have a material adverse effect on the Company's operating results. Budgets. The Company has established an operating budget for 2004. The Company's spending for 2004 could exceed this budget due to a number of factors; including: additional marketing costs for conferences and tradeshows; increased costs from the over-hiring of product development engineers or other personnel; increased manufacturing costs resulting from component supply shortages and/or component price fluctuations and/or additional expenses related to intellectual property litigation. Any future decreased demand for the Company's products could result in decreased revenue and could require the Company to revise its budget and reduce expenditures. Exceeding the established operating budget or failing to reduce expenditures in response to any decrease in revenue could have a material adverse effect on the Company's operating results. Risk of Component Shortages. As has occurred in the past, and as may be expected to occur in the future, supply shortages of components used in our products, including sole source components, can result in significant additional costs and inefficiencies in manufacturing. If the Company is unsuccessful in resolving any such component shortages, it will experience a significant impact on the timing of revenue and/or an increase in manufacturing costs, either of which would have a material adverse impact on the Company's operating results. Fluctuations in Quarterly Results. The Company's quarterly operating results have fluctuated in the past and may fluctuate significantly in the future due to a number of factors, including: changes in the mix of products sold; the availability and pricing of components from third parties (especially sole sources); the timing of orders; level of pricing of international sales; fluctuations in foreign currency exchange rates; the difficulty in maintaining margins, including the higher margins traditionally achieved in international sales; and changes in pricing policies by the Company, its competitors or suppliers. Specifically, if the local currencies in which the Company sells weaken against the U.S. dollar, and if the local sales prices cannot be raised, the Company will experience a deterioration of its gross and net profit margins. If the U.S. dollar strengthens in the future, it could have a material adverse effect on gross and net profit margins. As has occurred in the past and as may be expected to occur in the future, new software products of the Company or new operating systems of third parties on which the Company's products are based, often contain bugs or errors that can result in reduced sales and/or cause the Company's support costs to increase, either of which could have a material adverse impact on the Company's operating results. Furthermore, the Company has significant revenues from customers in industries such as semiconductors, automated test equipment, telecommunications, aerospace, defense and automotive which are cyclical in nature. Downturns in these industries could have a material adverse effect on the Company's operating results. In recent years, the Company's revenues have been characterized by seasonality, with revenues typically being relatively constant in the first, second and third quarters, growing in the fourth quarter and being relatively flat or declining from the fourth quarter of the year to the first quarter of the following year. The Company believes the seasonality of its revenue results from the international mix of its revenue and the variability of the budgeting and purchasing cycles of its customers throughout each international region. In addition, total operating expenses have in the past tended to be higher in the second and third quarters of each year, due to recruiting and increased intern personnel expenses. New Product Introductions and Market Acceptance. The market for the Company's products is characterized by rapid technological change, evolving industry standards, changes in customer needs and frequent new product introductions, and is therefore highly dependent upon timely product innovation. The Company's success is dependent on its ability to successfully develop and introduce new and enhanced products on a timely basis to replace declining revenues from older products, and on increasing penetration in domestic and international markets. In the past, the Company has experienced significant delays between the announcement and the commercial availability of new products. Any significant delay in releasing new products could have a material adverse effect on the ultimate success of a product and other related products and could impede continued sales of predecessor products, any of which could have a material adverse effect on the Company's operating results. There can be no assurance that the Company will be able to introduce new products in accordance with announced release dates, that new products will achieve market acceptance or that any such acceptance will be sustained for any significant period. Failure of new products to achieve or sustain market acceptance could have a material adverse effect on the Company's operating results. Moreover, there can be no assurance that the Company's international sales will continue at existing levels or grow in accordance with the Company's efforts to increase foreign market penetration. Risks Associated with Increased Development of Web Site. The Company has devoted significant resources in developing its Web site as a key marketing and sales tool and expects to continue to do so in the future. There can be no assurance that the Company will be successful in its attempt to leverage the Web to increase sales. The Company hosts its Web site internally. Any failure to successfully maintain the Web site and to protect it from attack could have a significant adverse impact on the Company's operating results. Operation in Intensely Competitive Markets. The markets in which the Company operates are characterized by intense competition from numerous competitors, some of which are divisions of large corporations having far greater resources than the Company, and the Company expects to face further competition from new market entrants in the future. A key competitor is Agilent Technologies Inc. ("Agilent"). Agilent offers its own line of instrument controllers, and also offers hardware and software add-on products for third-party desktop computers and workstations that provide solutions that directly compete with the Company's virtual instrumentation products. Agilent is aggressively advertising and marketing products that are competitive with the Company's products. Because of Agilent's strong position in the instrumentation business, changes in its marketing strategy or product offerings could have a material adverse effect on the Company's operating results. The Company believes its ability to compete successfully depends on a number of factors both within and outside its control, including: new product introductions by competitors; product pricing; quality and performance; success in developing new products; adequate manufacturing capacity and supply of components and materials; efficiency of manufacturing operations; effectiveness of sales and marketing resources and strategies; strategic relationships with other suppliers; timing of new product introductions by the Company; protection of the Company's products by effective use of intellectual property laws; general market and economic conditions; and government actions throughout the world. There can be no assurance that the Company will be able to compete successfully in the future. Management Information Systems. During 2003, the Company successfully upgraded its America's business applications suite to Oracle's latest web-based release 11i. However, there can be no assurance that the Company will not experience difficulties with the new system. Difficulties with the system may interrupt normal Company operations, including the ability to: provide quotes, process orders, ship products, provide services and support to its customers, bill and track its customers, fulfill contractual obligations and otherwise run its business. Any disruptions of the system may have a material adverse effect on the Company's operating results. In 2003, the Company also continued development of its web offerings. In 2004, the Company will be focusing on the upgrade of its European business applications suite to Oracle's latest web-based release 11i, as well as the management information system for the Company's current warehouse facilities, and will continue to devote significant resources to the development of the Company's web offerings. Any failure to successfully implement these initiatives could have a material adverse effect on the Company's operating results. The Company relies on three primary regional centers for its management information systems. As with any information system, unforeseen issues may arise that could affect management's ability to receive adequate, accurate and timely financial information which in turn could inhibit effective and timely decisions. Furthermore, it is possible that one or more of the Company's three regional information systems could experience a complete or partial shutdown. If such a shutdown occurred near the end of a quarter it could impact the Company's product shipments and revenues, as product distribution is heavily dependent on the integrated management information systems in each region. Accordingly, operating results in that quarter would be adversely impacted. The Company is working to achieve reliable regional management information systems to control costs and improve its 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 import and export regulations. Failure to comply with these regulations could result in fines and/or termination of import and export privileges, which could have a material adverse effect on the Company's operating results. Additionally, the regulatory environment in some countries is very restrictive as their governments try to protect their local economy and value of their local currency against the U.S. dollar. Sales made by the Company's international direct sales offices are denominated in local currencies, and accordingly, the U.S. dollar equivalent of these sales is affected by changes in the foreign currency exchange rates. Net of hedging results, the change in exchange rates had the effect of increasing the Company's consolidated sales by $16.5 million, or 4.0%, in 2003 compared to 2002. Since most of the Company's international operating expenses are also incurred in local currencies, the change in exchange rates had the effect of increasing operating expenses by $6.5 million for 2003 compared to 2002. If the U.S. dollar weakens in the future, it could result in the Company having to reduce prices locally in order for its products to remain competitive in the local marketplace. If the U.S. dollar strengthens in the future and the Company is unable to successfully raise its international selling prices, it could have a materially adverse effect on the Company's operating results. Expansion of Manufacturing Capacity. During 2001, the Company completed construction of a second manufacturing facility. This facility is located in Hungary and became operational in the fourth quarter of 2001. This facility sources a significant portion of the Company's sales. Currently the Company is continuing to develop and implement information systems to support the operation of this facility. This facility and its operation are also subject to risks associated with a relatively 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, any failure to deal with these factors could result in interruption in the facility's operation or delays in expanding its capacity, either of which could have a material adverse effect on the Company's operating results. Income Tax Rate. The Company established a manufacturing facility in Hungary in 2001. As a result of certain foreign investment incentives available under Hungarian law, the profit from the Company's Hungarian operation is currently exempt from income tax. These benefits may not be available in the future due to changes in Hungary's political condition and/or tax laws. The reduction or elimination of these foreign investment incentives would result in the reduction or elimination of certain tax benefits thereby increasing the Company's future effective income tax rate, which could have a material adverse effect on the Company's operating results. The Company receives a substantial income tax benefit from the extraterritorial income exemption ("ETI") under U.S. law. The ETI rules provide that a percentage of the profits from products and intangibles exported from the U.S. are exempt from U.S. tax. This benefit may not be available in the future as the ETI has been ruled an illegal export subsidy by the World Trade Organization. The repeal of the ETI would result in the elimination of this tax benefit thereby increasing the Company's future effective income tax rate, which could have a material adverse effect on the Company's operating results. Products Dependent on Certain Industries. Sales of the Company's products are dependent on customers in certain industries, particularly the telecommunications, semiconductor, automotive, automated test equipment, defense and aerospace industries. As experienced in the past, and as may be expected to occur in the future, downturns characterized by diminished product demand in any one or more of these industries could result in decreased sales, which could have a material adverse effect on the Company's operating results. Dependence on Key Suppliers. The Company's manufacturing processes use large volumes of high-quality components and subassemblies supplied by outside sources. Several of these components are available through sole or limited sources. Sole-source components purchased by the Company include custom application-specific integrated circuits ("ASICS") and other components. The Company has in the past experienced delays and quality problems in connection with sole-source components, and there can be no assurance that these problems will not recur in the future. Accordingly, the failure to receive sole-source components from suppliers could result in a material adverse effect on the Company's revenues and operating results. Stock-based Compensation Plans. The Company has two active stock-based compensation plans and one inactive plan. The two active stock-based compensation plans are the 1994 Incentive Stock Option Plan and the Employee Stock Purchase Plan. The Company currently adheres to the disclosure only provisions of SFAS No. 123 as amended by SFAS No. 148, Accounting for Stock-Based Compensation - Transition and Disclosure, and as such, no compensation cost has been recognized in the Company's financial statements for the stock option plan and the stock purchase plan. The Company is currently monitoring the recent discussions related to possible new regulations regarding the accounting treatment for stock options. The Company will comply with any changes in the accounting of stock options required by the FASB and the Securities and Exchange Commission. If the fair value based method of accounting for stock options established under SFAS No. 123 were adopted effective January 1, 2003 under the prospective method, the Company estimates it would have recognized stock option expense of approximately $880,000 in 2003. The impact of the adoption of the fair value based method of accounting for stock options established under SFAS No. 123 effective January 1, 2003 under the retroactive restatement method is reflected in Stock Based Compensation Plans in Note 1 of Notes to Consolidated Financial Statements. Provisions in Our Charter Documents and Delaware Law and Our Stockholder Rights Plan May Delay or Prevent an Acquisition of Us. Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire us without the consent of our Board of Directors. These provisions include a classified Board of Directors, prohibition of stockholder action by written consent, prohibition of stockholders to call special meetings and the requirement that the holders of at least 80% of our shares approve any business combination not otherwise approved by two-thirds of the Board of Directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. In addition, our Board of Directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer. Our Board of Directors adopted a new stockholders rights plan on January 21, 2004, pursuant to which we declared and will pay a dividend of one right for each share of our common stock outstanding as of May 10, 2004. This rights plan will replace a similar rights plan that has been in effect since our initial public offering in 1995. Unless redeemed by us prior to the time the rights are exercised, upon the occurrence of certain events, the rights will entitle the holders to receive upon exercise thereof shares of our preferred stock, or shares of an acquiring entity, having a value equal to twice the then-current exercise price of the right. The issuance of the rights could have the effect of delaying or preventing a change of control of us. Proprietary Rights and Intellectual Property Litigation. The Company's success depends on its ability to obtain and maintain patents and other proprietary rights relative to the technologies used in its principal products. Despite the Company's efforts to protect its proprietary rights, unauthorized parties may have in the past infringed or violated certain of the Company's intellectual property rights. The Company from time to time engages in litigation to protect its intellectual property rights. In monitoring and policing its intellectual property rights, the Company has been and may be required to spend significant resources. The Company from time to time may be notified that it is infringing certain patent or intellectual property rights of others. There can be no assurance that the SoftWIRE case and/or other existing litigation, and any other intellectual property litigation initiated in the future, will not cause significant litigation expense, liability, injunction against some of the Company's products, and a diversion of management's attention any of which may have a material adverse effect on the Company's operating results. Dependence on Key Management and Technical Personnel. The Company's success depends to a significant degree upon the continued contributions of its key management, sales, marketing, research and development and operational personnel, including Dr. Truchard, the Company's Chairman and Chief Executive Officer, and other members of senior management and key technical personnel. The Company has no agreements providing for the employment of any of its key employees for any fixed term and the Company's key employees may voluntarily terminate their employment with the Company at any time. The loss of the services of one or more of the Company's key employees in the future could have a material adverse affect on the Company's operating results. The Company also believes its future success will depend upon its ability to attract and retain additional highly skilled management, technical, marketing, research and development, and operational personnel with experience in managing large and rapidly changing companies, as well as training, motivating and supervising employees. In addition, the recruiting environment for software engineering, sales and other technical professionals is very competitive. Competition for qualified software engineers is particularly intense and is likely to result in increased personnel costs. Failure to attract or retain qualified software engineers could have an adverse effect on the Company's operating results. The Company also recruits and employs foreign nationals to achieve its hiring goals primarily for engineering and software positions. There can be no guarantee that the Company will continue to be able to recruit foreign nationals at the current rate. These factors further intensify competition for key personnel, and there can be no assurance that the Company will be successful in retaining its existing key personnel or attracting and retaining additional key personnel. Failure to attract and retain a sufficient number of the Company's key personnel could have a material adverse effect on the Company's operating results. Risk of Product Liability Claims. The Company's products are designed to provide information upon which the users may rely. The Company attempts to assure the quality and accuracy of the processes contained in its products, and to limit its product liability exposure through contractual limitations on liability, including disclaimers in its "shrink wrap" license agreements with end-users. If future products contain errors that produce incorrect results on which users rely, customer acceptance of the Company's products could be adversely affected. Further, the Company could be subject to liability claims that could have a material adverse effect on the Company's operating results or financial position. Although the Company maintains liability insurance, there can be no assurance that such insurance or the contractual provisions used by the Company to limit its liability will be sufficient. ITEM 7(a). MARKET RISK Response to this item is included in "Item 7--Management's Discussion and Analysis of Financial Condition and Results of Operations--Market Risk" above. ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA The information required by this item is incorporated by reference to the Consolidated Financial Statements set forth on pages F-1 through F-22 and S-1 hereof. ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE Not applicable. ITEM 9A.

NATIONAL INSTRUMENTS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1: Operations and summary of significant accounting policies National Instruments Corporation (the "Company") is a Delaware Corporation. The Company engages in the design, development, manufacture and marketing of instrumentation software and specialty computer plug-in cards and accessories that users combine with industry standard computers, networks and the Internet to create measurement and automation systems. The Company offers hundreds of products used to create virtual instrumentation systems for general, commercial, industrial and scientific applications. The Company's products may be used in different environments, and consequently, specific application of the Company's products is determined by the customer and often is not known to the Company. The Company approaches all markets with essentially the same products, which are 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 2003 presentation. Use of estimates Judgments and estimates by management are required in the preparation of financial statements to conform with U.S. 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 original 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. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The Company's 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 is replacement cost with respect to raw materials and, is net realizable value with respect to work in process and finished goods. Inventory is shown net of valuation allowance for excess and obsolete inventories of $3.8 million and $3.5 million at December 31, 2003 and 2002, 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, three to seven years for purchased internal use software 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. Technological feasibility for National Instruments products is established when the product is available for beta release. 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. Patents are amortized using the straight-line method over their estimated period of benefit, generally seventeen years. At each balance sheet date, the unamortized costs for all intangible assets 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. Beginning in 2002 with the adoption of SFAS No. 142, Goodwill and Other Intangible Assets, goodwill is no longer amortized, but instead tested for impairment at least annually. Prior to 2002, goodwill was amortized using the straight-line method over its estimated period of benefit, ten years. 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 largest trade account receivable from any individual customer at December 31, 2003 was approximately $628,000. Revenue recognition Sales revenue is generally 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, 2003 and 2002 was $8.1 million and $5.4 million, respectively. Accounts receivable are net of allowances for doubtful accounts and sales returns of $3.2 million and $3.8 million at December 31, 2003 and 2002, respectively. Warranty reserve The Company offers a one-year limited warranty on most hardware products and a 90-day warranty on software products, which is included in the sales price of many of its products. Provision is made for estimated future warranty costs at the time of sale. The warranty reserve at December 31, was as follows (in thousands): Dollar Amount of Liability -------------------------- 2003 2002 ---------- ---------- Balance at the beginning of the period.............. $ 715 $ 865 Accruals for warranties issued during the period.... 1,087 988 Settlements made (in cash or in kind) during the period............................................. (1,087) (1,138) ---------- ---------- Balance at the end of the period.................... $ 715 $ 715 ========== ========== Legal defense costs The Company accrues for probable losses from contingencies including 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. Advertising expense The Company expenses its costs of advertising as incurred. Advertising expense for the years ended December 31, 2003, 2002 and 2001 was $35.0 million, $29.6 million and $30.4 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 re-measuring 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 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. The Company does not enter into derivative contracts 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 of a hedged item (forecasted transactions); or (2) the derivative is de-designated as a hedge instrument, because it is unlikely that a forecasted transaction will occur. When hedge accounting is discontinued, the derivative is sold and the resulting gains and losses will be recognized immediately in 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. 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. Earnings per share Basic earnings per share ("EPS") is computed by dividing net income by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. Common share equivalents include stock options. The number of common share equivalents outstanding relating to stock options is computed using the treasury stock method. The reconciliation of the denominators used to calculate basic EPS and diluted EPS for the years ended December 31, 2003, 2002 and 2001, respectively, are as follows (in thousands): Years Ended December 31, 2003 2002 2001 -------- -------- -------- Weighted average shares outstanding-basic..... 51,625 51,219 50,910 Plus: Common share equivalents Stock options................................ 2,339 2,192 2,741 -------- -------- -------- Weighted average shares outstanding-diluted... 53,964 53,411 53,651 ======== ======== ======== Stock options to acquire 1,454,000, 1,649,000 and 1,394,000 shares for the years ended December 31, 2003, 2002 and 2001, respectively, were excluded from the computations of diluted earnings per share because the effect of including these stock options would have been anti-dilutive. Stock-based compensation plans The Company has two active stock-based compensation plans and one inactive plan. The two active stock-based compensation plans are the 1994 Incentive Stock Option Plan and the Employee Stock Purchase Plan. The Company follows the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based Compensation as amended by SFAS No.148, Accounting for Stock-Based Compensation - - Transition and Disclosure. As allowed by SFAS No. 123, the Company continues to apply the provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock issued to Employees, and related interpretations in accounting for its plans. Accordingly, compensation cost for stock options is measured as the excess, if any, of the quoted market price of the Company's stock at the date of the grant over the amount an employee must pay to acquire the stock. No compensation cost has been recognized in the Company's financial statements for the stock option plan and the stock purchase plan. If compensation cost for the Company's two active stock-based compensation plans were determined based on the fair value at the grant date for awards under those plans consistent with the method established by SFAS No. 123, the Company's net income and earnings per share would approximate the pro-forma amounts below (in thousands, except per share data): Years Ended December 31, ---------------------------------- 2003 2002 2001 ---------- ---------- ---------- Net income, as reported..................... $ 33,368 $ 31,405 $ 36,402 Stock-based compensation included in reported net income, net of related tax effects............................... -- -- -- Total stock-based compensation expense determined under fair value method for all awards, net of related tax effects....

The Company's other comprehensive income is from foreign currency translation and unrealized gains and losses on forward and option contracts and securities available for sale. Total comprehensive income for 2003, 2002 and 2001 was $34.9 million, $26.5 million and $36.4 million, respectively. Recently issued accounting pronouncement In May 2003, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity. This Statement establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances) because that financial instrument embodies an obligation of the issuer. This Statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. It is to be implemented by reporting the cumulative effect of a change in an accounting principle for financial instruments created before the issuance date of the Statement and still existing at the beginning of the interim period of adoption. The adoption of SFAS No. 150 did not have a material effect on the Company's financial position or results of operations. Note 2: Short-term investments Short-term investments at December 31, 2003 and 2002, consisting of corporate, state and municipal securities, were acquired at an aggregate cost of $141.2 million and $113.6 million, respectively.

Note 5: Intangibles and other assets Intangibles and other assets, net of accumulated amortization at December 31, 2003 and 2002 are as follows: December 31, 2003 2002 ---------- ---------- Capitalized software development costs and acquired technology............................... $ 17,234 $ 9,312 Goodwill............................................ 10,280 5,795 Patents............................................. 5,978 5,636 Investment.......................................... 2,500 2,500 Long-term deferred tax asset........................ 2,123 2,109 Deposits and other.................................. 4,299 3,263 ---------- ---------- $ 42,414 $ 28,615 At December 31, 2003 and 2002, accumulated amortization on capitalized software development costs and acquired technology was $22.1 million and $15.6 million, respectively, accumulated amortization on goodwill was $2.3 million and $1.9 million, respectively, and accumulated amortization on patents was $1.5 million and $1.1 million, respectively. Total amortization costs were $6.2 million, $4.7 million and $4.2 million for the years ended December 31, 2003, 2002 and 2001, respectively. Software development costs capitalized during 2003, 2002 and 2001 were $10.7 million, $5.8 million and $3.9 million, respectively, and related amortization was $5.6 million, $3.8 million and $3.1 million, respectively. In 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. The Company adopted SFAS No. 142 effective January 1, 2002. Adoption of SFAS No. 142 did not have a material impact on the Company's financial position or results of operations.

The Company's tax valuation allowance relates to the realizability of certain of these foreign net operating loss carryforwards. As a result of certain foreign investment incentives available under Hungarian law, the profit from the Company's Hungarian operation is currently exempt from income tax. The Company has not provided for U.S. federal income and foreign withholding taxes on approximately $17.4 million of certain non-U.S. subsidiaries' undistributed earnings as of December 31, 2003. These earnings would become subject to taxes of approximately $5.0 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: Stockholders' equity 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 935,150 shares for approximately $23.1 million. 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, 2003 were 1,606,326. Transactions under all plans are summarized as follows: Weighted Number of average shares under exercise option price ------------ -------- Outstanding at December 31, 2000.................... 6,314,514 $ 22.40 Exercised.......................................

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 1,471,518 shares at December 31, 2003. Shares issued under this plan were 353,810 in 2003. The weighted average fair value of the employees' purchase rights, as shown below was estimated using the Black-Scholes model with the following assumptions: 2003 2002 2001 ---------- ---------- ---------- Dividend expense yield................ 0.1% 0% 0% Expected life......................... 6 months 6 months 6 months Expected volatility................... 33% 49% 63% Risk-free interest rate............... 1.1% 2.3% 5.1% Weighted average, grant date fair value of purchase rights granted under the Employee Stock Purchase Plan: Weighted Number average of shares fair value --------- ---------- 2001....................................... 290,082 $ 9.62 2002....................................... 323,265 8.22 2003....................................... 259,909 9.20 Authorized Preferred Stock and Preferred Stock Purchase Rights Plan National Instruments has 5,000,000 authorized shares of preferred stock. On January 21, 2004, the Board of Directors of National Instruments designated 500,000 of these shares as Series A Participating Preferred Stock in conjunction with its adoption of a Preferred Stock Rights Agreement (the "Rights Agreement") and declaration of a dividend of one preferred share purchase right (a "Right") for each share of common stock outstanding held as of May 10, 2004 or issued thereafter. Each Right will entitle its holder to purchase one one-thousandth of a share of National Instruments' Series A Participating Preferred Stock at an exercise price of $200 (after giving effect to the 3 for 2 stock split in the form of a stock dividend declared by the Board of Directors of the Company on January 21, 2004), subject to adjustment, under certain circumstances. The Rights Agreement was not adopted in response to any effort to acquire control of National Instruments. The Rights only become exercisable in certain limited circumstances following the tenth day after a person or group announces acquisitions of or tender offers for 20% or more of National Instruments' common stock. In addition, if an acquirer (subject to certain exclusions for certain current stockholders of National Instruments, an "Acquiring Person") obtains 20% or more of National Instruments' common stock, then each Right (other than the Rights owned by an Acquiring Person or its affiliates) will entitle the holder to purchase, for the exercise price, shares of National Instruments' common stock having a value equal to two times the exercise price. Under certain circumstances, the National Instruments' Board of Directors may redeem the Rights, in whole, but not in part, at a purchase price of $0.01 per Right. The Rights have no voting privileges and are attached to and automatically traded with National Instruments common stock until the occurrence of specified trigger events. The Rights will expire on the earlier of May 10, 2014 or the exchange or redemption of the Rights. Note 8: 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 thirty days 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. Employees are eligible for the Company's matching contributions after one year of continuous service. 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 $2.0 million, $1.8 million and $1.6 million in 2003, 2002 and 2001, respectively. Note 9: 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. 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, 2003 and 2002 are as follows (in thousands): December 31, 2003 2002 -------------------- -------------------- Carrying Fair Carrying Fair Amount Value Amount Value --------- --------- --------- --------- Short-term investments............... $141,227 $141,227 $113,638 $113,638 Other assets/liabilities: Forward contracts................ (5,552) (5,552) (2,685) (2,685) Purchased options................ (35) (35) 694 694 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 10: Derivative instruments and hedging activities The Company has operations in 40 countries. Approximately 53% 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 and cash flow of the Company, 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. The Company held forward contracts with notional amounts totaling $27.7 million and $24.1 million at December 31, 2003 and 2002, respectively, that were designated as foreign currency fair value hedges of the Company's foreign denominated receivables. The fair value of these contracts, which are for 90-day periods, is a liability of $1.6 million at December 31, 2003, and a liability of $1.3 million at December 31, 2002. The Company recorded a net loss of $4.6 million and $4.9 million for fair value hedges for the years ended December 31, 2003 and 2002, respectively, and 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. The Company held forward contracts with a notional amount of $48.6 million and $48.1 million and option contracts with notional amounts totaling $42.4 million and $86.4 million at December 31, 2003 and 2002, respectively, that were designated as foreign currency cash flow hedges related to the Company's anticipated sales transactions. The fair value of these contracts, which are for terms up to twenty-four months, is a liability of $4.0 million and $2.8 million at December 31, 2003 and 2002, respectively, and a net unrealized deferred loss of $4.0 million and $2.8 million at December 31, 2003 and 2002, respectively, 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 loss of $6.9 million and net gains of $3.6 million and $4.4 million for cash flow hedges for the year ended December 31, 2003, 2002 and 2001, respectively, which was included in "Net Revenue." As of December 31, 2003, $3.4 million of deferred losses 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 losses. 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. No amounts were excluded from the assessment of hedge effectiveness for the years ended December 31, 2003 and 2002. Note 11: 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 markets, its management has chosen to organize the Company by geographic areas, and as a result has determined that it has one reportable segment. Substantially all of the interest income, interest expense, depreciation and amortization is recorded in North America.

Note 12: Commitments, contingencies and leases The Company has commitments under non-cancelable operating leases primarily for office facilities and equipment. Future minimum lease payments as of December 31, 2003, for each of the next five years are as follows (in thousands): 2004................................ $ 7,113 2005................................ 5,387 2006................................ 3,202 2007................................ 2,089 2008................................ 881 Thereafter.......................... 6,014 ------- $24,686 During 2002, the Company and Trilogy Software ("Trilogy") settled a dispute regarding Trilogy's buy-out of the lease of the Company's Millenium office building which resulted in a gain of approximately $6.0 million from lease termination. As a result of additional facility lease consolidation, the Company incurred lease termination costs of approximately $2.4 million in 2002. These amounts were included in general and administrative expenses. Rent expense under operating leases was approximately $6.3 million, $6.3 million and $5.4 million for the years ended December 31, 2003, 2002 and 2001, respectively. As of December 31, 2003, the Company has non-cancelable purchase commitments with various suppliers of customized inventory and inventory components totaling approximately $3.4 million over the next twelve months. As of December 31, 2003, the Company has outstanding guarantees for payment of foreign operating leases, customs and foreign grants totaling approximately $3.5 million. Note 13: Litigation The Company has filed two complaints against The MathWorks, Inc. ("Defendant") for patent infringement. In both complaints, the Company claimed the Defendant infringes certain of its U.S. patents and the Defendant challenged the validity and enforceability of those patents and asserts that it does not infringe the claims of those patents. The first complaint was filed on January 25, 2001 in the U.S. District Court, Eastern District of Texas (Marshall Division). On January 30, 2003, the jury found infringement by the Defendant of three of the patents involved and awarded the Company specified damages. On June 23, 2003, the Court entered final judgement in favor of the Company in an amount of approximately $4 million and entered an injunction against Defendant's sale of its Simulink and related products. The Court stayed the injunction pending appeal of the case and required the Defendant to pay a specified royalty on its U.S. sales of the same products during the pendency of appeal. The initial judgement and the royalties on the sales of infringing products through December 31, 2003 total $4.9 million and are escrowed. On July 22, 2003, Defendant filed its Notice of Appeal and the case is currently pending on appeal before the U.S. Court of Appeals for the Federal Circuit. The final judgement has not been recorded in the financial statements of the Company pending the disposition of the appeal. The second complaint was filed October 21, 2002, also in the U.S. District Court, Eastern District of Texas (Marshall Division) and on August 27, 2003, the complaint was dismissed by agreement of the parties. On January 15, 2003, SoftWIRE Technology, LLC ("SoftWIRE") and Measurement Computing Corporation ("MCC") filed a complaint against the Company in the U.S. District Court for the District of Massachusetts asking the court to declare that SoftWIRE does not infringe certain of the Company's U.S. patents and that such patents are invalid and unenforceable. On February 21, 2003, the Company filed a complaint against SoftWIRE and MCC in the U.S. District Court, Eastern District of Texas (Marshall Division) claiming that both SoftWIRE and MCC infringe the same and certain other of the Company's U.S. patents. SoftWIRE and MCC challenge the validity and enforceability of these patents and assert that they do not infringe any of these patents. In the Eastern District action, the Company seeks monetary damages and injunction of the sale of certain products of SoftWIRE and MCC as well as attorney's fees and costs. By order of the Court, the Eastern District action was transferred to the U.S. District Court for the District of Massachusetts on May 9, 2003, and has been consolidated with the previously-filed SoftWIRE action, which also includes counterclaims by the Company that are the same in substance as the Company's claims in the Eastern District action. On June 12, 2003, SoftWIRE moved for leave to amend its complaint in order to allege that the Company infringes two U.S. patents that SoftWIRE acquired by purchase on May 23, 2003. On November 5, 2003, the Court granted SoftWIRE's motion to amend, thereby adding SoftWIRE's two patents to the litigation. With respect to those two SoftWIRE patents, SoftWIRE seeks monetary damages and injunction of the sale of certain products of the Company as well as attorney's fees and costs. The Company challenges the validity, enforceability and alleged infringement of those patents and intends to vigorously defend against SoftWIRE's claims. Discovery in the litigation is underway. During the fourth quarter of 2003, the Company accrued $3.8 million related to its probable loss from this contingency, which consists solely of anticipated patent defense costs that are probable of being incurred. However, the outcome of any litigation is inherently uncertain and there can be no assurance as to the ultimate outcome of this matter or any other litigation. The Company did not make any charges against this accrual during calendar 2003. Note 14: Related party transactions During 2002, the Company contributed approximately $3.6 million to the National Instruments Foundation, a 501(c)(3) charitable foundation established in 2002 for the purpose of continued promotion of scientific and engineering research and education at higher education institutions worldwide. This contribution was recorded as general and administrative expense in 2002. Two of the four directors of the National Instruments Foundation are current officers of National Instruments.

The Company's Board of Directors declared on January 21, 2004, 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 is payable on or about February 20, 2004 to holders of record as of the close of business on February 5, 2004.

     1. Provisions Relating to the Preferred Stock.

          (a) The Preferred Stock may be issued from time to time in one or more
     classes  or  series,  the  shares  of each  class or  series  to have  such
     designations  and  powers,  preferences,  and rights,  and  qualifications,
     limitations,  and restrictions  thereof, as are stated and expressed herein
     and in the resolution or resolutions  providing for the issue of such class
     or series adopted by the board of directors of the Corporation as hereafter
     prescribed.

          (b) Authority is hereby  expressly  granted to and vested in the board
     of directors of the  Corporation to authorize the issuance of the Preferred
     Stock from time to time in one or more classes or series,  and with respect
     to each  class or series of the  Preferred  Stock,  to fix and state by the
     resolution  or  resolutions  from time to time  adopted  providing  for the
     issuance thereof the following:

               i.  whether or not the class or series is to have voting  rights,
          full,  special,  or limited,  or is to be without voting  rights,  and
          whether  or not such  class or series is to be  entitled  to vote as a
          separate  class  either  alone or together  with the holders of one or
          more other classes or series of stock;

               ii.  the number of shares to  constitute  the class or series and
          the designations thereof;

               iv.  whether  or not the  shares of any class or series  shall be
          redeemable at the option of the  Corporation or the holders thereof or
          upon the happening of any specified  event,  and, if  redeemable,  the
          redemption  price or prices (which may be payable in the form of cash,
          notes, securities, or other property), and the time or times at which,
          the terms and conditions  upon which,  such shares shall be redeemable
          and the manner of redemption;

               v.  whether  or not the  shares  of a class  or  series  shall be
          subject to the  operation of retirement or sinking funds to be applied
          to the purchase or redemption of such shares for  retirement,  and, if
          such  retirement or sinking fund or funds are to be  established,  the
          annual amount  thereof,  and the terms and provisions  relative to the
          operation thereof;

               vi. the dividend  rate,  whether  dividends  are payable in cash,
          stock of the Corporation, or other property, the conditions upon which
          and the times when such  dividends are payable,  the  preference to or
          the relation to the payment of dividends payable on any other class or
          classes  or series of stock,  whether or not such  dividends  shall be
          cumulative or noncumulative, and if cumulative, the date or dates from
          which such dividends shall accumulate;

               vii. the  preferences,  if any, and the amounts thereof which the

          distribution of the assets of, the Corporation;

               viii.  whether or not the  shares of any class or series,  at the
          option of the  Corporation or the holder thereof or upon the happening
          of any specified event, shall be convertible into or exchangeable for,
          the shares of any other class or classes or of any other series of the
          same or any other  class or  classes  of stock,  securities,  or other
          property  of the  Corporation  and the  conversion  price or prices or
          ratio or ratios  or the rate or rates at which  such  exchange  may be

          or provided for in such resolution or resolutions; and

               ix. such other  special  rights and  protective  provisions  with
          respect to any class or series as may to the board of directors of the
          Corporation seem advisable.

          (c) The shares of each class or series of the Preferred Stock may vary
     from the shares of any other  class or series  thereof in any or all of the
     foregoing respects.  The board of directors of the Corporation may increase
     the number of shares of the  Preferred  Stock  designated  for any existing
     class or series by a resolution  adding to such class or series  authorized
     and unissued  shares of the Preferred  Stock not  designated  for any other
     class or series. The board of directors of the Corporation may decrease the
     number of shares of the Preferred  Stock  designated for any existing class
     or series by a resolution  subtracting from such class or series authorized
     and unissued  shares of the Preferred  Stock  designated  for such existing
     class or series,  and the shares so  subtracted  shall  become  authorized,
     unissued, and undesignated shares of the Preferred Stock.

     2. Provisions Relating to the Common Stock.

          (a) Each share of Common Stock of the Corporation shall have identical
     rights and  privileges  in every  respect.  The holders of shares of Common
     Stock shall be entitled to vote upon all manners submitted to a vote of the
     stockholders  of the Corporation and shall be entitled to one vote for each
     share of Common Stock held.

          (b) Subject to the prior rights and preferences, if any, applicable to
     shares of the Preferred Stock or any series thereof,  the holders of shares
     of the Common Stock shall be entitled to receive such dividends (payable in
     cash,  stock,  or  otherwise)  as may be  declared  thereon by the board of
     directors  at any  time  and  from  time to time  out of any  funds  of the
     Corporation legally available therefor.

          (c)  In  the  event  of  any  voluntary  or  involuntary  liquidation,
     dissolution,  or winding-up of the Corporation,  after distribution in full
     of the  preferential  amounts,  if any, to be distributed to the holders of
     shares of the Preferred Stock or any series thereof,  the holders of shares
     of the Common  Stock  shall be  entitled  to receive  all of the  remaining
     assets of the Corporation  available for distribution to its  stockholders,
     ratably in  proportion  to the number of shares of the Common Stock held by
     them. A liquidation, dissolution, or winding-up of the Corporation, as such
     terms are used in this  paragraph (c), shall not be deemed to be occasioned
     by or to include any  consolidation  or merger of the  Corporation  with or
     into any  other  corporation  or  corporations  or other  entity or a sale,
     lease,  exchange,  or  conveyance  of all or a part  of the  assets  of the
     Corporation.

     3. General.

          (a)  Subject  to the  foregoing  provisions  of  this  Certificate  of
     Incorporation,  the Corporation may issue shares of its Preferred Stock and
     Common  Stock from time to time for such  consideration  (not less than the
     par  value  thereof)  as may be fixed  by the  board  of  directors  of the
     Corporation,  which is expressly authorized to fix the same in its absolute
     and uncontrolled discretion subject to the foregoing conditions.  Shares so
     issued for which the consideration shall have been paid or delivered to the
     Corporation shall be deemed fully paid stock and shall not be liable to any
     further call or  assessment  thereon,  and the holders of such shares shall
     not be liable for any further payments in respect of such shares.

          (b) The  Corporation  shall have  authority to create and issue rights
     and options entitling their holders to purchase shares of the Corporation's
     capital  stock  of  any  class  or  series  or  other   securities  of  the
     Corporation,   and  such  rights  and  options   shall  be   evidenced   by
     instrument(s)  approved by the board of directors of the  Corporation.  The
     board  of  directors  of the  Corporation  shall  be  empowered  to set the
     exercise  price,  duration,  times for  exercise,  and other  terms of such
     options or rights; provided, however, that the consideration to be received
     for any shares of capital stock subject  thereto shall not be less that the
     par value thereof.

     FIFTH:  The name of the  incorporator of the Corporation is Susan E. Casey,
and the mailing address of such incorporator is 100 Congress Avenue, Suite 1400,
Austin, Texas 78701.

     SIXTH: (a) General. The number of directors  constituting the initial board
of directors is eight, and the name and mailing address of each person who is to
serve as director  until his or her successor is elected and qualified are Class
I: Gerald T. Olson and Jim A. Smith; Class II: William C. Nowlin,  Jr., L. Wayne
Ashby and Dr. Donald M. Carlton;  Class III: Dr. James J.  Truchard,  Jeffrey L.
Kodosky and Dr. Peter T. Flawn. The number of directors  constituting the entire
Board of  Directors  shall be not less than three nor more than  twelve as fixed
from time to time by vote of a majority of the entire Board; provided,  however,
that the number or  directors  shall not be reduced so as to shorten the term of
any director at the time in office. Election of directors need not be by written
ballot unless the bylaws of the Corporation so provide.

     (b) Classification of Directors.  The directors shall be divided into three
classes of equal or approximately  equal number and designated Class I, Class II
and Class III. If the number of directors is not evenly  divisible by three, the
remainder  positions  shall be allocated  first to Class III and second to Class
II. The initial  term of office of Class I will expire at the annual  meeting of
stockholders in 1995; of Class II at the annual meeting of stockholders in 1996;
and of Class III at the annual meeting of  stockholders  in 1997.  Each director
elected  shall  hold  office  until his  successor  shall be  elected  and shall
qualify.  At each  annual  meeting  of  stockholders  beginning  with the annual
meeting of stockholders in 1995,  directors elected to succeed those whose terms
are then  expiring  shall be elected  for a full term of office  expiring at the
third succeeding annual meeting of stockholders after their election. Should the
number of directors which constitutes the whole Board of Directors be changed as
permitted by paragraph (a) of this Article,  such majority of the whole Board of
Directors  shall also fix and  determine  the number of  directors of which each
class shall be comprised.

     (c) Term of Office;  Vacancies.  A director  shall  hold  office  until the
annual  meeting  for the year in which his or her term  expires and until his or
her successor  shall be elected and shall qualify,  subject,  however,  to prior
death,  resignation,  retirement  or removal from office.  Except as provided in
paragraph (b) of this Article,  the directors  have the exclusive  power to fill
vacancies and newly  created  directorships  resulting  from any increase in the
authorized number of directors. Any newly created directorship resulting from an
increase  in the  number  of  directors  or any  other  vacancy  on the Board of
Directors,  however caused,  shall be filled by a majority of the directors then
in office,  although less than a quorum,  or by a sole remaining  director.  Any
director  elected by one or more directors to fill a newly created  directorship
or other  vacancy  shall hold  office  until the next  election of the class for
which such directors shall have been chosen and until his or her successor shall
have been elected and qualified.  Notwithstanding  the foregoing,  and except as
otherwise  required  by law,  whenever  the holders of any one or more series of
Preferred Stock shall have the right, voting separately as a class, to elect one
or more  directors  of the  Corporation,  the terms of the director or directors
elected by such holders shall expire at the next  succeeding  annual  meeting of
stockholders.

     (d) Removal.  Notwithstanding  any other  provisions of this Certificate of
Incorporation  or the bylaws of the Corporation  (and  notwithstanding  the fact
that some  lesser  percentage  may be  specified  by law,  this  Certificate  of
Incorporation  or the bylaws of the  Corporation),  any  director  or the entire
Board of Directors of the  Corporation  may be removed at any time, but only for
cause and only by the  affirmative  vote of the  holders  of at least 80% of the
votes of the  outstanding  shares  of stock  generally  entitled  to vote in the
election  of  directors  (considered  for this  purpose as one  class)  ("Voting
Stock") cast at a meeting of stockholders called for that purpose.

     (e) Notice of  Nominations.  Advance notice of nominations for the election
of directors,  other than  nominations  by the Board of Directors or a committee
thereof, shall be given to the Corporation in the manner provided in the bylaws.

     (f)  Election of Directors  by Holders of  Particular  Classes or Series of
Stock.  Notwithstanding  the foregoing,  whenever the holders of any one or more
classes  or series of stock  issued by the  Corporation  shall  have the  right,
voting separately by class or series, to elect directors at an annual or special
meeting of stockholders,  the election, term of office, filling of vacancies and
other features of such directorships shall be governed by the provisions of this
Certificate of Incorporation,  including any applicable resolutions of the Board
of Directors, adopted pursuant to Article FOURTH. Directors so elected shall not
be divided  into classes and shall be elected by such  holders  annually  unless
expressly provided otherwise by those provisions or resolutions, and, during the
prescribed  terms of office of those  directors,  the Board of  Directors  shall
consist of a number of directors equal to the number of those directors plus the
number of  directors  determined  as  provided  in the first  paragraph  of this
Article.

     SEVENTH:  A director of the Corporation  shall not be personally  liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director,  except for liability  (i) for any breach of the  director's
duty of  loyalty  to the  Corporation  or its  stockholders,  (ii)  for  acts or
omissions not in good faith or which involve  intentional  misconduct or knowing
violation of law,  (iii) under Section 174 of the Delaware  General  Corporation
Law, or (iv) for any  transaction  from which the  director  derived an improper
personal benefit. Any repeal or amendment of this Article by the stockholders of
the Corporation  shall be prospective  only, and shall not adversely  affect any
limitation on the personal  liability of a director of the  Corporation  arising
from an act or omission occurring prior to the time of such repeal or amendment.
In addition to the  circumstances  in which a director of the Corporation is not
personally  liable as set forth in the foregoing  provisions of this Article,  a
director  shall not be liable to the  Corporation  or its  stockholders  to such
further  extent as permitted by any law  hereafter  enacted,  including  without
limitation any subsequent amendment to the Delaware General Corporation Law.

     EIGHTH:  The  Corporation  shall  indemnify  any person who was,  is, or is
threatened to be made a party to a proceeding (as hereinafter defined) by reason
of the fact he or she (i) is or was a director or officer of the  Corporation or
(ii) while a director  or officer of the  Corporation,  is or was serving at the
request  of  the  Corporation  as  a  director,   officer,  partner,   venturer,
proprietor,  trustee, employee, agent, or similar functionary of another foreign
or domestic corporation, partnership, joint venture, sole proprietorship, trust,
employee  benefit plan, or other  enterprise,  to the fullest  extent  permitted
under the Delaware General  Corporation Law, as the same exists or may hereafter
be amended.  Such right  shall be a contract  right and as such shall run to the
benefit of any  director or officer  who is elected and accepts the  position of
director  or  officer of the  Corporation  or elects to  continue  to serve as a
director  or officer of the  Corporation  while this  Article is in effect.  Any
repeal or  amendment  of this Article  shall be  prospective  only and shall not
limit the  rights of any such  director  or officer  or the  obligations  of the
Corporation with respect to any claim arising from or related to the services of
such  director or officer in any of the foregoing  capacities  prior to any such
repeal or amendment to this  Article.  Such right shall  include the right to be
paid by the  Corporation  expenses  incurred in defending any such proceeding in
advance of its final  disposition  to the  maximum  extent  permitted  under the
Delaware  General  Corporation  Law,  as the same  exists  or may  hereafter  be
amended.  If a claim for indemnification or advancement of expenses hereunder is
not paid in full by the Corporation within sixty (60) days after a written claim
has been received by the  Corporation,  the claimant may at any time  thereafter
bring suit against the  Corporation  to recover the unpaid  amount of the claim,
and if successful in whole or in part, the claimant shall also be entitled to be
paid the expenses of prosecuting  such claim.  It shall be a defense to any such
action  that such  indemnification  or  advancement  of costs of defense are not
permitted under the Delaware General  Corporation Law, but the burden of proving
such defense shall be on the Corporation. Neither the failure of the Corporation
(including its board of directors or any committee  thereof,  independent  legal
counsel,   or  stockholders)  to  have  made  its  determination  prior  to  the
commencement of such action that  indemnification of, or advancement of costs of
defense  to, the  claimant is  permissible  in the  circumstances  nor an actual
determination  by the  Corporation  (including  its  board of  directors  or any
committee  thereof,  independent  legal  counsel,  or  stockholders)  that  such
indemnification  or  advancement  is not  permissible  shall be a defense to the
action or create a presumption that such  indemnification  or advancement is not
permissible.  In the  event  of the  death  of any  person  having  a  right  of
indemnification  under the foregoing  provisions,  such right shall inure to the
benefit  of  his  or  her  heirs,   executors,   administrators,   and  personal
representatives.  The rights conferred above shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute,  by-law,
resolution of stockholders or directors, agreement, or otherwise.

     The  Corporation  may  additionally  indemnify any employee or agent of the
Corporation to the fullest extent permitted by law.

     As used herein,  the term "proceeding"  means any threatened,  pending,  or
completed action, suit, or proceeding, whether civil, criminal,  administrative,
arbitrative,  or  investigative,   any  appeal  in  such  an  action,  suit,  or
proceeding,  and any inquiry or investigation that could lead to such an action,
suit, or proceeding.

     NINTH:  After the  Corporation  first has a class of securities  registered
under Sections 12 or 15 of the Securities  Exchange Act of 1934, as amended,  or
its equivalent, any action required or permitted to be taken by the stockholders
of the  Corporation  must be taken at a duly called annual or special meeting of
the stockholders and may not be taken by consent in writing or otherwise.

     TENTH: Except as otherwise required by law or provided in the bylaws of the
Corporation,  and subject to the rights of the holders of any class or series of
shares issued by the Corporation having a preference over the Common Stock as to
dividends  or upon  liquidation  to elect  directors  in certain  circumstances,
special  meetings of the  stockholders  of the Corporation may be called only by
the Board of Directors pursuant to a resolution approved by the affirmative vote
of a majority of the directors then in office.

     ELEVENTH:  The Board of  Directors  shall  have the power to adopt,  alter,
amend or  repeal  the  Bylaws  of the  Corporation  by vote of not  less  than a
majority of the directors then in office. The holders of shares of capital stock
of the  Corporation  entitled at the time to vote for the  election of directors
shall,  to the extent such power is at the time  conferred on them by applicable
law,  also have the power to adopt,  alter,  amend or repeal  the  bylaws of the
Corporation,  but only if such action receives the affirmative  vote of at least
80% of the outstanding Voting Stock, voting together as a single class.

     TWELFTH:  (a) 1. In addition to any  affirmative  vote required by law, and
except as otherwise  expressly provided in sections (b) and (c) of this Article,
any business  combination (as hereinafter defined) shall require the affirmative
vote of the  holders  of at least 80% of the  outstanding  Voting  Stock  voting
together  as  a  single  class.   Such   affirmative   vote  shall  be  required
notwithstanding  the fact  that no vote may be  required,  or that  some  lesser
percentage  may be  specified,  by law or in any  agreement  with  any  national
securities exchange or otherwise.

               2. The term "business  combination" as used in this Article shall
          mean any  transaction  which is  referred to in any one or more of the
          following clauses (A) through (E):

                    a. any merger or  consolidation  of the  Corporation  or any
               Subsidiary  (as  hereinafter   defined)  with  or  into  (i)  any
               Interested Stockholder (as hereinafter defined) or (ii) any other
               corporation  (whether  or not itself an  Interested  Stockholder)
               which, after such merger or consolidation,  would be an Affiliate
               (as hereinafter defined) of an Interested Stockholder, or

                    b. any sale, lease, exchange,  mortgage, pledge, transfer or
               other  disposition  (in one  transaction  or a series of  related
               transactions)  to or  with  any  Interested  Stockholders  of any
               assets of the  Corporation or any Subsidiary  having an aggregate
               fair market value of $5,000,000 or more, or

                    c.  the  issuance  or  transfer  by the  Corporation  or any
               Subsidiary   (in  one   transaction   or  a  series  of   related
               transactions)  of  any  securities  of  the  Corporation  or  any
               Subsidiary to any Interested  Stockholder or any Affiliate of any
               Interested  Stockholder in exchange for cash, securities or other
               property (or a  combination  thereof)  having an  aggregate  fair
               market value of $5,000,000 or more, or

                    d. the adoption of any plan or proposal for the  liquidation
               or dissolution of the Corporation, or

                    e. any reclassification of securities (including any reverse
               stock split),  or  recapitalization  of the  Corporation,  or any
               merger  or  consolidation  of  the  Corporation  with  any of its
               Subsidiaries or any similar  transaction  (whether or not with or
               into or otherwise involving an Interested  Stockholder) which has
               the  effect,   directly  or   indirectly,   of   increasing   the
               proportionate  share of the  outstanding  shares  of any class of
               equity  or  convertible  securities  of  the  Corporation  or any
               Subsidiary   which  is  directly  or  indirectly   owned  by  any
               Interested   Stockholder  or  any  Affiliate  of  any  Interested
               Stockholder.

     (b) The  provisions  of section (a) of this Article shall not be applicable
to any particular  business  combination,  and such business  combination  shall
require only such affirmative vote as is required by law and any other provision
of this  Certificate  of  Incorporation,  if the business  combination  has been
approved by two-thirds of the whole Board of Directors.

     (c) For the purposes of this Article:

          1. A "person" shall mean any  individual,  firm,  corporation or other
     entity.

          2.  "Interested  Stockholder"  shall mean,  in respect of any business
     combination,  any person (other than the Corporation or any Subsidiary) who
     or which,  as of the  record  date for the  determination  of  stockholders
     entitled  to  notice  of and to  vote  on  such  business  combination,  or
     immediately prior to the consummation of any such transaction;

               a. is the beneficial owner, directly or indirectly,  of more than
          10% of the Voting Stock, or

               b. is an Affiliate of the  Corporation and at any time within two
          years prior thereto was the beneficial owner,  directly or indirectly,
          of not less than 10% of the then outstanding Voting Stock, or

               c. is an assignee of or has otherwise  succeeded to any shares of
          capital  stock of the  Corporation  which were at any time  within two
          years prior thereto beneficially owned by any Interested  Stockholder,
          and such assignment or succession shall have occurred in the course of
          stockholders entitled to notice of and to vote on such business coming
          within the meaning of the Securities Act of 1933.

          3. A "person" shall be the "beneficial owner" of any Voting Stock:

               a. which such person or any of its  Affiliates and Associates (as
          hereinafter defined) beneficially own, directly or indirectly, or

               b. which such person or any of its  Affiliates or Associates  has
          (i)  the  right  to  acquire   (whether  such  right  is   exercisable
          immediately  or only  after  the  passage  of time),  pursuant  to any
          agreement,  arrangement  or  understanding  or upon  the  exercise  of
          conversion rights, exchange rights, warrants or options, or otherwise,
          or (ii) the right to vote pursuant to any  agreement,  arrangement  or
          understanding, or

               c. which are beneficially owned,  directly or indirectly,  by any
          other  person  with which such  first  mentioned  person or any of its
          Affiliates   or  Associates   has  any   agreement,   arrangement   or
          understanding  for the  purposes  of  acquiring,  holding,  voting  or
          disposing of any shares of capital stock of the Corporation.

          4. The  outstanding  Voting Stock shall  include  shares  deemed owned
     through  application  of  paragraph 3 above but shall not include any other
     Voting  Stock which may be  issuable  pursuant  to any  agreement,  or upon
     exercise of conversion rights, warrants or options, or otherwise.

          5.  "Affiliate"  and  "Associate"  shall have the respective  meanings
     given those terms in Rule 12b-2 of the General Rules and Regulations  under
     the  Securities  Exchange Act of 1934, as in effect on the date of adoption
     of this Article.

          6. "Subsidiary"  shall mean any corporation of which a majority of any
     class of equity  security  (as defined in Rule 3a11-1 of the General  Rules
     and Regulations under the Securities  Exchange Act of 1934, as in effect on
     the date of the adoption of this Article) is owned, directly or indirectly,
     by  the  Corporation;  provided  however,  that  for  the  purposes  of the
     definition  of  Interested  Stockholder  set forth in  paragraph  2 of this
     section (c) the term "Subsidiary"  shall mean only a corporation of which a
     majority of each class of equity security is owned, directly or indirectly,
     by the Corporation.

               (d) A majority of the directors  shall have the power and duty to
          determine for the purposes of this Article on the basis of information
          known to them,  (1) the number of shares of Voting Stock  beneficially
          owned by any person, (2) whether a person is an Affiliate or Associate
          of another,  (3)  whether a person has an  agreement,  arrangement  or
          understanding  with another as to the matters referred to in paragraph
          3 of section  (d), or (4) whether the assets  subject to any  business
          combination or the consideration received for the issuance or transfer
          of securities by the  Corporation  or any  Subsidiary has an aggregate
          fair market value of $5,000,000 or more.

               (e) Nothing  contained  in this  Article  shall be  construed  to
          relieve  any  Interested  Stockholder  from any  fiduciary  obligation
          imposed by law.


     THIRTEENTH:  No holder of shares of the  Corporation of any class or series
shall have any  preemptive  right to  subscribe  for,  purchase,  or receive any
shares of the Corporation of any class or series now or hereafter authorized, or
any options or warrants for such shares,  or any securities  convertible into or
exchangeable for such shares,  which may at any time be issued,  sold or offered
for  sale by the  Corporation.  Cumulative  voting  by the  stockholders  of the
Corporation  at  any  election  of  directors  of  the   Corporation  is  hereby
prohibited.

     FOURTEENTH: Notwithstanding anything to the contrary in this Certificate of
Incorporation,  the affirmative vote of the holders of at least 80% of the votes
of the outstanding  Voting Stock,  voting  together as a single class,  shall be
required  to  amend,  repeal  or adopt any  provision  inconsistent  with any of
Articles SIXTH, NINTH, TENTH,  ELEVENTH,  TWELFTH,  THIRTEENTH and FOURTEENTH of
this Certificate of Incorporation.

     FIFTEENTH:  No contract or transaction  between the  Corporation and one or
more of its directors,  officers, or stockholders or between the Corporation and
any  person (as used  herein  "person"  means  other  corporation,  partnership,
association,   firm,   trust,   joint   venture,   political   subdivision,   or
instrumentality)  or other  organization  in which one or more of its directors,
officers, or stockholders are directors,  officers,  or stockholders,  or have a
financial interest,  shall be void or voidable solely for this reason, or solely
because the director or officer is present at or  participates in the meeting of
the board or committee which  authorizes the contract or transaction,  or solely
because  his,  her or their  votes are  counted  for such  purpose,  if: (i) the
material facts as to his or her  relationship or interest and as to the contract
or  transaction  are  disclosed  or are known to the board of  directors  or the
committee,  and the board of directors or committee in good faith authorizes the
contract  or  transaction  by  the  affirmative  votes  of  a  majority  of  the
disinterested directors,  even though the disinterested directors be less than a
quorum; or (ii) the material facts as to his or her relationship or interest and
as to the contract or transaction are disclosed or are known to the stockholders
entitled to vote  thereon,  and the  contract  or  transaction  is  specifically
approved  in good faith by vote of the  stockholders;  or (iii) the  contract or
transaction  is  fair as to the  Corporation  as of the  time it is  authorized,
approved,  or ratified by the board of directors,  a committee  thereof,  or the
stockholders.  Common or interested  directors may be counted in determining the
presence  of a quorum at a meeting of the board of  directors  or of a committee
which authorizes the contract or transaction.

     I, the  undersigned,  for the purpose of forming the Corporation  under the
laws of the State of Delaware,  do make,  file,  and record this  Certificate of
Incorporation  and do  certify  that  this is my act and deed and that the facts
stated therein are true and, accordingly,  I do hereunto set my hand on this 3rd
day of May, 1994.

of the meeting or in a duly executed  waiver of notice of such meeting.  At such

stockholders  shall not be  required  to be given to any  stockholder  who shall
attend  such  meeting in person or by proxy and shall not, at the  beginning  of

vote on a matter,  present in person or by proxy,  shall  constitute a quorum at
any  meeting  of  stockholders,   except  as  otherwise  provided  by  law,  the
certificate of incorporation of the Corporation,  or these by-laws.  If a quorum
shall not be present, in person or by proxy, at any meeting of stockholders, the
stockholders  entitled to vote thereat who are  present,  in person or by proxy,

Corporation may adjourn the meeting from time to time, without notice other than
announcement  at  the  meeting  (unless  the  board  of  directors,  after  such
adjournment,  fixes a new record date for the adjourned meeting), until a quorum
shall be present,  in person or by proxy.  At any  adjourned  meeting at which a
quorum shall be present,  in person or by proxy,  any business may be transacted
which  may have  been  transacted  at the  original  meeting  had a quorum  been
present;  provided that, if the adjournment is for more than 30 days or if after
the adjournment a new record date is fixed for the adjourned  meeting,  a notice
of the adjourned  meeting shall be given to each  stockholder of record entitled

     2.7 Required  Vote;  Withdrawal of Quorum.  When a quorum is present at any
meeting,  the vote of the  holders  of at least a  majority  of the  outstanding
shares entitled to vote who are present, in person or by proxy, shall decide any
question  brought before such meeting,  unless the question is one on which,  by
express   provision  of  statute,   the  certificate  of  incorporation  of  the
Corporation,  or these by-laws, a different vote is required, in which case such
express  provision  shall govern and control the decision of such question.  The
stockholders  present at a duly  constituted  meeting  may  continue to transact
business   until   adjournment,   notwithstanding   the   withdrawal  of  enough
stockholders to leave less than a quorum.

     2.8  Method  of  Voting;  Proxies.  Except  as  otherwise  provided  in the
certificate of  incorporation  of the  Corporation  or by law, each  outstanding
share,  regardless  of  class,  shall be  entitled  to one  vote on each  matter
submitted to a vote at a meeting of  stockholders.  Elections of directors  need
not be by written  ballot.  At any meeting of  stockholders,  every  stockholder
having  the right to vote may vote  either in person or by a proxy  executed  in
writing by the stockholder or by his duly authorized attorney-in-fact. Each such
proxy shall be filed with the Secretary of the Corporation before or at the time
of the  meeting.  No proxy shall be valid after three years from the date of its
execution,  unless  otherwise  provided in the proxy.  If no date is stated in a
proxy,  such proxy shall be  presumed  to have been  executed on the date of the
meeting  at which it is to be  voted.  Each  proxy  shall  be  revocable  unless
expressly  provided  therein to be  irrevocable  and  coupled  with an  interest
sufficient  in law to  support an  irrevocable  power or unless  otherwise  made
irrevocable by law.

     2.9 Record Date.  For the purpose of determining  stockholders  entitled to
notice of or to vote at any meeting of stockholders, or any adjournment thereof,
or  entitled  to  receive  payment  of any  dividend  or other  distribution  or
allotment  of any rights,  or entitled to exercise  any rights in respect of any
change,  conversion, or exchange of stock or for the purpose of any other lawful
action,  the board of directors  may fix a record date,  which record date shall
not precede the date upon which the resolution fixing the record date is adopted
by the board of directors, for any such determination of stockholders, such date
in any case to be not more than 60 days and not less than ten days prior to such
meeting  nor more than 60 days prior to any other  action.  If no record date is
fixed:

          (i) The record date for determining stockholders entitled to notice of
     or to vote at a meeting of  stockholders  shall be at the close of business
     on the day next preceding the day on which notice is given or, if notice is
     waived, at the close of business on the day next preceding the day on which
     the meeting is held.

          (ii)  The  record  date for  determining  stockholders  for any  other
     purpose  shall be at the close of business on the day on which the board of
     directors adopts the resolution relating thereto.

          (iii) A determination  of stockholders of record entitled to notice of
     or to vote at a meeting of  stockholders  shall apply to any adjournment of
     the meeting;  provided,  however, that the board of directors may fix a new
     record date for the adjourned meeting.

     2.10 Conduct of Meeting. The Chairman of the Board, if such office has been
filled,  and,  if not or if the  Chairman  of the Board is  absent or  otherwise
unable to act, the President shall preside at all meetings of stockholders.  The
Secretary shall keep the records of each meeting of stockholders. In the absence
or  inability  to act of any  such  officer,  such  officer's  duties  shall  be
performed  by the  officer  given  the  authority  to act  for  such  absent  or
non-acting  officer  under  these  by-laws or by some  person  appointed  by the
meeting.

     2.11  Stockholder  Proposals and Nominations of Persons for Election to the
Board  of  Directors.  Nominations  of  persons  for  election  to the  board of
directors of the  corporation  and the proposal of business to be  considered by
the  stockholders  may be made at an annual  meeting  of  stockholders  only (a)
pursuant to the corporation's  notice of meeting,  (b) by or at the direction of
the board of directors,  or (c) by any  stockholder of the corporation who was a
stockholder  of record at the time of  giving  of notice  provided  for in these
by-laws, who is entitled to vote at the meeting and who complies with the notice
procedures set forth in this by-law.

     For  nominations or other business to be properly  brought before an annual
meeting by a stockholder pursuant to clause (c) of the foregoing paragraph,  (1)
the  stockholder  must have  given  timely  notice  thereof  in  writing  to the
secretary of the  corporation,  (2) such  business  must be a proper  matter for
stockholder  action under the General  Corporation  Law of Delaware,  (3) if the
stockholder,  or the  beneficial  owner on whose  behalf  any such  proposal  or
nomination is made, has provided the corporation with a Solicitation  Notice, as
that term is defined in subclause  (c)(iii) of this paragraph,  such stockholder
or  beneficial  owner must,  in the case of a proposal,  have  delivered a proxy
statement  and form of proxy  to  holders  of at  least  the  percentage  of the
corporation's  voting shares  required  under  applicable  law to carry any such
proposal, or, in the case of a nomination or nominations, have delivered a proxy
statement  and form of proxy to holders  of a  percentage  of the  corporation's
voting shares reasonably believed by such stockholder or beneficial holder to be
sufficient  to elect the nominee or nominees  proposed to be  nominated  by such
stockholder,  and must,  in either case,  have  included in such  materials  the
Solicitation  Notice and (4) if no Solicitation Notice relating thereto has been
timely provided  pursuant to this section,  the stockholder or beneficial  owner
proposing  such  business  or  nomination  must not have  solicited  a number of
proxies  sufficient to have required the delivery of such a Solicitation  Notice
under this section.  To be timely, a stockholder's  notice shall be delivered to
the  secretary of the  corporation  at the  principal  executive  offices of the
corporation not less than 60 or more than 90 days prior to the first anniversary
(the  "Anniversary") of the date on which the corporation first mailed its proxy
materials for the preceding  year's annual  meeting of  stockholders;  provided,
however,  that if the date of the annual  meeting is advanced  more than 30 days
prior to or delayed by more than 30 days after the  anniversary of the preceding
year's  annual  meeting,  notice  by the  stockholder  to be  timely  must be so
delivered  not later than the close of business on the later of (i) the 90th day
prior to such  annual  meeting or (ii) the 10th day  following  the day on which
public   announcement   of  the  date  of  such  meeting  is  first  made.  Such
stockholder's  notice  shall  be  set  forth  (a) as to  each  person  whom  the
stockholder  proposes to nominate for election or  reelection  as a director all
information  relating to such person as would be  required  to be  disclosed  in
solicitations of proxies for the election of such nominees as directors pursuant
to  Regulation  14A under the  Securities  Exchange Act of 1934, as amended (the
"Exchange  Act"),  and such person's  written  consent to serve as a director if
elected;  (b) as to any other  business that the  stockholder  proposes to bring
before the  meeting,  a brief  description  of such  business,  the  reasons for
conducting  such  business  at the  meeting  and any  material  interest in such
business of such  stockholder and the beneficial  owner, if any, on whose behalf
the  proposal  is made;  (c) as to the  stockholder  giving  the  notice and the
beneficial owner, if any, on whose behalf the nomination or proposal is made (i)
the name and address of such  stockholder,  as they appear on the  corporation's
books, and of such beneficial  owner, (ii) the class and number of shares of the
corporation  that are owned  beneficially  and of record by such stockholder and
such beneficial  owner,  and (iii) whether either such stockholder or beneficial
owner  intends to deliver a proxy  statement and form of proxy to holders of, in
the case of a proposal,  at least the  percentage  of the  corporation's  voting
shares required under  applicable law to carry the proposal or, in the case of a
nomination or nominations,  a sufficient  number of holders of the corporation's
voting  shares to elect such  nominee or nominees (an  affirmative  statement of
such intent, a "Solicitation Notice").

     Only persons  nominated in accordance with the procedures set forth in this
by-law shall be eligible to serve as directors and only such  business  shall be
conducted at an annual meeting of stockholders as shall have been brought before
the meeting in accordance  with the  procedures  set forth in this section.  The
chair of the meeting  shall have the power and the duty to  determine  whether a
nomination  or any business  proposed to be brought  before the meeting has been
made in accordance  with the  procedures  set forth in these by-laws and, if any
proposed  nomination or business is not in  compliance  with these  by-laws,  to
declare  that  such  defective  proposed  business  or  nomination  shall not be
presented for stockholder action at the meeting and shall be disregarded.

     For  the  purposes  of  this  section,  "public  announcement"  shall  mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable  national news service or in a document  publicly filed by
the corporation with the Securities and Exchange  Commission pursuant to Section
13, 14 or 15(d) of the Exchange Act."

     2.12  Inspectors.  The board of directors may, in advance of any meeting of
stockholders,  appoint  one or more  inspectors  to act at such  meeting  or any
adjournment  thereof. If any of the inspectors so appointed shall fail to appear
or act, the chairman of the meeting shall, or if inspectors  shall not have been
appointed, the chairman of the meeting may, appoint one or more inspectors. Each
inspector, before entering upon the discharge of his duties, shall take and sign
an oath  faithfully  to execute the duties of  inspector  at such  meeting  with
strict  impartiality  and according to the best of his ability.  The  inspectors
shall  determine  the  number  of  shares of  capital  stock of the  Corporation
outstanding  and the voting power of each,  the number of shares  represented at
the meeting,  the existence of a quorum,  and the validity and effect of proxies
and shall receive votes, ballots, or consents, hear and determine all challenges
and questions  arising in connection with the right to vote,  count and tabulate
all votes, ballots, or consents,  determine the results, and do such acts as are
proper to conduct the  election or vote with  fairness to all  stockholders.  On
request of the chairman of the meeting,  the  inspectors  shall make a report in
writing  of any  challenge,  request,  or  matter  determined  by them and shall
execute a  certificate  of any fact found by them.  No director or candidate for
the office of director  shall act as an inspector  of an election of  directors.
Inspectors need not be stockholders.

                            ARTICLE THREE: DIRECTORS

     3.1  Management.  The  business and  property of the  Corporation  shall be
managed by the board of directors.  Subject to the restrictions  imposed by law,
the certificate of incorporation of the Corporation, or these by-laws, the board
of directors may exercise all the powers of the Corporation.

     3.2 Number;  Qualification;  Election;  Term. The number of directors which
shall constitute the entire board of directors shall be not less than three. The
first board of directors  shall consist of the number of directors  named in the
certificate  of  incorporation  of the  Corporation  or, if no directors  are so
named,  shall consist of the number of directors elected by the  incorporator(s)
at an  organizational  meeting or by unanimous  written consent in lieu thereof.
Thereafter,  within the limits above  specified,  the number of directors  which
shall constitute the entire board of directors shall be determined by resolution
of the board of directors.  Except as otherwise required by law, the certificate
of incorporation of the  Corporation,  or these by-laws,  the directors shall be
elected  at an annual  meeting  of  stockholders  at which a quorum is  present.
Directors  shall be elected by a plurality of the votes of the shares present in
person  or  represented  by  proxy  and  entitled  to  vote on the  election  of
directors. At each annual meeting of stockholders,  directors elected to succeed
those whose terms are then  expiring  shall be elected for a full term of office
expiring at the third  succeeding  annual  meeting of  stockholders  after their
election.  Except as otherwise  required by law, whenever the holders of any one
or more series of preferred stock shall have the right,  voting  separately as a
class,  to elect  one or more  directors  of the  corporation,  the terms of the
director  or  directors  elected  by  such  holders  shall  expire  at the  next
succeeding annual meeting of stockholders. Each director shall hold office until
his successor  shall have been elected and qualified or until his earlier death,
resignation  or  removal.  Directors  need  not  be  residents  of  Delaware  or
stockholders  of the  corporation.  Each  director must have attained the age of
majority.

     3.3 Change in Number.  No decrease in the number of directors  constituting
the entire board of directors  shall have the effect of  shortening  the term of
any incumbent director.

     3.4   Vacancies.   Unless   otherwise   provided  in  the   certificate  of
incorporation,  any vacancy or any newly-created directorship resulting from any
increase in the  authorized  number of directors  may be filled by a majority of
the directors then in office,  though less than a quorum,  or by the affirmative
vote of two directors if there are only two directors remaining,  or by the sole
remaining  director.  Any  director  elected by one or more  directors to fill a
newly  created  directorship  or other  vacancy shall hold office until the next
election of the class for which such directors  shall have been chosen and until
his or her  successor  shall have been  elected and  qualified,  or, if earlier,
until his death, resignation,  or removal from office. If there are no directors
in office,  an  election  of  directors  may be held in the manner  provided  by
statute.  When one or more  directors  shall resign from the board of directors,
effective  at a  future  date,  a  majority  of the  directors  then in  office,
including those who have so resigned,  shall have the power to fill such vacancy
or  vacancies,  the  vote  thereon  to take  effect  when  such  resignation  or
resignations  shall  become  effective,  and each  director so chosen shall hold
office as  provided  in these  by-laws  with  respect  to the  filling  of other
vacancies.

     3.5 Meetings of Directors.  The  directors may hold their  meetings and may
have an  office  and keep the  books of the  Corporation,  except  as  otherwise
provided  by  statute,  in such place or places  within or without  the State of
Delaware as the board of directors  may from time to time  determine or as shall
be specified in the notice of such meeting or duly executed  waiver of notice of
such meeting.

     3.6 First Meeting. Each newly elected board of directors may hold its first
meeting for the purpose of organization  and the  transaction of business,  if a
quorum is present, immediately after and at the same place as the annual meeting
of stockholders, and no notice of such meeting shall be necessary.

     3.7  Election of Officers.  At the first  meeting of the board of directors
after each annual  meeting of  stockholders  at which a quorum shall be present,
the board of directors shall elect the officers of the Corporation.

     3.8 Regular  Meetings.  Regular meetings of the board of directors shall be
held at such  times  and  places  as shall be  designated  from  time to time by
resolution of the board of directors.  Notice of such regular meetings shall not
be required.

     3.9 Special  Meetings.  Special meetings of the board of directors shall be
held whenever called by the Chairman of the Board,  the President,  or any other
two directors.

     3.10 Notice.  The  Secretary  shall give notice of each special  meeting to
each  director at least 24 hours before the meeting.  Notice of any such meeting
need not be given to any director who shall, either before or after the meeting,
submit a signed  waiver  of  notice or who shall  attend  such  meeting  without
protesting, prior to or at its commencement,  the lack of notice to him. Neither
the  business  to be  transacted  at, nor the purpose of, any regular or special
meeting of the board of  directors  need be specified in the notice or waiver of
notice of such meeting.

     3.11 Quorum;  Majority  Vote. At all meetings of the board of directors,  a
majority of the  directors  fixed in the manner  provided in these by-laws shall
constitute a quorum for the  transaction  of business.  If at any meeting of the
board of  directors  there be less than a quorum  present,  a majority  of those
present or any director solely present may adjourn the meeting from time to time
without further  notice.  Unless the act of a greater number is required by law,
the certificate of incorporation of the Corporation,  or these by-laws,  the act
of a  majority  of the  directors  present  at a meeting at which a quorum is in
attendance  shall be the act of the  board of  directors.  At any time  that the
certificate of incorporation of the Corporation  provides that directors elected
by the  holders  of a class or series of stock  shall have more or less than one
vote per director on any matter,  every reference in these by-laws to a majority
or other  proportion of directors shall refer to a majority or other  proportion
of the votes of such directors.

     3.12  Procedure.  At meetings of the board of directors,  business shall be
transacted  in such  order as from  time to time  the  board  of  directors  may
determine.  The Chairman of the Board,  if such office has been filled,  and, if
not or if the  Chairman of the Board is absent or  otherwise  unable to act, the
President  shall  preside  at all  meetings  of the board of  directors.  In the
absence or inability to act of either such officer,  a chairman  shall be chosen
by the board of directors from among the directors present. The Secretary of the
Corporation shall act as the secretary of each meeting of the board of directors
unless the board of directors appoints another person to act as secretary of the
meeting.  The board of directors  shall keep regular  minutes of its proceedings
which shall be placed in the minute book of the Corporation.

     3.13 Presumption of Assent. A director of the Corporation who is present at
the meeting of the board of directors at which action on any corporate matter is
taken shall be presumed to have  assented to the action unless his dissent shall
be entered in the  minutes  of the  meeting or unless he shall file his  written
dissent to such action with the person acting as secretary of the meeting before
the adjournment  thereof or shall forward any dissent by certified or registered
mail to the Secretary of the  Corporation  immediately  after the adjournment of
the  meeting.  Such right to dissent  shall not apply to a director who voted in
favor of such action.

     3.14 Action Without a Meeting. Any action required or permitted to be taken
at any meeting of the board of directors may be taken without a meeting, without
prior notice and without a vote, if all members of the board consent  thereto in
writing  and  the  writing  or  writings  are  filed  with  the  minutes  of the
proceedings of the board.

     3.15  Compensation.  The board of directors shall have the authority to fix
the  compensation,  including  fees  and  reimbursement  of  expenses,  paid  to
directors  for  attendance  at  regular  or  special  meetings  of the  board of
directors or any committee  thereof;  provided,  that nothing  contained  herein
shall be construed to preclude any director from serving the  Corporation in any
other capacity or receiving compensation therefor.

                            ARTICLE FOUR: COMMITTEES

     4.1  Designation.  The board of directors  may, by resolution  adopted by a
majority of the entire board of directors, designate one or more committees.

     4.2 Number;  Qualification;  Term.  Each committee  shall consist of one or
more directors appointed by resolution adopted by a majority of the entire board
of directors. The number of committee members may be increased or decreased from
time to time  by  resolution  adopted  by a  majority  of the  entire  board  of
directors.  Each committee  member shall serve as such until the earliest of (i)
the  expiration  of his term as director,  (ii) his  resignation  as a committee
member or as a  director,  or (iii) his  removal as a  committee  member or as a
director.

     4.3 Authority.  Each  committee,  to the extent  expressly  provided in the
resolution  establishing such committee,  shall have and may exercise all of the
authority  of the board of  directors  in the  management  of the  business  and
property of the Corporation  except to the extent  expressly  restricted by law,
the certificate of incorporation of the Corporation, or these by-laws.

     4.4 Committee  Changes.  The board of directors shall have the power at any
time to fill  vacancies  in, to change the  membership  of, and to discharge any
committee.

     4.5 Alternate  Members of Committees.  The board of directors may designate
one or more directors as alternate members of any committee.  Any such alternate
member may  replace  any  absent or  disqualified  member at any  meeting of the
committee.  If no  alternate  committee  members  have  been so  appointed  to a
committee or each such alternate committee member is absent or disqualified, the
member or members of such committee  present at any meeting and not disqualified
from  voting,  whether or not he or they  constitute a quorum,  may  unanimously
appoint  another  member of the board of  directors to act at the meeting in the
place of any such absent or disqualified member.

     4.6 Regular Meetings. Regular meetings of any committee may be held without
notice  at such  time and  place as may be  designated  from time to time by the
committee and communicated to all members thereof.

     4.7  Special  Meetings.  Special  meetings  of any  committee  may be  held
whenever  called by any  committee  member.  The  committee  member  calling any
special meeting shall cause notice of such special  meeting,  including  therein
the time and place of such special meeting, to be given to each committee member
at least two days  before  such  special  meeting.  Neither  the  business to be
transacted at, nor the purpose of, any special  meeting of any committee need be
specified in the notice or waiver of notice of any special meeting.

     4.8 Quorum;  Majority Vote. At meetings of any committee, a majority of the
number of members designated by the board of directors shall constitute a quorum
for the transaction of business.  If a quorum is not present at a meeting of any
committee,  a majority of the members  present may adjourn the meeting from time
to time,  without  notice other than an  announcement  at the  meeting,  until a
quorum is present.  The act of a majority of the members  present at any meeting
at which a quorum is in attendance  shall be the act of a committee,  unless the
act of a greater number is required by law, the certificate of  incorporation of
the Corporation, or these by-laws.

     4.9 Minutes.  Each committee  shall cause minutes of its  proceedings to be
prepared and shall report the same to the board of directors upon the request of
the board of directors.  The minutes of the  proceedings of each committee shall
be delivered to the  Secretary of the  Corporation  for  placement in the minute
books of the Corporation.

     4.10  Compensation.  Committee  members may, by  resolution of the board of
directors,  be  allowed a fixed sum and  expenses  of  attendance,  if any,  for
attending any committee meetings or a stated salary.

     4.11 Responsibility. The designation of any committee and the delegation of
authority  to it shall not  operate to  relieve  the board of  directors  or any
director of any responsibility imposed upon it or such director by law.

                              ARTICLE FIVE: NOTICE

     5.1 Method.  Whenever by statute,  the certificate of  incorporation of the
Corporation,  or these by-laws,  notice is required to be given to any committee
member,  director, or stockholder and no provision is made as to how such notice
shall be given, personal notice shall not be required and any such notice may be
given (a) in writing,  by mail,  postage  prepaid,  addressed to such  committee
member,  director,  or  stockholder at his address as it appears on the books or
(in the case of a stockholder) the stock transfer records of the Corporation, or
(b) by any other method permitted by law (including but not limited to overnight
courier  service,  telegram,  telex,  or  facsimile).  Any  notice  required  or
permitted to be given by mail shall be deemed to be  delivered  and given at the
time when the same is  deposited  in the United  States mail as  aforesaid.  Any
notice  required or permitted to be given by overnight  courier service shall be
deemed to be delivered and given at the time  delivered to such service with all
charges prepaid and addressed as aforesaid.  Any notice required or permitted to
be given by telegram,  telex,  or telefax  shall be deemed to be  delivered  and
given  at the time  transmitted  with  all  charges  prepaid  and  addressed  as
aforesaid.

     5.2 Waiver. Whenever any notice is required to be given to any stockholder,
director,  or committee member of the Corporation by statute, the certificate of
incorporation of the Corporation,  or these by-laws, a waiver thereof in writing
signed by the person or persons entitled to such notice, whether before or after
the time  stated  therein,  shall be  equivalent  to the giving of such  notice.
Attendance of a stockholder,  director,  or committee  member at a meeting shall
constitute a waiver of notice of such meeting,  except where such person attends
for the express  purpose of objecting to the  transaction of any business on the
ground that the meeting is not lawfully called or convened.

                              ARTICLE SIX: OFFICERS

     6.1 Number;  Titles;  Term of Office. The officers of the Corporation shall
be a President,  a Secretary,  and such other officers as the board of directors
may from time to time elect or appoint,  including a Chairman of the Board,  one
or more Vice  Presidents  (with  each Vice  President  to have such  descriptive
title, if any, as the board of directors shall determine), and a Treasurer. Each
officer shall hold office until his  successor  shall have been duly elected and
shall have  qualified,  until his death,  or until he shall resign or shall have
been removed in the manner hereinafter provided.  Any two or more offices may be
held by the  same  person.  None of the  officers  need  be a  stockholder  or a
director of the Corporation or a resident of the State of Delaware.

     6.2  Removal.  Any officer or agent  elected or  appointed  by the board of
directors may be removed by the board of directors  whenever in its judgment the
best interest of the Corporation will be served thereby,  but such removal shall
be without  prejudice to the contract rights,  if any, of the person so removed.
Election  or  appointment  of an  officer  or agent  shall not of itself  create
contract rights.

     6.3 Vacancies.  Any vacancy  occurring in any office of the Corporation (by
death,  resignation,  removal,  or  otherwise)  may be  filled  by the  board of
directors.

     6.4  Authority.  Officers shall have such authority and perform such duties
in the management of the  Corporation as are provided in these by-laws or as may
be determined by  resolution  of the board of directors  not  inconsistent  with
these by-laws.

     6.5 Compensation. The compensation, if any, of officers and agents shall be
fixed from time to time by the board of directors;  provided,  however, that the
board of directors may delegate the power to determine the  compensation  of any
officer and agent  (other than the officer to whom such power is  delegated)  to
the Chairman of the Board or the President.

     6.6  Chairman of the Board.  The  Chairman of the Board,  if elected by the
board of  directors,  shall have such powers and duties as may be  prescribed by
the board of  directors.  Such  officer  shall  preside at all  meetings  of the
stockholders  and  of  the  board  of  directors.  Such  officer  may  sign  all
certificates for shares of stock of the Corporation.

     6.7 President.  The President shall be the chief  executive  officer of the
Corporation  and,  subject  to the board of  directors,  he shall  have  general
executive  charge,  management,  and control of the properties and operations of
the  Corporation  in the ordinary  course of its business,  with all such powers
with respect to such properties and operations as may be reasonably  incident to
such  responsibilities.  If the board of directors has not elected a Chairman of
the Board or in the absence or  inability  to act of the  Chairman of the Board,
the President  shall  exercise all of the powers and discharge all of the duties
of the Chairman of the Board. As between the Corporation and third parties,  any
action taken by the President in the  performance  6f the duties of the Chairman
of the Board shall be conclusive evidence that there is no Chairman of the Board
or that the Chairman of the Board is absent or unable to act.

     6.8 Vice Presidents.  Each Vice President shall have such powers and duties
as may be assigned to him by the board of directors,  the Chairman of the Board,
or the President, and (in order of their seniority as determined by the board of
directors or, in the absence of such determination,  as determined by the length
of time they have held the office of Vice  President)  shall exercise the powers
of the President  during that officer's  absence or inability to act. As between
the Corporation  and third parties,  any action taken by a Vice President in the

and duties as may be assigned to him by the board of directors,  the Chairman of

determination,  as determined by the length of time they have held the office of
Assistant  Treasurer)  shall  exercise the powers of the  Treasurer  during that
officer's absence or inability to act.

     6.11  Secretary.  Except  as  otherwise  provided  in  these  by-laws,  the

                  ARTICLE SEVEN: CERTIFICATES AND SHAREHOLDERS

     7.1  Certificates  for  Shares.  Certificates  for  shares  of stock of the
Corporation  shall  be in  such  form as  shall  be  approved  by the  board  of
directors.  The certificates shall be signed by the Chairman of the Board or the
President  or a Vice  President  and  also  by  the  Secretary  or an  Assistant
Secretary or by the Treasurer or an Assistant Treasurer.  Any and all signatures
on the  certificate  may be a  facsimile  and may be sealed with the seal of the
Corporation or a facsimile thereof. If any officer, transfer agent, or registrar
who has signed, or whose facsimile signature has been placed upon, a certificate
has  ceased  to be such  officer,  transfer  agent,  or  registrar  before  such
certificate is issued,  such  certificate may be issued by the Corporation  with
the same effect as if he were such officer,  transfer agent, or registrar at the
date of issue.  The certificates  shall be  consecutively  numbered and shall be
entered in the books of the Corporation as they are issued and shall exhibit the
holder's name and the number of shares.

     7.2 Replacement of Lost or Destroyed  Certificates.  The board of directors
may  direct  a new  certificate  or  certificates  to be  issued  in  place of a
certificate or certificates theretofore issued by the Corporation and alleged to
have been lost or destroyed, upon the making of an affidavit of that fact by the
person claiming the certificate or certificates  representing  shares to be lost
or destroyed.  When  authorizing such issue of a new certificate or certificates
the board of directors may, in its  discretion  and as a condition  precedent to
the issuance thereof, require the owner of such lost or destroyed certificate or
certificates, or his legal representative,  to advertise the same in such manner
as it shall  require  and/or  to give the  Corporation  a bond  with a surety or
sureties  satisfactory  to the  Corporation  in  such  sum as it may  direct  as
indemnity against any claim, or expense resulting from a claim, that may be made
against the Corporation with respect to the certificate or certificates  alleged
to have been lost or destroyed.

     7.3  Transfer  of  Shares.  Shares  of  stock of the  Corporation  shall be
transferable  only on the books of the  Corporation  by the  holders  thereof in
person or by their duly  authorized  attorneys  or legal  representatives.  Upon
surrender to the  Corporation  or the  transfer  agent of the  Corporation  of a
certificate  representing shares duly endorsed or accompanied by proper evidence
of  succession,  assignment,  or authority to transfer,  the  Corporation or its
transfer  agent shall issue a new  certificate to the person  entitled  thereto,
cancel the old certificate, and record the transaction upon its books.

     7.4 Registered Stockholders. The Corporation shall be entitled to treat the
holder of record of any share or shares of stock as the  holder in fact  thereof
and,  accordingly,  shall not be bound to recognize any equitable or other claim
to or interest in such share or shares on the part of any other person,  whether
or not it shall  have  express  or other  notice  thereof,  except as  otherwise
provided by law.

     7.5 Regulations.  The board of directors shall have the power and authority
to make all such rules and  regulations  as they may deem  expedient,  including
without  limitation a requirement  that a transferor  furnish a legal opinion or
such other evidence as is reasonably  satisfactory  to the  Corporation  and its
counsel that any proposed  transfer of shares does not violate the  registration
requirements  of any state or  federal  securities  law,  concerning  the issue,
transfer,  and  registration or the  replacement of  certificates  for shares of
stock of the Corporation.

     7.6 Legends.  The board of directors  shall have the power and authority to
provide that certificates  representing shares of stock bear such legends as the
board of directors  deems  appropriate to assure that the  Corporation  does not
become  liable  for  violations  of federal  or state  securities  laws or other
applicable law.

                     ARTICLE EIGHT: MISCELLANEOUS PROVISIONS

board of directors,  or committee by means of a conference  telephone or similar
communications  equipment by means of which persons participating in the meeting
can hear each other,  and  participation  in a meeting  pursuant to this section

transaction  of any  business  on the ground  that the  meeting is not  lawfully
called or convened.

or inoperative for any reason, the remaining parts, so far as it is possible and
reasonable, shall remain valid and operative.

other instrument executed by the Corporation through its duly authorized officer
or  officers,  the  attestation  to  such  execution  by  the  Secretary  of the
Corporation  shall not be  necessary  to  constitute  such deed,  deed of trust,
mortgage,  or other  instrument  a valid  and  binding  obligation  against  the
Corporation  unless  the  resolutions,   if  any,  of  the  board  of  directors
authorizing such execution expressly state that such attestation is necessary.
