PART I ITEM 1. BUSINESS (a) GENERAL DEVELOPMENT OF BUSINESS Gentex Corporation (the "Company") designs, develops, manufactures and markets proprietary products employing electro-optic technology: automatic-dimming rearview mirrors and fire protection products. The Company was organized in 1974 to manufacture residential smoke detectors, a product line that has since evolved into a more sophisticated group of fire protection products for commercial applications. In 1982, the Company introduced an automatic interior rearview mirror that was the first commercially successful glare-control product offered as an alternative to the conventional, manual day/night mirror. In 1987, the Company introduced its interior Night Vision Safety(TM) (NVS(R)) Mirror, an electrochromic (EC) automatic-dimming interior rearview mirror, providing the first successful commercial application of electrochromic technology in the automotive industry and world. Through the use of electrochromic technology, this mirror is continually variable and automatically darkens to the degree required to eliminate rearview headlight glare. In 1991, the Company introduced its exterior Night Vision Safety Mirror Sub-Assembly, which works as a complete glare-control system with the interior NVS Mirror. In 1997, the Company began making volume shipments of three new exterior mirror sub-assembly products: thin glass flat, convex and aspheric. During 2001 and 2002, the Company began making shipments of its NVS mirrors for a number of mid-sized, medium-priced vehicles, including the Toyota Camry, Matrix and Corolla; Ford Taurus and Mercury Sable; Volkswagen Passat, Jetta, Golf GTI and Beetle; Nissan Altima; Opel Cross Car Line; Chrysler Sebring Coupe; Hyundai Santa Fe and Sonata; and Kia Optima and Sorento. The Company's annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports will be made available free of charge through the Investor Information section of the Company's Internet website (http://www.gentex.com) as soon as practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission. (b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS See Note 8 to the Consolidated Financial Statements filed with this report. (c) NARRATIVE DESCRIPTION OF BUSINESS The Company currently manufactures electro-optic products, including automatic-dimming rearview mirrors for the automotive industry and fire protection products primarily for the commercial building industry. AUTOMATIC-DIMMING REARVIEW MIRRORS Interior NVS Mirrors. In 1987, the Company achieved a significant technological breakthrough by applying electrochromic technology to the glare-sensing capabilities of its Motorized Mirror. Through the use of this technology, the mirror gradually darkens to the degree necessary to eliminate rearview glare from following vehicle headlights. The NVS Mirror offers all of the continuous reflectance levels between its approximate 85% full-reflectance state and its 7% least-reflectance state, taking just a few seconds to span the entire range. Special electro-optic sensors in the mirror detect glare and electronic circuitry supplies electricity to darken the mirror to only the precise level required to eliminate glare, allowing the driver to maintain maximum vision. This is accomplished by the utilization of two layers of precision glass with special conductive coatings that are separated by the Company's proprietary electrochromic materials. When the appropriate light differential is detected, an electric current causes the electrochromic material to darken, decreasing the mirror's reflectance, thereby eliminating glare. -2-

During 1991, the Company began shipping the first advanced-feature interior NVS Mirror, the NVS Headlamp Control Mirror, an automatic-dimming mirror that automatically turns car head- and taillamps "on" and "off" at dusk and dawn in response to the level of light observed. During 1993, the Company began shipping its NVS Compass Mirror, with an electronic compass that automatically compensates for changes in the earth's magnetic field. During 1997, the Company began shipping a new interior NVS Mirror that digitally displays either a compass or outside temperature reading. During 1998, the Company began shipping new compass mirrors with its proprietary light-emitting diode (LED) map lamps, a major improvement over mirrors with standard incandescent map lamps. At the beginning of 2000, the Company began shipping to General Motors interior NVS Mirrors that serve as the driver interface for the OnStar(R) System, an in-vehicle safety, security and information service using Global Positioning System (GPS) satellite technology. The Company shipped approximately 4,609,000 interior NVS Mirrors in 2000, approximately 5,000,000 in 2001, and approximately 6,305,000 in 2002. During 2001 and 2002, the Company began making shipments of its NVS Mirrors for a number of mid-sized, medium-priced vehicles, including the Toyota Camry, Matrix and Corolla; Ford Taurus and Mercury Sable; Volkswagen Passat, Jetta, Golf GTI and Beetle; Nissan Altima; Opel Cross Car Line; Chrysler Sebring Coupe; Hyundai Santa Fe and Sonata; and Kia Optima and Sorento. During 2002, the growth in unit shipments resulted from increased penetration of light vehicles manufactured worldwide. The Company's interior NVS(R) Mirrors are standard equipment or factory-or distributor/dealer-installed options on certain trim levels of the following 2003 and 2003-1/2 vehicle models: TABLE 1.

Exterior NVS(R) Mirror Sub-Assemblies. The Company has devoted substantial research and development efforts to the development of its electrochromic technology to permit its use in exterior rearview mirrors. Exterior NVS(R) mirrors are controlled by the sensors and electronic circuitry in the interior NVS(R) Mirror, and both the interior and exterior mirrors dim simultaneously. During 1991, the Company's efforts culminated in a design that is intended to provide acceptable long-term performance in all environments likely to be encountered. In 1994, the Company began shipments of its complete three-mirror system, including the convex (curved glass) wide-angle NVS(R) Mirror to BMW. During 1997, the Company began making volume shipments of three new exterior mirror products - - thin glass flat, convex and aspheric. During 2001 and 2002, the Company began making shipments of the world's first exterior automatic-dimming mirrors with built-in turn-signal indicators to Southeast Toyota and General Motors. The Company currently sells its exterior NVS(R) Mirror Sub-Assemblies to exterior mirror suppliers of General Motors, DaimlerChrysler, Ford, Audi, BMW, Bentley, Fiat, Jaguar, Land Rover, Opel, Rolls Royce, Infiniti, Mitsubishi, Nissan and Toyota, who assemble the exterior NVS Mirror Sub-Assemblies into full mirror units for subsequent resale to the automakers. The Company shipped approximately 2,148,000 exterior NVS Mirror Sub-Assemblies during 2000, approximately 2,181,000 in 2001, and approximately 2,500,000 in 2002. During 2002, unit shipment growth primarily resulted from the increased penetration of light vehicles in North America and Europe. The exterior NVS Mirror is standard equipment or a factory- or distributor/dealer-installed option on certain trim levels of the following 2003 and 2003-1/2 vehicle models: TABLE 2.

The Company plans to continue introducing additional advanced-feature NVS(R) Mirrors. Advanced-feature NVS(R) Mirrors currently being offered by the Company include the NVS Headlamp Control Mirror, the NVS(R) Lighted Mirror with LED map lamps, the NVS Compass Mirror, the NVS Mirror with Remote Keyless Entry, the NVS Compass/Temperature Mirror, the NVS Dual Display Compass/Temperature Mirror, the NVS telematics mirrors and the NVS HomeLink(R) Mirror. During 2001, the Company announced a revolutionary new technology, called SmartBeam, that uses a custom, active-pixel, CMOS (complementary -5-

metal oxide semiconductor) sensor, that maximizes a driver's forward vision by significantly improving utilization of the vehicle's highbeam headlamps during nighttime driving. The Company has received product planning commitments from two major automotive OEM customers for certain 2005 model year vehicles. In addition, the Company announced a new ALS (Active Light Sensor) technology as a cost-effective, improved-performance, intelligent CMOS light sensor to control the dimming of its rearview mirrors, and the Company began making volume shipments of mirrors incorporating ALS in 2002. Also during 2001, the Company developed a new microphone designed specifically for use in the automotive environment for telematics applications. The first volume Gentex microphone application will be part of DaimlerChrysler's "U-Connect(R)" telematics system, beginning in 2003. Of particular importance to the Company has been the development of its electrochromic technology for use in complete 3-mirror systems. In these systems, both the driver- and passenger-side exterior NVS(R) Mirrors are controlled by the sensors and electronic circuitry in the interior rearview mirror, and the interior and both exterior mirrors dim simultaneously. In 1999, the Company announced the development of the second generation of its LED technology, which represents the first time that white light for illumination purposes can be achieved using high intensity Orca power LEDs on a cost-effective basis. LEDs as illuminators could have significant automotive and non-automotive lighting applications as they have many advantages over incandescent lamps, including extremely long life, low heat generation, lower current draw, more resistance to shock, and lower total cost of ownership. In the fourth quarter of 2001, the Company installed a new prototype microelectronics line to produce pilot production LED samples, as well as limited production quantities of Orca LED's, and SmartBeam(TM) sensors. During 2002, the Company announced a high-feature EC mirror including BCW Orca(TM) LED's for the Chrysler Sebring Coupe. Strategic discussions with potential alliance partners in the lighting industry, LED component industry and LED chip industry are continuing although discussions are taking longer than anticipated, primarily due to changing business conditions in the LED industry. The Company's success with electrochromic technology provides an opportunity for other potential commercial applications, which the Company expects to explore in the future as resources permit. Examples of possible applications of electrochromic technology include windows for both the automotive and architectural markets, sunroofs and sunglasses. Progress in adapting electrochromic technology to the specialized requirements of the window market continued in 2002. However, we believe that a commercial product will require several years of additional engineering and intellectual property development work. Markets and Marketing. The Company markets its automatic rearview mirrors to domestic and foreign automotive manufacturers under the trademarks "Night Vision Safety" or NVS Mirrors. In North America, the Company markets these products primarily through a direct sales force. The Company generally supplies NVS Mirrors to its customers worldwide under annual blanket purchase orders. The Company currently supplies NVS Mirrors to General Motors Corporation and DaimlerChrysler AG (North America) under long-term agreements. During 2000, the Company negotiated a contract extension for inside mirrors with General Motors through the 2004 model year. The long-term supply agreement with DaimlerChrysler AG extends through the 2003 model year. The Company's exterior NVS Mirror Sub-Assemblies are supplied to General Motors, Ford and DaimlerChrysler AG by means of sales to exterior mirror suppliers. During 1993, the Company established a sales and engineering office in Germany and the following year, the Company formed a German limited liability company, Gentex GmbH, to expand its sales and engineering support activities in Europe. During 1999, the Company established Gentex Mirrors, Ltd., as a sales and engineering office in the United Kingdom. During 2000, the Company established Gentex France, SAS, as a sales and engineering office in France. The Company's marketing efforts in Europe are conducted through Gentex GmbH, Gentex Mirrors, Ltd., and Gentex France SAS, with limited assistance from independent manufacturers' representatives. The Company is currently supplying mirrors for Audi, Bavarian Motor Works, A.G. (BMW), Bentley, Fiat, Jaguar, Land Rover, MG Rover, Mercedes-Benz, Opel, Rolls Royce, and Volkswagen. -6-

Since 1991, the Company has been shipping electrochromic mirror assemblies for Nissan Motor Co., Ltd. under a reciprocal distribution agreement with Ichikoh Industries, Ltd. (Ichikoh), a major Japanese supplier of automotive products. Under this agreement, Ichikoh markets the Company's automatic mirrors to certain Japanese automakers and their subsidiaries with manufacturing facilities in Asia. The arrangement involves very limited technology transfer by the Company and does not include the Company's proprietary electrochromic gel formulation. During 1993, the Company hired a sales agent to market NVS Mirrors to other Japanese automakers beyond Nissan. Subsequently in 1998, the Company established Gentex Japan, Inc., as a sales and engineering office to expand its sales and engineering support in Japan. During 1999, the Company signed an agreement with Murakami Corporation, a major Japanese mirror manufacturer, to cooperate in expanding sales of automatic-dimming mirrors using the Gentex electrochromic technology. During 2002, the Company established Gentex Technologies Korea Co., Ltd. as a sales and engineering office in Seoul, Korea. The Company is currently supplying mirrors for Daewoo/Ssangyong, Ford (Taiwan), GM (China), Hyundai, Infiniti, Kia Motors, Lexus, Mazda, Mitsubishi, Nissan, Samsung, and Toyota. Historically, new safety and comfort options have entered the original equipment automotive market at relatively low rates on "top of the line" or luxury model automobiles. As the selection rates for the options on the luxury models increase, they generally become available on more models throughout the product line and may become standard equipment. The recent trend of domestic and foreign automakers is to offer several options as a package. As consumer demand increases for a particular option, the mirror tends to be offered on more vehicles and in higher option rate packages. The Company anticipates that its NVS Mirrors will be offered as standard equipment, in higher option rate packages, and on more models as consumer awareness of the safety and comfort features becomes more well-known and acceptance grows. Since 1998, Gentex Corporation has contracted with MITO Corporation to sell several of its most popular automatic-dimming mirrors directly to consumers in the automotive aftermarket; in addition, the Company currently sells some NVS Mirrors to automotive distributors. It is management's belief that these sales have limited potential until the Company achieves a significantly higher penetration of the original equipment manufacturing market. Competition. Gentex is the leading producer of automatic rearview mirrors in the world and currently is the dominant supplier to the automotive industry with an approximate 78% market share worldwide. While the Company believes it will retain a dominant position, one other U.S. manufacturer (Magna Donnelly) is competing for sales to domestic and foreign vehicle manufacturers and is supplying a number of domestic and foreign vehicle models with its hybrid or solid polymer matrix versions of electrochromic mirrors. In addition, two Japanese manufacturers are currently supplying a number of vehicle models in Japan with solid-state electrochromic mirrors. On October 1, 2002, Magna International acquired Donnelly Corporation which is the Company's major competitor for sales of automatic-dimming rearview mirrors to domestic and foreign vehicle manufacturers and their mirror suppliers. The Company also sells certain automatic-dimming rearview mirror sub-assemblies to Magna Donnelly. The Company believes its electrochromic automatic mirrors offer significant performance advantages over competing products. However, Gentex recognizes that Magna Donnelly, a competitor and wholly-owned subsidiary of Magna International, is considerably larger than the Company and presents a more formidable competitive threat after the acquisition. There are numerous other companies in the world conducting research on various technologies, including electrochromics, for controlling light transmission and reflection. Gentex believes that the electrochromic materials and manufacturing process it uses for automotive mirrors remains the most efficient and cost-effective way to produce such products. While automatic-dimming mirrors using other technologies may eliminate glare, each of these technologies have inherent cost or performance limitations. -7-

FIRE PROTECTION PRODUCTS The Company manufactures approximately 60 different models of smoke alarms and smoke detectors, combined with over 160 different models of signaling appliances. All of the smoke detectors/alarms operate on a photoelectric principle to detect smoke. While the use of photoelectric technology entails greater manufacturing costs, the Company believes that these detectors/alarms are superior in performance to competitive devices that operate through an ionization process, and are preferred in most commercial residential occupancies. Photoelectric detectors/alarms feature low light-level detection, while ionization detectors utilize an ionized atmosphere, the electrical conductivity of which varies with changes in the composition of the atmosphere. Photoelectric detectors/alarms are widely recognized to respond more quickly to slow, smoldering fires, a common form of dwelling unit fire and a frequent cause of fire-related deaths. In addition, photoelectric detectors are less prone to nuisance alarms and do not require the use of radioactive materials necessary for ionization detectors. Photoelectric smoke detectors/alarms are now being required by an increasing number of city and state laws, and national codes. The Company's fire protection products provide the flexibility to be wired as part of multiple-function systems and consequently are generally used in fire detection systems common to large office buildings, hotels, motels, military bases, college dormitories and other commercial establishments. However, the Company also offers single-station alarms for both commercial and residential applications. While the Company does not emphasize the residential market, some of its fire protection products are used in single-family residences that utilize fire protection and security systems. The Company's detectors emit audible and/or visual signals in the immediate location of the device, and certain models are able to communicate with monitored remote stations. In recent years, the Company introduced seven new signaling products. These new product series contain over 68 variations of signals. In 2002, the Company introduced the new "selectable" candela audible/visual evacuation signal. This new signal is the only one in the fire alarm industry which will notify the control panel if its light intensity is being changed without authorization. Also in 2002, due to changes in government regulations, the Company introduced a new "selectable" ceiling horn/strobe and strobe product. This new product offering gives the Company both wall- and ceiling-mounted product offerings. In 2001, the Company introduced a new, high efficiency speaker and speaker/strobe series. Voice intelligibility is critical in life safety applications, and certain distributors throughout the United States prefer the quality of the Company's new speaker series. To meet new international requirements for visual signals, the Company developed a red-lens for the popular general evacuation signals. The new markets are all in Asia and the Company has actively pursued these new markets. Also, to meet the industry requirements for audible and visual synchronization in 2001, the Company introduced a new line of remote signals to be used in any occupancy that requires individual or supplemental notification. Markets and Marketing. The Company's fire protection products are sold directly to fire protection and security product distributors under the Company's brand name, electrical wholesale houses, and to original equipment manufacturers of fire protection systems under both the Company's brand name and private labels. The fire protection and security industries have experienced a tremendous number of mergers and consolidations during the past few years. The Company markets its fire protection products throughout the United States through regional sales managers and manufacturer representative organizations. Competition. The fire protection products industry is highly competitive in terms of both the smoke detectors and signaling appliance markets. The Company estimates that it competes principally with eleven manufacturers of smoke detection products for commercial use and approximately four manufacturers within the residential market, three of which produce photoelectric smoke detectors. In the signaling appliance markets, the Company estimates it competes with approximately eight manufacturers. While the Company faces significant competition in the sale of smoke detectors and signaling appliances, it believes that the recent introduction -8-

of new products, improvements to its existing products, its diversified product line, and the availability of special features will permit the Company to maintain its competitive position. TRADEMARKS AND PATENTS The Company owns 6 U.S. trademarks and 151 U.S. patents, 145 of which relate to electrochromic technology and/or automotive rearview mirrors. These patents expire between 2003 and 2021. The Company believes that these patents provide the Company a significant competitive advantage in the automotive rearview mirror market; however, none of these patents is required for the success of any of the Company's products. The Company also owns 1 foreign trademark and 34 foreign patents, 33 of which relate to automotive rearview mirrors. These patents expire at various times between 2003 and 2018. The Company believes that the competitive advantage derived in the relevant foreign markets for these patents is comparable to that experienced in the U.S. market. The remaining 6 U.S. patents and 1 foreign patent relate to the Company's fire protection products, and the Company believes that the competitive advantage provided by these patents is relatively small. The Company also has in process 141 U.S. patent applications, 208 foreign patent applications, and 7 trademark applications. The Company continuously seeks to improve its core technologies and apply those technologies to new and existing products. As those efforts produce patentable inventions, the Company expects to file appropriate patent applications. MISCELLANEOUS The Company considers itself to be engaged in the manufacture and sale of automatic rearview mirrors for the automotive industry and fire protection products for the commercial building industry. The Company has several important customers within the automotive industry, three of which each account for 10% or more of the Company's annual sales: General Motors Corporation, DaimlerChrysler AG, and Toyota Motor Corporation. The loss of any of these customers could have a material adverse effect on the Company. The Company's backlog of unshipped orders was $110,359,000 and $83,856,000 at February 1, 2003, and March 1, 2002, respectively. At February 1, 2003, the Company had 1,897 full-time employees. None of the Company's employees are represented by a labor union or other collective bargaining representative. The Company believes that its relations with its employees are good. ITEM 2. PROPERTIES. The Company operates out of four office/manufacturing facilities in Zeeland, Michigan, approximately 25 miles southwest of Grand Rapids. The office and production facility for the Fire Protection Products Group is a 25,000-square-foot, one-story building leased by the Company since 1978 from related parties (see Part III, Item 13, of this report). The corporate office and production facility for the Company's Automotive Products Group is a modern, two-story, 150,000-square-foot building of steel and masonry construction situated on a 40-acre site in a well-kept industrial park. An additional 128,000-square-foot office/manufacturing facility on this site was opened during 1996. The Company expanded its automotive production facilities by constructing a third 170,000 square-foot facility on its current site which opened in the second quarter of 2000. In November 2002, the Company announced plans to expand its manufacturing operations in Zeeland, Michigan, with the construction of another automotive mirror manufacturing facility which is scheduled to open in 2005. The Company plans to invest approximately $100 million over a 5-year period for land, the facility and manufacturing equipment to meet the Company's future automotive production needs. The Company also plans to construct a 40,000 square-foot office, distribution and light manufacturing facility near Neckarsulm, Germany, at a cost of approximately $4-5 million, which is scheduled to be completed by the end of 2003.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION. CRITICAL ACCOUNTING POLICIES. The Company's significant accounting policies are described in Note 1 to the consolidated financial statements. The policies described below represent those that are broadly applicable to its operations and involve additional management judgment due to the sensitivity of the methods, assumptions and estimates necessary in determining the related amounts. Revenue Recognition. The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, as amended. Accordingly, revenue is recognized based on the terms of the customer purchase order that indicates title to the product and risk of ownership passes to the customer upon shipment. Sales are shown net of returns, which have not historically been significant. The Company does not generate sales from sale arrangements with multiple deliverables. Inventories. Estimated inventory allowances for slow-moving and obsolete inventories are based on current assessments of future demands, market conditions and related management initiatives. If market conditions or customer requirements change and are less favorable than those projected by management, inventory allowances are adjusted accordingly. Investments. The Company's investment committee regularly reviews its fixed income and equity investment portfolio for any unrealized losses that would be deemed other-than-temporary and require the recognition of an impairment loss in income. Management uses criteria such as the period of time that securities have been in an unrealized loss position, types of securities and their related industries, as well as published investment ratings and analyst reports to evaluate their portfolio. Management considers the unrealized losses at December 31, 2002, to be temporary in nature. Self Insurance. The Company is self-insured for health and workers' compensation benefits up to certain stop-loss limits. Such costs are accrued based on known claims and an estimate of incurred, but not reported (IBNR) claims. IBNR claims are estimated using historical lag information and other data provided by claims administrators. This estimation process is subjective, and to the extent that future actual results differ from original estimates, adjustments to recorded accruals may be necessary. RESULTS OF OPERATIONS The following table sets forth for the periods indicated certain items from the Company's Consolidated Statements of Income expressed as a percentage of net sales and the percentage change in the dollar amount of each such item from that in the indicated previous year.

RESULTS OF OPERATIONS: 2002 TO 2001 Net Sales. Automotive net sales increased by 29% on a 23% increase in mirror shipments, from 7,180,000 to 8,806,000 units, primarily reflecting increased penetration on 2002 and 2003 model year vehicles for interior electrochromic Night Vision Safety Mirrors and higher dollar content on certain 2003 model year vehicles. North American unit shipments increased by 19%, while overseas unit shipments increased by 28% during 2002. Net sales of the Company's fire protection products increased 1%, as shipments continued to be impacted by the reduced demand in the hotel construction industry after the September 11, 2001, terrorist attacks. Cost of Goods Sold. As a percentage of net sales, cost of goods sold decreased from 61% to 60%, primarily reflecting fixed manufacturing overhead expenses being spread over increased sales volume, product mix, and purchasing cost reductions, partially offset by automotive customer price reductions. Operating Expenses. Engineering, research and development expenses increased approximately $2,288,000, but decreased from 7% to 6% of net sales, primarily due to additional staffing for new electronic product development, including SmartBeam and telematics. Selling, general and administrative expenses increased approximately $2,215,000, but decreased from 6% to 5% of net sales, primarily reflecting the expansion of the Company's overseas sales offices to support the Company's current and future overseas sales growth. Other Income - Net. Investment income decreased $1,527,000 in 2002, primarily due to significantly lower interest rates. Other income decreased $1,159,000 in 2002, primarily due to realized equity investment losses in 2002 compared to realized equity investment gains in 2001. Taxes. The provision for federal income taxes varied from the statutory rate in 2002 primarily due to exempted taxable income under the Extraterritorial Income Exclusion Act from increased foreign sales, and tax-exempt interest income. Net Income. Net income increased by 32%, primarily reflecting the higher sales volume and improved gross margin, partially offset by higher operating expenses, in 2002 as compared to 2001. RESULTS OF OPERATIONS: 2001 TO 2000 Net Sales. Automotive net sales increased by 5% and mirror shipments increased by 6%, from 6,757,000 to 7,180,000 units, primarily reflecting increased penetration on foreign 2001 and 2002 model year vehicles for interior electrochromic NVS Mirrors. North American unit shipments decreased by 2%, primarily due to the 10% decline in light vehicle industry production levels, while overseas unit shipments increased by 21% during 2001. Net sales of the Company's fire protection products decreased 3%, primarily due to the construction industry slowdown after the September 11, 2001, terrorist attacks. Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 58% to 61%, primarily reflecting automotive customer price reductions, product mix, and the temporary excess plant capacity primarily associated with the Company's third automotive mirror manufacturing facility expansion in 2000, partially offset by engineering and purchasing cost reductions. Operating Expenses. Engineering, research and development expenses increased approximately $3,784,000, and increased from 6% to 7% of net sales, primarily due to additional staffing for new electronic product development, including telematics and SmartBeam. Selling, general and administrative expenses increased approximately $1,618,000, but remained unchanged at 6% of net sales, primarily reflecting the expansion of the Company's overseas sales offices to support the Company's current and future overseas sales growth. Other Income - Net. Investment income decreased $75,000 in 2001, primarily due to significantly lower interest rates, mostly offset by higher investable balances. Other income increased $521,000 in 2001, primarily due to realized equity gains in 2001 compared to realized equity losses in 2000. -13-

Taxes. The provision for federal income taxes varied from the statutory rate in 2001 primarily due to Foreign Sales Corporation exempted taxable income from increased foreign sales, and tax-exempt interest income. Net Income. Net income decreased by 8%, primarily reflecting the reduced gross margin and increased research and development expenses in 2001. LIQUIDITY AND CAPITAL RESOURCES The Company's financial condition throughout the periods presented has remained very strong. The Company's current ratio decreased from 12.4 in 2001, to 9.5 in 2002, primarily as a result of the increase in accrued liabilities. Cash flow from operating activities for the year ended December 31, 2002, increased $33,758,000 to $119,111,000, compared to $85,353,000 for the same period last year, primarily due to increased net income. Capital expenditures for the year ended December 31, 2002, were $32,561,000, compared to $45,298,000 for the same period last year. Management considers the Company's working capital of approximately $247,738,000 and long-term investments of approximately $203,359,000 at December 31, 2002, together with internally generated cash flow and an unsecured $5,000,000 line of credit from a bank, to be sufficient to cover anticipated cash needs for the foreseeable future. On October 8, 2002, the Company announced a share repurchase plan, under which the Company may purchase up to 4,000,000 shares based on a number of factors, including market conditions, the market price of the Company's common stock, anti-dilutive effect on earnings, available cash and other factors as the Company deems appropriate. As of December 31, 2002, the Company had not purchased any shares. INFLATION, CHANGING PRICES AND OTHER In addition to price reductions over the life of its long-term agreements, the Company continues to experience pricing pressures from its automotive customers, which have affected, and which will continue to affect, its margins to the extent that the Company is unable to offset the price reductions with productivity and yield improvements, engineering and purchasing cost reductions, and increases in sales volume. In addition, profit pressures at certain automakers are resulting in increased cost reduction efforts by them, including requests for additional price reductions, decontenting certain features from vehicles, and warranty cost-sharing programs, which could adversely impact the Company's sales growth and margins. The Company also continues to experience some pressure for raw material cost increases. The Company generally supplies NVS(R) Mirrors to its customers worldwide under annual blanket purchase orders. The Company currently supplies NVS(R) Mirrors to DaimlerChrysler AG (North America) and General Motors Corporation under long-term agreements. The long-term supply agreement with DaimlerChrysler AG runs through the 2003 Model Year, and the GM contract runs through the 2004 Model Year for inside mirrors. Automakers have been experiencing increased volatility and uncertainty in executing planned new programs which have, in some cases, resulted in cancellations or delays of new vehicle platforms, package reconfigurations and inaccurate volume forecasts. This increased volatility and uncertainty has made it more difficult for the Company to forecast future sales and effectively utilize capital, engineering, research and development, and human resource investments. The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its consolidated financial statements. -14-

MARKET RISK DISCLOSURE The Company is subject to market risk exposures of varying correlations and volatilities, including foreign exchange rate risk, interest rate risk and equity price risk. The Company has some assets, liabilities and operations outside the United States, which currently are not significant. Because the Company sells its automotive mirrors throughout the world, it could be significantly affected by weak economic conditions in foreign markets that could reduce demand for its products. Nearly all of the Company's non-U.S. sales are invoiced and paid in U.S. dollars; during 2002, approximately 3% of the Company's net sales were invoiced and paid in European euros. The Company currently expects that approximately 5% of the Company's net sales in 2003 will be invoiced and paid in European euros. The Company does not currently engage in hedging activities. The Company manages interest rate risk and default risk in its fixed-income investment portfolio by investing in shorter-term maturities and investment grade issues. The Company's fixed-income investments' maturities at carrying value ($000,000), which closely approximates fair value, and average interest rates are as follows: Total Balance 2007 - as of December 31, 2003 2004 2005 2006 2008 2002 2001 ------------------------------------------------------ ---------------------------- U.S. Treasuries Amount $22.5 $15.3 - - - $37.8 $72.2 Average Interest Rate 6% 3% 4% 6% Municipal Amount $5.7 $18.9 $9.0 $0.5 - $34.1 $27.0 Average Interest Rate* 3% 2% 3% 4% 3% 3% Certificates of Deposit Amount $11.1 $20.3 $5.3 $27.3 - $64.0 $20.5 Average Interest Rate 6% 4% 5% 4% 5% 6% Corporate Amount $5.4 $27.4 $5.1 - $0.3 $38.2 $11.8 Average Interest Rate 7% 5% 7% 7% 6% 7% Other Amount $2.1 - - - - $2.1 $2.1 Average Interest Rate 4% 4% 6% *After-tax Most of the Company's equity investments are managed by a number of outside equity fund managers who invest primarily in large capitalization companies trading on the U.S. stock markets.

REPORT OF INDEPENDENT AUDITORS To the Board of Directors and Shareholders of Gentex Corporation: We have audited the accompanying consolidated balance sheets of Gentex Corporation and subsidiaries as of December 31, 2002 and 2001, and the related consolidated statements of income, shareholders' investment and cash flows for each of the three years in the period ended December 31, 2002. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1) SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES The Company Gentex Corporation designs, develops, manufactures and markets proprietary electro-optical products: automatic rearview mirrors for the automotive industry and fire protection products for the commercial building industry. A substantial portion of the Company's net sales and accounts receivable result from transactions with domestic and foreign automotive manufacturers and tier one suppliers. The Company's fire protection products are primarily sold to domestic distributors and original equipment manufacturers of fire and security systems. The Company does not require collateral or other security in trade accounts receivable. Significant accounting policies of the Company not described elsewhere are as follows: Consolidation The consolidated financial statements include the accounts of Gentex Corporation and all of its wholly-owned subsidiaries (together the "Company"). All significant intercompany accounts and transactions have been eliminated. Cash Equivalents Cash equivalents consist of funds invested in money market accounts. Investments Equity securities and U.S. Treasuries are available for sale and are stated at fair value based on quoted market prices. Adjustments to the fair value of available for sale investments are recorded as increases or decreases, net of income taxes, within accumulated other comprehensive income (loss) in shareholders' investment. Fixed income securities, excluding U.S. Treasuries, are considered held to maturity and, accordingly, are carried at amortized cost. The amortized cost, unrealized gains and losses, and market value of securities held to maturity and available for sale are shown as of December 31, 2002 and 2001: Unrealized ----------------------------------- 2002 Cost Gains Losses Market Value --------------------------------------------------------------------------------------------------------- U.S. Treasuries $ 36,886,208 $ 951,293 - $ 37,837,501 Municipal Bonds 34,083,850 627,632 (6,596) 34,704,886 Certificates of Deposit 64,035,770 - - 64,035,770 Corporate Bonds 38,216,594 862,248 (36,613) 39,042,229 Other Fixed Income 2,050,126 - - 2,050,126 Equity 84,274,542 1,738,031 (12,060,791) 73,951,782 ---------- --------- ------------ ---------- $259,547,090 $4,179,204 $(12,104,000) $251,622,294 ============ ========== ============= ============ 2001 U.S. Treasuries $ 69,991,935 $2,172,456 $ - $ 72,164,391 Municipal Bonds 27,008,487 227,952 (42,554) 27,193,885 Certificates of Deposit 20,491,262 - - 20,491,262 Corporate Bonds 11,837,566 506,260 (7,375) 12,336,451 Other Fixed Income 2,099,158 - - 2,099,158 Equity 61,306,343 5,345,938 (1,622,895) 65,029,386 ------------- ----------- ----------- ------------- $192,734,751 $8,252,606 $ (1,672,824) $199,314,533 ============ ========== ============ ============ Fixed income securities as of December 31, 2002, have contractual maturities as follows: Held to Maturity U.S. Treasuries ---------------- --------------- Due within one year $ 24,266,690 $21,905,421 Due between one and five years 113,827,320 14,980,787 Due over five years 292,330 - ------------ ----------- $138,386,340 $36,886,208 ============ =========== During 2000, the Company sold approximately $947,000 of securities classified as held to maturity for $952,000.

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (1) SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES, continued Inventories Inventories include material, direct labor and manufacturing overhead and are valued at the lower of first-in, first-out (FIFO) cost or market. Inventories consisted of the following as of December 31, 2002 and 2001: 2002 2001 ---- ---- Raw materials $ 9,911,022 $ 8,376,321 Work-in-process 1,744,372 1,649,389 Finished goods 6,086,615 4,379,640 ----------- ----------- $17,742,009 $14,405,350 =========== =========== Plant and Equipment Plant and equipment are stated at cost. Depreciation and amortization are computed for financial reporting purposes using the straight-line method, with estimated useful lives of 7 to 40 years for buildings and improvements, and 3 to 10 years for machinery and equipment. Patents The Company's policy is to capitalize costs incurred to obtain patents. The cost of patents is amortized over their useful lives. The cost of patents in process is not amortized until issuance. Accumulated amortization was approximately $2,726,000 and $2,333,000 at December 31, 2002 and 2001, respectively. At December 31, 2002, patents have a weighted average amortization life of 12 years. Patent amortization expense was approximately $393,000, $238,000 and $355,000, in 2002, 2001, and 2000, respectively. For each of the next five years, patent amortization expense will approximate $150,000 annually. Revenue Recognition The Company's revenue is generated primarily from sales of its products. Sales are recognized when the product is shipped and legal title has passed to the customer. Advertising and Promotional Materials All advertising and promotional costs are expensed as incurred and amounted to approximately $904,000, $653,000 and $932,000, in 2002, 2001, and 2000, respectively. Repairs and Maintenance Major renewals and improvements of property and equipment are capitalized, and repairs and maintenance are expensed as incurred. The Company incurred expenses relating to the repair and maintenance of plant and equipment of approximately $3,761,000, $3,780,000, and $3,182,000, in 2002, 2001, and 2000, respectively. Self-Insurance The Company is self-insured for a portion of its risk on workers' compensation and employee medical costs. The arrangements provide for stop loss insurance to manage the Company's risk. Operations are charged with the cost of claims reported and an estimate of claims incurred but not reported. Product Warranty The Company periodically incurs product warranty costs. Any liabilities associated with product warranty are estimated based on known facts and circumstances and are not significant at December 31, 2002 and 2001. The Company does not offer extended warranties on its products. -27-

Other Comprehensive Income (Loss) Comprehensive income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. For the Company, comprehensive income represents net income adjusted for unrealized gains and losses on certain investments and foreign currency translation adjustments. The changes in the components of other comprehensive income (loss) are as follows: Years Ended December 31, -------------------------------------------------------------------------------------------- 2002 2001 2000 --------------------------- -------------------------- ---------------------- Pre-Tax Tax Exp.

Assets and liabilities are translated at the exchange rate in effect at year-end. Income statement accounts are translated at the average rate of exchange in effect during the year. The resulting translation adjustment is recorded as a separate component of shareholders' investment. Gains and losses arising from re-measuring foreign currency transactions into the appropriate currency are included in the determination of net income. Stock-Based Compensation Plans At December 31, 2002, the Company has two stock option plans and an employee stock purchase plan, which are described more fully in Note 6. The Company accounts for these plans under the recognition and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. No stock-based employee compensation cost is reflected in net income for these plans, as all options granted under these plans have an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation," to stock-based employee compensation. -28-

The fair value of each option grant in the Nonemployee Director Stock Option Plans was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions used for grants in 2002, 2001, and 2000, respectively: risk-free interest rates of 4.0, 5.1, and 5.0 percent; expected dividend yields of 0.0, 0.0, and 0.0 percent; expected lives of 9, 9, and 9 years; expected volatility of 53, 54, and 54 percent. Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts 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 reporting period. Actual results could differ from those estimates. Reclassification Certain prior year amounts have been reclassified to conform with the current year presentation. New Accounting Standards In December 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure - an amendment of FASB Statement No. 123," which amends SFAS No. 123 to provide alternative methods of transition for a voluntary change to the fair-value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require disclosure in interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The Company does not intend to adopt a fair-value based method of accounting for stock-based employee compensation until a final standard is issued by the FASB that addresses industry concerns related to applicability of current option pricing models to non-exchange traded employee option plans. In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." Interpretation No. 45 changes current practice in accounting for and disclosure of guarantees and will require certain guarantees to be recorded as liabilities at fair value on the balance sheet. Current practice requires that liabilities related to guarantees be recorded only when a loss is probable and reasonably estimable, as those terms are defined in SFAS No. 5, "Accounting for Contingencies." Interpretation No. 45 also requires a guarantor to make significant new disclosures, even when the likelihood of making any payments under the guarantee is remote. The disclosure requirements of Interpretation No. 45 are effective immediately. The initial recognition and measurement provisions are applicable on a prospective basis to guarantees issued or modified after December 31, 2002. The Company is not aware of any significant guarantees that would require current disclosure or further recognition under Interpretation No. 45. -29-

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (2) LINE OF CREDIT The Company has available an unsecured $5,000,000 line of credit from a bank at an interest rate equal to the lower of the bank's prime rate or 1.5% above the LIBOR rate. No borrowings were outstanding under this line in 2002 or 2001. No compensating balances are required under this line. (3) INCOME TAXES The provision for income taxes is based on the earnings reported in the accompanying consolidated financial statements. The Company recognizes deferred income tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. Under this method, deferred income tax liabilities and assets are determined based on the cumulative temporary differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred income tax expense is measured by the net change in deferred income tax assets and liabilities during the year. The components of the provision for income taxes are as follows: 2002 2001 2000 ----------- ----------- ----------- Currently payable: Federal $37,188,500 $30,084,000 $33,417,000 State 321,000 104,000 65,000 Foreign 91,000 177,000 - ----------- ----------- ----------- Total 37,600,500 30,365,000 33,482,000 ----------- ----------- ----------- Net deferred: Primarily federal 3,701,000 1,036,000 497,000 ----------- ----------- ----------- Provision for income taxes $41,301,500 $31,401,000 $33,979,000 =========== =========== =========== The currently payable provision is further reduced by the tax benefits associated with the exercise, vesting or disposition of stock under the stock plans described in Note 6. These reductions totaled approximately $5,093,000, $3,929,000, and $4,878,000, in 2002, 2001, and 2000, respectively, and were recognized as an adjustment of additional paid-in capital. The effective income tax rates are different from the statutory federal income tax rates for the following reasons: 2002 2001 2000 ---- ---- ---- Statutory federal income tax rate 35.0% 35.0% 35.0% State income taxes, net of federal income tax benefit 0.2 0.1 0.1 Foreign source exempted income (2.4) (2.2) (2.0) Tax-exempt investment income (0.2) (0.3) (0.4) Other (0.1) (0.1) (0.2) ---- ---- ---- Effective income tax rate 32.5% 32.5% 32.5% ==== ==== ==== The tax effect of temporary differences which give rise to deferred income tax assets and liabilities at December 31, 2002 and 2001, are as follows: 2002 2001 ----------------------------- ------------------------------- Current Non-Current Current Non-Current Assets: Accruals not currently deductible $1,462,530 $ 274,803 $ 1,073,408 $ 274,803 Deferred compensation - 842,053 - 817,110 Unrealized loss on investments - 3,280,013 - - Other 2,152,859 5,960 1,098,961 7,920 ---------- ----------- ----------- ----------- Total deferred income tax assets 3,615,389 4,402,829 2,172,369 1,099,833 Liabilities: Excess tax over book depreciation - (10,317,831) - (5,418,282) Patent costs - (557,268) - (454,992) Unrealized gain on investments - - - (2,063,424) Other (423,568) - (257,916) - ---------- ----------- ----------- ----------- Net deferred incomes taxes $3,191,821 $(6,472,270) $ 1,914,453 $(6,836,865) ========== =========== =========== =========== Income taxes paid in cash were approximately $30,828,000, $26,546,000, and $28,302,000, in 2002, 2001, and 2000, respectively. -30-

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (4) EMPLOYEE BENEFIT PLAN The Company has a 401(k) retirement savings plan in which substantially all of its employees may participate. The plan includes a provision for the Company to match a percentage of the employee's contributions at a rate determined by the Company's Board of Directors. In 2002, 2001, and 2000, the Company's contributions were approximately $955,000, $718,000, and $620,000, respectively. The Company does not provide health care benefits to retired employees. (5) SHAREHOLDER PROTECTION RIGHTS PLAN The Company has a Shareholder Protection Rights Plan (the Plan). The Plan is designed to protect shareholders against unsolicited attempts to acquire control of the Company in a manner that does not offer a fair price to all shareholders. Under the Plan, one purchase Right automatically trades with each share of the Company's common stock. Each Right entitles a shareholder to purchase 1/100 of a share of junior participating preferred stock at a price of $110, if any person or group attempts certain hostile takeover tactics toward the Company. Under certain hostile takeover circumstances, each Right may entitle the holder to purchase the Company's common stock at one-half its market value or to purchase the securities of any acquiring entity at one-half their market value. Rights are subject to redemption by the Company at $.005 per Right and, unless earlier redeemed, will expire on March 29, 2011. Rights beneficially owned by holders of 15 percent or more of the Company's common stock, or their transferees, automatically become void. (6) STOCK-BASED COMPENSATION PLANS The Company may sell up to 1,600,000 shares of stock to its employees under its Employee Stock Purchase Plan. The Company has sold to employees 44,009 shares, 45,463 shares, and 47,023 shares in 2002, 2001, and 2000, respectively, and has sold a total of 561,187 shares through December 31, 2002. The Company sells shares at 85% of the stock's market price at date of purchase. The weighted average fair value of shares sold in 2002, 2001, and 2000, was approximately $24.86, $20.75, and $22.00, respectively. The Company may grant options for up to 9,000,000 shares under its Employee Stock Option Plan. The Company has granted options on 7,618,898 shares through December 31, 2002. Under the Plan, the option exercise price equals the stock's market price on date of grant. The options vest after one to five years, and expire after two to seven years. A summary of the status of the Company's employee stock option plan at December 31, 2002, 2001, and 2000, and changes during the years then ended is presented in the table and narrative below: 2002 2001 2000 ------------------- ------------------- ------------------- Shares Wtd.

Under the director plans, the option exercise price equals the stock's market price on date of grant. The Director Plan options vest after six months, and all expire after ten years.

Shares awarded under the plans entitle the shareholder to all rights of common stock ownership except that the shares may not be sold, transferred, pledged, exchanged or otherwise disposed of during the restriction period. The restriction period is determined by a committee, appointed by the Board of Directors, but may not exceed ten years. During 2002, 2001, and 2000, 37,900, 57,800, and 47,800 shares, respectively, were granted with restriction periods of four to six years at market prices ranging from $27.47 to $32.30 in 2002, $23.59 to $26.97 in 2001, and $18.75 to $37.625 in 2000. The related expense is reflected as a deferred compensation component of shareholders' investment in the accompanying consolidated financial statements and is being amortized over the applicable restriction periods. -32-

In the opinion of management, the amount of ultimate liability with respect to these actions will not materially affect the financial position or future results of operations of the Company. (8) SEGMENT REPORTING SFAS No. 131, "Disclosures About Segments of an Enterprise and Related Information" requires that a public enterprise report financial and descriptive information about its reportable operating segments subject to certain aggregation criteria and quantitative thresholds. Operating segments are defined by SFAS No. 131 as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-makers in deciding how to allocate resources and in assessing performance. 2002 2001 2000 ------------ ------------ ------------ Revenue: Automotive Products U.S. $203,691,964 $153,685,309 $154,972,098 Germany 70,710,037 63,245,473 60,754,241 Japan 44,797,340 23,823,498 18,545,538 Other 55,050,622 48,669,920 41,582,257 Fire Protection Products 21,008,473 20,880,796 21,566,668 ------------ ------------ ------------ Total $395,258,436 $310,304,996 $297,420,802 ============ ============ ============ Income from Operations: Automotive Products $111,448,849 $ 78,041,939 $ 86,218,950 Fire Protection Products 3,751,312 4,017,303 4,192,041 ------------ ------------ ------------ Total $115,200,161 $ 82,059,242 $ 90,410,991 ============ ============ ============ Assets: Automotive Products $154,685,204 $144,204,490 $119,720,400 Fire Protection Products 4,035,944 3,779,501 4,396,643 Other 450,451,519 358,838,807 304,011,650 ------------ ------------ ------------ Total $609,172,667 $506,822,798 $428,128,693 ============ ============ ============ Automotive Products $16,930,161 $ 13,699,709 $ 10,349,325 Fire Protection Products 260,823 294,956 315,018 Other 1,440,616 1,198,153 669,761 ------------ ------------ ------------ Total $18,631,600 $ 15,192,818 $ 11,334,104 Capital Expenditures: Automotive Products $19,236,000 $ 39,383,150 $ 21,084,629 Fire Protection Products 442,593 280,251 192,222 Other 12,882,053 5,635,028 340,237 ------------ ------------ ------------ Total $32,560,646 $ 45,298,429 $ 21,617,088 ============ ============ ============ -33-

SECTION 2. REPLACEMENT OF LOST OR DESTROYED CERTIFICATES. In the event of the loss or destruction of a stock certificate, no new certificate shall be issued in place thereof until the Corporation has received from the registered holder such assurances, representations, warranties and/or guarantees as the Board of Directors, in its sole discretion, shall deem advisable, and until the Corporation receives such indemnification protecting it against any claim that may be made on account of such lost or destroyed certificate, or the issuance of any new certificate in place thereof, including an indemnity bond in such amount and with sureties, if any, as the Board of Directors, in its sole discretion, deems advisable. SECTION 3. TRANSFER OF SHARES. Shares of stock of the Corporation shall be transferable only upon the books of the Corporation.

SECTION 4. RULES GOVERNING STOCK CERTIFICATES. The Board of Directors shall have the power and authority to make all such rules and regulations as they may deem expedient concerning the issue, transfer and registration of certificates of stock, and may appoint a transfer agent and a registrar of transfer, and may require all such certificates to bear the signature of such transfer agent and of such registrar of transfers.

The Board of Directors may fix a date not exceeding sixty (60) days preceding the date of payment of any dividend, or the date for the allotment of rights, or the date when any change or conversion or exchange of capital stock shall go into effect, as a record date for the determination of the shareholders entitled to receive payment of any such dividends, or any such allotment of rights, or to exercise the rights with respect to any such change, conversion, or exchange of capital stock; provided, however, that such date shall not precede the date on which the Board takes action to establish the record date. Only shareholders of record on the date so fixed shall be entitled to receive payment of such dividends, or allotment of rights, or exercise such rights, as the case may be, notwithstanding any transfer of any stock on the books of the Corporation after any such record date is fixed. -36-

SECTION 6. DIVIDENDS. The Board of Directors, in its discretion, may from time to time declare and make a distribution to shareholders in respect of the Corporation's outstanding shares, payable in cash, the Corporation's indebtedness (but not the Corporation's shares) or the Corporation's other property, including the shares or indebtedness of other corporations; provided, however, no such distribution shall be made if, after giving effect to the distribution, the Corporation would not be able to pay its debts as they become due in the usual course of business, or the Corporation's total assets would be less than its total liabilities plus the amount that would be needed if the Corporation were to be dissolved at the time of the distribution to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution. In addition, the Board of Directors, in its discretion, from time to time may declare and direct the payment of a share dividend of the Corporation's shares, issued pro rata and without consideration, to the Corporation's shareholders or to the shareholders of one or more classes or series; provided, however, shares of one class or series may not be issued as a share dividend in respect of shares of another class or series unless the Articles of Incorporation so authorize, a majority of the votes entitled to be cast by the class or series to be issued approve the issue, or there are no outstanding shares of the class or series to be issued. SECTION 7. TREASURY SHARES. Shares that have been issued and reacquired by the Corporation shall constitute authorized but unissued shares. SECTION 8. REDEMPTION OF CONTROL SHARES. Control shares acquired in a control share acquisition, with respect to which no acquiring person statement has been filed with the Corporation, shall, at any time during the period ending sixty (60) days after the last acquisition of control shares or the power to direct the exercise of voting power of control shares by the acquiring person, be subject to redemption by the Corporation. After an acquiring person statement has been filed with the Corporation and after the meeting at which the voting rights of the control shares acquired in a control share acquisition are submitted to the shareholders, the shares shall be subject to redemption by the Corporation unless the shares are accorded full voting rights by the shareholders as provided in Section 798 of the Michigan Business Corporation Act. Redemptions of shares pursuant to this bylaw shall be at the fair value of the shares pursuant to procedures adopted by the Board of Directors of the Corporation.

SECTION 4. RECORD DATE FOR NOTICE AND VOTE. The Board of Directors may fix a date not more than sixty (60) nor less than ten (10) days before the date of a shareholders' meeting as the record date for the purpose of determining shareholders entitled to notice of and to vote at the meeting or adjournments thereof; provided, however, that such date shall not precede the date on which the Board takes action to establish the record date.

SECTION 5. NOTICE OF SHAREHOLDER MEETINGS. Written notice of the time, place, and purposes of any meeting of shareholders shall be given to shareholders entitled to vote thereat, not less than ten (10) nor more than sixty (60) days before the date of the meeting, which notice may be given either by delivery in person to such shareholders or by mailing such notice to shareholders at their addresses as the same appear on the stock books of the Corporation. A shareholder's attendance at a meeting will result in a waiver of objection to lack of notice or defective notice unless the shareholder, at the beginning of the meeting, objects to the holding of the meeting or the transaction of business at the meeting, and a waiver of objection to consideration of a particular matter at the meeting as not being within the purpose or purposes described in the meeting notice unless the shareholder objects to considering the matter when it is presented. -37-

The Corporation's officer or agent having charge of its stock transfer books shall prepare and certify a complete list of the shareholders entitled to vote at a shareholders' meeting or any adjournment thereof, which list shall be arranged alphabetically within each class and series, and shall show the address of and number of shares held by each shareholder. The list shall be produced at the time and place of the meeting of shareholders and be subject to inspection by any shareholder at any time during the meeting. If for any reason these requirements with respect to this shareholder list have not been complied with, any shareholder, either in person or by proxy, who in good faith challenges the existence of sufficient votes to carry any action at the meeting, may demand that the meeting be adjourned and the same shall be adjourned until the requirements are complied with; provided, however, that failure to comply with such requirements does not affect the validity of any action taken at the meeting before such demand is made. SECTION 7. VOTING. Each shareholder entitled to vote at a meeting of shareholders or to express consent or dissent without a meeting, shall be entitled to one (1) vote, in person or by proxy, for each share entitled to vote that is held by such shareholder; provided, however, no proxy shall be voted after three years from its date unless such proxy expressly provides for a longer period. A vote may be cast either orally or in writing as announced or directed by the person presiding at the meeting prior to the taking of the vote. When an action other than the election of directors is to be taken by vote of the shareholders, it shall be authorized by a majority of the votes cast by the holders of shares entitled to vote on the action, unless a greater vote is required by the Michigan Business Corporation Act. Directors shall be elected by a plurality of the votes cast in an election. SECTION 8. QUORUM. Shares equaling a majority of all of the voting shares of the capital stock of the Corporation issued and outstanding, represented in person or by proxy, shall constitute a quorum at meetings of shareholders. Meetings at which less than a quorum is represented may be adjourned by a vote of a majority of the shares present to a further date without further notice other than the announcement at such meeting, and when the quorum shall be present upon such adjourned date, any business may be transacted which might have been transacted at the meeting as originally called. Shareholders present in person or by proxy at any meeting of shareholders may continue to do business until adjournment, notwithstanding the withdrawal of shareholders to leave less than a quorum. SECTION 9. CONDUCT OF MEETINGS. The officer who is to preside at meetings of shareholders pursuant to Article V of these Bylaws, or his or her designee, shall determine the agenda, the order in which business shall be conducted and rules for the conduct of the meeting (which shall be fair to shareholders), unless the agenda, the order of business and/or such rules have been fixed by the Board of Directors. Such officer or designee shall call meetings of shareholders to order and shall preside, shall appoint a person to act as secretary of the meeting, and may appoint a parliamentarian, who may be the same person as the secretary. SECTION 10. INSPECTORS OF ELECTIONS. The Board of Directors may, in advance of a meeting of shareholders, appoint one or more inspectors to act at the meeting or any adjournment thereof. In the event inspectors are not so appointed, or an appointed inspector fails to appear or act, the person presiding at the meeting of shareholders may appoint one or more persons to fill such vacancy or vacancies, or to act as inspector. The inspector(s) shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots, or consents, hear and determine challenges and questions arising in connection with the right to vote, count and tabulate votes, ballots or consents, determine the results, and do such acts as are proper to conduct the election or vote with fairness to all shareholders. SECTION 11. NOTICE OF SHAREHOLDER PROPOSALS. (a) Except for the election of directors, which is governed by Article VI of the Corporation's Articles of Incorporation, only such business shall be conducted at any meeting of shareholders, and only such proposals shall be acted upon at such meetings, as shall have been brought before the meeting: (i) by, or at the direction of the Board of Directors; or (ii) by any shareholder of the Corporation who complies with the notice procedures set forth in this Section of these Bylaws. For a proposal to be properly brought before the meeting by a shareholder, the shareholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a shareholder's notice must be delivered to, or mailed and received at, the principal executive offices of the Corporation not less than sixty (60) days nor more than ninety (90) days prior to the scheduled meeting date, regardless of any postponements, deferrals, or adjournments of that meeting to any later date; provided, however, that if less than seventy (70) days' notice, or prior public disclosure of the date of a scheduled meeting is given or made, notice by the shareholder to be timely must be delivered or received not later than the close of business on the tenth (10th) day following the earlier of the day on which such notice of the date of the scheduled meeting was mailed or the day on which such public disclosure was made. A shareholder's notice to the Secretary shall set forth, as to each matter the shareholder proposes to bring before the meeting: (i) a brief description of a proposal desired to be brought before the meeting and the reasons for conducting such business at the meeting; (ii) the name and address, as they appear on the Corporation's stock record, of the shareholder proposing such business and any other shareholders known by such shareholder to be supporting such proposal; (iii) the class and number of shares of the Corporation's stock which are beneficially owned by the shareholder on the date of such shareholder notice and by any other shareholders known by such -38-

shareholder to be supporting such proposal on the date of such shareholder notice; and (iv) any financial interest of the shareholder in such proposal. (b) If the presiding officer at the meeting of shareholders determines that a shareholder proposal was not made in accordance with the terms of this Section, the presiding officer shall declare the matter to be out of order and the matter shall not be acted upon at the meeting. (c) Nothing contained in this Section shall prevent the consideration and approval or disapproval at any meeting of shareholders of reports of officers, directors, and committees of the Board of Directors, but, in connection with such reports, no business shall be acted upon at such meeting unless stated, filed, and received as provided herein.
