GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (1) The unaudited condensed consolidated financial statements included herein have been prepared by the Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although the Registrant believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these unaudited condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Registrant's 2007 annual report on Form 10-K. (2) In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only a normal and recurring nature, necessary to present fairly the financial position of the Registrant as of September 30, 2008, and the results of operations and cash flows for the interim periods presented. (3) Adoption of New Accounting Standards In June 2008, the Financial Accounting Standards Board (FASB) issued FSP No. EITF 03-6-1, "Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities," (FSP EITF 03-6-1). FSP EITF 03-6-1 states that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two class method. FSP EITF 03-6-1 becomes effective on January 1, 2009. The Company has concluded that the adoption of FSP EITF 03-6-1 will not have a material impact on its consolidated financial position or results of operations. In September 2006, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements" ("SFAS No. 157"). This statement establishes a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases require, estimates of fair market value. SFAS No. 157 also expands financial statement disclosure requirements about a company's use of fair value measurements, including the effect of such measure on earnings. SFAS No. 157 was effective for fiscal years beginning after November 15, 2007. The Company adopted the provisions of SFAS No. 157 related to its financial assets and liabilities in the first quarter of 2008, which did not have a material impact on the Company's consolidated financial position, results of operations or cash flows. The Company's investment securities are classified as available for sale and are stated at fair value based on quoted market prices. Assets or liabilities that have recurring measurements are shown below as of September 30, 2008: Fair Value Measurements at Reporting Date Using -------------------------------------------------- Quoted Prices in Active Markets Significant Significant for Identical Other Observable Unobservable Assets Inputs Inputs ---------------- ---------------- ------------ Total as of Description September 30, 2008 (Level 1) (Level 2) (Level 3) - ----------------------- ------------------ ---------------- ---------------- ------------ Cash & Cash Equivalents $283,333,742 $283,333,742 $ -- $ -- Short-Term Investments 54,913,589 19,913,589 35,000,000 -- Long-Term Investments 106,621,165 106,621,165 -- -- ------------ ------------ ----------- ---- Net $444,868,496 $409,868,496 $35,000,000 $ -- -5-

Readers should refer to Note 6 of our consolidated financial statements in our Annual Report on Form 10-K for the calendar year ended December 31, 2007, for additional information related to these stock-based compensation plans. The Company recognized compensation expense for share-based payments of $2,135,781 and $6,200,322 for the third quarter and nine months ended September 30, 2008, respectively. Compensation cost capitalized as part of inventory as of September 30, 2008, was $96,721. -6-

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED (UNAUDITED) (6) Stock-Based Compensation Plans (continued) Employee Stock Option Plan The fair value of each option grant in the Employee Stock Option Plan was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for the indicated periods: Three Months Ended Nine Months Ended September 30, September 30, ------------------ ----------------- 2008 2007 2008 2007 ------ ------ ------ ------ Dividend yield 2.15% 2.00% 2.09% 1.99% Expected volatility 31.57% 29.80% 30.89% 29.40% Risk-free interest rate 2.98% 4.26% 2.94% 4.57% Expected term of options (in years) 4.31 4.31 4.31 4.32 Weighted-average grant-date fair value $ 3.77 $ 5.39 $ 3.77 $ 4.97 The Company determined that all employee groups exhibit similar exercise and post-vesting termination behavior to determine the expected term. Under the plans, 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 five to seven years. As of September 30, 2008, there was $11,341,058 of unrecognized compensation cost related to share-based payments which is expected to be recognized over the vesting period with a weighted-average period of 4.1 years. Non-employee Director Stock Option Plan As of September 30, 2008, there was $75,101 of unrecognized compensation cost under this plan related to share-based payments which is expected to be recognized over the balance of the 2008 calendar year. Under the plan, the option exercise price equals the stock's market price on date of grant. The options vest after six months, and expire after ten years. Employee Stock Purchase Plan In 2003, a new Employee Stock Purchase Plan covering 1,200,000 shares was approved by the shareholders, replacing a prior plan. Under the plan, the Company sells shares at 85% of the stock's market price at date of purchase. Under SFAS 123(R), the 15% discounted value is recognized as compensation expense. Restricted Stock Plan In May of 2008, an amendment to the Company's Second Restricted Stock Plan was approved by the Shareholders. The plan amendment increased the maximum number of shares that may be subject to awards to 2,000,000 shares (in the aggregate) and to change the Plan's termination date from March 2, 2011, to February 21, 2018. The Company had granted 770,058 shares of restricted stock prior to the plan amendment (net of cancellations). The purpose of the Plan is to permit grants of shares, subject to restrictions, to key employees of the Company as a means of retaining and rewarding them for long-term performance and to increase their ownership in the Company. Shares awarded under the plan 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 the Compensation Committee, appointed by the Board of Directors, but may not exceed ten years. As of September 30, 2008, the Company had unearned stock-based compensation of $4,815,266 associated with these restricted stock grants. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable restriction periods. Amortization expense from restricted stock grants in the third quarter and nine months ended September 30, 2008, were $483,066 and $1,452,887, respectively. -7-

GENTEX CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED (UNAUDITED) (7) 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 items such as unrealized gains and losses on investments and foreign currency translation adjustments. Comprehensive income was as follows: September 30, 2008 September 30, 2007 ------------------ ------------------ Quarter Ended $ 5,550,210 $31,155,687 Nine Months Ended $51,081,405 $95,026,188 (8) The decrease in common stock during the nine months ended September 30, 2008, was primarily due to the repurchase of 5,923,465 shares pursuant to the Company's previously announced share repurchase plan for approximately $93,353,000, partially offset by the issuance of 1,447,281 shares of the Company's common stock under its stock-based compensation plans. The Company has also recorded a $0.105 per share cash dividend in the first and second quarters and a $0.11 per share cash dividend in the third quarter. The third quarter dividend of approximately $15,366,000, was declared on August 19, 2008, and was paid on October 17, 2008. (9) The Company currently manufactures electro-optic products, including automatic-dimming rearview mirrors for the automotive industry, and fire protection products for the commercial building industry. The Company also developed and manufactures variable dimmable windows for the aircraft industry and non-auto dimming rearview automotive mirrors with electronic features: Quarter Ended Nine Months Ended September 30, September 30, --------------------------- ---------------------------- 2008 2007 2008 2007 ------------ ------------ ------------ ------------- Revenue: Automotive Products $147,290,164 $156,528,289 $484,157,368 $ 464,827,910 Other 5,766,406 5,996,514 17,361,033 18,382,687 ------------ ------------ ------------ ------------- Total $153,056,570 $162,524,803 $501,518,401 $ 483,210,597 ============ ============ ============ ============= Income from Operations: Automotive Products $ 23,292,326 $ 33,544,456 $ 99,229,035 $ 101,538,736 Other (21,315) 1,092,663 (181,138) 3,552,659 ------------ ------------ ------------ ------------- Total $ 23,271,011 $ 34,637,119 $ 99,047,897 $105,091,395 ============ ============ ============ ============= The "Other" segment includes Fire Protection Products and Dimmable Aircraft Windows.

GENTEX CORPORATION AND SUBSIDIARIES ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. RESULTS OF OPERATIONS: THIRD QUARTER 2008 VERSUS THIRD QUARTER 2007 Net Sales. Net sales for the third quarter of 2008 decreased by approximately $9,468,000, or 6%, when compared with the third quarter last year. Net sales of the Company's automotive mirrors decreased by approximately $9,238,000, or 6%, in the third quarter of 2008, when compared with the third quarter last year, primarily due to lower light vehicle production levels in North America. Auto-dimming mirror unit shipments decreased 5% from approximately 3,706,000 in the third quarter 2007 to 3,528,000 in the current quarter. Unit shipments to customers in North America for the current quarter decreased by 27% compared with the third quarter of the prior year, primarily due to lower light vehicle production levels at the traditional Big Three automakers. Mirror unit shipments for the current quarter to automotive customers outside North America increased by 13% compared with the third quarter in 2007, primarily due to increased penetration at certain European and Asian automakers. Net sales of the Company's fire protection products decreased 7% for the current quarter versus the same quarter of last year, primarily due to a weak commercial construction market. Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 64.9% in the third quarter of 2007 to 69.5% in the third quarter of 2008. This percentage increase primarily reflected the Company's inability to leverage fixed overhead costs due to weak light vehicle production levels at our customers, annual customer price reductions, and production inefficiencies due to last-minute customer order reductions, which were partially offset by purchasing cost reductions. Each negative and positive factor is estimated to have impacted cost of goods sold as a percentage of net sales by 1-2 percentage points. Operating Expenses. Engineering, research and development (E, R & D) expenses for the current quarter decreased 1% and approximately $151,000 when compared with the same quarter last year. Excluding litigation expenses of $1,579,000 in the third quarter of 2007 (see discussion under "Trends & Developments"), E, R & D expenses increased 12% when comparing the current quarter to the same quarter last year, primarily reflecting additional staffing, engineering and testing for new product development, including mirrors with additional features, such as SmartBeam(R) and Rear Camera Display. Selling, general and administrative expenses increased 13% and approximately $1,211,000, for the current quarter, when compared with the third quarter of 2007, primarily due to the continued expansion of the Company's overseas offices and foreign exchange rates. Foreign exchange rates accounted for approximately three percentage points of the increase. Total Other Income (expense). Total other income (expense) for the current quarter decreased by approximately $9,782,000, or 106%, when compared with the third quarter of 2007, primarily due to increased realized losses on the sale of equity investments (which accounted for approximately two-thirds of the decrease) and lower interest income due to lower interest rates. Taxes. The provision for income taxes varied from the statutory rate during the current quarter, primarily due to the domestic manufacturing deduction. Net Income. Net income for the third quarter of 2008 decreased by approximately $14,680,000, or 49%, when compared with the same quarter last year, primarily due to the reduced operating margin and the decrease in total other income (expense). NINE MONTHS ENDED SEPTEMBER 30, 2008, VERSUS NINE MONTHS ENDED SEPTEMBER 30, 2007 Net Sales. Net sales for the nine months ended September 30, 2008 increased by approximately $18,308,000, or 4%, when compared with the same period last year. Net sales of the Company's automotive mirrors increased by approximately $19,329,000, or 4% period over period, as auto-dimming mirror unit shipments increased by 2% from approximately 11,358,000 in the first nine months of 2007 to 11,593,000 units in the first nine months of 2008. This increase primarily reflected the increased penetration of interior and exterior auto-dimming mirrors on -9-

2008 model year vehicles with overseas customers. Unit shipments to customers in North America decreased by13% during the first nine months of 2008 versus the same period in 2007, primarily due to lower light vehicle production levels at the traditional Big Three automakers and the UAW strikes. The UAW strikes negatively impacted automotive revenues by approximately $8.3 million during the first nine months of 2008 versus the same period in 2007. Mirror unit shipments to automotive customers outside North America increased by 14% year-over-year, primarily due to increased penetration at certain European and Asian automakers. Net sales of the Company's fire protection products decreased 7% year-over-year, primarily due to a weak commercial construction market. Cost of Goods Sold. As a percentage of net sales, cost of goods sold increased from 65% in the nine months ended September 30, 2007, to 66.4% in the nine months ended September 30, 2008, primarily reflecting the impact of annual automotive customer price reductions and the inability to leverage the Company's fixed overhead costs, partially offset by purchasing cost reductions and foreign exchange rates. Each factor is estimated to have impacted cost of goods sold as a percentage of net sales by approximately 1-2%. Operating Expenses. For the nine months ended September 30, 2008, engineering, research and development expenses increased approximately $1,262,000, but remained at 8% of net sales, when compared to the same period last year. Excluding litigation expenses of $104,000 and the litigation judgment accrual reversal of approximately $335,000 for the nine months ended September 30, 2008, and excluding litigation expenses of approximately $4,430,000 for the same period last year (see discussion under "Trends and Developments"), E, R & D expenses increased by 18% when comparing the first nine months of 2008 with the same period last year, primarily due to additional staffing, engineering and testing for new product development, including mirrors with additional features. Selling, general and administrative expenses increased 15% and approximately $3,928,000 for the nine months ended September 30, 2008, and increased from 5% to 6% of net sales period over period, primarily reflecting the continued expansion of the Company's overseas offices and foreign exchange rates. Foreign exchange rates accounted for approximately four percentage points of the increase in selling, general and administrative expenses. Total Other Income. Total other income for the nine months ended September 30, 2008, decreased approximately $18,058,000 when compared to the same period last year, primarily due to increased realized losses on the sale of equity investments (which accounted for approximately two-thirds of the decrease) and lower interest income due to lower interest rates. Taxes. The provision for income taxes varied from the statutory rate during the nine months ended September 30, 2008, primarily due to the domestic manufacturing deduction. Net Income. Net income decreased by approximately $17,827,000, or 20% for the nine months ended September 30, 2008, when compared with the same period last year, primarily due to the decrease in total other income and the reduced operating margin. FINANCIAL CONDITION: Cash flow from operating activities for the nine months ended September 30, 2008, decreased approximately $10,191,000 to $91,007,000, compared to $101,198,000, for the same period last year, primarily due a decrease in net income. Capital expenditures for the nine months ended September 30, 2008, were $38,206,000, compared to $38,937,000 for the same period last year. Cash and cash equivalents as of September 30, 2008, decreased approximately $34,383,000 compared to December 31, 2007. The decrease was primarily due to share repurchases and dividends paid, partially offset by cash flow from operations and short-term investment maturities. Inventories as of September 30, 2008, increased approximately $7,849,000 compared to December 31, 2007. The increase was primarily due to longer lead times on certain electronic components in conjunction with last-minute order release reductions at our customers (including their Tier 1 suppliers). -10-

Long-term investments as of September 30, 2008, decreased approximately $48,763,000 compared to December 31, 2007. The decrease was primarily due to a decrease in unrealized gains in equity investments given current market conditions. Management considers the Company's working capital and long-term investments totaling approximately $529,142,000 as of September 30, 2008, 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 next year and for the foreseeable future. On October 8, 2002, the Company announced a share repurchase plan, under which it may purchase up to 8,000,000 shares (post-split) 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 that the Company deems appropriate. On July 20, 2005, the Company announced that it had raised the price at which the Company may repurchase shares under the existing plan. On May 16, 2006, the Company announced that the Company's Board of Directors had authorized the repurchase of an additional 8,000,000 shares under the plan. On August 14, 2006, the Company announced that the Company's Board of Directors had authorized the repurchase of an additional 8,000,000 shares under the plan. And, on February 26, 2008, the Company announced that the Company's Board of Directors had authorized the repurchase of an additional 4,000,000 shares under the plan. The following is a summary of quarterly share repurchase activity under the plan to date: Total Number of Shares Purchased Cost of Quarter Ended (Post-Split) Shares Purchased ------------- ---------------- ---------------- March 31, 2003 830,000 $ 10,246,810 September 30, 2005 1,496,059 25,214,573 March 31, 2006 2,803,548 47,145,310 June 30, 2006 7,201,081 104,604,414 September 30, 2006 3,968,171 55,614,102 December 31, 2006 1,232,884 19,487,427 March 31, 2007 447,710 7,328,015 March 31, 2008 2,200,752 34,619,490 June 30, 2008 1,203,560 19,043,775 September 30, 2008 2,519,153 39,689,410 ---------- ------------ Total 23,902,918 $362,993,326 4,097,082 shares remain authorized to be repurchased under the plan. CRITICAL ACCOUNTING POLICIES: The preparation of the Company's consolidated condensed financial statements contained in this report, which have been prepared in accordance with accounting principles generally accepted in the Unites States, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, management evaluates these estimates. Estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources. Historically, actual results have not been materially different from the Company's estimates. However, actual results may differ from these estimates under different assumptions or conditions. The Company has identified the critical accounting policies used in determining estimates and assumptions in the amounts reported in its Management's Discussion and Analysis of Financial Condition and Results of Operations in its Annual Report on Form 10-K for the fiscal year ended December 31, 2007. Management believes there have been no significant changes in those critical accounting policies. -11-

TRENDS AND DEVELOPMENTS: The Company previously announced certain development programs with several automakers for its Rear Camera Display (RCD) Mirror that consists of a proprietary liquid crystal display (LCD) that shows a panoramic video of objects behind the vehicle in real time. In addition, the Company previously announced a number of OEM and dealer or port-installed programs for its RCD Mirror. The Company recently announced that its RCD Mirror will be available as factory-installed equipment on the 2009 Toyota Tacoma and FJ Cruiser. The Company also announced that its RCD Mirror is now available through Mito Corporation, a distributor of high-quality aftermarket electronic products and accessories. On February 14, 2008, the President signed into law the "Kids Transportation Safety Act of 2007". The Bill ordered the Secretary of Transportation at the National Highway Traffic Safety Administration (NHTSA) to initiate rulemaking to revise the federal standard to expand the field of view so that drivers can detect objects directly behind vehicles. The Bill states that the requirements may be met by the use of additional mirrors, sensors, cameras or other technology to increase the driver's field of view. The Company's RCD Mirror is a cost competitive product that is relatively easy to implement and may be among the technologies that NHTSA will include as a means to meet the requirements of the legislation. The Company previously announced it is shipping auto-dimming mirrors with SmartBeam, its proprietary intelligent high-beam headlamp assist feature, to General Motors, Chrysler, BMW and Audi for a number of vehicle programs. The Company recently announced that SmartBeam will be offered on the 2009 Chrysler Town & Country minivan and the all-new BMW X6 as a stand-alone option. The Company also announced that SmartBeam will be available throughout Europe on the 2009 Opel Insignia in combination with Opel/Vauxhall's Advanced Forward Lighting, Bi-Xenon headlamp system. During 2005, the Company reached an agreement with PPG Aerospace to work together to provide the variable dimmable windows for the passenger compartment on the new Boeing 787 Dreamliner series of aircraft. Gentex will ship about 100 windows for the passenger compartment of each 787. The Company believes that the commercially viable market for variable dimmable windows is currently limited to the aerospace industry. The Company began shipping parts for test planes in mid-2007. Boeing expects the first planes to go into service in late 2009. Due to the ongoing Boeing machinists strike, we now anticipate that we will begin to deliver our windows to the production line in 2009. The Company and PPG Aerospace recently announced that it will supply dimmable windows to Hawker Beechcraft Corporation for the passenger-cabin windows of the 2010 Beechcraft King Air 350i airplane. The Company has a long-term agreement with General Motors (GM) in the ordinary course of the Company's business. Under the agreement, the Company was sourced virtually all the interior auto-dimming rearview mirror programs for GM and its worldwide affiliates through August 2009. During the quarter ended September 30, 2008, the Company negotiated an extension to the existing agreement, through August 1, 2012, in the ordinary course of the Company's business. The Company currently expects that top line revenue growth for the fourth quarter of 2008 will be approximately 15% lower, compared with the same period in 2007. These estimates are based on current light vehicle production forecasts in the regions to which the Company ships product, as well as the estimated option rates for its mirrors on prospective vehicle models. Uncertainties include light vehicle production levels, extended automotive plant shutdowns, sales rates in North America, Europe and Asia, and the impact of potential automotive customer (including their Tier 1 suppliers) work stoppages, strikes, etc., which could disrupt our shipments to these customers, making forecasting difficult. Currently, it is an extremely difficult environment to forecast due to uncertainties associated with the global economy, financial markets and the uncertain light vehicle production environment. The Company also estimates that engineering, research and development expenses, excluding Muth litigation costs, are currently expected to increase approximately 10% in the fourth quarter of 2008 compared with the same period in 2007. Selling, general and administrative expenses are currently expected to increase approximately 10-15% in the fourth quarter of 2008 compared with the same period in 2007. The Company utilizes the light vehicle production forecasting services of CSM Worldwide, and CSM's current mid-October forecasts for light vehicle production for calendar year 2008 are approximately 12.9 million units for North America, 21.5 million for Europe and 14.8 million for Japan and Korea. -12-

The Company is subject to increased market risk exposures of varying correlations and volatilities due to the turmoil in the financial markets, including foreign exchange rate risk, interest rate risk and equity price risk. During the quarter ended September 30, 2008, there were no material changes in the risk factors previously disclosed in the Company's report on Form 10-K for the fiscal year ended December 31, 2007. 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, the Company is significantly affected by weak economic conditions in worldwide markets that are reducing demand for its products. The Company continues to experience significant 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 or yield improvements, engineering and purchasing cost reductions, and increases in unit sales volume, all of which continue to be a challenge in the current automotive production environment. In addition, financial pressures at certain automakers are resulting in increased cost reduction efforts by them, including requests for additional price reductions, decontenting certain features from vehicles, customer market testing of future business, dual sourcing initiatives and warranty cost-sharing programs, which could adversely impact the Company's sales growth, margins, profitability and, as a result, our share price. The Company also continues to experience some manufacturing yield issues and pressure for select raw material cost increases. In addition to the foregoing, the Company is planning for a new computer system which has the potential for implementation issues during 2009. The automotive industry is cyclical and highly impacted by levels of economic activity, which in the current environment is causing increased financial and production stresses evidenced by continuing pricing pressures, lower domestic production levels (especially in the pickup truck and SUV segment in North America due to high fuel prices), consumer preference shift to smaller vehicles where Gentex has a lower penetration rate and lower content per vehicle due to higher fuel prices, supplier and potential OEM bankruptcies, and commodity material cost increases. If the Company's automotive customers (including their Tier 1 suppliers) experience work stoppages, strikes, etc. due to their union contracts or other negotiations, it could disrupt the Company's shipments to these customers, which adversely affect the Company's sales, margins, profitability and, as a result, our share price. Automakers have also 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, effectively manage costs and utilize capital, engineering, research and development, and human resource investments. In light of the financial stresses within the worldwide automotive industry, certain automakers and tier one mirror customers are considering the sale of certain business segments and/or may be considering bankruptcy. Should one or more of the Company's larger customers (including their tier 1 suppliers) sell their business or declare bankruptcy, it could adversely affect the collection of receivables, our sales, margins, profitability and, as a result, the Company's share price. The Company does not have any significant off-balance sheet arrangements or commitments that have not been recorded in its consolidated financial statements. The Company was involved in litigation with K. W. Muth and Muth Mirror Systems LLC relating to exterior mirrors with turn signal indicators. The turn signal feature in exterior mirrors that was the subject of the litigation represents approximately one percent of the Company's revenues, and the litigation did not involve core Gentex electrochromic technology. The trial in Wisconsin related to this case occurred in July 2007 and the Court issued its written ruling in December 2007. The Court found that Muth's U.S. patent No. 6,005,724 was invalid and unenforceable, and that Gentex's Razor Turn Signal Mirror did not infringe that patent. The Court also denied all but one of Muth's other motions with prejudice, including its motion for an injunction, and its claims for tortious interference with its business relationships. The sole point of liability for Gentex was that the Court found that Gentex breached one provision of the alliance agreement it has with Muth, and entered a judgment against Gentex, on January 24, 2008, granting Muth damages in the amount of $2,885,000, which was accrued by the Company as of December 31, 2007. On February 15, 2008, the Company entered into a Settlement And Release And Covenants Not To Sue ("Agreement") with Muth whereby the parties agreed to settle the Court's judgment against the Company for damages at a reduced amount of $2,550,000. In addition, under the Agreement the parties each -13-

agreed to: grant the other party a ten-year covenant not to sue for each Company's core business, to release each other from all claims that occurred in the past, and not appeal the Court's rulings. The Agreement was approved by the Bankrupcty Court on February 29, 2008. The adjustment to the original judgment for damages is reflected in our first quarter financial results as a reduction to engineering, research and development expenses. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. The information called for by this item is provided under the caption "Trends and Developments" under Item 2 - Management's Discussion and Analysis of Financial Condition and Results of Operations. ITEM 4. CONTROLS AND PROCEDURES. The Company's management, with the participation of its principal executive officer and principal financial officer, has evaluated the effectiveness, as of September 30, 2008, of the Company's "disclosure controls and procedures," as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based upon that evaluation, the Company's management, including the principal executive officer and principal financial officer, concluded that the Company's disclosure controls and procedures, as of September 30, 2008, were adequate and effective such that the information required to be disclosed by the Company in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and information required to be disclosed by the Company in such reports is accumulated and communicated to the Company's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. In the ordinary course of business, the Company may routinely modify, upgrade, and enhance its internal controls and procedures over financial reporting. However, there was no change in the Company's "internal control over financial reporting" [as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act] that occurred during the quarter ended September 30, 2008, that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting. SAFE HARBOR STATEMENT: Statements in this Quarterly Report on Form 10-Q contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act, as amended, that are based on management's belief, assumptions, current expectations, estimates and projections about the global automotive industry, the economy, the impact of stock option expense, the ability to leverage fixed manufacturing overhead costs, unit shipment and revenue growth rates, the ability to control E,R&D and S,G&A expenses, gross margins and the Company itself. Words like "anticipates," "believes," "confident," "estimates," "expects," "forecast," "likely," "plans," "projects," and "should," and variations of such words and similar expressions identify forward-looking statements. These statements do not guarantee future performance and involve certain risks, uncertainties, and assumptions that are difficult to predict with regard to timing, expense, likelihood and degree of occurrence. These risks include, without limitation, employment and general economic conditions, the pace of automotive production worldwide, the maintenance of the Company's market share, the ability to achieve purchasing cost reductions, competitive pricing pressures, currency fluctuations, interest rates, equity prices, the financial strength of the Company's customers, supply chain disruptions, potential sale of OEM business segments or suppliers, the mix of products purchased by customers, the ability to continue to make product innovations, the success of certain newer products (e.g. SmartBeam, Z-Nav(R) and Rear Camera Display Mirror), and other risks identified in the Company's filings with the Securities and Exchange Commission. Therefore, actual results and outcomes may materially differ from what is expressed or forecasted. Furthermore, the Company undertakes no obligation to update, amend, or clarify forward-looking statements, whether as a result of new information, future events, or otherwise. -14-
