              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(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 2004 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

(4)   All earnings per share amounts, weighted daily average of shares of common
      stock outstanding, common stock, and additional paid-in capital have been
      restated, to reflect the Company's announcement on April 1, 2005, of a
      two-for-one stock split effected in the form of a 100 percent common stock
      dividend for each outstanding share, issued to shareholders on May 6,
      2005. The ex-dividend date was May 9, 2005.

(5)   The following table reconciles the numerators and denominators used in the
      calculation of basic and diluted earnings per share (EPS):

(6)   At June 30, 2005, the Company had two stock option plans and an employee
      stock purchase plan. 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 due to these plans is reflected in net income,
      since 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.

      On March 30, 2005, in response to the required implementation of SFAS No.
      123(R) as disclosed in Note 10, the Company accelerated the vesting of
      current "under water" stock options. As a result of the vesting
      acceleration, approximately 2.3 million shares became immediately
      exercisable and an additional approximate $13.6 million of proforma
      stock-based employee compensation expense was recognized in the first
      quarter. The objective of this Company action is primarily to avoid
      recognizing compensation expense associated with these options in future
      financial statements, upon the Company's adoption of SFAS No. 123(R). In
      addition, the Company has also received shareholder approval of an
      amendment to its Employee Stock Option Plan to allow the grant of
      non-qualified stock options.

(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:



                    June 30, 2005   June 30, 2004
                    -------------   -------------

Six Months Ended     $49,922,035     $59,752,161


(8)   The increase in common stock during the quarter and six months ended June
      30, 2005, was attributable to the issuance of 550,891 and 776,137 shares,
      respectively, of the Company's common stock under its stock-based
      compensation plans. The Company has also recorded a $0.085 per share cash
      dividend in the first and second quarters. The second quarter dividend of
      approximately $13,303,000, was declared on May 17, 2005, and was paid on
      July 22, 2005.

(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:

(10)  On December 16, 2004, the Financial Accounting Standards Board (FASB)
      issued SFAS Statement No. 123(R), "Share-Based Payment," which required
      all share-based payments to employees, including grants of employee stock
      options, to be recognized in the income statement based on their fair
      values, and was effective for public companies for interim or annual
      periods beginning after June 15, 2005. On April 14, 2005, the U.S.
      Securities and Exchange Commission announced that companies will be
      allowed to implement SFAS No. 123(R) at the beginning of their next fiscal
      year after June 15, 2005. The Company does not intend to adopt a
      fair-value based method of accounting for stock-based employee
      compensation until required (January 1, 2006). Proforma quarterly earnings
      and certain Company actions taken in response to SFAS No. 123(R) are
      disclosed in Note 5 of this quarterly statement.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
        FINANCIAL CONDITION

        RESULTS OF OPERATIONS:

        SECOND QUARTER 2005 VERSUS SECOND QUARTER 2004

        Net Sales. Net sales for the second quarter of 2005 increased by
        approximately $2,738,000, or 2%, when compared with the second quarter
        last year. Net sales of the Company's automotive auto-dimming mirrors
        increased by approximately $2,292,000, or 2%, in the second quarter of
        2005, when compared with the second quarter last year, primarily due to
        a 3% increase in auto-dimming mirror unit shipments from approximately
        3,001,000 in the second quarter of 2004 to 3,095,000 in the current
        quarter. This unit increase primarily reflected the increased
        penetration of interior auto-dimming mirrors on 2005 model year vehicles
        during the second quarter of 2005. Unit shipments to customers in North
        America for the current quarter increased by 1% compared with the second
        quarter of the prior year, primarily due to higher unit shipments to
        transplants, partially offset by lower light vehicle production levels
        at certain North-American-based automakers. Mirror unit shipments for
        the current quarter to automotive customers outside North America
        increased by 5% compared with the second quarter in 2004, primarily due
        to increased penetration. Net sales of the Company's fire protection
        products increased 8% for the current quarter, primarily due to stronger
        sales of certain fire alarms and signal products.

        Cost of Goods Sold. As a percentage of net sales, cost of goods sold
        increased from 58% in the second quarter of 2004 to 63% in the second
        quarter of 2005. This percentage increase primarily reflected automotive
        customer price reductions, higher fixed overhead expenses and lower
        mirror unit shipment growth resulting in reduced capacity utilization.
        Each factor is estimated to have impacted cost of goods sold as a
        percentage of net sales by approximately 1-2 percentage points.

        Operating Expenses. Engineering, research and development expenses for
        the current quarter increased approximately $1,252,000, from 6% to 7% of
        net sales, when compared with the same quarter last year, primarily
        reflecting additional staffing, engineering and testing for new product
        development, including mirrors with additional electronic features.
        Selling, general and administrative expenses increased approximately
        $131,000, for the current quarter, but remained at 5% of net sales, when
        compared with the second quarter of 2004. This increased expense
        primarily reflected the continued expansion of the Company's overseas
        sales offices, partially offset by a reduction in state taxes.

        Total Other Income. Total other income for the current quarter increased
        by approximately $1,350,000 when compared with the second quarter of
        2004, primarily due to increased interest income due to higher interest
        rates, partially offset by lower miscellaneous other income.

        Income Taxes. The Company's effective income tax rate decreased from
        32.5% in the second quarter of 2004 to 31.5% in the second quarter of
        2005, primarily due to increased tax-exempt investment income.

        SIX MONTHS ENDED JUNE 30, 2005, VERSUS SIX MONTHS ENDED JUNE 30, 2004

           Net Sales. Net sales for the six months ended June 30, 2005,
        increased by $1,052,000, or 0.4%, when compared with the same period
        last year. Net sales of the Company's automotive auto-dimming mirrors
        increased by $520,000, or 0.2%, as auto-dimming mirror unit shipments
        increased by 2% from approximately 5,983,000 in the first six months of
        2004 to 6,125,000 units in the first six months of 2005. This increase
        primarily reflected the increased penetration of interior auto-dimming
        mirrors on 2005 model year vehicles. Unit shipments to customers in
        North America decreased by 2%, as a result of reduced shipments to
        domestic automakers due to their lower production levels that were
        partially offset by increased unit shipments to transplants. Mirror
        shipments to automotive customers outside North America increased by 6%,
        primarily due to increased penetration of auto-dimming mirrors on 2005
        model year vehicles. Net sales of the Company's fire protection products
        increased 5% in the first six months of 2005 versus the first six months
        of 2004, primarily due to stronger sales of certain fire alarm and
        signal products.
                                       -8-


           Cost of Goods Sold. As a percentage of net sales, cost of goods sold
        increased from 58% in the six months ended June 30, 2004, to 62% in the
        six months ended June 30, 2005, primarily reflecting automotive customer
        price reductions, higher fixed overhead expenses, and lower mirror unit
        shipment growth resulting in reduced capacity utilization. Each factor
        is estimated to have impacted cost of goods sold by approximately 1-2
        percentage points.

           Operating Expenses. For the six months ended June 30, 2005,
        engineering, research and development expenses increased approximately
        $1,786,000, but remained at 6% of net sales, when compared to the same
        period last year, primarily due to additional staffing, engineering and
        testing for new product development, including mirrors with additional
        electronic features. Selling, general and administrative expenses
        increased approximately $226,000 for the six months ended June 30, 2005,
        but remained at 5% of net sales, when compared to the same period last
        year, primarily reflecting the continued expansion of the Company's
        overseas sales offices, partially offset by a reduction in state taxes.

           Other Income - Net. Other income for the six months ended June 30,
        2005, increased $2,498,000 when compared to the same period last year,
        primarily due to increased interest income, partially offset by lower
        miscellaneous other income.

           Taxes. The Company's effective income tax rate decreased from 32.5%
        in the six months ended June 30, 2004, to 31.5% in the six months ended
        June 30, 2005, primarily due to increased tax-exempt investment income.

        FINANCIAL CONDITION:

        Cash flow from operating activities for the six months ended June 30,
        2005, decreased to $70,680,000, compared to $71,598,000, for the same
        period last year, primarily due to lower net income. Capital
        expenditures for the six months ended June 30, 2005, increased to
        $28,729,000, compared to $14,175,000 for the same period last year,
        primarily due to new facility construction.

        The Company currently expects that the construction of its fourth
        automotive manufacturing facility and a new technical center will be
        completed in the spring of 2006. The Company plans to invest
        approximately $35-40 million for the new facilities during 2004-2006,
        which will be funded from its cash and cash equivalents on hand.

        Cash and cash equivalents as of June 30, 2005, increased approximately
        $16,753,000 compared to December 31, 2004. The increase was primarily
        due to cash flow from operations, less dividends paid.

        Accounts payable as of June 30, 2005, increased $11,675,000, compared to
        December 31, 2004. The increase was primarily due to increased capital
        spending and the timing of weekly payments.

        Management considers the Company's working capital and long-term
        investments totaling approximately $679,123,000 as of June 30, 2005,
        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. During the quarter ended
        March 31, 2003, the Company repurchased 830,000 shares (post-split) at a
        cost of approximately $10,247,000. No shares have been repurchased
        subsequently by the Company.

        TRENDS AND DEVELOPMENTS:

        During the first quarter of 2005, the Company negotiated an extension to
        its long-term agreement with General Motors in the ordinary course of
        the Company's business. Under the extension, Gentex will be sourced all
        of the interior auto-dimming rearview mirrors programs for GM and its
        worldwide affiliates through August 2009, and includes all but two
        low-volume models that had previously been awarded to a Gentex
        competitor under a lifetime contract. The new business also includes the
        GMT360 program, which is the mid-size truck/SUV platform that currently
        does not offer auto-dimming mirrors. The new GM programs will be
        transferred to Gentex by no later

                                       -9-


        than the 2007 model year. We currently estimate that this new business
        represents incremental auto-dimming mirror units in the range of 500,000
        on an annualized basis. The Company also negotiated a price reduction
        for the GM OnStar feature in its auto-dimming mirrors, effective January
        1, 2005, in connection with GM's plan to make their OnStar system
        standard across their vehicle models over the next several years.

        The Company currently expects that auto-dimming mirror unit shipments
        will be 5-10% higher in the third quarter of 2005 compared with the
        third quarter of 2004, and 10-15% higher in the fourth quarter of 2005
        compared with the fourth quarter of 2004. These estimates are based on
        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.

        The Company utilizes the light vehicle production forecasting services
        of CSM Worldwide, and CSM's current forecasts for light vehicle
        production for calendar 2005 are approximately 15.7 million units for
        North America, 20.5 million for Europe and 13.1 million for Japan and
        Korea.

        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. During the quarter ended June 30, 2005,
        there were no significant changes in the market risks reported in the
        Company's 2004 Form 10-K report.

        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 worldwide markets
        that could reduce demand for its products.

        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 improvements, engineering and
        purchasing cost reductions, and increases in unit 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 select raw material cost
        increases. The automotive industry is experiencing increasing financial
        stresses due to continuing pricing pressures, lower domestic production
        levels, and commodity material cost increases.

        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.

        On March 30, 2005, in response to the required implementation of SFAS
        No. 123(R) as disclosed in Note 10, the Company accelerated the vesting
        of current "under water" stock options. As a result of the vesting
        acceleration, approximately 2.3 million shares became immediately
        exercisable and an additional approximate $13.6 million of proforma
        stock-based employee compensation expense was recognized in the first
        quarter. The objective of this Company action is primarily to avoid
        recognizing compensation expense associated with these options in future
        financial statements, upon the Company's adoption of SFAS No. 123(R). In
        addition, the Company has also received shareholder approval of an
        amendment to its Employee Stock Option Plan to allow the grant of
        non-qualified stock options.

        On April 1, 2005, the Company announced a two-for-one stock split
        effected in the form of a 100 percent common stock dividend for each
        outstanding share, issued to shareholders on May 6, 2005. The
        ex-dividend date was May 9, 2005.

                                      -10-


        On October 1, 2002, Magna International acquired Donnelly Corporation,
        the Company's major competitor for sales of automatic-dimming rearview
        mirrors to domestic and foreign vehicle manufacturers and their mirror
        suppliers. The Company sells certain automatic-dimming rearview mirror
        sub-assemblies to Magna Donnelly. To date, the Company is not aware of
        any significant impact of Magna's acquisition of Donnelly upon the
        Company; however, any ultimate significant impact has not yet been
        determined.

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 Results of Operations and Financial Condition.

ITEM 4. CONTROLS AND PROCEDURES

        As of June 30, 2005, an evaluation was performed under the supervision
        and with the participation of the Company's management, including the
        CEO and CFO, of the effectiveness of the design and operation of the
        Company's disclosure controls and procedures [(as defined in Exchange
        Act Rules 13a - 15(e) and 15d - 15(e)]. Based on that evaluation, the
        Company's management, including the CEO and CFO, concluded that the
        Company's disclosure controls and procedures were adequate and effective
        as of June 30, 2005, to ensure that material information relating to the
        Company would be made known to them by others within the Company,
        particularly during the period in which this Form 10-Q was being
        prepared. During the period covered by this quarterly report, there have
        been no changes in the Company's internal controls over financial
        reporting that have materially affected or are likely to materially
        affect the Company's internal controls over financial reporting.

        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, about the global automotive industry, the economy and the
        Company itself, and involve risks and uncertainties described under the
        headings "Management's Discussion and Analysis of Results of Operations
        and Financial Condition" and "Trends and Developments." 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 economic recovery in the U.S.
        and in international markets, automotive production levels worldwide,
        the types of products purchased by customers, competitive pricing
        pressures, currency fluctuations, the financial strength of the
        Company's customers, the mix of products purchased by customers, the
        ability to continue to make product innovations, the success of newly
        introduced products (e.g. SmartBeam), 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.
