                       GENTEX CORPORATION AND SUBSIDIARIES

              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 2003 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, 2004, and the
      results of operations and cash flows for the interim periods presented.

(5)   At September 30, 2004, 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 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.

(6)   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, 2004     September  30, 2003
                  ------------------     -------------------

Nine Months Ended      82,850,918              89,260,627

(7)   The increase in common stock during the quarter and nine months ended
      September 30, 2004, was attributable to the issuance of 198,005 and
      611,189 shares, respectively, of the Company's common stock under its
      stock-based compensation plans. The Company has also recorded a $0.15 per
      share cash dividend in the first two quarters of 2004 and a $0.17 per
      share cash dividend in the third quarter. The third quarter dividend of
      approximately $13,201,000, was declared on August 18, 2004, and is payable
      on October 21, 2004.

(8)   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:

          NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONT.)

(9)   On October 13, 2004, the Financial Accounting Standards Board (FASB)
      concluded that FASB Statement No. 123R, "Share-Based Payment," which would
      require all share-based payments to employees, including grants of
      employee stock options, to be recognized in the income statement based on
      their fair values, would be effective for public companies for interim or
      annual periods beginning after June 15, 2005. 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 requires
      this accounting. Proforma disclosures of quarterly earnings are included
      in Note 5 of this quarterly statement.

      In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
      Variable Interest Entities." This standard clarifies the application of
      Accounting Research Bulletin No. 51, "Consolidated Financial Statements,"
      and addresses consolidation by business enterprises of variable interest
      entities. Interpretation No. 46 requires existing unconsolidated variable
      interest entities to be consolidated by their primary beneficiaries if the
      entities do not effectively disperse risk among the parties involved.
      Interpretation No. 46 also enhances the disclosure requirements related to
      variable interest entities. This interpretation was effective for any
      variable interest entered into by the Company as of the end of the first
      quarter of 2004. The adoption of Interpretation No. 46 did not have any
      significant effect on the Company's consolidated financial statements.

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

      RESULTS OF OPERATIONS:

      THIRD QUARTER 2004 VERSUS THIRD QUARTER 2003

      Net Sales. Net sales for the third quarter of 2004 increased by
      approximately $7,578,000, or 7%, when compared with the third quarter last
      year. Net sales of the Company's automotive auto-dimming mirrors increased
      by approximately $7,526,000, or 7%, in the third quarter of 2004, when
      compared to the third quarter last year, as auto-dimming mirror unit
      shipments increased by 11% from approximately 2,475,000 in the third
      quarter of 2003 to 2,756,000 in the current quarter. This increase
      reflected the increased penetration of interior auto-dimming mirrors on
      2004 and 2005 model year vehicles during the third quarter of 2004. Unit
      shipments to customers in North America for the current quarter decreased
      by 1% compared with the third quarter of the prior year, primarily due to
      lower exterior mirror shipments as the result of end of the model year
      inventory adjustments by certain tier one exterior mirror suppliers.
      Mirror unit shipments for the current quarter to automotive customers
      outside North America increased by 26% compared with the third quarter in
      2003, primarily due to increased interior mirror shipments to European and
      Asian-Pacific automakers as a result of increased penetration. Net sales
      of the Company's fire protection products increased 1% for the current
      quarter, primarily due to higher sales of certain of the Company's
      signaling products.

      Cost of Goods Sold. As a percentage of net sales, cost of goods sold
      increased from 58.3% in the third quarter of 2003 to 60.4% in the third
      quarter of 2004. This percentage increase primarily reflected annual
      customer price reductions and start-up costs related to the introduction
      of a number of new automated manufacturing processes during the quarter.
      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
      quarter increased approximately $814,000, from 6.2% to 6.4% 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 $857,000, for the
      quarter, from 5.0% to 5.4% of net sales, when compared with the third
      quarter of 2003. This increased expense primarily reflected the continued
      expansion of the Company's overseas sales and engineering offices.

      Total Other Income. Total other income for the quarter decreased by
      approximately $165,000 when compared with the third quarter of 2003,
      primarily due to reduced interest income due to a higher proportion of
      tax-exempt investments.

      Income Taxes. The Company's effective income tax rate decreased from 32.5%
      in the third quarter of 2003 to 31.5% in the third quarter of 2004,
      primarily due to higher tax-exempt investment income.

      NINE MONTHS ENDED SEPTEMBER 30, 2004, VERSUS NINE MONTHS ENDED SEPTEMBER
      30, 2003

      Net Sales. Net sales for the nine months ended September 30, 2004,
      increased by approximately $34,326,000, or 10%, when compared with the
      same period last year. Net sales of the Company's automotive auto-dimming
      mirrors increased by approximately $34,020,000, or 10%, as auto-dimming
      mirror unit shipments increased by 16% from approximately 7,544,000 in the
      first nine months of 2003 to 8,739,000 in the first nine months of 2004.
      This increase reflected the increased penetration on 2004 and 2005 model
      year vehicles for interior and exterior auto-dimming mirrors. Unit
      shipments to customers in North America increased by 5% for the first nine
      months of 2004 compared with the same period last year, primarily due to
      increased penetration among Asian transplants. Mirror unit shipments to
      automotive customers outside North America increased by 29% for the first
      nine months of 2004 compared with the first nine months in 2003, primarily
      due to increased interior and exterior mirror sub-assembly shipments to
      European and Asian-Pacific automakers as a result of increased
      penetration. Net sales of

                                     - 8 -


      the Company's fire protection products increased 2% for the first nine
      months of 2004, primarily due to higher sales of certain of the Company's
      signaling products.

      Cost of Goods Sold. As a percentage of net sales, cost of goods sold
      increased slightly from 58.4% to 58.6% in the first nine months of 2004,
      when compared to the same nine-month period in the prior year. This slight
      percentage increase primarily reflected annual customer price reductions,
      mostly offset by the higher sales level leveraged over the fixed overhead
      costs and product mix. 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. For nine months ended September 30, 2004, engineering,
      research and development expenses increased approximately $3,285,000, from
      5.6% to 6.0% of net sales, when compared with the same period last year,
      primarily reflecting additional staffing for new product development,
      including mirrors with additional electronic features. Selling, general
      and administrative expenses increased approximately $2,865,000 for the
      first nine months of 2004, and increased from 5.0% to 5.3% of net sales
      when compared to the first nine months of 2003. This increased expense
      primarily reflected the continued expansion of the Company's overseas
      sales and engineering office as well as the stronger euro exchange rate.

      Other Income - Net. Other income for the nine months ended September 30,
      2004, increased by approximately $1,446,000 when compared with the first
      nine months of 2003, primarily due to realized gains on the sale of equity
      investments in the current year period, partially offset by reduced
      interest income due to lower interest rates.

      FINANCIAL CONDITION:

      Cash flow from operating activities for the nine months ended September
      30, 2004, increased $17,340,000 to $94,693,000, compared to $77,353,000,
      for the same period last year, primarily due to lower growth in accounts
      receivable and increased net income. During the third quarter of 2003, the
      Company's largest customer extended its payment terms to its suppliers,
      which resulted in a one-time increase in accounts receivable. Capital
      expenditures for the nine months ended September 30, 2004, were
      $20,706,000, compared to $15,982,000 for the same period last year.

      The Company now expects that the construction of its fourth automotive
      manufacturing facility and a new corporate facility will be completed in
      early 2006. The completion date has been pushed back from the original
      date due to improved manufacturing capacity utilization. The Company plans
      to invest approximately $40-45 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 September 30, 2004, increased
      approximately $85,255,000 compared to December 31, 2003. The increase was
      primarily due to cash flow from operations.

      Management considers the Company's working capital and long-term
      investments totaling approximately $638,362,000 as of September 30, 2004,
      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 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 that the Company deems appropriate. During the quarter ended March
      31, 2003, the Company repurchased 415,000 shares at a cost of
      approximately $10,247,000. No shares have been repurchased subsequently by
      the Company.

      TRENDS AND DEVELOPMENTS:

      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 September 30, 2004, there
      were no significant changes in the market risks reported in the Company's
      2003 Form 10-K report.

                                     - 9 -


      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 from time to time some
      pressure for select raw 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 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.

      "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 September 30, 2004, 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 September 30, 2004, 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.

      "anticipation" or "expectation" as well as other statements which are not
      historical fact, are forward-looking statements 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" that could cause actual results to differ materially from
      those projected. All forward-looking statements in this Report are based
      on information available to the Company on the date hereof, and the
      Company assumes no obligation to update any such forward-looking
      statements.
