(6)  Stock-Based Compensation Plans

     At March 31, 2006, the Company had two stock option plans, a restricted
     stock plan and an employee stock purchase plan, which are described more
     fully below. Effective January 1, 2006, the Company adopted SFAS No. 123
     (revised), "Share-Based Payment" [SFAS 123(R)] utilizing the modified
     prospective approach. Prior to the adoption of SFAS 123(R) we accounted for
     stock option grants under the recognition and measurement principles of APB
     Opinion No. 25 (Accounting for Stock Issued to Employees) and related
     interpretations, and accordingly, recognized


                                      -5-



                       GENTEX CORPORATION AND SUBSIDIARIES

          NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONT.)

     no compensation expense for stock option grants in net income. 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, 2005,
     for additional information related to these stock-based compensation plans.

     Under the modified prospective approach, SFAS 123(R) applies to new awards
     and to awards that were outstanding on December 31, 2005. Under the
     modified prospective approach, compensation cost recognized in the first
     quarter of 2006 includes compensation cost for all share-based payments
     granted prior to, but not yet vested as of December 31, 2005, based on the
     grant-date fair value estimated in accordance with the original provisions
     of SFAS 123, and compensation cost for all share-based payments granted
     subsequent to December 31, 2005, based on the grant-date fair value
     estimated in accordance with the provisions of SFAS 123 (R). Prior periods
     were not restated to reflect the impact of adopting the new standard.

     As a result of adopting SFAS 123(R) on January 1, 2006, the Company's
     income before taxes, net income and basic and diluted earnings per share
     for the three months ended March 31, 2006, were $1,720,095, $922,921, and
     $.01 lower, respectively, than if we had continued to account for
     stock-based compensation under APB Opinion No. 25 for our stock option
     grants. Compensation cost capitalized as part of inventory for the three
     months ended March 31, 2006 was $80,568. The cumulative effect of the
     change in accounting for forfeitures was not material.

     We receive a tax deduction for certain stock option exercises during the
     period the options are exercised, generally for the excess of the price at
     which the options are sold over the exercise price of the options. Prior to
     the adoption of SFAS 123(R), we reported all tax benefits resulting from
     the exercise of stock options as operating cash flows in our consolidated
     statement of cash flows. In accordance with SFAS 123(R), for the three
     months ended March 31, 2006, we revised our consolidated statement of cash
     flows presentation to report the tax benefits from the exercise of stock
     options as financing cash flows. For the three months ended March 31, 2006,
     $76,044 of tax benefits from the exercise of stock options and vested
     restricted stock were reported as financing cash flows rather than
     operating cash flows.

     Net cash proceeds from the exercise of stock options and employee stock
     purchases were $6,340,969 for the three months ended March 31, 2006. The
     actual income tax benefit realized from stock option exercises and vested
     restricted stock are $695,311 for the same period.

     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 for the
     three months ended March 31, 2005:

          NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONT.)

     On March 30, 2005, in response to the required implementation of SFAS No.
     123(R), 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 2005, that otherwise would have been
     recognized as follows: $6.1 million in 2005; $4.5 million in 2006; $2.2
     million in 2007 and $0.8 million in 2008-2009. The objective of this
     Company action was primarily to avoid recognizing compensation expense
     associated with these options in future financial statements, upon the
     Company's adoption of SFAS 123(R), effective January 1, 2006. In addition,
     the Company also received shareholder approval of an amendment to its
     Employee Stock Option Plan to allow the grant of non-qualified stock
     options.

EMPLOYEE STOCK OPTION PLAN

     In 2004, a new Employee Stock Option Plan was approved, replacing the prior
     plan. The Company may grant options for up to 18,000,000 shares under its
     new Employee Stock Option Plan. The Company has granted options on
     4,628,133 shares (net of shares from canceled options) under the new plan
     through March 31, 2006. 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 three to seven years.

     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
                                               March 31

                                           ------   ------
                                              
Dividend Yield                               2.11%    2.13%
Expected Volatility                         30.76%   43.20%
Risk-free interest rate                      4.82%    4.06%
Expected term of options (in years)          4.37     4.37
Weighted-average grant-date fair value     $ 4.64   $ 5.46


     The Company determined that all employee groups exhibit similar exercise
     and post-vesting termination behavior to determine the expected term.

     As of March 31, 2006, there was $9,263,785 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 4.4 years.

     March 31, 2006, and changes during the quarter is presented in the table

NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

     The Company has a Non-employee Director Stock Option Plan covering
     1,000,000 shares that was approved, replacing a prior plan. The Company has
     granted options on 309,240 shares (net of shares from canceled options)
     under the current plan through March 31, 2006. 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.

     As of March 31, 2006, there was no unrecognized compensation cost related
     to these share-based payments.

     For the three months ended March 31, 2006, the Company did not have any
     non-vested stock option activity.

EMPLOYEE STOCK PURCHASE PLAN

     In 2003, a new Employee Stock Purchase Plan covering 1,200,000 shares was
     approved, replacing a prior plan. The company has sold a total of 346,257
     shares under the new plan through March 31, 2006. 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 2006 was approximately $14.76.

RESTRICTED STOCK PLAN

     The Company has a Restricted Stock Plan covering 1,000,000 shares of common
     stock that was approved, the purpose of which 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 a committee, appointed by the Board of
     Directors, but may not exceed ten years. The Company has 506,240 shares
     outstanding as of March 31, 2006, and 22,860 shares were granted with a
     restriction period of five years at a market price of $17.09 during the 1st
     quarter 2006. As of March 31, 2006, the company has unearned stock-based
     compensation of $4,811,399 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.

(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:

(8)  The decrease in common stock during the three months ended March 31, 2006,
     was primarily due to the repurchase of 2,803,548 shares for approximately
     $47,145,000, partially offset by the issuance of 517,852 shares,
     respectively, of the Company's common stock under its stock-based
     compensation plans. The Company has also recorded a $0.09 per share cash
     dividend in the first quarter. The first quarter dividend of approximately
     $13,838,000, was declared on March 2, 2006, and was paid on April 21, 2006.

(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:

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

     RESULTS OF OPERATIONS:

     FIRST QUARTER 2006 VERSUS FIRST QUARTER 2005

     Net Sales. Net sales for the first quarter of 2006 increased by
     approximately $11,379,000, or 9%, when compared with the first quarter last
     year. Net sales of the Company's automotive auto-dimming mirrors increased
     by approximately $11,270,000, or 9%, in the first quarter of 2006, when
     compared with the first quarter last year, primarily due to a 12% increase
     in auto-dimming mirror unit shipments from approximately 3,030,000 in the
     first quarter of 2005 to 3,392,000 in the current quarter. This unit
     increase primarily reflected the increased penetration of interior and
     exterior auto-dimming mirrors on 2006 model year vehicles. Unit shipments
     to customers in North America for the current quarter increased by 7%
     compared with the first quarter of the prior year, primarily due to
     increased penetration at General Motors and Asian transplant automakers,
     partially offset by reduced shipments to Chrysler and Ford. Mirror unit
     shipments for the current quarter to automotive customers outside North
     America increased by 16% compared with the first quarter in 2005, primarily
     due to increased penetration at certain European and Asian automakers. Net
     sales of the Company's fire protection products increased 2% for the
     current quarter versus the same quarter of last year, primarily due to
     stronger sales of certain fire alarm products.

     Cost of Goods Sold. As a percentage of net sales, cost of goods sold
     increased from 62% in the first quarter of 2005 to 65% in the first quarter
     of 2006. This percentage increase primarily reflected the impact of
     automotive customer price reductions, the inability to leverage the
     Company's fixed overhead costs, and stock option expense. Each factor is
     estimated to have impacted cost of goods sold by 1 - 2 percentage points.

     Operating Expenses. Engineering, research and development expenses for the
     current quarter increased 27% and approximately $2,182,000, 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, and stock option expensing. Excluding stock
     option expense, E, R & D expenses increased by 19%. Selling, general and
     administrative expenses increased 14% and approximately $951,000, for the
     current quarter, when compared with the first quarter of 2005. This
     increased expense primarily reflected stock option expensing and the
     continued expansion of the Company's overseas sales offices. Excluding
     stock option expense, S, G & A expenses increased by 6%.

     Total Other Income. Total other income for the current quarter increased by
     approximately $3,365,000 when compared with the first quarter of 2005,
     primarily due to increased interest income due to higher interest rates and
     realized gains on the sale of equity investments.

     Taxes. The provision for income taxes varied from the statutory rate during
     the current quarter, primarily due to Extra Territorial Income Exclusion
     Act exempted taxable income, domestic production exclusion, tax-exempt
     investment income and stock option expense.

     FINANCIAL CONDITION:

     Cash flow from operating activities for the three months ended March 31,
     2006, decreased to $38,473,000, compared to $42,735,000, for the same
     period last year, primarily due to an increase in accounts receivable and a
     decrease in accounts payable. Capital expenditures for the three months
     ended March 31, 2006, increased to $12,935,000, compared to $11,129,000 for
     the same period last year, including the 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.

     Accounts receivable as of March 31, 2006, increased approximately
     $9,491,000 compared to December 31, 2005. The increase was primarily due to
     the higher sales level, as well as monthly sales within each quarter.


                                      -10-



     Management considers the Company's working capital and long-term
     investments totaling approximately $664,228,000 as of March 31, 2006,
     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. During the quarter ended September 30, 2005, the
     Company repurchased approximately 1,496,000 shares at a cost of
     approximately $25,215,000. During the quarter ended March 31, 2006, the
     Company repurchased approximately 2,804,000 shares at a cost of
     approximately $47,145,000. Approximately 2,870,000 shares remain authorized
     to be repurchased under the plan.

     CRITICAL ACCOUNTING POLICIES:

     The preparation of the Company's consolidated condensed financial
     statements, 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 on-going 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
     are not 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, 2005. Management believes there have been no changes in those
     critical accounting policies, except as noted below.

     Stock-based compensation

     The Company accounts for stock-based compensation in accordance with the
     fair value recognition provisions of SFAS No. 123(R). The Company utilizes
     the Black-Scholes model, which requires the input of subjective
     assumptions. These assumptions include estimating (a) the length of time
     employees will retain their vested stock options before exercising them
     ("expected term"), (b) the volatility of the Company's common stock price
     over the expected term, (c) the number of options that will ultimately not
     complete their vesting requirements ("forfeitures") and (d) expected
     dividends. Changes in the subjective assumptions can materially affect the
     estimate of fair value of stock-based compensation and consequently, the
     related amounts recognized on the consolidated condensed statements of
     operations.

     TRENDS AND DEVELOPMENTS:

     During the first quarter of 2005, the Company negotiated an extension to
     its long-term agreement with General Motors (GM) in the ordinary course of
     the Company's business. Under the extension, the Company 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 competitor under a
     lifetime contract. The new business also includes the GMT360 program, which
     is the mid-size truck/SUV platform that previously did not offer
     auto-dimming mirrors. The new GM programs will be transferred to the
     Company by no later 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(R) feature in its auto-dimming mirrors,
     effective January 1, 2005, in connection with GM's stated plan to make
     their OnStar system standard across their vehicle models over the next
     several years.


                                      -11-



     During the quarter ended September 30, 2005, the Company negotiated an
     extension to its long-term agreement with DaimlerChrysler in the ordinary
     course of the Company's business. Under the extension, the Company will be
     sourced virtually all Mercedes and Chrysler interior and exterior
     auto-dimming rearview mirrors through December 2009.

     The Company currently expects that auto-dimming mirror unit shipments will
     be approximately 10% higher in the second quarter and calendar year of 2006
     compared with 2005. 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 2006 are approximately 15.8 million units for North America, 20.2
     million for Europe and 14.2 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 March 31, 2006, 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, 2005.

     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 or yield 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
     manufacturing yield issues and pressure for select raw material cost
     increases. The automotive industry is experiencing increasing financial and
     production stresses due to continuing pricing pressures, lower domestic
     production levels due to loss of market share, supplier bankruptcies, 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.


                                      -12-



     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.

     NON-GAAP FINANCIAL MEASURE:

     The financial information provided, including earnings, is in accordance
     with GAAP (generally accepted accounting principles). Still, the Company
     believes it is useful to provide non-GAAP earnings to exclude the effect of
     SFAS 123(R). This non-GAAP financial measure allows investors to evaluate
     current performance in relation to historic performance without considering
     this non-cash charge.

     The Company's management uses this non-GAAP information internally to help
     assess performance in the current period versus prior periods. Disclosure
     of non-GAAP earnings to exclude the effect of SFAS 123(R) has economic
     substance because the excluded expenses do not represent current or future
     cash expenditures.

     A reconciliation of non-GAAP earnings, to exclude the effect of SFAS
     123(R), to GAAP earnings can be found in the following financial table. The
     use of non-GAAP earnings is intended to supplement, not to replace,
     presentation of GAAP earnings. Like all non-GAAP financial measures,
     non-GAAP earnings are subject to inherent limitations because all of the
     expenses required by GAAP are not included. The limitations are compensated
     by the fact that non-GAAP earnings are not relied on exclusively, but are
     used to simply supplement GAAP earnings.

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 March 31, 2006, 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 March 31, 2006, 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.

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 expenses on earnings, the ability to
     leverage fixed manufacturing overhead costs, unit shipment growth rates 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 economic recovery in the U.S.
     and in international markets, the pace of automotive production 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.
