(6)  Stock-Based Compensation Plans

     At June 30, 2006, the Company had two stock option plans, a restricted plan
     and an employee stock purchase plan, which are described more fully below.
     Effective January 1, 2006, the Company adopted Statement of Financial
     Accounting Standards 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,


                                       -5-



     and accordingly, recognized 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 second
     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 second quarter and six months ended June 30, 2006, were $1,749,795,
     $1,324,894, and $.01 lower, and $3,469,890, $2,247,815 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 as of June 30, 2006, was
     $91,611. 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 six months
     ended June 30, 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 six months ended June 30, 2006, $176,803
     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 $2,497,767 and $8,838,736, respectively, for the second
     quarter and six months ended June 30, 2006. The actual income tax benefit
     realized from stock option exercises and vested restricted stock are
     $209,568 and $904,879, respectively, for the same periods.

     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
     second quarter and six months ended June 30, 2005:

   Diluted - pro forma                 $       .16    $        .22


     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


                                       -6-



     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
     5,001,353 shares (net of shares from canceled options) under the new plan
     through June 30, 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    Six Months Ended

Weighted-average grant-date fair value   $ 3.90   $ 6.17   $ 4.27    $ 5.81


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

     As of June 30, 2006, there was $9,374,634 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.

     A summary of the status of the Company's employee stock option plan for the
     second quarter and six months ended June 30, 2006, and changes during the
     same periods, are presented in the table and narrative below:

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 384,248
     shares under the new plan through June 30, 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 $13.31.

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 533,990 shares outstanding as of June 30, 2006, and
     95,610 shares were granted with a restriction period of five years at a
     market prices ranging from $14.00 to $17.09 year to date. As of June 30,
     2006, the Company has unearned stock-based compensation of $5,168,728
     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:



                   June 30, 2006   June 30, 2005
                   -------------   -------------

Six Months Ended    $53,731,609     $49,922,035


(8)  The decrease in common stock during the six months ended June 30, 2006, was
     primarily due to the repurchase of 10,004,629 shares for approximately
     $151,750,000, partially offset by the issuance of 789,299 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 and second quarters. The second quarter dividend of
     approximately $13,215,000, was declared on May 25, 2006, and was paid on
     July 21, 2006.

(10) In July 2006, the Financial Accounting Standards Board (FASB) issued
     Interpretation No. 48, "Accounting for Uncertainty in Income Taxes." This
     interpretation clarifies the accounting for uncertainty in income taxes
     recognized in an enterprise's financial statements in accordance with FASB
     statement No. 109, "Accounting for Income Taxes." Interpretation No. 48
     prescribes a recognition threshold and measurement attribute for the
     financial statement recognition and measurement of a tax position taken or
     expected to be taken in a tax return. This Interpretation also provides
     guidance on derecognition, classification, interest and penalties,
     accounting in interim periods, disclosure and transition. This
     Interpretation is effective for fiscal years beginning after December 15,
     2006. The adoption of Interpretation No. 48 is not expected to have any
     significant effect on the Company's consolidated financial position or
     results of operations.

     GENTEX CORPORATION AND SUBSIDIARIES

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

          RESULTS OF OPERATIONS:

          SECOND QUARTER 2006 VERSUS SECOND QUARTER 2005

          Net Sales. Net sales for the second quarter of 2006 increased by
          approximately $10,007,000, or 8%, when compared with the second
          quarter last year. Net sales of the Company's automotive auto-dimming
          mirrors increased by approximately $9,925,000, or 8%, in the second
          quarter of 2006, when compared with the second quarter last year,
          primarily due to a 10% increase in auto-dimming mirror unit shipments
          from approximately 3,095,000 in the second quarter of 2005 to
          3,408,000 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 10%
          compared with the second quarter of the prior year, primarily due to
          the takeover business at General Motors previously disclosed. Mirror
          unit shipments for the current quarter to automotive customers outside
          North America increased by 10% compared with the second quarter in
          2005, primarily due to increased penetration at certain European and
          Asian automakers. Net sales of the Company's fire protection products
          increased 1% for the current quarter versus the same quarter of last
          year.

          Cost of Goods Sold. As a percentage of net sales, cost of goods sold
          increased from 63% in the second quarter of 2005 to 64% in the second
          quarter of 2006. This percentage increase primarily reflected the
          impact of automotive customer price reductions.

          Operating Expenses. Engineering, research and development expenses for
          the current quarter increased 13% and approximately $1,164,000, when
          compared with the same quarter last year, primarily reflecting stock
          option expensing, additional staffing, engineering and testing for new
          product development, including mirrors with additional electronic
          features, and stock option expensing. Excluding stock option expense
          of $619,000, E, R & D expenses increased by 6% when comparing the
          current quarter to the same quarter last year. Selling, general and
          administrative expenses increased 7% and approximately $502,000, for
          the current quarter, when compared with the second quarter of 2005.
          This increased expense primarily reflected stock option expensing.
          Excluding stock option expense of $556,000, S, G & A expenses
          decreased by 1% when comparing the current quarter to the same quarter
          last year, primarily due to decreased state taxes.

          Total Other Income. Total other income for the current quarter
          increased by approximately $2,418,000 when compared with the second
          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 deduction,
          tax-exempt investment income and stock option expense.

          Net Income. The Company's net income for the current quarter increased
          by $1,195,000, or 5%, when compared with the same quarter last year.
          Excluding stock option expense of $1,325,000, the Company's net income
          increased 10%.

          SIX MONTHS ENDED JUNE 30, 2006, VERSUS SIX MONTHS ENDED JUNE 30, 2005

          Net Sales. Net sales for the six months ended June 30, 2006, increased
          by $21,386,000, or 8%, when compared with the same period last year.
          Net sales of the Company's automotive auto-dimming mirrors increased
          by $21,195,000, or 9%, as auto-dimming mirror shipments increased by
          11% from approximately 6,125,000 in the first six months of 2005 to
          6,800,000 units in the first six months of 2006. This increase
          primarily reflected the increased penetration of interior auto-dimming
          mirrors on 2006 model year vehicles. Unit shipments to customers in
          North America increased by 9%, primarily due to the takeover business
          at General Motors. Mirror shipments to automotive customers outside
          North America increased by 13%, primarily due to increased penetration
          at certain European and Asian automakers. Net sales of the Company's
          fire protection products increased 2%.


                                      -11-



          Cost of Goods Sold. As a percentage of net sales, cost of goods sold
          increased from 62% in the six months ended June 30, 2005, to 65% in
          the six months ended June 30, 2006, primarily reflecting automotive
          customer price reductions and stock option expense. 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, 2006,
          engineering, research and development expenses increased approximately
          $3,346,000, and increased from 6% to 7% of net sales, when compared to
          the same period last year, primarily due to stock option expense and
          additional staffing, engineering and testing for new product
          development, including mirrors with additional electronic features.
          Excluding stock option expense of $1,277,000, E, R & D expenses
          increased by 6% for the current period versus the same period last
          year. Selling, general and administrative expenses increased
          approximately $1,453,000 for the six months ended June 30, 2006, but
          remained at 5% of net sales, when compared to the same period last
          year, primarily reflecting stock option expense and the continued
          expansion of the Company's overseas offices. Excluding stock option
          expense of $1,076,000, S, G & A expense increased by 3% versus the
          same period in the prior year.

          Total Other Income. Other income for the six months ended June 30,
          2006, increased $5,783,000 when compared to the same period last year,
          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 six months ended June 30, 2006, primarily due to Extra
          Territorial Income Exclusion Act exempted taxable income, domestic
          production deduction, tax-exempt investment income and stock option
          expense.

          Net Income. The Company's net income for the six months ended June 30,
          2006, increased $1,633,000, or 3%, when compared to the same period
          last year, primarily due to the increased net sales. Excluding stock
          option expense of $2,248,000, the Company's net income increased by
          7%.

          FINANCIAL CONDITION:

          Cash flow from operating activities for the six months ended June 30,
          2006, slightly increased to $71,090,000, compared to $70,680,000, for
          the same period last year, primarily due to an increase in net income.
          Capital expenditures for the six months ended June 30, 2006, increased
          to $30,181,000, compared to $28,729,000 for the same period last year,
          including the new facility construction.

          The Company has completed the construction of its fourth automotive
          manufacturing facility and a new technical center will be completed in
          the summer of 2006. The Company has invested approximately $35-40
          million for the new facilities during 2004-2006, which has been funded
          from its cash and cash equivalents on hand.

          Accounts receivable as of June 30, 2006, increased approximately
          $9,584,000 compared to December 31, 2005. The increase was primarily
          due to the higher sales level, as well as monthly sales within each
          quarter.

          Management considers the Company's working capital and long-term
          investments totaling approximately $563,628,000 as of June 30, 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. On
          May 16, 2006, the Company announced that the Company's Board of
          Directors had authorized the repurchased of an additional eight
          million shares under the 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. During the quarter ended June 30, 2006, the
          Company repurchased approximately 7,201,000 shares at a cost of
          approximately $104,604,000. Approximately 3,669,000 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.

          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 0-5% higher in the third quarter and 5-10%
          higher in the calendar year of 2006, compared with the same periods in
          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, 20.3 million for Europe and 14.3 million for Japan and
          Korea.


                                      -13-



          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, 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.

          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.

          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.


                                      -14-



     ITEM 4. CONTROLS AND PROCEDURES

          The management, with the participation of its principal executive
          officer and principal financial officer, has evaluated the
          effectiveness, as of June 30, 2006, 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 June 30, 2006, were effective to provide reasonable
          assurance that 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 to provide reasonable assurance that 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 for
          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 June 30, 2006, 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
          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.
