(6)  Stock-Based Compensation Plans

     At September 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), "Shares-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 meas-urement principles of APB Opinion No. 25 (Accounting
     for Stock Issued to Employees) and related interpretations, and
     accordingly, recognized no compensation expense for stock option grants in
     net income. Readers should refer to Note 6

          NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONT.)

(6)  Stock-Based Compensation Plans (continued)

     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 third
     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 third quarter and nine months ended September 30, 2006, were
     $1,807,010, $1,266,162, and $.01 per share lower, and $5,276,900,
     $3,513,977 and $.02 per share 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 September 30, 2006, was $91,852. 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 nine
     months ended September 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 nine months ended September
     30, 2006, $214,212 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 $4,089,009 and $12,927,745, respectively, for the third
     quarter and nine months ended September 30, 2006. The actual income tax
     benefit realized from stock option exercises and vested restricted stock
     are $319,057 and $1,223,936, 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
     third quarter and nine months ended September 30, 2005:

     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

(6)  Stock-Based Compensation Plans (continued)

     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
     5,378,608 shares (net of shares from canceled options) under the new plan
     through September 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 Ended   Nine Months Ended

Weighted-average grant-date fair value   $ 3.97    $ 3.99     $ 4.15    $ 5.21


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

     As of September 30, 2006, there was $9,579,726 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.

     third quarter and nine months ended September 30, 2006, and changes during
     the same periods, are presented in the table and narrative below:

     85% of the stock's market price at date of purchase. The weighted average
     fair value of shares sold in 2006 was approximately $13.03.

     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 549,790 shares outstanding as of September 30, 2006,
     and 131,410 shares were granted with a restriction period of five years at
     market prices ranging from $14.00 to $17.09 year to date. As of September
     30, 2006, the Company has unearned stock-based compensation of $5,179,679
     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:

Nine Months Ended       $80,280,623          $81,765,670


(8)  The decrease in common stock during the nine months ended September 30,
     2006, was primarily due the repurchase of 13,972,800 shares for
     approximately $207,364,000, partially offset by the issuance of 1,166,868
     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 and a $0.095 per share cash
     dividend in the third quarter. The third quarter dividend of approximately
     $13,608,000, was declared on August 14, 2006, and was paid on October 20,
     2006.

     automatic-dimming rearview mirrors for the automotive industry, and fire
     protection products for the commercial building industry:

(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.

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

     RESULTS OF OPERATIONS:

     THIRD QUARTER 2006 VERSUS THIRD QUARTER 2005

     Net Sales. Net sales for the third quarter of 2006 increased by
     approximately $3,151,000, or 2%, when compared with the third quarter last
     year. Net sales of the Company's automotive auto-dimming mirrors increased
     by approximately $3,404,000, or 3%, in the third quarter of 2006, when
     compared with the third quarter last year, primarily due to improved
     product mix with additional electronic content in mirrors and an increase
     in auto-dimming mirror unit shipments from approximately 3,198,000 in the
     third quarter of 2005 to 3,210,000 in the current quarter. Unit shipments
     to customers in North America for the current quarter decreased by 8%
     compared with the third quarter of the prior year, primarily due to lower
     production levels at the traditional Big Three. Mirror unit shipments for
     the current quarter to automotive customers outside North America increased
     by 8% compared with the third quarter in 2005, primarily due to increased
     penetration at certain European and Asian automakers. Net sales of the
     Company's fire protection products decreased 4% 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 third quarter of 2005 to 66% in the third quarter
     of 2006, when comparing the current quarter to the same quarter last year,
     primarily reflecting the impact of automotive customer price reductions.
     Stock option expense impacted cost of goods sold by $566,000.

     Operating Expenses. Engineering, research and development expenses for the
     current quarter increased 15% and approximately $1,396,000, when compared
     with the same quarter last year. Excluding stock option expense of
     $605,000, E, R & D expenses increased by 9% when comparing the current
     quarter to the same quarter last year, primarily reflecting additional
     staffing, engineering and testing for new product development, including
     mirrors with additional electronic features. Selling, general and
     administrative expenses increased 14% and approximately $975,000, for the
     current quarter, when compared with the third quarter of 2005. Excluding
     stock option expense of $637,000, S, G & A expenses increased by 5%, when
     comparing the current quarter to the same quarter last year, primarily
     reflecting 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 $614,000 when compared with the third quarter of 2005,
     primarily due to increased interest income due to higher interest rates
     partially offset by lower investable funds, 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 manufacturing deduction, tax-exempt
     investment income and stock option expense.

     Net Income. The Company's net income for the current quarter decreased by
     $3,598,000, or 13%, when compared with the same quarter last year.
     Excluding stock option expense of $1,266,000, the Company's net income
     decreased 8%.

     NINE MONTHS ENDED SEPTEMBER 30, 2006, VERSUS NINE MONTHS ENDED SEPTEMBER
     30, 2005

     Net Sales. Net sales for the nine months ended September 30, 2006,
     increased by $24,536,000, or 6%, when compared with the same period last
     year. Net sales of the Company's automotive auto-dimming mirrors increased
     by $24,599,000, or 6%, as auto-dimming mirror unit shipments increased by
     7% from approximately 9,323,000 in the first nine months of 2005 to
     10,010,000 units in the first nine months of 2006. This increase primarily
     reflected the increased penetration of interior and exterior auto-dimming
     mirrors on 2006 and 2007 model year vehicles. Unit shipments to customers
     in North America increased by 3% as a result of increased unit shipments to
     transplants, partially offset by reduced shipments to domestic automakers
     due to their lower production levels. Mirror shipments to automotive
     customers outside North America increased by 11%, primarily due to
     increased penetration at certain European and Asian automakers. Net sales
     of the Company's fire protection products were flat.


                                      -10-



     Cost of Goods Sold. As a percentage of net sales, cost of goods sold
     increased from 63% in the nine months ended September 30, 2005, to 65% in
     the nine months ended September 30, 2006, when compared to the same period
     last year, primarily reflecting the impact of automotive customer price
     reductions. Stock option expense impacted cost of goods sold by $1,683,000.

     Operating Expenses. For the nine months ended September 30, 2006,
     engineering, research and development expenses increased approximately
     $4,742,000, but remained at 7% of net sales, when compared to the same
     period last year. Excluding stock option expense of $1,881,000, E, R & D
     expenses increased by 11% for the current period versus 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 $2,427,000 for the nine months ended September 30, 2006, but
     remained at 5% of net sales, when compared to the same period last year.
     Excluding stock option expense of $1,712,000, S, G & A expense increased by
     3% versus the same period in the prior year, primarily reflecting the
     continued expansion of the Company's overseas sales offices.

     Total Other Income. Total other income for the nine months ended September
     30, 2006, increased $6,397,000 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 nine months ended September 30, 2006, primarily due to Extra
     Territorial Income Exclusion Act exempted taxable income, domestic
     manufacturing deduction, tax-exempt investment income and stock option
     expense.

     Net Income. The Company's net income for the nine months ended September
     30, 2006, decreased $1,965,000, or 2%, when compared to the same period
     last year, primarily due to stock option expense and automotive customer
     price reductions. Excluding stock option expense of $3,514,000, the
     Company's net income increased by 2%.

     FINANCIAL CONDITION:

     Cash flow from operating activities for the nine months ended September 30,
     2006, increased to $97,517,000, compared to $85,180,000, for the same
     period last year, primarily due to slower growth in accounts receivable.
     Capital expenditures for the nine months ended September 30, 2006,
     increased to $40,406,000, compared to $41,776,000 for the same period last
     year, primarily due to increased purchase of manufacturing equipment.

     The Company has completed the construction of its fourth automotive
     manufacturing facility and a new technical center. The Company has invested
     approximately $38 million for the new facilities during 2004-2006, which
     was funded from its cash and cash equivalents on hand.

     Accounts receivable as of September 30, 2006, increased approximately
     $10,174,000 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 $525,057,000 as of September 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 repurchase of an
     additional eight million shares under the plan. On August 14, 2006, the
     Company announced that the Company's Board of Directors had authorized the
     repurchase of an additional 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


                                      -11-



     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. During the quarter ended September
     30, 2006, the Company repurchased approximately 3,968,000 shares at a cost
     of approximately $55,614,000. Approximately 7,701,000 shares remain
     authorized to be repurchased under the plan.

     CRITICAL ACCOUNTING POLICIES:

     The preparation of the Company's consolidated condensed financial
     statements contained in this report, which have been prepared in accordance
     with accounting principles generally accepted in the Unites States,
     requires management to make estimates and assumptions that affect the
     amounts reported in the financial statements and accompanying notes. On an
     ongoing basis, management evaluates these estimates. Estimates are based on
     historical experience and on various other assumptions that are believed to
     be reasonable under the circumstances, the results of which form the basis
     for making judgments about the carrying values of assets and liabilities
     that 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 have estimated that this
     new business represented incremental auto-dimming mirror units in the range
     of 500,000 on an annualized basis at that time. 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 5% higher in the fourth quarter of calendar year 2006, compared with the
     fourth quarter of 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.


                                      -12-



     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 15.3 million units for North America, 20.3
     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 September 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, 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 6, 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.

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

     The management, with the participation of its principal executive officer
     and principal financial officer, has evaluated the effectiveness, as of
     September 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 of September 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 over financial
     reporting. However, there was no change in the Company's "internal control
     over financial reporting" (as such term is defined in Rules 13a-15(f) and
     15d-15(f) under the Exchange Act) that occurred during the quarter ended
     September 30, 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.

               anti-dilutive effect on earnings, available cash and other
