                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF PRESENTATION

     As permitted by the rules of the Securities and Exchange Commission
     applicable to Quarterly Reports on Form 10-Q, these notes are condensed and
     do not contain all disclosures required by generally accepted accounting
     principles. Reference should be made to the consolidated financial
     statements and related notes included in the Company's Annual Report on
     Form 10-K for the year ended December 31, 2000.

     In the opinion of the management of Cognex Corporation, the accompanying
     consolidated unaudited financial statements contain all adjustments
     (consisting of only normal, recurring adjustments) necessary to present
     fairly the Company's financial position at September 30, 2001, and the
     results of operations for the three and nine months ended September 30,
     2001 and October 1, 2000, and changes in stockholders' equity and cash
     flows for the periods presented.

     The results disclosed in the Consolidated Statements of Income for the
     three and nine months ended September 30, 2001 are not necessarily
     indicative of the results to be expected for the full year.

     Certain amounts reported in prior periods have been reclassified to be
     consistent with the current period's presentation.

Stock options to purchase 2,979,771 and 2,647,362 shares of common stock for the
three-month and nine-month periods ended September 30, 2001, respectively, and
stock options to purchase 1,238,886 and 552,702 shares of common stock for the
three-month and nine-month periods ended October 1, 2000, respectively, were
outstanding but were not included in the calculation of diluted net income per
share because the options' exercise prices were greater than the average market
price of the Company's common stock during those periods. Although these stock
options were antidilutive for the periods presented, they may be dilutive in
future period's calculations.

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

In June 1998, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. The Company
adopted the provisions of SFAS No. 133 effective January 1, 2001. The impact of
adopting SFAS No. 133 was immaterial to the Company.

FOREIGN EXCHANGE RISK MANAGEMENT

The Company enters into forward exchange contracts to hedge a portion of its
intercompany sales of inventory by the US parent to its foreign subsidiary
payable in the foreign subsidiary's local currency. These contracts, which
related primarily to the Japanese Yen and Euro, generally have a time period of
three to six months. Realized and unrealized gains and losses on forward
exchange contracts that do not


                                       6



qualify for hedge accounting are recognized immediately in earnings. The total
gain/loss incurred for transactions that did not qualify as hedges was a
$189,000 gain for the three-month period ended September 30, 2001 and a $175,000
loss for the nine-month period ended September 30, 2001.

The Company uses forward exchange contracts to hedge net investments in certain
of its European subsidiaries, as well as royalty and cost sharing payments due
the parent company. Market value gains and losses on forward exchange contracts
hedging firm commitments are recognized when the hedged transaction occurs.
These contracts, which related primarily to the Euro currency, generally have
a maximum term of two years. Forward exchange contracts receive hedge accounting
on firmly committed transactions when they are designated as a hedge of the
designated currency exposure and are effective in minimizing such exposure.

Forward exchange contracts that qualify for hedge accounting with notional
amounts of $9,700,000, $6,800,000, and $451,000 to exchange Euros for US dollars
were outstanding as of September 30, 2001. For the three-month and nine-month
periods ended September 30, 2001, the Company recorded a cumulative unrealized
loss of $1,192,000 and a cumulative unrealized gain of $694,000, respectively,
related to these foreign exchange contracts in other comprehensive income. These
amounts offset the foreign exchange impact (the hedged transaction), which
resulted in an unrealized foreign exchange gain of $1,216,000 and an unrealized
foreign exchange loss of $550,000 for the same periods.

The market risk exposure from forward exchange contracts is assessed in light of
the underlying currency exposures and is controlled by the initiation of
additional or offsetting foreign exchange contracts.

NEW PRONOUNCEMENTS

In July 2001, the FASB issued SFAS No. 141, "Business Combinations." SFAS No.
141 is effective for all business combinations initiated after June 30, 2001 and
for all business combinations accounted for by the purchase method for which the
date of acquisition is after June 30, 2001. SFAS No. 141 requires that all
business combinations be accounted for under the purchase method and that
certain acquired intangible assets in a business combination be recognized as
assets apart from goodwill. The Company does not expect SFAS No. 141 to have an
impact on the Company's financial statements.

In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible
Assets." SFAS No. 142 is effective for fiscal years beginning after December 15,
2001. SFAS No. 142 requires, among other things, the cessation of the
amortization of goodwill. In addition, the standard includes provisions for the
reclassification of certain existing recognized intangibles as goodwill,
reassessment of the useful lives of existing recognized intangibles,
reclassification of certain intangibles out of previously reported goodwill, and
the identification of reporting units for the purposes of assessing potential
future impairments of goodwill. SFAS No. 142 also requires the Company to
complete a transitional goodwill impairment test six months from the date of
adoption. The Company is currently assessing the impact of this new statement on
its consolidated financial position and results of operations and has not yet
determined the impact of adoption.

In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." SFAS No. 144 is effective for fiscal years
beginning after December 15, 2001. SFAS No. 144 replaces SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of." The standard requires that long-lived assets that are to be
disposed of by sale be measured at the lower of book value or fair value less
cost to sell. Additionally, SFAS No. 144 expands the scope of discontinued
operations to include all components of an entity with operations that can be
distinguished from the rest of the entity and will be eliminated from the
ongoing operations of the entity in a disposal transaction. The Company is
currently assessing the impact of this new statement on its consolidated
financial position and results of operations and has not yet determined the
impact of adoption.

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

     RESULTS OF OPERATIONS

     Revenue for the three-month and nine-month periods ended September 30, 2001
     totaled $33,974,000 and $115,559,000, respectively, compared to $67,960,000
     and $184,642,000 for the same periods in 2000, representing a 50% decrease
     for the three-month period and a 37% decrease for the nine-month period.
     The Company's results continue to be negatively impacted by the worldwide
     slowdown in capital equipment spending by manufacturers in the
     semiconductor and electronics industries. Sales to Original Equipment
     Manufacturers (OEM) customers, most of whom make capital equipment used by
     manufacturers in these industries, decreased $30,687,000, or 72%, from the
     three-month period in 2000 and $58,537,000, or 52%, from the nine-month
     period in 2000. Sales to end-user customers decreased $3,299,000, or 13%,
     from the three-month period in 2000 and $10,546,000, or 15%, from the
     nine-month period in 2000, primarily due to lower demand from customers who
     make electronic products. While revenue decreased in all of the Company's
     worldwide regions from the third quarter of 2000, the most significant
     decrease was in Japan, where most of the Company's core OEM customers are
     located.

     Comparing consecutive quarters, revenue decreased $3,405,000, or 9%, from
     the second quarter of 2001. Sales to OEM customers decreased $4,634,000, or
     28%, from the prior quarter. Sales to end-user customers, however,
     increased $1,229,000, or 6%, primarily due to an increase in sales of the
     Company's surface inspection systems.

     The Company anticipates that its results for the fourth quarter of 2001
     will continue to be negatively impacted by the worldwide slowdown in
     capital equipment spending, as well as the uncertain economic conditions
     that exist today. Accordingly, the Company anticipates that its revenue for
     the fourth quarter of 2001 will be approximately 25% lower than that
     reported in the third quarter of 2001. The Company has limited visibility
     to customer demand beyond the fourth quarter of 2001. Over the past nine
     months, the Company has implemented a number of cost-containment measures
     to more closely align expenses to the lower level of customer demand. These
     measures include salary reductions, elimination of all company bonuses,
     mandatory shutdowns, a reduction in discretionary spending, and most
     recently, the elimination of selected positions. The Company does not
     anticipate the savings from these measures to compensate for the
     substantial decline in revenue, and therefore, expects to report a loss in
     the range of $0.01 to $0.03 per diluted share for the fourth quarter of
     2001.

     Gross profit as a percentage of revenue for the three-month and nine-month
     periods ended September 30, 2001 was 67% and 69%, respectively, compared to
     74% for the same periods in 2000 and 67% for the second quarter of 2001.
     The decrease in gross margin from the prior year was due primarily to the
     impact of the lower sales volume and fixed manufacturing costs, as well as
     a greater percentage of revenue from the sale of services and surface
     inspection systems, both of which carry lower margins than the sale of
     modular vision systems. Gross margin is expected to continue to decrease in
     the fourth quarter of 2001 due to the anticipated lower revenue, as well as
     the continued impact of the sale of services and surface inspection systems
     representing a greater percentage of revenue.

     Research, development, and engineering expenses for the three-month and
     nine-month periods ended September 30, 2001 were $7,583,000 and
     $23,420,000, respectively, compared to $8,265,000 and $23,631,000 for the
     same periods in 2000, representing an 8% decrease for the three-month
     period and a 1% decrease for the nine-month period. Aggregate expenses
     declined slightly from the prior year, as the impact of additional
     headcount to support the Company's continued investment in the research and
     development of new and existing products was offset by savings from
     cost-containment measures, most notably the elimination of all company
     bonuses and a reduction in discretionary spending. Comparing consecutive
     quarters, aggregate expenses were relatively flat, as the Company continued
     its planned product development efforts. Expenses as a percentage of
     revenue were 22% and 20% for the three-




                                       8


     month and nine-month periods in 2001, compared to 12% and 13% for the
     three-month and nine-month periods in 2000. The increase in expenses as a
     percentage of revenue was principally due to the lower revenue base in
     2001. The Company plans to continue its product development efforts, and
     therefore, anticipates that aggregate expenses for the fourth quarter of
     2001 will continue at approximately the level experienced in the third
     quarter.

     Selling, general, and administrative expenses for the three-month and
     nine-month periods ended September 30, 2001 were $14,168,000 and
     $49,047,000, respectively, compared to $16,143,000 and $43,313,000 for the
     same periods in 2000, representing a 12% decrease for the three-month
     period and a 13% increase for the nine-month period. Aggregate expenses
     decreased for the three-month period, as the impact of additional headcount
     to support the Company's expanding worldwide operations and grow its
     end-user business was offset by savings from cost-containment measures,
     most notably the elimination of all company bonuses and a reduction in
     discretionary spending. The impact of the cost- containment measures,
     however, was not enough to offset the impact of the additional headcount in
     the first half of 2001, and as a result, aggregate expenses increased for
     the nine-month period. Comparing consecutive quarters, aggregate expenses
     decreased $2,273,000, or 14%, due to the impact of the cost-containment
     measures implemented during the year. Expenses as a percentage of revenue
     were 42% for the three-month and nine-month periods in 2001, compared to
     24% and 23% for the three-month and nine-month periods in 2000. The
     increase in expenses as a percentage of revenue was principally due to the
     lower revenue base in 2001. The Company expects to continue to realize
     benefits from its cost-containment measures, and therefore, anticipates
     that aggregate expenses for the fourth quarter of 2001 will be lower than
     the level experienced in the third quarter.

     Amortization of goodwill for the three-month and nine-month periods ended
     September 30, 2001 was $773,000 and $2,328,000, respectively, compared to
     $555,000 and $1,199,000 for the same periods in 2000. The increase in
     amortization expense was due to additional goodwill associated with the
     acquisitions completed during 2000.

     Investment income for the three-month and nine-month periods ended
     September 30, 2001 was $2,834,000 and $8,318,000 compared to $2,624,000 and
     $6,931,000 for the same periods in 2000, representing an 8% and 20%
     increase, respectively. The increase in investment income was due to a
     combination of a higher average invested balance in 2001 and higher average
     interest rates on the Company's portfolio of investments, which consists
     primarily of debt securities.

     The Company's effective tax rate was 32% for all periods presented.

     LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash requirements during the nine-month period ended
     September 30, 2001 were met through cash generated from operations. Cash
     and investments increased $12,124,000 from December 31, 2000 primarily as a
     result of $20,527,000 of cash generated from operations, partially offset
     by $3,991,000 of capital expenditures, principally for computer hardware.

     On December 12, 2000, the Company's Board of Directors authorized the
     repurchase of up to $100,000,000 of the Company's common stock. As of
     September 30, 2001, the Company had not repurchased any shares under this
     program.

     The Company believes that its existing cash and investments balance,
     together with cash generated from operations, will be sufficient to meet
     the Company's planned working capital, investing, and financing
     requirements through 2001, including the Company's stock repurchase program
     and potential business acquisitions.

     NEW PRONOUNCEMENTS

     In July 2001, the FASB issued SFAS No. 141, "Business Combinations." SFAS
     No. 141 is effective for all business combinations initiated after June 30,
     2001 and for all business combinations accounted for by the purchase method
     for which the date of acquisition is after June 30, 2001. SFAS No. 141
     requires that all business combinations be accounted for under the purchase
     method and that certain acquired intangible assets in a business
     combination be recognized as assets apart from goodwill. The Company does
     not expect SFAS No. 141 to have an impact on the Company's financial
     statements.

     In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible
     Assets." SFAS No. 142 is effective for fiscal years beginning after
     December 15, 2001. SFAS No. 142 requires, among other things, the cessation
     of the amortization of goodwill. In addition, the standard includes
     provisions for the reclassification of certain existing recognized
     intangibles as goodwill, reassessment of the useful lives of existing
     recognized intangibles, reclassification of certain intangibles out of
     previously reported goodwill, and the identification of reporting units for
     the purposes of assessing potential future impairments of goodwill. SFAS
     No. 142 also requires the Company to complete a transitional goodwill
     impairment test six months from the date of adoption. The Company is
     currently assessing the impact of this new statement on its consolidated
     financial position and results of operations and has not yet determined the
     impact of adoption.

     In October 2001, the FASB issued SFAS No. 144, "Accounting for the
     Impairment or Disposal of Long-Lived Assets." SFAS No. 144 is effective for
     fiscal years beginning after December 15, 2001. SFAS No. 144 replaces SFAS
     No. 121, "Accounting for the Impairment of Long-Lived Assets and for
     Long-Lived Assets to Be Disposed Of." The standard requires that long-lived
     assets that are to be disposed of by sale be measured at the lower of book
     value or fair value less cost to sell. Additionally, SFAS No. 144 expands
     the scope of discontinued operations to include all components of an entity
     with operations that can be distinguished from the rest of the entity and
     will be eliminated from the ongoing operations of the entity in a disposal
     transaction. The Company is currently assessing the impact of this new
     statement on its consolidated financial position and results of operations
     and has not yet determined the impact of adoption.

     FORWARD-LOOKING STATEMENTS

     Certain statements made in this report, as well as oral statements made by
     the Company from time to time, which are prefaced with words such as
     "expects," "anticipates," "believes," "projects," "intends," "plans," and
     similar words and other statements of similar sense, are forward-looking
     statements. These statements are based on the Company's current
     expectations and estimates as to prospective events and circumstances,
     which may or may not be in the Company's control and as to which there can
     be no firm assurances given. These forward-looking statements, like any
     other forward-looking statements, involve risks and uncertainties that
     could cause actual results to differ materially from those projected or
     anticipated. Such risks and uncertainties include (1) the loss of, or a
     significant curtailment of purchases by, any one or more principal
     customers; (2) the cyclicality of the semiconductor and electronics
     industries; (3) the Company's continued ability to achieve significant
     international revenue; (4) the capital spending trends by manufacturing
     companies; (5) the inability to protect the Company's proprietary
     technology and intellectual property; (6) the inability to attract or
     retain skilled employees; (7) the technological obsolescence of current
     products and the inability to develop new products; (8) the inability to
     respond to competitive technology and pricing pressures; and (9) the
     reliance upon certain sole source suppliers to manufacture or deliver
     critical components of the Company's products. The foregoing list should
     not be construed as exhaustive and the Company disclaims any obligation to
     subsequently revise forward-looking statements to reflect events or
     circumstances after the date of such statements or to reflect the
     occurrence of anticipated or unanticipated events. Further discussions of
     risk factors are also available in the Company's registration statements
     filed with the Securities and Exchange Commission. The Company wishes to
     caution readers not to place undue reliance upon any such forward-looking
     statements, which speak only as of the date made.
