             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)



1.    BASIS OF PRESENTATION

      The unaudited consolidated financial statements of Brooks Automation, Inc.
      and its subsidiaries ("Brooks" or the "Company") included herein have been
      prepared in accordance with generally accepted accounting principles. In
      the opinion of management, all material adjustments which are of a normal
      and recurring nature necessary for a fair presentation of the results for
      the periods presented have been reflected.

      The accompanying financial information should be read in conjunction with
      the consolidated financial statements and notes thereto contained in the
      Company's Annual Report on Form 10-K, filed with the United States
      Securities and Exchange Commission for the year ended September 30, 2001.

      On December 15, 2001, the Company acquired Fab Air Control ("Fab Air"), a
      Massachusetts company that develops exhaust control and airflow management
      systems for the semiconductor industry. On December 13, 2001, the Company
      acquired the Automation Systems Group of Zygo Corporation ("Zygo Group").
      The Zygo Group, located in Florida, is a manufacturer of reticle
      automation systems, including reticle sorters, reticle macro inspection
      systems and reticle handling solutions for the semiconductor industry. On
      October 9, 2001, the Company acquired 90% of the capital stock of Tec-Sem
      A.G., a Swiss company ("Tec-Sem"). Tec-Sem is a leading manufacturer of
      bare reticle stockers, tool buffers and batch transfer systems for the
      semiconductor industry. On October 5, 2001, the Company acquired
      substantially all of the assets of General Precision, Inc. ("GPI"). GPI,
      located in Valencia, California, is a leading supplier of high-end
      environmental solutions for the semiconductor industry. These transactions
      were recorded using the purchase method of accounting in accordance with
      Financial Accounting Standards Board Statement No. 141, "Business
      Combinations" ("FAS 141"). Accordingly, the Company's Consolidated
      Statements of Operations and of Cash Flows for the three months ended
      December 31, 2001, include the results of these acquired entities for the
      periods subsequent to their respective acquisitions.

      On July 12, 2001, the Company acquired Progressive Technologies, Inc.
      ("PTI") in a transaction accounted for as a pooling of interests initiated
      prior to June 30, 2001. Accordingly, the Company's consolidated financial
      statements and notes thereto have been restated to include the financial
      position and results of operations of PTI for all periods prior to the
      acquisition. Prior to its acquisition by the Company, PTI's fiscal
      year-end was December 31.

      The Company made several acquisitions during fiscal year 2001 which were
      accounted for using the purchase method of accounting in accordance with
      Accounting Principles Board Opinion No. 16, "Business Combinations" ("APB
      16"): KLA-Tencor, Inc.'s e-Diagnostics product line infrastructure
      ("e-Diagnostics") on June 26, 2001; CCS Technology, Inc. ("CCST") on June
      25, 2001, SimCon N.V. ("SimCon") on May 15, 2001; SEMY Engineering, Inc.
      ("SEMY") on February 16, 2001 and substantially all of the assets of a
      software and service distributor in Japan ("ASI-Japan"). The Company's
      Consolidated Statements of Operations and of Cash Flows include the
      results of these entities for the periods subsequent to their respective
      acquisitions.

      Certain amounts in previously issued financial statements have been
      reclassified to conform to current presentation.


                                                                               6

                             BROOKS AUTOMATION, INC.
       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) - Continued


      On October 23, 2001, the Company entered into an Agreement and Plan of
      Merger (the "Merger Agreement") to acquire PRI Automation, Inc. ("PRI").
      Pursuant to the Merger Agreement and subject to the terms and conditions
      contained therein, holders of each share of PRI common stock will receive
      0.52 shares of the Company's common stock.

      The merger, which is expected to close in late March or April of 2002, is
      contingent upon the fulfillment of certain conditions as provided in the
      Merger Agreement including, but not limited to, all required regulatory
      approvals, the approval of the merger by the stockholders of PRI and the
      approval of the issuance of the Company's common stock in the merger by
      the stockholders of the Company.

      PRI supplies advanced factory automation systems, software, and services
      that optimize the productivity of semiconductor and precision electronics
      manufacturers, as well as OEM process tool manufacturers.

      In July 2001, the Financial Accounting Standards Board ("FASB") issued
      Statements of Financial Accounting Standards No. 141, "Business
      Combinations" ("FAS 141") and No. 142, "Goodwill and Other Intangible
      Assets" ("FAS 142"). FAS 141 requires that all business combinations be
      accounted for under the purchase method only and that certain acquired
      intangible assets in a business combination be recognized as assets apart
      from goodwill. FAS 142 requires that ratable amortization of goodwill be
      replaced with periodic tests of the goodwill's impairment and that
      intangible assets other than goodwill be amortized over their useful
      lives. FAS 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 before June 30, 2001.
      The provisions of FAS 142 will be effective for fiscal years beginning
      after December 15, 2001; however, the Company elected to early adopt the
      provisions effective October 1, 2001. The Company will perform an annual
      impairment test of goodwill, required under FAS 142, as at the end of each
      fiscal year.

      In October 2001, the FASB issued Statement of Financial Accounting
      Standards No. 144, "Accounting for the Impairment or Disposal of
      Long-Lived Assets" ("FAS 144"). The objectives of FAS 144 are to address
      significant issues relating to the implementation of FASB Statement No.
      121 ("Accounting for the Impairment of Long-Lived Assets and for
      Long-Lived Assets to Be Disposed Of" ("FAS 121") and to develop a single
      accounting model, based on the framework established in FAS 121, for
      long-lived assets to be disposed of by sale, whether previously held and
      used or newly acquired. FAS 144 is effective for financial statements
      issued for fiscal years beginning after December 15, 2001, and generally,
      its provisions are to be applied prospectively. The adoption of this
      standard is not expected to have a material impact on the Company's
      consolidated financial statements.

      CRITICAL ACCOUNTING POLICIES AND ESTIMATES

      The preparation of consolidated financial statements requires the Company
      to make estimates and judgments that affect the reported amounts of
      assets, liabilities, revenues and expenses, and related disclosure of
      contingent assets and liabilities. On an on-going basis, the Company
      evaluates its estimates, including those related to product returns, bad
      debts, inventories, intangible assets, income taxes, warranty obligations,
      excess component order cancellation costs, restructuring and contingencies
      and litigation. The Company bases its estimates 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. Actual results may differ from these
      estimates under different assumptions or conditions.

      The Company believes the following critical accounting policies affect its
      more significant judgments and estimates used in the preparation of its
      consolidated financial statements.

      The Company has made a number of acquisitions and identified significant
      intangible assets and goodwill. Intangible assets are amortized over their
      estimated useful life and goodwill is subject to annual impairment
      testing. The carrying value and realization of these assets is dependent
      upon estimates of future earnings and benefits that the Company expects to
      generate. If the Company's expectations of future results are
      significantly diminished, intangible assets and goodwill may be impaired
      and the resulting charge to operations may be material.

      The Company maintains allowances for doubtful accounts for estimated
      losses resulting from the inability of its customers to make required
      payments. If the financial condition of the Company's customers were to
      deteriorate, resulting in an impairment of their ability to make payments,
      additional allowances may be required.

      The Company provides for the estimated cost of product warranties at the
      time revenue is recognized. While the Company engages in extensive product
      quality programs and processes, including actively monitoring and
      evaluating the quality of its component suppliers, the Company's warranty
      obligation is affected by product failure rates and material usage and
      service delivery costs incurred in correcting a product failure. Should
      actual product failure rates, material usage or service delivery costs
      differ from the Company's estimates, revisions to the estimated warranty
      liability would be required.

      The Company writes down its inventory for estimated obsolescence or
      unmarketable inventory equal to the difference between the cost of
      inventory and the estimated market value based upon assumptions about
      future demand and market conditions. If actual market conditions are less
      favorable than those projected by management, additional inventory
      write-downs may be required.

      The Company records a valuation allowance to reduce its deferred tax
      assets to the amount that is more likely than not to be realized. While
      the Company has considered future taxable income and ongoing prudent and
      feasible tax planning strategies in assessing the need for the valuation
      allowance, in the event the Company were to determine that it would be
      able to realize its deferred tax assets in the future in excess of its net
      recorded amount, an adjustment to the deferred tax asset would increase
      income in the period such determination was made. Likewise, should the
      Company determine that it would not be able to realize all or part of its
      net deferred tax asset in the future, an adjustment to the deferred tax
      asset would be charged to income in the period such determination was
      made.

2.    BUSINESS ACQUISITIONS

      POOLING OF INTERESTS TRANSACTION

      On July 12, 2001, the Company acquired PTI in exchange for 715,004 shares
      of the Company's common stock. The acquisition has been accounted for as a
      pooling of interests. PTI is engaged in the development, production and
      distribution of airflow regulation systems for clean room and process
      equipment in the semiconductor industry.

      The accompanying consolidated financial statements and notes thereto for
      the three months ended December 31, 2000 have been restated to include the
      financial position and results of operations for PTI.

      PURCHASE TRANSACTIONS

      Fab Air

      On December 15, 2001, the Company acquired Fab Air, a Massachusetts
      company that develops exhaust control and airflow management systems for
      the semiconductor industry. In consideration, the Company paid $1.1
      million of cash and incurred $0.3 million of transaction costs. The
      transaction was accounted for as a purchase of assets in accordance with
      FAS 141. The excess of purchase price over fair value of net tangible
      assets acquired of $1.4 million has been recorded as completed technology,
      with an estimated useful life of three years, and will be amortized using
      the straight-line method. Pro forma results of operations are not
      presented as the amounts are not material compared to the Company's
      historical results.

      Zygo Group

      On December 13, 2001, the Company acquired the Zygo Group, located in
      Florida. The Zygo Group is a manufacturer of reticle automation systems,
      including reticle sorters, reticle macro inspection systems, and reticle
      handling solutions for the semiconductor industry. In consideration, the
      Company paid $11.4 million of cash. The transaction was accounted for as a
      purchase of assets in accordance with FAS 141.


      A portion of the excess of purchase price over fair value of net assets
      acquired was allocated on a preliminary basis to identifiable intangible
      assets, each of which the Company estimates to have a useful life of three
      years. Accordingly, the Company is amortizing these intangible assets over
      three years, using the straight-line method. The balance of the excess
      purchase price was recorded as goodwill. In accordance with FAS 142, the
      Company will not amortize the goodwill, but will instead test for
      impairment at least annually. Finalization of the allocation of excess of
      purchase price over the fair value of net assets acquired to identifiable
      intangible assets and goodwill will be made after completion of the
      analysis of their fair values, which the Company expects to occur in the
      second quarter of fiscal 2002. The Company believes it has sufficient
      information to finalize the purchase price allocation but requires
      additional time to complete the analysis. A change in the allocation
      between the acquired identifiable intangible assets and goodwill of
      $1,000,000 would result in a change in annual amortization expense of
      approximately $333,000. An increase in the weighted average useful life of
      the acquired identifiable intangible assets from three years to four years
      would result in a decrease in annual amortization expense of approximately
      $335,000. A decrease in the weighted average useful life of the acquired
      identifiable intangible assets from three years to two years would result
      in an increase in annual amortization expense of approximately $669,000.

      Tec-Sem

      On October 9, 2001, the Company acquired Tec-Sem, a leading manufacturer
      of bare reticle stockers, tool buffers and batch transfer systems for the
      semiconductor industry. In consideration, the Company paid $12.9 million
      of cash and issued 131,750 shares of Brooks common stock with a market
      value of $4.3 million at the time of issuance, subject to post-closing
      adjustments, which the Company expects to complete in accordance with the
      procedures defined in the terms of the acquisition agreement. The
      acquisition agreement establishes a procedure for post-closing adjustments
      in which the net assets of Tec-Sem are determined at a point in time prior
      to the closing and compared with the net assets at closing. To the extent
      that there is a decrease in the net value of the assets, the purchase
      price will be reduced on a dollar for dollar basis. The parties are in
      the process of completing this analysis, which is scheduled for completion
      under the acquisition agreement within 60 days of the closing of the
      transaction. The Company also granted 25,000 shares of fully issued common
      stock with a market value of $0.8 million at the time of issuance, to
      certain key non-owner employees of Tec-Sem, which were accounted for as
      additional purchase price, since the issuance of the shares is not related
      to any continuing employee obligations to the Company. The fair value of
      the shares issued was determined utilizing the average closing price of
      the Company's common stock over a period of two days before and the day
      of the acquisition.


      A portion of the excess of purchase price over fair value of net tangible
      assets acquired was allocated on a preliminary basis to identifiable
      intangible assets, each of which the Company estimates will have a useful
      life of three years. Accordingly, the Company is amortizing these
      intangible assets over three years, using the straight-line method. The
      balance of the excess was recorded as goodwill. In accordance with FAS
      142, the Company will not amortize the goodwill, but will instead test for
      impairment at lease annually. Finalization of the allocation of excess of
      purchase price over the fair value of net liabilities assumed to
      identifiable intangible assets and goodwill will be made after completion
      of the analysis of their fair values. Pro forma results of operations are
      not presented as the amounts are not material compared to the Company's
      historical results. A summary of the transaction is as follows (in

      GPI


      On October 5, 2001, the Company acquired substantially all of the assets
      of GPI in exchange for 850,000 shares of Brooks common stock, with a
      market value of $26.2 million at the time of issuance, subject to
      post-closing adjustments, and $0.2 million of cash. The Company expects to
      complete any post-closing adjustments in accordance with the procedures
      defined in the terms of the acquisition agreement. The acquisition
      agreement establishes a procedure for post-closing adjustments in which
      the net assets of GPI are determined at a point in time prior to the
      closing and compared with the net assets at closing. To the extent that
      there is a decrease in the net value of the assets, the purchase price
      will be reduced on a dollar for dollar basis. The parties are in the
      process of completing this analysis, which is scheduled for completion
      under the acquisition agreement within 134 days of the closing of the
      transaction. GPI, located in Valencia, California, is a leading supplier
      of high-end environmental solutions for the semiconductor industry. The
      fair value of the shares issued was determined utilizing the average
      closing price of the Company's common stock over a period of two days
      before and the day of the acquisition.


      A portion of the excess of purchase price over fair value of net assets
      acquired was allocated on a preliminary basis to identifiable intangible
      assets, each of which the Company estimates will have a useful life of
      three years. Accordingly, the Company is amortizing these intangible
      assets over three years, using the straight-line method. The balance of
      the excess was recorded as goodwill. In accordance with FAS 142, the
      Company will not amortize the goodwill, but will instead test for
      impairment at least annually. Finalization of the allocation of the excess
      of purchase price over fair value of net assets acquired to identifiable
      intangible assets and goodwill will be made upon completion of the
      analysis of their fair values. A summary of the transaction is as follows
      (in thousands):

3.    GOODWILL AND INTANGIBLE ASSETS


      The Company has elected to early adopt the provisions of FAS 142 effective
      October 1, 2001. Accordingly, the Company ceased the ratable amortization
      of goodwill on that date. The Company recorded amortization expense of
      $3.7 million and $6.0 million for its amortizable intangible assets for
      the three months ended December 31, 2001 and 2000, respectively. Estimated
      future amortization expense on the intangible assets recorded by the
      Company as of December 31, 2001 is as follows (in thousands):

        2006                        $  2,360



      The amortization of goodwill excluded from the Company's results of
      operations for the three months ended December 31, 2001 as a result
      of the adoption of FAS 142 totaled $7.7 million.

      Options to purchase and assumed conversions totaling approximately 4.3
      million shares of common stock were excluded from the computation of
      diluted loss per share for the three months ended December 31, 2001, as
      their effect would be anti-dilutive. Options to purchase approximately 2.3
      million shares of common stock were excluded from the computation of
      diluted earnings per share for the three months ended December 31, 2000,
      as their effect would be anti-dilutive. However, these options and
      conversions could become dilutive in future periods.


5.    COMPREHENSIVE INCOME (LOSS)

      Comprehensive income (loss) for the Company is computed as the sum of net
      income (loss) and the change in the cumulative translation adjustment,
      which is the only component of the Company's accumulated other
      comprehensive loss. The Company's comprehensive loss for the three months
      ended December 31, 2001 was $11,415,000. Comprehensive income was
      $4,666,000 for the three months ended December 31, 2000.

6.    SEGMENT AND GEOGRAPHIC INFORMATION

      The Company has three reportable segments: tool automation systems,
      factory interface solutions and factory automation solutions. The tool
      automation systems segment provides a full complement of semiconductor
      wafer and flat panel display substrate handling systems, products and
      components and products for data storage. The factory interface solutions
      segment provides hardware and software solutions, including
      minienvironments and automated transfer mechanisms, to isolate the
      semiconductor wafer from the production environment. The factory
      automation segment provides software products for the semiconductor
      manufacturing execution system ("MES") market, including consulting and
      software customization.

      The Company evaluates performance and allocates resources based on
      revenues and operating income (loss). Operating income (loss) for each
      segment includes selling, general and administrative expenses directly
      attributable to the segment. Amortization of acquired intangible assets
      and acquisition-related charges are excluded from the segments' operating
      income (loss). The Company's non-allocable overhead costs, which include
      corporate general and administrative expenses, are allocated between the
      segments based upon segment revenues. Segment assets exclude deferred
      taxes, acquired intangible assets, goodwill, all assets of the Company's
      Securities Corporation and investments in subsidiaries. The Company's
      Securities Corporation holds the Company's investments in marketable
      securities and is fully consolidated.

      Financial information for the Company's business segments is as follows
      (in thousands):

10.   CONTINGENCY

      There has been substantial litigation regarding patent and other
      intellectual property rights in the semiconductor and related industries.
      In 1992, the Company received notice from a third party alleging
      infringements of such party's patent rights by certain of the Company's
      products. The Company believes the patents claimed may be invalid. In the
      event of litigation with respect to this claim, the Company is prepared to
      vigorously defend its position. However, because patent litigation can be
      extremely expensive and time consuming, the Company may seek to obtain a
      license to one or more of the disputed patents. Based upon currently
      available information, the Company would only do so if such license fees
      would not be material to the Company's consolidated financial statements.
      Currently, the Company does not believe it is probable that the future
      events related to this threatened matter would have an adverse effect on
      the Company's business.


                                                                              17

OVERVIEW

Brooks Automation, Inc. ("Brooks" or the "Company") is a leading supplier of
integrated tool and factory automation solutions for the global semiconductor
and related industries, such as the data storage and flat panel display
manufacturing industries. Brooks has distinguished itself as a technology and
market leader, particularly in the demanding cluster-tool vacuum-processing
environment and in integrated factory automation software applications. The
Company's offerings have grown from individual robots used to transfer
semiconductor wafers in advanced production equipment to fully integrated
automation solutions that control the flow of resources in the factory from
process tools to factory scheduling and dispatching. In 1998, the Company began
an aggressive program of investment and acquisition. By the close of fiscal year
2000, Brooks had emerged as one of the leading suppliers of factory and tool
automation solutions for semiconductor and original equipment manufacturers.

Many of the Company's customers purchase the Company's vacuum transfer robots
and other modules before purchasing the Company's vacuum central wafer handling
systems. The Company believes that once a customer has selected the Company's
products for a process tool, the customer is likely to rely on those products
for the life of that process tool model, which can be in excess of five years.
Conversely, losing a bid for a manufacturing execution system ("MES") does not
preclude the Company from securing optimization products to fit with a
competitor's MES.

The Company's foreign revenues are generally denominated in United States
dollars. Accordingly, foreign currency fluctuations have not had a significant
impact on the comparison of the results of operations for the periods presented.
The costs and expenses of the Company's international subsidiaries are generally
denominated in currencies other than the United States dollar. However, since
the functional currency of the Company's international subsidiaries is the local
currency, foreign currency translation adjustments are reflected as a component
of stockholders' equity under the caption "Accumulated other comprehensive
income (loss)". To the extent that the Company expands its international
operations or changes its pricing practices to denominate prices in foreign
currencies, the Company will be exposed to increased risk of currency
fluctuation.

these acquired entities for the periods subsequent to their respective
acquisitions.

On July 12, 2001, the Company acquired Progressive Technologies, Inc. ("PTI") in
a transaction accounted for as a pooling of interests initiated prior to June
30, 2001. Accordingly, the Company's consolidated financial statements and notes
thereto have been restated to include the financial position and results of
operations of PTI for all periods prior to the acquisition. Prior to its
acquisition by the Company, PTI's fiscal year-end was December 31.

The Company made several acquisitions during fiscal year 2001 which were
accounted for using the purchase method of accounting in accordance with
Accounting Principles Board Opinion No. 16, "Business Combinations" ("APB 16"):
KLA-Tencor, Inc.'s e-Diagnostics product line infrastructure ("e-Diagnostics")

Cash Flows include the results of these entities for the periods subsequent to
their respective acquisitions.

RECENT DEVELOPMENTS

On October 23, 2001, the Company entered into an Agreement and Plan of Merger
(the "Merger Agreement") to acquire PRI Automation, Inc. ("PRI"). Pursuant to
the Merger Agreement and subject to the terms and conditions contained
therein, holders of each share of PRI common stock will receive 0.52 shares of
the Company's common stock.

The merger, which is expected to close in the third quarter of fiscal 2002, is
contingent upon the fulfillment of certain conditions as provided in the Merger
Agreement including, but not limited to, all required regulatory approvals, the
approval of the merger by the stockholders of PRI and the approval of the
issuance of the Company's common stock in the merger by the stockholders of the
Company.

RESULTS OF OPERATIONS

The Company's business is significantly dependent on capital expenditures by
semiconductor manufacturers and OEM's, which are, in turn, dependent on the
current and anticipated market demand for semiconductors. The Company's revenues
grew substantially in fiscal 2000 and the first half of fiscal 2001, due in
large part to high levels of capital expenditures of semiconductor
manufacturers. Demand for semiconductors is cyclical and has historically
experienced periodic downturns. The semiconductor industry is currently
experiencing such a downturn, which began to impact the Company in the third
quarter of fiscal 2001, affecting both revenues and gross margins. As a result
of this downturn, the Company anticipates continued lower shipments of its
products in fiscal 2002, compared to fiscal 2001. During fiscal 2001, the
Company had taken selective cost reduction actions in many areas of its business
in response to this ongoing downturn. These cost management initiatives included
reductions to headcount, salary and wage reductions and reduced spending.
Although the Company continues to take a proactive approach to cost management
in response to this downturn, it will continue to invest in those areas which it
believes are important to the long-term growth of the Company, such as its
infrastructure, customer support and new products.

Three Months Ended December 31, 2001, Compared to Three Months Ended December
31, 2000

The Company reported a net loss of $7.7 million for the three months ended
December 31, 2001, compared to net income of $5.5 million in the same period of
the prior year. The results for the three months ended December 31, 2001 include
$3.6 million of amortization of acquired intangible assets and $0.1 million of
acquisition-related and restructuring costs. The results for the prior year
period include $5.7 million of amortization of acquired intangible assets. There
were no acquisition-related and restructuring costs recorded in the three months
ended December 31, 2000.

Revenues

The Company reported revenues of $61.5 million in the three months ended
December 31, 2001, compared to $111.4 million in the same prior year period. The
overall decrease in revenues is principally attributable to the current downturn
in the semiconductor industry, partially offset by approximately $6 million in
incremental revenue from acquisitions.

The Company's tool automation systems segment reported revenues of $20.4 million
in the three months ended December 31, 2001, a decrease of 64.7% from the same
prior year period. The decrease is attributable to the current downturn in the
semiconductor industry, partially offset by approximately $1 million of
incremental revenues from acquisitions. The Company's factory interface
solutions segment reported a decrease in revenues of 37.1%, to $17.8 million, in
the three month period ended December 31, 2001, compared to the three months
ended December 30, 2000. The decrease is attributable to the current downturn in
the semiconductor industry, partially offset by approximately $3 million of
incremental revenues from acquisitions. The Company's factory automation
solutions segment reported revenues of $23.2 million in the three months ended
December 31, 2001, a decrease of 7.8% from the same prior year period. The
decrease resulting from the downturn in the semiconductor industry was partially
offset by approximately $2 million of incremental revenues from acquisitions.


                                                                              20

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS - Continued



Product revenues decreased $49.1 million, to $42.7 million, in the three months
ended December 31, 2001, compared to $91.8 million in the three months ended
December 31, 2000. The decrease is attributable to the downturn currently
affecting the semiconductor industry, partially offset by incremental revenues
of approximately $5 million from acquisitions.

Service revenues for the three months ended December 31, 2001 were $18.7
million, a decrease of $0.8 million, or 4.2%, from the three months ended
December 31, 2000. The decrease is primarily attributable to the current
industry downturn, partially offset by incremental revenues from acquisitions
approximating $1 million.

Foreign revenues were $37.3 million, or 60.6% of revenues, and $50.4 million, or
45.2% of revenues, in the three month periods ended December 31, 2001 and 2000,
respectively. The Company's expanded global presence through its recent
acquisitions and expanded sales and marketing activities, combined with reduced
sales in the United States due to the current industry downturn, has contributed
to the increase in international revenues as a percentage of total revenues. The
Company expects that foreign revenues will continue to account for a significant
portion of total revenues. However, the Company cannot guarantee that foreign
revenues will remain a major component of the Company's total revenues.

Gross Margin


Gross margin decreased to 39.2% for the three months ended December 31, 2001,
compared to 45.4% for the same prior year period. The overall decrease in gross
margin is primarily attributable to lower revenue levels which are a result of
the current downturn affecting the semiconductor industry. These lower revenue
levels impact cost absorption, exerting downward pressure on gross margins. In
the three months ended on December 31, 2001, the Company provided $482,000 for
excess and obsolete inventories. The charge is an estimate of reserve
requirements based on an analysis the Company performs on a periodic basis. As a
result of the continuing downturn in the semiconductor industry, on-hand
inventory levels continue to exceed expected demand. Excluding the impact of
this provision, the Company's gross margin was 40.0% for the period.


The Company's tool automation systems segment gross margin decreased to 31.8%
for the three months ended December 31, 2001, from 38.2% in the comparable prior
year period. The change is the net result of the impact of the industry
downturn, partially offset by changes in product mix. Gross margin for the
Company's factory interface solutions segment was 26.3% for the three months
ended December 31, 2001, compared to 41.5% in the same prior year period. The
decrease is primarily the result of changes in product and services mix,
combined with the current downturn in the semiconductor industry. The Company's
factory automation solutions segment gross margin decreased to 55.6% in the
three months ended December 31, 2001, from 66.6% in the comparable year period.
The decrease is primarily attributable to changes in product and services mix;
specifically, a decrease in higher margin license revenues partially offset by
an increase in lower margin service revenues.

Gross margin on product revenues was 42.9% for the three months ended December
31, 2001, a decrease from 48.7% in the same prior year period. The decrease is
primarily attributable to the current semiconductor industry downturn and the
resulting downward pressure on sales volume, pricing and margins. Gross margin
on service revenues was 31.0% for the three months ended December 31, 2001, a
slight increase from 30.2% for the three months ended December 31, 2000.

Research and Development

Research and development expenses for the three months ended December 31, 2001
were $14.1 million, an increase of $0.5 million, compared to $13.6 million in
the three months ended December 31, 2000.  Research

and development expenses increased as a percentage of revenues in the three
months ended December 31, 2001, to 23.0%, compared to 12.2% in the same prior
year period. The increase in these expenditures as a percentage of revenues for
this three month period is primarily attributable to the lower sales volumes
resulting from the downturn currently affecting the semiconductor industry. The
increase in absolute spending is associated with the Company's recent
acquisitions, which accounted for approximately $2 million of research and
development expense in the three months ended December 31, 2001. The Company
plans to continue to invest in research and development to enhance existing and
develop new tool and factory hardware and software automation solutions for the
semiconductor, data storage and flat panel display manufacturing industries.

Selling, General and Administrative

Selling, general and administrative expenses were $18.9 million for the three
months ended December 31, 2001, a decrease of $4.9 million, compared to $23.8
million in the same prior year period. However, selling, general and
administrative expenses increased as a percentage of revenues in the three
months ended December 31, 2001, to 30.8%, from 21.3% in the comparable prior
year period. The increase in these expenditures as a percentage of revenues for
the three months ended December 31, 2001, is primarily attributable to the lower
sales volumes resulting from the downturn currently affecting the semiconductor
industry. The decrease in absolute spending reflects the impact of the Company's
ongoing cost reduction actions and synergies from recent acquisitions. These
acquisitions accounted for approximately $2 million of the Company's selling,
general and administrative expense in the three months ended December 31, 2001.

Amortization of Acquired Intangible Assets

Amortization expense for acquired intangible assets totaled $3.6 million in the
three months ended December 31, 2001, and relates to the identifiable intangible
assets recorded by the Company for the acquisitions of GPI, Tec-Sem and the Zygo
Group in the current fiscal year, the e-Diagnostics product line, CCST, SimCon,
SEMY and ASI-Japan in the prior fiscal year, ASC, ASI and MiTeX in fiscal 2000,
Infab, Domain and Hanyon in fiscal 1999 and Irvine Optical's acquisition of a
corporation in March 1997. Amortization expense for acquired intangible assets,
including goodwill, was $5.7 million in the three months ended December 31,
2000. The Company has elected to early adopt the provisions of FAS 142.
Accordingly, effective October 1, 2001, the Company ceased the amortization of
goodwill. The reduction in amortization of acquired intangible assets for the
three months ended December 31, 2001, compared to the same prior year period
reflects this change.

Acquisition-related Charges

The Company reported $0.1 million of acquisition-related charges for the three
months ended December 31, 2001, primarily legal and accounting fees incurred for
the acquisition of PTI. The Company did not record any acquisition-related and
restructuring charges in the three months ended December 31, 2000. The activity
related to the Company's acquisition-related and restructuring liabilities
during the three months ended December 31, 2001, is below (in thousands):

Interest Income and Expense


Interest income decreased by $1.1 million, to $2.8 million, in the three months
ended December 31, 2001, compared to the same prior year period, primarily as a
result of lower interest rates coupled with slightly lower balances available
for investment. Interest expense of $2.6 million for the three months ended
December 31, 2001, is primarily comprised of $2.3 million related to the
Company's Convertible Subordinated Notes and imputed interest expense on the
notes payable related to the Company's recent acquisitions of the e-Diagnostics
product line and SimCon, aggregating $0.2 million. Interest expense of $0.2
million in the prior year period is primarily related to the Company's note
payable to Daifuku America in connection with the acquisition of ASC and ASI.
This note was paid in full on January 5, 2001.


Income Tax Provision (Benefit)

The Company recorded a net income tax benefit of $4.1 million for the three
months ended December 31, 2001 and income tax expense of $5.0 million in the
comparable prior year period. The tax benefit is attributable to the loss in the
current quarter. The prior year period tax provision is attributable to federal,
state and foreign income taxes. Federal and state taxes have been reduced for
net operating losses, research and development and foreign tax credits and an
extraterritorial income benefit which replaced the foreign sales corporation
benefit.

The Company has recorded a deferred tax asset of $40.8 million. Realization is
dependent on generating sufficient taxable income prior to expiration of loss
carryforwards, which will expire at various dates through 2022. Although
realization is not assured, the Company believes that it is more likely than not
that all of the deferred tax assets will be realized. The Company has considered
both positive and negative available evidence in its determination that the
deferred tax asset will be realized. While current economic conditions,
including a current quarter book loss, provide some evidence that the deferred
tax assets may not be fully realized, the cyclical nature of the industry sector
and recent historical experience of income provide objective positive evidence
that the deferred tax assets are recoverable. The Company believes that its
efforts to right-size the business in the fourth quarter of fiscal 2001 and the
recent acquisitions in the first quarter of the current fiscal year will be
important factors in achieving future profitability. The amount of the deferred
tax asset considered realizable, however, could be reduced in the near term if
estimates of the future taxable income during the carryforward period are
reduced. The Company estimates that the significant net reversing temporary
difference will be available for use through 2022. Additionally, other
significant reversing temporary differences will be available for use through
2036. Therefore, the Company estimates that its annual future taxable income
must average $2.3 million per year during the carryforward period to fully
realize the benefit of the net deferred tax asset.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $130.2 million at December 31, 2001, a decrease
of $30.1 million from September 30, 2001. This decrease in cash and cash
equivalents is primarily due to $26.8 million of payments for the Company's
recent acquisitions, including $12.9 million relating to Tec-Sem and $11.6
million relating to the Zygo Group.

Cash provided by operations was $1.6 million for the three months ended December
31, 2001, and is primarily attributable to an adjustment to the Company's net
loss for depreciation and amortization of $7.5 million, coupled with a decrease
in accounts receivable of $15.4 million. These amounts were partially offset by
decreases in accounts payable and accrued expenses and other current liabilities
of $6.9 million and $10.5 million, respectively.


The Company's days sales outstanding ("DSO") increased for the three months
ended December 31, 2001 compared to the same prior year period. The decrease in
revenues for the three months ended December 31, 2001 was disproportionate to
the decrease in accounts receivable, thereby adversely impacting DSO.
Additionally, the decrease in revenues was also disproportionate to the
decrease in inventories, adversely impacting days sales in inventory.


Cash used in investing activities was $31.3 million for the three months ended
December 31, 2001, and is principally comprised of $12.9 million for the
acquisition of Tec-Sem, net of cash acquired, $11.6 million for the acquisition
of the Zygo Group, net of cash acquired, $2.3 million for other acquisitions,
net of cash acquired, $4.5 million used for capital additions and $13.2 million
invested in marketable securities. These expenditures were partially offset by
sale of $10.2 million of the Company's investments in marketable securities.

Cash provided by financing activities was $0.1 million, and is comprised of $0.6
million of cash from the exercise of options to purchase the Company's common
stock, partially offset by $0.5 million for the payment of long-term debt.

While the Company has no significant capital commitments, as it expands its
product offerings, the Company anticipates that it will continue to make capital
expenditures to support its business and improve its computer systems
infrastructure. In addition, assuming none of the Convertible Subordinated Notes
are converted into common stock, the Company expects to expend approximately $8
million per year on interest related to these notes. The Company may also use
its resources to acquire companies, technologies or products that complement the
business of the Company.

The Company terminated its $30.0 million unsecured revolving credit facility and
replaced it with a $10.0 million uncommitted demand promissory note facility
with ABN AMRO Bank N.V. ("ABN AMRO") on May 2, 2000. The Company transferred all
of its outstanding letters of credit, totaling approximately $1.1 million, to
the new facility. ABN AMRO is not obligated to extend loans or issue letters of
credit under this new facility. At December 31, 2001, $1.1 million of the
facility was in use, all of it for letters of credit.

The Company believes that its existing resources will be adequate to fund the
Company's currently planned working capital and capital expenditure requirements
for at least the next twelve months. The sufficiency of the Company's resources
to fund its needs for capital is subject to known and unknown risks,
uncertainties and other factors which may have a material adverse effect on the
Company's business, including, without limitation, the factors discussed under
"Factors That May Affect Future Results."

RECENTLY ENACTED ACCOUNTING PRONOUNCEMENTS

In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statements of Financial Accounting Standards No. 141, "Business Combinations"
("FAS 141") and No. 142, "Goodwill and Other Intangible Assets" ("FAS 142"). FAS
141 requires that all business combinations be accounted for under the purchase
method only and that certain acquired intangible assets in a business
combination be recognized as assets apart from goodwill. FAS 142 requires that
ratable amortization of goodwill be replaced with periodic tests of the
goodwill's impairment and that intangible assets other than goodwill be
amortized over their useful lives. FAS 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 before
June 30, 2001. The provisions of FAS 142 will be effective for fiscal years
beginning after December 15, 2001; however, the Company elected to early adopt
the provisions effective October 1, 2001. The Company will perform an annual
impairment test of goodwill, required under FAS 142, as at the end of each
fiscal year.

In October 2001, the FASB issued Statement of Financial Accounting Standards No.
144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("FAS
144"). The objectives of FAS 144 are to address significant issues relating to
the implementation of FASB Statement No. 121 ("Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("FAS 121") and
to develop a single accounting model, based on the framework established in FAS
121, for long-lived assets to be disposed of by sale, whether previously held
and used or newly acquired. FAS 144 is effective for financial statements issued
for fiscal years beginning after December 15, 2001, and generally, its
provisions are to be applied prospectively. The adoption of this standard is not
expected to have a material impact on the Company's consolidated financial
statements.

FACTORS THAT MAY AFFECT FUTURE RESULTS

   From time to time, information provided by Brooks or statements made by its
employees may contain forward-looking information that involves substantial
known and unknown risks and uncertainties such as those described below that
could cause actual results to differ materially from targets or projected
results.

   You should carefully consider the risks described below and the other
information in this report before deciding to invest in shares of our common
stock. These are the risks and uncertainties we believe are most important for

which we currently deem immaterial or which are similar to those faced by other
companies in our industry or business in general, may also impair our business
operations. If any of the following risks or uncertainties actually occur, our
business, financial condition and operating results would likely suffer. In that
event, the market price of our common stock could decline and you could lose all
or part of the money you paid to buy our common stock.

                    RISK FACTORS RELATING TO BROOKS' INDUSTRY

THE CYCLICAL DEMAND OF SEMICONDUCTOR MANUFACTURERS AFFECTS BROOKS' OPERATING
RESULTS AND THE ONGOING DOWNTURN IN THE INDUSTRY COULD SERIOUSLY HARM BROOKS'
OPERATING RESULTS.

   Brooks' business is significantly dependent on capital expenditures by
semiconductor manufacturers. The level of semiconductor manufacturers' capital
expenditures is dependent on the current and anticipated market demand for
semiconductors. The semiconductor industry is highly cyclical and is currently
experiencing a downturn. Brooks anticipates the downturn will continue during
the next few quarters. Despite these industry conditions, Brooks plans to
continue to invest in those areas which Brooks believes are important to its
long-term growth, such as its infrastructure and information technology system,
customer support, supply chain management and new products. As a result,
consistent with its experience in downturns in the past, Brooks believes the
current industry downturn will lead to reduced revenues for it and may cause it
to incur losses.

INDUSTRY CONSOLIDATION AND OUTSOURCING OF THE MANUFACTURE OF SEMICONDUCTORS TO
FOUNDRIES COULD REDUCE THE NUMBER OF AVAILABLE CUSTOMERS.

   The substantial expense of building or expanding a semiconductor fabrication
facility is leading increasing numbers of semiconductor companies to contract
with foundries, which manufacture semiconductors designed by others. As
manufacturing is shifted to foundries, the number of Brooks' potential customers
could decrease, which would increase its dependence on its remaining customers.
Recently, consolidation within the semiconductor manufacturing industry has
increased. If semiconductor manufacturing is consolidated into a small number of
foundries and other large companies, Brooks' failure to win any significant bid
to supply equipment to those customers could seriously harm its reputation and
materially and adversely affect its revenue and operating results.


                                                                              26

                   RISK FACTORS RELATING TO BROOKS' OPERATIONS

BROOKS' SALES VOLUME SUBSTANTIALLY DEPENDS ON THE SALES VOLUME OF BROOKS'
ORIGINAL EQUIPMENT MANUFACTURER CUSTOMERS AND ON INVESTMENT IN MAJOR CAPITAL
EXPANSION PROGRAMS, RETROFITS AND UPGRADES BY END USER SEMICONDUCTOR
MANUFACTURING COMPANIES.

   Brooks sells a majority of its tool automation products to original equipment
manufacturers that incorporate Brooks' products into their equipment. Therefore,
Brooks' revenues depend on the ability of these customers to develop, market and
sell their equipment in a timely, cost-effective manner. Approximately 40% of
Brooks' total revenue for the quarter ended December 31, 2001 and approximately
56% of Brooks' total revenue in fiscal 2001 comes from sales to original
equipment manufacturers.

   Brooks also generates significant revenues from large orders from
semiconductor manufacturing companies that build new plants or invest in major
automation retrofits and upgrades. Brooks' revenues depend, in part, on
continued capital investment by semiconductor manufacturing companies.
Approximately 60% of Brooks' total revenue for the quarter ended December 31,
2001 and approximately 44% of Brooks' total revenue in fiscal 2001 comes from
sales to semiconductor manufacturing companies.

BROOKS RELIES ON A RELATIVELY LIMITED NUMBER OF CUSTOMERS FOR A LARGE PORTION OF
ITS REVENUES AND BUSINESS.


   Brooks receives a significant portion of its revenues in each fiscal period
from a relatively limited number of customers. The loss of one or more of these
major customers, or a decrease in orders by one or more customers, could
adversely affect Brooks' revenue, business and reputation. Sales to Brooks' ten
largest customers accounted for approximately 39% of total revenues in the
quarter ended December 31, 2001, 37% of total revenues in fiscal 2001 and 40% of
total revenues in fiscal 2000.


DELAYS IN OR CANCELLATION OF SHIPMENTS OF A FEW OF BROOKS' LARGE ORDERS COULD
SUBSTANTIALLY DECREASE ITS REVENUES OR REDUCE ITS STOCK PRICE.

   Historically, a substantial portion of Brooks' quarterly and annual revenues
has come from sales of a small number of large orders. Some of Brooks' products
have high selling prices compared to Brooks' other products. As a result, the
timing of when Brooks recognizes revenue from one of these large orders can have
a significant impact on its total revenues and operating results for a
particular period and reduce its stock price because its sales in that fiscal
period could fall significantly below the expectations of financial analysts and
investors. This could cause the value of its common stock to fall. Brooks'
operating results could be harmed if a small number of large orders are canceled
or rescheduled by customers or cannot be filled due to delays in manufacturing,
testing, shipping or product acceptance.

DEMAND FOR BROOKS' PRODUCTS FLUCTUATES RAPIDLY AND UNPREDICTABLY, WHICH MAKES IT
DIFFICULT TO MANAGE ITS BUSINESS EFFICIENTLY AND CAN REDUCE ITS GROSS MARGINS
AND PROFITABILITY.

   Brooks' expense levels are based in part on its expectations for future
demand. Many expenses, particularly those relating to capital equipment and
manufacturing overhead, are relatively fixed. The rapid and unpredictable shifts
in demand for Brooks' products make it difficult to plan manufacturing capacity
and business operations efficiently. If demand is significantly below
expectations, Brooks may be unable to rapidly reduce these fixed costs, which
can diminish gross margins and cause losses. A sudden downturn may also leave
Brooks with excess inventory, which may be rendered obsolete as products evolve
during the downturn


                                                                              27

                             BROOKS AUTOMATION, INC.
           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS - Continued



and demand shifts to newer products. Brooks' ability to reduce expenses is
further constrained because it must continue to invest in research and
development to maintain its competitive position and to maintain service and
support for its existing global customer base. Conversely, in sudden upturns,
Brooks sometimes incurs significant expenses to rapidly expedite delivery of
components, procure scarce components and outsource additional manufacturing
processes. These expenses could reduce its gross margins and overall
profitability. Any of these results could seriously harm Brooks' business.

BROOKS' LENGTHY SALES CYCLE REQUIRES IT TO INCUR SIGNIFICANT EXPENSES WITH NO
ASSURANCE THAT BROOKS WILL GENERATE REVENUE.

   Brooks' tool automation products are generally incorporated into original
equipment manufacturer equipment at the design stage. To obtain new business
from its original equipment manufacturer customers, Brooks must develop products
for selection by a potential customer at the design stage. This often requires
Brooks to make significant expenditures without any assurance of success. The
original equipment manufacturer's design decisions often precede the generation
of volume sales, if any, by a year or more. Brooks cannot guarantee that the
equipment manufactured by its original equipment manufacturing customers will be
commercially successful. If Brooks or its original equipment manufacturing
customers fails to develop and introduce new products successfully and in a
timely manner, Brooks' business and financial results will suffer.

   Brooks also must complete successfully a costly evaluation and proposal
process before Brooks can achieve volume sales of Brooks factory automation
software to customers. These undertakings are major decisions for most
prospective customers and typically involve significant capital commitments and
lengthy evaluation and approval processes. Brooks cannot guarantee that it will
continue to satisfy evaluations by its end-user customers.

BROOKS' OPERATING RESULTS WOULD BE HARMED IF ONE OF ITS KEY SUPPLIERS FAILS TO
DELIVER COMPONENTS FOR BROOKS' PRODUCTS.

   Brooks currently obtains many of its components on an as needed, purchase
order basis. Generally, Brooks does not have any long-term supply contracts with
its vendors and believes many of its vendors have been taking cost containment
measures in response to the industry downturn. When demand for semiconductor
manufacturing equipment increases, Brooks' suppliers face significant challenges
in delivering components on a timely basis. Brooks' inability to obtain
components in required quantities or of acceptable quality could result in
significant delays or reductions in product shipments. This could create
customer dissatisfaction, cause lost revenue and otherwise materially and
adversely affect Brooks' operating results. Delays on Brooks' part could also
cause it to incur contractual penalties for late delivery.

BROOKS MAY EXPERIENCE DELAYS AND TECHNICAL DIFFICULTIES IN NEW PRODUCT
INTRODUCTIONS AND MANUFACTURING, WHICH CAN ADVERSELY AFFECT ITS REVENUES, GROSS
MARGINS AND NET INCOME.

   Because Brooks' systems are complex, there can be a significant lag between
the time Brooks introduces a system and the time it begins to produce that
system in volume. As technology in the semiconductor industry becomes more
sophisticated, Brooks is finding it increasingly difficult to design and
integrate complex technologies into its systems, to procure adequate supplies of
specialized components, to train its technical and manufacturing personnel and
to make timely transitions to high-volume manufacturing. Many customers also
require customized systems, which compound these difficulties. Brooks sometimes
incurs substantial


                                                                              28

                             BROOKS AUTOMATION, INC.
           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS - Continued



unanticipated costs to ensure that its new products function properly and
reliably early in their life cycle. These costs could include greater than
expected installation and support costs or increased materials costs as a result
of expedited changes. Brooks may not be able to pass these costs on to its
customers. In addition, Brooks has experienced, and may continue to experience,
difficulties in both low and high volume manufacturing. Any of these results
could seriously harm Brooks' business.

   Moreover, on occasion Brooks has failed to meet its customers' delivery or
performance criteria, and as a result Brooks incurred late delivery penalties
and had higher warranty and service costs. These failures could continue and
could also cause Brooks to lose business from those customers and suffer
long-term damage to its reputation.

BROOKS MAY BE UNABLE TO RECRUIT AND RETAIN NECESSARY PERSONNEL BECAUSE OF
INTENSE COMPETITION FOR HIGHLY SKILLED PERSONNEL.

   Brooks needs to retain a substantial number of employees with technical
backgrounds for both its hardware and software engineering, manufacturing, sales
and support staffs. The market for these employees is intensively competitive,
and Brooks has occasionally experienced delays in hiring qualified personnel.
Due to the cyclical nature of the demand for its products and the current
downturn in the semiconductor market, Brooks recently reduced its workforce as a
cost reduction measure. If the semiconductor market experiences an upturn,
Brooks may need to rebuild its workforce. Due to the competitive nature of the
labor markets in which Brooks operates, this type of employment cycle increases
Brooks' risk of being unable to retain and recruit key personnel. Brooks'
inability to recruit, retain and train adequate numbers of qualified personnel
on a timely basis could adversely affect its ability to develop, manufacture,
install and support its products and may result in lost revenue and market share
if customers seek alternative solutions.

BROOKS' INTERNATIONAL BUSINESS OPERATIONS EXPOSE IT TO A NUMBER OF DIFFICULTIES
IN COORDINATING ITS ACTIVITIES ABROAD AND IN DEALING WITH MULTIPLE REGULATORY
ENVIRONMENTS.

   Sales to customers outside North America accounted for approximately 61% of
Brooks' total revenues in the quarter ended December 31, 2001, 50% in fiscal
2001, 48% in fiscal 2000 and 43% in fiscal 1999. Brooks anticipates that
international sales will continue to account for a significant portion of its
revenues. Many of Brooks' vendors are located in foreign countries. As a result
of its international business operations, Brooks is subject to various risks,
including:

   -  difficulties in staffing and managing operations in multiple locations in
      many countries;

   -  difficulties in managing distributors, representatives and third party
      systems integrators;

   -  challenges presented by collecting trade accounts receivable in foreign
      jurisdictions;

   -  longer sales-cycles;

   -  possible adverse tax consequences;

   -  fewer legal protections for intellectual property;

   -  governmental currency controls and restrictions on repatriation of
      earnings;

   -  changes in various regulatory requirements;

   -  political and economic changes and disruptions; and

   -  export/import controls and tariff regulations.


                                                                              29

   To support its international customers, Brooks maintains locations in several
countries, including Belgium, Canada, China, Germany, Japan, Malaysia,
Singapore, South Korea, Switzerland, Taiwan and the United Kingdom. Brooks
cannot guarantee that it will be able to manage these operations effectively.
Brooks cannot assure you that its investment in these international operations
will enable it to compete successfully in international markets or to meet the
service and support needs of its customers, some of whom are located in
countries where Brooks has no infrastructure.

   Although Brooks' international sales are primarily denominated in U.S.
dollars, changes in currency exchange rates can make it more difficult for
Brooks to compete with foreign manufacturers on price. If Brooks' international
sales increase relative to its total revenues, these factors could have a more
pronounced effect on Brooks' operating results.

BROOKS MUST CONTINUALLY IMPROVE ITS TECHNOLOGY TO REMAIN COMPETITIVE.

   Technology changes rapidly in the semiconductor, data storage and flat panel
display manufacturing industries. Brooks believes its success depends in part
upon its ability to enhance its existing products and to develop and market new
products to meet customer needs, even in industry downturns. For example, as the
semiconductor industry transitions from 200mm manufacturing technology to 300mm
technology, Brooks believes it is important to its future success to develop and
sell new products that are compatible with 300mm technology. If competitors
introduce new technologies or new products, Brooks' sales could decline and its
existing products could lose market acceptance. Brooks cannot guarantee that it
will identify and adjust to changing market conditions or succeed in introducing
commercially rewarding products or product enhancements. The success of Brooks'
product development and introduction depends on a number of factors, including:

   -  accurately identifying and defining new market opportunities and products;

   -  completing and introducing new product designs in a timely manner;

   -  market acceptance of Brooks' products and its customers' products;

   -  timely and efficient software development, testing and process;

   -  timely and efficient implementation of manufacturing and assembly
      processes;

   -  product performance in the field;

   -  development of a comprehensive, integrated product strategy; and

   -  efficient implementation and installation and technical support services.

   Because Brooks must commit resources to product development well in advance
of sales, its product development decisions must anticipate technological
advances by leading semiconductor manufacturers. Brooks may not succeed in that
effort. Its inability to select, develop, manufacture and market new products or
enhance its existing products could cause it to lose its competitive position
and could seriously harm its business.


                                                                              30

BROOKS FACES SIGNIFICANT COMPETITION WHICH COULD RESULT IN DECREASED DEMAND FOR
BROOKS' PRODUCTS OR SERVICES.

   The markets for Brooks' products are intensely competitive. Brooks may be
unable to compete successfully. Brooks believes the primary competitive factors
in the tool automation systems segment are throughput, reliability,
contamination control, accuracy and price/performance. Brooks believes that its
primary competition in the tool automation market is from integrated original
equipment manufacturers that satisfy their semiconductor and flat panel display
handling needs internally rather than by purchasing systems or modules from an
independent supplier like Brooks. Many of these original equipment manufacturers
have substantially greater resources than Brooks does. Applied Materials, Inc.,
the leading process equipment original equipment manufacturer, develops and
manufactures its own central wafer handling systems and modules. Brooks may not
be successful in selling its products to original equipment manufacturers that
internally satisfy their wafer or substrate handling needs, regardless of the
performance or the price of Brooks products. Moreover, integrated original
equipment manufacturers may begin to commercialize their handling capabilities
and become Brooks competitors.

   Brooks believes that the primary competitive factors in the end user
semiconductor manufacturer market for factory automation and process control
solutions are product functionality, price/performance, ease of use, ease of
integration and installation, hardware and software platform compatibility,
costs to support and maintain, vendor reputation and financial stability. The
relative importance of these competitive factors may change over time. Brooks
directly competes in this market with various competitors, including Applied
Materials-Consilium, IBM, Si-view, Compaq, TRW, Camstar and numerous small,
independent software companies. Brooks also competes with the in-house software
staffs of semiconductor manufacturers like NEC, Texas Instruments and Intel.
Most of those manufacturers have substantially greater resources than Brooks
does.

   Brooks believes that the primary competitive factors in the factory interface
market are technical and technological capabilities, reliability,
price/performance, ease of integration and global sales and support capability.
In this market, Brooks competes directly with Asyst, Rorze, Fortrend, Newport,
TOK, Yasakawa and Hirata. Some of these competitors have substantial financial
resources and extensive engineering, manufacturing and marketing capabilities.

MUCH OF BROOKS' SUCCESS AND VALUE LIES IN ITS OWNERSHIP AND USE OF INTELLECTUAL
PROPERTY, AND BROOKS' FAILURE TO PROTECT THAT PROPERTY COULD ADVERSELY AFFECT
ITS FUTURE OPERATIONS.

   Brooks' ability to compete is heavily affected by its ability to protect its
intellectual property. Brooks relies primarily on trade secret laws,
confidentiality procedures, patents, copyrights, trademarks and licensing
arrangements to protect its intellectual property. The steps Brooks has taken to
protect its technology may be inadequate. Existing trade secret, trademark and
copyright laws offer only limited protection. Brooks' patents could be
invalidated or circumvented. The laws of certain foreign countries in which
Brooks products are or may be developed, manufactured or sold may not fully
protect Brooks' products. This may make the possibility of piracy of Brooks'
technology and products more likely. Brooks cannot guarantee that the steps
Brooks has taken to protect its intellectual property will be adequate to
prevent misappropriation of its technology. Other companies could independently
develop similar or superior technology without violating Brooks' proprietary


                                                                              31

rights.  There has been substantial litigation regarding patent and other
intellectual property rights in semiconductor-related industries. Brooks may
engage in litigation to:

   -  enforce its patents;

   -  protect its trade secrets or know-how;

   -  defend itself against claims alleging it infringes the rights of others;
      or

   -  determine the scope and validity of the patents or intellectual property
      rights of others.

   Any litigation could result in substantial cost to Brooks and divert the
attention of Brooks' management, which could harm its operating results and its
future operations. A party making such a claim could secure a judgment against
Brooks that requires it to pay substantial damages. A judgment could also
include an injunction or other court order that could prevent Brooks from
selling its products. Any of these events could seriously harm Brooks' business.

BROOKS' OPERATIONS COULD INFRINGE ON THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS.

   Particular aspects of Brooks' technology could be found to infringe on the
intellectual property rights or patents of others. Other companies may hold or
obtain patents on inventions or may otherwise claim proprietary rights to
technology necessary to Brooks' business. Brooks cannot predict the extent to
which it may be required to seek licenses or alter its products so that they no
longer infringe the rights of others. Brooks cannot guarantee that the terms of
any licenses it may be required to seek will be reasonable. Similarly, changing
Brooks' products or processes to avoid infringing the rights of others may be
costly or impractical or could detract from the value of its products.

BROOKS' BUSINESS MAY BE HARMED BY INFRINGEMENT CLAIMS OF GENERAL SIGNAL OR
APPLIED MATERIALS.


   Brooks received notice from General Signal Corporation twice in 1992 and once
in 1994, alleging certain of Brooks' tool automation systems products that
Brooks sells to semiconductor process tool manufacturers infringed General
Signal's patent rights. The notification advised Brooks that General Signal was
attempting to enforce its rights to those patents in litigation against Applied
Materials, and that, at the conclusion of that litigation, General Signal
intended to enforce its rights against us and others. According to a press
release issued by Applied Materials in November 1997, Applied Materials settled
its litigation with General Signal by acquiring ownership of five General Signal
patents. Although not verified by Brooks, these five patents would appear to be
the patents referred to by General Signal in its prior notice to Brooks. Applied
Materials has not contacted Brooks regarding these patents. Brooks cannot
guarantee that it would prevail in any litigation by Applied Materials seeking
damages or expenses from Brooks or to enjoin Brooks from selling its products on
the basis of the alleged patent infringement, or that a license for any of the
alleged infringed patents will be available to Brooks on reasonable terms, if at
all. A material portion of Brooks' revenues for the quarter ended December 31,
2001 and fiscal 2001 derive from the products that General Signal originally
alleged infringed its patent rights.



                                                                              32

BROOKS DOES NOT HAVE LONG-TERM CONTRACTS WITH ITS CUSTOMERS AND BROOKS'
CUSTOMERS MAY CEASE PURCHASING BROOKS' PRODUCTS AT ANY TIME.

   Brooks generally does not have long-term contracts with its customers.  As a
result, Brooks' agreements with its customers do not provide any assurance of
future sales.  Accordingly:

   -  Brooks' customers can cease purchasing its products at any time without
      penalty;

   -  Brooks' customers are free to purchase products from Brooks' competitors;

   -  Brooks is exposed to competitive price pressure on each order; and

   -  Brooks' customers are not required to make minimum purchases.

BROOKS' SOFTWARE PRODUCTS MAY CONTAIN ERRORS OR DEFECTS THAT COULD RESULT IN
LOST REVENUE, DELAYED OR LIMITED MARKET ACCEPTANCE OR PRODUCT LIABILITY CLAIMS
WITH SUBSTANTIAL LITIGATION COSTS.

   Complex software products like Brooks' can contain errors or defects,
particularly when Brooks first introduces new products or when it releases new
versions or enhancements. Any defects or errors could result in lost revenue or
a delay in market acceptance, which would seriously harm Brooks' business and
operating results. Brooks has occasionally discovered software errors in its new
software products and new releases after their introduction, and Brooks expects
that this will continue. Despite internal testing and testing by current and
potential customers, Brooks' current and future products may contain serious
defects.

   Because many of Brooks' customers use their products for business-critical
applications, any errors, defects or other performance problems could result in
financial or other damage to Brooks' customers and could significantly impair
their operations. Brooks' customers could seek to recover damages from Brooks
for losses related to any these issues. A product liability claim brought
against Brooks, even if not successful, would likely be time-consuming and
costly to defend and could adversely affect Brooks' marketing efforts.

BROOKS' FUTURE OPERATIONS COULD BE HARMED IF THE COMMERCIAL ADOPTION OF 300MM
WAFER TECHNOLOGY CONTINUES TO PROGRESS SLOWLY OR IS HALTED.

   Brooks' future operations depend in part on the adoption of new systems and
technologies to automate the processing of 300mm wafers. However, the industry
transition from the current, widely used 200mm manufacturing technology to 300mm
manufacturing technology is occurring more slowly than expected. A significant
delay in the adoption of 300mm manufacturing technology, or the failure of the
industry to adopt 300mm manufacturing technology, could significantly impair
Brooks' operations. Moreover, continued delay in transition to 300mm technology
could permit Brooks' competitors to introduce competing or superior 300mm
products at more competitive prices. As a result of these factors, competition
for 300mm orders could become vigorous and could harm Brooks' results of
operations.


                                                                              33

BROOKS' RECENT RAPID GROWTH IS STRAINING ITS OPERATIONS AND REQUIRING IT TO
INCUR COSTS TO UPGRADE ITS INFRASTRUCTURE.

   During fiscal 2000 and 2001, Brooks experienced extremely rapid growth in its
operations, its product offerings and the geographic area of its operations. The
proposed merger with PRI will continue this trend. Brooks' growth has placed a
significant strain on its management, operations and financial systems. Brooks'
future operating results will depend in part on its ability to continue to
implement and improve its operating and financial controls and management
information systems. If Brooks fails to manage its growth effectively, its
financial condition, results of operations and business could be harmed.

BROOKS' SYSTEMS INTEGRATION SERVICES BUSINESS HAS GROWN SIGNIFICANTLY RECENTLY
AND POOR EXECUTION OF THOSE SERVICES COULD ADVERSELY IMPACT BROOKS' OPERATING
RESULTS.

   The number of projects Brooks is pursuing for its systems integration
services business has grown significantly recently. This business consists of
integrating combinations of Brooks software and hardware products to provide
more comprehensive solutions for Brooks' end-user customers. The delivery of
these services typically is complex, requiring that Brooks coordinate personnel
with varying technical backgrounds in performing substantial amounts of services
in accordance with timetables. Brooks is in the early stages of developing this
business and it is subject to the risks attendant to entering a business in
which it has limited direct experience. In addition, Brooks' ability to supply
these services and increase its revenues is limited by its ability to retain,
hire and train systems integration personnel. Brooks believes that there is
significant competition for personnel with the advanced skills and technical
knowledge that it needs. Some of Brooks' competitors may have greater resources
to hire personnel with those skills and knowledge. Brooks' operating margins
could be adversely impacted if it does not effectively hire and train additional
personnel or deliver systems integration services to its customers on a
satisfactory and timely basis consistent with its budgets.

THE EFFECT OF TERRORIST THREATS ON THE GENERAL ECONOMY COULD DECREASE BROOKS'
REVENUES.

   On September 11, 2001, the United States was subject to terrorist attacks at
the World Trade Center buildings in New York City and the Pentagon in
Washington, D.C. The potential near- and long-term impact these attacks may have
in regards to Brooks' suppliers and customers, markets for their products and
the U.S. economy are uncertain. There may be other potential adverse effects on
Brooks' operating results due to this significant event that Brooks cannot
foresee.

BROOKS' BUSINESS MAY BE HARMED BY INFRINGEMENT CLAIMS OF ASYST TECHNOLOGIES,
INC.

   Brooks acquired certain assets, including a transport system known as
IridNet, from the Infab division of Jenoptik AG on September 30, 1999. Asyst
Technologies, Inc. had previously filed suit against Jenoptik AG and other
parties (collectively, the "defendants"), claiming that products of the
defendants, including IridNet, infringe Asyst's patents. This ongoing litigation
may ultimately affect certain products sold by Brooks. Brooks has received
notice that Asyst may amend its complaint to name Brooks as an additional
defendant. Based on


                                                                              34

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS - Continued


Brooks' investigation of Asyst's allegations, Brooks does not believe it is
infringing any claims of Asyst's patents. Brooks intends to continue to support
Jenoptik to argue vigorously, among other things, the position that the IridNet
system does not infringe the Asyst patents. If Asyst prevails in prosecuting its
case, Asyst may seek to prohibit Brooks from developing, marketing and using the
Iridnet product without a license. Because patent litigation can be extremely
expensive, time-consuming, and its outcome uncertain, Brooks may seek to obtain
licenses to the disputed patents. Brooks cannot guarantee that licenses will be
available to it on reasonable terms, if at all. If a license from Asyst is not
available, Brooks could be forced to incur substantial costs to reengineer the
IridNet product, which could diminish its value. In any case, Brooks may face
litigation with Asyst. Such litigation could be costly and would divert Brooks
management's attention and resources. In addition, even though sales of IridNet
comprised less than 1% of total revenues for fiscal 2001, if Brooks does not
prevail in such litigation, Brooks could be forced to pay damages or amounts in
settlement. Jenoptik has indemnified Brooks for losses Brooks may incur in this
action.


                  RISK FACTORS RELATING TO BROOKS' ACQUISITIONS

BROOKS HAS ANNOUNCED A MERGER WITH PRI, AND UNCERTAINTY REGARDING THE MERGER MAY
DISRUPT BROOKS' OPERATIONS AND ADVERSELY AFFECT ITS BUSINESS.

   On October 24, 2001, Brooks announced its proposed merger with PRI
Automation, Inc. Brooks cannot guarantee that the merger will occur. The merger
will happen only if stated conditions are met, including approval of the
issuance of shares in the merger by Brooks' stockholders, approval of the merger
by PRI's stockholders, clearance of the merger under United States and foreign
antitrust laws, and the absence of any material adverse change in the business
of Brooks or PRI. Many of the conditions are outside the control of Brooks and
PRI, and both parties also have stated rights to terminate the merger agreement.
Accordingly, there may be uncertainty regarding the completion of the merger.
This uncertainty may cause customers, suppliers and channel partners to delay or
defer decisions concerning Brooks, which could negatively affect its business.
Customers, suppliers and channel partners may also seek to change existing
agreements with Brooks as a result of the merger. Any delay or deferral of those
decisions or changes in existing agreements could have a material adverse effect
on Brooks' business, regardless of whether the merger is ultimately completed.
Many costs related to the merger, such as legal, accounting, financial advisor
and financial printing fees, must be paid by Brooks regardless of whether the
merger is completed. If the merger is not completed for any reason, Brooks may
be subject to a number of risks, including a decline in the market price of
Brooks common stock, to the extent that the relevant current market price
reflects a market assumption that the merger will be completed, and substantial
disruption to Brooks' business and distraction of its workforce and management
team. In addition, employees who are uncertain about their future with the
combined company or who do not wish to work for the combined company may seek
employment elsewhere, which could impair Brooks' ability to operate its
business.


                                                                              35

BROOKS' BUSINESS COULD BE HARMED IF BROOKS FAILS TO ADEQUATELY INTEGRATE THE
OPERATIONS OF THE BUSINESSES IT HAS ACQUIRED.

   Brooks has completed a number of acquisitions in a short period of time.
Brooks' management must devote substantial time and resources to the integration
of the operations of its acquired businesses with its core businesses and with
each other. If Brooks fails to accomplish this integration efficiently, Brooks
may not realize the anticipated benefits of its acquisitions. The process of
integrating supply and distribution channels, research and development
initiatives, computer and accounting systems and other aspects of the operation
of its acquired businesses, presents a significant challenge to Brooks'
management. This is compounded by the challenge of simultaneously managing a
larger entity. These businesses have operations and personnel located in Asia,
Europe and the United States and present a number of additional difficulties of
integration, including:

   -  assimilating products and designs into integrated solutions;

   -  informing customers, suppliers and distributors of the effects of the
      acquisitions and integrating them into Brooks' overall operations;

   -  integrating personnel with disparate business backgrounds and cultures;

   -  defining and executing a comprehensive product strategy;

   -  managing geographically remote units;

   -  managing the risks of entering markets or types of businesses in which
      Brooks has limited or no direct experience; and

   -  minimizing the loss of key employees of the acquired businesses.

   If Brooks delays the integration or fails to integrate an acquired business
or experiences other unforeseen difficulties, the integration process may
require a disproportionate amount of Brooks management's attention and financial
and other resources. Brooks' failure to adequately address these difficulties
could harm its business and financial results.

BROOKS' BUSINESS MAY BE HARMED BY ACQUISITIONS BROOKS COMPLETES IN THE FUTURE.

   Brooks plans to continue to pursue additional acquisitions of related
businesses. Brooks' identification of suitable acquisition candidates involves
risks inherent in assessing the values, strengths, weaknesses, risks and
profitability of acquisition candidates, including the effects of the possible
acquisition on Brooks' business, diversion of Brooks management's attention and
risks associated with unanticipated problems or latent liabilities. If Brooks is
successful in pursuing future acquisitions, Brooks may be required to expend
significant funds, incur additional debt or issue additional securities, which
may negatively affect Brooks' results of operations and be dilutive to its
stockholders. If Brooks spends significant funds or incurs additional debt,
Brooks' ability to obtain financing for working capital or other purposes could
decline, and Brooks may be more vulnerable to economic downturns and competitive
pressures. Brooks cannot guarantee that it will be able to finance additional
acquisitions or that it will realize any anticipated benefits from acquisitions
that Brooks completes. Should Brooks successfully acquire another business, the
process of integrating acquired operations into Brooks' existing operations may
result in unforeseen operating difficulties and may require significant
financial resources that would otherwise be available for the ongoing
development or expansion of Brooks' existing businesses.

                  RISK FACTORS RELATING TO BROOKS' COMMON STOCK

BROOKS' OPERATING RESULTS FLUCTUATE SIGNIFICANTLY, WHICH COULD NEGATIVELY IMPACT
ITS BUSINESS AND ITS STOCK PRICE.

   Brooks' revenues, margins and other operating results can fluctuate
significantly from quarter to quarter depending upon a variety of factors,
including:

   -  the level of demand for semiconductors in general;

   -  cycles in the market for semiconductor manufacturing equipment and
      automation software;

   -  the timing, rescheduling, cancellation and size of orders from Brooks'
      customer base;

   -  Brooks' ability to manufacture, test and deliver products in a timely and
      cost-effective manner;

   -  Brooks' success in winning competitions for orders;

   -  the timing of Brooks' new product announcements and releases and those of
      its competitors;

   -  the mix of products it sells;

   -  the timing of any acquisitions and related costs;

   -  competitive pricing pressures; and

   -  the level of automation required in fab extensions, upgrades and new
      facilities.

   Brooks entered the factory automation software business in fiscal 1999.
Brooks believes a substantial portion of its revenues from this business will
depend on achieving project milestones. As a result, Brooks' revenue from this
business will be subject to fluctuations depending upon a number of factors,
including whether Brooks can achieve project milestones on a timely basis, if at
all, as well as the timing and size of projects.

BROOKS' STOCK PRICE IS VOLATILE.

   The market price of Brooks' common stock has fluctuated widely. For example,
between April 4, 2001 and April 30, 2001, the closing price of Brooks' common
stock rose from approximately $35.45 to $62.61 per share and between August 28,
2001 and September 28, 2001, the price of Brooks' common stock dropped from
approximately $48.15 to $26.59 per share. Consequently, the current market price
of Brooks' common stock may not be indicative of future market prices, and
Brooks may be unable to sustain or increase the value of an investment in its
common stock. Factors affecting Brooks' stock price may include:

   -  variations in operating results from quarter to quarter;

   -  changes in earnings estimates by analysts or Brooks' failure to meet
      analysts' expectations;

   -  changes in the market price per share of Brooks' public company customers;

   -  market conditions in the industry;

   -  general economic conditions;

   -  low trading volume of Brooks common stock; and

   -  the number of firms making a market in Brooks common stock.

   In addition, the stock market has recently experienced extreme price and
volume fluctuations. These fluctuations have particularly affected the market
prices of the securities of high technology companies like Brooks. These market
fluctuations could adversely affect the market price of Brooks' common stock.

BECAUSE A LIMITED NUMBER OF STOCKHOLDERS, INCLUDING A MEMBER OF BROOKS'
MANAGEMENT TEAM, OWNS A SUBSTANTIAL NUMBER OF SHARES OF BROOKS COMMON STOCK AND
ARE PARTIES TO VOTING AGREEMENTS, THEIR DECISIONS MAY BE DETRIMENTAL TO YOUR
INTERESTS.

   By virtue of their stock ownership and voting agreements, Robert J. Therrien,
Brooks' president and chief executive officer, and Jenoptik AG have the power to
significantly influence Brooks' affairs and are able to influence the outcome of
matters required to be submitted to stockholders for approval, including the
election of Brooks' directors, amendments to Brooks' certificate of
incorporation, mergers, sales of assets and other acquisitions or sales. These
stockholders may exercise their influence over Brooks in a manner detrimental to
your interests. As of December 7, 2001, Mr. Therrien and M+W Zander Holding
GmbH, a subsidiary of Jenoptik AG, beneficially owned approximately 9.7% of
Brooks' common stock.

   Brooks has a stockholders agreement with Mr. Therrien, M+W Zander Holding
GmbH and Jenoptik AG under which M+W Zander Holding GmbH agreed to vote all of
its shares on all matters in accordance with the recommendation of a majority of
Brooks' board of directors.

PROVISIONS OF BROOKS' CERTIFICATE OF INCORPORATION, BYLAWS, CONTRACTS AND 4.75%
CONVERTIBLE SUBORDINATED NOTES DUE 2008 MAY DISCOURAGE TAKEOVER OFFERS AND MAY
LIMIT THE PRICE INVESTORS WOULD BE WILLING TO PAY FOR BROOKS' COMMON STOCK.

   Brooks' certificate of incorporation and bylaws contain provisions that may
make an acquisition of Brooks more difficult and discourage changes in Brooks'
management. These provisions could limit the price that investors might be
willing to pay for shares of Brooks' common stock. In addition, Brooks has
adopted a shareholder rights plan. In many potential takeover situations, rights
issued under the plan become exercisable to purchase Brooks common stock at a
price substantially discounted from the then applicable market price of Brooks
common stock. Because of its possible dilutive effect to a potential acquirer,
the rights plan would generally discourage third parties from proposing a merger
with or initiating a tender offer for us that is not approved by Brooks' board
of directors. Accordingly, the rights plan could have an adverse impact on
Brooks' stockholders who might want to vote in favor of a merger or participate
in a tender offer. In addition, Brooks may issue shares of preferred stock upon
terms the board of directors deems appropriate without stockholder approval.
Brooks' ability to issue preferred stock in such a manner could enable its board
of directors to prevent changes in its management or control. Finally, upon a
change of control of Brooks, Brooks may be required to repurchase convertible
subordinated notes at a price equal to 100% of the principal outstanding amount
thereof, plus accrued and unpaid interest, if any, to the date of the
repurchase. Such a repurchase of the notes would represent a substantial
expense; accordingly, the repayment of the notes upon a change of control of
Brooks could discourage third parties from proposing a merger with, initiating a
tender offer for or otherwise attempting to gain control of Brooks.


                                                                              38

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

INTEREST RATE EXPOSURE

Based on Brooks' overall interest exposure at December 31, 2001, including all
interest rate-sensitive instruments, a near-term change in interest rates within
a 95% confidence level based on historical interest rate movements would not
materially affect the consolidated results of operations or financial position.


CURRENCY RATE EXPOSURE

Brooks' foreign revenues are generally denominated in United States dollars.
Accordingly, foreign currency fluctuations have not had a significant impact on
the comparison of the results of operations for the periods presented. The costs
and expenses of Brooks' international subsidiaries are generally denominated in
currencies other than the United States dollar. However, since the functional
currency of Brooks' international subsidiaries is the local currency, foreign
currency translation adjustments do not impact operating results, but instead
are reflected as a component of stockholders' equity under the caption
"Accumulated other comprehensive income (loss)". To the extent Brooks expands
its international operations or changes its pricing practices to denominate
prices in foreign currencies, Brooks will be exposed to increased risk of
currency fluctuation.
