     This summary provides an overview of selected information and may not
contain all of the information that is important to you. You should read the
entire prospectus carefully, including the financial data, related notes and the
information we have incorporated by reference before making an investment
decision. Unless otherwise indicated, all information in this prospectus assumes

                               BROOKS AUTOMATION

     We are a leading supplier of integrated tool and factory automation
solutions for the global semiconductor manufacturing and related industries. Our
automation solutions are designed to optimize equipment and factory
productivity. These solutions include tool automation modules, complete
semiconductor wafer handling systems and automation software and integration
services. We sell our tool automation products principally to manufacturers of
process equipment used in semiconductor fabrication facilities, or fabs,
including Lam Research, Novellus Systems and ULVAC. We sell our factory
automation products principally to semiconductor manufacturers including Philips
Electronics, STMicroelectronics and Samsung Electronics. We also sell our
products to data storage and flat panel display manufacturers. Based upon data
published by Dataquest, an independent research group, we believe that we are
the largest independent producer of vacuum tool automation systems and a leading
independent producer of tool software and controls.

     Semiconductor manufacturers are currently making, and are expected to
continue to make, significant investments in manufacturing capacity by
constructing new semiconductor manufacturing facilities, expanding existing
facilities and upgrading existing equipment. According to Dataquest,
semiconductor manufacturers will spend about $25.1 billion on fab equipment in
2000, and this spending will grow to $38.3 billion by 2002, representing a
compound annual growth rate of 24%. Semiconductor manufacturers face challenges
in achieving and maintaining high production yields, improving use of expensive
facilities and equipment, and managing the logistics of increasingly complex
fabrication processes. Manufacturers seek to meet these challenges by using tool
and fab automation systems to:

     - maximize the flow of products through the manufacturing process;

     - minimize misprocessing and contamination; and

     - monitor and control manufacturing processes and equipment.

As a result, we expect automation to represent a growing portion of
semiconductor capital equipment spending. Dataquest estimates that in 2000
semiconductor and process equipment manufacturers will spend $1.4 billion on
manufacturing automation and control systems and that this number will grow to
$2.4 billion by 2002, representing a compound annual growth rate of 30%.

PRODUCTS

     Since September 1998, we have completed seven acquisitions that have
increased the breadth and depth of our tool and factory automation product
offerings. Today, the combination of our tool automation solutions with our
factory automation solutions and implementation services provides enabling
technology for improving factory performance. We have 59 U.S. patents and 50
pending U.S. patents including those covering vacuum robot, cluster tool
automation platform, tool interface and material tracking designs. We also have
numerous patents issued or pending in Europe, Japan, China, Taiwan, Korea and
Singapore. In fiscal 1999, we sold our tool and factory automation solutions to
more than 200 customers for use in fabs in North America, Asia and Europe.

     Tool Automation.  We offer a broad complement of tool automation systems
and service support. Our vacuum and atmospheric tool automation systems include
robots, cluster tool platforms, equipment front end modules, tool-factory
interfaces and mini-environments for isolating processing equipment and

STRATEGY

     Our goal is to maintain and expand upon our position as a leading
independent supplier of integrated tool and factory automation solutions for the
semiconductor, data storage and flat panel display manufacturing industries. The
principal elements of our strategy are as follows:

     Capitalize on the Trend Towards Increased Fab Automation. The robotic
systems integration and tool software expertise that we have developed for our
tool automation systems, coupled with our factory automation software solutions
and factory interface hardware, position us to capitalize on the current trend
towards increased fab automation. We believe several factors are contributing to
this trend, including:

     - a greater need to reduce idleness, minimize unscheduled downtime and
       increase the efficiency of tools as factory capital costs rise;

     - advanced semiconductor materials, such as copper, require new tool sets,
       greater process control and improved containment isolation;

     - increases in semiconductor wafer sizes to 300mm diameters make human
       handling impractical because of the greater weight and value of these
       wafers;

     - greater complexity of semiconductor manufacturing requires improved fab
       scheduling and process control; and

     - advances in semiconductor miniaturization require cleaner, particle-free
       production environments.

     Capitalize on the Trend Towards Increased Outsourcing.  We believe that
process tool manufacturers will outsource more of their automation content as
they focus on their core competencies to meet the demands of more sophisticated
processes. We believe semiconductor manufacturers will also outsource their
internal manufacturing software development and integration efforts as more
comprehensive and integrated solutions become available. We plan to capitalize
on these trends by offering a broader range of integrated solutions.

     Offer Integrated Tool and Factory Automation Solutions. As fabs become more
expensive, we believe our customers will demand more fully integrated solutions.
We believe fab efficiency is currently impaired by the difficulty of integrating
various point solutions. We believe we can provide more complete and integrated
solutions that address this customer need.

     Pursue Strategic Technology Alliances and Acquisitions. We intend to
continue pursuing strategic alliances and acquisitions that complement our
family of products and enable us to deliver a fully integrated, automation
solution.

                                  RISK FACTORS

     This offering involves a high degree of risk. You should carefully consider
the risks described below and the other information in this prospectus before
deciding to invest in shares of our common stock. While these are the risks and
uncertainties we believe are most important for you to consider, you should know
that they are not the only risks or uncertainties facing us or which may
adversely affect our business. 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.

                        RISKS RELATING TO OUR OPERATIONS

     The Cyclical Demand of Semiconductor Manufacturers Affects our Operating
Results.  Our 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. Demand for semiconductors is cyclical and has historically
experienced periodic downturns. During these downturns, our revenues have
dropped and we have incurred losses. We believe that downturns in the
semiconductor manufacturing industry will occur in the future and will result in
decreased demand for our products. Despite the addition of our factory
automation business in fiscal 1999, our financial results will continue to be
dependent on capital expenditures by semiconductor manufacturers. Downturns in
the semiconductor business, when fewer new facilities are being built, could
harm our financial results as have downturns in the past.

     Our Sales Volume Depends on the Sales Volume of our Original Equipment
Manufacturer Customers. We sell a majority of our tool automation products to
original equipment manufacturers who incorporate our products into their
equipment. Therefore, our revenues are directly dependent on the ability of
these customers to develop and market their equipment in a timely,
cost-effective manner.

     We Rely on a Small Number of Customers for a Large Portion of our
Revenues.  We receive a significant portion of our revenues in each fiscal
period from a limited number of customers. The loss of one or more of these
major customers, or a decrease in orders by one or more customers, would
adversely affect our business. Sales to our ten largest customers accounted for
56% of total revenues in the three months ended December 31, 1999 and 63% of
total revenues in fiscal 1999. Sales to Lam Research Corporation, our largest
customer, accounted for approximately 14% of total revenues in the three months
ended December 31, 1999 and 15% of our total revenues in fiscal 1999.

     Delays in Shipment of a Few of our Large Orders Could Substantially
Decrease our Revenues. Historically, a substantial portion of our quarterly and
annual revenues came from sales of a small number of large orders. These orders
consist of products with high selling prices compared to our other products. As
a result, the timing of the recognition of revenue from one of these large
orders can have a significant impact on our total revenues and operating results
for a particular period. Our operating results could be harmed if even 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.

     We Have Significant Fixed Costs which Are Not Easily Reduced if Revenues
Fall Below Expectations. Our expense levels are based in part on our future
revenue expectations. Many of our expenses, particularly those relating to
capital equipment and manufacturing overhead, are relatively fixed. If we do not
meet our sales goals we may be unable to rapidly reduce these fixed costs. Our
ability to reduce expenses is further constrained because we must continue to
invest in research and development to maintain our competitive position and to
maintain service and support for our existing global customer base. Accordingly,
if we suffer an unexpected downturn in revenue, our inability to reduce fixed
costs rapidly could increase the adverse impact on our results of operations.

     Our Lengthy Sales Cycle Requires us to Incur Significant Expenses with No
Assurance that we Will Generate Revenue.  Our tool automation products are
generally incorporated into original equipment manufacturer equipment at the
design stage. To obtain new business from our original equipment

                                        8
<PAGE>   11

manufacturer customers, we must develop products for selection by a potential
customer at the design stage. This often requires us 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. We also must complete successfully a lengthy evaluation
period before we can achieve volume sales of our manufacturing execution system
software and process optimization software to our factory automation customers.
We cannot guarantee that we will continue to achieve design wins or satisfy
evaluations by our factory automation customers of our software. We cannot
guarantee that the equipment manufactured by our original equipment
manufacturing customers will be commercially successful. If we or our original
equipment manufacturing customers fail to develop and introduce new products
successfully and in a timely manner, our business and financial results will
suffer.

     Our International Business Operations Expose us to a Number of Difficulties
in Coordinating our Activities Abroad and in Dealing with Multiple Regulatory
Environments.  Approximately 52% of our total revenues in the three months ended
December 31, 1999 and 41% of our total revenues in fiscal 1999 were derived from
customers located outside North America. We anticipate that international sales
will continue to account for a significant portion of our revenues. Our vendors
are located in several different foreign countries. As a result of our
international business operations, we are subject to various risks, including:

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

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

     - possible adverse tax consequences;

     - governmental currency controls;

     - changes in various regulatory requirements;

     - political and economic changes and disruptions; and

     - export/import controls and tariff regulations.

     To support our international customers, we maintain locations in several
countries, including Japan, South Korea, Germany, United Kingdom, Malaysia,
Taiwan, Singapore and Canada. We cannot guarantee that we will be able to manage
these operations effectively. We cannot assure you that our investment in these
international operations will enable us to compete successfully in international
markets or to meet the service and support needs of our customers, some of whom
are located in countries where we have no infrastructure.

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

     We Must Continually Improve our Technology to Remain Competitive.
Technology changes rapidly in the semiconductor, data storage and flat panel
display manufacturing industries. We believe our success will depend upon our
ability to enhance our existing products and to develop and market new products
to meet customer needs. We cannot guarantee that we will identify and adjust to
changing market conditions or succeed in introducing commercially rewarding
products or product enhancements. The success of our product development and
introduction depends on a number of factors, including:

     - accurately identifying and defining new products;

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

     - market acceptance of our products and our customers' products; and

     - determining a comprehensive, integrated product strategy.

                                        9
<PAGE>   12

     We Face Significant Competition which Could Result in Decreased Demand for
our Products or Services.  The markets for our products are intensely
competitive and we may not be able to compete successfully. We believe that our
primary competition in the tool automation market is from integrated original
equipment manufacturers that satisfy their semiconductor and flat panel display
handling needs themselves rather than by purchasing systems or modules from an
independent supplier like us. Many of these original equipment manufacturers
have substantially greater resources than we do. Applied Materials, Inc., the
leading process equipment original equipment manufacturer, develops and
manufactures its own central wafer handling systems and modules. We may not be
successful in selling our products to original equipment manufacturers that
currently satisfy their wafer or substrate handling needs themselves, regardless
of the performance or the price of our products. Moreover, integrated original
equipment manufacturers may begin to commercialize their handling capabilities
and become our competitors.

     We believe that the primary competitive factors in the end-user
semiconductor manufacturer market for factory automation software and process
control software are product functionality, price/performance, ease of use,
hardware and software platform compatibility, vendor reputation and financial
stability. The relative importance of these competitive factors may change over
time. We directly compete in this market with various competitors, including
Applied Materials-Consilium, PRI-Promis, IBM-Poseidon and numerous small,
independent software companies. We also compete with the in-house software
staffs of semiconductor manufacturers like NEC. Most of those manufacturers have
substantially greater resources than us.

     We believe 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, we compete directly with Asyst, Fortrend, Kensington and Rorze.
Some of these competitors have substantial financial resources and extensive
engineering, manufacturing and marketing capabilities.

     We believe our sale of products for the flat panel display process
equipment market is heavily dependent upon our penetration of the Japanese
market. In addressing the Japanese markets, we may be at a competitive
disadvantage to Japanese suppliers that, historically, have been the supplier of
choice to these markets.

     Much of our Success and Value Lies in our Ownership and Use of Intellectual
Property and our Failure to Protect that Property Could Adversely Affect our
Future Growth.  Our ability to compete is heavily affected by our ability to
protect our intellectual property. We rely primarily on trade secret laws,
confidentiality procedures, patents, copyrights, trademarks and licensing
arrangements to protect our intellectual property. The steps we have taken to
protect our technology may be inadequate. Existing trade secret, trademark and
copyright laws offer only limited protection. Our patents could be invalidated
or circumvented. The laws of certain foreign countries in which our products are
or may be developed, manufactured or sold may not fully protect our products or
intellectual property rights. This may make the possibility of piracy of our
technology and products more likely. We cannot guarantee that the steps we have
taken to protect our intellectual property will be adequate to prevent
misappropriation of our technology. There has been substantial litigation
regarding patent and other intellectual property rights in semiconductor-related
industries. We may engage in litigation to:

     - enforce our patents;

     - protect our trade secrets or know-how;

     - defend ourselves against claims we infringe 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 us and divert the
attention of our management, which could harm our operating results.

                                       10
<PAGE>   13

     Our Operations Could Infringe on the Intellectual Property Rights of
Others.  Particular aspects of our 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 our business. We cannot predict the extent to which we
may be required to seek licenses or alter our products so that they no longer
infringe the rights of others. We cannot guarantee that the terms of any
licenses we may be required to seek will be reasonable. Similarly, changing our
products or processes to avoid infringing the rights of others may be costly or
impractical or could detract from the value of our products.

     Our Business May be Harmed by Infringement Claims of General Signal or
Applied Materials.  We received notice from General Signal Corporation alleging
infringements of its patent rights by certain of our products. The notification
advised us 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 us, these
five patents would appear to be the patents referred to by General Signal in its
prior notice to us. Applied Materials has not contacted us regarding these
patents.

     We do not Have Long-Term Contracts with our Customers and our Customers May
Cease Purchasing our Products at Any Time.  We generally do not have long-term
contracts with our customers. As a result, our agreements with our customers do
not provide any assurance of future sales. Accordingly:

     - our customers can cease purchasing our products at any time without
       penalty;

     - our customers are free to purchase products from our competitors;

     - we are exposed to competitive price pressure on each order; and

     - our customers are not required to make minimum purchases.

     Year 2000 Readiness; Year 2000 Problems Could Disrupt our Business.  The
year 2000 problem is the potential for system and processing failure of
date-related data as the result of computer-controlled systems using two digits
rather than four digits to define the applicable year. This could result in
system failure or miscalculations causing disruptions of operations, including,
among other things, temporary inability to process transactions, send invoices,
or engage in similar normal business activities. Problems associated with the
year 2000 may not become apparent until some time after January 2000.

     We have evaluated our internal software and products for year 2000
problems. We believe that our products and business will not be substantially
affected by the year 2000 problem and that we have no significant exposure to
liabilities related to the year 2000 problem for the products that we have sold.
We have also communicated with others, including suppliers and customers whose
computer systems' functionality could directly impact our operations.

     Although we believe our planning efforts are adequate to address our year
2000 concerns, undetected year 2000 problems may cause us to experience negative
consequences or significant costs. We cannot be sure that our suppliers,
customers or businesses that we may acquire will not experience similar
consequences or costs. Such consequences or costs could adversely affect our
business.

                          RISKS RELATING TO OUR GROWTH

     Rapid Growth is Straining our Operations and Requiring us to Incur Costs to
Upgrade our Infrastructure.  During the last two quarters, we have experienced
extremely rapid growth in our operations, the number of our employees, our
product offerings and the geographic area of our operations. Our growth places a
significant strain on our management, operations and financial systems. Our
future operating results will be dependent in part on our ability to continue to
implement and improve our operating and financial controls and management
information systems. If we fail to manage our growth effectively, our financial
condition, results of operations and business could be materially adversely
affected.

                                       11
<PAGE>   14

     Our Operating Results Would be Harmed if One of our Key Suppliers Fails to
Deliver Components for our Products.  We currently procure many of our
components on an as needed, purchase order basis. We do not carry significant
inventories or have any long-term supply contracts with our vendors. With the
recent increased demand for semiconductor manufacturing equipment, our suppliers
are facing significant challenges in providing components on a timely basis. Our
inability to obtain components in required quantities or of acceptable quality
could result in significant delays or reductions in product shipments. This
would materially and adversely affect our operating results.

     Our Business Could be Harmed if we Fail to Adequately Integrate the
Operations of our Acquisitions. Our management must devote substantial time and
resources to the integration of the operations of our acquired businesses with
our business and with each other. If we fail to accomplish this integration
efficiently, we may not realize the anticipated benefits of our acquisitions.
The process of integrating supply and distribution channels, research and
development initiatives, computer and accounting systems and other aspects of
the operation of our acquired businesses, presents a significant challenge to
our management. This is compounded by the challenge of simultaneously managing a
larger entity. We have completed a number of acquisitions in a short period of
time. These businesses have operations and personnel located in Asia, Europe and
the United States and present a number of additional difficulties of
integration, including:

     - difficulties in the assimilation of products and designs into integrated
       solutions;

     - difficulties in informing customers, suppliers and distributors of the
       effects of the acquisitions and integrating them into our overall
       operations;

     - difficulties integrating personnel with disparate business backgrounds
       and cultures;

     - difficulties in defining and executing a comprehensive product strategy;

     - difficulties in managing geographically remote units;

     - difficulties associated with managing the risks of entering markets or
       types of businesses in which we have limited or no direct experience; and

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

     If we delay integrating or fail to integrate an acquired business or
experience other unforeseen difficulties, the integration process may require a
disproportionate amount of our management's attention and financial and other
resources. Our failure to adequately address these difficulties could harm our
business and financial results.

     Our Business May be Harmed by Acquisitions we Complete in the Future.  We
plan to continue to pursue additional acquisitions of related businesses. Our
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 our
business, diversion of our management's attention and risks associated with
unanticipated problems or latent liabilities. If we are successful in pursuing
future acquisitions, we will be required to expend significant funds, incur
additional debt or issue additional securities, which may negatively affect our
results of operations and be dilutive to our stockholders. If we spend
significant funds or incur additional debt, our ability to obtain financing for
working capital or other purposes could decline and we may be more vulnerable to
economic downturns and competitive pressures. We cannot guarantee that we will
be able to finance additional acquisitions or that we will realize any
anticipated benefits from acquisitions that we complete. Should we successfully
acquire another business, the process of integrating acquired operations into
our 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 our existing business.

                                       12

     We May not be Able to Recruit and Retain Necessary Personnel Because of
Intense Competition for Highly Skilled Personnel.  We need to hire and retain
substantial numbers of employees with technical backgrounds for both our
hardware and software engineering and support staffs. The market for these
employees is intensively competitive, and we have occasionally experienced
delays in hiring these personnel. Due to the cyclical nature of the demand for
our products, we have had to reduce our workforce and then rebuild our workforce
as our business has gone through downturns followed by upturns. We currently
need to hire a number of highly skilled employees, especially in manufacturing,
to meet customer demand. Due to the competitive nature of the labor markets in
which we operate, this type of employment cycle increases our risk of not being
able to retain and recruit key personnel. Our inability to recruit, retain and
train adequate numbers of qualified personnel on a timely basis could adversely
affect our ability to develop, manufacture, install and support our products.

                       RISKS RELATING TO OUR COMMON STOCK

     Our Operating Results Fluctuate Significantly, which Could Negatively
Impact our Business and our Stock Price.  Our margins, revenues 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 and size of orders from our customer base;

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

     - our success in winning competitions for orders;

     - the timing of our new product announcements and releases and those of our
       competitors;

     - the mix of products sold by us;

     - competitive pricing pressures; and

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

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

     The Volatility of our Stock Price Could Adversely Affect an Investment in
our Stock.  The market price of our common stock has fluctuated widely. For
example, between August 25, 1999 and August 31, 1999, the price of our common
stock dropped from approximately $25.13 to $21.75 per share. Between January 4,
2000 and February 11, 2000, the price of our common stock rose from
approximately $30.63 to $67.75 per share. Consequently, the current market price
of our common stock may not be indicative of future market prices, and we may
not be able to sustain or increase the value of an investment in our common
stock. Factors affecting our stock price may include:

     - variations in operating results from quarter to quarter;

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

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

     - market conditions in the industry;

     - general economic conditions;

     - low trading volume of our common stock; and

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

                                       13
<PAGE>   16

     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 us. These market
fluctuations could adversely affect the market price of our common stock.

     Because a Limited Number of Stockholders, Including a Member of our
Management Team, Own a Substantial Number of our Shares and are Parties to
Voting Agreements, Decisions May be Made by them that are Detrimental to your
Interests.  By virtue of their stock ownership and voting agreements, Robert J.
Therrien, our president and chief executive officer, Jenoptik A.G. and Daifuku
America Corporation have the power to significantly influence our affairs and
are able to influence the outcome of matters required to be submitted to
stockholders for approval, including the election of our directors, amendments
of our certificate of incorporation, mergers, sales of assets and other
acquisitions or sales. We cannot assure you that these stockholders will not
exercise their influence over us in a manner detrimental to your interests. Upon
completion of this offering, Mr. Therrien will hold approximately 5.3% of our
common stock, M+W Zander Holding GmbH, a subsidiary of Jenoptik, will hold
approximately 5.4% of our common stock and Daifuku America Corporation, the U.S.
affiliate of Daifuku Co. Ltd. of Japan, will hold approximately 2.4% of our
common stock. Collectively, these stockholders will hold approximately 13.1% of
our outstanding common stock. On September 30, 1999 we entered into a
stockholder agreement with Mr. Therrien, M+W and Jenoptik. Under this agreement,
until M+W no longer holds all of the shares received from us when we acquired
the Infab Division from Jenoptik or until September 30, 2004, whichever occurs
first, we agree to nominate a reasonably acceptable Jenoptik designee to our
board of directors in each election of our directors. Mr. Therrien agreed to
vote all his shares in favor of Jenoptik's nominee. Jenoptik agreed to vote in
favor of the other candidates to our board of directors that are nominated by
our existing board. Jenoptik also agreed to vote for other matters in the same
proportion as the votes cast by the other holders of our common stock. On
January 6, 2000, in connection with our acquisition of Auto-Soft Corporation and
AutoSimulations, Inc. from Daifuku America Corporation, we entered into a
stockholder agreement with Daifuku America Corporation and Daifuku Co., Ltd.
Under the stockholder agreement, Daifuku agreed to vote all of its shares of our
common stock at each meeting of our stockholders in accordance with the
recommendation of our board of directors.

     Provisions of our Certificate of Incorporation, Bylaws and Contracts May
Discourage Takeover Offers and May Limit the Price Investors Would be Willing to
Pay for our Common Stock.  Our certificate of incorporation and bylaws contain
provisions that may make an acquisition of us more difficult and discourage
changes in our management. These provisions could limit the price that certain
investors might be willing to pay in the future for shares of our common stock.
In addition, we have adopted a rights plan. In many potential takeover
situations, rights issued under the plan become exercisable to purchase our
common stock at a price substantially discounted from the then applicable market
price of our common stock. Because of its possible dilutive effect to a
potential acquiror, 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 our board of directors. Accordingly, the rights plan could have an
adverse impact on our stockholders who might want to vote in favor of the merger
or participate in the tender offer. In addition, shares of our preferred stock
may be issued upon terms the board of directors deems appropriate without
stockholder approval. Our ability to issue preferred stock in such a manner
could enable our board of directors to prevent changes in our management or
control.

First Quarter (through March 7, 2000)......................  $83.25    $29.75
</TABLE>

     On March 7, 2000, the closing price reported on the Nasdaq National Market
for our common stock was $78.63 per share. On February 10, 2000 there were
approximately 294 holders of record of our common stock.

                                DIVIDEND POLICY

     Other than dividends paid by one of our subsidiaries prior to its
acquisition by us, we have never paid or declared any cash dividends on our
capital stock and do not plan to pay any cash dividends in the foreseeable
future. Our current policy is to retain all of our earnings to finance future
growth. Our lending arrangement prohibits the payment of dividends without the
prior approval of our lender.

                                USE OF PROCEEDS

     We estimate that the net proceeds to us from the sale of the 2,750,000
shares of common stock we are offering will be approximately $197.1 million. If
the underwriters fully exercise the over-allotment option, the net proceeds to
us will be approximately $220.1 million. "Net proceeds" is what we expect to
receive based on the public offering price of $76.00 per share and after we pay
the underwriting discount and other estimated expenses for this offering. We
will not receive any portion of the proceeds from the sale of shares of common
stock by the selling stockholders.

     We expect to use the net proceeds for general corporate purposes, including
working capital, leasehold improvements and capital equipment. We may also use a
portion of the net proceeds to acquire additional businesses, products and
technologies, or to establish strategic alliances that we believe will
complement our current or future business. We have entered into a letter of
intent to acquire a software business for approximately $300,000 in cash,
$300,000 in the form of shares of our common stock and an ongoing royalty
payment upon achievement of milestones. Although we are in discussions regarding
other potential strategic acquisitions, as of the date of this prospectus we do
not have any other agreements or commitments to enter into any acquisitions,
except as disclosed under the section entitled "Recent Events," and we have not
allocated a specific amount of the net proceeds for strategic acquisitions.

     We will retain broad discretion in the allocation of the net proceeds of
this offering. Pending the uses described above, we intend to invest the net
proceeds of this offering in short-term interest-bearing securities. We cannot
predict whether the proceeds will be invested to yield a favorable return.

                                 CAPITALIZATION

     The following table presents our capitalization as of December 31, 1999:

       Corporation in January 2000 for $27.0 million in cash, 535,404 shares of
       common stock and a $16.0 million promissory note due on January 5, 2001;
       and

     - on a pro forma as adjusted basis to reflect the acquisition and the sale
       of 2,750,000 shares of common stock we are offering with this prospectus
       at the offering price of $76.00 per share, and the application of the
       proceeds, net of the underwriting discount and our estimated expenses.

     - 574,334 shares of common stock reserved for issuance pursuant to our
       employee stock purchase plan (includes an increase of 500,000 shares
       approved by our stockholders on February 24, 2000); and

     - 1,186,388 shares of common stock reserved for issuance pursuant to stock
       options not yet granted under all of our stock option plans (includes an
       increase of 1,000,000 shares relating to the establishment of a new
       option plan approved by our stockholders on February 24, 2000).

                                    DILUTION

     Our net tangible book value as of December 31, 1999 was approximately
$133.4 million, or $10.44 per share. Net tangible book value per share
represents the amount of our total tangible assets less total liabilities
divided by the total number of shares of common stock outstanding. After giving
effect to: (1) the sale by us of 2,750,000 shares of common stock offered by
this prospectus at the offering price of $76.00 per share and after deducting
the underwriting discount and estimated offering expenses; and (2) our
acquisition of the businesses of Auto-Soft Corporation and AutoSimulations, Inc.
from Daifuku America Corporation in January 2000 for $27.0 million in cash,
535,404 shares of common stock and a $16.0 million promissory note due on
January 5, 2001, our pro forma net tangible book value at December 31, 1999
would have been approximately $296.5 million, or $18.46 per share. This
represents an immediate increase in net tangible book value of $8.02 per share
to existing stockholders and an immediate dilution of $57.54 per share to new
investors in this offering, as illustrated by the following table:

Pro forma net tangible book value dilution per share to new
  investors................................................            $57.54
                                                                       ======
</TABLE>

     This discussion of dilution, and the table quantifying it, assume no
exercise of any outstanding stock options. The exercise of stock options
outstanding under our stock option plans having an exercise price less than the
offering price would increase the dilutive effect to new investors.

                       PRINCIPAL AND SELLING STOCKHOLDERS

     The following table provides information known to us regarding the
beneficial ownership of our common stock as of February 4, 2000, and as adjusted
to reflect the sale of common stock offered by this prospectus, for each of the
following:

     - each selling stockholder;

     - each of our named executive officers in the Summary Compensation Table
       contained in the Proxy Statement for Annual Meeting of the Stockholders
       to be held on February 24, 2000;

     - each of our directors;

     - all named executive officers and directors as a group; and

     - each person who beneficially owns more than 5% of our common stock.

     Unless otherwise indicated, to our knowledge, each person identified
possesses sole voting and investment power with respect to the shares listed
except to the extent shared by such person's spouse under applicable law.

     We have granted the underwriters an option to purchase a maximum of 320,500
additional shares to cover over-allotments of shares. Some of the selling
stockholders have granted the underwriters an option to purchase a maximum of
167,000 additional shares to cover over-allotments of shares. If the
underwriters exercise their over-allotment option, the underwriters will
purchase the first 100,000 shares from Daifuku America Corporation. If the
underwriters purchase more than 100,000 shares under their over-allotment
option, the underwriters will purchase the additional shares pro rata from us
and some of the selling stockholders, as described in the table below. The
numbers shown in the table below assume no exercise by the underwriters of their
over-allotment option.

     In computing the number of shares beneficially owned by a person and the
percentage ownership of that person, shares of common stock which that person
could purchase by exercising outstanding stock options, warrants or other rights
prior to April 4, 2000 are deemed outstanding. These shares, however, are not
deemed outstanding for the purposes of computing the percentage ownership of any
other person.

     Credit Suisse First Boston Corporation and SG Cowen Securities Corporation
are acting as joint-lead managers in this offering. Credit Suisse First Boston
Corporation is acting as sole book-running manager.

     The underwriting agreement provides that the underwriters are obligated to
purchase all of the shares of common stock offered in this offering if any are
purchased, other than those shares covered by the over-allotment option
described below. The underwriting agreement also provides that if an underwriter
defaults the purchase commitments of nondefaulting underwriters may be increased
or the offering of common stock may be terminated.

     The underwriters have a 30-day option to purchase up to 320,500 additional
shares of common stock from us and up to 167,000 additional shares of common
stock from seven of the selling stockholders at the public offering price, less
the underwriting discounts and commissions. This option may be exercised only to
cover any over-allotments of common stock.

     The underwriters propose to offer the shares of common stock initially at
the public offering price set forth on the cover page of this prospectus and to
selling group members at that price less a concession of $2.40 per share. The
underwriters and selling group members may allow a discount of $0.10 per share
on sales to other broker/dealers. After the public offering, the public offering
price and concession and discount to broker/dealers may be changed by the
representatives.

and the selling stockholders will pay.

     We have agreed that we will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933
relating to, any shares of our common stock or securities convertible into or
exchangeable or exercisable for any shares of our common stock, or publicly
disclose the intention to make any such offer, sale, pledge, disposition or
filing, without the prior written consent of Credit Suisse First Boston
Corporation for a period of 90 days after the date of this prospectus, except
issuances pursuant to our employee stock purchase plan and pursuant to the
exercise of employee stock options outstanding on the date hereof.

     Our officers and directors have agreed that they will not offer, sell,
contract to sell, pledge or otherwise dispose of, directly or indirectly, any
shares of our common stock or securities convertible into or exchangeable or
exercisable for any shares of our common stock, enter into a transaction which
would have the same effect, or enter into any swap, hedge or other arrangement
that transfers, in whole or in part, any of the economic consequences of
ownership of our common stock, whether any such aforementioned transaction is to
be settled by delivery of our common stock or such other securities, in cash or
otherwise, or publicly disclose the intention to make any such offer, sale,
pledge or disposition, or to enter into any such transaction, swap, hedge or
other arrangement, without, in each case, the prior written consent of Credit
Suisse First Boston Corporation for a period of 90 days after the date of this
prospectus.

     We and the selling stockholders have agreed to indemnify the underwriters
against liabilities under the Securities Act, or contribute to payments which
the underwriters may be required to make in that respect.

     The shares of our common stock are listed on the Nasdaq National Market
under the symbol "BRKS."

     The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions, penalty bids and passive market making in
accordance with Regulation M under the Securities Exchange Act of 1934.

     - Over-allotment involves syndicate sales in excess of the offering size,
       which creates a syndicate short position.

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.

     - Syndicate covering transactions involve purchases of the common stock in
       the open market after the distribution has been completed in order to
       cover syndicate short positions.

     - Penalty bids permit the representatives to reclaim a selling concession
       from a syndicate member when common stock originally sold by the
       syndicate member is purchased in a stabilizing or syndicate covering
       transaction to cover syndicate short positions.

     - In passive market making, market makers in the common stock who are
       underwriters or prospective underwriters may, subject to certain
       limitations, make bids for or purchases of the common stock until the
       time, if any, at which a stabilizing bid is made.

These stabilizing transactions, syndicate covering transactions and penalty bids
may cause the price of our common stock to be higher than it would otherwise be
in the absence of such transactions. These transactions may be effected on the
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.

                          NOTICE TO CANADIAN RESIDENTS

                              RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we and the selling
stockholders prepare and file a prospectus with the


                                       24
<PAGE>   27

securities regulatory authorities in each province where trades of common stock
are effected. Accordingly, any resale of the common stock in Canada must be made
in accordance with applicable securities laws which will vary depending on the
relevant jurisdiction, and which may require resales to be made in accordance
with available statutory exemptions or pursuant to a discretionary exemption
granted by the applicable Canadian securities regulatory authority. Purchasers
are advised to seek legal advice prior to any resale of the common stock.

                         REPRESENTATIONS OF PURCHASERS

     Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us, the selling stockholders and the
dealer from whom such purchase confirmation is received that (i) such purchaser
is entitled under applicable provincial securities laws to purchase such common
stock without the benefit of a prospectus qualified under such securities laws,
(ii) where required by law, that such purchaser is purchasing as principal and
not as agent and (iii) such purchaser has reviewed the text above under "Resale
Restrictions."

                     RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

                          ENFORCEMENT OF LEGAL RIGHTS

     All of the issuer's directors and officers, as well as the experts named
herein and the selling stockholders may be located outside of Canada and, as a
result, it may not be possible for Canadian purchasers to effect service of
process within Canada upon the issuer or such persons. All or a substantial
portion of the assets of the issuer and such persons may be located outside of
Canada and, as a result, it may not be possible to satisfy a judgment against
the issuer or such persons inside Canada or to enforce a judgment obtained in
Canadian courts against such issuer or persons outside of Canada.

                      NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one such report
must be filed in respect of common stock acquired on the same date and under the
same prospectus exemption.

                    TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of

     We are a reporting company and file annual, quarterly and current reports,
proxy statements and other information with the Securities and Exchange
Commission, or the SEC. You may read and copy these reports, proxy statements
and other information at the SEC's public reference rooms at 450 Fifth Street,
NW., Washington, D.C., and in New York, NY and Chicago, IL. You can request
copies of these documents by writing to the SEC and paying a fee for the copying
cost. Please call the SEC at 1-800-SEC-0330 for more information about the
operation of the public reference rooms. Our SEC filings are also available at
the SEC's web site at http://www.sec.gov. In addition, you can read and copy our

     We have filed with the SEC a registration statement on Form S-3 under the
Securities Act of 1933 with respect to the common stock offered in connection
with this prospectus. This prospectus does not contain all of the information
set forth in the registration statement. We have omitted certain parts of the
registration statement in accordance with the rules and regulations of the SEC.
For further information with respect to us and the common stock, you should
refer to the registration statement. Statements contained in this prospectus as
to the contents of any contract or other document are not necessarily complete
and, in each instance, you should refer to the copy of such contract or document
filed as an exhibit to or incorporated by reference in the registration
statement. Each statement as to the contents of such contract or document is
qualified in all respects by such reference. You may obtain copies of the
registration statement from the SEC's principal office in Washington, D.C. upon
payment of the fees prescribed by the SEC, or you may examine the registration
statement without charge at the offices of the SEC described above.

     The SEC allows us to "incorporate by reference" information that we file
with them, which means that we can disclose important information to you by
referring you to those documents. The information incorporated by reference is
an important part of this prospectus, and information that we file later with
the SEC will automatically update and supersede this information. We incorporate
by reference the documents listed below and any future filings we will make with
