                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors" and the Company's consolidated financial
statements appearing elsewhere or incorporated by reference in this Prospectus.
Unless the context otherwise requires, the "Company" and "SpeedFam" refer only
to SpeedFam International, Inc. and its wholly owned subsidiaries.
 
                                  THE COMPANY
 
     SpeedFam designs, develops, manufactures, markets and services chemical
mechanical planarization, or "CMP," systems used in the fabrication of
semiconductor devices and other high throughput precision surface processing
systems used in the fabrication of thin film memory disk media, semiconductor
wafers and general industrial components. In addition, the Company markets and
distributes polishing liquids (or slurry) and parts and expendables used in its
customers' manufacturing processes. The Company's array of processing systems
includes polishing, grinding, lapping and pre-deposition cleaning equipment. The
process steps performed by the Company's equipment are an integral part of and
occur repeatedly throughout the fabrication cycles of advanced semiconductors,
thin film memory disk media and semiconductor wafers. Major customers of the
Company include AMD, Akashic, Hewlett-Packard, IBM, Komag, MEMC, Mitsubishi
Siltec, Motorola, Rockwell International, Seagate, Siemens and Wacker Siltronic.
 
     Semiconductor and thin film memory disk manufacturers are rapidly adopting
new technologies in response to increasing demand by end users for improved
system performance and processing capacity and new features in computing and
other electronics applications. Semiconductor device manufacturers are producing
devices with smaller geometries and multi-level metal processes. Similarly, thin
film memory disk media manufacturers are continually increasing the density of
disk media by increasing coercivity (magnetic density) and reducing head flying
heights in order to satisfy end user demand for greater storage capacity. In
order to meet these evolving specifications, both semiconductor and thin film
memory disk manufacturers must tighten tolerances and improve certain surface
characteristics of their products. These tightened tolerances necessitate
improvements in the semiconductor and thin film memory disk media manufacturing
processes in order to increase planarity (flatness) and provide a number of new
surface characteristics.
 
     The Company currently offers the Auriga, a multiple head, two polishing
table CMP system for use in the manufacture of advanced semiconductor devices.
In addition, the Company has recently introduced the Auriga-C, which integrates
technology from the Company's Capella, its post-CMP cleaning system. The
integration of post-CMP cleaning to CMP polish is known as "dry-in/dry-out"
capability and results in polished, cleaned and dry wafers. The Company has also
recently introduced the Altair, an in situ end-point detection system, which is
designed to measure precisely the actual remaining film thickness on a wafer
during the CMP polishing process. Deliveries of the Auriga-C for revenue are
expected to begin in the second quarter of fiscal 1998. The Company's CMP
systems are designed to provide high throughput, low cost of ownership and
process flexibility. The objective of CMP is to reestablish a flat or planar
surface that has been degraded by prior deposition steps to a point where it is
not possible or feasible to deposit additional levels without first restoring
the surface to a planar condition. Reestablishing a planar surface allows
semiconductor device manufacturers to produce denser, more complex devices by
allowing the addition of a greater number of metal levels and can lead to
significant yield and reliability improvements for the device manufacturer.
Because of the depth of focus limitations of existing photolithography
equipment, global planarization becomes particularly important for devices with
design geometries of 0.35 micron or less and three or more metal levels.
According to Dataquest Incorporated, the CMP polishing equipment market was
estimated at $316 million in 1996 and it currently projects the market to be
approximately $1.2 billion in the year 2001.
 
     The Company's strategy is to establish and maintain market leadership in
high throughput surface processing of advanced semiconductors, thin film memory
disk media, semiconductor wafer and other high value-added products. The Company
employs dedicated business units focusing on each such market. The Company
provides an entire processing solution including process expertise, training,
cooperative development, slurry and expendables, along with equipment. During
the Company's fiscal years ended May 31, 1995, 1996 and 1997, 54.5%, 78.5% and
84.8%, respectively, of the Company's total revenue was derived from the
 
                                        3
<PAGE>   5
 
sale of capital equipment, parts and expendables (including commissions) and
45.5%, 21.5% and 15.2%, respectively, was derived from the sale of slurry and
slurry components.
 
     The Company owns a 50% interest in SpeedFam Co., Ltd., a joint venture that
conducts operations in the Far East (together with its subsidiaries and joint
ventures, the "Far East Joint Venture"). Generally, the Far East Joint Venture
designs, produces and markets in the Far East equipment similar to that produced
by the Company in the U.S. The Far East Joint Venture, which the Company
accounts for on the equity method, has had a substantial influence on the
results of operations of the Company in the past.

</TABLE>
 
     The Company reported total revenue of $53.8 million, up 35.5% from the
$39.7 million reported for the same period a year ago. Backlog at the end of the
first quarter was $68.3 million, up from $58.9 million a quarter earlier and
from $41.4 million a year ago.
 
     Net earnings were $5.6 million, up 37.6% from $4.0 million a year earlier.
Net earnings per share were $0.39, compared with $0.36 for the first quarter of
fiscal 1997. This comparison includes the effect of a 26.3% increase in weighted
average shares outstanding following the Company's Common Stock offering in
February 1997.
 
     For the first quarter of fiscal 1998, the equipment, parts and expendables
segment of the Company's business contributed revenue of $43.8 million, or 84.4%
of net sales, up from $31.2 million, or 82.0%, a year earlier. The slurries
segment (polishing liquids and abrasives) accounted for $8.1 million, or 15.6%
of net sales, compared with $6.8 million, or 18.0%, for the first quarter of
fiscal 1997.

     Sales of CMP systems to the semiconductor device market generated $30.7
million, or 57.0% of total revenue, nearly double the $16.3 million, or 41.0% of
total revenue, reported a year earlier. The Company shipped 14 Auriga CMP
systems during the quarter.
 
     Revenue from the thin film memory disk media market accounted for $16.2
million, or 30.1% of total revenue, compared with $16.2 million, or 40.8%, for
the first quarter of fiscal 1997. Although overall sales to this market were
flat with the prior year, equipment sales declined due to general overcapacity
in the memory disk industry and increased competition, which the Company expects
to continue for at least the next several quarters.
 
     Sales to the silicon wafer and industrial components markets contributed
revenue of $6.9 million, or 12.9% of total revenue, compared with $7.2 million,
or 18.2%, a year ago.
 
     The Company's commission revenue on sales of equipment produced by the Far
East Joint Venture for the silicon wafer and thin film memory disk media markets
in the United States and Europe totaled $1.9 million, compared with $1.7 million
for the first quarter of fiscal 1997.
 
     The Company's overall gross margin for the first quarter of fiscal 1998
improved to 42.7% from 35.1% the prior year. This increase was due to the
continued shift in the revenue mix to higher margin CMP systems.
 
     Research, development and engineering expenses were $6.8 million, or 12.6%
of total revenue, up from $3.8 million, or 9.5%, a year earlier. This increase
reflected the Company's significant investment in dry-in/dry-out and end-point
detection capabilities for its CMP systems; upgrading a key product in the
memory disk polishing market; and various process technologies for the
semiconductor device, thin film memory disk media and silicon wafer markets.
 
     Selling, general and administrative expenses were $9.4 million, or 17.4% of
total revenue, compared with $6.8 million, or 17.1%, a year ago. The percentage
increase was due primarily to higher commissions paid to the Far East Joint
Venture for sales of CMP systems manufactured in the United States, and
continued investments in the Company's sales, support and administrative
infrastructure.
 
     As a result of revenue growth and gross margin improvement, the Company's
first quarter operating profit was $6.9 million, or 12.7% of total revenue, up
from $3.4 million, or 8.5%, a year earlier. Earnings from consolidated companies
were $4.8 million, more than double the $1.9 million reported for the first
quarter of fiscal 1997.
 
     The Company's equity in the net earnings of its joint ventures was $729,000
for the first quarter, down from $2.2 million a year ago, as a result of
decreased net earnings of the Far East Joint Venture. The Far East Joint Venture
recently adopted an aggressive pricing strategy designed to gain market share
for its new automated disk polishing systems. Although the Far East Joint
Venture expects this gross margin pressure to continue to negatively impact the
Far East Joint Venture's earnings for at least the near term, the Far East Joint
Venture believes that this pricing strategy represents an important strategic
investment.

                                  RISK FACTORS
 
     The Common Stock offered hereby involves a high degree of risk. In addition
to the other information included or incorporated by reference in this
Prospectus, the following factors should be considered carefully in evaluating
the Company and its business before purchasing shares of Common Stock offered
hereby. Certain statements in this Prospectus, including without limitation
certain of those contained in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Industry
Background, -- The SpeedFam CMP Solution, -- SpeedFam Strategy" and -- Research,
Development and Engineering -- Product Development" constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. Such forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause the actual results, performance
or achievements of the Company to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements. Factors that could cause or contribute to such
differences include, but are not limited to, those discussed below.
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
     The Company's quarterly operating results have historically and may in the
future vary significantly due to a number of factors. Factors that may influence
the Company's operating results in a given quarter include: (i) customer demand,
such as economic conditions in the semiconductor and memory disk industries,
market acceptance of products of both the Company and its customers, changes in
product mix, and the timing, cancellation or delay of customer orders and
shipments; (ii) the quarterly operating results of the Company's joint ventures,
which the Company accounts for on the equity method; (iii) new product
development, such as increased research, development and engineering, as well as
marketing expenses associated with new product introductions, including the
effect of transitioning to new or enhanced products, and the Company's ability
to introduce new products and technologies on a timely basis; (iv) competition,
such as competitive pressures on prices of the Company's products and the
introduction or announcement of new products by competitors; (v) manufacturing
and operations, such as fluctuations in availability and cost of raw materials
and production capacity; (vi) fluctuations in foreign currency exchange rates;
and (vii) sales and marketing, such as concentrations of customers, and
discounts that may be granted to certain customers; as well as other factors,
such as levels of expenses relative to revenue levels, personnel changes and
generally prevailing economic conditions.
 
     The Company expects that sales of equipment to the thin film memory disk
market will be significantly lower for at least the next several quarters as
compared to prior fiscal years for a number of reasons, including a general
overcapacity in the memory disk industry and increased competition.
 
     In addition, in fiscal 1997, the equity in net earnings of affiliates
attributable to the Company's joint ventures increased substantially, primarily
as a result of increased earnings of the Far East Joint Venture attributable to
strong demand for products sold to the thin film memory and semiconductor
industries. However, the Far East Joint Venture recently adopted an aggressive
pricing strategy designed to gain market share for its new automated disk
polishing systems. The Far East Joint Venture expects this gross margin pressure
to continue to negatively impact the Far East Joint Venture's earnings for at
least the near term. As a result of the foregoing and for other reasons, the
Company does not expect earnings of the Far East Joint Venture to grow in its
next fiscal year and expects that such earnings will be the same as or lower
than in fiscal 1997. Any decline in earnings of the Far East Joint Venture could
have a material adverse effect on the results of operations of the Company.
 
     Historically, a disproportionate share of the Company's revenue and
operating profit has been attributable to the last two quarters of the Company's
fiscal year, primarily the fourth quarter. In particular, the Company typically
experienced a decline in revenues and operating profit from the fourth fiscal
quarter to the first fiscal quarter of the succeeding year. The Company believes
that this decline was primarily due to the seasonal buying patterns of its
customers. However, the Company anticipates that this historical pattern may be
moderated by increased sales of its CMP systems.
 
                                        7
<PAGE>   9
 
     During a given quarter, a significant portion of the Company's revenue may
be derived from the sale of a relatively small number of machines and systems.
Accordingly, a small change in the number of machines and systems actually
shipped may cause significant changes in operating results. Moreover, customers
may cancel or reschedule shipments, and production difficulties could delay
shipments. In addition, because of the significantly different gross margins
attributable to the Company's two segments, changes in product mix may cause
fluctuations in operating results. Further, the lengthy sales cycle for certain
of the Company's capital equipment may result in the Company incurring
significant expenses prior to the receipt of customer orders. In addition, the
introduction of new products has in the past contributed, and may continue to
contribute, to fluctuations in quarterly operating results. These same factors
also could materially and adversely affect annual results of operations. In
addition, the need for continued investment in research and development,
marketing and customer support limits the Company's ability to reduce expenses
in response to downturns in the industries it serves.
 
DEPENDENCE ON CMP SYSTEMS
 
     The Company's CMP systems accounted for 7.9%, 34.7% and 50.2% of net sales
for fiscal 1995, 1996 and 1997, respectively. The Company believes that its
future growth, if any, depends in large part upon its ability to grow revenue
attributable to its CMP systems and technology. Revenue growth attributable to
the Company's CMP systems depends upon numerous factors, including cost of
ownership, throughput, process flexibility, performance and reliability and
availability of customer support. The Company intends to periodically develop
and introduce enhanced versions of its CMP system. Failure to continually
enhance the Company's CMP system may impact its ability to grow revenue
attributable to its CMP systems. In addition, the number of suppliers for
polishing pads used in the CMP process is limited and an insufficient supply of
such products could adversely impact or impede the Company's revenue growth from
its CMP systems. There can be no assurance that the Company will be successful
in growing revenue attributable to its current CMP systems, or any future
enhanced version of the systems. The failure of the Company to accomplish these
objectives would have a material adverse effect on the Company. See
" -- Competition," "-- Dependence on New Product Development; Rapid
Technological Change."
 
DEPENDENCE ON NEW PRODUCT DEVELOPMENT; RAPID TECHNOLOGICAL CHANGE
 
     The Company believes that its future success will depend, in part, on its
ability to enhance existing products and processes and develop and manufacture
new products and processes. The markets in which the Company and its customers
compete are characterized by evolving industry standards and frequent
improvements in products and services. To compete effectively in such markets,
the Company must continually improve its products and its process technologies
and develop new technologies and products that compete effectively on the basis
of price and performance. The Company expects to continue to make significant
investments in research, development and engineering. There can be no assurance
that the Company will be able to improve its existing products and its process
technologies or develop new products and technologies. The Company intends to
continually develop and introduce enhanced versions of its CMP system and post-
CMP cleaning system. The Company has recently introduced the Auriga-C, an
enhanced version of the Company's Auriga system, which integrates technology
from the Company's Capella, its post-CMP cleaning system, thereby providing a
dry-in/dry-out system. The Company has also recently introduced the Altair, an
in situ end-point detection system. There can be no assurance that the Company's
development of new or enhanced products, such as the Auriga-C, will be
cost-effective or introduced in a timely manner or accepted in the marketplace.
Failure by the Company to develop or introduce new products and product
enhancements in a timely manner would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     Due to the complexity of the Company's products, significant delays can
occur between a system's introduction and the commencement of commercial
shipments. The Company has from time to time experienced delays in the
introduction of, and certain technical and manufacturing difficulties with,
certain of its systems and enhancements, and may experience such delays and
technical and manufacturing difficulties in future introductions or volume
production of new systems or enhancements. The Company has had limited
 
                                        8
<PAGE>   10
 
experience with the production of the Auriga-C and may encounter difficulties in
its production. Further, the Auriga-C has only recently begun testing in the
Company's laboratories and has not yet been shipped to customers for evaluation.
Deliveries of the Auriga-C for revenue are expected to begin in the second
quarter of fiscal 1998. As with any new product introduction, there are risks
that final customer acceptance may take longer than scheduled. The Company may
also incur substantial unanticipated costs to ensure the functionality and
reliability of its future product introductions early in the product's life
cycle, including with respect to the Auriga-C. If new products experience
reliability or quality problems, the Company could encounter a number of
problems, including delayed shipments, reduced orders, higher manufacturing
costs, delays in collection of accounts receivable and additional service and
warranty expenses, all of which could materially adversely affect the Company's
business and results of operations. In addition, in the event the Company does
not manage product transitions successfully, announcements or introductions, or
the perception that such events are likely to occur, by either the Company or
its competitors could adversely affect sales of existing Company products. See
"-- Dependence on CMP Systems," "-- Dependence on Key Customers" and
"Business -- Research, Development and Engineering."
 
CYCLICAL NATURE OF THE COMPANY'S BUSINESS
 
     The Company's business depends substantially on the capital expenditures of
semiconductor and thin film memory disk media manufacturers, which, in turn,
depend upon the current and anticipated market demand for memory disks and
semiconductor devices. Sales of capital equipment to these manufacturers are
expected to continue to represent a significant portion of the Company's total
revenue. These industries are highly cyclical and have historically experienced
periodic downturns characterized by oversupply and weak demand, which often have
a material adverse effect on the acquisition of capital equipment and other
products used in the manufacturing process, including products offered by the
Company. These downturns generally have materially adversely affected the
business and operating results of capital equipment suppliers, including the
Company. The semiconductor and thin film memory disk industries have recently or
are currently experiencing downturns which have led many semiconductor and
memory disk manufacturers to delay or cancel capital expenditures. To the extent
that downturns cause the Company's customers to postpone or cancel orders, the
Company's business and results of operations will be materially adversely
affected.
 
     Sales of the Company's capital equipment depend, in large part, upon the
decision of a prospective customer to increase manufacturing capacity or respond
to advances in technology by upgrading or expanding existing manufacturing
facilities or constructing new manufacturing facilities, all of which typically
involve a significant capital commitment. Certain of the Company's capital
equipment have lengthy sales cycles while the customer evaluates and receives
approvals for the purchase of the Company's systems and completes the upgrading
or expansion of existing facilities or the construction of new facilities. The
Company may expend substantial funds and management effort during the sales
cycle. The cyclicality and rapid technological change present in certain of the
industries served by the Company may also cause prospective customers to
postpone decisions regarding major capital expenditures, including purchases of
the Company's equipment. In addition, the need for continued investment in
research and development, marketing and customer support limits the Company's
ability to reduce expenses in response to downturns in the industries it serves.
 
COMPETITION
 
     The Company's markets are highly competitive. In each of the markets the
Company serves, the Company faces intense competition from established
competitors, some of which have substantially greater financial, engineering,
manufacturing and marketing resources, and, in some markets, greater name
recognition than the Company, as well as long-standing customer relationships.
Further, the Company believes that its competitors vary by geographic region. In
the CMP market, the Company faces significant competition from current
competitors and any others that may enter this market in the future. IPEC
currently has the largest installed base of CMP equipment. Other companies in
this market are in various stages of development or sale of CMP machines.
Specifically, Applied Materials, a large semiconductor capital equipment
supplier with significant resources, has introduced a multiple head CMP machine
and IPEC has begun shipments of
 
                                        9

multiple head CMP systems. Ebara, a Japanese capital equipment manufacturer, has
begun shipments of a multiple head, dry-in/dry-out system, primarily in the Far
East. In addition, certain of the Company's competitors have longer-standing
relationships than the Company with particular customers, including
semiconductor device manufacturers. These longer-standing relationships may make
it more difficult for the Company to sell its CMP systems to such device
manufacturers. Consolidation among CMP equipment suppliers or the acquisition of
one or more CMP equipment suppliers by large, established suppliers of non-CMP
capital equipment to semiconductor device manufacturers or others could
materially adversely affect the Company's ability to compete and could have a
material adverse effect on the Company's results of operations. In the thin film
memory disk and semiconductor wafer equipment markets, the Company competes with
a relatively few significant competitors.
 
     In order to remain competitive, the Company will be required to make a high
level of investment in research, development and engineering, marketing and
customer service and support. There can be no assurance that the Company will
have sufficient resources to make such investments or, even if they are made,
that the Company's products will be competitive given technological advances by
competitors or changes in processing technology in the industries the Company
serves. In the past, competitors of the Company have developed and marketed
products having similar design and functionality to the Company's products. The
Company's competitors can be expected to improve the performance of their
products and to introduce new products with competitive price/performance
characteristics. The Company's competitors may also increase their efforts to
gain and retain market share through competitive pricing. These competitive
pressures may necessitate price reductions by the Company or render the Company
less competitive.
 
     In the memory disk slurry market, the Company competes primarily with
Praxair, a large chemical company. The Company has experienced intense
competition in the sale of slurry from Praxair, which manufactures and sells its
own products. In response, the Company has in the past reduced its prices. At
the same time, the supplier of substantially all of the Company's slurry, Fujimi
Incorporated, a Japanese company, has raised the prices paid by the Company for
slurry. As a result, in recent years the Company has experienced a decline in
gross margins in the sale of slurry. Slurry has historically comprised a
significant portion of the Company's total revenue, and in fiscal 1995, 1996 and
1997, accounted for 43.1%, 19.7% and 13.5%, respectively, of total revenue. The
Company expects that competition in the slurry market will remain intense in the
future. In addition, fluctuations in exchange rates have in the past resulted,
and may in the future result, in increases in the costs of slurry for the
Company. Decreased slurry selling prices or increased slurry costs could have a
material adverse effect on the Company's results of operations. See "-- Sole or
Limited Sources of Supply," "Business -- Manufacturing and Suppliers,"
"-- Competition" and "-- International Business."
 
RELIANCE ON THE PERFORMANCE OF AND RELATIONSHIP WITH FAR EAST JOINT VENTURE
 
     The Company owns a 50% interest in SpeedFam Co., Ltd., a joint venture that
conducts operations in the Far East (together with its subsidiaries and joint
ventures, the "Far East Joint Venture"). During fiscal 1995, 1996 and 1997, the
Company's share of the net earnings of the Far East Joint Venture was $1.1
million, $4.8 million and $5.5 million, respectively, representing 66.9%, 40.3%
and 27.3%, respectively, of the Company's net earnings. The Company accounts for
the Far East Joint Venture on the equity method. During fiscal 1995, 1996 and
1997, 4.6%, 5.2% and 7.2%, respectively, of the Company's total revenue was
attributable to commissions earned by the Company on the distribution in the
U.S. and Europe of products of the Far East Joint Venture. The Far East Joint
Venture has paid dividends to the Company in the past and may continue to do so
in the foreseeable future, but is expected to reinvest substantially all of its
earnings back into its business. At May 31, 1997, the Company's equity interest
in the Far East Joint Venture was $20.4 million, representing 9.9% of the
Company's total assets and 13.0% of shareholders' equity. The results of
operations of the Company in the past have been substantially influenced by the
results of operations of the Far East Joint Venture and can be expected to
continue to be so influenced in the future. The term of the joint venture is
indefinite. In the event that either the Company or its joint venture partner
desires to sell its interest in the Far East Joint Venture, it must first offer
its interest to the other party. The Company believes that for a number of
reasons, including the fact that the Company does not own a controlling interest
in the Far East Joint
 
                                       10
<PAGE>   12
 
Venture, the Company's ability to effect a sale of its interest is limited and
the proceeds the Company would receive from a sale of its interest in the Far
East Joint Venture may be reduced.
 
     Certain of the equipment produced and sold by the Far East Joint Venture is
similar to that produced in the U.S. by the Company. In addition, the Far East
Joint Venture produces and sells cleaning and automated polishing machines for
the thin film memory disk market and polishing machines for the semiconductor
wafer market, including machines that are distributed by the Company in the U.S.
and Europe. Each of the Company and the Far East Joint Venture generally sell to
customers in the same end markets. Because of the similarity between the
business of the Company and that of the Far East Joint Venture, substantially
all of the risks described herein with respect to the Company's business are
also generally applicable to the business of the Far East Joint Venture. In
addition, the Far East Joint Venture is subject to certain economic and
political risks associated with conducting international business, as most sales
by the Far East Joint Venture occur outside the U.S. and a material portion of
the products sold by the Far East Joint Venture are shipped across international
borders. Also, the business of the Far East Joint Venture is substantially
influenced by general economic conditions in the regions in which it operates,
particularly Japan. A majority of the net sales of the Far East Joint Venture
are generated in Japan. Periods of weak or declining economic conditions in
Japan, such as those recently experienced, could have a material adverse effect
on the business and operating results of the Far East Joint Venture and, in
turn, the Company.
 
     The Company does not have the legal right or practical ability to control
the Far East Joint Venture. The historic business relationship between the
Company and its joint venture partner has been based to a significant degree on
personal relationships of the individuals involved. If those individuals or
relationships were to change, it could result in a material adverse effect on
the relationship between the Company and the Far East Joint Venture and, in
turn, on the results of operations of the Company. In many instances, management
decisions regarding the relationship between the Company and the Far East Joint
Venture have not been made on the basis of arms-length negotiations. Instead,
the business of the Far East Joint Venture and the business relationship between
the Company and the Far East Joint Venture have been influenced by personal
relationships between members of management of the two joint venture partners,
the previous dealings of the entities and an underlying business intention to
improve the mutual interests of the Company and the Far East Joint Venture, even
if one party in a particular circumstance could negotiate a transaction with
more favorable terms with a third party. For example, even though the agreements
between the parties originally called for the payment of royalties for licensed
technology, the parties amended the agreements to remove the royalty
requirements, and it is not currently anticipated that either the Company or the
Far East Joint Venture will pay royalties to the other in connection with the
transfer of technology in the foreseeable future, including with respect to the
Company's CMP technology. Makoto Kouzuma, President and Chief Executive Officer
of the Company, is the Executive Vice President and General Manager of SpeedFam
Co., Ltd. and is responsible for its day-to-day operations and therefore spends
a significant portion of his time engaged in its business. These
responsibilities have placed a heavy demand on Mr. Kouzuma's time, and have
precluded him from spending all of his time with either the Company or the Far
East Joint Venture. Both James N. Farley, the Chairman of the Company, and Mr.
Kouzuma serve as directors of the Far East Joint Venture and have management
responsibilities in connection with affiliates of the Far East Joint Venture.
Mr. Kouzuma is compensated directly by the Far East Joint Venture for such
services. As a result of this relationship between the Company and the Far East
Joint Venture, management decisions in particular instances may tend to favor
the Far East Joint Venture relative to decisions that would be made if the Far
East Joint Venture were an unaffiliated third party.
 
     The Company's partner in the Far East Joint Venture is a privately-held
Japanese corporation that supplies products to the automotive industry. Given
the differences in the companies' ownership structure and products, there can be
no assurance that the Company and its Far East Joint Venture partner will have
similar interests with respect to the financial performance of the Far East
Joint Venture.
 
     Pursuant to the agreement establishing the Far East Joint Venture, each of
the Company and its joint venture partner has agreed not to manufacture or sell
in Japan products similar to those sold by the Far East Joint Venture. Further,
the Company has granted to the Far East Joint Venture the exclusive right to
manufacture and sell products similar to those manufactured and distributed by
the Company in Japan,
 
                                       11
<PAGE>   13
 
Korea, Taiwan, Hong Kong, China, India, the Philippines, Thailand, Vietnam,
Malaysia, Singapore and Indonesia and such other countries as the parties may
agree to from time to time. As a result, the Company does not have the legal
right to itself market products, including its CMP system, in those countries
that are served by the Far East Joint Venture. The Company is therefore
dependent upon the Far East Joint Venture to market its CMP system in the
territories served exclusively by the Far East Joint Venture.
 
     The Company and the Far East Joint Venture share technology and expertise
and each is dependent upon the other to protect any shared proprietary
information. There can be no assurance that the sharing of technology and
trademarks by the Company with the Far East Joint Venture will not result in the
release of proprietary information, which could have a material adverse effect
upon the Company.
 
     The Company believes that, to date, the relationship between the Company
and its joint venture partner has been good. However, no assurance can be given
that the relationship will continue to be satisfactory or that the joint venture
will not terminate. In addition, changes in management of the Company or its
joint venture partner could negatively impact the relationship between the joint
venture partners. Any decline in the Far East Joint Venture's results of
operations, termination of the joint venture or difficulties between the Company
and its joint venture partner would have a material adverse effect on the
Company's business, prospects and results of operations and financial condition.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business -- Joint Ventures," "Joint Venture Arrangements -- Far
East Joint Venture" and the consolidated financial statements of SpeedFam Co.,
Ltd.
 
SOLE OR LIMITED SOURCES OF SUPPLY
 
     The Company relies to a substantial extent on outside suppliers to
manufacture many of the components and subassemblies used in the Company's
capital equipment, some of which are obtained from a single supplier or a
limited group of suppliers. The Company's reliance on outside suppliers
generally, and a sole or a limited group of suppliers in particular, involves
several risks, including a potential inability to obtain an adequate supply of
required components and reduced control over quality, pricing and timing of
delivery of components. In the past, the Company has experienced delays in
receiving materials from suppliers, sometimes resulting in delays in the
delivery of products by the Company. Such delays, or other significant supplier
or supply quality issues, may occur in the future, which could result in a
material adverse effect on the Company. Because the manufacture of certain of
these components and subassemblies is specialized and requires long lead times,
there can be no assurance that delays or shortages caused by suppliers will not
reoccur. Any inability to obtain adequate deliveries, or any other circumstance
that would require the Company to seek alternative sources of supply or to
manufacture such components internally, could delay shipment of the Company's
products, increase its cost of goods sold and have a material adverse effect on
the Company's business and results of operations. See "Business -- Manufacturing
and Suppliers."
 
MANAGEMENT OF GROWTH
 
     The Company has recently experienced a period of rapid growth. The number
of employees of the Company has increased 163% from 195 at May 31, 1995 to 513
at May 31, 1997. This growth has resulted in, and is expected to continue to
create, new and increased responsibilities for management personnel, as well as
added pressures on the Company's operating and financial systems. If the Company
is required to manufacture its systems in larger volumes, it may become more
difficult for the Company to maintain its standards of quality and reliability,
and delivery times for its systems may grow longer. Further, if the Company were
to be unable to expand its manufacturing capacity to meet demand, orders in
backlog may be cancelled or lost to competitors. The Company currently plans to
hire a significant number of additional employees during fiscal 1998. The
Company's ability to manage future growth effectively and accomplish its overall
goals will depend on its ability to hire additional management, technical and
manufacturing personnel, to integrate its new employees into its overall
operations and culture, and to continue to improve its operational, financial
and management systems. If the Company is unable to manage growth effectively or
hire or retain qualified personnel, the Company's business and results of
operations would be materially adversely affected. See "-- Dependence on Key
Personnel," "Business -- Properties" and "-- Employees."
 
                                       12
<PAGE>   14
 
DEPENDENCE ON KEY CUSTOMERS
 
     The Company's ten largest customers accounted for, in the aggregate, 66.9%,
64.4% and 59.8% of the Company's total revenue in fiscal years 1995, 1996 and
1997, respectively. The loss of, or a significant curtailment of purchases by,
one or more of the Company's key customers would materially adversely affect the
Company's business and results of operations. One of the Company's largest
customers, Komag (a manufacturer of thin film memory disks), accounted for
20.6%, 17.8% and 10.3% of the Company's total revenue in fiscal years 1995, 1996
and 1997, respectively. Although Komag has represented a significant portion of
the Company's sales of polishing machines to the thin film memory disk market in
the past, it is not anticipated that Komag will represent as significant a
portion of such sales in the future. AMD (a manufacturer of semiconductor
devices), accounted for 12.8% of the Company's total revenue for fiscal 1997. In
addition, during fiscal 1995, Akashic (a manufacturer of thin film memory disk
media), accounted for 10.9% of the Company's total revenue. See "-- Dependence
on New Product Development; Rapid Technological Change," "Business -- Customers"
and "-- Sales and Marketing."
 
     The Company expects that sales of its products to relatively few customers
will continue to account for a high percentage of its revenue in the foreseeable
future. In addition, in certain of the markets the Company targets, such as the
CMP, thin film memory disk and semiconductor wafer markets, there are relatively
few potential customers. Generally, the Company has not entered into long-term
agreements with its customers. In addition, as purchases related to a particular
new, expanded or upgraded facility are completed, sales to that customer may
decrease sharply. If completed orders are not replaced on a timely basis by new
orders from the same or other customers, the Company's revenue and results of
operations could be materially adversely affected. See "-- Fluctuations in
Quarterly Operating Results" and "Business -- Customers."
 
INTERNATIONAL BUSINESS
 
     In fiscal 1995, 1996 and 1997, 17.3%, 21.7% and 31.2%, respectively, of the
Company's total revenue was attributable to sales outside the United States. In
addition, under certain circumstances, products sold to U.S. customers are
shipped to those customers' overseas facilities. The Company expects that
international sales will continue to represent a significant portion of its
total revenue. Sales to customers outside the United States are subject to
numerous risks, including exposure to currency fluctuations, the imposition of
government controls, the need to comply with a wide variety of foreign and U.S.
export laws, political and economic instability, trade restrictions, changes in
tariffs and taxes typically associated with foreign sales, the greater
difficulty of administering business overseas and general economic conditions.
In addition, the laws of certain foreign countries may not protect the Company's
intellectual property to the same extent as do the laws of the United States.
The Company also purchases in yen certain equipment from the Far East Joint
Venture that the Company then sells in the U.S. and Europe. Moreover, slurries
marketed and distributed by both the Company and Fujimi Corporation, the
Company's joint venture with Fujimi Incorporated, a Japanese company (the
"Fujimi Joint Venture") are purchased in yen from Fujimi Incorporated, a
Japanese company. Fluctuations in exchange rates have in the past resulted, and
may in the future result, in increases in the cost to the Company of such
products. Also, because the value of the net assets of the Company's foreign
subsidiaries and its equity interest in the Far East Joint Venture fluctuate
based upon exchange rates and because the Company does not hedge the value of
such net assets, fluctuations in exchange rates may have an adverse effect on
the Company's shareholders' equity. See "-- Reliance on the Performance of and
Relationship with Far East Joint Venture" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's success depends to a significant extent upon certain senior
management and technical personnel. The loss of the services of one or more of
these key persons could have a material adverse effect on the Company. Although
the Company has employment agreements with certain of these key employees, such
agreements are terminable at will by the employee. The Company's future success
will depend in large part upon its ability to attract and retain highly skilled
technical, managerial, and marketing personnel. Competition for such personnel
in the Company's industry is intense and the companies with which the Company
 
                                       13
<PAGE>   15
 
competes are often larger and more established than the Company. There can be no
assurance that the Company will be successful in attracting and retaining
qualified personnel. See "Business -- Employees" and "Management."
 
INTELLECTUAL PROPERTY RIGHTS
 
     The Company currently holds numerous United States patents and additional
foreign patents in Japan and several Asian and European countries and has
numerous United States and foreign patent applications pending. In addition, the
Company believes that such factors as continued innovation, technical expertise
and know-how of its personnel and other factors are also important. There can be
no assurance that the Company will be able to protect its technology or that
competitors will not be able to develop similar technology independently. No
assurance can be given that the claims allowed on any patents held or acquired
by the Company will be sufficiently broad to protect the Company's technologies.
In addition, no assurance can be given that any existing or future patents
issued to the Company will not be challenged, invalidated, or circumvented or
that the rights granted thereunder will provide competitive advantages to the
Company. In that event, the Company's results of operations could be adversely
affected. Moreover, the Company may choose to incur significant costs in an
attempt to defend its patent rights.
 
     In addition, although the Company believes that its products do not
infringe any valid existing proprietary rights of others, there can be no
assurance that third parties will not assert infringement claims in the future.
In the CMP market the Company serves, there are a number of patents relating to
the CMP process held by third parties. Accordingly, the Company, as a CMP
equipment manufacturer, may be required to attempt to obtain licenses from the
holders of one or more of such patents, which may impede the use of CMP
technology by the Company. There also may be pending patent applications or
issued patents of which the Company is not aware, and which would require the
Company to license or challenge such patents, at significant expense to the
Company. There can be no assurance that any such license would be available on
acceptable terms, if at all, or that the Company would prevail in any such
challenge. See "Business -- Intellectual Property."
 
ENVIRONMENTAL REGULATIONS
 
     The Company is subject to a variety of federal, state and local laws, rules
and regulations relating to the use, storage, discharge and disposal of
hazardous chemicals used in research and development. In addition, a number of
slurries and other materials sold by the Company and used by the Company's
customers on equipment manufactured by the Company are substances subject to
such regulation. Public attention has increasingly been focused on the
environmental impact of operations that use hazardous materials. Failure to
comply with present or future regulations could result in substantial liability
to the Company. In addition, new laws, rules and regulations could be adopted
that could result in significant expense to the Company in the conduct of its
business.
 
CONTROL BY EXISTING SHAREHOLDERS
 
     Following the offering, Mr. Farley, his spouse and adult children will, in
the aggregate, beneficially own approximately 24.2% of the Company's outstanding
shares (approximately 23.7% assuming the full exercise of the Underwriters' over
allotment option). Further, following this offering, the Company's executive
officers, directors and Mr. Farley's spouse, a principal shareholder (exclusive
of shares beneficially owned by Mr. Farley's adult children) will, in the
aggregate, beneficially own approximately 22.8% of the Company's outstanding
shares of Common Stock (approximately 22.3% assuming the full exercise of the
Underwriters' over allotment option). As a result, these shareholders, if acting
together, would be able to significantly influence the outcome of most matters
requiring approval by the shareholders of the Company, including the election of
the directors and other actions by shareholders with respect to the business and
affairs of the Company. In addition, the voting power of these shareholders
under certain circumstances could have the effect of delaying or preventing a
change in control of the Company. See "Management," "Principal and Selling
Shareholders" and "Description of Capital Stock."
 
                                       14
<PAGE>   16
 
POSSIBLE ISSUANCE OF PREFERRED STOCK
 
     The Board of Directors has authority to issue up to 1,000,000 shares of
Preferred Stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of those shares without any further vote or action by
the shareholders. The rights of the holders of the Common Stock will be subject
to, and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. The issuance of Preferred Stock, while
providing flexibility in connection with possible acquisitions and other
corporate purposes, could have the effect of making it more difficult for a
third party to acquire a majority of the outstanding voting stock of the
Company, thereby delaying or preventing a change in control of the Company.
Furthermore, such Preferred Stock may have other rights, including economic
rights senior to the Common Stock, and, as a result, the issuance thereof could
have a material adverse effect on the market value of the Common Stock. The
Company has no present plans to issue shares of Preferred Stock. See
"Description of Capital Stock."
 
VOLATILITY OF STOCK PRICE
 
     The market price of the Common Stock is subject to significant fluctuations
in response to the Company's operating results and other factors, including:
announcements of developments related to the Company's business; fluctuations in
the Company's order levels; general conditions in the technology industries or
the worldwide economy; announcements of technological innovations; new products
or product enhancements by the Company or its competitors; developments in
patents or other intellectual property rights; significant changes in
management; and developments in the Company's relationships with its joint
venture partners, customers, distributors and suppliers. In addition, in recent
years the stock market in general, and the shares of technology companies in
particular, have experienced extreme price fluctuations, and such extreme price
fluctuations may continue. These broad market and industry fluctuations may
adversely affect the market price of the Company's Common Stock.

                                  THE COMPANY
 
     The Company was incorporated in Illinois in 1959 as SpeedLap Corporation.
SpeedFam International, Inc. is a holding company operating through three wholly
owned subsidiaries, and also owns interests in two joint ventures. The Company
operates through SpeedFam Corporation in the U.S. ("SpeedFam U.S.") and SpeedFam
Limited ("SpeedFam U.K.") and SpeedFam GmbH ("SpeedFam Germany") in Europe.
SpeedFam International, Inc. owns 50% of each of two joint ventures, the Far
East Joint Venture and the Fujimi Joint Venture. The Far East Joint Venture
primarily produces and sells products in the Far East similar to those produced
by the Company, and the Fujimi Joint Venture sells slurries and pads in North
America.
 
     Unless the context otherwise requires, the "Company" and "SpeedFam" refer
only to SpeedFam International, Inc., an Illinois corporation, and its wholly
owned subsidiaries. The Company's principal executive offices are located at 305
North 54th Street, Chandler, Arizona 85226 and its telephone number is (602)
705-2100.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$103.2 million ($120.1 million if the Underwriters' over-allotment option is
exercised in full), after deducting the estimated underwriting discounts and
commissions and offering expenses payable by the Company. The Company will not
receive any of the proceeds from the sale of shares by the Selling Shareholders.
 
     Approximately $30.5 million of net proceeds is estimated to be used for
capital expenditures. The Company expects to use the remaining net proceeds of
this offering for working capital and for other general corporate purposes. The
Company may also use a portion of the net proceeds to fund acquisitions of
businesses, divisions of companies or technologies complementary to those of the
Company, although there are no current agreements or commitments with respect to
any such transactions. Pending such uses, the Company intends to invest the net
proceeds from this offering in short-term, interest-bearing securities. The
Company continually evaluates its financial position and financing alternatives.
The Company may, in the future, raise additional funds through bank financing
and the sale of equity securities.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
     The Company's Common Stock is traded on the Nasdaq Stock Market under the
symbol "SFAM." Public trading of the Common Stock commenced on October 10, 1995.
Prior to that time, there was no public market for the Company's Common Stock.

     On September 16, 1997, the last reported sale price of the Common Stock on
the Nasdaq Stock Market was $54 1/4 per share. As of September 2, 1997, there
were 102 holders of record of the Common Stock.
 
     The Company has never declared or paid cash dividends on its Common Stock.
The Company currently intends to retain any future earnings to finance the
growth and development of its business and does not intend to pay any cash
dividends on its Common Stock in the foreseeable future. Payment of dividends in
the future, if any, will be made at the discretion of the Board of Directors of
the Company. Such decisions will depend on a number of factors, including the
future earnings, capital requirements, financial condition and future prospects
of the Company and such other factors as the Board of Directors may deem
relevant.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     SpeedFam designs, develops, manufactures, markets and services chemical
mechanical planarization, or "CMP," systems used in the fabrication of
semiconductor devices and other high throughput precision surface processing
systems used in the fabrication of thin film memory disk media, semiconductor
wafers and general industrial components. In addition, the Company markets and
distributes parts and expendables and slurries. The Company's total revenue
consists of net sales in two business segments: (i) equipment, parts and
expendables, and (ii) slurries, as well as commissions earned on the
distribution in the U.S. and Europe of products manufactured by the Far East
Joint Venture. Sales of the Company's products are recorded upon shipment or
when the product is accepted by the customer, provided that no significant
obligations remain outstanding and collection of the related receivable is
deemed probable. The Company accrues estimated warranty and installation
expenses for each equipment and system order at the time the related sale is
recorded.
 
     Equipment, parts and expendables consist of capital equipment manufactured
by the Company, spare parts for that equipment and expendable products, such as
bearings, grinding stones, lapping plates, workpiece carriers, seals, retaining
rings, workholders and polishing pads. During fiscal year 1995, 1996 and 1997,
52.3%, 77.3% and 83.6%, respectively, of the Company's net sales was
attributable to the sale of capital equipment, parts and expendables.
Historically, the gross margin for products in this segment has been
significantly higher than that for slurries. The Company began development of
its original CMP product, the CMP-V, in 1990. The Company initiated volume
shipments of the CMP-V in 1994. Shipments of the Auriga began in the second
quarter of fiscal 1997. Through May 31, 1997, the Company had shipped 26 Auriga
systems. The Company's CMP systems accounted for 7.9%, 34.7% and 50.2% of net
sales for fiscal 1995, 1996 and 1997, respectively. The Company's CMP systems
generally have gross margins higher than those of the Company's other capital
equipment products.
 
     Slurries consist of polishing slurry and slurry components (including
vehicles and abrasives) used in surface processing. During fiscal year 1995,
1996 and 1997, 47.7%, 22.7% and 16.4%, respectively, of the Company's net sales
was attributable to sales of slurries. Substantially all of the slurries sold by
the Company are manufactured by Fujimi Incorporated. Historically, the gross
margin for slurries has been significantly lower than that for equipment, parts
and expendables. In recent years, the Company has experienced severe competitive
pressure in the sale of slurries and has been required to reduce prices. In
addition, the Company has experienced increased slurry costs.
 
     Commissions from affiliate ("commissions") consist primarily of revenue
derived from the distribution by the Company in the U.S. and Europe of products
manufactured by the Far East Joint Venture for which the Company acts as sales
agent. Certain capital equipment marketed and distributed by the Company is
produced solely by the Far East Joint Venture. The Company distributes such
products throughout the U.S. and Europe and receives commissions thereon. Such
amount reflects the difference between the imported equipment's cost to the
Company and sales price to the customer. For fiscal 1995, 1996 and 1997,
commissions accounted for 4.6%, 5.2% and 7.2%, respectively, of total revenue.
Commissions are subject to foreign exchange rate fluctuations which can
significantly impact operating profit margins.
 
     In fiscal 1995, 1996 and 1997, 17.3%, 21.7% and 31.2%, respectively, of the
Company's total revenue was attributable to sales outside the United States. In
particular, in fiscal 1997, 14.2% of the Company's total revenue was
attributable to sales made to European markets and 17.0% was attributable to
sales to markets in the Far East.
 
     The Company generally enters into foreign exchange contracts to hedge
certain firm commitments denominated in foreign currencies, principally in yen.
The terms of the contracts are rarely more than one year. Currency exchange rate
variations have had an immaterial effect on the Company's results of operations
for the periods presented. The results of operations of the Company's foreign
subsidiaries and its equity in the net earnings of the Far East Joint Venture
are translated for financial statement purposes based upon average exchange
rates during the period covered. As a result, fluctuations in exchange rates may
have an adverse
 
                                       20
<PAGE>   22
 
effect on the Company's results of operations. Net assets of the Company's
foreign subsidiaries and 50% of the net assets of the Far East Joint Venture
were approximately $24.6 million at April 30, 1997 (the end of fiscal 1997 of
such entities).
 
     The Company owns a 50% interest in both the Far East Joint Venture and the
Fujimi Joint Venture. The Company's equity interest in each joint venture is
accounted for on the equity method. As a result, the Company's share of the net
earnings of the Far East Joint Venture and the Fujimi Joint Venture appear in
the "Equity in net earnings of affiliates" caption on the Company's consolidated
statements of earnings. The Far East Joint Venture and the Fujimi Joint Venture
have paid dividends in the past and may continue to do so in the foreseeable
future, but are expected to reinvest substantially all their earnings back into
their respective businesses. The Company's share of the net earnings of the Far
East Joint Venture has not in the past resulted and is not expected in the
future to result in a like effect on the cash flows of the Company. At May 31,
1997, the Company's equity interest in the Far East Joint Venture was $20.4
million, representing 9.9% of the Company's total assets and 13.0% of
shareholders' equity. The net earnings of the Company in the past have been
substantially influenced by the results of operations of the Far East Joint
Venture and can be expected to continue to be so influenced in the future. See
"Joint Venture Arrangements" and the consolidated financial statements of
SpeedFam Co., Ltd. included elsewhere herein.
 
     Historically, a disproportionate share of the Company's revenue and
operating profit has been attributable to the last two quarters of the Company's
fiscal year, primarily the fourth quarter. In particular, the Company typically
experienced a decline in revenues and operating profit from the fourth fiscal
quarter to the first fiscal quarter of the succeeding year. The Company believes
that this decline was primarily due to the seasonal buying patterns of its
customers. However, the Company anticipates that this historical pattern may be
moderated by increased sales of its CMP systems. Sales of slurries tend to be
more consistent than equipment sales on a quarterly basis.

FISCAL 1997 COMPARED WITH FISCAL 1996
 
     Net Sales.  Net sales for the fiscal year ended May 31, 1997 were $161.0
million, up 41.4% over net sales of $113.9 million in fiscal 1996. Equipment,
parts and expendables accounted for 83.6% of net sales in fiscal 1997 compared
to 77.3% in fiscal 1996. The growth in this segment was attributable to higher
sales of the Company's CMP systems to the semiconductor industry. Sales of CMP
systems totaled $80.8 million, or 50.2% of net sales, more than double the $39.5
million of CMP system sales in fiscal 1996. In addition to the
 
                                       21
<PAGE>   23
 
significant increase in CMP equipment sales to semiconductor manufacturers, net
sales for the fiscal year increased due to a higher level of sales of equipment,
parts and expendables to the thin film memory disk media market. Sales of
slurries increased to $26.3 million in fiscal 1997 from $25.8 million in fiscal
1996. However, as a percent of net sales, sales of slurries decreased to 16.4%
in fiscal 1997 from 22.7% in fiscal 1996. European sales decreased to $9.9
million in fiscal 1997 from $10.9 million in fiscal 1996.
 
     Commissions from Affiliate.  Commissions from affiliate increased to $12.4
million in the year ended May 31, 1997, compared to $6.3 million in the year
ended May 31, 1996. The increase in fiscal 1997, as compared to fiscal 1996, was
due primarily to increased demand in the silicon wafer industry for polishing
systems developed and manufactured by the Far East Joint Venture. In addition,
sales of cleaning and polishing systems, also produced by the Far East Joint
Venture, to customers in the thin film memory disk media market increased
significantly in fiscal 1997 over fiscal 1996. Commissions from affiliate also
improved over the prior year due to improved margins on import machines.
 
     Gross Margin.  In fiscal 1997, gross margin was $69.9 million, or 40.3% of
total revenue, compared to $41.5 million, or 34.5% of total revenue, in fiscal
1996. In addition to higher sales levels, gross margin has increased due to a
continuing increase in sales of higher margin equipment, particularly systems
for the planarization of semiconductor devices. In addition, higher commission
revenue contributed to the increased gross margins in fiscal 1997.
 
     Research, Development and Engineering.  In the year ended May 31, 1997,
research, development and engineering expense increased to $19.8 million, or
11.4% of total revenue, compared to $11.5 million, or 9.6% of total revenue, in
fiscal 1996. The increase in both the dollar amount and as a percent of total
revenue is a result of the continued investment in the development of the CMP
process and products for key markets, particularly for the semiconductor sector,
and the increase in the Company's field support organization throughout the
world. Such expenditures have resulted in the development and sale of the
Company's CMP systems, and the development of the Capella, the Company's
post-CMP cleaning system.
 
     Selling, General and Administrative.  In fiscal 1997, selling, general and
administrative expense increased to $28.7 million from $18.9 million in fiscal
1996. In fiscal 1997, selling, general and administrative expense increased as a
percent of total revenue to 16.5% from 15.7% in fiscal 1996. Higher levels of
spending were required to support the sales growth in fiscal 1997. This increase
in selling, general and administrative expense as a percentage of revenue
reflects continued investments in the sales and administrative infrastructure,
as well as increased commissions paid to the Far East Joint Venture as a result
of increased sales of CMP systems produced by the Company in the U.S. and
exported to Pacific Rim customers though its joint venture affiliate.
 
     Other Income (Expense).  Other expense increased to $298,000 in fiscal 1997
from $208,000 in fiscal 1996. Other income (expense) includes charges associated
with the Company's public common stock offering in the first quarter of fiscal
1997 which was subsequently canceled, interest expense, miscellaneous expenses
and interest income.
 
     Provision for Income Taxes.  The Company's effective tax rate in fiscal
1997 was 38%, compared to 39% in fiscal 1996. The Company's effective income tax
rate in fiscal 1997 differs from the Federal statutory rate primarily as a
result of state taxes, net of the U.S. federal benefit offset by the tax benefit
from a foreign sales corporation and research and development tax credits.
 
     Equity in Net Earnings of Affiliates.  For the year ended May 31, 1997,
equity in net earnings of affiliates increased to $7.1 million compared to $5.2
million in the year ended May 31, 1996. Demand continued to be strong for
products sold to the thin film memory and semiconductor wafer industries by the
Far East Joint Venture. However, due to recent competition in the sale of
equipment into the thin film memory disk market, the Company does not expect
that this historical rate of earnings growth will continue and expects that
earnings of the Far East Joint Venture during its fiscal 1998 will be the same
as or lower than in fiscal 1997. In addition, the Company's share of the net
earnings of the Fujimi Joint Venture was significantly higher than in fiscal
1996 due to increased sales and improved margins realized during fiscal 1997 on
slurry products sold by the Fujimi Joint Venture to the U.S. silicon wafer
market.

FISCAL 1996 COMPARED WITH FISCAL 1995
 
     Net Sales.  Net sales for the fiscal year ended May 31, 1996 were $113.9
million, almost double the net sales of $57.0 million reported in fiscal 1995.
Equipment, parts and expendables accounted for 77.3% of net sales in fiscal 1996
compared to 52.3% in fiscal 1995. CMP-V sales were $39.5 million and accounted
for 34.7% of net sales in fiscal 1996, up from 7.9% in fiscal 1995. In addition
to the significant increase in CMP-V sales to semiconductor manufacturers, net
sales increased due to industry growth in the thin film memory disk media and
semiconductor wafer markets. As a result, sales of related equipment, parts and
expendables also increased in fiscal 1996 over fiscal 1995. Sales of slurries as
a percent of net sales decreased to 22.7% in fiscal 1996 from 47.7% in fiscal
1995.
 
     Commissions from Affiliate.  Commissions from affiliate more than doubled
to $6.3 million in the year ended May 31, 1996, compared to $2.8 million in the
year ended May 31, 1995. The increase in fiscal 1996, as compared to fiscal
1995, was due primarily to the increasing demand from the silicon wafer industry
to meet that industry's growing requirements, and increased demand for certain
technologies developed and manufactured by the Far East Joint Venture.
 
     Gross Margin.  In fiscal 1996, gross margin was $41.5 million or 34.5% of
total revenue compared to $14.3 million or 23.9% of total revenue in fiscal
1995. In addition to higher sales levels, gross margin increased due to a
considerable shift towards higher margin products in the equipment, parts and
expendables segment, particularly the CMP-V planarization system.
 
     Research, Development and Engineering.  In the year ended May 31, 1996,
research, development and engineering expense increased to $11.5 million or 9.6%
of total revenue compared to $2.7 million or 4.6% of total revenue in fiscal
1995. The Company has committed significant resources to the continued
development of the CMP process and other related technologies. The Company
believes that increased spending in research, development and engineering,
including providing required technical support services for needs of customers,
are all major factors to continued CMP sales growth.
 
     Selling, General and Administrative.  In fiscal 1996, selling general and
administrative expense increased to $18.9 million from $9.9 million in fiscal
1995. In fiscal 1996, selling, general and administrative expense decreased as a
percent of total revenue compared to fiscal 1995 due to the significantly higher
level of sales between the same periods. However, higher levels of spending were
required to support this sales growth including additional administrative and
sales personnel, new service and sales locations, and distributor commissions to
the Far East Joint Venture on export sales from the U.S. to the Far East region.
 
     Other Income (Expense).  Other expense decreased to $208,000 in fiscal 1996
from $953,000 in fiscal 1995. In fiscal 1995, the Company incurred a $350,000
foreign exchange loss on several import equipment orders. In addition, interest
expense decreased from fiscal 1995 to fiscal 1996 due to the retirement of the
outstanding balance of a revolving line of credit and the retirement of
long-term debt payable to a former director. The remaining decrease in other
expense is due primarily to additional interest income earned on the investment
of proceeds received upon completion of the Company's initial public offering of
Common Stock in October 1995.
 
     Provision for Income Taxes.  The Company's effective tax rate in fiscal
1996 was 39%, compared to 29% in fiscal 1995. The Company's effective income tax
rate in fiscal 1996 differs from the Federal statutory rate primarily as a
result of state taxes, net of the U.S. federal benefit. The fiscal 1995
effective tax rate differs from the statutory rate primarily as a result of the
tax benefit from a foreign sales corporation.
 
     Equity in Net Earnings of Affiliates.  For the year ended May 31, 1996,
equity in net earnings of affiliates increased to $5.2 million compared to $1.2
million in the year ended May 31, 1995. The increase is primarily attributable
to a continued strong demand for products sold to the thin film memory and
semiconductor wafer industries by the Far East Joint Venture. In addition,
profits of the Far East Joint Venture have increased due to improvements in
manufacturing, cost reduction programs and a lower effective tax rate.

     The Company's results of operations may be subject to significant quarterly
variation. Certain of the Company's systems have relatively high selling prices.
This can cause quarterly variations in equipment sales and have a significant
effect on the Company's results of operations. The results of operations for a
particular quarter may also vary due to a number of factors, including market
conditions in the semiconductor device, thin film memory disk and semiconductor
wafer industries, customer delivery schedules, timing of orders, the

and cost of raw materials and the quarterly operating results of the Company's
joint ventures. Also, customers may reschedule, or in rare instances cancel
shipments, and production difficulties may delay shipments.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     For the year ended, May 31, 1997, $6.9 million in cash was provided by
operating activities primarily from net earnings. Cash from operating activities
was also provided by an increase in accounts payable and accrued expense
liabilities since the beginning of the fiscal year. Cash was used in operating
activities primarily to reduce the due to affiliates liability, income taxes
payable and to support growth in accounts receivable and inventories.
 
     The Company recently completed construction of its new corporate
headquarters and manufacturing facility in Chandler, Arizona. Total costs
incurred for the project were approximately $18.9 million.
 
     On October 26, 1995, the Company completed its initial public offering of
Common Stock. The Company issued 2,927,500 shares of Common Stock and received
proceeds of $28.3 million, net of underwriters' discounts and commissions and
offering expenses. On February 20, 1997, the Company completed a second public
offering of Common Stock. In connection therewith, the Company issued 2,500,000
shares of Common Stock and received proceeds of $77.7 million, net of
underwriters' discounts and commissions and offerings expenses. In addition, for
the year ended May 31, 1997, $1.5 million was provided by the sale of stock to
employees through the Company's Employee Stock Purchase Plan and through the
exercise of stock options.
 
     Using proceeds from the February 1997 stock offering, the Company paid off
the entire $2.8 million outstanding balance under a $22.5 million unsecured
revolving line of credit maturing April 14, 1999. As of May 31, 1997, no amounts
were outstanding on this line of credit.
 
     On August 29, 1997, the Company successfully negotiated a new unsecured
credit facility with its U.S. bank group which replaced the $22.5 million credit
facility and a $14 million term loan commitment. The new credit agreement
provides for a revolving loan facility in the amount of $60 million with a term
of three years. At August 31, 1997, no amounts were outstanding on this loan
facility.
 
     On October 31, 1996, SpeedFam U.K., the Company's wholly-owned subsidiary
in the United Kingdom, entered into a L950,000 ($1.5 million) Multi-Currency
Revolving Line of Credit. The credit facility was provided to support the
operating and working capital needs of the Company's British subsidiary. At
August 31, 1997, no amounts were outstanding on this loan.
 
     The Company currently anticipates capital expenditures of approximately
$30.5 million for fiscal 1998. The Company believes that cash generated from
operations, together with the proceeds from this offering and the revolving loan
facilities will be sufficient to meet the Company's capital requirements during
at least the next 12 months.
 
RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS
 
     Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share" is effective for financial statements issued for periods ending after
December 15, 1997. SFAS No. 128 replaces Accounting Principles Board Opinion
("APB") No. 15 and simplifies the computation of earnings per share ("EPS") by
replacing the presentation of primary EPS with a presentation of basic EPS.
Basic EPS includes no dilution and is computed by dividing income available to
common stockholders by the weighted-average number of common shares outstanding
for the period. Diluted EPS reflects the potential dilution from securities that
could share in the earnings of the Company, similar to fully diluted EPS under
APB No. 15. The Statement requires dual presentation of basic and diluted EPS by
entities with complex capital structures. The Company will adopt SFAS No. 128
for the financial statements for the year ended May 31, 1998.
 
     SFAS No. 130, "Reporting Comprehensive Income" is effective for fiscal
years beginning after December 15, 1997. SFAS No. 130 establishes standards for
the reporting and display of comprehensive
 
                                       25
<PAGE>   27
 
income and its components (revenues, expenses, gains and losses) in a full set
of general-purpose financial statements. The Statement requires that all items
that are required to be recognized under accounting standards as components of
comprehensive income be reported in a financial statement that is displayed with
the same prominence as other financial statements. The Company is evaluating the
Statement's provisions to conclude how it will present comprehensive income in
its financial statements, and has not yet determined the amounts to be
disclosed. The Company will adopt SFAS No. 130 effective June 1, 1998.
 
     SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information" is effective for financial statements for periods beginning after
December 15, 1997. SFAS No. 131 establishes standards for the way that public
business enterprises report financial and descriptive information about
reportable operating segments in annual financial statements and interim
financial reports issued to stockholders. SFAS No. 131 supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise," but retains the
requirement to report information about major customers. The Company is
evaluating the new Statement's provisions to determine the additional
disclosures required in its financial statements, if any. The Company will adopt
SFAS No. 131 effective June 1, 1998.

     SpeedFam designs, develops, manufactures, markets and services chemical
mechanical planarization, or "CMP," systems used in the fabrication of
semiconductor devices and other high throughput precision surface processing
systems used in the fabrication of thin film memory disk media, semiconductor
wafers and general industrial components. In addition, the Company markets and
distributes slurries and parts and expendables used in its customers'
manufacturing processes. The Company's processing systems include polishing,
grinding, lapping and pre-deposition cleaning equipment. The process steps
performed by the Company's equipment are an integral part of and occur
repeatedly throughout the fabrication cycles of advanced semiconductors, thin
film memory disk media and semiconductor wafers. The Company has been utilizing
innovative designs, formulas and process technologies to address its customers'
precision surface processing needs since 1959. The Company believes that the
processing expertise it has developed in over 35 years enables it to provide
precision surface processing solutions to leading-edge electronics manufacturers
who require increasingly smaller device geometries and tighter process
tolerances. Major customers of the Company include AMD, Akashic,
Hewlett-Packard, IBM, Komag, MEMC, Mitsubishi Siltec, Motorola, Rockwell
International, Seagate, Siemens and Wacker Siltronic.
 
INDUSTRY BACKGROUND
 
     The semiconductor and memory disk industries have experienced rapid growth
as a result of the personal computer, telecommunications and networking markets
and the emergence of consumer-oriented semiconductor applications in products
such as automobiles, electronic games and other consumer electronics. The
computer markets are characterized by the emergence of new operating systems
that require higher processor performance, more memory and increased disk
storage to run effectively. In both the computing and consumer-oriented markets,
end users demand greater system performance, along with product features such as
small size, portability, long battery life and cool operation.
 
     The heightened requirements of end users for increased system performance,
processing capacity and product features are requiring semiconductor and thin
film memory disk manufacturers to rapidly adopt new technologies. Thus,
semiconductor device manufacturers are producing devices with smaller geometries
and multi-level metal processes. Similarly, thin film memory disk media
manufacturers are continually increasing the density of disk media by increasing
coercivity (magnetic density) and reducing head flying heights in order to
satisfy end user demand for greater storage capacity.
 
     In order to meet these evolving specifications, both semiconductor and thin
film memory disk manufacturers must tighten tolerances and improve certain
surface characteristics. At present, some complex semiconductor devices have
line geometries and feature sizes of less than 0.35 micron, and devices with
geometries of 0.18 micron or less are under development. In the last decade,
coercivity requirements have increased from approximately 800 oersteds to 2,200
oersteds or more and flying height requirements have decreased to less than 0.5
microinch. Such dramatic increases in coercivity and reductions in flying
heights require improved thin film memory disk media surface quality. These
tightened tolerances necessitate improvements in the semiconductor and thin film
memory disk media manufacturing processes in order to increase planarity
(flatness) and provide a number of new surface characteristics.
 
     Polishing is a process used to change the characteristics of the surface of
a semiconductor wafer or thin film memory disk. Polishing is a complex science,
often involving multiple steps, each at a specified set of process parameters
such as polishing speed, pressure, time, and temperature, as well as slurry pH
and particle size, hardness and shape. Polishing improves the flatness
(planarity), smoothness and optical properties of a surface. A typical flat
polishing system consists of a moving platen that is covered with a polishing
pad, in combination with a polishing liquid (or slurry) containing abrasive
particles that impinge on the surface, thereby creating the desired surface
qualities. This liquid slurry can be chemically active such that the surface of
the component being polished is chemically modified, thus accelerating and
improving the polishing process. The combination of chemical action from the
acidic or alkaline slurry and mechanical action from the abrasive slurry is used
to process silicon wafers, thin film memory disk media and advanced
semiconductor devices.
 
                                       27
<PAGE>   29
 
EMERGENCE OF CMP PROCESS
 
     The objective of CMP in the manufacture of semiconductor devices is to
reestablish a flat or planar surface that has been degraded by prior deposition
steps to a point where it is not possible or feasible to deposit additional
levels without first restoring the surface to a planar condition. For example,
after a microprocessor device has had several levels of metal deposited, the
surface may have become so irregular that the optics of the photolithography
equipment may be unable to maintain proper focus on all areas of the wafer
surface. During the CMP process, the higher points of the dielectric or metal
layer are removed, resulting in a flatter and more even surface. This provides a
level foundation on which to deposit the next level of circuitry. CMP allows
semiconductor manufacturers to make denser, smaller, faster and more reliable
devices by enabling them to effectively stack many levels of interconnection.
 
     End user performance demands are requiring semiconductor manufacturers to
produce increasingly sophisticated logic and memory devices containing multiple
metal layers. Because of the depth of focus limitations of existing
photolithography equipment, global planarization becomes particularly important
for devices with design geometries of 0.35 micron or less and three or more
metal levels. The Company believes that the CMP process is currently the most
effective method to provide this global planarization. According to Dataquest
Incorporated, the CMP equipment market was estimated at $316 million in 1996 and
it currently projects the market to be approximately $1.2 billion in the year
2001.
 
CMP MARKET REQUIREMENTS
 
     The Company believes that manufacturers of semiconductor devices consider
many factors in evaluating a CMP system, including the following:
 
     Cost of Ownership.  Cost of ownership refers to the total cost to a
manufacturer of processing a wafer assuming a given set of process parameters.
Key factors that determine cost of ownership include capital equipment and
consumables costs, throughput, yield, reliability and amount of clean room space
occupied by the CMP system, or "footprint."
 
     Throughput.  Throughput is determined by measuring the number of wafers
processed per unit of time given a certain set of process conditions, such as
the amount of material requiring removal.
 
     Process Flexibility, Performance and Reliability.  Flexibility is
determined by the ability of a CMP system to address the evolving process and
application needs of semiconductor device manufacturers. Specifically, the
Company believes that semiconductor device manufacturers want a common,
standardized CMP system capable of processing various film types, including
metal, oxide and other materials. Performance is primarily characterized by the
ability to repeatedly create precise, uniform film layers while achieving rapid
removal rates. Reliability of a CMP system is analyzed through measures such as
"mean time between failures" (MTBF), "mean wafers between failures" (MWBF) and
"mean wafers between interruptions" (MWBI).
 
     Support and Other Capabilities of the CMP Supplier.  Semiconductor device
manufacturers typically review the CMP supplier's support and other
capabilities, including the supplier's management systems, support locations,
training capabilities, research and development capabilities, technology roadmap
and process development activities.
 
     Emerging Requirements.  Emerging requirements of semiconductor device
manufacturers include CMP systems with integrated post-CMP cleaning capability
that enable reduced handling of wet product wafers and more efficient
utilization of clean room space. Device manufacturers are also seeking systems
that incorporate in situ end-point detection capability to measure the remaining
thickness of oxide or metal layers in order to determine precisely when the
desired film thickness has been achieved during the CMP process.
 
     CMP systems typically utilize polishing heads that hold wafers during the
planarization process. Historically, many CMP systems employed either one or two
head system architectures that permitted the processing of only one or two
wafers at a time. The Company believes that the architecture of these one or two
head systems limits their ability to adequately address the CMP objectives of
semiconductor device
 
                                       28
<PAGE>   30
 
manufacturers, particularly with respect to cost of ownership and throughput.
The Company believes that multiple head CMP systems have inherent advantages
over one and two head CMP systems. The Company was one of the earliest
manufacturers to develop and ship commercial quantities of a multiple head CMP
system. A number of CMP equipment manufacturers have introduced multiple head
systems and the Company expects other such systems to be introduced in the
future.
 
THE SPEEDFAM CMP SOLUTION
 
     The Company has leveraged its 35 years of experience in precision surface
processing, polishing, wet processing and high-throughput production equipment
to develop its CMP system. The Company began developing the CMP-V in 1990 and
initiated commercial shipments during 1994. The Company introduced its "second
generation" CMP system, the Auriga, in 1996 and shipments of that system began
in the second quarter of fiscal 1997. The Company recently introduced the
Auriga-C, which integrates technology from the Company's Capella, its post-CMP
cleaning system, thereby providing a dry-in/dry-out system. The Company has also
recently introduced the Altair, an in situ end-point detection system.
Deliveries of the Auriga-C for revenue are expected to begin in the second
quarter of fiscal 1998. Each of the Company's CMP systems utilize a five head,
two polishing table architecture that is designed to address the objectives of
semiconductor device manufacturers in the following respects:
 
     Cost of Ownership.  The Auriga is designed to provide a favorable
combination of capital equipment and consumables costs, throughput, yield and
space utilization. For example, the Company's CMP systems' use of a large
polishing table to process five wafers simultaneously results in enhanced
throughput, efficient consumables usage, and effective clean room space
utilization.
 
     Throughput.  The Auriga is designed to optimize throughput in a number of
ways. First, the system processes five wafers simultaneously and uses batch
load/unload in order to reduce handling time between process runs. The two table
design of the system allows it to directly perform a secondary polishing step,
important for most metal CMP applications, without having to unload and load a
wafer onto a separate carrier. In addition, the utilization of a relatively
large polishing wheel is designed to enable the Auriga to achieve relatively
high removal rates and throughput while maintaining process stability and
control. Material removal rate is generally proportional to the relative
velocity between the surface of the polishing pad and the semiconductor wafer.
The Company believes its larger polishing wheel provides higher relative
velocities even while the wheel is turning at a relatively low rotational speed.
The Auriga system incorporates certain modifications from the CMP-V in the
control and automation system in order to decrease the time interval between
processes, thereby increasing the number of wafers processed.
 
     Process Flexibility, Performance and Reliability.  The Auriga supports a
range of applications, including oxide, metal and emerging CMP applications.
Specifically, the system is designed to provide the uniformity needed for oxide
applications, while providing efficient support for two-step metal applications
through its two table architecture. The Company believes that this ability to
support both oxide and metal applications in a single system provides a solution
to device manufacturers seeking to standardize on a common CMP system throughout
their fabrication facility. The Company believes that the Auriga achieves the
precision and uniformity of film layers typically required in CMP applications
for advanced process technologies, including both oxide and metal applications.
The Company seeks to continually improve the performance of the Auriga system
and, from time to time, engages in joint development projects with customers
from the semiconductor industry as a means to enhance the system's reliability
and process performance.
 
     Support and Other Capabilities of the CMP Supplier.  The Company believes
that its United States and European support capabilities, in combination with
the support capabilities of the Far East Joint Venture, provide a network that
is able to support the worldwide CMP operations of semiconductor device
manufacturers. The Company is committed to significant investment in research
and development in order to provide customers with a CMP product and technology
migration strategy consistent with the SIA (Semiconductor Industry Association)
technology roadmap.
 
     Emerging Requirements.  The Company's recently introduced Auriga-C system
has been designed to address the market's demand for an integrated post-CMP
cleaning capability. The Auriga-C maintains the
 
                                       29
<PAGE>   31
 
high throughput design of the original Auriga platform while integrating the
Company's post-CMP cleaning technology to provide a dry-in/dry-out system in
substantially the same system footprint as the Auriga. The Company has also
recently introduced an in situ end-point detection system, the Altair, which is
designed to measure precisely the film thickness of oxide or metal layers.
 
SPEEDFAM STRATEGY
 
     The Company's goal is to establish and maintain market leadership in
systems which provide high throughput precision surface processing of advanced
semiconductors, thin film disk media and other high value-added products. Key
elements of the Company's strategy include:
 
     - Maintain a leading position in the CMP market.  The Company seeks to
     leverage its expertise in precision surface processing systems to maintain
     a leading position in the CMP market. The Company's multiple head, two
     polishing table CMP system is designed to provide high throughput, low cost
     of ownership and attractive levels of process flexibility. The Company
     seeks to capitalize on the experience gained by being one of the earliest
     manufacturers to develop and ship commercial quantities of a multiple head
     CMP system. The Company has recently introduced the Auriga-C, which
     integrates technology from the Company's Capella, its post-CMP cleaning
     system, thereby providing a dry-in/dry-out system. The Company has also
     recently introduced the Altair, an in situ end-point detection system.
     Deliveries of the Auriga-C for revenue are expected to begin in the second
     quarter of fiscal 1998.
 
     - Maintain a leading position in the sale of precision surfacing processing
     systems to the thin film memory disk media and silicon wafer
     industries.  The Company intends to maintain a leading position in the thin
     film memory disk media and silicon wafer industries by continuing to foster
     strong relationships with its customers, participating in cooperative
     development programs with them and continuing to provide high-quality
     systems and solutions at competitive prices to meet evolving industry
     requirements.
 
     - Capitalize on the Company's core competence in precision surface
     processing and leverage existing customer relationships.  The Company
     intends to capitalize on its surface processing expertise and its existing
     customer relationships to address new market applications, particularly
     within the semiconductor industry, and to develop new products.
 
     - Provide a "total solution."  The Company seeks to provide a complete
     solution to its customers' precision tolerance and surface processing
     needs, including process expertise, training, cooperative development,
     slurries and expendables, along with equipment. The Company focuses on each
     market application by organizing marketing, sales, service and support
     functions into separate market-oriented business units to provide
     responsiveness and capability specific to each market.
 
     - Capitalize on the Far East Joint Venture.  The Far East Joint Venture,
     which has been operating for approximately 25 years, designs, manufactures,
     markets and services high throughput precision surface processing systems
     in the Far East. The Company intends to continue to capitalize on the
     opportunities and benefits provided by the Far East Joint Venture. The Far
     East is a major market for equipment required by the semiconductor and thin
     film memory disk media industries. In addition, because the Far East high
     technology markets may adopt certain new technologies prior to the U.S.
     markets, the Company may be able to take advantage of the expertise gained
     by the Far East Joint Venture prior to the time those new technologies are
     introduced into the U.S. markets. The Company believes that the Far East
     Joint Venture's long-established presence in the Far East provides the
     Company with a significant competitive advantage.
 
JOINT VENTURES
 
     Since 1971, the Company has owned a 50% interest in the Far East Joint
Venture. The remaining 50% is owned by Obara Corporation, a privately-owned
Japanese company that supplies products to the automotive industry. Generally,
the Far East Joint Venture designs, produces and markets in the Far East
equipment similar to that produced by the Company in the U.S. Prior to 1971, the
Company marketed its products in
 
                                       30
<PAGE>   32
 
Japan through Japanese trading companies; however, the Company believed that the
most effective method to further penetrate the Japanese market was with a
Japanese partner. See "Joint Venture Arrangements -- Far East Joint Venture." In
1984, the Company established the Fujimi Joint Venture with Fujimi Incorporated,
a publicly-traded Japanese manufacturer of slurries. The Fujimi Joint Venture
sells slurries manufactured by Fujimi Incorporated, primarily to silicon wafer
manufacturers and general industrial manufacturers in North America. See
"-- Manufacturing and Suppliers" and "Joint Venture Arrangements -- Fujimi Joint
Venture."
 
PRODUCTS
 
     SpeedFam's products include polishing, grinding and lapping equipment;
pre-deposition cleaning machines; other high precision surface processing
systems; and certain other products used in its customers' manufacturing
process, including slurries. During fiscal years 1995, 1996 and 1997, 54.5%,
78.5% and 84.8%, respectively, of the Company's total revenue (including
commissions) was attributable to the sale of capital equipment, parts and
expendables and 45.5%, 21.5% and 15.2%, respectively, of the Company's total
revenue was attributable to sales of slurries.
 
  Applications
 
     The areas indicated in the table below set forth the general categories of
processes and certain individual applications performed by products marketed by
SpeedFam:
 
                     Speedfam Process & Applications Chart
 
     SpeedFam offers equipment that performs specialized surface processing,
such as polishing, lapping, free abrasive machining and grinding. The Company's
polishing systems generally employ a flat rotating table covered with a
polishing pad, one or more carriers to hold the parts being processed and
slurry. Processes similar to polishing include lapping (a process where no
polishing pad is used and the workpiece is pressed into the slurry which is
applied to a cast-iron lapping wheel) and free abrasive machining ("FAM", a
process similar to lapping except that instead of a cast-iron wheel, a high
alloy hardened steel wheel is used). Lapping and free abrasive machining result
in higher removal rates than polishing but produce rougher surface finishes.
Grinding is a conventional machining process in which abrasive particles are
contained within a fixed medium (grinding stones), rather than a liquid.
Grinding produces significantly higher removal rates than lapping but produces a
coarser surface finish. Dimensional tolerance, surface finish, quantity of
material to be removed along with production rates required and cost of
operation are the primary variables considered in the determination of the best
process for a specific application. Polishing and other surface treatment
processes are typically followed by a cleaning process. Thin film memory disk
cleaning systems offered by SpeedFam incorporate ultrasonics, PVA (polyvinyl
alcohol) brush scrubbing, rinsing and drying in a Class 1 cleanroom-compatible
system.

  Equipment
 
     Semiconductor Chemical Mechanical Polishing (CMP).  The Company currently
offers the Auriga, a five head, two polishing table CMP system capable of
processing 65-90 wafers per hour based on commonly used polishing cycles. The
Auriga system, which began shipping commercially in November 1996, incorporates
certain modifications from the Company's original system for chemical mechanical
planarization of semiconductor devices, the CMP-V, in the control and automation
system in order to decrease the time interval between processes, thereby
increasing the number of wafers processed. The Company's CMP process is
currently characterized and in production for oxide and metal (tungsten)
applications. The system incorporates full cassette-to-cassette automation.
Robotics remove the wafers from the cassette and place them into the buffer
tray. The wafers are then staged for batch pickup by the polishing heads. Once
secured by the polishing heads, the wafers are moved onto the primary polishing
pad and the process is initiated. The polishing table, covered with a flat
polishing pad, rotates at a variable speed throughout the polishing cycle. Upon
completion of the initial polish, the wafers are transported either to a rinsing
station or to a second polishing table for an additional polishing or buffing
step. The wafers are then rinsed and placed into the output buffer tray,
scrubbed on both sides with a wet PVA sponge and placed wet into the output
cassettes. The system is self-enclosed, and has its own air filtration and air
flow management system. Each of the Company's CMP systems offers compatibility
with all commonly used slurry chemistries and are produced solely by the
Company. Depending on specifications, the selling price of the Auriga in the
U.S. ranges from $1.9 million to $2.3 million.

     In addition, the Company has recently introduced the Auriga-C, which
integrates technology from the Company's Capella, its post-CMP cleaning system,
thereby providing a dry-in/dry-out system. The design of the Auriga-C is based
upon the replacement of the automation module on the Auriga with a new
automation module which incorporates the Capella cleaning technology. The
Company has also recently introduced the Altair, an in situ end-point detection
system. The Company has had limited experience with the production of the
Auriga-C and may encounter difficulties in its production. Further, the Auriga-C
has only recently begun testing in the Company's laboratories and has not yet
been shipped to customers for evaluation. Deliveries of the Auriga-C for revenue
are expected to begin in the second quarter of fiscal 1998. As with any new
product introduction, there are risks that final customer acceptance may take
longer than scheduled.

     The MD line of cleaning systems are used to clean the substrate at various
stages of the manufacturing process, including the critical cleaning immediately
prior to the deposition of the magnetic layers. Cleaning systems distributed by
the Company are produced solely by the Far East Joint Venture. Typical U.S.
selling prices for the MD line of cleaning systems range from $200,000 to
$900,000.
 
     Semiconductor Wafers.  The Company supplies chemical mechanical polishing,
double-sided lapping and, more recently, edge polishing systems to the
semiconductor substrates market.
 
     The following chart describes the major steps in the typical silicon
semiconductor wafer manufacturing process:
 
           [SILICON SEMICONDUCTOR WAFER MANUFACTURING PROCESS CHART]
 
     The Company's DSM line of double-sided lapping systems is available in
various sizes and is used to create the initial flatness and thickness of the
silicon wafer after it is sliced from an ingot. The lapping process also removes
saw marks remaining after slicing and provides a surface finish suitable for
subsequent polishing processes. DSM double-sided polishers for silicon wafer
polishing are also available. Typical U.S. selling prices for the DSM line range
from $300,000 to $1.5 million.
 
     The SPAW line utilizes a chemical mechanical polishing process to remove
the shallow damage layer remaining from previous process steps and to attain the
specified flatness and surface finish. A 50-inch model is manufactured by the
Company in the U.S. and a 59-inch model is manufactured by the Far East Joint
Venture. The 50-inch model typically sells in the U.S. for between approximately
$250,000 and $450,000. The 59-inch model typically sells in the U.S. for between
$700,000 and $1 million, but is also available as a fully automated line
integrating four 59-inch models, which can sell for up to $4.9 million.
 
     The Company began distributing the EP line of edge polishing systems during
fiscal 1995. Edge polishing has emerged as a new technology that is being
incorporated into high volume silicon wafer manufacturing. This technology was
developed and introduced for the purpose of making the wafer's edge easier to
clean, thereby increasing semiconductor device manufacturing yields. The Far
East Joint Venture produces the EP line that is marketed and distributed by the
Company. Typical U.S. selling prices for the EP line range from $400,000 to
$800,000.

     General Industrial.  The Company offers a broad line of lapping, grinding
and polishing systems for the general industrial market. The line includes
approximately 35 models of single-side processing machines, double-side
processing machines, in-line grinding systems and optics polishing machines. The
product offering is available in a wide range of sizes from a 12 inch plate
diameter up to a 150 inch plate diameter. Each system typically consists of a
specialized machining plate, a rotating spindle, a means to fix and apply
pressure to the workpieces, an abrasive distribution system and a control
system. U.S. selling prices of these systems typically range from $20,000 to
$700,000.
 
  Parts and Expendables
 
     The Company markets a broad line of parts and expendables. These products
include general spare parts, bearings, grinding stones, lapping plates,
workpiece carriers, seals, retaining rings, workholders and polishing pads.
These products are typically obtained from outside vendors and are generally
manufactured to the Company's specifications. The Company maintains spare parts
inventories at six U.S. locations and two European locations. The Company
believes that its ability to quickly supply parts and expendables is an
important factor in its ability to provide customers with a total solution.
 
  Slurries
 
     The Company offers a broad line of slurry and slurry components (including
vehicles and abrasives) used in surface treatment processes as part of a total
process solution. Polishing slurry consists of abrasive particles contained in a
liquid vehicle that may contain a suspension agent and may be chemically active.
The slurries marketed by the Company are used by manufacturers of thin film
memory disk media, semiconductor wafers and other products as part of their
polishing processes.
 
     Substantially all of the slurries sold by the Company are manufactured by
Fujimi Incorporated. Typical U.S. selling prices of slurry offered by the
Company range from $1,000 to $1,500 per 55-gallon drum.
 
     The Company has entered into the Fujimi Joint Venture with Fujimi
Incorporated to sell certain products in North and South American markets,
including slurry and slurry components. The Company distributes thin film memory
disk polishing slurry and related products supplied by Fujimi Incorporated,
while the Fujimi Joint Venture distributes other products supplied by Fujimi
Incorporated. To date, no material sales of products have been made to South
American markets by the Fujimi Joint Venture. See "Joint Venture
Arrangements -- Fujimi Joint Venture."
 
     The slurry for thin film memory disk media polishing applications is
available in different varieties to address the varying needs of each specific
process. Some formulations allow higher stock removal rates and others emphasize
surface finish results. There are also a variety of slurry formulations
available for silicon wafer processing. Slurry is an essential process component
in chemical mechanical polishing. The chemical action of this process is
implemented by designing the slurry to be chemically active with the surface to
be polished, typically by adjusting the pH of the slurry vehicle. The mechanical
portion of the process is accomplished by abrasive particles in the slurry.
 
     The Company believes that meeting the evolving slurry requirements of each
customer is vital to providing a total process solution. The Company intends to
continue to maintain an emphasis on slurry distribution and to work closely with
Fujimi Incorporated in developing, designing and formulating customized slurries
that address specific customer needs.
 
CUSTOMERS
 
     The Company sells its products to leading manufacturers of semiconductor
devices, thin film memory disks, semiconductor wafers and for various industrial
applications. Certain of the Company's top customers in fiscal 1995, 1996 and
1997 in the semiconductor device, thin film memory disk media, semiconductor
wafer, and general industrial application markets are listed below.

     The Company's ten largest customers accounted for 66.9%, 64.4% and 59.8% of
the Company's total revenue in fiscal years 1995, 1996 and 1997, respectively.
One customer, Komag, accounted for 20.6%, 17.8% and 10.3% of the Company's total
revenue in fiscal years 1995, 1996 and 1997, respectively. Although Komag has
represented a significant portion of the Company's sales of polishing machines
to the thin film memory disk market in the past, it is not anticipated that
Komag will represent as significant a portion of such sales in the future. AMD
accounted for 12.8% of the Company's total revenue for 1997. In addition, during
fiscal 1995, Akashic accounted for 10.9% of the Company's total revenue.
 
SALES AND MARKETING
 
     The Company markets and sells its products in North America through a
combination of direct sales personnel and distributors. The Company sells
directly to the semiconductor and thin film memory disk media industries and
uses a network of 14 regional distributors for its general industrial product
lines. In its European operations, the Company uses direct sales personnel and a
small number of distributors. The Company markets and sells its products in the
Far East through the sales and marketing arm of the Far East Joint Venture.
 
     The Company's sales strategy emphasizes direct interaction with customers,
particularly in the semiconductor and memory disk industries, where ongoing
customer support and service are critical. The Company's direct sales force is
divided into focused units for each of the semiconductor devices, thin film
memory disk media and semiconductor wafer industries.
 
     At May 31, 1997, the U.S. direct sales organization had a total of 23 sales
personnel. The Company's main sales offices are in Chandler, Arizona, Austin,
Texas and Elk Grove Village, Illinois. The Company also had an aggregate of nine
direct sales personnel in the SpeedFam U.K. and SpeedFam Germany offices. To
enhance its sales capabilities, the Company maintains process development and
demonstration laboratories in the U.S. and Europe. Sales and marketing
activities in the Far East are conducted by the Far East Joint Venture. See
"Joint Venture Arrangements -- Far East Joint Venture."
 
     The Company's marketing strategy includes involvement with SEMATECH, Inc.,
a consortium of major semiconductor manufacturers and equipment suppliers,
attendance at Semicon, Diskcon, IMTS and other trade shows worldwide and the
sponsorship of technical conferences, which include the presentation of
technical papers written by customers, university scientists and the Company's
own senior technologists. The Company believes these initiatives serve to
promote acceptance of the Company's products and process technologies in the
semiconductor, thin film memory disk and other industries.

CUSTOMER SERVICE AND SUPPORT
 
     The Company believes that providing highly responsive service is an
essential factor in providing a total solution to its customers. In order to
provide customers with experienced service and support personnel, the Company
has structured its service operations into distinct service units responsible
for each of the semiconductor device, thin film memory disk media, semiconductor
wafer and general industrial products industries. Elements of the Company's
customer service and support program include system installation and process
certification, process support, machine repair, providing spare parts
inventories, internal training programs, external customer training,
documentation and formation of customer user groups. At May 31, 1997, the
Company had 137 service employees in the U.S. and Europe. For large users of the
Company's systems, the Company often creates a customized service arrangement
designed to meet the specific requirements of the customer.
 
     The Company generally provides a one year warranty on all equipment it
sells. Field service personnel provide warranty service, post-warranty service,
and equipment installations. Field service engineers are located in various
locations throughout the world, including dedicated site-specific engineers in
place at certain customer locations pursuant to contractual arrangements. The
Company also provides service and maintenance training as well as process
application training for its customers' personnel. The Company maintains an
extensive inventory of spare parts at its primary locations and at its satellite
service sites. This provides the Company the ability to provide same day or
overnight delivery for many parts.
 
BACKLOG
 
     Backlog of orders for capital equipment, parts, expendables and slurries
increased to approximately $68.3 million at August 31, 1997, from approximately
$41.4 million at August 31, 1996. Approximately $58.3 million, or 85.5% of the
total backlog at August 31, 1997, is comprised of orders for capital equipment.
The Company's backlog does not include orders for capital equipment or other
products manufactured by the Far East Joint Venture and distributed by the
Company in the U.S. and Europe for which the Company receives commissions. The
time between the placing of orders and shipment of parts, expendables and
slurries is significantly less than for capital equipment and as a result, the
Company's backlog consists primarily of orders for capital equipment. The
Company includes in its backlog only those customer orders for which it has
accepted signed purchase orders with assigned delivery dates within 12 months.
Orders generally carry a stipulation that customers may incur a penalty in the
event of cancellation. However, there can be no assurance that orders will not
be cancelled by customers or that the Company will obtain a meaningful penalty
payment. As a result of systems and equipment ordered and shipped in the same
quarter, possible changes in delivery schedules, occasional cancellation of
orders and delays in product shipments, the Company's backlog at any particular
date may not be indicative of actual sales for any succeeding period.
 
RESEARCH, DEVELOPMENT AND ENGINEERING
 
     The markets in which the Company competes are characterized by evolving
industry standards and frequent improvements in products and service. To compete
effectively in its markets, the Company must continually improve its products
and its process technologies and develop new technologies and products that
compete effectively on the basis of price and performance and that adequately
address current and future customer requirements. The Company's research,
development and engineering expenditures during fiscal 1995, 1996 and 1997, were
approximately $2.7 million, $11.5 million and $19.8 million, respectively.
 
     At May 31, 1997, the Company had an engineering staff of 55 employees and a
research and development staff of 62 employees. Because of the complex and
highly specialized design, testing and manufacturing requirements of the
Company, these employees must be experienced in a wide range of engineering
disciplines. The Company's philosophy is to maintain strong technical expertise
in each of its core competencies and to utilize consulting engineers for
non-critical portions of product development projects. The Company believes that
this approach provides flexibility and allows the Company to shorten time to
market for new products.
 
                                       37
<PAGE>   39
 
  Product Development
 
     The Company began shipments of the Auriga, an enhanced version of the
CMP-V, its original system, in the second quarter of fiscal 1997. The Company
intends to periodically develop and introduce enhanced versions of its CMP
system. The Company has also recently introduced the Capella, a post-CMP
cleaning system. In addition, the Company has also recently introduced the
Auriga-C, which integrates technology from this cleaning system to provide a
dry-in/dry-out system. The Company is also developing additional products and
product enhancements for the thin film memory disk and silicon wafer markets.
 
     Typically, the Company works with either a "user-group" of current and
potential customers or a key customer to act as technical advisors during the
conceptualization of a new product. The Company's CMP system was developed in a
similar manner and its development was assisted through technical collaboration
with and sponsorship by SEMATECH, Inc. and several SEMATECH, Inc. member
companies that are leaders in the use of CMP technology. From time to time, the
Company also engages in formal, funded joint development projects with customers
from the semiconductor and thin film memory disk industries as a means to
enhance its product development efforts.
 
  Process Development
 
     In addition to product development, the Company continually seeks to
enhance existing processes. The Company maintains process development
laboratories in both the U.S. and Europe that are staffed with process
engineers. The Company's process engineers frequently work directly with
customers' engineers, often working within the customers' facilities. The
Company is continuing to develop new processing capability in the CMP area for
improved planarity, higher removal rates and emerging film applications, such as
copper. The Company has also developed and recently introduced an end-point
detection system, the Altair, for the purpose of measuring the film thickness of
oxide and metal layers of advanced semiconductor devices. The Company is
currently in the preliminary stage of its development program for 300mm CMP
products. In the thin film memory disk area, the Company also continues to
pursue the development of automated machines and enhanced processes, as well as
machine refinements providing improved process performance.
 
MANUFACTURING AND SUPPLIERS
 
     The Company assembles its equipment and systems from components and
fabricated parts manufactured and supplied by others, including stainless steel
plates and gears, frames and weldments, power supplies, process controllers,
robots and polishing heads. Certain of the items manufactured by others are made
to the Company's specifications. All final assembly and system tests are
performed within the Company's manufacturing/assembly facilities. Quality
control is maintained through incoming inspection of components, in-process
inspection during equipment assembly and final inspection and operation of all
manufactured equipment prior to shipment. Substantially all of the Company's
non-CMP manufacturing is located in its Illinois facilities. The Company's CMP
system development and manufacturing are located at the Company's headquarters
in Chandler, Arizona.
 
     Certain of the components and sub-assemblies included in the Company's
products are obtained from a single supplier or limited group of suppliers. The
disruption or termination of these sources could have a material adverse effect
on the Company's operations. The Company is dependent upon Fujimi Incorporated,
a Japanese company, as the sole supplier of substantially all of the slurries
sold by the Company, consisting primarily of thin film memory disk polishing
slurry. Approximately 43.4%, 19.7% and 14.4% of the Company's total revenue in
fiscal 1995, 1996 and 1997, respectively, was derived from the sale of slurries
and other products supplied by Fujimi Incorporated. Accordingly, any disruption
in the supply provided by Fujimi Incorporated or in the overall relationship
between the Company and Fujimi Incorporated would have a material adverse effect
upon the Company. The Company has the exclusive right to distribute Fujimi
Incorporated thin film memory disk polishing slurry in North America until
October 1, 1999. See "Joint Venture Arrangements -- Fujimi Joint Venture."

COMPETITION
 
     The Company competes in several distinct markets. These markets include the
semiconductor device equipment market, the thin film memory disk media equipment
market, the semiconductor wafer equipment market, the general industrial
applications market, and the related parts and expendables market. In all
markets, the Company competes on the basis of technology, overall cost of
ownership, product quality, price, availability, size of installed base, breadth
of product line and customer service and support.
 
     The Company faces substantial competition from both established competitors
and from potential new entrants, some of which have substantially greater
financial, engineering, manufacturing and marketing resources than the Company.
In the semiconductor device equipment market, the Company faces significant
competition from current competitors and any others that may enter this market
in the future. IPEC currently has the largest installed base of CMP equipment.
Other companies in this market are in various stages of development of CMP
machines. Specifically, Applied Materials, a large semiconductor capital
equipment supplier with significant resources, has introduced a multiple head
CMP machine and IPEC has begun shipments of multiple head CMP systems. Ebara, a
Japanese capital equipment manufacturer, has begun shipments of a multiple head,
dry-in/dry-out system, primarily in the Far East. In addition, certain of the
Company's competitors have longer-standing relationships than the Company with
particular customers, including semiconductor device manufacturers. These
longer-standing relationships may make it more difficult for the Company to sell
its CMP system to such device manufacturers. Consolidation among CMP equipment
suppliers or the acquisition of CMP equipment suppliers by large, established
suppliers of non-CMP capital equipment to semiconductor device manufacturers or
others could materially adversely affect the Company's ability to compete and
would have a material adverse effect on the Company's results of operations. In
the thin film memory disk and semiconductor wafer equipment markets, the Company
competes with a relatively few significant competitors.
 
     Competition in the general industrial products markets is fragmented; no
one competitor currently holds a dominant position. The Company faces
significant competitive pressure in the sale of slurries, particularly with
regard to pricing, resulting in decreased margins for certain products of the
Company in recent periods. In the thin film memory disk slurry market, the
Company competes primarily with Praxair, a large chemical company that
manufactures and sells its own products. In addition, the loss of the Company's
distribution rights to slurry and other products supplied by Fujimi Incorporated
would have a material adverse effect on the Company.
 
INTELLECTUAL PROPERTY
 
     The Company currently holds numerous United States patents and additional
foreign patents in Japan and several Asian and European countries and has
numerous United States and foreign patent applications pending. The Company has
recently become increasingly aggressive with respect to patent applications,
especially in the CMP area. In addition, the Company believes that such factors
as continued innovation, technical expertise and know-how of its personnel and
other factors are also important. The Company owns eight U.S. trademark
registrations. The Company also owns numerous foreign trademarks.
 
     There can be no assurance that the Company's pending patent applications
will be allowed or that the issued or pending patents will not be challenged or
circumvented by competitors. There can be no assurance that any of these rights
held by the Company will not be challenged, invalidated or circumvented, or that
such rights will provide competitive advantages to the Company.
 
     There are no pending lawsuits against the Company regarding infringement of
any existing patents or other intellectual property rights or any unresolved
claims by third parties that the Company is infringing intellectual property
rights of such third parties. There can be no assurance that infringement claims
will not be asserted by third parties in the future. There also can be no
assurance in the event of such claims of infringement that the Company will be
able to obtain licenses on reasonable terms, if at all. The Company's
involvement in any patent dispute or other intellectual property dispute or
action could have a material adverse effect on the Company's business. Adverse
determinations in any litigation relating to intellectual property could
possibly subject the Company to significant liabilities to third parties,
require the Company to seek
 
                                       39
<PAGE>   41
 
licenses from third parties and prevent the Company from manufacturing and
selling one or more of its products. Any of these events could have a material
adverse effect on the Company.
 
     SPEEDFAM, FAM, SPITFIRE and the SPEEDFAM logo are registered trademarks of
the Company.
 
PROPERTY
 
     The Company currently owns or leases buildings containing a total of
approximately 258,000 square feet of space in the U.S. and Europe, including
approximately 133,000 square feet of factory/assembly area and approximately
125,000 square feet of corporate office space. The Company's U.S. operations
(the SpeedFam International, Inc. headquarters and the SpeedFam U.S. subsidiary)
account for approximately 247,000 square feet of the total, of which
approximately 176,000 square feet is owned (including the recently completed
135,000 square foot corporate headquarters and manufacturing facility in
Chandler, Arizona). The balance of approximately 71,000 square feet is leased.
The Company maintains locations in the United States in Chandler, Arizona, Des
Plaines, Illinois, Elk Grove Village, Illinois, Austin, Texas, Portland, Oregon
and Fremont, California. SpeedFam U.K. is located in Hinckley, England and it
maintains approximately 9,000 square feet of owned space. SpeedFam Germany
leases approximately 2,000 square feet of leased office space in Inglefingin,
Germany.
 
LEGAL PROCEEDINGS
 
     The Company is not presently involved in any material legal proceedings.
 
     The Company's wholly owned subsidiary, FamTec AG, incorporated under the
laws of Switzerland, engaged in the manufacture, sale and service of
through-feed grinding systems for the general industrial market. As a result of
declining sales, the Company decided to terminate Swiss operations and to seek
protection under the bankruptcy laws of Switzerland. A voluntary petition for
bankruptcy was filed with Swiss authorities in November, 1993. Subsequently,
creditors' claims were adjudicated and all Swiss assets liquidated. On July 27,
1995, the Bankruptcy Administrator paid out the liquidation proceeds to
creditors, and the bankruptcy matter was closed. Under the laws of Switzerland,
members of the Board of Directors of an entity have potential personal liability
for the debts of the bankrupt entity. Mr. Farley, Chairman and Chief Executive
Officer of the Company, was a director of FamTec AG. Because no creditor filed
within the ten-day period to reserve rights against the directors of FamTec AG,
no personal liability is expected to result.
 
EMPLOYEES
 
     At May 31, 1997, the Company had 513 full time employees in the U.S. and
Europe, including 142 in manufacturing, 45 in marketing and sales, 137 in field
service, 55 in engineering, 62 in research and development and 72 in general
administration. In addition, the Company had 32 temporary contract employees
engaged principally in its assembly operations at its Chandler, Arizona and Des
Plaines, Illinois facilities. The Company believes that the use of temporary
employees allows the Company to respond more rapidly to fluctuations in assembly
and product demand and enables the Company to better control the labor component
of its manufacturing costs. None of the Company's employees is represented by a
labor union and the Company has never experienced a work stoppage or strike. The
Company considers its employee relations to be good.
 
                           JOINT VENTURE ARRANGEMENTS
 
FAR EAST JOINT VENTURE
 
     SpeedFam Co., Ltd. (together with its subsidiaries and joint ventures, the
"Far East Joint Venture"), is headquartered in Kanagawa Prefecture, Japan.
Generally, the Far East Joint Venture designs, produces and markets in the Far
East equipment similar to that produced by the Company in the U.S. The Far East
Joint Venture conducts operations primarily in Japan but has subsidiaries and
branches located in China, Hong Kong, India, Korea, Singapore, Taiwan, Thailand,
and Malaysia and owns a majority interest in a Japanese
 
                                       40
<PAGE>   42
 
subcontract manufacturing organization, Saku Seiki Co. Ltd. ("Saku Seiki"). The
Far East Joint Venture operations in China, Hong Kong, Singapore, Korea and
Thailand are primarily marketing, sales and service functions. The subsidiaries
in Taiwan and India also include manufacturing facilities where certain of the
equipment sold by the subsidiaries is produced. Through a joint venture with
Met-Coil Systems Corporation (a U.S. company), the Far East Joint Venture
manufactures and markets in the Far East sheet metal forming equipment developed
by Met-Coil Systems Corporation.
 
     Background.  During the late 1960's, the Company marketed its products in
Japan through Japanese trading companies. At that time, the Company believed
that a presence in the Japanese market would enhance its competitive position in
the U.S. as well as provide additional sources of income and access to
technology. For numerous business and cultural reasons, the Company believed it
could most effectively penetrate the Japanese market with the aid of a Japanese
partner. In 1970 the Company entered into a joint venture with a Japanese
company, Obara Corporation ("Obara"), pursuant to which the Far East Joint
Venture was formed. The Company and Obara each own a 50% interest in the Far
East Joint Venture. Obara, a privately-owned company, principally supplies
welding guns and tips and related products to the automotive industry; its
business is unrelated to that of the Company and the Far East Joint Venture.
 
     Terms of the Joint Venture Agreement.  Pursuant to the terms of an
agreement between the Company and Obara dated November 14, 1970 (the "Joint
Venture Agreement"), the Far East Joint Venture will continue as long as
SpeedFam Co., Ltd. is in corporate existence and both the Company and Obara are
shareholders. Both parties to the Joint Venture Agreement have agreed to refrain
from competing with the joint venture in Japan. The agreement may, however, be
terminated upon 90-days notification by either party in the event of a
substantial breach by the other party if such breach is not cured within the
90-day period. In the event that either the Company or Obara desires to sell its
interest in the Far East Joint Venture, it must first offer its interest to the
other party, which then has 60 days to purchase the interest at a price to be
mutually agreed upon. If the interest is not purchased within the 60-day period,
the party desiring to sell its interest may sell it to a third party free of the
right of first offer provisions, provided that the price is not less than the
price initially offered by the other party.
 
     Pursuant to the terms of a License and Technical Assistance Agreement
between the Company and SpeedFam Co., Ltd. dated November 14, 1970 (the
"Technology Agreement"), the Company licensed to the Far East Joint Venture
certain trademarks and technology, and granted to the Far East Joint Venture the
exclusive right to manufacture and sell in Japan, Korea, Taiwan, Hong Kong,
China, India, the Philippines, Thailand, Vietnam, Malaysia, Singapore and
Indonesia, and such other countries as the parties may agree to from time to
time, products similar to those manufactured and distributed by the Company. In
exchange for such rights, the Far East Joint Venture agreed to pay to the
Company a royalty of 4% of the total net sales of products sold by the Far East
Joint Venture that incorporate the technology. The Company also agreed to
provide technical assistance and to communicate to the Far East Joint Venture
all developments and improvements related to the technology. In addition, the
Far East Joint Venture agreed to communicate to the Company all developments and
improvements known to the Far East Joint Venture relating to the technology, and
the Company agreed to pay to the Far East Joint Venture a 2% royalty fee on
machines sold by the Company that utilize certain of that technology. The
Technology Agreement continued for an initial term of ten years and was
renewable for subsequent ten year periods. By oral agreement in 1980, the
Technology Agreement was extended and amended to reduce the percentage of
royalties to be paid by the Far East Joint Venture. Notwithstanding the
requirements of the Technology Agreement, although the Far East Joint Venture
had transferred technology to the Company, the Company and the Far East Joint
Venture agreed that no royalties would be paid by the Company. By oral agreement
in 1990, the Technology Agreement was extended for a new ten-year period. By
oral agreement in 1991, the Technology Agreement was amended to eliminate the
payment of royalties by either party. On July 24, 1995, the foregoing oral
agreements were confirmed in writing. Unless extended, the Technology Agreement
will expire in November 2000.
 
     Since the inception of the Far East Joint Venture, the Company and the Far
East Joint Venture have worked cooperatively on various research and development
projects and each entity has communicated significant technology to the other.
It is not anticipated that either the Company or the Far East Joint Venture
 
                                       41
<PAGE>   43
 
will pay royalties to the other in connection with the transfer of technology in
the foreseeable future, including with respect to the Company's CMP technology.
 
     Management.  SpeedFam Co., Ltd. currently has nine directors serving on its
Board of Directors, including Messrs. Farley and Kouzuma, the Chairman and Chief
Executive Officer of the Company, respectively, as well as Hiroshi Obara,
Suminori Suzuki, Ryosuke Tojo, Shinya Iida, Hatsuyuki Arai, Isao Nagahashi and
Akitoshi Yoshida. Mr. Kouzuma is the Executive Vice President and General
Manager of SpeedFam Co., Ltd. and is responsible for day to day operations and
acts as the primary liaison between the Company and Obara. Mr. Obara is the
President of the Far East Joint Venture. Mr. Suzuki, an employee of Obara, is
the senior finance officer of the Far East Joint Venture. Mr. Tojo is Managing
Director of the Far East Joint Venture and assists in the overall management of
operations. Dr. Iida is the chief technical officer and is responsible for all
research, development and engineering operations. Mr. Yoshida is Chief of the
Makuhari Techno Garden Laboratory and reports to Mr. Iida. Messrs. Arai and
Nagahashi are the directors of CMP and thin film memory disk technology,
respectively, and report to Mr. Tojo. Mr. Kunihiko Watanabe is director of sales
for the silicon wafer market and reports to Mr. Kouzuma.
 
     The Joint Venture Agreement provides limited direction with respect to the
relationship between the joint venture partners and the operation and management
of the Far East Joint Venture. To date, decisions with respect to the strategic
direction of the Far East Joint Venture have been made by the Company and Obara
from time to time on the basis of informal discussions and the relationships
forged over time by the individuals. Business transactions between the Company
and the Far East Joint Venture, including those relating to the absence of
payment of royalties on transfers of certain technology, may not be consistent
with business decisions and results that would exist between two independent
entities dealing at arms-length.
 
     Financial Information.  During the Company's 1995, 1996 and 1997 fiscal
years, the Company's share of the net earnings of the Far East Joint Venture was
$1.1 million, $4.8 million and $5.5 million, respectively, representing 66.9%,
40.3% and 27.3%, respectively, of the Company's net earnings. The Far East Joint
Venture has not paid significant dividends in the past and is expected to retain
substantially all of its earnings in the foreseeable future to support the
growth of its business. As a result, the Company's share of the net earnings of
the Far East Joint Venture has not in the past resulted and is not expected in
the future to result in a like effect on the cash flows of the Company. In
addition, in recent periods the equity in net earnings of affiliates has
increased substantially, primarily as a result of an increase in net earnings of
the Far East Joint Venture. This increase has been primarily attributable to a
strong demand for equipment, systems and other products supplied by the Far East
Joint Venture to the thin film memory disk and semiconductor wafer industries.
However, due to recent competition in the sale of equipment into the thin film
memory disk market and for other reasons, the Company does not expect that this
historical rate of earnings growth will continue and expects that earnings of
the Far East Joint Venture during its fiscal 1998 will be the same as or lower
than in fiscal 1997. During fiscal 1995, 1996 and 1997, 4.5%, 5.2% and 7.2%
respectively, of the Company's total revenue was attributable to commissions
earned on products produced by the Far East Joint Venture and which were sold by
the Company. At May 31, 1997, the Company's equity interest in the Far East
Joint Venture was $20.4 million, representing 9.9% of the Company's total assets
and 13.0% of shareholders' equity. Set forth below is certain selected financial
information with respect to the Far East Joint Venture which has been derived
from consolidated financial statements which have been audited by KPMG Peat
Marwick LLP, with the exception of the selected financial information as of and
for the three months ended July 31, 1996 and 1997 which is unaudited. In the
opinion of management, this information has been presented on the same basis as
the audited consolidated financial statements of the Far East Joint Venture
appearing elsewhere in this Prospectus, and all necessary adjustments have been
included in the amounts stated below to present fairly the unaudited quarterly
results when read in conjunction with the consolidated financial statements.
Such information should be read in conjunction with the consolidated financial
statements and notes thereto of the Far East Joint Venture appearing elsewhere
herein.

     Products and Customers.  Generally, the Far East Joint Venture designs,
produces and markets in the Far East equipment similar to that produced by the
Company in the U.S. The Far East Joint Venture's product mix is significantly
different than the Company's primarily because the Far East Joint Venture sells
substantially fewer CMP planarization systems to semiconductor device
manufacturers and because of differences in the composition of the U.S. and Far
East markets. The Far East Joint Venture also designs, produces and markets edge
and flat polishing machines for the semiconductor wafer market and pre-
deposition cleaning machines for the thin film memory disk market and, more
recently, the flat panel display market. The Company distributes certain of
these machines in the U.S. and Europe. New products recently introduced and
manufactured solely by the Far East Joint Venture include the RCPM-95, a
multiple-head radial/circumferential polisher, manufactured exclusively for
high-end thin film memory disk processing, which creates programmable polish
patterns on the disk surface allowing higher density media and improved yields.
The Far East Joint Venture also markets parts, expendables and slurries
(primarily to thin film memory disk and silicon wafer manufacturers).
 
     The Far East Joint Venture has developed and is currently manufacturing and
marketing a two head CMP system. This system is marketed primarily as a tool for
low volume production or research and development. The Company's Auriga five
head system and other CMP products are marketed and sold through the Far East
Joint Venture. The Far East Joint Venture receives a commission from the Company
for such sales in the Far East.
 
     The Far East Joint Venture's products are sold to semiconductor wafer
(primarily silicon), thin film memory disk and general industrial (primarily
quartz, ceramic and LCD glass) manufacturers. Major end user customers of the
Far East Joint Venture have included: Niigata Toshiba Ceramics Co., Ltd.
(silicon wafer manufacturer), LG Siltron, Inc. (silicon wafer manufacturer),
Toyo Kohan Co., Ltd. (thin film memory disk manufacturer), Wacker Siltron
(silicon wafer manufacturer), Kaifa Magnetics (H.K.), Ltd. (thin film memory
disk manufacturer). During the Far East Joint Venture's fiscal years 1995, 1996
and 1997, sales to certain customers through Fujimi Incorporated, acting as a
distributor, accounted for approximately 11%, 12% and 15% of net sales,
respectively.
 
     Competition.  The Far East Joint Venture competes in several distinct
markets including the semiconductor substrate equipment market, the thin film
memory disk equipment market, the general industrial equipment applications
market (primarily quartz, ceramic and LCD glass) and the slurries market. The
Far East Joint Venture competes on the basis of technology, overall cost of
ownership, product quality, price, availability, size of installed base, breadth
of product line and customer service and support. The Far East Joint Venture
faces intense competition from established competitors, some of which have
substantially
 
                                       43
<PAGE>   45
 
greater financial, engineering, manufacturing and marketing resources. In the
equipment markets served, the Far East Joint Venture generally competes with a
relatively small number of competitors which, together with the Far East Joint
Venture, provide a substantial majority of the products sold into those markets.
The Far East Joint Venture recently adopted an aggressive pricing strategy
designed to gain market share for its new automated disk polishing systems.
Although the Far East Joint Venture expects this gross margin pressure to
continue to negatively impact the Far East Joint Venture's earnings for at least
the near term, the Far East Joint Venture believes that this pricing strategy
represents an important strategic investment. In the slurries market, Fujimi
Incorporated is the provider of substantially all of the slurries sold by the
Far East Joint Venture. Fujimi Incorporated also sells directly to end users and
is a dominant supplier and distributor of slurries in the Far East region.
 
     Sales, Marketing and Service.  The Far East Joint Venture markets and sells
its products through a combination of Japanese trading companies and direct
sales personnel. As is customary in Japan, the Far East Joint Venture sells a
substantial portion of the products sold in Japan through trading companies,
although the Far East Joint Venture sales personnel have primary responsibility
for most aspects of the sale. The Far East Joint Venture maintains a field
service organization consisting of 75 persons based in the major locations where
the Far East Joint Venture maintains a presence, such as Japan, India Korea,
Singapore Taiwan and Thailand.
 
     Research, Development and Manufacturing.  The Far East Joint Venture
maintains a research and development staff of 67 persons. Research and
development efforts of the Far East Joint Venture are focused on enhancing
existing products as well as developing new products and generally cover a
broader range of products and technologies than the Company's research and
development efforts. The Company and the Far East Joint Venture have in the past
collaborated on various projects and are expected to do so in the future.
 
     The Far East Joint Venture or manufacturing subcontractors retained by the
Far East Joint Venture typically manufacture equipment and systems from
components and fabricated parts manufactured and supplied by others. Certain of
the items manufactured by others are made to the Company's specifications. A
portion of the products sold by the Far East Joint Venture are manufactured by
the Far East Joint Venture's majority owned subsidiary, Saku Seiki, and a
substantial portion are manufactured by unaffiliated third party subcontractors
for the Far East Joint Venture.
 
     Employees.  At April 30, 1997, the Far East Joint Venture had 492 full-time
employees, including 388 in Japan, 4 in Thailand, 22 in Korea, 40 in Taiwan, 17
in India, 14 in Singapore, 2 in Shanghai, 3 in Hong Kong and 2 in Malaysia. Of
these employees, 87 are engaged in manufacturing, 67 in marketing and sales, 75
in field service, 85 in engineering, 67 in research and development, 52 in
management and 59 in clerical and general administration.
 
     Certain Relationships.  The Company acts as distributor in North America
and Europe of certain machines produced by the Far East Joint Venture. During
fiscal 1995, 1996 and 1997, commissions paid to the Company relating to such
distribution amounted to approximately $2.8 million, $6.3 million and $12.4
million, respectively. Further, the Company purchases certain components used in
its machines from the Far East Joint Venture. During fiscal 1995, 1996 and 1997,
purchases of components from the Far East Joint Venture totaled approximately
$3.0 million, $5.6 million and $4.9 million, respectively.
 
     Mr. Kouzuma receives certain amounts from the Far East Joint Venture
consisting of directors' fees, bonuses and salary. In addition, both Messrs.
Farley and Kouzuma receive dividends on their individual holdings of stock in
certain of SpeedFam Co., Ltd.'s subsidiaries. Both Messrs. Farley and Kouzuma
serve as directors of SpeedFam Co., Ltd. In addition, both serve as directors of
SpeedFam Clean Systems Co. Ltd., a majority owned subsidiary of SpeedFam Co.,
Ltd. Mr. Kouzuma also serves as President of SpeedFam Clean Systems Co. Ltd. In
addition, each of Messrs. Farley and Kouzuma own 5% of the outstanding capital
stock of SpeedFam Clean Systems Co., Ltd. Messrs. Farley and Kouzuma also serve
as directors of MetCoil Ltd., SpeedFam Co. Ltd.'s 50%-owned joint venture. Mr.
Kouzuma owns 10.62% of the outstanding capital stock of Saku Seiki, a majority
owned subsidiary of SpeedFam Co., Ltd., and serves as a director of Saku Seiki.
Messrs. Farley and Kouzuma also serve as directors of several wholly owned
subsidiaries of SpeedFam Co.

FUJIMI JOINT VENTURE
 
     Pursuant to a joint venture agreement dated September 7, 1984, the Company
and Fujimi Incorporated formed the Fujimi Joint Venture, an Illinois
corporation. Each of Fujimi Incorporated and the Company owns 50% of the Fujimi
Joint Venture's common stock. Fujimi Incorporated, a publicly traded company in
Japan, is a manufacturer of slurry, abrasives and compounds in Japan. The
initial term of the joint venture agreement was for a period of five years, but
the agreement continues in effect until such time as either party terminates
upon written notice delivered to the other party upon one-year notice. The
agreement may also be terminated upon 60-days notification by either party in
the event of a breach by the other party if such breach is not cured within 60
days.
 
     The Fujimi Joint Venture was organized to sell Fujimi Incorporated products
in North and South America. The Fujimi Joint Venture distributes abrasives,
polishing pads, diamond wheels, diamond slurries and other products to the
semiconductor wafer, thin film memory disk and general industrial markets.
Notwithstanding the written terms of the joint venture agreement, the Company,
through SpeedFam U.S., has distributed a variety of products, primarily slurry,
to manufacturers of thin film memory disks. The Company has the exclusive right
to distribute Fujimi Incorporated memory disk polishing slurry in North America
until October 1, 1999. Revenue from sales of products by the Fujimi Joint
Venture were $15.8 million in fiscal 1995, $19.7 million in fiscal 1996 and
$36.6 million in fiscal 1997. For a description of other business relationships
between the Company and Fujimi Incorporated, see "Business -- Manufacturing and
Suppliers." The Fujimi Joint Venture imports a portion of the products it sells
and purchases such products in non-U.S. dollar denominated transactions. This
business is subject to foreign exchange rate fluctuations and has recently
experienced increased competition which can significantly impact operating
earnings.
 
     The Fujimi Joint Venture currently has six directors serving on its Board
of Directors, including Mr. Farley, Chairman of the Company, Mr. Kouzuma, Chief
Executive Officer of the Company, and Mr. Augur, President of SpeedFam U.S. The
other three directors, Messrs. Isamu Koshiyama, Hidetaka Niinomi and Stuart
Sawai, are representatives of Fujimi Incorporated. Day to day management of the
Fujimi Joint Venture is under the control of its president, Mr. Donald R.
Hixson. The Fujimi Joint Venture employs four full-time sales personnel.

Stock, of which 13,475,036 were currently issued and outstanding as of September

to be voted upon by the shareholders generally, including the election of
directors. Subject to the rights of holders of any Preferred Stock outstanding,
holders of Common Stock are entitled to receive such dividends as are declared
by the Board of Directors out of funds legally available therefor, and in the
event of liquidation, dissolution or winding upon of the Company, the holders of
Common Stock are entitled to share ratably in any assets remaining after payment
of the Company's liabilities. Holders of Common Stock do not have preemptive or
other subscription rights. The Common Stock currently outstanding is, and the
shares of Common Stock offered by the Company hereby will be, when issued,

authorized to fix the dividend rights and terms, redemption rights and terms,

of dividends or upon the Company's liquidation, dissolution or winding up, the
rights of the holders of the Common Stock may be adversely affected. The

ANTI-TAKEOVER STATUTES
 
     Section 7.85 of the Illinois Business Corporation Act of 1983 (the "BCA")
provides that business combinations between an Illinois corporation with a class
of securities registered under the Exchange Act or a corporation which elects to
be subject to Section 7.85 and the beneficial holder of 10% or more of the
voting power of such corporation generally require (i) the approval of 80% of
the votes of each class of stock entitled to vote and (ii) the affirmative vote
of at least a majority of the votes of each class of stock entitled to be cast
held by persons other than the 10% owner. Such requirements will not apply if
the transaction is approved by 2/3 of the disinterested directors (generally
defined as a director not affiliated or associated with the 10% owner), the
price to be paid to the shareholders of the corporation is generally the higher
of the fair market value (as defined in the statute) or the price per share paid
by the 10% owner in acquiring its shares, and certain other conditions relating
to the absence of dividend defaults, the receipt of special benefits by the 10%
owner and the provision of specified information about the transaction to the
corporation's public shareholders, are satisfied.
 
     Section 11.75 of the BCA provides that a corporation shall not engage in
any business combination with any interested shareholder (generally defined as
the beneficial owner of 15% or more of the outstanding voting shares of the
company) for a period of three years following the date that such shareholder
became an interested shareholder, unless (a) prior to such date the board of
directors of the corporation approved either the business combination or the
transaction which resulted in the shareholder becoming an interested
shareholder, or (b) upon consummation of the transaction which resulted in the
shareholder becoming an interested shareholder, the interested shareholder owned
at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding for purposes of determining the number of
shares outstanding those shares owned (i) by persons who are directors and also
officers and (ii) employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer), or (c) on or subsequent to
such date the business combination is approved by the board of directors and
authorized at an annual or special meeting of shareholders, and not by written
consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
stock which is not owned by the interested shareholder.
 
     Section 8.85 of the BCA permits directors and officers of an Illinois
corporation to consider the interests of constituencies other than the
corporation's shareholders when exercising their duties, including in the
consideration of a transaction which could result in a change of control of the
Company.
 
     The Company is automatically subject to Section 8.85 and Section 7.85 and,
depending on the final distribution of the shares offered hereby and certain
shareholder residency requirements with the State of Illinois, Section 11.75.

     The Underwriting Agreement provides that the obligations of the
Underwriters thereunder are subject to various conditions. The nature of the
Underwriters' obligations are such that they are committed to take and pay for
all of the shares offered hereby if any are purchased.
 
     The Company and the Selling Shareholders have been advised that the
Underwriters propose to offer the shares of Common Stock directly to the public
at the public offering price set forth on the cover page of this Prospectus, and
to certain selected dealers (who may include the Underwriters) at such public
offering price less a selling concession not in excess of $     per share. The
selected dealers may reallow a concession not in excess of $     per share to
certain brokers and dealers. After the initial public offering, the public
offering price, the concession to selected dealers and the reallowance may be
changed by the Underwriters.
 
     The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, and to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
     The Company has granted to the Underwriters an option to purchase up to an
aggregate of 325,500 shares of Common Stock, exercisable solely to cover
over-allotments, at the offering price to the public less the underwriting
discounts and commissions shown on the cover page of this Prospectus. Such
option may be exercised at any time until 30 days after the date of the
Underwriting Agreement. To the extent that the option is exercised, each
Underwriter will be committed, subject to certain conditions, to purchase a
number of the additional shares of Common Stock proportionate to such
Underwriter's initial commitment as indicated in the preceding table.
 
     Certain holders of shares of Common Stock of the Company, owning an
aggregate of 4,818,158 shares, have agreed that they will not, subject to
certain limited exceptions, directly or indirectly, offer, sell or otherwise
dispose of any shares of Common Stock or any securities convertible into or
exchangeable or exercisable for any such shares for a period of 90 days after
the effective date of the offering without the prior written consent of Lehman
Brothers Inc., which reserves the right to release any or all of such
shareholders from their obligations under such lock-up agreements at any time
without notice. Any such release would increase the number of shares available
for sale into the public market, which could have a material adverse effect on
the price of the Common Stock. In addition, the Company has agreed that it will
not, subject to certain limited exceptions, directly or indirectly, offer, sell
or otherwise dispose of any shares of Common Stock or any securities convertible
into or exchangeable for such shares without the prior written consent of Lehman
Brothers Inc. for 90 days after the effective date of the offering.
 
     In connection with the offering, the rules of the Commission permit the
Underwriters to engage in certain transactions that stabilize the price of the
Common Stock. Such transactions may consist of bids or purchases for the purpose
of pegging, fixing or maintaining the price of the Common Stock. In addition, if
the
 
                                       53
<PAGE>   55
 
Underwriters over-allot (i.e., if they sell more shares of Common Stock than are
set forth on the cover page of this Prospectus), and thereby create a short
position in the Common Stock in connection with the offering, the Underwriters
may reduce that short position by purchasing Common Stock in the open market. In
general, purchases of a security for the purpose of stabilization or to reduce a
syndicate short position could cause the price of the security to be higher than
it might otherwise be in the absence of such purchases. Neither the Company nor
any of the Underwriters makes any representation or prediction as to the
direction or magnitude of any effect that the transactions described above may
have on the price of the Common Stock. In addition, neither the Company nor any
of the Underwriters makes any representation that the Underwriters will engage
in such transactions or that such transactions, once commenced, will not be
discontinued without notice.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Common Stock offered hereby will be passed

matters will be passed upon for the Underwriters by Brobeck, Phleger & Harrison
LLP, San Diego, California. Mr. Charles A. Kelly, a partner of Chapman and

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors
SpeedFam International, Inc.:
 
     We have audited the accompanying consolidated balance sheets of SpeedFam
International, Inc. and consolidated subsidiaries as of May 31, 1996 and 1997,
and the related consolidated statements of earnings, stockholders' equity, and
cash flows for each of the years in the three-year period ended May 31, 1997.
These consolidated financial statements are the responsibility of the management
of SpeedFam International, Inc. Our responsibility is to express an opinion on
these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of SpeedFam
International, Inc. and consolidated subsidiaries as of May 31, 1996 and 1997,
and the results of their operations and their cash flows for each of the years
in the three-year period ended May 31, 1997 in conformity with generally
accepted accounting principles.

respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date.
 
  (f) Revenue Recognition
 
     Sales of the Company's products are recorded upon shipment or when the
product is accepted by the customer. Commission revenue from affiliates is
recorded upon shipment of product.

warranty fulfillment are accrued at the date of shipment, and are estimated by
the Company based on past experience. The accrual for product installation and

sheets, was $2,485 and $5,510 at the end of fiscal years 1996 and 1997,

* Less than 10%.
 
     Amounts due from these significant customers represented 6.7% of total
trade accounts receivable at May 31, 1997.
 
  (l) Patents and Trademarks
 
     Patents and trademarks included in other assets, in the net amount of $463
and $769 at the end of fiscal years 1996 and 1997, respectively, are amortized
on a straight-line basis over 17 years for patents and five years for
trademarks.
 
  (m) Research, Development, and Engineering
 
     Expenditures for research, development, and engineering of products and
processes are expensed as incurred.
 
  (n) Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company's management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  (o) Employee Stock Plans
 
     Effective June 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation."
In accordance with the provisions of SFAS No. 123, the Company applies
Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued
to Employees," and related interpretations in accounting for its employee stock
option and stock purchase plans and, accordingly, does not recognize
compensation cost. As prescribed by SFAS No. 123, note 10 contains a summary of
the pro forma effects on reported net earnings and earnings per share for 1996
and 1997 as if the Company had elected to recognize compensation cost based on
the fair value of the options granted at grant date.

     No provision is made for income taxes on undistributed earnings of wholly
owned non-U.S. subsidiaries and SpeedFam Co., Ltd., because it is the Company's
present intention to reinvest substantially all the earnings of these
operations. At the end of fiscal year 1997, there was approximately $22,700 of
accumulated undistributed earnings of those operations. It is not practical for
the Company to compute the amount of unrecognized deferred tax liability on the
undistributed earnings.

     In fiscal year 1996 the Company entered into an unsecured credit agreement
with two U.S. banks. The credit agreement is for a $22,500 revolving line of
credit maturing April 14, 1999. The Company must meet certain financial
objectives each year as defined in the credit agreement. During fiscal 1997, the
Company paid off the outstanding balance on the unsecured revolving line of
credit.
 
     On September 13, 1996, the Company negotiated an amendment to the $22,500
credit facility, providing for an additional $14,000 in a five-year unsecured
term loan to fund the construction of a new corporate headquarters and
manufacturing facility in Chandler, Arizona. As of May 31, 1997, no amounts were
outstanding on the term loan. Should the loan be utilized, terms of the loan
provide that principal will be repaid in fifteen (15) quarterly installments of
$350 each beginning in October 1997. The remaining outstanding balance will be
repaid at the end of the loan's term. Interest on the term loan will accrue and
be paid monthly on the outstanding balance based on a 90-day LIBOR rate plus 140
basis points. Unless drawn upon, the term loan will expire September 29, 1997.
 
     The term loan payable in monthly installments of $26 is secured by certain
machinery of SpeedFam Corporation.
 
     On October 31, 1996, SpeedFam Limited in the United Kingdom, a wholly owned
subsidiary of SpeedFam International, Inc., entered into a L950 ($1,543)
Multi-Currency Revolving Line of Credit with the London branch of a U.S. bank.
The revolving line of credit is secured by property and equipment of the
subsidiary and is payable on demand. Interest accrues on the outstanding balance
at 2.0% above the bank's base rate (6.0% at April 30, 1997) and is payable
monthly. As of April 30, 1997, no amounts were outstanding on this credit
facility.

(7) COMMITMENTS AND CONTINGENCIES
 
     During fiscal year 1996, the Company entered into a technology license
agreement related to the development of a new product introduced during fiscal
year 1997. The agreement required the payment of $400 upon signing and a final
payment of $300 was made in September 1996. The agreement also obligates the
Company to make annual royalty payments of 5.5% of the Company's net sales of
products using the licensed technology for ten years. The annual royalty
payments are subject to a minimum payment of $150 beginning in fiscal year 1998
and $200 for fiscal years 1999 to 2006.
 
     The Company and its subsidiaries occupy certain manufacturing and office
facilities and use certain equipment under noncancelable operating leases
expiring at various dates through fiscal year 2001. Rental expense aggregated
approximately $611, $917, and $1,235 in 1995, 1996, and 1997, respectively.
 
     Future minimum lease payments for all noncancelable operating leases having
a remaining term in excess of one year at the end of fiscal year 1997 are as

     All currency forward contracts outstanding at May 31, 1997 have maturities
of less than one year and are primarily to buy or sell Japanese yen in exchange
for U.S. dollars. Management believes that these contracts should not subject
the Company to undue risk from foreign exchange movements, because gains and
losses on these contracts generally offset gains and losses on the assets,
liabilities, and transactions being hedged. The fair value of these contracts
and the related deferred gains are insignificant.
 
(9) SAVINGS AND PROFIT-SHARING PLANS
 
     The Company maintains savings and profit-sharing plans for its employees.
The plans cover certain employees who meet length of service requirements.
Expense under the plans, determined by the Company's Board of Directors,
aggregated $60, $1,443, and $2,414 in 1995, 1996, and 1997, respectively.
 
(10) STOCK OPTION PLANS
 
     The Company grants options to employees under the 1991 Employee Incentive
Stock Option Plan and the 1995 Stock Plan for Employees and Directors of the
Company. Under the plans, options to purchase up to 2,500,000 shares of the
Company's authorized but unissued common stock may be granted. Prior to fiscal
year 1995, stock options were granted at 100% to 110% of the value of the
Company's common stock as determined by an established formula. In fiscal year
1995, stock options were granted at 100% to 110% of the fair value of

the Company's common stock as determined by an independent appraiser. Subsequent
to fiscal year 1995 stock options are granted at a price not less than the fair
market value on the date of grant. The stock options vest over five years (i.e.,
20% each year) with the exception of 163,800 stock options issued in 1992, which
vested immediately. The stock options expire 10 years after the grant date,
except for 71,100 stock options which expire five years after the grant date.

25 in accounting for stock-based awards to employees. Accordingly, no
compensation cost has been recognized for the stock option and stock purchase
plans. Had compensation cost for the Company's stock option and stock purchase
plans been determined based on the fair value at the grant date for awards in
1996 and 1997 consistent with the

</TABLE>
 
     In accordance with the provisions of SFAS No. 123, pro forma net earnings
reflects only options granted in 1996 and 1997. Therefore, the full impact of
calculating compensation cost of options under SFAS No. 123 is not reflected in
the pro forma net income amounts presented above because compensation cost is
reflected over the options vesting period of five years, and compensation cost
for options granted prior to June 1, 1995 is not considered.
 
     In calculating pro forma compensation, the fair value of each option is
estimated on the date of grant using the Black-Scholes option-pricing model,
with the following weighted average assumptions for grants made in 1996 and
1997.

     The pro forma net earnings and earnings per share listed above includes
expense related to the Company's 1995 Employee Stock Purchase Plan. The fair

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
(14) OFFERINGS OF COMMON STOCK
 
     On October 26, 1995, the Company completed its initial public offering of
common stock. The Company issued 2,927,500 shares of common stock and received
proceeds of $28,284, net of underwriters' discounts and commissions and offering
expenses.
 
     On February 20, 1997, the Company completed an additional public offering
of common stock. The Company issued 2,500,000 shares of common stock and
received proceeds of $77,673, net of underwriters' discounts and commissions and
offering expenses.
 
(15) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments at May 31, 1996 and 1997 include cash
equivalents, trade receivables, trade payables, noncurrent receivables, foreign
exchange contracts, and long-term debt. The carrying value of cash equivalents,
trade receivables, and trade payables approximates fair value because of the
short maturity of these instruments. The fair value of the Company's noncurrent
receivables and long-term debt is not materially different from their financial
statement carrying values.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors
SpeedFam Co., Ltd.:
 
     We have audited the accompanying consolidated balance sheets of SpeedFam
Co., Ltd. and consolidated subsidiaries as of April 30, 1996 and 1997, and the
related consolidated statements of earnings, stockholders' equity, and cash
flows for each of the years in the three-year period ended April 30, 1997. These
consolidated financial statements are the responsibility of the management of
SpeedFam Co., Ltd. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of SpeedFam Co.
Ltd. and consolidated subsidiaries as of April 30, 1996 and 1997, and the
results of their operations and their cash flows for each of the years in the
three-year period ended April 30, 1997, in conformity with generally accepted
accounting principles.

equipment and consumables, through-feed grinders, cleaning machines, and
measuring equipment used in high technology industries.
 
  (a) Basis of Presentation

  (d) Short-term Investments
 
     The Company classifies its debt and equity securities into one of three
categories: trading, available-for-sale, or held-to-maturity. Trading securities
are bought and held principally for the purpose of selling them in the near
term. Held-to-maturity securities are those securities in which the Company has
the ability and intent to hold the security until maturity. All other securities
not included in trading or held-to-maturity are classified as
available-for-sale.
 
     Trading and available-for-sale securities are recorded at fair value.
Held-to-maturity securities are recorded at amortized cost, adjusted for the
amortization or accretion of premiums or discounts. Unrealized holding gains and
losses, net of the related tax effect, on available-for-sale securities are
excluded from earnings and are reported as a separate component of stockholders'
equity until realized. Realized gains and losses from the sale of
available-for-sale securities are determined on a specific identification basis.
 
     A decline in the market value of any available-for-sale or held-to-maturity
security below cost that is deemed to be other than temporary results in a
reduction in carrying amount to fair value. The impairment is charged to
earnings and a new cost basis for the security is established. Premiums and
discounts are amortized or accreted over the life of the related
held-to-maturity security as an adjustment to yield using the effective interest
method. Dividend and interest income are recognized when earned.
 
  (e) Property, Plant, and Equipment
 
     Property, plant, and equipment are stated at cost. Depreciation is provided
on the declining balance method over the estimated useful lives of the assets.
Depreciation expense was $2,312, $2,148, and $3,542 in fiscal years 1995, 1996,
and 1997, respectively. The estimated useful lives of the assets are as follows:

    Buildings and improvements.............................................   3 to 65 years
    Machinery and equipment................................................   3 to 12 years
    Furniture and fixtures.................................................   2 to 20 years
    Leasehold improvements.................................................         2 years
</TABLE>
 
  (f) Inventories
 
     Inventories are stated at the lower of cost, determined principally by the
first-in, first-out (FIFO) method, or market.
 
  (g) Income Taxes
 
     Income taxes are accounted for under the asset and liability method. Under
the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.
 
  (h) Revenue Recognition
 
     Sales of the Company's products are recorded upon shipment.

  (i) Warranty Costs
 
     Generally, the Company provides a one-year warranty against manufacturer's
defects on all machines sold. Provision for warranty expense is provided based
upon an estimate derived from experience factors.
 
  (j) Foreign Currency Translation
 
     Assets and liabilities of the Company's non-Japanese operations have been
translated using the exchange rates in effect at the balance sheet dates or
balance sheet date of the subsidiary, if different. Results of operations are
translated using the average exchange rates prevailing throughout the period.
Local currencies are considered the functional currencies of the Company's
non-Japanese entities. Foreign currency exchange rates used to translate the
financial statements are summarized below:

10.5%, 11.2%, and 12.5% of net sales in fiscal years 1995, 1996, and 1997,
respectively.

     Research and development expense amounted to approximately $1,748, $6,651,
and $11,488 in fiscal years 1995, 1996, and 1997, respectively. Such
expenditures are expensed as incurred.
 
  (m) Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company's management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  (n) Reclassifications
 
     Certain amounts in the prior year financial statements have been
reclassified to conform with the 1997 financial statement presentation.

marketable securities aggregated $15 and $184 at the end of fiscal years 1996
and 1997, respectively.

     No provision is made for income taxes on undistributed earnings of
non-Japan subsidiaries. The Company believes that the amount of income taxes
that would be incurred if these earnings were remitted would not be significant
because of available tax credits.
 
     The Company's corporate tax returns through April 30, 1994 have been
examined by the Japanese tax authorities.

     At the end of fiscal year 1997, outstanding commitments for the purchase of
property, plant, and equipment were approximately $468.
 
     At April 30, 1997, the Singapore branch of the Company has an outstanding
claim amounting to $285 against the branch for losses and damages suffered by a
plaintiff as a result of the branch's alleged failure to meet certain
specifications for a machine sold to the plaintiff. The branch is contesting the
claim and has filed a defense in respect thereof. Based on legal advice
obtained, Company management is of the opinion that no ultimate liability will
arise. Accordingly, no provision has been made in the financial statements with
respect to this claim.
 
(10) PENSION AND SEVERANCE BENEFITS
 
     The Company maintains pension and severance benefit plans for its
employees. Employees who leave the Company upon retirement because of age or
sever their connection with the Company for reasons other than dismissal for
cause are entitled to lump-sum payments based on their current rate of pay and
length of service.
 
     Effective June 1, 1984 the Company adopted an insured pension plan which
also covers employees of SpeedFam Clean Systems Co., Ltd., the terms of which
provide for the ultimate funding of retirement benefits when due. Premiums paid
under the insured plan constitute the funding of the current costs of the
liability under the plan and the funding of the related past service costs over
a 15-year period.
 
     The funded status of the insured pension plan at the end of fiscal years
1996 and 1997 is as follows:

     Plan assets represent the Company's share of funds invested by a trustee in
pooled accounts comprised of cash in banks, securities, and real estate.
 
     A separate retirement benefits program for directors and statutory auditors
is not covered by the pension plan described above. The program provides that
directors and statutory auditors who retire or sever their connection with the
Company are entitled to lump-sum payments based on current rates of pay,
determined according to their title and the length of service. Directors and
statutory auditors may also be granted, at the discretion of the Company,
additional lump-sum payments for meritorious service. It is not the policy of
the Company to fund these retirement and severance benefits, but provision has
been made in the financial statements for the estimated accrued liabilities
under the plan. The liability related to these retirement benefits included in
the accompanying consolidated balance sheets at the end of fiscal years 1996 and
1997 amounted to $3,150 and $3,820, respectively. The plan was amended during
fiscal year 1996 and the resulting past service costs of $1,008 are being
amortized over a period of five years. Unamortized past service cost at the end
of fiscal years 1996 and 1997 amounting to $883 and $548 is classified as other
assets in the accompanying consolidated balance sheets. The retirement benefit
expenses amounted to $181, $520, and $1,545 in fiscal years 1995, 1996, and
1997, respectively.
 
     Two subsidiaries of the Company have separate employee retirement and
severance plan arrangements. Payments with respect to voluntary severance are
less in amount than payments for involuntary severance and retirement. The
subsidiaries have recorded estimated liabilities in the accompanying
consolidated balance sheets at the end of fiscal years 1996 and 1997 of $272 and
$228, respectively, based upon the amount, net of the benefits to be paid by a
government-sponsored small enterprise mutual aid retirement fund, which would be
payable if all employees had to retire voluntarily. Plan assets plus the accrued
liability approximate vested benefits. The expense related to these employee
retirement and severance plans amounted to $20, $222, and $67 in fiscal years
1995, 1996, and 1997, respectively. The Company believes that the effect of not
adopting SFAS No. 87, "Employers' Accounting for Pensions," for these plans is
not material to the consolidated financial statements.
 
(11) LEGAL RESERVE AND CASH DIVIDENDS
 
     The Japanese Commercial Code provides that earnings in an amount equal to
at least 10% of retained earnings be appropriated as a legal reserve, until such
reserve equals 25% of stated common stock. This legal reserve is not available
for dividends but may be used to reduce a deficit or may be transferred to
stated common stock. Certain non-Japanese subsidiaries are also required to
appropriate their earnings to legal reserves under the laws of the respective
countries. The legal reserve included as a component of retained earnings at the
end of fiscal years 1996 and 1997 amounted to $513 and $523, respectively.

(13) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments at April 30, 1996 and 1997 include cash
equivalents, trade receivables, short-term investments, short-term loans, trade
payables, noncurrent receivables, long-term debt, and obligations under capital
leases. The carrying amount of cash equivalents, trade receivables, short-term
loans, and trade payables approximates fair value because of the short maturity
of these instruments. The fair value of short-term investments has been
determined based on quoted market prices and approximates their financial
statement carrying values. The fair value of the Company's noncurrent
receivables and long-term debt has been determined based on discounted cash
flows using current interest rates of similar instruments, and is not materially
different from their financial statement carrying values.

asserted against or incurred by them in such capacity or arising out of their
status as such whether or not the Company would have the power to indemnify such
director, officer, employee or agent against such liability under the applicable
provisions of the Act or Bylaws. The Company currently maintains a directors and
officers liability policy in the amount of $5 million.

ITEM 17.  UNDERTAKINGS.
 
     (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
so that time shall be deemed to be the initial bona fide offering thereof.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under "Item
15 -- Indemnification of Directors and Officers" above, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
     (c) The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of Prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of Prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

Dear Ladies and Gentlemen:

"Company") and certain shareholders of the Company named in Schedule 2 hereto

the Option Stock, if purchased, are hereinafter collectively called the "Stock."
This is to confirm the agreement concerning the purchase of the Stock from the
Company and the Selling Shareholders by the Underwriters.

         1.       Representations, Warranties and Agreements of the Company. The
Company represents, warrants and agrees that:

         reference therein pursuant to Item 12 of Form S-3 which were filed
         under the Securities Exchange Act of 1934, as amended (the "Exchange

         qualification, and have all power and authority necessary to own or
         hold their respective properties and to conduct the businesses in which
         they are engaged;

                  (d) The Company has an authorized capitalization as set forth
         in the Prospectus, and all of the issued shares of capital stock of the
         Company have been duly and validly authorized and issued, are fully
         paid and non-assessable and conform in all material respects to the
         description thereof contained in the Prospectus; and all of the issued

                  (j) Neither the Company nor any of its Subsidiaries has
         sustained, since the date of the latest audited financial statements

         business from fire, explosion, flood or other calamity, whether or not
         covered by insurance, or from any labor dispute or court or

         or results of operations of the Company and its Subsidiaries taken as a
         whole, otherwise than as set forth or contemplated in the Prospectus.

         conformity with generally accepted accounting principles applied on a

                  (l) KPMG Peat Marwick LLP, who have audited certain financial

         marketable title to all personal property owned by them, in each case
         free and clear of all liens, encumbrances and defects except such as
         are described in the Prospectus or such as do not materially affect the
         value of such property and do not materially interfere with the use
         made and proposed to be made of such property by the Company and its
         Subsidiaries; and all real


                                       3.

         property and buildings held under lease by the Company and its
         Subsidiaries are held by them under valid, subsisting and enforceable
         leases, except as enforcement may be limited by applicable bankruptcy,
         insolvency, reorganization, moratorium, or other similar laws relating
         to or affecting creditors, rights generally or by general equitable
         principles, and with such exceptions as are not material and do not
         interfere with the use made and proposed to be made of such property
         and buildings by the Company and its Subsidiaries.

                  (n) The Company and each of its Subsidiaries carry, or are
         covered by, insurance in such amounts and covering such risks as is
         adequate for the conduct of their respective businesses and the value
         of their respective properties and as is customary for companies
         engaged in similar businesses in similar industries.

                  (o) The Company and each of its Subsidiaries own or possess
         adequate rights to use all material patents, patent applications,
         trademarks, service marks, trade names, trademark registrations,
         service mark registrations, copyrights and licenses necessary for the
         conduct of their respective businesses and have no reason to believe
         that the conduct of their respective businesses will conflict with, and
         have not received any notice of any claim by third parties that the
         Company or any of its Subsidiaries is infringing on the intellectual
         property rights of such third parties.

                  (p) There are no legal or governmental proceedings pending to
         which the Company or any of its Subsidiaries is a party or of which any
         property or assets of the Company or any of its Subsidiaries is the
         subject which, if determined adversely to the Company or any of its
         Subsidiaries, might have a material adverse effect on the consolidated
         financial position, shareholders' equity, results of operations,
         business or prospects of the Company and its Subsidiaries, taken as a
         whole; and to the best of the Company's knowledge, no such proceedings
         are threatened or contemplated by governmental authorities or
         threatened by others.

                  (q) There are no contracts or other documents which are
         required to be described in the Prospectus or filed as exhibits to the
         Registration Statement by the Securities Act or by the Rules and
         Regulations which have not been described in the Prospectus or filed as
         exhibits to the Registration Statement or incorporated therein by
         reference as permitted by the Rules and Regulations.

                  (r) No labor disturbance by the employees of the Company
         exists or, to the knowledge of the Company, is imminent which might be
         expected to have a material adverse effect on the consolidated
         financial position, shareholders' equity, results of operations,
         business or prospects of the Company and its Subsidiaries, taken as a
         whole.

                  (s) The Company is in compliance in all material respects with
         all presently applicable provisions of the Employee Retirement Income
         Security Act of 1974, as amended, including the regulations and
         published interpretations thereunder ("ERISA"); no "reportable event"
         (as defined in ERISA) has occurred with respect to any "pension plan"
         (as defined in ERISA) for which the Company would have any liability;
         the Company has not incurred and does not expect to incur liability
         under (i) Title IV of ERISA with respect to termination of, or
         withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the
         Internal Revenue Code of 1986, as amended, including the regulations
         and published interpretations thereunder (the "Code"); and each
         "pension plan" for which the Company would have any liability that is
         intended to be qualified under Section 401(a) of the Code is so
         qualified in all material respects and, to the best knowledge of the
         Company, nothing has occurred, whether by action or by failure to act,
         which would cause the loss of such qualification.

                  (t) The Company has filed all federal, state and local income
         and franchise tax returns required to be filed through the date hereof
         and has paid all taxes shown as due thereon, and no tax deficiency has
         been determined adversely to the Company or any of its Subsidiaries
         which has had (nor does the Company have any knowledge of any tax
         deficiency which, if determined adversely to the Company or any of its
         Subsidiaries, might have) a material adverse effect on the consolidated
         financial


                                       4.

         position, shareholders' equity, results of operations, business or
         prospects of the Company and its Subsidiaries, taken as a whole.

                  (u) Since the date as of which information is given in the
         Prospectus through the date hereof, and except as may otherwise be

         Company's stock option plans or stock purchase plan or as contemplated
         by Section 1(i) above), (ii) incurred any material liability or
         obligation, direct or contingent, other than liabilities and

         of business or (iv) declared or paid any dividend on its capital stock.

                  (v) The Company (i) makes and keeps accurate books and records
         and (ii) maintains internal accounting controls which provide
         reasonable assurance that (A) transactions are executed in accordance
         with management's authorization, (B) transactions are recorded as
         necessary to permit preparation of its financial statements and to
         maintain accountability for its assets, (C) access to its assets is
         permitted only in accordance with management's authorization and (D)
         the reported accountability for its assets is compared with existing
         assets at reasonable intervals.

                  (w) Neither the Company nor any of its Subsidiaries (i) is in
         violation of its charter or by-laws, (ii) is in default in any material
         respect, and no event has occurred which, with notice or lapse of time
         or both, would constitute such a default, in the due performance or
         observance of any term, covenant or condition contained in any material
         indenture, mortgage, deed of trust, loan agreement or other agreement
         or instrument to which it is a party or by which it is bound or to
         which any of its properties or assets is subject or (iii) is in
         violation in any material respect of any law, ordinance, governmental
         rule, regulation or court decree to which it or its property or assets
         may be subject or has failed to obtain any material license, permit,
         certificate, franchise or other governmental authorization or permit
         necessary to the ownership of its property or to the conduct of its
         business.

                  (x) To the best knowledge of the Company and its Subsidiaries,
         neither the Company nor any of its Subsidiaries, nor any director,
         officer, agent, employee or other person associated with or acting on
         behalf of the Company or any of its Subsidiaries, has used any
         corporate funds for any unlawful contribution, gift, entertainment or

                  (y) There has been no storage, disposal, generation,
         manufacture, refinement, transportation, handling or treatment of toxic
         wastes, medical wastes, hazardous wastes or hazardous substances by the
         Company or any of its Subsidiaries (or, to the knowledge of the
         Company, any of their predecessors in interest) at, upon or from any of
         the property now or previously owned or leased by the Company or its
         Subsidiaries in violation of any applicable law, ordinance, rule,
         regulation, order, judgment, decree or permit or which would require
         remedial action under any applicable law, ordinance, rule, regulation,
         order, judgment, decree or permit, except for any violation or remedial
         action which would not have, or could not be reasonably likely to have,
         singularly or in the aggregate with all such violations and remedial
         actions, a material adverse effect on the general affairs, management,
         financial position, shareholders' equity or results of operations of
         the Company and its Subsidiaries; there has been no material spill,
         discharge, leak, emission, injection, escape, dumping or release of any
         kind onto such property or into the environment surrounding such
         property of any toxic wastes, medical wastes, solid wastes, hazardous
         wastes or hazardous substances due to or caused by the Company or any

         Subsidiaries have knowledge, except for any such spill, discharge,
         leak, emission, injection, escape, dumping or release which would not
         have or would not be reasonably likely to have, singularly or in the
         aggregate with all such spills, discharges, leaks, emissions,
         injections, escapes, dumpings and releases, a material adverse effect
         on the general affairs, management, financial position, shareholders'
         equity or results of operations of the Company and

         its subsidiaries; and the terms "hazardous wastes", "toxic wastes",
         "hazardous substances" and "medical wastes" shall have the meanings

         filed with the Commission, complied and will comply in all material
         respects with the requirements of the Exchange Act and the rules and
         regulations of the Commission under the Exchange Act, and, when read
         together with the other information in the Prospectus, at the time the
         Registration Statement and any amendments thereto become effective and
         at the First Delivery Date and the Second Delivery Date, if any, will
         not contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         are made, not misleading.

         2.       Representations, Warranties and Agreements of the Selling
Shareholders. Each Selling Shareholder (except as otherwise set forth in
subsections (f) and (g)), severally and not jointly represents, warrants and
agrees that:

                  (a) Upon delivery of shares of Stock to be sold by the Selling
         Shareholder hereunder and payment therefor pursuant hereto, good and
         valid title to such shares, free and clear of all liens, encumbrances,
         equities or claims, will pass to the several Underwriters assuming they
         acquire without notice of any adverse claim.

                  (b) Such Selling Shareholder has placed in custody under a
         custody agreement (the "Custody Agreement" and, together with all other
         similar agreements executed by the other Selling Shareholders, the
         "Custody Agreements") with Firstar Trust Company as custodian (the
         "Custodian"), for delivery under this Agreement, certificates in
         negotiable form (with signature guaranteed by a commercial bank or
         trust company having an office or correspondent in the United States or
         a member firm of the New York or American Stock Exchanges) representing
         the shares of Stock to be sold by such Selling Shareholder hereunder.

                  (c) Such Selling Shareholder has duly and irrevocably executed
         and delivered a power of attorney (the "Power of Attorney" and,
         together with all other similar agreements executed by the other
         Selling Shareholders, the "Powers of Attorney") appointing James N.
         Farley and Roger K. Marach as attorneys-in-fact, with full power of
         substitution, and with full authority (exercisable by any one or more
         of them) to execute and deliver this Agreement and to take such other
         action as may be necessary or desirable to carry out the provisions
         hereof on behalf of the Selling Shareholder.

                  (d) Such Selling Shareholder has full right, power and
         authority to enter into this Agreement, the Power of Attorney and the
         Custody Agreement; the execution, delivery and performance of this
         Agreement, the Power of Attorney and the Custody Agreement by or on
         behalf of such Selling Shareholder and the consummation by such Selling
         Shareholder of the transactions contemplated hereby and thereby will
         not conflict with or result in a breach or violation of any of the
         terms or provisions of, or constitute a default under, any indenture,
         mortgage, deed of trust, loan agreement or other agreement or
         instrument to which such Selling Shareholder is a party or by which
         such Selling Shareholder is bound or to which any of the property or
         assets of such Selling Shareholder is subject, nor will such actions
         result in any violation of the provisions of the charter or by-laws of
         such Selling Shareholder, the articles of partnership of such Selling
         Shareholder, or any statute or any order, rule or regulation of


                                       6.
<PAGE>   7
         any court or governmental agency or body having jurisdiction over such
         Selling Shareholder or the property or assets of such Selling
         Shareholder; and, except for the registration of the Stock under the
         Securities Act and such consents, approvals, authorizations,
         registrations or qualifications as may be required under the Exchange
         Act and applicable state securities laws in connection with the
         purchase and distribution of the Stock by the Underwriters, no consent,
         approval, authorization or order of, or filing or registration with,
         any such court or governmental agency or body is required for the
         execution, delivery and performance of this Agreement, the Power of
         Attorney or the Custody Agreement by such Selling Shareholder and the
         consummation by such Selling Shareholder of the transactions
         contemplated hereby and thereby, except such as may be required by the
         Securities or Blue Sky laws of the various states in connection with
         the offer and sale of the shares of stock and clearance of such
         offering of the Stock with the NASD.

                  (e) Such Selling Shareholder has not taken and will not take,
         directly or indirectly, any action which is designed to or which has
         constituted or which might reasonably be expected to cause or result in
         the stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the shares of the Stock.

                  (f) James N. Farley (the "Key Selling Shareholder") represents
         and warrants that the Registration Statement and the Prospectus and any
         further amendments or supplements to the Registration Statement or the
         Prospectus will, when they become effective or are filed with the
         Commission, as the case may be, do not and will not, as of the
         applicable effective date (as to the Registration Statement and any
         amendment thereto) and as of the applicable filing date (as to the
         Prospectus and any amendment or supplement thereto) contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated herein or necessary to make the statements therein not
         misleading, but only with reference to information relating to the Key
         Selling Shareholder furnished in writing by or on behalf of the Key
         Selling Shareholder expressly for use in the Registration Statement or
         Prospectus, and provided that no representation or warranty be made as
         to information contained in or omitted from the Registration Statement
         or the Prospectus in reliance upon an in conformity with written
         information furnished to the Company through the Representatives by or
         on behalf of any Underwriter specifically for inclusion therein.

                  (g) The Key Selling Shareholder has no reason to believe
         that the representations and warranties of the Company contained in
         Section 1 hereof are not materially true and correct, is familiar
         with the Registration Statement and the Prospectus (as amended or
         supplemented) and has no knowledge of any material fact, condition or
         information not disclosed in the Registration Statement, as of the
         effective date, or the Prospectus (or any amendment or supplement
         thereto), as of the applicable filing date, which has adversely
         affected or may adversely affect the business of the Company and the
         Subsidiaries, taken as a whole, and is not prompted to sell shares of
         Common Stock by any information concerning the Company which is not set
         forth in the Registration Statement and the Prospectus.

         3.       Purchase of Stock by the Underwriters. On the basis of the
representations and warranties contained in, and subject to the terms and
conditions of, this Agreement, the Company agrees to sell 2,000,000 shares of
the Firm Stock and each Selling Shareholder hereby agrees to sell the number of
shares of the Firm Stock set opposite its name in Schedule 2 hereto, severally
and not jointly, to the several Underwriters and each of the Underwriters,
severally and not jointly, agrees to purchase the number of shares of the Firm
Stock set opposite that Underwriter's name in Schedule 1 hereto. Each
Underwriter shall be obligated to purchase from the Company, and from each
Selling Shareholder, that number of shares of the Firm Stock which represents
the same proportion of the number of shares of the Firm Stock to be sold by the
Company, and by each Selling Shareholder, as the number of shares of the Firm
Stock set forth opposite the name of each Underwriter in Schedule 1 represents
the total number of shares of the Firm Stock to be purchased by all of the
Underwriters pursuant to this Agreement. The respective purchase obligations of
the Underwriters with respect to the Firm Stock shall be rounded among the
Underwriters to avoid fractional shares, as the Representatives may determine.

                  In addition, the Company grants to the Underwriters an option
to purchase up to 325,500 shares of Option Stock. Such option is granted
solely for the purpose of covering over-allotments in the sale of Firm Stock and
is exercisable as provided in Section 5 hereof. Shares of Option Stock shall be
purchased from the Company for the account of the Underwriters in proportion to
that number of shares of the Option Stock which represents the same proportion
of the number of shares of the Firm Stock to be sold by the Company as the
number of shares of the Firm Stock set forth opposite the name of such
Underwriter in Schedule 1 represents of the total number of shares of the Firm
Stock to be purchased by all of the Underwriters pursuant to this Agreement. The
respective purchase obligations of each Underwriter with respect to the Option
Stock shall be adjusted by the Representatives so that no Underwriter shall be
obligated to purchase Option Stock other than in 100 share amounts. The price of
both the Firm Stock and any Option Stock shall be $_____ per share.

                  The Company and the Selling Shareholders shall not be
obligated to deliver any of the Stock to be delivered on the First Delivery Date
or the Second Delivery Date (as hereinafter defined), as the case may be, except
upon payment for all the Stock to be purchased on such Delivery Date as provided
herein.

         4.       Offering of Stock by the Underwriters. Upon authorization
by the Representatives of the release of the Firm Stock, the several
Underwriters propose to offer the Firm Stock for sale upon the terms and
conditions set forth in the Prospectus.

         5.       Delivery of and Payment for the Stock. Delivery of and
payment for the Firm Stock shall be made at the office of Chapman and Cutler,
Chicago, Illinois at 9:00 A.M., central time, on the fourth full business day
following the date of this Agreement or at such other date or place as shall be
determined by agreement between the Representatives and the Company. Such date
and time are sometimes referred to as the "First Delivery Date." On the First
Delivery Date, the Company and the Selling Shareholders shall deliver or cause
to be delivered certificates representing the Firm Stock to the Representatives
for the account of each Underwriter against payment to or upon the order of the
Company and the Selling Shareholders of the purchase price by certified or
official bank check or checks payable or wire transfer in immediately available
(same-day) funds. Time shall be of the essence, and delivery at the time and
place specified pursuant to this Agreement is a further condition of the
obligation of each Underwriter hereunder. Upon delivery, the Firm Stock shall be
registered in such names and in such denominations as the Representatives shall
request in writing not less than two full business days prior to the First
Delivery Date. For the purpose of expediting the checking and packaging of the
certificates for the Firm Stock, the Company and the Selling Shareholders shall
make the certificates representing the Firm Stock available for inspection by
the Representatives in New York, New York, not later than 2:00 P.M., New York
City time, on the business day prior to the First Delivery Date.

                  At any time on or before the thirtieth day after the date of
this Agreement the option granted in Section 3 may be exercised by written
notice being given to the Company by the Representatives. Such notice shall set
forth the aggregate number of shares of Option Stock as to which the option is
being exercised, the names in which the shares of Option Stock are to be
registered, the denominations in which the shares of Option Stock are to be
issued and the date and time, as determined by the Representatives, when the
shares of Option Stock are to be delivered; provided, however, that such date
and time shall not be earlier than the First Delivery Date nor earlier than the
second full business day after the date on which the option shall have been
exercised nor later than the fifth business day after the date on which the
option shall have been exercised. The date and time the shares of Option Stock
are delivered are sometimes referred to as the "Second Delivery Date" and the
First Delivery Date and the Second Delivery Date are sometimes each referred to
as a "Delivery Date".

                  Delivery of and payment for the Option Stock shall be made at
the place specified in the first sentence of the first paragraph of this Section
5 (or at such other place as shall be determined by agreement between the
Representatives and the Company) at 9:00 A.M., central time, on the Second
Delivery Date. On the Second Delivery Date, the Company shall deliver or cause
to be delivered the certificates representing the Option Stock to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company of the purchase price by certified or official bank
check or checks payable or wire transfer in immediately available (same-day)
funds. Time shall be of the essence, and delivery at the time and place
specified pursuant to this Agreement is a further condition of the obligation of
each Underwriter hereunder.

                  to do business and are in good standing as foreign
                  corporations in each jurisdiction in which their respective
                  ownership or lease of property or the conduct of their
                  respective businesses requires such qualification, except
                  where the failure to so qualify would not have a material
                  adverse effect on the financial condition, earnings,
                  operations, business or business prospects of such
                  corporation, and have all power and authority necessary to own

                  description thereof contained in the Prospectus;

                           (iii) There are no preemptive or other rights that
                  have not been properly waived to subscribe for or to purchase,
                  nor any restriction upon the voting or transfer of, any shares

                  prospects of the Company and its Subsidiaries, taken as a
                  whole; and, to the best of such counsel's knowledge, no such

                  date specified therein and no stop order suspending the
                  effectiveness of the Registration Statement has been issued
                  and, to the

                  knowledge of such counsel, no proceeding for that purpose is
                  pending or threatened by the Commission;

                           (vi) The Registration Statement and the Prospectus
                  and any further amendments or supplements thereto made by the

                  statements and related schedules therein, as to which such
                  counsel need express no opinion) comply as to form in all
                  material respects with the requirements of the Securities Act
                  and the Rules and Regulations;

                           (vii) To the best of such counsel's knowledge, there
                  are no contracts or other documents which are required to be
                  described in the Prospectus or filed as exhibits to the
                  Registration Statement by the Securities Act or by the Rules

                  exhibits to the Registration Statement or incorporated therein
                  by reference as permitted by the Rules and Regulations;

                           (viii) This Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (ix) The issue and sale of the shares of Stock being
                  delivered on such Delivery Date by the Company and the
                  compliance by the Company with all of the provisions of this
                  Agreement and the consummation of the transactions
                  contemplated hereby will not conflict with or result in a
                  breach or violation of any of the terms or provisions of, or
                  constitute a default under, any indenture, mortgage, deed of
                  trust, loan agreement or other agreement or instrument known
                  to such counsel to which the Company or any of its
                  Subsidiaries is a party or by which the Company or any of its

                  nor will such actions result in any violation of the
                  provisions of the charter or by-laws of the Company or any of
                  its Subsidiaries or any statute or any order, rule or
                  regulation known to such counsel of any court or governmental
                  agency or body having jurisdiction over the Company or any of
                  its Subsidiaries or any of their properties or assets; and,
                  except for the registration of the Stock under the Securities
                  Act and such consents, approvals, authorizations,
                  registrations or qualifications as may be required under the
                  Exchange Act and applicable state securities laws in
                  connection with the purchase and distribution of the Stock by
                  the Underwriters, no consent, approval, authorization or order

                  governmental agency or body is required for the execution,
                  delivery and performance of this Agreement by the Company and
                  the consummation of the transactions contemplated hereby; and

                           (x) To the best of such counsel's knowledge, there
                  are no contracts, agreements or understandings between the
                  Company and any person granting such person the right (other
                  than rights which have been waived or satisfied) to require
                  the Company to file a registration statement under the
                  Securities Act with respect to any securities of the Company
                  owned or to be owned by such person or to require the Company
                  to include such securities in the securities registered
                  pursuant to the Registration Statement or in any securities
                  being registered pursuant to any other registration statement
                  filed by the Company under the Securities Act.

                           In rendering such opinion, such counsel may (i) state
                  that its opinion is limited to matters governed by the Federal
                  laws of the United States of America and the laws of the State
                  of Illinois, and (ii) as to questions of fact upon
                  representations or certificates of officers of the Company and
                  of government officials, in which case their opinion is to
                  state that they are so relying and that they have no knowledge
                  of any material misstatement or inaccuracy in such opinions,
                  representations or certificates. Copies of any opinion,
                  representation or certificate so relied upon shall be
                  delivered to the Representatives and to the Representatives'
                  counsel. Such counsel shall also have furnished to the
                  Representatives a written statement, addressed to the

                  substance satisfactory to the Representatives, to the effect
                  that based on the foregoing and with no independent check or
                  verification thereof, no facts have come to the attention of
                  such counsel which lead it to believe that the Registration
                  Statement (other than the financial statements, the notes
                  thereto and other financial and statistical data included
                  therein or omitted therefrom, as to which such counsel need
                  express no view), as of the Effective Date, contained any
                  untrue statement of a material fact or omitted to state a
                  material fact required to be stated therein or necessary in
                  order to make the statements therein not misleading, or that
                  the Prospectus (other than the financial statements, the notes
                  thereto and other financial and statistical data included
                  therein or omitted therefrom, as to which such counsel need
                  express no view) contains any untrue statement of a material
                  fact or omits to state a material fact required to be stated
                  therein or necessary in order to make the statements therein,
                  in light of the circumstances under which they were made, not
                  misleading.

                  (e)      Chapman and Cutler shall have furnished to the 
         Representatives its written opinion, as counsel to the Selling
         Shareholders, addressed to the Underwriters and dated the First
         Delivery Date, in form and substance reasonably satisfactory to the
         Representatives, to the effect that:

                           (i) Each Selling Shareholder has full right, power
                  and authority to enter into this Agreement, the Power of

                  and performance of this Agreement, the Power of Attorney and
                  the Custody Agreement by each Selling Shareholder and the
                  consummation by each Selling Shareholder of the transactions
                  contemplated hereby and thereby will not conflict with or
                  result in a breach or violation of any of the terms or
                  provisions of, or constitute a default under, any statute, any
                  indenture, mortgage, deed of trust, loan agreement or other
                  agreement or instrument known to such counsel to which such
                  Selling Shareholder is a party or by which such Selling
                  Shareholder is bound or to which any of the property or assets
                  of such Selling Shareholder is subject, nor will such actions
                  result in any violation of the provisions of the charter or
                  by-laws or the articles of partnership of any Selling
                  Shareholder, or any statute or any order, rule or regulation
                  known to such counsel of any court or governmental agency or
                  body having jurisdiction over any such Selling Shareholder or
                  the property or assets of any Selling Shareholder; and, except
                  for the registration of the Stock under the Securities Act and
                  such consents, approvals, authorizations, registrations or
                  qualifications as may be required under the Exchange Act and
                  applicable state securities laws in connection with the
                  purchase and distribution of the Stock by the Underwriters, no
                  consent, approval, authorization or order of, or filing or
                  registration with, any such court or governmental agency or
                  body is required for the execution, delivery and performance
                  of this Agreement, the Power of Attorney or the Custody
                  Agreement by any Selling Shareholder and the consummation by
                  such Selling Shareholder of the transactions contemplated
                  hereby and thereby;

                           (ii) This Agreement has been duly authorized,
                  executed and delivered by or on behalf of each Selling
                  Shareholder;

                           (iii) A Power-of-Attorney and a Custody Agreement
                  have been duly authorized, executed and delivered by each
                  Selling Shareholder and constitute valid and binding
                  agreements of such Selling Shareholder, enforceable in
                  accordance with their respective terms, except as enforcement
                  may be limited by applicable bankruptcy, insolvency,
                  reorganization, moratorium, or other similar laws relating to
                  or affecting creditor's rights generally or by general
                  equitable principles; and

                           (iv) Each Selling Shareholder has full right, power
                  and authority to sell, transfer and deliver the shares of
                  Stock to be sold by such Selling Shareholder hereunder and
                  good and marketable title to such shares of Stock so sold,
                  free and clear of all voting trust arrangements, liens,

                  has been transferred to the Underwriters (who such counsel may
                  assume to be bona fide purchasers) who have purchased such
                  shares of Stock hereunder.

                           In rendering such opinion, such counsel may (i) state
                  that its opinion is limited to matters governed by the Federal
                  laws of the United States of America and the laws of the State
                  of Illinois and (ii) in rendering the opinions above, rely
                  upon a certificate of each Selling Shareholder (or
                  representations of such Selling Shareholder as set forth in
                  the Power of Attorney) in respect of matters of fact, provided
                  that such counsel shall furnish copies thereof to the
                  Representatives and state that it believes that both the
                  Underwriters and it are justified in relying upon such
                  certificate.

                  (f)      Snell & Wilmer shall have furnished to the 
         Representatives its written opinion, as special patent counsel to the
         Company, addressed to the Underwriters and dated the First Delivery
         Date, in form and substance reasonably satisfactory to the
         Representatives, to the effect that:

                           (i) To the best of such counsel's knowledge and other
                  than as set forth in the Prospectus, there are no pending or
                  threatened actions, suits, proceedings or claims of any third
                  party challenging the validity or scope of any United States
                  or foreign patent filed by the Company, and no actual or
                  threatened claim of infringement by the Company of a patent
                  held by a third party has been brought to such counsel's
                  attention by such third party; and

                           (ii) Such counsel has carefully examined the
                  Prospectus and no facts have come to such counsel's attention
                  that leads it to believe that the information contained under
                  the captions "Risk Factors - Intellectual Property Rights" and
                  "Business - Intellectual Property", insofar as it concerns
                  patent matters, as of the Effective Date, contained any untrue
                  statement of a material fact or omitted to state any material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading or that, as of the date of
                  such opinion, the information contained in such sections of
                  the Prospectus contains any untrue statement of a material
                  fact or omits to sate any material fact necessary in order to
                  make the statements therein, in light of the circumstances in
                  which they were made, not misleading.

                           In rendering such opinion, such counsel may (i) state
                  that its opinion is limited to matters governed by the Federal
                  laws of the United States of America and the laws of the State
                  of Arizona, and as to questions of fact upon representations
                  or certificates of officers of the Company and of government
                  officials, in which case their opinion is to state that they
                  are so relying and that they have no knowledge of any material
                  misstatement or inaccuracy in such opinions, representations
                  or certificates. Copies of any opinion, representation or
                  certificate so relied upon shall be delivered to the
                  Representatives and to the Representatives' counsel.

                  (g)      Baker & McKenzie shall have furnished to the 
         Representatives its written opinion, as counsel to SpeedFam Limited,
         addressed to the Underwriters and dated such Delivery Date, in form and
         substance reasonably satisfactory to the Representatives, to the effect
         that:

                           (i) SpeedFam Limited has been duly incorporated and
                  is validly existing as a corporation in good standing under
                  the laws of its jurisdiction of incorporation;

                           (ii) SpeedFam Limited has the corporate power to own,
                  lease and operate its properties and to conduct its business
                  as described in the Prospectus;

                           (iii) SpeedFam Limited is duly qualified to do
                  business as a foreign corporation and is in good standing in
                  each jurisdiction, if any, in which the ownership or leasing
                  of its properties or the conduct of its business requires such
                  qualification, except where the failure so to qualify would
                  not have a material adverse effect on the financial condition,
                  earnings, operations, business or business prospects of such
                  corporation; and


                                       15.
<PAGE>   16
                           (iv) With respect to SpeedFam Limited, the
                  performance of this Agreement and the consummation of the
                  transactions herein contemplated (other than performance of
                  the Company's indemnification and contribution obligations
                  hereunder, concerning which no opinion need be expressed) will
                  not, to such counsel's knowledge, result in the violation of
                  any foreign statue, rule or regulation.

                           Counsel rendering the foregoing opinion may rely as
                  to questions of fact upon representations or certificates of
                  officers of the Company and of government officials, in which
                  case their opinion is to state that they are so relying and
                  that they have no knowledge of any material misstatement or
                  inaccuracy in such representations or certificate. Copies of
                  any representation or certificate so relied upon shall be
                  delivered to you, as Representatives of the Underwriters, and
                  to Underwriters' Counsel.

                  (h)      Doser Amereller Noack shall have furnished to the 
         Representatives its written opinion, as counsel to SpeedFam GmbH,
         addressed to the Underwriters and dated such Delivery Date, in form and
         substance reasonably satisfactory to the Representatives, to the effect
         that:

                           (i) SpeedFam GmbH has been duly incorporated and is
                  validly existing as a limited liability corporation in good
                  standing under the laws of its jurisdiction of incorporation;

                           (ii) SpeedFam GmbH has the corporate power to own,
                  lease and operate its properties and to conduct its business
                  as described in the Prospectus;

                           (iii) SpeedFam GmbH is duly qualified to do business
                  as a foreign corporation and is in good standing in each
                  jurisdiction, if any, in which the ownership or leasing of its
                  properties or the conduct of its business requires such
                  qualification, except where the failure so to qualify would
                  not have a material adverse effect on the financial condition,
                  earnings, operations, business or business prospects of such
                  corporation; and

                           (iv) With respect to SpeedFam GmbH, the performance
                  of this Agreement and the consummation of the transactions
                  herein contemplated (other than performance of the Company's
                  indemnification and contribution obligations hereunder,
                  concerning which no opinion need be expressed) will not, to
                  such counsel's knowledge, result in the violation of any
                  foreign statue, rule or regulation.

                           Counsel rendering the foregoing opinion may rely as
                  to questions of fact upon representations or certificates of
                  officers of the Company and of government officials, in which
                  case their opinion is to state that they are so relying and

         Representatives a letter (the "bring-down letter") of such accountants,
         addressed to the Underwriters and dated such Delivery Date (i)
         confirming that they are independent public accountants within the
         meaning of the Securities Act and are in compliance with the applicable
         requirements relating to the qualification of accountants under Rule
         2-01 of Regulation S-X of the Commission, (ii) stating, as of the date

                           (i) The representations, warranties and agreements of
                  the Company in Section 1 are true and correct in all material
                  respects as of such Delivery Date; the Company has complied in
                  all material respects with all its agreements contained
                  herein; and the conditions set forth in Sections 9(a) and 9(o)
                  have been fulfilled; and

                           (ii) They have carefully examined the Registration
                  Statement and the Prospectus and, in their opinion (A) as of
                  the Effective Date, the Registration Statement and Prospectus
                  did not include any untrue statement of a material fact and
                  did not omit to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading, and (B) since the Effective Date no event has
                  occurred which should have been set forth in a supplement or
                  amendment to the Registration Statement or the Prospectus.

                  (o)      Each Selling Shareholder (or the Custodian or one or 
         more attorneys-in-fact on behalf of the Selling Shareholders) shall
         have furnished to the Representatives on the First Delivery Date a
         certificate, dated the First Delivery Date, signed by, or on behalf of,
         the Selling Shareholder (or the Custodian or one or more
         attorneys-in-fact) stating that the representations, warranties and
         agreements of


                                       18.
<PAGE>   19
         such Selling Shareholder contained in Section 2 are true and correct in
         all material respects as of the First Delivery Date and that such
         Selling Shareholder has complied in all material respects with all
         agreements contained herein to be performed by such Selling Shareholder
         at or prior to the First Delivery Date.

                  (p)      (i) Neither the Company nor any of its Subsidiaries 
         shall have sustained since November 30, 1996 any loss or interference
         with its business from fire, explosion, flood or other calamity,
         whether or not covered by insurance, or from any labor dispute or court
         or governmental action, order or decree, otherwise than as set forth or
         contemplated in the Prospectus or (ii) since such date, there shall not
         have been any change in the capital stock or long-term debt of the
         Company or any of its Subsidiaries (except as contemplated by Section
         1(v) hereof) or any change, or any development involving a prospective
         change, in or affecting the general affairs, management, financial
         position, shareholders' equity or results of operations of the Company
         and its Subsidiaries, otherwise than as set forth or contemplated in
         the Prospectus, the effect of which, in any such case described in
         clause (i) or (ii), is, in the judgment of the Representatives, so
         material and adverse as to make it impracticable or inadvisable to
         proceed with the public offering or the delivery of the Stock being
         delivered on such Delivery Date on the terms and in the manner
         contemplated in the Prospectus.

                  (q)      Subsequent to the execution and delivery of this 
         Agreement there shall not have occurred any of the following: (i)
         trading in securities generally on the New York Stock Exchange or the
         American Stock Exchange or in the over-the-counter market, or trading
         in any securities of the Company on any exchange or in the
         over-the-counter market, shall have been suspended or minimum prices
         shall have been established on any such exchange or such market by the
         Commission, by such exchange or by any other regulatory body or
         governmental authority having jurisdiction, (ii) a banking moratorium
         shall have been declared by Federal or state authorities, (iii) the
         United States shall have become engaged in hostilities, there shall
         have been an escalation in hostilities involving the United States or
         there shall have been a declaration of a national emergency or war by
         the United States or (iv) there shall have occurred such a material
         adverse change in general economic, political or financial conditions
         (or the effect of international conditions on the financial markets in
         the United States shall be such) as to make it, in the judgment of a
         majority in interest of the several Underwriters, impracticable or
         inadvisable to proceed with the public offering or delivery of the
         Stock being delivered on such Delivery Date on the terms and in the
         manner contemplated in the Prospectus.

                  (r)      The Nasdaq National Market System shall have approved
         the Stock for listing subject only to official notice of issuance and
         evidence of satisfactory distribution.

                           All opinions, letters, evidence and certificates
         mentioned above or elsewhere in this Agreement shall be deemed to be in
         compliance with the provisions hereof only if they are in form and
         substance reasonably satisfactory to counsel for the Underwriters.

         10.      Indemnification and Contribution.

                  (a) The Company shall indemnify and hold harmless each
         Underwriter, its officers and employees and each person, if any, who
         controls any Underwriter within the meaning of the Securities Act and
         the Exchange Act, from and against any loss, claim, damage or
         liability, joint or several, or any action in respect thereof
         (including, but not limited to, any loss, claim, damage, liability or
         action relating to purchases and sales of Stock), to which that
         Underwriter, officer, employee or controlling person may become
         subject, under the Securities Act, the Exchange Act or otherwise,
         insofar as such loss, claim, damage, liability or action arises out of,
         or is based upon, (i) any untrue statement or alleged untrue statement
         of a material fact contained (A) in any Preliminary Prospectus, the
         Registration Statement or the Prospectus or in any amendment or
         supplement thereto or (B) in any blue sky application or other document
         prepared or executed by the Company (or based upon any written
         information furnished by the Company) specifically for the purpose of
         qualifying any or all of the Stock under the securities laws of any
         state or other jurisdiction (any such application, document or


                                       19.
<PAGE>   20
         information being hereinafter called a "Blue Sky Application"), (ii)
         the omission or alleged omission to state in any Preliminary
         Prospectus, the Registration Statement or the Prospectus, or in any
         amendment or supplement thereto, or in any Blue Sky Application any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, or (iii) any act or failure to act
         or any alleged act or failure to act by any Underwriter in connection
         with, or relating in any manner to, the Stock or the offering
         contemplated hereby, and which is included as part of or referred to in
         any loss, claim, damage, liability or action arising out of or based
         upon matters covered by clause (i) or (ii) above (provided that the
         Company shall not be liable under this clause (iii) to the extent that
         it is determined in a final judgment by a court of competent
         jurisdiction that such loss, claim, damage, liability or action
         resulted directly from any such acts or failures to act undertaken or
         omitted to be taken by such Underwriter through its gross negligence or
         willful misconduct) and shall reimburse each Underwriter and each such
         officer, employee or controlling person promptly upon demand for any
         legal or other expenses reasonably incurred by that Underwriter,
         officer, employee or controlling person in connection with
         investigating or defending or preparing to defend against any such
         loss, claim, damage, liability or action as such expenses are incurred;
         provided, however, that the Company shall not be liable in any such
         case to the extent that any such loss, claim, damage, liability or
         action arises out of, or is based upon, any untrue statement or alleged
         untrue statement or omission or alleged omission made in any
         Preliminary Prospectus, the Registration Statement or the Prospectus,
         or in any such amendment or supplement, or in any Blue Sky Application,
         in reliance upon and in conformity with written information concerning
         such Underwriter furnished to the Company through the Representatives
         by or on behalf of any Underwriter specifically for inclusion therein
         or if such statement or omission was contained or made in any
         preliminary prospectus and corrected in the Prospectus and (1) any such
         loss, claim, damage or liability suffered or incurred by an Underwriter
         (or any person who controls any Underwriter) resulted from an action,
         claim or suit by any person who purchased Stock which are the subject
         thereof from such Underwriter in the offering and (2) such Underwriter
         failed to deliver or provide a copy of the Prospectus to such person at
         or prior to the confirmation of the sale of such Stock in any case
         where such delivery is required by the Securities Act. The foregoing
         indemnity agreement is in addition to any liability which the Company
         may otherwise have to any Underwriter or to any officer, employee or
         controlling person of that Underwriter.

                  (b)      The Key Selling Shareholder shall indemnify and hold
         harmless each Underwriter, its officers and employees, and each person,
         if any, who controls any Underwriter within the meaning of the
         Securities Act and the Exchange Act, from and against any loss, claim,
         damage or liability, joint or several, or any action in respect thereof
         (including, but not limited to, any loss, claim, damage, liability or
         action relating to purchases and sales of Stock), to which that
         Underwriter, officer, employee or controlling person may become
         subject, under the Securities Act or the Exchange Act or otherwise,
         insofar as such loss, claim, damage, liability or action arises out of,
         or is based upon, (i) any untrue statement or alleged untrue statement
         of a material fact contained in any Preliminary Prospectus, the
         Registration Statement or the Prospectus or in any amendment or
         supplement thereto, but only with reference to information relating to
         the Key Selling Shareholder furnished in writing by or on behalf of the
         Key Selling Shareholder expressly for use in the Registration Statement
         or Prospectus, or (ii) the omission or alleged omission to state in any
         Preliminary Prospectus, Registration Statement or the Prospectus, or in
         any amendment or supplement thereto, any material fact required to be
         stated therein or necessary to make the statements therein not
         misleading, but only with reference to information relating to the Key
         Selling Shareholder furnished in writing by or on behalf of the Key
         Selling Shareholder expressly for use in the Registration Statement or
         Prospectus, and shall reimburse each Underwriter, its officers and
         employees and each such controlling person for any legal or other
         expenses reasonably incurred by that Underwriter, its officers and
         employees or controlling person in connection with investigating or
         defending or preparing to defend against any such loss, claim, damage,
         liability or action as such expenses are incurred; provided, however,
         that the Key Selling Shareholders shall in no event be liable for
         losses or claims exceeding the proceeds received by the Key Selling
         Shareholder from the sale of their respective Stock upon the
         consummation of the sale contemplated hereunder. The foregoing
         indemnity agreement is in addition to


                                       20.
<PAGE>   21
         any liability which the Key Selling Shareholders may otherwise have to
         any Underwriter or any officer, employee or controlling person of that
         Underwriter.

                  (c)      Each Underwriter, severally and not jointly, shall 
         indemnify and hold harmless the Company, its officers and employees,
         each of its directors and each person, if any, who controls the Company
         within the meaning of the Securities Act and the Exchange Act, from and
         against any loss, claim, damage or liability, joint or several, or any
         action in respect thereof, to which the Company or any such director,
         officer or controlling person may become subject, under the Securities
         Act, the Exchange Act or otherwise, insofar as such loss, claim,
         damage, liability or action arises out of, or is based upon, (i) any
         untrue statement or alleged untrue statement of a material fact
         contained (A) in any Preliminary Prospectus, the Registration Statement
         or the Prospectus or in any amendment or supplement thereto, or (B) in
         any Blue Sky Application or (ii) the omission or alleged omission to
         state in any Preliminary Prospectus, the Registration Statement or the
         Prospectus, or in any amendment or supplement thereto, or in any Blue
         Sky Application any material fact required to be stated therein or
         necessary to make the statements therein not misleading, but in each
         case only to the extent that the untrue statement or alleged untrue
         statement or omission or alleged omission was made in reliance upon and
         in conformity with written information concerning such Underwriter
         furnished to the Company through the Representatives by or on behalf of
         that Underwriter specifically for inclusion therein, and shall
         reimburse the Company and any such director, officer or controlling
         person for any legal or other expenses reasonably incurred by the
         Company or any such director, officer or controlling person in
         connection with investigating or defending or preparing to defend
         against any such loss, claim, damage, liability or action as such
         expenses are incurred. The foregoing indemnity agreement is in addition
         to any liability which any Underwriter may otherwise have to the
         Company or any such director, officer, employee or controlling person.

                  (d)      Promptly after receipt by an indemnified party under 
         this Section 10 of notice of any claim or the commencement of any
         action, the indemnified party shall, if a claim in respect thereof is
         to be made against the indemnifying party under this Section 10, notify
         the indemnifying party in writing of the claim or the commencement of
         that action; provided, however, that the failure to notify the
         indemnifying party shall not relieve it from any liability which it may
         have under this Section 10 except to the extent it has been materially
         prejudiced by such failure and, provided further, that the failure to
         notify the indemnifying party shall not relieve it from any liability
         which it may have to an indemnified party otherwise than under this
         Section 10. If any such claim or action shall be brought against an
         indemnified party, and it shall notify the indemnifying party thereof,
         the indemnifying party shall be entitled to participate therein and, to
         the extent that it wishes, jointly with any other similarly notified
         indemnifying party, to assume the defense thereof with counsel
         reasonably satisfactory to the indemnified party. After notice from the
         indemnifying party to the indemnified party of its election to assume
         the defense of such claim or action, the indemnifying party shall not
         be liable to the indemnified party under this Section 10 for any legal
         or other expenses subsequently incurred by the indemnified party in
         connection with the defense thereof other than reasonable costs of
         investigation; provided, however, that the Representatives shall have
         the right to employ counsel to represent jointly the Representatives
         and those other Underwriters and their respective officers, employees
         and controlling persons who may be subject to liability arising out of
         any claim in respect of which indemnity may be sought by the
         Underwriters against the Company or any Selling Shareholder under this
         Section 10 if, in the reasonable judgment of the Representatives, it is
         advisable for the Representatives and those Underwriters, officers,
         employees and controlling persons to be jointly represented by separate
         counsel, and in that event the fees and expenses of such separate
         counsel shall be paid by the Company or the Selling Shareholders. No
         indemnifying party shall (i) without the prior written consent of the
         indemnified parties (which consent shall not be unreasonably withheld),
         settle or compromise or consent to the entry of any judgment with
         respect to any pending or threatened claim, action, suit or proceeding
         in respect of which indemnification or contribution may be sought
         hereunder (whether or not the indemnified parties are actual or
         potential parties to such claim or action) unless such settlement,
         compromise or consent includes an unconditional release of each
         indemnified party from all liability arising out of such claim, action,
         suit or proceeding, or (ii) be liable for any settlement of any such


                                       21.
<PAGE>   22
         action effected without its written consent (which consent shall not be
         unreasonably withheld), but if settled with the consent of the
         indemnifying party or if there be a final judgment of the plaintiff in
         any such action, the indemnifying party agrees to indemnify and hold
         harmless any indemnified party from and against any loss or liability
         by reason of such settlement or judgment.

                  (e)      If the indemnification provided for in this Section 
         10 shall for any reason be unavailable to or insufficient to hold
         harmless an indemnified party under Section 10(a), 10(b) or 10(c) in
         respect of any loss, claim, damage or liability, or any action in
         respect thereof, referred to therein, then each indemnifying party
         shall, in lieu of indemnifying such indemnified party, contribute to
         the amount paid or payable by such indemnified party as a result of
         such loss, claim, damage or liability, or action in respect thereof,
         (i) in such proportion as shall be appropriate to reflect the relative
         benefits received by the Company, the Selling Shareholders and the
         Underwriters, respectively, from the offering of the Stock or (ii) if
         the allocation provided by clause (i) above is not permitted by
         applicable law, in such proportion as is appropriate to reflect not
         only the relative benefits referred to in clause (i) above but also the
         relative fault of the Company, the Selling Shareholders and the
         Underwriters respectively with respect to the statements or omissions
         which resulted in such loss, claim, damage or liability, or action in
         respect thereof, as well as any other relevant equitable
         considerations. The relative benefits received by the Company, the
         Selling Shareholders and the Underwriters, respectively with respect to
         such offering shall be deemed to be in the same proportion as the total
         net proceeds from the offering of the Stock purchased under this
         Agreement (before deducting expenses) received by the Company, the
         Selling Shareholders, respectively and the total underwriting discounts
         and commissions received by the Underwriters with respect to the shares
         of the Stock purchased under this Agreement, on the other, bear to the
         total gross proceeds from the offering of the shares of the Stock under
         this Agreement, in each case as set forth in the table on the cover
         page of the Prospectus. The relative fault shall be determined by
         reference to whether the untrue or alleged untrue statement of a
         material fact or omission or alleged omission to state a material fact
         relates to information supplied by the Company, the Selling
         Shareholders or the Underwriters, the intent of the parties and their
         relative knowledge, access to information and opportunity to correct or
         prevent such statement or omission. The Company, the Selling
         Shareholders and the Underwriters agree that it would not be just and
         equitable if contributions pursuant to this Section were to be
         determined by pro rata allocation (even if the Underwriters were
         treated as one entity for such purpose) or by any other method of
         allocation which does not take into account the equitable
         considerations referred to herein. The amount paid or payable by an
         indemnified party as a result of the loss, claim, damage or liability,
         or action in respect thereof, referred to above in this Section shall
         be deemed to include, for purposes of this Section 10(e), any legal or
         other expenses reasonably incurred by such indemnified party in
         connection with investigating or defending any such action or claim.
         Notwithstanding the provisions of this Section 10(e), no Underwriter
         shall be required to contribute any amount in excess of the amount by
         which the total price at which the Stock underwritten by it and
         distributed to the public was offered to the public exceeds the amount
         of any damages which such Underwriter has otherwise paid or become
         liable to pay by reason of any untrue or alleged untrue statement or
         omission or alleged omission and no Selling Shareholder shall be
         required to contribute any amount in excess of the amount by which the
         proceeds received by such Selling Shareholder from the sale of the
         shares of Stock hereunder exceeds the amount of any damages which such
         Selling Shareholder has otherwise been required to pay by reason of
         such untrue or alleged untrue statement or omission or alleged
         omission. No person guilty of fraudulent misrepresentation (within the
         meaning of Section 11(f) of the Securities Act or the Exchange Act)
         shall be entitled to contribution from any person who was not guilty of
         such fraudulent misrepresentation. The Underwriters' obligations to
         contribute as provided in this Section 10(e) are several in proportion
         to their respective underwriting obligations and not joint.

                  (f)      The Underwriters severally confirm and the Company 
         acknowledges that the statements with respect to the public offering of
         the Stock by the Underwriters set forth on the cover page of, the
         legends concerning over-allotments and passive market making on the
         inside front cover page of and the section "Underwriting" in, the
         Prospectus are correct and constitute the only information


                                       22.
<PAGE>   23
         concerning such Underwriters furnished in writing to the Company by or
         on behalf of the Underwriters specifically for inclusion in the
         Registration Statement and the Prospectus.

         11.      Defaulting Underwriters. If, on either Delivery Date, any 
Underwriter defaults in the performance of its obligations under this Agreement,
the remaining non-defaulting Underwriters shall be obligated to purchase the
Stock which the defaulting Underwriter agreed but failed to purchase on such
Delivery Date in the respective proportions which the number of shares of the
Firm Stock set opposite the name of each remaining non-defaulting Underwriter in
Schedule 1 hereto bears to the total number of shares of the Firm Stock set
opposite the names of all the remaining non-defaulting Underwriters in Schedule
1 hereto; provided, however, that the remaining non-defaulting Underwriters
shall not be obligated to purchase any of the Stock on such Delivery Date if the
total number of shares of the Stock which the defaulting Underwriter or
Underwriters agreed but failed to purchase on such date exceeds 9.9% of the
total number of shares of the Stock to be purchased on such Delivery Date, and
any remaining non-defaulting Underwriter shall not be obligated to purchase more
than 110% of the number of shares of the Stock which it agreed to purchase on
such Delivery Date pursuant to the terms of Section 3. If the foregoing maximums
are exceeded, the remaining non-defaulting Underwriters, or those other
underwriters satisfactory to the Representatives who so agree, shall have the
right, but shall not be obligated, to purchase, in such proportion as may be
agreed upon among them, all the Stock to be purchased on such Delivery Date. If
the remaining Underwriters or other underwriters satisfactory to the
Representatives do not elect to purchase the shares which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such Delivery Date,
this Agreement (or, with respect to the Second Delivery Date, the obligation of
the Underwriters to purchase, and of the Company to sell, the Option Stock)
shall terminate without liability on the part of any non-defaulting Underwriter
or the Company or the Selling Shareholders, except that the Company will
continue to be liable for the payment of expenses to the extent set forth in
Sections 8 and 13. As used in this Agreement, the term "Underwriter" includes,
for all purposes of this Agreement unless the context requires otherwise, any
party not listed in Schedule 1 hereto who, pursuant to this Section 11,
purchases Firm Stock which a defaulting Underwriter agreed but failed to
purchase.

                  Nothing contained herein shall relieve a defaulting
Underwriter of any liability it may have to the Company and the Selling
Shareholders for damages caused by its default. If other underwriters are
obligated or agree to purchase the Stock of a defaulting or withdrawing
Underwriter, either the Representatives or the Company may postpone the Delivery
Date for up to seven full business days in order to effect any changes that in
the opinion of counsel for the Company or counsel for the Underwriters may be
necessary in the Registration Statement, the Prospectus or in any other document
or arrangement.

         12.      Termination. The obligations of the Underwriters hereunder may
be terminated by the Representatives by notice given to and received by the
Company and the Selling Shareholders prior to delivery of and payment for the
Firm Stock if, prior to that time, any of the events described in Sections 9(o)
or 9(p), shall have occurred or if the Underwriters shall decline to purchase
the Stock for any reason permitted under this Agreement.

         13.      Reimbursement of Underwriters' Expenses. If (a) the Company or
any Selling Shareholder shall fail to tender the Stock for delivery to the
Underwriters by reason of any failure, refusal or inability on the part of the
Company or the Selling Shareholder(s) to perform any agreement on its part to be
performed, or because any other condition of the Underwriters' obligations
hereunder required to be fulfilled by the Company or the Selling Shareholder(s)
is not fulfilled, the Company will reimburse the Underwriters for all reasonable
out-of-pocket expenses (including fees and disbursements of counsel) incurred by
the Underwriters in connection with this Agreement and the proposed purchase of
the Stock, and upon demand the Company shall pay the full amount thereof to the
Representative(s). If this Agreement is terminated pursuant to Section 9(o) or
9(p) or Section 11 by reason of the default of one or more Underwriters, neither
the Company nor any Selling Shareholder shall be obligated to reimburse any
defaulting Underwriter on account of those expenses.

provided, however, that any notice to an Underwriter pursuant to Section 10(d)

consent, notice or agreement given or made on behalf of the Underwriters by
Lehman Brothers Inc. on behalf of the Representatives and the Company and the
Underwriters shall be entitled to act and rely upon any request, consent, notice
or agreement given or made on behalf of the Selling Shareholders by the

         15.      Persons Entitled to Benefit of Agreement. This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Company, the
Selling Shareholders and their respective personal representatives and
successors. This Agreement and the terms and provisions hereof are for the sole

persons, if any, who control any Underwriter within the meaning of Section 15 of
the Securities Act and the Exchange Act and (B) the indemnity agreement of the
Underwriters contained in Section 10(c) of this Agreement shall be deemed to be
for the benefit of directors of the Company, officers and Selling Shareholders
of the Company who have signed the Registration Statement and any person
controlling the Company within the meaning of Section 15 of the Securities Act
and the Exchange Act. Nothing in this Agreement is intended or shall be
construed to give any person, other than the persons referred to in this Section
15, any legal or equitable right, remedy or claim under or in respect of this
Agreement or any provision contained herein.

         16.      Survival. The respective indemnities, representations, 
warranties and agreements of the Company, the Selling Shareholders and the
Underwriters contained in this Agreement or made by or on behalf on them,
respectively, pursuant to this Agreement, shall survive the delivery of and
payment for the Stock and shall remain in full force and effect, regardless of
any investigation made by or on behalf of any of them or any person controlling
any of them.

         17.      Definition of the Term "Business Day." For purposes of this 
Agreement, "business day" means any day on which the New York Stock Exchange,

SpeedFam International, Inc.
305 North 54th Street
Chandler, Arizona  85226

Ladies/Gentlemen:

      You have requested our opinion as counsel for SpeedFam International,
Inc., an Illinois corporation (the "Company"), in connection with the
registration under the Securities Act of 1933, as amended, and the Rules and
Regulations promulgated thereunder, and the public offering as contemplated
thereby of 2,170,000 shares of the Company's common stock, no par value
(together with up to 325,500 shares of such stock to cover over-allotments, the
"Common Stock"). Of such shares of Common Stock, up to 170,000 are currently
outstanding and are proposed to be sold by certain shareholders of the Company
(the "Selling Shareholders").

      We have examined the Company's Registration Statement on Form S-3 to be
filed with the Securities and Exchange Commission on September 17, 1997 (the
"Registration Statement"). We have further examined the originals or certified,

appropriate as the basis for the opinion hereinafter expressed. In connection
with this opinion, we have examined the originals, or certified, conformed or

                  SECTION 2 AMOUNTS AND TERMS OF OBLIGATIONS

                  2.1 Revolving Loans.

                           (a) Prior to the Termination Date and so long as no
         Default has occurred, the Banks agree separately and independently (and
         not jointly) on the terms and conditions set forth in this Agreement to
         extend to the Company Revolving Loans from time to time in amounts not
         to exceed in the aggregate at any one time outstanding the Revolving
         Loan Commitment less the face amount of all outstanding Letters of
         Credit. Revolving Loans shall be made by the Banks Pro Rata. Subject to
         the terms of this Agreement, the Company may borrow, repay (in whole or
         in part) and reborrow the Revolving Loans prior to the Termination
         Date. The Revolving Loans made by each Bank shall be evidenced by their
         respective Revolving Credit Notes.

                           (b) (i) From the date of the first Revolving Loan and
         until all Revolving Loans are paid in full, the Company shall pay all
         accrued and unpaid interest on the Revolving Loans on the first day of
         each month. Prior to an Event of Default, interest shall accrue on the
         aggregate unpaid principal amount from time to time outstanding under
         the Revolving Credit Notes at a rate per annum equal to (a) the
         applicable LIBOR Rate on each LIBOR Rate Loan , and (b) the Prime Rate
         on Revolving Loans which are not LIBOR Rate Loans. Interest shall be
         computed and adjusted daily based on the actual number of days elapsed
         in a year of 360 days. All outstanding unpaid principal and accrued
         interest on the Revolving Loans shall be due and payable on the
         Termination Date for the Revolving Loans.

                           (ii) The initial LIBOR Interest Margin shall be 0.50%
         per annum. If, at the end of any fiscal quarter after the date hereof,
         the ratio of Funded Debt, as of the end of each fiscal quarter, to Cash
         Flow, for the four quarters then ended, as shown on the Company's
         financial statements for such quarters delivered to the Banks pursuant
         to Sections 5.3(a) or (b), is less than 1.0 : 1.0, then the LIBOR
         Interest Margin for all LIBOR Rate Loans shall be 0.50% per annum,
         effective on the date of receipt of such financial statements by the
         Banks. If, at the end of any fiscal quarter after the date hereof, the
         ratio of Funded Debt, as of the end of each fiscal quarter, to Cash
         Flow, for the four quarters then ended, is equal to or greater than 2.0
         : 1.0, as shown on the Company's financial statements for such quarters
         delivered to the Banks pursuant to Sections 5.3(a) or (b), then the
         LIBOR Interest Margin for all LIBOR Rate Loans shall be equal to 1.00%
         per annum, effective on the date of receipt of such financial
         statements by the Banks. If, at the end of any fiscal quarter after the
         date hereof, the ratio of Funded Debt, as of the end

                                       11
<PAGE>   17
         of each fiscal quarter, to Cash Flow, for the four quarters then ended,
         is equal to or greater than 1.0 : 1.0 but less than 2.0 : 1.0, as shown
         on the Company's financial statements for such quarters delivered to
         the Banks pursuant to Sections 5.3(a) or (b), then the LIBOR Interest
         Margin for all LIBOR Rate Loans shall be equal to 0.75% per annum,
         effective on the date of receipt of such financial statements by the
         Banks. The Agent shall promptly notify the Banks of any applicable
         reduction or increase in the LIBOR Interest Margin.

                           (c) The Company may obtain Revolving Loans by making
         a request therefor to the Agent, orally or in writing. Such request
         shall specify a Business Day prior to the Termination Date on which
         such Revolving Loans are to be made (the "Borrowing Date"), shall be
         received by the Agent by 12:00 Noon (Milwaukee time) three Business
         Days before the Borrowing Date in the case of LIBOR Rate Loans or
         otherwise by 12:00 Noon (Milwaukee time) of the Borrowing Date, and
         shall specify the amount of the Revolving Loans requested, whether the
         Revolving Loans are to be LIBOR Rate Loans and, if so, the requested
         Loan Period; provided, however, that within three days after any oral
         request for a Revolving Loan which is a LIBOR Rate Loan, the Agent
         shall receive from the Company a written confirmation in form
         acceptable to the Agent confirming the Company's LIBOR Rate Loan
         request, and the Banks' obligation to make further Revolving Loans
         hereunder shall be suspended until such confirmation has been received
         by the Agent. In the event of any inconsistency between the telephonic
         notice and the written confirmation thereof, the telephonic notice
         shall control. The Company shall be obligated to repay all Revolving
         Loans notwithstanding the failure of the Agent to receive written
         confirmation, and notwithstanding the fact that the person requesting
         the Revolving Loan was not in fact authorized to do so. No Revolving
         Loan request shall be modified, altered or amended without the prior
         written consent of the Agent. Each Revolving Loan shall be in the
         principal amount of the lesser of (i) $100,000 or a multiple thereof or
         (ii) the Maximum Available Commitment; provided, however, that the
         Company may not request LIBOR Rate Loans in an amount less than
         $500,000 per request. The Agent shall promptly inform each Bank of each
         Revolving Loan request. Each Bank shall make available to the Agent at
         its principal office in Milwaukee, Wisconsin, in immediately available
         funds and not later than 3:00 p.m. Milwaukee time on the Borrowing
         Date, the amount of such Bank's Pro Rata share of such Revolving Loans.
         Upon receipt by the Agent of the amount of a Bank's Revolving Loan and
         fulfillment of the conditions specified in Section 4.2, the Agent shall
         promptly deposit the amount of such Revolving Loan in the general
         deposit account of the Company maintained at the Agent.

                           (d) Revolving Loans which are not LIBOR Rate Loans
         may be converted (in amounts not less than $500,000 and additional
         increments of $100,000) into LIBOR Rate Loans by notice from the
         Company to the Agent meeting the requirements of Section 2.1(c). At the
         end of each respective Loan Period, LIBOR Rate Loans shall become
         Revolving Loans which are not LIBOR Rate Loans unless and until the
         Company converts such Revolving Loans to LIBOR Rate Loans.

                           (e) The Company may request LIBOR Rate Loans only so
         long as the outstanding LIBOR Rate Loans bear no more than ten
         different LIBOR Rates. The Agent may require any LIBOR Rate Loans to be
         repaid prior to the Termination Date and may refuse to make LIBOR Rate
         Loans in the event the Agent determines that (i) maintenance of the
         LIBOR Rate Loans would violate any applicable Requirements of Law, (ii)
         the interest rates on LIBOR Rate Loans do not accurately reflect the
         cost of making such Revolving Loans, or (iii) deposits in the amount of
         any LIBOR Rate Loan are not available to the Agent in the London
         eurodollar interbank market.

                           (f) In the event any Bank shall incur any loss, cost,
         expense or premium (including, without limitation, any loss of profit
         or loss, cost, expense or premium incurred by reason of the liquidation
         or reemployment of deposits or other funds acquired or contracted to be
         acquired by such Bank to fund or maintain LIBOR Rate Loans or the
         relending or reinvesting of such deposits or other funds or amounts
         paid or prepaid to such Bank), as a result of:

                                    (i) any payment of any LIBOR Rate Loans on a
                  date other than the last day of the then applicable Loan
                  Period for any reason, whether before or after Default, and
                  whether or not such payment is required by any provisions of
                  this Agreement; or

                                    (ii) any failure by the Company to create,
                  borrow, continue or effect by conversion any LIBOR Rate Loans
                  on the date specified in a notice given pursuant to this
                  Agreement;

         then upon the demand of such Bank, the Company shall pay to such Bank
         such amount as will reimburse such Bank for such loss, cost, expense or
         premium. If a Bank requests such a reimbursement it shall provide the
         Company with a certificate setting forth the computation of the loss,
         cost, expense or premium giving rise to the request for reimbursement
         in reasonable detail and such certificate shall be deemed prima facie
         correct.

                           (g) The Company may, upon one Business Day's prior
         written notice to the Agent, permanently reduce the aggregate

                                       13
<PAGE>   19
         amount of the Revolving Loan Commitment; provided that no such
         reduction shall reduce the aggregate amount of the Revolving Loan
         Commitment to an amount less than the aggregate unpaid principal
         balance of the Revolving Credit Notes and any outstanding Letters of
         Credit on the effective date of such reduction. Each reduction in the
         Revolving Loan Commitment shall be in a minimum amount of $100,000 and
         in integral multiples of $100,000 above such minimum.

                  2.2 Letters of Credit. Prior to the Termination Date and so
long as no Default has occurred, the Agent may from time to time, in the sole
and absolute discretion of the Required Banks, issue Letters of Credit requested
by the Company. The Company shall execute and deliver to the Agent the Agent's
standard forms of agreements for irrevocable or standby documentary Letters of
Credit evidencing the Company's reimbursement obligation to the Agent and the
Banks. All outstanding Letters of Credit shall expire not later than the earlier
of one year from the date of issuance or the Termination Date. In no event shall
the aggregate amount of outstanding Letters of Credit exceed $10,000,000. Drafts
drawn upon Letters of Credit shall be treated as Revolving Loans and shall bear
interest at the rate of interest payable upon the Revolving Loans which are not
LIBOR Rate Loans.

                  2.3 Funding Procedures. Unless the Company or a Bank, as the
case may be, notifies the Agent prior to the date on which it is scheduled to
make payment to the Agent, of (i) in the case of a Bank, the proceeds of a
Revolving Loan or draw under a Letter of Credit as required hereunder or (ii) in
the case of the Company, a payment of principal, interest, fees or charges to
the Agent for the account of the Banks, that it does not intend to make such
payment, the Agent may assume that such payment has been made. The Agent may,
but shall not be obligated to, make the amount of such payment available to the
intended recipient in reliance upon such assumption. If such Bank or the
Company, as the case may be, has not in fact made such payment to the Agent, the
recipient of such payment shall, on demand by the Agent, repay to the Agent the
amount so made available together with interest thereon in respect of each day
during the period commencing on the date such amount was so made available by
the Agent until the date the Agent recovers such amount at a rate per annum
equal to (a) in the case of payment by a Bank, the federal funds rate for each
of the first three business days after the date of funding (as determined by the
Agent) and thereafter at the interest rate applicable to the relevant
Obligation, or (b) in the case of payment by the Company, the interest rate
applicable to the relevant Obligation. A statement of the Agent submitted to the
Company or any Bank with respect to any amounts owing under this Section 2.3
shall be conclusive, in the absence of manifest error. The failure of one of the
Banks to make any Revolving Loan or loan respecting a draw under a Letter of
Credit as required hereunder shall not relieve any other Bank of its obligation
to lend its Pro Rata share of such

                                       14
<PAGE>   20
Revolving Loan or Letter of Credit, hereunder, and in no event shall such other
Banks or the Agent be liable in any way whatsoever to the Company for such
failure of any Bank to make any Revolving Loan or loan respecting a Letter of
Credit hereunder.

                  2.4 Interest After Default. After an Event of Default, each of
the Obligations shall bear interest at the rate of 2% per annum in excess of the
applicable rates set forth herein; provided, that in the case of a LIBOR Rate
Loan the maturity of which is accelerated, such LIBOR Rate Loan shall bear
interest for the remainder of the applicable Loan Period at a rate equal to 2%
plus the higher of the rate on the LIBOR Rate Loan or the rate on Revolving
Loans which are not LIBOR Rate Loans. In no event shall the interest rate on the
Obligations exceed the highest rate permitted by law.

                  2.5 Loan Account. The Agent will enter as a debit to the Loan
Account the aggregate principal amount of each Obligation as disbursed or issued
from time to time by the Agent. The Agent shall also record in the Loan Account,
in accordance with the Agent's customary accounting practices: accrued interest
and all other charges, expenses and other items properly chargeable to the
Company hereunder or under the Related Documents; all payments made by the
Company with respect to the Obligations, if any; and all other appropriate
debits and credits. The debit balance of the Loan Account shall reflect the
amount of the Obligations and other appropriate charges hereunder. Not more
frequently than once each month, the Agent shall render a statement of account
of the Loan Account including, with respect to Revolving Loans, a statement of
the outstanding principal balance, Loan Period and applicable LIBOR Rate for
each LIBOR Rate Loan, which statement shall be considered correct and accepted
by the Company and conclusively binding upon the Company unless it notifies the
Agent to the contrary within 30 days of the mailing of such statement by the
Agent to the Company; provided, however, that the failure of the Agent to record
any of the foregoing items in the Loan Account shall not limit or otherwise
affect the Company's obligation to repay the Obligations.

                  2.6 Payments. Whenever any payment to be made hereunder shall
be stated to be due on a day which is not a Business Day, such payment may be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest on the
Obligations. Payments made by the Company to the Agent after 1:00 p.m. Milwaukee
time shall be credited on the next Business Day. The Agent may debit to the
depository accounts maintained by the Company with the Agent all payments on the
Obligations when due without prior notice to or consent of the Company, provided
that upon any such debit, the Agent will notify the Company of such debit
promptly.

                  2.7 Prepayments.

                           (a) Optional Prepayments. The Company may at its
         option, at any time and from time to time, prepay the Obligations, in
         whole or in part. Partial prepayments shall be in the principal amount
         of $100,000 or a multiple thereof, together with accrued interest to
         the date of prepayment on the amount prepaid. There shall be no
         prepayment premium or penalty except as provided in Section 2.1(f).

                           (b) Mandatory Prepayment. At any time that the
         aggregate principal amount of Revolving Loans outstanding and face
         amount of Letters of Credit outstanding hereunder exceeds the Revolving
         Loan Commitment, the Company shall immediately pay the amount of such
         excess in immediately available funds, together with interest accrued
         on the amount of the payment.

                  2.8 Effect of Regulatory Change. In the event of a Regulatory
Change deemed by any Bank in good faith to be material, the Company shall pay to
such Bank (within ten days after notice by such Bank to the Company of such
Regulatory Change such notice which shall include a reasonably detailed
description of such Regulatory Change) such amounts as such Bank deems
reasonably necessary to compensate such Bank for the increase in the cost of
making or maintaining the Obligations or the reduction in the rate of return to
such Bank on the Obligations resulting from the Regulatory Change.

                  2.9 No Obligation to Extend or Forbear. The Company
acknowledges and agrees that the Agent and the Banks (a) upon execution hereof,
have no duty or obligation of any kind to, and have made no representations of
any kind or nature that the Banks will, extend credit or any other kind of
financial accommodations to the Company after the Termination Date, or forbear
at any time from the exercise of any of their rights or remedies under this
Agreement, the Related Documents and applicable law, and (b) may at any time, in
their sole and absolute discretion, exercise whatever rights and remedies the
Agent and the Banks may have under this Agreement, the Related Documents and
applicable law. All Obligations shall be due in full on the Termination Date
without further demand.

                  SECTION 3 REPRESENTATIONS AND WARRANTIES

                  In order to induce the Banks to enter into this Agreement and
make and incur the Obligations as herein provided, the Company hereby represents
and warrants to the Agent and the Banks as follows:

                  3.1 Organization, Qualification and Subsidiaries. The Company
and the Guarantor each is a corporation duly organized and validly existing and
in good standing under the laws of the state

                                       16
<PAGE>   22
or jurisdiction of its incorporation. The Company and the Guarantor each has the
corporate power and authority and all necessary licenses, permits and franchises
to borrow hereunder and to own its assets and conduct its business as presently
conducted. The Company and the Guarantor each is duly licensed or qualified to
do business and is in good standing in all jurisdictions in which the Company
and the Guarantor each has substantial property or business operations, and to
the best of the Company's knowledge, the Company and the Guarantor each has no
material liabilities as a result of a failure to qualify to do business as a
foreign corporation in any jurisdiction. All of the issued and outstanding
capital stock of the Company and the Guarantor has been validly issued and is
fully paid and non-assessable. Except as set forth on SCHEDULE 2, (a) the
Company has no Subsidiaries, (b) the Company does not own, directly or
indirectly, more than 1% of the total outstanding shares of any class of capital
stock of any other Person, and (c) there are no outstanding options, warrants or
other rights to subscribe for or purchase from the Company any capital stock of
the Company or securities convertible into or exchangeable for capital stock of
the Company.

                  3.2 Financial Statements. The Company has furnished to the
Banks year-end consolidated and consolidating financial statements for the
Company for its fiscal years ended May 31, 1997 and May 31, 1996, audited by
KPMG Peat, Marwick. All such financial statements are accurate and complete and
were prepared in accordance with GAAP (except that the interim financial
statements are subject to normal year-end audit adjustments) consistently
applied throughout the applicable periods, and present fairly the financial
condition of the Company as of such dates and the results of its operations and
cash flows for the periods then ended. The balance sheets and footnotes thereto
show all known liabilities, direct or contingent, of the Company and
Subsidiaries as of the respective dates thereof in accordance with GAAP. There
has been no Material Adverse Effect since the date of the latest of such
statements. The Company's fiscal year begins on June 1.

                  3.3 Authorization. The making, execution, delivery and
performance of this Agreement and the Related Documents by the Company have each
been duly authorized by all necessary corporate action. The valid execution,
delivery and performance of this Agreement, the Related Documents and the
transactions contemplated hereby and thereby, are not and will not be subject to
any approval, consent or authorization of any Government Authority. This
Agreement and the Related Documents are the valid and binding obligations of the
Company enforceable against the Company in accordance with their respective
terms.

                  3.4 Absence of Conflicting Obligations. The making, execution,
delivery and performance of this Agreement and the Related Documents and
compliance with their respective terms do not violate or constitute a default,
breach or violation under any

                                       17
<PAGE>   23
Requirements of Law or any covenant, indenture, deed, lease, contract,
agreement, mortgage, deed of trust, note or instrument to which the Company or
the Guarantor is a party or by which it or the Guarantor is bound.

                  3.5 Taxes. The Company and the Guarantor have filed all
federal, state, foreign and local tax returns which were required to be filed,
except those returns for which the due date has been validly extended. The
Company and the Guarantor have paid or made provisions for the payment of all
taxes, assessments, fees and other governmental charges owed, and no tax
deficiencies have been proposed, threatened or assessed against the Company,
which should have a Material Adverse Effect on the Company or the Guarantor. The
federal income tax liability of the Company and the Guarantor has been finally
determined by the Internal Revenue Service and satisfied for all taxable years
up to and including the taxable year ended May 31, 1994 and there is no pending
or, to the best of the Company's knowledge, threatened tax controversy or
dispute as of the date hereof.

                  3.6 Absence of Litigation. There is no pending or, to the
knowledge of the Company, threatened litigation or administrative proceeding at
law or in equity against the Company or the Guarantor which would, if adversely
determined, result in a Material Adverse Effect, and, to the best of the
Company's knowledge after diligent inquiry, there are no presently existing
facts or circumstances likely to give rise to any such litigation or
administrative proceeding.

                  3.7 Accuracy of Information. All information, certificates or
statements given by the Company to the Banks under this Agreement and the
Related Documents were accurate, true and complete in all material respects when
given, continue to be accurate, true and complete as of the date hereof, and do
not contain any untrue statement or omission of a material fact necessary to
make the statements herein or therein not misleading. There is no fact known to
the Company which is not set forth in this Agreement, the Related Documents or
other documents, certificates or statements furnished to the Banks by or on
behalf of the Company in connection with the transactions contemplated hereby
and which will, or which in the future may (so far as the Company can reasonably
foresee), cause a Material Adverse Effect.

                  3.8 Ownership of Property. The Company and the Guarantor each
has good and marketable title to all of its Property, including without
limitation the Property reflected in the balance sheets referred to in Section

after diligent inquiry, conforms to

service marks, copyrights and rights with respect to the foregoing as are

in the aggregate, any infringement upon rights of other Persons. SCHEDULE 3
contains a true, correct and complete list of all real estate owned by the
Company and the Guarantor.

                  3.9 Federal Reserve Regulations. The Company will not,
directly or indirectly use any proceeds of the Obligations to: (a) purchase or
carry any "margin stock" within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System (12 C.F.R. 221, as amended); (b) extend
credit to other Persons for any such purpose or refund indebtedness originally
incurred for any such purpose; or (c) otherwise take or permit any action which
would involve a violation of Section 7 of the Securities Exchange Act of 1934,
as amended, or any regulation of the Board of Governors of the Federal Reserve
System.

                  3.10 ERISA. The Company and anyone under common control with
the Company under Section 4001(b) of ERISA is in compliance in all material

such principal place of business and chief executive office.

                  3.12 Other Names. The business conducted by the Company has
not been conducted under any corporate, trade or fictitious name other than the
names of the Company, the Guarantor, FamTec International, Inc., Spitfire, a
division of the Guarantor, and Rogers & Clarke, a division of the Guarantor, and

                  3.13 Not an Investment Company. The Company is not (a) an

neither the Company nor the Guarantor is in default under or in violation of (a)
any Requirements of Law, (b) any covenant, indenture, deed, lease, agreement,
mortgage, deed of trust, note or other instrument to which the Company or the

which any Property is subject, or (c) any Indebtedness; or if any default or
violation under Sections 3.14(a), (b) or (c) exists, it is an immaterial default
or violation and the failure to cure such default or violation would not result
in a Material Adverse Effect.

                  3.15 Environmental Laws. To the best of the Company's
knowledge, the business of the Company and the Guarantor has been operated in
full compliance with all Environmental Laws noncompliance with which would
result in a Default and neither the Company nor the Guarantor is subject to any

Company or the Guarantor and any of their respective employees which

the Guarantor have not, since the date of the most recent financial statements

         the Company's obligation to pay for any such environmental audit shall
         be limited to an amount not to exceed $3,000 per audit in cases where

                  7.2 Remedies Upon Event of Default. Upon the occurrence of an
Event of Default:

                           (a) specified in clauses (g) or (h) of Section 7.1,
         then, without presentment, notice, demand or action of any kind by the
         Agent or the Banks, all of which are hereby waived: (i) the Revolving
         Loan Commitment and the obligations of the Banks to make or incur any
         Obligations shall automatically and immediately terminate; and (ii) the
         entire amount of the Obligations shall be automatically accelerated and
         immediately due and payable.

                           (b) specified in clauses (a), (b), (c), (d), (e),
         (f), (i) or (j) of Section 7.1, the Banks may, without presentment,
         notice, demand or action of any kind, all of which are hereby waived:
         (i) immediately terminate their respective obligations to make or incur
         any Obligations, and the same shall immediately terminate; and (ii)
         declare the entire amount of the Obligations immediately accelerated,
         due and payable.

                           (c) the Company shall immediately deposit with the
         Agent for the ratable account of the Banks an amount equal to the
         undrawn face amount of all outstanding Letters of Credit to pay all
         amounts which may thereafter be drawn under the Letters of Credit.

                           (d) the Agent and/or the Banks may at any time
         without prior notice or demand set off against any credit balance or
         other money now or hereafter owed it by the Agent and/or the Banks all
         or any part of the Company's obligations (to the Agent and/or the
         Banks, as the case may be) hereunder. The Company hereby grants to the
         Agent and the Banks, as the case may be, a security interest in and
         lien on any such credit balance or other money.

                           (e) the Banks shall have all of the rights and
         remedies provided to the Banks and to the Agent by the Related
         Documents, at law and in equity, by statute or otherwise, and no remedy
         herein conferred upon the Banks or the Agent is intended to be
         exclusive of any other remedy and each remedy shall be cumulative and
         shall be in addition to every other remedy given hereunder or now or
         hereafter existing at law, in equity, by statute or otherwise. In
         addition to and not in lieu of any other right or remedy the Banks
         might have, the Agent at any time and from time to time at the
         direction of the Required Banks may (but shall not be required to) do
         or perform or comply with or cause to be done or performed or complied
         with anything which the Company may be required to do, perform or
         comply with and the Company shall reimburse the Agent or the Banks upon
         demand for any cost or expense which the Agent or the Banks may incur
         in such respect, together

                                       34
<PAGE>   40
         with interest thereon at the rate equal to the rate payable under the
         Revolving Credit Notes following an Event of Default from the date of
         such demand until paid. No failure or delay on the part of the Agent or
         the Banks in exercising any right or remedy hereunder shall operate as
         a waiver thereof nor shall any single or partial exercise of any right
         hereunder preclude any further exercise thereof or the exercise of any
         other right or remedy.

                  SECTION 8 RELATIONSHIP OF AGENT AND BANKS

                  8.1 Appointment. Firstar is hereby appointed Agent hereunder
and under the Related Documents, and each of the Banks irrevocably authorizes
the Agent to act as the agent of such Bank. The Agent agrees to act as such upon
the express conditions contained in this Section 8. The Agent shall not have a
fiduciary relationship in respect of any Bank by reason of this Agreement or the
Related Documents.

                  8.2 Powers. The Agent shall have and may exercise such powers
hereunder as are specifically delegated to the Agent by the terms hereof,
together with such powers as are reasonably incidental thereto. The Agent shall
have no implied duties to the Banks, or any obligation to the Banks to take any
action hereunder except any action specifically provided by this Agreement to be
taken by the Agent.

                  8.3 Action on Instructions of Banks.

                           (a) The Agent shall in all cases be fully protected
         in acting, or in refraining from acting, hereunder or under the Related
         Documents in accordance with written instructions signed by the
         Required Banks (or all Banks, if required by Section 8.4 hereof), and
         such instructions and any action taken or failure to act pursuant
         thereto shall be binding on all of the Banks and on all holders of
         Revolving Credit Notes and all other Obligations. The Agent may at any
         time request instructions from the Banks with respect to any action or
         approval that, by the terms of this Agreement, the Agent is permitted
         or required to take or to grant, and if such instructions are
         requested, the Agent shall be absolutely entitled to refrain from
         taking any action or to withhold any approval and shall not be under
         any liability whatsoever to any Person for refraining from any action
         or withholding any approval under this Agreement until it shall have
         received such instructions by the Required Banks (or all Banks, if
         required by Section 8.4 hereof); provided, however, that the Agent
         shall not in any event be required to comply with any instructions
         given it by the Required Banks (or all Banks, if required by Section
         8.4 hereof) if the Agent determines that such compliance would expose
         it to a material personal liability or is contrary to law or to the
         terms of this

                                       35
<PAGE>   41
         Agreement or the Related Documents, but the Banks shall in all events
         indemnify the Agent from any action taken by it in accordance with the
         instructions of the Required Banks. No Bank shall have any right of
         action whatsoever against the Agent as a result of the Agent acting or
         refraining from acting hereunder or under the Related Documents in
         accordance with instructions by the Required Banks.

                           (b) Without limiting the foregoing, the Agent shall
         not be required to take any action with respect to any Default except
         in accordance with Section 7.2 and this Section. The Agent shall be
         entitled to assume that no Default has occurred and is continuing
         unless the Agent has actual knowledge of such facts or has received
         notice from a Bank in writing that such Bank considers that a Default
         has occurred and is continuing, and which specifies the nature thereof.
         In the event that the Agent shall acquire actual knowledge of any
         Default, the Agent shall promptly notify (either orally or in writing)
         the Banks, and the Company of such Default. If directed by the Required
         Banks (or all Banks, if required by Section 8.4 hereof), the Agent
         shall make demand under the Revolving Credit Notes, the Letters of
         Credit and all other Obligations and take such action and assert such
         rights as are contemplated under this Agreement and the Related
         Documents.

                  8.4 Amendments. The Required Banks (or the Agent with the
consent in writing of the Required Banks) and the Company may enter into
agreements supplemental hereto for the purpose of adding or modifying any
provisions of this Agreement or the Related Documents or changing in any manner
the rights of the Banks or the Company hereunder or waiving any Default
hereunder; provided, however, that no such waiver or amendment shall, unless in
writing and signed by all of the Banks and the Company and acknowledged by the
Agent, do any of the following:

         (a)      increase or extend the Maximum Credit of any Bank (or
                  reinstate any Maximum Credit terminated pursuant to Section
                  2.1(g);

         (b)      postpone or delay any date fixed by this Agreement or any
                  Related Document for any payment of principal, interest, fees
                  or other amounts due to the Banks (or any of them) hereunder
                  or under any other Related Document;

         (c)      reduce the principal of, or the rate of interest specified
                  herein on any Revolving Loan, or any fees or other amounts
                  payable hereunder or under any other Related Document;

         (d)      change the percentage of the Maximum Credits or the aggregate
                  unpaid principal amount of the Revolving Loans

                                       36
<PAGE>   42
                  which is required for the Banks or any of them to take any
                  action hereunder;

         (e)      release or terminate the Guaranty; or

         (f)      amend this Section, the definition of "Required Banks" in
                  Section 1.1 or any provision herein providing for consent or
                  other action by all Banks;

and, provided, further, that no amendment of any provision of this Agreement
relating to the Agent shall be effective without the prior written consent of
the Agent.

                  8.5 Application of Payments. All payments of principal and
interest with respect to the Obligations shall be made to the Agent in
immediately available funds for the ratable account of the Banks. The Agent
shall promptly distribute to each Bank, Pro Rata, the amount of (a) principal
and interest received by the Agent, (b) each Bank's Pro Rata share of any fees,
expenses or charges collected by Agent, and (c) all amounts received by the
Agent upon realization from the Property. Any payment in good funds to the Agent
for the account of a Bank hereunder shall constitute a payment by the Company to
such Bank of the amounts so paid to the Agent, and any Obligations or portions
thereof so paid shall not be considered outstanding for any purpose after the
date of such payment in good funds to the Agent. Notwithstanding the foregoing,
for purposes of clause (c) above, the parties acknowledge that all amounts
received by the Agent upon realization of the Property shall be applied Pro
Rata. All payments or prepayments of principal and interest shall be made Pro
Rata in accordance with the amounts of the Obligations then outstanding. In the
event any Bank shall receive from the Company or any other source any payment
of, on account of, any of the Obligations (whether pursuant to the exercise of
any right of setoff, banker's lien, realization upon any security held for or
appropriated to such obligation, counterclaim or otherwise) other than as
provided above, then such Bank shall immediately purchase, without recourse and
for cash, an interest in the obligations of the same nature held by the other
Banks so that each Bank shall thereafter have a percentage interest in all of
such obligations equal to the percentage interest which such Bank held in the
relevant Obligations immediately before such payment; provided, if any payment
so received shall be recovered in whole or in part from such purchasing Bank,
the purchase shall be rescinded and the purchase price restored to the extent of
such recovery, but without interest. The Company specifically acknowledges and
consents to the preceding sentence.

                  8.6 General Immunity. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable to the Banks or any
Bank for any action taken or omitted to be taken by it or them hereunder or in
connection herewith except for its or their own gross negligence or willful
misconduct.

                                       37
<PAGE>   43
                  8.7 No Responsibility for Loans, Recitals, Etc. The Agent
shall not be responsible to the Banks for any recitals, reports, statements,
warranties or representations herein or in any Related Document or be bound to
ascertain or inquire as to the truth or accuracy of the statements or reports of
the Company or any of its Subsidiaries with regard to the performance or
observance of any of the terms of this Agreement.

                  8.8 Employment of Agents and Counsel. The Agent may execute
any of its duties as Agent hereunder and under the Related Documents by or
through employees, agents, and attorneys-in-fact and shall not be liable to the
Banks for the default or misconduct of any such employees, agents or
attorneys-in-fact selected by it with reasonable care, except as to money or
securities received by it or its authorized agents. The Agent shall be entitled
to advice of counsel concerning all matters pertaining to the agency hereby
created and its duties hereunder and under the Related Documents. The Company
shall be responsible for all costs and expenses of the Agent, including
reasonable attorneys' fees of in-house and outside counsel.

                  8.9 Reliance on Documents, Counsel. The Agent shall be
entitled to rely upon any Revolving Credit Note, request for a Letter of Credit,
notice, consent, certificate, affidavit, letter, telegram, statement, paper or
document believed by it to be genuine and correct and to have been signed or
sent by the proper Person or Persons, and, in respect to legal matters, upon the
opinion of counsel selected by the Agent, which counsel may be employees of the
Agent.

                  8.10 Inspections. At the request of the Banks from time to
time, the Agent shall conduct its customary review of the Company's financial
and collateral records and the Property in accordance with Section 5.4. To
assist each Bank in its own investigation of the Company and the Property, each
Bank may send representatives to accompany the Agent's personnel on such
inspections.

                  8.11 Agent's Reimbursement and Indemnification. The Banks
agree to reimburse and indemnify the Agent Pro Rata (i) for any amounts not
reimbursed by the Company for which the Agent (as Agent and not as a Bank under
this Agreement) is entitled to reimbursement by the Company under this Agreement
or the Related Documents, (ii) for any other expenses incurred by the Agent on
behalf of the Banks, in connection with the preparation, execution, delivery,
administration and enforcement (including collection or disposition of Property)
of this Agreement or the Related Documents and (iii) for any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever which may be imposed
on, incurred by or asserted against the Agent in any way relating to or arising
out of this Agreement or the Related

                                       38
<PAGE>   44
Documents or the transactions contemplated hereby or the enforcement (including
collection or disposition of Property) of any of the terms hereof or of any such
other documents, provided that no Bank shall be liable for any of the foregoing
to the extent they arise from the gross negligence or willful misconduct of the
Agent.

                  8.12 Rights as a Lender. Firstar shall have the same rights
and powers hereunder as any Bank the same as though it were not the Agent, and
the term "Bank" or "Banks" shall, unless the context otherwise indicates,
include the Agent in its individual capacity. Firstar may accept deposits from,
lend money to, and generally engage in any kind of banking or trust business
with the Company or any Subsidiary as if it were not the Agent. Each Bank
acknowledges that the other Banks may continue to accept deposits from, lend
money to, and generally engage in any kind of banking or trust business with the
Company or any Subsidiary independent of the Obligations, this Agreement or the
Related Documents; provided, however, that the Company's or any Subsidiary's
obligations to a Bank from such independent banking activities shall not be
secured by the Property. Notwithstanding the foregoing or Section 8.5, any fees
or other income received by any Bank directly from such independent banking
activities are not to be shared with any other Bank or the Agent.

independently and without reliance upon the Agent or any other Bank and based on
the financial statements prepared by the Company and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and the other Related Documents. Each Bank
also acknowledges that it will, independently and without reliance upon the
Agent or any other Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in

                  8.14 Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Banks and the Company, and the Agent may be
removed at any time with or without cause by written notice received by the
Agent from the Required Banks. Upon any such resignation or removal, the
Required Banks shall have the right to appoint, on behalf of the Company and the
Banks, a successor Agent. If no successor Agent shall have been so appointed by
the Required Banks and shall have accepted such appointment within thirty days
after the retiring Agent's giving notice of resignation, then the retiring Agent
may appoint, on behalf of the Company and the Banks, a successor Agent. Such
successor Agent shall be a commercial bank having capital and retained earnings
of at least $25,000,000. Upon the acceptance of any appointment as Agent
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with

all the rights, powers, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations hereunder
arising after the date of retirement. After any retiring Agent's resignation
hereunder as Agent, the provisions of this Section 8 shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as the Agent hereunder and under the Related Documents.

                  8.15 Noteholders. The Agent may treat the payee of any
Revolving Credit Note as the holder thereof until written notice of transfer
shall have been filed with the Agent, signed by such payee and in form
satisfactory to the Agent.
