ITEM 1.  BUSINESS
 
     SpeedFam International, Inc. (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, SpeedFam Co., Ltd. (together with its
subsidiaries and joint ventures, the "Far East Joint Venture") and Fujimi
Corporation (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 primarily 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.
 
     The Company designs, develops, manufactures, markets and services chemical
mechanical planarization, or "CMP," systems used in the fabrication of
semiconductor devices as well as 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.
 
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 publicly-traded
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. In 1971, the
Company decided that the most effective method to 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, a dominant
supplier and distributor of slurries in the Far East region, primarily to
silicon wafer, thin film memory disk and general industrial manufacturers in
North and South America. See "-- Manufacturing and Suppliers" and "Joint Venture
Arrangements -- Fujimi Joint Venture."
 
PRODUCTS
 
     SpeedFam's products include polishing, grinding and lapping equipment and
systems; cleaning systems; other high precision surface processing equipment;
and certain other products used in its customers' manufacturing process,
including slurries. During fiscal years 1998, 1997 and 1996, 84.5%, 84.8% and
78.5%, respectively, of the Company's total revenue (including commissions) was
attributable to the sale of capital equipment, parts and expendables and 15.5%,
15.2% and 21.5%, respectively, of the Company's total revenue was attributable
to sales of slurries.
 
     Applications.  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. One
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
 
                                        3
<PAGE>   4
 
action from the abrasive slurry is used to process silicon wafers, thin film
memory disk media and advanced semiconductor devices.
 
     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 stone), rather than a liquid. Grinding
results in much 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. Semiconductor and thin film memory
disk cleaning systems offered by SpeedFam incorporate one or more of the
following features: ultrasonics, PVA (polyvinyl alcohol) brush scrubbing,
rinsing and drying in a Class 1 cleanroom-compatible system.
 
EQUIPMENT
 
     Semiconductor Chemical Mechanical Planarization (CMP).  The Company's
Auriga system is a five head, two polishing table CMP system capable of
processing 65-90 wafers per hour based on a two-minute polishing cycle. 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 which first shipped in 1994.
These modifications include changes to 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 brush and placed wet into the output cassettes. The system is self-enclosed,
and has its own air filtration and air flow management system. The Auriga offers
compatibility with all commonly used slurry chemistries.
 
     In fiscal year 1998, the Company introduced the Auriga-C, which integrates
cleaning and drying technology into the Company's CMP system thereby providing a
complete 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 cleaning technology. The Auriga-C, the Auriga and the
CMP-V are produced solely by the Company.
 
     Thin Film Memory Disk Media.  The Company sells polishing machines,
pre-deposition cleaning machines and grinding machines for producing aluminum,
nickel-plated and alternative substrates for the thin film memory disk media
market.
 
     The DSM line of manual and automated machines are used in the manufacture
of thin film memory disk media for grinding and polishing. The DSM line of
machines simultaneously processes both sides of a disk substrate and is
available in various sizes. The automated machines in the DSM line are currently
manufactured solely by the Far East Joint Venture.
 
     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. Disk cleaning systems
distributed by the Company are currently produced solely by the Far East Joint
Venture.
 
     Semiconductor Wafers.  The Company supplies chemical mechanical polishing,
double-sided lapping and edge polishing systems to the semiconductor substrates
market.
 
                                        4
<PAGE>   5
 
     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 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.
 
     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 suitable for automated processing is
manufactured by the Far East Joint Venture.
 
     The edge polishing 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 of
edge polishing systems that is marketed and distributed by the Company.
 
     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.
 
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 8 U.S. locations, 4 European locations, and 2 locations in the
Far East. 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 preparation 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.
 
     The Company has entered into a joint venture (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. 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.

the Company's total revenue for 1997. No customer accounted for 10.0% or more of
the Company's total revenue in fiscal year 1998. The Company's ten largest
customers accounted for 56.1%, 59.8% and 64.4% of the Company's total revenue in
fiscal years 1998, 1997 and 1996, respectively.
 
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 all the industries it serves and in addition uses a network of 13
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 device, thin film
memory disk media, semiconductor wafer and general industrial products
industries.
 
     At May 31, 1998, 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
 
                                        6
<PAGE>   7
 
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, 1998, the
Company had 197 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
decreased to approximately $29.6 million at July 31, 1998, from approximately
$66.3 million at July 31, 1997. Approximately $17.1 million, or 57.6% of the
total backlog at July 31, 1998, was 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
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 canceled 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 1998, 1997 and 1996, were
approximately $33.7 million, $19.8 million and $11.5 million, respectively.
 
     At May 31, 1998, the Company had an engineering staff of 49 employees and a
research and development staff of 113 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.
 
     Product Development.  In the first half of fiscal 1998, the Company
commenced sales of the Auriga-C. The Auriga-C is an enhanced version of the
Auriga system and integrates post-CMP cleaning and drying technology to provide
a complete dry-in/dry-out solution. The Company intends to periodically develop
and introduce enhanced versions of its CMP system. The Company is also
developing additional products and product enhancements for the thin film memory
disk and silicon wafer markets. Specifically, in fiscal 1999, the Company is
expected to introduce the Pegasus, a new grinding, lapping, and polishing system
for the thin film memory disk market. The Pegasus is configured for maximum
process control flexibility in aluminum grinding or nickel polishing
applications as well as lapping or polishing of alternative substrates such as
ceramic or glass. The Pegasus is designed for future retrofittable options such
as cassette-to-cassette automation and an
 
                                        7
<PAGE>   8
 
advanced cleaning system. In addition, in the thin film memory disk area, the
Company continues to pursue the development of automated machines and enhanced
processes enabling lower head flying heights. For the silicon wafer market, the
Company introduced in fiscal 1998 a 300mm polisher and an enhanced edge
polishing system.
 
     Typically, the Company cultivates a "user-group" of current and potential
customers to act as technical advisors during the conceptualization of a new
product or a major product enhancement. 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
additional film layers such as copper. The Company has also developed and
introduced an end-point detection metrology system for measuring the film
thickness of oxide and metal layers of advanced semiconductor devices. Although
the Company shipped the end-point detection system for revenue in fiscal 1998,
it continues to perfect the product's process applications. In addition, the
Company is developing 300mm planarization capabilities for its CMP systems.
 
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 15.6%, 14.4% and 19.7% of the Company's total revenue in
fiscal 1998, 1997 and 1996, 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 (specifically for CMP), 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.
 
                                        8
<PAGE>   9
 
     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 including Applied Materials, Inc., Ebara
Corporation and Integrated Process Equipment Corp., and any others that may
enter this market in the future. In addition, certain of the Company's
competitors have longer-standing relationships than the Company with particular
customers, including device manufacturers. These longer-standing relationships
may make it more difficult for the Company to sell its CMP system to such
semiconductor 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
relatively few but 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. 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.
 
EMPLOYEES
 
     At May 31, 1998, the Company had 614 full time employees in the U.S. and
Europe, including 92 in manufacturing, 45 in direct sales, sales administration
and marketing, 197 in field service, 49 in engineering, 113 in research and
development and 118 in general administration. In addition, the Company had 8
temporary contract employees engaged principally in its assembly operations at
its Chandler, Arizona and Des Plaines, Illinois facilities. From time to time
the Company will use temporary employees to respond more rapidly to fluctuations
in assembly and product demand and 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.
 
INTELLECTUAL PROPERTY
 
     The Company currently holds 29 United States patents and 28 foreign patents
in Japan and several Asian and European countries and has 145 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. 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 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.

                           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, and Taiwan and
owns a majority interest in a Japanese subcontract manufacturing organization,
Saku Seiki Co., Ltd. The Far East Joint Venture reorganized its Asian operations
and closed the Thailand and Malaysia subsidiaries in July of 1998. The Far East
Joint Venture operations in China, Hong Kong, Singapore, and Korea 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. The joint venture with Met-Coil Systems Corporation will be
closed in fiscal 1999.
 
     Background.  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 decided 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 publicly-traded 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
 
                                       11
<PAGE>   12
 
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 cooperated 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 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 seven 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, Hatsuyuki Arai, 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 SpeedFam Co., Ltd. and assists
in the overall management of operations. Mr. Arai is the director of CMP
technology and reports to Mr. Tojo. Mr. Yoshida is Chief of the Makuhari Techno
Garden Laboratory 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 1998, 1997 and 1996 fiscal
years, the Company's share of the net earnings of the Far East Joint Venture was
$2.8 million, $5.5 million and $4.8 million, respectively, representing 21.6%,
27.3% and 40.3%, respectively, of the Company's net earnings. In fiscal 1998,
the Far East Joint Venture paid $875,000 in dividends to the Company. 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 fiscal 1998, the equity in net earnings of affiliates decreased from
the prior year primarily as a result of a decrease in net earnings of the Far
East Joint Venture. Revenue of the Far East Joint Venture grew in fiscal 1998
from the same period a year ago. However, the decrease in net earnings was
attributable to strong competitive pricing pressures in the thin film memory
disk market, combined with high production and customer support costs. In
addition, the net earnings of the Far East Joint Venture in fiscal 1998 have
also decreased from the prior year due to the severe economic problems facing
several of the Pacific Rim countries, including a decline in the value of the
currencies of these countries. The Company believes that earnings in the Far
East Joint Venture may be adversely affected in the next fiscal year by a
slowdown in demand for equipment sold into the thin film memory disk and silicon
wafer markets, as well as the current financial difficulties facing several
Asian economies. During fiscal 1998, 1997 and 1996, 4.9%, 7.2% and 5.2%
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, 1998, the Company's equity interest in the Far East
Joint Venture was $20.5 million, representing 6.2% of the Company's total assets
and 7.1% of stockholders' 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

     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 and flat panel
display markets. The Company distributes certain of these machines in the U.S.
and Europe. 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 and
Auriga-C five head systems 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: Nippon Light Metal Co., Ltd. (thin film
memory disk manufacturer), MA Disk (thin film memory disk manufacturer), Kaifa
Technology (thin film memory disk manufacturer), Toyo Kohan Co., Ltd. (thin film
memory disk manufacturer), and Kobe Precision, Inc. (thin film memory disk
manufacturer). During the Far East Joint Venture's fiscal years 1998, 1997 and
1996, sales to certain customers through Fujimi Incorporated, acting as a
distributor, accounted for approximately 24%, 15% and 12% 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 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. In the
 
                                       13
<PAGE>   14
 
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 83 persons based in the major locations where
the Far East Joint Venture maintains a presence, such as Japan, India, Korea,
Singapore, and Taiwan.
 
     Research, Development and Manufacturing.  The Far East Joint Venture
maintains a research and development staff of 77 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 Co., Ltd.,
and a substantial portion are manufactured by unaffiliated third party
subcontractors for the Far East Joint Venture.
 
     Employees.  At April 30, 1998, the Far East Joint Venture had 526 full-time
employees, including 428 in Japan, 22 in Korea, 40 in Taiwan, 17 in India, 15 in
Singapore, 2 in Shanghai, and 2 in Hong Kong. Of these employees, 88 are engaged
in manufacturing, 69 in marketing and sales, 83 in field service, 87 in
engineering, 77 in research and development, 59 in management and 63 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 1998, 1997 and 1996, commissions paid to the Company relating to such
distribution amounted to approximately $9.0 million, $12.4 million and $6.3
million, respectively. Further, the Company purchases certain components used in
its machines from the Far East Joint Venture. During fiscal 1998, 1997 and 1996,
purchases of components from the Far East Joint Venture totaled approximately
$6.3 million, $6.1 million and $7.6 million, respectively.
 
     As of May 31, 1998, Mr. Kouzuma received certain amounts from the Far East
Joint Venture consisting of directors' fees, bonuses and salary. Pursuant to a
proposed agreement between the Company and the Far East Joint Venture, the
Company will compensate Mr. Kouzuma directly for services rendered to the Far
East Joint Venture (consisting of directors' fees, bonuses and salary). The Far
East Joint Venture will pay the Company directly a set amount annually for the
use of Mr. Kouzuma's services. Once the agreement is executed, Mr. Kouzuma will
receive directly from the Far East Joint Venture only payments required under
employee benefit plans, and certain dividends as discussed below.
 
     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 Met-Coil Ltd., SpeedFam
Co., Ltd.'s 50%-owned joint venture. Mr. Kouzuma owns 10.62% of the outstanding
capital stock of Saku Seiki Co., Ltd., a majority owned subsidiary of SpeedFam
Co., Ltd., and serves as a director of Saku Seiki Co., Ltd. Messrs. Farley and
Kouzuma also serve as directors of several subsidiaries of SpeedFam Co., Ltd.,
namely SpeedFam Korea Ltd., SpeedFam Incorporated in Taiwan, SpeedFam India
(Pvt.) Ltd. and SpeedFam (S.E.A.) Pte. Ltd. in Singapore.

FUJIMI JOINT VENTURE
 
     Pursuant to a joint venture agreement dated September 7, 1984, the Company
and Fujimi Incorporated formed Fujimi Corporation (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 was $36.8 million in fiscal 1998, $36.6 million in fiscal 1997 and $19.7
million in fiscal 1996. 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 which can
significantly impact operating profit margins.
 
     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. Marach, Chief Financial Officer of the
Company. The other three directors, Messrs. Isamu Koshiyama, Tadashi Nagotoshi
and Stuart Sawai, are representatives of Fujimi Incorporated. Day to day

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
 
OVERVIEW
 
     The Company designs, develops, manufactures, markets and services chemical
mechanical planarization, or "CMP," systems used in the fabrication of
semiconductor devices as well as other high-throughput precision surface
processing equipment 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
 
                                       17
<PAGE>   18
 
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 order
is shipped.
 
     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 years 1998, 1997, and 1996,
83.7%, 83.6%, and 77.3% 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 fiscal 1997. In
the second quarter of fiscal 1998, the Company began shipments of its latest CMP
enhancement, the Auriga-C. Through May 31, 1998, the Company had sold 10
Auriga-C systems. The Company's CMP systems accounted for 57.2%, 50.2% and
34.7%, of net sales for fiscal 1998, 1997, and 1996 respectively. The Company's
CMP systems generally have higher gross margins 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 years 1998,
1997, and 1996, 16.3%, 16.4% and 22.7%, respectively, of the Company's net sales
was attributable to the sale 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 1998, 1997, and 1996,
commissions accounted for 4.9%, 7.2%, 5.2%, respectively, of total revenue.
Commissions are subject to foreign exchange rate fluctuations which can
significantly impact operating profit margins.
 
     In fiscal 1998, 1997, and 1996, 31.7%, 31.2% and 21.7%, respectively, of
the Company's total revenue was attributable to sales outside of the United
States. In particular, in fiscal 1998, 12.5% of the Company's total revenue was
attributable to sales made to European markets and 19.2% 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
Japanese 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 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 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 $26.5 million at April 30, 1998 (the
end of fiscal 1998 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
                                       18
<PAGE>   19
 
and is not expected in the future to result in a like effect on the cash flows
of the Company. At May 31, 1998, the Company's equity interest in the Far East
Joint Venture was $20.5 million, representing 6.2% of the Company's total assets
and 7.1% of stockholders' 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 "Business -- Joint Venture Arrangements" and the consolidated financial
statements of SpeedFam Co., Ltd. included elsewhere herein.

  Fiscal 1998 Compared with Fiscal 1997
 
     Net Sales.  Net sales for the fiscal year ended May 31, 1998 were $176.2
million, up 9.5% over net sales of $161.0 million in fiscal 1997. Equipment,
parts and expendables accounted for 83.7% of net sales in fiscal 1998 compared
to 83.6% in fiscal 1997. The dollar growth in this segment was attributable to
higher sales of the Company's CMP planarization systems to the semiconductor
industry. In addition, the average selling price of the CMP systems increased
over the prior year due to a shift in product mix to the Auriga and the Auriga-C
from the CMP-V in fiscal 1998. Sales of CMP systems totaled $100.8 million, or
57.2% of net sales, up 24.8% over the $80.8 million of CMP system sales in
fiscal 1997. However, the Company believes that there has been a slowdown in
overall demand for semiconductor manufacturing equipment including CMP systems,
which has slowed sales to the semiconductor device market worldwide. This
slowdown is a result of excess production capacity in both the DRAM and logic
segment and resultant decreasing device prices within the DRAM market segment.
As a result, semiconductor manufacturers are expected to reduce or delay their
investment in manufacturing equipment. In addition, the semiconductor device
market has been affected by the conditions surrounding the economic health of
Asian countries, particularly Korea and Japan. The Company believes that these
market and economic uncertainties will likely have an adverse effect on sales of
CMP systems at least through the next fiscal year.
 
   
     Sales to the thin film memory disk market in fiscal 1998 accounted for
$51.9 million, or 29.4% of net sales, as compared to $59.1 million, or 36.7% of
net sales in fiscal 1997. This decrease was primarily due to a
    
 
                                       19
<PAGE>   20
 
   
decline in sales of equipment to the thin film memory disk market from the prior
year. The technology for the production of thin film memory disks has shifted to
the use of alternative substrates; a majority of those substrates being produced
by Far East manufacturers. Consequently, thin film memory disk manufactures
headquartered in the United States have experienced manufacturing over-capacity
which in turn has reduced capital spending for equipment the Company supplies
from its U.S. operations. The Company expects these manufacturing over-capacity
problems to continue in the U.S. through the next fiscal year. Sales of slurries
increased to $28.8 million in fiscal 1998 from $26.3 million in fiscal 1997. As
a percent of net sales, sales of slurries remained relatively unchanged at 16.3%
in fiscal 1998 compared to 16.4% in fiscal 1997. European net sales increased to
$11.0 million in fiscal 1998 from $9.9 million in fiscal 1997.
    
 
     Commissions from Affiliate.  Commissions from affiliate decreased to $9.0
million in the year ended May 31, 1998, compared to $12.4 million in the year
ended May 31, 1997. The decrease in fiscal 1998, as compared to fiscal 1997, was
due not only to the continued slowdown in the thin film memory disk market, but
also to a global decrease in orders of capital equipment from the silicon wafer
market related to manufacturing over capacity due to slowing demand for wafers
produced by that industry. The Company believes that capital equipment spending
will further decline in the thin film memory disk and silicon wafer industries
in the next fiscal year, in turn lowering commissions from affiliate.
 
   
     Gross Margin.  In fiscal 1998, gross margin was $75.5 million, or 40.8% of
total revenue, compared to $69.9 million, or 40.3% of total revenue, in fiscal
1997. Gross margin increased primarily due to the increased sales of CMP systems
in fiscal 1998. However, the impact of improved gross margins due to higher
sales of CMP systems was mostly offset by declining gross margins on sales to
the thin film memory disk industry, declining slurry margins and lower
commission revenue compared to fiscal 1997. Gross margin was also impacted by an
additional $1.5 million in warranty expense accrued in the fourth quarter of
fiscal 1998. Due to the increasing complexity of the Company's CMP products, and
the importance of maintaining customer good will in the current competitive
environment, management made the decision in the fourth quarter of fiscal year
1998 to accrue for additional equipment warranty to cover the anticipated
customer service costs of its CMP products.
    
 
     Research, Development and Engineering.  In the year ended May 31, 1998,
research, development and engineering expense increased to $33.7 million, or
18.2% of total revenue, compared to $19.8 million, or 11.4% of total revenue, in
fiscal 1997. The increase in both the dollar amount and the percentage of total
revenue is a result of the Company's significant investment in dry-in/dry-out,
end-point detection and 300mm planarization capabilities for its CMP systems;
improvements in CMP systems' reliability and productivity; and various process
technologies for the semiconductor device, thin film memory disk and silicon
wafer markets. In addition, the Company has committed significant technical
support resources to meet the needs of its customers. Even though these
investments negatively impacted operating profits in fiscal 1998, the Company
will continue to invest in research, development, and engineering to maintain
technological competitiveness and meet the process requirements of its
customers.
 
     Selling, General and Administrative.  In fiscal 1998, selling, general and
administrative expense increased to $35.9 million from $28.7 million in fiscal
1997. In fiscal 1998, selling, general and administrative expense increased as a
percent of total revenue to 19.4% from 16.5% in fiscal 1997. This increase in
selling, general and administrative expense 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
through the Far East Joint Venture. In the fourth quarter of fiscal 1998,
selling, general and administrative expense also included an increase in the
allowance for doubtful accounts receivable due to possible exposures in the Far
East as well as severance compensation related to reductions in the Company's
workforce which were made during the quarter.
 
     Other Income (Expense).  Other income increased to $6.0 million in fiscal
1998 from $298,000 of other expense in fiscal 1997. Other income (expense)
consisted primarily of interest income in fiscal 1998. Interest income increased
substantially in fiscal 1998 as a result of the cash infusions from the
Company's two successful equity offerings in February and October of calendar
year 1997.
 
                                       20
<PAGE>   21
 
     Provision for Income Taxes.  The Company's effective tax rate in fiscal
1998 was 29%, compared to 38% in fiscal 1997. The Company's effective income tax
rate in fiscal 1998 differs from the Federal statutory rate primarily as a
result of state taxes, net of the U.S. federal benefit, more than offset by the
tax benefit from a foreign sales corporation and tax exempt investment
securities.
 
     Equity in Net Earnings of Affiliates.  For the year ended May 31, 1998,
equity in net earnings of affiliates decreased to $4.4 million compared to $7.1
million in the year ended May 31, 1997. Revenue of the Far East Joint Venture
grew in fiscal 1998 from the same period a year ago. However, net earnings of
the Far East Joint Venture were down from the prior year due to competitive
pricing pressures for the automated disk polishing systems, which negatively
impacted gross margins, combined with higher costs of producing and servicing
these systems. The Company believes that the earnings of the Far East Joint
Venture may be adversely affected for at least the next fiscal year by both the
slow down in demand for equipment sold into the thin film memory disk and
silicon wafer markets, as well as the current economic and currency crises
facing several Asian economies. Restructuring costs of approximately $742,000
were incurred by the Far East Joint Venture during fiscal 1998 in connection
with the reorganization of its Asian operations which included the closing of
the Malaysia and Thailand subsidiaries in July of 1998.
 
  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 planarization 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
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 to the
thin film memory disk market in fiscal 1997 accounted for $59.1 million, or
36.7% of net sales, as compared to $49.5 million, or 43.5% of net sales in 1996.
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 resulted in the development and sale of the Auriga, and
the development of a post-CMP cleaning technology.
 
     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
                                       21
<PAGE>   22
 
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 primarily as a result of continued strong
demand for products sold to the thin film memory disk and semiconductor wafer
industries by the Far East Joint Venture. 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.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     As of May 31, 1998, the Company had $141.2 million in cash, cash
equivalents and short-term investments, compared to $76.9 million at May 31,
1997. The Company used $25.5 million of cash in operating activities. Net
earnings adjusted for non-cash depreciation and amortization and equity in the
net earnings of affiliates provided $13.0 in cash. However, investments in
working capital used $39.8 million primarily due to growth in inventories,
accounts receivable and decreases in accrued expenses, customer deposits and
income taxes payable. During fiscal 1998, inventories increased as a result of
customer requests to delay shipments of CMP systems until fiscal 1999. Also,
orders built on speculation for delivery in the fourth quarter of fiscal 1998
were not received due to customer cutbacks in capital spending. The Company
established and obsolescence reserve for inventories in the amount of $1.4 and
$1.1 million at May 31, 1998 and 1997, respectively. Accounts receivable
increased from the prior year due to more of the Company's products being sold
into geographic regions with longer collection periods, especially the Far East.
In addition, average collection times increased as customers extended times to
evaluate new tool introductions and enhancements.
    
 
     In fiscal 1998, $61.1 million of cash was used in investing activities
primarily for net purchases of short-term investments and capital expenditures.
The Company made capital expenditures of $32.1 million primarily to purchase
machinery and equipment, land, computer equipment and software and complete
payments for the construction of the corporate headquarters in Chandler,
Arizona.
 
     The Company currently anticipates capital expenditures of approximately
$37.0 million for fiscal 1999. Of this amount, $21.5 million is expected to be
used to complete construction on a new 109,000 square foot Technology Center
next to the corporate headquarters in Chandler, Arizona.
 
   
     In fiscal 1998, net cash provided by financing activities was $120.2
million. The Company has financed its growth in recent years primarily from the
issuance of common stock. In October of 1997, the Company completed a public
offering of common stock. The Company issued 2,327,000 shares of common stock
and received net proceeds of $116.7 million. In addition, for the year ended May
31, 1998, $3.7 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. Also available to the Company is a $60.0 million credit facility
negotiated in August of 1997 with its U.S. bank group. The term of the note is
for three years. As of
    
 
                                       22
<PAGE>   23
 
August 14, 1998, no amounts were outstanding on this loan facility. In addition,
the Company has a L950,000 ($1.6 million) unsecured, multi-currency, revolving
line of credit with the London branch of a U.S. bank. As of August 14, 1998, no
amounts were outstanding on this credit facility.
 
     The Company believes that its current cash position and the current bank
lines of credit will be sufficient to meet the Company's cash needs during the
next 12 months.
 
     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 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 for the fiscal year ended May 31, 1999.
 
     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 for the fiscal year ended May 31, 1999.
 
     SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities" is effective for financial years beginning after June 15, 1999. SFAS
No. 133 establishes accounting and reporting standards for derivative
instruments and hedging activities. The Company is evaluating the new
Statement's provisions and has not yet determined its impact. The Company will
adopt SFAS No. 133 effective June 1, 2000.
 
YEAR 2000
 
     The Company is addressing the issues associated with the programming code
in existing computer systems as the millennium (Year 2000) approaches. The Year
2000 problem is pervasive and complex as virtually every computer operation will
be affected in some way. The Company is aware of and is addressing the potential
computing difficulties that may be triggered by the Year 2000.
 
     The Company has commenced a Year 2000 date review and conversion project to
address all the necessary changes, testing and implementation issues. The
project encompasses three major areas of review: internal systems (hardware and
software), supplier compliance and Company products. The Company has identified
the changes required to its computer programs and hardware. The necessary
modifications to the Company's centralized financial, manufacturing and
operational information systems are expected to be completed by the end of
calendar year 1998. To date, the Company's suppliers have been sent letters
requesting information regarding their own Year 2000 plan, as well as requesting
confirmation that the components supplied by these vendors are Year 2000
compliant. The Company has evaluated the vendor responses which have been
received and concluded that the vendors which have responded either are Year
2000 compliant or are proceeding with their own Year 2000 compliance programs.
The Company will continue to follow-up with vendors with which the Company has a
material relationship and who have not responded to obtain assurances that they
expect to be Year 2000 compliant in time. Equipment and systems manufactured and
supplied by the Company have been evaluated and determined to be free of any
material problems that could be caused by the Year 2000 issue. Management
estimates that the Company's remaining Year 2000 compliance expense will be
approximately $110,000. To date, the Company believes that Year 2000 problems
related to its own internal systems and equipment and systems it sells will not
have a material effect on the Company's business, financial condition and
results of operations. However, there can be no assurance that the systems of
other companies upon which the Company's systems and business rely will be
timely converted or
                                       23
<PAGE>   24
 
that any such failure to convert by another company would not have a material
adverse effect on the Company's business, financial conditions or results of
operations.
 
     To date, the management of the Far East Joint Venture has, in response to a
request by the Company, completed a review of their Year 2000 compliance issue
and has determined that there is not expected to be material adverse effects on
its results of operations as a result thereof.

                CERTAIN FACTORS AFFECTING THE COMPANY'S BUSINESS
 
     Discussed below are certain factors which may affect the Company's
business. This discussion is not exclusive of other factors that may also affect
the Company's business and should be read in conjunction with the other
information contained in this Form 10-K including, without limitation,
information provided in "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
DEPENDENCE ON CMP SYSTEMS
 
     The Company believes that its future growth, if any, depends in large part
upon its ability to grow revenues attributable to its CMP systems and its
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 develop the Company's CMP system may
impact its ability to grow revenue attributable to its CMP systems. In addition,
the continuing slow down in the semiconductor industry impacts the Company's
ability to recognize consistent growth in revenue attributable to 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
system. The failure of the Company to accomplish these objectives would have a
material adverse effect on the Company. See "-- 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 even during economic down
turns in the markets the Company serves, or if such investments negatively
impact operating profits in a reporting period. 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/or introduce enhanced versions of its integrated CMP
system. There can be no assurance that the Company's development of new or
enhanced products, such as enhanced versions of the CMP system, 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. In addition, the Company may incur
substantial unanticipated costs to ensure the functionality and reliability of
its future product introductions early in the product's life cycle. If new
products experience reliability or quality problems, the Company could encounter
a number of problems, including reduced orders, higher manufacturing costs,
delays in collection of accounts receivable and additional service and warranty
expenses, each 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, sales of existing Company products could be
adversely affected. See "Business -- Research, Development and Engineering."

CYCLICAL NATURE OF THE COMPANY'S BUSINESS
 
     The Company's business depends substantially on the capital expenditures of
semiconductor, thin film memory disk media and silicon wafer manufacturers (its
primary markets), which, in turn, depend upon the current and anticipated market
demand for semiconductor devices, memory disks and silicon wafers. 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, thin film memory
disk and silicon wafer industries are currently experiencing downturns which
have led many semiconductor, memory disk and silicon wafer manufacturers to
delay or cancel capital expenditures. The Company's business and results of
operations will continue to be materially adversely affected by these downturns
in its primary markets.
 
     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.
 
INTERNATIONAL BUSINESS
 
     In fiscal 1998, 1997 and 1996, 31.7%, 31.2% and 21.7%, 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.
Moreover, slurries marketed and distributed by both the Company and the Fujimi
Joint Venture are purchased from Fujimi Incorporated, a Japanese company. The
Company also purchases in Japanese yen certain equipment from the Far East Joint
Venture that the Company then sells in the U.S. and Europe. 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 stockholders' equity.
 
     The Company anticipates that the recent turmoil in Asian economies and the
recent deterioration of the underlying economic conditions in certain Asian
countries will continue to have an impact on its sales, and the sales of its
joint ventures, to customers located in or whose end-user customers are located
in those countries. In addition, revenue and profits may continue to be impacted
as a result of currency fluctuations on the relative price of the Company's
products, or the products of its joint ventures, and restrictions on government
spending. In addition, customers in those countries have faced reduced access to
working capital to fund purchases of the Company's products, or the products of
its joint ventures, due to higher interest rates, reduced
                                       26

bank lending or the deterioration in the customer's or its bank's financial
condition or the inability to access other financing which has negatively
impacted sales to those customers.
 
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, memory disk and silicon wafer
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) competition, such as competitive pressures on prices of the
Company's products and the introduction or announcement of new products by
competitors; (iii) manufacturing and operations, such as fluctuations in
availability and cost of raw materials and production capacity; (iv)
fluctuations in foreign currency exchange rates; (v) 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; (vi) sales and
marketing, such as concentrations of customers, and discounts that may be
granted to certain customers; and (vii) the quarterly operating results of the
Company's joint ventures, which the Company accounts for on the equity method;
as well as other factors, such as levels of expenses relative to revenue levels,
personnel changes and generally prevailing economic conditions.
 
     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.
 
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
                                       27
<PAGE>   28
 
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."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The stock price of the Company may be subject to wide fluctuations and
possible rapid increases or declines in a short time period. These fluctuations
may be due to factors specific to the Company such as variations in quarterly
operating results or changes in analysts' earnings estimates, or to factors
relating to the industries in which the Company operates and sells or to the
securities markets in general, which, in recent years, have experienced
significant price fluctuations or to global economic events. These fluctuations
often have been unrelated to the operating performance of the specific companies
whose stocks are traded.
 
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."

Although the Company believes that the expectations reflected in any such
forward-looking statements are reasonable; no assurance can be given that any
such expectations will prove correct. Such forward-looking statements involve
known and unknown risks, uncertainties and other factors including those
described above which may cause the actual results, performance or achievements

                          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, 1998 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, 1998.
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, 1998 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, 1998 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     SpeedFam International, Inc. (the Company), an Illinois corporation,
designs, develops, manufactures, markets, and services chemical mechanical
polishing, 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, parts, and expendables used in its customers' manufacturing processes.
The Company's customers are primarily located in the United States, Europe, and
the Far East.
 
  (a) Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and the following wholly owned subsidiaries:
 
<TABLE>
<CAPTION>
                       SUBSIDIARIES                           INCORPORATED
                       ------------                           ------------
<S>                                                          <C>
SpeedFam Corporation.......................................  United States
SpeedFam Limited...........................................  United Kingdom
SpeedFam GmbH..............................................  Germany
</TABLE>
 
     All significant intercompany balances and transactions have been
eliminated. Non-U.S. subsidiaries are included in the consolidated financial
statements based upon fiscal years ended April 30. The Company's fiscal year
ends on May 31.
 
     The Company's investments in the common stock of affiliates SpeedFam Co.,
Ltd. (a Japanese corporation, 50% owned) and Fujimi Corporation (an Illinois
corporation, 50% owned) are accounted for by the equity method using fiscal
years that end April 30 and May 31, respectively.
 
  (b) Cash and Cash Equivalents and Short-term Investments
 
     Cash and cash equivalents include deposits in banks and highly liquid
investments with original maturities of three months or less.
 
     All of the Company's short-term investments are classified as
held-to-maturity securities. These securities are recorded at amortized cost,
adjusted for amortization of premiums and accretion of discounts to maturity.
Such amortization and accretion, as well as any interest on the securities, is
included in interest income.
 
  (c) Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.
 
  (d) Property, Plant, and Equipment
 
     Property, plant, and equipment are stated at cost. Depreciation is provided
on the straight-line method over the estimated useful lives of the assets.
Depreciation expense was $4,394, $2,795, and $1,172 in fiscal years 1998, 1997,
and 1996, respectively. The estimated useful lives of the assets are as follows:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
  (e) 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.
 
   
  (f) Revenue Recognition
    
 
   
     Sales of the Company's products are recorded upon customer acceptance, or
shipment if no customer acceptance is required, at which time title passes to
the customer. Customer acceptance refers to the sign off by the customer that
the equipment is complete and has passed all tests satisfactory to the customer.
Installation of the equipment is generally completed within 30 to 60 days of
acceptance.
    
 
   
  (g) Installation and Warranty Costs
    
 
   
     Costs to be incurred by the Company related to product installation and
warranty fulfillment are accrued at the date of customer acceptance, or shipment
if no customer acceptance is required, and are estimated by the Company based on
past experience. The accrual for product installation and warranty fulfillment,
included in accrued expenses in the consolidated balance sheets, was $5,628 and
$5,510 at the end of fiscal years 1998 and 1997, respectively.
    
 
  (h) Foreign Currency Translation
 
     Assets and liabilities of the Company's non-U.S. operations have been
translated using the exchange rates in effect at each balance sheet date.
Results of operations are translated using the average exchange rates prevailing
throughout each period. Local currencies are considered the functional
currencies of the Company's foreign entities. Foreign currency exchange rates
used to translate the financial statements are summarized below:

  (i) Treasury Stock
 
     The Company accounts for treasury stock using the cost method. All of the
Company's treasury stock was retired upon completion of the Company's initial
public offering of common stock in October, 1995 (see note 15).
 
  (j) Earnings Per Share
 
     In fiscal year 1998, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 128, "Earnings per Share." SFAS No. 128 replaced the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings

per share excludes any dilutive effects of options, warrants, and convertible
securities. Diluted earnings per share includes the effect of all potential
common shares that are dilutive and outstanding during the reporting period.
Earnings per share amounts for all periods presented have been restated to
conform to SFAS No. 128.
 
     The following table sets forth the computation of basic and diluted
earnings per share:

     Options to purchase 457 shares of common stock, at an average price of
$38.16 per share, were outstanding during 1998, but were not included in the
computation of diluted earnings per share because the options' exercise price
was greater than the average market price of the common shares and, therefore,
the effect would be antidilutive.

  (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 Financing
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 11 contains a summary of
the pro forma effects on reported net income and earnings per share for 1998,
1997 and 1996 as if the Company had elected to recognize compensation cost based
on the fair value of the options granted at grant date.
 
  (p) Derivative Financial Instruments
 
   
     The Company uses derivative financial instruments to offset exposure to
market risks arising from changes in foreign exchange rates. Derivative
financial instruments currently utilized by the Company primarily include
foreign currency forward contracts. The Company evaluates and monitors
consolidated net exposures by currency and maturity, and external derivative
financial instruments correlate with the net exposures in all material respects.
Gains and losses on hedges of existing assets and liabilities are included in
the carrying amounts of those assets or liabilities and are ultimately
recognized in income when those carrying amounts are converted. Gains or losses
related to hedges of firm commitments are deferred and included in the bases of
the transactions when they are completed. Gains or losses on unhedged foreign
currency transactions are included in income as part of cost of sales. Gains and
losses on derivative financial instruments which protect the Company from
exposure in a particular currency, but do not currently have a designated
underlying transaction, are also included in income as part of cost of sales. If
a hedged item matures, or is sold, extinguished, terminated, or is related to an
anticipated transaction that is no longer likely to take place, the derivative
financial instrument is closed and the related gain or loss is included in
income as part of cost of sales.
    
 
  (q) Reclassifications
 
     Certain reclassifications have been made in the fiscal 1997 and fiscal 1996
financial statements to conform to the fiscal 1998 presentation.

</TABLE>
 
     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 1998, there was approximately $26,372 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.
 
(7) LONG-TERM DEBT
 
     The Company has a term loan payable in monthly installments of $26
(including interest at a fixed rate of 9.25%) beginning April 1, 1994 for five
years. The balance due is $248 and $522 at May 31, 1998 and 1997, respectively.
As all amounts due will be repaid during fiscal year 1999, the balance is shown
as a current liability at May 31, 1998. The term loan payable is secured by
certain machinery of SpeedFam Corporation.
 
     On August 29, 1997, the Company negotiated a new unsecured credit facility
with its U.S. bank group. The new credit agreement provides for a revolving loan
facility in the amount of $60,000 with a term of three years. If the loan is
utilized, principal will be repaid at the end of the loan term. Interest will
accrue and be paid monthly on the outstanding balance based on a 90 day LIBOR
rate plus 25 to 100 basis points. The Company must meet certain financial
objectives each year as defined in the credit agreement. At May 31, 1998, no
amounts were outstanding on this loan facility.
 
     On October 31, 1996, SpeedFam Limited in the United Kingdom, a wholly owned
subsidiary of SpeedFam International, Inc., entered into a L950 ($1,587)
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. If the line of credit is utilized, interest
will accrue on the outstanding balance at 2.0% above the bank's base rate (7.25%
and 6.0% at April 30, 1998 and 1997, respectively). As of April 30, 1998 and
1997, no amounts were outstanding on this credit facility.
 
(8) 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 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 $1,635, $1,235, and $917 in fiscal years 1998, 1997, and 1996,
respectively.
 
     Future minimum lease payments for all noncancelable operating leases having

     All currency forward contracts outstanding at May 31, 1998 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.
 
(10) SAVINGS AND PROFIT-SHARING PLANS
 
     The Company maintains defined-contribution savings and profit-sharing plans
for its employees. The plans cover certain employees who meet length of service
requirements. Expenses under the plans, determined by the Company's Board of
Directors, aggregated $143, $2,414, and $1,443 in fiscal years 1998, 1997, and
1996, respectively.
 
(11) 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 may be granted to purchase up to 2,500,000
shares of the Company's authorized but unissued common stock. 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.

     As permitted under SFAS No. 123, the Company has elected to follow APB No.
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
fiscal years 1998, 1997 and 1996 consistent with the provisions of SFAS No. 123,
the Company's net income and earnings per share would have been reduced to the
pro forma amounts indicated below:

     In accordance with the provisions of SFAS No. 123, pro forma net income
reflects only options granted in fiscal years 1998, 1997 and 1996. 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 fiscal years
1998, 1997 and 1996.

     The pro forma net income and earnings per share listed above includes
expense related to the Company's 1995 Employee Stock Purchase Plan. The fair
value of grants under the employee stock purchase plan is estimated on the grant

assumptions for grants made in fiscal years 1998, 1997 and 1996:

     Intersegment sales are not material. Segment operating profit represents
total revenue less cost of sales and operating expenses, and excludes equity in
net earnings of affiliates, general corporate expenses, interest income and
expense, and income taxes. Segment identifiable assets are those assets employed
in each segment's operation, including an allocated value. Corporate assets
consist primarily of cash and cash equivalents, investments, and other assets
not employed in production.

(15) OFFERINGS OF COMMON STOCK
 
     In October 1995, the Company completed its initial public offering of
common stock. The Company issued 2,928 shares of common stock and received
proceeds of $28,284, net of underwriters' discounts and commissions and offering
expenses.
 
     In February 1997, the Company completed an additional public offering of
common stock. The Company issued 2,500 shares of common stock and received
proceeds of $77,673, net of underwriters' discounts and commissions and offering
expenses.
 
     In October 1997, the Company completed a public offering of common stock.
The Company issued 2,327 shares of common stock and received proceeds of
$116,704, net of underwriters' discounts and commissions and offering expenses.
 
   
(16) FAIR VALUE OF FINANCIAL INSTRUMENTS
    
 
   
     The Company's financial instruments at May 31, 1998 and 1997 include cash
equivalents, short-term investments, trade receivables, trade payables, foreign
exchange contracts, and long-term debt. The carrying value of cash equivalents,
short-term investments, trade receivables, and trade payables approximates fair
value because of the short maturity of these instruments. Fair values relating
to foreign currency contracts (used for hedging purposes) reflect the estimated
net amounts that the Company would receive or pay to terminate the contracts at
the reporting date based on quoted market prices of comparable contracts and are
not material at May 31, 1998 and 1997. The fair value of the Company's long-term
debt is not materially different from its financial statement carrying value.
The fair value of the Company's long-term debt is estimated based on current
rates offered to the Company for debt of the same remaining maturities.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors
SpeedFam Co., Ltd.:
 
     We have audited the accompanying consolidated balance sheets of SpeedFam
Co., Ltd. and subsidiaries as of April 30, 1998 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, 1998. 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 subsidiaries as of April 30, 1998 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, 1998, in conformity with generally accepted accounting
principles.

  (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 $5,256, $3,542 and $2,148 in fiscal years 1998, 1997,
and 1996, respectively. The estimated useful lives of the assets are as follows:

Machinery and equipment.....................................    3 to 13 years
Furniture and fixtures......................................    2 to 20 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 historical 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:

  (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 fiscal year 1997 and 1996 financial statements have
been reclassified to conform with the fiscal year 1998 financial statement
presentation.

  (o) Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of
 
     The Company's long-lived assets and certain identifiable intangibles are
reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. Recoverability of
assets to be held and used is measured by a comparison of the carrying amount of
an asset to future net cash flows (undiscounted and without interest charges)
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceed the fair value of the assets.
 
     Assets to be disposed of are reported at the lower of the carrying amount
or fair value less costs to sell.

     The Company recorded a valuation allowance of $378 for deferred tax assets
at the end of fiscal year 1998. There was no valuation allowance at the end of
fiscal year 1997. Net deferred tax assets are considered realizable due to the
expectation of future taxable income. Deferred income tax benefits included as a
component of stockholders' equity related to unrealized gains and losses on
marketable securities aggregated $69 and $184 at the end of fiscal years 1998
and 1997, respectively.
 
     At April 30, 1998, certain subsidiaries have net operating loss
carryforwards for income tax purposes of $878 which are available to offset
future taxable income, if any, through fiscal year 2003.
 
     Amendments to Japanese tax regulations were enacted into law on March 31,
1998. As a result of these amendments, the normal income tax rate was reduced
from approximately 51% to 47% effective beginning with the Company's fiscal year
1999. Current income taxes were calculated at the rate of 51% in effect for
fiscal year 1998. Deferred income taxes were calculated at the rate of 47%.
 
     A reconciliation between the Company's effective tax rate and the expected
tax rate of 51% in Japan on earnings before income taxes and minority interest
is as follows:

     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 the end of fiscal year 1997
have been examined by the Japanese tax authorities.

(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
1998 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 1998 and
1997 amounted to $4,905 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 1998 and 1997 amounting to $349 and $548, respectively, is
classified as other assets in the accompanying consolidated balance sheets. The
retirement benefit expenses amounted to $1,492, $1,545, and $520 in fiscal years
1998, 1997, and 1996, 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 1998 and 1997 of $221 and
$229, 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 $28, $67, and $222 in fiscal years
1998, 1997, and 1996, 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 in which they operate. The legal reserve included as a

(13) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments at April 30, 1998 and 1997 include cash
equivalents, trade receivables, short-term investments, short-term borrowings,
trade payables, noncurrent receivables, long-term debt, and obligations under
capital leases. The carrying amount of cash equivalents, trade receivables,
short-term borrowings, 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.
 
(14) SUBSEQUENT EVENT (UNAUDITED)
 
     Subsequent to year end, the yen has experienced a devaluation against the
U.S. dollar. The yen has been devalued from 132 yen/dollar as of April 30, 1998
to approximately 143 yen/dollar as of August 20, 1998. This devaluation of the
yen resulted in a reduction in stockholders' equity of approximately $3 million
as of August 20, 1998. It is not possible to determine what impact, if any, the
devaluation will have on the Company's 1999 operating results.
