PART I

ITEM 1. BUSINESS.
- ------- ---------

GENERAL
- -------

Key Technology, Inc. (the "Company") was incorporated in 1982 to acquire a
vegetable processing equipment business founded in 1948. The Company designs,
manufactures, sells and services process automation systems for the food
processing industry and other industries that process product streams of
discrete pieces. These systems integrate electro-optical automated inspection
and sorting systems, specialized conveying systems and product preparation
systems.

The Company's domestic operations are headquartered in Walla Walla,
Washington and are organized into business units comprised of the Company's two
major product groups: Automated Inspection Systems (AIS) and Specialized
Conveying Systems (SCS). Both of these business units continue to serve
customers in the Company's primary market - the food processing industry -
through common sales and distribution channels.

The Company's European business unit operations are conducted by its
indirect, wholly-owned European subsidiary, KEY/Superior B.V. KEY/Superior B.V.
is a manufacturer of specialized conveying systems sold primarily within Europe.
The Company also utilizes KEY/Superior B.V. as the primary sales and service
organization for its AIS products sold to European customers. KEY/Superior B.V.
is located in Beusichem, The Netherlands.

INDUSTRY BACKGROUND
- -------------------

FOOD PROCESSING INDUSTRY

Historically, defect removal and quality control in the food processing
industry have been labor intensive and dependent upon and limited by the
variability of the work force. Food processors must process large quantities of
raw product through different stages, including sorting to remove defective
pieces and inspection for quality. The frequency and severity of defects in the
raw product is highly variable depending upon local factors affecting crops. The
industry has sought to replace manual methods with automated systems that
achieve higher yield, better quality and reduced cost.

In addition, quality analysis usually involves the manual removal of a
sample of product from the processing line at periodic intervals (typically
every 15 to 30 minutes). Such samples are then analyzed in the plant's
laboratory for color, length, width, area, perimeter, shape and defects. These
imprecise sampling techniques and the potential for human error in performing
the laboratory analysis are sources of error in generating statistical quality
control data. The delay between taking the sample and completing the laboratory
analysis may also result in large amounts of product being produced that do not
meet quality specifications.

The Company's strategy is to solve processing industry problems of high
labor costs, inadequate yields and inconsistent quality by providing automated
inspection systems, real-time quality analysis systems and specialized conveying
systems. The Company's automated inspection systems use advanced optical
inspection technology to improve product yield (more of the good product
recovered) and quality (higher percentage of defective product being removed)
over the manual sorting and defect removal methods historically used by food
processors. In a typical application, a single automated inspection system can
replace 25 to 75 processing line employees, resulting in labor cost savings and
improved yield sufficient to pay for the system in less than one year, as well
as providing significant improvements in product quality.

1


PRODUCTS
- --------

The Company has developed a modular family of product lines that can be
configured in a variety of ways and integrated to provide complete solutions for
specific applications. Advances in any one module can therefore benefit a number
of the Company's products that incorporate optical scanning and image analysis.
Despite the incorporation of sophisticated technology, the Company's products
can be operated by plant personnel with minimal specialized training and are
built to withstand the harsh environments found in processing plants.

The following table sets forth sales by product category for the periods
indicated:

AUTOMATED INSPECTION SYSTEMS

Automated inspection systems are used in processing applications to detect
and eliminate defects during raw product processing. The Company's systems
within this group include the ADR(R) and Tegra(R) systems, representing the
Company's third and fourth generation, respectively, of automated inspection
systems.

All systems in this group use proprietary linear array charged coupled
device ("CCD") mono-chromatic (black and white), color or multi-spectral
cameras. Each of the cameras scan the product-streams, which move at five or ten
feet per second, at the rate of 1,500 or 4,000 times per second and can identify
defects as small as 1/16 of an inch (1.5 mm) in diameter. Systems with
monochromatic cameras are less expensive and are most effective for product that
has a marked disparity in shade between the defect and the good product. Systems
with color cameras are required when a variety of defect and product colors
occur simultaneously or when the difference in shade between the defect and the
good product is more subtle. In 1997, the Company developed multi-spectral
systems which utilize either infra-red or ultraviolet technologies, individually
or in combination with visible light, to identify defects that may not be
detectable by solely using visible light spectra.

Tegra Automated Inspection System. In fiscal 1996, the Company introduced
its fourth generation of automated inspection system sorters. Named Tegra, this
generation of automated inspection systems incorporates a number of
technological and mechanical advances that result in significant improvements to
processing efficiency and product throughput with higher recovery and
defect-removal rates. Tegra was designed to provide a technology platform for
future product development and potential entry into applications and markets not
previously served by the Company. Certain present and potential applications for
Tegra systems include potato products, green beans, dried beans, corn, carrots,
peas, spinach and other leafy vegetables, peaches, pears, nuts, grains, coffee
and tobacco.

Tegra incorporates object-specific IntelliSort(TM) technology. IntelliSort
sorting technology recognizes not only color and size, but also shape. This
capability provides a solution to previously difficult sorting problems, such as
differentiation between green beans and green bean stems. Tegra cameras are
capable of high fidelity color-image processing to scan product at a rate of
over 4,000 times per second, offering a sensitivity to color subtleties beyond
human vision. Tegra also incorporates KeyWare(R) software that substantially
reduces operational complexity. KeyWare consists of application packages, each
specifically designed for a single product category that, together with the

2


system's computer hardware capability and networking software, support all
standard factory control and automation interfaces. These features allow Tegra
to establish data connectivity and communication with a processing plant's
computer network system.

ADR Systems. The Company's ADR systems are used to transport, inspect and
remove defects from potato french fries. The Company believes its ADR system is
the principal optical inspection and defect removal system used in the french
fry processing market. The Company's full capacity ADR systems can process up to
26,000 pounds of product per hour.

ADR systems incorporate proprietary specialized conveyors made up of dozens
of individual urethane belts of alternating profiles that align french fries
into 44 "lanes." Cameras locate defects on the french fries as they travel at
five feet per second on the conveyor belts. Upon detection of a defect,
computers that analyze the image data from the cameras actuate knives mounted in
two rotary cutter wheels to cut the defect from the individual french fry.

AccuScan(R) Quality Control Monitor. AccuScan uses sophisticated optical
scanning technology for automated inspection of products. AccuScan is a
high-definition, true-color optical scanning system that samples and analyzes
product streams on a moving conveyor belt for various quality attributes.
AccuScan consists of an on-line scanner connected to a remote UNIX workstation.
AccuScan uses proprietary color image processing software to provide an
automated analysis of product quality. Data are obtained by analysis of product
images that are captured approximately every 7 seconds from a slip stream of
product on the conveyor belt. Information regarding customer-defined product
variables such as color, length, width, area, perimeter, shape and defects are
statistically analyzed to produce accurate, real-time information about product
quality. The AccuScan's workstation analyzes the image data and provides
real-time quality analysis information in graphical form. The system distributes
this information simultaneously to multiple process locations, allowing
correction of process trends before the process yields large quantities of
out-of-tolerance product. Historical quality data may also be presented to
determine trends, review process limits and provide customer documentation of
product quality. Although revenues from AccuScan systems during fiscal 1998 were
not material, the Company expects that sales from this product line will
increase in fiscal 1999.

Pharmaceutical Inspection System. In fiscal 1996, the Company purchased
certain inventory, trademarks and patents related to a pharmaceutical inspection
product line, the I-300 Pharmaceutical Inspection System, from the Imaging
Division of Oncor, Inc. Using patented spatial color analysis technology, this
product line inspects solid-dose pharmaceuticals, including tablets, capsules
and softgels for broken or missing pieces, foreign products, discoloration or
coating defects, as well as the integrity of capsules. The pharmaceutical
inspection system also verifies labels and the presence of printing and detects
color, size, location and shape defects at processing rates over one million
parts per hour. The Company expects sales of this product line will be a
moderate contributor to automated inspection system revenues during fiscal 1999.

SPECIALIZED CONVEYING SYSTEMS

Conveying systems are utilized throughout the food industry, as well as
other industries, to move large quantities of product within a processing plant,
The Company's specialized conveying systems include the Iso-Flo(R) vibratory
conveyor systems, food pumping systems and belt conveyors. The acquisition of
Superior B.V. in fiscal 1996 added electromagnetic conveyor and spiral elevator
technologies to the Companies conveying systems product line.

Iso-Flo Vibratory Conveying Systems. The Company's principal specialized
conveying system is its patented Iso-Flo vibratory conveyor system, which was
introduced in 1978. The Iso-Flo conveyor is a type of pan conveyor. Pan
conveyors are common throughout industries that process product streams of
discrete pieces, especially the food processing industry. Pan conveyors move
product pieces by vibrating the pan at high frequency along a diagonal axis,
upward and forward. This action propels the product ahead in small increments
and distributes it evenly for close control of movement and presentation.

Most Iso-Flo conveyors are custom designed and engineered by the Company to
customer specifications. Iso-Flo systems are used in a variety of processing
applications, including potato products, vegetables and fruits (green beans,
peas, carrots, corn, peaches, pears, cranberries and apples), snack foods,
cereals, pet foods, poultry, seafood and certain nonfood products.

The Company's patent on its Iso-Flo vibratory conveyor system will expire
in fiscal 1999. The Company considers its vibratory conveyor technology to be a
proprietary core competency. Consequently, investment in research and
development activities related to specialized conveying systems increased in
fiscal 1998, with additional increases expected in fiscal 1999. There can be no
assurance that the expiration of the Iso-Flo patent will not result in increased
competition and decreased sales of the product line.

Food Pumping Systems and Belt Conveyors. The Company's hydro food pumping
systems are used to transport food items over distances and elevations in
processing plants. A typical pumping system consists of a stainless steel
contoured tank and food pump to propel the product, lengths of piping to reach
the destination, and a water removal/product spreading subsystem at the
destination. The systems can be configured so that food processing functions,
such as blanching, cooling and cutting, can also occur during pumping. The
Company also designs and manufactures belt conveyors using a variety of belt
materials.

RAW FOOD PREPARATION SYSTEMS

The Company designs and manufactures raw food preparation systems to
prepare vegetables prior to freezing, canning or other processing. Products in
this group include blanchers, air cleaners, air coolers, froth flotation
cleaners, vegetable metering systems, and bulk handling equipment. These
products represent the Company's most mature product line. Sales of these
products over the years have formed a customer base for sales of other Company
products and are also establishing a customer base in developing country
markets.

PARTS AND SERVICE

The Company typically provides system installation support services which
are included in the sales price of certain of its products, principally the AIS
systems. In addition, the Company generates revenues from the sale of spare
parts and post-sale field and telephone-based repair services to support its
customers' routine maintenance requirements and seasonal equipment startup and
winterization processes. The Company considers its parts and maintenance service
sales to be important potential sources of future revenue growth and expects to
devote additional resources in fiscal 1999 to increase such sales. In response
to increasing customer demand for maintenance and parts services, the Company
introduced a new multi-level service product offering named UpTime(TM) in the
first quarter of fiscal 1999.

CUSTOMERS AND MARKETS
- ---------------------

The Company's primary market is the food processing industry. The largest
market segments for the Company's products have been potatoes (principally
french fries), vegetables and snack foods. The Company has also penetrated other
food market segments, including fruits, cereals and pet foods. The Company
believes many additional applications for its systems exist in both food and
nonfood markets.

The principal potato market served by the Company's systems is french
fries. French fries comprise approximately 90% of the over eight billion pounds
of frozen potato products processed annually in the United States. The expansion
of American-style fast food chains in foreign countries is resulting in parallel
development of the frozen french fry market overseas.

The Company's products are used in the fruit and vegetable processing
market where field-harvested products are cleaned, graded, automatically sorted,
blanched and processed prior to freezing, canning or packaging for sale to
institutional and retail markets. Principal fruit and vegetable market segments
for the Company are green beans, corn, carrots, peas, onions, apples, pears,
cranberries and peaches. In fiscal 1998, the Company expanded its addressable
markets by introducing Tegra-based product applications into the coffee and
tobacco markets. The Company expects that the coffee and tobacco markets may
also provide opportunity for expanded sales of specialized conveying systems.
The Company also sells pharmaceutical systems, together with other products, to
pharmaceutical manufacturers in the United States, Puerto Rico and Europe.

The acquisition of Superior B.V. in fiscal 1996 provided the Company with a
manufacturing base from which it can more rapidly manufacture and deliver
conveying systems to European customers. Export and foreign sales for the fiscal
years ended September 30, 1998, 1997 and 1996 accounted for 37%, 32% and 34% of
net sales in each such year, respectively. Nearly all export sales of products
manufactured in the United States have been denominated in U.S. dollars. Sales
in Europe of spare parts and service, as well as products manufactured in
Europe, are generally denominated in European currencies. In its export and
foreign sales, the Company is subject to the risks of conducting business
internationally, including unexpected changes in regulatory requirements;
fluctuations in the value of the U.S. dollar, which could increase the sales
prices in local currencies of the Company's products in international markets;
tariffs and other barriers and restrictions; and the burdens of complying with a
variety of international laws. Additional information regarding export and
foreign sales is set forth in Note 13 to the Company's Consolidated Financial
Statements for the year ended September 30, 1998.

The Company does not rely on annual recurring sales to particular
customers. However, the Company's customers often make periodic large purchases
of complete systems. Therefore, while in any given fiscal year sales to a single
customer might represent 10 percent or more of the Company's consolidated
revenues, the Company believes the loss of such customer would not have a
material adverse effect on the Company. No single customer accounted for more
than 10% of net sales during fiscal 1998.

The Company markets its products directly and through independent sales
representatives. In North America, the Company operates sales offices in Walla
Walla, Washington; Rockville, Maryland; and Beaver Dam, Wisconsin. The Company
also has a subsidiary in Beusichem, The Netherlands which provides sales and
service to European customers. Sales are made in Australia and New Zealand
through an independent distributor which the Company also licenses to
manufacture certain of its products.

ENGINEERING, RESEARCH AND DEVELOPMENT
- -------------------------------------

At September 30, 1998, the Company's engineering departments had 82
technical and support employees who conduct new product research and
development, sustaining engineering for released products and project
engineering for custom systems. The department includes electronic, mechanical
and software engineers, mathematicians and technical support personnel.

5


The Company's project engineering teams are responsible for engineering and
designing the details of each custom order. A document control team maintains
and controls product documentation and the product modeling database for the
development engineering and project engineering teams as well as the
manufacturing department.

In fiscal 1998, the Company's engineering, research and development
expenses were approximately $4.8 million, compared to $4.4 million and $4.3
million in 1997 and 1996, respectively.

MANUFACTURING
- -------------

The Company maintains two domestic manufacturing facilities, both
located in Walla Walla, and a European manufacturing facility located in The
Netherlands. The Company's current manufacturing facilities and its product
design and manufacturing processes integrate Computer Aided Engineering (CAE),
Computer Aided Design (CAD), Computer Aided Manufacturing (CAM) and Computer
Integrated Manufacturing (CIM) technologies. Manufacturing activities include
process engineering; cutting, welding, fabrication and assembly of custom
designed stainless steel systems; camera and electronics assembly; subsystem
assembly; and system test and integration. The Company manufactures products for
its AIS business unit in a 150,000 square foot facility constructed in 1990. In
response to increased market demand for its products, the Company increased its
manufacturing capacity by leasing another 100,000 square foot facility in Walla
Walla in early 1996. The Company initiated full-scale production operations for
its SCS business unit in this facility during early fiscal 1997. The Company
increased its manufacturing capacity as a result of the acquisition in July 1996
of KEY/Superior B.V. During the fourth quarter of fiscal 1998, the Company
further expanded KEY/Superior B.V.'s manufacturing capacity by leasing and
occupying a 45,000 square foot facility adjacent to its original 18,000 square
foot building, which is currently utilized for warehouse and inventory storage
and is being held to meet future anticipated needs.

The Company manufactures certain of its products to Underwriters
Laboratories, United States Department of Agriculture and Occupational Safety
and Health Administration standards and its domestic manufacturing became
qualified in January 1995 for certification to the ISO-9001 quality management
and assurance standards. The merger of the Company's European operations will
require re-certification of that combined entity to the ISO-9001 standards,
which the Company expects to complete in fiscal 1999. The Company's products
also comply with the Canadian Standards Association (CSA) and European CE
(Conformite Europeene) safety standards.

Certain components and subassemblies included in the Company's products are
obtained from single-source or sole-source suppliers. The Company attempts to
ensure that adequate supplies are available to maintain manufacturing schedules.
Although the Company seeks to reduce its dependence on sole and limited source
suppliers, the partial or complete loss of certain sources of supply could have
an adverse effect on the Company's results of operations and relations with
customers.

BACKLOG
- -------

The Company's backlog as of September 30, 1998 and September 30, 1997 was
approximately $11.1 million and $8.2 million, respectively. Gross orders
exceeded shipments by $2.9 million in fiscal 1998, resulting in a corresponding
increase in backlog from the closing backlog in fiscal 1997. The Company
schedules production based on firm customer commitments and forecasted
requirements. The Company includes in backlog only those customer orders for
which it has accepted purchase orders. However, the Company believes that
backlog is not necessarily a meaningful indicator of future financial results as
it typically ships products ordered within eight to thirteen weeks from the date
of receipt of the order. Large multiple-unit system orders or orders for systems
in high demand may, however, result in longer delivery times.

6


COMPETITION
- -----------

The markets for automated inspection systems and specialized conveying
systems are highly competitive. Important competitive factors include price,
performance, reliability, and customer support and service. The Company believes
that it currently competes effectively with respect to these factors, although
there can be no assurance that existing or future competitors will not introduce
comparable or superior products at lower prices. Certain of the Company's
competitors may have substantially greater financial, technical, marketing and
other resources. The Company's principal competitors are believed to be the SRC
Vision subsidiary of Advanced Machine Vision Corporation, Sortex Inc., the
Pulsarr B.V. and Elbicon N.V. subsidiaries of Barco N.V., Allen Machinery Co.
and FMC Corporation. As the Company enters new markets, such as coffee and
tobacco, it expects to encounter new niche competitors.

PATENTS AND TRADEMARKS
- ----------------------

The Company currently owns twenty-two outstanding United States patents
issued from 1982 through 1998 and twelve outstanding patents issued by foreign
countries, the first of which expires in 1999. As of December 2, 1998, seventeen
United States and foreign patent applications had been filed and are pending.
Additional information regarding patent royalties received by the Company is set
forth in Note 14 to the Company's Consolidated financial Statements for the year
ended September 30, 1998.

The Company has twenty-one registered trademarks and applications pending
for two trademarks. The Company also attempts to protect its trade secrets and
other proprietary information through proprietary information agreements with
employees and consultants and other security measures. The laws of certain
countries in which the Company's products are or may be manufactured or sold may
not protect the Company's products and intellectual property rights to the same
extent as the laws of the United States.

EMPLOYEES
- ---------

At September 30, 1998, the Company had 450 full-time employees, including
231 in manufacturing, 82 in engineering, research and development, 89 in
marketing, sales and service and 48 in general administration and finance. None
of the Company's employees in the United States are represented by a labor
union. The Company has never experienced a work stoppage, slowdown or strike.
The Company considers its employee relations to be excellent.

7



ITEM 2. PROPERTIES.
- ------- -----------

The Company's corporate headquarters and the manufacturing and research and
development facilities for its AIS business unit are in a 150,000 square foot
building located on a 20-acre site in Walla Walla, Washington. This facility was
custom designed and built for the Company, with construction completed in
October 1990. The Company occupies the facility under a lease expiring in 2010.
The Company has the option to purchase the facility and related real property at
any time during the remaining lease term. In response to increased market demand
for its products, the Company increased its manufacturing capacity by occupying
another 100,000 square foot facility in Walla Walla beginning in 1996 under a
lease expiring in 2005. The Company may extend the lease until 2010. The Company
manufactures most of its SCS products in this facility. The Company also
manufactures SCS products in a 45,000 square foot leased facility it occupied in
1998 in Beusichem, The Netherlands. This facility also serves as the
headquarters for the Company's sales and service functions in Europe. The lease
on the facility expires in 2008. In addition, the Company still owns a 18,000
square foot manufacturing facility, located adjacent to its newly leased
facility in The Netherlands, which it vacated in 1998 but currently uses as
warehouse space and intends to hold for future expansion. The Company leases
office space in the United States in Rockville, Maryland and Beaver Dam,
Wisconsin. The Company previously owned a manufacturing facility located in
Milton-Freewater, Oregon which it vacated in 1991 and sold in 1998.


ITEM 3. LEGAL PROCEEDINGS.
- ------- ------------------

From time-to-time, the Company is named as a defendant in legal proceedings
arising out of the normal course of its business. As of December 2, 1998, the
Company was not a party to any material legal proceedings.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.
- ------- ---------------------------------------------------------------

This Annual Report on Form 10-K may include "forward-looking statements"
within the meaning of the federal securities laws, including statements as to
anticipated future results that are based on current expectations and are
subject to a number of risks and uncertainties. The following factors, among
others, could cause actual results or outcomes to differ materially from current
expectations: the ability of the Tegra product line to rebound and sustain an
improved level of customer acceptance; achievement of product performance
specifications and related reduction in product upgrade or warranty expenses;
the ability of new products to compete successfully in either existing or new
markets; product development activities; future costs of materials and other
operating expenses; competitive factors; the risks involved in expanding
international operations and sales; the costs associated with remediating
potential Year 2000 issues; the performance and needs of industries served by
the Company and the financial capacity of customers in these industries to
purchase capital equipment.

INTRODUCTION
- ------------

The Company and its wholly-owned subsidiaries design, manufacture and sell
process automation systems, integrating electro-optical inspection and sorting,
specialized conveying and product preparation equipment.

The ownership structure of the Company's European operations is held
through its wholly-owned domestic subsidiary, Key Technology Holdings U.S.A.,
LLC. Suplusco Holding B.V. is a wholly-owned European subsidiary of Key
Technology Holdings U.S.A., LLC and in turn owns KEY/Superior B.V. In fiscal
1998, KEY/Superior B.V. was formed through the merger of Key Technology B.V. and
Superior B.V., Suplusco Holding B.V.'s former subsidiaries. Suplusco Holding
B.V. and its subsidiary are located in Beusichem, The Netherlands. Additionally,
the Company has a wholly-owned foreign sales corporation (FSC) subsidiary, Key
Technology FSC, Inc., through which a portion of the Company's domestically
originated foreign trade income is exempt from tax at the corporate level.

During fiscal 1998, the Company and GE Capital's Vendor Financial Services
business entered into an agreement creating Key Technology Financial Services
(KTFS). Through KTFS, GE Capital will provide customized financial services to
customers of the Company for the acquisition and servicing of equipment
manufactured and distributed by the Company.

RESULTS OF OPERATIONS
- ---------------------

For the fiscal years ended September 30, 1998, 1997 and 1996, the Company's
net sales were $53.1 million, $57.3 million, and $54.3 million, respectively.
Net sales in fiscal 1998 decreased by 7% compared to fiscal 1997. The decreased
sales in fiscal 1998 resulted principally from a 15% decrease in specialized
conveying systems followed by a 58% decrease in other processing equipment,
partially offset by a 5% increase in automated inspection systems and an 11%
increase in parts and service sales. The decrease in specialized conveying
systems and other processing equipment occurred principally from decreased sales
of these products to domestic customers compared to 1997, which had experienced
a significant increase in sales of such products compared to fiscal 1996.
However, sales by KEY/Superior of products, principally in the specialized
conveying system group, to European customers in fiscal 1998 increased by
approximately 23% to $9.8 million compared to $8.0 million in 1997. The increase
in sales in 1998 of automated inspection systems resulted principally from
increased sales of ADR systems and, to a lesser amount, increased sales of
pharmaceutical systems partially offset by a decrease in total Tegra sales for
the period compared to fiscal 1997.

The decrease in total sales volume of the Company's Tegra automated
inspection systems in fiscal 1998 was due principally to decreased sales of
monochromatic Tegra systems, which were partially offset by increased sales of
color and multi-spectral systems. The majority of the Company's Tegra sales are

11


for systems configured with color cameras, which the Company believes provides
superior detection of defects in most applications. The Company continues to
develop new applications utilizing the Tegra system as a technology platform and
believes that systems configured with color and multi-spectral cameras utilizing
these camera configurations will contribute to growth in revenues in fiscal 1999
as the advantages of this technology become more widely known.

Net sales in fiscal 1997 increased by 5% over fiscal 1996. The increased
sales in fiscal 1997 resulted principally from a 43% increase in revenues from
sales of specialized conveying systems followed by a 21% increase in sales of
parts, service and other processing equipment, partially offset by a 23%
decrease in sales of automated inspection systems. While domestic sales of
specialized conveying systems increased in fiscal 1997 over 1996, the increased
sales in this product group benefited principally from the contribution of a
full year of revenues by Superior B.V., which was acquired early in the fourth
quarter of fiscal 1996. The decrease in sales of automated inspection systems in
fiscal 1997 resulted principally from decreased sales of Tegra automated
inspection systems followed by decreased sales of ADR systems.

Export and foreign sales accounted for 37%, 32% and 34% of total net sales
in fiscal 1998, 1997 and 1996, respectively. The largest market for such foreign
sales in both fiscal 1998 and 1997 was to European customers. Sales in fiscal
1998 to European customers and to customers in other foreign markets increased
by 4% and 15 %, respectively, over the prior year.

Gross profit was 36%, 31% and 39% of sales in fiscal 1998, 1997 and 1996,
respectively. The improved gross profit margins, as a percentage of net sales in
fiscal 1998 compared to fiscal 1997 resulted principally from a shift in product
mix toward higher margin products combined with improved margins in most product
groups. The improved gross margin in 1998 also benefited from decreased warranty
and installation expenses and decreased manufacturing labor and other
manufacturing costs as percentages of sales. During fiscal 1998, the Company
repositioned its warranty policy to offer the industry standard one-year
warranty across all of its product offerings. Previously, the Company had
offered a two-year warranty on Tegra systems compared to a one-year warranty on
its other products. As a result of this change to its warranty period policy and
programs to improve product reliability, the Company expects to experience a
continued improvement in its warranty expense as a percentage of sales in fiscal
1999. The gross margin improvements in fiscal 1998 were offset slightly by an
increase in fixed manufacturing overhead expense, as a percentage of sales,
resulting from the unfavorable effect upon capacity utilization of the decrease
in sales volume compared to the prior fiscal year. The reduced gross profit
margins in fiscal 1997 compared to fiscal 1996 resulted principally from a shift
in product mix toward lower margin products combined with a substantial increase
in Tegra system warranty expenses. Increased manufacturing labor and overhead
expenses as percentages of sales also contributed to the decrease in gross
profit contribution between these periods.

Operating expenses increased to $18.1 million in fiscal 1997 from $17.6
million in fiscal 1997 and from $15.2 million in fiscal 1996 and represented
34%, 31% and 28% of net sales in each such year, respectively. The Company
expects that, as a percentage of net sales, total operating expenses in fiscal
1999 may decrease slightly from fiscal 1998 due to anticipated increases in
sales volume.

Selling and marketing expenses were $8.0 million in fiscal 1998, $8.1
million in fiscal 1997 and $7.4 million in fiscal 1996, and represented 15%, 14%
and 14% of net sales in each such year, respectively. Selling and marketing
expenses in fiscal 1998 decreased compared to fiscal 1997 principally as a
result of decreased commission expenses related to the lower level of product
sales combined with a decreased volume and percentage of those sales sold
through outside representatives to whom the Company pays higher commission
rates. The effect of the decreased commission expenses were partially offset by
increased product promotion and advertising expenses in fiscal 1998 compared to
1997. In fiscal 1997, selling and marketing expenses increased by approximately
9% compared to fiscal 1996 due principally to increased staffing and travel
expenses resulting from the Company's reorganization into business units and

12


expenses associated with the Company's activities in developing a presence in
the pharmaceutical inspection systems market. The Company expects to devote
additional resources in fiscal 1999 to expand its selling efforts and market
presence, both domestically and internationally.

Research and development expenses increased in fiscal 1998 to $4.8 million
from $4.4 million in fiscal 1997 and $4.3 million in fiscal 1996, and
represented 10%, 8% and 8% of net sales in each such year, respectively. The
increase in research and development expenses in fiscal 1998 compared to 1997
resulted from activities to extend the capabilities of Tegra into other
applications and markets, such as coffee and tobacco, and in the development of
a new product for the potato industry. Additional research and development
expenditures were incurred in 1998 in the development of a new adaptation of the
Company's Vis/IR (multi-spectral) scanning cameras that simultaneously uses
visible and infrared illumination for detecting defects in french fries while
ignoring the potato skin. This technology can be used on both the Tegra and ADR
systems. The research and development expenses in fiscal 1997 resulted
principally from expenditures associated with the development of performance
improvements and technical modifications for the Tegra product line, which was
introduced in 1996. The Company expects that research and development expenses
in fiscal 1999 may increase slightly compared to fiscal 1998 and that activities
in fiscal 1999 will focus on continuing to extend the capabilities and
applications of the technologies contained in Tegra, completing the development
of a new product for the potato industry and developing new specialized
conveying system products.

General and administrative expenses increased to $5.2 million in fiscal
1998 from $5.1 million in fiscal 1997 and $3.5 million in fiscal 1996, and
represented 10%, 9% and 6% of net sales in each such year, respectively. General
and administrative expenses increased very modestly in fiscal 1998 compared to
the prior fiscal year principally as a result of expenses related to consulting
and training services to improve the Company's processes and product
reliability. The increase in general and administrative expenses in fiscal 1997
compared to 1996 principally reflected the effect of increased staffing levels
resulting from the reorganization of the Company into two separate business
units in the first quarter of fiscal 1997. General and administrative expenses
in 1997 also increased as a result of expenses associated with the Company's new
European subsidiaries which were included for only the fourth quarter of fiscal
1996.

Other income and expense includes interest income and expense, royalty
income and other income from miscellaneous sources. During fiscal 1998, the
Company received royalty payments of $62,000 compared to total royalty income in
fiscal 1997 of $225,000, which included $125,000 as part of an agreement to sell
certain equipment to one customer, pursuant to which the Company may receive
royalty payments through 2001. Royalty income in fiscal 1996 totaled $481,000.
Net interest income in fiscal 1998 was $88,000 compared to $34,000 in fiscal
1997 and $546,000 in 1996. Decreased interest earnings on reduced balances of
funds invested in cash equivalents and short-term investments and increased
long-term debt resulted in the reduced net interest income in fiscal 1998 and
1997 compared to fiscal 1996.

The Company's European subsidiaries contributed a significant portion of
the Company's earnings before taxes during both fiscal 1998 and 1997. Earnings
before taxes, and before the elimination of profits on intercompany
transactions, for the Company's European subsidiaries were $810,000 and $737,000
in fiscal 1998 and 1997, respectively, and constituted approximately 50% and
118% of such earnings for the Company in those respective years. The Company
expects that sales to European customers of products manufactured both
domestically and in Europe will continue to provide a material contribution to
revenues and net earnings.

The Company's effective income tax rate was 33.5%, 32.0%, and 31.6% for
fiscal 1998, 1997 and 1996, respectively.

Net earnings after tax were $925,000 in fiscal 1998 compared to $422,000 in
fiscal 1997 and $4.9 million in fiscal 1996. Basic net earnings per share were
$0.20, $0.09 and $1.05 in fiscal years 1998, 1997 and 1996, respectively. In
spite of decreased sales volume in fiscal 1998 compared to 1997, net earnings in

13


fiscal 1998 improved over the prior year due to increases in gross margin
resulting principally from a shift in product mix toward higher margin products,
improved margins in most product groups, decreased warranty and installation
expenses, and decreased manufacturing labor and other manufacturing costs as
percentages of sales. The decrease in net earnings in fiscal 1997 compared to
fiscal 1996 resulted principally from the reduced gross margin, which was due to
the shift in product mix to lower margin products, increased warranty expenses
and operating expenses, and decreased interest and other income.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

During fiscal 1998, net cash provided by operating activities totaled $5.1
million compared to net cash used in operating activities totaling $3.9 million
in fiscal 1997 and $2.6 million provided by operating activities in 1996. During
fiscal 1998, cash provided by a decrease in accounts receivable totaled $1.6
million due principally to a decrease in sales volume and improved accounts
receivable management. By comparison, accounts receivable balances during fiscal
1997 and 1996 increased by $73,000 and $5.1 million, respectively, as a result
of increased sales volumes in those years. Operating activities during 1998
provided $1.2 million from a decrease in inventories compared to the use of
$360,000 and $3.8 million which was required to fund increases in inventories in
1997 and 1996, respectively. The Company used $846,000 in cash during fiscal
1998 compared to $4.0 million used in fiscal 1997 to decrease trade accounts
payable balances and accrued customer support and warranty costs and to pay
accrued income taxes and certain accrued payroll liabilities which had been
accrued in the previous fiscal years. By comparison, cash provided during fiscal
1996 totaled $4.4 million resulting from increases in these liabilities.

Net cash resources from investing activities totaling $2.0 million, $2.5
million and $3.1 million were used to fund the acquisition of capital equipment
during 1998, 1997 and 1996, respectively. At September 30, 1998, the Company had
no material commitments for capital expenditures. During fiscal 1998, the
Company received net cash resources totaling $653,000 from the sale of a
previously vacated facility. Cash flows from investing activities in the form of
maturities of short-term investments for the net amounts of $6.1 million and
$2.3 million were utilized to partially fund the Company's operating
requirements in fiscal 1997 and 1996, respectively. There were no such proceeds
from maturities of short-term investments in fiscal 1998. During fiscal 1996,
cash resources totaling $2.8 million were invested in the acquisition of a
subsidiary in Europe, Suplusco Holding B.V., and $377,000 was invested for the
purchase of a product line. No such investing activities for acquisitions or
product line purchases occurred in either fiscal 1998 or 1997.

The Company's cash flows from financing activities were affected by the
repayments of long-term debt during fiscal 1998, 1997 and 1996 totaling
$904,000, $1.6 million and $1.4 million, respectively. Separately, cash flows
from the issuance of long-term debt totaled $409,000, $1.3 million and $833,000
in fiscal 1998, 1997 and 1996, respectively. Proceeds from the issuance of
common stock under the Company's employee stock option and stock purchase plans
during fiscal 1998, 1997 and 1996 totaled $137,000, $239,000 and $96,000,
respectively.

The Company's facility with a domestic commercial bank provides for an
operating line of credit up to $4.0 million. The Company also maintains a credit
facility with a Dutch bank providing for operating lines of credit totaling up
to approximately $798,000, which are available to the Company's subsidiaries in
the Netherlands. At September 30, 1998, the Company had no borrowings under
either of these credit facilities.

The Company's operating, investing and financing activities during fiscal
1998 resulted in increases in cash and cash equivalents totaling $3.4 million
compared to decreases in 1997 and 1996 totaling $562,000 and $1.9 million,
respectively. The balance of cash and cash equivalents totaled $6.3 million,
$2.9 million and $3.5 million at the end of fiscal 1998, 1997 and 1996,
respectively. The Company believes that its cash and cash equivalents, cash
generated from operations and available borrowings under its operating lines of
credit will be sufficient to provide for its working capital needs and to fund
future growth.

14


YEAR 2000 CONVERSION
- --------------------

The Company has initiated an enterprise-wide program to prepare its
computer systems, applications and products for the year 2000 date conversion.
The Company expects to incur internal staff costs as well as consulting
expenses, investments in capital equipment and other remediation expenditures
related to enhancements necessary to achieve a year 2000 date conversion with no
effect on customers or disruption to business operations. The total cost of
compliance and its effect on the Company's future results of operations is still
being determined as a part of the detailed and on-going compliance-planning
program. Management currently believes that total expenditures for the Company's
year 2000 compliance program will be approximately $350,000, including both
capital equipment and operating expense. Expenditures through September 30, 1998
totaled approximately $120,000.

The Company expects that the portion of its year 2000 compliance program
that addresses internal issues should be substantially completed by January 1,
1999 and contains only a moderate to low level of risk. The Company also expects
to continue its assessment of external issues related to suppliers, customers,
utilities and other third parties which are outside of its immediate control.
These activities are expected to continue throughout 1999 and beyond, as
applicable. The Company assigns a higher level of risk to such issues since they
are outside of its immediate control. The Company expects to implement
contingency plans as the requirements for such plans are identified. The costs,
if any, for such contingency plans are expected to be incremental to the
Company's estimated year 2000 compliance program expenditures.

THE EURO CONVERSION
- -------------------

On January 1, 1999, certain member countries of the European Union,
including the Netherlands, are scheduled to establish fixed conversion rates
between their existing sovereign (legacy) currencies and the euro, leading to
the adoption of the euro by these countries as their common legal currency. The
legacy currencies are scheduled to remain legal tender in the participating
countries as denominations of the euro from the date of adoption until January
1, 2002. The Company is currently in the early stages of assessing the effect,
if any, that the adoption of the euro by these countries will have upon its
business.

The terms of sales to European and other international customers of
products manufactured by the Company's domestic operations are typically
denominated in U.S. dollars, although exceptions do occur on an individual case
basis. The Company expects that its standard terms of sales to international
customers will continue substantially in their present form. For the infrequent
sales transactions between international customers and the Company's domestic
operations which are denominated in currencies other than U.S. dollars, the
Company assesses its currency exchange risk and may enter into a currency
hedging transaction to minimize such risk. Therefore, the Company does not
believe that it should experience a material effect on its business which would
be inherently different than risks which currently exist.

The terms of sales to European customers by KEY/Superior, the Company's
subsidiary in the Netherlands, are typically denominated in either Dutch
guilders or the respective legacy currencies of its customers. KEY/Superior's
information systems software currently accommodates such multiple currency
transactions and is expected to integrate euro denominated transactions with
relatively minor difficulty. The Company's European subsidiary expects to
implement a complete conversion to the euro in calendar 1999, well before the
January 1, 2002 deadline.

The Company's European subsidiaries maintain long-term credit facilities
with a Dutch bank and also long-term facility and equipment leases, all of which
currently specify periodic debt service or lease payments denominated in Dutch
guilders. Although the Company expects modifications to such agreements will
occur within calendar 1999, there can be no assurance that such modifications

15


will be accomplished within such time frame or that the interest rates or other
terms of such agreements will be unaffected.

FUTURE ACCOUNTING CHANGES
- -------------------------

In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, Reporting
Comprehensive Income. SFAS No. 130 establishes requirements for disclosure of
comprehensive income and becomes effective for the Company's fiscal year ending
September 1999. Reclassification of earlier financial statements for comparative
purposes is required.

In June 1997, FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information. SFAS No. 131 establishes new standards for
disclosure about operating segments in annual financial statements and selected
information in interim financial reports. The new standard becomes effective for
the Company's fiscal year ending September 1999, and requires that comparative
information from earlier years be restated to conform to the requirements of
this standard. The Company will report on one segment.

KEY TECHNOLOGY, INC. AND SUBSIDIARIES


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
THREE YEARS ENDED SEPTEMBER 30, 1998
- --------------------------------------------------------------------------------


1. THE COMPANY
- -- -----------

Key Technology, Inc. and its wholly-owned subsidiaries (the "Company")
design, manufacture, and sell process automation systems, integrating
electro-optical inspection and sorting, specialized conveying and product
preparation equipment. The consolidated financial statements include the
accounts of Key Technology, Inc. and its wholly-owned subsidiaries, Key
Technology Holdings U.S.A., LLC, and Key Technology FSC, Inc., a foreign
sales corporation (FSC). Suplusco Holding B.V., a wholly-owned European
subsidiary of Key Technology Holdings U.S.A., LLC includes the accounts of
Key Technology B.V. and Superior B.V. During 1998, Key Technology B.V. was
merged with and into Superior B.V. to form KEY/Superior B.V. All
significant intercompany accounts and transactions have been eliminated.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- -- ------------------------------------------

REVENUE RECOGNITION - Sales revenue net of allowances is generally
recognized at the time equipment is shipped to customers or when title
passes. Upon receipt of an order, the Company generally receives a deposit
which is recorded as customers' deposits. The Company makes periodic
evaluations of the creditworthiness of its customers and generally does
not require collateral. An allowance for credit losses is provided based
upon historical experience and anticipated losses.

CASH AND CASH EQUIVALENTS - The Company considers all highly liquid
investments with original maturities of 90 days or less to be cash
equivalents. The Company invests from time-to-time in short-term
investments which consist primarily of bankers acceptances and commercial
paper with original maturities of greater than 90 days and less than one
year. These short-term investments are typically held to maturity and the
carrying value approximates fair value. The Company had no such
investments at September 30, 1998 and 1997.

INVENTORIES are stated at the lower of cost (first-in, first-out method)
or market.

PROPERTY, PLANT, AND EQUIPMENT are recorded at cost and depreciated over
estimated useful lives on the straight-line method. The range in lives for
the assets is as follows:
YEARS
-----
Buildings and improvements 7 to 40
Manufacturing equipment 7 to 10
Office equipment, furniture, and fixtures 3 to 7

GOODWILL AND OTHER INTANGIBLES - Goodwill is amortized over 10 years.
Patent costs are amortized over the estimated useful lives of the related
patents or 17 years, whichever is shorter. Management periodically
evaluates the recoverability of goodwill and other intangibles based upon
current and anticipated net income and undiscounted future cash flows.
Amortization of goodwill and other intangibles was $237,000, $244,000, and
$99,000 for the years ended September 30, 1998, 1997, and 1996,
respectively.

ACCRUED CUSTOMER SUPPORT AND WARRANTY COSTS - The Company provides
customer support services consisting of installation and training to its
customers. The Company also provides a warranty on its products for one or
two years following the date of shipment. Management establishes the
reserve for customer support and warranty costs based upon the types of
products shipped, customer support and product warranty experience and
estimates such costs for related new products where experience is not

24


available. The provision of customer support and warranty costs is charged
to cost of sales at the time such costs are known or estimable.

INCOME TAXES - Deferred income taxes are provided for the effects of
timing differences arising from differences in the reporting of revenues
and expenses for financial statement and income tax purposes under the
asset and liability method using currently enacted tax rates.

FOREIGN CURRENCY TRANSLATION - Assets and liabilities denominated in a
foreign currency are translated to U.S. dollars at the exchange rate on
the balance sheet date. Translation adjustments are shown separately in
shareholders' equity. Revenues, costs, and expenses are translated using
an average rate. Realized and unrealized foreign currency transaction
gains and losses are included in the consolidated statement of earnings
and are not material.

ESTIMATES - The preparation of financial statements in conformity with
generally accepted accounting principles requires 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 reported amounts of revenues and
expenses during the reporting period. Actual results could differ from
those estimates.

FINANCIAL INSTRUMENTS - Statement of Financial Accounting Standards
("SFAS") No. 107, Disclosures About Fair Value of Financial Instruments,
requires disclosure of the estimated fair value of financial instruments.
The carrying value of the Company's cash, receivables, trade payables, and
other accrued liabilities approximates their estimated fair values due to
the short maturities of those instruments.

EARNINGS PER SHARE - In February 1997, the Financial Accounting Standards
Board ("FASB") issued SFAS No. 128, Earnings per Share, which specifies
new standards for computing and disclosing earnings per share. The Company
has adopted this standard and has restated its earnings per share ("EPS")
for prior periods presented. The basic EPS has been computed by dividing
net income by the weighted average number of shares outstanding during
each period. Diluted EPS has been computed by dividing net income by the
weighted average common and common equivalent shares outstanding during
each period using the treasury stock method, if the common equivalent
shares were not anti-dilutive. The difference between the basic and
diluted weighted average shares is due to common stock equivalent shares
resulting from outstanding stock options and warrants. Net income for the
calculation of both basic and diluted EPS is the same for all periods
presented. The calculation of the weighted average outstanding shares is
as follows (in thousands):

1998 1997 1996

Weighted average shares outstanding - basic 4,692 4,674 4,652
Common Stock options and warrants 29 86 125
----- ----- -----
Weighted average shares outstanding - diluted 4,721 4,760 4,777
===== ===== =====

Options to purchase 467,250 shares were outstanding as of September 30,
1998, but were not included in the computation of diluted EPS for the year
then ended because the options' exercise prices were greater than the
average market price of the common stock. These options expire on dates
beginning February 2006 through May 2008.

For the year ended September 30, 1997, options for 172,100 shares of
common stock were not included in the computation of diluted EPS because
the options' exercise prices were greater then the average market price of
the common stock. For the year ended September 30, 1996, there were no
options excluded from the computation of diluted EPS.


FUTURE ACCOUNTING CHANGES - In June 1997, FASB issued SFAS No. 130,
Reporting Comprehensive Income. SFAS No. 130 establishes requirements for

25


disclosure of comprehensive income and becomes effective for the Company's
fiscal year ending September 1999. Reclassification of earlier financial
statements for comparative purposes is required.

In June 1997, FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information. SFAS No. 131 establishes new standards
for disclosure about operating segments in annual financial statements and
selected information in interim financial reports. The new standard
becomes effective for the Company's fiscal year ending September 1999, and
requires that comparative information from earlier years be restated to
conform to the requirements of this standard. The Company will report on
one segment.

RECLASSIFICATIONS - Certain reclassifications were made to prior years'
consolidated financial statements to conform with the 1998 presentation.

3. ACQUISITIONS
- -- ------------

Effective July 1, 1996, the Company acquired all of the outstanding common
stock of Suplusco Holding B.V. and a subsidiary, a manufacturer of
specialized conveying equipment. The purchase price was $3,092,000 and was
accounted for by the purchase method. The excess of the purchase price
over the estimated fair value of net assets acquired amounted to
$1,607,000, which is accounted for as goodwill. The results of operations
of Suplusco Holding B.V. and its subsidiary from July 1, 1996 are included
in the statement of earnings. Assets and liabilities acquired were as
follows (in thousands):


Fair value of assets acquired $5,841
Cash paid for common stock, less cash acquired of $338,000 (2,754)
--------

Liabilities assumed $3,087
========

Pro forma unaudited consolidated operating results of the Company and
Suplusco Holding B.V. and subsidiary for the years ended September 30,
1996, assuming the acquisition had been made as of October 1, 1995, are
summarized below (in thousands, except per share amounts):

(Unaudited)

Net sales $57,428
Net earnings 5,207
Earnings per share 1.12


These pro forma results have been prepared for comparative purposes only
and include certain adjustments such as additional depreciation expense as
a result of a step-up in the basis of property, plant, and equipment,
additional amortization expense as a result of goodwill and certain other
adjustments, together with related income tax effects. They do not purport
to be indicative of the results of operations which actually would have
resulted had the acquisition been in effect on October 1, 1995 or of
future results of operations of the consolidated entities.

Effective July 15, 1996, the Company purchased certain inventories,
trademarks, and patents relating to the pharmaceutical inspection product
line from the Imaging Division of Oncor, Inc. for $377,000.

The Company has agreements with the Port of Walla Walla to lease two
operating facilities which expire in 2010. The Company has the option to
purchase the land and plant under one of the agreements after the fifth
full lease year (1995). The purchase price is determined by reducing the
original plant construction costs of approximately $8,800,000 by one
thirty-fifth for each lease year prior to the exercise of the option and
adding $600,000 for the land, subject to further reductions if exercised
after the fifteenth year of the lease. The Company has leased an operating
facility in the Netherlands, which expires in 2008.

Rental expense for the Company's operating leases referred to above was

11. SHAREHOLDERS' EQUITY

EMPLOYEE STOCK PURCHASE PLAN - Effective February 6, 1996, The Company
adopted an Employee Stock Purchase Plan (the "Plan"). Most employees are
eligible to participate in the Plan. Shares are not available to employees
who already own 5% or more of the Company's stock. Employees can withhold,
by payroll deductions, up to 5% of their regular compensation to purchase
shares. The purchase price is 85% of the fair market value of the common
stock on the purchase date. There were 500,000 shares reserved for
purchase under the Plan. During the years ended September 30, 1998, 1997,
and 1996 the Company issued 10,581, 6,199, and 1,705 shares, respectively.

EMPLOYEES' STOCK OPTION PLAN - Under the 1996 Employees' Stock Option Plan
(the "1996 Plan"), eligible employees may receive either incentive stock
options or nonstatutory stock options and such options may be exercised
only after an employee has remained in continuous employment for one year
after the date of grant. Thereafter, the options become exercisable as
stipulated by the individual option agreements, generally 25% per year on
the anniversary date of the grant. The option price is determined to be
fair market value at date of grant.

The following table summarizes activity under this Plan.

----------------

Balance at September 30, 1998 602,783 $15.19
================


At September 30, 1998, total of shares reserved were 699,083, of which
96,300 were available for grant. At September 30, 1998, options for
240,568 shares were exercisable at prices from $7.00 to $23.25 per share.
At September 30, 1997, options for 137,308 shares were exercisable at
prices from $7.00 to $23.25 per share. At September 30, 1996, options for
74,279 shares were exercisable at prices from $5.28 to $10.75 per share.

During 1995, FASB issued SFAS No. 123, Accounting for Stock-Based
Compensation, which defines a fair value based method of accounting for
employee stock options and similar equity instruments and encourages all
entities to adopt that method of accounting for all of their employee
stock compensation plans. However, it also allows an entity to continue to
measure compensation cost for those plans using the method of accounting
prescribed by Accounting Principles Board Opinion No. 25 ("APB 25").
Entities electing to remain with the accounting in APB 25 must make pro
forma disclosures of net income and, if presented, earnings per share, as
if the fair value based method of accounting defined in SFAS No. 123 has
been adopted.

The Company has elected to account for its stock-based compensation plans
under APB 25. The Company has computed, for pro forma disclosure purposes,
the value of all stock and stock options granted under the Employee Stock
Purchase Plan and the 1996 Employees' Stock Option Plan during 1998, 1997,
and 1996 using the Black-Scholes option pricing model as prescribed by
SFAS No. 123 using the following weighted average assumptions for the
years ended September 30, 1998, 1997, and 1996:

1998 1997 1996

Risk-free interest rate 5.0 % 5.5 % 5.5 %
Expected dividend yield 0 % 0 % 0 %
Expected lives 6 years 6 years 6 years
Expected volatility 62 % 61 % 61 %

Using the Black-Scholes methodology, the total value of stock options
granted during 1998, 1997, and 1996 was $1,097,000, $1,525,000, and
$2,320,000, respectively, which would be amortized on a pro forma basis
over the vesting period of the options (typically five years). The
weighted average fair value of options granted during 1998, 1997, and 1996
was $7.27 per share, $10.64 per share, and $13.64 per share, respectively.

The total compensatory value of stock purchased under the Employee Stock
Purchase Plan during 1998, 1997, and 1996 was $15,000, $16,000, and
$7,000, respectively. The weighted average fair value of the stock
purchased during 1998, 1997, and 1996 was $1.42 per share, $2.63 per
share, and $3.85 per share, respectively.

If the Company had accounted for its 1996 Plan and Employee Stock Purchase
Plan in accordance with SFAS No. 123, the Company's net earnings and
earnings per share would approximate the pro forma disclosures below (in
thousands, except per share amounts):

the plan for the years ended September 30, 1998, 1997, and 1996,

sharing contributions to all employees. Discretionary profit sharing
contributions are determined annually by the Board of Directors. There was
no profit sharing plan expense for the years ended September 30, 1998 and
1997, and $723,000 of expense during the year ended September 30, 1996.

occur, and final settlement occurred in fiscal 1998. The Company paid
$46,000, $75,000, and $92,000 in settlement of certain phantom stock unit
