ITEM 1.   BUSINESS

THE COMPANY

     Hutchinson Technology Incorporated (the "Company") was incorporated in 
1965 in Minnesota.  The Company is the world's leading supplier of suspension 
assemblies for hard disk drives. The Company estimates that it produces 
approximately 70% (plus or minus 10 percentage points) of all suspension 
assemblies sold to disk drive manufacturers and their suppliers, including 
recording head manufacturers, worldwide. Suspension assemblies are critical 
components of hard disk drives that hold the recording heads in position 
above the spinning magnetic disks. The Company's suspension assemblies are 
manufactured with proprietary technology and processes to uniform and precise 
specifications that are critical to maintaining the necessary microscopic 
clearance between the head and disk. During the fiscal year ended September 
27, 1998, the Company shipped approximately 516 million suspension assemblies 
of all types. The Company is a supplier to nearly all domestic and many 
foreign-based users of suspension assemblies, including Applied Magnetics, 
IBM and its affiliates, Maxtor, Quantum, Read-Rite, SAE Magnetics/TDK, 
Samsung, Seagate Technology, Toshiba, Western Digital and Yamaha.  The 
Company developed its leadership position in suspension assemblies through 
research, development and design activities coupled with a substantial 
investment in manufacturing technologies and equipment, and has maintained 
this position through multiple technological transitions in the disk drive 
industry over the past decade. 

     The Company is focused on continuing to develop suspension assemblies 
which address the rapidly changing requirements of the hard disk drive 
industry. The Company's TSA suspension assemblies are designed to satisfy 
both the new electrical connectivity requirements of the disk drive industry 
as well as the changing market demands and performance standards required by 
its customers. TSA suspensions incorporate thin electrical conductors in the 
suspension itself which replace the fine wires used to connect the recording 
head to the drive's electronic circuitry. The Company anticipates continuing 
acceptance by the disk drive industry of its TSA suspensions, as 

                                       2

<PAGE>

TSA suspensions offer customers opportunities to enhance drive performance by 
eliminating wires that interfere with the recording head's flying 
performance. The Company believes TSA suspensions also enable customers to 
improve yields and throughput, eliminate manufacturing steps and adopt 
automated assembly processes, all of which can lower their overall costs of 
production and improve production efficiencies. During the first fiscal year 
of volume manufacturing of its TSA suspension assemblies (the fiscal year 
ended September 28, 1997), the Company shipped approximately 8 million TSA 
suspensions.  In the fiscal year ended September 27, 1998, the Company 
shipped approximately 85 million TSA suspensions.  The Company believes its 
TSA suspensions, and related follow-on features currently in development, 
will become a disk drive industry standard platform onto which multiple 
features can be integrated.  

INDUSTRY BACKGROUND

     In its November 1998 report, International Data Corporation ("IDC") 
estimated that total revenue in the disk drive industry (defined as unit 
shipments multiplied by the midyear average unit price paid by OEMs for 
quantity 1000+ contracts) would be approximately $26.9 billion in 1998 and 
grow to approximately $32.5 billion in 2000.  Disk drive industry growth has 
been driven by such factors as the growing use of desktop PCs, workstations, 
portable computers and enterprise computing and storage, the increasing 
amount of memory required for software program storage and the continuing 
accumulation of data. In its August 1998 report, TRENDFOCUS stated that 
desktop PCs and servers are expected to grow at 12.7% and 14.8% compound 
annual growth rates, respectively, from 1998 to 2001.  Unit growth rates for 
disk drives and disk drive components are expected to parallel unit growth 
rates for desktop PCs and servers. IDC's report estimates that hard disk 
drive unit shipments will grow at a compound annual growth rate of 13.8% from 
1997 to 2002. 

     The demand for additional storage capacity is stimulated by the 
increasing use of disk drives for non-computer applications such as voice 
mail and video data, the expansion of storage-intensive data warehousing, 
Internet and intranet applications, and the simultaneous use of multiple 
small disk drives, such as systems using Redundant Arrays of Inexpensive 
Disks ("RAID").  According to its November 1998 report, IDC estimated that 
annual shipments of disk drives would reach approximately 139 million in 1998 
and grow to approximately 184 million in 2000. The demand for very high 
capacity disk drives, such as those used in network servers, has been growing 
faster than the overall demand for disk drives. Drives for such network 
servers each typically contain four to ten disks, and therefore eight to 
twenty recording heads and suspension assemblies. In addition, industry 
transitions from thin film inductive recording heads to magneto-resistive 
("MR") heads, which are significantly more sensitive than thin film inductive 
heads in reading data from disks with higher areal densities, and from nano 
heads to the smaller pico heads, have reduced initial production yields of 
the head and disk drive manufacturers. Because a significant portion of head 
yield reduction occurs after the head is bonded onto the 

                                       3

<PAGE>

suspension assembly, low yields often result in increased demand for 
suspension assemblies in order to achieve desired disk drive shipment levels. 

     The disk drive industry, despite the rapid growth in recent years, is also
highly cyclical and from time to time experiences downturns.  Suspension
assembly unit sales have been depressed due to a slowdown in component demand
which began in the latter part of the fiscal 1997 third quarter and continued
throughout the fiscal 1997 fourth quarter and all of fiscal 1998.  The Company
believes the slowdown was due to excess inventory held by drive and recording
head manufacturers and to somewhat softer server and desk-top system demand.  In
addition, some of the major personal computer companies transitioned to
build-to-order manufacturing, decreasing their required disk drive inventory
levels.  Further, data density improvements also resulted in reducing slightly
the average number of suspensions required per drive, from slightly over 5 to
approximately 4.8 suspensions. Total shipments of the Company's suspension
assembly units decreased from a peak of approximately 201 million shipped in the
thirteen weeks ended March 30, 1997 to a low of approximately 122 million
shipped in the thirteen weeks ended September 27, 1998.  End user demand for
storage capacity, however, has not slowed significantly, as rapidly evolving
technology and computer applications continue to require storage devices with
increased capacity and functionality.  The Company does not believe there has
been a significant slowdown in end user demand for storage capacity or a
fundamental shift in technology away from disk drive storage.  The recent
slowdown in component demand did not extend to industry demand for the Company's
TSA suspensions, which has continued to rise.  Demand for the Company's
conventional suspension assemblies started to recover during the latter part of
the fiscal quarter ended September 27, 1998.  However, the Company expects
conventional suspension shipments in fiscal 1999 will trail those of fiscal 1998
as customer demand shifts towards TSA suspensions.

     All hard disk drives incorporate the same basic technology. The principal
components of a hard disk drive are recording disk media, a motor assembly, the
control electronics and a head stack assembly. A head stack assembly consists of
multiple magnetic recording heads attached by suspension assemblies to the
actuator arm. Each disk drive contains one or more (up to thirteen) hard disks
attached to a motor assembly that rotates the disks at high speeds in extremely
close proximity to the magnetic recording heads, each of which is attached to a
suspension assembly. Typically two recording heads (one for each side of the
disk), and therefore two suspension assemblies, are used with each disk in the
disk drive. 

     Suspension assemblies are critical to disk drive performance and
reliability. The design of suspension assemblies is driven by the increasing
performance requirements of new disk drives, principally reduced data access
time, increased data storage density, smaller recording heads and technology
incorporated in the type of recording head used. Technological advances in disk
drives generally require suspension assemblies with specialized design, expanded
functionality and greater precision. One of the major determinants of disk drive
performance and data storage capacity is the microscopic height at which the
magnetic head "flies" above the disk. Suspension assemblies hold the magnetic
recording heads in position and are a significant factor in controlling the
critical flying height of the head above the disk and maintaining the position
of the head on the tracks of data. A typical nominal flying height is about
one millionth of an inch (a sheet of paper is approximately 3,000 millionths of
an inch thick).

                                       4

<PAGE>

     Hard disk drive storage capacity increases as areal density increases.
Improvements in areal density have been attained by lowering the fly height of
the recording head, using smaller recording heads with advanced air bearing
designs, improving other components such as motors and media and using new
recording head types such as those of MR design. As drive manufacturers
transition to smaller pico-sized MR heads, the current process of bonding fine
electrical wires to the recording head and to the rest of the drive's electronic
circuitry is becoming more difficult and costly, and the wires themselves
interfere with the head's flying performance.  The Company developed its TSA
suspension assemblies, which incorporate electrical conductors in the suspension
itself, to address this difficulty.

     The Company continually monitors technological developments in the data
storage arena. On an ongoing basis, the Company reviews technological threats to
the disk drive market and utilizes various universities, consortiums and
industry participants to provide additional third-party insights.

</TABLE>

     During the fiscal year ended September 27, 1998, the Company shipped
approximately 516 million suspension assemblies of all types.  The Company has
developed significant proprietary capabilities in the design and production of
suspension assemblies for both current and emerging disk drive designs. The
Company has been in the forefront of industry technology transitions by
developing improved suspension assemblies in anticipation of several market
shifts to new generations of smaller magnetic heads (mini-to-micro,
micro-to-nano and nano-to-pico). To help develop prototype suspensions, the
Company maintains a test laboratory and computerized systems to simulate and
analyze suspension designs. The Company's ability to predict and modify
suspension assembly performance is especially important in developing
suspensions for high capacity drives and drives with low access times.

     CONVENTIONAL SUSPENSION ASSEMBLIES

     The Company currently has the capacity to produce over 300 variations of 
conventional suspension assemblies based on several standard designs for the 
nano and pico platforms. This capability permits the Company to assist 
customers' design efforts and to rapidly modify its standard designs to meet 
the varied and changing requirements of specific customers. The Company 
believes that its integrated manufacturing approach, closely coupling design, 
tooling and manufacturing, gives it a competitive advantage in quickly 
supplying conventional suspension prototypes and commencing volume 
manufacturing. This manufacturing approach also allows the Company to rapidly 
shift tooling in its conventional suspension assembly production units to 
respond to fluctuating product mix and thereby minimize the size of its 
finished goods inventory. 

     TSA SUSPENSION ASSEMBLIES

     The Company anticipates continuing acceptance by the disk drive industry of
its TSA suspensions, which integrate into the suspension thin electrical
conductors that connect directly with the recording head. The integral etched
copper leads of the TSA suspension are pre-positioned on the suspension assembly
from the head region through the length of the suspension and, in some cases,
along the actuator. The Company believes that this electrical integration will
be a key feature of suspension assemblies as disk drive manufacturers make the
transition to smaller and more complex recording heads. The current process of
using fine electrical wires to attach the smaller head to the rest of the
drive's electronic circuitry is more difficult and costly, involving greater
risk of handling damage as well as interference by the electrical wires with the
head's performance. 

     Electrical integration, a key feature of the Company's TSA suspensions, 
can reduce the manual labor required to attach heads to suspensions and thus 
facilitates automated assembly. TSA suspensions also increase the consistency 
of head flying by eliminating certain wires that can impart forces that 
adversely affect the recording head's flying position. The Company believes 
that similar benefits throughout the head gimbal assembly and head stack 
assembly processes will result in improved yields and increased throughput 
for its customers, which should translate into lower capital investment, 
reduced labor and lower overall costs for such customers. TSA suspensions are 
particularly suited for MR heads, which constitute a major portion of the new 
and smaller types of recording heads that allow increased data storage 
density. MR heads require at least twice as many electrical leads as 
conventional recording heads. For these reasons, TSA suspensions command a 
higher sale price than the Company's conventional suspensions. 

     The Company introduced TSA suspension assemblies to customers and began 
shipping electrically functional engineering samples in the first half of 
fiscal 1996.  During the first fiscal year of volume manufacturing of its TSA 
suspension assemblies (the fiscal year ended September 28, 1997), the Company 
shipped approximately 8 million TSA suspensions.  In the fiscal year ended 
September 27, 1998, the Company shipped approximately 85 million TSA 
suspensions.  TSA suspensions accounted for approximately one percent of the 
Company's fiscal 1997 unit shipments and approximately 16% of the Company's 
fiscal 1998 unit shipments.  The Company expects them to account for 
approximately half of its total unit shipments during fiscal 1999.  To 
further assure customers that the TSA suspensions they require for their 
products will be readily available when and where they are needed, in fiscal 
1998 the Company started offering component-level 

                                       6

<PAGE>

parts, such as load beams, base plates and flexures for both conventional and 
TSA suspensions, for sale to competitive suspension assembly manufacturers.  
As demand for TSA suspensions increases, customers will have an additional 
source of supply for critical suspension assemblies. 

     TSA suspension assemblies are adaptable to future developments in disk 
drive design and manufacturing. Variations of TSA suspension assemblies now 
in development by the Company offer promising solutions to the challenges 
posed by increasing areal density to increase disk drive capacity. As the 
number of data tracks per disk increases to achieve increased areal density 
(tracks are expected to increase from the current 5,000 per inch to 20,000 or 
more per inch within the next few years),   recording heads must be 
positioned above data tracks with more precision than current disk drive 
technology allows. A TSA suspension incorporating a second stage actuator 
could provide the degree of precision required to properly position the head 
over a data track as track densities increase. Similarly, an increase in 
areal density achieved by increasing the number of data bits recorded per 
linear inch on each data track will require preamplification to overcome 
signal to noise problems that occur as bit density increases. Electrical 
termination pads incorporated in a TSA suspension provide a means of 
positioning a preamplifier closer to the recorded data to reduce the signal 
to noise problem. Additional variations for other TSA suspension products are 
also in development. The Company anticipates that TSA suspensions and these 
related follow-on features will result in TSA products becoming a disk drive 
industry standard platform. 

     The Company has invested a substantial amount of financial, management, 
engineering and manufacturing resources in the development of its TSA 
suspension assemblies. If continuing market acceptance and/or production of 
the Company's TSA suspension assemblies were delayed for any reason or if 
widespread market acceptance of the TSA product platform is not achieved, the 
Company's business, financial condition and results of operations could be 
materially adversely affected. Furthermore, if the Company fails to complete 
the transition to profitable high-volume production of its TSA suspension 
products or determines that TSA suspension assemblies cannot be produced 
profitably in the quantities and to the specifications required by customers, 
the Company's business, financial condition and results of operations could 
be materially adversely affected.

     OTHER PRODUCTS

     The Company manufactures a small amount of etched and stamped components 
used in connection with or related to suspension assemblies. The Company also 
is engaged in the development of product opportunities in the medical devices 
market. In February 1998, the Company received FDA clearance for marketing in 
the U.S. a monitor that measures the percentage of oxygenated blood in 
tissue. The monitor is now the subject of clinical trials at several 
hospitals. The Company does not expect any medical-related revenue in fiscal 
1999, and there can be no assurance that the Company's efforts will result in 
marketable products or that such products will ever generate significant 
revenue. 

MANUFACTURING

     The Company's manufacturing strategy focuses on enhancing its ability to 
reliably produce suspension assemblies in high volume and with the precision 
required by its customers, by 

                                       7

<PAGE>

investing in the development of advanced process and measurement systems and 
the design of its automated production equipment, as well as in additional 
manufacturing plants and equipment. The Company also has adopted an 
integrated manufacturing approach that closely couples design, tooling and 
manufacturing. This integrated approach has facilitated the development, 
implementation and high-volume production of new suspension assembly 
products. Effective use of this integrated approach, together with the 
Company's investment in equipment, has increased production yields and 
efficiency, and has been an important factor in reducing the Company's 
manufacturing costs. 

     A suspension assembly consists of two or three components that are laser 
welded together. TSA suspension assemblies also incorporate electrical leads 
which provide electrical connection from the recording head to the disk 
drive's electronic circuitry. Alignment, adjustment and freedom from 
imperfections and contaminants are of critical importance. The Company's 
products require several manufacturing processes, each dependent on different 
technical disciplines, to ensure the high degree of precision and process 
control necessary to meet strict customer tolerances and other requirements. 
The Company has developed sophisticated proprietary manufacturing processes 
and controls, and related equipment, which are essential to the precision and 
reliability of its products. The manufacturing processes employed by the 
Company include photoetching, stamping, plasma etching, plating, precision 
forming, laser welding and ultra-cleaning. The photoetching of the 
components, the laser-welding operations which fuse the components together 
and subsequent processing steps are subject to stringent specifications and 
controls. The Company monitors and controls these processes through real-time 
statistical process analysis to track critical parameters and take corrective 
action as required. 

     The Company's critical raw material needs are available through multiple 
sources of supply, with the following exceptions. Certain types of 
photoresist, a liquid compound used in the photoetching process, and the 
stainless steel, copper and polyimide materials that meet the Company's 
strict specifications, are each currently available from only one supplier. 
To protect against the adverse effect of a short-term supply disruption, the 
Company maintains several weeks' supply of these materials. If for any reason 
the Company were unable to continue to obtain these materials in the 
necessary quantities, with the necessary quality and at reasonable prices, 
the Company's results of operations could be materially adversely affected.

     The Company's production processes require the storage, use and disposal 
of a variety of chemicals that are considered hazardous under applicable 
federal and state laws. Accordingly, the Company is subject to a variety of 
regulatory requirements for the handling of such materials. If an accident 
were to result in significant personal injury or environmental damage, the 
Company's business, financial condition and results of operations could be 
materially adversely affected. 

RESEARCH AND DEVELOPMENT

     The Company participates in an industry that is subject to rapid 
technological change, and its ability to remain competitive depends on, among 
other things, its ability to anticipate such change and to continue its close 
working relationships with the engineering staffs of its customers. As a 
result, the Company has devoted and will continue to devote substantial 
resources to product development and process engineering efforts. As of 
September 27, 1998, the Company employed 

                                       8

<PAGE>

859 engineers and technicians who are responsible for implementing new 
technologies as well as process and product development and improvements. 
Expenditures for these activities in fiscal 1998, 1997 and 1996 amounted to 
approximately $52,235,000, $48,204,000 and $51,212,000, respectively. Of 
those amounts, the Company classified approximately $20,360,000, $20,185,000 
and $27,651,000, respectively, as research and development expenses. 

     The Company's current research and development efforts are principally 
directed to continuing the development of its TSA suspension assemblies and 
related follow-on features to meet ongoing technological advances in the disk 
drive industry, including changing head size, performance standards and 
electrical connectivity requirements for disk drives. 

     The Company entered into a Technology Transfer and Development Agreement 
(the "Technology Sharing Agreement") and a non-exclusive Patent License 
Agreement (the "Patent License Agreement") with IBM during fiscal 1995. Under 
the Technology Sharing Agreement, IBM made available to the Company the 
results of many years of research by IBM into the new integrated lead 
suspension. The Company itself had devoted substantial efforts independent of 
IBM to the research and development of TSA suspensions, and contributed its 
existing TSA suspension technology to the joint effort. As of September 27, 
1998, the Company had made payments totaling $5,500,000 to IBM and will make 
additional payments over the next two fiscal quarters totaling $2,500,000, 
all of which have been recorded as an expense by the Company. In addition, 
certain royalties have been paid and may be payable in the future by the 
Company to IBM under the Technology Sharing Agreement. 

     The Company also is engaged in the development of product opportunities 
in the medical devices market, including a monitor that measures tissue 
oxygen saturation. This monitor recently received FDA clearance for marketing 
in the U.S., and is now the subject of clinical trials at several hospitals. 
For fiscal 1998, 1997 and 1996, research and development expenses allocated 
to medical devices were approximately $3,190,000, $2,725,000 and $1,990,000, 
respectively. There can be no assurance that the Company's efforts will 
result in marketable products or that such products will ever generate 
significant revenue. 

CUSTOMERS AND MARKETING

     The Company's products are sold principally through its own 
eleven-member account management team operating primarily from its 
headquarters in Hutchinson, Minnesota. The Company has one account manager in 
Europe and, through a subsidiary, one account manager and six technical 
representatives in Asia.  The Company's products are sold to original 
equipment manufacturers for use in their products and to subassemblers who 
sell to original equipment manufacturers.  The Company's account management 
team is organized by individual customer and contacts are typically initiated 
with both the customer's purchasing agent and its engineers.  The Company's 
engineers and account management team together actively participate in the 
selling process and in maintaining customer relationships.

                                       9

The Company is a supplier to nearly all domestic and many foreign-based 
manufacturers of hard disk drives and recording heads used in such drives. 
The following table shows the Company's five largest customers for fiscal 
1998 as a percentage of net sales. 

<TABLE>

         <S>                                      <C>

          Yamaha Corporation . . . . . . . . . . .  10 

</TABLE>

     Sales to the Company's five largest customers constituted 84%, 86% and 
87% of net sales, respectively, for fiscal 1998, 1997 and 1996. Significant 
portions of the Company's revenue may be indirectly attributable to large 
manufacturers of disk drives, such as Quantum Corporation, Toshiba 
Corporation and Western Digital Corporation, which may purchase recording 
head assemblies from several different recording head manufacturers that 
utilize the Company's suspension assemblies.

     The Company expects to continue to depend upon a limited number of 
customers for a substantial majority of its sales, given the relatively small 
number of hard disk drive and recording head manufacturers. The Company's 
results of operations could be adversely affected by reduced requirements of 
its major customers.

     Sales to foreign-based enterprises totaled $167,767,000, $88,471,000 and 
$63,898,000 for fiscal 1998, 1997 and 1996, respectively. Sales to foreign 
subsidiaries of U.S. corporations totaled $47,885,000, $83,753,000 and 
$51,564,000 for fiscal 1998, 1997 and 1996, respectively. The majority of 
these sales were to the Pacific Rim region. In addition, the Company has 
significant sales to U.S. corporations which use the Company's products in 
their offshore manufacturing sites. 

BACKLOG

     The Company's sales are generally made pursuant to purchase orders 
rather than long-term contracts.  The Company's backlog of purchase orders 
was approximately $101,541,000 at September 27, 1998, as compared to 
$79,100,000 at September 28, 1997.  Such purchase orders may be changed or 
cancelled by customers on short notice without penalty.  In addition, the 
Company believes that it is a common practice for disk drive manufacturers to 
place orders in excess of their needs during growth periods. Accordingly, the 
Company does not believe that backlog should be considered indicative of 
sales for any future period.

COMPETITION

     The Company believes that the principal factors of competition in the 
suspension assembly market include time to market, product quality, design 
expertise, reliability of volume supply and price.  The Company estimates 
that it produces approximately 70% (plus or minus 10 percentage points) of 
all suspension assemblies sold to disk drive manufacturers and their 
suppliers, including recording head manufacturers, worldwide.  The Company's 
principal competitors are K. R. Precision Co., Magnecomp 

                                       10
<PAGE>

Corporation and Nippon Hatsujo Kabusikigaisha.  Certain users of suspension 
assemblies also have or may develop the ability to fabricate their own 
suspension assemblies.  In addition to competition in the conventional 
suspension assembly market, the electrical interconnect features of the 
Company's new TSA suspensions face competition from wireless interconnection 
technologies that are alternatives to conventional wiring, such as deposition 
circuitry and flexible circuitry which are also being considered for and used 
in drive production.  Although there can be no assurance that the number of 
competitors will not increase in the future or that users of suspension 
assemblies will not develop internal capabilities to manufacture suspension 
assemblies, the Company believes that the number of entities that have the 
technical capability and capacity for producing precision suspension 
assemblies in large volumes will remain small. 

     Other types of data storage systems, such as semiconductor (flash) 
memory, tape memory and laser (optical and CD) drives, may become competitive 
with certain hard disk drive applications, and thereby affect the demand for 
certain of the Company's products. However, given the current state of the 
technologies, flash memories are not expected to be price competitive with 
disk drives and optical and tape memories are inherently much slower than 
disk drives. Accordingly, the Company believes that such technologies will 
not materially impact the market for hard disk drives in the near future. 

INTELLECTUAL PROPERTIES

     Certain equipment, processes, information and knowledge generated by the 
Company and utilized in the manufacture of its products are regarded as 
proprietary by the Company and are protectable under applicable trade secret, 
copyright and unfair competition laws. In addition, if the Company believes 
it has made inventions in manufacturing equipment, products and processes for 
making products where patents might enhance the Company's position, patents 
have been and will continue to be pursued in the U.S. and in other countries. 
As of September 27, 1998, the Company held 51 U.S. patents and nine foreign 
patents, and had 60 patent applications pending in the U.S. and 34 patent 
applications pending in other countries. The Company believes that although 
the patents it holds and may obtain will be of value, they will not 
independently determine the Company's success, which depends in large part 
upon its engineering skills and proprietary manufacturing processes. There 
can be no assurance that any patent issued to the Company will not be 
challenged, invalidated, circumvented or infringed or that the rights granted 
thereunder will provide adequate protection to the Company's technology. 
Within the Company, intellectual property protection of trade secrets is 
achieved through physical security measures at the Company's facilities as 
well as through non-disclosure and non-competition agreements with all 
employees and confidentiality agreements with consultants, strategic 
suppliers and customers. There can be no assurance as to the degree of 
protection afforded by these practices and laws. 

     In addition to the Technology Sharing Agreement and the Patent License 
Agreement with IBM, the Company also has entered into other licensing and 
cross-licensing agreements under the Company's patents and patent 
applications allowing certain competitors to produce certain of the Company's 
products in return for either royalty payments or cross-license rights.

     The Company and certain users of the Company's products have from time 
to time received, and may in the future receive, communications from third 
parties asserting patents against 

                                       11
<PAGE>

the Company or its customers that may relate to certain of the Company's 
manufacturing equipment or products or to products that include the Company's 
products as a component.  Although the Company to date has not been a party 
to any such material intellectual property litigation, certain of its 
customers have been sued on patents having claims closely related to products 
sold by the Company.  In the event that any third party were to make a valid 
infringement claim and a license were not available on terms acceptable to 
the Company, the Company's results of operations could be adversely affected. 
The Company expects that, as the number of patents issued continues to 
increase, and as the Company grows, the volume of intellectual property 
claims could increase.

EMPLOYEES

     As of September 27, 1998, the Company had 7,764 regular employees, 3,827 
of whom were working at the Company's Hutchinson, Minnesota plant, 1,667 of 
whom were working at the Company's Sioux Falls, South Dakota plant, 2,058 of 
whom were working at the Company's Eau Claire, Wisconsin plant, 203 of whom 
were working at the Company's Plymouth, Minnesota plant, and 9 of whom were 
working overseas. The Company's ability to conduct its business would be 
impaired if a significant number of its specialized employees were to leave 
and could not be replaced by comparable personnel. However, turnover of 
specialized employees, including key management personnel, historically has 
been low.  The Company's ability to conduct its business also could be 
impaired if a large number of production employees were to leave and could 
not be replaced.  The locations of the Company's plants and the broad span 
and complexity of technology encompassed by the Company's products and 
processes limit the number of qualified engineering and other candidates for 
key positions. The Company expects that internal training will continue to be 
the primary avenue for the development of key employees. 

     None of the Company's employees is subject to a collective bargaining 
agreement, and the Company has experienced no work stoppages. The Company 
believes that its employee relations are good.

         FLUCTUATIONS IN OPERATING RESULTS

         Our past operating results have fluctuated from fiscal period to 
period. We expect our future operating results also to fluctuate from fiscal 
period to period. These fluctuations may be caused by:

         -    changes in overall demand for our products
         -    changes in our manufacturing process, or problems related to
              implementing a new manufacturing process
         -    introducing new products desired by our industry
         -    changes in the specific products our customers buy
         -    changes in our selling prices
         -    changes in our production capacity, and using our capacity
              efficiently
         -    changes in our infrastructure costs, and how we control them
         -    changes in our manufacturing yields
         -    long disruptions in operations at any of our plants for any reason
         -    changes in the cost of, or limits on, available materials and
              labor
         -    increased costs when we start producing new products, and
              achieving high volume production quickly and profitably

         We typically allow our customers to change or cancel orders without 
penalty up until approximately two weeks before scheduled shipment. We 
therefore plan our production and inventory based primarily on forecasts of 
customer demand. Our forecasts, and customer demand, often fluctuate 
significantly from week to week. Customer demand for and our shipments of 
conventional suspension assemblies decreased significantly during the latter 
part of our fiscal 1997 and throughout all of fiscal 1998, as our major 
customers delayed or cancelled component orders. We believe this reduction 
was due to a slowdown in the disk drive industry's demand for disk drive 
components. We believe the slowdown occurred primarily because:

                                       13
<PAGE>

         -    drive and recording head manufacturers held excess inventory
         -    server and desk-top system demand was somewhat softer
         -    some major personal computer companies started to use
              build-to-order manufacturing, which decreased their required
              disk drive inventory levels
         -    data density improvements reduced slightly the average number of
              suspensions required per drive (from slightly over 5 to
              approximately 4.8 suspensions)

         Our operating results were adversely affected by this slowdown. We 
believe shipments of conventional suspensions in fiscal 1999 will trail those 
of fiscal 1998 as customer demand shifts towards TSA suspension assemblies. 
If customer demand for suspension assemblies weakens, or if one or more 
customers reduce, delay or cancel orders, our business, financial condition 
and results of operations could be materially adversely affected.

         Our gross margins have fluctuated and will continue to fluctuate 
from fiscal period to period. These fluctuations may be caused by:

         -    whether we use our capacity efficiently
         -    changes in overall demand for our products
         -    changes in the specific products our customers buy
         -    changes in our selling prices
         -    changes in our manufacturing yields
         -    increased costs when we start producing new products
         -    changes in the cost of, or limits on, available materials

         We rapidly expanded our TSA suspension production capacity in fiscal 
1998, but our high-volume production of TSA suspensions was not profitable in 
that fiscal year. Our production inefficiencies resulted in significantly 
lower gross margins, which adversely affected our operating results.

         Our selling prices are subject to pricing pressure from our 
customers and market pressure from our competitors. Our selling prices change 
if our pricing strategies change. Our selling prices also are affected by 
changes in overall demand for our products, changes in the specific products 
our customers buy and a product's life cycle. A typical life cycle for our 
products begins with higher pricing when a product is introduced, decreasing 
prices when it is mature, and slightly increasing pricing as it is phased 
out. To offset price decreases during a product's life, we rely primarily on 
higher sales volume. We also rely on improving our manufacturing yield to 
reduce the cost of manufacturing our mature products. If we cannot reduce our 
manufacturing costs during a product's life cycle, or at all, our business, 
financial condition and results of operations could be materially adversely 
affected.

         Many of our products are shipped overseas, specifically to the 
Pacific Rim region. The revenue we earn from these products qualifies for 
favorable tax treatment due to our Foreign Sales Corporation. If we stop 
shipping products overseas, or if the tax laws change to eliminate the tax 
benefits of having a Foreign Sales Corporation, the Company's business, 
financial condition and results of operations could be materially adversely 
affected.

         DEPENDENCE ON HARD DISK DRIVE INDUSTRY

         Almost all of our sales depend on the hard disk drive industry. 
Sales of suspension assemblies accounted for 96% of our net sales in fiscal 
1998, 99% of our net sales in fiscal 1997 and 98% of our net sales in fiscal 
1996. The hard disk drive industry is intensely competitive and our 
technology changes rapidly. The industry's demand for components also 
fluctuates. The hard disk drive industry is highly cyclical, with periods of 
increased demand and rapid growth followed by periods of oversupply and 
subsequent contraction. These cycles may affect suppliers to this industry 
because hard disk drive manufacturers tend to order more components than they 
may need during growth periods, and sharply reduce orders for components 
during periods of contraction. Our results of operations have been adversely 
affected at various times during hard disk drive industry slowdowns, as they 
were in the latter part of fiscal 1997 and throughout all of fiscal 1998. Our 
results of operations could be materially adversely affected if the recent 
slowdown continues or a future significant slowdown in the industry occurs.

         PRODUCT DEVELOPMENT AND INTRODUCTION

         Our continued success depends on our ability to develop and rapidly 
bring to volume production new product platforms and new products that meet 
increasingly higher performance specifications.

         A number of risks are inherent in this process. Increasingly higher 
performance specifications, as well as transitions to new product platforms, 
initially can lower our overall manufacturing yields and efficiencies. This 
in turn can cause product shipments to be delayed or missed. Higher 
manufacturing costs also may be incurred. Manufacturing processes may need to 
be changed or new processes developed. If processes change, equipment may 
need to be replaced, modified or designed, built and installed. These changes 
may require additional capital.

         We may need to increase our research and development and engineering 
expenses to support technological advances and to introduce and manufacture 
new products. We expect these expenses to increase for the following new 
products:

         -    suspensions that incorporate second stage actuators to improve
              head positioning over increasingly tighter data tracks on each
              disk
         -    suspensions on which a preamplifier may be mounted to improve data
              transfer signals from the disk
         -    suspensions for use with new smaller-sized femto heads

                                      15
<PAGE>

         -    suspensions with higher performance specifications than our
              customers currently require

         If we fail to introduce successfully new products on a regular and 
timely basis, demand for our existing products could decline, and our 
business, financial condition and results of operations could be materially 
adversely affected. If a competitor introduced a new suspension assembly 
design, we may not be able to respond to the new design effectively. If the 
new design was widely accepted by the disk drive industry, our business, 
financial condition and results of operations could be materially adversely 
affected.

         We have invested substantial amounts of financial, management, 
engineering and manufacturing resources to develop and introduce our TSA 
suspension assemblies. If continuing market acceptance and/or production of 
our TSA suspension assemblies is delayed for any reason or if widespread 
market acceptance of the TSA product platform is not achieved, our business, 
financial condition and results of operations could be materially adversely 
affected. Furthermore, if we fail to complete the transition to profitable 
high-volume production of our TSA suspension products or determine that TSA 
suspension assemblies cannot be produced profitably in the quantities and to 
the specifications required by our customers, our business, financial 
condition and results of operations could be materially adversely affected.

         We must qualify our products with our customers. The qualification 
process for disk drive products can be complex and difficult. Our management 
cannot be sure that our TSA suspensions will continue to be selected for 
design into our customers' products. If we are unable to obtain additional 
customer qualifications, or if we cannot qualify our products for high-volume 
production quantities, or at all, our business, financial condition and 
results of operations could be materially adversely affected.

         We are developing products for the medical devices market. We have 
developed a monitor that measures tissue oxygen saturation. This monitor 
recently received FDA clearance for marketing in the U.S. The monitor is now 
the subject of clinical trials at several hospitals. Our research and 
development expenses allocated to medical devices were approximately 
$3,190,000 in fiscal 1998, $2,725,000 in fiscal 1997 and $1,990,000 in fiscal 
1996. Our efforts, however, may not result in marketable products. Even if we 
are able to generate marketable products, they may not generate significant 
revenue.

         CAPITAL NEEDS; ANTICIPATED MARKET GROWTH

         We believe that we will need significant funds over the next several 
years to achieve our long-term strategic objectives, and to maintain and 
enhance our competitive position. These funds will be used for capital 
expenditures, research and development, working capital and debt service. Our 
business is highly capital intensive. We require particularly high levels of 
capital expenditures as we move from conventional suspension assembly 
production to high-volume TSA suspension production. We have made substantial 
investments in sophisticated manufacturing technologies and automated 
production equipment for our suspension assemblies. We have added significant 
manufacturing capacity that has increased our fixed costs over the past two 
fiscal years. We have


                                      16
<PAGE>

constructed plants in Eau Claire, Wisconsin and Sioux Falls, South Dakota and 
expanded our plant in Hutchinson, Minnesota. Our total capital expenditures 
were approximately $83,000,000 in fiscal 1997 and $207,000,000 in fiscal 
1998. We also entered into operating leases for production and other 
equipment with costs of approximately $29,000,000 in fiscal 1997 and 
$47,000,000 in fiscal 1998. We currently anticipate spending approximately 
$170,000,000 during fiscal 1999 to expand TSA suspension production capacity. 
We anticipate that we will continue to make significant capital expenditures 
in fiscal 2000 and beyond to further expand TSA suspension production 
capacity. We also will need to continue to invest in new technologies, 
production capacity and infrastructure to accommodate anticipated market 
growth. Any inability to obtain funds in the future could delay or change our 
plans. If we are unable to obtain funds, we may have to curtail our capital 
expenditures, slow plant construction and expansion, and reduce research and 
development expenditures. These delays or changes in our plans could 
materially adversely affect the Company's business, financial condition and 
results of operations.

         We have at times increased our production capacity and the overhead 
that supports production based on anticipated market demand. Anticipated 
market demand, however, has not always developed as rapidly as expected. As a 
result, we have periodically underutilized our capacity. This underutilization 
has at times decreased our profitability. The following factors complicate 
accurate capacity planning for market demand:

         -    the pace of technological change
         -    variability in our manufacturing yields
         -    long lead times for most of our plant and equipment expenditures,
              requiring major financial commitments well in advance of actual
              production requirements

Our failure to plan our capacity requirements accurately, or our failure to 
put in place the technologies and capacity necessary to meet market demand, 
could adversely affect our business, financial condition and results of 
operations.

         Our ability to execute our long-term strategy may depend to a 
significant degree on our ability to obtain additional long-term debt and 
equity capital. We have no commitments for additional borrowings or for sales 
of equity. We cannot determine the precise amount and timing of our funding 
needs at this time. We may be unable to obtain any such future additional 
financing on terms acceptable to us or at all. We may need to refinance our 
indebtedness to repay it at maturity. We may need to obtain additional 
capital on favorable terms to refinance our indebtedness. The following 
factors could affect our ability to obtain additional financing on favorable 
terms, or at all:

         -    changes in interest rates
         -    general economic conditions and conditions in the disk drive
              industry
         -    the perception in the capital markets of our business
         -    our results of operations
         -    our ratio of debt to equity
         -    our financial condition
         -    our business prospects

In addition, certain covenants relating to our existing indebtedness limit our
ability to incur additional indebtedness. If we are unable to obtain sufficient
capital in the future, we may have to curtail our capital expenditures,
slow plant construction and expansion, and reduce research and 

                                      17
<PAGE>

development expenditures. Any such actions could have a material adverse 
effect on our business, financial condition and results of operations.

         MANUFACTURING RISKS

         We manufacture a wide variety of suspension assemblies with 
different selling prices and manufacturing costs. Our product mix varies 
weekly as market demand changes. Any substantial variation in product mix can 
lead to changes in utilization of our equipment and tooling, inventory 
obsolescence and overstaffing in certain areas, all of which could adversely 
impact our business, financial condition and results of operation.

         Rapid technological change in the disk drive industry has led to 
numerous suspension assembly design changes and tighter performance 
specifications. The resulting suspension assemblies initially are more 
difficult to manufacture and typically require additional capital 
expenditures and increased development and support expenses. Manufacturing 
yields and efficiencies also vary from product to product. Newer products 
typically have lower initial manufacturing yields and efficiencies as we 
commence volume manufacturing and thereafter ramp to full production.

         Our TSA suspension assembly production moved from pre-production 
volumes in fiscal 1997, when we shipped 8 million TSA suspensions, to 
production volumes in fiscal 1998, when we shipped 85 million TSA 
suspensions. During fiscal 1998, we did not produce TSA suspensions 
profitably as we ramped to high-volume production. At the end of the fiscal 
1998 fourth quarter, however, we produced TSA suspensions at positive gross 
margins. We cannot be sure that we will attain our output goals and be 
profitable with regard to TSA suspension products.

         As we grow, we may need to transfer production of certain suspension 
assemblies from one manufacturing site to another. In the past, such 
transfers have lowered initial yields and/or manufacturing efficiencies. This 
results in higher manufacturing costs. Our manufacturing plants are located 
in Minnesota, South Dakota and Wisconsin, all of which can experience severe 
weather. Severe weather has, at times, resulted in lower production and 
decreased our shipments.

         Our ability to conduct business would be impaired if our work force 
were to be unionized or if a significant number of our specialized employees 
were to leave and could not be replaced by comparable personnel. The 
locations of our plants and the broad span and technological complexity of 
our products and processes limit the number of satisfactory engineering and 
other candidates for key positions.

         Our production processes require us to store, use and dispose of 
chemicals that are considered hazardous under applicable federal and state 
laws. We must handle these chemicals in accordance with a variety of 
regulatory requirements. If an accident occurred and resulted in significant 
personal injury or environmental damage, our business, financial condition 
and results of operations could be materially adversely affected.

         CUSTOMER CONCENTRATION

         Our sales are concentrated in a small customer base. Although we supply
nearly all domestic and many foreign-based manufacturers of hard disk drives,
and manufacturers of recording heads used in hard disk drives, sales to our five
largest customers constituted 84% of net sales for fiscal 1998, 86% of net sales
for fiscal 1997, and 87% of net sales for fiscal 1996. Over the years, the disk
drive industry has experienced numerous consolidations. This has resulted in
fewer, but larger, 

                                      18

customers for our products. The loss of one or more of our major customers 
for any reason, including the development by any one customer of the 
capability to produce suspension assembles in high volume for their own 
products, or the failure of a customer to pay their account balance with us, 
could have a material adverse effect on our results of operations.

         INTELLECTUAL PROPERTIES

         We attempt to protect our intellectual property rights through 
patents, copyrights, trade secrets and other measures. We may not, however, 
be able to protect our technology adequately. In addition, competitors may be 
able to develop similar technology independently. Our success depends in 
large part on trade secrets relating to our proprietary manufacturing 
processes. We seek to protect these trade secrets and our other proprietary 
technology in part by requiring each of our employees to enter into 
non-disclosure and non-competition agreements. In these agreements, the 
employee agrees to maintain the confidentiality of all of our proprietary 
information and, subject to certain exceptions, to assign to us all rights in 
any proprietary information or technology made or contributed by the employee 
during his or her employment. In addition, we regularly enter into 
non-disclosure agreements with third parties, such as consultants, suppliers 
and customers. These agreements may, however, be breached, and we may not 
have an adequate remedies for any such breach. In addition, our competitors 
may otherwise learn or independently develop our trade secrets.

         We believe that the patents we hold and may obtain are valuable, but 
that they will not independently determine our success. Moreover, patents may 
not be issued for our pending patent applications, and our issued patents may 
not be broad enough to protect our technology. We compete in an industry with 
rapid development and technological innovation. We cannot be sure that our 
future technology will be protectable, or that any patent issued to us will 
not be challenged, invalidated, circumvented or infringed. In addition, we 
have only limited patent rights outside the United States, and the laws of 
certain foreign countries may not protect our intellectual property rights to 
the same extent as do the laws of the United States.

         We and certain users of our products have received, and may receive, 
communications from third parties asserting patents against us or our 
customers that may relate to our manufacturing equipment or to our products 
or to products that include our products as a component. We have not been a 
party to any such material intellectual property litigation to date. Certain 
of our customers, however, have been sued on patents having claims closely 
related to products we sell. If any third party makes a valid infringement 
claim against us and a license were not available on terms acceptable to us, 
our business, financial condition and results of operations could be 
adversely affected. We expect that, as the number of patents issued continues 
to increase, and as we grow, the volume of intellectual property claims made 
against us could increase. We may need to engage in litigation to

         -    enforce patents issued or licensed to us
         -    protect trade secrets or know-how owned by us
         -    determine the enforceability, scope and validity of the
              intellectual property rights of others

We could incur substantial costs in such litigation or other similar legal 
actions, which could have a material adverse effect on our business, 
financial condition and results of operations.

         COMPETITION

         We believe certain of our customers are considering development of 
or are using wireless interconnection technologies that compete with our TSA 
suspension assemblies. Our management cannot be sure that our customers will 
accept TSA suspensions instead of alternative wireless interconnection 
technologies, such as deposition circuitry and flexible circuitry. If our 
customers accept technologies that compete with TSA suspensions, our 
business, financial condition and results of operations may be potentially 
adversely affected.

                                      19
<PAGE>

         Future technological innovations may reduce demand for disk drives. 
Data storage alternatives that compete with disk drive-based data storage do 
exist. These storage alternatives include semiconductor (flash) memory, tape 
memory and laser (optical and CD) drives. The current core technology for 
hard disk drive data storage has been the dominant technology in the industry 
for many years. This technology could be replaced by an alternate technology 
in the future. Our business, financial condition and results of operations 
could be materially adversely affected if technology is adopted by the 
computer industry that replaces disk drives as a computer data storage medium.

         We currently can obtain certain types of photoresist, a liquid 
compound used in the photoetching process, and the stainless steel, copper 
and polyimide materials that meet our strict specifications from only one 
supplier of each such material. The supplier of stainless steel periodically 
resets the price of the product we purchase based on fluctuations in the 
value of the Japanese yen. When it does so, our costs for raw materials may 
increase. If we could not obtain the materials referred to above in the 
necessary quantities, with the necessary quality and at reasonable prices, 
our business, financial condition and results of operations could be 
materially adversely affected.

         VOLATILITY OF SECURITIES

         The securities of companies in the disk drive industry (including 
our securities) generally have volatile market prices. If our revenue or 
earnings in any fiscal quarter fail to meet the investment community's 
expectations, the market price of our securities could fall. In addition, the 
market for our securities has experienced significant price and volume 
fluctuations that are unrelated to our operating results. Future 
announcements about us and general market conditions may affect the market 
price of our securities significantly. Future trading prices of our 
securities may depend on factors beyond our influence such as perceptions of 
our business and the disk drive industry generally, prevailing interest rates 
and the market for similar securities. The volatility of market prices for 
our securities may limit our ability in the future to raise additional 
capital.

         INCREASED LEVERAGE; ABILITY TO SERVICE DEBT

         We incurred $150,000,000 in additional indebtedness in connection 
with the sale of our 6% Convertible Subordinated Notes due 2005 in March 
1998. The additional indebtedness increased our ratio of total debt to total 
capitalization from 21.7% at September 28, 1997 to 48.5% at September 27, 
1998. Our obligations to pay interest increased substantially as a result of 
this increased debt. Our ability to satisfy our obligations to pay interest 
and to repay the debt will be dependent on our future performance. Our
performance is subject to prevailing economic conditions and financial, 
business and other factors, including factors beyond our control. To the 
extent that a substantial portion of our cash flow from operations is used to 
pay the principal of, and interest on, our indebtedness, such cash flow will 
not be available to fund future operations and capital expenditures. Our 
increased debt level also may limit our ability to obtain additional 
financing to fund future capital expenditures, research and development, 
working capital, debt service and other general corporate requirements. It 
could also make us more vulnerable to general economic downturns and 
competitive pressures. We cannot be sure that our operating cash flow will be 
sufficient to fund our future capital expenditure and debt service 
requirements or to fund future operations.

                                      20

<PAGE>

         RESTRICTIVE COVENANTS

         We have entered into a number of financing agreements that contain 
restrictive financial covenants. These covenants require us to maintain cash 
availability and to meet certain minimum financial ratios, including, in 
certain cases, fixed charge coverage, interest coverage and total debt to 
total capitalization ratios. Effective September 27, 1998 we were in 
compliance with all such covenants. Our ability to comply with these 
covenants depends upon our future operating performance. Our future operating 
performance depends, in part, on general industry conditions and other 
factors beyond our control. We cannot be sure that we will be able to comply 
with these covenants. If we fail to comply with these covenants in the 
future, we may not be successful in renegotiating the financing agreements or 
otherwise obtaining relief from the covenants. If we default under some or 
all of the financing agreements, our lenders may require that we immediately 
repay the full outstanding amount we owe to them. In such event, we may have 
to pursue alternative financing arrangements. If we are not in compliance 
with financial covenants in our financing agreements at the end of any fiscal 
quarter, our future results of operations and liquidity could be materially 
adversely affected.

         YEAR 2000 ISSUES

         Certain of our business systems may require updating to continue to 
function properly beyond 1999. We believe that we have allocated adequate 
resources for this purpose and we do not expect to incur significant expenses 
to address this issue. We may not identify all Year 2000 compliance problems 
in our systems before they occur, however, or we may not be able to remedy 
successfully any problems that we do discover. The expenses of our efforts to 
address such problems, or the expenses or liabilities to which we may become 
subject as a result of such problems, could have a material adverse effect on 
our business, financial condition and results of operations. In addition, the 
revenue stream and financial stability of our customers may be adversely 
impacted by Year 2000 compliance problems, which could cause fluctuations in 
our revenue and operating results.  See our discussion of the year 2000 issue 
included in "Management's Discussion and Analysis of Financial Condition and 
Results of Operations" (incorporated by reference in this Annual Report on 
Form 10-K).

ITEM 3.   LEGAL PROCEEDINGS

     On February 27, 1998, the Company commenced a lawsuit, in McLeod County 
District Court in Glencoe, Minnesota, against five former employees and their 
newly-formed company. The lawsuit alleges, among other things, breach of 
non-compete, confidentiality and assignment of inventions agreements.  On 
August 24, 1998, the Court entered an injunction against the defendants.  
Thereafter, the Company filed motions to add a competitor and its parent 
corporation as party defendants, with whom the enjoined defendants had a 
contract.  The parties entered into a Memorandum of Understanding dated 
September 20, 1998, setting forth the material terms of an agreement to 
resolve the litigation.  The parties currently are negotiating a formal 
settlement agreement, consistent with the Memorandum.

     The Company is a party to certain other claims arising in the ordinary 
course of business. In the opinion of management, the outcome of such claims 
will not materially affect the Company's current or future financial position 
or results of operations.

                REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE

To Hutchinson Technology Incorporated:

     We have audited in accordance with generally accepted auditing standards
the consolidated financial statements included in the Hutchinson Technology
Incorporated and Subsidiaries 1998 Annual Report to Shareholders, incorporated
by reference in this Annual Report on Form 10-K, and have issued our report
thereon dated October 29, 1998.  Our audit was made for the purpose of forming
an opinion on those statements taken as a whole.  The schedule listed in
Item 14(a)(2) is the responsibility of the Company's management and is presented
for purposes of complying with the Securities and Exchange Commission's rules
and is not part of the basic consolidated financial statements.  This schedule
has been subjected to the auditing procedures applied in the audit of the basic
consolidated financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic consolidated financial statements taken as a whole.

definition of "Interest Expense" therein, and substituting in lieu thereof the
following::
     
     "INTEREST EXPENSE"  means, for any period of determination, all interest
(without duplication), whether paid in cash or accrued as a liability, on
Indebtedness of the Lessee and its Subsidiaries on a consolidated basis during
such period (including imputed interest on Capitalized Lease Obligations)."
     
     4.   On the date of actual execution of this letter amendment by all
parties hereto, Lessee shall prepay Rent to Lessor, in the aggregate amount of
$2,259,569.31, which prepayment of Rent shall be applied by Lessor upon receipt
and credited as follows:  (a) on the last day of the first fiscal quarter of 
Lessee's fiscal year 2000 following satisfaction by Lessee of the financial
covenants specified in Section XXIV of the Lease in each fiscal quarter of
Lessee's fiscal year 1999, and provided that no Default or event which, with the
giving of notice or the lapse of time, or both, would become a Default has then
occurred and is continuing under the Lease, such prepayment shall be credited in
prepayment of the quarterly installment of Rent

otherwise due under the Lease on such date, or (b) if a default occurs under the
Lease or the conditions specified in clause (a) above are not satisfied, the
amount paid by Lessee to Lessor pursuant to this Section 4 shall be credited in
prepayment of the final installment of Rent otherwise becoming due under the
Lease.
     
     5.   Concurrently with the execution hereof, Lessee shall pay to Lessor a
fee in the amount of $244,863.57 (calculated as one-half of one percent of the
outstanding lease receivables due under the Lease as of September 30, 1998).
     
     6.   RELEASE OF CLAIMS BY LESSEE.   The Lessee represents and warrants that
Lessee is not aware of any claims, counterclaims, setoffs, actions or causes of
actions, damages or liabilities of any kind or nature whatsoever whether at law
or in equity, in contract or in tort, whether now accrued or hereafter maturing
(collectively, "Claims") against Lessor, its direct or indirect parent
corporation or any direct or indirect affiliates of such parent corporation, or
any of their respective directors, officers, employees, agents, attorneys and
legal representatives, or the heirs, administrators, successors or assigns of
any of them (collectively, "Lessor Parties") that directly or indirectly  arise
out of, are based upon or are in any manner connected with any Prior Related
Event (as defined below).  As in inducement to Lessor to enter into this
Amendment, Lessee, and its successors and assigns hereby knowingly and
voluntarily release and discharge all Lessor Parties from any and all Claims,
known to Lessee, that directly or indirectly arise out of, are based upon or are
in any manner connected with any Prior Related Event, other than obligations of
the Lessor Parties under the Master Lease Agreement.  As used herein, the term
"Prior Related Event" means any transaction, event, circumstance, action,
failure to act, occurrence of any sort or type, known to Lessee, which occurred,
existed, was taken, permitted or begun at any time prior to the date of this
Amendment or occurred, existed, was taken, was permitted or begun in accordance
with, pursuant to or by virtue of any of the terms of the Lease or any documents
executed in connection with the Lease or which was related to or connect in any
manner, directly or indirectly to the Lease and all Schedules thereto.

Management's Discussion and Analysis of Results
of Operations and Financial Condition


GENERAL

The Company derives virtually all of its revenue from the sale of suspension 
assemblies to a small number of customers. Suspension assemblies are a 
critical component of hard disk drives and the Company's results of 
operations are highly dependent on the hard disk drive industry. The hard 
disk drive industry is intensely competitive and highly cyclical and the 
Company's results of operations have been adversely affected from time to 
time during hard disk drive industry slowdowns and during the Company's own 
product transitions.

The Company experienced a significant reduction in demand for and shipments 
of its conventional suspension assemblies during the latter part of fiscal 
1997 and throughout all of fiscal 1998. The Company believes this reduction 
was due to a slowdown in the disk drive industry's demand for disk drive 
components, primarily because of excess inventory held by drive and recording 
head manufacturers as a result of softer demand for both servers and personal 
computers. In addition, some of the major personal computer companies 
transitioned to build-to-order manufacturing, decreasing the required disk 
drive inventory levels and improvements in data density have somewhat offset 
the continuing growth in demand for storage. The Company's operating results 
were adversely affected by this slowdown, and consequently have not provided 
the cash needed to help fund capital expenditures that are necessary to meet 
steadily rising demand for the Company's TSA suspension assemblies. The 
Company believes fiscal 1999 shipments of conventional suspensions will 
continue to trail prior year levels as customer demand shifts towards TSA 
suspension assemblies.

The Company's gross margins have fluctuated and will continue to fluctuate 
quarterly and annually based upon a variety of factors such as the level of 
utilization of the Company's production capacity, changes in demand, product 
mix, selling prices and manufacturing yields, increases in production and 
engineering costs associated with production of new products and changes in 
the cost, or limitations in the availability, of materials. Profitable 
high-volume production of TSA suspensions was not achieved by the Company in 
connection with its ramp-up of TSA suspension capacity during fiscal 1998. 
These production inefficiencies resulted in significantly lower gross margins 
which adversely affected operating results. However, positive gross margins 
were achieved on TSA suspension production at the end of the fourth quarter 
of fiscal 1998.

The Company's ability to introduce new products on a timely basis is an 
important factor in its continued success. New products have lower 
manufacturing yields and are produced in lower quantities than more mature 
products. Manufacturing yields generally improve as the product matures and 
production volumes increase. Manufacturing yields also vary depending on the 
complexity and uniqueness of product specifications. Because the Company's 
business is capital intensive and requires a high level of fixed costs, gross 
margins are also extremely sensitive to changes in volume. Small variations 
in capacity utilization or manufacturing yields generally have a significant 
impact on gross margins. The Company typically allows customers to change or 
cancel orders on short notice without penalty. The Company therefore plans 
its production and inventory based primarily on forecasts of customer demand 
rather than on order backlog. Both customer demand and the resulting 
forecasts often fluctuate substantially. These factors, among others, create 
an environment where scheduled production and capacity utilization can vary 
significantly from week to week, leading to variability in gross margins.

                                      17

<PAGE>

Growth in the Company's net sales depends, in part, on the successful 
expansion by the Company of its manufacturing capacity, manufacturing work 
force and corporate infrastructure. In order to meet current and anticipated 
future demand for TSA suspension assemblies, the Company is continuing its 
planned expansion of TSA suspension production capacity. The Company 
currently anticipates spending approximately $170,000,000 in capital 
expenditures during fiscal 1999 primarily for expansion of TSA suspension 
production capacity. The Company anticipates that continued significant 
capital expenditures will be necessary in fiscal 2000 for continued expansion 
of its TSA suspension production capacity and to accommodate anticipated 
market growth. If the Company is not able to finance or complete its current 
expansion plans in a timely manner and within acceptable budgets, its 
quarterly and annual results of operations may be materially adversely 
affected.

MARKET TRENDS

The Company expects that the expanding use of personal computers, enterprise 
computing and storage, increasingly complex software and the emergence of new 
applications for disk storage that have contributed to the historical 
year-to-year increases in disk drive production will continue for the 
foreseeable future. The Company also believes demand for disk drives will 
continue to be subject, as it has in the past, to rapid short-term changes 
resulting from, among other things, changes in disk drive inventory levels, 
responses to competitive price changes and unpredicted high or low market 
acceptance of new drive models.

As in past years, disk drives continue to be the storage device of choice for 
applications requiring low access times and higher capacities because of 
their speed and low cost per megabyte of stored data. The cost of storing 
data on disk drives continues to decrease primarily due to increasing areal 
density, the amount of data which can be stored on magnetic disks. 
Improvements in areal density have been attained by lowering the fly height 
of the read/write head, using smaller read/write heads with advanced air 
bearing designs, improving other components such as motors and media and 
using new read/write head types such as those of magneto-resistive (MR) 
design. The move to MR heads, which require more electrical leads, and the 
transition to smaller or pico-sized heads, which are more sensitive to 
mechanical variation, may compel drive manufacturers to use newer suspension 
technologies, such as the Company's TSA suspension assemblies. Due to growth 
in customer demand for TSA suspensions, the Company expects that TSA 
suspensions will make up approximately half of its shipments in the next 
fiscal year.

The continual pursuit of increasing areal density may lead to further value 
added features for TSA suspensions which incorporate a second stage actuator 
on the suspension to improve head positioning over increasingly tighter data 
tracks, or which mount preamplifiers near the head to improve data transfer 
signals. These changes require the Company to develop the competencies of an 
electromechanical system supplier so that multiple functions may be 
consolidated on the suspension assembly.

The introduction of new types or sizes of read/write heads and new disk drive 
designs tends to initially decrease customers' yields with the result that 
the Company may experience temporary elevations of demand for some types of 
suspension assemblies. The advent of new heads and new drive designs may 
require rapid development and implementation of new suspension types which 
temporarily may reduce the Company's manufacturing yields and efficiencies. 
There can be no assurance that such changes will not continue to affect the 
Company.

The Company generally experiences fluctuating selling prices due to product 
maturity, competitive pricing pressures and new product offerings. While many 
of the Company's current products are reaching or are in the mature phase of 
their life cycle and thus are experiencing declining selling prices, its 
newer products have initially much higher selling prices.

</TABLE>

Net sales for 1998 were $407,616,000, a decrease of $45,616,000 or 10% 
compared to 1997. This decrease was primarily due to decreased suspension 
assembly volume.

Gross loss for 1998 was $3,636,000, compared to a gross profit of 
$117,279,000 for 1997, and gross profit (loss) as a percent of net sales 
decreased from 26% to (1)%. This decrease was primarily due to lower 
conventional suspension assembly sales volume and higher manufacturing costs 
associated with increased TSA suspension assembly production.

Research and development expenses for 1998 were $20,360,000 compared to 
$20,185,000 for 1997. A majority of the research and development expenses 
were used for further TSA product development and for development of the 
Company's medical product.

Selling, general and administrative expenses for 1998 were $41,128,000, a 
decrease of $3,250,000 or 7% compared to 1997. The decreased expenses were 
due primarily to decreased profit sharing and other incentive compensation 
costs of $9,349,000 and decreased recruitment and relocation costs of 
$886,000, partially offset by increased labor expenses of $2,597,000, higher 
depreciation and lease expense of $1,929,000, fees related to certain 
financing agreements of $1,535,000 and higher bad debt provision of 
$1,476,000. As a percent of net sales, selling, general and administrative 
expenses remained at 10%.

Interest expense for 1998 was $4,558,000, an increase of $1,415,000 compared 
to 1997, primarily due to higher average outstanding debt, offset by higher 
capitalization of interest of $3,820,000.

The income tax benefit for 1998 was based on an effective tax rate for the 
year of 26% which was below the statutory federal rate primarily due to tax 
credits and the large portion of sales that qualify for the benefit of the 
Company's Foreign Sales Corporation.

Net loss for 1998 was $48,411,000, compared to net income of $41,909,000 for 
1997. As a percent of net sales, net income decreased from 9% to (12)% 
primarily due to the lower sales volume and higher manufacturing costs, noted 
above.

FISCAL 1997 OPERATIONS

Net sales for 1997 were $453,232,000, an increase of $100,046,000 or 28% 
compared to 1996. This increase was primarily due to increased suspension 
assembly volume.

Gross profit for 1997 was $117,279,000, an increase of $37,709,000 or 47% 
compared to 1996, and gross profit as a percent of net sales increased from 
23% to 26%. This increase was primarily due to higher sales volume and 
improved manufacturing efficiencies.

                                       19

<PAGE>

Research and development expenses for 1997 were $20,185,000 compared to 
$27,651,000 for 1996. The prior year amount includes a $5,500,000 charge 
related to a technology sharing agreement with IBM and higher development 
expenses related to production of TSA prototype suspensions.

Selling, general and administrative expenses for 1997 were $44,378,000, an 
increase of $10,662,000 or 32% compared to 1996. The increased expenses were 
due primarily to increased profit sharing and other incentive compensation 
costs of $7,443,000 and a $1,855,000 increase in labor expenses. As a percent 
of net sales, selling, general and administrative expenses remained at 10%.

Other income, net, for 1997 was $4,143,000, an increase of $2,985,000 
compared to 1996. The increase was primarily due to an increase of $3,631,000 
in interest income as a result of a higher average investment balance, 
partially offset by a $443,000 increase in royalties paid under licensing 
agreements.

Interest expense for 1997 was $3,143,000, an increase of $1,035,000 compared 
to 1996, primarily due to higher average outstanding debt, offset by higher 
capitalization of interest of $1,740,000.

The income tax provision for 1997 was based on an effective tax rate for the 
year of 22% which was below the statutory federal rate primarily due to the 
large portion of sales that qualify for the benefit of the Company's Foreign 
Sales Corporation.

Net income for 1997 was $41,909,000, an increase of $28,107,000 compared to 
1996. As a percent of net sales, net income increased from 4% to 9% primarily 
due to the higher sales volume and improved manufacturing efficiencies, noted 
above.

FISCAL 1996 OPERATIONS

Net sales for 1996 were $353,186,000, an increase of $53,188,000 or 18% 
compared to 1995. This increase was attributable primarily to the Company 
shipping approximately 36% more suspension assemblies during 1996 than 1995, 
partially offset by a lower average selling price due to selling higher 
volumes of lower-priced suspensions.

Gross profit for 1996 was $79,570,000, an increase of $5,807,000 or 8% 
compared to 1995, and gross profit as a percent of net sales decreased from 
25% to 23%. In addition to the sales volumes of lower-priced suspensions 
noted above, the decrease in gross profit as a percent of net sales was also 
due to reduced shipments during the fourth quarter resulting in an increase 
in fixed costs as a percent of sales.

Research and development expenses for 1996 were $27,651,000, an increase of 
$12,610,000 or 84% compared to 1995. The majority of the higher expenses were 
due to increased TSA suspensions development efforts of approximately 
$7,100,000 and a charge of $5,500,000 related to a technology sharing 
agreement with IBM, compared to a $2,500,000 charge for the technology 
sharing agreement during 1995.

Selling, general and administrative expenses for 1996 were $33,716,000, an 
increase of $3,915,000 or 13% compared to 1995. The increased expenses were 
due primarily to an increase in recruitment and relocation expenses of 
$1,722,000, mainly related to the start-up of the Eau Claire assembly 
manufacturing facility, increases in professional services of $1,418,000 and 
labor of $1,141,000, partially offset by reduced profit sharing expenses of 
$1,167,000. As a percentage of net sales, selling, general and administrative 
expenses remained at 10%.

The income tax provision for 1996 was based on an effective tax rate for the 
year of 20% which was below the statutory federal rate primarily due to the 
large portion of sales that qualifies for the benefit of the Company's 
Foreign Sales Corporation.

Net income for 1996 was $13,802,000, a decrease of $7,276,000 compared to 
1995. As a percent of net sales, net income decreased from 7% to 4% primarily 
due to lower gross profit margins, noted above, and increased research and 
development efforts.

LIQUIDITY, CAPITAL RESOURCES AND OTHER MATTERS

The Company's principal sources of liquidity are cash balances, cash flow 
from operations and additional financing capacity. As of September 27, 1998, 
the Company did not have available, and had no commitments for, a revolving 
credit or other similar borrowing facility.

                                      20

<PAGE>

The Company's cash and cash equivalents have fluctuated during fiscal 1998. 
Cash and cash equivalents decreased from $98,340,000 at September 28, 1997 to 
$36,069,000 at December 28, 1997 due to capital expenditures, described 
below, and increased to $160,549,000 at March 29, 1998 as a result of the 
private placement of convertible subordinated notes by the Company, described 
below. Cash and cash equivalents decreased to $107,924,000 at June 28, 1998 
and to $58,942,000 at September 27, 1998 due to continued capital 
expenditures. Cash and cash equivalents decreased by $39,398,000 from 
September 28, 1997 to September 27, 1998 primarily because the capital 
expenditures during the year were greater than the proceeds from the 
convertible subordinated notes and funding from the GE lease receivable, 
described below. The Company used cash from operating activities of 
$12,824,000 in fiscal 1998 and generated cash from operating activities of 
$76,816,000 in fiscal 1997 and $39,904,000 in fiscal 1996.

Cash used for capital expenditures totaled $206,888,000 in fiscal 1998 
compared to $82,639,000 in fiscal 1997 and $77,065,000 in fiscal 1996. The 
expenditures in fiscal 1998 were primarily related to expansion of TSA 
suspension capacity, including manufacturing and support equipment, 
construction costs for the Company's Sioux Falls, South Dakota plant and 
construction of an expansion to the Company's Hutchinson, Minnesota plant. 
The Company currently anticipates spending approximately $170,000,000 during 
fiscal 1999 primarily for expansion of TSA suspension production capacity, 
including manufacturing and support equipment. Financing of these capital 
expenditures will be principally from internally generated funds, cash 
balances and/or additional financing capacity.

In March 1998, the Company issued and sold $150,000,000 aggregate principal 
amount of its 6% Convertible Subordinated Notes due 2005 (the "Convertible 
Notes") to NationsBanc Montgomery Securities LLC and First Chicago Capital 
Markets, Inc., which resold the Convertible Notes to qualified institutional 
buyers and institutional accredited investors. The Company used the net 
proceeds from the issuance and sale of the Convertible Notes primarily to 
fund capital expenditures to expand TSA suspension capacity.

During the first quarter of fiscal 1997, the Company signed a Master Lease 
Agreement with General Electric Capital Corporation ("GE"), providing for 
leasing of up to $25,000,000 of manufacturing equipment in fiscal 1997. The 
Company served as a purchasing agent on behalf of GE. As such, amounts 
expended on GE's behalf, but not yet reimbursed, were included on the 
accompanying consolidated balance sheet under GE lease receivable. During the 
fourth quarter of fiscal 1997, the Company amended the Master Lease 
Agreement, providing for leasing of up to $30,000,000 of manufacturing 
equipment in fiscal 1998. The full fiscal 1997 and 1998 amounts were expended.

The Company's financing agreements contain various restrictive financial 
covenants. Effective September 27, 1998, the Company was in compliance with 
all such covenants. If the Company is not in compliance with financial 
covenants in its financing agreements at the end of any fiscal quarter, its 
future financial results and liquidity could be materially adversely affected.

The Company currently believes its cash balances and cash generated from 
operations will be sufficient to meet its operating expenses, debt service 
requirements and capital expenditures through fiscal 1999, as the Company 
continues to transition from conventional suspension assembly production to 
high-volume TSA suspension assembly production. The Company is evaluating and 
is pursuing additional external sources of capital to supplement its current 
capital resources.

The Company anticipates that continued significant capital expenditures will 
be necessary beyond fiscal 1999 for continued expansion of its TSA suspension 
production capacity, and to accommodate anticipated market growth. In that 
regard, the Company may require significant additional external financing to 
fund operations, debt service and capital expenditures. The Company's ability 
to fund its future liquidity needs depends on its future performance and 
financial results, which, to a certain extent, are subject to general 
conditions in the hard disk drive industry as well as general economic, 
financial, competitive and other factors that are beyond its control. There 
can be no assurance that the Company's business will generate sufficient cash 
flow

                                       21

<PAGE>

from operations, that anticipated revenue growth and operating improvements 
will be realized or that the Company will be able to obtain additional 
financing in an amount sufficient to enable the Company to service its 
indebtedness, make necessary capital expenditures, fund its operations or 
maintain compliance with financing agreement covenants.

In connection with the sale of the Convertible Notes by the Company in March 
1998, the Company incurred $150,000,000 in additional indebtedness which 
increased the ratio of total debt to total capitalization to 48.5% at 
September 27, 1998. As a result of this increased leverage, the Company's 
interest obligations increased substantially. To the extent that a 
substantial portion of the Company's cash flow from operations is used to pay 
the principal of, and interest on, its indebtedness, such cash flow will not 
be available to fund future operations and capital expenditures.

YEAR 2000 ISSUE

The Year 2000 issue is the result of computer programs, microprocessors and 
embedded date reliant systems using two digits rather than four to define the 
applicable year. If not corrected, date-related information and data could 
cause many programs or systems to fail or generate erroneous information. The 
Company's products have no inherent time or date function and will operate 
regardless of Year 2000 issues. The Company, however, uses computer systems 
and programs that will be affected by Year 2000 issues. In fiscal 1997, the 
Company initiated a comprehensive Year 2000 readiness program addressing 
business software and hardware, manufacturing software and hardware used in 
the design, and/or manufacturing of suspension assemblies, and third party 
suppliers. Although the Company does not currently expect any significant 
disruption to its operations due to Year 2000 issues, there can be no 
assurance that the Company will be able to assess, identify and correct all 
Year 2000 issues in a timely or successful manner.

The Company completed remediation in November 1997 of its key business 
software. These key applications include purchased applications that address, 
but are not limited to, sales and order processing, resource planning and 
scheduling, procurement, inventory control, shipping and financial accounting 
and reporting. Additional testing of these systems is being completed during 
fiscal 1999 using "data-aging" software.

The Company completed an enterprise-wide inventory in May 1998 of all other 
business software and hardware with potential Year 2000 issues. The inventory 
includes approximately 460 purchased and internally-developed business and 
desktop software, of which 350 are considered critical by the Company, and 
over 3,000 pieces of hardware, including personal computers, servers and 
network devices. All such critical business and desktop software, and 95% of 
such hardware has been analyzed for the existence and extent of Year 2000 
issues. As of November 23, 1998, approximately 61% of such critical software, 
and approximately 85% of such hardware was Year 2000 compliant. The Company 
believes that all such critical business software and such hardware will be 
Year 2000 compliant by September 1999.

The Company completed an enterprise-wide inventory in May 1998 of all 
manufacturing software, hardware and embedded chip technology with potential 
Year 2000 issues. The inventory includes all equipment and software used to 
design, build and test tools and machines, all tools and machines used to 
design, build and test suspension assemblies, and software and equipment for 
all facility systems. The Company expects analysis of all such inventory for 
the existence and extent of Year 2000 issues to be complete in January 1999. 
As of November 23, 1998, approximately 5% of such manufacturing software, 
hardware and embedded chip technology was Year 2000 compliant. The Company 
believes that all manufacturing software, hardware and embedded chip 
technology will be remediated by September 1999.

The Company is assessing its suppliers whose failure to become Year 2000 
compliant in a timely manner, if at all, could have a material adverse effect 
on the Company. The Company distributed questionnaires on Year 2000

                                       22

<PAGE>

compliance status (and follow-up letters, as necessary) to over 200 of its 
suppliers. The Company currently is reviewing supplier responses and expects 
to initiate follow-up activities in December 1998 to evaluate, or mitigate, 
potential risks associated with such suppliers due to Year 2000 issues.

As of November 23, 1998, the costs incurred by the Company for Year 2000 
compliance efforts have not been material. The Company currently estimates 
incurring an additional $1,500,000 for Year 2000 remediation efforts. The 
projected costs of the Company's Year 2000 compliance efforts are based on 
management's best estimates, which were derived using assumptions about 
future events. These estimates may change as such efforts proceed and actual 
results could differ significantly from current plans.

Although the Company expects to complete its Year 2000 remediation in 1999, 
there are risks if its efforts are delayed or fail. A delay or failure in 
remedying a Year 2000 issue, caused by computer hardware or software errors 
or failures by the Company, or suppliers who may not be Year 2000 compliant 
could, in a worst case, interrupt the Company's business. Depending upon the 
extent and duration of the business interruption resulting from 
non-compliance issues, such interruption could have a material adverse effect 
on the Company's business, financial condition and results of operations.

The Company will begin to develop contingency plans for Year 2000 readiness 
in March 1999 to ensure that back-up processes are in place in the event the 
Company is unable to complete remediation efforts by December 31, 1999. The 
Company expects to complete these contingency plans by September 1999, but 
there is no assurance that the Company will complete such plans or that any 
such plans will address all risks that may actually arise.

OTHER MATTERS

The Company is involved in certain legal matters which may result in 
additional future cash requirements. See the discussion of these matters in 
Note 6, "Commitments and Contingencies," in the notes to the consolidated 
financial statements.

The Company will be subject to certain recent accounting pronouncements. See 
the discussion of these matters in Note 1, "Summary of Significant Accounting 
Policies," in the notes to the consolidated financial statements.

INFLATION

Management believes inflation has not had a material effect on the Company's 
operations or on its financial condition. There can be no assurance, however, 
that the Company's business will not be affected by inflation in the future.

FORWARD-LOOKING STATEMENTS

The statements on pages 3 through 7 of this Annual Report about demand for 
suspension assemblies, including TSA suspensions, anticipated capital 
expenditures, TSA suspension development and production and medical product 
introduction and expenditures, the statements under the headings "General" 
and "Market Trends" about demand for and shipments of disk drives and 
suspension assemblies, including TSA suspensions, manufacturing capacity and 
yields and selling prices, and the statements under the headings "General" 
and "Liquidity, Capital Resources and Other Matters" about anticipated 
operating results, capital expenditures and capital resources, and the 
statements above under the heading "Year 2000 Issues" about Year 2000 
compliance, are forward-looking statements based on current expectations. 
These statements are subject to risks and uncertainties, including slower or 
faster customer acceptance of the Company's new products, difficulties in 
producing its TSA suspensions, difficulties in financing and expanding 
capacity, changes in manufacturing efficiencies, difficulties in implementing 
Year 2000 compliance and the other risks and uncertainties discussed above. 
These factors may cause the Company's actual future results to differ 
materially from historical earnings and from the financial performance of the 
Company presently anticipated.

NOTE 1   Summary of Significant Accounting Policies

         PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
         include the accounts of Hutchinson Technology Incorporated and its
         subsidiaries (the "Company"), all of which are wholly- owned. All
         significant intercompany accounts and transactions have been eliminated
         in consolidation.

         RECLASSIFICATIONS - Certain reclassifications have been made in the
         1997 and 1996 financial statements to conform with the 1998
         presentation. Such reclassifications had no effect on previously
         reported results of operations or shareholders' investment.

         USE OF 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 the
         reported amounts of revenue and expenses during the reporting period.
         Ultimate results could differ from those estimates.

         RECENT ACCOUNTING PRONOUNCEMENTS - In June 1997, the Financial
         Accounting Standards Board ("FASB") released Statement of Financial
         Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
         130"), which requires presentation of comprehensive income on the face
         of the financial statements. Comprehensive income would include such
         items as unrealized holding gains/losses on securities available for
         sale, foreign currency translation adjustments and minimum pension
         liability adjustments. SFAS 130 is effective for fiscal years beginning
         after December 15, 1997. The Company will adopt SFAS 130 during the
         first quarter of fiscal 1999 and anticipates that the effect of
         adopting SFAS 130 will not be significant.

         In June 1997, the FASB released Statement of Financial Accounting
         Standards No. 131, "Disclosures About Segments of an Enterprise and
         Related Information" ("SFAS 131"), which requires reported segments to
         be those used by management to disaggregate a company. SFAS 131 is
         effective for fiscal years beginning after December 15, 1997. The
         Company will adopt SFAS 131 in fiscal 1999 and anticipates that the
         effect of adopting SFAS 131 will not be significant.

         In June 1998, the FASB released Statement of Financial Accounting
         Standards No. 133, "Accounting for Derivative Instruments and Hedging
         Activities" ("SFAS 133"). SFAS 133 establishes accounting and reporting
         standards requiring that every derivative instrument (including certain
         derivative instruments embedded in other contracts) be recorded in the
         balance sheet as either an asset or liability measured at its fair
         value. SFAS 133 requires that changes in the derivative's fair value be
         recognized currently in earnings unless specific hedge accounting
         criteria are met. Special accounting for qualifying hedges allows a
         derivative's gains and losses to offset related results on the hedged
         item in the income statement, and requires that a company must formally
         document, designate and assess the effectiveness of transactions that
         receive hedge accounting. SFAS 133 is effective for fiscal years
         beginning after June 15, 1999. The Company has not yet determined the
         timing of adoption of SFAS 133. While the Company does not expect the
         adoption to materially impact its results of operations or financial
         position, adoption of SFAS 133 could increase volatility in earnings
         for periods subsequent to adoption.

         PROPERTY AND DEPRECIATION - Property, plant and equipment are stated at
         cost. Costs of renewals and betterments are capitalized and
         depreciated. Maintenance and repairs are charged to expense as
         incurred.

         Property is depreciated over an estimated useful life on a
         straight-line basis for financial reporting purposes and is depreciated
         using primarily accelerated methods for tax reporting purposes.
         Estimated useful lives for financial reporting purposes are as follows:

         Buildings                                  25 to 35 years
         Leasehold improvements                      5 to 10 years
         Equipment                                    2 to 8 years

         ENGINEERING AND PROCESS DEVELOPMENT - The Company's engineers and
         technicians are responsible for the implementation of new technologies
         as well as process and product development and improvements.
         Expenditures related to these activities totaled $52,235,000 in 1998,
         $48,204,000 in 1997 and $51,212,000 in 1996. Of these amounts,
         approximately $20,360,000 in 1998, $20,185,000 in 1997 and $27,651,000
         in 1996 are classified as research and development expenses.

         INCOME TAXES - Deferred taxes are provided at currently enacted tax
         rates on all significant temporary differences.

         NET INCOME PER SHARE - The Company adopted Statement of Financial
         Accounting Standards No. 128, "Earnings per Share" ("SFAS No. 128"),
         during the first quarter of fiscal 1998. As a result, all prior periods
         presented have been restated to conform to the provisions of SFAS No.
         128, which requires the presentation of basic and diluted earnings per
         share. Basic earnings (loss) per share is computed by dividing net
         income (loss) available to common shareholders by the weighted average
         number of common shares outstanding during the year. Diluted earnings
         (loss) per share is computed under the treasury stock method and is
         calculated to compute the dilutive effect of potential common shares. A
         reconciliation of these amounts is as follows:

         In March 1998, the Company completed a private placement of
         $150,000,000 aggregate principal amount of 6% Convertible Subordinated
         Notes due 2005 (the "Convertible Notes") with interest payable
         semi-annually commencing September 15, 1998. The Convertible Notes are
         convertible, at the option of the holder, into Common Stock of the
         Company at any time prior to their stated maturity, unless previously
         redeemed or repurchased, at a conversion price of $28.35 per share.
         Beginning March 20, 2001, the Convertible Notes are redeemable, in
         whole or in part, at the option of the Company, at 103.43% of their
         principal amount, and thereafter at prices declining to 100% at any
         time on and after March 15, 2005. In addition, upon the occurrence of
         certain events, each holder of the Convertible Notes may require the
         Company to repurchase all or a portion of such holder's Convertible
         Notes at a purchase price equal to 100% of the principal amount
         thereof, together with accrued and unpaid interest and liquidated
         damages, if any, to the date of the repurchase.

         The Convertible Notes were issued by the Company and were sold in
         transactions exempt from registration under the Securities Act of 1933,
         as amended. The Company filed a Registration Statement registering the
         Convertible Notes and the shares of Common Stock of the Company into
         which the Convertible Notes are convertible.

         On July 26, 1996, the Company completed a $50,000,000 private debt
         placement, of which $25,000,000 was issued as senior unsecured notes,
         having a fixed rate of 7.85%, annual principal payments of $8,333,000
         beginning on July 26, 2001 and maturing July 26, 2003. The Company
         issued an additional $25,000,000 on November 26, 1996 as a senior
         unsecured note having a fixed rate of 8.07%, annual principal payments
         of $4,167,000 beginning on November 26, 2001 and maturing November 26,
         2006.

         The Company's financing agreements contain certain restrictive
         covenants which require the Company, among other things, to maintain
         specified levels of net income, cash and/or cash available from a
         credit facility, working capital, tangible net worth and financial
         ratios, and also impose limitations on capital expenditures, additional
         indebtedness, leases, guarantees, and the payment of dividends.
         Effective September 27, 1998, the Company was in compliance with all
         such covenants.

         Deferred income taxes reflect the net tax effects of temporary
         differences between the carrying amounts of assets and liabilities for
         financial reporting purposes and the amounts used for income tax
         purposes. At September 27, 1998, the Company had unused tax credits and
         net operating loss carryforwards of $21,671,000, of which $5,130,000
         can be carried forward indefinitely and $16,541,000 which expire at
         various dates from 2010 to 2013. A valuation allowance of $15,571,000
         has been recognized to offset the related deferred tax assets due to
         the uncertainty of realizing the benefit of certain tax credits and net
         operating loss carryforwards.

NOTE 4   Fair Value of Financial Instruments

         The following methods and assumptions were used to estimate the fair 
         value of each class of financial instruments for which it is 
         practicable to estimate that value:

         CASH AND CASH EQUIVALENTS - The fair value is based on quoted market 
         prices.

         SECURITIES AVAILABLE FOR SALE - The fair value of these instruments is 
         based on quoted market prices.

         LONG-TERM DEBT - The fair value of the Company's long-term debt is 
         estimated based on the discounted value of the future cash flows 
         expected to be paid on the loans. The discount rate used to estimate 
         the fair value of the loans is the rate currently available to the 
         Company for loans with similar terms and maturities.

         The estimated fair values of the Company's financial instruments are 
         as follows:

NOTE 5   Employee Benefits

         STOCK OPTIONS - The Company has two stock option plans under which up 
         to 6,000,000 common shares are reserved for issuance and of which 
         options representing 3,256,380 common shares have been granted as of 
         September 27, 1998. Options may be granted to any employee, including 
         officers and directors of the Company, and certain non-employees, at 
         a price not less than the fair market value of the Company's common 
         stock at the date the options are granted. Options generally expire 
         ten years from the date of grant or at an earlier date as determined 
         by the committee of the Board of Directors that administers the plans.
         Options granted under the plans generally are exercisable one year 
         from the date of grant.

         The Company follows Accounting Principles Board Opinion No. 25, under 
         which no compensation cost has been recognized in connection with 
         stock option grants pursuant to the stock option plans. Had 
         compensation cost been determined consistent with Statement of 
         Financial Accounting Standards No. 123, "Accounting for Stock-Based 
         Compensation" ("SFAS 123"), the Company's pro forma net income (loss)

         In determining compensation cost pursuant to SFAS 123, the fair value 
         of each option grant is estimated on the date of grant using the 
         Black-Scholes option pricing model with the following weighted 
         average assumptions used for grants during 1998: risk-free interest 
         rate of 5.8%; expected life of six years; and expected volatility of 
         69%. The following weighted average assumptions were used for grants 
         in 1997: risk-free interest rates of 5.85% to 6.25%; expected life 
         of six years; and expected volatility of 68% to 71%. The following 
         weighted average assumptions were used for grants in 1996: risk-free 
         interest rate of 5.6%; expected life of six years; and expected 
         volatility of 73%.

         EMPLOYEE BENEFIT PLANS - The Company has a defined contribution plan 
         covering its employees. The Company's contributions to the plan were 
         $9,239,000 in 1998, $7,762,000 in 1997 and $6,463,000 in 1996.

         The Company sponsors a comprehensive medical and dental plan for 
         qualified employees that is funded by contributions from both the 
         Company and plan participants. Contributions are made through a 
         Voluntary Employee's Benefit Association Trust. The Company 
         recognized expense related to these plans of $19,109,000 in 1998, 
         $15,377,000 in 1997 and $13,439,000 in 1996.

NOTE 6   Commitments and Contingencies

         The Company is committed under various operating lease agreements. 
         Total rent expense under these operating leases was $22,099,000 in 
         1998, $12,487,000 in 1997 and $7,502,000 in 1996. Future minimum

         On May 1, 1996 the Company received $15,300,000 in a sale-leaseback 
         transaction relating to its Eau Claire, Wisconsin assembly 
         manufacturing building. The lease has a term of 15 years.

         During the first quarter of fiscal 1997, the Company signed a Master 
         Lease Agreement with General Electric Capital Corporation ("GE"), 
         providing for leasing of up to $25,000,000 of manufacturing equipment 
         in fiscal 1997. The Company served as a purchasing agent on behalf of 
         GE. As such, amounts expended on GE's behalf, but not yet reimbursed, 
         were included on the accompanying consolidated balance sheet under GE 
         lease receivable. During the fourth quarter of fiscal 1997, the 
         Company amended the Master Lease Agreement, providing for leasing of 
         up to $30,000,000 of manufacturing equipment in fiscal 1998. The full 
         fiscal 1997 and 1998 amounts were expended.

         The Company and certain users of the Company's products have from 
         time to time received, and may in the future receive, communications 
         from third parties asserting patents against the Company or its 
         customers which may relate to certain of the Company's manufacturing 
         equipment or products or to products which include the Company's 
         products as a component. Although the Company to date has not been a 
         party to any such material intellectual property litigation, certain 
         of its customers have been sued on patents having claims closely 
         related to products sold by the Company. In the event any third party 
         were to make a valid infringement claim and a license were not 
         available on terms acceptable to the Company, the Company's operating 
         results could be adversely affected. The Company expects that, as the 
         number of patents issued continues to increase, and as the Company 
         grows, the volume of intellectual property claims could increase.

         On February 27, 1998, the Company commenced a lawsuit, in McLeod County
         District Court in Glencoe, Minnesota, against five former employees and
         their newly-formed company. The lawsuit alleges, among other things,
         breach of non-compete, confidentiality and assignment of inventions
         agreements. On August 24, 1998, the Court entered an injunction against
         the defendants. Thereafter, the Company filed motions to add a
         competitor and its parent corporation as party defendants, with whom
         the enjoined defendants had a contract. The parties entered into a
         Memorandum of Understanding dated September 20, 1998, setting forth the
         material terms of an agreement to resolve the litigation. The parties
         currently are negotiating a formal settlement agreement, consistent
         with the Memorandum.

         The Company is a party to certain other claims arising in the ordinary
         course of business. In the opinion of management, the outcome of such
         claims will not materially affect the Company's current or future
         financial position or results of operations.

Report of Independent Public Accountants

         TO HUTCHINSON TECHNOLOGY INCORPORATED:

         We have audited the accompanying consolidated balance sheets of
         Hutchinson Technology Incorporated (a Minnesota corporation) and
         Subsidiaries as of September 27, 1998 and September28, 1997, and the
         related consolidated statements of operations, shareholders' investment
         and cash flows for each of the three years in the period ended
         September 27, 1998. These financial statements are the responsibility
         of the Company's management. Our responsibility is to express an
         opinion on these 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 financial statements referred to above present
         fairly, in all material respects, the financial position of Hutchinson
         Technology Incorporated and Subsidiaries as of September 27, 1998 and
         September 28, 1997, and the results of their operations and their cash
         flows for each of the three years in the period ended September 27,
         1998 in conformity with generally accepted accounting principles.
