                                     PART I


ITEM 1.  BUSINESS

         Komag, Incorporated ("Komag" or the "Company") designs, manufactures
and markets thin-film media ("disks"), the primary storage medium for digital
data in computer hard disk drives. Komag believes it is recognized as the leader
in the thin-film media market. The Company's business strategy relies on the
combination of advanced technology and cost-effective, high-volume manufacturing
to advance its leadership position. The Company believes that the combination of
these two capabilities is a significant competitive advantage and enables the
Company to support its customers' technically advanced, high-volume product
programs. Komag's products address the high-capacity/high-performance segment of
the disk drive market and are used in products such as disk arrays, network file
servers, high-end personal computers and engineering workstations. The Company
manufactures the highest density disks commercially available for primarily 
5 1/4-inch and 3 1/2-inch form factor hard disk drives. The Company was 
organized in 1983 and is incorporated in the State of Delaware.

         The Company's business is subject to risks and uncertainties, a number
of which are discussed under "Risk Factors".

         Increasing demand for digital storage and low-cost, high-performance
hard disk drive products has resulted in strong unit demand for these products.
International Data Corporation ("IDC") forecasts that world-wide disk drive unit
shipments in 1996 will grow 30% over 1995 and that the annual rate of unit
growth will remain high, at about 20%, through 1999. Greater processing power,
more sophisticated operating systems and application software, high-resolution
graphics and larger data bases are among the developments that have required
ever higher performance from disk drives. For example, the first 5 1/4-inch hard
disk drive, introduced in 1980, offered a capacity of five megabytes (one
million bytes is a megabyte or "MB") with a storage density of less than ten
megabits (one million bits is a megabit; eight bits is one byte) per square
inch. Current high-performance 3 1/2-inch drives have capacities of four
gigabytes (one billion bytes is a gigabyte or "GB") with densities typically of
400 to 500 megabits per square inch. Advances in component technology have been
critical to improving the performance and storage capacity of disk drives and
lowering cost per bit stored.

         The Company has capitalized on its technological strength in thin-film
processes and its manufacturing capabilities to achieve the leading market
position in the thin-film media market. The Company's technological strength
stems from knowledge of materials science and an understanding of the interplay
between disks, heads and other drive components. Komag's manufacturing expertise
in thin-film media is evidenced by its history of delivering reliable products
in high volume. Current manufacturing operations are conducted by the Company in
the United States and Malaysia as well as through a joint venture in Japan.
Asahi Komag Co., Ltd. ("AKCL"), a joint venture with Asahi Glass Co., Ltd.
("Asahi Glass") and Vacuum Metallurgical Company, manufactures thin-film media
in Japan. The Company manufactures disk substrates in the U.S. for internal use
through its subsidiary, Komag Material Technologies, Inc. ("KMT"). A 20%
minority interest in KMT is held by Kobe Steel USA Holdings Inc. (together with
Kobe Steel, Ltd. and other affiliated companies, "Kobe").

         The Company has a direct voting interest (less than 20%) in Headway
Technologies, Inc. ("Headway"). Other Headway shareholders include
Hewlett-Packard Company, AKCL, and a U.S. subsidiary of Asahi Glass. Headway is
developing and manufacturing advanced magnetoresistive ("MR") heads for the data
storage industry.

TECHNOLOGY

         Komag manufactures and sells thin-film magnetic media on rigid disk
platters for use in hard disk drives. These drives are used in computer systems
to record, store and retrieve digital information. Inside a disk drive, the
media or disk rotates at speeds of up to 7,200 RPM. The head scans across the
disk as it spins, magnetically recording or reading information. The domains
where each bit of magnetic code is stored are extremely small (now typically 400
to 500 million bits per square inch in high-performance drives) and precisely
placed. The tolerances of the disks and recording heads are extremely demanding
and the interaction between these components is one of the most critical design
aspects in an advanced disk drive.

         The primary factors governing the density of storage achievable on a
disk's surface are (1) the minimum distance at which read/write heads can
reliably pass over the surface of the disk to detect a change in magnetic
polarity when reading from the disk, defined as glide height (measured in
microinches or millionths of an inch), and (2) the strength of the magnetic
field required to change the polarity of a bit of data on the magnetic layer of
a disk when writing, defined as coercivity (measured in oersteds -- "Oe"). The
lower the glide height, the more accurately and reliably the bit can be
retrieved. The higher the coercivity of the media, the smaller the width of the
bit that can be stored. The Company's plating, polishing and texturing processes
result in a uniform surface with relatively few defects which permits the
read/write heads to pass over the disk surface at glide heights of 1.5
microinches. The platinum-cobalt based alloy deposited on the surfaces of
Komag's disks allows high coercivities, low noise and other desirable magnetic
characteristics. The combination of these factors results in more data stored in
a given area on the disk surface.



PRODUCTS, CUSTOMERS AND MARKETING

         Komag's thin-film disk products generally can be classified by size.
The diameter of the disk corresponds roughly with the width of the disk drive.
The Company sells primarily 95 mm and 130 mm disks for 3 1/2-inch and 5 1/4-inch
drives, respectively. Within each of these sizes, Komag offers a range of
coercivities, glide height capabilities, and other parameters to meet specific
customer requirements.

         Komag primarily sells its media products to independent OEM disk drive
manufacturers for incorporation into hard disk drives which are marketed under
the manufacturers' own labels. The Company also currently sells its disks to
computer system manufacturers. The Company works closely with customers as they
design new high-performance disk drives and generally customizes its products
according to customer specifications.

         Net sales to major customers in 1995 were as follows: Seagate
Technology, Inc. ("Seagate") -- 42%, Quantum Corporation ("Quantum") -- 23%,
Hewlett-Packard Company ("Hewlett-Packard") -- 15%, and Western Digital
Corporation ("Western Digital") -- 12%. Sales are generally concentrated in a
small number of customers due to the high volume requirements of the dominant
disk drive manufacturers and their tendency to rely on a few suppliers because
of the close interrelationship between media and disk drive performance. Given
the relatively small number of high-performance disk drive manufacturers, the
Company expects that it will continue its dependence on a very limited number of
customers. Further there have been consolidations among the Company's disk drive
customers, including the recent merger of Seagate and Conner. In addition,
Quantum recently announced that it would cease disk drive production in
Milpitas, California and Penang, Malaysia and contract with its Japanese
manufacturing partner, Matsushita-Kotobuki Electronics Industries, Ltd. ("MKE"),
to manufacture its disk drives. AKCL, the Company's Japanese joint venture, has
an established working relationship with MKE and MKE has remained AKCL's largest
customer for the past several years. The Company's Malaysian subsidiary recently
began shipments to MKE's new Singapore manufacturing facility. However, there
can be no 



                                       4
<PAGE>   5
assurance that MKE will purchase from either Komag or AKCL the unit quantities
of product which the Company previously supplied to Quantum in the U.S. and
Malaysia. See "Risk Factors".

         Sales are made directly to disk drive manufacturers worldwide (except
media sales into Japan) from the Company's U.S. and Malaysian operations. Media
sales to Japan are made solely through AKCL. Media sales to the Far East from
the Company's U.S. and Malaysian operations represented 62%, 54% and 45% of
Komag's net sales in 1995, 1994 and 1993, respectively. All foreign sales are
subject to certain risks common to all export activities, such as government
regulation and the risk of imposition of tariffs or other trade barriers.
Foreign sales must also be licensed by the Office of Export Administration of
the U.S. Department of Commerce.

         The Company's sales are generally made pursuant to purchase orders
rather than long-term contracts. These purchase orders are generally subject to
change or cancellation without significant penalty. At December 31, 1995 the
Company's backlog of purchase orders scheduled for delivery within 90 days
totaled $156.0 million compared to $69.6 million at January 1, 1995. The Company
believes it is a common practice for disk drive manufacturers to place orders in
excess of actual requirements when there is an industry-wide shortage of media
supply (a condition that persisted throughout much of 1995), and these purchase
orders may be changed or canceled by customers on short notice without
significant penalty. Accordingly, the backlog should not be relied upon as
indicative of sales for any future period.


MANUFACTURING

         Komag's manufacturing expertise in thin-film media is evidenced by its
history of delivering reliable products in high volume. Through the utilization
of proprietary processes and techniques, the Company has the capability to
cost-effectively produce advanced disk products that exhibit uniform performance
characteristics. Such uniform performance characteristics enhance the
reliability of the drive products manufactured by the Company's customers. In
addition, these characteristics raise production yields on the customers'
manufacturing lines, which is an important cost consideration in
high-performance disk drives with large component counts. Manufacturing costs
are highly dependent upon the Company's ability to effectively utilize its
installed physical capacity to produce large volumes of products at acceptable
yields. To improve yields and capacity utilization, Komag has adopted formal
continuous improvement programs at all of its worldwide operations. The
Company's media manufacturing facilities throughout the world have obtained ISO
Certification, an internationally recognized quality standard. The process
technologies employed by the Company require substantial capital investment. In
addition, long lead times to install new increments of physical capacity
complicate capacity planning. Historically, the Company has operated at or near
full capacity with favorable manufacturing yields and equipment utilization
rates.

         The manufacture of thin-film sputtered disks is a complex, multi-step
process that converts polished aluminum substrates into finished data storage
media ready for use in a hard disk drive. The process requires the deposition of
extremely thin, uniform layers of metallic film onto a disk substrate. To
achieve this end, the Company uses a vacuum deposition, or sputtering method,
similar to that used to coat semiconductor wafers. The basic process consists of
many interrelated steps which can be grouped into four major categories:

         1. Nickel Alloy Plating of the Substrate: Through a series of chemical
baths polished aluminum substrates are plated with a uniform nickel phosphorus
layer in order to provide support for the magnetic layer.

         2. Polishing, Texturing and Cleaning. During this relatively
labor-intensive process disks are smoothed and cleaned so that the read/write
heads of the disk drives can fly at low and constant levels over the disks.



                                       5
<PAGE>   6
         3. Sputtering and Lube: By a technically demanding vacuum deposition
process, the magnetic layers are successively deposited on the disk and a hard
protective overcoat is applied. After sputtering, a microscopic layer of
lubrication is applied to the disk's surfaces to improve durability and reduce
surface friction.

         4. Glide Test and Certification. In robotically controlled test cells,
disks are first tested for a specified glide height and then certified for
magnetic properties. Based on these test results, disks are graded according to
specific characteristics and sold to customers based upon their specific
performance requirements.

         Most of the critical process steps are conducted in Class 100 or better
clean rooms. From the final cleaning operation forward, disks are handled by
custom designed, and in many cases Company-built, automated equipment to reduce
contamination and enhance process precision. Minute impurities in materials
used, particulate contamination, or other production problems can reduce
production yields and, in extreme cases, result in the prolonged suspension of
production. Although no problems have required prolonged suspension of the
Company's production to date, other manufacturers of thin-film media have
experienced such suspensions, and no assurance can be given that the Company
will not experience manufacturing problems from contamination or other causes in
the future.


PRODUCTION CAPACITY

         The Company currently has 21 production lines installed at its
manufacturing plants in three countries: ten in the United States, six in
Malaysia, and five at its manufacturing joint venture in Japan. The Company
plans to add one additional line at its Penang, Malaysia facility in the second
quarter of 1996, thus utilizing all available space at that plant. The Company
is currently constructing and equipping a new front end manufacturing facility
in the east Malaysian state of Sarawak. This new facility will manufacture
plated, polished substrates that will be subsequently shipped to the Company's
back end manufacturing facilities in the United States and Penang, Malaysia for
completion. Production at this new facility is expected to begin in the first
half of 1996. In addition, due to strong market demand for the Company's disk
products, the Company has committed to further expand its physical production
capacity in the United States, Malaysia and Japan. The Company began
construction of a new 225,000 square-foot back end disk manufacturing plant in
San Jose, California in October 1995 and recently commenced construction of the
structural foundation for a new 275,000 square foot back end disk manufacturing
plant in Penang, Malaysia. These back end plants will utilize plated, polished
substrates to produce finished sputtered disk products. Production at the new
San Jose and Penang plants is expected to begin during the fourth quarter of
1996 and the first quarter of 1997, respectively. Each of these new facilities
is expected to house the equivalent of at least six current production lines.
AKCL began construction of a 225,000 square-foot facility in Thailand for front
end production of thin-film disks in 1995 and expects to begin production at
this site in late 1996.

         Supplementing this new physical capacity, the Company expects that
continued focus on process improvements will result in higher unit output from
both current and planned production lines during 1996, thus leading to increased
effective capacity.

         During the fourth quarter of 1994, the Company began a series of
process improvements designed to support production of future advanced disk
products. The Company believes that these improvements should enhance product
performance and should enable increased unit output through reduced process
cycle times. In order to utilize these process improvements on all of the
Company's sputtering lines, certain older machines are in the process of being
upgraded to a new design. Three U.S. machines were upgraded in 1995 and three
additional machines will be upgraded in 1996. Only one sputtering line has been
or will be out of production at any given time. As a result, one U.S. machine
will be out of 



                                       6
<PAGE>   7
production throughout 1996 as was the case in 1995. Certain older sputtering
lines at the Japanese joint venture have been or will also be upgraded during
1995 and 1996.

         The Company does not expect to sell appreciable quantities of
AKCL-produced media in 1996 due to strong demand for AKCL's products within the
Japanese media market. In the event demand within the Japanese media market
decreases, AKCL-produced media may become available for qualification and resale
by the Company to its customers.


RESEARCH, DEVELOPMENT AND ENGINEERING

         Since its founding, Komag has focused on the development of advanced
thin-film disk designs, as well as the process technologies necessary to produce
these designs. The Company utilizes a full scale sputtering line for pilot
production. In addition, the Board of Directors has recently approved the
construction of a new 178,000 square foot research and development facility
which the Company expects to occupy in the first half of 1997. The Company's
spending and capital investment for R&D are focused on the investigation,
design, development, and testing of more efficient that can be integrated into
manufacturing in a commercially viable manner.

         In 1996 thin-film media development efforts will focus on completing
the development of low-glide, full-surface textured inductive media for contact
recording and full-surface or mechanical zone-textured magnetoresistive ("MR")
media as well as the technical support for the production ramp of these
products. Additional efforts will be placed on the development of laser
zone-textured media for increased recording density in MR applications and on
the development of smooth glass media. Due to the interaction between heads and
disks in these advanced low-glide (less than 1.5 microinches) products, new
mechanical texturing processes are being developed as well as improved cleaning
processes, improved overcoats, and improved corrosion resistant metallic alloys
for the magnetic layers on the disks.

         The Company's expenditures (and percentage of sales) on research,
development and engineering, were $23.8 million (4.6%) in fiscal 1995, $21.3
million (5.4%) in fiscal 1994, and $29.6 million (7.7%) in fiscal year 1993.
Research, development and engineering expenses in 1995 and 1994 were lower than
in 1993 due to the cessation of operations at a former thin-film head
manufacturing joint venture, Dastek, Inc. ("Dastek"). Dastek's research,
development and engineering expenditures amounted to approximately $11.8 million
in 1993.


STRATEGIC ALLIANCES

         The Company has established joint ventures with Asahi Glass and Kobe.
Komag believes these alliances have enhanced the Company's competitive position
by providing research, development, engineering and manufacturing expertise that
reduce costs and technical risks and shorten product development cycles.

         Asahi Komag Co., Ltd. ("AKCL")

         In 1987 the Company formed a partnership (Komag Technology Partners)
with the U.S. subsidiaries of two Japanese companies, Asahi Glass and Vacuum
Metallurgical Company. The partners simultaneously formed a wholly-owned
subsidiary, AKCL, to manufacture and distribute thin-film disks in Japan. Under
the joint venture agreement, the Company contributed technology developed prior
to January 1987, and licensed technology developed after January 1987, to the
extent such technology relates to sputtered thin-film hard disk media, for a 50%
interest in the partnership. The Japanese partners contributed equity capital
aggregating 1.5 billion yen (approximately $11 million). AKCL began



                                       7
<PAGE>   8
commercial production with its first production line in 1988 and added three
more production lines between 1989 and 1991. A fifth production line was added
at its manufacturing facility in Yonezawa, Japan in September 1995. During the
fourth quarter of 1995 the first sputtering line was removed from production for
upgrading to a new design standard, thus offsetting the incremental unit output
from the newly-installed fifth sputtering line. Following the upgrading of its
second sputtering line, AKCL is expected to commence production on all five
lines late in the first half of 1996.

         The terms of the joint venture agreement provide that AKCL may only
sell disks for incorporation into disk drives that are assembled in Japan, with
no limitation on the territory in which AKCL's customers can sell such assembled
disk drive products. The Company has, however, periodically granted AKCL a
limited right to sell its disks outside of Japan. During the term of the joint
venture agreement and for five years thereafter, the Japanese partners and their
affiliates have agreed not to develop, manufacture or sell sputtered media
anywhere in the world other than through the joint venture, and the Company and
its affiliates have agreed not to develop, manufacture or sell such media in
Japan except through the joint venture. Upon the occurrence of certain
terminating events and the subsequent acquisition of AKCL by one or more of the
joint venture partners, the restrictions related to activities of the acquiring
joint venture partner(s) within Japan may lapse.

         Disk sales to AKCL represented less than 1% of the Company's net sales
in 1995, 1994 and 1993. The Company purchased 1% of AKCL's unit output during
1995 compared to approximately 8% and 14% in 1994 and 1993, respectively.
Increased demand within the Japanese thin-film disk market continued to absorb
most of AKCL's production. The Company does not expect to sell appreciable
quantities of AKCL-produced products to U.S. customers in 1996 due to expected
strong demand within the Japanese media market. However, disk sales by the
Company to AKCL for distribution may increase in 1996.

         Komag Material Technology, Inc. ("KMT")

         In 1988 Komag formed a wholly-owned subsidiary, KMT, to secure an
additional stable supply of aluminum substrates of satisfactory quality for the
Company's products. In 1989 Kobe, a leading worldwide supplier of blank aluminum
substrates, purchased a 45% interest in KMT for $1.4 million. In December 1995,
the Company reacquired 25% of the outstanding common stock of KMT by purchasing
shares from Kobe for $6.75 million. The Company's recent purchase raised its
total ownership percentage of KMT to 80%. Under the recent stock purchase and
related agreements, Kobe retained one seat on KMT's Board of Directors.

         Under the new agreements, Kobe will continue to supply substrate blanks
to KMT while the Company will continue to purchase KMT's entire output of
finished substrates. Further, the Company has indicated its intention to
purchase a substantial proportion of its future substrate requirements from
Kobe, a continuation of a past procurement practice. In combination, KMT and
Kobe supply in excess of 85% of the Company's substrate requirements.

         Dastek, Inc. ("Dastek")

         The Company previously supplied thin-film recording heads for hard disk
drives through Dastek, a joint venture with a subsidiary of Asahi Glass. Due to
market changes during 1993 and significant continuing losses, Dastek ceased its
inductive thin-film head operations in mid 1994, sold its equipment at various
public auctions, settled its obligations with its creditors and was legally
dissolved in December 1994.

         Equity Positions Held by Asahi Glass and Kobe in Komag

         Asahi Glass and Kobe each purchased one million shares of newly issued
Common Stock from the Company for $20 million in January 1989 and March 1990,
respectively. In 1992 Asahi Glass transferred



                                       8
<PAGE>   9
ownership of its shares to a U.S. subsidiary of Asahi Glass. Under their
respective stock purchase agreements, Asahi Glass and Kobe each have the right
to purchase additional shares of the Company's Common Stock on the open market
to increase their respective equity interests in the Company to 20%, the right
to maintain their percentage interest in the Company by purchasing their pro
rata shares of any new equity issuance by the Company, and the right to require
the Company to register their shares for resale, either on a demand basis or
concurrent with an offering by the Company. Each stock purchase agreement
further provides that the Company shall use its best efforts to elect a
representative of each investor to the Company's Board of Directors and to
include such representatives on the Nominating Committee of the Board. During
1994 Asahi America and Kobe reduced their ownership positions in the Company by
3,691,568 and 2,573,112 shares, respectively. There were no purchases or sales
of the Company's stock by Asahi Glass or Kobe in 1995 and according to the
Company's stock records at February 23, 1996, Asahi America and Kobe held
2,000,000 and 2,000,002 shares of Common Stock, respectively. Sales of
significant amounts of the security holdings of Asahi Glass and/or Kobe in the
future could adversely affect the market price of the Company's Common Stock.
Any sales by either party, however, would require relinquishment of its
respective seat on the Company's Board of Directors.


COMPETITION

         Current thin-film disk competitors fall into three groups: U.S.
non-captive manufacturers, U.S. captive manufacturers, and Japan-based
manufacturers. Historically, each of these groups has supplied approximately
one-third of the worldwide thin-film disk unit output. Based upon research
conducted by an independent market research firm, the Company believes it is the
leading supplier of thin-film disks, with a market share greater than twice the
size of any of the U.S. non-captive manufacturers or Japan-based manufacturers.
The Company's U.S. non-captive thin-film disk competitors include Akashic
Memories Corporation (a subsidiary of Kubota, Inc.), HMT Technology Corporation
and StorMedia, Inc. Japan-based thin-film disk competitors include Fuji Electric
Company, Ltd., Mitsubishi Kasei Corp., Showa Denko K.K. and HOYA Corporation.
The U.S. captive manufacturers include IBM and OEM drive manufacturers, such as
Seagate and Conner (who have recently merged operations), and Western Digital,
which manufacture disks as a part of their vertical integration programs. To
date, IBM and these OEM drive manufacturers have sold nominal quantities of
disks in the open market. See "Risk Factors -- Competition".


ENVIRONMENTAL REGULATION

         The Company is subject to a variety of regulations in connection with
its operations, and believes that it has obtained all necessary permits for its
operations. The Company uses various industrial hazardous materials, including
metal plating solutions, in its manufacturing processes. Wastes from the
Company's manufacturing processes are either stored in areas with secondary
containment before removal to a disposal site or processed on site and
discharged to the industrial sewer system. In addition, at one of its
facilities, the Company receives industrial waste water from Headway, which
subleases a portion of a building in Milpitas, California directly from the
Company. Under this arrangement, the Company processes this received waste water
together with its own industrial waste water.

         The Company has made investments in upgrading its waste water treatment
facilities to improve the performance and consistency of its waste water
processing. Nonetheless, industrial waste water discharges from the Company and
other businesses located at the southern end of the San Francisco Bay may, in
the future, be subject to more stringent regulations. Failure to comply with
present or future regulations could result in the suspension or cessation of
part or all of the Company's operations. Such regulations could restrict the
Company's ability to expand at its present locations or could require the
Company to acquire costly equipment or incur other significant expenses.

PATENTS AND PROPRIETARY INFORMATION

         Komag holds and has applied for United States and foreign patents
relating to its processes and equipment for manufacturing components and the
resulting components. While possession of patents could present obstacles to the
introduction of new products by competitors and possibly result in
royalty-bearing licenses from third parties, the Company believes that its
success does not depend on the ownership of intellectual property rights, but
rather on its innovative skills, technical competence and marketing abilities.
Accordingly, the patents held and applied for will not constitute any assurance
of the Company's future success.

         The Company regards elements of its equipment designs and processes as
proprietary and confidential and relies upon employee and vendor non-disclosure
agreements and a system of internal safeguards for protection. Despite these
steps for protecting proprietary and confidential information, there is a risk
that competitors may obtain and use such information. Furthermore, the laws of
certain foreign countries in which the Company does business may provide a
lesser degree of protection to the Company's proprietary and confidential
information than provided by the laws of the United States. In addition, the
Company from time to time receives proprietary and confidential information from
vendors, customers, and partners, the use and disclosure of which being governed
by non-disclosure agreements. Through internal communication and the monitoring
of use and disclosure of such information, the Company complies with its
obligations regarding use and non-disclosure. However, despite these efforts,
there is a risk that such information may be used or disclosed in violation of
the Company's obligations of non-disclosure.

         The Company has occasionally received, and may receive in the future,
communications from third parties asserting violation of intellectual rights
alleged to cover certain of the Company's products or manufacturing processes or
equipment. The Company evaluates whether to seek licenses to the rights referred
to in such communications. Although the Company believes that any such licenses
or other rights could be obtained by the Company on terms that would not have a
material adverse effect on the Company, there can be no assurance that this will
be the case.


EMPLOYEES

         As of December 31, 1995 the Company and its consolidated subsidiaries
had 2,915 employees (2,748 of which are regular employees and 167 of which were
employed on a temporary basis), including 2,587 in manufacturing, 202 in
research, development and engineering, and 126 in sales, administrative and
management positions. Of the total 1,091 are employed at offshore facilities.

         The Company believes that its future success will depend in large part
upon its ability to continue to attract, retain and motivate highly skilled and
dedicated employees. None of the Company's employees is represented by a labor
union and the Company has never experienced a work stoppage.


RISKS FACTORS

         The Company's business is subject to a number of risks and
uncertainties. As a result of those risks described below and other risks
presented elsewhere in this report, there can be no assurance that the Company
will continue to be successful or will maintain a leading market position. The
discussion contained in Item 1 -- "Business" and Item 7 -- "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
contain predictions, estimates and other forward-looking statements that involve
a number of risks and uncertainties. While this discussion represents the
Company's current judgment on the risks and future direction of the business,
such risks and uncertainties could cause actual results to differ materially
from any future performance suggested herein. Factors that could cause actual
results to differ include the following: product transitions to next-generation
products; effective utilization 



                                       10
<PAGE>   11
of existing manufacturing facilities; continuation of improved manufacturing
efficiencies; industry supply-demand relationships and related pricing for
high-end disk products; execution of planned capacity additions; and vertical
integration and company consolidation within a limited customer base. The
Company undertakes no obligation to publicly release the result of any revisions
to these forward-looking statements which may be made to reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.

Rapid Technological Change

         The thin-film disk industry has been characterized by rapid
technological developments, increasingly shorter product life cycles, and price
erosion. The Company believes that its future success depends, in large measure,
on its ability to continually improve existing process technologies and to
develop and implement new process technologies in a timely manner. Such
technologies must support cost-effective, high-volume production of thin-film
disks that meet the ever-advancing customer requirements for enhanced magnetic
recording performance.

         Although the Company has a significant, ongoing research and
development effort to advance its process technologies and the resulting
products, there can be no assurance that the Company will be able to develop and
implement such technologies in a timely manner in order to compete effectively
against competitors' products and/or entirely new data storage technologies. The
Company's results of operations would be materially adversely affected if the
Company's efforts to advance its process technologies were not successful or if
the technologies that the Company had chosen not to develop were proven to be
viable competitive alternatives.

         In addition, protection of technology through patents and other forms
of intellectual property rights in technically sophisticated fields is
commonplace. There can be no assurance that others have not or will not perfect
such intellectual property rights and either enforce those rights to prevent the
Company from practicing certain technologies or demand royalty payments from the
Company in return for practicing those technologies, which may have a material
adverse affect on the Company's results of operations. The Company reviews, on a
routine basis, patent issuances in the U.S. and patent applications which are
published in Japan, and became aware of a Japanese patent application which, if
issued in identical form in Japan or, if there exists a corresponding
application in the U.S., if issued in the U.S., could give rise to a claim of
infringement against the Company. While the Company has not investigated this
Japanese patent application in detail, it believes it is unlikely that a valid
patent of sufficient breadth to materially adversely affect the Company's
business will be issued in either Japan or the U.S. However, there can be no
assurance that a broad patent will not issue from this application, which if
asserted against the Company and upheld may apply to a significant portion of
the Company's products and would have a material adverse effect on the Company's
business.

Capacity Expansion and Capital Intensity

         Inasmuch as the Company is operating its disk production lines at or
near full capacity, future sales and earnings growth will depend on the
successful expansion of the Company's manufacturing capacity. The Company plans
to expand capacity by increasing the disk output of its existing production
lines through process improvements and through the installation of new
production lines at existing and new manufacturing facilities. To improve disk
output from existing production lines, the Company strives to reduce process
cycle times, improve manufacturing yields, and increase equipment utilization
rates. Additionally, the Company is upgrading certain older existing production
lines to a new design standard that should enhance the production capabilities
of these older machines. Should the Company's efforts in these areas not produce
the desired results, the Company's rate of growth may be constrained or
curtailed. Furthermore, should the Company experience a deterioration in
manufacturing performance or a delay or unforeseen outcome arising from the
machine upgrade program, the Company's results of operations would be materially
adversely affected.



                                       11
<PAGE>   12
         The Company currently plans to add another production line at its
existing manufacturing plant in Penang, Malaysia during the second quarter of
1996 and additional lines at new back end manufacturing facilities currently
under construction in San Jose (first line during fourth quarter of 1996) and
Penang (first line during first quarter of 1997). Installations of new
production lines at both facilities are expected to occur in 4 to 6 month
intervals. In addition, a new front end manufacturing plant will begin operation
in the second quarter of 1996 in the east Malaysian state of Sarawak. There can
be no assurance that the Company's additional production lines will be installed
as scheduled or will experience the high levels of manufacturing efficiencies
attained by the Company's existing production lines. The Company must attract,
train, motivate and retain highly-trained and dedicated employees, particularly
at the Company's new operations in Sarawak. Manufacturing and other challenges
in connection with the commencement and subsequent expansion of operations in
any location and in particular Sarawak, a business location with limited
experience in advanced manufacturing, could have a material adverse affect on
the Company's results of operations.

         Based upon industry forecasts of continued high growth in demand for
magnetic media, the Company has developed plans to increase its production
capacity under a schedule that is substantially more aggressive than its past
expansion plans. Implementation of this plan entails parallel expansion at
multiple locations rather than serial expansion one location at a time, thus
requiring precise planning. Successful execution of this parallel expansion will
require timely identification and acquisition of appropriate sites, receipt of
requisite approvals, construction and equipping of facilities, recruitment and
retention of a high quality workforce, and achievement of satisfactory
manufacturing results on a scale greater than the Company's prior expansions.

         The Company's capital expenditures totaled $166 million in 1995 and
1996 capital expenditures are planned to increase to $350 million. Due to the
capital intensive nature of the Company's business, the construction and
equipping of new manufacturing facilities requires substantial capital
investment. Further, significant amounts of continuing investment in capital
equipment is required to improve, modify and change existing manufacturing
processes to support rapidly changing process technologies. There can be no
assurance that the Company will be able to properly plan and install capable
plant and equipment to support the manufacturing processes required for advanced
future products in a timely and cost-effective manner due to the long lead times
required to design, construct and install plant and equipment. Further, required
changes in manufacturing processes could obsolete or significantly shorten the
useful lives of substantial amounts of equipment.

         There can be no assurance that the Company will successfully achieve
planned process improvements or successfully manage its aggressive expansion
plan. In addition, should actual demand for the Company's products not meet the
Company's forecast, and not absorb existing or planned additional capacity, the
fixed costs and operating expenses related to unused capacity would have a
material adverse affect on the Company's results of operations.

Dependence on a Limited Number of Customers; Dependence on the Hard Disk Drive
 Industry

         The Company's sales are concentrated in a small number of customers due
to the high-volume requirements of the dominant disk drive manufacturers and
their tendency to rely on a few suppliers because of the close interrelationship
between media performance and disk drive performance. Net sales to major
customers in 1995 were as follows: Seagate -- 42%, Quantum -- 23%,
Hewlett-Packard -- 15%, and Western Digital -- 12%. Given the relatively small
number of high-performance disk drive manufacturers, the Company expects that it
will continue its dependence on a very limited number of customers. Further
there have been consolidations among the Company's disk drive customers,
including the recent merger of Seagate and Conner. In addition, Quantum recently
announced that it would cease disk drive production in Milpitas, California and
Penang, Malaysia and contract with its Japanese manufacturing partner,
Matsushita-Kotobuki Electronics, Industries, Ltd. ("MKE") to manufacture its
disk drives. AKCL, the Company's Japanese joint venture, has an established
working relationship with MKE and MKE has remained AKCL's largest customer for
the past several years. The Company's



                                       12
<PAGE>   13
Malaysian subsidiary recently began shipments to MKE's new Singapore
manufacturing facility. However, there can be no assurance that MKE will
purchase from either Komag or AKCL the unit quantities of product which the
Company previously supplied to Quantum in the U.S. and Malaysia.

         Seagate produces a portion of its disk requirements internally and
Conner produces the majority of its own disk requirements. Prior to their
merger, both Seagate and Conner announced expansions of their disk production
facilities and Seagate has recently announced a long-term purchase commitment
with one of the Company's competitors. Other customers and potential customers
have, or could adopt, similar strategies. Depending on the overall growth in
market demand for disk products, such actions could result in the reduction or
cessation of purchases from the Company, thus materially adversely affecting the
Company's results of operations. Additionally, if one or more of the Company's
customers were to begin selling disks on the open market in direct competition
with the Company, the Company's results of operations could be further adversely
affected.

         The demand for the Company's high-performance thin-film disks depends
upon the demand for hard disk drives and the Company's ability to provide
technically superior products at competitive prices. The high-performance
segment of the hard disk drive market is characterized by short product life
cycles and rapid technological change. Failure by the Company to qualify new
products and/or successfully achieve volume manufacturing of new customer
products could adversely affect the Company's results of operations.
Furthermore, the Company's sales are generally made pursuant to purchase orders
which are subject to cancellation, modification or rescheduling without
significant penalties. There can be no assurance that the Company's current
customers will continue to place orders with the Company, that orders by
existing customers will continue at the levels of previous periods, or that the
Company will be able to obtain orders from new customers.

Capital Needs

         The Company believes that, in order to achieve its long-term expansion
objectives and maintain and enhance its competitive position, it will need
significant additional financial resources over the next several years for
capital expenditures, working capital and research and development. During 1996,
the Company expects to spend approximately $350 million on capital expenditures.
The Company believes that it will be able to fund these expenditures from a
combination of cash flow from operations, funds available from existing and
possibly new bank lines of credit, and existing cash balances. Property, plant
and equipment expenditures in 1997 are expected to be approximately $400 million
and will require significant new capital, thus necessitating additional debt,
equity or other financing. There can be no assurance that such additional funds
will be available to the Company or, if available, will be available on
favorable terms. In addition, the Company may require additional capital for
other purposes. If the Company is unable to obtain sufficient capital, it could
be required to reduce its capital equipment and research and development
expenditures, which could have a material adverse affect on the Company's
results of operations.

Fluctuations in Operating Results

         The Company believes that its future operating results will continue to
be subject to quarterly variations based upon a wide variety of factors,
including the cyclical nature of the hard disk drive industry, the ability to
develop and implement new manufacturing process technologies, the ability to
introduce new products and to achieve cost-effective, high-volume production in
a timely manner, changes in product mix and average selling prices, the
availability and the extent of utilization of the Company's production capacity,
manufacturing yields, prolonged disruptions of operations at any of the
Company's facilities for any reason, changes in the cost of or limitations on
availability of labor, and increases in production and engineering costs
associated with initial production of new product programs.

         Because the thin-film disk industry is capital intensive and requires a
high level of fixed costs, gross margins are also extremely sensitive to changes
in volume. Assuming fixed average selling prices, reductions in manufacturing
efficiency would cause declines in gross margins. Additionally, decreasing



                                       13
<PAGE>   14
demand for the Company's products generally results in reduced average selling
prices and/or low capacity utilization that, in turn, adversely affects gross
margins and operating results. The Company's ability to maintain average selling
prices and gross margins is dependent on its ability to produce, in volume,
products that are differentiated on the basis of technological superiority. In
the second, third and fourth quarters of 1995, the Company achieved high gross
margins as a result of increased manufacturing efficiencies, coupled with strong
market demand for and an industry shortage of 1800 Oe disks. The Company does
not believe that future gross margins are sustainable at the fourth quarter's
record level. The Company expects that the overall average selling price will
likely trend downward from the average selling price in the fourth quarter of
1995 due to a continuing high proportion of 1800 Oe product sales during the
first half of 1996. The transition to higher-priced 2000 Oe products is expected
to commence in the second quarter of 1996 and such products could account for
more than 50% of the Company's sales during the fourth quarter of 1996. In the
event that market supply meets or exceeds demand or the Company is unable to
introduce and ramp to volume production next-generation products in a timely
manner, the Company's operating results would likely be adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".

         Fluctuations in the financial results of AKCL, the Company's
unconsolidated Japanese disk manufacturing joint venture, could also impact the
Company's financial performance. Equity in net income of AKCL contributed 7% of
the Company's 1995 consolidated net income. AKCL is subject to many of the same
types of risks facing the Company. In addition, the equity income derived from
AKCL fluctuates over time due to its dependence on a more limited customer base
(MKE and Fujitsu Ltd. accounted for 72% and 26%, respectively, of AKCL's 1995
net sales), yen/dollar exchange rate fluctuations, and possible further
write-downs by AKCL of its investment in Headway Technologies, Inc.

Risk of Foreign Operations

         In 1995, sales to customers in the Far East, including foreign
subsidiaries of domestic companies, accounted for 62% of the Company's net sales
from its U.S. and Malaysian facilities, and the Company anticipates that
international sales will continue to represent the majority of its net sales.
All of the Company's sales are currently priced in U.S. dollars worldwide.
Certain costs at the Company's foreign manufacturing and marketing operations
are incurred in the local currency. The Company also purchases certain operating
supplies and production equipment from Japanese suppliers in yen denominated
transactions. Accordingly, the Company's operating results are subject to the
risks inherent with international operations, including but not limited to,
compliance with or changes in the law and regulatory requirements of foreign
jurisdictions, fluctuations in exchange rates, tariffs or other barriers,
difficulties in staffing and managing foreign operations, exposure to taxes in
multiple jurisdictions, and transportation delays and interruptions.

         The Company's existing Malaysian manufacturing facility accounted for
33% and 52% of the Company's 1995 consolidated net sales and operating income,
respectively. Prolonged disruption of operations at this facility for any reason
would cause delays in shipments of the Company's products, thus materially
adversely affect the Company's results of operations.

Competition

         The Company's thin-film disk products are used primarily in the
high-capacity segment of the 3 1/2-inch and 5 1/4-inch hard disk drive market,
where product performance, consistent quality and availability, taken together,
are of great competitive importance. To succeed in an industry characterized by
rapid incremental technological developments, the Company must continuously
advance its thin-film technology at a pace consistent with or faster than its
competitors. In addition, the Company must capture a market share position that
will insure a competitive cost structure. The Company believes that its
thin-film manufacturing facility in Penang, Malaysia provides a significant
competitive cost advantage relative to most other thin-film disk manufacturers
that currently operate exclusively in the U.S. and Japan. However, if the
technology involved in the manufacture of thin-film disks does not continue to
advance 



                                       14
<PAGE>   15
rapidly, or if the Company is not able to keep pace with such advances, the
Company may face increased price competition from other manufacturers. Such
competition could materially adversely affect its results of operations.

         Worldwide disk drive shipments grew 30% in 1995 over 1994 and are
projected to grow approximately 30% in 1996 over 1995 according to International
Data Corporation ("IDC"). IDC forecasts that the annual rate of unit growth will
remain high, at about 20%, through 1999. In response to the continuing rapid
growth of the disk drive market and resulting strong demand for thin-film disk
products, a majority of the Company's competitors (both independent disk
manufacturers and vertically-integrated disk drive customers) have announced
substantial plans to increase disk manufacturing capacity. These significant
investments in new disk production capacity, coupled with slower market growth
for data storage, could reduce the number of potential customers and increase
competition for the remaining market. Such conditions could have a material
adverse affect on the Company's results of operations.

Volatility of Stock Price

         The Company's Common Stock has experienced and can be expected to
experience substantial price volatility in response to actual or anticipated
quarterly variations in operating results, announcements of technological
innovations or new products by the Company or its competitors, developments
related to patents or other intellectual property rights, developments in the
Company's relationships with its customers or suppliers, announcements of
alliances, mergers or other relationships by or between the Company's
competitors and/or customers, and other events or factors. In addition, any
shortfall or changes in revenue, gross margins, earnings, or other financial
results from analysts' expectations could cause the price of the Company's
Common Stock to fluctuate significantly. In recent years the stock market in
general has experienced extreme price and volume fluctuations which have
particularly affected the market price of many technology companies and which
have often been unrelated to the operating performance of those companies. These
broad market fluctuations may adversely affect the market price of the Company's
Common Stock. See "Price Range of Common Stock".

Other Risk Factors

         The Company relies on a limited number of suppliers, in some cases a
sole supplier, for certain materials used in its manufacturing processes. These
materials include aluminum substrates, nickel plating solutions, sputtering
target materials, and certain polishing and texturing supplies. These suppliers
work closely with the Company to optimize the Company's production processes.
Although this reliance on a limited number of suppliers, or sole supplier,
entails some risk that the Company's production capacity would be limited if one
or more of such materials were to become unavailable or available in reduced
quantities, the Company believes that the advantages of working closely with
these suppliers outweigh such risks. If such materials should be unavailable for
a significant period of time, the Company's results of operations would be
adversely affected.

         The Company's California manufacturing facilities, its Japanese joint
venture (AKCL), its Japanese supplier of aluminum blanks for substrate
production, other Japanese suppliers of key manufacturing supplies, and its
Japanese supplier of sputtering machines are each located in areas with seismic
activity. The Company has incurred no significant disruptions to its business
due to seismic activity. However, there can be no assurance that seismic
activity or other natural disasters will not result in a prolonged disruption of
production in the future. Such disruptions could have a material adverse affect
on the Company's results of operations.

</TABLE>

         In addition to the facilities listed above, the Company leases other
smaller facilities in California and Singapore. The Company owns approximately 6
acres of undeveloped land adjacent to its Milpitas manufacturing complex.

         The Company is currently constructing and equipping a 275,000 square
foot front end manufacturing plant on a 77-acre site in Kuching, the capital
city of the east Malaysian state of Sarawak. Production from this facility is
scheduled to commence in the first half of 1996. The Company is also
constructing a new 225,000 square foot back end disk manufacturing plant in San
Jose, California under a build-to-suit lease arrangement on a 14-acre parcel and
recently commenced construction of a new 275,000 square foot back end disk
manufacturing plant in Penang, Malaysia on a 18-acre site. The new back end
plants in San Jose and Penang should begin operations in the fourth quarter of
1996 and first quarter of 1997, respectively.

         In January 1996, the Board of Directors approved the construction
(under build-to-suit lease arrangements) of a new 178,000 square foot research
and development building and a new 90,000 square foot administrative building in
San Jose, California. These new buildings will be located on an 18-acre parcel
adjacent to the new San Jose manufacturing plant and will be ready for occupancy
in the first half of 1997.

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

RESULTS OF OPERATIONS

OVERVIEW

         The Company's business is both capital intensive and volume sensitive,
making capacity planning and efficient capacity use imperative. Physical
capacity, utilization of this physical capacity, yields and average unit sales
price constitute the key determinants of the Company's profitability. Of these
key determinants, price and utilization are the most sensitive to changes in
product demand. If capacity and product price are fixed at a given level and
demand is sufficient to support a higher level of output, then increased output
attained through improved utilization rates and higher manufacturing yields will
translate directly into increased sales and improved gross margins.
Alternatively, if demand for the Company's products decreases, falling average
selling prices and lower capacity utilization could adversely affect the results
of the Company's operations.

         The following discussion contains predictions, estimates and other
forward-looking statements that involve a number of risks and uncertainties.
While this discussion represents the Company's current judgment on the future
direction of the business, such risks and uncertainties could cause actual
results to differ materially from any future performance suggested herein.
Factors that could cause actual results to differ include the following: product
transitions to next-generation products; effective utilization of existing
manufacturing facilities; continuation of improved manufacturing efficiencies;
industry supply-demand relationships and related pricing for high-end disk
products; execution of planned capacity additions; and vertical integration and
consolidations within a limited customer base. See "Business - Risk Factors" for
more detailed discussions of the Company's risk factors. The Company undertakes
no obligation to publicly release the result of any revisions to these
forward-looking statements which may be made to reflect events or circumstances
after the date hereof or to reflect the occurrence of unanticipated events.

1995 VS. 1994

Net Sales

         Net sales for 1995 rose to $512.2 million, a 31% increase over the
$392.4 million reported in 1994. The combination of unit sales volume growth and
an increase in the overall average selling price resulted in the substantially
higher net sales. Nearly three-quarters of the improvement in net sales was
attributable to higher unit sales volume in 1995 relative to 1994. The overall
average selling price typically strengthens only as the result of product mix
shifts to higher-priced, more technologically advanced product offerings. Price
reductions for individual product offerings are characteristic of the thin-film
media industry. The Company began a rapid transition to its leading-edge 1800 Oe
product offering in the fourth quarter of 1994. Unit sales of this product
increased to 91% of unit sales volume in the fourth quarter of 1995 from 14% of
unit sales in the fourth quarter of 1994. The higher sales mix of 1800 Oe
product and a favorable pricing environment arising from an industry shortage of
this product allowed the overall average selling price to increase 7% in 1995
relative to 1994. The overall average selling price will likely trend downward
from the average selling price in the fourth quarter of 1995 due to a continuing
high proportion of 1800 Oe product sales during the first half of 1996. The
transition to higher-priced 2000 Oe products is expected to commence in the
second quarter of 1996 and such products could account for more than 50% of the
Company's sales during the fourth quarter of 1996. Any delay in the introduction
of these products could adversely affect the Company's results of operations.



                                       21
<PAGE>   22
         In addition to sales of its internally produced disk products, the
Company resells products manufactured by Asahi Komag Co., Ltd. ("AKCL"), its
Japanese joint venture with Asahi Glass Company, Ltd. Distribution sales of
product manufactured by AKCL decreased to $0.9 million in 1995 from $9.4 million
in 1994. The Company purchased smaller quantities of product from AKCL in 1995
as demand within the Japanese thin-film media market absorbed the majority of
AKCL's capacity. The Company anticipates that distribution sales of
AKCL-produced product to U.S. customers in 1996 will be minimal.

         Increased production volume may occur due to increased physical
capacity (additional production lines) and/or improvements in manufacturing
efficiencies (improved unit output from higher yields, better equipment
utilization or shorter process cycle times). The increase in unit production
volume required to support the increase in unit sales volume for 1995 relative
to 1994 was primarily achieved through the addition of production lines and
improvement in cycle times. Production yields and equipment utilization rates
were relatively unchanged between the years. Shortened process cycle times
accounted for nearly one-half of the increase in unit output in 1995 relative
to 1994. Net physical capacity additions provided the remaining increase in
unit production volume. The Company added one new sputtering machine in each of
January 1994, August 1994, March 1995 and September 1995. As of the end of the
year, the Company had a total of fifteen production lines, ten in the U.S. and
five in Malaysia. In late 1994, the Company began a program to upgrade its
sputtering machines to enhance product capabilities and shorten process cycle
times. The Company expects one U.S. machine will be out of production on a
rotating basis through 1996. The addition of two production lines in the first
and second quarters of 1996 and full use of the two production lines installed
during 1995 throughout 1996, coupled with expected efficiency improvements,
should allow unit output between 1995 and 1996 to grow approximately 35%.

Gross Margin

         The gross margin percentage for 1995 rose to 38.6%, up markedly from
the 32.0% gross margin achieved for 1994. The combination of the rapid
transition to 1800 Oe product in 1995, strong industry demand for this product,
and solid manufacturing performance produced this historically high gross margin
for the Company. The 7% increase in the overall average selling price accounted
for over two-thirds of the gross margin percentage improvement. Additionally,
process cycle time improvements allowed the Company to lower its overall average
unit cost of production despite the inherently higher costs of producing more
technologically advanced 1800 Oe products. The gross margin percentage increased
sequentially in each quarter of 1995 from 31.2% in the first quarter to 42.6% in
the fourth quarter of 1995 as the sales mix of 1800 Oe product increased and
market conditions for advanced thin-film media remained strong. The gross margin
achieved in the fourth quarter of 1995 was well above the Company's targeted
range and the Company anticipates that its quarterly gross margin percentage
will decline toward its targeted range of 33%-38% as the 1996 fiscal year
progresses. Continued focus on process improvement programs designed to increase
production throughput and reduce the overall average unit production cost should
reduce, but not eliminate, the impact of a decreasing overall average selling
price on the Company's gross margin in 1996. In spite of expected sequential
increases in quarterly unit output, reductions in the gross margin percentage
from the level achieved in the fourth quarter of 1995 will likely restrict
sequential earnings growth during 1996. However, the Company believes that its
1996 annual financial performance will compare favorably to that achieved for
fiscal year 1995.

Operating Expenses

         Research and development expenses increased 12% ($2.5 million) in 1995
relative to 1994. The increase was primarily due to development of improved
sputtering processes and next-generation thin-film media products. Selling,
general and administrative ("SG&A") expenses increased $17.5 million in 1995
compared to 1994. The increase was primarily due to a $13.5 million increase in
the provisions for the Company's bonus and profit sharing programs resulting
from the substantially higher operating performance in 1995. Provisions for bad
debt increased $1.5 million between the years. Excluding provisions for bad debt
and the Company's bonus and profit sharing programs, SG&A expenses



                                       22
<PAGE>   23
increased approximately $2.5 million between the years. Increases in
administrative costs required to support the growth in the business accounted
for the majority of the increase.

Interest Income/Expense and Other Income

         Interest income increased $2.5 million (76%) in 1995 relative to 1994.
The increase was due to the combination of higher interest rates and higher
average investment balances in 1995. The Company exited 1995 with $213.7 million
in cash and short-term investments compared to $93.9 million at the end of 1994.
Proceeds from the Company's third public offering in September 1995 and
significant cash flow provided by operations in 1995 allowed the Company to
maintain its higher average investment balances for 1995. Interest expense
decreased $1.1 million (37%) in 1995 compared to 1994 due to a lower average
outstanding debt balance for 1995. The Company repaid all of its existing
outstanding debt in September 1995 and exited the year with no bank debt. Other
income increased $2.1 million in 1995 relative to 1994 primarily due to receipt
of an insurance recovery related to an electrical power disruption at the
Company's Malaysian manufacturing facility.

Income Taxes

         The effective income tax rate for 1995 of 25% was lower than the 1995
combined federal and state statutory rate of 41% and the effective income tax
rate of 30% in 1994 primarily as a result of a tax holiday granted to the
Company's wholly-owned thin-film media operation in Malaysia. Komag USA
(Malaysia) Sdn. ("KMS") has been granted a five-year tax holiday by the
Malaysian government. Assuming the Company fulfills certain commitments under
its license to operate within Malaysia, this tax holiday may be extended for an
additional five-year period by the Malaysian government. The impact of the tax
holiday was to increase net income by approximately $11.5 million ($0.23 per
share) and $6.4 million ($0.14 per share) in 1995 and 1994, respectively. Losses
incurred prior to the commencement of the tax holiday, approximately $6.2
million, are available for carryforward to years following the expiration of the
tax holiday. The Company anticipates that the effective income tax rate for 1996
will decrease as KMS installs one additional sputtering machine in each of the 
first and second quarters of 1996 and generates a larger percentage of the 
Company's consolidated profit than in 1995.

Minority Interest in Consolidated Subsidiary/Equity in Unconsolidated Joint
Venture

         The minority interest in the net income of consolidated subsidiary
during 1995 represented Kobe Steel USA Holdings Inc.'s ("Kobe USA") 45% share of
Komag Material Technology, Inc.'s ("KMT") net income. KMT recorded net income of
$4.3 million and $2.4 million in 1995 and 1994, respectively. On December 28,
1995 the Company increased its ownership interest in KMT from 55% to 80% through
the purchase of KMT shares directly from Kobe USA for $6.75 million. Kobe USA
retained a 20% minority interest investment in KMT.

         The Company records 50% of AKCL's net income as equity in net income of
unconsolidated joint venture. AKCL reported net income of $14.7 million for
1995, up from $11.0 million for 1994. Equity in net income of AKCL contributed
7% of the Company's 1995 consolidated net income. The Company anticipates that
AKCL's equity income will account for a similar percentage of 1996 consolidated
net income. The Company translates AKCL's yen-based income statements to U.S.
dollars at the average exchange rate in effect during the year. The Japanese yen
strengthened approximately 6% in 1995 relative to 1994. AKCL's net income would
have been approximately $13.5 million in 1995 had the yen-based income statement
been translated at the average rate in effect for 1994.

         AKCL's net income in 1996 will be affected by the start-up costs
associated with a new manufacturing facility and the financial performance of
Headway Technologies, Inc. ("Headway"). AKCL began construction of a 225,000
square foot facility in Thailand for front end production of thin-film disks in
1995 and expects to begin production at this site in late 1996. AKCL invested in
Headway in 1994 and has been recording partial writedowns of its investment
based upon net losses incurred at 



                                       23
<PAGE>   24
Headway. AKCL's net income reflected writedowns, net of tax, of $2.2 million and
$0.5 million in 1995 and 1994, respectively. To the extent that such losses
continue, AKCL will record a portion of those losses. Alternatively, AKCL will
record a portion of Headway's net income, if any, to the extent of previously
recognized losses.

Other

         The Company operates facilities in the U.S. and Malaysia and ships
products to both domestic and international locations. In order to minimize the
risks associated with foreign currency fluctuations, the Company denominates its
sales in U.S. dollars and periodically enters into foreign exchange contracts to
hedge firm purchase commitments. The Company had approximately $17.1 million of
foreign exchange contracts outstanding at December 31, 1995. No such foreign
exchange contracts were open as of January 1, 1995. Gains and losses created by
the remeasurement of the financial statements of the Company's Malaysian
operations into U.S. dollars from Malaysian ringgits have not had a significant
effect on the consolidated results of operations.

         In 1995, the Company adopted Statement of Financial Accounting Standard
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed" ("FAS 121"). The adoption of FAS 121 did not have a
material impact on the Company's financial position or results of operations.
Beginning January 1, 1996, the Company will be required to adopt Statement of
Financial Accounting Standard No. 123, "Accounting for Stock-Based Compensation"
("FAS 123"). The Company plans to adopt only the disclosure requirements of the
Statement and, as such, the adoption of FAS 123 will have no impact on the
Company's financial position or results of operations.


1994 VS. 1993

         The Company's consolidated results of operations for 1994 represent the
Company's thin-film media operations exclusively. In contrast, results of
operations for 1993 consolidate the operating results of the Company's thin-film
media operations and Dastek, Inc. ("Dastek"), the Company's thin-film head joint
venture with Asahi Glass America, Inc. ("Asahi America"). In the fourth quarter
of 1993, the Company recorded a $39.0 million restructuring charge related to
the cessation of Dastek's inductive thin-film head operations, which was
effected during 1994. Approximately one-half of the restructuring charge
provided for estimates of losses to be incurred during the 1994 wind down of
Dastek's operations. The remaining charge primarily represented reductions of
assets and liabilities to their estimated net realizable value. Actual operating
losses incurred in 1994 were approximately one-third higher than estimated in
the 1993 restructuring charge. However, net losses from the sale of Dastek's
assets and the settlement of its liabilities were lower by a comparable amount.

         Excluding Dastek's results of operations and the related restructuring
charge, income statements for the Company were as follows for 1994 and 1993:

</TABLE>
 

         The following discussion compares the results of operations for 1994
vs. 1993, excluding the results of Dastek, as presented above.

Net Sales

         Unit sales of thin-film media increased nearly 40% in 1994 relative to
1993. The effect on thin-film media revenue from this substantial increase in
unit sales volume was reduced by a 16% decrease in the overall average unit
selling price between the years. In 1994, the Company began a transition to more
advanced 1800 Oe product offerings. The transition to this new disk product was
more challenging and required more time than previous product transitions. As a
result of the more lengthy product transition time, the effects of traditionally
declining prices for individual product offerings reduced the overall average
selling price between the years. Distribution sales of product manufactured by
AKCL decreased to $9.4 million in 1994 from $17.1 million in 1993. The Company
purchased smaller quantities of product from AKCL in 1994 as demand within the
Japanese thin-film media market absorbed more of AKCL's capacity.

         The increase in unit production volume required to support the increase
in unit sales volume for 1994 relative to 1993 was primarily achieved through a
combination of higher manufacturing throughput, increased physical capacity, and
improved production yields and utilization rates. Improvements in manufacturing
throughput, primarily due to shortened sputter cycle times, and physical
capacity additions each accounted for approximately 40% of the increased unit
production volume. Improvements in yields and utilization rates accounted for
the remaining increase in unit production volume.



                                       25
<PAGE>   26
Gross Margin

         The thin-film media gross margin percentage decreased to 32.0% for 1994
from 32.7% for 1993. Excluding distribution sales of product manufactured by
AKCL for resale to the Company's customers, the gross margin percentage
decreased to 32.7% from 34.1% between the years. The substantial decrease in the
overall average selling price outpaced solid improvements in the average unit
production cost and resulted in the lower gross margin percentage for 1994.
Manufacturing efficiencies, such as reduced cycle times and yield and
utilization improvements, were the primary drivers in reducing the average unit
production cost.

Operating Expenses

         Research, development and engineering expenses increased $3.5 million
in 1994 compared to 1993. The increase between the years was mainly due to
development costs for advanced thin-film media, including costs associated with
the Company's thin-film media pilot production line. Selling, general and
administrative expenses increased $2.6 million in 1994 relative to 1993,
primarily due to higher provisions for the Company's bonus and profit sharing
programs resulting from the higher operating profitability for the Company's
thin-film media operations.

Interest Income/Expense and Other Income

         Interest income increased $0.6 million in 1994 relative to 1993. The
increase was due to the combination of higher interest rates and higher average
investment balances in 1994. Interest expense decreased $1.1 million. In 1993,
the Company reversed previously capitalized interest related to the construction
of its thin-film media manufacturing facility in Malaysia, thus increasing 1993
interest expense. Excluding this reversal, interest expense decreased $0.2
million primarily due to a lower average outstanding debt balance for 1994.
Other income, net decreased $0.6 million in 1994 mainly due to higher losses on
disposal of equipment in 1994 relative to 1993.

Income Taxes

         The effective income tax rate for 1994 of 30% was lower than the
effective income tax rate of 37% in 1993 primarily as a result of a tax holiday
granted to the Company's wholly-owned thin-film media operation in Malaysia.
Komag USA (Malaysia) Sdn. has been granted a five-year tax holiday by the
Malaysian government. The impact of the tax holiday was to increase net income
by approximately $6.4 million ($0.14 per share) in 1994.

Minority Interest in Consolidated Subsidiary/Equity in Unconsolidated Joint
Venture

         The minority interest in the net income of consolidated subsidiary
represented Kobe USA's 45% share of KMT's net income. KMT recorded net income of
$2.4 million and $1.1 million in 1994 and 1993, respectively.

         The equity in net income of unconsolidated joint venture reflected the
Company's 50% interest in AKCL's net income. AKCL reported net sales and net
income of $131.3 million and $11.0 million for 1994, up from $119.4 million and
$9.8 million for 1993. AKCL's functional currency is the Japanese yen. The
Company translates AKCL's yen-based income statements to U.S. dollars at the
average exchange rate in effect for each quarterly period. The Japanese yen
strengthened approximately 8% in 1994 relative to 1993. AKCL's net income would
have been approximately $10.0 million in 1994 had the yen-based income statement
been translated at the average rate in effect for 1993.



                                       26

LIQUIDITY AND CAPITAL RESOURCES

         Consolidated cash and short-term investments of $213.7 million at the
end of 1995 increased substantially from $93.9 million at the end of 1994.
Consolidated operating activities generated $188.8 million in cash during 1995
and more than funded the Company's $166.5 million of capital spending during the
year. Sales of Common Stock under the Company's stock option and stock purchase
programs during 1995 generated $10.8 million, while scheduled repayments of
long-term obligations used $9.7 million. In September 1995, the Company raised
$122.1 million (net of underwriting commissions and expenses) through a public
offering of 3.5 million shares of the Company's Common Stock. The Company used
$19.8 million of the proceeds from the stock offering to repay all of its
long-term debt.

         Total capital expenditures for 1996 are currently planned at
approximately $350 million. Construction and fit up of three new manufacturing
facilities are the major components of the capital plan. The Company is nearing
completion of a 275,000 square foot facility for the front end stages of its
manufacturing process in Sarawak, Malaysia and expects to begin production at
this site in the second quarter of 1996. Two back end factories are currently
under construction in San Jose, California and Penang, Malaysia. The San Jose
factory is approximately 225,000 square feet and the Penang factory is
approximately 275,000 square feet. The Company plans to begin production at the
new San Jose and Penang facilities in late 1996 and early 1997, respectively.
Additionally, the Company expects to begin construction of a 178,000 research
and development facility and a 90,000 square foot administration building in
1996 for occupancy in the first half of 1997. Current noncancellable commitments
total approximately $165.0 million.

         The Company believes that, in order to achieve its long-term expansion
objectives and maintain and enhance its competitive position, it will need
additional financing over the next several years for capital expenditures,
working capital, and research and development. During the two-year period of
1996 and 1997, the Company expects to spend approximately $750 million to
construct new facilities and add production equipment at its new and existing
facilities. Assuming a continued strong operating performance, the Company
expects to fund its 1996 capital expenditures through a combination of cash
flow from operations, its cash balances, and funds available from its
unutilized $140 million credit facilities. However, new debt or equity
financing will likely be required to fund a portion of capital expenditures in
1997. If the Company is unable to obtain sufficient capital it could be
required to reduce its capital equipment and research and development
expenditures which could have a material adverse effect on the Company's
results of operations.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS


The Board of Directors and Stockholders
Komag, Incorporated

         We have audited the accompanying consolidated balance sheets of Komag,
Incorporated as of December 31, 1995 and January 1, 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1995. Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits. We did not audit the financial
statements of Asahi Komag Co., Ltd. (a corporation in which the Company has a
50% interest) as of December 31, 1995 and January 1, 1995, and for each of the
three years in the period ended December 31, 1995. Those financial statements
were audited by other auditors whose reports have been furnished to us, and our
opinion, insofar as it relates to data included for Asahi Komag Co., Ltd. as of
December 31, 1995 and January 1, 1995, and for each of the three years in the
period ended December 31, 1995, is based solely on the report of the other
auditors.

         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 and the report of other auditors provide a reasonable
basis for our opinion.

         In our opinion, based on our audits and the report of other auditors,
the financial statements referred to above present fairly, in all material
respects, the consolidated financial position of Komag, Incorporated at December
31, 1995 and January 1, 1995, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1995, in conformity with generally accepted accounting principles. Also, in our
opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation: The consolidated financial statements include the
accounts of the Company, its wholly-owned and majority-owned subsidiaries (see
Notes 11 and 12) and equity in its unconsolidated joint venture (see Note 13).
All significant intercompany accounts and transactions have been eliminated in
consolidation.

Foreign Currency Translation: The functional currency of the Company's
unconsolidated joint venture is the Japanese yen. Translation adjustments
relating to the translation of these statements are included as a separate
component of stockholders' equity and not included in net income. The functional
currency for the Company's Malaysian operation is the U.S. dollar. Remeasurement
gains and losses, resulting from the process of remeasuring these foreign
currency financial statements into U.S. dollars, are included in operations.

Foreign Exchange Gains and Losses: The Company enters into foreign currency
forward exchange contracts to reduce the impact of currency fluctuations on firm
purchase order commitments for equipment and construction-in-process. Gains and
losses related to these contracts are included in the cost of the assets
acquired. The Company had approximately $17,125,000 in foreign exchange
contracts outstanding at December 31, 1995. The fair market value of these
foreign exchange contracts was not materially different from the contract value
at December 31, 1995. There were no foreign exchange contracts outstanding at
January 1, 1995. The Company had approximately $358,000 and $9,000,000 of
unhedged Japanese yen based firm purchase commitments at December 31, 1995 and
January 1, 1995, respectively.

Cash Equivalents: The Company considers as a cash equivalent any highly liquid
investment that matures within three months of its purchase date.

Short-Term Investments: The Company invests its excess cash in high-quality,
short-term debt instruments. Short-term investments consist primarily of
AAA-rated, municipal auction rate preferred stock. None of the Company's debt
security investments have maturities greater than one year. At December 31, 1995
all short-term investments are designated as available for sale. Interest and
dividends on the investments are included in interest income.

The following is a summary of the Company's investments by major security type
at amortized cost, which approximates fair value:

There were no realized gains or losses on the Company's investments during 1995
as all investments were held to maturity during the year. The Company utilizes
zero-balance accounts and other cash management tools to invest all available
funds including bank balances in excess of book balances.

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

Property, Plant and Equipment: Property, plant and equipment, except
construction-in-process, are stated at cost less accumulated depreciation and
amortization. Depreciation is computed by the straight-line method over the
estimated useful lives of the assets. The estimated useful life of the Company's
buildings is 30 years. Furniture and equipment are generally depreciated over 3
to 5 years and leasehold improvements are amortized over the shorter of the
lease term or the useful life.

Revenue Recognition: The Company records sales upon shipment and provides an
allowance for estimated returns of defective products.

Research and Development: Research and development costs are expensed as
incurred.

Income Taxes: The provision for income taxes is based on pretax financial
accounting income. Deferred tax assets and liabilities are recognized for the
expected tax consequences of temporary differences between the tax and book
basis of assets and liabilities.

Income (Loss) Per Share: Income per share has been computed using the weighted
average number of shares of Common Stock and dilutive common stock equivalents
outstanding during the period. Common stock equivalents include shares issuable
upon the assumed exercise of options reflected under the treasury stock method.
Loss per share has been computed using the weighted average number of shares of
Common Stock outstanding during the period.

Reclassifications: Certain reclassifications have been made to the 1994
Consolidated Balance Sheet, the 1994 and 1993 Statements of Cash Flows, and the
related notes to conform to the current year's presentation.

Fiscal Year: The Company uses a 52-53 week fiscal year ending on the Sunday
closest to December 31. The years ended December 31, 1995, January 1, 1995 and
January 2, 1994 were each comprised of 52 weeks.

Stock Split: The Company effected a two-for-one stock split of its outstanding
Common Stock effective December 21, 1995. Earnings per share and share amounts
for all periods in the consolidated financial statements have been restated to
reflect the split.

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 amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

NOTE 3.  CONCENTRATION OF CUSTOMER AND SUPPLIER RISK

The Company performs ongoing credit evaluations of its customers' financial
conditions and generally requires no collateral. Significant customers accounted
for the following percentages of net sales in 1995, 1994 and 1993:

Conner Peripherals, Inc.           less than 10%  less than 10%             11%
</TABLE>

In February 1996, Seagate and Conner merged. Net sales to Seagate and Conner on
a combined basis were 44%, 40% and 35% in 1995, 1994 and 1993, respectively. In
addition, Quantum recently announced that it would cease disk drive production
in Milpitas, California and Penang, Malaysia and contract with its Japanese
manufacturing partner, Matsushita-Kotobuki Electronics Industries, Ltd. ("MKE")
to manufacture its drives. Asahi Komag Co. Ltd. ("AKCL"), the Company's Japanese
joint venture, has an established working relationship with MKE and MKE has
remained AKCL's largest customer for the past several years. The Company's
Malaysian subsidiary recently began shipments to MKE's new Singapore
manufacturing facility. However, there can be no assurance that MKE will
purchase from either the Company or AKCL the unit quantities of product which
the Company previously supplied to Quantum in the U.S. and Malaysia.

Kobe Steel, Ltd. ("Kobe") supplies aluminum substrate blanks to Komag Material
Technology, Inc. ("KMT"), and the Company in turn purchases KMT's entire output
of finished substrates. The Company also purchases substantial quantities of
finished substrates from Kobe in addition to the substrates purchased from KMT.
In combination, KMT and Kobe supply in excess of 85% of the Company's substrate
requirements. The Company also relies on a limited number of other suppliers, in
some cases a sole supplier, for certain other materials used in its
manufacturing processes. These materials include nickel plating solutions,
sputtering target materials and certain polishing and texturing supplies. These
suppliers work closely with the Company to optimize the Company's production
processes. Although this reliance on a limited number of suppliers, or sole
supplier, entails some risk that the Company's production capacity would be
limited if one or more of such materials were to become unavailable or available
in reduced quantities, the Company believes that the advantages of working
closely with these suppliers outweigh such risks. If such materials should be
unavailable for a significant period of time, the Company's results of
operations would be adversely affected.


NOTE 4.  STOCKHOLDERS' EQUITY

In 1995, the Company raised $122,100,000 from the sale of 3,500,000 shares of
Common Stock in a follow-on public stock offering. In December 1995, the
stockholders approved an increase in the number of shares of Common Stock
authorized for issuance to 85,000,000.

NOTE 5.  STOCK OPTION PLANS AND STOCK PURCHASE PLAN

Under the Company's stock option plans ("Plans"), options to purchase up to
12,760,000 shares of Common Stock may be granted to key employees and directors.
The Plans provide for issuing both incentive stock options, which must be
granted at fair market value at the date of grant, and non-qualified stock
options, which may be granted at not less than 85% of fair market value at the
date of grant. Outstanding options generally vest over four years and expire no
later than ten years from the date of grant. Options may be exercised in
exchange for cash or outstanding shares of the Company's Common Stock.
Approximately 17,000 and 11,000 shares of the Company's Common Stock were
received in exchange for option exercises in 1995 and 1994, respectively. No
such exchange occurred in 1993. At December 31, 1995 approximately 543,000
options were available for grant and 5,571,000 shares of Common Stock were
reserved for future issuance under these Plans. At December 31, 1995 and January
1, 1995 approximately 1,487,000 and 1,283,000, respectively, of the outstanding
options were exercisable.

Under an option plan for employees of Dastek, Inc. ("Dastek"), a former joint
venture of the Company (see Note 11), options to purchase 2,000,000 shares of
the Company's Common Stock were authorized and reserved for issuance. At
December 31, 1995, 560,000 options had been exercised and no options were
exercisable or outstanding under the Dastek plan. No additional options will be
granted under the Dastek plan due to the cessation of Dastek's operations.

A summary of stock option transactions is as follows:

In January 1996 the Company's Board of Directors approved an increase of
3,000,000 in the total number of shares of Common Stock that may be issued under
the Komag Stock Option Plan. The increase is subject to stockholder approval.

Under the terms of the Employee Stock Purchase Plan, employees may elect to
contribute up to 10% of their compensation toward the purchase of shares of the
Company's Common Stock. The purchase price 


                                       40
<PAGE>   41
per share will be the lesser of 85% of the fair market value of the stock on the
first day of enrollment in a twenty-four month offering period or the last day
of each semi-annual period within the twenty-four month offering period. The
total number of shares of stock that may be issued under the Plan cannot exceed
2,800,000 shares. Shares issued under this plan approximated 431,000, 469,000
and 528,000 in 1995, 1994 and 1993, respectively. At December 31, 1995
approximately 398,000 shares of Common Stock were reserved for future issuance
under this Plan.

Beginning January 1, 1996, the Company will be required to adopt Statement of
Financial Accounting Standard No. 123, "Accounting for Stock-Based Compensation"
("FAS 123"). The Company plans to adopt only the disclosure requirements of the
Statement and, as such, the adoption of FAS 123 will have no impact on the
Company's financial position or results of operations.


NOTE 6.  BONUS AND PROFIT SHARING PLANS

The Company and its subsidiaries maintain various cash profit sharing plans.
Under the terms of the cash profit sharing plans, a percentage of semi-annual
operating profit, as defined in the plans, is allocated among all employees who
meet certain criteria. Under the terms of the Company's bonus plans, various
percentages of an operating unit's annual operating profit, as defined in the
respective bonus plans, is paid to eligible employees. The Company expensed
$19,990,000, $9,083,000 and $8,084,000 under these bonus and cash profit sharing
plans in 1995, 1994 and 1993, respectively.

The Company and its subsidiaries maintain savings and deferred profit sharing
plans. Employees who meet certain criteria are eligible to participate. In
addition to voluntary employee contributions to these plans, the Company
contributes four percent of semi-annual consolidated operating profit, as
defined in the plans. These contributions are allocated to all eligible
employees. Furthermore, the Company matches a portion of the employee's
contributions to the plans up to a maximum amount. The Company contributed
$6,653,000, $4,081,000 and $2,207,000 to the plans in 1995, 1994 and 1993,
respectively.

Expenses for the Company's bonus and profit sharing plans are included in
selling, general and administrative expenses.

As of December 31, 1995 a 60%-owned subsidiary of the Company, Dastek Holding
Company, has a federal tax net operating loss carryforward of approximately
$99,000,000. The Company has fully reserved for the potential future federal tax
benefit of this net operating loss in the deferred tax asset 



                                       42
<PAGE>   43
valuation allowance due to the fact that its utilization is limited to the
subsidiary's separately computed future taxable income and that the subsidiary
has no history of operating profits. The deferred tax asset valuation allowance
increased $1,189,000, $7,308,000 and $11,719,000 in fiscal years 1995, 1994 and
1993, respectively. The $99,000,000 net loss expires at various dates through
2010.

A reconciliation of the income tax provision at the 35% federal statutory rate
to the income tax provision at the effective tax rate is as follows:

Foreign pretax income (loss) was $65,903,000, $23,882,000 and ($15,511,000) in
1995, 1994 and 1993, respectively.

Komag USA (Malaysia) Sdn., the Company's wholly-owned thin-film media operation
in Malaysia, has been granted a tax holiday for a period of five years
commencing in July 1993. Assuming the Company fulfills certain commitments under
its license to operate within Malaysia, this tax holiday may be extended for an
additional five-year period by the Malaysian government. The impact of this tax
holiday was to increase net income by approximately $11,500,000 ($0.23 per
share) and $6,400,000 ($0.14 per share) in 1995 and 1994, respectively. Losses
incurred prior to the commencement of the tax holiday, approximately $6,237,000,
are available for carryforward to years following the expiration of the tax
holiday.

The Company has generated $76,800,000 of earnings for which no U.S. tax has been
provided. These earnings are considered to be permanently invested outside the
United States.


NOTE 8.  TERM DEBT AND LINE OF CREDIT

The Company had no long-term debt outstanding at December 31, 1995. Notes
payable, primarily to banks, totaled approximately $29,482,000 at January 1,
1995. The notes bore interest at various LIBOR and Eurodollar rates plus 1.375%.
The Company used $19,800,000 of the proceeds from its September 1995 public
offering to repay its remaining notes payable.

The Company's credit facilities total $140,000,000 and are comprised of three
four-year term line of credit agreements. These agreements each expire in
December 1999 but may be extended, subject to bank approvals, annually for an
additional year, thus perpetuating their four-year terms. The entire
$140,000,000 under these unsecured credit facilities remains available.



                                       43

The Company's credit facilities require maintenance of certain financial ratios
and compliance with covenants that limit the amount of dividend payments without
the lenders' consents.


NOTE 9.  FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying values of cash and short-term investments, accounts receivable and
certain other liabilities on the Consolidated Balance Sheets approximate fair
value at December 31, 1995 and January 1, 1995 due to the relatively short
period to maturity of the instruments.


NOTE 10.  LEASES AND COMMITMENTS

The Company leases most of its production facilities under operating leases that
expire at various dates between 1996 and 2006. Certain of these leases include
renewal options varying from five to ten years.

At December 31, 1995 the future minimum commitments for all non-cancellable
operating leases are as follows (in thousands):

Rental expense for all operating leases amounted to $4,212,000, $4,319,000 and
$5,471,000 in 1995, 1994 and 1993, respectively.

The Company has current non-cancellable capital commitments of approximately
$165,037,000.


NOTE 11.  DASTEK HOLDING COMPANY

In December 1991 the Company completed a merger with Dastek, Inc. ("Dastek"), a
manufacturer of thin-film magnetic recording heads for use in hard disk drives.
In February 1992 the Company formed a joint venture to produce and market
thin-film magnetic recording heads with Asahi Glass America, Inc. ("Asahi
America"), a U.S. subsidiary of Asahi Glass Co., Ltd. of Japan. Under the joint
venture agreement, the Company contributed to the joint venture both the stock
of Dastek and the assets of its existing thin-film head development program.
Asahi America in turn contributed to the joint venture nearly $60,000,000 in
cash and notes. The notes were paid to the joint venture in 1992 and 1993. Based
on these contributions, the Company and Asahi America obtained interests in the
joint venture of 60% and 40%, respectively. During 1993 the Company and a
subsidiary of Asahi America loaned the Dastek joint venture an additional
$24,000,000 and $16,000,000, respectively.

These loans were revalued to their estimated settlement amounts in late 1993 as
a result of the restructuring of the thin-film head operations. In December 1993
the Company recorded a one-time charge of $38,956,000 as a result of Dastek's
decision to exit the inductive thin-film head business. The net impact of the
restructuring charge, after related minority interest and income tax
adjustments, was $35,389,000 


                                       44
<PAGE>   45
($0.83 loss per share for the year ended January 2, 1994). Approximately
one-half of the restructuring charge related to the reduction of assets and
liabilities to net realizable value. The remaining portion provided for
estimated operating losses to be incurred during the completion of existing
customer orders and the wind down of Dastek's operations. Dastek ceased its
inductive thin-film head operations, sold its equipment at various public
auctions, settled with its creditors and was legally dissolved prior to the end
of 1994. Based upon the results of these actual shutdown activities, no
significant adjustment was required to the aggregate restructuring charge
recorded in 1993. Actual operating losses incurred in 1994 were approximately
one-third higher than estimated in the 1993 restructuring charge. However, net
losses from the sale of Dastek's assets and the settlement of its liabilities
were lower by a comparable amount.


NOTE 12.  KOMAG MATERIAL TECHNOLOGY, INC.

The Company's financial statements include the consolidation of the financial
results of Komag Material Technology, Inc. ("KMT"), which manufactures and sells
aluminum disk substrate products for high-performance magnetic storage media.
KMT was owned 55% by the Company and 45% by Kobe Steel USA Holdings Inc. ("Kobe
USA"), a U.S. subsidiary of Kobe Steel, Ltd. ("Kobe") from November 1988 to
December 1995. On December 28, 1995 the Company increased its ownership of KMT
to 80% through the purchase of KMT Common Stock directly from Kobe USA for
$6,750,000. Kobe USA retained a 20% minority interest investment in KMT.

Other transactions between Kobe or its distributors and the Company were as

NOTE 13.  UNCONSOLIDATED JOINT VENTURE

In 1987 the Company formed a partnership, Komag Technology Partners
("Partnership"), with the U.S. subsidiaries of two Japanese companies and
simultaneously formed a subsidiary, Asahi Komag Co., Ltd. ("AKCL"). The Company
contributed technology in exchange for a 50% interest in the Partnership, and
the subsidiaries of the Japanese companies contributed approximately 1.5 billion
yen (approximately $11 million) in exchange for a 50% interest in the
Partnership. The Partnership then contributed all the cash and licensed the
technology to AKCL in exchange for all of its stock and a limited royalty of 5%
of product produced and sold by AKCL. The Partnership and its subsidiary (joint
venture) established a facility in Japan to manufacture and sell the Company's
thin-film media products in Japan. AKCL also sells its products to the Company
for resale outside of Japan.

The Company's share of the joint venture's net income was $7,362,000, $5,457,000
and $4,860,000 in 1995, 1994 and 1993, respectively. Royalty income ceased in
1992 upon reaching its contractual limit.

NOTE 14.  PARTICIPATION IN HEADWAY TECHNOLOGIES, INC.

The Company has a voting interest in Headway Technologies, Inc. ("Headway").
Headway was formed in 1994 to research, develop and manufacture advanced
magnetoresistive ("MR") heads for the data storage industry. Hewlett-Packard
Company ("HP") and AKCL (see Note 13) provided the initial cash funding to
Headway in exchange for equity interests. The Company and Asahi America licensed
to Headway MR technology developed by Dastek and contributed certain research
and production equipment in exchange for equity. As a result of these
transactions the Company holds a direct voting interest in Headway of less than
20%. The Company has no cost basis in its investment in Headway. Consequently,
operating results at Headway do not directly affect the Company's earnings. The
Company has not guaranteed any obligation of Headway and is not otherwise
committed to provide financial support to Headway.

AKCL invested in Headway in 1994 and has been recording partial writedowns of
its investment based upon net losses incurred at Headway. AKCL's net income
reflected writedowns, net of tax, of $2,200,000 and $500,000 in 1995 and 1994,
respectively. To the extent that such losses continue, AKCL will record a
portion of those losses. Alternatively, AKCL will record a portion of Headway's
net income, if any, to the extent of previously recognized losses.

UNDERTAKING

         For the purposes of complying with the amendments to the rules
governing Form S-8 (effective July 13, 1990) under the Securities Act of 1933,
the undersigned registrant hereby undertakes as follows:



                                       53
<PAGE>   54
         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered on the Form S-8 identified
below, the registrant will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

         The preceding undertaking shall be incorporated by reference into
registrant's Registration Statements on Form S-8 Nos. 33-16625 (filed August 19,
1987), 33-19851 (filed January 28, 1988), 33-25230 (filed October 28, 1988),
33-41945 (filed July 29, 1991), 33-45469 (filed February 3, 1992), 33-53432
(filed October 16, 1992), 33-80594 (filed June 22, 1994), and 33-62543 (filed
September 12, 1995).

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors
Asahi Komag Co., Ltd.

     We have audited the accompanying consolidated balance sheet of Asahi Komag
Co., Ltd. and subsidiary as of December 31, 1995, and the related consolidated
statements of income, cash flows, and stockholder's equity for the year then
ended. We have also audited the accompanying balance sheet of Asahi Komag Co.,
Ltd. as of December 31, 1994, and the related statements of income, cash flows,
and stockholder's equity for each of the years in the two year period ended
December 31, 1994. 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 did not audit the financial
statements of Headway Technologies, Inc., a company investment accounted for
using the equity method, which represents six percent of the Company's total
assets as of December 31, 1995. Those statements were audited by other auditors
whose report has been provided to us and our opinion, insofar as it relates to
the amounts included for Headway Technologies, Inc., is based solely on the
report of the other auditors.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. These 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, based on our audit and the report of other auditors, the
financial statements referred to above present fairly, in all material respects
the consolidated financial position of Asahi Komag Co., Ltd. and subsidiary as
of December 31, 1995, and the consolidated results of its operations and its
cash flows for the year ended December 31, 1995, and the financial position of
Asahi Komag Co., Ltd. as of December 31, 1994 and the results of its operations
and its cash flows for each of the years in the two year period ended December
31, 1994 in conformity with generally accepted accounting principles applicable
in the United States of America.

     As discussed in Note 2b of the notes to the financial statements, the
Company reporting entity changed in 1995 as a result of the establishment of a
wholly owned subsidiary.

     The consolidated financial statements as of and for the year ended December
31, 1995 have been translated into United States Dollars solely for the
convenience of the reader. Our audit included the translation, and in our
opinion such translation has been made in accordance with the basis stated in
note 2g to the financial statements.

Indemnified Parties directly or indirectly, as a result of or arising from any
inaccuracy in or breach or nonfulfillment of any of the representations,
warranties, covenants or agreements made by the Buyer Indemnified Parties in
this Agreement and from any taxes that are the Buyer's responsibility to pay
but which are imposed by any governmental entity or otherwise on the Seller in
connection with the purchase of the Stock (the "Seller Indemnified Parties
Claims" and, together with the Buyer Indemnified Parties Claims, referred to
collectively as the "Claims").

                 6.3      Defense of Claims.  The parties hereto shall promptly
give written notice to



                                       6.

each other after either of them obtains knowledge of any Claim, obligation,
liability or action for which indemnification may be sought hereunder or prompt
written notice of the commencement of any legal proceedings for which
indemnification may be sought hereunder, whichever occurs first; provided, that
the failure to give such notice (other than notice of the commencement of a
legal proceeding) shall not adversely affect any right of indemnification under
this Agreement.  The indemnifying party shall be entitled to control the
defense of any such legal proceeding, through legal counsel reasonably
satisfactory to the indemnified party, at the sole expense of the indemnifying
party, and the indemnified party shall cooperate with the indemnifying party in
the defense of such Claim and shall have the right, but not the obligation, to
participate in the defense at its own expense.  If the indemnifying party
elects not to direct such defense by written notice within fifteen (15) days
after receipt of the original notice, the indemnified party will have the
right, at its own discretion, to direct such defense at the indemnifying
party's sole expense.  The indemnifying party shall have the right to
compromise or settle, with the indemnified party's prior written approval, any
claim or litigation regarding which it is required to indemnify.  If the
indemnified party refuses to approve any compromise or settlement recommended
by the indemnifying party which would have concluded such Claim or litigation
but for the indemnified party's failure to give approval, the indemnifying
party's liability to the indemnified party hereunder with respect to any such
claim or litigation shall not exceed the amount which the indemnifying party
would have paid pursuant to such proposed compromise or settlement.

                 6.4      Successors and Assigns.  Except as otherwise provided
herein, the terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective successors and assigns of the parties
(including transferees of the Stock).  Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement.

                 6.5      Governing Law.  This Agreement shall be governed by
and construed under the laws of the State of California as applied to
agreements among California residents entered into and to be performed entirely
within California.

                 6.6      Counterparts.  This Agreement may be executed in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

                 6.7      Titles and Subtitles.  The titles and subtitles used
in this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

                 6.8      Notices.  Unless otherwise provided, any notice
required or permitted under this Agreement shall be given in writing and shall
be deemed effectively given upon personal delivery to the party to be notified
or upon deposit with the United States Post Office, by registered or certified
mail, postage prepaid and addressed to the party to be notified at the address
indicated for such party on the signature page hereof, or at such other address
as such party may designate by ten (10) days' advance written notice to the
other parties.

                 6.9      Finder's Fee.  Each party represents that it neither
is nor will be obligated for any finders' fee or commission in connection with
this transaction.  The Seller agrees to indemnify and to hold harmless the
Buyer from any liability for any commission or compensation in the nature of a
finders' fee (and the costs and expenses of defending against such liability or
asserted liability) for which the Seller or any of its officers, partners,
employees, or representatives is responsible.  The Buyer agrees to indemnify
and hold harmless the Seller from any liability for



                                       7.
<PAGE>   11
any commission or compensation in the nature of a finders' fee (and the costs
and expenses of defending against such liability or asserted liability) for
which the Buyer or any of its officers, employees or representatives is
responsible.

                 6.10     Expenses.  Irrespective of whether the Closing is
effected, each party shall pay all costs and expenses that it incurs with
respect to the negotiation, execution, delivery and performance of this
Agreement except as set forth in the immediately following sentence.  If any
action at law or in equity is necessary to enforce or interpret the terms of
this Agreement, the prevailing party shall be entitled to reasonable attorney's
fees, costs and necessary disbursements in addition to any other relief to
which such party may be entitled.

                 6.11     Amendments and Waivers.  Any term of this Agreement
may be amended and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Seller and the Buyer.

                 6.12     Severability.  If one or more provisions of this
Agreement are held to be unenforceable under applicable law, such provision
shall be excluded from this Agreement and the balance of the Agreement shall be
interpreted as if such provision were so excluded and shall be enforceable in
accordance with its terms.

                 6.13     Entire Agreement.  This Agreement and the documents
referred to herein constitute the entire agreement among the parties and no
party shall be liable or bound to any other party in any manner by any
warranties, representations, or covenants except as specifically set forth
herein or therein.

                 6.14     Arbitration.  All disputes, controversies or
differences arising out of or in relation to or in connection with this
Agreement, which cannot be settled by discussion and mutual accord, shall be
finally settled by binding arbitration, to be conducted in Palo Alto,
California in accordance with the rules of the American Arbitration
Association.  Demand for arbitration shall be made in writing and shall be
served upon the party or parties to whom the demand is addressed in the manner
provided for the tender of notices in Section 6.8 hereof.  There shall be three
(3) arbitrators and the proceedings shall be conducted in the English language.
Judgment upon the award rendered may be entered in any court having proper
jurisdiction or application made to such court for a judicial acceptance of the
award and an order of enforcement, as the case may be.  The arbitrators shall
be instructed, in connection with the issuance of their award, to prepare a
written finding of facts and law concerning the award.

                 6.15     Non-Exercise of Joint-Venture Option.
Notwithstanding anything to the contrary in the JV Agreement, the execution,
delivery and performance of this Agreement and the other Purchase Documents
shall not be deemed to be an exercise, or to involve or require the exercise,
of any of the Buyer's or the Seller's rights under Section 10.2 of the JV
Agreement and all other rights and obligations of the parties to the JV
Agreement are hereby ratified and confirmed.

                          LICENSE AMENDMENT AGREEMENT


            THIS LICENSE AMENDMENT AGREEMENT (this "Amendment"), dated as of
November 17, 1995, is made among Komag, Incorporated, a Delaware corporation
("Komag"), Komag Material Technology, Inc., a Delaware corporation ("KMT"), and
Kobe Steel, Ltd., a Japanese company ("Kobe").

            WHEREAS, Komag, KMT and Kobe are parties to a Joint Development and
Cross-License Agreement dated as of March 10, 1989 (the "License Agreement");

            WHEREAS, the term of such License Agreement has expired and the
parties hereto wish to reinstate (on the terms and conditions set forth therein
as originally executed except as modified hereby) and extend the term of such
License Agreement; and

            WHEREAS, Komag and Kobe Steel USA Holdings, Inc. are parties to a
Stock Purchase Agreement dated as of the date hereof (the "Stock Purchase
Agreement") and it is a condition precedent to the effectiveness of such Stock
Purchase Agreement that the parties hereto execute and deliver this Amendment.

            NOW, THEREFORE, subject to the terms and conditions hereof, the
parties hereto agree as follows:

            1       Definitions; Reinstatement of License Agreement.  Terms
Defined in License Agreement.  All capitalized terms used in this Amendment and
not otherwise defined herein shall have the meanings assigned to them in the
License Agreement.

            2       Amendments to the License Agreement.

            (a)        Amendments.  The License Agreement shall be restated and
amended as follows, effective as of the date of the occurrence of the Closing,
as defined in the Stock Purchase Agreement.

                  (i)        Article I of the License Agreement is hereby
amended by adding in the following new Sections:

                  "Section 1.4 A  "Inventing Party" shall mean a party to this
            Agreement which employs one or more inventors as that term is used
            before the U.S. Patent and Trademark Office, which inventor or
            inventors contribute or contributes to the invention of a certain
            Joint Invention."

                  "Section 1.4 B  "Joint Inventions" shall mean all
            discoveries, improvements and inventions, conceived or first
            reduced to practice pursuant hereto, as those terms are used before
            the U.S. Patent and Trademark Office which are jointly made by one
            or more Inventing Parties."

                  (ii)       Sections 2.1, 2.2 and 2.3 of the License Agreement
are hereby amended by deleting the phrase "or other products incorporating Disk
Substrates" appearing therein.



                                       1.
<PAGE>   2
                  (iii)            Section 4.5 of the License Agreement is
hereby amended by deleting such Section 4.5 in its entirety and by inserting in
lieu thereof the following new Section 4.5:

                  "4.5 Joint Property.  Joint Inventions shall be jointly owned
            by the Inventing Parties, each Inventing Party having an equal and
            undivided interest therein, subject to the limitations on
            sublicensing set forth in Section 2.4 above as if such Joint
            Inventions were held subject to licenses hereunder.  In such event,
            the Inventing Parties shall all determine whether a patent
            application or applications shall be filed on such Joint
            Inventions, the Inventing Party which will prepare and file such
            application or applications, and the country or countries in which
            the same are to be filed.  The patent expenses incurred shall be
            divided equally among the Inventing Parties.  If the Inventing
            Parties are not able to all agree to file an application or
            applications on a Joint Invention, any one of the Inventing Parties
            may elect to assume such expenses (the "Electing Party").  The
            Electing Party shall control the preparation and prosecution of any
            such applications and all rights in any patents granted thereon
            shall belong exclusively to the Electing Party.  Any Inventing
            Party declining to bear its share of the expenses of prosecuting or
            maintaining patents covering a Joint Invention (the "Declining
            Party") agrees to execute any and all forms, assignments or other
            documents to effect the foregoing; provided, however, that the
            Declining Party shall automatically have a worldwide,
            non-exclusive, royalty-free perpetual license under any patent or
            patents which may be granted with respect to any such Joint
            Invention; provided further, however, that such Declining Party
            shall not have the right to assign, sublicense or otherwise
            transfer the patent or patents, except to an Affiliate.  The
            administration of any licensing of Joint Inventions shall be
            determined when the circumstances arise.  Neither Kobe nor KOMAG
            may, without the prior written consent of the other (which consent
            may be withheld for any reason in its sole and absolute
            discretion), assign or otherwise transfer its interest in any Joint
            Invention except pursuant to Section 8.14 below."

                  (iv)       Section 5.1 of the License Agreement is hereby
amended by deleting such Section 5.1 in its entirety and by inserting in lieu
thereof the following new Section 5.1:

                  "5.1 Term.  This Agreement shall become effective on December
            28, 1995 and shall remain in full force and effect for two (2)
            years unless earlier terminated pursuant to Sections 5.2 or 5.3;
            provided, that such term shall be automatically renewed for
            subsequent two (2) year periods (subject to the effect of Sections
            5.2 and 5.3) unless a written objection of any party hereto is
            received by the other parties hereto prior to the end of the then
            current term, in which case this Agreement will expire at the end
            of such then current term."

                  (v)        Section 7.2 of the License Agreement is hereby
amended by adding the following new clause (c):

                  "(c)  Notwithstanding anything to the contrary in Section
            7.2, any Proprietary Information shall no longer be deemed to be
            "confidential" or "proprietary" for purposes of this Agreement five
            (5) years after the date such Proprietary Information is disclosed
            by any party to any other party hereto."

                  (vi)       Section 7.3(a) of the License Agreement is hereby
amended by adding ", California" after the occurrence of "Palo Alto" therein.

<PAGE>   3
                  (vii)      Section 8.1 of the License Agreement is hereby
amended by (a) deleting "Richard C. Spalding" and by inserting in lieu thereof
"Andrew B. Koslow" and (b) deleting all text relating to Graham & James and by
inserting in lieu thereof the following new text:

                             "Graham & James
                             One Maritime Plaza

                  (viii)     Section 8.14(a) of the License Agreement is hereby
amended by adding the phrase "and except as to those rights specified in
Sections 4.2, 4.3 and 4.4" after the word "below" in the second line thereof.

            (b)   Amendment to Table of Contents.  The Table of Contents of the
License Agreement shall be amended to the extent necessary to reflect the
amendments to the License Agreement made in subsection (a).

            (c)   References Within License Agreement.  Each reference in the
License Agreement to "this Agreement" and the words "hereof," "herein,"
"hereunder," or words of like import, shall mean and be a reference to the
License Agreement as amended by this Amendment.

            3  Miscellaneous.

            (a)   License Agreement Otherwise Not Affected.  Except as
expressly reinstated and amended pursuant hereto, the License Agreement shall
remain unchanged and in full force and effect.  Without limitation, the
provisions of Sections 8.4, 8.5, 8.6, 8.10 and 8.14 of the License Agreement
shall be deemed to be applicable to this Amendment.

            (b)   Complete Agreement; Amendments.  This Amendment, together
with the License Agreement, contains the entire and exclusive agreement of the
parties hereto and thereto with reference to the matters discussed herein and
therein.  This Amendment supersedes all prior commitments, drafts,
communications, discussions and understandings, oral or written, with respect
thereto.  This Amendment may not be modified, amended or otherwise altered
except in accordance with the terms of the License Agreement.

            (c)   Severability.  Whenever possible, each provision of this
Amendment shall be interpreted in such manner as to be effective and valid
under all applicable laws and regulations.  If, however, any provision of this
Amendment shall be prohibited by or invalid under any such law or regulation in
any jurisdiction, it shall, as to such jurisdiction, be deemed modified to
conform to the minimum requirements of such law or regulation, or, if for any
reason it is not deemed so modified, it shall be ineffective and invalid only
to the extent of such prohibition or invalidity without affecting the remaining
provisions of this Amendment, or the validity or effectiveness of such
provision in any other jurisdiction.

            (d)   Counterparts.  This Amendment may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute but one and the same agreement.

            (e)   Interpretation.  This Amendment is the result of negotiations
among the parties hereto, and is the product of all parties hereto.
Accordingly, this Amendment shall not be construed against a particular party
merely because of such party's involvement in the preparation thereof.

required by the Financial Accounting Standards Board of the American Institute
of Certified Public Accountants (or successors thereto or agencies with similar

                              THE REVOLVING LOANS

    II.1.  THE REVOLVING LOANS.

         (a)  The Commitment.  Bank agrees, on the terms and conditions 
hereinafter set forth, to make loans ("Revolving Loans") to Borrower from time
to time during the period from the date hereof to and including the Maturity
Date in the aggregate principal amount not to exceed at any one time outstanding
the Commitment, as such amount may be reduced pursuant to Section 2.1(e). Each
Revolving Loan shall be in a minimum amount of $1,000,000 and in an integral
multiple of $100,000 above such amount for a Prime Rate Loan and in a minimum
amount of $1,000,000 and in an integral multiple of $500,000 above such amount
for a Eurodollar Rate Loan. Within the limits of each Commitment, Borrower may
borrow, repay pursuant to Section 2.2(b) and reborrow under this Section,
provided that at no time shall the aggregate principal amount of outstanding
Revolving Loans exceed the Commitment then in effect.

         (b)  Making the Revolving Loans.  Borrower may borrow under the 
Commitment on any Business Day if the Revolving Loan is to be a Prime Rate Loan
and on any Eurodollar Business Day if the Revolving Loan is to be a Eurodollar
Rate Loan, provided Borrower shall give Bank irrevocable notice in the form of
Exhibit A (which notice 


                                      -10-
<PAGE>   14
must be received by Bank prior to 9:00 A.M., San Francisco time) (i) three
Eurodollar Business Days prior to the requested borrowing date in the case of a
Eurodollar Rate Loan, and (ii) on the Business Day of the requested borrowing in
the case of a Prime Rate Loan, specifying (A) the amount of the proposed
Revolving Loan, (B) the requested date of the Revolving Loan, (C) whether the
Revolving Loan is to consist of a Prime Rate Loan or a Eurodollar Rate Loan, and
(D) if the Revolving Loan is to be a Eurodollar Rate Loan, the length of the
Interest Period therefor. Upon satisfaction of the applicable conditions set
forth in this Section and in Article IV, the proceeds of such Revolving Loan
will then be made available to Borrower by Bank by crediting the account of
Borrower on the books of Bank, or as otherwise directed by Borrower.

         The notice of Revolving Loan may be given orally (including 
telephonically) or in writing (including telex or facsimile transmission) and
any conflict regarding a notice or between an oral notice and a written notice
applicable to the same Revolving Loan shall be conclusively determined by Bank's
books and records. Bank shall not incur any liability to Borrower in acting upon
any notice of Revolving Loan which Bank believes in good faith to have been
given by a Person duly authorized to give such notice on behalf of Borrower.

         (c)  Arrangement Fee.  Borrower agrees to pay to Bank, on the date of 
Borrower's execution of this Agreement, the arrangement fee specified in the
letter from Bank to Borrower, dated October 26, 1995.

         (d)  Commitment Fee.  Borrower agrees to pay to Bank a commitment fee 
equal to 0.10% per annum of the maximum amount of the Commitment (whether or not
used), which shall be calculated on the basis of a 365-day year for the actual
days elapsed, payable quarterly in arrears on the last day of each December,
March, June, and September, commencing the first such date occurring after the
date of this Agreement, and on the Maturity Date.

         (e)  Reduction of the Commitment.  Borrower shall have the right, upon 
at least two (2) Business Days' notice to Bank, to terminate in whole or reduce
in part the unused portion of the Commitment, without premium or penalty,
provided that each partial reduction shall be in the aggregate amount of
$1,000,000 or an integral multiple of $1,000,000 thereof and that such reduction
shall not reduce the Commitment to an amount less than the amount 


                                      -11-
<PAGE>   15
outstanding hereunder on the effective date of the reduction. Such notice shall
be irrevocable and such reduction shall not be reinstated.

         (f)  Revolving Note.  The Revolving Loans made by Bank pursuant hereto 
shall be evidenced by a promissory note of Borrower, substantially in the form
of Exhibit B, with appropriate insertions (the "Revolving Note"), payable to the
order of Bank and representing the obligation of Borrower to pay the aggregate
unpaid principal amount of the Revolving Loans made by Bank to Borrower, with
interest thereon as prescribed in Section 2.3. Bank is hereby authorized to
record in its books and records and on any exhibit annexed to Revolving Note,
the date and amount of each Revolving Loan made by Bank and the date and amount
of each payment of principal thereof, and in the case of Eurodollar Rate Loans,
the Interest Period and interest rate with respect thereto, and any such
recordation shall constitute prima facie evidence of the accuracy of the
information so recorded; provided that failure by Bank to effect such
recordation shall not affect Borrower's obligations hereunder. Prior to the
transfer of the Revolving Note, Bank shall record such information on any
exhibit annexed to and forming a part of the Revolving Note.

         (g)  Non-Utilization Fee.  Borrower agrees to pay to Bank a 
non-utilization fee on the average daily unused portion of the Commitment from
the date of this Agreement until the Maturity Date, or any extensions thereof,
at the rate of 0.10% per annum, which shall be calculated on the basis of a
365-day year for the actual days elapsed, payable on the last day of each
December, March, June, and September (for the preceding quarter) commencing the
first such date occurring after the date of this Agreement and on the Maturity
Date.

         (h)  Extension of Maturity Date.  Notwithstanding anything to the 
contrary contained in this Agreement, the Maturity Date may be extended for
additional one year periods on each anniversary date of this Agreement. A
request for an extension of the Maturity Date may be made by Borrower not more
than 60 nor less than 30 days prior to each anniversary of the date of this
Agreement. Within 15 days of its receipt of a request by Borrower to extend the
Maturity Date, Bank shall notify Borrower whether it agrees to the requested
extension of the Maturity Date (which decision shall be in the absolute
discretion of Bank). The failure by Bank to respond to any extension request
within the applicable period, shall be deemed a 



                                      -12-
<PAGE>   16
rejection of such request. Each extension of the Maturity Date agreed to by Bank
shall be evidenced by an amendment to this Agreement. In connection with the
making of any request for an extension of the Maturity Date, Borrower shall
provide to Bank any documents, instruments, records, information, or access to
management personnel that Bank may reasonably request.

    II.2.     REPAYMENT.

         (a)  Mandatory Repayments. The aggregate principal amount of the 
Revolving Loans outstanding on the Maturity Date, together with accrued interest
thereon, shall be due and payable in full on the Maturity Date. If at any time
the aggregate principal amount of outstanding Revolving Loans exceeds the
Commitment then in effect, Borrower shall immediately repay the Revolving Loans
in an amount equal to the excess.

         (b)  Optional Payment.  Borrower may at its option repay the Revolving 
Loans, without penalty except as set forth in Section 3.7(b), in whole or in
part, on any Business Day, prior to the Maturity Date, from time to time,
provided Bank shall have received from Borrower notice of any such payment at
least: (i) three Business Days prior to the date of the proposed payment if the
Revolving Loan being prepaid is a Eurodollar Rate Loan, and (ii) one Business
Day prior to the date of the proposed payment if the Revolving Loan being
prepaid is a Prime Rate Loan. For Prime Rate Loans, each day shall be defined as
and constitute an "Interest Period." Partial payments hereunder shall be in an
aggregate principal amount of not less than the lesser of (a) $1,000,000 and in
an integral multiple of $100,000 for a Revolving Loan consisting of a Prime Rate
Loan; (b) $1,000,000 and in an integral multiple of $500,000 for a Revolving
Loan consisting of a Eurodollar Rate Loan; and (c) the outstanding balance of
the Revolving Loan being paid.

         (c)  Allocation of Payments Following an Event of Default.  Following 
the occurrence of an Event of Default and acceleration of the Revolving Loans,
all amounts received by Bank on account of the Revolving Loans shall be applied
by Bank as follows:

              (i)   First, to the payment of expenses incurred by Bank in the 
enforcement of its rights under the Loan Documents, including, without
limitation, all costs and expenses of collection, attorneys' fees and 


                                      -13-
<PAGE>   17
court costs; and

              (ii)  then, to the outstanding principal balance of all Revolving 
Loans and interest accrued thereon.

    II.3.     INTEREST RATE AND PAYMENT DATES.

         (a)  Payment of Interest.  Interest with respect to each Revolving Loan
shall be payable in arrears on each Interest Payment Date for such Revolving
Loan. In no event shall interest on a Revolving Loan exceed the maximum rate
permitted by applicable law.

         (b)  Prime Rate Loans.  Revolving Loans which are Prime Rate Loans 
shall bear interest on the unpaid principal amount thereof at a rate per annum
equal to the Prime Rate from the date hereof through the Maturity Date. Bank
shall promptly notify Borrower of the amount and the effective date of each
adjustment in the Prime Rate, provided that no failure or delay in giving any
such notice shall affect or delay the making of any such adjustments or the
obligation of Borrower to pay in a timely manner the interest due on such
Revolving Loans.

         (c)  Eurodollar Rate Loans.  Revolving Loans which are Eurodollar Rate 
Loans shall bear interest for each Interest Period with respect thereto on the
unpaid principal amount thereof at a rate per annum equal to the Eurodollar Rate
determined for such Interest Period plus 0.625 percentage points.

    II.4.     CONTINUATION AND CONVERSION OPTIONS. Borrower may elect from time 
to time to convert outstanding Revolving Loans from Revolving Loans bearing
interest at a rate determined by reference to one basis to Revolving Loans
bearing interest at a rate determined by reference to an alternative basis if
Borrower gives Bank (i) at any time irrevocable notice of an election to convert
Eurodollar Rate Loans to Prime Rate Loans and (ii) at least three Eurodollar
Business Days' prior irrevocable notice of an election to convert Prime Rate
Loans to Eurodollar Rate Loans, provided that any conversion of Eurodollar Rate
Loans to Prime Rate Loans shall only be made on the last day of an Interest
Period with respect thereto, and provided further that no Prime Rate Loan may be
converted to a Eurodollar Rate Loan so long as an Event of Default or Potential
Event of Default has occurred and is continuing. Borrower may elect from time to
time to 


                                      -14-
<PAGE>   18
continue its outstanding Eurodollar Rate Loans upon the expiration of the
Interest Period(s) applicable thereto if Borrower gives to Bank irrevocable
notice of continuation of such a Eurodollar Rate at least one Eurodollar
Business Days' prior to the expiration thereof and so long as an Event of
Default or Potential Event of Default has not occurred and is not continuing.
Each notice electing to convert or continue a Revolving Loan shall specify: (i)
the proposed conversion/continuation date; (ii) the amount of the Revolving Loan
to be converted/continued; (iii) the nature of the proposed
continuation/conversion; and (iv) in the case of a conversion to, or
continuation of a Eurodollar Rate Loan, the requested Interest Period, and shall
certify that no Event of Default or Potential Event of Default has occurred and
is continuing. On the date on which such conversion or continuation is being
made Bank shall take such action as is necessary to effect such conversion or
continuation. In the event that no notice of continuation or conversion is
received by Bank with respect to outstanding Eurodollar Rate Loans, upon
expiration of the Interest Period(s) applicable thereto, such Eurodollar Rate
Loans shall convert to Prime Rate Loans. Subject to the limitations set forth in
this Section and in the definition of Interest Period, all or any part of
outstanding Revolving Loans may be converted or continued as provided herein,
provided that partial conversions or continuations shall be in an aggregate
principal amount of not less than (a) $1,000,000 and in an integral multiple of
$100,000 for a Revolving Loan consisting of a Prime Rate Loan; (b) $1,000,000
and in an integral multiple of $500,000 above such amount for a Eurodollar Rate
Loan; and (c) the outstanding balance of the Revolving Loan being converted or
continued.

                                       III

               GENERAL PROVISIONS CONCERNING THE REVOLVING LOANS

    III.1.    USE OF PROCEEDS.  The proceeds of the Revolving Loans hereunder 
shall be used by Borrower for general corporate purposes.

    III.2.    POST MATURITY INTEREST. Notwithstanding anything to the contrary
contained in Section 2.3, if all or a portion of the principal amount of any of
the Revolving Loans made hereunder or any interest accrued thereon shall not be
paid when due (whether at the stated maturity, by acceleration or otherwise),
any such overdue 


                                      -15-
<PAGE>   19
amount shall bear interest at a rate per annum which is equal to the greater of
(a) two percent (2%) above the rate which would otherwise be applicable pursuant
to Section 2.3 and (b) two percent (2%) above the Prime Rate, from the date of
such nonpayment until paid in full (after as well as before judgment), payable
on demand. In addition, such Revolving Loan, if a Eurodollar Rate Loan, shall be
converted to a Prime Rate Loan at the end of the then current Interest Period
therefor.

    III.3.    COMPUTATION OF INTEREST

         (a)  Calculations.  Interest in respect of the Prime Rate Loans shall 
be calculated on the basis of a 365-day year for the actual days elapsed. Any
change in the interest rate on a Prime Rate Loan resulting from a change in the
Prime Rate shall become effective as of the opening of business on the date on
which such change in the Prime Rate shall become effective. Interest with
respect of the Eurodollar Rate Loans shall be calculated on the basis of a
360-day year for the actual days elapsed.

         (b)  Determination by Bank.  Each determination of an interest rate or 
fee by Bank pursuant to any provisions of this Agreement shall be conclusive and
binding on Borrower in the absence of manifest error.

    III.4.    PAYMENTS. Borrower shall make each payment of principal, interest,
and fees referred to in Section 2.2 due from it hereunder and under the
Revolving Note, without setoff or counterclaim, not later than 12:00 P.M. (San
Francisco time) on the day when due in lawful money of the United States of
America to Bank, at the office of Bank designated from time to time in
immediately available funds.

    III.5.    PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to be made
hereunder or under the Revolving Note shall be stated to be due on a day which
is not a Business Day, such payment may be made on the next succeeding Business
Day and with respect to payments of principal, interest thereon shall be payable
at the then applicable rate during such extension.

    III.6.    REDUCED RETURN. If Bank shall have determined that any new or
additional applicable law, regulation, rule, or regulatory requirement
(collectively in this Section 3.6 "Requirement") regarding capital 


                                      -16-
<PAGE>   20
adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank, or
comparable agency charged with the interpretation of administration thereof, or
compliance by Bank with any new or additional request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank, or comparable agency, has or would have the effect of reducing the
rate of return on Bank's capital as a consequence of the Commitment and
obligations hereunder to a level below that which would have been achieved but
for such Requirement, change, or compliance (taking into consideration Bank's
policies with respect to capital adequacy) by an amount deemed by Bank to be
material (which amount shall be determined by Bank's reasonable allocation of
the aggregate of such reductions resulting from such events), then from time to
time, within thirty (30) Business Days after written demand by Bank, Borrower
shall pay to Bank such additional amount or amounts as will compensate Bank for
such reduction. Notwithstanding the foregoing, no additional compensation will
be required from Borrower under this Section 3.6 if the reason for additional
compensation was based solely on Bank's failure to comply with any existing or
new law, treaty, rule, or regulation or requirement. In addition, Bank shall
promptly notify Borrower of any proposed request for compensation under this
Section 3.6 and shall provide Borrower with reasonable support therefor. Any
request by Bank for additional compensation shall be structured to allocate such
additional costs over the term of the credit affected thereby.

    III.7.    INDEMNITIES.

         (a)  General.  Whether or not the transactions contemplated hereby 
shall be consummated, Borrower agrees to indemnify, pay and hold Bank, and the
shareholders, officers, directors, employees, and agents of Bank, harmless from
and against any and all claims, liabilities, losses, damages, costs, and
expenses (whether or not any of the foregoing Persons is a party to any
litigation), including, without limitation, reasonable attorneys' fees and costs
(including, without limitation, the reasonable estimate of the allocated cost of
in-house legal counsel and staff) and costs of investigation, document
production, attendance at a deposition, or other discovery, with respect to or
arising out of any proposed acquisition by Borrower or any of its Consolidated
Subsidiaries of any Person or any securities (including a self-tender), this
Agreement or any use of proceeds 


                                      -17-
<PAGE>   21
hereunder, or any claim, demand, action or cause of action being asserted
against Borrower or any of its Consolidated Subsidiaries (collectively, the
"Indemnified Liabilities"), provided that Borrower shall have no obligation
hereunder with respect to Indemnified Liabilities arising from the gross
negligence or willful misconduct of any such Persons. If any claim is made, or
any action, suit or proceeding is brought, against any Person indemnified
pursuant to this Section, the indemnified Person shall notify Borrower of such
claim or of the commencement of such action, suit or proceeding, and Borrower
will assume the defense of such action, suit or proceeding, employing counsel
selected by Borrower and reasonably satisfactory to the indemnified Person, and
pay the fees and expenses of such counsel. This covenant shall survive
termination of this Agreement and payment of the outstanding Revolving Note.

         (b)  Funding Losses.  Borrower agrees to indemnify Bank and to hold 
Bank harmless from any loss or expense including, but not limited to, any such
loss or expense arising from interest or fees payable by Bank to lenders of
funds obtained by Bank in order to maintain its Eurodollar Rate Loans hereunder,
which Bank may sustain or incur as a consequence of (i) default by Borrower in
payment of the principal amount of or interest on the Eurodollar Rate Loans of
Bank, (ii) default by Borrower in making a conversion or continuation after
Borrower has given a notice thereof, (iii) default by Borrower in making any
payment after Borrower has given a notice of payment or (iv) Borrower making any
payment of a Eurodollar Rate Loan on a day other than the last day of the
Interest Period for such Revolving Loan. For purposes of this Section and
Section 3.10, it shall be assumed that Bank had funded or would have funded one
hundred percent (100%) of each Eurodollar Rate Loan in the interbank Eurodollar
market for a corresponding amount and term. In the event of a payment set forth
in (iv) above, Borrower shall be credited with a reinvestment interest rate
equal to one sixteenth of one percent (.0625%) less than the rate of interest
generally available to Bank at the time of the payment for a period of time
approximately equal to the period remaining on the then applicable Interest
Period and for an amount approximately equal to the amount of the payment. The
determination of such amount by Bank shall be presumed correct in the absence of
manifest error. This covenant shall survive termination of this Agreement and
payment of the outstanding Revolving Note.

    III.8.    FUNDING SOURCES. Nothing in this Agreement 


                                      -18-
<PAGE>   22
shall be deemed to obligate Bank to obtain the funds for any Revolving Loan in
any particular place or manner or to constitute a representation by Bank that it
has obtained or will obtain the funds for any Revolving Loan in any particular
place or manner.

    III.9.    INABILITY TO DETERMINE INTEREST RATE. In the event that Bank shall
have determined (which determination shall be conclusive and binding upon
Borrower) that by reason of circumstances affecting the interbank Eurodollar
market, adequate and reasonable means do not exist for ascertaining the
Eurodollar Rate applicable pursuant to Section 2.3 for any Interest Period with
respect to a Eurodollar Rate Loan that will result from a requested Eurodollar
Rate Loan or that such rate of interest does not adequately cover the cost of
funding such Revolving Loan, Bank shall forthwith give notice of such
determination to Borrower not later than 1:00 P.M., San Francisco time, on the
requested Borrowing date, the requested conversion date or the last day of an
Interest Period of a Revolving Loan which was to have been continued as a
Eurodollar Rate Loan. If such notice is given and has not been withdrawn (i) any
requested Eurodollar Rate Loan shall be made as a Prime Rate Loan, or, at
Borrower's option, such Revolving Loan shall not be made, (ii) any Revolving
Loan that was to have been converted to a Eurodollar Rate Loan, shall be
continued as, or converted into, a Prime Rate Loan and (iii) any outstanding
Eurodollar Rate Loan shall be converted, on the last day of the then current
Interest Period with respect thereto, to a Prime Rate Loan. Until such notice
has been withdrawn by Bank, no further Eurodollar Rate Loans shall be made and
Borrower shall not have the right to convert a Revolving Loan to a Eurodollar
Rate Loan. Bank will review the circumstances affecting the interbank Eurodollar
market from time to time and Bank will withdraw such notice at such time as it
shall determine that the circumstances giving rise to said notice no longer
exist.

    III.10.   REQUIREMENTS OF LAW. In the event that any law, regulation, or
directive or any change therein or in the interpretation or application thereof
or compliance by Bank with any request or directive (whether or not having the
force of law) from any central bank or other governmental authority, agency or
instrumentality:

         (a)  does or shall subject Bank to any new or additional tax of any 
kind whatsoever with respect to this Agreement, the Revolving Note, or any
Revolving Loan made hereunder, or change the basis of taxation of payments to


                                      -19-
<PAGE>   23
Bank of principal, commitment fee, non-utilization fee, interest, or any other
amount payable hereunder (except for changes in the rate of tax on the overall
net income of Bank);

         (b)  does or shall impose, modify, or hold applicable any reserve, 

assessment rate, special deposit, compulsory loan, or other requirement
(collectively in this Section 3.10 "Requirements") against assets held by, or
deposits or other liabilities in or for the account of, advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
Bank which Requirements are not otherwise included in the determination of any
Eurodollar Rate at the last Borrowing conversion or continuation date of a
Revolving Loan;

         (c)  does or shall impose, modify or hold applicable any of the 
Requirements against the Commitment; or

         (d)  does or shall impose on Bank any other new or additional 
condition; 

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining the Commitment or the Eurodollar Rate Loans or
to reduce any amount receivable thereunder by an amount determined by Bank, in
its sole discretion, to be material (which increase or reduction shall be
determined by Bank's reasonable allocation of the aggregate of such cost
increases or reduced amounts receivable resulting from such events), then, in
any such case, Borrower shall pay to Bank, within thirty (30) Business Days of
its demand, any additional amounts necessary to compensate Bank for such
additional cost or reduced amount receivable as determined by Bank with respect
to this Agreement. If Bank becomes entitled to claim any additional amounts
pursuant to this subsection, it shall notify Borrower of the event by reason of
which it has become so entitled. A statement incorporating the calculation as to
any additional amounts payable pursuant to the foregoing sentence submitted by
Bank to Borrower shall be conclusive in the absence of manifest error.
Notwithstanding the foregoing, no additional compensation will be required from
Borrower under this Section 3.10 if the reason for said additional compensation
was based solely on Bank's failure to comply with any existing or new law,
treaty, rule, regulation, or requirement. In addition, Bank shall promptly
notify Borrower of any proposed request for compensation under this Section 3.10
and shall provide 


                                      -20-
<PAGE>   24
Borrower with reasonable support therefor. Any request by Bank for additional
compensation shall be structured to allocate such additional costs over the term
of the credit affected thereby.

    III.11.   ILLEGALITY. Notwithstanding any other provisions herein, if any 
law, regulation, treaty, or directive or any change therein or in the
interpretation or application thereof, shall make it unlawful, impossible or
impracticable for Bank to make or maintain Eurodollar Rate Loans as contemplated
by this Agreement, (a) the commitment of Bank hereunder to make Eurodollar Rate
Loans or convert Prime Rate Loans to Eurodollar Rate Loans shall forthwith be
suspended and (b) Bank's Revolving Loans then outstanding as Eurodollar Rate
Loans, if any, shall be converted automatically to Prime Rate Loans on the next
succeeding Interest Payment Date or within such earlier period as allowed by
law. Borrower hereby agrees to pay Bank, within thirty (30) Business Days of its
demand, any additional amounts necessary to compensate Bank for any costs
incurred by Bank in making any conversion in accordance with this Section,
including, but not limited to, any interest or fees payable by Bank to lenders
of funds obtained by it in order to make or maintain its Eurodollar Rate Loans
hereunder (Bank's notice of such costs, as certified to Borrower to be
conclusive absent manifest error). Notwithstanding the foregoing, no additional
compensation will be required from Borrower under this Section 3.11 if the
reason for said additional compensation was based solely on Bank's failure to
comply with any existing or new law, treaty, rule or regulation or requirement.
In addition Bank shall promptly notify Borrower of any proposed request for
compensation under this Section 3.11 and shall provide Borrower with reasonable
support therefor. Any request by Bank for additional compensation shall be
structured to allocate such additional costs over the term of the credit
affected thereby.

                         REPRESENTATIONS AND WARRANTIES

    V.1. REPRESENTATIONS AND WARRANTIES.  In order to induce Bank to make the 
Revolving Loans, Borrower represents and warrants as follows:

         (a)  Organization.  Borrower is duly organized, validly existing, and 
in good standing under the laws of the state of its formation. Borrower is also
duly authorized, qualified, and licensed in all applicable jurisdictions, and
under all applicable laws, regulations, ordinances, or orders of public
authorities, to carry on its business in the locations and in the manner
presently conducted, to the extent that the failure to do so could not
reasonably be expected to have a Material Adverse Effect. All of the
Subsidiaries and Consolidated Subsidiaries of Borrower and the percentage of
Borrower's 


                                      -23-
<PAGE>   27
ownership interest therein as of the date of this Agreement are identified on
Schedule 2.

         (b)  Authorization.  The execution, delivery, and performance by 
Borrower of the Loan Documents, and the making of Borrowings hereunder, are
within Borrower's corporate powers, have been duly authorized by all necessary
corporate action and do not contravene (i) Borrower's certificate of
incorporation, by-laws or other organizational documents or (ii) any law or
regulation (including Regulations G, T, U, and X) or any contractual restriction
binding on or affecting Borrower.

         (c)  Governmental Consents.  No authorization or approval or other 
action by, and no notice to or filing with, any governmental authority or
regulatory body (except routine reports required pursuant to the Securities
Exchange Act of 1934, as amended (if such act is applicable to Borrower), which
reports will be made in the ordinary course of business) is required for the due
execution, delivery, and performance by Borrower of the Loan Documents.

         (d)  Validity.  The Loan Documents are the binding obligations of 
Borrower, enforceable in accordance with their respective terms; except in each
case as such enforceability may be limited by bankruptcy, insolvency,
reorganization, liquidation, moratorium, or other similar laws of general
application and equitable principles relating to or affecting creditors' rights.

         (e)  Financial Condition.  The balance sheets of Borrower and its 
Consolidated Subsidiaries as at the fiscal quarter ended July 2, 1995 and the
fiscal year ended January 1, 1995, and the related statements of income and
retained earnings of Borrower and its Consolidated Subsidiaries to that date and
the fiscal year then ended, copies of which have been furnished to Bank, fairly
present the financial condition of Borrower and its Consolidated Subsidiaries as
at such dates and the results of the operations of Borrower and its Consolidated
Subsidiaries for the respective periods ended on such dates, all in accordance
with GAAP, consistently applied. Since January 1, 1995, there has been no
material adverse change in the business, operations, properties, assets, or
condition (financial or otherwise) of Borrower and its Consolidated
Subsidiaries, taken as a whole.

         (f)  Litigation.  Except as set forth in the 


                                      -24-
<PAGE>   28
financial statements delivered on or prior to the date hereof, to the best of
Borrower's knowledge there is no pending or threatened action or proceeding
affecting Borrower or any of its Consolidated Subsidiaries before any court,
governmental agency, or arbitrator, which may materially adversely affect the
consolidated financial condition or operations of Borrower or which may have a
material adverse effect on Borrower's ability to perform its obligations under
the Loan Documents, having regard for its other financial obligations (a
"Material Adverse Effect").

         (g)  Employee Benefit Plans.  Borrower and each of its ERISA Affiliates
is in compliance in all material respects with any applicable provisions of
ERISA and the regulations and published interpretations thereunder wish respect
to all Employee Benefit Plans. No Termination Event has occurred or is
reasonably expected to occur with respect to any Pension Plan that would
reasonably be expected to have a Material Adverse Effect.

         (h)  Disclosure.  No representation or warranty of Borrower contained 
in this Agreement or any other document, certificate, or written statement
furnished to Bank or on behalf of Borrower for use in connection with the
transactions contemplated by this Agreement contains any untrue statement of a
material fact or omits to state a material fact (known to Borrower in the case
of any document not furnished by it) necessary in order to make the statements
contained herein or therein not misleading. To the best of Borrower's knowledge,
there is no fact known to Borrower (other than matters of a general economic
nature) which materially adversely affects the business, operations, property,
assets, or condition (financial or otherwise) of Borrower and its Consolidated
Subsidiaries, taken as a whole, which has not been disclosed herein or in such
other documents, certificates and statements furnished to Bank for use in
connection with the transactions contemplated hereby.

         (i)  Margin Stock.  The aggregate value of all margin stock (as defined
in Regulation U) directly or indirectly owned by Borrower and its Consolidated
Subsidiaries is less than 25% of the aggregate value of Borrower's assets.

         (j)  Environmental Matters.  Except as set forth in the financial 
statements delivered on or prior to the date hereof and except for certain
claims associated with Great Western Chemical, neither Borrower nor any


                                      -25-
<PAGE>   29
Consolidated Subsidiary, nor, to the best of their knowledge, any other person,
has treated, stored, processed, discharged, spilled, or otherwise disposed of
any substance defined as hazardous or toxic by any applicable federal, state, or
local law, rule, regulation, order, or directive, or any waste or by-product
thereof, at any real property or any other facility owned, leased, or used by
Borrower or any Consolidated Subsidiary, in violation of any applicable
statutes, regulations, ordinances, or directives of any governmental authority
or court, which violations may result in liability to Borrower or any
Consolidated Subsidiary in an amount for all such violations that could
reasonably be expected to have a Material Adverse Effect; and the unresolved
violations, if any, set forth in the financial statements delivered on or prior
to the date hereof will not result in liability to Borrower or any Consolidated
Subsidiary in an amount for all such unresolved violations that could reasonably
be expected to have a Material Adverse Effect. Except as set forth in the
financial statements delivered on or prior to the date hereof, no employee or
other person has ever made a claim or demand against Borrower or any
Consolidated Subsidiary based on alleged damage to health caused by any such
hazardous or toxic substance or by any waste or by-product thereof in an amount
that could reasonably be expected to have a Material Adverse Effect; and the
unsatisfied claims, if any, or demands against Borrower or any Consolidated
Subsidiary set forth in the financial statements delivered on or prior to the
date hereof will not result in uninsured liability to Borrower or any
Consolidated Subsidiary or any of their respective officers, employees,
representatives, agents, or shareholders in an amount that could reasonably be
expected to have a Material Adverse Effect for all such unsatisfied claims or
demands. Except as set forth in the financial statements delivered on or prior
to the date hereof neither Borrower nor any Consolidated Subsidiary has been
charged by any governmental authority with improperly using, handling, storing,
discharging, or disposing of any such hazardous or toxic substance or waste or
by-product thereof or with causing or permitting any pollution of any body of
water in an amount that could reasonably be expected to have a Material Adverse
Effect; and the outstanding charges, if any, set forth in the financial
statements delivered on or prior to the date hereof will not result in liability
to Borrower or any Consolidated Subsidiary or any or their respective officers,
employees, representatives, agents, or shareholders in an amount that could
reasonably be expected to have a Material Adverse Effect for all such


                                      -26-
<PAGE>   30
outstanding charges.

         (k)  Employee Matters.  There is no strike or work stoppage in 
existence or, to the best of Borrower's knowledge, threatened involving Borrower
or its Consolidated Subsidiaries that could reasonably be expected to have a
Material Adverse Effect.

                                       VI

Consolidated Subsidiaries to exercise, all due diligence in order to comply with
the requirements of all applicable laws, rules, regulations, and orders of any

include Borrower's future net income after July 3, 1994), plus (ii) 100% of the
net proceeds of equity investments and issues received by Borrower or its

                                      VIII

                                  MISCELLANEOUS

    VIII.1.   AMENDMENTS, ETC. No amendment or waiver of any provision of the 
Loan Documents nor consent to any departure by Borrower therefrom, shall in any
event be effective unless the same shall be in writing and signed by Bank, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.

    VIII.2.   NOTICES, ETC. Except as otherwise set forth in this Agreement, all
notices and other communications provided for hereunder shall be in writing
(including telegraphic, telex, or facsimile communication) and mailed or
telegraphed or telexed or sent by facsimile or delivered, if to Borrower, at
Borrower's address set forth on the signature page hereof; and if to Bank, at
its address set forth on the signature page hereof; or, as to each party at such
other address as shall be designated by such party in a written notice to the
other parties. All such notices and communications shall be effective when
deposited in the mails, delivered to the telegraph company, sent by telex or
sent by facsimile respectively, except that notices and communications to Bank
pursuant to Article II shall not be effective until received by Bank.

    VIII.3.   RIGHT OF SETOFF. Upon and during the continuance of any Event of
Default, Bank and any participant with Bank in the Commitment pursuant to
Section 8.6 is hereby authorized by Borrower, at any time, and from time to
time, without prior notice, (a) to set off against, and to appropriate and apply
to the payment of, the obligations and liabilities of Borrower under the 


                                      -39-
<PAGE>   43
Loan Documents (whether matured or unmatured, fixed or contingent or liquidated
or unliquidated) any and all amounts owing by Bank or such participant to
Borrower (whether payable in Dollars or any other currency, whether matured or
unmatured, and, in the case of deposits, whether general or special, time or
demand and however evidenced), and (b) pending any such action, to the extent
necessary, to hold such amounts as collateral to secure such obligations and
liabilities and to return as unpaid for insufficient funds any and all checks
and other items drawn against any deposits so held as Bank or such participant
in its sole discretion may elect. Bank agrees promptly to notify Borrower (and
to cause each such participant to notify Borrower) after any such set-off and
application is made. Upon and during the continuance of any Event of Default,
Bank and all such participants are authorized to debit any account maintained
with it by Borrower for any amount of principal, interest, or fees which are
then due and owing to Bank or such participants by Borrower.

    VIII.4.   NO WAIVER: REMEDIES. No failure on the part of Bank to exercise, 
and no delay in exercising, any right under any of the Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right under any of the Loan Documents preclude any other or further exercise
thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

    VIII.5.   COSTS AND EXPENSES. Borrower agrees to pay, within 30 days of 
demand therefor by Bank (but on demand if there shall then exist any Event of
Default), all costs and expenses (i) of Bank (including reasonable and
documented attorneys' fees and reasonable and documented costs of in-house
counsel and staff) in connection with the preparation, amendment, or
modification of the Loan Documents, and (ii) of Bank in connection with the
enforcement (including, without limitation, in appellate, bankruptcy,
insolvency, liquidation, reorganization, moratorium, or other similar
proceedings) or restructuring of the Loan Documents; provided that Borrower's
obligation to reimburse Bank for such attorneys' fees in connection with the
preparation of the Loan Documents shall be limited to $5,000; provided further
that the foregoing limitation shall not apply to any such costs and expenses
attributable (in the reasonable judgment of Bank) to (i) any material change
(other than at the request of Bank) in the terms and conditions set forth in the
Summary of Terms and Conditions (attached to a letter from Bank to 


                                      -40-
<PAGE>   44
Andrew Koslow, Esq., dated October 16, 1995), dated October 16, 1995, or (ii)
any failure by Borrower, or any representative acting on behalf of Borrower
reasonably to cooperate with the efficient closing of the transaction
contemplated by the Loan Documents.

    VIII.6.   PARTICIPATIONS. (a) Bank may sell, negotiate, or grant 
participations in all or part of the obligations of Borrower outstanding under
the Loan Documents, subject to the prior written approval of Borrower (which
approval shall not be unreasonably withheld); provided that any such sale,
negotiation or participation shall be in compliance with the applicable federal
and state securities laws. Notwithstanding the foregoing, Bank shall not sell,
negotiate, or grant participations unless it retains at least $20,000,000 of the
Commitment or another amount as agreed upon by Borrower and Bank. Bank shall not
transfer or grant any participating interest under which the participant shall
have rights: (i) greater than Bank under Sections 3.6, 3.7, or 3.10 of this
Agreement, or (ii) to approve any amendment to, or any consent or waiver with
respect to, this Agreement or any other Loan Document, except to the extent such
amendment, consent or waiver would:

              (A)  increase the amount or extend the Maturity Date of the 
Commitment;

              (B)  reduce the principal of, or interest on, the Revolving Loans 
or any fee or other amount payable to the participant hereunder;

              (C)  postpone any date fixed for any payment in respect of 
principal of, or interest on, the Revolving Loans or any fee or other amount
payable to Bank hereunder; or

              (D)  amend the provisions of this sentence.

In the event that Borrower requests a modification to any of the provisions set
forth in clauses (A) through (D) above (a "Modification Request") and any
existing participant refuses to agree to such modifications (a "Nonaccepting
Participant"), Bank shall use good faith efforts to secure a participant willing
to accept such modifications as a replacement participant for the Nonaccepting
Participant (an "Accepting Participant") and, in the event that Bank shall be
unable to secure an Accepting Participant within 60 days from Bank's receipt
from Borrower of the related Modification Request, then 



                                      -41-
<PAGE>   45
Borrower shall, at its option, be entitled to purchase the Nonaccepting
Participant's participation interest. No participant shall constitute "Bank"
under any Loan Document, and Borrower shall continue to deal solely and directly
with Bank.

         (b)  Bank may disclose to any proposed participant which is a financial
institution any information relating to Borrower or any of its Consolidated
Subsidiaries; provided, that prior to such disclosure such participant and Bank
shall have executed Borrower's standard Confidential Disclosure Statement
("Confidentiality Letter").

    VIII.7.   EFFECTIVENESS, BINDING EFFECT; GOVERNING LAW. This Agreement is 
being executed on the date hereof by Borrower, and Bank and is binding on and

thereafter shall be binding upon and inure to the benefit of Borrower, Bank and
their respective permitted successors and assigns, except that Borrower shall
not have the right to assign its rights hereunder or any interest herein without
the prior written consent of Bank. THIS AGREEMENT AND THE REVOLVING NOTE SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
CALIFORNIA WITHOUT GIVING EFFECT TO ITS CHOICE OF LAW DOCTRINE.

    VIII.8.   CONSENT TO JURISDICTION; VENUE. BANK FOR SERVICE OF PROCESS. All
judicial proceedings brought against Borrower with respect to this Agreement and
the Loan Documents may be brought in any state or federal court of competent
jurisdiction in the County of San Francisco in the State of California, and by
execution and delivery of this Agreement, Borrower accepts for itself and in
connection with its properties, generally and unconditionally, the nonexclusive
jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any
judgment rendered thereby in connection with this Agreement. Borrower
irrevocably waives any right it may have to assert the doctrine of forum non
conveniens or to object to venue to the extent any proceeding is brought in
accordance with this Section. Borrower designates and appoints Borrower's Chief
Financial Officer, from time to time, Komag Incorporated, 275 South Hillview
Drive, Milpitas, California 95035, and such other Persons as may hereafter be
selected by Borrower irrevocably agreeing in writing to so serve (as its agent
to receive on its behalf 


                                      -42-
<PAGE>   46
service of all process in any such proceedings in any such court, such service
being hereby acknowledged by Borrower to be effective and binding service in
every respect). A copy of any such process so served shall be mailed by
registered mail to Borrower at its address provided in the applicable signature
page hereto, except that unless otherwise provided by applicable law, any
failure to mail such copy shall not affect the validity of service of process.
If any agent appointed by Borrower refuses to accept service, Borrower hereby
agrees that service upon it by mail shall constitute sufficient notice. Nothing
herein shall affect the right to serve process in any other manner permitted by
law or shall limit the right of Bank, on behalf of Bank or Bank to bring
proceedings against Borrower in courts of any jurisdiction.

    VIII.9.   ENTIRE AGREEMENT. This Agreement with Exhibits and the other Loan
Documents embody the entire agreement and understanding between the parties
hereto and supersedes all prior agreements and understandings relating to the
subject matter hereof.

    VIII.10.  SEPARABILITY OF PROVISIONS. In case any one or more of the 
provisions contained in this Agreement should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

    VIII.11.  EXECUTION IN COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement.

    VIII.12.  SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and 
inure to the benefit of the parties hereto and their respective successors and
assigns, except that Borrower may not assign or transfer any of its rights or
obligations under this Agreement or any other Loan Document without the consent
of Bank.

    VIII.13.  EFFECTIVENESS OF AGREEMENT. This Agreement shall become effective 
on the later to occur of (i) December 15, 1995 and (ii) such other date that
Borrower notifies Bank that any necessary approvals of any other lenders to

if this Agreement 


                                     -43-
<PAGE>   47
has not become effective on or before January 31, 1996 as hereinabove provided,
