                                     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
used in computer  hard disk  drives.  Komag  believes it is the world's  largest
independent  manufacturer  of  thin-film  media  and  is  well  positioned  as a
broad-based  strategic  supplier of choice for the industry's leading disk drive
manufacturers.  The Company's  business  strategy  relies on the  combination of
advanced technology and high-volume manufacturing.  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  leading-edge  disk
products  primarily  for 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 drives has resulted in strong unit demand for these products. International
Data Corporation  ("IDC")  forecasts that worldwide disk drive unit shipments in
1997  through  2000 will grow at a 20%  compound  annual  growth  rate.  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
three to nine gigabytes (one billion bytes is a gigabyte or "GB") with densities
typically  of 650  to 850  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  and  maintain  its
position as the leading independent  supplier to 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").


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 10,000 RPM.  The head scans across the
disk as it spins,  magnetically  recording or reading  information.  The domains
where each bit of magnetic code is

                                       3
<PAGE>

stored are  extremely  small (now  typically  650 to 850 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").  As glide height is
reduced,  smaller bits can be read. 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 fly over the disk surface at
glide heights of 1.2 microinches.  The platinum-cobalt  based alloy deposited on
the surfaces of Komag's disks has high coercivity, 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.

     The Company currently  manufactures  inductive and magnetoresistive  ("MR")
media.  Designed for use with an MR head,  magnetic bits are reduced in size and
packed in  significantly  higher  densities on the surface of an MR disk than on
inductive  disks.  The MR head uses separate read and write elements.  The write
element is made from conventional inductive materials, but the read element is a
made of a material whose electrical resistance changes when subjected to changes
in a magnetic  field.  MR heads are more  sensitive  to  magnetic  fields  which
enables them to read the more densely-packed, smaller-sized bits contained on an
MR disk. The Company  believes that MR disks will become the  predominant  media
for disk  drives  over the next  several  years.  In  1996,  the  Company  began
production of MR media. The Company also currently manufactures proximity media,
an  advanced  version  of  inductive  media.  Proximity  media  interfaces  with
proximity  recording  heads and allows for higher  density  recording due to low
glide heights attainable with proximity media and heads.


Products, Customers and Marketing

     Komag's  thin-film  disk  products  generally can be classified by size and
type of media.  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.  The  Company  currently  sells
inductive,  proximity  and MR  media.  Within  each of these  sizes and types of
media,  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 1996 were as follows:  Seagate Technology,
Inc. ("Seagate")--52%,  Western Digital Corporation ("Western Digital")--22% and
Quantum Corporation  ("Quantum") including its Japanese  manufacturing  partner,
Matsushita-Kotobuki   Electronics  Industries,  Ltd.  ("MKE")--18%.   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
other  disk   drive   components.   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
were  consolidations  among the Company's disk drive customers in 1996.  Seagate
and Conner Peripherals, Inc. merged and Quantum ceased disk drive

                                        4

production in Milpitas,  California and Penang, Malaysia and contracted with MKE
to  manufacture  all of its disk drives.  AKCL,  the  Company's  Japanese  joint
venture,  has a long  established  working  relationship  with  MKE  and MKE has
remained  AKCL's largest  customer for the past several  years.  During 1996 the
Company  sold  product  to MKE in  Japan  and to MKE's  Singapore  manufacturing
facility through AKCL.

     Sales are made directly to disk drive manufacturers worldwide (except media
sales into Japan) from the  Company's  U.S. and Malaysian  operations.  Sales of
media for assembly into disk drives  within Japan are made solely  through AKCL.
On a selective  basis the Company has used AKCL to  distribute  its  products to
Japanese drive  manufacturers for assembly outside of Japan.  Media sales to the
Far East from the Company's U.S. and Malaysian  operations  represented 88%, 62%
and 54% of Komag's net sales in 1996, 1995 and 1994,  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 29, 1996 the Company's
backlog of purchase orders  scheduled for delivery within 90 days totaled $113.0
million compared to $156.0 million at December 31, 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 more prevalent in 1995 in comparison to 1996).  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 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.

      The manufacture of the Company's  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. Sizing and Grinding of the Substrate:  A raw aluminum blank substrate is
sized by  precisely  cutting  the inner  and  outer  diameter  of the  blank.  A
mechanical  grinding  process  is then  utilized  to provide a  relatively  flat
surface on the substrate prior to nickel alloy plating.

                                        5
<PAGE>

     2.  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.

     3.  Nickel  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.

     4.  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.

     5. 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,  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  23  production   lines   installed  at  its
manufacturing  plants in three  countries:  ten in the United  States,  eight in
Malaysia,  and five at its manufacturing joint venture in Japan. The addition of
the seventh line in the second quarter of 1996 in Penang,  Malaysia utilized all
available space in the Company's  first Penang  manufacturing  facility.  During
1996 the Company completed the construction of the second manufacturing facility
in Penang and  production  began on the first line in this  275,000  square foot
back end disk  manufacturing  facility in early January  1997.  The Company also
completed  construction  of a new back end facility in San Jose,  California and
production  commenced at this 225,000 square foot facility in the fourth quarter
of 1996.  The Company  constructed  and equipped a 275,000 square foot front end
manufacturing  facility  in the east  Malaysian  state of  Sarawak  which  began
production  in  the  first  half  of the  year.  This  new  front  end  facility
manufactures plated,  polished substrates that are shipped to the Company's back
end  manufacturing  facilities in the United States and Malaysia for completion.
The back end plants  utilize  plated,  polished  substrates to produce  finished
sputtered disk product. AKCL completed the construction of a 225,000 square foot
facility in  Thailand  for front end  production  of  thin-film  disks and began
production at this site in late 1996.

     The  Company  currently  plans to add a second  production  line at the new
Penang plant in the second  quarter of 1997. In addition,  in the second quarter
at the new San Jose plant, the Company plans to commence production on the first
new design ("ND")  sputtering  machine which will have a rated capacity of twice
the output of the Company's existing machines.  In the third quarter the Company
will add a ND machine at its new Penang plant.  The addition of these production
lines in the second and third  quarters of 1997,  coupled with the first line in
the new Penang plant,  will translate into the equivalent of six more sputtering
lines by the end of the third quarter of 1997 than at the end of 1996.  Also, in
1997 the Company will  complete the equipping  and  production  expansion of the
front end manufacturing facility in Sarawak, Malaysia.

                                       6
<PAGE>

     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 1997, 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 were upgraded.  Three U.S. machines were upgraded
in 1995 and three machines were upgraded in 1996.  Only one sputtering  line was
out of  production  at any given time.  Certain  older  sputtering  lines at the
Japanese  joint  venture were also upgraded  during 1995 and 1996.  This upgrade
process  is now  complete,  however,  there  can  be no  assurance  that  future
modifications will not be required to meet new product needs.


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 has utilized a full scale  sputtering line for pilot
production. The Company has recently completed the construction of a new 188,000
square foot research and development  facility which the Company occupied in the
first quarter of 1997. The new facility is being equipped with an additional new
full scale  sputter line which will be  dedicated  to research  and  development
activities  and available for use in the second  quarter of 1997.  The Company's
spending  and  capital  investment  for R&D are  focused  on the  investigation,
design,  development,  and testing of new products and  processes as well as the
development   of  more  efficient   processes   that  can  be  integrated   into
manufacturing in a commercially viable manner.

     In the second  half of 1996,  the Company  completed  the  development  and
quickly ramped to volume  production new proximity and  magnetoresistive  ("MR")
products.  The new  proximity  products  are  low-glide,  full-surface  textured
inductive media for use with proximity  heads. The new MR products are comprised
of  full-surface  and  mechanical  zone-textured  MR  media  as  well  as  laser
zone-textured media for use with MR recording heads.

     In 1997,  the Company  plans to increase its R&D spending to  approximately
$50  million.  The  Company's  R&D  team  will  focus  on  process  changes  and
improvements  to increase  yields on the proximity and MR products  currently in
volume  production.  New proximity and MR products will continue to be developed
and glass media  products will be developed for  production in late 1997.  These
advanced  products  require new and continuing  development  efforts and process
improvements  in the front end  manufacturing  processes from substrate  through
nickel polish, as well as improved cleaning processes,  improved overcoats,  and
improved  magnetic  recording  characteristics  for the  magnetic  layers on the
disks.

     The  Company's   expenditures   (and  percentage  of  sales)  on  research,
development  and  engineering,  were $29.4 million (5.1%) in fiscal 1996,  $23.8
million (4.6%) in fiscal 1995, and $21.3 million (5.4%) in fiscal 1994.


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,

                                        7
<PAGE>

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 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,  thus offsetting the incremental unit output from the newly-installed
fifth sputtering line. The second  sputtering line was upgraded during the first
half of 1996 and all sputtering lines were in production  during the second 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. 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. The Company has, however,  periodically granted AKCL a limited right to
sell its disks outside of Japan and has received  royalties on such sales.  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  6% of the  Company's  net  sales in 1996
compared to less than 1% in 1995 and 1994. The increased  level of disk sales by
the Company to AKCL for  distribution  is  expected  to  continue  in 1997.  The
Company purchased 3% of AKCL's unit output during 1996 compared to approximately
1% and 8% in 1995 and 1994,  respectively.  Demand within the Japanese thin-film
disk  market  continued  to  absorb  most  of  AKCL's  production.  The  Company
anticipates that distribution sales of AKCL-produced  disks to U.S. customers in
1997 will remain a relatively small percentage of the Company's net sales.

     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  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 these  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 95% of the Company's substrate requirements.

     Equity Positions Held by Asahi Glass and Kobe in Komag

     Asahi  Glass and Kobe each  purchased  two 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 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.  There were no  purchases  or sales of the  Company's  stock by Asahi
Glass or Kobe in 1996 and according to the  Company's  stock records at February
21, 1997,  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 Japanese/Asian  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
independent  supplier of thin-film disks, with a market share greater than twice
the  size of any of the  U.S.  non-captive  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 disk drive manufacturers,  such as Seagate and
Western Digital, which manufacture disks as a part of their vertical integration
programs.  To date, IBM and these OEM disk 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
Technologies,  Inc.,  ("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

                                       9
<PAGE>

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 are 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 29, 1996 the Company and its  consolidated  subsidiaries had
4,101  employees  (4,027 of which are  regular  employees  and 74 of which  were
employed  on a  temporary  basis),  including  3,708  in  manufacturing,  222 in
research,  development and  engineering,  and 171 in sales,  administrative  and
management positions. Of the total, 2,035 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

                                       10

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:
the  rate  of  improvement  in  manufacturing   efficiencies  on  new  products;
utilization of manufacturing  equipment and facilities;  product  transitions to
next-generation  products;  industry  supply-demand  relationships  and  related
pricing for high-end desktop and enterprise disk products;  execution of planned
capacity  additions;  availabilty of certain  sole-sourced raw material supplies
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.  Through these  reviews,  the Company  occasionally  becomes
aware of a patent, or an application that may mature into a patent,  which could
give rise to a claim of  infringement.  When such  patents are  identified,  the
Company  investigates the validity and possibility of actual  infringement.  The
Company is  presently  involved  in such an  investigation  of several  recently
issued patents. However, the Company presently believes it is unlikely that such
patents will materially  adversely affect the Company's  business.  However,  if
such  patents are  asserted  against  the  Company  and upheld,  there can be no
assurance  that they would not apply to a  significant  portion of the Company's
products and would not have a material adverse effect on the Company's business.

Capacity Expansion and Capital Intensity

     Future sales and earnings  growth will depend,  in part, 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 its
manufacturing facilities. In the second half of 1996, low yields on new products
and  high  usage  of  production  lines  for  product  and  process  development
activities constrained unit output. If planned improvements in yields, equipment
utilization  and process  cycle times are not achieved,  the  Company's  rate of
growth may be constrained or curtailed.

                                       11
<PAGE>

     The  Company  recently  completed  the  construction  of two new  back  end
production facilities,  one in San Jose, California and one in Penang, Malaysia.
The first  production  line at the new San Jose facility began  operation in the
fourth quarter of 1996.  The first  production  line at the new Penang  facility
began  operation at the beginning of 1997. The Company  currently plans to add a
second production line at the new Penang plant in the second quarter of 1997. In
addition,  in the second quarter at the new San Jose plant, the Company plans to
commence production on the first new design ("ND") sputtering machine which will
have a rated capacity of twice the output of the Company's existing machines. In
the third  quarter the Company will add a ND machine at the Penang  plant.  Also
the Company will complete the equipping  and  production  expansion at the front
end manufacturing plant in Sarawak, Malaysia. There can be no assurance that the
Company's  additional  production  lines,   especially  the  new  ND  sputtering
machines,  will be installed  as scheduled or will attain yield and  utilization
rates comparable to the Company's existing  production lines.  Manufacturing and
other challenges in connection with the commencement and subsequent expansion of
operations in any location 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 and is executing its plan 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.  Under this more  aggressive  plan, the
Company  successfully  completed the  construction  and brought into  production
three new  manufacturing  facilities on schedule  during the last twelve months.
Continued   successful  execution  of  this  expansion  plan  will  require  the
installation of the appropriate equipment to support current and advanced future
products,  continued recruitment and retention of high quality workforces at all
facilities worldwide, and achievement of satisfactory manufacturing results on a
scale greater than the Company's prior expansions.

     The Company's capital expenditures totaled $403 million in 1996 and capital
expenditures  for 1997 are planned at  approximately  $290  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  are  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 equipment currently in use.

     There  can be no  assurance  that the  Company  will  successfully  achieve
planned process  improvements or  successfully  manage its aggressive  expansion
plan.  Failure to improve  yields from the low levels  experienced in the fourth
quarter of 1996 would  continue to  materially  adversely  effect the  Company's
results of  operations.  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 1996  were as  follows:  Seagate--52%,  Western  Digital--22%  and
Quantum,  including  its  Japanese  manufacturing  partner  MKE--18%.  Given the
relatively  small  number of  high-performance  disk  drive  manufacturers,  the
Company expects that it will continue its dependence on a very

                                       12
<PAGE>

limited  number  of  customers.  Further  there  were  consolidations  among the
Company's  disk drive  customers in 1996.  Seagate and Conner merged and Quantum
ceased disk drive  production in Milpitas,  California and Penang,  Malaysia and
contracted with MKE to manufacture  all of its disk drives.  AKCL, the Company's
Japanese joint venture, has a long established working relationship with MKE and
MKE has remained AKCL's largest customer for the past several years. During 1996
the Company  sold product to MKE in Japan and to MKE's  Singapore  manufacturing
facility through AKCL.

     Seagate currently produces over 50% of its disk requirements internally and
has  announced its  intentions to produce at least 70% of its internal  needs by
mid-1997.  In addition,  Seagate currently has a long-term  purchase  commitment
with one of the  Company's  competitors.  Western  Digital has stated its longer
term  intention to grow internal  media capacity from under 30% to at least 40%.
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  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  growth
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 spent  approximately  $403 million on property,  plant and equipment
and capital  expenditures in 1997 are expected to approximate $290 million.  The
Company  believes  that it will be able to fund  the  1997  expenditures  from a
combination  of cash flow from  operations,  funds  available from existing bank
lines of credit,  and existing cash  balances.  However,  the Company may obtain
additional  debt or equity  financing  in 1997 to ensure the  Company  maintains
adequate cash  reserves.  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.

                                       13
<PAGE>

     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  cause declines in gross  margins.  Additionally,  decreasing  market
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 first and second  quarters of 1996, the Company  achieved high gross margins
as a result of high  manufacturing  efficiencies,  coupled  with  strong  market
demand for its  inductive  disk  products.  In the third and fourth  quarters of
1996, the Company made a rapid transition to new proximity and MR disk products.
The lower yields on these new  products,  coupled with high usage of  production
equipment  for product  and process  development  activities,  constrained  unit
output in the second half of the year.  In light of the fixed cost nature of the
business,  constrained  unit  output  resulted  in high unit costs and low gross
margins in the second half of the year.  The Company  expects  gross  margins to
improve  sequentially  in the first two quarters of 1997 from the fourth quarter
1996 level and has  targeted a gross  margin range of 30-35% for the second half
of 1997.  In the event that market  supply meets or exceeds  demand or yields on
new  products do not improve at the rate  expected,  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,  also impact the Company's financial
performance.  Equity in net income of AKCL  contributed 9% of the Company's 1996
consolidated  net  income.  AKCL is  subject  to many of the same types of risks
facing the Company  including the risks associated with a similar  transition to
MR products which AKCL began in the second half of 1996. In addition, the equity
income  derived from AKCL  fluctuates  over time due to its dependence on a more
limited customer base (MKE, Fujitsu Ltd. and Toshiba  Corporation  accounted for
61%, 19% and 16% respectively, of AKCL's 1996 net sales) and yen/dollar exchange
rate fluctuations.  AKCL's financial results were also impacted in 1996 and 1995
by write-downs of its investment in Headway Technologies, Inc. ("Headway"). AKCL
sold its  interest  in Headway in the first  quarter of 1997 and will  include a
gain on sale of the investment in its first quarter 1997 operating results.

Risk of Foreign Operations

     In 1996 sales to customers in the Far East,  including foreign subsidiaries
of domestic  companies,  accounted  for 88% 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  Malaysian  operations in Penang and Sarawak  accounted for a
significant  portion of the Company's 1996  consolidated net sales and operating
income.  Prolonged  disruption  of  operations  in Penang and or Sarawak for any
reason  would  cause  delays  in  shipments  of  the  Company's  products,  thus
materially adversely affecting 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. However, if the technology involved in the manufacture of thin-film
disks does not  continue  to advance  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 approximately 22% in 1996 over 1995 and
are projected to grow at a 20% compound  annual growth rate in 1997 through 2000
according  to  International  Data  Corporation  ("IDC").  In  response  to  the
continuing rapid growth of the disk drive market and resulting strong demand for
thin-film  disk  products,  the Company as well as a majority  of the  Company's
competitors (both independent disk manufacturers and vertically-integrated  disk
drive customers) are substantially increasing their disk manufacturing capacity.
The Company  believes that its  manufacturing  operations in Penang and Sarawak,
Malaysia  have  provided a  competitive  cost  advantage  relative to most other
thin-film  disk  manufacturers  that operate  exclusively in the U.S. and Japan.
However,  in order to remain cost competitive,  many of the U.S. and Japan based
competitors are currently expanding into lower cost regions in the world such as
Southeast Asia. These  significant  investments in new disk production  capacity
could result in an oversupply of disk media and increase  price  competition  in
the media market.  Further,  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  and  equipment  used  in  its  manufacturing
processes.   These  materials  include  aluminum   substrates,   nickel  plating
solutions,  certain  polishing  and  texturing  supplies and  sputtering  target
materials.  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.

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:  the
rate of improvement in manufacturing  efficiencies on new products;  utilization
of manufacturing  facilities;  product transitions to next-generation  products;
industry supply-demand relationship and related pricing for high-end desktop and
enterprise  disk products;  availability  of certain  sole-sourced  raw material
supplies;  vertical  integration and consolidation  within the Company's limited
customer base; and execution of planned capacity additions.  See "Business--Risk
Factors" for more detailed discussions of the Company's risk factors.

1996 vs. 1995

         Product  transitions were significant factors in both the 1995 and 1996
fiscal years. In 1995, the Company transitioned to its then-current leading-edge
inductive  disk product  family.  Quarterly  sales and gross  margins  increased
sequentially  during 1995 from $105.1  million and 31.2%,  respectively,  in the
first quarter of 1995 to $153.5 million and 42.6%,  respectively,  in the fourth
quarter of 1995. The Company entered 1996 with continuing  strong demand for its
inductive  media  products.  Quarterly sales in excess of $150 million and gross
margins  exceeding  40% in both the first and  second  quarters  of 1996 were at
near-record  levels for the  Company.  During the third and fourth  quarters  of
1996,  the  Company  began a rapid  transition  to two  distinctly  new  product
families--proximity   media  (an  advanced   version  of  inductive  media)  and
magnetoresistive ("MR") media. Sales and gross margins decreased during the last
half of 1996 as low manufacturing yields on these new products and high usage of
production  equipment for product and process development  activities  prevented
the Company  from  fulfilling  customer  demand for the  products.  In the third
quarter of 1996,  net sales and gross  profit  decreased  to $131.5  million and
24.0%.  Net sales and gross profit were $141.2  million and 11.7% for the fourth
quarter of 1996.  During the fourth quarter of 1996, the Company achieved volume
production of MR disk  products and also  increased  the  production  volume for
proximity  products.  These two new products accounted for 54% of unit shipments
during the fourth quarter.

Net Sales

         Net sales for 1996  increased  to $577.8  million,  up 13% from  $512.2
million in 1995.  Net sales during 1996 included $6.5 million of substrate  disk
sales; no such substrate sales occurred in 1995. The

                                       22
<PAGE>

Company  may  periodically  sell  substrate  products  but  does  not  currently
anticipate  that such sales will become a  significant  portion of its  revenue.
Excluding the substrate disk sales,  net sales  increased 12% between the years.
The higher  sales  resulted  from the net effect of a 21% increase in unit sales
volume and an 8% decrease  in the overall  average  selling  price.  The overall
average  selling  price  typically  strengthens  only as the  result of  product
transitions to higher-priced,  more technologically  advanced product offerings.
Price  reductions for individual  product  offerings are  characteristic  of the
thin-film  media industry.  The Company  rapidly  transitioned to higher oersted
inductive products  throughout 1995. Unit sales of these products increased from
41% of net sales in the first  quarter of 1995 to 91% of net sales in the fourth
quarter of 1995.  Unit sales of these products  continued to exceed 90% of sales
during the first half of 1996. During the third and fourth quarters of 1996, the
Company began a transition to two new product  families--proximity  media and MR
media. The effects of price reductions on maturing  inductive disk products were
only  partially  offset  by  the  product  mix  shift  to  these  higher-priced,
next-generation products.

         In addition to sales of 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  increased  to $5.7  million in 1996 from $0.9  million in
1995. The Company  anticipates that distribution sales of AKCL-produced goods to
U.S.  customers  in 1997  will  remain  a  relatively  small  percentage  of the
Company's net sales.

         Increased  production  volume  may  occur  due  to  increased  physical
capacity  (additional  production  lines) and/or  improvements in  manufacturing
efficiencies   (improved  production   throughput  from  higher  yields,  better
equipment  utilization  or shorter  process cycle  times).  The increase in unit
production  required  to support  the  increase  in unit  sales  volume for 1996
relative  to 1995 was  primarily  achieved  through the  addition of  production
lines.  The  Company  added one new  sputtering  machine in each of March  1995,
September  1995,  January 1996,  May 1996 and November 1996. At the end of 1996,
the Company had ten and seven  production  lines in  operation  in the U.S.  and
Malaysia,  respectively.  Improvements  in process  cycle  times  only  slightly
outpaced decreases in manufacturing yields and equipment utilization between the
years and  resulted in a marginal  improvement  in  manufacturing  efficiencies.
Manufacturing  yields and  equipment  utilization  decreased  between  the years
mainly due to substantially  lower yield and utilization  rates in the last half
of 1996 on the new MR and proximity product families. Development time for these
new  products,  incurred  on  manufacturing  lines,  lowered  the  manufacturing
equipment utilization rate in the last half of 1996.

         The Company  plans to increase  production  capacity  for the first and
second quarters of 1997 through the addition of three new production  lines. One
of these lines,  the first new design  ("ND")  sputtering  machine,  will have a
rated  capacity  equal to twice the output of the Company's  existing  machines.
During the second half of 1997,  the Company  expects to add one  additional  ND
machine.


Gross Margin

         The gross margin  percentage for 1996 decreased to 30.4% from 38.6% for
1995. The  combination of an 8% decrease in the overall  average  selling price,
lower yield and equipment  utilization rates in the last half of 1996 and higher
costs associated with the production of the new MR and advanced  proximity disks
resulted in the lower gross margin percentage.  The Company anticipates that its
overall  average  selling price will likely  increase  through the first half of
1997 as it continues  to  transition  its sales mix toward these  higher-priced,
more  technologically  advanced  products.  While the Company expects  continued
yield  improvement in 1997,  the rate of yield  improvement on new products will
likely  continue to constrain  financial  results during the first half of 1997.
The Company believes gross margins will show sequential  improvement  during the
first two  quarters of 1997 and is  targeting a gross margin range of 30-35% for
the second half of the year.

                                       23

Operating Expenses

         Research and development  ("R&D") expenses increased 24% ($5.6 million)
in 1996 relative to 1995.  The increase was primarily due to  development  costs
associated with  next-generation  proximity and MR media  products.  The Company
plans to increase its R&D  spending to  approximately  $50 million in 1997.  The
increase is  primarily  due to the  installation  of a  sputtering  line devoted
exclusively  to R&D  efforts,  completion  of an R&D  facility,  and  additional
staffing.  The  Company  expects  to fully test and  develop  new  products  and
processes  on  the  R&D  sputtering  line  prior  to  their   introduction  into
manufacturing.  Use of the dedicated R&D sputtering line for  large-scale  pilot
production runs will limit the use of existing  manufacturing  production  lines
for  this  purpose.   Selling,  general  and  administrative  ("SG&A")  expenses
decreased $10.9 million in 1996 compared to 1995. The decrease was primarily due
to a $12.0 million reduction in the provision for the Company's bonus and profit
sharing  programs.  Lower provisions in 1996 were primarily due to the Company's
1996  operating  profit  performance  relative to the Company's  1996  operating
profit plan.  Provisions for bad debt also  decreased  $2.5 million  between the
years.  Excluding  provisions  for bad debt and the  Company's  bonus and profit
sharing programs, SG&A expenses increased approximately $3.6 million.  Increases
in administrative costs required to support the growth in operations in both the
U.S. and Malaysia accounted for the increase.


Interest Income/Expense and Other Income

         Interest  income  increased $0.6 million (11%) in 1996 relative to 1995
primarily due to a higher average investment  balance in 1996.  Interest expense
decreased  $1.2 million in 1996 compared to 1995.  The Company repaid all of its
existing  outstanding  debt in  September  1995 and  remained  debt  free  until
November  1996. The Company  borrowed $70.0 million under its credit  facilities
during November and December 1996.  Other income  increased $0.7 million in 1996
relative to 1995 mainly due to the commencement of a royalty from AKCL for sales
AKCL made  outside of Japan.  The  royalty  began in the second half of 1996 and
amounted to $1.3 million for the year.


Income Taxes

         The  effective  income tax rate for 1996 of 17% was lower than the 1996
combined  federal and state  statutory rate of 41% and the effective  income tax
rate of 25% in 1995  primarily as a result of an initial  five-year  tax holiday
granted to the  Company's  wholly owned  thin-film  media  operation,  Komag USA
(Malaysia)  Sdn.  ("KMS"),  which  commenced in July 1993.  Assuming the Company
fulfills certain commitments under its license to operate within Malaysia,  this
initial tax holiday may be extended for an  additional  five-year  period by the
Malaysian government. The effective tax rate for 1996 was lower than the rate in
effect for 1995 primarily due to growth in the percentage of consolidated income
derived from the Company's  Malaysian  operations in 1996. The impact of the tax
holiday was to increase net income by  approximately  $21.8  million  ($0.41 per
share)  and $11.5  million  ($0.23  per  share) in 1996 and 1995,  respectively.
Losses  incurred  prior  to  the  commencement  of  this  initial  tax  holiday,
approximately  $6.2 million,  are available for  carryforward to years following
the  expiration  of this tax  holiday.  The  Company  has also been  granted  an
additional  ten-year tax holiday for new  operations  in Malaysia.  This new tax
holiday has not yet commenced at December 29, 1996.


Minority  Interest in Consolidated  Subsidiary/Equity  in  Unconsolidated  Joint
Venture

         The  minority  interest  in the net income of  consolidated  subsidiary
during 1996  represented  Kobe Steel USA Holdings  Inc.'s  ("Kobe USA") share of
Komag Material  Technology,  Inc.'s ("KMT") net income. KMT was owned 55% by the
Company and 45% by Kobe USA from November 1988 to December 1995. On December 28,
1995, the Company increased its ownership of KMT to 80% through

                                       24
<PAGE>

the purchase of KMT Common Stock  directly  from Kobe USA.  Kobe  retained a 20%
minority interest investment in KMT. KMT recorded net income of $3.5 million and
$4.3 million in 1996 and 1995, respectively.

         The Company records 50% of AKCL's net income as equity in net income of
unconsolidated  joint  venture.  AKCL  reported net income of $20.2  million for
1996, up from $14.7 million for 1995. AKCL's results included  writedowns of its
investment in Headway  Technologies,  Inc.  ("Headway") of $4.5 million and $2.2
million (net of tax) in 1996 and 1995, respectively. AKCL invested in Headway in
1994 and recorded partial  writedowns of its investment  through 1995 based upon
net losses  incurred by  Headway.  During the third  quarter of 1996,  Headway's
major customer, Hewlett-Packard Company ("HP") announced the closure of its disk
drive manufacturing  operations.  Based upon anticipated future operating losses
at Headway arising from the loss of HP's business,  AKCL wrote-off its remaining
Headway  investment  at the end of the  third  quarter  of 1996.  Subsequent  to
year-end,  AKCL sold its entire interest in Headway for $10.8 million to a group
of new investors as part of a recapitalization.  AKCL recorded the proceeds from
this sale as a gain ($5.3 million, net of tax) in the first quarter of 1997. The
Company  will  reflect  its 50% share of this net gain in the first  quarter  of
1997.

         Excluding losses related to Headway,  AKCL recorded net income of $24.7
million  in 1996,  up from  $16.9  million in 1995.  AKCL's  improved  operating
performance  in 1996 was primarily due to the  combination of an increase in the
overall  average  selling  price of its  products and a reduction in the overall
average  unit  production  cost on a  substantially  higher  unit sales  volume.
Despite the improved year-to-year results, AKCL's quarterly net income decreased
substantially  from $6.1  million in the third  quarter of 1996  (excluding  the
Headway  write-off) to $0.8 million in the fourth  quarter of 1996. The decrease
was primarily due to new product  transition issues similar to those experienced
by the Company.  Manufacturing  yield and utilization issues associated with the
product  transition  lowered AKCL's production  quantity to 2.6 million units in
the fourth quarter of 1996,  down from 4.3 million units in the third quarter of
1996.

         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 weakened  approximately  13% in 1996  relative to 1995.  AKCL's net
income would have been  approximately  $23.9  million in 1996 had the  yen-based
income statement been translated at the average rate in effect for 1995.


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. The Company began a rapid transition to high oersted inductive
product  offerings  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 high oersted
inductive products 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.  Distribution sales of product manufactured by AKCL
decreased to $0.9 million in 1995 from $9.4 million in 1994.

         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.

                                       25
<PAGE>

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 high oersted  inductive  products in 1995,  strong industry demand
for this product,  and solid manufacturing  performance resulted in the improved
gross margin percentage.  The higher overall average selling price accounted for
over two-thirds of the gross margin percentage increase.  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 inductive products.

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  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.

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  provided by proceeds  from the  Company's
third public offering in September 1995. Interest expense decreased $1.1 million
(37%) in 1995  compared to 1994  primarily  due to a lower average debt balance.
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
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.  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  $11.5 million  ($0.23 per share) and $6.4 million  ($0.14 per
share) in 1995 and 1994, respectively.

Minority  Interest in Consolidated  Subsidiary/Equity  in  Unconsolidated  Joint
Venture

         The  minority  interest  in the net income of  consolidated  subsidiary
during 1995 represented  Kobe USA's 45% share of KMT's net income.  KMT recorded
net income of $4.3 million and $2.4 million in 1995 and 1994, respectively.

         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.  AKCL's net income  reflected  writedowns,
net of tax, of its  investment  in Headway of $2.2  million and $0.5  million in
1995 and 1994,  respectively.  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.

Liquidity and Capital Resources

         Consolidated  cash and  short-term  investments of $93.2 million at the
end of 1996  decreased  substantially  from  $213.7  million at the end of 1995.
Operating  activities generated $200.9 million in cash during 1996 and partially
funded the Company's  $403.1  million of capital  spending  during the year. The
Company  borrowed  $70.0  million under its credit  facilities.  Sales of Common
Stock under the Company's  stock option and stock purchase  programs  during the
year generated $10.8 million. Working capital decreased to $142.1 million at the
end of 1996 from $252.2  million at the end of 1995.  The decrease was primarily
due to the lower cash and short-term investment balances. Trade accounts payable
and accounts  payable to related parties  increased $46.9 million as a result of
the higher  level of capital  spending in 1996.  Inventory  balances,  including
inventory  intransit  between  the  Company's  U.S.  and  Malaysian  facilities,
increased $32.9 million primarily due to the addition of offshore  manufacturing
capacity.

         Total  capital   expenditures   for  1997  are  currently   planned  at
approximately  $290 million.  The 1997 capital  spending plan includes  costs to
equip the Company's two recently completed back end manufacturing  facilities in
Penang,  Malaysia and San Jose, California.  Additionally,  the Company plans to
complete and equip a 188,000 square foot research and development facility and a
82,000 square foot administration building in San Jose, California for occupancy
in the first quarter of 1997.

         Current  noncancellable  capital commitments total approximately $104.0
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 for capital expenditures, working capital, and research and
development.  The  Company  believes  that it will  be  able  to fund  its  1997
expenditures  through a combination  of cash generated  from  operations,  funds
available  from  existing  bank lines of credit,  and  existing  cash  balances.
However,  the Company may obtain  additional debt or equity financing in 1997 to
maintain  adequate cash reserves.  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 29, 1996 and  December  31,  1995,  and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three  years in the period  ended  December  29,  1996.  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 29, 1996 and December 31, 1995, and for each of the
three years in the period ended December 29, 1996.  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 29, 1996 and December 31, 1995,  and for each of the three years in the
period  ended  December  29,  1996,  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 29, 1996
and December 31, 1995, and the  consolidated  results of its income and its cash
flows for each of the three years in the period  ended  December  29,  1996,  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.

                               KOMAG, INCORPORATED
                   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
Note 11) and  equity in its  unconsolidated  joint  venture  (see Note 12).  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  $10,320,000 and $17,125,000 in foreign
exchange  forward  purchase  contracts  outstanding  at  December  29,  1996 and
December 31, 1995, respectively. These forward exchange contracts were comprised
of Yen, Malaysian  Ringgit,  and Singapore Dollar foreign  currencies.  The fair
market value of these foreign  exchange  contracts was not materially  different
from the  contract  value at December 29,  1996.  The Company had  approximately
$358,000 of unhedged  Japanese  yen-based firm purchase  commitments at December
31, 1995. There were no such unhedged purchase commitments at December 29, 1996.

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.  None of the Company's debt security  investments
have  maturities  greater than one year.  At December 29, 1996,  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 1996
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 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.

Stock  Compensation:  The Company has adopted Statement of Financial  Accounting
Standard No. 123,  "Accounting  for  Stock-Based  Compensation"  ("FAS 123"). In
accordance  with the  provisions of FAS 123, the Company  applies APB Opinion 25
and related  Interpretations  in  accounting  for its  stock-based  compensation
plans. Note 5 to the Consolidated Financial Statements contains a summary of the
pro forma  effects to reported  net income and  earnings  per share for 1996 and
1995 as if the Company had elected to recognize  compensation  cost based on the
fair value of the options granted at grant date as prescribed by FAS 123.

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 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.

Fiscal  Year:  The  Company  uses a 52--53 week fiscal year ending on the Sunday
closest to December 31. The years ended December 29, 1996, December 31, 1995 and
January 1, 1995 were each comprised of 52 weeks.

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 1996, 1995 and 1994:

                                             Fiscal Year Ended
                                    ------------------------------------
                                       1996        1995         1994
                                    ----------- ------------ -----------
Seagate Technology, Inc.                 52%         44%         40%
Western Digital Corporation              22%         12%         12%
Quantum Corporation/MKE                  18%         23%         23%
Hewlett-Packard Company                 -10%         15%         21%

In 1996,  Seagate  merged with Conner  Peripherals,  Inc. In  addition,  Quantum
ceased disk drive  production in Milpitas,  California and Penang,  Malaysia and
contracted  with  its  Japanese   manufacturing   partner,   Matsushita-Kotobuki
Electronics  Industries,  Ltd.  ("MKE"),  to manufacture all of its disk drives.
Percentages   for  1996,   1995  and  1994   represent  the  combined  sales  to
Seagate/Conner and Quantum/MKE.

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 95% 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,
certain polishing and texturing supplies and sputtering target materials.  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 could be adversely affected.


NOTE 4.  STOCKHOLDER'S 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.

NOTE 5.  STOCK OPTION PLANS AND STOCK PURCHASE PLAN

At December 29, 1996, the Company has stock-based  compensation plans, which are
described below. The Company has elected to follow  Accounting  Principles Board
Opinion  No.  25,  "Accounting  for  Stock  Issued  to  Employees"  and  related
Interpretations in accounting for its plans.  Accordingly,  no compensation cost
has been  recorded in the  financial  statements  for its stock option and stock
purchase plans. Had  compensation  cost for the stock-based  compensation  plans
been determined  consistent with Statement of Financial  Accounting Standard No.
123,  "Accounting  for Stock-Based  Compensation,"  the Company's net income and
earnings  per share would have been reduced to the pro forma  amounts  indicated
below:

FAS 123 is applicable only to options  granted  subsequent to December 31, 1994,
its pro forma effect will not be fully reflected until 1999.

Under the  Company's  stock  option plans  ("Plans"),  options to purchase up to
15,760,000 shares of Common Stock may be granted to key employees and directors.
The Plans provide for issuing both  incentive  stock  options and  non-qualified
stock options, both of which must be granted at 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  5,400,
17,000 and 11,000 shares of the Company's Common Stock were received in exchange
for option exercises in 1996, 1995 and 1994, respectively. At December 29, 1996,
approximately 2,191,000 options were available for grant and 7,936,000 shares of
Common Stock were reserved for future issuance under these Plans.  Approximately
1,917,000 and 1,487,000, of the outstanding options were exercisable at December
29, 1996 and December 31, 1995, respectively.

For purposes of the pro forma disclosure, the fair value of each option grant is
estimated on the date of grant using the Black-Scholes option pricing model with
the  following  assumptions  used for  grants  in 1996 and  1995,  respectively:
risk-free  interest rates of 6.1% and 6.4%;  volatility  factors of the expected
market  price  of  the  Company's  Common  Stock  of  60.0%  and  59.3%;  and  a
weighted-average expected life of the options of 5.9 and 6.2 years. There was no
dividend  yield  included  in  the  calculation  as the  Company  does  not  pay
dividends.  The  weighted-average  fair value of options granted during 1996 and
1995 is $12.88 and $8.58, respectively.

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 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  352,000,  431,000 and 469,000 in 1996, 1995
and 1994,  respectively.  At December 29, 1996  approximately  46,000  shares of
Common Stock were reserved for future issuance under this Plan.

For  purposes  of the pro forma  disclosure,  the fair  value of the  employees'
purchase  rights  has  been  estimated  using  the   Black-Scholes   model  with
assumptions  that,  except for an  expected  life of six  months  and  risk-free
interest  rates of 5.6% and 6.4% in 1996 and 1995,  were  consistent  with those
used for the Company's stock option plans described above. The  weighted-average
fair  value of those  purchase  rights  granted  in 1996 and 1995 was  $5.09 and
$6.36, respectively.


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.  In 1996, under the terms of the Company's bonus plans, a
percentage of consolidated annual operating profit, as defined in the respective
bonus  plans,  was  paid to  eligible  employees.  In  1995  and  1994,  various
percentages of an operating  unit's annual operating  profit,  as defined in the
respective  bonus plans,  was paid to eligible  employees.  The Company expensed
$9,078,000, $19,990,000 and $9,083,000 under these bonus and cash profit sharing
plans in 1996, 1995 and 1994, 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 each  employee's
contributions  to the  plans up to a maximum  amount.  The  Company  contributed
$5,573,000,  $6,653,000  and  $4,081,000  to the  plans in 1996,  1995 and 1994,
respectively.

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

As of December 29, 1996, a 60%-owned  subsidiary of the Company,  Dastek Holding
Company,  has a federal tax net operating  loss  carryforward  of  approximately
$100,000,000.  The Company has fully  reserved for the potential  future federal
tax  benefit of this net  operating  loss in the  deferred  tax asset  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
$257,000,  $1,189,000  and  $7,308,000  in  fiscal  years  1996,  1995 and 1994,
respectively.  The  $100,000,000  net  operating  loss  carryforward  expires at
various dates through 2010.

Komag USA (Malaysia) Sdn.  ("KMS"),  the Company's  wholly owned thin-film media
operation in Malaysia,  was granted its initial 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 initial 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
$21,800,000  ($0.41  per share)  and  $11,500,000  ($0.23 per share) in 1996 and
1995,  respectively.  Losses incurred prior to the  commencement of this initial
tax holiday,  approximately $6,237,000,  are available for carryforward to years
following the  expiration of the tax holiday.  The Company has also been granted
an additional ten-year tax holiday for new operations in Malaysia.  This new tax
holiday has not yet commenced at December 29, 1996.

The Company has  generated  $163,600,000  of earnings  for which no U.S. tax has
been  provided as of December 29, 1996.  These  earnings  are  considered  to be
permanently invested outside the United States.


NOTE 8.  TERM DEBT AND LINES OF CREDIT

The Company has  borrowed  $70,000,000  under its line of credit  facilities  at
December  29,  1996.  These  borrowings  bear  interest  at 5.9% to  6.4%,  with
interest-only  payments  due  quarterly.  Principal  payments  under the line of
credit agreements are due six and twelve months after the borrowing date but may
be extended for additional one- to  twelve-month  periods through the year 2000.
The Company  intends to extend the principal  repayment and has  classified  the
principal as long-term debt.  Interest rates in effect for the extension periods
will be based upon prevailing Eurodollar,  Federal Funds and/or LIBOR rates plus
0.375% to 0.55% at the time of principal extension.

The Company's  credit  facilities  total  $175,000,000  and are comprised of two
separate four-year  revolving line of credit agreements which expire in 2000 and
two separate four-year revolving line of credit agreements which expire in 1999.
These  agreements may be extended,  subject to bank  approvals,  annually for an
additional  year, thus  perpetuating  their multi-year  tenors.  At December 29,
1996, $105,000,000 was available under these unsecured credit facilities.

Subsequent  to year-end the Company  increased  its total credit  facilities  to
$265,000,000 through the addition of a new five-year $75,000,000 term loan and a
$15,000,000  increase in an existing credit  facility.  The term loan expires in
2002.

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.  At December 29, 1996, the Company is in compliance with
these debt covenants.


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  29, 1996 and December  31, 1995 due to the  relatively  short
period to maturity of the instruments. Fair value of long-term debt was based on
quoted market prices or pricing models using current market rates.  The carrying
value on the Consolidated  Balance Sheet approximates fair value at December 29,
1996.

NOTE 13.  PARTICIPATION IN HEADWAY TECHNOLOGIES, INC.

Headway Technologies,  Inc. ("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 12)  provided the
initial cash funding to Headway in exchange  for equity  interests.  The Company
and Asahi America  licensed to Headway MR technology  developed  through a prior
joint  venture and  contributed  certain  research and  production  equipment in
exchange  for equity.  As a result of these  transactions,  the  Company  held a
direct voting  interest in Headway of less than 20% and had no cost basis in its
investment in Headway.  Subsequent to year-end, the Company sold its interest in
Headway for $132,000.

AKCL  invested  in  Headway  in 1994  and  recorded  partial  writedowns  of its
investment  through 1995 based upon net losses  incurred at Headway.  During the
third quarter of 1996,  Headway's major customer,  HP,  announced the closure of
its disk drive manufacturing operations. Based upon anticipated future operating
losses at Headway  arising from the loss of HP's  business,  AKCL  wrote-off its
remaining Headway investment at the end of the third quarter of 1996. Subsequent
to year-end, AKCL sold its entire interest in Headway for $10,800,000 to a group
of new investors as part of a recapitalization.  AKCL recorded the proceeds from
this sale as a gain  ($5,300,000,  net of tax) in the first quarter of 1997. The
Company  will  reflect  its 50% share of this net gain in the first  quarter  of
1997.

         (b) Reports on Form 8-K.

         Not Applicable

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:

         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),  33-62543  (filed
September 12, 1995), and 333-06081 (filed June 14, 1996).

                        REPORT OF INDEPENDENT ACCOUNTANTS


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

     We have audited the accompanying consolidated balance sheets of Asahi Komag
Co.,  Ltd.  and  subsidiary  as of December  31, 1996 and 1995,  and the related
consolidated  statements of income, cash flows, and stockholder's equity for the
years then ended. We have also audited the statements of income, cash flows, and
stockholder's  equity of Asahi Komag Co.,  Ltd. for the year 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, 1996 and 1995,  and the  consolidated  results of its operations
and its cash flows for the years then ended,  and the results of operations  and
cash flows of Asahi  Komag Co.,  Ltd.  for the year 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,  1996 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.

respectively Landlord and Tenant.

     2.  Premises:  Landlord  hereby  leases to Tenant,  and  Tenant  hires from
Landlord those certain Premises with the appurtenances,  situated in the City of
San Jose,  County of Santa Clara,  State of  California,  and more  particularly
described as follows, to-wit:

A 12.6 acre parcel ("Parcel") on the north side of Automation Parkway, San Jose,
California,  including  all  appurtenances  and buildings now or during the Term
located thereon.  Pursuant to the terms of this Lease,  Landlord is obligated to
construct a single story building of approximately  188,303 rentable square feet
("Building"),  a parking  lot  consisting  of a minimum  of 544  parking  spaces
expandable to  approximately  656 spaces described as Building 10 on Exhibit "A"
attached  hereto.  Landlord  represents  and warrants  that  Landlord is the fee
simple owner of the Premises. Prior to the Commencement Date, Landlord shall use
its best  efforts  to  record a parcel  map to  subdivide  the  Parcel  into two
parcels,  one for the  Premises  and the  balance  for a second  building  to be
constructed  for Tenant  pursuant to that certain  lease  between the parties of
even date herewith.

     3. Use:  Tenant shall use the Premises only for the following  purposes and
shall not change the use of the Premises  without the prior  written  consent of
Landlord,  which consent shall not be unreasonably withheld or delayed:  Office,
research, development,  testing,  manufacturing,  ancillary warehouse, and other
legal uses.  Landlord makes no  representation or warranty that any specific use
of the Premises  desired by Tenant is permitted  pursuant to any Laws.  Landlord
represents  and warrants to Tenant that, as of the  Commencement  Date,  (i) the
Premises  are in  compliance  with all  municipal,  county,  state  and  federal
statutes,  laws,  ordinances,   including  zoning  ordinances,  and  regulations
governing and relating to the Building  Shell;  (ii) there shall exist no patent
or, to the best of Landlord's  knowledge,  latent  defect in the  Premises;  and

<PAGE>

     4. Term and Rental: The term ("Lease Term") shall be for one hundred twenty
(120)  months,  commencing  on the date on which the  Building  Shell and Tenant
Improvements  are  Substantially  Complete  as  defined  in  Article  7.H  below

("Expiration  Date"). In addition to all other sums payable by Tenant under this
Lease, Tenant shall pay as base monthly rent ("Base Monthly Rent") below for the
Premises in an amount determined  pursuant to Exhibit "B" attached hereto.  Base
Monthly Rent shall  increase at the end of the  forty-second  and eighty  fourth
month of the Lease Term by the product of the Base  Monthly Rent payable for the
preceding month and one and 147/1000 (1.147). The parties agree to enter into an
amendment to this Lease  setting forth the exact amount of the Base Monthly Rent
payable during the Lease Term within fourteen (14) days following  determination
by Landlord.

Base Monthly Rent shall be due on or before the first day of each calendar month
during Lease Term.  All sums payable by Tenant under this Lease shall be paid in
lawful money of the United States of America,  without offset or deduction,  and
shall be paid to Landlord at the address specified in Article 1 of this Lease or
at such place or places as may be designated from time to time by Landlord. Base
Monthly  Rent for any  period  less than a  calendar  month  shall be a pro rata
portion of the monthly installment.

     A.  Adjustment for Variance in Building  Square  Footage:  In the event the
square  footage of the Building is other than 188,303  determined by measurement
after completion of construction, within thirty (30) days after the Commencement
Date,  Landlord and Tenant shall execute an amendment to the Lease setting forth
the actual  rentable  square feet of the Building,  which  calculation  shall be
consistent  with the BOMA standard for  Industrial  Buildings  (i.e.  outside of
outside wall to outside of outside wall without deduction).

     5. Security Deposit: None required.

     6. Late Charges:  Tenant hereby acknowledges that late payment by Tenant to
Landlord of Base Monthly Rent and other sums due hereunder  will cause  Landlord
to incur costs not contemplated by this Lease, the exact amount of which will be
extremely  difficult to ascertain.  Such costs include,  but are not limited to,
administrative,  processing,  accounting charges, and late charges, which may be
imposed on Landlord by the terms of any contract,  revolving credit, mortgage or
trust deed  covering  the  Premises.  Accordingly,  if any  installment  of Base
Monthly  Rent or any other sum due from Tenant shall not be received by Landlord
or Landlord's  designee  within ten (10) days after Tenant's  receipt of written
notice  from  Landlord  that such  amount  is  delinquent,  Tenant  shall pay to
Landlord a late charge equal to five (5%)  percent of such overdue  amount which
late charge  shall be due and  payable  with the payment  then  delinquent.  The
parties  hereby  agree that such late charge  represents  a fair and  reasonable
estimate of the costs  Landlord  will incur by

                                     Page 2

reason of late  payment by Tenant.  Acceptance  of such late  charge by Landlord
shall in no event  constitute a waiver of Tenant's  default with respect to such
overdue amount, nor prevent Landlord from exercising any of the other rights and
remedies granted hereunder.

construction  defects,  or (iii) any failure to properly  construct the Building
Shell or Tenant  Improvements  in accordance  with the approved  Shell Plans and

this  Lease a "Broad  Form"  liability  insurance  policy in the amount of Three
Million  Dollars  ($3,000,000.00),  insuring all of Landlord's  activities  with

     8.  Acceptance of Possession  and Covenants to Surrender:  Tenant agrees on
Expiration  Date, or on the sooner  termination of this Lease,  to surrender the
Premises to Landlord in good  condition  and repair,  reasonable  wear and tear,

ascertain  from  Landlord  at the time  Tenant  desires  to make any  Alteration
(including  Permitted  Alterations),  whether  Landlord  desires  to  have  such
Alteration  removed at the  Expiration  Date or to cause Tenant to surrender the
Alteration to Landlord. If Landlord so notifies Tenant in writing within fifteen
(15) days after  Tenant's  notice to Landlord  that Tenant  intends to alter the
Building,  then Tenant shall remove such Alteration,  as Landlord may require in
such written notice,  and shall repair and restore said Building or such part or
parts thereof before the Expiration  Date at Tenant's sole cost and expense.  If
Landlord has not provided  Tenant with such written  notice  within said fifteen
(15) day period,  then Tenant shall have no obligation to remove such Alteration
from the Premises upon the Expiration Date or earlier termination of this Lease.

on any portion of the Premises outside of the Building proper without Landlord's
prior approval, which approval shall not be unreasonably withheld.

     10.  Alterations  and Additions:  Except for those  improvements  installed

remove any trade fixtures,  furniture,  or process  equipment paid for by Tenant
from the Premises at the  expiration  of the Lease,  which items shall  include,
without  limitation,  the items set forth in  Exhibit  "F"  attached  hereto and
incorporated herein by this reference.

              Notwithstanding  the  foregoing,  Tenant  shall  have  the  right,
without the prior  written  consent of Landlord,  to make  certain  alterations,
additions or improvements (the "Permitted  Alterations") which (i) do not affect
the Building  systems or  structural  components  of the Building and (ii) which
cost less,  on an individual  basis,  than One Hundred  Fifty  Thousand  Dollars
($150,000),  provided that each such Permitted Alteration is otherwise performed
in accordance with the terms of this Section 10.  Ownership of any  Alterations,
Permitted  Alterations or Tenant Improvements paid for by Tenant shall remain in
Tenant  throughout  the Term of this Lease,  and Tenant shall be entitled to the
benefit of any  depreciation or other tax benefits arising  therefrom,  provided
that Landlord shall, upon the Expiration Date or earlier termination of the Term

damage  resulting  from  normal  wear and tear,  casualty  or other acts of God,
Landlord,  Landlord's  agents,  employees,  contractors  or invitees  ("Landlord

contractor  who is  reasonably  satisfactory  to both  Tenant and  Landlord,  at
Tenant's  sole cost, to inspect the roof membrane at least every six (6) months,
with the first inspection due the sixth (6th) month after the Commencement Date,
and (ii) Tenant  performs,  at Tenant's sole cost,  all  preventive  maintenance

trimming trees overhanging the roof membrane, applying coating materials to seal
roof penetrations,  repairing blisters, and other routine measures.  Tenant make
available for Landlord's  inspection such preventive  maintenance  contracts and

herein  shall  require   either   Landlord  or  Tenant  to  replace  any  Tenant
Improvements.

         B. Landlord's  Obligations:  Landlord at its sole cost and expense, and
without  reimbursement of all or any such costs from Tenant,  shall (i) maintain

repairs or  replacements  that are required of Landlord  under the terms of this
Lease and Landlord  shall proceed  forthwith to effect the same with  reasonable
diligence.  In the event of an emergency  Tenant shall be empowered to undertake
immediate  repairs  of such  nature as would be  Landlord's  responsibility  and

<PAGE>

be used,  for any purpose other than that for which the said Premises are hereby
leased;  and no use shall be made or permitted to be made of the said  Premises,
nor acts done,  which will cause a cancellation of any insurance policy covering
said Building,  or any part thereof, nor shall Tenant sell or permit to be kept,
used or sold, in or about said Premises,  any article which may be prohibited by
the standard  form of fire  insurance  policies.  Tenant  shall  (subject to the

Tenant's  specific  use), at its sole cost and expense,  comply with any and all
reasonable   requirements,   pertaining  to  said  Premises,  of  any  insurance
organization  or company,  necessary for the  maintenance of reasonable fire and
public liability insurance, covering said Premises and appurtenances.

         B. Landlord's Liability Insurance.  Landlord shall procure and maintain
during  the Term of this  Lease a policy  of (i)  commercial  general  liability

general  aggregate  insurance in an amount of not less than Five Million Dollars
($5,000,000.00).  The policy  shall  provide  coverage  for blanket  contractual
liability  (except for the negligence or willful  misconduct of the  non-insured
party) premises and personal injury  coverage.  Landlord shall furnish to Tenant
prior to the Commencement  Date, and thereafter within thirty (30) days prior to
the  expiration of each such policy,  a certificate  of insurance  issued by the

Tenant.  Tenant agrees to pay to the Landlord as additional rent, on demand, the
full cost of said insurance as evidenced by insurance  billings to the Landlord,
and in the event of damage covered by said insurance  which does not result in a
termination  of this  Lease,  the amount of any  deductible  under such  policy,
provided such deductible is not greater than $20,000.00. Payment shall be due to
Landlord within ten (10) days after written invoice to Tenant.  It is understood
and agreed  that  Tenant's  obligation  under this  Article  will be prorated to
reflect the commencement and termination dates of this Lease.

written  notice  to  Landlord;  and (v)  Tenant  has  delivered  to  Landlord  a
certificate  of insurance and additional  insured  endorsement  evidencing  such
policy is in effect.

         E.  Tenant's  Insurance:  In  addition,  Tenant  agrees to  insure  its
personal  property,  the  

                                    Page 11
<PAGE>

Tenant Improvements, any Alterations not owned by Landlord pursuant to the terms
of Article 10 and to obtain  worker's  compensation  and  public  liability  and
property  damage  insurance  for  occurrences  within the Premises with combined
limits for bodily injury and property damage of not less than  $1,000,000.00 per
occurrence and a general aggregate limit of not less than $5,000,000.00.  Tenant
shall name  Landlord  and  Landlord's  lender as an  additional  insured,  shall
deliver a copy of the policies and renewal  certificates  to Landlord.  All such
policies shall provide for thirty (30) days' prior written notice to Landlord of
any cancellation, termination, or reduction in coverage.

         D. Waiver: Landlord and Tenant hereby waive any and all rights each may
have  against  the  other on  account  of any loss or damage  occasioned  to the
Landlord or the Tenant as the case may be, or to the  Premises or its  contents,
and which may arise from any risk covered by their respective insurance policies
(or which would have been covered had such insurance policies been maintained in
accordance with this Lease),  as set forth above.  The parties shall obtain from
their respective  insurance companies a waiver of any right of subrogation which
said insurance  company may have against the Landlord or the Tenant, as the case
may be.

         E. General:  Insurance required hereunder shall be written by companies
licensed to do business in the state in which the  Premises are located and have
a General  Policyholder's rating of at least A8 (or such higher rating as may be
required  by a lender  having a lien on the  Property)  as set forth in the most
current issue of Best's Insurance  Guide. All insurance shall expressly  provide
that such  policies  shall not be cancelable or subject to reduction of coverage
or  otherwise  be subject to  modification  except  after thirty (30) days prior
written notice to any other party named as additional insureds.

     13. Taxes:  Tenant shall be liable for, and shall pay prior to delinquency,
all taxes and assessments levied against personal property and trade or business
fixtures,  and agrees to pay, as  additional  rental,  all real estate taxes and
assessment  installments  (special or general) or other  impositions  or charges
which may be levied on the  Premises,  upon the  occupancy  of the  Premises and
including any substitute or additional  charges which may be imposed during,  or
applicable to the Lease Term  including  real estate tax increases due to a sale
or other  transfer  of the  Premises,  as they appear on the City and County tax
bills during the Lease Term, and as they become due. It is understood and agreed
that  Tenant's  obligation  under this  Article  will be prorated to reflect the
Commencement and Expiration  Dates. If, at any time during the Lease Term a tax,
excise on rents,  business license tax, or any other tax, however described,  is
levied or assessed against Landlord,  as a substitute or addition in whole or in
part for taxes  assessed or imposed on land or  Buildings,  Tenant shall pay and
discharge  his pro rata share of such tax or excise on rents or other tax before
it becomes  delinquent.  In the event that a tax is placed,  levied, or assessed
against  Landlord and the taxing  authority  takes the position  that the Tenant
cannot  pay and  discharge  his pro  rata  share of such  tax on  behalf  of the
Landlord,  then at the sole election of the Landlord,  the Landlord may increase
the rental  charged  hereunder  by the exact amount of such tax and Tenant shall
pay such increase as

                                    Page 12
<PAGE>

additional  rent  hereunder.  Landlord  hereby  grants  to  Tenant  the right to
contest, on behalf and in the name of Landlord,  all taxes and assessments which
are imposed upon the Premises;  Landlord  agrees to cooperate  fully with Tenant
and to execute all documents  requested by Tenant,  in connection  with any such
contest.  If by virtue of any  application  or  proceeding  brought by  Landlord
results a reduction in the assessed value of the Building during the Lease Term,
Tenant agrees to reimburse  Landlord its  reasonable,  actual third party out of
pocket  costs  incurred by  Landlord  in  connection  with such  application  or
proceeding.

         Notwithstanding the foregoing,  the following shall not constitute real
estate taxes for the purposes of this Lease, and nothing  contained herein shall
be deemed to require Tenant to pay any of the following:  (i) any state,  local,
federal,  personal or  corporate  income tax measured by the income of Landlord;
(ii) any  estate or  inheritance  taxes;  (iii)  any  franchise,  succession  or
transfer  taxes;  (iv) interest on taxes or penalties  resulting from Landlord's
failure  to pay  taxes,  except to the extent  such  failure is due to  Tenant's
failure to pay such taxes to Landlord  when provided  under this Lease;  (v) any
assessments for public improvements or any taxes initiated by Landlord which are
essentially payments to a governmental agency for the right to make improvements
to the Building or surrounding  area, to the extent such  assessments are not in
effect as of the Execution Date and have not received the prior written  consent
of Tenant;  and (vi) any environmental tax, surcharge or other fee affecting the
Premises due to Landlord's  activities with respect to Hazardous  Materials,  as
opposed to general, areawide taxes or surcharges with respect to the remediation
or testing for Hazardous  Materials.  If any assessments  affecting the Premises
are payable in  installments  and Landlord  should  prepay such  assessments  in
advance of the date such  installments  would become due, Tenant shall be solely
responsible for the portion of such assessment that would have normally come due
as an installment, unless consented to by Tenant in writing.

         Notwithstanding  anything  to the  contrary  contained  in this  Lease,
Landlord  shall pay,  and  Tenant  shall have no  responsibility  for,  any real
property taxes  resulting from any change in ownership,  sale, or other transfer
of the  Premises or Building  during the initial Term of the Lease to the extent
that such amount reflects an assessed valuation of the Premises in excess of one
hundred  fifty  percent  (150%)  of  the  "Commencement   Date  Valuation."  The
"Commencement  Date Valuation" shall mean the assessed valuation of the Premises
(as  improved  with the  Building)  as  determined  by the  Santa  Clara  County
Assessor,  as of the first date after the Commencement Date that the Santa Clara
County Assessor  reassesses the Premises based on the completion of construction
of the Building and Tenant Improvements.

     14.  Utilities:  Tenant  shall pay  directly to the  providing  utility all
water, gas, heat, light,  power,  telephone and other utilities  supplied to the
Premises.  Except  for  any  damages  resulting  from  the  negligence,  willful
misconduct,  or breach of contract by Landlord,  or its agents,  or  contractors
Landlord  shall not be  liable  for a loss of or  injury  to  property,  however
occurring,  through or in connection with or incidental to furnishing or failure
to furnish any  utilities  to the 

                                    Page 13
<PAGE>

Premises  and Tenant  shall not be entitled to  abatement  or  reduction  of any
portion of the Base  Monthly  Rent so long as any failure to provide and furnish
the utilities to the Premises is due to a cause beyond the Landlord's reasonable
control, and is not the result of the negligence,  willful misconduct, or breach
of contract by Landlord, or its agents, or contractors.

              In the event of any  interruption  in  utilities or services to be
provided to the Premises,  Tenant's rights and remedies shall be as follows: (i)
if such  interruption is due to a failure of Tenant to pay the providing utility
when due, Base Rent due hereunder shall not be abated and Landlord shall have no
liability to Tenant  whatsoever as a result of such  interruption;  (ii) if such
interruption is due to the actions of Landlord or Landlord's  Parties,  the Base
Rent  hereunder  shall be  equitably  abated  as of the time  such  interruption
commenced and Landlord  shall be liable to Tenant for loss or injury to property
and Tenant's business as a result thereof;  (iii) if such interruption is due to
the failure of the  providing  utility to provide such utility or service to the
Premises and such  interruption  continues for more than ninety (90)  continuous
days,  then  Tenant  shall be entitled  to  terminate  this Lease by delivery of
written notice to Landlord within five (5) days following the expiration of such
ninety  (90) day  period;  and (iv) if such  interruption  is due to an event of
damage or destruction, the rights of the parties hereunder shall be as described
in Section 28 below.

     15. This paragraph intentionally left blank

     16. Free From Liens:  Except for obligations  arising from the construction
of the Building Shell , Tenant Improvements,  and parking lot, Tenant shall keep
the Premises  free from any liens arising out of any work  performed,  materials
furnished,  or obligations incurred by Tenant.  Landlord shall keep the Premises
free from any liens arising out of any work performed,  materials furnished,  or
obligations incurred in connection with the Building Shell, Tenant Improvements,
or parking  lot. In the event  Tenant  fails to  discharge or bond over any such
lien within  thirty  (30) days after  receiving  notice of the filing,  Landlord
shall be entitled to discharge  such lien at Tenant's  expense and all resulting
costs incurred by Landlord,  including  reasonable  attorney's fees shall be due
from Tenant as additional rent.

     17.  Compliance With  Governmental  Regulations:  Tenant shall, at its sole
cost and expense,  comply with all of the  requirements of all Municipal,  State
and Federal  authorities now in force, or which may hereafter be in force, which
are imposed as a result of Tenant's particular and specific use of the Premises,
and shall faithfully observe in the use of the Premises all Municipal ordinances
and State and Federal  statutes now in force or which may hereafter be in force.
The judgment of any court of competent jurisdiction,  or the admission of Tenant
in any action or proceeding against Tenant,  whether Landlord be a party thereto
or not, that Tenant has violated any such ordinance or statute in the use of the
Premises,  shall be conclusive of that fact as between  Landlord and Tenant.  In
the event an  Alteration  is required to the  Building  Shell by any law,  rule,

                                    Page 14
<PAGE>

ordinance  or decision not in effect as of the  Commencement  Date of this Lease
which is not imposed as a result of Tenant's  particular and specific use of the
Premises  (whether pursuant to Article 12 or this Article 17), Tenant shall only
be required  to pay that  portion of the cost equal to the product of such total
cost  multiplied  by a fraction,  the numerator of which is the number of months
remaining  in the Lease Term,  the  denominator  of which is the useful life (in
months) of the Alteration.

     18. Toxic Waste and Environmental Damage: 

         A.  Landlord's  Responsibility:  Landlord  represents  and  warrants to
Tenant that,  except as disclosed in the attached  environmental  studies  dated
June 18, 1990,  July 2, 1990,  July 25, 1994,  and the  Burrowing Owl study from
H.T. Harvey & Associates,  to the best of Landlord's knowledge, the Premises and
the Building,  as of the Commencement Date, do not contain any chemicals,  toxic
or hazardous  gaseous,  liquid or solid  materials or waste,  including  without
limitation,  material  or  substance  having  characteristics  of  ignitability,
corrosivity,  reactivity,  or  extraction  procedure  toxicity or  substances or
materials which are listed on any of the Environmental  Protection Agency's list
of hazardous  wastes or which are  identified  in Section 66680 through 66685 of
Title 22 of the  California  Administrative  Code, 42 U.S.C.  Sections  9601, et
seq., 49 U.S.C.  Sections  1801, et seq., 42 U.S.C.  Sections  6901, et seq., or
California Health and Safety Code Section 25117, as the same may be amended from
time to time ("Hazardous Materials").  Landlord shall indemnify, protect, defend
and hold  Tenant  harmless  from and  against all  liability,  cost,  damage and
expense (including, without limitation attorneys' fees) arising from either: (i)
the failure of the  representation  and warranty  contained  in the  immediately
preceding  sentence;  (ii) the presence of any Hazardous  Materials or Burrowing
Owls on or about the Premises on or prior to the Commencement Date; or (iii) the
presence,  release, storage or use of Hazardous Materials on the Premises during
the Term by any party other than Tenant, Tenant's agents, employees, contractors
or invitees ("Tenant's Parties").

         B. Tenant's Responsibility: Landlord hereby approves Tenant's use on or
about the  Premises of Hazardous  Materials  used by Tenant in  connection  with
Tenant's business. Tenant represents and warrants that Tenant will (i) adhere to
all reporting and inspection  requirements imposed by Federal,  State, County or
Municipal laws, ordinances or regulations and will make available for inspection
by Landlord a copy of any such  reports or agency  inspections,  (ii) obtain and
make  available  for  inspection  by Landlord  copies of all  necessary  permits
required for the use and handling  Hazardous  Materials on the  Premises,  (iii)
enforce  Hazardous  Materials  handling and disposal  practices  consistent with
industry  standards,  (iv)  surrender  the  Premises  free  from  any  Hazardous
Materials  arising  from  Tenant's  bringing,  using,  permitting,   generating,
emitting  or  disposing  of  Hazardous  Materials,  and (v)  properly  close the
facility   with  regard  to  Hazardous   Materials   including  the  removal  or
decontamination  of any  process  piping,  mechanical  ducting,  storage  tanks,
containers,  or trenches  which have come  become  contaminated  with  Hazardous
Materials and obtain a closure certificate from the local  administering  agency
prior to the Expiration

                                    Page 15
<PAGE>

Date to the extent required by Law.

         C.  Tenant's  Indemnity  Regarding  Hazardous  Materials:  Tenant shall
comply,  at its sole cost,  with all laws pertaining to, and shall indemnify and
hold Landlord harmless from any claims, liabilities,  costs or expenses incurred
or  suffered  by  Landlord  arising  from  such  bringing,   using,  permitting,
generating,  emitting or  disposing  of  Hazardous  Materials on the Premises by
Tenant  or  Tenant's  Parties.   Tenant's   indemnification  and  hold  harmless
obligations  include,  without  limitation,  (i)  claims,  liability,  costs  or
expenses  resulting  from or  based  upon  administrative,  judicial  (civil  or
criminal) or other action, legal or equitable,  brought by any private or public
person  under  common  law or under the  Comprehensive  Environmental  Response,
Compensation and Liability Act of 1980 ("CERCLA"), the Resource Conservation and
Recovery Act of 1980 ("RCRA") or any other Federal,  State,  County or Municipal
law,  ordinance  or  regulation,  (ii)  claims,  liabilities,  costs or expenses
pertaining to the identification,  monitoring,  cleanup, containment, or removal
of Hazardous Materials from soils, riverbeds or aquifers including the provision
of an alternative  public drinking water source,  and (iii) all reasonable costs
of defending such claims.

         D. Actual  Release by Tenant:  Tenant  agrees to notify  Landlord  upon
learning  of any  lawsuits  which  relate  to,  or  orders  which  relate to the
remedying  of, the actual  release by Tenant or  Tenant's  Parties of  Hazardous
Materials on or into the soils or groundwater  at or under the Premises.  Tenant
shall also provide to Landlord all notices required by Section 25359.7(b) of the
Health  and Safety  Code and all other  notices  required  by law to be given to
Landlord in connection with Hazardous Materials. Without limiting the foregoing,
Tenant  shall also deliver to Landlord,  within  twenty (20) days after  receipt
thereof,  any written notices from any  governmental  agency alleging a material
violation of, or material  failure to comply with,  any federal,  state or local
laws,  regulations,  ordinances or orders,  the violation of which of failure to
comply with,  poses a  foreseeable  and material  risk of  contamination  of the
groundwater or injury to humans (other than injury solely to Tenant,  its agents
and employees within the Improvements on the Property).

         In the event of any release on or into the Premises or into the soil or
groundwater under the Premises of any Hazardous Materials used, treated,  stored
or disposed of by Tenant, Tenant agrees to comply, at its sole cost and expense,
with all laws, regulations, ordinances and orders of any federal, state or local
agency relating to the monitoring or remediation of such Hazardous Materials. In
the event of any such release of Hazardous Materials,  Tenant agrees to meet and
confer with  Landlord  and its Lender to attempt to  eliminate  and mitigate any
financial  exposure to such  Lender and  resultant  exposure  to Landlord  under
California  Code of Civil  Procedure  section 736(b) as a result of such release
and promptly to take  reasonable  monitoring,  cleanup and remedial steps given,
inter alia,  the  historical  uses to which the Property has and continues to be
used,  the risks to  public  health  posed by the  release,  the then  available
technology and the costs of remediation, cleanup and monitoring, consistent with
acceptable  customary  practices for the type and severity of such contamination
and all applicable  laws.  Nothing in the preceding  sentence  shall  eliminate,

                                    Page 16
<PAGE>

modify or reduce the  obligation  of Tenant under  Article 18.B of this Lease to
indemnify  and hold  Landlord  harmless  from any claims  liabilities,  costs or
expenses  incurred or  suffered by Landlord as provided in Article  18.B of this
Lease.   Tenant  shall  provide  Landlord  prompt  written  notice  of  Tenant's
monitoring, cleanup and remedial steps. Tenant shall have the right, at Tenant's
expense and in Tenant's  name, to contest or object in good faith to any alleged
violation  by Tenant of any  applicable  law  relating  to the use of  Hazardous
Materials  by  appropriate  legal  proceedings  which  are  not  prejudicial  to
Landlord's   rights  if  (i)  Tenant  shall  have   demonstrated  to  Landlord's
satisfaction that such legal proceedings shall  conclusively  operate to prevent
enforcement prior to final  determination of any such proceedings.  In the event
that, by  non-performance of any such items, the Premises is subject to imminent
loss or  forfeiture,  Tenant shall perform any such act required by the relevant
governmental authority.

         In the absence of an order of any federal,  state or local governmental
or  quasi-governmental  agency  relating to the  cleanup,  remediation  or other
response action required by applicable law, any dispute arising between Landlord
and Tenant  concerning  Tenant's  obligation to Landlord under this Article 18.D
concerning  the Level,  method,  and manner of cleanup,  remediation or response
action required in connection  with such a release of Hazardous  Materials shall
be resolved by  mediation  and/or  arbitration  pursuant  to the  provisions  of
Article 45 of this Lease.

         E.  Environmental  Monitoring:  Landlord  and its agents shall have the
right,  at Landlord's  sole cost and expense,  (unless Tenant is in violation of
this Article 18 in which event such monitoring shall be at Tenant's  expense) to
inspect,  investigate,  sample and/or  monitor the Premises,  including any air,
soil,  water,  groundwater  or other  sampling  or any other  testing,  digging,
drilling or analysis to determine  whether Tenant is complying with the terms of
this Article 18. If Landlord discovers that Tenant is not in compliance with the
terms of this  Article  18, any such  reasonable  costs  incurred  by  Landlord,
including attorneys' and consultants' fees shall be due and payable by Tenant to
Landlord within thirty (30) days following Landlord's written demand therefore.

     19.  Indemnity:  As a material part of the  consideration to be rendered to
Landlord, Tenant hereby waives all claims against Landlord for damages to goods,
wares and  merchandise,  and all other personal  property in, upon or about said
Premises and for injuries to persons in or about said  Premises,  from any cause
except to the extent due to the negligence or willful  misconduct of Landlord or
Landlord's  Parties to the fullest  extent  permitted  by law,  and Tenant shall
indemnify and hold Landlord exempt and harmless from any damage or injury to any
person,  or to the goods,  wares and merchandise and all other personal property
of any person, arising from the use of the Premises, Building, and/or Project by
Tenant, its employees,  contractors,  agents and invitees or from the failure of
Tenant to keep the Premises in good  condition and repair,  as herein  provided,
except to the extent due to the negligence or willful  misconduct of Landlord or
Landlord's  Parties.  Further,  in the  event  Landlord  is  made  party  to any
litigation due to the acts or omission of Tenant,  its 

                                    Page 17
<PAGE>

employees,  contractors,  agents and  invitees,  Tenant will  indemnify and hold
Landlord  harmless from any such claim or liability  including  Landlord's costs
and expenses and reasonable attorney's fees incurred in defending such claims.

         Landlord  shall  defend,  indemnify  by counsel  acceptable  to Tenant,
protect Tenant, its officers, employees and agents harmless from and against any
liabilities,  loss,  cost,  damage,  injury  or  expense  (including  reasonable
attorneys'  fees and court  costs)  arising  out of or  related  to the  willful
misconduct or negligence of Landlord or Landlord's Parties.

     20. Advertisements and Signs: Tenant will not place or permit to be placed,
in, upon or about the exterior of the Building any signs which are prohibited by
the city or other governing  authority.  The Tenant will not place, or permit to
be placed,  upon the  exterior of the  Building,  any signs,  advertisements  or
notices  without the written consent of the Landlord as to type,  size,  design,
lettering,  coloring and  location,  and such  consent will not be  unreasonably
withheld.  Any sign so placed on the exterior of the Building shall be so placed
upon the  understanding  and  agreement  that  Tenant  will  remove  same at the
termination of the tenancy herein created and repair any damage or injury to the
exterior of the Building  caused  thereby,  and if not so removed by Tenant then
Landlord may have same so removed at Tenant's expense.

     21.  Attorney's  Fees:  In  case a suit  or  alternative  form  of  dispute
resolution  should  be  brought  for the  possession  of the  Premises,  for the
recovery  of any sum due  hereunder,  or  because  of the  breach  of any  other
covenant herein, the losing party shall pay to the prevailing party a reasonable
attorney's fee including the expense of expert witnesses,  depositions and court
testimony  as part of its costs  which  shall be deemed to have  accrued  on the
commencement of such action. In addition, the prevailing party shall be entitled
to recover all costs and expenses including reasonable  attorney's fees incurred
by the  prevailing  party in enforcing  any judgment or award  against the other
party. The foregoing provision relating to post-judgment costs is intended to be
severable from all other provisions of this Lease.

     22.  Tenant's  Default:  The  occurrence  of  any of  the  following  shall
constitute a material default and breach of this Lease by Tenant: a) Any failure
by Tenant to pay the rental or to make any other payment  required to be made by
Tenant hereunder,  where such failure continues for ten (10) days after Tenant's
receipt of written notice thereof by Landlord to Tenant;  b) A failure by Tenant
to observe  and  perform  any other  provision  of this Lease to be  observed or
performed  by Tenant,  where such failure  continues  for thirty (30) days after
Tenant's receipt of written notice thereof by Landlord;  provided, however, that
if the nature of such default is such that the same cannot  reasonably  be cured
within such thirty (30) day period  Tenant  shall not be deemed to be in default
if Tenant shall within such period commence such cure and thereafter  diligently
prosecute  the same to  completion;  c) The  making  by  Tenant  of any  general
assignment  for the benefit of creditors;  the filing by or against  Tenant of a
petition to have Tenant adjudged a bankrupt or of a 

                                    Page 18
<PAGE>

petition for  reorganization or arrangement under any law relating to bankruptcy
(unless,  in the case of a petition filed against Tenant,  the same is dismissed
after the filing);  the  appointment of a trustee or receiver to take possession
of  substantially  all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within ninety
(90)  days;  or  the  attachment,   execution  or  other  judicial   seizure  of
substantially  all of  Tenant's  assets  located at the  Premises or of Tenant's
interest in this Lease,  where such seizure is not discharged within ninety (90)
days.  The  notice  requirements  set  forth  herein  are in  lieu of and not in
addition to the notices  required by California Code of Civil Procedure  Section
1161. Any notice given by Landlord to Tenant  pursuant to California  Civil Code
1161 with  respect  to any  failure by Tenant to pay rent under this Lease on or
before the date the rent is due shall  provide  Tenant  with a period of no less
than ten (10) days to pay such rent or quit.

         A.  Remedies:  In the  event of any such  default  by  Tenant,  then in
addition  to any other  remedies  available  to  Landlord  at law or in  equity,
Landlord shall have the immediate  option to terminate this Lease and all rights
of Tenant hereunder by giving written notice of such intention to terminate.  In
the event that Landlord shall elect to so terminate this Lease then Landlord may
recover from Tenant:  a) the worth at the time of award of any unpaid rent which
had been earned at the time of such  termination;  plus b) the worth at the time
of award of the amount by which the unpaid  rent  which  would have been  earned
after termination until the time of award exceeds the amount of such rental loss
for the same period that Tenant proves could have been reasonably avoided;  plus
c) the worth at the time of award of the amount by which the unpaid rent for the
balance  of the Lease Term  after the time of award  exceeds  the amount of such
rental loss that Tenant  proves could be reasonably  avoided;  plus d) any other
amount necessary to compensate Landlord for all the detriment proximately caused
by Tenant's failure to perform its obligations  under this Lease or which in the
ordinary  course of  things  would be  likely  to  result  therefrom,  and e) at
Landlord's  election,  such  other  amounts  in  addition  to or in  lieu of the
foregoing as may be permitted  from time to time by applicable  California  law.
The term "rent",  as used herein,  shall be deemed to be and to mean the minimum
monthly installments of Base Monthly Rent and all other sums required to be paid
by Tenant pursuant to the terms of this Lease,  all other such sums being deemed
to be additional rent due hereunder. As used in (a) and (b) above, the "worth at
the time of award" is to be  computed  by  allowing  interest at the rate of the
discount  rate of the  Federal  Reserve  Bank of San  Francisco  plus  five (5%)
percent per annum. As used in (c) above,  the "worth at the time of award" is to
be  computed by  discounting  such  amount at the  discount  rate of the Federal
Reserve Bank of San Francisco at the time of award plus one (1%) percent.

         B.  Right to  Re-enter:  In the event of any such  default  by  Tenant,
Landlord shall also have the right,  with or without  terminating this Lease, to
re-enter the Premises  and remove all persons and  property  from the  Premises;
such  property  may be removed and stored in a public  warehouse or elsewhere at
the cost of and for the  account of Tenant and  disposed  of by  Landlord in any
manner permitted by law.

                                    Page 19
<PAGE>

         C.  Abandonment:  In the event of the  vacation or  abandonment  of the
Premises  by Tenant or in the event that  Landlord  shall  elect to  re-enter as
provided in Article 22.B above or shall take possession of the Premises pursuant
to legal  proceeding or pursuant to any notice provided by law, then if Landlord
does not elect to terminate  this Lease as provided in Article 22.A above,  then
the provisions of California  Civil Code Section 1951.4,  (Landlord may continue
the lease in effect after Tenant's breach and abandonment and recover rent as it
becomes  due,  if  Tenant  has a right to sublet  and  assign,  subject  only to
reasonable  limitations) as amended from time to time,  shall apply and Landlord
may from time to time, without terminating this Lease, either recover all rental
as it becomes  due or relet the  Premises  or any part  thereof for such term or
terms and at such rental or rentals and upon such other terms and  conditions as
Landlord  in its sole  discretion  may  deem  advisable  with the  right to make
alterations and repairs to the Premises.  In the event that Landlord shall elect
to so relet,  then rentals  received by Landlord  from such  reletting  shall be
applied:  first, to the payment of any indebtedness other than Base Monthly Rent
due  hereunder  from Tenant to Landlord;  second,  to the payment of any cost of
such reletting; third, to the payment of the cost of any alterations and repairs
to the  Premises;  fourth,  to the payment of Base  Monthly  Rent due and unpaid
hereunder;  and the  residue,  if any,  shall be held by Landlord and applied in
payment of future  Base  Monthly  Rent as the same may  become  due and  payable
hereunder.  Landlord shall have no obligation to relet the Premises  following a
default if Landlord  has other  available  space within the Building or Project.
Should that  portion of such rentals  received  from such  reletting  during any
month, which is applied by the payment of rent hereunder,  be less than the rent
payable  during  that  month by Tenant  hereunder,  then  Tenant  shall pay such
deficiency  to Landlord  immediately  upon demand  therefor  by  Landlord.  Such
deficiency  shall be  calculated  and paid  monthly.  Tenant  shall  also pay to
Landlord, as soon as ascertained, any costs and expenses incurred by Landlord in
such  reletting  or in making  such  alterations  and repairs not covered by the
rentals received from such reletting.

         D. No Termination:  No re-entry or taking possession of the Premises by
Landlord  pursuant to 22.B or 22.C of this  Article 22 shall be  construed as an
election to terminate  this Lease unless a written  notice of such  intention be
given to Tenant or unless  the  termination  thereof  be  decreed  by a court of
competent  jurisdiction.  Notwithstanding  any reletting without  termination by
Landlord  because of any default by Tenant,  Landlord may at any time after such
reletting elect to terminate this Lease for any such default.

     23.  Surrender of Lease:  The voluntary or other surrender of this Lease by
Tenant,  or a mutual  cancellation  thereof,  shall not  automatically  effect a
merger of the Lease with Landlord's  ownership of the Premises.  Instead, at the
option  of  Landlord,  Tenant's  surrender  may  terminate  all or any  existing
sublease or subtenancies,  or may operate as an assignment to Landlord of any or
all such subleases or subtenancies,  thereby  creating a direct  Landlord-Tenant
relationship between Landlord and any subtenants.

     24. Habitual Default: Deleted.

     25. Landlord's  Default:  In the event of Landlord's failure to perform any
of its  covenants or  agreements  under this Lease,  Tenant shall give  Landlord
written notice of such failure and shall give Landlord  thirty (30) days to cure
such failure; provided, however, that if the nature of such default is such that
the same cannot  reasonably be cured within such thirty (30) day period Landlord
shall not be deemed to be in  default  if  Landlord  shall  within  such  period
commence such cure and thereafter  diligently  prosecute the same to completion.
In  addition,  upon any such  failure by  Landlord,  Tenant shall give notice by
registered or certified mail or national overnight courier service to any person
or entity  with a  security  interest  in the  Premises  ("Mortgagee")  that has
provided Tenant with written notice (including such Mortgagee's  address) of its
interest in the Premises,  and shall  provide such  Mortgagee a period of thirty
(30) days  beyond  the cure  period  provided  Landlord  hereunder  to cure such
failure. Tenant shall not make any prepayment of rent more than one (1) month in
advance without the prior written  consent of such Mortgagee.  Tenant waives any
right under  California Civil Code Section 1950.7 or any other present or future
law to the  collection  of any  payment or deposit  from such  Mortgagee  or any
purchaser  at a  foreclosure  sale  of such  Mortgagee's  interest  unless  such
Mortgagee or such  purchaser  shall have actually  received (or have credited to
it) and not refunded the applicable payment or deposit.

     26. Notices:  All notices,  demands,  requests,  or consents required to be
given under this Lease shall be sent in writing by U.S.  certified mail,  return
receipt  requested,  national  overnight courier service or by personal delivery
addressed to the party to be notified at the address for such party specified in
Article 1 of this Lease,  or to such other place as the party to be notified may
from  time to time  designate  by at least  five (5) days  prior  notice  to the
notifying party.

     27.  Entry by  Landlord:  Upon 24 hours prior  notice,  Tenant shall permit
Landlord and his agents to enter into and upon said  Premises at all  reasonable
times  subject to any  security  regulations  of Tenant for the  purposes of (i)
inspecting  the same,  (ii)  maintaining  the  Premises,  (iii) making  repairs,
alterations or additions to the Premises,  (iv) erecting additional  building(s)
and  improvements  on the land where the Premises are  situated,  or on adjacent
land owned by Landlord,  or (v) performing any obligations of the Landlord under
the Lease including  remediation of hazardous  materials if determined to be the
responsibility  of  Landlord,  without any  abatement  or  reduction  of rent or
without any liability to Tenant for any loss of occupation or quiet enjoyment of
the Premises  thereby  occasioned.  Tenant shall permit  Landlord and Landlord's
Parties,  at any  time  within  one  hundred  eighty  (180)  days  prior  to the
Expiration  Date,  unless  Tenant  has  exercised  its option to extend the term
pursuant  to  Section  37.A (or at any time  during  the  Lease if  Tenant is in
default hereunder beyond the applicable cure period), to place upon the Premises
"For  Lease"  signs  and  exhibit  the  Premises  to  real  estate  brokers  and
prospective  tenants at  reasonable  hours.  Landlord  agrees that  Landlord and
Landlord's  Parties shall conduct all of their  activities under this 

                                    Page 21
<PAGE>

Section 27 in a manner which  minimizes the  interruption  to Tenant or Tenant's
activities on the Premises.

     28. Destruction of Premises: PREMISES

         A.  Destruction  by an  Insured  Casualty:  In the  event of a  partial
destruction  of the  Premises  by a casualty  for which  Landlord  has  received
insurance  proceeds  sufficient to repair the damage or  destruction  during the
Lease  Term from any  cause,  Landlord  shall  forthwith  repair the same to the
extent of such  proceeds,  provided  such repairs can be made within twelve (12)
months from the date of  destruction  as reasonably  determined by the architect
responsible for the  reconstruction  such  determination to be made within sixty
(60) days of the date of destruction,  and such partial  destruction shall in no
way  annul or void  this  Lease,  except  that  Tenant  shall be  entitled  to a
proportionate  reduction of Base Monthly Rent while such repairs are being made,
such proportionate  reduction to be based upon the extent to which the making of
such  repairs  shall  interfere  with the  business  carried on by Tenant in the
Premises.  For  purposes  of  this  Article  "partial  destruction"  shall  mean
destruction of no greater than one-third  (1/3) of the  replacement  cost of the
Premises,  including the replacement cost of the Tenant Improvements paid for by
Landlord.  In the event the Premises (i) are more than partially  destroyed,  or
(ii) the  repairs  cannot be made  within  twelve  (12)  months from the date of
destruction  as  reasonably  determined  by the  architect  responsible  for the
reconstruction  such determination to be made within sixty (60) days of the date
of destruction. Landlord shall not be required to restore Alterations or replace
Tenant's fixtures or personal  property.  In respect to any partial  destruction
which  Landlord is obligated to repair or may elect to repair under the terms of
this Article, the provision of Section 1932, Subdivision 2, and of Section 1933,
Subdivision  4, of the  Civil  Code of the  State of  California  and any  other
similarly  enacted  statute  are  waived by Tenant  and the  provisions  of this
Article 28 shall govern in the case of such  destruction.  Any disputes  between
Landlord and Tenant with respect to the degree of damage or  destruction  of the
Premises or the time  necessary  to rebuild  shall be  resolved  by  arbitration
pursuant to Section 47 of this Lease.

         B.  Destruction  by an Uninsured  Casualty:  In the event of a total or
partial  destruction  of the Premises by a casualty  for which  Landlord has not
received  insurance  proceeds  sufficient  to repair the  damage or  destruction
during  the Lease  Term and which  would  cost in  excess of Two  Hundred  Fifty
Thousand and No/100  Dollars  ($250,000.00)  to repair,  Landlord shall have the
option to terminate this Lease, unless Tenant agrees to contribute the amount of
such uninsured loss beyond the initial $250,000 to repair, which amount shall be
the sole  obligation  of Landlord.  Further if the  uninsured  damage can not be
repaired  within twelve (12) months from the date of  destruction  as reasonably
determined   by  the  architect   responsible   for  the   reconstruction   such
determination  to be made  within  sixty  (60) days of the date of  destruction,
either Landlord or Tenant shall have the option to terminate this lease.

                                    Page 22
<PAGE>

         C. Damage or Destruction at End of Term: If the Building or Premises is
damaged or destroyed  during the last twenty-four (24) months of the Term of the
Lease,  and the  Premises  or Building  cannot be fully  repaired or restored by
Landlord  within  ninety (90) days after the date of the damage or  destruction,
either  Landlord  or Tenant may  terminate  this Lease upon notice to the other,
provided,  that Tenant may prevent  Landlord's  termination  of this Lease under
this  Section  28.C by  exercising  Tenant's  right to extend  the Lease Term as
described in Section 37.

     29. Assignment or Sublease: 


         A.  Consent by  Landlord:  In the event  Tenant  desires to assign this
Lease or any interest therein including,  without limitation, a pledge, mortgage
or other hypothecation, or sublet the Premises or any part thereof, Tenant shall
deliver to  Landlord  executed  counterparts  of any such  agreement  and of all
ancillary  agreements with the proposed assignee or subtenant,  such assignee or
subtenant's most recent financial statements,  and any additional information as
reasonably  required  by Landlord to  determine  whether it will  consent to the
proposed  assignment  or  sublease.  The notice  shall give the name and current
address of the proposed assignee/subtenant, proposed use of the Premises, rental
rate and current financial statement; and upon request to Tenant, Landlord shall
be given additional  information as reasonably required by Landlord to determine
whether it will consent to the proposed  assignment or sublease.  Landlord shall
then  have  a  period  of ten  (10)  days  following  receipt  of the  foregoing
agreement,  statements and additional  information within which to notify Tenant
in writing that  Landlord  elects (i) to permit  Tenant to assign or sublet such
space to the named  assignee/subtenant  on the terms and conditions set forth in
the notice,  or (ii) to refuse consent,  which consent shall not be unreasonably
withheld or delayed. If Landlord should fail to notify Tenant in writing of such
election  within  said ten (10) day  period,  Landlord  shall be  deemed to have
elected  option (i) above.  Landlord's  consent (which must be in writing and in
form reasonably satisfactory to Landlord) to the proposed assignment or sublease
shall not be  unreasonably  withheld or delayed.  Tenant shall not  advertise or
publicize the availability of the Premises without prior notice to Landlord.

         B.  Assignment  or  Subletting  Consideration:  If Tenant shall assign,
sublease or  otherwise  transfer  all or any portion of the  Premises to a party
other than Tenant  Affiliate  (as defined in 29.E  below),  Landlord  and Tenant
shall evenly divide any rent or other consideration paid to Tenant in connection
with such assignment,  sublease or other transfer which is in excess of the base
rent due under this Lease,  after first  deducting out for the Tenant's  account
the cost of (i) broker's commissions paid by Tenant with regard to the transfer;
(ii) legal fees; (iii) the cost of improvements made to the Premises at Tenant's
expense  to the  extent  such  improvements  increase  the rent  paid  under the
sublease  over that which would have been paid without such  improvements;  (iv)
any tenant  improvements  made by Tenant at Tenant's  expense for the purpose of
transfer; (v) all rent paid by Tenant to Landlord while the Premises were vacant
prior to such  transfer;  and (vi) any  other  expenses  incurred  by  Tenant in
effectuating  the  transfer.  The  terms  of  this  section  shall  survive  the

                                    Page 23
<PAGE>

expiration or earlier  termination of the Lease. The above provision relating to
the allocation of bonus rent are  independently  negotiated  terms of the Lease,
constitute a material  inducement for the Landlord to enter into the Lease,  and
are agreed as between the parties to be commercially  reasonable.  No assignment
or subletting by Tenant shall relieve Tenant of any obligation under this Lease.
Any assignment or subletting which conflicts with the provisions hereof shall be
void.

         C. No Release:  Any  assignment  or sublease  shall be made only if and
shall  not  be  effective   until  the  assignee  or  subtenant  shall  execute,
acknowledge  and  deliver  to  Landlord  an  agreement,  in form  and  substance
satisfactory to Landlord,  whereby the assignee or subtenant shall assume all of
the  obligations of this Lease on the part of Tenant to be performed or observed
and shall be subject to all of the covenants,  agreements, terms, provisions and
conditions  contained in this Lease,  except as expressly  provided for therein.
Notwithstanding  any such sublease or assignment  and the  acceptance of rent by
Landlord from any subtenant or assignee, Tenant and any guarantor shall and will
remain  fully  liable  for the  payment  of the  rent  and  additional  rent due
hereunder,  and to  become  due  hereunder,  for the  performance  of all of the
covenants,  agreements, terms, provisions and conditions contained in this Lease
on the part of  Tenant to be  performed  and for all acts and  omissions  of any
licensee,  subtenant, assignee or any other person claiming under or through any
subtenant  or  assignee  that  shall be in  violation  of any of the  terms  and
conditions  of this  Lease,  and any  such  violation  shall be  deemed  to be a
violation by Tenant.  Tenant shall further  indemnify,  defend and hold Landlord
harmless from and against any and all losses,  liabilities,  damages,  costs and
expenses (including reasonable attorney fees) resulting from any claims that may
be made against  Landlord by the  proposed  assignee or subtenant or by any real
estate brokers or other persons claiming a commission or similar compensation in
connection with the proposed assignment or sublease.

         D. Effect of Default:  In the event of Tenant's default,  Tenant hereby
assigns all rents due from any  assignment or subletting to Landlord as security
for  performance  of its  obligations  under this Lease and Landlord may collect
such rents, except that Tenant may collect such rents unless a default occurs as
described  in  Article  22 and 24 above.  The  termination  of this Lease due to
Tenant's  default shall not  automatically  terminate any assignment or sublease
then in  existence;  at the election of Landlord,  such  assignment  or sublease
shall  survive  the  termination  of this Lease  and,  upon such  election,  the
assignee or subtenant  shall attorn to Landlord and Landlord shall undertake the
obligations  of the  Tenant  under the  sublease  or  assignment;  provided  the
Landlord shall not be liable for prepaid rent, or security deposits not received
by Landlord or other defaults of the Tenant to the subtenant or assignee, or any
acts or omissions of Tenant,  its agents,  employees,  contractors  or invitees.
Notwithstanding  anything to the  contrary  in this  Lease,  no event of default
shall be  deemed  to have  occurred  by  virtue  of any act or  omission  of any
subtenant or assignee of Tenant, unless Landlord has delivered to Tenant written
notice of such act or  omission,  and has given  Tenant  the  period(s)  of time
specified in Article 22 to cure such default.

                                    Page 24
<PAGE>

         E.  Excluded  Transfers:  Tenant  may  assign  this Lease or sublet any
portion of the Premises without  Landlord's  consent to any of the following (i)
any corporation  which  controls,  is controlled by or under common control with
Tenant;  (ii) any  corporation  resulting  from the merger or  consolidation  of
Tenant if (a) the  successor to Tenant has a net worth,  computed in  accordance
with generally accepted accounting principles,  at least equal to the greater of
(1) the net worth of Tenant  immediately  prior to such  transfer or (2) the net
worth  of  Tenant  herein  named  on the  date of  this  Lease,  and  (b)  proof
satisfactory to Landlord of such net worth shall have been delivered to Landlord
at least  ten (10) days  prior to the  effective  date of any such  transaction;
(iii) any person or entity which acquires all of the assets of Tenant as a going
concern of the business that is being  conducted on the Premises  (collectively,
"Tenant Affiliate"), provided that such assignee assumes in full the obligations
of Tenant under the Lease.

     30. Condemnation: If any part of the Premises shall be taken for any public
or quasi-public  use, under any statute or by right of eminent domain or private
purchase in lieu thereof,  and only a part thereof  remains which is susceptible
of occupation hereunder,  this Lease shall as to the part so taken, terminate as
of the day before  title  shall vest in the  condemnor  or  purchaser  ("Vesting
Date"),  and the Base Monthly Rent payable  hereunder  shall be adjusted so that
the Tenant  shall be  required to pay for the  remainder  of the Lease Term only
such portion of such Base Monthly Rent as the value of the part remaining  after
such taking bears to the value of the entire Premises prior to such taking;  but
in such event  Landlord and Tenant shall have the option to terminate this Lease
as of the Vesting Date. If all of the Premises, or such part thereof be taken so
that the  remaining  portion is  unusable  for  Tenant's  business  therein,  as
reasonably  determined by Tenant,  Tenant may terminate this Lease as of Vesting
Date. Landlord shall be entitled to any award paid for if the Premises is wholly
or partially condemned,  except that Tenant shall have the right to receive from
either the condemning  authority or Landlord,  as  applicable,  all proceeds and
other  compensation  received in connection with condemnation to the extent paid
for (i) any Tenant  Improvements  or  Alterations  made by or at the  expense of
Tenant;  (ii) Tenant's loss of goodwill;  (iii) Tenant's  relocation  costs; and
(iv) Tenant's loss of business and business  interruption.  Tenant hereby waives
the provisions of California Code of Civil  Procedures  Section 1265.130 and any
other  similarly  enacted statue are waived by Tenant and the provisions of this
Article 30 shall govern in the case of such destruction.

     31. Effects of Conveyance: The term "Landlord" as used in this Lease, means
only the owner for the time being of the  Premises so that,  in the event of any
sale or other  conveyance of the Premises,  or in the event of a master lease of
the Premises, the Landlord shall be and hereby is entirely freed and relieved of
all covenants and obligations of the "Landlord"  hereunder,  but only so long as
the new Landlord  expressly  assumes in writing all the  obligations of Landlord
under this Lease,  and  delivers to Tenant a written  agreement by which the new
Landlord assumes such obligations, and it shall be deemed and construed, without
further agreement between the parties 

                                    Page 25
<PAGE>

and the purchaser at any such sale,  or the master tenant of the Premises,  that
the  purchaser or master  tenant of the Premises has assumed and agreed to carry
out any and all  covenants and  obligations  of the Landlord  hereunder  arising
after the effective  date of the transfer to the new Landlord.  Such  transferor
shall  transfer and deliver  Tenant's  security  deposit to the purchaser at any
such  sale  or the  master  tenant  of the  Premises,  and  thereupon  the  such
transferor shall be discharged from any further liability in reference thereto.

     32.  Subordination:  Simultaneously  with  the  execution  of  this  Lease,
Landlord shall deliver to Tenant a  non-disturbance  agreement  from  Landlord's
existing lender or lenders, if any, in form and substance  acceptable to Tenant,
by which such lender or lenders agree not to disturb Tenant's  possession of the
Premises so long as Tenant is not in material default of the terms of this Lease
beyond any applicable  cure period at the time such lender or lenders  foreclose
on the  Premises.  This Lease shall be  subordinate  to any future ground lease,
deed of trust,  or other  hypothecation  for  security  only so long as Landlord
delivers  to  Tenant  prior to the  effective  of such  subordination  a written
non-disturbance  agreement, in form and substance acceptable to Tenant, by which
such  Lender or other party  agrees not to disturb  Tenant's  possession  of the
Premises if Tenant is not in material default of Tenant's obligations under this
Lease beyond any  applicable  cure period at the time such party becomes the fee
owner of the  Premises.  Subject to the above,  in the event  Landlord  notifies
Tenant in writing,  this Lease shall be subordinate to any ground Lease, deed of
trust, or other hypothecation for security now or hereafter placed upon the real
property of which the Premises  are a part and to any and all  advances  made on
the security thereof and to renewals, modifications, replacements and extensions
thereof.  Tenant agrees to promptly  execute and deliver any documents which may
be required to effectuate such subordination.

     33.  Waiver:  The waiver by  Landlord  or Tenant of any breach of any term,
covenant or condition,  herein  contained  shall not be deemed to be a waiver of
such term,  covenant or  condition or any  subsequent  breach of the same or any
other term, covenant or condition herein contained. The subsequent acceptance of
rent  hereunder by Landlord  shall not be deemed to be a waiver of any preceding
breach by Tenant of any term,  covenant or condition  of this Lease,  other than
the failure of Tenant to pay the  particular  rental so accepted,  regardless of
Landlord's  knowledge of such preceding breach at the time of acceptance of such
rent.  No payment by Tenant or receipt by Landlord  of a lesser  amount than any
installment  of rent due shall be deemed to be other than  payment on account of
the amount due.  No delay or omission in the  exercise of any right or remedy by
Landlord or Tenant shall impair such right or remedy or be construed as a waiver
thereof by the non-defaulting  party. No act or conduct of Landlord,  including,
without  limitation,  the acceptance of keys to the Premises,  shall  constitute
acceptance of the surrender of the Premises by Tenant before the Expiration Date
(only written notice from Landlord to Tenant of acceptance shall constitute such
acceptance of surrender of the Premises).  Landlord's  consent to or approval of
any act by Tenant which  require  Landlord's  consent or approvals  shall not be
deemed to waive or render  unnecessary  Landlord's consent to or approval of any
subsequent act by Tenant.

                                    Page 26
<PAGE>

     34.  Holding  Over:  Any holding over after the  termination  or Expiration
Date,  shall be  construed to be a tenancy  from month to month,  terminable  on
thirty (30) days  written  notice from either  party,  and Tenant shall pay Base
Monthly  Rent to  Landlord at a rate equal to one  hundred  twenty five  percent
(125%) of the Base Monthly Rent due in the month  preceding the  termination  or
Expiration  Date for the first two (2)  months of any hold over and one  hundred
fifty percent (150%) of the Base Monthly Rent  thereafter plus all other amounts
payable by Tenant under this Lease.  Any holding over shall  otherwise be on the
terms and conditions herein specified,  except those provisions  relating to the
Lease Term and any options to extend or renew,  which  provisions shall be of no
further force and effect  following the  expiration of the  applicable  exercise
period.

     35.  Successors and Assigns:  The covenants and conditions herein contained
shall,  subject to the  provisions  of Article 29,  apply to and bind the heirs,
successors, executors, administrators and assigns of all the parties hereto; and
all of the parties hereto shall be jointly and severally liable hereunder.

     36. Estoppel Certificates:  Tenant shall at any time during the Lease Term,
within ten (10) days following receipt of written notice from Landlord,  respond
to any request by Landlord for a statement in writing  certifying  (i) that this
Lease is unmodified  and in full force and effect (or, if modified,  stating the
nature of such modification);  (ii) the date to which the rent and other charges
are paid in advance, if any; (iii) acknowledging that there are not, to Tenant's
knowledge,  any uncured defaults on the part of Landlord hereunder or specifying
such defaults if they are claimed;  and (iv) such other  information as Landlord
may reasonably  request.  Any such statement may be conclusively  relied upon by
any prospective purchaser or encumbrancer of the Premises. Tenant also agrees to
provide the most current three (3) years of audited financial  statements within
five (5) days of a request by  Landlord  for  Landlord's  use in  financing  the
Premises with commercial lenders.

     37. Option to Extend the Lease Term: 

         A. Grant and Exercise of Option: Landlord hereby grants to Tenant, upon
and subject to the terms and  conditions  set forth in this  Article 37 four (4)
options (the  "Options")  to extend the Lease Term for an  additional  term (the
"Option  Term"),  each Option  Term shall be for a period of sixty (60)  months.
Each such Option shall be exercised, if at all, by written notice to Landlord no
earlier  than the date that is twenty four (24) months  prior to the  Expiration
Date  but no later  than  the  date  that is  twelve  (12)  months  prior to the
Expiration  Date.  Thirteen  (13) months prior to the  Expiration  Date Landlord
shall  provide  Tenant  with a written  notice of the fact that the Option  will
expire in thirty (30) days. If Tenant  exercises the Option,  each of the terms,
covenants  and  conditions  of this Lease except this Article shall apply during
the Option  Term as though the  expiration  date of the Option Term was the date
originally  set forth  herein as the  Expiration  Date,  provided  that the Base
Monthly Rent to be paid by Tenant during the Option Term shall be the greater of
(i) the Base 

                                    Page 27
<PAGE>

Monthly Rent payable on the Commencement Date, or (ii) ninety five percent (95%)
of the Fair Market  Rental,  as  hereinafter  defined,  for the Premises for the
Option  Term.  Anything  contained  herein to the contrary  notwithstanding,  if
Tenant is in monetary or material  non-monetary  default  beyond any  applicable
cure period under any of the terms, covenants or conditions of this Lease either
at the time Tenant  exercises the Option or at any time thereafter  prior to the
commencement date of the Option Term, Landlord shall have, in addition to all of
Landlord's  other  rights and  remedies  provided  in this  Lease,  the right to
terminate the Option upon notice to Tenant,  in which event the expiration  date
of this Lease shall be and remain the  Expiration  Date or the expiration of the
then relevant Option Term. As used herein, the term "Fair Market Rental" for the
Premises  shall mean the rental and all other  monetary  payments  including any
escalations and adjustments thereto (including without limitation Consumer Price
Indexing) then being obtained for leases of space  comparable in age and quality
to the  Premises in the  locality of the  Building  that  Landlord  could obtain
during the Option Term from a third party desiring to lease the Premises for the
Option Term based upon the current use and other potential uses of the Premises.
The appraisers shall be instructed that the foregoing five percent (5%) discount
is intended to reduce comparable rents which include (i) brokerage  commissions,
(ii) tenant improvement allowances,  and (iii) vacancy costs, to account for the
fact that Landlord will not suffer such costs in the event Tenant  exercises its
Option. The Fair Market Rental shall specifically  exclude any additional rental
attributable to the value of the Tenant  Improvements or Alterations paid for by
Tenant.

         B. Determination of Fair Market Rental: If Tenant exercises the Option,
Landlord  shall send to Tenant a notice setting forth the Fair Market Rental for
the Premises for the Option Term within thirty (30) days of Tenant's exercise of
the  Option.  If Tenant  disputes  Landlord's  determination  of the Fair Market
Rental for the Option Term, Tenant shall, within thirty (30) days after the date
of Landlord's  notice  setting forth the Fair Market Rental for the Option Term,
send to Landlord a notice stating that Tenant either (i) elects to terminate its
exercise  of the Option,  in which  event the Option  shall lapse and this Lease
shall  terminate on the  Expiration  Date,  or (ii)  disagrees  with  Landlord's
determination  of Fair  Market  Rental for the Option Term and elects to resolve
the  disagreement  as provided in Article 37.C below. If Tenant does not send to
Landlord a notice as provided in the previous sentence, Landlord's determination
of the Fair Market  Rental shall be the basis for  determining  the Base Monthly
Rent to be paid by Tenant  hereunder during the Option Term. If Tenant elects to
resolve the  disagreement  as provided in Article 37.C below and such procedures
shall not have been concluded prior to the commencement date of the Option Term,
Tenant shall pay as Base Monthly Rent to Landlord the rent due hereunder  during
the month preceding the Expiration  Date. If the amount of Fair Market Rental as
finally  determined  pursuant to Article 37.C below is greater  than  Landlord's
determination,  Tenant shall pay to Landlord the  difference  between the amount
paid by Tenant  and the he rent due  hereunder  during the month  preceding  the
Expiration  Date within  thirty (30) days after the  determination.  If the Fair
Market  Rental  as  finally  determined  in  Article  37.C  below  is less  than
Landlord's  determination,  the difference between the amount paid by Tenant and
the Fair Market  Rental as so determined in

                                    Page 28
<PAGE>

Article 37.C below shall be credited  against the next  installments of rent due
from Tenant to Landlord hereunder.

         C.  Resolution  of a  Disagreement  over the Fair  Market  Rental:  Any
disagreement regarding the Fair Market Rental shall be resolved as follows:

                    1.  Within  thirty  (30) days  after  Tenant's  response  to
Landlord's notice to Tenant of the Fair Market Rental, Landlord and Tenant shall
meet no less than two (2) times,  at a  mutually  agreeable  time and place,  to
attempt to resolve any such disagreement.

                    2. If within the thirty  (30) day period  referred to in (i)
above, Landlord and Tenant can not reach agreement as to the Fair Market Rental,
they shall each select one appraiser to determine the Fair Market  Rental.  Each
such  appraiser  shall arrive at a  determination  of the Fair Market Rental and
submit their  conclusions  to Landlord and Tenant  within thirty (30) days after
the  expiration  of the thirty (30) day  consultation  period  described  in (i)
above.

                    3. If only one  appraisal is submitted  within the requisite
time period, it shall be deemed to be the Fair Market Rental. If both appraisals
are submitted  within such time period,  and if the two  appraisals so submitted
differ by less than ten percent  (10%) of the higher of the two,  the average of
the two shall be the Fair Market Rental.  If the two  appraisals  differ by more
than ten percent (10%) of the higher of the two, then the two  appraisers  shall
immediately select a third appraiser who shall within thirty (30) days after his
or her selection shall select one of the two (2) existing determinations of Fair
Market Rental as correct.  This third  appraiser's  conclusion shall be the Fair
Market Rental.

                    4. All appraisers  specified  pursuant to this Article shall
be members of the  American  Institute of Real Estate  Appraisers  with not less
than five (5) years experience  appraising  office and industrial  properties in
the Santa Clara Valley.  Each party shall pay the cost of the appraiser selected
by such party and one-half of the cost of the third appraiser.

     38. Tenant's Right of First Refusal:

         A. Grant.  Landlord  hereby  grants to Tenant a right of first  refusal
during the Term of this Lease and any extension thereof to purchase the Premises
("Right of First Refusal to Purchase").

         B.  Covenants of Landlord.  Landlord  hereby  covenants and agrees with
Tenant that if, during the Term of the Lease,  Landlord shall receive or solicit
a bona fide offer from a  prospective  buyer to  purchase  either the  Premises,
Landlord  shall furnish  Tenant with a copy of the proposed  contract and notify
Tenant of the intention of Landlord to accept the same (the "Notice of Intention
to Sell").  Such Notice of Intention to Sell shall contain all material business
terms on which 

                                    Page 29
<PAGE>

Landlord  intends  to sell the  Premises.  Landlord  shall not sell the space in
question  to anyone  other  than  Tenant  without  first  providing  Tenant  the
opportunity  to buy the space in  question  upon the same  terms and  conditions
described in the Notice of Intention to Sell.

that  Tenant is not in  default  under the terms and  conditions  of this  Lease
beyond any applicable grace periods, Tenant may exercise Tenant's Right of First
Refusal to Purchase by providing  Landlord with written  notice  thereof  within
fifteen (15) days of Tenant's  receipt of the Notice of Landlord's  Intention to
Sell.  If Tenant does not exercise  its Right of First Offer to Purchase  within
said  fifteen (15) day period,  then  Landlord  shall be relieved of  Landlord's
obligation  to offer the space  identified in the Notice of Intention to Sell to
Tenant, except as provided for in Section 38.E below.

         D.  Terms for Right of First  Refusal  to  Purchase.  In the event that
Tenant exercises Tenant's Right of First Refusal to Purchase,  Tenant's purchase
shall be on all of the same terms and  conditions  as are offered to a bona-fide
third-party  purchaser  of the space  identified  in the Notice of  Intention to
Sell.

         E. Continuing Right. In no event shall Tenant's failure to exercise its
Right of First  Refusal  to  Purchase  be deemed a waiver or  relinquishment  by
Tenant of  Tenant's  Right of First  Refusal  to  Purchase  should (i) the space
identified in the Notice of Intention to Sell be offered for sale to a potential
purchaser  other  than the  purchaser  specified  in the  Notice  of  Landlord's
Intention  to Sell during the Term of this Lease or any  extension  thereof,  or
(ii) the space  identified  in the  Notice of  Landlord's  Intention  to Sell be
offered for sale to any purchaser on terms different than those specified in the
Notice of  Landlord's  Intention  to Sell  during  the Term of this Lease or any
extension thereof.

         F.  Exclusive  Nature of Option.  Landlord  represents  and warrants to
Tenant that no party  other than Tenant has any option,  right of first offer or
right of first refusal to purchase the Premises.  Landlord  hereby  covenants to

purchaser  or  successor  of such  sale or  foreclosure)  (i)  any  transfer  of
ownership of the Premises by a judicial  foreclosure  sale or sale pursuant to a
power  of  sale  provision  in any  relevant  deed of  trust  or  mortgage  lien

immediate family member of Sobrato, (iii)

any immediate family member of Sobrato, (iv) any partnership in which Sobrato or
any immediate  family member,  either  directly or indirectly  (e.g.,  through a
partnership or corporate entity or a trust) retains a general partner  interest,
and/or (v) any corporation under the control, either directly or indirectly,  by

     39.  Options:  Except  with  respect to any Tenant  Affiliate,  all Options

          EXHIBIT "B" - Formula for Determination of Base Monthly Rent



After  receipt of the final  pricing  for the  Building  Shell,  Landlord  shall
determine  Total Project  Costs (as defined  below) based on  competitive  bids.
During  this  period  Landlord  shall also  solicit  permanent  loan quotes from
institutional lenders to determine the best available financing.  Based on these
inputs  Landlord  shall then apply the  following  formula to determine the Base
Monthly Rent due under this Lease.

Base  Monthly  Rent  shall be equal to one  hundred  twenty  percent  of (i) the
product  of the (i)  Total  Project  Costs as  defined  below  and (ii) the best
non-participating  ten (10) year fixed rate  permanent  loan constant  available
prior to the start of construction of the Option Building.  The determination of
which loan comprises the best available financing shall be made in good faith by
both  Landlord  and Tenant.  The parties  acknowledge  that it is their  current
intention  that such  amortization  schedule  shall be for a  minimum  period of
twenty  (20)  years and  Landlord  shall  use its best  efforts  to obtain  such
financing.

Total Project Costs shall be equal to the sum of (i) the value of the land based
on a land value of Nine and 90/100  Dollars  ($9.90) per square  foot,  (ii) the
Building Shell Allowance, (iii) fees for building permits, licenses, inspection,
utility  connections or extensions,  and any other fees imposed by  governmental
entities, (iv) fees of engineers,  architects,  consultants and others providing
professional  services in connection with the construction of the Building,  (v)
construction  loan  interest paid by Landlord  including  interest on Landlord's
equity with  respect to the  construction  of the  Building,  calculated  at the
reference  rate  charged by Union  Bank plus one  percent  (1%),  (vi) loan fees
payable for the  construction  and/or permanent loan for the Building (vii) real
property taxes and assessments levied against the Property during the period the
Building is constructed,  (viii) liability and builders risk insurance  premiums
paid by Landlord with respect to the construction of the Building, and (ix) real
estate  leasing  commissions  or fees  payable by Landlord  with  respect to the
Building.

For example,  if Total Project Costs were $14,000,000,  and Landlord was able to
obtain a 7.75% loan with a 20 year amortization,  the Base Monthly Rent would be
120% X ($14,000,000 X .008209), or $137,911.

     1.  Parties:  THIS  LEASE,  is entered  into on this 24th day of May,  1996
("Execution  Date"),  between Sobrato  Development  Companies #871, a California
Limited Partnership,  whose address is 10600 North De Anza Boulevard, Suite 200,
Cupertino,  CA 95014 and  Komag  Incorporated,  a  Delaware  corporation,  whose
address  is 275 S.  Hillview  Drive,  Milpitas,  CA  95035,  hereinafter  called
respectively Landlord and Tenant.

     2.Premises:  Landlord  hereby  leases to  Tenant,  and  Tenant  hires  from
Landlord those certain Premises with the appurtenances,  situated in the City of
San Jose,  County of Santa Clara,  State of  California,  and more  particularly
described as follows, to-wit:

A 5.60 acre parcel ("Parcel") on the north side of Automation Parkway, San Jose,
California,  including  all  appurtenances  and buildings now or during the Term
located thereon.  Pursuant to the terms of this Lease,  Landlord is obligated to
construct a single story building of  approximately  81,778 rentable square feet
("Building"),  a parking  lot  consisting  of a minimum  of 303  parking  spaces
expandable to  approximately  341 spaces described as Building 11 on Exhibit "A"
attached  hereto.  Landlord  represents  and warrants  that  Landlord is the fee
simple owner of the Premises. Prior to the Commencement Date, Landlord shall use
its best  efforts  to  record a parcel  map to  subdivide  the  Parcel  into two
parcels,  one for the  Premises  and the  balance  for a second  building  to be
constructed  for Tenant  pursuant to that certain  lease  between the parties of
even date herewith.

     3. Use:  Tenant shall use the Premises only for the following  purposes and
shall not change the use of the Premises  without the prior  written  consent of
Landlord,  which consent shall not be unreasonably withheld or delayed:  Office,
research, development,  testing,  manufacturing,  ancillary warehouse, and other
legal uses.  Landlord makes no  representation or warranty that any specific use
of the Premises  desired by Tenant is permitted  pursuant to any Laws.  Landlord
represents  and warrants to Tenant that, as of the  Commencement  Date,  (i) the
Premises  are in  compliance  with all  municipal,  county,  state  and  federal
statutes,  laws,  ordinances,   including  zoning  ordinances,  and  regulations
governing and relating to the Building  Shell;  (ii) there shall exist no patent
or, to the best of Landlord's  knowledge,  latent  defect in the  Premises;  and
(iii) the Premises  shall be in good  condition  and repair and fit for Tenant's
particular purposes.  Landlord represents and warrants to Tenant that, as of the
Commencement Date, the land is zoned industrial ("I").

                                     Page 1
<PAGE>

     4. Term and Rental: The term ("Lease Term") shall be for one hundred twenty
(120)  months,  commencing  on the date on which the  Building  Shell and Tenant
Improvements  are  Substantially  Complete  as  defined  in  Article  7.H  below
("Commencement  Date"),  and ending one hundred twenty (120) months  thereafter,
("Expiration  Date"). In addition to all other sums payable by Tenant under this
Lease, Tenant shall pay as base monthly rent ("Base Monthly Rent") below for the
Premises in an amount determined  pursuant to Exhibit "B" attached hereto.  Base
Monthly Rent shall  increase at the end of the  forty-second  and eighty  fourth
month of the Lease Term by the product of the Base  Monthly Rent payable for the
preceding month and one and 147/1000 (1.147). The parties agree to enter into an
amendment to this Lease  setting forth the exact amount of the Base Monthly Rent
payable during the Lease Term within fourteen (14) days following  determination
by Landlord.

Base Monthly Rent shall be due on or before the first day of each calendar month
during Lease Term.  All sums payable by Tenant under this Lease shall be paid in
lawful money of the United States of America,  without offset or deduction,  and
shall be paid to Landlord at the address specified in Article 1 of this Lease or
at such place or places as may be designated from time to time by Landlord. Base
Monthly  Rent for any  period  less than a  calendar  month  shall be a pro rata
portion of the monthly installment.

     A.  Adjustment for Variance in Building  Square  Footage:  In the event the
square  footage of the Building is other than 81,778  determined by  measurement
after completion of construction, within thirty (30) days after the Commencement
Date,  Landlord and Tenant shall execute an amendment to the Lease setting forth
the actual  rentable  square feet of the Building,  which  calculation  shall be
consistent  with the BOMA standard for  Industrial  Buildings  (i.e.  outside of
outside wall to outside of outside wall without deduction).

     5. Security Deposit: None required.

     6. Late Charges:  Tenant hereby acknowledges that late payment by Tenant to
Landlord of Base Monthly Rent and other sums due hereunder  will cause  Landlord
to incur costs not contemplated by this Lease, the exact amount of which will be
extremely  difficult to ascertain.  Such costs include,  but are not limited to,
administrative,  processing,  accounting charges, and late charges, which may be
imposed on Landlord by the terms of any contract,  revolving credit, mortgage or
trust deed  covering  the  Premises.  Accordingly,  if any  installment  of Base
Monthly  Rent or any other sum due from Tenant shall not be received by Landlord
or Landlord's  designee  within ten (10) days after Tenant's  receipt of written
notice  from  Landlord  that such  amount  is  delinquent,  Tenant  shall pay to
Landlord a late charge equal to five (5%)  percent of such overdue  amount which
late charge  shall be due and  payable  with the payment  then  delinquent.  The
parties  hereby  agree that such late charge  represents  a fair and  reasonable
estimate of the costs  Landlord  will incur by 

                                     Page 2
<PAGE>

reason of late  payment by Tenant.  Acceptance  of such late  charge by Landlord
shall in no event  constitute a waiver of Tenant's  default with respect to such
overdue amount, nor prevent Landlord from exercising any of the other rights and
remedies granted hereunder.

IT IS FURTHER MUTUALLY AGREED BETWEEN THE PARTIES AS FOLLOWS:

     7. CONSTRUCTION AND POSSESSION:

         A. Building Shell  Construction.  Landlord shall cause the shell of the

premises ("Tenant  Improvements").  The Tenant Improvements shall consist of all
those items not included  within in the scope of the Building  Shell  definition
pursuant to Article 7.A above and Exhibit "D". The Tenant  Improvement Plans and
Specifications  shall be  prepared  in  sufficient  detail to allow  Landlord to

                    ii.  Tenant  Improvements.  Within  fourteen (14) days after

         D. Final Pricing.

                    i.  Building  Shell.  Within  ten (10) days  after  Tenant's
approval of the preliminary cost estimate for the Building Shell, Landlord shall
submit to Tenant competitive bids from a minimum of three (3) subcontractors for
each aspect of the work which is to be performed.  Landlord must utilize the low
bid  in  each  case,   unless  Tenant   approves   Landlord's   use  of  another
subcontractor,  and  the  cost  of  the  Building  Shell  shall  be  based  upon
construction expenses equal to the sum of the bid amounts as approved by Tenant.
Upon Tenant's written  approval of the contract bids,  Landlord and Tenant shall
each be  deemed to have  given  their  approval  of the  final  Shell  Plans and
Specifications  on which the cost estimate was made,  and Landlord shall proceed

approval of the preliminary cost estimate for the Tenant Improvements,  Landlord
shall  submit  to  Tenant   competitive   bids  from  a  minimum  of  three  (3)
subcontractors  for each aspect of the work which is to be  performed.  Landlord
must utilize the low bid in each case, unless Tenant approves  Landlord's use of
another  subcontractor,  and the cost of the Tenant  Improvements shall be based
upon  construction  expenses  equal to the sum of the bid amounts as approved by
Tenant. Upon Tenant's written approval of the contract bids, Landlord and Tenant
shall  each  be  deemed  to  have  given  their  approval  of the  final  Tenant
Improvement  Plans and  Specifications  on which the cost estimate was made, and
Landlord  shall  proceed with the  construction  of the Tenant  Improvements  in

         E. Change  Orders.  Tenant shall have the right to order changes in the
manner  and  type  of   construction   of  the  Building  Shell  or  the  Tenant
Improvements.  Any change  orders  which are  submitted by Tenant after the date
which is ten (10) days after the  issuance by the City of San Jose of a building
permit for the  construction  of the  Building  Shell,  which  cause  Landlord's
construction  schedule to be delayed shall cause the Commencement  Date to occur

Tenant's  submitting any binding change order,  Landlord shall promptly  provide
Tenant with written  statements  of the cost to implement and the time delay and
increased  construction  costs associated with any proposed change order,  which
statements  shall  be  binding  on  Landlord.  If no  time  delay  or  increased

Date  associated  with such change order.  If ordered by Tenant,  Landlord shall
implement  such  change  order,   and  the  cost  of  constructing   the  Tenant
Improvements shall be increased in accordance with the cost statement previously
delivered by Landlord to Tenant for any such change order.

<PAGE>

request for payment which shall include and be  accompanied  by: (i)  Landlord's

Complete.  All costs for Tenant  Improvements  shall be fully  documented to and
verified by Tenant.  The amounts  charged to Tenant shall be limited as provided

         H.  Construction.  Landlord  shall  use its best  efforts  to  obtain a
building  permit  from the City of San Jose as soon as possible  after  Tenant's
approval of the Shell Plans and  Specifications.  The Building  Shell and Tenant
Improvements shall be deemed substantially complete  ("Substantially  Complete")
when  the  Building  Shell  and  Tenant  Improvements  have  been  substantially
completed  in  accordance  with the Shell  Plans and  Specifications  and Tenant
Improvement  Plans  and  Specifications,  as  evidenced  by  the  issuance  of a
certificate  of  occupancy or its  equivalent  by the  appropriate  governmental
authority for the Building Shell and Tenant Improvements,  and the issuance of a
certificate by Tenant's Architect  certifying that the Building Shell and Tenant
Improvements have been completed in accordance with the plans.

         I. Documents.  Landlord shall at all times keep one (1) complete set of
all contract  documents (i.e.,  approved  drawings,  shop and setting  drawings,
specifications, samples, addenda and change orders) current and in good order on
the job site. Such documents shall be available for review by representatives of
Tenant,  its consultants and any public  officials at any time.  Record drawings
marked  with all  changes  made  during the job shall be kept on the job site by
Landlord.  Upon  acceptance of the work, the record  document print set shall be
immediately  forwarded to Tenant's  Architect for changes to the originals.  The
changes shall be noted on the originals  and one (1) mylar  reproducible  set of
the  originals  shall be forwarded to Tenant.  Tenant shall be provided with two
(2) copies of these specifications.

         J.  Landlord  Overhead & Profit.  As  compensation  to Landlord for its
services as general  contractor for the Building Shell and Tenant  Improvements,
Landlord  shall be entitled to a fee as specified in the Fee Agreement  attached
as Exhibit "G".  Except as provided  therein,  Landlord 

                                     Page 6
<PAGE>

shall not be entitled to any other fee or payment from Tenant in connection with
Landlord's services as general contractor.

         K. Insurance/Indemnity.  Landlord shall indemnify,  protect, defend and
hold Tenant harmless from and against all liability,  cost,  expense,  or damage
(including,   without   limitation,   attorneys  fees)  arising  from:  (i)  the
construction  of the  Building  Shell or the  Tenant  Improvements;  or (ii) any
construction  defects,  or (iii) any failure to properly  construct the Building
Shell or Tenant  Improvements  in accordance  with the approved  Shell Plans and
Specifications or Tenant Improvement Plans and  Specifications.  Tenant's review
and  approval of any plans,  specifications,  or any other  documents  shall not
relieve   Landlord   from   Landlord's    obligations    under   the   foregoing
indemnification.  Landlord  shall procure (as a cost of the Building  Shell) and
keep in effect from the execution  date of this Lease until the  termination  of
this  Lease a "Broad  Form"  liability  insurance  policy in the amount of Three
Million  Dollars  ($3,000,000.00),  insuring all of Landlord's  activities  with
respect to the Building and Premises, including Landlord's indemnity obligations
under this Article 7.K. In addition,  Landlord  shall  procure (as a cost of the
Building Shell) builder's risk insurance, insuring the Building Shell and Tenant
Improvements  for their  full  replacement  cost while the  Building  and Tenant
Improvements are under construction,  and until the date that the fire insurance
policy described in Article 12 of the Lease is in full force and effect.

         L. Punchlist  Items.  After the Building Shell and Tenant  Improvements
are Substantially Complete,  Landlord shall immediately correct any construction
defect or other  "punchlist"  item which Tenant brings to Landlord's  attention.
All such  work  shall be  performed  in a manner  designed  to cause  the  least
possible interruption to Tenant and Tenant's activities on the Premises.

         M. Other Work by Tenant. All work not within the scope of work normally
constructed  by the  construction  trades  employed  on  the  Building  and  not
described in the Shell Plans and  Specifications or Tenant Improvement Plans and
Specifications,  such as furniture,  telephone  equipment,  telephone wiring and
office equipment work, shall be furnished and installed by Tenant.

         O. Parking Lot.  Landlord,  at Landlord's sole cost and expense,  shall
construct a parking lot, with a minimum of approximately  303 parking spaces, on
the Premises in the location set forth in Exhibit "C".  Landlord shall cause the
parking lot to comply in all respects with all  applicable  governmental  rules,
regulations,  and orders, and shall create a sufficient number of parking spaces
to comply with all governmental requirements in connection with the Building.

                                     Page 7
<PAGE>

         8.  Acceptance of Possession and Covenants to Surrender:  Tenant agrees
on Expiration Date, or on the sooner termination of this Lease, to surrender the
Premises to Landlord in good  condition  and repair,  reasonable  wear and tear,
actions of Landlord or Landlord's  Parties,  or damage due to casualty excepted.
"Good  Condition" shall mean that the interior walls of all office and warehouse
areas, the floors of all office and warehouse areas, all suspended  ceilings and
carpeting will be cleaned and free of any major defacements. Tenant on or before
the Expiration  Date or sooner  termination of this Lease,  shall remove all its
personal  property and trade  fixtures from the  Premises,  and all property and
fixtures not so removed shall be deemed to be abandoned by Tenant.  Tenant shall
ascertain  from  Landlord  at the time  Tenant  desires  to make any  Alteration
(including  Permitted  Alterations),  whether  Landlord  desires  to  have  such
Alteration  removed at the  Expiration  Date or to cause Tenant to surrender the
Alteration to Landlord. If Landlord so notifies Tenant in writing within fifteen
(15) days after  Tenant's  notice to Landlord  that Tenant  intends to alter the
Building,  then Tenant shall remove such Alteration,  as Landlord may require in
such written notice,  and shall repair and restore said Building or such part or
parts thereof before the Expiration  Date at Tenant's sole cost and expense.  If
Landlord has not provided  Tenant with such written  notice  within said fifteen
(15) day period,  then Tenant shall have no obligation to remove such Alteration
from the Premises upon the Expiration Date or earlier termination of this Lease.
Notwithstanding the terms of this Article 8, Tenant shall not have an obligation
to remove any Tenant  Improvements  installed prior to the first  anniversary of
the Commencement Date from the Premises at any time.


         9. Uses Prohibited: Tenant shall not commit, or suffer to be committed,
any waste upon the said Premises,  or any nuisance, or allow any sale by auction
upon the Premises, or allow the Premises to be used for any unlawful purpose, or
place any loads upon the floor,  walls, or ceiling which endanger the structure,
or use any machinery or apparatus  which will in any manner vibrate or shake the
Premises.  Except for  materials  which may be stored in the enclosed  tank farm
area outside the Building, no materials,  supplies, equipment, finished products
or semi-finished  products, raw materials or articles of any nature or any waste
materials,  refuse,  scrap or debris shall be stored upon or permitted to remain
on any portion of the Premises outside of the Building proper without Landlord's
prior approval, which approval shall not be unreasonably withheld.

         10. Alterations and Additions:  Except for those improvements installed
prior  to  the  first   anniversary  of  the  Commencement  Date  and  Permitted
Alterations (as defined below), Tenant shall not make, or suffer to be made, any
alteration  or  addition  to the  said  Premises  ("Alterations"),  or any  part
thereof,  without (i) the written  consent of Landlord  first had and  

                                     Page 8
<PAGE>

obtained,  which consent shall not be unreasonably withheld or delayed, and (ii)
delivering to Landlord the proposed  architectural and structural plans, if any,
for all such  Alterations.  After having  obtained  Landlord's  consent,  Tenant
agrees  that it shall not  proceed  to make such  Alterations  until  Tenant has
obtained all required governmental approvals and permits.  Tenant further agrees
to provide Landlord (i) written notice of the anticipated  start date and actual
start date of the work,  and (ii) a complete set of half-size (15" X 21") vellum
as-built  drawings.  All  Alterations  shall be constructed  in compliance  with
applicable  buildings codes and laws.  Alterations which are not to be deemed as
trade  fixtures  shall  include  heating,  lighting,   electrical  systems,  air
conditioning,  partitioning,  carpeting,  or any  other  installation  which has
become affixed to the Premises. All Alterations shall be maintained, replaced or
repaired  by Tenant at  Tenant's  sole cost and  expense,  except as provided in
Section  11 below.  Notwithstanding  the above,  Tenant  shall have the right to
remove any trade fixtures,  furniture,  or process  equipment paid for by Tenant
from the Premises at the  expiration  of the Lease,  which items shall  include,
without  limitation,  the items set forth in  Exhibit  "F"  attached  hereto and
incorporated herein by this reference.

         Notwithstanding the foregoing, Tenant shall have the right, without the
prior written  consent of Landlord,  to make certain  alterations,  additions or
improvements (the "Permitted  Alterations") which (i) do not affect the Building
systems or structural components of the Building and (ii) which cost less, on an
individual basis, than One Hundred Fifty Thousand Dollars  ($150,000),  provided
that each such Permitted  Alteration is otherwise  performed in accordance  with
the  terms  of  this  Section  10.  Ownership  of  any  Alterations,   Permitted
Alterations  or Tenant  Improvements  paid for by Tenant  shall remain in Tenant
throughout  the Term of this Lease,  and Tenant shall be entitled to the benefit
of any  depreciation  or other tax benefits  arising  therefrom,  provided  that
Landlord  shall,  upon the  Expiration  Date or earlier  termination of the Term
hereof,  become the owner of any Alterations or Tenant  Improvements made to the
Premises which, pursuant to the terms of this Lease, are left on the Premises by
Tenant.  Tenant shall give Landlord at least ten (10) days' prior written notice
of any Alteration or Permitted  Alteration so that Landlord can post a notice of
non-responsibility with respect thereto.

     11. Maintenance of Premises:

         A.  Tenant's  Obligations:  Tenant  shall,  at its sole cost,  keep and
maintain and repair and said Premises and  appurtenances  and every part hereof,
including but not limited to, roof membrane, glazing, sidewalks,  parking areas,
telephone,   plumbing,   electrical  and  HVAC  systems,   and  all  the  Tenant
Improvements in good and sanitary  order,  condition,  and repair.  Tenant shall
enter into a service  contract  with a  licensed  air-conditioning  and  heating
contractor  which contract shall provide for maintenance of all air conditioning
and heating  equipment  at the  Premises in  accordance  with  general  industry
practices.  Tenant  shall  pay the  cost of all  air-conditioning  heating,  and
elevator  equipment repairs which are either excluded from such service contract
or any existing equipment warranties. All wall surfaces and floor tile are to be
maintained  in an as good a condition 

                                     Page 9
<PAGE>

as when Tenant took possession free of holes, gouges, or defacements, except for
damage  resulting  from  normal  wear and tear,  casualty  or other acts of God,
Landlord,  Landlord's  agents,  employees,  contractors  or invitees  ("Landlord
Parties") In no event,  however,  shall Tenant's obligation to repair under this
subsection  extend to (i) damage and repairs covered under any insurance  policy
carried by Landlord in connection with the Building; (ii) damage caused in whole
or in part by the  negligence  or willful  misconduct  of Landlord or Landlord's
agents, employees,  invitees or licensees,  (iii) reasonable wear and tear; (iv)
conditions  covered under any warranties of  contractors;  or (v) damage by fire
and other casualties,  or acts of governmental  authorities,  or acts of God and
the elements.

Tenant  shall  also  be  responsible,  at its  sole  cost  and  expense  for the
preventive  maintenance of the membrane of the roof, which  responsibility shall
be deemed  properly  discharged  if (i) Tenant  contracts  with a licensed  roof
contractor  who is  reasonably  satisfactory  to both  Tenant and  Landlord,  at
Tenant's  sole cost, to inspect the roof membrane at least every six (6) months,
with the first inspection due the sixth (6th) month after the Commencement Date,
and (ii) Tenant  performs,  at Tenant's sole cost,  all  preventive  maintenance
recommendations  made by such  contractor  within a  reasonable  time after such
recommendations are made. Such preventive maintenance might include acts such as
clearing  storm  gutters and  drains,  removing  debris from the roof  membrane,
trimming trees overhanging the roof membrane, applying coating materials to seal
roof penetrations,  repairing blisters, and other routine measures.  Tenant make
available for Landlord's  inspection such preventive  maintenance  contracts and
paid invoices for the recommended work. Tenant agrees, at its expense, to water,
maintain and replace,  when necessary,  any shrubbery and  landscaping.  Nothing
herein  shall  require   either   Landlord  or  Tenant  to  replace  any  Tenant
Improvements.

         B. Landlord's  Obligations:  Landlord at its sole cost and expense, and
without  reimbursement of all or any such costs from Tenant,  shall (i) maintain
in good  condition,  order,  and repair,  and replace as and when  necessary the
structural portions of the building including:  the foundation,  exterior walls,
structure and structural members,  and roof structure of the Building;  and (ii)
repair and damage  caused by the acts or  omissions  of Landlord  or  Landlord's
Parties.  Subject to the obligations of Tenant to provide  periodic  inspections
and  perform  maintenance  of the  membrane of the roof in  accordance  with the
provisions  set forth in Article 11.A above,  Landlord shall also replace as and
when necessary, the membrane of the roof. Tenant may give Landlord notice of any
repairs or  replacements  that are required of Landlord  under the terms of this
Lease and Landlord  shall proceed  forthwith to effect the same with  reasonable
diligence.  In the event of an emergency  Tenant shall be empowered to undertake
immediate  repairs  of such  nature as would be  Landlord's  responsibility  and
notify Landlord promptly after such repairs have been undertaken.

     12. Hazard Insurance: 

         A. Tenant's Use: Tenant shall not use, or permit said Premises,  or any
part  thereof,  to 

                                    Page 10
<PAGE>

be used,  for any purpose other than that for which the said Premises are hereby
leased;  and no use shall be made or permitted to be made of the said  Premises,
nor acts done,  which will cause a cancellation of any insurance policy covering
said Building,  or any part thereof, nor shall Tenant sell or permit to be kept,
used or sold, in or about said Premises,  any article which may be prohibited by
the standard  form of fire  insurance  policies.  Tenant  shall  (subject to the
provisions of Article 17 as to  Alterations  required  which are not a result of
Tenant's  specific  use), at its sole cost and expense,  comply with any and all
reasonable   requirements,   pertaining  to  said  Premises,  of  any  insurance
organization  or company,  necessary for the  maintenance of reasonable fire and
public liability insurance, covering said Premises and appurtenances.

         B. Landlord's Liability Insurance.  Landlord shall procure and maintain
during  the Term of this  Lease a policy  of (i)  commercial  general  liability
insurance  having a combined  single limit for bodily injury and property damage
of not less than One Million Dollars ($1,000,000.00) per occurrence;  and (ii) a
general  aggregate  insurance in an amount of not less than Five Million Dollars
($5,000,000.00).  The policy  shall  provide  coverage  for blanket  contractual
liability  (except for the negligence or willful  misconduct of the  non-insured
party) premises and personal injury  coverage.  Landlord shall furnish to Tenant
prior to the Commencement  Date, and thereafter within thirty (30) days prior to
the  expiration of each such policy,  a certificate  of insurance  issued by the
insurance carrier of each policy of insurance carried hereunder.

         C. Property  Insurance:  Landlord  agrees to purchase and keep in force
fire, and extended coverage ("All Risk" excluding earthquake) insurance covering
the Premises  pursuant to the provisions of Article 10) in amounts not less than
the  replacement  cost of said  Premises as mutually  determined by Landlord and
Tenant.  Tenant agrees to pay to the Landlord as additional rent, on demand, the
full cost of said insurance as evidenced by insurance  billings to the Landlord,
and in the event of damage covered by said insurance  which does not result in a
termination  of this  Lease,  the amount of any  deductible  under such  policy,
provided such deductible is not greater than $20,000.00. Payment shall be due to
Landlord within ten (10) days after written invoice to Tenant.  It is understood
and agreed  that  Tenant's  obligation  under this  Article  will be prorated to
reflect the commencement and termination dates of this Lease.

         Notwithstanding  the  forgoing,  Tenant shall have the right to provide
the hazard  insurance  for the  Premises  provided  (i)  Tenant can obtain  such
insurance at a more favorable rate than Landlord;  (ii) the form of coverage and
insurer are  satisfactory  to Landlord  and its lender;  (iii)  Landlord and its
lender are named as additional insured; (iv) such insurance provides that it may
not be subject to  cancellation or change except after at least thirty (30) days
written  notice  to  Landlord;  and (v)  Tenant  has  delivered  to  Landlord  a
certificate  of insurance and additional  insured  endorsement  evidencing  such
policy is in effect.

         E.  Tenant's  Insurance:  In  addition,  Tenant  agrees to  insure  its
personal  property,  the 

                                    Page 11
<PAGE>

Tenant Improvements, any Alterations not owned by Landlord pursuant to the terms
of Article 10 and to obtain  worker's  compensation  and  public  liability  and
property  damage  insurance  for  occurrences  within the Premises with combined
limits for bodily injury and property damage of not less than  $1,000,000.00 per
occurrence and a general aggregate limit of not less than $5,000,000.00.  Tenant
shall name  Landlord  and  Landlord's  lender as an  additional  insured,  shall
deliver a copy of the policies and renewal  certificates  to Landlord.  All such
policies shall provide for thirty (30) days' prior written notice to Landlord of
any cancellation, termination, or reduction in coverage.

         D. Waiver: Landlord and Tenant hereby waive any and all rights each may
have  against  the  other on  account  of any loss or damage  occasioned  to the
Landlord or the Tenant as the case may be, or to the  Premises or its  contents,
and which may arise from any risk covered by their respective insurance policies
(or which would have been covered had such insurance policies been maintained in
accordance with this Lease),  as set forth above.  The parties shall obtain from
their respective  insurance companies a waiver of any right of subrogation which
said insurance  company may have against the Landlord or the Tenant, as the case
may be.

         E. General:  Insurance required hereunder shall be written by companies
licensed to do business in the state in which the  Premises are located and have
a General  Policyholder's rating of at least A8 (or such higher rating as may be
required  by a lender  having a lien on the  Property)  as set forth in the most
current issue of Best's Insurance  Guide. All insurance shall expressly  provide
that such  policies  shall not be cancelable or subject to reduction of coverage
or  otherwise  be subject to  modification  except  after thirty (30) days prior
written notice to any other party named as additional insureds.

     13. Taxes:  Tenant shall be liable for, and shall pay prior to delinquency,
all taxes and assessments levied against personal property and trade or business
fixtures,  and agrees to pay, as  additional  rental,  all real estate taxes and
assessment  installments  (special or general) or other  impositions  or charges
which may be levied on the  Premises,  upon the  occupancy  of the  Premises and
including any substitute or additional  charges which may be imposed during,  or
applicable to the Lease Term  including  real estate tax increases due to a sale
or other  transfer  of the  Premises,  as they appear on the City and County tax
bills during the Lease Term, and as they become due. It is understood and agreed
that  Tenant's  obligation  under this  Article  will be prorated to reflect the
Commencement and Expiration  Dates. If, at any time during the Lease Term a tax,
excise on rents,  business license tax, or any other tax, however described,  is
levied or assessed against Landlord,  as a substitute or addition in whole or in
part for taxes  assessed or imposed on land or  Buildings,  Tenant shall pay and
discharge  his pro rata share of such tax or excise on rents or other tax before
it becomes  delinquent.  In the event that a tax is placed,  levied, or assessed
against  Landlord and the taxing  authority  takes the position  that the Tenant
cannot  pay and  discharge  his pro  rata  share of such  tax on  behalf  of the
Landlord,  then at the sole election of the Landlord,  the Landlord may increase
the rental  charged  hereunder  by the exact amount of such tax and Tenant shall
pay such increase as

                                    Page 12
<PAGE>

additional  rent  hereunder.  Landlord  hereby  grants  to  Tenant  the right to
contest, on behalf and in the name of Landlord,  all taxes and assessments which
are imposed upon the Premises;  Landlord  agrees to cooperate  fully with Tenant
and to execute all documents  requested by Tenant,  in connection  with any such
contest.  If by virtue of any  application  or  proceeding  brought by  Landlord
results a reduction in the assessed value of the Building during the Lease Term,
Tenant agrees to reimburse  Landlord its  reasonable,  actual third party out of
pocket  costs  incurred by  Landlord  in  connection  with such  application  or
proceeding.

         Notwithstanding the foregoing,  the following shall not constitute real
estate taxes for the purposes of this Lease, and nothing  contained herein shall
be deemed to require Tenant to pay any of the following:  (i) any state,  local,
federal,  personal or  corporate  income tax measured by the income of Landlord;
(ii) any  estate or  inheritance  taxes;  (iii)  any  franchise,  succession  or
transfer  taxes;  (iv) interest on taxes or penalties  resulting from Landlord's
failure  to pay  taxes,  except to the extent  such  failure is due to  Tenant's
failure to pay such taxes to Landlord  when provided  under this Lease;  (v) any
assessments for public improvements or any taxes initiated by Landlord which are
essentially payments to a governmental agency for the right to make improvements
to the Building or surrounding  area, to the extent such  assessments are not in
effect as of the Execution Date and have not received the prior written  consent
of Tenant;  and (vi) any environmental tax, surcharge or other fee affecting the
Premises due to Landlord's  activities with respect to Hazardous  Materials,  as
opposed to general, areawide taxes or surcharges with respect to the remediation
or testing for Hazardous  Materials.  If any assessments  affecting the Premises
are payable in  installments  and Landlord  should  prepay such  assessments  in
advance of the date such  installments  would become due, Tenant shall be solely
responsible for the portion of such assessment that would have normally come due
as an installment, unless consented to by Tenant in writing.

         Notwithstanding  anything  to the  contrary  contained  in this  Lease,
Landlord  shall pay,  and  Tenant  shall have no  responsibility  for,  any real
property taxes  resulting from any change in ownership,  sale, or other transfer
of the  Premises or Building  during the initial Term of the Lease to the extent
that such amount reflects an assessed valuation of the Premises in excess of one
hundred  fifty  percent  (150%)  of  the  "Commencement   Date  Valuation."  The
"Commencement  Date Valuation" shall mean the assessed valuation of the Premises
(as  improved  with the  Building)  as  determined  by the  Santa  Clara  County
Assessor,  as of the first date after the Commencement Date that the Santa Clara
County Assessor  reassesses the Premises based on the completion of construction
of the Building and Tenant Improvements.

         14.  Utilities:  Tenant shall pay directly to the providing utility all
water, gas, heat, light,  power,  telephone and other utilities  supplied to the
Premises.  Except  for  any  damages  resulting  from  the  negligence,  willful
misconduct,  or breach of contract by Landlord,  or its agents,  or  contractors
Landlord  shall not be  liable  for a loss of or  injury  to  property,  however
occurring,  through or in connection with or incidental to furnishing or failure
to furnish any  utilities  to the

                                    Page 13
<PAGE>

Premises  and Tenant  shall not be entitled to  abatement  or  reduction  of any
portion of the Base  Monthly  Rent so long as any failure to provide and furnish
the utilities to the Premises is due to a cause beyond the Landlord's reasonable
control, and is not the result of the negligence,  willful misconduct, or breach
of contract by Landlord, or its agents, or contractors.

         In the  event  of any  interruption  in  utilities  or  services  to be
provided to the Premises,  Tenant's rights and remedies shall be as follows: (i)
if such  interruption is due to a failure of Tenant to pay the providing utility
when due, Base Rent due hereunder shall not be abated and Landlord shall have no
liability to Tenant  whatsoever as a result of such  interruption;  (ii) if such
interruption is due to the actions of Landlord or Landlord's  Parties,  the Base
Rent  hereunder  shall be  equitably  abated  as of the time  such  interruption
commenced and Landlord  shall be liable to Tenant for loss or injury to property
and Tenant's business as a result thereof;  (iii) if such interruption is due to
the failure of the  providing  utility to provide such utility or service to the
Premises and such  interruption  continues for more than ninety (90)  continuous
days,  then  Tenant  shall be entitled  to  terminate  this Lease by delivery of
written notice to Landlord within five (5) days following the expiration of such
ninety  (90) day  period;  and (iv) if such  interruption  is due to an event of
damage or destruction, the rights of the parties hereunder shall be as described
in Section 28 below.

     15. This paragraph intentionally left blank

     16. Free From Liens:  Except for obligations  arising from the construction
of the Building Shell , Tenant Improvements,  and parking lot, Tenant shall keep
the Premises  free from any liens arising out of any work  performed,  materials
furnished,  or obligations incurred by Tenant.  Landlord shall keep the Premises
free from any liens arising out of any work performed,  materials furnished,  or
obligations incurred in connection with the Building Shell, Tenant Improvements,
or parking  lot. In the event  Tenant  fails to  discharge or bond over any such
lien within  thirty  (30) days after  receiving  notice of the filing,  Landlord
shall be entitled to discharge  such lien at Tenant's  expense and all resulting
costs incurred by Landlord,  including  reasonable  attorney's fees shall be due
from Tenant as additional rent.

     17.  Compliance With  Governmental  Regulations:  Tenant shall, at its sole
cost and expense,  comply with all of the  requirements of all Municipal,  State
and Federal  authorities now in force, or which may hereafter be in force, which
are imposed as a result of Tenant's particular and specific use of the Premises,
and shall faithfully observe in the use of the Premises all Municipal ordinances
and State and Federal  statutes now in force or which may hereafter be in force.
The judgment of any court of competent jurisdiction,  or the admission of Tenant
in any action or proceeding against Tenant,  whether Landlord be a party thereto
or not, that Tenant has violated any such ordinance or statute in the use of the
Premises,  shall be conclusive of that fact as between  Landlord and Tenant.  In
the event an  Alteration  is required to the  Building  Shell by any law,  rule,

                                    Page 14
<PAGE>

ordinance  or decision not in effect as of the  Commencement  Date of this Lease
which is not imposed as a result of Tenant's  particular and specific use of the
Premises  (whether pursuant to Article 12 or this Article 17), Tenant shall only
be required  to pay that  portion of the cost equal to the product of such total
cost  multiplied  by a fraction,  the numerator of which is the number of months
remaining  in the Lease Term,  the  denominator  of which is the useful life (in
months) of the Alteration.

     18. Toxic Waste and Environmental Damage:          

         A.  Landlord's  Responsibility:  Landlord  represents  and  warrants to
Tenant that,  except as disclosed in the attached  environmental  studies  dated
June 18, 1990,  July 2, 1990,  July 25, 1994,  and the  Burrowing Owl study from
H.T. Harvey & Associates,  to the best of Landlord's knowledge, the Premises and
the Building,  as of the Commencement Date, do not contain any chemicals,  toxic
or hazardous  gaseous,  liquid or solid  materials or waste,  including  without
limitation,  material  or  substance  having  characteristics  of  ignitability,
corrosivity,  reactivity,  or  extraction  procedure  toxicity or  substances or
materials which are listed on any of the Environmental  Protection Agency's list
of hazardous  wastes or which are  identified  in Section 66680 through 66685 of
Title 22 of the  California  Administrative  Code, 42 U.S.C.  Sections  9601, et
seq., 49 U.S.C.  Sections  1801, et seq., 42 U.S.C.  Sections  6901, et seq., or
California Health and Safety Code Section 25117, as the same may be amended from
time to time ("Hazardous Materials").  Landlord shall indemnify, protect, defend
and hold  Tenant  harmless  from and  against all  liability,  cost,  damage and
expense (including, without limitation attorneys' fees) arising from either: (i)
the failure of the  representation  and warranty  contained  in the  immediately
preceding  sentence;  (ii) the presence of any Hazardous  Materials or Burrowing
Owls on or about the Premises on or prior to the Commencement Date; or (iii) the
presence,  release, storage or use of Hazardous Materials on the Premises during
the Term by any party other than Tenant, Tenant's agents, employees, contractors
or invitees ("Tenant's Parties").

         B. Tenant's Responsibility: Landlord hereby approves Tenant's use on or
about the  Premises of Hazardous  Materials  used by Tenant in  connection  with
Tenant's business. Tenant represents and warrants that Tenant will (i) adhere to
all reporting and inspection  requirements imposed by Federal,  State, County or
Municipal laws, ordinances or regulations and will make available for inspection
by Landlord a copy of any such  reports or agency  inspections,  (ii) obtain and
make  available  for  inspection  by Landlord  copies of all  necessary  permits
required for the use and handling  Hazardous  Materials on the  Premises,  (iii)
enforce  Hazardous  Materials  handling and disposal  practices  consistent with
industry  standards,  (iv)  surrender  the  Premises  free  from  any  Hazardous
Materials  arising  from  Tenant's  bringing,  using,  permitting,   generating,
emitting  or  disposing  of  Hazardous  Materials,  and (v)  properly  close the
facility   with  regard  to  Hazardous   Materials   including  the  removal  or
decontamination  of any  process  piping,  mechanical  ducting,  storage  tanks,
containers,  or trenches  which have come  become  contaminated  with  Hazardous
Materials and obtain a closure certificate from the local  administering  agency
prior to the Expiration

                                    Page 15
<PAGE>

Date to the extent required by Law.

         C.  Tenant's  Indemnity  Regarding  Hazardous  Materials:  Tenant shall
comply,  at its sole cost,  with all laws pertaining to, and shall indemnify and
hold Landlord harmless from any claims, liabilities,  costs or expenses incurred
or  suffered  by  Landlord  arising  from  such  bringing,   using,  permitting,
generating,  emitting or  disposing  of  Hazardous  Materials on the Premises by
Tenant  or  Tenant's  Parties.   Tenant's   indemnification  and  hold  harmless
obligations  include,  without  limitation,  (i)  claims,  liability,  costs  or
expenses  resulting  from or  based  upon  administrative,  judicial  (civil  or
criminal) or other action, legal or equitable,  brought by any private or public
person  under  common  law or under the  Comprehensive  Environmental  Response,
Compensation and Liability Act of 1980 ("CERCLA"), the Resource Conservation and
Recovery Act of 1980 ("RCRA") or any other Federal,  State,  County or Municipal
law,  ordinance  or  regulation,  (ii)  claims,  liabilities,  costs or expenses
pertaining to the identification,  monitoring,  cleanup, containment, or removal
of Hazardous Materials from soils, riverbeds or aquifers including the provision
of an alternative  public drinking water source,  and (iii) all reasonable costs
of defending such claims.

         D. Actual  Release by Tenant:  Tenant  agrees to notify  Landlord  upon
learning  of any  lawsuits  which  relate  to,  or  orders  which  relate to the
remedying  of, the actual  release by Tenant or  Tenant's  Parties of  Hazardous
Materials on or into the soils or groundwater  at or under the Premises.  Tenant
shall also provide to Landlord all notices required by Section 25359.7(b) of the
Health  and Safety  Code and all other  notices  required  by law to be given to
Landlord in connection with Hazardous Materials. Without limiting the foregoing,
Tenant  shall also deliver to Landlord,  within  twenty (20) days after  receipt
thereof,  any written notices from any  governmental  agency alleging a material
violation of, or material  failure to comply with,  any federal,  state or local
laws,  regulations,  ordinances or orders,  the violation of which of failure to
comply with,  poses a  foreseeable  and material  risk of  contamination  of the
groundwater or injury to humans (other than injury solely to Tenant,  its agents
and employees within the Improvements on the Property).

         In the event of any release on or into the Premises or into the soil or
groundwater under the Premises of any Hazardous Materials used, treated,  stored
or disposed of by Tenant, Tenant agrees to comply, at its sole cost and expense,
with all laws, regulations, ordinances and orders of any federal, state or local
agency relating to the monitoring or remediation of such Hazardous Materials. In
the event of any such release of Hazardous Materials,  Tenant agrees to meet and
confer with  Landlord  and its Lender to attempt to  eliminate  and mitigate any
financial  exposure to such  Lender and  resultant  exposure  to Landlord  under
California  Code of Civil  Procedure  section 736(b) as a result of such release
and promptly to take  reasonable  monitoring,  cleanup and remedial steps given,
inter alia,  the  historical  uses to which the Property has and continues to be
used,  the risks to  public  health  posed by the  release,  the then  available
technology and the costs of remediation, cleanup and monitoring, consistent with
acceptable  customary  practices for the type and severity of such contamination
and all applicable  laws.  Nothing in the preceding  sentence  shall  eliminate,

                                    Page 16
<PAGE>

modify or reduce the  obligation  of Tenant under  Article 18.B of this Lease to
indemnify  and hold  Landlord  harmless  from any claims  liabilities,  costs or
expenses  incurred or  suffered by Landlord as provided in Article  18.B of this
Lease.   Tenant  shall  provide  Landlord  prompt  written  notice  of  Tenant's
monitoring, cleanup and remedial steps. Tenant shall have the right, at Tenant's
expense and in Tenant's  name, to contest or object in good faith to any alleged
violation  by Tenant of any  applicable  law  relating  to the use of  Hazardous
Materials  by  appropriate  legal  proceedings  which  are  not  prejudicial  to
Landlord's   rights  if  (i)  Tenant  shall  have   demonstrated  to  Landlord's
satisfaction that such legal proceedings shall  conclusively  operate to prevent
enforcement prior to final  determination of any such proceedings.  In the event
that, by  non-performance of any such items, the Premises is subject to imminent
loss or  forfeiture,  Tenant shall perform any such act required by the relevant
governmental authority.

         In the absence of an order of any federal,  state or local governmental
or  quasi-governmental  agency  relating to the  cleanup,  remediation  or other
response action required by applicable law, any dispute arising between Landlord
and Tenant  concerning  Tenant's  obligation to Landlord under this Article 18.D
concerning  the Level,  method,  and manner of cleanup,  remediation or response
action required in connection  with such a release of Hazardous  Materials shall
be resolved by  mediation  and/or  arbitration  pursuant  to the  provisions  of
Article 45 of this Lease.

         E.  Environmental  Monitoring:  Landlord  and its agents shall have the
right,  at Landlord's  sole cost and expense,  (unless Tenant is in violation of
this Article 18 in which event such monitoring shall be at Tenant's  expense) to
inspect,  investigate,  sample and/or  monitor the Premises,  including any air,
soil,  water,  groundwater  or other  sampling  or any other  testing,  digging,
drilling or analysis to determine  whether Tenant is complying with the terms of
this Article 18. If Landlord discovers that Tenant is not in compliance with the
terms of this  Article  18, any such  reasonable  costs  incurred  by  Landlord,
including attorneys' and consultants' fees shall be due and payable by Tenant to
Landlord within thirty (30) days following Landlord's written demand therefore.

     19.  Indemnity:  As a material part of the  consideration to be rendered to
Landlord, Tenant hereby waives all claims against Landlord for damages to goods,
wares and  merchandise,  and all other personal  property in, upon or about said
Premises and for injuries to persons in or about said  Premises,  from any cause
except to the extent due to the negligence or willful  misconduct of Landlord or
Landlord's  Parties to the fullest  extent  permitted  by law,  and Tenant shall
indemnify and hold Landlord exempt and harmless from any damage or injury to any
person,  or to the goods,  wares and merchandise and all other personal property
of any person, arising from the use of the Premises, Building, and/or Project by
Tenant, its employees,  contractors,  agents and invitees or from the failure of
Tenant to keep the Premises in good  condition and repair,  as herein  provided,
except to the extent due to the negligence or willful  misconduct of Landlord or
Landlord's  Parties.  Further,  in the  event  Landlord  is  made  party  to any
litigation due to the acts or omission of Tenant,  its 

                                    Page 17
<PAGE>

employees,  contractors,  agents and  invitees,  Tenant will  indemnify and hold
Landlord  harmless from any such claim or liability  including  Landlord's costs
and expenses and reasonable attorney's fees incurred in defending such claims.

         Landlord  shall  defend,  indemnify  by counsel  acceptable  to Tenant,
protect Tenant, its officers, employees and agents harmless from and against any
liabilities,  loss,  cost,  damage,  injury  or  expense  (including  reasonable
attorneys'  fees and court  costs)  arising  out of or  related  to the  willful
misconduct or negligence of Landlord or Landlord's Parties.

     20. Advertisements and Signs: Tenant will not place or permit to be placed,
in, upon or about the exterior of the Building any signs which are prohibited by
the city or other governing  authority.  The Tenant will not place, or permit to
be placed,  upon the  exterior of the  Building,  any signs,  advertisements  or
notices  without the written consent of the Landlord as to type,  size,  design,
lettering,  coloring and  location,  and such  consent will not be  unreasonably
withheld.  Any sign so placed on the exterior of the Building shall be so placed
upon the  understanding  and  agreement  that  Tenant  will  remove  same at the
termination of the tenancy herein created and repair any damage or injury to the
exterior of the Building  caused  thereby,  and if not so removed by Tenant then
Landlord may have same so removed at Tenant's expense.

     21.  Attorney's  Fees:  In  case a suit  or  alternative  form  of  dispute
resolution  should  be  brought  for the  possession  of the  Premises,  for the
recovery  of any sum due  hereunder,  or  because  of the  breach  of any  other
covenant herein, the losing party shall pay to the prevailing party a reasonable
attorney's fee including the expense of expert witnesses,  depositions and court
testimony  as part of its costs  which  shall be deemed to have  accrued  on the
commencement of such action. In addition, the prevailing party shall be entitled
to recover all costs and expenses including reasonable  attorney's fees incurred
by the  prevailing  party in enforcing  any judgment or award  against the other
party. The foregoing provision relating to post-judgment costs is intended to be
severable from all other provisions of this Lease.

     22.  Tenant's  Default:  The  occurrence  of  any of  the  following  shall
constitute a material default and breach of this Lease by Tenant: a) Any failure
by Tenant to pay the rental or to make any other payment  required to be made by
Tenant hereunder,  where such failure continues for ten (10) days after Tenant's
receipt of written notice thereof by Landlord to Tenant;  b) A failure by Tenant
to observe  and  perform  any other  provision  of this Lease to be  observed or
performed  by Tenant,  where such failure  continues  for thirty (30) days after
Tenant's receipt of written notice thereof by Landlord;  provided, however, that
if the nature of such default is such that the same cannot  reasonably  be cured
within such thirty (30) day period  Tenant  shall not be deemed to be in default
if Tenant shall within such period commence such cure and thereafter  diligently
prosecute  the same to  completion;  c) The  making  by  Tenant  of any  general
assignment  for the benefit of creditors;  the filing by or against  Tenant of a
petition to have Tenant adjudged a bankrupt or of a 

                                    Page 18
<PAGE>

petition for  reorganization or arrangement under any law relating to bankruptcy
(unless,  in the case of a petition filed against Tenant,  the same is dismissed
after the filing);  the  appointment of a trustee or receiver to take possession
of  substantially  all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within ninety
(90)  days;  or  the  attachment,   execution  or  other  judicial   seizure  of
substantially  all of  Tenant's  assets  located at the  Premises or of Tenant's
interest in this Lease,  where such seizure is not discharged within ninety (90)
days.  The  notice  requirements  set  forth  herein  are in  lieu of and not in
addition to the notices  required by California Code of Civil Procedure  Section
1161. Any notice given by Landlord to Tenant  pursuant to California  Civil Code
1161 with  respect  to any  failure by Tenant to pay rent under this Lease on or
before the date the rent is due shall  provide  Tenant  with a period of no less
than ten (10) days to pay such rent or quit.

         A.  Remedies:  In the  event of any such  default  by  Tenant,  then in
addition  to any other  remedies  available  to  Landlord  at law or in  equity,
Landlord shall have the immediate  option to terminate this Lease and all rights
of Tenant hereunder by giving written notice of such intention to terminate.  In
the event that Landlord shall elect to so terminate this Lease then Landlord may
recover from Tenant:  a) the worth at the time of award of any unpaid rent which
had been earned at the time of such  termination;  plus b) the worth at the time
of award of the amount by which the unpaid  rent  which  would have been  earned
after termination until the time of award exceeds the amount of such rental loss
for the same period that Tenant proves could have been reasonably avoided;  plus
c) the worth at the time of award of the amount by which the unpaid rent for the
balance  of the Lease Term  after the time of award  exceeds  the amount of such
rental loss that Tenant  proves could be reasonably  avoided;  plus d) any other
amount necessary to compensate Landlord for all the detriment proximately caused
by Tenant's failure to perform its obligations  under this Lease or which in the
ordinary  course of  things  would be  likely  to  result  therefrom,  and e) at
Landlord's  election,  such  other  amounts  in  addition  to or in  lieu of the
foregoing as may be permitted  from time to time by applicable  California  law.
The term "rent",  as used herein,  shall be deemed to be and to mean the minimum
monthly installments of Base Monthly Rent and all other sums required to be paid
by Tenant pursuant to the terms of this Lease,  all other such sums being deemed
to be additional rent due hereunder. As used in (a) and (b) above, the "worth at
the time of award" is to be  computed  by  allowing  interest at the rate of the
discount  rate of the  Federal  Reserve  Bank of San  Francisco  plus  five (5%)
percent per annum. As used in (c) above,  the "worth at the time of award" is to
be  computed by  discounting  such  amount at the  discount  rate of the Federal
Reserve Bank of San Francisco at the time of award plus one (1%) percent.

         B.  Right to  Re-enter:  In the event of any such  default  by  Tenant,
Landlord shall also have the right,  with or without  terminating this Lease, to
re-enter the Premises  and remove all persons and  property  from the  Premises;
such  property  may be removed and stored in a public  warehouse or elsewhere at
the cost of and for the  account of Tenant and  disposed  of by  Landlord in any
manner permitted by law.

                                    Page 19
<PAGE>

         C.  Abandonment:  In the event of the  vacation or  abandonment  of the
Premises  by Tenant or in the event that  Landlord  shall  elect to  re-enter as
provided in Article 22.B above or shall take possession of the Premises pursuant
to legal  proceeding or pursuant to any notice provided by law, then if Landlord
does not elect to terminate  this Lease as provided in Article 22.A above,  then
the provisions of California  Civil Code Section 1951.4,  (Landlord may continue
the lease in effect after Tenant's breach and abandonment and recover rent as it
becomes  due,  if  Tenant  has a right to sublet  and  assign,  subject  only to
reasonable  limitations) as amended from time to time,  shall apply and Landlord
may from time to time, without terminating this Lease, either recover all rental
as it becomes  due or relet the  Premises  or any part  thereof for such term or
terms and at such rental or rentals and upon such other terms and  conditions as
Landlord  in its sole  discretion  may  deem  advisable  with the  right to make
alterations and repairs to the Premises.  In the event that Landlord shall elect
to so relet,  then rentals  received by Landlord  from such  reletting  shall be
applied:  first, to the payment of any indebtedness other than Base Monthly Rent
due  hereunder  from Tenant to Landlord;  second,  to the payment of any cost of
such reletting; third, to the payment of the cost of any alterations and repairs
to the  Premises;  fourth,  to the payment of Base  Monthly  Rent due and unpaid
hereunder;  and the  residue,  if any,  shall be held by Landlord and applied in
payment of future  Base  Monthly  Rent as the same may  become  due and  payable
hereunder.  Landlord shall have no obligation to relet the Premises  following a
default if Landlord  has other  available  space within the Building or Project.
Should that  portion of such rentals  received  from such  reletting  during any
month, which is applied by the payment of rent hereunder,  be less than the rent
payable  during  that  month by Tenant  hereunder,  then  Tenant  shall pay such
deficiency  to Landlord  immediately  upon demand  therefor  by  Landlord.  Such
deficiency  shall be  calculated  and paid  monthly.  Tenant  shall  also pay to
Landlord, as soon as ascertained, any costs and expenses incurred by Landlord in
such  reletting  or in making  such  alterations  and repairs not covered by the
rentals received from such reletting.

         D. No Termination:  No re-entry or taking possession of the Premises by
Landlord  pursuant to 22.B or 22.C of this  Article 22 shall be  construed as an
election to terminate  this Lease unless a written  notice of such  intention be
given to Tenant or unless  the  termination  thereof  be  decreed  by a court of
competent  jurisdiction.  Notwithstanding  any reletting without  termination by
Landlord  because of any default by Tenant,  Landlord may at any time after such
reletting elect to terminate this Lease for any such default.

     23.  Surrender of Lease:  The voluntary or other surrender of this Lease by
Tenant,  or a mutual  cancellation  thereof,  shall not  automatically  effect a
merger of the Lease with Landlord's  ownership of the Premises.  Instead, at the
option  of  Landlord,  Tenant's  surrender  may  terminate  all or any  existing
sublease or subtenancies,  or may operate as an assignment to Landlord of any or
all such subleases or subtenancies,  thereby  creating a direct  Landlord-Tenant
relationship between Landlord and any subtenants.

                                    Page 20
<PAGE>

     24. Habitual Default: Deleted.


     25. Landlord's  Default:  In the event of Landlord's failure to perform any
of its  covenants or  agreements  under this Lease,  Tenant shall give  Landlord
written notice of such failure and shall give Landlord  thirty (30) days to cure
such failure; provided, however, that if the nature of such default is such that
the same cannot  reasonably be cured within such thirty (30) day period Landlord
shall not be deemed to be in  default  if  Landlord  shall  within  such  period
commence such cure and thereafter  diligently  prosecute the same to completion.
In  addition,  upon any such  failure by  Landlord,  Tenant shall give notice by
registered or certified mail or national overnight courier service to any person
or entity  with a  security  interest  in the  Premises  ("Mortgagee")  that has
provided Tenant with written notice (including such Mortgagee's  address) of its
interest in the Premises,  and shall  provide such  Mortgagee a period of thirty
(30) days  beyond  the cure  period  provided  Landlord  hereunder  to cure such
failure. Tenant shall not make any prepayment of rent more than one (1) month in
advance without the prior written  consent of such Mortgagee.  Tenant waives any
right under  California Civil Code Section 1950.7 or any other present or future
law to the  collection  of any  payment or deposit  from such  Mortgagee  or any
purchaser  at a  foreclosure  sale  of such  Mortgagee's  interest  unless  such
Mortgagee or such  purchaser  shall have actually  received (or have credited to
it) and not refunded the applicable payment or deposit.

     26. Notices:  All notices,  demands,  requests,  or consents required to be
given under this Lease shall be sent in writing by U.S.  certified mail,  return
receipt  requested,  national  overnight courier service or by personal delivery
addressed to the party to be notified at the address for such party specified in
Article 1 of this Lease,  or to such other place as the party to be notified may
from  time to time  designate  by at least  five (5) days  prior  notice  to the
notifying party.

     27.  Entry by  Landlord:  Upon 24 hours prior  notice,  Tenant shall permit
Landlord and his agents to enter into and upon said  Premises at all  reasonable
times  subject to any  security  regulations  of Tenant for the  purposes of (i)
inspecting  the same,  (ii)  maintaining  the  Premises,  (iii) making  repairs,
alterations or additions to the Premises,  (iv) erecting additional  building(s)
and  improvements  on the land where the Premises are  situated,  or on adjacent
land owned by Landlord,  or (v) performing any obligations of the Landlord under
the Lease including  remediation of hazardous  materials if determined to be the
responsibility  of  Landlord,  without any  abatement  or  reduction  of rent or
without any liability to Tenant for any loss of occupation or quiet enjoyment of
the Premises  thereby  occasioned.  Tenant shall permit  Landlord and Landlord's
Parties,  at any  time  within  one  hundred  eighty  (180)  days  prior  to the
Expiration  Date,  unless  Tenant  has  exercised  its option to extend the term
pursuant  to  Section  37.A (or at any time  during  the  Lease if  Tenant is in
default hereunder beyond the applicable cure period), to place upon the Premises
"For  Lease"  signs  and  exhibit  the  Premises  to  real  estate  brokers  and
prospective  tenants at  reasonable  hours.  Landlord  agrees that  Landlord and
Landlord's  Parties shall conduct all of their  activities under this 

                                    Page 21
<PAGE>

Section 27 in a manner which  minimizes the  interruption  to Tenant or Tenant's
activities on the Premises.

     28. Destruction of Premises: 
         A.  Destruction  by an  Insured  Casualty:  In the  event of a  partial
destruction  of the  Premises  by a casualty  for which  Landlord  has  received
insurance  proceeds  sufficient to repair the damage or  destruction  during the
Lease  Term from any  cause,  Landlord  shall  forthwith  repair the same to the
extent of such  proceeds,  provided  such repairs can be made within twelve (12)
months from the date of  destruction  as reasonably  determined by the architect
responsible for the  reconstruction  such  determination to be made within sixty
(60) days of the date of destruction,  and such partial  destruction shall in no
way  annul or void  this  Lease,  except  that  Tenant  shall be  entitled  to a
proportionate  reduction of Base Monthly Rent while such repairs are being made,
such proportionate  reduction to be based upon the extent to which the making of
such  repairs  shall  interfere  with the  business  carried on by Tenant in the
Premises.  For  purposes  of  this  Article  "partial  destruction"  shall  mean
destruction of no greater than one-third  (1/3) of the  replacement  cost of the
Premises,  including the replacement cost of the Tenant Improvements paid for by
Landlord.  In the event the Premises (i) are more than partially  destroyed,  or
(ii) the  repairs  cannot be made  within  twelve  (12)  months from the date of
destruction  as  reasonably  determined  by the  architect  responsible  for the
reconstruction  such determination to be made within sixty (60) days of the date
of destruction. Landlord shall not be required to restore Alterations or replace
Tenant's fixtures or personal  property.  In respect to any partial  destruction
which  Landlord is obligated to repair or may elect to repair under the terms of
this Article, the provision of Section 1932, Subdivision 2, and of Section 1933,
Subdivision  4, of the  Civil  Code of the  State of  California  and any  other
similarly  enacted  statute  are  waived by Tenant  and the  provisions  of this
Article 28 shall govern in the case of such  destruction.  Any disputes  between
Landlord and Tenant with respect to the degree of damage or  destruction  of the
Premises or the time  necessary  to rebuild  shall be  resolved  by  arbitration
pursuant to Section 47 of this Lease.

         B.  Destruction  by an Uninsured  Casualty:  In the event of a total or
partial  destruction  of the Premises by a casualty  for which  Landlord has not
received  insurance  proceeds  sufficient  to repair the  damage or  destruction
during  the Lease  Term and which  would  cost in  excess of Two  Hundred  Fifty
Thousand and No/100  Dollars  ($250,000.00)  to repair,  Landlord shall have the
option to terminate this Lease, unless Tenant agrees to contribute the amount of
such uninsured loss beyond the initial $250,000 to repair, which amount shall be
the sole  obligation  of Landlord.  Further if the  uninsured  damage can not be
repaired  within twelve (12) months from the date of  destruction  as reasonably
determined   by  the  architect   responsible   for  the   reconstruction   such
determination  to be made  within  sixty  (60) days of the date of  destruction,
either Landlord or Tenant shall have the option to terminate this lease.

                                    Page 22
<PAGE>

         C. Damage or Destruction at End of Term: If the Building or Premises is
damaged or destroyed  during the last twenty-four (24) months of the Term of the
Lease,  and the  Premises  or Building  cannot be fully  repaired or restored by
Landlord  within  ninety (90) days after the date of the damage or  destruction,
either  Landlord  or Tenant may  terminate  this Lease upon notice to the other,
provided,  that Tenant may prevent  Landlord's  termination  of this Lease under
this  Section  28.C by  exercising  Tenant's  right to extend  the Lease Term as
described in Section 37.

     29. Assignment or Sublease: 
         A.  Consent by  Landlord:  In the event  Tenant  desires to assign this
Lease or any interest therein including,  without limitation, a pledge, mortgage
or other hypothecation, or sublet the Premises or any part thereof, Tenant shall
deliver to  Landlord  executed  counterparts  of any such  agreement  and of all
ancillary  agreements with the proposed assignee or subtenant,  such assignee or
subtenant's most recent financial statements,  and any additional information as
reasonably  required  by Landlord to  determine  whether it will  consent to the
proposed  assignment  or  sublease.  The notice  shall give the name and current
address of the proposed assignee/subtenant, proposed use of the Premises, rental
rate and current financial statement; and upon request to Tenant, Landlord shall
be given additional  information as reasonably required by Landlord to determine
whether it will consent to the proposed  assignment or sublease.  Landlord shall
then  have  a  period  of ten  (10)  days  following  receipt  of the  foregoing
agreement,  statements and additional  information within which to notify Tenant
in writing that  Landlord  elects (i) to permit  Tenant to assign or sublet such
space to the named  assignee/subtenant  on the terms and conditions set forth in
the notice,  or (ii) to refuse consent,  which consent shall not be unreasonably
withheld or delayed. If Landlord should fail to notify Tenant in writing of such
election  within  said ten (10) day  period,  Landlord  shall be  deemed to have
elected  option (i) above.  Landlord's  consent (which must be in writing and in
form reasonably satisfactory to Landlord) to the proposed assignment or sublease
shall not be  unreasonably  withheld or delayed.  Tenant shall not  advertise or
publicize the availability of the Premises without prior notice to Landlord.

         B.  Assignment  or  Subletting  Consideration:  If Tenant shall assign,
sublease or  otherwise  transfer  all or any portion of the  Premises to a party
other than Tenant  Affiliate  (as defined in 29.E  below),  Landlord  and Tenant
shall evenly divide any rent or other consideration paid to Tenant in connection
with such assignment,  sublease or other transfer which is in excess of the base
rent due under this Lease,  after first  deducting out for the Tenant's  account
the cost of (i) broker's commissions paid by Tenant with regard to the transfer;
(ii) legal fees; (iii) the cost of improvements made to the Premises at Tenant's
expense  to the  extent  such  improvements  increase  the rent  paid  under the
sublease  over that which would have been paid without such  improvements;  (iv)
any tenant  improvements  made by Tenant at Tenant's  expense for the purpose of
transfer; (v) all rent paid by Tenant to Landlord while the Premises were vacant
prior to such  transfer;  and (vi) any  other  expenses  incurred  by  Tenant in
effectuating  the  transfer.  The  terms  of  this  section  shall  survive  the

                                    Page 23
<PAGE>

expiration or earlier  termination of the Lease. The above provision relating to
the allocation of bonus rent are  independently  negotiated  terms of the Lease,
constitute a material  inducement for the Landlord to enter into the Lease,  and
are agreed as between the parties to be commercially  reasonable.  No assignment
or subletting by Tenant shall relieve Tenant of any obligation under this Lease.
Any assignment or subletting which conflicts with the provisions hereof shall be
void.

         C. No Release:  Any  assignment  or sublease  shall be made only if and
shall  not  be  effective   until  the  assignee  or  subtenant  shall  execute,
acknowledge  and  deliver  to  Landlord  an  agreement,  in form  and  substance
satisfactory to Landlord,  whereby the assignee or subtenant shall assume all of
the  obligations of this Lease on the part of Tenant to be performed or observed
and shall be subject to all of the covenants,  agreements, terms, provisions and
con[ditions  contained in this Lease,  except as expressly provided for therein.
Notwithstanding  any such sublease or assignment  and the  acceptance of rent by
Landlord from any subtenant or assignee, Tenant and any guarantor shall and will
remain  fully  liable  for the  payment  of the  rent  and  additional  rent due
hereunder,  and to  become  due  hereunder,  for the  performance  of all of the
covenants,  agreements, terms, provisions and conditions contained in this Lease
on the part of  Tenant to be  performed  and for all acts and  omissions  of any
licensee,  subtenant, assignee or any other person claiming under or through any
subtenant  or  assignee  that  shall be in  violation  of any of the  terms  and
conditions  of this  Lease,  and any  such  violation  shall be  deemed  to be a
violation by Tenant.  Tenant shall further  indemnify,  defend and hold Landlord
harmless from and against any and all losses,  liabilities,  damages,  costs and
expenses (including reasonable attorney fees) resulting from any claims that may
be made against  Landlord by the  proposed  assignee or subtenant or by any real
estate brokers or other persons claiming a commission or similar compensation in
connection with the proposed assignment or sublease.

         D. Effect of Default:  In the event of Tenant's default,  Tenant hereby
assigns all rents due from any  assignment or subletting to Landlord as security
for  performance  of its  obligations  under this Lease and Landlord may collect
such rents, except that Tenant may collect such rents unless a default occurs as
described  in  Article  22 and 24 above.  The  termination  of this Lease due to
Tenant's  default shall not  automatically  terminate any assignment or sublease
then in  existence;  at the election of Landlord,  such  assignment  or sublease
shall  survive  the  termination  of this Lease  and,  upon such  election,  the
assignee or subtenant  shall attorn to Landlord and Landlord shall undertake the
obligations  of the  Tenant  under the  sublease  or  assignment;  provided  the
Landlord shall not be liable for prepaid rent, or security deposits not received
by Landlord or other defaults of the Tenant to the subtenant or assignee, or any
acts or omissions of Tenant,  its agents,  employees,  contractors  or invitees.
Notwithstanding  anything to the  contrary  in this  Lease,  no event of default
shall be  deemed  to have  occurred  by  virtue  of any act or  omission  of any
subtenant or assignee of Tenant, unless Landlord has delivered to Tenant written
notice of such act or  omission,  and has given  Tenant  the  period(s)  of time
specified in Article 22 to cure such default.

                                    Page 24
<PAGE>

         E.  Excluded  Transfers:  Tenant  may  assign  this Lease or sublet any
portion of the Premises without  Landlord's  consent to any of the following (i)
any corporation  which  controls,  is controlled by or under common control with
Tenant;  (ii) any  corporation  resulting  from the merger or  consolidation  of
Tenant if (a) the  successor to Tenant has a net worth,  computed in  accordance
with generally accepted accounting principles,  at least equal to the greater of
(1) the net worth of Tenant  immediately  prior to such  transfer or (2) the net
worth  of  Tenant  herein  named  on the  date of  this  Lease,  and  (b)  proof
satisfactory to Landlord of such net worth shall have been delivered to Landlord
at least  ten (10) days  prior to the  effective  date of any such  transaction;
(iii) any person or entity which acquires all of the assets of Tenant as a going
concern of the business that is being  conducted on the Premises  (collectively,
"Tenant Affiliate"), provided that such assignee assumes in full the obligations
of Tenant under the Lease.

     30. Condemnation: If any part of the Premises shall be taken for any public
or quasi-public  use, under any statute or by right of eminent domain or private
purchase in lieu thereof,  and only a part thereof  remains which is susceptible
of occupation hereunder,  this Lease shall as to the part so taken, terminate as
of the day before  title  shall vest in the  condemnor  or  purchaser  ("Vesting
Date"),  and the Base Monthly Rent payable  hereunder  shall be adjusted so that
the Tenant  shall be  required to pay for the  remainder  of the Lease Term only
such portion of such Base Monthly Rent as the value of the part remaining  after
such taking bears to the value of the entire Premises prior to such taking;  but
in such event  Landlord and Tenant shall have the option to terminate this Lease
as of the Vesting Date. If all of the Premises, or such part thereof be taken so
that the  remaining  portion is  unusable  for  Tenant's  business  therein,  as
reasonably  determined by Tenant,  Tenant may terminate this Lease as of Vesting
Date. Landlord shall be entitled to any award paid for if the Premises is wholly
or partially condemned,  except that Tenant shall have the right to receive from
either the condemning  authority or Landlord,  as  applicable,  all proceeds and
other  compensation  received in connection with condemnation to the extent paid
for (i) any Tenant  Improvements  or  Alterations  made by or at the  expense of
Tenant;  (ii) Tenant's loss of goodwill;  (iii) Tenant's  relocation  costs; and
(iv) Tenant's loss of business and business  interruption.  Tenant hereby waives
the provisions of California Code of Civil  Procedures  Section 1265.130 and any
other  similarly  enacted statue are waived by Tenant and the provisions of this
Article 30 shall govern in the case of such destruction.

     31. Effects of Conveyance: The term "Landlord" as used in this Lease, means
only the owner for the time being of the  Premises so that,  in the event of any
sale or other  conveyance of the Premises,  or in the event of a master lease of
the Premises, the Landlord shall be and hereby is entirely freed and relieved of
all covenants and obligations of the "Landlord"  hereunder,  but only so long as
the new Landlord  expressly  assumes in writing all the  obligations of Landlord
under this Lease,  and  delivers to Tenant a written  agreement by which the new
Landlord assumes such obligations, and it shall be deemed and construed, without
further agreement between the parties

                                    Page 25
<PAGE>

and the purchaser at any such sale,  or the master tenant of the Premises,  that
the  purchaser or master  tenant of the Premises has assumed and agreed to carry
out any and all  covenants and  obligations  of the Landlord  hereunder  arising
after the effective  date of the transfer to the new Landlord.  Such  transferor
shall  transfer and deliver  Tenant's  security  deposit to the purchaser at any
such  sale  or the  master  tenant  of the  Premises,  and  thereupon  the  such
transferor shall be discharged from any further liability in reference thereto.

     32.  Subordination:  Simultaneously  with  the  execution  of  this  Lease,
Landlord shall deliver to Tenant a  non-disturbance  agreement  from  Landlord's
existing lender or lenders, if any, in form and substance  acceptable to Tenant,
by which such lender or lenders agree not to disturb Tenant's  possession of the
Premises so long as Tenant is not in material default of the terms of this Lease
beyond any applicable  cure period at the time such lender or lenders  foreclose
on the  Premises.  This Lease shall be  subordinate  to any future ground lease,
deed of trust,  or other  hypothecation  for  security  only so long as Landlord
delivers  to  Tenant  prior to the  effective  of such  subordination  a written
non-disturbance  agreement, in form and substance acceptable to Tenant, by which
such  Lender or other party  agrees not to disturb  Tenant's  possession  of the
Premises if Tenant is not in material default of Tenant's obligations under this
Lease beyond any  applicable  cure period at the time such party becomes the fee
owner of the  Premises.  Subject to the above,  in the event  Landlord  notifies
Tenant in writing,  this Lease shall be subordinate to any ground Lease, deed of
trust, or other hypothecation for security now or hereafter placed upon the real
property of which the Premises  are a part and to any and all  advances  made on
the security thereof and to renewals, modifications, replacements and extensions
thereof.  Tenant agrees to promptly  execute and deliver any documents which may
be required to effectuate such subordination.

     33.  Waiver:  The waiver by  Landlord  or Tenant of any breach of any term,
covenant or condition,  herein  contained  shall not be deemed to be a waiver of
such term,  covenant or  condition or any  subsequent  breach of the same or any
other term, covenant or condition herein contained. The subsequent acceptance of
rent  hereunder by Landlord  shall not be deemed to be a waiver of any preceding
breach by Tenant of any term,  covenant or condition  of this Lease,  other than
the failure of Tenant to pay the  particular  rental so accepted,  regardless of
Landlord's  knowledge of such preceding breach at the time of acceptance of such
rent.  No payment by Tenant or receipt by Landlord  of a lesser  amount than any
installment  of rent due shall be deemed to be other than  payment on account of
the amount due.  No delay or omission in the  exercise of any right or remedy by
Landlord or Tenant shall impair such right or remedy or be construed as a waiver
thereof by the non-defaulting  party. No act or conduct of Landlord,  including,
without  limitation,  the acceptance of keys to the Premises,  shall  constitute
acceptance of the surrender of the Premises by Tenant before the Expiration Date
(only written notice from Landlord to Tenant of acceptance shall constitute such
acceptance of surrender of the Premises).  Landlord's  consent to or approval of
any act by Tenant which  require  Landlord's  consent or approvals  shall not be
deemed to waive or render  unnecessary  Landlord's consent to or approval of any
subsequent act by Tenant.

     34.  Holding  Over:  Any holding over after the  termination  or Expiration
Date,  shall be  construed to be a tenancy  from month to month,  terminable  on
thirty (30) days  written  notice from either  party,  and Tenant shall pay Base
Monthly  Rent to  Landlord at a rate equal to one  hundred  twenty five  percent
(125%) of the Base Monthly Rent due in the month  preceding the  termination  or
Expiration  Date for the first two (2)  months of any hold over and one  hundred
fifty percent (150%) of the Base Monthly Rent  thereafter plus all other amounts
payable by Tenant under this Lease.  Any holding over shall  otherwise be on the
terms and conditions herein specified,  except those provisions  relating to the
Lease Term and any options to extend or renew,  which  provisions shall be of no
further force and effect  following the  expiration of the  applicable  exercise
period.

     35.  Successors and Assigns:  The covenants and conditions herein contained
shall,  subject to the  provisions  of Article 29,  apply to and bind the heirs,
successors, executors, administrators and assigns of all the parties hereto; and
all of the parties hereto shall be jointly and severally liable hereunder.

     36. Estoppel Certificates:  Tenant shall at any time during the Lease Term,
within ten (10) days following receipt of written notice from Landlord,  respond
to any request by Landlord for a statement in writing  certifying  (i) that this
Lease is unmodified  and in full force and effect (or, if modified,  stating the
nature of such modification);  (ii) the date to which the rent and other charges
are paid in advance, if any; (iii) acknowledging that there are not, to Tenant's
knowledge,  any uncured defaults on the part of Landlord hereunder or specifying
such defaults if they are claimed;  and (iv) such other  information as Landlord
may reasonably  request.  Any such statement may be conclusively  relied upon by
any prospective purchaser or encumbrancer of the Premises. Tenant also agrees to
provide the most current three (3) years of audited financial  statements within
five (5) days of a request by  Landlord  for  Landlord's  use in  financing  the
Premises with commercial lenders.

     37. Option to Extend the Lease Term: 
         A. Grant and Exercise of Option: Landlord hereby grants to Tenant, upon
and subject to the terms and  conditions  set forth in this  Article 37 four (4)
options (the  "Options")  to extend the Lease Term for an  additional  term (the
"Option  Term"),  each Option  Term shall be for a period of sixty (60)  months.
Each such Option shall be exercised, if at all, by written notice to Landlord no
earlier  than the date that is twenty four (24) months  prior to the  Expiration
Date  but no later  than  the  date  that is  twelve  (12)  months  prior to the
Expiration  Date.  Thirteen  (13) months prior to the  Expiration  Date Landlord
shall  provide  Tenant  with a written  notice of the fact that the Option  will
expire in thirty (30) days. If Tenant  exercises the Option,  each of the terms,
covenants  and  conditions  of this Lease except this Article shall apply during
the Option  Term as though the  expiration  date of the Option Term was the date
originally  set forth  herein as the  Expiration  Date,  provided  that the Base
Monthly Rent to be paid by Tenant during the Option Term shall be the greater of
(i) the Base 

                                    Page 27
<PAGE>

Monthly Rent payable on the Commencement Date, or (ii) ninety five percent (95%)
of the Fair Market  Rental,  as  hereinafter  defined,  for the Premises for the
Option  Term.  Anything  contained  herein to the contrary  notwithstanding,  if
Tenant is in monetary or material  non-monetary  default  beyond any  applicable
cure period under any of the terms, covenants or conditions of this Lease either
at the time Tenant  exercises the Option or at any time thereafter  prior to the
commencement date of the Option Term, Landlord shall have, in addition to all of
Landlord's  other  rights and  remedies  provided  in this  Lease,  the right to
terminate the Option upon notice to Tenant,  in which event the expiration  date
of this Lease shall be and remain the  Expiration  Date or the expiration of the
then relevant Option Term. As used herein, the term "Fair Market Rental" for the
Premises  shall mean the rental and all other  monetary  payments  including any
escalations and adjustments thereto (including without limitation Consumer Price
Indexing) then being obtained for leases of space  comparable in age and quality
to the  Premises in the  locality of the  Building  that  Landlord  could obtain
during the Option Term from a third party desiring to lease the Premises for the
Option Term based upon the current use and other potential uses of the Premises.
The appraisers shall be instructed that the foregoing five percent (5%) discount
is intended to reduce comparable rents which include (i) brokerage  commissions,
(ii) tenant improvement allowances,  and (iii) vacancy costs, to account for the
fact that Landlord will not suffer such costs in the event Tenant  exercises its
Option. The Fair Market Rental shall specifically  exclude any additional rental
attributable to the value of the Tenant  Improvements or Alterations paid for by
Tenant.

         B. Determination of Fair Market Rental: If Tenant exercises the Option,
Landlord  shall send to Tenant a notice setting forth the Fair Market Rental for
the Premises for the Option Term within thirty (30) days of Tenant's exercise of
the  Option.  If Tenant  disputes  Landlord's  determination  of the Fair Market
Rental for the Option Term, Tenant shall, within thirty (30) days after the date
of Landlord's  notice  setting forth the Fair Market Rental for the Option Term,
send to Landlord a notice stating that Tenant either (i) elects to terminate its
exercise  of the Option,  in which  event the Option  shall lapse and this Lease
shall  terminate on the  Expiration  Date,  or (ii)  disagrees  with  Landlord's
determination  of Fair  Market  Rental for the Option Term and elects to resolve
the  disagreement  as provided in Article 37.C below. If Tenant does not send to
Landlord a notice as provided in the previous sentence, Landlord's determination
of the Fair Market  Rental shall be the basis for  determining  the Base Monthly
Rent to be paid by Tenant  hereunder during the Option Term. If Tenant elects to
resolve the  disagreement  as provided in Article 37.C below and such procedures
shall not have been concluded prior to the commencement date of the Option Term,
Tenant shall pay as Base Monthly Rent to Landlord the rent due hereunder  during
the month preceding the Expiration  Date. If the amount of Fair Market Rental as
finally  determined  pursuant to Article 37.C below is greater  than  Landlord's
determination,  Tenant shall pay to Landlord the  difference  between the amount
paid by Tenant  and the he rent due  hereunder  during the month  preceding  the
Expiration  Date within  thirty (30) days after the  determination.  If the Fair
Market  Rental  as  finally  determined  in  Article  37.C  below  is less  than
Landlord's  determination,  the difference between the amount paid by Tenant and
the Fair Market Rental as so determined in

                                    Page 28

<PAGE>

Article 37.C below shall be credited  against the next  installments of rent due
from Tenant to Landlord hereunder.

         C.  Resolution  of a  Disagreement  over the Fair  Market  Rental:  Any
disagreement regarding the Fair Market Rental shall be resolved as follows:

                    1.  Within  thirty  (30) days  after  Tenant's  response  to
Landlord's notice to Tenant of the Fair Market Rental, Landlord and Tenant shall
meet no less than two (2) times,  at a  mutually  agreeable  time and place,  to
attempt to resolve any such disagreement.

                    2. If within the thirty  (30) day period  referred to in (i)
above, Landlord and Tenant can not reach agreement as to the Fair Market Rental,
they shall each select one appraiser to determine the Fair Market  Rental.  Each
such  appraiser  shall arrive at a  determination  of the Fair Market Rental and
submit their  conclusions  to Landlord and Tenant  within thirty (30) days after
the  expiration  of the thirty (30) day  consultation  period  described  in (i)
above.

                    3. If only one  appraisal is submitted  within the requisite
time period, it shall be deemed to be the Fair Market Rental. If both appraisals
are submitted  within such time period,  and if the two  appraisals so submitted
differ by less than ten percent  (10%) of the higher of the two,  the average of
the two shall be the Fair Market Rental.  If the two  appraisals  differ by more
than ten percent (10%) of the higher of the two, then the two  appraisers  shall
immediately select a third appraiser who shall within thirty (30) days after his
or her selection shall select one of the two (2) existing determinations of Fair
Market Rental as correct.  This third  appraiser's  conclusion shall be the Fair
Market Rental.

                    4. All appraisers  specified  pursuant to this Article shall
be members of the  American  Institute of Real Estate  Appraisers  with not less
than five (5) years experience  appraising  office and industrial  properties in
the Santa Clara Valley.  Each party shall pay the cost of the appraiser selected
by such party and one-half of the cost of the third appraiser.

     38. Tenant's Right of First Refusal:

         A. Grant.  Landlord  hereby  grants to Tenant a right of first  refusal
during the Term of this Lease and any extension thereof to purchase the Premises
("Right of First Refusal to Purchase").

         B.  Covenants of Landlord.  Landlord  hereby  covenants and agrees with
Tenant that if, during the Term of the Lease,  Landlord shall receive or solicit
a bona fide offer from a  prospective  buyer to  purchase  either the  Premises,
Landlord  shall furnish  Tenant with a copy of the proposed  contract and notify
Tenant of the intention of Landlord to accept the same (the "Notice of Intention
to Sell").  Such Notice of Intention to Sell shall contain all material business
terms on which

                                    Page 29
<PAGE>


Landlord  intends  to sell the  Premises.  Landlord  shall not sell the space in
question  to anyone  other  than  Tenant  without  first  providing  Tenant  the
opportunity  to buy the space in  question  upon the same  terms and  conditions
described in the Notice of Intention to Sell.

         C. Exercise of Tenant's  Right of First  Refusal to Purchase.  Provided
that  Tenant is not in  default  under the terms and  conditions  of this  Lease
beyond any applicable grace periods, Tenant may exercise Tenant's Right of First
Refusal to Purchase by providing  Landlord with written  notice  thereof  within
fifteen (15) days of Tenant's  receipt of the Notice of Landlord's  Intention to
Sell.  If Tenant does not exercise  its Right of First Offer to Purchase  within
said  fifteen (15) day period,  then  Landlord  shall be relieved of  Landlord's
obligation  to offer the space  identified in the Notice of Intention to Sell to
Tenant, except as provided for in Section 38.E below.

         D.  Terms for Right of First  Refusal  to  Purchase.  In the event that
Tenant exercises Tenant's Right of First Refusal to Purchase,  Tenant's purchase
shall be on all of the same terms and  conditions  as are offered to a bona-fide
third-party  purchaser  of the space  identified  in the Notice of  Intention to
Sell.

         E. Continuing Right. In no event shall Tenant's failure to exercise its
Right of First  Refusal  to  Purchase  be deemed a waiver or  relinquishment  by
Tenant of  Tenant's  Right of First  Refusal  to  Purchase  should (i) the space
identified in the Notice of Intention to Sell be offered for sale to a potential
purchaser  other  than the  purchaser  specified  in the  Notice  of  Landlord's
Intention  to Sell during the Term of this Lease or any  extension  thereof,  or
(ii) the space  identified  in the  Notice of  Landlord's  Intention  to Sell be
offered for sale to any purchaser on terms different than those specified in the
Notice of  Landlord's  Intention  to Sell  during  the Term of this Lease or any
extension thereof.

         F.  Exclusive  Nature of Option.  Landlord  represents  and warrants to
Tenant that no party  other than Tenant has any option,  right of first offer or
right of first refusal to purchase the Premises.  Landlord  hereby  covenants to
Tenant that Landlord shall not grant an option to purchase, right of first offer
or right of first refusal to purchase the Premises during the Term of this Lease
or any extension thereof

         G.  Successors and Assigns.  Except as provided in this paragraph 38.G,
this Right of First Refusal to Purchase  shall be binding on the  successors and
assigns  of  Landlord  and  Tenant.  This  Right  of  First  Refusal  shall  not
specifically  not apply to (but shall  survive the same and be binding  upon any
purchaser  or  successor  of such  sale or  foreclosure)  (i)  any  transfer  of
ownership of the Premises by a judicial  foreclosure  sale or sale pursuant to a
power  of  sale  provision  in any  relevant  deed of  trust  or  mortgage  lien
,transfers  of the  Building,  or (ii) a "Sobrato  Family  Transfer".  A Sobrato

and/or John M.  Sobrato  (individually  and  collectively  "Sobrato"),  (ii) any
immediate family member of Sobrato, (iii)

any trust  established,  in whole or in part,  for the benefit of Sobrato and/or
any immediate family member of Sobrato, (iv) any partnership in which Sobrato or
any immediate  family member,  either  directly or indirectly  (e.g.,  through a
partnership or corporate entity or a trust) retains a general partner  interest,
and/or (v) any corporation under the control, either directly or indirectly,  by
Sobrato or any immediate family member of Sobrato.

         39. Options:  Except with respect to any Tenant Affiliate,  all Options
provided  Tenant in this Lease are personal  and granted to original  Tenant and
are not  exercisable  by any third party should Tenant assign or sublet  (except
for any  assignment  permitted by the third to last paragraph of Article 29) all
or a portion of its rights under this Lease,  unless Landlord consents to permit
exercise  of any  option  by any  assignee  or  subtenant,  in  Landlord's  sole
discretion.  In the event that  Tenant  hereunder  has any  multiple  options to
extend this Lease, a later option to extend the Lease cannot be exercised unless
the prior option to extend has been so exercised.

         40.  Quiet  Enjoyment:  Landlord  covenants  with Tenant for itself and
Landlord's  successors that so long as no Event of Default on the part of Tenant
has occurred  hereunder,  (i) Tenant shall and may  peaceably  and quietly have,
hold and enjoy the  Premises  for the Term of this  Lease,  and any  renewals or
extensions thereof;  and (ii) neither Landlord,  nor any party claiming under or
through  Landlord,  shall  disturb the use or the  occupancy  of the Premises by
Tenant.

         41.  Brokers:  Landlord and Tenant each warrants and represents for the
benefit of the other that it has had no dealings  with any real estate broker or
agent in connection with the  negotiation of this Lease,  except for CB Madison,
and that it knows of no other  real  estate  broker  or agent who is or might be
entitled to a real estate  brokerage  commission  or finder's fee in  connection
with this Lease. Each party shall indemnify and hold harmless the other from and
against any and all  liabilities  or expenses  arising out of claims made by any
broker (other than CB Madison) or individual  for  commissions or fees resulting
from the actions of the indemnifying party in connection with this Lease.

         42.  Landlord's  Liability:  If Tenant should  recover a money judgment
against  Landlord  arising in connection with this Lease,  the judgment shall be
satisfied  only  out of  Landlord's  interest  in  the  Premises  including  the
improvements  and real  property  and neither  Landlord or any of its  partners,
officers, directors, agents, trustees, shareholders or employees shall be liable
personally for any deficiency. And furthermore,  Tenant expressly waives any and
all rights to proceed against the individual partners or the officers, directors
or shareholders of any corporate partner, except to the extent of their interest
in said limited partnership.

provide the requesting party with corporate resolutions or other proof in a form
acceptable to the requesting party, authorizing the execution of the Lease.

     44. Transportation  Demand Management Programs:  Should a government agency
or  municipality  require  Landlord  to  institute  TDM  (Transportation  Demand
Management) facilities and/or program, Tenant hereby agrees that the cost of TDM
imposed  facilities  required  on the  Premises,  including  but not  limited to
employee showers, lockers, cafeteria, or lunchroom facilities, shall be included

statute, shall be resolved at the request of any party to this agreement through

          EXHIBIT "B" - Formula for Determination of Base Monthly Rent



After  receipt of the final  pricing  for the  Building  Shell,  Landlord  shall
determine  Total Project  Costs (as defined  below) based on  competitive  bids.
During  this  period  Landlord  shall also  solicit  permanent  loan quotes from
institutional lenders to determine the best available financing.  Based on these
inputs  Landlord  shall then apply the  following  formula to determine the Base
Monthly Rent due under this Lease.

Base Monthly Rent shall be equal to one hundred twenty percent of the product of
the (i) Total Project Costs as defined below and (ii) the best non-participating
ten (10) year fixed rate permanent loan constant available prior to the start of
construction of the Option Building.  The  determination of which loan comprises
the best  available  financing  shall be made in good faith by both Landlord and
Tenant.  The parties  acknowledge  that it is their current  intention that such
amortization  schedule  shall be for a minimum  period of twenty  (20) years and
Landlord shall use its best efforts to obtain such financing.

Total Project Costs shall be equal to the sum of (i) the value of the land based
on a value of Nine and 90/100  Dollars  ($9.90) per land square  foot,  (ii) the
Building Shell Allowance, (iii) fees for building permits, licenses, inspection,
utility  connections or extensions,  and any other fees imposed by  governmental
entities, (iv) fees of engineers,  architects,  consultants and others providing
professional  services in connection with the construction of the Building,  (v)
construction  loan  interest paid by Landlord  including  interest on Landlord's
equity with  respect to the  construction  of the  Building,  calculated  at the
reference  rate  charged by Union  Bank plus one  percent  (1%),  (vi) loan fees
payable for the  construction  and/or permanent loan for the Building (vii) real
property taxes and assessments levied against the Property during the period the
Building is constructed,  (viii) liability and builders risk insurance  premiums
paid by Landlord with respect to the construction of the Building, and (ix) real
estate  leasing  commissions  or fees  payable by Landlord  with  respect to the
Building.

For example,  if Total  Project  Costs are  $6,600,000,  and Landlord is able to
obtain a 7.75% loan with a 20 year amortization,  the Base Monthly Rent would be
120% X ($6,600,000 X .008209), or $65,015.28.

                               KOMAG, INCORPORATED

                            DISCRETIONARY BONUS PLAN


        I.        PURPOSES OF THE PLAN

                  1.01 Komag,  Incorporated (the "Company")  hereby  establishes
this Discretionary Bonus Plan ("Plan") as an incentive program pursuant to which
discretionary  or other  retention-based  bonuses may be awarded for one or more
fiscal years in order to retain the services of those employees  critical to the
Company's financial success.

                  1.02 The  Company's  compensation  programs  are  designed  to
retain and  motivate  technical  and  managerial  staff  through the delivery of
competitive cash  compensation each year. Base pay is targeted at the mid-market
level of the high technology  industry,  and significantly  greater compensation
will be delivered  through the  Company's  variable  pay programs  (such as cash
profit sharing and payments under the Company's  Management  Bonus Plan).  It is
the Company's  objective to provide total cash compensation at or above the 75th
percentile of a competitive analysis. Accordingly, the Compensation Committee of
the  Company's  Board  of  Directors  as  plan  administrator  shall,  with  the
assistance of the Company's management and such outside compensation specialists
as the Compensation Committee may deem appropriate, undertake such a competitive
analysis  for each fiscal year the Plan  remains in effect.  If the analysis for
any fiscal year  suggests that the level of cash  compensation  for that year is
not significantly  greater than the industry average, a cash bonus pool for that
year will be  established  for  distribution  to selected  employees.  The bonus
distribution  will be targeted to those  employees  considered  essential to the
Company's  continued  financial  success who would  otherwise be  vulnerable  to
competitor recruiting by offers of more attractive compensation.

       II.        ADMINISTRATION OF THE PLAN

                  2.01 The Plan is  hereby  adopted  by the  Company's  Board of
Directors (the "Board"),  effective  December 1, 1996, and shall be administered
by the Compensation Committee ("Committee") of the Board.

                  2.02 The  interpretation  and construction of the Plan and the
adoption of rules and  regulations for  administering  the Plan shall be made by
the  Committee.  Decisions  of the  Committee  shall be final and binding on all
parties who have an interest in the Plan.


<PAGE>

      III.        DISCRETIONARY BONUS POOL

                  3.01 The  Committee  shall  make an annual  assessment  of the
industry,  including such factors as the financial  performance of the Company's
competitors,  the  expansion  plans  of  those  competitors,  and a  competitive
analysis of the Company's annual cash compensation. Should such analysis suggest
that the level of annual cash  compensation  for the  Company's key employees is
not competitive, resulting in their vulnerability to recruitment by other firms,
or should industry  trends reveal that recruiting  activity will in the upcoming
year be significant, the Committee shall have full power and authority to create
a bonus pool  under the Plan for that  fiscal  year.  The bonus pool shall be in
such dollar amount as the Committee  deems  appropriate and shall be distributed
to  selected  employees  as an  incentive  for them to remain  in the  Company's
employ.

       IV.        DETERMINATION OF PARTICIPANTS

                  4.01 Those  individuals  in the  employ of the  Company or any
subsidiary who are significant  contributors to the continued and future success
of the Company's  business shall be eligible to receive a distribution  from one
or more of the bonus pools  established over the term of the Plan. The Company's
Chief  Executive  Officer  and the  Chairman  of the  Board  shall  provide  the
Committee with  recommendations  each fiscal year as to the employees who should
receive  bonus  awards  under the Plan for that fiscal year and the amount to be
allocated to each designated employee.  The Committee shall, on the basis of the
competitive   compensation  analysis  undertaken  for  that  fiscal  year,  have
authority  to accept or modify  such  recommendations.  The  Committee  may also
recommend a bonus  distribution  under the Plan to the Company's Chief Executive
Officer and the Chairman of the Board.

        V.        PAYMENT OF BONUS AWARDS

                  5.01 The  individual  bonus awarded to each employee  shall be
paid to such employee  within thirty (30) days after the completion of the audit
of the fiscal year for which that award is made. In no event,  however,  shall a
bonus award be paid to any  individual  who does not  continue in the  Company's
employ  through  such  payment  date.  Any payment to which an employee  becomes
entitled  under  the  Plan  shall  be  made  in  the  form  of a lump  sum  cash
distribution,  subject to the Company's collection of all applicable federal and
state income and employment withholding taxes.

                  5.02 Bonus  payments  under the Plan shall be  included in the
earnings base eligible for deferral under the Company's  non-qualified  Deferred
Compensation Plan.

       VI.        GENERAL PROVISIONS

                  6.01 The Plan is  effective  as of December  1, 1996,  and the
initial bonus pool under the Plan will be  established  for the  Company's  1996
fiscal year.  The Board may at any time amend,  suspend or  terminate  the Plan,
provided  such action is effected by written  resolution  and does not adversely
affect the rights and interests of Plan participants to any bonus awards made to
them  prior  to  such  amendment,   suspension  or   termination.   Neither  the
implementation  of the  Plan  nor  any  amendment  to  the  Plan  shall  require
stockholder approval.

                  6.02 No  bonuses  awarded  under the Plan  shall  actually  be
funded,  set aside or otherwise  segregated prior to payment.  The obligation to
pay the  bonuses  awarded  hereunder  shall  at all  times  be an  unfunded  and
unsecured obligation of the Company.  Plan participants shall have the status of
general creditors and shall look solely to the general assets of the Company for
the payment of their bonus awards.

                  6.03 No Plan  participant  shall  have the right to  alienate,
pledge or  encumber  his/her  interest  in any bonus  award to which  he/she may
become  entitled  under the Plan,  and such  interest  shall not (to the  extent
permitted  by  law)  be  subject  in any  way to the  claims  of the  employee's
creditors or to attachment, execution or other process of law.

                  6.04  Neither  the action of the Company in  establishing  the
Plan, nor any action taken under the Plan by the Committee, nor any provision of
the Plan shall be construed so as to grant any person the right to remain in the
employ of the Company or its subsidiaries  for any period of specific  duration.
Rather,  each  employee  of the  Company  or any  subsidiary  will  be  employed
"at-will,"  which means that either such employee or the Company (or subsidiary)
may terminate the employment relationship of that individual at any time for any
reason, with or without cause.

                                       3.

                              PLAN AMENDMENT NO. 1

                  The  Komag,   Incorporated   Deferred  Compensation  Plan,  as
established effective March 1, 1995 (the "Plan"), is hereby amended as follows:

                  1.       Section 4.01 is hereby amended,  effective January 1,
1997, to read as follows:

                           4.01 Annual Election. Each Participant shall have the
         right to file a  Deferral  Election  to defer  part of the base  salary
         and/or  Bonus  earned for one or more Years of Service  for which he or
         she  remains a  Participant.  However,  the maximum  amount  which such
         Participant  may defer for each Year of Service  shall be determined in
         accordance with the following formula:

                           - up to  twelve  percent  (12%)  of the  base  salary
         earned  for his or her  period  of  participation  during  that Year of
         Service, plus

                           - up to twelve  percent (12%) of any Bonus earned for
         such Year of Service, less

                           - the maximum  dollar amount which may be contributed
         on the Participant's  behalf as a Section 401(k)  Contribution for that
         Year of Service pursuant to the applicable limitations of Code Sections
         401(k) and 402(g).

                  2.       Section  4.03 is hereby  amended,  effective  June 1,
1996, to read as follows:

                           4.03  Commencement of Deferrals.  The actual deferral
         of base salary pursuant to the  Participant's  Deferral  Election shall
         not begin until such time as the maximum  Section  401(k)  Contribution
         permissible  under the Qualified  Plan and Code Section  402(g) for the
         calendar  year in which that base salary is earned shall have been made
         on the  Participant's  behalf to the

<PAGE>

         QualifiedPlan in accordance with his or her Section 401(k) Election for
         that  year or would  have  been made in the  absence  of any  voluntary
         reduction in the  Participant's  Section 401(k) Election for that year.
         The  portion of the Bonus  which is the  subject  of the  Participant's
         Deferral Election shall in fact be deferred under this Plan only if the
         remaining  portion  of that  Bonus is paid  after the  maximum  Section
         401(k)  Contribution  permissible  under  the  Qualified  Plan and Code
         Section  402(g) for the calendar  year of such payment  shall have been
         made on the  Participant's  behalf to the Qualified  Plan in accordance
         with his or her  Section  401(k)  Election  for that year or would have
         been made in the absence of any reduction in the participant's  Section
         401(k)  Election for that year. In the event there is no Section 401(k)
         Election  in effect for the  Participant  at the start of the  calendar
         year to which his or her Deferral  Election  pertains,  then the actual
         deferral of base salary pursuant to that Deferral  Election shall begin
         at such time as the maximum  Section  401(k)  Contribution  permissible
         under the Qualified Plan and Code Section 402(g) for that calendar year
         would have been made on the Participant's  behalf to the Qualified Plan
         had there been in effect for that  individual a Section 401(k) Election
         covering  ten  percent  (10%) or  (effective  January 1,  1997)  twelve
         percent  (12%)  of his or her  eligible  earnings  for the  year,  with
         earnings   to  be   imputed,   solely  for   purposes  of  such  timing
         determination,  to the Participant (based on his or her annualized rate
         of base  salary) for any portion of that year in which such  individual
         was not an  Employee.  The same  principle  shall be in effect  for the
         portion of any Bonus  subject to the  Deferral  Election  filed by such
         Participant.

                  3.       Except as  modified by this Plan  Amendment,  all the
terms and  provisions  of the Plan shall  continue in full force and effect.

         IN WITNESS WHEREOF,  Komag,  Incorporated has caused this instrument to
be executed on its behalf by a duly authorized officer on ____ day of __________
June, 1996.

         shall be treated as a prepayment by Borrower of the Revolving  Loans to
         the extent of such interest so purchased),  and the Commitment shall be
         reduced by such  selling  Participant's  Participation  interest in the
         Commitment  allocated to such  Participant  under the  Participation so
         purchased by Borrower.

                           (d)  Section  2.1 of the Credit  Agreement  is hereby

         Agreement to the contrary  notwithstanding:  (i) unless the maturity of

         7.1 hereof,  the Existing Loan may not be repaid except on December 29,
         1997,  (ii) no Interim Loan which is a Eurodollar Rate Loan may have an
         Interest  Period ending after  December 29, 1997,  unless such Interest
         Period  commences  on December 29,  1997,  and (iii) from  November 29,
         1997, to December 29, 1997,  Interim Loans may be made,  converted,  or

                           (e) Section 8.6(D) of the Credit  Agreement is hereby
amended by inserting  the phrase "or amend or waive the  provisions  of Sections

                                   ARTICLE II

                        AMOUNTS AND TERMS OF THE ADVANCES
                            AND THE LETTERS OF CREDIT

                  SECTION 2.01. The Advances.  The Lender  agrees,  on the terms
and conditions  hereinafter  set forth,  to make advances (each an "Advance") to
the  Borrower  from time to time on any  Business Day during the period from the
date hereof until the Termination Date in an amount for each such Advance not to
exceed the Lender's  Unused  Commitment at such time. Each Borrowing shall be in
an aggregate amount of $1,000,000 or an integral  multiple of $100,000 in excess
thereof. Within the limits of the Lender's Unused Commitment in effect from time
to time, the Borrower may borrow under this Section 2.01(a),  prepay pursuant to
Section 2.05 and reborrow under this Section 2.01(a).

                  SECTION 2.02. Making the Advances. (a) Each Borrowing shall be
made on notice,  given not later than 10:00  A.M.  (San  Francisco  time) on the
third Business Day prior to the date of the proposed Borrowing, in the case of a
Borrowing consisting of a LIBOR Advance, or the Business Day that is the date of
the proposed  Borrowing,  in the case of a Borrowing  consisting  of a Base Rate
Advance or Federal Funds Rate Advance,  by the Borrower to the Lender. Each such
notice of a Borrowing (a "Notice of Borrowing") shall be by telephone, confirmed
immediately in writing,  or telex or telecopier,  in  substantially  the form of
Exhibit B hereto,  specifying  therein the requested (i) date of such Borrowing,
(ii) Type of Advance  comprising such Borrowing,  (iii) amount of the Advance to
comprise  such  Borrowing  and (iv) in the case of a Borrowing  consisting  of a
LIBOR Advance or Federal Funds Rate Advance,  initial LIBOR  Interest  Period or
Federal Funds Interest Period, as the case may be, for such Advance.  The Lender
shall, before 2:00 P.M. (San Francisco time) on the date of such Borrowing, make
available  for the account of its  Applicable  Lending  Office to the  Borrower,
subject to fulfillment  of the  applicable  conditions set forth in Article III,
funds in the amount of the  Advance  made in such  Borrowing  by  crediting  the
Borrower's Account.

                  (b)  Anything  in   subsection   (a)  above  to  the  contrary
notwithstanding,  (i) the  Borrower  may not  select a LIBOR  Advance or Federal
Funds Rate Advance,  as the case may be in an amount of less than  $1,000,000 or
if the  obligation  of the Lender to make LIBOR  Advances or Federal  Funds Rate
Advances,  as the case may be, shall then be suspended  pursuant to Section 2.08
or Section 2.09 and (ii) not more than six Advances  may be  outstanding  at any
time.

                  (c) Each Notice of Borrowing  shall be irrevocable and binding
on the  Borrower.  In the case of any  Borrowing  that  the  related  Notice  of
Borrowing  specifies is to be comprised of a LIBOR Advance or Federal Funds Rate
Advance,  the Borrower  shall 

<PAGE>
                                      12

indemnify the Lender against any loss, cost or expense incurred by the Lender as
a result of any  failure  to fulfill  on or before  the date  specified  in such
Notice of Borrowing for such  Borrowing the  applicable  conditions set forth in
Article III, including,  without limitation,  any loss, cost or expense incurred
by reason of the liquidation or reemployment of deposits or other funds acquired
by the Lender to fund the  Advance  to be made by the  Lender in such  Borrowing
when such Advance, as a result of such failure, is not made on such date.

                  SECTION 2.03. Repayment of Advances.  The Borrower shall repay
to the Lender on the Termination Date the aggregate outstanding principal amount
of the Advances then outstanding.

                  SECTION 2.04. Termination or Reduction of the Commitments. The
Borrower may, upon at least five Business Days' notice to the Lender,  terminate
in whole or reduce in part the Unused Commitment;  provided,  however, that each
such partial  reduction  shall be in an  aggregate  amount of  $1,000,000  or an
integral multiple of $100,000 in excess thereof.

                  SECTION 2.05. Prepayments. The Borrower may, upon at least one
Business  Day's notice in the case of Base Rate  Advances or Federal  Funds Rate
Advances and three Business Days' notice in the case of LIBOR Advances,  in each
case to the Lender stating the proposed date and aggregate  principal  amount of
the  prepayment,  and if such  notice is given the  Borrower  shall,  prepay the
outstanding  aggregate  principal  amount  of an  Advance  in  whole or in part,
together  with  (i)  accrued  interest  to the  date of such  prepayment  on the
aggregate  principal amount prepaid;  provided,  however,  that (x) each partial
prepayment  shall  be in an  aggregate  principal  amount  of  $1,000,000  or an
integral  multiple of $100,000 in excess  thereof and (y) if any prepayment of a
LIBOR  Advance  or Federal  Funds Rate  Advance is made on a date other than the
last day of an Interest  Period for such Advance the Borrower shall also pay any
amounts owing pursuant to Section 7.04(b).

                  SECTION 2.06. Interest.  (a) Scheduled Interest.  The Borrower
shall pay interest on the unpaid  principal  amount of each Advance owing to the
Lender from the date of such Advance until such  principal  amount shall be paid
in full, at the following rates per annum:

                  (i) Base Rate Advances. During such periods as such Advance is
         a Base Rate  Advance,  a rate per annum  equal at all times to the Base
         Rate in effect  from time to time,  payable in  arrears  monthly on the
         first day of each month  during such  periods and on the date such Base
         Rate Advance shall be Converted or paid in full.

                  (ii) LIBOR Advances.  During such periods as such Advance is a
         LIBOR  Advance,  a rate per annum equal at all times  during each LIBOR
         Interest  Period  for such  Advance to the sum of (A) the LIBO Rate for
         such  Interest  Period for such  Advance  plus (B)  0.375%,  payable in
         arrears on the last day of such  Interest  Period and, if such Interest
         Period  has a  duration  of more than  three  months,  on each day
<PAGE>
                                       13

         that occurs  during such  Interest  Period  every three months from the
         first day of such  Interest  Period and on the date such LIBOR  Advance
         shall be Converted or paid in full.

                  (iii) Federal Funds Rate Advances. During such periods as such
         Advance is a Federal Funds Rate Advance,  a rate per annum equal at all
         times during each Federal Funds Interest Period for such Advance to the
         sum of (A) the Federal  Funds  Advance Rate in effect from time to time
         during such Interest Period plus (B) 0.375%,  payable in arrears on the
         last day of such  Interest  Period and, if such  Interest  Period has a
         duration of more than three months, on each day that occurs during such
         Interest  Period every three months from the first day of such Interest
         Period  and on the  date  such  Federal  Funds  Rate  Advance  shall be
         Converted or paid in full.

                  (b) Default Interest.  To the fullest extent permitted by law,
the Borrower shall pay interest on the amount of any principal, interest, fee or
other amount  payable  hereunder  that is not paid when due,  from the date such
amount shall be due until such amount shall be paid in full,  payable in arrears
on the date such amount shall be paid in full and on demand, at a rate per annum
equal at all times to 2% per annum above the rate per annum required to be paid,
in the case of principal or interest,  on the Type of Advance  comprised of such
principal  or on which such  interest  has accrued  pursuant  to clause  (a)(i),
(a)(ii) or  (a)(iii)  above,  and,  in all other  cases,  on Base Rate  Advances
pursuant to clause (a)(i) above.

                  SECTION 2.07.  Fees.  (a) Facility Fee. The Borrower shall pay
to the Lender a facility  fee,  payable  quarterly on the first  Business Day of
each December,  March, June and September,  commencing  December 1, 1996, and on
the Termination  Date,  accruing from the date hereof until the Termination Date
at the rate of 0.1875% per annum on the amount of the Lender's  Commitment as in
effect on such due date for payment.

                  (b) Upfront Fee.  The Borrower  agrees to pay to the Lender an
upfront fee in the amount  $35,000  (being 0.10% of the  Commitment  on the date
hereof), payable upon execution of this Agreement.

                  (c) Administration  Fee. The Borrower agrees to pay the Lender
an  administration  fee of $1000 per annum,  payable  in  advance in  semiannual
installments  of $500 each,  with the first such  installment  to be paid on the
date of execution of this Agreement and each  subsequent  installment to be paid
on the last day of each six month period after the date of this Agreement  until
such time as all obligations  under the Credit  Agreement have been paid in full
and the Commitment terminated.

                  SECTION  2.08.  Conversion  of  Advances.  (a)  Optional.  The
Borrower may on any Business Day, upon notice given to the Lender not later than
10:00 A.M. (San  Francisco  time) on the third Business Day prior to the date of
the proposed Conversion and subject to the provisions of Sections 2.06 and 2.09,
Convert an Advance of one Type into an

<PAGE>
                                       14

Advance of another Type; provided,  however,  that (i) any Conversion of a LIBOR
Advance  into a Base  Rate  Advance  or  Federal  Funds  Rate  Advance,  and any
Conversion  of a Federal  Funds Rate  Advance  into a Base Rate Advance or LIBOR
Advance, shall be made only on the last day of an Interest Period for such LIBOR
Advance or Federal Funds Rate Advance,  as the case may be, (ii) any  Conversion
of an Advance into a LIBOR  Advance or Federal Funds Rate Advance shall be in an
amount not less than the minimum amount  specified in Section  2.02(b) and (iii)
no Conversion of any Advance  shall result in more  Advances  being  outstanding
than  permitted  under Section  2.02(b).  Each such notice of Conversion  shall,
within  the  restrictions   specified  above,  specify  (x)  the  date  of  such
Conversion, (y) the Advance to be Converted and (z) if such Conversion is into a
LIBOR  Advance or Federal  Funds  Rate  Advance,  the  duration  of the  initial
Interest Period for such Advance. Each notice of Conversion shall be irrevocable
and binding on the Borrower.

                  (b) Mandatory.  (i) On the date on which the aggregate  unpaid
principal amount of any LIBOR Advance or Federal Funds Rate Advance, as the case
may be, shall be reduced,  by payment or prepayment  or otherwise,  to less than
$1,000,000, such Advance shall automatically Convert into a Base Rate Advance.

                  (ii) If the Borrower  shall fail to select the duration of any
Interest Period for any LIBOR Advance or Federal Funds Rate Advance, as the case
may be, in accordance with the provisions  contained in the definition of "LIBOR
Interest  Period" or "Federal  Funds  Interest  Period",  as the case may be, in
Section 1.01, the Lender will  forthwith so notify the Borrower,  whereupon each
such LIBOR  Advance or Federal  Funds  Rate  Advance,  as the case may be,  will
automatically,  on the last day of the then existing  Interest Period  therefor,
Convert into a Base Rate Advance.

                  (iii) Upon the  occurrence  and during the  continuance of any
Event of Default,  (x) each LIBOR  Advance and each  Federal  Funds Rate Advance
will  automatically,  on the  last  day of the  then  existing  Interest  Period
therefor,  Convert into a Base Rate Advance and (y) the obligation of the Lender
to make,  or to Convert  Advances  into,  LIBOR  Advances or Federal  Funds Rate
Advances shall be suspended.

                  SECTION 2.09.  Increased Costs, Etc. (a) If, due to either (i)
the  introduction of or any change in, or in any written  interpretation  by any
central bank or other governmental  authority of competent  jurisdiction of, any
law or regulation or (ii) the compliance  with any guideline or request from any
central bank or other governmental authority (whether or not having the force of
law),  there shall be any increase in the cost to the Lender of agreeing to make
or of making,  funding or maintaining LIBOR Advances  (excluding for purposes of
this Section 2.09 any such increased  costs  resulting from (i) taxes covered by
the gross-up and indemnification  provisions of Section 2.11 and (ii) changes in
the basis of  taxation  of overall  net income or  overall  gross  income by the
United  States or by the foreign  jurisdiction  or state under the laws of which
the Lender is organized or has its  Applicable  Lending  Office or any political
subdivision thereof),  then the Borrower shall from time to time, upon demand by
the Lender,  pay to the Lender additional  amounts  sufficient to compensate the
Lender for such increased cost; provided, however, that if the Lender should

<PAGE>
                                       15

claim  additional  amounts  under this Section  2.09(a) the Lender agrees to use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different  Applicable  Lending Office if the making
of such a  designation  would  avoid the need for, or reduce the amount of, such
increased  cost that may  thereafter  accrue  and would not,  in the  reasonable
judgment  of  the  Lender,  be  otherwise   disadvantageous  to  the  Lender.  A
certificate  as to the  amount of such  increased  cost set forth in  reasonable
detail,  submitted to the Borrower by the Lender,  shall be presumptive evidence
of such increased cost.

                  (b) If,  due to either (i) the  introduction  of or any change
in, or in any written  interpretation by any central bank or other  governmental
authority  of  competent  jurisdiction  of,  any law or  regulation  or (ii) the
compliance  with  any  guideline  or  request  from  any  central  bank or other
governmental  authority (whether or not having the force of law), there shall be
any increase in the amount of capital  required or expected to be  maintained by
the Lender as a result of or based upon the existence of the Lender's commitment
to lend hereunder and other  commitments of such type,  then, upon demand by the
Lender, the Borrower shall pay to the Lender,  from time to time as specified by
the Lender,  additional amounts sufficient to compensate the Lender in the light
of such circumstances,  to the extent that such increase in capital is allocable
to the existence of the Lender's commitment to lend hereunder.  A certificate as
to such amounts  submitted  to the  Borrower by the Lender shall be  presumptive
evidence of such increased cost.

                  (c) If,  with  respect to any LIBOR  Advance or Federal  Funds
Rate  Advance  the Lender  reasonably  determines  that the LIBO Rate or Federal
Funds  Interest  Rate,  as the case may be,  for any  Interest  Period  for such
Advance will not adequately reflect the cost to the Lender of making, funding or
maintaining  such LIBOR Advance or Federal  Funds Rate Advance,  as the case may
be, for such Interest Period, the Lender shall forthwith so notify the Borrower,
whereupon (i) such LIBOR Advance or Federal Funds Rate Advance,  as the case may
be, will  automatically,  on the last day of the then existing  Interest  Period
therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lender
to make,  or to Convert  Advances  into,  LIBOR  Advances or Federal  Funds Rate
Advances,  as the case may be, shall be suspended  until the Lender shall notify
the  Borrower  that  it has  determined  that  the  circumstances  causing  such
suspension no longer exist.

                  (d) Notwithstanding any other provision of this Agreement,  if
the  introduction of or any change in, or in any written  interpretation  by any
central bank or other governmental  authority of competent  jurisdiction of, any
law or  regulation  shall  make  it  unlawful,  or any  central  bank  or  other
governmental  authority shall assert that it is unlawful,  for the Lender or its
LIBOR Lending Office to perform its obligations hereunder to make LIBOR Advances
or to continue to fund or maintain  LIBOR  Advances  hereunder,  then, on notice
thereof  and  demand  therefor  by the  Lender to the  Borrower,  (i) each LIBOR
Advance will automatically,  upon such demand,  Convert into a Base Rate Advance
and (ii) the  obligation  of the Lender to make,  or to Convert  Advances  into,
LIBOR  Advances  shall be  suspended  until the Lender shall notify the Borrower
that it has determined that the circumstances  causing such suspension no longer
exist; provided, however, that, before making any such demand, the Lender agrees
to use reasonable  efforts  (consistent  with its 

<PAGE>
                                       16

internal policy and legal and regulatory  restrictions) to designate a different
LIBOR Lending Office if the making of such a designation  would allow the Lender
or its LIBOR Lending Office to continue to perform its obligations to make LIBOR
Advances or to continue to fund or maintain LIBOR Advances and would not, in the
reasonable judgment of the Lender, be otherwise significantly disadvantageous to
the Lender.

                  SECTION  2.10.  Payments  and  Computations.  (a) The Borrower
shall make each payment hereunder and under the Note,  irrespective of any right
of  counterclaim  or set-off,  not later than 11:00 A.M. (San Francisco time) on
the day when due in U.S.  dollars to the Lender at the Lender's  Account in same
day funds,  which shall be applied for the  account of the  Lender's  Applicable
Lending Office.

                  (b) The Borrower hereby  authorizes the Lender,  if and to the
extent  payment  owed to the Lender is not made when due  hereunder or under the
Note, to charge from time to time against any or all of the Borrower's  accounts
with the Lender any amount so due.  The  Lender  agrees  promptly  to notify the
Borrower after any such charge to the Borrower's  accounts;  provided,  however,
that the  failure to give such  notice  shall not affect  the  validity  of such
charge.

                  (c) All  computations  of  interest  based on the Base Rate or
Federal  Funds Rate shall be made by the Lender on the basis of a year of 365 or
366 days, as the case may be, and all computations of interest based on the LIBO
Rate and of fees shall be made by the Lender on the basis of a year of 360 days,
in each  case  for the  actual  number  of days  (including  the  first  day but
excluding the last day) occurring in the period, if any, for which such interest
or fees are  payable.  Each  determination  by the  Lender of an  interest  rate
hereunder  or fee  payable  under  Section  2.07,  as the case may be,  shall be
conclusive and binding for all purposes, absent manifest error.

                  (d) Whenever any payment  hereunder or under the Note shall be
stated to be due on a day other than a Business  Day, such payment shall be made
on the next  succeeding  Business Day, and such  extension of time shall in such
case be included in the  computation of payment of interest or accruing fees, as
the case may be; provided,  however, that, if such extension would cause payment
of interest on or principal of any LIBOR  Advance or Federal  Funds Rate Advance
to be made in the next following  calendar month,  such payment shall be made on
the next preceding Business Day.

                  SECTION 2.11.  Taxes. (a) Any and all payments by the Borrower
hereunder  shall be made, in accordance with Section 2.10, free and clear of and
without deduction for any and all future (after the date hereof) taxes,  levies,
imposts or withholdings, and all liabilities with respect thereto, excluding net
income  taxes that are  imposed on the Lender by the United  States or any other
governmental entity (all such non-excluded taxes, levies, imposts,  withholdings
and liabilities in respect of payments  hereunder being referred to as "Taxes").
If the Borrower  shall be required by law to deduct any Taxes from or in respect
of any sum  payable  hereunder  to the  Lender,  (i) the sum  payable  shall  be
increased  as may be  necessary  so that after  making all  required  deductions
(including deductions

<PAGE>
                                       17

applicable  to  additional  sums  payable  under this  Section  2.11) the Lender
receives  an  amount  equal  to the  sum it  would  have  received  had no  such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant  taxation  authority
or other authority in accordance with applicable law.

                  (b) In addition,  the Borrower shall pay any present or future
stamp,  documentary,  excise,  property  or  similar  taxes  that arise from any
payment  made  hereunder or from the  execution,  delivery or  registration  of,
performing  under, or otherwise with respect to, this Agreement or the Note (all
such non-excluded taxes being referred to as "Other Taxes").

                  (c) The  Borrower  shall  indemnify  the  Lender  for the full
amount of Taxes and Other Taxes, and for the full amount of taxes imposed by any
jurisdiction on amounts  payable under this Section 2.11,  imposed on or paid by
the Lender and any liability  (including  penalties,  additions to tax, interest
and expenses)  arising therefrom or with respect thereto.  This  indemnification
shall be made  within  30 days from the date the  Lender  makes  written  demand
therefor accompanied by a reasonably detailed explanation thereof.

                  (d) Within 30 days after the date of any payment of Taxes, the
Borrower  shall  furnish to the Lender,  at its  address  referred to in Section
7.02,  the  original  receipt of payment  thereof  or a  certified  copy of such
receipt, unless such payment has been made to or through the Lender. In the case
of any payment  hereunder by or on behalf of the Borrower  through an account or
branch  outside the United  States or by or on behalf of the Borrower by a payor
that is not a United States person, if the Borrower determines that no Taxes are
payable  in  respect  thereof,  the  Borrower  shall  furnish  to the  Lender  a
certificate of the Borrower  certifying  that such payment is exempt from Taxes.
For  purposes of this  subsection  (d) and  subsection  (e),  the terms  "United
States" and "United States person" shall have the meanings  specified in Section
7701 of the Internal Revenue Code.

                  (e) The Lender shall, on or prior to the date of its execution
and delivery of this Agreement, and from time to time thereafter as requested in
writing by the  Borrower  (but only so long  thereafter  as the  Lender  remains
lawfully able to do so), provide the Borrower with two original Internal Revenue
Service  forms 1001 or 4224,  as  appropriate,  or any  successor  or other form
prescribed by the Internal Revenue Service, certifying that the Lender is exempt
from or entitled to a reduced rate of United States  withholding tax on payments
pursuant to this  Agreement or the Note. If the forms  provided by the Lender at
the time the Lender first  becomes a party to this  Agreement  indicate a United
States interest withholding tax rate in excess of zero,  withholding tax at such
rate  shall be  considered  excluded  from  Taxes  unless  and until the  Lender
provides the appropriate  form certifying that a lesser rate applies,  whereupon
withholding tax at such lesser rate only shall be considered excluded from Taxes
for periods  governed by such form. If any form or document  referred to in this
subsection (e) requires the disclosure of  information,  other than  information
necessary to compute the tax payable and information required on the date hereof
by  Internal  Revenue  Service  form 1001 or 4224,  that the  Lender  reasonably
considers  to be

                                       18

confidential, the Lender shall give notice thereof to the Borrower and shall not
be obligated to include in such form or document such confidential information.

                  (f) For any period with respect to which the Lender has failed
to provide the Borrower with the  appropriate  form  described in subsection (e)
(other than if such failure is due to a change in law  occurring  after the date
on which a form originally was required to be provided or if such form otherwise
is not  required  under  subsection  (e)),  the Lender  shall not be entitled to
indemnification under subsection (a) or (c) with respect to Taxes imposed by the
United  States by reason of such  failure;  provided,  however,  that should the
Lender become subject to Taxes because of its failure to deliver a form required
hereunder,  the Borrower  shall take such steps as the Lender  shall  reasonably
request to assist the Lender to recover such Taxes.

                  (g) Without  prejudice to the survival of any other  agreement
hereunder,  the agreements and obligations of the Borrower  contained in Section
2.09 and this  Section  2.11 shall  survive  the  payment in full of  principal,
interest and all other amounts payable hereunder;  provided,  however,  that the
Borrower's obligation in respect of any claim under Section 2.09 or this Section
2.11  shall  terminate  on the  earlier  to occur of (i) the 180th day after the
expiration of all applicable periods under statutes of limitations applicable to
the matters  underlying  such claims and (ii) the 180th day after any officer of
the Lender having principal  responsibility  for administering this Agreement on
behalf of the Lender  has  actual  knowledge  of the facts  giving  rise to such
claim. The word "hereunder" as used in this Section 2.11 also includes under the
Note.

                  SECTION  2.12.  Use of Proceeds.  The proceeds of the Advances
shall be available  solely to provide  working  capital for the Borrower and for
general corporate purposes of the Borrower.

                  SECTION  2.13.  Extension of Scheduled  Termination  Date.  At
least  45 but  not  more  than 75  days  prior  to the  then  current  Scheduled
Termination  Date, the Borrower,  by written  notice to the Lender,  may request
that the Scheduled Termination Date be extended one calendar year from such then
current  Scheduled  Termination  Date. The Lender shall in turn,  within 30 days
after receipt of such  extension  request  notice from the Borrower,  notify the
Borrower in writing regarding whether the Lender will consent to such extension.
If, and only if, the Lender  consents in writing to such extension  prior to the
30th day after its receipt of such  extension  request notice from the Borrower,
the Scheduled  Termination  Date shall be so extended for such one calendar year
and references  herein to the "Scheduled  Termination  Date" shall refer to such
"Scheduled  Termination  Date" as so extended.  It is understood that the Lender
shall not have any  obligation  whatsoever  to agree to any request  made by the
Borrower for an extension of the Scheduled Termination Date.

         any contractual  provision  binding on or affecting the Borrower or any
         of its Consolidated Subsidiaries and (ii) do not and will not result in
         or require the creation or imposition of any Lien upon or in respect of

         Subsidiaries.  . (c) No  authorization  or approval or other action by,
         and no notice to or filing with, any governmental authority, regulatory

         of such  statements as at June 30, 1996, to customary  fiscal  year-end
         adjustments),  all in accordance  with  generally  accepted  accounting
         principles  consistently  applied,  and since June 30, 1996,  there has

         threatened  action,  suit,  investigation,   litigation  or  proceeding

         credit for the purpose of purchasing  or carrying  margin stock (within
         the meaning of  Regulation  U issued by the Board of  Governors  of the
         Federal Reserve  System),  and no proceeds of the Advances will be used

         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or has been terminated, within the meaning of
         Title  IV of  ERISA,  and no  such  Multiemployer  Plan  is  reasonably
         expected  to be in  reorganization  or to  be  terminated,  within  the
         meaning of Title IV of ERISA.

                  (m) Except as set forth in the financial  statements  referred

         form the basis of an  Environmental  Action against the Borrower or any
         of its Consolidated  Subsidiaries or any of their properties that would
         reasonably be expected to have a Material Adverse Effect.

                  (o)  Neither  the  Borrower   nor  any  of  its   Consolidated
         Subsidiaries is undertaking, and has not completed, either individually
         or together with other potentially responsible parties, any remedial or
         response action relating to any actual or threatened release, discharge
         or disposal of Hazardous  Materials at any site, location or operation,
         either  voluntarily  or  pursuant to the order of any  governmental  or

         reasonably be expected to result in a Material Adverse Effect.

         Influenced  and Corrupt  Organizations  Chapter of the Organized  Crime
         Control  Act of 1970,  except  for  such  noncompliance  as  would  not

         assessments and governmental  charges or levies imposed upon it or upon
         its  property  and (ii) all lawful  claims  that,  if unpaid,  would be

         shall be required to pay or discharge any such tax, assessment,  charge

         proceedings and as to which appropriate  reserves are being maintained,
         unless and until any Lien resulting therefrom attaches to its property,
         becomes  enforceable  against its other creditors and secures an amount

         its   properties,   in  accordance   with  the   requirements   of  all
         Environmental  Laws  except,  in each case,  where the failure to do so
         would not  reasonably  be  expected  to result  in a  Material  Adverse
         Effect;  provided,  however,  that  neither the 
<PAGE>

         Borrower nor any of its Consolidated  Subsidiaries shall be required to
         undertake  any such cleanup,  removal,  remedial or other action to the
         extent that its  obligation  to do so is being  contested in good faith

         permits, licenses, approvals,  privileges and franchises except, in the
         case of any Consolidated  Subsidiary,  where failure to do so would not

         exceeds $15 million; or

                  (i) the  Borrower  or any  ERISA  Affiliate  shall  have  been
         notified by the sponsor of a  Multiemployer  Plan that it has  incurred
         Withdrawal Liability to such Multiemployer Plan in an amount that, when
         aggregated with all other amounts  required to be paid to Multiemployer
         Plans by the Borrower and the ERISA Affiliates as Withdrawal  Liability
         (determined as of the date of such  notification),  exceeds $15 million
         or requires per annum payments exceeding $15 million; or

                  (j) the  Borrower  or any  ERISA  Affiliate  shall  have  been
         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or is being terminated, within the meaning of
         Title  IV  of  ERISA,  and  as  a  result  of  such  reorganization  or
         termination the aggregate annual  contributions of the Borrower and the
         ERISA  Affiliates  to  all   Multiemployer   Plans  that  are  then  in
         reorganization  or being terminated have been or will be increased over
         the amounts  contributed to such Multiemployer Plans for the plan years
         of such  Multiemployer  Plans  immediately  preceding  the plan year in
         which such  reorganization or termination occurs by an amount exceeding
         $15 million;

then,  and in any such  event,  the Lender (i) may,  by notice to the  Borrower,
declare any  obligation  to make Advances to be  terminated,  whereupon the same
shall forthwith terminate, and (ii) may, by notice to the Borrower,  declare the
Advances  and the Note,  all  interest  thereon  and all other  amounts  payable
thereunder and under this  Agreement to be forthwith due and payable,  whereupon
the Advances and the Note,  all such  interest and all such amounts shall become
and be  forthwith  due and  payable,  without  presentment,  demand,  protest or
further  notice of any kind,  all of which are  hereby  expressly  waived by the
Borrower;  provided,  however, that in the event of an actual or deemed entry of
an order for relief with  respect to the Borrower  under the Federal  Bankruptcy
Code (11 U.S.C.  ss.ss.  101 et seq.,  as amended,  or its  successor),  (A) any
obligation of the Lender to make any Advance shall  automatically  be terminated
and (B) the Advances and the Note,  all such interest and all such amounts shall
automatically  become  and be due  and  payable,  without  presentment,  demand,
protest or any notice of any kind, all of which are hereby  expressly  waived by
the Borrower.

                  SECTION 7.04. Costs,  Expenses. (a) The Borrower agrees to pay

pay the fees or expenses of any counsel  retained by any  assignee of the Lender
hereunder.

                  (b) If any  payment of  principal  of, or  Conversion  of, any
LIBOR  Advance or Federal  Funds Rate  Advance is made by the Borrower to or for
the account of the Lender other than on the last day of the Interest  Period for
such  Advance,  as a result of a  payment  or  Conversion  pursuant  to  Section
2.08(b)(i)  or 2.09(d),  acceleration  of the  maturity of the Note  pursuant to
Section 6.01 or for any other  reason,  the Borrower  shall,  upon demand by the
Lender (accompanied with a written statement explaining in reasonable detail the
basis of the demand),  pay to the Lender any amounts  required to compensate the
Lender for any additional losses, costs or expenses that it reasonably incurs as
a result of such  payment,  including,  without  limitation,  any loss,  cost or
expense  incurred by reason of the  liquidation or  reemployment  of deposits or
other  funds  acquired by the Lender to fund or  maintain  such  Advance but not
including loss of anticipated profits.

                  SECTION 7.05.  Right of Set-off.  Upon (a) the  occurrence and
during the  continuance  of any Event of Default and (b) the  declaration of the
Note due and payable  pursuant to the  provisions of Section 6.01, the Lender is
hereby  authorized  at any time and from  time to time,  to the  fullest  extent
permitted by law, to set off and otherwise  apply any and all deposits  (general
or  special,  time or demand,  provisional  or final) at any time held and other
indebtedness at any time owing by the Lender to or for the credit or the account
of the Borrower  against any and all of the  obligations  of the Borrower now or
hereafter  existing under this Agreement and the Note,  irrespective  of whether
the Lender  shall have made any demand  under this  Agreement  or the Note.  The
Lender  agrees  promptly  to notify  the  Borrower  after any such  set-off  and
application;  provided,  however, that the failure to give such notice shall not
affect the  validity of such set-off and  application.  The rights of the Lender
under this  Section  are in addition to other  rights and  remedies  (including,
without limitation, other rights of set-off) that the Lender may have.

                  SECTION 7.06.  Binding  Effect.  This  Agreement  shall become
effective  when it shall have been  executed by the  Borrower and the Lender and
thereafter  shall be binding  upon and inure to the benefit of the  Borrower and
the Lender and their respective successors and assigns, except that the Borrower
shall not have the right to assign its rights  hereunder or any interest  herein
without the prior written consent of the Lender.

                  SECTION 7.07.  Assignments and  Participation.  (a) The Lender
may assign to one or more Persons all or a portion of its rights and obligations
under this Agreement  (including,  without  limitation,  all or a portion of its
Commitment,  the  Advances  owing  to it and the  Note  held  by it);  provided,
however,  that (i) each  such  assignment  (other  than to an  Affiliate  of the
Lender) shall be made only with the written approval of the Borrower and (ii) no
such assignment shall result in the Lender holding a combination of Advances and
Unused  Commitment  in an  aggregate  amount of less  than 51% of the  aggregate
amount of the Advances and Unused Commitment.

(other than (x) the Borrower or any of its Affiliates or (y) any Person that is,
or has Affiliates that are,  engaged in any line of business in competition with
the Borrower or any of the  Borrower's  Affiliates) in or to all or a portion of
its rights and obligations under this Agreement (including,  without limitation,
all or a portion of its  Commitment,  the Advances owing to it and the Note held

Agreement   (including,   without  limitation,   its  Commitment)  shall  remain
unchanged,  (ii) the Lender shall remain solely  responsible to the Borrower for
the performance of such obligations, (iii) the Lender shall remain the holder of
its Note for all purposes of this Agreement, (iv) the Borrower shall continue to
deal solely and directly with the Lender in connection  with the Lender's rights
and  obligations  under this  Agreement  and (v) no  participant  under any such
participation  shall have any right to approve  any  amendment  or waiver of any
provision of any Loan Document,  or any consent to any departure by the Borrower
therefrom,  except to the extent that such  amendment,  waiver or consent  would
reduce the  principal  of, or interest  on, the Note or any fees  payable to the
Lender or other amounts payable hereunder, in each case to the extent subject to
such participation,  postpone any date fixed for any payment of principal of, or
interest on, the Note or any fees or other amounts  payable  hereunder,  in each
case to the extent subject to such participation.

                  (c) The Lender  may,  in  connection  with any  assignment  or
participation or proposed  assignment or participation  pursuant to this Section
7.07,   disclose  to  the  assignee  or  participant  or  proposed  assignee  or
participant, any information relating to the Borrower furnished to the Lender by
or on  behalf  of the  Borrower;  provided,  however,  that,  prior  to any such
disclosure,  the assignee or  participant  or proposed  assignee or  participant
shall agree to preserve  the  confidentiality  of any  confidential  information
received by it from the Lender on the terms provided for in the  Confidentiality
Agreement.

                  (d)  Notwithstanding  any  other  provision  set forth in this
Agreement,  the Lender may at any time assign any of its rights and  obligations
under this  Agreement to any of its  Affiliates  without notice to or consent of
the Borrower; and the Lender or its Affiliates may at any time create a security
interest in all or any portion of its rights  under this  Agreement  (including,
without  limitation,  the Advances owing to it and the Note held by it) in favor
of any Federal  Reserve  Bank in  accordance  with  Regulation A of the Board of
Governors  of the Federal  Reserve  System  without  notice to or consent of the
Borrower.

                  SECTION 7.08. 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.  Delivery of an  executed  counterpart  of a  signature  page to this
Agreement by  telecopier  shall be effective as delivery of a manually  executed
counterpart of this Agreement.

                  SECTION 7.09. Confidentiality. Concurrently with its execution
and  delivery  of  this  Agreement,  the  Lender  will  execute  and  deliver  a
Confidentiality Agreement to the Borrower.

                  FOR VALUE RECEIVED, the undersigned,  Komag,  Incorporated,  a
Delaware  corporation (the  "Borrower"),  HEREBY PROMISES TO PAY to the order of
The  Dai-Ichi  Kangyo  Bank,  Limited  (the  "Lender"),  acting  through its San
Francisco Agency for the account of its Applicable Lending Office (as defined in
the Credit  Agreement  referred to below) the aggregate  principal amount of the
Advances (as defined below) owing to the Lender by the Borrower  pursuant to the
Credit  Agreement  dated as of  October  7, 1996 (as  amended,  supplemented  or
otherwise  modified  from time to time,  the "Credit  Agreement";  terms defined
therein  being used  herein as therein  defined)  between the  Borrower  and the
Lender, on the Termination Date.

                  The Borrower  promises to pay interest on the unpaid principal
amount of each Advance from the date of such Advance until such principal amount
is paid in full,  at such  interest  rates,  and payable at such  times,  as are
specified in the Credit Agreement.

                  Both principal and interest are payable in lawful money of the
United  States of America to the Lender at the  Lender's  Account (as defined in
the Credit  Agreement),  in same day funds.  Each Advance owing to the Lender by
the  Borrower  and the maturity  thereof,  and all  payments  made on account of
principal  thereof,  shall be recorded by the Lender and,  prior to any transfer
hereof,  endorsed on the grid attached hereto,  which is part of this Promissory

entitled to the benefits of, the Credit Agreement.  The Credit Agreement,  among
other things,  (i) provides for the making of advances (the  "Advances")  by the
Lender to the Borrower from time to time in an aggregate amount not to exceed at
any  time  outstanding  the  U.S.  dollar  amount  first  above  mentioned,  the
indebtedness of the Borrower resulting from each such Advance being evidenced by
this  Promissory  Note,  and (ii) contains  provisions for  acceleration  of the
maturity  hereof  upon the  happening  of  certain  stated  events  and also for
prepayments on

the Credit  Agreement is amended to refer to all Banks  executing this Amendment
and all of the duties and  obligations  of the Borrower under the Loan Documents
in  existence  prior to the  date  hereof  shall  be  deemed  to be  duties  and
obligations to the Agent and the Banks executing this Amendment.

                         (d) In Section 1.01 of the Credit Agreement,  the prior
definition of "FICAL", now "Wells Fargo", shall be realphabetized.

                         (e) Section 6.02(f) to the Credit  Agreement is amended

                  4. Miscellaneous.

                         (a) All references to Loan Documents shall refer to the

incorporated into, and a part of, the Loan Documents.

                         (b) This  Amendment  shall be binding upon and inure to
the benefit of the parties  hereto and thereto and their  respective  successors

                         (d) This  Amendment  may be  executed  in any number of
counterparts,  each  of  which  shall  be  deemed  an  original,  but  all  such
counterparts together shall constitute but one and the same instrument.  Each of
the parties  hereto  understands  and agrees that this  Amendment (and any other
document  required  herein) may be delivered by any party thereto  either in the
form  of an  executed  original  or  an  executed  original  sent  by  facsimile
transmission  to be followed  promptly by mailing of a hard copy  original,  and
that  receipt  by the  Agent of a  facsimile  transmitted  document  purportedly
bearing the  signature  of the Borrower or any Bank will have the same force and
effect as the  delivery  of a hard copy  original.  Any  failure by the Agent to
receive the hard copy executed  original of such document shall not diminish the
binding effect of receipt of the facsimile transmitted executed original of such
document of the party whose hard copy page was not received by the Agent.

                         (e) This  Amendment  contains the entire and  exclusive
agreement of the parties hereto with reference to the matters  discussed  herein
and therein.  This Amendment supersedes all prior drafts and communications with
respect thereto. This Amendment may not be amended except in accordance with the
provisions of the Credit Agreement.

                         (f) If any term or provision of this Amendment shall be
deemed  prohibited by or invalid under any applicable  law, such provision shall
be invalidated  without affecting the remaining  provisions of this Amendment or
the Loan Documents, respectively.

(a) the Fixed Rate and (b) the Prime Rate for such day plus  0.50%.  Any overdue
interest  on the Loan,  to the extent  permitted  by law,  shall bear  interest,
payable on demand,  for each day until paid at a rate per annum equal to the sum
of 2% plus the Fixed Rate.

                  Section  2.5  Fees.  Borrower  shall  pay to Agent for its own
account the agency and other fees relating to the facility  under this Agreement
pursuant to the letter agreement between Borrower and Agent.

                  Section 2.6 Optional Prepayments. Borrower may, upon notice to
Agent given as below  provided,  prepay Loans in whole at any time, or from time
to time in part in amounts  aggregating  $1,000,000  or an integral  multiple of
$500,000  in  excess  thereof,  by paying  the  principal  amount to be  prepaid
together with accrued interest thereon to the date of prepayment;  provided that
any such prepayment  shall be accompanied by the funding losses of Lenders under
Section 2.8.  Borrower  shall give notice to Agent of each  prepayment not later
than 11:00 a.m. (California time) on the third Business Day prior to the date of
prepayment  of any Loans,  specifying  the amount to be prepaid  and the date of
prepayment. Such notice shall not be revocable by Borrower. Upon receipt of such
notice,  Agent shall promptly notify each Lender of the contents  thereof and of
such Lender's ratable share of such prepayment.

                  Section 2.7 General Provisions as to Payments.  Borrower shall
make each  payment  (which  payment  shall be in Dollars) of  principal  of, and
interest  on,  the  Loans  and of fees  hereunder,  not later  than  11:00  a.m.
(California time) on the date when due (and any payment received after such time
on any day shall not be  effective  as a payment for the purpose of  calculating
accrued interest and fees payable under this Agreement until the next succeeding
Business  Day), in federal or other  immediately  available  funds,  to Agent at
Agent's  Funding  Office.  Agent will  promptly  distribute  to each  Lender its
ratable share of each such payment received by Agent for the account of Lenders.
Whenever any payment of principal of, or interest on, the Loans or of fees shall
be due on a day which is not a Business Day, the date for payment  thereof shall
be extended to the next succeeding  Business Day. If the date for any payment of
principal is extended by operation of law or otherwise,  interest  thereon shall
be payable for such extended time.

                  Section 2.8  Funding  Losses.  If  Borrower  makes any payment
(whether  voluntary,  mandatory,  accelerated  or otherwise)  of principal  with
respect to any Loan, pursuant to Article II or Article VI, or otherwise,  on any
day other than the  Maturity  Date,  or if Borrower  fails to borrow the Initial
Loan on the Borrowing  Date,  Borrower shall reimburse each Lender on demand for
any resulting loss or expense  incurred by it (or by any existing or prospective
Participant  in the related  Loan),  including  any loss  incurred in obtaining,

                                       9.
<PAGE>

liquidating,  or employing  deposits  from third persons or in  liquidating  the
Loans  obtained by such Lender in connection  with its Loan;  provided that such
Lender shall have  delivered to Borrower a certificate  as to the amount of such
loss or expense,  which  certificate shall be presumed correct in the absence of
manifest error.

                  Section 2.9  Computation  of Interest  and Fees.  Interest and
fees shall be (a) computed on the basis of a year of 365 days,  and (b) paid for
the actual  number of days elapsed  (including  the first day but  excluding the
last day).

                  Section 2.10 Maximum Interest Rate.  Notwithstanding  anything
to the contrary contained in this Agreement,  Borrower shall not be obligated to
pay, and no Lender shall be entitled to charge,  collect,  receive,  reserve, or
take  interest (it being  understood  that  interest  shall be calculated as the
aggregate of all charges which constitute interest under applicable law that are
contracted for, charged,  reserved,  received, or paid) in excess of the maximum
non-usurious  interest  rate,  as in  effect  from  time to time,  which  may be
charged,  contracted  for,  reserved,  received,  or collected by such Lender in
connection with this Agreement,  the Notes and the other Credit  Documents under
applicable law. For purposes of this Section,  the term  "applicable  law" means
the internal  laws of the State of  California  and, to the extent  controlling,
laws of the United  States of  America,  but,  to the  extent,  contrary  to the
express intent of the parties,  California law is found to be  inapplicable  for
the  purposes  of this  Section,  then  "applicable  law" also means that law in
effect from time to time and applicable to this loan transaction  which lawfully
permits  the  charging  and  collection  of  the  highest  permissible,  lawful,
non-usurious rate of interest on such loan transaction and this Agreement.

                  Section  2.11  Reduced  Return.   If  any  Lender  shall  have
determined  that any new or  additional  applicable  law,  regulation,  rule, or
regulatory requirement  (collectively in this Section  "Requirement")  regarding
capital 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 such  Lender  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 such  Lender'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  such Lender's  policies  with respect to capital  adequacy) by an
amount deemed by such Lender to be material (which amount shall be determined by
such  Lender's  reasonable  allocation  of  the  aggregate  of  such  reductions
resulting  from such  events),  then from time to time,  within 30 Business Days
after  written  demand by such  Lender,  Borrower  shall pay to such Lender such
additional  amount or amounts as will compensate such Lender for such reduction.
Notwithstanding the foregoing,  no additional compensation will be required from
Borrower under this Section if the reason for additional  compensation was based
solely on such Lender's  failure to comply with any existing or new law, treaty,
rule, or regulation or requirement.  In addition, a Lender shall promptly notify
Borrower of any 


                                      10.
<PAGE>

proposed request for compensation  under this Section and shall provide Borrower
with  reasonable  support  therefor.  Any  request  by a Lender  for  additional
compensation shall be structured to allocate such additional costs over the term
of the credit affected thereby.

                  Section 2.12  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 any Lender 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 such Lender to any new or additional
tax of any kind  whatsoever  with respect to this  Agreement,  the Note,  or any
Loan,  or change the basis of taxation of payments to such Lender 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
such Lender);

                  (b) does or  shall  impose,  modify,  or hold  applicable  any
reserve, assessment rate, special deposit, compulsory loan, or other requirement
(collectively  in this  Section,  "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
such Lender;

                  (c) does or shall impose on Lender any other new or additional
condition;  and the result of any of the  foregoing  is to increase  the cost to
such Lender of making, renewing or maintaining its Loans or to reduce any amount
receivable  thereunder  by an  amount  determined  by such  Lender,  in its sole
discretion,  to be material  (which increase or reduction shall be determined by
such Lender'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 such Lender,  within 30 Business Days of its demand,  any
additional  amounts necessary to compensate such Lender for such additional cost
or reduced  amount  receivable as determined by such Lender with respect to this
Agreement.  If any  Lender  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
any Lender 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 if the reason for said additional  compensation  was
based  solely on such  Lender's  failure to comply with any existing or new law,
treaty, rule, regulation,  or requirement.  In addition, a Lender shall promptly
notify Borrower of any proposed request for compensation  under this Section and
shall provide Borrower with reasonable support therefor. Any request by a Lender
for  additional  compensation  shall be structured  to allocate such  additional
costs over the term of the credit affected thereby.

                  Section  2.13  Lender  Withholding  Certificates.  Each Lender
agrees  that it shall  deliver to  Borrower  (with a copy to  Agent):  (i) on or
before the Closing Date either:  (A) a statement that it is  incorporated in the
United  States  of  America,  or  (B) if it is not  so  incorporated,  two  duly
completed copies of United States Internal Revenue Service form 1001 or 4224, as
appropriate,  promulgated  pursuant to the IRC,  indicating  that such Lender is
entitled  to  receive  payments  under  this  Agreement   without  deduction  or
withholding  of any United States  federal income taxes as permitted by the IRC,
(ii) from time to time,  such extensions or renewals of such forms (or successor
forms) as may  reasonably  be  requested by Borrower but only to the extent such
Lender  determines that it may properly effect such extensions or renewals under
applicable  tax treaties,  laws,  regulations,  and  directives and (iii) in the
event of a transfer of any Loan to a Subsidiary or Affiliate of such Lender, two
new duly completed  copies of Internal Revenue Service Form 1001 or 4224 (or any
successor form), as the case may be, for such Subsidiary or Affiliate.  Borrower
and Agent shall each be entitled to rely on such forms in its  possession  until
receipt of any revised or successor form pursuant to the preceding sentence.

                              CONDITIONS PRECEDENT

satisfactory  to it of  telegraphic,  telex,  facsimile  transmission  or  other
written  confirmation  from such party of execution of a  counterpart  hereof by
such party);

                  (b) Receipt by Agent, for the account of Initial Lender,  of a

<PAGE>

delivery  of this  Agreement  and the other  Credit  Documents,  all in form and
substance satisfactory to Agent;

Agent shall promptly  notify Borrower of the Closing Date, and such notice shall
be conclusive and binding on all parties hereto. All documents shall be dated as
of a date reasonably near the Closing Date unless  otherwise  specified or Agent

                  Section  3.2 Borrowing.        

                  The  obligation of Initial  Lender to make the Initial Loan on
the  Borrowing  Date is subject to the  performance  by  Borrower  of all of its
obligations  under  this  Agreement  and to the  satisfaction  of the  following
conditions:

                  (a) The fact  that,  immediately  after  giving  effect to the
Initial Loan, no Default shall have occurred and be continuing;

                  (b) The  fact  that  the  representations  and  warranties  of
Borrower  contained in this Agreement  shall be true and correct in all material
respects on and as of the Borrowing  Date both before and after giving effect to
the Initial Loan;

                  (c) Receipt by Agent from Borrower of a payment in such amount

Section 8.3; and

                  (d) Receipt by Agent of any fees  payable on the Closing  Date

The  acceptance  by  Borrower  of the  Initial  Loan  shall  be  deemed  to be a
representation  and  warranty by Borrower  that,  on the date of such Loan,  and
after giving effect  thereto,  the facts specified in subsections (a) and (b) of
this Section 3.2 are true.


                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                  Borrower  represents  and  warrants  to Agent and each  Lender
that:  

                  Section 4.1 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 would not

                                      13.
<PAGE>

reasonably  be  expected  to result in a  Material  Adverse  Change.  All of the
Subsidiaries  and  Consolidated  Subsidiaries  of Borrower and the percentage of
Borrower's  ownership  interest  therein  as of the date of this  Agreement  are
identified on the Schedule of Subsidiaries.


                  Section  4.2  Authorization.   The  execution,  delivery,  and
performance by Borrower of the Credit Documents,  and the obtaining of the Loans
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.

                  Section  4.3  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)  is required  for the due  execution,  delivery,  and  performance  by
Borrower of the Credit Documents.

                  Section 4.4  Validity.  The Credit  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.

                  Section 4.5 Financial  Condition.  The Base Financials  fairly
present the financial condition of Borrower and its Consolidated Subsidiaries as
at the date  thereof  and the  results of the  operations  of  Borrower  and its
Consolidated  Subsidiaries for the respective periods ended on such date, all in
accordance with GAAP,  consistently  applied.  Since January 1, 1997,  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.

                  Section  4.6  Litigation.  Except  as set  forth  in the  Base
Financials,  there  is no  pending  or,  to the  best of  Borrower's  knowledge,
threatened,  action or proceeding  affecting Borrower or any of its Consolidated
Subsidiaries before any court,  governmental agency, or arbitrator,  which would
be reasonably likely to result in a Material Adverse Change.

                  Section  4.7  ERISA  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 result in a Material Adverse Change.

                  Section  4.8  Disclosure.  No  representation  or  warranty of
Borrower  contained in this  Agreement or any other  document,  certificate,  or
written  statement  furnished 


                                      14.
<PAGE>

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 Agent for use in
connection with the transactions contemplated hereby.

                  Section 4.9 Margin Stock.  The  aggregate  value of all margin
stock (as defined in the Margin  Regulations)  directly or  indirectly  owned by
Borrower and its  Consolidated  Subsidiaries  is less than 25% of the  aggregate
value of Borrower's assets.

                  Section 4.10 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
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  result  in a  Material  Adverse  Change;  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
would reasonably be expected to result in a Material  Adverse Change.  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 would  reasonably be expected to result in a Material  Adverse Change;  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 result in a Material Adverse Change 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 would  reasonably  be  expected  to result in a
Material Adverse Change; and 


                                      15.
<PAGE>

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  result  in a  Material  Adverse  Change  for all such  outstanding
charges.

                  Section  4.11 Not an  Investment  Company.  Borrower is not an
"investment  company" within the meaning of the Investment  Company Act of 1940,
as amended.

                  Section  4.12 Margin  Regulations.  Borrower is not engaged in
the  business  of  extending  credit for the purpose of  purchasing  or carrying
margin stock (within the meaning of the Margin Regulations).

                  Section  4.13  Events of Default.  No Default has  occurred or
would result from the incurring of  obligations by Borrower under this Agreement
or any other Credit Document.

                  Section  4.14  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.


                                    ARTICLE V

                                    COVENANTS

                  Borrower agrees that, so long as any amount payable  hereunder

each Lender:

such fiscal quarter,  setting forth in each case in comparative form the figures

previous   fiscal  year,  all  certified   (subject  to  normal  year-end  audit

times preserve and keep in full force and effect Borrower's and its Consolidated

(including,  without  limitation,  claims for labor,  services,  materials,  and
supplies)  for sums which have  become due and  payable and which by law have or
may become a lien upon any of its  properties or assets,  prior to the time when
any penalty or fine 


                                      18.

of  established  reputation  engaged  in the  same  or  similar  businesses  and
similarly situated, of such types and in such amounts as are customarily carried
under similar circumstances by such other corporations.

                  Section 5.6  Inspection.  Borrower shall permit any authorized
representatives  designated by Agent at the request of Required Lenders to visit

accounting  records,  and to make  copies and take  extracts  therefrom,  and to
discuss  its and  their  affairs,  finances,  and  accounts  with its and  their
officers and independent public accountants, all at such reasonable times during
normal  business hours and under  Borrower's  supervision and as often as may be
reasonably  requested.  Any such  additional  information  together  with  other
nonpublic  information  received  hereunder  shall be held in  confidence by the
recipients thereof and may not be used for any purpose other than to monitor the
creditworthiness   of  Borrower  and  its  Consolidated   Subsidiaries   (except

income,  in each  case to secure  any Debt of any  Person  other  than (i) Liens

consolidation   or  merger  there  shall  exist  no  condition  or  event  which
constitutes  a  Default.   In  addition   Borrower  may  purchase  any,  all  or
substantially  all  of the  assets  of  any  other  Person  in  connection  with

incidental thereto.

                  Section  7.2 Agent  and  Affiliates.  IBJ shall  have the same

Credit  Documents,  and (b) with respect to any provision of any Credit Document
which authorizes  Agent to give any consent or approval,  impose any requirement
or take any other discretionary  action,  Agent may, but is not required to, use
its own discretion in determining whether to take any such action, and (c) as to
(i) matters requiring or permitting an approval,  consent,  waiver,  election or
other action by Required Lenders, (ii) matters as to which,  notwithstanding any
delegation of authority to Agent, Agent has requested instructions from Required
Lenders,  and (iii) matters not expressly  provided for by the Credit Documents,
Agent shall not be required to exercise any  discretion or take any action,  but
shall be  required  to act or to refrain  from  acting  only (and shall be fully
protected  in so acting or  refraining  from acting)  upon the  instructions  of
Required  Lenders,  and such  instructions  shall be binding  upon all  Lenders;
provided  that Agent shall not be required to take any action  which in the good
faith judgment of Agent would expose Agent to personal  liability or is contrary
to any Credit  Document or applicable  law. Agent may treat each existing Lender
as the holder of the right to  payment  of its  outstanding  Loans  until  Agent
receives and accepts an Assignment and Acceptance  signed by such Lender and its
Assignee in accordance with the provisions of this Agreement.

                  Section 7.4 Consultation with Experts.  Agent may consult with
legal counsel (including counsel to Borrower),  independent public  accountants,
and other experts selected by it and shall not be liable for any action taken or
omitted  to be taken by it in good faith in  accordance  with the advice of such
counsel, accountants, or experts.

                  Section  7.5  Liability  of  Agent.   Neither  Agent  nor  any
director, officer, agent, or employee of Agent shall be liable to any Lender for
any action taken or not taken by it in connection with the Credit  Documents (a)
with the consent or at the request of 


                                      25.
<PAGE>

Required  Lenders or (b) in the absence of its own gross  negligence  or willful
misconduct. Neither Agent nor any director, officer, agent, or employee of Agent
shall be responsible for or have any duty to ascertain, inquire into, or verify:
(i) any  statement,  warranty,  or  representation  made in connection  with the
Credit Documents or any borrowing hereunder;  (ii) the performance or observance
of any of the covenants or agreements of Borrower in the Credit Documents; (iii)
the  satisfaction  of any  condition  specified  in  Article  III;  or (iv)  the
validity,  effectiveness,  or  genuineness  of any Credit  Document or any other
instrument or writing furnished in connection  therewith.  Agent shall not incur
any liability by acting in reliance upon any notice or any consent, certificate,
statement,  or other  writing  (which  may be a bank  wire,  telex,  or  similar
writing)  believed by it to be genuine or to have been given or be signed by the
proper party or parties.

                  Section 7.6  Indemnification.  Each Lender  shall,  ratably in
accordance  with its Loans,  indemnify  Agent (to the extent not  reimbursed  by
Borrower) against any cost,  expense  (including  counsel fees and disbursements
and allocated costs for in-house legal services),  claim, demand,  action, loss,
or liability  (except such as result from Agent's  gross  negligence  or willful
misconduct)  that Agent may suffer or incur,  or which may be  asserted  against
Agent,  directly or indirectly  arising out of or in connection  with the Credit
Documents  or any  action  taken or omitted by Agent  thereunder  or  incidental
thereto.

                  Section 7.7 Credit Decision.  Each Lender acknowledges that it
has,  independently  and without  reliance upon Agent or any other  Lender,  and
based on such documents and information as it has deemed  appropriate,  made its
own credit analysis and decision to enter into this Agreement.  Each Lender also
acknowledges that it will,  independently and without reliance upon Agent or any
other  Lender,  and based on such  documents  and  information  as it shall deem
appropriate at the time,  continue to make its own credit decisions in taking or
not taking any action under the Credit Documents.

                  Section 7.8 Successor  Agent.  Agent may resign at any time by
giving  written   notice  thereof  to  Lenders  and  Borrower.   Upon  any  such
resignation, Borrower shall have the right, with the consent of Required Lenders
(which  consent  shall not be  unreasonably  withheld),  to appoint a  successor
Agent.  If no successor  Agent shall have been so appointed by Borrower with the
consent of Required Lenders and shall have accepted such  appointment  within 30
days  after the  retiring  Agent's  giving of  notice of  resignation,  then the
retiring  Agent may appoint a successor  Agent which shall be a commercial  bank
organized or licensed  under the laws of the United  States of America or of any
State   thereof  and  having  a  combined   capital  and  surplus  of  at  least
$100,000,000.  Upon the acceptance of its  appointment  as Agent  hereunder by a
successor  Agent,  such successor  Agent shall  thereupon  succeed to and become
vested with all the rights and duties of the  retiring  Agent,  and the retiring
Agent  shall be  discharged  from its  duties and  obligations  under the Credit
Documents.  After any  retiring  Agent's  resignation  hereunder  as Agent,  the
provisions  of this  Article  VII shall  inure to its  benefit as to any actions
taken or omitted to be taken by it while it was Agent.

                  Section 7.9  Collateral.  Each of Lenders  represents to Agent
and each other  Lender  that it in good faith is not  relying  upon any  "margin
stock" (as defined in the Margin  Regulations) as collateral in the extension or
maintenance of any Loan.

                  Section  7.10  Agent/Borrower  Relationship.   The  protective
provisions set forth in Article VII relating to the Agent are intended to govern
the relationship  between the Agent and the Lenders and shall not be interpreted
to decrease or increase the liability of the Agent as concerns its  relationship
with Borrower.


                                  ARTICLE VIII

                                  MISCELLANEOUS

                  Section  8.1  Notices.  All  notices,   requests,   and  other
communications  to any party under this Agreement  shall be in writing and shall
be given to such party at its address or telex or facsimile  number set forth on
the  signature  pages  hereof (or in the case of an Assignee as set forth on the
signature pages of the relevant Assignment and Acceptance) or such other address
or telex or facsimile number as such party may hereafter specify for the purpose
by  notice  to  Agent  and  Borrower.   Each  such  notice,   request  or  other
communication shall be effective: (a) if given by telex or facsimile,  when such
telex  or  facsimile  is  transmitted  to the  telex  or  facsimile  number,  as
applicable,  specified  in  this  Section  and,  in the  case  of  telexes,  the
appropriate  answer back is received and, in the case of  facsimiles,  the party
sending the facsimile has telephonically  confirmed its receipt, (b) if given by
registered or certified  mail,  return  receipt  requested,  72 hours after such
communication  is  deposited  in the mails with  postage  prepaid,  addressed as
aforesaid  or (c) if given by any other  means,  when  delivered  at the address
specified in this Section 8.1;  provided that any  communications to Agent under
Article II  (including  any  communication  required in order to  ascertain  the
applicable rates of interest  thereunder)  shall not be effective until received
by Agent. In the event of any conflict  between any oral  communication to Agent
and the written confirmation  thereof,  such oral communication shall control if
Agent has acted thereon prior to actual receipt of such written confirmation.


                  Section 8.2 No Waivers;  Rights and  Remedies  Cumulative.  No
failure  or delay by Agent or any Lender in  exercising  any  right,  power,  or
privilege  under any Credit Document shall operate as a waiver thereof nor shall
any single or partial  exercise  thereof  preclude any other or further exercise
thereof or the exercise of any other right, power, or privilege.  The rights and
remedies  provided in the Credit Documents shall be cumulative and not exclusive
of any rights or remedies provided by law.

                  Section 8.3 Expenses and Indemnity.

                  (a) Borrower  agrees to pay, within 30 days of demand therefor
(but on demand if there  shall then exist any Event of  Default),  all costs and
expenses (i) of Agent 


                                      27.
<PAGE>

(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 Credit  Documents,  and (ii) of
Agent or any  Lender in  connection  with the  enforcement  (including,  without
limitation, in appellate, bankruptcy, insolvency,  liquidation,  reorganization,
moratorium,  or  other  similar  proceedings)  or  restructuring  of the  Credit
Documents;  provided  that  Borrower's  obligation  to reimburse  Agent for such
attorneys' fees in connection with the preparation of the Credit Documents shall
be limited to $15,000; provided, further, that Agent and Lenders shall use their
best  efforts to utilize  the same legal firm to  represent  them with regard to
Borrower's obligations hereunder.

                  (b) Whether or not the transactions  contemplated hereby shall
be consummated,  Borrower  agrees to indemnify,  pay and hold Agent and Lenders,
and the shareholders,  officers,  directors,  employees, and agents of Agent and
Lenders,  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  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 any outstanding Notes.

                  Section 8.4 Offset; Sharing of Recoveries.

                  (a) Upon the  occurrence  and  during the  continuance  of any
Event of Default,  each Lender, upon prior notice to Agent and all other Lenders
and only with the consent of Required Lenders,  is hereby authorized at any time
and from time to time,  to the fullest  extent  permitted by law, to set-off and
apply any and all  deposits  (general or special,  time or demand,  provision or
final) at any time held and other  indebtedness at any time owing by such Lender
to or for the credit or the account of Borrower against an equivalent  amount of
Loans,  irrespective  of whether or not such  Lender  shall have made any demand
under this Agreement and although such obligations may be unmatured. Each Lender
agrees  promptly  to notify  Borrower  and  Agent  after  any such  set-off  and
application  is made by such  Lender,  provided  that the  failure  to give such
notice shall not affect the validity of such set-off and application. The rights
of each Lender  under this  Section  8.4(a) are in addition to other  rights 


                                      28.
<PAGE>

and remedies (including, without limitation, other rights of set-off) which such
Lender may have. Borrower agrees, to the fullest extent it may effectively do so
under  applicable law, that any holder of a participation in any Lender's Loans,
whether or not acquired  pursuant to the  foregoing  arrangements,  may exercise
rights  of  set-off  or  counterclaim  and other  rights  with  respect  to such
participation  as  fully  as if such  holder  of a  participation  were a direct
creditor  of  Borrower  in the  amount  of  such  participation,  and  any  such
participant by so exercising such rights agrees to be bound by the provisions of
Section 8.4(b).

                  (b) Except for a prepayment  received by a Lender  pursuant to
Section 8.5(b),  each Lender agrees that if it shall, by exercising any right of
set-off,  counterclaim,  security interest,  or otherwise,  receive payment of a
proportion of the aggregate amount of principal and interest due with respect to
any  Loans by it which is  greater  than the  proportion  received  by any other
Lender in respect of the  aggregate  amount of  principal  and interest due with
respect to Loans by such other Lender, the Lender receiving such proportionately
greater  payment  shall  purchase  such  participations  in Loans  by the  other
Lenders,  and such other  adjustments  shall be made, as may be required so that
all such  payments of principal  and  interest  with respect to Loans by Lenders
shall be shared by Lenders pro rata;  provided that (i) if all or any portion of
such payment is thereafter  recovered  from such Lender,  such purchase shall be
rescinded and the purchase price  restored to the extent of such  recovery,  but
without interest, and (ii) nothing in this Section shall impair the right of any
Lender to exercise any right of set-off or counterclaim it may have and to apply
the amount subject to such exercise to the payment of  indebtedness  of Borrower
other than the Loans.

                  (c) From and after the first to occur of (x) any  acceleration
of maturity of the Notes  pursuant to Section 6.1 or (y) the Maturity  Date, and
so long as any Loan remains outstanding,  sums received by Agent for application
to any Loan (and whether received by voluntary payment, set-off,  disposition of
collateral or otherwise)  shall be applied by Agent in the following  order: (i)
to costs and expenses and other amounts  payable to Agent pursuant to the Credit
Documents,  (ii) to interest on the Loans,  (iii) to the Loans,  and (iv) to the
other obligations in such order as Required Lenders and Agent shall agree.

                  Section 8.5 Amendments and Waivers.

                  (a) Any  provision of the Credit  Documents  may be amended or
waived if, but only if, such  amendment or waiver is in writing and is signed by
Borrower  and  Agent  with the  consent  of  Required  Lenders,  whereupon  such
amendment  or waiver  shall be binding  on all  Lenders;  provided  that no such
amendment or waiver  shall,  unless  consented to by Agent and all Lenders,  (i)
reduce the  principal  of or rate of interest on any Loan or any fees  hereunder
(other than fees payable solely to Agent in which case only the consent of Agent
shall be required), (ii) postpone the date fixed for any payment of principal of
or interest on any Loan or any fees hereunder, or (iii) change the definition of
"Required  Lenders"  or  otherwise  change the number of Lenders  which shall be
required for Lenders or any of them to take any action under this Section 8.5 or
any other provision of the Credit Documents. No 


                                      29.
<PAGE>

amendment of the duties of Agent hereunder,  or of the immunities,  indemnities,
and  protections  afforded to Agent by Article  VII,  shall be made  without the
consent of Agent.

                  (b) If Borrower  requests a modification of the type specified
in clauses (i) through (iii) of subsection (a) above (a "Modification  Request")
and any  Lender  (other  than  IBJ) or  Participant  refuses  to  agree  to such
modification (a  "Nonaccepting  Entity"),  Agent shall use good faith efforts to
secure a substitute  Lender or participant  acceptable to Borrower and Agent and
willing to accept such modification as a replacement for the Nonaccepting Entity
(an  "Accepting  Entity")  and, if Agent shall be unable to secure an  Accepting
Entity  within  50 days  from  Agent's  receipt  from  Borrower  of the  related
Modification  Request,  then  Borrower may, at its option so long as no Event of
Default would result therefrom,  prepay all but not less than all of the Loan or
participation  interest of such  Nonaccepting  Entity (A) without  obtaining the
consent  of any  Person if the  principal  amount of such Loan or  participation
interest  is less than  $25,000,000  and (B) with the  consent  of the  Required
Lenders  (for the purpose of  determining  such  Required  Lenders  such Loan or
participation interest of such Nonaccepting Entity shall not be included) if the
principal  amount  of such  Loan  or  participation  interest  is  greater  than
$25,000,000;   incident  to  such   prepayment,   Borrower  shall  pay  to  such
Nonaccepting  Entity  the  outstanding  principal  amount  of such  Nonaccepting
Entity's Loan or participation interest, accrued interest thereon to the date of
prepayment,  amounts to which such  Nonaccepting  Entity is entitled pursuant to
Section  2.8 by  reason  of such  prepayment,  and all the  amounts  then  owing
hereunder by Borrower to such  Nonaccepting  Entity.  Upon any such  prepayment,
Borrower shall give Agent and Lenders immediate notice thereof.

                  Section 8.6 Successors and Assigns; Participations.

                  (a) This  Agreement  shall be  binding  upon and  inure to the
benefit of the  parties  hereto and their  respective  successors  and  assigns,
except  (i) that  Borrower  may not  assign  or  transfer  any of its  rights or
obligations  under this  Agreement  or any other  Credit  Document  without  the
consent of all  Lenders  and (ii) no Lender may  assign or  transfer  any of its
rights or obligations  under this Agreement,  except to the extent  permitted by
this Section 8.6.

                  (b)  Any   Lender  may  at  any  time  sell  to  one  or  more
institutional  lenders  (each  a  "Participant")   proportionate   participating
interests in all Loans owing to such Lender,  the Note held by such Lender,  and
in any other interest of such Lender  hereunder;  provided that no participating
interest  may be sold by a Lender  pursuant to this  subsection  (b): (w) to any
Participant  that is not then a  Participant  or Lender  without  the consent of
Borrower and Agent,  (which consent may not be  unreasonably  withheld),  (x) if
after giving effect  thereto,  the Loan of such Lender which is held for its own
account  (and not on  behalf  of  participating  interests)  would be less  than
$15,000,000,  (y) if such participating interest is equivalent to a Loan of less
than  $15,000,000,  or (z) on a basis  which  permits the  Participant  to grant
subparticipations  with respect to or to otherwise transfer less than all of its
participating  interest to any Person. In the event of any such sale by a Lender
of a participating  interest to


                                      30.
<PAGE>

a  Participant,  such Lender's  obligations  under this  Agreement and the other
Credit  Documents  shall  remain  unchanged,  such Lender  shall  remain  solely
responsible for the performance thereof,  such Lender shall otherwise remain the
holder of any such Note for all purposes under this Agreement,  and Borrower and
Agent shall  continue to deal solely and directly with such Lender in connection
with such Lender's  rights and  obligations  under this  Agreement and the other
Credit Documents.  Subject to the provisions of this Section 8.6(b), each Lender
shall be  entitled  to obtain (on behalf of the  Participants)  the  benefits of
Sections  2.8,  2.11 and 2.12 with  respect to all  participations  in its Loans
outstanding  from time to time.  No Lender shall grant any  participation  under
which the Participant shall have rights to approve (or shall require the consent
of such  Participant  before such Lender may approve) any amendment to or waiver
of this Agreement or the other Credit  Documents or the extension of any date on
which any principal, interest or other sums payable hereunder are due, except to
the extent  such  amendment  or waiver:  (i) reduces the rate of interest on any
Loan, (ii) reduces the amount of principal  payable on any Loan or (iii) extends
the  Maturity  Date.  Not less than five  Business  Days  after the grant of any
participating interest to a Participant, the Lender granting such interest shall
notify Agent and Borrower of the name of the  Participant  and of the nature and
extent of the participating interest granted to such Participant.

                  (c)  Any   Lender  may  at  any  time  sell  to  one  or  more
institutional  lenders  (each  an  "Assignee")  all,  or  a  proportionate  part
(equivalent  to a Loan of not less than  $15,000,000)  of all, of its rights and
obligations  under this Agreement and the Notes,  and such Assignee shall assume
all such  rights and  obligations,  pursuant  to an  Assignment  and  Acceptance
executed by such Assignee and such transferor Lender;  provided that no interest
may be sold by a Lender  pursuant to this subsection (c) to any Assignee that is
not then a Lender without the consent of Borrower and Agent,  (which consent may
not be unreasonably  withheld);  and provided further that no interest less than
all of  such  Lender's  interest  may be  sold  by a  Lender  pursuant  to  this
subsection (c) if, after giving effect thereto, such Lender's Loan would be less
than  $15,000,000.  Upon (i) such execution of such  Assignment and  Acceptance,
(ii) delivery by the  transferor  Lender of an executed  copy thereof,  together
with notice that the payment  referred to in clause  (iii) below shall have been
made, to Borrower,  Agent and each Lender, and (iii) payment by such Assignee to
such  transferor  Lender of an amount equal to the purchase price agreed between
such transferor  Lender and such Assignee,  such Assignee shall for all purposes
be a  Lender  party  to  this  Agreement  and  shall  have  all the  rights  and
obligations of a Lender under this  Agreement and the other Credit  Documents to
the same extent as if it were an original party hereto with a Loan in the amount
set forth in such Assignment and Acceptance,  and the transferor Lender shall be
released  from its  obligations  hereunder  to a  corresponding  extent,  and no
further consent or action by Borrower,  Lenders or Agent shall be required. Upon
the consummation of any transfer to an Assignee  pursuant to this subsection (c)
the transferor Lender, Agent and Borrower shall make appropriate arrangements so
that,  if required,  new Notes are issued to such Assignee and, to the extent it
remains a Lender  hereunder,  such transferor  Lender,  and upon the issuance of
such new Note(s),  such transferor Lender shall surrender the existing Note held
by it.

<PAGE>

                  (d) Any  Lender  may at any time  pledge or assign  all or any
part of (or a  proportionate  participating  interest in) such  Lender's  rights
under the Credit  Documents  to any  Federal  Reserve  Bank in  accordance  with
applicable law.

                  (e)  Borrower  authorizes  each  Lender  to  disclose  to  any
Participant or Assignee (a "Transferee") and any prospective Transferee, any and
all financial  information in such Lender's possession concerning Borrower which
has been  delivered  to such Lender by Borrower  pursuant to this  Agreement  or
which has been  delivered  to such Lender by Borrower  in  connection  with such
Lender's credit evaluation prior to entering into this Agreement,  provided that
such  Transferee or  prospective  Transferee has first agreed to be bound by the
provisions of Section 8.10 and executed the required Confidentiality Letter.

                  (f) If pursuant to  subsection  (c) of this  Section  8.6, any
interest in this  Agreement or any Note is  transferred to any Assignee which is
organized  under the laws of any  jurisdiction  other than the United  States of
America or any State thereof,  the transferor  Lender shall cause such Assignee,
concurrently  with the  effectiveness of such transfer,  (i) to represent to the
transferor  Lender  (for  the  benefit  of the  transferor  Lender,  Agent,  and
Borrower) that under applicable law and treaties no taxes will be required to be
withheld  by Agent,  Borrower,  or the  transferor  Lender  with  respect to any
payments to be made to such Assignee in respect of the Loans, (ii) to furnish to
each of the transferor Lender,  Agent, and Borrower two duly completed copies of
either U.S.  Internal Revenue Service Form 4224 or U.S. Internal Revenue Service
Form 1001 (wherein such Assignee claims  entitlement to complete  exemption from
U.S. federal  withholding tax on all interest  payments  hereunder) and (iii) to
agree (for the benefit of the transferor Lender, Agent, and Borrower) to provide
the transferor Lender, Agent, and Borrower a new Form 4224 or Form 1001 upon the
obsolescence  of any  previously  delivered  form and  comparable  statements in
accordance  with  applicable  U.S.  laws and  regulations  and  amendments  duly
executed and  completed by such  Assignee,  and to comply from time to time with
all applicable  U.S. laws and  regulations  with regard to such  withholding tax
exemption.

                  (g) No  Transferee  (including  for this  purpose a  different
Lending  Office of a Lender)  shall be entitled  to receive any greater  payment
under Sections 2.11 and 2.12 than the transferor Lender would have been entitled
to receive with respect to the rights  transferred,  unless such  assignment  or
participation is made with the prior written consent of Borrower.

                  Section  8.7   Obligations   of  Lenders  are   Several.   The
obligations of each Lender under this  Agreement are several.  Neither Agent nor
any Lender  shall be liable for the  failure of any other  Lender to perform its
obligations under this Agreement.

                  (a)  GOVERNING  LAW.  THIS  AGREEMENT  AND  THE  OTHER  CREDIT
DOCUMENTS (EXCEPT TO THE EXTENT OTHERWISE  EXPRESSLY SET
