                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)
                                  JULY 4, 1999


NOTE 1 - BASIS OF PRESENTATION

         The accompanying  unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial  information and with the  instructions to Form 10-Q and Article 10 of
Regulation  S-X.  Accordingly,  they do not include all of the  information  and
footnotes  required by generally  accepted  accounting  principles  for complete
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring accruals)  considered necessary for a fair presentation have
been included. Operating results for the three- and six-month periods ended July
4, 1999 are not  necessarily  indicative of the results that may be expected for
the year ending January 2, 2000.

         The financial  statements  have been prepared on a going concern basis.
The Report of Independent Auditors on the Company's financial statements for the
year ended January 3, 1999 included in the Company's  Annual Report on Form 10-K
contained an explanatory  paragraph which indicated  substantial doubt about the
Company's  ability to continue as a going  concern  because of recent  operating
losses  and lack of  compliance  with  certain  covenants  of its  various  bank
agreements.  Such  non-compliance  constitutes  an event of  default  under  the
agreements.  The Company  has not been in payment  default  under  these  credit
facilities  and has  continued  to pay  all  interest  charges  and  other  fees
associated  with  these  facilities  on  their  scheduled  due  dates.   Amounts
outstanding  under these unsecured credit agreements at July 4, 1999 amounted to
$260 million.  To date, the Company's lenders have not accelerated any principal
payments under these facilities.  The Company is currently  negotiating with its
lenders  for  amendments  to its  existing  credit  facilities.  There can be no
assurance that the Company will be able to obtain such  amendments to its credit
facilities on commercially  reasonable terms. In the event that the Company does
not   successfully   amend  its  credit   facilities  or  restructure  its  debt
obligations,  the Company could be required to significantly  reduce or possibly
suspend its operations, and/or sell additional securities on terms that would be
highly dilutive to current stockholders of the Company. The financial statements
do not include any  adjustments  to reflect the possible  future  effects on the
recoverability and classification of assets or the amounts and classification of
assets and liabilities that may result from the outcome of this uncertainty.

         For further information, refer to the consolidated financial statements
and footnotes  thereto  included in the Company's Annual Report on Form 10-K for

         The Company uses a 52-53 week fiscal year ending on the Sunday  closest
to December  31. The three- and  six-month  reporting  periods  included in this
report are comprised of thirteen and twenty-six weeks, respectively.


NOTE 2 - INVESTMENT IN DEBT SECURITIES

         The Company  invests its excess cash in  high-quality,  short-term debt

         The Company  utilizes  zero-balance  accounts and other cash management
tools to invest all available  funds  including  bank balances in excess of book
balances.


NOTE 3 - INCOME TAXES

         The Company's income tax provisions of  approximately  $0.4 million and
$0.8 million for the three- and six-month  periods ended July 4, 1999  primarily
represent foreign withholding taxes. The Company's  wholly-owned thin-film media
operation,  Komag USA  (Malaysia)  Sdn.  ("KMS")  received an  extension  of its
initial five-year tax holiday for an additional five years commencing July 1998.
KMS has also been  granted a ten-year tax holiday for its second and third plant
sites in Malaysia.  The commencement  date for this new tax holiday has not been
determined as of August 4, 1999.

NOTE 6 - 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 7 - PURCHASE OF WESTERN DIGITAL CORPORATION'S MEDIA OPERATIONS

         In April 1999,  the  Company  purchased  the assets of Western  Digital
Corporation's  ("WDC's") media operations  through the issuance of approximately
10.8 million  shares of the  Company's  Common Stock and a note in the principal
amount of $30.1 million. The shares issued in the transaction, which represented
16.7%  of  the  Company's  outstanding  shares  on a  post-issuance  basis,  are
unregistered and subject to trading restrictions. WDC may resell these shares in
specified  increments  over a three and one-half year period under  registration
rights  granted  by the  Company  or under SEC  rules  after  expiration  of the
required holding periods.  Principal and interest accrued on the note are due in
three  years  and the  note  is  subordinated  to the  Company's  senior  credit
facilities.  In the event WDC realizes a return on its Komag equity  holdings in
excess of a targeted  amount  within three years,  the excess amount will reduce
the balance due under the note. The Company  discounted the principal  amount of
the subordinated note payable to $21.2 million based on the Company's  estimated
incremental borrowing rate of 18% for this class of financial instrument.

         Additionally,  the Company and WDC signed a volume  purchase  agreement
under which the Company  agreed to supply a  substantial  portion of WDC's media
needs over the next three years.  Under the volume purchase  agreement WDC began
to purchase  substantially all of its media  requirements from the Company after
the closing date. The Company  initially  expected that second quarter 1999 unit
sales  from the  combined  operations  would grow  sequentially  in the range of
20-35%  compared to the Company's  first  quarter of 1999  results.  Actual unit
shipments for the second quarter fell considerably  short of these  expectations
as customer order reductions (including those from WDC) and  lower-than-expected
volumes on certain new product programs restricted

                                      -9-

<PAGE>


sequential  unit sales growth to  approximately  10%. In response to competitive
market conditions the Company's  customers reduced the number of disks per drive
to support the  delivery of lower  priced disk drives to the rapidly  expanding,
low-cost  segment of the PC  market.  These  customer  actions,  the  continuing
imbalance  between the supply and demand for disk products,  and the lack of new
data-intensive   applications   continue  to  depress  the  Company's  financial
performance.  Due to this weak unit  demand  the  Company  closed the former WDC
media  operation  at the end of June 1999,  nearly  fifteen  months ahead of the
Company's original transition plan.

         The Company's  acquisition of WDC's media operation was recorded in the
second quarter of 1999 as a business  combination  using the purchase  method of
accounting. Under this method the Company recorded the following (in millions):

         The Company recognized  goodwill and other intangibles in the amount of
$83.9  million in connection  with the  acquisition  of WDC's media  operations.
Goodwill  typically reflects the difference between the fair value of the assets
acquired and  consideration  paid.  Under purchase  accounting rules the Company
also recorded  liabilities  that  increased  the amount of goodwill  recognized.
These  liabilities  included  estimated  costs for the closure of the former WDC
media operation as well as costs related to the remaining lease  obligations for
equipment taken out of service due to the closure. The Company is amortizing the
goodwill over the three-year  life that coincides

                                      -10-

with the term of the Company's volume purchase agreement with WDC.

         During the second quarter of 1999 the Company paid  approximately  $2.9
million  against these  liabilities  primarily for equipment  lease  obligations
($2.4 million) and other liabilities ($0.5 million). Equipment lease obligations
are expected to be paid monthly  through  mid-2002.  At July 4, 1999 the current
portion of the equipment  lease  obligations  was  approximately  $10.3 million.
Facility closure costs,  purchase order cancellation costs and other liabilities
associated with the WDC transaction are expected to be paid by mid-2000.

                               KOMAG, INCORPORATED

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Results of Operations:

         The  following  discussion  contains  predictions,  estimates and other
forward-looking  statements  that  involve a number of risks and  uncertainties.
These  statements  may be  identified  by the use of  words  such as  "expects,"
"anticipates,"   "intends,"  "plans,"  and  similar   expressions.   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.  In particular,  the
actions  taken to  restructure  it U.S.  operations  might disrupt the Company's
ability to execute against  customer  obligations  and  operational  improvement
plans. Such failures to execute would jeopardize the anticipated improvements in
the Company's financial  performance  outlined below. Due to the volume purchase
agreement  with Western  Digital  Corporation  ("WDC"),  the  Company's  results
continue to remain highly  dependent on the relative  success of WDC in the data
storage market.  Other factors that could cause actual results to differ include
the following:  disk consumption per drive based on the relative growth rates of
areal  density and overall  storage  usage;  pricing  levels  determined  by the
continuing imbalance between supply and demand for disk products; growth rate of
the merchant disk market as influenced by the level of captive disk  production;
structural  changes  within the disk  media  industry  created by  combinations,
failures, and joint venture arrangements;  unit volumes derived from new product
qualifications;  changes in manufacturing  efficiencies,  in particular  product
yields and  material  input  costs;  factory  utilization  levels;  and  capital
expenditure  levels  required  to  maintain or acquire  process  equipment  with
capabilities to meet more stringent future product requirements.  Moreover,  the
Company must maintain  sufficient  cash  resources to operate  efficiently.  The
Company's ability to raise additional  funding,  if required,  will be dependent
upon  improvement in the Company's  financial  performance and the status of the
Company's credit facilities.  Improvement in the Company's financial performance
remains highly dependent on macro industry fundamentals. Other risk factors that
may affect  the  Company's  financial  performance  are listed in the  Company's
various SEC filings,  including  its Form 10-K for the fiscal year ended January
3, 1999 which was filed on April 2, 1999.  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.

Overview:

         Adverse market conditions, which began in mid-1997, continued to impact
the thin-film media market  throughout  1998 and the first half of 1999.  Demand
for disk drives grew rapidly  during the mid-1990s and industry  forecasts  were
for continued

                                      -12-

strong growth.  The Company and a majority of its competitors  (both independent
disk manufacturers and captive disk manufacturers owned by vertically integrated
disk drive customers)  committed to expansion programs in 1996 and substantially
increased their media manufacturing capacity in 1997. In 1997 the rate of growth
in demand for disk drives fell. Disk drive manufacturers abruptly reduced orders
for media from  independent  suppliers  and  relied  more  heavily  on  internal
capacity to supply a larger  proportion of their media  requirements.  The media
industry's capacity  expansion,  coupled with the decrease in the rate of demand
growth,  has resulted in excess  media  production  capacity.  This excess media
production  capacity  caused sharp  declines in average  selling prices for disk
products as independent suppliers struggled to utilize their capacity.

         In addition to adversities  caused by the excess supply of media,  1998
was a year of tremendous transition for the Company and the disk drive industry.
Disk drive programs  utilizing  newer,  more advanced,  magnetoresistive  ("MR")
media and recording heads replaced older generation programs utilizing inductive
media and heads. By the end of 1998 most disk drives were  manufactured  with MR
components.   The  transition  to  MR  disk  drives  has  led  to   significant,
unprecedented increases in areal density and, therefore, the amount of data that
can be stored on a single disk platter. In the first and second quarters of 1999
the majority of the Company's 3 1/2-inch  disks were capable of storing at least
4.3 gigabytes (GB) per platter. This represented a 34% increase in disk capacity
relative to a product mix of predominately 3.2 GB platters in the fourth quarter
of 1998.  The  Company  expects 3 1/2-inch  disks  capable of storing 6.8 GB per
platter will account for the majority of the Company's unit shipments during the
second half of 1999.  Increased  disk  storage  capacity  per disk allows  drive
manufacturers  to offer  lower-priced  disk  drives  at given  capacity  points,
especially in the price-sensitive desktop segment,  through the incorporation of
fewer  components  into  their disk  drives.  The rapid  advancement  in storage
capacity  per disk  platter  has  further  slowed  disk  demand  throughout  the
industry. According to industry market analysts, this resulting reduction in the
average  number of disks per drive  will  likely  slow the  growth  rate of disk
shipments  below the growth rate of disk drives  during  1999.  The  significant
amount of captive  capacity  employed by certain disk drive  manufacturers  also
continues to reduce the market opportunities for independent disk suppliers such
as the Company.

         In April 1999, the Company  acquired the thin-film media  operations of
Western Digital Corporation  ("WDC"). As part of the acquisition the Company and
WDC also entered into a volume purchase agreement under which the Company agreed
to supply a substantial portion of WDC's thin-film media requirements. Under the
volume purchase  agreement WDC began to purchase  substantially all of its media
requirements  from the Company  after the closing  date.  The Company  initially
expected that second quarter 1999 unit sales from the combined  operations would
grow sequentially in the range of 20-35% compared to the Company's first quarter
of 1999 results.  Actual unit shipments for the second quarter fell considerably
short of these  expectations as customer order

                                      -13-

<PAGE>


reductions (including those from WDC) and lower-than-expected volumes on certain
new product  programs  restricted  sequential unit sales growth to approximately
10%.  In response to  competitive  market  conditions  the  Company's  customers
reduced  the number of disks per drive to support the  delivery of lower  priced
disk drives to the rapidly expanding,  low-cost segment of the PC market.  These
customer  actions,  the continuing  imbalance  between the supply and demand for
disk  products,  and the lack of new  data-intensive  applications  continue  to
depress the Company's  financial  performance.  Due to this weak unit demand the
Company  closed the former WDC media  operation at the end of June 1999,  nearly
fifteen months ahead of the Company's original transition plan.

         Disk  industry  conditions  remain very  difficult.  Increased  storage
capacity  per disk is limiting  growth in unit volumes  while excess  production
capacity  within the disk industry  continues to push average selling prices for
disk products lower.  As a result of these negative  industry trends the Company
has reduced its expectations for revenue growth in the immediate future. In July
1999, the Company implemented a reorganization of its U.S. operations which will
result in a reduction  of  approximately  one-third of its U.S.  employees.  The
Company's U.S. operations will focus on activities related to research,  process
development,  product  prototyping,  and pilot  production.  Due to the  revised
expectations for slower growth in unit volumes the Company will be able to shift
production to its  Malaysian  facilities  faster than  previously  planned.  The
Company  expects  that the cost  advantages  of its  Malaysian  facilities  will
improve  its cost  structure  and  ability to respond  to the  continuing  price
pressures for thin-film media.

         As part of its reorganization the Company is consolidating the separate
engineering  and  managerial  staffs  of its  U.S.-based  manufacturing  and R&D
organizations  into a single  organization.  Staff reductions in these functions
and in selling and administrative functions total approximately 500 people. This
work force  reduction,  combined with the June 1999 work force  reduction of 400
people at the former WDC media  operation,  is expected to reduce the employment
base at the Company's U.S.  operations from 1,950 people in April (subsequent to
the  acquisition  of WDC's media  operation)  to 1,050  people by the end of the
third quarter of 1999.  The Company  employs  approximately  2,750 people in its
Malaysian manufacturing operations.  The Company expects to record a significant
charge  in  the  third  quarter  of  1999  for  severance  pay  related  to  the
reorganization  and for the write down of various  assets that will be idled due
to the lower  production  level at its U.S.  operations.  The  Company is in the
process of determining the extent of the charge.

Revenue:

         Net sales  increased to $93.2 million in the second quarter of 1999, up
18% compared to $78.8 million in the second quarter of 1998. The  year-over-year
increase  was due to the net effect of a 41% increase in unit sales volume and a
16% decrease in the overall average selling price.  Net sales in second quarters
of 1999 and 1998  included  $2.2 million and $2.1  million of  substrate  sales,
respectively.  The Company  periodically  sells

                                      -14-

<PAGE>


substrate products but does not currently anticipate that such sales will become
a significant portion of its revenue.  Second quarter 1999 unit sales (excluding
sales of substrate  products)  increased to 11.1 million  disks from 7.8 million
disks in the second quarter of 1998. Unit sales for the second quarter 1998 were
unusually low due to weakened  demand for desktop media products as several disk
drive manufacturers  sharply reduced their desktop product production during the
first half of 1998 in response to supply/demand  imbalances within the industry.
The severe pricing pressures generated by the continuing imbalance in supply and
demand  for  thin-film  media in the  second  quarter  of 1999  resulted  in the
significant  year-over-year  decrease in the overall average selling price.  Net
sales in the first half of 1999 also increased 18% relative to the first half of
1998.  Net sales in first six months of 1999 and 1998  included $6.1 million and
$4.2  million of substrate  sales,  respectively.  Percentage  increases in unit
sales  (excluding  sales of  substrate  products)  and  decreases in the overall
average  selling prices were  comparable to those  percentages  discussed in the
quarterly comparison.

         In addition to sales of internally produced disk products,  the Company
has periodically  resold products  manufactured by its 50%-owned  Japanese joint
venture,  Asahi Komag Co., Ltd.  (AKCL).  Distribution  sales of thin-film media
manufactured  by AKCL were  negligible  in both the  second  quarter of 1999 and
1998.  Distribution sales of these products were negligible in the first half of
1999 and  accounted  for $2.4  million  in the first half of 1998.  The  Company
expects  that  distribution  sales  of  AKCL  product  will be  minimal  for the
remainder of 1999.

         During  the  second  quarter  of  1999  two  customers   accounted  for
approximately 92% of consolidated net sales:  Western Digital  Corporation (74%)
and Maxtor  Corporation  (18%).  The Company  expects  that it will  continue to
derive a substantial  portion of its sales from  relatively few  customers.  The
distribution  of sales among customers may vary from quarter to quarter based on
the  match of the  Company's  product  capabilities  with  specific  disk  drive
programs of customers.  Additionally,  as a result of the April 1999 acquisition
of WDC's media  operation and related volume purchase  agreement,  the Company's
sales remain highly dependent upon WDC's performance in the disk drive industry.

Gross Margin:

         The Company recorded a negative gross margin  percentage of 5.0% in the
second  quarter  of 1999  compared  to a negative  gross  margin of 45.2% in the
second  quarter  of  1998.  The  substantial  improvement  in the  gross  margin
percentage  resulted  from the  combination  of  improvements  in  manufacturing
efficiencies,   higher  unit  production   volumes,   and  reductions  in  fixed
manufacturing  costs.  These favorable  manufacturing  cost reductions more than
offset the 16%  decline in the  overall  average  selling  price.  Manufacturing
efficiency  improvements  included both  improvements  in production  yields and
reductions  in product input costs.  The Company  produced 11.3 million units in
the second  quarter of 1999 compared to 8.9 million units in the second  quarter
of 1998.

                                      -15-

The higher unit production  volume reduced the Company's unit production cost as
fixed costs were spread over more units. Additionally, fixed manufacturing costs
were lower in the second quarter of 1999,  compared to the comparable  period of
1998, as a result of a $175.0 million asset  impairment  charge recorded in June
1998.  The asset  impairment  charge  effectively  reduced  asset  valuations to
reflect the  economic  effect of industry  price  erosion for disk media and the
projected underutilization of the Company's production equipment and facilities.
Due to the reduced asset valuations  depreciation  expense was approximately 27%
lower in the second quarter of 1999 compared to the second quarter of 1998.

         The gross margin improved to a negative 2.1% for the first half of 1999
from a negative 43.4% for the first half of 1998. Unit  production  increased to
21.4 million  disks in the first half of 1999  compared to 15.4 million disks in
the first half of 1998.  The Company  operated well below  capacity in the first
half of 1998 in order to match unit  production  to the sharply lower demand for
its products. Improvements in manufacturing efficiencies, higher unit production
volumes,  and reductions in fixed  manufacturing  costs  favorably  impacted the
Company's gross margin in 1999.  Depreciation  charges in the first half of 1999
were approximately 29% lower than in the first half of 1998 primarily due to the
asset impairment charge recorded in June 1998. The effect of these manufacturing
cost  reductions  more than  offset  the effect of the  decline  in the  overall
average selling price on the Company's gross margin.

Operating Expenses:

         Research and development ("R&D") expenses decreased to $12.2 million in
the second quarter of 1999 from $18.1 million in the second quarter of 1998. R&D
expenses decreased to $24.2 million in the first half of 1999 from $33.0 million
in the  first  half of 1998.  Decreased  R&D  staffing  and lower  facility  and
equipment costs (primarily due to the 1998 impairment charge) accounted for most
of the  decrease  in R&D  expenses in both the three- and  six-month  periods of
1999.  Selling,  general and administrative  ("SG&A") expenses increased to $5.6
million in the second quarter of 1999 from $4.9 million in the second quarter of
1998.  SG&A  expenses  increased to $11.1 million in the first half of 1999 from
$9.6 million in the first half of 1998.  The  increases  for both the three- and
six-month  periods of 1999 were  primarily due to higher bad debt  provisions in
the three- and six-month  periods of 1999 relative to the comparable  periods of
1998.  Excluding provisions for bad debt, SG&A expenses increased less than $0.1
million in both the three- and six-month  periods of 1999 compared to the three-
and six-month periods of 1998.

Goodwill Amortization:

         The Company's  acquisition of WDC's media operation was recorded in the
second quarter of 1999 as a business  combination  using the purchase  method of

         The Company  recognized  goodwill and other  intangibles  in connection
with the  acquisition of the WDC media operation in the amount of $83.9 million.
Goodwill  typically reflects the difference between the fair value of the assets
acquired and  consideration  paid.  Under purchase  accounting rules the Company
also recorded  liabilities  that  increased  the amount of goodwill  recognized.
These  liabilities  included  estimated  costs for the closure of the former WDC
media operation as well as costs related to the remaining lease  obligations for
equipment taken out of service due to the closure. The Company is amortizing the
goodwill over the three-year  life that coincides with the term of the Company's
volume purchase agreement with WDC.

         During the second quarter of 1999 the Company paid  approximately  $2.9
million against theses  liabilities  primarily for equipment  lease  obligations
($2.4 million) and other liabilities ($0.5 million). Equipment lease obligations
are expected to be paid monthly  through  mid-2002.  At July 4, 1999 the current
portion of the equipment  lease  obligations  was  approximately  $10.3 million.
Facility closure costs,  purchase order cancellation costs and other liabilities
associated with the WDC transaction are expected

                                      -17-

to be paid by mid-2000.

Restructuring Charge:

         The  Company  recorded  restructuring  charges  of $4.3  million in the
second  quarter of 1999 and $187.8  million in the second  quarter of 1998.  The
1999  restructuring  charge primarily  related to the severance of approximately
400 employees. Approximately $3.4 million was paid to these employees during the
second  quarter of 1999 and the  remaining  $0.9  million is expected to be paid
during  the third  quarter  of 1999.  The 1998  restructuring  charge  consisted
primarily  of a  $175.0  million  non-cash  asset  impairment  charge.  The cash
component  of the 1998 charge was $12.8  million for employee  severance  costs,
equipment order cancellations costs, and facility closure costs.

Interest and Other Income/Expense:

         Interest  income  decreased  $1.0 million in the second quarter of 1999
relative  to the second  quarter  of 1998 and $2.0  million in the first half of
1999 relative to the first half of 1998 due to lower average cash and short-term
investment balances in the current year periods. Interest expense increased $1.2
million in the second quarter of 1999 compared to the second quarter of 1998 and
increased  $1.6 million in the first half of 1999  compared to the first half of
1998. The increases for both the three- and six-month periods were primarily due
to an additional  $0.9 million in interest  expense  under the  Company's  $21.2
million note payable to WDC in connection  with the  acquisition  of WDC's media
operation.  The  note  payable  to WDC  has  been  discounted  to the  Company's
estimated  incremental  borrowing rate of 18% for subordinated debt instruments.
Other income  increased  $1.3 million in the second  quarter of 1999 compared to
the second  quarter of 1998.  The increase was  primarily due to lower losses on
disposals  of  property,  plant and  equipment  in the  second  quarter  of 1999
compared to the second quarter of 1998.  Other income  decreased $2.4 million in
the first half of 1999 relative to the first half of 1998. Other income in first
half of 1998  included a $3.1 million gain on the March 1998 sale of vacant land
located in Milpitas, California.

Income Taxes:

         The Company's income tax provision was  approximately  $0.4 million and
$0.8  million  for the  three-  and  six-month  periods  of 1999,  respectively,
compared to $0.7 million for both the three- and six-month  periods of 1998. The
income tax provisions for both the 1999 and 1998 periods  primarily  represented
foreign withholding taxes. The Company's wholly-owned thin-film media operation,
Komag  USA  (Malaysia)  Sdn.  ("KMS"),  received  an  extension  of its  initial
five-year tax holiday for an additional five years  commencing in July 1998. KMS
has also been  granted a ten-year  tax  holiday  for its second and third  plant
sites in Malaysia.  The commencement  date for this new tax holiday has not been
determined as of August 4, 1999.

Minority Interest in KMT/Equity in Net Income (Loss) of AKCL:

         The  minority  interest  in the net income of  consolidated  subsidiary
represented

                                      -18-

<PAGE>


Kobe  Steel USA  Holdings  Inc.'s  ("Kobe  USA's")  20% share of Komag  Material
Technology, Inc.'s ("KMT's") net income. KMT recorded net income of $0.4 million
and $1.7  million in the second  quarter  and first half of 1999,  respectively,
compared to $3.0 million and $2.5  million in the second  quarter and first half
of 1998, respectively.

         The Company owns a 50% interest in AKCL and records its share of AKCL's
net  income  (loss) as  equity in net  income  (loss)  of  unconsolidated  joint
venture. During the first three months of 1999, the Company's investment in AKCL
was reduced to zero as a result of recording a portion of the Company's share of
AKCL's losses for the first quarter of 1999.  Approximately  $0.6 million of the
Company's  share of AKCL's first  quarter loss was not recorded as it would have
reduced the net book value of the  investment in AKCL below zero.  AKCL recorded
net income of $0.3 million for the second  quarter of 1999.  The Company has not
recorded its share of this income as the Company's cumulative  unrecorded equity
in AKCL is a loss of  approximately  $0.4  million.  Assuming  AKCL  reports net
income in future periods,  the Company will record its share of such income only
to the extent by which the income exceeds the losses incurred  subsequent to the
date on which the investment balance became zero.

Year 2000 Issue:

         Many computer systems were not designed to properly handle dates beyond
the year 1999.  Such systems were designed  using two digits rather than four to
define the  applicable  year.  Any computer  programs  that have  time-sensitive
software  may  recognize a date using "00" as the year 1900 rather than the year
2000.  This  could  result  in  a  system  failure  or  miscalculations  causing
disruptions  of  operations.  Disruptions  may also  occur if key  suppliers  or
customers  experience  disruptions in their ability to transact with the Company
due to Year 2000 issues.  The Company's  global  operations  rely heavily on the
infrastructures  of the countries in which it conducts  business.  The Year 2000
readiness within infrastructure  suppliers (utilities,  government agencies such
as customs, shipping organizations) will be critical to the Company's ability to
avoid  disruption of its operations.  The Company is working with industry trade
associations  to evaluate the Year 2000 readiness of  infrastructure  suppliers.
The Company has completed  the  assessment  phase of its Year 2000 program.  The
Company has committed  personnel and  resources to resolve  potential  Year 2000
issues and is working with key suppliers and customers to ensure their Year 2000
readiness.

         The  Company's  Year 2000 efforts are focused on three primary areas of
potential  impact:  internal  information  technology  ("IT") systems,  internal
non-IT  systems,  and the  readiness of third  parties with whom the Company has
critical  business  relationships.  Testing and  remediation  of internal IT and
non-IT systems is  approximately  90% complete.  The Company expects to complete
the testing and remediation for these systems by October 1, 1999.

         The Company has developed a process for  identifying and assessing Year
2000

                                      -19-

<PAGE>


readiness  of its  critical  suppliers.  This  process  generally  involves  the
following  steps:  initial  supplier  survey,  follow-up  supplier  review,  and
contingency  planning.  The Company is following up with critical suppliers that
either did not respond  initially or whose  responses  were  unsatisfactory.  To
date,  the  Company  has  received  responses  from a majority  of its  critical
suppliers,  most of whom have responded that they expect to address all of their
significant Year 2000 issues on a timely basis.

         Remediation  costs of the Year 2000 issue have not been material to the
Company's  results  of  operations  or  financial  position.   The  Company  has
cumulatively  incurred  remediation  costs of  approximately  $0.5 million.  The
Company does not separately  track the internal costs incurred for the Year 2000
project  (primarily the payroll cost for its information  systems group).  While
the Company currently expects that the Year 2000 issue will not pose significant
operational  problems, a failure to fully identify all Year 2000 dependencies in
the  Company's  systems  and in the  systems  of its  suppliers,  customers  and
financial  institutions  could have  material  adverse  consequences,  including
delays  in the  delivery  or  sales  of  products.  Therefore,  the  Company  is
developing  contingency  plans  for  continuing  operations  in the  event  such
problems arise.  These contingency plans are expected to be completed by October
1, 1999.

         The  Company is working to identify  and  analyze  the most  reasonably
likely  worst-case  scenarios  where it may be  affected  by Year  2000  related
interruptions.  These scenarios could include possible infrastructure  collapse,
the  failure  of power and water  supplies,  major  transportation  disruptions,
unforeseen  product  shortages  due to hoarding of material  and  supplies,  and
failures of  communications  and financial  systems.  Any one of these scenarios
could have a major and material  effect on the Company's  ability to produce and
deliver products to its customers.  While the Company is developing  contingency
plans to address issues under its control, an infrastructure  problem outside of
its control or some  combination  of several of these problems could result in a
delay in product shipments depending on the nature and severity of the problems.
The Company would expect that most utilities and service providers would be able
to restore service within days although more pervasive system problems involving
multiple  providers  could  last  several  weeks  or  longer  depending  on  the
complexity of the systems and the effectiveness of their contingency plans.

         The Company's products are not date sensitive. Additionally, disk drive
manufacturers  have generally  stated that disk drives as a stand-alone  product
are not date sensitive.  The Company expects that it will have limited  exposure
to product liability litigation resulting from Year 2000 related failures.

Liquidity and Capital Resources:

         Cash and  short-term  investments  of $94.5  million  at the end of the
second quarter of 1999 decreased  $33.3 million from the end of the prior fiscal
year.  Working capital  decreased $35.7 million from the end of the prior fiscal
year.  Consolidated  operating  activities consumed $18.0 million in cash during
the first half of 1999.  The $59.8 million  operating loss for the first half of
1999, net of non-cash  depreciation and  amortization  charges of $56.0 million,
the non-cash  equity loss from AKCL of $1.4 million and other  non-cash/deferred
charges  totaling $1.9 million,  used $0.5 million.  Changes in operating assets
and  liabilities  used $17.5  million.  Increases  in  accounts  receivable  and
inventories  each  consumed  $8.5  million.  The Company  spent $17.6 million on
capital  requirements during the first half of 1999. Sales of Common Stock under
the Company's stock programs generated $2.3 million.

         Total  capital   expenditures   for  1999  are  currently   planned  at
approximately  $40 million.  Current  noncancellable  capital  commitments total
approximately  $5  million.  In  light  of the  continuing  weak  disk  industry
conditions  the Company  plans to closely  monitor its capital needs in order to
limit capital spending for the last half of 1999 and future periods. The size of
the  Company's  second  quarter of 1998 net loss has resulted in a default under
certain  financial  covenants  contained  in the  Company's  various bank credit
facilities.  The Company currently has $260 million of unsecured bank borrowings
outstanding.  No additional  borrowing  capacity is available as a result of the
technical default. The Company is not in payment default under any of its credit
facilities. The Company is currently negotiating with its lenders for amendments
to the  existing  credit  facilities.  The  Company's  ability  to  successfully
conclude these negotiations has been delayed during the past year as a result of
changes in the Company's  business  model due to the  acquisition of WDC's media
facility and  continuing  deterioration  in the disk  industry.  There can be no
assurance that the Company will be able to obtain such  amendments to its credit
facilities  on   commercially   reasonable   terms.  If  the  Company  does  not
successfully amend these credit facilities, it would remain in technical default
of its bank loans and the lenders  would retain their rights and remedies  under
the existing credit agreements.  As long as the lenders choose not to accelerate
any principal payments, the Company would continue to operate in default for the
near term.  However,  the Company will likely need to raise  additional funds to
restructure its debt obligations and to operate its business for the long term.

         There can be no assurance  that the Company will be able to secure such
financial  resources on commercially  reasonable terms. If the Company is unable
to obtain adequate  financing,  it could be required to significantly  reduce or
possibly suspend its operations,  and/or to sell additional  securities on terms
that would be highly dilutive to current stockholders.

                           (ii) The  Company  represents  and  warrants to Komag
that the Signing NBV  Statement  has been prepared from the books and records of
the Company in accordance with GAAP,  consistent with the accounting  principles
used in the preparation of the Company's  annual audited  financial  statements.
The Company has, and has requested its internal  accountants  to, make available
to Komag and its accountants  copies of all customary  accounting and other work
papers in their respective  possession that were prepared in connection with the
preparation of the Signing NBV Statement.

                           (iii) On the Closing Date,  the Company shall deliver
to Komag an updated version of the Signing NBV Statement  ("Preliminary  Closing
NBV Statement") setting forth the items identified in subsection (b)(i) above as
of the Closing Date including  calculation of the AA Net Book Value ("Closing AA
Net Book Value") and the Cash Prepaid  Assets Net Book Value  ("Closing  CPA Net
Book Value"),  revised in each case, if appropriate,  to include any adjustments
agreed upon between the Parties since the date of the Signing NBV Statement. The
Preliminary  Closing NBV Statement shall be accompanied by a certificate  signed
by a duly  authorized  officer of the Company  certifying as to the accuracy and
completeness  of the  Preliminary  Closing NBV Statement as of the Closing Date.
The  Preliminary  Closing NBV  Statement  shall be  prepared  from the books and
records of the Company in accordance  with GAAP,  consistent with the accounting
principles  used in the  preparation of the Company's  annual audited  financial
statements. The Company will, and will request its internal accountants to, make
available to Komag and its  accountants  copies of all customary  accounting and
other  work  papers  in  their  respective  possession  that  were  prepared  in
connection with the preparation of the Preliminary Closing NBV Statement.

                           (iv) Within thirty (30)  calendar days  following the
Closing,  the Company  shall  submit to Komag in writing any and all changes and
adjustments  to the  Preliminary  Closing  NBV  Statement  necessary  to reflect
properly  the actual AA Net Book Value and the Closing  Prepaid  Assets Net Book
Value, each as of the Closing Date (the "Final Closing NBV Statement"),  revised
in each case, if appropriate, to include any adjustments agreed upon between the
Parties since the date of the Preliminary Closing NBV Statement, together with a
special  purpose report  prepared by the Company's  outside  auditors  ("Outside
Auditors")  which shall confirm that the  calculations  of the AA Net Book Value
and the Closing CPA Net Book Value set forth on the Final  Closing NBV Statement
have been  accurately  derived  from,  and tied to, the books and records of the
Company ("Special Purpose Report"). In preparing the Special Purpose Report, the
Outside  Auditors shall use the procedures set forth in that certain letter (the
"Auditors'  Letter")  from the Outside  Auditors  to the Company  dated April 8,
1999,  a copy of which has been  provided  to  Komag.  The  reasonable  fees and
expenses of the Outside Auditors shall be borne by Komag. The revision of the AA
Net Book Value or the Closing CPA Net Book Value,  as  applicable,  set forth on
the Final Closing NBV Statement  shall be deemed the "Revised AA Net Book Value"
or the "Revised CPA Net Book Value", as applicable.

                  (c)  Determination  of Cash  Prepaid  Assets  Net Book  Value;
Adjustment to Cash Portion of Purchase  Price.  The Cash Prepaid Assets Net Book
Value  utilized  in  calculating  the  amount of cash to be paid by Komag to the
Company  following  the  Closing  shall be deemed to be the Closing CPA Net Book
Value; provided that, following the Closing, if the Cash Prepaid Assets

Net Book  Value is  revised  pursuant  to  Sections  2.3(b)(iv)  hereof and such
Revised CPA Net Book Value is less than the Closing CPA Net Book Value, then the
Company shall  promptly,  and in no event more than ten (10) business days after
providing Komag the Final Closing NBV Statement,  pay to Komag an amount in cash
equal to the  difference  between the Closing CPA Net Book Value and the Revised
CPA Net Book Value. No adjustment to the cash portion of the purchase price will
be made if the  Revised  CPA Net Book  Value is  equal  to or  greater  than the
Closing CPA Net Book Value.

                  (d)  Acknowledgment  regarding AA Net Book Value.  The Parties
acknowledge  and agree that the AA Net Book Value and  Closing AA Net Book Value
set  forth  on  the  Signing  NBV  Statement  and  the  Closing  NBV  Statement,
respectively, were utilized to determine the portion of the Purchase Price to be
paid in consideration  for the Acquired Assets (excluding the Finished Goods and
Cash  Prepaid  Assets),  which  the  Parties  acknowledge  to  be  approximately
$65,000,000.  The Parties  further  acknowledge and agree that, if the actual AA
Net Book Value is less than  $65,000,000,  Komag will have  suffered  damages or
losses for which Komag is entitled to seek  indemnification  pursuant to Article
VIII of this  Agreement in such amount that the actual AA Net Book Value is less
than the $65,000,000.

         2.4 Transfer Taxes. Komag shall pay and promptly discharge when due any
and all Sales Taxes that may become  payable by reason of or in connection  with
the  Acquisition;  provided that the Company shall use  commercially  reasonable
efforts to assist  Komag in  minimizing  any  Liability  for such Sales Tax. The
amount of Sales Tax  collectible  from Komag by the Company  shall be reduced by
the amount of the  deduction  to which the  Company is  entitled  for  "Tax-paid
purchases  resold"  as defined in its  California  Sales and Use Tax  Regulation
Section 1707, with respect to the Acquired  Assets.  The Company and Komag shall
prorate  between them (a) secured and unsecured  property  Taxes on all Acquired
Assets, (b) sewer and water rentals and utility charges applicable to the Leased
Real Property ("Utility Charges") and (c) rentals, fees, assessments and similar
charges with respect to the agreements, contracts, licenses and permits included
in the Acquired Assets ("Rental Fees"). In the case of taxable or other relevant
payment  periods  commencing  on or before the Closing Date and ending after the
Closing Date, secured and unsecured  property Taxes,  Utility Charges and Rental
Fees  which  relate to any  period on or before  the  Closing  Date or after the
Closing Date, as  applicable,  shall be in the case of Utility  Charges,  Rental
Fees and secured and unsecured property Taxes (that are not based on net income,
gross  income,  sales,  premiums or gross  receipts),  the total  amount of such
Utility  Charges,  Rental Fees and secured and unsecured Taxes for the period in
question multiplied by a fraction,  the numerator of which is the number of days
in the portion of such period  through the Closing Date or after such date,  and
the denominator of which is the total number of days in such period.

         2.5 The Closing.

                  (a) Closing.  The closing of the transactions  contemplated by
this Agreement (the "Closing") shall take place at the offices of Wilson Sonsini
Goodrich & Rosati, Professional Corporation, in Palo Alto, California commencing

waiver of all  conditions to the  obligations  of the Parties to consummate

the  transactions  contemplated  hereby (other than  conditions  with respect to
actions the  respective  Parties will take at the Closing  itself) or such other
date as the Parties may mutually determine (the "Closing Date").

                  (b) Deliveries at the Closing. At the Closing, (i) the Company
will  deliver  to Komag the  various  certificates,  instruments  and  documents
referred  to  in  Section  7.2  below  and  will  execute  and  acknowledge  (if
appropriate) and deliver such other  instruments of sale,  transfer,  conveyance
and assignment as Komag and its counsel may reasonably request;  (ii) Komag will
deliver to the Company  the  various  certificates,  instruments  and  documents
referred  to  in  Section  7.3  below  and  will  execute  and  acknowledge  (if
appropriate) and deliver such other instruments of assumption as the Company and
its counsel may reasonably request;  and (iii) Komag will deliver to the Company
stock  certificates  representing  the Sale Shares in the amount  determined  in
accordance with Section 2.3 above.

         2.6 Taking of Necessary Action;  Further Action.  If, at any time after
the Closing Date,  any further action is necessary or desirable to carry out the
purposes  of this  Agreement  and to vest  Komag  with  full  right,  title  and
possession to the Acquired Assets, the officers and directors of the Company are
fully  authorized  in the name the Company or otherwise to take,  and will take,
all such lawful and necessary and/or desirable action.

         2.7 Nonassignability and Consents.

                  (a) To the extent that any asset which would  otherwise  be an
Acquired Asset, or any claim,  right or benefit arising  thereunder or resulting
therefrom,  is not capable of being sold,  conveyed,  assigned,  transferred  or
delivered  without the approval,  consent or waiver of any Person (including any
Governmental  Entity)  other  than the  Company,  or if such  sale,  conveyance,
assignment,  transfer or delivery or  attempted  sale,  conveyance,  assignment,
transfer or delivery would constitute a breach or termination right thereof or a
violation of any law, decree,  order,  regulation or other  governmental  edict,
except  as  expressly  otherwise  provided  herein,  this  Agreement  shall  not
constitute a sale, conveyance,  assignment,  transfer or delivery thereof, or an
attempted sale, conveyance,  assignment,  transfer or delivery thereof. Any such
assets shall be a "Non-Transferable Asset."

                  (b) The  Company  shall  not be  obligated  to  sell,  assign,
transfer,  convey  or  deliver,  or  cause to be  sold,  assigned,  transferred,
conveyed or delivered,  to Komag,  and Komag shall not be obligated to purchase,
any  Non-Transferable  Asset  without first having  obtained all such  consents,
approvals  or  waivers or removed or  eliminated  any such  potential  breach or
termination  of  any  contract,  agreement  or  other  instrument  or  potential
violation of any law, decree, order,  regulation or other governmental edict. To
the extent that at the Closing there are any  Non-Transferable  Assets, from and
after the Closing,  the Parties will  cooperate,  at the Company's  expense,  to
effect a lawful and  mutually  acceptable  arrangement  under  which Komag would
obtain the benefit of such  Non-Transferable  Asset,  including  subcontracting,
sub-licensing,  or sub-leasing such Non-Transferable  Asset to Komag, and Komag,
so long as such benefit is so provided, would satisfy or perform any Liabilities
or obligations under or in connection with such Non-Transferable Asset which may
arise

following the Closing which would not otherwise be a Retained  Liability if such
Non-Transferable  Asset were an Acquired Asset. From and after the Closing Date,
the Company will promptly pay to Komag when received all monies  received by the
Company  under any Acquired  Asset or any claim or right or any benefit  arising
thereunder,  except  to the  extent  the  same  represents  an  Excluded  Asset.
Notwithstanding  the foregoing,  nothing contained herein shall in anyway affect
the rights or  obligations  of the Parties under that certain  Escrow  Agreement
dated February 19, 1999 ("Escrow Agreement") with respect to the distribution of
the Property (as defined therein) in accordance with the terms thereof.

                  (c) At any time after Closing, if any  Non-Transferable  Asset
becomes capable of being sold, assigned,  transferred,  conveyed or delivered to
Komag, or if the benefit can be provided to Komag without the required  consent,
approval or waiver of any third party, and if such sale,  assignment,  transfer,
conveyance or delivery,  or the provision of such benefit would not constitute a
breach  or  termination  of any  agreement,  contract  or  other  instrument  or
violation of law, decree,  order,  regulation or other governmental edict, then,
at such time, the Company shall sell,  assign,  transfer,  convey and deliver to
Komag or cause to be sold,  assigned,  transferred,  conveyed  and  delivered to
Komag,  or provide to Komag the  benefit of such asset and,  if such asset is an
agreement,  contract,  instrument,  license or permit,  Komag  shall  assume the
Liabilities  and  obligations  of the  Company  thereunder  to the  extent  such
Liabilities  and  obligations  arise  from  the  performance  of the  agreement,
contract,  instrument,  license or permit from and after the  effective  date of
such assignment and to the extent such  Liabilities  and  obligations  would not
otherwise  be  Retained  Liabilities  if  such  Non-Transferable  Asset  were an
Acquired Asset.

                  (d)  Notwithstanding  anything  contained in this Agreement to
the  contrary,  in  addition  to (and not in lieu of) any of the  other  rights,
remedies and  obligations  of the Parties  hereunder,  (i) in the event that the
Company is unable to obtain  prior to the Closing any of the  consents,  waivers
and approval  referenced in Section 6.5 of this  Agreement  (including,  without
limitation, under any contracts set forth in Section 3.4, 3.5, 3.10(b), 3.10(c),
3.11(a)(ii),  3.12(a) and 3.14 of the Company Disclosure  Schedules) as required
pursuant to this Agreement, the Company shall, within thirty (30) days following
the Closing Date, obtain all such consents,  waivers and approvals,  in form and
substance reasonably  acceptable to Komag and (ii) in the event that the Company
is unable to discharge or remove prior to the Closing any of the Liens set forth
in Section 1.1(a) of the Company  Disclosure  Schedules as required  pursuant to
this Agreement, the Company shall, within thirty (30) days following the Closing
Date,  have all such Liens  discharged  and/or  removed  in a manner  reasonably
acceptable to Komag.

the  Company  and  Komag,  respectively,  contained  in  this  Agreement  to  be
materially   untrue  or  inaccurate  at  or  prior  to  the  Closing  except  as
contemplated by this Agreement  (including the Company Disclosure  Schedule) and
(ii) any failure of the Company or Komag,  as the case may be, to comply with or
satisfy in any  material  respect any  covenant,  condition  or  agreement to be
complied with or satisfied by it hereunder; provided, however, that the delivery
of any notice  pursuant to this Section 6.7 shall not limit or otherwise  affect
any remedies available to the party receiving such notice.

         6.8 Employee Matters.

                  (a) Selection of Employees. Komag has made, and is prepared to
make further,  written offers of employment to those  Employees at the Company's
Santa  Clara,  California  and San Jose,  California  facilities  as Komag deems
necessary,  in its sole  discretion,  to operate the Media Business  efficiently
after the Closing and to meet the Company's volume requirements set forth in the
Volume Purchase  Agreement  (conditional  upon the closing of the  Acquisition);
provided,  that  Komag  shall not be  obligated  to  employ,  and shall  have no
Liability with respect to the continued employment of, any of the Employees. The
Company  hereby  waives,  releases and discharges all Employees who shall accept
employment from Komag ("Transferred Employees") from any and all noncompetition,
confidentiality  or employment  restrictions,  obligations or agreements entered
into by such  Transferred  Employees  with the  Company to the extent  that such
Transferred  Employees are performing services related to the Media Business for
Komag or any of its  Affiliates.  The  Company  agrees  that any  disclosure  of
confidential  information  relating  to  the  Media  Business  by a  Transferred
Employee to Komag or any of its Affiliates  shall not constitute a breach of any
confidentiality agreement between such Transferred Employee and the Company.

                  (b)  Employee   Plans.   Komag  shall  use  all   commercially
reasonable efforts to (i) provide all Transferred Employees with employee health
benefits  substantially  similar in the aggregate in coverage and benefits as to
those provided as of the date hereof by the Company, (ii) waive any pre-existing
condition  requirements  or waiting  period  requirements  under  such  Person's
Employee Plans to the extent  permitted by the insurance  carrier,  (iii) credit
previous  service  by the  Transferred  Employees  with the  Company  under such
Person's  comparable  employee  benefit  plans,  including  but not limited to a
401(k)  savings  plan,  for  purposes  of  eligibility  to  participate,   early
commencement  of  benefits  and  vesting  and (iv) apply  toward any  deductible
requirement or  "out-of-pocket"  maximum limit under any such Person's  employee
benefit plans any amounts paid (or accrued) by each  Transferred  Employee under
any  Employee  Plan,  to the  extent  that the plan years of the  relevant  plan
overlap.

                  (c) 401(k) Plan Rollovers.  The Company and Komag agree to use
their best  efforts to enable  individual  rollovers of  Transferred  Employees'
account  balances in the  Company's  401(k) Plan to Komag's  401(k) Plan,  which
balances may include plan loans.  In  furtherance  and not in  limitation of the
foregoing,  provided that  Transferred  Employees  have  completed the Company's
401(k) termination distribution request form, the Company shall complete Komag's
standard rollover form for each Transferred Employee electing to rollover his or
her account  balance into Komag's 401(k) Plan in a timely  manner.  In addition,
the Company will provide Komag with a

discussion of facts in support of the Company's  view that the sale of the Media
Business  by the  Company  to  Komag is the  sale of  "substantially  all of the
assets" used in a "trade or business"  within the meaning of section  401(k)(10)
of the Code.

                  (d) WARN Act. The Company has sent out a notification pursuant
to the Workers  Adjustment and Retraining  Notification  Act of 1988, as amended
("WARN  Act"),  to all  Employees  who are not Offered  Employees  ("Non-Offered
Employees") to commence the sixty (60) day  notification  period  required under
the WARN  Act.  All  Liabilities  relating  to the  employment,  termination  or
employee benefits of Employees  including,  without limitation,  all termination
obligations in connection with the WARN Act shall be the  responsibility  of the
Company;  provided  that Komag  shall be  responsible  for all such  termination
obligations under the WARN Act with respect to (i) Employees who were designated
as Offered  Employees  by Komag but whose offers of  employment  were revoked by
Komag  prior to the Closing and (ii)  Offered  Employees  who are hired by Komag
following  the Closing to the extent such  obligations  under the WARN Act arise
from actions of Komag following the Closing;  provided,  further,  however, that
Komag shall not be responsible  for termination  obligations  under the WARN Act
with respect to Offered  Employees who do not accept  offers of employment  from
Komag.  In addition,  the Company shall give advance  notice to all  Non-Offered
Employees under any state statute analogous to the WARN Act.

                  (e)  COBRA.  The  Company  shall  be  solely  responsible  for
providing  continuation  health  coverage,  to the  extent  required  under  the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), to
all Offered and  Non-Offered  Employees and their  eligible  dependents who have
experienced  a qualifying  event before or on the Closing Date and who (i) elect
continuation  coverage  within the time period  prescribed by COBRA and (ii) who
are otherwise qualified  beneficiaries (as defined in Section 4980B(g)(1) of the
Code),  and the  Company  shall  indemnify  Komag for any and all loss,  cost or
expense relating to any and all outstanding obligations,  Liabilities and claims
arising under COBRA.

                  (f)  Nonsolicitation  of Employees.  Notwithstanding  anything
else contained  herein to the contrary,  (a) unless this Agreement is terminated
prior to the Closing for any reason, the Company shall not solicit the continued
employment  of any of the  Transferred  Employees  for a period of  twelve  (12)
months following the date Komag  designated such Employees as Offered  Employees
and (b) in the event that this Agreement is terminated  prior to Closing for any
reason, Komag shall not continue to solicit the employment of any of the Offered
Employees  for a  period  of  twelve  (12)  months  following  the  date  of the
termination of the Agreement;  provided that, the foregoing  restrictions  shall
not prohibit any of the parties from making general  solicitations of employment
not specifically directed to the Employees.

                  (g)  No  Third  Party  Beneficiary   Rights.   Notwithstanding
anything  contained  herein to the  contrary,  no  provision in this Section 6.8
shall  create  any third  party  beneficiary  or other  rights  to any  Employee
(including  any  beneficiary  or  dependent  thereof)  in respect  of  continued
employment  (or  resumed  employment)  with the  Company,  Komag or any of their
Affiliates,  and no provision in this Section 6.8 shall create any rights in any
such  Person in  respect  of any  benefits  that may be  provided,  directly  or
indirectly, under any Employee Plan or arrangement

                                  ARTICLE VIII

          SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW; INDEMNITY

         8.1 Survival of Representations and Warranties.  Except as set forth in
Section 8.5 hereof, all of the  representations and warranties in this Agreement
or in any  certificate  delivered  pursuant to this Agreement  shall survive the
Acquisition  and continue for a period  ending on the [***]  anniversary  of the
Closing.

         8.2 Agreement to Indemnify.

                  (a) The Company agrees to indemnify and hold Komag and each of
its Affiliates,  officers, directors,  employees and shareholders (collectively,
the "Komag Indemnitees") harmless against any and all losses,  claims,  damages,
costs,  expenses or other liabilities  (including reasonable attorneys' fees and
expenses and expenses of investigation  and defense)  (collectively,  "Damages")
resulting  from (i) any  breach  of or  inaccuracy  in any  representations  and
warranties of the Company set forth in this  Agreement,  the Company  Disclosure
Schedule or in any other  certificate  delivered  by or on behalf of the Company
pursuant  to this  Agreement,  (ii) any breach or default by the  Company of any
covenant,  obligation  or  other  agreement  of the  Company  set  forth in this
Agreement, the Company Disclosure Schedule or any other certificate delivered by
or on behalf of the  Company  pursuant  to this  Agreement  and (iii) any of the
Retained Liabilities (each, a "Komag Indemnifiable Claim").

                  (b) Komag agrees to indemnify and hold the Company and each of
its Affiliates,  officers, directors,  employees and shareholders (collectively,
the "Company  Indemnitees")  harmless against any and all Damages resulting from
(i) any breach of or inaccuracy in any  representations  and warranties of Komag
set forth in this  Agreement,  the  Komag  Disclosure  Schedule  or in any other
certificate delivered by or on behalf of

the Company  pursuant to this Agreement,  (ii) any breach or default by Komag of
any  covenant,  obligation  or  other  agreement  of  Komag  set  forth  in this
Agreement,  the Komag Disclosure Schedule, or any other certificate delivered by
or on behalf of the  Company  pursuant  to this  Agreement  and (iii) any of the
Assumed Liabilities (each, a "Company Indemnifiable Claim").

         8.3 Limits of  Liability.  In no event  shall any Komag  Indemnitee  or
Company Indemnitee, as applicable ("Indemnitee"),  be reimbursed for any Damages
under this Article VIII until the aggregate of all Damages incurred by all Komag
Indemnitees  or  Company  Indemnitees,  as  the  case  may  be,  exceeds  $[***]
("Threshold  Amount")  (after  which the amount of all Damages,  including  such
$[***],  shall become payable in accordance  with the provisions of this Article
VIII);  provided that, (i) the Threshold Amount shall not apply to [***] or (ii)
the  Threshold  Amount shall not apply to [***].  Notwithstanding  anything else
contained in this Agreement to the contrary,  the maximum aggregate amount which
Komag  Indemnitees or the Company  Indemnitees,  as the case may be, may recover
pursuant to this Article VIII is $[***]; provided that, the indemnities provided
in Sections  8.2(a)(iii) and  8.2(b)(iii)  shall not be limited by the foregoing
$[***] maximum.

         8.4 Indemnification Procedures; Time Limits.

                  (a) If any Indemnitee shall incur any Damages,  there shall be
delivered  to the  Company  or  Komag,  as the  case  may be (the  "Indemnifying
Party"), a certificate signed in good faith by the Company or Komag, as the case
may be, on behalf of such Indemnitee (an "Officer's  Certificate")  stating that
such Indemnitee has paid,  properly  accrued or reasonably  anticipates  that it
will have to pay or accrue  Damages  in an amount  specified  in such  Officer's
Certificate,  specifying in reasonable  detail the  individual  items of Damages
included  in the amount so stated,  the date each such item was paid or properly
accrued,  or the basis for such anticipated  Liability,  and the nature of Komag
Indemnifiable  Claim or  Company  Indemnifiable  Claim,  as the case may be (the
"Indemnifiable  Claim"),  to which such item is related.  The Indemnifying Party
shall,  within  thirty  (30) days after  receipt of the  Officer's  Certificate,
subject to the provisions of Section 8.4(c) hereof,  deliver to such  Indemnitee
in immediately available funds (U.S. Dollars) an amount equal to such Damages.

                  (b) For a period of thirty (30) days after the receipt of such
Officer's Certificate by the Indemnifying Party, the Indemnifying Party shall be
entitled to review the Officer's  Certificate and the basis of the Indemnifiable
Claim. If the Indemnifying  Party desires to dispute the Indemnifiable  Claim or
the Damages set forth in the Officer's  Certificate,  the Indemnifying Party may
do so by providing  written  notice of such dispute to the Company or Komag,  as
the case may be, on behalf of the  Indemnitee  prior to the  expiration  of such
thirty (30) day period.

                  (c) If the  Indemnifying  Party  shall so object in writing to
any claim or claims made in any Officer's  Certificate,  the Indemnifying  Party
and the Company or Komag, as the case may be, on behalf of the Indemnitee  shall
attempt in good faith to agree upon the rights of the  respective  parties  with
respect to each of such  claims.  If the  Indemnifying  Party and the Company or
Komag,  as the case may be,  on  behalf of the  Indemnitee,  should so agree,  a
memorandum  setting forth such agreement  shall be prepared and signed by Komag,
the Company and the  Indemnitee  and the  parties  shall  resolve the dispute in
accordance with such memorandum.  If no such agreement can be reached after good
faith negotiation, either the Indemnifying Party or the Company or Komag, as

the case may be, on behalf of the  Indemnitee,  may  demand  arbitration  of the
matter unless the amount of the damage or loss is at issue in pending litigation
with a third party, in which event arbitration shall not be commenced until such
amount is ascertained or the Indemnifying Party and Komag or the Company, as the
case may be, on behalf of the Indemnitee,  agree to  arbitration;  and in either
such  event the  matter  shall be  settled  by  arbitration  conducted  by three
arbitrators.  The Indemnifying  Party and Komag or the Company,  as the case may
be, on behalf of the Indemnitee,  shall each select one arbitrator,  and the two
arbitrators  so  selected  shall  select  a  third  arbitrator,  each  of  which
arbitrators  shall be  independent.  The  arbitrators  shall set a limited  time
period  and  establish  procedures  designed  to  reduce  the  cost and time for
discovery  while  allowing  the  parties an  opportunity,  adequate  in the sole
judgment of the arbitrators,  to discover relevant information from the opposing
parties about the subject matter of the dispute. The arbitrators shall rule upon
motions  to compel or limit  discovery  and shall have the  authority  to impose
sanctions,  including  attorneys  fees and  costs,  to the  extent as a court of
competent law or equity,  should the  arbitrators  determine  that discovery was
sought  without  substantial  justification  or that  discovery  was  refused or
objected to without substantial justification. The decision of a majority of the
three  arbitrators  as to the validity and amount of any claim in such Officer's
Certificate  shall be binding and conclusive  upon the parties to this Agreement
and all other Indemnitees. Such decision shall be written and shall be supported
by written  findings  of fact and  conclusions  which shall set forth the award,
judgment, decree or order awarded by the arbitrators.

                  (d) Judgment upon any award rendered by the arbitrators may be
entered in any court having jurisdiction.  Any such arbitration shall be held in
Santa Clara  County,  California  under the rules then in effect of the Judicial
Arbitration  and Mediation  Services,  Inc. For purposes of this Section 8.4, in
any arbitration hereunder in which any claim or the amount thereof stated in the
Officer's  Certificate  is at issue,  the  Indemnitee  shall be deemed to be the
non-prevailing  party of the arbitration in the event that the arbitrators award
the Indemnitee  less than the sum of one-half (1/2) of the disputed  amount plus
any amounts not in dispute; otherwise, the Indemnifying Party shall be deemed to
be the non-prevailing  party. The  non-prevailing  party to an arbitration shall
pay its own expenses,  the fees of each arbitrator,  the administrative costs of
the arbitration,  and the expenses,  including  without  limitation,  reasonable
attorneys' fees and costs, incurred by the other party to the arbitration.

                  (e) In the event any Indemnitee becomes aware of a third-party
claim which such Indemnitee believes may result in an Indemnifiable  Claim, such
Indemnitee  shall promptly  notify the  Indemnifying  Party of such claim,  and,
provided  that  the  Indemnifying  Party  acknowledges  that  such  claim  is an
Indemnifiable   Claim,  the  Indemnifying  Party  shall  be  entitled,   at  the
Indemnifying  Party's expense,  to participate in any defense of such claim. The
Indemnitee shall have the right in its sole discretion to settle any such claim;
provided,  however,  that, except with the consent of the Indemnifying Party, no
settlement  of  any  such  claim  with  third-party  claimants  shall  alone  be
determinative  of the amount of any  Indemnifiable  Claim. In the event that the
Indemnifying  Party has consented to any such settlement and  acknowledged  that
the claim is a Indemnifiable  Claim, the Indemnifying  Party shall have no power
or authority to object under any provision of this Article VIII to the amount of
any Indemnifiable Claim by such Indemnitee with respect to such settlement.

         8.5 Survival of Environmental  Covenants. The obligations and rights of
Komag  and  Company  with  respect  to  (i)  Seller's   Retained   Environmental
Liabilities   and  (ii)  the   representations   made  in  Section  3.22  hereof
(collectively  the  "Environmental  Covenants") are in addition to,  independent
from,  and severable  from the rights and  obligations  of the Parties under all
other provisions of this Agreement.  It is expressly acknowledged by all Parties
hereto that neither the acts or omissions of any Party  hereto,  nor any failure
of any condition or breach of a representation contained in the Agreement or any
related agreements, shall impair the right of Komag to enforce the Environmental
Covenants  for  their  benefit,  it  being  understood  that  the  Environmental
Covenants  are being  given  consideration  of the  closing of the  transactions
contemplated by the Agreement and not in consideration of future  performance or
any  representation,  and are  intended to  allocate  risk of loss and to create
rights and obligations with respect to the matters covered by the  Environmental
Covenants  between the Parties  without regard to the conduct of any Person.  No
failure of any Person to exercise its rights under the  Environmental  Covenants
and no delay in exercising any right or remedy  hereunder,  at law or in equity,
shall  operate  as a waiver of the  agreements  contained  in the  Environmental
Covenants; nor shall the Parties be estopped from exercising any right or remedy
at any future time because of any such failure or delay; nor shall any single or
partial  exercise  of any such  right or  remedy  preclude  any  other or future
exercise thereof or the exercise of any other right or remedy. The Environmental
Covenants shall survive the sale, transfer,  assignment, or hypothecation of any
ownership  interest in a party benefited  hereby or obligated  hereunder and the
sale, transfer, assignment, or hypothecation of the Acquired Assets or any Media
Business Facility,  or any portion thereof or interest therein,  by Komag to any
Person.

                                   TERMINATION

         9.1  Termination of Agreement.  This Agreement may be terminated at any
time prior to the Closing as provided below:

                  (a) the Parties may terminate this Agreement by mutual written
consent at any time prior to the Closing;

                  (b) Komag  may  terminate  this  Agreement  by giving  written
notice  to the  Company  at any  time  prior to the  Closing  if Komag is not in
material  breach of its  obligations  under this  Agreement and there has been a
breach of any representation,  warranty, covenant or agreement contained in this
Agreement  on the  part  of the  Company  and as a  result  of such  breach  the
condition set forth in Section  7.2(a) or 7.2(b),  as the case may be, would not
then be  satisfied;  provided,  however,  that if such  breach is curable by the
Company  within  thirty  (30) days  through  the  exercise  of its  commercially
reasonable  efforts,  then for so long as the Company continues to exercise such
commercially  reasonable  efforts Komag may not terminate this  Agreement  under
this Section 9.1 unless such breach has not been cured  within  thirty (30) days
(but no cure period shall be required for a breach which by its nature cannot be
cured);

                  (c) the Company may terminate this Agreement by giving written
notice  to Komag  at any time  prior to the  Closing  if the  Company  is not in
material  breach of its  obligations  under this  Agreement and there has been a
breach of any representation,  warranty, covenant or agreement contained in this
Agreement on the part of Komag and as a result of such breach the  condition set
forth in  Section  7.3(a)  or  7.3(b),  as the case  may be,  would  not then be
satisfied;  provided,  however,  that if such breach is curable by Komag  within
thirty (30) days through the exercise of its  commercially  reasonable  efforts,
then for so long as Komag  continues to exercise  such  commercially  reasonable
efforts the Company may not  terminate  this  Agreement  under this  Section 9.1
unless  such  breach has not been  cured  within  thirty  (30) days (but no cure
period shall be required for a breach which by its nature cannot be cured); or

                  (d) either Party may terminate  this Agreement at any time, if
there shall be any action  taken,  or any  statute,  rule,  regulation  or order
enacted,  promulgated or issued or deemed  applicable to the  Acquisition by any
Governmental Entity, which would: (i) prohibit Komag's ownership or operation of
all or any material portion of the Media Business or the Acquired  Assets,  (ii)
compel  Komag to dispose of or hold  separate  all or a material  portion of the
Media Business or the Acquired Assets or other  businesses or assets of Komag as
a result of the Acquisition or (iii) materially  limit the benefits  accruing to
such Party under the Volume Purchase Agreement.

         9.2  Effect  of  Termination.  In the  event  of  termination  of  this
Agreement as provided in Section 9.1,  this  Agreement  shall  forthwith  become
void,  and there shall be no liability or obligation on the part of Komag or the
Company, or their respective officers, directors or shareholders;  provided that
each party shall remain liable for any breaches of this  Agreement  prior to its
termination;  and provided  further that,  the  provisions of Sections 6.2, 6.3,
6.8(e),  10.10 and 10.14 and Article VIII of this Agreement shall remain in full
force and effect and survive any termination of this Agreement.

         9.3  Escrow  Agreement;   Distribution  of  Property.   Notwithstanding
anything  contained in this Agreement to the contrary,  upon consummation of the
Acquisition, the Property (as defined in the Escrow Agreement) shall immediately
be  distributed  to  Komag;  provided,  however,  that,  if  this  Agreement  is
terminated prior to the  consummation of the Acquisition,  the Property shall be
distributed in accordance with Section 14(b) of the Escrow Agreement.

                            VOLUME PURCHASE AGREEMENT

         This Volume Purchase  Agreement,  dated as of April 8, 1999, is made by
and between Komag,  Incorporated,  a Delaware corporation  ("Komag") and Western
Digital Corporation, a Delaware corporation ("WDC").

         A. Komag and WDC are entering into an Asset Purchase  Agreement of even
date herewith  pursuant to which Komag is acquiring  certain  assets used in the
production of certain product components (the "Asset Purchase Agreement").

         B. The parties  acknowledge that this Volume Purchase Agreement is part
of a significant  strategic  relationship,  in which Komag is purchasing  assets
from WDC to  produce  media  and WDC is  agreeing  to  purchase  certain  of its
requirements  of  media  from  Komag,  and  Komag is  agreeing  to  supply  such
requirements  to WDC, to enable  Komag to spread  costs for media over a greater
volume,  and to enable Komag to incur the  significant  research and development
costs  associated  with the  historically  rapid  technology  advances and short
product  cycles for media,  and to enable WDC to obtain  favorable  pricing on a
consistent  supply of  high-quality,  state-of-the-art  media, all to the mutual
benefit of Komag and WDC.

         C. WDC desires to purchase,  and Komag desires to sell to WDC,  certain
products  manufactured  using  such  acquired  assets as well as other  products
manufactured by Komag,  all in accordance with the terms of this Volume Purchase
Agreement.

         NOW THEREFORE,  for and in consideration of the covenants,  conditions,
and undertakings hereinafter set forth, as well as a portion of the stock issued
pursuant to the Asset Purchase Agreement, the parties agree as follows:


                             ARTICLE 1: DEFINITIONS

cooperate with the other party to accomplish the objectives of this VPA.

         2.2 Agreement Components.  This VPA consists of this VPA (including its
Exhibits),  Purchase Orders and Pull Requests.  If there is a conflict among the
terms and  conditions  of the  various  documents  or an  ambiguity  created  by
differences  therebetween,  the  order  of  precedence  will  be  (i)  this  VPA
(excluding its  Exhibits),  (ii)  Exhibits,  and (iii) Purchase  Orders and Pull
Requests.

         2.3 Purchase Order. Purchase Orders will be used to convey the Purchase
Orders Price and number of Units,  and accordingly  Purchase Orders must contain
the following: part number, Price, Units ordered, customer name, ship to address
(destination),  bill to address, and Purchase Order number. Delivery Dates shall

invoices and the like used in the ordinary  course of business may contain other
terms and conditions.  The parties agree that this VPA will take precedence over
any  such  document  or other  communication,  representation  or  understanding
whether oral or written and that any term or  condition  relating to the subject
matter of this VPA that is inconsistent  with this VPA (whether in contradiction
to, in addition  to, or that would result in any  ambiguity  with respect to any
term or  condition  in this  VPA)  will be  deemed  deleted  and be of no force,
including,  but not limited to, any term or  condition  purporting  to supersede
this VPA in whole or in part or purporting to make any offer, acceptance,  term,
condition  or  other  action  conditional  upon  acceptance  of,  or  indicating
agreement  to, any  inconsistent  term or  condition.  The  foregoing may not be

         Exhibit C:        Qualification Sample Prices

         Exhibit D:        Supplier Warranty and Replacement Product Terms


                ARTICLE 3: PRODUCT QUALIFICATION AND DEVELOPMENT

         3.1 Qualification  Process.  Each of the parties shall use commercially
reasonable  efforts to qualify  Komag's  Products on all Programs.  Such efforts
will require  qualification  of Products in  combination  with other  Components
(such as multiple  combinations  of Media and recording  heads),  as well as the
subsequent qualification of WDC's disk drives incorporating such combinations at
each  WDC   customer.   Subject  to  Section   4.3,   WDC  agrees  that  Product
qualifications must include sufficient WDC Programs,  Component combinations and
customers to allow WDC to meet its Purchase Requirements for Products under this
VPA,  taking  into  account  that a Product  may fail to qualify in a Program or
Components combination, or for a customer, from time to time.

         3.2  Qualification  Locations.  Following  the  Effective  Date,  Komag
intends to manufacture  Products  under this Agreement  using in-line and static
sputtering  processes  at  factory  locations  in  Santa  Clara  and  San  Jose,
California,  and in  Penang,  Malaysia.  Both  parties  recognize  that WDC must
qualify  Products for its Programs  specifically by process and factory location
in accordance with industry practice.

         4.4  Quarterly   Milestones.   The  Purchase  Requirements  are  annual
requirements. However, without limiting either party's obligations under Section
4.1, WDC shall use commercially  reasonable efforts to purchase, and Komag shall
use commercially  reasonable  efforts to sell to WDC, in each Fiscal Quarter,  a
number of Units consistent with WDC's forecast referenced in Section 5.1.

         4.5 Additional  Demand.  WDC may, but will not be obligated to, request
that Komag provide Units in excess of the Purchase Requirements. Purchase Orders
for such additional  Units may be issued at any time by WDC, but will be subject
to acceptance by Komag in its sole discretion.  Pricing and other terms for such
excess Units shall be  separately  negotiated  and not subject to the Prices and
terms set forth in this VPA.


                     ARTICLE 5: PURCHASE OF PRODUCTS BY WDC

         5.1 Forecasts and Planning Schedules.  By the Effective Date, WDC shall
provide to Komag a current  written  forecast of demand for Products WDC expects
to purchase  during the first twelve months of the term of this VPA.  Thereafter
during the term of this VPA, on a monthly  basis,  WDC shall  provide an updated
forecast  for any  quantities  of such  Product  WDC  expects to purchase in the
following  twelve months.  The most recently  issued forecast will supersede all
previous  forecasts.  No less than five Days from receipt of each of the monthly
WDC  forecasts,  Komag shall  confirm  supply for a rolling  three month  period
(current month plus two). During the term of this VPA on a monthly basis,  Komag
shall provide to WDC a current  written  summary of the Product  finished  goods
inventory   ("FGI")   intended  for  WDC.  This  summary  shall  list  by  Komag
manufacturing  site and JIT Hub location the amounts and types of FGI being held
by Komag for each of WDC's Programs.

         5.2 Issuing  Purchase Orders and Pull Requests.  WDC shall, at least 30
Days before the  beginning  of each Fiscal  Quarter,  submit to Komag a Purchase
Order for such Fiscal  Quarter for all Units WDC has  forecasted  it may require
during such Fiscal Quarter. No less than two Business Days after receipt of each
Purchase Order, Komag shall issue an acknowledgement confirming the quantity and
other terms  thereof.  WDC shall  transmit a Pull  Request by facsimile or other
agreed upon means to communicate  to Komag,  at the applicable JIT Hub, the part
number,  quantity and Delivery  Date and time of each  Product  required.  WDC's
transmission  of a Pull Request is  authorization  for Komag to ship and invoice
WDC against the Purchase  Order for the part numbers and quantities set forth in
the Pull Request.  Komag shall deliver  Product from the JIT Hub upon receipt of
the Pull Request,  in accordance with Lead Times. WDC and Komag shall,  prior to
the  commencement of each Fiscal  Quarter,  establish  mutually  acceptable Lead
Times for Pull Requests, which Lead Times shall in no event exceed eight hours.

         5.3 Komag  Production and  Inventory.  During the term of this VPA, WDC
will be issuing forecasts and Purchase Orders and Komag will be producing FGI to
meet WDC's needs shown in the  Purchase  Orders.  WDC's  forecast  for a certain
Fiscal Quarter are not commitments by WDC to buy a specific amount of Product in
a specific  period of time.  Komag will use WDC's  forecast  for planning of its
production capacity to support WDC. Unless given written  authorization by a WDC
Materials  manager to make a temporary  exception,  Komag shall manage and limit
its  production  of FGI so that on any given date FGI does not exceed WDC's most
current forecasted  requirements of FGI for the subsequent four week period (the
"Target FGI").  Komag shall maintain  Products in inventory for WDC at locations
close to WDC factories ("JIT Hubs"). Provided WDC has issued a relevant Purchase
Order,  Komag  shall,  promptly  after  the  Effective  Date,  use  commercially
reasonable efforts to establish a level of Product inventory for each Program at
each JIT Hub equal to the JIT Hub  Inventory  Watermark  and to  replenish  each
reduction  requested by WDC from such inventory  within four weeks from the date
of such reduction.

         5.4 End of Life.  WDC  shall use  commercially  reasonable  efforts  to
notify Komag as soon as possible before the termination of each Program.

         5.5  Liability  on  Cancellation.  Subject to WDC's  obligations  under
Section  4, WDC shall  have the right to cancel  Purchase  Orders  for  Products
(except the final  Purchase  Order  issued  under  Section 9.1) , in whole or in
part,  placed in accordance  with the provisions of this VPA upon written notice
to Komag.  WDC's maximum liability to Komag for FGI upon such cancellation shall
be limited to [***].

         Notwithstanding  the foregoing,  during the ramp period of any Product,
not to exceed six weeks,  the  parties  shall first meet and agree on the number
equal to "IW" for the purpose of  calculating  liability  under this Section 5.5
for any cancellation of a Purchase Order which occurs during any portion of such
a ramp period. Komag shall (i) use all commercially reasonable efforts to find a
substitute  buyer and mitigate any potential loss; (ii)  participate in an audit
of lead time efficiency as reasonably requested by WDC; and (iii) negotiate with
WDC to adjust the above  formula for  reductions  in the lead time to  fabricate
Media that are achieved by Komag.


                ARTICLE 6: PRICE AND PAYMENT TERMS FOR PRODUCTS

         6.1 Product Pricing.  The initial Unit Prices WDC will pay for Products
purchased during the first [***] months of the term of this VPA are set forth in
Exhibit B. Commencing with the first [***] after such [***] period,  the parties
shall,  beginning  no later than [***] Days before the  beginning of such [***],
negotiate  Prices for the Products on a [***] basis (the "Prices").  The parties
shall conclude such  negotiations  no later than [***] Days before the beginning
of such [***].  Komag  shall,  no later than [***] Days before the  beginning of
each such [***],  notify WDC of the agreed-upon  Prices applicable to such [***]
by means of a pricing letter. [***]  Notwithstanding the foregoing,  the parties
agree that the review of such  prices and terms  shall not  require  the parties
[***]. [***].

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


         6.2  Pricing  Disputes.  In the event the  parties  cannot  agree  upon
pricing as described in Section 6.1,  either party may,  upon written  notice to
the other,  submit such dispute to the Chief Executive Officer of Komag; and the
Chief Executive Officer of WDC, or their respective designees, who shall meet to
attempt to resolve  the  dispute  by good faith  negotiations.  In the event the
parties are unable to come to  agreement  upon  Prices  within 5 Days after such
notice is given,  either  party may proceed  with  arbitration  as follows.  The
parties  will  submit  the  matter of  pricing  to  binding  arbitration  in San
Francisco,  California,  in accordance with the Commercial  Arbitration Rules of
the  American  Arbitration  Association  ("AAA").  Each party shall  appoint one
arbitrator,  and  the  two  arbitrators  thus  appointed  will  appoint  a third
arbitrator.  The parties shall instruct the  arbitrators to make a determination
of pricing using the standards set forth in Section 6.1, but in no event outside
of the range of the "bid"  and  "asked"  prices  established  by the  respective
positions of the parties in the last good faith  negotiations  prior to referral
to  arbitration.  The  parties  shall also  instruct  them to come to a decision
within 20 Days  after  submission  of the  dispute  to  arbitration.  During the
pendency  of such  arbitration,  the  Prices in effect  immediately  before  the
arbitration shall remain in effect. If a price change is awarded,  the party, if
any,  which owes a balance shall pay such  balance;  and in the event such party
fails to pay such balance within ten Days after the date of the award,  interest
will accrue  beginning ten Days after the date of the award, at the maximum rate
permitted by law in California.  Each party shall bear its own arbitration costs
and expenses;  provided, however, that the arbitrators may modify the allocation
of fees, costs and expenses in the award in those cases where fairness  dictates
other than each party bearing its own fees, costs and expenses.  The award shall
be final and binding on the parties, and judgment on the award may be entered in
and enforced by any court of competent jurisdiction.

         6.3 Taxes and Duties.  Unless otherwise  specifically  provided herein,
the  amount  of any  present  or  future  sales,  revenue,  excise  or other tax
applicable to the Products,  will be added to the Price and will be paid by WDC,
or in lieu  thereof WDC shall  provide  Komag with a tax  exemption  certificate
acceptable to the taxing authorities.  In the event Komag is required to pay any
such tax, fee, or charge, at the time of sale or thereafter, WDC shall reimburse
Komag therefor.  Notwithstanding the foregoing,  WDC will not be responsible for
any taxes on Komag's income.

         6.4 Tax  Minimization.  The parties  acknowledge that Komag's Malaysian
manufacturing  operations,  including the tax holiday status of such operations,
provide a path to the  industry's  lowest  cost  structure.  To ensure that both
parties  derive  benefit  from this  advantageous  manufacturing  location,  the
parties  shall adopt  business  practices  (e.g.  sales  terms,  title  passage,
importer of record,  and  warehousing  practices)  that maximize the benefits of
Komag's tax holiday  position  in Malaysia to the extent not  inconsistent  with
WDC's reasonable business objectives.

         6.5 Payment Terms.  For shipments  through Komag's  designated JIT Hub,
Komag shall invoice WDC upon delivery of Product to the receiving  dock of WDC's
manufacturing locations in Malaysia and Singapore.  For shipments direct to WDC,
Komag will invoice upon shipment.  Terms for payment of all invoices will be net
[***] Days from date of invoice.  In the event  payment is not received by Komag
within such period,  Komag shall notify WDC and WDC shall make prompt

payment  of the  amount  due.  WDC will be liable for  interest  on any  overdue
payment  under any such  invoice,  up to the maximum  legal rate in  California.
Notwithstanding the foregoing,  payment terms shall be payment in advance in the
event of the  bankruptcy or insolvency of WDC or in the event any  proceeding is
brought (a)  voluntarily by WDC under the bankruptcy or insolvency  laws; or (b)
involuntarily  against WDC under the  bankruptcy  or  insolvency  laws,  and not
dismissed within 90 Days.

         6.6 Late  Payments.  If (a) WDC's account with Komag is past due in any
amount,  by more than [***]  Days;  (b) WDC does not make  payment in advance as
required  under  Section 6.5; or (c) if WDC's  account with Komag is past due in
any amount in excess of the  greater  of (i)  $[***];  and (ii)  [***]% of WDC's
total accounts receivable balance under this Agreement; by more than [***] Days;
then Komag may  discontinue  shipping  Products upon [***] Days' advance written
notice to WDC and  opportunity  for WDC to cure  within such  [***]-Day  period.
Units that Komag does not ship in  accordance  with this  Section  6.6 shall not
count towards the Units  purchased by WDC to fulfill its Purchase  Requirements,
until such Units are shipped by Komag.  The parties agree that a senior  officer
designated  by each party will meet to resolve  any issues  relating  to overdue
amounts.


                  ARTICLE 7: SHIPMENT AND DELIVERY OF PRODUCTS

         7.1 Shipment of Product.  Except as otherwise specified with respect to
direct  shipments  under Section 6.5,  Delivery will be made DDU (i.e.,  the ICC
standard  shipping  term for delivery  duty  unpaid),  and liability for loss or
damage to Products  will pass to WDC upon  Komag's  delivery of the  Products to
WDC. As between the parties,  Komag will bear the cost for insurance relating to
delivery of the Products.  For deliveries within Malaysia or Singapore,  Western
Digital   Malaysia  SDN.  BHD.  or  Western   Digital   (Singapore  Pte.  Ltd.),
respectively,  will be the "importer of record" for GST  purposes.  The Products
shall be  delivered  to WDC from a Komag  JIT Hub to a WDC  factory.  Komag  may
deliver the Products in installments  subject to Section 5.2.  Unless  otherwise
agreed,  all Products will be packaged,  and packed in  accordance  with Komag's
normal  practices.  All Product  packages  shall be labeled in  accordance  with
applicable customs regulations. Komag may ship, determine freight forwarder, and
provide  delivery  support by the method it deems most  advantageous.  WDC shall
ensure   that  the   freight   forwarder   selected   by  Komag  may  use  WDC's
"Manufacturer's  Export Status" for shipments on behalf of WDC to Singapore,  so
long as the parties mutually agree.  Transportation  charges are included in the
Unit Price.  Komag shall  deliver,  upon  request from WDC,  appropriate  import
certificates  for duties paid on Media  purchased from Komag,  imported by Komag
into the United States and delivered to WDC in the United States.

         7.2 On Time Delivery.  Komag shall use commercially  reasonable efforts
to maintain 100% on-time delivery of each Pull Request from a JIT Hub.

         7.3 Late Delivery. Komag shall notify WDC immediately if for any reason
Komag fails to comply or  anticipates  that it may fail to comply with the terms
of a Pull  Request  (including,  but not limited to,  failure to meet a Delivery

disruption caused to WDC by such late delivery.

         7.4 Export  Regulations.  WDC and Komag  shall  comply  with all export
control laws and regulations applicable to the export or reexport of Products or
any related  technology.  The party undertaking such export or reexport shall be
responsible for obtaining any required  documents,  authorizations and approvals
prior to any such export or reexport.


          ARTICLE 8: WARRANTIES AND INTELLECTUAL PROPERTY INFRINGEMENT

         8.1 WDC General  Warranties.  WDC has the corporate power and authority
to own its properties and to carry on its business as now being conducted and as
contemplated  to be conducted.  WDC is duly qualified to do business and in good
standing as a foreign  corporation  under the laws of each jurisdiction in which
the failure to be so qualified would have a material adverse effect on WDC.

         8.2 Product Limited Warranty.  Komag's warranty for Products under this
Agreement, and the remedies for breach of such warranty, will be as set forth in
Exhibit D.

         8.3  Disclaimer.  THE WARRANTIES AND  OBLIGATIONS OF THIS SECTION 8 AND
EXHIBIT  D WILL BE  EXCLUSIVE  AND IN LIEU  OF ANY  AND  ALL  OTHER  WARRANTIES,
EXPRESS,  IMPLIED OR STATUTORY,  INCLUDING BUT NOT LIMITED TO THE  WARRANTIES OF
MERCHANTABILITY,  FITNESS FOR A PARTICULAR  PURPOSE AND  NONINFRINGMENT,  ALL OF
WHICH ARE HEREBY EXPRESSLY DISCLAIMED.

         8.4 Infringement Indemnity

                  8.4.1  Indemnification.  Komag shall defend any claim, suit or
proceeding brought against WDC to the extent such suit or proceeding is based on
a claim that any Product furnished hereunder,  alone and not in combination with
any  other  product,  constitutes  an  infringement  of any U.S.  patent or U.S.
copyright,  provided  WDC gives Komag prompt  notice of any such claim,  suit or
proceeding,  in writing and authorizes Komag to settle or defend any such claim,
suit or  proceeding  and  assists  Komag in so doing (at Komag's  expense)  upon
request  by  Komag.  Komag  shall pay WDC's  reasonable  attorneys  fees and all
damages  and costs  awarded  against  WDC  arising  out of such  claim,  suit or
proceeding.

                  8.4.2 Limited  Remedies.  If the use of a Product is enjoined,
Komag shall, in its sole  discretion and at its own expense,  either (a) procure
for WDC the right to  continue  using  such  Product;  (b)  replace  same with a
noninfringing  product; (c) modify the Product so that it becomes noninfringing;
or (d) if Komag is unable to  reasonably  do any of the above,  refund the Price
for such Product.

                  8.4.3 Exclusions. Komag shall not be liable for, and WDC shall
indemnify,  defend and hold Komag harmless from, any expenses, damages, costs or
losses resulting from any suit or proceeding based upon a claim arising from (a)
compliance  with  WDC's  designs,   specifications,   or  instructions;   (b)  a
modification  of the  Product by a party  other than  Komag;  (c) the use of any
Product  or part  thereof  furnished  hereunder  in  combination  with any other
product;; or (d) intellectual  property  infringements to the extent arising out
of the use of the  Acquired  Assets  (as such  term is  defined  under the Asset
Purchase  Agreement),  or any technology or  intellectual  property  licensed or
otherwise  provided to Komag in  connection  with the Acquired  Assets under the
Asset Purchase Agreement,  if such infringements would not have arisen using the
assets,  technology  and  intellectual  property  used  by  Komag  prior  to the
Effective Date. WDC shall pay Komag's reasonable  attorneys fees and all damages
and costs awarded against Komag arising out of such claim, suit or proceeding.

                  8.4.4  License.  Sale of any  Product  or any part  thereof by
Komag  does  not  confer  upon  WDC any  license  under  any  patent  rights  or
copyrights.

                  8.4.5 SOLE  LIABILITY.  THIS  PROVISION  8.4 IS IN LIEU OF ALL
OTHER EXPRESS,  IMPLIED OR STATUTORY WARRANTIES AGAINST INFRINGEMENT AND WILL BE
THE SOLE AND EXCLUSIVE  REMEDY FOR  INTELLECTUAL  PROPERTY  INFRINGEMENT  OF ANY
KIND. IN NO EVENT SHALL KOMAG'S TOTAL LIABILITY FOR SUCH INFRINGEMENT EXCEED THE
AGGREGATE SUM PAID BY WDC FOR THE ALLEGEDLY INFRINGING PRODUCTS.


                         ARTICLE 9: TERM AND TERMINATION

         9.1 Term.  This VPA will continue in force for an initial term of three
years after the Effective  Date,  and will  terminate at the end of such initial
term unless  otherwise  agreed by the Parties in writing.  In the event WDC does
not wish to renew the term of this Agreement  after such initial term, WDC shall
notify  Komag no later than 30 Days  before the  beginning  of the final  Fiscal
Quarter of such initial term,  and issue to Komag a binding final Purchase Order
for such Fiscal Quarter.

         9.2 Termination  for Cause.  Either party may terminate this VPA in the
event of a Material Default of this VPA by the other party,  upon notice to such
other party, which notice must describe the reason for such termination and must
specify the termination  date, which  termination date must be no earlier than 5
Days after the date of such notice.  The parties  acknowledge that neither party
will  have the  right to  terminate  this  Agreement  due to any  breach of this
Agreement other than a Material  Default;  and in the case of such other breach,
subject to Sections 10.2 and 11.6, the  non-breaching  party's only remedy under
this Agreement will be an action for damages.

         9.3 Termination  for  Insolvency.  This VPA may be terminated by either
party by notice to the other party upon (i) the  commencement by the other party
of a voluntary or involuntary

proceeding  under any federal,  state,  provincial or foreign  bankruptcy law or
similar law which is not dismissed  within 90 Days; (ii) the appointment for the
other party of a receiver,  trustee or similar official or a general  assignment
for the benefit of such party's  creditors;  (iii) the winding up or liquidation
of the other  party;  or (iv) a party  becomes  unable  to pay its debts  either
because it is subject to a Suspension of Payments  order,  bankruptcy,  or other
insolvency proceeding. In the case of (i) to (iv) above, termination may also be
effected by serving notice on the liquidator, administrator, or receiver, as the
case may be.

         9.4 Rights Upon Termination. Upon termination, Komag shall complete and
WDC shall pay for all  Products in  accordance  with Section 6.5 and Komag shall
continue to perform its obligations  with respect to Replacement  Products under
Exhibit D. Komag and WDC shall  cooperate to perform an orderly  Disentanglement
following termination.

         9.5 Survival.  The following provisions will survive the termination or
expiration  of this VPA:  Articles 1, 2, 8, 9.4,  10, 11, and 12, as well as any
obligations arising before the effective date of termination or expiration.


                       ARTICLE 10: LIMITATION OF LIABILITY

         10.1 Limitation of Liability.  EXCEPT FOR ARTICLE 11 (CONFIDENTIALITY),
NEITHER  PARTY  SHALL  BE  LIABLE  TO THE  OTHER  FOR  CONSEQUENTIAL,  INDIRECT,
INCIDENTAL,  SPECIAL OR PUNITIVE  DAMAGES EVEN IF ADVISED OF THE  POSSIBILITY OF
SUCH DAMAGES.

         10.2 Performance.  Notwithstanding the foregoing,  in light of the fact
each of the parties  entered into the Asset  Purchase  Agreement and this VPA in
reliance  on the  full  and  faithful  performance  by the  other  party  of its
obligations  (including  but not  limited  to  purchase  and  sale  obligations)
hereunder,  the parties agree that damages  would be an inadequate  compensation
for the breach by the parties of such obligations and accordingly, upon any such
breach, in addition to monetary damages,  a party shall be entitled to obtain an
order  for  specific  performance  of  such  obligations  at  any  court  having
jurisdiction over the other party.

         10.3 Year 2000 Liability. Except for WDC's right to purchase from other
suppliers  as  provided  under  Section  4.3,  in no event  shall Komag have any
liability for any failure to provide  Products  hereunder prior to July 1, 2000,
if such failure is  attributable  to the failure of any Acquired Assets (as such
term is defined in the Asset Purchase Agreement) to be year 2000 compliant.


                          ARTICLE 11: CONFIDENTIALITY

         11.1 "Confidential  Information" means any information disclosed by one
party (the "Disclosing  Party") to the other (the "Receiving Party") in relation
to this VPA, which, if in written,  graphic,  machine-readable or other tangible
form is marked as "Confidential" or "Proprietary," or which, if disclosed orally
or by  demonstration,  is  identified  at the  time  of  initial

disclosure as confidential  and reduced to a writing marked  "Confidential"  and
delivered to the Receiving Party within 30 Days of such disclosure.

         11.2 Exclusions. Notwithstanding Section 11.1, Confidential Information
will exclude information that the Receiving Party can demonstrate:

                  11.2.1 was  independently  developed  by the  Receiving  Party
without any use of the  Disclosing  Party's  Confidential  Information or by the
Receiving Party's employees or other agents (or independent contractors hired by
the  Receiving  Party)  who have  not been  exposed  to the  Disclosing  Party's
Confidential Information;

                  11.2.2   becomes  known  to  the  Receiving   Party,   without
restriction,  from a source other than the  Disclosing  Party without  breach of
this VPA and that had a right to disclose it;

                  11.2.3 was in the public  domain at the time it was  disclosed
or becomes in the public  domain  through no act or  omission  of the  Receiving
Party; or

                  11.2.4 was rightfully  known to the Receiving  Party,  without
restriction, at the time of disclosure.

         11.3 Compelled  Disclosure.  If a Receiving Party believes that it will
be compelled by a court or other authority to disclose Confidential  Information
of the  Disclosing  Party,  it shall give the  Disclosing  Party prompt  written
notice so that the  Disclosing  Party may take steps to oppose such  disclosure,
and the  Receiving  Party  shall  assist  in  opposing  such  disclosure  at the
Disclosing Party's expense.

         11.4 Confidentiality Obligation.  During the term of this VPA and for a
period  of  five  years   thereafter,   the  Receiving  Party  shall  keep  such
Confidential  Information  in strict  confidence  and shall  not  disclose  such
Confidential Information to any third party without prior written consent of the
Disclosing Party.

         11.5 Confidentiality of Agreement. Each party agrees that the terms and
conditions,  but not the  existence,  of this VPA will be treated as the other's
Confidential  Information  and that no reference to the terms and  conditions of
this VPA or to activities  pertaining  thereto can be made in any form of public
or commercial  advertising without the prior written consent of the other party;
provided, however, that each party may disclose the terms and conditions of this
VPA: (i) subject to the  provisions  of Section 11.3 as required by any court or
other  governmental  body;  (ii) as  otherwise  required by law;  (iii) to legal
counsel of the parties;  (iv) in connection  with the  requirements  of a public
offering,  secondary  offering,  debt  offering,  or  securities  filing  of the
parties,  or otherwise as obligated by law; (v) in confidence,  to  accountants,
banks,  and financing  sources and their  advisors;  or (vi) in  confidence,  in
connection with the enforcement of this VPA or rights under this VPA.

         11.6  Remedies.  Unauthorized  use  by a  party  of the  other  party's
Confidential Information will diminish the value of such information. Therefore,
if a party breaches any of its obligations  with respect to  confidentiality  or
use of Confidential  Information hereunder,  the other party will be entitled to
seek  equitable  relief to protect its interest  therein,  including  injunctive
relief, as well as money damages.

         11.7 Non-disclosure  Agreements.  Each party shall obtain the execution
of proprietary  nondisclosure agreements with its Affiliates,  including but not
limited to the party's  and/or  Affiliates'  respective  agents and  consultants
having access to Confidential  Information of the other party,  shall diligently
enforce such agreements with respect to the Confidential Information,  and shall
exercise due care to control the actions of such Affiliates,  employees,  agents
and consultants in this respect so long as they have a working relationship with
the party obligated hereunder to obtain such nondisclosure agreements.


                              ARTICLE 12: GENERAL

         12.1 Governing Law and Jurisdiction.  This VPA will be interpreted, and
the rights and liabilities of the parties hereto determined,  in accordance with
the laws of the State of California applicable to agreements executed, delivered
and performed  within such State,  without regard to the principles of conflicts
of laws thereof.  Each of the parties hereby consents to the jurisdiction of any
state or federal court located  within the county of Santa Clara in the State of
California  (except for  resolution of pricing  disputes as described in Section
6.2), and each of the parties  hereby:  (i) waives any objection to venue of any
action  instituted  under this VPA,  and (ii)  consents to the  granting of such
legal or equitable relief as is deemed appropriate by any aforementioned court.

         12.2 Force Majeure.  A defaulting party shall provide the nondefaulting
party immediate notice of any anticipated  delay or failure of compliance due to
a Force Majeure Event; provided, however, that any such act will not relieve the
defaulting party's obligations hereunder.

         12.3 Trademarks.  Nothing in this VPA gives either party a right to use
the other party's name, trademark(s),  or trade name(s), directly or indirectly,
without the other party's prior  written  consent,  except as may be required by
applicable  law or court order.  In such a case,  the party required to disclose
such  information  shall provide prompt notice of such requirement in order that
the other party may seek appropriate protective orders.

         12.4 Assignment. Except as set forth in this Section 12.4, neither this
Agreement,  nor any of the rights or  obligations  hereunder,  may be  assigned,
transferred,  subcontracted  or  delegated by a party hereto to any third party,
including  without  limitation,  by  operation of law or pursuant to a Change of
Control (as defined below).  Notwithstanding the foregoing, (a) Komag may assign

the prior  consent of WDC, to Komag USA  (Malaysia)  SDN; and (c) WDC may assign
this  Agreement,  and the rights and  obligations  hereunder,  without the prior
consent of Komag,  to a third party in connection  with a Change of Control;  so
long as WDC  assigns  all  obligations  under this  Agreement  to any party that
succeeds to all or substantially  all of WDC's disk drive  production  business.
For purposes of this Section 12.4,  "Change of Control" shall mean (i) any sale,
lease, exchange or other transfer (in one transaction or series of transactions)
of  all,  or  substantially   all,  of  the  assets  of  such  party,  (ii)  any
consolidation  or merger or other  combination of a party in which such party is
not the continuing or surviving  corporation or pursuant to which shares of such
party's common stock would be converted into cash,  securities or other property
(other than a merger of such party in which the holders of such  party's  common
stock  immediately  prior  to  the  merger  hold  at  least  a  majority  of the
outstanding  securities of the combined  entity),  or (iii) any  transaction (or
series of related  transactions)  pursuant  to which any  person (as  defined in
Section 13 of the  Securities  Exchange Act of 1934,  as amended (the  "Exchange
Act"), becomes the beneficial owner (as defined in Rule 13d-3 under the Exchange
Act),  directly or  indirectly,  of [***]% or more of such  party's  outstanding
common stock.  For purposes of this Section 12.4,  "Prohibited  Assignee"  shall
mean any third party who (x) [***] Any  purported  assignment of this VPA or the
rights or  obligations  of a party under this VPA in  violation  of this Section
12.4 shall be null, void and of no further force or effect and shall  constitute
a Material Default.

         12.5  Severability.  If any of the provisions of this VPA are held by a
court or other  tribunal of  competent  jurisdiction  to be  unenforceable,  the
remaining portions of this VPA will remain in full force and effect.

         12.6 Failure to Enforce.  The failure of either party to enforce at any
time or for any period of time the  provisions of this VPA will not be construed
to be a waiver of such  provisions or of the right of such party to enforce each
and every provision of this VPA in the future.

         12.7 Agency. This VPA does not create a principal to agent, employer to
employee,  partnership,  joint venture, or any other relationship except that of

the time the  Purchase  Order for such Unit was issued;  or (b) due to any other
cause, including without limitation a failure of or damage by WDC disk drives or

time the Purchase Order for such Unit is issued; and (b) be free from defects in
materials,  workmanship  and title under normal use and operation  (the "Limited

and  agree  on  a  one-time,  firm,   non-cancelable  purchase  order  for  such
Replacement Products;  (y) notwithstanding the provisions of Section 4.2 of this
Exhibit  D,  such  purchase  order  may be for less  than the  minimum  of Units
required  in Section 4.2 of this  Exhibit D, but the maximum  prices and maximum
price  increases of  Attachment  2 will  nevertheless  apply;  and (z) WDC shall
purchase all the Units ordered  thereunder within an agreed-upon period of time.
Thereafter,  Komag shall have no obligation to supply such Replacement Products.
The parties  acknowledge that for the Products listed in Attachment 2, there may
be occasions which, due to material changes in Komag's  production process (such
as the shift from Tucson / Phase 0 to Chandler / ILE; or aluminum  substrate  to
glass substrate) may require a change in the Replacement  Product Period, and if
so, the parties shall negotiate in good faith a Replacement  Product Period that
reflects such material change.

         3.4  Tracking.  The  parties  acknowledge  that  pursuant  to the Asset
Purchase  Agreement,  at Closing (as such term is defined in the Asset  Purchase
Agreement),  Komag  will  take  over  from WDC  production  of  certain  Product
inventory  and WIP. On or before  Closing,  WDC shall  develop a method to track
Media made by those  processes used by WDC at its "Santa Clara Media  Operation"
prior to the Closing  ("WDC  Processes"),  sufficient to  differentiate  between
Media made by the WDC  Processes  prior to Closing  (such  units,  "Santa  Clara
Pre-Closing  Units") and Product made by the WDC Processes  after Closing.  Such
method will include  [***] Until WDC  establishes  such method of tracking,  all
Units that Komag and WDC reasonably  determine are made using WDC Processes will
be deemed Santa Clara Pre-Closing Units.

         3.5 Supply of Replacement  Product for Santa Clara  Pre-Closing  Units.
For Santa Clara  Pre-Closing  Units of Products  included in Attachment 2, Komag
will supply Replacement Product as indicated therein.  The terms of this Exhibit
D with respect to  forecasting,  placement  of purchase  orders and pricing will
apply to such Replacement  Product.  Notwithstanding  the foregoing,  nothing in
this VPA shall require Komag to supply the following Products to WDC: [***].

         3.6   Calculating   the  Percentage  of  WDC  Liability.   The  parties
acknowledge  that  Units may not  conform to the  Specifications  due to various
causes, including without limitation (a) defects covered by the Limited Warranty
and occurring  within the Warranty  Term; (b) damage to such Units caused by WDC
disk drives or by Components thereof other than the Products; and (c) defects or
damage not occurring  within the Warranty Term. For Units that do not conform to
the  Specifications,  for whatever reason,  during the Replacement Product Term,
WDC shall  provide  reasonably  sufficient  data on Units that are removed  from
failed  drives to assess  (x) cause of  failure  and (y)  whether  the Units are
within the Warranty Term. By mutual  engineering  analysis of such data, WDC and
Komag  shall  agree  on the  percentage  of  WDC's  liability  ("%BL")  for such
failures.  Such  determination will be based on a percentage equal to the number
of Units of a Product  that fail,  due to all causes  other than  failure of the
Units to conform to the Limited  Warranty  during the Warranty Term,  divided by
the total Units of a Product that fail.  %BL will be determined for each Program
through  the use of the Media  Warranty  Verification  and  Disposition  Process
specified in Attachment 1. Any Unit that is

modified,  misused,  or  damaged  after  delivery  of such  Unit to WDC  will be
included in the numerator of fraction that determines the %BL.

         3.7 Pricing for Replacement  Product.  Prices for Replacement  Products
("Base Line Price" or "BP"),  whether  such  Products are subject to the Limited
Warranty or not, will be [***].

         3.8 Credit Value.  The credit value ("CV") will be calculated  for each
Product and Program as shown below. [***]

         3.9 Issuance of Credit Voucher.  No later than seven days after the end
of each month, Komag shall issue to WDC a credit voucher in the amount of the CV
for Units returned during such month.


            ARTICLE IV: FORECASTING, PURCHASE ORDERS AND FULFILLMENT

         4.1  Replacement  Product  Forecast.   Each  month  commencing  on  the
Effective  Date,  for each  Product,  WDC shall provide Komag with a forecast of
WDC's requirements for each Replacement  Product during the Replacement  Product
Period,  which  forecast  must be based  on an  estimated  failure  rate for the
relevant  Product.  WDC's  Replacement  Product  forecast  will  include  weekly
requirements for the first 13 weeks,  monthly  requirements for the 14th to 26th
weeks,  and Fiscal  Quarterly  requirements  for the balance of the  Replacement
Product Period. This Replacement Product forecast does not constitute a purchase
order.  Within five  Business  Days of  receiving  WDC's  forecast,  Komag shall
provide  feedback to WDC to support or challenge  the validity of the  forecast,
including a tentative delivery schedule.

         4.2  Purchase  Orders.  WDC  shall,  no later  than 60 Days  before the
beginning  of each  Fiscal  Quarter,  submit  to  Komag  a firm,  non-cancelable
purchase order for Replacement Products for such Fiscal Quarter.  Komag will not
be obligated to supply Units of Replacement Products ordered for each Program by
WDC for any  Fiscal  Quarter,  in excess  of 25% over the  Units of  Replacement
Products  forecasted  by WDC for such Program for such  Replacement  Product for
such Fiscal  Quarter,  but Komag shall use  commercially  reasonable  efforts to
supply such Replacement Products. Except as otherwise expressly provided herein,
each  purchase  order for a particular  Product  shall be for at least (a) [***]
Units for Products  made using  in-line  sputtering;  and (b) [***] for Products
made using  static  sputtering.  Except as  otherwise  provided  in Section  3.3
following Komag's notice as required  therein,  in the event that WDC desires to
place an order  for a  last-time  buy of fewer  than such  number of Units,  the
parties shall first agree to an appropriate Price for such purchase order, which
Price shall not be limited by the maximum percentage price increases and maximum
prices set forth in Attachment 2.

         4.3 Liability Limitation.  WDC's liability for cancellation of purchase
orders for  Replacement  Products  shall not exceed  the  quantities  and Prices
specified in the applicable purchase order.

         5.1 Komag Failure  Analysis  Obligations.  Komag shall use commercially
reasonable efforts to ensure that Komag is capable of executing failure analysis
for Products  corresponding  to the  relevant  Replacement  Products  during the
Replacement Product Period.

         5.2 [***]

         5.3 Increased  Forecasts.  If WDC's  Replacement  Product  requirements
forecasted under Section 4.1 of this Exhibit D for a Fiscal Quarter increases by
more than [***]% from the previous Fiscal Quarter's forecast, then [***]

         5.4 [***]  Exception.  Section 5.2 of this  Exhibit D will apply to the
[***] Program for only so long as WDC places  purchase  orders for and purchases
[***] Units or more of Replacement Product for the [***] in each Fiscal Quarter.
In the event that WDC does not do so,  Komag will notify WDC that WDC may make a
last-time  buy and will not be obligated to reimburse  WDC under  Section 5.2 of
this Exhibit D for forecasts  based on sales of disk drives in the [***] for any
cost in or after the first  Fiscal  Quarter  in which WDC fails to do so. In the
event that WDC desires to place an order for a last-time buy of fewer than [***]
of such Units,  the parties shall first agree to an  appropriate  Price for such
purchase order, which Price shall not be limited by the maximum percentage price
increases and maximum prices set forth in Attachment 2.
