                                 PROXY STATEMENT

                     FOR THE ANNUAL MEETING OF STOCKHOLDERS
                             TO BE HELD MAY 14, 1997


                                     GENERAL

         The enclosed  proxy is solicited on behalf of the Board of Directors of
Komag,  Incorporated,  a Delaware  corporation (the  "Company"),  for use at the
Annual  Meeting to be held on May 14,  1997.  The Annual  Meeting  will begin at
10:00 a.m. at Komag,  Incorporated,  Building 9, 1705  Automation  Parkway,  San
Jose,  CA 95131.  Stockholders  of record on March 17,  1997 will be entitled to
notice of and to vote at the Annual Meeting.

         This Proxy  Statement and  accompanying  proxy (the "Proxy") were first
mailed to stockholders on or about April 7, 1997.

Voting

         On March 17, 1997, the record date for  determination  of  stockholders
entitled to vote at the Annual Meeting,  there were 51,888,768  shares of Common
Stock  outstanding.  Each stockholder is entitled to one (1) vote for each share
of  Common  Stock  held by such  stockholder.  Directors  will be  elected  by a
plurality vote. Other matters submitted for stockholder  approval at this Annual
Meeting  will be decided  by the  affirmative  vote of a majority  of the shares
present or  represented  and entitled to vote on each such  matter.  Abstentions
with respect to any matter  other than the election of directors  are treated as
shares present or represented  and entitled to vote on that matter and thus have
the same effect as negative  votes. If shares are not voted by the broker who is
the  record  holder  of  the  shares,  or if  shares  are  not  voted  in  other
circumstances  in which proxy  authority is defective or has been  withheld with
respect to any matter,  these  non-voted  shares are not deemed to be present or
represented  for purposes of determining  whether  stockholder  approval of that
matter has been obtained.  Each stockholder voting for the election of directors
may cumulate such stockholder's  vote. Under cumulative voting, a stockholder is
allowed  one (1) vote per share  multiplied  by the  number of  directors  to be
elected  (nine (9) at this meeting) and may cast such  cumulative  total for one
(1)  nominee  or may  distribute  such  number  among as many  nominees  as such
stockholder chooses.

Revocability of Proxies

         Any person giving a proxy has the power to revoke it at any time before
its exercise. A proxy may be revoked by filing with the Secretary of the Company
at the Company's principal executive office, 1704 Automation Parkway,  San Jose,
California,  95131,  a notice of revocation or another signed proxy with a later
date.  You may also revoke your proxy by attending the Annual Meeting and voting
in person.

Solicitation

         The Company will bear the entire cost of  solicitation,  including  the
preparation,  assembly,  printing  and mailing of this Proxy  Statement  and any
additional   soliciting   materials   furnished  to   stockholders.   Copies  of
solicitation materials will be furnished to brokerage houses,  fiduciaries,  and
custodians  holding shares in their names that are beneficially  owned by others
so that they may forward these solicitation materials to such beneficial owners.
In  addition,  the  Company  may  reimburse  such  persons  for  their  costs of
forwarding the solicitation  materials to such beneficial  owners.  The original
solicitation  of  proxies  by  mail  may  be  supplemented  by  solicitation  by
telephone,  telegram or other means by directors,  officers, employees or agents
of the Company. No additional compensation will be paid to these individuals for
any such  services.  Except as described  above,  the Company does not presently
intend to solicit proxies other than by mail.

                                  ITEM NO. 1 --
                              ELECTION OF DIRECTORS

         The Bylaws of the Company  provide that the Board of Directors shall be
comprised of between eight (8) and twelve (12) directors,  with the exact number
to be fixed by the Board. The currently authorized number is nine (9) directors.
At the Annual  Meeting,  nine (9)  directors  will be elected to serve until the
Company's  next  Annual  Meeting  and until  their  successors  are  elected and
qualified.  The Board of Directors has selected  nine (9) nominees,  all of whom
are current directors of the Company.

         Each person nominated for election has agreed to serve if elected,  and
management  has no reason to believe  that any nominee  will be  unavailable  to
serve.  Unless  otherwise  instructed,  the proxy  holders will vote the proxies
received by them FOR the nominees named below. The nine (9) candidates receiving
the highest  number of affirmative  votes of the shares  entitled to vote at the
Annual Meeting will be elected directors of the Company.

Recommendation of the Board of Directors

         The Board of Directors  recommends that the  stockholders  vote FOR the
election of each of the following  nominees to serve as directors of the Company
for the  ensuing  year  until  the  next  Annual  Meeting  at which  time  their

serving as Chairman.  This  Committee  held one (1) meeting in fiscal year 1996.
The  Nominating  Committee has not instituted  proceedings to consider  nominees
recommended by security holders, but may do so in the future.

         The Special Stock Option Plan Administration  Committee (the "Secondary
Committee")  has separate but  concurrent  jurisdiction  with the Primary  Stock
Option Plan  Committee to administer the  discretionary  option grant program of
the Option Plan with respect to non-officer employees. The option grants made by
the Secondary  Committee will comply with certain guidelines  established by the
Primary Stock Option Plan Committee.  The Secondary Committee currently consists
of Dr. Chen and Mr. Johnson and performs its duties on an ongoing basis.

Director Remuneration

         Non-employee  Board  members  receive  $4,500 per fiscal  quarter and a
$1,000  meeting  fee for each  Board of  Directors  meeting  or Board  Committee
meeting attended, including telephonic meetings.  Non-employee Board members are
also eligible to receive periodic option grants under the Automatic Option Grant
Program  in effect for them under the Option  Plan.  Each  individual  who first
becomes  a  non-employee   Board  member,   whether  through   election  by  the
stockholders  or  appointment  by the Board,  will receive,  at the time of such
initial  election or  appointment,  a stock  option  grant for 30,000  shares of
Common Stock. In addition, on the date of each Annual Stockholders Meeting, each
individual  who is  re-elected  as a  non-employee  Board member will receive an
option grant for 7,500 shares of Common,  provided such individual has served on
the Board for at least six months. Each option grant will have an exercise price
equal to the fair market  value of the option  shares on the grant date and will
have a maximum  term of ten  years,  subject  to  earlier  termination  upon the
optionee's cessation of Board service.

         Each of the  non-employee  Board Members  re-elected at the 1996 Annual
Meeting (Messrs.  Barrett, Eyre, Federman,  Neil, Palevsky, Sun and Takebayashi)
received at the time an option grant for 7,500 shares with an exercise  price of
$34.1093  per share.  Each  option will  become  exercisable  for all the option
shares upon the optionee's completion of one year of Board service measured from
the grant date. However, the option will become immediately  exercisable for all
of the option shares upon an acquisition of the Company by merger, consolidation
or asset sale or upon  certain  other  changes in  control or  ownership  of the
Company.  Upon the successful completion of a hostile tender offer for more than
50% of the  Company's  outstanding  Common  Stock,  each of these  options  will
automatically  be  canceled,  and each  optionee  will in return  receive a cash
distribution  from the Company in an amount per  canceled  option share equal to
the excess of (i) the highest  reported  price per share of Common Stock paid in
the tender offer over (ii) the option exercise price payable per share.

                   ITEM NO. 2 -- APPROVAL OF AMENDMENTS TO THE
                         RESTATED 1987 STOCK OPTION PLAN

Introduction

         The  stockholders  are being asked to approve a series of amendments to
the  Company's  Restated  1987 Stock Option Plan (the  "Option  Plan") that will
effect the  following  changes:  (i)  increase  the maximum  number of shares of
Common  Stock  authorized  for  issuance  over the term of the Option  Plan from
15,640,000  to 18,140,000  shares,  (ii) render the  non-employee  Board members
eligible to receive option grants under the  Discretionary  Option Grant Program
in effect under the Option Plan,  (iii) allow  unvested  shares issued under the
Option Plan and  subsequently  repurchased by the Company at the option exercise
price paid per share to be reissued  under the Option Plan,  (iv) remove certain
restrictions on the  eligibility of non-employee  Board members to serve as Plan
Administrator and (v) effect a series of additional changes to the provisions of
the Option Plan (including the stockholder  approval  requirements)  in order to
take  advantage of the recent  amendments  to Rule 16b-3 of the  Securities  and
Exchange  Commission  which exempts  certain  officer and director  transactions
under the Option Plan from the short-swing  liability  provisions of the Federal
securities laws.

         The Board of Directors adopted these amendments in March 1997,  subject
to stockholder  approval at the Annual Meeting.  The Board believes the increase
in the  number  of shares  available  for  issuance  under  the  Option  Plan is
necessary in order to assure that the Company will have a sufficient  reserve of
Common Stock to continue to utilize option grants for purposes of attracting and
retaining the services of key individuals  essential to the Company's  long-term
success.  The Board believes the other amendments are needed in order to provide
the Company with more  opportunities to make equity incentives  available to the
non-employee  Board members as an inducement for their continued  service and to
facilitate  plan  administration  in light  of the new  changes  to Rule  16b-3.
However,  no option  grant made under the Option Plan as amended will have value
unless the market price of the Common Stock appreciates over the market price in
effect at the time of grant.

         The  following  is a summary of the  principal  features of the amended
Option Plan,  together with the tax and accounting  implications of transactions
effected  under the Option Plan. The summary,  however,  is not intended to be a
complete  description  of all the terms of the Option Plan. A copy of the Option
Plan will be furnished by the Company to any stockholder upon written request to
the Secretary of the Company at the corporate offices in San Jose, California.

Structure

         The  Option  Plan is  divided  into two (2)  separate  components:  the
Discretionary Option Grant Program and the Automatic Option Grant Program. Under
the Discretionary Option Grant Program,  options may be issued from time to time
to  key  employees  (including   officers),   non-employee  Board  members,  and
consultants  of  the  Company  (or  its  parent  or  subsidiary  companies)  who
contribute to the  management,  growth and financial  success of the Company (or
its parent or subsidiary companies). Under the Automatic Option Grant Program, a
series of automatic option grants will be made to the non-employee Board members
over their continued period of service on the Board.

         As of March 17, 1997,  approximately 368 employees  (including  fifteen
(15) executive officers), and seven (7) non-employee Board members were eligible
to  participate  (assuming  approval  of this Item No.  2) in the  Discretionary
Option  Grant  Program.  The  seven (7)  non-employee  Board  members  were also
eligible to participate in the Automatic Option Grant Program.

                                       6

Administration

         The Option Plan  (other than the  Automatic  Option  Grant  Program) is
administered  with respect to the Company's  executive  officers  subject to the
short-swing profit  liabilities of Section 16 of the Securities  Exchange Act of
1934  ("Section 16 Insiders") by the Primary Stock Option Plan  Committee of the
Board.  With  respect  to  all  other  participants,  the  Option  Plan  may  be
administered  by either the Primary  Stock Option Plan  Committee or the Special
Stock  Option  Plan  Administration  Committee,  a  committee  of  one  or  more
employee-Board  members  appointed by the Board.  Each of the committees will be
referred  to  in  this  summary  as  the  Plan  Administrator,   and  each  Plan
Administrator  will have complete  discretion  (subject to the provisions of the
Option Plan) to authorize  option  grants under the Option Plan within the scope
of its  administrative  jurisdiction.  However,  all grants under the  Automatic
Option Grant Program are to be made in strict  compliance with the provisions of
that program,  and no  administrative  discretion  will be exercised by the Plan
Administrator with respect to the grants made under that program.

Share Reserve

         The total  number of shares of Common Stock  issuable  over the term of
the Option Plan may not exceed 18,140,000 shares, (including the 2,500,000-share
increase  subject to approval by the  stockholders  as part of this Item No. 2).
However,  no  individual  participating  in the Option Plan may be granted stock
options for more than  3,000,000  shares in the  aggregate  over the term of the
Option Plan,  exclusive of any option  grants made to that  individual  prior to
January 1, 1994.  Should any option  terminate  prior to exercise  in full,  the
shares subject to the  unexercised  portion of that option will be available for
subsequent option grants. In addition, any unvested shares issued under the Plan
and subsequently  repurchased by the Company at the original exercise price paid
per share  pursuant to the  Company's  repurchase  rights under the Plan will be
added back to the number of shares of Common Stock  reserved for issuance  under
the Plan and will  accordingly be available for  reissuance  through one or more
subsequent option grants made under the Plan.

         As of March 17,  1997,  6,703,520  shares were  subject to  outstanding
option grants under the Option Plan,  3,433,176  shares  remained  available for
future grant (assuming  approval of this Item No. 2), and 8,003,304  shares have
been issued under the Option Plan. Several important features of the outstanding
options should be noted:

                  * No  outstanding  option has an exercise price per share less
than the fair market value per share of the Common Stock on the grant date.

                  *  Approximately  75% of the  outstanding  options are special
"evergreen"  options which are intended to maintain the optionee's holdings at a
sufficient  level to  provide a  meaningful  incentive  for such  individual  to
continue in the  Company's  employ.  These  evergreen  options  are  accordingly
granted to individuals  who already hold one or more  outstanding  options under
the Option Plan and utilize a special vesting schedule under which these options
will  not  become   exercisable   for  any  of  the  option   shares  until  the
thirty-seventh  (37th) month from the date of grant.  Once the evergreen  option
does  become  exercisable,  that  option  will vest in a series  of twelve  (12)
successive equal monthly  installments  over the optionee's  period of continued
employment  with  the  Company.   Accordingly,  a  substantial  portion  of  the
outstanding  options  will  provide no value or  benefit  to the option  holders
unless  those  individuals  make  a  long-term  commitment  to  continue  in the
Company's employ.

                                       7

Changes in Capitalization

         If any change is made to the  Common  Stock  issuable  under the Option
Plan (by reason of any merger, consolidation or reorganization of the Company or
any  recapitalization,  stock  split,  stock  dividend,  combination  of shares,
exchange of shares or other  similar  change  affecting the  outstanding  Common
Stock  without  the  Company's  receipt  of  consideration),   then  appropriate
adjustments  will be made to the  maximum  number  and/or  class  of  securities
available  for  issuance  under the  Option  Plan,  the number  and/or  class of
securities and price per share in effect under each outstanding option under the
Discretionary  Option  Grant  Program,  and the maximum  number  and/or class of
securities for which stock options may be granted to any one  participant  after
December 31, 1993. Under the Automatic Grant Program, the number and/or class of
securities  for which  automatic  option grants are  subsequently  to be made to
newly-elected  or  re-elected  non-employee  Board members and the number and/or
class of  securities  and price per share in effect under each  automatic  grant
outstanding would be similarly  adjusted.  All such adjustments will be designed
so as to preclude the enlargement or dilution of participant rights and benefits
under the Option Plan.

Valuation

         The fair market value per share of Common  Stock on any  relevant  date
under the Option Plan will be the closing  selling  price per share on that date
on the Nasdaq National Market.  On March 17, 1997, the closing selling price per
share was $29.00.


                       Discretionary Option Grant Program
Grants

         Under the Discretionary  Option Grant Program,  the Plan  Administrator
has complete discretion to determine the eligible individuals who are to receive
discretionary option grants, the time or times when those grants are to be made,
the number of shares subject to each such grant, the vesting schedule applicable
to the  grant,  the  status  of that  grant  as an  incentive  stock  option  or
non-statutory  option under the Federal tax laws and the remaining terms of each
such grant,  subject to the provisions of the Option Plan and applicable Federal
tax laws. All expenses incurred in administering the Option Plan will be paid by
the Company.

Price and Exercisability

         The   exercise   price  per  share  for  options   granted   under  the
Discretionary  Option Grant Program may not be less than 100% of the fair market
value per share of Common Stock on the grant date. No granted option will have a
term in excess of ten (10) years,  and each option will become  exercisable in a
series of installments over the optionee's period of service with the Company.

         The exercise price may be paid in cash or in shares of the Common Stock
of the Company.  Outstanding  options may also be  exercised  through a same-day
sale  program  pursuant  to which a  designated  brokerage  firm is to effect an
immediate  sale of the  shares  purchased  under the  option and pay over to the
Company, out of the sales proceeds available on the settlement date,  sufficient
funds to cover the exercise  price for the purchased  shares plus all applicable
withholding taxes.

         No  optionee  has any  stockholder  rights  with  respect to the option
shares until such optionee has exercised the option and paid the exercise  price
for the purchased  shares.  Options are generally not assignable or transferable
other  than by will  or the  laws of  inheritance  and,  during  the  optionee's
lifetime,  the option may be exercised only by such optionee.  However, the Plan
Administrator  may allow  non-statutory  options to be  transferred  or assigned
during  the  optionee's  lifetime  to  one or  more  members  of the  optionee's
immediate  family  or to a trust  established  exclusively  for one or more such
family  members,  to the extent such transfer or assignment is in furtherance of
the optionee's estate plan.

                                       8

Termination of Service

         Upon the  optionee's  cessation of employment or service,  the optionee
will have a limited  period of time in which to exercise his or her  outstanding
options for any shares in which the optionee is vested at that time. However, at
any time while the options remain outstanding,  the Plan Administrator will have
complete  discretion to extend the period following the optionee's  cessation of
employment  or  service  during  which  his or her  outstanding  options  may be
exercised.  The  Plan  Administrator  will  also  have  complete  discretion  to
accelerate the exercisability or vesting of those options in whole or in part at
any time.

Corporate Transaction

         Each outstanding  option under the  Discretionary  Option Grant Program
will  become  immediately  exercisable  for all of the  shares of  Common  Stock
subject to that option in the event of an  acquisition of the Company by merger,
consolidation  or asset  sale,  unless the  option is  assumed by the  successor
corporation.  Immediately  following the consummation of such  acquisition,  all
outstanding  options  will  terminate,  except  to  the  extent  assumed  by the
successor corporation (or its parent company).

Limited Stock Appreciation Rights

         Officers and  non-employee  Board members of the Company subject to the
short-swing  profit  restrictions of the Federal  securities laws may be granted
limited stock appreciation rights in tandem with their outstanding  options. Any
option  with such a limited  stock  appreciation  right  will  automatically  be
canceled upon the  completion of a hostile tender offer for more than 50% of the
Company's  outstanding  shares, and the optionee will in return be entitled to a
cash  distribution from the Company in an amount per canceled option share equal
to the excess of (i) the highest  reported  price per share of Common Stock paid
in the tender offer over (ii) the option exercise price payable per share.

                         Automatic Option Grant Program

Terms

         Under the Automatic  Option Grant Program,  non-employee  Board members
will receive  option  grants at specified  intervals  over their period of Board
service.  The terms and  conditions of these special grants may be summarized as
follows:

         1. Each  individual  who becomes a non-employee  Board member,  whether
through  election  by  the  stockholders  or  appointment  by  the  Board,  will
automatically be granted, at the time of such initial election or appointment, a
non-statutory  stock option to purchase  30,000 shares of Common Stock to become
exercisable in a series of four (4) successive  equal annual  installments  upon
the  optionee's  completion of each year of Board service over the four (4)-year
period measured from the grant date.

         2. On the date of each Annual Stockholders Meeting, each individual who
is  re-elected  as a  non-employee  Board member with at least six (6) months of
Board  service  will  receive  a  non-statutory  stock  option  to  purchase  an
additional  7,500  shares of Common  Stock to become 100%  exercisable  upon the
optionee's  completion of one (1) year of Board service  measured from the grant
date.

         3.  The  exercise  price  per  share  will be equal to 100% of the fair
market value per share of Common  Stock on the  automatic  grant date,  and each
automatic  option is to have a maximum term of ten (10) years measured from such
grant date.

                                       9
<PAGE>

         4. Each automatic  option will remain  exercisable  for a six (6) month
period  following  the  optionee's  termination  of service  as a Board  member.
However,  should the optionee die while  serving as a Board member or during the
six (6)-month period following his or her cessation of Board service,  then such
option will remain  exercisable for a twelve  (12)-month  period  following such
optionee's  death and may be  exercised by the  personal  representative  of the
optionee's  estate  or the  person  to whom  the  grant  is  transferred  by the
optionee's will or the laws of inheritance. In no event, however, may the option
be exercised after the expiration date of the option term. During the applicable
post-service  exercise period, the option may not be exercised for more than the
number of shares (if any) for which the option is exercisable at the time of the
optionee's cessation of Board service.

         5. Each automatic option will become immediately exercisable for all of
the  option  shares as  fully-vested  shares  of  Common  Stock in the event the
Company is acquired by merger, consolidation or asset sale or should there occur
certain other changes in control or ownership of the Company.

         6. Each  automatic  option  will  automatically  be  canceled  upon the
successful completion of a hostile tender offer, and the optionee will in return
be entitled to a cash  distribution  from the Company in an amount per  canceled
option share equal to the excess of (i) the highest  reported price per share of
Common  Stock paid in the tender  offer over (ii) the option  price  payable per
share.  Stockholder approval of this Item No. 2 will constitute  pre-approval of
each option subsequently granted with such an automatic  cancellation  provision
and  the  subsequent  cancellation  of  that  option  in  accordance  with  such
provision.

         7. The remaining  terms and conditions of each  automatic  option grant
will in general  conform to the terms  summarized  above for option  grants made
under the  Discretionary  Option Grant Program and will be incorporated into the
option agreement evidencing the automatic grant.

Options Granted

         The table below shows, as to each of the Named  Executive  Officers and
each of the indicated  groups,  the following  information with respect to stock
options granted during the period from January 1, 1996 to March 17, 1997 (i) the
number of shares of Common  Stock  subject to options  granted  under the Option
Plan during that period and (ii) the weighted average option price per share for
such options.  Typically options held by the Named Executive  Officers and other
current  executive  officers  do not  become  exercisable  for any of the option
shares until the  thirty-seventh  (37th) month following the date of grant. Each
option will thereupon  become  exercisable in a series of twelve (12) successive
equal monthly  installments over the optionee's  period of continued  employment
with the Company.  However,  of the 1,092,732 option shares granted to executive
officers  during  January 1, 1996 to March 17,  1997:  (i)  538,150  shares will
become  exercisable per the schedule noted above; (ii) 235,000 shares granted to
new  officers  will  vest  incrementally  over the next  four (4) years of their
continued service;  and (iii) 319,582 special retention grant shares will become
exercisable  at twelve (12) month  intervals  over a three to four year  period.
Over 75% of the options held by employees who are not executive  officers of the
Company have the same vesting schedule  (beginning in the 37th month) as applied
to the  executive  officers.  In  addition,  Messrs.  Barrett,  Eyre,  Federman,
Palevsky,  Sun and  Takebayashi,  as  non-employee  Board  members,  will,  upon
re-election  to the  Board  at the  Annual  Meeting,  receive  at  that  time an
automatic  option grant for 7,500 shares with an exercise  price per share equal
to the  closing  selling  price per share of Common  Stock on the grant date and
vesting as specified in the Automatic Option Grant Program.

Amendment and Termination of the Plan

         The Board may amend or modify  the Option  Plan in any or all  respects
whatsoever.   However,  certain  amendments  to  the  Option  Plan  may  require
stockholder approval pursuant to applicable laws or regulations.

         The Board may terminate the Option Plan at any time,  but in all events
the Option Plan will  terminate upon the earlier of January 22, 2002 or the date
all shares  available for issuance  under the Option Plan are issued or canceled
pursuant to the exercise or surrender of options  granted under the Option Plan.
Any options  outstanding at the time of the  termination of the Option Plan will
remain in force in accordance with the provisions of the instruments  evidencing
such grants.

Federal Tax Consequences

         Options  granted  under the Option Plan may be either  incentive  stock
options which satisfy the  requirements  of Section 422 of the Internal  Revenue
Code  or   non-statutory   options  which  are  not  intended  to  satisfy  such
requirements.  The  Federal  income tax  treatment  for the two types of options
differs as follows:

                                       11
<PAGE>

         Incentive  Options.  No taxable income is recognized by the optionee at
the time of the option grant,  and no taxable income is generally  recognized at
the time the option is exercised. The optionee will, however,  recognize taxable
income in the year in which the purchased  shares are sold or otherwise made the
subject of disposition.

         For  Federal  tax  purposes,  dispositions  are  divided  into  two (2)
categories:  qualifying and  disqualifying.  The optionee will make a qualifying
disposition of the purchased shares if the sale or disposition is made more than
two (2)  years  after the grant  date of the  option  and more than one (1) year
after the exercise  date. If the optionee  fails to satisfy  either of these two
holding periods prior to sale or disposition,  then a disqualifying  disposition
of the purchased shares will result.

         Upon a qualifying  disposition,  the optionee will recognize  long-term
capital  gain in an amount equal to the excess of (i) the amount  realized  upon
the sale or other  disposition  of the  purchased  shares over (ii) the exercise
price  paid  for the  shares.  If there is a  disqualifying  disposition  of the
shares,  then the  excess of (i) the fair  market  value of those  shares on the
exercise  date over (ii) the exercise  price paid for the shares will be taxable
as ordinary income to the optionee.  Any additional gain or loss recognized upon
the disposition will be recognized as a capital gain or loss by the optionee.

         If the optionee  makes a  disqualifying  disposition  of the  purchased
shares, the Company will be entitled to an income tax deduction, for the taxable
year in which  such  disposition  occurs,  equal to the  excess  of (i) the fair
market value of such shares on the date the option was  exercised  over (ii) the
exercise  price  paid  for  such  shares.  If the  optionee  makes a  qualifying
disposition  of the  purchased  shares,  the Company will not be entitled to any
income tax deduction.

         Non-statutory  Options.  No taxable income is recognized by an optionee
upon the grant of a non-statutory option. The optionee will in general recognize
ordinary income in the year in which the option is exercised equal to the excess
of the fair market value of the  purchased  shares on the exercise date over the
exercise price, and the optionee will be required to satisfy the tax withholding
requirements applicable to such income.

         The Company  will be entitled to an income tax  deduction  equal to the
amount of ordinary  income  recognized  by the optionee in  connection  with the
exercise of the non-statutory  option.  The deduction will in general be allowed
for the  taxable  year in  which  such  ordinary  income  is  recognized  by the
optionee.

         Stock  Appreciation  Rights. If an option granted under the Option Plan
is canceled for an  appreciation  distribution  paid in cash, the recipient will
generally realize ordinary income, equal in amount to the cash received, and the
Company will be entitled to a corresponding income tax deduction.

         Deductibility of Executive  Compensation.  The Company anticipates that
any compensation deemed paid by it in connection with disqualifying dispositions
of incentive  stock option  shares or  exercises of  non-statutory  options will
qualify as  performance-based  compensation  for purposes of Code Section 162(m)
and will not have to be taken into  account for  purposes of the one (1) million
dollar   limitation  per  covered   individual  on  the   deductibility  of  the
compensation paid to certain executive officers of the Company. Accordingly, all
compensation  deemed paid under the Option Plan will  remain  deductible  by the
Company without limitation under Code Section 162(m).

Accounting Treatment

         The Company's earnings per share is computed using the weighted average
number  of  shares  of  Common  Stock  outstanding  and  dilutive  common  stock
equivalents.  Common stock equivalents  include shares issuable upon the assumed
exercise of outstanding options reflected under the treasury stock method.

         Under  generally  accepted  accounting  principles,  the  grant  or the
exercise of options to purchase  shares of the  Company's  Common  Stock with an
exercise  price equal to the fair market value of the Company's  Common Stock on
the grant date does not generally  require a charge to the  Company's  earnings.
However,  the Company is  required  to  disclose  in the notes to the  Company's
financial statements the fair value of options granted under the Option Plan and
the pro forma impact on the  Company's  annual net income and earnings per share
as  though  the  computed  fair  value  of such  options  had  been  treated  as
compensation expense.

Recommendation of the Board of Directors

         The affirmative vote of a majority of the issued and outstanding shares
present or represented and entitled to vote at the 1997 Annual Meeting is sought
for  approval  of the  amendments  to the Option  Plan.  The Board of  Directors
believes that option grants under the Option Plan play an important  role in the
Company's  efforts to attract,  employ,  and retain  employees,  directors,  and
consultants  of  outstanding  ability.   Accordingly,  the  Board  of  Directors
recommends that the stockholders vote FOR this proposal.  If the stockholders do
not  approve  the  proposal,  then  any  options  granted  on the  basis  of the
2,500,000-share  increase  which  forms  part of this  proposal  will  terminate
without  becoming  exercisable  for any of the shares of Common Stock subject to
those options, and no further options will be granted on the basis of such share
increase.  In addition,  the non-employee Board members will not become eligible
to  participate  in the  Discretionary  Option Grant  Program,  and any unvested
shares  repurchased  by the Company at the option  exercise price paid per share
will not be added back to the share  reserve  for  reissuance.  The Option  Plan
will,  however,  continue to remain in effect, and option grants may continue to
be made  pursuant to the  provisions  of the Option Plan in effect  prior to the
amendments  summarized in this Item No. 2, until the available reserve of Common
Stock as last approved by the  stockholders  has been issued  pursuant to option
grants made under the Option Plan.

New Plan Benefits

         As of March 17, 1997,  no options have been granted on the basis of the
2,500,000-share increase which forms part of this Item No. 2.

                       ITEM NO. 3 -- APPROVAL OF AMENDMENT
                      TO 1988 EMPLOYEE STOCK PURCHASE PLAN

Introduction

         The  stockholders  are being  asked to vote on a proposal to approve an
amendment to the Company's  1988  Employee  Stock  Purchase Plan (the  "Purchase
Plan") which will (i) increase  the number of shares  available  for issuance by
750,000  shares of Common  Stock from  2,800,000  to  3,550,000  shares and (ii)
extend the  termination  date of the  Purchase  Plan from  December  31, 1998 to
December 31, 2001.

         The Board of Directors believes that it is in the best interests of the
Company's  stockholders  to increase the number of shares  reserved for issuance
under the  Purchase  Plan and to extend  the term of such plan so that  eligible
employees of the Company and its participating  affiliates will continue to have
the opportunity to acquire an equity interest in the Company and thereby further
align their interests with those of the stockholders.

         The Purchase  Plan was adopted by the Board of Directors on January 21,
1988, and was approved by the stockholders on June 7, 1988. On January 22, 1997,
the Board of Directors  adopted the  amendment to the Purchase Plan which is the
subject of this Item No. 3.

         The  terms  and  provisions  of the  Purchase  Plan,  as  amended,  are
summarized  below.  This  summary,  however,  does not  purport to be a complete
description  of the  Purchase  Plan.  Copies of the actual plan  document may be
obtained by any stockholder upon written request to the Secretary of the Company
at the corporate offices in San Jose, California.

Administration

         The Purchase  Plan will be  administered  by a committee of two or more
Board members appointed by the Board.  Effective  December 1, 1996, the Purchase
Plan will be administered  by the new Primary Stock Option Plan Committee.  Such
Committee,  as Plan  Administrator,  has full authority to adopt  administrative
rules and  procedures  and to interpret the provisions of the Purchase Plan. All
costs and expenses incurred in the  administration of the Purchase Plan are paid
by the Company without charge to participants.

Securities Subject to the Purchase Plan

         The  maximum  number  of shares  of  Common  Stock  that may be sold to
participants over the term of the Purchase Plan may not exceed 3,550,000 shares,
assuming stockholder approval of this Item No. 3. However, not more than 795,646
shares may be issued under the Purchase Plan after March 17, 1997.

         The shares of Common  Stock  issuable  under the  Purchase  Plan may be
either  shares newly issued by the Company or shares  reacquired by the Company,
including shares purchased on the open market.

                                       14
<PAGE>

         In the event any  change is made to the  Company's  outstanding  Common
Stock (whether by reason of any recapitalization,  stock dividend,  stock split,
combination  of  shares,  or other  similar  change in the  corporate  structure
effected   without  the  Company's   receipt  of   consideration),   appropriate
adjustments  will be made to (i) the class  and  maximum  number  of  securities
purchasable  under the  Purchase  Plan,  (ii) the class  and  maximum  number of
securities  purchasable  per participant on any one purchase date, and (iii) the
class and number of securities purchasable and the price per share payable under
each outstanding  purchase rights. Such adjustments will prevent any dilution or
enlargement of participant rights under the Purchase Plan.

Eligibility and Participation

         Any  individual  who is  employed  on a basis  under which he or she is
expected  to work more than  twenty  (20)  hours per week for more than five (5)
months  per  calendar  year in the employ of the  Company  or any  participating
parent or subsidiary  corporation  (including any corporation which subsequently
becomes  such at any time during the term of the  Purchase  Plan) is eligible to
participate in the Purchase Plan upon  commencement  of  employment.  Currently,
Komag Materials  Technology and Komag U.S.A.  (Malaysia) Sdn. are  participating
corporate affiliates.

         As of March 17, 1997,  2,754,354 shares of Common Stock had been issued
under the Purchase Plan,  and 795,646 shares were available for future  issuance
(assuming  stockholder  approval  of this Item No.  3).  As of March  17,  1997,
approximately 4,202 employees (including 15 executive officers) were eligible to
participate in the Purchase Plan.

Purchase Periods

         The  Purchase  Plan  will be  implemented  in a series  of  overlapping
purchase periods,  each to be of duration (not to exceed twenty-four (24) months
per  purchase  period)  as  determined  by the Plan  Administrator  prior to the
commencement  date of the purchase  period.  Purchase  periods may begin, at the
Plan  Administrator's  discretion,  on the first day or the first Monday of each
fiscal quarter or each alternate fiscal quarter. Accordingly, either four (4) or
two (2) separate  purchase periods may commence in each fiscal year during which
the Purchase Plan remains in existence.

         A  participant  will have a separate  purchase  right for each purchase
period in which he or she  participates.  The purchase  right will be granted on
the first day of the purchase period and will  automatically be exercised on the
last date of each successive three (3)-month or six (6)-month period within that
purchase  period  ("Purchase  Date").  An employee may  participate  in only one
purchase  period at a time.  Accordingly,  an employee  who wishes to join a new
purchase  period must withdraw from the current  purchase  period in which he or
she is participating.

Purchase Price

         The purchase  price of the Common Stock  acquired on each Purchase Date
will be equal to  eighty-five  percent (85%) of the lower of (i) the fair market
value per  share of Common  Stock on the date on which  such  purchase  right is
granted or (ii) the fair market  value on such  Purchase  Date.  The fair market
value of Common Stock on any relevant  date will be the closing  price per share
on such date as reported on the Nasdaq National Market. The fair market value on
March 17, 1997 was $29.00 per share.

                                       15
<PAGE>

Purchase Rights and Stock Purchases

         Each  participant  may  authorize  periodic  payroll  deductions in any
multiple  of one percent  (1%) (up to a maximum of ten percent  (10%)) of his or
her base pay during the  relevant  purchase  period for the  purchase  of Common
Stock under the Purchase Plan. On each Purchase Date, the payroll  deductions of
each participant  will be automatically  applied to the purchase of whole shares
of Common Stock at the purchase price in effect for that Purchase  Date.  Unless
the  participant's  purchase  right is terminated or the  participant  no longer
remains  eligible to participate in the Purchase Plan, any amount remaining in a
participant's  account  after  the  purchase  of whole  shares  will be held for
purchase of Common Stock on the next  quarterly  or  semi-annual  Purchase  Date
within the purchase  period.  The maximum  number of shares  purchasable  by the
participant  on any  Purchase  Date may not exceed  3,000  shares in the case of
quarterly  Purchase  Dates or 6,000 shares in the case of  semi-annual  Purchase
Dates.

Termination of Purchase Rights

         The  purchase  right  of a  participant  will  terminate  upon  (i) the
participant's  termination of employment or (ii) the  participant's  election to
withdraw from the Purchase Plan. Any payroll  deductions  which the  participant
may have made with respect to the terminated purchase right will be refunded.

Stockholder Rights

         No  participant  will have any  stockholder  rights with respect to the
shares  covered by his or her  purchase  rights  until the  shares are  actually
purchased on the participant's behalf. No adjustment will be made for dividends,
distributions  or other rights for which the record date is prior to the date of
such purchase.

Assignability

         No  purchase   rights  will  be  assignable  or   transferable  by  the
participant  except  by will or by laws of  inheritance.  The  purchase  rights,
during  the  lifetime  of the  participant,  will  be  exercisable  only  by the
participant.

Merger or Liquidation of Company

         In the event the Company or its stockholders enter into an agreement to
dispose of all or substantially  all of the assets or outstanding  capital stock
of the Company by means of a sale, merger or reorganization in which the Company
will not be the surviving corporation or in the event the Company is liquidated,
then all outstanding  purchase rights will, in connection with the  consummation
of such  transaction,  be exercised  immediately  prior to such  transaction  by
applying all payroll deductions  previously  collected from participants  during
the purchase period to the purchase of whole shares of Common Stock.

Amendment and Termination

         The Purchase Plan will  terminate  upon the earlier of (i) December 31,
2001  (assuming  stockholder  approval  of this  Item No. 3) or (ii) the date on
which  all  shares  available  for  issuance  thereunder  are sold  pursuant  to
exercised purchase rights.  However, the Board may at any time alter, suspend or
discontinue the Purchase Plan.

                                       16
<PAGE>

         The Board may not,  without  stockholder  approval,  (i)  increase  the
number of shares  issuable  under the Purchase Plan,  except in connection  with
certain  changes in the  Company's  capital  structure,  (ii) alter the purchase
price formula so as to reduce the purchase price or (iii) modify the eligibility
requirements for participation in the Purchase Plan.

New Plan Benefits

         As of March 17, 1997,  no purchase  rights had been  granted  under the
Purchase  Plan on the basis of the  750,000-share  increase  which forms part of
this Item No. 3.

Federal Tax Consequences

         The Purchase Plan is intended to be an "employee  stock  purchase plan"
within the meaning of Section 423 of the  Internal  Revenue  Code.  Under a plan
which so qualifies,  no taxable income will be recognized by a participant,  and
no  deductions  will be allowable  to the Company,  upon either the grant or the
exercise of the purchase  rights.  Taxable  income will not be recognized  until
there is a sale or other  disposition of the shares  acquired under the Purchase
Plan or in the event the participant should die while still owning the purchased
shares.

                                       17
<PAGE>

         If the participant sells or otherwise  disposes of the purchased shares
within  two (2) years  after his or her entry date into the  offering  period in
which such shares  were  acquired or within one (1) year after the date on which
those  shares were  actually  purchased,  then the  participant  will  recognize
ordinary income in the year of sale or disposition  equal to the amount by which
the fair market value of the shares on the purchase  date  exceeded the purchase
price paid for those  shares,  and the Company will be entitled to an income tax
deduction,  for the  taxable  year in which such  disposition  occurs,  equal in
amount to such excess.

         If the participant  sells or disposes of the purchased shares more than
two (2) years after his or her entry date into the offering  period in which the
shares were  acquired  and more than one year after the  purchase  date of those
shares,  then the participant will recognize ordinary income in the year of sale
or  disposition  equal to the lesser of (i) the amount by which the fair  market
value of the shares on the sale or disposition  date exceeded the purchase price
paid for those shares or (ii) fifteen  percent (15%) of the fair market value of
the  shares on the  participant's  entry  date into that  offering  period.  Any
additional gain upon the disposition will be taxed as a long-term  capital gain.
The Company will not be entitled to an income tax deduction with respect to such
disposition.

         If the  participant  still  owns the  purchased  shares  at the time of
death, the lesser of (i) the amount by which the fair market value of the shares
on the date of death exceeds the purchase price or (ii) fifteen percent (15%) of
the fair market  value of the shares on his or her entry date into the  offering
period in which those shares were acquired will  constitute  ordinary  income in
the year of death.

Accounting Treatment

         Under current  accounting rules, the issuance of Common Stock under the
Purchase Plan will not result in a compensation  expense  chargeable against the
Company's reported earnings. However, the Company must disclose, in notes the to
the  Company's  financial  statements,  the pro forma  impact which the purchase
rights  granted under the Purchase  Plan would have upon the Company's  reported
earnings  were the  value of  those  purchase  rights  treated  as  compensation
expense.

Recommendation of the Board of Directors

         The Company is seeking the affirmative vote of a majority of the issued
and  outstanding  shares present or represented and entitled to vote at the 1997
Annual Meeting for approval of the amendments to the Purchase Plan. The Board of
Directors  believes  that the  amendments  to the Purchase Plan are necessary in
order to  continue  to  provide  equity  incentives  to  attract  and retain the
services of high  quality  employees.  For this  reason,  the Board of Directors
recommends that the stockholders vote FOR this proposal.  If the stockholders do
not approve the  proposal,  then no  purchase  rights will be granted  under the
Purchase Plan on the basis of the 750,000-share  increase, and the Purchase Plan
will  continue in effect until the earlier of (i) December 31, 1998, or (ii) the
date on which the  available  reserve of Common Stock under the Purchase Plan as
last approved by the stockholders is issued.

                                  ITEM NO. 4 --
                 APPROVAL OF AMENDMENT TO MANAGEMENT BONUS PLAN

         The  stockholders  are  being  asked to  approve  an  amendment  to the
Company's Management Bonus Plan (the "Bonus Plan") which will change the formula
for calculating  the dollar amount of the bonus pool available for  distribution
each  year  so that  one  formula  will be in  effect  if the  Company's  actual
operating  income for the fiscal year equals or exceeds  66.67% of the operating
income  target set for that year and a second  formula  will be in effect  under
which a  smaller  pool  will be  available  for  distribution  in the  event the
Company's  actual  operating income does not reach 66.67% of the target for that
year.

         The  amendment  was  adopted by the Board of  Directors  on January 22,
1997,  subject  to  stockholder  approval  at the  Annual  Meeting.  Stockholder
approval is  necessary in order to assure that the  compensation  paid under the
Bonus Plan will  continue  to qualify as  performance-based  compensation  under
Internal  Revenue Code Section  162(m).  By reason of that Code  provision,  the
compensation  which the  Company  pays to  certain  executive  officers  will be
deductible for federal income tax purposes only to the extent that  compensation
does not exceed one (1) million  dollars per covered  individual  for the fiscal
year.   However,   any   compensation   which  qualifies  as   performance-based
compensation  under Code  Section  162(m)  will not be  subject  to this  dollar
limitation.

         The following is a summary of the principal  features of the Bonus Plan
as amended. The summary,  however, does not purport to be a complete description
of all the  provisions  of the Bonus Plan.  Any  stockholder  of the Company who
wishes to  obtain a copy of the  actual  plan  document  may do so upon  written
request to the Corporate  Secretary at the Company's principal executive offices
in San Jose, California.

Purpose

         The Bonus Plan will provide the Company's  executive officers and other
eligible  individuals with a meaningful incentive to contribute to the Company's
financial  success by  allowing  them to share in a portion of the  consolidated
operating  income of the  Company  and one or more  subsidiaries  of the Company
selected by the Compensation Committee within the first ninety (90) days of each
fiscal year.

Administration

         The Bonus Plan will be administered by the Compensation Committee. Each
Board  member  currently  serving on this  Committee  qualifies  as an  "outside
director"  pursuant to the  applicable  requirements  of Internal  Revenue  Code
Section 162(m).

Eligibility

         The individuals  eligible for  participation  in the Bonus Plan will be
limited to the Company's executive officers. However, the Compensation Committee
will have the authority, exercisable at the start of any fiscal year, to include
as participants for that fiscal year one or more employees in certain  specified
job grade levels who are not  executive  officers of the  Company.  In no event,
however,  will any individual be eligible to participate in the Bonus 

                                       19
<PAGE>

Plan for a particular fiscal year, unless that individual has completed at least
six (6) months of  employment  with the  Company or a  participating  subsidiary
prior to the end of that fiscal year.

         The actual  participants  for each  fiscal year will be selected by the
Compensation  Committee.  An executive officer, once selected,  will continue to
participate in each succeeding  fiscal year,  unless the Compensation  Committee
affirmatively  elects,  prior to the start of any fiscal  year,  to exclude that
individual from participation for one or more subsequent fiscal years.

         As of March 17, 1997, 15 executive officers and approximately 296 other
individuals in the specified job grade levels were eligible for participation in
the Bonus Plan.

Aggregate Bonus Pool

         The aggregate  bonus pool payable under the Bonus Plan each fiscal year
will not exceed seven  percent (7%) of the  operating  income of the Company and
the participating subsidiaries.  In no case, however, will the pool exceed eight
percent (8%) of Company's total consolidated  operating income for that year. In
each case,  the  calculations  of operating  income and  consolidated  operating
income will be in determined in accordance  with generally  accepted  accounting
principles,  adjusted to exclude the following:  (i) any amounts  accrued by the
Company or its subsidiaries  pursuant to management  bonus plans,  discretionary
bonus plans or cash profit sharing plans and related  employer payroll taxes for
such fiscal year, (ii) any discretionary or matching  contributions  made to the
Company's Savings and Deferred  Profit-Sharing Plan or to the Company's Deferred
Compensation Plan for such fiscal year, (iii) all items of gain, loss or expense
for such  fiscal year  determined  to be  extraordinary  or unusual in nature or
infrequent  in  occurrence or related to the disposal of a segment of a business
or related to a change in accounting principles, all as determined in accordance
with the standards  established by Opinion No. 30 of the  Accounting  Principles
Board (APB No. 30), (iv) all items of gain, loss or expense for such fiscal year
related  to  restructuring  charges of  subsidiaries  whose  operations  are not
included in Operating  Income for such fiscal year, (v) all items of gain,  loss
or expense for such fiscal year related to discontinued  operations which do not
qualify  as a segment of a  business  as  defined  under APB No. 30 and (vi) any
profit or loss attributable to the business operations of any entity acquired by
the Company during such fiscal year. Operating income will not be adjusted for a
minority interest holder's share of a consolidated subsidiary's operating income
or loss.

         The actual  percentage of operating income to be allocated to the bonus
pool for each fiscal year will be determined pursuant to the following formula:

                  X is the percentage of the operating income of the Company and
                  participating subsidiaries which is to comprise the bonus pool
                  for that year.

                  Y  is  the  actual   operating   income  of  the  Company  and
                  participating  subsidiaries for the fiscal year divided by the
                  operating income target established for the fiscal year by the
                  Compensation  Committee  not later than ninety (90) days after
                  the start of such fiscal year.

                  If Y is 0.6667 or greater,  then X = 9Y - 4

                  If Y is less than 0.6667,  then X = 3Y

                                       20
<PAGE>

                  No amount  will be paid  under the Bonus  Plan if Y is zero or
less.
         For example,  if actual  operating  income is at 66.67% of target,  the
bonus pool will be equal to 2% of that  operating  income.  If actual  operating
income were only  33.33% of target,  the bonus pool would be equal to 1% of that
operating income.

Individual Bonus Award

         The bonus pool for each fiscal year will be  allocated,  in  accordance
with the following  procedures,  to all active  participants who continue in the
Company's employ through the date the allocation is made.

         A. Each of the Company's  executive  officers will be assigned an index
which is the  product  of their  base  salary,  measured  as of the close of the
fiscal year for which the bonus  allocation is to be made,  times the applicable
multiplier. The multiplier for the President and Chief Executive Officer and for
the  Chairman  of the  Board  will  be  two  (2),  for  Senior  Vice  Presidents
one-point-five (1.5) and for other Vice Presidents one (1).

         B. Bonuses will be awarded to each executive officer by multiplying the
aggregate  bonus pool for the fiscal year by a fraction,  the numerator of which
will be the individual  officer's index and the denominator of which will be the
sum of the indices for all executive officers.

         C. The Compensation Committee may, in its sole judgment and discretion,
reduce the bonus allocation to any or all of the executive officers. In no event
will the bonus award  allocated  to any  participant  for any fiscal year exceed
five (5) million dollars.

         D. To the extent the bonus otherwise allocable to any executive officer
for a fiscal year is reduced by reason of the Compensation Committee's action or
the dollar  limitation on the maximum bonus award,  the unallocated  amount will
serve as a  separate  bonus  pool  which  may be  allocated  to  other  eligible
individuals  in  specified  job grades.  One or more  executive  officers of the
Company may make  recommendations  to the Chief Executive  Officer and President
and the Chairman of the Board with respect to the eligible  employees who should
share in that separate pool and the portion of such pool to be allocated to each
such individual.  The Chief Executive  Officer and President and the Chairman of
the Board will each review such  recommendations  and may, in their  discretion,
submit one or more of such  recommendations  (with such adjustments as they deem
appropriate) to the Compensation  Committee for  consideration.  On the basis of
such  recommendations,  the  Compensation  Committee may select one or more such
eligible  employees to share in the bonus pool and  determine the amount of such
pool to be allocated to each  selected  individual.  All  determinations  of the
Compensation Committee will be final.

         E. No bonus  payment  will be made to any  participant  who  leaves the
employ of the Company or a participating  subsidiary prior to the date the bonus
is allocated,  unless his or her  termination of employment  occurs by reason of
retirement  at or after age 65,  disability  or death.  In  addition,  the bonus
payable to a participant  who works part of the fiscal year in the employ of the
Company or any participating  subsidiary and the balance in the employ of one or
more of the Company's  subsidiaries  not  otherwise  covered by the Plan will be
pro-rated to reflect only the time such individual remained in the employ of the
Company or such participating subsidiary.

                                       21
<PAGE>

Payment

         The  bonus  will be paid in cash to each  eligible  participant  within
thirty  (30) days  after the  completion  of the annual  audit of the  Company's
financial statements by the Company's independent auditors.

Amendment and Termination

         The Board may at any time amend, suspend or terminate the Bonus Plan in
whole or in part.  However, no such action by the Board may adversely affect the
rights and interests of the participants and their beneficiaries with respect to
any earned but unpaid bonuses  outstanding at the time. All material  amendments
to the Bonus Plan will require stockholder approval.

Federal Tax Consequences

         Under  present  federal  income  tax  law,  participants  will  realize
ordinary income  immediately upon receipt of their bonus  distribution under the
Bonus Plan.  The Company  will be  entitled to an income tax  deduction,  in the
amount of such ordinary income,  for the fiscal year for which the bonus payment
is made,  provided the payment is made within two and one-half  months after the
close of that fiscal  year;  otherwise,  the payment will be  deductible  in the
succeeding  fiscal year.  The  deduction  will,  to the extent  attributable  to
bonuses paid to the Company's executive  officers,  be subject to the provisions
of Internal Revenue Code Section 162(m),  which limits the  deductibility of all
nonperformance-based  compensation  paid to certain  corporate  executives to $1
million per covered  individual.  However,  if the  amendment  to the Bonus Plan
which is the subject of this Item No. 4 is approved by the  stockholders  at the
Annual Meeting,  then all payments under the Plan should remain fully deductible
by the Company for federal  income tax purposes and should not be subject to the
limitations  of Section  162(m).  Prior to the amendment of the Bonus Plan,  the
Company had obtained a ruling from the Internal Revenue Service that the bonuses
payable to the  Company's  executive  officers  under the Plan would  qualify as
performance-based  compensation.  The Company  intends to apply to the  Internal
Revenue  Service for an update to that ruling which will cover the new amendment
to the Bonus Plan, if the amendment is approved at the Annual Meeting.

Recommendation of the Board of Directors

         Approval of the  amendment to the Bonus Plan  requires the  affirmative
vote of the  holders of a  majority  of the  shares of Common  Stock  present or
represented and entitled to vote at the Annual Meeting.  No amounts will be paid
under the Bonus Plan for the 1997  fiscal  year or any  subsequent  fiscal  year
unless the  stockholders  approve the amendment to Bonus Plan at the 1997 Annual
Meeting.  However,  whether or not such stockholder approval is obtained,  bonus
amounts  may become  payable  to one or more  executive  officers  and other key
employees  under  the  Company's  Discretionary  Bonus  Plan  which the Board of
Directors  implemented  in  December  1996 as a  special  retention-based  bonus
program to maintain a  competitive  level of total cash  compensation  for those
individuals  whose retention is essential to the Company's  long-term  financial
success.

         Because  the  Board of  Directors  believes  that the  Bonus  Plan is a
valuable incentive program which will serve to align the interests of management
with  those  of  the   stockholders   in  seeking  to  maximize  the   Company's
profitability,  the Board recommends a vote FOR the approval of the amendment to
the Bonus Plan.

Plan Benefits

         Bonuses  will  be paid  under  the  Bonus  Plan  only if the  Company's
operations  are  profitable.  No bonuses  were paid under the Bonus Plan for the
1996 fiscal year because the Company's actual operating income for that year was
less than 66.67% of the operating  income  target.  The bonuses which may become
payable for the 1997 fiscal year pursuant to the amended bonus formula in effect
under the Bonus Plan are not currently determinable.


                                  ITEM NO. 5 --
                      RATIFICATION OF INDEPENDENT AUDITORS

         The Company is asking the stockholders to ratify the selection of Ernst
& Young LLP as the  Company's  independent  auditors  for the fiscal year ending
December  28,  1997.  The  affirmative  vote of the holders of a majority of the
shares  represented  and voting at the Annual Meeting will be required to ratify
the selection of Ernst & Young LLP.

         In the event the stockholders fail to ratify the appointment, the Board
of Directors will  reconsider its selection.  Even if the selection is ratified,
the  Board  in  its  discretion  may  direct  the  appointment  of  a  different
independent  accounting firm at any time during the year if the Board feels that
such  a  change  would  be  in  the  best  interests  of  the  Company  and  its
stockholders.  Unless  otherwise  instructed,  the proxy  holders  will vote the
proxies  received by them FOR the ratification of the selection of Ernst & Young
LLP.

         Ernst & Young  LLP  has  audited  the  Company's  financial  statements
annually beginning in 1986.  Representatives of the firm, who are expected to be
present at the Annual Meeting,  will have the opportunity to make a statement if
they desire to do so, and will be available to respond to appropriate questions.

Recommendation of the Board of Directors

         The affirmative vote of a majority of the issued and outstanding voting
shares is sought for the ratification of the selection of Ernst & Young LLP. The
Board of Directors recommends that the stockholders vote FOR this proposal.

                      REPORT OF THE COMPENSATION COMMITTEE
                            ON EXECUTIVE COMPENSATION

         The Committee's members, Craig R. Barrett, Irwin Federman, Max Palevsky
and Masayoshi  Takebayashi,  are independent  directors who are not employees of
the Company and who qualify as outside  directors  under  Section  162(m) of the
Internal  Revenue  Code.  The  Committee  is  accountable  for the  approval  of
cash-based executive compensation programs that fairly compensate key executives
and employees and that relate the pay levels of officers to the  performance  of
the  Company.  Prior to December  1996,  the  Committee  also had the  exclusive
authority  to make option  grants under the  Company's  Stock Option Plan to the
Company's  executive  officers.  However,  as a result of the  November  1, 1996
amendments  to the Rule 16b-3 of the  Securities  and Exchange  Commission,  the
Board of Directors  created a special  committee of the Board, the Primary Stock
Option Plan Committee, to assume that authority.

Objectives of Executive Compensation Plans and Actions of the Committee

          The  Committee,  relying  on  research  performed  by  an  independent
compensation  consulting  firm and advice  from the  Company's  human  resources
department,  has  structured  compensation  incentives  for officers and certain
other key employees to optimize short-term and long-term  corporate  performance
for the benefit of the  Company's  stockholders,  customers,  employees  and the
communities in which the Company operates.  For comparison purposes, the Company
has identified a group of  high-performing  companies  ("peer  companies")  both
within and outside the Company's  industry.  The Company  competes with the peer
companies  for the  hiring  and  retention  of key  executives  and  accordingly
compares its  executive  compensation  practices to these  companies.  Each peer
company  shares at least one  attribute,  such as high  technology,  location or
size, with the Company.  Such  comparisons  also include the relative  financial
performance of the Company and the peer companies.  Since  executive  search and
retention is not industry  specific,  currently  only 3 of the 29 peer companies
are included in the NASDAQ Computer  Manufacturers Index, the Company's Industry
Index in the "Stock Performance Graph".

         In future fiscal years, the Committee may add or delete companies which
are to be  included  in the  group of peer  companies,  and may  take  different
measures  of   financial   performance   into   account  in  setting   executive
compensation.

         Base Salary

         The  Committee  intends that base salary be  sufficient  to attract and
retain  executives  of the  caliber  required to manage a company  that  employs
demanding  technology  in  a  competitive,  high  growth  market.  However,  the
Committee  also  intends that a  substantial  portion of each  executive's  cash
compensation be tied to Company  performance  through the Management Bonus Plan.
Accordingly,  the base  salaries of the  executive  officers are targeted at the
50th percentile of base salaries for similar positions among the peer companies,
subject to special adjustments for individual  qualifications.  Annual increases
in base salary will generally  reflect expected changes in salary levels at peer
companies.

         During 1996,  the salaries of Stephen C.  Johnson,  President and Chief
Executive Officer, and Tu Chen, Chairman of the Board, were at approximately the
fiftieth  percentile of salaries paid for executives in comparable  positions at
the peer companies  based on 1995  compensation  data. The salaries of the other
executive officers ranged from the second to the fourth quartiles for executives
in similar  positions  based on the  Committee's  judgment of each  individual's
performance.

                                       26

         Annual Incentive Bonus

         To complement base salary,  the Committee  adopted the Management Bonus
Plan (the "Bonus Plan") in March 1996 as an incentive  bonus program to continue
in  effect  from year to year for the  Company's  executive  officers  and other
eligible individuals. The principal features of the Bonus Plan are summarized in
Item No. 4 to this Proxy  Statement.  However,  no  bonuses  were paid under the
Bonus Plan for the 1996 fiscal year because the operating  income of the Company
and certain designated subsidiaries did not reach 66.67% of the operating income
target established by the Committee for that fiscal year.

         Discretionary Bonus Plan

         In December 1996, the Board of Directors  authorized the implementation
of the Discretionary Bonus Plan (the "Discretionary Plan") to be administered by
this  Committee.  The  purpose  of the  Discretionary  Plan is to assure  that a
competitive level of total cash  compensation is paid,  through a combination of
base salary and bonus awards to executives and other eligible  individuals whose
retention  is critical to the  Company's  financial  success.  Accordingly,  the
Committee will, with the assistance of the Company's management and such outside
compensation  specialists  as  the  Committee  deems  appropriate,  undertake  a
competitive  analysis of the Company's  compensation  each fiscal year to assure
that the compensation  levels for the Company's key employees remain competitive
with other opportunities  offered in the relevant  marketplace.  If the analysis
for any fiscal year suggests that the level of cash  compensation  for that year
is not competitive with the industry,  then a cash bonus pool for that year will
be  established  for   distribution   to  selected  key  employees.   The  bonus
distribution  will be targeted to those  employees  considered  essential to the
Company's  continued  financial  success who would  otherwise be  vulnerable  to
competitor  recruiting by offers of more attractive  compensation.  For the 1996
fiscal  year,  bonuses  in the  aggregate  amount of  $267,500  were paid to the
Company's executive officers under the Discretionary Plan.

         Stock Options

         Options are designed to align the interests of the  executive  officers
with  those of the  stockholders,  providing  each  officer  with a  significant
incentive to manage the Company from the long-term  perspective of an owner with
an equity  stake in the  business.  The stock option plan  encourages  long-term
retention  and  provides  rewards to  executives  and other  eligible  employees
commensurate with growth in stockholder value. It is the Committee's practice to
grant options to purchase shares at the market price on the date of grant with a
term of up to ten years.  The  majority  of options  granted  during 1996 to the
Company's  executive  officers will vest in twelve equal  monthly  installments,
beginning  with the  thirty-seventh  (37th)  month  following  the  grant  date.
Accordingly, these options will provide a return to the option recipient only if
he or she remains in the Company's employ and the market price of the underlying
shares of common stock appreciates.

         For the 1996 fiscal year, the Committee had the sole responsibility for
making option grants to the Company's  executive  officers.  The Committee  also
approved the guidelines for the option grants made to other key employees during
that fiscal year.  The number of option shares  awarded for the 1996 fiscal year
was based on several  factors.  First,  as a result of its review of competitive
market data, the Committee targeted total option grants for the 1996 fiscal year
between 3% and 3.5% of total shares outstanding. Actual options granted for that
fiscal year  totaled 3.1% of the weighted  average  number of shares  issued and
outstanding.  Based on subsequent  review of more recent  competitive  data, the
Committee  believes  that the target for total annual option grants may be below
current  industry  standards  and  is  reviewing  that  target.   Second,  since
competitive data on the number of options granted to specific  management levels
and key  individual  contributors  is typically  not  available,  the  Committee
established  guidelines  based upon internal  estimates of the number of options
required  to  attract  and  retain  these  employees.   Finally,  the  Committee
considered individual performance in making grants to specific executives. While
no explicit consideration was given to the number of unvested options held by an
individual  at the time the grant was made,  the  vesting  terms of the  options
typically granted annually to current employees,  which specify that the vesting
will take place  entirely  in the fourth year after the grant,  are  designed so
that the vesting will not overlap

                                       27

with previous options. In the case of three new officers, their new-hire options
will vest incrementally over the next four (4) years of their continued service.
In 1996, the Committee awarded stock options to purchase 43,500 shares of Common
Stock  each to Mr.  Johnson  and Dr.  Chen in  recognition  of  their  continued
importance to the Company's  success.  Option grants to other executive officers
ranged  from  11,100   shares  to  110,000   shares  based  on  their  level  of
responsibility and the Committee's assessment of their individual performance.

Compliance with Internal Revenue Code Section 162(m)

         As a result of Section 162(m) of the Internal  Revenue Code,  which was
enacted into law in 1993,  the Company will not be allowed a Federal  income tax
deduction  for  compensation  paid  to  certain  officers,  to the  extent  that
compensation  exceeds one (1) million  dollar per officer in any one year.  This
limitation will be in effect for each fiscal year of the Company beginning after
December  31,  1993  and  will  apply to all  compensation  paid to the  covered
executive officers which is not considered to be performance based. Compensation
which does qualify as  performance-based  compensation will not have to be taken
into account for purposes of this  limitation.  At the 1994 Annual Meeting,  the
Company obtained  stockholder  approval for certain  amendments to the Company's
Stock  Option Plan which were  designed to assure that any  compensation  deemed
paid in connection  with the exercise of stock  options  granted under that plan
will qualify as  performance-based  compensation.  In March 1996, the Bonus Plan
was restructured, effective with the 1996 fiscal year, so that the payments made
under that plan  would also  qualify  as  performance-based  compensation  under
Section  162(m).  The Bonus Plan was  approved by the  stockholders  at the 1996
Annual  Meeting,  and the Company  obtained a ruling from the  Internal  Revenue
Service that the payments under the Bonus Plan will qualify as performance-based
compensation.  If the  stockholders  approve the amendment to the Bonus Plan, as
described  in Item No. 4 in the Proxy  Statement,  at the Annual  Meeting,  then
future   payments   under  the  Bonus  Plan   should   continue  to  qualify  as
performance-based  compensation  which would not be subject to the Code  Section
162(m) limitation on deductibility.

         Other Plans

         All employees, including the Company's executive officers, are eligible
to participate in the Company's  Employee Stock Purchase Plan and, to the extent
that the  subsidiary  in which they are  employed  participate,  in its cash and
deferred profit sharing plans.

(1)      The option granted to each officer will not become  exercisable for any
         of the option shares prior to the officer's  completion of 36 months of
         service with the Company,  measured from the grant date.  Following the
         satisfaction  of such  service  requirement,  the  option  will  become
         exercisable  in a series of twelve  (12) equal and  successive  monthly
         installments upon the officer's  completion of each additional month of
         service thereafter.  Each option was granted on January 3, 1996 and has
         a maximum  term of 10 years,  subject to earlier  termination  upon the
         optionee's  cessation of service.  Each option will become  immediately
         exercisable  for all the  option  shares in the event  the  Company  is
         acquired  by a merger or asset  sale  (unless  the option is assumed or
         replaced  by the  acquiring  entity)  or in the  event  the  optionee's
         employment  terminates  by  reason of death,  permanent  disability  or
         retirement  at or after age 65.  Each option  includes a limited  stock
         appreciation  right  which  would  result in the  cancellation  of that
         option  upon a  take-over  of the  Company  effected  through a hostile
         tender  offer for more  than 50% of the  Company's  outstanding  Common
         Stock. In return,  the optionee will be entitled to a cash distribution
         from the  Company  per  canceled  option  share  equal  to the  highest
         reported  price paid per share of Common  Stock in such  tender  offer,
         less the option exercise price per share.

(2)      The  exercise  price may be paid in cash,  in  shares of the  Company's
         Common  Stock  valued at fair market  value on the  exercise  date,  or
         through a cashless exercise procedure  involving a same-day sale of the
         purchased shares.

(3)      There is no assurance provided to any executive  officer,  or any other
         holder  of the  Company's  securities,  that  the  actual  stock  price
         appreciation over the 10 year option term will be at the assumed 5% and
         10% levels or at any other  defined  level.  Unless the market price of
         the Common Stock  appreciates  over the option  term,  no value will be
         realized from the option grants made to the executive officers.

(4)      For  purposes  of such pro  forma  disclosure,  the fair  value of each
         option grant is estimated on the date of grant using the  Black-Scholes
         option pricing model with the following assumptions: risk-free interest
         rate of 6.1%;  volatility  factor of the  expected  market price of the
         Company's Common Stock of 60%; and a weighted-average  expected life of
         such options of 5.9 years.  There was no dividend yield included in the
         calculation   since   the   Company   does  not  pay   dividends.   The
         weighted-average  fair value of options granted to all employees during
         1996  was  $12.88.   For  officer   grants  of  January  3,  1996,  the
         weighted-average fair value of the options was $15.785.

Employment Contracts and Termination of Employment Agreements

         None of the Company's  executive  officers have employment or severance
agreements with the Company.

Certain Relationships and Related Transactions

         In March 1989,  the Company  formed a joint venture with Kobe Steel USA
Holdings  Incorporated  ("Kobe USA") whereby for $1,400,000 Kobe USA purchased a
45 percent equity ownership in the Company's then wholly-owned subsidiary, Komag
Material  Technology,  Incorporated  ("KMT").  Kobe USA,  along  with its parent
corporation,  Kobe  Steel,  Ltd.  ("Kobe  Steel")  (collectively  with Kobe USA,
"Kobe") is a former holder of greater than 5% of the Company's stock. From March
1989 through December 1990, the Company and Kobe USA have contributed $3,090,000
of additional  paid-in  capital and made loans totaling  $6,090,000  (which were
fully  repaid by the end of fiscal  1995) to KMT,  both in  proportion  to their
respective  ownership  interests  in KMT.  On  December  28,  1995,  the Company
purchased 25% of KMT's  outstanding  stock from Kobe,  thereby  reducing  Kobe's
ownership to 20%. The purchase price of this transaction was $6,750,000.

         Under the joint  venture  agreements,  Kobe agreed to supply  substrate
blanks to KMT and the Company agreed to purchase KMT's entire output of finished
substrates.  The Company made payments of  approximately  $43,168,551  to KMT in
1996 for the  purchase of finished  aluminum  substrates.  These  payments  were
determined  pursuant  to a  formula-based  price  whereby the prices paid by the
Company  may be  higher or lower  than  those  available  from  unrelated  third
parties.  In 1996  the  Company  also  purchased  approximately  $53,554,000  of
products  from Kobe Steel and its  subsidiaries  and  distributors.  The Company
believes that the terms and  conditions  for the above payments are as favorable
as could be obtained from unrelated third parties.

         Pursuant to the terms of a Common Stock Purchase Agreement between Kobe
USA and the Company  (the "Kobe  Agreement"),  in March 1990 Kobe USA  purchased
2,000,000 shares of the Company's Common Stock for $20,000,000.  Kobe has agreed
to limit its ownership of the Company's  total voting  securities to not greater
than twenty percent (20%),  except that under  circumstances such as a potential
change of control or the emergence of a larger stockholder,  Kobe has a right of
first refusal with respect to the issuance of new securities by the Company, and
is also  entitled to  consideration  as a future  joint  venture  partner of the
Company.  In addition,  the Kobe Agreement generally restricts the right of Kobe
to sell or transfer the shares acquired under the Kobe  Agreement.  Kobe is also
required  to vote its  shares  as  directed  by the  Board of  Directors  of the
Company,  subject  to  certain  exceptions,  such as  upon  the  liquidation  or
disposition of the Company.  Further,  so long as Kobe continues to own at least
2,000,000 shares of the Company's Common Stock, the Kobe Agreement provides that
the Board of Directors of the Company and its Nominating Committee are generally
required to facilitate the election of a designee of Kobe to the Company's Board
of Directors  and to the  Nominating  Committee.  See "Item No.  1--Election  of
Directors" above.

         The Company and Asahi Glass Co.,  Ltd.  ("Asahi"),  a former  holder of
greater  than 5% of the  Company's  stock,  also  entered  into a  Common  Stock
Purchase  Agreement (the "Asahi Agreement") for the purchase of 2,000,000 shares
of the  Company's  Common  Stock for  $20,000,000  in January,  1989.  The Asahi
Agreement was amended in March, 1990 to conform substantially with the terms and
conditions of the Kobe  Agreement.  Mr. Neil, a member of the Company's Board of
Directors, is an executive officer of Asahi Glass America,  Incorporated ("Asahi
America"),  an  affiliate  of Asahi  Glass  Co.  See "Item  No.  1--Election  of
Directors" above. In 1996, the Company purchased  approximately $58,000 worth of
equipment  from Asahi.  The Company  believes  that the terms and  conditions of
these  purchases  were as favorable as could be obtained  from  unrelated  third
parties.

                                       35
<PAGE>

         In 1996,  the Company  recorded sales of  approximately  $39,876,000 to
Asahi Komag Co., Ltd.  ("AKCL"),  a joint venture  between the Company and Asahi
that manufacturers thin-film media in Japan, and made purchases of approximately
$12,145,000  from AKCL.  The Company  believes that the terms and  conditions of
these  purchases  were as favorable as could be obtained  from  unrelated  third
parties.

         In September 1994, the Company  announced its  participation in Headway
Technologies,  Inc. ("Headway"),  a new company formed to research,  develop and
manufacture  advanced   magnetoresistive  ("MR")  heads  for  the  data  storage
industry.  Hewlett-Packard  Company  ("HP") and AKCL  provided  the initial cash
funding to Headway in exchange for equity interests. The Company and Asahi Glass
America,  Inc.,  a  wholly-owned  subsidiary  of Asahi,  licensed  to Headway MR
technology and  contributed  research and  production  equipment in exchange for
equity.  The total investment made or committed by the  above-mentioned  parties
approximated  $36,000,000  in cash and assets plus the  contribution  of certain
technology in exchange for  additional  equity  ownership.  As a result of these
transactions,  directly or indirectly  Asahi  contributed  $8,400,000  and had a
voting interest in Headway of less than 20%.  Effective  February 4, 1997, AKCL,
Asahi Glass America, Inc., HP and Komag sold all of their interest in Headway to
new investors. The Company retains no remaining interest in Headway.


Compliance with Section 16(a) Beneficial Ownership Reporting

         Section  16(a) of the  Securities  Exchange  Act of 1934  requires  the
Company's  directors and executive  officers,  and persons who own more than ten
percent of a registered class of the Company's equity  securities,  to file with
the Commission  initial reports of ownership and reports of changes in ownership
of common stock and other equity securities of the Company. Officers,  directors
and greater than ten percent stockholders are required by Commission regulations
to furnish the Company with copies of all Section 16(a) forms they file.

         To the Company's  knowledge,  based solely upon written  review of such
reports  furnished  to the  Company and  written  representations  that no other
reports were  required,  during the fiscal year ended  December  29,  1996,  all
Section  16(a)  filing  requirements   applicable  to  the  Company's  officers,
directors and greater than ten percent stockholders were met in a timely manner,
except that (i) Mr. Neil did not file a timely Form 4 report with respect to his
purchase of 1,000 shares of the Company's  common stock in August 1996, and (ii)
Mr. Wey did not file a timely Form 5 report  with  respect to his gifts of 1,494
shares of the Company's common stock made in January 1996. Mr. Neil subsequently
reported his purchase  transaction  on a Form 5 report timely filed for the 1996
fiscal  year,  and Mr. Wey  reported  his gift on a late Form 5 report  filed in
March 1997.

                         RESTATED 1987 STOCK OPTION PLAN

                      (Amended and Restated March 28, 1997)


                                   ARTICLE ONE

                               GENERAL PROVISIONS


       I.         PURPOSES OF THE PLAN

                  This  Restated 1987 Stock Option Plan (the "Plan") is intended
to promote the interests of Komag,  Incorporated,  a Delaware  corporation  (the
"Corporation"),  by  providing  a method  whereby  eligible  individuals  may be
offered   incentives  and  rewards  which  will  encourage  them  to  acquire  a
proprietary  interest,  or otherwise increase their proprietary interest, in the
Corporation and continue to render services to the Corporation (or its parent or
subsidiary corporations).

      II.         STRUCTURE OF THE PLAN

                  A.  Option  Programs.  The  Plan  shall  be  divided  into two
separate components: the Discretionary Option Grant Program described in Article
Two and the Automatic Option Grant Program described in Article Three. Under the
Discretionary Option Grant Program,  eligible individuals may, at the discretion
of the Plan Administrator, be granted options to purchase shares of Common Stock
in accordance  with the  provisions of Article Two.  Under the Automatic  Option
Grant Program, each eligible member of the Corporation's Board of Directors (the
"Board") will automatically receive an option grant to purchase shares of Common
Stock in accordance with the provisions of Article Three.

                  B. General  Provisions.  Unless the context clearly  indicates
otherwise,  the  provisions  of Articles One and Four of the Plan shall apply to
the  Discretionary  Option Grant Program and the Automatic  Option Grant Program
and shall accordingly govern the interests of all individuals under the Plan.

     III.         ADMINISTRATION OF THE PLAN

                  A.  The   Discretionary   Option   Grant   Program   shall  be
administered by one or more committees  comprised of Board members.  The primary
committee  (the  "Primary   Committee")  shall  be  comprised  of  two  or  more
non-employee Board members and shall



<PAGE>



have sole and exclusive  authority to grant stock options and stock appreciation
rights  under  the   Discretionary   Option   Grant   Program  to  officers  and
employee-directors   of  the  Corporation  subject  to  the  short-swing  profit
restrictions of the Federal  securities laws. Stock options may be granted under
the  Discretionary  Option Grant  Program to all other  eligible  employees  and
consultants by either the Primary  Committee or a second committee  comprised of
two or more employee-Board members (the "Secondary  Committee").  The members of
the Primary  Committee  and the  Secondary  Committee  shall each serve for such
period of time as the Board may determine and shall be subject to removal by the
Board at any time.

                  B. Subject to the limited  authority  provided  the  Secondary
Committee to effect option grants in accordance with the provisions of paragraph
III.A  of this  Article  One,  the  Primary  Committee  shall  serve as the Plan
Administrator  and shall have full power and  authority  (subject to the express
provisions of the  Discretionary  Option Grant  Program) to establish such rules
and regulations as it may deem appropriate for the proper administration of such
program and to make such  determinations  under the program and any  outstanding
option  as  it  may  deem   necessary  or  advisable.   Decisions  of  the  Plan
Administrator  shall be final and binding on all parties with an interest in the
Plan or any outstanding option under this Discretionary Option Grant Program.

                  C.  Administration of the Automatic Option Grant Program shall
be self-  executing  in  accordance  with the express  terms and  conditions  of
Article Three.

      IV.         ELIGIBILITY FOR OPTION GRANTS

                  A. The  persons  eligible to receive  options  pursuant to the
Discretionary Option Grant Program under Article Two of the Plan shall be

                          -  those  key   employees   (including   officers  and
         directors)   of  the   Corporation   (or  its   parent  or   subsidiary
         corporations)  who render services which tend to contribute  materially
         to  the  success  of the  Corporation  (or  its  parent  or  subsidiary
         corporations)  or which may  reasonably  be  anticipated  to contribute
         materially to the future success of the  Corporation  (or its parent or
         subsidiary corporations),

                          -  non-employee  Board  members  who  render  valuable
         services to the Corporation (or its parent or subsidiary corporations),
         and

                          - those  independent  contractors  and consultants who
         provide  valuable  services  to  the  Corporation  (or  its  parent  or
         subsidiary corporations).

                  B.  Non-employee  Board  members  shall  also be  eligible  to
receive automatic option grants under the provisions of Article Three.

                                       2.


<PAGE>





                  C. The Plan Administrator  shall have full authority to select
the eligible  individuals  who are to receive  option grants under the Plan, the
number of shares to be covered by each granted option, whether such option is to
be  an  incentive  stock  option   ("Incentive   Option")  which  satisfies  the
requirements  of Section 422 of the  Internal  Revenue  Code or a  non-statutory
option ("Non-Statutory Option") not intended to meet such requirements, the time
or times at which such option is to become  exercisable and the maximum term for
which the option is to be outstanding.

                  D. For purposes of the Plan, the following provisions shall be
applicable  in  determining  the  parent  and  subsidiary  corporations  of  the
Corporation:

                           Any  corporation  (other than the  Corporation) in an
         unbroken chain of  corporations  ending with the  Corporation  shall be
         considered to be a parent corporation of the Corporation, provided each
         such  corporation  in the unbroken  chain (other than the  Corporation)
         owns, at the time of the determination,  stock possessing fifty percent
         (50%) or more of the total  combined  voting  power of all  classes  of
         stock in one of the other corporations in such chain.

                           Each  corporation  (other than the Corporation) in an
         unbroken chain of corporations  beginning with the Corporation shall be
         considered  to be a subsidiary of the  Corporation,  provided each such
         corporation  (other than the last  corporation)  in the unbroken  chain
         owns, at the time of the determination,  stock possessing fifty percent
         (50%) or more of the total  combined  voting  power of all  classes  of
         stock in one of the other corporations in such chain.

       V.         STOCK SUBJECT TO THE PLAN

                  A. The stock  issuable  under the Plan  shall be shares of the
Corporation's  authorized but unissued or reacquired Common Stock. The aggregate
number of shares  which may be issued over the term of the Plan shall not exceed
18,140,000*  shares  (subject to adjustment from time to time in accordance with
paragraph V.D of this Article One).  Such share reserve  includes an increase of
2,500,000  shares  that  was adopted by the Board on March 28, 1997,  subject to
stockholder approval at the 1997 Annual Meeting.

- --------
*Adjusted to reflect (i) the  two-for-one  split of the Common Stock effected in
December 1995 and (ii) the 3,000,000-share  (post-split) increase adopted by the
Board in  January  1996 and  approved  by the  stockholders  at the 1996  Annual
Meeting.  In  no  event,  however,  shall  more  than  shares  of  Common  Stock
(post-split)  be  issuable  under the Plan  after  March 17,  1997,  subject  to
adjustment  under  paragraph  V.D of this  Article  One in the event of  certain
changes in the Corporation's capital structure.

                                       3.

                  B. In no event any one individual participating in the Plan be
granted stock options and separately  exercisable stock appreciation  rights for
more than  3,000,000  shares of Common Stock (as adjusted for the December  1995
split)  in the  aggregate  over  the  remaining  term of the  Plan,  subject  to
adjustment  from time to time in accordance  with  paragraph V.D of this Article
One. For purposes of such  limitation,  no stock  options or stock  appreciation
rights granted prior to January 1, 1994 shall be taken into account.

                  C.  Should an option be  terminated  for any  reason  prior to
exercise  in whole or in part,  the shares  subject to the portion of the option
not so exercised  shall be available  for  subsequent  option  grants under this
Plan.  In  addition,  unvested  shares  issued  under the Plan and  subsequently
repurchased by the  Corporation  at the original  exercise price paid per share,
pursuant to the  Corporation's  repurchase  rights under the Plan shall be added
back to the number of shares of Common Stock  reserved  for  issuance  under the
Plan and shall  accordingly  be  available  for  reissuance  through one or more
subsequent option grants under the Plan.  However,  shares subject to any option
or portion  thereof  cancelled in accordance with paragraph IV of Article Two or
paragraph  III of  Article  Three  and  shares  repurchased  by the  Corporation
pursuant to its  repurchase  rights  under the Plan shall not be  available  for
subsequent option grants under the Plan.

                  D.  In the  event  any  change  is made  to the  Common  Stock
issuable  under the Plan  (whether  by reason of (i)  merger,  consolidation  or
reorganization   or  (ii)   recapitalization,   stock  dividend,   stock  split,
combination of shares,  exchange of shares or other similar change affecting the
outstanding  Common Stock as a class  without  receipt of  consideration),  then
unless  such  change  results  in the  termination  of all  outstanding  options
pursuant to the  provisions  of  paragraph  III of Articles Two and Three of the
Plan,  appropriate  adjustments shall be made to (i) the aggregate number and/or
class of shares issuable under the Plan, (ii) the maximum number and/or class of
shares for which stock options and  separately  exercisable  stock  appreciation
rights may be granted to any one participant in the aggregate after December 31,
1993,  (iii) the  number  and/or  class of shares  and price per share in effect
under each outstanding option under the Discretionary Option Grant Program, (iv)
the  number  and/or  class of shares  per  non-employee  Board  member for which
automatic  option grants are  subsequently to be made under the Automatic Option
Grant Program,  and (v) the number and/or class of shares and price per share of
the Common  Stock in effect under each  automatic  grant  outstanding  under the
Automatic  Option  Grant  Program.  The  purpose  of  such  adjustments  to  the
outstanding  options shall be to preclude the  enlargement or dilution of rights
and benefits under such options.



                                       4.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM


       I.         TERMS AND CONDITIONS OF OPTIONS

                  Options  granted   pursuant  to  this  Article  Two  shall  be
authorized  by  action  of  the  Plan   Administrator   and  may,  at  the  Plan
Administrator's   discretion,  be  either  Incentive  Options  or  Non-Statutory
Options.  Individuals  who are not Employees  may only be granted  Non-Statutory
options.  The granted  options shall be evidenced by instruments in such form as
the Plan Administrator shall from time to time approve; provided,  however, that
each such instrument  shall comply with and incorporate the terms and conditions
specified  below.  Each  instrument  evidencing an Incentive  Option  shall,  in
addition,  be subject  to the  applicable  provisions  of  paragraph  II of this
Article Two.

                  A.       Option Price.

                           1. The option  price per share  shall be fixed by the
Plan Administrator.  In no event,  however,  shall the option price per share be
less  than one  hundred  percent  (100%) of the fair  market  value per share of
Common Stock on the date of the option grant.

                           2. The option price shall become immediately due upon
exercise of the option and shall,  subject to the  provisions of paragraph VI of
this Article Two and the instrument evidencing the grant, be payable as follows:

                                  (i) full payment in cash or check drawn to the
         Corporation's order;

                                  (ii) full  payment  in shares of Common  Stock
         held by the  optionee  for the  requisite  period  necessary to avoid a
         charge to the Corporation's  earnings for financial  reporting purposes
         and valued at fair market value on the  Exercise  Date (as such term is
         defined below) equal to the option price; or

                                  (iii) full payment  through a  combination  of
         shares of Common Stock held by the optionee  for the  requisite  period
         necessary to avoid a charge to the Corporation's earnings for financial
         reporting purposes and valued at fair market value on the Exercise Date
         and cash or check, equal in the aggregate to the option price.

                                  (iv) to the extent the option is exercised for
         vested   shares,   the  option   price  may  also  be  paid  through  a
         broker-dealer sale and

                                       5.


<PAGE>



         remittance  procedure  pursuant  to which the  optionee  shall  provide
         irrevocable instructions to (I) a Corporation-designated brokerage firm
         to effect the immediate  sale of the purchased  shares and remit to the
         Corporation, out of the sale proceeds available on the settlement date,
         an amount equal to the aggregate option price payable for the purchased
         shares  plus all  applicable  Federal and State  income and  employment
         taxes  required  to be withheld  by the  Corporation  by reason of such
         purchase and (II) the Corporation to deliver the  certificates  for the
         purchased shares directly to such brokerage firm.

                           For  purposes of this  subparagraph  2, the  Exercise
Date  shall  be the  date on which  notice  of the  exercise  of the  option  is
delivered  to the  Corporation.  Except to the  extent  the sale and  remittance
procedure is utilized in connection with the exercise of the option,  payment of
the option price for the purchased shares must accompany such notice.

                           3. The fair market  value of a share of Common  Stock
on any  relevant  date  under  subparagraph  1 or 2 above  (and  for  all  other
valuation  purposes  under the Plan) shall be determined in accordance  with the
following provisions:

                                  (i) If the Common  Stock is at the time traded
         on the Nasdaq National Market,  then the fair market value shall be the
         closing  selling  price  per  share  of  Common  Stock  on the  date in
         question,  as such price is reported  by the  National  Association  of
         Securities  Dealers  on the  Nasdaq  National  Market or any  successor
         system.  If there is no closing  selling  price for the Common Stock on
         the date in  question,  then the fair market value shall be the closing
         selling  price on the last  preceding  date for  which  such  quotation
         exists.

                                  (ii) If the Common Stock is at the time listed
         on either the New York Stock Exchange or the American  Stock  Exchange,
         then the fair market value shall be the closing selling price per share
         of Common Stock on the date in question on such exchange, as such price
         is officially  quoted in the  composite  tape of  transactions  on that
         exchange.  If there is no closing selling price for the Common Stock on
         the date in  question,  then the fair market value shall be the closing
         selling  price on the last  preceding  date for  which  such  quotation
         exists.

                  B.       Term and Exercise of Options.

                           Each option  granted  under this Article Two shall be
exercisable  at such time or times,  during such period,  and for such number of
shares as shall be  determined  by the Plan  Administrator  and set forth in the
instrument evidencing such option; provided,

                                       6.


<PAGE>



however, that no option granted under this Article Two shall have a maximum term
in excess of ten (10) years from the grant date.

                  C.       Limited Transferability of Options.

         During the lifetime of the  optionee,  the option shall be  exercisable
only by the optionee and shall not be assignable or transferable by the optionee
otherwise than by will or by the laws of descent and distribution  following the
optionee's  death.  However,  the  Plan  Administrator  may  grant  one or  more
Non-Statutory  Options under this Article Two which may, in connection  with the
optionee's  estate plan,  be assigned in whole or in part during the  optionee's
lifetime to one or more members of the optionee's immediate family or to a trust
established  exclusively  for one or more  such  family  members.  The  assigned
portion may only be exercised by the person or persons who acquire a proprietary
interest in the option pursuant to the assignment.  The terms  applicable to the
assigned portion shall be the same as those in effect for the option immediately
prior to such assignment and shall be set forth in such documents  issued to the
assignee as the Plan Administrator may deem appropriate.

                  D.       Termination of Service.

                           1. Should an optionee  cease to remain in Service for
any reason (including death,  permanent disability or retirement at or after age
65) while the holder of one or more outstanding options granted to such optionee
under the Plan,  then such  option or  options  shall not  (except to the extent
otherwise  provided pursuant to paragraph VII below) remain exercisable for more
than a twelve  (12)-month period (or such shorter period as is determined by the
Plan Administrator and set forth in the option agreement)  following the date of
cessation of Service;  provided,  however, that under no circumstances shall any
such option be  exercisable  after the specified  expiration  date of the option
term.  Except to the extent otherwise  provided  pursuant to subparagraph  I.D.4
below, each such option shall,  during such twelve (12)-month or shorter period,
be exercisable for any or all vested shares for which that option is exercisable
on the date of such  cessation of Service.  Upon the  expiration  of such twelve
(12)-month or shorter  period or (if earlier) upon the  expiration of the option
term, the option shall terminate and cease to be exercisable for any such vested
shares for which the option has not been exercised.  However,  the option shall,
immediately upon the optionee's cessation of Service,  terminate and cease to be
outstanding  with  respect to any  option  shares in which the  optionee  is not
otherwise  at that time vested or for which the option is not  otherwise at that
time exercisable.

                           2. Should the optionee die while in Service, or cease
to  remain  in  Service  and  thereafter  die  while  the  holder of one or more
outstanding  options  under the Plan,  each such option may be  exercised by the
personal  representative of the optionee's estate or by the person or persons to
whom the option is transferred  pursuant to the optionee's will or in accordance
with the laws of descent and  distribution  but, except to the extent  otherwise
provided pursuant to subparagraph I.D.4 below, only to the extent of the

                                       7.


<PAGE>



number of vested shares (if any) for which the option is exercisable on the date
of the optionee's  death. Such exercise must be effected prior to the earlier of
(i) the  first  anniversary  of the  date of the  optionee's  death  or (ii) the
specified expiration date of the option term. Upon the occurrence of the earlier
event, the option shall terminate and cease to be exercisable.

                           3. If (i) the  optionee's  Service is terminated  for
cause (including, but not limited to, any act of dishonesty, willful misconduct,
fraud or  embezzlement  or any  unauthorized  disclosure or use of  confidential
information or trade secrets) or (ii) the optionee makes or attempts to make any
unauthorized  use or disclosure of confidential  information or trade secrets of
the Corporation or its parent or subsidiary corporations, then in any such event
all outstanding  options granted the optionee under the Plan shall terminate and
cease to be  exercisable  immediately  upon such  cessation  of  Service  or (if
earlier) upon such  unauthorized  use or disclosure  of  confidential  or secret
information or attempt thereat.

                           4.  The  Plan   Administrator   shall  have  complete
discretion,  exercisable either at the time the option is granted or at the time
the optionee  dies,  retires at or after age 65, or ceases to remain in Service,
to  establish as a provision  applicable  to the exercise of one or more options
granted  under  the Plan  that  during  the  limited  period  of  exercisability
following death,  retirement at or after age 65, or cessation of Employee status
as provided in  subparagraph  I.D.1 or I.D.2 above,  the option may be exercised
not only with respect to the number of vested shares for which it is exercisable
at the time of the optionee's cessation of Service, but also with respect to one
or more  subsequent  installments  in which the  optionee  would have  otherwise
vested had such cessation of Service not occurred.

                           5. For purposes of the  foregoing  provisions of this
paragraph I.D (and all other provisions of the Plan),

                           - The  optionee  shall be  deemed  to  remain  in the
         Service  of the  Corporation  for so long as  such  individual  renders
         services  on a  periodic  basis to the  Corporation  (or any  parent or
         subsidiary  corporation) in the capacity of an Employee, a non-employee
         member of the Board or an independent consultant or advisor.

                           - The optionee  shall be considered to be an Employee
         for so long as such individual remains in the employ of the Corporation
         or one or more of its parent or subsidiary corporations, subject to the
         control and  direction  of the  employer  not only as to the work to be
         performed but also as to the manner and method of performance.


                                       8.

                  D.       Stockholder Rights.

                           An option  holder  shall have none of the rights of a
stockholder  with  respect  to any  shares  covered  by the  option  until  such
individual  shall have  exercised  the  option,  paid the option  price and been
issued a stock certificate for the purchased shares. No adjustment shall be made
for  dividends  or  distributions  (whether  paid in cash,  securities  or other
property)  for which the record date is prior to the date the stock  certificate
is issued.

                  E.       Repurchase Rights.

                           The shares of Common Stock acquired upon the exercise
of options  granted  under this Article Two may be subject to  repurchase by the
Corporation in accordance with the following provisions:

                           The Plan  Administrator  shall have the discretion to
authorize  the  issuance of unvested  shares of Common  Stock under this Article
Two. Should the Optionee cease Service while holding such unvested  shares,  the
Corporation  shall  have the right to  repurchase  any or all of those  unvested
shares at the option price paid per share.  The terms and conditions  upon which
such repurchase  right shall be exercisable  (including the period and procedure
for exercise and the  appropriate  vesting  schedule for the  purchased  shares)
shall be established by the Plan  Administrator  and set forth in the instrument
evidencing such repurchase right.

                           All  of  the  Corporation's   outstanding  repurchase
rights shall automatically  terminate, and all shares subject to such terminated
rights shall  immediately  vest in full,  upon the  occurrence  of any Corporate
Transaction  under paragraph III of this Article Two, except to the extent:  (i)
any such  repurchase  right is to be assigned to the successor  corporation  (or
parent  thereof)  in  connection  with the  Corporate  Transaction  or (ii) such
termination is precluded by other limitations  imposed by the Plan Administrator
at the time the repurchase right is issued.

                           The Plan  Administrator  shall have the discretionary
authority,  exercisable  either  before or after  the  optionee's  cessation  of
Service, to cancel the Corporation's  outstanding repurchase rights with respect
to one or more  shares  purchased  or  purchasable  by the  optionee  under this
Article Two and thereby accelerate the vesting of such shares in connection with
the optionee's cessation of Service.

      II.         INCENTIVE OPTIONS

                  The terms and conditions  specified  below shall be applicable
to all Incentive  Options granted under this Article Two.  Incentive Options may
only be granted to individuals who are Employees. Options which are specifically
designated as "non-qualified"

                                       9.


<PAGE>



or  "non-statutory"  options  when issued under the Plan shall not be subject to
such terms and conditions:

                  A.  Option  Price.  The  option  price per share of the Common
Stock subject to an Incentive  Option shall in no event be less than one hundred
percent  (100%) of the fair market  value of a share of Common Stock on the date
of grant.

                  B.  Dollar   Limitation.   The  aggregate  fair  market  value
(determined as of the respective date or dates of grant) of the shares of Common
Stock for which one or more options  granted to any employee  under the Plan (or
any  other  option  plan  of  the   Corporation  or  any  parent  or  subsidiary
corporation)  may for the first time become  exercisable  as  Incentive  Options
during  any one (1)  calendar  year  shall  not  exceed  the sum of One  Hundred
Thousand  Dollars  ($100,000).  To the extent the employee holds two (2) or more
such options  which become  exercisable  for the first time in the same calendar
year,  the  foregoing  limitation  on the  exercisability  of  such  options  as
Incentive  Options  shall be  applied  on the basis of the  order in which  such
options are granted.

                  C. 10%  Stockholder.  If any  individual  to whom an Incentive
Option is granted is the owner of stock (as  determined  under Section 424(d) of
the Internal  Revenue Code)  possessing 10% or more of the total combined voting
power of all  classes  of stock of the  Corporation  or any one of its parent or
subsidiary corporations,  then the option price per share shall not be less than
one hundred and ten percent  (110%) of the fair market value per share of Common
Stock on the grant  date,  and the option  term shall not exceed five (5) years,
measured from the grant date.

                  Except  as  modified  by  the  preceding  provisions  of  this
paragraph  II, the  provisions  of Articles  One, Two and Four of the Plan shall
apply to all Incentive Options granted hereunder.

     III.         CORPORATE TRANSACTIONS

                  A. In the event of any of the  following  stockholder-approved
transactions (a "Corporate Transaction"):

                                  (i) a  merger  or  acquisition  in  which  the
         Corporation is not the surviving  entity,  except for a transaction the
         principal  purpose of which is to change the State of the Corporation's
         incorporation,

                                  (ii) the sale,  transfer or other  disposition
         of all or substantially all of the assets of the Corporation, or

                                  (iii)   any   reverse   merger  in  which  the
         Corporation is the surviving entity,


                                       10.


<PAGE>



                           then each option  outstanding  under this Article Two
shall automatically become exercisable,  during the five (5) business day period
immediately prior to the specified effective date for the Corporate Transaction,
with respect to the full number of shares of Common Stock purchasable under such
option  and may be  exercised  for all or any  portion  of such  shares as fully
vested shares of Common Stock. An outstanding option under the Plan shall not be
so accelerated,  however, if and to the extent (i) such option is, in connection
with  the  Corporate  Transaction,   either  to  be  assumed  by  the  successor
corporation  or  parent  thereof  or be  replaced  with a  comparable  option to
purchase  shares of the capital  stock of the  successor  corporation  or parent
thereof or (ii) the acceleration of such option is subject to other  limitations
imposed by the Plan Administrator at the time of grant.

                  B.  Immediately  following the  consummation  of the Corporate
Transaction,  all  outstanding  options under the Plan shall,  to the extent not
previously  exercised  or assumed  by the  successor  corporation  or its parent
company, terminate and cease to be exercisable.

                  C. Each  outstanding  option  under this  Article Two which is
assumed in connection with the Corporate Transaction or is otherwise to continue
in effect shall be  appropriately  adjusted,  immediately  after such  Corporate
Transaction,  to apply and pertain to the number and class of  securities  which
would have been issuable, in consummation of such Corporate  Transaction,  to an
actual  holder of the same  number of shares of Common  Stock as are  subject to
such  option  immediately  prior  to  such  Corporate  Transaction.  Appropriate
adjustments  shall also be made to the option price payable per share,  provided
the aggregate option price payable for such securities shall remain the same. In
addition,  the class and number of securities  available for issuance  under the
Plan  following  the  consummation  of  the  Corporate   Transaction   shall  be
appropriately adjusted.

                  D.  The  portion  of  any  Incentive  Option   accelerated  in
connection with a Corporate  Transaction  shall remain subject to the applicable
limitations of paragraph II.B.

                  E. Option grants under this Article Two shall in no way affect
the right of the  Corporation  to adjust,  reclassify,  reorganize  or otherwise
change its capital or business  structure  or to merge,  consolidate,  dissolve,
liquidate or sell or transfer all or any part of its business or assets.

      IV.         STOCK APPRECIATION RIGHTS

                  A. Officers and non-employee  Board members of the Corporation
subject to the short-swing  profit  restrictions of the Federal  securities laws
may, in the Plan  Administrator's  sole  discretion,  be granted  limited  stock
appreciation  rights in tandem with their outstanding options under this Article
Two. Upon the  occurrence of a Hostile  Take-Over effected at any time after the
Corporation's  outstanding Common Stock is registered under Section 12(g) of the
Exchange Act, each outstanding option with such a limited stock

                                       11.


<PAGE>



appreciation  right shall  automatically  be cancelled and the optionee shall in
return be  entitled to a cash  distribution  from the  Corporation  in an amount
equal to the excess of (i) the Take-Over  Price of the shares of Common Stock at
the time subject to the cancelled option (whether or not the option is otherwise
at the time exercisable for such shares) over (ii) the aggregate  exercise price
payable for such shares.  The cash  distribution  payable upon such cancellation
shall be made within five (5) days  following  the  consummation  of the Hostile
Take-Over.  The Plan Administrator  shall  pre-approve,  at the time the limited
right is granted,  the subsequent  exercise of that right in accordance with the
terms of the grant and the provisions of this Section IV. No additional approval
of the Plan  Administrator  or the Board  shall be  required  at the time of the
actual option cancellation and cash distribution.

                  B. For purposes of paragraph  IV.A, the following  definitions
shall be in effect:

                           A Hostile  Take-Over  shall be deemed to occur in the
         event  any  person  or  related  group  of  persons   (other  than  the
         Corporation  or a person  that  directly  or  indirectly  controls,  is
         controlled  by,  or is under  common  control  with,  the  Corporation)
         directly  or  indirectly  acquires  beneficial  ownership  (within  the
         meaning of Rule 13d-3 of the  Exchange  Act) of  securities  possessing
         more than fifty percent (50%) of the total combined voting power of the
         Corporation's  outstanding  securities pursuant to a tender or exchange
         offer which the Board does not recommend the Corporation's stockholders
         to accept.

                           The  Take-Over  Price per share shall be deemed to be
         equal to the greater of (a) the fair market value per share on the date
         of cancellation,  as determined pursuant to the valuation provisions of
         subparagraph I.A.3, or (b) the highest reported price per share paid in
         effecting such Hostile TakeOver. However, if the cancelled option is an
         Incentive  Option,  the Take-Over Price shall not exceed the clause (a)
         price per share.

                  C. The shares of Common Stock subject to any option  cancelled
for an  appreciation  distribution  pursuant  to this  paragraph  V shall not be
available for subsequent option grant under the Plan.

       V.         EXTENSION OF EXERCISE PERIOD

                  The Plan  Administrator  shall have full power and  authority,
exercisable from time to time in its sole discretion,  to extend,  either at the
time the option is granted or at any time while such option remains outstanding,
the period of time for which the option is to remain  exercisable  following the
optionee's  cessation of Service or death from the twelve  (12)-month or shorter
period set forth in the option agreement to such greater period of

                                       12.


<PAGE>



time as the Plan Administrator shall deem appropriate;  provided,  however, that
in no event shall such option be exercisable after the specified expiration date
of the option term.


                                       13.

                                  ARTICLE THREE

                         AUTOMATIC OPTION GRANT PROGRAM


        I.        ELIGIBILITY

                  The individuals  eligible to receive  automatic  option grants
pursuant  to the  provisions  of this  Article  Three  shall be  limited  to the
following:

                                  (i) each individual  serving as a non-employee
         member of the Board on January 24,  1995,  the  effective  date of this
         Automatic Option Grant Program (the "Effective Date"); and

                                  (ii) each individual who is first appointed or
         elected as a non-employee  Board member at any time after the Effective
         Date.

       II.        TERMS AND CONDITIONS OF AUTOMATIC OPTION GRANTS

                  A. Grant Dates.  Option grants will be made under this Article
Three on the dates specified below:

                                  (i)  Each   individual  who  first  becomes  a
         non-employee Board member at any time after the Effective Date, whether
         through  election  at  an  Annual   Stockholders   Meeting  or  through
         appointment by the Board, shall  automatically be granted,  at the time
         of such initial  election or  appointment,  a  Non-Statutory  Option to
         purchase 30,000 shares of Common Stock upon the terms and conditions of
         this Article Three. The size of such grant has been adjusted to reflect
         the  two-for-one  split of the Common Stock which  occurred in December
         1995,  but then reduced by  twenty-five  percent  (25%) to effect a net
         adjustment on a 1.5-for-one basis.

                                  (ii) On the date of each  Annual  Stockholders
         Meeting,  beginning  with the 1995 Annual  Stockholders  Meeting,  each
         individual  who is at the time elected or  reelected as a  non-employee
         member  of  the  Board  shall   receive  an   additional   grant  of  a
         Non-Statutory  Option  under the Plan to purchase  7,500  shares of the
         Common Stock,  provided such  individual has been a member of the Board
         for at least six (6) months.  The size of such grant has been  adjusted
         to reflect the two-for-one  split of the Common Stock which occurred in
         December 1995, but then reduced by twenty-five  percent (25%) to effect
         a net adjustment on a 1.5-for-one basis.

                  The applicable 30,000-share and 7,500-share limitations on the
automatic  option  grants to be made to  non-employee  Board  members under this
Article Three shall

                                       14.


<PAGE>



be subject to periodic  adjustment  pursuant  to the  applicable  provisions  of
paragraph V.C of Article One.

                  B. Exercise Price. The exercise price per share shall be equal
to one hundred percent (100%) of the fair market value per share of Common Stock
on the automatic grant date.

                  C.       Payment.

                           The  exercise  price  shall be  payable in one of the
alternative forms specified below:

                                  (i) full payment in cash or check made payable
         to the Corporation's order;

                                  (ii) full  payment  in shares of Common  Stock
         held for the  requisite  period  necessary  to  avoid a  charge  to the
         Corporation's  reported earnings and valued at fair market value on the
         Exercise Date (as such term is defined below); or

                                  (iii) full payment in a combination  of shares
         of Common  Stock held for the  requisite  period  necessary  to avoid a
         charge to the Corporation's reported earnings and valued at fair market
         value  on  the  Exercise   Date  and  cash  or  check  payable  to  the
         Corporation's order.

                                  (iv) the option price may also be paid through
         a  broker-dealer  sale and remittance  procedure  pursuant to which the
         optionee   shall   provide   irrevocable    instructions   to   (I)   a
         Corporation-designated  brokerage  firm to effect the immediate sale of
         the  purchased  shares  and remit to the  Corporation,  out of the sale
         proceeds  available  on the  settlement  date,  an amount  equal to the
         aggregate  option  price  payable  for the  purchased  shares  plus all
         applicable Federal and State income and employment taxes required to be
         withheld by the  Corporation  by reason of such  purchase  and (II) the
         Corporation  to  deliver  the  certificates  for the  purchased  shares
         directly to such brokerage firm.

                  For purposes of this subparagraph,  the Exercise Date shall be
the date on which notice of the option exercise is delivered to the Corporation,
and the fair market value per share of Common  Stock on any relevant  date shall
be determined in accordance  with the  provisions of paragraph  I.A.3 of Article
Two. Except to the extent the sale and remittance  procedure  specified above is
utilized for the exercise of the option,  payment of the exercise  price for the
purchased shares must accompany such notice.


                                       15.

                  D. Option Term.  Each automatic grant under this Article Three
shall have a maximum term of ten (10) years  measured from the  automatic  grant
date.

                  E. Exercisability.  The initial  30,000-share  automatic grant
made to each  newly-elected or  newly-appointed  non-employee Board member shall
become exercisable for the option shares in four (4) installments as follows:

                                  (i) The option  shall become  exercisable  for
         twenty- five percent (25%) of the option shares upon the  completion of
         twelve (12) months of Board service  measured from the automatic  grant
         date.

                                  (ii) The option shall become  exercisable  for
         an additional  twenty-five  percent (25%) of the option shares upon the
         completion of  twenty-four  (24) months of Board service  measured from
         the automatic grant date.

                                  (iii) The option shall become  exercisable for
         an additional  twenty-five  percent (25%) of the option shares upon the
         completion of thirty-six (36) months of Board service measured from the
         automatic grant date.

                                  (iv) The option shall become  exercisable  for
         the final  twenty-five  percent  (25%) of the  option  shares  upon the
         completion of  forty-eight  (48) months of Board service  measured from
         the automatic grant date.

                           The  annual  7,500-share  option  grant  made to each
re-elected  non-  employee  Board member shall  become  exercisable  for all the
option  shares  upon the  optionee's  completion  of twelve (12) months of Board
service measured from the automatic grant date.

                           As the  option  becomes  exercisable  for one or more
installments of the option shares, those installments shall accumulate,  and the
option shall  remain  exercisable  for the  accumulated  installments  until the
expiration or sooner termination of the option term. The option,  however, shall
not become exercisable for any additional option shares following the optionee's
cessation  of Board  service,  except to the extent the option is  otherwise  to
become  exercisable  in accordance  with the provisions of paragraph III of this
Article Three.

                  F. Limited  Transferability of Options. During the lifetime of
the optionee, the option shall only be exercisable by the optionee and shall not
be assignable or transferable  by the optionee  otherwise than by will or the by
the laws of descent and distribution  following the optionee's  death.  However,
each option  granted under this  Automatic  Option Grant Program on or after the
date of the 1997 Annual Stockholders  Meeting shall be assignable in whole or in
part by the optionee during his or her lifetime,

                                       16.


<PAGE>



but only to the extent such assignment is made in connection with the optionee's
estate plan to one or more members of the  optionee's  immediate  family or to a
trust established  exclusively for one or more such family members. The assigned
portion may only be exercised by the person or persons who acquire a proprietary
interest in the option pursuant to the assignment.  The terms  applicable to the
assigned portion shall be the same as those in effect for the option immediately
prior to such assignment and shall be set forth in such documents  issued to the
assignee as the Plan Administrator may deem appropriate.

                  G.       Effect of Termination of Board Membership.

                           1. Should the optionee cease to be a Board member for
any reason (other than death) while holding an automatic option grant under this
Article Three,  then such optionee shall have a six (6)-month  period  following
the date of such cessation of Board  membership in which to exercise such option
for any or all of the shares of Common Stock for which the option is exercisable
at the time the optionee ceases service as a Board member.

                           2. Should the optionee  die while  serving as a Board
member or during the six  (6)-month  period  following  his or her  cessation of
Board service, then the option may subsequently be exercised,  for any or all of
the shares of Common  Stock for which the option is  exercisable  at the time of
the optionee's cessation of Board membership,  by the personal representative of
the  optionee's  estate  or by the  person  or  persons  to whom the  option  is
transferred  pursuant to the optionee's  will or in accordance  with the laws of
descent and distribution.  Any such exercise must, however,  occur within twelve
(12) months after the date of the optionee's death.

                           3. In no event shall any  automatic  grant under this
Article Three remain exercisable after the specified  expiration date of the ten
(10)-year option term. Upon the expiration of the applicable  exercise period in
accordance with  subparagraphs 1 and 2 above or (if earlier) upon the expiration
of the ten (10)-year  option term, the automatic grant shall terminate and cease
to be exercisable.

                  H. Stockholder Rights. The holder of an automatic option grant
under this Article  Three shall have no  stockholder  rights with respect to any
shares  covered by such option until such  individual  shall have  exercised the
option, paid the exercise price for the purchased shares and been issued a stock
certificate for such shares.

                  I. Remaining Terms. The remaining terms and conditions of each
automatic  option  grant  shall be as set forth in the  prototype  Non-statutory
Stock Option Agreement attached as Exhibit A to the Plan.


                                       17.

      III.        CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-
                  OVER

                  A. In connection with any Corporate  Transaction (as such term
is defined in paragraph III of Article Two, above),  the  exercisability of each
automatic option grant outstanding under this Article Three shall  automatically
accelerate  so that each such option shall,  immediately  prior to the specified
effective  date for the Corporate  Transaction,  become fully  exercisable  with
respect  to the total  number of shares of Common  Stock at the time  subject to
such option and may be exercised for all or any portion of such shares. Upon the
consummation  of the Corporate  Transaction,  all automatic  option grants under
this Article Three shall  terminate and cease to be  outstanding,  except to the
extent assumed by the successor corporation (or parent thereof).

                  B.  In   connection   with  any   Change  in  Control  of  the
Corporation,  the  exercisability  of each  automatic  option  grant at the time
outstanding under this Article Three shall automatically accelerate so that each
such option shall,  immediately  prior to the specified  effective  date for the
Change in Control,  become fully exercisable with respect to the total number of
shares of Common  Stock at the time  subject to such option and may be exercised
for all or any portion of such shares.  For purposes of this  Article  Three,  a
Change in Control shall be deemed to occur in the event:

                                  (i) any  person or  related  group of  persons
         (other than the  Corporation  or a person that  directly or  indirectly
         controls,  is  controlled  by, or is under  common  control  with,  the
         Corporation)  directly  or  indirectly  acquires  beneficial  ownership
         (within  the  meaning  of Rule  13d-3  of the 1934  Act) of  securities
         possessing  more than fifty percent (50%) of the total combined  voting
         power of the Corporation's  outstanding securities pursuant to a tender
         or exchange offer; or

                                  (ii) there is a change in the  composition  of
         the Board over a period of twenty-four (24) consecutive  months or less
         such that a majority of the Board members  ceases,  by reason of one or
         more proxy contests for the election of Board members,  to be comprised
         of  individuals  who either (A) have been  Board  members  continuously
         since  the  beginning  of such  period  or (B)  have  been  elected  or
         nominated for election as Board members  during such period by at least
         two-thirds of the Board members  described in clause (A) who were still
         in office at the time such election or  nomination  was approved by the
         Board.

                  C. Upon the occurrence of a Hostile Take-Over,  each automatic
option  grant  which  has  been  outstanding  under  this  Article  Three  shall
automatically  be  cancelled  in  return  for  a  cash   distribution  from  the
Corporation  in an amount equal to the excess of (i) the Take-Over  Price of the
shares of Common Stock at the time subject to the cancelled  option  (whether or
not the option is otherwise at the time exercisable for such shares) over

                                       18.


<PAGE>



(ii) the aggregate exercise price payable for such shares. The cash distribution
payable upon such cancellation  shall be made within five (5) days following the
consummation  of the  Hostile  Take-Over.  Stockholder  approval  of  this  1997
restatement  of  the  Plan  shall   constitute   pre-approval   of  each  option
subsequently  granted  with such an  automatic  cancellation  provision  and the
subsequent  cancellation  of that  option  in  accordance  with  the  terms  and
provisions  of  this  paragraph  III.C.  No  additional  approval  of  the  Plan
Administrator  or the Board shall be  required at the time of the actual  option
cancellation and cash distribution.

                  D. For purposes of this Article Three, Hostile Take-Over shall
have the meaning  assigned to such term in  paragraph  V.B of Article  Two.  The
Take-Over  Price per share shall be deemed to be equal to the greater of (a) the
fair market value per share on the date of cancellation,  as determined pursuant
to the  valuation  provisions  of  paragraph  I.A.3 of Article  Two,  or (b) the
highest reported price per share paid in effecting such Hostile Take-Over.

                  E. The shares of Common Stock subject to each option cancelled
in connection  with the Hostile  Take-Over shall not be available for subsequent
issuance under this Plan.

                  F. The automatic option grants  outstanding under this Article
Three shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize  or otherwise  change its capital or business  structure or to merge,
consolidate,  dissolve,  liquidate  or sell or  transfer  all or any part of its
business or assets.

                                  ARTICLE FOUR

                                  MISCELLANEOUS

        I.        AMENDMENT OF THE PLAN

                  The  Board  shall  have  complete  and  exclusive   power  and
authority  to  amend  or  modify  the  Plan in any or all  respects  whatsoever.
However,  no such amendment or  modification  shall,  without the consent of the
holders,  adversely affect rights and obligations with respect to options at the
time  outstanding  under the Plan. In addition,  certain  amendments may require
stockholder approval pursuant to applicable laws or regulations.

       II.        EFFECTIVE DATE AND TERM OF PLAN

                  A. The  Corporation's  1983 Stock  Option  Plan was  initially
adopted  by  the  Board  of  Directors  in  October  1983  and  approved  by the
Corporation's  stockholders  in November  1983.  In January  1987,  the Plan was
renamed the Komag,  Incorporated  1987 Stock Option Plan. The Board then amended
the Plan in May 1987 and such amendment was approved by the  stockholders at the
Annual Meeting held in May 1987. The Plan was subsequently  amended and restated
by the  Board  in  December  1987  and  January  1988,  respectively,  and  such
restatement  and  amendments  were  approved by the  stockholders  at the Annual
Meeting  held in June of 1988.  The Plan was  further  amended  by the  Board in
January 1991 and the amendment was approved by the stockholders in May 1991. The
January 23, 1992  restatement  of the Plan,  together with the  1,000,000  share
increase,  was approved by the Board on January 23, 1992 and became effective on
such date. The stockholders approved the January 23, 1992 restatement on May 21,
1992. On January 27, 1994,  the Board adopted an amendment  which  increased the
number  of  shares  of Common  Stock  issuable  under the Plan by an  additional
1,000,000  shares.  The increase was  approved by the  stockholders  at the 1994
Annual Meeting.

                  B. On January 24, 1995, the Board approved an amendment to the
Plan to effect the following changes to the Automatic Option Grant Program:  (i)
increase the number of shares subject to the initial automatic option grant made
to newly-elected or newly-appointed non-employee Board members from 3,500 shares
to 20,000 shares per  individual;  (ii) increase the number of shares subject to
the annual  automatic  option grant made to each re-elected  non-employee  Board
member from 3,500 shares to 5,000 shares;  and (iii) adjust the vesting schedule
in effect for each such annual  5,000-share  grant to provide  for full  vesting
upon completion of one (1) year of Board service rather than annual vesting over
a four (4)-year  period.  The  amendments to the Automatic  Option Grant Program
were approved by the stockholders at the 1995 Annual Meeting.

                  C. In January 1996 the Board approved an amendment to the Plan
to (i) eliminate the discretion of the Plan Administrator to grant options under
the  Discretionary  Option Grant  Program with an exercise  price per share less
than 100% of the fair market

                                       20.


<PAGE>



value per  share of Common  Stock on the grant  date,  (ii)  eliminate  the loan
provisions  of the Plan  pursuant to which one or more holders of options  under
the Discretionary  Option Grant Program would have otherwise had the opportunity
to finance the exercise of those options  through the delivery of  full-recourse
promissory  notes,  (iii) increase the number of shares of Common Stock reserved
for issuance  over the term of the Plan by an  additional  3,000,000  shares and
(iv) adjust the number of shares  granted to  non-employee  Board  members.  The
clause (iii) and (iv) amendments  were approved by the  stockholders at the 1996
Annual Meeting.

                  D. In March 1997 the Board  amended and  restated  the Plan to
effect the  following  revisions:  (i)  increase  the number of shares of Common
Stock reserved for issuance over the term of the Plan by an additional 2,500,000
shares,  (ii) render the  non-employee  Board members eligible to receive option
grants under the Discretionary Option Grant Program, (iii) allow unvested shares
issued under the Plan and  subsequently  repurchased  by the  Corporation at the
option  exercise  price or issue price paid per share to be  reissued  under the
Plan, (iv) remove certain  restrictions on the eligibility of non-employee Board
members to serve as Plan  Administrator  and (v)  effect a series of  additional
changes  to the  provisions  of the Plan  (including  the  stockholder  approval
requirements) in order to take advantage of the recent  amendments to Rule 16b-3
of the  Securities  Exchange  Act of 1934,  as amended,  which  exempts  certain
officer and director  transactions under the Plan from the short-swing liability
provisions of the federal  securities  laws. The 1997 restatement of the Plan is
subject to stockholder approval at the 1997 Annual Meeting.

                  E. The special sale and remittance  procedure for the exercise
of  outstanding  options  under the Plan,  which  was  approved  by the Board in
January 1991,  shall be in effect for all options  outstanding as of January 24,
1991 which  already  include such  procedure as a method of exercise and for all
options  granted after January 24, 1991. In addition,  such  procedure  shall be
available for all non-qualified options currently held by officers and directors
which  do not  otherwise  include  such  procedure  and  for  any  disqualifying
dispositions of Incentive Option shares effected after January 24, 1991.

                  F. The  provisions  of each  restatement  and amendment of the
Plan apply only to stock options and stock appreciation rights granted under the
Plan from and after the effective  date of such  restatement  or amendment.  All
stock options and stock  appreciation  rights issued and  outstanding  under the
Plan  immediately  prior to such effective date shall continue to be governed by
the terms and conditions of the Plan (and the respective  instruments evidencing
each such option or stock appreciation right) as in effect on the date each such
option or stock  appreciation right was previously  granted,  and nothing in any
such  restatement or amendment shall be deemed to affect or otherwise modify the
rights or  obligations  of the  holders of such  options  or stock  appreciation
rights with  respect to their  acquisition  of shares of Common Stock under such
options or their exercise of such stock appreciation rights.


                                       21.

                  G. Unless sooner  terminated in accordance  with paragraph III
of  Articles  Two and Three,  the Plan shall  terminate  upon the earlier of (i)
January 22,  2002 or (ii) the date on which all shares  available  for  issuance
under the Plan shall have been issued or  cancelled  pursuant to the exercise or
surrender of options granted hereunder. If the date of termination is determined
under  clause  (i) above,  then  options  outstanding  on such date shall not be
affected  by the  termination  of the Plan and shall  continue to have force and
effect in accordance  with the  provisions of the  instruments  evidencing  such
options.

                  H. Options may be granted  under this Plan to purchase  shares
of Common  Stock in excess of the number of shares then  available  for issuance
under the Plan,  provided (i) an  amendment  to increase  the maximum  number of
shares  issuable  under the Plan is  adopted by the Board  prior to the  initial
grant  of any such  option  and is  thereafter  submitted  to the  Corporation's
stockholders  for  approval  and (ii) each  option so  granted  is not to become
exercisable,  in whole or in part,  at any time prior to the  obtaining  of such
stockholder approval.

      III.        USE OF PROCEEDS

                  Any cash proceeds received by the Corporation from the sale of
shares  pursuant  to options  granted  under the Plan shall be used for  general
corporate purposes.

       IV.        TAX WITHHOLDING

                  The  Corporation's  obligation to deliver  shares or cash upon
the exercise or surrender of any option granted under the  Discretionary  Option
Grant Program shall be subject to the  satisfaction  of all applicable  federal,
state and local income and employment tax withholding requirements.

        V.        NO EMPLOYMENT/SERVICE RIGHTS

                  Neither  the  action of the  Corporation  in  establishing  or
restating the Plan,  nor any action taken by the Plan  Administrator  hereunder,
nor any  provision  of the  restated  Plan shall be construed so as to grant any
individual the right to remain in the employ or service of the  Corporation  (or
any parent or subsidiary  corporation) for any period of specific duration,  and
the Corporation (or any parent or subsidiary  corporation retaining the services
of such individual) may terminate such individual's employment or service at any
time and for any reason, with or without cause.

       VI.        REGULATORY APPROVALS

                  The  implementation  of the Plan,  the  granting of any option
hereunder,  and the issuance of stock upon the exercise or surrender of any such
option shall be subject to the  Corporation's  procurement  of all approvals and
permits required by regulatory  authorities  having  jurisdiction over the Plan,
the options granted under it and the stock issued pursuant to it.

                      Non-Statutory Stock Option Agreement





<PAGE>

                                    EXHIBIT A

                               KOMAG, INCORPORATED
                  NON-EMPLOYEE DIRECTOR STOCK OPTION AGREEMENT

                              INITIAL OPTION GRANT

RECITALS

                  A. The  Corporation  has  approved an  automatic  option grant
program under the Restated 1987 Stock Option Plan (the "Plan") pursuant to which
the non-employee  members of the Corporation's  Board of Directors (the "Board")
will  automatically  receive  periodic option grants designed to reward them for
services they have rendered to the Corporation and to encourage them to continue
in the service of the Corporation.

                  B. Optionee is a  non-employee  member of the Board,  and this
Agreement is executed pursuant to, and is intended to carry out the purposes of,
the Plan in connection with the automatic grant on this day of a stock option to
purchase  shares of the  Corporation's  common stock,  $0.01 par value  ("Common
Stock"), under the Plan.

                  C. The granted option is intended to be a non-statutory option
which does not meet the  requirements  of Section  422 of the  Internal  Revenue
Code.

                  NOW, THEREFORE, it is hereby agreed as follows:

                  1.  Grant  of  Option.  Subject  to and  upon  the  terms  and
conditions set forth in this  Agreement and in the notice of grant  accompanying
this Agreement  ("Notice of Grant"),  there is hereby  automatically  granted to
Optionee,  as of the date of grant  specified in the Notice of Grant (the "Grant
Date"),  a  stock  option  to  purchase  up to  the  number  of  shares  of  the
Corporation's  Common Stock (the "Option  Shares") as is specified in the Notice
of Grant at the price per share (the "Option Price")  specified in the Notice of
Grant  which is one  hundred  percent  (100%)  of the fair  market  value of the
Corporation's Common Stock on the grant date.

                  2. Option Term.  The automatic  option grant shall have a term
of ten (10) years measured from the automatic  grant date and shall  accordingly
expire at the close of business on the  Expiration  Date specified in the Notice
of Grant, unless sooner terminated in accordance with Paragraph 5 or 7.

                  3.  Limited  Transferability.  This option may, in  connection
with  optionee's  estate  plan,  be  assigned  in  whole or in part  during  the
optionee's lifetime to one or more members of the optionee's immediate family or
to a trust  established  exclusively  for one or more such family  members.  The
assigned portion may only be exercised by the person or


<PAGE>



persons  who  acquire a  proprietary  interest  in the  option  pursuant  to the
assignment.  The terms  applicable to the assigned  portion shall be the same as
those in effect for the option immediately prior to such assignment and shall be
set forth in such documents  issued to the assignee as the  administrator of the
Plan may deem appropriate.

                  4. Dates of Exercise. This option shall become exercisable for
the Option  Shares in a series of four (4)  successive  annual  installments  as
follows:

                                  (i) The option  shall become  exercisable  for
         twenty- five percent (25%) of the Option Shares upon the  completion of
         twelve (12) months of Board service  measured from the automatic  grant
         date.

                                  (ii) The option shall become  exercisable  for
         an additional  twenty-five  percent (25%) of the Option Shares upon the
         completion of  twenty-four  (24) months of Board service  measured from
         the automatic grant date.

                                  (iii) The option shall become  exercisable for
         an additional  twenty-five  percent (25%) of the Option Shares upon the
         completion of thirty-six (36) months of Board service measured from the
         automatic grant date.

                                  (iv) The option shall become  exercisable  for
         the final  twenty-five  percent  (25%) of the  Option  Shares  upon the
         completion of  forty-eight  (48) months of Board service  measured from
         the automatic grant date.

                           As the  option  becomes  exercisable  for one or more
installments of the Option Shares, those installments shall accumulate,  and the
option shall  remain  exercisable  for the  accumulated  installments  until the
expiration or sooner termination of the option term.

                  5.  Termination  of Board  Membership.  Should the  Optionee's
service as a Board member cease while this option remains outstanding,  then the
option term  specified  in  Paragraph 2 shall  terminate  (and this option shall
cease to remain outstanding) prior to the Expiration Date in accordance with the
following provisions:

                                  (i) Should Optionee cease to be a Board member
         for any reason other than death while  holding  this  option,  then the
         period for  exercising  this option shall be reduced to a six (6)-month
         period  commencing with the date of such cessation of Board membership,
         but in no event shall this option be  exercisable at any time after the
         Expiration  Date.  During such limited period of  exercisability,  this
         option may not be exercised in the  aggregate  for more than the number
         of Option Shares (if any) for which it is  exercisable  on the date the
         Optionee ceased service as a Board member.

                                       2.

<PAGE>



         Upon the  expiration of such six (6)-month  period or (if earlier) upon
         the  specified  Expiration  Date of the option  term,  the option shall
         terminate and cease to be exercisable.

                                  (ii) Should  Optionee  die while  serving as a
         Board member or during the six  (6)-month  period  following his or her
         cessation of Board  service,  then the personal  representative  of the
         Optionee's  estate  or the  person  or  persons  to whom the  option is
         transferred  pursuant to the Optionee's  will or in accordance with the
         laws of descent and distribution  shall have the right to exercise this
         option for any or all of the  Option  Shares for which the option is at
         the time exercisable.  Such right of exercise shall terminate, and this
         option shall accordingly  cease to be outstanding,  upon the earlier of
         (A) the expiration of the twelve  (12)-month  period  measured from the
         date of Optionee's  death or (B) the specified  Expiration  Date of the
         option term.

                  6.       Adjustment in Option Shares.

                  A.  In the  event  any  change  is made  to the  Common  Stock
issuable  under the Plan  (whether  by reason of (i)  merger,  consolidation  or
reorganization   or  (ii)   recapitalization,   stock  dividend,   stock  split,
combination of shares,  exchange of shares or other similar change affecting the
outstanding  Common Stock as a class without  receipt of  consideration),  then,
unless  such  change  results  in the  termination  of all  outstanding  options
pursuant to the  provisions  of  paragraph  III of Articles Two and Three of the
Plan, the number and class of securities  purchasable  under this option and the
Option Price  payable per share shall be  appropriately  adjusted to prevent the
dilution or enlargement of the Optionee's rights and benefits hereunder.

                  B. If this  option is assumed in  connection  with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would  have  been  issuable  to  Optionee  in  consummation  of  such  Corporate
Transaction  had the option been exercised  immediately  prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Option Price,
provided the aggregate Option Price shall remain the same.

                  7. Corporate Transaction. In the event of any of the following
stockholder-approved transactions (a "Corporate Transaction"):

                                  (i) a  merger  or  acquisition  in  which  the
         Corporation is not the surviving  entity,  except for a transaction the
         principal  purpose of which is to change the State of the Corporation's
         incorporation,

                                  (ii) the sale,  transfer or other  disposition
         of all or substantially all of the assets of the Corporation, or

                                       3.

<PAGE>




                                  (iii)   any   reverse   merger  in  which  the
         Corporation is the surviving entity,

                           this option,  to the extent  outstanding at the time,
shall automatically  accelerate so that such option shall,  immediately prior to
the  specified  effective  date  for the  Corporate  Transaction,  become  fully
exercisable  for all of the Option  Shares at the time subject to the option and
may be exercised  for any or all of those Option Shares as  fullyvested  shares.
Immediately following the consummation of the Corporate Transaction, this option
shall terminate and cease to be outstanding, except to the extent assumed by the
successor corporation (or parent thereof).

                  8.       Change In Control/Hostile Takeover.

                  A. Immediately  prior to the occurrence of a Change in Control
as defined below,  this option,  to the extent  outstanding  at the time,  shall
automatically  accelerate  and  become  immediately  exercisable  for all of the
Option  Shares at the time subject to the option and may be exercised for any or
all of those  Option  Shares as  fully-vested  shares.  The option  shall remain
exercisable for such fully-vested  shares until the earlier of (i) the specified
Expiration  Date of the  option  term  or (ii)  the  termination  of the  option
pursuant to the provisions of Paragraph 5.

                  B. Upon the  occurrence  of a  Hostile  Takeover  (as  defined
below),  this option  shall be  automatically  cancelled  in exchange for a cash
payment  from  the  Corporation  in an  amount  equal to the  excess  of (I) the
Take-Over  Price of all the Option  Shares at the time subject to the  cancelled
option over (II) the aggregate  Option Price  payable for such shares.  The cash
payment  shall be made within five (5) days  following the  consummation  of the
Hostile Take-Over.

                  C. For purposes of this Paragraph 8, the following definitions
shall be in effect:

                                  A Change in  Control  shall be deemed to occur
         in the event:

                                  (i) any  person or  related  group of  persons
         (other than the  Corporation  or a person that  directly or  indirectly
         controls,  is  controlled  by, or is under  common  control  with,  the
         Corporation)  directly  or  indirectly  acquires  beneficial  ownership
         (within the  meaning of Rule 13d-3 of the  Securities  Exchange  Act of
         1934) of  securities  possessing  more than fifty  percent (50%) of the
         total combined voting power of the Corporation's outstanding securities
         pursuant to a tender or exchange offer; or



                                       4.

<PAGE>



                                  (ii) there is a change in the  composition  of
         the Board over a period of twenty-four (24) consecutive  months or less
         such that a majority of the Board members  ceases,  by reason of one or
         more proxy contests for the election of Board members,  to be comprised
         of  individuals  who either (A) have been  Board  members  continuously
         since  the  beginning  of such  period  or (B)  have  been  elected  or
         nominated for election as Board members  during such period by at least
         two-thirds of the Board members  described in clause (A) who were still
         in office at the time such election or  nomination  was approved by the
         Board.

                                  A Hostile  Take-Over  shall be deemed to occur
         in the event any person or related  group of  persons  (other  than the
         Corporation  or a person  that  directly  or  indirectly  controls,  is
         controlled  by,  or is under  common  control  with,  the  Corporation)
         directly  or  indirectly  acquires  beneficial  ownership  (within  the
         meaning  of Rule  13d-3  of the  Securities  Exchange  Act of  1934) of
         securities  possessing  more  than  fifty  percent  (50%) of the  total
         combined  voting  power  of the  Corporation's  outstanding  securities
         pursuant  to a tender  or  exchange  offer  which  the  Board  does not
         recommend the Corporation's stockholders to accept.

                                  The Take-Over  Price per share shall be deemed
         to be equal to the  greater of (a) the Fair  Market  Value per share on
         the date of the option  cancellation or (b) the highest  reported price
         per share paid in effecting such Hostile Take-Over.

                  9.       Manner of Exercising Option.

                  A. In order to exercise this option for all or any part of the
Option Shares,  Optionee (or in the case of exercise after Optionee's death, the
Optionee's  executor,  administrator,  heir or legatee, as the case may be) must
take the following actions:

                                  (i) Either provide the Stock  Administrator of
         the  Corporation  (or  his/her  designee)  with  written  notice of the
         exercise in which there is  specified  the number of Option  Shares for
         which the option is being  exercised or initiate  the exercise  through
         the    interactive     response    system     established     with    a
         Corporation-designated brokerage firm.

                                  (ii) Pay the  aggregate  Option  Price for the
         purchased shares in one or more of the following alternative forms:

                                  1. full  payment in cash or check drawn to the
         Corporation's order; or


                                       5.

<PAGE>



                                  2. full payment in shares of Common Stock held
         by the Optionee for the requisite period necessary to avoid a charge to
         the Corporation's  reported earnings for financial  reporting  purposes
         and valued at Fair Market Value on the Exercise Date; or

                                  3.  full  payment  through  a  combination  of
         shares of Common Stock held by the Optionee  for the  requisite  period
         necessary to avoid a charge to the Corporation's  reported earnings for
         financial  reporting  purposes  and valued at Fair Market  Value on the
         Exercise  Date and cash or check,  equal to the aggregate of the Option
         Price; or

                                  4. payment  effected  through a  broker-dealer
         sale and  remittance  procedure  pursuant to which the  Optionee  shall
         provide  irrevocable   instructions  to  (I)  a  Corporation-designated
         brokerage firm to effect the immediate sale of the purchased shares and
         remit to the  Corporation,  out of the sale  proceeds  available on the
         settlement  date, an amount equal to the aggregate option price payable
         for the purchased  shares plus all applicable  Federal and State income
         and  employment  taxes  required to be withheld by the  Corporation  by
         reason  of such  purchase  and  (II) the  Corporation  to  deliver  the
         certificates for the purchased shares directly to such brokerage firm.

                                  (iii) Furnish to the  Corporation  appropriate
         documentation  that the person or persons  exercising  the  option,  if
         other than Optionee, have the right to exercise this option.

                  B. For  purposes  of  subparagraph  A above  and for all other
valuation  purposes  under this  Agreement,  the Fair Market  Value per share of
Common Stock on any relevant date shall be  determined  in  accordance  with the
following provisions:

                                  (i) If the Common  Stock is at the time traded
         on the Nasdaq National Market,  then the Fair Market Value shall be the
         closing  selling  price  per  share  of  Common  Stock  on the  date in
         question,  as such price is reported  by the  National  Association  of
         Securities  Dealers  on the  Nasdaq  National  Market or any  successor
         system.  If there is no closing  selling  price for the Common Stock on
         the  date in  question,  as such  price  is  reported  by the  National
         Association of Securities  Dealers on the Nasdaq National Market or any
         successor  system.  If there is no closing selling price for the Common
         Stock on the date in question,  then the Fair Market Value shall be the

                                  (ii) If the Common Stock is at the time listed
         on either the New York Stock Exchange or the American  Stock  Exchange,
         then the Fair Market Value shall be the closing selling price per share
         of Common Stock on the date in question on such exchange, as such price
         is officially  quoted in the  composite  tape of  transactions  on that
         exchange.  If there is no closing selling price for the Common Stock on
         the date in  question,  then the Fair Market Value shall be the closing
         selling  price on the last  preceding  date for  which  such  quotation
         exists.

                  C. The Exercise Date shall be the first date on which there is
compliance  with all the terms and  conditions  of  subparagraphs  A and B above
applicable to such exercise.

                  D.  As  soon  as  practical   after  the  Exercise  Date,  the
Corporation  shall issue to or on behalf of the Optionee (or any other person or
persons  exercising this option) a certificate or certificates  representing the
Option Shares purchased and paid for in accordance herewith.

                  E. In no event may this option be exercised for any fractional
share.

                  10.  Stockholder  Rights.  The holder of this option shall not
have any of the rights of a stockholder  with respect to the Option Shares until
such individual shall have exercised this option,  paid the Option Price for the
purchased  shares and been  issued one or more  certificates  for the  purchased
shares.

                  11. No Impairment of Rights.  This Agreement  shall not in any
way affect the right of the  Corporation  to adjust,  reclassify,  reorganize or
otherwise  make  changes  in its  capital  or  business  structure  or to merge,
consolidate,  dissolve,  liquidate  or sell or  transfer  all or any part of its
business  or  assets.  Nor  shall  this  Agreement  in any way be  construed  or
interpreted  so as to affect  adversely  or otherwise  impair the  Corporation's
right to remove the Optionee from the Board at any time in  accordance  with the
provisions of applicable law.

                  12. Compliance with Laws and Regulations. The exercise of this
option and the issuance of the Option Shares upon such exercise shall be subject
to  compliance  by  the   Corporation  and  the  Optionee  with  all  applicable
requirements of law relating thereto and with all applicable  regulations of any
stock exchange (or the Nasdaq National Market, if applicable) on which shares of
the Corporation's Common Stock are at the time listed for trading.

                  14.  Discharge of Liability.  The inability of the Corporation
to obtain  approval  from any  regulatory  body having  authority  deemed by the
Corporation to be necessary to the lawful  issuance and sale of any Common Stock
pursuant to this option shall  relieve the  Corporation  of any  liability  with
respect  to the  non-issuance  or sale of the  Common  Stock  as to  which  such
approval shall not have been obtained.  However,  the Corporation  shall use its
best efforts to obtain all such applicable approvals.

                               KOMAG, INCORPORATED
                              MANAGEMENT BONUS PLAN

                    AS AMENDED AND RESTATED JANUARY 22, 1997


        I.        PURPOSES OF THE PLAN

                  1.01 The Komag, Incorporated ("Company") Management Bonus Plan
("Plan") is  established  to promote the interests of the Company by creating an
incentive  program to (i)  attract  and  retain  employees  who will  strive for
excellence, and (ii) motivate those individuals to set and achieve above-average
objectives  by providing  them with rewards for  contributions  to the operating
profits and earning power of the Company.

       II.        ADMINISTRATION OF THE PLAN

                  2.01 The Plan was adopted by the Company's  Board of Directors
(the  "Board") and  approved at the  Company's  stockholders  at the 1996 Annual
Stockholders  Meeting.  The  Plan  shall  be  administered  by the  Compensation
Committee  ("Committee") of the Board. The members of the Committee shall at all
times satisfy the requirements  established for outside directors under Internal
Revenue Code Section 162(m) and the applicable Treasury Regulations.

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

                  2.03  Within 90 days after the start of each of the  Company's
fiscal years, the Committee will determine which of the Company's  subsidiaries,
if any, will participate in the Plan for such fiscal year.

      III.        DETERMINATION OF PARTICIPANTS

                  3.01 An  individual  shall be eligible to  participate  in the
Plan if employed by the Company or any of its  participating  subsidiaries for a
period  of not less  than six (6)  consecutive  months  at the time the bonus is
earned under Article IV, is in job grade E06 or above,  and remains eligible for
a bonus award under the terms of Section 4.01 or 4.03. An individual who is on a
leave of absence or whose employment terminates and is then re-hired in the same
fiscal year shall remain eligible, but his or her bonus award shall be adjusted,
as provided in Article IV below.




<PAGE>




                  3.02              For purposes of the Plan:

                                  A.  Except as set forth in  Section  3.01,  an
individual  shall  be  considered  an  employee  for so long as such  individual
remains employed by the Company or one or more subsidiary corporations.

                                  B. Each  corporation  (other than the Company)
in an  unbroken  chain  of  corporations  beginning  with the  Company  shall be
considered  to be a subsidiary of the Company,  provided  each such  corporation
(other than the last  corporation  in the unbroken  chain) owns,  at the time of
determination,  stock  possessing  more than fifty percent of the total combined
voting  power of all classes of stock in one of the other  corporations  in such
chain.

       IV.        BONUS AWARDS

                  4.01 No  eligible  employee  shall earn any portion of a bonus
award made hereunder for any fiscal year until the last day of that fiscal year,
and then only if there has been an allocation of a portion of the bonus pool for
such fiscal year to that employee in accordance with the procedures set forth in
Section 4.03. If an eligible employee receives no allocation under Section 4.03,
then that employee  shall not earn,  and shall not otherwise be entitled to, any
bonus  under the Plan for that  fiscal  year.  In no event  shall  any  employee
receive an  allocation  under  Section  4.03 for a fiscal year if that  employee
ceases to be employed by either the Company or one or more of its  participating
subsidiary  corporations for any reason,  other than retirement after the age of
65,  permanent  disability or death, on or before the date the allocation of the
bonus pool for that fiscal year is made under section 4.03.  Notwithstanding the
foregoing,  if an  employee  is  employed  during part of the fiscal year by the
Company or any other participating subsidiary in the Plan and for all or part of
the remainder of that fiscal year by a subsidiary  that is not covered under the
Plan, then any bonus to which that employee would otherwise be entitled for such
fiscal year had he/she  continued in the employ of the Company or  participating
subsidiary  shall be reduced by the  proportion of such fiscal year during which
the employee was employed by the non-participating subsidiary.

                  4.02 The Committee shall calculate the aggregate bonus pool to
be paid under the Plan for each fiscal year.  The specific  percentage in effect
for the fiscal year shall be determined in accordance  with the Company's  level
of success in achieving the budgeted  operating income specified for that fiscal
year in the  annual  Financial  Plan  ("Budgeted  Operating  Income")  which  is
approved by the Board and ratified for purposes of the Plan by the Committee not
later than 90 days after the start of the fiscal year, as follows:

                                  X = The percentage of the Operating  Income of
         the Company and its subsidiaries covered by the Plan that comprises the
         bonus pool.

                                       2.

<PAGE>




                                  Y = Actual  Operating  Income  for the  fiscal
         year divided by Budgeted Operating Income.

                                  If Y is 0.6667 or greater, then X = 9(Y)-4

                                  If Y is less than 0.6667, then X = 3Y

                                  No  amount  shall  be paid if Y is zero (0) or
         less.

                                  The  maximum  value for X shall be  limited to
seven  percent  (7%),  and in no event shall X exceed eight  percent (8%) of the
Company's Consolidated Operating Income.

                                  For   purposes  of  this  Section  4.02  bonus
formula, the following definitions shall be in effect:

                                  "Operating   Income"   means   the   Company's
         operating  income for the fiscal year  attributable  to the Company and
         the participating subsidiaries for that year.

                                  "Consolidated   Operating  Income"  means  the
         Company's   consolidated   operating   income  for  the   fiscal   year
         attributable to the Company and all its subsidiaries.

                                  In each case,  the  calculations  of Operating
Income and  Consolidated  Operating Income shall be in accordance with generally
accepted  accounting  principles,  adjusted  to exclude the  following:  (i) any
amounts accrued by the Company or its subsidiaries  pursuant to Management Bonus
Plans or Cash Profit Sharing Plans and related  employer  payroll taxes for such
fiscal  year,  (ii) any  Discretionary  or  Matching  Contributions  made to the
Savings  and  Deferred  Profit-Sharing  Plan  or to the  Non-Qualified  Deferred
Compensation Plan for such fiscal year, (iii) all items of gain, loss or expense
for such  fiscal year  determined  to be  extraordinary  or unusual in nature or
infrequent in occurrence, or related to the disposal of a segment of a business,
all as determined in accordance with the standards established by Opinion No. 30
of the  Accounting  Principles  Board  (APB No.  30),  (iv) any  adjustments  to
earnings,  gain,  loss  or  expense  attributable  to  a  change  in  accounting
principles or standards,  (v) all items of gain, loss or expense for such fiscal
year related to restructuring  charges of subsidiaries  whose operations are not
included in Operating  Income for such fiscal year, (vi) all items of gain, loss
or expense for such fiscal year related to discontinued  operations which do not
qualify  as a segment of a  business  as defined  under APB No. 30 and (vii) any
profit or loss attributable to the business operations of any entity acquired by
the Company during such fiscal year.  Operating Income shall not be adjusted for
a minority  interest  holder's  share of a consolidated  subsidiary's  operating
income or loss.


                                       3.


<PAGE>




                  4.03  The  aggregate  bonus  pool  calculated  in  the  manner
provided in Section  4.02 shall be  allocated  among the  eligible  employees in
accordance with this Section 4.03.

                                  A. Each of the  Company's  executive  officers
(salary  grades E11 and above) will be assigned an index which is the product of
his or her base  salary,  measured  as of the close of the fiscal year for which
the  bonus  allocation  is made,  times a  multiplier.  The  multiplier  for the
President and Chief Executive  Officer and the Chairman of the Board will be two
(2). For each Senior Vice President (E12), the multiplier will be one-point-five
(1.5), and for every other Vice President (E11) the multiplier will be one (1).

                                  B. Bonuses  will be awarded to each  executive
officer  by  multiplying  the  aggregate  bonus  pool for the  fiscal  year by a
fraction the numerator of which will be the individual  officer's  index and the
denominator of which will be the sum of the indices for all executive officers.

                                  C. The Committee may, in its sole judgment and
discretion, reduce the bonus allocation to any or all of the executive officers.

                                  D.  The  sum  of  all   amounts  not  paid  to
executive  officers  pursuant to Section  4.03C shall serve as a separate  bonus
pool for the  fiscal  year which may be  allocated  in whole or in part to other
officers  and  exempt  employees  grade  E06 and  above.  One or more  executive
officers  of the  Company  may  make  recommendations  to the  Chairman  and the
President with respect to the  non-executive-officer  employees who should share
in such bonus pool and the  portion  of such pool to be  allocated  to each such
individual. The Chairman and the President shall review such recommendations and
shall, in their  discretion,  submit one or more of such  recommendations  (with
such adjustments as they deem  appropriate) to the Committee for  consideration.
On the basis of such  recommendations,  the  Committee  shall select one or more
such  non-executive-officer  employees to share in such bonus pool and determine
the  amount  of such  pool to be  allocated  to each  selected  individual.  The
determinations of the Committee shall be final.

                                  E. The bonus award made under this Plan to any
participant for any fiscal year shall not exceed $5 million.

                  4.04  Following   completion  of  the  bonus  calculation  and
allocation  referenced  above,  the  Committee  shall  issue  a  written  report
containing the final calculation and allocation.

        V.        PAYMENT OF BONUS AWARDS

                  5.01 The  individual  bonus award  allocated to each  employee
pursuant to Section 4.03 shall be paid to such employee  within thirty (30) days
after  completion of the annual audit of the Company's  financial  statements by
its independent auditors.

                                       4.

       VI.        GENERAL PROVISIONS

                  6.01 The Plan shall become effective when adopted by the Board
and the  Company's  stockholders.  The Board may at any time  amend,  suspend or
terminate the Plan,  provided such action is effected by written  resolution and
does  not  adversely  affect  rights  and  interests  of  Plan  participants  to
individual  bonuses  allocated to them prior to such  amendment,  suspension  or
termination.  All  material  amendments  to the Plan shall  require  stockholder
approval.

                  6.02 On January 22,  1997,  the Board  adopted an amendment to
the Plan that changed the bonus  formula  under  Section 4.02  effective for all
fiscal years  following the 1996 fiscal year ended  December 27, 1996 (the "1997
Amendment").  The 1997 Amendment is subject to stockholder  approval at the 1997
Annual Meeting. If the stockholders do not approve the 1997 Amendment,  then the
bonus  formula  in  effect  under  Section  4.02  immediately  prior to the 1997
Amendment shall  automatically be reinstated,  and the bonus pool shall continue
to be calculated in accordance with the reinstated formula.

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

                  6.04 No Plan  participant  shall  have the right to  alienate,
pledge or encumber  his/her  interest in this Plan,  and such interest shall not
(to the  extent  permitted  by law) be  subject  in any way to the claims of the
employee's creditors or to attachment, execution or other process of law.

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

                  6.06  This is the  full and  complete  agreement  between  the
eligible employees and the Company on the terms described herein.


                                       5.
