                               KOMAG, INCORPORATED
                             1704 Automation Parkway

                                 PROXY STATEMENT
                     FOR THE ANNUAL MEETING OF STOCKHOLDERS
                             TO BE HELD MAY 25, 1999



                                     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 25,  1999.  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 29,  1999 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 May 3, 1999.


Voting

         Your vote is  important.  Because many  stockholders  cannot attend the
meeting,  it is  necessary  that a large  number be  represented  by  proxy.  As
described in more detail below,  if you are a stockholder of record you may vote
four ways:  (1) by attending  the  meeting,  (2) by using the  toll-free  number
listed on the proxy card, (3) by voting on the Internet at the address listed on
the proxy card, or (4) by marking,  signing,  dating,  and mailing your proxy in
the envelope provided.

         On March 29, 1999, the record date for  determination  of  stockholders
entitled to vote at the Annual Meeting,  there were 53,920,660  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 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.

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  Plans.  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 to purchase 30,000 shares
of  Common  Stock.  On the  date  of  each  Annual  Stockholders  Meeting,  each
individual  who is  re-elected  as a  non-employee  Board member will receive an
option to purchase 12,000 shares of Common Stock assuming  stockholder  approval
of Item number 4, 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  non-employee  director  re-elected  at the  1998  Annual  Meeting
(Messrs.  Barrett, Eyre, Federman, Neil, Palevsky, Sun and Takebayashi) received
at that  time an option to  purchase  7,500  shares  with an  exercise  price of
$10.625 per share. Each option will become exercisable for all the option shares
upon the  optionee's  completion of one year of  non-employee  director  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 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  increase  the number of shares  available  for  issuance  by
2,550,000 shares of Common Stock. The Board of Directors believes that the share
increase is necessary to assure 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 February 4, 1999,
the Board of Directors  adopted the  amendment to the Purchase  Plan to increase
the number of shares available for issuance by 2,550,000 which is the subject of
this Item No. 2.


         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.  A copy of the Plan is  attached  hereto as
Exhibit A.


Administration


         The  Purchase  Plan is  administered  by the Primary  Stock Option Plan
Committee,  which consists of at least two non-employee  Board members appointed
by the Board. 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 7,400,000 shares,
assuming  stockholder  approval  of this Item No. 2. 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.

         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 right.  Such adjustments will prevent any dilution or
enlargement of participant rights under the Purchase Plan.


                                       8

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 Material Technology,  Incorporated, Komag Asia-Pacific,  Incorporated, and
Komag U.S.A. (Malaysia) Sdn. are participating corporate affiliates.


         As of March 29, 1999,  4,115,073 shares of Common Stock had been issued
under the Purchase Plan, and 3,284,927 shares were available for future issuance
(assuming  stockholder  approval  of this Item No.  2).  As of March  29,  1999,
approximately  3,993 employees  (including 13 current  executive  officers) were
eligible to participate in the Purchase Plan.


Purchase Periods


         The  Purchase  Plan was  amended  in 1998 from a series of  overlapping
quarterly  or  semi-annual  purchase  periods  over a  duration  not  to  exceed
twenty-four  (24) months,  to a series of  successive  quarterly or  semi-annual
purchase periods not to exceed six (6) 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,  up to four (4)  separate  purchase  periods  may  commence in each
fiscal year during which the Purchase Plan remains in existence.


         Participants  are granted a separate  purchase  right for each purchase
period in which they participate. The purchase right is granted on the first day
of the purchase period and is  automatically  exercised on the last date of each
successive  three (3)-month or six (6)-month  period within that purchase period
("Purchase  Date"). No employee may participate in more than one purchase period
at a time.


Purchase Price


         The purchase  price of the Common Stock  acquired on each Purchase Date
is 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 per share
determined on such basis was $5.3125 on March 29, 1999.

Purchase Rights and Stock Purchases


         Each participant may authorize periodic payroll deductions of up to 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
accumulated  payroll deductions of each participant is automatically  applied to
the purchase of whole shares of Common Stock at the purchase price in effect for
that Purchase Date. 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.  In
addition,  no  executive  officer of the Company may  purchase  more than 50,000
shares in the aggregate over the term of the Purchase Plan.



                                       9
<PAGE>

Termination of Purchase Rights


         The  purchase  right  of  a  participant   terminates   upon  (i)  such
individual's  termination of employment or (ii) his or her voluntary  withdrawal
from the Purchase Plan. Any payroll  deductions  that the  participant  may have
made with respect to the terminated purchase right is refunded.  However, should
the  participant's   employment  terminate  by  reason  of  death  or  permanent
disability,  then that  participant (or the legal  representative  of his or her
estate)  may,  in lieu of such  refund,  elect to have the  accumulated  payroll
deductions applied to the purchase of Common Stock on the next Purchase Date.

Stockholder Rights

         No participant  has any  stockholder  rights with respect to the shares
covered by his or her purchase right 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 are assignable or  transferable  by the participant
except by will or by laws of  inheritance.  An  outstanding  purchase right may,
during the participant's lifetime, be exercisable only by that 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 at a price
per share equal to eighty-five percent of the lower of (i) the fair market value
per share of Common Stock on the start date of the purchase period in which that
transaction  occurs  or (ii)  the fair  market  value  per  share at the time of
purchase.

Amendment and Termination

         The Purchase Plan will  terminate  upon the earlier of (i) December 31,
2001 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.  However,  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.

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.

         If the participant sells or otherwise  disposes of the purchased shares
within two (2) years after the start date of 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

                                       11
<PAGE>

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  provided  that  prior  to the  beginning  of each
offering period the Company has an authorized  share reserve equal to or greater
than the  number of shares  issued  during the  offering  period.  However,  the
Company must disclose, in notes 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 1999
Annual  Meeting for approval of the amendment to the Purchase Plan. The Board of
Directors believes that the amendment to the Purchase Plan is 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 beyond
the currently authorized 4,850,000 shares.

                                  ITEM NO. 3 --
                                    FINANCING


         The Company is seeking to renew authorization from stockholders to sell
and issue up to $250 million of Common Stock in equity or equity-linked  private
transactions from time to time until October 1, 2000 at a price below book value
but at or above  the  then  current  market  value as  defined  by the  National
Association  of Securities  Dealers,  Inc. (the "NASD") of the Common Stock (the
"Financing Proposal").


Background

         The  Company  expects  to  enter  into  a  Restructuring  Agreement  to
restructure its credit facilities.  Under the proposed terms of the restructured
credit  facilities  the Company  would be  required  to repay  $15.0  million of
principal  during 1999 and another $15.0  million of principal  during the first
nine months of 2000. Additional principal payments would be due from portions of
new capital  raised,  asset sales,  and internal cash flow beyond agreed levels.
The amended loans would remain unsecured and would be due and payable in full on
October 7, 2000. The Company would have no additional credit available under the
loan  restructure  agreement.  The  Company  believes  that it will  require new
funding  prior  to the  October  2000  maturity  of its  existing  bank  debt to
facilitate  full  repayment of these  loans.  If the Company is unable to obtain
adequate new funding,  the Company will be required to further  restructure  its
bank credit facilities, and may be required to further reduce its operations and
capital  spending  which could have a material  adverse  effect on the Company's
results of operations.

         In July 1998,  the Company  solicited and received  authorization  from
stockholders  to  engage  in  transactions  identical  to  those  that  would be
authorized  by the  Financing  Proposal  in amounts of up to $350  million.  The
authority  granted by the July 1998  stockholder  resolution  was limited to one
year.  However,  because of  unfavorable  market  conditions  and other factors,
management elected not to engage in any transactions authorized by the July 1998
stockholder resolution and such authority will expire in late July. Accordingly,
the Company  seeks to renew the authority  granted by the July 1998  stockholder
resolution  for an  additional  period of time but with the maximum  transaction
amount reduced to $250 million.


Reasons For the Financing Proposal

         Under  the  Delaware   General   Corporation   Law  and  the  Company's
Certificate  of  Incorporation  and Bylaws,  no action or  authorization  by the
Company's stockholders is necessary for the Financing Proposal. However, because
the Common Stock is quoted on The Nasdaq Stock Market, the Company is subject to
the rules of the NASD. NASD Rule 4460(i) generally requires stockholder approval
for the  issuance  by a company  of shares of its  common  stock (or  securities
convertible  into or  exercisable  for common stock) equal to 20% or more of the
voting  power  of all  shares  of the  company  if  such  shares  are  sold in a
transaction  other than a public offering at a price (or with a conversion price
of) less than the greater of book value or market value of such company's common
stock.  Approval of the  Financing  Proposal  would not limit the  Company  from
taking any action for which stockholder approval is not otherwise required.

         If the Financing  Proposal is approved at the Annual Meeting and if the
Company  issues  securities  in a  transaction  subject to  approval  under Rule
4460(i),  then the Company will mail to stockholders  certain  information about
the transaction prior to issuing the securities.

         The market price of the Common Stock has been highly volatile in recent
periods.  If the  Financing  Proposal  is approved  at the Annual  Meeting,  the
Company will be authorized to issue up to $250 million of Common Stock in equity
or equity-linked private transactions from time to time until October 1, 2000 at
a price below book 


                                       13
<PAGE>

value but at or above the then  current  market  value of the Common  Stock.  At
March 29, 1999, the closing price of the Common Stock on The Nasdaq Stock Market
was $5.3125 and the book value per share of the Common  Stock on January 3, 1999
was $6.01.

         If stockholders  approve the Financing  Proposal at the Annual Meeting,
no further authorization by stockholders for the issuance of securities pursuant
to this  authorization  will be  obtained.  The  terms of the  securities  to be
authorized,  including  dividend or interest rates,  conversion  prices,  voting
rights, redemption prices, maturity dates and similar matters will be determined
by the Board of Directors.


Risk Factors

         IN ADDITION TO THE OTHER INFORMATION SET FORTH IN THIS PROXY STATEMENT,
STOCKHOLDERS  SHOULD CAREFULLY  CONSIDER THE FOLLOWING  FACTORS BEFORE ACTING ON
THE FINANCING PROPOSAL.


Dilution to Existing Stockholders; Impact on Market Value of Common Stock

         The  sale  of a  significant  amount  of  Common  Stock  or  securities
convertible  into Common  Stock could cause  substantial  dilution to the voting
power,  earnings per share and interests of current  stockholders.  In addition,
the sale of a significant number of securities convertible into shares of Common
Stock could cause a decline in the market value of the Common Stock.


Consequences If the Financing Proposal Is Not Approved

         If the Financing Proposal is not approved by the Company's stockholders
at the Annual Meeting,  the consequences could have a material adverse effect on
the Company's  business,  results of operations  and  financial  condition.  The
Company is considering  sources of funding,  including  equity or  equity-linked
financings that are dependent,  in part, on approval of the Financing  Proposal.
As discussed  above, the Company believes that it will require new funding prior
to the October 1, 2000  maturity of its existing  bank debt to  facilitate  full
repayment  of these  loans.  If the  Company  is unable to obtain  adequate  new
funding,  the Company  will be required to further  restructure  its bank credit
facilities,  and may be required to further  reduce its  operations  and capital
spending which could have a material adverse effect on the Company's  results of
operations.


         THE BOARD OF  DIRECTORS  RECOMMENDS  THAT  STOCKHOLDERS  VOTE "FOR" THE
FINANCING PROPOSAL.  ABSTENTIONS AND BROKER NON-VOTES WILL HAVE NO EFFECT ON THE
OUTCOME OF THE FINANCING  PROPOSAL.  EXECUTED BUT UNMARKED PROXIES WILL BE VOTED
"FOR" THE FINANCING PROPOSAL.

                   ITEM NO. 4 -- APPROVAL OF AMENDMENTS TO THE
                         RESTATED 1987 STOCK OPTION PLAN

Introduction

         The  stockholders  are  being  asked to  approve  an  amendment  to the
Company's  Restated  1987 Stock Option Plan (the "Option  Plan") to increase the
number  of stock  options  granted  to  non-employee  Board  members  under  the
Automatic  Option  Grant  Program from 7,500 to 12,000 upon  re-election  to the
Board each year.  The Board of  Directors  approved  the  amendment on April 15,
1999,  subject to stockholder  approval at the Annual Meeting.  Accordingly,  if
such stockholder  approval is obtained,  each of the six (6) non-employee  Board
members re-elected at the 1999 Annual Meeting will receive an option to purchase
12,000  shares of Common  Stock with an exercise  price equal to the fair market
value of the Company's Common Stock on that date.

         The Automatic  Option Grant  Program  aligns the interests of the Board
members directly with those of stockholders.  Non-employee  directors contribute
significantly  to the  well-being  of the  Company.  Based on market  data,  the
previously  authorized 7,500 shares approximates the median of peer group annual
grants to  non-employee  directors.  The proposed  share increase is intended to
enable the Company to attract and retain non-employee directors of above average
capabilities.

         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 is attached hereto as Exhibit B.


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 29, 1999, approximately 3,993 employees (including thirteen
(13) executive officers), and seven (7) non-employee Board members were eligible
to  participate  in the  Discretionary  Option  Grant  Program.  The  seven  (7)
non-employee  Board members were also eligible to  participate  in the Automatic
Option Grant Program.


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.


                                       15

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.  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  29,1999,  5,755,435  shares  were  subject to  outstanding
option grants under the Option Plan,  3,714,569  shares  remained  available for
future grant and 8,669,996 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  70% 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.

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 sales price per share on the day prior
to the date in question, as such price is reported on the Nasdaq National Market
or any successor system. If there is no closing sales price for the Common Stock
on the day prior to the date in  question,  then the fair market  value shall be
the closing  sales  price on the last  preceding  date for which such  quotation
exists. On March 29, 1999, the closing sales price per share was $5.3125.

                         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 12,000 shares of Common Stock,  assuming stockholder approval of this
Item number 4, 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.

         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. 4 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.

                    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.

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 


                                       18
<PAGE>

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.

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 under the Restated 1987 Stock Option Plan during the period from
December 29, 1997 through March 29, 1999,  excluding options regranted under the
July  1998  Option   Cancellation  and  Regrant  Program  (see  "Report  of  the
Compensation  and Primary Stock Option  Committees on Executive  Compensation");
(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 1,859,299 new option shares granted
to executive officers during the period from December 29, 1997 through March 29,
1999: (i) 1,200,505 shares will become exercisable per the schedule noted above;
(ii) 217,703 shares granted to new and promoted officers will vest incrementally
over the next  four (4) years of their  continued  service;  and  (iii)  441,091
special  retention  grant  shares will become  exercisable  at twelve (12) month
intervals  over a three to four year  period.  Over 70% 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.  Eyre,  Federman,  Neil,  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  12,000  shares,
assuming  stockholder approval of this Item number 4, with an exercise price per
share  equal to the fair  market  value 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:

         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.



                                       20
<PAGE>

         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 1999 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,  the  re-elected  non-employee  Board members will not
receive an option to purchase 12,000 shares under the Automatic Grant Program as
of the  Annual  Meeting  date,  but will  receive  an  option  to  purchase  the
previously authorized 7,500 shares.

                                  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
January 2, 2000. 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 have  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.


EXECUTIVE COMPENSATION AND RELATED INFORMATION

         In compliance with the Securities and Exchange Commission's regulations
on disclosure of Executive  Compensation,  this section  presents the Reports of
the Compensation  Committee and of the Primary Stock Option  Committee,  a Stock
Performance  Graph  comparing  Company  stockholder  return  relative to a broad
market  index and a peer group  index,  and Summary and  Companion  Compensation
Tables  presenting  a  detailed   representation  of  the  Company's   executive
compensation practices.

         REPORT OF THE COMPENSATION AND PRIMARY STOCK OPTION COMMITTEES
                            ON EXECUTIVE COMPENSATION

         The Compensation 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 further  qualify as outside  directors  under
Section  162(m) of the Internal  Revenue  Code.  The  Compensation  Committee is
accountable  for  the  approval  of  cash  compensation   programs  that  fairly
compensate  key  executives  and  employees  and that  relate  the pay levels of
officers to the performance of the Company. The Primary Stock Option Committee's
members,   Craig  R.  Barrett,  Irwin  Federman  and  Max  Palevsky  qualify  as
disinterested persons for purposes of Rule 16b-3 adopted under the 1934 Act. The
Primary  Stock Option  Committee is  responsible  for all stock option grants to
executive officers.



                                       22
<PAGE>

Objectives of the Company's Executive Compensation Plan

         The Company's  executive  compensation is based on the premise that the
executive  officers are  responsible  for achievement of the Company's goals and
objectives  and  are  rewarded  when  achievement  of  these  goals  results  in
successful financial performance.  The Committee intends to control fixed salary
costs, to provide a high degree of leverage in officers' pay based on the actual
performance  of the  Company,  to  allow  flexibility  to  respond  to  specific
individual issues such as retention, and to balance cost to stockholders against
providing  appropriate  incentives for value  creation.  To structure the actual
annual  compensation  plans,  the  Compensation  Committee  relies  on  research
performed by an independent  compensation  consulting  firm, and advice from the
Company's human resources department.  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 necessarily
industry  specific,  no attempt is made to correlate the list of peer  companies
with the  companies  in  Nasdaq  Computer  Manufacturers  Index,  the  Company's
Industry index in the "Stock Performance Graph."

         The total  compensation  plan developed for each officer  includes base
salary,  incentive bonus and stock options in addition to  participation  in the
Company's  Cash and Deferred  Profit  Sharing and Employee  Stock Purchase plans
subject to the same eligibility criteria applicable to all employees.  Executive
officers  are also  eligible  to defer  salary  under the  Company's  401(k) and
Non-qualified Deferred Compensation Plans. Average base salary is targeted at or
below the 50th percentile of base salaries for executives with similar positions
among the peer companies.  The  Compensation  Committee  considers this level of
base salary  sufficient,  in the context of the total compensation  package,  to
attract and retain  executives of the caliber  required to manage a company that
employs  leading edge  technology in a fiercely  competitive,  rapidly  changing
industry, while controlling this fixed component of compensation in the event of
poor business  conditions or company  performance.  On an individual  basis, the
base salaries of the Company's executive officers range from the 30th percentile
to the 75th  percentile.  Variation from the targeted range is due to individual
qualifications,  including performance, specific technical knowledge, experience
and/or total targeted cash compensation as judged by the Compensation Committee.

         To complement base salary, the Compensation  Committee  administers the
Management Bonus Plan (the "Bonus Plan"). This Bonus Plan is designed to provide
substantial rewards for exceeding financial performance targets and little or no
payout when the Company performs poorly. Specifically, the Bonus Plan provides a
pool of funds  available for bonus  payments  based on the  Company's  operating
income as  compared  to the Annual  Operating  Plan as  approved by the Board of
Directors in the first quarter of each fiscal year. The maximum pool is equal to
7% of operating  income when actual operating income is greater than or equal to
122% of the Annual  Operating Plan. This percentage  declines  linearly to 2% of
operating  income at a level of 66.67% of the  Annual  Operating  Plan and to 0%
when  there is no  operating  income  or an  operating  loss.  The  Compensation
Committee  allocates  this  pool  to  the  executives,  up to  each  executive's
pre-established  maximum,  and to other  non-executive  employees,  based on its
judgment of each  individual's  contributions  to the  Company's  financial  and
operating performance. Since the Company sustained an operating loss in 1998, no
payments were accrued or paid under the Bonus Plan for the fiscal year.

         The Compensation Committee also administers the Company's Discretionary
Bonus Plan (the  "Discretionary  Plan").  The Discretionary  Plan is designed to
allow  the  Compensation  Committee  the  flexibility  to  grant a  bonus  to an
executive if an executive  has achieved a  substantial  objective  during a time
when the Bonus Plan cannot provide a payout or if there is a specific  retention
issue related to the  executive's  level of income.  No payments were accrued or
made under this plan for the 1998 fiscal year.


                                       23
<PAGE>


         At the end of the second  quarter of 1998, it became  apparent that the
Company  had excess  capacity  and more  employees  than could be  supported  by
expected sales. Accordingly,  the Company restructured its operations,  recorded
an  impairment  charge and  reduced its  workforce.  In  conjunction  with these
restructuring  activities  and a  similar  action  taken at the end of the third
quarter of 1997,  the  Company  paid  approximately  $1.1  million to six former
officers,  including  $583,000  to  two  of the  individuals  in  the  following
compensation  table,  for severance and related  compensation.  Certain of these
former officers are contracted to perform consulting services during 1999.

         In addition to cash compensation the Company's  executive  compensation
plan  includes  stock  options that are  designed to align the  interests of the
executive  officers with those of  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.  The Primary  Stock
Option  Committee  had the sole  responsibility  for making option grants to the
Company's  executive  officers  during 1998. The Primary Stock Option  Committee
also  approved  the  guidelines  for option  grants made to other key  employees
during that fiscal  year.  Based on a review of  competitive  data,  the Primary
Stock Option  Committee  targeted  total option grants for 1998 to fall within a
range of 2.5% - 4.0% of total shares  outstanding.  Actual option grants, net of
cancellations,  for the fiscal year totaled 3.9% of the weighted  average number
of shares issued and outstanding. All stock options were granted at market price
on the date of grant and have a maximum term of ten years.

         The Primary Stock Option  Committee has established  guidelines for the
number  of  options  to  be  granted  to  each  level  of   executive   officer,
non-executive  management  and key individual  contributor  based on analysis of
competitive  data and internal  estimates of the number of options  necessary to
attract and retain these employees.  These guidelines were used to determine the
range of options to be granted to each  employee  through the  Company's  annual
grant  program.  The Primary  Stock  Option  Committee  applied its  judgment of
individual  performance,  with some  consideration  for the  number of  unvested
options held by an  individual,  when making  specific  grants to each executive
officer. These options will vest entirely in the fourth year after grant so that
generally the vesting will not overlap with previously granted options. In total
256,700  stock  options  were  granted in January  1998 to 12 current  executive
officers pursuant to the annual grant program.

         The Primary  Stock Option  Committee  deemed it in the best interest of
the Company to grant new options,  as a retention tool,  since it was clear that
there would be no cash bonuses paid during 1998.  Accordingly,  in January 1998,
the  Primary  Stock  Option  Committee  granted  420,708  options  to 12 current
executive  officers.  Each of these options  becomes  exercisable in a series of
installments  with 50% vesting one year following  grant date, and the remainder
vesting in successive 25% annual installments.

          On June 12, 1998, the Board of Directors approved a plan to cancel and
regrant options for the company's employees and officers effective July 1, 1998.
The Board believes that the current price of the Common Stock is attributable in
large part to adverse industry  conditions.  In addition the Board believes that
the  Company's  future  performance  is  dependent  in large part on the skills,
capabilities  and  efforts  of  the  Company's  employees,  especially  the  key
management  and  technical  employees  who hold the greatest  number of options.
Given the disparity between the exercise prices of then outstanding  options and
the  trading  prices  during the first two fiscal  quarters  of 1998,  the Board
believed  the  options  held  little  value  for  retention  and  motivation  of
employees.  The Board  remains  confident  it acted in the best  interest of the
Company and its  stockholders  in  authorizing  the  repricing.  Employees  were
permitted to voluntarily  exchange options held for new options on a one-for-one
basis. The price of the regranted  options was $5.3475 per share.  Officers were
required  to  forfeit  special  options  granted to them on October 6, 1997 as a
condition of accepting  regranted  options.  Regranted options retained the same
number of shares,  vested  amount and vesting  schedule as the original  grants;
however,  new options could not be exercised for a period of one year  following
the July 1, 1998  effective  date.  All of the 13  current  officers  elected to
participate in the July Option Regrant Program.

Compensation of the Chief Executive Officer and of the Chairman of the Board

         Base  salaries  of  Stephen  C.  Johnson  and Tu Chen for 1998  were at
approximately  the 30th  percentile of salaries paid to executives in comparable
positions at the peer companies, in accordance with the Compensation Committee's
target.  Neither Mr. Johnson nor Dr. Chen was granted merit  increases for 1998.
As no cash bonuses were paid for 1998 under the Company's plans, Mr. Johnson and
Dr. Chen received no variable  compensation during the year. Mr. Johnson and Dr.
Chen were each granted  stock  options for 113,500  shares  during the year.  In
addition,  Mr.  Johnson and Dr.  Chen  repriced  442,781  and  456,471  options,
respectively,  pursuant  to the July 1, 1998  Option  Cancellation  and  Regrant
Program authorized by the Board of Directors on June 12, 1998.


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  dollars 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,  with an exercise  price equal to the market  price of
Common Stock on the grant date, would qualify as performance-based compensation.
The Bonus Plan was restructured in 1996 and approved by stockholders so that the
payments   made  under  that  plan  would  also  qualify  as   performance-based
compensation  under  Section  162(m) and the Company  obtained a ruling from the
Internal  Revenue Service that the payments under the Bonus Plan will qualify as
performance-based compensation.  Stockholders subsequently approved an amendment
to the Bonus Plan in 1997, and future  payments  thereunder  should  continue to
qualify as performance-based  compensation that would not be subject to the Code
Section 162(m) limitation on deductibility.

         Each new  option  has a maximum  term of 10 years,  subject  to earlier
  termination upon the optionee's cessation of service.  Repriced options retain
  the remaining option term of the original grant at the time of repricing. 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 or permanent disability.  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.

(1)  Regranted  options vest according to the vesting  schedule of each original
     option grant.  All regranted  options are subject to the one-year  exercise
     blackout  period  imposed  under the terms of the July  1998  Stock  Option
     Cancellation and Regrant Program.  Unless otherwise noted, items dated July
     1, 1998 are regranted options.
(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  from the grant date and 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 5.5%;  volatility  factor of the expected  market price of the Company's
     Common Stock of 63.4%; and a weighted-average expected life of such options
     of 4.8 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  1998 was  $4.3885.  For officer
     grants  during  1998,  the  weighted-average  fair value of the options was
     $3.9945.
(5)  Indicates a new stock option granted July 1, 1998.
(6)  This option was granted on January 30, 1998 and was  subsequently  canceled
     in  connection  with the July 1, 1998  Option  Regrant.  Accordingly,  this
     option is no longer outstanding and has no potential  realizable value. See
     "Report  of  the  Compensation  and  Primary  Stock  Option  Committees  on
     Executive Compensation".

         The table  below sets forth  information  concerning  the  exercise  of
options during the 1998 fiscal year and  unexercised  options held as of the end
of such year by the Named Executive Officers.  No stock appreciation rights were
exercised during such fiscal year, and except for the limited stock appreciation
rights described  immediately  following the Option Grant Table above which form
part of each stock option grant, no stock  appreciation  rights were outstanding
at the end of such fiscal year.

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 January 3, 1999, 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.

         The  Board  of  Directors  knows  of no  other  business  that  will be
presented for consideration at the Annual Meeting. If other matters are properly
brought before the Annual Meeting,  however,  it is the intention of the persons
named in the accompanying proxy to vote the shares  represented  thereby on such
matters in accordance with their best judgment.

                               KOMAG, INCORPORATED

                        1988 EMPLOYEE STOCK PURCHASE PLAN

              (Restated June 29, 1992 and Amended January 27, 1994,
            January 22, 1997, January 30, 1998 and February 4, 1999)

 
       I.         PURPOSE

                  The Komag, Incorporated 1988 Employee Stock Purchase Plan (the
"Plan") is intended to provide eligible employees of the Company and one or more
of its  Corporate  Affiliates  with the  opportunity  to  acquire a  proprietary
interest in the Company through  participation  in a plan designed to qualify as
an employee stock  purchase plan under Section 423 of the Internal  Revenue Code
(the "Code").

      II.         DEFINITIONS

                  For  purposes of  administration  of the Plan,  the  following
terms shall have the meanings indicated:

                  Base Compensation  means (i) the regular base earnings paid to
a Participant by one or more Participating  Companies,  before deduction for any
contributions  made on the Participant's  behalf to any Code Section 401(k) Plan
maintained by the Company or any Corporate  Affiliate.  The  calculation of Base
Compensation  may also  include,  at the  discretion  of the Plan  Administrator
exercisable  prior to the start of any purchase period,  bonuses,  overtime pay,
shift  differentials  and  other  differentials.   Base  Compensation  shall  be
calculated on the basis of  equivalent  bi-weekly  straight-time  hours (up to a
maximum of 79.50 hours for  three-day  shift  employees  and 80.00 hours for all
other  employees)  multiplied  by  straight-time  rate.  In no event  shall Base
Compensation   include  any   profit-sharing   or  other   non-salary   deferral
contributions  made  on the  Participant's  behalf  pursuant  to  any  qualified
profit-sharing plan under Code Section 401(a).

                  Board means the Board of Directors of the Company.

                  Company means Komag, Incorporated, a Delaware corporation, and
any  corporate  successor  to all or  substantially  all of the assets or voting
stock of Komag, Incorporated, which shall by appropriate action adopt the Plan.

                  Corporate  Affiliate  means any  company  which is either  the
parent corporation or a subsidiary  corporation of the Company (as determined in
accordance  with Section 424 of the Code),  including  any parent or  subsidiary
corporation which becomes such after the Effective Date.

                  Effective   Date  means,   with   respect  to  the  1992  plan
restatement,  June 29, 1992.  However,  should any Corporate  Affiliate become a
Participating  Company in the Plan after such applicable  date, then such 

                                       

<PAGE>

entity  shall   designate  a  separate   Effective  Date  with  respect  to  its
employee-Participants.

                  Employee  means any person  who is  regularly  engaged,  for a
period of more than 20 hours per week for more than 5 months per calendar  year,
in the rendition of personal services to the Company or any other  Participating
Company for earnings considered wages under Section 3121(a) of the Code.

                  Fiscal Quarter means a three-month  period  corresponding to a
fiscal  quarter of the Company,  based on the  Company's  52-53 week fiscal year
ending on the Sunday closest to December 31st of each year.

                  Participant  means any  Employee  of a  Participating  Company
actively participating in the Plan.

                  Participating  Company  means the Company  and such  Corporate
Affiliate or Affiliates as may be designated from time to time by the Board. The
Participating  Companies in the Plan,  as of the Effective  Date,  are listed in
attached Schedule A.


                  Stock means shares of the common stock of the Company.

     III.         ADMINISTRATION

                  (a)  The  Plan  shall  be  administered  by a  committee  (the
"Committee")  comprised  of at  least  two  non-employee  members  of the  Board
appointed  from time to time by the Board.  The Committee as Plan  Administrator
shall  have full  authority  to  administer  the Plan,  including  authority  to
interpret  and  construe  any  provision of the Plan and to adopt such rules and
regulations  for  administering  the Plan as it may deem  necessary  in order to
comply  with  the  requirements  of Code  Section  423.  Decisions  of the  Plan
Administrator  shall be final and binding on all parties who have an interest in
the Plan.

                  (b) No member of the Committee  while serving as such shall be
eligible to participate in the Plan.

      IV.         PURCHASE PERIODS

                  (a) Stock shall be offered for purchase under the Plan through
a series of  successive  purchase  periods  until  such time as (i) the  maximum
number of shares of Stock  available for issuance under the Plan shall have been
purchased or (ii) the Plan shall have been sooner  terminated in accordance with
Article X or Article XI.

                  (b) The Plan shall be  implemented  in a series of  successive
purchase periods, each of such duration (not to exceed six months) as determined
by the  Plan  Administrator  prior to the  start  date of the  purchase  period.
Purchase periods will start, at the Plan Administrator's  discretion,  either



                                       2.
<PAGE>

on the first day or the first Monday of each  successive  Fiscal Quarter or each
alternate  successive  Fiscal Quarter.  Accordingly,  either four (4) or two (2)
separate purchase periods may commence per Fiscal Year.

                  (c) The Participant shall be granted a separate purchase right
for each purchase period in which he/she participates.  The purchase right shall
be granted on the first day of the  purchase  period and shall be  automatically
exercised  in (i)  successive  quarterly  installments  on the  last day of each
Fiscal  Quarter  such  purchase  right  remains  outstanding,  in the  case of a
purchase  period in which purchases are effected  quarterly,  or (ii) successive
semi-annual  installments on the last day of each alternate  Fiscal Quarter such
purchase right remains  outstanding,  in the case of a purchase  period in which
purchases are effected semi-annually.

                  (d) 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/she is  participating  and
must also enroll in the new purchase period prior to the  commencement  date for
that period.

                  (e) The acquisition of Stock through participation in the Plan
for any purchase period shall neither limit nor require the acquisition of Stock
by the Participant in any subsequent purchase period.  However,  the acquisition
of Stock  through  participation  in the Plan for any  purchase  period shall be
counted toward the  limitations on the number of purchasable  shares as provided
in Section VII(b) and the accrual limitations as provided in Section VIII.

                  (f) Under no  circumstances  shall any purchase rights granted
under the Plan be exercised,  nor shall any shares of Stock be issued hereunder,
until  such time as (i) the Plan  shall  have  been  approved  by the  Company's
shareholders  and (ii) the  Company  shall  have  complied  with all  applicable
requirements of the Securities Act of 1933 (as amended),  all applicable listing
requirements  of any  securities  exchange  on which the Stock is listed and all
other applicable requirements established by law or regulation.

       V.         ELIGIBILITY AND PARTICIPATION

                  (a)  Every  Employee  of  a  Participating  Company  shall  be
eligible  to  participate  in the Plan on the first  day of the  first  purchase
period following the Employee's  commencement of service with the Company or any
Corporate Affiliate,  but in no event shall participation  commence prior to the
Effective Date.

                  (b) In order  to  participate  in the  Plan  for a  particular
purchase  period,  the Employee must complete the enrollment forms prescribed by
the Plan  Administrator  (including a purchase agreement and a payroll deduction
authorization)  and  file  such  forms  with  the  Plan  Administrator  (or  its
designate)  prior  to  the  commencement  date  of  the  purchase  period.  Such
enrollment  shall be effective for  subsequent,  but not  overlapping,  purchase
periods,  unless the Employee notifies the Plan Administrator (or its designate)
to the contrary prior to the commencement  date of any such subsequent  purchase
period.

                                       3.
<PAGE>

                  (c) The payroll  deduction  authorized  by a  Participant  for
purposes of acquiring Stock under the Plan may be any multiple of 1% of the Base
Compensation paid to the Participant  during the relevant purchase period, up to
a maximum of 10%. The deduction rate so authorized  shall continue in effect for
the entire purchase period and for each subsequent  purchase period,  unless the
Participant  shall,  prior  to the end of the  purchase  period  for  which  the
purchase right is in effect, reduce the rate by filing the appropriate form with
the Plan  Administrator  (or its  designate).  The  reduced  rate  shall  become
effective  as soon as  practicable  following  the  filing  of such  form.  Each
Participant  shall be permitted such a rate reduction only two (2) times in each
purchase  period.  The  reduced  rate  shall  continue  in effect for the entire
purchase period and for each subsequent purchase period,  unless the Participant
shall,  prior to the commencement of any subsequent  purchase period designate a
different rate (up to the 10% maximum) by filing the  appropriate  form with the
Plan  Administrator (or its designate).  The new rate shall become effective for
the first  purchase  period  commencing  after the filing of such form.  Payroll
deductions,  however,  will  automatically  cease  upon the  termination  of the
Participant's purchase right in accordance with Section VII(d) or (e) below.

      VI.         STOCK SUBJECT TO PLAN

                  (a) The  Stock  purchasable  by  Participants  under  the Plan
shall,  solely  in  the  Board's  discretion,  be  made  available  from  either
authorized  but unissued Stock or from  reacquired  Stock,  including  shares of
Stock  purchased on the open  market.  The total number of shares of Stock which
may be issued  under the Plan  shall not exceed  7,400,000  shares  (subject  to
adjustment under Section VI(b)). Such share reserve includes the 2,550,000-share
increase  authorized  by the Board on February 4, 1999,  subject to  stockholder
approval at the 1999 Annual Meeting.

                  (b) In the event any  change is made to the Stock  purchasable
under the Plan by reason of any recapitalization,  stock dividend,  stock split,
combination of shares or other change affecting the outstanding  common stock of
the  Company as a class  without  receipt  of  consideration,  then  appropriate
adjustments  shall be made by the Plan  Administrator  to the class and  maximum
number of shares  purchasable  under the Plan,  the class and maximum  number of
shares  purchasable per Participant  under any purchase right outstanding at the
time or purchasable per Participant over the term of the Plan, and the class and
number of shares  and the price per share of the Stock  subject  to  outstanding
purchase rights held by Participants under the Plan.

     VII.         PURCHASE RIGHTS

                  An  Employee  who  participates  in the Plan for a  particular
purchase  period shall have the right to purchase  Stock on the  purchase  dates
designated by the Plan Administrator for such purchase period upon the terms and
conditions set forth below and shall execute a purchase agreement embodying such
terms and conditions and such other provisions (not  inconsistent with the Plan)
as the Plan Administrator may deem advisable.

                  (a) Purchase Price.  The purchase price per share shall be the
lesser  of (i) 85% of the fair  market  value of a share of Stock on the date on
which the  purchase  right is granted or (ii) 85%


                                       4
<PAGE>

of the fair market value of a share of Stock on the date the  purchase  right is
exercised. For purposes of determining such fair market value (and for all other
valuation  purposes under the Plan), the fair market value per share of Stock on
any date shall be determined in accordance with the following provisions:

                    (i) If the Stock is not at the time  listed or  admitted  to
          trading on any stock  exchange  but is traded on the  Nasdaq  National
          Market,  the fair market value per share shall be the closing  selling
          price per share of Stock on the date in  question,  as such prices are
          reported by the  National  Association  of  Securities  Dealers on the
          Nasdaq National Market.  If there is no reported closing selling price
          on the  date  in  question,  then  the  closing  selling  on the  last
          preceding date for which such quotation  exists shall be determinative
          of fair market value.

                    (ii) If the  Stock  is at the time  listed  or  admitted  to
          trading on any stock exchange, then the fair market value shall be the
          closing  selling  price per share of Stock on the date in  question on
          the stock  exchange  determined  by the Plan  Administrator  to be the
          primary  market for the Stock,  as such price is officially  quoted on
          such exchange.  If there is no reported sale of Stock on such exchange
          on the  date in  question,  then the fair  market  value  shall be the
          closing  selling price on the exchange on the last  preceding date for
          which such quotation exists.

                  (b)  Number  of  Purchasable  Shares.  The  number  of  shares
purchasable by a Participant on any particular purchase date shall be the number
of whole shares  obtained by dividing the amount  collected from the Participant
through payroll  deductions during the quarterly or semi-annual period beginning
with the start of the purchase  period or the most recent  purchase  date in the
same purchase period (whichever is applicable), together with any amount carried
over from the preceding  purchase date in the same purchase  period  pursuant to
the  provisions  of Section  VII(f),  by the  purchase  price in effect for such
purchase  date.  However,  the  maximum  number  of  shares  purchasable  by the
Participant on any purchase date shall not exceed 3,000 shares, in the case of a
purchase period in which purchases are effected  quarterly,  or 6,000 shares, in
the case of a purchase  period in which  purchases  are  effected  semi-annually
(subject in either instance to adjustment under Section VI(b)). In addition, the
maximum  number of shares  for which  purchase  rights may in the  aggregate  be
granted to any individual who is subject to the short-swing profit  restrictions
of the  Federal  securities  laws shall not exceed  50,000  shares  (subject  to
adjustment under Section VI(b)) over the term of the Plan. Accordingly,  no such
officer  or  director  shall be  eligible  to  receive  purchase  rights for any
purchase  period if the number of shares which would otherwise be purchasable by
such  individual  for that purchase  period would result in the issuance to such
individual  of  shares  of Stock in  excess  of the  maximum  number  of  shares
purchasable in the aggregate by such  individual over the term of the Plan. Each
of the foregoing  share-limitations has been adjusted to reflect the two-for-one
forward split of the Stock effected on December 21, 1995.

                  Under no circumstances  shall purchase rights be granted under
the Plan to any 

                                       5.
<PAGE>

Employee if such Employee would,  immediately  after the grant,  own (within the
meaning of Section  424(d) of the Code),  or hold  outstanding  options or other
rights to purchase,  stock  possessing 5% or more of the total  combined  voting
power or value of all  classes of stock of the  Company or any of its  Corporate
Affiliates.

                  (c) Payment.  Payment for Stock purchased under the Plan shall
be effected by means of the Participant's  authorized payroll  deductions.  Such
deductions  shall  begin on the first  pay day  coincident  with or  immediately
following  the  commencement  date of the  relevant  purchase  period  and shall
terminate with the pay day ending with or  immediately  prior to the last day of
the  purchase  period.  The  amounts  so  collected  shall  be  credited  to the
Participant's  individual  account under the Plan, but no interest shall be paid
on the  balance  from  time to time  outstanding  in the  account.  The  amounts
collected  from a Participant  may be commingled  with the general assets of the
Company and may be used for general corporate purposes.

                  (d)      Termination of Purchase Rights.

                        (i) A  Participant  may,  prior  to any  purchase  date,
terminate  his/her  outstanding  purchase  right  under the Plan by  filing  the
prescribed notification form with the Plan Administrator (or its designate). The
Company will then refund all sums previously  collected from the Participant and
not previously  applied to the purchase of Stock during the purchase period, and
no further  amounts will be collected from the  Participant  with respect to the
terminated purchase right.

                        (ii) The termination  shall be irrevocable  with respect
to the  particular  purchase  period to which it pertains and shall also require
the  Participant  to re-enroll  in the Plan (by making a timely  filing of a new
purchase  agreement  and payroll  deduction  authorization)  if the  Participant
wishes to resume participation in a subsequent purchase period.

                  (e)  Termination  of  Employment.   If  a  Participant  ceases
Employee status during any purchase period,  then the Participant's  outstanding
purchase  right  under  the  Plan  shall  immediately  terminate  and  all  sums
previously  collected from the  Participant  and not  previously  applied to the
purchase  of stock  during such  purchase  period  shall be  promptly  refunded.
However,  should the  Participant  die or become  permanently  disabled while in
Employee  status,  then the  Participant  or the  person or  persons to whom the
rights of the deceased  Participant under the Plan are transferred by will or by
the laws of descent and distribution  (the  "successor") will have the election,
exercisable  at any  time  prior  to the  purchase  date  for the  quarterly  or
semi-annual  period  in  which  the  Participant  dies  or  becomes  permanently
disabled,  to (i) withdraw all the funds in the Participant's payroll account at
the time of his/her cessation of Employee status or (ii) have such funds applied
to the  purchase  of shares  of Stock on the next  purchase  date.  In no event,
however,  shall any further  payroll  deductions  be added to the  Participant's
account following his/her cessation of Employee status.

                  For  purposes  of  the  Plan:  (a)  a  Participant   shall  be
considered  to be an  Employee  for so long as such  Participant  remains in the
employ of the Company or any other Participating  Company under the Plan and (b)
a Participant shall be deemed to be permanently disabled if he/she is unable, by
reason of any medically  determinable  physical or mental impairment expected to
result in death or to be of continuous  duration of at least twelve (12) months,
to engage in any substantial gainful employment.

                                       6.
<PAGE>

                  (f)  Stock  Purchase.  Outstanding  purchase  rights  shall be
automatically  exercised in a series of successive  installments  as provided in
Section IV(c). The exercise shall be effected by applying the amount credited to
the Participant's account on the last date of the Fiscal Quarter, in the case of
a purchase period in which purchases are effected quarterly, or the last date of
the  alternate  Fiscal  Quarter,  in the  case of a  purchase  period  in  which
purchases are effected  semi-annually,  to the purchase of whole shares of Stock
(subject to the  limitations  on the maximum  number of  purchasable  shares set
forth in Section VII(b)) at the purchase price in effect for such purchase date.
Any amount remaining in the  Participant's  account after such purchase shall be
held for the  purchase of Stock on the next  quarterly or  semi-annual  purchase
date within the purchase period; provided,  however, that any amount not applied
to the  purchase  of Stock at the end of a  purchase  period  shall be  refunded
promptly after the close of the purchase  period,  and any amount not applied to
the purchase of stock by reason of the Section VII(b) limitations on the maximum
number of purchasable  shares shall be refunded  promptly after the quarterly or
semi-annual purchase date.

                  (g) Proration of Purchase  Rights.  Should the total number of
shares of Stock  which are to be  purchased  pursuant  to  outstanding  purchase
rights on any  particular  date exceed the number of shares then  available  for
issuance under the Plan, the Plan Administrator shall make a pro-rata allocation
of the  available  shares  on a uniform  and  nondiscriminatory  basis,  and any
amounts  credited  to the  accounts  of  Participants  shall,  to the extent not
applied to the purchase of Stock, be refunded to the Participants.

                  (h) Rights as Shareholder.  A Participant shall have no rights
as a shareholder  with respect to shares covered by the purchase  rights granted
to the Participant under the Plan until the shares are actually purchased on the
Participant's  behalf in accordance with Section VII(f). No adjustments shall be
made for dividends,  distributions  or other rights for which the record date is
prior to the date of such purchase.

                  A  Participant  shall  be  entitled  to  receive,  as  soon as
practicable after the date of each purchase,  stock  certificates for the number
of shares purchased on the Participant's  behalf. Such certificate may, upon the
Participant's  request,  be issued in the names of the  Participant  and his/her
spouse as community property or as joint tenants with right of survivorship.

                  In lieu of delivering a stock certificate to each Participant,
the Plan  Administrator  may, in its discretion,  implement a designated  broker
program and direct the Company to issue a single stock  certificate  to a broker
designated by the Plan Administrator.  Such designated broker shall establish an
account for each  Participant  in the Plan and shall effect  transfers and sales
from such  account  at the  direction  of the  Participant.  To  facilitate  the
designated broker program, the Plan Administrator may require, as a condition to
participation  in the Plan,  that a Participant  agree to the issuance of his or
her stock certificates directly to the designated broker.

                  (i)  Assignability.  No purchase rights granted under the Plan
shall be assignable or  transferable  by a Participant  except by will or by the
laws of descent and  distribution,  and the purchase  rights  shall,  during the
lifetime of the Participant, be exercisable only by such Participant.

                                       7.

                  (j) Merger or Liquidation of Company. In the event the Company
or its  shareholders  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 (other than a reorganization  effected primarily to change the State
in which the Company is incorporated) or in the event the Company is liquidated,
then all  outstanding  purchase  rights  under the Plan shall  automatically  be
exercised immediately prior to such sale, merger,  reorganization or liquidation
by applying all sums previously  collected from  Participants  pursuant to their
payroll  deductions in effect for such rights to the purchase of whole shares of
Common Stock, subject, however, to the applicable limitations of Section VII(b).

    VIII.         ACCRUAL LIMITATIONS

                  (a) No  Participant  shall be  entitled  to  accrue  rights to
acquire  Stock  pursuant  to any  purchase  right  under this Plan if and to the
extent such accrual,  when  aggregated with (I) Stock rights accrued under other
purchase  rights  outstanding  under this Plan and (II) similar  rights  accrued
under other  employee stock purchase plans (within the meaning of Section 423 of
the Code) of the Company or its Corporate  Affiliates,  would  otherwise  permit
such  Participant to purchase more than $25,000 worth of stock of the Company or
any  Corporate  Affiliate  (determined  on the basis of the fair market value of
such stock on the date or dates such rights are granted to the  Participant) for
each calendar year such rights are at any time outstanding.

                  (b) For  purposes  of  applying  the  accrual  limitations  of
Section  VIII(a),   the  right  to  acquire  Stock  under  each  purchase  right
outstanding under the restated Plan shall accrue as follows:

                          - The right to acquire  Stock under each such purchase
         right shall accrue in a series of successive  quarterly or  semi-annual
         installments  as and when the purchase right first becomes  exercisable
         for each installment as provided in Section IV(c).

                          - No right to  acquire  Stock  under  any  outstanding
         purchase right shall accrue to the extent the  Participant  has already
         accrued in the same calendar year the right to acquire Stock under that
         purchase right or any other purchase  rights held by the Participant at
         the rate of $25,000  worth of Stock  (based on the fair market value on
         the date or dates of grant) for each calendar year (or portion thereof)
         for which such purchase rights have been outstanding.

                          - If by reason of the Section VIII(a) limitations, the
         Participant's   outstanding  purchase  right  does  not  accrue  for  a
         particular  purchase  date of any  purchase  period,  then the  payroll
         deductions   which  the  Participant  made  during  that  quarterly  or
         semi-annual  period  with  respect  to such  purchase  right  shall  be
         promptly refunded.

                                       8.
<PAGE>

                  (c) In the event there is any conflict  between the provisions
of this Article VIII and one or more  provisions  of the Plan or any  instrument
issued thereunder, the provisions of this Article VIII shall be controlling.

      IX.         STATUS OF PLAN UNDER FEDERAL TAX LAWS

                  (a) The Plan is  designed  to  qualify  as an  employee  stock
purchase plan under Code Section 423. However,  the Plan  Administrator  may, at
any time in its discretion, cease to administer the Plan as a qualified employee
stock  purchase  plan under  Code  Section  423.  Accordingly,  share  purchases
effected under the Plan at any time after the Plan ceases to be  administered as
a  qualified  employee  stock  purchase  plan under Code  Section  423  (whether
pursuant  to  purchase  rights  granted  before or after  the Plan  ceases to be
qualified)  shall  result in  taxable  income to each  Participant  equal to the
excess of (i) the fair market value of the purchased shares on the purchase date
over (ii) the purchase price paid for such shares.

                  (b) To the extent required by law, the Company's obligation to
deliver shares to the Participant upon the exercise of any outstanding  purchase
right  shall be  subject to the  Participant's  satisfaction  of all  applicable
federal, state and local income and employment tax withholding requirements.

       X.         AMENDMENT AND TERMINATION

                  (a) The Board may from time to time alter,  amend,  suspend or
discontinue  the Plan;  provided,  however,  that no such  action  shall  become
effective prior to the exercise of outstanding purchase rights at the end of the
quarterly  or  semi-annual  period  in which  such  action  is  authorized;  and
provided, further, that no such action of the Board may, without the approval of
the  shareholders  of the Company,  increase the number of shares issuable under
the Plan or the maximum number of shares which any one  Participant may purchase
during a single  purchase  period  or over  the  term of the  Plan  (except  for
adjustments  permitted under Section VI(b)), alter the purchase price formula so
as to reduce the  purchase  price  specified in the Plan,  otherwise  materially
increase  the benefits  accruing to  Participants  under the Plan or  materially
modify the requirements for eligibility to participate in the Plan.

                  (b) The Company shall have the right,  exercisable in the sole
discretion  of  the  Plan  Administrator,  to  terminate  the  Plan  immediately
following  the end of a  quarterly  or  semi-annual  purchase  date.  Should the
Company  elect to exercise  such  right,  then the Plan shall  terminate  in its
entirety,  and no further  purchase rights shall  thereafter be granted,  and no
further payroll deductions shall thereafter be collected, under the Plan.

      XI.         GENERAL PROVISIONS

                  (a) The Plan was initially adopted by the Board on January 21,
1988 and approved by the  stockholders  on June 7, 1988.  In January  1991,  the
Board approved a 250,000-share  increase in the number of shares of Common Stock
issuable  under the Plan,  and the  stockholders  approved  such



                                       9.
<PAGE>

increase in May 1991.  The 1992  restatement  of the Plan and the  250,000-share
increase approved by the Board on January 23, 1992 became effective on the first
day of the first purchase period which began after the 1992 Annual  Stockholders
Meeting.  Additional  amendments  were  made to the Plan on  January  27,  1994,
January 22, 1997, and January 30, 1998 to increase the number of shares of Stock
reserved  for  issuance  under the Plan,  and the January  1997  amendment  also
extended  the term of the Plan to December 31,  2001.  On February 4, 1999,  the
Board  authorized  an  amendment to the Plan to increase the number of shares of
Stock  available  for issuance  hereunder  by an  additional  2,550,000  shares,
subject to stockholder  approval at the 1999 Annual Meeting. If such stockholder
approval  is not  obtained,  then no purchase  rights will be granted  under the
Purchase Plan on the basis of the 2,550,000-share increase.

                  (b) The  provisions  of this restated Plan shall apply only to
purchase  rights  exercised  under the Plan from and after the Effective Date of
such restatement.  All exercises effected under the Plan prior to such Effective
Date were governed by the terms and  conditions of the Plan as in effect on each
such exercise  date, and nothing in this restated Plan shall be deemed to affect
or otherwise  modify the rights or  obligations  of the holders of the shares of
Common Stock acquired thereunder.

                  (c) The Plan shall  terminate upon the earlier of (i) December
31, 2001 or (ii) the date on which all shares  available for issuance  under the
Plan shall have been sold pursuant to purchase rights exercised under the Plan.

                  (d) All costs and expenses  incurred in the  administration of
the Plan shall be paid by the Company.

                  (e)  Neither  the action of the  Company in  establishing  the
Plan,  nor any action  taken under the Plan by the Plan  Administrator,  nor any
provision  of the Plan itself  shall be  construed so as to grant any person the
right to remain in the employ of the Company or any of its Corporate  Affiliates
for any  period  of  specific  duration,  and such  person's  employment  may be
terminated at any time, with or without cause.

                  (f) The  provisions  of the Plan shall be governed by the laws
of the State of California.

                         RESTATED 1987 STOCK OPTION PLAN

                  (Amended and Restated through April 16, 1999)


                                   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.




<PAGE>

     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 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),



                                      2.
<PAGE>

               - 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.


     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.



                                       3.

     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).

          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.


                                       4.
<PAGE>

          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.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM

     VI.  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.

                                       6.
<PAGE>

                    (iv) to the  extent  the  option  is  exercised  for  vested
               shares, 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  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
               sales 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  sales price for the Common Stock on the date
               in  question,  then the fair  market  value  shall be the closing
               sales 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  sales 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  sales  price for the
               Common Stock on the date in question,  then the fair market value
               shall be the closing sales 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,  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.



                                       8.
<PAGE>

               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 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.



                                       9.

               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.

          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.



                                      10.
<PAGE>

          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.

     VII. 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"  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.

                                      11.
<PAGE>

          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  more than 10% 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.

     VIII. 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,

          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.

                                      12.
<PAGE>

          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.

     IX. 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  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.

                                      13.
<PAGE>

          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 Take-Over.  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.

     X.  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 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.

                                  ARTICLE THREE

                         AUTOMATIC OPTION GRANT PROGRAM


     XI.  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.

     XII.  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 1999 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  12,000  shares of the Common  Stock,  provided  such
          individual has been a member of the Board for at least six (6) months.

                                      15.
<PAGE>

                  The applicable  30,000-share and  12,000-share  limitations on
the automatic option grants to be made to non-employee  Board members under this
Article Three shall 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.

          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  12,000-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.



                                      17.
<PAGE>

               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 1999 Annual Stockholders  Meeting shall be assignable in whole or in part by
the optionee during his or her lifetime,  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.



                                      18.
<PAGE>

               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. 


XIII. 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).



                                      19.
<PAGE>

          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 (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 1999  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.

                                  MISCELLANEOUS

     XIV.  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.

     XV.  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 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.



                                      21.
<PAGE>

          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 was  approved  by
stockholders at the 1997 Annual Meeting.


          E. On April 16,  1999,  the Board  amended  and  restated  the Plan to
effect  an  increase  in the  number  of stock  options  granted  to  re-elected
non-employee  Board  members  under the  Automatic  Grant  Program from 7,500 to
12,000 shares annually.  The 1999 restatement of the Plan is subject to approval
by stockholders at the 1999 Annual Meeting.

          F. 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.


          G. 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.


          H. 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.

          I. 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.

                                      22.

     XVI.  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.

     XVII. 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.

     XVIII.  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.


     XIX.  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.
