                                 PROXY STATEMENT

                    FOR THE ANNUAL MEETING OF STOCKHOLDERS OF
                               SANDISK CORPORATION
                             TO BE HELD May 12, 1999



                                     GENERAL

This Proxy  Statement is furnished in connection  with the  solicitation  by the
Board of Directors of SanDisk Corporation, a Delaware corporation (the "Company"
or "SanDisk"), of proxies to be voted at the Annual Meeting of Stockholders (the
"Annual  Meeting")  to be  held  on  May  12,  1999,  or at any  adjournment  or
postponement  thereof,  for the purposes set forth in the accompanying Notice of
Annual Meeting of Stockholders. Stockholders of record on March 15, 1999 will be
entitled to vote at the Annual Meeting.  The Annual Meeting will be held at 9:00
a.m., local time, at the Company's  headquarters,  140 Caspian Court, Sunnyvale,
California 94089.

It is anticipated  that this Proxy Statement and the enclosed proxy card will be
first mailed to stockholders on or about April 9, 1999.

                                  VOTING RIGHTS

The close of business  on March 15,  1999 was the record  date for  stockholders
entitled  to notice of and to vote at the Annual  Meeting  and any  adjournments
thereof. At the record date, the Company had approximately  26,819,100 shares of
its Common Stock outstanding and entitled to vote at the Annual Meeting, held by
approximately  212 stockholders of record.  Holders of Common Stock are entitled
to one  vote for  each  share of  Common  Stock  so  held.  In the  election  of
Directors,  however, cumulative voting is authorized for all stockholders if any
stockholder  gives  notice at the  meeting,  prior to voting for the election of
Directors, of his or her intention to cumulate votes. Under cumulative voting, a
stockholder  may cumulate  votes and give to one nominee a number of votes equal
to the number of Directors to be elected  (seven at this meeting)  multiplied by
the number of votes to which such  stockholder  is entitled,  or may  distribute
such number among any or all of the nominees. The seven candidates receiving the
highest  number of votes will be elected.  The Board of Directors is  soliciting
discretionary  authority to vote proxies cumulatively.  A majority of the shares
of Common Stock entitled to vote will constitute a quorum for the transaction of
business at the Annual Meeting.

If any stockholder is unable to attend the Annual Meeting,  such stockholder may
vote by  proxy.  The  enclosed  proxy is  solicited  by the  Company's  Board of
Directors, (the "Board of Directors" or the "Board") and, when the proxy card is
returned properly completed,  it will be voted as directed by the stockholder on
the proxy card.  Stockholders are urged to specify their choices on the enclosed
proxy card. If a proxy card is signed and returned without choices specified, in
the absence of contrary instructions,  the shares of Common Stock represented by
such  proxy will be voted FOR  Proposals  1, 2, 3, 4, and 5 and will be voted in
the proxy holders'  discretion as to other matters that may properly come before
the Annual Meeting.

An  affirmative  vote of a plurality of the shares present or represented at the
meeting and voting is required for the  election of  directors.  An  affirmative
vote of a majority  of the shares  present or  represented  at the  meeting  and
entitled to vote is required for the approval of each of the other proposals. An
automated  system   administered  by  the  Company's  transfer  agent  tabulates
stockholder  votes.  Abstentions  and  broker  non-votes  each are  included  in
determining  the number of shares  present and voting at the Annual  Meeting for
purposes  of  determining  the  presence  or  absence  of a quorum,  and each is
tabulated separately.  Abstentions are counted as negative votes, whereas broker
non-votes are not counted for purposes of determining  whether Proposals 2, 3, 4
and 5 presented to stockholders have been approved.

                                       4



                             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 an
instrument of  revocation  or a duly executed  proxy bearing a later date, or by
attending the Annual Meeting and voting in person.

                             SOLICITATION OF PROXIES

The Company will bear the cost of  soliciting  proxies.  Copies of  solicitation
material  will be furnished to brokerage  houses,  fiduciaries,  and  custodians
holding shares in their names that are  beneficially  owned by others to forward
to such  beneficial  owners.  The Company may  reimburse  such persons for their
costs of forwarding the  solicitation  material 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 intend to solicit proxies other
than by mail.

THE ANNUAL REPORT OF THE COMPANY FOR THE FISCAL YEAR ENDED DECEMBER 27, 1998 HAS
BEEN MAILED  CONCURRENTLY  WITH THE MAILING OF THE NOTICE OF ANNUAL  MEETING AND
PROXY  STATEMENT  TO ALL  STOCKHOLDERS  ENTITLED TO NOTICE OF AND TO VOTE AT THE
ANNUAL MEETING.  THE ANNUAL REPORT IS NOT INCORPORATED INTO THIS PROXY STATEMENT
AND IS NOT CONSIDERED PROXY SOLICITING MATERIAL.

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

                                 PROPOSAL NO. 1:

                              ELECTION OF DIRECTORS
                       -----------------------------------

At the Annual Meeting, seven directors (constituting the entire board) are to be
elected  to serve  until the next  Annual  Meeting of  Stockholders  and until a
successor  for such  director  is  elected  and  qualified,  or until the death,
resignation,  or removal of such director.  It is intended that the proxies will
be voted for the seven nominees named below for election to the Company's  Board
of Directors  unless  authority to vote for any such nominee is withheld.  There
are seven nominees,  each of whom is currently a director of the Company. All of
the current directors, other than Mr. Mulvaney, were elected to the Board by the
stockholders at the last annual meeting.  Each person nominated for election has
agreed to serve if elected,  and the Board of Directors has no reason to believe
that any nominee will be  unavailable  or will  decline to serve.  In the event,
however,  that any  nominee is unable or  declines to serve as a director at the
time of the Annual  Meeting,  the  proxies  will be voted for any nominee who is
designated  by the  current  Board  of  Directors  to fill the  vacancy.  Unless
otherwise  instructed,  the proxyholders  will vote the proxies received by them
FOR the nominees named below. The seven candidates  receiving the highest number
of the  affirmative  votes of the shares  entitled to vote at the Annual Meeting
will be elected  directors of the Company.  The proxies  solicited by this Proxy
Statement may not be voted for more than seven nominees.


                                    NOMINEES


         Set forth below is  information  regarding the nominees to the Board of
Directors.

                          BOARD MEETINGS AND COMMITTEES

The Board of Directors held five meetings during fiscal 1998. Each member of the
Board of  Directors  during  fiscal 1998  attended or  participated  in at least
seventy-five  percent  (75%) or more of the aggregate of (i) the total number of
meetings  of the Board of  Directors  held  during the fiscal  year and (ii) the
total number of meetings held by all  committees  on which such director  served
during the past fiscal year. There are no family  relationships  among executive
officers  or  directors  of the  Company.  The Board of  Directors  has an Audit
Committee and a Compensation Committee.

The Audit  Committee of the Board of Directors  held two meetings  during fiscal
1998. The Audit Committee,  which is currently  comprised of Directors Federman,
Lego  and  Mulvaney,   recommends   engagement  of  the  Company's   independent
accountants,  approves  services  performed by such  accountants and reviews and
evaluates the Company's accounting system and its system of internal controls.

The  Compensation  Committee of the Board of Directors held four meetings during
fiscal  1998 and  approved  grants of options  by  written  consent on a monthly
basis. The Compensation Committee,  which is comprised of Directors Campbell and
Shugart, has overall  responsibility for the Company's compensation policies and
determines  the  compensation  payable  to  the  Company's  executive  officers,
including their  participation in certain of the Company's  employee benefit and
stock option plans.

                              DIRECTOR COMPENSATION

Board  members do not  receive  any cash  compensation  for their  services as a
director.  Board  members are also not  compensated  for their  service on Board
committees  or  their   performance  of  special   assignments.   However,   the
non-employee  Board members are eligible to receive periodic option grants under
the 1995  Non-Employee  Directors Stock Option Plan (the "Directors  Plan").  In
addition,  Dr.  Meindl is paid  $10,000  per annum in his  capacities  as Senior
Technical advisor to the Company,  and Ms. Lego is paid $10,000 per annum in her
capacity as Financial Advisor to the Company.

Under the Directors Plan, as in effect during the 1998 fiscal year, Mr. Mulvaney
received an option grant for 16,000 shares of Common Stock at an exercise  price
of $9.50 per share on October 22, 1998 in connection with his appointment to the
Board  as  a  non-employee  director.  In  addition,  each  individual  who  was
re-elected as a non-employee Board member at the 1998 Annual Meeting received at
that time an option grant under the Directors  Plan to purchase  4,000 shares of
Common Stock, provided such individual had served as a non-employee Board member
for at least six months.  Accordingly,  each of the following non-employee Board
members  re-elected to the Board at the 1998 Annual  Meeting  received an option
grant  for  4,000  shares on April 30,  1998,  the date of that  meeting,  at an
exercise price of $20.875 per share: Messrs. Federman,  Campbell,  Meindl, Rizzi
and Shugart and Ms. Lego.

Each  automatic  grant has an exercise  price per share equal to the fair market
value per share of Common  Stock on the grant date and has a maximum  term of 10
years,  subject to earlier  termination  following the  optionee's  cessation of
Board service.  Each automatic option is immediately  exercisable for any or all
of the option shares;  however,  any shares  purchased  under the option will be
subject to  repurchase  by the Company,  at the option  exercise  price paid per
share,  should the optionee  cease service as a Board member prior to vesting in
those shares.  The shares subject to the 16,000 share grant made to Mr. Mulvaney
will vest in four successive equal annual  installments over his period of Board
service,  with the first  installment to vest upon his completion of one year of
Board  service  measured  from the grant date.  The shares  subject to the 4,000
share grant made to each non-employee Board member re-elected at the 1998 Annual
Meeting will vest upon the  optionee's  completion  of one year of Board service
measured from the grant date.  However,  the shares subject to each  outstanding
option  will  immediately  vest upon (i)  certain  changes in the  ownership  or
control of the Company or (ii) the death or  disability  of the  optionee  while
serving as a Board member.  In addition,  each automatic  option grant may, upon
the successful  completion of a hostile tender offer for more than fifty percent
(50%) of the Company's  outstanding  common stock, be surrendered to the Company
for a cash distribution per surrendered  option share equal to the excess of (i)
the highest price per share of common stock paid in connection  with such tender
offer ver (ii) the exercise price payable per share.

A number of substantial revisions will be made to the Directors Plan if Proposal
No. 3 is approved by the stockholders at the Annual Meeting.  Please review that
proposal for further information concerning those changes.

              THE BOARD OF DIRECTORS  RECOMMENDS THAT THE STOCKHOLDERS  VOTE FOR
THE ELECTION OF ALL OF THE ABOVE NOMINEES.






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

                                 PROPOSAL NO. 2:

                              APPROVAL OF AMENDMENT
                          TO THE 1995 STOCK OPTION PLAN
                     ---------------------------------------

The  Company's  stockholders  are being  asked to  approve an  amendment  to the
Company's  1995 Stock Option Plan (the "Option Plan") that will (i) increase the
maximum  number of shares of Common Stock  authorized for issuance over the term
of the Option  Plan by an  additional  3,500,000  shares and (ii)  implement  an
automatic  share  increase  feature  pursuant  to which  the  number  of  shares
available for issuance under the Option Plan will automatically  increase on the
first trading day in January each calendar  year,  beginning  with calendar year
2002 and  continuing  over the  remaining  term of the Option Plan, by an amount
equal to four and thirty-six  hundredths  percent (4.36%) of the total number of
shares  outstanding  on the last  trading  day in  December  in the  immediately
preceding  calendar year, but in no event will any such annual  increase  exceed
2,000,000 shares.

The  amendment  will  assure  that a  sufficient  reserve  of Common  Stock will
continue  to be  available  under the  Option  Plan to  attract  and  retain the
services of key  individuals  essential to the  Company's  long-term  growth and
success.  The amendment was adopted by the Board in December,  1998,  subject to
stockholder approval at the 1999 Annual Meeting.

The  following  is a summary  of the  principal  features  of the  Option  Plan,
together with the applicable tax and accounting  implications,  which will be in
effect if the  amendment  to the Option Plan is  approved  by the  stockholders.
However,  the summary does not purport to be a complete  description  of all the
provisions  of the Option  Plan.  Any  stockholder  of the Company who wishes to
obtain a copy of the actual plan document may do so upon written  request to the
Secretary at the Company's principal executive offices in Sunnyvale, California.

Administration

The Option Plan is administered by the Compensation  Committee of the Board. The
Compensation  Committee  acting  in  such  administrative  capacity  (the  "Plan
Administrator") has complete discretion (subject to the provisions of the Option
Plan) to authorize option grants under the Option Plan.

Share Reserve

A total of 9,498,711  shares of Common Stock has been reserved for issuance over
the ten (10)-year term of the Option Plan including the 3,500,000-share increase
for which  stockholder  approval  is sought  as part of this  Proposal  No 2. In
addition,  upon  stockholder  approval  of this  Proposal,  the number of shares
available for issuance under the Option Plan will automatically  increase on the
first trading day in January each calendar  year,  beginning  with calendar year
2002 and  continuing  over the  remaining  term of the Option Plan, by an amount
equal to four and thirty-six  hundredths  percent (4.36%) of the total number of
shares of Common  Stock  outstanding  on the last trading day in December in the
immediately  preceding  calendar  year,  but in no event  will  any such  annual
increase exceed 2,000,000 shares.

No  participant  in the Option Plan may be granted stock options and  separately
exercisable  stock  appreciation  rights for more than  1,000,000  shares in the
aggregate under the Option Plan, and stockholder  approval of this Proposal will
also constitute re-approval of that limitation.

Should an option  expire or terminate  for any reason prior to exercise in full,
the shares  subject  to the  portion  of the  option  not so  exercised  will be
available for subsequent  issuance under the Option Plan. Unvested shares issued
under  the  Option  Plan and  subsequently  repurchased  by the  Company  at the
original  option or issue  price  paid per share will be added back to the share
reserve and will  accordingly  be available for  subsequent  issuance  under the
Plan.  However,  should the exercise price of an option under the Option Plan be
paid with  shares of Common  Stock or should  shares of Common  Stock  otherwise
issuable under the Option Plan be withheld by the Company in satisfaction of the
withholding taxes incurred in connection with the exercise of an

                                       9



option,  then  the number of shares of Common Stock available for issuance under
the Plan will be reduced  by the gross  number of shares for which the option is
exercised  and not by the net  number  of  shares  issued  to the  holder of the
option.

Changes in Capitalization

In the event any  change is made to the  outstanding  shares of Common  Stock by
reason of any  recapitalization,  stock  dividend,  stock split,  combination of
shares,  exchange  of shares or other  change in  corporate  structure  effected
without the Company's receipt of consideration,  appropriate adjustments will be
made to (i) the maximum number and class of securities issuable under the Option
Plan, (ii) the maximum number and class of securities by which the share reserve
may  increase in any calendar  year by reason of the  automatic  share  increase
provisions of the Option Plan,  (iii) the maximum number and class of securities
for which any one  participant  may be  granted  stock  options  and  separately
exercisable stock appreciation rights over the term of the Option Plan, and (iv)
the number and class of  securities  and the exercise  price per share in effect
under each outstanding option.

Eligibility

Employees of the Company and its parent and  subsidiaries  (whether now existing
or subsequently established),  non-employee members of the Board or the board of
directors of any parent or subsidiary,  and  consultants  and other  independent
advisors  who provide  services  to the Company and its parent and  subsidiaries
(whether  now  existing  or  subsequently   established)  will  be  eligible  to
participate in the Option Plan.

As of March 15, 1999,  six (6) executive  officers,  four hundred  seventy-seven
(477) other employees,  and six (6) non-employee  Board members were eligible to
participate in the Option Plan.

Valuation

The fair market value per share of Common  Stock on any relevant  date under the
Option  Plan  will be the  closing  selling  price per share on that date on the
Nasdaq National  Market.  On March 15, 1999, the closing selling price per share
was $36.00.

                                  Option Grants

Price and Exercisability

Options may be granted under the Option Plan at an exercise  price per share not
less than eighty-five percent (85%) of the fair market value per share of Common
Stock on the option grant date. No granted  option will have a term in excess of
ten (10) years.  The options will  generally  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.  Vested
options may also be exercised  through a same-day sale program pursuant to which
a  designated  brokerage  firm  will  effect  an  immediate  sale of the  shares
purchased under the option and pay over to the Company, out of the sale proceeds
available on the settlement  date,  sufficient funds to cover the exercise price
for the purchased shares plus all applicable withholding taxes.

The shares of Common Stock acquired upon the exercise of one or more options may
be unvested and subject to repurchase by the Company,  at the original  exercise
price paid per share,  if the optionee  ceases service with the Company prior to
vesting in those shares. The Plan Administrator will have complete discretion to
establish the vesting  schedule to be in effect for any such unvested shares and
may at any time cancel the Company's outstanding  repurchase rights with respect
to those shares and thereby accelerate the vesting of those shares.

No optionee will have 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

                                       10



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  cessation of 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.  The Plan  Administrator  will have  complete
discretion to extend the period  following the  optionee's  cessation of service
during  which  his  or  her  outstanding  options  may be  exercised  and/or  to
accelerate  the  exercisability  or vesting of such options in whole or in part.
Such  discretion  may  be  exercised  at  any  time  while  the  options  remain
outstanding, whether before or after the optionee's actual cessation of service.

Stock Appreciation Rights

The Plan  Administrator  is authorized to issue two types of stock  appreciation
rights in connection with option grants made under the Option Plan:

         Tandem stock appreciation  rights provide the holders with the right to
         surrender  their  options  for an  appreciation  distribution  from the
         Company  equal in amount to the excess of (a) the fair market  value of
         the vested  shares of Common Stock  subject to the  surrendered  option
         over (b) the aggregate  exercise  price payable for those shares.  Such
         appreciation   distribution   may,  at  the   discretion  of  the  Plan
         Administrator,  be made in cash,  in shares of  Common  Stock,  or in a
         combination of cash and shares of Common Stock.

         Limited  stock  appreciation  rights  may be  provided  to one or  more
         officers or non-employee  Board members as part of their option grants.
         Any  option  with  such  a  limited  stock  appreciation  right  may be
         surrendered to the Company upon the successful  completion of a hostile
         tender  offer  for more  than  fifty  percent  (50%)  of the  Company's
         outstanding  voting stock.  In return for the surrendered  option,  the
         officer or Board  member will be entitled to a cash  distribution  from
         the  Company in an amount per  surrendered  option  share  equal to the
         excess of (a) the highest  price paid per share of Common Stock paid in
         connection  with the tender offer over (b) the exercise  price  payable
         for such share.

Cancellation/Regrant Program

The Plan  Administrator  will also have the authority to effect the cancellation
of  outstanding  options  under the Option  Plan which have  exercise  prices in
excess  of the then  current  market  price  of the  Common  Stock  and to issue
replacement  options with an exercise  price based on the lower  current  market
price of Common Stock at the time of the new grant.

On   August   21,   1998,   the  Plan   Administrator   implemented   an  option
cancellation/regrant  program  for  employees  of  the  Company,  excluding  the
Company's executive officers.  Pursuant to that program,  each such employee was
given the opportunity to surrender his or her outstanding options under the Plan
with  exercise  prices in excess of $12.00  per share in return for a new option
grant for the same  number of shares  but with an  exercise  price of $10.00 per
share,  the closing  selling  price per share of Common Stock as reported on the
Nasdaq  National  Market on the  August 21,  1998 grant date of the new  option.
Options for a total of 903,423 shares with a weighted  average exercise price of
$20.66 per share were surrendered for cancellation, and new options for the same
number of shares were granted with the $10.00 per share exercise  price.  To the
extent the  higher-priced  option was  exercisable  for any option shares on the
August 21, 1998 cancellation date, the new option granted in replacement of that
option will become exercisable for those shares upon the optionee's continuation
in service  through August 20, 1999. The option will become  exercisable for the
remaining  option  shares  in  a  series  of  quarterly  installments  over  the
optionee's  period  of  continued  service  with the  Company,  with  each  such
installment  to  become  exercisable  six (6)  months  later  than the date that
installment   was   scheduled  to  become   exercisable   under  the   cancelled
higher-priced option.

                                       11




                               General Provisions

Acceleration

In the  event  that the  Company  is  acquired  by merger  or asset  sale,  each
outstanding  option  under the Option  Plan,  to the  extent not  assumed by the
successor  corporation or replaced with a cash incentive program  preserving the
spread on the unvested option shares, will automatically accelerate in full, and
all unvested shares issued under the Option Plan will immediately  vest,  except
to the extent the Company's  repurchase  rights with respect to those shares are
to be assigned to the successor  corporation.  Any options assumed in connection
with such acquisition will immediately accelerate, and any unvested shares which
do not vest at the time of such acquisition will immediately  vest, in the event
the individual's  service with the successor  entity is subsequently  terminated
within a specified period  following the  acquisition.  In connection with other
changes in control of the Company  (whether by successful  tender offer for more
than fifty  percent  (50%) of the  outstanding  voting  stock or a change in the
majority of the Board as a result of one or more proxy contests for the election
of Board members), the Plan Administrator will have the discretionary  authority
to provide for automatic  acceleration of outstanding  options and the automatic
vesting of all unvested  shares  outstanding  under the Option  Plan,  with such
acceleration or vesting to occur either at the time of such change in control or
upon the subsequent termination of the individual's service.

The  acceleration  of vesting  upon a change in the  ownership or control of the
Company  may be seen as an  anti-takeover  provision  and may have the effect of
discouraging  a merger  proposal,  a takeover  attempt or other  efforts to gain
control of the Company.

Financial Assistance

The Plan  Administrator  may  institute  a loan  program  to assist  one or more
participants  in financing the exercise of outstanding  options under the Option
Plan.  The Plan  Administrator  will have  complete  discretion to determine the
terms of any such financial assistance. However, the maximum amount of financing
provided any  individual may not exceed the cash  consideration  payable for the
issued shares plus all  applicable  taxes.  Any such financing may be subject to
forgiveness  in whole or in part, at the  discretion of the Plan  Administrator,
over the participant's period of service.

Special Tax Election

The Plan  Administrator  may provide one or more  holders of options or unvested
shares  with the right to have the  Company  withhold  a portion  of the  shares
otherwise  issuable to such individuals in satisfaction of the withholding taxes
to which such  individuals may become subject in connection with the exercise of
those  options  or  the  vesting  of  those  shares.  Alternatively,   the  Plan
Administrator may allow such individuals to deliver  previously  acquired shares
of Common Stock in payment of such tax liability.

outstanding  under the Option Plan,  3,968,962  shares  remained  available  for
future  option  grant,  assuming  stockholder  approval  of the  3,500,000-share
increase  which  forms part of this  Proposal,  and  1,690,395  shares have been
issued under the Option Plan.

Amendment and Termination

The Board may amend or modify the Option Plan in any or all respects whatsoever,
subject to any required stockholder approval. The Board may terminate the Option
Plan at any time,  and the Option Plan will in all events  terminate on July 24,
2005.

                         Federal Income Tax Consequences

Option Grants

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 meet such  requirements.  The
Federal income tax treatment for the two types of options differs as follows:

                                       13




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
a taxable disposition.  For Federal tax purposes,  dispositions are divided into
two categories: (i) qualifying and (ii) disqualifying.  A qualifying disposition
occurs if the sale or other  disposition is made after the optionee has held the
shares for more than two (2) years after the option grant date and more than one
(1) year after the exercise date. If either of these two holding  periods is not
satisfied, then a disqualifying disposition 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, then
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 option exercise date over (ii) the exercise price paid for
the shares.  In no other  instance will the Company be allowed a deduction  with
respect to the optionee's disposition of the purchased shares.

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 paid for the shares,  and the optionee will be required to satisfy the tax
withholding requirements applicable to such income.

If the shares  acquired upon exercise of the  non-statutory  option are unvested
and  subject  to  repurchase  by the  Company  in the  event  of the  optionee's
termination of service prior to vesting in those shares,  then the optionee will
not recognize any taxable income at the time of exercise but will have to report
as ordinary income, as and when the Company's repurchase right lapses, an amount
equal to the excess of (i) the fair  market  value of the shares on the date the
repurchase  right lapses over (ii) the exercise  price paid for the shares.  The
optionee may, however, elect under Section 83(b) of the Internal Revenue Code to
include as ordinary income in the year of exercise of the option an amount equal
to the  excess  of (i) the fair  market  value of the  purchased  shares  on the
exercise date over (ii) the exercise price paid for such shares.  If the Section
83(b) election is made, the optionee will not recognize any additional income as
and when the repurchase right lapses.

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

Stock Appreciation Rights

An optionee who is granted a stock  appreciation  right will recognize  ordinary
income  in the  year  of  exercise  equal  to  the  amount  of the  appreciation
distribution.  The Company will be entitled to an income tax deduction  equal to
such  distribution  for the  taxable  year  in  which  the  ordinary  income  is
recognized by the optionee.

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  granted  with  exercise  prices equal to the fair market
value of the option  shares on the grant date 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 $1 million  maximum  limitation  per covered
individual on the  deductibility of the compensation  paid to certain  executive
officers of the Company.  Accordingly, all compensation deemed paid with respect
to those options will remain deductible by the Company without  limitation under
Code Section 162(m).



                                       14



                              Accounting Treatment

Option grants with exercise prices less than the fair market value of the shares
on the  grant  date will  result  in a  compensation  expense  to the  Company's
earnings equal to the difference  between the exercise price and the fair market
value of the shares on the grant date.  Such  expense  will be  accruable by the
Company over the period that the option  shares are to vest.  Option grants with
exercise  prices  equal to the fair market value of the shares on the grant date
will not result in any charge to the  Company's  earnings,  but the Company must
disclose, in footnotes to the Company's financial  statements,  the impact those
options would have upon the Company's  reported  earnings were the fair value of
those  options  treated as  compensation  expense.  Whether or not  granted at a
discount,  the number of outstanding  options may be a factor in determining the
Company's earnings per share on a fully-diluted basis.

The Financial  Accounting  Standards  Board recently  announced its intention to
issue an exposure draft of a proposed  interpretation of the current  accounting
principles  applicable to equity  incentive plans such as the Option Plan. Under
the proposed interpretation, option grants made to non-employee Board members or
consultants  after  December  15,  1998 will  result  in a direct  charge to the
Company's  reported  earnings  based upon the fair value of the option  measured
initially  as of the grant  date of that  option  and then  subsequently  on the
vesting  date  of each  installment  of the  underlying  option  shares.  If the
proposed  interpretation is adopted,  then such charge will accordingly  include
the  appreciation  in the value of the option shares over the period between the
grant  date of the  option  (or,  if  later,  the  effective  date of the  final
interpretation)  and the vesting date of each  installment of the option shares.
In addition,  if the proposed  interpretation is adopted,  any options which are
repriced  after  December  15,  1998  will also  trigger a direct  charge to the
Company's  reported  earnings  measured  by the  appreciation  in  value  of the
underlying  shares  between  the grant date of the  option  (or,  if later,  the
effective date of the final interpretation) and the date the option is exercised
for those shares.

Should one or more individuals be granted tandem stock appreciation rights under
the option plan,  then such rights would result in a compensation  expense to be
charged against the Company's reported earnings. Accordingly, at the end of each
fiscal quarter, the amount (if any) by which the fair market value of the shares
of common  stock  subject  to such  outstanding  stock  appreciation  rights has
increased from the prior quarter-end  would be accrued as compensation  expense,
to the extent  such fair  market  value is in excess of the  aggregate  exercise
price in effect for those rights.

                                New Plan Benefits

As of March 15,  1999,  no options have been granted to date on the basis of the
3,500,000-share increase to the Option Plan which forms part of this Proposal.

                              Stockholder Approval

The  affirmative  vote of a majority  of the  outstanding  voting  shares of the
Company  present or  represented  and entitled to vote at the Annual  Meeting is
required to approve the  amendment to the Option Plan.  Should such  stockholder
approval not be obtained, then any options granted on the basis of the 3,500,000
share increase which forms part of this Proposal will terminate without becoming
exercisable for any of the shares of Common Stock subject to those options,  and
no  further  options  will be made on the  basis  of  such  share  increase.  In
addition,  the automatic  annual share  increase  feature  pursuant to which the
number of shares  available for issuance under the Option Plan would increase on
the first trading day of January each  calendar  year,  beginning  with calendar
year 2002 and  continuing  over the  remaining  term of the Option  Plan,  by an
amount  equal to four and  thirty-six  hundredths  percent  (4.36%) of the total
number  of  shares  outstanding  on the  last  trading  day in  December  in the
immediately preceding calendar year will not be implemented. However, the Option
Plan will  continue to remain in effect,  and option  grants may  continue to be
made pursuant to the provisions of the Option Plan prior to the amendment  until
the available  reserve of Common Stock under the Option Plan as last approved by
the stockholders is issued.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE AMENDMENTS 
TO THE OPTION PLAN.

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

                                 PROPOSAL NO. 3:

                             APPROVAL OF AMENDMENTS
              TO THE 1995 NON-EMPLOYEE DIRECTORS STOCK OPTION PLAN
         --------------------------------------------------------------

The Company's  stockholders are being asked to approve a series of amendments to
the Company's  1995  Non-Employee  Directors  Stock Option Plan (the  "Directors
Plan") which will effect the following changes:

(i)               The maximum  number of shares of Common Stock  authorized  for
                  issuance over the term of the Directors Plan will be increased
                  by an additional 200,000 shares.

(ii)              An  automatic  share  increase  feature  will  be  implemented
                  pursuant to which the number of shares  available for issuance
                  under the Directors  Plan will  automatically  increase on the
                  first  trading day in January each  calendar  year,  beginning
                  with calendar year 2002 and continuing over the remaining term
                  of the Directors Plan, by an amount equal to two tenths of one
                  percent  (0.2%) of the total number of shares  outstanding  on
                  the last trading day in December in the immediately  preceding
                  calendar year,  but in no event will any such annual  increase
                  exceed 75,000 shares.

(iii)             Each  individual  who  is  first  elected  or  appointed  as a
                  non-employee   Board  member  at  or  after  the  1999  Annual
                  Stockholders  Meeting will  automatically  be granted,  on the
                  date of such initial election or appointment,  a non-statutory
                  stock  option to  purchase  32,000  shares  of  Common  Stock.
                  Previously,  newly  elected or  appointed  non-employee  Board
                  members  received an initial option grant for 16,000 shares of
                  Common Stock.

(iv)              On the date of each  Annual  Stockholders  Meeting,  beginning
                  with  the  1999  Annual  Meeting,  each  individual  who is to
                  continue  to  serve  as  a  non-employee   Board  member  will
                  automatically  be granted,  whether or not such  individual is
                  standing  for  re-election  as a Board  member at that  Annual
                  Meeting,   a   non-statutory   stock  option  to  purchase  an
                  additional  8,000  shares  of  Common  Stock,   provided  such
                  individual  has served as a  non-employee  Board member for at
                  least  six (6)  months  prior to the  date.  Previously,  such
                  annual  option  grants  were for only  4,000  shares of Common
                  Stock.

The  amendments  will  allow  the  Company  to  offer a more  meaningful  equity
compensation package in order to attract and retain highly-qualified individuals
to serve as non-employee Board members. The amendments were adopted by the Board
in  December 1998,  subject to  stockholder  approval  at the 1999  Annual
Meeting.

The  following is a summary of the  principal  features of the  Directors  Plan,
together with the applicable tax and accounting  implications,  which will be in
effect if the amendments to the Directors Plan are approved by the stockholders.
However,  the summary does not purport to be a complete  description  of all the
provisions of the Directors  Plan. Any  stockholder of the Company who wishes to
obtain a copy of the actual plan document may do so upon written  request to the
Secretary at the Company's principal executive offices in Sunnyvale, California.

The terms and  conditions of each automatic  option grant  (including the timing
and pricing of the option grant) are determined by the express provisions of the
Directors  Plan.  Neither the Board nor any  committee of the Board will perform
any discretionary  functions under the Directors Plan.  Stockholder  approval of
this Proposal  will also  constitute  approval of each option  granted under the
Directors Plan at or after the 1999 Annual  Meeting and the subsequent  exercise
of that option in accordance  with the terms of the Directors  Plan described in
this Proposal.


                                       16



Share Reserve

A total of 400,000  shares of Common Stock has been  reserved for issuance  over
the ten-year term of the Directors Plan,  including the  200,000-share  increase
which forms part of this Proposal.  In addition,  upon  stockholder  approval of
this Proposal,  the number of shares  available for issuance under the Directors
Plan will  automatically  increase  on the first  trading  day in  January  each
calendar  year,  beginning  with  calendar  year  2002 and  continuing  over the
remaining  term of the  Directors  Plan, by an amount equal to two tenths of one
percent (0.2%) of the total number of shares of Common Stock  outstanding on the
last trading day in December in the immediately  preceding calendar year, but in
no event will any such  annual  increase  exceed  75,000  shares.  The shares of
Common  Stock  issuable  under the  Directors  Plan may be made  available  from
authorized but unissued  shares of the Company's  Common Stock or from shares of
Common Stock  repurchased by the Company,  including  shares  repurchased on the
open market.

Should an option  expire or terminate  for any reason prior to exercise in full,
the shares  subject  to the  portion  of the  option  not so  exercised  will be
available  for  subsequent  issuance  under the  Directors  Plan.  In  addition,
unvested shares issued under the Directors Plan and subsequently  repurchased by
the  Company at the option  exercise  price paid per share will be added back to
the share  reserve and will  accordingly  be available for  subsequent  issuance
under the Directors Plan.  However,  shares subject to any option surrendered in
accordance with the option  surrender  provisions of the Directors Plan will not
be available for subsequent issuance.

Changes in Capitalization

In the event any  change is made to the  outstanding  shares of Common  Stock by
reason of any  recapitalization,  stock  dividend,  stock split,  combination of
shares,  exchange  of shares or other  change in  corporate  structure  effected
without the Company's receipt of consideration,  appropriate adjustments will be
made to (i) the  maximum  number  and  class of  securities  issuable  under the
Directors  Plan,  (ii) the maximum  number and class of  securities by which the
share reserve may increase in any calendar year by reason of the automatic share
increase  provisions  of the  Directors  Plan,  (iii)  the  number  and class of
securities for which option grants are  subsequently to be made to newly-elected
or  continuing  non-employee  Board  members  and (iv) the  number  and class of
securities  and the exercise  price per share in effect  under each  outstanding
option.

Eligibility

Only non-employee  Board members will be eligible to receive option grants under
the Directors  Plan. As of March 15, 1999,  six (6)  non-employee  Board members
were eligible to participate in the Directors Plan.

Valuation

The fair market value per share of Common  Stock on any relevant  date under the
Directors  Plan will be the closing  selling price per share on that date on the
Nasdaq National  Market.  On March 15, 1999, the closing selling price per share
was $36.00.

                                  Option Grants

Under the terms of the amended Directors Plan, each individual who first becomes
a non-employee Board member at or after the 1999 Annual Meeting, 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 32,000 shares of Common Stock, provided such individual
has not previously been in the Company's employ. In addition,  each non-employee
Board member who is to continue to serve on the Board will receive a 8,000-share
automatic  option  grant  on the  date  of  each  Annual  Stockholders  Meeting,
beginning with the 1999 Annual Meeting, provided such individual has served as a
non-employee Board member for at least six (6) months. There will be no limit on
the number of such  8,000-share  option grants that any one  non-employee  Board
member may receive  over his or her period of Board  service,  and  non-employee
Board  members who have been in the prior employ of the Company will be eligible
to receive one or more of those annual grants.

                                       17




Each  option  will have an  exercise  price per share  equal to 100% of the fair
market  value per share of Common Stock on the grant date.  The  exercise  price
will be payable in cash or in shares of Common Stock or through a same-day  sale
program with no cash outlay by the optionee. The option will have a maximum term
of ten (10) years measured from the grant date,  subject to earlier  termination
at the  end of the  twelve  (12)-month  period  measured  from  the  date of the
optionee's  cessation  of  Board  service.   Each  option  will  be  immediately
exercisable for any or all of the option shares.  However,  any shares purchased
under the option will be subject to repurchase  by the Company,  at the exercise
price paid per share,  upon the  optionee's  cessation of Board service prior to
vesting in those shares. The shares subject to each initial  32,000-share option
grant  will  vest in 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.  The  shares  subject  to each  annual
8,000-share option grant will vest in full upon the optionee's completion of one
(1) year of Board  service  measured  from the grant  date.  The  option  may 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.

Vesting Acceleration

The shares subject to each option will  immediately vest upon (i) the optionee's
death or permanent  disability while a Board member,  (ii) an acquisition of the
Company by merger or asset sale,  (iii) the  successful  completion  of a tender
offer for more than fifty  percent  (50%) of the  Company's  outstanding  voting
stock or (iv) a change in the majority of the Board effected through one or more
proxy contests for Board membership. In addition, upon the successful completion
of a hostile  tender offer for more than fifty  percent  (50%) of the  Company's
outstanding  voting  stock,  each  outstanding  automatic  option  grant  may be
surrendered to the Company for a cash distribution per surrendered  option share
in an amount  equal to the excess of (a) the  highest  price per share of Common
Stock paid in  connection  with such tender  offer over (b) the  exercise  price
payable for such share.  Stockholder  approval of this Proposal will  constitute
pre-approval of each such option surrender right subsequently  granted under the
Directors Plan and the subsequent  exercise of that right in accordance with the
terms of the Directors Plan.

The  acceleration  of vesting  upon a change in the  ownership or control of the
Company  may be seen as an  anti-takeover  provision  and may have the effect of
discouraging  a merger  proposal,  a takeover  attempt or other  efforts to gain
control of the Company.

Stock Awards

The table below shows, as to each of the Company's  non-employee  Board members,
the  number of shares of Common  Stock  subject  to  options  granted  under the
Directors Plan between the January 1, 1998 and March 15, 1999, together with the
weighted  average  exercise  price payable per share.  Only  non-employee  Board
members received option grants under the Directors Plan.

As of March 15,  1999  options  covering  124,000  shares of Common  Stock  were
outstanding  under the Directors  Plan,  276,000 shares  remained  available for
future option grant  (including the  200,000-share  increase which forms part of
this Proposal) and no shares have been issued under the Directors Plan.

(1) Mr. Rizzi resigned from the Board as of October 22, 1998.

Amendment and Termination

The Board may amend or modify the  provisions of the Directors Plan at any time.
Certain  amendments  to the  Directors  Plan may  require  stockholder  approval
pursuant  to  applicable  laws or  regulations.  The  Board  may  terminate  the
Directors Plan at any time, and the Directors Plan will in all events  terminate
on July 24, 2005.

                         Federal Income Tax Consequences

Options granted under the Directors Plan are all non-statutory options which are
not intended to satisfy the  requirements of Section 422 of the Internal Revenue
Code. The Federal income tax treatment for non-statutory options is as follows:

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 paid for the
shares.


                                       19



If the shares  acquired upon exercise of the  non-statutory  option are unvested
and  subject  to  repurchase  by the  Company  in the  event  of the  optionee's
termination of service prior to vesting in those shares,  then the optionee will
not recognize any taxable income at the time of exercise but will have to report
as ordinary income, as and when those shares vest, an amount equal to the excess
of (i) the fair  market  value of the  shares at time of  vesting  over (ii) the
exercise  price paid for those shares.  The optionee may,  however,  elect under
Section 83(b) of the Internal Revenue Code to include as ordinary income, in the
year in which the option is exercised,  an amount equal to the excess of (i) the
fair market value of the  purchased  shares on the  exercise  date over (ii) the
exercise price paid for such shares.  If the Section 83(b) election is made, the
optionee  will not  recognize  any  additional  income  as and  when the  shares
subsequently vest.

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

                              Accounting Treatment

Under current accounting principles, option grants to non-employee Board members
with  exercise  prices equal to the fair market value of the shares on the grant
date will not result in any charge to the  Company's  earnings,  but the Company
must disclose,  in footnotes to the Company's financial  statements,  the impact
those  options  would have upon the  Company's  reported  earnings were the fair
value of those  options at the time of grant  treated as  compensation  expense.
However,   under  a   recently-proposed   interpretation   of  those  accounting
principles,  option grants made to non-employee Board members after December 15,
1998 will result in a direct charge to the  Company's  reported  earnings  based
upon the fair value of the  option  measured  initially  as of the grant date of
that option and then subsequently on the vesting date of each installment of the
underlying option shares. If the proposed interpretation is adopted, such charge
will accordingly include the appreciation in the value of the option shares over
the period  between the grant date of the option (or,  if later,  the  effective
date of the final  interpretation)  and the vesting date of each  installment of
the  option  shares.  Whether  or not  granted  at a  discount,  the  number  of
outstanding  options may be a factor in determining  the Company's  earnings per
share on a fully-diluted basis.
                                New Plan Benefits

No option  grants have been made on the basis of the  200,000-share  increase to
the  Directors  Plan  which  forms  part of this  Proposal.  At the 1999  Annual
Meeting,  each of the following  non-employee Board members who will continue to
serve in such capacity will automatically be granted an option to purchase 8,000
shares of Common  Stock at an  exercise  price  per share  equal to the  closing
selling  price per share of Common Stock on that grant date:  Messrs:  Federman,
Campbell, Meindl, Mulvaney, Shugart and Ms. Lego.

                              Stockholder Approval

The  affirmative  vote of a majority  of the  outstanding  voting  shares of the
Company  present or  represented  and entitled to vote at the Annual  Meeting is
required  to  approve  the  amendments  to  the  Directors  Plan.   Should  such
stockholder approval not be obtained,  then none of the changes to the Directors
Plan will be implemented.  Accordingly,  each of the non-employee  Board members
who are re-elected at the 1999 Annual  Meeting will receive an automatic  option
grant for 4,000  shares at that  meeting,  and the newly  elected  or  appointed
non-employee  Board  members will each receive an option grant for 16,000 shares
at the time they first join the Board. In addition,  the share reserve under the
Directors Plan will remain limited to 200,000 shares.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE AMENDMENTS 
TO THE DIRECTORS PLAN.

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

                                 PROPOSAL NO. 4:

                              APPROVAL OF AMENDMENT
                       TO THE EMPLOYEE STOCK PURCHASE PLAN
                 -----------------------------------------------

The  Company's  stockholders  are being  asked to  approve an  amendment  to the
Company's  Employee  Stock  Purchase  Plan (the  "Purchase  Plan") that will (i)
increase the maximum  number of shares of Common Stock  authorized  for issuance
over the term of the Purchase Plan by an additional 300,000 shares to a total of
1,183,333 shares and (ii) implement an automatic share increase feature pursuant
to which the number of shares  available  for issuance  under the Purchase  Plan
will  automatically  increase on the first  trading day in January each calendar
year,  beginning with calendar year 2002 and continuing  over the remaining term
of the  Purchase  Plan,  by an amount  equal to  forty-three  hundredths  of one
percent  (0.43%) of the total number of shares  outstanding  on the last trading
day in December in the immediately preceding calendar year, but in no event will
any such annual increase  exceed 150,000  shares.  The amendment to the Purchase
Plan was  adopted  by the  Board of  Directors  in  December  1998,  subject  to
stockholder approval at the 1999 Annual Meeting.

The  amendment  will allow the Company to maintain a  sufficient  share  reserve
under the  Purchase  Plan so that  eligible  employees  of the  Company  and its
participating  affiliates  will continue to have the  opportunity  to acquire an
equity  interest in the Company and thereby  further align their  interests with
those of the stockholders.

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

Administration

The Purchase Plan is  administered by the  Compensation  Committee of 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 plan  administration  are paid
by the Company without charge to participants.

Securities Subject to the Purchase Plan

If the  300,000-share  increase which forms part of this Proposal is approved at
the Annual Meeting, then the total number of shares of Common Stock reserved for
issuance in the  aggregate  over the term of the Purchase Plan and the Company's
International Employee Stock Purchase Plan, a comparable stock purchase plan for
employees of the Company's foreign subsidiaries who are not residing in the U.S.
(the "International Plan"), will be increased to 1,183,333 shares.  Accordingly,
stockholder  approval  of this  Proposal  will also result in an increase to the
number of shares of Common Stock issuable under the International  Plan, subject
to the aggregate  limitation of 1,183,333  issuable shares over the term of this
Plan and the International Plan. In addition,  upon stockholder approval of this
Proposal, the number of shares available for issuance under the combined reserve
under the Purchase Plan and the International Plan will  automatically  increase
on the first trading day in January each calendar year,  beginning with calendar
year 2002 and  continuing  over the remaining  term of the Purchase  Plan, by an
amount  equal to  forty-three  hundredths  of one  percent  (0.43%) of the total
number of shares of Common Stock outstanding on the last trading day in December
in the immediately preceding calendar year, but in no event will any such annual
increase exceed 150,000 shares. The shares may be made available from authorized
but unissued shares of the Company's Common Stock or from shares of Common Stock
repurchased by the Company, including shares repurchased on the open market.

In the event that any change is made to the Company's  outstanding  Common Stock
(whether  by  reason  of any  recapitalization,  stock  dividend,  stock  split,
exchange  or  combination  of shares  or other  change  in  corporate  structure
effected   without  the  Company's   receipt  of   consideration),   appropriate
adjustments  will be made to (i) the class  and  maximum  number  of  securities
issuable  in  the  aggregate  over  the  term  of  the  Purchase  Plan  and  the
International Plan, (ii) the maximum number and class of

                                       21



securities  by which the combined  share  reserve  under the  Purchase  Plan and
International  Plan may increase in any calendar year by reason of the automatic
share  increase  provisions  of the Purchase  Plan,  (iii) the class and maximum
number of securities purchasable per participant on any one semi-annual purchase
date and (iv) the class  and  number  of  securities  and the price per share in
effect under each outstanding purchase right.

Purchase Periods and Purchase Rights

Shares of Common Stock are offered  under the Purchase  Plan through a series of
successive  offering periods.  Each such offering period will have a duration of
six (6) months.  The offering  periods  will start on the first  business day in
February and August each year, and each such offering  period will have a single
purchase  date that  coincides  with the last business day of that six (6)-month
offering period.  For example,  the current offering period began on February 1,
1999 and will end on July 30,  1999.  That  latter date will also be the date on
which the shares for the current offering period will be purchased.

Eligibility and Participation

Any  individual  who is employed  on a basis under which he or she is  regularly
expected to work for 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.

Only  individuals who are eligible  employees at the start of an offering period
may join that offering  period.  At the time the participant  joins the offering
period,  he or she will be granted a purchase  right to acquire shares of Common
Stock on the purchase date for that offering  period.  Purchase dates will occur
on the  last  business  day in  January  and July  each  year,  and all  payroll
deductions  collected from the  participant for the period ending with each such
purchase date will automatically be applied to the purchase of Common Stock.

As of March 15, 1999, the Company  estimated that  approximately  474 employees,
including 5 executive  officers,  were eligible to  participate  in the Purchase
Plan.

Purchase Price

The purchase  price of the Common Stock  acquired on each  semi-annual  purchase
date will be equal to 85% of the lower of (i) the fair market value per share of
Common  Stock on the start date of the  offering  period or (ii) the fair market
value on that purchase date.

The fair market value per share of Common Stock on any particular date under the
Purchase Plan will be deemed to be equal to the closing  selling price per share
on such date on the Nasdaq  National  Market.  On March 15,  1999,  the  closing
selling  price per share of  Common  Stock on the  Nasdaq  National  Market  was
$36.00.

Payroll Deductions and Stock Purchases

Each participant may authorize periodic payroll deductions in any multiple of 1%
(up to a  maximum  of 10%) of his or her cash  compensation  (base  salary  plus
bonus,  overtime and  commissions)  to be applied to the  acquisition  of Common
Stock at semi-annual intervals.  Accordingly,  on each semi-annual purchase date
(the last business day in January and July each year),  the accumulated  payroll
deductions of each participant will  automatically be applied to the purchase of
whole shares of Common Stock at the purchase price in effect for the participant
for that purchase date.


                                       22



Special Limitations

The Purchase Plan imposes certain  limitations  upon a  participant's  rights to
acquire Common Stock, including the following limitations:
      -       Purchase  rights  granted to a  participant  may not  permit  such
              individual  to purchase  more than  $25,000  worth of Common Stock
              (valued  at the time  each  purchase  right is  granted)  for each
              calendar year those purchase rights are outstanding at any time.

      -       Purchase  rights  may not be  granted  to any  individual  if such
              individual  would,  immediately  after  the  grant,  own  or  hold
              outstanding options or other rights to purchase,  stock possessing
              five  percent (5%) or more of the total  combined  voting power or
              value  of  all  classes  of  stock  of the  Company  or any of its
              affiliates.

      -       No  participant  may purchase more than 750 shares of Common Stock
              on any one purchase  date.  However,  the Plan  Administrator  may
              increase or decrease  this per  participant  limit as of the start
              date of any new offering period under the Purchase Plan.

Termination of Purchase Rights

The  participant may withdraw from the Purchase Plan at any time, and his or her
accumulated  payroll deductions will, at the participant's  election,  either be
applied  to the  purchase  of shares on the next  semi-annual  purchase  date or
refunded.

The  participant's  purchase  right will  immediately  terminate upon his or her
cessation  of  employment  or loss of  eligible  employee  status.  Any  payroll
deductions  which the participant  may have made for the  semi-annual  period in
which  such  cessation  of  employment  or loss of  eligibility  occurs  will be
refunded and will not be applied to the purchase of Common Stock.

Stockholder Rights

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

Assignability

No purchase rights will be assignable or transferable  by the  participant,  and
the purchase rights will be exercisable only by the participant.

Change in Control

In the event the Company is acquired  by merger or asset sale,  all  outstanding
purchase  rights  will  automatically  be  exercised  immediately  prior  to the
effective date of such  acquisition.  The purchase price will be equal to 85% of
the lower of (i) the fair  market  value per share of Common  Stock on the start
date of the offering  period in which such  acquisition  occurs or (ii) the fair
market value per share of Common Stock immediately prior to such acquisition

Share Pro-Ration

Should the total number of shares of Common  Stock to be  purchased  pursuant to
outstanding  purchase  rights on any particular date exceed the number of shares
then available for issuance under the Purchase Plan, then the Plan Administrator
will make a  pro-rata  allocation  of the  available  shares  on a  uniform  and
nondiscriminatory basis, and the payroll deductions of each participant,  to the
extent in excess of the  aggregate  purchase  price payable for the Common Stock
pro-rated to such individual, will be refunded.


                                       23



Amendment and Termination

The Purchase Plan will  terminate upon the earliest of (i) the last business day
in July,  2005,  (ii)  the  date on which  all  shares  available  for  issuance
thereunder are sold pursuant to exercised  purchase  rights or (iii) the date on
which all purchase rights are exercised in connection with an acquisition of the
Company.

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
requirements for eligibility to participate 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 of the  offering  period in which such shares are
acquired,  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 the start  date of the  offering  period  in which the  shares  are
acquired,  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;
and 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

The  issuance  of Common  Stock  under the  Purchase  Plan will not  result in a
compensation   expense  chargeable  against  the  Company's  reported  earnings.
However,  the Company must  disclose,  in pro-forma  statements to the Company's
financial statements,  the impact 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.

Purchase Plan, and 741,455 shares were available for future  issuance,  assuming
stockholder  approval  of the  300,000-share  increase  which forms part of this
Proposal.


                                New Plan Benefits

As of March  15,  1999,  no  shares  have  been  purchased  on the  basis of the
300,000-share increase to the Purchase Plan.

                              Stockholder Approval

The  affirmative  vote of a majority  of the  outstanding  voting  shares of the
Company  present or  represented  and entitled to vote at the Annual  Meeting is
required  to approve  the share  increase  to the  Purchase  Plan.  Should  such
stockholder  approval  not be  obtained,  then the  maximum  number of shares of
Common Stock that may be issued over the term of the  Purchase  Plan will remain
at the level of 883,333 shares,  and the automatic share increase feature to the
Purchase Plan will not be implemented.  However, the Purchase Plan will continue
to remain in effect, and stock purchases may continue to be made pursuant to the
provisions  of the  Purchase  Plan until the  available  reserve of Common Stock
under the Purchase Plan is issued.

THE BOARD OF DIRECTORS  RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE AMENDMENTS
TO THE PURCHASE PLAN.

                                 PROPOSAL NO. 5:

                 RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS
            ---------------------------------------------------------

The Company is asking the  stockholders to ratify the selection of Ernst & Young
LLP as the Company's  independent  public accountants 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  Audit
Committee  of the Board of Directors  will  consider it as a direction to select
other auditors for the subsequent  year. Even if the selection is ratified,  the
Board of Directors in its discretion  may direct the  appointment of a different
independent  accounting  firm  at any  time  during  the  year if the  Board  of
Directors  determines  that such a change  would be in the best  interest of the
Company and its stockholders.

Ernst & Young LLP has audited the Company's financial  statements annually since
1991. Its representatives 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.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE PROPOSAL TO
RATIFY THE SELECTION OF ERNST & YOUNG LLP TO SERVE AS THE COMPANY'S  INDEPENDENT
PUBLIC ACCOUNTANTS FOR THE FISCAL YEAR ENDING JANUARY 2, 2000.

(1)    Except as  indicated  in the  footnotes  to this  table and  pursuant  to
       applicable  community  property laws, the persons named in the table have
       sole  voting and  investment  power with  respect to all shares of Common
       Stock. The number of shares  beneficially  owned includes Common Stock of
       which  such  individual  has the right to  acquire  beneficial  ownership
       either currently or within 60 days after March 15, 1999,  including,  but
       not limited to, upon the exercise of an option.

(2)    Percentage of  beneficial  ownership is based upon  26,819,100  shares of
       Common Stock,  all of which were  outstanding on March 15, 1999. For each
       individual,   this  percentage   includes  Common  Stock  of  which  such
       individual has the right to acquire beneficial ownership either currently
       or within 60 days after March 15,  1999,  including,  but not limited to,
       upon the exercise of

                                       27



       an option;  however, such Common Stock will not be deemed outstanding for
       the purpose of computing the  percentage  owned by any other  individual.
       Such  calculation  is required by General Rule  13d-3(d)(1)(i)  under the
       Securities  Exchange Act of 1934. Based upon a review of 13G filings made
       with the Securities and Exchange  Commission during 1998, the table above
       includes all greater than 5% stockholders.

(3)    Based on a Schedule 13G filed with the SEC in February 1999.

(4)    Includes  12,000 shares owned by Mr.  Campbell in the form of immediately
       exercisable  options,  some of which,  if exercised and issued,  would be
       subject to a repurchase right of the Company that lapses over time.

(5)    Includes  28,000 shares owned by Mr.  Federman in the form of immediately
       exercisable  options,  some of which,  if exercised and issued,  would be
       subject to a repurchase right of the Company that lapses over time.

(6)    Includes  12,000  shares  owned by Ms.  Lego in the  form of  immediately

(1)  Each option will become  exercisable  for 25% of the option shares upon the
     optionee's  completion  of one year of service  measured  from December 15,
     1998, the vesting commencement date, and the option will become exercisable
     for  the  remaining  shares  in a  series  of  successive  equal  quarterly
     installments  upon  the  optionee's  completion  of each  additional  three
     (3)-month  period of service  with the  Company  over the  36-month  period
     beginning December 15, 1999 and ending December 14, 2002.

(2)  The option will become  exercisable  for 25% of the option  shares upon Mr.
     Hudson's completion of one year of service measured from September 9, 1998,
     the vesting  commencement  date, and the option will become exercisable for
     the remaining shares in a series of successive equal quarterly installments
     upon his completion of each additional  three  (3)-month  period of service
     with the Company over the 36-month period  beginning  September 9, 1999 and
     ending September 8, 2002.

(3)  Each option will become  immediately  exercisable for all the option shares
     upon an  acquisition  of the  Company by merger or asset  sale,  unless the
     option is assumed by the acquiring  entity.  Each option has a maximum term
     of ten (10)  years,  subject  to  earlier  termination  in the event of the
     optionee's  cessation of service with the Company.  Each option  includes a
     limited stock  appreciation  right that will allow the  optionee,  upon the
     acquisition  of 25% or  more  of the  Company's  outstanding  voting  stock
     pursuant  to a  hostile  tender  offer,  to  surrender  that  option to the
     Company,  to the extent the  option is at the time  exercisable  for vested
     shares,  in  exchange  for a cash  distribution  based on the tender  offer
     price.

(4)  The Company granted options to purchase 2,182,058 shares of Common Stock to
     employees  during  1998.  Options for 903,423 of those  shares  represented
     options issued in replacment of higher-price options for the same number of
     shares which were cancelled as part of the August 1998 cancellation/regrant
     program.

(5)  The exercise price may be paid in cash or in shares of the Company's Common
     Stock  valued at fair market value on the  exercise  date.  The Company may
     finance the option exercise by loaning the optionee sufficient funds to pay
     the exercise price for the purchased shares,  together with any federal and
     state income tax liability incurred by the optionee in connection with such
     exercise.

(6)  Potential gains are net of exercise price, but before taxes associated with
     exercise.  There is no assurance  that the actual stock price  appreciation
     over the  10-year  option  term will be at the assumed 5% and 10% levels of
     assumed annual rates of compounded stock price appreciation 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.

         REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

The  Compensation  Committee  of the  Board  of  Directors  is  responsible  for
establishing the base salary and incentive cash bonus programs for the Company's
executive  officers and other key  employees  and  administering  certain  other
compensation  programs for such individuals,  subject in each instance to review
by  the  full  Board.  The   Compensation   Committee  also  has  the  exclusive
responsibility  for the  administration  of the Company's 1995 Stock Option Plan
under which  grants may be made to executive  officers and other key  employees.
The  Compensation  Committee is comprised of three  non-employee  Board members,
William V. Campbell and Alan F. Shugart.

GENERAL COMPENSATION POLICY. The overall policy of the Compensation Committee is
to  provide  the  Company's  executive  officers  and other key  employees  with
competitive  compensation  opportunities  based upon their  contribution  to the
financial  success of the  Company  and their  personal  performance.  It is the
Compensation  Committee's  objective  to  have a  substantial  portion  of  each
officer's compensation contingent upon the Company's performance as well as upon
the officer's own level of performance.  Accordingly,  the compensation  package
for each executive officer and key employee is comprised of three elements:  (i)
base salary which reflects  individual  performance and is designed primarily to
be competitive  with salary levels in effect at companies within and outside the
industry  with which the Company  competes  for  executive  talent,  (ii) annual
variable   performance  awards  payable  in  cash  and  tied  to  the  Company's
achievement of financial and individual performance targets, and (iii) long-term
stock-based incentive awards which strengthen the mutuality of interests between
the executive officers and the Company's stockholders. As an executive officer's
level  of  responsibility  increases,  it is  the  intent  of  the  Compensation
Committee  to  have  a  greater   portion  of  the  executive   officer's  total
compensation be dependent upon Company  performance and stock price appreciation
rather than base salary.

Factors.  The principal factors which the Compensation  Committee  considered in
establishing the components of each executive officer's compensation package for
the 1998 fiscal year are  summarized  below.  The  Compensation  Committee  may,
however,  at its  discretion  apply  entirely  different  factors,  particularly
different measures of financial  performance,  in setting executive compensation
for future fiscal years.

* Base Salary. For comparative  compensation  purposes for the 1998 fiscal year,
the  Compensation  Committee  selected  a peer  group of  companies  within  the
industry  which are  comparable in size and growth  pattern with the Company and
which  compete with the Company for executive  talent.  The base salary for each
officer was then  determined on the basis of the following  factors:  the salary
levels  in  effect  for  comparable   positions  at  the  peer  group  companies
(determined  on the  basis  of their  published  1997  fiscal  year  data),  the
experience and personal  performance  of the officer and internal  comparability
considerations.  The  weight  given  to  each of  these  factors  differed  from
individual to individual, as the Compensation Committee deemed appropriate.  The
compensation level for the Company's executive officers for the 1998 fiscal year
ranged from the 50th percentile to the 75th percentile of the base salary levels
in effect for  executive  officers with  comparable  positions at the peer group
companies, based on the published 1997 fiscal year data for those companies.

In  selecting   companies  to  survey  for  such  compensation   purposes,   the
Compensation  Committee  considered  many factors not directly  associated  with
stock  price  performance,  such  as  geographic  location,  development  stage,
organizational  structure and market  capitalization.  For this reason, there is
not a meaningful  correlation  between the  companies  included  within the peer
group  identified  for  comparative  compensation  purposes  and  the  companies
included  within the S&P Electronics  Semiconductor  Index which the Company has
selected  as the  industry  index for  purposes of the stock  performance  graph
appearing later in this Proxy Statement.

* Annual  Incentive  Compensation.  Annual  bonuses are earned by each executive
officer on the basis of the Company's achievement of certain corporate financial
performance  targets  established for the fiscal year and the individual's level
of  performance.  For fiscal year 1998, a minimum of 75% of the bonus target was
measured  on the basis of Company  performance  and the  remainder  of the bonus
target was tied to individual  performance.  Company performance was measured on
the basis of pre-tax  profit  (exclusive of royalties)  and net revenue  targets
established by the Compensation  Committee at the start of the 1998 fiscal year.
Because  these  targets were not met for the year,  no executive  officers  were
awarded  bonuses  for  fiscal  1998 on this basis as  indicated  for them in the
Summary  Compensation  Table  which  appears  earlier in this  proxy  statement.
However, Mr. Hudson was paid a one-time hiring bonus in 1998 as indicated in the
Summary Compensation Table which appears earlier in this proxy statement.


                                       33



* Long-Term Incentive  Compensation.  Long-term  incentives are provided through
stock  option  grants.  The grants are  designed to align the  interests of each
executive  officer with those of the  stockholders  and provide each  individual
with a significant  incentive to manage the Company from the  perspective  of an
owner with an equity stake in the business.  Each grant allows the individual to
acquire  shares of the  Company's  common  stock at a fixed price per share (the
market  price on the  grant  date)  over a  specified  period  of time (up to 10
years).  Each option  generally  becomes  exercisable in  installments  over the
executive  officer's  continued  employment with the Company.  Accordingly,  the
option will  provide a return to the  executive  officer  only if the  executive
officer  remains  employed by the Company during the applicable  vesting period,
and then only if the market price of the underlying shares  appreciates over the
option term.

The number of shares  subject to each option grant is set at a level intended to
create a  meaningful  opportunity  for stock  ownership  based on the  officer's
current  position  with the  Company,  the  size of  comparable  awards  made to
individuals in similar positions within the industry, the individual's potential
for  increased  responsibility  and  promotion  over the  option  term,  and the
individual's personal performance in recent periods. The Compensation  Committee
also takes into  account the number of unvested  options  held by the  executive
officer in order to maintain an appropriate  level of equity  incentive for that
individual.  However, the Compensation Committee does not adhere to any specific
guidelines  as to  the  relative  option  holdings  of the  Company's  executive
officers.

CEO COMPENSATION. In setting Dr. Harari's base salary as Chief Executive Officer
for the 1998  fiscal  year,  the  Compensation  Committee  sought to achieve two
objectives:  (i) establish a level of base salary  competitive with that paid to
other  chief  executive  officers  of the peer group  companies  and (ii) make a
significant percentage of the total compensation package contingent upon Company
performance.  The base  salary  established  for Dr.  Harari on the basis of the
foregoing  criteria was  intended to provide him with a level of  stability  and
certainty each year. Accordingly,  this element of Dr. Harari's compensation was
not affected to any significant degree by Company performance factors and was at
the 50th  percentile  of the base  salary  levels  in  effect  for  other  chief
executive  officers at the same peer group of companies surveyed for comparative
compensation  purposes.  The remaining  components of the compensation earned by
Dr.  Harari for the 1998  fiscal year were  entirely  dependent  upon  financial
performance  and  provided no dollar  guarantees.  No cash bonus was paid to Dr.
Harari  for the 1998  fiscal  year,  because  the  Company  failed to attain the
pre-tax profit and net revenue targets established by the Compensation Committee
for that year.

A stock option for an additional  100,000  shares of Common Stock was granted to
Dr.  Harari on December  15, 1998 in order to bring his level of unvested  stock
option  holdings to a level the  Compensation  Committee  deemed  appropriate to
provide him with a meaningful  incentive to remain in the  Company's  employ and
contribute  to the  financial  success of the Company in the form of stock price
appreciation.

COMPLIANCE  WITH INTERNAL  REVENUE CODE SECTION  162(M).  Section  162(m) of the
Internal Revenue Code, enacted in 1993,  generally  disallows a tax deduction to
publicly-held  companies for compensation paid to certain executive officers, to
the extent that  compensation  exceeds $1 million  per officer in any year.  The
compensation paid to the Company's  executive  officers for the 1998 fiscal year
did not exceed the $1 million  limit per  officer,  and it is not  expected  the
compensation to be paid to the Company's  executive officers for the 1999 fiscal
year will exceed that limit.  In addition,  the Company's 1995 Stock Option Plan
is structured so that any  compensation  deemed paid to an executive  officer in
connection  with the exercise of his or her  outstanding  options under the 1995
Plan with an exercise  price per share equal to the fair market  value per share
of the  Common  Stock  on the  grant  date  will  qualify  as  performance-based
compensation which will not be subject to the $1 million limitation.  Because it
is very  unlikely  that the cash  compensation  payable to any of the  Company's
executive officers in the foreseeable future will approach the $1 million limit,
the Compensation Committee has decided at this time not to take any other action
to limit  or  restructure  the  elements  of cash  compensation  payable  to the
Company's  executive officers.  The Compensation  Committee will reconsider this
decision  should the  individual  compensation  of any  executive  officer  ever
approach the $1 million level.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The  Compensation  Committee of the  Company's  Board of Directors was formed in
June 1990 and is comprised of Messrs.  William V.  Campbell and Alan F. Shugart.
Neither of these individuals was at any time during fiscal 1998, or at any other
time, an officer or employee of the Company. No executive officer of the Company
serves as a member of the board of  directors or  compensation  committee of any
other entity that has one or more executive  officers serving as a member of the
Company's Board of Directors or Compensation Committee.

                 EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT
                        AND CHANGE-IN-CONTROL AGREEMENTS

None of the Company's  executive  officers have  employment  agreements with the
Company, and their employment may be terminated at any time at the discretion of
the Board of  Directors.  Pursuant to the express  provisions  of the 1995 Stock
Option  Plan,  the  outstanding  options  under  the 1995 Plan held by the Chief
Executive  Officer and the Company's other executive  officers will  immediately
accelerate in full, and all unvested  shares of Common Stock at the time held by
such individuals  under the 1995 Plan will immediately  vest, in the event their
employment  were to be  terminated  (whether  involuntarily  or through a forced
resignation)  within twelve (12) months after any  acquisition of the Company by
merger or asset sale in which those options and shares did not  otherwise  vest.
In  addition,  the  Compensation  Committee  of the Board of  Directors  has the
authority as Plan Administrator of the 1995 Stock Option Plan to provide for the
accelerated  vesting of the outstanding  options under the 1995 Plan held by the
Chief  Executive  Officer and the  Company's  other  executive  officers and the
immediate  vesting of all  unvested  shares of Common  Stock at the time held by
such  individuals  under the 1995 Plan, in the event their employment were to be
terminated (whether  involuntarily or through a forced resignation)  following a
successful  tender  offer for more than  fifty  percent  (50%) of the  Company's
outstanding Common Stock or a change in the majority of the Board as a result of
one or more contested elections for Board membership.

                                PERFORMANCE GRAPH

The following  graph compares the  cumulative  total  stockholder  return on the
Common Stock of the Company with that of the Standard & Poors 500 Stock Index, a
broad    market    index    published    by   S&P,    and   a    selected    S&P
Electronics/Semiconductor  company  stock  index  compiled  by Morgan  Stanley &
Company.  The comparison for each of the periods  assumes that $100 was invested
on November 7, 1995 (the date of the Company's  initial public  offering) in the
Company's  Common Stock,  the stocks included in the S&P 500 Stock Index and the
stocks  included  in the  S&P  Electronics/Semiconductor  company  index.  These
indices,  which  reflect  formulas  for  dividend  reinvestment  and weighing of
individual stocks, do not necessarily  reflect returns that could be achieved by
individual investor

                              CERTAIN TRANSACTIONS

The  Company  has  a  strategic  relationship  with  Seagate  Technology,   Inc.
("Seagate"),  which owns 23.5% of the Company's  Common Stock as calculated on a
fully diluted basis. In January 1993,  Seagate acquired a 25% ownership interest
in the Company.  Seagate has the right to nominate one director to the Company's
Board of Directors. Thomas F. Mulvaney, Seagate's Senior Vice President, General
Counsel and  Secretary,  serves as Seagate's  nominee to the Company's  Board of
Directors.  The  Shareholder  Rights Plan,  adopted by the Board of Directors on
April 21, 1997,  permits  Seagate to continue to hold its ownership  interest in
the Company without triggering the provisions of the plan.

The Company intends that all future  transactions,  including loans, between the
Company and its officers, directors, principal stockholders and their affiliates
be approved by a majority of the Board of Directors, including a majority of the
independent and disinterested  outside directors on the Board of Directors,  and
be on terms no less  favorable  to the  Company  than  could  be  obtained  from
unaffiliated  third  parties.   In  addition,   the  Company  has  entered  into
indemnification agreements with each of its directors and executive officers.

                                 OTHER BUSINESS

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.

                              STOCKHOLDER PROPOSALS

Proposals of  stockholders  that are  intended to be presented at the  Company's
Annual Meeting of  stockholders  to be held in 2000 must be received by December
13, 1999 in order to be included in the proxy  statement  and proxy  relating to
that meeting.

In  addition,  the proxy  solicited  by the Board of  Directors  for the  Annual
Meeting to be held in 2000 will confer  discretionary  authority  to vote on any
stockholder  proposal presented at that meeting,  unless the Company is provided
with notice of such proposal no later than February 24, 2000.
