               Information Required in the Registration Statement



Item 3.  Incorporation of Documents by Reference

         SanDisk Corporation (the "Registrant") hereby incorporates by reference
into this Registration  Statement the following documents  previously filed with
the Securities and Exchange Commission (the "SEC"):

   (a)The  Registrant's  Annual  Report on Form 10-K for the  fiscal  year ended
      December 31, 1996 filed with the SEC on March 13, 1997;

   (b)The Registrant's Quarterly Report on Form 10-Q for the quarter ended March
      31, 1997, filed with the SEC on May 14, 1997;

   (c)The  Registrant's  Current Report on Form 8-K, filed with the SEC on April
      28, 1997, as amended on May 16, 1997; and

   (d)The  Registrant's  Registration  Statement  No.  0-26734 on Form 8-A filed
      with  the  SEC  on  September  8,  1995,  pursuant  to  Section  12 of the
      Securities  Exchange Act of 1934,  as amended  (the "1934 Act"),  together
      with the amendments thereto, in which there is described the terms, rights
      and provisions applicable to the Registrant's outstanding Common Stock.

         All  reports  and  definitive  proxy or  information  statements  filed
pursuant to Section 13(a),  13(c), 14 or 15(d) of the 1934 Act after the date of
this  Registration  Statement  and  prior  to  the  filing  of a  post-effective
amendment which  indicates that all securities  offered hereby have been sold or
which  deregisters  all securities  then remaining  unsold shall be deemed to be
incorporated  by reference  into this  Registration  Statement  and to be a part
hereof from the date of filing of such documents.


Item 4.  Description of Securities

         Not Applicable.


Item 5.  Interests of Named Experts and Counsel

         Not Applicable.


Item 6.  Indemnification of Directors and Officers

         Section 145 of the Delaware General  Corporation Law authorizes a court
to award or a  corporation's  Board of  Directors  to grant  indemnification  to
directors   and   officers   in  terms   sufficiently   broad  to  permit   such
indemnification   under  certain   circumstances   for  liabilities   (including
reimbursement  for expenses  incurred) arising under the Securities Act of 1933,
as amended (the "1933 Act").  The  Registrant's  Bylaws provide for  permissible
indemnification of employees and other agents to the maximum extent permitted by
the  Delaware  General   Corporation   Law.  The  Registrant's   Certificate  of
Incorporation  provides that,  pursuant to Delaware law, its directors

                                      II-1
<PAGE>

shall not be liable for monetary  damages for breach of their  fiduciary duty as
directors  to  the  Registrant  and  its  stockholders.  This  provision  in the
Certificate  of  Incorporation  does not  eliminate  the  fiduciary  duty of the
directors,   and  in  appropriate   circumstances  equitable  remedies  such  as
injunctive or other forms of  non-monetary  relief will remain  available  under
Delaware  law.  In  addition,  each  director  will  continue  to be  subject to
liability for breach of the  director's  duty of loyalty to the  Registrant  for
acts or omissions  not in good faith or involving  intentional  misconduct,  for
knowing  violations  of law,  for  payment of  dividends  or  approval  of stock
repurchases or redemptions  that are unlawful under Delaware law and for actions
leading to improper  personal  benefit to the director.  The provision also does
not  affect a  director's  responsibilities  under  any other  law,  such as the
federal securities laws or state or federal  environmental  laws. The Registrant
has entered into Indemnification Agreements with its officers and director which
provide such officers and directors with further  indemnification to the maximum
extent permitted by the Delaware General Corporation Law.


Item 7.  Exemption from Registration Claimed

         Not Applicable.

Item 9.  Undertakings

         A. The undersigned  Registrant hereby  undertakes:  (1) to file, during
any period in which offers or sales are being made, a  post-effective  amendment
to this Registration Statement (i) to include any prospectus required by Section
10(a)(3) of the 1933 Act, (ii) to reflect in the  prospectus any facts or events
arising after the  effective  date of this  Registration  Statement (or the most
recent  post-effective   amendment  thereof)  which,   individually  or  in  the
aggregate,  represent a fundamental  change in the information set forth in this
Registration  Statement  and (iii) to  include  any  material  information  with
respect  to  the  plan  of  distribution   not  previously   disclosed  in  this
Registration  Statement  or any  material  change  to such  information  in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
not  apply  if the  information  required  to be  included  in a  post-effective
amendment by those  paragraphs  is contained  in periodic  reports  filed by the
Registrant  pursuant  to Section  13 or  Section  15(d) of the 1934 Act that are
incorporated  by reference into this  Registration  Statement;  (2) that for the
purpose of determining any liability under the 1933 Act each such post-effective
amendment  shall be deemed to be a new  registration  statement  relating to the
securities  offered  therein and the  offering of such  securities  at that time
shall be deemed to be the initial bona fide offering thereof;  and (3) to remove
from  registration by means of a post-effective  amendment any of the securities
being registered which remain unsold at the termination of the Registrant's 1995
Stock  Option  Plan,  1995  Non-Employee  Directors  Stock  Option  Plan and the
Employee Stock Purchase Plan.

         B. The undersigned  Registrant  hereby undertakes that, for purposes of
determining  any liability  under the 1933 Act, each filing of the  Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference into this Registration Statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         C. Insofar as  indemnification  for liabilities  arising under the 1933
Act may be permitted  to  directors,  officers,  or  controlling  persons of the
Registrant pursuant to the indemnification  provisions  summarized in Item 6, or
otherwise, the Registrant has been advised that, in the opinion of the SEC, such
indemnification  is against  public policy as expressed in the 1933 Act, and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the Registrant of expenses incurred
or paid by a director,  officer,  or controlling person of the Registrant in the
successful  defense of any  action,  suit,  or  proceeding)  is asserted by such
director, officer, or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy  as  expressed  in the  1933  Act  and  will  be  governed  by the  final
adjudication of such issue.

                               SANDISK CORPORATION
                             1995 STOCK OPTION PLAN
                  AMENDED AND RESTATED AS OF FEBRUARY 10, 1997

                                   ARTICLE ONE

                               GENERAL PROVISIONS

       I.         PURPOSE OF THE PLAN

                  This  1995  Stock  Option  Plan is  intended  to  promote  the
interests of SanDisk Corporation, a Delaware corporation,  by providing eligible
persons with the  opportunity  to acquire a proprietary  interest,  or otherwise
increase their proprietary interest, in the Corporation as an incentive for them
to remain in the service of the Corporation.

                  Capitalized  terms  shall have the  meanings  assigned to such
terms in the attached Appendix.

      II.         ADMINISTRATION OF THE PLAN

                  A. The Committee  shall have sole and  exclusive  authority to
administer the Plan with respect to Section 16 Insiders.  Administration  of the
Plan with  respect to all other  persons  eligible  to  participate  may, at the
Board's  discretion,  be vested in the  Committee,  or the Board may  retain the
power to administer the Plan with respect to all such persons.

                  B.  Members of the  Committee  shall  serve for such period of
time as the Board may  determine and shall be subject to removal by the Board at
any time.

                  C. The  Plan  Administrator  shall,  within  the  scope of its
administrative  functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem  appropriate  for  proper  administration  of the  Plan  and to  make  such
determinations  under, and issue such interpretations of, the provisions of such
program and any  outstanding  options  thereunder  as it may deem  necessary  or
advisable.  Decisions  of  the  Plan  Administrator  within  the  scope  of  its
administrative  functions  under  the Plan  shall be final  and  binding  on all
parties who have an interest in the Plan or any option thereunder.

                  D.  Service on the  Committee  shall  constitute  service as a
Board member, and members of the Committee shall accordingly be entitled to full
indemnification  and reimbursement as Board members for their service. No member
of the Committee shall be liable for any act or omission made in good faith with
respect to the Plan or any option grants made under the Plan.


<PAGE>

     III.         ELIGIBILITY

                  A. The  persons  eligible  to  participate  in the Plan are as
follows:

                     (i) Employees,

                     (ii) Non-employee Board members, and

                     (iii)  consultants  and  other  independent   advisors  who
                     provide  services  to the  Corporation  (or any  Parent  or
                     Subsidiary).

                  B. The  Plan  Administrator  shall,  within  the  scope of its
administrative  jurisdiction  under the Plan,  have full  authority to determine
which eligible persons are to receive option grants, the time or times when such
option  grants  are to be made,  the number of shares to be covered by each such
grant,  the  status of the  granted  option as either an  Incentive  Option or a
Non-Statutory  Option,  the  time or times at which  each  option  is to  become
exercisable  and the vesting  schedule (if any)  applicable to the option shares
and the maximum term for which the option is to remain outstanding.

      IV.         STOCK SUBJECT TO THE PLAN

                  A. The  stock  issuable  under  the Plan  shall be  shares  of
authorized but unissued or reacquired Common Stock, including shares repurchased
by the  Corporation  on the open market.  The maximum number of shares of Common
Stock which may be issued  over the term of the Plan shall not exceed  5,998,711
shares.  Such share reserve includes (i) the initial reserve of 3,498,711 shares
which  reflects the 2:3 stock split  adopted by the Board on July 25, 1995,  and
(ii) the  additional  increase of 2,500,000  shares  authorized  by the Board on
February 10, 1997,  subject to stockholder  approval at the 1997 Annual Meeting.
The initial authorized share reserve was comprised of the number of shares which
remained available for issuance, as of the Effective Date, under the Predecessor
Plan as last  approved  by the  Corporation's  stockholders  prior to such date,
including the shares subject to the outstanding  options  incorporated  into the
Plan and any other  shares  which would have been  available  for future  option
grants under the Predecessor Plan.

                  B. No one person participating in the Plan may receive options
and separately  exercisable  stock  appreciation  rights for more than 1,000,000
shares of Common Stock in the aggregate over the term of the Plan.

                  C. Shares of Common Stock subject to outstanding options shall
be  available  for  subsequent  issuance  under the Plan to the  extent  (i) the
options (including any options incorporated from the Predecessor Plan) expire or
terminate  for any reason  prior to  exercise  in full or (ii) the  options  are
cancelled in accordance with the cancellation-regrant provisions of Article Two.
In addition,  unvested shares issued under the Plan and subsequently repurchased
by the Corporation,  at the original exercise price paid per share,

                                       2
<PAGE>

pursuant to the  Corporation's  repurchase  rights under the Plan shall be added
back to the number of shares of Common Stock  reserved  for  issuance  under the
Plan and shall  accordingly  be  available  for  reissuance  through one or more
subsequent option grants under the Plan.  However,  should the exercise price of
an option under the Plan (including any option incorporated from the Predecessor
Plan) be paid  with  shares of Common  Stock or  should  shares of Common  Stock
otherwise issuable under the Plan be withheld by the Corporation in satisfaction
of the  withholding  taxes incurred in connection with the exercise of an option
under the Plan, then the number of shares of Common Stock available for issuance
under the Plan  shall be  reduced  by the gross  number of shares  for which the
option is exercised,  and not by the net number of shares of Common Stock issued
to the holder of such option.

                  D. Should any change be made to the Common  Stock by reason of
any stock  split,  stock  dividend,  recapitalization,  combination  of  shares,
exchange of shares or other change  affecting the outstanding  Common Stock as a
class  without  the   Corporation's   receipt  of   consideration,   appropriate
adjustments  shall be made to (i) the maximum  number and/or class of securities
issuable  under the Plan,  (ii) the number and/or class of securities  for which
any  one  person  may  be  granted  options  and  separately  exercisable  stock
appreciation  rights over the term of the Plan and (iii) the number and/or class
of securities and the exercise price per share in effect under each  outstanding
option (including any option incorporated from the Predecessor Plan) in order to
prevent the dilution or  enlargement  of benefits  thereunder.  The  adjustments
determined by the Plan Administrator shall be final, binding and conclusive.

                                   ARTICLE TWO

                              OPTION GRANT PROGRAM

       I.         OPTION TERMS

                  Each option shall be evidenced by one or more documents in the
form  approved  by the Plan  Administrator;  provided,  however,  that each such
document shall comply with the terms specified below.  Each document  evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

                  A.       Exercise Price.

                           1. The exercise price per share shall be fixed by the
Plan  Administrator but shall not be less than eighty-five  percent (85%) of the
Fair Market Value per share of Common Stock on the option grant date.

                           2. The exercise  price shall become  immediately  due
upon exercise of the option and shall, subject to the provisions of Section I of
Article Three and the documents evidencing the option, be payable in one or more
of the forms specified below:

                              (i) cash or check made payable to the Corporation,

                              (ii) shares of Common Stock held for the requisite
         period  necessary to avoid a charge to the  Corporation's  earnings for
         financial  reporting  purposes  and valued at Fair Market  Value on the
         Exercise Date, or

                              (iii) to the extent the  option is  exercised  for
         vested shares, through a special sale and remittance procedure pursuant
         to which the Optionee shall concurrently  provide  irrevocable  written
         instructions to (a) a  Corporation-designated  brokerage firm to effect
         the  immediate   sale  of  the  purchased   shares  and  remit  to  the
         Corporation, out of the sale proceeds available on the settlement date,
         sufficient funds to cover the aggregate  exercise price payable for the
         purchased  shares plus all applicable  Federal,  state and local income
         and  employment  taxes  required to be withheld by the  Corporation  by
         reason  of such  exercise  and  (b)  the  Corporation  to  deliver  the
         certificates  for the purchased  shares directly to such brokerage firm
         in order to complete the sale.

                  Except to the extent  such sale and  remittance  procedure  is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

                                       4
<PAGE>

                  B.  Exercise  and  Term  of  Options.  Each  option  shall  be
exercisable  at such time or times,  during  such  period and for such number of
shares as shall be  determined  by the Plan  Administrator  and set forth in the
documents evidencing the option.  However, no option shall have a term in excess
of ten (10) years measured from the option grant date.

                  C.       Effect of Termination of Service.

                           1. The following provisions shall govern the exercise
of any  options  held by the  Optionee  at the time of  cessation  of Service or
death:

                              (i)  Any  option  outstanding  at the  time of the
         Optionee's cessation of Service for any reason shall remain exercisable
         for such period of time  thereafter  as shall be determined by the Plan
         Administrator and set forth in the documents evidencing the option, but
         no such option shall be exercisable  after the expiration of the option
         term.

                              (ii) Any option exercisable in whole or in part by
         the Optionee at the time of death may be subsequently  exercised by the
         personal  representative  of the Optionee's  estate or by the person or
         persons to whom the option is  transferred  pursuant to the  Optionee's
         will or in accordance with the laws of descent and distribution.

                              (iii) During the applicable  post-Service exercise
         period,  the option may not be exercised in the aggregate for more than
         the number of vested shares for which the option is  exercisable on the
         date of the Optionee's cessation of Service. Upon the expiration of the
         applicable  exercise  period or (if earlier) upon the expiration of the
         option term, the option shall terminate and cease to be outstanding for
         any vested shares for which the option has not been exercised. However,
         the option shall, immediately upon the Optionee's cessation of Service,
         terminate  and  cease  to be  outstanding  to  the  extent  it  is  not
         exercisable for vested shares on the date of such cessation of Service.

                              (iv) Should the  Optionee's  Service be terminated
         for Misconduct, then all outstanding options held by the Optionee shall
         terminate immediately and cease to be outstanding.

                              (v) In the event of a Corporate  Transaction,  the
         provisions  of Section III of this  Article Two shall govern the period
         for which the outstanding  options are to remain exercisable  following
         the Optionee's  cessation of Service and shall supersede any provisions
         to the contrary in this section.

                                       5
<PAGE>

                           2. The Plan Administrator  shall have the discretion,
exercisable  either at the time an option is  granted  or at any time  while the
option remains outstanding, to:

                              (i) extend the period of time for which the option
         is to remain exercisable  following the Optionee's cessation of Service
         from the period  otherwise  in effect for that  option to such  greater
         period of time as the Plan Administrator shall deem appropriate, but in
         no event beyond the expiration of the option term, and/or

                              (ii) permit the option to be exercised, during the
         applicable  post-Service  exercise period, not only with respect to the
         number of  vested  shares of  Common  Stock  for which  such  option is
         exercisable at the time of the Optionee's cessation of Service but also
         with  respect  to one or more  additional  installments  in  which  the
         Optionee would have vested under the option had the Optionee  continued
         in Service.

                  D. Stockholder  Rights.  The holder of an option shall have no
stockholder  rights with respect to the shares  subject to the option until such
person shall have  exercised  the option,  paid the exercise  price and become a
holder of record of the purchased shares.

                  E. Repurchase Rights.  The Plan  Administrator  shall have the
discretion to grant options which are  exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation  shall have the right to repurchase,  at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable  (including the period and procedure for exercise and
the appropriate  vesting schedule for the purchased shares) shall be established
by the  Plan  Administrator  and  set  forth  in the  document  evidencing  such
repurchase right.

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

                                       6
<PAGE>

      II.         INCENTIVE OPTIONS

                  The terms specified below shall be applicable to all Incentive
Options.  Except as  modified  by the  provisions  of this  Section  II, all the
provisions of the Plan shall be applicable to Incentive  Options.  Options which
are specifically  designated as Non-Statutory Options when issued under the Plan
shall not be subject to the terms of this Section II.

                  A.  Eligibility.  Incentive  Options  may only be  granted  to
Employees.

                  B. Exercise  Price.  The exercise price per share shall not be
less  than one  hundred  percent  (100%) of the Fair  Market  Value per share of
Common Stock on the option grant date.

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

                  D.  10%  Stockholder.  If any  Employee  to whom an  Incentive
Option is granted is a 10% Stockholder,  then the exercise price per share shall
not be less than one  hundred ten  percent  (110%) of the Fair Market  Value per
share of Common  Stock on the option  grant date,  and the option term shall not
exceed five (5) years measured from the option grant date.

     III.         CORPORATE TRANSACTION/CHANGE IN CONTROL

                  A. In the event of any Corporate Transaction, each outstanding
option  shall   automatically   accelerate  so  that  each  such  option  shall,
immediately  prior to the effective  date of the Corporate  Transaction,  become
fully  exercisable  for all of the shares of Common Stock at the time subject to
such option and may be exercised for any or all of those shares as  fully-vested
shares of Common Stock.  However,  an outstanding option shall not so accelerate
if and to the  extent:  (i) such  option is, in  connection  with the  Corporate
Transaction,  either to be  assumed  by the  successor  corporation  (or  parent
thereof) or to be replaced  with a comparable  option to purchase  shares of the
capital stock of the successor corporation (or parent thereof), (ii) such option
is to be replaced with a cash  incentive  program of the  successor  corporation
which preserves the spread existing on the unvested option shares at the time of
the Corporate  Transaction and provides for subsequent payout

                                       7
<PAGE>


in accordance with the same vesting schedule  applicable to such option or (iii)
the acceleration of such option is subject to other  limitations  imposed by the
Plan  Administrator at the time of the option grant. The determination of option
comparability  under  clause (i) above shall be made by the Plan  Administrator,
and its determination shall be final, binding and conclusive.

                  B. All  outstanding  repurchase  rights  shall also  terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall  immediately  vest in full,  in the  event of any  Corporate  Transaction,
except to the  extent:  (i) those  repurchase  rights are to be  assigned to the
successor  corporation  (or parent  thereof) in connection  with such  Corporate
Transaction or (ii) such accelerated  vesting is precluded by other  limitations
imposed by the Plan Administrator at the time the repurchase right is issued.

                  C.  The  Plan   Administrator   shall  have  the   discretion,
exercisable  either at the time the  option is  granted or at any time while the
option remains outstanding,  to provide for the automatic acceleration of one or
more  outstanding  options  (and  the  automatic  termination  of  one  or  more
outstanding repurchase rights with the immediate vesting of the shares of Common
Stock subject to those rights) upon the  occurrence of a Corporate  Transaction,
whether or not those options are to be assumed or replaced (or those  repurchase
rights are to be assigned) in the Corporate Transaction.

                  D.  Immediately  following the  consummation  of the Corporate
Transaction,   all   outstanding   options  shall  terminate  and  cease  to  be
outstanding,  except to the extent  assumed  by the  successor  corporation  (or
parent thereof).

                  E. Each option which is assumed in connection with a Corporate
Transaction  shall be appropriately  adjusted,  immediately after such Corporate
Transaction,  to apply to the number and class of  securities  which  would have
been issuable to the Optionee in consummation of such Corporate  Transaction had
the option  been  exercised  immediately  prior to such  Corporate  Transaction.
Appropriate  adjustments  shall  also be made to (i) the  number  and  class  of
securities  available  for issuance  under the Plan on both an aggregate and per
Optionee basis following the consummation of such Corporate Transaction and (ii)
the exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same.

                  F. Any options  which are assumed or replaced in the Corporate
Transaction and do not otherwise  accelerate at that time,  shall  automatically
accelerate (and any of the Corporation's  outstanding repurchase rights which do
not  otherwise  terminate  at  the  time  of  the  Corporate  Transaction  shall
automatically  terminate  and the  shares  of  Common  Stock  subject  to  those
terminated  rights shall  immediately  vest in full) in the event the Optionee's
Service should  subsequently  terminate by reason of an Involuntary

                                       8
<PAGE>

Termination  within  twelve (12) months  following  the  effective  date of such
Corporate  Transaction.  Any options so accelerated shall remain exercisable for
fully-vested  shares until the earlier of (i) the  expiration of the option term
or (ii) the  expiration of the one (1)-year  period  measured from the effective
date of the Involuntary Termination.

                  G.  The  Plan   Administrator   shall  have  the   discretion,
exercisable  either at the time the  option is  granted or at any time while the
option remains outstanding, to (i) provide for the automatic acceleration of one
or more  outstanding  options  (and  the  automatic  termination  of one or more
outstanding repurchase rights with the immediate vesting of the shares of Common
Stock  subject to those  rights) upon the  occurrence  of a Change in Control or
(ii)  condition  any  such  option  acceleration  (and  the  termination  of any
outstanding  repurchase rights) upon the subsequent  Involuntary  Termination of
the Optionee's Service within a specified period following the effective date of
such Change in Control.  Any options  accelerated in connection with a Change in
Control  shall  remain  fully   exercisable   until  the  expiration  or  sooner
termination of the option term.

                  H.  The  portion  of  any  Incentive  Option   accelerated  in
connection  with a  Corporate  Transaction  or Change in  Control  shall  remain
exercisable as an Incentive Option only to the extent the applicable One Hundred
Thousand Dollar limitation is not exceeded. To the extent such dollar limitation
is exceeded,  the  accelerated  portion of such option shall be exercisable as a
Non-Statutory Option under the Federal tax laws.

                  I. The grant of options  under the Option Grant  Program shall
in no way affect the right of the Corporation to adjust, reclassify,  reorganize
or otherwise change its capital or business structure or to merge,  consolidate,
dissolve,  liquidate  or sell or  transfer  all or any part of its  business  or
assets.

      IV.         CANCELLATION AND REGRANT OF OPTIONS

                  The Plan Administrator  shall have the authority to effect, at
any time and from time to time, with the consent of the affected option holders,
the  cancellation  of any or all  outstanding  options  under the  Option  Grant
Program (including  outstanding options  incorporated from the Predecessor Plan)
and to grant in substitution  new options  covering the same or different number
of shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

       V.         STOCK APPRECIATION RIGHTS

                  A. The Plan Administrator  shall have full power and authority
to grant to selected Optionees tandem stock  appreciation  rights and/or limited
stock appreciation rights.

                                       9
<PAGE>


                  B. The following  terms shall govern the grant and exercise of
tandem stock appreciation rights:

                              (i)  One or  more  Optionees  may be  granted  the
         right,  exercisable  upon  such  terms  as the Plan  Administrator  may
         establish,  to elect between the exercise of the underlying  option for
         shares of Common Stock and the surrender of that option in exchange for
         a distribution from the Corporation in an amount equal to the excess of
         (A) the Fair Market Value (on the option  surrender date) of the number
         of  shares  in which  the  Optionee  is at the time  vested  under  the
         surrendered  option  (or  surrendered  portion  thereof)  over  (B) the
         aggregate exercise price payable for such shares.

                              (ii) No such option  surrender  shall be effective
         unless it is approved by the Plan Administrator. If the surrender is so
         approved, then the distribution to which the Optionee shall be entitled
         may be made in shares of Common  Stock  valued at Fair Market  Value on
         the option  surrender  date, in cash, or partly in shares and partly in
         cash,  as the Plan  Administrator  shall in its  sole  discretion  deem
         appropriate.

                              (iii) If the surrender of an option is rejected by
         the Plan Administrator,  then the Optionee shall retain whatever rights
         the Optionee had under the surrendered  option (or surrendered  portion
         thereof) on the option  surrender  date and may exercise such rights at
         any time  prior to the later of (A) five (5)  business  days  after the
         receipt of the rejection notice or (B) the last day on which the option
         is otherwise  exercisable in accordance with the terms of the documents
         evidencing  such  option,  but in no event may such rights be exercised
         more than ten (10) years after the option grant date.

                  C. The following  terms shall govern the grant and exercise of
limited stock appreciation rights:

                              (i) One or more Section 16 Insiders may be granted
         limited  stock  appreciation  rights with respect to their  outstanding
         options.

                              (ii) Upon the  occurrence of a Hostile  Take-Over,
         each such  individual  holding one or more  options with such a limited
         stock   appreciation   right   shall  have  the   unconditional   right
         (exercisable  for a  thirty  (30)-day  period  following  such  Hostile
         Take-Over)  to surrender  each such option to the  Corporation,  to the
         extent  the  option is at the time  exercisable  for  vested  shares of
         Common Stock. In return for the surrendered  option, the Optionee shall
         receive a cash  distribution from the Corporation in an amount equal to
         the excess of (A) the  Take-Over  Price of the  shares of Common  Stock
         which  are at  the  time  vested  under  each  surrendered  option  (or

                                       10
<PAGE>


         surrendered  portion  thereof)  over (B) the aggregate  exercise  price
         payable for such shares.  Such cash  distribution  shall be paid within
         five (5) days following the option surrender date.

                              (iii) The Plan Administrator shall pre-approve, at
         the time the limited right is granted,  the subsequent exercise of that
         right in accordance  with the terms of the grant and the  provisions of
         this Section V. No additional approval of the Plan Administrator or the
         Board shall be required at the time of the actual option  surrender and
         cash distribution.

                              (iv) The  balance  of the  option  (if any)  shall
         continue  in full force and  effect in  accordance  with the  documents
         evidencing such option.

                                  MISCELLANEOUS


       I.         FINANCING

                  A. The Plan  Administrator  may permit any Optionee to pay the
option  exercise  price by  delivering a promissory  note payable in one or more
installments. The terms of any such promissory note (including the interest rate
and the terms of repayment)  shall be established by the Plan  Administrator  in
its sole discretion. Promissory notes may be authorized with or without security
or collateral.  In all events,  the maximum credit available to the Optionee may
not exceed the sum of (i) the aggregate  option  exercise  price payable for the
purchased  shares plus (ii) any Federal,  state and local income and  employment
tax liability incurred by the Optionee in connection with the option exercise.

                  B. The Plan  Administrator  may, in its discretion,  determine
that one or more such  promissory  notes shall be subject to  forgiveness by the
Corporation  in whole or in part upon such terms as the Plan  Administrator  may
deem appropriate.

      II.         TAX WITHHOLDING

                  A. The  Corporation's  obligation to deliver  shares of Common
Stock upon the exercise of options or stock  appreciation  rights under the Plan
shall be subject to the satisfaction of all applicable Federal,  state and local
income and employment tax withholding requirements.

                  B. The Plan Administrator may, in its discretion,  provide any
or all holders of  Non-Statutory  Options with the right to use shares of Common
Stock in  satisfaction  of all or part of the Taxes  incurred by such holders in
connection with the exercise of their options. Such right may be provided to any
such holder in either or both of the following formats:

                              (i) Stock  Withholding:  The  election to have the
         Corporation  withhold,  from  the  shares  of  Common  Stock  otherwise
         issuable upon the exercise of such  Non-Statutory  Option, a portion of
         those  shares  with  an  aggregate  Fair  Market  Value  equal  to  the
         percentage  of the Taxes (not to exceed  one  hundred  percent  (100%))
         designated by the holder.

                                       12
<PAGE>


                              (ii) Stock  Delivery:  The  election to deliver to
         the Corporation, at the time the Non-Statutory Option is exercised, one
         or more  shares of Common  Stock  previously  acquired  by such  holder
         (other  than in  connection  with the option  exercise  triggering  the
         Taxes) with an aggregate  Fair Market Value equal to the  percentage of
         the Taxes (not to exceed one hundred percent (100%))  designated by the
         holder.

     III.         EFFECTIVE DATE AND TERM OF THE PLAN

                  A. The Plan became effective on the November 7, 1995 Effective
Date  after  adoption  by the  Board  on July  25,  1995,  and  approval  by the
Corporation's stockholders in August 1995.

                  B. The Plan was  amended on February  10, 1997 (the  "February
1997  Amendment")  to effect the following  changes:  (i) increase the number of
shares of Common Stock  authorized  for issuance over the term of the Plan by an
additional 2,500,000 shares, (ii) render the non-employee Board members eligible
to receive  option  grants under the Plan,  (iii) allow  unvested  shares issued
under the Plan and  subsequently  repurchased  by the  Corporation at the option
exercise  price paid per share to be  reissued  under the Plan and (iv) effect a
series  of  technical  changes  to the  provisions  of the Plan  (including  the
stockholder  approval  requirements)  in order to take  advantage  of the recent
amendments  to Rule 16b-3 of the  Securities  Exchange Act of 1934 which exempts
certain  officer and director  transactions  under the Plan from the short-swing
liability provisions of the Federal securities laws. The February 1997 Amendment
is subject to  stockholder  approval at the 1997 Annual  Meeting,  and no option
grants  made on the basis of the  February  1997  share  increase  shall  become
exercisable  in whole or in part unless and until the February 1997 Amendment is
approved by the stockholders.  Should such stockholder  approval not be obtained
at the 1997 Annual Meeting, then each option grant made pursuant to the February
1997 share  increase  shall  terminate and cease to remain  outstanding,  and no
further  option  grants  shall  be made on the  basis  of that  share  increase.
However,  the  provisions  of the  Plan as in  effect  immediately  prior to the
February 1997 Amendment shall automatically be reinstated, and option grants may
thereafter  continue to be made  pursuant to the  reinstated  provisions  of the
Plan. All option grants made prior to the February 1997  Amendment  shall remain
outstanding  in  accordance  with the terms  and  conditions  of the  respective
instruments  evidencing those options or issuances,  and nothing in the February
1997 Amendment shall be deemed to modify or in any way affect those  outstanding
options  or  issuances.   Subject  to  the  foregoing   limitations,   the  Plan
Administrator  may make option grants under the Plan at any time before the date
fixed herein for the termination of the Plan.

                  C. The Plan shall serve as the  successor  to the  Predecessor
Plan,  and no further  option  grants shall be made under the  Predecessor  Plan
after the Effective Date. All options  outstanding under the Predecessor Plan as
of such date shall,  immediately upon approval of the Plan by the Corporations's
stockholders,  be incorporated into the Plan and

                                       13
<PAGE>


treated as outstanding options under the Plan. However,  each outstanding option
so  incorporated  shall  continue  to be  governed  solely  by the  terms of the
documents  evidencing such option,  and no provision of the Plan shall be deemed
to affect or otherwise  modify the rights or  obligations of the holders of such
incorporated  options  with  respect  to their  acquisition  of shares of Common
Stock.

                  D. The provisions of the Plan (including,  without limitation,
the option/vesting  acceleration provisions of Article Two relating to Corporate
Transactions   and  Changes  in  Control)  may,  in  the  Plan   Administrator's
discretion, be extended to one or more options incorporated from the Predecessor
Plan which do not otherwise provide for such acceleration.

                  E. The Plan shall  terminate upon the earliest of (i) July 24,
2005,  (ii) the date on which all shares  available for issuance  under the Plan
have been issued pursuant to the exercise of the options under the Plan or (iii)
the  termination  of all  outstanding  options in  connection  with a  Corporate
Transaction.  Upon such Plan termination,  all options  outstanding on such date
shall  thereafter  continue  to have  force and  effect in  accordance  with the
provisions of the documents evidencing such options.

      IV.         AMENDMENT OF THE PLAN

                  A. The Board  shall  have  complete  and  exclusive  power and
authority to amend or modify the Plan in any or all respects.  However,  no such
amendment or modification shall adversely affect the rights and obligations with
respect to options or stock  appreciation  rights at the time outstanding  under
the Plan unless the  Optionee  consents to such  amendment or  modification.  In
addition, certain amendments may require stockholder approval in accordance with
applicable laws and regulations.

                  B.  Options to purchase  shares of Common Stock may be granted
that are in excess of the number of shares then available for issuance under the
Plan,  provided  any excess  shares  actually  issued  are held in escrow  until
stockholder  approval  of an  amendment  sufficiently  increasing  the number of
shares of Common Stock  available  for issuance  under the Plan is obtained.  If
such  stockholder  approval is not obtained  within twelve (12) months after the
date the first such excess issuances are made, then (i) any unexercised  options
granted  on the basis of such  excess  shares  shall  terminate  and cease to be
outstanding and (ii) the Corporation  shall promptly refund to the Optionees the
exercise  price paid for any  excess  shares  issued  under the Plan and held in
escrow,  together with interest (at the applicable  Short Term Federal Rate) for
the period the shares were held in escrow,  and such shares  shall  thereupon be
automatically cancelled and cease to be outstanding.

       V.         USE OF PROCEEDS

                  Any cash proceeds received by the Corporation from the sale of
shares  of  Common  Stock  under the Plan  shall be used for  general  corporate
purposes.

                                       14

      VI.         REGULATORY APPROVALS

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

                  B. No shares of Common  Stock or other  assets shall be issued
or  delivered  under the Plan unless and until there shall have been  compliance
with all applicable requirements of Federal and state securities laws, including
the filing and  effectiveness  of the Form S-8  registration  statement  for the
shares of Common  Stock  issuable  under the Plan,  and all  applicable  listing
requirements  of  any  stock  exchange  (or  the  Nasdaq  National  Market,   if
applicable) on which Common Stock is then listed for trading.

     VII.         NO EMPLOYMENT/SERVICE RIGHTS

                  Nothing in the Plan shall  confer upon the  Optionee any right
to continue in Service for any period of specific  duration or interfere with or
otherwise  restrict in any way the rights of the  Corporation  (or any Parent or
Subsidiary employing or retaining such person) or of the Optionee,  which rights
are hereby expressly reserved by each, to terminate such person's Service at any
time for any reason, with or without cause.

               (i) If the  Common  Stock is at the  time  traded  on the  Nasdaq
         National  Market,  then  the Fair  Market  Value  shall be the  closing

         such  price is  reported  by the  National  Association  of  Securities
         Dealers on the Nasdaq National Market or any successor system. If there
         is no  closing  selling  price  for the  Common  Stock  on the  date in

                  1995 NON-EMPLOYEE DIRECTORS STOCK OPTION PLAN

                  AMENDED AND RESTATED AS OF FEBRUARY 10, 1997

                                   ARTICLE ONE

                               GENERAL PROVISIONS


       I.         PURPOSE OF THE PLAN

                  This 1995 Non-Employee Directors Stock Option Plan is intended
to promote the  interests of SanDisk  Corporation,  a Delaware  corporation,  by
providing the non-employee  members of the Board with the opportunity to acquire
a proprietary interest, or otherwise increase their proprietary interest, in the
Corporation  as  an  incentive  for  them  to  remain  in  the  service  of  the
Corporation.

                  Capitalized  terms  shall have the  meanings  assigned to such
terms in the attached Appendix.

      II.         ADMINISTRATION OF THE PLAN

                  The terms of each  option  grant  (including  the  timing  and
pricing of the option  grant) shall be  determined  by the express  terms of the
Plan,  and neither the Board nor any  committee of the Board shall  exercise any
discretionary functions with respect to option grants made pursuant to the Plan.

     III.         ELIGIBILITY

                  The  individuals  eligible to receive  option grants under the
Plan  shall be (i) those  individuals  who are  serving  as  non-employee  Board
members  on the  Effective  Date  or who  are  first  elected  or  appointed  as
non-employee Board members on or after such date, whether through appointment by
the  Board  or  election  by the  Corporation's  stockholders,  and  (ii)  those
individuals  who continue to serve as  non-employee  Board  members after one or
more Annual  Stockholders  Meetings  beginning with the 1996 Annual  Meeting.  A
non-employee  Board  member  who  has  previously  been  in  the  employ  of the
Corporation  (or any Parent or  Subsidiary)  shall not be eligible to receive an
option grant under the Plan on the Effective Date or at the time he or she first
becomes a non-employee  Board member,  but shall be eligible to receive periodic
option grants under the Plan upon his or her continued service as a non-employee
Board member following one or more Annual Stockholders Meetings.


<PAGE>


      IV.         STOCK SUBJECT TO THE PLAN

                  A. The  stock  issuable  under  the Plan  shall be  shares  of
authorized but unissued or reacquired Common Stock, including shares repurchased
by the  Corporation  on the open market.  The maximum number of shares of Common
Stock  which may be issued  over the term of the Plan shall not  exceed  200,000
shares.1  Such share  reserve  includes (i) the initial share reserve of 150,000
shares  approved by the  stockholders  in August  1995,  and (ii) an  additional
50,000 share increase  authorized by the Board on February 10, 1997,  subject to
stockholder  approval  at the 1997  Annual  Stockholders  Meeting.  No shares of
Common Stock shall be issued  under the Plan on the basis of the  February  1997
share increase unless that increase is approved by the  stockholders at the 1997
Annual Meeting.

                  B. Shares of Common Stock subject to outstanding options shall
be available for  subsequent  issuance  under the Plan to the extent the options
expire or  terminate  for any reason  prior to  exercise in full.  In  addition,
unvested  shares  issued  under  the Plan and  subsequently  repurchased  by the
Corporation,  at the  original  exercise  price paid per share,  pursuant to the
Corporation's repurchase rights under the Plan shall be added back to the number
of  shares  of  Common  Stock  reserved  for  issuance  under the Plan and shall
accordingly be available for reissuance  through one or more  subsequent  option
grants under the Plan. However,  shares subject to any option or portion thereof
surrendered  in  accordance  with Article Two shall reduce on a  share-for-share
basis the number of shares of Common Stock  available  for  subsequent  issuance
under the Plan.  Should the  exercise  price of an option under the Plan be paid
with shares of Common Stock, then the number of shares of Common Stock available
for  issuance  under the Plan shall be reduced by the gross number of shares for
which the  option is  exercised,  and not by the net  number of shares of Common
Stock issued to the holder of such option.

                  C. Should any change be made to the Common  Stock by reason of
any stock  split,  stock  dividend,  recapitalization,  combination  of  shares,
exchange of shares or other change  affecting the outstanding  Common Stock as a
class  without  the   Corporation's   receipt  of   consideration,   appropriate
adjustments  shall be made to (i) the maximum  number and/or class of securities
issuable  under the Plan,  (ii) the number and/or class of securities  for which
option grants are to be  subsequently  made per Eligible  Director and (iii) the
number  and/or class of  securities  and the exercise  price per share in effect
under each outstanding option in order to prevent the dilution or enlargement of
benefits thereunder. The adjustments to the outstanding options shall be made by
the Board and shall be final, binding and conclusive.

1995.

                              OPTION GRANT PROGRAM

       I.         OPTION TERMS

                  A.  Grant  Dates.  Option  grants  shall be made on the  dates
specified below:

                     1.  Each  Eligible  Director  who is a  non-employee  Board
member on the Effective Date and who has not previously received an option grant
from the Corporation  shall  automatically be granted,  on the Effective Date, a
Non-Statutory Option to purchase 16,000 shares of Common Stock.

                     2. Each Eligible Director who is first elected or appointed
as  a   non-employee   Board  member  on  or  after  the  Effective  Date  shall
automatically  be granted,  on the date of such initial  election or appointment
(as the case may be), a Non-Statutory Option to purchase 16,000 shares of Common
Stock.

                     3.  On  the  date  of  each  Annual  Stockholders  Meeting,
beginning with the 1996 Annual  Meeting,  each  individual who is to continue to
serve as an  Eligible  Director  after  such  meeting,  shall  automatically  be
granted,  whether or not such  individual is standing for re-election as a Board
member at that Annual Meeting, a Non-Statutory  Option to purchase an additional
4,000  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 of such
Annual Meeting. There shall be no limit on the number of such 4,000-share option
grants any one  Eligible  Director  may receive  over his or her period of Board
service.

                  B. Exercise Price.

                     1.  The  exercise  price  per  share  shall be equal to one
hundred percent (100%) of the Fair Market Value per share of Common Stock on the
option grant date.

                     2. The  exercise  price shall become  immediately  due upon
exercise  of the  option  and  shall  be  payable  in one or more  of the  forms
specified below:

                           (i) cash or check made payable to the Corporation,

                           (ii)  shares of Common  Stock held for the  requisite
         period  necessary to avoid a charge to the  Corporation's  earnings for
         financial  reporting  purposes  and valued at Fair Market  Value on the
         Exercise Date, or

                                       3
<PAGE>


                           (iii) to the  extent  the  option  is  exercised  for
         vested shares, through a special sale and remittance procedure pursuant
         to which the Optionee shall concurrently  provide  irrevocable  written
         instructions to (A) a  Corporation-designated  brokerage firm to effect
         the  immediate   sale  of  the  purchased   shares  and  remit  to  the
         Corporation, out of the sale proceeds available on the settlement date,
         sufficient funds to cover the aggregate  exercise price payable for the
         purchased  shares plus all applicable  Federal,  state and local income
         and  employment  taxes  required to be withheld by the  Corporation  by
         reason  of such  exercise  and  (B)  the  Corporation  to  deliver  the
         certificates  for the purchased  shares directly to such brokerage firm
         in order to complete the sale.

                  Except to the extent  such sale and  remittance  procedure  is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

                  C.  Option  Term.  Each  option  shall have a term of ten (10)
years measured from the option grant date.

                  D.  Exercise  and  Vesting of Options.  Each  option  shall be
immediately exercisable for any or all of the option shares. However, any shares
purchased under the option shall be subject to repurchase by the Corporation, at
the  exercise  price  paid per share,  upon the  Optionee's  cessation  of Board
service prior to vesting in those shares. Each initial grant shall vest, and the
Corporation's  repurchase  right shall lapse,  in a series of four (4) equal and
successive  annual  installments over the Optionee's period of continued service
as a Board member,  with the first such  installment to vest upon the Optionee's
completion of one (1) year of Board service measured from the option grant date.
Each annual  grant  shall vest,  and the  Corporation's  repurchase  right shall
lapse, upon the Optionee's  completion of one (1) year of Board service measured
from the option grant date.

                  E.  Effect of  Termination  of Board  Service.  The  following
provisions  shall govern the exercise of any options held by the Optionee at the
time the Optionee ceases to serve as a Board member:

                           (i) The  Optionee  (or,  in the  event of  Optionee's
         death,  the personal  representative  of the  Optionee's  estate or the
         person or  persons to whom the option is  transferred  pursuant  to the
         Optionee's  will  or  in  accordance  with  the  laws  of  descent  and
         distribution)  shall have a twelve (12)-month period following the date
         of such  cessation  of Board  service  in which to  exercise  each such
         option.

                           (ii) During the twelve  (12)-month  exercise  period,
         the  option may not be  exercised  in the  aggregate  for more than the
         number of vested shares for which the option is exercisable at the time
         of the Optionee's cessation of Board service.

                                       4
<PAGE>


                           (iii) Should the  Optionee  cease to serve as a Board
         member by reason of death or Permanent  Disability,  then all shares at
         the time  subject to the  option  shall  immediately  vest so that such
         option may, during the twelve (12)-month exercise period following such
         cessation of Board service, be exercised for all or any portion of such
         shares as fully-vested shares.

                           (iv) In no event shall the option remain  exercisable
         after the  expiration  of the option term.  Upon the  expiration of the
         twelve  (12)-month  exercise period or (if earlier) upon the expiration
         of the  option  term,  the  option  shall  terminate  and  cease  to be
         outstanding  for any  vested  shares  for which the option has not been
         exercised.  However, the option shall,  immediately upon the Optionee's
         cessation of Board  service,  terminate and cease to be  outstanding to
         the extent it is not  exercisable for vested shares on the date of such
         cessation of Board service.

                  F. Stockholder  Rights.  The holder of an option shall have no
stockholder  rights with respect to the shares  subject to the option until such
person shall have  exercised  the option,  paid the exercise  price and become a
holder of record of the purchased shares.

                  G. Limited  Transferability  of Options.  An automatic  option
granted under the Plan may, in connection  with the  Optionee's  estate plan, be
assigned  in whole or in part  during  the  Optionee's  lifetime  to one or more
members of the Optionee's immediate family or to a trust established exclusively
for one or more such family members.  The assigned portion may only be exercised
by the  person or  persons  who  acquire a  proprietary  interest  in the option
pursuant to the assignment.  The terms  applicable to the assigned portion shall
be the  same as  those  in  effect  for the  option  immediately  prior  to such
assignment  and shall be set forth in such  documents  issued to the assignee as
the Plan Administrator may deem appropriate.

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

                  A. In the event of any  Corporate  Transaction,  the shares of
Common Stock at the time subject to each  outstanding  option but not  otherwise
vested  shall  automatically  vest  in  full so that  each  such  option  shall,
immediately prior to the specified effective date of the Corporate  Transaction,
become  fully  exercisable  for all of the  shares of  Common  Stock at the time
subject  to such  option  and may be  exercised  for all or any  portion of such
shares as  fully-vested  shares  of  Common  Stock.  Immediately  following  the
consummation of the Corporate Transaction, each option grant shall terminate and
cease  to be  outstanding,  except  to  the  extent  assumed  by  the  successor
corporation (or parent thereof).

                                       5
<PAGE>


                  B. In  connection  with any Change in  Control,  the shares of
Common Stock at the time subject to each  outstanding  option but not  otherwise
vested  shall  automatically  vest  in  full so that  each  such  option  shall,
immediately  prior to the effective date of the Change in Control,  become fully
exercisable  for all of the shares of Common  Stock at the time  subject to such
option  and  may  be  exercised  for  all or  any  portion  of  such  shares  as
fully-vested  shares of Common Stock. Each such option shall remain  exercisable
for such  fully-vested  option shares until the expiration of the option term or
the surrender of the option in connection with a Hostile Take-Over.

                  C. Upon the  occurrence of a Hostile  Take-Over,  the Optionee
shall have a thirty  (30)-day  period in which to surrender  to the  Corporation
each option held by him or her.  The  Optionee  shall in return be entitled to a
cash  distribution  from the Corporation in an amount equal to the excess of (i)
the  Take-Over  Price of the shares of Common  Stock at the time  subject to the
surrendered  option (whether or not the Optionee is otherwise at the time vested
in those shares) over (ii) the aggregate exercise price payable for such shares.
Such  cash  distribution  shall  be paid  within  five (5)  days  following  the
surrender of the option to the Corporation. Stockholder approval of the February
10, 1997  restatement of the Plan shall  constitute  pre-approval of each option
surrender right subsequently  granted under the Plan and the subsequent exercise
of that right in accordance  with the terms and provisions of this Section II.C.
No  additional  approval  of the Board or any  committee  of the Board  shall be
required at the time of the actual option surrender and cash distribution.

                  D. The grant of options  under the Plan shall in no way affect
the right of the  Corporation  to adjust,  reclassify,  reorganize  or otherwise
change its capital or business  structure  or to merge,  consolidate,  dissolve,
liquidate or sell or transfer all or any part of its business or assets.

                                  MISCELLANEOUS


     III.         EFFECTIVE DATE AND TERM OF THE PLAN

                  A. The Plan became effective on the November 7, 1995 Effective
Date  after  adoption  by the  Board  on  July  25,  1995  and  approval  by the
Corporation's stockholders in August 1995.

                  B. The Plan was  amended on February  10, 1997 (the  "February
1997  Amendment")  to effect the following  changes:  (i) increase the number of
shares of Common Stock  authorized  for issuance over the term of the Plan by an
additional  50,000 shares,  (ii) allow unvested shares issued under the Plan and
subsequently  repurchased by the  Corporation at the option  exercise price paid
per share to be reissued  under the Plan and (iii)  effect a series of technical
changes  to  the  provisions  of  the  Plan  (including   stockholder   approval
requirements) in order to take advantage of the recent  amendments to Rule 16b-3
of the  Securities  Exchange  Act of 1934  which  exempts  certain  officer  and
director  transactions under the Plan from the short-swing  liability provisions
of the Federal  securities  laws.  The  February  1997  Amendment  is subject to
stockholder  approval at the 1997 Annual  Meeting,  and no option grants made on
the basis of the February 1997 share increase shall become  exercisable in whole
or in part  unless and until the  February  1997  Amendment  is  approved by the
stockholders.  Should  such  stockholder  approval  not be  obtained at the 1997
Annual Meeting,  then each option grant made pursuant to the February 1997 share
increase shall terminate and cease to remain outstanding,  and no further option
grants  shall  be made  on the  basis  of  that  share  increase.  However,  the
provisions  of the Plan as in  effect  immediately  prior to the  February  1997
Amendment shall  automatically  be reinstated,  and option grants may thereafter
continue  to be made  pursuant to the  reinstated  provisions  of the Plan.  All
option grants made prior to the February 1997 Amendment shall remain outstanding
in  accordance  with the  terms and  conditions  of the  respective  instruments
evidencing  those  options  or  issuances,  and  nothing  in the  February  1997
Amendment  shall be  deemed to modify  or in any way  affect  those  outstanding
options or  issuances.  Subject to the  foregoing  limitations,  options  may be
granted  under  the  Plan at any  time  before  the date  fixed  herein  for the
termination of the Plan.

                  C. The Plan shall  terminate upon the earliest of (i) July 24,

                               SANDISK CORPORATION
                          EMPLOYEE STOCK PURCHASE PLAN

                  AMENDED AND RESTATED AS OF FEBRUARY 10, 1997


       I.         PURPOSE OF THE PLAN

                  This Employee  Stock  Purchase Plan is intended to promote the
interests  of SanDisk  Corporation  by  providing  eligible  employees  with the
opportunity  to  acquire  a  proprietary  interest  in the  Corporation  through
participation in a payroll-deduction based employee stock purchase plan designed
to qualify under Section 423 of the Code.

                  Capitalized  terms herein shall have the meanings  assigned to
such terms in the attached Appendix.

      II.         ADMINISTRATION OF THE PLAN

                  The Plan Administrator  shall have full authority to interpret
and construe any  provision of the Plan and to adopt such rules and  regulations
for  administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423. Decisions of the Plan  Administrator  shall be
final and binding on all parties having an interest in the Plan.

     III.         STOCK SUBJECT TO PLAN

                  A. The stock  purchasable  under  the Plan  shall be shares of
authorized but unissued or reacquired  Common Stock,  including shares of Common
Stock purchased on the open market. The maximum number of shares of Common Stock
which  may be  issued  in the  aggregate  over  the  term of this  Plan  and the
Corporation's  International Employee Stock Purchase Plan shall not exceed Eight
Hundred Eighty-Three Thousand Three Hundred Thirty-Three  (883,333) shares. Such
share  reserve  includes  (i) the initial  share  reserve of 433,333  shares (as
adjusted to reflect the 2:3 split of the Common Stock authorized by the Board on
July  25,  1995)  approved  by the  stockholders  in  August  1996,  and (ii) an
additional 450,000 share increase  authorized by the Board on February 10, 1997,
subject to stockholder  approval at the 1997 Annual Meeting. No shares of Common
Stock  shall be issued  under the Plan on the basis of the  February  1997 share
increase unless that increase is approved by the stockholders at the 1997 Annual
Meeting,  and in no event  shall  more than  674,063  shares of Common  Stock be
issued in the aggregate  under this Plan and the  International  Employee  Stock
Purchase  Plan after  February 28, 1997,  assuming  stockholder  approval of the
February 1997 share increase.

                  B. Should any change be made to the Common  Stock by reason of
any stock  split,  stock  dividend,  recapitalization,  combination  of  shares,
exchange of shares or


<PAGE>


 other change  affecting the outstanding  Common Stock as a
class  without  the   Corporation's   receipt  of   consideration,   appropriate
adjustments  shall be made to (i) the  maximum  number  and class of  securities
issuable in the aggregate under this Plan and the  International  Plan, (ii) the
maximum number and class of securities  purchasable  per  Participant on any one
Purchase  Date and (iii) the  number and class of  securities  and the price per
share in effect under each  outstanding  purchase  right in order to prevent the
dilution or enlargement of benefits thereunder.

      IV.         OFFERING PERIODS

                  A. Shares of Common Stock shall be offered for purchase  under
the Plan through a series of successive  Offering Periods until such time as (i)
the maximum  number of shares of Common Stock  available for issuance  under the
Plan  shall  have  been  purchased  or (ii)  the Plan  shall  have  been  sooner
terminated.

                  B. Each  Offering  Period  (other  than the  Initial  Offering
Period) shall have a duration of six (6) months. Offering Periods shall run from
the first  business  day in February to the last  business day in July each year
and from the first  business day of August each year to the last business day in
January in the  following  year.  However,  the Initial  Offering  Period  shall
commence  at the  Effective  Time  and  terminate  on the last  business  day in
January,  1997.  During the Initial  Offering  Period,  there shall be three (3)
successive  Purchase  Intervals:  the first shall run from the Effective Time to
the last  business  day in January  1996;  the  second  shall run from the first
business day in February  1996 to the last  business  day in July 1996;  and the
last shall run from the first business day in August to the last business day in
January 1997. A Purchase  Date shall occur at the end of each Purchase  Interval
within the  Initial  Offering  Period.  However,  for each  subsequent  Offering
Period,  there shall only be a single Purchase Date coincident with the last day
of that Offering Period.

       V.         ELIGIBILITY

                  A. Only  individuals  who are Eligible  Employees on the start
date of an Offering Period shall be eligible to participate in the Plan for that
Offering  Period.  For  the  Initial  Offering  Period,  the  following  special
eligibility provisions shall be in effect:

                           - Each individual who is an Eligible  Employee at the
         Effective Time may enter the Initial Offering Period at that time or on
         the start date of any subsequent Purchase Interval within that Offering
         Period, provided he or she remains an Eligible Employee on that date.

                           - Each  individual  who  first  becomes  an  Eligible
         Employee after the Effective Time may enter the Initial Offering Period
         on the start  date of any  subsequent  Purchase  Interval  within  that
         Offering  Period,  provided he or she is an  Eligible  Employee on that
         date.

                                       2
<PAGE>



                  B. The date an Eligible  Employee  enters the Offering  Period
shall be designated his or her Entry Date.

                  C.  To  participate  in the  Plan  for a  particular  Offering
Period,  the Eligible  Employee must complete the enrollment forms prescribed by
the Plan  Administrator  (including  a stock  purchase  agreement  and a payroll
deduction  authorization  form) and file such forms with the Plan  Administrator
(or its designate) on or before his or her scheduled Entry Date.

      VI.         PAYROLL DEDUCTIONS

                  A. The payroll  deduction  authorized by the  Participant  for
purposes of acquiring  shares of Common Stock under the Plan may be any multiple
of one percent (1%) of the Cash Compensation paid to the Participant during each
Offering  Period,  up to a maximum of ten percent  (10%).  The deduction rate so
authorized  shall  continue in effect from Offering  Period to Offering  Period,
except to the  extent  such rate is  changed in  accordance  with the  following
guidelines:

                                 (i) The Participant  may, at any time during an
         Offering Period,  reduce his or her rate of payroll deduction to become
         effective as soon as possible  after filing the  appropriate  form with
         the Plan Administrator.  The Participant may not, however,  effect more
         than one (1) such reduction per Offering Period or Purchase Interval.

                                 (ii) The Participant may, prior to the start of
         any new  Offering  Period  or the  start of any new  Purchase  Interval
         within the Initial  Offering  Period,  increase  the rate of his or her
         payroll  deduction  by  filing  the  appropriate  form  with  the  Plan
         Administrator. The new rate (which may not exceed the ten percent (10%)
         maximum)  shall  become  effective  as of the  start  date of the first
         Offering Period or Purchase Interval following the filing of such form.

                  B.  Payroll  deductions  shall  begin  on the  first  pay  day
following  the  Participant's  Entry  Date into the  Offering  Period  and shall
(unless  sooner  terminated  by the  Participant)  continue  through the pay day
ending with or immediately  prior to the last day of that Offering  Period.  The
amounts so collected shall be credited to the  Participant's  book account under
the  Plan,  but no  interest  shall  be paid on the  balance  from  time to time
outstanding in such account.  The amounts  collected from the Participant  shall
not be held in any segregated  account or trust fund and may be commingled  with
the general assets of the Corporation and used for general corporate purposes.

                  C.  Payroll  deductions  shall  automatically  cease  upon the
termination  of  the  Participant's   purchase  right  in  accordance  with  the
provisions of the Plan.

                                       3
<PAGE>



                  D. The  Participant's  acquisition  of Common  Stock under the
Plan on any  Purchase  Date shall  neither  limit nor require the  Participant's
acquisition of Common Stock on any subsequent Purchase Date.

     VII.         PURCHASE RIGHTS

                  A. Grant of Purchase  Right. A Participant  shall be granted a
separate   purchase  right  for  each  Offering   Period  in  which  he  or  she
participates.  The purchase  right shall be granted on the  Participant's  Entry
Date into the Offering Period and shall provide the  Participant  with the right
to  purchase  shares  of Common  Stock  upon the  terms  set  forth  below.  The
Participant  shall execute a stock purchase  agreement  embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

                  Under no circumstances  shall purchase rights be granted under
the Plan to any Eligible  Employee if such individual  would,  immediately after
the grant,  own (within the meaning of Code Section 424(d)) 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
Corporation or any Corporate Affiliate.

                  B. Exercise of the Purchase Right. The purchase right shall be
automatically  exercised on each Purchase Date within the Offering  Period,  and
shares  of  Common  Stock  shall  accordingly  be  purchased  on  behalf  of the
Participant (other than any Participant whose payroll deductions have previously
been refunded in accordance  with the  Termination of Purchase Right  provisions
below) on such  Purchase  Date.  The purchase  shall be effected by applying the
Participant's  payroll  deductions  for  the  Offering  Period  or the  Purchase
Interval to the purchase of whole  shares of Common Stock at the purchase  price
in effect for the Participant for the Purchase Date coincident with the last day
of  that  Offering  Period  or  Purchase  Interval.   All  shares  purchased  on
Participant's  behalf shall be directly deposited into an account maintained for
such Participant at a Corporation-designated brokerage firm.

                  C.  Purchase  Price.  The  purchase  price  per share at which
Common  Stock shall be purchased on the  Participant's  behalf on each  Purchase
Date within the Offering  Period shall be equal to eighty-five  percent (85%) of
the  lower  of (i) the Fair  Market  Value  per  share  of  Common  Stock on the
Participant's Entry Date into that Offering Period or (ii) the Fair Market Value
per share of Common Stock on that Purchase Date.  However,  for each Participant
who joins the  Initial  Offering  Period  after the start  date,  the clause (i)
amount  shall in no event be less than the Fair Market Value per share of Common
Stock on the start date of the Initial Offering Period.

                  D.  Number  of  Purchasable  Shares.  The  number of shares of
Common Stock  purchasable  by a  Participant  on each Purchase Date shall be the
number of whole shares obtained by dividing the Participant's payroll deductions
for the Offering Period or

                                       4
<PAGE>



Purchase  Interval  ending on such date by the purchase  price in effect for the
Participant  for that Purchase  Date.  However,  the maximum number of shares of
Common Stock  purchasable  per  Participant  on any one Purchase  Date shall not
exceed Seven Hundred Fifty (750) shares,  subject to periodic adjustments in the
event of certain changes in the Corporation's capitalization.

                  E.  Excess  Payroll  Deductions.  Any payroll  deductions  not
applied to the purchase of shares of Common  Stock on any Purchase  Date because
they are not  sufficient to purchase a whole share of Common Stock shall be held
for the purchase of Common Stock on the next Purchase Date. However, any payroll
deductions  not  applied  to the  purchase  of  Common  Stock by  reason  of the
limitation on the maximum number of shares purchasable by the Participant on the
Purchase Date shall be promptly refunded.

                  F.  Termination of Purchase  Right.  The following  provisions
shall govern the termination of outstanding purchase rights:

                                 (i) A Participant may, at any time prior to the
         next scheduled Purchase Date, terminate his or her outstanding purchase
         right by filing the appropriate  form with the Plan  Administrator  (or
         its designate),  and no further payroll  deductions  shall be collected
         from the Participant with respect to the terminated purchase right. Any
         payroll  deductions  collected  during the Offering  Period or Purchase
         Interval in which such termination  occurs shall, at the  Participant's
         election, be immediately refunded or held for the purchase of shares on
         the next  scheduled  Purchase  Date. If no such election is made at the
         time such purchase  right is  terminated,  then the payroll  deductions
         collected  with  respect to the  terminated  right shall be refunded as
         soon as possible.

                                 (ii) The  termination  of such  purchase  right
         shall be irrevocable,  and the Participant may not subsequently  rejoin
         the  Offering  Period  for  which  the  terminated  purchase  right was
         granted.  In order to resume  participation in any subsequent  Offering
         Period,  such individual must re-enroll in the Plan (by making a timely
         filing of the prescribed  enrollment forms) on or before the start date
         of that Offering Period.

                                 (iii) Should the Participant cease to remain an
         Eligible Employee for any reason (including death, disability or change
         in status) while his or her purchase  right remains  outstanding,  then
         that  purchase  right  shall  immediately  terminate,  and  all  of the
         Participant's  payroll  deductions for the Offering  Period or Purchase
         Interval in which the purchase right so terminates shall be immediately
         refunded.  However,  should the  Participant  cease to remain in active
         service by reason of an  approved  unpaid  leave of  absence,  then the
         Participant shall have the election,  exercisable up until the last day
         of the  Offering  Period  or  Purchase  Interval  in which  such  leave
         commences,

                                       5
<PAGE>


         to (a) withdraw all the payroll deductions  collected to date on his or
         her behalf for such  Offering  Period or Purchase  Interval or (b) have
         such  funds  held for the  purchase  of  shares  on the next  scheduled
         Purchase  Date.  In  no  event,  however,  shall  any  further  payroll
         deductions be collected on the Participant's  behalf during such leave.
         Upon the  Participant's  return to active  service,  his or her payroll
         deductions  under the Plan  shall  automatically  resume at the rate in
         effect at the time the leave began, provided the Participant returns to
         service prior to the  expiration  date of the Offering  Period in which
         such leave began.

                  G.  Corporate  Transaction.  Each  outstanding  purchase right
shall automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant to
the purchase of whole shares of Common Stock at a purchase price per share equal
to eighty-five percent (85%) of the lower of (i) the Fair Market Value per share
of Common  Stock on the  Participant's  Entry Date into the  Offering  Period in
which such Corporate  Transaction occurs or (ii) the Fair Market Value per share
of  Common  Stock  immediately  prior to the  effective  date of such  Corporate
Transaction.  However,  the  applicable  limitation  on the  number of shares of
Common  Stock  purchasable  per  Participant  shall  continue  to  apply to each
purchase. Should the Corporate Transaction occur in the Initial Offering Period,
then the clause (i) amount above shall not, for any Participant whose Entry Date
into the Initial  Offering  Period is other than the start date of that Offering
Period,  be less than the Fair  Market  Value per share of Common  Stock on such
start date.

                  The Corporation shall use its best efforts to provide at least
ten  (10)-days   prior  written  notice  of  the  occurrence  of  any  Corporate
Transaction,  and Participants shall, following the receipt of such notice, have
the right to terminate their outstanding  purchase rights prior to the effective
date of the Corporate Transaction.

                  H.  Proration of Purchase  Rights.  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 Plan, the Plan Administrator  shall 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,  shall
be refunded.

                  I.  Assignability.  During  the  Participant's  lifetime,  the
purchase right shall be  exercisable  only by the  Participant  and shall not be
assignable or transferable.

                  J. Stockholder Rights. A Participant shall have no stockholder
rights with  respect to the shares  subject to his or her  outstanding  purchase
right until the shares are purchased on the  Participant's  behalf in accordance
with the  provisions  of the Plan and the  Participant  has  become a holder  of
record of the purchased shares.

    VIII.         ACCRUAL LIMITATIONS

                  A. No  Participant  shall be  entitled  to  accrue  rights  to
acquire Common Stock pursuant to any purchase right  outstanding under this Plan
if and to the extent such accrual,  when  aggregated with (i) rights to purchase
Common Stock accrued under any other  purchase right granted under this Plan and
(ii) similar  rights  accrued under other  employee stock purchase plans (within
the meaning of Code Section 423) of the Corporation or any Corporate  Affiliate,
would  otherwise  permit  such  Participant  to purchase  more than  Twenty-Five
Thousand  Dollars  ($25,000)  worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value of such stock on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

                  B. For purposes of applying  such accrual  limitations  to the
purchase  rights granted under this Plan, the following  provisions  shall be in
effect:

                                 (i) The right to  acquire  Common  Stock  under
         each   outstanding   purchase   right  shall  accrue  in  one  or  more
         installments on each Purchase Date within the Offering Period for which
         such right is granted.

                                 (ii) No right to acquire Common Stock under any
         outstanding  purchase right shall accrue to the extent the  Participant
         has  already  accrued  in the same  calendar  year the right to acquire
         Common  Stock  under one (1) or more  other  purchase  rights at a rate
         equal to Twenty-Five  Thousand Dollars  ($25,000) worth of Common Stock
         (determined  on the basis of the Fair Market Value of such stock on the
         date or dates of grant) for each  calendar year such rights were at any
         time outstanding.

                  C. If by  reason of such  accrual  limitations,  the  purchase
right of a Participant  does not accrue for a particular  Offering  Period (or a
particular  Purchase  Interval  within the Initial  Offering  Period),  then the
payroll  deductions  which the Participant  made during that Offering Period (or
Purchase  Interval)  with  respect to such  unaccrued  purchase  right  shall be
promptly refunded.

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

      IX.         EFFECTIVE DATE AND TERM OF THE PLAN

                  A. The  Plan was  adopted  by the  Board on July 25,  1995 and
shall  become  effective  at the  Effective  Time,  provided no purchase  rights
granted under the Plan shall be  exercised,  and no shares of Common Stock shall
be  issued  hereunder,  until  (i) the Plan  shall  have  been  approved  by the
stockholders of the  Corporation  and (ii) the  Corporation  shall have complied
with all applicable  requirements of the 1933 Act (including the registration

                                       7
<PAGE>


of the shares of Common Stock issuable under the Plan on a Form S-8 registration
statement  filed with the  Securities and Exchange  Commission),  all applicable
listing  requirements of any stock exchange (or the Nasdaq National  Market,  if
applicable)  on which the  Common  Stock is  listed  for  trading  and all other
applicable  requirements  established  by law or  regulation.  In the event such
stockholder approval is not obtained, or such compliance is not effected, within
twelve (12) months after the date on which the Plan is adopted by the Board, the
Plan shall  terminate and have no further force or effect and all sums collected
from Participants during the Initial Offering Period shall be refunded.

                  B.  Unless  sooner  terminated  by the  Board,  the Plan shall
terminate upon the earliest of (i) the last business day in July 2005,  (ii) the
date on which all shares  available for issuance  under the Plan shall have been
sold pursuant to purchase  rights  exercised under the Plan or (iii) the date on
which  all  purchase  rights  are  exercised  in  connection  with  a  Corporate
Transaction.  No further  purchase rights shall be granted or exercised,  and no
further  payroll  deductions  shall be collected,  under the Plan following such
termination.

       X.         AMENDMENT OF THE PLAN

                  A. The Board may alter, amend, suspend or discontinue the Plan
at any time to become effective  immediately following the close of any Offering
Period or Purchase Interval. However, the Board may not, without the approval of
the Corporation's stockholders,  (i) materially increase the number of shares of
Common Stock issuable under the Plan or the maximum number of shares purchasable
per Participant on any one Purchase Date, except for permissible  adjustments in
the event of certain changes in the Corporation's capitalization, (ii) alter the
purchase price formula so as to reduce the purchase price payable for the shares
of Common  Stock  purchasable  under the Plan or (iii)  materially  increase the
benefits  accruing  to  Participants  under the Plan or  materially  modify  the
requirements for eligibility to participate in the Plan.

                  B. On February 10, 1997, the Board adopted an amendment to the
Plan to increase  the number of shares of Common Stock  authorized  for issuance
under  this  Plan  and the  International  Employee  Stock  Purchase  Plan by an
additional  450,000  shares in the  aggregate.  This  amendment  is  subject  to
stockholder  approval at the 1997 Annual Meeting, and no shares may be issued on
the basis of the 450,000 share  increase  unless and until the share increase is
approved by the stockholders.  Should such stockholder  approval not be obtained
at the 1997 Annual  Meeting,  then the maximum  number of shares  available  for
subsequent  issuance  in the  aggregate  under  this Plan and the  International
Employee  Stock  Purchase  Plan  shall not  exceed  the  number of shares  which
remained  available  for issuance  immediately  prior to the February 1997 share
increase.
