SANDISK CORPORATION
                          EMPLOYEE STOCK PURCHASE PLAN

                  AMENDED AND RESTATED AS OF DECEMBER 17, 1998


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 One  Million One
Hundred  Eighty-Three  Thousand Three Hundred  Thirty-Three  (1,183,333) 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, (ii) an additional
450,000 share increase authorized by the Board on February 10, 1997 and approved
by the  stockholders at the 1997 Annual Meeting and (iii) an additional  300,000
share  increase  authorized  by the  Board on  December  17,  1998,  subject  to
stockholder approval at the 1999 Annual Meeting. No shares of Common Stock shall
be issued under the Plan on the basis of such 300,000-share increase unless that
increase is approved by the stockholders at the 1999 Annual Meeting. In no event
shall more than 741,455 shares of Common Stock be issued in the aggregate  under
this Plan and the  International  Employee  Stock  Purchase Plan after March 15,
1999.

         B. The number of shares of Common Stock  available  for issuance  under
the combined reserve of this Plan and the International Plan shall automatically
increase on the first  trading day of January each calendar year during the term
of  the  Plan,  beginning  with  calendar  year  2002,  by an  amount  equal  to
forty-three  one hundredths of one percent (0.43%) of the shares of Common Stock
outstanding  on the last  trading day in December of the  immediately  preceding
calendar  year,  but in no event shall any such annual  increase  exceed 150,000
shares.





         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 class of securities issuable in the aggregate
under this Plan and the International Plan, (ii) the maximum number and/or class
of  securities  by which the  combined  share  reserve  under  this Plan and the
International  Plan is to increase each calendar year pursuant to the provisions
of Section III.B,  (iii) the maximum number and class of securities  purchasable
per  Participant  on any one  Purchase  Date and (iv) 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



         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.

         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.


                                       3



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 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.
However,  the  Plan  Administrator  shall  have  the  discretionary   authority,
exercisable  prior to the start of any Offering Period,  to increase or decrease
the  limitation  to be in  effect  for the  number  of  shares  purchasable  per
Participant on the Purchase Date for that Offering Period.


                                       4



         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,   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 (x) within ninety
                  (90) days  following  the  commencement  of such  leave or (y)
                  prior to the  expiration  of any longer  period for which such
                  Participant's  right to  reemployment  with the Corporation is
                  guaranteed by either  statute or contract,  his or her payroll
                  deductions  under the Plan shall  automatically  resume at the
                  rate in  effect  at the  time  the  leave  began,  unless  the
                  Participant  withdraws  from  the  Plan  prior  to  his or her
                  return.   An  individual  who  returns  to  active  employment
                  following a leave of absence  which  exceeds in  duration  the
                  applicable (x) or (y) time period will be treated as a new

                                       5



                  Employee for purposes of subsequent  participation in the Plan
                  and must accordingly re-enroll in the Plan (by making a timely
                  filing of the  prescribed  enrollment  forms) on or before the
                  start date of any new Offering Period or Purchase Interval.

         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.

         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.


                                       6



         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 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.


                                       7



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, 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) 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 was approved by the stockholders at the
1997 Annual Meeting.  On December 17, 1998, the Board adopted  amendments to the
plan to (i)  increase  the  number  of shares of  Common  Stock  authorized  for
issuance in the aggregate under this Plan and the  International  Employee Stock
Purchase  Plan  by an  additional  300,000  shares  and  (ii) to  implement  the
automatic  share  increase  provisions of Section  III.B.  These  amendments are
subject to stockholder approval at the 1999 Annual Meeting, and no shares may be
issued on the basis of the  300,000  share  increase  unless and until the share
increase is approved by the stockholders.  Should such stockholder  approval not
be  obtained  at the 1999  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  300,000-share
