SANDISK CORPORATION

                  1995 NON-EMPLOYEE DIRECTORS STOCK OPTION PLAN

                  AMENDED AND RESTATED AS OF DECEMBER 17, 1998


                                  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.






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 400,000  shares.1
Such share  reserve  includes (i) the initial  share  reserve of 150,000  shares
approved by the  stockholders  in August 1995,  (ii) an additional  50,000 share
increase  authorized  by  the  Board  on  February  10,  1997  and  approved  by
stockholders  at the 1997 Annual  Stockholders  Meeting and (iii) an  additional
200,000 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
become  exercisable  under the Plan on the basis of the 200,000-  share increase
unless that increase is approved by the stockholders at the 1999 Annual Meeting.

         B. The number of shares of Common Stock  available  for issuance  under
the 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 two  tenths of one  percent  (0.2%) 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
75,000 shares.

         C.  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.

         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 maximum  number  and/or class of  securities  by which the share
reserve is to increase each calendar year pursuant to the  provisions of Section
IV.B of this Article One,  (iii) the number and/or class of securities for which
option grants are to be

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

  July 25, 1995.

                                        2



subsequently  made per  Eligible  Director  and (iv) 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.

                                  ARTICLE Two
                              OPTION GRANT PROGRAM

I.       OPTION TERMS

         The provisions of this Article Two reflect the changes to the number of
shares of Common  Stock  subject to the initial and annual  option  grants to be
made to the non-employee  Board members pursuant to the amendment  authorized by
the Board on December  17,  1998,  subject to  stockholder  approval at the 1999
Annual  Meeting.   Stockholder  approval  of  such  amendment  shall  constitute
pre-approval  of each option  grant made on or after the date of the 1999 Annual
Meeting to the non-employee  Board members pursuant to the amended provisions of
this Article Two and the subsequent  exercise of that option in accordance  with
such provisions.

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

         1. Each  Eligible  Director  who is first  elected  or  appointed  as a
non-employee  Board member on or after the date of the 1999 Annual  Stockholders
Meeting shall  automatically be granted, on the date of such initial election or
appointment  (as the case may be), a  Non-Statutory  Option to  purchase  32,000
shares of Common Stock.

         2. On the date of each Annual Stockholders Meeting,  beginning with the
1999 Annual Meeting,  each individual who is to continue to serve as an Eligible
Director  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  8,000 shares of Common  Stock,
provided such individual has served as a non-employee  Board member for at least
six (6) months prior to the date of such Annual Meeting. There shall be no limit
on the number of such  8,000-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


                                       4



         (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.

         (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.


                                       5



         (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).

         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 December
17, 1998 amendment and 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.

                                 ARTICLE Three
                                  MISCELLANEOUS

I.       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 was approved by the
stockholders  at the 1997 Annual  Meeting.  The Plan was amended on December 17,
1998 (the  "December  1998  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  200,000 shares,  (ii) implement the automatic
share  increase  provisions of Section IV.B of Article One,  (iii)  increase the
size of the initial grants to  non-employee  Board members from 16,000 to 32,000
shares  of Common  Stock  and (iv)  increase  the size of the  annual  grants to
non-employee Board members from 4,000 to 8,000 shares of Common Stock. No option
grants  made  on the  basis  of the  200,000-share  increase  authorized  by the
December 1998 Amendment shall become  exercisable in whole or in part unless and
until that amendment is approved by the  stockholders.  Should such  stockholder
approval not be obtained at the 1999 Annual Meeting, then each option grant made
pursuant to the 200,000-share increase authorized by the December 1998 Amendment
shall terminate and cease to remain outstanding,  no further option grants shall
be made on the basis of that share  increase,  and the automatic  share increase
provisions of Section IV.B of Article One shall not be implemented. However, the
provisions  of the Plan as in  effect  immediately  prior to the  December  1998
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 December 1998 Amendment shall remain outstanding
in  accordance  with the  terms and  conditions  of the  respective  instruments
evidencing  those  options  or  issuances,  and  nothing  in the  December  1998
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,  2005,
(ii) the date on which all shares  available  for issuance  under the Plan shall
have been  issued or  cancelled  pursuant  to the  exercise  or  cash-out 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

                                       8



option  grants  and  unvested  stock  issuances  outstanding  on such date shall
thereafter  continue to have force and effect in accordance  with the provisions
of the documents evidencing such grants or issuances.

II.      AMENDMENT OF THE PLAN

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

III.     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.

IV.      REGULATORY APPROVALS

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

V.       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)  and  the   Corporation's
stockholders 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.
