              Notes to Condensed Consolidated Financial Statements


1.     These interim condensed  consolidated  financial statements are unaudited
       but  reflect,  in  the  opinion  of  management,   all  normal  recurring
       adjustments necessary to present fairly the financial position of SanDisk
       Corporation and Subsidiaries (the "Company") as of June 30, 1998, and the
       results of operations  and cash flows for the three and six month periods
       ended June 30,  1998 and 1997.  Because all the  disclosures  required by
       generally accepted accounting principles are not included,  these interim
       condensed consolidated financial statements should be read in conjunction

6.     To preserve its intellectual property rights, the Company believes it may
       be  necessary  to  initiate  litigation  with one or more third  parties,
       including  but not limited to those the Company has  notified of possible
       patent infringement.  In addition, one or more of these parties may bring
       suit against the Company.

       In March 1998,  the Company  filed a complaint in federal  court  against
       Lexar Media, Inc.  ("Lexar") for infringement of a fundamental  flashdisk
       patent.  Lexar has disputed the Company's  claim of patent  infringement,
       claimed SanDisk's patent is invalid or unenforceable and asserted various
       counterclaims including unfair competition,  violation of the Lanham Act,
       patent misuse,  interference with prospective  economic advantage,  trade
       defamation and fraud. SanDisk has denied each of Lexar's counterclaims.

        In July 1998, the federal  district court denied Lexar's request to have
       the case  dismissed  on the  grounds  the  Company  failed to  perform an
       adequate  prefiling  investigation.  As a result,  discovery in the Lexar
       suit will  commence in August  1998.  The Company  intends to  vigorously
       enforce its  patents,  but there can be no assurance  that these  efforts
       will be successful.

       From  time to  time  the  Company  agrees  to  indemnify  certain  of its
       suppliers  and customers for alleged  patent  infringement.  The scope of
       such indemnity varies but may in some instances include

                                     Page 7



       indemnification  for damages and expenses,  including attorneys fees. The
       Company  may from time to time be  engaged in  litigation  as a result of
       such   indemnification   obligations.   Third  party  claims  for  patent
       infringement  are excluded  from coverage  under the Company's  insurance
       policies.  There  can be no  assurance  that  any  future  obligation  to
       indemnify the Company's customers or suppliers,  will not have a material
       adverse effect on the Company's business, financial condition and results
       of operations.

       Any  litigation,  whether as a plaintiff or as a  defendant,  will likely
       result in  significant  expense to the  Company and divert the efforts of
       the Company's  technical and  management  personnel,  whether or not such
       litigation is ultimately determined in favor of the Company. In the event
       of an  adverse  result  in any  such  litigation,  the  Company  could be
       required to pay substantial damages, cease the manufacture,  use and sale
       of  infringing   products,   expend  significant   resources  to  develop
       non-infringing   technology   or  obtain   licenses  to  the   infringing
       technology,  or discontinue  the use of certain  processes.  Accordingly,
       there  can be no  assurance  that any of the  foregoing  matters,  or any
       future  litigation,  will  not  have a  material  adverse  effect  on the
       Company's business, financial condition and results of operations.

7.     The Company  recorded a provision for income taxes at a 36% effective tax
       rate for the first six months of 1998  compared  to a 15%  effective  tax
       rate for the same period of 1997.  The  effective  tax rate for the first
       six months of 1997 was substantially below the federal statutory rate due
       to the utilization of federal and state tax credit carryforwards, Foreign
       Sales  Corporation tax benefits and a reduction in the deferred tax asset
       valuation allowance.

8.     The Company has a credit agreement (the Agreement) with a bank, which was
       renewed  in July  1998.  Under the  provisions  of the  Agreement,  which
       expires in July 1999,  the  Company  may borrow up to $10.0  million on a
       revolving line of credit at the bank's prime interest rate. Amounts under
       the revolving line of credit can be applied to the issuance of letters of
       credit up to the full amount of the credit line.  At June 30, 1998,  $7.2
       million of letters of credit were  outstanding.  In  addition,  under the
       Agreement, the Company also has a $15.0 million foreign exchange contract
       line under which the Company may enter into foreign  exchange  contracts.
       As of June 30,  1998,  $4.4  million  was  outstanding  under the foreign
       exchange contract portion of the line. The Agreement  contains  covenants
       that require the Company to maintain certain  financial ratios and levels
       of net worth.  The Agreement  prohibits the payment of cash  dividends to
       stockholders.

9.     As of  January  1, 1998,  the  Company  adopted  statement  of  Financial
       Accounting  Standards  No.  130  (SFAS  130),  "Reporting   Comprehensive
       Income." SFAS 130  establishes new rules for the reporting and display of
       comprehensive  income and its components;  however,  the adoption of this
       Statement  had no impact on the  Company's  net  income or  stockholders'
       equity.  SFAS 130 requires  unrealized  gains or losses on the  Company's
       available-for-sale  securities,  which  prior to adoption  were  reported
       separately in stockholders' equity, to be included in other comprehensive
       income.

       Accumulated other comprehensive  income, which consists of gains (losses)
       on available-for-sale  securities,  was $187,000 and ($4,000) at June 30,

       No. 133, "Accounting for Derivative  Instruments and Hedging Activities,"
       which is required to be adopted in years  beginning  after June 15, 1999.
       Because of the Company's minimal use of derivatives,  management does not
       anticipate that the adoption of the new statement will have a significant
       effect on earnings or the financial position of the Company.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

         Certain  statements  in this  discussion  and  analysis,  including  in
particular,  the second  paragraph under the discussion of product  revenues and
the  paragraph  discussing  patent  license  and royalty  revenues,  are forward
looking  statements  based on current  expectations and entail various risks and
uncertainties  that could cause actual results to differ  materially  from those
expressed in such forward looking  statements.  Such risks and uncertainties are
discussed  below and in the Company's  Form 10-K for the year ended December 31,
1997 under the heading "Risk Factors".  Readers are cautioned not to place undue
reliance on these forward  looking  statements,  which speak only as of the date
hereof.  The Company  undertakes no  obligation to update these forward  looking
statements to reflect events or  circumstances  occurring after the date hereof.
The  following  discussion  should  be read in  conjunction  with the  Company's
consolidated financial statements and the notes thereto.

Overview

         The  Company  was  founded  in 1988 to develop  and  market  flash data
storage systems.  The Company sells its products to the consumer electronics and
industrial/communications  markets. During the course of 1997, the percentage of
the Company's  product sales  attributable to the consumer  electronics  market,
particularly  sales  of its  CompactFlash  products  for use in  digital  camera
applications,  increased  substantially.  This increase in sales to the consumer
market  resulted in a shift to lower  capacity  products,  which  typically have
lower average selling prices and gross margins than higher capacity products. In
addition,  these products are  frequently  sold into the retail  channel,  which
usually has shorter  customer order  lead-times  than the other channels used by
the Company,  thereby  decreasing the Company's  ability to accurately  forecast
future  production  needs.   Subject  to  continued  market  acceptance  of  its
CompactFlash  products,  the Company  believes  these  products will continue to
represent  a majority  of the  Company's  sales as the  popularity  of  consumer
applications,  including  digital  cameras,  increases.  The percentage of sales
attributable  to orders received and fulfilled in the same quarter has increased
over time and, in  response,  the Company is  continuing  to work to shorten its
manufacturing cycle times.

         The  Company's  operating  results are  affected by a number of factors
including  the  volume of  product  sales,  the  timing of  significant  orders,
competitive  pricing pressures,  the ability of the Company to match supply with
demand,  changes  in product  and  customer  mix,  market  acceptance  of new or
enhanced  versions of the Company's  products,  changes in the channels  through
which  the   Company's   products  are   distributed,   timing  of  new  product
announcements and  introductions by the Company and its competitors,  the timing
of license and royalty  revenues,  fluctuations in product costs, the ability of
the  Company to achieve  manufacturing  efficiencies  with its new and  existing
products,  availability of foundry capacity,  variations in manufacturing  cycle
times,  fluctuations  in  manufacturing  yields and  manufacturing  utilization,
increased research and development  expenses and exchange rate fluctuations.  In
addition,  as the proportion of the Company's  products sold for use in consumer
electronics applications increases, the Company's revenues may become subject to
seasonal  declines  in the first  quarter  of each  year.  See  "Risk  Factors -
Fluctuations  in  Operating  Results",  "-  Increasing  Dependence  on  Consumer
Products" and "- Seasonality."

         Beginning in late 1995, the Company adopted a strategy of licensing its
flash  technology,  including  its patent  portfolio,  to  selected  third party
manufacturers  of flash  products.  To date, the Company has entered into patent
cross-license   agreements  with  six  companies,   and  it  intends  to  pursue
opportunities to enter into additional  licenses.  The Company's current license
agreements provide for the payment of license fees, royalties,  or a combination
thereof,  to the  Company.  The  timing and  amount of these  payments  can vary
substantially from quarter to quarter,  depending on the terms of each agreement
and, in some cases,  the timing of sales of products by the other parties.  As a
result,  license and royalty revenues have fluctuated  significantly in the past
and are likely to continue to fluctuate in the future. Given the relatively high
gross margins  associated with license and royalty  revenues,  gross margins and
net income are likely to  fluctuate  more with  changes in license  and  royalty
revenues than with changes in product revenues.

                                    Page 10




         SanDisk  markets  its  products  using  a  direct  sales  organization,
distributors,  manufacturers' representatives,  private label partners, OEMs and
retailers.  The  Company  expects  that sales  through the retail  channel  will
comprise  an  increasing  share  of total  revenues  in the  future,  and that a
substantial  portion  of its  sales  into  the  retail  channel  will be made to
participants  that will have the right to return  unsold  products.  The Company
recognizes  revenues  from  these  sales when the  products  are sold to the end
customers.

         Historically,  a majority of the Company's sales have been to a limited
number of customers. The Company expects that sales of its products to a limited
number of customers  will continue to account for a  substantial  portion of its
product  revenues for the foreseeable  future.  The Company has also experienced
significant  changes in the  composition  of its customer base from year to year
and  expects  this  pattern to  continue  as market  demand for such  customers'
products fluctuates. The loss of, or significant reduction in purchases by major
customers,  could  have a material  adverse  effect on the  Company's  business,
financial  condition  and results of  operations.  See "Risk  Factors - Customer
Concentration."

         Due to the emerging nature of the Company's markets and certain planned
product transitions, the Company has had difficulty forecasting future inventory
levels  required  to meet  customer  demand.  As a  result  of both  contractual
obligations and manufacturing cycle time, the Company has been required to order
wafers from its foundries  several months in advance of the ultimate shipment of
its products.  Under the Company's wafer supply agreements,  there are limits on
the number of wafers the Company can order and the  Company's  ability to change
that quantity is  restricted.  Accordingly,  the  Company's  ability to react to
significant fluctuations in demand for its products is limited. As a result, the
Company has not been able to match its purchases of wafers to specific  customer
orders and  therefore  the  Company  has from time to time taken write downs for
potential  excess  inventory  purchased prior to the receipt of customer orders.
Also,  the  Company  has from time to time taken  write  downs of  inventory  to
reflect a lower of cost or market valuation.  The Company most recently recorded
such a write down in the  second  quarter of 1998.  These  adjustments  decrease
gross margins in the quarter reported and have resulted, and could in the future
result,  in  fluctuations  in gross margins on a quarter to quarter  basis.  See
"Risk Factors - Fluctuations in Operating Results."

         Export sales are an important part of the Company's  business.  While a
majority of the  Company's  revenues  from sales to Asian  countries are derived
from OEM  customers  who plan to export their  products to countries  outside of
Asia,  the Asian  economic  crisis has and may continue to adversely  effect the
Company's  revenues to the extent that demand for the Company's products in Asia
declines.  Given the recent economic conditions in Asia and the weakness of many
Asian currencies  relative to the United States dollar,  the Company's  products
are and may continue to be relatively more expensive in Asia, which could result
in a decrease in the  Company's  sales in that  region.  The Company has and may
continue to  experience  pressure on its gross  margins as a result of increased
price competition from Asian competitors.  While most of the Company's sales are
denominated in U.S. Dollars,  the Company invoices certain Japanese customers in
Japanese Yen and is subject to exchange rate fluctuations on these transactions.
To date,  a portion of the  Company's  purchases of wafers,  which  constitute a
significant  part of its cost of goods sold,  have been  denominated in Japanese
Yen. While this percentage has been decreasing,  exchange rate  fluctuations can
affect the Company's  business,  financial  condition and results of operations.
See "Risk Factors - Risks Associated with International Operations."

         For  the  foreseeable   future,   the  Company  expects  to  realize  a
significant  portion of its revenues from recently  introduced and new products.
Typically  new  products  initially  have lower gross  margins  than more mature
products   because  the   manufacturing   yields  are  lower  at  the  start  of
manufacturing each successive  product  generation.  In addition,  manufacturing
yields are generally  lower at the start of  manufacturing  any product at a new
foundry, such as USIC and NEC. As a result of these factors, the Company expects
that  product  gross  margins  may  decline  in the near  term  from the  levels
experienced  in 1997,  and product  gross  margins are expected to be subject to
fluctuation for the foreseeable future. Moreover, there can be no assurance that
such products or processes will be successfully developed by the

                                    Page 11



Company or that development of such processes will lower manufacturing costs. In
addition,  the Company  anticipates that price  competition will increase in the
future,  which will likely result in decreased  average selling prices and lower
gross margins. See "Risk Factors -Manufacturing Yields" and "- Declining Average
Sales Prices."

         The Company is aware of problems  associated  with computer  systems as
the year 2000  approaches.  Year 2000 problems are the result of common computer
programming techniques that result in systems that do not function properly when
manipulating  dates later than December 31, 1999.  The issue is complex and wide
ranging.  The problem may affect transaction  processing  computer  applications
used by the Company for accounting,  distribution,  manufacturing, and planning.
The problem may also affect embedded systems such as building  security systems,
machine controllers and production test equipment. Year 2000 problems with these
systems may affect the ability or efficiency  with which the company can perform
many  significant  functions,  including  but not limited to: order  processing,
material  planning,  product assembly,  product test,  invoicing,  and financial
reporting.  In  addition,  the  problem may affect the  computer  systems of the
Company's  suppliers  and  customers,  disrupting  their  operations.  Year 2000
problems with the Company's  business  partners may impact the Company's sources
of supply and demand.

         The  Company has  established  a year 2000 Risk  Management  program to
assess the impact of the year 2000 issue on SanDisk, and coordinate  remediation
activities.  The Company is in the process of certifying  that it's products are
year 2000  compliant.  Preliminary  product  testing has  uncovered no Year 2000
problems in the  Company's  products.  Preliminary  investigation  into  product
design,  specifically firmware,  microcode, and software developer tool kits has
uncovered no design assumptions or application programming interfaces that would
cause  year  2000  problems.  The  Company  expects  to  compete  the year  2000
compliance testing of its products in the third quarter of 1998.

         The  year  2000  compliance  assessment  of  the  Company's  management
information  system is complete,  and remediation is well underway.  The Company
currently  uses a  commercially  available  fully  integrated  MRP II (Materials
Requirement  Planning and Accounting  system)  software  application that is not
year 2000  compliant.  This  system is used for  Accounting,  Order  Processing,
Planning, Inventory Control, Shop Floor Control and Distribution. This system is
now being  replaced with a commercial  system that is year 2000  compliant.  The
replacement project is expected to be completed in 1998.

         The  assessment  and  remediation  of year 2000  problems  in  tertiary
business  information  systems  is  on-going.  Well  over  90% of the  company's
investment  in  desktop  PC  hardware  is known to be year 2000  compliant.  The
majority of the software  used on these  systems and network  servers are recent
versions of vendor supported,  commercially available products.  Upgrading these
applications  as year 2000  compliant  patches are  released  by the  respective
vendors has not been a significant burden on the company.

         The  assessment  and  remediation  of year 2000  problems  in  computer
systems used for facilities control,  machine control, and manufacturing testing
is on-going. The most significant year 2000 issue in this area has been found to
be related to older wafer test  equipment.  This equipment is not expected to be
in use in the year 2000. The Company is phasing in new year 2000 compliant wafer
test equipment in conjunction  with the introduction of new generations of flash
memory.

         The cost of the Year 2000 project  related to upgrading  the  Company's
core  management  information  system  is  estimated  to be  approximately  $1.0
million.  The Company has  capitalized  approximately  $400,000  for the cost of
purchased   software  and  hardware.   The  Company   estimates  it  will  incur
approximately $350,000 of consulting expenses over the next few quarters related
to the  implementation of its new information  system.  The additional  expenses
related to the management of the year 2000 compliance program and completing the
assessment  of the Company's  internal and external  risks is not expected to be
material to the Company's quarterly operating results.

         The costs and time  schedule  for the Year 2000 problem  abatement  are
based  on  management's  best  estimates  for  the  implementation  of  its  new
management information system and year 2000 problems

                                    Page 12



uncovered to date. These estimates were derived utilizing numerous  assumptions,
including  that  the  most   significant  Year  2000  risks  have  already  been
identified,  that certain  resources  will continue to be available,  that third
party  plans will be  fulfilled,  and other  factors.  However,  there can be no
guarantee  that these  estimates will be achieved or that the  anticipated  time
schedule  will be met and actual  results  could  differ  materially  from those
anticipated.

         Specific  contingency  plans for systems that pose  significant risk to
on-going operations are being developed under the auspices of the Company's year
2000  Risk  Management  program.  If the  Company  is  unable  to  complete  the
replacement of its core  management  information  system in a timely manner,  an
alternative  plan has been developed.  This plan consists of applying  available
vendor  supplied  software  patches to the existing  system.  The costs and time
involved to  complete  this  alternative  are  expected  to be  minimal.  Should
previously  undetected  Year  2000  problems  be found in other  systems,  these
systems will either be upgraded, replaced, turned off, or operated in place with
manual  procedures  to  compensate  for their  deficiencies.  While the  Company
believes  that these  alternative  plans would be adequate to meet the Company's
needs without  materially  impacting its  operations,  there can be no assurance
that such  alternatives  would be successful  or that the  Company's  results of
operations  would  not  be  materially  adversely  affected  by the  delays  and
inefficiencies inherent in conducting operations in this manner.

         There may be  additional  Year 2000 problems that are as yet unknown to
the Company  and for which  remediation  plans have not yet been made.  Any such
year 2000  compliance  problem  of  either  the  Company,  or its  suppliers  or
customers could materially  adversely affect the Company's business,  results of
operations,  financial condition, and prospects.  There can be no assurance that
the Company's  insurance will cover losses from business  interruptions  arising
from year 2000 problems of the Company or its suppliers.

Results of Operations

         Product Revenues.  SanDisk's product revenues were $23.5 million in the
second quarter of 1998, down $0.4 million or 2% from the second quarter of 1997.
Product revenues for the first half of 1998 were $48.9 million,  up $6.8 million
or 16% from the same  period in 1997.  During  the  three and six month  periods
ended June 30, 1998, units shipped increased 17% and 42%, respectively, from the
same periods of 1997. In the second  quarter of 1998,  the trend toward sales of
higher  capacity  cards  continued with the average  megabyte  capacity per unit
increasing  56% from the same  period of the prior  year.  Due to the decline in
average  selling  prices,  the average  selling  price per  megabyte of capacity
declined  by 50% over this  period.  CompactFlash  average  selling  prices have
eroded more quickly than anticipated due to increased price competition and weak
demand.  The Company  anticipates that  CompactFlash and other small form factor
products  will  continue to represent the major portion of its sales as consumer
applications  such  as  digital  cameras  become  more  popular.  Due  to  price
sensitivity  and intense  competition  in the  consumer  market,  sales of these
products  generally have lower average selling prices and gross margins than the
Company's higher capacity FlashDisk and FlashDrive products. The mix of products
sold varies from  quarter to quarter and may vary in the future,  affecting  the
Company's overall average selling prices and gross margins.

         Sales to Japan  declined 20% in the second  quarter of 1998 compared to
the same period in 1997 due to the to the  economic  recession  in Japan and the
Company's transition to a direct sales model from the use of distributors in the
retail channel in Japan.  The Company  continues to experience  limited bookings
visibility,  particularly  in  Japan.  More  than  one  half  of  the  Company's
anticipated  quarterly  revenues continue to be turns business,  orders received
and fulfilled in the same quarter, with customers demanding short lead times and
quick delivery schedules, thus capitalizing on the current market conditions and
aggressive pricing environment.  Due to a number of factors described herein and
in "Risk  Factors,"  the Company's  ability to adjust its operating  expenses is
limited  in the short  term.  As a result,  if product  revenues  are lower than
anticipated, the Company's results of operations will be adversely affected. See

                                    Page 13



"Risk  Factors-Fluctuations  in Operating  Results",  "- Risks  Associated  with
International Operations" and "Seasonality."

         While  SanDisk  has been  successful  winning  design-ins  for many new
applications,  it  generally  takes  several  quarters  for these  new  customer
products to reach the market.  It is  difficult to predict the timing of related
new product  introductions and future sales volumes from these design-ins as the
success of the customers'  products is uncertain.  There can be no assurance the
applications  will be  developed  and  marketed  successfully  or at all. As new
markets  develop,  competition is expected to increase,  which will likely cause
average  selling  prices to  decline  further  and may cause  gross  margins  to
decline.

         Export sales  represented 46% of product revenues for the three and six
month periods ended June 30, 1998 compared with 52% and 47%,  respectively,  for
the same periods of the previous year. The Company expects  international  sales
to continue to represent a  significant  portion of revenues.  The Company's top
ten customers  represented  64% of product revenue in the second quarter of 1998
compared to 67% for the same period in 1997. The Company expects that sales to a
limited number of customers will continue to represent a substantial  portion of
its revenues for the foreseeable future.

         License  and  Royalty  Revenues.  The Company  currently  earns  patent
licenses and royalty revenues under six cross license agreements,  with Hitachi,
Intel,  Samsung,  Sharp,  Silicon Storage Technology,  Inc. ("SST") and Toshiba.
License and  royalty  revenue  from patent  cross  license  agreements  was $7.9
million in the second  quarter of 1998, up $4.5 million from $3.4 million in the
same period of 1997 primarily due to license and royalty  revenues  earned under
agreements with Hitachi, Toshiba and Sharp which were entered into in the second
half of 1997.  In the  first  half of 1998,  revenue  from  patent  license  and
royalties  was $16.6  million,  up $9.9  million  from the same  period of 1997.
Revenues from patent  licenses and royalties  increased to 25% of total revenues
in the  three  and six  month  periods  ended  June  30,  1998  from 13% and 14%
respectively,  for the same periods of the previous year. The Company  currently
expects that revenues from patent licenses and royalties will be in the range of
$7.5 to $8.0  million in the third  quarter of 1998 due to the timing of revenue
recognition under the various agreements.

         Gross Profits.  In the second quarter of 1998, gross profits were $10.8
million or 34% of total  revenues,  down  slightly  from $11.0 million or 40% of
total revenues for the same period of 1997.  Gross profits for the first half of
1998 were $27.1  million or 41% of total  revenues  compared to $19.5 million or
40% of total  revenues for the same period in the previous  year.  The growth in
overall  gross  profits  for the first  half of 1998 was due to an  increase  in
license and royalty  revenue.  Product  gross  margins  decreased  to 12% in the
second quarter of 1998 compared to 32% for the same period of 1997. The decrease
was primarily due to the decline in average selling  prices.  A lower of cost or
market  inventory  write down also  contributed to the decline in gross margins.
The  Company  expects  to  complete  the  transition  from  32Mbit,  0.4  micron
technology to the more cost effective  64Mbit,  0.35 micron technology and begin
shipment of its 80Mbit D2 flash  products  in the second  half of 1998.  If this
transition is  successful,  the Company  expects gross margins to recover to the
low 20% range over this period.  While the Company has ongoing efforts to reduce
manufacturing  costs,  there can be no assurance that these cost reductions will
be  adequate  to  offset  average  selling  price  declines  due to  anticipated
increased competition.

         Research and  Development.  Research and development  expenses  consist
principally of salaries and payroll related  expenses for design and development
engineers,  prototype supplies and contract  services.  Research and development
expenses increased $1.4 million or 45% in the second quarter of 1998 compared to
the same  period in 1997.  In the first half of 1998  research  and  development
expenses  increased  $2.7  million  compared  to the first  half of 1997.  These
increases  were  primarily  due to an increase in salaries  and payroll  related
expenses  associated  with  additional  personnel,   increased  project  related
expenses and increased depreciation due to capital equipment additions. Research
and  development  expenses  represented  14% of total  revenues  for the  second
quarter of 1998 compared to 11% for the same period in 1997. The Company expects
research and development expenses to continue to increase in absolute dollars to
support the  development of new  generations of flash data storage  products and
the addition of new foundries to manufacture the Company's products.

                                    Page 14




         Sales and Marketing.  Sales and marketing expenses include salaries and
payroll  related  expenses,  sales  commissions  and  travel  expenses  for  the
Company's  sales,  marketing,  customer  service  and  applications  engineering
personnel. These expenses also include other selling and marketing expenses such
as  independent  manufacturer's  representative  commissions,   advertising  and
tradeshow  expenses.  Sales and marketing expenses increased $1.3 million or 43%
in the second  quarter of 1998 compared to the same period in 1997. In the first
half of 1998,  sales and marketing  expenses  increased $2.7 million compared to
the  first  half of  1997.  These  increases  were  primarily  due to  increased
marketing and sales  expenses  related to the  development of the retail channel
for the Company's products. An increase in salaries and payroll related expenses
associated  with  additional  personnel also  contributed to the increase in the
first  half of 1998.  Sales  and  marketing  expenses  represented  14% of total
revenues  in the second  quarter of 1998  compared to 11% for the same period of
1997. The Company  expects sales and marketing  expenses to increase in absolute
dollars as sales of its  products  grow and it  continues  to develop the retail
channel for its products both domestically and internationally.

         General and Administrative. General and administrative expenses include
the  cost  of the  Company's  finance,  information  systems,  human  resources,
shareholder  relations,   legal  and  administrative   functions.   General  and
administrative  expenses  increased $0.2 million or 12% in the second quarter of
1998 compared to the same period of 1997. In the first half of 1998, general and
administrative expenses increased $0.8 million or 29% compared to the first half
of 1997.  These  increases were primarily due to increased  salaries and payroll
related  expenses  associated  with additional  personnel and higher  consulting
expenses  related  to  the   implementation  of  the  Company's  new  management
information system. General and administrative  expenses represented 5% of total
revenues  in the second  quarter of 1998  compared  to 6% for the same period in
1997. The Company  expects  general and  administrative  expenses to increase in
absolute  dollars as these  functions  grow to support the overall growth of the
Company.  General and administrative  expenses could also increase substantially
in the  future in  connection  with the  Company's  efforts to defend its patent
portfolio. See "Risk Factors-Patents Proprietary Rights and Related Litigation."

         Interest  and  Other  Income,  Net.  Interest  and other  income,  net,
increased  $324,000 in the second quarter of 1998 compared to the same period of
1997. This increase was primarily due to higher investment  balances as a result
of the  investment  of proceeds  from the sale of common stock in the  Company's
November 1997 follow on public offering.

         Provision for Income Taxes. The Company recorded a provision for income
taxes at a 36% effective tax rate for the first six months of 1998 compared to a
15% effective  tax rate for the same period of 1997.  The effective tax rate for
the first six months of 1997 was substantially  below the federal statutory rate
due to the  utilization of federal and state tax credit  carryforwards,  foreign
sales  corporation  tax  benefits  and a  reduction  in the  deferred  tax asset
valuation  allowance.  The Company's  1998  effective tax rate is  substantially
higher than its 1997 rate due to the  utilization  of all remaining  federal and
state tax credit carryforwards in 1997.

Liquidity and Capital Resources

         As of June 30, 1998, the Company had working capital of $141.5 million,
which included $13.5 million in cash and cash  equivalents and $118.2 million in
short  term  investments.  The  Company  has a line of  credit  facility  with a
commercial  bank under which it can borrow up to $10 million at the bank's prime
rate.  This line of credit  facility  expires in July 1999. As of June 30, 1998,
the Company had $4.4 million  committed under the foreign  exchange  facility of
the line of credit for Yen forward  exchange  contracts that mature in September
of 1998. The Agreement  contains  covenants that require the Company to maintain
certain  financial  ratios and levels of net worth, and prohibits the payment of
cash dividends to stockholders.

         Operating  activities  used $1.7  million of cash  during the first six
months of 1998 primarily due to a decline in current liabilities and an increase
in inventories. Investing activities used $6.9 million of cash

                                    Page 15



in the first six months of 1998 and included net  purchases  of  investments  of
$4.0 million and $2.9 million of capital equipment  purchases.  During the first
six months of 1998, financing activities provided $1.2 million of cash primarily
from the sale of common  stock under the SanDisk  employee  stock  purchase  and
stock option plans.

         Depending  on the demand for the  Company's  products,  the Company may
decide to make  investments,  which could be  substantial,  in assembly and test
manufacturing  equipment  or foundry  capacity  to support  its  business in the
future.  Management believes the existing cash and cash equivalents,  short term
investments  and  available  line  of  credit,  together  with  cash  flow  from
operations,  will be  sufficient  to meet the  Company's  currently  anticipated
working  capital  and  capital  expenditure  requirements  for at least the next
twelve months.

Impact of Currency Exchange Rates

         The Company  currently  purchases wafers from Matsushita under purchase
contracts  denominated  in yen. A portion  of the  Company's  revenues  are also
denominated in yen.  Foreign exchange  exposures  arising from the Company's yen
denominated  commitments and related  accounts  payable are offset to the extent
the Company has yen denominated  accounts  receivable and cash balances.  To the
extent such foreign exchange  exposures are not offset,  the Company enters into
foreign exchange forward  contracts to hedge against changes in foreign currency
exchange  rates.  At June 30,  1998,  there  were $4.4  million  in Yen  forward
contracts  outstanding.  Future exchange rate fluctuations could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.


Risk Factors

         Fluctuations in Operating  Results.  SanDisk's  operating  results have
been and are  expected  to  continue  to be,  subject  to  quarterly  and annual
fluctuations due to a variety of factors. The principal factors that have caused
the Company's  operating  results to fluctuate in the past several  quarters and
may cause the  Company's  operating  results  to  fluctuate  in the  future  are
unpredictable  demand for the  Company's  products,  declining  average  selling
prices, the economic recession in Japan and the seasonality in sales of products
for consumer  electronics  applications.  For  example,  the  Company's  product
revenues  declined in the first and second quarters of 1998 due to lower average
selling prices, a decline in sales to Japan and seasonal factors.

         The Company must order silicon wafers from its foundries several months
prior to the date such  wafers are  needed.  If the  Company  overestimates  the
number of silicon  wafers it needs to fill product orders and as a result builds
excess  inventories,  gross  margins and  operating  results will be  materially
adversely  affected.  For example,  in the second  quarter of 1998 product gross
margins  declined to 12% from 30% in the  previous  quarter  partially  due to a
lower of cost or market write down of inventory.  Because the Company is selling
CompactFlash,  its largest volume product,  into an emerging consumer market and
is unable to accurately  forecast future sales, there will be a material adverse
effect on the  Company's  operating  results if sales  fall below the  Company's
expectations  in a  particular  quarter  and the Company is unable to reduce its
operating expenses. The portion of the Company's quarterly sales attributable to
orders  received and fulfilled in the same quarter  ("turns  business")  remains
higher than 50% and product order backlog fluctuates  substantially from quarter
to quarter. See "Seasonality" and "Dependence on Third Party Foundries."

         Other  factors  affecting  the  Company's  operating  results and gross
margins include the volume of product sales,  competitive pricing pressures, the
ability of the  Company to match  supply  with  demand,  changes in product  and
customer mix,  market  acceptance  of new or enhanced  versions of the Company's
products,  changes in the  channels  through  which the  Company's  products are
distributed,  timing  of new  product  announcements  and  introductions  by the
Company  and its  competitors,  the  timing  of  license  and  royalty  revenue,
fluctuations in product costs, availability of foundry capacity, variations in

                                    Page 16



manufacturing cycle time, fluctuations in manufacturing yields and manufacturing
utilization,  the ability of the Company to achieve  manufacturing  efficiencies
with its new and existing products, increased research and development expenses,
exchange rate fluctuations and changes in general economic conditions, including
economic  conditions in Asia. All of these factors are difficult to forecast and
these or other factors can materially  affect the Company's  quarterly or annual
operating results or gross margins.

         The Company has increased its expense levels to support its anticipated
growth,  including  expenses  associated  with the  expansion  of the  Company's
in-house  assembly  and test  operations.  The  Company  expects to  continue to
increase  its  operating  expenses  by hiring  additional  personnel  to support
expected growth in sales unit volumes, increased marketing and sales efforts and
accelerated research and development activities. If the Company does not achieve
increased  levels  of  revenues  commensurate  with  these  increased  levels of
operating  expenses,  or if the Company's  revenues  decrease or do not meet the
Company's   expectations  for  a  particular  period,  the  Company's  business,
financial  condition  and results of  operations  will be  materially  adversely
affected.

         The mix of the  Company's  products sold varies from quarter to quarter
and will vary in the future,  affecting the Company's  overall  average  selling
prices and gross margins. The Company's CompactFlash  products,  which currently
represent a significant  portion of the Company's product  revenues,  have lower
average  selling  prices and gross  margins than the Company's  higher  capacity
FlashDisk  and  FlashDrive   products.   The  Company   expects  that  sales  of
CompactFlash  products  will  represent  a  significant  percentage  of  product
revenues as consumer  applications  such as digital cameras become more popular.
This  dependence  on  CompactFlash  sales,  coupled  with lower  pricing  due to
competition,  has caused and is expected to  continue to cause  average  selling
prices to decline,  sometimes at a faster rate than cost reductions  implemented
by the Company.

         The Company has  adopted a strategy of  cross-licensing  its patents to
other  manufacturers  of flash products.  Under such  arrangements,  the Company
earns license fees and royalties on terms that are individually negotiated.  The
timing of recognition  of revenues from these  payments  depends on the terms of
each  contract,  and, in some cases,  on the timing of product  shipments by the
third  parties.  As  a  result,  license  and  royalty  revenue  has  fluctuated
significantly in the past and may fluctuate in the future.  Given the relatively
high gross margins  associated with license and royalty  revenue,  gross margins
and net income are likely to fluctuate  more with changes in license and royalty
revenue than with changes in product revenue.

         Dependence on Emerging Markets and New Products.  The Company's success
depends to a significant extent upon the development of emerging markets and new
applications  for flash  data  storage  systems,  as well as on its  ability  to
introduce commercially  attractive and competitively priced products on a timely
basis. The Company believes that continued significant expenditures for research
and  development  will be  required in the future.  In  particular,  the Company
intends to develop new products with increased  memory  capacity at a lower cost
per  megabyte,  which the Company  believes  will be essential to its ability to
remain  competitive.  In November 1997,  the Company  introduced a new removable
storage card product family, the MultiMediaCard ("MMC"). MMC is targeted for the
emerging  markets  for  mobile  smart  phones,   advanced  pagers  and  consumer
multimedia  devices.  MMC will initially be offered in storage capacities of 4MB
and 8MB.  The Company  does not expect to generate  material  revenues  from MMC
sales in 1998.  There can be no  assurance  that the Company  will  successfully
develop any of these new products,  that new  applications  or markets for flash
data storage will develop as expected by the Company, that prospective customers
developing products for any such markets will design the Company's products into
their products and  successfully  introduce  such products,  or that products or
technologies  developed  by others  will not render the  Company's  products  or
technologies  obsolete or  noncompetitive.  The failure of new  applications  or
markets to develop or the  failure of the  Company's  products to be accepted by
the market  would  have a material  adverse  effect on the  Company's  business,
financial condition and results of operations.

 
                                    Page 17



         Increasing  Dependence on Consumer  Products.  Product revenues derived
from  sales of  products  for  consumer  electronics  applications,  principally
digital  cameras,  have  increased  significantly  and in 1997  represented  the
largest portion of product revenues and units shipped. The Company expects sales
of products for consumer applications to continue to represent the major portion
of  product  revenues  in 1998.  There can be no  assurance,  however,  that the
Company  will  achieve  large scale  market  acceptance  for its products in the
consumer  electronics  market.  The Company  anticipates  that products sold for
consumer  applications will generally  encounter intense competition and will be
more price  sensitive  than  products  sold into its other  target  markets.  In
addition,  consumer  markets  require  larger  expenditures  for  marketing  and
promotion to establish brand name recognition and preference.

         Consumer  markets are more likely to experience  seasonality  of sales,
with potential  declines in sales activity during the first quarter of any year.
Because of the large number of OEMs entering the digital  camera  market,  it is
likely  that not all of these  manufacturers  will be  successful  in  achieving
market  acceptance  of  their  products.  If  SanDisk's  OEM  customers  are not
successful in this market,  such OEM customers  may have excess  inventories  of
CompactFlash products, which may preclude follow-on orders or result in sales of
their  CompactFlash  inventories  in the open market.  The market  acceptance of
digital  cameras  that use  CompactFlash  has been slower than  expected and the
number of  companies  supplying  CompactFlash  has  increased,  causing  average
selling  prices and product  gross margins to decline at a rapid rate. If market
acceptance of digital cameras that use CompactFlash  continues to be slower than
expected,  or if the market for CompactFlash becomes saturated,  the Company may
encounter  reduced demand for CompactFlash  products,  declining average selling
prices or product  returns,  any of which  would  have an adverse  effect on the
Company's results of operations.

         The Company  anticipates that a greater  proportion of its sales to the
consumer  electronics market will be made through  distributors and to retailers
than  is the  case  with  the  industrial/communications  market.  This  will be
particularly  true if the level of  after-market  sales of flash memory products
increases. The Company is currently expending significant resources developing a
retail sales channel.  The  expenditures  associated  with this  development are
likely to precede the  realization  of  significant  sales through this channel.
Moreover,  the Company has no prior  experience in the development or management
of the retail channel or sales through such channel. In addition,  a significant
portion of retail sales for consumer  applications  will be made to distributors
and retail chains,  which typically  maintain rights to return unsold inventory.
As a result,  the Company does not  recognize  revenues on sales to this channel
until after the products have been sold to end users.  If the  Company's  retail
customers are not successful in this market,  there could be substantial product
returns to the Company.  The inability to  successfully  develop and effectively
manage the retail  sales  channel  could have a material  adverse  effect on the
Company's business, financial condition and results of operations.

         Seasonality.  The  Company has  experienced  and expects to continue to
experience  seasonality  in its  product  sales.  A  significant  portion of the
Company's  product revenues are derived from the sale of CompactFlash  products,
which are sold principally for consumer electronics  applications.  As a result,
the  Company's  product  sales  have been and are  expected  to be  impacted  by
seasonal purchasing patterns,  with higher sales in the second half of each year
as  compared to the first half of each such year.  In the past,  the Company has
experienced  a reduction in order  quantities in the first quarter from Japanese
OEM  customers,  reflecting  the fact that most  customers in Japan operate on a
fiscal year ending in March and prefer to delay purchases until the beginning of
their next fiscal year. In the first quarter of 1998,  product revenues declined
24% from the level in the fourth quarter of 1997 due to these  seasonal  factors
and the Asian economic crisis

         Competition.  The flash  data  storage  markets  in which  the  Company
competes are characterized by intense competition,  rapid technological  change,
evolving industry standards,  declining average selling prices and rapid product
obsolescence.   The  Company's  competitors  include  many  large  domestic  and
international   companies  that  have  greater   access  to  foundry   capacity,
substantially  greater  financial,  technical,  marketing  and other  resources,
broader product lines and longer standing  relationships with customers than the
Company. The Company's primary competitors include flash chip producers such as

                                    Page 18



Advanced  Micro  Devices,  Inc.  ("AMD"),   Hitachi  Ltd.   ("Hitachi"),   Intel
Corporation ("Intel"), Micron Technology, Inc. ("Micron"), Mitsubishi Electronic
Corporation ("Mitsubishi"),  Samsung Electronics Company Ltd. ("Samsung"), Sharp
Electronics  Corporation  ("Sharp") and Toshiba Corporation  ("Toshiba"),  other
companies using data storage  techniques such as socket flash,  linear flash and
system flash  components,  as well as package or card  assemblers  such as Lexar
Media, Inc. ("Lexar"),  M-Systems,  Inc.  ("M-Systems"),  Simple Technology Inc.
("Simple"), SMART Modular Technologies, Inc. ("Smart Modular"), Sony Corporation
("Sony"),  Kingston,  TDK, Matsushita Battery, Inc.  ("Matsushita  Battery") and
Viking  Components,  Inc.  that  combine  controllers  and  flash  memory  chips
developed  by others into flash  storage  cards.  Several  companies,  including
Hitachi,  Lexar,  Mitsubishi and Micron have been certified by the  CompactFlash
Association to  manufacture  and sell their own brand of  CompactFlash,  and the
Company believes that other  manufacturers will enter the CompactFlash market in
the future.  Competing  products promoting industry standards that are different
from  SanDisk's  CompactFlash  product have been  announced,  including  Intel's
Miniature  Card,  Toshiba's  Smart Media  (Solid-State  Floppy Disk Card),  Sony
Corporation's  Memory Stick, and Matsushita  Battery's recently  introduced Mega
Storage  cards.  A manufacturer  of digital  cameras that  designs-in any one of
these alternative  competing  standards will eliminate  CompactFlash from use in
its product,  as each  competing  standard is  mechanically  and  electronically
incompatible with CompactFlash. In addition, in the third quarter of 1997, Intel
announced a 64Mbit flash chip based on its multilevel cell flash.  The Company's
double  density  flash  ("D2  flash")  and  Intel's  multilevel  cell  flash are
competing  technological  innovations that allow each flash memory cell to store
two bits of  information  instead  of the  traditional  single bit stored by the
industry  standard  flash  technology.  In  November  1997,  Iomega  Corporation
("Iomega") announced its Clik drive, a miniaturized,  mechanical, removable disk
drive that  Iomega  claims  will  compete  directly  with  SanDisk's  flash card
products.

         In the first and second quarters of 1998,  Sony's Mavica digital camera
captured  approximately  40% of the US market for digital  cameras  according to
independent  industry analysts.  The Mavica uses a standard floppy disk to store
digital images and therefore uses no CompactFlash (or any other flash) cards. If
other  manufacturers  adopt the Mavica  format and it becomes  the new  "defacto
standard",  this will  significantly  reduce the Company's  sales  prospects for
CompactFlash  cards.  The  Company's  MMC  products  are  expected to face stiff
competition from Toshiba's SmartMedia flash cards and Sony's flash Memory Stick.
Sony  announced  its  intention  to begin  shipments  of the Memory Stick in the
fourth  quarter of 1998.  Although the Memory Stick is  proprietary to Sony, its
possible  adoption and  widespread use in future  products may adversely  impact
future sales of the Company's MMC and CompactFlash products.

         The Company expects competition to increase in the future from existing
competitors  and from other  companies that may enter the Company's  existing or
future  markets with similar or alternative  data storage  solutions that may be
less costly or provide additional features. Due to the high price sensitivity in
the  market  for  consumer  products,  aggressive  price  competition  has  been
experienced for these  applications.  Such  competition is expected to result in
lower gross  margins in the future,  if the  Company's  average  selling  prices
decrease faster than its costs and could result in lost sales.

         The  Company's  ability  to  compete  in the  Japanese  market  against
Japanese  flash card  suppliers  has been impacted by the weak Yen. If the Yen's
decline  against the dollar  continues  unchecked the Company's  sales and gross
margins in Japan will be adversely affected.

         The Company  has entered  into  patent  cross-license  agreements  with
Hitachi, Intel, Samsung, Sharp Toshiba, and SST pursuant to which each party may
manufacture and sell products that incorporate  technology  covered by the other
party's  patents related to flash memory  devices.  As the Company  continues to
license its patents to certain of its competitors, competition will increase. As
a result of the above factors,  the Company expects to face  substantially  more
competition in the future than it has to date. Increased  competition could have
a material  adverse effect on the Company's  business,  financial  condition and
results  of  operations.  The  Company  believes  that its  ability  to  compete
successfully  depends on a number of factors,  which  include price and quality,
product performance and availability, success in developing new applications for
system flash technology, adequate foundry capacity, efficiency of

                                    Page 19



production,  and timing of new product  announcements  or  introductions  by the
Company,  the number and nature of the Company's  competitors in a given market,
successful  protection of  intellectual  property  rights and general market and
economic conditions.  There can be no assurance that the Company will be able to
compete  successfully against current and future competitors or that competitive
pressures  faced  by the  Company  will  not  materially  adversely  affect  its
business, financial condition or results of operations.

         Declining  Average  Sales  Prices.  The  Company has  experienced,  and
expects to  continue  to  experience,  declining  average  sales  prices for its
products.  For  example in the second  quarter of 1998  average  selling  prices
declined 18% compared to the second quarter of 1997. During this same period the
average  selling  price per  megabyte of capacity  declined  50%. The flash data
storage  markets in which the  Company  competes  are  characterized  by intense
competition.   Therefore,  the  Company  expects  to  incur  increasing  pricing
pressures  from its customers in future  periods,  which will likely result in a
further  decline in average sales prices for the Company's  products.  To offset
declining  average sales prices,  the Company  believes that it must continue to
achieve  manufacturing  cost  reductions  as well as develop new  products  that
incorporate  advanced  features and can be sold at higher average gross margins.
If, however,  the Company is unable to achieve such cost reductions,  it may not
be able to remain price competitive,  resulting in lost sales, and the Company's
gross margins could decline,  each of which could have a material adverse effect
on the Company's business, financial condition and results of operations.

         During the second  quarter of 1998,  the  semiconductor  industry  as a
whole experienced significant production over capacity, and a further decline in
DRAM  pricing.  This  "buyers  market"  has created an  environment  of somewhat
irrational pricing even in flash memories. The Company believes that the current
semiconductor  down  cycle  may  continue  for the  next few  quarters,  putting
continuing pressure on average selling prices and product gross margins.

          Risks Associated with International Operations. Sales of the Company's
products  have been  denominated  to date  primarily in United  States  dollars.
Increases in the value of the United States  dollar could  increase the price of
the  Company's  products  so that  they  become  relatively  more  expensive  to
customers in the local currency of a particular country,  leading to a reduction
in sales and profitability in that country. Given the recent economic conditions
in Asia and the weakness of many Asian currencies  relative to the United States
dollar,  the Company's products are relatively more expensive in Asia, which has
resulted and may continue to result in a decrease in the Company's sales in that
region.  In the second  quarter of 1998,  sales to the Japan  declined to 30% of
total sales,  primarily as a result of the Japanese  economic  crisis and market
recession.  If the current market conditions in Japan do not improve, or further
decline, results of operations may be adversely affected.

         All of the Company's  wafers are, and for the  foreseeable  future will
be, produced by foundries located outside the United States. Because the Company
currently purchases a significant portion of its flash wafers in Japanese Yen at
set prices,  and bills  certain  customers  in  Japanese  Yen,  fluctuations  in
currencies could materially  adversely affect the Company's business,  financial
condition  and  results  of  operations.  In  addition,  gains and losses on the
conversion to United States dollars of accounts receivable, accounts payable and
other monetary assets and liabilities arising from international  operations may
contribute to  fluctuations in the Company's  results of operations.  Due to its
reliance on export  sales and its  dependence  on  foundries  outside the United
States,   the   Company  is  subject  to  the  risks  of   conducting   business
internationally,   including   foreign   government   regulation   and   general
geopolitical  risks  such  as  political  and  economic  instability,  potential
hostilities and changes in diplomatic and trade relationships. Manufacturing and
sales of the  Company's  products may also be materially  adversely  affected by
factors  such  as   unexpected   changes  in,  or  imposition   of,   regulatory
requirements,  tariffs,  import and export  restrictions  and other barriers and
restrictions,  longer payment cycles,  greater difficulty in accounts receivable
collection,  potentially adverse tax consequences, the burdens of complying with
a variety of foreign laws and other  factors  beyond the Company's  control.  In
addition,  the laws of certain foreign countries in which the Company's products
are or may be developed,  manufactured or sold,  including  various countries in
Asia,  may not protect the Company's  intellectual  property  rights to the same
extent as do the laws of the United States and thus make piracy of the Company's
products a more likely possibility.

                                    Page 20



There can be no assurance  that these  factors will not have a material  adverse
effect on the Company's business, financial condition or results of operations.

         Customer Concentration. A limited number of customers have historically
accounted  for a substantial  portion of the Company's  revenues and the Company
expects this trend to continue.  Sales to the Company's  customers are generally
made pursuant to standard purchase orders rather than long-term  contracts.  The
Company has also experienced significant changes in the composition of its major
customer  base from year to year and  expects  this  variability  to continue as
certain customers increase or decrease their purchases of the Company's products
as a result of fluctuations in market demand for such customers' products. Under
a joint cooperation  agreement signed in January 1993, Seagate has the option to
market the Company's products  beginning in 1999 and, if exercised,  the Company
will be required to coordinate sales with Seagate so that up to one-third of the
Company's  worldwide net revenues could be generated from sales of the Company's
flash products through  Seagate.  SanDisk may terminate this agreement by giving
one year written notice of termination beginning in January 1999.

         Dependence  on Third Party  Foundries.  All of the  Company's  products
require silicon wafers, which are currently supplied by United  Microelectronics
Corporation  ("UMC")  in Taiwan  and  Matsushita  in Japan.  The  Company  has a
development  agreement with NEC in Japan,  pursuant to which the Company expects
to receive initial wafer shipments once the products under development  complete
internal  qualification.  In the third  quarter  of 1997,  the  Company  made an
investment  in USIC,  a  semiconductor  manufacturing  venture  headed by UMC in
Taiwan.  The Company has arranged to receive  foundry wafers from a separate UMC
fabrication  facility  during the  qualification  of the USIC plant.  During the
second  quarter  of  1998,  the  Company  received  first  wafers  from the USIC
facility.  Under the current development  schedule,  the Company should complete
the qualification and start production at USIC in the third quarter of 1998. The
Company is  dependent  on its  foundries to allocate to the Company a portion of
their foundry capacity sufficient to meet the Company's needs, to produce wafers
of acceptable  quality and with acceptable  manufacturing  yields and to deliver
those  wafers to the Company on a timely  basis.  On  occasion,  the Company has
experienced  difficulties  in each of  these  areas.  The loss or  reduction  of
capacity  from any of its  foundry  suppliers  or the  inability  to  qualify or
receive the anticipated level of capacity from any of its manufacturing partners
could  have a  material  adverse  effect on the  Company's  business,  financial
condition  and results of  operations.  There can be no  assurance  that the NEC
fabrication  facility  will  commence  shipments  on  schedule  or that the USIC
facility will begin  production as  scheduled,  or that the processes  needed to
fabricate wafers for the Company will be qualified at either facility. Moreover,
there can be no assurance  that any of the Company's  suppliers  will be able to
maintain  acceptable  yields or  deliver  sufficient  quantities  of wafers on a
timely basis.

         Under each of the  Company's  wafer supply  agreements,  the Company is
obligated to provide a monthly rolling forecast of anticipated  purchase orders.
Except in limited circumstances and subject to acceptance by the foundries,  the
estimates  for the first  three  months of each  forecast  constitute  a binding
commitment  and the  estimates  for the  remaining  months may not  increase  or
decrease by more than a certain  percentage from the previous month's  forecast.
These   restrictions  limit  the  Company's  ability  to  react  to  significant
fluctuations in demand for its products.  As a result,  the Company has not been
able to match its purchases of wafers to specific  customer orders and therefore
the  Company  has from  time to time  taken  write  downs for  potential  excess
inventory  purchased prior to the receipt of customer orders and may be required
to do so in the future.  These adjustments decrease gross margins in the quarter
reported and have resulted,  and could in the future result in  fluctuations  in
gross  margins  on a  quarter  to  quarter  basis.  To the  extent  the  Company
inaccurately  forecasts  the  number of wafers  required,  it may have  either a
shortage  or an excess  supply of wafers,  either of which could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.   Additionally,  if  the  Company  is  unable  to  obtain  scheduled
quantities  of wafers from any foundry with  acceptable  yields,  the  Company's
business,  financial  condition  and results of  operations  could be negatively
impacted. See "Fluctuations in Operating Results."


                                    Page 21



         Dependence on Sole Source Suppliers and Third Party Subcontractors. The
Company purchases several critical components from single or sole source vendors
for  which  alternative  sources  are  not  currently   available.   Even  where
alternative  suppliers  are  available,  a  significant  amount of time would be
required to qualify an additional vendor in the case of certain of the Company's
components.  The Company does not maintain  long-term supply agreements with any
of these vendors.  The inability to develop alternative sources for these single
or sole source components or to obtain sufficient quantities of these components
could result in delays or reductions in product  shipments which could adversely
affect the Company's  business,  financial  condition and results of operations.
For example,  the Company  relies on  Motorola,  Inc.  ("Motorola")  as the sole
source of certain designs of microcontrollers,  which are critical components in
the Company's  products.  The sole source risk associated with  microcontrollers
from  Motorola  is  heightened   during   transitions  from  one  generation  of
microcontrollers  to the next,  given the limited safety stock available  during
these  transitions.  In the  event  Motorola  were to  discontinue  shipment  of
microcontrollers  for any reason,  the time to design and qualify an alternative
source would be approximately  nine to twelve months.  The Company's reliance on
Motorola as its sole source of certain  microcontrollers  exposes the Company to
interruptions  of  supply  that  could  have a  material  adverse  effect on the
Company's business, financial condition and results of operations.

         The Company  uses  third-party  subcontractors  to assemble  the memory
components for its products and from time to time uses other  subcontractors  to
perform certain other assembly and test functions.  The Company has no long term
agreements  with these  subcontractors.  As a result of this  reliance  on third
party  subcontractors  for  assembly of a portion of its  products,  the Company
cannot directly  control product delivery  schedules,  which can lead to product
shortages or quality assurance problems that could increase  manufacturing costs
of the Company's products. Any problems associated with the delivery, quality or
cost of the  Company's  products  could  have a material  adverse  effect on the
Company's business, financial condition and results of operations.

         Risks  Associated  with  Transitioning  to New  Processes and Products.
Successive  generations  of the  Company's  products  incorporate  semiconductor
devices  with greater  memory  capacity  per chip.  In addition,  the Company is
continually  involved  in  joint  development  with  its  foundries  to  produce
semiconductor devices based upon smaller geometry manufacturing processes.  Both
the development of higher capacity  semiconductor devices and the implementation
of smaller geometry  manufacturing  processes are important  determinants of the
Company's  ability to decrease  the cost per  megabyte of its flash data storage
products.  The utilization of semiconductor devices with greater memory capacity
and the design and implementation of new semiconductor  manufacturing  processes
can  entail a  number  of  problems,  including  lower  yields  associated  with
semiconductor device production, problems associated with design and manufacture
of products to incorporate such devices,  and production delays.  Because of the
complexity of its products, the Company has periodically experienced significant
delays in the development and volume  production ramp up of its products.  There
can be no  assurance  that  similar  delays  will not occur in the  future.  Any
problems  experienced  by the  Company in its current or future  transitions  to
higher capacity memory devices or to new semiconductor  manufacturing  processes
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

         The Company has  developed  new products  based on D2 (Double  Density)
flash technology,  a new flash  architecture  designed to store two bits in each
flash memory cell. The Company began low-volume shipments of its 64Mbit D2 flash
products in the third quarter of 1997. The Company  introduced its new 80Mbit D2
flash chip in November 1997 and expects to begin customer  shipments of products
utilizing this chip in the second half of 1998. The Company  experienced  delays
in the  production  ramp up of the  64Mbit D2  technology  and has  subsequently
shifted its resources to the qualification and production  startup of the second
generation 80Mbit D2 design.  Consequently,  product revenues from the 64Mbit D2
were not  material in 1997,  and the product was made  obsolete by the 80Mbit D2
design.  The Company  believes  that D2 flash will be important to the Company's
ability  to  increase  the  capacity  and  decrease  the cost of  certain of its
products,  maintain its  competitive  advantage,  broaden its target markets and
attract strategic  partners.  High density flash memory,  such as D2 flash, is a
complex  technology  requiring tight  manufacturing  controls and effective test
screens. The shift to volume production for new flash products is particularly

                                    Page 22



prone to  problems  which  can  impact  both  reliability  and  yields,  thereby
increasing manufacturing costs. There can be no assurance that reliable and cost
effective D2 flash products can be manufactured  in commercial  volumes and with
yields  sufficient  to result in a lower cost per megabyte.  Furthermore,  flash
data storage  products  designed  with 80Mbit D2 flash are expected to initially
exhibit  approximately  one-quarter  of the write  performance  of the Company's
existing products when writing data into memory, potentially excluding their use
in certain applications, such as digital cameras, thereby limiting their revenue
generating potential.

         Manufacturing  Yields.  The fabrication of the Company's  products is a
complex  and precise  process  requiring  wafers  that are  produced in a highly
controlled and clean environment.  Semiconductor companies supplying the Company
with wafers  periodically have experienced  problems achieving  acceptable wafer
manufacturing yields.  Semiconductor manufacturing yields are a function both of
design technology,  which is developed by the Company, and manufacturing process
technology,  which is typically  proprietary to the foundry.  Because low yields
may  result  from  errors in  either  design or  manufacturing  failures,  yield
problems may not be  effectively  determined or improved until an actual product
exists that can be analyzed and tested to  recognize  process  sensitivities  in
relation to the design rules that were used. As a result, yield problems may not
be identified until the wafers are well into the production  process.  This risk
is  increased  due to the  fact  that  the  Company  receives  its  wafers  from
independent  offshore  foundries,  increasing  the effort and time  required  to
identify,  communicate and resolve manufacturing yield problems. There can be no
assurance  that the  Company's  foundries  will  achieve or maintain  acceptable
manufacturing  yields in the  future.  The  inability  of the Company to achieve
planned  yields from its foundries  could have a material  adverse effect on the
Company's business, financial condition and results of operations.

         Patents,  Proprietary Rights and Related Litigation. The Company relies
on a  combination  of patents,  trademarks,  copyright  and trade  secret  laws,
confidentiality   procedures   and   licensing   arrangements   to  protect  its
intellectual  property rights. The Company has been notified in the past and the
Company and its  foundries may be notified in the future of claims that they may
be  infringing  patents or other  intellectual  property  rights  owned by third
parties.  In the past the Company  has been  involved  in  significant  disputes
regarding its  intellectual  property  rights and believes it may be involved in
similar disputes in the future. There can be no assurance that in the future any
patents held by the Company will not be invalidated, that patents will be issued
for any of the Company's  pending  applications  or that any claims allowed from
existing or pending patents will be of sufficient scope or strength or be issued
in the primary  countries  where the  Company's  products can be sold to provide
meaningful protection or any commercial advantage to the Company.  Additionally,
competitors of the Company may be able to design around the Company's patents.

         To preserve its intellectual  property rights,  the Company believes it
may be  necessary  to initiate  litigation  against  one or more third  parties,
including but not limited to those the Company has already  notified of possible
patent  infringement.  In addition,  one or more of these parties may bring suit
against the  Company.  In March 1998,  the Company  filed a complaint in federal
court against Lexar for infringement of a fundamental  flash disk patent.  Lexar
has disputed  the  Company's  claim of patent  infringement,  claimed  SanDisk's
patent is invalid or unenforceable and asserted various counterclaims  including
unfair  competition,  violation of the Lanham Act,  patent misuse,  interference
with prospective  economic  advantage,  trade defamation and fraud.  SanDisk has
denied each of Lexar's  counterclaims.  In July 1998, the federal district court
denied  Lexar's  request to have the case  dismissed  on the grounds the Company
failed to perform an adequate prefiling investigation. As a result, discovery in
the Lexar suit will commence in August 1998.  The Company  intends to vigorously
enforce its patents,  but there can be no assurance  that these  efforts will be
successful.

         In the event of an adverse result in any such  litigation,  the Company
could be required to pay substantial  damages,  cease the  manufacture,  use and
sale  of  infringing   products,   expend   significant   resources  to  develop
non-infringing  technology,  discontinue the use of certain  processes or obtain
licenses to the infringing technology. Any litigation, whether as a plaintiff or
as a defendant, would likely result in

                                    Page 23



significant  expense to the  Company  and divert  the  efforts of the  Company's
technical and management personnel, whether or not such litigation is ultimately
determined in favor of the Company.  In addition,  the results of any litigation
are inherently uncertain.

         In the event the Company desires to incorporate  third party technology
into its  products or is found to infringe  on others'  patents or  intellectual
property  rights,  the  Company  may be  required  to  license  such  patents or
intellectual  property rights.  The Company may also need to license some or all
of its patent  portfolio to be able to obtain  cross-licenses  to the patents of
others. The Company currently has patent cross-license  agreements with Hitachi,
Intel, Samsung,  Sharp, SST and Toshiba. From time to time, the Company has also
entered into discussions with other companies regarding potential  cross-license
agreements for the Company's  patents.  However,  there can be no assurance that
licenses  will be  offered  or that the terms of any  offered  licenses  will be
acceptable to the Company.  If the Company obtains  licenses from third parties,
it may be required to pay license  fees or make  royalty  payments,  which could
have a material  adverse effect on the Company's  gross margins.  The failure to
obtain a license  from a third party for  technology  used by the Company  could
cause  the  Company  to  incur  substantial   liabilities  and  to  suspend  the
manufacture  of  products or the use by the  Company's  foundries  of  processes
requiring the technology,  or to expend  substantial  resources  redesigning its
products to  eliminate  the  infringement.  There can be no  assurance  that the
Company would be successful  in  redesigning  its products or that such licenses
would be available under reasonable terms. Furthermore,  any such development or
license  negotiations could require  substantial  expenditures of time and other
resources by the Company.

         As is common in the industry,  the Company agrees to indemnify  certain
of its suppliers and customers  for alleged  patent  infringement.  The scope of
such indemnity varies, but may, in some instances,  include  indemnification for
damages and expenses,  including  attorneys'  fees. The Company may from time to
time be engaged in litigation as a result of such  indemnification  obligations.
Third party claims for patent  infringement are excluded from coverage under the
Company's  insurance  policies.  There  can  be no  assurance  that  any  future
obligation to indemnify the  Company's  customers or suppliers,  will not have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.

         Management  of Growth.  The Company has  recently  experienced  and may
continue to experience  rapid growth,  which has placed,  and could  continue to
place,  a  significant  strain  on the  Company's  limited  personnel  and other
resources. To manage such growth effectively,  the Company will need to continue
to implement and improve its operational,  financial and management  information
systems and to hire,  train,  motivate and manage its employees.  In particular,
the Company has on occasion  experienced  difficulty in hiring the  engineering,
sales and marketing  personnel  necessary to support the growth of the Company's
business.  Competition  for such  personnel  is  intense,  and  there  can be no
assurance  that the Company will be successful in attracting  and retaining such
personnel  or that the Company  will be able to manage such growth  effectively.
The Company's ability to manage its growth will require a significant investment
in and  expansion of its existing  internal  information  management  systems to
support  increased  manufacturing,   accounting  and  other  management  related
functions.  The Company is in the process of  replacing  its  existing  in-house
information  system. The implementation of the new system will impact almost all
phases of the Company's operations (i.e., planning,  manufacturing,  finance and
accounting).  The new system is currently scheduled to become operational in the
fourth  quarter of 1998.  There can be no  assurance  that the Company  will not
experience  problems,  delays or unanticipated  additional costs in implementing
the new management  information system or in the use of its existing system that
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations, particularly in the period in which the new
system is brought online. The failure of the Company to successfully  manage any
of these issues would have a material adverse effect on the Company's  business,
financial condition and results of operations.

         Dependence  on  Key  Personnel.  The  Company's  success  depends  to a
significant  degree upon the  continued  contributions  of members of its senior
management  and  other  key  research  and  development,  sales,  marketing  and
operations personnel,  including,  in particular,  Dr. Eli Harari, the Company's
founder,  President and Chief Executive Officer. The loss of any of such persons
could have a material adverse effect

                                    Page 24



on the Company's business,  financial  condition and results of operations.  The
Company does not have an employment agreement or non-competition  agreement with
any of its employees.

         Volatility  of Stock  Price.  There has been a history  of  significant
volatility  in the market  prices of the  Company's  Common  Stock on the Nasdaq
National Market,  and it is likely that the market price of the Company's Common
Stock will continue to be subject to significant  fluctuations.  For example, in
1997,  the Company's  stock price  fluctuated  from a low of $8 7/8 to a high of
$40. The Company believes that future announcements  concerning the Company, its
competitors or its principal customers, including technological innovations, new
product  introductions,  governmental  regulations,  litigation  or  changes  in
earnings  estimated by analysts,  may cause the market price of the Common Stock
to fluctuate  substantially in the future.  Sales of substantial  amounts of the
Company's  outstanding  Common  Stock  in the  public  market  could  materially
adversely affect the market price of the Common Stock.  Further, in recent years
the stock market has experienced extreme price and volume fluctuations that have
particularly  affected  the  market  prices  of equity  securities  of many high
technology  companies  and that  often  have  been  unrelated  to the  operating
performance of such companies.  These  fluctuations as well as general economic,
political and market  conditions  such as recessions or  international  currency
fluctuations,  may  materially  adversely  affect the market price of the Common
Stock.

         Year 2000 Compliance.  The Company is aware of problems associated with
computer systems as the year 2000 approaches.  Year 2000 problems are the result
of common  computer  programming  techniques  that result in systems that do not
function  properly when  manipulating  dates later than  December 31, 1999.  The
issue is complex and wide ranging. The problem may affect transaction processing
computer  applications  used  by  the  Company  for  accounting,   distribution,
manufacturing,  and planning.  The problem may also affect embedded systems such
as building security systems, machine controllers and production test equipment.
Year 2000 problems with these systems may affect the ability or efficiency  with
which the company can perform  many  significant  functions,  including  but not
limited to: order processing, material planning, product assembly, product test,
invoicing,  and  financial  reporting.  In addition,  the problem may affect the
computer  systems of the Company's  suppliers and  customers,  disrupting  their
operations.  Year 2000 problems with the Company's  business partners may impact
the Company's sources of supply and demand.

         The  costs  and time  schedule  for the  Company's  Year  2000  problem
abatement   program  are  based  on   management's   best   estimates   for  the
implementation of its new management  information  system and year 2000 problems
uncovered to date. These estimates were derived utilizing numerous  assumptions,
including  that  the  most   significant  Year  2000  risks  have  already  been
identified,  that certain  resources  will continue to be available,  that third
party  plans will be  fulfilled,  and other  factors.  However,  there can be no
guarantee  that these  estimates will be achieved or that the  anticipated  time
schedule  will be met and actual  results  could  differ  materially  from those
anticipated.

         Specific  contingency  plans for systems that pose  significant risk to
on-going operations are being developed under the auspices of the Company's year
2000  Risk  Management  program.  If the  Company  is  unable  to  complete  the
replacement of its core  management  information  system in a timely manner,  an
alternative  plan has been developed.  This plan consists of applying  available
vendor  supplied  software  patches to the existing  system.  The costs and time
involved to  complete  this  alternative  are  expected  to be  minimal.  Should
previously  undetected  Year  2000  problems  be found in other  systems,  these
systems will either be upgraded, replaced, turned off, or operated in place with
manual  procedures  to  compensate  for their  deficiencies.  While the  Company
believes  that these  alternative  plans would be adequate to meet the Company's
needs without  materially  impacting its  operations,  there can be no assurance
that such  alternatives  would be successful  or that the  Company's  results of
operations  would  not  be  materially  adversely  affected  by the  delays  and
inefficiencies inherent in conducting operations in this manner.

         Failure  of  the  Company's   internal  computer  systems  or  of  such
third-party  equipment or software,  or of systems  maintained  by the Company's
suppliers, to operate properly with regard to the Year 2000 and thereafter could
require the  Company to incur  unanticipated  expenses  to remedy any  problems,
which

                                    Page 25



could  have a  material  adverse  effect on the  Company's  business,  operating
results and financial  condition.  There can be no assurance  that the Company's
insurance will cover losses from business  interruptions  arising from year 2000
problems of the Company or its suppliers.  Furthermore,  the purchasing patterns
of customers or potential  customers may be affected by Year 2000 issues.  which
could  have a  material  adverse  effect on the  Company's  business,  operating
results and financial condition.

         Effect of Anti-Takeover  Provisions.  The Company has taken a number of
actions that could have the effect of discouraging a takeover attempt that might
be  beneficial  to  stockholders  who wish to receive a premium for their shares
from a potential bidder.  The Company has adopted a Shareholder Rights Plan that
would cause substantial dilution to a person who attempts to acquire the Company
on terms not  approved by the  Company's  Board of  Directors.  The  Shareholder
Rights Plan may therefore  have the effect of delaying or preventing  any change
in  control  and  deterring  any  prospective  acquisition  of the  Company.  In
addition,  the  Company's  Certificate  of  Incorporation  grants  the  Board of
Directors the authority to issue up to 4,000,000  shares of Preferred  Stock and
to determine  the price,  rights,  preferences  and  privileges  of those shares
without any further vote or action by the Company's stockholders.  The rights of
the holders of Common  Stock will be subject to, and may be  adversely  affected
by, the  rights of the  holders  of any  shares of  Preferred  Stock that may be
issued in the future. While the Company has no present intention to issue shares
of Preferred  Stock,  such issuance,  while providing  desirable  flexibility in
connection with possible  acquisitions and other corporate purposes,  could have
the effect of making it more  difficult or less  attractive for a third party to
acquire  a  majority  of the  outstanding  voting  stock  of the  Company.  Such
Preferred Stock may also have other rights,  including economic rights senior to
the Common Stock,  and, as a result,  the issuance thereof could have a material
adverse effect on the market value of the Common Stock. Furthermore, the Company
is subject  to the  anti-takeover  provisions  of  Section  203 of the  Delaware
General  Corporation  Law  ("Section  203"),  which  prohibits  the Company from
engaging in a "business  combination"  with an  "interested  stockholder"  for a
period of three  years  after the date of the  transaction  in which the  person
first becomes an "interested  stockholder,"  unless the business  combination is
approved in a prescribed  manner. The application of Section 203 also could have
the effect of delaying or preventing a change of control of the Company.
