              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 September 30, 1997, and the results of
   operations and cash flows for the three and nine month periods ended
   September 30, 1997 and 1996. Because all the disclosures required by
   generally accepted accounting principles are not included, these interim
   condensed consolidated financial statements should be read in conjunction
   with the audited financial statements and notes thereto in the Company's
   annual report on Form 10-K as of, and for the year ended December 31, 1996.
   The condensed consolidated balance sheet data as of December 31,
   1996 was derived from the audited financial statements.

   The results of operations for the three and nine month periods ended
   September 30, 1997 and the statement of cash flows for the nine months ended
   September 30, 1997 are not necessarily indicative of results of operations
   and cash flows for any future period.

2. The Company's fiscal year ends on the Sunday closest to December 31, and each
   fiscal quarter ends on the Sunday closest to March 31, June 30, and September
   30.  The third fiscal quarter of 1997 and 1996 ended on September 28, 1997
   and September 29, 1996, respectively.  Fiscal year 1996 ended on December 29,
   1996.  For ease of presentation, the accompanying financial statements have
   been shown as ending on the last day of the calendar month.

3. The components of inventory consist of the following:

4. In February 1997, the Financial Accounting Standards Board issued Statement
   No. 128, Earnings per Share ("SFAS 128"), which is required to be adopted on
   December 31, 1997. At that time, the Company will be required to change the
   method currently used to compute earnings per share and to restate all prior
   periods. Under the new requirements for calculating primary earnings per
   share, the dilutive effect of stock options will be excluded. The impact is
   expected to result in an increase of $0.03 in net income per share for the
   three month periods ended September 30, 1997 and 1996 and an increase of
   $0.05 for the nine month periods ended September 30, 1997 and 1996. The
   calculation of diluted earnings per share under SFAS is not materially
   different from net income per share for the periods presented.


5. In October 1995, Samsung Electronics Company Ltd. filed a complaint against
   the Company in the Northern District of California accusing the Company of
   infringing two Samsung patents, seeking declaratory relief with respect to
   five Company patents and alleging unspecified damages for certain other
   related claims.   On January 11, 1996, the Company filed a complaint against
   Samsung with the United States International Trade Commission alleging that
   Samsung and its U.S. sales arm, were importing and selling products that
   infringe two of the Company's patents.  On February 26, 

                                       6
<PAGE>
 
   1997, the Administrative Law Judge assigned to the case issued an Initial
   Determination finding both SanDisk patents valid and infringed and further
   finding a violation of Section 337 of the Trade Act. On June 2, 1997, the
   Commission issued a limited exclusion order prohibiting the unlicensed entry
   of infringing flash memory circuits, and carriers and circuit boards
   containing such circuits, that are manufactured by or on behalf of Samsung.
   On August 14, 1997, in connection with the settlement of all disputes between
   them, the Company and Samsung announced the signing of a patent cross license
   agreement for flash memory related patents. Under the agreement, the Company
   and Samsung have licensed each others patents covering the design and
   manufacture of flash memory products.

   The Company also entered into other cross-license agreements during the nine
   months ended September 30, 1997. Under these agreements, the Company received
   payments which were recognized as license and royalty revenues and portions
   of which are deferred revenue. Recognition of deferred revenue is expected to
   occur in future periods as the Company meets certain obligations as provided
   in the various agreements.

   Litigation frequently involves substantial expenditures and can require
   significant management attention, even if the Company ultimately prevails. In
   addition, the results of any litigation matters are inherently uncertain.
   Accordingly, there can be no assurance that any future litigation will not
   have a material adverse effect on the Company's business, financial condition
   and results of operations.

6. On April 21, 1997, the Company adopted a shareholder rights plan (the Rights
   Agreement).  Under the Rights Agreement, rights were distributed as a
   dividend at the rate of one right for each share of common stock of the
   Company held by stockholders of record as of the close of business on April
   28, 1997.  The rights will expire on April 28, 2007 unless redeemed or
   exchanged.  Under the Rights Agreement, each right will initially entitle the
   registered holder to buy one one-hundredth of a share of Series A Junior
   Participating Preferred Stock for $65.00.  The rights will become exercisable
   only if a person or group (other than Seagate Corporation, which is permitted
   to maintain its 25% stake in the Company) acquires beneficial ownership of 15
   percent or more of the Company's common stock or commences a tender or
   exchange offer upon consummation of which such person or group would
   beneficially own 15 percent or more of the Company's common stock.

7. The Company recorded a provision for income taxes at a 15% effective tax rate
   for the first nine months of 1997 compared to a 6.5% effective tax rate for
   the same period of 1996.  The effective tax rate for the first nine months of
   1997 is 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. In the third quarter of 1997, the Company invested $40.2 million in United
   Silicon, Inc., ("USIC") a semiconductor manufacturing joint venture headed
   by United Microelectronics Corporation in Taiwan. The transaction gives the
   Company an equity stake of approximately 10% in the joint venture (which
   will be accounted for on the cost basis) and guarantees access to
   approximately 12.5% of the wafer output from the facility.

9. The Company has a credit agreement (the Agreement) with a bank, which was
   renewed in July 1997. Under the provisions of the Agreement, which expires in
   July 1998, the Company may borrow up to $10,000,000 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 of up to the full
   amount of the credit line. At September 30, 1997, $7,200,000 in letters of
   credit were outstanding. In addition, under the Agreement, the Company also
   has a $15,000,000 foreign exchange contract line under which the Company may
   enter into foreign exchange contracts. No amounts were outstanding under
   the revolving line of credit portion of the Agreement and the foreign
   exchange contract portion of the line at September 30, 1997. 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. At September 30, 1997 the Company was not in
   compliance with the quick ratio coventant due to the increase in deferred
   revenue. Following the end of the quarter, the financial covenants were
   retroactively amended by the bank and the Company is in compliance with all
   financial covenants as amended.

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, 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, 1996 and the Company's Form 10-Q for the quarter ended June
30, 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 CompactFlash for use in digital camera applications, has
increased substantially. This increase in sales to the consumer market has
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 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 shorten its manufacturing cycle time. 

  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 revenue, fluctuations in product costs, availability of foundry 
capacity, variations in manufacturing cycle times, fluctuation in manufacturing 
yields and manufacturing utilization, increased research and development 
expenses, exchange rate fluctuations and changes in the Company's effective tax 
rate. 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" 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 five major 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
revenue than with changes in product revenues.

  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 does not expect to recognize
revenues from these sales until the products are sold to the end customers. 
 
  Historically, a majority of the Company's sales have been to a limited number 
of customers. Sales to the Company's top ten customers accounted for 
approximately 64% and 71%, respectively, of the Company's total revenues for the
nine months ended September 30, 1997 and the year ended December 31, 1996. The
Company expects that sales of its products to a limited number of customers will
continue to account for a substantial portion of its total 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. For example,
during the fourth quarter of 1996, the volume of large OEM orders decreased due
to the timing of customers' product introductions. 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. The
majority of the Company's sales in 1996 were of FlashDisk cards. However, during
the first nine months of 1997, the largest portion of the Company's sales were
of CompactFlash products. 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 
taken write downs for potential excess inventory purchased prior to the receipt 
of customer orders. 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 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 significant 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.
 
  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 NEC
Corporation ("NEC") and United Silicon, Inc. ("USIC"). To remain competitive,
the Company is focusing on a number of programs to lower its manufacturing
costs. These include transitioning from single to double density flash
designs, from 0.5 to 0.4 micron manufacturing processes, and from six inch to
eight inch wafers. These transitions are expected to occur over the next
several quarters. As a result of these factors, the Company expects that
product gross margins may decline in the near term from the level experienced
in the quarter ended September 30, 1997, and product gross margins are
expected to be subject to fluctuation for the foreseeable future. Moreover,
there can be no assurance that such devices or processes will be successfully
developed by the 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."

RESULTS OF OPERATIONS

     Product Revenues.  SanDisk's product revenues were $30.2 million in the
     ----------------                                                       
third quarter of 1997, up $5.4 million or 22% from the same period of 1996.
Product revenues for the first nine months of 1997 were $72.3 million, up $4.7
million or 7% from the same period in 1996. During the three and nine month
periods ended September 30, 1997, units shipped increased 188% and 149%,
respectively, from the same periods of 1996. The largest increase came from
sales of CompactFlash products primarily for use in digital cameras and other
consumer electronics applications. In the second and third quarters of 1997,
sales of CompactFlash products exceeded sales of PCMCIA flash cards. In the
first nine months of 1997, CompactFlash products represented approximately 74%
of all units shipped and 47% of product revenues. This shift in product mix from
PCMCIA flash cards to CompactFlash cards, which have lower capacities,
contributed to a decline in average selling prices of 57% in the first nine
months of 1997 compared to the same period last year. The Company anticipates
that lower capacity products will continue to represent a significant portion of
its sales as consumer applications such as digital cameras become more popular.
Sales of these lower capacity products generally have lower average selling
prices and gross margins than higher capacity 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.

     Orders for the Company's products increased during the third quarter of
1997 as consumer electronics OEM customers increased their inventory of
CompactFlash products in preparation for the upcoming holiday season and their
new product introductions. Although the Company has limited visibility as to
customer orders, the Company expects product revenues in the fourth quarter of
1997 to be flat, or possibly up slightly relative to the third quarter of 1997.
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. The outlook for
product revenues for the first quarter of 1998 is also uncertain due to the
unpredictable demand in the new and emerging markets for the Company's
products and the anticipated seasonality of the consumer electronics markets.
See "Risk Factors-Fluctuations in Operating Results" 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 and gross margins to decline.
 
     Export sales represented 60% of product revenues in the third quarter and
53% of product revenues in the first nine months of 1997, compared with 65% and
56% 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 67% of product revenue in the third
quarter of 1997 compared to 75% for the third quarter of 1996.   For the first
nine months of 1997 and 1996, the Company's top ten customers represented 64% of
product revenue. 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 five cross license agreements, of which agreements
with 

                                       8
<PAGE>
 
Hitachi, Toshiba and Samsung were entered into in the third quarter of 1997.
SanDisk also has cross-license agreements with Intel and Sharp. License and
royalty revenue from patent cross license agreements was $5.9 million in the
third quarter of 1997, up $4.7 million from $1.3 million in the same period of
1996. Revenues from patent licenses and royalties increased to 16% of total
revenues in the third quarter of 1997 from 5% in the same period of the
previous year. License and royalty revenue from patent cross license
agreements was $12.6 million for the first nine months of 1997, up $8.8
million from $3.8 million in the comparable period of 1996. Revenues from
licenses and royalties represented 15% of total revenues in the first nine
months of 1997 compared to 5% in the same period of 1996.
 
 
     Gross Profits.  In the third quarter of 1997, gross profits increased to
     -------------                                                           
$16.0 million or 44% of total revenues from $10.3 million or 39% of total
revenues for the same period in the previous year. Gross profits for the first
nine months of 1997 increased to $35.5 million or 42% of total revenues from
$27.8 million or 39% of total revenues for the same period in 1996. Product
gross margins were 33% in the third quarter of 1997 compared to 36% for the same
period of 1996. The growth in overall gross profits for the first nine months of
1997 resulted from an increase in license and royalty revenue, which was
partially offset by a decline in gross profit from product sales. Product gross
margins declined as a percentage of product revenue to 32% for the first nine
months of 1997 compared to 36% for the same period in 1996. The decline was
primarily due to the shift in product mix to lower capacity CompactFlash
products that have lower average selling prices and gross margins. This decline
in gross margins was partially offset by a reduction in manufacturing cost per
unit resulting from the Company's shift to more in-house assembly and test. The
Company anticipates that lower capacity products will continue to represent a
significant portion of its sales as consumer applications such as digital
cameras become more popular. The Company expects product gross margins may
decrease slightly in the fourth quarter of 1997 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 $0.8 million or 30% in the third quarter of 1997 and $2.4
million or 32% for the first nine months of 1997 compared to the same periods
in 1996. Research and development expenses represented 10% of total revenues
for the third quarter of 1997 and 11% of total revenues for the first nine
months of 1997 compared to 10% for the same periods in 1996. The increase in
research and development expenses for both the third quarter and first nine
months of 1997 was primarily due to an increase in salaries and payroll
related expenses associated with additional personnel. Increased depreciation
due to capital equipment additions and higher project related expenses also
contributed to the growth in research and development expenses. 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.

     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 $1.0
million or 48% in the third quarter of 1997, and $2.3 million or 35% for the
first nine months of 1997, compared to the same periods in 1996. Sales and
marketing expenses represented 9% of total revenues in the third quarter of
1997, and 10% of total revenues for the first nine months of 1997 compared to 8%
in the third quarter of 1996 and 9% for the first nine

                                       9
<PAGE>
 
months of 1996. The increase in sales and marketing expenses for the three and
nine month periods ended September 30, 1997 was primarily due to an increase in
salaries and payroll related expenses associated with additional personnel.
Higher marketing, travel and selling expenses also contributed to this
increase. The Company expects sales and marketing expenses to increase in
absolute dollars as sales of its products grow and it attempts to develop the
retail channel for its products.

     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 decreased $0.3 million or 11% in the third quarter of
1997 and $0.6 million or 12% in the first nine months of 1997 compared to the
same periods of 1996.   General and administrative expenses represented 6% of
total revenues in the three and nine month periods ended September 30, 1997
compared to 9% for the third quarter and 8% for the first nine months of 1996.
The decrease was primarily due to a reduction in legal fees. The first nine
months of 1996 included significant legal fees related to the Samsung
litigation. The decrease in legal fees was partially offset by increased
salaries and payroll related expenses associated with additional personnel,
increased allowance for doubtful accounts and higher consulting expenses
related to the planned implementation of the Company's new management
information system. The Company expects general and administrative expenses to
increase in absolute dollars as the general and administrative functions grow to
support the overall growth of the Company. General and administrative expenses
could also increase substantially in the future if the Company pursues
litigation to defend its patent portfolio. See "Risk Factors-Patents Proprietary
Rights and Related Litigation."

     Interest and Other Income, Net.  Interest and other income, net, decreased
     ------------------------------                                            
$28,000 in the third quarter of 1997 compared to the same period of 1996.  This
decline was due to lower investment balances primarily due to the current
quarter investment in the USIC foundry joint venture.  For the nine months ended
September 30, 1997, interest and other income, net, increased $360,000 due to
higher interest rates on short-term investments.

          Provision for Income Taxes. The Company recorded a provision for
          --------------------------                                      
income taxes at a 15% effective tax rate for the first nine months of 1997
compared to a 6.5% effective tax rate for the same period of 1996.  The
effective tax rate for the first nine months of 1997 is 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 1997 effective tax rate
is substantially higher than its 1996 rate due to the utilization of all federal
net operating loss carryforwards in 1996.

  Due to increased license and royalty revenues and growth in the Company's net 
income in 1997, the Company anticipates that it will utilize the remainder of 
its tax credit carryforwards in the current fiscal year. The Company's 
effective tax rate is expected to increase significantly in 1998 and is 
expected to approach the statutory tax rate. 
 
LIQUIDITY AND CAPITAL RESOURCES

     As of September 30, 1997, the Company had working capital of $48.0 million,
which included $18.3 million in cash and cash equivalents and $42.0 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 1998. As of September 30,
1997, the Company had $7.2 million committed under the line of credit facility
for standby letters of credit. 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. At September 30, 1997,
the Company was not in compliance with the quick ratio covenant due to the
increase in deferred revenue. Following the end of the quarter, the financial
covenant was retroactively amended by the bank and the Company is currently in
compliance with all financial covenants as amended.
 
     Operating activities provided $30.5 million of cash during the first nine
months of 1997. In addition to net income, sources of cash included increased
deferred revenue of $26.3 million, primarily from the receipt of funds under
patent license and royalty agreements, and an increase in current liabilities
of approximately $4.0 million. These were partially offset by increases in
accounts receivable, inventory, and prepaid expenses and other assets totaling
$15.3 million. Investing activities used $33.1 million of cash in the first
nine months of 1997. Investing activities for the third quarter of 1997
included a $40.2 investment in the USIC foundry joint venture and $5.8 million
of capital equipment purchases, which were partially offset by net proceeds
from investment activity of $13.0 million. The Company paid the entire balance
due on its investment in the USIC foundry joint venture during the third
quarter of 1997, in advance of its original due date of April 1, 1998.

     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 to support its business in the future. Management
believes the existing cash and cash equivalents, short term investments and
available line of credit will be sufficient to meet the Company's currently
anticipated working capital and capital expenditure requirements for 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 September 30, 1997, there were no forward contracts
outstanding.  Future exchange rate fluctuations could have a material adverse
effect on the Company's business, financial condition and results of operations.

                                      10

                                 RISK FACTORS
 
  Fluctuations in Operating Results. SanDisk's operating results have been in
the past and are expected to be in the future, subject to quarterly and annual
fluctuations due to a variety of factors. For example, the Company's revenues
increased each quarter for the first three quarters of 1996 and then decreased
in both the last quarter of 1996 and the first quarter of 1997 before
increasing in the second and third quarters of 1997. 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 the unpredictable demand for the Company's products and
anticipated seasonality as sales of products for consumer electronics
applications become a greater proportion of the Company's product revenues.
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. If the Company underestimates the number of silicon wafers required
in a particular quarter and is unable to fulfill customer orders promptly
after receipt of an order, the Company will risk losing potential sales and
customers. Since 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 remains high 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
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 the Company's
effective tax rate. 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 recent 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,
increased marketing efforts and additional 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.
 
                                       11
<PAGE>
 
  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. Over the last three quarters, the Company
experienced a shift in product mix to low capacity (2MB and 4MB) CompactFlash
cards that generally have lower average selling prices and lower gross margins
than high capacity products. This shift in product mix, coupled with lower
pricing due to competition, caused average selling prices to decline. The
Company anticipates that lower capacity products will continue to represent a
significant portion of its sales as consumer applications such as digital
cameras become more popular.
 
  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 is likely to continue to 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. There can be no assurance that the Company will
develop successfully 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.
 
  Increasing Dependence on Consumer Products. During the first nine months of
1997, the portion of the Company's product revenues derived from sales of
products for consumer electronics applications, principally digital cameras,
increased significantly and over this period represented the largest portion
of product revenues and units shipped. 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 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. In addition, if
market acceptance of digital cameras is 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

                                      12 
<PAGE>
 
and retail chains, which typically maintain rights to return unsold inventory.
As a result, the Company does not expect to 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. During the course of 1997, the
Company's product mix has increasingly shifted towards CompactFlash products,
which are sold principally for consumer electronics applications. The Company
anticipates that this trend will continue. As a result, the Company expects
that its product sales will be increasingly 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. The Company believes product revenues during the
third quarter of 1997 included purchases by consumer electronics OEM customers
in anticipation of new product introductions and the fourth quarter holiday
season. 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. As a
result of these factors, sales for the first quarter of 1998 are uncertain and
it is possible that product revenues in that quarter could be below the levels
experienced in the third quarter and anticipated in the fourth quarter of
1997. The Company expects that its operating expenses may continue to increase
over this time period. Accordingly, a decrease in revenues in any quarter
would adversely impact the Company's results of operations in that period.
 
  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 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 assemblers
such as LEXAR Technology Inc. ("LEXAR"), M-Systems, Inc. ("M-Systems"), SIMPLE
Technology Inc. ("SIMPLE"), SMART Modular Technologies, Inc. ("SMART Modular")
and Viking Components, Inc. ("Viking") that combine controllers and flash memory
chips developed by others into flash data storage cards. Hitachi, LEXAR,
Mitsubishi and Micron have been certified by the CompactFlash Association
("CFA") to manufacture and sell their own brand of CompactFlash, and the Company
believes that other manufacturers will also seek to 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 Solid-State Floppy Disk Card and Sony
Corporation's recently introduced Memory Stick. 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 the
fourth quarter of 1996, Iomega Corporation ("Iomega") announced plans to
introduce n.hand, a miniaturized, mechanical, removable disk drive that may
compete directly with SanDisk's flash card 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
 
                                      13
<PAGE>
 
competition is expected to result in lower gross margins in the future, if the
Company's average selling prices decrease faster than its costs.
 
   The Company has entered into patent cross-license agreements with Hitachi,
Intel, Samsung, Sharp and Toshiba, pursuant to which each party may
manufacture and sell products that incorporate technology covered by each
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 production, timing of new product announcements or introductions
by the Company, its customers and its competitors, the ability of the
Company's competitors to incorporate their flash data storage systems into
their customers' products, 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. The
flash data storage markets in which the Company competes are characterized by
increasing competition. Therefore, the Company expects to incur increasing
pricing pressures from its customers in future periods, which could result in
declining 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, the Company's
gross margins could decline, and such decline could have a material adverse
effect on the Company's business, financial condition and 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. The Company's 10 largest customers accounted
for 71% and 55% of total revenues in 1996 and the first nine months of 1997,
respectively. 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.
 
  Dependence on Third Party Foundries. All of the Company's products require
silicon wafers, which are currently supplied by Matsushita in Japan and LG
Semicon in Korea. The Company has also entered into a wafer supply agreement
with NEC in Japan, pursuant to which the Company expects to receive initial
wafer shipments in 1998. In the third quarter of 1997, the Company made an
investment in USIC, a semiconductor manufacturing joint venture headed by UMC
in Taiwan, which has a fabrication facility currently under construction. 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 Matsushita or LG Semicon 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
 
                                      14
<PAGE>
 
no assurance that the NEC fabrication facility will commence shipments on
schedule or that the USIC facility will be completed or 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 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."
 
  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 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 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. With the significant increases in
unit shipments in the last few quarters, the Company has from time to time
experienced capacity constraints in the memory assembly area. 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. Most of the Company's wafers are currently manufactured using 0.5
micron process technology. The Company has started limited production of 0.4
micron flash wafers at Matsushita and expects to begin receiving 0.4 micron
wafers from LG Semicon in the first half of 1998. There
 
                                      15
<PAGE>
 
can be no assurance that the Company and its foundries will successfully
complete the transition from 0.5 to 0.4 micron process technology without
adversely impacting wafer yields or the effective cost per die, or that any of
these suppliers will be able to maintain acceptable yields or deliver
sufficient quantities of wafers on a timely basis. 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.
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.
 
  In addition, Matsushita and LG Semicon are shifting their production
capacity from six inch wafers to eight inch wafers. Consequently, the Company
is planning to shift to volume production of eight inch wafers and discontinue
six inch wafer production at both facilities in 1998. There can be no
assurance that the transitions from six inch to eight inch wafer production
will be completed smoothly and without adversely impacting wafer yields or the
effective cost per die, or that any of these suppliers will be able to
maintain acceptable yields or deliver sufficient quantities of wafers on a
timely basis.
 
  The Company has developed new products based on D2 flash technology, a new
flash system designed to store two bits in each flash memory cell. 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 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 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 limiting their use in
certain applications.
 
  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 in achieving acceptable wafer
manufacturing yields. Semiconductor manufacturing yields are a function both
of design technology, which is developed by the Company, and process
technology, which is typically proprietary to the foundry. Because low yields
may result from errors in either design or process technology 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
 
                                      16
<PAGE>
 
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 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 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 matter are inherently
uncertain. For example, in 1995, the Company informed Samsung that the Company
believed Samsung infringed certain of its patents. In response, Samsung filed
a complaint accusing the Company of infringing two of its patents. The Company
then filed a complaint against Samsung with the United States International
Trade Commission (the "ITC") alleging that Samsung and its U.S. sales arm were
importing and selling products that infringed two of the Company's patents.
After a hearing on this matter, the ITC issued an order that both SanDisk
patents were valid and that Samsung had infringed such patents, and prohibited
the import, sale, marketing, distribution or advertising of Samsung's
infringing flash memory circuits in the United States. In August 1997, the
Company and Samsung entered into a settlement agreement resolving all aspects
of this dispute, pursuant to which the parties agreed to cross-license certain
patents and Samsung agreed to make license and royalty payments to the
Company. While the Company believes it achieved a favorable result in this
matter, the expense and diversion of management attention in connection with
its resolution were substantial. In addition, the Company has notified several
large flash suppliers that the Company believes certain of their existing or
announced products infringe certain of the Company's patents.
 
  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 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. See "Business--Patents and Licenses."

  Risks Associated with International Operations. In 1996 and the first nine
months of 1997, export sales accounted for approximately 55% of the Company's
total revenues. 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 the majority of its flash wafers in
Japanese Yen at set prices, fluctuations in currencies could materially
adversely affect the Company's business, financial condition and 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. In
addition, since most of the Company's international sales are denominated in
U.S. dollars, the Company's products may be less competitive in countries with
currencies declining in value against the dollar. 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. 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.
 
  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 recently 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 recently purchased a new management information system to replace
its existing in-house information system, and the implementation of this new
system will impact almost all phases of the Company's operations (i.e.,
planning, manufacturing, finance and accounting). This system is currently
scheduled to become operational in the second half 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. In addition, the Company recently brought in-house certain assembly
operations that were previously performed by outside vendors. The Company has
limited experience in performing these functions and there can be no assurance
it will be able successfully integrate these operations into its manufacturing
process. In addition, if the Company experiences problems with these in-house
operations, it may be difficult to quickly substitute outside vendors. 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 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. See "Business--
Employees" and "Management."
 
  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
 
                                      18
<PAGE>
 
Company's Common Stock will continue to be subject to significant
fluctuations. For example, in 1997, the Company's stock price has fluctuated
from a low of $8 7/8 to a high of $39 5/8. 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. Many currently installed computer systems and software
products are coded to accept only two digit entries in the date code field.
Beginning in the year 2000, these date code fields will need to accept four
digit entries to distinguish 21st century dates from 20th century dates. As a
result, in less than three years, computer systems and/or software used by
many companies may need to be upgraded to comply with such "Year 2000"
requirements. Significant uncertainty exists concerning the potential effects
associated with such compliance. The Company is currently implementing a new
managment information system that is Year 2000 compliant. Any Year 2000
compliance problem of either the Company or its customers could result in 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

                                      19 
<PAGE>
 
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.

Dear Ms. Burgdorf and Mr. Gray:

        On behalf of Mr. Robert Tsao and UMC, I have been authorized to confirm 
my earlier verbal reassurance: Neither United Microelectronics Corporation nor 
United Silicon Inc. ("USIC") will assert or raise any breach of contract claim 
under our existing agreements as a result of any election by SanDisk not to 
invest further funds into USIC. 

        As mentioned, from our perspective, Mr. Robert Tsao's letter of May 28 
attempted to make this quite clear.

        "Accordingly, and conditioned upon SanDisk acquiring and holding the 
shares involved in its investment as described above, we promise that SanDisk 
will not be required to make any additional investment in USI beyond the amounts
committed under item 1 above: (i) in order to preserve its right of first 
refusal with respect to proportional capacity in that amount, or (ii) in order 
to retain a seat on the board of directors during the first term (i.e., during 
the first three years)."

        I also wish to confirm again that Mr. Tsao's letter of May 28 is an 
integral part of the UMC/SanDisk relationship; that letter was sent to SanDisk 
with the understanding that it formed a material part of your decision to enter 
the Foundry Venture Agreement.

        I hope this letter satisfactorily resolves the matters raised in our 
telephone call.

                                                Yours sincerely,

                                                /s/ Peter Courture
                                                Peter Courture
                                                General Counsel
