1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

        The accompanying condensed consolidated financial statements have been
prepared by Network Appliance, Inc. without audit and reflect all adjustments,
which are, in the opinion of management, necessary for a fair presentation of
our financial position and results of operations for the interim periods. The
statements have been prepared in accordance with the regulations of the
Securities and Exchange Commission (SEC). Accordingly, they do not include all
information and footnotes required by generally accepted accounting principles.
The results of operations for the three and nine-month periods ended January 28,
2000 are not necessarily indicative of the operating results to be expected for
the full fiscal year or future operating periods. The information included in
this report should be read in conjunction with the audited consolidated
financial statements and notes thereto for the fiscal year ended April 30, 1999
and the risk factors as set forth in our Annual Report on Form 10-K, including,
without limitation, risks relating to fluctuating operating results, customer
and market acceptance of new products, dependence on new products, rapid
technological change, litigation, dependence on growth in the network file
server market, expansion of international operations, product concentration,
changing product mix, competition, management of expanding operations,
dependence on high-quality components, dependence on proprietary technology,
intellectual property rights, dependence on key personnel, volatility of stock
price, shares eligible for future sale, effect of certain anti-takeover
provisions, dilution and the Year 2000 Issue. Any party interested in reviewing
these publicly available documents should contact the SEC or our Chief Financial
Officer.


2. SIGNIFICANT ACCOUNTING POLICIES

        Fiscal Periods - We operate on a 52-week or 53-week year ending on the
last Friday in April. Fiscal 2000 is a 52-week year. Fiscal 1999 was a 53-week
year. The quarter ended January 28, 2000 includes 13 weeks of operating
activity, compared to 13 weeks of activity for the corresponding period of the
prior fiscal year. The nine-months ended January 28, 2000 includes 39 weeks of
activity, compared to 40 weeks of activity for the corresponding period of the
prior fiscal year.

        Foreign Currency Translation - In the first quarter of fiscal 2000, we
determined that the functional currencies of certain of our foreign subsidiaries
had changed from the local currencies to the Euro. Accordingly, assets and
liabilities of such foreign subsidiaries are translated into the Euro at the
exchange rates in effect as of the balance sheet date, and results of operations
for each subsidiary are translated using average rates in effect for the period
presented. Translation adjustments have been included within shareholders'
equity as a cumulative other comprehensive loss. The effect of the change in
functional currencies did not have a material impact on our consolidated
financial position, results of operations or cash flows.

6. NEW ACCOUNTING PRONOUNCEMENTS

        In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which defines derivatives,
requires that all derivatives be carried at fair value, and provides for hedging
accounting when certain conditions are met. This statement is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. Although we have
not fully assessed the implications of this new statement, we do not believe
adoption of this statement will have a material impact on our consolidated
financial position, results of operations or cash flows.

7. COMMITMENTS

        In fiscal 1999, we executed agreements to acquire approximately 18 acres
of land in Sunnyvale, California and to develop 393,000 square feet of
buildings. We subsequently assigned our rights and obligations under all the
agreements for the Sunnyvale facilities to a third-party entity and entered into
three operating leases. The leases require monthly payments, which vary, based
on the London Interbank Offered Rate (LIBOR) plus a spread (7.5% at January 28,
2000). The aggregate annual minimum rent commitment under one lease, which began
in August 1999, is approximately $3.3 million. The lease payments under the
other two operating leases are expected to commence in June 2000 and will also
vary based on LIBOR plus a spread.

        The operating leases mentioned above require us to maintain specified
financial covenants with which we were in compliance as of January 28, 2000.

        We have commitments related to operating lease arrangements, under which
we have an option to purchase the properties for an aggregate of $190.0 million,
or arrange for the sale of the properties to a third party for at least the
option price with a contingent liability for any deficiency.

8.      SUBSEQUENT EVENTS

        On February 10, 2000, the Board of Directors approved a two-for-one
stock split of the Company's common stock to be distributed on or about March
22, 2000 to holders of record on March 10, 2000. Pro forma share and per-share
amounts have been presented within the Condensed Consolidated Statements of
Income to reflect the stock split.

        Net Sales -- Net sales increased by 100.1% to $151.3 million for the
three-months ended January 28, 2000, from $75.6 million for the three-months
ended January 29, 1999. Net sales increased by 91.0% to $379.3 million for the
nine-months ended January 28, 2000, from $198.6 million for the nine-months
ended January 29, 1999. Net sales growth was across all geographies, products
and markets. This increase in net sales for both the three and nine-months ended
January 28, 2000 was primarily attributable to a higher volume of units shipped,
as compared to the corresponding periods of the prior fiscal year. Factors
impacting unit growth include:

        -      growth in the network attached storage market and increased
               market acceptance of the appliance concept;

        -      acceleration in deployment of our products among Internet and
               enterprise related customers, particularly for E-business and
               database applications;

        -      strong demand for our F700 filer product family utilizing
               primarily fibre-channel connectivity;

        -      increased worldwide demand for our NetCache(TM) solutions;

        -      increased worldwide shipment of NetApp(R) Cluster Failover
               solutions, which require another filer to take over in the event
               of a hardware failure;

        -      increased demand for the SnapMirror(TM) software option, which
               requires multiple filers to provide remote mirroring of data for
               quick disaster recovery and backup at remote sites;

        -      expansion of our direct sales force; and

        -      sales to our two OEM partners.



                                       8
   10

        Net sales growth was also positively impacted by:

        -      a higher average selling price due to the introduction of new
               software features: SnapMirror, SnapRestore(TM) and Cluster
               Failover, supporting mission-critical applications;

        -      the increase in storage capacity;

        -      increased add-on software revenue from multi-protocol solutions;
               and

        -      higher software subscription and service revenues to support a
               growing installed base.

        Overall net sales growth was partially offset by declining unit sales of
our older product family and declining average selling price of the caching
product family due primarily to competitive pricing pressure.

        International net sales (including United States exports) grew by 50.0%
and 79.9% for the three and nine-month periods ended January 28, 2000, as
compared to the comparable period of the prior fiscal year. International net
sales were $46.9 million, or 31.0% of total net sales, and $109.6 million, or
28.9% of total net sales, for the three and nine-month periods ended January 28,
2000, respectively. The increase in international sales for the three and
nine-month periods ended January 28, 2000, was primarily a result of European
sales growth, due to increased headcount in the direct sales force, increased
indirect channel sales, increased shipments of filers, Cluster Failover
solutions, NetCache appliances and increased sales of add-on software licenses.
Asia Pacific net sales growth for the three and nine-month periods ended January
28, 2000, was also primarily driven by increased sales through resellers,
increased headcount in the direct sales force, increased shipments of filers,
NetCache appliances and increased sales of add-on software licenses, as compared
to the corresponding periods of the prior fiscal year.

        We cannot assure you that our net sales will continue to increase in
absolute dollars or at the rate at which they have grown in recent fiscal
periods.

        Gross Margin -- Gross margin increased slightly to 59.4% for the
three-months ended January 28, 2000 from 59.2% for the three-months ended
January 29, 1999. Gross margin decreased to 59.0% for the nine-months ended
January 28, 2000 from 59.2% for the nine-months ended January 29, 1999.

        Gross margin was favorably impacted by:

        -      increased licensing of add-on software products such as:
               multi-protocol, Cluster Failover, SnapMirror and SnapRestore
               associated with new filers shipped;

        -      growth in software subscription due primarily to a larger
               installed base;

        -      increased manufacturing efficiencies;

        -      the increase in product volume; and

        -      lower costs of key components.

        Gross margin was negatively impacted by sales price reductions on
storage products due to competitive pricing pressure from other storage vendors
and increased investments in customer service personnel in areas such as
logistics and professional services.

        Our gross margin has been and will continue to be affected by a variety
of factors, including:

        -      competition;

        -      product configuration;

        -      direct versus indirect sales;

        -      the mix and average selling prices of products, including
               software licenses;

        -      new product introductions and enhancements; and

        -      the cost of components and manufacturing labor.

        Sales and Marketing -- Sales and marketing expenses consist primarily of
salaries, commissions, advertising and promotional expenses and certain customer
service and support costs. Sales and marketing



                                       9
   11

expenses increased 102.7% to $40.2 million for the three-months ended January
28, 2000 from $19.8 million for the three-months ended January 29, 1999. Sales
and marketing expenses increased 92.2% to $99.6 million for the nine-months
ended January 28, 2000 from $51.8 million for the nine-months ended January 29,
1999. These expenses were 26.6% and 26.2% of net sales for the three-months
ended January 28, 2000 and January 29, 1999, respectively, and were 26.3% and
26.1%, respectively, of net sales for the nine-month periods then ended. The
increase in absolute dollars was primarily related to the continued worldwide
expansion and increased headcount growth of our sales and customer service
organizations, and increased commission expenses. During the quarter ended
January 28, 2000, we launched an advertising campaign, which also contributed to
absolute dollar increases in sales and marketing expenses. We expect to continue
to increase our sales and marketing expenses in an effort to expand domestic and
international markets, introduce new products, establish and expand new
distribution channels and increase product and company awareness. We believe
that our continued growth and profitability is dependent in part on the
successful expansion of our international operations, and therefore, have
committed significant resources to increase international sales.

        Research and Development -- Research and development expenses consist
primarily of salaries and benefits, prototype expenses, non-recurring
engineering charges and fees paid to outside consultants. Research and
development expenses increased 110.2% to $16.4 million for the three-months
ended January 28, 2000 from $7.8 million for the three-months ended January 29,
1999. These expenses represented 10.8% and 10.3% of net sales, respectively, for
the three-months ended January 28, 2000 and January 29, 1999. For the nine-month
periods, research and development expenses increased 99.4% to $41.1 million in
fiscal 2000 from $20.6 million in fiscal 1999, and represented 10.8% and 10.4%
of net sales, respectively, for those periods. Research and development expenses
increased in absolute dollars, primarily as a result of increased headcount,
ongoing support of current and future product development and enhancement
efforts, prototyping expenses and non-recurring engineering charges associated
with the development of new products and technologies. These new products
included the F700 series filers, the Cluster Failover solutions, the C700
family, new enterprise software offerings and data management tools with
SnapMirror, SnapRestore, SnapManager(TM) for Microsoft(R) Exchange and
SecureAdmin(TM). New caching product introductions included Netcache software
release 4.0 and Netcache 4.1, a streaming media appliance for Apple(R)
Quicktime(TM), Microsoft(R) Windows Media(TM) and RealNetworks(R) Real
System(TM) G2 users, delivering live broadcasting on the Internet. We believe
that our future performance will depend in large part on our ability to maintain
and enhance our current product line, develop new products that achieve market
acceptance, maintain technological competitiveness and meet an expanding range
of customer requirements. We intend to continuously expand our existing product
offerings and introduce new products and expect that such expenditures will
continue to increase in absolute dollars. For the three and nine-months ended
January 28, 2000 and January 29, 1999, no software development costs were
capitalized.

        General and Administrative -- General and administrative expenses
increased 106.1% to $5.5 million for the three-months ended January 28, 2000,
from $2.7 million for the three-months ended January 29, 1999. These expenses
represented 3.6% and 3.5% of net sales for the three-months ended for such
periods. For the nine-month periods, general and administrative expenses
increased 94.2% to $13.8 million in fiscal 2000 from $7.1 million in fiscal 1999
and represented 3.6% and 3.5% of net sales for the nine-months ended for such
periods. Increases in absolute dollars were primarily due to increased
headcount, expenses associated with initiatives to implement enterprise-wide
management information systems, increases in professional services, consulting
fees and outside service fees. We believe that our general and administrative
expenses will increase in absolute dollars as we continue to build our
infrastructure.

        Total Other Income, net -- Total other income, net, was $2.9 million and
$0.5 million for the three-months ended January 28, 2000 and January 29, 1999,
respectively. During the nine-months ended January 28, 2000, total other income,
net, was $7.2 million, as compared to $1.7 million in the corresponding period
of the prior year. The increase was due primarily to interest income earned on
the net proceeds from the March 1999 follow-on public offering, cash generated
from operations, and net proceeds from stock option exercises. The nine months
of fiscal 1999 included gains from foreign currency transactions as compared to
the nine months of fiscal 2000, where gains or losses from foreign transactions
have been largely mitigated primarily through our hedging program.

        Provision for Income Taxes -- Our effective tax rate was 35.5% for the
three and nine-month periods ended January 28, 2000 compared to 37.5% for the
three and nine-month periods ended January 29, 1999. The effective tax rates
differed from the U.S. statutory rate of 35% primarily due to state taxes
partially offset by earnings of foreign subsidiaries being taxed at lower rates.

CERTAIN RISK FACTORS

        Although we have experienced significant revenue growth in recent
periods, this growth may not be indicative of our future operating results. As a
result, we believe that period-to-period comparisons of our results of operation
are not necessarily meaningful and should not be relied upon as indicators of
future performance. Many of the factors that could cause our quarterly operating
results to fluctuate significantly in the future are beyond our control and
include the following:

        -      the level of competition in our target product markets;

        -      the size, timing, and cancellation of significant orders;

        -      product configuration and mix;

        -      market acceptance of new products and product enhancements;

        -      new product announcements or introductions by us or our
               competitors;

        -      deferrals of customer orders in anticipation of new products or
               product enhancements;

        -      changes in pricing by us or our competitors;

        -      our ability to timely develop, introduce and market new products
               and enhancements;

        -      supply constraints;

        -      technological changes in our target product markets;

        -      the levels of expenditure on research and development and
               expansion of our sales and marketing programs;

        -      seasonality; and

        -      general economic trends.

        In addition, sales for any future quarter may vary and accordingly be
inconsistent with our plans. We generally operate with limited order backlog
because our products are typically shipped shortly after orders are received. As
a result, product sales in any quarter are generally dependent on orders booked
and shipped in that quarter. Product sales are difficult to forecast because the
network file server market is rapidly evolving and our sales cycle varies
substantially from customer to customer.

        We conduct business internationally. International sales (including U.S.
exports) were approximately 31.0% and 28.9% of total net sales for the three and
nine-months ended January 28, 2000, respectively. Accordingly, our future
operating results could be materially adversely affected by a variety of
factors, some of which are beyond our control, including regulatory, political
or economic conditions in a specific country or region, trade protection
measures and other regulatory requirements and government spending patterns.

        Our international sales are denominated in U.S. dollars and in foreign
currencies. An increase in the value of the U.S. dollar relative to foreign
currencies could make our products more expensive and, therefore, potentially
less competitive in foreign markets. For international sales and expenditures
denominated in foreign currencies, we are subject to risks associated with
currency fluctuations. We hedge risks associated with foreign currency
transactions in order to minimize the impact of changes in foreign currency
exchange rates on earnings. We utilize forward contracts to hedge trade and
intercompany receivables and payables. All hedge contracts are marked to market
through earnings every period.

        Additional risks inherent in our international business activities
generally include, among others, longer accounts receivable payment cycles,
difficulties in managing international operations and potentially adverse tax
consequences. We cannot assure you that such factors will not materially
adversely affect our future international sales and, consequently, our operating
results.



                                       11
   13

        Although operating results have not been materially and adversely
affected by seasonality in the past, because of the significant seasonal effects
experienced within the industry, particularly in Europe, we cannot assure you
that our future operating results will not be adversely affected by seasonality.

        We believe that continued growth and profitability will require
successful expansion of our international operations and sales and therefore we
have committed significant resources to such expansion. In order to successfully
expand international sales in fiscal 2000 and subsequent periods, we must
strengthen foreign operations, hire additional personnel and recruit additional
international distributors and resellers. This will require significant
management attention and financial resources and could materially adversely
affect our operating results. To the extent that we are unable to effect these
additions in a timely manner, our growth, if any, in international sales will be
limited, and our operating results could be materially adversely affected. In
addition, we cannot assure you that we will be able to maintain or increase
international market demand for our products.

LIQUIDITY AND CAPITAL RESOURCES

        As of January 28, 2000, as compared to the April 30, 1999 balances, our
cash, cash equivalents and short-term investments increased by $63.0 million to
$290.1 million. Working capital increased by $104.9 million to $369.7 million.
We generated cash from operating activities totaling $52.7 million and $26.5
million for the nine-month periods ended January 28, 2000 and January 29, 1999,
respectively. Net cash provided by operating activities for the nine-month
period ended January 28, 2000 principally related to net income of $49.3
million, increases in accounts payable, income taxes payable, accrued
compensation and related benefits, deferred revenue and other accrued
liabilities, coupled with depreciation and amortization which are non-cash
expenses, partially offset by increases in accounts receivable, inventories,
prepaid expenses and other assets and deferred income taxes.

        We used $22.5 million and $11.6 million of cash during the nine-month
periods ended January 28, 2000 and January 29, 1999, respectively, for capital
expenditures. The increases were primarily attributed to upgrades of software
and computer equipment purchases and furniture and fixtures for the Sunnyvale
headquarters facility. We have used $53.0 million during the nine-month period
ended January 28, 2000 and received net proceeds of $2.7 million during the
nine-month period ended January 29, 1999, for net short-term investment
redemptions.

        During the nine-month period of fiscal 2000, we received back our $2.5
million deposit in connection with the $36.0 million operating lease. In
September 1999, we executed an agreement to acquire 9.9 acres of land in
Sunnyvale, California and the accompanying 178,996 square foot building. Under
terms of the agreement, we paid $2.7 million of the $23.4 million purchase price
as a nonrefundable deposit. The agreement allows us to assign our rights and
obligations to a third-party entity should we decide to enter into an operating
lease. We intend to assign our rights and obligations to a third-party entity
and enter into an operating lease provided we can obtain satisfactory leasing
terms.

        Financing activities provided $33.0 million and $12.0 million during the
nine-month periods ended January 28, 2000 and January 29, 1999, respectively.
The increase in cash provided by financing activities for the nine-months ended
January 28, 2000, compared to the corresponding period of the prior fiscal year,
was due to an increased quantity of stock options exercised at a higher average
exercise price and a greater number of employees participating in the employee
stock purchase plan.

        In November 1999, we executed an agreement to acquire 27.8 acres of land
in Sunnyvale, California and the accompanying 354,266 square feet of buildings.
Under terms of the agreement, we paid $3.0 million of the $61.0 million purchase
price as a nonrefundable deposit. In December 1999, we assigned our rights and
obligations under the agreement to a third-party entity and in exchange received
back our $3.0 million deposit in January 2000. We subsequently entered into a
$62.0 million operating lease for this property. Our lease payments will vary
based on LIBOR plus a spread. The lease is for five years and can be renewed for
two five-year periods, subject to the approval of the third-party entity. At the
expiration or termination of the lease, we have the option to either purchase
the property for $62.0 million, or arrange for the sale of the property to a
third party for at least $62.0 with a contingent liability for any



                                       12
   14

deficiency. If the property is not purchased or sold as described above, we will
be obligated for an additional lease payment of approximately $51.5 million. The
lease also requires us to maintain specified financial covenants with which we
were in compliance as at January 28, 2000.

        Excluding the commitment related to the aforementioned 178,996 square
foot property, which we intend to assign to third parties and account for as
operating leases, we currently have no significant commitments other than
commitments under operating leases. We believe that our existing liquidity and
capital resources, including the available amounts under our $5.0 million line
of credit, are sufficient to fund our operations for at least the next twelve
months.

YEAR 2000

        The Year 2000 issue refers to computer programs which use two digits
rather than four to define a given year and which therefore might read a date
using "00" as the year 1900 rather than the year 2000. As a result, many
companies' systems and software may need to be upgraded or replaced in order to
function correctly after December 31, 1999.

        Over the past year, we have been testing our computer systems and
applications to evaluate Year 2000 problems, executing remediation activities to
fix non-compliant systems and monitoring and testing products and systems. To
date, we have not experienced any problems complying with the Year 2000 issue
and have not been informed of any failures of our products from customers or
Year 2000 disruptions from third party vendors.

NEW ACCOUNTING STANDARDS

        In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which defines derivatives, requires that
all derivatives be carried at fair value, and provides for hedging accounting
when certain conditions are met. This statement is effective for all fiscal
quarters of fiscal years beginning after June 15, 2000. Although we have not
fully assessed the implications of this new statement, we do not believe
adoption of this statement will have a material impact on our consolidated
financial position, results of operations or cash flows.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        We are exposed to market risk related to fluctuations in interest rates
and in foreign currency exchange rates. We use certain derivative financial
instruments to manage these risks. We do not use derivative financial
instruments for speculative or trading purposes. All financial instruments are
used in accordance with management-approved policies.

Market Interest Risk

        Short-term Investments - As of January 28, 2000, we had short-term
investments of $58.6 million. These short-term investments consist of highly
liquid investments with original maturities at the date of purchase between
three and twelve months. These investments are subject to interest rate risk and
will decrease in value if market interest rates increase. A hypothetical 10
percent increase in market interest rates from levels at January 28, 2000, would
cause the fair value of these short-term investments to decline by an immaterial
amount. Because we have the ability to hold these investments until maturity we
would not expect any significant decline in value of our investments caused by
market interest rate changes. Declines in interest rates over time will,
however, reduce our interest income.

        Operating Lease Commitments - As of January 28, 2000, we have
outstanding lease commitments to a third-party entity under operating lease
agreements, which vary based on a monthly LIBOR rate plus a spread. However, a
hypothetical 10 percent decrease in interest rates would not have a material
impact on us. Increases in interest rates could, however, increase our rent
expenses associated with future lease payments. We do not currently hedge
against interest rate increases. However, our investment portfolio



                                       13
   15

offers a natural hedge against interest rate risk from our operating lease
commitments in the event of a significant increase in the market interest rate.

        The hypothetical changes and assumptions discussed above will be
different from what actually occurs in the future. Furthermore, such
computations do not anticipate actions that may be taken by management, should
the hypothetical market changes actually occur over time. As a result, the
effect on actual earnings in the future will differ from those described above.

        Foreign Currency Exchange Rate Risk - We hedge risks associated with
foreign currency transactions in order to minimize the impact of changes in
foreign currency exchange rates on earnings. We utilize forward contracts to
hedge against the short-term impact of foreign currency fluctuations on certain
assets and liabilities denominated in foreign currencies. All hedge instruments
are marked to market through earnings every period. We believe that these
forward contracts do not subject us to undue risk due to foreign exchange
movements because gains and losses on these contracts are offset by losses and
gains on the underlying assets and liabilities.

        All contracts have a maturity of less than one year and we do not defer
any gains and losses, as they are all accounted for through earnings every
period.

        The following table provides information about our foreign exchange
forward contracts outstanding on January 28, 2000, (in thousands):
