                            WIND RIVER SYSTEMS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.       Basis of Presentation


The accompanying condensed consolidated financial statements and related notes
of Wind River Systems, Inc. ("Wind River"or the "Company") are unaudited.
However, in the opinion of management, all adjustments (consisting only of
normal recurring adjustments) which are necessary for a fair presentation of the
financial position, results of operations and cash flows for the interim period
have been included. These condensed consolidated financial statements should be
read in conjunction with the audited consolidated financial statements and notes
thereto for the fiscal year ended January 31, 1999 included in Wind River's
Annual Report on Form 10-K. The results of operations for the three and six
months ended July 31, 1999 are not necessarily indicative of results to be
expected for the entire fiscal year, which ends on January 31, 2000 or for any
future period.


In accordance with the rules and regulations of the Securities and Exchange
Commission, unaudited condensed consolidated financial statements may omit or
condense certain information and disclosures normally required for a complete
set of financial statements prepared in accordance with generally accepted
accounting principles. However, Wind River believes that the notes to the
condensed consolidated financial statements contain disclosures adequate to make
the information presented not misleading.


The condensed consolidated financial statements include the accounts of Wind
River and its wholly-owned and majority-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.


Certain amounts in the fiscal 1999 condensed consolidated financial statements
have been reclassified to conform to the fiscal 2000 presentation.


2.       Write-Off of Investment


During the fiscal year ended January 31, 1999, Wind River paid $500,000 for a
10% interest in the common stock of XACT, Inc. ("XACT") that was accounted for
under the cost method. During April 1999, Wind River entered into an asset
purchase agreement with XACT pursuant to which Wind River acquired certain
office and other equipment from XACT and revised the terms of an existing
distribution agreement with XACT. Subsequently but not pursuant to the asset
purchase agreement, Wind River hired a significant number of XACT employees. As
a result of these events, Wind River believes the future operations and cash
flows of XACT have become uncertain and that Wind River's original investment is
not recoverable. Accordingly, Wind River has recognized a charge totaling
$500,000 for the difference between the carrying amount of its investment and
the net realizable value.


3.       RouterWare Acquisition


On June 30, 1999, Wind River completed the acquisition of RouterWare, Inc., a
California corporation. RouterWare develops and markets a suite of software
modules used in data communications products such as bridges, routers, gateways,
and remote access servers. Pursuant to the merger agreement, Wind River issued
730,923 shares of its common stock and reserved an additional 634,065 shares for
issuance upon exercise of outstanding employee stock options in exchange for all
of the outstanding shares of


                                       6


RouterWare common stock and shares issuable upon exercise of employee stock
options assumed in the merger. Wind River recorded this transaction using the
pooling-of-interests accounting method, and all financial data of Wind River
has been restated to include the historical financial information of
RouterWare.The results of operations previously reported by RouterWare and
the combined amounts for the fiscal years ended January 31, 1999 and 1998,
and for the quarters ended April 30, 1999 and 1998, are summarized as follows:

          Wind River                                 RouterWare
Fiscal year ended January 31, 1999         Fiscal year ended December 31, 1998
Fiscal year ended January 31, 1998         Fiscal year ended December 31, 1997
Fiscal year ended January 31, 1997         Fiscal year ended December 31, 1996

RouterWare's net loss of $77,000 for the period January 1, 1999 through
January 31, 1999 has been recorded as a decrease to stockholders' equity for
the quarter ended April 30, 1999.

4.       Revenue Recognition


Wind River adopted the provisions of Statement of Position ("SOP") 97-2,
"Software Revenue Recognition," as amended by SOP 98-4, "Deferral of the
Effective Date of Certain Provisions of SOP 97-2," effective February 1, 1998.
SOP 97-2 and SOP 98-4 provide guidance on recognizing revenue on software
transactions and supersede SOP 91-1.


In December 1998, the American Institute of Certified Public Accountants
("AICPA") released SOP 98-9, "Modification of SOP 97-2, `Software Revenue
Recognition' with Respect to Certain Transactions." SOP 98-9 amends SOP 97-2 to
require that an entity recognize revenue for multiple element arrangements by
means of the "residual method" when (1) there is Vendor-Specific Objective
Evidence ("VSOE") of the fair values of all the undelivered elements that are
not accounted for by means of long-term contract accounting, (2) VSOE of fair
value does not exist for one or more of the delivered elements, and (3) all
revenue recognition criteria of SOP 97-2 (other than the requirement for VSOE of
the fair value of each delivered element) are satisfied. The provisions of SOP
98-9 that extend the deferral of certain paragraphs of SOP 97-2 became effective
December 15, 1998. These paragraphs of SOP 97-2 and SOP 98-9 became effective
for transactions entered into in fiscal years beginning after March 15, 1999.
Retroactive application is prohibited. We have evaluated the requirements of SOP
98-9 and the effects, if any, on our current revenue recognition policies and
believe the effects of adopting SOP 98-9 will be immaterial to our financial
statements.

5.       Cash and Cash Equivalents, Investments and Restricted Cash


Cash equivalents consist of highly liquid investments with an original maturity
of three months or less. These investments consist of fixed income securities,
which are readily convertible to cash and are stated at cost, which approximates
fair value. Fair value is determined based upon the quoted market prices of the
securities as of the balance sheet date.


Investments with maturities greater than three months and less than one year are
classified as short-term investments. Investments with maturities greater than
one year are classified as long-term investments. Wind River accounts for its
investments, including equity securities, money market funds, municipal bonds,
U.S. government and agency obligations, corporate bonds and other debt
securities, in accordance with Statement of Financial Accounting Standards No.
("SFAS") 115, "Accounting for Certain Investments in Debt and Equity
Securities." Wind River determines the appropriate classification of its
marketable securities at the time of purchase and re-evaluates such
classification as of each balance sheet date. Wind River has classified all of
its investments as available-for-sale and carries such investments at fair
value, with unrealized gains and losses reported in accumulated other
comprehensive income component of stockholders' equity until disposition. Fair
value is determined based upon the quoted market prices of the securities as of
the balance sheet date. The cost of securities sold is based on the specific
identification method. Realized gains or losses and declines in value, if any,
judged to be other than temporary on available-for-sale securities are reported
in other income or expense.


Restricted cash consists of the investments held as collateral under the
operating lease of Wind River's headquarters and an accreting interest rate swap
agreement.


6.       Comprehensive Income


Comprehensive income is defined as the change in equity of a company during a
period from transactions and other events and circumstances excluding
transactions resulting from investments by owners and distributions to owners.
The primary difference between net income and comprehensive income, for Wind
River, results from foreign currency translation adjustments and unrealized
gains and losses on available-for-sale securities.


Comprehensive income for the three and six months ended July 31, 1999 and 1998
is as follows:




                                                          Three Months Ended               Six Months Ended

7.       Net Income Per Share


Wind River reports both basic net income per share, which is based on the
weighted-average number of common shares outstanding and diluted net income per
share, which is based on the weighted-average number of common shares
outstanding and all dilutive potential common shares outstanding. Potential
dilutive common shares consist of stock options and warrants (using the treasury
stock method) and convertible subordinated notes (using the if converted
method).


The following is a reconciliation of the number of shares used in the basic and
diluted earnings per share computations for the periods presented:




                                                           Three Months Ended            Six Months Ended

The effect of assumed conversion of the convertible subordinated notes is
anti-dilutive and is therefore excluded from the above computations. Options to
purchase approximately 4.5 million and 2.7 million common shares which were
outstanding at July 31, 1999 and 1998, respectively, were not included in the
calculation because the exercise prices were greater than the average market
price of common shares in each respective quarter and the effect would be
anti-dilutive. The exercise prices of these options ranged from $16.75 to $31.92
and $23.00 to $30.68 at July 31, 1999 and 1998, respectively.


8.       Treasury Stock


In June 1999, Board of Directors rescinded the $25.0 million increase in stock
repurchases authorized in April 1999 and Wind River's ongoing stock repurchase
program of $4.0 million per quarter. Wind River did not repurchase any shares
under either authorization during the second quarter ended July 31, 1999.


9.       Derivative Financial Instruments


Wind River enters into foreign currency forward exchange contracts to manage
exposure related to certain foreign currency transactions. Wind River does not
enter into derivative financial instruments for trading purposes. All
outstanding forward contracts at the end of a period are marked-to-market with
unrealized gains and losses included in other income, net, and thus are
recognized in income in advance of the actual foreign currency cash flows. Wind
River may, from time to time, adjust its foreign currency hedging position by
taking out additional contracts or by terminating or offsetting existing forward
contracts. These adjustments may result from changes in the underlying foreign
currency exposures or from fundamental shifts in the economics of particular
exchange rates. Gains and losses on terminated forward contracts, or on
contracts that are offset, are recognized in income in the period of contract
termination or offset. At July 31, 1999, Wind River had outstanding forward
contracts to hedge certain foreign currency transaction exposures primarily in
Japanese yen and certain European currencies. The difference between cost and
estimated fair value at July 31, 1999, was immaterial.


                                       9


On March 18, 1998, Wind River entered into an accreting interest rate swap
agreement (the "Swap Agreement") to reduce the impact of changes in interest
rates on its floating rate operating lease for its new corporate headquarters.
The Swap Agreement effectively changes Wind River's interest rate exposure on
its operating lease, which is at one month London interbank offering rate
("LIBOR"), to a fixed rate of 5.9%. At July 31, 1999, the notional amount of the
accreting interest rate swap was $28.5 million. The differential to be paid or
received under the Swap Agreement will be recognized as an adjustment to rent
expense related to the operating lease. The Swap Agreement matures at the same
time as the operating lease expires. The amounts potentially subject to credit
risk (arising from the possible inability of the counterparties to meet the term
of their contracts) are generally limited to the amounts, if any, by which the
counterparties' obligations exceed the obligations of Wind River.


10.      Recent Accounting Pronouncements


In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS 133
requires companies to record derivatives on the balance sheet as assets or
liabilities, measured at fair value. Gains or losses resulting from changes in
the fair values of those derivatives would be accounted for in current earnings
unless specific hedge criteria are met. The key criterion for hedge accounting
is that the hedging relationship must be highly effective in achieving
offsetting changes in fair value or cash flows. Wind River must formally
document, designate, and assess the effectiveness of transactions that receive
hedge accounting. In July 1999, the FASB issued SFAS 137, "Accounting for
Derivative Instruments and Hedging Activities Deferral of the Effective Date of
SFAS No. 133." SFAS 137 deferred the effective date of SFAS 133 until the first
fiscal quarter beginning after June 15, 2000. Wind River has not yet determined
the impact, if any, of adopting this statement.


11.      Segment and Geographic Information


Through the first six months of fiscal 2000, Wind River operated in one industry
segment --technology for embedded operating systems, and management used one
measurement of profitability for its business.


Wind River markets its products and related services to customers in the United
States, Canada, Europe and the Asia Pacific region. Internationally, Wind River
markets its products and services primarily through its subsidiaries and various
distributors. Revenues are attributed to geographic areas based on the country
in which the customer is domiciled. The distribution of revenues and assets by
geographic location is as follows:

12.      Chief Executive Officer Retirement Package


During the second quarter, Wind River incurred approximately $1.2 million
associated with the retirement package of the chief executive officer who
relinquished his responsibilities as president and chief executive officer as
of June 24, 1999. This non-recurring charge is included in general and
administrative expenses for the three months ended July 31, 1999.

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


Overview

Wind River develops, markets, supports and provides consulting services for
advanced software operating systems and development tools that allow customers
to create complex, robust, real-time software applications for embedded
computers. An embedded computer is a microprocessor that is incorporated into a
larger device and is dedicated to responding to external events by performing
specific tasks quickly, predictably and reliably. Wind River's flagship product,
Tornado II -TM-, enables customers to enhance product performance, standardize
designs across projects, reduce research and development costs and shorten
product development cycles.


During the fiscal year ended January 31, 1999, Wind River paid $500,000 for a
10% interest in the common stock of XACT, Inc. ("XACT") that was accounted for
under the cost method. During April 1999, Wind River entered into an asset
purchase agreement with XACT pursuant to which Wind River acquired certain
office and other equipment from XACT and revised the terms of an existing
distribution agreement with XACT. Subsequently but not pursuant to the asset
purchase agreement, Wind River hired a significant number of XACT employees. As
a result of these events, Wind River believes the future operations and cash
flows of XACT have become uncertain and that its original investment is not
recoverable. Accordingly, Wind River has recognized a charge totaling $500,000
for the difference between the carrying amount of its investment and the net
realizable value.


On June 30, 1999, Wind River completed the acquisition of RouterWare, Inc., a
California corporation. RouterWare develops and markets a suite of software
modules used in data communications products such as bridges, routers, gateways,
and remote access servers. Pursuant to the merger agreement, Wind River issued
730,923 shares of its common stock and reserved an additional 634,065 shares for
issuance upon exercise of outstanding employee stock options in exchange for all
of the outstanding shares of RouterWare common stock including shares issuable
upon exercise of employee stock options. Wind River recorded this transaction
using the pooling-of-interests accounting method and all financial data of Wind
River has been restated to include the historical financial information of
RouterWare.

Results of Operations

REVENUES

Total revenues for the three and six months ended July 31, 1999 were $39.6
million and $73.1 million, respectively, compared to $31.8 million and $58.5
million for the same periods in fiscal 1999. The increase in revenues for
both periods is due to increases in revenues of our products and services.

Revenue from the sale of products increased 21% and 20%, to $28.7 million and
$52.2 million, for the three and six months ended July 31, 1999, respectively,
compared to $23.7 million and $43.4 million for the same periods in fiscal 1999.
Product revenues primarily consist of development license fees and run-time
license fees. Wind River typically charges a one-time fee for development
licenses and OEM licenses and a run-time license fee for each copy of Wind
River's operating system embedded in the customer's product. The increase in
product revenues was due primarily to an increase in development license and OEM
licenses revenues, an increase in run-time license revenues, and revenues
related to the sale of RouterWare products. In addition, during the second
quarter, we began shipping Tornado for Managed Switches.


Services revenue increased 35% and 38%, to $10.9 million and $20.8 million, for
the three and six months ended July 31, 1999, respectively, compared to $8.1
million and $15.1 million for the same periods in the prior fiscal year. The
increase was primarily due to increases in revenue from (1) maintenance support
agreements, both new and recurring, (2) training resulting from the increase in
Wind River's installed base of Tornado -TM- software development environment and
software applications provided to customers; and (3) professional services.
These increases were partially offset by a decline in revenues from engineering
services.


Total revenues from international sales for the three and six months ended
July 31, 1999 were $13.2 million and $26.5 million, respectively, compared to
$9.5 million and $18.4 million for the same periods in the prior fiscal year.
The increase of 39% and 44% for the three and six months ended July 31, 1999
was primarily due to increased demand for our products and services in Japan
and Europe. International revenues accounted for 33% and 36% of total
revenues for the three and six months ended July 31, 1999, compared to 30%
and 31% for the same periods in the prior fiscal year. We expect
international sales to continue to represent a significant portion of
revenues, although the actual percentage may fluctuate from period to period.
Wind River's international sales are denominated in the local currencies, and
an increase in the relative value of the dollar against such currencies would
reduce our revenues and backlog in dollar terms or make our products more
expensive and, therefore, potentially less competitive in foreign markets.
Wind River actively monitors its foreign currency exchange exposure and to
date such exposures have not had a material impact on our results of
operations. We enter into forward contracts to hedge the short-term impact of
foreign currency fluctuations. In recent years, economic uncertainty and
related weakening of certain foreign currencies against the dollar has
occurred. These factors could adversely affect our future sales, which could
have a material adverse effect on our business, results of operations and
financial condition. Revenues from Asia Pacific sources including Japan
represented 17% and 19% of international revenues for the three and six
months ended July 31, 1999, compared to 12% and 14% for the same periods in
the prior fiscal year. See "Additional Risk Factors that may affect Future
Results of Operations-Our International Business Activities Subject Us to
Risks That Could Adversely Affect Our Business."

                                       13


COSTS OF REVENUES

The overall cost of products and services as a percentage of total revenues
was 19% and 18% for the three and six month periods ended July 31, 1999,
compared to 18% for the same periods of fiscal 1999. Product-related cost of
sales as a percentage of product revenues was 10% and 9% for the three and
six month period ended July 31, 1999, compared to 10% for each of the
corresponding periods of the prior fiscal year. Product-related costs consist
primarily of salaries and benefits for production employees, product media,
royalty payments to third parties for the use of their software and
documentation and packaging. Wind River's cost of revenue as a percentage of
product revenues may be affected in the future by the amortization of
purchased technology and distribution rights related to the introduction of
new products, including Tornado II, Tornado for Embedded Internet products
and Tornado for Managed Switches and by the royalty payments to other third
parties for sales related to their products.

Service related cost of revenue as a percentage of service revenue was 43%
for each of the three and six month period ended July 31, 1999, compared to
40% for the same periods in fiscal 1999. Service related costs consist
primarily of personnel related costs associated with providing services to
customers and the infrastructure to manage a services organization as well as
costs to recruit, develop, and retain services professionals. The increase in
costs of service revenues is due to our investment in developing new services
offerings and the addition of our new professional services organization. We
expect that customer services costs will increase in absolute dollars as we
continue to increase our customer support staff, customer support
capabilities and professional services organization.

OPERATING EXPENSES

Selling and marketing expenses were $14.3 million and $26.6 million for the
three and six months ended July 31, 1999, compared to $11.2 million and $21.2
million for the same periods in the prior fiscal year. As a percentage of
total revenue, selling and marketing expenses were 36% for both the three and
six months ended July 31, 1999, compared to 35% and 36% for the corresponding
periods in the prior fiscal year. The increase in absolute dollars resulted
primarily from the growth in the number of sales and marketing personnel and
field engineers and related costs and increases in expenses related to
marketing and advertising programs including third party marketing costs for
product introductions and promotions. During the six months ended July 31,
1999, Wind River continued its introduction of Tornado II to the marketplace,
and first customer shipment took place in the second quarter of fiscal 2000.
We expect that sales and marketing expenses will continue to increase in
absolute dollars as we continue to expand our sales and marketing staff.

Product development and engineering expenses were $7.3 million and $13.8
million for the three and six months ended July 31, 1999, compared to $4.7
million and $8.9 million for the same periods in the prior fiscal year. As a
percentage of total revenue, product development and engineering expenses
were 18% and 19% for the three and six months ended July 31, 1999, compared
to 15% for both the corresponding periods in the prior fiscal year. The
increase in product development and engineering expenses is primarily due to
the increase in staff and associated support for engineers to expand and
enhance Wind River's product line, including the costs associated with
integrating the XACT engineering team Wind River hired in April 1999 and with
the additional engineering staff through the acquisition of RouterWare in
June 1999. In addition, Wind River had $148,000 of funded research and
development for the second quarter of fiscal 2000. We believe that product
development and engineering expenses will continue to increase in absolute
dollars as we continue to invest in the development of new products,
technologies, applications and product enhancements.

                                       14


General and administrative expenses were $4.6 million and $7.1 million for
the three and six months ended July 31, 1999, compared to $1.9 million and
$3.5 million, respectively, for the corresponding periods in the prior fiscal
year. As a percentage of total revenue, general and administrative expenses
were 12% and 10% for the three and six months ended July 31, 1999, compared
to 6% for each of the corresponding periods in the prior fiscal year. The
increase during the second quarter was due primarily to (1) a non-recurring
charge of $1.2 million incurred for the retirement package for our former
chief executive officer, (2) the costs incurred for the acquisition of
RouterWare of approximately $930,000 and (3) the growth in worldwide
staff and infrastructure investments in the areas of information systems,
finance and administration. The increase for the first six months was
attributed, in addition to the above, to (1) the write-off of a distribution
agreement with XACT in which XACT is unable to complete the development of
their product that is subject to the distribution agreement; and (2) the
costs associated with hiring the XACT employees, acquiring equipment and
other assets of XACT and revising a second distribution agreement for another
product with XACT. We believe that general and administrative expenses will
continue to increase in absolute dollars excluding the non-recurring charges
related to the chief executive officer retirement package, RouterWare and
XACT as it continues to invest in worldwide staff and infrastructure in the
areas of information systems, finance and administration.

OTHER INCOME AND EXPENSES

Interest income was $3.8 million and $7.5 million for the three and six
months ended July 31, 1999, respectively, compared to $3.5 million and $6.6
million for the same periods in the prior fiscal year. The increase in
interest income was primarily due to larger cash and cash equivalent,
investment portfolio and restricted cash accounts compounded with higher
interest rates. Total cash and cash equivalent, investment and restricted
cash at July 31, 1999 and 1998 was approximately $268 million and $232
million, respectively.

Interest expense and other, net was $2.3 million and $5.4 million for the three
and six months ended July 31, 1999, compared to $2.3 million and $4.5 million
for the same periods in the prior fiscal year. Wind River pays interest on the
5.0% Convertible Subordinated Notes, due in 2002 and maturities of certain
issuance costs associated with these Notes. The interest on the Notes is payable
on February 1 and August 1 of each year commencing February 1, 1998. The Notes
mature on August 1, 2002.


During the fiscal year ended January 31, 1999, Wind River paid $500,000 for a
10% interest in the common stock of XACT that was accounted for under the cost
method. During April 1999, Wind River entered into an asset purchase agreement
with XACT pursuant to which Wind River acquired certain office and other
equipment from XACT and revised the terms of an existing distribution agreement
with XACT. Subsequently but not pursuant to the asset purchase agreement, Wind
River hired a significant number of XACT employees. As a result of these events,
Wind River believes the future operations and cash flows of XACT have become
uncertain and that its original investment is not recoverable. Accordingly, Wind
River has recognized a charge totaling $500,000 for the difference between the
carrying amount of its investment and the net realizable value.


                                       15


PROVISION FOR INCOME TAXES

The effective tax rate for the three and six months ended July 31, 1999 was
42.8% and 40.0%, compared to 38.7% and 39.1% for the same periods in the
prior fiscal year. The overall changes in the effective tax rates result
primarily from certain non-deductible acquisition costs related to
RouterWare. In addition, the changes are attributed to the difference between
foreign and domestic tax rates, the ratio of foreign taxable income to
domestic taxable income, varying levels of available research and development
credits, and varying levels of tax-exempt interest income.

LIQUIDITY AND CAPITAL RESOURCES

At July 31, 1999, Wind River had working capital of approximately $76.9
million and cash and investments, excluding restricted cash, of approximately
$231.6 million, which include investments with maturities greater than one
year of $148.2 million. The decrease in long-term investments of $10.5
million from January 31, 1999 was primarily due to transfer of funds held
from long-term securities to short-term investments and cash equivalents. The
decrease in long-term investment was partially offset by an approximately
$8.0 million increase in the market value of our equity securities.

During the first six months of fiscal 2000, Wind River's operating activities
provided net cash of $23.7 million due primarily to net income adjusted for
depreciation and amortization, and changes in accounts receivable, accrued
compensation and income taxes payable. These sources of cash were partially
offset by the changes in prepaid and other assets and deferred revenue.

During the first six months of fiscal 2000, investing activities used net
cash of $6.3 million due primarily to purchases of investments, the
acquisition of equipment, and changes in restricted cash. These uses of cash
were partially offset by cash provided relating to the sales of investments.
As Wind River transitioned its investment portfolio from long-term to
short-term investments and cash equivalents, our long-term investments
decreased by $10.5 million. During the six months ended July 31, 1999, Wind
River purchased fixed assets of $5.6 million including $1.8 million for its
new financial databases, applications, and reporting systems. Restricted cash
increased primarily due to the increased collateral funding required for the
operating lease of Wind River's headquarters. The collateral consists of
direct obligations of the United States government, with the majority being
long-term securities.

Wind River's financing activities used net cash of $396,000 due primarily for
stock repurchases of approximately $4.0 million in the first quarter
substantially offset by cash provided by the issuance of common stock from
employee stock option exercises and a purchase of stock by a member of the
Board of Directors. During the six months ended July 31, 1999, Wind River
repurchased as part of its systematic stock repurchase program, 165,000
shares of its common stock at a cost of approximately $4.0 million. In June
1999, the Board of Directors rescinded all stock repurchase authorizations
and we have not made any repurchases since March 17, 1999.

In fiscal 1998, Wind River entered into an operating lease agreement for a new
headquarters facility to be constructed on land owned by Wind River in Alameda,
California. The lessor of the building funded the costs of the building
construction directed by the Company. The building construction was completed in
August 1999 and the final balance on the commitment amounted to $32.4 million.
Operating lease payments commenced upon completion of construction and will vary
based on the London interbank offering rate ("LIBOR".)


                                       16


On March 18, 1998, Wind River entered into an accreting interest rate swap
agreement to reduce the impact of changes in interest rates on its floating rate
operating lease for its new corporate headquarters. This agreement effectively
changes Wind River's interest rate exposure on its operating lease, which is
based on one month LIBOR to a fixed rate of 5.9%. At July 31, 1999, the notional
amount of the accreting interest rate swap was $28.5 million. The differential
to be paid or received under this agreement will be recognized as an adjustment
to rent expense related to the operating lease. The swap agreement matures at
the same time as the operating lease expires. The amounts potentially subject to
credit risk (arising from the possible inability of counterparties to meet the
term of their contracts) are generally limited to the amounts, if any, by which
the counterparties' obligations exceed the obligations of Wind River. Wind River
manages potential counterparty credit risk prior to entering into transactions
by requiring that all counterparties have at least a AA Standard and Poor's, or
Moody's equivalent, long-term senior debt rating.


In connection with the lease, Wind River is obligated to enter into a lease of
its land in Alameda, California with the lessor of the building at a nominal
rate and for a term of 55 years. If Wind River terminates or does not negotiate
an extension of the building lease, the ground lease converts to a market rental
rate. The lease provides Wind River with the option at the end of the lease term
to either acquire the building at the lessor's original cost or arrange for the
building to be acquired. Wind River has guaranteed the residual value associated
with the building to the lessor of approximately 82% of the lessor's funding
obligation. Wind River is also required to maintain fixed income securities with
a custodian as a deposit to secure the performance of its obligations under the
lease. In addition, under the terms of the lease, Wind River must maintain
compliance with certain financial covenants. As of July 31, 1999, Wind River was
in compliance with these covenants. Management believes that the contingent
liability relating to the residual value guarantee will not have a material
adverse effect on Wind River's financial condition or results of operations.


Wind River has an investment portfolio of fixed income securities that are
classified as available-for-sale securities. These securities, like all fixed
income instruments, are subject to interest rate risk and will decline in value
if market interest rates increase. Wind River attempts to limit this exposure by
investing primarily in high-grade securities.


Management believes Wind River's working capital and the cash flow from
operations will be sufficient to meet its working capital requirements for
planned expansion, product development and capital expenditures for the next
twelve months.


                                       17


"YEAR 2000" ISSUES

Many currently installed computer systems and software products include coding
to accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish dates prior to January 1,
2000, from dates on and after January 1, 2000. As a result, in approximately
four months, computer systems and/or software used by many companies will need
to be upgraded to comply with such "Year 2000" requirements. Systems that do not
properly recognize such information could generate erroneous data or cause a
system to fail. Significant uncertainty exists in the software industry
concerning the potential effects associated with such compliance.


Wind River has conducted Year 2000 compliance reviews for current versions of
its products. The review includes assessment, implementation, validation testing
and contingency planning. Although Wind River believes the most current releases
of its products will neither cease to perform nor generate incorrect or
ambiguous data or results solely due to a change in date on or after January 1,
2000 and will calculate any information dependent on such dates in the same
manner, and with the same functionality, data integrity and performance as such
products on or before December 31, 1999 (collectively "Year 2000 Compliance"),
Wind River provides no assurance that its software products contain all the
necessary software routines and programs for the accurate calculation, display,
storage and manipulation of data involving dates. Failure of Wind River's
software products to contain all the necessary software routines and programs
for the accurate calculation, display, storage and manipulation of data
involving dates would have a material adverse effect on Wind River's business,
financial condition and results of operation. The majority of Wind River's
products are combined by its customers with other software programs or hardware
devices not provided by Wind River. Such combination with other products that
are not Year 2000 Compliant or modifications of Wind River's products by its
customers may introduce Year 2000 Compliance issues for its customers. Wind
River's customers' inability to remedy their own Year 2000 Compliance issues
could affect their demand for Wind River's products, which may materially and
adversely affect Wind River's business, financial condition and results of
operations. Wind River continues to respond to customer concerns about prior
versions of Wind River's products on a case-by-case basis. For certain older
versions of Wind River's products which may not be Year 2000 compliant, Wind
River is providing a patch to bring the product into compliance. With respect to
certain third party products included in Wind River's product offerings that may
not be Year 2000 compliant, Wind River is working with software vendors to bring
the products into compliance.


To address Year 2000 issues, Wind River has an ongoing program designed to
address the most critical Year 2000 items that would affect its products, its
worldwide business systems, and the operations of research and development,
finance, sales and marketing, manufacturing, and human resources. Assessment and
remediation efforts regarding these critical items are proceeding in parallel.


Wind River has tested software obtained from third parties that is integrated
into or with Wind River's products, and seeks assurances from vendors that
licensed software is Year 2000 Compliant. Despite testing by Wind River, current
customers and potential customers, and assurances from developers of products
incorporated into Wind River's products, such products may contain undetected
errors or defects associated with Year 2000 date functions. Known or unknown
errors or defects in Wind River's products or third party products may result in
delay or loss of revenue, diversion of development resources, damage to Wind
River's reputation, or increased service and warranty costs. The occurrence of
any of the foregoing could materially adversely affect Wind River's business,
financial condition and results of operations.


Wind River is working with critical suppliers to determine that such suppliers'
operations and the products and services they provide Wind River are Year 2000
Compliant or to monitor their progress


                                       18


towards Year 2000 Compliance. Wind River has requested its critical suppliers
to complete a questionnaire that provides information regarding Year 2000
Compliance. The suppliers rate themselves as currently Year 2000 Compliant or
are engaged in programs to become Year 2000 Compliant. Wind River will
continue to monitor the status of suppliers who have not completed their Year
2000 Compliance programs. Wind River has received information from its
largest customers regarding Year 2000 Compliance. The customers state that
they will not incur any business interruptions related to Year 2000
Compliance issues. As is the case with other software companies, if its
current or future outside customers or suppliers fail to achieve Year 2000
Compliance or if they divert technology expenditures to address their own
Year 2000 Compliance problems, Wind River's business, financial condition or
results of operations could be materially adversely affected.

In 1997, Wind River commenced a worldwide financial business and production
systems replacement project that uses software primarily from Oracle. The new
systems are targeted at bringing Wind River's business and production computer
systems into Year 2000 Compliance. Wind River anticipates its financial and
production systems will be operational in the fourth quarter of fiscal 2000. In
January 1998, Wind River initiated an analysis of the condition of Year 2000
readiness for the programs it uses for internal development. Wind River will
modify or replace programs that were determined not to be Year 2000 Compliant.
Wind River believes the software and hardware it uses internally or will have
installed for internal use will comply with Year 2000 requirements and is not
aware of any material operational issues or costs associated with preparing its
internally used software and hardware for the Year 2000. However, Wind River
provides no assurances that it will not experience serious, unanticipated
negative consequences, including material costs caused by undetected errors or
defects in the technology used in its internal systems. The occurrence of any of
the foregoing could have a material adverse effect on Wind River's business,
operating results or financial condition.


Wind River has funded its Year 2000 Compliance review from operating cash
flows and, except for its new financial reporting system, has not separately
accounted for these costs. Wind River will incur additional amounts related
to the Year 2000 Compliance review including administrative personnel to
manage the review, outside contractors to provide technical advice and
technical support for its products, product engineering and customer
satisfaction. Excluding the implementation of its financial reporting system,
we believe that we have completed approximately 90% of the work required to
obtain Year 2000 Compliance. We expect to incur costs of approximately $4.0
million to implement its financial reporting system. As of July 31, 1999,
Wind River has incurred $2.9 million for the implementation. Wind River's
Year 2000 budget will be modified as necessary to address correction of any
additional systems identified to be non-compliant. However, management does
not anticipate that Wind River will incur other significant operating
expenses or be required to invest heavily in computer systems improvements to
be Year 2000 Compliant.

Wind River is currently developing contingency plans to be implemented as part
of its efforts to identify and correct Year 2000 problems affecting its internal
systems. Wind River expects to complete its contingency plans by the fourth
quarter of fiscal 2000. Depending on the systems affected, these plans could
include accelerated replacement of affected equipment or software, short to
medium-term use of backup equipment and software, increased work hours for
Company personnel or use of contract personnel to correct (on an accelerated
schedule) any Year 2000 problems that arise or to provide manual workarounds for
information systems, and similar approaches. If Wind River is required to
implement any of these contingency plans, it could have a material adverse
effect on Wind River's financial condition and results of operations.


Wind River's ability to achieve Year 2000 Compliance and the level of
incremental costs associated therewith could be adversely impacted by, among
other things, the availability and cost of programming


                                       19


and testing resources, vendors' ability to modify propriety software, and
unanticipated problems identified in the ongoing compliance review. Such
failures could have a material adverse affect on Wind River's business,
financial condition and results of operations.

EURO CURRENCY

On January 1, 1999, several member countries of the European Union
established fixed conversion rates between their sovereign currencies and
adopted the Euro as their new common legal currency. Since that date, the
Euro has traded on currency exchanges. The legacy currencies will remain
legal tender in the participating countries for a transition period between
January 1999 and January 1, 2002. During the transition period, non-cash
payments can be made in the Euro, and parties can elect to pay for goods and
services and transact business using either the Euro or a legacy currency.
Between January 1, 2002 and July 1, 2002, the participating countries will
introduce Euro notes and coins and withdraw all legacy currencies from
circulation. The Euro conversion may affect cross-border competition by
creating cross-border price transparency. Wind River is assessing its pricing
and marketing strategy in order to insure that it remains competitive in a
broader European market and is reviewing whether certain existing contracts
will need to be modified. Wind River has assessed the ability of information
technology systems to allow for transactions to take place in both the legacy
currencies and the Euro and the eventual elimination of the legacy currencies
and believes that its information technology systems will not be affected by
the transition to the Euro. Wind River does not presently expect that
introduction and use of the Euro will materially affect Wind River's foreign
exchange exposures and hedging activities or will result in any material
increase in costs to Wind River. Wind River's currency risk and risk
management for operations in participating countries may be reduced as the
legacy currencies are converted to the Euro. Final accounting, tax and
governmental, legal and regulatory guidance is not available. Wind River will
continue to evaluate issues involving introduction of the Euro. Based on
current information and our current assessment, we do not expect that the
Euro conversion will have a material adverse effect on our business,
financial condition or results of operations.

ADDITIONAL RISK FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS


WIND RIVER'S BUSINESS FACES SIGNIFICANT RISKS. IF ANY OF THE EVENTS OR
CIRCUMSTANCES DESCRIBED IN THE FOLLOWING RISKS ACTUALLY OCCURS, WIND RIVER'S
BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS COULD BE MATERIALLY AND
ADVERSELY AFFECTED. THESE RISKS SHOULD BE READ IN CONJUNCTION WITH THE OTHER
INFORMATION SET FORTH IN THIS REPORT.


NUMEROUS FACTORS MAY CAUSE OUR REVENUES AND OPERATING RESULTS TO FLUCTUATE
SIGNIFICANTLY FROM PERIOD TO PERIOD


Our revenues and operating results have fluctuated significantly in the past and
may continue to do so in the future. If our quarterly or annual operating
results do not meet the expectations of securities analysts and investors, the
market price of our common stock could decline significantly. A number of
factors, many of which are outside our control, may cause or contribute to these
fluctuations, including:


- -   the amount and timing of orders we receive
- -   changes in the length of our products' sales cycles, which increase as our
    customers' purchase decisions become more strategic and are made at higher
    management levels
- -   the success of our customers' products from which we derive our royalty
    revenues


                                       20


- -   the mix of our revenues from the sale of services as compared to
    products, which have higher margins
- -   our ability to control our operating expenses, which we anticipate will
    continue to increase during the current fiscal year
- -   our ability to continue to develop, introduce and ship competitive new
    products and product enhancements quickly
- -   announcements, new product introductions and price reductions by our
    competitors
- -   our ability to manage costs for fixed-price consulting engagements
- -   changes in business cycles that affect the markets in which we sell our
    products;
- -   economic conditions generally and in international markets, which
    historically have provided a significant portion of our revenues
- -   foreign currency exchange rates


In addition, we often recognize a significant portion of our quarterly
revenues from orders we receive and ship in the last month of the quarter
and, as a result, we may not be able to forecast our revenues until late in
the period. Further, our customers historically have purchased more of our
products in our fourth fiscal quarter than in other quarters. A decrease in
orders is likely to adversely and disproportionately affect our operating
results, because a significant portion of our expenses are fixed and are
based, in part, on our expectations of future revenues. Therefore, we have a
limited ability to reduce expenses in response to a shortfall in anticipated
revenues. We believe that period-to-period comparisons of our operating
results may not be meaningful, and should not be relied on as an indication
of our future performance.

WE ONLY RECENTLY BEGAN TO FOCUS ON OFFERING SOFTWARE CONSULTING SERVICES AND
THEREFORE, MAY NOT BE AS EXPERIENCED IN THIS BUSINESS AS OTHERS. TO BE
SUCCESSFUL WITH OUR PROFESSIONAL SERVICES BUSINESS, WE MUST OVERCOME SEVERAL
FACTORS INCLUDING:

- -   Services contracts can be fixed-price commitments and if our cost of
    performing the services consistently and significantly exceeds the amount
    the customer has agreed to pay, it could materially adversely affect our
    business, financial condition and results of operations.
- -   Our cost of services personnel and certified consultants is high which
    results in lower gross margins than our software business.

If we cannot accurately estimate our costs and achieve milestones during
consulting engagements and retain competent services personnel, our business,
financial condition and results of operations could be materially adversely
affected.

OUR OPERATING RESULTS ARE DEPENDENT UPON SALES OF A SMALL NUMBER OF PRODUCTS

Revenue from sales of our Tornado and VxWorks family of products and services
has historically accounted for substantially all of our revenue, and we expect
this concentration will continue in the foreseeable future. Any reduction in the
demand for Tornado or VxWorks family of products and services could materially
adversely affect our operating results and cause the price of our common stock
to decline.


                                       21


A SIGNIFICANT PORTION OF OUR REVENUE IS DEPENDENT UPON THE MARKET ACCEPTANCE OF
OUR CUSTOMERS' PRODUCTS

One of the key components of our business strategy is to increase revenue
through royalty fees for each copy of our operating system embedded in the
products our customers sell. Success of this strategy depends upon our ability
to successfully negotiate royalty agreements with our customers and their
successful commercialization of the underlying products. To the extent that our
customers are not successful, for whatever reason, our revenues may be reduced
significantly and our business, financial condition and results of operations
could be materially adversely affected.

OUR FAILURE TO RESPOND QUICKLY TO RAPID TECHNOLOGICAL CHANGE WITH PRODUCT
OFFERINGS WILL ADVERSELY AFFECT OUR ABILITY TO COMPETE

The market for embedded real-time software is characterized by ongoing
technological developments, evolving industry standards, and rapid changes in
customer requirements. Our success depends upon our ability to adapt and respond
to these changes. We must continuously update our existing products to keep them
current with customer needs, and must develop new products to take advantage of
new technologies, emerging standards, and expanding customer requirements that
could render our existing products obsolete. Additionally, we have from time to
time experienced delays in the development of new products and the enhancement
of existing products, including, most recently, a delay in the development of
our new product "Tornado for Managed Switches." Such delays are commonplace in
the software industry. Furthermore, if we cannot achieve design wins with key
customers, our business will be significantly affected. Once a customer has
designed the product with a particular operating system, that customer typically
is reluctant to change its supplier, due to the significant costs associated
with selecting a new supplier. If we cannot, for technical, legal, financial or
other reasons, adapt or respond in a cost effective and timely manner to
changing market conditions or customer requirements, our business and operating
results would suffer.

IF OUR NEW PRODUCT LINES ARE NOT ACCEPTED, OUR BUSINESS WOULD BE MATERIALLY
ADVERSELY AFFECTED

Our future success is substantially dependent upon whether our new product lines
gain wide market acceptance. We are continuously engaged in product development
for new or changing markets. In particular, we have invested significant time
and effort, together with a consortium of industry participants, in the
development of I2O, a new specification that is intended to create an open
standard set of interface specifications for high performance Input Output (I/O)
systems. In parallel with this effort, we have developed IxWorks, a real-time
operating system for use in conjunction with the I2O specification. The success
of the I2O specification and the IxWorks product line depends heavily on its
adoption by a broad segment of the industry.

We have also spent, and continue to spend, substantial time and financial
resources to develop software for Internet appliances and Internet
infrastructure, including "Tornado for Managed Switches." The commercial
Internet market has only recently begun to develop, is rapidly changing and
is characterized by an increasing number of new entrants with competitive
products. Moreover, there are an increasing number of new Internet protocols
to which our products must be ported. It is unclear which of these competing
protocols ultimately will achieve market acceptance. If the protocols upon
which our Internet products are based ultimately fail to be widely adopted,
our business, financial condition and results of operations may be materially
and adversely affected.

                                       22


It is difficult to predict whether demand for any of these products will develop
or increase in the future. If these markets, or any other new market we target
in the future, fail to develop, develop more slowly than anticipated or become
saturated with competitors, if our products are not developed in a timely
manner, or if our products and services do not achieve or sustain market
acceptance, our business, financial condition and results of operations would
suffer.


WE FACE INTENSE COMPETITION, WHICH COULD ADVERSELY AFFECT OUR ABILITY TO
MAINTAIN OR INCREASE SALES OF OUR PRODUCTS


The embedded real-time software industry is highly competitive. We believe that
our principal competition comes from companies that develop real-time operating
systems in-house rather than purchase such systems from independent software
vendors such as Wind River. We also compete with other independent software
vendors, including Accelerated Technology, Inc., Integrated Systems, Inc.,
Mentor Graphics, Inc., Microsoft Corporation, Microware Systems Corporation, QNX
Software Systems, Ltd., and Sun Microsystems, Inc. In addition, hardware or
other software vendors could seek to expand their product offerings by designing
and selling products that directly compete with or adversely affect sales of our
products. Many of our existing and potential competitors have substantially
greater financial, technical, marketing and sales resources. As a result, they
may be able to respond more quickly to new or emerging technologies and changes
in customer requirements, or to devote greater resources to the development,
promotion, sale and support of their products. Moreover, our competitors may
foresee the course of market developments more accurately than we do and could
in the future develop new technologies that compete with our products or even
render our products obsolete. Although we believe we presently have certain
technological and other advantages over our competitors, realizing and
maintaining such advantages will require a continued high level of investment in
research and development, marketing and customer service and support. In
addition, competitive pressures could cause us to reduce the prices of our
products, run-time royalties and services, which would result in reduced profit
margins. If we are unable to compete successfully, our business, financial
condition and results of operations would be materially and adversely affected.


ACQUISITIONS MAY DISRUPT OUR BUSINESS, DILUTE OUR STOCKHOLDERS AND INCREASE OUR
INDEBTEDNESS


As part of our business strategy, we have acquired or made investments in
several businesses, products and technologies that complement ours, and we
anticipate that we will continue to do so in the future. We may experience
difficulties integrating an acquired company's operations into ours. As a
result, we may divert management attention to the integration that would
otherwise be available for the ongoing development of our business. Acquisitions
have additional inherent risks, including:


- -   difficulties assimilating acquired operations, technologies or products
- -   unanticipated costs
- -   adverse effects on relationships with customers, suppliers and employees


We may not be successful in integrating the businesses, products, technologies
or personnel we acquire, and our failure to do so could materially adversely
affect our business, financial condition and results of operations. Similarly,
we cannot guarantee that our investments will yield a significant return if any.
In addition, to finance acquisitions, we may issue equity securities, which may
dilute our earnings per share, or incur significant indebtedness, which could
materially adversely affect our results of operations.


                                       23


Certain of our acquisitions have been accounted for under the
pooling-of-interests accounting method and financial reporting rules. To qualify
these acquisitions as pooling-of-interests for accounting purposes, certain
criteria established in opinions by the Accounting Principles Board and
interpreted by the Financial Accounting Standards Board and the Securities and
Exchange Commission must be met. These opinions are complex and the
interpretation of them is subject to change. In addition, the availability of
pooling-of-interests accounting treatment depends in part upon circumstances and
events occurring after the acquisition. The failure of an acquisition to qualify
for pooling-of-interests accounting treatment for financial reporting purposes
for any reason would materially adversely affect our reported earnings and
likely, the price of our common stock.


WE SELL A SIGNIFICANT PORTION OF OUR PRODUCTS TO CUSTOMERS DEPENDENT UPON
GOVERNMENT FUNDING, WHICH MAY NOT CONTINUE TO BE AVAILABLE


We have derived a portion of our revenues historically from sales of systems
built to the VME (versabus module eurocard) standard. These systems typically
are used in high cost, low volume applications, including military,
telecommunications, space and research applications. Although we believe that
revenues from sales of products designed for embedded systems applications
(non-VME customers) will account for an increasing percentage of our revenues in
the future, we do expect revenues from the VME market to continue to be
significant for the foreseeable future. Academic institutions and defense
industry participants, which generate most of our VME revenues, are dependent on
government funding. Any unanticipated future termination of government funding
of VME customers could have a material adverse effect on our business, financial
condition and results of operations.


FAILURE TO MANAGE OUR GROWTH COULD SIGNIFICANTLY STRAIN OUR PERSONNEL AND OTHER
RESOURCES


We have experienced, and expect to continue to experience, significant growth in
our headcount and in the scope, complexity and geographic reach of our
operations. Our future success will depend, in part, on our ability to continue
to integrate new operations and personnel. To support this expansion, we must
continue to hire, train, motivate and manage our workforce and improve our
management controls, reporting systems and procedures. Our current and planned
personnel, systems, procedures and controls may not be adequate to support our
future operations. Failure to forecast our needs accurately or to manage our
growth appropriately could materially adversely affect our business, financial
condition and results of operations.


WE DEPEND ON OUR KEY PERSONNEL AND ON ATTRACTING QUALIFIED EMPLOYEES FOR OUR
FUTURE SUCCESS


Our success depends to a significant degree upon the continued contributions of
our senior management and key technical personnel, any of whom would be
difficult to replace. The loss of these individuals could materially adversely
affect our operations. We believe our future success will also depend on our
ability to attract and retain additional highly skilled managerial, product
development, marketing, sales, customer support and operations personnel to
support our growing business. Competition for these personnel is intense,
especially for engineers and especially in the San Francisco Bay Area where we
maintain our headquarters. We cannot be certain that we will be successful in
recruiting and retaining such personnel. Our failure to do so could materially
adversely affect our business, financial condition and results of operations.


                                       24


OUR INTERNATIONAL BUSINESS ACTIVITIES SUBJECT US TO RISKS THAT COULD ADVERSELY
AFFECT OUR BUSINESS


During the three and six month period ended July 31, 1999 and the fiscal year
ended January 31, 1999, we derived approximately 33%, 36% and 32%, respectively,
of our total revenue from sales outside of North America. We expect that
international sales will continue to generate a significant percentage of our
total revenue in the foreseeable future and we also expect to continue to make
investments to further expand our international operations and to increase our
direct sales force in Europe and Asia.


Risks inherent in international operations include:

- -   The imposition of governmental controls and regulatory requirements
- -   The costs and risks of localizing products for foreign countries
- -   Unexpected changes in tariffs, import and export restrictions and other
    barriers and restrictions
- -   Greater difficulty in accounts receivable collection
- -   The restrictions of repatriation of earnings
- -   The burdens of complying with a variety of foreign laws
- -   Difficulties in staffing and managing foreign subsidiaries and branch
    operations


In addition, sales by Wind River's foreign subsidiaries are denominated in the
local currency, and an increase in the relative value of the dollar against such
currencies would reduce our revenues in dollar terms or make our products more
expensive and, therefore, potentially less competitive in foreign markets. Gains
and losses on the conversion to dollars of accounts receivable, accounts payable
and other monetary assets and liabilities arising from international operations
may contribute to fluctuations in our results of operations. Although we enter
into forward contracts to hedge the short-term impact of foreign currency
fluctuations, foreign currency fluctuations could materially adversely affect
Wind River's business, financial condition and results of operations.


We rely on distributors for sales of our products in certain foreign countries.
Accordingly, we are dependent on their ability to promote and support our
products and, in some cases, to translate them into foreign languages. Wind
River's international distributors generally offer products of several different
companies, including in some cases products that are competitive with Wind
River's products. We cannot predict that our international distributors will
continue to market our products or provide them with adequate levels of support.
Any changes in the relationships we have with our international distributors may
have a material adverse effect on our business, financial condition and results
of operations.


OUR INABILITY TO PROTECT OUR INTELLECTUAL PROPERTY WOULD IMPAIR OUR COMPETITIVE
POSITION


We believe that our continued success depends primarily upon continuing
innovation, marketing, and technical expertise, as well as the quality of
product support and customer relations. At the same time, our success is
partially dependent upon the proprietary technology contained in our products.
We currently rely on a combination of patents, copyrights, trademarks, trade
secret laws, and contractual provisions to establish and protect our
intellectual property rights in our products. We cannot be certain that the
steps we take to protect our intellectual property will adequately protect our
rights, that others will not independently develop or otherwise acquire
equivalent or superior technology, or that we can maintain such technology as
trade secrets. End user licenses of our software are frequently in the form of
shrink wrap or click wrap license agreements, which are not signed by licensees,
and these may be


                                       25


unenforceable in some cases. Policing unauthorized use of our products is
difficult, and while we are unable to determine the extent to which software
piracy of our products exists, software piracy can be expected to be a
persistent problem. In addition, employees, consultants, and others who
participate in the development of our products may breach their agreements
with us regarding our intellectual property, and we may not have adequate
remedies for any such breach. Finally, the laws of some of the countries in
which our products are or may be developed, manufactured or sold may not
protect our products and intellectual property rights to the same extent as
the laws of the United States or at all. We may initiate claims or litigation
against third parties for infringement of our proprietary rights or to
establish the validity of our proprietary rights. Litigation to determine the
validity of any claims, whether or not such litigation is determined in our
favor, could result in significant expense to us and divert the efforts of
our technical and management personnel from productive tasks. Our failure to
protect our intellectual property rights could have a material adverse effect
on our business, and financial condition and results of operations.


THIRD PARTY CLAIMS OF PATENT INFRINGEMENT COULD RESULT IN SUBSTANTIAL COST


We occasionally receive communications from third parties alleging patent
infringement, and there is always the chance that third parties may assert
infringement claims against us. Any such claims, with or without merit, could
result in costly litigation, expense of significant resources to develop
non-infringing technology, cause product shipment delays or require us to enter
into royalty or licensing agreements. We cannot be certain that the necessary
licenses will be available or that they can be obtained on commercially
reasonable terms. If we were to fail to obtain such royalty or licensing
agreements in a timely manner and on reasonable terms, our business, financial
condition and results of operations would be materially adversely affected. We
believe that our products and technology do not infringe on the intellectual
property rights of others or upon intellectual property rights that may be
granted in the future pursuant to pending applications. We also believe that we
will not be required to obtain licenses of technology owned by other parties.


DEFECTS IN OUR PRODUCTS COULD ADVERSELY AFFECT OUR OPERATING RESULTS AND EXPOSE
WIND RIVER TO SIGNIFICANT PRODUCT LIABILITY CLAIMS


Because of their complexity, software products, including Wind River's, have in
the past and may in the future contain undetected or unresolved errors,
particularly when first introduced or as new versions are released. Despite
extensive testing, errors may be found in our current or future products or
enhancements after commencement of commercial shipments. If this occurs, we may
experience delay in or loss of market acceptance and sales, product returns,
diversion of development resources, injury to our reputation, and increased
service and warranty costs, any of which could materially adversely affect our
business, financial condition and results of operations.


Our products are increasingly used in applications, such as network
infrastructure, transportation, medical and mission-critical business systems,
in which the failure of the embedded system could cause property damage,
personal injury or economic loss resulting in product liability claims against
us. Although our agreements with our customers typically contain provisions
intended to limit our exposure to liability claims, these provisions may not be
effective in doing so in all circumstances or in all jurisdictions. We maintain
product liability insurance covering certain damages arising from use of our
products, however such insurance may not adequately cover claims brought against
us. Liability claims against us could require us to spend significant time and
money in litigation and, if successful, to pay significant damages. As a result,
such claims could damage our reputation and materially adversely affect our
business, financial condition and results of operations.


                                       26


WE HAVE SUBSTANTIAL DEBT SERVICE AND PRINCIPAL REPAYMENT OBLIGATIONS, WHICH
COULD MAKE IT DIFFICULT FOR US TO OBTAIN FINANCING


We sold $140 million of 5% convertible subordinated notes in 1997, which mature
in 2002. This debt financing increased significantly both the ratio of our
long-term debt to our total capitalization and our interest expenses. The degree
to which we are leveraged could materially adversely affect our ability to
obtain financing for working capital or acquisitions, should we need to do so.
The notes are convertible into our common stock at a price of $32.33 per share,
and no notes have been converted to date. On August 1, 2002, we will be required
either to pay off or refinance any unconverted notes. We do not know if we will
be able to refinance the notes on favorable terms or at all. If a significant
amount of the notes remains unconverted at maturity and we are unable to
refinance the notes, the repayment would deplete our cash reserves
significantly.


THE YEAR 2000 PROBLEM MAY ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION
AND RESULTS OF OPERATIONS


The "year 2000 problem" is typically the result of limitations of certain
software written using two digits rather than four digits to define the
applicable year resulting in certain programs recognizing "00" as the year 1900
rather than the year 2000. If systems do not currently recognize date
information when the year changes to 2000, there could be an adverse impact on
our operations. The risk exists primarily in four areas:


- -    Potential warranty or other claims from our customers, which may result in
     significant expense to Wind River
- -    Failure of systems we use to run our business, which could disrupt our
     business operations
- -    Failure of systems used by our suppliers, which could delay or affect the
     quality of our manufacturing or products
- -    The potential failure of our products due to Year 2000 problems, which may
     require that we replace any such products and potentially incur significant
     unexpected expenses


Although we believe our most current releases of our products, including third
party software integrated into certain products are year 2000 compliant, because
all customer situations cannot be anticipated, we may see an increase in
warranty and other claims as a result of the year 2000 transition. In addition,
litigation regarding year 2000 compliance issues may increase. Significant
customer claims or litigation, even if decided in our favor, could have a
material adverse impact on our business, financial condition, or results of
operations.


The majority of our products are combined by our customers with other software
programs or hardware devices not provided by us. These combinations with other
products that are not year 2000 compliant or modifications of our products by
our customers may introduce year 2000 issues for our customers. Our customers'
inability to remedy their own year 2000 problems could affect their demand for
our products which could materially and adversely affect our business, financial
condition and results of operations.


                                       27


OUR STOCK PRICE HAS BEEN AND MAY CONTINUE TO BE VOLATILE


The trading price of our common stock has been and is likely to be volatile. It
could fluctuate widely in response to a variety of factors, including:


- -   actual or anticipated variations in our operating results
- -   announcements of new products or significant events or transactions by us
    or our competitors
- -   changes in our industry
- -   changes in financial estimates by securities analysts
- -   pricing pressures
- -   general market conditions
- -   events affecting other companies that investors believe to be comparable to
    us
- -   other events or factors that may be beyond our control


In recent years, the stock markets in general and the shares of technology
companies in particular have experienced extreme price fluctuations. These
fluctuations often have been unrelated or disproportionate to the operating
performance of the companies affected. Any change in investors' perception of
our prospects could depress our stock price regardless of our results. Other
broad market and industry factors may decrease our stock price, as may general
political or economic conditions such as recessions or interest rate or currency
fluctuations. In the past, following declines in the market price of a company's
securities, securities class action litigation often has been instituted against
the company. Litigation of this type, even if ultimately unsuccessful, could
result in substantial costs and a diversion of management's time and focus,
which could materially affect our business, financial condition and results of
operations.


                                       28


Item 3.  Quantitative and Qualitative Disclosures about Market Risk


INTEREST RATE SENSITIVITY

Wind River's exposure to market risk for changes in interest rates relate
primarily to its investment portfolio and long-term debt obligations.


Wind River places its investments with high quality credit issuers and, by
policy, limits the amount of credit exposure to any one issuer. As stated in its
policy, Wind River's first priority is to reduce the risk of principal loss.
Consequently, Wind River seeks to preserve its invested funds by limiting
default risk, market risk and reinvestment risk. Wind River mitigates default
risk by investing in only high quality credit securities that it believes to be
low risk and by positioning its portfolio to respond appropriately to a
significant reduction in a credit rating of any investment issuer or guarantor.
The portfolio includes only marketable securities with active secondary or
resale markets to ensure portfolio liquidity.


Wind River believes an immediate 100 basis point move in interest rates
affecting Wind River's floating and fixed rate financial instruments as of July
31, 1999 would have an immaterial effect on Wind River's pretax earnings. Wind
River also believes the immediate 100 basis point move in interest rates would
have an immaterial effect on the fair value of Wind River's financial
instruments.


FOREIGN CURRENCY RISK

Wind River transacts business in various foreign currencies, primarily in
Japanese yen and certain European currencies. Wind River has established a
foreign currency hedging program, utilizing foreign currency exchange contracts
for its foreign currency transaction exposures in Japan and certain European
countries. Under this program, increases or decreases in Wind River's foreign
currency transactions are partially offset by gains and loses on the forward
contracts, so as to mitigate the possibility of foreign currency transaction
gains and losses. Wind River does not use forward contracts for trading
purposes. All outstanding forward contracts at the end of a period are
marked-to-market with unrealized gains and losses included in other income, net,
and thus are recognized in income in advance of the actual foreign currency cash
flows. As these forward contracts mature, the realized gains and losses are
recorded and are included in net income as a component of other income, net.
Wind River's ultimate realized gain or loss with respect to currency
fluctuations will depend on the currency exchange rates and other factors in
effect as the contracts mature. The unrealized gains and losses on the
outstanding forward contracts at July 31, 1999 were immaterial to Wind River's
consolidated financial statements. Due to the short-term nature of the forward
contracts, the fair value at July 31, 1999 was negligible. The realized gains
and losses on these contracts as they matured were not material to the
consolidated operations of Wind River.


INTEREST RATE SWAP RISK

Wind River entered into a 5.9% accreting interest rate swap to reduce the impact
of changes in interest rates on its floating interest rate operating lease for
its new headquarters. At July 31, 1999, the notional amount of the accreting
interest rate swap was $28.5 million. The estimated fair value at July 31, 1999
was negligible.


                                       29


EQUITY PRICE RISK

Wind River owns 633,752 shares of common stock of e-SIM Ltd., formerly known
as Emultek, Inc., an Israeli corporation. Wind River purchased the common
stock prior to e-SIM's public offering price of $7.50 per share. e-SIM went
public in July 1998, and at July 31, 1999, the closing price of e-SIM's stock
was $11.13 per share. Wind River also owns 208,333 shares of common stock of
Liberate Technologies, Inc, a Delaware corporation. Wind River purchased the
stock prior to Liberate's public offering price of $16.00 per share. Liberate
went public in July 1999, and at July 31, 1999, the closing price of
Liberate's stock was $19.13 per share. Wind River values these investments
using the closing price of the stock at the end of each month. As a result,
Wind River reflects these investment on its balance sheet at July 31, 1999 at
their market value of approximately $11.0 million in aggregate, with the
unrealized gains and losses excluded from earnings and reported in
accumulated other comprehensive income or loss component of stockholders'
equity.

                           PART II - OTHER INFORMATION

ITEM 2.           CHANGES IN SECURITIES AND USE OF PROCEEDS


                  On June 30, 1999, Wind River sold 100,000 shares of
                  unregistered common stock to William B. Elmore, a director of
                  the Company, for a purchase price of $16.50 per share, the
                  fair market value of the common stock on such date. The
                  transaction was exempt from registration under the Securities
                  Act of 1933, as amended, under Section 4(2) thereof, as a
                  transaction not involving a public offering.


                  On June 30, 1999, Wind River issued an aggregate of 720,923
                  shares of unregistered common stock to the shareholders of
                  RouterWare, Inc. in exchange for all the outstanding common
                  stock of RouterWare. As a result, RouterWare is now a wholly
                  owned subsidiary of Wind River. The transaction was exempt
                  from registration under the Securities Act of 1933, as
                  amended, under Section 4(2) thereof, as a transaction not
                  involving a public offering.


ITEM 4.           SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS


                  The Company's Annual Meeting of Stockholders was held on June
                  24, 1999 in Alameda, California. Of the 40,492,666 shares
                  outstanding as of the record date, 33,614,716 were present or
                  represented by proxy at the meeting. The results of the voting
