ITEM 1.


BUSINESS

Wind River Systems, Inc. ("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. Some examples of embedded computers are 
telecommunications products such as PBXs, routers, central office switches, 
and call processing systems; office products such as fax machines, laser 
printers, and photocopiers; vehicle anti-lock brakes and navigation systems; 
consumer products such as digital cameras, camcorders, video games, and 
set-top boxes; medical instrumentation and imaging systems; industrial 
automation equipment such as robots and process control equipment; and 
aerospace products used for projects such as NASA's on-going missions to 
Mars.  Wind River's flagship product, TORNADO-TM-, enables customers to 
enhance product performance, standardize designs across projects, reduce 
research and development costs, and shorten product development cycles.

Wind River markets its products and services in North America and Europe 
primarily through its own direct sales organization, which consists of 
salespersons and field engineers. Wind River has eighteen licensed 
international distributors principally to serve customers in regions not 
serviced by its direct sales force or its Japanese master distributors. Wind 
River's customers include Boeing Company, Cisco Systems, Inc., Ericsson Radio 
Systems AB, General Motors Corporation, Hewlett-Packard Company, Hitachi, 
Ltd., Hughes Aircraft Company, Lucent Technologies Inc., Intel Corporation, 
Lockheed-Martin Corporation, McDonnell Douglas Corporation, Mitsubishi 
Electric Corporation, Motorola, Inc., Network Computer, Inc., Nippon Electric 
Corporation, Northern Telecom Ltd., Raytheon Company, Siemens AG, Sun 
Microsystems, Inc., and TRW Inc.

Wind River is an ISO 9001 certified company.  Wind River was incorporated in 
California in February 1983 and reincorporated in Delaware in April 1993. Its 
principal executive offices are located at 500 Wind River Way, Alameda, 
California 94501, and its telephone number at that location is (510) 748-4100.

BACKGROUND

Embedded systems consist of a microprocessor and related software 
incorporated into a larger device, dedicated to performing a specific set of 
tasks. Embedded systems provide an immediate, predictable response to an 
unpredictable sequence of external events. As more powerful microprocessors 
have become available and have decreased in price, embedded systems are being 
used in a wider range of applications and digital appliances and are 
facilitating the development of entirely new products. In addition, emerging 
Embedded Internet-Registered Trademark- applications for interactive 
entertainment, network computers, remote maintenance, and other areas may 
offer significant additional opportunities for embedded systems.

                                          3
<PAGE>

To succeed in today's increasingly competitive markets, manufacturers using 
embedded computers must bring complex applications for embedded systems to 
market rapidly and economically. Developing real-time embedded software 
applications has evolved from a relatively modest programming task to a 
complex engineering effort. As more powerful and affordable 32-bit 
microprocessors have become available, products based on them have become 
richer in features and functions. In addition, the complexity of embedded 
software is increasing dramatically, while the time available for product 
development is decreasing. More sophisticated development tools are required 
to develop these more complex applications, frequently including a real-time 
operating system ("RTOS") that provides developers far more features, higher 
performance and greater productivity than that necessary or feasible for 
programming prior generations of microprocessors. Wind River's flexible 
operating systems and powerful development tools allow customers to create 
and standardize complex real-time embedded software applications quickly and 
efficiently.

As real-time embedded applications increase in complexity, the costs 
associated with providing software development, support and training of 
engineers are rising rapidly. In addition, time-to-market, conformance to 
standards, and product reliability have become critical issues for companies 
developing real-time embedded applications.

PRODUCTS

Wind River's operating systems and development tools allow customers to 
create complex real-time embedded software applications more quickly, more 
economically and with less risk than creating such applications using 
internally developed systems and tools. Wind River typically charges a 
one-time fee for a development license and a run-time license fee for each 
copy of its operating system embedded in the customer's product. A key 
component of Wind River's strategy is to significantly increase revenue 
through run-time license fees. Any increase in the percentage of revenues 
attributable to run-time licenses will depend on Wind River's successful 
negotiation of run-time license agreements and on the successful 
commercialization by its customers of the underlying products.

TORNADO

TORNADO is a development environment for embedded applications and is 
available for UNIX, Windows NT, Windows 95, and Windows 98 development 
platforms. TORNADO was introduced in September 1995 and subsequently won the 
Electronic Design News award for Innovation of the Year. In November 1998, 
Wind River introduced TORNADO II.  TORNADO II provides significant technical 
advances for accelerated productivity, advanced networking connectivity, and 
a platform for HTML, Java, and C++ graphics development.  

TORNADO is a scalable cross-development environment that enables engineers to 
develop embedded applications on a host workstation or PC and download the 
code via a network or other communications channel to an RTOS that runs on 
all significant 32- and 64- bit embedded target microprocessors.

TORNADO consists of three integrated components: the TORNADO toolset, a set 
of cross-development tools and utilities; the VXWORKS-Registered 
Trademark-run-time system, a high performance, scalable RTOS that executes on 
the target processor; and a full range of communications options for the 
target connection to the host.

The TORNADO development toolset consists of a launcher, a GNU compiler for C 
and C++ programs, a remote source level debugger, a user-interface shell, a 
browser, and a variety of other software tools that run on the development 
host. TORNADO also offers a completely open and extensible environment that 
facilitates the integration of a wide variety of third-party tools as well as 
the customization of TORNADO tools by the developer.

A set of application program interfaces ("APIs") is available and published 
on the Internet for reference, from the graphical user interface ("GUI") to 
the connection implementation. Wind River believes that this open environment 
may make TORNADO the development foundation of choice for embedded and 
real-time applications.

                                          4
<PAGE>

VXWORKS-Registered Trademark- is a high-performance, scalable RTOS based on 
an object-oriented microkernel architecture that can form the foundation for 
memory-constrained applications as small as 20 kilobytes or support large, 
complex applications. The run-time system offers over 1,100 utility routines 
such as buffer and list management for accelerating application development. 
VXWORKS provides broad portability over a wide variety of commercial 
processors and custom target hardware boards and adheres to a variety of 
computing standards, including POSIX 1003.1/1b, ANSI C, and TCP/IP.

For communications between the development platform and the embedded target, 
TORNADO provides a variety of options, including Ethernet, serial line, 
in-circuit emulator, ROM emulator, or custom backend.  TORNADO eliminates 
many of the dependencies of a traditional cross-development environment. With 
TORNADO, developers can use any host-target communications and the 
capabilities of the toolset remain the same regardless of target processor 
resources.

GRAPHICS PORTFOLIO

Wind River's comprehensive portfolio of graphics solutions makes it possible 
to incorporate graphical user interfaces and to render, or display, rich 
graphical content on traditional embedded devices and leading-edge 
information appliances. Examples of products employing Wind River's graphics 
solutions include process visualization terminals, front panels for digital 
imaging devices, instrumentation and medical equipment, point-of-sale 
terminals and information kiosks, as well as graphics and Internet-centric 
devices such as screen phones, television set-top boxes, and car navigation 
systems.  The graphics portfolio addresses the diverse graphics requirements 
of embedded computers with four core, standards-based solutions: PERSONAL 
JWORKS-TM- (Wind River's port of Sun Microsystems' PersonalJava 
specification), Wind River's version of NCI's eNavigator-TM- (ENAVIGATOR), 
HTMLWORKS-TM-, and ZINC-Registered Trademark- FOR VXWORKS.

TORNADO FOR INTELLIGENT I/O 

A consortium of leading enterprise computing vendors has proposed an 
architecture, known as an I2O, to define and promote an open, standard set of 
interface specifications for high-performance I/O subsystems.  These 
specifications will be used to simplify the task of building and maintaining 
those subsystems for interface cards and PC server platforms.  The I2O 
specification makes it possible for systems to distribute I/O functions 
across multiple processors, dramatically improving I/O and overall system 
performance.  Additionally, the specification allows vendors of network and 
peripheral interface cards to write a single device driver that will be 
compatible with a comprehensive range of operating systems, OS releases, and 
vendor OS implementations. Wind River has entered into agreements with Intel 
Corporation, certain division of Digital Equipment Corporation (now part of 
Intel) and Symbios Logic, Inc. (now part of LSI Logic), under which such 
companies will bundle Wind River's IXWORKS-Registered Trademark- operating 
system into their respective input/output platforms ("IOPs").  IxWorks, Wind 
River's I2O real-time operating system ("IRTOS") based on VXWORKS, is a 
component of Wind River's TORNADO FOR INTELLIGENT I/O products and 
facilitates the development of I2O-capable products by ensuring ongoing I2O 
compliance.  It also permits companies to get their products to market faster 
by offering immediate availability of the IRTOS, the most significant 
software building block of an I2O-ready system. A license for IXWORKS may be 
included with IOPs shipped.  This arrangement permits manufacturers to 
develop their products quickly, since IXWORKS is available immediately.  Wind 
River believes that its relationships with Intel and LSI Logic for the 
implementation of the I2O specification may open up a new market opportunity 
for its products. 

EMBEDDED INTERNET MARKET INITIATIVE

Wind River's TORNADO FOR EMBEDDED INTERNET-Registered Trademark- product 
suite is a fully integrated package for bringing the advantages of the 
Internet to embedded computers such as smart phones, TV set-top boxes, 
network computers, networked printers, cable modems, and switches. With the 
introduction of TORNADO FOR EMBEDDED INTERNET components, Wind River has 
provided a common technology to build and deploy products throughout the 
Internet, including its infrastructure, servers, and smart appliances.  Wind 
River believes there may be opportunities to increase the market size and 
scope for its products, which incorporate, for example, server technology for 
posting information to the Internet or corporate intranets, browsers for 
viewing information on the World Wide Web, and "Java compliant" products for 
developing "write once, run anywhere" applications.  Wind River's EMBEDDED 
INTERNET product suite includes PERSONAL JWORKS (based on Sun Microsystems' 
PersonalJava specification), and WIND WEB SERVER.

annual fee basis. Wind River's TORNADO includes a tool for submitting problem 
reports and receiving responses via the Internet.

ENGINEERING SERVICES. A number of services are provided on a fee-for-service 
basis, including BSP validation, application-level consulting, customization, 
and porting to strategic semiconductor architectures. These are coordinated 
and performed by the Engineering Services Group in North America and Japan, 
though they may on occasion be supported by the Engineering Group or outside 
subcontractors in North America and Europe.

CONSULTING SERVICES.  Wind River offers consulting services to develop 
applications for embedded devices.  When developers of software content 
require outside development expertise, Wind River's consulting professionals 
help these developers by assisting or performing their software development.  
Wind River offers consulting services in areas such as BSP and device driver 
development, networking and graphics.

STRATEGIC ALLIANCES

Wind River believes that strategic relationships with semiconductor 
manufacturers and embedded device manufacturers are significant strengths 
that are key to its future success in the embedded systems marketplace. Wind 
River has strategic relationships with most of the major semiconductor 
companies including Advanced RISC Machines Limited, Fujitsu Limited, Hitachi, 
Ltd, Intel Corporation, MIPS Technologies, Inc., Mitsubishi Electric 
Corporation, Motorola, Inc., NEC Corporation, ST Microelectronics, Siemens AG 
and Sun Microsystems, Inc.  Wind River has ported its VxWorks technology to 
their semiconductors, allowing Wind River to leverage its partners' sales 
channels to give its products broad market exposure. Wind River also enters 
into joint marketing and sales agreements with certain developers of 
third-party applications as a means to enhance its products with 
industry-specific features. In addition, Intel and Wind River have a 
strategic relationship pursuant to which Intel supplies an evaluation copy of 
TORNADO FOR INTELLIGENT I/O to each customer purchasing an Intel i960Rx I/O 
microprocessor and a license for IXWORKS for each such microprocessor sold. 
Wind River also has developed strategic relationships with Network Computer, 
Inc. and Sun Microsystems for Embedded Internet applications ranging from 
network computers to hand-held and intelligent phones.

CUSTOMERS

Wind River's products have been deployed by a broad range of organizations, 
including companies in the following industries: global communications (both 
data and voice), digital imaging, consumer electronics, computers and 
peripherals, medical instrumentation, defense electronics and aerospace, 
research, automotive control, and industrial measurement and control. No 
single customer accounted for more than 10% of Wind River's total revenues in 
fiscal 1999.

MARKETING, SALES AND DISTRIBUTION

In North America and Europe, Wind River markets its products and services 
primarily through its own direct sales organization, which consists of 
salespersons and field application engineers. Wind River's sales force 
presents Wind River and its products for licensing to prospective customers, 
while application engineers provide technical pre-sale and post-sales 
support.  As part of the sales cycle, Wind River's direct sales force 
generally provides technical presentations, product demonstrations and, often 
an on-site customer evaluation of Wind River software.  As of January 31, 
1999, Wind River had 111 domestic direct salespersons and field application 
engineers located throughout North America, 40 direct salespersons and field 
application engineers throughout Europe and 10 sales and marketing employees 
in Japan.

Wind River distributes its products in Japan through Wind River Systems, 
K.K.("WRSKK"), a subsidiary in which it owns a 70% equity interest. Innotech 
Corporation, Kobe Steel Ltd. and Nissin Electric Ltd., each owns a 10% equity 
interest. Wind River has licensed its products exclusively to WRSKK for 
distribution in Japan. WRSKK has in turn entered into master distributor 
agreements with its three joint venture partners that provide the right to 
appoint sub-distributors. See Note 13 of Notes to Consolidated Financial 
Statements.

Wind River has licensed eighteen international distributors, principally to 
serve customers in regions not serviced by Wind River's direct sales force or 
its Japanese master distributors. Wind River also has established strategic 
relationships with computer, semiconductor and software vendors and works 
closely with a number of system integrators worldwide that enable Wind River 
to further broaden the geographic and market scope for its products.

                                          8
<PAGE>

Revenues from international sales represented $41.6 million, $26.9 million, 
and $22.1 million or approximately 32%, 29% and 34% of total revenue in 
fiscal 1999, 1998 and 1997, respectively. See Note 14 of Notes to 
Consolidated Financial Statements for a summary of operations by geographic 
region, and "- Additional Risk Factors - Risks Associated with International 
Operations." Prices for international customers are quoted from a local 
currency international price list.  The price list is prepared based on the 
U.S. dollar price list but reflects the higher cost of doing business outside 
the United States.  International customers are invoiced in the local 
currency or U.S. dollars using current exchange rates.  

Wind River has experienced, and expects to continue to experience, 
significant seasonality resulting primarily from customer buying patterns and 
product development cycles. Wind River has generally experienced the 
strongest demand for its products in the fourth quarter of each fiscal year 
and the weakest demand in the first quarter of each fiscal year. Quarterly 
revenue levels have increased over the levels for like quarters in the prior 
fiscal years but have typically decreased in the first quarter of each fiscal 
year from the fourth quarter of the prior fiscal year.

COMPETITION

The embedded real-time software industry is highly competitive and is 
characterized by rapidly advancing technology.  Therefore, Wind River's 
ability to obtain such business is dependent upon its ability to offer better 
strategic concepts and technical solutions, time-to-market for our customers, 
competitive prices, integration into certain capabilities like graphic 
interfaces, communication protocols and peripheral controllers, customer 
support response time, or a combination of these factors.  There can be no 
assurance that Wind River will be able to effectively compete in each of 
these areas, and any failure to compete in the embedded real-time software 
market would have a material adverse effect on Wind River's business, 
financial condition and results of operations.  In order to maintain or 
improve its position in the industry, Wind River must continue to enhance its 
current products and rapidly develop new products and product extensions. 
Wind River believes that its principal competition comes from companies that 
develop real-time embedded software development systems in-house rather than 
purchase such systems from independent software vendors such as Wind River, 
and that it is thus subject to the customers' "develop versus buy" decisions 
in addition to the factors set forth above. Many of these organizations have 
substantial internal programming resources with the capability to develop 
specific products for their needs. Wind River also competes with other 
independent software vendors, including Integrated Systems, Inc., Mentor 
Graphics, Inc. (through its acquisition of Microtec/Ready Systems), Microware 
Systems Corporation, QNX Software Systems, Ltd., Accelerated Technology, Inc. 
and Microsoft Corporation.  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 Wind River's 
products.  Many of Wind River's existing and potential competitors have 
substantially greater financial, technical, marketing and sales resources 
than Wind River. 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. Furthermore, current and potential competitors have established or 
may establish cooperative relationships among themselves or with third 
parties. Accordingly, it is possible that new competitors or alliances among 
competitors may emerge and rapidly acquire significant market share. In 
addition, Wind River is aware of ongoing efforts by competitors to emulate 
the performance and features of Wind River's products, and there can be no 
assurance that competitors will not develop equivalent or superior technology 
to that of Wind River. Because substantially all of Wind River's revenues 
have been derived from sales of the Tornado, VxWorks and IxWorks family of 
products and services, the effects of competition could be more adverse than 
would be the case if Wind River had a broader product offering. In addition, 
competitive pressures could cause Wind River to reduce the prices of its 
products and services, which would result in reduced profit margins. There 
can be no assurance that Wind River will be able to compete effectively 
against its current and future competitors. If Wind River is unable to 
compete successfully, its business, financial condition and results of 
operations would be materially and adversely affected.

PRODUCT DEVELOPMENT AND ENGINEERING

Wind River believes that its success will depend primarily on its ability to 
maintain and enhance its current product line, develop new products, maintain 
technological competitiveness and meet an ever-expanding range of customer 
and market requirements. Wind River's product development and engineering 
group, at January 31, 1999, includes 181 full-time 

                                          9
<PAGE>

employees. During fiscal 1999, 1998 and 1997, product development and 
engineering expenses were $17.6 million, $12.0 million and $7.7 million, 
respectively, excluding capitalized software development costs. In fiscal 
year 1999, Wind River did not capitalize costs for software development.  In 
fiscal years 1998 and 1997, costs capitalized for software development were 
$803,000 and $707,000, respectively.  See "Notes to Consolidated Financial 
Statements" for a more complete description of Wind River's capitalization of 
certain software development costs. Wind River anticipates that it will 
continue to commit substantial resources to research and product development 
in the future. 

The embedded real-time software industry faces a fragmented market 
characterized by ongoing technological developments, evolving industry 
standards and rapid changes in customer requirements. The introduction of 
products embodying new technologies and the emergence of new industry 
standards could render Wind River's existing products obsolete and 
unmarketable. Wind River's success depends and will continue to depend upon 
its ability to continue to develop and introduce in a timely manner new 
products, including new releases, applications and enhancements, that take 
advantage of technological advances, to identify and adhere to emerging 
standards, to continue to improve the functionality of its Tornado 
development environment and the scalability and functionality of the VxWorks 
operating system, to offer its products across a spectrum of microprocessor 
families used in the embedded systems market and update its products in a 
systematic manner such that they remain compatible with the microprocessor 
families and to respond promptly to customers' requirements. The inability to 
develop and introduce new products or product enhancements in a timely manner, 
due to resource constraints or technological or other reasons, could have a 
material adverse effect on Wind River's business, financial condition or 
results of operations.

From time to time, Wind River or its competitors may announce new products, 
capabilities or technologies that have the potential to replace or shorten 
the life cycles of Wind River's existing products. There can be no assurance 
that announcements of currently planned or other new products by Wind River 
or others will not cause customers to defer purchasing existing Wind River 
products. Any failure by Wind River to anticipate or respond adequately to 
changing market conditions, or any significant delays in product development 
or introduction, would have a material adverse effect on Wind River's 
business, financial condition and results of operations.  See "Additional 
Risk Factors - Product Development."

Wind River is continuously engaged in product development for new or changing 
markets.  In particular, Wind River has invested significant time and effort, 
together with a consortium of industry participants, in the development of 
I(2)O, a new specification that is intended to create an open standard set of 
interface specifications for high performance I/O systems. The specification 
is intended to be used by system, network and peripheral interface card and 
operating systems vendors to simplify the task of building and maintaining 
high-performance I/O subsystems. Wind River also has developed IxWorks, a 
real-time operating system for use in conjunction with the I(2)O specification. 
The success of the I(2)O specification and the IxWorks product line depends 
heavily on its adoption by a broad segment of the industry. Wind River also 
has expended, and continues to expend, substantial time and financial 
resources to develop embedded operating software and development tools for 
Internet applications. 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 is an increasing 
number of new Internet protocols to which Wind River's products must be 
ported. It is unclear which of these competing protocols ultimately will 
achieve market acceptance. If the protocols upon which Wind River's Internet 
products are based ultimately fail to be widely adopted, Wind River's 
business, financial condition and results of operations may be materially and 
adversely affected. It is difficult to predict with any assurance whether 
demand for any of these products will develop or increase in the future. If 
these markets, or any other new market targeted by Wind River in the future, 
fail to develop, develop more slowly than anticipated or become saturated 
with competitors, if Wind River's products are not developed in a timely 
manner, or if Wind River's products and services do not achieve or sustain 
market acceptance, Wind River's business, financial condition and results of 
operations would be materially and adversely affected.  

Like all software products, Wind River's products may contain undetected 
errors that could cause loss or delay in market acceptance or cause failures 
in the products containing the embedded systems.  Damages and injury from 
such failures could result in product liability claims against Wind River.  
See "Additional Risk  Factors - Risks of Product Defects; Product and Other 
Liability."

PROPRIETARY RIGHTS

Wind River's success is heavily dependent upon its proprietary technology. To 
protect its proprietary rights, Wind River relies on a combination of 
copyright, trade secret, patent and trademark laws, nondisclosure and other 
contractual restrictions on copying, distribution and technical measures. 
Wind River seeks to protect its software, documentation and other written 
materials through trade secret and copyright laws, which provide only limited 
protection. In addition, Wind River has one registered U.S. patent.  There 
can be no assurance that the claims allowed will be of sufficient scope or 
strength (or be issued in all countries where Wind River's products can be 
sold) to provide meaningful protection or any commercial advantage to Wind 
River. As a part of its confidentiality procedures, Wind River generally 
enters into nondisclosure agreements with its employees, consultants, 
distributors and corporate partners and limits access to and distribution of 
its software, documentation and other proprietary information. End user 
licenses of Wind River's software are frequently in the form of shrink wrap 
license agreements, which are not signed by licensees, and therefore may be 
unenforceable under the laws of many jurisdictions. Despite Wind River's 
efforts to protect its proprietary rights, it may be possible for 
unauthorized third parties to copy Wind River's products or to reverse 
engineer or obtain and use information that Wind River regards as 
proprietary. There can be no assurance that Wind River's competitors will not 
independently develop technologies that are substantially equivalent or 
superior to Wind River's technologies. Policing unauthorized use of Wind 
River's products is difficult, and while Wind River is unable to determine 
the extent to which software piracy of its products exists, software piracy 
can be expected to be a persistent problem. In addition, effective protection 
of intellectual property rights may be unavailable or limited in certain 
countries. The status of U.S. patent protection in the software industry is 
not well defined and is likely to evolve as the U.S. Patent and Trademark 
Office grants additional patents. Patents have been granted on fundamental 
technologies in software, and patents may issue in the future that relate to 
fundamental technologies incorporated into Wind River's products.

As the number of patents, copyrights, trademarks, trade secrets and other 
intellectual property rights in Wind River's industry increases, products 
based on Wind River's technology may increasingly become the subject of 
infringement claims.  Wind River has received in the past and may receive in 
the future letters from third parties asserting infringement claims against 
Wind River. There can be no assurance that third parties will not assert 
infringement claims against Wind River in the future. Any such claims, 
whether with or without merit, could be time consuming, result in costly 
litigation, cause product shipment delays or require Wind River to enter into 
royalty or licensing agreements. Such royalty or licensing agreements, if 
required, may not be available on terms acceptable to Wind River, or at all, 
which could have a material adverse effect on Wind River's business, 
financial condition and results of operations. In the event of an adverse 
ruling in any such litigation, Wind River might be required to pay 
substantial damages, discontinue the use and sale of infringing products, 
expend significant resources to develop non-infringing technology or obtain 
licenses to infringing technology.  In addition, Wind River may initiate 
claims or litigation against third parties for infringement of Wind River's 
proprietary rights or to establish the validity of Wind River's proprietary 
rights. Litigation to determine the validity of any claims, whether or not 
such litigation is determined in favor of Wind River, could result in 
significant expense to Wind River and divert the efforts of Wind River's 
technical and management personnel from productive tasks. 

MANUFACTURING AND BACKLOG

Wind River's manufacturing operation consists of assembling, packaging and 
shipping the software products and documentation needed to fulfill each 
order. Limited manufacturing is currently performed in Wind River's Alameda, 
California facility. Outside vendors provide tape and CD duplication, 
printing of documentation and manufacturing of packaging materials.

Wind River does not believe that backlog is a meaningful indicator of sales 
that can be expected in future periods, particularly in view of the fast pace 
of technological change in the software industry. Wind River's order 
fulfillment process is intended to efficiently manage the flow of products to 
customers, often resulting in a number of weeks of backlog.  At January 31, 
1999, backlog was approximately 9 to 12 weeks of sales. Backlog includes 
orders that may be filled at various times throughout the fiscal year.

EMPLOYEES

Wind River had, at January 31, 1999, 598 employees, including 324 in sales, 
marketing and support activities, 181 in product development and engineering 
and 93 in management, operations, finance and administration. Of these 
employees, 441 were located in North America and 157 were located outside of 
North America. None of Wind River's employees is represented by a labor union 
or is subject to a collective bargaining agreement. Wind River has never 
experienced a work stoppage. See "-Additional Risk Factors - Management of 
Growth; Dependence on Key Personnel; Need for Additional Personnel."

ADDITIONAL RISK FACTORS

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.

FLUCTUATIONS IN OPERATING RESULTS  

Wind River has experienced from time to time significant period-to-period 
fluctuations in revenues and operating results and anticipates that such 
fluctuations will occur in the future. These fluctuations may be attributable 
to a number of factors, including the volume and timing of orders received 
during the quarter, the introduction, timing and acceptance of new products 
and product enhancements by Wind River or its competitors, unanticipated 
sales and buyouts of run-time licenses, stages of product life cycles, 
purchasing patterns of customers and distributors, market acceptance of 
products sold by Wind River's customers, competitive conditions in the 
industry, business cycles affecting the markets in which Wind River's 
products are sold, extraordinary events, such as acquisitions, including 
related charges, and economic conditions generally or in specific geographic 
areas. The future operating results of Wind River may fluctuate as a result 
of these and other factors, including Wind River's ability to continue to 
develop innovative and competitive products.  In addition, Wind River 
generally does not enter into long-term license agreements with its 
customers, and the timing of license fees is difficult to predict. The 
procurement process of Wind River's customers is often several months or 
longer from initial inquiry to order and may involve competing 
considerations. Further, as licensing of Wind River's products increasingly 
becomes a more strategic decision made at higher management levels, there can 
be no assurance that sales cycles for Wind River's product will not lengthen. 
Product revenue in any quarter depends primarily on the volume and timing of 
orders received in that quarter. Wind River has at times recognized a 
substantial portion of its total revenue from sales booked and shipped in the 
latter part of the quarter; thus, the magnitude of quarterly fluctuations may 
not become evident until late in a particular quarter. Because Wind River's 
staffing and operating expenses are based on anticipated total revenue 
levels, and a high percentage of Wind River's costs are fixed in the short 
term, small variations between anticipated orders and actual orders, as well 
as non-recurring or large orders, could cause disproportionate variations in 
Wind River's operating results from quarter to quarter. Revenues also are 
typically higher in the fourth quarter, which ends on January 31, than in 
other quarters of the fiscal year primarily as a result of purchases by 
customers prior to the calendar year end, as well as by customers who 
purchase at the commencement of a new calendar year. These trends are 
expected to continue.

Because the software industry is intensely competitive, software vendors have 
from time to time experienced price erosion of their products. As is typical 
in the software industry, Wind River's fixed costs as a percentage of 
revenues are high, and significant price erosion could have a material 
adverse effect on Wind River's revenues and operating results.  A number of 
additional factors may in the future cause Wind River's revenues and 
operating results to vary significantly from period to period. These factors 
include: software "bugs" or other product quality problems, including Year 
2000 compliance issues; changes in operating expenses; changes in company 
strategy; personnel changes; foreign currency exchange rates; and mix of 
products sold. Although Wind River has been profitable for the last several 
years on an annual basis, there can be no assurance that Wind River will be 
able to continue its growth in revenue or sustain its profitability on a 
quarterly or annual basis. Due to all of the foregoing factors, Wind River 
believes that period-to-period comparisons of its results of operations are 
not necessarily meaningful and should not be relied upon as an indication of 
future performance. It is possible that, in some future quarters, Wind 
River's operating results will be below the expectations of stock market 
analysts and investors. In such event, the market price of its common stock 
could decrease significantly.

                                          12
<PAGE>

RELIANCE ON CORE FAMILY OF PRODUCTS

Revenue from sales of the Tornado, VxWorks and IxWorks family of products and 
services accounted for substantially all of Wind River's revenues in each of 
the fiscal years ended January 31, 1999, 1998 and 1997. Wind River's future 
results depend heavily on continued market acceptance of these products in 
Wind River's current markets and successful application in new markets.  Any 
factor adversely affecting the market for the Tornado, VxWorks and IxWorks 
family of products and services could have a material adverse affect on Wind 
River's business, financial condition and results of operations. Wind River 
typically charges a one-time fee for a development license and a run-time 
license fee for each copy of Wind River's operating system embedded in the 
customer's products. A key component of Wind River's strategy is to increase 
revenue through run-time license fees. Any increase in the percentage of 
revenues attributable to run-time licenses will depend on Wind River's 
successful negotiation of run-time license agreements and on the successful 
commercialization by Wind River's customers of the underlying products. To 
the extent that such customers are not successful, Wind River may not be able 
to meet its objectives, and its business, financial condition and results of 
operations could be materially and adversely affected.

PRODUCT DEVELOPMENT 

The embedded real-time software industry faces a fragmented market 
characterized by ongoing technological developments, evolving industry 
standards and rapid changes in customer requirements.  Wind River's success 
depends and will continue to depend upon its ability to continue to develop 
and introduce in a timely manner new products that take advantage of 
technological advances, to identify and adhere to emerging standards, to 
continue to improve the functionality of its Tornado development environment 
and the scalability and functionality of the VxWorks product, to offer its 
products across a spectrum of microprocessor families used in the embedded 
systems market and to respond promptly to customers' requirements. Wind River 
has from time to time experienced delays in the development of new products 
and the enhancement of existing products. Such delays are commonplace in the 
software industry. There can be no assurance that Wind River will be 
successful in developing and marketing, on a timely basis or at all, 
competitive products, product enhancements and new products that respond to 
technological change, changes in customer requirements and emerging industry 
standards, or that Wind River's enhanced or new products will adequately 
address the changing needs of the marketplace.  Failure to develop and 
introduce new products and product enhancements in a timely manner would 
materially and adversely affect Wind River's business, financial condition 
and results of operations.

RISKS OF PRODUCT DEFECTS; PRODUCT AND OTHER LIABILITY

As a result of their complexity, software products may contain undetected 
errors or compatibility issues, particularly when first introduced or as new 
versions are released. There can be no assurance that, despite testing by 
Wind River and testing and use by current and potential customers, errors 
will not be found in new products after commencement of commercial shipments. 
The occurrence of such errors could result in loss of or delay in market 
acceptance of Wind River's products, which could have a material adverse 
effect on Wind River's business, financial condition and results of 
operations. Furthermore, although Wind River has not experienced material 
adverse effects resulting from any such errors to date, there can be no 
assurance that, despite testing by Wind River and testing and use by current 
and potential customers, errors will not be found in new products after 
commencement of commercial shipments, resulting in loss of or delay in market 
acceptance, which could have a material adverse effect upon Wind River's 
business, operating results and financial condition. Although Wind River's 
license and other agreements with its customers typically contain provisions 
designed to limit Wind River's exposure to potential product liability and 
other claims, these provisions may not be effective in all circumstances and 
in all jurisdictions. The increasing use of the Company's products for 
applications in systems that interact directly with the general public, 
particularly applications in transportation, medical systems and other 
markets where the failure of the embedded system could cause substantial 
property damage or personal injury, could expose the Company to significant 
product liability claims. In addition, the Company's products may be used for 
applications in mission-critical business systems where the failure of the 
embedded system could be linked to substantial economic loss.  Although Wind 
River has not experienced any product liability or economic loss claims to 
date, the sale and support of Wind River's products entail the risk of such 
claims. Wind River carries insurance against product liability risks and 
errors or omissions coverage.  However, there can be no assurance that such 
insurance will continue to be available to Wind River on commercially 
reasonable terms or at all. A product liability claim or claim for economic 
loss brought against Wind River in excess of or outside the limits of 

                                          13
<PAGE>

its insurance coverage, or a product recall involving Wind River's software, 
could materially and adversely affect Wind River's business, financial 
condition and results of operations.

RISKS ASSOCIATED WITH ACQUISITIONS

As part of its business strategy, Wind River has completed the acquisitions 
of Objective Software Technology, Ltd., Zinc Software Incorporated, and, in 
April 1999, certain assets of Xact, Inc., and has acquired equity interests 
in Emultek, Ltd., and 3Soft GmbH.  Wind River has also licensed certain 
technologies from Network Computer, Inc. Wind River expects to make 
additional acquisitions of, or significant investments in, businesses that 
offer complementary products, services and technologies. Any acquisitions or 
investments will be accompanied by the risks commonly encountered in 
acquisitions of businesses and technologies including, among other things, 
the difficulty of assimilating the operations and personnel of the acquired 
businesses, the potential disruption of Wind River's ongoing business, the 
inability to complete and integrate acquired technologies into new and 
existing products, the inability of management to maximize the financial and 
strategic position of Wind River, the potential for unidentified liabilities 
to disrupt the ongoing operations of Wind River, the maintenance of uniform 
standards, controls, procedures and policies and the impairment of 
relationships with employees and customers as a result of any integration of 
new management personnel. These factors could materially and adversely affect 
Wind River's business, results of operations or financial condition. 
Consideration paid for future acquisitions, if any, could be in the form of 
cash, stock, debt, rights to purchase stock or a combination thereof. 
Dilution to existing stockholders and to earnings per share may result to the 
extent that shares of stock or other rights to purchase stock are issued in 
connection with any such future acquisitions.

DEPENDENCE ON VME MARKET

A significant amount of Wind River's revenues historically has been derived 
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 Wind River believes that revenues from sales of products designed 
for embedded systems applications will account for an increasing percentage 
of Wind River's revenues in the future, Wind River expects revenues from the 
VME market to continue to be significant for the foreseeable future. Academic 
institutions and defense industry participants, which generate a significant 
portion of Wind River's VME revenues, are dependent on government funding, 
the continued availability of which is uncertain. Typically, Wind River's VME 
customers have received government funding prior to placing its product 
orders with Wind River. Any unanticipated future termination of government 
funding of VME customers could have a material adverse effect on Wind River's 
business, financial condition and results of operations.

MANAGEMENT OF GROWTH; DEPENDENCE ON KEY PERSONNEL; NEED FOR ADDITIONAL 
PERSONNEL

Wind River has experienced, and expects to continue to experience, 
significant growth in the number of employees, the scope and complexity of 
its operations and financial systems and the geographic area of its 
operations. Wind River's continued success will depend significantly on its 
ability to integrate new operations and new personnel. Wind River's ability 
to manage future expansion of its operations, if any, will require Wind River 
to continue to improve its financial and management controls, reporting 
systems and procedures on a timely basis and expand, train and manage its 
employee work force efficiently. There can be no assurance that Wind River 
will be able to do so successfully. Wind River's failure to do so could have 
a material adverse effect on Wind River's business, operating results and 
financial condition.  During fiscal 1998, Wind River purchased real property 
in the City of Alameda, California for $11.4 million and entered into an 
operating lease agreement for its new headquarters facility which was 
constructed on such property.  Wind River relocated its principal 
administrative, sales, marketing, product development and engineering 
facilities to the new headquarters facility during the fourth quarter in 
fiscal 1999.  As of January 31, 1999, the lessor has funded a total of $29.0 
million of construction costs and has committed to fund up to a maximum of 
$35 million. The operating lease payments will begin in May 1999. There can 
be no assurance that any such relocation will be accomplished efficiently, or 
that Wind River's operations will not be materially and adversely affected by 
such relocation. Wind River's future performance depends to a significant 
degree upon the continued contributions of its key management, product 
development, marketing, sales, customer support and operations personnel, 
several of whom have joined Wind River only recently. In addition, Wind River 
believes its future success will depend in large part upon its ability to 
attract and retain highly-skilled managerial, product development, marketing, 
sales, 

                                          14
<PAGE>

customer support and operations personnel, many of whom are in great demand. 
Competition for such personnel is particularly intense in the San Francisco 
Bay Area, where Wind River is headquartered, and there can be no assurance 
that Wind River will be successful in attracting and retaining such 
personnel. The failure of Wind River to attract, integrate and retain the 
necessary personnel could have a material adverse effect on Wind River's 
business, financial condition and results of operations.

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS

During the fiscal years ended January 31, 1999, 1998 and 1997, Wind River 
derived approximately 32%, 29% and 34%, respectively, of its total revenue 
from sales outside of North America. Wind River expects that international 
sales will continue to generate a significant percentage of its total revenue 
in the foreseeable future. Wind River also expects to continue to make 
investments to expand further its international operations and to increase 
its direct sales force in Europe and Asia. There can be no assurance that 
these investments will result in commensurate increases in Wind River's 
international sales. International operations are subject to certain risks, 
including foreign government regulation; more prevalent software piracy; 
longer payment cycles; unexpected changes in, or imposition of, regulatory 
requirements, tariffs, import and export restrictions and other barriers and 
restrictions; greater difficulty in accounts receivable collection; 
potentially adverse tax consequences including restrictions on repatriation 
of earnings; the burdens of complying with a variety of foreign laws; 
staffing and managing foreign operations; political and economic instability; 
changes in diplomatic and trade relationships; possible recessionary 
environments in economies outside the United States; and other factors beyond 
the control of Wind River. There can be no assurance that such factors will 
not have a material adverse effect on Wind River's international sales and 
consequently, Wind River's business, operating results and financial 
condition. 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 Wind River's revenues in dollar terms or make 
Wind River's products more expensive and, therefore, potentially less 
competitive in foreign markets. Although Wind River attempts to reduce the 
impact of foreign currency fluctuations, there can be no assurance that Wind 
River's future results of operations will no be adversely affected by 
currency fluctuations.   Wind River enters into forward contracts to hedge 
the short-term impact of foreign currency fluctuations.  A portion of Wind 
River's international revenues are derived from the Asia Pacific region 
including Japan. During fiscal year 1999, economic uncertainty and related 
weakening of foreign currencies, particularly the Japanese yen, against the 
dollar, has occurred.  As a result, Wind River's future sales in this region 
may be adversely affected, which could have a material adverse effect on Wind 
River's business, financial condition and results of operations.  Wind River 
relies on distributors for sales of its products in certain foreign countries 
and, accordingly, is dependent on their ability to promote and support Wind 
River's 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, and such distributors are not subject 
to any minimum purchase or resale requirements. There can be no assurance 
that Wind River's international distributors will continue to purchase Wind 
River's products or provide them with adequate levels of support. Any changes 
in the relationships Wind River has with its international distributors may 
have a material adverse effect on Wind River's business, operating results 
and financial condition.

IMPACT OF THE YEAR 2000

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 or after January 1, 2000.  As a result, in 
approximately eight months, computer systems and/or software used by many 
companies will need to have been upgraded to comply with such "Year 2000" 
requirements.  Systems that do not properly recognize such information could 
generate erroneous data or fail.  Significant uncertainty exists in the 
software industry concerning the potential effects associated with such 
compliance.  Although Wind River believes its most current releases of its 
products, including third party software integrated into certain products, 
will neither cease to perform nor generate incorrect or ambiguous data or 
results solely due to a change in date to 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 ("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 

                                          15
<PAGE>

necessary software routines and programs for the accurate calculation, 
display, storage and manipulation of data involving dates would have a 
material adverse effect on its business, financial condition and results of 
operations.  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 could materially and 
adversely affect Wind River's business, financial condition and results of 
operations.  See -"Management's Discussion and Analysis of Financial 
Condition and Results of Operations, 'Year 2000' Issues"

LEVERAGE

In connection with the sale of 5% Convertible Subordinated Notes in fiscal 
1998, Wind River incurred $140 million in debt which resulted in an increase 
in its ratio of long-term debt to total capitalization. As a result of this 
additional indebtedness, Wind River's principal and interest obligations have 
increased substantially. The degree to which Wind River will be leveraged 
could materially and adversely affect Wind River's ability to obtain 
financing for working capital, acquisitions or other purposes and could make 
it more vulnerable to industry downturns and competitive pressures. Wind 
River's ability to meet its debt service obligations will be dependent upon 
Wind River's future performance, which will be subject to financial, business 
and other factors affecting operations of Wind River, many of which are 
beyond its control.

VOLATILITY OF STOCK PRICE

The market price of Wind River's common stock has fluctuated in the past, and 
is likely to fluctuate in the future. Wind River believes that various 
factors, including quarterly fluctuations in results of operations, 
announcements of new products by Wind River or by its competitors, and 
changes in the software industry in general may significantly affect the 
market price of its common stock. In addition, in recent years the stock 
market in general, and the shares of technology companies in particular, have 
experienced extreme price fluctuations. This volatility has had a substantial 
effect on the market prices of securities issued by Wind River and other high 
technology companies, often for reasons unrelated to the operating 
performance of the specific companies. The market prices of many high 
technology companies' stocks are at or near their historical highs and 
reflect price/earning ratios substantially above historical norms. There can 
be no assurance that the market price of the common stock will remain at or 
near its current level or that it will not experience significant volatility. 
In the past, following periods of volatility in the market price of a 
company's securities, securities class action litigation has often been 
instituted against that company. Such litigation, if instituted against Wind 
River, could result in substantial costs and a diversion of management 
attention and resources, which would have a material adverse effect on Wind 
River's business, financial condition and results of operations, even if Wind 
River is successful in such suits. Wind River's performance, market 
fluctuations, and general economic, political and market conditions such as 
recessions, may adversely affect the market price of Wind River's common 
stock.

ITEM 2.


PROPERTIES

During the fourth quarter in fiscal 1999, Wind River relocated its principal 
administrative, sales, marketing, product development and engineering 
facilities to a new headquarters facility in Alameda, California.  The new 
facility provides approximately 148,000 square feet of space.  Rental 
payments for the new facility will begin in May 1999 and will vary based on 
the total construction costs of the property, including capitalized interest 
and the LIBOR.  In March 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 to a fixed rate of 5.9%.  Rental expenses incurred in fiscal 
1999 amounted to approximately $1,126,000 for the previously leased 
facilities. Wind River leases a customer training facility in Alameda, 
California, which provides approximately 11,300 square feet of office space. 
The lease expires in December 2001. Wind River also leases other domestic 
sales offices in the United States and international sales and/or service 
facilities in Canada, the United Kingdom, Scotland, France, Germany, Sweden, 
Israel, Italy, Korea, Singapore and Japan.  Wind River incurred approximately 
$394,000 for the leased offices in Japan during fiscal year 1999.  These 
Japanese leases will expire in March and August 2000.

ITEM 3.


LEGAL PROCEEDINGS

From time to time, Wind River is subject to legal proceedings and claims in 
the ordinary course of business, including claims of alleged infringement of 
patents and other intellectual property rights.  Wind River is not currently 
aware of any legal proceedings or claims that Wind River believes will have, 
individually or in the aggregate, a material adverse effect on Wind River's 
business, financial position or results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS 
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion contains forward-looking statements that involve 
risks and uncertainties. Wind River's actual results could differ materially 
from those discussed in any forward-looking statements. Factors that could 
cause or contribute to such differences include, but are not limited to, 
those discussed in this section, as well as under the caption "Business", 
including "-Additional Risk Factors." All forward-looking statements included 
in this document are based on information available to Wind River on the date 
hereof, and Wind River assumes no obligation to update any such 
forward-looking statements. The following discussion should be read in 
conjunction with the consolidated financial statements and notes included 
elsewhere herein. 

Wind River was founded in 1983 to provide consulting and custom software 
development services for a variety of business clients. From its inception, 
Wind River directed its development efforts towards real-time and embedded 
system applications and released its first commercial product, 
VxWorks-Registered Trademark-, in 1987. Wind River subsequently broadened its 
product offerings and has become a leading provider of operating systems and 
development tools for the real-time embedded systems marketplace. Tornado, 
Wind River's flagship product, consists of three integrated components: the 
Tornado toolset, a set of cross-development tools and utilities; the VxWorks 
run-time system, a high-performance, scalable RTOS that executes on the 
target processor; and a full range of communications options.  During the 
past five years, Wind River has invested heavily in the development and 
introduction of its products and in the establishment of worldwide sales, 
distribution, customer support 

                                          20
<PAGE>

and consulting capabilities. Wind River markets its products on a worldwide 
basis through its direct sales force, distributors and value-added resellers. 
Wind River provides sales, marketing and product support for foreign 
customers through wholly-owned subsidiary companies in the United States, 
Europe and a majority-owned subsidiary in Japan.  During fiscal year 1998, 
Wind River received ISO 9001 certification.

Wind River typically charges a one-time fee for a development license and a 
run-time license fee for each copy of Wind River's operating system embedded 
in the customer's product. A key component of Wind River's strategy is to 
significantly increase revenue through run-time license fees. Any increase in 
the percentage of revenues attributable to run-time licenses will depend on 
Wind River's successful negotiation of run-time license agreements and on the 
successful commercialization by Wind River's customers of the underlying 
products. 

In May 1998, Wind River acquired Zinc Software, Incorporated, a privately 
held company that develops, markets and supports graphical application 
software.  In connection therewith, Wind River issued 339,917 shares of 
common stock in exchange for all of the outstanding stock of Zinc.  The 
acquisition was accounted for as a pooling of interests.  As the operations 
of Zinc were not material to Wind River's consolidated operations and 
financial position, the financial statements of Zinc have been recorded in 
Wind River's consolidated financial statements as of May 1, 1998.

RESULTS OF OPERATIONS

The following table sets forth certain consolidated income statement data and 
its percentage of revenues for the periods indicated.  These operating 
results are not necessarily indicative of results for any future periods.

YEARS ENDED JANUARY 31, 1999 AND 1998


REVENUES

Revenues for fiscal 1999 were $129.4 million compared to $92.4 million for 
fiscal 1998.  Product revenues consist of licensing fees from operating 
system and software development tool products and fees from embedded system 
run-time licenses.  Service revenues are derived from fees from software 
porting and development contracts, software maintenance and support 
contracts, customer training and consulting.  Maintenance contracts are 
generally sold separately from the products. The increase in revenues of 40% 
is due to increases in both Wind River's product revenues and service 
revenues. Product revenues accounted for approximately 75% and 73% of the 
total revenues in fiscal 1999 and 1998, respectively, with service revenues 
accounting for the balance of total revenue over this period.

Product revenues were $96.4 million for fiscal 1999 compared to $67.1 million 
for fiscal 1998. The increase of 44% in product revenues was due primarily to 
the continued acceptance of Wind River's products and increased run-time 
license revenues. Tornado was first introduced in fiscal 1996, and its sales 
have continued to grow as Tornado has become available for use with more host 
platforms and microprocessor targets. In addition, demand grew for Tornado in 
Windows-based customer development environments. Run-time license revenue has 
increased each year in conjunction with growing shipments of customers' 
products and systems that incorporate the VxWorks operating system.

Service revenues were $33.0 million for fiscal 1999 compared to $25.3 million 
for fiscal 1998.  The increase of 30% was primarily due to an increase in 
maintenance support agreements and training resulting from the increase in 
Wind River's installed base of Tornado software development environments and 
software applications provided to customers. Maintenance contracts are 
generally prepaid, with the revenue recognized ratably over the period of the 
contract. The deferred revenue relates primarily to customer prepayments 
under software maintenance and certain run-time agreements, which are 
recognized ratably over the life of the agreements and engineering services 
contracts and training arrangements, which are recognized as services are 
performed.

Revenues from international sales were $41.6 million for fiscal 1999 compared 
to $26.9 million for fiscal 1998.  International revenues accounted for 32% 
and 29% of total revenues for the fiscal years ended January 31, 1999 and 
1998, respectively.  Revenues from European sources increased 34% from fiscal 
1998 to 1999 while revenues from Japan increased 100% over the same periods.  
Wind River expects international sales to continue to represent a significant 
portion of revenues, although the percentage may fluctuate from period to 
period.  Revenues derived from indirect sales channels worldwide represented 
26% and 21% of total revenues in fiscal 1999 and 1998, respectively.  A 
significant portion of these indirect revenues are attributable to revenues 
from WRSKK.  Wind River sells products to WRSKK at discounts which 
approximate those offered to other independent distributors of Wind River's 
products. 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 Wind River's revenues in dollar terms or make Wind 
River's 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 Wind River's results of operations.  Wind River enters into forward 
contracts to hedge the short-term impact of foreign currency fluctuations.  
During fiscal 1999, economic uncertainty and related weakening of foreign 
currencies, particularly the Japanese yen, against the dollar, has occurred.  
As a result, Wind River's future sales in this region may be adversely 
affected which could have a material adverse effect on Wind River's business, 
results of operations and financial condition.  Revenues from Asia Pacific 
sources including Japan represented 47% and 38% of international revenues for 
the year ended January 31, 1999 and 1998, respectively.   (See "Business - 
Additional Risk Factors - Risks Associated with International Operations").  

COST OF PRODUCTS

Cost of products was $8.8 million for fiscal 1999 compared to $6.2 million 
for fiscal 1998.  Product-related cost of revenues as a percentage of product 
revenues remained at 9% for both fiscal 1999 and 1998.  As a result, gross 
profit margins for products remained constant at 91%.  Product-related costs 
include direct and indirect costs for the production and duplication of 
manuals and media for software products, as well as those relating to the 
packaging, shipping and delivery of the products 

                                          22
<PAGE>

to the customer. Product costs also include license and other direct purchase 
costs of third-party software that is distributed by or integrated into Wind 
River's products and the amortization of capitalized software development 
costs.  Amortization of capitalized software development costs included in 
cost of products amounted to $530,000 and $654,000 in fiscal 1999 and 1998, 
respectively. The unamortized portion of capitalized software development 
costs was $446,000 at January 31, 1999.

COST OF SERVICES

Cost of services was $12.9 million for fiscal 1999 compared to $9.6 million 
for fiscal 1998.  Service related cost of revenues as a percentage of service 
revenues was 39% and 38% for fiscal 1999 and 1998, respectively, resulting in 
gross profit margin for services of 61% and 62%, respectively.  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 
investment in developing new services offerings, including consulting, and 
the addition of services professionals.  Wind River expects that customer 
support costs will increase in absolute dollars as Wind River continues to 
increase customer support staff and customer support capabilities.

SELLING AND MARKETING EXPENSES

Selling and marketing expenses were  $45.3 million for fiscal 1999 compared 
to $33.1 million for fiscal 1998.  The increase resulted primarily from 
increases in sales and marketing personnel both domestically and 
internationally and increased advertising.  As a percentage of total 
revenues, selling and marketing expenses were 35% and 36% for fiscal 1999 and 
1998, respectively. This decrease was attributable to a growing revenue base 
and more effective utilization of personnel.  The increase of 37% from fiscal 
1998 to 1999 in absolute dollars resulted primarily from the growth of sales 
and marketing personnel and field engineers and related costs and increases 
in expenses related to marketing and advertising programs and third-party 
marketing costs for product introductions and promotions.  During the fourth 
quarter of fiscal year 1999, Wind River announced and launched the 
introduction of Tornado II, an enhanced version of its integrated development 
environment.  Launch and introduction activities are expected to continue at 
least until the third quarter of fiscal year 2000.  Wind River expects that 
sales and marketing expenses will increase in absolute dollars as Wind River 
continues to expand its sales and marketing staff.

PRODUCT DEVELOPMENT AND ENGINEERING EXPENSES

Product development and engineering expenses were $17.6 million for fiscal 
1999 compared to $12.0 million for fiscal 1998, an increase of 47%.  As a 
percentage of revenues, product development and engineering expenses 
increased from 13% to 14% from fiscal 1998 to 1999.  The absolute dollar 
increase in product development and engineering expense is primarily due to 
the increase in staff and associated support for engineers to expand and 
enhance Wind River's product line, including the Tornado II integrated 
development environment.  Wind River believes that product development and 
engineering expenses will increase in absolute dollars as it continues to 
invest in developing new products, applications and product enhancements.

GENERAL AND ADMINISTRATIVE EXPENSES

General and administrative expenses were $7.7 million for fiscal 1999 
compared to $6.3 million for fiscal 1998, an increase of 22%.  As a 
percentage of revenues, general and administrative expenses decreased to 6% 
in fiscal 1999 from 7% in fiscal 1998.  The increase in absolute dollars was 
primarily due to the growth in worldwide staff and infrastructure investments 
in the areas of information systems, finance and administration.  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 compliance with Year 2000 requirements.  Wind River 
anticipates its financial and production systems will be operational in the 
third quarter of fiscal year 2000. Wind River believes that general and 
administrative expenses will increase in absolute dollars as it continues to 
invest in worldwide staff and infrastructure in the areas of information 
systems, finance and administration.

ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT

On December 31, 1997, Wind River entered into an OEM license agreement with 
NCI to license the right to access and modify the source code version of 
certain NCI technology and to duplicate, distribute and sublicense the object 
code version of such modified source code included with certain of Wind 
River's future products.  Under this agreement, Wind River paid $9.8 million 
for non-exclusive, restricted, perpetual rights to the technology and 
$200,000 for NCI engineering services incurred prior to source code delivery. 
In addition, selected elements of the NCI technology require Wind River to 
pay additional per unit royalties in the event Wind River's future sales of 
products that include the modified NCI technology exceed specified volume 
levels.  The licensed source code will be ported by Wind River to its 
VxWorks, IxWorks, WiSP and other real time embedded operating systems and 
will become a component of future products.  At the date the source code was 
acquired, there were no working models of such products incorporating the 
licensed technology and because of the restrictive nature of the license 
agreement, there were no alternative future uses for such technology in 
research and development.  Accordingly, the aggregate purchase price of $10 
million was expensed immediately as in-process research and development. 

On January 30, 1998, Wind River acquired Objective Software Technology, Ltd. 
("OST"), a privately held Scotland-based company that designs and markets 
visualization tools for development of embedded systems.  The acquisition was 
accounted for using the purchase method of accounting. Accordingly, the 
purchase price has been allocated to the assets purchased and the liabilities 
assumed based upon the fair values at the date of acquisition.   The excess 
of the purchase price over the fair market value of the net tangible assets 
acquired aggregated approximately $6.1 million, of which $4.1 million was 
allocated to in-process research and development and expensed immediately.   
Wind River used the discounted cash flow ("DCF") approach to determine the 
fair value of OST and its identifiable assets, including the value of the 
products in the development stage which were not considered to have reached 
technological feasibility. The DCF approach includes an analysis of the 
markets, completion costs, cash flows, other required assets, contributions 
made by core technology, and risks associated with achieving such cash flows. 
The balance of the excess acquisition cost was allocated to acquired 
technology ($2.0 million) which is being amortized over three years.  

Wind River incurred approximately $1.0 million of other non-merger 
incremental costs associated with these acquisitions which were included in 
the in-process research and development write-offs.

OTHER INCOME AND EXPENSE

Other income and expense includes interest income earned from the investment 
of excess cash, interest expense incurred on the 5.0% Convertible 
Subordinated Notes, due in 2002 (the "Notes") issued in July 1997, gains and 
losses related to inter-company foreign currency transactions and income and 
losses related to the 30% minority interest held by the Japanese participants 
in WRSKK.  

Interest income was $13.6 million for fiscal 1999 compared to $7.6 million 
for fiscal 1998.  The increase is primarily due to higher average cash and 
cash equivalent and investment balances, primarily due to the cash received 
from the issuance of the Notes, and to the transition of Wind River's 
investment portfolio from tax-free investments to taxable investments.

Interest expense and other was $8.7 million for fiscal 1999 compared to $4.2 
million for fiscal 1998.  The increase in interest expense is primarily 
related to the interest incurred for the entire year in fiscal year 1999 on 
the Notes and amortization of certain issuance costs associated with the 
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.

PROVISION FOR TAXES 

The effective tax rate was 37.7% for fiscal 1999 compared to 63.6% for fiscal 
1998.  The higher effective consolidated tax rate in fiscal 1998 resulted 
from a portion of the write-off of certain acquired in-process research and 
development being non-deductible. The overall changes in the effective tax 
rates result primarily from the difference between foreign and domestic tax 
rates and 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.

YEARS ENDED JANUARY 31, 1998 AND 1997


REVENUES

Revenues for fiscal 1998 were $92.4 million compared to $64.0 million for 
fiscal 1997.  The increase in revenues of 44% is due to increases in both 
Wind River's product revenue and services revenues. Product revenues 
accounted for approximately 73% and 72% of the total revenues in fiscal 1998 
and 1997, respectively, with service revenues accounting for the balance of 
total revenue over this period.

Revenues from the sale of products was $67.1 million for fiscal 1998 compared 
to $46.4 million for fiscal 1997.  The increase of 45% in product revenues 
was due primarily to the continued acceptance of Wind River's products and 
increased run-time license revenues.

Wind River's service revenues were $25.3 million for fiscal 1998 compared to 
$17.6 million for fiscal 1997.  The increase of 43% was primarily due to an 
increase in maintenance support agreements and training resulting from the 
increase in Wind River's installed base of Tornado software development 
environment and software applications provided to customers and engineering 
services contracts primarily related to porting Wind River's VxWorks 
operating system to microprocessor families.

Revenues from international sales were $26.9 million for fiscal 1998 compared 
to $22.1 million for fiscal 1997.  International revenues accounted for 29% 
and 34% of total revenues for the fiscal years ended January 31, 1998 and 
1997, respectively.  Revenues from European sources increased 35% from fiscal 
1997 to 1998 while revenues from Japan decreased 7% over the same periods. 
Revenues derived from indirect sales channels worldwide represented 21% and 
23% of total revenues in fiscal 1998 and 1997, respectively.  A significant 
portion of these indirect revenues are attributable to revenue from WRSKK.  
Revenues from Asia Pacific sources including Japan represented 38% and 44% of 
international revenues for the year ended January 31, 1998 and 1997, 
respectively.   (See "Business - Additional Risk Factors: Risks Associated 
with International Operations").  

COST OF PRODUCTS

Cost of products was $6.2 million for fiscal 1998 compared to $4.6 million 
for fiscal 1997.  Product-related cost of revenues as a percentage of product 
revenues decreased from 10% to 9% from fiscal 1997 and 1998.  The decrease is 
due to the increase in fees generated from run-time licenses.  The costs 
associated with fees from run-time licenses are significantly less than the 
costs required to generate fees for licenses for software products. 
Amortization of capitalized software development costs included in cost of 
products amounted to $654,000 and $600,000 in fiscal 1998 and 1997, 
respectively. 

COST OF SERVICES

Cost of services was $9.6 million for fiscal 1998 compared to $7.0 million 
for fiscal 1997.  Service related cost of revenues as a percentage of service 
revenues was 38% and 39% for fiscal 1998 and 1997, respectively.  The 
increase in costs of service revenues is due to investment in developing new 
services offerings and the addition of service professionals.

SELLING AND MARKETING EXPENSES

Selling and marketing expenses were  $33.1 million for fiscal 1998 compared 
to $23.9 million for fiscal 1997 or 36% and 37% of total revenues, 
respectively. This decrease was attributable to a growing revenue base and 
more effective utilization of personnel. The increase of 38% from fiscal 1997 
to 1998 resulted primarily from increases in sales and marketing personnel 
both domestically and internationally and increased advertising and 
third-party marketing costs for product introductions and promotions. 

PRODUCT DEVELOPMENT AND ENGINEERING EXPENSES

Product development and engineering expenses were $12.0 million for fiscal 
1998 compared to $7.7 million for fiscal 1997, an increase of 55%.  As a 
percentage of revenues, product development and engineering expenses 
increased from 12% to 

                                          25
<PAGE>

13% from fiscal 1997 to 1998.  The dollar increase in product development and 
engineering expense is primarily due to the increase in staff and associated 
support for engineers to expand and enhance Wind River's product line.  

GENERAL AND ADMINISTRATIVE EXPENSES

General and administrative expenses were $6.3 million for fiscal 1998 
compared to $5.0 million for fiscal 1997, an increase of 25%.  As a 
percentage of revenues, general and administrative expenses decreased to 7% 
in fiscal 1998 from 8% in fiscal 1997.  The increase in absolute dollars was 
primarily due to the growth in worldwide staff and infrastructure investments 
in the areas of information systems, finance and administration. 

OTHER INCOME AND EXPENSE

Interest income was $7.6 million for fiscal 1998 compared to $2.5 million for 
fiscal 1997.  The increase is primarily due to higher average cash and cash 
equivalent and investment balances which were obtained through the issuance 
of the Notes in July 1997 and cash received in a secondary offering to the 
public of common stock in July 1996.

Interest expense and other was $4.2 million for fiscal 1998 compared to $0 
for fiscal 1997.  The increase in interest expense is primarily related to 
the interest paid on the Notes and amortization of certain issuance costs 
associated with the 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.

PROVISION FOR TAXES 

The effective tax rate was 63.6% for fiscal 1998 compared to 37.2% for fiscal 
1997.  The higher effective consolidated tax rate in fiscal 1998 resulted 
from a portion of the write-off of certain acquired in-process research and 
development being non-deductible. The overall changes in the effective tax 
rates result primarily from the difference between foreign and domestic tax 
rates and 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 January 31, 1999, Wind River had working capital of approximately $56 
million and cash and investments of approximately $207 million, which include 
investments with maturities of greater than one year of $156 million.  Wind 
River invests primarily in instruments that are highly liquid and of 
investment grade.

In fiscal 1999, Wind River's operating activities provided net cash of $31.0 
million due primarily to net income, the tax benefit related to employee 
stock option exercises, and the non-cash impact of depreciation and 
amortization. These sources of cash were partially offset by increases in 
accounts receivable and prepaid and other assets.  The increase in accounts 
receivable is due to the increased sales activities in response to higher 
customer demand for Wind River's products and services.  The increase in 
prepaid and other current assets is primarily due to interest receivable on 
investments and prepaid foreign and state taxes.

In fiscal 1999, Wind River's investing activities used net cash of $88.8 
million. Uses of cash relating to the acquisition of equipment, purchases of 
investments and purchases of investments held as collateral for the operating 
lease and the accreting interest rate swap were partially offset by cash 
provided from the sale of investments.  As Wind River transitioned its 
investment portfolio from short-term to long-term investments, its long-term 
investments increased by $95 million.  Restricted cash increased primarily 
due to the increased collateral funding for the operating lease of Wind 
River's new headquarters.  The collateral consists of direct obligations of 
the United States government, with the majority being long-term investments.

Wind River's financing activities used net cash of $522,000.  Cash provided 
by the issuance of Common Stock for stock option exercises was offset by 
treasury stock repurchases pursuant to Wind River's ongoing Common Stock 
repurchase program.  During fiscal 1999, Wind River repurchased approximately 
397,000 shares of Common Stock at an aggregate cost of approximately $10 
million.  In January 1999, the Board of Directors increased the amount of the 
Common Stock to be repurchased each quarter to $4.0 million per quarter.

In July 1997, Wind River issued $140 million of 5% Convertible Subordinated 
Notes (the "Notes"), which mature on August 1, 2002. The Notes are 
subordinated to all existing and future senior debt and are convertible into 
shares of Wind River's Common Stock at a conversion price of $32.33 per 
share. The Notes are redeemable at the option of Wind River, in whole or in 
part, at any time on and after August 2, 2000 at 102% of the principal amount 
initially, and thereafter at prices declining to 100% at maturity, in each 
case plus accrued interest.  Each holder of these Notes has the right, 
subject to certain conditions and restrictions, to require Wind River to 
offer to repurchase all outstanding Notes, in whole or in part, owned by such 
holder, at specified repurchase prices plus accrued interest upon the 
occurrence of certain events.  The $5.1 million of costs incurred in 
connection with the offering are included in prepaid and other assets.  These 
unamortized costs are being amortized to interest expense over the 5-year 
term of the Notes using the straight-line method, which approximates the 
effective interest method. Interest on the Notes began accruing July 31, 1997 
and is payable semi-annually on February 1 and August 1, commencing on 
February 1, 1998.

In fiscal 1998, Wind River purchased real property in the City of Alameda, 
California for $11.4 million.  The property has been developed for Wind 
River's new headquarters facility.  Wind River has incurred an additional 
$2.2 million for related land improvements.

In fiscal 1998, Wind River entered into an operating lease agreement for its 
new headquarters facility being constructed on the land Wind River purchased 
in Alameda, California.  As of January 31, 1999, the lessor has funded a 
total of $29.0 million of construction costs and has committed to fund up to 
a maximum of $35 million.  The operating lease payments will begin in May 
1999 and will vary based on the total construction costs of the property, 
including capitalized interest, and the LIBOR.  

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%.  The 
notional amount of the swap under the agreement is scheduled to increase in 
relation to the funds used to construct Wind 

                                          28
<PAGE>

River's new headquarters.  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 agreement matures at the same time as the operating 
lease expires. The amounts potentially subject to credit risk (arising from 
the possible inability of counterparty to meet the term of the contract) are 
generally limited to the amounts, if any, by which the counterparty's 
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.

Construction of the new headquarters building was completed in the first 
quarter of fiscal year 2000.  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 $35 million 
funding obligation.  Wind River is also required to deposit 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 
January 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 that Wind River's working capital and cash flow generated 
from operations are sufficient to meet its working capital requirements for 
planned expansion, product development and capital expenditures for at least 
the next twelve months.

"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 eight 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 

                                          29
<PAGE>

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 initiated a program designed to 
address the most critical Year 2000 items that would affect its products, its 
worldwide business systems, and the operations of the following functions: 
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 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 third quarter of 
1999.  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, Wind River believes it has completed approximately 85% of the work 
required to obtain Year 2000 Compliance. Wind River expects to incur costs of 
approximately $3.5 million to implement its financial reporting system.  As 
of January 31, 1999, Wind River has incurred $1.1 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 first quarter of 

                                          30
<PAGE>

1999.  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 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/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 Wind River's current assessment, it does not 
expect that the Euro conversion will have a material adverse effect on its 
business, financial condition or results of operations.  

RECENT ACCOUNTING PRONOUNCEMENTS

In April 1998, the American Institute of Certified Public Accountants 
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the 
Costs of Computer Software Developed or Obtained for Internal Use" ("SOP 
98-1").  SOP 98-1 provides guidance for determining whether computer software 
is internal-use software and on accounting for the proceeds of computer 
software originally developed or obtained for internal use and then 
subsequently sold to the public. It also provides guidance on capitalization 
of the costs incurred for computer software developed or obtained for 
internal use.   Wind River believes that the adoption of SOP 98-1 will not 
have a material impact on its consolidated financial statements.  SOP 98-1 
will be effective for Wind River's consolidated financial statements for the 
fiscal year ending January 31, 2000.

In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS 
No. 133, "Accounting for Derivative Instruments and Hedging Activities" 
("SFAS 133").  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.  SFAS 133 will 
be effective for Wind River's consolidated financial statements for the 
fiscal year ending January 31, 2001. Wind River has not yet determined the 
impact, if any, of adopting this statement.

In December 1998, the AICPA released SOP 98-9, "Modification of SOP 97-2, 
'Software Revenue Recognition' with Respect to Certain Transactions" ("SOP 
98-9").  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 will be effective for transactions that 
are entered into in fiscal years beginning after March 15, 1999. Retroactive 
application is prohibited. We are evaluating the requirements of SOP 98-9 and 
the effects, if any, on our current revenue recognition policies.


ITEM 7A.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE SENSITIVITY

Wind River's exposure to market risk for changes in interest rates relates 
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 that an immediate 100 basis point move in interest rates 
affecting Wind River's floating and fixed rate financial instruments as of 
January 31, 1999 would have an immaterial effect on Wind River's pretax 
earnings.  Wind River also believes that 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.  At January 31, 1999, 
Wind River had outstanding forward contracts to hedge Japanese Yen with 
notional amounts totaling approximately $3.7 million.

The unrealized gains and losses on the outstanding forward contracts at 
January 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 January 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.

                                          32
<PAGE>

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 January 31, 1999, the notional amount of 
the accreting interest rate swap was $24.5 million.  The estimated fair value 
at January 31, 1999 was negligible. 

EQUITY PRICE RISK

Wind River owns 633,752 shares of common stock of Emultek, Inc., an Israeli 
corporation.  Wind River purchased the common stock prior to Emultek's public 
offering at a price of $7.50 per share.  Emultek went public in July 1998, 
and at January 31, 1999, the closing price of Emultek's stock was $4.75 per 
share.  Wind River values this investment using the closing price of the 
stock at the end of each month.  As a result, Wind River reflects this 
investment on our balance sheet at January 31, 1999 at its market value of 
approximately $3.0 million, with the unrealized gains and losses excluded 
from earnings and reported in the accumulated other comprehensive income 
component of stockholders' equity.  At March 31, 1999, the closing price of 
Emultek's stock was $7.69.

                              WIND RIVER SYSTEMS, INC.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1: OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Wind River Systems, Inc. and its subsidiaries are engaged in developing and 
marketing operating systems and software development tools for creating 
real-time and embedded applications.  Wind River's flagship product, TORNADO, 
is a scalable, cross-development environment that enables engineers to 
develop embedded applications on a host workstation or PC and download the 
code via a network or other communication channel to a real-time operating 
system ("RTOS") that runs on all significant 32- and 64- bit embedded target 
microprocessors. TORNADO consists of the Tornado toolset, VxWorks, an RTOS, 
and a full range of communications options.

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of Wind River and 
its wholly owned subsidiaries: Wind River Systems International, Inc., a 
United States corporation; Wind River Systems, E.C., S.A.R.L., a French 
corporation; Wind River Systems GmbH, a German corporation; Wind River 
Systems Italia, S.r.l, an Italian corporation; Wind River Systems UK, Ltd., a 
United Kingdom corporation; Wind River Systems Scotland Ltd., a Scottish 
corporation; Zinc Software, Incorporated, a United States Corporation; and 
its majority-owned subsidiary Wind River Systems K.K. ("WRSKK"), a Japanese 
corporation.  All significant inter-company accounts and transactions have 
been eliminated.

Wind River has a fiscal year end of January 31. The international 
subsidiaries have fiscal year-ends of December 31. The consolidated financial 
statements include the subsidiaries' accounts as of December 31. 

Certain amounts in the fiscal 1998 financial statements have been 
reclassified to conform to the fiscal 1999 presentation.

CASH AND CASH EQUIVALENTS

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. 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. Fair value is determined based 
upon the quoted market prices of the securities as of the balance sheet date.

INVESTMENTS

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 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 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.

CONCENTRATION OF CREDIT RISK

Wind River's financial instruments that are exposed to concentrations of 
credit risk consist primarily of cash, cash equivalents, investments, and 
accounts receivable. Wind River's investments consist of investment grade 
securities managed by qualified professional investment managers. The 
investment policy limits Wind River's exposure to concentration of credit 
risk. Wind River's accounts receivable result primarily from software sales 
to a broad customer base both domestically and internationally and are 
typically unsecured. Wind River performs on-going credit evaluations of its 
customers' financial condition, limits the amount of credit when deemed 
necessary and maintains allowances for potential credit losses; historically, 
such losses have been immaterial.  As a consequence, concentrations of credit 
risk are limited.

FAIR VALUE OF FINANCIAL INSTRUMENTS

For certain of Wind River's financial instruments, including cash and cash 
equivalents, short-term investments, accounts receivable and accounts 
payable, the carrying amounts approximate fair value due to their short 
maturities.  The estimated fair value for the convertible subordinated notes 
(with a carrying amount of $140 million at January 31, 1999) is approximately 
$135.8 million at January 31, 1999.  The fair value for the convertible 
subordinated notes is based on quoted market prices.

LAND AND EQUIPMENT

Land and equipment are stated at cost. Depreciation on equipment is computed 
using the straight-line method over the estimated useful lives of the assets, 
which is generally two to four years for computer equipment and four to ten 
years for furniture and equipment. Leasehold improvements are amortized over 
the term of the related lease or useful economic life, if shorter. 

SOFTWARE DEVELOPMENT COSTS

Wind River accounts for software development costs in accordance with SFAS 
86, "Accounting for the Costs of Computer Software to Be Sold, Leased or 
Otherwise Marketed."  Costs incurred to establish the technological 
feasibility of a computer software product are considered research and 
development costs and are expensed as incurred. When the technological 
feasibility of a software product has been established using the working 
model approach, development costs are capitalized. Capitalization of these 
costs ceases when the product is considered available for general release to 
customers. Amortization of capitalized software development costs is provided 
on a product-by-product basis at the greater of the amount computed using (a) 
the ratio of current gross revenues for a product to the total of current and 
anticipated future gross revenues or (b) the straight-line method over the 
remaining estimated economic life of the product. Generally, an original 
estimated economic life of eighteen months is assigned to capitalized 
software development costs.  Amortization of capitalized software costs is 
charged to cost of product revenues.  Research and development expenditures 
are charged to research and development in the period incurred. The 
amortization of capitalized software costs which were charged to cost of 
product revenues during fiscal 1999, 1998 and 1997 were $530,000, $654,000 
and $600,000, respectively.  At January 31, 1999 and 1998, Wind River had 
capitalized software costs of $446,000 and $977,000, respectively.  

OTHER ASSETS

Other assets include bond issuance costs, purchased technology, capitalized 
software development costs, equity investments, and deposits.  Bond issuance 
costs are amortized over five years and purchased technology is amortized 
over three years. 

Wind River evaluates the recoverability of its property and equipment and 
intangible assets in accordance with SFAS 121, "Accounting for the Impairment 
of Long-Lived Assets and for Long-Lived Assets to be Disposed of."  SFAS 121 
requires recognition of impairment of long-lived assets in the event the net 
book value of such assets exceeds the future undiscounted cash flows 
attributable to such assets.  Accordingly, Wind River evaluates asset 
recoverability at each balance sheet date or when an event occurs that may 
impair recoverability of the asset. Wind River determines the recoverability 
of the carrying amount of each intangible asset by reviewing the following 
factors: the undiscounted value of expected operating cash flows in relation 
to its net capital investments, the estimated useful or contractual life of 
the intangible asset, the contract or product 

                                          41
<PAGE>

supporting the intangible asset, and in the case of purchased technology and 
capitalized software development costs, Wind River periodically reviews the 
recoverability of the assets value by evaluating its products with respect to 
technological advances, competitive products and the needs of its customers.

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. The adoption of SOP 97-2 and 
SOP 98-4 did not have a material impact on Wind River's current licensing or 
revenue recognition practices. 

Product revenues consist of licensing fees from operating system and software 
development tool products and fees from embedded system run-time licenses. 
Service revenues are derived from fees from software porting and development 
contracts, software maintenance and support contracts, customer training and 
consulting. Maintenance contracts are generally sold separately from the 
products. Wind River's customers consist of end users, distributors, original 
equipment manufacturers, system integrators and value-added resellers.

Product revenues are generally recognized at the time of shipment or upon the 
delivery of a product master in satisfaction of non-cancelable contractual 
agreements provided that collection of the resulting receivable is probable, 
the fee is fixed or determinable and vendor-specific objective evidence 
("VSOE") exists to allocate the total fee to all delivered and undelivered 
elements of the arrangement.  Any maintenance included in these arrangements 
is deferred based on VSOE and recognized ratably over the term of the 
arrangement.  Service revenues from engineering services contracts are 
generally recognized on the percentage-of-completion basis.  Service revenues 
from software maintenance, support and update fees (post-contract support) 
are recognized ratably over the contract period.  Services revenue from 
training and consulting are recognized when the services are provided.        
                     

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 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 will be effective for 
transactions that are entered into in fiscal years beginning after March 15, 
1999. Retroactive application is prohibited. We are evaluating the 
requirements of SOP 98-9 and the effects, if any, on our current revenue 
recognition policies.

FOREIGN CURRENCY TRANSLATION

The functional currency of foreign subsidiaries is the local currency. 
Accordingly, assets and liabilities of the subsidiaries are translated using 
the exchange rates in effect at the end of the period, while income and 
expense items are translated at average rates of exchange during the period.  
Gains or losses from translation of foreign operations where the local 
currency is the functional currency are included as other comprehensive 
income or loss. The net gains and losses resulting from foreign currency 
transactions are recorded in net income in the period incurred and were not 
significant for any of the periods presented.

STOCK-BASED COMPENSATION PLANS

Wind River accounts for stock-based employee compensation arrangements in 
accordance with the provisions of Accounting Principles Board Opinion No. 25, 
"Accounting for Stock Issued to Employees," ("APB 25") and complies with the 
disclosure provisions of SFAS 123, "Accounting for Stock Based Compensation." 
Under APB 25, compensation cost is recognized over the vesting period based 
on the difference, if any, on the date of grant between the fair market value 
of Wind River's stock and the amount an employee must pay to acquire the 
stock. Wind River's policy is to grant options with an 

                                          42
<PAGE>

exercise price equal to the quoted market price of Wind River's stock on the 
grant date.  Accordingly, no compensation expense has been recognized for its 
stock option plans.  

NET INCOME PER SHARE

Net income per share includes 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.  
Dilutive common equivalent shares consist of stock options and warrants 
(using the treasury stock method) and convertible subordinated notes (using 
the if converted method).  Common equivalent shares are excluded from the 
computation if their effect is anti-dilutive.  

RECENT ACCOUNTING PRONOUNCEMENTS

In April 1998, the AICPA issued SOP 98-1, "Accounting for the Costs of 
Computer Software Developed or Obtained for Internal Use."  SOP 98-1 provides 
guidance for determining whether computer software is internal-use software 
and on accounting for the proceeds of computer software originally developed 
or obtained for internal use and then subsequently sold to the public.  It 
also provides guidance on capitalization of the costs incurred for computer 
software developed or obtained for internal use.   Wind River believes that 
the adoption of SOP 98-1 will not have a material impact on its consolidated 
financial statements.  SOP 98-1 will be effective for Wind River's 
consolidated financial statements for the fiscal year ending January 31, 2000.

In June 1998, the 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.  SFAS 133 
will be effective for Wind River's consolidated financial statements for the 
fiscal year ending January 31, 2001. Wind River has not yet determined the 
impact, if any, of adopting this statement.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.


NOTE 2: ACQUISITIONS

In May 1998, Wind River acquired Zinc Software, Incorporated, a privately 
held company that develops, markets and supports graphical application 
software.  In connection therewith, Wind River issued 339,917 shares of 
common stock in exchange for all of the outstanding stock of Zinc.  The 
acquisition was accounted for as a pooling of interests.  As the operations 
of Zinc were not material to Wind River's consolidated operations and 
financial position, the financial statements of Zinc have been recorded in 
the consolidated financial statements as of May 1, 1998.

On December 31, 1997, Wind River entered into an OEM license agreement with 
NCI to license the right to access and modify the source code version of 
certain NCI technology and to duplicate, distribute and sublicense the object 
code version of such modified source code included with certain of Wind 
River's future products.  Under the agreement, Wind River paid $9.8 million 
for non-exclusive, restricted, perpetual rights to the technology and 
$200,000 for NCI engineering services incurred prior to source code delivery. 
 In addition, selected elements of the NCI technology require Wind River to 
pay additional per unit royalties in the event Wind River's future sales of 
products that include the modified NCI technology exceed specified volume 
levels.  The licensed source code will be ported by Wind River to its 
VxWorks, IxWorks, WiSP and 

                                          43
<PAGE>

other real time embedded operating systems and will become a component of 
future products.  At the date the source code was acquired, there were no 
working models of such products incorporating the licensed technology and 
because of the restrictive nature of the license agreement, there were no 
alternative future uses for such technology in research and development.  
Accordingly, the aggregate purchase price of $10 million was expensed 
immediately as in-process research and development. 

On January 30, 1998, Wind River acquired Objective Software Technology, Ltd. 
("OST"), a privately held Scotland-based company that designs and markets 
visualization tools for development of embedded systems.  The acquisition was 
accounted for using the purchase method of accounting. Accordingly, the 
purchase price has been allocated to the assets purchased and the liabilities 
assumed based upon the fair values at the date of acquisition.   The excess 
of the purchase price over the fair market value of the net tangible assets 
acquired aggregated approximately $6.1 million, of which $4.1 million was 
allocated to in-process research and development and expensed immediately.   
Wind River used the discounted cash flow ("DCF") approach to determine the 
fair value of OST and its identifiable assets, including the value of the 
products in the development stage which were not considered to have reached 
technological feasibility. The DCF approach includes an analysis of the 
markets, completion costs, cash flows, other required assets, contributions 
made by core technology, and risks associated with achieving such cash flows. 
The balance of the excess acquisition cost was allocated to acquired 
technology ($2.0 million) which is being amortized over three years.  

Wind River incurred approximately $1.0 million of other non-merger 
incremental costs associated with these acquisitions which were included in 
the in-process research and development write-offs.

Gross realized gains and losses from the sale of securities classified as 
available-for-sale were not material for the years ended January 31, 1999, 
1998 and 1997.  For the purpose of determining gross realized gains and 
losses, the cost of securities is based upon specific identification.


NOTE 5: DERIVATIVE FINANCIAL INSTRUMENTS

Wind River enters into foreign currency forward exchange contracts ("forward 
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 
reporting period are marked-to-market, with unrealized gains and losses 
included in net income as a component of other income (expense).  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 January 31, 1999, Wind 
River had outstanding forward contracts with notional amounts totaling 
approximately $3.7 million.  These contracts, which mature in less than 
ninety days, are hedges of certain foreign currency transaction exposures in 
the Japanese yen.  The difference between cost and estimated fair value at 
January 31, 1999 was negligible.

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 
(see Note 12).  The Swap Agreement effectively changes Wind River's interest 
rate exposure on its operating lease which is at one month LIBOR to a fixed 
rate of 5.9%.  The notional amount under the Swap Agreement is scheduled to 
increase in relation to the funds used to construct Wind River's new 
headquarters.  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 counterparty to meet the term of 
their contracts) are generally limited to the amounts, if any, by which the 
counterparty's obligations exceed the obligations of Wind River.

The effective consolidated tax rate in fiscal 1998 was higher due to the 
permanent difference resulting from the write-off of in-process research and 
development during the fourth quarter of fiscal 1998. In fiscal 1999, 1998 
and 1997, tax benefits resulting from the exercise of employee stock options 
amounting to $13.4 million, $7.0 million and $5.7 million, respectively, were 
credited to stockholders' equity and reduced income taxes payable.

Deferred tax assets (liabilities) which result from temporary differences in 
the recognition of certain revenues and expenses for financial and income tax 
reporting purposes consist of the following:

NOTE 7: CONVERTIBLE SUBORDINATED NOTES

In July 1997, Wind River issued $140 million of 5% Convertible Subordinated 
Notes (the "Notes"), which mature on August 1, 2002. The Notes are 
subordinated to all existing and future senior debt and are convertible into 
shares of Wind River's Common Stock at a conversion price of $32.33 per 
share. The Notes are redeemable at the option of Wind River, in whole or in 
part, at any time on or after August 2, 2000 at 102% of the principal amount 
initially, and thereafter at prices declining to 100% at maturity, in each 
case plus accrued interest.  Each holder of these Notes has the right, 
subject to certain conditions and restrictions, to require Wind River to 
offer to repurchase all outstanding Notes, in whole or in part, owned by such 
holder, at specified repurchase prices plus accrued interest upon the 
occurrence of certain events.  The $5.1 million of costs incurred in 
connection with the offering are included in prepaid and other assets.  These 
unamortized costs are being amortized to interest expense over the 5-year 
term of the Notes using the straight-line method, which approximates the 
effective interest method. Interest on the Notes began accruing July 31, 1997 
and is payable semi-annually on February 1 and August 1, commencing on 
February 1, 1998.

NOTE 8: COMPREHENSIVE INCOME

In February 1998, Wind River adopted SFAS 130, "Reporting 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.  The 
adoption of SFAS 130 had no impact on Wind River's results of operations.

Wind River's comprehensive income has been presented in the Consolidated 
Statements of Stockholders' Equity. As of January 31, 1999, accumulated other 
comprehensive loss consisted of foreign currency translation adjustments of 
$1,543,000 and unrealized loss on investments of $612,000.


NOTE 9: NET INCOME PER SHARE

In accordance with SFAS 128, the calculation of basic and diluted net income 
per share is presented below:

NOTE 10: COMMON STOCK

On May 24, 1996, March 10, 1997 and February 4, 1999, Wind River effected 
three-for-two splits of its Common Stock in the form of stock dividends.  Par 
value remained at $0.001 per share.  Accordingly, all share and per share 
amounts have been adjusted to give retroactive effect to these stock splits.

During fiscal year 1999, Wind River repurchased approximately 397,000 shares 
of Common Stock at an aggregate cost of approximately $10.0 million.  In 
January 1999, the Board of Directors increased the amount of the Common Stock 
to be repurchased per quarter at prevailing market prices or in negotiated 
transactions off the market to $4.0 million per quarter.

In May 1998, Wind River issued 339,917 unregistered shares of its Common 
Stock to the shareholders of Zinc Software, Incorporated in exchange for all 
of the then outstanding shares of Zinc.  In January 1999 Wind River issued 
337,500 of unregistered shares of its Common Stock to Innotech Corporation 
upon Innotech's exercise of a warrant issued in January 1995, for an 
aggregate exercise price of approximately $1.1 million.

NOTE 11: STOCK BASED COMPENSATION PLANS

As of January 31, 1999, Wind River had five stock-based compensation plans. 
Wind River accounts for its stock-based compensation plans in conformity with 
APB 25 and related Interpretations and has adopted the additional pro forma 
disclosure provisions of SFAS 123.  Accordingly, no compensation expense has 
been recognized for its four fixed stock option plans and its stock purchase 
plan.

The Amended and Restated 1987 Equity Incentive Plan (the "1987 Plan") allows 
for the issuance of options and other stock awards to Company employees and 
consultants to purchase a maximum of 14,175,000 shares of Common Stock. Stock 
options granted under the 1987 Plan may be incentive stock options or 
nonstatutory stock options.  Individuals owning more than 10% of Wind River's 
stock are not eligible to receive incentive stock options under the 1987 Plan 
unless the option's price is at least 110% of the fair market value of the 
Common Stock at the date of grant and the term of the option does not exceed 
five years from the date of grant. Nonstatutory stock options issued to 
holders of less than 10% of Wind River's stock may be granted at prices of at 
least 85% of the fair market value of the stock at the grant date and with 
expirations not to exceed ten years from the grant date, although Wind 
River's current practice is to grant options with exercise prices at least 
100% of the fair market value. Under the terms of the 1987 Plan, option 
vesting provisions are established by the Board of Directors when options are 
granted. Options generally will vest over four years, although options may be 
granted that vest upon achievement of performance criteria.  Unexercised 
options are automatically canceled three months after termination of the 
optionee's employment or other service with Wind River.

In April 1995, Wind River adopted the 1995 Non-Employee Directors' Stock 
Option Plan (the "Directors' Plan"). The Directors' Plan provides for 
automatic grants of nonstatutory stock options to purchase Common Stock of 
Wind River to directors of Wind River who are not employees of, or 
consultants to, Wind River or any affiliate of Wind River (Non-Employee 
Directors). The Directors' Plan allows for the issuance of options to 
purchase a maximum of 337,500 shares of Common Stock. Options issued are 
granted at prices of 100% of the fair market value of the Common Stock at the 
date of grant and with expirations of ten years from the grant date. Initial 
options granted to each Non-Employee Director vest in annual increments over 
a period of four years from the date of grant, commencing on the date one 
year after the date of grant of the initial options. Subsequent options shall 
become 100% vested at the end of the one-year period following the date of 
grant as long as the optionee has attended 75% of the meetings of the board 
and committees on which he serves. Unexercised options will terminate six 
months after such optionee's termination of all service with Wind River and 
its affiliates.

In April 1998, Wind River adopted the 1998 Non-Officer Stock Option Plan (the 
"Non-Officer Plan").  The Non-Officer Plan provides for grants of 
nonstatutory stock options to employees and consultants who are not officers 
or directors of Wind River.  An aggregate of 1,950,000 shares of Common Stock 
have been reserved for issuance under the Non-Officer Plan.  The exercise 
price of nonstatutory stock option granted under the Non-Officer Plan may not 
be less than 85 percent of the fair market value of the Common Stock on the 
date of grant.  All nonstatutory stock options may be granted under the 
Non-Officer Plan have a maximum term of 10 years.  Options generally will 
vest over four years, although options may be 

                                          48
<PAGE>

granted that vest upon achievement of performance criteria.  The Non-Officer 
Plan and options thereunder may be amended by the Board from time to time. 
The Non-Officer Plan will terminate on April 22, 2008. 

In June 1998, Wind River adopted the 1998 Equity Incentive Plan (the "1998 
Plan").  The 1998 Plan provides for grants of options and other stock awards 
to Company employees, directors and consultants to purchase a maximum of 
1,500,000 shares of Common Stock. Stock options granted under the 1998 Plan 
may be incentive stock options or nonstatutory stock options.  Individuals 
owning more than 10% of Wind River's stock are not eligible to receive 
incentive stock options under the 1998 Plan unless the option's price is at 
least 110% of the fair market value of the Common Stock at the date of grant 
and the term of the option does not exceed five years from the date of grant. 
Nonstatutory stock options issued to holders of less than 10% of Wind River's 
stock may be granted at prices of at least 85% of the fair market value of 
the stock at the grant date and with expirations not to exceed ten years from 
the grant date, although Wind River's current practice is to grant options 
with exercise prices at least 100% of the fair market value.  Under the terms 
of the 1998 Plan, option vesting provisions are established by the Board of 
Directors when options are granted. Options generally will vest over four 
years, although options may be granted that vest upon achievement of 
performance criteria.  Unexercised options are automatically canceled three 
months after termination of the optionee's employment or other service with 
Wind River.

The number of shares for which options under these four plans were 
exercisable was approximately 2,338,000, 2,603,000, and 2,054,000 at January 
31, 1999, 1998 and 1997, respectively. Activity under the 1987 Plan, the 
Directors' Plan, the 1998 Plan and the Non-Officer Plan is summarized as

In March 1993, Wind River adopted the Employee Stock Purchase Plan (the 
"Purchase Plan").  An aggregate of 1,350,000 shares of Common Stock are 
authorized for issuance under the Purchase Plan. Under the Purchase Plan, the 
Board of Directors may authorize participation by eligible employees, 
including officers, in periodic offerings following the commencement of the 
Purchase Plan. Employees who participate in an offering can have up to 15% of 
their earnings withheld pursuant to the Purchase Plan. The amount withheld is 
used to purchase shares of Common Stock on specified dates determined by the 
Board. The price of Common Stock purchased under the Purchase Plan is equal 
to 85% of the lower of the 

                                          49
<PAGE>

fair market value of the Common Stock, determined by the closing price on the 
Nasdaq National Market, at the commencement date or the ending date of each 
six month offering period.

Sales under the Purchase Plan in fiscal 1999, 1998 and 1997 were 121,000, 
96,000 and 127,500 shares of Common Stock, respectively, at an average price 
of $20.28, $19.43 and $9.78, respectively. At January 31, 1999, 354,473 
shares of Common Stock were available for future purchase.

PRO FORMA DISCLOSURES

Under SFAS 123, the fair value of each option grant is estimated on the date 
of grant using the Black-Scholes model with the following assumptions used 
for grants during fiscal 1999, 1998 and 1997:

Wind River applies the provisions of APB 25 and related Interpretations in

The pro forma amounts include compensation expense related to fiscal 1999,

Purchase Plan only. The effects of applying SFAS 123 on pro forma disclosures 
of net income or loss and net income or loss per share for fiscal 1999, 1998 
and 1997 are not likely to be representative of the pro forma effects on net 
income and net income per share in future years.

</TABLE>

Rental expense for fiscal 1999, 1998 and 1997 was $3.1 million, $2.5 million 
and $2.0 million, respectively.

In fiscal 1998, Wind River entered into an operating lease agreement for its 
new headquarters facility being constructed on the land Wind River purchased 
in Alameda, California.  As of January 31, 1999, the lessor has funded a 
total of $29.0 million of construction costs and has committed to fund up to 
a maximum of $35 million.  The operating lease payments will begin in May 
1999 and will vary based on the total construction costs of the property, 
including capitalized interest, and the London interbank offering rate 
("LIBOR").  

Construction of the new headquarters building was completed in the first 
quarter of fiscal year 2000.  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 $35 million 
funding obligation.  Wind River is also required, periodically during the 
construction period, to deposit 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 January 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. 

From time to time, Wind River is subject to legal proceedings and claims in 
the ordinary course of business, including claims of alleged infringement of 
patents and other intellectual property rights.  Wind River is not currently 
aware of any legal proceedings or claims that Wind River believes will have, 
individually or in the aggregate, a material adverse effect on Wind River's 
financial position or results of operations.


NOTE 13: RELATED PARTY TRANSACTIONS

Wind River distributes its products in Japan through WRSKK, a joint venture 
in which Wind River owns a 70% equity interest. Innotech Corporation 
("Innotech"), Kobe Steel Ltd. and Nissin Electric Ltd., the other partners in 
the joint venture, each owns a 10% equity interest.  Wind River entered into 
distributor agreements with the three minority interest owners of WRSKK, 
Innotech, Kobe Steel, Ltd., and Nissin Electric Ltd., in March 1993, October 
1991, and October 1991, respectively. The Innotech agreement was amended in 
December 1995 to provide for an extended contract term and to issue to 
Innotech a warrant to purchase 337,500 shares of Wind River's Common Stock 
for $3.29 per share. The warrant was valued at $100,000 and charged to cost 
of sales in fiscal 1996. The warrant was exercised on January 26, 1999.

                                          51
<PAGE>

All products in Japan are sold through WRSKK's three master distributors. 
Revenues derived from master distributor transactions in Japan amounted to 
$17.0 million, $8.5 million, and $9.1 million in fiscal 1999, 1998 and 1997, 
respectively. The percentage of Japan revenues from Innotech in fiscal year 
1999, 1998 and 1997 was 53%, 32% and 58%, respectively. The percentage of 
Japan revenues from Kobe Steel Ltd. in fiscal year 1999, 1998 and 1997 was 
34%, 52% and 24%, respectively. The percentage of Japan revenues from Nissin 
Electric Ltd. in fiscal year 1999, 1998 and 1997 was 13%, 16% and 18%, 
respectively. Advances from the joint venture partners were approximately 
$310,000 and $1.9 million at January 31, 1999 and 1998, respectively.


NOTE 14: SEGMENT AND GEOGRAPHIC INFORMATION

Wind River has adopted SFAS 131, "Disclosures about Segments of an Enterprise 
and Related Information," effective for fiscal year 1999.  SFAS 131 
supersedes SFAS 14, "Financial Reporting for Segments of a Business 
Enterprise."  SFAS 131 changes current practice under SFAS 14 by establishing 
a new framework on which to base segment reporting and also requires interim 
reporting of segment information.  

Wind River operates in one industry segment - technology for embedded 
operating systems.  Management uses one measurement of profitability for its 
business.  Wind River markets its products and related services to customers 
in the United States, Canada, Europe and Asia Pacific.  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:
