                               PROSPECTUS SUMMARY

     The following summary highlights information that we present more fully
elsewhere in this prospectus. You should read this entire prospectus carefully.

                              BSQUARE CORPORATION

     We provide a broad range of products and services that facilitate the
integration of Microsoft Windows operating systems into a variety of devices we
call intelligent computing devices (ICDs), enhance the functionality of those
devices, and accelerate their deployment into the marketplace. Original
equipment manufacturers, semiconductor vendors, software developers, value added
resellers, internet service providers and network service providers rely on our
products and services to help bring customized intelligent computing devices and
intelligent computing device applications to market in a timely fashion. We have
been providing Windows CE-based software services since before the commercial
release of Windows CE in September 1996, and therefore we believe that we offer
a greater breadth and depth of Windows CE expertise than any of our current
competitors. In addition, in late 1999, we began offering Windows NT Embedded
integration services, thus expanding the breadth of our service offerings, and
in January 2000, our acquisition of BlueWater Systems broadened our product line
for developers of ICDs based on additional Windows operating systems including
Windows 98, Windows 2000, Windows NT and Windows NT Embedded. Our acquisition of
Mainbrace Corporation in May 2000 enables us to provide standard manufacturable
designs of popular intelligent computing devices such as Webpads, Web-phones,
Pocket PCs, E-books and portable data tablets, which together with our other
products and services offer customers a broad range of solutions to rapidly
bring products to market.

     Intelligent computing devices are an emerging class of products with
sophisticated processing power that are designed for specific computing and
communications applications. Examples of intelligent computing devices include
television "set-top boxes," which sit on top of television sets and provide
users with advanced cable TV services, sophisticated video gaming features and
Internet access; handheld and palm-size PCs; gaming systems; handheld industrial
data collectors; consumer "Internet appliances" such as kiosk terminals and
navigational devices in cars and trucks; and Windows-based terminals, Webpads,
E-books and Pocket PCs used both in the workplace and at home. Compared to
traditional computers, intelligent computing devices are often less expensive
and more adaptable in terms of their size, weight and shape, while still
providing sophisticated computing and communications capabilities, including
Internet connectivity.

     Increasingly, intelligent computing devices are able to connect directly to
the Internet, either through wired or wireless telecommunications systems. As
businesses and consumers increasingly use the Internet to transact business and
access information and as demand for smaller and more mobile devices grows,
original equipment manufacturers are developing new intelligent computing
devices to better meet the needs of end users. Because of space constraints and
other design and resource limitations inherent in the intelligent computing
device environment, original equipment manufacturers require a computer
operating system that is both scaleable and highly customizable, with lower
system requirements than traditional PC operating systems. There are several
different operating systems that can be used in intelligent computing devices.
Windows CE, a versatile and highly adaptable operating system modeled after
Microsoft Windows, is gaining market acceptance among original equipment
manufacturers as an operating system that meets these requirements. As increased
use of the Internet by consumers and businesses helps fuel the growth of the
intelligent computing device market, we believe that the market for Windows CE
will in turn benefit. In addition, the Windows NT Embedded operating system is
used for "computerizing" larger, more complex devices with a need for real time
functionality. Examples of devices for which Windows NT Embedded is
                                        1
<PAGE>   5

designed include Windows-based terminals, office machine equipment such as
printers, and telecommunications equipment such as routers and switching
equipment.

     We develop products and provide services that facilitate the development of
Windows CE-based intelligent computing devices. We generate revenue in four
distinct ways. First, we provide software code-writing and related engineering
services to Microsoft and semiconductor vendors to adapt Windows CE software to
different microprocessors and to enhance Windows CE's user-specific features and
functions. Second, we offer a comprehensive set of software products and
services that help enable original equipment manufacturers to cost-effectively
integrate Windows CE, NT Embedded and other Windows operating systems into their
intelligent computing devices. These offerings include original equipment
manufacturer adaptation kits, software development products, test programs and
Microsoft Windows CE licensing, along with engineering and quality assurance
services and training. Our service and product offerings are designed to ensure
that Windows works properly with the original equipment manufacturer's computer
boards, which are the internal hardware constituting the core of their
intelligent computing devices. We also offer software engineering services for
the integration of Window NT Embedded into ICDs, and for other Windows-based
operating systems we offer the BlueWater Systems software development products.
Third, we license a wide range of Windows-based software applications to
original equipment manufacturers, value added resellers, Internet service
providers, network service providers and intelligent computing device consumers
to provide additional functions to Windows-based intelligent computing devices,
such as printing and faxing capabilities, voice-over IP, remote device
management and wireless wide area least cost routing. Fourth, we license
standard manufacturing design of intelligent computing devices such as Webpads,
Web-phones, Pocket PCs, E-books and portable data tablets and bundle our
products and integration services for our customers.

     We intend to become a primary provider of products and services for
facilitating the rapid and cost-efficient development of intelligent computing
devices. Generally, an operating system provided by vendors in its original form
will not be readily compatible with the increasingly wide variety of
semiconductors and intelligent computing devices that are becoming available
and, therefore, will need to be adapted in order to function. We refer to this
process as "integration." The key elements of our strategy include building on
our expertise as a provider of Windows-based integration services, expanding our
strategic relationships with hardware and software vendors, maintaining and
expanding our relationship with Microsoft, developing additional software
applications, providing a comprehensive solution capability for rapid
development and deployment of intelligent computing devices and expanding our
international presence.

     We were incorporated in the State of Washington in July 1994. Our principal
executive offices are located at 3150 139th Avenue S.E., Suite 500, Bellevue,
Washington 98005, and our telephone number is (425) 519-5900. Our World Wide Web

                                  RISK FACTORS

     You should carefully consider the following risk factors and all other
information contained in this prospectus before purchasing our common stock.
Investing in our common stock involves a high degree of risk. Any of the
following risks could materially adversely affect our business, operating
results and financial condition and could result in a complete loss of your
investment.

UNANTICIPATED FLUCTUATIONS IN OUR QUARTERLY OPERATING RESULTS DUE TO FACTORS
SUCH AS ADVERSE CHANGES IN OUR RELATIONSHIP WITH MICROSOFT OR A DECLINE IN THE
MARKET FOR WINDOWS-BASED INTELLIGENT COMPUTING DEVICES COULD CAUSE OUR STOCK
PRICE TO DECLINE SIGNIFICANTLY.

     Our operating results have fluctuated in the past, and we expect that they
will continue to do so. We believe that period-to-period comparisons of our
operating results are not meaningful, and you should not rely on such
comparisons to predict our future performance. If our operating results fall
below the expectations of stock analysts and investors, the price of our common
stock may fall. Factors that may cause our quarterly operating results to
fluctuate include:

     - the failure or perceived failure of Windows CE, the operating system upon
       which demand for the majority of our products and services is dependent,
       to achieve widespread market acceptance;

     - the failure of the intelligent computing device market to develop;

     - adverse changes in our relationship with Microsoft, from which a
       substantial portion of our revenue is generated and on which we rely to
       continue to develop and promote Windows CE;

     - our inability to develop and market new and enhanced products and
       services on a timely basis;

     - unanticipated delays, or announcement of delays, by Microsoft of Windows
       product releases, which could cause us to delay our product introductions
       and adversely affect our customer relationships;

     - changes in demand for our products and services;

     - increased competition and changes in our pricing as a result of increased
       competitive pressure;

     - our ability to control our expenses, a large portion of which are
       relatively fixed and which are budgeted based on anticipated revenue
       trends, in the event that customer projects, particularly Microsoft
       projects, are delayed, curtailed or discontinued;

     - changes in the mix of our services and product revenue, which have
       different gross margins;

     - underestimates by us of the costs to be incurred in significant fixed-fee
       service projects; and

     - varying customer buying patterns which are often influenced by year-end
       budgetary pressures.

     In addition, our stock price may fluctuate due to conditions unrelated to
our operating performance, including general economic conditions in the software
industry and the market for technology stocks.

THE MAJORITY OF OUR REVENUE, INCLUDING 68% OF OUR TOTAL REVENUE FOR THE SIX
MONTHS ENDED JUNE 30, 2000, IS GENERATED FROM OUR RELATIONSHIP WITH MICROSOFT,
WHICH CAN BE MODIFIED OR TERMINATED BY MICROSOFT AT ANY TIME.

     For the year ended December 31, 1999 and for the six months ended June 30,
2000, approximately 85% and 68% of our revenue, respectively, was generated
under our master development and license agreement with Microsoft. The master
agreement, the current renewable term of which concludes in July 2001, includes
a number of project-specific work plans. We bill

                                        5
<PAGE>   9

Microsoft on a time-and-materials basis, although each project has a maximum
dollar cap. We expect the revenue generated from work plans with Microsoft will
continue to comprise the majority of our revenue for the next several years. We
presently have dedicated approximately 160 of our 370 engineers to these
projects. However, the master agreement and each of the individual work plans
may be terminated or modified by Microsoft at any time. In addition, there is no
guarantee that Microsoft will continue to enter into additional work plans with
us. In the past, Microsoft has modified the timing and scope of certain
projects, requesting that our engineers be moved from one project to another.
For example, in late 1997 Microsoft decided to contract with us to provide
Windows CE support services to semiconductor vendors with whom we had previously
contracted directly. As a result, from late 1997 through late 1998 our revenue
shifted from being generated by a variety of semiconductor vendors to being
generated primarily by Microsoft. We do not believe that we could replace the
Microsoft revenue in the short- or medium-term if existing work plans were
canceled or curtailed, and such cancellations or curtailments would
substantially reduce our revenue. Microsoft is a publicly traded company that
files financial reports and information with the Securities and Exchange
Commission. These reports are publicly available under Microsoft's Exchange Act
filing number, 000-14278.

IF THE MARKET FOR THE WINDOWS CE OPERATING SYSTEM FAILS TO DEVELOP FULLY OR
DEVELOPS MORE SLOWLY THAN WE EXPECT, OUR BUSINESS AND OPERATING RESULTS WILL BE
MATERIALLY HARMED.

     Windows CE is one of many operating systems developed for the intelligent
computing device market and the extent of its future acceptance is uncertain.
Because substantially all of our revenue for 1999 and the six months ended June
30, 2000 has been generated by software products and services dependent on the
Windows CE operating system, if the market for Windows CE fails to develop fully
or develops more slowly than we expect, our business and operating results will
be significantly harmed. Market acceptance of Windows CE will depend on many
factors, including:

     - Microsoft's development and support of the Windows CE market. As the
       developer and primary promoter of Windows CE, if Microsoft were to decide
       to discontinue or lessen its support of the Windows CE operating system,
       potential customers could select competing operating systems, which would
       reduce the demand for our Windows CE-based software products and
       services;

     - the ability of the Windows CE operating system to compete against
       existing and emerging operating systems for the intelligent computing
       device market including: VxWorks from WindRiver Systems Inc., pSOS from
       Integrated Systems, Inc., VRTX from Mentor Graphics Corporation, JavaOS
       from Sun Microsystems, Inc. and Linux. In particular, in the market for
       palm-size devices, Windows CE faces intense competition from PalmOS used
       on 3Com Corporation's Palm devices and to date has had limited success in
       this market. In the market for cellular phones, Windows CE faces intense
       competition from the EPOC operating system from Symbian, a joint venture
       among several of the largest manufacturers of cellular phones. Windows CE
       may be unsuccessful in capturing a significant share of these two
       segments of the intelligent computing device market, or in maintaining
       its market share in those other segments of the intelligent computing
       device market on which our business currently focuses, including the
       markets for Internet-enabled television set-top boxes, handheld
       industrial devices, consumer Internet appliances such as kiosk terminals
       and vehicle navigational devices, and Windows-based terminals;

     - the acceptance by original equipment manufacturers and consumers of the
       mix of features and functions offered by Windows CE; and

     - the willingness of software developers to continue to develop and expand
       the applications that run on Windows CE. To the extent that software
       developers write applications for competing

                                        6
<PAGE>   10

       operating systems that are more attractive to intelligent computing
       device end users than those available on Windows CE, potential purchasers
       could select competing operating systems over Windows CE.

IF THE MARKET FOR INTELLIGENT COMPUTING DEVICES FAILS TO DEVELOP FULLY OR
DEVELOPS MORE SLOWLY THAN WE EXPECT, OUR REVENUE WILL NOT GROW AS FAST AS
ANTICIPATED, IF AT ALL.

     The market for intelligent computing devices is emerging and the potential
size of this market and the timing of its development are not known. As a
result, our profit potential is uncertain and our revenue may not grow as fast
as we anticipate, if at all. We are dependent upon the broad acceptance by
businesses and consumers of a wide variety of Windows CE-based intelligent
computing devices, which will depend on many factors, including:

     - the development of content and applications for intelligent computing
       devices;

     - the willingness of large numbers of businesses and consumers to use
       devices such as handheld and palm-size PCs and handheld industrial data
       collectors to perform functions currently carried out manually or by
       traditional PCs, including inputting and sharing data, communicating
       among users and connecting to the Internet; and

     - the evolution of industry standards that facilitate the distribution of
       content over the Internet to these devices via wired and wireless
       telecommunications systems, satellite or cable.

IF MICROSOFT ADDS FEATURES TO ITS WINDOWS OPERATING SYSTEM THAT DIRECTLY COMPETE
WITH SOFTWARE PRODUCTS AND SERVICES WE PROVIDE, OUR REVENUE COULD BE REDUCED AND
OUR PROFIT MARGINS COULD SUFFER.

     As the developer of Windows, Microsoft could add features to its operating
system that directly compete with the software products and services we provide
to our customers. Such features could include, for example, faxing,
hardware-support packages and quality-assurance tools. The ability of our
customers or potential customers to obtain software products and services
directly from Microsoft that compete with our software products and services
could harm our business. Even if the standard features of future Microsoft
operating system software were more limited than our offerings, a significant
number of our customers and potential customers might elect to accept more
limited functionality in lieu of purchasing additional software. Moreover, the
resulting competitive pressures could lead to price reductions for our products
and reduce our profit margins.

IF WE DO NOT MAINTAIN OUR FAVORABLE RELATIONSHIP WITH MICROSOFT, WE WILL HAVE
DIFFICULTY MARKETING OUR SOFTWARE PRODUCTS AND SERVICES AND MAY NOT RECEIVE
DEVELOPER RELEASES OF WINDOWS CE, AND OUR REVENUE AND OPERATING MARGINS WILL
SUFFER.

     In the event that our relationship with Microsoft were to deteriorate, then
our efforts to market and sell our software products and services to original
equipment manufacturers could be adversely affected and our business would be
harmed. Microsoft has great influence over the development plans and buying
decisions of original equipment manufacturers utilizing Windows CE for
intelligent computing devices. Microsoft refers many of our original equipment
manufacturer customers to us. Moreover, Microsoft controls the marketing
campaigns related to its operating systems, including Windows CE. Microsoft's
marketing activities, including trade shows, direct mail campaigns and print
advertising, are important to the continued promotion and market acceptance of
Windows CE and, consequently, of our Windows CE-based software products and
services. We must maintain mutually successful relationships with Microsoft so
that we may continue to participate in joint marketing activities with
Microsoft, including participating in "partner pavilions" at trade shows and
listing our services on Microsoft's website, and to receive referrals from
Microsoft. In the event that we are unable to continue our joint marketing
efforts with Microsoft or fail to receive referrals from Microsoft, we would be
required to devote significant additional resources and incur additional

                                        7
<PAGE>   11

expenses to market our software products and services directly to potential
customers. In addition, we depend on receiving from Microsoft developer releases
of new versions of and upgrades to Windows CE and related Microsoft software in
order to timely develop and ship our products and provide services. If we are
unable to receive these developer releases, our revenue and operating margins
would suffer.

UNANTICIPATED DELAYS, OR ANNOUNCEMENT OF DELAYS, BY MICROSOFT OF WINDOWS CE
PRODUCT RELEASES COULD ADVERSELY AFFECT OUR SALES.

     Unanticipated delays, or announcement of delays, in Microsoft's delivery
schedule for new versions of its Windows CE operating system could cause us to
delay our product introductions and impede our ability to complete customer
projects on a timely basis. These delays or announcements by Microsoft could
also cause our customers to delay or cancel their project development activities
or product introductions. Any resulting delays in, or cancellations of, our
planned product introductions or in our ability to commence or complete customer
projects may adversely affect our revenue and could cause our quarterly
operating results to fluctuate. For example, in 1998 Microsoft delayed the
release of a version of its Windows CE Platform Builder, which delayed our
introduction of a complementary product for an original equipment manufacturer
customer.

OUR MARKET IS BECOMING INCREASINGLY COMPETITIVE, WHICH MAY RESULT IN PRICE
REDUCTIONS, LOWER GROSS MARGINS AND LOSS OF MARKET SHARE.

     The market for Windows CE-based software products and services is becoming
increasingly competitive. In addition, competition is intense for the business
of the limited number of original equipment manufacturer customers that are
capable of building and shipping large quantities of intelligent computing
devices. Increased competition may result in price reductions, lower gross
margins and loss of market share, which would harm our business. We face
competition from:

     - our current and potential customers' internal research and development
       departments that may seek to develop their own proprietary solutions;

     - large professional engineering services firms;

     - established intelligent computing device software and tools;

     - small- and medium-size engineering services; and

     - software and component distributors.

     As we develop new products, particularly products focused on specific
industries, we may begin competing with companies with whom we have not
previously competed. It is also possible that new competitors will enter the
market or that our competitors will form alliances, including alliances with
Microsoft, that may enable them to rapidly increase their market share.
Microsoft has not agreed to any exclusive arrangement with us nor has it agreed
not to compete with us. The barrier to entering the market as a provider of
Windows-based intelligent computing device software and services is low. In
addition, Microsoft has created a marketing program to encourage systems
integrators to work on Windows. These systems integrators are given the same
access by Microsoft to the Windows technology as we are. New competitors may
have lower overhead than us and may therefore be able to offer advantageous
pricing. We expect that competition will increase as other established and
emerging companies enter the Windows-based intelligent computing device market
and as new products and technologies are introduced.

IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, COMPETITORS
MAY BE ABLE TO USE OUR TECHNOLOGY OR TRADEMARKS, WHICH COULD WEAKEN OUR
COMPETITIVE POSITION, REDUCE OUR REVENUE AND INCREASE OUR COSTS.

     If we fail to adequately protect our intellectual property, our competitive
position could be weakened and our revenue adversely affected. We rely primarily
on a combination of patent, copyright, trade secret and trademark laws,
confidentiality procedures and contractual provisions to protect our
intellectual property. These laws and procedures provide only limited
protection. We have applied for four patents relating to our engineering work.
These patents, if issued, may not provide sufficiently broad protection or they
may not prove to be enforceable against alleged infringers. There can be no
assurance that any of our pending patents will be granted. Even if granted,
patents may be circumvented or challenged and, if challenged, may be
invalidated. Any patents obtained may provide limited or no competitive
advantage to us. It is also possible that another party could obtain patents
that block our use of some, or all, of our products and services. If that
occurred, we would need to obtain a license from the patent holder or design
around their patent. The patent holder may or may not choose to make a license
available to us at all or on acceptable terms. Similarly, it may not be possible
to design around such a blocking patent.

     In general, there can be no assurance that our efforts to protect our
intellectual property rights through patent, copyright, trade secret and
trademark laws will be effective to prevent misappropriation of our technology,
or to prevent the development and design by others of products or technologies
similar to or competitive with those developed by us. We frequently license the
source code of our products and the source code results of our services to
customers. There can be no assurance that customers with access to our source
code will comply with the license terms or that we will discover any violations
of the license terms or, in the event of discovery of violations, that we will
be able to successfully enforce the license terms and/or recover the economic
value lost from such violations. To license many of our software products, we
rely in part on "shrinkwrap" and "clickwrap" licenses that are not signed by the
end user and, therefore, may be unenforceable under the laws of certain
jurisdictions. As with other software products, our products are susceptible to
unauthorized copying and uses that may go undetected, and policing such
unauthorized use is difficult.

     A significant portion of our marks include the word "BSQUARE" or the
preface "b." Other companies use forms of "BSQUARE" or the preface "b" in their
marks alone or in combination with other words, and we cannot prevent all such
third-party uses. We license certain trademark rights to third parties. Such
licensees may not abide by compliance and quality control guidelines with
respect to such trademark rights and may take actions that would harm our
business.

     The computer software market is characterized by frequent and substantial
intellectual property litigation, which is often complex and expensive, and
involves a significant diversion of resources and uncertainty of outcome.
Litigation may be necessary in the future to enforce our intellectual property
or to defend against a claim of infringement or invalidity. Litigation could
result in substantial costs and the diversion of resources and could harm our
business and operating results.

THIRD PARTIES COULD ASSERT THAT OUR SOFTWARE PRODUCTS AND SERVICES INFRINGE
THEIR INTELLECTUAL PROPERTY RIGHTS, WHICH COULD EXPOSE US TO ADDITIONAL COSTS
AND LITIGATION.

     Third parties may claim that our current or future software products and
services infringe their proprietary rights, and these claims, regardless of
their merit, could increase our costs and harm our business. We have not
conducted patent searches to determine whether the technology used in our
products infringes patents held by third parties. In addition, it is difficult
to determine whether our software products and services infringe third-party
intellectual property rights, particularly in a rapidly evolving technological
environment in which there may be numerous patent applications pending,

                                        9
<PAGE>   13

many of which are confidential when filed, with regard to similar technologies.
If we were to discover that one of our software products violated a third
party's proprietary rights, we may not be able to obtain a license on
commercially reasonable terms, or at all, to continue offering that software
product. Moreover, any indemnification we obtain against claims that the
technology we license from third parties infringes the proprietary rights of
others may not always be available or may be limited in scope or amount. Even if
we receive broad third-party indemnification, these indemnitors may not have the
financial capability to indemnify us in the event of infringement. In addition,
in some circumstances we could be required to indemnify our customers for claims
made against them that are based on our solutions.

     There can be no assurance that infringement or invalidity claims related to
the software products and services we provide or arising from the incorporation
by us of third-party technology, and claims for indemnification from our
customers resulting from such claims, will not be asserted or prosecuted against
us. We expect that software product developers will be increasingly subject to
infringement claims, as the number of products and competitors in the software
industry grows and the functionality of products in different industry segments
overlaps. Such claims, even if not meritorious, could result in the expenditure
of significant financial and managerial resources in addition to potential
product redevelopment costs and delays.

IF WE DO NOT RESPOND ON A TIMELY BASIS TO TECHNOLOGICAL ADVANCES AND EVOLVING
INDUSTRY STANDARDS, OUR FUTURE PRODUCT SALES COULD BE NEGATIVELY IMPACTED.

     The market for Windows-based software products and services is new and
evolving. As a result, the life cycles of our products are difficult to
estimate. To be successful, we must continue to enhance our current product line
and develop new products. We have experienced delays in enhancements and new
product release dates in the past and may be unable to introduce enhancements or
new products successfully or in a timely manner in the future. Our business may
be harmed if we must delay releases of our products and product enhancements or
if these products and product enhancements fail to achieve market acceptance
when released. In addition, our customers may defer or forego purchases of our
products if we, Microsoft, our competitors or major hardware, systems or
software vendors introduce or announce new products or product enhancements.
Such deferrals or failures to purchase would decrease our revenue.

WE CANNOT ASSURE YOU THAT OUR REVENUE GROWTH RATE WILL NOT DECLINE OR THAT WE
WILL BE ABLE TO SUSTAIN OR INCREASE OUR PROFITABILITY.

     The rate of growth of our revenue over the prior year was 217% from 1996 to
1997, 63% from 1997 to 1998, and 60% from 1998 to 1999. The rate of growth of
our revenue over prior periods may continue to decline. We anticipate that our
expenses will increase substantially in the foreseeable future as we continue to
develop our technology and expand our product and service offerings. These
efforts may prove more expensive than we currently anticipate, and we may not
succeed in increasing our revenue sufficiently to offset these higher expenses.
If we fail to increase our revenue to keep pace with our expenses, we may
experience losses.

IF WE ARE UNABLE TO MANAGE OUR GROWTH OUR BUSINESS WILL SUFFER.

     Our rapid growth has placed, and is expected to continue to place, a
significant strain on our managerial, technical, operational and financial
resources. From August 1996 to June 2000, we grew from 21 employees to 459
employees, and we expect rapid growth to continue for the foreseeable future. To
manage our growth, we must implement additional management information systems,
further develop our operational, administrative and financial systems and
expand, train and manage our work force. We will also need to manage an
increasing number of complex relationships with customers, marketing partners
and other third parties. We cannot guarantee that our systems,

                                       10
<PAGE>   14

procedures or controls will be adequate to support our current or future
operations or that our management will be able to effectively manage our
expansion. Our failure to do so could seriously harm our ability to deliver
products and services in a timely fashion, fulfill existing customer commitments
and attract and retain new customers.

OUR INTERNATIONAL OPERATIONS EXPOSE US TO GREATER INTELLECTUAL PROPERTY,
MANAGEMENT, COLLECTIONS, REGULATORY AND OTHER RISKS.

     In late 1998 we opened offices in Munich, Germany and Tokyo, Japan. For the
year ended December 31, 1999 and for the six months ended June 30, 2000, less
than 1% of our total revenue was generated by our international offices. Our
international operations expose us to a number of risks, including the
following:

     - greater difficulty in protecting intellectual property due to less
       stringent foreign intellectual property laws and enforcement policies;

     - greater difficulty in managing foreign operations due to the lack of
       proximity between our home office and our foreign operations;

     - longer collection cycles in Japan than we typically experience in the
       U.S.;

     - unfavorable changes in regulatory practices and tariffs;

     - adverse changes in tax laws;

     - seasonal European sales declines in the summer months;

     - the impact of fluctuating exchange rates between the U.S. dollar and
       foreign currencies; and

     - general economic and political conditions in Asian and European markets.

     These risks could have a material adverse effect on the financial and
managerial resources required to operate our foreign offices, as well as on our
future international revenue, which could harm our business.

RECENT AND FUTURE ACQUISITIONS COULD PROVE DIFFICULT TO INTEGRATE, DISRUPT OUR
BUSINESS, DILUTE SHAREHOLDER VALUE AND ADVERSELY AFFECT OUR OPERATING RESULTS.

     We recently acquired BlueWater Systems, Inc. and Mainbrace Corporation, and
we may acquire or make investments in complementary companies, services and
technologies in the future. If we fail to properly evaluate, execute and
integrate acquisitions and investments, including these recent acquisitions, our
business and prospects may be seriously harmed. To successfully complete an
acquisition, we must properly evaluate the technology, accurately forecast the
financial impact of the transaction, including accounting charges and
transaction expenses, integrate and retain personnel, combine potentially
different corporate cultures and effectively integrate products and research and
development, sales, marketing and support operations. If we fail to do any of
these, we may suffer losses and impair relationships with our employees,
customers and strategic partners, and our management may be distracted from our
day-to-day operations. We also may be unable to maintain uniform standards,
controls, procedures and policies, and significant demands may be placed on our
management and our operations, information services and financial, legal and
marketing resources. Finally, acquired businesses sometimes result in unexpected
liabilities and contingencies which could be significant. In addition,
acquisitions using debt or equity securities dilute the ownership of existing
shareholders, which could affect the market price of our stock.

                                       11
<PAGE>   15

IF WE ARE UNABLE TO LICENSE KEY SOFTWARE FROM THIRD PARTIES OUR BUSINESS COULD
BE HARMED.

     We often integrate third-party software with our internally developed
software to provide software products and services for our original equipment
manufacturer customers. If our relationships with our third-party vendors were
to deteriorate, we might be unable to obtain licenses on commercially reasonable
terms, if at all, for newer versions of their software required to maintain
compatibility. In the event that we are unable to obtain additional licenses, we
would be required to develop this technology internally, which could delay or
limit our ability to introduce enhancements or new products or to continue to
sell existing products.

OUR SOFTWARE PRODUCTS OR THE THIRD-PARTY HARDWARE OR SOFTWARE INTEGRATED WITH
OUR SOFTWARE PRODUCTS AND SERVICES MAY SUFFER FROM DEFECTS OR ERRORS THAT COULD
IMPAIR OUR ABILITY TO SELL OUR SOFTWARE PRODUCTS AND SERVICES.

     Software and hardware components as complex as those needed for intelligent
computing devices frequently contain errors or defects, especially when first
introduced or when new versions are released. We have had to delay commercial
release of certain versions of our software products until software problems
were corrected, and in some cases have provided product enhancements to correct
errors in released products. Some of our contracts require us to repair or
replace products that fail to work. To the extent that we repair or replace
products our expenses may increase, resulting in a decline in our gross margins.
In addition, it is possible that by the time defects are fixed the market
opportunity may have been missed which may result in lost revenue. Moreover,
errors that are discovered after commercial release could result in loss of
revenue or delay in market acceptance, diversion of development resources,
damage to our reputation or increased service and warranty costs, all of which
could harm our business.

WE MAY BE SUBJECT TO PRODUCT LIABILITY CLAIMS THAT COULD RESULT IN SIGNIFICANT
COSTS.

     Our license agreements with our customers typically contain provisions
designed to limit our exposure to potential product liability claims. It is
possible, however, that these provisions may be ineffective under the laws of
certain jurisdictions. Although we have not experienced any product liability
claims to date, the sale and support of our software products and services
entail the risk of such claims and we may be subject to such claims in the
future. A product liability claim brought against us, whether successful or not,
could harm our business and operating results.

THE LENGTHY SALES CYCLE OF OUR PRODUCTS AND SERVICES MAKES OUR REVENUE
SUSCEPTIBLE TO FLUCTUATIONS.

     Our sales cycle is typically three to six months because the expense and
complexity of our products and services generally require a lengthy customer
approval process, and may be subject to a number of significant risks over which
we have little or no control, including:

     - customers' budgetary constraints and internal acceptance review
       procedures;

     - the timing of budget cycles; and

     - the timing of customers' competitive evaluation processes.

     In addition, to successfully sell our products and services, we frequently
must educate our potential customers about the full benefits of our products and
services, which can require significant time. If our sales cycle lengthens
unexpectedly, it could adversely affect the timing of our revenue which could
cause our quarterly results to fluctuate.

                                       12
<PAGE>   16

THE VOLATILITY OF THE STOCK MARKETS COULD ADVERSELY AFFECT OUR STOCK PRICE.

     Stock markets are subject to significant price and volume fluctuations
which may be unrelated to the operating performance of particular companies, and
the market price of our common stock may therefore frequently change. The market
price of our common stock could also fluctuate substantially due to a variety of
other factors, including quarterly fluctuations in our results of operations,
our ability to meet analysts' expectations, adverse circumstances affecting the
introduction and market acceptance of new products and services offered by us,
announcements of new products and services by competitors, changes in the
information technology environment, changes in earnings estimates by analysts,
changes in accounting principles, sales of our common stock by existing holders
and the loss of key personnel.

A SMALL NUMBER OF OUR EXISTING SHAREHOLDERS CAN EXERT CONTROL OVER US.

     Our executive officers, directors and principal shareholders holding more
than 5% of our common stock together control a majority of our outstanding
common stock. As a result, these shareholders, if they act together, could
control our management and affairs of the company and all matters requiring
shareholder approval, including the election of directors and approval of
significant corporate transactions. This concentration of ownership may have the
effect of delaying or preventing a change in control of us and might affect the
market price of our common stock.

IT MIGHT BE DIFFICULT FOR A THIRD PARTY TO ACQUIRE US EVEN IF DOING SO WOULD BE
BENEFICIAL TO OUR SHAREHOLDERS.

     Certain provisions of our amended and restated articles of incorporation,
bylaws and Washington law may discourage, delay or prevent a change in the
control of us or a change in our management even if doing so would be beneficial
to our shareholders. Our board of directors has the authority under our amended
and restated articles of incorporation to issue preferred stock with rights
superior to the rights of the holders of common stock. As a result, preferred
stock could be issued quickly and easily with terms calculated to delay or
prevent a change in control of our company or make removal of our management
more difficult. In addition, as of this year's annual meeting of shareholders,
our board of directors was divided into three classes. The directors in each
class will serve for three-year terms, one class being elected each year by our
shareholders. This system of electing and removing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to
obtain control of our company because it generally makes it more difficult for
shareholders to replace a majority of our directors.

     In addition, Chapter 19 of the Washington Business Corporation Act
generally prohibits a "target corporation" from engaging in certain significant
business transactions with a defined "acquiring person" for a period of five
years after the acquisition, unless the transaction or acquisition of shares is
approved by a majority of the members of the target corporation's board of
directors prior to the time of acquisition. This provision may have the effect
of delaying, deterring or preventing a change in control of our company. The
existence of these antitakeover provisions could limit the price that investors
might be willing to pay in the future for shares of our common stock.

                           FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934 based on current expectations, estimates and projections
about our industry and our management's beliefs and assumptions. When used in
this prospectus and elsewhere, the words "believes," "plans," "estimates,"
"intends," "anticipates," "seeks" and "expects" and similar expressions are
intended to identify forward-looking statements. These forward-looking
statements include, but are not limited to, statements about our plans,
objectives, expectations and intentions and other statements that are not
historical facts. These forward-looking statements are not guarantees of future
performance and are subject to certain risks and uncertainties that are
difficult to predict. Accordingly, actual results may differ materially from
those anticipated or expressed in such statements. Particular attention should
be paid to the cautionary statements contained in this prospectus under "Risk
Factors" involving potential fluctuations in our quarterly operating results,
our reliance on Microsoft, uncertainty about the Windows CE market,
unpredictability of future revenue, the intensely competitive nature of our
industry, our limited operating history, management of growth, the integration
of acquisitions and our reliance on third parties, manufacturers, distributors
and suppliers. Readers are cautioned not to place undue reliance on the
forward-looking statements, which speak only as of the date made. Except as
required by law, we undertake no obligation to update any forward-looking
statement, whether as a result of new information, future events or otherwise.
Readers, however, should carefully review the factors set forth in this and
other reports or documents that we file from time to time with the Securities
and Exchange Commission.

                                USE OF PROCEEDS

     We will not receive any proceeds from the sales of common stock by the
selling shareholders pursuant to this prospectus. We will bear all expenses of
registration incurred in connection with this offering, but the selling
shareholders will bear all selling and other expenses they incur.

                                DIVIDEND POLICY

     We have never paid cash dividends on our common stock other than the
distribution of S corporation earnings prior to October 1997, when we converted
to a C corporation. We currently intend to retain any future earnings to fund
the development and growth of our business. Therefore, we do not currently
anticipate paying any cash dividends in the foreseeable future. In addition, the
terms of our current credit facility prohibit us from paying dividends without
our lender's consent.

                                    DILUTION

     The sales of common stock by the selling shareholders as described in this
prospectus do not dilute the shares of common stock because the shares of common
stock sold under this prospectus are already issued and outstanding.

                              PLAN OF DISTRIBUTION

     We are registering 635,486 shares of our common stock on behalf of certain
selling shareholders. All of the shares were issued by us in connection with our
acquisition of BlueWater Systems and Mainbrace Corporation. We will receive no
proceeds from this offering. The selling shareholders named in this prospectus
or pledgees, donees, transferees or other successors-in-interest selling shares
received from a named selling shareholder as a gift, partnership distribution or
other non-sale-related transfer after the date of this prospectus may sell some
or all of the shares from time to time. REGISTRATION OF THE SHARES DOES NOT
MEAN, HOWEVER, THAT THE SHARES NECESSARILY WILL BE OFFERED OR SOLD. The selling
shareholders will act independently of us in making decisions with respect to
the timing, manner and size of each sale. The sales may be made on one or more
exchanges or in the over-the-counter market or otherwise, at prices and at terms
then prevailing or at prices related to the then current market price, or in
negotiated transactions. The selling shareholders may effect such transactions
by selling the shares to or through broker-dealers. The shares may be sold by
one or more of, or a combination of, the following:

     - a block trade in which the broker-dealer so engaged will attempt to sell
       the shares as agent but may position and resell a portion of the block as
       principal to facilitate the transaction,

     - purchases by a broker-dealer as principal and resale by such
       broker-dealer for its account pursuant to this prospectus,

     - an exchange distribution in accordance with the rules of such exchange,

     - ordinary brokerage transactions and transactions in which the broker
       solicits purchasers, and

     - in privately negotiated transactions.

     To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. In effecting sales,
broker-dealers engaged by the selling shareholders may arrange for other
broker-dealers to participate in the resales.

     The selling shareholders may enter into hedging transactions with
broker-dealers in connection with distributions of the shares or otherwise. In
such transactions, broker-dealers may engage in short sales of the shares in the
course of hedging the positions they assume with selling shareholders. The
selling shareholders also may sell shares short and redeliver the shares to
close out such short positions. The selling shareholders may enter into option
or other transactions with broker-dealers which require the delivery to the
broker-dealer of the shares. The broker-dealer may then resell or otherwise
transfer such shares pursuant to this prospectus. The selling shareholders also
may loan or pledge the shares to a broker-dealer. The broker-dealer may sell the
shares so loaned, or upon a default the broker-dealer may sell the pledged
shares pursuant to this prospectus.

     Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from selling shareholders. Broker-dealers
or agents may also receive compensation from the purchasers of the shares for
whom they act as agents or to whom they sell as principals, or both.
Compensation as to a particular broker-dealer might be in excess of customary
commissions and will be in amounts to be negotiated in connection with the sale.
Broker-dealers or agents and any other participating broker-dealers or the
selling shareholders may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act of 1933 in connection with sales of the
shares. Accordingly, any such commission, discount or concession received by
them and any profit on the resale of the shares purchased by them may be deemed
to be underwriting discounts or commissions under the Securities Act. Because
selling shareholders may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act, the selling shareholders will be subject to
the prospectus delivery requirements of the Securities Act. In addition, any
securities covered by this prospectus which qualify for sale pursuant to Rule
144 promulgated under the Securities Act may be

                                       16
<PAGE>   20

sold under Rule 144 rather than pursuant to this prospectus. To our knowledge,
the selling shareholders have not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of their
securities.

     The shares will be sold only through registered or licensed brokers or
dealers if required under applicable state securities laws. In addition, in
certain states the shares may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with.

     Under applicable rules and regulations under the Securities and Exchange
Act of 1934, any person engaged in the distribution of the shares may not
simultaneously engage in market making activities with respect to our common
stock for a period of two business days prior to the commencement of such
distribution. In addition, each selling shareholder will be subject to
applicable provisions of the Exchange Act and the associated rules and
regulations under the Exchange Act, including Regulation M, which provisions may
limit the timing of purchases and sales of shares of our common stock by the
selling shareholders. We will make copies of this prospectus available to the
selling shareholders and we have informed them of the need for delivery of
copies of this prospectus to purchasers at or prior to the time of any sale of
the shares.

     We will file a supplement to this prospectus, if required, pursuant to Rule
424(b) under the Securities Act upon being notified by a selling shareholder
that any material arrangement has been entered into with a broker-dealer for the
sale of shares through a block trade, special offering, exchange distribution or
secondary distribution or a purchase by a broker or dealer. Such supplement will
disclose:

     - the name of each such selling shareholder and of the participating
       broker-dealer(s),

     - the number of shares involved,

     - the price at which such shares were sold,

     - the commissions paid or discounts or concessions allowed to such
       broker-dealer(s), where applicable,

     - that such broker-dealer(s) did not conduct any investigation to verify
       the information set out or incorporated by reference in this prospectus,
       and

     - other facts material to the transaction.

     We will bear all costs, expenses and fees in connection with the
registration of the shares. The selling shareholders will bear all commissions
and discounts, if any, attributable to the sales of the shares. The selling
shareholders may agree to indemnify any broker-dealer or agent that participates
in transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act.

                              SELLING SHAREHOLDERS

     The following table sets forth the number of shares owned by each of the
selling shareholders. None of the selling shareholders has had a material
relationship with us within the past three years other than as a result of the
ownership of the shares reflected below or other of our securities or as a
result of their employment with us or our subsidiaries. We cannot give an
estimate as to the amount of shares that will be held by the selling
shareholders after completion of this offering because the selling shareholders
may offer all or some of the shares and because, to our knowledge, there
currently are no agreements, arrangements or understandings with respect to the
sale of any of the shares. The shares offered by this prospectus may be offered
from time to time by the selling shareholders named below.

                      SELECTED CONSOLIDATED FINANCIAL DATA

     The following selected consolidated financial data as of and for the years
ended December 31, 1996, 1997, 1998 and 1999 are derived from our consolidated
financial statements included elsewhere in this prospectus, which have been
audited by Arthur Andersen LLP, independent public accountants. The consolidated
financial data as of and for the period ended December 31, 1995 are derived from
unaudited financial statements. The consolidated financial data as of and for
the six months ended June 30, 1999 and 2000 are derived from unaudited financial
statements included elsewhere in this prospectus. Additionally, on January 5,
2000 we acquired BlueWater Systems, Inc. in a transaction accounted for as a
pooling of interests. All of our financial data presented in the consolidated
financial statements and results of operations have been restated to include the
historical financial information of BlueWater Systems, Inc. as if it had always
been a part of BSQUARE. We have prepared this unaudited information on the same
basis as the audited consolidated financial statements and have included all
adjustments, consisting of only normal recurring adjustments, that we consider
necessary for a fair presentation of our financial position and operating
results. When you read this selected consolidated financial data, it is
important that you also read the historical consolidated financial statements
and related notes included in this prospectus, as well as the section of this
prospectus entitled "Management's Discussion and Analysis of Financial Condition
and Results of Operations." Our historical results are not necessarily
indicative of our future results.

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

     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations should be read in conjunction with our consolidated
financial statements and related notes included elsewhere in this prospectus.

OVERVIEW

     We are a leading provider of software solutions that enable the development
and proliferation of a wide variety of intelligent computing devices based on
the Microsoft Windows-based operating systems. We work with semiconductor
vendors and original equipment manufacturers to provide software products and
engineering services for the development of intelligent computing devices.

     We enable the rapid and low-cost deployment of intelligent computing
devices by providing a variety of software products and services for the
development, integration and deployment of Windows-powered operating systems
with industry-specific applications. We also develop software applications that
are licensed to end users to provide intelligent computing devices with
additional functionality. Our products and services are marketed and supported
on a worldwide basis through a direct sales force augmented by distributors.

     Our revenue totaled $15.9 million in 1997, $25.9 million in 1998, $41.4
million in 1999 and $29.0 million for the six months ended June 30, 2000. We
generated net income of $4.0 million in 1997, $2.3 million in 1998, $1.7 million
in 1999, and a loss of $1.5 million for the six months ended June 30, 2000.

     To date, we have derived the majority of our revenue from the provision of
services to Microsoft, semiconductor vendors and original equipment
manufacturers. We also generate product revenue from software sales and royalty
licenses. We perform our services under both time-and-materials contracts and
fixed-fee contracts. We also receive a small portion of service revenue from the
provision of contract support services upon the purchase of our software
products. We sell our packaged software products through standard retail
channels, our direct sales force and through indirect channels, such as
resellers. In addition, we receive royalty payments from original equipment
manufacturers related to the bundling of our software on their intelligent
computing devices and, more recently, from the license to them of software
products contained in our intelligent computing device integration tool kits.

     On January 5, 2000, we acquired BlueWater Systems, Inc., a privately held
designer of software development tools for the creation of Windows-based
intelligent computing devices. The transaction was accounted for using the
pooling-of-interests method of accounting. All of our financial data presented
in the consolidated financial statements and results of operations have been
restated to include the historical financial information of BlueWater Systems,
Inc. as if it had always been a part of BSQUARE.

     On May 24, 2000, we acquired Mainbrace Corporation in a transaction
accounted for as a purchase. Mainbrace Corporation, located in Sunnyvale,
California, is an intellectual property-licensing and enabling software firm
delivering products and services to high-volume market segments including
set-top boxes, web-enabled phones, wireless thin clients and electronic book
readers. The financial data presented in the consolidated financial statements
include the results of operations of Mainbrace Corporation beginning on May 25,
2000.

MICROSOFT MASTER DEVELOPMENT AND LICENSE AGREEMENT

     In 1997, 1998, 1999 and for the six months ended June 30, 2000,
approximately 35%, 75%, 85% and 68% of our revenue, respectively, was generated
under our master development and license

                                       20
<PAGE>   24

agreement with Microsoft. The master agreement, the current renewable term of
which concludes in July 2001, includes a number of project-specific work plans.
We bill Microsoft on a time-and-materials basis, although each project has a
maximum dollar cap, and recognize revenue generated under the master agreement
as the services are rendered. The master agreement and each of the individual
work plans may be modified or terminated by Microsoft at any time. While we
anticipate that our relationship with Microsoft will remain strong, we are
unable to predict the magnitude and number of future projects for Microsoft.

</TABLE>

COMPARISON OF SIX MONTHS ENDED JUNE 30, 1999 AND 2000

Revenue

     Revenue consists of service and product revenue, which includes software
license fees and royalties. Total revenue for the six-month period ended June
30, 2000 increased 51% to $29.0 million, from $19.3 million for the same period
in 1999. The increase in total revenue resulted from an increase in number and
scope of professional service projects as well as an increase in product
revenue. For the six-month periods, Microsoft accounted for 68% and 85% of
revenue for 2000 and 1999, respectively. The decrease in the percentage of
revenue derived from Microsoft was due to the

                                       21
<PAGE>   25

signing of silicon vendors under the Porting Partner Agreement and the growth in
services provided to non-tools customers.

     Revenue outside of the U.S. was $3.5 million and $271,000 for the six
months ended June 30, 2000 and 1999, respectively. The increase in international
revenue was due to an increase in both services and products sold to
international OEM customers.

     Service revenue. Service revenue was $26.5 million for the six months ended
June 30, 2000 compared to $18.1 million for the same period in 1999, a 46%
increase. The increase was due to a continued increase in the number and size of
consulting service projects.

     Product revenue. For the six-month period ended June 30, 2000, product
revenue was $2.5 million compared to $1.2 million for the same period in 1999, a
114% increase. The increase in product revenue was due to increases in sales of
the CE Validator quality assurance test suite, sale of strategic alliance
third-party products and royalty income. As a percentage of total revenue,
product revenue increased to 9% of total revenue for the six months ended June
30, 2000 compared to 6% for the same period in 1999.

Cost of Revenue

     Cost of service revenue. Cost of service revenue consists primarily of
salaries and benefits for software developers and quality assurance personnel,
plus an allocation of facilities and depreciation costs. For the six-month
period ended June 30, 2000, cost of service revenue was $13.1 million compared
to $8.7 million for the same period in 1999, a 50% increase. Cost of service
revenue increased in absolute dollars due to hiring and training of additional
employees to support an increased number of consulting projects. At June 30,
2000 and 1999, we had approximately 284 and 209 employees, respectively, engaged
in engineering consulting. Cost of service revenue as a percentage of related
service revenue was 49% for the six-month period ended June 30, 2000 compared to
48% for the same period in 1999. The increase in cost of service revenue as a
percentage of the related service revenue in 2000 was primarily the result of an
increase in software engineering compensation due to competitive employee
recruiting and retention pressures in the greater-Seattle area.

     Cost of product revenue. Cost of product revenue consists of license fees
and royalties for third-party software, product media, product duplication and
manuals. For the six-month period ended June 30, 2000, cost of product revenue
was $666,000 compared to $139,000 for the same period in 1999, a 379% increase.
As a percentage of related product revenue, cost of product revenue was 27% for
the six months ended June 30, 2000 compared to 12% for the same period in 1999.
The increase in cost of product revenue as a percentage of related product
revenue relates to an increase in sales of third-party products in the first six
months of 2000 over the same period in 1999.

Operating Expenses

     Research and development. Research and development expenses consist
primarily of salaries and benefits for software developers, quality assurance
personnel and program managers, plus an allocation of our facilities and
depreciation costs. For the six-month period ended June 30, 2000, research and
development costs were $4.2 million, compared to $3.3 million for the same
period in 1999, a 29% increase. This increase was due to an increase in the
number of software developers and quality assurance personnel hired to expand
our product offerings and to support development and testing activities.
Research and development expenses represented 15% and 17% of our total revenue
for the six months ended June 30, 2000 and 1999, respectively. The decrease in
research and development expenses as a percentage of total revenue in 2000
reflects the more rapid increase of our revenue compared to the growth in
research and development expenses. We anticipate that research and

                                       22
<PAGE>   26

development expenses will continue to increase in absolute dollars in future
periods as we continue to expand our market position.

     Selling, general and administrative. For the six-month period ended June
30, 2000, selling, general and administrative expenses were $7.9 million
compared to $5.3 million for the same period in 1999, a 48% increase. This
increase resulted primarily from our investment in sales and marketing
infrastructure, both domestically and internationally, which included
significant personnel-related expenses, travel expenses and related facility and
equipment costs, corporate advertising, as well as annual reporting and other
costs associated with having become a public company. For the six-month periods
ended June 30, 2000 and 1999, these expenses represented 28% and 27% of total
revenue, respectively. We anticipate that selling, general and administrative
expenses will continue to increase in absolute dollars in future periods as we
expand our sales and marketing staff both internationally and domestically.

     Acquisition of in-process research and development and amortization of
intangible assets. On May 24, 2000, we acquired Mainbrace Corporation, an
intellectual property-licensing and enabling software firm delivering product
solutions including set-top boxes, web-enabled phones, wireless thin clients,
and electronic book readers to high-volume market segments. The acquisition was
accounted for using the purchase method of accounting, and, accordingly, the
results of Mainbrace's operations are included in our consolidated financial
statements since the date of acquisition.

     The purchase price was allocated to the fair value of the acquired assets
and assumed liabilities based on their fair market values at the date of the
acquisition. Of the total purchase price, we allocated $4.1 million to acquired
in-process research and development, $16.9 million to goodwill and other
intangible assets and $1.0 million to working capital and tangible assets. The
amount allocated to in-process research and development was determined by an
independent valuation and has been recorded as a charge to expense because its
technological feasibility had not been established and it had no alternative
future use at the date of acquisition. Goodwill and other intangible assets will
be amortized over their estimated future lives of two to seven years. We
anticipate that future amortization of intangible assets will approximate $1.1
million per quarter.

     Amortization of deferred stock option compensation. We recorded
amortization of deferred stock option compensation of $318,000 for the six
months ended June 30, 2000 and $294,000 for the same period in 1999. These
charges resulted from stock option grants at prices below the deemed fair market
value of our common stock when we were a private company. Deferred stock option
compensation is amortized over the vesting periods of the options.

Interest Income (Expense), Net

     Interest income, net consists primarily of earnings on our cash, cash
equivalents and short-term investment balances offset by interest expense
associated with debt obligations. For the six-month periods ended June 30, 2000
and 1999, interest income, net was $1.8 million and $133,000, respectively. The
increase resulted from higher average cash, cash equivalent and short-term
investment balances.

     In January 2000, we acquired BlueWater Systems, Inc. in a transaction
accounted for as a pooling of interests. In connection with the acquisition, we
incurred $620,000 of acquisition-related costs ($515,000 after taxes, or $0.01
per diluted share) which were charged to operations during the six months ended
June 30, 2000.

Income Taxes

     Our provision for federal, state and international income taxes was $1.0
million for the six months ended June 30, 2000, compared to $712,000 for the six
months ended June 30, 1999, yielding

                                       23
<PAGE>   27

an effective rate of (229)% during that period in 2000 and 45% during that
period in 1999. The effective rate in 2000 was positively affected by the tax
benefit of interest income earned on tax-exempt and tax-advantaged municipal
securities held in our short-term investment portfolio, and was negatively
affected by the non-deductibility of in-process research and development and
amortization of intangible assets. The effective tax rate in 1999 was negatively
affected by the non-deductibility of the losses generated by international
operations.

COMPARISON OF YEARS ENDED DECEMBER 31, 1997, 1998 AND 1999

Revenue

     Total revenue increased 63% from $15.9 million in 1997 to $25.9 million in
1998, and an additional 60% to $41.4 million in 1999. Microsoft accounted for
35%, 75% and 85% of total revenue in 1997, 1998 and 1999, respectively. Revenue
outside of North America totaled $4.3 million in 1997, $1.2 million in 1998 and
$1.5 million in 1999. The decrease in international revenue from 1997 to 1998
correlates with the corresponding increase in Microsoft revenue resulting from
the shift from working directly with semiconductor vendors to working with
Microsoft for the benefit of those customers during this period. The increase in
international revenue from 1998 to 1999 is the result of an increase in the
number and size of software integration service and product contracts with OEMs.

     Service revenue. Service revenue increased 64% from $14.5 million in 1997
to $23.7 million in 1998, and an additional 64% to $38.8 million in 1999. The
increases in service revenue for all periods were due to the increasing number
and size of service projects. As a percentage of total revenue, service revenue
did not change materially between 1997 and 1998 and increased between 1998 and
1999 due to an increase in the growth of the number and size of software
integration contracts.

     Product revenue. Product revenue increased 53% from $1.5 million in 1997 to
$2.2 million in 1998, and an additional 15% to $2.6 million in 1999. The
increases in product revenue from 1997 to 1999 resulted from the expansion of
product offerings from software applications for handheld PCs to intelligent
computing device integration tool kits and CE Validator quality assurance test
suites. As a percentage of total revenue, product revenue did not change
materially between 1997 and 1998 and decreased between 1998 and 1999 due to an
increase in service revenue as a result of the growth of the number and size of
software integration contracts.

Cost of Revenue

     Cost of service revenue. Cost of service revenue increased 98% from $5.6
million in 1997 to $11.0 million in 1998, and an additional 72% to $19.0 million
in 1999. These increases resulted from the hiring and training of additional
employees to support our growing customer base. At December 31, 1997, 1998 and
1999, we had 94, 160 and 231 employees, respectively, engaged in engineering
consulting. Cost of service revenue as a percentage of related service revenue
was 39% in 1997, 47% in 1998 and 49% in 1999. The increases in cost of service
revenue as a percentage of related service revenue reflect higher personnel
costs related to the competitive employee recruiting and retention pressures in
the greater-Seattle area, as well as higher facilities and depreciation costs
associated with expansion.

     Cost of product revenue. Cost of product revenue increased 31% from
$249,000 in 1997 to $326,000 in 1998, and an additional 62% to $529,000 in 1999.
Cost of product revenue as a percentage of related product revenue was 17% in
1997, 15% in 1998 and 20% in 1999. The decrease in cost of product revenue as a
percent of related product revenue from 1997 to 1998 relates to a change in mix
from pre-package applications sales in 1997 to royalty revenue earned from the
bundling of software applications in 1998. The increase in cost of product
revenue as a percentage of related product revenue from 1998 to 1999 relates to
a change in mix of product sales from royalties

                                       24
<PAGE>   28

received from original equipment manufacturers for licenses of applications in
1998 to a higher proportion of pre-packaged BSQUARE and third-party applications
in 1999.

Operating Expenses

     Research and development. Research and development expenses increased 113%
from $2.1 million in 1997 to $4.4 million in 1998, and an additional 69% to $7.5
million in 1999. These increases relate primarily to the increase in the number
of software developers and quality assurance personnel hired to expand our
product offerings and to support our product development and testing activities.
Research and development expenses represented 13% of our total revenue in 1997,
17% in 1998 and 18% in 1999. The increases in research and development expenses
as a percentage of total revenue primarily reflect the more rapid investment in
our research and development activities compared to the growth of our revenue
during these periods. We anticipate that research and development expenses will
continue to increase in absolute dollars in future periods.

     Selling, general and administrative. Selling, general and administrative
expenses increased 119% from $3.1 million in 1997 to $6.8 million in 1998, and
an additional 75% to $11.9 million in 1999. These increases resulted primarily
from our investment in finance, executive, administration, sales and marketing
infrastructure, both domestically and internationally, which included
significant personnel-related expenses, travel expenses and related facility and
equipment costs, as well as increased marketing activities, including trade
shows, public relations and other promotional expenses. Selling, general and
administrative expenses represented 19% of our total revenue in 1997, 26% in
1998 and 29% in 1999. The increases in selling, general and administrative
expenses as a percentage of total revenue primarily reflect the more rapid
investment in our administrative and sales and marketing infrastructure compared
to the growth of our revenue during these periods. During the fourth quarter of
1998, we opened sales offices in Munich, Germany and Tokyo, Japan. To establish
and operate these offices, we invested $502,000 in 1998 and $1.9 million in
1999, which are included in the expense amounts above. We anticipate that
selling, general and administrative expenses will continue to increase in
absolute dollars in future periods as we expand our sales and marketing staff
both internationally and domestically, as well as incur expenses associated with
being a public company.

     Amortization of deferred stock option compensation. We recorded
amortization of deferred stock option compensation of $81,000 in 1997, $171,000
in 1998 and $583,000 in 1999, resulting from stock option grants at prices below
the deemed fair market value of our common stock when we were a private company.

Interest income (expense), net

     Interest income (expense), net was $(8,000) in 1997, $326,000 in 1998 and
$926,000 in 1999. These increases resulted from higher average cash, cash
equivalent and short-term investment balances over the prior year.

Income taxes

     Our provision for federal, state and international income taxes was
$804,000 for 1997, $1.2 million for 1998 and $1.1 million 1999, yielding an
effective rate of 16.7%, 33.6% and 39.4% in 1997, 1998 and 1999, respectively.
We were taxed as a subchapter S corporation until October 15, 1997, when our
shareholders elected to convert to a C corporation. Accordingly, taxes on our
income were the responsibility of the shareholders until the conversion. The
increase in the effective tax rate in 1999 over 1998 was due primarily to the
effect of the non-deductibility of losses from our international operations.

                                       25

                        LIQUIDITY AND CAPITAL RESOURCES

     Since our inception through December 1999, we financed our operations and
capital expenditures primarily through cash flow from operations. As of June 30,
2000, we had $79.8 million of cash, cash equivalents and short-term investments.
This represents a decrease of $3.2 million over December 31, 1999. In October
1999, we completed an initial public offering of 4,000,000 shares of common
stock and raised $54.4 million, net of offering costs. In addition, in September
1999, we sold 1,518,378 shares of our common stock to Vulcan Ventures for
approximately $18.7 million. In January 1998, we issued mandatorily redeemable
convertible preferred stock from which we received net proceeds of approximately
$14.3 million. Concurrent with this transaction, we repurchased 3,333,333 shares
of our common stock for an aggregate of $6.0 million. To a lesser extent, we
have financed software system purchases through traditional financing
arrangements. Our working capital at June 30, 2000 was $73.0 million compared to
$81.7 million at December 31, 1999.

     Our operating activities resulted in net cash inflows of $4.6 million in
1997, $129,000 in 1998, $10.0 million in 1999 and $11.1 million for the six
months ended June 30, 2000. Cash provided by operating activities resulted
primarily from income from operations (excluding acquired in-process research
and development and amortization of intangible assets during the six months
ended June 30, 2000) and increases in deferred revenue, accounts payable and
accrued liabilities, partially offset by increases in accounts receivable.

     Investing activities used cash of $1.5 million in 1997, $3.7 million in
1998, $32.8 million in 1999 and $11.9 million for the six months ended June 30,
2000. Investing activities for 1997 and 1998 were primarily purchases of capital
equipment. Investing activities in 1999 included $25.8 million in purchases of
short-term investments and $7.0 million in purchases of capital equipment.
Investing activities in the six months ended June 30, 2000 included $14.3
million in net cash used in connection with the acquisition of Mainbrace
Corporation, $1.3 million of cash used for the purchase of an investment and
$597,000 of capital equipment purchases.

     Financing activities used $775,000 in 1997, primarily for shareholder draws
and repayment of long-term obligations. Financing activities generated $6.5
million in 1998, primarily through the issuance of mandatorily convertible
preferred stock, partially offset by repayment of shareholder loans and the $6.0
million repurchase of shares of common stock. Financing activities in 1999
generated $72.9 million due to the net proceeds from the initial public offering
and from the sale of common stock to Vulcan Ventures. Financing activities
generated $1.9 million for the six months ended June 30, 2000 due to proceeds
from the issuance of shares under our employee stock purchase plan, the exercise
of stock options and the exercise of warrants by former BlueWater Systems, Inc.
shareholders.

     We have a working capital revolving line of credit with Imperial Bank that
is secured by our accounts receivable. This facility allows us to borrow up to
the lesser of 80% of our eligible accounts receivable or $3.0 million and bears
interest at the bank's prime rate, which was 9.5% at July 12, 2000. The facility
expires in July 2001. The agreement under which the line of credit was
established contains certain covenants, including a provision requiring us to
maintain specified financial ratios. We were in compliance with these covenants
at June 30, 2000, and at that time there were no borrowings outstanding under
this credit facility.

     As of June 30, 2000, our principal commitments consisted of obligations
outstanding under operating leases. In October 1999, we began leasing
approximately 126,000 square feet in a single facility located in Bellevue,
Washington pursuant to a lease which expires in 2009. The annual cost of this
lease is approximately $3.0 million, subject to annual adjustments. Although we
have no other material commitments, we anticipate an increase in our capital
expenditures and lease commitments consistent with our anticipated growth in our
operations, infrastructure and personnel.

                                       26
<PAGE>   30

     We currently anticipate that we will continue to experience significant
increases in our operating expenses for the foreseeable future as we enter new
markets for our products and services, increase research and development
activities and sales and marketing activities, develop new distribution channels
and broaden our professional service capabilities. We believe that our existing
cash and cash equivalents and available bank borrowings will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures for
at least the next 12 months. We believe that we will be able to meet our
anticipated cash needs after that time from cash generated from operations and
do not currently anticipate the need to raise additional capital. If we do seek
to raise additional capital, there can be no assurance that additional financing
will be available on acceptable terms, if at all. We may use a portion of our
available cash to acquire additional businesses, products and technologies or to
establish joint ventures that we believe will complement our current or future
business. Pending such uses, we will invest our surplus cash in government
securities and other short-term, investment grade, interest-bearing instruments.

IMPACT OF THE YEAR 2000

     Even though we have not experienced any immediate adverse impact from the
transition to the year 2000, it is possible that other dates in the year 2000
may affect computer software and systems. While we believe that all of our
systems are year 2000 compliant, we may discover problems during 2000 that may
require expenditures in order for our computer and software systems to be
upgraded, modified or replaced. In addition, we do not currently have any
information concerning the year 2000 compliance status of our customers or other
parties with whom we do business. It is possible that some of the internal
systems of our customers or other parties with whom we do business have already
been or will be negatively affected by the year 2000 date change. We currently
have no contingency plan to manage any year 2000 issues that may arise.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as a part
of a hedge transaction and, if it is the type of hedge transaction. This
statement is effective for all fiscal quarters of all fiscal years beginning
after June 15, 2000. We do not use derivative instruments, therefore the
adoption of this statement will not have any effect on our results of operations
or financial position.

     In December 1999, SEC Staff Accounting Bulletin No. 101 (SAB 101), "Revenue
Recognition in Financial Statements," was issued. This pronouncement summarizes
certain of the Securities and Exchange Commission staff's views in applying
generally accepted accounting principles to revenue recognition. We are required
to adopt SAB 101 in the fourth quarter of 2000 with retroactive application to
January 1, 2000. We believe we are in compliance with the requirements of SAB
101.

     In March 2000, the Emerging Issues Task Force (EITF) of the FASB reached a
consensus on Issue No. 00-2, "Accounting for Web Site Development Costs," which
provides guidance on when to capitalize versus expense costs incurred to develop
a web site. We believe we are in compliance with the requirements of Issue No.
00-2.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     Interest Rate Risk. We do not hold derivative financial instruments or
equity securities in our investment portfolio. Our cash equivalents consist of
high-quality securities, as specified in our investment policy guidelines. The
policy limits the amount of credit exposure to any one issue or

                                       27
<PAGE>   31

issuer to a maximum of 20% of the total portfolio with the exception of treasury
securities, commercial paper and money market funds, which are exempt from size
limitation. The policy limits all short-term investments to mature in two years
or less, with the average maturity being one year or less. These securities are
subject to interest rate risk and will decrease in value if interest rates
increase.

     Foreign Currency Risk. Currently, the majority of our sales and expenses
are denominated in U.S. dollars, and, as a result, we have not experienced
significant foreign exchange gains and losses to date. While we have conducted
some transactions in foreign currencies and expect to continue to do so, we do
not anticipate that foreign exchange gains or losses will be significant. We
have not engaged in foreign currency hedging to date, although we may do so in
the future.

     Investment Risk. We have an investment in voting capital stock of a
privately-held technology company for business and strategic purposes. This
investment is included in other assets and is accounted for under the cost
method since our ownership is less than 20% and we do not have significant
influence. The securities do not have a quoted market price. Our policy is to
regularly review the operating performance in assessing the carrying value of
the investment.

     We review our long-lived assets, including goodwill, for impairment
whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable.

                                    BUSINESS

OVERVIEW

     We provide a broad range of products and services that facilitate the
integration of Microsoft Windows operating systems into a variety of devices we
call intelligent computing devices (ICDs), enhance the functionality of those
devices, and accelerate their deployment into the marketplace. Original
equipment manufacturers, semiconductor vendors, software developers, value added
resellers, internet service providers and network service providers rely on our
products and services to help bring customized intelligent computing devices and
intelligent computing device applications to market in a timely fashion. We have
been providing Windows CE-based software services since before the commercial
release of Windows CE in September 1996, and therefore we believe that we offer
a greater breadth and depth of Windows CE expertise than any of our current
competitors. In addition, in late 1999, we began offering Windows NT Embedded
integration services, thus expanding the breadth of our service offerings, and
in January 2000, our acquisition of BlueWater Systems broadened our product line
for developers of ICDs based on additional Windows operating systems including
Windows 98, Windows 2000, Windows NT and Windows NT Embedded. Our acquisition of
Mainbrace Corporation in May 2000 enables us to provide standard manufacturable
designs of popular ICDs such as Webpads, Web-phones, Pocket PCs, E-books and
portable data tablets, which together with our other products and services offer
customers a broad range of solutions to rapidly bring products to market.

     Intelligent computing devices are an emerging class of products with
sophisticated processing power that are designed for specific computing and
communications applications. Examples of intelligent computing devices include
television "set-top boxes," which sit on top of television sets and provide
users with interactive cable TV services, sophisticated video gaming features
and Internet access; handheld and palm-size PCs; gaming systems; handheld
industrial data collectors; consumer "Internet appliances" such as kiosk
terminals and navigational devices used in cars and trucks; and Windows-based
terminals, Webpads, E-books and Pocket PCs used both in the workplace and at
home. Compared to traditional computers, intelligent computing devices are often
less expensive and more adaptable in terms of their size, weight and shape,
while still providing sophisticated computing and communications capabilities,
including Internet connectivity.

     Increasingly, intelligent computing devices are able to connect directly to
the Internet, either through wired or wireless telecommunications systems. As
businesses and consumers increasingly use the Internet to transact business and
access information and as demand for smaller and more mobile devices grows,
original equipment manufacturers are developing new intelligent computing
devices to better meet the needs of end users. Because of space constraints and
other design and resource limitations inherent in the intelligent computing
device environment, original equipment manufacturers require a computer
operating system that is both scaleable and highly customizable, with lower
system requirements than traditional PC operating systems. There are several
different operating systems that can be used in intelligent computing devices.
Windows CE, a versatile and highly adaptable operating system modeled after
Microsoft Windows, is gaining market acceptance among original equipment
manufacturers as an operating system that meets these requirements. As increased
use of the Internet by consumers and businesses helps fuel the growth of the
intelligent computing device market, we believe that the market for Windows CE
will in turn benefit. In addition, the Windows NT Embedded operating system is
used for "computerizing" larger, more complex devices with a need for real time
functionality. Examples of devices for which Windows NT Embedded is designed
include Windows-based terminals, office machine equipment such as printers, and
telecommunications equipment such as routers and switching equipment.

                                       29
<PAGE>   33

     We develop products and provide services that facilitate the development of
Windows-based intelligent computing devices. We generate revenue in four
distinct ways. First, we provide software code-writing and related engineering
services to Microsoft and semiconductor vendors to adapt Windows CE software to
different microprocessors and to enhance Windows CE's user-specific features and
functions. Second, we offer a comprehensive set of software products and
services that help enable original equipment manufacturers to cost-effectively
integrate Windows CE, NTE and other Windows operating systems into their
intelligent computing devices. These offerings include original equipment
manufacturer adaptation kits, software development products, test programs and
Microsoft Windows CE licensing, along with engineering and quality assurance
services and training. Our service and product offerings are designed to ensure
that Windows works properly with the original equipment manufacturer's computer
boards, which are the internal hardware constituting the core of their
intelligent computing devices. We also offer software engineering services for
the integration of Window NT Embedded into ICDs, and for other Windows-based
operating systems we offer the BlueWater Systems software development products.
Third, we license a wide range of Windows based software applications to
original equipment manufacturers, value added resellers, Internet service
providers, network service providers and intelligent computing device consumers
to provide additional functions to Windows based intelligent computing devices,
such as printing and faxing capabilities, voice-over IP, remote device
management and wireless wide area least cost routing. Fourth, we license
standard manufacturing design of intelligent computing devices such as Webpads,
Web-phones, Pocket PCs, E-books and portable data tablets and bundle our
products and integration services for our customers.

INDUSTRY BACKGROUND

     The increasingly widespread use of electronic communications, including the
Internet, is enabling networks of businesses and consumers to collaborate,
access information and conduct business and personal interactions more
effectively. As the number of Internet users grows, so does the diversity of
content, services and applications available via the Internet. While the
Internet is already having a significant and highly visible impact on
business-to-consumer and consumer-to-consumer relationships, the market for
business-to-business Internet transactions is expected to expand at a greater
rate. According to a November 1998 report by Forrester Research entitled
"Re-sizing On-line Business Trade," U.S.-based Internet commerce between
businesses is expected to grow from $43 billion in 1998 to $1.3 trillion in
2003.

     As more businesses and consumers access the Internet, new ways of
conducting business electronically are emerging. Examples of users who are
leveraging this ability to communicate electronically include:

     - businesses that use mobile computing devices to permit their employees to
       access server-based network applications and the Internet from remote
       sites;

     - retail businesses that use handheld point-of-sale terminals to provide
       real-time inventory tracking, automate their procurement processes and
       publish information instantly to both internal and external users via the
       Internet;

     - healthcare professionals who use mobile computing devices to record and
       access patient information that can then be shared via the Internet among
       a broader group of professionals responsible for providing medical care;
       and

     - consumers who use Internet-enabled television set-top boxes, smart
       cellular phones, gaming systems and other devices to access Internet
       content, communicate and conduct transactions online.

     The increasing need for connectivity among both business and consumer users
is driving demand for easy-to-use, cost-effective and customizable methods of
electronic communication. Although the PC has been the traditional means of
electronically connecting suppliers, partners and customers, a new class is
emerging. This includes Internet-enabled television "set-top boxes," handheld
and palm-size PCs, gaming systems, handheld industrial data collectors, and
consumer "Internet appliances" such as kiosk terminals, vehicle navigational
devices, Webpads, E-books and Pocket PCs. These intelligent computing devices
are particularly attractive to business and consumer users because they are
often less expensive than traditional computers; have adaptable configurations,
including size, weight and shape; and are able to support a variety of
customized applications and user interfaces that can be designed for particular
tasks. In addition, these devices are typically compatible with existing
business information systems. According to information we received in August
1999 from International Data Corporation, a provider of information technology
data and industry analysis, the market for consumer information appliances, a
subset of the overall intelligent computing device market, is expected to grow
from $2.2 billion in 1998 to $18.7 billion in 2003.

     Because intelligent computing devices can be used for a number of purposes,
from consumer information to industrial automation, and can be designed for a
range of unique applications, the intelligent computing device industry is
characterized by a wide variety of hardware configurations and end-user
applications, each often designed for a specific market. To accommodate these
diverse characteristics in a cost-effective manner, semiconductor vendors and
original equipment manufacturers require operating systems that can be
integrated with a number of different intelligent computing devices and can
support an expanding range of industry-specific content and applications. The
Microsoft Windows family of operating systems, specifically Windows CE and
Windows NT Embedded, helps satisfy these requirements because it leverages the
existing industry-wide base of Microsoft Windows developers and technology
standards; can be customized to operate across a variety of intelligent
computing devices and integrate with existing information systems; offers
Internet connectivity; and reduces systems requirements compared to traditional
PC operating systems. Because of these characteristics, we believe Windows CE
and Windows NT Embedded are emerging as operating systems of choice for many
hardware and software applications vendors. Venture Development Corporation
estimates in a December 1998 report entitled "Windows CE and the Future of
Embedded Systems Development" that the number of intelligent computing devices
utilizing Windows CE will increase from just under one million units in 1999 to
more than 14 million units by 2003.

     To take advantage of the multiple benefits of these Windows operating
systems, many original equipment manufacturers and semiconductor vendors require
the services of a software product and service provider with the breadth of
experience and depth of capabilities to fully support the Windows CE and Windows
NT Embedded operating systems and related applications across different
semiconductors and intelligent computing devices. These products and services
should encompass the full cycle of the intelligent computing device development
process, including hardware support, software development products and services,
system validation and end-user software applications. In addition, these
products and services should use existing Microsoft and other industry
technologies and standards to promote rapid low-cost development, reduced
time-to-market and integration with existing enterprise software applications.
These products and services should also be designed to accommodate the varying
industry-specific needs of semiconductor, equipment and software developers
without compromising functionality and performance.

TECHNOLOGY

     We have developed a set of technologies incorporated in the software
products described under "-- Integration of Windows CE and Windows NT Embedded
with intelligent computing devices -- Products" that are used by original
equipment manufacturers to integrate Windows CE with their computer boards, the
internal hardware constituting the core of their intelligent computing devices.
The technology contained in our CE Xpress Suite, including the Original
Equipment Manufacturer Adaptation Layer, the CE Platform Layer and the Device
Driver Library, provides the interface between Windows CE and the computer board
contained within the intelligent computing device. The basic features and
functions of these technologies are described below.

Original Equipment Manufacturer Adaptation Layer Library

     The Original Equipment Manufacturer Adaptation Layer provides a standard
interface between the Windows CE operating system and the core components of an
intelligent computing device's computer board. A new board-specific Original
Equipment Manufacturer Adaptation Layer must be implemented for each computer
board that will be using Windows CE.

     We maintain a library of Original Equipment Manufacturer Adaptation Layers
for several of the computer boards used in Windows CE-based intelligent
computing device products. These Original Equipment Manufacturer Adaptation
Layers are distributed to our customers in our CE Xpress Suite and are also used
by our engineers when we are contracted to create custom solutions. In addition,
our Original Equipment Manufacturer Adaptation Layer library serves as a
starting point for the creation of new Original Equipment Manufacturer
Adaptation Layer implementations.

                                       40
<PAGE>   44

Device Driver Library

     Device drivers provide the interface by which the Windows CE operating
system controls any peripheral devices, including keyboards, display screens and
computer network interface cards, that may be connected to an intelligent
computing device's computer board. A separate device driver must be implemented
for each peripheral device connected to a Windows CE-enabled computer board.

     We have created a library of device drivers for inclusion in our CE Xpress
Suite and for use in the custom software products and services we provide to our
customers. The existing set of drivers also provides starting points for the
creation of new device drivers.

CE Platform Layer

     A peripheral device normally requires a different device driver for each
model of computer board to which it is to be connected. A device driver for one
model of computer board will not generally work with a different model of
computer board.

     Our CE Platform Layer technology allows our engineers and third-party
hardware manufacturers to develop a single driver for a peripheral device that
may then be used on many different models of computer boards. This increases the
value and flexibility of each computer board by increasing the number of readily
available peripheral devices that can be used.

     Our CE Platform Layer technology is included in our CE Xpress Suite and is
used for the implementation of the majority of our device drivers.

CEValidator

     Our CEValidator product is a quality assurance and testing tool which we
originally developed for in-house use. We believe that it is important to test
devices early in the design process and to continue testing at a high frequency
throughout the development cycle. We have designed our CEValidator to support
such a testing pattern. CEValidator is based on two primary components:

     - a broad suite of over 1,000 tests which evaluate the various subsystems
       of Windows CE. These tests have been developed by our engineers in the
       course of our own software development efforts. In addition, CEValidator
       allows original equipment manufacturers to add their own test suites to
       evaluate specific features of their intelligent computing devices.

     - a test control system. This system manages the execution of the tests
       suite and the recording of test results. CEValidator provides
       communication features which control testing over network connections, a
       graphical user interface for displaying user controls and test results,
       and simultaneous testing capabilities for multiple systems.

CUSTOMERS

     Microsoft is our largest customer, representing approximately 35%, 75%, 85%
and 68% of our total revenue in 1997, 1998, 1999 and the first six months of
2000, respectively. Our other target customers include semiconductor vendors and
original equipment manufacturers seeking to leverage the numerous benefits of
Windows-based operation systems in order to develop high quality, full-feature
products that meet the complex and evolving requirements of numerous
end-markets.

     We maintain strategic relationships with Microsoft to promote its
Windows-based operating systems across a broad range of industries and
applications. Our relationship with Microsoft extends to the following:

     Development partner. Under the terms of our master agreement, we are a
"preferred Microsoft vendor" for Windows CE. Approximately 160 of our software
engineers work on a number of

                                       41
<PAGE>   45

different Windows CE-based projects for Microsoft and on the development of
Windows CE-related software tools under various work plans. These software tools
are then provided by Microsoft under the Microsoft name to semiconductor vendors
and various original equipment manufacturers utilizing Windows CE. We bill
Microsoft on a time-and-materials basis, although each project has a maximum
dollar cap. A separate work plan is generated for each project, which can then
be modified or terminated by Microsoft at any time.

     Porting Partner. We are the exclusive partner of Microsoft for providing
software engineering services to semiconductor manufacturers seeking Windows CE
software support for the year 2000. Microsoft may expand this program to other
companies in the future.

     Systems integrator. We are a Microsoft-sanctioned systems integrator for
Windows CE, as indicated on the "embedded Windows CE" portion of Microsoft's
website. In this capacity, we provide training, consulting and software
engineering services and products to original equipment manufacturers that are
building Windows CE-based intelligent computing devices. We actively participate
in the Microsoft systems integrator program, including participating with
Microsoft in "partner pavilions" at trade shows and listing our services and
posting our product announcements on the "embedded Windows CE" portion of
Microsoft's website. In addition, Microsoft has periodically utilized our
services when an original equipment manufacturer has required additional
software engineering services.

     Windows CE distributor. We are a licensed distributor of the Windows CE
operating system. We sub-license Windows CE by reselling the right to bundle
this operating system in intelligent computing devices. Microsoft actively
assists and manages its distributors to secure additional licensing
opportunities for Windows CE. We are promoted on the "embedded Windows CE"
portion of Microsoft's website as a distributor, and Microsoft shares with us
leads generated from Web inquiries and tradeshows.

     Windows CE independent software vendor. Microsoft actively encourages
third-party application development through its Developer Relations Group and
Windows CE logo program, which allows third-party applications to receive
Windows CE compatibility logos. We develop several software applications for a
wide variety of Windows CE-based intelligent computing devices, which we market
under our brand names, including bFAX and bPRINT. We also participate in
marketing opportunities offered by Microsoft for third-party developers to
promote our software applications. In addition, Microsoft has from time to time
demonstrated our applications in connection with demonstrations to third parties
of its Windows CE operating system.

SALES AND MARKETING

     We market our services to different semiconductor vendors through our
direct sales force. We market our software tools products and related services
that help original equipment manufacturers integrate Windows CE into their
intelligent computing devices through our direct sales force, as well as through
third-party representatives and distributors. We market our Windows CE-based
software applications either bundled by original equipment manufacturers onto
particular intelligent computing devices or purchased directly by consumers for
their intelligent computing devices through our direct sales force, third-party
representatives, distributors, or other consumer retail channels. We have direct
sales offices in the United States, Germany and Japan. As of June 30, 2000, we
had 42 employees in our sales and marketing department. Key elements of our
sales and marketing strategy include direct advertising, event marketing, an
active public relations program, channel marketing programs, customer and
strategic alliance partner co-marketing programs and a comprehensive website.

     We are currently developing new sales channels, including value-added
resellers and systems integrators. We believe that these additional channels
will further increase the brand awareness of our

                                       42
<PAGE>   46

software products and services and will further promote the development of
software infrastructures for Windows CE-based intelligent computing devices.

RESEARCH AND DEVELOPMENT

     As of June 30, 2000, we had 370 engineers engaged in software engineering
services and research and development. Our research and development teams are
responsible for the design, development and release of our products. Members of
our research and development staff work closely with our sales and marketing
department, as well as with our customers and potential customers, to better
understand market needs and requirements.

     A substantial majority of our research and development engineers are
involved in the development of the Windows CE operating system and accompanying
tools for Microsoft. These responsibilities require significant expertise due to
the radically different nature of the microprocessors and other hardware
components used in Windows CE-based intelligent computing devices. This team has
accumulated detailed knowledge of the Windows CE environment over the past six
years, allowing us to continue to develop software products and services that
enable the expanding capability and compatibility of Windows CE-based
intelligent computing devices. To ensure that compatibility goals are met and
that a high level of product quality is achieved, quality assurance groups
within this team subject our products to tens of thousands of individual tests
in multiple test configurations before the products are released to our
customers. Due to the broad variety of hardware that hosts Windows CE, the
quality assurance groups have had to develop a special expertise in managing and
extending the test tools used to validate the tool kits for these diverse
operating environments.

     The remainder of our research and development engineers provide services
and develop Windows CE software for both end-user markets and
product/application developers. The software engineers in this team are
responsible for the development of commercial applications that provide added
breadth and functionality for Windows CE-based intelligent computing devices as
well as standard products used in the development and testing of new products
utilizing the Windows CE operating system. Our engineers have significant
experience in creating products for Windows CE, which enables us to bring
products to market in a timely manner.

COMPETITION

     We face competition from:

     - our current and potential customers' internal research and development
       departments that may seek to develop their own proprietary products and
       solutions;

     - large professional engineering services firms;

     - established intelligent computing device software and tools
       manufacturers;

     - small- and medium-size engineering services; and

     - software and component distributors.

     As we develop new products, particularly products focused on specific
industries, we may begin competing with companies with whom we have not
previously competed.

     We compete principally on the basis of the breadth of software products and
services offered, the experience of the providers, the quality of the software
products and services, the time-to-market and price. We believe we compete
favorably in each of these areas.

INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS

     Intellectual property is critical to our success. In general, we attempt to
protect our intellectual property rights through patent, copyright, trademark
and trade secret laws and contractual arrangements. There can, however, be no
assurance that our efforts will be effective to prevent misappropriation of our
technology, or to prevent the development and design by others of products or
technologies similar to or competitive with those developed by us.

     We currently have four pending U.S. patent applications. We do not have any
issued patents. BSQUARE, bFAX and BSQUARE View are our registered trademarks.
Additionally, bTRACK, bREADY, bFIND, bPRINT, bMOBILE, bUSEFUL, bTASK,
bPRODUCTIVE, bSTART and CEValidator are our trademarks. We will continue to
pursue registration of these and other marks. This prospectus also contains
trademarks and tradenames of other companies.

EMPLOYEES

     As of June 30, 2000, we had 459 employees, excluding independent
contractors and other temporary employees, including 370 employees in software
engineering services and product development, 42 employees in sales and
marketing and 47 employees in general and administrative services (including
executive officers). Of these employees, 445 are located in the United States,
five are located in Germany and nine are located in Japan. In addition, from
time to time, we employ temporary employees and consultants. None of our
employees is represented by a labor union, and we consider our relations with
our employees to be good.

FACILITIES

     We lease approximately 126,000 square feet of space in a single location in
Bellevue, Washington, pursuant to a lease that expires in 2009, with the option
to renew for up to an additional 20 years. We also lease office space in
Sunnyvale, California, Munich, Germany and Tokyo, Japan. We believe that our
facilities will be adequate to meet our needs for at least the next 12 months.

LEGAL PROCEEDINGS

     We are not currently involved in any material legal proceedings.

BOARD OF DIRECTORS

     We currently have authorized seven directors; however, one board seat is
vacant. Pursuant to our amended and restated articles of incorporation, our
board of directors is divided into three classes, each with staggered three-year
terms. To facilitate the transition to staggered terms, Scot E. Land and William
Larson were elected at the 2000 annual meeting of our shareholders as Class I
directors

                                       46
<PAGE>   50

for a one-year term ending in 2001, Albert T. Dosser and Jeffrey T. Chambers
were elected as Class II directors for a two-year term ending in 2002, and
William T. Baxter and David M. Moore were elected as Class III directors for a
three-year term ending in 2003. When the vacant Board seat is filled, such
director will be a Class I director. At each subsequent annual meetings of
shareholders, one class of directors will be elected with the other classes
continuing for the remainder of their respective three-year terms.

Committees

     Our board of directors currently has an audit committee and a compensation
committee. The audit committee consists of Mr. Chambers and Mr. Land. The audit
committee makes recommendations to our board of directors regarding the
selection of independent auditors, reviews the scope of audit and other services
by our independent auditors, reviews the accounting principles and auditing
practices and procedures to be used for our financial statements and reviews the
results of our audits. The compensation committee consists of Mr. Chambers and
Mr. Land. The compensation committee reviews and approves the compensation and
benefits for our executive officers, grants stock options under our stock option
plan and makes recommendations to our board of directors on compensation
matters.

Compensation Committee Interlocks and Insider Participation

     No interlocking relationship exists between any member of our board of
directors or compensation committee and any member of the board of directors or
compensation committee of any other company, nor has any such interlocking
relationship existed in the past.

     In January 1998, we sold 8,333,333 shares of Series A Preferred Stock at a
per share price of $1.80. Purchasers of Series A Preferred Stock, which was
converted to common stock upon consummation of our initial public offering in
October 1999, included:

     - TA Associates and its affiliates, who collectively purchased 6,666,667
       shares and are beneficial owners of 21% of our outstanding common stock
       on an as-converted basis as of June 30, 2000. One of our directors,
       Jeffrey T. Chambers, is a managing director of TA Associates; and

     - Encompass Ventures and its affiliates, who collectively purchased
       1,666,666 shares and are beneficial owners of 5% of our outstanding
       common stock on an as-converted basis as of June 30, 2000. One of our
       directors, Scot E. Land, is a managing director of Encompass Ventures.

     In September 1998, we granted an option to purchase 125,000 shares of
common stock at an exercise price of $1.00 per share to Encompass Europe, Inc.
(formerly NextGen), an affiliate of Encompass Ventures, in exchange for
consulting services. After the option vested with regard to 41,666 of such
shares, the consulting arrangement was terminated, precluding the vesting of the
remaining portion of the option.

     We have also granted options to purchase common stock to Messrs. Chambers
and Land. Because of contractual obligations involving Mr. Chambers and his
affiliated investment entities, the option grant to Mr. Chambers was issued in
the name of TA Associates, Inc.

Compensation

     Our directors are reimbursed for expenses incurred in connection with
attending board and committee meetings but are not otherwise compensated for
their services as board members. In August 1998, we granted to each of TA
Associates, with whom Jeffrey T. Chambers, one of our directors, is affiliated,
and Scot E. Land, one of our directors, an option to purchase 45,000 shares of
our common stock at an exercise price of $1.80 per share, vesting in three
annual installments of

                                       47
<PAGE>   51

15,000 shares each. Moreover, in October 1999, we granted to Mr. Land an option
to purchase 40,000 shares of our common stock at an exercise price of $12.00 per
share, vesting in four annual installments of 10,000 shares each. In July 1998,
we granted to William Larson, one of our directors, an option to purchase
120,000 shares of our common stock at an exercise price of $1.80 per share,
vesting in three annual installments of 40,000 shares each. In October 1999, we
granted to David Moore, one of our directors, an option to purchase 35,000
shares of our common stock at an exercise price of $39.56 per share, vesting in
three annual installments of approximately 11,667 shares each. We currently
intend to make comparable option grants to future non-employee directors.

     Our executive officers are elected by, and serve at the discretion of, our
board of directors. There are no family relationships among our directors and
officers.

Option Grants in Fiscal Year 1999

     The following table sets forth certain information with respect to stock
options granted to each of our named executive officers during the fiscal year
ended December 31, 1999. In accordance with the rules of the SEC, also shown
below is the potential realizable value over the term of the option, the

                                       48
<PAGE>   52

period from the grant date to the expiration date, based on assumed rates of
stock appreciation of 5% and 10%, compounded annually. These rates are mandated
by the SEC and do not represent our estimate of future stock price. Actual
gains, if any, on stock option exercises will depend on the future performance
of our common stock. In the fiscal year ended December 31, 1999, we granted
options to acquire up to an aggregate of 1,345,795 shares of common stock to
employees and directors, all under our stock option plan and all at an exercise
price equal to the fair market value of our common stock on the date of grant.

EMPLOYEE BENEFIT PLANS

Stock Option Plans

     We have an amended and restated stock option plan pursuant to which options
to purchase common stock are granted to our officers and employees. Our board of
directors adopted and our shareholders approved our amended and restated stock
option plan in May 1997. At our 2000 annual meeting of shareholders, this stock
option plan was further amended to annually increase the number of shares
reserved for issuance during each of our fiscal years beginning on January 1,
2000 by an amount equal to the lesser of (A) four percent (4%) of our
outstanding shares at the end of such fiscal year or (B) an amount determined by
our board of directors. As of June 30, 2000, we had reserved a total of
4,347,799 shares of common stock for issuance under the stock option plan. The
stock option plan provides for the granting to our employees, including officers
and directors, of

                                       49
<PAGE>   53

incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986 and for the granting to employees, consultants and
non-employee directors of nonstatutory stock options. If an optionee would have
the right in any calendar year to exercise for the first time incentive stock
options for shares having an aggregate fair market value (determined for each
share as of the date the option to purchase the shares was granted) in excess of
$100,000, any such excess options shall be treated as nonstatutory stock
options. Unless terminated earlier by our board of directors, the plan will
terminate in May 2007.

     The stock option plan may be administered by the our board of directors or
a committee of the board. Our board of directors determines the terms of each
option granted under the stock option plan, including the number of shares
subject to an option, exercise price, vesting schedule and duration. The
exercise price of all incentive stock options granted under the stock option
plan cannot be less than the fair market value of the common stock on the date
of grant and, in the case of incentive stock options granted to holders of more
than 10% of our voting power, not less than 110% of the fair market value.
Generally, options granted under the stock option plan have a term of ten years,
vest annually over a four-year period and are nontransferable. Payment of the
exercise price of options may be made in cash or other consideration as
determined by our board of directors.

     Our board of directors has the authority to amend or terminate the stock
option plan as long as such action does not adversely affect any outstanding
option and provided that shareholder approval for any amendments to the stock
option plan shall be obtained to the extent required by applicable law.

     We also have a stock option plan pursuant to which options to purchase
common stock have been granted to employees of one of our subsidiaries. As of
June 30, 2000, options to purchase an aggregate of 4,347,799 shares of common
stock were outstanding under our stock option plans at a weighted average
exercise price of $7.52 per share and 605,127 shares had been issued upon
exercise of options.

Employee Stock Purchase Plan

     Our board of directors and shareholders adopted an employee stock purchase
plan in August 1999, which was implemented as of October 19, 1999. The employee
stock purchase plan provides a convenient and practical means by which employees
may participate in stock ownership. Our board of directors believes that the
opportunity to acquire a proprietary interest in our success through the
acquisition of shares of common stock pursuant to the employee stock purchase
plan is an important aspect of our ability to attract and retain highly
qualified and motivated employees. The employee stock purchase plan is intended
to qualify as an "employee stock purchase plan" within the meaning of Section
423 of the Internal Revenue Code. The employee stock purchase plan may be
administered by our board of directors or by a committee appointed by the board.
The plan administrator has the power to make and interpret all rules and
regulations it deems necessary to administer the employee stock purchase plan.
Our board of directors has broad authority to amend the employee stock purchase
plan, subject in some instances to shareholder approval. All of our employees
who customarily work more than 20 hours per week, including officers, are
eligible to participate in the employee stock purchase plan. Eligible employees
may elect to contribute from 1% to 10% of the compensation paid to them during
each pay period towards stock purchases under the plan. Other than the first
offering, which will have a duration of approximately 19 months, each
participant may enroll in an 18-month offering in which shares of common stock
are purchased on the last day of each six-month period during the offering. The
first offering commenced on October 19, 1999 and will terminate on May 14, 2001.
Thereafter, a separate offering will commence

                                       50
<PAGE>   54

on November 15 and May 15 of each year. The purchase price for shares purchased
under the employee stock purchase plan will be equal to 85% of the lower of:

     - the fair market value of the common stock on the enrollment date of the
       offering; or

     - the fair market value on the date of purchase.

Neither payroll deductions credited to an employee's account nor any rights with
regard to the purchase of shares under the employee stock purchase plan may be
assigned, transferred, pledged or otherwise disposed of in any way by a
participant, except that a participant may designate a beneficiary in the event
of his or her death.

     Upon termination of employment due to death, retirement or disability, the
payroll deductions credited to an employee's account will be used to purchase
shares on the next purchase date. Any remaining balance will be returned to the
participant or his or her beneficiary. Upon termination of employment for any
other reason, any payroll deductions credited to an employee's account will be
returned to the participant. We have authorized the issuance of up to 1,500,000
shares of common stock under the employee stock purchase plan. In the event of a
merger, consolidation or acquisition by another corporation of all or
substantially all of our assets, each outstanding right to purchase shares under
the employee stock purchase plan shall be assumed or an equivalent stock
purchase right substituted by the successor corporation. If the successor
corporation refuses to assume or substitute for the stock purchase right, the
offering period during which a participant may purchase stock will be shortened
to a specified date before the proposed merger or sale. Similarly, in the event
of our liquidation or dissolution, the offering period during which a
participant may purchase stock will be shortened to a specified date before the
date of the liquidation or dissolution.

401(k) Plan

     In March 1997, our board of directors adopted a tax-qualified employee
savings and retirement plan for eligible U.S. employees. Eligible employees may
elect to defer a percentage of their eligible compensation in the 401(k) plan,
subject to the statutorily prescribed annual limit. We make matching
contributions on behalf of all participants in the 401(k) plan in the amount
equal to one-half of the first 6% of an employee's contributions. Matching
contributions are subject to a vesting schedule; all other contributions are at
all times fully vested. We intend the 401(k) plan to qualify under Sections
401(k) and 501 of the Internal Revenue Code so that contributions by employees
or us to the 401(k) plan, and income earned, if any, on plan contributions, are
not taxable to employees until withdrawn from the 401(k) plan, and so that we
will be able to deduct our contributions when made. The trustee of the 401(k)
plan, at the direction of each participant, invests the assets of the 401(k)
plan in any of a number of investment options.

EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL ARRANGEMENTS

     We currently do not have any employment agreements with any of its named
executive officers. Our stock option plan provides that in the event a third
party acquires us through the purchase of all or substantially all of our
assets, a merger or other business combination, if so provided in applicable
stock option agreements, the unexercised portion of outstanding options will
vest and become immediately exercisable. Only two of our officers have stock
option agreements that contain change of control provisions. David Bialer has a
stock option agreement which provides for the acceleration of vesting of 50% of
any unvested portion of his options in the event a third party acquires us. In
addition, Brian V. Turner has a stock option agreement pursuant to which his
options are all immediately vested but subject to repurchase by us over a period
of four years from the date of grant. Mr. Turner's option agreement also
provides for the release of 50% of any unreleased portion of his options in the
event a third party acquires us. We do not have change of control arrangements
with any of the other named executive officers.

DIRECTOR AND OFFICER INDEMNIFICATION AND LIABILITY

     Our amended and restated articles of incorporation limit the liability of
directors and officers to the fullest extent currently permitted by the
Washington Business Corporation Act or as it may be amended in the future.
Consequently, subject to the WBCA, no director will be personally liable to us
or our shareholders for monetary damages resulting from his conduct as our
director, except liability for:

     - acts or omissions involving intentional misconduct or knowing violations
       of law;

     - unlawful distributions; or

     - transactions from which the director personally receives a benefit in
       money, property or services to which the director is not legally
       entitled.

     Our amended and restated articles of incorporation also provide that we
shall indemnify any individual made a party to a proceeding because that
individual is or was one of our directors or officers and shall advance or
reimburse reasonable expenses incurred by such individual in advance of the
final disposition of the proceeding to the fullest extent permitted by
applicable law. Any repeal of or modification to our amended and restated
articles of incorporation may not adversely affect any right of any of our
directors who is or was a director at the time of such repeal or modification.
To the extent the provisions of our amended and restated articles of
incorporation provide for indemnification of directors for liabilities arising
under the Securities Act, those provisions are, in the opinion of the SEC,
against public policy as expressed in the Securities Act and are therefore
unenforceable.

     Our bylaws provide that we shall indemnify our directors and officers and
may indemnify our employees and agents to the fullest extent permitted by law.
In addition, we have entered into separate indemnification agreements with our
directors and certain executive officers that could require us, among other
things, to indemnify them against liabilities that arise because of their status
or service as directors or executive officers and to advance their expenses
incurred as a result of any proceeding against them as to which they could be
indemnified. Finally, we have purchased and intend to maintain a liability
insurance policy, pursuant to which our directors and officers may be
indemnified against liability they may incur for serving in their capacities as
our directors and officers. We believe that the limitation of liability
provisions in our amended and restated articles of incorporation, the
indemnification provisions in our bylaws, the indemnification agreements and the
liability insurance policy will facilitate our ability to continue to attract
and retain qualified individuals to serve as our directors and officers.

                             PRINCIPAL SHAREHOLDERS

     The following table sets forth certain information regarding the beneficial
ownership of our common stock as of June 30, 2000 by:

     - each person we know to own beneficially more than five percent of the
       outstanding shares of common stock;

     - each of our directors;

     - each of our executive officers named in the Summary Compensation Table in
       "Executive Compensation" in this prospectus; and

     - all of our directors and executive officers as a group.

     Beneficial ownership is determined in accordance with the rules of the SEC.
For purposes of calculating the number of shares beneficially owned by a
shareholder and the percentage ownership of that shareholder, shares of common
stock subject to options that are currently exercisable or exercisable within 60
days of June 30, 2000 by that shareholder are deemed outstanding. These options
are listed below under the heading "Number of Shares Underlying Options" and are
not treated as outstanding for the purpose of computing the percentage ownership
of any other shareholder. Percentage ownership is based on 33,481,045 shares of
common stock outstanding as of June 30, 2000.

     Unless otherwise noted below, the address for each shareholder listed below
is: c/o BSQUARE Corporation, 3150 139th Avenue S.E., Bellevue, Washington 98005.
Unless otherwise noted, each of the shareholders listed below has sole
investment and voting power with respect to the common stock indicated, except
to the extent shared by spouses under applicable law.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     As of the date of this prospectus, we are authorized to issue up to
150,000,000 shares of common stock, no par value, and 10,000,000 shares of
preferred stock, no par value. The following summary of certain provisions of
our common stock and preferred stock is not complete and may not contain all the
information you should consider before investing in the common stock. This
description is subject to and qualified in its entirety by provisions of our
amended and restated articles of incorporation and bylaws, which are included as
exhibits to the registration statement of which this prospectus is a part, and
by provisions of applicable Washington law.

COMMON STOCK

     As of June 30, 2000, there were 33,481,045 shares of common stock
outstanding that were held of record by 209 shareholders. As of June 30, 2000,
there were outstanding options to purchase a total of 4,347,799 shares of common
stock.

     The holders of common stock are entitled to one vote per share on all
matters to be voted on by the shareholders. Subject to preferences that may be
granted to any outstanding shares of preferred stock, the holders of common
stock are entitled to receive ratably only those dividends our board of
directors declares out of funds legally available for the payment of dividends
as well as any other distributions to the shareholders.

     If we are liquidated, dissolved or wound-up, the holders of common stock
are entitled to share pro rata all of our assets remaining after payment of our
liabilities and liquidation preferences of any then-outstanding shares of
preferred stock. Holders of common stock have no preemptive rights or rights to
convert their common stock into any other securities. There are no redemption or
sinking fund provisions applicable to the common stock. All outstanding shares
of common stock are fully paid and non-assessable, and the shares of common
stock to be issued in this offering will be fully paid and non-assessable.

ANTITAKEOVER EFFECTS OF CERTAIN PROVISIONS OF OUR AMENDED AND RESTATED ARTICLES
OF INCORPORATION, BYLAWS AND WASHINGTON LAW

     Our board of directors, without shareholder approval, has the authority
under our amended and restated articles of incorporation to issue preferred
stock with rights superior to the rights of the holders of common stock. As a
result, preferred stock could be issued quickly and easily, could adversely
affect the rights of holders of common stock and could be issued with terms
calculated to delay or prevent a change in control of us or make removal of our
management more difficult. In addition, our board of directors is divided into
three classes. The directors in each class serve for three-year terms, one class
being elected each year by our shareholders, and directors can only be removed
for cause. This system of electing and removing directors may tend to discourage
a third party from making a tender offer or otherwise attempting to obtain
control of our company because it generally makes it more difficult for
shareholders to replace a majority of the directors.

     Chapter 19 of the Washington Business Corporation Act generally prohibits a
"target corporation" from engaging in certain significant business transactions
with an "acquiring person," which is defined as a person or group of persons
that beneficially owns 10% or more of the voting securities of the target
corporation, for a period of five years after the acquisition, unless the
transaction or acquisition of shares is approved by a majority of the members of
the target

                                       56
<PAGE>   60

corporation's board of directors prior to the time of acquisition. Prohibited
significant business transactions include, among other things:

     - a merger or consolidation with, disposition of assets to, or issuance or
       redemption of stock to or from, the acquiring person;

     - termination of 5% or more of the employees of the target corporation as a
       result of the acquiring person's acquisition of 10% or more of the
       shares; or

     - allowing the acquiring person to receive any disproportionate benefits as
       a shareholder.

     After the five-year period, a "significant business transaction" may occur
as long as it complies with certain "fair price" provisions of the statute. A
corporation may not "opt out" of this statute. This provision may have the
effect of delaying, deterring or preventing a change in control of our company.

     In addition, our bylaws provide that shareholders may not raise new matters
or nominate directors at a meeting of shareholders unless advance notice
requirements are satisfied, which could have the effect of delaying or deterring
a change in control of us.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     Any distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common stock
in Canada must be made in accordance with applicable securities laws which will
vary depending on the relevant jurisdiction, and which may require resales to be
made in accordance with available statutory exemptions or under a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice prior to any resale of the common
stock.

REPRESENTATIONS OF PURCHASERS

     Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom the
purchase confirmation is received that (1) the purchaser is entitled under
applicable provincial securities laws to purchase common stock without the
benefit of a prospectus qualified under the securities laws, (2) where required
by law, that the purchaser is purchasing as principal and not as agent, and (3)
the purchaser has reviewed the text under "Resale Restrictions."

RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

ENFORCEMENT OF LEGAL RIGHTS

     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer and these persons. All or a substantial portion of the assets of the
issuer and these persons may be located outside of Canada and, as a result, it
may not be possible to satisfy a judgment against the issuer or these persons in
Canada or to enforce a judgment obtained in Canadian courts against the issuer
or these persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that the purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser in this offering. This report must be in
the form attached to British Columbia Securities Commission Blanket Order BOR
#95/ 17, a copy of which may be obtained from us. Only one report must be filed
in respect of common stock acquired on the same date and under the same
prospectus exemption.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To BSQUARE Corporation:

     We have audited the accompanying consolidated balance sheets of BSQUARE
Corporation and subsidiaries as of December 31, 1999 and 1998, and the related
consolidated statements of income and comprehensive income, shareholders' equity
(deficit) and cash flows for each of the three years in the period ended
December 31, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of BSQUARE
Corporation and subsidiaries as of December 31, 1999 and 1998, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

     BSQUARE Corporation, a Washington corporation, and its subsidiaries
(collectively the Company) provides a variety of software products and services
that facilitate the integration of the Microsoft Windows-based operating systems
into a wide variety of intelligent computing devices. The Company works with
semiconductor vendors and original equipment manufacturers to provide software
products and engineering services for the development of intelligent computing
devices.

     The Company helps enable the rapid and low-cost deployment of intelligent
computing devices by providing a variety of software products and services for
the development, integration and deployment of Windows-based operating systems
with industry-specific applications. The Company also develops software
applications that are licensed to end users to provide intelligent computing
devices with additional functionality. The Company markets and supports its
products and provides services on a worldwide basis through a direct sales force
augmented by distributors.

CERTAIN SIGNIFICANT RISKS AND UNCERTAINTIES

     The Company operates in the software industry, and accordingly, can be
affected by a variety of factors. For example, management of the Company
believes that any of the following factors could have a significant negative
effect on the Company's future financial position, results of operations and
cash flows: unanticipated fluctuations in quarterly operating results; failure
of the market for Windows CE operating system to develop fully; failure of the
market for intelligent computing devices to develop fully; adverse changes in
the Company's relationship with Microsoft; failure to secure contracts with
market-leading original equipment manufacturers; intense competition; failure to
attract and retain key personnel; failure to protect intellectual property;
risks associated with international operations; inability to manage growth; and
litigation or other claims against the Company.

BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. Significant intercompany accounts and
transactions have been eliminated. Accounts denominated in foreign currencies
have been re-measured into the functional currency, using the U.S. dollar as the
functional currency.

     The consolidated financial statements as of June 30, 2000 have been
prepared by the Company pursuant to the rules and regulations of the Securities
and Exchange Commission and include the accounts of the Company. Certain
information and footnote disclosures, normally included in financial statements
prepared in accordance with generally accepted accounting principles, have been
condensed or omitted pursuant to such rules and regulations. In the opinion of
the Company, the unaudited financial statements reflect all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the Company's financial position at June 30, 2000, its operating
results and cash flows for the six-months ended June 30, 2000 and 1999.

     On January 5, 2000, the Company acquired BlueWater Systems, Inc. in a
transaction accounted for as a pooling of interests. The consolidated financial
statements and notes thereto have been restated for all periods presented to
include the accounts and operations of BlueWater Systems, Inc. as if it had
always been a part of BSQUARE.

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, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

EARNINGS PER SHARE

     In accordance with Statement of Financial Accounting Standards (SFAS) No.
128, "Computation of Earnings Per Share," basic earnings per share is computed
by dividing net income available to common shareholders (net income less
accretion of mandatorily redeemable convertible preferred stock) by the weighted
average number of shares of common stock outstanding during the period. Dilutive
earnings per share is computed by dividing net income by the weighted average
number of common and dilutive common equivalent shares outstanding during the
period. Common equivalent shares consist of the shares of common stock issuable
upon the conversion of the mandatorily redeemable convertible preferred stock
(using the if-converted method) and shares issuable upon the exercise of stock
options and warrants (using the treasury stock method); common equivalent shares
are excluded from the calculation if their effect is antidilutive. The Company
has not had any issuances or grants for nominal consideration as defined under
Staff Accounting Bulletin 98.

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include demand deposits, money market accounts
and all highly liquid debt instruments with an original maturity date of three
months or less.

SHORT-TERM INVESTMENTS

     The Company's short-term investments consist primarily of investment-grade
marketable securities, which are classified as held to maturity and recorded at
amortized cost. Due to the short-term nature of these investments, changes in
market interest rates would not have a significant impact on the fair value of
these securities that are carried at amortized cost, which approximates fair
value.

     At December 31, 1998 and 1999, and as of June 30, 2000, all short-term
investments had a contractual maturity of two years or less.

FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK

     The Company has the following financial instruments: cash and cash
equivalents, short-term investments, accounts receivable, accounts payable,
accrued liabilities, bank lines of credit and standby letters of credit. The
carrying value of cash and cash equivalents, short-term investments, accounts
receivable, accounts payable, and accrued liabilities approximate fair value
based on the liquidity of these financial instruments or based on their short
term nature. The carrying value of bank lines of credit, and standby letters of
credit approximates fair value based on the market interest rates available to
the Company for debt of similar risk and maturities.

     The Company performs initial and ongoing evaluations of its customers'
financial position, and generally extends credit on open account, requiring
collateral as deemed necessary. The Company maintains allowances for potential
credit losses.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

FURNITURE, EQUIPMENT AND LEASEHOLD IMPROVEMENTS

     Furniture, equipment and leasehold improvements are stated at cost less
accumulated depreciation. Depreciation is provided on the straight-line method
over the estimated useful lives, as follows: office furniture and equipment --
four years; computer equipment -- three years. Leasehold improvements are
amortized over the shorter of the lease term or the estimated useful life.
Maintenance and repairs are expensed as incurred. When properties are retired or
otherwise disposed, gains or losses are reflected in the income statement. When
facts and circumstances indicate that the cost of long-lived assets may be
impaired, an evaluation of recoverability is performed by comparing the carrying
value of the asset to projected future cash flows. Upon indication that the
carrying value of such assets may not be recoverable, the Company would
recognize an impairment loss by a charge against current operations.

SOFTWARE DEVELOPMENT COSTS

     Under the criteria set forth in Statement of Financial Accounting Standards
No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or
Otherwise Marketed," capitalization of software development costs begins upon
the establishment of technological feasibility of the product, which the Company
has defined as the completion of beta testing of a working product. The
establishment of technological feasibility and the ongoing assessment of the
recoverability of these costs require considerable judgment by management with
respect to certain external factors, including, but not limited to, anticipated
future gross product revenue, estimated economic life and changes in software
and hardware technology. Amounts that could have been capitalized under this
statement after consideration of the above factors were immaterial and,
therefore, no software development costs have been capitalized by the Company to
date.

RESEARCH AND DEVELOPMENT

     Research and development costs are expensed as incurred.

INCOME TAXES

     The Company computes income taxes using the asset and liability method,
under which deferred income taxes are provided for the temporary differences
between the financial reporting basis and the tax basis of the Company's assets
and liabilities. Deferred tax assets and liabilities are measured using
currently enacted tax rates that are expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. A valuation allowance is established when necessary to reduce deferred
tax assets to the amounts expected to be realized.

FOREIGN CURRENCY TRANSLATION

     The functional currency of foreign subsidiaries is the local currency.
Accordingly, assets and liabilities are translated into U.S. Dollars at exchange
rates in effect at the balance sheet date and income and expense accounts at the
average exchange rates during the year. Resulting translation adjustments are
recorded as a separate component of shareholders' equity. The net gains and
losses resulting from foreign currency transactions are recorded in the
consolidated statements of income in the period incurred and were not
significant for any of the periods presented.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

REVENUE RECOGNITION

     The Company's revenue recognition policy is in compliance with the
provisions of the American Institute of Certified Public Accountants' Statement
of Position 97-2, "Software Revenue Recognition." Service revenue is derived
from software porting and development contracts. Product revenue consists of
licensing fees from software application products and operating system and
software development tool products. The Company's customers consist of software
companies, original equipment manufacturers, distributors and end users.

     The Company's revenue is recognized as follows:

     Time and Material Consulting Contracts. The Company recognizes revenue as
services are rendered.

     Fixed-Price Consulting Contracts. Service revenue from fixed-price
contracts is recognized on the percentage-of-completion method, measured by the
cost incurred to date to the estimated total cost for the contract. This method
is used as management considers expended costs to be the best available measure
of contract performance. Contract costs include all direct labor, material and
any other costs related to contract performance. Selling, general and
administrative costs are charged to expense as incurred. Provisions for
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions and estimated
profitability may result in revisions in the estimate of total costs. Any
required adjustments due to these changes are recognized in the period in which
such revisions are determined.

     Product Revenue. Product revenue consists principally of fees from the
licensing and sale of software products. Product licensing fees, including
advanced production royalty payments, are generally recognized when a customer
license agreement has been executed, the software has been shipped, remaining
obligations are insignificant and collection of the resulting account receivable
is probable. The Company recognizes license royalty income as it is reported by
the reseller when it ships its product to distributors.

     Deferred revenue consists of deposits received from customers and
unamortized service contract revenue.

4. INCOME TAXES

     The Company was a Subchapter S Corporation for income tax purposes from
inception to October 15, 1997. Effective October 16, 1997, the Company converted
to a C Corporation and was thereafter responsible for U.S. federal income taxes.
A net deferred tax liability of $445, primarily related to the required
conversion for income tax purposes from the cash basis method to the accrual
basis method of accounting, was recorded at the conversion date to reflect the
Company's net taxable temporary differences.

5. SHAREHOLDER NOTES PAYABLE

     The Company was a Subchapter S Corporation for income tax purposes from
inception to October 15, 1997. Effective October 16, 1997, the Company converted
to a C Corporation. In connection with the conversion, the Company issued notes
payable totaling $2.0 million to the shareholders. Interest accrued at the
applicable federal long-term rate under Section 1274 of the Internal Revenue
Code of 1986, as amended. Although the notes were not due until December 2002,
or earlier if certain conditions were met, the Company paid in full these notes
and related accrued interest on January 30, 1998.

6. BANK LINE OF CREDIT AND NOTES PAYABLE

     At December 31, 1999, the Company had available a $5.0 million secured
domestic revolving line of credit, $1.5 million term loan for the purchase of
equipment and a $4.0 term loan for leasehold improvements. Interest accrues at
the bank's prime rate for the revolving line of credit, the bank's prime rate
plus 0.25% for the equipment term loan and the bank's prime rate plus 0.5% for
the leasehold term loan. The facility fee is $25. Restrictive terms of the lines
require, among other requirements, that the Company maintain a minimum quick
ratio, tangible net worth and debt service ratio, and limits the Company's
ability to pay dividends without the lender's consent. The line of credit is
secured by substantially all of the assets of the Company. As of December 31,
1999 the Company had $464 in standby letters of credit issued and outstanding
under the domestic revolving line of credit.

     In January 1999, the Company signed a ten-year lease for a new corporate
headquarters in Bellevue, Washington, which commenced in October 1999. The
Company has the option to extend the lease for four additional periods of five
years each. The Company must provide a $667 letter of credit as security for the

upon the Company's achieving certain economic goals.

8. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK

     The Company has authorized 10,000,000 shares of convertible preferred
stock. The Board of Directors has the authority to establish and define, in one
or more series, the price, rights, preferences and dividends of authorized but
unissued shares of preferred stock.

     On January 30, 1998, the Company issued 8,333,333 shares of Series A
Convertible Preferred Stock (Preferred Stock) at $1.80 per share. Total
proceeds, net of offering costs, approximated $14.3 million. Concurrent with
this transaction, the Company repurchased 3,333,333 shares of the Company's
common stock from its founders for $6.0 million.

     The rights and preferences of the Preferred Stock are as follows:

     - In the event of any liquidation, dissolution or winding up of the
       Company, the holders of the Preferred Stock would be entitled to receive
       the greater of: (i) an amount in cash equal to $1.80 per share (adjusted
       for stock splits, stock dividends and the like) or (ii), cash in an
       amount equal to the portion of the assets of the Company remaining for
       distribution to shareholders which such shareholder would have received
       if each share of Series A Preferred Stock held had been converted into
       the number of shares of common stock issuable upon the conversion of a
       share of Series A Preferred Stock immediately prior to any liquidation,
       dissolution or winding up of the Company.

     - The Preferred Stock is voluntarily convertible at any time at the option
       of the holder into shares of the Company's common stock at a one-for-one
       conversion. The Preferred Stock is

       automatically convertible upon closing of a Qualified Public Offering, as
       defined in the agreement.

     - Any time following the fifth anniversary of the closing, holders of the
       Preferred Stock have the right to cause the Company to redeem up to 50%
       of the Preferred Stock at the original purchase price. Any time following
       the sixth anniversary of the closing, the holders shall have the right to
       cause the Company to redeem up to 100% of the Preferred Stock at the
       original purchase price.

     - The Preferred Stock converts at a one-for-one conversion rate, and is
       adjusted in certain circumstances to prevent dilution of the preferred
       shareholder's ownership interest.

     - The holders of Preferred Stock have the same voting rights and voting
       powers as common shareholders.

     The Preferred shares were converted into shares of the Company's common
stock in conjunction with the Company's initial public offering on October 20,
1999.

INITIAL PUBLIC OFFERING

     On October 20, 1999, the Company issued 4,000,000 shares of its common

offering were 600,000 shares held by selling shareholders upon exercise of the
underwriters' overallotment option. The net proceeds to the Company from the
offering, net of offering costs of approximately $5.6 million, were
approximately $54.4 million. Concurrent with the initial public offering, each
outstanding share of the Company's mandatorily redeemable preferred stock was
automatically converted into common stock.

Company, have a term of up to 10 years, and shall be granted at a price equal to
the fair market value of the Company's stock.

     The Company has assumed certain options granted to employees of acquired
companies, referred to as acquired options. These options were assumed by the
Company outside of its stock option plans, and are administered as if issued
under their original plans. All of the acquired options have been adjusted to
reflect the price conversion under the terms of the agreements between the
Company and the companies acquired. The acquired options generally become
exercisable over a four-year period and generally expire ten years from the date
of grant. No additional options will be granted under any of the acquired
companies' plans.

1999 EMPLOYEE STOCK PURCHASE PLAN

     On July 21, 1999, the Board of Directors approved the adoption of the
Company's 1999 Employee Stock Purchase (the "1999 Purchase Plan".) Under the
plan, the Company is authorized to sell up to 1,500,000 shares of common stock
in a series of eighteen month offerings. The 1999 Purchase Plan permits eligible
employees to acquire shares of the Company's common stock through periodic
payroll deductions of up to 10% of base cash compensation. The price at which

stock may be purchased is 85% of the lesser of 1) the fair market value of the
Company's common stock on the first day of the applicable offering period or 2)
the fair market value of the shares on the purchase date. The initial offering
period commenced on the effectiveness of the initial public offering. During the
six months ended June 30, 2000, the Company issued 93,815 (unaudited) shares
under the plan.

PROFIT SHARING AND DEFERRED COMPENSATION PLAN

     The Company has a Profit Sharing and Deferred Compensation Plan (Profit
Sharing Plan) under Section 401(k) of the Internal Revenue Code of 1986, as
amended. Substantially all full-time employees are eligible to participate. The
Company, at its discretion, may elect to match the participants' contributions
to the Profit Sharing Plan. Participants will receive their share of the value
of their investments upon retirement or termination, subject to a vesting
schedule. The Company made no matching contributions to the Profit Sharing Plan
during 1998 or 1997. During the year ended December 31, 1999, and for the six
months ended June 30, 2000, the Company made matching contributions to the
Profit Sharing Plan of $514 and $335 (unaudited) respectively.

DEFERRED STOCK OPTION COMPENSATION

     In connection with the grant of certain stock options to employees and
consultants during 1997 and 1999, the Company recorded deferred stock option
compensation of $653 and $1.1 million, respectively, representing the difference
between the estimated fair value of the common stock for accounting purposes and
the option exercise price of such options at the date of grant. Such amount is
presented as a reduction of shareholders' equity and amortized, in accordance
with FASB Interpretation No. 28, on an accelerated basis over the vesting period
of the applicable options (generally four years). During the years ended
December 31, 1997, 1998, 1999, and for the six months ended June 30, 1999 and
2000, the Company expensed approximately $81, $171, $583, $294 (unaudited) and
$318 (unaudited), respectively. The balance will be expensed over the period the
options vest. Compensation expense is decreased in the period of forfeiture for
any accrued but unvested compensation arising from the early termination of an
option holder's services.

     Included in the expensed amounts noted above for the year ended December
31, 1999 is $30 related to options granted to a consultant for services
rendered. As of December 31, 1999, the consultant had earned 20,833 options to
acquire common stock at $1 per share. The Company has recorded the fair value of
the options as of the date the options were earned based on a Black-Scholes
model utilizing a 50% volatility factor and an expected life of 2 years. During
1999, the agreement was terminated.

* Revenue is attributed to countries based on location of customer invoiced.

     BSQUARE has two operating segments, Services and Products. The Services
segment includes design and development of integration tools for the
semiconductor vendors and the original equipment manufacturer market. The
Product segment derives revenue from licensing of software products to original
equipment manufactures and distributing product through resellers. The
accounting policies of the segments are the same as those described in the
summary of significant accounting policies.

     The Company does not track assets or operating expenses by operating
segments. Consequently, it is not practicable to show assets or operating
expenses by operating segments.

(1) Share amounts presented for 1997 to 1999 give effect to the issuance of
    261,391 shares to the former shareholders of BlueWater Systems to effect its
    acquisition by BSQUARE. The transaction was accounted for as a pooling of
    interests.

(2) As the Company incurred a net loss attributable to common shareholders for
    the three- and six-month periods ended June 30, 2000, the effect of common
    stock equivalents and mandatorily redeemable convertible securities are
    excluded in those periods as their effects are anti-dilutive.

16. ACQUISITIONS

BLUEWATER SYSTEMS, INC.

     On January 5, 2000, the Company acquired BlueWater Systems, Inc. in a
transaction accounted for as a pooling of interests. BlueWater Systems, formerly
located in Edmonds, Washington, is dedicated to the design of software
development tool kits and system integration services for the creation of
Windows-based intelligent computing devices. The transaction was effected
through the exchange of 261,391 shares of BSQUARE common stock for all of the
issued and outstanding common shares of BlueWater Systems. The consolidated
financial statements of BSQUARE have been restated for all periods prior to the
merger to include the accounts and operations of BlueWater

MAINBRACE CORPORATION

     On May 24, 2000, the Company acquired Mainbrace Corporation in a
transaction accounted for as a purchase. Mainbrace Corporation, located in
Sunnyvale, California, is a leading IP-licensing and enabling software firm
delivering product solutions to high volume market segments including set-top
boxes, Web-enabled phones, wireless thin clients, and electronic book readers.
Total consideration included the issuance of 627,370 shares of BSQUARE common
stock, and approximately $10,800 in cash. Additionally, the Company assumed
Mainbrace's outstanding vested and unvested employee stock options which were
converted into the right to acquire approximately 173,000 shares of the
Company's common stock. Such assumption of Mainbrace's options by the Company
had a fair market value of approximately $552.

     A summary of the purchase price for the acquisition is as follows:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

     The purchase price was allocated as follows:

                                                         =======
</TABLE>

     The excess of consideration paid over the fair value of the net assets
acquired will be recorded as goodwill and other intangible assets and will be
amortized over periods ranging from two to seven years.

     In accordance with generally accepted accounting principles, the amount
allocated to in-process research and development, which was determined by an
independent valuation, has been recorded as a charge to expense in the second
quarter of 2000 because its technological feasibility had not been established
and it had no alternative future use at the date of acquisition.

     The following table presents unaudited pro forma results of operations as
if the acquisition of Mainbrace had occurred at the beginning of each of the
periods presented. The unaudited pro forma information is not necessarily
indicative of the combined results that would have occurred had the acquisition
taken place at the beginning of the periods presented, nor is it necessarily
indicative of future results.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Mainbrace Corporation

     We have audited the accompanying balance sheet of Mainbrace Corporation as
of December 31, 1999, and the related statements of operations, shareholders'
equity, and cash flows for the year then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

     We conducted our audit in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Mainbrace Corporation at
December 31, 1999, and the results of its operations and its cash flows for the
year then ended, in conformity with accounting principles generally accepted in
the United States.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1999

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BUSINESS

     Mainbrace Corporation (the Company) was incorporated in the state of
California on October 6, 1997. The Company provides design services to leading
OEMs, semiconductor vendors, and technology providers in the United States.

     The Company's activities to date have consisted principally of raising
capital, arranging for facilities, acquiring equipment and licensing rights,
recruiting managerial and technical personnel, and commencing research and
development efforts.

BASIS OF PRESENTATION

     As of December 31, 1999, the Company had working capital of $142,687. For
the year ended December 31, 1999, the Company used cash of approximately
$776,000 in its operating activities. Management has committed that, to the
extent existing resources and anticipated revenues are insufficient to fund the
Company's planned activities, debt or equity financing will be available from
existing investors and others. Based on this commitment, substantial doubt as to
the Company's ability to continue as a going concern for financial reporting
purposes at December 31, 1999 has been alleviated.

REVENUE RECOGNITION

     To date, the Company's revenues have been derived from consulting work. The
Company recognizes consulting revenue as earned, provided that contract
milestones have been reached and customer acceptance has occurred.

ESTIMATES AND ASSUMPTIONS

     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, liabilities, revenue,
and expenses. Actual results may materially differ from those estimates.

CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments with a maturity of
three months or less at the date of purchase to be cash equivalents. The
carrying value of cash and cash equivalents approximates fair value at December
31, 1999.

SIGNIFICANT CONCENTRATIONS

     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of accounts receivable. The
Company's accounts receivable are derived primarily from consulting services to
large OEMs, semiconductor vendors, and technology vendors in the United States.
As of December 31, 1999, three customers represented 15.8%, 35.2%, and 49.0% of
accounts receivable. Three customers accounted for approximately 26.8%, 28.5%,
and 36.8% of revenues in 1999. The Company generally does not require
collateral, performs ongoing credit evaluations of its customers, and to date
has not experienced any material losses.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1999

PROPERTY AND EQUIPMENT

     The Company records property and equipment at cost and calculates
depreciation using the straight-line method over the estimated useful lives of
the assets, generally three years. Leasehold improvements are amortized using
the straight-line method over the shorter of the useful lives or the term of the
lease.

RESEARCH AND DEVELOPMENT

     Research and development expenditures are charged to operations as
incurred. Statement of Financial Accounting Standards No. 86, "Accounting for
the Costs of Computer Software to Be Sold, Leased or Otherwise Marketed,"
requires capitalization of certain software development costs subsequent to the
establishment of technological feasibility. Based on the Company's product
development process, technological feasibility is established upon completion of
a working model. To date, the period between achieving technological feasibility
and the general availability of such software has been short and software
development costs qualifying for capitalization have been insignificant.
Accordingly, the Company has charged all such costs to research and development
expense.

STOCK-BASED COMPENSATION

     The Company accounts for stock-based compensation using the intrinsic-value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and has adopted the disclosure alternative of
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123).

INCOME TAXES

     The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109). Under
this method, deferred tax assets and liabilities are determined based on the
differences between the financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rates that will be in effect
when the differences are expected to reverse.

OTHER COMPREHENSIVE INCOME

     The Company has adopted the provisions of the Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS 130). The
Company has no items of other comprehensive income in the period presented and,
therefore, net loss equals total comprehensive loss for the year ended December
31, 1999.

NET LOSS PER SHARE

     Basic net loss per share is computed using the weighted-average number of
vested outstanding shares of common stock. Diluted net loss per share is
computed using the weighted-average number of shares of vested common stock
outstanding, and, when dilutive, unvested common stock outstanding, potential
common shares from options to purchase common stock using the treasury stock
method and from convertible securities using the as-if-converted bases. All
potential common

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133). SFAS
No. 133 establishes methods for derivative financial instruments and hedging
activities related to those instruments, as well as other hedging activities. At
December 31, 1999, the Company did not hold any derivative instruments and did
not engage in any hedging activities. As a result, the adoption of SFAS 133 is
not expected to have a significant impact on the Company's financial position,
results of operations or cash flows. The Company will be required to implement
SFAS 133, as amended, for the year ending December 31, 2001.

     In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements" (SAB 101). The Company does not
believe its adoption will materially change its financial position, results of
operations, or cash flows.

     In March 2000, the Financial Accounting Standards Board issued FASB
Interpretation No. 44 (FIN 44), "Accounting for Certain Transactions Involving
Stock Compensation -- An Interpretation of APB No. 25." FIN 44 clarifies the
application of APB Opinion No. 25 and, among other issues, clarifies the
following: the definition of an employee for purposes of applying APB Opinion
No. 25; the criteria for determining whether a plan qualifies as a
noncompensatory plan; the accounting consequence of various modifications to the
terms of the previously fixed stock options or awards; and the accounting for an
exchange of stock compensation awards in a business combination. FIN 44 is
effective July 1, 2000, but certain conclusions in FIN 44 cover specific events
that occurred after either December 15, 1998 or January 12, 2000. Mainbrace does
not expect the application of FIN 44 to have a material impact on the Company's
financial position or results of operations.

4. SHAREHOLDERS' EQUITY

COMMON STOCK

     As of December 31, 1999, the Company has reserved 4,770,000 shares of its
common stock for issuance upon exercise of stock options granted and options
available for grant under the Company's Stock Option Plan.

     The Company effected a two-for-one stock split of its outstanding common
stock in December 1999. All shares and per share amounts have been adjusted to
reflect the split.

STOCK OPTION PLAN

     In 1998, the shareholders adopted the 1998 Stock Option Plan (the Plan) for
issuance of common stock to eligible participants. Under this plan, the Company
may grant either nonstatutory or incentive stock options and the option price
per share cannot be less than 85% of fair value in the case of nonstatutory
options, or 100% of fair value in the case of incentive stock options,
determined on the date that the option is granted. All options expire no later
than 10 years from date of grant.

                                      F-33
<PAGE>   96
                             MAINBRACE CORPORATION

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1999

     Stock options granted under the Plan are immediately exercisable and
unvested shares issued are subject to repurchase by the Company. Options and
unvested shares typically vest 25% per year from the date of grant and 1/16 upon
completion of each consecutive three-month period thereafter. Options may be
granted with different vesting terms from time to time. In the event option
holders cease to be employed by the Company, all unvested options are forfeited
and all vested options may be exercised within a 30-day period after
termination; the Company also has the right to repurchase any unvested (but
issued) shares if the holder is no longer employed by the Company. As of
December 31, 1999, approximately 171,000 shares that had been exercised remained
subject to the Company's right of repurchase.

     Pro forma information regarding net loss is required by SFAS 123, and has
been determined as if the Company has accounted for its employee stock options
under the fair-value method of that Statement. The fair value of these options
was estimated at the date of grant using the minimum-value method assuming a
risk-free rate of 6%, an expected life of four years, and no dividends. Changes
in the subjective input assumptions can materially affect the fair value
estimate and, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its stock-based awards to
employees. For the purposes of pro forma disclosures, the estimated fair value
of the options is amortized to expense over the options' vesting period.

     The effect of applying the fair-value method of SFAS 123 to the Company's
stock option awards did not result in pro forma net loss that was materially
different from the amounts reported.

     The option valuation models were developed for use in estimating the fair
value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected option life. Because the
Company's employee stock options have characteristics significantly different
from those of traded options and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

     The effects of applying SFAS 123 on pro forma disclosures are not likely to
be representative of the effects on pro forma disclosures in future years.

     Stock activity under the Stock Option Plan was as follows:

                               DECEMBER 31, 1999

ISSUE OF SERIES A PREFERRED STOCK

     On January 29, 1999, the Company issued 952,380 shares of Series A
convertible preferred stock at $1.00 per share. The Series A shareholder and the
Company also entered into a consulting agreement in January 1999. The Company
provided consulting services to the Series A shareholder in 1999. The shares
were issued at $1.00 per share while the deemed fair value of the preferred
stock at that date was $1.30 per share. The Company recorded the difference
between the issue price and deemed fair market value as a $285,714 reduction in
revenues for the year ended December 31, 1999.

     Each share of Series A convertible preferred stock (preferred stock) is
entitled to voting rights equivalent to the number of shares of common stock
into which each share can be converted and is convertible into common stock at
the quotient obtained by dividing the original issue price of the Series A
preferred conversion price, which shall initially be the original issue price,
and may be charged accordingly. Conversion to common stock occurs automatically
upon a majority vote by holders of preferred stock or upon the closing of an
underwritten public offering, provided certain conditions are met. The Series A
convertible preferred shares are subject to liquidation preferences of $1.00 per
share, plus all declared but unpaid dividends. Series A convertible preferred
shareholders are entitled to noncumulative dividends of $0.10 per share per
annum, if declared by the Board of Directors, and in preference to common stock
dividends.

DEFERRED COMPENSATION

     During the year ended December 31, 1999, in connection with the grant of
stock options to employees, the Company recorded deferred stock compensation of
$2,864,060 representing the difference between the exercise price and the deemed
fair value of the Company's common stock. Deferred compensation is included as a
reduction of shareholders' equity and is being amortized using the graded method
over the vesting period, generally four years. During 1999, the Company recorded
amortization of deferred compensation of $666,860.

5. RELATED PARTY TRANSACTIONS

     Effective April 1, 1998, the Company entered into an arm's-length
consulting agreement with Metis Associates, Inc. (Metis), a company under common
ownership. Under this agreement, Metis agreed to provide consulting services to
the Company until April 2001. This service was provided without charge up to
December 31, 1998. The remaining term of the agreement included a $25,000
monthly fee. The Company recognized costs under this agreement on a
straight-line basis over the term of the contract. On July 1, 1999, the Company
amended its agreement with Metis, where Metis agreed to waive any outstanding
liability and provide consulting services on an "as needed" basis. The Company
has recognized approximately $169,000 in equity as a contribution of services
for the outstanding liability related to the first nine months of the contract.

     The Company had a $125,000 loan outstanding from Metis at December 31,
1998. During 1999, the Company received additional loans of $255,000 from Metis,
due in one year from issuance with interest at 9.00% per annum, compounded
annually. The Company repaid Metis $350,000 of loans during 1999 and has a
balance of $30,000 at December 31, 1999. The Company leases its office space
under a sublease from Metis. The terms of this lease are disclosed in Note 3.

6. INCOME TAXES

     No provision for income taxes has been recorded due to operating losses
with no current benefit.

     As of December 31, 1999, the Company had federal and state net operating
loss carryforwards of approximately $600,000. The net operating loss
carryforwards will begin expiring in 2005 through 2019, if not utilized.

     Utilization of the net operating losses and credits may be subject to a
substantial annual limitation due to the ownership change provisions of the
Internal Revenue Code of 1986 and similar state provisions. The annual
limitation may result in the expiration of net operating losses and credits
before utilization.

     As of December 31, 1999, the Company had deferred tax assets of
approximately $240,000. The deferred tax asset has been fully offset by a
valuation allowance. Deferred tax assets relate primarily to net operating loss
carryforwards. The valuation allowance for deferred tax assets increased by
approximately $154,000 in the year ended December 31, 1999.

7. SUBSEQUENT EVENTS

     In May 2000, the Company entered into an Agreement and Plan of Merger with
an unrelated company to be acquired for approximately $10.8 million in cash and
$9.7 million in stock and stock options.

               NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     The unaudited condensed financial statements have been prepared by
Mainbrace Corporation (the "Company") pursuant to the rules and regulations of
the Securities and Exchange Commission. Certain information and footnote
disclosures, normally included in financial statements prepared in accordance
with generally accepted accounting principles, have been condensed or omitted
pursuant to such rules and regulations. In the opinion of the Company, the
unaudited financial statements reflect all adjustments, consisting only of
normal recurring adjustments, necessary for a fair presentation of the Company's
financial position at March 31, 2000, its operating results and cash flows for
the three months ended March 31, 2000. Interim results are not necessarily
indicative of results for a full year.

2. SUBSEQUENT EVENT

     On May 24, 2000, the Company was acquired by BSQUARE Corporation for
approximately $10.8 million in cash and $9.1 million in stock.

                                      F-40

                        PRO FORMA FINANCIAL INFORMATION

     BSQUARE's acquisition of Mainbrace Corporation will be accounted for under
the purchase method of accounting. Under the purchase method of accounting, the
purchase price is allocated to the assets acquired and liabilities assumed based
on their estimated fair values. The estimated fair values included herein are
based upon preliminary estimates and may not be indicative of the final
allocation of purchase price consideration. Amounts allocable to in-process
research and development will be recorded as one-time charges that would reduce
the goodwill reflected in the Unaudited Pro Forma Condensed Consolidated Balance
Sheet and the related amortization expense reflected in the Unaudited Pro Forma
Condensed Consolidated Statements of Operations. The acquisition is valued at
approximately $24.9 million based on the closing price of BSQUARE's common stock
on May 24, 2000. The amount of the consideration issued to the former
shareholders and option holders of Mainbrace was determined by arms-length
negotiation between the parties.

     The following Unaudited Pro Forma Condensed Consolidated Balance sheet as
of March 31, 2000 gives effect to the acquisition of Mainbrace as if it had
occurred on March 31, 2000 and the Unaudited Pro Forma Condensed Consolidated
Statements of Operations for the year ended December 31, 1999 and the three
months ended March 31, 2000 ("Pro Forma Financial Statements") give effect to
the acquisition of Mainbrace as if it had occurred on January 1, 1999. The Pro
Forma Condensed Consolidated Statements of Operations are based on historical
results of operations of BSQUARE and Mainbrace for the year ended December 31,
1999 and the three months ended March 31, 2000. The Pro Forma Financial
Statements and the accompanying notes ("Pro Forma Financial Information") should
be read in conjunction with and are qualified by the historical financial
statements and notes thereto of BSQUARE and Mainbrace. On January 6, 2000
BSQUARE completed its acquisition of BlueWater Systems Inc. ("BlueWater") in a
transaction accounted for as a pooling of interests. Accordingly, the
accompanying historical financial information of BSQUARE includes the financial
position and results of operations of BlueWater as if BSQUARE and BlueWater had
always been combined.

     The Pro Forma Financial Information is intended for information purposes
only and is not necessarily indicative of the combined results that would have
occurred had the acquisition taken place on January 1, 1999, nor is it
necessarily indicative of results that may occur in the future.

         NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
            (UNAUDITED, DOLLARS IN THOUSANDS, EXCEPT SHARE AMOUNTS)

(a) Reflects the issuance of approximately 627,000 shares of BSQUARE common
    stock to consummate the acquisition of Mainbrace.

(b) Reflects cash paid to selling shareholders and cash other costs associated
    with the acquisition.

(c) Reflects estimated direct acquisition associated with the acquisition.

    assets and is amortized using the straight-line method over periods ranging
    from two to seven years. The estimated fair values of assets acquired and
    liabilities assumed are based upon preliminary estimates and may not be
    indicative of the final allocation of purchase price consideration. Any
    amounts that may be allocable to in process research and development will be
    recorded as one time charges that will reduce the goodwill reflected in the
    Unaudited Pro Forma Condensed Consolidated Balance Sheet and the related
    amortization expense reflected in the Unaudited Pro Forma Condensed
    Consolidated Statements of Operations.

     A summary of the purchase price for the acquisition is as follows:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a corporation to indemnify its directors,
officers, employees and agents against certain liabilities they may incur in
such capacities, including liabilities under the Securities Act of 1933, as
amended (the "Securities Act"), provided they acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
corporation. The registrant's Amended and Restated Articles of Incorporation
(Exhibit 3.1 hereto) and Bylaws (Exhibit 3.2 hereto) require the registrant to
indemnify its officers and directors to the fullest extent permitted by
Washington law.

     Section 23B.08.320 of the WBCA authorizes a corporation to limit or
eliminate a director's liability to the corporation or its shareholders for
monetary damages for breaches of fiduciary duties, other than for (1) acts or
omissions that involve intentional misconduct or a knowing violation of law, (2)
unlawful distributions to shareholders, or (3) transactions from which a
director derives an improper personal benefit. The registrant's Amended and
Restated Articles of Incorporation (Exhibit 3.1 hereto) contain provisions
implementing, to the fullest extent permitted by Washington law, such
limitations on a director's liability to the registrant and its shareholders.

     In addition, the registrant has entered into separate indemnification
agreements with its directors and certain executive officers that could require
the registrant, among other things, to indemnify them against liabilities that
arise because of their status or service as directors or executive officers and
to advance their expenses incurred as a result of any proceeding against them as
to which they could be indemnified.

ITEM 17. UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described above in Item 14, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding), is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the questions whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                      II-3

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933, as amended.

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) of the Securities Act, if,
        in the aggregate, the changes in volume and price represent not more
        than a 20% change in the maximum aggregate offering price set forth in
        the "Calculation of Registration Fee" table in the effective
        registration statement.

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.

          (2) For purposes of determining any liability under the Securities
     Act, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of this offering.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE

To BSQUARE Corporation

     We have audited in accordance with generally accepted auditing standards,
the financial statements of BSQUARE Corporation and subsidiaries included in
this registration statement and have issued our report thereon dated September
7, 2000. Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying schedule is the
responsibility of the company's management and is presented for purposes of
complying with the Securities and Exchange Commission rules and is not part of
the basic financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein relation to the basic financial statements taken as a
whole.
